Filter by:Peripheral arterial disease (PAD) can progress to critical limb ischemia (CLI) of the affected lower limb, characterized by pain at rest, ulcerations or gangrene, with a high risk of amputation. In this phase, the best treatment is arterial limb revascularization, but this is not always possible or even effective for promoting pain relief, healing of ulcers or preventing amputations, in addition to the high socioeconomic cost caused by the disease. Recent advances in cell therapy represent a promising supporting alternative for the treatment of PAD in cases where conventional alternatives have run out. Objective: To evaluate the safety and efficacy of cell therapy with expanded autologous mesenchymal stem cells in the treatment of patients with PAD with CLI and chronic arterial ulcers. Methods: An open randomized clinical study will be performed with 2 groups of 20 patients with CLI: in group 1, a fragment of abdominal fat tissue (10g) will be collected to obtain mesenchymal stem cells, which will be expanded and applied using subcutaneous perilesional injection in the affected lower limb, in addition to the application in the form of a personalized curative biological on the wounds. Group 2 will receive conventional treatment with a Hydrogel dressing with essential fatty acids. Periodic clinical evaluations, complementary exams and photographic record will be carried out. The main outcome of effectiveness will be partial or total wound healing. Safety outcomes will be monitored for infections, gangrene, amputations and deaths. Participants will be monitored for 120 days. Major amputation cases will not be included. An independent external evaluator and blind to the groups will evaluate the results. It is an innovative procedure with high impact and financial return for SUS, in view of the high prevalence of the disease and the high socioeconomic impact of the disease when it progresses to limb amputation.
A Phase 2a Multi-Center, Prospective, Randomized, Controlled Study to Evaluate the Safety and Efficacy of Topically Applied PEP-TISSEEL in Subjects with Diabetic Foot Ulcers (DFU)
Diabetic foot ulcer; It is a disease used to describe a series of lower extremity complications that may occur together with infection, ulceration or gangrene in individuals with diabetes and is coded as S91.3 and S91.8 in the International Classification of Diseases (ICD). Sharp debridement, one of the treatments for diabetic foot ulcers, is a short-term application performed with a sharp scalpel or scissors at the patient's bed or in outpatient clinic conditions. It should be performed by a skilled clinician with wound training. To our knowledge, no study has been found in the literature regarding the use of a stress ball as an intervention to prevent pain and anxiety during sharp debridement. In line with this information, this study will examine the effect of stress ball use on the pain and anxiety levels of patients with diabetic foot ulcers during wound debridement.
Foot ulcers and amputations are a common and feared complication for people with diabetes. People with a diabetic foot ulcer have a higher risk of dying within five years than people with diabetes without an ulcer. At least one in four people with a new diabetic foot ulcer will die within five years, largely due to cardiovascular causes. The reasons for this increased mortality involve decreased mobility. People with a recently healed diabetic foot ulcer are considered "in remission" as opposed to "cured" because the underlying medical problems which led to their ulcer are still present. Once in remission, the current standard of care is to slowly increase ambulation. The problem is that people rarely return to the recommended level of mobility. The ability to safely maintain mobility with aging is critical. This pilot study is a small clinical trial to test the feasibility and acceptability of a home-based exercise regimen. The investigators will also assess if this home-based exercise regimen can increase mobility and function without increasing diabetic foot ulcer recurrence by improving lower extremity strength, lower extremity tissue perfusion and glycemic control.
The goal of this observational study is to learn about the mechanism of action of ozanimod in patients with ulcerative colitis (UC). The main questions it aims to answer are: 1. Prospectively assess the effects of ozanimod on the cellular composition of intestinal lamina propria and blood by deep immunophenotyping (CyTOF) of immune cell subsets prior and after the drug's administration. 2. Determine whether changes in cell subsets observed via mass cytometry correlate with with clinical or histologic parameters of disease activity. Colonic biopsies and peripheral blood samples will be collected from patients with UC before and after the onset of ozanimod. Researchers will compare intestinal and peripheral leukocytes before and after the drug's administration.
The project aims to implement the Internet Of Thing (IoT) platform of the San Raffaele Hospital (OSR) with data from stress conditions perceived by the patient through the synergistic collaboration between patients, gastroenterologists and psychologists.
The purpose of this study is to compare how effective and how tolerable two different bowel preparation laxatives are for colonoscopy. The aim is to compare oral sulfate solution (OSS) to another laxative called 2L polyethylene glycol (PEG) solution to see which is more effective and more tolerable by individuals with IBD (Crohn's disease or Ulcerative colitis).
The objective of this clinical trial is to assess the effectiveness of acetic acid in patients suffering from chronic cutaneous ulcers with biofilm. The primary question it seeks to address is whether acetic acid (as a 2% topical solution) is superior to the current standard treatment for chronic cutaneous ulcers with biofilm at our center (Prontosan®). Participants will be randomly assigned to receive either the acetic acid solution treatment or the standard current treatment.
The purpose of this real world non-interventional study is to learn about the effects of etrasimod as treatment for patients with moderate to severe ulcerative colitis. Patients will be treated according to standard of care and will only be included in the study if etrasimod is the best treatment choice according to the treating physician. Additionally, patients have to be between 18 and 65 years of age and should not have taken etrasimod in the past. All patients will be prescribed etrasimod according to standard of care. Assessments will be conducted according to standard of care with the exception of health questionnaires which will be completed by the patients online on their own device. The study duration is 52 weeks with 28 days of safety follow-up. Patients will visit their treating physician as they would if they were not enrolled in the study. During the study duration, patients will be asked to complete health questionnaires on a regular basis either on their mobile phone, tablet or computer. The effects of etrasimod will be analyzed for each patient comparing to their disease activity prior to the start of etrasimod.
Pressure ulcers are a global issue and substantial concern for healthcare systems. A review of the literature between January 2000 and December 2012 has revealed that prevalence rate of pressure ulcers in aged care facilities were between 4.1% and 32.2%, and the incidence rates ranged from 1.9% to 59%. Similarly, a systematic review reported that the prevalence of pressure ulcer varied between 0.3% and 46%, and the incidence of pressure ulcer ranged from 0.8% to 34%. Most epidemiological data were obtained from hospitals (38.7%) and institutional long-term care facilities (29.7%). The costs associated with pressure ulcers are considerable. According to the Agency for Healthcare Research & Quality (2011), the US healthcare system has allocated approximately $ 9.1 - $ 11.6 billion annually for the health care cost of pressure ulcer. In addition to direct treatment-related costs, the development of pressure ulcer also results in litigation and government penalties, and affects hospital performance metrics. A systematic review has reported that the cost for treatment of pressure ulcer was higher than its prevention. That is, the cost per patient per day ranged from € 1.71 to € 470.49 (for treatment) and from € 2.65 to € 87.57 (for prevention) across all settings. This randomized controlled trial will be performed in a general hospital in a random sample of 308 patients (nursing wards geriatric n=3 and orthopedic (n=3)) who are at high risk of developing pressure ulcers. Patients will be included in the study for a period > 2 hospitalisation days. Skin assessment and risk factor registration will be done on a daily base by the ward nurses. Reliability checks and time measurements will be completed by the researcher.
