Drugs prescribed to treat anxiety, depression and insomnia may increase patients’ risk of being involved in motor vehicle accidents, according to a recent study. Based on the findings, the researchers suggested doctors should consider advising patients not to drive while taking these drugs. Psychotropic drugs affect the way the brain functions and can impair a driver’s ability to control their vehicle.

Protection against whooping cough (also called pertussis) waned during the five years after the fifth dose of the combined diphtheria, tetanus, acellular pertussis (DTaP) vaccine, according to researchers. The fifth dose of the DTaP is routinely given to 4- to 6-year-old children prior to starting kindergarten.

The first single gene cause of increased sensitivity to the hormone insulin has been discovered. The opposite condition – insulin resistance – is a common feature of type 2 diabetes, so finding this cause of insulin sensitivity could offer new opportunities for pursuing novel treatments for diabetes.

A number of environmental toxins pose considerable health threats to humans, and the heavy metal cadmium (Cd) ranks high on the list. Most of us are exposed to it through plant-derived foods such as grains and vegetables. Now, new research offers ways in which investigators can reduce the amount of Cd found in the food we eat.

New research indicates marijuana-like compounds called endocannabinoids alter genes and biological signals critical to the formation of a normal placenta during pregnancy and may contribute to pregnancy complications like preeclampsia. A new study offers evidence that abnormal biological signaling by endocannabinoid lipid molecules produced by the body disrupts the movement of early embryonic cells important to a healthy pregnancy.

Soccer, football, cheerleading, gymnastics and other sports run an increased risk of concussion because of the rigorous demands of today's play and practice. Any type of traumatic brain injury, including concussion, requires a monitored approach to complete healing to avoid long-term secondary complications that can affect memory, behavior, anxiety and ability to focus and concentrate.

Post-stroke depression is a major issue affecting approximately 33% of stroke survivors. A new study reports that the level to which survivors are uncertain about the outcome of their illness is strongly linked to depression. The relationship is more pronounced for men than for women.

New research shows that a carefully scheduled high-fat diet can lead to a reduction in body weight and a unique metabolism in which ingested fats are not stored, but rather used for energy at times when no food is available.

Researchers have identified several novel genes that make some children more efficient than others in the way their immune system responds to malaria infection.

Chronic heart failure patients are less likely to have died a year after discharge if they are involved in a programme of active follow-up once they have returned home than patients given standard care, according to a new Cochrane systematic review. These patients were also less likely to need to go back into hospital in the six months that follow discharge.
