Arthralgia among Patients with COVID-19 Infection Admitted to the Department of Medicine of a Tertiary Care centre: A Descriptive Cross-sectional Study.
COVID-19 is a global pandemic that has affected millions of people worldwide. It predominantly affects the respiratory tract causing various respiratory symptoms. It also causes various musculoskeletal symptoms in the form of arthralgia and myalgia which may be incapacitating for some patients. The objective of this study was to find out the prevalence of arthralgia among patients with COVID-19 infection admitted to the Department of Medicine. ⋯ arthralgia; COVID-19; prevalence; tertiary care.

Changing face of non-infectious pediatric uveitis in the pre-pandemic and pandemic periods: a comparison study.
Our aim in this study was to reveal the clinical features of pediatric uveitis in the pandemic period and to compare it with the pre-pandemic era. ⋯ The present study involved a large number of pediatric patients with uveitis. There are some differences in the characteristics of pediatric uveitis cases comparing the pandemic period and the pre-pandemic period. This increased frequency and changing clinical features of pediatric uveitis seems to be a result of COVID-19 infection.

We present the case of a young woman admitted for diabetic ketoacidosis with persistent, asymptomatic lactic acid (LA) elevation during the evolving COVID-19 pandemic. Cognitive biases in interpreting an elevated LA in this patient's care resulted in an extensive infectious workup instead of the low-cost and potentially diagnostic provision of empiric thiamine. We discuss clinical patterns and etiologies of LA elevation and the role of thiamine deficiency. We also address cognitive biases potentially affecting the interpretation of elevated lactate levels and provide guidance for clinicians to determine appropriate patients for empiric thiamine administration.

Strict visitor restrictions during the COVID-19 pandemic have been associated with staff moral distress in numerous clinical settings, yet little is known about effects on perceptions of pediatric end-of-life care. ⋯ The findings support affording some flexibility to visitation at end of life, which may mitigate negative staff perceptions of quality of dying and death. With the profound effects of COVID-19 on end-of-life care provision, these results may have implications for future global challenges.

Observational Study
Challenges in Estimating the Effectiveness of COVID-19 Vaccination Using Observational Data.
The COVID-19 vaccines were developed and rigorously evaluated in randomized trials during 2020. However, important questions, such as the magnitude and duration of protection, their effectiveness against new virus variants, and the effectiveness of booster vaccination, could not be answered by randomized trials and have therefore been addressed in observational studies. Analyses of observational data can be biased because of confounding and because of inadequate design that does not consider the evolution of the pandemic over time and the rapid uptake of vaccination. ⋯ The nature of the confounding depends on the analysis strategy: Estimating "per-protocol" effects (accounting for vaccination of initially unvaccinated persons after baseline) may require adjustment for both baseline and "time-varying" confounders. These issues are illustrated by using observational data from 2 780 931 persons in the United Kingdom aged 70 years or older to estimate the effect of a first dose of a COVID-19 vaccine. Addressing the issues discussed in this article should help authors of observational studies provide robust evidence to guide clinical and policy decisions.
