There are about 2320 clinical studies being (or have been) conducted in Chile. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This study have as primary aim "To compare the H. pylori eradication rate between the quadruple bismuth therapy versus the standard triple therapy recommended by the AUGE Clinical Guidelines for Helicobacter pylori eradication treatment in peptic ulcer patients." Briefly, this is a randomized, multicenter, controlled, double-blind clinical trial with two parallel arms. The control group will receive the current Standard Triple Therapy for the eradication of H. pylori. It consists of omeprazole + amoxicillin + clarithromycin for 14 days. The intervention group will be administered Quadruple Therapy with Bismuth, which consists in esomeprazole + amoxicillin + metronidazole + bismuth subsalicylate for 14 days
An upper digestive endoscopy diagnostic procedure is undoubtedly a situation that will generate anxiety. The environment, protocols, distance the patient from the family member or partner, which is perceived as a threat to integrity. The objective of the study is to determine the effectiveness of a structured, significant follow-up nursing intervention to reduce anxiety in patients who are going to undergo upper digestive endoscopy in a public hospital in the Biobío Region, year 2021. The methodological proposal will be in a randomized, single-blind, third-party evaluation clinical trial, the intervention will consist of the visual and tactile presence of a significant companion throughout the endoscopic procedure. The sample will be 126 that will make up the experimental and control group. It is hypothesized that patients who have a significant follow-up will obtain 10 points less on the anxiety scale compared to those who did not have the intervention. The data will be collected with the Spielberg state / anxiety test (STAIT) and the Visual Analog Scale (VAS) to measure psychological effects, with vital parameters (pressure, pulse, respiration, saturometry), physiological effects, as well as the effects biochemicals with blood levels of potassium, glycemia and cortisol in saliva and mechanical effects through the monitoring of movements, using a mesh of pressure sensors. The difference-in-difference statistical method will be applied by t student, to analyze the data. The requirements of Emmanuel will be applied to safeguard the ethics of the study. It is hoped that significant follow-up as a nursing intervention will be shown to reduce the anxiety of the patient who is going to undergo an endoscopic procedure.
The following study seeks to provide information regarding to the RobHand exoskeleton for hand neuromotor maintenance and/or rehabilitation, developed by the University of Valladolid, Spain.
Phase 2 clinical trial in adults previously vaccinated against SARS-CoV-2 in Chile with an initial schedule of two doses of CoronaVac® plus two booster doses with different vaccines. Subjects will randomly receive a third booster dose with Omicron, trivalent, or CoronaVac® vaccine. The humoral immunogenicity against COVID-19 will be compared in subjects that received the Omicron or the Trivalent vaccines with subjects that received CoronaVac® to determine the superiority of the two candidate vaccines versus CoronaVac®. Subjects will be followed for 6 months after the booster dose administration.
The high-flow nasal cannula (HFNC) has increased its evidence in patients during pulmonary rehabilitation. These studies hypothesize that the physiological effects of HFNC (positive expiratory pressure, anatomical dead space lavage, thermo-humidification) lead to an increase in exercise time. This is believed to be due to improvements that the device can generate in the respiratory system and muscles. However, the physiological effects of HFNC on respiratory effort and distribution of pulmonary ventilation during exercise are unknown. The aim of this study is to determine the acute effect of high flow nasal cannula on the distribution of pulmonary ventilation and respiratory effort during physical exercise in healthy subjects.
This is a Phase 3, randomized, observer-blinded study to evaluate the efficacy, safety, tolerability, and immunogenicity of a single dose of a quadrivalent influenza modRNA vaccine compared to licensed inactivated influenza vaccine in healthy adults 18 years of age and older.
This study is testing the safety and tolerability of subcutaneous semaglutide in participants with type 2 diabetes (T2D) in Chile. Participants will get a once-weekly subcutaneous injection of semaglutide in doses decided by the study doctor's criteria, according to participant's personal needs. The study will last for about 24 weeks. Participants will have 4 clinic visits and 2 phone calls. Participants will have 3 laboratory tests during the study (blood and urine samples).
The purpose of this study is to assess the protection of smallpox preexposure vaccination against infection with mpox in real-world individuals with risk factors for mpox.
Periodontitis is a prevalent inflammatory condition that destroys tooth-supporting structures. This condition is associated with pro-inflammatory mediators that utilize STAT3 as an activator of specific genes related to inflammation and tissue destruction. STAT3 has not been studied in the context of periodontitis in humans. We propose that STAT3 is associated with periodontitis. This knowledge might help to further our understanding of periodontitis pathology
A quasi-experimental study developed in sedentary morbidly obese men and women (age 43.6±11.3 y; body mass index [BMI] ≥40 kg/m2) were assigned to a CT group of ET plus RT (ET+RT; n=19; BMI 47.8±16.7) or RT plus ET order group (RT+ET; n=17; BMI 43.0±8.0). Subjects of both groups received eight exercise sessions over four weeks. Systolic (SBP), diastolic (DBP), mean arterial pressure [MAP], heart rate at rest [HR], and pulse pressure [PP] measurements before and after 10 minutes postexercise. Secondary outcomes were other anthropometric, body composition, metabolic, and physical condition parameters. Using the ∆SBP reduction, and quartile categorization (Q) in 'high' (Rs: quartile 4), 'moderate' (MRs: quartile 3), 'low' (LRs: quartile 2), and 'nonresponders' (NRs: quartile 1) were reported.
