Although most victims survive the 735,000 heart attacks that occur annually in the U.S., their heart tissue is often irreparably damaged -- unlike many other cells in the body, once injured, heart cells cannot regenerate.

WASHINGTON--The Endocrine Society is commemorating International Women's day with its March 2019 Women in Endocrinology Collection, a special online thematic issue of peer-reviewed journal articles.

WASHINGTON--Researchers will explore the link between unhealthy snack intake and screen time, long-term opioid use and its impact on men's testosterone levels, and other emerging science during news conferences at ENDO 2019, the Endocrine Society's annual meeting taking place March 23-26 in New Orleans, La.

The Society is debuting two new Clinical Practice Guidelines at the news conferences, which will be webcast at

Eighty-six percent of individuals who entered HIV care soon after diagnosis maintained viral suppression after 48 weeks during a clinical trial conducted at four National Institutes of Health (NIH)-funded Centers for AIDS Research (CFARs) across the United States. Participants in the clinical trial, called iENGAGE, achieved viral suppression in an average of just 63 days.

Testosterone replacement is increasingly used by older men, particularly in the United States. The Food and Drug Administration has warned of the risk of heart attack and stroke on testosterone, and requested a large randomized controlled trial to assess the cardiovascular effects of testosterone.

States with more permissive gun laws and greater gun ownership have higher rates of mass shootings, and a growing divide is emerging between states with restrictive versus permissive gun laws. According to a new study, researchers at Columbia Mailman School of Public Health found that in most years permissive states had higher mass shooting rates compared to restrictive states.

New research suggests two-thirds (67%) of pregnant women in London aged between 16 and 24 years have mental health problems including depression, anxiety disorders, post-traumatic stress disorder and obsessive compulsive disorder, according to new research funded by the National Institute for Health Research (NIHR). Anxiety disorders, in particular social phobia, are especially high.

By comparison, the research suggests roughly one in five (21%) pregnant women in London aged 25 years and over have mental health problems.

Riyadh, Saudi Arabia 7 March 2019: Waterpipe and cigarette smoking are associated with heart attacks at a younger age in Saudi Arabians, reports a study presented at the 30th Annual Conference of the Saudi Heart Association (SHA 30). Smokers have more complications and worse outcomes.

SHA 30 takes place from 7 to 9 March in Riyadh. Joint scientific sessions are being held by the European Society of Cardiology (ESC) and SHA as part of the ESC Global Activities programme.1

DALLAS - March 6, 2019 - UT Southwestern researchers used cryo-electron microscopy (cryo-EM) to determine the near-atomic structure of the smallest membrane protein solved to date. Their work could lead to better immunotherapies in cancer and improved treatments for autoimmune diseases like lupus.

An estimated 15 to 20 percent of all breast cancer patients are "triple negative." These unfortunate women lack three crucial treatment targets--the estrogen receptor, the progesterone receptor and human epidermal growth factor receptor 2. Because they lack these targets, most triple negative patients are treated with standard chemotherapy, rather than the preferred targeted drugs. Triple negative breast cancer (TNBC) also disproportionately affects younger women, women of African descent and women with mutations in the BRCA1 gene.
