There are about 10004 clinical studies being (or have been) conducted in Brazil. 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.
International registry on the use of Pentaglobin® in patients with severe bacterial infections; multicentric, international registry, non-interventional trial
This study aims to assess efficacy and safety of Sculptra in the treatment of skin flaccidity in selected areas - arms, anteromedial region, and gluteal regions. To assess the efficacy of Sculptra®, via adapted Global Aesthetic Improvement Scale -GAIS- score determined by blind evaluator, in the treatment of skin flaccidity on the anteromedial region of arm and gluteal region, 4 months after initiating the treatment, based on the assessment of the corporal side randomized to be the first to receive treatment . Considering as an alternative hypothesis of interest a 70% value of the subjects the treated side would have higher GAIS than the untreated side.
This study aims to investigate the role of the left ventrolateral prefrontal cortex (VLPFC) on cognitive reappraisal, using the reinterpretation strategy. For this purpose, we will produce direct disturbance to the activity of this area through anodal and cathodal transcranial direct current stimulation during a reinterpretation task. A double-blind randomized sham-controlled trial will be conducted. 60 healthy volunteers will be allocated into three groups. Each group will receive one type of stimulation (anodal, cathodal or sham) while accomplishing a cognitive task on reinterpretation using images from the International Affective Pictures System (IAPS). The task consists in applying a given emotional regulation condition (downregulate, upregulate or maintain emotions) to a series of images and ranking the intensity of the emotional arousal felt after doing this procedure to each picture. The effects of tDCS on the subjective evaluation of emotional arousal after reinterpretation in each group will be compared.
Background: Lymph node status is an important prognostic parameter in esophageal carcinoma and an independent predictor of survival. Distribution of metastatic lymph nodes may vary with tumor location, tumor histology, tumor invasion depth and neoadjuvant therapy. Surgical strategy depends on the distribution pattern of nodal metastases but consensus on the extent of lymphadenectomy differs worldwide. Especially for adenocarcinoma the distribution of lymph node metastases has not yet been described in large series. Aim of the present study is to evaluate the distribution of lymph node metastases in esophageal carcinoma specimens following transthoracic esophagectomy with at least a 2-field lymphadenectomy. Methods: The TIGER-study is a multinational observational cohort study. All patients with a resectable esophageal or gastro-esophageal junction carcinoma in whom a transthoracic esophagectomy with a 2- or 3-field lymphadenectomy is performed in participating centers will be included. All lymph node stations will be excised and separately sent for pathological examination. Cluster analysis will be performed to identify patterns of metastases in relation to tumor location, tumor histology, tumor invasion depth and neoadjuvant therapy. Conclusion: TIGER will provide a roadmap of the location of lymph node metastases in relation to tumor histology, tumor location, invasion depth, number of lymph nodes and lymph node metastases, pre-operative diagnostics, neo-adjuvant therapy and survival. Patient-tailored treatment can be developed on the basis of these results, such as the the optimal radiation field and extent of lymphadenectomy based on the primary tumor characteristics.
The Health and Education Ministries of Brazil launched the Health in School Program - PSE - in 2007. The purpose of the PSE is twofold: articulate the actions of the education and health systems to identify risk factors and prevent them; and promote the education for health in the public elementary school system. In the health field, the self-regulation (SR) construct can contribute to the understanding of life habits which can affect the improvement of individuals' health. This study aims to present a school-based program, Promotion of Self-Regulation in Health (SRH), which adds the self-regulation approach to the topics of healthy eating and oral health of the PSE for elementary school. A study of a randomized clinical trial enrolling the 5th grade students of public elementary schools from the south of Brazil is presented. The study has two phases. In Phase 1, teachers and health professionals will participate in a training program on SRH, and in Phase 2, they will conduct an intervention in class: Promotion of SRH. The participants were randomly assigned into three groups: Condition I followed the PSE program, Condition II group followed the PSE and the SRH program, and the control group did not enroll in either of the health promotion programs. For the evaluation of the study, the following measures and instruments were applied: Body Mass Index (BMI), Simplified Oral Hygiene Index (OHI-S), Previous Day Food Questionnaire (PFDQ), Declarative Knowledge for Health Instrument, Food Preference Instrument, Student´s Attitudes and Perceptions and Parents Perceptions and Influences on the Health Instrument, Food Availability and Oral Health Instrument, Self-Regulation for Health Scale, Self-Efficacy for Health Scale. Students in the three groups will be assessed five times throughout the year: before the beginning of the intervention program, three months into intervention, six months into intervention, at the end of the intervention, and, finally, six months post intervention to check for the impact of the program on children health.
The study aims at evaluating the effects of an intervention among diabetic women (40 years or older) who belong to the Basic Health Units System (Brazilian public health system). The novelty of this project is that the intervention is low cost and demands very little from the health system in terms of structure, facilities and personnel.
It is a double-blind randomized clinical trial placebo-controlled, which aims to assess whether Domperidone medication helps to increase milk production. The sample of 30 mothers of newborns in the Neonatal Intensive Care Unit of the Hospital de Clínicas de Porto Alegre for at least 15 days, receiving power enteral tube (without clinical condition for oral). Nursing mothers will be evaluated by the researcher (breastfeeding committee member) or consultants in breastfeeding that will advise these women about the practice of runs out of the breasts each mother. You receive containers for collection, at least one for each time you run out. These containers will measure the volume of milk. For each mother that refer insufficient milk production or is not maintaining adequate production for their newborn within 24 hours, one will be generated data form and after 15 days postpartum will be randomized and receive domperidone orally at a dose of 10mg 8/8 hours, or placebo in same volume. The milk volume will be measured daily. Three blood samples will be collected for each lactating each with 5 ml tube without anticoagulant for analysis of serum prolactin and domperidone. The sample 01 will be collected immediately after randomization, before receiving any medication (placebo x domperidone). The sample 02 on 5 of the study. And the sample 03, day 10 of the study, three days after the termination of the use of medication or placebo. A milk sample (5 ml) of each mother will be collected on day 5 to analysis of domperidone levels in milk. Once collected, the samples will be processed and frozen at -80o C for later analysis. All mothers will be followed until hospital discharge of their newborns, to monitor outcome breastfeeding exclusive breast.
There is evidence, of a single randomized controlled trial, that CFT is better than combined manual therapy and motor control exercise for chronic low back pain. However, this study had significant methodological shortcomings regarding the failure to carry out the intention to treat analysis and a considerable loss of follow-up of patients. It is important to replicate this study through a randomized clinical trial with similar objectives in another domain, but correcting these methodological shortcomings. Therefore, the aim of the study is to assess the efficacy of Cognitive Functional Therapy in patients with chronic non specific low back pain.
The purpose of this study is to evaluate the efficacy of pembrolizumab (MK-3745) in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of previously untreated adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma. The primary study hypotheses are that: - Neoadjuvant and adjuvant pembrolizumab plus chemotherapy, followed by adjuvant pembrolizumab is superior to neoadjuvant and adjuvant placebo plus chemotherapy, followed by adjuvant placebo in terms of Event-free Survival (EFS) based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), and - Neoadjuvant pembrolizumab plus chemotherapy is superior to neoadjuvant placebo plus chemotherapy in terms of rate of Pathological Complete Response (pathCR) at the time of surgery. With Amendment 10, upon study completion, participants will be discontinued and may be enrolled in an extension study.
The objective of this study is to evaluate the efficacy of Motivational Interview (MI) on the smoking cessation rates of the smoking groups performed by the primary care teams of the Conceição Hospitalar Group, Porto Alegre, Brasil, and also whether there is an increase in the completion rate of the groups.
