Cost effectiveness study looks at potential value of new genetic test for guiding chemotherapy treatment

For the 29,000 patients in the United States with metastatic colorectal cancer, chemotherapy with irinotecan is a standard treatment that has been shown to improve survival. But for more than one in 10 of these patients, a variation in their DNA means that this treatment could result in a severe reduction in their white blood cell count, leading to a high risk of bacterial infection and possible subsequent death.

Research adds to growing understanding of the metabolic consequences of assisted reproductive techniques

Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds that assisted reproductive techniques alter the expression of genes that are important for metabolism and the transport of nutrients in the placenta of mice.

Autophagy helps HIV to proliferate

Not satisfied with simply thwarting its host's defensive maneuvers, HIV actually twists one to its advantage, based on new findings from Kyei et al. in the July 27, 2009 issue of the Journal of Cell Biology. Vojo Deretic and colleagues suggest that autophagy - a stress response process - helps HIV to proliferate and that conversely, blocking autophagy lessens HIV production.

Effect of sunlight exposure on cognitive function among depressed and non-depressed participants

A lack of sunlight is associated with reduced cognitive function among depressed people. Researchers writing in BioMed Central's open access journal Environmental Health used weather data from NASA satellites to measure sunlight exposure across the United States and linked this information to the prevalence of cognitive impairment in depressed people.

Intensive glucose control halves complications of longstanding type 1 diabetes

Near-normal control of glucose beginning as soon as possible after diagnosis would greatly improve the long-term prognosis of type 1 diabetes, concludes a study published in the July 27, 2009, issue of the Archives of Internal Medicine, which updates information about the clinical course of type 1 diabetes.

Diets high in calcium and dairy products in childhood may lower mortality

Suggestive evidence points to the possibility that children who have a diet high in calcium and who consume dairy products may have a lower mortality rate than those who don't, according to a study by researchers in Bristol and Brisbane, published in the journal Heart.

Enzyme implicated in blood flow in Alzheimer’s, disease progression

Researchers have discovered that the enzyme, endothelin converting enzyme-2 (ECE-2), may cause the decrease in blood flow in the brain seen in Alzheimer's disease and contribute to progression of the disease.

Adding a drug called neostigmine to epidural analgesia reduces dose needed during labor

Adding a drug called neostigmine to epidural analgesia during labor can reduce the amount of anesthetic drug required, while avoiding potential complications caused by morphine-like "opioid" drugs, according to a study in the August issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Marital biography and health at mid-life

A stable, long-term marriage can be good for your health, but divorce or widowhood leave a lasting scar on the health of middle-aged and older people, according to a new study. Remarriage seems to reduce but not erase the damage done by losing a marriage, and those who remain single after a marriage ends show consistently worse health than those who remarried.

Antiretroviral syrup for babies, mothers safely reduces HIV transmission

Giving daily antiretroviral syrup to breastfeeding infants or treating their HIV-infected mothers with highly active antiretroviral drugs is safe and effective in preventing mother-to-child HIV transmission through breast milk, a study led by University of North Carolina at Chapel Hill investigators has found.
