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 aims to evaluate the acute and subacute effects of an inhaled N, N-Dimethyltryptamine in healthy individuals.
Literature establishes that warming with a heated blanket before and during the operation is effective in the prevention of perioperative hypothermia, both in general anesthesia as well as spinal anesthesia. However, the trials have still not presented us with objective protocols to standardize this routine in the surgical centers. The study aims to assess the adoption and reproduction of the implementation of the warning device by the nursing team immediately after the patient's entrance in the operating room, even before the entrance of the anesthesiologist.
INTRODUCTION: There are several ways to assess muscle strength: not only subjective ways, but also high standard equipment, such as isokinetic dynamometers. These, however, are expensive, and require extensive training. Over the years, manual dynamometers were produced, portable equipment that simplify its use. Among them, a national equipment was developed, but its reliability and validation are yet to be confirmed, compared to equipment already used, such as the Lafayette®. OBJECTIVE: Assess the reliability of a new manual dynamometer - Medeor® device (SP Tech model) -, in relation to the gold standard, Lafayette® device (model 01165), already validated, in the evaluation of muscle strength of the knee and hip groups. METHODS: A total of 26 recruits of both sexes were selected. Muscle strength was measured by Lafayette® and Medeor® dynamometers in the following groups: knee flexors and extensors; flexors, extensors, abductors, adductors, hips internal and external rotators. Each data was collected 3 times, and then the average was calculated.
This research was characterized as a cross-sectional observational study, following the recommendations of the STROBE instrument. Therefore, it was conducted in the Intensive Care Unit of Otávio de Freitas Hospital (HOF) in Recife/PE, with patients over 18 years old who had a clinical diagnosis of COVID-19, using two methods of oxygen therapy (Nasal Oxygen Therapy) and (non-rebreather mask). Consequently, clinical evaluations were performed regarding the disease, severity of COVID-19, perception of respiratory effort, and electromyography of respiratory muscles. 1. Leading Question: How does the recruitment pattern of diaphragmatic and extradiaphragmatic muscles in patients with acute hypoxemia caused by COVID-19 behave when assessed through EMGs, considering the SpO2/FiO2 ratio as the analysis parameter? 2. Leading Question: Is there a relationship between the respiratory work estimated by electromyographic activity of diaphragmatic and extradiaphragmatic muscles in patients with acute hypoxemia due to COVID-19 and the parameters of respiratory frequency and levels of acute hypoxemia measured by the SpO2/FiO2 ratio? The rationale for this study is that the COVID-19 pandemic has caused significant impacts on global public health due to the high volume of respiratory complications in the face of a limited supply of healthcare resources, consequently leading to high mortality. Complications are initially manifested by acute hypoxemia associated with COVID-19 infection, sometimes silent upon visual inspection or using less sensitive methods. This complicates the management of compensatory respiratory work for hypoxemia, even with oxygen therapy support. Respiratory muscle recruitment involves aspects of inspiratory effort and ventilatory mechanics. Recognizing the presence and recruitment pattern of muscles involved in a timely manner can contribute to the clinical management success rate of individuals affected by respiratory dysfunction associated with COVID-19, especially at different levels of acute hypoxemia. Surface electromyography is a non-invasive, low-risk tool compatible with the analysis of respiratory muscle recruitment patterns. However, there are no studies describing this pattern in COVID-19 patients, serving as a basis for personalized therapeutic strategies.
Observational, longitudinal (retrospective cohort), multicenter, national study aiming to evaluate the proportion of women with HR+/HER2- advanced breast cancer treated with ribociclib plus non-steroidal aromatase inhibitors who were alive and without disease progression at 1 year.
Nutritional and metabolic alterations in patients with chronic kidney disease (CKD) such as inflammation, oxidative stress, dyslipidemia, and poor nutritional status which associate with poor clinical outcome can potentially be targeted and ameliorated by interventions using nutritional supplements. The investigators evaluated the effects of 8 weeks of oral supplementation with flaxseed oil and pomegranate dry extract on markers of inflammation, lipid profile and nutritional status of individuals undergoing hemodialysis (HD). The goal of this randomized, placebo-controlled, double-blind clinical trial is to evaluate the effects of 8 weeks of oral supplementation with flaxseed oil and pomegranate dry extract on markers of inflammation, lipid profile and nutritional status of individuals undergoing hemodialysis (HD). Participants will be randomly assigned, in a 1:1 ratio, to supplementation group to receive twice a day 1 capsule of 1.000 mg of flaxseed oil plus 1 capsule of 600mg of pomegranate dry extract; or to placebo group, to receive twice a day 1 capsule of 1.000 mg of sunflower oil plus 1 capsule of 600mg of microcrystalline celulose.
Childhood obesity increases significantly, and determines several complications in childhood and adulthood, and the worldwide prevalence of childhood obesity has shown a rapid increase in recent decades. The severity of obesity-related risk factors is directly linked to body fat topography, and variations in body fat distribution in obese children can be of high value in predicting future health risks, like of cardiovascular disease in adulthood. There is a potential correlation between obesity and sleep disorders, increasing the predisposition to obstructive sleep apnea syndrome, that is a frequent complication, affecting up to 80% of obese children and adolescents. In relation to postural control, and that anthropometric indicators interfere with children's postural balance, already verified by balance assessment using computerized dynamic posturography. Several studies show that physical activity in childhood and adolescence can influence healthy habits in adulthood. Children and youth ages 5 to 17 should accumulate at least 60 minutes of moderate to vigorous-intensity physical activity daily. It is important to emphasize that the COVID-19 has impacted every aspect of healthcare delivery, and therefore Telerehabilitation has been satisfactorily addressed in reabilitation In the exercise recommendations for children, exercise programs performing aerobic and resistance exercises at a high level of intensity, on a frequent basis (3-5 days a week) for 30-80 minutes, seeking intensity of 50-90% of the maximum heart rate (HRmax), can be used and are shown to be efficient for the treatment of obesity. Therefore the High-intensity interval training (HIIT) describes physical exercise that is characterized by brief, intermittent bursts of vigorous activity, interspersed with periods of rest, cab generate favorable metabolic adaptations on sleep and body weight loss. Outcome Measures: Primary Outcome Measures - The effects of high-intensity interval training (HIIT) and high-intensity functional training (HIFT) through Telerehabilitation on body composition and Obstructive sleep apnea (assessed by body mass index and bioimpedanceand polysomnography type 4) Secondary Outcome Measures - Functional performance of children and adolescents (3 minute step test) - Balance (balance assessments with Wii Balance board) Inclusion Criteria: - Age ≥ 6 to 17 years; - Confirmed obesity children by body mass index acorrding to the age
The main purpose of this study is to evaluate the efficacy and safety of LY3473329 in adult participants with elevated Lp(a) at high risk for cardiovascular events.
The overall goal of this feasibility study is to make adaptations to these evidence-based approaches in collaboration with PLWH and health care providers working with this population, and develop, implement, and evaluate the feasibility and scalability of a theory-based, culturally relevant tobacco cessation intervention for PLWH receiving care through the public health system in a southern town in Brazil (Londrina). This proposal will focus on the intervention development, pretesting, and feasibility testing. The primary outcome will be a 7-day point prevalence abstinence (defined as no tobacco use in the past 7 days and verified through measurement of salivary cotinine and exhaled carbon monoxide levels) at 6-month follow-up. We will also conduct detailed treatment fidelity and scalability assessments (acceptability, feasibility, potential reach and adoption, alignment with the strategic context) to inform a full-scale efficacy trial.
