If relaxed too soon, physical distancing measures might have been all for naught

If relaxed too soon, physical distancing measures might have been all for naught - کاهش زودهنگام محدودیت های فاصله گذاری اجتماعی، نتیجه، اصلا فاصله گذاری اجتماعی انجام نشده

If physical distancing measures in the United States are relaxed while there is still no COVID-19 vaccine or treatment and while personal protective equipment remains in short supply, the number of resulting infections could be about the same as if distancing had never been implemented to begin with, according to a UCLA-led team of mathematicians and scientists.

The researchers compared the results of three related mathematical models of disease transmission that they used to analyze data emerging from local and national governments, including one that measures the dynamic reproduction number — the average number of susceptible people infected by one previously infected person. The models all highlight the dangers of relaxing public health measures too soon.

“Distancing efforts that appear to have succeeded in the short term may have little impact on the total number of infections expected over the course of the pandemic,” said lead author Andrea Bertozzi, a distinguished professor of mathematics who holds UCLA’s Betsy Wood Knapp Chair for Innovation and Creativity. “Our mathematical models demonstrate that relaxing these measures in the absence of pharmaceutical interventions may allow the pandemic to reemerge. It’s about reducing contact with other people, and this can be done with PPE as well as distancing.”

Young Adults May Face Severe COVID-19

Young Adults May Face Severe COVID-19 - جوانان هم به موارد شدید کرونا مبتلا می شوند

Smoking Habits Trump Asthma, Obesity in Risk Factors for Otherwise Healthy Population.

As the number of young adults infected with the coronavirus surges throughout the nation, a new study by researchers at UC San Francisco Benioff Children’s Hospitals indicates that youth may not shield people from serious disease.

The study looked at data drawn from a nationally representative sample of approximately 8,400 men and women ages 18 to 25 and concluded that overall “medical vulnerability” was 33 percent for males and 30 percent for females. The impact of smoking surpassed other less common risks, the UCSF researchers reported in their study, which publishes in the Journal of Adolescent Health.

Broken Heart Syndrome During COVID-19 Pandemic

Broken Heart Syndrome During COVID-19 Pandemic - موارد سندرم قلب شکسته در جریان همه گیری کرونا افزایش یافته است

Broken heart syndrome, or stress cardiomyopathy, occurs in response to stressful events.

Cleveland Clinic researchers have found a significant increase in patients experiencing stress cardiomyopathy, also known as broken heart syndrome, during the COVID-19 pandemic.

Stress cardiomyopathy occurs in response to physical or emotional distress and causes dysfunction or failure in the heart muscle. Patients typically experience symptoms similar to a heart attack, such as chest pain and shortness of breath, but usually do not have acutely blocked coronary arteries. The left ventricle of the heart, however, may show enlargement. Other symptoms include irregular heartbeat, fainting, low blood pressure and cardiogenic shock (an inability of the heart to pump enough blood to meet the body’s demands due to the impact of stress hormones on the cells of the heart).

The study was published today in JAMA Network Open.

Kids Rarely Transmit Covid-19

Kids Rarely Transmit Covid-19 - کودکان به ندرت کرونا را به دیگران منتقل می کنند

Kids Rarely Transmit Covid-19, Say UVM Docs in Top Journal
Schools Can Reopen in Fall, They Say, If Safety Guidelines Are Observed and Community Transmission Is Low.

A commentary published in the journal Pediatrics, the official peer-reviewed journal of the American Academy of Pediatrics, concludes that children infrequently transmit Covid-19 to each other or to adults and that many schools, provided they follow appropriate social distancing guidelines and take into account rates of transmission in their community, can and should reopen in the fall.

Researchers Create Air Filter Designed to Trap and Kill the Coronavirus

Researchers Create Air Filter Designed to Trap and Kill the Coronavirus - محققان نوعی فیلتر هوا ساخته اند که می تواند کرونا ویروس را از بین ببرد

Researchers from the University of Houston, in collaboration with others, have designed a “catch and kill” air filter that can trap the virus responsible for COVID-19, killing it instantly.

Zhifeng Ren, director of the Texas Center for Superconductivity at UH, collaborated with Monzer Hourani, CEO of Medistar, a Houston-based medical real estate development firm, and other researchers to design the filter, which is described in a paper published in Materials Today Physics.

The researchers reported that virus tests at the Galveston National Laboratory found 99.8% of the novel SARS-CoV-2, the virus that causes COVID-19, was killed in a single pass through a filter made from commercially available nickel foam heated to 200 degrees Centigrade, or about 392 degrees Fahrenheit. It also killed 99.9% of the anthrax spores in testing at the national lab, which is run by the University of Texas Medical Branch.
