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.
Introduction: Patients on mechanical ventilation suffer alterations in the viscoelastic characteristics of the mucus due to changes in the humidity and temperature of the inhaled air and in the respiratory volumes and flows. The literature has pointed out the use of mechanical ventilators as a tool for mobilizing secretions and closed-system aspiration associated with expiratory pause has been shown to be effective in mobilizing secretions. Objectives: To assess whether there is a difference in the mass of aspirated secretion with the application of the expiratory pause during aspiration. Methods: A crossover, randomized study. Applied to children aged 0 to 5 years and 11 months who are intubated for 24 hours with orotracheal tubes or tracheostomy. There will be an exclusion of patients who present with undrained pneumothorax, cranial hypertension or any other clinical situation that has a clinical contraindication to aspiration and patients whose parents do not agree to participate in the study. The technique will be during aspiration in the tube with where to apply or not the expiratory pause on the mechanical ventilator. This secretion will be weighed so that there is fidelity in the results.
The purpose of this study is to evaluate the effect of probiotic supplementation on fecal microbiota, nutritional status, metabolic and inflammatory parameters in patients with type 2 diabetes mellitus. Study hypothesis: Supplementation of multispecies probiotic (Bifidobacterium Lactis, B. brebe, B. longum, Lactobacillus gasseri, L. casei, L. rhamnosus) during 12 weeks improves the the fecal microbiota composition and promotes reduction of plasma/serum levels of acute phase proteins, cytokines, metabolic and anthropometric parameters in individuals with type 2 diabetes mellitus.
Sotalol is an antiarrhythmic medication with proven effects for the suppression and prevention of supraventricular and ventricular arrhythmias. Due to its potential proarrhythmic effect, its introduction should be cautious, and several guidelines recommend starting the medication in hospital settings. However, patients at low risk for a proarrhythmic effect start the medication in outpatient units, despite the lack of clinical studies in the literature that demonstrate the safety of introducing the medication outside the hospital environment. This research project aims to assess the safety introduction of sotalol in an outpatient unit basis. Our hypothesis is that outpatient introduction of sotalol is safe for low-risk patients and an electrocardiographic analysis after 2 hours of the first dose of medication is a predictor of electrocardiographic changes found after 72 hours. In this research, serial electrocardiographic analysis with measurements of the QT corrected intervals and its dispersion, as well as clinical and laboratory parameters will be performed in 110 patients.
Background: Non-invasive ventilation (NIV) reduces respiratory load and demands on peripheral muscles. Methods: This study aims to evaluate the acute effects of bi-level NIV on peripheral muscle function during isokinetic exercise and aerobic performance in chronic obstructive pulmonary disease (COPD) patients. This is a pilot crossover study performed with a non-probabilistic sample of 14 moderate to very severe COPD patients. Procedures carried out in two days. Dyspnea, quality of life, lung function, respiratory muscle strength, functional capacity (6-minute walk test - 6MWT), and isokinetic assessment of the quadriceps were assessed. Blood samples (lactate, lactate dehydrogenase, and creatine kinase concentration) were also collected. Right after, NIV was performed for 30 minutes (bi-level or placebo, according to randomization) followed by new blood sample collection, 6MWT, and isokinetic dynamometer tests. Before and after evaluations, the subjective perception of dyspnea and fatigue in the lower limbs was quantified. After a wash-out period of seven days, participants returned, and all assessments were performed again.
This is a Phase IIIb, multinational, multicenter, randomized, open-label study to evaluate patient preference of the fixed-dose combination of pertuzumab and trastuzumab for subcutaneous use (PH FDC SC) administration in the home setting compared with the hospital setting during the cross-over period of adjuvant treatment in participants with early or locally advanced/inflammatory human epidermal growth factor receptor 2-positive (HER2+) breast cancer.
The aging process is followed by metabolic and body composition changes, increasing the risk of obesity and sarcopenia. The coexistence of these conditions acts synergistically on each other and is known as sarcopenic obesity. Beige adipose tissue is a tissue type that emerges from subcutaneous white adipose tissue (WAT), altering its phenotype to resemble the thermogenic functions of brown adipose tissue (BAT) in response to beta-adrenergic stimuli. Some in vitro and animal studies suggest that taurine supplementation and physical exercise are effective interventions in stimulating the aforementioned tissue, promoting what is known as WAT darkening, improving energy metabolism and showing benefits on the maintenance of muscle mass via stimulation of the coactivating protein PGC1α. These investigations are scarce in humans and could help health professionals in the adjuvant treatment of sarcopenic obesity. Therefore, the aim of the present study is to analyze the effects of taurine supplementation associated or not with physical exercise on the darkening of the WAT in sarcopenic obese elderly women.
Randomized clinical trial to evaluate the effect of vascular photobiomodulation on sleep quality, relaxation and stress when compared to placebo.
This is a multicenter, randomized, double-blind, placebo-controlled, study comparing the efficacy and safety of intravenous (IV) efzofitimod 3 mg/kg and 5 mg/kg versus placebo after 48 weeks of treatment. This study will enroll adults with histologically confirmed pulmonary sarcoidosis receiving stable treatment with oral corticosteroid (OCS), with or without immunosuppressant therapy.
Insomnia is defined as some difficulty in sleep onset, consolidation, duration, or quality, despite appropriate opportunities for getting sleep. In the last decade, there is growing evidence associating insomnia and high blood pressure, (HBP), coronary disease, heart failure, atrial fibrillation, as well as with an increased mortality rate. Despite the previously mentioned advances, the real impact of insomnia on HBP is unknown. It is unclear whether the diagnosis and pharmacologic treatment of insomnia will have an impact on 24-h BP. The aim of this study is to outline the prevalence of insomnia in patients with HBP followed in the ambulatories from the Hypertension Units at InCor and Hospital das Clínicas. The main hypothesis is that the prevalence of insomnia is high and most patients remain undiagnosed and consequently untreated. For this phase, up to 1,500 patients with HBP will be selected. Besides the medical records with demographic and anthropometric data, personal and familiar background, as well as regular medication, all patients will perform three systematic and standardized blood pressure checks on electric monitors.
Changes in salivary parameters, such as decreased flow, changes in pH and composition, can lead to changes in oral health. Saliva is responsible for the homeostasis of the oral cavity and is therefore directly related to the occurrence of caries, periodontitis, fungal and bacterial infections. These situations compromise the quality of life of the population and for this reason prevention and treatment strategies need to be studied and developed. Photobiomodulation is an alternative that has been increasingly practiced by health professionals. It consists of the application of light to a biological system that is capable of inducing a photochemical process, mainly in the mitochondria, thus stimulating the production of energy in the form of adenosine triphosphate (ATP), which can increase cellular metabolism and produce effects. as analgesia and tissue regeneration. In dentistry, studies using photobiomodulation have shown promise in improving some salivary parameters. This study aimed to compare the action of infrared light on salivary flow and pH, using two application techniques: extraoral (G1) and intra and extraoral (G2), with the application interval between the two techniques being 7 days
