Nutritional supplementation improves immune function and survival in HIV-infected people, according to findings presented here at AIDS 2010: XVIII International AIDS Conference.

In 3 studies conducted in the United States and Botswana, supplementation with vitamin and mineral antioxidants was associated with longer survival, less immune failure, and better mitochondrial function in CD4+ cells, Marianna K. Baum, PhD, said in a poster session. Dr. Baum, who is professor of dietetics and nutrition at Florida International University in Miami, participated in all 3 investigations.

The first 2 studies were small preliminary trials involving HIV-infected patients in Miami, about half of whom were homeless, Dr. Baum told Medscape Medical News.

Adult obesity rates increased in 28 states in the past year, with the No. 1 ranking going to Mississippi, where 33.8% of adults are obese, according to a new report, "F as in Fat: How Obesity Threatens America's Future 2010."

Other major findings in the report:

* 38 states have adult obesity rates above 25%. (No state had an obesity rate above 20% in 1991.)
* 10 of the 11 states with the highest rates of obesity are in the South.
* The number of states where obesity rates exceed 30% has doubled in the past year, from four to eight -- Alabama, Arkansas, Kentucky, Louisiana, Mississippi, Oklahoma, Tennessee, and West Virginia.

Link Between Vitamin D And Mental Agility In Elders PDF Print E-mail

At a time when consumer interest in health-enhancing foods is high, Agricultural Research Service (ARS)-funded scientists have contributed to a limited but growing body of evidence of a link between vitamin D and cognitive function.

Cognitive function is measured by the level at which the brain is able to manage and use available information for activities of daily life. Alzheimer's disease, the most common form of age-related dementia, affects about 47 percent of adults aged 85 years or older in the United States. Identifying nutritional factors that lower cognitive dysfunction and help preserve independent living provides economic and public health benefits, according to authors.

FDA: Antibiotics in Livestock Affects Human Health PDF Print E-mail
Tuesday, 29 June 2010 10:56
Giving animals antibiotics in order to increase food production is a threat to public health and should be stopped, the FDA said today.

The federal agency says it has the power to ban the practice, but it's starting by issuing "draft guidance" in hopes the food industry will make voluntary changes. After a 60-day public comment period, the guidance will become FDA policy.

The guidance is based on two principles:

* Antibiotics should be given to food animals only to protect their health.
* All animal use of antibiotics should be overseen by veterinarians.

"We are seeing the emergence of multidrug-resistant pathogens," FDA Deputy Commissioner Joshua Sharfstein, MD, said at a news conference. "FDA believes overall weight of evidence supports the conclusion that using medically important antimicrobial drugs for production purposes is not appropriate."

Heart risks linked to diabetes drug PDF Print E-mail

A recent study has revealed that the use of diabetes drug rosiglitazone is associated with an increased risk for heart attack.

Rosiglitazone was approved in 1999 to treat hyperglycemia (high blood glucose levels) among patients with type 2 diabetes. Concerns about the cardiovascular safety of rosiglitazone first arose in 2007, when a meta-analysis demonstrated a significantly increased risk for myocardial infarction (heart attack) and a borderline significant increase for cardiovascular death.

Magnets can improve Alzheimer's symptoms PDF Print E-mail
Thursday, 24 June 2010 00:00
To sceptics of alternative medicine, it will come as a surprise. Applying magnets to the brains of Alzheimer's disease sufferers helps them understand what is said to them. The finding by Italian scientsts, who conducted a randomised controlled trial of the treatment, suggests that magnets may alter "cortical activity" in the brain, readjusting unhealthy patterns caused by disease or damage. The study was small, involving just 10 patients, and the results are preliminary.

But the scientists from Brescia and Milan say they "hold considerable promise, not only for advancing our understanding of brain plasticity mechanisms, but also for designing new rehabilitation strategies in patients with neurodegenerative disease."
Ginkgo biloba cuts Alzheimer's risk by 47pc PDF Print E-mail
Thursday, 24 June 2010 00:00
A new study has suggested that long-term use of a ginkgo biloba extract can decrease the risk of Alzheimer's disease by 47 percent.

In the French GuidAge study, groups of elderly people with memory complaints were randomly assigned 240 milligrams per day of ginkgo extract, or a placebo, to be taken daily.

Researchers found that four years later, 29 out of 966 people who were given the placebo developed Alzheimer's disease, compared with 15 out of 947 of the subjects who took the ginkgo extract EGb 761.

Americans spend twice as much as residents of other developed countries on healthcare, but get lower quality, less efficiency and have the least equitable system, according to a report released on Wednesday.

The United States ranked last when compared to six other countries -- Britain, Canada, Germany, Netherlands, Australia and New Zealand, the Commonwealth Fund report found.

"As an American it just bothers me that with all of our know-how, all of our wealth, that we are not assuring that people who need healthcare can get it," Commonwealth Fund president Karen Davis told reporters in a telephone briefing.

Those whose diet includes rice need to watch out for the type of rice they eat to avoid the risk of developing diabetes.

In a first of its kind study, U.S. researchers have found that people who consume brown risk lower their risk of diabetes than those eating its refined counterparts.

Rice is the staple diet of two-thirds of the world's population.

Common blood pressure drug 'raises cancer risk' PDF Print E-mail
Monday, 14 June 2010 00:00
A blood pressure drug used by millions of adults could be increasing their risk of cancer, a study has revealed.

The use of ARB drugs to treat hypertension is associated with a 'modestly increased risk' of new cancer diagnosis, scientists say.

Some 15million prescriptions are written for the drugs every year in the UK - making them one of the most widely-used form of blood pressure medication.
