Outcomes of patients with systolic heart failure presenting with sepsis to the emergency department of a tertiary hospital: a retrospective chart review study from Lebanon.

Objectives: Patients with congestive heart failure (CHF) may be at a higher risk of mortality from sepsis than patients without CHF due to insufficient cardiovascular reserves during systemic infections. The aim of this study is to compare sepsis-related mortality between CHF and no CHF in patients presenting to a tertiary medical centre.

Design: A single-centre, retrospective, cohort study.

Maxillary and mandibular contribution to the establishment of class II malocclusion in an adult Lebanese population.

Introduction: The main aim of this study was to describe the contribution of the maxilla and the mandible to the establishment of a Class II skeletal malocclusion in an adult Lebanese population. Secondary aims were to detect the presence of sex-based dimorphism and to study the influence of the vertical dimension on the Class II skeletal pattern.

Material And Method: A sample of 90 adults in skeletal Class II was recruited and equally distributed according to sex and vertical typology.

Use of Contrast-Enhanced Ultrasound for Confirmation of Central Venous Catheter Placement: Systematic Review and Meta-analysis.

Objectives: The purpose of this meta-analysis was to determine the sensitivity, specificity, and positive and negative predictive values of contrast-enhanced ultrasound (US) for confirming the tip location and placement of central venous catheters in adult patients.

Methods: A systematic review was performed using electronic databases, including MEDLINE, ClinicalTrials.gov, Cochrane, Embase, PubMed, and Scopus.
