Testosterone Therapy Adds MI Risk, Especially in Older Men

Risk for incident myocardial infarction increases significantly in the months after starting testosterone therapy, particularly among older men, according to a PLoS ONE study.

Using insurance claims data, researchers compared the incidence of nonfatal MI in some 55,000 men in the year before their first prescription for testosterone therapy with the rate in the 90 days after filling that prescription. As a check, they also compared post- and pre-therapy MI rates for a separate cohort of 165,000 men taking drugs for erectile dysfunction.

In the testosterone cohort, the post-/pre-rate ratio for MI was 1.36, increasing to 2.19 in those 65 and older, and to 3.43 in those 75 and older. Younger men with a history of heart disease also showed an increased risk. The cohort taking sildenafil or tadalafil showed no post/pre effect.

The authors note that their study is limited in that they did not have information on the "serologic or diagnostic indications" for therapy. Nonetheless, they advise clinicians to include serious cardiovascular risks in their discussions with patients when prescribing testosterone.

Testosterone May Undermine Flu Vaccine Effectiveness for Men

 (HealthDay News) – Differences in expression of genes involved in lipid metabolism regulated by testosterone may explain why men have less robust immune responses than women, according to a study published online Dec. 23 in the Proceedings of the National Academy of Sciences.

David Furman, PhD, from the Stanford University School of Medicine in California, and colleagues analyzed the neutralizing antibody response to a trivalent inactivated seasonal influenza vaccine and various immune parameters in 53 women and 34 men of various ages.

The researchers found that women had higher serum expression of inflammatory cytokines and elevated antibody responses to the vaccine regardless of age. A cluster of genes involved in lipid biosynthesis known to be up-regulated by testosterone correlated with the poor antibody response, and men with higher serum testosterone levels and associated gene signatures had the lowest antibody response. The gender-specific differences in immune responses were greatest for the H3N2 influenza strain.

"These results demonstrate a strong association between androgens and genes involved in lipid metabolism, suggesting that these could be important drivers of the differences in immune responses between males and females," Furman and colleagues conclude.

Abstract

 

Calcium Density of Coronary Artery Plaque and Risk of Incident Cardiovascular Events

Importance  Coronary artery calcium (CAC), measured by computed tomography (CT), has strong predictive value for incident cardiovascular disease (CVD) events. The standard CAC score is the Agatston, which is weighted upward for greater calcium density. However, some data suggest increased plaque calcium density may be protective for CVD.

Objective  To determine the independent associations of CAC volume and CAC density with incident CVD events.

Design, Setting, and Participants  Multicenter, prospective observational MESA study (Multi-Ethnic Study of Atherosclerosis), conducted at 6 US field centers of 3398 men and women from 4 race/ethnicity groups; non-Hispanic white, African American, Hispanic, and Chinese. Participants were aged 45-84 years, free of known CVD at baseline, had CAC greater than 0 on their baseline CT, and were followed up through October 2010.

Main Outcomes and Measures  Incident coronary heart disease (CHD) and all CVD events

Results  During a median of 7.6 years of follow-up, there were 175 CHD events and an additional 90 other CVD events for a total of 265 CVD events. With both lnCAC volume and CAC density scores in the same multivariable model, the lnCAC volume score showed an independent association with incident CHD, with a hazard ratio (HR) of 1.81 (95% CI, 1.47-2.23) per standard deviation (SD = 1.6) increase, absolute risk increase 6.1 per 1000 person-years, and for CVD an HR of 1.68 (95% CI, 1.42-1.98) per SD increase, absolute risk increase 7.9 per 1000 person-years. Conversely, the CAC density score showed an independent inverse association, with an HR of 0.73 (95% CI, 0.58-0.91) per SD (SD = 0.7) increase for CHD, absolute risk decrease 5.5 per 1000 person-years, and an HR of 0.71 (95% CI, 0.60-0.85) per SD increase for CVD, absolute risk decrease 8.2 per 1000 person years. Area under the receiver operating characteristic curve analyses showed significantly improved risk prediction with the addition of the density score to a model containing the volume score for both CHD and CVD. In the intermediate CVD risk group, the area under the curve for CVD increased from 0.53 (95% CI, 0.48-0.59) to 0.59 (95% CI, 0.54-0.64), P = .02.

Conclusions and Relevance  CAC volume was positively and independently associated with CHD and CVD risk. At any level of CAC volume, CAC density was inversely and significantly associated with CHD and CVD risk. The role of CAC density should be considered when evaluating current CAC scoring systems .

Garcinia Cambogia: A Safe Supplement for Obesity?

Fighting Obesity with Garcinia Cambogia: Is It Worth the Risks?
Fighting Obesity with Garcinia Cambogia: Is It Worth the Risks?

Garcinia cambogia is yet another entrant in the growing list of natural supplements being marketed as the answer to obesityG. cambogia is most well-known for its use as a spice. This product, which is classified as a fruit, is naturally found throughout southeastern Asia, India and western Africa.1

RELATED: Metabolic Disorders Resource Center

One of nearly 300 species of GarciniaG. cambogia is the one most studied for its weight-loss potential.1G. cambogia grows as a small tree and produces a rusty-red round fruit.2 It is the rind of this fruit that is used for both culinary and therapeutic purposes.2

Background



Obesity is a tremendous health problem, not just in the United States but globally as well. An estimated 1 billion adults worldwide are overweight, and nearly one-third of those are considered clinically obese.3 In the United States alone, the overall cost of obesity was estimated by the CDC to be nearly $150 billion per year.4 

G. cambogia became popular as a weight-loss aid when it was noted to enhance satiety in its native regions.5 A secondary effect of the fruit is its potent laxative action.6 The active ingredient of G. cambogia is hydroxycitric acid (HCA).5 



Science



The mechanism of fat metabolism is complex, and the role of G. cambogia in this process is debatable. 

Metabolically, HCA appears to be the source of early satiety. This acid enters the energy-production process of the Kreb's cycle and ultimately increases hepatic glycogen synthesis and inhibits formation of low-density lipoproteins.5

This is thought to signal to our brains that we have had enough to eat. Some suggest that HCA interacts with the production of the adipose-controlling hormone leptin, but these claims have yet to be substantiated by clinical trials.

In a meta-analysis literature review, researchers identified only 23 trials that met review criteria.7Fewer than half of those ultimately met the proper standards for well-done randomized, placebo-controlled trials. 

After the final data analysis, use of G. cambogia was associated with a very slight (0.88 kg) weight loss over control groups, but also with twice the number of adverse GI effects.

Korean researchers studied the effects of G. cambogia, placebo, and another weight-loss supplement in 86 overweight adults in a 10-week randomized trial.8 At the end of the study, no statistically significant weight loss was found in any of the three groups.

In another small trial, researchers studied 24 overweight adults over two weeks of daily intake of G. cambogia HCA extract.5 In addition to actual weight loss being monitored, 24-hour energy intake was tracked. By the end of the trial, energy intake was reduced by 15% to 30% in the G. cambogia group over placebo, with a very modest trend in weight loss.

Finally, a study in India focused on 60 obese individuals who were randomized to HCA plus two other supplements, or placebo.9 At the end of eight weeks, both HCA groups had a 5% to 6% reduction in weight and BMI. Food intake, total cholesterol, LDL cholesterol, and triglycerides all decreased in the HCA groups, and HDL levels increased. 



Safety

Unfortunately, evidence-based literature demonstrates the potential for adverse events in G. cambogia/HCA. In addition to significant GI upset, increasing reports of hepatic injury are surfacing. 

For example, researchers found that daily feeding with HCA supplement did result in decreased fat accumulation and glucose resistance in obese mice, but at the expense of significant hepatic fibrotic changes and inflammation.1

Green coffee extract: A weight-loss aid?


Green coffee is simply coffee that has not been "cooked." Green coffee products are made from unroasted coffee beans, usually from the plant Coffea arabica.1 Most of the world enjoys coffee products that are manufactured from roasted coffee beans.

The most widely known natural component of coffee is caffeine but, in reality, coffee contains hundreds of bioactive chemicals, many of which are more significant than caffeine.1 Green coffee products have become widely popular as a potential weight-loss aid.

Background

Green coffee extract contains chlorogenic acid, which is derived from a major group of phenolic compounds.2 Green coffee beans contain nearly twice the concentration of chlorogenic acid as do roasted beans. Chlorogenic acid is a major component of many OTC weight-loss products and acts independently of caffeine.2

The theorized mechanism of action by which green coffee produces weight loss is through the inhibition of the enzyme glucose-6-phosphatase.3 In vitro, glucose-6-phosphatase induces the enzymatic process of glucose production in the liver.3 It is this step in the metabolic pathway that researchers attribute to the known reduction of glycemic disorders in long-term coffee-

drinkers.4 

Science

Green coffee extract is believed to aid weight loss. One trial evaluated the responses of 16 overweight adults who had been randomized to high-dose extract, low-dose extract, or placebo in a 22-week study.5 Body weight decreased by a mean of 8 lbs, with a mean drop in body fat of more than 4%.5 

In another study, 50 volunteers with body mass indices >25 were randomized to placebo or to treatment with green coffee extract.6 After 60 days, members of the treatment group had lost an average of 5.7% of their body weight, with a shift in the muscle-mass-to-fat-mass ratio of +4.1%/-0.7% from baseline.6 

In a trial designed to compare the effect of green coffee vs. roasted coffee on BP measurements, researchers randomized more than 200 subjects to either a placebo coffee drink or a drink with low, medium, or high chlorogenic-acid content.7

Each participant drank one cup of the treatment coffee per day and recorded BP readings for one month. At the end of the trial, not only were the BP readings of the placebo group higher than the BP readings of the treatment group, but a definite dose-response curve for the three treatment dose levels also was seen.

This indicates that the beneficial effect of coffee intake on BP has nothing to do with caffeine, but rather with the chlorogenic acid content. These findings have been validated by multiple studies examining different green coffee extract concentrations and populations.8, 9 In each trial, a statistically significant reduction of systolic BP was seen with no documented adverse effects.

Researchers looking at human vasoreactivity monitored nitric oxide activity in individuals after daily intake of a measured amount of green coffee extract. For four months, parameters indicative of endothelial function were monitored daily. At the end of the test period, the vasodilatory response was found to be significantly higher in the test group than in the placebo group, and total plasma homocysteine levels were also lower than at baseline.10 

A small lab study using human cell culture lines focused on the chemoprotective and antigenotoxic activities of green coffee extract.11 Human colon and liver cells were treated with a dose-calculated solution of chlorogenic acid and cultured under the same conditions as the placebo cell cultures. Both cell lines were then tested for levels of oxidative stress, such as membrane disruption, DNA damage, and cell death.

Cells exposed to the chlorogenic acid solution showed markedly lower levels of these oxidative injuries than did the untreated cells. 



Safety, how supplied, dose, and cost

Few adverse reactions have been noted with green coffee extract use. The extract is supplied in a variety of ways, including as liquid extract, powder or liquid-filled capsules, or a drink. The dose is widely variable based both on body mass and age.

Marketed green coffee extract is often standardized to contain more than 50% chlorogenic acid. Average cost for a typical month's supply ranges from $20 to $30, regardless of the dosage form. 



Summary

While further study is needed, green coffee extract appears to be safe and somewhat effective in increasing the efficacy of regular weight-loss methods.

Mediterranean Diet Protects Against Diabetes, Regardless of Weight Loss

Even if it doesn't lead to weight loss, a Mediterranean diet could help prevent type 2 diabetes, according to a subanalysis of the PREDIMED study published in the Annals of Internal Medicine.

Some 3500 adults without diabetes but at high cardiovascular risk were randomized to a Mediterranean diet supplemented by either extra-virgin olive oil or nuts or to a low-fat diet (control). Calorie restriction or increased physical activity was not advised.

After 4 years, diabetes had developed in 6.9% of the olive oil group, 7.4% of the nuts group, and 8.8% of controls. After multivariable adjustment, there was a significant, 40% reduction in diabetes risk in the olive oil group, but no such reduction in the nuts group. The differences in outcome appeared unrelated to weight loss.

The authors conclude that PREDIMED "provides strong evidence that long-term adherence to a Mediterranean diet supplemented with [olive oil] without energy restrictions ... results in a substantial reduction in the risk for type 2 diabetes among older persons with high cardiovascular risk."

Mediterranean Diet + Extra-Virgin Olive Oil Cuts Diabetes Risk

 (HealthDay News) – A Mediterranean diet enriched with extra-virgin olive oil (EVOO) is associated with reduction in the risk of new-onset diabetes among older adults at high risk for cardiovascular disease, according to a study published in the Jan. 7 issue of the Annals of Internal Medicine.

Jordi Salas-Salvadó, MD, PhD, from the Instituto de Salud Carlos III in Madrid, and colleagues examined the efficacy of Mediterranean diets for the primary prevention of diabetes in a cohort of 3,541 patients without diabetes, aged 55–80 years, at high cardiovascular risk. Participants were randomly assigned and stratified to receive one of three diets: Mediterranean diet supplemented with EVOO, Mediterranean diet supplemented with nuts, or a control diet (low-fat dietary advice). No weight loss or physical activity interventions were included.

The researchers found that, during follow-up, the rates of new-onset diabetes were 16, 18.7, and 23.6 per 1,000 person-years, respectively, for the Mediterranean diet supplemented with EVOO, Mediterranean diet supplemented with nuts, and control diet. After multivariate adjustment, the hazard ratios for Mediterranean diet supplemented with EVOO and for the Mediterranean diet supplemented with nuts were 0.6 (95% confidence interval, 0.43–0.85) and 0.82 (95% confidence interval, 0.61–1.1), respectively, compared with the control diet.

"A Mediterranean diet enriched with EVOO but without energy restrictions reduced diabetes risk among persons with high cardiovascular risk," the authors write.

The Fundación Patrimonio Comunal Olivarero and Hojiblanca, the California Walnut Commission, the Borges Mediterranean Group, and Morella Nuts donated the olive oil, walnuts, almonds, and hazelnuts used in the study, respectively.

Skip the Soda to Avoid Cancer

The most common type of endometrial cancer occurred almost 80% more often in postmenopausal women who regularly consumed sugar-sweetened drinks.

