The purpose of this research study is to determine if treatment with Elagolix will improve body weight, waist circumference, muscle strength, cortisol secretion, blood glucose, cholesterol, and bone quality as well as mood and quality of life in a female patient with mild hypercortisolism from adrenal overproduction of cortisol. Many people with adrenal nodules, or non-cancerous growths in the adrenal glands, have mildly elevated cortisol levels. Cortisol is a hormone normally made by the adrenal glands. It is increasingly being recognized that even mild elevations in cortisol levels can negatively impact blood glucose levels, serum cholesterol levels, weight and other metabolic parameters. This can lead to an increase in risk for cardiovascular disease. The study team is trying to determine if the medication Elagolix might be an effective treatment for post-menopausal females with mild hypercortisolism. Elagolix is a medication used to treat a medical condition called endometriosis by decreasing the body's production of sex hormones. Growth of adrenal adenomas is thought to be driven by such sex hormones. Therefore, by decreasing production of these hormones, the study team hopes to treat hypercortisolism caused by adrenal adenomas.
Endoscopic papillectomy is the preferred approach for management of ampullary adenomas. Endobiliary radiofrequency ablation (RFA) is an ablative therapy that has been used to treat malignant biliary strictures. The aim of this study was to evaluate the safety and efficacy of endoscopic papillectomy combined with endobiliary RFA for ampullary neoplasms with intraductal biliary extension.
This study will see if the use of near infrared autofluorescence (NIRAF) detection with an FDA-cleared device 'Parathyroid Eye (PTeye)' for identifying parathyroid glands (PGs) during parathyroidectomy (PTx) procedures is better than a surgeon's detection alone. It compares risk-benefits and outcomes in PTx patients where NIRAF detection with PTeye for parathyroid identification is either used or not used.
The investigators' null hypothesis is that a withdrawal time of 9 to 10 minutes is non-inferior to a withdrawal time of 12 minutes or greater. Thus, the goal of this tandem design trial is to compare the additional diagnostic yield (# of missed lesions) for withdrawal times exceeding 10 minutes for screening/surveillance colonoscopies. Although withdrawal times longer than the standard 6-minute recommendation have been shown to be beneficial, there is limited prospective evidence investigating the benefit or lack thereof for withdrawal times greater than 9-10 minutes.
In multiple previous studies that have explored the use of dexmedetomidine in transsphenoidal tumor resection surgery, dexmedetomidine showed many beneficial effects like reducing the requirement of analgesics and anesthetics, improving hemodynamic stability and decreasing the emergence time, extubation time and visual analog scale at emergence. Therefore, the investigators hypothesized that dexmedetomidine would decrease neuroendocrine stress response and improve the quality of postoperative recovery.
The CELTiC panel is a potential blood-based test for detecting colorectal cancer (CRC) and precursors of CRC. This can be useful for CRC screening, since this requires tests that detect cancer in an early stage to maximize the chances of successful treatment. CELTiC combines four markers that can be detected in blood. These markers are composed of so-called messenger RNA (mRNA) and can be viewed as the instructions of our genes to the cell to make certain proteins. Cancer is the result of mutation in these genes. Thus, the mRNA in cancer patients is, depending on the type of mRNA, often abnormal. In earlier studies, the developers of CELTiC found four mRNA's that are different in patients with CRC compared to healthy individuals. However, CELTiC has not yet been extensively studied in individuals for whom the test is intended: a population undergoing CRC screening. The current study aims to fill this gap. We will assess the ability of CELTiC to detect CRC and precursors of CRC in a population of individuals between 50 and 75 years old in the Netherlands and Italy. This population has already been preselected by having a positive fecal immunochemical test (FIT), a test that is frequently used in CRC screening. This population will undergo a colonoscopy, a procedure where a doctor enters the large bowel through the anus using a flexible camara to assess whether the patient has cancer. Prior to this colonoscopy, we will collect blood samples from the individuals to assess their CELTiC score. After the colonoscopy and the blood analysis, we can assess whether the test adequately detects CRC and precursors of CRC in this population.
This study is intended to demonstrate the superiority of colorectal polyp detection using computer-assisted colonoscopy compared to conventional colonoscopy.
Colorectal cancer (CRC) screening programs have been implemented to reduce the burden of the disease. When an advanced colonic lesions is detected, it is recommended to perform endoscopic surveillance with different intervals between explorations. Although the reduction in CRC incidence, endoscopic surveillance is producing a considerable increase in the number of colonoscopies. However, participation in CRC screening programs based on the fecal immunochemical test (FIT) could be a non inferior alternative to endoscopic surveillance. Based on this hypothesis, the research group have designed a randomized clinical trial within the population CRC screening programs to compare FIT surveillance to endoscopic surveillance in patients with advanced lesions resected.
To evaluate the impact of second forward view examination of the proximal colon on adenoma detection rate Inclusion criteria：Patients ≥18 years of age undergoing screening, follow-up monitoring, and diagnostic colonoscopy Exclusion criteria：①Cecal intubation failed. ②Have a history of colorectal surgery. ③Insufficient bowel preparation, inadequate bowel preparation quality (Boston Bowel Preparation Scale (BBPS)scores < 2 in any segment of the colon). ④Inflammatory bowel disease or intestinal tuberculosis. ⑤Familial polyp syndrome. ⑥polyp retrieval failure. ⑦Patients with coagulation dysfunction. Patients ≥ 18 years of age who came to our hospital's Digestive Endoscopy Center for screening, follow-up monitoring and diagnosis of colonoscopy. After successfully insert the cecum, colonoscope withdrawal to the splenic flexure, all polyps found during the withdrawal process were resection,then they were randomized to standard withdrawal colonoscopy or second forward view according to the random number table (1:1) to perform.
