Respiratory Support in Severely or Critically Ill ICU Patients With COVID-19 in Wuhan, China.
This case series aimed to describe the clinical characteristics of severely or critically ill patients with COVID-19 and compare the clinical characteristics of patients who received invasive respiratory support with those of patients who received noninvasive respiratory support. We included all confirmed severe or critical illness cases of COVID-19 admitted to the Intensive Care Unit (ICU) of Zhongnan Hospital of Wuhan University, a COVID-19-designated hospital, from January 8 to March 12, 2020. Cases were analyzed for epidemiological, demographic, clinical, APACHE II, SOFA, radiological features and laboratory data. ⋯ Moreover, 28 patients received invasive respiratory support and 14 (50.0%) patients died. In this single-center study, 55 severely or critically ill ICU patients were confirmed to have COVID-19 in Wuhan and the overall mortality was 29.1%. Totally 28 (50.9%) of severely or critically ill ICU patients received invasive respiratory support and 14 (50.0%) died during the follow-up period.

Various studies are underway to identify protective variables for the COVID-19 pandemic. We hypothesized that if indeed the vitamin D levels would be protective in the European population, as recently proposed, the correlation would become more robust when the countries had passed the infection peak as on May 12 2020, compared to April 8 2020, when the majority had not. Comparative analysis of data from the mentioned stages indicated a significant increase in negative correlation of vitamin D levels with COVID-19 cases per million population in later stage (r(20): -0.5504; R2 = 0.3029; p value: 0.0119 vs r(20): -0.4435; R2 = 0.1967; p value: 0.0501), whereas the correlation with deaths per million population became insignificant (r(20): -0.3935; R2 = 0.1549; p value: 0.0860 vs r(20): -0.4378; R2 = 0.1917; p value: 0.0535). Considering divergence of vitamin D levels from the mean in subgroups, e.g. children, women, aged, dedicated exploratory studies with carefully chosen matched target groups is advisable.

To evaluate the in vitro inactivation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with hydrogen peroxide (H2 O2 ) and povidone-iodine (PVP-I) oral antiseptic rinses at clinically recommended concentrations and contact times. ⋯ SARS-CoV-2 virus was completely inactivated by PVP-I oral antiseptic rinse in vitro, at the lowest concentration of 0.5 % and at the lowest contact time of 15 seconds. Hydrogen peroxide at the recommended oral rinse concentrations of 1.5% and 3.0% was minimally effective as a viricidal agent after contact times as long as 30 seconds. Therefore, preprocedural rinsing with diluted PVP-I in the range of 0.5% to 1.5% may be preferred over hydrogen peroxide during the COVID-19 pandemic.
