A Phase III, randomised, double-blind, placebo-controlled, multi-centre study to assess the efficacy of olaparib maintenance monotherapy in relapsed high grade serous ovarian cancer (HGSOC) patients (including patients with primary peritoneal and / or fallopian tube cancer) or high grade endometrioid cancer with BRCA mutations (documented mutation in BRCA1 or BRCA2 that is predicted to be deleterious or suspected deleterious (known or predicted to be detrimental/lead to loss of function)) who have responded following platinum based chemotherapy.
This is a randomized, double-blind, placebo-controlled, multi-center study comparing peanut oral immunotherapy (OIT) to placebo in the induction of tolerance and desensitization in peanut-allergic children. Eligible participants with peanut allergy will be randomly assigned to receive either peanut OIT or placebo for 134 weeks followed by peanut avoidance for 26 weeks.
Sensory disorders in patients with multiple sclerosis are among the most common symptoms encountered. A functional impairment based on sensory disorders of the hand. The hand is a sensory organ that transmits the cerebral cortex protopathic sensitive information, proprioceptive or epicritiques. The view-hand association plays an important role in the understanding of the environment. Its exploratory use remains an essential and voluntary basis. The process of recognition of the object passes through manipulation, but operates instantaneously. The brain is able to do a quick summary of the information it receives to determine the nature of the manipulated object. The exploration takes a posteriori, the brain can then determine the details component object (texture, shape, composition, temperature and weight). Neurophysiological mechanisms that would explain the analgesic effects of transcutaneous electrical nerve stimulation (TENS) are not fully understood. Several theories underlying its use as a neuromodulator of pain. The gate control theory has led to the development of TENS devices. Recruitment of myelinated, large caliber, by the TENS electrodes afferent fibers increases the control exerted on spinal level, thereby inhibiting the action of afferent fibers of small caliber related to nociception. This stimulation strengthens the blocking of "gate" at the corresponding cell bodies of spinothalamic tract and reduces the transmission of nociceptive impulses to the spinal cord dorsal horn. This is segmental presynaptic inhibition depends on the area and stimulated. The objective of this study is to improve the quality of life through improved sensitivity disorders of the hand in patients with MS, thanks to reeducation of the hand.
The aim of the study is to measure salivary fluoride and silver levels up to 7 days post-treatment. The participants will be 6 healthy adults. They will be given a fluoride free toothpaste to use the day before the study and all during the study. 3 participants will have 6 teeth treated (Group A).3 participants will have 28 teeth treated each on the facial aspect (Group B). On day 0, the participant will be given 25 ml of de-ionized fluoride free water to swish in the mouth and spit the entire contents into a 50 ml collection tube. This will be done 3 times. On day 0, 10 minutes after the rinsing and spitting, the participant will provide a unstimulated salivary sample into a universal collection tube until 5 ml are collected. The tubes with saliva will be stored on ice and then frozen at -20oC for transfer to the lab at the University of Washington. On Day 0, Isolation and application of silver fluoride. The quadrant will be isolated with cotton rolls, and surrounding gingiva will be covered with petroleum jelly to provide additional protection. After application, participant will be given 25 ml of fluoride free water to rinse as in 1 above and water collected. This will be done 10 times. DAY 1-6 Salivary Collection Measures: Fluoride will be measured using standard fluoride electrode analysis (Martinez-Mier et al., 2011). Silver will be measured using Inductively Coupled Plasma-Mass Spectrometry (EPA 6020a Rev.1 2007) at the University of Washington
Egg allergy is common in early childhood, affecting at least one in 50 preschool children. Influenza ("'flu") vaccines contain egg protein, as the vaccine is cultured in hen's eggs. There is robust data to support the safety of influenza vaccines (containing low or negligible amounts of egg protein) in patients with egg allergy. A new influenza vaccine, known as LAIV (Live Attenuated Intranasal Vaccine) has recently been approved by a number of licensing boards and is given by a spray into the nose. This new vaccine has been available in the United States for several years and is highly effective and against influenza infection, with an excellent safety profile in children without egg allergy. However, LAIV is also grown in hen's eggs and contains egg protein, and there are NO existing data on the safety of LAIV in egg-allergic children. The objective of this multicentre study is to assess the safety of intranasal LAIV in egg-allergic children, in order to demonstrate that these children can safely be given the new LAIV within a primary care health environment.
In patients with chest pain the diagnosis of a heart attack (myocardial infarction) is made where there is evidence of heart muscle damage using a blood test to measure the heart muscle protein troponin. A new a more sensitive troponin test may help us to identify patients with myocardial infarction more easily. The investigators propose to evaluate whether use of a novel high-sensitivity troponin test to lower the threshold for diagnosis of myocardial infarction is appropriate. If increased sensitivity does not reduce specificity for the diagnosis, then this new test will improve patient outcome through better targeting of therapies for coronary heart disease. However, if increased sensitivity leads to poor specificity, then patients may be misdiagnosed and given inappropriate cardiac medications with potentially detrimental outcomes. In ten secondary and tertiary care hospitals across Scotland, the investigators will undertake a stepped wedge cluster randomized controlled trial of the implementation of a novel high-sensitivity troponin test. The primary end-point will be the one-year rate of cardiovascular death or recurrent myocardial infarction. This will establish whether the introduction of this high-sensitivity troponin test into routine clinical practice is beneficial to patient management and outcomes. A subset of patients will be asked to give consent for inclusion into a sub-study that will permit storage of blood samples and will require the completion of a survey during the index admission and after 6 and 12 months of follow up.
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study of niraparib as maintenance in platinum sensitive ovarian cancer patients who have either gBRCAmut or a tumor with high-grade serous histology and who have responded to their most recent chemotherapy containing a platinum agent. Niraparib is an orally active PARP inhibitor. Niraparib or placebo (in a 2:1 ratio) will be administered once daily continuously during a 28-day cycle. Health-related quality of life will be measured by the Functional Assessment of Cancer Therapy - Ovarian Symptom Index (FOSI), European Quality of Life scale, 5-Dimensions (EQ-5D), and a neuropathy questionnaire. Safety and tolerability will be assessed by clinical review of adverse events (AEs), physical examinations, electrocardiograms (ECGs), and safety laboratory values. The primary objective of this study is to evaluate efficacy of niraparib as maintenance therapy in patients who have platinum sensitive ovarian cancer as assessed by the prolongation of progression free survival (PFS).
The purpose of this study is to compare Baked Egg vs. Egg Oral Immunotherapy for inducing sustained unresponsiveness to egg exposure in children.
This study is designed to determine whether Asians who are especially sensitive to alcohol exposure can be protected by boosting their activities of an alcohol disposing enzyme. This will be accomplished by administering broccoli sprouts that are rich in an agent that increases protective enzyme activity. The test system involves applying alcohol patches to the skin and measuring skin redness.
