Untreated sleep apnea shown to raise metabolic and cardiovascular stress — ScienceDaily

Sleep apnea, left untreated for even a few days, can increase blood sugar and fat levels, stress hormones and blood pressure, according to a new study of sleeping subjects. A report of the study’s findings, published in the August issue of The Journal of Clinical Endocrinology & Metabolism, adds further support for the consistent use of continuous positive airway pressure (CPAP), a machine that increases air pressure in the throat to keep the airway open during sleep.

Jun emphasized that the study was limited by studying people with severe OSA and obesity, thus limiting the ability to apply the findings to all OSA patients. The researchers also did not compare CPAP use to a sham CPAP control group to exclude a potential placebo effect

North Atlantic Clam That Lives for Centuries Yields Insights on Cardiac Aging | NCCIH

The typical heart in aquatic invertebrate animals such as clams, oysters, and mussels has many strong similarities to the human heart. The Arctica islandica, or ocean quahog, is the longest-living, non-colony-dwelling animal ever identified; so far, the oldest identified specimen survived to age 508 (age is identified by counting shell growth rings).

Workplace Suicide Rates Rise Sharply – NPR

Jobs with greatest risk include law enforcement, firefighting and protective services, such as private detectives and security guards. The suicide rate for the group was 1.5 per million workers per year over the study period. The vast majority of these suicides (84 percent) involved firearms. Easy access to guns for some and the high stress in these jobs may both play roles in the workers’ decisions about suicide.
