JAMA Network Open

2025-03-12

(Press-News.org) About The Study: This cohort study found that healthier diets and lower waist to hip ratio throughout midlife were associated with better brain and cognitive health in older age. The findings suggest that interventions to improve diet and manage central obesity might be most effective between ages 48 and 70.

Evolution and current challenges of gastrointestinal endoscopy in Nigeria: insights from a nationwide survey

2025-03-12

Background and objectives Gastrointestinal endoscopy has revolutionized the entire practice of gastroenterology worldwide, including Nigeria. Endoscopy was introduced in Nigeria more than four decades ago, and it has been a story of varying successes and challenges. This study explored the various experiences of endoscopists, the challenges they face, and the efforts put in place to maintain the practice in Nigeria. Methods This cross-sectional survey was conducted from October to December 2023 among endoscopists practicing ...

Transgender and gender diverse people less likely to receive follow-up after a mental health hospitalization

2025-03-12

Toronto, ON, March 12, 2025—Transgender and gender diverse individuals who were hospitalized for psychiatric care were less likely to have a follow-up visit compared to the general population, suggesting they face transphobia in the hospital system. In a new study from ICES and the Centre for Addiction and Mental Health (CAMH), findings demonstrate that transgender and gender diverse (TGD) people face an interesting paradox: they have lower access to appropriate mental health care and support following a psychiatric hospitalization, yet have better follow-up after an emergency department (ED) visit. According to Statistics Canada, TGD people account ...

Long-lived families show lower risk for peripheral artery disease

2025-03-12

“Notably, the findings from this work may provide novel insight into the underlying mechanisms of PAD and, perhaps, have prevention or therapeutic impacts.” BUFFALO, NY — March 12, 2025 — A new research paper was published in Aging (Aging-US) on February 25, 2025, Volume 17, Issue 2, titled “Epidemiology and genetic determination of measures of peripheral vascular health in the Long Life Family Study.” Researchers from multiple institutions, led by first author and corresponding author ...

Food systems, climate change, and air pollution: Unveiling the interactions and solutions

2025-03-12

A recent review published in Engineering delves into the complex relationships among food systems, climate change, and air pollution, highlighting the need for sustainable strategies to address these interconnected global challenges. Climate change and air pollution pose significant threats to food systems. Rising temperatures, altered precipitation patterns, and extreme weather events, driven by climate change, disrupt agricultural production. For example, higher temperatures and shifting precipitation patterns have altered crop growth cycles, caused yield fluctuations, and increased uncertainty ...

Tissue engineering offers new hope for spinal cord injury repair

2025-03-12

A recent study published in the journal Engineering delves into the application of tissue engineering in spinal cord injury (SCI) repair, presenting a comprehensive review of the latest research and potential treatment strategies. SCI is a severe condition that affects the central nervous system, often leading to permanent loss of sensation and motor function. Current treatments, such as surgical decompression and drug therapy, can only alleviate symptoms to a certain extent, making it crucial to explore new therapeutic approaches. Tissue engineering, an interdisciplinary field integrating life science, material science, engineering technology, ...

Preclinical study finds earlier ACL reconstruction is associated with lower risk of knee osteoarthritis

2025-03-12

A preclinical study by HSS investigators found that earlier anterior cruciate ligament (ACL) reconstruction led to lower immune cell activity, less inflammation and fewer joint changes associated with knee osteoarthritis compared to delayed surgery. The research team shared their study results today in a poster presentation at the American Academy of Orthopaedic Surgeons 2025 Annual Meeting. After a knee injury, such as an ACL tear or rupture, immune cells travel to lymph nodes, where they interact with ...

Assessing pain, anxiety and other symptoms of nursing home residents unable to speak for themselves

2025-03-12

INDIANAPOLIS – As many as half of nursing home residents are cognitively impaired and may be unable to communicate symptoms such as pain or anxiety to the staff and clinicians caring for them. Therefore, information needed for the evaluation of symptoms and subsequent treatment decisions typically does not reliably exist in nursing home electronic health records (EHRs). A new paper reports on the novel adaptation of a commonly used symptom assessment instrument to more comprehensively acquire this difficult-to-obtain data with the ultimate goal of enabling knowledge-based expansion of palliative care services in nursing homes ...

Thirty-three centers join new Bronchiectasis and NTM Care Center Network

2025-03-12

Miami (March 12, 2025) – The Bronchiectasis and NTM Association has accepted 27 Care Center and six Clinical Associate Center sites in 23 states and the District of Columbia into the new Bronchiectasis and NTM Care Center Network (CCN). The CCN aims to facilitate access to specialized care and support for the hundreds of thousands of people with bronchiectasis and nontuberculous mycobacterial (NTM) lung disease. “As the prevalence of bronchiectasis and NTM lung disease grows, it is even more important for us to create this Care Center Network to improve ...

Effects of ethanol on the digestive system

2025-03-12

Excessive alcohol consumption is a significant public health concern, responsible for approximately 6% of all deaths and contributing to 5.1% of the global disease burden. Alcohol use is a major risk factor for over 200 diseases, including liver cirrhosis, pancreatitis, and esophageal cancer, with a particularly high incidence of gastrointestinal diseases. More than 50% of alcohol-related deaths are caused by gastrointestinal diseases, highlighting the importance of understanding how ethanol affects the digestive system. This review aims to provide an overview of ethanol ...

KIER unveils blueprint for cost-effective production of eco-friendly green hydrogen

2025-03-12

Dr. Joungho Park and his research team from the Energy AI and Computational Science Laboratory at the Korea Institute of Energy Research (KIER) have conducted an economic analysis of water electrolysis, a key technology for future eco-friendly hydrogen production, and presented optimal operation strategies to maximize efficiency and reduce costs. Green hydrogen, considered a key eco-friendly fuel of the future, is primarily produced using two technologies: alkaline water electrolysis and proton exchange membrane (PEM) water electrolysis. Among ...
