Weight-loss surgery prior to pregnancy results in lower prevalence of obesity in children

Adolescent and young children of obese mothers who underwent weight-loss surgery prior to pregnancy have been found to have a lower prevalence of obesity and significantly improved cardio-metabolic markers when compared to siblings born before the same obese mothers had weight-loss surgery. This new study has been accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

New study reveals that moderate aerobic exercise improves insulin sensitivity in obese adolescents

A moderate aerobic exercise program, without weight loss, can improve insulin sensitivity in both lean and obese sedentary adolescents, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). Insulin is a hormone produced in the pancreas that permits glucose to enter cells to be used for energy or stored for future use by the body.

Nighttime acid reflux symptoms impair sleep quality

There has been much debate about the relationship between gastroesophageal reflux disease (GERD) and sleep. Three new studies in Clinical Gastroenterology and Hepatology explore GERD's effect on sleep quality and the health-care system as well as how a widely prescribed sleeping pill may mask the disease.

Rodents may serve as useful models to interpret parent-offspring relationships

Researchers at the Yerkes National Primate Research Center, Emory University, have demonstrated that prairie voles may be a useful model in understanding the neurochemistry of social behavior. By influencing early social experience in prairie voles, researchers hope to gain greater insight into what aspects of early social experience drive diversity in adult social behavior.

Study establishes link between workplace bullying and increased sleep disturbances

A study in the Sept.1 issue of the journal SLEEP shows that current or past exposure to workplace bullying is associated with increased sleep disturbances. Associations also were found between observed bullying and sleep disruption, indicating that bullying has detrimental effects even when it is experienced indirectly.

Natural food compounds may play a vital role in cancer treatment

Research in the Linus Pauling Institute at Oregon State University suggests that some natural food compounds, which previously have been studied for their ability to prevent cancer, may be able to play a more significant role in treating it - working side-by-side with the conventional drugs that are now used in chemotherapy.

Research study to identify the appropriate amount of DHA required for promoting optimal heart health

A team of French scientists have found the dose of DHA (docosahexaenoic acid) that is "just right" for preventing cardiovascular disease in healthy men. In a research report appearing in the September 2009 print issue of The FASEB Journal, the scientists show that a 200 mg dose of DHA per day is enough to affect biochemical markers that reliably predict cardiovascular problems, such as those related to aging, atherosclerosis, and diabetes. This study is the first to identify how much DHA is necessary to promote optimal heart health.

Chemotherapy affects sleep-wake activity rhythms of breast cancer patients

A study in the Sept.1 issue of the journal Sleep shows that the sleep-wake activity rhythms of breast cancer patients are impaired during the administration of chemotherapy. Results indicate that the first cycle of chemotherapy is associated with a temporary disruption of these rhythms, while repeated administration of chemotherapy results in progressively worse and more enduring impairments.
