Hospital infection

INTRODUCTION: Ongoing health reforms in the Military Health System (MHS) are expected to shift locations of ambulatory care for up to 1.9 million beneficiaries. We sought to model the impact of this policy by determining potentially avoidable hospitalizations in the MHS based on different primary care settings. MATERIALS AND METHODS: We used the MHS Data Repository to conduct a retrospective cross-sectional study of TRICARE Prime and Prime Plus beneficiaries aged 18 to 64 years during fiscal years 2018-2019...

INTRODUCTION: This work aimed to analyze whether breastfeeding is a predictive factor for admission to ICU or needing mechanical ventilation in children under 6 months with RSV+ respiratory infection. METHODS: A retrospective cohort study was performed in three hospitals. Binary and multiple logistic regression analyses were performed to evaluate the association of variables with admission to the ICU or receiving mechanical ventilation. RESULTS: We analyzed 414 admissions, of which 293 (70...

OBJECTIVES: Modern immunosuppressive regimens have reduced rejection episodes in renal allograft recipients but have increased the risk of opportunistic infections. Infections are considered to be the second leading cause of death after cardiovascular complications in renal allograft recipients. Data on opportunistic infections affecting the allograft itself are scarce. The present study describes the spectrum of renal opportunistic infections and their outcomes diagnosed on renal allograft biopsies and nephrectomy specimens...

Biofilm formation is an important virulence factor for methicillin-resistant Staphylococcus aureus (MRSA). The extracellular matrix of MRSA biofilms contains significant amounts of double-stranded DNA that hold the biofilm together. MRSA cells secrete micrococcal nuclease (Nuc1), which degrades double-stranded DNA. In this study, we used standard methodologies to investigate the role of Nuc1 in MRSA biofilm formation and dispersal. We quantified biofilm formation and extracellular DNA (eDNA) levels in broth and agar cultures...

BACKGROUND: Survivors of hospitalization for severe acute COVID-19 infection faced significant functional impairments necessitating discharge to inpatient rehabilitation facilities (IRFs) for intensive rehabilitation prior to discharge home. There remains a lack of large cohort studies of the functional outcomes of patients admitted to IRFs with COVID-19-related impairments and the relationship to patient-specific factors. OBJECTIVE: To characterize functional outcomes of patients admitted to IRFs for COVID-19-related debility and to investigate associations between functional outcomes and patient-specific factors...

BACKGROUND: Coronavirus disease 2019 (COVID-19) is associated with hypercoagulability. It remains uncertain whether ongoing anticoagulation for atrial fibrillation (AF) in patients who later contract COVID-19 improves clinical outcomes. OBJECTIVES: To compare chronic oral anticoagulation with no previous anticoagulation in patients with AF who contracted a COVID-19 infection concerning the outcomes of all-cause mortality, COVID-19 mortality, intensive care unit (ICU) admission, and hospitalization...

Characterized by symptoms that remain or appear for the first time within three months of SARS-CoV-2 infection, long COVID can manifest itself in different ways, including in non-hospitalized or asymptomatic cases. Thus, this study offers an overview of long COVID in Brazil, especially of its diagnosis, symptoms, and challenges for new health management. Data from a study that investigated long COVID in people affected by COVID-19 were used. These original data stem from a survey with adult Brazilians (aged 18 years or older) who had COVID-19 that collected information from March 14 to April 14, 2022, by a questionnaire on social media...

OBJECTIVES: Observational studies have suggested that SARS-CoV-2 infection may increase the burden of cerebral small vessel disease (CSVD). This study aims to explore the causal correlation between COVID-19 and the imaging markers of CSVD using Mendelian randomization (MR) methods. METHODS: Summary-level genome-wide association study (GWAS) statistics for COVID-19 susceptibility, hospitalization, and severity were utilized as proxies for exposure. Large-scale meta-analysis GWAS data on three neuroimaging markers of white matter hyperintensity, lacunar stroke, and brain microbleeds, were employed as outcomes...

BACKGROUND: Sofosbuvir, velpatasvir and voxilaprevir (SOF/VEL/VOX) is the recommended rescue therapy for patients with chronic hepatitis C infection who fail direct-acting antivirals (DAAs). Data are limited on the effectiveness of this treatment after the current first-line therapies. Our aim was to analyse the effectiveness and safety of SOF/VEL/VOX among patients failing sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB). METHODS: Retrospective multicentre study (26 Spanish hospitals), including chronic hepatitis C patients unsuccessfully treated with SOF/VEL or GLE/PIB, and retreated with SOF/VEL/VOX ± ribavirin for 12 weeks between December 2017 and December 2022...

