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 purpose of this study is to assess the effects osteopathic techniques at the upper cervical vertebrae or at the sphenopalatine ganglia on the intraocular pressure.
The control of blood pressure (BP) in the elderly is influenced by several factors, among them, the measurement methodology. The measurement of BP in the office is prone to failures, so the use of technology associated with blood pressure measurements at home is an alternative to minimize failures and contribute to the optimization of treatment. The objective of this study will be to evaluate the adequacy of the treatment of Systemic Arterial Hypertension (SAH) in primary care using Home Blood Pressure Monitoring (MRPA). Method: Randomized clinical trial with hypertensive patients, aged 60 years or over, attended at the Family Pharmacy service inserted in the primary care of the municipal health network. The subjects who accept to participate in the study will be randomized to the intervention / control groups. submitted to MRPA, will undergo analysis of the pharmacotherapy prescribed for the treatment of SAH, collection of clinical data, which together will support the assessment of the adequacy of the treatment of hypertension. When inadequacies in pharmacotherapy are identified, suggestions for changes will be forwarded to the prescriber / professional or assistant health team, weighted by the pharmacist in agreement with the patient and according to the guidelines of the Brazilian Guideline on Hypertension. The outcomes: changes in treatment and blood pressure control in the intervention and control groups will be evaluated.
This multicountry, multicenter, retrospective, non-interventional study involving patients diagnosed with HER2-positive unresectable or metastatic breast cancer mBC will be conducted to understand the demographic and clinico-pathological profile of the patients, diagnostic practices for human epidermal growth factor receptor 2 (HER2) status, current treatment landscape and sequencing of therapies, associated burden of toxicities with all lines of treatment (LOTs), and survival outcomes in the real-world setting.
The effect of handgrip training on blood pressure reduction has been demonstrated in several studies. However, acutely, there is still divergence regarding the effects of isometric handgrip exercise on blood pressure responses, especially when it is performed at different times of the day. It is suggested that the magnitude of blood pressure reduction after a single exercise session is able to predict long-term blood pressure behavior. Thus, understanding the effects of isometric handgrip exercise, performed at different times of the day, on blood pressure in adult hypertensive individuals acutely may help to understand the effects of this type of exercise chronically.
This trial is evaluating if rivaroxaban 2.5 mg BID and aspirin 100 mg OD compared to aspirin alone improves on intermittent claudication distance in PAD patients.
Randomized clinical trial to compare the patient's experience after peripheral venipuncture catheterization using the conventional technique (vein visualization and palpation) versus ultrasound-guided venous puncture. Patients with indication of peripheral venous puncture, admitted to the clinical inpatient units on the hospital where the study will be conducted (Hospital de Clinicas de Porto Alegre - HCPA) will be enrolled in this single-center trial and will be randomized to conventional peripheral venipuncture performed by a registered nurse; or ultrasound-guided peripheral venipuncture performed by a registered nurse with expertise in vascular access.
Randomized clinical trial to test the assertiveness on the peripheral vein puncture attempt by comparing two methods: peripheral venipuncture catheterization using the conventional technique (vein visualization and palpation) versus ultrasound-guided venous puncture. Patients with indication of peripheral venous puncture, admitted to the clinical inpatient units on the hospital where the study will be conducted (Hospital de Clinicas de Porto Alegre - HCPA) will be enrolled in this single-center trial and will be randomized to conventional peripheral venipuncture performed by a registered nurse; or ultrasound-guided peripheral venipuncture performed by a registered nurse with expertise in vascular access.
This is a retrospective, multinational, non-interventional, observational study. A series of cohort studies will be conducted to assess the prevalence of undiagnosed stage 3 CKD in each region. The study will also assess the current state of CKD management in patients with undiagnosed CKD
The purpose of the study was to compare the clinical effectiveness of bonded versus vacuum-formed retainers regarding their retention capacity; periodontal health; survival rates; and patients' perception after 12 months of removal of fixed appliances. The null hypotheses considered that there was no differences between the retainers in relation to the aspects evaluated.
The purpose of this study is to confirm the reproducibility that the MEDL score can be evaluated by Magnetic Resonance Imaging (MRI) in the similar way as laparoscopy, the gold standard for the evaluation of the disease state of endometriosis, in order to establish the MEDL score, a new evaluation index for endometriosis using MRI. Approximately 70-90 patients with endometriosis diagnosed by imaging and who are candidates for fertility-preserving surgery will be recruited retrospectively or prospectively, and the disease status of endometriosis will be evaluated using preoperative MR images, laparoscopic surgery videos, etc. The relationship between the condition and clinical symptoms, such as pain, is also considered.
