Small study finds brain alterations after COVID Omicron infection
Researchers in China report thinning of the gray matter and other changes in certain parts of the brain in 61 men after COVID-19 Omicron infection.
For the study, published late last week in JAMA Network Open, the researchers evaluated 61 men before and after infection with the SARS-CoV-2 Omicron variant in January 2023. The men had been part of a larger cohort who had undergone magnetic resonance imaging (MRI) and neuropsychiatric screenings before infection in August and September 2022. Average age was 43 years.

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.

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.
