Intussusceptive angiogenesis could be the main driver for a specific cardiac injury induced by SARS-CoV-2
The most remarkable finding in the cardiac remodeling triggered by the SARS-CoV-2 infection was a marked neovascularization in the form of intussusceptive angiogenesis, which was associated with a significant infiltration of CD11b+/TIE2+ macrophages, which are drivers of intussusceptive angiogenesis.

According to a nationwide Swedish study, the use of antidepressants is associated with faster cognitive deterioration in patients with dementia
This nationwide cohort study showed that the current use of antidepressants, in particular SSRIs (i.e., citalopram, sertraline, and escitalopram) and mirtazapine was associated with faster cognitive decline in patients with dementia.

CDC reports high severity season of influenza for all age groups
Based on data available for the week ending February 8, 2025, this season is classified as a high severity season for all age groups (children, adults, older adults) for the first time since 2017-2018.
Chorea after COVID-19 infection or vaccination
In these two systematic reviews, the authors examined the existing literature on chorea associated with COVID-19 infection or vaccination.
A Korean nationwide study conducted on more than 44 million vaccinated individuals found that the incidence of myocarditis associated with COVID vaccination was highest in males aged 12 to 17 years, and the most serious adverse effect was sudden cardiac death
The authors concluded that the findings of sudden cardiac deaths attributable to COVID vaccine-related myocarditis warrant the careful monitoring or warning of sudden cardiac death as a potentially fatal complication of COVID-19 vaccination, especially in individuals younger than 45 years of age who received the mRNA vaccines.
New-onset or relapse of uveitis within a month after COVID-19 infection or vaccination
These studies found an association between COVID-19 infection or vaccination and newly diagnosed or recurrent uveitis.
