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 randomized trial is set out to compare the postoperative strength preservation capacity of local infiltration anesthesia (LIA) and pericapsular nerve group (PENG) block after performing a primary total hip arthroplasty (THA). The hypothesis is that LIA represents a superior alternative to PENG block in terms of strength preservation but providing effective analgesia during the first 24 postoperative hours after THA. Hence, the trial was designed as a superiority study hypothesizing a fivefold reduction in quadriceps paresis/paralysis at 3 hours.
This study is a multi-center, randomized, double-blind, parallel, placebo-controlled, phase III clinical trial to evaluate efficacy and safety of pyramax in mild to moderate COVID-19 patients.
This is a longitudinal study of participants from two university communities in Chile. The primary objective is to examine the effect of a regional lockdown on alcohol and tobacco use, using a difference-in-difference analysis to obtain causal estimates of these COVID-19 policies.
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).
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.
This was a parallel treatment, Phase 2, double-blind, 2-arm, placebo-controlled study with 2 staggered cohorts (2 arms in each cohort) to evaluate the efficacy and safety of rilzabrutinib in adult participants (aged at least 18 years) with moderate-to-severe AD and intolerance or inadequate response to topical corticosteroids (TCS). The total study duration per participant was expected to be approximately 21 weeks, including up to 4 weeks of screening, 16 weeks of on-treatment double-blind period, 1 week of post-treatment follow-up.
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.
