Genetic risk for autism stems mostly from common genes

Genetic risk for autism stems mostly from common genes

Using new statistical tools, Carnegie Mellon University’s Kathryn Roeder has led an international team of researchers to discover that most of the genetic risk for autism comes from versions of genes that are common in the population rather than from rare variants or spontaneous glitches. Published in the July 20 issue of the journal Nature Genetics , the study found that about 52 percent of autism was traced to common genes and rarely inherited variations, with spontaneous mutations contributing a modest 2.6 percent of the total risk Continue reading

Metabolic enzyme stops progression of most common type of kidney cancer

Metabolic enzyme stops progression of most common type of kidney cancer

In an analysis of small molecules called metabolites used by the body to make fuel in normal and cancerous cells in human kidney tissue, a research team from the Perelman School of Medicine at the University of Pennsylvania identified an enzyme key to applying the brakes on tumor growth.

Offering option of initial HIV care at home increases use of antiretroviral therapy

Offering option of initial HIV care at home increases use of antiretroviral therapy

LSTM Researchers found that offering adults in Malawi optional home initiation of care following HIV self-testing resulted in a significant increase in the proportion of adults initiating antiretroviral therapy (ART) compared with standard HIV care. The results are part of a study that was funded by the Wellcome Trust and published in the July 23/30 issue of JAMA , which is HIV/AIDS themed and released early to coincide with the International AIDS Conference taking place in Melbourne, Australia next week. In 2012 it was estimated that 35 million people worldwide were living with the human immunodeficiency virus (HIV). Continue reading

Combination treatment for hep C associated with favorable response among HIV patients

HIV-infected patients also infected with hepatitis C virus (HCV) who received a combination of the medications sofosbuvir plus ribavirin had high rates of sustained HCV virologic response 12 weeks after cessation of therapy, according to a study in the July 23/30 issue of JAMA , a theme issue on HIV/AIDS. The issue is being released early to coincide with the International AIDS Conference Continue reading

New trigger for ovulation could make IVF safer

New trigger for ovulation could make IVF safer

Researchers have successfully used a new and potentially safer method to stimulate ovulation in women undergoing IVF treatment. Twelve babies have been born after their mothers were given an injection of the natural hormone kisspeptin to make their eggs mature. Doctors normally administer another hormone, hCG, for this purpose, but in some women, there is a risk that this can overstimulate the ovaries, with potentially life-threatening consequences.

Immune cell’s role in intestinal movement may lead to better understanding of irritable bowel syndrome

Immune cell’s role in intestinal movement may lead to better understanding of irritable bowel syndrome

Learning the role of immune-system cells in healthy digestive tracts and how they interact with neighboring nerve cells may lead to new treatments for irritable bowel syndrome (IBS). Researchers from Penn State College of Medicine, in collaboration with other scientists, have reported the role of macrophages in regulating the contractions of the colon to push digested material through the digestive tract. The muscular lining of the intestine contains a distinct kind of macrophage, an immune system cell that helps fight infections Continue reading

Genetic variations may modify cardiovascular benefit of aspirin

Genetic variations may modify cardiovascular benefit of aspirin

Aspirin is the gold standard for antiplatelet therapy and a daily low-dose aspirin is widely prescribed for the prevention of cardiovascular disease. Now, a new study suggests that common genetic variation in the gene for catechol-O-methyltransferase (COMT) may modify the cardiovascular benefit of aspirin, and in some people, may confer slight harm Continue reading
