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.
Aim: The aim of this randomized clinical trial is to evaluate the use of the porcine acellular dermal matrix (PADM) for the treatment of RT1 localized gingival recessions. Material and methods: Forthy patients (n=20) with RT1 localized gingival recessions with height ranging from 3 to 5 mm with and at least, 2mm of keratinized tissue width will be selected to participate in the study. Patients will be allocated randomly in two treatment groups: Coronally advanced flap (CAF) or coronally advanced flap associated with the porcine acellular dermal matrix (CAF+ PADM). The clinical parameters evaluated at the baseline, 6 and 12 months will be: Plaque index (IPL); gingival index (GI); relative gingival recession height (RGRH); gingival recession width (GRW); probing depth (PD); relative clinical attachment level (RCAL); keratinized tissue height (KTH); keratinized tissue thickness (KTT); papilla height (PH). Evaluations will be made by the professional and the patient regarding dentin hypersensitivity (HD) (Schiff and VAS scales respectively), aesthetics (RES and VAS scales, respectively) and patient's centered outcomes, through the questionnaire referring to the OHIP-14. Descriptive statistical analysis will be expressed as mean ± standard deviation (SD), median, quartiles, percentages and confidence intervals (95% CI). To analyze the normality of the residue, the Shapiro-Wilk test will be performed. Then, the Wilcoxon test will be applied to compare the periodontal parameters and a quality of life, before and post-treatment. Correlations between parameters and dental hypersensitivity will be analyzed through Spearman's test. Key words: Gingival recession, Root coverage, Biomaterial, Acellular dermal matrix.
A retrospective study evaluating AKI patients in whom RRT was interrupted for at least 48 hours. Patients who were still RRT-independent 7 days after initial RRT cessation were included in the "Success" group, as opposed to the "Failure" group. Baseline characteristics and variables at the time of RRT interruption were collected. Multivariable analysis was performed and a model was generated to evaluate the prediction of success.
Transgender women (TW) are a key population and priority for HIV treatment. More research is needed to develop evidence-based clinical guidance when it comes to choosing antiretroviral treatment (ART) regimens for TW on feminizing hormonal therapy (FHT). Concerns about ART interacting with FHT and decreasing its effectiveness can lead to decreased ART adherence and increased viral loads. The GET IT RiGHT trial aims to address concerns about drug-drug interactions (DDIs) between ART and FHT while providing access to hormonal therapy to TW living with HIV. Data suggest that access to FHT improves adherence to HIV treatment and decreases treatment interruptions. This is an open-label, non-randomized, 3-group trial of adult TW and other individuals identifying as female or transfeminine but with male sex assigned at birth living with HIV. Participants will be on ART at entry and receive study-supplied 17-β estradiol for FHT for 48 weeks. The primary objectives of the study are to 1) assess whether TW continue to achieve therapeutic concentrations of ART while receiving FHT for 48 weeks and 2) assess whether serum estradiol concentrations on FHT (across a range of estradiol doses) vary between boosted and un-boosted ART regimens.
The goal of this clinical trial is to evaluate the effect of spironolactone in the primary prevention of cardiotoxicity in cancer patients who are undergoing chemotherapy with anthracycline within 12 months. The main question it aims to answer is: • Does spironolactone reduce the incidence of cardiotoxicity in patients undergoing anthracycline chemotherapy? Participants will: - Be cancer patients over 18 years starting treatment with anthracycline; - Be randomized to receive either spironolactone or a placebo for 1 year; - Undergo assessments of their left ventricular ejection fraction (LVEF), global longitudinal strain, and cardiac biomarkers over the 12-month period. Researchers will compare the spironolactone group to the placebo group to see if cardiotoxicity incidence differs between the two.
Citrus bioflavonoids, such as eriocitrin, hesperidin and naringin, have been shown improved hyperglycemia, insulin resistance and systemic inflammation, related to the development of type 2 diabetes. The nutraceutical Eriomin, a lemon flavonoid extract composed mainly by eriocitrin (70%) and other flavonoids (30%), improved the control of moderate hyperglycemia in pre-diabetic and diabetic patients without drug therapy. However, most patients with pre-diabetes are on oral biguanide (metformin) therapy, despite its limited efficacy (30-40%) on glycemic control and its undesirable gastrointestinal effects. Therefore, in the current study, Eriomin will be administered at a dose of 250 mg/d to adults diagnosed with pre-diabetes and being treated with metformin (1,000 mg/d). This clinical trial was designed as a placebo-control, double-blind, two-arm, crossover design. Clinical characteristics, body composition, food consumption, metabolic and inflammatory biomarkers and the microbiota of all patients will be evaluated before, during and at the end of the 12-week period (arm). Biochemical and metabolic parameters associated with prediabetes are expected to improve or return to normal with Eriomin in combination with metformin. At the same time, an increase in beneficial intestinal bacteria is expected, reducing pre-diabetic dysbiosis, and perhaps a noticeable improvement in body composition.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of BMS-986278 in participants with Idiopathic Pulmonary Fibrosis.
This is a phase I/II, randomized, double-blind, placebo-controlled clinical trial that will evaluate the safety and potential efficacy of therapy with extracellular vesicles (EVs) obtained from mesenchymal stromal cells (MSCs), patients with moderate to severe acute respiratory distress syndrome due to COVID-19 or other etiology. Participants will be allocated to receive EVs obtained from MSCs or placebo (equal volume of Plasma-Lyte A). Blinding will cover the participants, the multidisciplinary intensive care team and the investigators.
Cervical cancer is a relatively common cancer among women living with human immunodeficiency virus (HIV). This study will test women for human papillomavirus (HPV) infection of the cervix. The main purpose of this study is to determine the best way to test for damaged areas of the cervix. Damaged areas of the cervix should be treated and removed to prevent cancer of the cervix. Women in this study will be seen once, twice or three times in a year. Women will provide several samples related to screening for cervical cancer including a swab of the cervix, a self-collected swab of the vagina and urine. Women will have a detailed examination of the cervix called colposcopy and have a few biopsies, or small pinches of the cervix, to look for areas at risk for turning into cancer. If HPV of the cervix is found but treatment of the cervix is not indicated, women will return in 6 months and in 12 months to repeat these tests. Most women will only need 1 visit. Women found to have damaged areas of the cervix at risk for turning into cancer will be referred for treatment. This protocol will compare different tests to understand the best test to identify women at risk for cervical cancer.
This project is composed of a phase I study with the purpose of evaluating adverse reactions and the best dose to be used of Sm29 and a phase II randomized controlled study with 3 arms with the purpose of comparing the efficacy of meglumine antimoniate associated with Sm29, with meglumine antimoniate plus placebo and meglumine antimoniate alone in the treatment of cutaneous leishmaniasis.
The aim of this study was to verify whether prostaglandin analogue (PA) eye drops influence the retinal thickness of glaucomatous patients undergoing trabeculectomy (TRAB) surgery. We selected eyes of patients with glaucoma with surgical indication for TRAB who were using PA eye drops and without previous retinal alterations, from the Centro de Referência em Oftalmologia (CEROF) from the Federal University of Goiás and Fundação Banco de Olhos de Goiás (FUBOG). Patients were divided into 2 groups: the study group (SG) and the control group (CG). In the CG, the PA was suspended between 30 and 60 days before the preoperative exams were performed (maximum of 15 days before surgery for both groups). All patients included were submitted to various eye exams before the procedure, and postoperatively on 3 occasions: 1 to 3 days ("PO1"), 6 to 9 days ("PO7") and 27 to 30 days ("PO30") after surgery.
