Bloomberg COVID-19 Podcast: Why New York Got Hit So Hard

At least 21,000 New Yorkers are dead from Covid-19, with a few dozen added to the city’s count every day. The city’s deaths are 10 times those of Los Angeles County’s. They’ve surpassed the 16,000 lives lost in Italy’s hard-hit Lombardy region. Drew Armstrong reviewed the statements of experts, officials, and politicians to better understand the root causes of New York City’s devastating outbreak.

Will Warm Weather Slow Spread of Novel Coronavirus? – NIH Directors Blog

With the start of summer coming soon, many are hopeful that the warmer weather will slow the spread of SARS-CoV-2, the novel coronavirus that causes COVID-19. There have been hints from lab experiments that increased temperature and humidity may reduce the viability of SARS-CoV-2. Meanwhile, other coronaviruses that cause less severe diseases, such as the common cold, do spread more slowly among people during the summer.

6 Health Workers Talk About Their Battles With the Pandemic – Wired

HEALTH CARE WORKERS the world over have never faced combat with anything quite like Covid-19, a disease that spreads rapidly and so far has killed more than 360,000 people worldwide. Health officials were so concerned that hospitals would be overwhelmed by patients that in March much of the world went into an unprecedented lockdown to “flatten the curve,” or to slow the rate of new infections to give facilities time to muster a response. Regions that acted quickly, like the San Francisco Bay Area, have so far succeeded—those that stalled, like New York City, saw their hospitals flooded with patients. It got so bad in NYC that one hospital had to bring in a refrigerated semi-truck trailer to hold the dead.

15 West Point Cadets Test Positive for Coronavirus – New York Times

At least 15 of the graduating cadets who returned to West Point ahead of President Trump’s commencement speech in June tested positive for the coronavirus, according to a U.S. Army spokeswoman. None of those cadets had coronavirus symptoms, and the virus had not spread from them to any other cadets among the class of 1,106 since they returned to the U.S. Military Academy last week, the spokeswoman, Col. Sunset Belinsky, said on Tuesday. She said that the academy learned that the 15 had the coronavirus after all cadets were tested immediately upon arriving on campus. The cadets who tested positive were immediately isolated. [If the link above does not work, try this one]

 

Clinical Considerations

Why coronavirus hits men harder: sex hormones offer clues – Science Magazine

In January, one of the first publications on those sickened by the novel coronavirus in Wuhan, China, reported that three out of every four hospitalized patients were male. Data from around the world have since confirmed that men face a greater risk of severe illness and death from COVID-19 than women and that children are largely spared. Now, scientists investigating how the virus does its deadly work have zeroed in on a possible reason: Androgens—male hormones such as testosterone—appear to boost the virus’ ability to get inside cells.

Blood vessel attack could trigger coronavirus’ fatal ‘second phase’ – Science

Frank Ruschitzka told his pathologist to be ready before the first COVID-19 patient died. In early March, Ruschitzka, who leads the cardiology department at University Hospital Zürich, noticed that patients with the disease had strange symptoms for what was then thought to be chiefly a respiratory infection. Many patients had acute kidney failure, organ damage, and mysterious blood clots. Several weeks later, the first body was autopsied: Tiny clots and dead cells littered the capillaries of the lungs, and inflammation had distended blood vessels supplying every organ in the body.

Infection with SARS-CoV-2 causes abnormal laboratory results of multiple organs in patients – Aging

Elevated neutrophil-to-LYM ratio (NLR), D-dimer(D-D), interleukin (IL)-6, IL-10, IL-2, interferon-Y, and age were significantly associated with the severity of illness. However, significant and sustained decreases were observed in the LYM subset (p<0.05). D-D, T cell counts, and cytokine levels in severe COVID-19 patients who survived the disease gradually recovered at later time points to levels that were comparable to those of mild cases. Second, D-D increased from 0.5 to 8, and the risk ratio increased from 2.75 to 55, eventually leading to disseminated intravascular coagulation. Moreover, the acute renal function damage occurred earlier than abnormal heart and liver functions (p<0.05).

Mental Health Issues After COVID-19 May Require Additional Care – Med Page Today

It is early days in terms of evaluating the long-term mental health effects of the COVID-19 pandemic, but there may be lessons to be learned from preceding diseases caused by closely related human coronaviruses. Biologically speaking, such a comparison makes sense, because SARS-CoV-2, which causes COVID-19, resembles MERS-CoV (>50% similarity) and SARS-CoV (>79% similarity). Even the spike protein that attaches to the angiotensin-converting enzyme 2 receptor to hijack human cells is largely similar.

What Experts Know About a Rare Inflammatory Syndrome Linked to COVID-19 – Smithsonian

As the COVID-19 pandemic spreads, reports of new and unusual symptoms are on the rise. The latest side effects of a novel coronavirus infection range from nerve damage to “COVID toe.” In rare cases, COVID-19 seems to cause severe inflammation in children.

Pulmonary embolism and COVID-19 – Science Direct

Researchers say early diagnosis of a life-threatening blood clot in the lungs led to swifter treatment intervention in COVID-19 patients. A new study finds that 51 percent of patients found to have a pulmonary embolism, or PE, were diagnosed in the Emergency Department, the entry point for patients being admitted to the hospital.

Pulmonary Complications Common in Surgery Patients With COVID-19 – MedPageToday

Pneumonia and other pulmonary complications occurred in half of postsurgical patients with perioperative COVID-19 in an international study, and these complications were associated with a higher risk for early death. [Related Lancet Paper]

An integrated national scale SARS-CoV-2 genomic surveillance network – The Lancet

The Coronavirus Disease 2019 (COVID-19) Genomics UK Consortium (COG-UK) was launched in March, 2020, with £20 million support from UK Research and Innovation, the UK Department of Health and Social Care, and Wellcome Trust. The goal of this consortium is to sequence severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) for up to 230 000 patients, health-care workers, and other essential workers in the UK with COVID-19, which will help to enable the tracking of SARS-CoV-2 transmission, identify viral mutations, and integrate with health data to assess how the viral genome interacts with cofactors and consequences of COVID-19.
