Filter by:In this prospective observational study, a quantitative and qualitative analysis of antibiotic prescriptions for presumed respiratory tract (super)infection in patients hospitalized on COVID-19 wards will be made. Drivers of antibiotic prescription for presumed respiratory tract infection in patients suspected of being infected with COVID-19 or with definite COVID-19 infections will be identified.
BK virus infection is one of the causes of renal allograft loss in the current era. Reduction of immunsuppression is the only intervention that prooved to be effective in treating of BK virus in kidney transplant recipient. However, there are evidences from retrospective and prospective studies showed that leflunomide and mTOR inhibitor such as everolimus or sirolimus have positive outcomes in treatment of BK virus in kidney tranplant recipient. The investigators conduct the RCT to compare the efficacy of leflunomide and mTOR inhibitor everolimus, in treatment of BK virus infected patients who do not respond to immunosuppression reduction.
This is a multi- centre trial of children with bone and joint infections (BJIs) at eight major paediatric hospitals in Australia and New Zealand. The primary objective is to establish if in children with acute, uncomplicated BJIs, entirely oral antibiotic treatment is not inferior to initial intravenous (IV) treatment for 1 to 7 days followed by an oral antibiotic course in achieving full recovery 3 months after presentation. Children will be randomly allocated to the 'entirely oral antibiotic' group or the 'standard treatment' group.
Currently the diagnosis of OA is based on radiographs and clinical findings, which is limited to detecting late-stage disease. There is a pressing, unmet clinical need for robust assessment of early changes in cartilage health. Towards this goal, extensive efforts are ongoing to develop quantitative MRI for cartilage matrix analysis. MR T1ρ and T2 relaxation times have shown to be promising imaging biomarkers for early cartilage degeneration and prediction of disease progression. However, many challenges remain to clinically applying these techniques, including lack of standardized acquisition and quantification methods, and long acquisition times. The study aims to develop novel, fast and reproducible MR T1ρ and T2 relaxation time imaging methods on MR systems from multiple vendors and establish a platform for standardization and cross validation of these measures as a tool for clinical trials using such techniques. Following method validation, patients at risk for osteoarthritis will be tested.
Carbapenem-resistant Enterobacteriaceae (CRE) are increasingly identified in children in China. Pediatric intensive care unit (PICU) is the high-risk area. However, data on the epidemiology of CRE in hospitalized children in PICU are limited. The objectives of this study are to characterize the risk factors for colonization or infection with CRE and describe the microbiologic characteristics of pediatric CRE isolates. The investigators will perform a single retrospective study from January 2018 to December 2019 at PICU of Children's Hospital of Fudan University .
SARS-CoV-2 infection seems to induce in most critical cases an excessive and aberrant hyper-inflammatory host immune response that is associated with a so-called "cytokine storm", moreover pro-thrombotic derangements of haemostatic system is another common finding in most severe forms of COVID19 infections, which may be explained by the activation of coagulative cascade primed by inflammatory stimuli, in line with what is observed in many other forms of sepsis. Targeting inflammatory responses exploiting steroids' anti-inflammatory activity along with thrombosis prevention may be a promising therapeutic option to improve patients' outcome. Despite the biological plausibility, no good evidence is available on the efficacy and safety of heparin on sepsis patients, and many issues have to be addressed, regarding the proper timing, dosages and administration schedules of anticoagulant drugs. The primary objective is to assess the hypothesis that an adjunctive therapy with steroids and unfractionated heparin (UFH) or with steroids and low molecular weight heparin (LMWH) are more effective in reducing any-cause mortality in critically-ill patients with pneumonia from COVID- 19 infection compared to low molecular weight heparin (LMWH) alone. Mortality will be measured at 28 days. The study is designed as a multicenter, national, interventional, randomized, investigator sponsored, three arms study. Patients, who satisfy all inclusion criteria and no exclusion criteria, will be randomly assigned in a ratio 1:1:1 to one of the three treatment groups: LMWH group, LMWH+steroids or UFH+steroid group. A possible result showing the efficacy of the composite treatment in reducing the mortality rate among critically ill patients with pneumonia from COVID-19 infection will lead to a revision of the current clinical approach to this disease.
This prospective study will investigate the concentrations of tacrolimus metabolites (M-I and M-III) over the four first years post-transplantation. A differential metabolism might result in different metabolites' concentration and explain a kidney survival difference between "high rate metabolism" (defined as a concentration/dose ratio, C/D ratio, lower than 1.04 µg/l/mg) and other patients. The primary endpoint is therefore to compare tacrolimus metabolites' concentrations with respect to the group, either < or >= 1.04 µg/l/mg, in order to detect differences in tacrolimus metabolization between these groups.
Infectious uveitis is a very important blinding disease. Some people who have been diagnosed with idiopathic uveitis may also have the activity of pathogens in the eye. However, due to the limitation of the amount of ocular samples, it is difficult to make a rapid and effective diagnosis of infection.Current study is to explore the infective cause of uveitis in China by using a broad diagnostic approach of detection.
The McMaster Multi-Regional Hospital Coronavirus Registry (COREG) is a platform that is collecting detailed case data on laboratory confirmed COVID-19 hospital inpatients and outpatients. The COREG platform will provide rapid high-quality evidence to improve the prevention and clinical management of COVID-19 for older adults in Canada, and internationally. The COREG platform will also provide researchers and partners with complete regional level clinical data on COVID-19 cases to inform rapid decision-making and projections, sub-studies, extensions, and linkage for all affected populations.
This trial investigates whether a one-month course of preventative (prophylactic) antibiotics helps to reduce urinary tract infections after robot-assisted surgery to remove all of the bladder as well as nearby tissues and organs (radical cystectomy). Urinary tract infections are a common occurrence after robot-assisted radical cystectomy. Antibiotics such as trimethoprim-sulfamethoxazole or nitrofurantoin may prevent or control infections in patients with urinary tract infection and may help improve their response to radical cystectomy. Information gained from this study may help researchers to predict patient complications and identify better ways to manage these complications.
