Evaluation of Statistical Approaches in Developing a Predictive Model of Severe COVID-19 during Early Phase of Pandemic with Limited Data Resources.
As evidence of risk factors for severe cases of coronavirus disease 2019 (COVID-19) was uncertain in early phases of the pandemic, the development of an efficient predictive model for severe cases to triage high-risk individuals represented an urgent yet challenging issue. It is crucial to select appropriate statistical models when available data and evidence are limited. This study was conducted to assess the accuracy of different statistical models in predicting severe cases using demographic data from patients with COVID-19 prior to the emergence of consequential variants. ⋯ The benefit of performing feature selection with a training dataset before building models was seen in some models, but not in all models. In summary, the naïve Bayes and RF models exhibited ideal predictive performance even with limited available data. The benefit of performing feature selection before building models with limited data resources depended on machine learning methods and parameters.

Hospitalizations of sarcoidosis patients before and during the COVID-19 pandemic in Poland.
Sarcoidosis is a multisystemic granulomatous disease that mostly affects the lungs and lymphatic system. Due to its rarity and variable clinical course, analyses of factors related to sarcoidosis should be based on large databases and long observation periods. ⋯ Health care changes related to the outbreak of the COVID‑19 pandemic may have increased the health debt for inpatient sarcoidosis treatment. The occurrence of sarcoidosis in Poland may be related to demographic and territorial factors.

This study estimated the direct medical and indirect costs associated with coronavirus disease 2019 (COVID-19) diagnoses among U.S. active duty (AD) Army service members (SMs). These cost estimates provide the U.S. Military with a better understanding of the financial burden of COVID-19 and provide a foundation for cost-effectiveness estimates. ⋯ The direct medical costs of a COVID-19 encounter in the MHS ($606) are a small portion of the costs for a SM with COVID-19. Indirect costs of lost and limited duty associated with COVID-19 averaged seven times higher ($4,331) and accounted for the vast majority of costs. Recognition of these costs is important especially given that soldiers in the hospital or in quarters being quarantined are complete losses of manpower to the Army. While the COVID-19 pandemic is ongoing and prevention, treatment, and mitigation efforts continue to evolve, having reliable estimates of direct medical and indirect costs from this study allows the U.S. Army and MHS to better account for the cost of this pandemic for its population.

Taiwan has a substantial number of veterans, but knowledge regarding their emergency department (ED) visits during the coronavirus disease 2019 (COVID-19) pandemic remains limited. This study examined the characteristics of veterans' ED visits during Taiwan's COVID-19 epidemic. ⋯ The distinctions in ED visits highlighted the individuality of veterans' medical needs. Our findings suggest that the veteran medical system can add to the focus on improving senior-friendly care, fall prevention, quality of life of institutionalized veterans, access for homeless veterans, and care for ambulatory care-sensitive conditions.
