A pilot randomized controlled trial investigating the effects of an anti-inflammatory dietary pattern on disease activity, symptoms and microbiota profile in adults with inflammatory bowel disease.

Background/objectives: There is a lack of certainty in dietary prescription for individuals with inflammatory bowel disease (IBD) due to heterogeneity in studies to date. The aim of this study was to investigate the efficacy on disease activity of a modified anti-inflammatory dietary pattern purposely designed to reduce intake of food additives (IBD-MAID), compared to standard care, in adults with IBD.

Subject/methods: Adults with IBD were randomised to IBD-MAID (meals provided) [n = 29] or general healthy eating (GHE) [n = 29] for 8 weeks.

Assessing electronic device use behaviours in healthy adults: development and evaluation of a novel tool.

Background: Chronic exposure of the macula to blue light from electronic devices has been identified as a potential macular health concern. The impacts remain poorly investigated as no validated methods to capture usual device use behaviours exist.

Purpose: The aim of this study was to develop and validate the Electronic Device Use Questionnaire (EDUQ) against multiple 24-h electronic device use diaries in healthy Australian and United Kingdom adults.

Newly developed dietary assessment tools for lutein and zeaxanthin are correlated with 24-hour diet recalls, but are not a valid measure of intake in Australian and United Kingdom adults.

Habitual dietary intake measurement of carotenoids lutein and zeaxanthin (L/Z) has often been omitted or attempted with tools of unknown validity in past research. It was hypothesized that the dietary assessment tool, the L/Z screener, developed as part of this study, would be valid with agreement within 0.25 mg/day when compared against multiple 24-hour diet recalls in healthy Australian and United Kingdom adults.

Alterations to the duodenal microbiota are linked to gastric emptying and symptoms in functional dyspepsia.

Objective: Functional dyspepsia (FD) is a complex disorder, with debilitating epigastric symptoms. Evidence suggests alterations in gastrointestinal (GI) motility, visceral hypersensitivity, permeability and low-level immune activation in the duodenum may play a role. However, we still have a relatively poor understanding of how these factors interact to precipitate the onset of FD symptoms which are frequently meal related.
