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 purpose of this study is to determine whether the investigational treatment (maralixibat) is safe and effective in pediatric participants with Progressive Familial Intrahepatic Cholestasis (PFIC).
Non-specific low back pain is a common condition. Insoles are one of the many treatment form for chronic nonspecific LBP. The investigators hypothesized the contact total insole group will present pain reduction and functional improvement. The aim of this study is to assess the effectiveness of contact total insole for people with nonspecific chronic low back pain and the impact of this insole on function, quality of life, load distribution in the plantar region, gait variables and satisfaction with insole use.
Today in Brazil, 6.9% of the population has Diabetes Mellitus 2 (DM2). In the world, there are about 422 million people with DM2. It is a chronic disease of the endocrine system, accounts for 90 to 95% of cases of DM2 and is characterized by defects in insulin action and secretion. Its main cause is linked to obesity and insulin resistance. Obesity is a chronic, multifactorial disease - environmental, nutritional and genetic factors - characterized by excessive accumulation of body fat, and is reaching epidemic proportions, more than 100 million children and 600 million adults worldwide. The number of obese people in Brazil reaches 17.9% of the population. Rates of obesity and DM2 have increased in the last decades, both diseases being associated with inflammation and specific alterations in the intestinal microbiota. Thus, studies show that the use of probiotics may be associated with reduced body weight and reduced glucose in the bloodstream. Probiotics are living microorganisms that, when administered in suitable dosages, confer benefits to the health of the host. In addition, studies show the relationship of the intestinal microbiota and the emergence of various diseases and demonstrate that probiotics can control inflammatory processes, metabolic dysfunctions, normalization of stress-induced behaviors, regulation of the hypothalamic-pituitary-adrenal axis and neuropsychiatric disorders. Thus, the importance of investigating the ingestion of probiotics in relation to anthropometry, biochemical profile and anxiety in diabetic and overweight individuals with cardiopathy are justified. It is a randomized, double-blind, controlled clinical trial. The study will last 3 months and will occur with 74 adult individuals (between 20 and 60 years) of the SUS outpatient clinic of the Institute of Cardiology of Porto Alegre - RS, of both sexes, with BMI above 25 m² / kg. and less than 40 m² / kg, divided into 2 groups and 37 individuals per group. These patients were: Group A (intervention: n = 37): patient received 1 sachet per day of probiotics Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus lactis, Bifidobacterium lactis and Bifidobacterium bifidum for 90 days and Group B (placebo; n = 37): microcrystalline cellulose, lactose, pregelatinized maize starch. Probiotics will contain a dose of 109 CFU in each strain. The excipients used will be: microcrystalline cellulose.
Combination therapy in pulmonary arterial hypertension (PAH) has been the subject of active investigation for more than a decade, with the benefit of targeting different pathways known to be involved in the pathogenesis of the disease. Adherence to prescribed therapy has an impact on clinical outcomes. Reducing the pill/tablet count and frequency has a major impact on patients' adherence to therapies and therefore the observed clinical outcomes. One way to simplify treatment is to use fixed-dose combination (FDC) products that combine multiple treatments targeting different pathways into a single tablet. This study aims to demonstrate that the FDC of macitentan and tadalafil is more effective than therapy with 10 mg of macitentan alone or 40 mg of tadalafil alone. This phase 3 study will evaluate the efficacy and safety at 16 weeks of an FDC (macitentan 10 mg and tadalafil 40 mg) against these two PAH-approved therapies given as monotherapy to further confirm the added value of the FDC.
The aim of this study is to compare en masse (EM) and two-step anterior teeth retraction (TSR) evaluated by means of three-dimensional images superimposition. Thirty-two adult patients with bimaxillary protrusion planed for treatment with four first premolar extractions will be enrolled. All patients will be randomly allocated in a 1:1 ratio to either EM (n=16) group or the TSR (n=16) group. Cone bean computed tomography will be taken before and after anterior retraction. A blind observer will construct separate 3D models for maxillary and mandibular surfaces using the anterior cranial fossa to register models of before and after space closing. Quantitative assessment of posterior anchorage loss and amount of anterior teeth retraction are the main outcomes. The secondary outcomes are the inclination of the molars, canines and incisors.