A number of previous studies link the consumption of sugar-sweetened beverages to an increased risk of obesity and type-2 diabetes.  Maki Inoue-Choi, from the University of Minnesota School of Public Health (Minnesota, USA), and colleagues analyzed data collected by the Iowa Women's Health Study, involving women ages 55 to 69 years. The final analysis included 23,039 women who had a mean age of 61.6 at enrollment. During follow-up from 1986 to 2010, 592 women had diagnoses of invasive endometrial cancer, consisting of 506 type 1 (endometroid) cancers and 89 type II (nonendometroid) cancers. The team found that factors associated with endometrial cancer were older age, higher BMI, higher waist-hip ratio, history of diabetes, early menarche, delayed menopause, any estrogen therapy. Smoking and increasing number of live births were associated with lower risk. In an unadjusted analysis, the researchers calculated that an increasing intake of sugar-sweetened drinks (excluding fruit juices) had a dose-dependent association with type I endometrial cancer/  Women in the highest quintile of sugared beverage consumption had a 72% higher risk of type I endometrial cancer, as compared with women in the lowest quintile. After adjustment for BMI, the resulting relative risk for comparison of the highest and lowest quintiles of consumption increased to 78%.  A separate analysis of fruit juice consumption yielded relative risks that were 38% and 48% higher in the unadjusted and adjusted models.  The study authors submit that: “Higher intake of [sugar-sweetened beverages] and sugars was associated with an increased risk of type I, but not type II, endometrial cancer.”

Junk Food May Compromise Brain Functions

Consuming foods abundant in fats or sugar may have a detrimental and damaging effect on cognitive skills, suggests a lab animal model.

A plethora of previous studies suggest deleterious effects of routine consumption of fat-or sugar-laden foods. Margaret J. Morris, from the University of New South Wales (Australia), and colleagues studied the impact of a diet high in fat and sugar on laboratory rats. The researchers observe that such foods resulted in memory impairments, after just one week. Specifically, the cognitive impairment was related to place recognition – where the animals showed poor ability to notice when an object have been moved to a new location. The animals also had inflammation of the hippocampal region of the brain, which is associated with spatial memory. Study authors report that: "These results show that relatively short exposures to diets rich in both fat and sugar or rich in sugar, impair .... memory … and suggest a role for oxidative stress and neuroinflammation in this impairment.”

Low Vitamin B12 Levels Raise Bone Risks

Older men with low levels of vitamin B12 may be at increased risk for bone fractures.

While most commonly associated with postmenopausal women, bone fractures can occur in older men.  Catharina Lewerin, from the University of Gothenburg (Sweden), and colleagues assessed vitamin B12 levels in 1000 Swedish men, average age 75 years. The team observed that those subjects with low B12 levels were more likely than those with normal levels to suffer a bone fracture. Specifically, men with the very lowest B12 levels were 70% more likely to incur a bone fracture, with a propensity for the fracture of the lumbar spine, where there was up to 120% greater chance of fracture.  The study authors cite their "novel data showing that low levels of [vitamin B12] in predicting incident fracture in elderly men.”

Progesterone May Preserve Memory & Cognition

Levels of progesterone may correlate to verbal memory and global cognition, among women who were newly postmenopausal.

Previous studies have suggested that changes in hormone levels that occur after menopause may influence cognition and mood.  Victor Henderson, from Stanford University (California, USA), and colleagues analyzed data collected on 643 healthy postmenopausal women, ages 41 t0 84 years who were not on hormone replacement therapy, who were enrolled in the Early Versus Late Intervention Trial with Estradiol (ELITE) study.  The researchers conducted neuropsychological tests to gauge memory and cognition, and screened for various hormone levels: estradiol, estrone, progesterone, testosterone, and sex hormone-binding globulin.  They found that levels of progesterone appeared to be tied to verbal memory and global cognition among women who were in early postmenopause. The higher the levels of progesterone, , the better the outcomes on tests of verbal memory and global cognition in these younger women.

Shingles an Independent Predictor of Vascular Disease

People who experience herpes zoster (HZ), especially in young adulthood, face increased risks for transient ischemic attack (TIA), stroke, and myocardial infarction (MI), according to a retrospective study in Neurology.

Using a U.K. general practice database, researchers matched some 105,000 zoster cases with 210,000 controls. Vascular events were recorded for up to 24 years after zoster occurrence.

After adjustment for vascular risk factors, herpes zoster was associated with significantly increased risks for TIA and MI but not stroke. In analyses limited to zoster before age 40, risk increases were significant for TIA (hazard ratio, 2.4), MI (HR, 1.5), and stroke (HR, 1.7).

The researchers suggest that the herpes zoster vaccine be offered to adults with risk factors for vascular disease, "irrespective of age, to reduce the associated risk of HZ." They also advocate screening for vascular risk factors in patients with zoster, particularly younger adults "in whom intervention may have the most impact."

Aspirin in type 2 diabetes, a randomised controlled study: effect of different doses on inflammation, oxidative stress, insulin resistance and endothelial function 
International Journal of Clinical Practice,
 12/27/2013  Clinical Article

Raghavan RP, et al. – The effect of aspirin upon platelet function is well documented although experimental studies suggest that aspirin may also affect oxidative stress, vascular inflammation, endothelial dysfunction and dysglycaemia. The optimal dose of aspirin for cardiovascular protection in type 2 diabetes is still debated. The authors examined the effects of different doses of aspirin upon these novel markers of cardiovascular risk and any association between aspirin–mediated changes in these markers. Aspirin exhibited no significant dose–dependent effect on markers of vascular inflammation, oxidative stress, insulin resistance and endothelial function (photoplethysmography) when used in type 2 diabetes over a 2–week period.

Methods

  • Subjects with type 2 diabetes attended for baseline evaluation including BMI, glycaemic and lipid markers, endothelial function (photoplethysmography), insulin resistance (HOMA), inflammation (sVCAM-1 and Hs-CRP) and markers of oxidative stress [total anti-oxidant status (TAOS and FRAP), whole blood total glutathione (GSH) assays].
  • Subjects then received in random, sequential, blinded fashion aspirin 75 mg day-1, aspirin 300 mg day-1, aspirin 3.6 g day-1 or placebo for 2 weeks with a 2-week washout.
  • The above investigations were repeated after each intervention.
  • Aspirin-related changes compared with placebo were analysed using repeated measures ANOVA.

Results

  • Subjects = 17 (M – 12; F – 5), mean age – 57.4 ± 9.1 years (mean ± 1 SD), HbA1c – 63 ± 13 mmol mol-1(7.9 ± 1.2%), total cholesterol 4.57 ± 1.01 mmol l-1.
  • At baseline TAOS value was 59.3 ± 9.7 μM AEAC (Ascorbate Equivalent Anti-oxidant Concentration), glutathione 302.2 ± 183.3 mmol l-1 and FRAP 0.86 ± 0.23 mM FeII.
  • None of the aspirin doses had a significant impact upon BMI, blood pressure, lipid parameters, insulin sensitivity (HOMA), FRAP, TAOS, GSH, endothelial function, glycaemic control (fructosamine) or inflammation (sVCAM-1 and HsCRP).

Transfer of omega-3 fatty acids across the blood-brain barrier after dietary supplementation with a docosahexaenoic acid (DHA)-rich omega-3 fatty acid preparation in patients with Alzheimer's disease: the OmegAD study 
Journal of Internal Medicine,
 01/12/2014  Evidence Based Medicine  Clinical Article

Levi YF, et al. – Little is known about the transfer of essential fatty acids (FAs) across the human blood–brain barrier (BBB) in adulthood. In this study authors investigated whether oral supplementation with omega–3 (n–3) FAs would change the FA profile of the cerebrospinal fluid (CSF). Oral supplementation with n–3 FAs conferred changes in the n–3 FA profile in CSF, suggesting transfer of these FAs across the BBB in adults.

Methods

  • A total of 33 patients (18 receiving the n–3 FA supplement and 15 receiving placebo) were included in the study.
  • These patients were participants in the double–blind, placebo–controlled randomised OmegAD study in which 204 patients with mild Alzheimer's disease (AD) received 2.3 g n–3 FA [high in docosahexaenoic acid (DHA)] or placebo daily for 6 months.
  • CSF FA levels were related to changes in plasma FA and to CSF biomarkers of AD and inflammation.

Results

  • At 6 months, the n–3 FA supplement group displayed significant increases in CSF (and plasma) eicosapentaenoic acid (EPA), DHA and total n–3 FA levels (P < 0.01) whereas no changes were observed in the placebo group.
  • Changes in CSF and plasma levels of EPA and docosapentaenoic acid were strongly correlated, in contrast to those of DHA.
  • Changes in DHA levels in CSF were inversely correlated with CSF levels of total and phosphorylated tau, and directly correlated with soluble interleukin–1 receptor type II.
  • Thus, the more DHA increased in CSF, the greater the change in CSF AD/inflammatory biomarkers.

Effect of vitamin E and memantine on functional decline in Alzheimer disease: The TEAM-AD VA cooperative randomized trial 
JAMA, 01/12/2014  Evidence Based Medicine  Clinical Article

Dysken MW, et al. – Although vitamin E and memantine have been shown to have beneficial effects in moderately severe Alzheimer disease (AD), evidence is limited in mild to moderate AD. To determine if vitamin E (alpha tocopherol), memantine, or both slow progression of mild to moderate AD in patients taking an acetylcholinesterase inhibitor. Among patients with mild to moderate AD, 2000 IU/d of alpha tocopherol compared with placebo resulted in slower functional decline. There were no significant differences in the groups receiving memantine alone or memantine plus alpha tocopherol. These findings suggest benefit of alpha tocopherol in mild to moderate AD by slowing functional decline and decreasing caregiver burden.

Methods

  • Double–blind, placebo–controlled, parallel–group, randomized clinical trial involving 613 patients with mild to moderate AD initiated in August 2007 and concluded in September 2012 at 14 Veterans Affairs medical centers.
  • Participants received either 2000 IU/d of alpha tocopherol (n = 152), 20 mg/d of memantine (n = 155), the combination (n = 154), or placebo (n = 152).
  • Alzheimer’s Disease Cooperative Study/Activities of Daily Living (ADCS–ADL) Inventory score (range, 0–78).
  • Secondary outcomes included cognitive, neuropsychiatric, functional, and caregiver measures.

Results

  • Data from 561 participants were analyzed (alpha tocopherol = 140, memantine = 142, combination = 139, placebo = 140), with 52 excluded because of a lack of any follow–up data.
  • Over the mean (SD) follow–up of 2.27 (1.22) years, ADCS–ADL Inventory scores declined by 3.15 units (95% CI, 0.92 to 5.39; adjusted P = .03) less in the alpha tocopherol group compared with the placebo group.
  • In the memantine group, these scores declined 1.98 units less (95% CI, -0.24 to 4.20; adjusted P = .40) than the placebo group’s decline.
  • This change in the alpha tocopherol group translates into a delay in clinical progression of 19% per year compared with placebo or a delay of approximately 6.2 months over the follow–up period.
  • Caregiver time increased least in the alpha tocopherol group.
  • All–cause mortality and safety analyses showed a difference only on the serious adverse event of “infections or infestations,” with greater frequencies in the memantine (31 events in 23 participants) and combination groups (44 events in 31 participants) compared with placebo (13 events in 11

Serum lycopene, lutein and zeaxanthin, and the risk of Alzheimer's disease mortality in older adults 
Dementia and Geriatric Cognitive Disorders,
 01/12/2014  Clinical Article

Lycopene S, et al. – Oxidative stress is implicated in the pathogenesis of Alzheimer's disease (AD). Accumulating evidence shows that antioxidant–rich food reduces the risk of AD by inhibiting oxidative stress. This study investigates whether serum levels of carotenoids were associated with the risk of AD mortality in a nationally representative sample of US adults. High serum levels of lycopene and lutein+zeaxanthin are associated with a lower risk of AD mortality in adults. The findings suggest that a high intake of lycopene– or lutein+zeaxanthin–rich food may be important for reducing the AD mortality risk.

Music-Based Multitasking Training Improves Cognition & Mental Health

Six months of a music-based multitasking training regimen exerts beneficial effects on thinking, memory, mood, and anxiety.

Developed in the early 1900s, music-based multitasking training is a specific regimen which has been shown to be effective in improving gait and reducing falls.  Melany Hars, from Geneva University Hospitals (Switzerland), and colleagues studied 134 men and women, average age 75 years, who were all at increased risk for falls but who did not live in a nursing home or other facility. These subjects were randomly divided into a study group that attended hour-long music-based multitasking sessions once a week for 25 weeks, or a comparison group that just kept up their normal lifestyles and did not attend training sessions.  At the beginning of the study, both groups underwent assessments of mental function and mood. After six months, the 66 adults who participated in the music training sessions showed improved cognitive function, particularly on a test of their degree of sensitivity to interference, and decreased anxiety, as compared to the group that had not done the training.

Mechanisms of spontaneous resolution of acute gouty inflammation 
Current Rheumatology Reports, 01/05/2014  Review Article

Steiger S, et al. – Acute gout is an auto–inflammatory disease characterized by self–limiting inflammation in response to the deposition of monosodium urate (MSU) crystals in the joints or tissues. This review will highlight mechanisms that limit acute inflammation triggered by MSU crystals and suggests areas for further research.

Increased cardiovascular mortality associated with gout: A systematic review and meta-analysis 
European Journal of Preventive Cardiology, 01/05/2014  Evidence Based Medicine  Review Article

Clarson LE, et al. – Hyperuricaemia, the biochemical precursor to gout, has been shown to be an independent risk factor for mortality from cardiovascular disease (CVD), although studies examining the clinical phenomenon of gout and risk of CVD mortality report conflicting results. This study aimed to produce a pooled estimate of risk of mortality from cardiovascular disease in patients with gout. Gout increases the risk of mortality from CVD and CHD, but not myocardial infarction, independently of vascular risk factors.

