Incidence of out-of-hospital cardiac arrest on a postholiday weekday

JAMA Network Open

2026-03-06

(Press-News.org) About The Study: In this nationwide cohort study, a postholiday weekday was associated with a significantly elevated out-of-hospital cardiac arrest incidence in South Korea, particularly after consecutive rest days and among vulnerable populations. These findings support enhanced emergency medical services preparedness, targeted public health messaging during holiday periods, and evaluation of preventive interventions for high-risk populations during postholiday transitions.

Prior authorization bans for buprenorphine alone may not improve treatment retention

2026-03-06

State laws that ban insurance prior authorization for buprenorphine—a leading medication for opioid use disorder—may not help more patients stay in treatment for the recommended minimum of 180 days, Weill Cornell Medicine researchers report. Though prescription buprenorphine can be a life-saving treatment that relieves opioid cravings and withdrawal symptoms, adherence to the medication is low. Published Mar. 6 in JAMA Health Forum, the study examined whether state laws prohibiting private insurance plans from requiring prior authorization improved treatment retention, which is essential for reducing relapse, overdose risk and death. While the 2023–2024 ...

When light boosts protein evolution

2026-03-06

Evolution is biology’s powerful method of engineering. It works by generating many variants of DNA, RNA, and proteins inside cells and letting nature “select” the organism that performs best. Early farmers started taking advantage of evolution by interfering with natural selection and letting only the most productive livestock and crops mate. In laboratories, researchers developed methods for directed evolution of proteins, especially enzymes and antibodies, that are used in household ...

New model may predict preeclampsia in late pregnancy

2026-03-06

A machine-learning model developed by Weill Cornell Medicine investigators may provide clinicians with an early warning of a complication that can occur late in pregnancy. Preeclampsia is a sudden onset condition that involves high blood pressure prior to delivery. It affects about 2% to 8% of pregnancies worldwide and can have serious consequences for both parent and child. A new study, published March 6 in JAMA Network Open, describes a machine-learning-based computer model that provides continually updated predictions of preeclampsia risk based on electronic health record data recorded late in pregnancy. ...

Lifestyle medicine experts call meaning, purpose, and spirituality foundational to evidence-based, whole-person lifestyle change

2026-03-06

A new peer-reviewed paper calls for meaning, purpose, and spirituality to be treated as core components of lifestyle medicine — not optional add-ons — because they directly influence patients’ ability to adopt and sustain health-promoting behaviors. The paper, “Meaning, Purpose, and Spirituality in the Clinical Practice of Lifestyle Medicine,” emerged from a 2025 national summit convened by the American College of Lifestyle Medicine (ACLM) in collaboration with the Global Positive Health Institute and funded by the Ardmore Institute of Health. The summit brought together nearly 100 experts ...

Significant acceleration of global warming since 2015

2026-03-06

Global warming has accelerated since 2015, according to a new study by the Potsdam Institute for Climate Impact Research (PIK). After accounting for known natural influences on global temperature, the research team detected a statistically significant acceleration of the warming trend for the first time. Over the past ten years, the estimated warming rate has been around 0.35°C per decade, depending on the dataset, compared with just under 0.2°C per decade on average from 1970 to 2015. This recent rate ...

FAU awarded $2.4M NIH grant to study immune signaling and social behavior

2026-03-06

Florida Atlantic University has received a $2.4 million grant from the National Institutes of Health to investigate how an immune-related receptor in neurons plays a fundamental role in brain function, behavior and psychiatric health. The award, funded by the NIH’s National Institute of Neurological Disorders and Stroke, supports groundbreaking research that challenges long-standing assumptions about how the brain works. Led by Ning Quan, Ph.D., principal investigator, a professor in the Department of Biomedical Science within FAU’s Charles E. Schmidt College of Medicine, and a member of the FAU Stiles-Nicholson Brain Institute, the project focuses on a receptor ...

Deep learning-enabled virtual multiplexed immunostaining of label-free tissue for vascular invasion assessment

2026-03-06

In a groundbreaking study published in BME Frontiers, researchers from the University of California, Los Angeles (UCLA), in collaboration with international partners, have developed a deep learning-based virtual multiplexed immunostaining (mIHC) method. This novel approach enables the simultaneous generation of ERG, PanCK, and H&E images from label-free tissue sections, significantly enhancing the accuracy and efficiency of vascular invasion assessment in thyroid cancer. Traditional immunohistochemistry (IHC) techniques, which are pivotal in diagnosing various cancers, ...

New PET imaging study reveals how ketamine relieves treatment-resistant depression

2026-03-06

Major depressive disorder (MDD) is one of the leading causes of disability worldwide, and approximately 30% of patients develop treatment-resistant depression (TRD), a condition that does not respond adequately to conventional antidepressant therapies. Although ketamine has emerged as a rapid-acting antidepressant for individuals with TRD, its underlying biological mechanism in the human brain has remained poorly understood, limiting efforts to optimize and personalize treatment. In a new study published in the journal Molecular Psychiatry on March 05, 2026, a research team led by Professor Takuya Takahashi from the Department ...

New study reveals differences between anime bamboo muzzle and actual bamboo

2026-03-06

In storytelling, even small visual details can become unforgettable. In the globally popular anime Demon Slayer, one such detail is the short bamboo muzzle worn by a central character. It looks simple and believable, just a piece of green bamboo tied across the mouth. But a new scientific study suggests that this familiar object could not exist in nature as shown in the anime. To investigate this, Professor Akio Inoue from the Faculty of Agriculture and Agricultural Technology and Innovation Research Institute, Kindai University, Japan, compared anime illustrations showing the bamboo muzzle with the structure of real bamboo. The ...
