Face masks have negligible negative effect on CO2 and O2 levels

A new study suggests that face masks have a negligible negative effect on the levels of carbon dioxide and oxygen that a person breathes.

The findings even hold true for individuals with chronic obstructive pulmonary disease (COPD).

The research, which appears in the journal Annals of the American Thoracic Society, contributes to dispelling some of the myths surrounding the use of face masks in the context of the ongoing COVID-19 pandemic.

As the world gains access to more information about SARS-CoV-2, the virus that causes COVID-19, scientists have become increasingly convinced that masks can help reduce its spread.

The primary way that SARS-CoV-2 transmits involves viral particles entering a person’s respiratory tract. This typically happens after another person coughs, sneezes, or speaks near them, producing droplets or aerosols that transport the virus.

Consequently, face masks play an important role in reducing exposure to the virus and limiting the amount

Solid Biosciences’ (SLDB) Stock Will Surge Over 200% From Current Levels, Says Analyst

11 months ago, the U.S. Food and Drug Administration (FDA) shut down Solid Biosciences’ (SLDB) “IGNITE DMD” Phase I/II clinical trial after one of the young patients involved in the trial suffered a “serious adverse event.” Despite the patient in question recovering, no new patients suffering such serious adverse events, and the company providing the FDA with “information and measures intended to improve patient safety” and “data related to manufacturing process improvements,” the FDA declined to allow trials to resume in July, and asked Solid Biosciences to provide even more information on its trials, and on the safety measures it proposed to add to get the trials back on track.

Fast forward three more months and — success!

On Thursday, Solid Biosciences confirmed that the FDA has “lifted the clinical hold” on its trials, acknowledging that the company has “satisfactorily addressed all clinical hold questions.” Going forward, the

England Women must improve to reach USA fitness levels, Dawn Scott tells The Women’s Football Show | Football News

England Women’s physical performance manager Dawn Scott has warned them they must improve their fitness drastically if they are to reach the same level as their USA counterparts.

South Shields-born Scott was employed by the FA and used to work under Hope Powell when she was in charge of the England Women’s team.

Scott subsequently made the switch to join the USA Women’s backroom staff in 2010 but, after playing her part in helping them to claim consecutive World Cups in 2015 and 2019, she returned to her native country’s national team set-up last year.

She is now tasked with preparing England for the 2021 European Championships on home soil but – in an exclusive interview with The Women’s Football Show – she gave some indication of how hard England will have to work if they are to improve.

“The fitness results from the US team are just engrained in

Elderly hit so hard by COVID-19 because of lower levels of certain immune cells

Elderly people who get COVID-19 have lower levels of important immune cells, which may explain why they are more likely than younger patients to have severe symptoms or die, new research suggests.

For the study, the researchers analyzed blood samples from 30 people with mild COVID-19, ranging in age from the mid-20s to late-90s. Compared with healthy people, all of the COVID-19 patients had lower numbers of T cells — which target virus-infected cells — in their blood.

But COVID-19 patients over 80 years of age had fewer T cells than those who were younger, and so-called “killer” T cells in older patients produced lower amounts of cytotoxic molecules that find and kill infected cells, the investigators found.

This age-related difference in immune response may partially explain why older COVID-19 patients have more severe illness, according to the authors of the study published this month in the journal mBio.
