While high-sensitivity (hs) troponin (cTn) has been associated with shorter emergency department (ED) length of stay (LOS) and decreased hospital admissions outside the United States (US), concerns have been raised that it will have opposite effects in the US. In this study, we aimed to compare ED LOS, admissions, and acute coronary syndrome (ACS) diagnoses before and after the implementation of hs-cTn. ⋯ In this single-center study, transition to hs-cTn was associated with an increased ED LOS, decreased admissions, and no substantial change in cardiac risk stratification testing, cardiology consultation, or ACS diagnoses.

This study aimed to examine the use of point-of-care ultrasonography (POCUS) in detecting diaphragmatic dysfunction (DD) and evaluate its ability to predict noninvasive mechanical ventilation (NIV) failure in patients presented to the emergency department with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). ⋯ DD has high sensitivity and specificity in predicting NIV failure in patients admitted to the emergency department with AECOPD. DD can be assessed by an experienced clinician noninvasively using POCUS in emergency departments.

Observational Study
Outcomes of a novel ED observation pathway for mild traumatic brain injury and associated intracranial hemorrhage.
Recent studies have shown that the majority of non-anticoagulated patients with small subdural or subarachnoid intracranial hemorrhage (ICH) in the setting of mild traumatic brain injury do not experience clinical deterioration or require neurosurgical intervention. We implemented a novel ED observation pathway to reduce unnecessary admissions among patients with ICH in the setting of mild TBI (complicated mild TBI, cmTBI). ⋯ ED observation for patients with cmTBI resulted in an 82% pathway completion rate, including outside hospital transfers. These results suggest that patients with cmTBI may be safely discharged from the ED after a brief period of observation. Our pathway protocol and implementation involved neurosurgical consultation and the ability to perform repeat neurologic exams in the ED. Future studies should examine the feasibility of non-transfer protocols for appropriately selected patients and access to neurosurgical expertise in the community setting.

An index combining respiratory rate and oxygenation (ROX) has been introduced, and the ROX index is defined as the ratio of oxygen saturation by pulse oximetry/fraction of inspired oxygen to respiratory rate. In sepsis, hypoxemia and tachypnea are commonly observed. We performed this study to investigate the association between the ROX index and 28-day mortality in patients with sepsis or septic shock. ⋯ The ROX index was lower in nonsurvivors than in survivors, and a ROX index less than or equal to 10 was an independent prognostic factor for 28-day mortality in patients with sepsis or septic shock. Therefore, the ROX index could be used as a prognostic marker in sepsis.

Hepatic portal venous gas: A case report and analysis of 131 aatients using PUBMED and MEDLINE database.
Hepatic portal pneumatosis has a high mortality rate, and whether surgical intervention is necessary remains controversial. This experiment retrospectively analyzed the etiology, treatment methods and prognosis of adult patients with hepatoportal pneumocele to provide a theoretical basis for the treatment of this disease. ⋯ Etiology should be actively explored and surgical treatment is necessary.
