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.
Neuroendocrine tumors are rare but recent data showed a relevant increase in its incidence. The Mammalian Target of Rapamycin (mTOR), one of most important area of research, has demonstrated be a therapeutic target in these tumors. The metformin has demonstrate in preclinical studies having an antineoplastic action by inhibiting the mTOR pathway, and may be an alternative treatment for this disease. Eligible patients for this study should have metastatic gastroenteropancreatic neuroendocrine tumors well differentiated (grade 1 or grade 2) and will be treated with metformin 850 mg every 12 hours, and each cycle will consist of 30 days. After 180 days of treatment the efficacy of metformin under the control of disease progression will be evaluated. As a secondary outcome the investigator will check the patient adherence to the treatment, the control of patient symptoms with functioning neuroendocrine tumor, and disease free survival. Also will be performed an analysis of immunohistochemical expression of mTOR pathway proteins of these patients.
Temporomandibular joint dysfunction is described as a multifactorial disease and can be directly linked to other diseases, being of structural factors of the Stomatognathic System or not, such as fibromyalgia. Studies show the interconnection of Temporomandibular Dysfunctions with fibromyalgia. Thus, this project aims to evaluate the effect of Phototherapy on fibromiálgicos patients with temporomandibular dysfunction This is a Randomized, Controlled and double-blind, with the intention to treat. In this way the sample of 61 patients with Fibromyalgia, Temporomandibular joint Dysfunction associated with ages between 35 to 58 years, females who are selected after the inclusion/exclusion criteria, will be randomly distributed in homogeneous groups and the placebo group (P), Phototherapy (FT) group, group of physical activity (A) aerobic and aerobic physical activity + Phototherapy Group (FT + A). Will be used as a means of analysis before and after interventions the following parameters: Pain: clinical evaluation, evaluation of pain by Visual analog scale of pain (EVA), McGill Pain Questionnarire and pressure Algometria. Still we will evaluate the dosage of serotonin, indirectly, by saliva. Quality of life: own illness as questionnaires FIQ (Fibromyalgia Impact Questionnaire), Medical Outcomes Study 36-item Short-Form Health Survey SF-36 and also will assess the quality of sleep, with polysomnography. The treatments will total in 10 sessions held twice a week, and the FT and FT + groups to receive Phototherapy enforcement will be used a portable cluster 9 diodes, where will be delivered 39.3 Joules in tender points of fibromyalgia and TMJ, groups and FT + to carry out aerobic activity in 75% of your MHR for 50 min and the P group will receive the application of Phototherapy of 0 Joules (IE, the equipment does not emit any power). Statistical analysis will be compared using the t test intra-group-Student, one-tail and paired and can be used the Kruskal-Wallis test, the statistical analysis of significance 0.05 for both tests.
This is a phase 3b single arm, open label, multicenter study describing the percentage of time pediatric participants with ITP have a platelet response while receiving romiplostim, defined as a platelet count ≥ 50 x 10^9/L in the absence of ITP rescue medications for the past 4 weeks.
Actinic keratosis (AKs) are premalignant disorders that can evolve into skin cancer. To prevent their development, a study is being conducted with oral isotretinoin and topical tretinoin to verify what drug is the most effective and has the best security profile for these patients. Along with these treatments, cryotherapy with liquid nitrogen and sunscreens will be part of the treatment. The study will have the duration of 10 months. In the first four months, the AKs will be counted and treated with cryotherapy (face and arms) and sunscreens FPS 60 will be used. After it, the patients will return (the AKs will be counted), a new session of cryotherapy will be performed and they will be randomized into two groups: one group using oral isotretinoin 10mg/day ( ISO: 30 patients) and the other one using tretinoin 0,05% cream (AR: 30 patients) applied on face and arms. Skin biopsies will be done for all 60 patients at the beginning of the treatment with retinoids (isotretinoin and tretinoin). After six months of treatment with retinoids, the study will be stopped, AKs will be counted again and skin biopsies will be done. Patients in the group ISO (oral isotretinoin) also have to make blood tests at the beginning, two months and after six months of the treatment. Clinical (AK counting), histological (improvement of parts of the skin) and immunohistochemical parameters will be evaluated to see what drug is more effective for prevention of AKs.
The purpose of this study was to determine whether treatment with tamoxifen or a non-steroidal aromatase inhibitors (NSAI) + goserelin + LEE011 prolonged progression-free survival (PFS) compared to treatment with tamoxifen or a NSAI + goserelin + placebo in premenopausal women with hormone receptor positive (HR+), human epidermal growth factor receptor 2 negative (HER2-) advanced breast cancer.
The purpose of this study is to evaluate the pharmacokinetics (the study of the way a drug enters and leaves the blood and tissues over time) of golimumab administered intravenously (IV) to pediatric participants with polyarticular (affects 5 or more joints) juvenile (an onset before age 16) idiopathic (of unknown cause) arthritis (joint pain) (pJIA) manifested by greater than or equal to (>=) 5 joints with active arthritis despite methotrexate (MTX) therapy for >= 2 months.
This study aims to verify the effects of Thrust Versus Non-thrust Manipulation on Pain, Trunk Proprioception and Postural Stability in Subjects With Chronic Low Back Pain.
This research aims to evaluate the effects of inspiratory muscle training (IMT) on blood pressure, in inspiratory muscle mechanoreflex, autonomic cardiovascular control in subjects with hypertension.
The purpose of this study is to assess the severity of plaque‐type psoriasis (common genetically determined, chronic, inflammatory skin disease characterized by rounded erythematous, dry, scaling patches. The lesions have a predilection for nails, scalp, genitalia, extensor surfaces, and the lumbosacral region) in brazilian participants with chronic plaque-type psoriasis.
The obstructive sleep apnea (OSA) affects between 10% to 25% of the adults. Continuous positive airway pressure (CPAP) is the first choice of treatment in severe OSA. However, the adherence to CPAP varies, and the interface between patient and the CPAP may interfere with adherence, comfort and efficiency as well as in sleep variables. Objectives: (1) to determine if self-reported airflow route (nasal or oronasal airflow) is the same as the route determined in a laboratory analysis in controls (healthy subjects) and severe OSA patients with nasal free airflow of obstruction during asleep and awake, (2) to compare the effects of nasal and oronasal CPAP titration (randomized order of masks, 14 days apart) on apnoea-hypopnoea index, CPAP level, PSG variables - including analysis for body positioning, the airway defense mechanisms (nasal mucociliary clearance, mucus properties, citology and inflammation in nasal lavage fluid) and systemic effects (serum miRNA expression and cytokines), (3) CPAP adherence after 1 month and 12 months.
