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.

The ancient use of acupuncture as a treatment modality of traditional Chinese medicine has also been proven effective in Western medicine. The use of this treatment tool for pain control is already proven in the literature and today is considered an important adjuvant for this purpose. However, the ancient texts of acupuncture also report the use of certain points to tonify organs functions, despite of pain control. According to these texts there are some points that allow the treatment of lung diseases improving respiratory function. In order to investigate the effects of stimulation of such points using electric field application, the effect of these procedure on pulmonary function and the impact of this practice on dyspnea symptoms, the investigators will conduct a randomized study with 60 patients (1: 1 randomization) distributed in 2 arms (intervention arm-BI and control arm-BC). Transcutaneous neural stimulation of acupuncture points of the BI patients will be performed. For the BC arm the investigators will place the electrodes over the points without turn on the device to produce a placebo effect. Pulmonary function test, Borg scale application and 6 min walk test will be performed before and after the intervention in each group for subsequent data comparison.
Treatment of smoker patients with AgP is considered a challenge to periodontists. To date, only one controlled clinical study (De Genaro Modanese et al., 2016) evaluated the effect of full mouth ultrasonic debridment (FMUD) on smokers with aggressive periodontitis. Its results showed significant improvements in clinical parameters (plaque index PI, bleeding on probing- BoP and probing depth-PD), and immunologic (reductions in interleukin 6- IL-6, tumor necrosis factor- α TNF-α levels), although the results were more favorable for non-smoking patients. Antimicrobials associated to mechanical therapy has been extensively studied (Hafajee et al., 2003, Heitz-Mayfield, 2006). The association of Amoxicillin and Metronidazole have had good clinical and microbiological results in randomized clinical trials in the treatment of AgP (Casarin et al., 2012, Sgolastra et al., 2012, Keestra et al., 2015). Thus, this study investigates clinical, microbiological and immunological influence of smoking in the periodontal debridement associated to Amoxiciclin and Metronidazole of young individuals with pronounced periodontal destruction, compared with non-smokers individuals.
The purpose of the protocol is to assess the longitudinal attainment of person-centered and function related goals of patients who receive AbobotulinumtoxinA (aboBoNT-A) injections for adult lower limb spasticity over a period of 16 months.
The aim of this study is to verify the effectiveness of the association of Shortwave Diathermy and Pilates exercises in patients with chronic non-specific low back pain, on the reduction of pain, functional disability and improvement of the quality of life.
This study will evaluate the performance of the VIDAS® Interferon Gamma (IFN-γ) Release Assay (TB-IGRA) assay, which is intended for use as an aid in the diagnosis of tuberculosis infection. This study is designed to assess (1) the sensitivity of this assay, (2) its percent agreement with other diagnostic tests, (3) its measurement precision , and (4) any potential interference of the presence of other non-tuberculosis mycobacterial bacterial infections with this assay.
The objective of this study will be to evaluate the effect of Antimicrobial Photodynamic Therapy (aPDT) in the Nasal Decolonization of Dialytic Chronic Renal Patients, Staphylococcus Aureus (S.aureus) Carriers This is a 3-months follow-up, randomized, single-blind, prospective controlled trial, single-center and will happen in 02 phases: Phase 1 - Epidemiological Evaluation - A researcher will invite the research participants who are undergoing treatment at the Hemodialysis Service of Clinical Hospital and explain its contents. After reading and signing the informed consent, this same researcher (calibrated for the experiment) will perform nasal secretion microbiological collections to identify patients colonized by S.aureus in the anterior nostril (nasal carrier) - baseline T0 and the application of the questionnaire that identifies possible factors that may be considered as risk for colonization and possible development of diseases related to S. aureus. In the laboratory of Microbiology, the strains will be identified and the colonized patients will be invited to continue the study (Phase 2). Non-carrier patients will only be counseled with infection prevention care. Phase 2 - Parallel clinical trial with two intervention groups (aPDT or Mupirocin) - Patients with nasal aureus (thirty-four colonized patients aged over 18 years) will be treated with aPDT (experimental group) or mupirocin (control group). A trained researcher will collect new aliquots of nasal discharge after completion of nostril treatment (T1) to check for decolonization by culture. A new collection will be performed at 1 (T2) and 3 (T3) months after treatment to assess recolonization. It was evaluated intervention safety (photodynamic therapy) through a directed and open questionnaire about adverse effects.
New therapies for cancer increased patient survival, but led to the recognition of adverse effects associated with cancer treatment, such as the use of chemotherapy. Cardiotoxicity is the most significant adverse effect, which affect the functional capacity and quality of life and is associated with high morbidity and mortality, regardless of the oncological prognosis. One of the manifestations of cardiotoxicity is ventricular dysfunction that can lead to heart failure. Neuro humoral hyperactivation with increased sympathetic nerve activity is a typical manifestation of heart failure and is associated with worse prognosis. Studies have shown that physical training significantly reduces sympathetic nerve activity in addition to improving muscle blood flow, reversing effects on skeletal muscle and improving quality of life. The hypothesis is that physical training may reduce sympathetic nerve activity and vasoconstrictor status in patients with heart failure caused by anthracyclines, as well as improving baroreflex and chemoreflex sensibility, mechanoreflex and metaborreflex control and skeletal myopathy.
Long-acting reversible contraceptives [LARC; copper-intrauterine devices (IUDs), the levonorgestrel-releasing intrauterine system (LNG-IUS) and subdermal implants] are the most effective reversible contraceptives available. A common side effect of these methods is changes in menstrual bleeding. Dissatisfaction with unpredictable bleeding is the main reason for early discontinuation of LARC methods. The mechanism of unpredictable bleeding is unknown; it is likely related to the progestogen dilating superficial veins and capillaries, which are fragile and susceptible to focal bleeding. Other potential influences include changes in structural support of the endometrium, altered matrix metalloproteinase activity, and changes in endometrial perfusion and hemostasis. Local genetic alterations of the hormonal receptors of endometrium can also play a role in the etiology of the unpredictable bleeding experienced by some women. Regarding etonogestrel (ENG)-releasing implant, some evidences suggest that the use of mefenamic acid, mifepristone with estradiol or doxycycline, or doxycycline alone can temporally stop the bleeding; however, all these therapies cannot avert the recurrence of the bleeding. Recently, a randomized clinical trial (RCT) evaluated the effectiveness of a short-term use of combined oral contraceptive (COC) in stopping bleeding episodes and preventing bleeding recurrence. The authors found that bothersome bleeding in ENG-implant users stopped within 14-day of COC treatment, but bleeding most often resumes within 10 days of treatment cessation. Although COC can stop the bleeding, it is not known which component of the COC is responsible for this effect. There is evidence suggesting that estrogen alone is not effective in stopping the bleeding of progestogen-only contraceptives or a high dose of ethinyl estradiol is needed to obtain this effect. Furthermore, the recurrence of the bleeding shown with the COC use could be explained by the interruption of the estrogen. For this reason, our hypothesis is that a progestogen-only pill could be superior to placebo in stopping the bleeding associated with the ENG-implant use as well as being superior to placebo in recurrence of bleeding after discontinuation of the therapy.
