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.
To prevent the development of ICUAW, both early mobilization and neuromuscular electrical stimulation (NMES) have been shown to prevent muscle atrophy in critically ill patients by preserving muscle mass. Furthermore, it is of great value that muscle assessment using kinesiological ultrasound becomes routine to monitor this patient's profile with regard to strength, muscle quality and muscle mass. Our objective is to evaluate the muscular changes promoted by NMES in patients under mechanical ventilation. This is a randomized clinical trial study, which will perform NMES sessions for at least 10 days in mechanically ventilated patients. They will also undergo ultrasound assessments of the quadriceps. Patients will be divided into a control group and an NMES group. In addition, general information recorded in the medical record will be collected, such as basic characteristics, laboratory tests and general assessments.
The EPIC-15 trial will evaluate the safety, pharmacokinetics, acceptability, and efficacy of pediatric ivermectin (CHILD-IVITAB) in scabies infected children weighing 5 to less than 15 kg. This trial will support future efforts to expand the indication of ivermectin treatment to infants weighing 5 to less than 15 kg to treat numerous NTDs, allowing this young age group equitable access to the numerous benefits of pediatric ivermectin therapy
The innate immune response of children with acute viral bronchiolitis (AVB) caused by respiratory syncytial virus (RSV) in the acute phase and in the resolution phase, is marked by variations in inflammatory and anti-inflammatory mediators, where in the acute phase there is recruitment and activation of multiple cells of the immune system, with consequent increase in the expression of pro-inflammatory mediators. Evidence indicates that there is a considerable increase in tumor necrosis factor-alpha (TNF) , interleukine 6 (IL6), interleukine 1-beta, interleukine 8 (IL8) interleukine 10 (IL10), exposing to IL6, IL8 and IL-10 positively correlated with AVB severity. There are already reports that the transcutaneous application of photobiomodulation (PBM) reaches the lungs, producing positive responses in respiratory pathologies, both acute and chronic . Thus, PBM caused by the use of low-level laser may be a favorable resource to be used in the area of respiratory physiotherapy, specifically in neonatology and pediatrics, since there are studies in both experimental and human models that prove its action on lung cells, acting to reduce airway edema, reduce neutrophil migration to lung tissue and synthesize pro-inflammatory cytokines TNFalpha, IL6 and IL-10. In addition, it is a portable, practical, quick application, with minimal contraindications and possibly better tolerated by the neonatal and pediatric population.
The aim of this study is to evaluate the effects of Brazil nut supplementation on inflammation, oxidative stress and intestinal microbiota in patients with chronic kidney disease undergoing conservative treatment.
The increase prevalence of chronic kidney disease (CKD) over the years represent a significant public health problem. The role of inflammation and oxidative stress in the pathophysiology of CKD, as well as progression and comorbidities, is already well consolidated. The gut microbiota composition imbalance may also be a risk factor contributing to the increased conditions mentioned above, and to uremic toxins release and endotoxemia. The literature has indicated the use of bioactive compounds as a nonpharmacological treatment strategies for the management of non-communicable diseases (NCDs), such as CKD and its complications. In this context, jaboticaba (Plinia Cauliflora) emerges as a potential therapeutic approach as it is a source of phenolic compounds, such as anthocyanins, flavonols, ellagitannins, and phenolic acids. Such phenolic compounds may have beneficial effects in patients with CKD, such as anti-inflammatory, antioxidant, modulation of the intestinal microbiota, hypotensive and hypoglycemic effects. These combined effects can help manage risk factors and CKD itself, and associated complications. Therefore, this research project aims to add scientific knowledge, providing a non-pharmacological therapeutic approach to be implemented in clinical practice and in the care of patients with CKD, with the aim of modulating inflammation, oxidative stress, microbiota composition, and improving the quality of life of these patients. Therefore, this study aims to evaluate the effects of jaboticaba (Plinia Cauliflora) supplementation on complications associated with CKD.
