Dutch patients, caregivers and healthcare professionals generate first nationwide research agenda for juvenile idiopathic arthritis.

BACKGROUND: Involving the end-users of scientific research (patients, carers and clinicians) in setting research priorities is important to formulate research questions that truly make a difference and are in tune with the needs of patients. We therefore aimed to generate a national research agenda for Juvenile Idiopathic Arthritis (JIA) together with patients, their caregivers and healthcare professionals through conducting a nationwide survey among these stakeholders. METHODS: The James Lind Alliance method was used, tailored with additional focus groups held to involve younger patients. First, research questions were gathered through an online and hardcopy survey. The received questions that were in scope were summarised and a literature search was performed to verify that questions were unanswered. Questions were ranked in the interim survey, and the final top 10 was chosen during a prioritisation workshop. RESULTS: Two hundred and seventy-eight respondents submitted 604 questions, of which 519 were in scope. Of these 604 questions, 81 were generated in the focus groups with younger children. The questions were summarised into 53 summary questions. An evidence checking process verified that all questions were unanswered. A total of 303 respondents prioritised the questions in the interim survey. Focus groups with children generated a top 5 of their most important questions. Combining this top 5 with the top 10s of patients, carers, and clinicians led to a top 21. Out of these, the top 10 research priorities were chosen during a final workshop. Research into pain and fatigue, personalised treatment strategies and aetiology were ranked high in the Top 10. CONCLUSIONS: Through this study, the top 10 research priorities for JIA of patients, their caregivers and clinicians were identified to inform researchers and research funders of the research topics that matter most to them. The top priority involves the treatment and mechanisms behind persisting pain and fatigue when the disease is in remission.

Selection and evaluation of adsorbents for the removal of anionic surfactants from laundry rinsing water.

Low-cost adsorbents were tested to remove anionic surfactants from laundry rinsing water to allow re-use of water. Adsorbents were selected corresponding to the different surfactant adsorption mechanisms. Equilibrium adsorption studies of linear alkyl benzene sulfonate (LAS) show that ionic interaction results in a high maximum adsorption capacity on positively charged adsorbents of 0.6-1.7 gLAS/g. Non-ionic interactions, such as hydrophobic interactions of LAS with non-ionic resins or activated carbons, result in a lower adsorption capacity of 0.02-0.6 gLAS/g. Negatively charged materials, such as cation exchange resins or bentonite clay, have negligible adsorption capacities for LAS. Similar results are obtained for alpha olefin sulfonate (AOS). Cost comparison of different adsorbents shows that an inorganic anion exchange material (layered double hydroxide) and activated carbons are the most cost-effective materials in terms of the amount of surfactant adsorbed per dollar worth of adsorbent.
