There are about 59 clinical studies being (or have been) conducted in Uruguay. 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 randomised controlled trial compares the immediate dentoalveolar restoration and bovine demineralised bone in immediate implants placed in fresh sockets with buccal resorption. A total of 34 patients will be included and followed clinically and radiographically for 18 months. Patient centred outcomes will also be evaluated.
This study evaluates the impact of the treatment with L-Carnitine on the function of adults over 65 years, in conjunction with regular exercise. Simple randomization will be performed, distributing patients in 3 treatment groups, with L-Carnitine or Placebo, and with physical exercise at home or supervised.
This is a multi-country, multicentre, observational prospective data collection cross sectional study of patients with stable COPD in Latin America. Primary objective is to assess and characterize COPD symptoms over a period of 24 hours, by collecting information about the respiratory symptoms experienced at different times of the day and night-time in patients with stable COPD under real clinical practice conditions. Correlation between each of these symptoms and the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification, adherence to respiratory treatment, level of dyspnea, disease severity, comorbidities and physical activity as well direct costs will be done as secondary objectives. Study population are patients of 40 years and older, smokers or ex smokers of >= 10 pack/years with previous COPD diagnosis, attending outpatient specialists consults in Argentina, Chile, Colombia, Uruguay, Costa Rica, Guatemala and Mexico. Sample size is targeted to 900 enroled patients in order to ensure 860 patients to achieve statistical power to primary objective.
The aim of the study is to test whether a resource-sparing 4-week, 20-fraction course of accelerated hypofractionated radiotherapy is non-inferior to accelerated radiotherapy delivering 33 fractions over 5.5 weeks in the treatment of patients with Stage I-IV squamous cell carcinoma of the pharynx, larynx and oral cavity with the exception of paranasal sinus, nasopharyngeal and stage I-II glottic carcinomas.
The proportion of hypertensive patients achieving adequate blood pressure control meeting guideline targets remains low. Of those patients on blood pressure lowering drugs, only 50% reach control. Objectives: 1. Test the feasibility of telemonitoring of blood pressure in uncontrolled hypertensive patients. 2. Investigate whether telemonitoring enabled self-measurement of blood pressure leads to faster blood pressure control than self-measurement without telemonitoring. 3. Secondary endpoints include adverse effects, assessment of quality of life, adherence, a log of technical problems, and cost-effectiveness. Methods: Randomised parallel-group study consisting of 4 stages. - Screening to check for eligibility. - Randomisation in a 1:1 proportion to control or experimental arm: In the control arm, doctors will receive reports on the self-measured blood pressure based on diary cards; in the experimental group, doctors will receive weekly reports via telemonitoring. - Treatment period: Doctors will adjust treatment according to the present guidelines of Hypertension. Blood pressure control is a home blood pressure below 135 mm Hg systolic and 85 mm Hg diastolic. Once blood pressure control is achieved the treatment period ends. - Late follow-up: Assessment of blood pressure control at home 3 months after completion of the treatment period by means of telemonitoring. Sample size: 120 patients per group. Patients: recruited at clinics from Uruguay and Argentina. Main Inclusion Criteria: - Women and men, age range 20 to 80 years. - Uncontrolled hypertension and new diagnosed hypertension with a self-measured blood pressure at home of 135 mm Hg systolic and/or 85 mm Hg diastolic or more; - Patients should be willing to accept adherence checking during follow-up and sign an informed written consent. Exclusion Criteria - Patients emotionally or intellectually not capable of measuring their blood pressure at home; - A clinical or social context, which is suboptimal for the self-measurement of blood pressure; - Pregnancy; - Alcohol or substance abuse or psychiatric illnesses; - Participation in another study. Expected outcomes: blood pressure control will be achieved faster in the telemonitoring group.
The purpose of this study is to examine the association between maternal alcohol use and newborn phosphatidylethanol (PEth) levels in their newborn.
The RELAHP registry is a Latin-American multinational, multicenter, prospective observational registry-type cohort study, which pretends to identify clinical characteristics, clinical course, management and outcome of all forms of pulmonary hypertension (PH). All consecutively consented patients newly diagnosed with WHO Group I-V PH according to specific hemodynamic criteria on right heart catheterization at the participating centers will be enrolled. Patients will be followed six-monthly for a minimum of five years from the time of enrollment.
This study will evaluate the efficacy and safety of oral capecitabine (Xeloda) versus 5-fluorouracil (5-FU), in combination with intravenous (IV) cisplatin, in participants with advanced and/or metastatic gastric cancer. The anticipated time on study treatment is at least 6 weeks and continued up to disease progression, and the target sample size is 300 individuals.
This is a descriptive, prospective, observational and epidemiological study on participants recently diagnosed with breast cancer to evaluate the human epidermal growth factor receptor 2 (HER2) status by immunohistochemistry (IHC) and silver in-situ hybridization (SISH) procedures.
Background: - Researchers want to learn more about breast cancer in Latin American women. They also want to learn how and why women respond differently to standard treatment. Tissue and blood samples from women with breast cancer are needed to study this disease in order to find new ways to prevent, diagnose, and treat it. Objective: - To learn more about the biology and genetics of breast cancer in Latin American women. Eligibility: - Latin American women age 18 and older of all ethnic backgrounds who have clinical stage II or III breast cancer. They must still be active and able to self-care. Design: - Participants are only agreeing to have extra tissue or blood samples collected. They are also letting tissue left over from surgery be used for research. No procedures outside of standard care will be done. - Participants may have a medical history, physical exam, and blood tests. They may have a pregnancy test. They may have an ultrasound, mammogram, and other scans. They may have an intravenous needle placed in an arm vein. - Participants may have a core biopsy. For this, a needle is inserted into the breast. A piece of tissue is extracted. - Participants who have chemotherapy may have blood taken after treatment/before surgery. Tissue may also be collected. - Participants will complete a questionnaire. It will ask about their social and economic background. It will ask about their family history of cancer. It will also ask about access to diagnosis and treatment of breast cancer. - Participants may be followed for up to 5 years.
