Filter by:Breath analysis is a non-invasive procedure to detect and monitor diseases and it is particularly attractive for patients who have to routinely check biomarkers, such as diabetics (blood glucose) or end-stage renal disease patients (creatinine). Preliminary data in a small study with healthy subjects showed a high correlation between blood glucose levels and acetone. Therefore, the objective of this study is to correlate biomarkers (glucose level and creatinine, respectively) with the corresponding target breath components (acetone and NH3, respectively) detected by portable gas sensors in the general population and to assess possible predictive models for biomarker estimations from the corresponding target breath component and predictive models to estimate abnormal biomarker concentrations.
Daily consumption of plant sterols have been demonstrated to lower blood cholesterol. The Canadian government has recently allowed plant sterols to be added to certain foods and has also approved a disease risk reduction claim to be allowed on products containing plant sterols. However, it is unknown how Canadian consumers respond to plant sterol claims. The objective of this study was to evaluate the attitudes and understanding of different types of plant sterol claims on food labels
Oat fibre consumption has been shown to lower blood cholesterol, which is advantageous for heart health. Oat and fibre claims on food labels should help people find heart healthy food choices; however consumer attitudes and understanding of such claims are unknown. The objective of this study was to evaluate the attitudes and understanding to different types of permitted oat fibre claims.
Epidemiological, clinical and animal-experimental evidence shows a direct relationship between dietary sodium intake, blood pressure and cardiovascular event. Diverse questionnaire and 24 hour urinary sodium measurement are used to estimate sodium intake. Complete reflection of eating and cooking habits to the dietary survey method is difficult. Furthermore, the differences of database between countries make it difficult to compare the amount of sodium intake between countries. It is also difficult to consider individual variation of cooking and eating habits. Due to limitations of dietary survey method, WHO recommended 24 hour urinary sodium measurement to estimated sodium intake in the population survey, and many countries are adopting. However, in Korea National Health and Nutrition Examination Survey, only dietary survey method has been used. The present survey study was designed 1) to test the feasibility of 24 hour urinary sodium measurement for the estimation of sodium intake (including percentage of complete 24 hour urine sample collection) in the population based study; 2) to establish feasible method of 24 hour urinary sodium measurement; 3) to compare 24 hour urinary sodium measurement to the dietary survey method; and 4) to estimate the sodium intake by 24 hour urinary sodium measurement in Goyang city general population (aged 20-70 years).
Almost all rating scales for Attention-Deficit/Hyperactivity Disorder (ADHD) are not validated in France. This clearly hampers the development of the diagnosis and the monitoring of patients but also research in this domain. This study is conceived to collect data in the general population of children aged from 4 to 18 years in public schools in the city of Nice. Children are pseudo-randomly selected from classes of randomly selected schools in the city of Nice (France). Teachers fill out questionnaires using a dedicated secured website, and ask parents to fill out a similar set of questionnaires regarding their child's behaviour at home. Since ADHD has a strong genetic components, parents are also asked to fill out questionnaires regarding their own behaviour at adulthood and in childhood retrospectively. Additionally, known factors related to ADHD and other disorders as well as other putative factors are tested in the epidemiologic study.
