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 purpose of this study is to investigate the extent of return to work (RTW) after traumatic hand injury and to identify factors that are related to RTW.
Asthma is a major health problem worldwide. The measurement of fractional exhaled nitric oxide (FENO) has been established as a valuable non invasive and simple tool in the diagnosis of asthma and may also act as a useful surrogate inflammatory marker on which to base treatment decisions in asthma management algorithms. The measurement is useful also in other respiratory diseases. Current methods of measuring FENO include on line measurements by heavy duty expensive analyzers which are not widely and easily available. Off line measurements of breath samples which can be analysed later may be a simple solution. We hypothesize tha toff line measurements of NO will be as reliable and valid as those measured on-line
Hypothesis: Inflatable intra medullary femoral nailing is superior to DHS in terms of blood loss, operative complications and postoperative rehabilitation in the management of pertrochanteric femur neck fractures.
An examination of the various factors that cause lower back pain in nurses in four hospitals in Israel such as; socio-demographic, professional, posture while ambulating patients and job environment.
Pain, a subjective sensation, has been increasingly studied, as it has been recognized as an important factor in patients' recovery and quality of life. Pain is charted today as one of the vital signs. For standardization, pain is charted by a number from 0 to 10 indicating its level. The most common practiced pain assessment tool today is the VAS- Visual Analog Score (facial or numerical), by which the patient himself indicates the level of the pain he or she endures. It has been found that the correlation between the reported pain by the patient and the assessed pain by the caregivers or the medical personnel becomes poor as pain intensifies. Objective assessment of anesthesia using the heart rate and its spectral analyses was done in the past. By using this modality, works on neonatal pain were conducted. In adults, works have shown that there is possibility to assess pain using this modality, though no repeated proof for its ability to detect pain was published. We know that physiological signals such as ECG consist of mixtures of variety of patterns and phenomena accruing at different patterns and time points. Traditional analysis methods are designed and optimized to handle signals that include a single class of patterns such as pure harmonics or piece-wise constant functions. However, such basic operations that use a single representation method usually yield mediocre results when applied to real complex biological signals as ECG and EEG especially in the case where the Signal to Noise Ratio (SNR) is very low. Recent trends in digital signal processing (DSP) use the novel idea of merging several different representation methods to create a so called over-complete dictionary, examples of this approach include the Matching Pursuit algorithm and the Basis Pursuit algorithm. We intend to develop and apply the novel signal processing tools to the ECG signals for the first time. We believe that such tools have the potential to provide much better insight of the signal basic components and their relation to pain.
The purpose of this study is to determine if endoscope with NBI(narrow banding imaging)can detect intestinal metaplasia( consider pre malignant condition) and use a targeting biopsy in case of suspected intestinal metaplasia
During 1987-1991, WHO supported studies of exposures and short term neurobehavioral effects in a cohort (n=200) with occupational and community exposures to pesticide drift containing organophosphates from orchards and cotton fields in the Hula Valley. We aim (1) to re-examine neurobehavioral outcomes in members of the original cohort and (2) to examine cognitive effects in children with residential exposures. In adults, we will carry out assays of alkyl phosphates, PON1 (paraoxonase-1), NTE (Neuropathy Target Esterase), neurobehavioral tests of cognitive and performance skills, nerve conduction measurements and mood status. We will carry out Psycho-Didactic tests in children. The findings will advance knowledge on delayed term health effects of lengthy everyday exposure to OP pesticides and guide regulatory policy.
Total joint arthroplasty are common operations among the elderly population. The postoperative patients' rehabilitation process may be influenced by a variety of factors, such as age, BMI, perioperative hemoglobin levels, pain perception, comorbidities, etc. Nevertheless, only a few well controlled studies evaluated the effect of various factors on patients' rehabilitation short-term outcome. Furthermore, no scale has been developed, that can predict patients' rehabilitation and functioning levels 6 weeks postoperatively. In the current study we wish to evaluate the effect on patients' function that the following factors have: age, BMI, admission and discharge hemoglobin levels, pain perception, type of operation (TKA versus THA), intensity of postoperative physiotherapy, involvement of other joints by the primary pathology, comorbidities, and self assessed health status. In order to quantify patients' level of functioning, several tests will be used: hand grip strength, Timed up and go test (TUG) and Oxford knee and hip score. The factors that will be found statistically significantly associated with level of functioning, will be used in an attempt to develop a scale that will predict the level of functioning 6 weeks postoperatively. Such a scale can allow preoperative identification of patients at high risk of postoperative low functioning levels and the application of a unique rehabilitation program, for only these patients, in order to optimize their functioning.
Background: Infertility affects up to 15% of married couples. About half are attributable to female factors, among which anovulation is the leading cause. Some 5% of all women of reproductive age are anovulatory due to the polycystic ovarian syndrome (PCOS). PCOS causes also major health and cosmetic problems and significantly affects quality of life. PCOS is associated with cardiovascular morbidity and Type 2 diabetes mellitus, but it is unclear whether these are caused by the ovarian dysfunction or result from a common denominator. Working hypothesis and aims: Whole genome analysis of multigenerational families in which at least one woman is affected by PCOS may significantly reduce the numbers needed to verify the specific genes, involved in the causation of PCOS. Methods: Registration of multigenerational families and production of personal files with full workup for the presence of PCOS or its absence (in the women participants). Drawing of blood, extraction and preservation of DNA. Analysis of all informative SNPs in the genomes of the participants on a specific microarray chip. Statistical analysis of the results. Expected results: Verification of the loci and putative genes, associated with the appearance of PCOS. Importance: Elucidation of the specific genes underlying the pathology of PCOS. Probable implications to Medicine: Paving the way for targeted treatment of the problems, associated with PCOS, based on the clear knowledge of its underlying cause(s).
In this study we intend to randomly assign each parturient one of two commonly used oils to be applied during the second stage of labor, one of them containing vitamin E. We will verify if perineal massage increases the chances of delivering with an intact perineum comparing the two oils. As secondary objectives, we will evaluate the effects of perineal massage on specific tear location, the severity of perineal tears and the amount of suture material required for repair.
