Filter by:Ultravist is an iodine-based contrast agent that helps to make medical imaging scans clearer. It is also called iopromide, and it is available for doctors to give patients before they have scans. Even after a treatment or substance has been approved for use, researchers continue to study it to learn more about its safety. Researchers have done studies on the safety of Ultravist, but they want to learn more about specific medical problems called hypersensitivity reactions (HSRs). These are undesirable immune system reactions to the study drug. In this study, the researchers will compare the risk of HSRs in children and in the elderly to the risk of HSRs in middle aged adults. The researchers will look at information about medical problems that happened in people in 4 other studies. These studies are called PMS I, IMAGE, TRUST, and Ultravist in CT. A total of about 139,000 people will be included in this study. All of the people in the earlier 4 studies received Ultravist as an injection into the vein or artery before having a scan. In this study, the researchers will compare the number of children, middle aged adults, and elderly patients who had HSRs after receiving Ultravist.
Food allergy is a global burden, affecting patients, society as a whole and the economy. For most common food allergies, patients synthesize specific IgE-antibodies against harmless food proteins. Clinical phenotypes of food-allergic patients are highly diverse. Differences in medical symptoms (organs, severity, delay), threshold and cross-reactivity levels suggest variable underlying endotypes. The aim of this study is to identify phenotypic biomarkers for advanced stratification of food-allergic patients. Our study will consist of up to 50 participants (30 food-allergic, 20 tolerant), recruited in Luxembourg. Clinical samples will be collected before, during and after the event of a double-blind placebo-controlled food challenge for patients. Multi-omics analyses of blood (sera, peripheral blood mononuclear cell, basophils) and stool will allow a deeper understanding of the underlying immune mechanisms, including allergen metabolism aspects, as well as the functional gut microbiome. Deciphering these basic aspects during the present pilot study is expected to pave the way towards novel personalized medicine approaches for diagnosing and treating of food-allergic individuals. This study is a cooperation project between the Centre Hospitalier de Luxembourg (CHL), the Luxemburg Institute of Health (LIH), the University of Luxembourg and the Integrated Biobank of Luxemburg (IBBL).
This is a phase 1, multi-center, randomized, double-blind, placebo-controlled study in adult participants with peanut allergy. Participants will be randomized in a 3:1 ratio to receive either an escalating dose of INT301 or placebo. The treatment group will be blinded to the investigator, participants, and the Intrommune study team.
To gain insights on the application, use and effectiveness of Frisolac Gold Intensive HA and Frisolac Gold PEP AC with reference to improvement of CMPA symptoms and to determine the methodology used by Mexican Health Care Professionals (HCPs) in the clinical practice (i.e. diagnosis and dietary management) of CMPA in Mexican children (≤24 months) diagnosed with or suspected of CMPA.
Dentin hypersensitivity (DH) can be defined as acute, short-duration pain from open dentin tubules in exposed dentin. The symptom of DH is subjective and varies from patient to patient and may present as mild discomfort or as a high-intensity pain, which can affect the individual's quality of life, interfering with their eating and hygiene habits. One approach to treatment would be the use of agents that chemically desensitize sensory nerves, blocking the transmission of nerve stimuli to the central nervous system. The effectiveness of desensitizing treatments is influenced by several factors present in the oral cavity, which can contribute to a greater effect of these agents but can also be responsible for removing them from the dental surface. To date, studies have been carried out in the short term, not exceeding an average period of 12 weeks, so there is no consensus on the technique or agent that will guarantee the most effective and lasting effect against DH, not even the ideal period for reapplication. Thus, more studies are needed to assess the clinical behavior of desensitizing products on the market, especially the most recent releases. Therefore, the aim of this study was to clinically compare the effectiveness of different office treatments for DH, being ClinproTM White Varnish, ClinproTM XT Varnish, and a control group (placebo) through pain assessment with the Visual Analog Scale (VAS), after stimulation with air from the triple syringe.
Subjects will be enrolled into 3 balanced groups each using a different strength toothpaste. Dental hypersensitivity (DHS) will be assessed at study start, midway and study end.
The aim of this study is to determine the effect of advocacy education on social justice advocacy skills and ethical sensitivity in undergraduate nursing students.
In this study researchers want to study the potential skin reaction after repeated application of an antifungal cream containing trolamine. The study plans to enroll about 32 healthy female or male participants with the age 18 - 79 years. Researchers will apply on the skin of the upper back between the shoulder blades of the study participants three different patches to cover a small amount of the antifungal cream or 0.3% solution of sodium lauryl sulfate, which is known to cause skin irritation (so called positive control). A third patch will cover a skin area without any product (so called negative control). Participants will return daily to the study center to have new patches containing the test products applied on the same skin area of the back, excluding weekends, for 21 days of continuous skin contact. At each visit the skin will be investigated by the researchers for redness, dryness and other reactions to learn about the skin reaction after repeated application.
In this study researcher want to learn more about possible skin reactions such after repeated application of an antifungal cream containing Trolamine. They are especially interested in skin irritations or allergic skin reactions. The study plans to enroll about 225 female or male participants with the age 18 - 79 years. The antifungal test cream will be applied on the back between the shoulder blades of the participants and covered by a special dressing patch. This will be repeated 3 times a week for the first 3 weeks of this study applying the cream on the same area of the back. At each visit the skin will be investigated for redness, dryness and other reactions. After a rest period of two weeks the test cream will be applied on the same skin area as before and on a second new skin area nearby. After 2 and 4 days the two skin areas will again be investigated for redness, dryness and other reactions.
This 12 week placebo-controlled study evaluates the efficacy and safety of E. hallii supplementation.
