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.
Aim: to compare the effects of single-task (ST) and dual-task (DT) training on physical and cognitive function in institutionalized older adults in 1 month. Methods: Participants were assigned randomly into two groups, ST (multicomponent physical exercise) and DT training (multicomponent physical exercise + cognitive tasks). Both groups performed the exercise three times per week for 1 month. Short Physical Performance Battery (SPPB), handgrip strength, Barthel Index and Montreal Cognitive Assessment (MoCA) were used to assess physical and cognitive performance, respectively. Variables were measured at the beginning (V1),at the end of the exercise (V2), as well as one month later (V3). Paired Student's t-test and lineal logistic regressions models were used to explore the effect of the exercise interventions.
The present study seeks to follow up the cohort of adults representative of Chile's urban population whose levels of chronic pain were evaluated in March 2023 (baseline) as part of the Mental Health Thermometer (MHT) study. The study consists of a 12 month follow-up telephone interview to assess parameters of chronic pain (CP) and subtypes, mental and physical health, lifestyle and adversity and work characteristics. The study objectives are as follows: 1. Estimate the prevalence of CP and subtypes in the general population 2. Explore the association between mental health indicators, perceived work stress and presence of CP in the population. 3. Investigate the impact of CP (functional, occupational and social) among the subset of participants reporting CP 4. Describe the use of management strategies in those who suffer from CP.
The goal of this trial is to assess in healthy subjects between 60 and 70 years the effect of glycemic and glycoxidative postprandial responses and platelet aggregation after intake of bread supplemented with Chilean beans flour when compared with a non supplemented control. The main questions to answer are: - It is possible to decrease postprandial glycemic and glycoxidative responses by means of the intake of bread supplemented with Chilean beans flour when compared to the intake of a control bread non supplemented in healthy elderly persons? - How is affected the platelet aggregation process during postprandial state after intake of bread supplemented with Chilean beans flour, when compared to the intake of a control bread non supplemented in healthy elderly persons? Participants will: - Be characterized by means of: 1) evaluation of body composition, using anthropometric techniques, bioimpedance and 2) biochemical analyses: biochemical profile, lipid profile, serum ferritin, fasting glycemia, HbA1c and insulin. - Arrive at fast to the laboratory and eat randomly control bread, 30% Chilean beans supplemented bread or glucose. Venous blood samples will be taken from the cubital fossa of the dominant arm at: 0, 30, 60 and 120 min postprandial, only after intake of bread control and supplemented bread. In addition, capillary blood will be taken at 0, 15, 30, 60, 90 and 120 min postprandial after intake of glucose, bread control or supplemented bread.
The goal of this study is to evaluate the efficacy, safety, and tolerability of MK-0616 in adult participants with heterozygous familial hypercholesterolemia. The primary hypothesis is that MK-0616 is superior to placebo on mean percent change from baseline in low-density lipoprotein cholesterol (LDL-C) at Week 24.
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by autoantibody production and synovial membrane damage. It significantly impairs overall function and quality of life. Consumption of omega-3 (n-3) polyunsaturated fatty acids (PUFAs) and regular aerobic exercise (AEx) training are reported to have positive effects on the progression of RA. However, the mechanisms behind these benefits are still inconclusive. This study aims to investigate the effects of n-3 PUFA supplementation and AEx training on disease progression, cardiometabolic health, and quality of life, and their association with the plasma and synovial fluid levels of specialized pro-resolving mediators (SPMs) in subjects with RA. The study consists of a 16-week intervention period, during which participants will be randomly assigned in a double-blinded manner to one of four groups: placebo control (PLA), PLA+AEx, n-3, or n-3+AEx. The PLA groups will be given a gelatin-filled capsule, while the n-3 groups will be given n-3 PUFAs equivalent to 2.5 g/d of docosahexaenoic acid and 0.5 g/d of eicosapentaenoic acid. The AEx groups will exercise thrice per week on a stationary electronically braked cycle ergometer at 60-70% of their VO2peak for 50-60 minutes. Before and after the intervention, participants will undergo RA-specific and functional measurements, peak aerobic capacity test, and a dietary and physical activity assessment. Venous blood and synovial fluid from the knee joint will be collected. Changes in disease progression, cardiometabolic health, quality of life, and erythrocyte membrane composition to assess n-3 incorporation, SPM levels, inflammatory markers, and gene expression from blood and synovial fluid will be analyzed. The study aims to elucidate the SPMs that regulate the inflammatory gene expression pathways and associate them with improvements in disease progression, cardiometabolic health, and quality of life after n-3 PUFA supplementation and AEx training.
