Filter by:Dual-focus with narrow-band imaging (DF-NBI) is a novel technique to improve the quality of images of the irregular mucosal structures and microvessels of gastric neoplasms. The investigators compare this technique with conventional white light (WL) endoscopy to predict Helicobacter pylori infection.
Cesarean deliveries are the most common surgical procedure performed in the United States. A significant decrease in cesarean delivery associated maternal morbidity has been achieved with preoperative prophylactic single-dose cephalosporin, widely used before skin incision. Also, on laboring patients and/or with rupture of membranes, several studies suggest that adding azithromycin to standard cephalosporin prophylaxis is cost-effective and reduces overall rates of endometritis, wound infection, readmission, use of antibiotics and serious maternal events. Azithromycin has effective coverage against Ureaplasma, associated with increased rates of endometritis. Although two-drug regimen has been suggested for laboring and/or patients that undergo cesarean delivery, no studies have investigated the potential benefits of two-drug regimen in non-laboring patients.
The investigators aim to study the population pharmacokinetics of children receiving the anti-infective drugs for treatment of infectious disease in central nervous system.
Background: Poor personal hygiene and inadequate sanitation practices among young children in Low Middle Income Countries such as Pakistan can lead to critical, life-threatening illnesses such as respiratory infections, diarrheal disease, malnutrition and developmental delays. An intervention for personal/environmental hygiene practices for primary schoolchildren will be implemented at schools in urban squatter settlements of Karachi, Pakistan, aiming to improve the hygiene knowledge and practices (K&P) amongst primary schoolchildren and their mothers (participants), while identifying facilitating and impeding factors in the adoption of hygiene practices for children. Methods: The study will be built on quasi-experimental design with mixed methods data collection approaches. To assess primary grade children and their mothers' hygiene-status, K&P survey will be held in the pre-intervention phase. This phase also includes qualitative exploration of mothers' and teachers' perceptions about children's hygiene literacy, factors facilitating and impeding the adoption of the same among school children, for which in-depth guides and focus group discussion tools will be used with teachers and mothers respectively. School physical environmental assessment will be carried out pre-post intervention. This will be followed by multi-component intervention phase with behavior change strategies to improve children's and mothers' hygiene K&P. The post-intervention phase will assess the intervention effectiveness in terms of enhancing hygiene K&P among schoolchildren and mothers, alongside exploration of mothers and teachers' insights into whether or not the intervention has brought changes in improving hygiene practices among children. Results: Paired T-test will be done pre-post intervention to measure the differences in knowledge and practice scores between mothers' hygiene literacy and practices with their child's knowledge and practices. Similar test will also be run to assess the differences in children' hygiene knowledge and practice scores pre and post intervention. Thematic analysis will be used for qualitative data. Discussion: Multi-component intervention aimed at improving personal and environmental hygiene among primary school children offers an opportunity to design and test various behavioral change strategies at school and home setting. The study findings will be significant in assessing the intervention effectiveness in improving children's overall hygiene.
Quasi-experimental intervention multicenter trial of patients treated with new antibiotics (before-after study). The study will be carried out in 14 hospitals of the Andalusian Public Health System with representation from all the provinces and has been designed in two phases: 1. A first phase in which an observational study of historical preintervention cohorts of patients who have received either empirical or targeted treatment with ceftaroline, tedizolid, dalbavancin, ceftazidime-avibactam, ceftolozane-tazobactam and isavuconazole from January 2016 to December 2019 will be developed. Case detection will be carried out by locating the antimicrobial prescriptions in the electronic prescribing systems and / or pharmaceutical management systems of each hospital. A set of epidemiological, clinical, microbiological and prognostic variables will be completed in each case. 2. A second phase or intervention period that will be applied to the cohort of patients treated with new antibiotics (intervention cohort) from January 2020 to June 2021. A quasi-experimental intervention study will be carried out through the development of a Program for Optimizing the use of Antibiotics (PROA) in Spanish, Antimicrobial Stewardship Program (ASP) in English, in the participating hospitals. It will consist in the development of a consensus document on the use of new antibiotics following a Delphi methodology, dissemination of the consensus document / guide among the participating hospitals and audit on the prescription of new antimicrobials after the implementation of the guide based on providing non-imposition advice and positive reinforcement to the prescriber. The recommendations will be consigned in a structured form, which will allow to evaluate the degree of follow-up of the recommendations. The audit will be performed on day 0-1 of the prescription. 3. Cohort of bacteremia due to multiresistant microorganisms ("safety" cohort): In order to evaluate the safety of the use of new antimicrobials against therapeutic alternatives in syndromes where they are potentially a preferred option and parallel to the two phases, episodes for bacteremia by carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa, carbapenem-resistant enterobacteria, vancomycin-resistant Enterococcus faecium and methicillin-resistant Staphylococcus aureus occurred in participating hospitals from 2017 to 2021 will be collected.
