There are about 1463 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.
The researchers will conduct a study for avoiding the metabolic syndrome in morbid obese patients. Thus, the aim of the present will be determine the effects of a resistance training programme (RT) in preventing or attenuating metabolic syndrome (MetS) in patients with morbid obesity. A second aim will be report the prevalence of non-responders in terms of improvements in MetS markers and other co-variables considered.
Phase II Clinical Trial to Assess the dose-response and Efficacy of Umbilical Cord-derived Mesenchymal Stromal Cells (MSCs) in Severe Renal Systemic Lupus Erythematosus (SLE).
Exercise training is a cornerstone for the prevention and treatment of metabolic disorders and associated cardiometabolic complications such as type 2 diabetes mellitus (T2D) and hypertension. Similar to the beneficial health effects after performing conventional continuous exercise modalities, high intensity interval training (HIIT) has been reported as an effective alternative exercise-modality to improve glucose homeostasis in both prediabetes subjects and individuals with T2D diagnosed. In this regard, although multiple HIIT-based interventions commonly report acute and long term benefits on body composition, cardiorespiratory fitness and insulin sensitivity in metabolically compromised subjects, little is known about the acute cardiovascular response (i.e., at heart rate level) during HIIT in subjects with different glucose control. HIIT is described as performing brief periods of exercise at vigorous or maximal intensity, interspersed with inactive or low intensity recovery phases of variable duration. In order to characterize different HIIT-based protocols, exercise intensity is usually defined as relative percentages of individual maximal cardiorespiratory fitness (VO2max) or relative maximal power output values. Nevertheless, the need for specific technological equipment to assess these parameters usually limit the prescription and recommendations of HIIT in clinical settings and other public health contexts at massive level. Additionally, the use of self-perceived exertion scales and heart rate (HR) variations upon HIIT have been demonstrating to be accessible and feasible strategies to regulate exercise intensity during HIIT. For example, it was reported that HR and self-perceived exertion scores increased progressively in T2D subjects, parallel to the oxygen consumption rate throughout an acute HIIT session performed on cycle ergometer. Consequently, it is conceivable to hypothesize that determining HR variations during HIIT might optimize the recommendation of this training methodology in metabolically compromised subjects as those at risk or with T2D diagnosed. Therefore, the aim of the present study was To describe and compare the acute heart rate changes in response to an incremental maximal exercise test and a single HIIT session between normoglycaemic (NG), prediabetes (Pre-T2D) and type 2 diabetes mellitus (T2D) subjects.
Gastrectomy is the main treatment for gastric and Siewert type II-III esophagogastric junction (EGJ) cancer. This surgery is associated with significant morbidity. The aim of the present study is to identify the predictors of postoperative morbidity and to evaluate long term survival according to complications. This is a retrospective cohort study.
Randomized, multicentric, prospective, double-blind study: effectiveness of adding allogenic stem cells to a platelet-poor plasma scaffold after arthroscopic debridement and microfractures in patients with osteochondral lesions of the talus Osteochondral lesions of the talus (LOC), affects the ankle cartilage, which it seems to have less repair capacity than that of other joints such as the knee of the hip. The LOC can be an important source of pain and affects comparatively younger, working age and athletically active patients. Although there are several therapeutic strategies, debridement and microfractures performed arthroscopically are the most frequent procedures. After this surgery, it is expected that fibrocartilage will form that covers the osteochondral lesion. Though good results have been reported, this fibrocartilage presents histological characteristics of lower quality to those of the native articular cartilage. Based on previous studies in different joints, it is hypothesized that the augmentation treatment of osteochondral lesions of the talus with mesenchymal allogeneic stromal cells derived from the umbilical cord produces better clinical and imaging results than standard treatment with debridement and microfractures only. Therefore, the present study seeks to compare the effectiveness of traditional debridement and microfracture treatment versus adding a platelet-poor plasma (PPP) scaffold embedded in allogeneic mesenchymal stromal cells derived from the umbilical cord in patients with osteochondral lesions of the talus.
Main Objective of this study is to examine long-term safety of nivolumab in participants on treatment and in follow up.
Education and health are crucial topics for public policies as both largely determine the future wellbeing of the society. Currently, several studies recognize that physical activity (PA) benefits brain health in children. However, most of these studies have not been carried out in developing countries or lack the transference into the education field. The Cogni-Action Project is a crossover-randomized trial. The aim of the study is to determinate the acute effects of three different training sessions consisting in (i) "Moderate-Intensity Continuous Training" (MICT), (ii) "Cooperative High-Intensity Interval Training" (C-HIIT), and (iii) sedentary activity on spontaneous brain activity and neuroelectric indices of cognitive performance during a working memory and a reading task, as measured by electroencephalography (EEG) and eye-tracker. In an energy expenditure counterbalanced fashion, 32 adolescents will randomly undergo each training session , two weeks apart. The main strength of this project is that, to our knowledge, this is the first study analysing the potential influence of PA, sedentarism, and physical fitness on brain structure and function, cognitive performance, and academic achievement in Latin-America and, specifically, in Chile which has been catalogued with an important sociocultural gap. For this purpose, this study will use advanced technologies in neuroimaging (MRI), electrophysiology EEG, and eye-tracking , as well as objective and quality measurements of several physical and cognitive health outcomes.
Despite the evidence and the potential of physical activity related to cognition and academic performance in children, the effects of a before-school physical activity program on these parameters remains unknown.
Objective: The aims of this study will be to detect the fibrocartilage layer (FC) of the human temporomandibular joint (TMJ) using 3D SPGR (Spoiled GRASS sequence) (T1 WATS) sequence and to compare these results with those of conventional magnetic resonance imaging (DP, T2 MRI) sequences in patients with temporomandibular disorders (TMD).
This clinical trial aim to evaluate if the prevention of recurrent cardiovascular events is not inferior in the hybrid mobile and exercise-based cardiac rehabilitation programs in comparison to the standard cardiac rehabilitation program.
