Article Abstract
Genes involved in the regulation of viral recognition and its entry into a host cell have been identified as candidates for genetic association studies on COVID-19 severity. Published findings on the effects of polymorphisms within , , , and genes remained inconclusive, so we conducted a systematic review and meta-analysis in order to elucidate their potential involvement in the genetic basis underlying the severity of COVID-19 and/or an outcome of SARS-CoV-2 infection. Identification of potentially eligible studies was based on PubMed, Scopus and Web of Science database search. Relevant studies (n=29) with a total number of 8247 SARS-CoV-2-positive participants were included in qualitative synthesis, while results of 21 studies involving 5939 were pooled in meta-analysis. Minor allele I of rs1799752 located within was identified as a protective variant against severe COVID-19, while its effect on mortality rate was opposite. Similarly, minor allele A of polymorphism, rs2285666, was found to associate with a decreased risk of severe COVID-19 ( = 0.003, OR = 0.512, 95 % CI = 0.331-0.793). Statistical significance was also seen for the association between COVID-19 severity and rs12329760 located within . Our results did not support the supposed association of rs12252 in and polymorphisms within with disease severity. We conclude that genetic variants within , and may be potential biomarkers of COVID-19 severity, which needs to be further confirmed in a larger set of studies.

The Permanente Medical Group, Pleasanton, California, United States of America.
Background: Research on Post-acute sequelae of COVID (PASC) has focused on the prevalence of symptoms, leaving gaps in our understanding of predictors of health care seeking.
Objective: To identify clinical and sociodemographic characteristics associated with PASC care seeking.
Methods: Retrospective cohort study of adult patients with COVID-19 diagnosis between January 1, 2021 and June 30, 2022 in a community-based comprehensive health care delivery system at 21 hospitals and medical clinics in Northern California.
Factors associated with prolonged hospitalizations for COVID-19 during the first three waves of the pandemic: Evidence from a Southeastern State of Brazil.

A comprehensive understanding of the factors influencing the epidemiological dynamics of COVID-19 across the pandemic waves-particularly in terms of disease severity and mortality-is critical for optimizing healthcare services and prioritizing high-risk populations. Here we aim to analyze the factors associated with short-term and prolonged hospitalization for COVID-19 during the first three pandemic waves. We conducted a retrospective observational study using data from individuals reported in the e-SUS-VS system who were hospitalized for COVID-19 in a state in a southeast state of Brazil.

Background: Obesity was a risk factor for severe COVID-19 in children during early outbreaks of ancestral SARS-CoV-2 and the Delta variant. However, the relationship between obesity and COVID-19 severity during the Omicron wave remains unclear.
Methods: This multicenter, observational study included polymerase chain r eaction-confirmed SARS-CoV-2-infected children and adolescents from Australia, Brazil, Italy, Portugal, Switzerland, Thailand, the United Kingdom and the United States hospitalized between January 1, 2020, and March 31, 2022.

From the Department of Pediatric Intensive Care Unit, The Affiliated Hospital of Qingdao University, Qingdao, Shandong, China.
Background: Antiviral drugs and coronavirus disease 2019 (COVID-19) vaccines have significantly reduced COVID-19-related hospitalizations and deaths in infected children. However, COVID-19 continues to pose a major mortality risk in young children. High-sensitive cardiac troponin (Hs-cTn) is a specific marker of myocardial cell damage.
