Effects of Time of Arrival on Trauma Patient Outcomes.

Background: Arriving during "off hours" to the hospital can put patients at greater risk of complications or mortality given lesser staff. Our goal was to investigate this in trauma patients with an Injury Severity Score (ISS) of >15. We hypothesized that the patients admitted late at night and/or during the weekend, would have worse outcomes, delays to the operating room (OR), and longer lengths of stay (LOS) compared to those who arrive on a weekday during the day.

Optimal body weight for the prevention of coronary heart disease in normal-weight physically active men.

Although 36% of US men are normal weight (BMI <25 kg/m(2)), the health benefits of greater leanness in normal-weight individuals are seldom acknowledged. To assess the optimal body weight with respect to minimizing coronary heart disease (CHD) risk, we applied Cox proportional hazard analyses of 20,525 nonsmoking, nondiabetic, normal-weight men followed prospectively for 7.7 years, including 20,301 who provided follow-up questionnaires.
