Smoking increases likelihood of impotency

A study by Northwestern University researchers found that men who smoke are more likely to experience erectile dysfunction due to the negative effects of smoking on blood vessels. The prevalence of erectile dysfunction in former smokers was similar to that of never-smokers, highlighting the long-term risks of tobacco use.

7-day-on, 7-day-off regimen could reduce cost, toxicities of HIV therapy

Researchers suggest a structured intermittent therapy approach, where patients receive daily doses of HAART for seven days, followed by seven days off the medication. This regimen has shown significant reductions in certain side effects, including cholesterol and triglyceride levels, without compromising treatment efficacy.

Gatekeepers may not be essential to keep HMO costs down

A new study found that eliminating gatekeepers in health maintenance organizations (HMOs) does not necessarily increase costs. In contrast to traditional HMOs, point-of-service plans with open physician panels showed comparable spending on medical care expenditures, including physician services, hospital services, and prescription drugs.

Floods ain't what they used to be; Study shows wing dams have made them worse

A recent study by Washington University in St. Louis researchers attributes increased flood levels on the Missouri and Mississippi rivers to the placement of thousands of wing dams, built by the US Army Corps of Engineers in the 1930s and '40s. The structures impede water flow during floods, causing water levels to rise.
