There are only a few models developed for risk-stratifying COVID-19 patients with suspected pneumonia in the emergency department (ED). We aimed to develop and validate a model, the COVID-19 ED pneumonia mortality index (CoV-ED-PMI), for predicting mortality in this population. We retrospectively included adult COVID-19 patients who visited EDs of five study hospitals in Texas and who were diagnosed with suspected pneumonia between March and November 2020. ⋯ The model was validated with good discriminative performance (AUC: 0.83, 95% confidence interval [CI]: 0.79-0.87), which was significantly better than the CURB-65 (AUC: 0.74, 95% CI: 0.69-0.79, p-value: < 0.001). The CoV-ED-PMI had a good predictive performance for 1-month mortality in COVID-19 patients with suspected pneumonia presenting at ED. This free tool is accessible online, and could be useful for clinical decision-making in the ED.

The effectiveness of Glasgow-Blatchford Score in early risk assessment of hemodialysis patients.
In the emergency departments (ED), the incidence of admission is increasing gradually due to gastrointestinal system (GIS) complications of hemodialysis (HD) patients. With this increasing number of patients, there are many classification systems developed in early risk assessment before endoscopy. In this study, we aimed to evaluate the Glasgow-Blatchford Score's (GBS) effectiveness in HD patients with suspected GIS hemorrhage in the ED. ⋯ When the patients were evaluated according to GBS parameters, a significant difference was found between the two groups in terms of pulse pressure, systolic blood pressure, hemoglobin value, melena, and accompanying comorbid diseases (p < 0.05). Of the 16 patients who presented to the ED due to syncope, 2 were in the GIS hemorrhage (+) group, and 14 patients were in the control group. In this study, we aimed to show that the increase in the number of admissions in the ED due to complications secondary to HD treatment and the accompanying serious changes in laboratory parameters may cause misleading results in patients with suspected GIS hemorrhage, and it is necessary to plan comprehensive and multi-center studies on new alternative scoring systems to GBS in specific patient groups such as HD patients.

We aimed to evaluate the impact of age, sex, and their interactions with provoking risk factors for deep vein thrombosis (DVT). In addition, we intended to provide additional insights on risk factors associated with the isolated distal versus proximal presentation of first symptomatic acute DVT, both being characterized by different prognosis. In the present analysis from the SWIss Venous ThromboEmbolism Registry (SWIVTER), we compared demographic and baseline characteristics in patients with isolated distal (n = 184; 35%) versus proximal (n = 346) DVT of the lower limbs without symptomatic pulmonary embolism, and identified factors related with the presenting thrombosis location. ⋯ In a multivariable analysis, recent surgery [odds ratio (OR) 2.92, 95% confidence interval (CI) 1.80-4.73] was independently associated with a diagnosis of isolated distal DVT, whereas cancer (OR 2.01, 95% CI 1.20-3.35), male sex aged 41 to 75 years (OR 2.21, 95% CI 1.33-3.67), and acute infection/sepsis (OR 2.71, 95% CI 1.29-5.66) with a diagnosis of proximal DVT. In SWIVTER, age, sex, and several provoking risk factors for VTE appeared to be related with the presenting location of first symptomatic DVT. Cancer, male sex, and acute infection/sepsis were associated with a proximal location of DVT, whereas recent surgery was associated with a distal presentation, likely acting as confounders for the association between thrombosis location and prognosis.

We studied the predictive value of the PaO2/FiO2 ratio for classifying COVID-19-positive patients who will develop severe clinical outcomes. One hundred fifty patients were recruited and categorized into two distinct populations ("A" and "B"), according to the indications given by the World Health Organization. Patients belonging the population "A" presented with mild disease not requiring oxygen support, whereas population "B" presented with a severe disease needing oxygen support. ⋯ Moreover, our work highlights that PaO2/FiO2 ratio, compared to inflammatory scores (hs-CRP, NLR, PLR and LDH) indicated to be useful in clinical managements, results to be the most reliable parameter to identify patients who require closer respiratory monitoring and more aggressive supportive therapies.
