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 our study is correlate between premature delivery (between week 23-35 of the pregnancy) in women that had intercourse up to 12 hours prior to beginning of labor and polymorphisms in the gene Prostanoid receptor.
Mucositis and xerostomia are the most common complications of head and neck (H&N) irradiation, and the combination of chemotherapy and radiation therapy is associated with a significantly higher rate of complications. Mucositis usually develops during the second or third week of a course of standard radiotherapy, and the pain it causes peaks between the third and last week of treatment. The pain then persists for at least one month following the completion of therapy, and may be so overwhelming that it prevents patients from swallowing food and fluids. The patient is therefore at a risk to develop malnutrition, and must be treated vigorously. In this respect, the use of gastrostomy tubes (PEG) has been shown to be beneficial. Completion of the full course of irradiation, without interruption, is important for achieving best possible results in cancer of the H&N. It is therefore essential to identify and refer patients at risk to receive effective and timely nutritional intervention. Since mucositis represents a clinical continuum which differs between patients, it is difficult to assess before-hand which patients will be at risk. There is no simple laboratory tool available, which could predict which patients are susceptible to develop severe mucositis and dysphagia, and eventually will require a feeding gastrostomy. The first phase of mucositis, inflammation, results in the production of pro-inflammatory cytokines such as interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α). In general, the inflammatory cytokines IL-1, interleukin-6 (IL-6) and TNF-α are elevated in inflammatory conditions and are found in increased levels in blood and tissue fluid during inflammation, while anti-inflammatory cytokines are produced in a decreased manner. The main purpose of this study is to find the best indicators and prognosticators of mucositis occurring in the healthy oral tissues of H&N cancer patients receiving treatment, and to understand the cytokines balance mechanism of action. Assuming there is a correlation between high cytokines levels during inflammation and the severity of radiation induced mucositis, finding these prognostic factors may help us predict during the first part of the treatment the need for PEG, placing it prior to the complications associated with severe mucositis on one hand, and avoiding unnecessary procedures on the other hand.
This research project addresses the hypothesis that a neurocognitive profile characterized by impairment of response inhibition and sustained attention may be a risk factor for smoking initiation and nicotine dependence among young women. Nicotine has short- term, facilitating effects on attention and response inhibition. Therefore, individuals who are impaired on cognitive functions such as these and initiate cigarette smoking may be more likely to maintain the habit and develop nicotine dependence. The research protocol specifically tests whether administration of nicotine to non-abstinent, regular cigarette smokers improves cognitive function in those domains where the participants had previously been shown to manifest performance deficits
the purpose of this study is to determine whether children who are hospitalised waiting for cardiac surgery for several days in pediatric or pediatric surgery department acquire resistant microbial flora, thus necessitating broad spectrum antibiotics for perioperative prophylaxis.
The purpose of this study is to perform cardiac evaluation in HIV-1 (predominantly clade C)infected children by history, physical examination, echocardiogram and plasma N-terminal pro-B-type natriuretic peptide (N-BNP)measurement in order to determine asymptomatic abnormalities.
Osteoarthritis is the most common disease effecting human beings with incidence of about 20% and prevalence close to 80% of the adult population. It is most common after the age of 60 years and more in females with the ratio 4:1 F:M. Osteoarthritis Can be present in every hyaline joint, but is mostly damaging to the weight bearing joints, the knees and hips. At the final stage of cartilage destruction (from wear and tear) joint replacement is the solution. Since these operations were introduced about 50 years ago, the indications and the number of yearly procedures has been increasing with alarming speed. Last year in the united states, about 500,000 Total Knee procedures were done, exceeding Total Hip replacements. By 2030, close to 4.5 million joint replacement procedures are expected in the United States, the majority of which will be knee replacements. Joint replacement is the solution for the final stage of damaged cartilage. In early and advanced stages of cartilage wear and specifically in the knee H.A. acts as an anti inflammatory and lubricant agent, reducing the knee pain and improving knee motion and function. The biological effect of H.A. is well documented in clinical studies and less with scientific evidence derived from patients themselves. Our study proposal briefly is, as follows: 60 patients with evidence of osteoarthritis of the knees will join the study after I.R.B. (Helsinki Committee) approval. All of them will be examined, x-rays will be performed and blood tests will exclude patients with infections or inflammatory disease. A V.A.S. (Visual Analog Score) and SF-36 evaluation form will be completed prior to each intraarticular injection, in addition to a complete medical examination. The enrolled patients will receive the usual three intraarticular knee injections of H.A.(Arthrease), but prior to each injection, the joint will be aspirated and the joint fluid will be analyzed for Chondroitin sulfate type I and type II as described further in this project. Three and six months after the third initial injections, the patients will recalled and joint fluid will be aspirated again, followed by an H.A. injections, if symptomatic. This study is the only one ever proposed, for evaluating joint debris qualitatively and quantitatively. It will provide clinical information as well as objective data on the preservation of the joint cartilage. Hopefully, this study will provide additional information such as the relationship between the presence of debris and symptomatic vs. asymptomatic patients. It may help in determining how long the injected H.A. has an effect and whether serial and periodical injections are indicated. Inclusion criteria: 1. patients with the diagnosis of Osteoarhtritis of the knee, graded according to Kellgren as grade 1-4 Exclusion criteria: 1. Patients that suffer from acute septic arthritis. 2. Patients that treated with coumadin and/or other anti-coagulant drugs 3. Patients that show mental or physical conditions, which preclude compliance with study and/or device.
There is a simple laboratory technique for localization of caries associated bacteria on tooth surfaces by taking an impression of the teeth with a material containing sucrose. The purpose of this study is to check whether the technique can be incorporated into dental clinics as diagnostic tool comparing to other diagnostic methods available.
In patients with prostate cancer with indolent features, disease progrssion may be very slow and in many cases will never become clinically evident during the patient's lifetime. Active surveillance is a continuous process of monitoring disease characteristcs aiming to avoid the morbidity of active therapy in patients with stabe indolent parameters, while offering early detection of disease activity in others who will need active therapy to control their disease. We hypothesize that active surveillance will permit the avoidance of therapy related morbidity in the majority of appropriate patients and will be associated with maintaining their quality of life.
Olive oil and Omega 3 have many anti inflammatory effects that may be beneficial in the inflammation and edema of chronic stasis dermatitis. The olive oil contains many mono unsaturated fatty acids and anti oxidants that may add to the well being of a diseased skin by improving cell membrane homeostasis.
