Filter by:The primary aim of this study is to demonstrate the impact of the Orpyx® SI Sensory Insoles (Orpyx Medical Technologies Inc., Calgary AB, Canada) ("Orpyx" or "the Company") as an adjunct to the standard of care (SOC), as compared to SOC alone, on reducing plantar ulceration incidence in individuals who are at risk for developing diabetic foot complications. The secondary aims of this study are to evaluate participant quality of life, participant engagement, and economic impact, including cost-effectiveness and cost-utility. The study will also use the unique data set collected (plantar pressure, temperature, step count, movement and adherence feedback) to identify foot-loading histories that either lead to or prevent the development of ulceration in the diabetic foot.
Various treatment options have been proposed in managing NK such as preservative-free lubrication (PF-L), withdrawal of epitheliotoxic medication, prophylactic antibiotics, applying of bandage contact lenses, using hemoderivatives 8, topical insulin, recombinant nerve growth factor (rNGF) or epidermal growth factor (rEGF).11,12, amniotic membrane transplant (AMT), or corneal neurotization.2,4,9,10 Topical insulin has been reported to effectively promote the healing of persistent corneal epithelial defects. In our retrospective study, we explored the safety and efficacy of topical insulin, as a first-line treatment, in treatment-naïve acute NK after diabetic vitrectomy.
Ulcerative Colitis (UC) is a chronic Inflammatory Bowel Disease (IBD) characterized by a multifactorial etiology, a variable involvement of large bowel, and a relapsing-remitting course. In order to keep the disease in a "quiescent" status and to prevent relapses, a significative percentage of UC patients will remain on long-term drug therapy. However, long-term immunosuppressant therapy is not free of risks and complications: in fact, these therapies have an impact on both healthcare system resources and patients' quality of life; more, there are even concerns regarding the side effects of long-term immunosuppressant therapy. Over the past 20 years, a considerable amount of evidence was produced to support the immunomodulatory role of the appendix in the development and course of UC: there is a strong inverse relationship between previous appendectomy and development of the UC. One of the proposed theories to justify this link is that the appendix could act as a reservoir for commensal bacteria that can be secreted into the colon, affecting its microbiome and immunological response; another theory describes the appendix as the "priming site" for the cytokine production and the immunological cascade that may trigger inflammation in colon and rectum. The idea of this study moves from these assumptions: the investigators aim to evaluate the impact of appendectomy in patients with UC who are candidates to the treatment with biologics (Anti TNF-a), because of conventional therapies failure. To further reduce any ethical problems and significantly lower any surgical morbidity, investigators will restrict the study population to only patients with active left-sided colitis, so that the surgery for appendectomy will take place on a non-inflamed cecum. By undertaking this study, the investigators hope to a) learn more about the role of appendix and the impact of appendectomy in the clinical history of Ulcerative Colitis; b) demonstrate that laparoscopic appendectomy, a relatively simple surgical procedure that can also be performed in day-surgery with a very low expected complication rate, is a treatment that is superior to biological therapy, avoiding patients starting a chronic, long-lasting therapy, with the consequent risk of immunosuppression, and with possible higher costs for the health system in the long term.
Patients with chronic ulcer needing tertiary care referred to the Wound Center of Tampere University Hospital are invited to this study. Patients are treated according to standard treatment practices. The temperature of the lower limbs and ulcer area is measured during visits using the Thermidas Remote thermal imaging system, a CE-marked medical device for measuring and monitoring changes in skin surface temperature non-invasively. The measured temperatures and differences are compared in different ulcer aetiology groups and analyzed whether thermal imaging can be used to distinguish atypical ulcers from vascular ulcers. Thermal imaging measurements and clinical examinations are repeated to the patients with atypical ulcers during follow-up visits. Monitoring of ulcers will continue until the ulcer has epithelized completely or for up to a year.
This Phase 3 study is a randomized, double-blind, vehicle-controlled, multiple-center, parallel study to evaluate efficacy and safety of ENERGI-F703 GEL compared with vehicle control in subjects with Wagner Grade 1 to Grade 2 diabetic foot ulcers. Baseline target ulcer size (<16 cm2 vs ≥16 cm2 ) will be included as a stratification factor. Subjects will be randomized 1:1 to receive ENERGI-F703 GEL or vehicle control using an interactive web response system for randomization to automatically assign a unique subject randomization number. Total duration of the study will be up to 31 weeks including Screening visit (approximately 2 to 3 weeks), double-blind dosing/observation phase (16 weeks), and a safety follow-up of 12 weeks after the last administration of study treatment.
