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 research is to study an investigational medical device that is designed to produce lung volume reduction in diseased areas of the lungs in patients with severe emphysema.
Evaluation of oral midazolam to improve children's behavior and reduces the stress and anxiety during dental treatment
Aim: To determine the effects of pelvic floor muscle training (PFMT) in women with a single delivery route. Pregnancy and delivery route alter the pelvic floor muscle strength and are considered risk factors for urinary incontinence and genital dystopias. Methods: A Randomized controlled clinical trial with two hundred ninety-seven women aged 35 to 45 years old were selected for functional assessments of their pelvic floors by vaginal digital palpation and perineometry. One hundred sixty-five (69.7%) exhibited muscle strength deficits and were included in the clinical trial. The participants were distributed into two groups based on the delivery route (A, vaginal delivery and B, cesarean delivery) and were then randomly subdivided into Groups A1 (n = 44) and B1 (n = 42), who performed PFMT, and Groups A2 (n = 39) and B2 (n = 40), who did not undergo muscle training. The PFMT involved perineal contraction exercises in the dorsal decubitus, sitting, and standing positions and was applied twice per week for a total of 15 sessions. The functional assessment of pelvic floor by vaginal digital palpation and perineometry was performed after 15 sessions of pelvic´s floor muscles training. The statistical analysis was performed using the Mann-Whitney and Z tests at a 5% level of significance.
The purpose of this study is to allow continued use of pasireotide in patients who are on pasireotide treatment in a Novartis-sponsored study and are benefiting from the treatment as judged by the investigator.
Transradial approach (TRA) reduces vascular complications and access related-bleeding compared to transfemoral approach (TFA). However, this technique has been related to higher radiation exposure during coronary angiography and percutaneous coronary intervention. Previous studies have shown that TRA demands a long learning curve, and procedure success rate increases with operator's experience. Our hypothesis is that the higher radiation exposure during TRA is not a technique issue, but due to operator's expertise. The aim of this study is to evaluate whether experienced operators with either TRA or TFA can perform diagnostic coronary angiography with similar radiation exposure.
The main purpose of the study is to evaluate the efficacy and safety of the study drug known as prasugrel for the reduction of Vaso-Occlusive Crisis events in pediatric participants with sickle cell disease. The study will also investigate reduction in daily pain in children who have sickle cell disease.
This study has the following objective: To identify related factors to hospital mortality in patients with ST-segment elevation acute myocardial infarction submitted to pharmacoinvasive strategy within a structured healthcare network.
Justification and background Ventilator-associated complications (VACs) are those complications that develop during a period of intubation of a patient . Pneumonia is the second most frequent infectious complication in the hospital, and ranks first in ICU, whose risk is increased more than 20 times by the presence of invasive mechanical ventilation and is called ventilator-associated pneumonia (VAP) . Whereas the information published regarding VAP in terms of diagnosis, treatment and impact on the outcome of critically ill patients is enormous.Ventilator-associated tracheobronchitis (VAT) incidence is lacking and complicated in part, since the definition remains controversial. In addition, the significance of tracheobronchial colonization as a risk factor for subsequent lower respiratory tract infection remains unclear . The upper and lower airways can become colonized . Several factors have been taken into account and do not differ from those involved in VAT and VAP development in patients under mechanical ventilation. Definition VAT diagnosis is controversial and represents an actual problem in order to define the real incidence of VAT , There is currently no valid, reliable definition for VAT, and even the most widely-used VAT criteria and definitions are neither sensitive nor specific. The diagnosis of VAT is considered when a patient under invasive mechanical ventilation starts with fever, leukocytosis and new or increased purulent secretions by the endotracheal tube. A particular difficulty with much commonly used VAT definition (in order to distinguish from VAP) is the key point of the absence of pulmonary consolidation. Evidence suggests that chest radiograph findings do not accurately role out VAP. A taskforce on hospital-acquired pneumonia, and VAP has been recently published (European Respiratory Society (ERS), European Society of Clinical Microbiology and Infectious Diseases (ESCMID) and European Society of Intensive Care Medicine (ESICM)). Nosocomial tracheobronchitis definition includes occurrence of purulent tracheal secretion after ≥48 h of hospitalisation or mechanical ventilation plus ≥2 of the following: fever (≥38.5°C) or hypothermia (<36°C), leukocytosis (≥12 × 109/L), significant bacteriologic counts in respiratory secretions (≥103 cfu/mL for protected brush specimen (PBS) and ≥105 cfu/mL for endotracheal aspirates); absence of new pulmonary infiltrates compatible with pneumonia and absence of other causes of fever are mandatory. This definition needs to be further validated and can overdiagnose the incidence of VAT (and overuse of antibiotics) because the positive culture of respiratory secretions is not a mandatory item RATIONALE Given the possible high incidence of VAT, and its importance as a risk factor for VAP, and a potential target to treat in order to reduce VAP incidence, a large multicentre
Depressive elderly individuals have showed higher basal level of cortisol and lower level of dehydroepiandrosterone (DHEA). Moreover, changes on these hormone levels have also observed in reactivity of an acute stress, such as physical exercise. On the other hand, physical training can modulate the release of these hormones. Therefore, depressive elderly individuals physically actives might show attenuated reactivity of an acute physical stressor compared to sedentary elderly individuals. The aim of these study is to compare the effect of an acute physical stressor on cortisol levels in depressive and healthy individuals, physically actives and sedentaries. Additionally, the sulfated form of DHEA (DHEAS) serves as a reservoir for DHEA, because of that it is expected that DHEAS levels might reduce after the acute physical exercise.
Aging causes anatomical and physiological changes in the respiratory system and respiratory muscle strength with decline in its maximum function. This study aimed to evaluate the effects of inspiratory muscle training on respiratory muscle strength, thickness of the diaphragm and diaphragmatic mobility in older women. The investigators' hypothesis is that inspiratory muscle training improves respiratory muscle strength, the thickness of the diaphragm and diaphragmatic mobility in older women.
