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.
Chronic sun exposure enhances the incidence of cutaneous neoplasms (NMSC - non melanoma skin cancer), wrinkles, roughness, telangiectasia and irregular pigmentation of the skin. Nowadays, actinic keratosis (AK) are considered in situ squamous cell carcinoma (SCC), and should be managed that way. Conventional topical Photodynamic therapy (PDT) has proven its efficacy on treatment of AK and cancerization field. PDT's action in global improvement of photodamaged skin, texture, pigmentation and reduction of wrinkles has been well documented in literature. Immunohistochemical and histopathological essays describe the hypothesis of conventional PDT's mechanisms of action in photoaging by dermal remodeling, with enhancement of collagen, statiscally significant. Daylight-Photodynamic Therapy (DL-PDT) is a new modality that keeps the efficacy of topical PDT in treatment of AK and cancerization field, but painless and more practically. Until this moment, there is no report of DL-PDT efficacy on photorejuvenation and actinic keratosis evaluated by clinical, histopathological and immunohistochemical studies. The investigator's aim is to evaluate the alterations induced by isolated DLPDT or DLPDT associated with other techniques of transepidermal drug delivery (microneedles, CO2 laser and microdermabrasion) in the treatment of field cancerization in photodamaged skin with actinic keratosis, through clinical evaluation, histopathological and immunohistochemical studies. It is an interventional, prospective, randomized controlled, parallels-groups, four-arm trial with 1:1 allocation ratio study performed in forty patients attended at the Dermatology Service of Hospital Universitário Antonio Pedro- Universidade Federal Fluminense.
Introduction: Atraumatic and degenerative rotator cuff tears are common in individuals over 55 years of age. This condition can have a high impact on social life and is associated with chronic pain, weakness and dysfunction of the upper limb. There is evidence that conservative approaches should be the first treatment option. Conservative treatment usually addresses a variety of therapeutic behaviors without providing scientific arguments for the choice and progression of exercises. At that, there is a gap in the literature on the best exercises for this population, whether they are exercises to strengthen the remaining fibers of the rotator cuff or exercises focused on strengthening other shoulder muscles with rotator cuff unload exercise program. Objective: To compare the effects of two different exercise programs based on the load of the rotator cuff on a population with shoulder pain and rotator cuff tear. Methods: This is a controlled, randomized, blinded clinical trial. In this study 78 individuals with shoulder pain and presence of atraumatic rupture of the rotator cuff muscle tendon will participate and will be randomly distributed between two groups. The primary outcome will be quality of life (WORC index), and secondary outcomes will include pain, function (DASH), fear avoidance beliefs (FABQ-Brazil), kinesiophobia (Tampa Scale), pain catastrophizing scale, muscle strength of abductors, lateral and medial rotators of the shoulder, range of motion of arm elevation and patient satisfaction. All outcomes will be measured before and after 12 weeks of treatment (2x/week), and 1 month after the end of treatment. The normality of the data will be verified by the Kolmogorov Smirnov test. The differences between the groups will be verified using the mixed linear models with the terms of interaction versus time. The effect size will be calculated for the variables between the groups. The level of significance will be 5%.
Halitosis is the term used to define an unpleasant odor emanating from the mouth. Some lung diseases and diabetes are among the extra-oral causes of this condition. However, no studies have evaluated the causes and treatment of halitosis in the population of older adults with denture. A randomized, controlled trial is proposed. The patients will be divided into 2 groups: G1: older adults who wear complete dentures and will be treater with tongue scraper (n = 20); G2 older adults who wear complete dentures and will be treater with PDT (n = 20). If the halitosis persists, the participants will be submitted to hygiene procedures for the mucosa and dentures. The evaluation of halitosis will be repeated. If the halitosis is resolved, the participants will return after one week for an additional evaluation. This protocol will determine the effectiveness of photodynamic therapy regarding the reduction of halitosis in older adults with complete denture.
The study seeks to assess the effectiveness of Sanofi Pasteur´s dengue vaccine (Dengvaxia®) according to the age, dose and municipality of residence in five municipalities of Paraná State. Specific objectives include: - To assess the effectiveness of Dengvaxia® in preventing dengue hospitalization and dengue symptomatic cases. - To assess the effectiveness of Dengvaxia® in preventing dengue hospitalization and dengue symptomatic cases according in the following age groups 15 to 18 and 19 to 27 years of age in the municipalities of Maringá, Foz de Iguaçu, Londrina, Sarandi and Paranaguá. - To assess the effectiveness of Dengvaxia® in preventing dengue hospitalization and dengue symptomatic cases in the following age groups 9 to 14 and 28 to 45 years of age in the municipality of Paranaguá.
LUCAX01 is a cohort study with patients with advanced NSCLC in tobacco users. in this study, patients will be submitted to baseline physical tests, blood and biopsy sample collection, and the main objective is to study the functional and prognostic implications of cachexia and to validate skeletal muscle dysfunction markers.
There are physiotherapy techniques, known as lumbar mobilization, proprioceptive neuromuscular facilitation, massage therapy, windsheets and foam roller that present good results in stretching the legs. This study aims to evaluate which of these techniques has a better result in leg stretching. It is believed that massage therapy and lumbar mobilization will provide better results.
The aim of this prospective observational study will be to evaluate patient-related outcomes, clinical, microbiological and peri-implant immunoinflammatory mediators in completely edentulous patients rehabilitated with delayed loaded overdentures prostheses. The investigators hypothetize that this system could restore edentulous patients with healthier mucosal concerning clinical, microbiological and immunoinflammatory parameters, besides to promote improvement in patient satisfaction and quality of life.
Upper limb paresis is the most common type of post-stroke neurological impairment and a major cause of functional disability. Repetitive peripheral electrical stimulation (RPES) is a novel strategy to improve upper limb motor performance in the post-stroke chronic phase but its effects in the subacute phase are still poorly understood. The objectives of this study are to compare the effects of RPES on motor performance of the upper limb in the subacute and chronic phases of stroke, and to identify the mechanisms underlying this intervention.
The purpose of this non-interventional study is to identify participants with urothelial cancer (UC) and selected fibroblast growth factor receptor (FGFR) aberrations through molecular testing of their archival tumor tissue.
The purpose of this study is to characterize the multiple myeloma (MM) population concerning demographics and clinical characteristics (for example. frailty, risk strata, manifestations of target organ damage [TOD]) in 6 countries (that is Argentina, Brazil, Mexico, Chile, Colombia and Panama); and to profile the treatment landscape of Latin American MM participants, including factors associated with health-care provider (HCP) selections of different treatment regimens. These factors can include a participant's demographic and clinical characteristics and availability of different therapy options per institution in each country.
