The Effect of Oral Processing on the Viscosity of Thickened Drinks for Patients With Dysphagia.

Objective: To determine whether a gum-containing thickener maintains its viscosity better during oral processing than a completely starch-based thickener.

Methods: Thirty-five healthy volunteers participated in a double-blind, cross-over study. Artificial tap water was thickened to honey-like consistency (effective viscosity of 1,300±100 mPa·s at a shear rate of 50 per second at 20℃) with a starch-based thickener (SB) or a gum-containing thickener (GC).

Validation of an FFQ and options for data processing using the doubly labelled water method in children.

Objective: To validate an FFQ designed to estimate energy intake in children against doubly labelled water (DLW). To investigate how quality control and standard beverage portion sizes affect the validity of the FFQ.

Design: Thirty healthy children, aged 4-6 years, participated.

Characterizing the precision of mass-spectrometry-based metabolic profiling platforms.

In conventional analytical chemistry it is customary to report figures of merit - such as precision, analysis time, limit of detection - for the chemical analysis performed. Usually, such figures of merit are reported for each analyte separately, generating a list of figures of merit. In metabolomics such a listing is not informative, since very many compounds are measured.

Randomized controlled trial assessing a traditional Chinese medicine remedy in the treatment of primary dysmenorrhea.

A proof-of-concept study to assess the safety and efficacy of a traditional Chinese medicine formula as treatment for primary dysmenorrhea showed no statistically significant benefit over placebo. However, some efficacy parameters suggested possible superiority of the active treatment and so a larger study needs to be performed to determine whether this remedy has a role in the treatment of dysmenorrhea.

Dependence of dietary intake estimates on the time frame of assessment.

Food chemical risk management needs, among other things, assessment of exposure. For dietary intake food consumption surveys are the data source to be used. One complicating factor in the usage of these data is the dependence of dietary intake estimates on the time frame of assessment.
