The present real-world analysis aimed to evaluate and describe the use of gamma-hydroxybutyric acid (GHB) for alcohol withdrawal syndrome (AWS) in hospitalized patients with diagnosis of liver cirrhosis. An 11-year observational retrospective study on patients affected by liver cirrhosis and alcohol use disorder (AUD) was performed using data from the Medical Toxicology Unit of Careggi University Hospital in Florence (Italy). A multivariate logistic regression was performed to estimate the probability of having a CIWA-Ar Max 3-4 during hospitalization, an AWS length > 36 h, a hospitalization > 9 days, and the probability of developing drowsiness. ⋯ GHB dose ≥ 100 mg/kg was not associated with the occurrence of drowsiness. Patients exposed to other sedative agents were more likely to experience drowsiness (OR 7.22 [95% CI 1.46-35.61]). The present real-world analysis underlines that GHB could be a valuable and safe option for the management of AWS in AUD patients affected by liver cirrhosis, also when administered early and even at higher than recommended dosages.

Ultrasound has become an increasingly valuable tool for the assessment of body composition, offering several applications and indications in clinical practice. Ultrasound allows bedside evaluation of muscle mass, fat compartments, and extravascular water, providing a cost-effective, portable, and accessible alternative to traditional methods, such as Dual-energy X-ray Absorptiometry (DEXA), Bioelectrical Impedance Analysis (BIA), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI). It is particularly useful in evaluating conditions, such as malnutrition, sarcopenia, and sarcopenic obesity, which require poor muscle mass to establish a diagnosis. ⋯ This article reviews the current applications of ultrasound in body composition assessment, highlighting the recent advancements and the correlation between ultrasound parameters and clinical outcomes. It discusses the advantages of ultrasound while also addressing its limitations, such as the need for standardized protocols and cut-off points. By providing a comprehensive update based on recent publications, this article aims to enhance the clinical utility of ultrasound in assessing and monitoring body composition and pave the way for future research in this field.

Instead of the ventricles, atria may be the cardiac structures mainly compressed during cardiopulmonary resuscitation (CPR). This study aimed to assess the prevalence and the mechanical characteristics of atrial compression, named the "atrial pump mechanism", in patients undergoing CPR. A retrospective cohort study was conducted on patients with witnessed refractory out-of-hospital cardiac arrest who were admitted to a tertiary referral center for extracorporeal CPR. ⋯ CPR was successful in four patients (80%) with atrial pump compared to 14 (40%) with no atrial pump mechanism (p = 0.155). In this series of selected patients with witnessed cardiac arrest, the prevalence of the atrial pump mechanism was not negligible. It may contribute to forward blood flow and the maintenance of cerebral perfusion during prolonged cardiopulmonary resuscitation.

Assessing patient frailty during triage evaluations has become increasingly relevant in Emergency Departments (ED). This study aimed to externally validating the Triage Frailty and Comorbidity (TFC) tool. This prospective study was conducted from June 1 to December 31, 2023. ⋯ In Decision Curve Analysis, it yielded higher net benefits up to a threshold probability of 0.30. The externally validated TFC tool appears very effective at identifying patients with increased risk of 90-day mortality after ED attendance. It could be implemented in clinical practice and enhance the predictive ability of standard triage systems.
