Serum Hydrogen Sulfide and Outcome Association in Pneumonia by the SARS-CoV-2 Coronavirusxs.
The pneumonia of COVID-19 illness has often a subtle initial presentation making mandatory the use of biomarkers for evaluation of severity and prediction of final patient disposition. We evaluated the use of hydrogen sulfide (H2S) for the outcome of COVID-19 pneumonia. ⋯ It is concluded that H2S is a potential marker for severity and final outcome of pneumonia by the SARS-CoV-2 coronavirus. Its correlation with IL-6 suggests anti-inflammatory properties.

Identifying Septic Shock Populations Benefitting from Polymyxin B Hemoperfusion: A Prospective Cohort Study Incorporating a Restricted Cubic Spline Regression Model.
Polymyxin B hemoperfusion (PMX-HP) is an adjuvant therapy for sepsis or septic shock that removes circulating endotoxin. However, PMX-HP has seldom achieved expectations in randomized trials targeting nonspecific overall sepsis patients. If used in an optimal population, PMX-HP may be beneficial. This study aimed to identify the optimal population for PMX-HP in patients with septic shock. ⋯ Our results suggested that although PMX-HP did not reduce in-hospital mortality among overall septic shock patients, it may benefit a limited population with high age and higher disease severity.

Due to the rapidly escalating number of cases and the low baseline of overall health in Louisiana, we sought to determine the prognostic value of the neutrophil-to-lymphocyte ratio (NLR) in hospitalized COVID patients in two major metropolitan areas with the highest prevalence of cases and exceedingly high rates of obesity and other comorbid conditions. We hypothesized that elevated NLR would be a prognostic indicator of mortality. ⋯ NLR is a prognostic factor for endotracheal intubation upon hospital admission and independent predictor for risk of mortality in SARS-CoV-2 patients on subsequent hospital days. Clinical research efforts should examine effects of strategies such as arginase inhibition alone and/or inhaled nitric oxide to ameliorate the effects of elevated NLR.

Randomized Controlled Trial Multicenter Study
Pentraxin-3, troponin T, N-terminal pro-B-type Natriuretic Peptide in septic patients.
To investigate the behavior of pentraxin-3 (PTX3), troponin T (hsTnT), N-terminal pro-B type Natriuretic Peptide (NT-proBNP) in sepsis and their relationships with sepsis severity and oxygen transport/utilization impairment. ⋯ The selected biomarkers seem related to different mechanisms during sepsis: PTX3 to sepsis severity, hsTnT to impaired oxygen transport, NT-proBNP to sepsis severity, oxygen transport, and aggressive fluid strategy.

Clinical Course of 195 Critically ILL COVID-19 Patients, A Retrospective Multi-Center Study.
Coronavirus disease-2019 (COVID-19) outbreak has spread around the world. However, the dynamic course of critically ill COVID-19 has not been described thoroughly. ⋯ ARDS and shock were notable in the critical illness of COVID-19. Ventilation support and hemodynamic support were the cornerstones for critical care. High viral load was associated with death of critically ill COVID-19 patients.
