Frozen meals sold at Walmart, Kroger and Trader Joe's linked to listeria outbreak

Alzheimer's disease is marked by the buildup of amyloid plaques in the brain, but most ways of studying these deposits in mouse models require sacrificing the animals. That limits researchers' ability to follow how the disease develops or how treatments work over time.

The end of pandemic-era enrollment enhancements for Medicaid was associated with a rise in the number of people ending medication treatment for opioid use disorder, as well as a decrease in the number of people beginning such treatment, according to a new RAND study.

After blood vessel damage, effective blood clotting is essential to halt bleeding. However, this process is inefficient in some individuals due to hereditary factors. Hemophilia B, for example, results from a deficiency in coagulation factor IX (FIX), which can lead to prolonged bleeding after injuries or surgery.

In a new study, Yale School of Medicine (YSM) researchers unveiled a novel diagnostic method for detecting leptospiral virulence-modifying (VM) proteins in the blood and urine of hamsters, an advance that could pave the way for early diagnosis of the tropical disease leptospirosis in humans and improved treatment options. The findings appear in the journal Microbiology Spectrum.

For patients with intermediate-risk, localized prostate cancer, radiation therapy delivered in five sessions reduced patient-reported side effects compared to longer courses of radiation, according to results of a large, randomized phase III trial. Patients treated with stereotactic body radiation therapy (SBRT) reported fewer declines in bowel, urinary and sexual functioning but were more likely to experience a rise in prostate-specific antigen (PSA).

The first randomized trial to compare photon- and proton-based radiation therapy for breast cancer finds that patients report equally strong health-related quality of life with either treatment. Patients who received proton therapy were more likely to say they would recommend or choose it again, but overall patient-reported outcomes were similar.

The U.S. Food and Drug Administration (FDA) is reviewing the safety of mifepristone, a drug used in medication abortions for 25 years, amid a push from conservative state attorneys general and anti-abortion groups.

In tissue biopsies, cancer cells are frequently observed to have nuclei (the cell's genetic information storage) that are larger than normal. Until now, this was considered a sign that the cancer was worsening, but the exact cause and effect had not been elucidated.

Uptake of the respiratory syncytial virus (RSV) vaccine during pregnancy is not linked to increased risk of adverse perinatal health outcomes among vaccinated women, according to research at City St George's and published in BMJ Open.

Chronic rhinosinusitis (CRS) is a surprisingly common but under-recognized disease that affects nearly one billion people worldwide, or about 12% of the population. Defined as a long-lasting inflammation of the nose and sinuses that lasts longer than 12 weeks, CRS is like having a bad cold and/or sinus infection that just won't go away.

Rapidly aging populations and rising cases of lifestyle-related diseases (LRDs), like diabetes and hypertension, are driving significant financial strain on government budgets. While regular health checkups under a standardized government program can be a solution, it is not well understood how these initiatives benefit different socioeconomic sections of society and their economic feasibility.

Tooth decay is the most common health condition worldwide. While it is preventable and treatable, billions of people are living with cavities and the pain that accompanies them. Given the massive scale of the problem, there's a growing movement in dentistry to treat cavities without drilling and filling them.

Extreme instances of stress can cause lasting changes to the brain itself. This could leave some people more vulnerable to addiction, a University of Mississippi study concludes.

QIMR Berghofer has unveiled the next-generation of its world-leading melanoma risk prediction calculator to better help Australians take action against one of the country's most deadly, costly, and common cancers that claims more lives each year than the national road toll.

The cell nucleus goes a long way during an immune response, both literally and figuratively.

For over two decades, finasteride—a popular prescription drug taken by millions of men to treat hair loss—has quietly carried a shadow. Behind its cosmetic promise lay disturbing signs of deeper harm: depression, anxiety, and in some cases, suicide.

The new Nordic dietary guidelines, which consider both our health and the health of the planet, are associated with longer life, according to a new study from Aarhus University.

Parkinson's disease causes both movement and cognitive deficits, and for a long time both were thought to be caused by the accumulation of a protein called alpha-synuclein in the brain. But a new Nature Communications study has found that the cognitive deficits arise through a different—and unexpected—mechanism.
