Filter by:Workers in the salmon industry are at risk of developing allergies and respiratory diseases, including asthma, due to occupational exposure to bioaerosols, i.e. biological agents such as allergens, enzymes and endotoxins, in their work environment. The overall objective of this intervention trial is to identify effective and feasible control measures (interventions) that reduce exposure to these bioaerosols. The project comprises nine salmon processing factories in northern, central and western Norway. The factories are allocated to either one of the two intervention arms or the control group. In all factories, an assessment of exposure to bioaerosols will be performed. In addition, employees will be invited to undergo a health examination and fill out a self-administered questionnaire including information on demographics, work tasks, health and health promoting factors. The intervention trial is part of a broader study that comprises several substudies including the identification of clinically relevant allergens, investigation of exposure-response relationship between the exposure to individual bioactive agents in bioaerosols and investigations of prevalence of airway symptoms, altered lung function, skin symptoms or immunological responses indicating hypersensitivity. Finally the project includes the identification of health promoting factors that are present in the salmon processing industry. The project is an interdisciplinary multi-center study that places great emphasis on a close dialogue between the researchers and industry in all phases of the project.
Current treatments for patients with drug reaction with eosinophilia and systemic symptoms (DRESS) include supportive care, steroids and cyclosporine. No randomized controlled trial (RCT) exists in comparing these treatments and all available literature comes in the form of case reports and case series. These two treatments are considered standard of care and this trial seeks only to compare outcomes of DRESS between these two therapies. No additional labs, therapies or procedures will be used apart from those that are routinely done for patients with this diagnosis. This will be a pilot study to determine efficacy of the two therapies with particular endpoints in mind so that the investigators can study the safety of these two therapies in patients with DRESS. Data suggests a potential benefit for adults with DRESS using either steroids or cyclosporine but the investigators are seeking a comparison of efficacy of these two therapies. The study population will include adults with a Registry of Severe Cutaneous Adverse Reaction (RegiSCAR) score of greater than 4 (i.e. a likely diagnosis of DRESS). The investigators will exclude patients with sepsis, active Hepatitis B or C, active tuberculosis, a documented allergy to steroids or cyclosporine, and patients with an estimated glomerular filtration rate (eGFR) < 30 (unless on dialysis in which case the participants will be included).
Education and dietary support are integral in managing food allergy in children. The study aim is to analyze the impact of E-learning on parental confidence in managing their child's food allergy.
Background: Functional somatic disorders (FSD) are frequent in all medical settings and characterized by persistent physical symptoms that cannot be explained by other somatic or psychiatric conditions. In recent decades, a number of different types of functional somatic disorders have been defined, but so far there is no clear explanation for the pathophysiology. The high prevalence of olfactory problems in some patients with FSD suggests that olfactory symptoms are a potential diagnostic biomarker, especially in patients with multiple chemical sensitivity (MCS). The olfactory system is a unique sense with direct pathways to the limbic system, which is associated with emotion and mood. The focus on the olfactory system has revealed a significant association of this sense with numerous diseases. Hypotheses: - Patients with MCS and FSD have normal olfactory tests (normosmic subjects according to TDI score using "sniffing test") but differ in habituation test compared to healthy controls. - MCS and FSD patients have different odour perception processing in the brain as a "fingerprint" of functional somatic disorder compared to healthy controls. Research plan: The aim of this parts of the study is to identify specific MRI and paraclinical measures for MCS and BDS. In the first phase, 5 patients with MCS and 5 healthy controls will have a full clinical test of the olfactory system at the Flavour Institute, AU. In addition, they will be scanned (for "fingerprinting") where the investigators expect to find changes in olfactory connectivity similar to those seen in depression. This phase of the study will lead to a conclusion on the exact MR parameters to be used in the main study. In the second phase of the study, 10 patients with MCS, 10 with FSD, and 10 healthy controls will be evaluated using a test battery of questionnaires and paraclinical tests. Perspectives: Previous imaging studies have focused on pain stimulation paradigms, rest-state fMRI, and DTI, but the olfactory system may be the "missing link" in identifiying a quantitative candidate in terms of whole-brain computational modeling and could potentially be used as a "fingerprint" in diagnosis and treatment monitoring.
Data and specimens will be collected longitudinally from patients seen in the UVA Interstitial Lung Disease (ILD) clinic in order to describe the phenotypic expression of various interstitial lung diseases. Samples will also be collected from a control group for comparison purposes. All data will be entered into a repository for future research purposes or screening for new studies that become available. This data will help identify trends and hopefully lead to a better understanding of the disease progression, treatment options, and outcomes.
The research aims to elucidate a specially-designed personalized diet based on Traditional Asian Diet and its efficacy in increasing the gut colonization of Prevotella sp. and butyrate levels in pregnant mothers and the benefits in reducing infant's food allergy development.
The primary objective of this study is to test the diagnostic sensitivity of antibody tests for the diagnosis of SARS-CoV2 infection, available to clinical laboratories, within a national network of hospitals carrying out research activities. Test the diagnostic specificity of antibody tests for the diagnosis of SARS-CoV2 infection. Complete a systematic evaluation of the different approaches. Perform Health technology Assessment (HITA) of the methodologies under study, in order to verify their reliability to the immunoglobulin levels produced by each individual exposed patient.
In a population based on healthy adolescents we will conduct a double blind placebo controlled food challenge (DBPCFC) with cross-over to identify patients with NCGS as recommended by the socalled Salerno criteria. It will take place at Hans Christian Andersen Childrens Hospital at Odense University Hospital, Denmark in October-November 2020.
iREACH is a five-year NIH funded study aimed at assessing and improving pediatric clinician adherence to the 2017 NIAID Prevention of Peanut Allergy (PPA) Guidelines. iREACH has been developed as an electronic health record (EHR) integrated Clinical Decision Support (CDS) tool together with educational modules on the PPA guidelines to assist clinicians in implementing the 2017 NIAID PPA Guidelines. A practice-based, two-arm, cluster-randomized clinical trial will evaluate the effectiveness of iREACH in increasing pediatric clinician adherence to the PPA Guidelines and explore the end-goal of reducing peanut allergy incidence by age 2.5 years in the intervention vs control group. This study has the potential to: 1) provide evidence regarding the effectiveness of iREACH in promoting clinical processes and outcomes related to the PPA Guidelines, 2) provide important insight about practice-based implementation of PPA Guidelines by pediatric clinicians, allergists and caregivers, and 3) facilitate rapid, widespread implementation of PPA Guidelines and reduce peanut allergy incidence across the US.
This study is phase II, open label, clinical trial to determine the efficacy of Olaparib maintenance with Bevacizumab and Pembrolizumab by assessment progression-free survival(6 months PFS rate) in BRCA non-mutated patients with platinum-sensitive recurrent ovarian cancer.
