The reasons for observed sex differences are less understood in PCS compared to acute Covid-19 infections. Fatigue is a central symptom of affective disorders such as depression as well as syndromes associated with exposure to viral infections known prior to Covid-19 such as myalgic-encephalomyeliti...
We defined the exposure of interest as a binary, time-invariant variable based on SSRI use during COVID-19. It remains possible that factors related to the duration of SSRI use, timing of SSRI use, or SSRI dosage may modify this relationship, although these factors are poorly documented (i...
Variation in false-negative rate of reverse transcriptase polymerase chain reaction–based SARS-CoV-2 tests by time since exposure. Ann. Intern. Med. 173, 262–267 (2020). Article PubMed Google Scholar Levine-Tiefenbrun, M. et al. SARS-CoV-2 RT-qPCR test detection rates are associated ...
Because reports of chilblains linked to COVID-19 suggest that exposure to COVID-19 infection preceded chilblains diagnosis by up to 30 days,2,11 we compared the number of cases of COVID-19 in a particular month and chilblains the following month for 23 geographic locations. Our analysis...
The Cerner Real World Data COVID-19 database represents patients with a diagnosis of COVID-19 or COVID-19 exposure who had an emergency department or urgent care visit or were admitted for observation or hospitalized. Encounters include laboratory and pharmacy information (eg, medication orders, ...
In addition, COVID-19 vaccination was employed as a time-varying covariate to eliminate any contribution of vaccine exposure to the potential risk of thrombosis, pericarditis, or myocarditis [15]. Subgroup analyses for the primary and secondary outcomes were conducted according to age (stratified by...
In order to analyze the specific impact of COVID-19 on each cancer type, two periods were determined: the COVID-19-free period (January 2019 to February 2020) and the COVID-19 exposure period (March to December 2020). The probability (OR and 95% confidence interval (CI)) of observing...
There may be several reasons for the decrease in ED visits for pediatric patients, such as fear of exposure and risk of infection, a decrease in the prevalence of infectious disease itself due to infection prevention behavior, and a decrease in access to EDs due to each hospital’s infectious...

Some authors hypothesized that the limited exposure to microorganisms during the first pandemic year led to a higher number of severe cases than suggested by historical data [8]. However, other factors that emerged during the pandemic have also been claimed to favor this shift. First, a drastic...
