A UCSF telecare program that improves outcomes for patients with dementia and lightens the load for unpaid caregivers also has the surprising bonus of cutting Medicare costs, according to UC San Francisco research. In the study, publishing in JAMA Internal Medicine on Sept. 18, 2023, researchers, led by UCSF, compared the Medicare costs of 780 patients with dementia. The patients were randomized 2:1 to receive Care Ecosystem support – which included medical and practical assistance – or their usual care for a 12-month period. Both groups were similar in age, severity of dementia ...

Individuals with opioid use disorder who were prescribed a lower buprenorphine dose were 20% more likely to discontinue treatment than those on a higher dose, according to a study of patients prescribed buprenorphine in Rhode Island from 2016 to 2020, as fentanyl became widely available. The study, published today in JAMA Network Open, was supported by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, and conducted by researchers at Brown University, Providence, Rhode Island; NIDA and the Rhode Island ...

Plants produce an impressive array of metabolites, including many medically valuable steroids. Well-known examples of this class of substances obtained from plants are cardenolides. As early as 1785, the British physician William Withering (1741-1799) published a book on the red foxglove and its use in medicine (An account of the foxglove, and some of its medical uses: with practical remarks on dropsy, and other diseases. Birmingham 1785).  He had found out in experiments that taking extracts ...

Hospital staff spend a significant amount of time working to protect patients from acquiring infections while they are being cared for in the hospital. They employ various methods from hand hygiene to isolation rooms to rigorous environmental sanitation. Despite these efforts, hospital-onset infections still occur—the most common of which is caused by the bacterium Clostridioides difficile, or C. diff, the culprit of almost half a million infections in the U.S. each year. Surprising findings from a new study in Nature Medicine suggest that the burden of C. diff infection may be less a matter of hospital transmission and more a result of characteristics associated ...

New research provides insight about the bedrock scientific principle that mitochondrial DNA — the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body — is exclusively passed down by the mother. The study, a collaboration among Oregon Health & Science University and other institutions, published today in the journal Nature Genetics. Scientists have long recognized the fact that mitochondrial DNA, or mtDNA, comes exclusively from egg cells in humans, meaning only the mother contributes the genetic code carried by ...

HOUSTON ― Researchers at The University of Texas MD Anderson Cancer Center have discovered that certain nano-based cancer therapies may be less effective in younger patients, highlighting the need for further investigation into the impact of aging on the body’s ability to respond to treatment. The researchers found age-related differences are due to how effectively the liver filters the bloodstream. Younger livers are more efficient at this process, which helps limit toxins in the blood but also filters out beneficial treatments, potentially rendering them ineffective. The study, published today in ...

As we seek more efficient utilization of waste thermal energy, use of “phase change materials (PCMs)” is a good option. PCMs have a large latent heat capacity and the ability to store-and-release heat as they change from one state of matter to another. Among many PCMs, sugar alcohols (SAs), a class of organic compounds commonly used as sweeteners, stand out due to their low cost, non-toxic, non-corrosive, and biodegradable nature. In particular, SAs generally have their melting point in 100–200 °C, which is an important temperature range where a huge amount of waste heat exists but is currently ...

Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations. Agriculture is often blamed for accelerating this process, which is known as zoonotic spillover, through deforestation and habitat fragmentation that reduce biodiversity and increase the likelihood of contact between infected wildlife and humans. But in a Perspectives article published online Sept. 15 in the journal One Earth, University of Michigan ecologist Ivette Perfecto and her colleagues argue that agriculture can both help and hinder: ...

More than 720,000 Floridians will be living with Alzheimer’s disease by 2025. Currently, Florida has the second highest prevalence of Alzheimer’s disease in the United States and is the sixth leading cause of death in Floridians 65 and older. Although the epidemic of age-related brain dysfunction – of which Alzheimer’s disease is a major factor –  is growing at an alarming rate, there is a disconnect between the existing care model designed for urgent care and the progressive nature of this chronic condition, which tends to worsen over time. To address this widespread health concern, Florida Atlantic University’s Schmidt College ...
