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 prevalence of IBS in the community has been reported in numerous cross-sectional surveys. However, less is known about the incidence of IBS ,mainly due to its slow development and to patients under-reporting. Furthermore, only one study has analyzed data concerning potential risk factors for the diagnosis of IBS. The investigators will examine the incidence of IBS in a large cohort of young adults and will look at the association of socioeconomic, anthropometric and occupational factors with IBS incidence.
To evaluate the safety and tolerability of afatinib (Giotrif) in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) harboring EGFR mutation(s) and have never been treated with an EGFR-TKI
Lung cancer is the most lethal cancer, killing ~1.3 million people worldwide every year. Early diagnosis could increase its survival by 3-4 folds. Therefore the yield of screening for lung cancer is not a question anymore and the urgent unmet need is to define the group that is under a high risk for lung cancer. Our lab is focusing on revealing non-invasive biomarkers as for early detection of lung cancer. This study specifically focuses on biomarkers that are found in exhaled breath. These biomarkers are known as volatile organic compounds (VOCs).The VOCs' profile can discriminate between those who suffer from lung cancer and healthy individuals. It is well established that a cancer cell can activate their glycolysis (glucose degradation) pathway in order to survive. This links malignant processes with this basic biochemical, metabolic cycle. This study will focus on the unique processes incurred by glycolysis in the tumor cells and its effect on the surrounding environment. By better understanding and revealing the exact mechanism, it will become possible to identify the biomarkers released by malignant cells that use glycolysis as a source of energy. This study's goal is to identify and analyze those distinguishing VOCs. The hope is that these VOCs will provide a new innovative possibility of developing the so desperately needed, early-detection lung cancer screening method. This research will collect and analyze the exhaled breath of participants. The exhaled breath will be obtained before and after a glucose challenge test, in which the participant is asked to drink a solution containing water and glucose. This study will involve a total of seventy participants, fifty of which currently suffer from active lung cancer, while the remaining participants belong to a high-risk group.
Pelvic organ prolapse is a common disorder that results in significant patient morbidity. Approximately 1 in 9 women undergo surgery for the correction of pelvic organ prolapse (POP) and associated bladder and bowel dysfunction. Despite its common occurrence, the cause of POP remains largely unknown. Prolapse is thought to be caused by direct injury to the levator ani (LA) muscle, denervation of the pelvic floor musculature, or fascial damage incurred during childbirth trauma. The sacrospinous ligaments are commonly employed surgical structures employed to repair vaginal prolapse. Despite the frequent use of these structures in prolapse surgery, there is a paucity of information regarding the identification of these structures outside of surgical dissection. Furthermore, there is no published data describing the relative distances between the apex of the vagina and these ligaments in women with prolapse. Recent developments in imaging have enabled the identification of the distal subdivisions of the levator ani, classifying as: pubovaginalis, puboanalis, and the puboperinealis as the subdivisions of the pubovisceralis. The visualization of these structures is possible using a 3D ultrasound technique (BK medical, Wilmington, MA), that has been validated in cadavers and in live humans, with excellent interrater reliability. The investigators propose to use this technology to explore the anatomy of the sacrospinous ligaments.
The purpose of the study is to extend the use of opicapone 25 or 50mg once per day by subjects who participated in the BIA 9-1067-302 clinical trial according form 4a for additional three years.
The role of alpha2 receptor agonist on pain perception and modulation will be examined. In addition whether this is mediated through the opioid system will be examined. Pain perception and modulation will be examined before and after administration of Clonidine or placebo together with Naloxone or saline.
Background: - Optic neuritis often is a symptom of multiple sclerosis (MS). Many people who experience optic neuritis are later diagnosed with MS. MS disease activity seen on magnetic resonance imaging (MRI) scans is often greater than that seen in tests given during regular doctor's visits. Even though MRI is a helpful tool for studying optic neuritis and MS, more information is needed on how MS symptoms show up on MRI scans. Researchers want to use MRI scans to track changes in the optic nerve after an optic neuritis episode. This approach will help them study the relationship between optic neuritis and MS. Objectives: - To collect more information about the relationship between optic neuritis and multiple sclerosis. Eligibility: - Individuals between 18 and 50 years of age who have new optic neuritis. - Individuals between 18 and 50 years of age who have new symptoms of MS other than optic neuritis. - Healthy volunteers between 18 and 50 years of age. Design: - Participants will be screened with a physical exam and medical history. They may provide blood or urine samples. - Participants with optic neuritis or other MS symptoms will have a baseline study visit. They will have a physical exam and full eye exam. To look for signs of MS, they will have evoked potential tests to see how the body responds to stimulation. They will also have an MRI scan to study any changes in the brain and optic nerves. - After the first visit, participants will have steroid treatment for 5 days for the optic neuritis. - Additional study visits will be given 1, 3, 6, 9, and 12 months after the baseline visit. The tests from the first visit, including the MRI scans, will be repeated at these visits. - Healthy volunteers will have a baseline study visit. They will have a physical exam and full eye exam. They will have evoked potential tests to see how the body responds to stimulation. They will also have an MRI scan to study any changes in the brain and optic nerves. - Healthy volunteers will have additional study visits 2 and 11 months after the baseline visit. The tests from the first visit, including the MRI scans, will be repeated at these visits.
The purpose of this study is to determine the effect on the (carbon 13 labelled(13C)-Methacetin Breath Test (MBT) of i.v. propranolol, a non-selective beta blocker (NSBB) following initial administration and after chronic use of each of these agents. The correlation of the MBT with Hepatic Venous Pressure Gradient (HVPG) measurement before and after treatment will be assessed. Additionally, the MBT measurements following 60 days of therapy will be compared to the first MBT measurement and to the second MBT measurement, post HVPG. Each patient's subsequent MBT measurement will be compared to his previous MBT results in order to determine his/her response to therapy.
This is a prospective, single-arm, open-label, non-randomized study. The aim of the study is to assess the safety and efficacy of the Prow LIF procedure in Transforaminal Lumbar Interbody Fusion (TLIF) procedures for the treatment of subjects with symptomatic degenerative disc disease (DDD).
Female inability to conceive a child. The purpose of this randomized, two-arm and double blind, double dummy study is to demonstrate that the treatment of a daily dose of 3x10mg dydrogesterone orally is as effective and safe as the daily dose of 3x200 mg micronized progesterone capsules administered intravaginally for the luteal support in patients undergoing IVF. The treatment will start on the day of oocyte retrieval and continue until pregnancy is negative or until week 12 gestation.Patients will be followed after treatment until 30 days after delivery to record any safety and tolerability data of the patient and their newborn(s).
