A new study published in JAMA Network Open explores mortality risk among older adults living with dementia who were exposed to major US hurricanes.

Cherenkov imaging is a valuable cancer treatment tool that can help doctors track and monitor radiation doses received by tissues during cancer therapy in real time. This imaging technique works by detecting Cherenkov radiation, which is emitted by tissues exposed to high-energy radiation, such as X-rays or electron beams from a linear accelerator. As high-energy charged particles from the incident radiation pass through biological tissue, either as primary or secondary radiation, they interact with the electromagnetic fields of the atoms and molecules in the tissue. These soft collision-type interactions lead to electromagnetic shifts in the molecules that release Cherenkov radiation when returning to their original state, which can be detected and correlated to the amount of deposited dose from the radiation.

Living in the country, in rural areas, has long been idealized as a pristine place to raise a family. After all, open air and room to run free pose distinct advantages. But new findings from a University of Houston psychology study indicate that Americans who live in more rural areas tend to be more anxious and depressed, as well as less open-minded and more neurotic. The study also revealed those living in the country were not more satisfied with their lives, nor did they have more purpose or meaning in life than people who lived in urban areas.

COVID-19 can cause difficulty recognizing faces and navigational problems, according to a new Dartmouth study in Cortex.

In the United States, low-income, Latino youth are disproportionately affected by obesity, with 25.8% of Latino youth aged 2-19 considered to have obesity, which is approximately two times more likely when compared to their non-Latino white counterparts. A higher level of obesity results in an increased risk of cardiometabolic diseases, which are a group of related diseases caused by an unhealthy lifestyle and/or an increased genetic predisposition.

A Texas judge favored by anti-abortion activists will hear arguments Wednesday in an unprecedented challenge to the legality of a widely-used abortion pill.

Six mobile vaccine production units by German pharma company BioNTech arrived in Rwanda on Monday, the first such shipments to Africa as the continent seeks to boost mRNA vaccine manufacturing.

Scientists at the National Institutes of Health and Massachusetts General Hospital in Boston have uncovered a potential new approach against liver cancer that could lead to the development of a new class of anticancer drugs. In a series of experiments in cells and mice, researchers found that an enzyme produced in liver cancer cells could convert a group of compounds into anticancer drugs, killing cells and reducing disease in animals.

There is power and value in a highly skilled detective. Sherlock Holmes and his trusty sidekick, Watson, are famous for sifting through enormous amounts of data—identifying patterns and making predictions to uncover a mystery with ease. In the medical world, clinicians are detectives, making diagnoses and drawing conclusions based on their clinical judgment and available patient data. But just like detectives, clinicians can benefit from having a sidekick.

A systematic review of 33 randomized controlled trials (RCTs) found that yoga improved gait speed and lower extremity strength in inactive older people. However, yoga did not seem to offer a benefit for frailty markers over activities like exercise or tai chi. The review is published in Annals of Internal Medicine.