Musculoskeletal pain linked to greater cardiovascular risk 
Among more than 5,300 adults ages 45 and older, those with a history of chronic musculoskeletal pain were more likely to suffer from cardiovascular disease than those without pain, a U.K. study showed. The link between chronic musculoskeletal pain and heart problems was more pronounced among people older than 65, researchers reported in the European Journal of Pain. MedWire News (U.K.)

Early Vitamin D Status in Multiple Sclerosis Predicts Course

Higher vitamin D levels within a year after the early manifestations of multiple sclerosis are linked to better clinical outcomes, according to aJAMA Neurology article.

For 5 years, investigators followed over 400 patients suspected to be in the early stage of MS. Those with serum 25-hydroxyvitamin D levels of 50 nmol/L (20 ng/mL) or more during the first year, when compared with patients having lower values, showed less progression during the 5 years' observation. The higher-level patients had "a 4-times lower change in T2 lesion volume, a 2-fold lower rate of brain atrophy, and lower disability."

The authors note that their findings concur with earlier evidence although they don't offer a possible explanation for the effect. They say the results "suggest that identification and correction of vitamin D insufficiency has an important role in the early treatment of MS."

Access to Firearms Linked to Elevated Mortality Risk

Firearm access in the U.S. is associated with increased risk for death, both by suicide and homicide, according to a meta-analysis in the Annals of Internal Medicine.

Researchers analyzed the results of 15 observational studies that looked at firearm ownership or availability in the home. People with access to firearms had an increased risk for suicide (odds ratio, 3.24), compared with people without access. Firearm access was also associated with being the victim of a homicide (OR, 1.94), and for women, the risk was even higher (OR, 2.84).

An editorialist says that the meta-analysis likely underestimates mortality from firearm access because the authors did not include population-level studies.

High Cholesterol Feeds Breast Cancer

A byproduct of cholesterol fuels the growth and spread of estrogen receptor (ER)-positive breast cancers.

Previously, a number of studies have suggested a connection between elevated cholesterol and breast cancer risk, but the mechanism for this action has remained unclear.  Donald McDonnell, from Duke University School of Medicine (North Carolina, USA), and colleagues studied whether an estrogen-like cholesterol compound, that 27-hydroxycholesterol – or 27HC, exerts a role in estrogen receptor (ER)-positive breast cancers. Using mouse models, the team demonstrated that the direct involvement of 27HC in breast tumor growth, as well as the aggressiveness of the cancer to spread to other organs. They also noted that the activity of this cholesterol metabolite was inhibited when the lab animals were treated with anti-estrogens or when exposure to 27HC was halted. The studies were substantiated using human breast cancer tissue. Additionally, the researchers found that the human tissue showed a direct correlation between the aggressiveness of the tumor and an abundance of the enzyme that makes the 27HC molecule. The study authors submit that: " lowering circulating cholesterol levels or interfering with its conversion to 27HC may be a useful strategy to prevent and/or treat breast cancer.”

Acute effects of red wine on cytochrome P450 eicosanoids and blood pressure in men 
Journal of Hypertension, 12/28/2013  Clinical Article

Barden AE, et al. – The vasodilation accompanying acute alcohol ingestion is hard to reconcile with the strong evidence linking chronic alcohol consumption with hypertension. Cytochrome P450 (CYP450) eicosanoids derived from arachidonic acid include vasodilator epoxyeicosatrienoic acids (EETs) and the vasoconstrictor 20–hydroxyeicosatrienoic acid (20–HETE). Acute consumption of alcohol as red wine results in a relative increase in plasma levels of the vasoconstrictor 20–HETE over 24 h without affecting EETs, and may contribute to the BP elevation that associates with a binge drinking pattern or be a homeostatic response to the acute fall in BP induced by alcohol.

Methods

  • Twenty–five normotensive men were randomly assigned to drink either 375 ml of red wine (41 g of alcohol) or the equivalent volume of DRW or water, with a light meal on 3 separate days.
  • Ambulatory BP and heart rate were measured over 24 h.
  • Blood samples were obtained before and 2, 4 and 24 h after beverage consumption.

Results

  • Blood pressure fell in the first 4 h after red wine consumption (P=0.001), but was significantly higher after 20 h (P=0.037).
  • Plasma 20–HETE fell in the 2 h after consumption of all beverages, but over the 24–h period was relatively higher after red wine consumption (P=0.025).
  • The largest difference in 20–HETE was 2 h after consuming red wine and coincided with the highest blood alcohol level.
  • There were no significant effects of red wine on plasma EETs.

South American Berry May Protect from Alzheimer’s

An extract of the palm acaí berry (Euterpe oleraceae Mart.) inhibits beta-amyloid protein aggregation, in a lab model.

The South American palm acaí berry (Euterpe oleraceae Mart.) is abundant in polyphenols and other antioxidants.  Daphne Wong, from the University of Adelaide (Australia), and colleagues employed a laboratory model of Alzheimer's Disease, in which cells were pretreated with acai extract and then exposed to a specific form of beta-amyloid. The team found that the acai extract inhibited the aggregation of beta-amyloid proteins, thereby preventing brain cell damage and death from oxidative stress. The study authors report that: "In comparison with other phenolics, acaí was most effective at inhibiting [beta-amyloid] aggregation. Inhibition of β-amyloid aggregation may underlie a neuroprotective effect of acaí.”

Heart Disease Risk Rises with Osteoarthritis

People who are affected by osteoarthritis of the hip or knee are at elevated risk for ischemic heart disease and congestive heart failure.

Recently, scientists suggest that inflammation plays a role in osteoarthritis, considered most often to be a disease of "wear and tear."  M. Mushfiqur Rahman, from the University of British Columbia (Canada), and colleagues analyzed data collected from 600,000 men and women. The team found that men older than 65 years with osteoarthritis were at 15% increased risk for hospitalization for cardiovascular disease. In addition, women older than 65 years had a 17% increase in cardiovascular risk; women younger than 65 years were 26% increased risk.  The study authors submit that: "This prospective longitudinal study suggests that I osteoarthritis] is associated with an increased risk of [cardiovascular disease]."

High Fiber, Fruit/Vegetable Intake Cuts Stroke Risk in T2DM

 (HealthDay News) – For Japanese patients with type 2 diabetes, increased dietary fiber and fruit and vegetable intake is associated with reduced risk of stroke, according to a study published in the December issue of Diabetes Care.

Shiro Tanaka, PhD, from Kyoto University in Japan, and colleagues examined the correlation between fiber-rich food consumption and cardiovascular disease in a cohort of 1,414 patients with type 2 diabetes without history of cardiovascular disease, aged 40–70 years, and whose hemoglobin A1c values were ≥6.5%. Participants completed a dietary survey.

During a median follow-up of 8.1 years, the researchers identified 68 strokes and 96 cases of coronary heart disease. Intake of dietary fiber in the fourth vs. the first quartile was associated with a hazard ratio of 0.39 for stroke (P=0.12); for fruits and vegetable intake, the hazard ratio was 0.35 (P=0.04). No significant associations were observed for coronary heart disease. Per 1g increase, the hazard ratio for soluble fiber was smaller (0.48; P<0.01) than for total or insoluble dietary fiber (0.82 and 0.79, respectively; P<0.01).

"Increased dietary fiber, particularly soluble fiber, and vegetables and fruits were associated with lower incident stroke but not coronary heart disease in patients with type 2 diabetes," the authors write.

Daily Walking Linked to Decreased Cardiovascular Risk

 (HealthDay News) – For adults at high cardiovascular risk with impaired glucose tolerance, baseline and change in objectively-assessed ambulatory activity are associated with reduced risk of cardiovascular events, according to a study published online Dec. 20 in The Lancet.

Thomas Yates, PhD, from the NIHR Leicester-Loughborough Diet, Lifestyle, and Physical Activity Biomedical Research Unit in the United Kingdom, and colleagues examined the correlation between baseline and change in ambulatory activity and the risk of cardiovascular events. The authors used data from 9,306 participants from the NAVIGATOR trial with impaired glucose tolerance and with existing cardiovascular disease or with at least one cardiovascular risk factor. Participants were followed for an average of six years for cardiovascular events (defined as cardiovascular mortality, non-fatal stroke, or myocardial infarction). Ambulatory activity was measured at baseline and 12 months by pedometer.

The researchers identified 531 cardiovascular events during 45,211 person-years of follow-up. Both baseline ambulatory activity and change in ambulatory activity correlated inversely with cardiovascular event risk (hazard ratios per 2,000 steps per day, 0.90 and 0.92, respectively). The association for change in ambulatory activity persisted after adjustment for changes in body mass index and other potentially confounding variables at 12 months.

"In individuals at high cardiovascular risk with impaired glucose tolerance, both baseline levels of daily ambulatory activity and change in ambulatory activity display a graded inverse association with the subsequent risk of a cardiovascular event," the authors write.

Several authors disclosed financial ties to pharmaceutical companies, including Novartis, which funded the study.

Body-mass index and mortality among adults with incident type 2 diabetes 
New England Journal of Medicine, 01/18/2014  Evidence Based Medicine  Clinical Article

Tobias DK, et al. – The relation between body weight and mortality among persons with type 2 diabetes remains unresolved, with some studies suggesting decreased mortality among overweight or obese persons as compared with normal–weight persons (an “obesity paradox”). Authors observed a J–shaped association between BMI and mortality among all participants and among those who had ever smoked and a direct linear relationship among those who had never smoked. They found no evidence of lower mortality among patients with diabetes who were overweight or obese at diagnosis, as compared with their normal–weight counterparts, or of an obesity paradox.

Methods

  • They studied participants with incident diabetes from the Nurses' Health Study (8970 participants) and Health Professionals Follow–up Study (2457 participants) who were free of cardiovascular disease and cancer at the time of a diagnosis of diabetes.
  • Body weight shortly before diagnosis and height were used to calculate the body–mass index (BMI, the weight in kilograms divided by the square of the height in meters).
  • Multivariable Cox models were used to estimate the hazard ratios and 95% confidence intervals for mortality across BMI categories.

Results

  • There were 3083 deaths during a mean period of 15.8 years of follow–up.
  • A J–shaped association was observed across BMI categories (18.5 to 22.4, 22.5 to 24.9 [reference], 25.0 to 27.4, 27.5 to 29.9, 30.0 to 34.9, and >=35.0) for all–cause mortality (hazard ratio, 1.29 [95% confidence interval {CI}, 1.05 to 1.59]; 1.00; 1.12 [95% CI, 0.98 to 1.29]; 1.09 [95% CI, 0.94 to 1.26]; 1.24 [95% CI, 1.08 to 1.42]; and 1.33 [95% CI, 1.14 to 1.55], respectively).
  • This relationship was linear among participants who had never smoked (hazard ratios across BMI categories: 1.12, 1.00, 1.16, 1.21, 1.36, and 1.56, respectively) but was nonlinear among participants who had ever smoked (hazard ratios across BMI categories: 1.32, 1.00, 1.09, 1.04, 1.14, and 1.21) (P=0.04 for interaction).
  • A direct linear trend was observed among participants younger than 65 years of age at the time of a diabetes diagnosis but not among those 65 years of age or older at the time of diagnosis (P<0.001 for interaction).

Anti-Cancer Effects of Grape Seed Extract

An active component of grape seed extract induces cell death in prostate cancer cells, in a laboratory model.

Previously, a number of studies have suggested that grape seed extract may have anti-cancer effects.  Chapla Agarwal, from the University of Colorado Cancer Center (Colorado, USA), and colleagues studied the effects of the most active component of grape seed extract, B2G2, showing that the compound induces cell death (apoptosis) in prostate cancer cells while leaving healthy cells unharmed, in a laboratory model.  The team submits that: "we report B2G2 chemical synthesis at gram-quantity with equivalent biological efficacy against human [prostate cancer) cell lines and same molecular targeting profiles at key transcription factors level. The synthetic B2G2 will stimulate more research on prostate and possibly other malignancies in preclinical models and clinical translation.”

Exercise May Improve Prostate Cancer Outcome

By reducing adverse changes to the shape of blood vessels, exercise may improve outcomes in men with prostate cancer.

Previously published studies report that men who engage in higher levels of physical activity are at a lower risk of prostate cancer recurrence and mortality, as compared with men who participate in little or no physical activity. Erin Van Blarigan, from the University of California/San Francisco (UCSF; California, USA), and colleagues investigated whether prediagnostic physical activity was associated with prostate tumor blood vessel regularity among 572 men enrolled in the Health Professionals Follow-up Study. Prediagnostic physical activity was determined through analysis of questionnaire answers. Blood vessel regularity was established by semiautomated image analysis of the tumor samples. Blood vessels that are perfect circles are considered the ideal shape and given a score of 1. Higher values indicate less regular blood vessels.  The researchers found that men with the fastest walking pace (3.3 to 4.5 miles per hour) prior to diagnosis had 8% more regularly shaped blood vessels compared with men with the slowest walking pace (1.5 to 2.5 miles per hour).  The lead author comments that: "In this study, we found that men who reported walking at a brisk pace had more regularly shaped blood vessels in their prostate tumors compared with men who reported walking at a less brisk pace.  Our findings suggest a possible mechanism by which exercise may improve outcomes in men with prostate cancer.  Our study supports the growing evidence of the benefits of exercise, such as brisk walking, for men with prostate cancer."

Caffeine Enhances Memory

Whether present in coffee or tea, caffeine exerts a positive effect on long-term memory.

A number of previous studies have reported cognitive-enhancing effects of caffeine.  Michael Yassa, from Johns Hopkins University (Maryland, USA), and colleagues explored the effect of caffeine to strengthen memories to reduce forgetting over a 24-hour period.  The researchers conducted a double-blind trial; participants who did not regularly eat or drink caffeinated products received either a placebo or a 200-milligram caffeine tablet five minutes after studying a series of images. Salivary samples were taken from the participants before they took the tablets to measure their caffeine levels. Samples were taken again one, three and 24 hours afterwards. The next day, both groups were tested on their ability to recognize images from the previous day's study session. On the test, some of the visuals were the same as from the day before, some were new additions and some were similar but not the same as the items previously viewed. More members of the caffeine group were able to correctly identify the new images as "similar" to previously viewed images versus erroneously citing them as the same. The team submits that the brain's ability to recognize the difference between two similar but not identical items, called pattern separation, reflects a deeper level of memory retention. Observing that: “Caffeine enhanced performance 24 h after administration,” the study authors: “conclude that caffeine enhanced consolidation of long-term memories in humans.”

