COVID-19 is associated with weakness disorders. Documented vaping risk


(Reuters)-The following is a summary of some of the latest scientific research on the new coronavirus and efforts to find cures and vaccines for the virus-caused disease COVID-19.

Neuromuscular disease can be caused by COVID-19

The researchers added the weakness disorder myasthenia gravis to the list of neurological problems associated with severe COVID-19. Tremor, seizures, disturbances of consciousness and other nervous system problems are already associated with severe COVID-19. In some cases, the virus appears to trick the body into attacking the brain by triggering the immune system to produce so-called autoantibodies. It is an autoantibody that incorrectly targets its own tissues and organs. In myasthenia gravis, autoantibodies attack nerve connections to the muscles, causing skeletal muscles, including breathing and moving parts of the body, to weaken after activity. Physicians on Monday in the Annals of Internal Medicine in three patients without previous neuropathy or autoimmune disease who had symptoms of myasthenia gravis within a week of the onset of COVID-19-related fever. I explained. The time from coronavirus infection to the onset of symptoms of myasthenia gravis “is consistent with the time from infection to symptoms of other neurological disorders caused by the infection,” the researchers said. They also add that the findings add to the “increasing evidence of other neuropathy with putative autoimmune mechanisms after the onset of COVID-19.” (

Deaeration by young people associated with increased COVID-19 risk

Vaping appears to be associated with a significantly increased risk of getting COVID-19 among teens and young adults in the United States. The researchers analyzed national survey data collected in May from 4,351 participants aged 13 to 24 published in the Journal of Adolescent Health on Tuesday. People who used both cigarettes and e-cigarettes in the last 30 days were 4.7 times more likely to report having experienced COVID-19 symptoms than those who did not smoke or smoke. Of those who tested COVID-19, those who used only e-cigarettes were five times more likely to report a positive test. Individuals who have used both e-cigarettes and cigarettes were seven times more likely to be diagnosed with COVID-19. Dr. David Christiani of Harvard TH Chan School of Public Health, who was not involved in the study, told Reuters that there are many reasons why Vape people are at increased risk of acquiring COVID-19. “Evaporating fluids impair local immunity in the nose and the rest of the respiratory tract, if these defenses are compromised, people will be more susceptible,” the study said. The authors of the study also state that vaping involves repeated mouth and face contact associated with the virus and its spread. (;

Face masks may one day help diagnose a disease

Some face masks are effective in limiting the spread of COVID-19, while others are not, while others may help diagnose conditions unrelated to coronaviruses. Researchers reported in Science Advances that the N95 mask is most effective unless it has a valve that allows the wearer’s breath to escape. The most effective is the surgical mask, followed by the multi-layer cotton mask. Bandanas minimize the escape of exhaled droplets. The fleece fabric, worn around the neck and pulled over the face, “looked like the largest droplets were dispersed into a large number of smaller droplets,” resulting in a longer dwell time in the air, which It can be effective.” Another report in the journal Analytical Chemistry suggests that while molecules in the breath may reveal disease, they need to be inhaled into tubes or bags to collect enough molecules to diagnose the problem It is explained. However, certain types of fiber inserts placed inside the mask are able to collect sufficient molecules during the normal activity of the wearer. After volunteers put on a mask with inserts and use mass spectrometry to inspect the fiber inserts, researchers can even see traces of particles in the breath. (;

Certain immune responses may contribute to severe COVID-19

Researchers comparing the innate immune response (the body’s first line of defense) between patients with coronavirus infections and healthy people have discovered several differences that may shed light on COVID-19 and why some I found that the case of will become so serious. For example, there were differences in the amount and function of different cell types in the blood, the gene activity of cells isolated from the blood, and the level of inflammatory molecules. In particular, three molecules elevated in critically ill patients, called LIGHT, Oncostatin-M, and EN-RAGE, are associated with lung inflammation, but have not been previously seen in COVID-19 patients. .. The blood of critically ill patients also contained bacterial debris, such as bacterial DNA and cell wall material. The more debris, the worse the patient’s condition and the more inflammatory substances circulate in the blood. Surprisingly, however, “the plasma levels of inflammatory molecules were elevated, but the blood cells themselves were sluggish and unable to respond efficiently to stimuli,” said Stanford’s lead author. Bali Planlen told Reuters. Overall, Pulendran says, “This study has provided insights into the mechanisms of COVID-19 and potential therapeutic targets.” (
