Weight Loss Critical to Reduce the Burden of Cardiovascular Risk Factors in Obese Patients with Obstructive Sleep Apnea
Perelman School of Medicine at the University of Pennsylvania

Obesity and obstructive sleep apnea (OSA) tend to co-exist and are associated with a variety of cardiovascular risk factors, including inflammation, insulin resistance, abnormal cholesterol, and high blood pressure. While effective therapies are available for OSA, researchers are still unclear about what interventions are most effective in reducing the burden of risk factors for cardiovascular disease associated with OSA in obese patients. New research from a multidisciplinary team at the Perelman School of Medicine at the University of Pennsylvania now reveals that the single most important factor for improving cardiovascular health in obese OSA patients is weight loss. The study results are published in the New England Journal of Medicine.

Researchers Identify Gene That Helps Fruit Flies Go to Sleep

In a series of experiments sparked by fruit flies that couldn’t sleep, Johns Hopkins researchers say they have identified a mutant gene — dubbed “Wide Awake” — that sabotages how the biological clock sets the timing for sleep. The finding also led them to the protein made by a normal copy of the gene that promotes sleep early in the night and properly regulates sleep cycles.
