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.
This trial is conducted globally. The aim of the trial is to evaluate cardiovascular and other long-term outcomes with semaglutide in subjects with type 2 diabetes. The trial is event-driven, i.e. the maximum trial duration (up to max. 148 weeks) will depend on the accrual of major adverse cardiovascular events (MACE) in this trial and the remaining research programme. The incidence of MACE will be monitored throughout the trial which will be terminated according to plan when pre-specified stopping criteria are met.
Among the adjuvants to local anaesthetics (LA), the enzyme hyaluronidase is most often used as a diffuser agent of the LA in ophthalmic anaesthesia. It serves to improve clinical efficacy and prolong anaesthesia as an alternative to long-lasting and potentially more dangerous LA, especially in patients with increased cardiovascular risk. There is scarce clinical data about the safety of the use of hyaluronidase in dental procedures. This study aimed to compare hemodynamic and electrocardiographic variables during a dental surgical procedure using a local anaesthetic associated with hyaluronidase or placebo in healthy subjects.
Background: depression during pregnancy is an important problem for public health. It has direct consequences for the affected woman, her children and family, and is a strong predictor of post-partum depression. In developing countries depression during pregnancy is highly common, and usually unrecognized and untreated. Aim: to evaluate the effectiveness and cost-effectiveness of an intervention delivered by nurse assistants in the management of pregnant women with depression in primary care clinics that adopt the Family Health Strategy in Sao Paulo, Brazil. Method: PROGRAVIDA is a cluster randomized controlled trial with pregnant women with depression attending pre-natal care in 12 Primary Care Units with Family Health Program, covering an area of 400,000 inhabitants in Sao Paulo, Brazil. The intervention follows a stepped-care approach and is delivered by health professionals working at the primary care unit responsible by the care of the women. All women from the intervention group receive a program based on psycho-education and problem solving techniques, delivered by a nurse assistant at the women's homes. The program comprises 8 sessions, 6 during pregnancy and 2 after delivery. Intensity of depressive symptoms is assessed using the PHQ-9, at the beginning of the sessions. Women with severe depression are referred to the family doctor and are assessed for the need of antidepressant medication. The control group receives routine care. The primary outcome is remission of depressive symptoms 4-months after the inclusion in the study. Secondary outcomes include remission of depressive symptoms at 6 months after delivery. Women are also assessed for socioeconomic and household characteristics, social support and obstetric complications. The effectiveness and cost-effectiveness of the intervention will be assessed with intention-to-treat analysis, using the clinical outcome and the assessment of quality of life (EQ-5D) four months after inclusion in the trial.
The purpose of this study is to compare the efficacy of graded activity program and supervised exercise on pain, functional disability, quality of life, global perceived effect, return to work, physical activity, physical capacity and strength of the lower limbs in patients with chronic non-specific low back pain
This study will investigate the efficacy and safety of two doses (high and low) of empagliflozin in combination with metformin (500 mg and 1000 mg) administered twice daily in patients with type 2 diabetes mellitus (T2DM). Study will compare four dose combinations of empagliflozin + metformin versus each individual component after 24 weeks of treatment.
Although arginine vasopressin has been used as an additional drug in refractory shock in worldwide clinical practice, there are no prospective studies using it as a first choice therapy in patients with cancer and septic shock. The aim of this study is assess if the use of arginine vasopressin would be more effective on treatment of septic shock in cancer patients than norepinephrine, decreasing the composite end point of mortality and organ failure in 28 days.
The care of the oral cavity is an important way to prevent local and systemic infections. This study aimed to: evaluate the use of video as a teaching strategy of oral hygiene for patients undergoing chemotherapy. The methodological design used was quasi-experimental before-after intervention. The sample consisted of 23 subjects who performed the technique of oral hygiene before and after watching an educational video. To do so was given a kit with a toothbrush with soft bristles, toothpaste with low abrasivity, mouthwash or product to mouthwash and dental floss for oral hygiene. For data analysis we applied the parametric test t "Student" paired.
Rationale: Recently our study group reported the results of the Basilar Artery International Cooperation Study (BASICS), a prospective registry of patients with an acute symptomatic basilar artery occlusion (BAO). Our observations in the BASICS registry underscore that we continue to lack a proven treatment modality for patients with an acute BAO and that current clinical practice varies widely. Furthermore, the often-held assumption that intra-arterial thrombolysis (IAT) is superior to intravenous thrombolysis (IVT) in patients with an acute symptomatic BAO is challenged by our data. The BASICS registry was observational and has all the limitations of a non-randomised study. Interpretation of results is hampered by the lack of a standard treatment protocol for all patients who entered the study. Objective: Evaluate the efficacy and safety of IAT in addition to best medical management (BMM) in patients with basilar artery occlusion. Study design: Randomised, multi-centre, open label, controlled phase III, treatment trial. Study population: Patients, aged 18 years and older, with CTA or MRA confirmed basilar occlusion. Intervention: Patients will be randomised between BMM with additional IAT versus BMM alone. IAT has to be initiated within 6 hours from estimated time of BAO. If treated with as part of BMM, IVT should be started within 4.5 hours of estimated time of BAO. Main study parameters/endpoints: Favorable outcome at day 90 defined as a modified Rankin Score (mRS - functional scale) of 0-3.
This is a large prospective registry of patients submitted to cardiac electronic devices implantation designed to investigate the incidence, risk factors and prognostic of thromboembolic complications associated with transvenous lead implantation.
Previous experimental and clinical studies have consistently suggested that right ventricular (RV) apical pacing has important adverse effects. Ventricular pacing, however, is required, and cannot be reduced in many patients with atrioventricular block. The SAFE-LVPACE study is a randomized controlled trial that compare the effects of conventional right ventricular (RV) pacing vs. left ventricular (LV) in patients with AV block.
