Accelerometer-measured physical activity, sedentary time, and heart failure risk in older women

JAMA Cardiology

2024-02-21

(Press-News.org) About The Study: The results of this study of 5,951 women ages 63 to 99 suggest that promoting regular physical activity and minimal sedentary time may be prudent for primary prevention of heart failure and its subtype with preserved ejection fraction for which treatment is limited.

Lifetime suicide attempts in otherwise psychiatrically healthy individuals

2024-02-21

About The Study: In this study using data from 1,948 U.S. adults with lifetime suicide attempts from a nationally representative population-based survey, an estimated 19.6% reported not having met criteria for any psychiatric disorders prior to their first attempt. This finding challenges clinical notions of who is at risk for suicidal behavior and raises questions about the safety of limiting suicide risk screening to psychiatric populations. Authors: Maria A. Oquendo, M.D., Ph.D., of the University of Pennsylvania in Philadelphia, is the corresponding author. To access the embargoed study: Visit our For The Media ...

Acupuncture for combat-related posttraumatic stress disorder

2024-02-21

About The Study: The acupuncture intervention used in this randomized clinical trial including 93 participants was clinically efficacious and favorably affected the psychobiology of posttraumatic stress disorder (PTSD) in combat veterans. These data build on extant literature and suggest that clinical implementation of acupuncture for PTSD, along with further research about comparative efficacy, durability, and mechanisms of effects, is warranted. Authors: Michael Hollifield, M.D., of the Tibor Rubin VA Medical Center in Long Beach, California, is the corresponding author.

Study finds high number of persistent COVID-19 infections in the general population

2024-02-21

New study finds that persistent COVID-19 infections are surprisingly common, with around one to three in every 100 infections lasting a month or longer. Some persistent infections had a high number of mutations, suggesting they could act as reservoirs to seed new variants of concern. People with persistent infections lasting for 30 days or longer were 55% more likely to report having Long Covid than people with more typical infections. Reinfections with the same variant were rare. A new study led by the University of Oxford has ...

Researchers reveal mechanism of drug reactivating tumor suppressors

2024-02-21

Researchers have revealed the mechanism of a drug shown to be effective in treating certain types of cancer, which targets a protein modification silencing the expression of multiple tumor suppressor genes. They also demonstrated in clinical trials the efficacy of the drug in reducing tumor growth in blood cancer. The findings could lead to longer-term treatments for the disease and therapies for other types of cancer with similar underlying causes. A team of researchers from the University of Tokyo and their collaborators focused on therapies targeting H3K27me3, a modification on a DNA-packaging histone protein, which plays a large role in regulating ...

UNC Lineberger named as a national research hub for NIH cancer screening study

2024-02-21

CHAPEL HILL, NC – UNC Lineberger Comprehensive Cancer Center has been selected as one of nine national research sites for the National Cancer Institute’s (NCI), part of the National Institutes of Health, newly launched Cancer Screening Research Network (CSRN), which will evaluate promising and emerging cancer screening technologies. Supporting the Biden-Harris Administration’s Cancer Moonshot initiative, the CSRN will conduct large, multi-center cancer screening studies with diverse populations in a variety of healthcare settings. The studies are designed to identify ...

New study suggests target steps per day for reduced risk of heart failure

2024-02-21

BUFFALO, N.Y. – The science is clear that movement is good for our bodies as we age. But just how much physical activity is beneficial for people over 60? A new study from the University at Buffalo provides an answer, and it’s not 10,000 steps per day. In fact, the study — published Feb. 21 in JAMA Cardiology — of nearly 6,000 U.S. women aged 63-99 reports that, on average, 3,600 steps per day at a normal pace was associated with a 26% lower risk of developing heart failure. The observational study from the Women’s Health Initiative ...

NIH launches research network to evaluate emerging cancer screening technologies

2024-02-21

The National Institutes of Health (NIH) has launched a clinical trials network to evaluate emerging technologies for cancer screening. The Cancer Screening Research Network (CSRN) will support the Biden-Harris administration’s Cancer Moonshot℠ by investigating how to identify cancers earlier, when they may be easier to treat. Eight groups have received funding from the National Cancer Institute (NCI), part of NIH, to carry out the initial activities of the network. “There are many cancers we still cannot reliably ...

Evidence review: Maternal mental conditions drive climbing death rate in U.S.

2024-02-21

WASHINGTON (Feb. 21, 2024) – Painting a sobering picture, a research team led by Children’s National Hospital culled years of data demonstrating that maternal mental illness is an under-recognized contributor to the death of new mothers. They are calling for urgent action to address this public health crisis in the latest edition of JAMA Psychiatry. Backed by dozens of peer-reviewed studies and health policy sources, the journal’s special communication comes as maternal mortality soars ...

Scientists from IOCB Prague have improved materials for reconstructive and plastic surgery

2024-02-21

Researchers from IOCB Prague and Ghent University have been working on improving the properties of gelatin-based materials, thereby expanding the possibilities of their use mainly in medicine. In a paper published in ACS Applied Engineering Materials, they have presented 3D-printable materials that can be easily monitored using an X-ray machine or through computed tomography (CT). Gelatin-based materials have been a hot topic of research in the last ten years because they are straightforward to produce, non-toxic, inexpensive, ...

Nanoscale manipulation of exciton–trion interconversion in a MoSe2 monolayer via tip-enhanced cavity-spectroscopy

2024-02-21

In a significant advancement for next-generation semiconductors, a collaborative research team, led by Professor Kyoung-Duck Park and Mingu Kang in the Department of Physics at POSTECH, Professor Yong Doug Suh in the Department of Chemistry at UNIST, who concurrently holds the position of Associate Director at the IBS Center for Multidimensional Carbon Materials (CMCM), and Professor Hyun Seok Lee in the Department of Physics at Chungbuk National University, has made groundbreaking discoveries in the field of two-dimensional (2D) semiconductors. Their findings, published in Nano Letters, shed light on the generation and control of trions, providing ...
