Helping to Understand Why Obesity Increases Risk of Cardiovascular Complications in COVID-19
Publicado em 16 novembro 2021
(HealthNewsDigest.com) - In COVID-19 patients, obesity is the factor most associated with the development of endothelial dysfunction, a condition in which the blood vessels become unable to contract and relax adequately, increasing the risk of events such as heart attacks, thrombosis (blood clotting), and stroke.
Endothelium refers to the thin sheet of cells lining the walls of arteries and veins, as well as the inside of the heart. Endothelial cells release substances that control vascular [...]

Investigate How Infection by SARS-CoV-2 Can Lead to Kidney Disorders
Publicado em 30 setembro 2021(HealthNewsDigest.com) - A review article published in the journal Frontiers in Physiology by researchers affiliated with the Federal University of São Paulo (UNIFESP) in Brazil discusses the mechanisms whereby SARS-CoV-2 damages the kidneys, potentially serving as a basis for further research in pursuit of treatments to prevent severe renal problems and even chronic kidney disease in COVID-19 patients. The study shows that interaction with angiotensin-converting enzyme 2 (ACE2) not [...]ver notícia -
Diagnostic Test Delivers Results Within 4 Minutes for Rapid COVID-19 With 90 Percent Accuracy
Publicado em 12 maio 2021HealthNewsDigest.com) - PHILADELPHIA—A low-cost, rapid diagnostic test for COVID-19 developed by Penn Medicine provides COVID-19 results within four minutes with 90 percent accuracy. A paper published this week in Matter details the fast and inexpensive diagnostic test, called RAPID 1.0 (Real-time Accurate Portable Impedimetric Detection prototype 1.0). Compared to existing methods for COVID-19 detection, RAPID is inexpensive and highly scalable, allowing the production of [...]ver notícia -
Controlling Cholesterol in Microglia Alleviates Chronic Pain, Opioid-Free
Publicado em 11 maio 2021(HealthNewsDigest.com) - Chemotherapy can induce a painful peripheral neuropathy (CIPN), a chronic condition and common adverse effect for cancer patients undergoing treatment. Researchers at University of California San Diego School of Medicine, with colleagues elsewhere, have used a mouse model to demonstrate the pivotal role of cholesterol in CIPN, and proposed a novel therapeutic approach to reverse it. The findings are published in the May 10, 2021, online issue of the Journal of [...]ver notícia -
Scientists Seek Faster Route to Treat Depression
Publicado em 05 janeiro 2021Treatment of depression faces two main challenges. The first is that almost 50% of patients do not respond well to existing antidepressants. The second is that conventional medications take a relatively long time – around three to five weeks – to have the desired effect. A group of researchers affiliated with the University of São Paulo (USP) in Brazil set out to tackle the second problem by using epigenetic modulators to try to “erase” the consequences of stress.

Lab-Grown Human Brain Organoids Mimic an Autism Spectrum Disorder, Help Test Treatments
Publicado em 08 dezembro 2020(HealthNewsDigest.com) - Most autism spectrum disorders have a complex, multifactorial genetic component, making it difficult to find specific treatments. Rett syndrome is an exception. Babies born with this form of the disorder have mutations specifically in the MECP2 gene, causing a severe impairment in brain development that primarily affects females. Yet there is still no treatment — current therapies are aimed at alleviating symptoms, but don’t address the root [...]ver notícia -
Scientists Trace the Molecular Roots of Potentially Fatal Heart Condition
Publicado em 27 janeiro 2020(HealthNewsDigest.com) - The heart’s ability to beat normally over a lifetime is predicated on the synchronized work of proteins embedded in the cells of the heart muscle. Like a fleet of molecular motors that get turned on and off, these proteins cause the heart cells to contract, then force them to relax, beat after life-sustaining beat. Now a study led by researchers at Harvard Medical School, Brigham and Women’s Hospital and the University of Oxford shows that when too many of [...]ver notícia -
Needleless Vaccine will Protect Children from Dangerous Viruses
Publicado em 06 maio 2019Millions of people are infected with hepatitis B every year. Hundreds of thousands die. And small children are particularly at risk. Due to high cost and the stable environmental conditions required for vaccine storage, many people in developing countries are not vaccinated against this dangerous virus. As such, researchers have been working to produce a drop or powdered form of oral vaccine. Oral vaccinations are cheaper and more easily administered than injections. However, developing a [...]ver notícia -
Chance of Depression in New Doctors Depends on Where They Train
Publicado em 14 janeiro 2019Nearly 20,000 future doctors will graduate from U.S. medical school this spring, and embark on the residency training that launches their careers. Right now, they’re choosing which hospitals and health systems they’d most like to train at. But a new study suggests that their mental health in the crucial first year of training – called internship – may depend a lot on the nature of the program they enter. Writing in the journal Academic Medicine , a team from the University of Michigan [...]ver notícia -
Large Restaurant Portions a Global Problem, Study Finds
Publicado em 13 dezembro 2018A new multi-country study finds that large, high-calorie portion sizes in fast food and full service restaurants is not a problem unique to the United States. An international team of researchers found that 94 percent of full service meals and 72 percent of fast food meals studied in five countries contained 600 calories or more. The study also found that meals from fast food restaurants contained 33 percent fewer calories than meals from full service restaurants, suggesting fast food [...]ver notícia
