Science Magazine – May 12, 2023 issue: Scalloped hammerhead sharks (Sphyrna lewini) form daytime schools near the ocean’s surface and, at night, dive into cold, deep waters to hunt deep-sea prey. They keep warm while deep diving by closing their gills—effectively holding their breath.
The October 21, 2022 cover story this week steps back from the news agenda to explore the impact of living with long Covid. For millions of people worldwide who have survived initial infection with the virus, recovery is slow. Symptoms such as breathlessness, fatigue and loss of smell or taste persist for months and, as our science editor Ian Sample explains, treatments that work for some may not be successful for others.
This week delegates to the Chinese Communist party’s 20th congress are in Beijing where they are expected to rubber stamp Xi Jinping’s historic third term as leader. Our big story looks at what the president’s supremacy means for the country and its closest neighbour – Taiwan – which lives in the shadow of Xi’s avowed intention to bring the island back under China’s tutelage.
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.
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.
The vaccine, called Convidecia Air, changes the liquid form of the vaccine into an aerosol using a nebuilzer. The vaccine can then be inhaled through the mouth using the nebulizer machine. The needle-free vaccine “can effectively induce comprehensive immune protection in response to SARS-CoV-2 after just one breath,” Cansino said in a statement.
Fortune.com on September 5, 2022 – China’s government approved the world’s first inhaled vaccine against COVID-19, the vaccine’s maker Cansino Biologics announced on Sunday.
In July, Chinese scientists published a pre-print study showing that people who received one booster dose of Cansino’s inhaled vaccine after two doses of the inactivated jab from Chinese maker Sinovac developed more antibodies than people who received three Sinovac shots. Four weeks after receiving the inhaled booster, 92.5% of people had developed neutralizing antibodies for Omicron.
Those who got three doses on Sinovac’s jab did not demonstrate any neutralizing antibodies for Omicron, either four weeks or six months after getting a booster.