Olive Oil May Protect Against Diabetes

Consuming a Mediterranean diet that is rich in extra virgin olive oil may be an effective way to protect people at high-risk for heart disease against diabetes.

Previously, a number of studies have shown that adherence to a Mediterranean diet – rich in olive oil, nuts, as well as fruits, vegetables, and legumes, and limited amounts of dairy products, red meat, soda drinks, processed meats, and sweets – inversely associates with cardiovascular risks.   Jordi Salas-Salvado, from the Hospital de Sant Joan de Reus (Spain), and colleagues studied data collected on 3,541 men and women, ages 55 to 80 years, at high cardiovascular risk but without diabetes at the study’s start.  Subjects were randomly assigned to 1 of 3 diets: a Mediterranean diet supplemented with extra-virgin olive oil; a Mediterranean diet supplemented with nuts; or a control diet (advice on a low-fat diet). No intervention to increase physical activity or lose weight was included.  The researchers observed that those subjects on the Mediterranean diet supplemented with extra-virgin olive oil were the least likely to develop type-2 diabetes, at a 30% reduced likelihood over the next 4 years (as compared to the control diet).   The study authors report that: “A Mediterranean diet enriched with [extra-virgin olive oil] but without energy restrictions reduced diabetes risk among persons with high cardiovascular risk.”

The Avocado Advantage

Adding just one-half of a fresh avocado to a lunch can promote feelings of satiety, among healthy but overweight men and women.

Fresh Hass avocados have 3 grams of total carbohydrate, less than 1 gram of natural sugar per one ounce serving (the least amount of sugar per serving than any other fresh fruit) and contribute 8% of the daily value (DV) for fiber. Each serving of nutrient dense fresh avocado is also a source of naturally good fats. Previously, a number of studies have suggested that avocado consumption may reduce a person's risk factors for heart disease and diabetes, while supporting weight management goals.  Joan Sabate, from Loma Linda University (California, USA), and colleagues asked 26 healthy but overweight adults to incorporate fresh avocado into a lunch – either by replacing other foods or by simply adding it to the meal. The team found that those subjects who added half of a fresh avocado to their lunch reported a significantly decreased desire to eat by 40% over a three-hour period, and by 20% over a five-hour period after the meal, as compared to their desired CE after a standard lunch without avocado. Additionally, the subject reported increased feelings of satisfaction by 26% over the three hours following the meal.  The study authors write that: "The addition of approximately one half of a Hass avocado at a lunch meal can influence post-ingestive satiety over a subsequent 3 and 5 hour period in overweight adults.”

Tree Nuts Reduce Heart Disease & Diabetes Risks

People who consume pistachios, cashews, almonds, pecans and walnuts may be less obese and have fewer risk factors for heart disease and diabetes.

Now known to be a good source of unsaturated (“good”) fat, and high in protein, tree nuts – which include pistachios, cashews, almonds, pecans and walnuts – may help people to manage their weight.  Joan Sabate, from Loma Linda University (California, USA), and colleagues analyzed the dietary habits of 803 adults enrolled in the Adventist Health Study-2.  The data revealed that those subjects who ate about 16 grams (half an ounce) per day – were only slightly over their normal weight, on average, compared to those who ate few or no nuts and were seriously overweight or obese.  As well, those who ate the most nuts had an average body mass index (BMI) of 27, as compared to those who ate the fewest (less than 5 grams daily) at an average BMI of 29-30.  Identifying that one-third of the study subjects had metabolic syndrome, which raises the risks of heart disease and diabetes risk, the team found that every one-ounce serving of tree nuts consumed per week, reduced that risk by 7%.  The study authors submit that: “Tree nuts appear to have strong inverse association with obesity, and favorable though weaker association with [Metabolic Syndrome] independent of demographic, lifestyle and dietary factors.”

The Secret to a Good Night’s Sleep

Variety might be the spice of life, but to what extent does a consistent daily routine serve as a staple for quality sleep?

How important are scheduled activities?  Natalie D. Dautovich, from the University of Alabama (Alabama, USA), and colleagues sought to examine the extent to which a person’s daily routine affects sleep. The team completed an observational study design involving 14 consecutive days of diaries kept by 100 community-dwelling adults. Fifty subjects between the ages of 18 and 30 years, and another 50 subjects between the ages of 60 and 95 years, recorded their patterns of daily activities and sleep. The researchers analyzed 3 activities (going outside, starting work, and eating dinner) and 5 sleep (sleep onset latency, wake time after sleep onset, number of awakenings, total sleep time, and sleep quality rating) variables.   The team found that containing a consistent daily routine associated with better quality sleep. Young adults who went to work and ate dinner at the same time every day typically slept better and wake up fewer times during the night; they also fell asleep more quickly at that time.  Interestingly, the researchers observe that among older adults, inconsistent daily schedules were sometimes linked with better sleep:  older subjects whose dinnertime varied tended to sleep longer at night, and those who started home activities or began work at different times each day fell asleep more quickly.

Dietary Choices May Defeat Diabetes

What foods contain a specific compound that lowers insulin resistance and reduces inflammation?

Flavanoids are a type of antioxidant – compounds shown to be effective in counteracting oxidative damage.  Anthocyanins are a subgroup of flavanoids, for which a number of previous studies suggest beneficial health effects.  Aedin Cassidy, from the University of East Anglia (United Kingdom), and colleagues studied the dietary intake of 1997 women, ages 18 to 76 years, enrolled in the TwinsUK study, and conducted blood tests to assess glucose regulation and inflammation.  The team also calculated insulin resistance, a marker of type-2 diabetes.   Those women who consumed foods abundant in anthocyanins – such as chocolate, tea, and  berries – had lower insulin resistance.  These subjects also were also less likely to suffer chronic inflammation, which can contribute to diabetes, cardiovascular disease, and cancers.

More Fish May Lower Diabetes Risk

Salmon, herring, and sardines are among good sources of omega-3 fatty acids that may help to reduce the risk of Type-2 diabetes.

Type-2 diabetes is becoming increasingly widespread throughout the world.  In that previous studies posit that overweight is a significant risk factor, diet and other lifestyle factors may have potential as interventive approaches to reduce a person’s risk of Type-2 diabetes. Jyrki K. Virtanen, from the University of Eastern Finland (Finland), and colleagues analyzed data collected in the Kuopio Ischaemic Heart Disease Risk Factor Study (KIHD), determining the serum omega-3 fatty acid concentrations of 2,212 men, ages 42 to 60 years age at the onset of the study, in 1984–1989. During a follow-up of 19.3 years, 422 men were diagnosed with type 2 diabetes.  The team found that men in the highest serum omega-3 fatty acid concentration quarter were at 33% lower risk of developing type 2 diabetes, as compared to those men in the lowest quarter.  The study authors report that: “Serum long-chain omega-3 [fatty acid] concentration, an objective biomarker for fish intake, was associated with long-term lower risk of type 2 diabetes.”

Oranges May Help to Protect Vision

Antioxidant-rich foods – including oranges, whole grains, coffee, and tea – may help to lower the risk of cataracts, among aging women.

A cataract is a clouding of the lens in the eye that affects vision. Previous studies have suggested that oxidative damage of the eye's lens, caused by free radicals, may be a critical aspect in the development of cataract. Antioxidant compounds, which are thought to counteract free radical activity, are present in abundant amounts in foods such as oranges, whole grains, coffee, and tea. Susanne Rautiainen, from the Karolinska Institutet (Sweden), and colleagues examined the diets of 30,607 Swedish women, ages 49 to 83 years, enrolled in the Swedish Mammography Cohort study, who were observed for age-related cataract incidence for a mean of 7.7 years. The team utilized the total antioxidant capacity (TAC) value of various foods, as were consumed by the study subjects. The researchers found that the women who ate foods rich in antioxidants experienced a lower risk of cataracts as they age. Specifically, the study authors noted that: "Dietary [total antioxidant capacity] was inversely associated with the risk of age-related cataract."

Vitamin E Slows Functional Decline

One of the largest and longest-treatment trials involving Alzheimer’s patients supports the utility and efficacy of alpha-tocopherol to slow functional decline.

A major burden in Alzheimer's Disease is the potential loss of the ability to complete the activities of daily living, and thus to live independently.  Maurice Dysken, from the Minneapolis VA Health Care System (Minnesota, USA), and colleagues enrolled 613 patients with mild to moderate Alzheimer' Disease and randomly assigned each to one of four groups: the first group received 2,000 IU per day of vitamin E (as alpha-tocopherol); the second group received 20 mg per day of an Alzheimer's medication (memantine);  the third group received a combination of vitamin E and memantine; and the fourth group served as placebo. Subjects were followed for an average of 2.5 years. At the end of the study period, the team observed a clinically significant delay in functional decline of 6.2 months in the vitamin E group, compared with placebo. No benefits were observed in the drug group or in the combination vitamin-drug group.   Writing that: "Among patients with mild to moderate [Alzheimer's Disease], 2000 IU/d of alpha tocopherol … resulted in slower functional decline,” the study authors submit that their data “suggest[s] benefit of alpha tocopherol in mild to moderate [Alzheimer's Disease] by slowing functional decline and decreasing caregiver burden.”

Vitamin E Supplementation Linked to Better Functional Outcomes in Alzheimer's Patients

Vitamin E supplementation is associated with slower functional decline among patients with mild-to-moderate Alzheimer disease, according to a JAMA study.

Over 600 Veterans Affairs patients with mild-to-moderate Alzheimer's who were taking an acetylcholinesterase inhibitor were randomized to receive synthetic vitamin E (2000 IU/day) plus placebo, memantine plus placebo, vitamin E plus memantine, or double placebo.

After a mean follow-up of roughly 2 years, patients assigned to vitamin E alone had better scores on their ability to perform activities of daily living, translating to a 6-month delay in disease progression, compared with patients given placebo. Patients taking memantine — either alone or with vitamin E — did not see a similar benefit. Neither treatment was associated with increased risk for adverse events, including all-cause mortality.

Editorialists stress the importance of not extrapolating the current findings to the "use of vitamin E at different dosages, among people with different [Alzheimer's] severity levels, or in combination with different agents."

“E”asy Way to Reduce Bone Fracture Risk

Dietary supplementation of Vitamin E as alpha-tocopherol may reduce the risk of bone fractures, among aging men and women.

An effective antioxidant, Vitamin E  is thought to exert  positive effects on both bone and muscle mass.  Karl Michaelsson, from Uppsala University (Sweden), and colleagues studied data collected on 14,738 women, followed for 19 years, and found that those subjects with the lowest consumption of alpha-tocopherol were at an 86% increased risk of hip fracture; and those who consumed a dietary supplement containing alpha-tocopherol were at 22% reduced risk of hip fracture.  Among 1,138 men studied, low levels of alpha-tocopherol more than tripled the rate of hip fracture.  The study authors write that: “Low intakes and low serum concentrations of [alpha]-tocopherol are associated with an increased rate of fracture in elderly women and men.”

Higher Magnesium Intake May Lower Diabetes Risk

 (HealthDay News) – Higher magnesium intake may lower risk of incident diabetes, particularly among those at highest risk, according to a study published online Oct. 2 in Diabetes Care.

Based on magnesium intake, Adela Hruby, PhD, from Tufts University in Boston, and colleagues assessed the risk of incident "metabolic impairment," defined as impaired fasting glucose (≥5.6 to <7mmol/L), impaired glucose tolerance (two-hour post-load glucose, ≥7.8 to <11.1mmol/L), insulin resistance (IR), or hyperinsulinemia (≥90th percentile of homeostasis model assessment of IR or fasting insulin, respectively). Study participants included 2,582 community-dwelling individuals aged 26–81 years old.

The researchers found that those with the highest magnesium intake had a 37% lower risk of incident metabolic impairment (Ptrend=0.02) compared to those with the lowest magnesium intake. In those with baseline metabolic impairment, higher intake was associated with a 32% lower risk of incident diabetes (Ptrend=0.05). In the combined population, the risk for those with the highest intake was 53% (Ptrend=0.0004) of those with the lowest intake. The association in the normal population was attenuated with adjustments for risk factors and dietary fiber while the association was not substantially affected in the metabolically impaired. Higher magnesium intake was linked to lower long-term changes in fasting glucose and IR, but no significant trends were observed in fasting insulin, post-load values, or insulin sensitivity.

"Magnesium intake may be particularly beneficial in offsetting risk of developing diabetes among those at high risk," the authors write.

 (HealthDay News) – Exposure to sunlight causes arterial vasodilation and lowers blood pressure (BP), according to research published online Jan. 20 in the Journal of Investigative Dermatology.

Donald Liu, MB, ChB, PhD, of the University of Edinburgh in the United Kingdom, and colleagues exposed the skin on the forearms of 24 participants to ultraviolet A (UVA) wavelengths of sunlight to investigate the effects of UVA on nitric oxide (NO) availability and the resulting cardiovascular effects.

The researchers found that exposure to UVA lowered BP, with concomitant decreases in circulating nitrate and increases in nitrite concentrations. Because dietary intervention to modify the availability of systemic nitrate did not affect these UV-induced hemodynamic changes, it appears that they are not mediated by the direct utilization of circulating nitrate. UVA irradiation of the forearm increased blood flow independently of NO-synthase activity, indicating that pre-formed cutaneous NO stores were involved. Studies with confocal fluorescence microscopy revealed that UVA irradiation causes NO-synthase-independent, dose-dependent release of NO. The majority of light-sensitive NO was pooled in the upper epidermis.

"Collectively, our data provide mechanistic insights into an important function of the skin in modulating systemic NO bioavailability which may account for the latitudinal and seasonal variations of BP and cardiovascular disease," the authors write.

