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.
PATH is a member of a consortium that is developing a Diagnostic Enterics Card (DEC) which will allow clinicians to diagnose a group of diarrheagenic pathogens linked to morbidity and mortality. The pathogens detected on DEC include Salmonella, Campylobacter jejuni, Shigella species, and Escherichia coli O157:H7. This study will evaluate the performance of the assays and the platform in clinical conditions with non-expert users. It will provide important data on the performance of DEC for at least one target pathogen, an understanding of the potential impact of different sample types on device performance, and human factors associated with instrument interface in the field.
The aim of the study is to determine the effect of cerclage pessary on the incidence of spontaneous delivery between randomization (at 20-24+6 weeks) and 33+6 weeks in asymptomatic women with singleton pregnancies found at routine mid-trimester screening to have a cervix of <25 mm in length and in twin pregnancies.
The primary purpose of the study is to help answer whether tadalafil taken once a day can help improve the psychological outcomes (such as sexual self confidence, spontaneity and time concerns) compared to sildenafil taken as needed in patients with erectile dysfunction (ED).
In studies of Exubera in persons with diabetes, lung cancer occurred in a few more people who were taking Exubera than in people who were taking other diabetes medicines. All subjects diagnosed with lung cancer had a history of smoking and the number of lung cancer cases observed fell within the expected range based on population-based data. There is currently not enough information to determine if any of the observed lung cancer cases were related to Exubera use, therefore, the study is being conducted to further investigate whether Exubera use makes the appearance of lung cancer more likely.
The aim of this study was to compare two management options for CIN 2. This randomized clinical trial performed between 2003 and 2006. A series of 90 Brazilian women diagnosed as CIN2 were randomized into two groups: 1) 45 whose lesion was excised and,2) 45 women subjected to follow-up at 3-month intervals for 12 months.
Safety and efficacy of antibiotic steroid combination compared with individual administration in the treatment of bacterial ocular inflammation and infection (blepharitis and/or keratitis and/or conjunctivitis).
To understand the dose-response characteristics of PF-00885706 for efficacy in terms of symptomatic relief when used as add-on treatment to esomeprazole 20mg (standard proton pump inhibitor [PPI] treatment), in subjects with gastro-esophageal reflux (GERD) who have inadequate relief with PPIs.
To prove the safety, in normal conditions, of the Cepacol Teen, a formulation to odontological usage.
Although effective therapy for tuberculosis is available, TB continues to cause significant problems worldwide, and rates of multi-drug resistant (MDR) TB cases are on the rise. A major obstacle to the control of TB is poor adherence with lengthy (usually 6 months) and complicated treatment regimens. Incomplete TB treatment can lead to serious consequences such as increased severity of illness and death, prolonged infectiousness and transmission in the community, and the development of drug resistance. The development of new treatment strategies with more stronger drugs could lead to shorter and simpler regimens. A TB treatment regimen that allowed treatment duration to be meaningfully decreased would have important public health implications. This trial will compare the effect and safety of a new oral regimen to that of the standard regimen for the first phase of treatment for pulmonary tuberculosis. The experimental regimen will consist of the following: - Two months of isoniazid, rifapentine, pyrazinamide and moxifloxacin (HPZM) administered once daily. Pyridoxine (vitamin B6) will be given with each dose of isoniazid. The standard control intensive phase regimen will consist of the following: - Two months of isoniazid, rifampin, pyrazinamide, and ethambutol (HRZE) administered once daily. Pyridoxine (vitamin B6) will be given with each dose of isoniazid. Following intensive phase therapy (the study phase), all patients will be treated with a non-experimental continuation phase regimen. In mice, the combination of Moxifloxacin and Rifapentine have cured the animals significantly faster than the standard regimen and this study will be the first step to see if the potential is also there in humans.
This was a double-blind community-based trial, placebo controlled. During 16 weeks, children in the intervention group (GI, n=180) received iron fortified rice, and children in the control group (GC, n=174) received rice with placebo. Anemia was considered present when hemoglobin < 11.0g/dL. Comparison of mean variation on hemoglobin between groups was accessed by using Student's t-test. Hemoglobin concentration improved in both groups, with mean increase of 0.42 g/dL in GI (11.28±1.23 g/dL to 11.75±1.16 g/dL, p < 0.001), and 0.49 g/dL in GC (11.06±1.13 g/dL to 11.51±1.16 g/dL, p < 0.001). Anemia decreased (p < 0.01) in both groups (37.8% to 23.3% in GI and 45.4% to 33.3% in GC), with no differences between them. Hemoglobin increase was significantly higher in children who received total amount of iron ≥ 53.76 mg from fortified rice, compared to those who received less than this cut-off value (0.94 g/dl vs 0.39 g/dl p=0.03). The results suggest that this type of intervention can be useful in anemia control if fortified food intake is adequate.
