Filter by:To confirm the protein expression level in radiation-induced late effects patients and to determine the performance value, in particular the positive predictive value, of a blood test based on the dosage of a panel of five proteins, it is necessary to validate these preliminary results by a prospective study on a large cohort of patients.
The Nutrition Study of the GA2LEN Follow-Survey was designed to investigate the association between usual dietary intake and allergic and respiratory outcomes in adults across Europe. Within this framework, a food frequency questionnaire (FFQ) was designed to ascertain usual dietary intake of 250 food items, which was translated into the languages of the participant centres. Information on daily intake of foods, nutrients, and flavonoids was derived.
Double blind parallel study to measure the efficacy of a toothpaste containing calcium-silicate/phosphate on dentinal hypersensitivity compared to a control toothpaste containing fluoride
To investigate the efficacy of an experimental oral rinse, containing 1.5% potassium oxalate (KOX) and 0 parts per million (ppm) fluoride in relieving dentine hypersensitivity (DH) after 8 weeks use compared with a placebo oral rinse and a commercialized fluoride oral rinse.
The present study was designed as a randomised controlled clinical trial which was unicenter, double-blinded, parallel designed study, according to the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010. The study period was from July 2014 to September 2015.
The purpose of this study is to evaluate the clinical usefulness of assessing specific human allergy antibodies and other immunologic parameters associated with the diagnosis, evolution, and management of allergic disease.
This study is to evaluate the benefit and tolerability of a Mouthrinse (IQP-OLP-101) in the treatment of dentine hypersensitivity.
BACKGROUND & AIMS: Bowel hypersensitivity (lower threshold for discomfort in response to distention of a balloon in the rectum compared to healthy controls) is a key documented feature in Irritable Bowel Syndrome (IBS) mechanistic studies. The use of the barostat catheter to assess bowel hypersensitivity has been well documented in research settings, but it's use is time consuming which makes it unpractical for routine clinical practice (test time up to 60 minutes). The Rapid Barostat Bag is a novel device used to obtain a rapid and simple assessment of the rectal function, which has received approval for use by Health Canada. Although its safety and use has been validated in healthy controls, RBB use has never been reported in a cohort of IBS patients. The aim of this study is to 1) evaluate bowel sensitivity in IBS patients, compared with healthy controls and 2) determine whether the sensory threshold predicts response to standard of care interventions such as diet or medications. METHODS: This is a prospective controlled study. All participants will undergo RBB testing and will answer a questionnaire related to bowel symptoms (IBS-SSS - IBS Severity Scoring System) and a questionnaire related to anxiety/depression (HADS - Hospital and Anxiety and Depression Scale). HYPOTHESIS: The investigators hypothesize that IBS patients will display lower bowel sensitivity thresholds than healthy controls, using the RBB device. Furthermore, we predict that those with a low sensory threshold (i.e. visceral hypersensitivity) are most likely to respond to interventions that decrease bowel distention (e.g. low FODMAP diet) or the medication linaclotide that is reported to decrease pain signaling.
This is a pilot study that provides the investigators with an opportunity to assess the application of PSM technology for patient monitoring in the NICU. This is a prospective, observational, cohort study.The investigators expect the duration of infant participation in this study to be 6 hours per single recording session with no follow-up required.
This is a bilateral, non-dispensing, randomized, cross-over, single-masked study. There are a total of 3 visits where all study endpoints will be measured in all subjects at baseline with habitual lenses and under the two testing treatments sequentially in separate visits based on the randomization scheme
