Background: Staphylococcus aureus is a Gram-positive bacterium that causes severe illnesses in the human population. The capacity of S. aureus strains to form biofilms on biotic and abiotic surfaces creates serious problems for treatment of hospital infections and has stimulated efforts to develop new means of specific protection or immunotherapy. Material and Methods: We found that rabbit serum raised against crude concentrated S. aureus liquid culture significantly decreased the development of staphylococcal biofilm in vitro ...

BACKGROUND: Fear surrounds Ebola Virus Disease (EVD) because it is highly infectious. Yet members of the Serious Communicable Diseases Unit (SCDU) at Emory University Hospital (EUH) had to overcome that fear when caring for patients with EVD. PURPOSE: The analysis reported here illustrates how the members of EUH's SCDU tacitly enacted high reliability (HR) principles while caring for patients with EVD. METHODS: A qualitative study was conducted to describe the experience of members of the EUH SCDU who worked with EVD patients in 2014...

Hand hygiene practice in hospitals is unfortunately still widely insufficient, even though it is known that transmitting pathogens via hands is the leading cause of healthcare-associated infections. Previous research has shown that improving knowledge, providing feedback on past behaviour and targeting social norms are promising approaches to improve hand hygiene practices. The present field experiment was designed to direct people on when to perform hand hygiene and prevent forgetfulness. This intervention is the first to examine the effect of inducing injunctive social norms via an emoticon-based feedback system on hand hygiene behaviour...

Nosocomial, hospital-acquired or health care-associated infections occur worldwide, affecting both developed and developing countries. This results in a prolonged hospital stay, increased antimicrobial resistance, increased mortality rate, and significant financial burden on the health care system. Routine preventive measures have led to the decrease in infection spreading; however, it cannot successfully prevent all of them, making a place for the development of new strategies, including probiotics. The aim of this review was to summarize available evidence of the role of probiotics in the prevention of nosocomial infections in children...

OBJECTIVES: The vascular endothelium is a major target of sepsis-induced events, and endothelial activation accounts for much of the pathology of sepsis. Urinary tract infections and pneumonia caused by Escherichia coli are among of the most common infections causing sepsis in both community and hospital settings. Currently, there are no approved drugs on the market to treat the underlying pathophysiology of sepsis. The aim of this study is to elucidate the molecular mechanism by which E...

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings...

BACKGROUND: Central line-associated bloodstream infections (CLABSIs) cause substantial morbidity and increase antimicrobial use and length of stay among hospitalized children in the United States. CLABSI occurs more frequently among high-risk pediatric patients, such as those with intestinal failure (IF) who are parenteral nutrition (PN) dependent. Following an increase in CLABSI rates, a quality improvement (QI) initiative was implemented. METHODS: Using QI methodology, an enhanced central venous catheter (CVC) maintenance bundle was developed and implemented on 2 units for pediatric PN-dependent patients with IF...

CONTEXT: Hypothyroidism is a significant cause of pericardial effusion. However, large pericardial effusions due to hypothyroidism are extremely rare. Hormone replacement therapy is the cornerstone of treatment for hypothyroidism and regular follow-up of patients after initiation of the therapy is indicated. Herein, the case of a 70-year-old woman with a massive pericardial effusion due to Hashimoto's disease is presented. ISSUES: A 70-year-old female from a rural village on the island of Crete, Greece, was admitted to our hospital due to a urinary tract infection...

INTRODUCTION: Hospital readmissions are not only associated with increased mortality, morbidity and costs but also, with current healthcare reform, tied to significant financial and administrative penalties. Some studies show that patients undergoing vascular surgery may have higher than average readmission rates. The recently released Nationwide Readmission Database (NRD) is the most comprehensive national source of readmission data, gathering discharge information from 22 geographically dispersed states, accounting for 51...

INTRODUCTION: Pneumococcal conjugate vaccines (PCVs) prevent disease through both direct protection of vaccinated individuals and indirect protection of unvaccinated individuals by reducing nasopharyngeal (NP) carriage and transmission of vaccine-type (VT) pneumococci. While the indirect effects of PCV vaccination are well described, the PCV coverage required to achieve the indirect effects is unknown. We will investigate the relationship between PCV coverage and VT carriage among undervaccinated children using hospital-based NP pneumococcal carriage surveillance at three sites in Asia and the Pacific...

BACKGROUND: Traditional methods for molecular epidemiology of Neisseria gonorrhoeae are suboptimal. Whole-genome sequencing (WGS) offers ideal resolution to describe population dynamics and to predict and infer transmission of antimicrobial resistance, and can enhance infection control through linkage with epidemiological data. We used WGS, in conjunction with linked epidemiological and phenotypic data, to describe the gonococcal population in 20 European countries. We aimed to detail changes in phenotypic antimicrobial resistance levels (and the reasons for these changes) and strain distribution (with a focus on antimicrobial resistance strains in risk groups), and to predict antimicrobial resistance from WGS data...

BACKGROUND: Multimodal interventions are effective in increasing hand hygiene (HH) compliance amongst healthcare workers, but it is not known whether such interventions are cost-effective outside high-income countries. AIM: To evaluate the cost-effectiveness of multimodal hospital interventions to improve hand hygiene (HH) compliance in a middle-income country. METHOD: We adopted a conservative approach by developing a model to determine whether reductions in Methicillin-resistant Staphylococcus aureus bloodstream infections (MRSA-BSI) alone would make HH interventions cost-effective in intensive care units (ICUs)...

Microbial invasion and colonization of the skin and underlying soft tissues are among the most common types of infections, becoming increasingly prevalent in hospital settings. Systemic antibiotic chemotherapies are now extremely limited due to emergence of drug-resistant Gram-positive and multidrug-resistant Gram-negative bacterial strains. Topical administration of antimicrobials provides an effective route for the treatment of skin and soft tissue infections (SSTIs). Therefore, the development of new and effective materials for the delivery of these agents is of paramount importance...