The Early Oral Aging Syndrome (EOAS) is a broad concept concerning changes in oral health caused by systemic diseases of different origins, which are related to the current lifestyle in the pediatric population. Enamel defects associated with intrinsic and extrinsic factors promote the acceleration of dental structure loss in an early manner, causing impairment of function, aesthetics, and quality of life. In this context, this study aims to identify the prevalence of early childhood tooth wear and its severity using the Early Childhood Oral Aging Syndrome (EOAS) index as a diagnostic and epidemiological survey instrument, considering current alterations found in the pediatric population and verifying possible factors associated with each severity level. Participants aged 3 to 6 years old, enrolled in the pediatric dentistry clinic of the University Nove de Julho, will be selected. Children with imperfect amelogenesis and dentinogenesis, genetic syndromes, and undergoing orthodontic treatment will be excluded from the research. A questionnaire on general health, sleep quality, nutrition, hygiene habits, and parafunctional habits will be administered. Subsequently, a clinical examination will be conducted using the new Early Childhood Oral Aging Syndrome (EOAS) index with scores ranging from 0 to 3 to assess dental wear and dental management, and scores I to III that should be used concomitantly in cases of enamel defects presence, in addition to measuring the Vertical Dimension of Occlusion (VDO). EOAS scores will be computed and statistically analyzed for deciduous dentition with a significance level of P<0.05.
Background: Tai Chi Chuan, a Chinese martial art style, is a mind-body modality that has shown positive impacts on health markers in various populations, particularly older adults. This study aims to investigate the effects of a 12-week program of Tai Chi Chuan exercises based on the Yang 16-movement form and walking on older adults' physical and mental markers. Methods: This study is a randomized, single-blinded, two-arm, parallel, superiority trial. Forty older adults between 60 and 75 years old who are not engaged in any systematic strength and aerobic training program will be recruited. Candidates with language and cognitive problems, a history of cardiovascular diseases (except controlled hypertension), osteoarticular limitations and fractures, severe injuries, and prosthetic placement in the last six months will be excluded. Participants will be randomly allocated on a 1:1 ratio to a 12-week intervention with Tai Chi Chuan and walking two times per week, or an active-control group with walking two times per week. Physical measures will be muscle strength (i.e., knee extensors maximum strength and lower limbs functional performance -primary outcomes-, dynamic knee extensors endurance, handgrip strength, back-leg-chest strength), functional capacity, static balance, muscle thickness and muscle quality of quadriceps. Mental measures will be quality of life, sleep quality, cognitive function, and depressive and anxiety symptoms. Outcomes will be measured before and after 12 weeks of intervention. The analysis plan will use an intention-to-treat approach and protocol criteria. Discussion: The conceptual hypothesis is that the intervention training program with Tai Chi Chuan and walking will lead to greater improvements in both physical and mental parameters due to its multi-component character compared to the walking active-control group.
Premature, non-physiological tooth wear in childhood has numerous repercussions for oral health. This is a growing problem with multifactorial causes and associated with the current lifestyle. The aim of the present study was the development and determination of content validity of the Childhood Early Oral Aging Syndrome (CEOAS) index for the primary dentition as a diagnostic and epidemiological survey tool considering the current changes found in this population.
Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), a major global public health concern, is commonly associated with obesity, diabetes, and dyslipidemia. MASLD is currently the most common cause of chronic liver disease affecting about 80% of people with obesity, ranging from simple fat deposits in the liver to Metabolic Dysfunction-Associated Steatohepatitis (MASH), cellular injury, advanced fibrosis, cirrhosis, or hepatocellular carcinoma. Patients with MASH are also at risk for cardiovascular disease and mortality. There is no universally approved medication for MASH. Weight loss remains the cornerstone of MASH treatment. Patients meeting the inclusion and exclusion criteria and who give informed consent will be enrolled in the trial and undergo the baseline liver biopsy (if none available). Approximately 120 patients with MASH and liver fibrosis (F1-F4 in baseline liver biopsy) will be randomized in a 1:1 ratio to metabolic surgery or medical treatment (incretin-based therapies ± other medical therapies for MASH) and followed for 2 years at which time a repeat liver biopsy will be performed for the assessment of the primary end point.
This project will be conducted in 2 hospitals in Brazil to assess the requirements for four essential amino acids in TPN fed neonates. Using the Carbon Oxidation method (indicator amino oxidation and direct amino acid oxidation method), the investigators will determine the requirement of each of the 4 amino acids. The investigators will determine the requirement for Isoleucine, Leucine, Valine and Tryptophan. The investigators will recruit 18- 20 babies per amino acid study. Breath and urine samples will be collected to determine the oxidation of the indicator amino acid. The response of the indicator amino acid to changes in intake of the test amino acid (isoleucine, leucine, valine and tryptophan) will be analyzed by bi-phase linear mixed effect model to determine the breakpoint or mean requirement for each amino acid. It is hypothesized that the requirement for isoleucine, leucine, valine and tryptophan will be at least 50% lower than what is currently available in commercial solutions used for TPN feeding of neonates.
