Filter by:The investigators hypothesize that the combined use of CADe system (ENDOAID) and mucosal exposure device (Endocuff Vision®) would improve the adenoma detection rate when compared to CADe system alone.
The investigators aim to evaluate and compare the diagnostic accuracy of FIT and the novel panel of bacterial gene markers (Fn, m3, Ch and Bc) collectively named as M3, in detecting colorectal advanced neoplasia.
The SPARC-C study is a prospective, single-centre observational study of patients referred for the management of large (≥ 20mm) non-pedunculated colorectal polyps (LNPCPs). Patients are managed consistent with current standards of care. Prospectively collected data includes: patient clinicodemographic details, lesion details, procedural details, and clinical outcomes.
The overall goal of this study is to develop a platform for both large-scale chemoprevention trials and real-world chemoprevention studies for colorectal cancer (CRC) prevention. The specific objectives of this proof of concept study are to: 1. Evaluate the feasibility of a real-world chemoprevention agent (CPA) intervention (3-months of daily low-dose acetylsalicylic (ASA)) in participants at increased risk for CRC (one or more high-risk adenomas removed during colonoscopy) based on participant uptake, adherence (days taking CPA), and adverse events; 2. Evaluate factors related to uptake and adherence of ASA using validated surveys and interviews.
The purpose of this study is to compare the effectiveness of three standard of care outreach approaches (i.e., mailed letter, secure message, and telephone call) on patient adoption of the new 10-year colonoscopy surveillance interval recommendation for a random sample of health plan members who have a now-outdated 5-year surveillance interval due to a finding of 1-2 small adenomas at their prior colonoscopy. The primary study endpoint is the proportion of patients in each outreach arm who adopt the new 10-year colonoscopy surveillance interval.
Over the last 5 years, prostate embolization has developed as a treatment for symptomatic prostate adenoma. This long, complex procedure is effective in 80% of cases. Currently there are no means of better selecting patients to avoid this long procedure in non-responders. The hypothesis is that prostate perfusion parameters are correlated with the efficacy of embolization. Studying these prostate perfusion parameters in perfusion CT and evaluating prostate Iodine load in dual energy computed tomography will make it easier to select those patients who are most likely to respond.
The investigators hypothesize that gut microbiome composition and the four bacterial gene markers (M3) show dynamic changes after endoscopic resection of advanced neoplasia, some key bacteria are associated with restoration of gut microbiome after endoscopic resection.
In this study, the investigators will perform endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) treatment of left-sided adrenal tumours in patients with primary aldosteronism (PA) and in patients with mild autonomous cortisol secretion (MACS). Four different study groups will all receive EUS-RFA of left-sided adrenal tumours. Clinical and biochemical outcome as well as procedural safety will be evaluated. In study patients with verified lateralised aldosterone or cortisol overproduction to the left adrenal, outcome will be compared with control groups performing conventional unilateral adrenalectomy. Study group 1: PA patients with AVS-verified left sided lateralisation and a EUS-detectable tumour in the left adrenal for EUS-RFA treatment. Study group 2: PA patient with suspected left-sided overweight of aldosterone production and a EUS-detectable tumour but without strict lateralisation of their aldosterone overproduction, for EUS-RFA treatment as an aldosterone "debulking" procedure. Study group 3: patients with MACS with AVS-verified lateralisation of cortisol overproduction to the left adrenal and EUS-detectable tumour for EUS-RFA treatment Study group 4: patients with MACS with bilateral adrenal tumours and verified bilateral overproduction of cortisol for EUS-RFA treatment as a cortisol "debulking" procedure.
This multi-center study will compare multi-target DNA and quantitative FIT stool-based testing to colonoscopy in individuals with Cystic Fibrosis (CF) undergoing colon cancer screening with colonoscopy. The primary endpoint is detection of any adenomas, including advanced adenomas and colorectal cancer (CRC).
Purpose of this clinical phase 1 trial was to determine if para-chloro-2-[18F]fluoroethyletomidate positron emission computed tomography ([18F]CETO-positron emission computed tomography(PET)/computed tomography(CT)) can be used in diagnostics of adrenal tumors and if the biochemical/pharmacological states conditions in humans with various illnesses, compared to healthy humans, such as the radio tracer is suitable?
