Preoperative Optimization of Patients Undergoing Orthopedic Foot and Ankle Surgery: A Single Institution Cohort.

Introduction: Careful preoperative patient preparation for orthopedic foot and ankle surgery can help manage postoperative expectations and avoid suboptimal outcomes. Our quality improvement initiative aimed to reduce emergency department (ED) visits within 30 days postsurgery by enhancing preoperative education.

Methods: We focused on four outcomes associated with receipt of written preoperative information: (1) related ED visits within 30 days of surgery, (2) average number of patient portal messages, (3) phone calls initiated by patients, and (4) staff team experience survey results.

Quorum sensing regulates virulence factors in the coral pathogen .

The bacterial pathogen causes disease in coral species worldwide. The mechanisms of coral colonization, coral microbiome interactions, and virulence factor production are understudied. In other model species, virulence factors like biofilm formation, toxin secretion, and protease production are controlled through a density-dependent communication system called quorum sensing (QS).

Risk factors and outcome of Pseudomonas aeruginosa bloodstream infections (PABSI) in hematological patients: a single center retrospective cohort study.

Purpose: Bloodstream infections caused by Pseudomonas aeruginosa (PABSI) in hematological patients are associated with high morbidity and mortality. We investigated the epidemiology, risk factors, and outcomes of PABSI at our center.

Methods: All adult hematological patients with PABSI between January 2013 and July 2023 were included.

[Summary of the S1 guideline on sustainability in intensive care and emergency medicine].

Background: Man-made climate change is one of the greatest challenges of the future. The course is being set in the current generation. As the healthcare sector contributes a considerable proportion of greenhouse gas emissions, measures to counteract this must be introduced as a matter of urgency.

Quorum sensing in Vibrio controls carbon metabolism to optimize growth in changing environmental conditions.

Bacteria sense population density via the cell-cell communication system called quorum sensing (QS). The evolution of QS and its maintenance or loss in mixed bacterial communities is highly relevant to understanding how cell-cell signaling impacts bacterial fitness and competition, particularly under varying environmental conditions such as nutrient availability. We uncovered a phenomenon in which Vibrio cells grown in minimal medium optimize expression of the methionine and tetrahydrofolate (THF) synthesis genes via QS.
