NCT ID: NCT04999774 Not yet recruiting - Strongyloidiasis Clinical Trials

Evaluation of Strongyloidiasis in Ecuador: a fieLd Laboratory Accuracy Study

Start date: September 6, 2021
Study type: Observational

the World Health Organization (WHO) has recently committed to promote the control of strongyloidiasis within 2030 targets for STH control programmes. A specific target is to establish by 2030 an efficient strongyloidiasis control programme in school aged children (SAC), envisaging ivermectin preventive chemotherapy (PC) of SAC at risk of morbidity due to strongyloidiasis. The monitoring of such ambitious PC activity strictly requires appropriate diagnostic tools, but fundamental gaps exist in this field. Indeed, until now at the moment no consensus method for the diagnosis of S. stercoralis infection is recommended and the absence of a gold standard test limits capacity for effective diagnosis, surveillance and disease control. The aim of this project is to provide fundamental information on the performance and applicability of diagnostic methods for the assessment of S. stercoralis infection to inform the forthcoming WHO global strongyloidiasis control program to be implemented as a part of the WHO 2030 disease control targets. ESTRELLA is a cross-sectional study in an area of high prevalence of strongyloidiasis (San Lorenzo, Esmeraldas, Ecuador). The study will have a school-based approach, and each enrolled SAC will be asked to supply fecal and blood samples for testing with different methods for the diagnosis of S. stercoralis infection.

NCT ID: NCT04915833 Recruiting - Clinical trials for Colorectal Neoplasms

Computer-aided Detection During Screening Colonoscopy (Experts)

Start date: April 26, 2021
Phase: N/A
Study type: Interventional

Evaluation of the colonic mucosa with a high definition colonoscope (EPKi7010 video processor). The endoscopy images will be seen on a 27inch, flat-panel, high-definition LCD monitor (Radianceā„¢ ultraSC-WU27-G1520 model) only by one expert endoscopist, randomly assigned. The number, location, and polyps' features (Paris classification) will be recorded by the operator. If a polyp is detected, the endoscopist will remove the polyp endoscopically with a cold snare. The same patient will be submitted to a second, the same session, computed aided real-time colonoscopy using the DISCOVERY, AI-assisted polyp detector. Colonoscopy will be performed by a same-level-of-expertise operator in comparison to the initial procedure. Any polyp or lesion detected with the AI system will be recorded and endoscopically removed and considered as a missed lesion from standard colonoscopy.

A randomized, double-blind, placebo-controlled international multicenter clinical trial design will be adopted. A total of 29,000 subjects aged 18 years and above are planned to be recruited, including 750 subjects aged 18-59 years and 250 subjects aged 60 years and above in China; 21,000 subjects aged 18-59 years and 7,000 subjects aged 60 years and above will be recruited outside China. Safety and immunogenicity will be evaluated among the Chinese subjects, and efficacy, immunogenicity and safety will be evaluated among the subjects outside China. Among them, 750 subjects aged 18-59 and 250 subjects aged 60 and above from outside China and all subjects from China will be selected as the immunogenicity subgroup for immunogenicity bridging study. The IgG levels of SARS-COV-2 neutralizing antibody and RBD protein binding antibody will be detected by blood sampling before vaccination, 14 days and 6 months after full course of vaccination to evaluate the immunogenicity and immune persistence.

NCT ID: NCT04644055 Recruiting - Liver Cirrhosis Clinical Trials

EUS Share-wave in Patients With Liver Cirrhosis

Start date: November 1, 2020
Study type: Observational

Patients with chronic liver disease may develop progressive hepatic fibrosis. Liver cirrhosis should be detected at the early stages in order to avoid the complications related to these two conditions. The diagnostic work-up of patients with chronic liver disease includes less-invasive diagnostic methods such as abdominal ultrasonography, transient elastography, upper endoscopy; and more invasive procedures, mainly liver biopsy and portal pressure gradient measurement, both with associated risks. Endoscopic ultrasound offers a benefit of including all diagnostic work-up in a single procedure. The investigators previously demonstrated that EUS-elastography of the liver and spleen is reliable marker for predicting liver cirrhosis. Recently, a quantitative evaluation of fibrosis using share wave elastography was introduced, mainly for the pancreatic tumor fibrosis measurement (2). Elastography measures the elasticity of tissues (hardness); whereas share wave measures the tissue elasticity as the elastic modulus by measuring the share wave velocity. Share wave measurement will be performed with the Arietta 850 Endoscopic ultrasound console using a linear ultrasound video gastroscope EUS-J10 (Pentax Medical, Hoya Corp, Japan). The investigators proposed the EUS-share wave of the liver as a reliable diagnostic marker in patients with liver cirrhosis.

