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.
Before February 2018 the baseline survey is conducted in about 60 class in Brazilian secondary schools. These classes are randomized to control and intervention group in a 1/1 manner. A few weeks thereafter medical students from the local medical school visit the schools and perform a smoking prevention intervention called "photoaging mirroring intervention" which takes about 45 minutes. One month and six months after the intervention the intervention group receives another anonymous questionnaire monitoring smoking status. The primary endpoint is the difference in the chance of smoking prevalence between the two groups.
The aim of this study is to assess if hypogonadic men with periodontitis benefit from testosterone replacement therapy before being submitted to periodontal treatment. Fifty hypogonadic men (Total Testosterone <200ng/dL) will be recruited from the Clinics Hospital at Federal University of Paraná and subjected to periodontal evaluation by a trained and calibrated researcher. The subjects presenting with periodontitis (assessed by clinical parameters) will be randomly allocated to "testosterone replacement therapy" (TRT) group or "placebo" for 3 months. After that time, all patients will receive nonsurgical periodontal treatment, which will be reassessed after 45 days. Clinical parameters (such as probing depth, gingival and plaque index, clinical attachment loss, bleeding on probing), sub gingival plaque and gingival crevicular fluid will be collected at baseline, just before therapy and 45 days after therapy.
Fear and dental anxiety are often associated with the use of needles and syringes for local anesthesia, and painful perception during the administration of local anesthetics is often the main reason for anxiety behaviors and defensive reactions. Dental trauma originates in childhood, through experience misconduct. The objective of this study is to evaluate the pain and anxiety related to 4 different modalities of anesthesia in children. Will be selected volunteers aged between 5 and 12 years who need restorative dental treatment in posterior teeth in the upper 2 quadrants. All patients will receive 1 modality of anesthesia: conventional anesthesia (control group), computerized anesthesia, Dental Vibe anesthesia and computerized anesthesia + DentalVibe anesthesia. Evaluations will be made with physiological and behavioral criteria. For the physiological evaluation will be measured the blood pressure, respiratory rate, heart rate, oximetry and salivary cortisol before and during each anesthesia. As criteria for evaluation of anxiety will be applied the methods, Corah and modified VPT before anesthesia and modified VPT will be repeated after anesthesia. The pain will be assessed at the end of each anesthesia with Visual Analogue Scale (VAS) and Wong Baker Faces. The results will be submitted to parametric and non-parametric statistical analysis, according to the data obtained in the different evaluation criteria.
This study will evaluate the safety, tolerability, and efficacy of tedizolid phosphate (MK-1986) compared with comparator antibacterial agent in participants from birth to less than 12 years of age with acute bacterial skin and skin structure infections (ABSSSI).
Sexuality is considered one of the pillars of quality of life, an integral part of the personality of each individual. Being a basic human being need, it cannot be separated from other aspects of life. For several centuries and until recently, sexuality was considered the "lower instincts" expression related only to the sexual act. Sex is associated with "reproduction" of the sexual energy. On the other hand, the exercise of sexuality includes various factors such as the building of the sensitivity between individuals like touch, dance, fantasy, look, etc. For a long time feminine sexuality was predominantly focused on procreation and has only recently been considered as an integral part of sexual and reproductive rights of women. Vaginismus is a female sexual dysfunction that affects the quality of sexual and psychosocial lives of women, influencing the quality of the couple's relationship. The scientific literature emphasizes the importance of the examination, diagnosis and physical therapy for this dysfunction, but until now there is no quantification or evaluation of the pelvic floor muscles for this group of women, which justifies the realization of this project.
The presence of trigger points in the pelvic floor musculature (PFM) is a frequent condition in individuals with chronic pelvic pain (CPP) and is associated with higher levels of pain, disability and functional decline. The purpose of this study is to test the effectiveness of two interventions: pelvic floor muscle (PFM) training with biofeedback and PFM training with the addition of trigger point dry needling applied over(Lumbar square, psoas, external obliques, gluteus medius, piriformis and adductors) on pain and quality of life of women with CPP.