Association of increased serum glycated albumin levels with low coronary collateralization in type 2 diabetic patients with stable angina and chronic total occlusion Full Text 
Cardiovascular Diabetology, 01/19/2014  Clinical Article

Shen Y, et al. – The authors investigated whether serum glycated albumin (GA) levels are related to coronary collateralization in type 2 diabetic patients with chronic total occlusion. Increased GA levels in serum are associated with impaired collateral growth in type 2 diabetic patients with stable angina and chronic total occlusion.

Abstract

BACKGROUND:

We investigated whether serum glycated albumin (GA) levels are related to coronary collateralization in type 2 diabetic patients with chronic total occlusion.

METHODS:

Blood levels of GA and glycosylated hemoglobin (HbA1c) were determined in 317 diabetic and 117 non-diabetic patients with stable angina and angiographic total occlusion of at least one major coronary artery. The degree of collaterals supplying the distal aspect of a total occlusion from the contra-lateral vessel was graded as low (Rentrop score of 0 or 1) or high collateralization (Rentrop score of 2 or 3).

RESULTS:

For diabetic patients, GA (21.2 ± 6.5% vs. 18.7 ± 5.6%, P < 0.001) but not HbA1c levels (7.0 ± 1.1% vs. 6.8 ± 1.3%, P = 0.27) was significantly elevated in low collateralization than in high collateralization group, and correlated inversely with Rentrop score (Spearmen's r = -0.28, P < 0.001; Spearmen's r = -0.10, P = 0.09, respectively). There was a trend towards a larger area under the curve of GA compared with that of HbA1c for detecting the presence of low collateralization (0.64 vs. 0.58, P = 0.15). In non-diabetic patients, both GA and HbA1c levels did not significantly differ regardless the status of coronary collateralization. In multivariable analysis, female gender, age > 65 years, smoke, non-hypertension, duration of diabetes > 10 years, metabolic syndrome, eGFR < 90 ml/min/1.73 m2, and GA > 18.3% were independently determinants for low collateralization in diabetic patients.

CONCLUSIONS:

Increased GA levels in serum are associated with impaired collateral growth in type 2 diabetic patients with stable angina and chronic total occlusion.

 

Low resting heart rate associated with decreased all-cause mortality

As reported in Mayo Clinic Proceedings, a resting heart rate < 60 bpm is associated with increased cardiorespiratory fitness and decreased all-cause mortality, while a resting heart rate ≥ 80 bpm was associated with decreased cardiorespiratory fitness and increased all-cause mortality. The study involved 53322 patients with cardiovascular disease or cancer.

Saxena A, et al. – The aim is to study the protective role of lower resting heart rate (RHR) in cardiovascular disease (CVD) and all–cause mortality. Lower cardiorespiratory fitness levels and higher RHRs are linked to greater CVD and all–cause mortality.

Methods

  • Patients (n=53,322) who received a baseline medical examination between January 1, 1974, and December 31, 2002, were recruited from the Cooper Clinic, Dallas, Texas.
  • They completed a medical questionnaire and underwent clinical evaluation.
  • Patients with CVD or cancer or who had less than 1 year of mortality follow–up were excluded from the study.
  • Relative risks and 95% CIs for all–cause and CVD mortality across RHR categories were estimated using Cox proportional hazards models.

Results

  • Highest cardiorespiratory fitness with lower mortality was found in individuals with an RHR of less than 60 beats/min.
  • Similarly, patients with a higher RHR (>=80 beats/min) were at greater risk for CVD and all–cause mortality compared with an RHR of less than 60 beats/min.
  • This analysis was followed by stratification of the data by hypertension, where hypertensive individuals with high RHRs (>=80 beats/min) were found to be at greater risk for CVD and all–cause mortality compared with those with hypertension and lower RHRs (<60 beats/min).
  • In addition, unfit individuals with high RHRs had the greatest risk of CVD and all–cause mortality.
  • The unfit with low RHR group had a similar risk for CVD and all–cause mortality as the fit with high RHR group.

Five-Day Prednisone Therapy Should Be the Norm for Treating COPD Exacerbations

A Swiss study provides the final piece of evidence that short-course steroids are equivalent to longer courses.

Treatment for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) includes inhaled bronchodilators, antibiotics, and systemic glucocorticoids. In a 1999 randomized trial, 2-week courses of glucocorticoids (methylprednisolone for 72 hours, followed by tapered oral prednisone) were as effective as 8-week courses and more effective than placebo (NEJM JW Gen Med Jul 2 1999). Subsequently, shorter-course and lower-dose glucocorticoid therapies were shown to be effective as well, but the optimal dosage and length of treatment still were debated. A 2011 Cochrane review showed no excess of treatment failures with regimens of ≤7 days versus >7 days, but data were insufficient to draw firm conclusions. The 2013 GOLD guidelines recommended prednisolone (30–40 mg for 10–14 days), citing level D evidence.

In a 2013 Swiss trial, 314 patients with COPD exacerbations — most of whom were hospitalized — were randomized to 5 days or 14 days of prednisone (40 mg) in addition to other standard therapies. These patients had GOLD stage 3–4 COPD with an average forced expiratory volume in 1 second (FEV1) of 31% of predicted. About 10% of patients required home oxygen, and 30% were taking systemic steroids prior to the study. No difference between groups was noted in the primary endpoint (time to exacerbation within 180 days). Lung function, mortality, need for mechanical ventilation, and symptoms scores all were similar between groups; adverse events, including hyperglycemia or hypertension, were rare and occurred equally in both groups. Hospital stays averaged 1 day shorter with the 5-day regimen (NEJM JW Gen Med Jun 24 2013).

Patients with COPD exacerbations now should be treated with 40-mg prednisone for 5 days. Patients in the latest study had severe-to–very severe disease, so this short-course approach should be applicable to all patients. Because patients often experience several exacerbations annually, this approach could lower overall steroid exposure dramatically.

 

Comparison of the effects of amlodipine and losartan on blood pressure and diurnal variation in hypertensive stroke patients: a prospective, randomized, double-blind, comparative parallel study 
Clinical Therapeutics, 12/28/2013 
 Clinical Article

Kwon HM, et al. – This study was conducted to compare the BP–lowering and diurnal BP variation effects of amlodipine and losartan on acute stroke patients. The noninferiority of amlodipine was not confirmed by the per–protocol analysis. However, amlodipine showed a favorable effect on the morning surge.

Methods

  • Seventy–seven hypertensive patients with acute stroke were enrolled in this randomized, double–blind, single–center clinical trial.
  • They were randomly assigned to receive either amlodipine or losartan daily.
  • To evaluate whether amlodipine was noninferior to losartan, ambulatory BP monitoring was performed before the drugs were first administered and at the end of week 8.
  • BP variables analyzed included the mean awake, sleep, morning, evening, and prewake BP values; the nocturnal dipping status; and the morning surge.

Results

  • Thirty–nine patients in the amlodipine group and 38 patients in the losartan group completed the follow–up.
  • In the baseline characteristics, mean age was 63.6 years, and 68.8% were male.
  • In the intention–to–treat analysis, the mean (SD) systolic BP decreased 14.82 (11.71) mm Hg in the amlodipine group and 13.11 (12.69) mm Hg in the losartan group, and amlodipine proved noninferior to losartan (mean difference, 1.71 mm Hg [95% CI, –3.83 to 7.26]).
  • However, in the per–protocol analysis, noninferiority was not proven (BP reduction, 16.06 [11.33] vs 17.17 [11.85] mm Hg; mean difference, –1.11 mm Hg [95% CI, –6.88 to 4.65]).
  • Amlodipine had a greater tendency than losartan to produce a blunt morning surge.

Telomere Length Prognostic for 50 to 75 Year-Old Men With ACS

 (HealthDay News) — For men aged 50–75 years with acute coronary syndrome, shorttelomeres are independently associated with worse prognosis, according to a study published in the February 1 issue of The American Journal of Cardiology.

Jose-Angel Perez-Rivera, MD, from the University Hospital of Salamanca in Spain, and colleagues assessed the prognostic value of telomere length, measured by quantitative polymerase chain reaction in peripheral blood leukocytes of 203 men admitted with acute coronary syndrome. The men were classified into two groups according to age: 50–75 years, and >75 years. Patients underwent more than 600 days of clinical follow-up and a prognostic combined event was defined.

The researchers found that for men aged 50–75 years, those with short telomeres had significantly worse prognosis (P<0.05), but this association was not seen for men aged older than 75 years (P =0.91). For men aged 50–75 years, Cox analysis confirmed short telomeres as an independent prognostic risk factor.

"In conclusion, telomere length is a good predictor of cardiovascular prognosis in men admitted for acute coronary syndrome, but this relation depends on the chronological age of the population studied," the authors write.

BMI Thresholds Predict Metabolic Syndrome in Teens

 (HealthDay News) — The US Centers for Disease Control and Prevention and FITNESSGRAM (FGram) body mass index (BMI) thresholds are predictive of metabolic syndrome in U.S. adolescents, according to a study published online January 27 in Pediatrics.

Kelly R. Laurson, PhD, from Illinois State University in Normal, and colleagues analyzed data from 3,385 adolescents participating in the National Health and Nutrition Examination Surveywho were measured for anthropometric variables and metabolic risk factors. Weight status was categorized using CDC and FGram thresholds.

The researchers found that the prevalence of metabolic syndrome was <2 percent in the normal-weight groups and ranged from 19–33% in obese youth, with odds of metabolic syndrome 46–67% and 19–22 times higher for obese boys and girls, respectively, versus normal-weight youth. Based on receiver operating characteristic analyses, the optimal thresholds were similar to the CDC standards and the FGram standards, for boys and girls, respectively. The association between BMI thresholds and metabolic syndrome was stronger in boys than in girls.

"Both the CDC and FGram standards are predictive of metabolic syndrome. The diagnostic utility of the CDC thresholds outperformed the FGram values for boys, whereas FGram standards were slightly better thresholds for girls," the authors conclude. "The use of a common set of thresholds for school and clinical applications would provide advantages for public health and clinical research and practice."

One author serves as the Scientific Director and oversees the activities of the Scientific Advisory Board of the FITNESSGRAM program.

Markers Other Than HbA1c Useful for Monitoring Diabetes

 (HealthDay News) – Fructosamine and glycated albumin are markers of glycemic control that may complement hemoglobin A1c (HbA1c) in identifying risk of diabetes and its complications, according to research published online Jan. 15 in The Lancet Diabetes & Endocrinology.

Elizabeth Selvin, PhD, MPH, of the Johns Hopkins University Bloomberg School of Public Health in Baltimore, and colleagues measured levels of fructosamine and glycated albumin in 11,348 adults without diabetes and 958 with diagnosed diabetes. The authors sought to assess their value in predicting risk of incident diabetes and its complications during two decades of follow-up.

The researchers found that, similar to HbA1c, fructosamine and glycated albumin were strongly associated with retinopathy. Compared with individuals with no diabetes and marker levels less than the 75th percentile, patients with fructosamine and glycated albumin levels greater than the 95th percentile had significantly higher risk for chronic kidney disease (multivariable-adjusted hazard ratios (HRs), 1.5 and 1.48, respectively) and incident diabetes (HRs, 4.96 and 6.17, respectively). Prediction of incident diabetes was strongest for HbA1c (C-statistic, 0.76) compared with fructosamine (C-statistic, 0.706) and glycated albumin (C-statistic, 0.703). Prediction of incident chronic kidney disease was almost as strong for fructosamine and glycated albumin (C-statistic for both, 0.717) as for HbA1c (C-statistic, 0.726).

"Fructosamine and glycated albumin were strongly associated with diabetes and its microvascular complications and complemented the prognostic utility of HbA1c," the authors write.

Mediterranean Diet Lowers Risk of Peripheral Artery Disease

 (HealthDay News) – A Mediterranean diet supplemented with extra-virgin olive oil or nuts is associated with a lower risk of peripheral artery disease (PAD), according to a research letter published in the Jan. 22/29 issue of the Journal of the American Medical Association.

Miguel Ruiz-Canela, PhD, from the University of Navarra in Pamplona, Spain, and colleagues conducted a multicenter, randomized, primary prevention feeding trial between October 2003 and December 2010. Eligible participants (men aged 55–80 years and women aged 60–80 years, without clinical PAD or baseline cardiovascular disease, but with type 2 diabetes or ≥3 cardiovascular risk factors) were randomized to either Mediterranean diet supplemented with extra-virgin olive oil; Mediterranean diet supplemented with nuts; or low-fat diet counseling (control group).

The researchers found that both Mediterranean diet interventions correlated with reduced risk for PAD compared with the control group, with hazard ratios of 0.34 for the Mediterranean diet plus extra-virgin olive oil and 0.50 for the Mediterranean diet plus nuts, after adjustment for classic atherosclerotic risk factors. There was no significant difference between the active intervention groups (hazard ratio, 0.71; 95% confidence interval, 0.38–1.33). To prevent one case of PAD per year, the number needed to treat was 336 for the Mediterranean diet plus extra-virgin olive oil and 448 for the Mediterranean diet plus nuts group.

"To our knowledge, this is the first randomized primary prevention trial to suggest an association between a dietary intervention and PAD," the authors write. "These results are consistent with previous observational studies and relevant from a public health perspective."

Two authors disclosed financial ties to the International Nut Council. Supplemental foods used in the study were donated by Patrimonio Comunal Olivarero and Hojiblanca, the California Walnut Commission, Borges SA, and La Morella Nuts.

 

Cure for Baldness on the Horizon?

 (HealthDay News) — Scientists might be able to offer "hair-challenged" males a new glimmer of hope when it comes to reversing baldness, according to a study published online January 28 inNature Communications.

Xiaowei Xu, MD, from the Perelman School of Medicine at the University of Pennsylvania in Philadelphia, and colleagues say they've gotten closer to being able to use stem cells to treat thinning hair – at least in mice. In the new study, Xu's team converted induced pluripotent stem cells (iPSCs) – reprogrammed adult stem cells with many of the characteristics of embryonic stem cells – into epithelial stem cells.

The epithelial stem cells were mixed with certain other cells and implanted into mice. They produced the outermost layers of skin cells and follicles that are similar to human hair follicles. This suggests that these cells might eventually help regenerate hair in people, the researchers said.

