New IR treatment for 'tennis elbow' reduces pain and inflammation without surgery
Tennis elbow, the painful chronic condition that affects up to 3 percent of the US adult population, can be effectively treated through transcatheter arterial embolization (TAE), an image-guided, non-surgical treatment that decreases abnormal blood flow to the injured area to reduce inflammation and pain, according to research presented today at the Society of Interventional Radiology's 2019 Annual Scientific Meeting.

Investigational obesity drug, oxytocin, weakens brain's reward signals for food
The hormone oxytocin reduces the communication between different brain areas involved in the cognitive, sensory and emotional processing of food cues that people with obesity demonstrate when they look at high-calorie foods, according to research being presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

BPA exposure during pregnancy can alter circadian rhythms
Exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated 'safe' human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.
Autoimmune diseases are related to each other, some more than others
Researchers using the world's largest twin registry to study seven autoimmune diseases found the risk of developing the seven diseases is largely inherited, but that some diseases are more closely related than others.

Despite an FDA approval of growth hormone treatment for children with idiopathic short stature (ISS), the mean cost burden to patients and their families has increased over time.
Genetic rickets improves more with burosumab than standard care, study finds

Study highlights detrimental effect of overlooking female athletes' nutritional needs
As poor nutrition can negatively affect everything from bone to reproductive health, more attention needs to be paid to the specific nutritional needs of female athletes, a collaborative study from New Zealand's University of Otago and University of Waikato argues.
Chemicals in household dust may promote fat cell development
Endocrine-disrupting chemicals present in household dust promote the development of fat cells in a cell model and could contribute to increased growth in children relative to their age, according to research to be presented Monday, March 25, at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

Insomnia Line
Coronasomnia is a not-so-surprising side-effect of the global pandemic. More and more of us are having trouble falling asleep. We wanted to find a way to get inside that nighttime world, to see why people are awake and what they are thinking about. So what'd Radiolab decide to do?  Open up the phone lines and talk to you. We created an insomnia hotline and on this week's experimental episode, we stayed up all night, taking hundreds of calls, spilling secrets, and at long last, watching the sunrise peek through.   This episode was produced by Lulu Miller with Rachael Cusick, Tracie Hunte, Tobin Low, Sarah Qari, Molly Webster, Pat Walters, Shima Oliaee, and Jonny Moens.