Due to the COVID-19 pandemic, the world has seen the need to identify groups of patients who experience various effects in the medium and long term after recovering from the initial illness. These medium- and long-term effects are collectively known as the post-COVID-19 condition, Long-COVID, or prolonged COVID. Current evidence indicates, with conservative estimates, that between 10% and 20% of the population could be affected. Its nature is varied and ranges from physical conditions such as chronic fatigue, dyspnea and muscle weakness, to neurocognitive (compromised memory, decreased concentration) and psychological (anxiety, depression, anguish, stress). Early recognition and treatment of this symptom burden is essential for physical recovery and mental health. Due to its multivariate nature, it has been suggested that optimal recovery of patients' quality of life would only be achieved to the extent that their main symptoms are addressed from an interdisciplinary perspective.
This is a multicentre study carried out in participants living with human immunodeficiency virus type 1 (HIV-1) who have not previously been treated with any antiretroviral therapies. The study will investigate two 2-drug regimens for the treatment of HIV-1: a fixed-dose combination oral tablet of dolutegravir/lamivudine (DTG/3TC) and cabotegravir plus rilpivirine long-acting agents (CAB + RPV LA). All participants will initially receive DTG/3TC once daily, and once virologic suppression is attained (plasma HIV-1 <50 c/mL), participants will be offered a choice to switch to CAB + RPV LA or to continue taking oral DTG/3TC. This study will provide important data on the efficacy, safety, implementation effectiveness, and patient-reported outcomes of these two regimens in a study where participants have the option to choose between them based on individual preference. The aim of the study is to evaluate the antiviral effectiveness at 11 months after switching to CAB+RPV LA following initial virologic suppression on DTG/3TC and to provide data on how long it takes participants to suppress their viral load on DTG/3TC.
The purpose of this clinical study is to test the hypothesis that RF vapor ablation of the duodenal mucosa will result in improvement in glycemic parameters, without complications (bleeding/ stricture / perforation). The main aims of the study are : 1. Evaluate the safety of the device and procedure based on the reported adverse events that occur. 2. Evaluate the effectiveness of the device and procedure by comparing change in HbA1c from baseline to 168 days post procedure. 3. Evaluate device tolerability based on pain scores reported by patients. The subject population for this study are adults (18-65 years of age) with type-2 diabetes mellitus. Study participation is 6 months for each patient. The study is comprised of 4 phases: Screening, Run-in, RF Vapor ablation procedure, and Post-vapor ablation follow-up (up to 168 days).
This is a Phase 2 study in adult participants with moderate to severe hidradenitis suppurativa (HS). The purpose of the study is to evaluate the efficacy and safety of SAR442970 compared to placebo.
This study is a substudy being conducted under one pembrolizumab umbrella master study KEYMAKER-U04. The substudy will consist of 2 parts. Part 1 will evaluate the efficacy and safety of coformulated favezelimab/pembrolizumab plus EV and coformulated vibostolimab/pembrolizumab plus EV relative to pembrolizumab plus EV. There will be no comparison of coformulated favezelimab/pembrolizumab plus EV versus coformulated vibostolimab/pembrolizumab plus EV. If ORR and/or DRR are substantially better on coformulated favezelimab/pembrolizumab plus EV and/or coformulated vibostolimab/pembrolizumab plus EV compared with pembrolizumab plus EV, after evaluation of the totality of data, the sponsor might consider Part 2 (expansion) to further characterize the efficacy and safety of the treatment arms under study.
