Multiple sclerosis medication gap: Study finds women less likely than men to receive drugs

A new study has found that, among women with a high desire to avoid becoming pregnant, those who drank heavily had a 50% higher risk of becoming pregnant than those who drank moderately or not at all. In contrast, participants who used cannabis were no more likely to have an undesired pregnancy than participants who did not use cannabis.

A new study published in Addiction has found that young adults in the US do not "titrate" when using strong cannabis. In other words, they do not use less cannabis to compensate for the stronger potency. In fact, it's the opposite: young adults who report using strong cannabis also typically use it more frequently and in higher quantities than young adults who use weaker forms of the drug.

Obesity elevates the risk of at least 13 major cancers, including those of the breast, colon and liver. It also impairs immune responses that target tumors and are stimulated by cancer immunotherapies. But it has long been unclear whether these effects stem from the sheer adiposity—or mass of fat—in people living with obesity or from the specific dietary fats they consume.

Researchers at the National Institutes of Health (NIH) have shown for the first time that a type of human papillomavirus (HPV) commonly found on the skin can directly cause a form of skin cancer called cutaneous squamous cell carcinoma (cSCC) when certain immune cells malfunction.

A multi-institutional team, including physicians and researchers who successfully proposed updates to national guidelines, share important next steps for reevaluating how occupational impairment is determined.

Drivers are not the only ones to blame for roadway fatalities.

The Trump administration is pushing an initiative for millions of Americans to upload personal health data and medical records on new apps and systems run by private tech companies, promising that will make it easier to access health records and monitor wellness.

Nirsevimab is effective for protecting infants against respiratory syncytial virus (RSV)-associated lower respiratory tract disease (LRTD), according to a study published online July 22 in Pediatrics.

Allergic to peanuts? Bees? Pollen? Cockroaches? There's a shot for that.

As temperatures rise, California is experiencing fewer deaths from cold temperatures, which outweigh increased deaths from extreme heat. However, hotter temperatures sharply increase emergency department visits—a previously overlooked consequence of climate change that could place a greater burden on the health care system.

A new study reveals that fragmented sleep causes cellular damage to the brain's blood vessels, providing further evidence to suggest that sleep disruption predisposes the brain to dementia.

Skin cancer is the most common form of cancer worldwide, and early detection is key to successful treatment. While traditional methods rely on visual inspection and biopsy, researchers are developing new technologies that can provide more detailed information without cutting into the skin.

New research published in Proceedings of the National Academy of Sciences (PNAS) finds that prolonged and/or repeated exposure to gamma-aminobutyric acid (GABA) anesthetic agents (sevoflurane, propofol) for infants in the first two months of life resulted in an accelerated maturation of brain electrical activity patterns evoked by visual stimuli when recorded at 2–5 months of age, compared to infants who did not have early general anesthesia exposure.

In a small trial, Mass General Brigham researchers have found that a drug designed to treat celiac disease supported a more rapid return to normal activities for patients following COVID.

A mutant DJ-1 gene causes recessive Parkinson's disease, but the molecular mechanism of this process has not been well studied. To understand how DJ-1 hydrolyzes cyclic 3-phosphoglyceric anhydride—a highly reactive, toxic cellular metabolite—researchers from Japan have performed molecular simulations and biochemical assays, including mutational analyses, confirming DJ-1's role in the pathogenesis of hereditary Parkinson's disease.

The Black Death arrived on the shores of England in May 1348 and, in less than two years, spread throughout the country, killing an estimated 2 million people. The death toll from the disease, which was caused by the bacterium Yersinia pestis, got so high that officials in London and other cities opened new cemeteries where hundreds of bodies were interred every day.

Although metformin has been the go-to medication to manage type 2 diabetes for more than 60 years, researchers still do not have a complete picture of how it works.

A potential new male contraceptive drug has just undergone its first tests in human volunteers. The results give the first indication that the drug, which does not use artificial hormones or affect testosterone production by the testes, may be safe in humans.
