COLCHESTER, VT – Researchers from Saint Michael’s College and the University of Vermont have made a groundbreaking new discovery that provides a better understanding of how Alzheimer’s disease develops in the human brain.  Guided by previous research of spider brains, the scientists uncovered evidence of a “waste canal system” in the human brain that internalizes waste from healthy neurons. They discovered that this system can undergo catastrophic swelling, which leads to the degeneration of brain tissue, a hallmark of Alzheimer’s disease.  With over 50 million affected people worldwide, Alzheimer’s ...

Key study findings: The rate of pharmacy store closures in recent years has more than doubled, affecting about 1 in 3 pharmacies between 2010 and 2021 and contributing to an unprecedented decline in the availability of pharmacies in the U.S   About one-third of counties experienced an overall decline in pharmacies, and the risk of closure was higher in predominantly Black and Latino neighborhoods. Independent pharmacies, often excluded from networks by pharmacy benefit managers, were more than twice as likely to face closure compared to chain pharmacies.   Policymakers should consider several ...

It might seem out of place on the side of a highway, but purpose-built exercise equipment installed at truck stops across Australia could be just the thing to encourage truck drivers to take a break and take control of their health and wellbeing.   In the first meta-analysis of how health behaviour interventions can affect truck drivers, researchers at the University of South Australia have found that tailored, multi-level and innovative approaches to truck driver health are required to enact positive change, as current interventions are not working.   Reviewing the effectiveness of health interventions for more than 2000 truck drivers across 19 studies, researchers found ...

Treatment for more advanced and difficult-to-treat head and neck cancers can be improved with the addition of polyvinyl alcohol (PVA), the same ingredient used in children’s glue. Researchers found that combining PVA with a boron-containing compound, D-BPA, improved the effects of a type of radiation therapy for cancer, compared to currently clinically used drugs. The PVA made the drug more selective of tumor cells and prolonged drug retention, helping to spare healthy cells from unnecessary radiation damage.  Japan became the first country to approve boron neutron capture therapy (BNCT), a type of targeted radiotherapy for cancer, in 2020. Doctors ...

Democracy is in crisis. Many people are losing confidence in political parties and parliaments and their ability to solve pressing social problems in the long term. Recent studies by the University of Stuttgart indicate that addressing doubts about the democratic system does not necessarily require resorting to the election of an autocratic head of state. Rather, more direct political participation could revitalize and legitimize democracy - provided that innovative participatory formats are intelligently linked to the work of representative institutions. “Many people consider representative politics to be tiring ...

Toronto, ON – Transgender and gender-diverse preteens are about 15% less physically active than their cisgender peers, new research finds. Transgender 11-12 year-olds take, on average, 1,394 fewer steps per day compared to cisgender adolescents, a difference that equates to about 12% of the daily physical activity recommended for adolescents. The study was published in Annals of Epidemiology. “Transgender adolescents may experience stigma and discrimination that discourage their participation in team sports or physical activity,” ...

In late 2022, OpenAI released ChatGPT, an artificial intelligence (AI) chatbot able to generate conversational answers and analyses, as well as images, in response to user questions and prompts. This generative AI was built with computational procedures, such as large language models, that train on vast bodies of human-created and curated data, including scientific literature. Since then, the worry that AI may someday outsmart humans has grown more widespread. In a new collection of essays, leading ...

About The Study: In this cohort study of 1,600 emergency medicine patient medical records, large language model (LLM)-generated emergency medicine-to-inpatient handoff notes were determined superior compared with physician-written summaries via conventional automated evaluation methods, but marginally inferior in usefulness and safety via a novel evaluation framework. This study suggests the importance of a physician-in-loop implementation design for this model and demonstrates an effective strategy to measure pre-implementation patient safety of LLM models.  Corresponding ...

Patients with frontotemporal dementia often lack the ability to empathize. A study at Karolinska Institutet has now shown that these patients do not show the same brain activity as healthy individuals when they witness the pain of others, a finding that it is hoped will increase understanding of this specific dementia disease. Around 25 000 Swedes are affected by dementia every year. Of these, about three percent are diagnosed with frontotemporal dementia. The disease is difficult to diagnose, but one of its characteristics is that sufferers lose the ability to empathize, which can lead to problems for them, and not least ...

CAMBRIDGE, MA -- Gastric balloons — silicone balloons filled with air or saline and placed in the stomach — can help people lose weight by making them feel too full to overeat. However, this effect eventually can wear off as the stomach becomes used to the sensation of fullness. To overcome that limitation, MIT engineers have designed a new type of gastric balloon that can be inflated and deflated as needed. In an animal study, they showed that inflating the balloon before a meal caused the animals to reduce their food intake by 60 percent. This type of intervention ...

Voice experiments in people with epilepsy have helped trace the circuit of electrical signals in the brain that allow its hearing center to sort out background sounds from their own voices. Such auditory corollary discharge signals start and end in two subregions of the brain’s top folded surface, or cortex, a new study shows. One large part of the cortex, the motor cortex, is known to control the body’s voluntary muscle movements, including those involved in speech, while another large section, the auditory cortex, is known to control hearing. In terms of evolution, the ability of animals and humans to tell ...
