BACKGROUNDThe aim of this study was to determine the occurrence rate, demographics, clinical characteristics, and outcomes of patients with severe sepsis admitted to the emergency department.METHODSA prospective study evaluating all patients admitted to the emergency department unit in a public hospital of tertiary complexity in a six-month period was conducted. During this period, the emergency team was trained to diagnose sepsis. Patients who met the diagnostic criteria for severe sepsis were followed until their discharge from the hospital.RESULTSA total of 5,332 patients were admitted to the emergency department, and 342 met the criteria for severe sepsis/septic shock. The median (interquartile range) age of patients was 74 (65–84) years, and 52.1% were male. The median APACHE II and SOFA scores at diagnosis were 19 (15–25) and 5 (3–7), respectively. The median number of dysfunctional organ systems per patient was 2 (1–3). The median hospital length of stay was 10 (4.7–17) days, and the hospital mortality rate was 64%. Only 31% of the patients were diagnosed by the emergency department team as septic. About 33.5% of the 342 severe sepsis patients admitted to the emergency department were referred to an ICU, with a median time delay of 24 (12–48) hours. Training improved diagnosis and decreased the time delay for septic patients in arriving at the ICU.CONCLUSIONSThe occurrence rate of severe sepsis in the emergency department was 6.4%, and the rate of sepsis diagnosed by the emergency department team as well as the number of patients transferred to the ICU was very low. Educational campaigns are important to improve diagnosis and, hence, treatment of severe sepsis.

Background and aims: Expansion and morphological dysregulation of the bronchial vascular network occurs in asthmatic airways. Interleukin (IL) -17 and Rho-kinase (ROCK) are known to act in inflammation control and remodeling. Modulation of Rho-kinase proteins and IL-17 may be a promising approach for the treatment of asthma through the control of angiogenesis. Our objective was to analyze the effects of treatment with anti-IL17 and/or Rho-kinase inhibitor on vascular changes in mice with chronic allergic pulmonary inflammation. Methods: Sixty-four BALB/c mice, with pulmonary inflammation induced by ovalbumin were treated with anti-IL17A (7.5/µg per dose, intraperitoneal) and/or Rho-kinase inhibitor (Y-27632-10 mg/kg, intranasal), 1 h before each ovalbumin challenge (22, 24, 26, and 28/days). Control animals were made to inhale saline. At the end of the protocol, lungs were removed, and morphometric analysis was performed to quantify vascular inflammatory, remodeling, and oxidative stress responses. Results: Anti-IL17 or Rho-kinase inhibitor reduced the number of CD4+, CD8+, dendritic cells, IL-4, IL-5, IL-6, IL-10, IL-13, IL-17, Rho-kinase 1 and 2, transforming growth factor (TGF-β), vascular endothelial growth factor (VEGF), nuclear factor (NF)-KappaB, iNOS, metalloproteinase (MMP)-9, MMP-12, metalloproteinase inhibitor-1 (TIMP-1), FOXP-3, signal transducer and activator of transcription 1 (STAT1) and phospho-STAT1-positive cells, and actin, endothelin-1, isoprostane, biglycan, decorin, fibronectin and the collagen fibers volume fraction compared with the ovalbumin group ( p < 0.05). The combination treatment, when compared with anti-IL17, resulted in potentiation of decrease in the number of IL1β- and dendritic cells-positive cells. When we compared the OVA-RHO inhibitor-anti-IL17 with OVA-RHO inhibitor we found a reduction in the number of CD8+ and IL-17, TGF-β, and phospho-STAT1-positive cells and endothelin-1 in the vessels ( p < 0.05). There was an attenuation in the number of ROCK 2-positive cells in the group with the combined treatment when compared with anti-IL17 or Rho-kinase inhibitor-treated groups ( p < 0.05). Conclusion: We observed no difference in angiogenesis after treatment with Rho-kinase inhibitor and anti-IL17. Although the treatments did not show differences in angiogenesis, they showed differences in the markers involved in the angiogenesis process contributing to inflammation control and vascular remodeling.

OBJECTIVES: To analyze functional recovery groups of critically ill COVID-19 survivors during their hospital stay and to identify the associated factors. DESIGN: Prospective observational multicenter study. SETTING: Demographic, clinical, and therapeutic variables were collected, and physical and functional status were evaluated. The Barthel index was evaluated at three time points: 15 days before hospitalization, at ICU discharge, and at hospital discharge from the ward. PATIENTS: Patients with functional independence before COVID-19 diagnosis were recruited from four hospitals and followed up until hospital discharge. MEASUREMENTS AND MAIN RESULTS: Three groups of functional recovery were described for 328 patients: functional independence ( n = 144; 44%), which included patients who preserved their functional status during hospitalization; recovered functionality ( n = 109; 33.2%), which included patients who showed dependence at ICU discharge but recovered their independence by hospital discharge; and functional dependency ( n = 75; 22.8%), which included patients who were dependent at ICU discharge and had not recovered their functional status at hospital discharge. The factors associated with becoming functionally dependent at ICU discharge were time to out-of-bed patient mobilization (odds ratio [OR], 1.20; 95% CI, 1.11–1.29), age (OR, 1.02; 95% CI, 1.01–1.04), hyperglycemia (OR, 2.52; 95% CI, 1.56–4.07), and Simplified Acute Physiology Score (OR, 1.022; 95% CI, 1.01–1.04). Recovery to baseline independence during ward stays was associated with ICU length of stay (OR, 0.97; 95% CI, 0.94–0.99) and muscle strength (Medical Research Council test) at ICU discharge (OR, 1.13; 95% CI, 1.08–1.18). CONCLUSIONS: Age, hyperglycemia, and time for patient mobilization out of bed were independent factors associated with becoming physically dependent after their ICU stay. Recovery of physical function at hospital discharge was associated with muscle strength at ICU discharge and length of ICU stay.
