WEDNESDAY, Nov. 21, 2018 -- Smoking bans in public places might protect more than the lungs of nonsmokers, with new research suggesting a beneficial effect on blood pressure.
"We found that nonsmoking adults in the study who lived in areas with smoke-free laws in restaurants, bars or workplaces had lower systolic [top number] blood pressure by the end of the follow-up period compared to those who lived in areas without smoke-free laws," said lead author Stephanie Mayne. She is a research scientist at the Center for Pediatric Clinical Effectiveness at Children's Hospital of Philadelphia.

But also use this time to learn proper form, the American College of Sports Medicine advises. As you progress, you can zero in on the best amount of weight as well as the number of repetitions and sets of repetitions you do.
TUESDAY, Nov. 20, 2018 -- For the first time, a highly influential panel of experts says doctors should offer a daily pill to prevent HIV transmission to people who are at high risk for infection with the AIDS-causing virus.
This treatment is called pre-exposure prophylaxis -- PrEP for short -- and it has been shown to be highly effective at preventing HIV's spread, concluded the U.S. Preventive Services Task Force. USPSTF panels regularly convene to issue evidence-based guidance on a wide variety of medical matters. Their advisories help inform care and insurance coverage.
TUESDAY, Nov. 20, 2018 -- As the U.S. opioid epidemic rages unchecked, new research shows that pregnancy-related deaths due to opioid misuse more than doubled between 2007 and 2016.
Deaths during or soon after pregnancy rose 34 percent during that time, and the percentage involving heroin, fentanyl or prescription painkillers (such as OxyContin) jumped from 4 percent to 10 percent, the researchers said.
TUESDAY, Nov. 20, 2018 -- Women are no more likely than men to have health problems due to strenuous training and extreme physical exertion, researchers report.
"Our findings contain some potentially myth-busting data on the impact of extreme physical activity on women. We have shown that with appropriate training and preparation, many of the previously reported negative health effects can be avoided," said researcher Robert Gifford, from the University of Edinburgh and the Royal Centre for Defence in Scotland.
