Supporting direct support professionals in enabling people with intellectual disabilities to engage in meaningful activities: protocol for the Meaningful Activities 4 All (MA4A) study based on the human-centred design process.

INTRODUCTION: Meaningful activities (MA) have a positive impact on identity, well-being, participation and inclusion. Although people with intellectual disabilities (PID) depend on their direct support professionals (DSPs) to engage in MA, the DSPs need support which could enable them to offer more qualitative care and support. METHODS AND ANALYSIS: To identify DSPs' needs, and to develop a tool/service, an innovative and iterative approach is developed, based on the human-centred design (HCD) process, combined with traditional qualitative and quantitative research methods. In the inspiration phase (needs analysis), in-depth interviews will be conducted in two day care centres in Flanders using an interpretative phenomenological analyses, one with a supply-driven approach and the other with a demand-driven approach, followed by a survey sent to all Flemish day care centres. In the ideation phase, the insights of phase 1 will guide a cocreation process (comprising a World Cafe, brainstorm and prototype sessions) with the DSPs, PID and other stakeholders. In the implementation phase, the solution will be tested in the two day care centres from phase 1 by means of living labs and a realist evaluation. By adopting this protocol, the functionality, quality, usability and acceptance are expected to increase. This protocol adopts all phases of the HCD process and shows the complementarity of HCD with traditional research methods. PID and the DSPs will benefit as the end result is truly grounded in their specific needs and wishes. ETHICS AND DISSEMINATION: Ethical approval by the Ethics Committee of the University Hospital Ghent, Belgium (reference numbers: B670202042983 and PA2021-091). All participants will sign informed consent forms. Results of this study will be submitted for publication in relevant peer-reviewed journals and will be presented at relevant conferences.

Metabolism of ferulic acid during growth of Lactobacillus plantarum and Lactobacillus collinoides.

BACKGROUND: Food-isolated lactic acid bacteria can transform ferulic acid (FA) into several products. Since quantification of these metabolites during the different bacterial growth phases is lacking, the aim of this study was to identify and quantify conversion products of FA and to follow the kinetics of FA metabolism during growth of Lactobacillus plantarum and Lactobacillus collinoides. RESULTS: Lactobacillus plantarum and Lactobacillus collinoides were incubated in MRS broth, to which different amounts of FA were added (final concentrations of 0, 0.5, 1.5 and 3 mmol L⁻¹), at 30 °C until the late stationary phase. Lactobacillus plantarum metabolised FA into 4-vinylguaiacol (4-VG) and hydroferulic acid (HFA). Conversion to 4-VG started simultaneously with the degradation of FA, while formation of HFA started in the mid-exponential phase. Lactobacillus collinoides only formed 4-VG, mainly in the stationary phase. No significant effect of the different amounts of FA was seen on the growth and fermentation characteristics of both bacteria. CONCLUSION: The results demonstrate that both bacteria are able to convert FA. However, start of conversion differs between the two strains. The different amounts of FA had no influence on the growth and fermentation characteristics of both bacteria.
