Sodium is back in the health concern cycle and an analysis of data in the federal nationwide dietary intake survey known as "What We Eat in America NHANES 2009-2010," has led a team of Department of Agriculture (USDA) to conclude that, on any given day 49 percent of U.S. adults eat at least one sandwich, and sandwiches account for 20 percent of total daily sodium intake. 

By studying identical twins, researchers from Lund University in Sweden have identified mechanisms that could be behind the development of type 2 diabetes. This may explain cases where one identical twin develops type 2 diabetes while the other remains healthy.

The study involved 14 pairs of identical twins in Sweden and Denmark. One twin had type 2 diabetes and the other was healthy. Fat tissue can release hormones and regulate metabolism in different organs in the body. The question the researchers posed was whether epigenetic changes in the DNA lead to changes in the fat tissue that in turn can lead to the development of type 2 diabetes. 

A new study has found that people with multiple sclerosis may reduce perceived fatigue and increase mobility through a series of combined strength training and fitness exercises. 

The research from the Miguel Hernández University of Elche, supervised by Professor Raúl Reina, aimed to analyze the effects of strength training on the fatigue that MS patients suffer. A total of 19 participants (5 men and 14 women) were split into two groups. Most took part in a 12-week training program, whilst others were included in a control group. The research was conducted in collaboration with the Neurology Department of Elche General Hospital.

Periodontitis, gum infection that damages the soft tissue and destroys the bone that supports teeth, is the sixth most prevalent condition in the world affecting 743 million people worldwide, according to research from 2010.

Between 1990 and 2010, the global age-standardized prevalence of severe periodontitis was static at 11.2%. The age-standardized incidence of severe periodontitis in 2010 was 701 cases per 100,000 person-years, a non-significant increase from the 1990 incidence of severe periodontitis.

The human papillomavirus (HPV) vaccine has been controversial in both the United States and European countries like Germany. It prevents about 70% of cervical cancers, cervical cancer is uncommon and highly treatable, and it will need another vaccine before girls who are given it even become adults. Along with those data issues, academic scientists and the public have been engaged in a culture war against pharmaceutical companies - that vaccines are exempt from ordinary lawsuits and that the vaccine was marketed heavily just after an expensive settlement by manufacturer Merck was not lost on the public.
