Filter by:The use of titanium dental implants has become a common modern treatment to restore teeth. Although the success rate of dental implants is high, inflammation around the dental implant still occurs. The current study will investigate if the inflammation around the implant is due to bacterial infection, hypersensitivity or both. The goal of this cross-sectional study is to (1) Establish the levels of cytokines in peri-implant crevicular fluid associated with bacterial infection and hypersensitivity reaction; (2) Compare the levels of cytokines associated with hypersensitivity and bacterial infection between healthy implants and inflamed implants (peri-mucositis and peri-implantitis); (3) Determine whether the difference in the levels of cytokines, if they exist, reflects the clinical diagnosis of healthy implants and inflamed implants.
Food allergy is an immune reaction, triggered by food protein allergens, of varying severity, from mild local reaction to life threatening anaphylaxis and fatalities. Peanut is a plant from the botanical family of the Fabaceae, more commonly known as legumes. The prevalence of peanut and tree nut allergy is increasing. In France (ELFE cohort), it is estimated to 0.93%. The tree nuts include mainly almond, hazelnut, pistachio, cashew nut, walnut, pecan nut and Brazil nut. Allergy's prevalence is estimated to 0.54% in children up to 5.5 years. Peanut allergy is a main cause of anaphylaxis and deaths due to food allergy. Recurrence of food allergy is a main concern. The risk has been estimated to 10% per year for peanut. In France, Data in real-life on the rate of recurrence of allergic reactions and anaphylaxis to peanut/tree-nut as well as risk factors, are lacking. The objective of this study is to assess the frequency of allergic reaction to peanut and tree-nuts, to describe the reactions' characteristics and risk factors.
The study will only involve identification of the listed allergies from the electronic medical record and investigation into the symptoms that prompted this allergy listing. The purpose is to evaluate demographics and prevalence of allergies in patients presenting for surgery, evaluate the medical decision making process behind allergy identification, and determine its potential impact on perioperative care. The participants will be asked to complete a survey in REDCap using an iPad during the visit.
To investigate whether sildenafil (phosphodiesterase 5 inhibitor) induces migraine-like headache in people with persistent post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI).
Peanut and nut allergy can be life threatening. Some patients have very low threshold levels (i.e. the amounts of peanut and nuts to which the patients react), others react to higher doses. The reasons for these differences in threshold are not well understood. Patients with peanut and nut allergy often suffer from other allergic diseases (atopic dermatitis, hay fever and asthma). A disturbed gut microbiota composition and an increased gut permeability may explain the development of allergic disease. We hypothesize that increased gut permeability is related to low threshold levels to peanuts or nuts. In addition, as it is known that nutrition can influence our gut permeability, we also hypothesize that a healthful immune-supportive diet restores gut permeability and alleviates symptoms. Therefore, the purpose of the study is to study in peanut and nut allergic children: 1. the relationship between gut permeability and threshold levels to peanut or nuts; 2. the effect of an immune-supportive diet on gut permeability, gut microbiome composition, coexisting allergic symptoms and quality of life
The aim of the study is to assess the prevalence of peanut, tree nuts, and sesame allergy in Polish children at high risk of food allergy. Additionally, the timing of the development of peanut, tree nuts and sesame allergy in the first three years of life in a high-risk population will be assessed.
This study investigates whether spores from birch rust fungi (Melampsoridium Betulinum = MB) may be the eliciting allergen in patients with seasonal airway allergy during autumn in North Norway. Patients with suspected allergy to MB are compared with non-allergic controls using data about allergic disease and daily allergic symptoms during autumn. Potential variations in allergic symptoms during season will be compared with spread of MB spores. Sensitation to MB and MB allergy are to be tested with skin prick test (SPT), measurements of spesific immunglobulin E (IgE) in serum, passive basophil activation test (pBAT) and nasal provocation test (NPT)
Cureety is a digital telemonitoring platform specifically designed to monitor cancer patients through self-reporting of adverse events, accompany patients and their medical teams and complement existing healthcare practices. The platform aims to detect signs and symptoms of health deterioration and disease progression, allowing the medical team to intervene earlier than usual compared to conventional care. The patients are asked to respond to an electronic patient-reported outcome (ePRO) questionnaire. The digital tool is configured for each patient that generates specific questions that allow grading of adverse events relevant to their specific treatment and disease profile. At the core of the platform is the medical device "Cureety TechCare", an algorithm that outputs a "clinical classification" based on the adverse events reported by the patients. There are four levels that correspond to the patients' health states, either "critical" ("red"), "to be monitored" ("orange"), "compromised" ("yellow"), or "correct" ("green"). In the case of a red or orange classification, the patients are asked to contact their medical team. In addition, the medical team can monitor the patient classifications from a distance including receiving notifications when patients are classified red and orange. The present study was designed to retrospectively evaluate the performance of the "Cureety TechCare" medical device in real-life using data collected in the Cureety database.
Italian multicenter study, will enroll ~566 pts with oligometastatic hormone sensitive prostate cancer who are candidates to receive treatment with apalutamide. After 6 months from the start of treatment, patients will be randomized to receive local treatment based on the investigator's choice ( either one between primary radiotherapy or cytoreductive prostatectomy), in addition to apalutamide, or to continue just with medical therapy.
The study will systematically evaluate how an emergency manual-a collection of checklists and fact sheets-affects the performance of resuscitation teams during the management of priority one patients in an emergency department.
