The COVID-19 pandemic presented several challenges, leaving the specific impact of class closures on student performance unclear. To address this, researchers examined the effect of pre-pandemic class closures due to influenza outbreaks on students’ test scores in Japan. They found that class closures adversely affected the math scores of elementary school boys from low-income households, likely due to lost instructional time and unhealthy behaviors. Fortunately, high-quality teachers could help students recover from the learning loss.
Pediatric data show that the increase in long COVID risk was also accompanied by the increased chance of developing a number of other related conditions
Long COVID is a chronic condition that causes cognitive problems known as “brain fog,” but its biological mechanisms remain largely unclear. Now, researchers from Japan used a novel imaging technique to visualize AMPA receptors—key molecules for memory and learning—in the living brain. They discovered that higher AMPA receptor density in patients with Long COVID was closely tied to the severity of their symptoms, highlighting these molecules as potential diagnostic biomarkers and therapeutic targets.
Children and adolescents were twice as likely to experience long COVID after catching COVID for the second time, compared to their peers with a single previous infection, according to a large study funded by the National Institutes of Health (NIH) and published in Lancet Infectious Diseases. These results run counter to the popular perceptions that COVID in children is "mild" and that reinfections with COVID do not carry the same risk of long COVID that initial infections do.
Why this matters:
Emergency departments, or EDs, are becoming an initial contact for patients to get hospice and palliative care referrals and consultations when presenting to the hospital for care.
In the five years since COVID-19, hospice and palliative care consultations in hospital emergency departments have increased over 170%, although this trend has been growing since 2000.
Increasing access to hospice and palliative care from the ED can enhance quality of life for both patients and their families.
People who suspect that their sense of smell has been dulled after a bout of COVID-19 are likely correct, a new study using an objective, 40-odor test shows. Even those who do not notice any olfactory issues may be impaired.
