Filter by:Patients with acute decompensation of cirrhosis, or acute on chronic liver failure often present with malnutrition, and due to the in-hospital stay, their nutritional intake can vary widely, with several periods of fasting, and sometimes insufficient nutritional support. Therefore patients are prone to develop malnutrition or, the already present malnutrition worsens its status. Our aim is to evaluate the daily changes in nutritional status in patients with acute decompensation of cirrhosis and evaluate the changes in plasma and serum biomarkers.
The purpose of this study is to assess the effectiveness and costs associated with the intravesical administration of combined hyaluronic acid (HA) and chondroitin sulphate (CS) compared to the current standard management of recurrent urinary tract infections in adult women diagnosed with recurrent urinary tract infections (RUTI).
Premature infants (born before 34 wk) are routinely vaccinated against RSV but vaccination rate against influenza are low in spite of national programs. Study goal is to evaluate the effectiveness of short intervention during RSV prophylaxis visit, planned to educate parents about the importance of influenza vaccination.
Poor Ecuadorian older people suffer from chronic dietary deficiencies of zinc, iron, copper, vitamins C, B6, B12, D, and folic acid. The investigators have previously shown that these deficiencies are associated with impaired immune function and increased incidence of respiratory infections (RI). The hypothesis is that correction of these specific nutrient deficiencies will improve immune response and thereby enhance resistance to respiratory infections. To test this hypothesis this study will evaluate the effect of supplementation with specific vitamins and minerals found to be deficient in poor elderly Ecuadorians on markers of immune function and the incidence of RI. A randomized, double-blind, placebo-controlled trial in 320 older people (≥65 y)will be carried out in Quito, Ecuador. Participants will receive multivitamin and mineral supplements or placebo tablets daily for 12 months. Nutrients will be provided at US Recommended Daily Allowance (RDA) levels, except for vitamin C and zinc doses, which will be 5 times and 1.25 times higher than the RDA, respectively. Incidence of respiratory infections (the primary outcome) will be assessed weekly by field nurses and physicians from the study team. Secondary outcomes include delayed-type hypersensitivity (DTH) skin test, cathelicidin production by mucosa respiratory cells, and serum C-reactive protein (CRP) as measures of immune function. Blood micronutrient levels and haemoglobin status will be collected as measures of adherence to the trial regimen. Incidence rate of RI and rate ratio (RR) will be calculated to quantify the effect of the intervention on the incidence of respiratory infection. This will be the first trial of its kind conducted specifically in a population of older people known to have poor micronutrient status. The findings of the study may be important for similar populations in other low- and middle-income countries.
Diagnosis of late-onset sepsis is difficult in the absence of specific clinical signs and biological markers in the infection initial phase .The aim of this study is to determine the performance of a new infection marker : Neutrophil CD64 for early diagnosis in nosocomial infection (NI) in preterm newborns. METHODS : - Monocentric prospective study including preterm newborn infants (<37 weeks of gestationnal age ) with clinical suspicion of nosocomial infection in a neonatal intensice care unit (Neonatal intensive care unit of Montpellier, France). - Patients will be enrolled in the study after informed consents. Rapid and automated CD64 measurment will be realized during the conventional blood sample including C-Reactive Protein (CRP), Procalcitonin (PCT) and blood culture. - Broad-spectrum antibiotic therapy can be started on the advice of clinician and blinded the result of CD64. Patients will be then classed in three groups using CDC criteria (center for disease control) : 1-no infection, 2-infection, 3-possible infection during the multidisciplinary staff. Specificity, sensitivity, negative and positive value of CD64 will be calculated and the performances of CRP, PCT and CD64 will be compared. 153 patients are needed in the study enrolled during a period of 12 months. PERSPECTIVES Neutrophil CD64 monitoring might be help clinicians to manage nosocomial infections in neonates.CD64 allow to integrate in a decision algorithm with the determination of the best cut-off value to faster processing nosocomial infections and could help to reduce unnecessary antibioc therapy. A rapid technique for determination of CD64 should be readily available in our unit.
