Filter by:This research aims to study the properties of metallic nanoparticles"MNPs" (silver nanoparticles "AgNps" and copper nanoparticles "CuNps") on the 2 most common nosocomial bacteria which are highly resistant to antibiotics including Staphylococcus aureus and Pseudomonas aeruginosa, to evaluate the growth inhibiting properties of MNPs on all bacterial isolates, to evaluate the biofilm inhibitory effect on biofilm forming bacterial isolates and the synergistic effect of these MNPs in combination with antibiotics on the antibiotic resistant isolates.
Nonfermenting Gram-Negative Bacilli (NFGNB) are aerobic, non-motile, non-lactose fermenting, oxidase-negative, catalase-positive coccobacilli that pose a serious threat to critically ill patients. Primarily Pseudomonas aeruginosa (PA) and Acinetobacter baumannii (AB), are NFGNB which are potential multi-drug resistant (MDR) pathogens that are related to ventilator-associated pneumonia (VAP). In Nonfermenting Gram-Negative Bacilli (NFGNB) infections, which are potential multi-drug resistant (MDR) pathogens, pathogenesis is determined not only by bacterial virulence factors but more importantly by the interaction between bacteria and the host immune system. Thanks to their direct immunomodulatory properties, lipoproteins and lipids bind and neutralise toxic bacterial substances. During the acute phase response and inflammation, HDL presents significant structural and functional changes. This study was planned to evaluate the relationship between the changes of the serum lipid metabolism and other inflammation markers with the antimicrobial resistance status and the results in NFGNB VAP patients. Also, we aimed to investigate whether there is a difference in the clinical characteristics of the patients depending on the resistance profile of NFGNB.
The study is a first step in establishing the safety and efficacy of the CytaCoat technology when applied to a medical device such as a nasal prong and the clinical data generated will serve as a basis for continuous studies in clinically significant settings such as the neonatal care units.
This 4-year cluster randomized controlled trial aims to determine whether implementation of Evidence-based Practice for Improving Quality (EPIQ) method can reduce hospital-acquired infection in Chinese Neonatal Intensive Care Units (NICUs).
Healthcare-acquired infections (HAI) cause substantial patient morbidity and mortality. Commonly touched items in the patient care environment harbor microorganisms that may contribute to HAI risk. The purpose of this study is to assess whether placement of copper-alloy surfaced objects in a pediatric intensive care unit (PICU) reduce risk of HAI in comparison with non-copper surfaced objects.
Nosocomial infection with antibiotic-resistant strains is a major threat to critical care medicine. Selective decontamination of the digestive tract (SDD) is one of the strategies to reduce ventilator associated pneumonia and sepsis in critically ill patients. Lactoferrin (LF) is a natural multifunctional protein with antimicrobial, anti-tumor, antioxidant, and immunomodulatory effects. It has been shown to inhibit the growth of a number of pathogenic bacteria including antibiotic-resistant strains, fungi and even viruses in both in vitro and in vivo studies. In a recent study, the investigators performed pathogen challenges of the digestive tract of a transgenic milk-fed animal model. The results showed that recombinant LF has broad spectrum antimicrobial activity in the digestive tract and protects the mucosa of the small intestine from injury, implying that LF can be used as an effective selective decontaminant of the digestive tract. This study is a prospective, randomized, double-blind, placebo- controlled clinical trial examining whether oral supplementation with bLF can reduce nosocomial infection, sepsis and even mortality in patients with prolonged mechanical ventilation (MV). Patients with MV for more than 21 days and no signs of infection on admission to our Respiratory Care Center (RCC) will be enrolled. They will be randomized to receive either bovine LF (bLF, 10 mg/kg/day) or placebo for 6 weeks by center. The primary objective is to evaluate the effectiveness of bLF in the prevention of nosocomial infection. Secondary objectives are assessment of incidence of nosocomial infection, mortality, weaning rate from MV and change of the immune system. The investigators hypothesize that bLF may 1) prevent nosocomial infection; 2) reduce mortality; 3)increase weaning rate from MV; 4)increase immunity in patients with prolonged MV.
Most literature on ICU infections and the resistant patterns comes from the western literature. This data may not truly reflect the incidence, epidemiology and resistance patterns in developing countries such as India. However, empiric antibiotic therapy is generally initiated using western guidelines. This can potentially lead to inadequate, inappropriate and ineffective empiric antibiotic therapy for ICU infections in the Indian setting. Hence in this multi-center observational study, we seek to: 1. To determine the incidence of ICU-related infections (VAP, CAUTI and CRBSI) in India 2. To explore the microbiology, resistance and treatment patterns of these infections
Severe bacterial infections are associated with mortality of about 30%. Patients with moderate to severe bacterial infections given early and appropriate empirical antibiotic treatment are at a lesser risk for a fatal outcome, with odds ratios ranging from 1.6 to 6.9. However only about 2/3 of patients worldwide are given early and appropriate empirical antibiotic treatment. About 40% of patients treated with antibiotics are given superfluous treatment. TREAT is a computerized decision support system for antibiotic treatment in inpatients with common bacterial infections. TREAT is based on a state of the art stochastic model of the domain (a causal probabilistic network) and uses a cost benefit model for antibiotic treatment, including costs assigned to future resistance. It was tested in a randomized controlled trial in 3 countries and shown to improve the percentage of appropriate empirical antibiotic treatment while at the same time reduce hospital stay and the use of broad-spectrum antibiotics. The main limitation of TREAT is inherent in the limited information available within hours of presentation. A second attractive approach to improve antibiotic treatment is to use techniques that do not depend on cultures, and thus shorten the time to identification of the pathogen to a few hours only. The LightCycler® SeptiFast test from Roche performs in vitro nucleic acid amplification test for pathogens causing bloodstream infections. The purpose of the clinical trial is to show that the combined system TREAT/PCR assays will improve the outcome of inpatients with moderate to severe bacterial infections, while at the same time reducing the use of broad-spectrum antibiotics, with no or little additional costs. A secondary objective will be to assess the sensitivity and specificity of whole blood PCR, using TREAT as the reference standard.
This study will evaluate the safety, toxicity and efficacy of talactoferrin in reducing the incidence of all nosocomial infections in prematurely-born infants.
The Oncoped 2006 study implements a multicenter prospective surveillance module for nosocomial infections in pediatric cancer patients.
