Neurological post-COVID syndrome is associated with substantial impairment of verbal short-term and working memory.

A substantial proportion of patients suffer from Post-COVID Syndrome (PCS) with fatigue and impairment of memory and concentration being the most important symptoms. We here set out to perform in-depth neuropsychological assessment of PCS patients referred to the Neurologic PCS clinic compared to patients without sequelae after COVID-19 (non-PCS) and healthy controls (HC) to decipher the most prevalent cognitive deficits. We included n = 60 PCS patients with neurologic symptoms, n = 15 non-PCS patients and n = 15 healthy controls.

Viral infections of the central nervous system (CNS) have been emerging and re-emerging worldwide, and the Australasia region has not been spared. Enterovirus A71 and enterovirus D68, both human enteroviruses, are likely to replace the soon-to-be eradicated poliovirus to cause global outbreaks associated with neurological disease. Although prevalent elsewhere, the newly emergent orthoflavivirus, Japanese encephalitis virus (genotype IV), caused human infections in Australia in 2021, and almost certainly will continue to do so because of spillovers from the natural animal host-vector life cycle endemic in the country.

Article Synopsis
- COVID-19, caused by SARS-CoV-2, poses serious global health risks, including the potential for secondary liver injury related to metabolic enzyme changes.
- This study explores how prior infection with SARS-CoV-2 affects alcohol-induced liver damage, using transgenic mice that express human ACE2.
- Results showed that infected mice experienced worsened liver injury after alcohol consumption, with alterations in metabolic enzymes and increased levels of a toxic alcohol byproduct, indicating a complex interaction between COVID-19 and alcohol effects on the liver.

Article Synopsis
- The study investigates the neurobiological factors that make individuals susceptible to fatigue after a mild COVID-19 infection, aiming to understand the link between brain structure and post-COVID neuropsychiatric symptoms.
- Researchers used neuropsychiatric assessments and MRI scans on individuals who had COVID-19 and a control group to analyze brain regions related to fatigue.
- Results indicate that specific brain areas, particularly the right dorsolateral prefrontal cortex, are linked to fatigue severity and can predict ongoing fatigue symptoms months after the infection, shedding light on the neural underpinnings of post-COVID conditions.

Objectives: We investigated the effect modification of health literacy (HL) in ameliorating the negative impact of underlying health conditions (UHC) on long COVID among non-hospitalized and hospitalized survivors.
Study Design: An online cross-sectional study was conducted in Vietnam from December 2021 to October 2022.
Methods: A sample of 4507 participants recruited from 18 hospitals and health centers were those aged 18 or older, had contracted COVID-19 for at least 28 days, and were not in the acute phase of reinfection.
