Medicine: Why Long Covid Is Still Not Understood

Even mild COVID-19 is at least correlated with a startlingly wide spectrum of seemingly every illness. We need a much better taxonomy to address people’s suffering.

Long Covid – Whole Body Symptoms

From The Atlantic, October 5, 2022:

The cases of long covid that turn up in news reports, the medical literature, and in the offices of doctors like me fall into a few rough (and sometimes overlapping) categories. The first seems most readily explainable: the combination of organ damage, often profound physical debilitation, and poor mental health inflicted by severe pneumonia and resultant critical illness.

This serious long-term COVID-19 complication gets relatively little media attention despite its severity. The coronavirus can cause acute respiratory distress syndrome, the gravest form of pneumonia, which can in turn provoke a spiral of inflammation and injury that can end up taking down virtually every organ. I have seen many such complications in the ICU: failing hearts, collapsed lungs, failed kidneys, brain hemorrhages, limbs cut off from blood flow, and more. More than 7 million COVID-19 hospitalizations occurred in the United States before the Omicron wave, suggesting that millions could be left with damaged lungs or complications of critical illness. Whether these patients’ needs for care and rehabilitation are being adequately (and equitably) met is unclear: Ensuring that they are is an urgent priority.

Covid-19: The Best Ways To Avoid Virus Transmission

Covid-19: ‘The Variant Hunters’ – Understanding Its Spread (Cambridge)

The variant hunters are helping us to understand how and why the COVID-19 virus is spreading, allowing us to fight back against the COVID-19 pandemic.

Hear from some of the scientists behind the UK’s nationwide sequencing effort to track SARS-CoV-2. Sir Patrick Vallance (the government’s Chief Scientific Adviser) also describes how the expertise that came together during the pandemic is now recognised across the world – and why it’s crucially important to continue to sequence to be ready for future pandemics.

This pioneering work is being carried out by the COVID-19 Genomics UK (COG-UK) consortium, which comprises numerous academic institutions, four public health agencies and the Wellcome Sanger Institute, and is administered by the University of Cambridge.

“Incredibly impressive, incredibly high quality and incredibly focused on the mission to make sure that as many people benefited from the science as possible,” Sir Patrick Vallance.

Science & Medicine: Story Behind The mRNA Vaccines

As mRNA-based COVID-19 vaccines are deployed to protect hundreds of millions of people across the world from the deadly global pandemic, the University of Pennsylvania scientists whose research breakthroughs laid the foundation for swift vaccine development have been awarded the 2021 Lasker-DeBakey Clinical Medical Research Award. Here, mRNA vaccine pioneers Drew Weissman, MD, PhD, and Katalin Karikó, PhD, share the story behind their development of this groundbreaking technology, and what it means for the future of medicine.

Harvard: ‘Nanobodies’ Evolved From Synthetic Antibody Fragments

A new approach developed by Harvard Medical School researchers uses yeast to rapidly evolve synthetic antibody fragments called nanobodies with the aim to find variants that are effective at binding to selected antigens, including SARS-CoV-2. The antibodies are intended for use in diagnostic tests and disease treatments. Read the full story: https://hms.harvard.edu/news/antibody…

Morning News: New China Coronavirus Lab-Leak Probe, Latin America Slump

The suggestion that the virus first emerged from a Chinese laboratory has proved stubbornly persistent; as calls mount for more investigation, it has become a potent epidemiological and political idea.

Latin America’s strict lockdowns have had the expected calamitous economic effects. We look at the region’s prospects for recovery. And the tricky business of artificially inseminating a shark.
