Men's information-seeking behavior regarding cancer risk and screening: A meta-narrative systematic review Saab, Mohamad M.; Reidy, Mary; Hegarty, Josephine; O'Mahony, Mairin; Murphy, Mike; Von Wagner, Christian; Drummond, Frances J. Objective: Preventive strategies are known to reduce cancer risk and incidence and improve prognosis. Men seldom seek medical information about cancer prevention and risk reduction. The aim of this meta-narrative systematic review was to critically appraise evidence from qualitative, quantitative, and mixed-methods studies that explored men's information-seeking behaviors in relation to cancer prevention and risk reduction. Methods: MEDLINE, CINAHL Plus with Full Text, PsycINFO, PsycARTICLES, Psychology and Behavioral Sciences Collection, Education Full Text, and ERIC were systematically searched for studies published in English between January 1, 2006 and May 30, 2016. A total of 4117 titles were identified; of which, 31 studies were included (21 qualitative studies, 9 quantitative studies, and 1 mixed-methods study). The methodological quality of the studies was appraised by using different tools. Results: Most studies focused on screening for prostate (n = 18) and colorectal cancer (n = 7). Most men were passive information-gatherers rather than active information-seekers. Key sources of information included the Internet for active information-seekers and health care professionals for passive information-gatherers. Barriers to information-seeking included information overload, embarrassment, and fear. Low literacy and health literacy levels were addressed in 3 studies and were identified as impediments to active information-seeking. Facilitators to information-seeking included family support, media, celebrity endorsements, and targeted information. Conclusions: Men's information-seeking behavior regarding cancer risk reduction, prevention, and screening is influenced by several factors. This necessitates targeted interventions aimed at raising awareness of cancer prevention and screening, while accounting for men's informational needs, preferred learning strategies, and literacy levels.

Risk perceptions of cyber-security and precautionary behaviour

Risk perceptions of cyber-security and precautionary behaviour van Schaik, Paul; Jeske, Debora; Onibokun, Joseph; Coventry, Lynne; Jansen, Jurjen; Kusev, Petko A quantitative empirical online study examined a set of 16 security hazards on the Internet and two comparisons in 436 UK- and US students, measuring perceptions of risk and other risk dimensions. First, perceived risk was highest for identity theft, keylogger, cyber-bullying and social engineering. Second, consistent with existing theory, significant predictors of perceived risk were voluntariness, immediacy, catastrophic potential, dread, severity of consequences and control, as well as Internet experience and frequency of Internet use. Moreover, control was a significant predictor of precautionary behaviour. Methodological implications emphasise the need for non-aggregated analysis and practical implications emphasise risk communication to Internet users.

Abstract concepts and aging: An embodied and grounded perspective

Abstract concepts and aging: An embodied and grounded perspective Borghi, Anna M.; Setti, Annalisa How do we represent abstract concepts, as “justice” and “phantasy”? This issue has become hotly debated within embodied and grounded cognition views (for reviews: Pecher et al., 2011; Dove, 2016; Borghi et al., 2017). It is in fact unclear how such views can explain how we represent concepts that do not have single concrete referents and are rather detached from sensory experience (Barsalou, 2003; Binder, 2016). In spite of the increasing interest for this issue, to date evidence on abstract concepts across the lifespan is limited. Assuming that the representation of abstract concepts changes from adulthood to older age, in this paper we discuss how a new embodied and grounded proposal, the Words As social Tools (WAT) view (Borghi and Binkofski, 2014), can explain how abstract concepts are represented by older individuals. More specifically we will advance hypotheses on abstract concepts in aging focusing on WAT, and reinterpret previous findings in light of it. We propose that WAT can account for existing findings and provide a suitable framework to test conceptual knowledge in older adults

Peanut Allergen Threshold Study (PATS): Novel single-dose oral food challenge study to validate eliciting doses in children with peanut allergy

Peanut Allergen Threshold Study (PATS): Novel single-dose oral food challenge study to validate eliciting doses in children with peanut allergy Hourihane, Jonathan O'B.; Allen, Katrina J.; Shreffler, Wayne G.; Dunn Galvin, Gillian; Nordlee, Julie A.; Zurzolo, Giovanni A.; Dunn Galvin, Audrey; Gurrin, Lyle C.; Baumert, Joseph L.; Taylor, Steve L. Background: Eliciting doses (EDs) of allergenic foods can be defined by the distribution of threshold doses for subjects within a specific population. The ED05 is the dose that elicits a reaction in 5% of allergic subjects. The predicted ED05 for peanut is 1.5 mg of peanut protein (6 mg of whole peanut). Objective: We sought to validate the predicted peanut ED05 (1.5 mg) with a novel single-dose challenge. Methods: Consecutive eligible children with peanut allergy in 3 centers were prospectively invited to participate, irrespective of previous reaction severity. Predetermined criteria for objective reactions were used to identify ED05 single-dose reactors. Results: Five hundred eighteen children (mean age, 6.8 years) were eligible. No significant demographic or clinical differences were identified between 381 (74%) participants and 137 (26%) nonparticipants or between subjects recruited at each center. Three hundred seventy-eight children (206 male) completed the study. Almost half the group reported ignoring precautionary allergen labeling. Two hundred forty-five (65%) children experienced no reaction to the single dose of peanut. Sixty-seven (18%) children reported a subjective reaction without objective findings. Fifty-eight (15%) children experienced signs of a mild and transient nature that did not meet the predetermined criteria. Only 8 (2.1%; 95% CI, 0.6%-3.4%) subjects met the predetermined criteria for an objective and likely related event. No child experienced more than a mild reaction, 4 of the 8 received oral antihistamines only, and none received epinephrine. Food allergy–related quality of life improved from baseline to 1 month after challenge regardless of outcome (η2 = 0.2, P < .0001). Peanut skin prick test responses and peanut- and Ara h 2–specific IgE levels were not associated with objective reactivity to peanut ED05. Conclusion: A single administration of 1.5 mg of peanut protein elicited objective reactions in fewer than the predicted 5% of patients with peanut allergy. The novel single-dose oral food challenge appears clinically safe and patient acceptable, regardless of the outcome. It identifies the most highly dose-sensitive population with food allergy not otherwise identifiable by using routinely available peanut skin prick test responses or specific IgE levels, but this single-dose approach has not yet been validated for risk assessment of individual patients.
