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.
Background: Muscle atrophy and reduced leg strength are related to exercise intolerance in patients with intermittent claudication (IC), suggesting that strength training (ST) could improve exercise performance in these patients. Objective: Analyze the effects of ST in walking capacity in patients with IC comparing with walking training (WT) effects. Intervention: Patients were randomized into ST and WT. Both groups trained twice a week, for 12 weeks, at the same rate of perceived exertion. ST consisted of 3 sets of 10 repetitions of whole body exercises. WT consisted of 15 two-minute bouts of walking intercalated with 2 minutes of resting. Measurements: Walking capacity, peak VO2, walking economy, ankle brachial index, ischemic window and knee extension strength
The purpose of this study is to evaluate the effects of a Zen meditation retreat (Sesshin) on psychophysiological parameters in healthy volunteers (regular meditators and non-meditators) and in cancer patients and to observe possible changes in the attentional circuitry (through functional Magnetic Resonance Imaging- fMRI) and in psychological tests (Beck Anxiety and Depression Inventories, Self-Compassion Scale, Mindfulness Attention Awareness Scale, Lipp Stress Scale for Adults).
The purpose of this study is to investigate whether neratinib can further reduce the risk of recurrence from previously diagnosed HER-2 positive breast cancer after adjuvant treatment with trastuzumab.
The primary objective of the study is to compare the complete response (CR) rate of bendamustine and rituximab (BR) with that of standard treatment regimens of either rituximab, cyclophosphamide, vincristine, and prednisone (R-CVP) or rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with advanced, indolent non-Hodgkin's lymphoma (NHL) or mantle cell lymphoma (MCL).
The purpose of this study is to determine if differences in the design of multifocal intra-ocular lenses would mean different values of higher-order aberrations and different performance in objective parameters such as modulation transfer function.
Radiation therapy (RT) has been a component of breast cancer treatment for almost 100 years. Although initially used for the treatment of chest wall recurrences after mastectomy and for advanced inoperable disease, RT has evolved into a critical component of early therapy for women with an intact breast following lumpectomy and for mastectomized women who are at high risk for local failure. Currently breast cancer patients need a multidisciplinary management including surgery, chemotherapy and radiotherapy, radiotherapy has a significant role in loco regional control of the disease. It is estimated that 87% of these women will develop some degree of radiation-induced dermatitis, varying from mild to brisk erythema or even moist desquamation. Topical agents, such as corticosteroid creams and other products including Aquaphor (Beirsdorf Inc, Wilton, CT), and trolamine (Biafine; Genmedix Ltd, France), are commonly prescribed at the onset of radiation dermatitis or, in some institutions, at the beginning of radiotherapy. The aim of this randomized phase III study was to assess the effectiveness of aloe vera cream for the prevention of acute radiation-induced dermatitis of grade 2 or higher during postoperative radiotherapy for breast cancer, compared to best supportive care. The secondary objectives were to assess pain, treatment interruption as a result of skin reactions, and the quantity of life during the treatment.
The purpose of this study is to assess the long-term safety and effectiveness of botulinum toxin type A on patients with overactive bladder as a result of spinal cord injury or multiple sclerosis. This is a follow-up study to two Allergan sponsored studies (NCT00311376 and NCT00461292).
The purpose of this Phase III study was to confirm the value of adding everolimus to weekly paclitaxel and trastuzumab as treatment of HER2-overexpressing metastatic breast cancer.
The aim of this study was to investigate the buffering effect of a calcium glycerophosphate-fluoride (CaGP-F) dentifrice on in vivo dental biofilm after a cariogenic challenge and evaluate its probable 12-hour protective effect. Twelve young adults took part in this randomized, double blind, 14-day 4-phase crossover study. Between each phase, the volunteers had a 1-week wash-out period. Coded dentifrices were randomly assigned to the volunteers: A) no F and no CaGP; B) CaGP-only (0.13%); C) F-only (1500 ppm (ppm= parts per million of fluoride which is equivalent to mg/kg)); D) CaGP-F (0.13%, 1500 ppm, respectively). The pH measurements were taken from a single-site using a microelectrode, with salt bridge established by a 1M KCl (one molar potassium chloride) solution with a reference electrode. pH measurements were taken at 0 (baseline), 1, 7, 14 and 21 min (minutes) after a cariogenic challenge (10% w/v sucrose solution, %w/v = percent weight per volume). Four sets of measurements were carried out: (D0BS) before test dentifrice usage; (D01min) 1-min after test dentifrice usage; and (D712h) 7 days and (D1412h) 14 days using the test dentifrice, 12 hours (h)after brushing. Stephen curves and mean AUC (area under the curve) were obtained.
The study consists of evaluating the efficacy of an Educational Program for prevention of occupational musculoskeletal problems in workers. It is a randomized clinical trial with parallel groups and blinded evaluator, with a control group not submitted to the educational program, but that received a program for general orientation in health. The primary outcome was the change of the quality of life measured by means of Medical Outcomes Study 36-Term Short Health Survey (SF-36), that it is a generic instrument of evaluation of the quality of life, translated and validated in Portuguese of Brazil.
