Introduction: A cluster of atypical pneumonia cases in Wuhan, China, turned out to be a highly contagious disease, swept across most of the countries, and soon after was announced as a pandemic. Therefore we aimed to investigate the demographics and factors associated with the disease outcome.
Methods: In this retrospective chart review, we screened patients admitted to the emergency department with severe acute respiratory infection due to coronavirus disease 2019 (COVID-19) between March 15, 2020 and April 30, 2020. Age, gender, symptoms, laboratory data, and radiology data were obtained, as well as outcomes and length of stay.
Results: We identified 177 patients (54.8% male). Seventy-eight percent of the cases were admitted into wards whereas 22% of the cases were admitted into the intensive care unit (ICU). Twenty-five percent of the cases needed invasive mechanical ventilation during their hospital stay and median length of hospital stay until death or discharge was eight days (interquartile range (IQR) 5.0 - 16.0). Among 177 patients, overall in-hospital mortality rate was 19.8% (n=35; male:female=18:17; p=0.6553). In-hospital mortality rates were statistically significantly higher in patients with higher age (64 vs. 74; p=0.0091), respiratory rate (RR) (28 vs. 36; p=0.0002), C-reactive protein (CRP) (54.7 vs. 104.0; p<0.0001), d-dimer (1.2 vs. 3.2; p<0.0001), ferritin (170 vs. 450.4; p<0.0001), fibrinogen (512 vs. 598; p=0.0349), international normalized ratio (INR) (1.1 vs. 1.3; p=0.0001), prothrombin time (PT) (14.8 vs. 17.4; p=0.0001), procalcitonin (0.1 vs. 0.3; p<0.0001), creatinine (0.9 vs. 1.1; p=0.0084), longer length of stay (LOS) (8.0 vs. 13.0; p=0.0251) with lower oxygen saturation (sO) (93.0% vs 87.5%; p<0.0001), diastolic blood pressure (DBP) (78 vs. 70; p=0.0039), lymphocyte (1.2 vs. 0.8; p=0.0136), and with positive polymerase chain reaction (PCR) results (28.6% vs. 12.8%; p=0.0118).
Conclusion: Patients with older age, higher RR, lower sO and DBP, higher creatinine, d-dimer, INR, CRP, procalcitonin, ferritin, and fibrinogen on initial admission were found to be less likely to survive COVID-19.

Care pathway for patients hospitalized with venous thromboembolism.
Eur J Clin Invest

URC PNVS, CIC-EC 1425, INSERM, Bichat - Claude Bernard Hospital, Assistance Publique-Hôpitaux de Paris, Paris, France.
Background: Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), is a potentially fatal disease with a multifactorial nature, impacting different medical and surgical specialties. Recently, new guidelines and direct oral anticoagulants facilitated early discharge for most DVT patients and non-severe PE patients.
Objective: The aim of this study is to illustrate the distribution of VTE patients throughout the hospital and map their care pathway from Emergency Department (ED) to hospital discharge.

Background: Whereas the increasing burden of acute myocardial infarction (MI) has been reported in sub-Saharan Africa, little is known about short- and long-term prognosis following acute MI.
Objectives: The purpose of this study was to assess in-hospital, 30-day, and 1-year all-cause mortality and adverse outcomes in patients with MI hospitalized at a cardiac center in Côte d'Ivoire.
Methods: This prospective cohort study used data from the REgistre des syndromes coronariens Aigus de CôTe d'IVoire (REACTIV).

This case involves a 21-year-old male healthcare student with a medical history of HIV-1 infection for two years and anxiety disorder. He presented to the emergency department with hemoptysis and dyspnea of sudden onset. A thoracic CT scan revealed multiple bilateral nodular ground-glass opacities suggestive of diffuse alveolar hemorrhage (DAH).

Introduction: Alcohol withdrawal syndrome (AWS) is a common condition prompting emergency department (ED) presentation. However, there are limited recent, large-scale, robust data available on the incidence, admission, and medical treatment of AWS in the ED.
Methods: This was a retrospective cohort study of ED presentations for AWS from January 1, 2016, to December 31, 2023, using Epic Cosmos.

Objectives: Identifying patients in the emergency department (ED) at higher risk for in-hospital mortality can inform shared decision making and goals-of-care discussions. Electronic health record systems allow for integrated multivariable logistic regression (LR) modeling, which can provide early predictions of mortality risk in time for crucial decision making during a patient's initial care. Many commonly used LR models require blood gas analysis values, which are not frequently obtained in the ED.
