Just five minutes of vigorous exercise a day might help lower blood pressure, a new study suggests. People with high blood pressure have a higher risk for heart disease and stroke, the leading causes of death in the U.S. Nearly half of all Americans have high blood pressure, which is defined as a systolic blood pressure (the upper number) of greater than 130 or a diastolic blood pressure (the lower number) greater than 80. The researchers found that replacing any less active behavior with five minutes of exercise could lower systolic blood pressure by 0.68 points and diastolic blood pressure by 0.54 points. An estimated two point improvement in systolic blood pressure was observed when 20 minutes of vigorous exercise replaced, for example, 21 minutes of sedentary time or 26 minutes of slow-walking.

Nearly 1 in 3 Americans may have an undiagnosed iron deficiency, a problem that can lead to fatigue, brain fog and difficulty concentrating, a new study suggests. An analysis of data from more than 8,000 adults in the U.S. revealed that 14% had low iron blood levels, a condition known as absolute iron deficiency, while 15% had the right iron levels but their bodies couldn’t use the essential mineral properly, known as functional iron deficiency, according to the report published Tuesday in JAMA Network Open. Doctors don’t typically screen adults for iron deficiency, which is why the condition has been overlooked in many people. There had been hints in other studies suggesting iron deficiency might be more widespread than doctors assume. The rates of iron deficiency between men and women are more similar after the age of menopause, experts said.

For many people, reaching their mid-40s may bring unpleasant signs the body isn’t working as well as it once did. Previous research showed that resting energy use, or metabolic rate, didn’t change from ages 20 to 60. The changes in metabolism affect how the body reacts to alcohol or caffeine, although the health consequences aren’t yet clear. For example, the changes in alcohol metabolism might be because people are drinking more in their mid-40s, Snyder said. “But it will take time to sort out what individual changes mean and how we can tailor medications to those changes.

“Now, post-surgery and post recovery, I am able to see in dimmer lighting with my left eye,” Cook said. A treatment that used CRISPR was found to be safe and efficacious in improving vision among a small sample of patients with inherited blindness in the Phase 1/2 clinical trial that Cook participated in. Months following the treatment, Cook was sitting with friends on a balcony that had Christmas lights wrapped around the railing. Courtesy Olivia CookBefore the treatment, Cook said that she sometimes could conceal the vision challenges she has had. Mass Eye and EarKalberer described the CRISPR treatment as “groundbreaking,” but warned it’s not a cure.

☆ WHO clarifies what counts as a pathogen that can spread through the air

“Airborne transmission” refers to when infectious respiratory particles expel into the air, such as from coughing or sneezing, and enter the respiratory tract of another person who inhales them, according to WHO. The subcategory “direct deposition” refers to when infectious respiratory particles expel into the air and directly land on another person’s mouth, nose or eyes, potentially causing infection. “Public health agencies were hesitant to use the word ‘airborne’ because of differences in understanding among experts about what it meant. When I say ‘aerosol’, when I say ‘through the air’, it doesn’t matter whether I’m an engineer, a clinician, a nurse, a public health person. ‘There were many failures’During the pandemic, various terms were used in different ways to describe how the coronavirus could spread, causing much confusion – terms like airborne, airborne transmission or aerosol transmission.

Gender-affirming care has become a key political issue for conservatives in the run-up to the presidential election. According to the analysis, about 48,000 patients underwent surgeries from 2016 through 2020. Breast and chest surgeries were the most common: There were about 27,187, or 56.6 percent of all gender-affirming surgeries. Background: Recent developments in gender-affirming care. Earlier this month, the American Academy of Pediatrics reaffirmed its guidelines regarding the gender-affirming treatment but also commissioned a fresh review of the research, after European health authorities found uncertain evidence for its effectiveness.

☆ If you're sitting all day, science shows how to undo the health risks. Take 'activity snacks' every 30 minutes.

“If we don’t use them, things don’t work right.”When it comes to blood pressure, moving around helps improve circulation, Diaz said. Blood pressure and blood sugar were measured during each phase of the study. The strategy that worked best was five minutes of walking for every 30 minutes of sitting. All walking strategies resulted in a significant reduction of 4 to 5 blood pressure points, compared to sitting all eight hours. "When you do it without breaks, your blood pressure goes up and there are elevations in blood sugar.”Do standing desks help?

Chickenpox vaccines have virtually wiped out severe complications and deaths in American children from the highly contagious virus, a new report finds. Chickenpox —which is caused by the varicella-zoster virus, a type of herpes virus — was considered just a normal part of growing up until the vaccine became available in 1995. The chickenpox vaccine implementation is “a tremendous achievement,” said the study’s lead author, Dr. Mona Marin, a medical epidemiologist at the CDC’s National Center for Immunization and Respiratory Disease. An estimated 90.3% of children have been vaccinated against chickenpox by age 2, according to the CDC. The CDC recommends two doses of chickenpox vaccine for children, teens and adults who have never had the disease.