"This is the first time anyone has made scalable amounts of epithelial stem cells that are capable of generating the epithelial component of hair follicles," Xu said in a university news release.

Obesity Related to High BPA Levels in Teens

 (HealthDay News) – Increased urinary phthalates are associated with increased insulin resistance in adolescents; and higher bisphenol A (BPA) levels are associated with obesity and abnormal waist circumference-to-height ratio in children, according to two studies published online Aug. 19 in Pediatrics.

Leonardo Trasande, MD, MPP, from New York University in New York City, and colleagues used cross-sectional-data from 766 fasting youth (aged 12–19 years) from the National Health and Nutrition Examination Survey (NHANES) 2003–2008 to examine the correlations of phthalate metabolites with measures of homeostatic model assessment of insulin resistance (HOMA-IR). The researchers found that after adjustment for confounding variables there was a 0.27 increase in HOMA-IR with each log increase in di-2-ethylhexylphthalate metabolites. The correlation persisted even after controlling for BPA.

Donna S. Eng, MD, from the University of Michigan in Ann Arbor, and colleagues used NHANES 2003–2008 data to examine the correlation between urinary BPA levels and measures of adiposity, cholesterol, insulin, and glucose among 6- to 18-year-olds. The researchers found that the odds of obesity were higher with increasing quartiles of BPA (quartiles 2, 3, and 4 vs. 1 odds ratios, 1.74, 1.64, and 2.01, respectively). The odds of an abnormal waist circumference-to-height ratio were also increased (quartiles 2, 3, and 4 vs. 1 odds ratios, 1.37, 1.41, and 1 55, respectively). There were no significant associations between BPA and other chronic disease risk factors.

"Longitudinal analyses are needed to elucidate temporal relationships between BPA exposure and the development of obesity and chronic disease risk factors in children," Eng and colleagues conclude.

DIY Cognitive Screening

A self-administered test can help spot early symptoms of cognitive issues.

Researchers at The Ohio State Universityt (Ohio, USA) have developed a do-it-yourself test that can help doctors spot early symptoms of cognitive issues in their patients. The Self-Administered Gerocognitive Examination (SAGE test) can also be taken at home by patients, who can then share the results with their physicians to promote early disease detection.  Taking less than 15 minutes to complete, Douglas Scharre and colleagues posit that the SAGE test enables doctors to get a baseline of cognitive function in their patients, so they can be followed for a later onset of Alzheimer’s Disease.  As well, the team suggests that the SAGE test could also provide health care providers and caregivers an earlier indication of life-changing events that could lie ahead. Earlier research by Scharre found that four out of five people (80%) with mild thinking and memory (cognitive) issues will be detected by this test, and 95% of people without issues will have normal SAGE scores. Observing that: “From … 1,047 individuals over age 50 screened with SAGE …cognitive impairment was identified in 28%,” the study authors submit that: “Community cognitive screening using SAGE was found to be feasible and efficient in diverse settings with both small and large groups.”

Enduring Effect of Cognitive Training in Older Adults

Benefits persisted at 10 years in a randomized trial.

 Wayne PM et al., J Am Geriatr Soc 2014 Jan 62:25

The ACTIVE study was initiated in 1998 to determine whether cognitive training could improve outcomes in 2800 older adults without significant cognitive deficits at baseline. Participants (age, >65; mean age, 74) were randomized to undergo memory training, reasoning training, speed-of-processing training, or no intervention. Training consisted of 10 hour-long small-group training sessions during a 5- to 6-week period following randomization; participants were reassessed periodically during 10 years of follow-up. At 10 years, those who underwent reasoning and speed-of-processing training had persistent, statistically significant, small-to-moderate improvements in their respective domains compared with controls; in contrast, those in the memory-training group experienced no long-term improvement in memory. All three treatment groups reported significantly less difficulty with activities of daily living than did the control group.

Tai chi, a so-called mind-body activity, is another increasingly popular approach to address both physical and cognitive decline in older adults. Researchers conducted a meta-analysis of 11 randomized trials of tai chi in which cognition was assessed and found that tai chi (compared with control interventions or no intervention) improved cognition moderately in both normal and impaired older adults. Duration of these studies was generally short (≤1 year).

 

High (and Low?) Endogenous Estradiol Linked to Increased Dementia Risk in Postmenopausal Women

High levels of endogenous estradiol are associated with increased risk for incident dementia among postmenopausal women, especially among those who have diabetes, a Neurology study finds.

Using data from a French prospective cohort, researchers identified some 130 postmenopausal women who developed dementia and 540 who remained dementia-free over a 4-year period. Endogenous estradiol was measured at baseline. None were using hormone therapy.

After multivariable adjustment, researchers found a J-shaped association between estradiol and dementia: Compared with women with moderate estradiol levels, those with the highest levels had a 2.4-fold risk for dementia, and those with the lowest levels had a 2.2-fold risk. In an analysis stratified according to diabetes status, diabetic women with high estradiol had a 14-fold increase in dementia risk.

The researchers attribute the increased risk at low estradiol levels to possible reverse causation. Regarding the link between high estradiol and dementia in diabetic women, they write: "It is plausible that higher endogenous [estradiol] together with diabetes promote a set of unfavorable vascular processes to increase risk of dementia in postmenopausal women."

Three Reasons to Take A Stand

Why is prolonged sitting bad for your health?

By opting to stand, instead of sitting for an extended period of time, and increasing physical activity throughout the day, we can improve health and quality of life while reducing the risks for chronic diseases such as cardiovascular disease, diabetes, heart disease, stroke, breast cancer and colon cancer, among others.  Richard R. Rosenkranz, from Kansas State University (Kansas, USA), and colleagues studied data collected on 194,545 men and women, ages 45 to 106, who were enrolled in Australia’s 45 and Up Study.  Positing that prolonged sitting reduces muscle contractions and shuts off the activity of lipoprotein lipase (LPL), which helps to process fat into energy, these study authors write that their data adds to the evidence to support efforts “to increase [physical activity] and decrease sitting time toward the achievement of better population health and the pursuit of successful aging. “  Among postmenopausal women, Rebecca Seguin, from Cornell University (New York, USA), and colleagues found that those with the highest amounts of sedentary time – defined as sitting and resting, excluding sleeping – died earlier than their most active peers. Further, the researchers found that women with more than 11 hours of daily sedentary time faced a 12% increase in all-cause premature mortality, as compared with the most energetic group – those with four hours or less of inactivity. The sedentary group also upped their odds for death due to cardiovascular disease, coronary heart disease and cancer by 13, 27 and 21%, respectively.  Importantly, the team also observed that excess sedentary time tends to make it harder to regain physical strength and function.  These study authors warn that: “There [is] a linear relationship between greater amounts of sedentary time and mortality risk.”  Among men, sitting for long periods increases heart failure risk in men – even for those who exercise regularly. Deborah Rohm Young, from Kaiser Permanante (California, USA), and colleagues followed a racially diverse group of 84,170 men, ages 45 to 69 years, without heart failure. Exercise levels were calculated in METs (metabolic equivalent of task), a measure of the body's energy use. Sedentary levels were measured in hours. After an average of nearly eight years of follow-up, researchers found that those men with low levels of physical activity were 52% more likely to develop heart failure than men with high physical activity levels, even after adjusting for differences in sedentary time. Further, outside of work, men who spent five or more hours a day sitting were 34%  more likely to develop heart failure than men who spent no more than two hours a day sitting, regardless of how much they exercised. The team also reveraled that heart failure risk more than doubled in men who sat for at least five hours a day and got little exercise, as compared to men who were very physically active and sat for two hours or less a day. These authors urge that: “Both physical activity and sedentary time may be appropriate intervention targets for preventing [heart failure].”

Assessing the Clinical Benefits of Lipid-Disorder Drugs

Dietary Fiber Intake Is Associated Inversely with Cardiovascular Risks

Threapleton DE et al., BMJ 2013 Dec 20; 347:f6879

Every 7-g increase in daily dietary fiber intake was associated with significantly lower risks for coronary heart disease and CV disease.

High dietary fiber intake is associated with lower risk for coronary heart disease (CHD). However, which fiber types are protective and whether a dose–response relation exists are unclear. In this meta-analysis of 22 observational cohort studies, investigators assessed associations between intakes of various dietary fiber types and risks for first CHD and cardiovascular disease (CVD) events.

Every 7-g daily increase in total dietary fiber intake (e.g., the amount in about 1 cup of bran flakes, 1 cup of raw green peas, or 2 apples) was associated significantly with lower risk for CHD and CVD events (risk ratio, 0.9 for both). Findings were similar for each of the various types of fiber (soluble, insoluble, vegetable, fruit, cereal), although the lowered risk just missed statistical significance for some subgroups.

COMMENT

In this study, higher dietary fiber intakes — from various sources — were associated with lower risks for coronary heart disease and cardiovascular disease in a dose–response pattern. Women and men should aim for total dietary fiber intakes of 25 g daily and 38 g daily, respectively. Finally, although these observational studies adjusted for confounding variables to some extent, some confounding remains possible (e.g., high dietary fiber intake is associated with other healthy behaviors).

β-Blockers Are Beneficial and Safe in Patients with COPD

Quint JK et al., BMJ 2013 Nov 22; 347:f6650

Among patients with chronic obstructive pulmonary disease and myocardial infarctions, these drugs improved 3-year survival.

Evidence suggests that β-blockers are safe and beneficial, yet underused, in patients with chronic obstructive pulmonary disease (COPD). To examine whether β-blockers are associated with longer survival in COPD patients with first myocardial infarctions (MIs), U.K. investigators conducted this retrospective population-based cohort study of 1069 patients. Median follow-up after MI was 2.9 years.

Twenty-three percent of patients were taking β-blockers before hospitalization for MI, 22% received β-blocker prescriptions during hospitalization, and 55% never received prescriptions for β-blockers. Most of the prescribed β-blockers (83%) were cardioselective; most patients tolerated β-blockers well. After adjustment for multiple factors, patients who took β-blockers before their MIs and patients who received prescriptions for β-blockers during hospitalization were significantly more likely to survive than patients who never received β-blockers (hazard ratios, 0.6 and 0.5, respectively).

COMMENT

Historically, clinicians have avoided prescribing β-blockers for patients with COPD because of concern that these drugs might cause harm (e.g., bronchospasm). The results of this study and others (NEJM JW Gen Med Jun 9 2011) indicate that β-blockers are beneficial and safe in such patients who often have excess risk for myocardial infarction and cardiovascular-related death. However, whether β-blockers (even cardioselective ones) have adverse effects when administered during severe COPD exacerbations remains unclear.

 

Digoxin effect on readmission for heart failure 
In Medicare beneficiaries with systolic heart failure, a discharge prescription of digoxin was associated with lower 30-day all-cause hospital readmission, which was maintained at 12 months, and was not at the expense of higher mortality.

Breast cancer vs heart disease mortality in women 
The clinical implications of the findings of this study are confirmatory and reinforce the importance of promoting women's health during their entire life span, as it may well affect them adversely later in life. The authors highlight the importance of considering age-specific analyses when examining mortality among women. They encourage women to be passionate about coronary heart disease (CHD) awareness, with vigor equal to that of breast cancer awareness, and to talk with their doctors about CHD risk factors, taking action to prevent or control these risk factors when present. The American Journal of Cardiology

Circulating Uric Acid May Play Protective Role in Obesity

 (HealthDay News) — Circulating uric acid affects non-enzymatic antioxidant capacity (NEAC) and markers of oxidative stress in obese subjects, according to a study published online December 18 in Diabetes.

Elisa Fabbrini, MD, PhD, from the Washington University School of Medicine in St. Louis, and colleagues assessed whether alterations in circulating uric acid affect systemic NEAC, markers of systemic and muscle oxidative stress, and whole-body insulin sensitivity using data from obese subjects with high (15 subjects) or normal (16 subjects) serum uric acid. Thirteen of the subjects with high uric acid underwent reduction of serum uric acid to zero by infusion of recombinant urate oxidase and were studied again.

The researchers found that, compared to those with normal uric acid, individuals with high uric acid had 20 to 90% increased NEAC, 40% lower insulin sensitivity, and 30%lower levels of markers of oxidative stress (all P<0.05). Reduction of uric acid resulted in a decrease of 45 to 95% in NEAC and increases of 25–40% in systemic and muscle markers of oxidative stress (all P<0.05), but the reduction had no impact on insulin sensitivity.

"These results demonstrate that circulating uric acid is a major antioxidant, and might help protect against free-radical oxidative damage," the authors write. "However, oxidative stress is not a major determinant of insulin action in vivo."

The study was partially funded by a grant from Sanofi-Aventis.

