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.
Reducing the rest time after diagnostic cardiac catheterization for three hours does not increase the complications concerning to the procedure, compared to the rest of five hours.
Epidemiological study about eye discomfort complaints, comorbidities and diagnosis at a Brazil`s ophthalmological public care service
The present study intends to assess the efficacy of 3 drops of 5% povidone-iodine (PVPI) eyedrops in reducing the bacterial flora in a conjunctival sac fundus compared to the standard procedure consisting of the application of 1 PVPI eyedrop 2 min before any intraocular surgical procedure.
This open-label, multicenter, non-randomized study provided continued access to vemurafenib for eligible participants with BRAF V600 mutation-positive malignancy, who were previously enrolled and treated in an antecedent vemurafenib protocol and did not meet the protocol's criteria for disease progression, or were treated beyond progression and were still deriving clinical benefit (as assessed by investigator), and may have therefore potentially benefited from continued treatment with vemurafenib. Participants received treatment with oral vemurafenib at 960 milligrams (mg) twice daily (BID), 720 mg BID, or 480 mg BID, depending on the last dose in the antecedent protocol. Treatment continued until progression of disease or as long as the participant was deriving clinical benefit, as judged by the investigator (case-by-case decision with approval of the Medical Monitor), death, withdrawal of consent, unacceptable toxicity, loss to follow-up, or decision of the Sponsor to terminate the study, whichever occurred first.
This is a clinical study to evaluate the efficacy of a lateral wedge insole with subtalar strapping in knee osteoarthritis treatment.
Osteoarthritis (OA) is a highly prevalent and disabling disease. It is estimated that by 2030 the prevalence of symptomatic OA could reach 30% of the population above 60 years. It is associated with significant morbidity being one of the most common causes of joint pain, functional disability and compromised quality of life. This randomised controlled trial will investigate the effect of low-level laser therapy (LLLT) and static stretching exercises, as monotherapy and in combination, on pain, quality of life, function, mobility, knee range of motion (KROM) and hamstring length in participants with knee OA. This study will involve 145 people aged 50-75 years with symptomatic radiographic knee OA and will consist of two types of treatments: Low-level laser therapy (LLLT) and stretching exercises. The patients will be randomly allocated to five study groups LLLT active+Stretch, LLLT placebo+Stretch, Stretch, LLLT and Control (with n=29 each). Treatment frequency will be three sessions/week for all active groups. LLLT will involve the use of a Galium-Arsenide laser (904nm, 40 milliwatts, 3 Joules/point, 27 Joules/knee) over 24 sessions for the monotherapy group and 9 sessions for the LLLT+Stretch groups. Stretching will consist of seven exercises completed over 24 sessions. The control group will receive a booklet. The primary outcome is pain measured by Visual Analogue Scale. Secondary outcomes included quality of life assessed by Western Ontario and McMaster Universities Arthritis Index (WOMAC), function by Lequesne Algofunctional Index, mobility by Timed Up and Go Test (TUG), KROM by goniometry of knee flexion and hamstring shortening by popliteal angle. The statistical method will follow the principles of per-protocol analysis.
Adults with Attention Deficit Hyperactivity Disorder (ADHD) have impairments in attentional subsystems of alerting and conflict monitoring. Mindfulness meditation may lead to an improvement of these deficits, and reduces symptoms of anxiety and depression. However, the studies that demonstrated these improvements did not use a control group, nor controlled the use of medication. In the present study the investigators will examine the effects of the mindfulness practices (same protocol of 8 weekly sessions used in the study that showed positive effects in this disorder) in the performance of adult patients and healthy people (with ADHD). Cognitive performance, mood, and the quality of life will be assessed by validated questionnaires before and after treatment/standby.
Parkinson's disease is a common neurodegenerative disorder in which patients experience progressive motor disability and many disabling non-motor symptoms. Recent studies have consistently found that people who do not use caffeine are at higher risk of developing Parkinson's disease. This suggests that caffeine may have potential as a treatment for PD. In a pilot study of caffeine for daytime sleepiness in PD, there was evident benefit on the motor manifestations of disease. There have been other lines of evidence that have suggested caffeine could be useful in PD. This study is to evaluate the efficacy of caffeine 200 mg BID vs matching placebo for motor and non-motor aspects of disease. This will be in three stages. In the first six-month stage, medications will be held constant, to see whether caffeine does have motor benefits. Then we will perform a four-year extension stage to define if the effects of caffeine persist (or even magnify), and to see if caffeine helps reduce dose of other PD meds and/or prevents their side effects. Finally, we will finish with a six-month stage in which we will place all patients on caffeine - this will allow us to assess caffeine's use in later disease, but more importantly, will assess whether early use of caffeine produces long term changes beyond its immediate effects.
The purpose of this study is to evaluate whether MST-188 can reduce the duration of vaso-occlusive crisis (VOC) in subjects with sickle cell disease. The study will also evaluate whether MST-188 can reduce the frequency of rehospitalization of subjects due to a recurrence of VOC. Additionally, this study will compare the development of acute chest syndrome during VOC in subjects who receive MST-188 to those who do not receive MST-188.
The purpose of this study is to evaluate the efficacy and safety of inotersen given for 65 weeks in participants with Familial Amyloid Polyneuropathy (FAP).
