Restrictions likely helped curb spread of COVID-19 in N.S., Dalhousie researchers find

A new report from six Dalhousie University researchers has found government restrictions that limited movement during the first two years of the pandemic likely helped curb the spread of COVID-19.

It also found infection, hospitalizations and deaths increased when restrictions eased and the highly infectious Omicron variant arrived.

COVID patients exhale up to 1,000 copies of virus per minute during first eight days of symptoms

COVID patients exhale high numbers of virus during the first eight days after symptoms start, as high as 1,000 copies per minute, reports a new Northwestern Medicine study.

High levels of 2 blood-clotting proteins may portend post-COVID brain fog

High levels of two blood biomarkers during infection could predict cognitive dysfunction, or “brain fog,” among COVID-19 survivors 6 and 12 months after hospitalization, according to a UK study published yesterday in Nature Medicine.

Blood Clotting Proteins Might Help Predict Long COVID Brain Fog

Many people who have long COVID—a condition in which health issues persist months after infection—report struggling with “brain fog,” recurring memory and concentration lapses that make it difficult­­ to function in everyday life. Now a new study has found these cognitive problems could result from blood clots triggered by infection, possibly through mechanisms like those that cause some types of dementia. These clots leave telltale protein signatures in blood, suggesting that testing for them could help predict, diagnose and possibly even treat long COVID.

COVID infection risk rises the longer you are exposed — even for vaccinated people

Prolonged exposure in close proximity to someone with COVID-19 puts people at high risk of catching the disease, even if they’ve had both the disease and vaccinations against it, a study shows.

Long COVID is debilitating children. Doctors worry there aren’t enough centers to treat them

Last month, the National Institutes of Health updated its considerations for long COVID to say the burden of the condition in children “may be quite large.” Studies estimating its prevalence in pediatric populations are limited and conflicting, estimating up to 25% of children infected with the SARS-CoV-2 virus could go on to develop long COVID, though it’s more likely between 2% and 10%. Older children with existing chronic diseases or who had a more severe COVID-19 infection have an increased risk.

Existential crisis: how long COVID patients helped us understand what it’s like to lose your sense of identity and purpose in life

This isn’t who I am – I don’t recognise myself. I panic if I get on the Tube and there’s no seat. It’s a very strange feeling, like not being in your own body. My fear is I’ll never really get better, and that I’m always going to be at 70% of my former self.

Opinion: Study shows ‘long COVID’ likely to cause mass misery if treatments can’t be developed

Given that 103 million Americans and 770 million people worldwide have been diagnosed as having contracted COVID-19, a future of misery could await a stunningly large cross-section of humanity.

Study: Oximeters often overestimate COVID patients’ oxygen levels, delaying care

“These results suggest that although racial and ethnic disparities exist in measurement of oxygen saturation by pulse oximetry, overestimation may increase the risk of hospital readmission regardless of patient race.”

What Canada’s newest COVID data shows us about the toll of Omicron

The latest snapshot of Canada’s battle against the pandemic captures the toll the Omicron variant has taken on the elderly.

The highly infectious variant drove up hospitalizations across Canada, especially in those age 65 and older, according to data released Wednesday from the Canadian Institute for Health Information.

Halifax researcher seeks COVID-19 long haulers to study effects of virus on brain

Dr. Carlos Hernandez is an assistant professor in Dalhousie University’s faculty of computer science. He hopes to contribute to long COVID research in collaboration with scientists at Western University in London, Ont., and the National Autonomous University of Mexico in Mexico City in a multi-year study assessing cognitive damage caused by the condition.

But there’s just one issue: He needs more participants in the Halifax area.

COVID-19 hospitalizations jump nearly 20% year-over-year, ICU and ER visits down, data show

Across the country, hospital emergency departments and intensive care units have seen a decline in COVID-19 patients compared with a year ago, but the number of people admitted to hospital because of the virus has increased nearly 20 per cent, according to new data from the Canadian Institute for Health Information.

SARS-CoV-2 can cause lasting damage to cells’ energy production

At the beginning of the COVID-19 pandemic, the virus responsible for the disease, SARS-CoV-2, was feared for its devastating damage to the lungs. But it quickly became apparent that the virus can infect organs and tissues throughout the body, including the heart, brain, kidneys, and blood vessels.

Much of the resulting dysfunction was thought to be the result of inflammation, the immune system’s response to infection. But research has suggested that effects on mitochondria may also play a role in organ damage from SARS-CoV-2 infection. Mitochondria are the powerhouses of cells, producing most of the energy they need.

Long COVID still worrisome 2 years after infection

Our findings highlight the substantial cumulative burden of health loss due to long COVID and emphasize the ongoing need for health care for those faced with long COVID. It appears that the effects of long COVID for many will not only impact such patients and their quality of life, but potentially will contribute to a decline in life expectancy and also may impact labor participation, economic productivity, and societal well-being.
