Stroke risk linked to both too little and too much sleep

Researchers investigated the link between sleep problems and stroke risk. They found that sleep problems increased stroke incidence by as much as five times. Further studies are needed to confirm the results. Quality sleep is essential for health. Sleep problems range from too short or too long sleep duration, difficulty falling and staying asleep, and

New Medicare Rule Streamlines Prior Auth in MA Plans

A new federal rule seeks to reduce Medicare Advantage insurance plans’ prior authorization burdens on physicians while also ensuring that enrollees have the same access to necessary care that they would receive under traditional fee-for-service Medicare. The prior authorization changes, announced this week, are part of the Centers for Medicare & Medicaid Services’ (CMS’) 2024

How the brain slows down when we focus our gaze

Changing between slow and fast integration of information, the brain can flexibly modulate the timescales on which it operates. This is the result of a new study by an international team of researchers, now published in the journal Nature Communications. Their analysis of experimental data from the visual cortex and their computer simulations also provide

Researchers tackle major obstacle to stem-cell heart repair

Researchers at the University of Washington School of Medicine in Seattle have engineered stem cells that do not generate dangerous arrhythmias, a complication that has to date thwarted efforts to develop stem-cell therapies for injured hearts. “We have found what we have to tackle to make these cells safe,” said Silvia Marchiano, a postdoctoral fellow

Japanese survey: Is the information on infection prevention measures against COVID-19 reaching the target audience?

Key points: Information on infection prevention measures against COVID-19 pandemic disseminated by various media may not be sufficiently reaching the target audience seeking to obtain information. Television was the most common source of information among eating and drinking services at Ota, with the rate of use exceeding that of guidelines (Fig. 1). Issues such as

Tool targets cancer-causing fusions’ weak spot

Scientists at St. Jude Children’s Research Hospital comprehensively characterized oncogenic fusions in pediatric cancer, providing proof-of-principle for genetic engineering-based therapies. The scientific foundation needed to work on curing a class of cancer-causing mutations is here, in the form of a tool from St. Jude Children’s Research Hospital. Computational biologists at St. Jude comprehensively categorized and

Covid infection could speed up progression of dementia

What is Alzheimer's disease? In the early days of the pandemic not a huge amount was understood about the Covid virus. Most people were aware of the common symptoms experienced when infected but that was about it. Since then scientists are continuing to uncover more about what some of the long-term effects of the virus

Biological markers identified as powerful predictors of prostate cancer relapse following radiotherapy

Two key proteins linked to cell division can reliably predict disease recurrence in prostate cancer after radiotherapy treatment, according to new research. Using an inexpensive and widely available technique in the clinic, the researchers evaluated a range of proteins in prostate tumor biopsies and determined that the phosphatase and tensin homolog (PTEN) and geminin proteins

Infertility affects one in six: WHO

Around one in every six adults experiences infertility, the World Health Organization estimated Tuesday as it called for an urgent increase in access to fertility care. The WHO determined that around 17.5 percent of adults worldwide are affected by infertility at some point, and found little variation between regions and wealthy and poorer countries. “Globally,

CDC investigating salmonella outbreak linked to flour

U.S. health officials are investigating a Salmonella Infantis outbreak that is likely linked to raw flour. It’s not clear what brand of flour is the culprit. Investigators from the U.S. Centers for Disease Control and Prevention and Food and Drug Administration have identified 12 illnesses and three hospitalizations occurring across 11 states. Reported illnesses started

Lorlatinib found to be safe and effective for patients with ALK-driven relapsed/refractory high-risk neuroblastoma

In a significant step for the treatment of neuroblastoma, an international group of researchers led by Children’s Hospital of Philadelphia (CHOP), Winship Cancer Institute of Emory University and the New Approaches to Neuroblastoma Therapy (NANT) Consortium has shown that the targeted therapy lorlatinib is safe and effective in treating high-risk neuroblastoma. The findings, published today
