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.
Dental materials with antibacterial properties can prevent the harmful effects caused by oral cariogenic bacteria. This double-blind controlled clinical trial evaluated the performance of antibacterial cement for sealing infected dentin in atraumatic restorations of primary molars.
The purpose of this study is to explore the efficacy of paliperidone palmitate administered as a once monthly injection in patients with an acute exacerbation of schizophrenia.
The purpose of this study is to determine whether a loading dose of atorvastatin before percutaneous intervention procedures in acute coronary syndromes is effective to reduce major cardiovascular events(MACE).
Light-emitting diodes (LEDs) have been used to minimize muscle fatigue in athletes and healthy subjects. Patients with chronic obstructive pulmonary disease (COPD) are susceptible to early muscle fatigue. The objective of this study is to assess the acute effects of LEDs on muscle function, exercise capacity, and cardiorespiratory responses during isometric and dynamic exercise in patients with COPD. This study will assess 30 patients with moderate to severe obstruction (FEV1 ≤ 70% predicted). Isometric and dynamic protocols will be conducted in two visits each, for a total of four visits a week a part. First, a venous blood sample will be taken from the patients. The isometric protocol will start with the determination of the maximum voluntary isometric contraction (MIVC) to determine the workload (60% of MIVC) for the isometric endurance test (IET). Patients will be randomized to receive either the placebo or LED application. Immediately after finishing this procedure, the patients will carry out the IET until the limit of tolerance or until a 20% fall of strength is observed. After the test, another blood sample will be taken. In the other visit (one week later), the same order of procedures will be performed, except with the opposite (LED or placebo). For the dynamic protocol, the same procedures described above will be followed except with the maximal incremental cycle ergometer test used instead of the IET. The electromyography will be recorded during the isometric and dynamic protocols. Differences in muscle function, exercise capacity, and cardiorespiratory responses between the LED and placebo applications will be analyzed. The therapeutic effects of LED could minimize muscle fatigue in patients with COPD by increasing exercise tolerance.
The study is a clinical evaluation of an over the counter (OTC) combination product containing paracetamol (500 mg), dimethindene maleate (1 mg), phenylephrine hydrochloride (10 mg) compared to paracetamol (500 mg) alone in the treatment of nasal congestion, rhinorrhea, sneezing and other symptoms due to upper respiratory tract infection (URTI).
This multi-center, open-label study will evaluate the efficacy and safety of Pegasys (peginterferon alfa-2a) and Copegus (ribavirin) in relation to IL28-b gene expression in treatment-naïve patients with chronic hepatitis C genotype 1. Patients will receive Pegasys (180 mcg sc weekly) and Copegus ( 1'000 or 1'200 mg orally daily) for 48 weeks. Anticipated time of study treatment is 48 weeks, follow-up is 24 weeks.
The interest in studying the impact of aquatic exercise on muscle strength of patients with rheumatoid arthritis came after publication of several studies that pointed to the potential benefit of exercise on the natural history of the disease, including reduction of pain, better immune response as well as aerobic fitness and functional capacity and increase muscle strength, endurance and quality of life. In general, the aquatic exercises are indicated for patients with chronic joint diseases, since the aquatic environment seems to be more secure for this population due to the reduction of joint loading, as well as gain range of motion. However, there are some difficulties to show the real and consistent beneficial effect of physical activity in these patients, such as the small number of randomized controlled clinical trials, short intervention period (4-8 weeks), lack of details of the exercise protocols used, methodological problems (heterogeneous measures to evaluate the outcome, change of medication). Moreover, no study evaluated the disease activity, according to the tool most used clinically worldwide, the DAS28. It is known that aquatic exercises without impact in healthy subjects are sufficient to gain muscle strength. Nonetheless, in people with joint limitation the benefits from these same exercises to gain muscle strength is not known. To date, no studies addressing the effect of aquatic exercise on muscle strength and disease activity in patients with rheumatoid arthritis. In addition, there is the need to obtain a standardized protocol for prescribing of aquatic exercises. The choice of lower-limb strength was based on its relevance to the acceleration and deceleration during the march, as well as to perform activities of daily living, leisure and professional in these individuals. Thus, this study aims at: 1. Exercises performed in the aquatic environment and without the concomitant use of overhead equipment are sufficient to promote gain muscle strength in the lower limb? 2. What is the isolated effect of water resistance on muscle strength? Could it work as an impact that is used in exercises done on the land?
The purpose of this study is to evaluate the effectiveness of facet joint infiltration with corticosteroids in the treatment of low back pain due to facet joint osteoarthritis.
Parkinson´s disease (PD) diagnosis is based upon clinical examination. Although imaging has helped doctors to identify many diseases, it still does not add too much information for the diagnosis of Parkinson´s disease. The investigators are going to perform a large sample study including PD patients, essential tremor and healthy volunteers in order to evaluate if MRI can help in the diagnosis. Our hypothesis is that fractional anisotropy (FA) in the caudal portion of substantia nigra is decreased in PD patients.
