Impact of vitamin C on the reduction of opioid consumption for acute musculoskeletal pain: A double-blind randomized control pilot study.

Introduction: Recent evidence has shown that vitamin C has analgesic and opioid sparing properties in immediate postoperative context. However, this has never been studied for acute musculoskeletal (MSK) emergency department (ED) injuries. The aim of this pilot study is to evaluate the feasibility of conducting a randomized placebo-controlled study to determine the opioid sparing and analgesic effect of vitamin C compared to placebo, in acute MSK injured ED patients.

Clinical characteristics and serological profiles of Lyme disease in children: a 15-year retrospective cohort study in Switzerland.

Background: Lyme disease (LD) is caused by and is the most common tickborne disease in the northern hemisphere. Although classical characteristics of LD are well-known, the diagnosis and treatment are often delayed. Laboratory diagnosis by serological testing is recommended for most LD manifestations.

Acanthamoeba Infection in a Hematopoietic Cell Transplant Recipient: Challenges in Diagnosis, Management, and Source Identification.

We report a case of Acanthamoeba infection in an HCT recipient with steroid-refractory GVHD. We highlight the multiple challenges that free-living ameba infections present to the clinician, the clinical laboratory, transplant infectious disease for review, hospital epidemiology if nosocomial transmission is considered, and public health officials, as exposure source identification can be a significant challenge. Transplant physicians should include Acanthamoeba infections in their differential diagnosis of a patient with skin, sinus, lung, and/or brain involvement.

Early detection of bacterial pneumonia by characteristic induced odor signatures.

Introduction: The ability to detect pathogenic bacteria before the onsets of severe respiratory symptoms and to differentiate bacterial infection allows to improve patient-tailored treatment leading to a significant reduction in illness severity, comorbidity as well as antibiotic resistance. As such, this study refines the application of the non-invasive Secondary Electrospray Ionization-High Resolution Mass Spectrometry (SESI-HRMS) methodology for real-time and early detection of human respiratory bacterial pathogens in the respiratory tract of a mouse infection model.

Methods: A real-time analysis of changes in volatile metabolites excreted by mice undergoing a lung infection by Staphylococcus aureus or Streptococcus pneumoniae were evaluated using a SESI-HRMS instrument.

Implementation of an Oncogeriatric Unit for Frail Older Patients with Breast Cancer: Preliminary Results.

(1) Background: Breast cancer (BC) has a high incidence in Europe, particularly in older adults. Traditionally under-represented in clinical trials, this age group is often undertreated due to ageism. This study aims to characterize frail older adults (≥70 years) with BC based on a comprehensive geriatric assessment, to guide individualized treatment decision-making.

Objectives: This study aimed to develop a taxonomy for classifying corrective actions following health care incidents in a Portuguese tertiary hospital.

Methods: The study utilized a multimethods design, combining qualitative and quantitative analyses of real-world data. Thematic analysis was performed, drawing on inductive and deductive approaches.

Automated surveillance for surgical site infections (SSI) in hospitals and surveillance networks-expert perspectives for implementation.

Background: This work aims at providing practical recommendations for implementing automated surveillance (AS) of surgical site infections (SSI) in hospitals and surveillance networks. It also provides an overview of the steps, choices, and obstacles that need to be taken into consideration when implementing such surveillance. Hands-on experience with existing automated surveillance systems of SSI (AS SSI systems) in Denmark, France, the Netherlands and Spain is described regarding trend monitoring, benchmarking, quality control, and research for surveillance purposes.

Multicenter Evaluation of the QIAstat-Dx and the BioFire Multiplex Panel Tests for the Detection of Respiratory Pathogens.

Syndromic multiplex panel testing enables simultaneous detection of multiple respiratory pathogens, but limited data is available on the comparative diagnostic performance of different testing systems. In this multicenter prospective study, we aimed to compare the QIAstat-Dx Respiratory Panel 2.0 (QIAstat-Dx-RP2.

Escherichia coli Nissle Improves Short-Chain Fatty Acid Absorption and Barrier Function in a Mouse Model for Chronic Inflammatory Diarrhea.

Background: Defects in SLC26A3, the major colonic Cl-/HCO3- exchanger, result in chloride-rich diarrhea, a reduction in short-chain fatty acid (SCFA)-producing bacteria, and a high incidence of inflammatory bowel disease in humans and in mice. Slc26a3-/- mice are, therefore, an interesting animal model for spontaneous but mild colonic inflammation and for testing strategies to reverse or prevent the inflammation. This study investigates the effect of Escherichia coli Nissle (EcN) application on the microbiome, SCFA production, barrier integrity, and mucosal inflammation in slc26a3-/- mice.

The effect of combining antibiotics on resistance: A systematic review and meta-analysis.

Background: Under which conditions antibiotic combination therapy decelerates rather than accelerates resistance evolution is not well understood. We examined the effect of combining antibiotics on within-patient resistance development across various bacterial pathogens and antibiotics.

Methods: We searched CENTRAL, EMBASE, and PubMed for (quasi)-randomised controlled trials (RCTs) published from database inception to 24 November 2022.

A core genome MLST scheme for Borrelia burgdorferi sensu lato improves insights into the evolutionary history of the species complex.

Multi-locus sequence typing (MLST) based on eight genes has become the method of choice for Borrelia typing and is extensively used for population studies. Whole-genome sequencing enables studies to scale up to genomic levels but necessitates extended schemes. We have developed a 639-loci core genome MLST (cgMLST) scheme for Borrelia burgdorferi sensu lato (s.

Fluorescent Probe for the pH-Independent Rapid and Sensitive Direct Detection of Urease-Producing Bacteria.

Urease-producing bacteria are highly relevant in medicine due to their role in various pathogenic processes and their impact on human health, causing serious medical conditions such as peptic ulcer disease, gastric cancer, and respiratory and urinary tract infections. In this work, we designed fluorescent polymeric particles (PNP_FITC) to enable the detection of urease-producing bacteria by targeting the enzymatic activity of urease. In particular, the PNP_FITC matrix is degraded by urease, leading to a measurable increase in the intensity of the fluorescent signal.

Electronic evaluation of infection risk from room environment and prior room occupants: the transmission from room environment events (TREE) measure.

Over a 2-year period, we identified Transmission from Room Environment Events (TREE) across the Johns Hopkins Health System, where the subsequent room occupant developed the same organism with the same antimicrobial susceptibilities as the patient who had previously occupied that room. Overall, the TREE rate was 50/100,000 inpatient days.

Viral and Immune Risk Factors of HIV Rebound after Interruption of Antiretroviral Therapy.

Background: Identifying risk factors for HIV rebound after treatment interruption is crucial for designing effective remission strategies.

Methods: Peripheral blood mononuclear cells from participants in the Zurich HIV Primary Infection Cohort (ZPHI, N=73) and ACTG study A5345 (N=44) were analyzed before ART interruption. We measured cell-associated HIV RNA, total HIV DNA, and proviral diversity (env gene).

Bridging the Gap: Subspecialty Telemedicine Consultations at a Level III Neonatal Intensive Care Unit.

Many neonatal intensive care units (NICUs) lack access to subspecialist consultants and may transfer patients requiring subspecialty care to referral facilities or seek informal consultation. The objective of this work was to evaluate the feasibility, acceptability, and impact of extending pediatric subspecialty services from a children's hospital to a level III NICU via teleconsultation and describe processes, facilitators, and challenges. Monitored consultations for 1 year and surveyed clinicians regarding feasibility, perceived benefits, and challenges.
