Lots of areas of the brain (prefrontal cortex, anterior cingulate cortex, insula, amygdala, motor cortex, and more) have been implicated in chronic fatigue syndrome (ME/CFS), but somehow it fits that the most difficult-to-reach and hard-to-study part of the brain – the brainstem – might just be the cat’s meow. As […]

Only 41 (6.3%) out of 645 patients with #LongCovid recovered after 2 years. High quality study, because these patients were interviewed by a physician. pic.twitter.com/5WBuvOiyc4— Sue (@inkblue01) January 8, 2024

Analysis of blood revealed that Long COVID is characterized by changes to complement proteins and platelet activation.

Timely, accurate, and comprehensive estimates of SARS-CoV-2 daily infection rates, cumulative infections, the proportion of the population that has been infected at least once, and the effective reproductive number (Reffective) are essential for understanding the determinants of past infection, current transmission patterns, and a population’s susceptibility to future infection with the same variant. Although several studies have estimated cumulative SARS-CoV-2 infections in select locations at specific points in time, all of these analyses have relied on biased data inputs that were not adequately corrected for. In this study, we aimed to provide a novel approach to estimating past SARS-CoV-2 daily infections, cumulative infections, and the proportion of the population infected, for 190 countries and territories from the start of the pandemic to Nov 14, 2021. This approach combines data from reported cases, reported deaths, excess deaths attributable to COVID-19, hospitalisations, and seroprevalence surveys to produce more robust estimates that minimise constituent biases

Die FPÖ und andere Rechtsparteien behaupten, dass die Welt über Nutzen und Wirkung der Covid-Impfstoffe getäuscht wurde. Die Fakten erzählen aber eine ganz andere Geschichte.

COVID-19 infection has worse outcomes in immunocompromised individuals. This includes those with diabetes mellitus, cancer, chronic autoimmune diseases requiring immunomodulatory therapy, and solid-organ transplant recipients on chronic immunosuppression. Using the National Inpatient Sample Database …

Common as they are, reinfections may have lasting impacts.

Importance SARS-CoV-2 infection can result in ongoing, relapsing, or new symptoms or organ dysfunction after the acute phase of infection, termed Post-Acute Sequelae of SARS-CoV-2 (PASC), or long COVID. The characteristics, prevalence, trajectory and mechanisms of PASC are poorly understood. The objectives of the Researching COVID to Enhance Recovery (RECOVER) tissue pathology study (RECOVER-Pathology) are to: (1) characterize prevalence and types of organ injury/disease and pathology occurring with PASC; (2) characterize the association of pathologic findings with clinical and other characteristics; (3) define the pathophysiology and mechanisms of PASC, and possible mediation via viral persistence; and (4) establish a post-mortem tissue biobank and post-mortem brain imaging biorepository. Methods RECOVER-Pathology is a cross-sectional study of decedents dying at least 15 days following initial SARS-CoV-2 infection. Eligible decedents must meet WHO criteria for suspected, probable, or confirmed infection and must be aged 18 years or more at the time of death. Enrollment occurs at 7 sites in four U.S. states and Washington, DC. Comprehensive autopsies are conducted according to a standardized protocol within 24 hours of death; tissue samples are sent to the PASC Biorepository for later analyses. Data on clinical history are collected from the medical records and/or next of kin. The primary study outcomes include an array of pathologic features organized by organ system. Causal inference methods will be employed to investigate associations between risk factors and pathologic outcomes. Discussion RECOVER-Pathology is the largest autopsy study addressing PASC among US adults. Results of this study are intended to elucidate mechanisms of organ injury and disease and enhance our understanding of the pathophysiology of PASC.

This cohort study uses data from a US national claims database to assess whether COVID-19 vaccination is associated with herpes zoster infection.

BA.2.86 is a recently emerged, highly mutated SARS-CoV-2 variant that spreads in many countries and threatens human health. This study shows that BA.2.86, unlike closely related variants, can enter lung cells with high efficiency and in a TMPRSS2-dependent fashion and is resistant against therapeutic antibodies.

SARS-CoV-2-related pangolin coronavirus GX\_P2V(short\_3UTR) can cause 100% mortality in human ACE2-transgenic mice, potentially attributable to late-stage brain infection. This underscores a spillover risk of GX_P2V into humans and provides a unique model for understanding the pathogenic mechanisms of SARS-CoV-2-related viruses. ### Competing Interest Statement The authors have declared no competing interest.
