Impact of Pre-Analytical Time on the Recovery of Pathogens from Blood Cultures: Results from a Large Retrospective Survey.

Background Prompt identification of bloodstream pathogens is essential for optimal management of patients. Significant changes in analytical methods have improved the turnaround time for laboratory diagnosis. Less attention has been paid to the time elapsing from blood collection to incubation and to its potential effect on recovery of pathogens. We evaluated the performance of blood cultures collected under typical hospital conditions in relation to the length of their pre-analytical time. Methods We carried out a large retrospective study including 50,955 blood cultures collected, over a 30-month period, from 7,035 adult septic patients. Cultures were accepted by the laboratory only durin…

Nasal pressure swings as the measure of inspiratory effort in spontaneously breathing patients with de novo acute respiratory failure.

Abstract Background Excessive inspiratory effort could translate into self-inflicted lung injury, thus worsening clinical outcomes of spontaneously breathing patients with acute respiratory failure (ARF). Although esophageal manometry is a reliable method to estimate the magnitude of inspiratory effort, procedural issues significantly limit its use in daily clinical practice. The aim of this study is to describe the correlation between esophageal pressure swings (ΔPes) and nasal (ΔPnos) as a potential measure of inspiratory effort in spontaneously breathing patients with de novo ARF. Methods From January 1, 2021, to September 1, 2021, 61 consecutive patients with ARF (83.6% related to COVID…

Accuracy of Nasal Pressure Swing to Predict Failure of High-Flow Nasal Oxygen in Patients with Acute Hypoxemic Respiratory Failure

In a real-life cohort of patients with AHRF undergoing HFNO, ΔPnose showed excellent accuracy in predicting early failure, similar of that displayed by ROX. Giving that the decision to upgrade to NIV or MV was based on clinical variables, the high accuracy of ROX in predicting failure of HFNO is not surprising. The similar accuracy of ΔPnose (the only measurement that remained blinded to our clinical decision), strengthened the association with outcome, avoiding incorporation bias.

Implementation Strategies for Preventing Healthcare-Associated Infections across the Surgical Pathway: An Italian Multisociety Document

Healthcare-associated infections (HAIs) result in significant patient morbidity and can prolong the duration of the hospital stay, causing high supplementary costs in addition to those already sustained due to the patient’s underlying disease. Moreover, bacteria are becoming increasingly resistant to antibiotics, making HAI prevention even more important nowadays. The public health consequences of antimicrobial resistance should be constrained by prevention and control actions, which must be a priority for all health systems of the world at all levels of care. As many HAIs are preventable, they may be considered an important indicator of the quality of patient care and represent an importan…

Additional file 1 of Nasal pressure swings as the measure of inspiratory effort in spontaneously breathing patients with de novo acute respiratory failure

Additional file 1: eTable 1. Esophageal and nasal pressure swings according to acute respiratory failure etiology. Data are presented as median and interquartile ranges (IQR). eFigure 1. Pearson���s R showing correlations between ��Pes and ��Pnos at 24 hours after splitting the study population according to the NRS received. eFigure 2. Bland-Altman analysis assessing the agreement between ��Pes measured with esophageal manometry and estimated based on ��Pnos (��Pes, estimated) and computed as k����Pnos, where k is the average ratio of ��Pes to ��Pnos measured at baseline. At T2 Bland-Altman methods showed a bias of 0.1 cmH2O and 95% limits of agreement, LoA, from ���2.0 to 2.1 cmH2O (95.1% …
