The purpose of this study is to determine the effect of ixazomib citrate maintenance therapy on progression-free survival (PFS), compared to placebo, in participants with newly diagnosed multiple myeloma (NDMM) who have had a response (complete response [CR], very good partial response [VGPR], or partial response [PR]) to induction therapy followed by high-dose therapy (HDT) and autologous stem cell transplant (ASCT).
The purpose of this post-market observational study is to assess the effectiveness and patient perception of benefit of the ReVENT Sleep Apnea System in patients diagnosed with Obstructive Sleep Apnea due to primary tongue base closure. The ReVENT Sleep Apnea System is a minimally invasive surgical approach to treat Obstructive Sleep Apnea. The ReVENT Sleep Apnea System consists of an implanter kit and tongue implants. The implants are permanently implanted in the tongue during a minimally invasive outpatient surgical procedure to prevent tongue base closure during sleep.
Bulimia nervosa is a severe psychiatric disorder characterized by recurrent binge eating episodes followed by inappropriate compensatory behavior to prevent weight gain such as self-induced vomiting. With this project, the investigators want to investigate the role of the neurotransmitter dopamine in bulimia nervosa. Dopamine is reported to have an important influence on the neural reward system and is involved in the processing of gains and losses. The reward system is functionally connected to the individual perception of rewards in the environment. A previous study revealed that under catecholamine depletion including dopamine depletion women suffering from bulimia nervosa in their past reported mild bulimic symptoms and their reward processing became dysfunctional: their ability to use rewarding stimuli for task solving was diminished. The aim of this study is to investigate the role of reduced dopamine availability in the development or maintaining of bulimia nervosa and in the dysfunctional processing of rewarding stimuli and negative visual information. Therefore, the investigators hypothesize that catecholamine depletion achieved by oral administration of alpha-methyl-paratyrosine (AMPT) will induce mild bulimic symptoms in females suffering from bulimia nervosa in their past. In addition, they will reveal dysfunctions in reward and emotional processing under catecholamine depletion. Using functional magnetic resonance imaging, the investigators propose that a reduced activation of the nucleus accumbens, a neural structure of the reward system, will be the neural correlate of this dysfunctional reward processing. Furthermore, the amygdala, a neural structure that is involved in emotional processing, will show a higher activation under catecholamine depletion. Genetic factors additionally have an influence on the dopaminergic system. Therefore, the investigators hypothesize that genetic factors, for example the COMT val-158-met polymorphism may have an effect on the behavioral and neural response to catecholamine depletion. In sum, this investigation may help to understand which changes in reward and emotional processing may lead to a reoccurrence of bulimic symptoms. In future, the findings of this study may help to develop individual pharmacological and psychotherapeutical interventions to enhance the outcome of treatment.
Detecting serious bacterial infections (SBI) in children presenting to the Pediatric Emergency Department (PED) with fever without source (FWS) is a frequent diagnostic challenge. The recently described Lab-score, based on the combined determination of Procalcitonin, C-Reactive Protein (CRP) and urine dipstick results, has been shown an accurate tool for SBI prediction on retrospective cohorts. The investigators aimed to assess the usefulness of the Lab-score in safely decreasing unnecessary antibiotic prescriptions in children with FWS, and to prospectively determine the diagnostic characteristics of the Lab-score compared to other classically used SBI biomarkers (white blood cell (WBC) count, band count and CRP).
Bladder management has a major impact on the quality of life in patients with neurogenic bladder dysfunction. This a prospective investigation of the effects of the method for bladder evacuation on the health-related quality of life in patients with neurogenic bladder dysfunction. The changes in health-related quality of life over time (longitudinal investigation) and the differences between the different methods for bladder evacuation will be investigated. Patients will be given a standardized and validated questionnaire annually for 10 years.
Online self-help is an innovative way of providing self-help. The investigators want to study the effect of an interactive online self-help-program (Deprexis) in the treatment of severe depressive symptoms. Participants will be randomised to either twelve weeks of online-self help or a waiting-list control. Symptoms of depression and other aspects will be assessed over a six months period. The investigators hypothesise that online self-help is superior to the control condition in alleviating depressive symptoms and preventing full blown depression.
Iron deficiency (ID) with or without anaemia (IDA) is a major public health problem worldwide, especially in women of reproductive age and young children. Iron supplementation is an effective strategy to prevent and treat ID and IDA. There is a lack of data on iron bioavailability from different supplementation regimens and how to optimize bioavailability in a cost-effective and patient-friendly way. The daily supplementation with 1-4 mg Fe/kg body weight for 3 months is reported to be the most effective method to rapidly increase iron stores in subjects with ID and IDA. In IDA patients, medical practitioners often prescribe supplementation regimens with 120 mg iron per day split into 2 doses with 60 mg iron, arguing that the splitting would increase iron bioavailability compared with one single high dose. However, there is no scientific evidence for this assumption; to the contrary, results from a recent study suggest that iron bioavailability from a second supplementation dose of iron after a first supplementation dose of iron is impaired due to increased hepcidin levels. To address this bioavailability issue, the present study will determine iron absorption from 120 mg iron administered for 3 consecutive days and compare it with that from 2 doses of 60 mg iron per day administered for 3 consecutive days. The investigators hypothesize that the iron bioavailability from the single daily dose will be lower than that from the 2 doses. By measuring also hepcidin, this study will provide important insights on the iron bioavailability from a single dose of iron and on the same amount iron split into two doses (b.i.d. administration).
Prospective, multicentric, single arm post market study to gather safety and effectiveness data on the CE Marked InnFocus MicroShunt (MIDI Arrow) device in primary open angle glaucoma patients
Ferric pyrophosphate (FePP) is a water-insoluble, food grade iron compound used to fortify rice, infant cereals and chocolate-drink powders as it causes no organoleptic changes to the food vehicle. However, it is only of low absorption in man. Therefore, strategies to enhance the bioavailability of FePP, such as adding citrate or decreasing the particle size of FePP need to be investigated. The primary objectives of the present study are: 1) to test whether the presence of citrate in iron fortified rice with FePP results in higher iron bioavailability, and 2) to test whether the presence of citrate in the rice grain during the extrusion and cooking process results in higher iron bioavailability compared with iron-fortified rice where citrate has been added shortly before consumption. As a secondary objective the investigators will compare the absorption from different FePP combinations with a reference meal fortified with ferrous sulphate. The investigator hypothesize that the addition of citrate enhances iron absorption and that the positive effect is greater when the citrate is added during the extrusion. The investigator will conduct an iron absorption study in 20 women, 18 to 45 years old to evaluate the iron bioavailability from extruded rice fortified with 1) regular FePP, 2) regular FePP and citrate (both extruded into the rice kernels), 3) regular FePP and citrate added at the time of consumption, and 4) from normal rice fortified with ferrous sulphate at the time of consumption. Iron absorption will be measured as erythrocyte incorporation of stable iron isotopes at least 14 days after the administration of the isotopically labelled test meals. The iron absorption from the different meals within the same participant will be compared by repeated-measures ANOVA followed by a Bonferroni corrected pairwise comparison. The present study will provide important data where iron bioavailability from rice is accurately and directly measured using stable isotopic labels as absorption tracers. This direct data can be used to base decisions on the level of fortification, can potentially reduce costs and optimize iron delivery to the targeted population in iron fortification programs.
