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.
Osteoarthritis (OA) is one of the main causes of chronic pain and physical disability, which directly impacts the quality of life of patients. The prevalence of OA among adults over 60 years of age is approximately 13% in women and 10% in men. Knee OA (gonarthrosis) has as main risk factors, in addition to age, female gender and obesity. Pharmacological treatment of gonarthrosis is based on approaches to reduce symptoms and/or pain, with joint replacement (arthroplasty) being reserved for more advanced forms of the disease. In general, currently available treatments have only moderate effects and low satisfaction rates among patients. Photobiomodulation Therapy (TFBM) has been used for at least 50 years by health professionals to treat a variety of clinical conditions, especially those associated with chronic pain. TFBM is a treatment using a non-ionizing light source such as Low Intensity Laser (LBI) or Light Emitting Diodes (LED), with near-infrared wavelengths. The aim of this study is to evaluate the intensity of knee pain in the short and medium term after photobiomodulation therapy in patients with gonarthrosis. In this multicenter, randomized, placebo-controlled, double-blind clinical trial, 238 volunteers with gonarthrosis grades II and III according to the Kellgren-Lawrence classification will be recruited to be administered adjuvant treatment with TFBM. The TFBM will be performed in the knee region, twice a week, for five weeks, totaling 10 sessions. Volunteers will be allocated in the intervention group (n=119) or in the placebo group, which will be treated with 10 sessions of inert light (n=119). The hypothesis is that the photobiomodulation therapy will have a positive impact, in the short and medium term, on improving pain, functionality and quality of life of patients with symptomatic gonarthrosis.
This study will investigate the clinical performance of a novel restorative glass ionomer (DeltaFil, DMG) in comparison to an established restorative glass ionomer (Riva Self Cure HV, SDI) in the restoration of Class II cavities in primary molars.
This phase 2 study aim to investigate the effect of dobutamine in patients with sepsis/ septic shock after fluid resuscitation and with hypoperfusion (lactate and central venous oxygen saturation or prolonged capillary refill time) on renal function as compared with usual care.
Forty-four patients with dentin sensibility after non-surgical scaling and root planning (SRP) will be randomly included in 2 groups: Experimental Group: SRP+ Photobiomodulation (PBM) (660nm, 100W, area 0,5cm2, 200w/cm2, 30 seconds, 3 J, 6J/cm2. The primary outcome of the study will be the assessment of dentinal sensitivity after 7 days of RAR measured with the visual analog scale (VAS). The cutoff of VAS is 3. Also, it will be assessed the impact of oral health on the participant's quality of life, with the OHIP-14 questionnaire. The use of analgesics (paracetamol) will be prescribed as needed and the amount of medication will be calculated. These outcomes will be evaluated after 7 days and 1 month of application
This prospective, international, multicenter observational study will include hospitals performing pediatric surgery in participating Latin American countries. We aim to assess the incidence of hospital postoperative complications in pediatric surgical patients < 18-years-old in Latin America. We will recruit all consecutive pediatric patients under the age of 18 years who were admitted to participating hospitals undergoing elective and nonelective surgery. The primary outcome is in-hospital postoperative complications up to 30 days after surgery.
The study will aim to find out if the drug andexanet alfa is safe and effective in preventing major bleeding during urgent surgery or invasive procedures. The study will compare the use of andexanet alfa to the usual care given at the study center.
ntroduction: Parkinson's disease (PD) is characterized as a neurodegenerative disorder associated with progressive loss of dopamine in the basal ganglia region, resulting in classic motor symptoms such as bradykinesia, rigidity, postural instability and tremor. Such symptoms end up affecting the functionality of the upper limbs (MMS) in this population. In recent years, Virtual Reality (VR)-based therapy has been gaining popularity, but studies in the area are still lacking. Objective: To verify the benefits of virtual reality in individuals with PD above 65 years of age and in individuals below 65 years of age in the functionality of the upper limbs and to identify possible differences between them. Methodology: This is a randomized clinical trial, in which the evaluators will be separated into two experimental groups (single-blind). Subjects with PD will be randomized into two groups: Group Over 65 years of age (GI1), and Group below 64 years of age (GI2). Both will receive treatment with virtual reality games in a non-immersive environment (flat screen) through the Leap Motion Controller (LMC) device. Both treatments will focus on large and fine upper limb tasks, in a protocol with 4 activities and duration of approximately 27 minutes, twice a week, for eight weeks. The two groups will be evaluated in three moments: before the intervention and immediately after 8 weeks. They will be analyzed at the ADL level, through the TEMPA test and part II of the unified PD assessment (MDS-UPDRS II); motor assessment (part III) of the MDS-UPDRS and motor staging of PD (Hoehn & Yahr); manual dexterity through the Box and Block test and the Nine Hole Peg Test; cognition by Montreal Cognitive Assessment (MoCA); quality of life through the PD questionnaire (PDQ-39); the usability of the system (SUS); and possible side effects (Simulator Sickness Questionnaire). It is expected that this study will show that the treatment applied to the younger population presents better results when applied to the older population.
Nonalcoholic steatohepatitis (NASH) is the most common cause of chronic liver disease in Western countries and one of the leading causes of liver transplantation in the world. Its spectrum ranges from simple steatosis to decompensated cirrhosis, resulting from progressive fibrosis due to inflammation and cellular injury. The reasons why patients with the same degree of steatosis have different evolutions are not sufficiently known. The objective of this project is to identify biomarkers that predict disease progression, using omics techniques, which can serve to develop new therapeutic strategies.
Feasibility study of a new medical device that will evaluate the usability and effectiveness of a cycle ergometer device associated with neuromuscular electrical stimulation (FES cycling). The study's objective is to evaluate the effect of the application of functional electrical stimulation of the new device on participants' quadriceps muscle strength in comparison to a medical device with similar characteristics and to a control group. Secondarily, the study will compare the usability of the two medical devices as evaluated by the participants and the therapists who apply the treatment, as well as the participants' satisfaction with the treatment, identifying possible adverse effects.
This study was designed with the objective of evaluating the protection potential provided by the experimental product (Liquid Bandage) by evaluating its barrier formation capacity. Once the product's ability to form a barrier is confirmed, its ability to protect against small skin injuries, such as small cuts and bruises, blisters and cracks, is confirmed. The barrier formation also guarantees protection against the formation of calluses.