The objective of this clinical study is to assess the irritation and sensitisation potential of a cosmetic test product after repeated semi-occlusive patch applications to healthy human participants by following a conventional HRIPT methodology under supervision of a dermatologist.
Introduction: Osteoarthritis is a disabling disease that can affect 6% to 12% of the adult population and more than a third of people over 65 years of age. Considering osteoarthritis of hands, existing research about the therapeutic treatment advocates actions such as (1) joint protection, (2) assistive technology and (3) exercises, however, doubts persist as to their effects. Objective: To verify the functional and analgesic effect of joint protection and energy conservation techniques, assistive technology (orthotics and adaptations) and exercises in the treatment of patients with osteoarthritis of the hands. Method: An epidemiological study in which a total sample of patients with knee osteoarthritis will receive joint protection and energy conservation guidelines. Subsequently, the sample will be divided into two groups, group 1 with radiological signs that suggest osteoarthritis of the hands and 2 with patients with radiological signs and symptoms of osteoarthritis of the hands, who present greater functional limitations in the daily life, being eligible for treatment of Rehabilitation, in which will be used orthosis aiming at the relief of pain, stabilization of the affected joints and the prevention of grievance of deformities and orientations of exercises to maintain muscle strength. Participants will be followed up for two years, evaluated with the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), Stanford Health Assessment Questionnaire (HAQ), palmar grip strength measured with Jamar dynamometer, key pinch strength, three point pinch strength and pulp pinch strength measured with B & L Pinch-gauge dynamometer. The groups will be divided between 1 and 2, the group 1 will be composed of patients who will only perform the orientations informed in the theoretical and practical classes, while the group 2, besides the orientations will receive orthoses with models such as volar hand rest splints, short thumb stabilization splints, and volar finger splints with nocturnal support, aiming at the relief of the pain, stabilization of the affected joints and the prevention of the appearance / aggravation of deformities. Exercise guidelines for maintenance of muscle strength for thumb and fingers will be performed on patients who present significant improvement of pain.
Study AG120-C-009 is a global, Phase 3, multicenter, double-blind, randomized, placebo-controlled clinical trial to evaluate the efficacy and safety of AG-120 (ivosidenib) + azacitidine vs placebo + azacitidine in adult participants with previously untreated IDH1m AML who are considered appropriate candidates for non-intensive therapy. The primary endpoint is event-free survival (EFS). The key secondary efficacy endpoints are overall survival (OS), rate of complete remission (CR), rate of CR and complete remission with partial hematologic recovery (CRh), and overall response rate (ORR). Participants eligible for study treatment based on Screening assessments will be randomized 1:1 to receive oral AG-120 or matched placebo, both administered in combination with subcutaneous (SC) or intravenous (IV) azacitidine. An estimated 200 participants will take part in the study.
Postural control requires the integration of the vestibular, visual, and somatosensory systems. Vision, in particular, exerts a considerable influence on body sway during activities that require balance. The investigators aimed to analyze the effects of transcranial direct current stimulation (tDCS) combined with proprioceptive exercises on postural control in individuals between 18 and 55 years old, with congenital and acquired blindness. The intervention will occur in three phases: 1 - Determine differences in postural control and gait between individuals with congenital and acquired blindness with and without the use of a guide stick when wearing shoes and when barefoot; 2 - Will be a pilot study containing 10 subjects in each group (total of 40) where a sample size estimation will be analyzed based on a gait and balance parameters result from a ten consecutive days treatment protocol consisting of tDCS plus proprioceptive; 3 - A treatment protocol will be conducted in which the participants will be allocated to four groups: G1 - active tDCS + dynamic proprioceptive exercises; G2 - sham tDCS + dynamic proprioceptive exercises; G3 - active tDCS + static proprioceptive exercises; and G4 - sham tDCS + static proprioceptive exercises. Evaluations will involve a camera system for three-dimensional gait analysis, a force plate to measure the postural control, and electromyography to analyze the muscle activities. Dynamic stability will be determined using the Timed Up and Go test and static stability will be analyzed with the aid of the force plate. The viability of this study will allow the determination of differences in postural control between individuals with congenital and acquired blindness, the analysis of the effect of tDCS on postural control, and the establishment of a rehabilitation protocol.
