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 (also known as IMpassion050) will evaluate the efficacy and safety of atezolizumab compared with placebo when given in combination with neoadjuvant dose-dense anthracycline (doxorubicin) + cyclophosphamide followed by paclitaxel + trastuzumab + pertuzumab (ddAC-PacHP) in patients with early HER2-positive breast cancer (T2-4, N1-3, M0).
This study evaluates the addition of continuous infusion of lidocaine or continuous infusion of magnesium sufate in the duration of spinal anesthesia.
The aim of the present study is to test the hypothesis that voluntary pelvic floor muscle pre-contraction (the Knack) (alone) can be a treatment for urine leakage during efforts. For this purpose, the following parameters will be analysed and compared amongst 1) the Knack, 2) pelvic floor muscle training and 3) the Knack + pelvic floor muscle training groups: urine leakage as assessed by the pad test, urinary symptoms, muscle function, quality of life, subjective cure, adherence to exercises in the outpatient setting and at home and perceived self-efficacy of pelvic floor muscle exercises. The study population will comprise women with mild to moderate stress urinary incontinence or mixed urinary incontinente (with predominant stress urinary incontinence) as assessed by means of the one-hour pad test (leakage ≥2 g). Leakage up to 10 grams will be rated mild stress urinary incontinence and of 11 to 50 grams as moderate stress urinary incontinence. The sample will also include women with grade 2 muscle strength (normal contraction with elevation of the anterior vaginal wall) on the two-finger assessment rated according to the Oxford scale. The primary outcome measure will be the objective cure of urinary incontinence as assessed by means of the one-hour pad test three months after randomization. Secondary outcome measures: three-day bladder diary, 1 hour pad test, International Consultation on Incontinence Questionnaire - Short Form, Incontinence Quality of Life Questionnaire, Subjective cure of stress urinary incontinence, Self-efficacy/outcome expectation to pelvic floor muscle exercises, Frequency of the outpatient sessions, adherence to home exercises and pelvic floor muscle function, morphometry, strength and vaginal squeeze pressure.
This study is design to assess two levels of dietary sodium intake in the treatment of patients with Acute Decompensated Heart Failure.
HPV-303 is a prospective, randomized, double-blind, placebo-controlled phase 3 study of VGX-3100 delivered intramuscularly (IM) followed by electroporation (EP) delivered with CELLECTRA™ 5PSP in adult women with histologically confirmed high-grade squamous intraepithelial lesions (HSIL) (cervical intraepithelial neoplasia grade 2 [CIN2] or grade 3 [CIN3]) of the cervix, associated with HPV-16 and/or HPV-18.
Prospective, multinational, multicentre, observational cohort study of neonatal sepsis in partner institutions. The cohort study will be designed to evaluate health care utilization and current clinical practice and to assess risk factors for and outcomes of babies with neonatal sepsis (culture-negative and culture-positive).
The aim of this research was to assess the impact of Oral Health-Related Quality of Life (OHRQoL) on children and their families affected by Traumatic Dental Injury (TDI) after insertion into a Dental Trauma Care Program (DTCP). After a sample size calculation, this non-randomized clinical study was composed of a consecutive sample of 2 to 6-year-old children registered in the DTCP from 2012-2019. Parents/Caregivers were interviewed to fill up an OHRQoL questionnaire. The Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) was applied (in form of an interview) to evaluate the impact of TDI on OHRQoL before, and after treatment. The scores of the B-ECOHIS were calculated using the additive method, summing the numeric response codes for each item. The Andreassen classification was used to determine the TDI. The patients were treated (minimally intervention/invasive intervention) according to TDI severity (uncomplicated/complicated). The Kolmogorov-Smirnov test was performed to evaluate the normality of the data to determine the use of parametric or non-parametric tests. Mean or median comparisons were made for items in the overall scale and subscale scores to compare B-ECOHIS total scale/subscales/domains before and after insertion in DTCP. The responsiveness was assessed by analyzing the change in the scores on the scales and subscales. The changes were calculated by subtracting the post-treatment scores from the before-treatment scores. Positive change scores indicate an improvement in OHRQoL, while negative scores indicate deterioration. TDI severity and treatment-associated were also evaluated.
