Item Association between recruitment methods and attrition in Internet-based studies.(PUBLIC LIBRARY SCIENCE, 2014) Bajardi P; Paolotti D; Vespignani A; Eames K; Funk S; Edmunds WJ; Turbelin C; Debin M; Colizza V; Smallenburg R; Koppeschaar C; Franco AO; Faustino V; Carnahan A; Rehn M; Merletti F; Douwes J; Firestone R; Richiardi LInternet-based systems for epidemiological studies have advantages over traditional approaches as they can potentially recruit and monitor a wider range of individuals in a relatively inexpensive fashion. We studied the association between communication strategies used for recruitment (offline, online, face-to-face) and follow-up participation in nine Internet-based cohorts: the Influenzanet network of platforms for influenza surveillance which includes seven cohorts in seven different European countries, the Italian birth cohort Ninfea and the New Zealand birth cohort ELF. Follow-up participation varied from 43% to 89% depending on the cohort. Although there were heterogeneities among studies, participants who became aware of the study through an online communication campaign compared with those through traditional offline media seemed to have a lower follow-up participation in 8 out of 9 cohorts. There were no clear differences in participation between participants enrolled face-to-face and those enrolled through other offline strategies. An Internet-based campaign for Internet-based epidemiological studies seems to be less effective than an offline one in enrolling volunteers who keep participating in follow-up questionnaires. This suggests that even for Internet-based epidemiological studies an offline enrollment campaign would be helpful in order to achieve a higher participation proportion and limit the cohort attrition.Item Item The relationship between driving anxiety and driving skill: A review of human factors and anxiety-performance theories to clarify future research needs(New Zealand Psychological Society, 2008) Taylor JE; Deane FP; Podd JThis article examines theory and identifies gaps in research related to the role of driving skills in driving anxiety. Increasingly, investigators have examined the clinical features of driving anxiety and the more severe situation of driving fear and phobia, but the possible involvement of driving skills has been neglected. This is surprising given the potential implications for skills training and remediation in the assessment and treatment of some of those who experience driving anxiety, fear, and phobia. The largest body of relevant research comes from the driving and human factors literature on the relationship between anxiety and driving performance. The main theories addressing the relationship between anxiety and performance are examined, with specific attention to studies that have applied theoretical models to the driving situation. The paper identifies the need for further research regarding the relationship between driving skills and performance for individuals reporting driving anxiety. The implications for assessment and treatment are outlined, such as the role of driving task characteristics in planning exposure therapy.Item A standardised static in vitro digestion method suitable for food - an international consensus(Royal Society of Chemistry, 7/04/2014) Minekus M; Alminger M; Alvito P; Ballance S; Bohn T; Bourlieu C; Carriere F; Boutrou R; Corredig M; Dupont D; Dufour C; Egger L; Golding M; Karakaya S; Kirkhus B; Le Feunteun S; Lesmes U; Macierzanka A; Mackie A; Marze S; McClements DJ; Menard O; Recio I; Santos CN; Singh RP; Vegarud GE; Wickham MSJ; Weitschies W; Brodkorb ASimulated gastro-intestinal digestion is widely employed in many fields of food and nutritional sciences, as conducting human trials are often costly, resource intensive, and ethically disputable. As a consequence, in vitro alternatives that determine endpoints such as the bioaccessibility of nutrients and non-nutrients or the digestibility of macronutrients (e.g. lipids, proteins and carbohydrates) are used for screening and building new hypotheses. Various digestion models have been proposed, often impeding the possibility to compare results across research teams. For example, a large variety of enzymes from different sources such as of porcine, rabbit or human origin have been used, differing in their activity and characterization. Differences in pH, mineral type, ionic strength and digestion time, which alter enzyme activity and other phenomena, may also considerably alter results. Other parameters such as the presence of phospholipids, individual enzymes such as gastric lipase and digestive emulsifiers vs. their mixtures (e.g. pancreatin and bile salts), and the ratio of food bolus to digestive fluids, have also been discussed at length. In the present consensus paper, within the COST Infogest network, we propose a general standardised and practical static digestion method based on physiologically relevant conditions that can be applied for various endpoints, which may be amended to accommodate further specific requirements. A frameset of parameters including the oral, gastric and small intestinal digestion are outlined and their relevance discussed in relation to available in vivo data and enzymes. This consensus paper will give a detailed protocol and a line-by-line, guidance, recommendations and justifications but also limitation of the proposed model. This harmonised static, in vitro digestion method for food should aid the production of more comparable data in the future.
