Parents of children with attention deficit hyperactivity disorder (ADHD) are often concerned about the safety and long-term effects of medications used to help manage  ADHD symptoms. But a recent animal study by a Wake Forest Baptist research team suggests that these fears may be unfounded. In this study of juvenile monkeys, the researchers found that Ritalin – the stimulant drug most commonly prescribed for ADHD – did not affect the developing brain, physical growth, or increase the risk of later substance abuse.

More than 90 percent of primary care doctors and 65 percent of oncologists do not know the major long-term side effects of four drugs commonly used to treat breast cancer and colon cancer, according to findings from a survey by the National Cancer Institute.

Weight lifting and other forms of resistance training may help older women with early signs of cognitive decline, such as memory loss, slow that decline and perhaps stave off dementia. These results are based on a small proof-of-concept study reported April 26, 2012 in the journal Archives of Internal Medicine.

The study was conducted by a research team led by Teresa Liu-Ambrose of the Centre for Hip Health and Mobility at Vancouver Coastal Health  Other investigators were from the University of British Columbia.

Insomnia can worsen the effect of tinnitus on physical and emotional health, according to results of a small retrospective study by a group of investigators at Henry Ford Hospital in Detroit, Michigan.

A popular bodybuilding supplement does not live up to its labels’ promises of improved muscle strength and endurance, said two unrelated groups of researchers this summer. The supplement, arginine-alpha-ketoglutarate (AAKG), is widely marketed as a strength-enhancer to weight lifters and bodybuilders. For example, AAKG is supposed to “extend muscle pump, enhance muscle growth, and get rock-hard muscles.” Evidence from these two studies, however, suggests that AAKG may actually decrease performance and have no effect on blood flow.

Researchers have identified a new strain of gonorrhea that is resistant to cephalosporin, the only antibiotic that can be used to treat the disease.

Second, in the lab, it rapidly passed the genes for resistance to other strains of gonorrhea.