2013 Heart Failure Guidelines

Background and ObjectiveThis document is a thorough revision of the 2005 ACC/AHA HF guidelines (updated in early 2009). The writers reviewed studies published through October 2011 (with selected additional data published before April 2013).Key RecommendationsClass I recommendations for initial evaluation include: History and physical examination Family history in patients with dilated cardiomyopathy Weight and volume status Complete blood count, urinalysis, electrolytes, lipids, liver panel, and thyroid-stimulating hormone Electrocardiogram Chest radiograph 2-dimensional echocardiogram with assessment of left ventricular (LV) systolic function. Class I recommendations for the use of B-type natriuretic peptide (BNP) or N-terminal pro-BNP include: Assessing the likelihood of HF in ambulatory patients with dyspnea or patients with possible acute decompensated HF when the diagnosis is uncertain Establishing prognosis or disease severity Patients with asymptomatic LV systolic dysfunction (LVSD) should receive an angiotensin-converting enzyme (ACE) inhibitor and a β-blocker to prevent symptomatic HF (Class I).In the absence of contraindications, patients with symptomatic LVSD should receive guideline-directed medical therapy (GDMT) consisting of ACE inhibitor (or angiotensin-receptor blocker), β-blocker, and: Loop diuretics, if needed for volume overload Aldosterone antagonists in patients with symptoms of any severity or following acute myocardial infarction (MI), provided that estimated glomerular filtration rate is >30 mL/min/1.73m2 and potassium levels are <5 mEq/dL. Hydralazine and nitrate combination in black patients with severe symptoms despite other therapy (all Class I). Only those β-blockers proven to improve HF outcomes — long-acting metoprolol, carvedilol, or bisoprolol — should be used in patients with LVSD (Class I).In the absence of contraindications, patients with HF and atrial fibrillation (AF) with an additional risk factor for stroke should receive systemic anticoagulation with warfarin or other approved agents (Class I). The value of anticoagulation in other circumstances is less clear.Agents that are not beneficial or harmful for LVSD include statins (solely for HF), nutritional supplements, hormonal therapies, calcium channel blockers, nonsteroidal anti-inflammatory drugs, thiazolidinediolnes, and long-term infused inotropic drugs (all Class III).Evidence-based approaches to HF patients with preserved systolic function are lacking; recommendations for this group are generic and target coexisting conditions (e.g., hypertension and AF).Recommendations for implantable cardioverter-defibrillator therapy (in many patients with LV ejection fractions <35%) and cardiac resynchronization therapy (CRT; in those with LVSD and QRS prolongation) are consistent with current device-based therapy guidelines (NEJM JW Cardiol Oct 3 2012) and include expanding CRT consideration to patients with New York Heart Association class II symptoms (Class I).Transplantation should be considered in patients with stage D HF that is refractory to GDMT, device, and surgical therapies (Class I).Transitional care at hospital discharge, palliative care, care coordination (all Class I), and participation in quality-improvement initiatives (Class IIa) are encouraged. - See more at: http://www.jwatch.org/na33364/2014/01/28/2013-heart-failure-guidelines?query=etoc_jwgenmed#sthas

USPSTF Issues Draft Recommendations on Abdominal Aortic Aneurysm Screening

The U.S. Preventive Services Task Force now says that the evidence is insufficient to weigh the benefits and harms of screening for abdominal aortic aneurysm (AAA) in women aged 65 to 75 who've ever smoked. The so-called "I statement," published as part of the group's draft recommendation statement on Monday, updates its 2005 guidance, which clearly advised against screening for all women.

As in 2005, the task force continues to recommend:

  • one-time ultrasound screening for AAA in men aged 65 to 75 who've ever smoked (grade B recommendation).
  • selective screening of men in that age group who've never smoked (grade C); never-smokers who might warrant screening include those with a history of vascular aneurysm or a first-degree relative with AAA.
  • no screening for women who've never smoked (grade D).

The recommendations apply to asymptomatic adults aged 50 and older. The draft statement is available for public comment until Feb. 24 at the link below.

Abstract

BACKGROUND:

The relation between body weight and mortality among persons with type 2 diabetes remains unresolved, with some studies suggesting decreased mortality among overweight or obese persons as compared with normal-weight persons (an "obesity paradox").

METHODS:

We studied participants with incident diabetes from the Nurses' Health Study (8970 participants) and Health Professionals Follow-up Study (2457 participants) who were free of cardiovascular disease and cancer at the time of a diagnosis of diabetes. Body weight shortly before diagnosis and height were used to calculate the body-mass index (BMI, the weight in kilograms divided by the square of the height in meters). Multivariable Cox models were used to estimate the hazard ratios and 95% confidence intervals for mortality across BMI categories.

RESULTS:

There were 3083 deaths during a mean period of 15.8 years of follow-up. A J-shaped association was observed across BMI categories (18.5 to 22.4, 22.5 to 24.9 [reference], 25.0 to 27.4, 27.5 to 29.9, 30.0 to 34.9, and ≥35.0) for all-cause mortality (hazard ratio, 1.29 [95% confidence interval {CI}, 1.05 to 1.59]; 1.00; 1.12 [95% CI, 0.98 to 1.29]; 1.09 [95% CI, 0.94 to 1.26]; 1.24 [95% CI, 1.08 to 1.42]; and 1.33 [95% CI, 1.14 to 1.55], respectively). This relationship was linear among participants who had never smoked (hazard ratios across BMI categories: 1.12, 1.00, 1.16, 1.21, 1.36, and 1.56, respectively) but was nonlinear among participants who had ever smoked (hazard ratios across BMI categories: 1.32, 1.00, 1.09, 1.04, 1.14, and 1.21) (P=0.04 for interaction). A direct linear trend was observed among participants younger than 65 years of age at the time of a diabetes diagnosis but not among those 65 years of age or older at the time of diagnosis (P<0.001 for interaction).

CONCLUSIONS:

We observed a J-shaped association between BMI and mortality among all participants and among those who had ever smoked and a direct linear relationship among those who had never smoked. We found no evidence of lower mortality among patients with diabetes who were overweight or obese at diagnosis, as compared with their normal-weight counterparts, or of an obesity paradox.

Modeling Study: Similar Effects for Statin or Apple a Day

 (HealthDay News) – An apple a day or a statin a day are equally likely to keep the doctor away, according to a modeling study published online Dec. 17 in BMJ.

Adam D.M. Briggs, from University of Oxford in the United Kingdom, and colleagues modeled the effect on vascular mortality if all adults in the United Kingdom over age 50 years were prescribed a statin (for those not already taking one) or an apple a day for everyone, regardless of whether they were taking a statin or not. Compliance of 70% was estimated.

The researchers found that for a statin a day the estimated annual reduction in mortality from vascular disease was 12% per 1mmol/L reduction in low-density lipoprotein cholesterol, or 9,400 deaths. Using a PRIME model (assuming an apple weighs 100g and that overall calorie consumption remains constant) the equivalent reduction from an apple a day was found to be 8,500.

"With similar reductions in mortality, a 150 year old health promotion message is able to match modern medicine and is likely to have fewer side effects," the authors conclude.

Low Vitamin B12 Linked to Postural Orthostatic Tachycardia

 (HealthDay News) – During adolescence, low vitamin B12 levelsare associated with postural orthostatic tachycardia syndrome (POTS), according to a study published online Dec. 23 inPediatrics.

Taliha Öner, MD, from Dr. Behçet Uz Children's Hospital in Izmir, Turkey, and colleagues examined the correlation between vitamin B12 levels and POTS during adolescence. Serum vitamin B12, folic acid, and ferritin levels were assessed in 125 patients (mean age, 11.1 years; 60% female) reporting short-term loss of consciousness and diagnosed with vasovagal syncope, and 50 control subjects (mean age, 10.94 years; 62% female).

The researchers found that patients had significantly lower levels of vitamin B12 vs. controls (352.75 vs. 411.32pg/mL; P<0.001), and that a low vitamin B12 level was significantly more prevalent in the patient vs. the control group (47.2 vs. 18%; P<0.001). Within the patient group, vitamin B12 levels were significantly lower in children with the POTS pattern than those without the POTS response (P=0.03).

"Our study shows the association between the etiopathogenesis of POTS and the vitamin B12deficiency-induced sympathetic nervous system-baroreceptor dysfunction," the authors write.

Atrial Ectopy Is Associated with Incident Atrial Fibrillation

Jamaluddin Moloo, MD, MPH Reviewing Dewland TA et al., Ann Intern Med 2013 Dec 3; 159:721

In a prospective study, incorporating premature atrial contraction counts improved AF risk prediction.

Studies have shown that premature atrial contractions (PACs) can initiate atrial fibrillation (AF) and that PACs are associated with incident AF. To evaluate further the contribution of PACs to prediction of risk for AF, researchers investigated the PAC count in 1260 older adults (mean age, 71) without AF who were enrolled in a multicenter, prospective, U.S. cardiovascular study. Participants underwent 24-hour Holter monitoring at baseline and were followed for incident AF with annual electrocardiograms and by hospital-discharge data.

During median follow-up of 13 years, 27% of participants developed AF. The median hourly PAC count at baseline was significantly higher among those with incident AF than among those who did not develop AF (5.3 vs. 1.8 beats/hour); adjusted hazard ratio for incident AF was 4.92 among those in the highest versus the lowest quartiles of hourly PAC frequency. Addition of PAC frequency to the Framingham AF risk model significantly improved 10-year AF risk discrimination.

COMMENT

This study showed an association between higher premature atrial contraction counts and incident atrial fibrillation. The finding adds to our understanding of AF, but it will not be clinically useful until we develop interventions that use PAC counts to safely and effectively lower the incidence of AF.

 

Diuretics and Statins Are Associated with New-Onset Diabetes

Paul S. Mueller, MD, MPH, FACP Reviewing Shen L et al., BMJ 2013 Dec 9; 347:f6745

These drugs — but not β-blockers or calcium-channel blockers — were associated with new-onset diabetes in patients with impaired glucose tolerance.

Evidence suggests that β-blocker, diuretic, or statin use increases risk for new-onset diabetes. In this reanalysis of the randomized, controlled NAVIGATOR trial (NEJM JW Cardiol Mar 14 2010) data, investigators assessed whether β-blocker, thiazide diuretic, statin, or calcium-channel blocker (CCB) use in >9300 patients with impaired glucose tolerance and cardiovascular risk factors was associated with new-onset diabetes.

During a median follow-up of 5 years, β-blockers, thiazide diuretics, statins, and CCBs were each started in about 20% of patients who had not been exposed to these drugs previously. After adjustment for multiple variables, risk for new-onset diabetes was significantly higher in patients who initiated diuretics (hazard ratio, 1.2) or statins (HR, 1.5) than in patients who were not treated with diuretics or statins, respectively. The number needed to harm for diuretics was 17 and for statins was 12. Risk for new-onset diabetes did not change among patients who initiated β-blockers or CCBs


Warfarin Initiation Negatively Linked to Stroke in A-Fib Patients

(HealthDay News) – Patients with atrial fibrillation are at higher risk of having a stroke in the first month after initiating treatment with the anti-clotting drug warfarin, according to a study published online Dec. 18 in European Heart Journal.

Noting that previous studies have observed a link between warfarin treatment and stroke among patients with atrial fibrillation, Laurent Azoulay, PhD, from McGill University in Montreal, and colleagues analyzed data on stroke incidence in 70,766 adults newly diagnosed with atrial fibrillation. Each case of incident stroke was randomly matched with 10 controls.

During 275,987 person-years of follow-up, the researchers found that 5,519 patients had a stroke. After adjusting for various factors, compared with no use of any antithrombotic therapy for at least one year, the risk of stroke was significantly higher within 30 days of initiating warfarin treatment (relative risk, 1.71). The risk of stroke was lower when warfarin treatment was initiated more than 30 days earlier (relative risks: 0.50 for 31–90 days earlier and 0.55 for >90 days earlier).

"Patients initiating warfarin may be at an increased risk of stroke during the first 30 days of treatment, supporting the biological plausibility of a transient hypercoagulable state at the start of the treatment, although additional studies are needed to confirm these findings," Azoulay and colleagues conclude.

The study was funded by Bristol-Myers Squibb and Pfizer. More than one author disclosed financial ties to pharmaceutical companies, including Bristol-Myers Squibb.

Atrial fibrillation and the risk of myocardial infarction 
JAMA Internal Medicine, 01/08/2014 
 Evidence Based Medicine  Clinical Article

Soliman EZ, et al. – Myocardial infarction (MI) is an established risk factor for atrial fibrillation (AF). However, the extent to which AF is a risk factor for MI has not been investigated. To examine the risk of incident MI associated with AF. AF is independently associated with an increased risk of incident MI, especially in women and blacks. These findings add to the growing concerns of the seriousness of AF as a public health burden: in addition to being a well–known risk factor for stroke, AF is also associated with increased risk of MI.

Methods

  • A prospective cohort of 23 928 participants residing in the continental United States and without coronary heart disease at baseline were enrolled from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) cohort between 2003 and 2007, with follow–up through December 2009.
  • Expert–adjudicated total MI events (fatal and nonfatal).

Results

  • Over 6.9 years of follow–up (median 4.5 years), 648 incident MI events occurred.
  • In a sociodemographic–adjusted model, AF was associated with about 2–fold increased risk of MI (hazard ratio [HR], 1.96 [95% CI, 1.52–2.52]).
  • This association remained significant (HR, 1.70 [95% CI, 1.26–2.30]) after further adjustment for total cholesterol, high–density lipoprotein cholesterol, smoking status, systolic blood pressure, blood pressure–lowering drugs, body mass index, diabetes, warfarin use, aspirin use, statin use, history of stroke and vascular disease, estimated glomerular filtration rate, albumin to creatinine ratio, and C–reactive protein level.
  • In subgroup analysis, the risk of MI associated with AF was significantly higher in women (HR, 2.16 [95% CI, 1.41–3.31]) than in men (HR, 1.39 [95% CI, 0.91–2.10]) and in blacks (HR, 2.53 [95% CI, 1.67–3.86]) than in whites (HR, 1.26 [95% CI, 0.83–1.93]); for interactions, P = .03 and P = .02, respectively.
  • On the other hand, there were no significant differences in the risk of MI associated with AF in older (>=75 years) vs younger (<75 years) participants (HR, 2.00 [95% CI, 1.16–3.35] and HR, 1.60 [95% CI, 1.11–2.30], respectively); for interaction, P = .44.

Caffeine intake and atrial fibrillation incidence: Dose response Meta-analysis of prospective cohort studies 
Canadian Journal of Cardiology, 01/25/2014 
 Evidence Based Medicine  Review Article

Cheng M, et al. – The association between habitual caffeine intake with incident AF was unknown. The authors conducted meta–analysis to investigate the association between chronic exposure of caffeine and the risk of atrial fibrillation (AF) and to evaluate the potential dose–response relation. It is unlikely that caffeine consumption causes or contributes to AF. Habitual caffeine consumption may reduce AF risk.

Methods

  • They searched Pubmed, Embase and the Cochrane library up to November 2013 and references of retrieved relevant articles.
  • Prospective cohort studies were included with relative risk or hazard ratio and 95% confidence intervals for AF according to coffee/caffeine intake.

