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.
This project aims to improve adherence rate through pharmaceutical care in patients with systemic lupus erythematosus (SLE) to help achieving therapeutic goals and finally to improve the quality of life of these patients.
Randomized trial aiming to investigate the effectiveness of a lifestyle intervention program implemented within the first year after a pregnancy complicated by gestational diabetes (GDM), in delaying or preventing the development of type 2 diabetes.
The dependence on tobacco is a predictable leading cause of death. The treatment based on the cognitive-behavioral therapy, including relapse prevention, became standard for tobacco dependents; yet scientific advances are still needed. Accordingly, the Mindfulness-Based Relapse Prevention (MBRP) program, adjunct to treatment, has shown promising results. The purpose of this project is to evaluate the effectiveness of the program MBRP as an adjunct in the treatment of smoking cessation instituted by the Ministry of Health, through the Instituto Nacional do Câncer (INCA) in Brazil.There will be a randomized clinical trial, with a simple random allocation. 60 patients will participate in this study receiving treatment (INCA'S standard) randomized between two groups: the MBRP Group (EG), which will undergo eight sessions of MBRP; and the Control Group (CG) that will undergo eight sessions of the traditional model of Relapse Prevention.This study will be conducted at Ambulatory benchmark to smoking cessation treatment in the city of Juiz de Fora (Minas Gerais State- Brazil). Changes will be evaluated on several variables such as cessation of smoking, anxiety, depression, craving, positive and negative affects and will investigate the association of levels of mindfulness with smoking cessation. The data will be assessed at baseline (T0) and four other times: 1 (T1), 3 (T2), 6 (T3) and 12 months (T4) after the initiation of the study, besides being subjected to evaluations of regularly planned maintenance in the protocol of Ministry of Health. For data analysis there will be used Analysis of Variance with Repeated Measures and Longitudinal Logistic Regression, in order to evaluate the effect of two types of intervention on the evolution of comorbidities and abstinence of patients.
One of the most challenging issues of chronic Chagas disease is to provide earlier detection of heart involvement. Two-dimensional speckle tracking (2-D ST) echocardiography, a new imaging modality with useful applications in several cardiac diseases, has been validated for subjects with myocardial infarction against cardiac magnetic resonance (CMR). Here the investigators hypothesize that the longitudinal global strain (LGS) has an incremental value to ejection fraction for predicting myocardial fibrosis in subjects with Chagas disease.
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.
Tuberous Sclerosis Complex (TSC) is a multisystemic autosomal dominant disease that is characterized by the development of benign neoplasms in brain, kidney, lung, skin and heart. TSC is caused by mutations in TSC1 and/or TSC2 genes, which encode, respectively, hamartin and tuberin, that are involved in the regulation of cell proliferation, cell cycle and protein synthesis. Most patients exhibit dermatological, renal, neurological and pulmonary (lymphangioleiomyomatosis, LAM) manifestations. Neurological involvement include subependymal nodules, subependymal giant cell astrocytomas and cortical tubers. LAM is characterized by the proliferation of LAM cells around the airways, blood vessels and lymphatics, which result in vascular and airway obstruction and cyst formation. The most frequent TSC manifestation in the kidney is the development of angiomyolipomas (AML). Dermatologic lesions represent the most common manifestations of TSC, mainly hypomelanotic macules and facial angiofibromas. The most significant functional implication of the tuberin-hamartin complex is its regulatory role upon the mammalian target of rapamycin (mTOR) pathway. Mutations in TSC1 or TSC2 lead to increased mTOR activity and favor tumor development and growth. All lesions associated with TSC, sporadic LAM and sporadic AML share a common molecular pathogenesis, based on TSC1/TSC2 mutations and mTOR hyperactivity. Up to date, TSC patients have been followed in separated medical services in our institution, according to their predominant phenotype. The current knowledge, however, suggest that the ideal follow up of such patients should be conducted in an integrated fashion among the specialties associated with the main disease manifestations. Experts in TSC from each of these areas have recently created a TSC/LAM/AML integrated program in the University of São Paulo Medical Center, and his project will be initiated with the generation of an integrated TSC/LAM/AML registry, which intends not only to clinically characterize this patient population but also to document the employed treatment modalities. Once this first goal is achieved, clinical trials are planned to be performed. The central aim of this observational study is to clinically characterize the TSC/LAM/AML subject population followed and referred to the University of São Paulo Medical Center. Specific aims: To characterize the pulmonary, the neurological, the renal and the dermatologic phenotypes of this patient population.
Sleep apnea involves significant increases in disease and death, but its consequences in people over 65 years of age are incompletely recognized. Intraoral mandibular advancement appliances reduce the number of apneas and hypopneas. The investigators hypothesized that oral appliances provided to the elderly may prevent hypertension and other consequences of sleep apnea in large populations, at a favorable cost/benefit relationship for the public health system.
Objective: To evaluate the correlation / association between inflammatory ultrasonography findings and clinical /functional assessment in symptomatic hand OA interphalangeal joints (IP). To evaluate the intra and interobserver reproducibility of ultrasound findings. Methods: It was conducted a prospective study in 60 symptomatic hand OA patients. They were assessed in six times (T0, T1, T4, T8, T12 and T48 weeks) by "blind" observers (clinical and ultrasonography). The intra and interobserver reproducibility analysis was performed in 25% of the sample. Differences were considered as statistically significant when p< 0.05.
Cerebral Palsy induces oral alterations that impact on oral health, requiring dental treatment. The objective of this study was to evaluate the use of conscious sedation with nitrous oxide (N2O) in the control of stress during dental treatment in individuals with Cerebral Palsy.
