A full house raises risk of hospital deaths

A new study published in Medical Care found that high hospital occupancy is associated with a 5.6% increased risk of patient death, while nurse staffing levels can decrease this risk by 6%. Weekend admissions also increase the risk of death by 7.5%, while seasonal flu raises it by 11.7%.

Obesity as protection against metabolic syndrome, not its cause

According to Roger Unger, obesity is the body's way of storing lipids in fat tissue to protect other organs. This protective mechanism fails when the body's fat tissue can't handle excess calories, leading to metabolic syndrome. The rise of leptin resistance also plays a key role in this process.
