Forty percent of dementia cases could be prevented or delayed by targeting 12 risk factors throughout life

Modifying 12 risk factors over the lifecourse could delay or prevent 40% of dementia cases, according to an update to The Lancet Commission on dementia prevention, intervention, and care, which is being presented at the Alzheimer’s Association International Conference (AAIC 2020). Combined, the three new risk factors are associated with 6% of all dementia cases—with an estimated 3% of cases […]

Immune system could be trained to spot drug-resistant cancers

Aggressive cancers could be treated with immunotherapies that direct the immune system to kill cancer cells with specific drug resistance-causing mutations, a major new study suggests. Drug resistance mutations which restore activity of the BRCA1 or BRCA2 genes as a way of avoiding the effects of drug treatment could leave tumors vulnerable to the effects of immunotherapy, the research found. […]

Low-carbohydrate diet may be associated with lower risk of blinding eye disease

Following a long-term diet that’s low in carbohydrates and high in fat and protein from vegetables may lower the risk of the most common subtype of glaucoma. In a first-of-its-kind study, a researcher at New York Eye and Ear Infirmary of Mount Sinai (NYEE) helped discover that if at-risk groups adhere to these dietary restrictions, they may reduce their risk […]

COVID-19 can be transmitted in the womb, study reports

A baby girl in Texas—born prematurely to a mother with COVID-19—is the strongest evidence to date that intrauterine (in the womb) transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can occur, reports The Pediatric Infectious Disease Journal, the official journal of The European Society for Paediatric Infectious Diseases. The findings “suggest in utero transmission” of COVID-19 from an infected […]

Parents twice as likely to be concerned about ticks than of mosquitoes

Not all bloodsuckers are created equal in parents’ eyes. When it comes to bug bites, parents are twice as likely to be concerned about ticks as they are about mosquitoes transmitting disease, a new national poll finds.

Fear of needles could be a hurdle to COVID-19 vaccination, but here are ways to overcome it

As progress continues toward finding a vaccine that prevents COVID-19, millions of Americans are frightened at even the notion of getting a shot: Studies suggest 63% of young adults—those born in 2000 or later—fear needles. As a physician trained in pediatrics, I think we found the answer for the huge rise in needle phobia. Now—and even more critical: What might […]

How the coronavirus could be prevented from invading a host cell

How might the novel coronavirus be prevented from entering a host cell in an effort to thwart infection? A team of biomedical scientists has made a discovery that points to a solution. The scientists, led by Maurizio Pellecchia in the School of Medicine at the University of California, Riverside, report in the journal Molecules that two proteases—enzymes that break down […]
