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 project aims to evaluate the performance characteristics of rapid tests to differentiate bacterial from non-bacterial infection in febrile adults and children presenting at OPDs (outpatient departments) i.e.("fever triage assays") in three LMICs. The evaluation will include a different commercial biomarker combinations as well as individual biomarkers to assess their individual or combined value in the target population. Markers will be evaluated onsite in ELISA or RDT format, as appropriate. Further, this study aims to contribute to a centralized biobank of well-characterized specimens for use by IVD companies and academic institutions for the development and evaluation of emerging assays.
Introduction. Despite the advantages associated with the use of remifentanil during total intravenous anesthesia (TIVA), it has been observed a frequent difficulty in the control of postoperative pain due to the risk of developing hyperalgesia and acute tolerance associated with the administration of this opioid. There is evidence that NMDA receptors are involved in the development of these changes. Methadone is an opioid that exhibits analgesic potency similar to that of morphine but has NMDA antagonist activity and longer duration of action as additional features. The objective of the study was to evaluate the quality of recovery (QoR40) of patients undergoing TIVA for laparoscopic cholecystectomy and who received morphine or methadone to control postoperative pain. Methods. Patients aged 18 to 65 years, physical status ASA I and II, submitted to total venous anesthesia (propofol and remifentanil) for laparoscopic cholecystectomy and eligible to participate in this prospective and randomized clinical study will be evaluated. After induction of anesthesia, patients will receive a solution containing 0.1 mg.kg-1 morphine (MF group) or 0.1 mg.kg-1 methadone (MT group). Data on the presence of pain, nausea, vomiting, tremor, drowsiness, presence of SpO2 <92%, even with O2 face mask (5 L.min-1) and length of stay will be recorded at PACU. The pain will be evaluated every 15 minutes on a verbal numerical scale (ENV) from 0 to 10. E.v. morphine 0.1 mg.kg-1 (MF group) or methadone 0.1 mg.kg-1 (MT group) will be administered every 15 minutes to obtain the score below 3. After discharge from the PACU, all patients will receive intravenous ketoprofen every 12 hours and dipyrone every 6 hours. For cases where the patient considers the analgesic regimen insufficient, tramadol (100 mg) will be administered intravenously at 8-hour intervals. The consumption of analgesics, the intensity of pain, the occurrence of nausea, vomiting and other complications in the ward will be recorded. The application of the questionnaire (QoR40) will be performed in the ward the morning after the surgery by a medical student.
Contextualization: Exercise is a common triggers of bronchospasm in patients with asthma and healthy subjects. To prevent these symptoms frequently they have to use Short-Acting Beta2-Agonists. However, the cardiovascular effects of salbutamol during and after exercise remain poorly known. Objective: To evaluate the effect of salbutamol on heart rate and blood pressure during exercise in patients with moderate or severe asthma and healthy individuals. Methods: A randomized, double-blind, crossover study will be conducted which 13 individuals with moderate or severe persistent asthma and 13 healthy individuals aged between 20 to 59 years. Patients will perform a maximal effort test on 2 nonconsecutive days, with either 400mcg Salbutamol or 4 placebo puffs. The order of use of placebo or salbutamol will be drawn. During the protocol, heart rate, blood pressure, perception of exertion and peak expiratory flow will be monitored.
This is an adaptative study where each participant's rocuronium dose will depend on the previous patient's response, being higher if it was not enough and lower if it was more than enough.
Evaluate the effects of HIT on the cardiorespiratory performance and substrate oxidation of insulin-resistant and insulin-sensitive obese adolescents.
The research protocol is a Randomized Clinical Trial that has the effectiveness of a given respiratory muscle training protocol over the indicative variables: Pulmonary function; Markers of oxidative stress and inflammation, endothelial markers and Quality of life in patients with chronic kidney disease undergoing hemodialysis. According to the Investigators, this topic was proposed since it is known that several pulmonary complications occur as a consequence of chronic kidney disease due to uremic myopathy. Therefore, the hypothesis is that the application of a respiratory muscle training protocol will contribute positively pulmonary functionality and a decrease in oxidative stress and inflammation in chronic kidney patients, consequently, will bring improvement in the quality of life for these patients. The Patients will be divided into two groups: control group - No intervention of the Muscular Training (CG) And Intervention Group (GI). The intervention protocol will be composed of respiratory muscle training And lasts for two (2) months, with three (3) visits per week. It will be carried out through Threshold PeP appliance. The twelve (12) first training sessions will have a total duration of 30 minutes 15 minutes with inspiratory load of 20 cmH2O and 15 minutes with expiratory load of 20 CmH 2 O; and the others (12) twelve sessions will last 40 minutes each, with 20 minutes with an inspiratory load of 20 CmH2O and 20 minutes with expiratory load of 20 cmH2O. The variables evaluated will be: muscular strength Respiratory (maximum inspiratory pressure and maximum expiratory pressure - Pimáx and Pemáx); Lung function (Slow Vital Capacity - CVL, forced expiratory volume in the first minute - VEF1, Vital Capacity Forced - CVF and Maximum Voluntary Ventilation - VVM); Serum levels of oxidative stress markers, endothelial markers and endothelin.
