Public Health should offer N95 masks

Re: Heavy smoke, smog wallop Ottawa, cancelling Dragon Boat, Indigenous festivals, June 25.

Thanks to climate change, we’re experiencing unprecedented hazardous air quality. Concentrations of pollutants have been an order of magnitude greater than the levels in major cities. And more smoke is on the way.

Ottawa Public Health should follow the example of public health organizations in other cities: it should distribute N95 respirators to Ottawa residents. Huron Perth Public Health is now offering respirators to residents who are at high risk for respiratory issues.

Study: Sperm counts decline even after mild COVID infections

Men recently infected with COVID-19 have decreased sperm counts for more than 3 months following even mild infections, and the sperm they do produce is less able to swim, according to new findings presented today at the annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) in Denmark.

The findings are intriguing because men produce new sperm every 2 or 3 months, and the findings are based on semen analyses taken after 100 days, suggesting COVID does long-term damage to the male reproductive tract.

‘Bold’ study that gave people COVID reveals ‘supershedder’ phenomenon

A study of people who were intentionally infected with SARS-CoV-2 has provided a wealth of insights into viral transmission — showing, for example, that a select group of people are ‘supershedders’ who spew vastly more virus into the air than do others.

New imaging technique captures COVID-19’s impact on the brain

Some may think COVID-19 affects just the lungs. What was found is that this new MRI technique that we created is very good at identifying changes to the brain due to COVID-19. COVID-19 changes the white matter in the brain.

Study: At-Home Rapid COVID Tests May Miss Many Infections

According to a new study, rapid antigen tests may provide false negatives — suggesting that a person is infection-free, even though other parts of their respiratory tract are teeming with the virus. The researchers found that most people showed a delay of several days between when the virus first appeared in the throat or saliva and when it appeared in the nose. Importantly, 15 of the 17 study participants had high levels of the virus for at least a day prior to getting a positive result.

Covid-19: Metformin reduces the risk of developing long term symptoms by 40%, study finds

Metformin—a cheap, safe, and widely available diabetes drug—could reduce the incidence of long covid if given during the acute phase of covid-19, a new study indicates.

A two week course of metformin given within three days of testing positive for SARS-CoV-2 led to 40% fewer long covid diagnoses over the following 10 months compared with people who had taken placebo, according to a randomised controlled trial.

Could fused neurons explain COVID-19’s ‘brain fog’?

Researchers have demonstrated that a SARS-CoV-2 infection can induce brain cells to fuse together, with severe impacts on the functioning of neurons. Neurons may fuse together with other neurons or glia, and larger multicellular syncytia may be formed. The fusion of neurons may be one of the causes of the cognitive issues associated with COVID-19.
