NCT ID: NCT05640401 Recruiting - Clinical trials for Gastrointestinal Diseases

Holographic Screens as a Replacement of Monitors During GI Endoscopies

Start date: November 21, 2022
Phase: N/A
Study type: Interventional

Nowadays, the application and development of spatial technologies have shown an increased interest in different fields of medicine, especially in procedural specialties. Many studies have shown the utility of augmented and virtual reality; however, studies evaluating mixed reality are scarce. In gastroenterology, some proposed advantages of MR are the 3D space guidance, its increased situational awareness, remote assistance, and the reduction of surgical monitors in the units. Based on this, the researchers proposed a multicenter trial to assess the added value of MR through a holographic device during gastroenterology endoscopic procedures.

NCT ID: NCT05561179 Recruiting - Clinical trials for Gastroesophageal Reflux

Hyaluronic Acid in Patients With Gastroesophageal Reflux Disease

Start date: September 30, 2022
Phase: N/A
Study type: Interventional

Gastroesophageal reflux disease (GERD) remains one of the most common pathologies seen among gastroenterologists, surgeons, and primary care physicians. The high prevalence of this condition lead to further investigations in its prevention, diagnosis, and management. For the treatment of this chronic condition, improvement in quality of life and long-term durability should be considered. Nowadays, proton pump inhibitors (PPIs) are considered the mainstay in the treatment of the patients with GERD; however, due to the increasing concern related to its safety in its long-term use and the over prescription of these drugs, new surgical and endoscopic interventions have emerged. A local treatment based on injections of hyaluronic acid, a natural nonimmunogenic mucosal defense, in the lower esophageal mucosa is a tentative treatment option for these patients. Based on this, the investigators pursue to assess the effects of hyaluronic acid in gastroesophageal reflux control.

NCT ID: NCT05542030 Recruiting - Clinical trials for Colorectal Neoplasms

CAD EYE Detection of Remaining Lesions After EMR

Start date: September 12, 2022
Phase: N/A
Study type: Interventional

In the last decade, many innovative systems have been developed to support and improve the diagnosis accuracy during endoscopic studies. CAD-Eye™ (Fujifilm, Tokyo, Japan) is a computer-assisted diagnostic (CADx) system that uses artificial intelligence for the detection and characterization of polyps during colonoscopy. However, the accuracy of CAD-Eye™ in the recognition of remaining lesions after endoscopic mucosal resection (EMR) has not been broadly evaluated. Finally, based on the importance of complete resection of the colonic mucosal lesions, namely suspicious high-grade dysplasia or early invasive cancer, the investigators aimed to assess the accuracy of CAD-Eye™ in the detection of remaining lesions after the procedure.

NCT ID: NCT05474794 Recruiting - Leiomyoma Clinical Trials

Detective Flow Imaging Endoscopic Ultrasonography in Subepithelial Lesions

Start date: July 20, 2022
Phase: N/A
Study type: Interventional

Gastrointestinal stromal tumors (GIST) are the most common malignant subepithelial lesions (SELs) found in the gastrointestinal tract. The diagnosis and differentiation of these lesions from other subepithelial hypoechogenic tumors ( leiomyoma), is important as this may have an impact in the prognosis and treatment of either. Due to GIST's notable features (vascularity and deep location), endoscopic ultrasound (EUS) is the first-line diagnostic approach. Based on this, three models (color-doppler EUS, power-doppler EUS, and e-FLOW EUS), are useful for real-time vascularity detection; however, these modalities are not helpful for fine and slow flow vessel detection. For overcoming this limitation, contrast-enhanced EUS (CE-EUS) is proposed as a first-line approach. Nevertheless, the use of contrast may be harmful, thus limited to some patients. To avoid contrast-related adverse events, a novel diagnostic method known as detective flow imaging endoscopic ultrasonography (DFI-EUS) has emerged. This technique detects fine vessels and slow flow without contrast. Despite the advantages of the latter, few studies have compared it with other diagnostic approaches in the evaluation and differentiation of SELs. Hence, the investigators aim to evaluate the utility of DFI-EUS in the diagnosis of SELs (GIST and leiomyoma) by comparing it with CE-EUS.

