The COVID-19 pandemic has enabled researchers to show that a long course of radiotherapy given before surgery may be a better treatment for avoiding surgery, preserving the rectum and anus, and preventing regrowth of the primary tumour than a short course of radiotherapy for patients with rectal cancer – a type of bowel cancer. However, the overall survival and survival free of recurrence of the disease remained the same for both treatments.   These findings are from a new study published in ...

As more people with type 2 diabetes (T2D) are taking medications to help manage blood sugar levels and weight loss, concerns about whether these drugs are safe have emerged. Now real-world evidence from the FDA Adverse Event Reporting System (FAERS) database reveals a reassuring safety profile for tirzepatide (TZP). The findings to be presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Madrid (9-13 Sept), and published in the The Journal of Endocrinological Investigation (link below) reveal that, compared to the widely used class of glucagon-like peptide-1 receptor agonists (GLP-1 RAs), TZP has similar gastrointestinal ...

All doses of tirzepatide, a medication approved in the EU to treat type 2 diabetes and obesity, consistently reduced body weight in women and men, but women experienced greater weight loss, according to new post hoc research to be presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Madrid (9-13 Sept). The post hoc analysis, which included the four SURMOUNT trials [1], compared tirzepatide with a placebo for up to 72 to 88 weeks in 4,677 adults (2,999 females, 1,678 males) living with obesity, highlighting potential sex differences in the response. Tirzepatide, a once-weekly glucose-dependent ...

Swiftly achieving glycaemic control after a diagnosis of gestational diabetes can bring the baby’s risk obesity in childhood down to a level similar to that of children whose mothers did not have gestational diabetes, new research being presented at the annual meeting of the European Association for the Study of Diabetes (EASD) in Madrid, Spain (9-13 September), has found. Gestational diabetes, a type of diabetes that can develop during pregnancy, affects 14% of pregnant women globally and is becoming more common, with those who are living with obesity, have a family ...

The anti-obesity medication semaglutide may help to prevent heart attacks, strokes, and other major adverse cardiovascular events (MACE) as well as death in adults with overweight or obesity who don’t have diabetes, whether or not they also have impaired kidney function, according to new research to be presented at this year’s Annual Meeting of The European Association for the Study of Diabetes (EASD), Madrid (9-13 Sept). The results are based on a pre-specified analysis of the SELECT trial which found that adults with overweight or obesity but not diabetes taking semaglutide for more than 3 years had a 20% lower risk of MACE or ...

The phase 3 SURPASS-4 trial published in 2021 established that tirzepatide lowers blood sugar and supports weight loss better than insulin glargine (a long-acting insulin) for type 2 diabetes (T2D) [1]. Now new research examining a broad range of potential predictors of sustaining blood sugar control and weight loss indicates that greater weight loss, better β-cell function, and a greater decrease in low-density lipoprotein cholesterol (LDL-C or “bad cholesterol”) during the first year of tirzepatide therapy are the most ...

Avian influenza A(H5N1) virus, which spread to cattle and infected 14 people this year, was detected using virome sequencing in the wastewater of 10 Texas cities by researchers at UTHealth Houston and Baylor College of Medicine. The virome is the collection of viruses in a sample, in this case a wastewater sample. The information was published in the New England Journal of Medicine. Until March 2024, H5N1 had not been detected in 1,337 wastewater samples analyzed by the team. But from March 4 to July 15 (the end of data collection for this article), H5N1 was ...

Harvard stem cell biologists have pioneered a groundbreaking 3D organoid culture method for generating large numbers of adult skeletal muscle satellite cells, also known as muscle stem cells, in vitro.

New findings from McGill University researchers could help clinicians understand the course of delusions in youth and young adults that signal the need for a timely intervention to prevent a full relapse of psychosis. Delusions — strong beliefs that don't align with commonly accepted reality— are a defining symptom of psychosis but are not sufficiently understood. For the first time, researchers studied whether delusion themes, such as paranoia or grandiosity, stay the same or shift between psychotic episodes in youth and young adults undergoing early intervention treatment. The importance of timely ...

As the world tries to mitigate agriculture’s effect on the environment, much of the story can be found in the soils, which stores and cycles nutrient elements of carbon, nitrogen, and phosphorus. Biogeochemistssuch as Andrew Margenot, Associate Director of the Agroecosystem Sustainability Center, are set to find answers, but for Margenot and other biogeochemistry experts who specialize in studying phosphorus cycling, the challenge is first being able to accurately measure where phosphorus has accumulated in the <100 years since humans began to increase ...

A team of doctors and researchers at Memorial Sloan Kettering Cancer Center (MSK) have identified a new, rare type of small cell lung cancer that primarily affects younger people who have never smoked. Their findings, which include a detailed analysis of the clinical and genetic features of the disease, also highlight vulnerabilities that could help doctors make better treatment decisions for people diagnosed with it. “It’s not every day you identify a new subtype of cancer,” says Natasha Rekhtman, MD, PhD, an MSK pathologist specializing in lung cancer and the first author of a paper published August 26 in Cancer Discovery presenting ...

Outdoor light at night could be a significant risk factor in Alzheimer’s disease, according to new research from Rush. While light pollution is associated with increased risk of some disorders and diseases, this is the first time it had been associated with Alzheimer’s disease. The study was conducted at Rush University System for Health and published in Frontiers in Neuroscience. “Our research shows that there is an association in the U.S. between Alzheimer’s disease prevalence and exposure to light at night, particularly in those under the age of 65,” said lead investigator, Robin Voigt-Zuwala, PhD, an associate professor at Rush. “Nightly ...

      Graphics  //  Photos The earliest humans to settle the Great Lakes region likely returned to a campsite in southwest Michigan for several years in a row, according to a University of Michigan study.   Until recently, there was no evidence that people from the Clovis period had settled the Great Lakes region. Clovis people appeared in North America about 13,000 years ago, during the geologic epoch called the Pleistocene. During the Pleistocene, sheets of glaciers covered much of the world, including Michigan, making the land inhospitable for human settlers. But a 2021 U-M study confirmed that Clovis people built ...

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET, WEDNESDAY, SEPTEMBER 11, 2024 MINNEAPOLIS – People who have had a stroke may be more likely to sleep too much or too little compared to those without prior stroke, according to a study published in the September 11, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
