To estimate the effect on carriage, all year 10, 11, and 12 students will be offered 4CMenB vaccination in South Australia through schools over the study period with 50% of the students enrolled receiving the vaccine in 2017 and 50% in 2018. In year 10 and 11 students, posterior pharyngeal swabs will be obtained at baseline and 12 months post baseline to estimate the difference in carriage prevalence of all genogroups of N. meningitidis between vaccinated and unvaccinated participants.
The use of videolarygoscopy (VL) as first choice for tracheal intubation versus direct laryngoscopy (DL) is a matter of debate. These two methods were compared in several studies. Videolaryngoscopes may reduce the number of failed intubations, particularly among patients presenting with a difficult airway. They improve the glottic view and may reduce airway trauma. DM is accepted as a risk factor for difficult intubation. The aim of this study is to compare VL to DL in adult patients requiring tracheal intubation for anesthesia, in terms of intubation success, glottic view quality, intubation failure, intubation time, conversion to another laringoscopy method and adverse outcomes related to tracheal intubation.
Patients with severe Chronic Obstructive Pulmonary Disease (COPD) and low oxygen levels in the blood are at risk of developing pulmonary hypertension and strain on the right side of the heart, both of which are known to increase symptoms and worsen prognosis It is not fully established whether interval exercise training in patients with severe COPD and concomitant low oxygen levels is beneficial. This study aims to evaluate the effects of aerobic interval exercise training in patients with severe COPD and low oxygen levels in the blood, with a particular emphasis on such effects on the cardiovascular system and pulmonary circulation.
Schizophrenia affects a significant proportion of the population and current levels of understanding of the illness is inadequate to treat it effectively. Converging lines of evidence suggest that neuroinflammation occurs in schizophrenia, and specifically over-activity of brain-resident immune cells called microglia. It is however unclear whether activated microglia play a primary role in schizophrenia, or whether this is a secondary phenomenon of no pathophysiological significance. The investigators therefore plan to test the effect of a monoclonal antibody (natalizumab) on psychotic symptoms in a cohort of first episode psychosis patients.
The occurrence of postoperative cognitive dysfunction (POCD) might be related to intraoperative cerebral desaturation. Positioning for neurosurgical procedures are associated with head rotation, elevation, flexion or extention that may affect blood brain inflow and outflow. Anatomical variations of Willis circle could affect the cerebral blood flow in extreme head position with the development of cerebral ischemia or functional changes of brain. Investigators suppose that detection of cerebral tissue desaturation and its prompt correction could modify the occurence of POCD after these procedures.
Randomized, double-masked trial designed to investigate the use of TLC399 (ProDex) in subjects with macular edema due to CRVO or BRVO.
This study aims to evaluate the efficacy of ultrasound derived variables in prediction of success of weaning from mechanical ventilation in critically ill patients with abdominal sepsis
The primary purpose of this pilot study is to evaluate the feasibility and acceptability of a Mobile Digital Solution in monitoring and collecting symptom burden data. The proposed study is meant to be the preparatory work for an intervention study to test the effect of Mobile Digital Solutions on improving patient outcomes by prompting early interventions for symptom relief and support of patient and family caregiver quality of life (QOL).
Background: Coronary artery bypass grafting (CABG) due to coronary artery disease (CAD) is one of the main surgical procedures performed in the area of cardiology. Individuals undergoing CABG present sarcopenia, decreased muscle strength of the lower limbs, decreased respiratory muscle strength and dyspnea due to immobility in the bed and the inherent conditions of the disease itself. Cardiorespiratory rehabilitation techniques are rarely used with measurement in hospitals and can greatly favor an early and effective reestablishment to this population in several parameters. Objective: To evaluate the effect of functional electrical stimulation (FES), ventilatory muscle training (TREMVEN), early aerobic training (AERO) and isometric handgrip training (ISO) on the functional capacity, endothelial function and cardiac parameters of individuals undergoing CABG. Methods: In a randomized clinical trial, volunteers will be allocated into four groups: EEF, TREMVEN, AERO or ISO in the preoperative period of CABG. After 48 hours (postoperative midway) of the surgery, the protocol will begin until after hospital discharge. The endpoints evaluated will be: functional capacity, respiratory muscle strength, systolic and diastolic function, arterial endothelial function, inflammatory profile and plasma levels of vascular endothelial growth factor (VEGF). Scientific contributions: Phase 1 cardiorespiratory rehabilitation with alternative interventions may provide an increase in functional capacity, strengthening of respiratory muscles, improvement in cardiac and endothelial functions, as well as increased systemic VEGF levels (myocardial revascularization) and improvement of the inflammatory profile, effectively forwarding the individuals to the rehabilitation phase 2.
RATIONALE: Placing a tumor antigen chimeric receptor that has been created in the laboratory into patient autologous or donor-derived T cells may make the body build immune response to kill cancer cells. PURPOSE: This clinical trial is studying genetically engineered lymphocyte therapy in treating patients with B-cell leukemia or lymphoma that is relapsed (after stem cell transplantation or intensive chemotherapy) or refractory to chemotherapy.
