In-Hospital Mortality and Prediction in an Urban U.S. Population With COVID-19.

Coronavirus disease 2019 (COVID-19) has touched every aspect of society, and as the pandemic continues around the globe, many of the clinical factors that influence the disease course remain unclear. A useful clinical decision-making tool is a risk stratification model to determine in-hospital mortality as defined in this study. The study was performed at Robert Wood Johnson University Hospital (RWJUH) in New Brunswick, New Jersey, USA. Data was extracted from our electronic medical records on 44 variables that included demographic, clinical, laboratory tests, treatments, and mortality information. We used the least absolute shrinkage and selection operator regression with corrected Akaike's information criterion to identify a subset of variables that yielded the smallest estimated prediction error for the risk of in-hospital mortality. During the study period, 808 COVID-19 patients were admitted to RWJUH. The sample size was limited to patients with at least one confirmed in-house positive nasopharyngeal swab COVID-19 test. Pregnant patients or those who were transferred to our facility were excluded. Patients who were in observation and were discharged from the emergency room were also excluded. A total of 403 patients had complete values for all variables and were eligible for the study. We identified significant clinical, laboratory, and radiologic variables determining severe outcomes and mortality. An in-hospital mortality risk calculator was created after the identification of significant factors for the specific cohort, which were abnormal CT scan or chest X-ray, chronic kidney disease, age, white blood cell count, platelet count, alanine aminotransferase, and aspartate transaminase with a sensitivity, specificity, and negative predictive value of 82%, 72%, and 93%, respectively. While numerous reports from around the globe have helped outline the pandemic, demographic factors vary widely. This study is more applicable to an urban, highly diverse population in the United States.

Gastrointestinal Findings in a Patient With COVID-19.

The novel coronavirus (severe acute respiratory syndrome coronavirus 2) that causes coronavirus disease 2019 was discovered in December 2019 in Wuhan, China, and has rapidly spread across the world becoming a pandemic and disrupting societies, economies, and public health. Digestive symptoms and gastrointestinal (GI) manifestations are increasingly being reported in patients with the virus. There is also a growing body of evidence to suggest that liver injury is frequent. We present a patient diagnosed with coronavirus who presented with several days of GI symptoms and discuss the relevance of GI disease and liver injury in these patients.
