Utility of lung ultrasound to identify patients at risk of rehospitalization for acute decompensated heart failure.

Introduction: Residual congestion at hospital discharge predicts adverse outcomes in acute decompensated heart failure (ADHF). Lung ultrasound (LUS) is a reliable tool for assessing pulmonary congestion. This study aims to evaluate a simplified 4-zone LUS method for identifying heart failure patients at risk after discharge.

Obstetric hemorrhage risk assessment using the maximum allowable blood loss calculation: are we on the right track?

The clinical guidelines on postpartum hemorrhage from the Society of Obstetricians and Gynaecologists of Canada (SOGC) provide evidence-based recommendations structured around the 6Rs framework: Risk Assessment, Risk Reduction, Recognition and Evaluation, Reaction, Resuscitation, and Review. Since its publication, our institution has begun implementing all the guideline recommendations. One key recommendation is to calculate the Maximum Allowable Blood Loss (MABL) to reach a hemoglobin level of 70 g/L for every obstetric patient.

Surgical aortic valve replacement in patients with reduced ejection fraction. Prevalence and follow-up.

Introduction: Limited information exists on the prevalence and outcomes of patients undergoing surgical aortic valve replacement (SAVR) for aortic stenosis (AS) with reduced left ventricular ejection fraction (LVEF). This study aims to describe the number of AS patients undergoing SAVR with LVEF less than 55 % and quantify LVEF improvement at follow-up.

Material And Methods: We analyzed patients undergoing SAVR with LVEF less than 55 % and the number of patients that improved the LVEF at 6 months.

A scoping review for building a criticality-based conceptual framework of altered states of consciousness.

The healthy conscious brain is thought to operate near a critical state, reflecting optimal information processing and high susceptibility to external stimuli. Conversely, deviations from the critical state are hypothesized to give rise to altered states of consciousness (ASC). Measures of criticality could therefore be an effective way of establishing the conscious state of an individual.

Differential gene expression underlying the biosynthesis of Dufour's gland signals in .

Pheromones regulating social behavior are one of the most explored phenomena in social insects. However, compound identity, biosynthesis and their genetic basis are known in only a handful of species. Here we examined the gene expression associated with pheromone biosynthesis of two main chemical classes: esters and terpenes, using the social bee .
