Landmark study points to source of rapid aging, chronic inflammation in people living with HIV

In a groundbreaking study of people living with HIV, University of Alberta researchers found that elusive white blood cells called neutrophils play a role in impaired T cell functions and counts, as well as the associated chronic inflammation that is common with the virus. Neutrophils are a foundational part of the body’s immune system and the most abundant type of […]

New study provides robust evidence that COVID-19 is a seasonal infection

A new study led by the Barcelona Institute for Global Health (ISGlobal) provides robust evidence that COVID-19 is a seasonal infection linked to low temperatures and humidity, much like seasonal influenza. The results, published in Nature Computational Science, also support the considerable contribution of airborne SARS-CoV-2 transmission and the need to shift to measures that promote “air hygiene.” A key […]

Study explores the decisions made by physicians in the delivery room, and why they may be making them

Clinical decisions made in the delivery setting as to whether to employ vaginal delivery or cesarean section are often made under high pressure, and with great uncertainty, and have serious consequences for mother and baby. Now, a new study of electronic health records spanning 86,000 deliveries suggests that if their prior patient had complications in one delivery mode, a physician […]

New study finds medical debt is a double whammy for the poor

Earlier this summer, Stanford economist Neale Mahoney sounded an alarm with a study he coauthored: Americans have at least $140 billion in unpaid health care bills sitting in collection agencies—making the country’s medical debt crisis far bigger than anyone had realized. Now, in plumbing the repercussions, his latest research finds evidence suggesting that people saddled with unpaid health care bills […]

Study shows testosterone linked with multi-partnerships in men, but with solo sex in women

Testosterone levels appear to be significantly linked with both the type of intimate relationships men and women engage in and their sexual behavior, according to new research published today in the peer-reviewed The Journal of Sex Research. The findings from the third British National Survey of Sexual Attitudes and Lifestyles (Natsal-3) provide the first detailed insights into how the hormone […]

New study shows Americans take precautions against COVID-19, except where most needed

A new study, led by researchers at LSU and University of Wisconsin-River Falls, shows most Americans routinely take precautions against COVID-19 infection—except where most needed: at home. While most people are familiar with expert advice on how COVID-19 is transmitted, know how to stay safe and generally comply with precautionary recommendations, about one-quarter report having had COVID-19. Among them, most […]

Study identifies mechanism by which nicotine withdrawal increases junk food consumption

New data collected by University of Minnesota Medical School researchers demonstrate a clear connection between nicotine withdrawal and poor eating habits. Their findings point to the opioid system, the brain functions responsible for addiction and appetite regulation, as a possible cause for smoker preference of energy-dense, high-calorie food during nicotine withdrawal. This can lead to weight gain, for those who […]