A multi-center, national prevalence study where: (1) baseline SPIVC therapy complications of hospitalized adult patients that meet the inclusion/exclusion criteria of the study and (2) the compliance of clinicians to the Hospital's evidence based practice will be measured in Brazil.
Chronic low back pain interventions may include exercises, manual therapy, health education, and pain education, strategies based on psychological or behavioral change approaches, as well as biopsychosocial interventions. Pain self-management programs basically aim to engage the participant in activities, stimulating the patient to be more active in life and live despite the pain. However, pain neuroscience education is a new approach recognized as therapeutic patient education (ETP) and is best described as a form of cognitive rather than behavioral therapy. However, there are few studies in the literature comparing those types pain education. Thus, the purpose of this study will be to compare the immediate effects of an educational program focused on Pain Neuroscience Education vs. Pain self-management educations for patients with chronic low back pain considering the outcomes of pain intensity, catastrophizing and pain self-efficacy.
It is known that the low back pain can cause discomfort and deconcentration during the flight, requests for abstention of flight, fear in the aviators about the future in case of illness and economic damages to the country. However, there are few studies about the incidence, prevalence or risk factors associated with low back pain in Brazilian air force pilots. Also, the literature lacks further randomized controlled studies about interventions, leaving a huge field to be explored in future research. Objectives: This study to analyze the chronic effects of an exercise protocol on lumbar pain in Brazilian Air Force pilots. Materials and methods: The study is a blind and randomized clinical trial, in which a protocol of strength and lumbar resistance exercises will be tested. The volunteers will be: 20 fighter instructors with intermittent low back pain. Such volunteers will be recruited in a non-probabilistic manner for convenience. Moreover, they will be randomly distributed through www.randomization.com to form two groups with 10 members each: experimental group (EG), where they will participate in an exercise program three times a week for 8 weeks; and the control group (CG), in which they will receive explanation and handbook demonstration of the same exercises (Appendix 1) - after 8 weeks of intervention and after being reevaluated. The study will be performed at the city of Natal/ Rio Grande do Norte. The evaluation will consist of an evaluation form with personal data, anthropometric data, occupational information, health history, physical exercise pattern and pain information, quantified by Visual Analog Pain Scale. In addition, the Oswestry questionnaire will be administered to assess lumbar function and the Nordic Questionnaire to assess musculoskeletal changes. Also, will be done: postural evaluation, using a postural evaluation software (SAPO); assessment of lumbar range of motion, using an IPHONE app called iHandy Level; Magnetic Resonance Imaging of the spine; dynamometry to measure the trunk extension force, flexion with rotation and lateral bridge, using the manual dynamometer Lafayette® - model 01165, USA; and resistance test of trunk stabilizing muscles. Magnetic resonance imaging will be done at the Onofre Lopes University Hospital. The project will be submitted to the Research Ethics Committee of the Federal University of Rio Grande do Norte through the national interface "Plataforma Brasil". The study will also be registered on the international clinical trial platform, ClinicalTrials.gov. Data analysis: The Statistical Package for Social Science (SPSS) software will be used in the analysis. The normality of data distribution and the homogeneity of the variances will be verified by the Kolmogorov-Smirnov (K-S) and Levine tests, respectively. If there is a normal distribution, the descriptive statistics will be performed through means and standard deviations. Significance level adopted: 5% (P <0.05). The paired t test was used for the comparisons between the measurements obtained in the pre and post 2 month evaluations, and for the comparison between the groups (CG and EG), the unpaired t test. If the data do not present a normal distribution, the Friedman test will be used for comparisons of the measures of the evaluations in each group and the Kruskal-Wallis test for comparisons between the groups (CG and EG).
