New study finds a stark decrease in the number of abdominal surgeries among older adults Many have assumed that the rates of major abdominal surgeries in adults over 65 is increasing over time as the U.S. population ages and as new technology renders surgical procedures safer for older adults. Contrary to this popular belief, a new study from the University of Chicago Medicine found the frequency of abdominal surgery in older adults is decreasing, especially among adults over the age of 85. The study, which examined data from 2002 to 2014, was published May 10 in the Journal of the American ...

AI methods predict COVID-19 patient outcomes using routine clinical data from ICUs The investigators used machine learning to predict which patients might get worse and not respond positively to being turned onto their front in intensive care units (ICUs) - a technique known as proning that is commonly used in this setting to improve oxygenation of the lungs. While the AI model was used on a retrospective cohort of patient data collected during the pandemic's first wave, the study demonstrates the ability of AI methods to predict patient outcomes using routine clinical information used by ICU...

Coronavirus (CoVs) infection in animals and humans is not new. The earliest papers in the scientific literature of coronavirus infection date to 1966. However, prior to SARS-CoV, MERS-CoV, and SARS-CoV-2, very little attention had been paid to coronaviruses.

Study shows possible link between intestinal polyps in close relatives and colorectal cancer risk Cancer of the colon and rectum is one of the deadliest forms of cancer, and has in recent years affected growing numbers of young people. In the largest registry study to date, researchers at Karolinska Institutet in Sweden and Harvard University in the USA demonstrate a possible connection between colorectal polyps in close relatives and the risk of developing colorectal cancer. The study, which is published in the British Medical Journal, is of potential consequence for different countries' sc...

Study reveals mechanisms that cause muscle weakness in patients with Becker disease Muscle weakness in patients with Becker disease is caused by unusual electrical activity in muscle fibres termed 'plateau potentials' that make them temporarily inactive, says a study published today in eLife. An understanding of these mechanisms and the ion channels involved may help the search for more effective therapies for weakness in Becker disease and other muscle diseases, and help understand how electrical activity is regulated in muscles. Recessive myotonia congenita, also known as Becker disease, i...
