Case ReportsSevere acute respiratory distress syndrome in coronavirus disease 2019-infected pregnancy: obstetric and intensive care considerations.
Since the emergence of a novel coronavirus (severe acute respiratory syndrome coronavirus 2) in Wuhan, China, at the end of December 2019, coronavirus disease 2019 has been associated with severe morbidity and mortality and has left world governments, healthcare systems, and providers caring for vulnerable populations, such as pregnant women, wrestling with the optimal management strategy. Unique physiologic and ethical considerations negate a one-size-fits-all approach when caring for critically ill pregnant women with coronavirus disease 2019, and few resources exist to guide the multidisciplinary team through decisions regarding optimal maternal-fetal surveillance, intensive care procedures, and delivery timing. We present a case of rapid clinical decompensation and development of severe acute respiratory distress syndrome in a woman at 31 weeks' gestation to highlight these unique considerations and present an algorithmic approach to the diagnosis and management of the disease.

Case ReportsFalse-negative testing for severe acute respiratory syndrome coronavirus 2: consideration in obstetrical care.
Because the obstetrical population seems to have a high proportion of asymptomatic patients who are carriers of severe acute respiratory syndrome coronavirus 2, universal testing has been proposed as a strategy to risk-stratify all obstetrical admissions and guide infection prevention protocols. Here, we describe a case of a critically ill obstetrical patient with all the clinical symptoms of coronavirus disease 2019 and 3 false-negative results of nasopharyngeal swabs for molecular testing. We review and discuss the uncertain clinical characteristics of current severe acute respiratory syndrome coronavirus 2 molecular testing and the implications of false-negative results in the obstetrical population.

CommentD-dimer is associated with the risk of mortality in Coronavirus Disease 2019 patients.
This study aims to investigate the association between D-dimer and the risk of mortality in coronavirus disease 2019 (COVID-19) patients using a meta-analysis. We found that the D-dimer levels in non-survival patients were significantly higher than those in survival patients (SMD = 0.91, 95% CI = 0.79 to 1.03). In conclusion, the elevated D-dimer levels were associated with an increased risk of mortality in COVID-19 patients.

Severe acute respiratory syndrome coronavirus 2 viral load in the upper respiratory tract peaks around symptom onset and infectious virus persists for 10 days in mild-to-moderate coronavirus disease (n = 324 samples analysed). RT-PCR cycle threshold (Ct) values correlate strongly with cultivable virus. Probability of culturing virus declines to 8% in samples with Ct > 35 and to 6% 10 days after onset; it is similar in asymptomatic and symptomatic persons. Asymptomatic persons represent a source of transmissible virus.

Sheba Medical Center, Tel Hashomer, is a tertiary hospital located in the center of Israel. It is the largest hospital in Israel and was the first to face coronavirus disease-2019 (COVID-19) patients in the country at the beginning of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic. ⋯ Our triage method was successful in separating COVID-19 positive from negative patients and maintained the regular hospital clean of COVID-19 allowing treatment continuation of regular non-COVID-19 patients.
