Using an innovative method for measuring doctor turnover, Weill Cornell Medicine researchers determined that between 2010 and 2018, the annual rate at which physicians left their practices increased by 43 percent, from 5.3 percent to 7.6 percent a year.  The causes of this trend are not known, but warrant further investigation, according to the researchers. The study, published July 11 in the Annals of Internal Medicine, also found that the first three quarters of 2020 (the start of the COVID-19 pandemic in the United States) were not associated with higher turnover. However, more data are needed to fully understand turnover trends related to COVID-19. Whether doctors ...

“This evidence strengthens the relevance of the findings by Pietrobono et al., shedding light on the potential application of SMO inhibitors in concert with BRD4 inhibitors.” BUFFALO, NY- July 19, 2023 – A new editorial paper was published in Oncotarget's Volume 14 on May 26, 2023, entitled, “Combined targeting of HEDGEHOG signaling and BRD4 as a novel therapeutic option against melanoma.” The Hedgehog-GLI (HH/GLI) pathway is aberrantly activated in several types of cancer. Canonical HH/ GLI pathway is triggered by binding of HH ligands to the twelve-pass transmembrane receptor Patched 1 (PTCH1), which retrieves its inhibition ...

A study of data from about 500,000 people in the UK Biobank has uncovered small but statistically significant associations between signs of systemic inflammation and later risk of dementia. Dr. Krisztina Mekli of The University of Manchester, UK, and colleagues present these findings in the open-access journal PLOS ONE on July 19, 2023. Millions of people around the world have Alzheimer’s disease or other types of dementia, and researchers are working to tease out the complex mechanisms behind these conditions. Prior research has suggested that inflammation—activation of the body’s innate immune system—may ...

Women working as STEM instructors are more likely than men in the same profession to disclose to their undergraduate students identities which could carry stigma, such as depression or growing up in a low-income household. In the new study, published July 19, 2023 in the open-access journal PLOS ONE, Carly Busch of Arizona State University, USA, and colleagues suggest that these decisions to disclose may be in order to act as role models for students. Concealable stigmatized identities (CSIs) are identities that ...

Philadelphia, July 19, 2023—Why do nonsteroidal anti-inflammatory drugs (NSAIDs) exacerbate gastrointestinal infections by Clostridioides difficile, the leading cause of antibiotic-associated diarrhea worldwide? In a new paperpublished in Science Advances, researchers at Children’s Hospital of Philadelphia (CHOP) have begun to answer that question, showing that NSAIDs disrupt the mitochondria of cells lining the colon, sensitizing them to damage by pathogenic toxins.  Clostridioides ...

A 300,000-year-old hunting weapon has shone a new light on early humans as woodworking masters, according to a new study. State-of-the-art analysis of a double-pointed wooden throwing stick, found in Schöningen in Germany three decades ago, shows it was scraped, seasoned and sanded before being used to kill animals. The research indicates early humans’ woodworking techniques were more developed and sophisticated than previously understood. The findings, published today (Wednesday, 19 July) in PLOS ONE, also suggest the ...

A research group in Carnegie Mellon University's Robotics Institute is creating the next generation of explorers — robots. The Autonomous Exploration Research Team has developed a suite of robotic systems and planners enabling robots to explore more quickly, probe the darkest corners of unknown environments, and create more accurate and detailed maps. The systems allow robots to do all this autonomously, finding their way and creating a map without human intervention. "You can set it in any environment, like a department store or a residential building after a disaster, and off it goes," ...

What determines whether we become overweight? Aside from lifestyle, predisposition plays a role, but genes cannot fully explain the inherited propensity to accumulate excess weight. A new study by Charité – Universitätsmedizin Berlin in Science Translational Medicine* shows that a kind of formatting of the DNA code in one gene that is associated with satiety is implicated in a slightly elevated risk of excess body weight – at least in women. This “epigenetic marking” is established early on during the embryonic stage. People who are overweight, especially those who ...

“Don’t eat me!” That’s how one might translate the signal that the cancer cells in a glioblastoma send to the macrophages (white blood cells specialized in removing dead and dying cellular matter) in the brain. Immunotherapy attempts to enable these cells to eradicate the abnormal cells, but so far, it has met with little success when it comes to glioblastomas. Researchers led by Professor Gregor Hutter from the Department of Biomedicine at the University and University Hospital Basel have recently used patient data, experiments with mice, and samples from human tumors to study one of these “don’t eat me!” signals and its inhibitory ...

The research, funded by the British Heart Foundation and published in the journal Circulation, opens the prospect of treating the condition at the earliest stages. Being able to detect HCM earlier than ever before will also assist trials investigating gene therapies and drug treatments aimed at stopping the disease developing in those at risk. HCM is an inherited condition that affects around 1 in 500 people in the UK. It causes the muscular walls of the heart to become thicker than normal, affecting how well the heart can pump blood around the body. It is ...

A good battery needs two things: high energy density to power devices, and stability, so it can be safely and reliably recharged thousands of times. For the past three decades, lithium-ion batteries have reigned supreme — proving their performance in smartphones, laptops, and electric vehicles. But battery researchers have begun to approach the limits of lithium-ion. As next-generation long-range vehicles and electric aircraft start to arrive on the market, the search for safer, cheaper, and more powerful ...

The longest nerve in the human body starts in the brain and meanders its way down the neck and into the chest, where it splits into separate branches, winding its twisting tendrils to touch each internal organ. Known as the “information superhighway” and aptly named from the Latin word meaning “wanders,” the vagus nerve is a bundle of fibers responsible for the parasympathetic nervous system: digestion, heart rate, breathing.  Sending electrical impulses down this tenth cranial nerve has proven effective in treating conditions like depression and epilepsy, ...

The formation of the country’s first emergency department for the over 80s led to a significant decrease in time spent in A&E – according to research from the Norfolk and Norwich University Hospital (NNUH) and University of East Anglia (UEA). The first Older People’s Emergency Department in England was opened at NNUH in December 2017 to bring specialists in older people’s medicine to the front doors of the hospital and provide earlier assessment and treatment for patients. A new study evaluates the outcomes for patients who received treatment in the main emergency department at NNUH and a similar ...

Have you ever wondered why some people never became sick from COVID-19? A study published today in Nature shows that common genetic variation among people is responsible for mediating SARS-CoV-2 asymptomatic infection. The results indicate that individuals having this variant never feel sick once infected. This exciting discovery was a result of a U.S.-Australia collaborative work led by Danillo Augusto, Ph.D., assistant professor at the University of North Carolina at Charlotte; Jill Hollenbach, Ph.D., professor ...

Nearly a century ago, physicists Max Born and J. Robert Oppenheimer developed an assumption regarding how quantum mechanics plays out in molecules, which are comprised of intricate systems of nuclei and electrons. The Born-Oppenheimer approximation assumes that the motion of nuclei and electrons in a molecule are independent of each other and can be treated separately. This model works the vast majority of the time, but scientists are testing its limits. Recently, a team of scientists demonstrated the breakdown ...

Women with Lyme disease take longer to get diagnosed, have more severe symptoms and experience higher rates of disability when compared to men. They may also be more likely to develop persistent Lyme disease. Those are among the findings of a recent study that analyzed information from the MyLymeData patient registry. The results have been published in the International Journal of General Medicine. The present study, which was conducted by LymeDisease.org, a research and advocacy organization, assessed sex-based differences in Lyme disease patients who remained ill for six months or more after antibiotic treatment. In ...
