JAMA Health Forum

2024-03-01

(Press-News.org) About The Study: The results of this study highlight how rates of recurring and chronic food insecurity among families with older adults rose substantially over the past 20 years. Monitoring national trends in food insecurity among older adults has direct programmatic and policy implications.

Self-reported everyday functioning after COVID-19 infection

2024-03-01

About The Study: The findings of this study of 372 veterans suggest that the negative impacts of the COVID-19 pandemic on everyday function may occur via multiple pathways regardless of whether or not they had a documented infection with COVID-19. Future work with larger samples is needed to validate the estimated associations. Authors: Theodore J. Iwashyna, M.D., Ph.D., of Ann Arbor VA in Ann Arbor, Michigan, is the corresponding author.

The surprisingly complex inner workings of an endocrine tumor

2024-03-01

Researchers from Tokyo Medical and Dental University (TMDU) find that the cells that make up aldosterone-producing adenomas become more transcriptionally active and express higher levels of genes linked to hormone production over intratumoral differentiation. Tokyo, Japan – There is strength in teamwork, and it turns out that this applies to tumors, too. Researchers from Japan have reported that different types of cells within a single benign tumor may work together to promote the tumor’s growth. In a study published this ...

Safety assessments for older drivers would benefit from introducing spatial orientation tests

2024-03-01

Older drivers who have worse spatial orientation ability experience greater difficulty when making turns across oncoming traffic, according to new research from the University of East Anglia (UEA). Spatial orientation skills are the combination of skills that enable us to mentally determine our position, or the position of our vehicle and other vehicles, relative to the environment. Lead author Sol Morrissey, a PhD researcher at UEA’s Norwich Medical School, said: “Driving safety is typically reduced in older adults due to changes that take place during ...

New type of metallacrown ether, polyoxometalatocrown ether, opens research opportunities

2024-03-01

Crown ethers were discovered in 1967. They were then modified by adding a metal-containing unit creating metallacrown ethers. These metallacrown ethers have been the subject of intensive research. Depending on the molecular makeup of the metallacrown ethers and their resultant architecture, the properties and therefore the uses of the metallacrowns can change. They have many different uses currently, and ongoing studies continue to expand their application. Just a few of these include magnetic refrigeration, imaging agents—specifically as potential contrast agents in magnetic resonance imaging—and single-molecular ...

A protective human monoclonal antibody targeting a conserved site of spike glycoprotein of SARS-CoV-2 Omicron variants

2024-03-01

The ongoing COVID-19 pandemic caused by SARS-CoV-2 has caused serious damage to public health and the global economy, and one strategy to combat COVID-19 has been the development of broadly neutralizing antibodies for prophylactic and therapeutic use. The most emergency-use authorized (EUA) therapeutic monoclonal antibodies, are more likely to lose their neutralizing activities as the viral epitopes (e.g. the receptor-binding domain, RBD) within spike protein of SARS-CoV-2 they target are more prone to mutate. By contrast, the S2 subunit of spike protein, has a much lower frequency of mutation than ...

Scientists reveal how our cells’ leaky batteries are making us sick

2024-03-01

Researchers have discovered how “leaky” mitochondria – the powerhouses of our cells – can drive harmful inflammation responsible for diseases such as lupus and rheumatoid arthritis. Scientists may be able to leverage the findings to develop better treatments for those diseases, improve our ability to fight off viruses and even slow aging. The new discovery reveals how genetic material can escape from our cellular batteries, known as mitochondria, and prompt the body to launch a damaging immune response. By developing therapies to target this process, doctors may one day be able to stop the harmful inflammation ...

Ultraviolet radiation from massive stars shapes planetary systems

2024-03-01

To find out how planetary systems such as our Solar System form, an international research team including scientists from the University of Cologne studied a stellar nursery, the Orion Nebula, using the James Webb Space Telescope (JWST). By observing a protoplanetary disc named d203-506, they discovered the key role massive stars play in the formation of planetary systems that are less than a million years old. The study, led by Dr Olivier Berné from the National Centre for Scientific Research (CNRS) ...

Can a purposeful walk intervention with a distance goal using an activity monitor improve individuals' daily activity and function post total hip replacement surgery? A randomized pilot trial

2024-03-01

A research paper by scientists at Bournemouth University proposed a randomized pilot trial, which aimed to determine the eﬀect of an intervention where outdoor walking distance is used as a goal to increase daily activity of older adults using a commercial activity monitor at 3 to 6 months post total hip replacement (THR). The new research paper, published on Nov. 30 in the journal Cyborg and Bionic Systems, indicated the participants in the intervention group had higher activity levels after THR, compared to those in the control group. The Cohen’s eﬀect ...

Supramolecule combination of fullerene and metalloporphyrin improves zinc-air battery function

2024-03-01

Zinc-air batteries are an inexpensive, powerful battery alternative that can be used on the small scale to power electronics or on the large scale for electric vehicles or energy storage. These batteries work when oxygen from the air oxidizes zinc, but the difficulty in oxygen activation which degrades battery performance has prevented their wide commercial adoption. Information presented in a paper published in Carbon Future on 19 January shows how fullerene- metalloporphyrin derived carbon materials as catalysts can improve the performance and stability of zinc-air batteries. “The sluggish kinetic characteristics caused by the difficulty ...

BPA exposure linked to gut microbiota, childhood obesity in new study

2024-03-01

Highlights: A chemical called Bisphenol A (BPA) is used to make many durable plastics and resins. Previous studies suggest high BPA exposure can increase health risks and change gut microbiome structure. Researchers investigated links between BPA exposure, obesity and the gut microbiome. The study found that normal-weight children had more unique bacteria taxa, which may help degrade BPA. The findings may help point to microbial strains that neutralize BPA in the gut. Washington, D.C. — March 1, 2024 — A synthetic chemical called Bisphenol A, or BPA, is widely used in the production of durable plastic products including eyewear, ...
