Filter by:Rationale: Survival rates of teeth with laminate veneers were reported to have more marginal caries and discoloration when existing restorations are present. However in these studies no conditioning of the existing restorations was performed. Objective: This study evaluate the survival rate of ceramic laminate veneers bonded to teeth with and without existing composite restorations Study design: Prospectief Cohort research Study population: the participants received laminate veneers and older then 18 years. Intervention (if applicable): The participants received laminate veneers in the past. No intervention. Main study parameters/endpoints: Survival and success of laminate veneers with existing restorations: Survival (no loss of laminate veneer during follow up time), Success was measured using USPHS health criteria. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The participants are asked to come for a check-up of their restorations, the investigators will evaluate the laminate veneers by sight and take some light photo's and a patient questionnaire will be given.
Cardiac magnetic resonance imaging has been established as a promising three dimensional imaging modality with the ability to assess cardiac morphology, ventricular function, perfusion, viability and imaging characteristics of the surrounding vasculature without ionizing radiation. The accurate treatment of patients with cardiac disorders has created the need for accurate and reproducible measurements of cardiac chamber volumes and function. Cardiac magnetic resonance has the ability to provide this information as well as assess edema, perfusion, viability and vascular anatomy.
There is evidence that the current dosing recommendations of ceftazidime in hemodialysis patients may not reach the critical pharmacokinetic/pharmacodynamics thresholds associated with maximal efficacy. The primary objective is to assess whether the standard doses of ceftazidime (1 or 2 g) administered at the end of the dialysis session (intermittent dialysis) allow to obtain a trough level equal or superior to 8 mg/L if the causative organism is not identified or 1 x the MIC if it is identified and its in vitro susceptibility to ceftazidime established. The secondary objectives will be (i) to assess whether a trough level equal or superior to 32 mg/L (if the causative organism is not identified) and 4 x its MIC (if identified and its in vitro susceptibility established) can be obtained; (ii) whether the criteria mentioned above also apply to the free fractions of ceftazidime; (iii) to assess whether reaching the desired free and total trough concentrations impacts the clinical outcome of the patient; (iv) to assess whether the main hemodialysis parameters impact on ceftazidime total and free serum concentrations; (v) to assess the impact of patient's residual renal function on the ceftazidime serum free and total concentrations; (vi) to assess the impact of potential drug-drug interactions on ceftazidime serum free and total concentrations; (vii) to assess how the MIC of the causative organism (if known) affects the expected effectiveness of ceftazidime. The study will be prospective and monocentric. Drug assay will be made High Performance Liquid Chromatography (HPLC) and UV photometric detection (confirmed by tandem mass spectrometry detection[HPLC-MS-MS]). Free concentration will be measured after separation by membrane sieving. The expected number of enrolled patients will be 20 (arbitrarily chosen but compatible with previous studies and the possibilities of the Institution in which the study will be performed. The standard dose of ceftazidime will be (i) a loading dose of 2 g followed by a maintenance dose of 1 g (the dose may be modified by the clinician in charge if deemed necessary and recorded accordingly). The data obtained will be used for pharmacokinetic modelling and population pharmacokinetics, followed by Monte-Carlo simulations to obtain population-wide predictions and to draw conclusions that could be applicable to a larger population.
To evaluate the efficacy and safety of vitreoretinal surgery combined with anti-VEGF therapy in the replacement of intraoperative PRP in PDR therapy.
Using a single blind, randomized controlled design to study the additional therapeutic effects of cognitive training on traditional rehabilitation programs for children with attention deficit hyperactivity disorder and developmental delays.
VITAL is an open-label, Phase 3 study of one-time surgical application of at least 35 EB-101 grafts for the treatment of eligible, chronic open wound sites in up to 15 RDEB patients. Patient wounds will be randomized to receive grafting or remain untreated (control). Up to 6 wound sites for EB 101 grafting and at least 1 untreated control wound site will be performed for each patient.
Glioma is the most common primary cancer of the central nervous system, and around 50% of patients present with the most aggressive form of the disease, glioblastoma. Conventional therapies, including surgery, radiotherapy, and pharmacotherapy (typically chemotherapy with temozolomide), have not resulted in major improvements in the survival outcomes with only a median survival of around 15 months.The main reason may be related to the highly immunosuppressive tumor microenvironment. In recent years, the microbiome has emerged as a key regulator of not only systemic immune regulation but brain circuitry, neuro-physiology and microglia development. We hypothesized that there is a link between the gut microbiota and the GBM development and evolution through the immune regulation cells (microglia and tumor related macrophagocyte) in the blood circulation to impact the prognosis( PFS and MST) of GBM patients.
Single blinded Randomised Controlled trial comparing standard therapy to the intervention of up to 1 hour of physiotherapist-prescribed resistive training exercises administered via a telerehabilitation device per day in addition to standard therapy for a total of 10 sessions over a 2 week period. Total recruitment: 60 patients.
All participants will underwent imaging using the OCTA system (Zeiss) with the anterior segment optical adaptor lens. The main outcomes are iris blood flow density and vascular density.
This is a Phase III, randomized, double-blind, multicenter, non-inferiority study to evaluate the efficacy, safety, and tolerability of FEP-TAZ vs. meropenem in the treatment of hospitalized adults with cUTI or AP.