The opioid growth factor-receptor antagonist-naltrexone hydrochloride (NTX)- has gained much reach interest for applications in ophthalmology, because of its novel mechanism of action for speeding up corneal wound healing in both diabetics and non-diabetics, effective both locally and systemically and its availability as a low molecular weight synthetic drug.
The goal of this clinical trial is to evaluate the use of Omeza combination therapy with Standard of Care. The main question it aims to answer is: - Can Omeza combination therapy with Standard of Care enable chronic wounds to begin a healing trajectory in a 4-week period? Patients will be treated with: - OCM™ Wound Matrix - Omeza combination therapy - Standard of Care
A prospective randomised controlled experimental study was planned to compare the effects of pressure sore dressing using topical haemoglobin and traditional gauze dressing using saline on the healing process and cost of pressure sores in patients with pressure sores.
Ulcerative colitis (UC) is a chronic persistent inflammatory disease. The lesions are mainly confined to the large intestine and continuously affect the rectum and part or all of the colon. Its histological characteristics are diffuse neutrophil infiltration in the lamina propria of the colon mucosa, mucosal erosion, ulcer, cryptitis, and crypt abscess. The most common clinical manifestations are abdominal pain, diarrhea, and bloody mucopurulent stool, accompanied by extraintestinal manifestations such as mouth, skin, joints, and eyes. Severe lesions can be complicated by toxic megacolon, intestinal perforation, lower gastrointestinal hemorrhage, intraepithelial neoplasia, and cancer, so surgical treatment is necessary. Studies have reported that UC patients have a 10-year cumulative recurrence risk of 70%-80%, nearly 50% of patients require UC-related hospitalization, and the 5-year risk of re-hospitalization is ~ 50%. The 5-year and 10-year cumulative risk of patients undergoing colectomy is 10%-15%, which dramatically endangers the health of patients and reduces the quality of life of patients. Currently, the commonly used medical treatment drugs for UC patients include 5-aminosalicylic acid, topical and systemic glucocorticoids, immunomodulators, anti-tumor necrosis factor drugs, and other biological agents. The most commonly used optimization methods are drug escalation therapy and combining drugs with different mechanisms. The real-world data results of an initial population-based cohort study from six Asian countries showed that the endoscopic mucosal healing rate of patients with ulcerative colitis in the first year of diagnosis was 38.2%, and the histological mucosal healing rate was 23.1%. It can be expected that the mucosal healing rate of patients with moderate to severe UC may be lower. Long-term chronic recurrent diseases may lead to poorer quality of life, extended hospital stays, heavier financial burdens, and more physical and mental pain. Therefore, optimizing the treatment plan for patients with moderate to severe UC needs more exploration and research. Autologous Platelet-rich plasma (A-PRP) is A platelet-rich concentrate obtained by centrifugation of whole blood. As a concentrated source of autologous platelets, they contain a large number of Growth factors (GF) and cytokines, such as platelet-derived Growth factor (PDGF), transforming growth factor β(TGF-β), vascular endothelial growth factor (VEGF) and epithelial growth factor (EGF), which regulate cell function. Such as attachment, macrophage migration, proliferation, and differentiation, promote extracellular matrix accumulation and ultimately improve tissue healing and regeneration. At the same time, A-PRP has A lower risk of adverse reactions such as immune rejection and allergy due to its isolation from autologous blood. After PRP is induced by activators such as calcium and thrombin, activated platelets degranulate immediately and secrete multiple high concentrations of growth factors. 70% of the growth factors can be released within 10 minutes of activation, and more than 95% can be released within the first hour. Platelet-rich Gel (PG), which can embed growth factors to improve clinical efficacy, keeps platelets and their release products in the target wound area and promotes healing. Although the safety and efficacy of PRP still need to be fully confirmed by large-scale clinical trials, its sound effect has been verified in many clinical practices and basic scientific research in cell culture and animal models. At present, it mainly includes the treatment of oral and maxillofacial external, musculoskeletal system, plastic skin, and chronic wounds (such as pressure ulcers, venous leg ulcers, diabetic foot ulcers, etc.). They can be mixed into bone grafts, sprayed on soft tissue surfaces as a biofilm, or made into eye drops. The use of PRP in intestinal mucosal ulcers has rarely been reported. There are no prospective randomized studies of its clinical use in patients with ulcerative colitis. Therefore, we planned to conduct a prospective, randomized, double-blind, controlled clinical trial to investigate the efficacy and safety of repeated treatment with autologous platelet-rich plasma gel on an intestinal mucosal ulcer in patients with moderate to severe UC involving the rectum in Xijing Hospital, China IBD Regional Center. To provide a new option for remission induction therapy in patients with moderate to severe ulcerative colitis.
