Background: The aim of the study was to evaluate the usefulness of the shock index (SI) and the TIMI risk index (TRI Thrombolysis in Myocardial Infarction Risk Index) one hour after successful primary percutaneous coronary intervention (pPCI) for predicting in-hospital mortality in patients with acute coronary syndrome complicated by cardiogenic shock (CS).
Methods: Forty-seven consecutive patients with acute myocardial infarction (AMI) complicated by CS were included in this prospective observational study. All patients underwent pPCI and obtained TIMI Grade Flow 3. SI and TRI were calculated one hour after pPCI.
Results: The primary endpoint-death from cardiovascular causes-occurred in 17 patients (36%). All calculated parameters were significantly higher in fatal CS than in the non-fatal CS group. A multivariate logistic regression model found only TRI to be an independent, significant predictor of death in the study group, with a proposed cut-off point of 66, with sensitivity 76.5% and specificity 83.3% (AUC 0.811, p = 0.00001).
Conclusions: The simple parameters of clinical assessment-SI and TRI-calculated one hour after a successful pPCI of infarct related artery are important predictors of death in AMI complicated by cardiogenic shock.

Hand-Assisted Laparoscopic Surgery (HALS) as an Alternative to Unplanned Laparoscopic Conversion to Open Surgery (LCOS) in Colectomies for Acute Diverticulitis.

Background: In difficult colorectal cases, surgeons may opt for a hand-assisted laparoscopic (HALS) colectomy or attempt a laparoscopic surgery that may require an unplanned conversion to open (LCOS). We aimed to compare the clinical outcomes of these 2 types of surgeries.
Methods: Colectomies for acute diverticulitis with a HALS or LCOS surgery were selected from the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) 2022 Targeted Colectomy Database.

Background And Aims: In cirrhosis, some patients display acute encephalopathy without hyperammonemia (NonHep E) which is not considered as overt hepatic encephalopathy (OHE). We aimed to assess the prevalence and characteristics of NonHep E and OHE in cirrhotic patients displaying acute encephalopathy, assess their respective prognosis and compare it to other causes of acute decompensation (AD) with/without hyperammonemia.
Approach And Results: We conducted a retrolective analysis from a prospective cohort of patients hospitalized for AD.
Background Aims: SBP leads to high rates acute kidney injury (AKI) -hepatorenal syndrome and mortality. Population-based studies on contemporary SBP epidemiology are needed to inform care. In a large, national cohort of patients diagnosed with SBP and confirmed by ascitic fluid criteria, we characterized ascitic fluid characteristics, in-hospital and 12-month mortality, AKI, and recurrent SBP.

Objective: Although the efficacy of high-flow nasal oxygen therapy in delaying or avoiding intubation in patients with hypoxemic respiratory failure has been studied, its potential for facilitating early weaning from invasive mechanical ventilation remains unexplored.
Methods: In this randomized controlled trial, 80 adults with acute hypoxemic respiratory failure requiring invasive mechanical ventilation for > 48 hours were enrolled and divided into two groups: conventional weaning and early weaning via high-flow nasal oxygen. In the conventional weaning group, the spontaneous breathing trial was performed after the PaO2/FiO2 ratio was ≥ 200, whereas in the high-flow nasal oxygen group, the spontaneous breathing trial was conducted earlier when the PaO2/FiO2 ratio was 150 - 200.
The aim of the Research to Practice column is to enhance the research critique abilities of both advanced practice registered nurses and emergency nurses, while also aiding in the translation of research findings into clinical practice. Each column focuses on a specific topic and research study. In this article, we used a scenario of chronic pain exacerbation to explore the study by Eucker et al.