This prospective nonrandomized multicenter phase I study, will evaluate the feasibility of performing uterine transposition before chemoradiation for rectal cancer and uterine reimplantation after the treatment.
The plantar fasciitis (PF), most frequent injury of the musculoskeletal system, is the main cause of heel pain and functional disability. The mechanical stress, stretching of plantar fascia consequently the overload on the feet, is a major intrinsic causes the onset of FP, especially when exposed to repetitive activities, such as walking. Another extrinsic etiologic factor of great influence is inadequate shoes that can lead to a deterioration and progression of the disease. One of the great difficulties of their conservative treatment is long rehabilitation period, lasting on average 10 to 18 months. Among them, the insoles stand out as one of the effective mechanical treatments to improve the immediate pain symptoms, in the short term. Other literary evidence, not specific to FP, has shown the benefits, the short and long term, a flexible footwear promotes more flexible feet and overload reduction. Objective: Verify therapeutic effect in the long term, a flexible footwear and low cost and orthopedic insole on the clinical aspect, functional and biomechanics of the gait of women with acute FP and chronic with presence of heel spur. It will be conducted a randomized controlled trial with blinded evaluator, in which 79 women with plantar fasciitis will be randomized and allocated to the intervention group with minimalist flexible footwear (MFG, acute n=12 and chronic=15) or the intervention group with orthopedic insole (COIG, acute n=14 and chronic n=14) or control group (CG, n=24). The intervention will have duration six months, six hours a day, seven days a week (42 hours/week). For all groups will be allowed to use pain medication support (paracetamol 500 mg) with a maximum dose of two grams daily. The primary outcome will be the symptom of pain verified by visual analogue scale (VAS), the inability to areas of the feet by the total score of the FFI (Foot Function Index), health feet by FHSQ-Br questionnaire (Foot Health Questionnaire Status) and the distance traveled by the six-minute walk test (6MWT). The secondary: plantar pressure and ground reaction force during gait, paracetamol consumption and the joint angles of the lower limbs. The effects of time (Start, 3 and 6 months), group (GIC and GIP CG) and interaction (time and group) are calculated by means of ANOVA case-wise two factors. A 5% alpha to significant differences and Cohen coefficient for describing the size effect of the intervention is assumed.
This randomized, controlled clinical trial, triple-blind, split-mouth type was conducted aiming to assess the absolute risk of sensitivity with and without sonic activation of a desensitizing gel previously to the in-office bleaching in adults.
The study proposes to assess the effect of multiple applications of antimicrobial Photodynamic Therapy (aPDT) as an adjunct to non-surgical periodontal treatment (nsPT) in smokers without use of antibiotics. Twenty smokers with a clinical diagnosis of chronic periodontitis will be treated in a split-mouth design study to either aPDT associated with scaling and root planing (SRP) or SRP only. aPDT will be performed by using a laser light source with 690 nm wavelength associated with a phenothiazine photosensitizer. The applications will occur in four episodes (at days 0, 2, 7 and 14). All patients will be monitored for 90 days. Plaque index, probing depth, clinical attachment level and bleeding on probing will be performed at baseline (pre-intervention period) and 30 and 90 days after the (nsPT). Subgingival plaque samples will be collected (at baseline and 30 and 90 days after the nsPT) and the counts of 40 subgingival species will be determined using DNA-DNA checkerboard hybridization. Gingival crevicular fluid samples will be collected (at Day 0, 14, 30 and 90 after the nsPT) and the levels of Interleukin 1 beta, Interleukin 10 and Tumor Necrosis Factor alpha (Luminex) will be evaluated. Salivary cotinine levels will also be evaluated at baseline. Data obtained will be statistically analyzed.
