Comments closedOur study shows that markers of brain injury are present in the blood months after COVID-19, and particularly in those who have had a COVID-19-induced brain complication (e.g. inflammation, or stroke), despite resolution of the inflammatory response in the blood. This suggests the possibility of ongoing inflammation and injury inside the brain itself which may not be detected by blood tests for inflammation.
The fall in occupancy rates in Quebec’s emergency rooms that began on 19 December ended on Tuesday.
The Index Santé website noted that this average rate had risen to 95% on 26 December, before jumping to 112% on Wednesday morning, shortly before 6 a.m., which was considered very high.
Comments closedAnother long-term effect of the novel coronavirus appears to be a higher chance of patients contracting Alzheimer’s disease in the years to follow, according to the latest research.
Numerous large research projects overseas have shown a link between COVID-19 and cognitive disorders, along with Alzheimer’s.
“The novel coronavirus is a new risk factor for dementia,” said Takayoshi Shimohata, a neurology professor at Gifu University, who also serves on the health ministry’s editorial committee that compiles a manual for treating COVID-19’s aftereffects. “There needs to be greater understanding that the illness also affects the brain.”
Comments closedThe number of people in Waterloo region who have received their most recent COVID-19 booster shot is just under 11 per cent, which is below the national average.
The region’s vaccination dashboard shows 10.9 per cent of people in the community are up-to-date on their vaccinations as of Dec. 7. The region notes “up to date” means a person has completed their primary series and received a booster dose within the previous six months.
The number of people who have received the updated XBB.1.5 COVID-19 vaccine sits at 10.8 per cent, the region told CBC News in an email.
Comments closedAfter contracting COVID-19, patients may have higher risk of heart failure from persistent viral infection in their hearts, even without developing notable heart disease, according to study results announced by Japanese researchers on Dec. 23.
The team including researchers from Riken, Japan’s largest scientific institute, pointed out the possibility of a “heart failure pandemic” in the near future, and is stressing the need for countermeasures.
Comments closedBTNX, the Canadian rapid test supplier that won an estimated $2 billion in federal contracts, denied that Health Canada used BTNX’s edited study to evaluate the rapid test kit that the federal government later purchased.
A year-long investigation into federal procurement published by Global News on Thursday revealed that Toronto area-based BTNX deleted dozens of specimens, or samples, from a study it submitted to Health Canada. That evaluation showed how well the company’s test detected COVID-19.
Comments closedThe B.C. Centre for Disease Control published its final respiratory illness data of the year this week, reporting continued increases in transmission of influenza and RSV, while COVID-19 levels remain stable.
There were 153 people hospitalized with COVID as of Thursday, a decrease from the last time that number was reported two weeks ago.
The number of new, lab-confirmed COVID-19 infections also declined in the latest update, though test positivity remained unchanged, indicating the decline was due to fewer government-funded tests being performed.
Comments closedThe U.S. Centers for Disease Control and Prevention (CDC) said on Friday that COVID subvariant JN.1 accounts for 39% to 50% of cases in the United States as of Dec. 23, according to the agency’s projections.
Comments closedThe new COVID-19 variant that scientists call JN.1 now makes up about 44.1% of COVID-19 cases across the country, the Centers for Disease Control and Prevention estimated Friday, marking another week of the fast-spreading variant’s steep rise in the U.S.
The increase is more than two times larger than the 21.3% that the CDC now estimates the strain made up of infections for the week ending Dec. 9, after Thanksgiving.
Comments closedThe severity of the infection doesn’t seem to make a difference. These complications can occur even in people who have very mild symptoms. The big surprise is how much this can affect younger people. Studies are showing that even young, active people can experience heightened risk of these complications.
High blood pressure, high cholesterol, diabetes, obesity: These are some of the well-known risk factors that can put people at heightened risk for heart attack and stroke.
Now some health experts say COVID-19 should be added to that list.
Comments closedOn December 23, a research team from Riken and other institutes announced the results of a study showing that after infection with the novel coronavirus, the heart may be persistently infected with the virus and the risk of heart failure may increase, even if the patient does not develop noticeable heart disease. The team points to the possibility of a sharp increase in the number of heart failure patients in the near future and calls for countermeasures to be taken.
Infection with the novel coronavirus occurs when a protruding “spike protein” on the surface of the virus binds to the ACE2 receptor on the surface of human cells. According to the team, the heart is more likely to express ACE2 compared to other organs. It has also been reported that some people infected with the novel coronavirus have reduced cardiac function, but the detailed mechanism is not known.
Comments closedNova Scotia has reached a solemn milestone, surpassing 1,000 COVID-19 deaths since the beginning of the pandemic.
“A thousand people in a province of a million people is a lot of humans and families that are missing people,” said Dr. Lisa Barrett, an infectious diseases doctor and researcher at Dalhousie University in Halifax.
Data released in the latest weekly respiratory watch report shows an additional nine deaths for the week of Dec. 10-16, bringing the total to 1,004 in the province.
Comments closedWith COVID-19 cases and other respiratory illnesses rising across the region, some area hospitals have begun to bring back face mask requirements to halt the spread of infections.
Boston Medical Center said Thursday it would resume masking requirements in all patient-care areas beginning Friday. On Monday, the Dana-Farber Cancer Institute reinstated its mask requirements in all clinical and public spaces, and the Beth Israel Lahey Health system (BILH) updated its policies to require masking for all health care personnel upon entry to a patient room or bed space.
Comments closedStaffing shortages will close a Hamilton urgent care centre for two days at the same time city emergency departments are becoming increasingly congested with flu, COVID-19 and RSV patients.
With just 13 per cent of Hamiltonians getting a COVID shot in the past six months, local hospitals are bracing for the viral surge to continue climbing over the holidays.
Comments closedSnow might not be swirling in the UK but Covid is in the air this Christmas, data has revealed, with experts warning a new variant is on the rise around the world.
According to data from the Office for National Statistics (ONS) and the UK Health Security Agency (UKHSA), an estimated 4.2%, or one in 24 people, in England and Scotland had Covid on 13 December compared with 1.8% – or one in 55 – on 29 November.
