Moving Upstream to Prevent Child Maltreatment

Invited Commentary on Child Maltreatment Prevention - Finding Common Ground with Unintentional Injury Prevention

Setting an Agenda for Advancing Young Worker Safety in the U.S. and Canada

Scholars and practitioners from multiple perspectives, including developmental science, sociology, business, medicine, and public health, have considered the implications of employment for young people. We summarize a series of meetings designed to synthesize information from these perspectives and derive recommendations to guide research, practice, and policy with a focus on young worker safety and health. During the first three meetings, participants from the United States and Canada considered invited white papers addressing developmental issues, public health data and findings, as well as programmatic advances and evaluation needs. At the final meeting, the participants recommended both research and policy directions to advance understanding and improve young worker safety

Storage of poisonous substances and firearms in homes with young children visitors and older adults

Most unintentional childhood poisonings and firearm injuries occur in residential environments. Therefore, a preventive strategy includes limiting children’s access to poisons and firearms through safe storage. This study examines storage of poisons and firearms among households with older adults, and households where young children reside compared to those where they visit only

Risk and protective factors for fires, burns, and carbon monoxide poisoning in U.S. households

More needs to be known about the prevalence of risk and protective factors for fires, burns, and carbon monoxide poisoning in U.S. households

Evaluating implementation of a fire-prevention injury prevention briefing in children's centres: cluster randomised controlled trial

Background: Many developed countries have high mortality rates for fire-related deaths in children aged 0–14 years with steep social gradients. Evidence-based interventions to promote fire safety practices exist, but the impact of implementing a range of these interventions in children’s services has not been assessed. We developed an Injury Prevention Briefing (IPB), which brought together evidence about effective fire safety interventions and good practice in delivering interventions; plus training and facilitation to support its use and evaluated its implementation. Methods: We conducted a cluster randomised controlled trial, with integrated qualitative and cost-effectiveness nested studies, across four study sites in England involving children’s centres in disadvantaged areas; participants were staff and families attending those centres. Centres were stratified by study site and randomised within strata to one of three arms: IPB plus facilitation (IPB+), IPB only, usual care. IPB+ centres received initial training and facilitation at months 1, 3, and 8. Baseline data from children’s centres were collected between August 2011 and January 2012 and follow-up data were collected between June 2012 and June 2013. Parent baseline data were collected between January 2012 and May 2012 and follow-up data between May 2013 and September 2013. Data comprised baseline and 12 month parent- and staff-completed questionnaires, facilitation contact data, activity logs and staff interviews. The primary outcome was whether families had a plan for escaping from a house fire. Treatment arms were compared using multilevel models to account for clustering by children’s centre. Results: 1112 parents at 36 children’s centres participated. There was no significant effect of the intervention on families’ possession of plans for escaping from a house fire (adjusted odds ratio (AOR) IPB only vs. usual care: 0.93, 95%CI 0.58, 1.49; AOR IPB+ vs. usual care 1.41, 95%CI 0.91, 2.20). However, significantly more families in the intervention arms reported more behaviours for escaping from house fires (AOR IPB only vs. usual care: 2.56, 95%CI 01.38, 4.76; AOR IPB+ vs. usual care 1.78, 95%CI 1.01, 3.15). Conclusion: Our study demonstrated that children’s centres can deliver an injury prevention intervention to families in disadvantaged communities and achieve changes in home safety behaviours

Reduced conditioned fear response in mice that lack Dlx1 and show subtype-specific loss of interneurons

The inhibitory GABAergic system has been implicated in multiple neuropsychiatric diseases such as schizophrenia and autism. The Dlx homeobox transcription factor family is essential for development and function of GABAergic interneurons. Mice lacking the Dlx1 gene have postnatal subtype-specific loss of interneurons and reduced IPSCs in their cortex and hippocampus. To ascertain consequences of these changes in the GABAergic system, we performed a battery of behavioral assays on the Dlx1 mutant mice, including zero maze, open field, locomotor activity, food intake, rotarod, tail suspension, fear conditioning assays (context and trace), prepulse inhibition, and working memory related tasks (spontaneous alteration task and spatial working memory task). Dlx1 mutant mice displayed elevated activity levels in open field, locomotor activity, and tail suspension tests. These mice also showed deficits in contextual and trace fear conditioning, and possibly in prepulse inhibition. Their learning deficits were not global, as the mutant mice did not differ from the wild-type controls in tests of working memory. Our findings demonstrate a critical role for the Dlx1 gene, and likely the subclasses of interneurons that are affected by the lack of this gene, in behavioral inhibition and associative fear learning. These observations support the involvement of particular components of the GABAergic system in specific behavioral phenotypes related to complex neuropsychiatric diseases

Preventing injuries by understanding energy damage

This section looks back on a ground-breaking contribution to public health and provides a commentary on its significance from a modern perspective. To complement the theme of this month’s issue, Carol W Runyan and Susan P Baker review a paper by William Haddon that was published in the Journal of Trauma in 1973

What drives publishing productivity for pre-tenure marketing faculty:insights using the lens of resource advantage theory

The promotion, tenure and salary of marketing faculty have been topics of intense interest recently. What has received less interest are the drivers of publishing productivity, especially for new, pre-tenure faculty. We use resource-advantage (RA) theory to examine the drivers of pre-tenure faculty productivity, specifically in the top marketing journals. Positive predictors of productivity, and thus key faculty resources are: degree-granting department ranking, advisor productivity and length of time in the new job. As would be predicted by RA theory, number of methods courses in a doctoral program has no effect on publishing
