The prevention of catheter-related blood stream infections (CRBSI) in hemodialysis (HD) patients remains a challenge because of high morbidity and mortality associated to CRBSI. Alternative locking solutions (ALS) containing an antithrombotic substance with additional antimicrobial or antibiofilm properties (citrate, ethylenediaminetetraacetic acid [EDTA], 70% ethanol, thrombolytics) with or without the addition of molecules with specific antimicrobial activity (antibiotics, taurolidine, paraben-methylene-blue) has been proposed with the aim to prevent or eradicate intraluminal biofilm colonization and subsequent CRBSI...

Central line associated blood stream infections (CLABSI) are the most common complication of central catheters in neonates. These infections increase length of hospital stay, hospital costs and impact on mortality and morbidities. We performed a quasi-experimental study, over 24 months, utilising a pre-post design to determine the impact checklists had on central line infections. We introduced checklists for insertion, daily maintenance and procedural access based on the existing clinical guideline. Infections and compliance were monitored and reported back to the unit each month...

Vitamin A promotes development of mucosal tolerance and enhances differentiation of regulatory T cells. Vitamin A deficiency impairs epithelial integrity, increasing intestinal permeability. We hypothesized that higher vitamin A levels would reduce risk of graft versus host disease through reduced intestinal permeability, reduced mucosal injury, and reduced lymphocyte homing to the gut. We tested this hypothesis in a cohort study of 114 consecutive patients undergoing allogeneic stem cell transplant. Free vitamin A levels were measured in plasma at day 30 post-transplant...

BACKGROUND: Healthcare-associated infections (HAIs) are responsible for many deaths of hospitalized patients each year. Patients with prolonged hospitalization are at high risk for HAIs. Increased efforts have been made to decrease these infections, but a recent report from the Centers for Disease Control suggests that some HAIs may be increasing. We hypothesized that HAIs would remain frequent among cardiac surgery patients with prolonged intensive care unit stay and would be associated with increased mortality...

Pyocystis, empyema cystis, vesical empyema are all terms that describe the purulent filled bladder that may develop in patients with defunctionalized bladders such as after supravesical urinary diversion without cystectomy or in patients with end-stage renal disease with anuria. It is a severe form of lower urinary tract infection. In addition to the local symptoms of suprapubic pain and malodorous discharge, the condition can be more serious with bacterial dissemination into the blood stream and ensuing sepsis and even mortality...

Enadenotucirev (EnAd) is a group B oncolytic adenovirus developed for systemic delivery and currently undergoing clinical evaluation for advanced cancer therapy. For differentiated carcinomas, systemic delivery would likely expose virus particles to the basolateral surface of cancer cells rather than the apical surface encountered during natural infection. Here, we compare the ability of EnAd and adenovirus type-5 (Ad5) to infect polarised colorectal carcinoma cells from the apical or basolateral surfaces. Whereas Ad5 infection was more efficient via the apical than basolateral surface, EnAd readily infected cells from either surface...

In obesity, gut microbiota LPS may translocate into the blood stream and then contribute to adipose tissue inflammation and oxidative stress, leading to insulin resistance. A causal link between periodontal infection, obesity and type 2 diabetes has also been suggested. We evaluated the ability of polyphenols from Antirhea borbonica medicinal plant to improve the inflammatory and redox status of 3T3-L1 adipocytes exposed to LPS of Porphyromonas gingivalis periodontopathogen or Escherichia coli enterobacteria...

Culture remains the gold standard for diagnosis of blood stream infections (BSI), but its clinical utility is limited by slow turnaround times. Here we describe a method for rapid quantitative detection of bacterial DNA directly extracted from whole blood using a multiplexed tandem real-time PCR (MT-PCR) assay targeting Staphylococcus, Streptococcus, Pseudomonas, Enterococcus and Enterobacteriaceae 16S rDNA genes. Results were available less than 3.5 hours after blood collection with all five bacterial targets having limits of detection between 10(1) and 10(3) CFU/mL...

BACKGROUND: Living donor liver transplantation is now an established technique for treating children with end-stage liver disease. Few data exist about liver transplantation for exclusively young infants, especially infants of <3 months of age. We report our single-center experience with 12 cases in which living donor liver transplantation (LT) was performed during the first 3 months of life and compare the results with those of older infants who underwent LT. All of the patients were treated at the National Center of Child Health and Development, Tokyo, Japan...

Biofilm forming capacity of yeasts colonizing the intravenous devices is considered a key factor involved in the pathogenesis of Candida catheter-related bloodstream infections (CCRBSI). The biofilm production of strains of Candida spp. isolated both from the CVC and from the blood of patients with CCRBSI was compared to that of strains isolated from patients not having CCRBSI. Results, expressed in terms of Biofilm Index (BI), revealed that biofilm-producing strains were isolated in the CCRBSI group with a frequency significantly higher than in the non-CCRBSI group (χ(2) = 4...
