Filter by:Among the psychiatric symptoms observed in the premotor phase of Parkinson's disease (PD) and/or in "de novo" patients, apathy is relatively frequent (estimated to 23%). However, the neuropathological bases of apathy are still unknown. However, recent data suggests that apathy could be linked to a more specific dopaminergic denervation in the ventral striatum. Rasagiline increases the bioavailability of striatal endogenous dopamine by blocking the MAO-B. Some recent data suggest rasagiline could be effective to improve apathy in Parkinson's disease. The primary outcome is to demonstrate a significant reduction of apathy using the Lille apathy rating scale (LARS) in drug naive patients with early diagnosed Parkinson's disease, using a treatment by rasagiline.
There is an urgent need to control the current national outbreak of Carbapenem-resistent Klebsiella pneumonia (CRKP). In Israel, the death rate among CRKP carriers is 3.5 times higher than in Carbapenem-sensitive Klebsiella pneumonia carriers (44% vs. 12.5%, respectively). In the investigators' previous study: A Randomized, Double-Blind, Placebo-Controlled Trial of Selective Digestive Decontamination (SDD) Using Oral Gentamicin and Oral Polymyxin E for Eradication of CRKP Carriage (Infect Control Hosp Epidemiol. 2012;33:14-19) the investigators have shown that the investigators' SDD regimen is effective for decolonization patients colonized with CRKP. The investigators' assumption is that a higher dose of polymyxin E together with gentamicin (SDD drugs) for a prolonged period is needed to overcome the likelihood of a high rate of drug inactivation in the gut, thereby reaching CRKP carriage eradication.
It is established that the surviving patients after a stay in the ICU are characterized by frequent malnutrition and morbidity and mortality. The main goal of this work is to study the relationship between nutritional statuses during ICU hospitalization, whatever its determinants, and quality of life, morbidity and mortality at one year. The hypothesis of the study is that the presence of under nutrition is responsible for a 10% increase in crude mortality at one year (which would be respectively 30% for malnourished patients and 20% for non-malnourished patients).
Pseudomonas is a common and virulent respiratory bacteria in patients with Cystic Fibrosis (CF). With time, the infection with Pseudomonas becomes chronic and very difficult to eradicate. The standard treatment of chronic Pseudomonas infection is inhaled Tobramycin which is given every other month.. Inhalation of Tobramycin was proven as an effective treatment that improves the respiratory function and reduces the concentration of bacteria in the sputum. However, inhaled treatment lasts between 15 to 30 minutes twice a day and therefore adherence is a major problem. The effect of switching from inhalation treatment to inhaler treatment on patient's adherence and quality of life has not been studied.
The aim of the study is to investigate the efficacy of trans-cranial magnetic stimulation in treating attention deficit disorder in adults.
The Israel Terminally Ill Law, 2005 allows patients who are terminally ill and ventilated to have their ventilator placed on a timer which at a specific time in the future stops the ventilator, maintains the patient on positive pressure (CPAP) and allows the patient not to be reconnected to the ventilator. We will evaluate the safety of the Automatic Respiration Transfer-Timer by assessing vital signs, oxygenation and ventilatory pressures and volumes during the use of the timer with the regular ventilator. In addition, we will evaluate whether the timer stops the ventilator and switches to CPAP at the designated time.
The biological membranes that surround a cell and its organelles are important to the overall function of the cell. Fatty acids are the main structural components of a membrane, and the presence of certain fatty acids can alter a membrane's characteristics, which subsequently alters its function. Two fatty acids that are of particular interest to researchers are eicosapentanoic acid (EPA) and docosahexanoic acid (DHA). These omega-3 fatty acids have unique unsaturated structures, and their incorporation into biological membranes appears to elicit potent physiological effects. The body is unable to intrinsically synthesize these important fatty acids, so they must be obtained from the diet or through supplementation. EPA and DHA supplementation has been reported to provide numerous positive health benefits, including decreased blood pressure and an improved blood lipid profile. Recent research in our laboratory has demonstrated in young men that resting metabolic rate was increased following a 12 week period of omega fatty acid supplementation of 3 g/day. Fat utilization was also increased and carbohydrate use was decreased both at rest and during a 1 hr moderate exercise challenge. These findings have positive implications for people who are interested in losing weight, but it not known whether these effects occur in older adults. With age, body composition changes (increase in fat mass and decrease in lean mass) occur which may negatively affect general health, particularly normal physical functioning and quality of living of the older adult. The potential role of omega 3 fatty acids to increase fat oxidation and increase resting metabolic rate may be a therapy for decreasing fat mass in the older adult. Research has suggested that omega 3 fatty acids may elicit an additional therapeutic role by reducing joint pain. Another aspect of aging is a loss in lean body mass, which is associated with an attenuation of skeletal muscle protein synthesis in response to nutritional stimuli (amino acids and insulin). The weakened anabolic response is considered to be partly due to defects in the anabolic signaling cascade in the muscle. Research in older adults has reported an increase in muscle protein signaling with EPA and DHA supplementation in response to a nutritional challenge. However it is unknown whether the increase in protein signaling results in an eventual increase in lean body mass. The physical functioning of older adults is not only influenced by body composition changes, but also age-related neuronal changes that affect the velocity of axonal conduction and influence the ability of the muscle to generate torque and the rate at which the torque is developed. Muscular strength and functional capacity increases have been reported with chronic resistance exercise in a cohort of older women supplemented with EPA and DHA. However, the effect of EPA and DHA intake on physical strength in older adults with previously low EPA and DHA consumption, independent of exercise, is currently unknown. Therefore, the purpose of this study is to determine the effects of 12 weeks of omega-3 supplementation at 3 g/day on metabolic and physical health parameters in community-dwelling older adults. We hypothesize that EPA and DHA supplementation will result in 1) a decrease in resting heart rate and blood pressure; 2) a more healthy blood profile; 3) an increase in resting metabolic rate; 4) a greater reliance on fat oxidation for energy both at rest and during exercise; and 5) a decrease in fat mass; and 6) an increase in lean mass, strength and physical function.
This study will test that hypothesis that endoscopic lung volume reduction therapy performed using emphysematous lung sealant treatment can be improved using smaller doses delivered to more a larger number of treatment sites.
The investigators will follow up on babies that had prenatal diagnosis at 2nd or 3rd trimester of normal width and asymetry of lateral brain ventricles
Get a better understanding of the pathophysiological processes of acute respiratory failure following cardiopulmonary bypass to initiate timely therapies targeted on a cell line. Demonstrate that there is a relationship between increased transpulmonary gradients of inflammation biomarkers (sRAGE, sICAM-1, SPB, PAI-1, ROS) and pulmonary vascular resistance on the one hand and alveolo-capillary gas exchange on the other hand after cardiac surgery under cardiopulmonary bypass.
