Interpreting population mean treatment effects in the Kansas City Cardiomyopathy Questionnaire

JAMA Cardiology

2024-11-15

(Press-News.org) About The Study: Inferences about clinical impacts based on population-level mean treatment effects may be misleading, since even small between-group differences may reflect clinically important treatment benefits for individual patients. Results of this study suggest that clinical trials should explicitly describe the distributions of Kansas City Cardiomyopathy Questionnaire change at the patient level within treatment groups to support the clinical interpretation of their results.

Targeting carbohydrate metabolism in colorectal cancer: Synergy of therapies

2024-11-15

“This commentary will discuss what is known about such combinatorial treatments, including potential mechanisms and future protocols.” BUFFALO, NY- November 15, 2024 – A new review was published in Volume 11 of Oncoscience on November 12, 2024, entitled, “Targeting carbohydrate metabolism in colorectal cancer - synergy between DNA-damaging agents, cannabinoids, and intermittent serum starvation.” As highlighted by the authors in the abstract of this review, chemotherapy is a common treatment for many cancers. However, it is often ineffective for long-term patient survival and ...

Stress makes mice’s memories less specific

2024-11-15

Stress is a double-edged sword when it comes to memory: stressful or otherwise emotional events are usually more memorable, but stress can also make it harder for us to retrieve memories. In PTSD and generalized anxiety disorder, overgeneralizing aversive memories results in an inability to discriminate between dangerous and safe stimuli. However, until now, it wasn’t clear whether stress played a role in memory generalization. Now, neuroscientists report November 15 in the Cell Press journal Cell that acute stress prevents mice from forming specific memories. Instead, the stressed mice formed generalized memories, which are ...

Research finds no significant negative impact of repealing a Depression-era law allowing companies to pay workers with disabilities below minimum wage

2024-11-15

PHILADELPHIA—Debate continues to swirl nationally on the fate of a practice born of an 86-year-old federal statute allowing companies to pay workers with disabilities subminimum wages: anything below the federal minimum wage of $7.25 an hour, but for some roles as little as 25-cents-per-hour. Those in favor of repealing this statute highlight assumptions about reduced productivity along with the unfairness of this wage level—often used elsewhere to pay, for example, food service workers who typically make additional wages in tips. Those against repeal have voiced concerns that, without subminimum ...

Resilience index needed to keep us within planet’s ‘safe operating space’

2024-11-15

EMBARGOED: NOT FOR RELEASE UNTIL FRIDAY 15 NOVEMBER 2024 AT 11:00 ET (15:00 UK TIME). Researchers are calling for a ‘resilience index’ to be used as an indicator of policy success instead of the current focus on GDP. They say that GDP ignores the wider implications of development and provides no information on our ability to live within our planet’s ‘safe operating space’. In a paper published today [15 November] in the journal One Earth, researchers from the University of Southampton, UCL ...

How stress is fundamentally changing our memories

2024-11-15

Researchers at The Hospital for Sick Children (SickKids) have uncovered that stress changes how our brain encodes and retrieves aversive memories, and discovered a promising new way to restore appropriate memory specificity in people with post-traumatic stress disorder (PTSD). If you stumble during a presentation, you might feel stressed the next time you have to present because your brain associates your next presentation with that one poor and aversive experience. This type of stress is tied to one memory. But stress from traumatic events ...

Time in nature benefits children with mental health difficulties: study

2024-11-15

A team of researchers from McGill and Université de Montréal’s Observatoire pour l’éducation et la santé des enfants (OPES, or observatory on children’s health and eduation), led by Sylvana Côté, found that spending two hours a week of class time in a natural environment can reduce emotional distress among 10- to 12-year-olds who had the most significant mental health problems before the program began. The research comes on the heels of the publication of a UNICEF ...

In vitro model enables study of age-specific responses to COVID mRNA vaccines

2024-11-15

mRNA vaccines saved lives during the COVID-19 pandemic, but older people had less of an immune response to the vaccines than did younger adults. Why? Boston Children’s researchers, led by Byron Brook, PhD, and Ofer Levy, MD, PhD, have found some answers, while providing proof-of-concept of a new system that can model vaccine responses in a dish. The test system, described in a paper out today in iScience, is called MEMPHIS (Modular Evaluation of immunogenicity using Multi-Platform Human In vitro Systems). It analyzes whole human blood from people of different age groups and applies both proteomics and targeted assays to measure ...

Sitting too long can harm heart health, even for active people

2024-11-15

More time spent sitting, reclining or lying down during the day may increase the risk of cardiovascular disease (CVD) and death, according to a study in JACC, the flagship journal of the American College of Cardiology, and presented at the American Heart Association’s Scientific Sessions 2024. More than roughly 10-and-a-half hours of sedentary behavior per day was significantly linked with future heart failure (HF) and cardiovascular (CV) death, even among people meeting recommended levels of exercise. “Our findings support cutting back on sedentary time to reduce cardiovascular risk, with 10.6 hours a day marking a potentially key threshold ...

International cancer organizations present collaborative work during oncology event in China

XI’AN, CHINA [November 15, 2024] — The National Comprehensive Cancer Network® (NCCN®)—an alliance of leading cancer centers in the United States—is taking part in the Fourth International Congress of the Asian Oncology Society and the Chinese Congress on Holistic Integrative Oncology (2024 CCHIO) sponsored by the China Anti-Cancer Association (CACA), Chinese Institute of Development Strategy on Holistic Integrative Medicine, and Asian Oncology Society (AOS). The three-day event highlights international collaborations to improve cancer treatment and outcomes across China and beyond. “NCCN ...

One or many? Exploring the population groups of the largest animal on Earth

2024-11-15

FROM: James Urton University of Washington 206-543-2580 jurton@uw.edu (Note: researcher contact information at the end) Hunted nearly to extinction during 20th century whaling, the Antarctic blue whale, the world’s largest animal, went from a population size of roughly 200,000 to little more than 300. The most recent estimate in 2004 put Antarctic blue whales at less than 1% of their pre-whaling levels. But is this population recovering? Is there just one population of Antarctic blue whales, or multiple? Do these questions matter for conservation? A team led by Zoe Rand, a University of Washington doctoral student, tackles these questions ...
