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 study evaluates the effect of an open-label placebo intervention on cycling time-trial performance.
In recent years there has been a growing number of procedures for the removal of the buccal fat pad (BFP) or as frequently referred to as bichectomy. Buccal fat pad removal can be used as part of the therapeutic procedure in cases of: sinus buco fistulas, peri-orbital defects, congenital palatal fissure, patients with severe bruxism, patients with constant lesions caused by bites on the jugal mucosa and in patients who are dissatisfied with the facial contour. In cases of thinning of the face, biting lesions and bruxism, total or partial of the BFP removal is performed, always taking into account a facial harmonization. The aim of the present study was to demonstrate the procedure of BFP removal and its respective postoperative period. A total of 40 BFP removal surgeries were performed between 2016 and 2017 with intraoral access technique. After the bichectomy procedure the subjects were followed for: 4, 7, 10, 15, 30, and 90 days. The postoperative period can be compared to that of a third molar extraction, and the use of analgesics and anti-inflammatories can adequately control the pain symptomatology. Edema and mouth opening limited for about 15 days were the most commonly found alterations in surgeries performed. The surgical technique is a simple and safe procedure provided by trained and experienced professionals. The bichectomy should be performed following a precise indication and the procedure is becoming a new area of practice for the dental surgeon, who can perform the procedure safely, reliably and with aesthetic and therapeutic results provided that with precise indications.
Halitosis is the term used to define an unpleasant odor emanating from the mouth. Some lung diseases, such as bronchiectasis, are among the extra-oral causes of this condition. However, no studies have evaluated the reasons and treatment of halitosis in the population of adults with bronchiectasis. Methods and analysis: A randomized, controlled trial is proposed. Halitosis will be evaluated based on the measurement of volatile sulfur compounds (VSC) using gas chromatography. The participants (n=40) with halitosis and bronchiectasis will be randomized into two groups: G1-treatment with photodynamic therapy (n = 20) or G2-cleaning of the tongue with a tongue scraper (n = 20). After the treatments, a second evaluation will be performed, along with a microbiological analysis (qPCR) for the identification of the bacteria P. gingivalis and T. denticola. If the halitosis persists, the participants will receive periodontal treatment. The evaluation of halitosis and the microbiological analysis will be repeated. If the halitosis is solved, the participants will return after three months for an additional evaluation. This protocol will determine the effectiveness of phototherapy regarding the reduction of halitosis in healthy older adults and those with bronchiectasis.
The purpose of this study is to evaluate the vaccine efficacy (VE) of a heterologous vaccine regimen utilizing Ad26.Mos4.HIV and aluminum phosphate-adjuvanted Clade C gp140 and Mosaic gp140 for the prevention of HIV-1 infection in HIV-1 seronegative cis-gender men and transgender individuals having sex with cis-gender men and/or transgender individuals.
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.
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.
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.
