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 objective of this study is to evaluate the effects of LED phototherapy associated with a resistance training protocol on the peripheral muscle function of moderate to severe asthmatic patients ..
Hypertension is the most prevalent cardiovascular disease risk factor among individuals 60 years of age and older. Hypertension can be prevented and modified with lifestyle interventions that include regular exercise. Water exercise is widely recommended for older adults for a variety of health benefits, but few studies have assessed the immediate ambulatory blood pressure (BP) response to water exercise, a response termed postexercise hypotension (PEH). We will assess PEH after a session of water aerobics in physically active, older women with hypertension. Twenty-four women will be randomly assign to participate in a 45 min session of moderate intensity, water aerobics (WATER) and a 45 min land control session (CONTROL). All experimental sessions will start at 9 am sharply with 7 days between them. Subjects will left the experiments wearing an ambulatory BP monitor for the next 21 hr.
50 patients with pancreatic mass will undergo endoscopic ultrasound-guided fine needle aspiration using two techniques: negative pressure and slow-pull. Cytological results will be compared.
The primary aim of our study is to evaluate the effect of intracervical anesthesia on pain scores immediately following levonorgestrel-releasing intrauterine system (LNG-IUS) insertion in nulligravida women.
This was a multicenter, randomized study to evaluate the safety, immunogenicity, and efficacy of VRC-ZKADNA090-00-VP (Zika virus wildtype DNA vaccine) or placebo. In Part A, the primary objective was to evaluate the safety and tolerability of the vaccine in different vaccination regimens. In Part B, the primary objectives were to evaluate the safety and efficacy of the vaccine compared to placebo.
The study will be conducted as a randomized, controlled, double blind Phase 1b dose-escalating clinical trial in up to 60 healthy adult males and non-pregnant females living in the S. mansoni-endemic area of Americaninhas, Brazil. The primary objective of this trial is to assess the safety and reactogenicity of ascending doses of Sm-TSP-2/Alhydrogel(R) (10mcg, 30mcg, or 100mcg) vaccine with or without AP 10-701 given as three doses administered on Days 1, 57, and 113.
This study aim to evaluate the effects of 16 weeks of multicomponent training on postural control, cardiovascular and musculoskeletal systems in pre-frail elderly through nonlinear and linear measurements.
The Zika infection is a viral disease that is transmitted to humans by the same mosquito that transmits Dengue and Chikungunya fever. The Zika virus has been found in various body fluids such as urine, blood and semen, but we do not know how long it persists in these fluids. For example, parts of the virus were reported to persist in semen after six months of the onset of symptoms, but we do not know if the virus can stay longer. In this way, we want to investigate how long the Zika virus can be found in other secretions besides blood and urine. Study Hypothesis: ZIKV can be shed in human body fluids long after the time of the acute infection. Persistence of ZIKV in different body fluids may vary due to the influence of circulating specific ZIKV IgM and IgG, as well as host and environmental factors.
The objective of this randomized controlled clinical study was to evaluate the increase in the volume of peri-implant gingival tissue in implants installed in the aesthetic areas with the use of subepithelial-conjunctive tissue graft, and a sample of 40 individuals with implants Aesthetics where the test group (n = 20) will receive tec graft. (N = 20) will receive only the dental implant without the placement of a tec graft. Epithelial-conjunctival.
Despite the high success rates of gastric bypass in the short and long terms, little is known about possible anatomopathological changes that can occur in these patients. The objective is to investigate preoperative and postoperative endoscopic changes in patients undergoing gastric bypass without a ring. Thirty obese patients from different regions of the country with the surgical indication for the Roux-en-Y gastric bypass will be studied prospectively. All patients will be submitted to upper gastric endoscopy (UGE) two, six and 12 months after the surgical procedure at the Kaiser Clinic. This study will identify whether there are endoscopic changes within one year after the surgery and what they are. Changes, if they exist, will be correlated with clinical data, in order to make an accurate prognosis of the patient, thereby contributing to the outcomes of future patients submitted to this type of procedure.
