There are about 9745 clinical studies being (or have been) conducted in Israel. 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.
The investigators have previously shown that a frequency of 15.95-16.00 Hz protects against acute myocardial infarction in rats. In the current study the investigators would like to investigate whether this frequency enables cardiac patients with exercise-induced chest pain to exercise at higher workload and heart rate. Therefore, patients will undergo two exercise stress tests, one test after being exposed to 30 minutes of the above mentioned frequency and another test after being exposed to sham (no frequency is turned ON). The investigators will measure changes in the electrocardiogram (ECG), workload, exercise time, and subjective measure of chest pain (angina).
The study hypothesis is that urine concentrating ability can predict the rate of kidney function decline. Patients with kidney disease at the investigatorsclinic will be asked to give first morning urine sample and osmolarity will be measured. The investigators will follow up kidney function decline and check if there is association with urine osmolarity.
The investigators will try to find any efficacy of platelet rich plasma injection for the treatment of osteoarthritis (OA) in the subtalar joint. Autologous platelet-secreted growth factors (GFs) may have therapeutic effects in OA capsular joints via multiple mechanisms. The investigators aim is to examine the effect of a platelet-derived preparation rich in growth factors(PRGFs) in OA of the subtalar joint, using parameters of pain, function, quality of life and safety.
Abstract Background: Vitamin D affects a wide variety of functions in the body including regulation of calcium, phosphorus, and bone metabolism. Israeli studies have documented a high prevalence of Vitamin D deficiency in Israeli infants in general, which was more severe in infants from Ultra-Orthodox Jewish families. Modest dress requirements in this population drastically reduce sun exposure, known to encourage production of Vitamin D. Countless research has analyzed preterm as well as term neonates born to mothers with vitamin D deficiency, with regard to weight, height, and bone mineral density at birth. However, there is a paucity of information about healthy infants' vitamin D levels and its' correlation to these parameters during the first few years of life. Objectives: The purpose of the proposed study is to measure and correlate levels of 25(OH)D and bone mineral density towards the end of the first year of life with growth rates and bone mineral density in the same children at the ages of 2, 3 and 5 years. Patients and Methods: The study will be performed in the Ultra-Orthodox Jewish community of Beitar Illit. 25(OH)D levels will be taken between 9-12 months of age (when routine blood tests are normally drawn for these infants) and bone mineral density will be measured using Quantitative Ultrasound. Infants will be divided into 2 groups: those with those with normal 25(OH)D levels (>15ng/ml), and those with 25(OH)D deficiency (<15ng/ml). Group 1- normal levels will receive no intervention. Infants with 25(OH)D below 15ng/ml will be randomly assigned into one of two groups; Group 2-those receiving continued vitamin D supplementation of 800 international units(IU) (4gtt/d) for one year, or Group 3- those receiving the placebo. Height, weight, and head circumference growth curves will be recorded every two months until 2 years of age. Quantitative ultrasound, growth charts and blood tests including 25(OH)D, serum calcium and phosphate levels, Parathyroid hormone (PTH), and alkaline phosphatase, taken at approximately 9-12 months will be repeated at 2 years of age. At that time children from Group 1 (no supplementation) will be divided into three: Group 1a- normal 25(OH)D levels will continue with no intervention, Group 1b <15ng/ml will begin receiving vitamin D 4gtt/d, Group 1c <15ng/ml will receive a placebo until age three. Groups 2 and 3 will continue their previous treatment until age three. All aforementioned tests will be repeated at age 3, when treatment will stop, and the same tests will be repeated at age 5.
This study will expand the understanding of factors associated with adherence to self care and the diabetes control among diabetes type 2 patients. The theoretical framework of the study incorporates central variables from two theoretical models: a cognitive model of health behavior - "Health Belief Model", and the Stress and Coping model. The study is innovative in its focus on the association between the patient's attachment style and adherence to self care and diabetes control, a topic less studied among diabetes patients, in addition to cognitive, social and emotional variables. Further emphasis is upon a comparison of the study model between males and females.
The purpose of this randomized controlled trial in patients undergoing cardiac surgery is to show that a 3rd generation HES (Hydroxyethyl Starch) solution - Tetraspan® is as good as in terms of safety and effectiveness as the commonly used albumin based solution for volume replacement after the surgery.
This study will examine the efficacy of group therapy utilizing the Existential Approach in heart failure patients when compared to a control group of patients who are waiting for the same group treatment. This comparison will be achieved by measuring changes in the variables studied namely, the levels of psychological distress and levels of psycho-social adjustment.
Phenotype characterization of shortness of breath of pediatric emergency room patients by objective wheeze and cough monitoring improves diagnostic and severity assessment accuracy and correlates with overall patient outcomes.
People with respiratory infection, asthmatic patients and cystic fibrosis (CF) patients suffer from a multitude of pathologies of airways and are often inflicted with chronic cough. Treatment of cough in these patients consists of many types of expectorants, cough suppressors, secretion modifiers, inhaled bronchodilators etc. In addition, chest physical therapy (PT) is often prescribed as part of the treatment regime. The assessment of coughing is currently subjective and based on the symptoms qualitative description as expressed by the patient or parent. Quantitative and objective methods for cough assessment are not available beyond the investigative laboratory and are unique to the specific investigator.
The study will examine the influence of a Cognitive Behavioral Therapy (CBT) short-term group intervention program on the levels of psychological stress and professional exhaustion experienced by the nursing staff in a cardiac department.
