BACKGROUND: Infection is a common complication in acute stroke. Whether or not preventive antibiotics reduce the risk of infection or even lead to a favorable outcome and reduction of mortality after a stroke still remains equivocal. This review was performed to update the current knowledge on the effect and possible benefits of prophylactic antibiotic therapy in patients with stroke. METHODS: A systematic review and meta-analysis of preventive antibiotics`effect on the incidence of infection, favorable outcome (mRS≤2) and mortality in patients with acute stroke is performed with relevant randomized controlled trials...

Background: Approximately one quarter of all nosocomial infections can be attributed to the urinary tract. The infections are supposed to be mainly caused by implantations of urethral catheters and stents. A new catheter design is introduced with the aim to lower the high number of nosocomial urethral infections. In order to avoid limitations to use, the design is first applied to conventional commercially available balloon catheters. Results: The main feature of the design is a sandwich layer on both sides of the catheter wall, which is composed of a fragmented base layer of silver capped by a thin film of poly(p-xylylene)...

BACKGROUND: Surveillance of health care-associated infections (HAIs) plays a key role in the hospital infection control program and reduction of HAIs. In India, most of the surveillance of HAIs is reported from private sector hospitals that do not depict the situation of government sector hospitals. Other studies do not confirm with the Centers for Disease Control and Prevention's (CDC) National Healthcare Safety Network (NHSN) surveillance criterion, or deal with ventilator-associated pneumonia (VAP) instead of ventilator-associated event (VAE)...

Achromobacter xylosoxidans is a Gram-negative aerobic bacterium first described by Yabuuchi and Ohyama in 1971. A. xylosoxidans is frequently found in aquatic environments. Abdominal, urinary tract, ocular, pneumonia, meningitis, and osteomyelitis are the most common infections. Infective endocarditis is rare. As far as we know, until now, only 19 cases have been described, including this current report. We report the case of community-acquired native valve endocarditis caused by A. xylosoxidans in an elderly patient without a concomitant diagnosis of a malignancy or any known immunodeficiency...

Background Deep venous thrombosis after any surgical operations is considered a preventable complication. Lower extremity bypass surgery is a commonly performed operation to improve blood flow to lower extremities in patients with severe peripheral arterial disease. Despite advances in endovascular surgery, lower extremity arterial bypass remains the gold standard treatment for severe, symptomatic peripheral arterial disease. The purpose of this study is to identify the clinical risk factors associated with development of deep venous thrombosis after lower extremity bypass surgery...

REVIEW
J Marcon, C G Stief, G Magistro
Urinary tract infections (UTIs) affect approximately 150 million people worldwide per year, causing annual health costs of over three billion dollars just in the USA. Every second woman experiences at least one UTI in her lifetime, with every one in four experiencing recurrence. Uncomplicated infections like single or recurrent cystitis and pyelonephritis can be distinguished from complicated disease. UTIs in men can spread to the male glands, causing prostatitis and epididymitis. Antibiotic therapy is the standard procedure for UTIs...

The recently approved combination of meropenem-vaborbactam (Vabomere™) is highly active against Gram-negative pathogens, especially KPC-producing, carbapenem-resistant Enterobacteriaceae We evaluated the efficacy of meropenem-vaborbactam against three clinically relevant isolates in a murine polynephritis model. Data indicated that the combination of meropenem-vaborbactam significantly increased the bacterial killing compared to the untreated controls. These data suggest that this combination may have utility in the treatment of complicated urinary tract infections due to KPC-producing, carbapenem-resistant Enterobacteriaceae...

The steps by which Escherichia coli strains harboring mutations related with fosfomycin (FOS) resistance arise and spread during urinary tract infections (UTI) is far to be understood. The aim of this study was to evaluate the effect of urine, pH and anaerobiosis on FOS activity against a set of isogenic strains carrying the most prevalent chromosomal mutations conferring FOS-resistance (ΔuhpT, ΔglpT, ΔcyaA and ΔptsI) and their combinations. Also, fosfomycin resistant E. coli clinical isolates from patients with UTI were studied...

A hallmark of bacterial biofilms is the production of an extracellular matrix (ECM) that encases and protects the community from environmental stressors. Biofilm formation is an integral portion of the uropathogenic Escherichia coli (UPEC) lifecycle. Approximately 2% of UPEC are cysteine auxotrophs. Here, we investigated how cysteine homeostasis impacted UPEC UTI89 strain biofilm formation and, specifically, the production of the ECM components curli and cellulose. Cysteine auxotrophs produced less cellulose and slightly more curli compared to wildtype (WT) strains, and cysteine auxotrophs formed smooth, non-rugose colonies...

BACKGROUND: Acute uncomplicated cystitis (AUC) is a common ailment in the urological setting. Guidelines for urinary tract infections are based on large-scale multi-centre, epidemiological and international studies. The objective of this observational study was to establish whether the results of a multi-centre study on the resistance profile of Escherichia coli (E. coli) in patients with AUC could be directly applied to an urological practice in a major European city or whether there are divergences in the resistance profile...
