The Neutrophil-to-Lymphocyte Ratio Determines Clinical Efficacy of Corticosteroid Therapy in Patients with COVID-19.

TL;DR: The increased prevalence of obesity, diabetes, and cardiovascular risk factors in people hospitalized with severe COVID-19 illness has engendered considerable interest in the metabolic aspects of SARS-CoV-2-induced pathophysiology as mentioned in this paper.

TL;DR: This minireview provides an update of the main findings of NETosis and NETs in immunothrombosis and other COVID-19-related disorders, such as aberrant immunity, neurological disorders, and post CO VID-19 syndromes including lung fibrosis, neurological disorder, tumor progression, and deteriorated chronic illness.

TL;DR: In this paper, the authors summarize evidence on the value of the integrative inflammation markers neutrophil-to-lymphocyte ratio (NLR), PLR and SII for depiction of exercise-induced inflammation and highlight potential applications in exercise settings.

TL;DR: In this paper, the authors summarize the current progress in the field as well as methods and sites of islet transplantation, including stem cell-derived functional human islets, and discuss the contribution of immune cells, vessel formation, extracellular matrix, and nutritional supply on islet graft survival.

TL;DR: In patients hospitalized with Covid-19, the use of dexamethasone resulted in lower 28-day mortality among those who were receiving either invasive mechanical ventilation or oxygen alone at randomization but not among those receiving no respiratory support.

TL;DR: Investigation of NLR and lymphocyte subsets is helpful in the early screening of critical illness, diagnosis and treatment of COVID-19 and shows the novel coronavirus might mainly act on lymphocytes, especially T lymphocytes.

TL;DR: An important approach to evaluating evidence for causation in the face of unmeasured confounding is sensitivity analysis (or bias analysis), and it is proposed that observational studies start reporting the E-value, a new measure related to evidence for causality.

TL;DR: A prospective meta-analysis that pooled data from 7 randomized clinical trials that evaluated the efficacy of corticosteroids in 1703 critically ill patients with COVID-19 found that low-dose dexamethasone reduced mortality in hospitalized patients with Cohen's disease who required respiratory support.
