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 the study is to conduct a Bayesian randomized trial comparing non-elastic compression garments applied with high pressure (Circaid group) with no compression (control group) in reducing signs and symptoms in the acute stage of DVT and subsequent postthrombotic syndrome. With a hypothesis that the Circaid group will present a quicker and more marked reduction of pain and leg swelling in the acute stage of DVT, as well as a 20% decrease in the frequency of postthrombotic syndrome within six months from the time of diagnosis of the acute deep vein thrombosis episode.
Introduction: In Brazil, a person who is sixty years old or more is considered elderly. The incidence of osteoporosis and osteopenia has been increasing, as have fractures resulting from falls. Vitamin D deficiency can cause muscular atrophy in type II fibers (fast contraction and strength), which can increase the risk of falls. The aging process produces reduction in the ability of postural control system to maintain postural balance, which may increase postural instability and consequently increase the elderly risk to falls. Objective: To evaluate if vitamin D supplementation associated with regular exercise in vulnerable older women improves muscle strength and postural balance in 12 weeks. Methods: This will be a randomized prospective clinical trial, double blind, placebo-controlled intervention. Will be part of the study 40 elderly women vulnerable, who meet the inclusion criteria and that will be coming from the community through calls made by radio and social network. The volunteer will undergoing to blood test, body composition and bone mineral density, Mini Mental State Examination, Geriatric Depressive Scale, Falls Efficacy Scale, WHOQOL-OLD and WHOQOL-BREF instruments, functional capacity tests (MiniBEST, Time up and Go, Chair Rising Test, Six-minute walk test), muscular strength assessment (isokinetic dynamometry, handgrip and 1RM test) and postural balance (AccSway force platform for static postural balance and NeuroCom's Balance Master for dynamic postural balance) before and after 12 weeks of intervention with vitamin D supplementation and resistance and postural balance exercise. The intervention that will be perform during the 12 weeks with a progressive resistance training program.
Gingival fissures (GF) have been suggested as risk indicators for clinical attachment loss (CAL) and gingival recession, especially in free surfaces and in patients with low plaque scores. The major factors related to the GF occurrence are high daily brushing frequencies, excessive force to brush, malpositioned teeth, use of abrasive dentifrices, and stiffness of the toothbrushes bristles. Thus, in order to better understand the pathogenesis and progression of GF, this study aim to evaluate the incidence and behavior of GF in young adults using soft and medium brushes, in a cross-over randomized clinical trial along 6 months.
This is a study aimed at evaluating the efficacy of a topical anesthesia (test product) compared to placebo in adult patients of phototypes I to III, with indication of treatment of CO2 fractional laser in the forehead. In addition to efficacy, safety and tolerability of the product have been studied. The product under investigation is a topical formulation containing lidocaine 25 mg/g and prilocaine 25mg/g which in previous studies performed in the same institution with healthy subjects in adulthood showed faster onset than other formulations. In these previous studies, the product was well tolerated, and there were no signs of a skin reaction or adverse events of a systemic nature. The CO2 fractional laser treatment is routinely used by plastic surgery and dermatology for treatment with aesthetic purposes of skin imperfections. It's a procedure until certain painful point, which as a rule is performed without prior use of topical anesthetic. The test product is believed to produce a clinically significant reduction of pain when compared to placebo, during the application of CO2 laser on the forehead for the aesthetic treatment of the face.
This study will evaluate the role of systematic lymphadenectomy after sentinel node (SLN) mapping in high risk endometrial cancer (high grade histologies or deep myometrial invasion). The participants will be randomized in a non-inferiority controlled trial in 2 groups: SLN mapping or SLN mapping followed by systematic lymphadenectomy.
The purpose of this study was evaluate the comparative effects of FO rich in EPA (FO-EPA) and FO rich in DHA (FO-DHA) on inflammation and neutrophil properties after a prolonged and strenuous exercise. The effect of soybean lecithin on the same parameters and conditions also was evaluated.
This clinical trial evaluated the pharmacokinetics and pharmacodynamics of estriol in healthy post-menopausal women after the application of one vaginal ring containing one of three different dosages of estriol (100 mg (Test 1), 300 mg (Test 2) or 600 mg (Test 3)) with continuous delivery (0.125, 0.250 or 0.500 mg/day) for 21 days. And also, characterized its safety and tolerability.
This study is designed to evaluate the safety, tolerability and efficacy of long-term treatment with PF-06741086 in subjects with severe hemophilia who participated in the 3-month Phase 1b/2 B7841002 study. Additionally, de novo subjects will be recruited into this study.
The objective of this study is to evaluate the macular and choroidal thickness of patients submitted to intracameral moxifloxacin during the phacoemulsification surgery for endophthalmitis prophylaxis. The investigators propose a randomized clinical trial double-blind. The patients will be divided into two groups: one will receive intracameral moxifloxacin injection during phacoemulsification surgery and the other won't. Both Spectral Domain - Optical Coherence Tomography (SD-OCT) and Enhanced Depth Imaging - Optical Coherence Tomography (EDI-OCT) will be performed for each patient pre-operatively and on the 30th and 60th postoperative days. After collecting, the data will be compared to evaluate if there was any difference in the macular thickness and choroidal thickness between the two groups.
The purpose of this program is to provide early access to ustekinumab where it is commercially unavailable for the treatment of participants with moderately to severely active Crohn's disease who have failed treatment with conventional Crohn's disease therapy (example, immunomodulators or corticosteroids) and Tumor Necrosis Factor alpha (TNF alpha) antagonist therapy (e.g., infliximab, adalimumab, certolizumab pegol, or their biosimilars), or who are intolerant to, or have a contraindication to these treatments. During the course of this early access program (EAP), through the reporting of serious adverse events (SAEs) and non-serious adverse drug reactions (ADRs) by participating physicians, information on the safety and tolerability of ustekinumab will be captured.
