Intersectional Racial and Sex Disparities in Unintentional Overdose Mortality

JAMA Network Open

2025-04-01

(Press-News.org) About The Study: In this cross-sectional study of overdose deaths, disparities in overdose mortality were evident, with Black men and Black women experiencing a pronounced and increasing burden of mortality compared with their white counterparts. Addressing these disparities will require a multipronged approach targeting the social, physical, economic, and policy risk environments.

PLOS announces new partnership in China

2025-04-01

San Francisco, California, United States - The Public Library of Science (PLOS) and the Society of China University Journals (CUJS) today announced a 3-year strategic partnership between the organizations to work together on topics and content related to open access, open science, scientific integrity and scientific evaluation. CUJS is an academic, national and non-profit social organization with more than 1,200 journal members. The organization conducts academic research and training programs in the editing and publishing of STM journals and promotes the development of STM ...

New options for controlling type 2 diabetes

2025-04-01

Nearly 40% of patients diagnosed with type 2 diabetes imperil their health by stopping their medication within the first year, UVA Health diabetes experts note in a new paper highlighting a growing array of treatment options. The pragmatic new paper urges doctors to consider not just traditional diabetes medicines but emerging alternatives that patients may be more likely to stick with long-term. “Prescribing a medication or making lifestyle recommendations that a patient is not willing or able to follow for any reason is not likely to lead to improvements ...

Senolytics target Alzheimer’s-linked brain enzymes without harming healthy ones

2025-04-01

“This work provides new opportunities for the development of the next generation of ChE inhibitors that specifically target AChE and BChE associated with AD pathology.” BUFFALO, NY — April 1, 2025 — A new research paper was published in Aging (Aging-US) on March 29, 2025, as the cover of Volume 17, Issue 3, titled “Differential senolytic inhibition of normal versus Aβ-associated cholinesterases: implications in aging and Alzheimer’s disease.” In this study, a research team from Dalhousie University, led by Sultan Darvesh, discovered that certain anti-aging ...

An immune cell may explain how maternal inflammation causes neurodevelopmental disorder

2025-04-01

A research group led by Nagoya University Graduate School of Medicine in Japan has uncovered a potential mechanism linking maternal inflammation to delayed neurodevelopment in infants. The research suggests the role of CD11c-positive microglia—immune cells in the brain crucial for myelination—during infant brain development. The results, published in Communications Biology, suggest new strategies to mitigate the long-term neurodevelopmental effects of maternal inflammation. Inflammation during pregnancy occurs when the mother’s immune system becomes activated during pregnancy, typically due to an infection, autoimmune response, or environmental factors. ...

New study refocuses research on mysterious falcon decline

2025-04-01

North America’s smallest falcon, the American Kestrel (Falco sparverius), has declined across the continent since the 1970s, yet the causes continue to stump raptor biologists. A new study published in the Journal of Raptor Research adds a piece to the puzzle with the discovery that in the Northeast, where declines are most alarming, fledglings demonstrate a relatively high survival rate. This paper, titled “Juvenile and Adult Survival Estimates of American Kestrels Throughout the Full Annual Cycle in Eastern North America,” is the first of its kind. No other study has assessed winter survival ...

Omega-6 fatty acid promotes the growth of an aggressive type of breast cancer

2025-04-01

Linoleic acid, an omega-6 fatty acid found in seed oils such as soybean and safflower oil, and animal products including pork and eggs, specifically enhances the growth of the hard-to-treat “triple negative” breast cancer subtype, according to a preclinical study led by Weill Cornell Medicine investigators. The discovery could lead to new dietary and pharmaceutical strategies against breast and other cancers. In the study, published March 14 in Science, the researchers found that linoleic acid can activate a major growth pathway in tumor cells by binding to a protein called FABP5. Comparing breast cancer subtypes, the team observed that this growth pathway activation ...

FAU secures $1.3 million NIH grant for breakthrough in HIV self-test technology

2025-04-01

As of the end of 2023, nearly 40 million people worldwide were living with HIV, including approximately 1.2 million in the United States. In the same year, about 630,000 people globally died from AIDS-related illnesses. Although this is a significant decline from previous years, AIDS-related deaths remain a critical global health challenge. While antiretroviral therapy (ART) has improved the life expectancy of people with AIDS, a lack of effective diagnostics and disease management tools has hindered its global implementation. Only 59% of those in need have access to treatment, and about one in four people living with HIV are unaware of their status. Additionally, ...

Study finds higher cardiac deaths in combined day-night heatwaves

2025-04-01

Cardiac deaths increase significantly during compound heatwaves—heatwaves where temperatures are elevated both during the day and overnight—according to a new study in JACC, the flagship journal of the American College of Cardiology. The study also found that some types of heart disease are more sensitive to heatwaves than others and that different types of heatwaves may impact heart health in distinct, nonlinear ways. The research highlights the special risks of compound heatwaves ...

NYC, Baltimore research scientists receive grants to study cardiovascular/diabetes connection

2025-04-01

DALLAS, April 1, 2025 — A New York City-based physician scientist who explores ways to improve health by looking at the ways in which cells and molecules impact disease and an epidemiologist from Baltimore who has devoted her career to identifying ways to improve screening, diagnosis and patient care for people with diabetes are the most recent American Heart Association Merit Award recipients. Over the next five years, each researcher will receive a total of $1 million in funding from the Association, a global force changing the future of health for all. The American Heart Association’s Merit Award is one of ...

AI propaganda: prolific and persuasive

2025-04-01

A study of the use of AI by a Russian-backed propaganda outlet shows how AI allows propagandists to increase their production capacity without any loss in persuasive power. In December 2023, journalists at the BBC and Clemson University’s Media Forensics Hub published an investigation revealing that the site DCWeekly.org was a Russian propaganda outlet, part of a broader network disseminating pro-Kremlin and anti-Ukrainian narratives. Morgan Wack and colleagues found that prior to September 20, 2023, much of the content on the site was simply lifted from other right-leaning outlets. After that date, however, the stories were generally rewritten by AI, allowing the site to use a broader ...