Results

  • Six prospective cohort studies with 228,465 participants were included.
  • In primary meta–analysis, caffeine exposure was weakly associated with a reduced risk of AF (RR 0.90; 95% CI 0.81 to 1.01, P = 0.07; I2 = 73%).
  • In subgroup analyses, pooled results from studies with adjustment of potential confounders showed a 11% reduction for low doses (RR 0.89; 95% CI 0.80 to 0.99, P = 0.032; I2 = 30.9%, P = 0.227) and 16% for high doses (RR 0.84; 95% CI 0.75 to 0.94, P=0.002; I2 = 24.1%, P = 0.267) of caffeine consumption in AF risk.
  • An inverse relation was found between habitual caffeine intake and AF risk (P for overall trend = 0.015, P for nonlinearity = 0.27) in dose response meta–analysis and the incidence of AF decreased by 6 % (RR 0.94; 95% CI 0.90 to 0.99) for every 300 mg/day increment in habitual caffeine intake.

Antihypertensive treatment and risk of atrial fibrillation: A nationwide study 
European Heart Journal, 01/25/2014 
 Clinical Article

Marott SCW, et al. – The study aims to examine the associations between antihypertensive treatment with angiotensin–converting enzyme inhibitors (ACEis) or angiotensin receptor blockers (ARBs), β–blockers, diuretics, or calcium–antagonists, and risk of atrial fibrillation. They examined these associations using the entire Danish population from 1995 through 2010. Use of ACEis and ARBs compared with β–blockers and diuretics associates with a reduced risk of atrial fibrillation, but not stroke, within the limitations of a retrospective study reporting associations. This suggests that controlling activation of the renin–angiotensin system in addition to controlling blood pressure is associated with a reduced risk of atrial fibrillation.

Methods

  • Excluding medication used in atrial fibrillation, the authors matched individuals on ACEi monotherapy 1:1 with individuals on β–blocker (n=48658), diuretic (n=69630), calcium–antagonist (n=57646), and ARB monotherapy (n=20158).
  • Likewise, individuals on ARB monotherapy were matched 1:1 with individuals on β–blocker (n=20566), diuretic (n=20832), calcium–antagonist (n=20232), and ACEi monotherapy (n=20158).
  • All were free of atrial fibrillation and of predisposing diseases like heart failure, ischaemic heart disease, diabetes mellitus, and hyperthyroidism at baseline and none received any other antihypertensive medication.
  • They studied risk of atrial fibrillation, and used risk of stroke, influenced by lowering blood pressure rather than renin–angiotensin system blockade per se, as an indicator of the importance of blood pressure lowering per se.

Results

  • Hazard ratios of atrial fibrillation for ACEi and ARB monotherapy were 0.12 (95% CI: 0.10–0.15) and 0.10 (0.07–0.14) compared with &breta;–blocker, 0.51 (0.44–0.59) and 0.43 (0.32–0.58) compared with diuretic, and 0.97 (0.81–1.16) and 0.78 (0.56–1.08) compared with calcium–antagonist monotherapy.
  • Risk of stroke did not differ among the five antihypertensive medications.

Venous thromboembolism heightens risk for atrial fibrillation, study finds 
A study in the Journal of the American Heart Association found that the risk of developing atrial fibrillation was higher for people with incident venous thromboembolism. Researchers analyzed data involving 29,974 study participants. "Our findings support the concept that right ventricular pressure overload causes persistent right-sided ventricular dysfunction and strain, resulting in atrial stretch and subsequent fibrillation," the study team concluded.Healio (free registration)/Cardiology Today 

Plasma phospholipid omega-3 fatty acids and incidence of postoperative atrial fibrillation in the OPERA trial Full Text 
Journal of the American Heart Association, 01/25/2014 
 Clinical Article

Wu JHY, et al. – Long-chain polyunsaturated omega-3 fatty acids (n-3 PUFA) demonstrated antiarrhythmic potential in experimental studies. In a large multinational randomized trial (OPERA), perioperative fish oil supplementation did not reduce the risk of postoperative atrial fibrillation (PoAF) in cardiac surgery patients. However, whether presupplementation habitual plasma phospholipid n-3 PUFA, or achieved or change in n-3 PUFA level postsupplementation are associated with lower risk of PoAF is unknown. Among patients undergoing cardiac surgery, neither higher habitual circulating n-3 PUFA levels, nor achieved levels or changes following short-term fish oil supplementation are associated with risk of PoAF.

Methods

  • In 564 subjects undergoing cardiac surgery between August 2010 and June 2012 in 28 centers across 3 countries, plasma phospholipid levels of eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA) were measured at enrollment and again on the morning of cardiac surgery following fish oil or placebo supplementation (10 g over 3 to 5 days, or 8 g over 2 days).
  • The primary endpoint was incident PoAF lasting ≥30 seconds, centrally adjudicated, and confirmed by rhythm strip or ECG.
  • Secondary endpoints included sustained (≥1 hour), symptomatic, or treated PoAF; the time to first PoAF; and the number of PoAF episodes per patient.
  • PoAF outcomes were assessed until hospital discharge or postoperative day 10, whichever occurred first.

Results

  • Relative to the baseline, fish oil supplementation increased phospholipid concentrations of EPA (+142%), DPA (+13%), and DHA (+22%) (P<0.001 each).
  • Substantial interindividual variability was observed for change in total n-3 PUFA (range=-0.7% to 7.5% after 5 days of supplementation).
  • Neither individual nor total circulating n-3 PUFA levels at enrollment, morning of surgery, or change between these time points were associated with risk of PoAF.
  • The multivariable-adjusted OR (95% CI) across increasing quartiles of total n-3 PUFA at enrollment were 1.0, 1.06 (0.60 to 1.90), 1.35 (0.76 to 2.38), and 1.19 (0.64 to 2.20); and for changes in n-3 PUFA between enrollment and the morning of surgery were 1.0, 0.78 (0.44 to 1.39), 0.89 (0.51 to 1.55), and 1.01 (0.58 to 1.75).
  • In stratified analysis, demographic, medication, and cardiac parameters did not significantly modify these associations.
  • Findings were similar for secondary PoAF endpoints.

Relation of hypothyroidism and incident atrial fibrillation (from the Framingham heart study) 
American Heart Journal, 01/25/2014 
 Clinical Article

Kim EJ, et al. – Hyperthyroidism has a well–described association with atrial fibrillation (AF). However, the relation of hypothyroidism to AF has had limited investigation. Hypothyroidism is associated with cardiovascular risk factors, subclinical cardiovascular disease, and overt cardiovascular disease, all of which predispose to AF. The authors investigated 10–year incidence of AF in a community–dwelling cohort. They did not identify a significant association between hypothyroidism and 10–year risk of incident AF in a community–based study.

New Ragweed Allergy Immunotherapy Gets Votes of Confidence from FDA Advisers

By the Editors An FDA advisory committee voted on Tuesday in support of the safety and efficacy of an experimental sublingual tablet to treat ragweed allergy. Adults with ragweed allergy would take Ragwitek — made up of ragweed pollen extracts — daily beginning at least 12 weeks before the start of ragweed pollen season until the season ends.The FDA typically follows the advice of its advisory panels when making drug approval decisions, but is not required to do so.

Beta blockers and atrial fibrillation: Hypertension and other medical conditions influencing their use 
Canadian Journal of Cardiology, 12/28/2013 
 Clinical Article

Dorian P, et al. – Beta blockers are amongst the most frequently used drugs in patients with atrial fibrillation. They are often used for ventricular rate control and occasionally to prevent the first occurrence or recurrence of atrial fibrillation, particularly in patients with hypertension. They are also indicated in patients with heart failure or coronary artery disease and atrial fibrillation; the choice of beta blockers in these conditions should be guided by evidence, tolerability and effects on symptoms.

  • Beta blockers are amongst the most frequently used drugs in patients with atrial fibrillation.
  • They are often used for ventricular rate control, both acutely in emergency situations and chronically, in patients with persistent or permanent atrial fibrillation.
  • They are also used, with less evidence of benefit, to prevent the first occurrence or recurrence of atrial fibrillation, particularly in patients with hypertension.
  • They are effective in reducing ventricular rate, potentially leading to an improvement in symptoms and well–being.
  • They are particularly indicated in patients with heart failure and atrial fibrillation; the choice of beta blockers in this condition should be guided by tolerability and effects on symptoms and well–being.

Effects of changing guidelines on prescribing aspirin for primary prevention of cardiovascular events Full Text 
Journal of the American Board of Family Medicine, 01/07/2014 
 Clinical Guideline

Hissett J, et al. – The use of low–dose aspirin for primary prevention of cardiovascular events in patients at elevated risk for cardiovascular disease (CVD) is increasingly being questioned. Aspirin may not benefit this population and may increase the risk of major bleeding events. Data support aspirin use in patients with known CVD. Primary care clinicians have a central role in providing evidence–based preventive services and should integrate revised information into their practice to improve outcomes. Even with new evidence against the use of aspirin for primary prevention, it is difficult to change beliefs about the effectiveness and safety of aspirin, as reflected in the behavior of physicians and patients.

Green Tea May Interfere With Antihypertensive

 (HealthDay News) – Drinking green tea may lessen the effects of the antihypertensive medication nadolol (Corgard), according to research published online Jan. 13 in Clinical Pharmacology & Therapeutics.

Shingen Misaka, PhD, from Fukushima Medical University in Japan, and colleagues gave 10 volunteers a single dose of 30mg of nadolol after they had consumed either water or about three cups of green tea daily for 14 days.

The researchers found that blood levels of the drug were 76% lower in the group that drank green tea compared to the water-drinking group.

"Individuals who take nadolol and also consume green tea should be aware of this potential interaction and discuss this with their physician," Gregg Fonarow, MD, a professor of cardiology at the University of California, Los Angeles, and a spokesman for the American Heart Association, told HealthDay. He reviewed the findings but did not take part in the study.

The American College of Physicians recommends that transfusions and erythropoiesis-stimulating agents be restricted to patients with more-severe anemia.

Sponsoring organization: American College of Physicians (ACP)

Target Population: Primary care physicians, cardiologists

Background and Objective

Treatments for anemia in patients with heart disease include erythropoiesis-stimulating agents (ESAs), red blood cell (RBC) transfusions, and iron replacement, but whether these treatments improve outcomes is unclear. The ACP's new guideline is based on a systematic review of evidence on benefits and harms of these treatments in patients with congestive heart failure (CHF) or coronary heart disease (CHD).

Key Points

— Treatment with RBC transfusions (low-quality evidence)

·         No short-term mortality benefit was found for liberal RBC transfusion versus more restrictive transfusion (hemoglobin trigger level, >10 g/dL vs. 8–9 g/dL) in medical and surgical patients with anemia and heart disease.

·         Aggressive treatment of anemia with RBC transfusions doesn't benefit and might harm patients with acute coronary syndrome or myocardial infarction or those who are undergoing percutaneous coronary interventions.

— Treatment with ESAs (moderate- to high-quality evidence)

·         Among anemic patients with stable CHF, ESA use does not lower all-cause mortality or risk for adverse cardiovascular events but might be associated with harms, such as venous thromboembolism.

Recommendations

·         Use a restrictive RBC transfusion strategy (trigger hemoglobin threshold, 7–8 g/dL) in hospitalized patients with anemia and CHD (grade: weak recommendation; low-quality evidence).

·         Do not use ESAs in patients with mild-to-moderate anemia and CHF or CHD (grade: strong recommendation; moderate-quality evidence).

COMMENT

Patients with heart disease often have anemia, and treating them aggressively intuitively seems like the best choice. However, this clinical practice guideline emphasizes that more (e.g., red blood cells) is not always better and clarifies how and when we should intervene.

Differential patterns of insulin secretion and sensitivity in patients with type 2 diabetes mellitus and nonalcoholic fatty liver disease versus patients with type 2 diabetes mellitus alone Full Text 
Lipids in Health and Disease, 01/08/2014 
 Evidence Based Medicine  Clinical Article

Chai SY, et al. – Nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes mellitus (T2DM) often coexist and have adverse outcomes. The aim of the study was to elucidate metabolic abnormalities in patients with DM–NAFLD versus those with T2DM alone. In patients with similar levels of insulin resistance and hyperglycemia, DM–NAFLD was associated with higher serum insulin levels than T2DM alone. Hyperinsulinemia is caused mainly by beta–cell hypersecretion. The present study demonstrates pathophysiological differences in mechanisms of insulin resistance in patients with DM–NAFLD versus T2DM alone.

Methods

  • Patients were divided into two groups: 26 T2DM patients with NAFLD and 26 gender–, age–, and body mass index–matched patients with T2DM alone.
  • Patients took a 75–g oral glucose tolerance test (OGTT), which measured serum insulin and C–peptide(C–p) levels at baseline (0 min), 30 min, 60 min, and 120 min after glucose challenge.

Results

  • Patients with DM–NAFLD or T2DM alone had similar blood glucose levels. beta–cell hypersecretion was more obvious in patients with DM–NAFLD.
  • In addition, fasting, early–phase, and late–phase C–peptide levels were significantly increased in patients with DM–NAFLD (DeltaC–p 0–30 min, P < 0.05; Area Under the Curve(AUC) C–p/PG 30–120 min ratio, P < 0.01; and AUC C–p 30–120 min, P < 0.01).
  • Hepatic and extrahepatic insulin resistance during the OGTT did not differ significantly between groups.
  • Hepatic insulin sensitivity independently contributed to the early phase (0–30 min) of the OGTT in patients with T2DM and NAFLD, whereas a significant deficit in late insulin secretion independently contributed to the 30–120 min glucose status in patients with T2DM only.

Chinese Herbals Delay Progression to Type 2 Diabetes

By Amy Orciari Herman

A combination of Chinese herbal medicines can delay progression to diabetes in high-risk patients, according to a small study in the Journal of Clinical Endocrinology and Metabolism.

Some 400 patients in China with impaired glucose tolerance were randomized to receive Tianqi -- a capsule containing 10 Chinese herbal medicines -- or placebo for 12 months (5 capsules 3 times daily). All participants also received lifestyle education.

At the end of the study, significantly fewer Tianqi patients than placebo recipients had progressed to diabetes (18% vs. 29%). In addition, significantly more Tianqi recipients had achieved normal glucose tolerance (63% vs. 47%). Adverse events did not differ between groups.

The researchers say Tianqi offers similar benefits to metformin and may be better tolerated. Calling for larger clinical trials, they conclude: "Tianqi holds promising potential as an effective and practical means to prevent [type 2 diabetes]."
