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.
In this study the investigators will submit patients with treatment resistant depression to deep anesthesia with isoflurane to get 15 minutes of cortical burst suppression on electroencephalogram, once a week for six weeks. The follow up will be for 6 months. The aim is to evaluate the change in depression severity during the entire period.
Obstructive sleep apnea syndrome (OSAS) is defined as a total cessation of upper airway flow for at least 10 seconds. OSAS is considered under diagnosed and it is assessed by a full-night sleep polysomnography. Continuous positive airway pressure (CPAP) is considered the first line treatment to OSAS, however physical exercise has emerged as an adjunct and/or alternative strategy to CPAP in OSAS patients.
In this study we wondered whether patients with different phenotypes of Parkinson's disease respond differently to the protocol of repetitive transcranial magnetic stimulation (rTMS) associated with physical therapy. Furthermore, the study aims to compare the effects of rTMS protocols (high and low frequency) associated with physical therapy in PD patients with different phenotypes regarding to motor performance; bradykinesia; functional mobility; balance; quality of life; perception of improvement.
The balanced anesthesia process contains three main parts: the control of hypnosis, analgesia, and neuromuscular blockade. For the induction phase, the anesthesiologist performs protocols based on prior planning specific to each patient and usually performs these controls by monitoring the classic vital signs and other clinical signs for the maintenance phase. In a way, this professional is the controller in a control system that acts on the plant (the patient) through the infusion of hypnotic drugs, analgesics and neuromuscular blockers. In addition, the anesthesiologist estimates the state of consciousness, the level of analgesia and the level of neuromuscular blockage through other indirect measures, as well as a state observer. There are different techniques for direct monitoring of these three anesthesia variables (DoA, NMB and NoL), such as BIS and Narcotrend, but all have some disadvantages, especially when the anesthesia process combines different drugs. This work proposes a new way of evaluating DoA, NMB and NoL using data fusion techniques to combine classical clinical signs with advanced EEG monitoring techniques to provide a decision support system for the anesthesiologist.
Introduction: Quadriceps weakness was previously associated with functional impairment of osteoarthritis (OA). Evidence also suggests that muscle strength may prevent the progression of existing OA. It is estimated that the decline in muscle mass between 40 and 80 years is between 30% and 50%, with reported losses in functional capacity reaching 3% each year beyond the age of 60 years. Therefore, procedures capable of increasing the effects of exercise on muscle strength and function may be beneficial for elderly patients with knee OA. The results of our studies have shown that with each year of life the patient loses strength gain capacity. Objective: To evaluate if a multiprofessional educational program associated with BCAA and creatine supplementation improves the quality of life, function, pain and body composition of patients with OA and age greater than or equal to 70 years. METHODS: 34 patients with knee OA and age greater than or equal to 70 years will undergo an educational and physical training program lasting 20 weeks. Half of the patients will receive creatine (control) and the others will receive creatine and BCAA (study). Patients will be evaluated through functional tests (sit-up and 30-second tests and time up and go), standardized questionnaires (WOMAC and Lequesne), quality of life scales (Euroqol-EQ-5D-5L), pain (through VAS), body composition and bone density (through densitometry), and level of physical activity. All of the above parameters will be assessed at the beginning of the study and 6 and 12 months later. All project costs will be reported and a cost-effectiveness and cost-utility analysis will be performed. All project costs will be reported and a cost-effectiveness and cost-utility analysis will be performed.
Single arm phase II trial designed to assess the efficacy of durvalumab treatment in terms of 6-month progression-free survival. We will include 22 patients who will receive 1500 mg durvalumab (MEDI4736) via IV infusion Q4W <<for up to a maximum of 12 months (up to 13 doses/cycles) with the last administration on week 48>> or <<until confirmed disease progression>> unless there is unacceptable toxicity, withdrawal of consent, or another discontinuation criterion is met. If a patient's weight falls to 30 kg or below for 1 week or longer ( ≥ 7 days) durvalumab will be permanently discontinued.
This intervention, called MMP®, is a procedure whereby drugs are injected through tattoo machines.
Objective: To investigate the effects of EMG biofeedback training on the pattern of scapular muscle activation and kinematics in subjects with subacromial pain syndrome. Methods: This is a randomized controlled trial, which will be composed of 40 volunteers of both genders, aged between 30 and 60 years. All volunteers will undergo pre-assessment (IA): pain sensation, pain and function, shoulder range of motion, muscle strength, electromyographic activity and kinematics of the shoulder complex. After the initial evaluation, the volunteers will be randomly divided into two groups for the intervention: exercises group (GE - conventional exercises with elastic band) and Biofeedback group (BG - Biofeedback training). The intervention protocol will last eight weeks. After four weeks, the second assessment (SA), similar to IA, will be performed and the global change perception questionnaire will be added. At the end of the intervention protocol, the third evaluation (TA), similar to SA, will be performed. A follow-up will be performed 4 weeks after the end of the intervention protocol, with the assessment being equal to TA. Statistical Analysis will be performed through Statistical Package for Social Sciences (SPSS) software version 20.0 for Windows, following the principles of intention-to-treat analysis. The descriptive analysis will use the mean as a measure of central tendency and the standard deviation as a measure of dispersion. A mixed model ANOVA will be performed for intra and intergroup comparisons.
This study evaluates the use of photobiomodulation in the treatment of patients with Parkinson's disease. Half of participants will receive treatment with low level laser therapy and exercises in combination, while the other half will receive a placebo laser combined with exercises.
Blood pressure control is crucial for individuals' wellbeing. However, many daily aspects such as diet could impair blood pressure control. In addition, many people living under different conditions in different countries are affected by some kind of gum disease. These people experience gingival bleeding, bad breath, teeth mobility and pain. Throughout gum disease development the number of oral germs in the mouth increases including their levels in tongue surface. Oral bacterial are able to convert nitrate widely found in food in nitrite which influences blood pressure. Frequently treatment of gum diseases general combines manual instrumentation with mouthwashes. However, it has been suggested that reduction of oral bacteria by mouthwashes, especially chlorhexidine, is accompanied by decreased conversion of nitrate to nitrite and that this minor nitrite availability would increase blood pressure. Therefore, this is a point to be clarified for patients, physicians and dentists. This study will investigate the relation between treatment with mouthwashes and blood pressure of patients with destructive gum disease based on nitrite levels in saliva, bacterial levels in tongue and values of arterial blood pressure which will be monitored over 6 months. In addition, usual clinical parameters and alteration of oral cells' DNA will be also monitored overtime. Patients will be treated under local anesthesia and manual instrumentation within 24 hours. They will receive oral care products too. There will be 3 treatment groups (manual instrumentation + chlorhexidine mouthwash [2 times a day for 3 weeks], manual instrumentation + placebo mouthwash [2 times a day for 3 weeks] and manual instrumentation + no mouthwash) and 2 dental appointments before treatment. After treatment, patients will be examined at 7, 14, 21, 90 and 180 days. Saliva, plaque and cell sampling will be fast and by no invasive methods.
