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.
Hepatic venous pressure gradient (HVPG) is an invasive test and requires technical skills of the operator and specialized instruments. HVPG measurement and anesthesia can cause stress responses in the body, which in turn lead to inflammatory response and immune function suppression. Thus, the perioperative care for patients undergoing HVPG measurement is crucial. This research trial studies comprehensive patient and medical worker questionnaires in predicting complications in patients with cirrhosis undergoing HVPG measurement. Comprehensive patient and medical worker questionnaires may help identify complications, such as the need for assistance in taking medication, decreased mobility and released tension that may improve outcomes.
Aging has been associated with reduced bioavailability of nitric oxide(NO) and endotelial dysfunction.Curcumin, a phenolic compound present in the rhizomes of turmeric, possesses cardiovascular protective, anti-inflammatory and antioxidante properties. The present study is evaluating the effects of ingestion of 10 g of curcumin supplementation (CUR) on microvascular responsiveness and tissue oxygen saturation in the elderly with cardiometabolic risks.Twenty eight older individuals have been submitted to 10 g of curcumin suplementation (CUR) or placebo (PLA) (sucralose). Microvascular responsiveness and tissue oxygen saturation have been measured 120 minutes after interventions.
Sjogren's Syndrome (SS) is an autoimune disease of unknown etiology characterized by lymphocytic infiltration of the exocrine glands and other organs. patients usually presents with xerophthalmia, xerostomia, fatigue and other symptoms. Fatigue has often been reported as the biggest problem and the most difficult symptom patients have to deal with. Fatigue management in pSS is difficult. However, in other diseases such as Parkinson disease, post-polio syndrome and multiple sclerosis the use of Transcranial Direct Current Stimulation (tDCS) has recently been studied and has shown effectiveness. The overarching objective of this study is to examine the effect of a tDCS protocol in patients with pSS.
The International Cohort Study of Children Born to Women Infected with Zika Virus (ZIKV) During Pregnancy study is a prospective, observational, international cohort study of children previously enrolled in the ZIP study or other ZIP 2.0 Protocol Team approved ZIKV-cohort study that will continue the longitudinal follow-up of children born with documented confirmed or presumptive in-utero ZIKV exposure ("ZIKV-exposed" cohort) and children born without documented confirmed or presumptive in-utero ZIKV exposure, matched by site and birth sex ("ZIKV-unexposed" cohort). Follow-up evaluations and assessments will allow for the determination and comparison of long-term neurodevelopmental outcomes among in utero ZIKV-exposed and ZIKV-unexposed children. Each participant will be followed for about 2 years, beginning at approximately 18 months through 42 months of age.
he increasing prevalence of obesity in developed countries has also reached Brazil in the last two decades. Conventional treatments are not efficient to sustained weight loss and in some cases, weight reduction in individuals refractory to these methods. Bariatric surgery has been considered as the most efficient long-term treatment. However, numerous studies have reported weight regain in approximately 20% of patients, from the second year of surgery. The objective of this study is to analyze the changes in resting metabolic rate and body composition before, 6 and 36 months after weight loss and its relation to late weight regain. 48 adults of both sexes, above 18 years, will undergo bypass performed the ambulatory of the Bariatric and Metabolic Surgery Unit of the Department of Gastroenterology of HCFMUSP. Patients over 60 years, undergoing revision surgery and other surgical techniques will be excluded. The body weight (kg) will be measured by In Body 230. BMI (kg/m2) shall be determined by dividing body weight (kg) by height (m) squared. Excess weight (kg): difference in preoperative weight versus ideal weight considered for weight for BMI 25kg/m2. Weight loss (kg): pre-surgery weight difference in relation to the lowest weight reached after 18 months. Percentage of excess of weight loss is difference of weight loss in relation to overweight, used as an indicator of success of surgery. Fat mass (%, kg) and fat-free mass (%, kg) will be obtained by electrical bioimpedance 230, 2.0. For resting metabolic rate, the values of VO2 and VCO2 will be collected by indirect calorimetry using Ultima CPX metabolic analyzer. The daily energy expenditure (kcal/day) will be calculated by the Weir equation. keywords: obesity, resting metabolic rate, body composition analysis, bariatric surgery.
The present project aims to investigate if the empagliflozin has an antiarrhythmic action. Analyzing the T-wave heterogeneity index, a new electrocardiographic risk marker associated with the prediction of cardiovascular risk, in diabetic patients and coronary artery disease, the investigators will verify if empagliflozin is associated with a reduction in electrical instability.
To describe real-world demographic and clinical characteristics, treatment characteristics, and clinical outcomes among patients in Latin America who were treated with first-line sunitinib for metastatic renal cell carcinoma and switched from the 4/2 to 2/1 administration schedule
This study aims was evaluated the effect of L-arginine on microcirculation, vasoreactivity / endothelial function and vascular smooth muscle of young and old women with Sarcopenia or Type 2 Diabetes Mellitus measured by Nailfold videocapillaroscopy and venous occlusion plethysmography before and after 14 days of consumption 5g oral L-arginine supplementation.
A randomized multi-arm study evaluating the efficacy and safety of nivolumab versus placebo in combination with neoadjuvant (pre-surgery) chemotherapy and adjuvant (post-surgery) endocrine therapy in participants with high-risk, estrogen receptor-positive, human epidermal growth factor receptor 2-negative (ER+, HER2-) early stage breast cancer.
Parkinson's disease (PD) is the second most common neurodegenerative disease in the world, considering the central nervous system disorders that affect movement. In addition to motor impairment, the literature reinforces changes in ventilatory parameters, such as restrictive lung dysfunction, obstructive airway disease, and upper airway obstruction. Pulmonary disorders are more evident in patients in later and advanced stages of PD, and are responsible for most of the morbimortalities resulting from the disease. Objectives: To evaluate the effects of a protocol of diaphragmatic awareness, in association with the global exercises, on the pulmonary function of individuals with Parkinson's disease. Methods: This is an experimental, uncontrolled clinical trial. Participants are patients with Parkinson's disease referred for care at the UEAFTO / CER-II UEPA neurofunctional outpatient clinic whose records will be consulted for the collection of epidemiological data and postural assessment of cognitive functions through protocol Montreal Cognitive Assessment (Brazilian experimental version) and classification by modified Hoehn and Yahr scale. Those who meet the inclusion criteria will be evaluated through the evaluation form, Pulmonary Functional Status and Dyspnea Questionnair protocol, submitted to Pulmonary Function Test and respiratory muscle strength assessment by Spirometry and Manovacuometry, respectively. They will be submitted to an intervention protocol prepared by the physiotherapy team of UEPA's Elderly Care Center for 20 sessions lasting 60 minutes twice a week, consisting of global exercises and diaphragmatic awareness, being re-evaluated in the 10th and 20th sessions. The protocol used will be registered in the Clinical Trials database. All participants will sign a Free and Informed Consent Form and the research will be submitted to analysis by the Human Research Ethics Committee of the University of the State of Pará (UEPA). The data collected will be tabulated in a Microsoft Excel 2016® worksheet for further statistical analysis using BioEstat® 5.3 software. Expected results: obtain an improvement in the variables related to pulmonary function in the experimental group after the application of the intervention protocol and in relation to the control group.
