Pulmonary Dysfunction after Pediatric COVID-19
Radiology – Long COVID occurs in lower frequency in children and adolescents than in adults. Morphologic and free-breathing phase-resolved functional low-field MRI may identify persistent pulmonary manifestations after SARS-CoV-2 infection.

Some kids, teens have long-term lung damage after COVID-19
CIDRAP – Magnetic resonance imaging (MRI) reveals lung damage in nonhospitalized children and teens who either had COVID-19 up to a year earlier or have long-COVID symptoms, according to a single-center clinical trial published this week in Radiology. Researchers in Germany evaluated changes in lung structure and function in 54 pediatric COVID-19 survivors and nine healthy controls aged […]

Circulating anti-nuclear autoantibodies in COVID-19 survivors predict long-COVID symptoms
European Respiratory Journal – Autoimmunity has been reported in patients with severe COVID-19. We investigated whether antinuclear/extractable-nuclear antibodies (ANAs) were present up to a year after infection, and if they were associated with the development of clinically relevant Post-Acute Sequalae of COVID-19 (PASC) symptoms.

Signs of autoimmune disease, difficulty exercising noted 1 year after COVID
CIDRAP – Two studies published today in the European Respiratory Journal describe long-COVID findings, one revealing signs of autoimmune disease in 41% of blood samples taken 1 year after recovery, and the other showing that 23% of patients still had exercise intolerance a year after hospital release.

An ACE2-dependent Sarbecovirus in Russian bats is resistant to SARS-CoV-2 vaccines
PLoS Pathogens – Spillover of sarbecoviruses from animals to humans has resulted in outbreaks of severe acute respiratory syndrome SARS-CoVs and the ongoing COVID-19 pandemic. Efforts to identify the origins of SARS-CoV-1 and -2 has resulted in the discovery of numerous animal sarbecoviruses–the majority of which are only distantly related to known human pathogens and […]

COVID-19 Infections Increase Risk of Long-Term Brain Problems: Strokes, Depression, Anxiety, Migraines
SciTech Daily – If you’ve had COVID-19, it may still be messing with your brain. According to new research, those who have been infected with the SARS-CoV-2 virus are at increased risk of developing a range of neurological conditions in the first year after the infection. A comprehensive analysis of federal health data reveals that such complications include […]

SARS-CoV-2 Main Protease Suppresses Innate Immunity By Cleaving Proteins Required For Interferon Induction And Inflammation
Forbes – Many viruses rely on proteases to process polypeptides into smaller proteins required for replication and virus production. SARS-CoV-2 is no exception. It contains two proteases in the long open reading frame of ORF1A1B that encode for 15 proteins which need proteolytic processing. Main protease, or Mpro, is the cysteine protease responsible for most […]

Household transmission of the SARS-CoV-2 Omicron variant in Denmark
Nature – In late 2021, the Omicron SARS-CoV-2 variant overtook the previously dominant Delta variant, but the extent to which this transition was driven by immune evasion or a change in the inherent transmissibility is currently unclear. We estimate SARS-CoV-2 transmission within Danish households during December 2021. Among 26,675 households (8,568 with the Omicron VOC), […]
