Fine particulate matter from 2020 California wildfires and mental health–related emergency department visits

JAMA Network Open

2025-04-04

(Press-News.org) About The Study: Wildfire smoke exposure was associated with significantly increased odds of subsequent emergency department visits for mental health conditions in this cross-sectional study, with varying lag times for different subconditions and demographic groups. Health care professionals and systems should prepare for a possible increase in demand for mental health–related emergency services during wildfire events.

Gender inequity in institutional leadership roles in US academic medical centers

2025-04-04

About The Study: This systematic scoping review suggests that even though emphasis has been placed on addressing gender inequities in academic medicine, considerable disparities remain at the leadership level. While certain positions and specialties have been observed to have more female leaders, niches of academic medicine almost or completely exclude women from their leadership ranks. Importantly, even female-dominated specialties, such as obstetrics and gynecology, have substantial inequity in leadership roles. It is past time for organizational and systems-level changes to ensure equitable ...

Pancreatic cells ‘remember’ epigenetic precancerous marks without genetic sequence mutations

2025-04-04

FOR IMMEDIATE RELEASE Johns Hopkins Medicine scientists say they have found a pattern of so-called epigenetic “marks” in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a temporary “memory” of those cancer-linked marks. Epigenetic marks are chemical modifications that help regulate genetic expression without directly altering DNA sequence in the makeup of genes. While the genetic code is like a computer’s hardware, epigenetics involves chemical marks on top of the genetic code that act as software programing in a computer. The ...

Rare combination of ovarian tumors found in one patient

2025-04-04

“This case underscores the rare coexistence of serous cystadenofibroma in one ovary and collision features involving serous and mucinous cysts in the contralateral ovary, a combination scarcely reported in the literature.” BUFFALO, NY — April 4, 2025— A new case report was published in Oncoscience’s Volume 12 on March 31, 2025, titled “Cystadenofibroma and contralateral collision lesions: A unique ovarian case report.” Authored by Dr. Naina Kumar and colleagues from the All India Institute of Medical Sciences, the report presents a highly unusual case involving two different types of benign ovarian tumors in ...

Artificial intelligence has potential to aid physician decisions during virtual urgent care

2025-04-04

Do physicians or artificial intelligence (AI) offer better treatment recommendations for patients examined through a virtual urgent care setting? A new Cedars-Sinai study shows physicians and AI models have distinct strengths. The late-breaking study presented at the American College of Physicians Internal Medicine Meeting and published simultaneously in the Annals of Internal Medicine compared initial AI treatment recommendations to final recommendations of physicians who had access to the AI recommendations but may or ...

New study reveals polymers with flawed fillers boost heat transfer in plastics

2025-04-04

New Study Reveals Polymers with Flawed Fillers Boost Heat Transfer in Plastics The UMass Amherst-led team challenges the conventional wisdom that perfect fillers are better for making thermally conductive polymers AMHERST, Mass. — In the quest to design the next generation of materials for modern devices – ones that are lightweight, flexible and excellent at dissipating heat – a team of researchers led by the University of Massachusetts Amherst made a discovery: imperfection has its upsides. This research, published in Science Advances, ...

Signs identified that precede sudden arrhythmic death syndrome in young people

2025-04-04

Milan, Italy – 4 April 2025. Recognising and detecting the signs that commonly precede sudden arrhythmic death syndrome (SADS) may help to prevent premature deaths, according to research presented today at ESC Preventive Cardiology 2025,1 a scientific congress of the European Society of Cardiology (ESC). “SADS has not been well evaluated despite being one of the most common underlying causes of sudden cardiac death in young people, including young athletes,” said study author Dr. Matilda Frisk Torell of Sahlgrenska Academy - University of Gothenburg, Sweden. “We conducted an analysis of a large cohort of cases of sudden cardiac death in Sweden to ...

Discovery of bacteria's defence against viruses becomes a piece of the puzzle against resistance

2025-04-04

Antibiotic resistance is a global health challenge that could overtake cancer mortality within a few decades. In a new study, researchers at Umeå University, Sweden, show that the emergence of resistance can be understood in the mechanism of how bacteria build up defences against being infected by viruses. It is about genes in the bacterium that interfere with the attacking virus's ability to multiply. "A key to antibiotic resistance might be the use of viruses to kill bacteria, however, the systems that bacteria employ to defence themselves against viruses are unknown. Understanding these ...

Pre-eclampsia is associated with earlier onset and higher incidence of cardiovascular risk factors

2025-04-04

Milan, Italy – 4 April 2025. Women who have experienced pre-eclampsia have accelerated accumulation of cardiovascular (CV) risk factors compared with women who had pregnancies without pre-eclampsia according to research presented today at ESC Preventive Cardiology 2025,1 a scientific congress of the European Society of Cardiology (ESC). Pre-eclampsia typically affects 2−5% of pregnant women and is broadly defined as the development of hypertension and high protein levels in the urine of a woman with previously normal blood pressure.2 ...
