Filter by:Food allergy affects 1 in 30 children, and is the commonest trigger for life-threatening reactions (anaphylaxis) in this age group. It is a major public health issue, with practical implications for industry, education and healthcare systems. Oral immunotherapy (OIT) is an emerging treatment option, where small, increasing doses of a food allergen are used to cause "desensitisation", so food-allergic individuals no longer have symptoms when exposed to the trigger food. However, frequent allergic reactions during OIT (including anaphylaxis) are common, and can lead to patients having to stop treatment. In addition, food-allergic children usually dislike the taste of the food they are allergic too, which affects compliance and treatment success. There is a lack of longer-term data to inform cost-effectiveness analyses for OIT. The NATASHA study will recruit young people from age 6+ years with IgE-mediated peanut allergy, and young people aged 3+ years with IgE-mediated allergy to cow's milk, who will undergo oral immunotherapy for these allergens using real-world foods (taken carefully according to a standardised protocol under medical supervision). In addition to assessing efficacy and safety outcomes, we will also collect longer-term data to evaluate cost-effectiveness in the UK setting.
The investigators designed a prospective, 2-armed, cluster-randomized multicenter clinical trial on the effect of a by a digital application triggered intervention on quality of life and therapy-adherence among breast cancer patients, compared to standard of care.
This study will investigate the efficacy of three diode laser wavelengths 445 nm, 660 nm, 970 nm when applied just before placement of composite restoration on reducing postoperative sensitivity from Non-carious cervical lesions (NCCLs) with class V cavity preparation.
This pilot study trial will test the acceptability, feasibility, and usability of a brief enhanced anxiety sensitivity treatment to reduce anxiety sensitivity and functional impairment in Veterans.
Sensitive skin is a subjective cutaneous hyper-reactivity to environmental factors. People report exaggerated reactions when their skin, especially on the face, is in contact with substances such as cosmetics. For this reason, Toleriane Ultra has been developed to limit the risk of allergy and relieve skin discomfort. The study aims at demonstrating that Toleriane Ultra is well tolerated in participants with allergic background and having experienced former intolerance to their cosmetic or toiletries routine, and improves skin sensitivity in such individuals. This open-labeled, multicenter study was conducted under dermatological control in Caucasian subjects above 16 years of age with an allergic background and intolerance to cosmetics lasting for at least 2 years prior to inclusion. The dermocosmetic product was to be applied on the entire face twice daily for 28 days.
This clinical trial was conducted to compare the desensitizing effect of toothpaste containing the active ingredient of an extract of Galla chinensis and toothpaste containing fluoride in patients with dentin hypersensitivity.
The ability of the brain to sense changing sodium levels in the blood is critical in mediating the neurohumoral responses to hypernatremia, however, the mechanisms underlying sodium sensing in humans is poorly understood. The purpose of this study is to identify key sodium-sensing regions of the human brain in older adults and determine if the Na-K-2Cl co-transporter mediates the neurohumoral response to acute hypernatremia. Completion of this project will increase our understanding of blood pressure regulation, which has major public health implications.
This phase I clinical trial is designed to evaluate the safety and tolerability of VLP Peanut in healthy subjects and in subjects with peanut allergy (PA). This clinical trial will evaluate the immunotoxicity profile of VLP Peanut in healthy subjects and assess the immunotoxicity profile and the degree of reactogenicity (allergenicity) in subjects with PA. This clinical trial will also explore preliminary proof of efficacy of VLP Peanut in subjects with PA.
Due to the impracticality of accessing the gold standard test devices, researchers have developed easy-to-use and cost-effective smartphone applications that do not require expert knowledge, and these applications have been used to measure different motor abilities. Smartphone applications such as CODtimer, Stopwatch Movie watch, and Seconds Count are used to evaluate the ability to change direction within these biomotor features. However, the validity and reliability of these applications are the subjects of research.
Thirst is a perception that provokes the desire to drink liquids. It is a multidimensional symptom that is described in terms of intensity and distress and is associated with dry mouth, called xerostomia. Thirst is poorly recognized in intensive care unit practice. Yet, research has shown that it is one of the most prevalent, most intense, and least well treated symptoms in intensive care patients. Thirst and dry mouth are associated with physical discomfort in the ICU. However, thirst often goes unnoticed and untreated. In this context, The investigators aim to conduct a prospective observational study in mechanically ventilated patients able to communicate to better understand the prevalence, intensity, mechanisms and prognostic value of thirst as well as dry mouth sensation. Primary objective: to assess thirst in mechanically ventilated patients. Primary endpoint: visual analog thirst scale from 0 mm (no thirst) to 100 mm (maximal thirst) 1. Patient 18 years of age and older 2. Patients undergoing invasive mechanical ventilation for at least 24 hours at one of the participating centers 3. No objection to participation in the study During the study period, patients from 3 resuscitation sites are systematically screened for inclusion in the study on a daily basis, between 9:00 am and 12:00 pm. Subjects meeting the inclusion and non-inclusion criteria (with the exception of the delirium test) will be informed of the study by the principal investigator or any other investigator trained and declared in the research. The oral information will be completed by the delivery of an information note. Patients who wish to participate in the study will be given up to 24 hours to consider their decision. If the patient agrees to participate in the study, his or her non-opposition is collected by the investigator on a dedicated form in duplicate. One copy will be given to the patient, and the other will be kept in the department with the research documents. In case of suspected confusion, a delirium screening test (CAM-ICU) will be performed to verify the patient's eligibility. If the test confirms the presence of confusion, the patient will be excluded from the study. The information and the collection of the non-opposition will be notified in the patient's medical file. Following their inclusion, patients are assessed only once during their stay in the ICU: the day of inclusion. Once enrolled, patients are asked to rate the intensity of thirst by placing a cursor on a 100 mm visual analog scale (VAS) bounded on the left by "not thirsty" and on the right by "intolerably thirsty". If a patient understands the principle of the assessment but is unable to move the VAS cursor himself, the observer assists the patient by holding the scale and supporting the patient's forearm. If the subject is unable to move his or her arms (as in some cases of severe neuromuscular impairment), observers are allowed to manipulate the VAS slider following the patient's instructions. However, this is not recommended and should be avoided whenever possible. The slider should never be adjusted directly or solely by the investigator. The visual analog scales for dry mouth, anxiety, pain and dyspnea will be performed as part of the protocol after the thirst assessment. The oral status, the search for edema or skin folds and the Revised Oral Assessment Guide (ROAG) score for intubated patients will also be performed at the same time. An average of 20 minutes is necessary to perform all these procedures.
