Article Abstract
Purpose Of Review: Nosocomial infections are common and are associated with considerable morbidity and mortality. The continuing evolution of multidrug resistant pathogens and ineffective therapy for the infections they cause has stimulated interest in the potential of probiotic products to prevent nosocomial infections. Probiotics are viable microorganisms that colonize the host and exert antibacterial and immunomodulatory effects. This article will review the current evidence for probiotics in preventing nosocomial infections, particularly pneumonia in a diverse population of critically ill patients.
Recent Findings: Currently, there are insufficient data to conclusively determine whether probiotics are beneficial in the prevention of nosocomial infections, particularly nosocomial pneumonia. Most of the current literature is limited by poor trial design, inadequate blinding, small study samples, and poorly defined endpoints.
Summary: Probiotic products reduce pathogenic colonization of the host. Despite the theoretical plausibility, there is currently insufficient evidence that probiotic products reduce the incidence of nosocomial pneumonia. Large, multicenter, randomized clinical trials utilizing a rigorous, invasive diagnostic approach to nosocomial pneumonia need to be performed to prospectively evaluate the utility of probiotic products. In addition, bench research needs to be performed to select the most appropriate probiotic formulation for different clinical applications.

Addition of macrolide antibiotics for hospital treatment of community-acquired pneumonia.
J Infect Dis
December 2024
The National Institute for Health Research Oxford Biomedical Research Centre, University of Oxford, Oxford, UK.
Background: Current guidelines recommend combining a macrolide with a β-lactam antibiotic for the empirical treatment of moderate-to-high severity community-acquired pneumonia (CAP); however macrolide use is associated with potential adverse events and antimicrobial resistance.
Methods: We analysed electronic health data from 8,872 adults in Oxfordshire, UK, hospitalised with CAP between 01-January-2016 and 19-March-2024, who received either amoxicillin or co-amoxiclav as initial treatment. We examined the effects of adjunctive macrolides on 30-day all-cause mortality, time to hospital discharge, and changes in Sequential Organ Failure Assessment (SOFA) score, using inverse probability treatment weighting to address confounding by baseline severity.
Antimicrobial Resistance Pattern, Predisposing Factors, and Outcome of Serratia Infection in Patients Treated at a Secondary-Care Hospital in Oman: A 5-Year Retrospective Study.
Adv Biomed Res
October 2024
Department of Community Medicine, All India Institute of Medical Sciences, Mangalagiri, Andhra Pradesh, India.
Background: has emerged as an important nosocomial opportunistic pathogen, often associated with serious infections. We investigated the antimicrobial resistance trends, predisposing factors, and infection outcomes associated with isolated in a secondary-care hospital in Oman.
Materials And Methods: A retrospective study was conducted at a secondary-care hospital in the northern region of Oman after receiving approval from the research ethics and approval committee of Oman.
Efficacy of quality improvement interventions on antibiotic prescription practices for ventilator-associated pneumonia at a tertiary care centre: a prospective pre-post interventional study.
BMJ Open Qual
December 2024
Department of Microbiology, All India Institute of Medical Sciences, Patna, Bihar, India.
Background: Ventilator-associated pneumonia (VAP) is a prevalent nosocomial infection in the intensive care unit (ICU), significantly increasing patient morbidity, mortality, and healthcare costs. Effective management is essential, particularly in the context of antimicrobial resistance and the frequent use of antibiotics in ICUs.
Methods: This prospective pre-post interventional study was conducted in the medical ICU of a tertiary care centre, over 6 months.
Does the treatment modality affect nosocomial pneumonia and other in-hospital outcomes in patients with combined injuries to the ribs and clavicle? A propensity score weighted analysis of a retrospective cohort.

Objective: What is the effect of surgical or conservative treatment on the in-hospital outcomes of patients with combined fractures of the clavicle and ribs?
Design: Retrospective cohort study.
Setting: Two level-1 trauma centers and academic teaching hospitals in Boston, Massachusetts.
Patients: All adult patients with a clavicle fracture and ≥3 rib fractures admitted from 2016 to 2021.
Length of hospital stay, delayed pneumonia diagnosis and post-discharge mortality. The Pneumonia in Italian Acute Care for Elderly units (PIACE)-SIGOT study.
Eur J Intern Med
December 2024
Unit of Geriatrics, Department of Internal Medicine, Azienda Ospedaliera S. Giovanni-Addolorata, Rome, Italy.
Background: High-income countries are currently decreasing length of hospital stay (LOS), with the aim of improving resource utilization. Little is known about the contribution of LOS to short-term post-discharge mortality in older patients with pneumonia.
Aim: to identify factors independently associated with LOS and to determine whether LOS predicts 3-month post-discharge death in older patients hospitalized for pneumonia.
