Active clinical trials for "Ulcer"

The purpose of this study is to determine whether moxibustion is effective to mild and moderate ulcerative colitis and the effect of moxibustion on metabolism.

The purpose of this study is to evaluate the effectiveness of 'enhanced' multi-disciplinary wound care teams (MDTs) vs. 'usual' care teams in Long Term Care (LTC) facilities in Ontario for the treatment of pressure ulcers. LTC facilities with more than 100 beds that are within a 100 km distance from St. Mikes and have a problem with pressure ulcers will be asked to participate. A total of 10 LTC facilities will be randomly selected (i.e. selected by chance) from those that agree to participate. The 'enhanced' MDT will be an Advance Practice Nurse(APN) with expertise in wound care who has direct access to the wound care team at St. Mikes. This APN will develop treatment plans in consultation with facility staff, providing targeted pressure ulcer treatment education on an ongoing, case by case basis. Care is supported by telemedicine with the use of digital photography and online communication between members of the care team. This study is a stepped wedge randomized trial, meaning LTC facilities are assigned to a start date for this study totally by chance. Changes in healing rates, wound related pain, cost, number of new pressure ulcers, and number of wounds healed will be measured before, and after the APN is introduced to facilities. In order to gain more insight into how people felt about this model of care, interviews will be held with individuals and groups of staff at 5 randomly selected facilities before, during, and after the study has been completed.

This is a double-blind, randomized, placebo controlled study to assess the beneficial effects of food supplementation with VSL#3 as a support to standard pharmaceutical therapy in patients affected by mild to moderate active ulcerative colitis.

This exploratory, open-label clinical study aims to explore the effects of KB295, a novel glycan, on adult patients with ulcerative colitis (UC) presenting with mild-to-moderate UC symptoms

Sickle Cell Disease is the most frequent genetic disease in the world (representing one birth over 1900, in France). The polymerization of the abnormal hemoglobin (i.e., HbS) when deoxygenated is at the origin of a mechanical distortion of red blood cells (RBC) into a crescent-like shape. Sickled RBCs are very fragile and rigid, which lead patients to have severe anemia and to develop frequent and repeated painful vaso-occlusive crises. Furthermore, the repetition of sickling-unsickling cycles causes irreversible damages to the RBCs, which shorten their half-life. Accumulation of free hemoglobin and heme in the plasma is involved in blood vessels lesions in both the macro- and micro- circulation. The resulting vascular dysfunction could explain why limb ulcers are 10 fold more frequent in patients with sickle cell disease compared to the general population and may happen at a younger age. Limb ulcers induce significant morbidity (delay of healing between 9 and 26 weeks in the french cohort), and are associated to significant pain (needing opioid pain-killer) and increase the risk of infection. Cost of care is also increased. Moreover, ulcers induce missed school and work days. Data on cutaneous microcirculation and ulcers physiopathology in patients with sickle cell disease are scarce. We want to realise a microcirculatory and neurological functional study of patients with with and without ulcers and a characterization of biomarkers present in the blood or in the wound fluid which can participate to ulcers physiopathology. To ensure healing, adapted therapeutics are essential. Several strategies are proposed such as: lifestyle measures (venous compression, lower limb elevation, rest), dressings, hyperbaric oxygenotherapy (also used in diabetic ulcers). The project is devoted to study the mechanisms involved in leg ulcers and the effects of therapeutical/behavioral strategies.

The purpose of this study is to determine whether repositioning frequency can be extended for nursing home (NH) residents who are low, moderate, and high risk for pressure ulcer (PrU) development. The investigators will also determine how changes in medical severity interact with changes in risk level and repositioning schedule to predict PrU development. This study will advance knowledge about repositioning frequency and clinically assessed PrU risk-level in relation to medical severity. Outcomes of this research will contribute to future guidelines for more precise preventive nursing practices and refinement of PrU prevention guidelines.

The investigators want to evaluate the short duration HBOT can improve glycohemoglobin (HbA1c) levels, leukocyte count, and serum creatinine levels in patients with DFU (diabetic foot ulcer) Wagner 3-4.

This is a single centre open label study measuring lower limb physiology in patients with venous leg ulcers at the University Hospital of South Manchester. Ambulatory venous pressure, venous transit times, wound bed tissue oxygenation and changes in microcirculation will be measured at baseline after the gekoTM device is activated. Ambulatory venous pressure and venous transit times will be performed whilst the participant is standing, sitting and supine

Pragmatic clinical trial, randomized, controlled parallel, 3 group (group technology platform, call group and control group), developed in the monograph Reference Unit of Inflammatory Bowel Disease Valencia (single-center).

The aim of this clinical investigation is to collect skin lesion area data for the comparison of the agreement among the results obtained between the following three wound area measurement methods: Ruler using the Kundin method, Investigational software Clinicgram Euclides Digital planimetry with Adobe Photoshop The clinical data retrieved in this study will allow the clinical validation of the safety and safety of the investigation software Clinicgram Euclides.
