Neurological complications associated with influenza in season 2017/18 in Austria- a retrospective single center study.

Background: Neurological complications associated with influenza (NCI) are rare events in adults with seasonal influenza. Information about the characteristics of neurological complications and the burden of disease has been limited to case reports, mainly during the pandemic 2009. Influenza-associated encephalopathy/encephalitis (IAE) is one of the most severe and frequently reported NCI, mostly caused by influenza A.

Disinfection of contaminated metal implants with an Er:YAG laser.

Infections related to orthopedic procedures are considered particularly severe when implantation materials are used, because effective treatments for biofilm removal are lacking. In this study, the relatively new approach for infection control by using an erbium:yttrium-aluminum-garnet (Er:YAG) laser was tested. This laser vaporizes all water containing cells in a very effective, precise, and predictable manner and results in only minimal thermal damage.

Vaginal colonization of extended-spectrum beta-lactamase-producing bacteria during pregnancy: An observational study.

Objective: Extended-spectrum beta-lactamase (ESBL) is a rapidly evolving enzyme that cleaves beta-lactam-containing antibiotics, forming resistance to certain types of antibiotics, such as penicillin, cephalosporins and monobactams. Colonization with ESBL-producing bacteria during pregnancy is harmful, however this topic is currently underrepresented in the literature.

Study Design: Using a retrospective design, we analyzed data of all consecutive pregnant women who were identified with a vaginal colonization of ESBL-producing bacteria from 2011 to 2016 at the Medical University of Vienna, Department of Obstetrics and Gynecology.

Infection control and risk factors for acquisition of carbapenemase-producing enterobacteriaceae. A 5 year (2011-2016) case-control study.

Background: Carbapenemase-producing enterobacteriaceae (CPE) are a major threat for severely ill patients. However, only limited data on the epidemiology and on evidence-based infection prevention and control measures are available. The aim of this study was to investigate the epidemiology of patients with CPE, characterizing the CPE isolates by their resistance mechanisms and genetic similarity, to explore risk factors for their acquisition, and to evaluate the effectiveness of the current CPE infection control measures.

Outbreak of Vancomycin-resistant Enterococcus faecium in Interventional Radiology: Detection Through Whole-genome Sequencing-based Surveillance.

Background: Vancomycin-resistant enterococci (VRE) are a major cause of hospital-acquired infections. The risk of infection from interventional radiology (IR) procedures is not well documented. Whole-genome sequencing (WGS) surveillance of clinical bacterial isolates among hospitalized patients can identify previously unrecognized outbreaks.

Analysis of the challenges in implementing guidelines to prevent the spread of multidrug-resistant gram-negatives in Europe.

Objective: The main objective of the study was to investigate major differences among European countries in implementing infection prevention and control (IPC) measures and reasons for reduced compliance.

Setting: Europe.

Statistical outbreak detection by joining medical records and pathogen similarity.

We present a statistical inference model for the detection and characterization of outbreaks of hospital associated infection. The approach combines patient exposures, determined from electronic medical records, and pathogen similarity, determined by whole-genome sequencing, to simultaneously identify probable outbreaks and their root-causes. We show how our model can be used to target isolates for whole-genome sequencing, improving outbreak detection and characterization even without comprehensive sequencing.

Three years' experience of dialysis event surveillance.

Background: The main study aim was to track infections, evaluate performance, and identify opportunities for improved practice since infections, especially those associated with multidrug-resistant organisms, are the second most common cause of death among end-stage renal disease patients.

Methods: This study describes the establishment of baseline dialysis event surveillance at a large dialysis center. Every month, the dialysis center staff reported the total number of maintenance hemodialysis patients to the department of infection control and hospital epidemiology.

Impact of participation in a surgical site infection surveillance network: results from a large international cohort study.

Background: Surveillance of surgical site infections (SSIs) is a core component of effective infection control practices, though its impact has not been quantified on a large scale.

Aim: To determine the time-trend of SSI rates in surveillance networks.

Methods: SSI surveillance networks provided procedure-specific data on numbers of SSIs and operations, stratified by hospitals' year of participation in the surveillance, to capture length of participation as an exposure.

Irritative potency of selected wound antiseptics in the hen's egg test on chorioallantoic membrane to predict their compatibility to wounds.

Antiseptics are being used for prevention of infections in acute wounds and for treatment of infections in acute and chronic wounds. However, some antiseptics' high tissue toxicity might delay the healing process. The aim of this study was to investigate the tissue toxicity of preferentially used wound antiseptics and the influence of antiphlogistic additives via the hen's egg test on the chorioallantoic membrane (HET-CAM).

