Filter by:The overall aim of the project is to fill an important knowledge gap on the ecological effects of selected antibiotics. The results will be used to guide treatment decisions for common infections to as much as possible reduce the negative impact on the intestinal microbiota and consequently the risks of side effect and resistance development during therapy. Specific aims for this study are to determine (1) the composition of intestinal microbiota and prevalence of resistant bacteria and resistance genes prior to and up to 1 year after antibiotic treatment, and (2) the relative effects on the microbiota after treatment with three antibiotics used for lower respiratory tract infections; phenoximethylpenicillin, amoxicillin and amoxicillin-clavulanic acid, or no treatment (control). A total of 120 healthy volunteers will be recruited to the study. They are randomised to 5 days' treatment with phenoximethylpenicillin, amoxicillin or amoxicillin-clavulanic acid, or to no antibiotic treatment. Subjects submit faecal samples at eight different time-points; at the start of the study (before treatment), immediately, one week and 1, 3, 6, 12 and 24 months after completion of the treatment. The samples will be delivered to Scilifelab for metagenomic sequencing to detect antibiotic resistant genes and analysis of the intestinal microbiota and to the Microbiology ward for analysis with phenotypic methods (culturomics) to detect resistant genes and resistant bacteria.
The emerging crisis of multidrug-resistant bacteria is accelerated by a massive overuse and misuse of antibiotics. It has been estimated that 50% of antibiotic prescriptions are inappropriate. Antibiotic interventions to improve prescribing patterns have been successfully implemented in primary care in Sweden and other countries. However, much of the last-resort antibiotics are used in hospitals in which decisions on therapy for bacterial infections are more complex. In this project we will explore the appropriateness of antibiotic prescribing in a hospital setting and measures to improve the quality of antimicrobial therapy. Antimicrobial stewardship interventions will be conducted at selected hospital departments using prospective audit and feedback in a multifaceted and cross-disciplinary approach. The intervention effects on antibiotic consumption, appropriateness of prescriptions, patient outcome and emergence of resistance will be evaluated, and a financial cost-effectiveness analysis will be performed.
The aim of this cohort is to identify environmental, lifestyle and genetic factors that modify the human intestinal microbiota development during the first years of life, and to identify early microbiota features that associate to child health and well-being with focus on the development of allergic diseases and overweight.
Direct constitution of collections from various samples taken on a prospective cohort of healthy volunteers, to prepare human biological samples of known characteristics (biochemical and serological in particular) and quality controlled.
Antibiotic use may be associated with effects on the perception of smell and taste. These effects are poorly known. The mechanisms can be very diverse, and the effect can be very variable depending on the type of antibiotic used, the dose, and the duration. The aim of this study is to analyze the perception of the taste and olfactory capacities of patients, during an antibiotic treatment.
Pneumonia in Pakistan continues to be the leading killer of children under five. Although various national and provincial programs have tried to tackle this but they have not been able to achieve the desired outcomes. Additionally, there has been limited in depth evaluation of the practices of pneumonia management at various levels of the community. The investigators, therefore, aim to establish an understanding of pneumonia case management at three levels of healthcare - community, first level care facility and practitioner level. This will be conducted through observations of pneumonia case managements practices of healthcare providers at these three levels across the country by simulated patients. Observation checklists will be developed incorporating settings and behaviors. Observation sites will be randomly selected with 32 observations made in each province. The results of this study will yield the ground reality of pneumonia case management in Pakistan. Based on the results of this study, strategies can be devised to improve case management within the community with models of regular monitoring and supervision.
iSpecimen aims to create a clinical partner network of hospitals, laboratories, academic institutions, and other healthcare organizations ("institutions") capable of providing researchers and educators ("researchers") with annotated biospecimens for use in biomarker discovery and validation; diagnostic test and instrumentation development and validation; therapeutics development; other medical research including the impact that various specimen collection and handling methods and conditions have on research results; and in education such as researcher or physician training (collectively "research").
Consensual antibiotic protocols have been developed and validated locally by infectious disease specialists, internists and emergency physicians, in order to encourage their compliance. A preliminary study was conducted from June 2015 to February 2016, including 622 patients admitted to the emergency department for infectious syndrome such as / - Pneumoniae - Urinary tract infection - Cellulitis - Meningitis - Malaria - Febrile neutropenia - Febrile acute diarrhea - Fever back to the tropics - Angina - sexually transmitted infection This prospective study will observe and analyze the adherence of prescribers to these protocols. With description of patients who benefited or not the antibiotic protocol, according to a syndromic approach and analysis of the causes of non-adherence to the protocols. In order to limit the length of stay and reduce the cost of hospitalization..
This is three part study that will, in part one assess the safety, tolerability, and PK of a single dose of CRV431 in healthy volunteers. The second part of the study will be a single dose drug-drug interaction study in healthy volunteers with CRV431 co-treated with TDF. The third part of the study will assess the safety, tolerability, PK, and preliminary signal for antiviral efficacy and identification of clinically-relevant biomarkers of CRV431 with TDF in stable HBV patients.
The goal of this study is to assess the utility of a data visualization tool for providers' understanding patients' past microbiological culture sensitivities. Providers that are ordering antibiotics for patients with previous culture data in the medical record will be asked to answer questions regarding past sensitivity results. They will be randomized to either using the visualization tool before answering the questions or using the standard medical record tools. They will then be surveyed about their decision-making, knowledge, and the usefulness of the tool.