NCT ID: NCT04596345 Recruiting - Clinical trials for Psychological Distress

Psychological Distress in Emerging Adulthood: A Longitudinal Study

Start date: October 15, 2020
Study type: Observational

Emerging adulthood (18-29 years) is a critical stage in lifespan development. During this stage, people experience instability: shifts from their families of origin, breakups of relationships and job changes are frequent before most young adults stabilize their lives and make more lasting decisions. This study seeks to understand the psychological distress of emerging adults in Quito, Ecuador and define how it varies over a year.

NCT ID: NCT04592263 Active, not recruiting - Clinical trials for Patient Satisfaction

Patient Centered Care in Diabetes in Ecuador

Start date: August 1, 2019
Study type: Observational

Introduction: According to World Health Organization data, it is estimated that more than 422 million people have diabetes. In Ecuador, diabetes is the second cause of death, only after ischemic heart disease, and is the first chronic non-communicable disease. The complexity of the pathology, its difficult management and the patient's commitment and involvement in their own care has led health systems to seek mechanisms to activate patients. Currently, tools have been developed, Patient Reported Experience Measures (PREM) and Patient Reported Outcome Measures (PROM), which seek to reduce this gap between patient and health system. Objectives: To develop and validate PREM and PROM tools for diabetes in the Ecuadorian context. To achieve better clinical results and greater patient satisfaction with the system, thus adding value to the care process of patients with diabetes. Method: This is a study with two components. The first component will focus on the design and validation of PREM and PROM tools in Ecuador. A second component, consisting of a prospective cohort study for the corresponding implementation of the questionnaires obtained and their validation. Expected results: It is expected to involve patients in the care process, thus establishing a framework for achieving better clinical outcomes and greater patient satisfaction with the system.

NCT ID: NCT04560062 Recruiting - Clinical trials for Diabetes Mellitus, Type 2

Contextualizing the Evidence for Action on Diabetes - Cohort

Start date: October 13, 2020
Study type: Observational

This protocol reflects the second part of a larger mixed-methods study aimed at exploring the process by which global recommendations can be translated into context-specific, evidence-informed action for diabetes prevention in low-resource settings. Firstly, a retrospective cohort study will assess the current level of implementation of comprehensive diabetes care over a 24-month period (2019-2020), by describing healthcare received and health outcomes of a representative sample of diabetes patients currently accessing care in the study region. Focus groups prompted by the findings of the retrospective study will be used to inspire local innovations which will be evaluated through a prospective follow-up of the cohort.

NCT ID: NCT04486404 Enrolling by invitation - Clinical trials for Acute Stress Disorder

Needs, Perceptions and Acute Stress of Healtcare Workers Caring for COVID-19 Patients in South America

Start date: April 1, 2020
Study type: Observational

The pressure on care and the demand for critical decision-making generated by the current SARS-CoV-2 (COVID-19) pandemic, together with the situation of extreme social alarm and the adverse conditions in which care work must be promoted at this time, draw an extreme scenario in which action is urgently needed to alleviate emotional overload, acute stress reactions and other affective pathologies or psychosomatic reactions that may eventually lead to post-traumatic stress situations. This eventuality is being observed massively among professionals from different groups and levels of responsibility. In the case of healthcare personnel, it should be added that the care of non-COVID19 patients (of all pathologies and conditions) is clearly compromised and it is up to the professionals as a whole to make critical decisions and exercise a professional practice that is radically different from what has usually been done, which may require the application of undesirable triage criteria that are difficult for everyone to assume. Healthcare professionals and other essential personnel for healthcare and social-healthcare work (including personnel from external companies) are being subjected to emotional tensions and extraordinary, high-intensity work demands. Without professionals who feel supported and with moral strength, care will be even more compromised. The current scenario makes us think of many critical situations that are occurring as a result of the overload experienced. It is essential to act in order to counteract the devastating effect of this health crisis on health professionals and those who support them in their care work.
