Antibiotic allergy de-labeling in the intensive care unit: The prospective ADE-ICU study.

Purpose: Critically ill patients in the intensive care unit (ICU) are frequently prescribed antibiotics, with many reporting an antibiotic allergy label, predominantly to penicillin. Mislabeling contributes to suboptimal antibiotic use, increasing multidrug-resistant organisms and Clostridium difficile infections, and increased hospital length of stay. This prospective study implemented an antibiotic allergy assessment and testing program in the ICU, independently of clinical immunology/allergy services.

International multi-cohort analysis identifies novel framework for quantifying immune dysregulation in critical illness: results of the SUBSPACE consortium.

Progress in the management of critical care syndromes such as sepsis, Acute Respiratory Distress Syndrome (ARDS), and trauma has slowed over the last two decades, limited by the inherent heterogeneity within syndromic illnesses. Numerous immune endotypes have been proposed in sepsis and critical care, however the overlap of the endotypes is unclear, limiting clinical translation. The SUBSPACE consortium is an international consortium that aims to advance precision medicine through the sharing of transcriptomic data.

Targeting Sepsis: Disease Tolerance, Immune Resilience, and Compartmentalized Immunity.

Sepsis remains a major contributor to critical care mortality and morbidity worldwide. Despite advances in understanding its complex immunopathology, the compartmentalized nature of immune responses across different organs has yet to be fully translated into targeted therapies. This review explores the burden of sepsis on organ-specific immune dysregulation, immune resilience, and epigenetic reprogramming, emphasizing translational challenges and opportunities.

Sepsis: key insights, future directions, and immediate goals. A review and expert opinion.

This review explores the current landscape and evolving understanding of sepsis, highlighting both challenges and future directions. Sepsis remains a major global health burden, with diverse clinical presentations complicating timely diagnosis and management. Existing definitions, including the Sepsis-3 criteria, emphasize the importance of organ dysfunction, yet early sepsis detection remains limited by available tools.

Impact of Empirical Treatment Recommendations From 2017 European Guidelines for Nosocomial Pneumonia.

Background: The management of nosocomial pneumonia represents a major challenge in the ICU. European guidelines from 2017 proposed an algorithm for the prescription of empirical antimicrobial treatment based on medical history, local ecology, and severity (ie, presence or absence of septic shock). We assessed this algorithm's usefulness by comparing outcomes with and without guideline adherence in a population at high risk of multiresistance and mortality.

A Machine Learning Approach to Determine Risk Factors for Respiratory Bacterial/Fungal Coinfection in Critically Ill Patients with Influenza and SARS-CoV-2 Infection: A Spanish Perspective.

: Bacterial/fungal coinfections (COIs) are associated with antibiotic overuse, poor outcomes such as prolonged ICU stay, and increased mortality. Our aim was to develop machine learning-based predictive models to identify respiratory bacterial or fungal coinfections upon ICU admission. : We conducted a secondary analysis of two prospective multicenter cohort studies with confirmed influenza A (H1N1)pdm09 and COVID-19.

The unique metabolic and lipid profiles of patients with severe COVID-19 compared to severe community-acquired pneumonia: a potential prognostic and therapeutic target.

Background: Compare the changes and differences in metabolome and lipidome profiles among severe COVID-19 and CAP patients with ARF to identify biomarkers that could be used for personalized diagnosis, prognosis, and treatment.

Research Design And Methods: Plasma samples were taken at hospital admission (baseline) and on the 5 day of hospitalization (follow-up) and examined by RP-LC-QTOF-MS and HILIC-LC-QTOF-MS.

Results: 127 patients, 17 with CAP and 110 with COVID-19, were included.

Inflammatory response to SARS-CoV 2 and other respiratory viruses.

Introduction: Lower respiratory tract infections (LRTI) remain a significant global cause of mortality and disability. Viruses constitute a substantial proportion of LRTI cases, with their pandemic potential posing a latent threat. After the SARS-CoV-2 pandemic, the resurgence of other respiratory viruses, including Influenza and Respiratory Syncytial Virus responsible for LRTI has been observed especially in susceptible populations.

Prediction of multidrug-resistant bacteria (MDR) hospital-acquired infection (HAI) and colonisation: A systematic review.

Background: Hospital-Acquired Infections (HAI) represent a public health priority in most countries worldwide. Our main objective was to systematically review the quality of the predictive modeling literature regarding multidrug-resistant gram-negative bacteria in Intensive Care Units (ICUs).

Methods: We conducted and reported a Systematic Literature Review according to the recommendations of the PRISMA statement.

Epidemiology, ventilation management and outcomes of COVID-19 ARDS patients versus patients with ARDS due to pneumonia in the Pre-COVID era.

Background: Ventilation management may differ between COVID-19 ARDS (COVID-ARDS) patients and patients with pre-COVID ARDS (CLASSIC-ARDS); it is uncertain whether associations of ventilation management with outcomes for CLASSIC-ARDS also exist in COVID-ARDS.

Methods: Individual patient data analysis of COVID-ARDS and CLASSIC-ARDS patients in six observational studies of ventilation, four in the COVID-19 pandemic and two pre-pandemic. Descriptive statistics were used to compare epidemiology and ventilation characteristics.
