There are about 1059 clinical studies being (or have been) conducted in Colombia. 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 purpose of this study is to determine the efficacy of pembrolizumab given in combination with either ipilimumab or placebo as first-line treatment in participants with metastatic non-small cell lung cancer (NSCLC). The primary hypothesis of this study is that overall survival (OS) and/or progression-free survival (PFS) is prolonged in participants who receive pembrolizumab and ipilimumab compared to those who receive pembrolizumab and placebo.
High-intensity interval training (HIIT) is currently considered one of the most effective strategies to improved cardiorespiratory fitness, which is recognized as a protective factor for cardiovascular diseases and metabolic diseases such as overweight and obesity. However, current evidence is still limited and requires clarity (frequency, time per session and intensity) regarding to greater increases attributed to HIIT. The aim of this study is to compare the effect of a low-volume high-intensity interval training versus a moderate-intensity continuous exercise on maximal oxygen consumption in overweight women 18 to 44 years old.
This observational study investigates the associations of nutritional indicators, biomarkers, sociodemographic conditions, and infections with child health, as well as physical, behavioral, and cognitive development. Investigators recruited a random sample of 3202 children from primary public schools in Bogota, Colombia in February 2006 and followed them for a median of 6.5 years. Investigators hypothesized that poor nutritional status at the time of recruitment in middle childhood would be related to adverse health outcomes through adolescence.
Non-conspicuous penis (congenital megaprepuce, occult penis) is a symptomatic malformation that includes phimosis and excessively baggy, urine-filled prepuce with alteration of the appearance of the penis. A redundant and enlarged foreskin is the main feature of this entity.This congenital anomaly is difficult to diagnose and may have association with other pathologies such as buried penis. Currently, part of the megaprepuce skin is used to correct the defect. A recent study shows that patients with this pathology and hypospadias present mostly defects in the muscle dartos. The investigators do not know the physiological bases of the megaprepuce, neither the clinical and aesthetics implications of this abnormal tissue for the patient, and how this affects the postoperative evolution. With the present study the investigators intended to answer these questions and to open paths for future research in this area.
The purpose of this study is to evaluate the efficacy of SHP647 as maintenance therapy in participants with moderate to severe ulcerative colitis (UC) who achieved clinical response in induction studies. This is a phase 3, randomized, double-blind, placebo-controlled, parallel-group efficacy and safety study.
The purpose of this study is to evaluate the safety and tolerability of long-term treatment with SHP647 in participants with moderate to severe Ulcerative Colitis (UC).
Asymptomatic bacteriuria (AB) is the isolation of a bacterium in a sample of urine appropriately collected from a person who does not have signs or symptoms of urinary infection. It is common in diabetic women, in pregnant women, in men over 60 years and in patients with spinal cord injury. There is clinical evidence that AB should be treated in patients who will be operated on with urologic surgery because of the risk of presenting infectious complications; however, the timing of initiating antibiotic therapy has not been established, even in some studies the prophylaxis has been considered from one to seven days prior to the procedure, without determining the differences in the outcome for each one of the interventions and causing an undue and risky use of antibiotics. A randomized, parallel-design, single-masked clinical trial will be performed to compare and analysis the bloodstream infections, surgical site infections, readmissions and hospital stay in three intervention groups, 1) those receiving antibiotics during the previous 5 days to the procedure; 2) 3 days prior to the procedure; and 3) those who receive only a single dose of antibiotic on the day of the procedure. The main expected result is to identify the timing of initiation of antibiotic prophylaxis in urological procedures in patients with asymptomatic bacteriuria, with the purpose of diminishing the bloodstream and of the surgical site infections. If it is scientifically demonstrated that those patients who receive a single dose of antibiotic on the same day of the procedure, have the same safety and effectiveness compared to the other two groups, would reduce hospital stay, surgical waiting time and indiscriminate use of antibiotics that generate multidrug-resistant microorganisms, thus generating an impact on Public Health and on the quality of care.
The purpose of this study is to evaluate the efficacy of SHP647 in inducing remission, based on composite score of patient-reported symptoms and centrally read endoscopy, in subjects with moderate to severe ulcerative colitis (UC).
Objective: to compare the changes of the mechanical properties measured by tensile test and three point bending test of two NiTi archwires (heat-activated and superelastic); when exposed to the oral conditions during the first three months of orthodontic treatment and to evaluated their clinical efficacy in lower arch crowding resolution in the anterior mandibular arch. Methods: Randomized clinical trial in 54 orthodontic patients with moderate crowding. They are going to be randomly assigned in to two intervention groups, each group with 27 patients. One group are going to be treated with heat-activated NiTi archwires and the other group with superelastic NiTi archwires. The patients are going to be followed up for three months and cast models will be taken every month. Measures of anterior lower arch crowding resolution are going to be taken by previously-calibrated operators. Six archwires of each group will be chosen at random and will have tensile test and three-point bending test and the mechanical properties are going to measure before and after its clinical use. The outcomes are going to be determined and compared between groups, with correspondent statistical test and the results are going to be analyzed.
This study will investigate BMS-986165 to assess its effects in patients with systemic lupus erythematosus (SLE).