Bacterial Extracellular DNA Production Is Associated with Outcome of Prosthetic Joint Infections.

In a retrospective study the association of the production of extracellular DNA (eDNA) in biofilms of clinical staphylococcal isolates from 60 patients with prosthetic joint infection (PJI) and the clinical outcome were investigated. Data from a previous study on eDNA production determined in 24-hour biofilms of staphylococcal isolates (S n=30, n=30) was correlated with the patients' clinical outcome after 3 and 12 months. Statistical analysis was performed using either the Spearman's rank correlations test or the t-test.

Prevalence and burden of hepatitis D virus infection in the global population: a systematic review and meta-analysis.

Objective: Hepatitis D virus (HDV) is a defective virus that completes its life cycle only with hepatitis B virus (HBV). The HBV with HDV super-infection has been considered as one of the most severe forms of the chronic viral hepatitis. However, there is a scarcity of data on the global burden of HDV infection.

Epidemiology of Urinary Tract Infections in HIV Positive Patients at a Tertiary Care University Hospital in Central Europe (2011 - 2016).

Objectives: There is limited published data concerning the recent epidemiology of urinary tract infections (UTI) in HIV-patients, thus we analysed independent risk factors for UTI in HIV positive individuals and antimicrobial resistance rates of E. coli to antimicrobial agents commonly used in UTI. To determine the prevalence of symptomatic urinary tract infections (UTI) in HIV-patients, we performed a retrospective case-control study.

Incidence of risk factors for bloodstream infections in patients with major burns receiving intensive care: A retrospective single-center cohort study.

Objectives: The objective was primarily to identify risk factors for bloodstream infections (BSI) caused by different pathogens.

Methods: A retrospective single-center cohort study was performed on 472 burn patients with an abbreviated burn severity index (ABSI)≥3, a total burn surface area (TBSA)≥10%, and an ICU stay of at least 24h. Risk factors for different BSI pathogens were analyzed by competing risks regression model of Fine and Gray.

Can long-term historical data from electronic medical records improve surveillance for epidemics of acute respiratory infections? A systematic evaluation.

Background: As the deployment of electronic medical records (EMR) expands, so is the availability of long-term datasets that could serve to enhance public health surveillance. We hypothesized that EMR-based surveillance systems that incorporate seasonality and other long-term trends would discover outbreaks of acute respiratory infections (ARI) sooner than systems that only consider the recent past.

Methods: We simulated surveillance systems aimed at discovering modeled influenza outbreaks injected into backgrounds of patients with ARI.

Evaluation of three experimental in vitro models for the assessment of the mechanical cleansing efficacy of wound irrigation solutions.

The aim of this study was to compare different wound-rinsing solutions to determine differences in the efficiency and to evaluate three different in vitro models for wound cleansing. Different wound-rinsing solutions (physiological saline solution, ringer lactate solution for wound irrigation, water and a solution containing polihexanide and the surfactant undecylenamidopropyl-betain) were applied on standardised test models (one- and three-chamber model, flow-cell method and a biofilm model), each challenged with three different standardised wound test soils. In the one-chamber model saline showed a better effect on decontaminating proteins than the ringer lactate solution.

Aims: To describe the epidemiological investigation of an outbreak of B. cepacia bacteraemia.

Molecular epidemiology of multidrug-resistant clinical isolates of Acinetobacter baumannii : A 10-year analysis in a large tertiary care university hospital in central Europe with international admissions.

Background: Over the last 10 years, multidrug resistant Acinetobacter baumannii has been spreading worldwide as emerging microorganisms that negatively impact on the outcome of in-hospital patients.

Methods: Between 2007 and 2016, all isolates of patients of the Vienna General Hospital (VGH), tested positive for multidrug resistant Acinetobacter baumannii (MDR A. baumannii) strains, were investigated with respect to their genetic relationship.

Individualized correction of insulin measurement in hemolyzed serum samples.

Insulin measurement plays a key role in the investigation of patients with hypoglycemia, subtype classification of diabetes mellitus, insulin resistance, and impaired beta cell function. However, even slight hemolysis can negatively affect insulin measurement due to RBC insulin-degrading enzyme (IDE). Here, we derived and validated an individualized correction equation in an attempt to eliminate the effects of hemolysis on insulin measurement.
