Active clinical trials for "Ulcer"

The aim of this study is to compare quality of life of diabetics with and without foot ulcer. Investigators will compare their quality of life based on the mental health impact of foot ulcer.

The risk of colorectal cancer (CRC) is increased in patients having ulcerative colitis (UC). Patients with long-standing extensive colitis, concomitant primary sclerosing cholangitis, or previous history of dysplasia carry an exceptionally high risk of CRC and require regular and short-interval surveillance colonoscopy. Recent guidelines recommend surveillance colonoscopy based on target biopsy rather than random biopsy applying chromoendoscopy (CE) or narrow band image (NBI) technique in UC at risk for CRC. However, the diagnostic yield of NBI-based surveillance and CE-based surveillance is not extensively investigated in the high-risk UC population. The investigators aimed to compare the dysplasia detection rate of NBI with that of CE in UC patients with a high risk of CRC by performing a multicenter, randomized controlled trial.

A large number of studies are devoted to studying the effect of patient nutrition on the occurrence and treatment of pressure ulcers. Several studies, including the US National Long-term Treatment of Pressure Ulcers Study, have shown that weight loss and malnutrition were associated with a higher risk of pressure ulcers. One of the successful products specially created for the treatment of pressure ulcers and taking into account the results of research is the high-protein, energy-rich, ready-to-use enteral tube feeding food product Nutrison Advanced Cubison. It is a complete enteral nutritional supplement with an innovative nutrient composition for patients with chronic wounds, including pressure ulcers, or at increased risk of developing them. Taking into account the available data, it seems expedient to continue studying the unique combination of nutrients that make up the study food product Nutrison Advanced Cubison in order to develop the most effective nutritional protocols for patients at risk for the treatment and prevention of pressure ulcers.

The purpose of this non-interventional study (NIS) study is to assess further knowledge on the routine use of Entyvio in inflammatory bowel disease therapy, particularly the use in participants with CD and UC naive to biologics.

This study aims to characterize the changes on intestinal microbiota pattern associated with the use of golimumab in order to determine if intestinal microbiota markers may correlate with golimumab therapeutic effect in patients naïve & non-naïve to anti-TNF treatment

This is a multi-site, longitudinal study to evaluate the use of the SEM Scanner as an adjunct to clinical judgment for detection of early pressure ulcers in patients before clinical judgment using signs of pressure ulcers from skin assessments. longitudinal study to evaluate the use of the SEM Scanner as an adjunct to clinical judgment for detection of early pressure ulcers in patients before skin assessments.

The purpose of this study of this study is to assess the responsiveness and validity of CIMS (Central Image Management System)-based endoscopic evaluation of UC (Ulcerative Colitis) clinical disease activity by measuring: The responsiveness central reader endoscopic EIs [(Endoscopic Indices) (MMCS (Modified Mayo Clinic endoscopy Subscore), UCEIS (Ulcerative Colitis Endoscopic Index of Severity) MBS (Modified Baron Score)] to clinical change from baseline to week 6 in a prospective trial of a treatment of known efficacy in UC.

This study is conducted in a cohort of low dose aspirin (ASA) users previously ascertained. The aims of the post hoc analyses are: To estimate the incidence of uncomplicated peptic ulcer (UPU) in a cohort of low-dose ASA for secondary prevention of vascular disease and the relative risk of UPU associated with use and discontinuation of use of low dose ASA. To estimate the effect of proton pump inhibitors (PPI) on the occurrence of UPU among users of low-dose ASA for secondary prevention of vascular disease To evaluate the effect of other risk factors on the occurrence of UPU among users of low-dose ASA for secondary prevention of vascular disease.

This study was undertaken to identify prospectively which clinical venous leg ulcer (VLU) characteristics known as possible prognostic markers, and which sociodemographic and psychologic factors associated with VLU are associated with complete healing at 24 weeks.

The risk for colon cancer in patients with longstanding ulcerative colitis exceeding the rectum is increased and therefore patients should be enrolled in a surveillance program eight years after the diagnosis. Until today, official international guidelines for endoscopic screening in patients with ulcerative colitis advise to take 4 biopsies every 10 centimeters (with a minimum of 32) and of each suspected visible lesion. These guidelines are merely based on consensus during expert opinion meetings rather than evidence based. Recent studies have shown that chromo-endoscopy guided biopsies significantly reduced the number of biopsies for each procedure and detected more neoplastic lesions. Chromo-endoscopy is therefore considered the gold standard in this study in which we want to compare it to the performance and efficiency of new endoscopic imaging techniques. Narrow-Band Imaging (NBI) selectively uses certain wavelengths of the visible light leading to a shift in the excitation spectrum towards blue light. The first studies with NBI showed that the additional value of NBI in the detection of neoplastic lesions is comparable to chromo-endoscopy, but time saving and easier to perform. The Fujinon Intelligent Chromo-Endoscopy (FICE) system uses a similar theoretical principal as NBI but this is achieved via the use of post hoc computer algorithms, applying different filters to the stored endoscopic images and enabling a theoretically endless number of combinations of filters that can be used. The Pentax I-scan system also allows post hoc modification of the images. On the one hand, surface enhancement enables to better highlight mucosal changes. Spectral modification allows to apply different modes in analogy with to FICE system. These new imaging techniques have a theoretical advantage which is extendedly used for sales purposes but has however so far not been proven in ulcerative colitis patients. We want to test their clinical use in the screening for neoplastic lesions in patients with long standing ulcerative colitis.
