Study estimates 2 COVID vaccine doses 40% effective against emergency, hospital care in young kids

Two doses of a COVID-19 mRNA vaccine were 40% effective against emergency department (ED) visits and hospitalization in preschool-aged children during a period of Omicron variant predominance, estimates a test-negative, case-control study using data from the New Vaccine Surveillance Network (NVSN).

It’s not the quarantine that made so many other diseases surge: It’s the COVID

The world is nearly four years into the COVID-19 pandemic, but how the SARS-CoV-2 virus damages human lives, both in the short term and across a span of years, is still becoming clear. Earlier this month, a study in Lancet showed that 54% of those infected in the first months of the pandemic were still experiencing symptoms over three years later.

Cancer patients with COVID at higher risk of death, hospitalization amid Omicron

A study from Israel finds that adult solid-cancer patients had a higher risk of death and hospitalization after COVID-19 infection than infected patients without cancer during a period of Omicron variant predominance and that vaccination lowered that risk.

Study: Spike in premature births caused by COVID, halted by vaccines

COVID-19 caused an alarming surge in premature births, but vaccines were key to returning the early birth rate to pre-pandemic levels, according to a new analysis of California birth records.

“The effect of maternal COVID infection from the onset of the pandemic into 2023 is large, increasing the risk of preterm births over that time by 1.2 percentage points,” says Jenna Nobles, a University of Wisconsin–Madison sociology professor. “To move the needle on preterm birth that much is akin to a disastrous environmental exposure, like weeks of breathing intense wildfire smoke.”

Study: Air purifier use at daycare centres cut kids’ sick days by a third

Use of air purifiers at two daycare centres in Helsinki led to a reduction in illnesses and absences among children and staff, according to preliminary findings of a new study led by E3 Pandemic Response.

Air purifiers of various sizes and types were placed in two of the city’s daycare centres during cold and flu seasons.

The initial results from the first year of research are promising, according to researcher Enni Sanmark, from HUS Helsinki University Hospital.

“Children were clearly less sick in daycare centres where air purification devices were used — down by around 30 percent,” Sanmark explained.

Air Pollution Is Really Dangerous, Even More New Evidence Shows

PM2.5 particles are tiny enough to enter the bloodstream and lodge in the lungs, where they contribute to respiratory problems such as asthma. They also can prompt heart attacks and strokes. And they have been linked to diabetes, obesity and dementia and may exacerbate COVID.

Inside long COVID’s war on the body: Researchers are trying to find out whether the virus has the potential to cause cancer

Long COVID is no stranger to either patients or those immersed in studies of its effects. In the U.S., one in 7 adults–about 14% of the adult population–has experienced symptoms that lasted three months or longer after first contracting the virus. The worldwide estimate for long COVID is 65 million people.

What is less clear–because it’s still so early in the process–is the impact of some of SARS-CoV-2’s most dangerous characteristics on those hit by long COVID. But some researchers are warily watching for the worst: a potential connection to cancer.

MRI study spotlights impact of long COVID on the brain

A new study comparing magnetic resonance imaging (MRI) images of patients with long COVID, fully recovered COVID-19 survivors, and healthy controls shows microstructural changes in different brain regions in the long-COVID patients. The findings will be presented next week at the annual meeting of the Radiological Society of North America.

Omicron, Now 2 Years Old, Is Not Done With Us Yet

By November 2021, nearly two years after the coronavirus emerged in Wuhan and spread across the world, the surprises seemed to be over. More than four billion people had been vaccinated against the virus, and five million had died. Two new variants, known as Alpha and Delta, had surged and then ebbed. As Thanksgiving approached, many Americans were planning to resume traveling for the holiday.

And then, the day after turkey, the pandemic delivered a big new surprise.

‘This isn’t a life’: The crushing burden of Long Covid

Ashleigh was saving up to travel overseas in the near future. Now, she’s housebound at 28, sometimes even bedbound, unable to drive or walk more than a short distance. “My mum has had to take care of me a lot this year, and I feel a bit bad for her experience as well.”

Michael, 32, was a busy Crown prosecutor. Now he’s been disabled for more than 18 months, taking long stretches off work and struggling with his mental health and damaged relationships. “It’s probably the worst thing that’s ever happened to me.”

A Lot of Deer Carry COVID. Should That Worry People?

COVID hasn’t just colonized billions of humans. The virus has entered North America’s white-tailed deer populations, transforming one of the largest remaining wild mammal populations on Earth into another rapidly evolving reservoir for COVID.

Substantial decrease noted in severe respiratory illness during first 2 years of pandemic

Compared to the 3 years prior to the pandemic, children with medically complex conditions and otherwise healthy children saw decreases in severe non-COVID respiratory illnesses in 2020 and 2021, the authors of a study yesterday note in JAMA Network Open.

The cross-sectional study, based on 139,078 respiratory hospitalizations in Canada, shows that the mitigation efforts used during the first several months of COVID-19 likely prevented serious outcomes from respiratory illness complications, including hospitalizations, intensive care unit (ICU) admissions, and death.

COVID increased gender life expectancy gap in US

For more than 100 years, American women have outlived American men, largely due to differences in rates of cardiovascular disease and lung cancer. Now COVID-19 has widened the gendered life expectancy gap, according to a research letter published yesterday in JAMA Internal Medicine.

Can’t Think, Can’t Remember: More Americans Say They’re in a Cognitive Fog

There are more Americans who say they have serious cognitive problems — with remembering, concentrating or making decisions — than at any time in the last 15 years, data from the Census Bureau shows.

The increase started with the pandemic: The number of working-age adults reporting “serious difficulty” thinking has climbed by an estimated one million people.