The global increasing spread of multidrug-resistant organisms (MRDOs) is threatening the control of various infections in vulnerable populations and patient groups. One of the most affected groups is burn patients, who are prone to hyperinfection as they suffer from a hypermetabolic state and weakened immune barriers. Those patients also share the infection risk of patients hospitalized for a long time, including ventilator-associated pneumonia and urinary tract infections. While some preventative and therapeutic management styles are still controversial, there are some consensuses that we discuss here...

Neonate responses to pathogen-associated molecular patterns (PAMPS) differ from adults; such understanding is poor in Indian neonates, despite recognised significant infectious risk. Immune profiling analysis was undertaken of ten secreted mediators contextualised with cellular source induced by six PAMPs in umbilical cord (CB; n=21) and adult-blood (PBMC, n=14) from a tertiary care hospital in South India. Differential cytokine expression analysis (minimum log2-fold difference; adj p-value<0.05) identified bacterial PAMPs induced higher concentrations of IL-1β, IL-10, TNF-α in adults versus IL-8, GM-CSF, IFN-γ and IL-2 in CB...

BACKGROUND: Antimicrobial Stewardship Programs (ASP) have been applied widely in high-resource countries to prevent surgical site infections (SSI). Evidence favoring ASP interventions (ASPi) in gastrointestinal surgeries from low and middle-income countries has been limited, especially in antimicrobial prophylaxis. We aimed to investigate this gap at a Vietnamese tertiary hospital. METHODS: We conducted a retrospective cohort study on patients undergoing clean-contaminated surgeries in 2015 who received standard of care (SoC) or SoC + ASPi...

BACKGROUND: The Biofire® FilmArray® Meningitis/Encephalitis (ME) PCR panel covers 14 viral, bacterial, and fungal pathogens and has been implemented in many institutions worldwide. Post-marketing studies indicate a reduced sensitivity and overutilization underscoring the need for a more targeted usage. The aim of our study is to describe the utilization of the ME panel and to develop a diagnostic-stewardship based decision rule. MATERIALS: Adult patients, who underwent CSF analysis with the ME panel between August 2016 and June 2021 at the University Hospital Basel, were included...

BACKGROUND: Infections in humans are mainly caused by Aeromonas hydrophila , Aeromonas caviae , and Aeromonas veronii . In recent years, Aeromonas dhakensis has been recognized as widely distributed in the environment, with strong virulence. However, this bacterial infection usually does not appear in patients with pneumonia as the first symptom. CASE REPORT: We report a 26-year-old man who was admitted to the hospital with community-acquired pneumonia as the first symptom and developed serious conditions such as hemolytic uremic syndrome, multiple organ dysfunction, and hemorrhagic shock within a short period...

PURPOSE: Infection prevention and control (IPC) has a significant impact on the prognosis after pediatric cardiac surgery. This study aimed to provide surveillance data on the incidence and density of various infections during the COVID-19 epidemic and explore the influence of multi-drug resistant organisms (MDRO) on in-hospital prognosis after congenital heart disease surgery. METHODS: This single-center retrospective study included pediatric patients who underwent cardiac surgery between 2021 and 2022...

We investigated antibiotic resistance pattern in clinical bacterial pathogens isolated from in-patients and out-patients, and compared it with non-clinical bacterial isolates. 475 bacterial strains isolated from patients were examined for antibiotic resistance. Staphylococcus spp. (148; 31.1%) were found to be the most prevalent, followed by Klebsiella pneumoniae (135; 28.4%), Escherichia coli (74; 15.5%), Pseudomonas aeruginosa (65; 13.6%), Enterobacter spp. (28; 5.8%), and Acinetobacter spp. (25; 5.2%). Drug-resistant bacteria isolated were extended spectrum-β-lactamase K ...

BACKGROUND AND OBJECTIVES: Hospital-acquired pneumonia (HAP) is a life-threatening hospital-acquired infection contributing to poor outcomes and mortality. Though the prevalence is comparable, the burden of comorbidities and malnutrition further worsens the scenario in developing countries. Infective agents responsible for these infections vary between regions due to the variables involved. There is a dearth of data on clinico-microbiological correlates of HAP from Northern India...

BACKGROUND: The aims and ambitions of a surgeon in the early years of his professional career are to make a good reputation by providing excellent patient outcomes and avoiding complex and difficult surgeries. Revision lumbar spine surgeries (RLSSs) pose a significant challenge in terms of surgical management, as the moribund anatomy increases the risk of complications, adding to an unlikely outcome. OBJECTIVE: We conducted this study to determine the clinical indications and outcomes of RLSSs performed by an early career neurosurgeon...
