Filter by:The objective of this trial is to determine whether an opioid-free general anesthetic (OFA) technique utilizing ketamine, dexmedetomidine, lidocaine, and gabapentin can help reduce postoperative respiratory depression in the post-anesthesia care unit and ward in children with sleep-disordered breathing undergoing tonsillectomy when compared with traditional opioid-containing techniques. It is expected that this OFA regimen will have a measurable reduction on postoperative respiratory depression in children with sleep-disordered breathing.
The purpose of this study is to determine if VF001-DP improves wound healing in chronic venous leg ulcers compared to standard care only.
The purpose of the investigation is to assess iodine status of pregnant women at week 16 of gestation targeting serum thyroglobulin as a biomarker of iodine deficiency. The investigators aim to assess whether pre-gestational initiation of iodine supplementation is more advantageous in comparison to supplementation start at the time of pregnancy detection.
The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
Anticoagulant treatment reduces the incidence of death and cardioembolic events in patients with atrial fibrillation or prosthetic heart valve and the incidence of death and recurrences in patients with VTE. Warfarin and similar vitamin K antagonists (VKA) have been the standard therapy for patients with a metallic valve, or bioprosthesis with atrial fibrillation (AF). The Dabigatran versus Warfarin in Patients with Mechanical Heart Valves (RE-ALIGN) trial comparing dabigatran etexilate to warfarin was the only randomized controlled study in patient with mechanical valve prosthesis, but it was terminated prematurely because of an excess of thromboembolic and bleeding events among patients in the dabigatran group. To date, novel oral anticoagulants (NOACs) have shown to be not both safe and or effective for patients with mechanical valves.
Main objective: to observationally assess the efficacy and safety of different antimicrobials in BSI due to ESBL or carbapenemase-producing Enterobacterales in SOT. Secondary objectives: 1. To evaluate the efficacy and safety of different antibiotics used for the treatment of infections caused by ESBL- and carbapenemase-producing Enterobacterales in the SOT population. 2. To compare the efficacy of different antimicrobials between SOT and non-SOT patients (using matched controls from the "non-transplant" INCREMENT cohort). 3. To create a microbiological collection of ESBL- and carbapenemase-producing Enterobacterales isolated from the SOT population. 4. To provide data on specific MICs for each antimicrobial evaluated. 5. To provide data on the prevalence of specific mechanisms of resistance and their clinical impact in the particular setting of SOT. 6. To organise an international consortium capable of developing high quality prospective cohort studies and randomised clinical trials in the area of MDR and XDR Enterobacterales in SOT.
Pressures measured by manometric solid-state catheters may differ according to the type of the catheter and specific anatomy and physiology of anorectum. The aim of the study is to establish the difference in recordings between 2 types of anorectal catheters used in pediatric patients and to validate the most appropriate way to diagnose of functional disorders.
Today, dentists tend to use rotary systems. Despite the increasing diversity of these systems as well as a few studies on the prevalence of pain after root canal treatment by rotary systems, And in particular, comparing the amount of pain after treatment, between systems RECIPROCAL AND FULL ROTATION single-file, the aim of this study was to evaluate the effect of applying canal preparation by the system, Neolix and WaveOne, on the prevalence of pain after endodontic treatments.
Ticagrelor is a direct-acting, reversible platelet P2Y12 receptor inhibitor recommended by the recent European Society of Cardiology guidelines in patients with acute coronary syndromes (ACS) (class of recommendation I, level of evidence B). Ticagrelor inhibits platelet function stronger, faster and more consistently than clopidogrel, the former standard of antiplatelet therapy. In the landmark PLATO trial (Study of PLATelet inhibition and patient Outcomes), ticagrelor therapy as compared with clopidogrel treatment was associated with the reduced occurrence of major adverse cardiovascular events and all-cause mortality, but also resulted in a small, but statistically significant, increase in the rate of major bleeding. The optimum choice of antiplatelet treatment, aimed to provide each patient with maximum protection against ischemic events, while minimizing the risk of bleeding complications, is the challenge of contemporary ACS therapy. The tool which may help physicians and facilitate clinical decision making is platelet function testing. According to the guidance of both European and American groups of experts, there are three currently recommended platelet function tests, namely the VerifyNow device, the Multiplate analyzer and the Vasodilator Stimulated Phosphoprotein Phosphorylation (VASP) assay. It needs to be emphasized that none of these three methods is preferred over others. So far there are no studies linking pharmacokinetic analysis of ticagrelor and its active metabolite with comparative evaluation of platelet reactivity. The aim of this trial is to assess the relationship between concentrations of ticagrelor and its active metabolite (AR-C124910XX) and results of all three recommended platelet function tests in patients with myocardial infarction. Patients who receive GP IIb/IIIa receptor inhibitor will be excluded from the primary analysis. Statistical analysis: The correlation will be assessed using correlation coefficients and intraclass correlation coefficients. while the agreement between the results of the compared platelet function tests will be measured using the Kappa statistic and Bland-Altman analysis.
Patients undergoing semi-elective lower extremity major amputation from complications associated with atherosclerotic limb ischemia will received intra-muscular injections of allogeneic Mesenchymal Stromal Cells in the leg above and below the point of amputation to prevent ischemic wound complications after surgery and decrease the incidence of revision and further amputation. Cohort Groups 1-4 will serve as controls.
