Flying, children’s blood vessels, pepper sprays & the office

How Safe Is Flying in the Age of Coronavirus? link

Just like with SARS back in 2003, air travel has helped spread novel diseases the world over. Today’s COVID-19 pandemic is no different that’s why a lot of us are worried about the risks of getting sick in an airplane. Charlotte Ryan and Naomi Kresge have answers to key questions about the safety of air travel as some countries are now reopening for business and relaxing travel restrictions. If you think about it, the same questions apply to other modes of mass transportation such as buses and trains where a lot of people spend a lot of time in an enclosed environment.

Why children avoid the worst coronavirus complications might lie in their arteries link

Children have less severe forms of COVID-19 compared to adults, especially those with diabetes and hypertension. The main difference, according to Frank Ruschitzka a cardiologist at the University Hospital Zurich in Switzerland, may lie in the endothelium that lines the blood vessels which are in better condition in children compared to in adults. Healthier endothelium is able to withstand infection from SARS-CoV-2 which avoids the devastating blood clotting often seen in adult patients.

Paul Monagle, a pediatric hematologist at the Melbourne Children’s Campus has a similar theory. He thinks that when SARS-CoV-2 invades endothelial cells, it disrupts communication between such cells, platelets, and plasma components that results in excess clot formation which could result in death.

Can existing live vaccines prevent COVID-19? link | link

A group of experts has made the argument that the polio vaccine should be tested against COVID-19 because it strengthens the immune system against a wide range of diseases aside from polio. It’s fairly recent and existing polio vaccine are not included in current trials by WHO and other health experts in their race to find a safe and effective vaccine against SARS-CoV-2.

How to handle a pepper spray attack – link

The ingredients that go into pepper sprays are not regulated by the US government. Manufacturers have their own blend and the ingredients are not printed on labels. This means there’s little that scientists know about its composition so they can’t really say how harmful it can be. I’ve had a whiff of tear gas before way back when my sister and I were still kids when we found a small canister in my aunt’s purse. It was a nightmare and they say pepper sprays are far worse. Yikes!

Death of the Office – link

Before Google and other tech start-ups started the fad of open office spaces with slides, bean bags, and free snacks, the ancient Romans as it turns out were on a league of their own. As they dedicated more time to leisure ‘work’ was wherever and whenever they were not having fun. It’s an interesting overview of the origins and evolution of the office. Something we all miss somehow as we work from home due to the pandemic.
