July 14 (Reuters) – The following is a summary of some recent studies on COVID-19. They come with studies that deserve further examination to corroborate the effects and have yet been rated through peer review.
High-pressure oxygen treatment can help prolong COVID
COVID patients for a long time would possibly see some improvement after breathing natural oxygen in a high-tension air environment, according to data from a small Israeli trial.
The researchers randomly assigned 73 patients with post-COVID symptoms who lasted at least 3 months to receive hyperbaric oxygen (HBO) treatment or a dummy treatment. Patients from the HBOT organization spent 40 sessions breathing natural oxygen in a chamber where the atmospheric stress was two to three. times higher than normal, allowing the lungs to get more oxygen than they would. Shortly after the last treatment, the HBOT organization showed “significant improvement” over the fictional organization in terms of thinking ability, energy, sleep, psychiatric symptoms and pain, according to a report published Tuesday in Scientific Reports https://www. natureArraycom/articles/s41598-022-15565-0. Symptomatic improvement was related to magnetic resonance imaging evidence of structural and functional healing of the brain and an improved oxygen source. “Bringing blood to the brain,” the researchers said.
HBOT is used to treat wounds that do not heal well and has recently been tested as a remedy for traumatic brain injury, however, this is the first randomized trial to test it over a long period of time for COVID. Larger studies are needed to verify the findings and identify patients who might benefit, the researchers said.
Previous Omicron infection would possibly oppose BA. 4/BA. 5
Young and middle-aged adults who have become inflamed with earlier versions of the Omicron variant of the coronavirus likely have “strong” coverage opposed to reinfection through the newly dominant Omicron BA. 4 and BA. 5 subvariants, according to the researchers. .
This would not be the case if they were infected with a variant circulating before Omicron, according to a Qatari study. impression of having only 15. 1% efficacy in preventing symptomatic reinfection of BA. 4/BA. 5 and 28. 3% efficacy in preventing any reinfection of BA. 4/BA. 5. -BA. 4/BA. 5 infection and 7 nine. 7% effectiveness against any BA. 4/BA. 5 reinfection. The study did not assess the severity of reinfection. In a report published in medRxiv on Tuesday https://www. medrxiv. org/content/10. 1101/2022. 07. 11. 22277448v1 Before the peer review, the researchers note that the findings would possibly not apply to older people, given that in Qatar only nine% of citizens are over the age of 50.
The study also showed that coverage against infections with earlier variants of pre-Omicron decreases against BA. 4/BA. 5 than against BA. 1/BA. 2, “indicating that these two new variants have a greater ability to evade the immune system response,” said study leader Laith Jamal Abu Raddad of Weill Cornell Medicine-Qatar.
COVID-19 vaccines lasted longer for some women
COVID-19 vaccination may be linked to short-term menstrual cycle lengthening in some women, according to a new study.
The effects come from 3858 nurses in the U. S. U. S. and Canadian governments have completed age questionnaires twice a year since 2011. By December 2021, 91% of them had been vaccinated against the coronavirus. Before the pandemic, 15% reported abnormal cycles; which rose to 22. 7 in 2021, the researchers reported Wednesday in the American Journal of Obstetrics.
“A general menstrual cycle is characterized by tightly regulated inflammatory and immune mediators” that can be affected by the body’s immune reaction to vaccines, the researchers said. They call for tracking the “fitness of the menstrual cycle in clinical trials of vaccines and greater attention to sex. “differences based on reaction to the vaccine. “
