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 this study is to evaluate clinical and patients-centered parameters of 3-month outcome of the enamel-derived matrix (EMD) application on wound healing process of the donor palatal area after free gingival graft (FGG) removal.
The aim of the study was to compare dental caries treatment and follow-up based on an elaborate and individualized assessment of caries risk in children, to a simpler risk assessment strategy by means of a double-blind randomized clinical trial of two years monitoring. Participants will be children from 7 to 11 years old, who pass through the screening of the Children's Clinic of the Faculty of Dentistry of the Federal University of Pelotas and fulfill the inclusion criteria. A randomized, stratified sample of approximately 250 children will be included in the study, one group will be composed of children undergoing dental caries-related treatment and maintenance, guided by an individualized and multivariate risk assessment, and another group of children treated based on dental caries experience alone in the deciduous and / or permanent dentition. Recruitment will begin at the beginning of 2019, and participants will be followed up for 24 months. Parents will respond to an anamnesis, 24-hour dietary recall, food frequency questionnaire, and oral and general health-related quality of life questionnaire, children will undergo a clinical examination to assess caries, according to the International Caries Detection and Assessment System (ICDAS) in its simplified form and evaluation of caries activity. Dental treatments and return intervals will be designated according to the individual risk of the patient detected in the initial approach according to the group. The study evaluations consist of baseline, 12 months and 24 months, data will be transferred to spreadsheets after the different phases of the study. Primary outcomes (number of dental surfaces requiring operative intervention) and secondary outcomes will be analyzed by Student's t test, quality of life and quality of life related to oral health, will be assessed at the beginning of the study and at the end of treatment, and compared between the groups.
The primary objective of the study is to compare disease-free survival (DFS) of patients with high-risk cutaneous squamous cell carcinoma (CSCC) treated with adjuvant cemiplimab, versus those treated with placebo, after surgery and radiation therapy (RT). The secondary objectives of the study are: - To compare the overall survival (OS) of high-risk CSCC patients treated with adjuvant cemiplimab, versus those treated with placebo, after surgery and RT - To compare the effect of adjuvant cemiplimab with that of placebo on patients' freedom from locoregional recurrence (FFLRR) after surgery and RT - To compare the effect of adjuvant cemiplimab with that of placebo on patients' freedom from distant recurrence (FFDR) after surgery and RT - To compare the effect of adjuvant cemiplimab with that of placebo on the cumulative incidence of second primary CSCC tumors (SPTs) after surgery and RT - To evaluate the safety of adjuvant cemiplimab and that of placebo in high-risk CSCC patients after surgery and RT - To assess cemiplimab pharmacokinetics and immunogenicity in human serum
Cachexia is a very common condition in patients with advanced heart failure (HF) and is considered a predictor of mortality. Studies have been carried out in an attempt to discover the mechanisms that leads to cachexia in order to improve the therapies and the survival of these patients. Some of these studies give the hypothesis that the gastrointestinal tract, more precisely the intestine, can collaborate with cachexia. Some of these studies suggest that, the intestinal mucosa, due to hypoperfusion, becomes more permeable to some substances, as like endotoxins, being the lipopolysaccharide (LPS) one of them. The circulating LPS can stimulate the increase of tumor necrosis alpha (TNF-alpha) further increasing the inflammation and, consequently, contributing to the worsening of prognosis. The intestinal microbiota is also affected by hypoperfusion, contributing with increase of permeability. As known, probiotics can help to maintain or recover the microbiota and maintain a healthy intestinal barrier. In view of the importance of microbiota to inflammation in the prognosis of the patients and the performance of microbiota in maintenance of intestinal barrier, this study has as primary objective to verify the influence of supplementation of the probiotic Lactobacillus acidophilus (LA) in the lowering of serum levels of TNF-alpha in the patients with HF.
Multinational, investigator-initiated study of oral anticoagulation versus no anticoagulation for the prevention of stroke and other adverse cardiovascular events in patients with transient perioperative atrial fibrillation after noncardiac surgery and additional stroke risk factors.
This study aims to evaluate the possible effect of melatonin on prevention of cognitive dysfunction in the postoperative period of elderly patients undergoing transurethral resection of the prostate (TURP) under spinal anesthesia
Pectoral nerve block provides a good alternative to epidural or paravertebral block with a lower risk for the patient and that is shown as an optimal anesthetic option with reduction in postoperative pain, anesthetic and opioid consumption. The main objective of this study is to evaluate the quality of the perioperative analgesia of the PECS block in patients electively escalated for the accomplishment of mastectomy under general anesthesia.
Chronic postoperative pain is an entity that is usually neglected by anesthetists, but several studies show that the choice of anesthetic technique may interfere with this prevalence. Esmolol is a selective beta-blocker of ultra fast duration that has been studied as a perioperative venous adjuvant with antihyperalgesic and opioid sparing action. The investigators ventured the possibility of this anti-hyperalgesic effect attenuating the chronic pain syndrome post-mastectomy.
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%.
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.