Serum samples will be corrected twice from the same youth subjects with one year interval. Seroincidence of pertussis will be estimated by the elevation of Ig-G-PT in paired sera from an identical individual. The relationship between the incidence and the demographic data or medical history of the subjects will be discussed.
The study will investigate whether the placement of silver plated dressings beginning in the OR will improve wound healing in patients undergoing cesarean delivery compared to traditional Telfa pads. This study will also explore the presumed improvement in scar integrity when silver plated dressings are used compared to Telfa pads. The study will examine post-operative pain by review of anesthesia and analgesic use during hospitalization and scar-related pain scores at the post-operative visits. The study will compare the percentage of patients who develop a surgical site infection after application of silver plated dressings versus standard Telfa dressings. Investigators will also assess the cosmetic appearance of the cesarean section scar at the patient's one week and 6 wekk post-operative visits.
Microbial infection of the cornea, also known as microbial keratitis, causes severe corneal inflammation that could result in permanent visual loss. Contact lens wear is the strongest risk factor related to microbial keratitis in developed countries. The most commonly isolated pathogen of contact lens associated microbial keratitis (CLMK) is Pseudomonas aeruginosa, which accounts for over one third of the cases. Among the various virulence factors involved in the pathogenesis of pseudomonal keratitis, a secretion system known as type three secretion system (T3SS) secretes toxins that damage the host cells. ExoS is a bifunctional exotoxin with GTPase-activating protein (GAP) activity and ADP ribosyl transferase (ADPRT) activity. It results in an invasive phenotype of P. aeruginosa causing a relatively slower host cell death with intracellular invasion and possibly proliferation of bacterium. In contrast, ExoU expressing strains carries a cytotoxic phenotype that causes rapid host cell lysis due to its phospholipase activity. Previously, cytotoxic strains were reported to be more commonly found in patients with pseudomonal keratitis and were highly correlated with multidrug resistance. In order to understand the pathogenesis of CLMK, especially pseudomonal related CLMK, we proposed to recruit 180 volunteers who will wear different contact lens materials. We then collect the used contact lens and analyze 1) the microbiota on the used contact lens; 2) the bacterial-contact lens adhesion of wild strains, pscC mutant strains (T3SS needle-comples mutant), cytotoxic strain, and invasive strain P. aeruginosa; 3) the effect of shearing forces on bacterial-contact lens adhesion; 4) the bacteriocidal effect of multipurpose solution on different strains of P. aeruginosa.
The wound infection rate in the groin after vascular surgery has been denoted to be high since the wound surveillance register started in 2005. The current wound infection rate based on a validation study was 22.9% (24/105 patients with groin incision(s) between 1 March to 30 June in 2012). This randomized controlled trial aims to evaluate if negative pressure wound therapy on closed inguinal incisions (INPWT) after vascular surgical procedures can reduce the risk for surgical site infections and other wound complications.
Whether non-bismuth quadruple therapy (concomitant therapy) is more effective than bismuth quadruple therapy or triple therapy for 14 days remains unknown. Therefore, we aim to compare the eradication rates and long term re-infection rates of quadruple therapy for 10 days versus non-bismuth quadruple therapy for 10 days vs. triple therapy for 14 days. Methods: This will be a multi-center, open labeled, randomized control trial Patients: H. pylori infected patients who have willingness to receive eradication therapy Testing for H. pylori infection Before First Line Ttreatment (1)Any two positive of rapid urease test, histology, serology and culture or a positive UBT will be considered as H. pylori infected After First Line Treatment: C13-Urea breath test will be used to assess the existence of H. pylori 6-8 weeks after first line therapy. Long term reinfection: C13- Urea breath test will be used to assess the recurrence of H. pylori 1 year after eradication therapy