Among all cancers, lung cancer is the most common disease on the planet, accounting for 13% of the cases, and leading the number of deaths from malignant diseases. In Brazil, it is estimated that its incidence between 2018 and 2019 could be 18,704 new cases in men and 12,503,000 new cases in women. These data take into account an estimated risk of 18.16 new cases for 100,000 men and 11.81 for 100,000 women, respectively occupying the second and fourth most frequent cases of the disease according to gender . Surgeries, however aggressive they may be, are one of the most viable alternatives for patients with PC, provided it is performed in the milder or early phase of the disease, since after such period this procedure may have a period degree greater than the other forms of treatment. As a consequence, the injuries that the surgical procedure can cause to patients, pain is one of the most influential in the patient's quality of life. It can lead the individual to a marked state of disability both functional and psychological, thus being determinant for the suffering related to the disease, thus comprising its multifactorial character, involving physical, emotional, socio-cultural and environmental aspects . For the control of pain, physiotherapy appears with features such as transcutaneous nerve electrostimulation, where its use for the suppression of pain has become quite feasible due mainly to the ease of its handling, to be noninvasive and to serve to reduce acute pain and chronic. The use of conventional transcutaneous nerve electrostimulation to support the use of analgesics reduced the intensity of pain in patients of the second day of thoracotomy, but for a longer extension of their effects, it would take a longer time to apply the resource, something around 24 -48 hours.
Vitreoretinal surgery has evolved to less invasive procedures, and it is used to treat a wide range of diseases. So anesthesia for vitreoretinal procedures has evolved, promoting adequate analgesia while reducing risks to the patient. In the present study two types of procedures for anesthesia during vitreoretinal surgery are evaluated regarding the pain referred by the patient during the whole procedure: peribulbar anesthesia versus sub-tenon injection plus topical jelly anesthesia. Through the comparative analysis of the pain scale of the two groups it is expected that the two modalities present the same anesthetic efficacy, showing that the methods used may be equivalent.
One of the most challenging aspects of Pediatric Dentistry is the management of child behavior. Among the procedures performed, local anesthesia is one of the factors that influence the increase in fear and anxiety in children in relation to dental procedures. This study aims to evaluate the effect of the use of virtual reality glasses as an audiovisual distraction technique during anesthesia in behavior, anxiety and pain perception, comparing it with traditional behavior management techniques. A sample of 44 children was estimated and will be selected with the following inclusion criteria: be between 5 and 9 years of age; good general health; no prior dental experience involving anesthesia in the last 2 years; need for restorative treatment or exodontia under local anesthesia. Children with physical or mental disabilities will be excluded and those who report poor behavior in dental consultations will be excluded. The sample will be randomized with 22 envelopes for the group that will use the glasses during the procedure(G0) and 22 envelopes containing group that will not use the glasses in consultation (G1). The treatments will be performed in 2 visits, the first for initial examination, and the other for performing the procedures are either extraction or restorative treatment with the use of local anesthesia. During dental treatment, the dentist will explain the procedure in layman's terms using the basic techniques of behavior management, such as the "tell-show-do" technique, positive reinforcement, conventional distraction in all consultations. When using the distraction technique with virtual reality during the procedure, the virtual stereo glasses model HDMI-MHL 98 Inches (98') will be used. In all two consultations, VENHAM anxiety will be assessed through VENHAM scale and heart rate measurement at the beginning, during and at the end of the visit, as well as the perception of pain during the procedure (FLACC) and after finishing the service through the FPS-R scale. During the visits, the data will be collected using a previously tested tab. The data will be entered into a worksheet in the Microsoft® Excel® 2016 program and analyzed in the Stata 14.0 program. There will be a single blind blinding: both for the typist and who will analyze the data. A descriptive analysis of the data will be performed, obtaining the absolute and relative frequencies. Comparisons in the outcomes of interest between groups G0 and G1 will be performed using the chi-square test for dichotomous variables and the t-test for comparison of means. A significance level of 5% will be adopted for all analyzes.
The objective of this study was to evaluate the variability of the heart rate of exercise physicists with and without caffeine intake. Practitioners of resisted physical exercise, specifically bodybuilding, who are young adults between the ages of 18 and 30 will participate in the study. To define the sample size, a sample calculation was performed based considering as variable the RMSSD index (square root of the square mean of the differences between the adjacent normal iRRs). The significant difference magnitude assumed was 12 ms, considering a standard deviation of 16.2 ms, with alpha risk of 5% and beta of 80%. A minimum of 14 subjects per group were required in the survey. A total of 32 subjects will participate in the research, being these divided and allocated in different groups. Sampling will be of the intentional kind.
The reason for this study is to see if baricitinib is safe and effective in adults with severe or very severe alopecia areata (AA).
