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.
Objective: To assess the influence of nebulization with bronchodilators carried by the heliox coupled to PEP in the distribution of compartimental lung volumes in asmathic adults and to correlate with pulmonary function data. Methods: A controlled randomized trial involving 27 patients divided into four groups: heliox + PEP, oxygen + PEP, heliox and oxygen. After the initial evaluation, it was placing 89 reflective markers attached to the surface of the trunk and images acquired by optoelectronic plethysmography (OEP) of six cameras. Three slow vital capacity maneuvers and quiet breathing regarded as phase control. After the control phase, all patients underwent nebulization with a distribution noninvasive system, semi-closed using 10 drops of Fenoterol Bromide and 20 drops of Ipratropium.
This was a three-arm, randomized, open label, multi-center phase II study investigating the combination of everolimus (10mg daily) with exemestane (25mg daily) versus everolimus (10mg daily) versus capecitabine (1250mg/m2 twice daily for 14 days, 3-week cycle) in patients with estrogen-receptor positive, HER2 negative, advanced breast cancer after recurrence or progression on letrozole or anastrozole.
Premenstrual syndrome (PMS) is a collection of physical and emotional symptoms related to a woman's menstrual cycle. These symptoms occurring only during the luteal phase of the menstrual cycle that are of sufficient severity to interfere with some aspects of life of these women, reflecting also in interpersonal relationships, workplace and in their productivity. For these reasons, this research was conducted with the nursing staff of the Samaritan Hospital in order to verify the effectiveness of auricular acupuncture to alleviate some of the symptoms of PMS.
The purpose of this study was to evaluate the safety and pharmacokinetics (PK) of raltegravir (RAL) when given to HIV-1-exposed, normal birth weight newborn infants at risk of acquiring HIV-1 infection. (PK is the study of the time course of absorption, distribution, metabolism, and excretion of drugs in the body.) The primary goal of this study was to determine a dose of RAL that was safe and met the PK targets for infants when administered during the first 6 weeks of life in addition to standard of care antiretroviral (ARV) agents for prevention of perinatal transmission.
Up to this moment, the majority of studies assessing the level of physical activity in daily life in patients with COPD are limited to a cross-sectional design, which does not take into account natural variation of physical activity in daily life due to differences in climatic conditions faced throughout the year. Preliminary evidences suggest that patients with COPD have different physical activity levels according to the seasons of the year. However, the limited current evidences do not allow us to know the magnitude of differences in the level of daily physical activity in patients with COPD when taking into account climatic changes resulting from different seasons of the year in cities and countries with contrasting climatic conditions. This gap observed in the literature does not allow us at this moment to know whether we should or not consider the season of the year as one of the main causes of variability while assessing physical activity in daily life in patients with COPD. The present project proposes to investigate the hypothesis that patients with COPD who live in a place with less marked decrease in temperature between summer and winter (Londrina, Brazil) have less variability in the level of physical activity in daily life through the year in comparison to patients who live in a place with more marked climatic variability during these seasons (Leuven, Belgium).
Bruxism is a parafunctional habit characterized by grinding and/or clenching of the teeth. It may happen while awake (awake bruxism) or while sleeping (sleep bruxism). In adults, the prevalence is 20% for the awake bruxism and 8% for the sleep bruxism. Peripheral, central, and psychosocial factors influence the disorder, which may predispose to pain in the masticatory muscles and neck, headache, decreased pain thresholds in the masticatory and cervical muscles, limitation mandibular opening, sleep disorders, stress, anxiety, depression, and overall impairment of oral health. The aim of this study is to compare physical therapy interventions with dental treatment in pain, mandibular opening, sleep quality, anxiety, stress, depression, and oral health in individuals with bruxism.
The investigators will test the hypothesis that transcutaneous electrical nerve stimulation (TENS) may attenuate peripheral vasoconstriction and to improve blood flow redistribution during handgrip exercise in acute myocardial infarction (AMI) patients after Coronary Arterial Bypass Graft Surgery (CABG).
Whether the lower immunogenicity of the mumps component obtained in clinical studies with the MMR in Brazil, due to the multidose presentation. Investigations were made on factors that could interfere with immunogenicity of mumps component, as the kits used for the immunoassay method, and potency of the vaccine, but no explanation was found. This study aimed to investigate the hypothesis that the lower immunogenicity of the mumps component of the MMR Bio-Manguinhos vaccine, is due to the multidose presentation. The Main objetctive is evaluate the immunogenicity of MMR after one dose in children 12 to 23 months of life, comparing the performances multidose vial (10 doses per vial of vaccine produced in Bio-Manguinhos/Fiocruz through technology transfer from GlaxoSmithKline Laboratory - GSK) and single dose vial (1 dose per vial of vaccine produced by GSK).
Gastrointestinal (GI) complications after renal transplantation are commonly reported as side effects of immunosuppressive agents. Despite this, motility disorders have been scantily studied. Alternating Current Biosusceptometry (ACB) are biomagnetic sensors designed for a wide range of applications. In clinical practice, their non-invasive and radiation free features provide an excellent approach for monitoring of GI transit as alternative to scintigraphy and breath tests. The aim of this study is to examine GI transit and motility of solids in stable renal transplant recipients to determine the potential influence of immunosuppressive therapy on gastrointestinal parameters.
The appropriate management of postoperative pain is recognized as an important clinical challenge with implications beyond humanitarian issues. Evidence shows that effective postoperative analgesia is associated with physiological benefits to the patient, shortened length of hospital stay and lower rates of in-hospital complications, such as pneumonia, delirium and persistent pain after surgery. However, despite the availability of several analgesic drugs and strategies the prevention and treatment of postoperative pain is often suboptimal. Remifentanil is a potent short acting opioid commonly used in continuous infusion for anesthesia for several surgical procedures. Remifentanil has been extensively advocated as a means to provide quick patient awakening in the immediate postoperative period with a very low risk of respiratory depression. Yet it does not provide residual analgesia and postoperative pain is a major concern. In order to overcome this limitation, practicing anesthesiologists frequently give patients a single dose of Sufentanil, a long acting opioid, during the induction of anesthesia where Remifentanil will be used in continuous infusion. However the effectiveness of this strategy still lacks evidence from controlled clinical trials.