The role of miRNAs in HIV disease is yet to be completely defined. Host miRNAs target certain HIV genes, thus can affect HIV replication and participate in viral control. miRNAs can also block HIV production through disruption of Gag assembly on cell membranes. miRNA expression can characterize HIV disease phenotype, as has been shown in HIV elite controllers who have a well-defined miRNA expression profile. However, the studies of miRNA in acute infection and co-infections like tuberculosis are lacking. The investigators showed that during immune reconstitution syndrome (IRIS) in HIV/TB coinfected patients, innate immune response play a role as through NK cell degranulation, therefore testing for this could be used as a predictive marker of IRIS. One of the limitations of miRNA detection is the technique, which is time-consuming, and needs laboratories that are specialized and equipped for molecular biology techniques. In contrast, flow cytometry has been developed in routine labs and has well-standardized techniques. For the routine detection of miRNA, flow cytometry could be the best way to perform high throughput screening for clinical applications. Flow cytometry is a simple and effective way to evaluate miRNAs expression. In this project the investigators propose to evaluate, using flow cytometry, whether circulating miRNA pattern might be applicable as potential biomarkers in prediction and prognosis of IRIS in HIV/TB co-infected patients. The investigators propose to study the miRNA expression profile in a cohort of patients with a HIV infection and Tuberculosis and correlate it with their clinical evolution. As controls, the investigators propose to analyze expression of miRNAs in healthy controls as well as TB and HIV mono-infected patients. AIMS OF THE PROPOSAL 1. Identify miRNA expression profile as potential novel predictive and prognostic biomarkers for IRIS. 2. Identify the miRNA expression profile in HIV patients, in TB patients and in HIV/TB co-infected patients.
Up to 1 in 5 women in Africa who deliver their baby by cesarean section get a wound infection. Surgical site infections (SSIs) are largely preventable, but they represent a considerable burden for health-care systems, particularly in low-income and middle-income countries. The prevention of these infections is complex and requires the integration of a range of preventive measures before, during, and after surgery. The aim of the proposed project is to determine the risk factors of Surgical Site Infection post-Cesarean Section in women admitted to Princess Christian Maternity Hospital (PCMH) in Freetown, Sierra Leone. Secondary aims are to determine the incidence of SSI and the predictors of a negative outcome in women with post-CS SSI.
The aim of this study was to compare the frequency of occurrence of digestive carrying of 3rd generation cephalosporin-resistant enterobacteriaceae (EB C3G-R), acquired during hospitalization in one of the participating departments, between patients treated with ceftriaxone and patients treated with cefotaxime
This study aim to compare the cost-effectiveness and safety between centrally and peripherally inserted central venous catheters in neurosurgical intensive care unit patients.
Postoperative infections are a common complication. A relationship between perioperative severe hyperglycemia and postoperative infections has been found in patients undergoing craniotomy. The aim of this study is to evaluate the epidemiology of intraoperative severe hyperglycemia (BGC >180 mg/dL; 10 mmol/L) and postoperative infections (wound, urinary and prosthetic joint infection) and to investigate if severe intraoperative hyperglycemia is associated with an higher risk of early postoperative (within the 7th postoperative days) infections (wound, urinary and prosthetic joint infection).
