La Covid-19, due au virus Sars-CoV-2, semble prédisposer les patients aux phénomènes thrombotiques (artériels et veineux). Ces atteintes apparaissent liées à l'inflammation excessive ainsi qu'à une dysfonction plaquettaire et endothéliale. [ABSTRACT FROM AUTHOR]

(1) Introduction: The neutrophil-to lymphocyte ratio is valued as a predictive marker in several inflammatory diseases. For example, an increasing NLR is a risk factor of mortality in sepsis. It also appears to be helpful in other settings such as cancer. The aim of our work was to study the prognostic value of NLR for disease severity and mortality in patients infected with SARS-CoV-2 upon their admission to the Emergency Department (ED) and its early variation (ΔNLR) in the first 24 h of management (H-24). (2) Methods: Between 1 March and 30 April 2020, we conducted a multicenter and retrospective cohort study of patients with moderate or severe coronavirus disease 19 (COVID-19), who were all hospitalized after presenting to the ED. (3) Results: A total of 1035 patients were included in our study. Factors associated with infection severity were C-reactive protein level (OR: 1.007, CI 95%: [1.005–1.010], p < 0.001), NLR at H-24 (OR: 1.117, CI 95%: [1.060–1.176], p < 0.001), and ΔNLR (OR: 1.877, CI 95%: [1.160–3.036], p: 0.01). The best threshold of ΔNLR to predict the severity of infection was 0.222 (sensitivity 56.1%, specificity 68.3%). In multivariate analysis, the only biochemical factor significantly associated with mortality was again ΔNLR (OR: 2.142, CI 95%: ([1.132–4.056], p: 0.019). The best threshold of ΔNLR to predict mortality was 0.411 (sensitivity 53.3%; specificity 67.3%). (4) Conclusion: The NLR and its early variation (ΔNLR) could help physicians predict both severity and mortality associated with SARS-CoV-2 infection, hence contributing to optimized patient management (accurate triage and treatment).

Background and Importance: Gender bias in healthcare can significantly influence clinical decision-making, potentially leading to disparities in treatment outcomes. This study addresses the impact of patient gender on the decision-making process for establishing a ceiling of care in emergency medicine, particularly the decision to limit tracheal intubation., Objective: To determine whether patient gender influences emergency physicians' decisions regarding the recommendation for tracheal intubation in critically ill patients., Design: A European survey-based study was conducted using a standardized clinical scenario to assess physicians' decisions in a controlled setting., Settings and Participants: The survey targeted European emergency physicians over a 2-week period in April 2024. A total of 3423 physicians participated, with a median age of 40 years and a distribution of 46% women. Physicians were presented with a clinical vignette of a 75-year-old patient in acute respiratory distress. The vignettes were randomized to vary only by the patient's gender (woman/man) and level of functional status: (1) can grocery shop alone, (2) cannot grocery shop alone but can bathe independently, or (3) cannot perform either task independently., Outcome Measures and Analysis: The primary outcome was the recommendation for intubation, with secondary analyses exploring the influence of patient functional status levels. Multivariable logistic regression was used to adjust for potential confounders, including physician gender, age, experience, and practice setting., Main Results: A total of 3423 physicians responded, mostly from France, Spain, Italy, and the UK (1,532, 494, 247, and 245 respectively). Women patients were less likely to be intubated compared to male patients [67.9% vs. 71.7%; difference 3.81%; 95% confidence interval (CI), 0.7-6.9%]. The likelihood of recommending intubation decreased with lower levels of patient functional status. Women physician gender was also associated with a reduced likelihood of recommending intubation., Conclusion: This study suggests a significant gender-based disparity in emergency care decision-making, with women patients being less likely to receive recommendations for intubation. However, these results should be interpreted with caution due to potential limitations in the representativity of respondents and the uncertain applicability of survey responses to real-life clinical practice., (Copyright © 2024 Wolters Kluwer Health, Inc.
