There are about 1829 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.
Background: ICU hospitalization is associated with loss of strength, functionality and delirium. The "Start to Move protocol" demonstrated efficacy in improving and minimizing such effects. Aim: To evaluate the effectiveness of the "Start to move protocol" compared with conventional treatment in ICU subjects on functionality, weakness acquired in the Intensive Care Unit (ICU-AW), incidence of delirium, days of invasive mechanical ventilation (IMV), ICU stay and 28-day mortality. Methods: Randomized controlled clinical trial. Including adults ≥15 years with IMV >48 hours, randomized into Start to move and conventional treatment groups.Functionality, ICU-AW incidence, delirium incidence, IMV days, ICU stay and mortality-28 days were analyzed.
The aim of this study is to evaluate the impact of the third molars in oral health-related quality of life, before and after surgical removal using a validated and frequently used in international investigations instrument (OHIP-14).
This study will evaluate the efficacy, safety, and pharmacokinetics of astegolimab in combination with standard of care chronic obstructive pulmonary disease (COPD) maintenance therapy in patients with COPD who are former or current smokers and have a history of frequent exacerbations.
The purpose of this study is to compare the effect of an early and integral communication strategy (EICS) versus standard care, on the rate of depressive symptoms at 3 months after discharge from the ICU, in patients with severe Covid-19, their family members and health personnel. Evaluating the rate of depressive symptoms at 3 months after discharge from the ICU, with a) Hospital Anxiety and Depression, b) Posttraumatic Stress Disorder Checklist (S)
Carpal tunnel syndrome (CTS) is a compressive peripheral neuropathy, characterized by pain, tingling sensation and paresthesia in the territory of the median nerve, symptoms modulated by psychosocial factors (eg, catastrophic thinking, depression, anxiety). The objective of the study is to determine those psychological and social components that influence the symptoms and function of patients with CTS. An observational cross-sectional design will be performed in patients with CTS. The patients will be selected consecutively in two hospitals of the South East Metropolitan Health Service (Santiago, Chile). The study variables will include: Perception of pain using the Visual Analogue Scale (VAS), the extent of symptoms will be evaluated using the Katz diagram; Functional assessment using the abbreviated version of the Disabilities of the Arm, Shoulder and Hand Questionnaire (QuickDASH); Catastrophic thinking as a response to pain using the Pain Catastrophizing Scale (PCS), fear of movement using the Tampa Scale for Kinesiophobia (TSK-11), and emotional state was assessed using the Hospital Anxiety and Depression Scale (HADS). Both are valid and reliable measures used to evaluate the influence of psychosocial factors in patients with CTS. Individual subject factors including duration of symptoms, type of work (desk / non-desk), BMI, age, gender, educational level and economic income will be collected through an interview process.
Physical activity is a factor that contributes to a motor and cognitive development in early childhood. Currently, childhood obesity has grown steadily in Chile. This study aims to evaluate the impact of a school environmental intervention on the physical activity and cognitive functions in 1st-grade schoolchildren during the COVID-19 pandemic. The study will use a randomized experimental design with a sample of 300 schoolchildren divided into a control and an intervention group (n=150 each group). Sociodemographic characteristics and lifestyle of the schoolchildren will be obtained through a questionnaire answered by parents/guardians. Cognitive function will be evaluated using the TENI test by tablet and physical activity will be measured during 7 consecutive days using accelerometers (Actigraph GT3X and wGT3X-BT). Both groups will receive a lecture aimed at schoolchildren. Teachers of the intervention group will also receive a talk regarding the intervention that will take place in their school environment, which includes a circuit of psychomotor games painted on the recess playground floor. ANCOVA analysis will be performed, adjusted for age and sex; then, a multivariate linear regression model will be applied considering the significant variables and adjustment. The significance level will be p<.05. SPSSv25 and R version 3.14 will be used for the analyses. The intervention is expected to contribute to the increase of physical activity favoring the school environment within a context of vulnerability and with a low-cost initiative
Long-term neurocognitive and psychiatric consequences of COVID-19 remain mostly unknown to date. It has been reported that coronaviruses cause direct central nervous system infection (Needham et al. 2020). Besides that, new or worsening cognitive impairment commonly occurs and persists in survivors of intensive care unit (ICU) stay (Hosey & Needham. 2020). The purpose of our study is to search and describe the cognitive and psychiatric long-term consequences of COVID-19 on patients who have been discharged from critical care units. This is an ambidirectional cohort study, that attempts to follow adults discharged from critical Care Units Adults due to COVID-19 up to 12 months after discharge, to evaluate the presence of cognitive impairment, linguistic and phonation function, depression, fatigue, functional gastroenterological symptoms, anxiety, or post traumatic disorder, and performance in activities of daily living and physical response to exercise as well.
A prospective interventional study is expected to be conducted, to test a possible new treatment for amblyopia (lazy eye syndrome). Bilateral transcranial direct current stimulation (tDCS) is a type of noninvasive brain stimulation, which may help in visual function recovery of adult patients with amblyopia. This pilot study will test the feasibility of said therapy, along with the short term effects of bilateral tDCS in visual function.
Bulk Fill" (RBF) composite resins (RC) has been on the market, with the main advantage of being applied in a single layer, faster and easier than a conventional RC. Repair of RC restorations is a validated treatment option in dentistry, which has been shown to increase the longevity of restorations by minimizing tooth damage such as complete replacement. Currently there are no clinical studies that support the actual performance of RBF repair
Objective: To evaluate the immediate clinical performance using FDI criteria in occlusal and proximal lesions restored with dual polymerization bulkfill composite resin. Materials and methods: Experimental, clinical, controlled, randomized, double-blind study. For the evaluation of Fill-up! (FU) will be clinically compared to the control groups of a conventional Tetric N-Ceram (TB) RBK and Filtek z350 (z350) conventional composite resin. The adhesive process will be carried out under absolute isolation, of selective etching of 37% orthophosphoric acid enamel before applying the respective adhesive according to the trademark of the composite resins. The evaluation will be to 30 days, 6, 12, 18 and 24 months using the modified FDI criteria of postoperative sensitivity, marginal staining, color, marginal adaptation and anatomy, being 1: Excellent, 2: Good, 3: Fair, 4: unsatisfactory and 5: unacceptable. The non-parametric Kruskal Wallis test and Friedman (95% significance) used to compare the criteria.
