When the Covid public health emergency expired in May, health officials in Oregon decided it was also time to pull back on the recommendation that its residents, including schoolchildren, isolate for five days after testing positive for the virus.
Instead, the Oregon Health Authority suggested that people with Covid stay home only until they’ve gone without spiking a fever for 24 hours and are generally feeling better.
The move was a break from guidance from the Centers for Disease Control and Prevention, which continues to recommend that people stay home for a five-day period and stay away from household members.Read More…

If you find a bottle of sunscreen packed in last year’s pool bag, here’s a suggestion: Toss it out. Since the active compounds can degrade and lose their effectiveness, slathering on old lotion or spray is one mistake people make when trying to protect their skin.
Each year about 84,000 people in the U.S. are diagnosed with melanoma and more than 8,000 die from this type of skin cancer. In addition, millions of cases of basal cell and squamous cell carcinomas are diagnosed each year, and about 90% of these skin cancers are linked to ultraviolet (UV) radiation from the sun.Read More…

The risk of a blood clot breaking off and traveling around the body is highest within the first 4 weeks after it initially forms. However, healthcare professionals are unsure of exactly how long it takes for a blood clot to travel around the body. The above timeframe comes from an older 2014 article from the American Heart Association’s journal, Circulation.
A blood clot happens when various substances form a solid mass inside the blood vessels. These clots can form in one part of the body before breaking off from an artery or vein. The circulatory system can then carry this blood clot to blood vessels in different parts of the body.
In some cases, this can cause serious health problems. For instance, blood clots that originate in veins can travel to the lungs, leading to pulmonary embolism (PE). Blood clots that originate in the arteries can travel to the brain, causing a stroke.Read More…
Children need quiet environments to help early brain development

A group of small children sits cross-legged with their teacher, Steve Mejía-Menendez, on a round carpet. He’s a pre-K teacher at Lee Montessori Public Charter School’s campus in Southeast Washington, D.C., and although I’m here to meet him, I almost don’t spot him because he’s eye level with his students.
Mr. Steve, as he’s known here, is talking a few students through a geometry lesson when another student approaches to ask an unrelated question. This kind of distraction happens all the time in classrooms around the United States. Mr. Steve doesn’t lose focus. He uses American Sign Language to say “wait” — palms facing up, fingers wiggling — and the child waits quietly. When the lesson arrives at a natural stopping point, the student is invited to ask his question, and Mr. Steve silently responds by nodding his head along with his fist, which is sign language for “yes.”Read More…

The United States Preventive Services Task Force on Tuesday created new draft guidelines recommending all women begin screening mammography at age 40, a decade earlier than previous guidelines, and continue screenings every other year until age 74.
The change is bound to be controversial, adding fresh fuel to a long-standing debate around when people should begin breast cancer screening, how often they should do it, and if specific groups, such as Black women, ought to be screened differently.Read More…

A common genus of microbe found in wet, boggy environments could play a key role in the development of Parkinson’s disease, by excreting compounds that trigger proteins inside brain cells to form toxic clumps.
The findings, made by a small team of researchers at the University of Helsinki and the University of Eastern Finland, build on the results of an earlier investigation showing that the severity of the neurodegenerative disorder in volunteers increased with concentrations of Desulfovibrio bacterial strains in their feces.
By now demonstrating a potential path from the presence of the bacteria in genetically edited worms to physical changes in the brain that coincide with Parkinson’s disease, the researchers hope to one day improve early diagnosis of the disease in humans, or even slow its progress.Read More…
