The aim of this study is to evaluate the 18-month clinical performance of a multimode adhesive (Scotchbond Universal Adhesive, 3M ESPE, St Paul, MN, USA) in primary molars after partial carious removal. This randomized clinical trial will include subjects (5-10 year-old children) selected at two university centers (UFSM and FOUSP). The sample will consist of 132 primary molars presenting active cavitated carious lesions (with radiographic involvement of the outer half of the dentin), located on the occlusal and occlusal-proximal surface. The sample will be randomly divided into two groups according to bonding approach: etch-and-rinse or self-etch strategy. The restorations will be clinically followed every 6 months for up to 18 months using the USPHS modified criteria for clinical evaluation. Survival estimates for restoration longevity will be evaluated using the Kaplan-Meier method.

The purpose of this study is to determine the early effects of transcranial direct current stimulation (tDCS) in patients with mild traumatic brain injury and persistent post concussion syndrome(PPCS) with cognitive deficits in long term episodic memory and executive function(inhibitory control).
Introduction: the influence of temporomandibular disorders (TMD) related to postural changes are yet no consensus, but it is believed that the imbalances of a system can influence another. Several techniques have been used to treat TMD and its associated problems, however there is a paucity of studies evaluating the effects of global treatments, such as Pilates, in individuals with TMD literature. Objective: To evaluate changes in the level of pain, the severity of TMD, the EMG activity of masticatory muscles and posture of young women undergoing training in Pilates, as well as correlating postural changes, pain level, severity of TMD and EMG activity of masticatory muscles. A randomized clinical trial with blinded assessors will be held. 40 patients divided randomly into two groups will be assessed, the control group (CG) who receive conventional treatment with occlusal splint and intervention group (IG), which in addition to conventional treatment will undergo Pilates sessions. Both groups will be formed for women aged 18 to 35 years with TMD and pain. The IG will receive treatment with the Pilates Method for 15 weeks with frequency of twice weekly and use occlusal splint as directed by the dentist. The CG will make use of occlusal splint alone. At the beginning and end of the 15 weeks the individuals are evaluated to verify the presence of TMD, TMD severity, pain, EMG evaluation of masticatory muscles and body posture. Data will be analyzed statistically.
Hypertension has high prevalence and poor control rates and is considered one of the major modifiable risk factors for cardiovascular system diseases, and one of the most important public health problems. The imbalance of the autonomic cardiovascular control, which can be considered as a major etiologic factor in the development of essential hypertension is characterized by increased sympathetic activity and reduced parasympathetic activity possible. Cardiovascular disease is the leading cause of death and disability in the world and autonomic imbalance is associated with several pathological conditions, and may be a final common pathway for the increased morbidity and mortality of cardiovascular diseases. In this sense, the heart rate variability (HRV) is a quantitative marker of sympathetic and parasympathetic activity, which can be used to assess disease and mortality as a noninvasive technique. TENS is a noninvasive therapeutic modality, easy to handle, it has no side effects or interactions with medications being used for the relief of pain by sensory stimulation through peripheral nerves and mainly for control and treatment of acute and chronic pain . Research on the effect of TENS on the sympathetic and parasympathetic nervous system activity remain controversial, especially regarding the parameters to use. The aim of this study is to investigate the effects of TENS on the sympathetic and parasympathetic nervous system in patients with hypertension by heart rate variability and blood pressure variability. This is a randomized clinical trial, double blind, where hypertensive patients were randomized to three groups: high-frequency TENS (100 Hz) n = 20, low frequency TENS (4 Hz) n = 20 and n = 20 placebo. Evaluations will be made in a single session. The results will be assessed by a blinded investigator and randomization will be done electronically. It is expected to evaluate how often TENS exerts more influence in the modulation of sympathetic and parasympathetic system.
This randomized, multi-center, active-controlled, open-label, parallel-group study will investigate the efficacy and safety of biomarker-driven maintenance treatment for first-line mCRC. Participants with mCRC are eligible for entry and cannot have received any prior chemotherapy in the metastatic setting. The entire study duration is anticipated to be approximately 7.5 years.
Knee dislocation is a serious injury, usually caused by high-energy trauma. It is classically defined as complete loss of articular congruence between the femur and the tibia, confirmed by radiography. However it is common that the reduction happens spontaneously. For this reason, today the investigators also consider a patient suffered knee dislocation in the presence of multi-ligament injury involving the posterior cruciate ligament, often in association with anterior cruciate ligament, lateral and/or medial ligamentous complex. It is considered a serious injury, because both the strong association with vascular and nerve damage, which can lead to the need for limb amputation, such as the difficulty in obtaining a good functional outcome even after treatment of all ligament injuries. The treatment of these injuries aims to achieve knee stability. Joint mobility is often sacrificed in the postoperative period, with the use of immobilizations such as casts, splints or bracing. Unfavorable clinical outcomes with high rates of stiffness and joint pain are very common in these patients. In attempts to improve these results, rehabilitation protocols with early range of motion can be employed. However, results may remain unsatisfactory, predominantly because of knee instability recurrence. Stannard and Zaffagnini proposed a new model for treatment of acute knee dislocations. In this model, after multi-ligament reconstruction or repair, a knee articulated external fixator is used. Such external fixator allows early and aggressive joint mobility in the sagittal plane only. Flexion and extension are permitted, but rotational movements, translations in the anterior-posterior plane, lateral (varus) and medial (valgus) openings are not allowed. Thus protective stability is ensured for ligament reconstruction procedures. Simultaneously the investigators allow immediate joint mobilization, reducing the risk of arthrofibrosis, joint stiffness and postoperative ligament laxity. There is no consensus regarding the use of hinged external fixator postoperatively in multiple ligament reconstruction procedures for treatment of knee dislocations. The objective of this study is comparing functional outcomes after ligament reconstruction in patients with knee dislocation, with or without the use of hinged external fixator.
