Study describes associations between gender-affirming hormone therapy and body weight changes

Gender-affirming hormone therapy is the bedrock of medical therapy for many transgender and gender diverse individuals. Some adult transgender individuals decide with their health care provider to start hormone therapy – testosterone for transmasculine people and generally a combination of estrogen and antiandrogens for transfeminine people – specifically for the physical and psychological effects these hormones produce, including changes to the voice, skin, facial and body hair and body composition. However, in the context of the global obesity epidemic, little is known about obesity rates and weight changes in adults treated with gender-affirming hormone therapy.

Researchers develop novel sealant patch for preventing intestinal leakage

A burst appendix or a life-threatening intestinal volvulus are emergencies that need to be treated by surgeons immediately. However, a life-saving operation, in which tissue from the digestive tract has to be reattached, bears some risks. After all, everything that is transported through the gastrointestinal tract to the outside world in fact belongs there - and should under no circumstances end up inside the abdominal cavity.

People cannot perceive decrease in body temperature when exercising, study finds

In a study published this month in Physiology & Behavior, research teams at the University of Tsukuba, led by Takeshi Nishiyasu, and at Niigata University of Health and Welfare, led by Tomomi Fujimoto, have found that, when exercising, people cannot perceive decreases in their core body temperature caused by the cold as well as they can when they are resting. This research has implications for recreational activities in colder climates, such as hiking and skiing.

Novel system may enable noninvasive and more precise measurement of cerebral blood flow

In order to function properly, the brain requires a steady flow of blood through the cerebral arteries and veins, which deliver oxygen and nutrients and also remove metabolic byproducts. Therefore, cerebral blood flow is considered a vital and sensitive marker of cerebrovascular function. Optical methods offer a noninvasive approach for measuring cerebral blood flow.
