Active clinical trials for "Ulcer"

This is an observational, longitudinal real world registry of diabetic foot ulcers created from electronic health record data obtained in the course of clinical care. Data from certified electronic health records transmit data as part of the requirement to share data with a specialty registry under Objective 10 of Meaningful Use of an EHR.

The worse prognosis observed in patients with Diabetic Foot Ulcer (DFU) has not been fully understood. Poor prognosis may be related to other conditions (inflammation, infectious disease, cancers) further to cardiovascular disease. The aim of the study is to conduct the first prospective, observational and multi-centre cohort of patients with DFU in France, in order to evaluate the 5-years mortality rate, its causes and relevant prognostic determinants.

People with neuromotor disability (i.e. following an inborn or acquired spinal cord, cerebral or peripheral neurological lesion) are at high risk of osteomyelitis-associated pressure ulcers. The management of osteomyelitis-associated pressure ulcers is controversial. In our center, patients benefit from a one stage surgical management with bone shaving and flap covering osteitis of pressure ulcer to perform wound closing. Surgery is followed by an antibiotic treatment, secondarily adapted to intraoperative samples. The aim of this study is to describe the cohort and to identify factors associated with failure (or success) in this frail population.

More than 100 hospital based outpatient wound centers in the USA and Puerto Rico agree to transmit structured data on all patients followed with chronic wounds and ulcers (e.g. diabetic foot ulcers, venous ulcers, pressure ulcers, arterial ulcers, surgical wounds, and traumatic wounds). Data are collected at point of care including adherence to wound care quality measures developed by the USWR as a Qualified Clinical Data Registry (QCDR).

The investigators hope that the present study will highlight new transcriptomic prognostic markers of response to Ustekinumab with the ultimate goal of individualizing treatment and making a more targeted selection of UC patients who will benefit from this biological agent.

This prospective observational study is going to develop and validate a prediction model of response to biologic agents and small molecular agents for Korean patients with ulcerative colitis.

Chronic Venous Disease (CVD) is a widespread clinical condition widely spread in the western countries that may negatively impact the quality of life (QoL) of affected patients. Chronic venous leg ulcers (CVLUs) are the most severe form of CVD, and several genetic and molecular alterations have been studied in order to understand the progression of CVD towards CLVUs. Chronic inflammation is a key element in CVLUs onset, and recently T helper 17 (Th-17) cells, a subtype of pro-inflammatory T helper (CD4+) cells defined by the production of a cytokine signature of which IL-17 represents the progenitor, seem to be related to several chronic disease. The aim of this study is to evaluate Th17- Gene Expression profile in patients with CVD and CVLUs.

The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).

Patients presenting with severe symptoms of ulcerative colitis (UC) require hospital admission for urgent assessment and therapy. Endoscopic examination of the rectum and/or distal colon is often performed to assess severity and obtain tissue for histopathologic evaluation, but this is often extended to full colonoscopy to assess the extent of bowel involvement. Full colonoscopy is hazardous in this setting

Up to one third of patients with Ulcerative Colitis (UC) will require hospitalisation for severe disease (ASUC - Acute Severe Ulcerative Colitis), often within the first 12 months of diagnosis. 30-40% of people admitted to hospital with ASUC will require colectomy during the emergency admission. Investigators will develop a multi-centre prospective inception cohort of patients with ASUC with homogeneously collected detailed longitudinal clinical, endoscopic and laboratory data.
