New research finds rise of frequent cannabis vaping among US high school seniors

Frequent cannabis vaping, defined as vaping at least 10 times a month, more than doubled among high school seniors in the United States between 2018 and 2019, according to new research from NYU Grossman School of Medicine published online May 4 in the Journal of Adolescent Health. The rise in frequent use was even greater in certain subgroups such as students 18 years or older, female students, and those who reported using other drugs within the past year. [...]

Supporting mums' mental health strengthens their 'protective' playmate role with children

Helping parents with depression or anxiety could also improve their ability to engage in potentially 'protective' forms of play with their children, which can reduce the risk of behavioral problems, new research suggests. [...]

Thin and brittle bones strongly linked to women's heart disease risk

Thin and brittle bones are strongly linked to women's heart disease risk, with thinning of the lower (lumbar) spine, top of the thigh bone (femoral neck), and hip especially predictive of a heightened heart attack and stroke risk, suggests research in the journal Heart. [...]

Sugar-sweetened drinks linked to increased risk of colorectal cancer in women under 50

Colorectal cancer diagnoses have increased among people under age 50 in recent years and researchers are seeking reasons why. A new study led by Washington University School of Medicine in St. Louis has found a link between drinking sugar-sweetened beverages and an increased risk of developing colorectal cancer in women under age 50. The findings suggest that heavy consumption of sugary drinks during adolescence (ages 13 to 18) and adulthood can increase the disease risk. [...]

The effects of eliminating race-based adjustments in estimates of kidney function

An ongoing debate is focused on race-based algorithms in medicine—such as an adjustment for Black race in equations that estimate individuals' kidney function. A study appearing in an upcoming issue of JASN examines the impact of dropping this race adjustment on patient care. [...]

WHO warns of new COVID wave in Africa

The World Health Organization on Thursday warned of a new wave of COVID-19 infections in Africa due to delayed vaccine supplies, a slow rollout and new variants. [...]

Online learning doesn't improve student sleep habits, research suggests

New research from Simon Fraser University suggests that students learning remotely become night owls but do not sleep more despite the time saved commuting, working or attending social events. [...]

Skin and immune cells coordinate defenses against assault

As the human body's largest organ, the skin is responsible for protecting against a wide range of possible infections on all fleshy surfaces, from head to toe. So how exactly does the skin organize its defenses against such an array of threats? [...]

Researchers develop mathematical model predicting disease spread patterns

Early on in the COVID-19 pandemic, health officials seized on contact tracing as the most effective way to anticipate the virus's migration from the initial, densely populated hot spots and try to curb its spread. Months later, infections were nonetheless recorded in similar patterns in nearly every region of the country, both urban and rural. [...]

'Natural disasters' increase triggers for violence against women and girls

'Natural disasters,' sparked by climate change and other natural hazards, increase the triggers for violence against women and girls by boosting the means, opportunity, and underlying drivers, finds a review of the available evidence, published in the online journal BMJ Global Health. [...]
