Active clinical trials for "Necrosis"

This is a retrospective chart review study examining 1) demographic data such as age, sex, etiology of pancreatitis 2) clinical data including radiological characteristics of walled off pancreatic necrosis, walled off necrosis related admissions and readmission following endoscopic drainage, surgical or percutaneous procedures performed for the management of walled off pancreatic necrosis, and clinical outcomes following treatment of WON (including hospital readmissions, WON resolution, procedure complications, WON related death) 3) endoscopy data including indication for initial endoscopic drainage and subsequent endoscopic procedures performed for management of walled off necrosis (including additional EGD's, endoscopic drainage procedures, and/or necrosectomy)

An observational study assessing the impact of anti-citrullinated antibody (ACPA) in rheumatoid arthritis (RA) participants who have received abatacept or tumour necrosis factor inhibitors (TNFi) from the Optimising Patient outcome in Australian rheumatoLogy (OPAL) registry

Introduction: osteonecrosis of the femoral head is a potentially crippling disorder, which mainly affects the young adults. Core decompression has been used for the treatment of the osteonecrosis of the femur head since was published by Ficat and albert, and by HUNGERFORD and Lennox. hyperbaric oxygen therapy is a suggestive joint preserving treatment for symptomatic prolapse stage of osteonecrosis of the femur head. Aims and objectives: to compare the clinical (functional) outcome of core decompression versus hyperbaric oxygen therapy in pre collapse stages of idiopathic avascular necrosis of the femur head. Material and methods: Mixed Retrospective and prospective study for all case of pre collapse of avascular necrosis of femoral head(AVNHF) underwent either hyperbaric oxygen therapy or Core decompression augmented with bone substitute in HAMAD General Hospital Anticipated outcome: Hyperbaric oxygen treatment associated with better outcomes at preserving the joint and associated with less complications than surgery

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.

The study will evaluate the radiographs (x-rays) of 100 patients with a TriFIT total hip at 2 weeks, 3 months, 6 months, 12 months, and yearly following surgery to see if there has been any movement or wear in the hip stem over the course of the study. The study will also record clinical data on each patient using various functional tests and questionnaires at the same intervals.

This protocol is for a clinical trial to evaluate the reliability of the bite fork as a diagnostic instrument in subjects with pulpal necrosis and apical periodontitis.

This study will evaluate the performance of biologically assisted core decompression with the PerFuse instrument and BioCUE in patients with bone lesions in the femoral head. The study will explore the potential impact of patient demographics and baseline characteristics on post-operative outcomes.

The purpose of the Hyperbaric Oxygen Therapy Registry (HBOTR) is to provide real world patient outcome and side effect information from electronic health records submitted to a specialty specific hyperbaric registry as part of "Stage 2 of Meaningful Use," including data provided to meet PQRS requirements via the registry's QCDR mission. Goals include understanding the value of HBOT among patients treated for a variety of conditions in relation to the frequency and severity of HBOT side effects. While randomized, controlled trials can establish the efficacy of treatments like HBOT, because they routinely exclude patients with co-morbid conditions common to those patients seen in usual clinical practice, the results of RCTs are usually non-generalizable. Real world data can be used to better understand the effectiveness of HBOT among typical patients, as well as the risks associated with treatment.

Multiple predictors have been used for early pancreatic necrosis, prediction, detection, and monitoring. These include clinical score systems and circulating biomarkers. Ranson and APACHE II score systems are widely used albeit complex and time-consuming. Recently, the role of circulating biomarkers . Of these novel biomarkers, only CRP has been used routinely in cases of pancreatic necrosis prediction. Mitochondrial DNA (mtDNA) is an extra chromosomal genome occurring in the mitochondria of eukaryotic cells. High levels of mtDNA suggest the presence of pancreatic necrosis and close observation should be given to avoid the development of SAP and pancreatitis infection.

The aim of this study is to prospectively evaluate the effect of intra-operative Indocyanine green angiography (IGA) on both flap design and rate of post-operative fat necrosis in patients undergoing autologous breast reconstruction utilizing the Deep Inferior Epigastric Artery Perforator (DIEP) flap.