NCT ID: NCT05466240 Recruiting - Dengue Fever Clinical Trials

Study of AT-752 in Patients With Dengue Infection

Start date: April 29, 2022
Phase: Phase 2
Study type: Interventional

The Phase 2 study will be conducted in adult patients with confirmed Dengue infection and will investigate safety, PK, and pharmacodynamics (PD) in this population. The study will be conducted in several dosing cohorts to enable dose selection for subsequent trials

NCT ID: NCT05465746 Recruiting - Clinical trials for Arterial Hypertension

Cumulative Blood Pressure Load and Left Ventricular Mass

Start date: July 1, 2022
Study type: Observational

Delay in the diagnosis of systemic arterial hypertension (SAH) causes morbid hypertensive status with target organ damage (TOD). Screening and surveillance of SAH used to be performed through self-measurement of blood pressure (SMBP) or routinary in clinic blood pressure measurement (CBPM). It is essential to determine the correlation between the cumulative blood pressure load through ABPM and the left ventricular mass identified by three-dimensional transthoracic ultrasound (3D-TTE). We postulate a directly proportional and statistically significant association between cumulative blood pressure load and left ventricular mass (LVM).

NCT ID: NCT05453292 Recruiting - Clinical trials for Gastrointestinal Stromal Tumor (GIST)

Endoscopic Ultrasound Radiofrequency Ablation for GISTs

Start date: July 15, 2022
Phase: N/A
Study type: Interventional

Nowadays, for the selection of the treatment for gastrointestinal stromal tumors (GISTs), tumor size, prognosis, resectability and stage should be considered. Due to mutations in KIT and platelet-derived growth factor alpha (PDGFRA) in 90% of patients with this mesenchymal tumor, many tyrosine kinase inhibitors are used. On the other hand, a resectable tumor is approached by surgery, endoscopic and ablation therapy. Radiofrequency ablation (RFA) approach has been studied in hepatic GISTs, and hepatic metastases, but its evaluation in esophageal, gastric, and intestinal GISTs is scarce. This study aims to determine the feasibility, safety and efficacy of endoscopic ultrasound (EUS) guided RFA using the 19 G RFA probe developed by Taewong Medical for the treatment of GISTs.

NCT ID: NCT05387174 Completed - Hypertension Clinical Trials

Nursing Intervention in Two Risk Factors of the Metabolic Syndrome and Quality of Life in the Climacteric Period

Start date: September 4, 2021
Phase: N/A
Study type: Interventional

The estrogenic deficit characteristic of the climacteric stage is accompanied by a high incidence of health problems, such as the presence of Metabolic Syndrome risk factors that contribute to the increase of cardiovascular diseases. Objective: To determine the effect of a nursing intervention based on self-care aimed at improving the control of two metabolic syndrome risk factors (abdominal obesity and arterial hypertension) and health-related quality of life in climacteric women. Material and methods: Quasi-experimental study, non-equivalent control group design with women between 40 and 59 years old who present two risk factors of the Metabolic Syndrome (abdominal obesity and arterial hypertension) from two type C Health Centers of District 17D03 of Quito, Ecuador. Among one of the conceptual hypotheses, the researchers have Conceptual hypothesis 1: Climacteric women of the experimental group after the intervention of Nursing based on self-care improve two risk factors of MS with respect to those of the comparison group. A sample of 40 women was selected for experimental group and 40 for comparison group. Instruments and measurements: Abdominal Circumference, Blood Pressure, Menopause Rating Scale, International Physical Activity Questionnaire (IPAQ). Women in both groups received the usual care and those in the experimental group received a Nursing Intervention with technological support that included individual face-to-face nursing counseling, group education and physical activity sessions through a virtual platform for 12 weeks. Ethical requirements were considered. Expected results: It is expected that after the Nursing Intervention based on self-care the women of the experimental group will decrease the parameters of abdominal circumference, blood pressure and improve health-related quality of life.

NCT ID: NCT05374122 Active, not recruiting - Neoplasms Clinical Trials

AI Guidance for Biopsy in Suspected Cholangiocarcinoma

Start date: May 1, 2022
Phase: N/A
Study type: Interventional

Digital single-operator cholangioscopy (DSOC) has emerged as a medical advance with an important role in the evaluation of indeterminate biliary lesions. This technique has demonstrated higher sensitivity in the guidance for tissue acquisition when compared with standard endoscopic retrograde cholangiopancreatography (ERCP). DSOC-guided biopsy is considered technically safe and successful for tissue collection. Hand in hand with the development of more precise diagnostic techniques, comes the implementation of artificial intelligence (AI) for diagnostic assessment. For the past decade, the role of artificial intelligence (AI) has been increasing at a rapid pace. In the biliary tract, different models have been proposed for the characterization of malignant features. Nevertheless, to date, the discrepancy between the visual impression of the operator and the histological results obtained by cholangioscopy still present, affecting the accuracy the diagnosis. Based on the above, the investigators aim to assess the diagnostic accuracy of AI for the guidance of tissue acquisition with DSOC compared to DSOC without AI for suspected cholangiocarcinoma. As a secondary aim, the investigators pursue to compare quality of AI-guided biopsies samples vs. DSOC biopsies without AI.
