Background: There is growing evidence to support the introduction of pre-conception interventions to optimise the health of mothers and their future children. At present, there is poor awareness regarding the importance of pre-conception care (PCC) amongst healthcare professionals and couples planning a pregnancy. Community pharmacies are ideally placed to reach a range of prospective couples planning a pregnancy and could effectively provide information about PCC.

Objective: Marginalised populations are less likely to take part in health research, and are sometimes considered 'easy to ignore'. We aimed to describe our approach and results of recruiting parents who experience disadvantage, for focus groups exploring infant feeding on the island of Ireland. Upon receiving ethical approval, we implemented recruitment strategies that included building rapport with community organisations through existing networks, targeting specific organisations with information about our aims, and utilising social media groups for parents.

Background: The UK does not currently have guidelines on gestational weight gain owing to gaps in the evidence base. Reintroducing routine weighing of women throughout pregnancy would begin to provide the evidence needed to fill this gap. The aim of this research was to re-introduce measurement of weight at each routine antenatal appointment in a small scale study, in order to determine the feasibility and acceptability of implementing the practice on a larger scale.

Background: Weaning marks the transition from a milk-only diet to the consumption of solid foods. It is a time period where nutrition holds an undeniable importance and taste experiences have a long-lasting effect on food preferences. The factors and conditions that form parental feeding practices are yet to be fully understood; doing so can help target problematic behaviours and develop interventions aiming to modify them.

The initiation of complementary feeding (CF; introducing infants to food/drink other than milk) is recommended close to 6 months and not before 4 months of age. Low socio-economic status (SES) is a determinant of nonadherence to CF recommendations, but there is an evidence gap around reasons for nonadherence among these parents. This study investigated knowledge, attitudes, and practices of disadvantaged families (in terms of SES and social support) and use of guidance for CF, in the Republic of Ireland and Northern Ireland.

It is important to pay attention to weight management before and between pregnancies, as women have an increased risk of weight gain during the reproductive years. Having a baby is a life-changing event for women and the challenge of weight management amidst this period of major physiological, psychological and social change should not be underestimated. However, the postpartum period offers an opportune time for lifestyle interventions, as women may have heightened awareness of their own and their wider families' health.

Traditional theories of backward priming account only for the priming effects found at long stimulus onset asynchronies (SOAs). Here, we suggest that the presence of backward priming at short SOAs may be related to the integrative role of the cerebellum. Previous research has shown that the right cerebellum is involved in forward associative priming.

Objectives: The secreted metabolites of probiotics are cytoprotective to intestinal epithelium and have been shown to attenuate inflammation and reduce gut permeability. The present study was designed to determine the protective effects of probiotic conditioned media (PCM) from Bifidobacterium infantis (BCM) and Lactobacillus acidophilus (LCM) on interleukin (IL)-1β-induced intestinal barrier compromise.

Methods: The epithelial barrier was determined by measuring the transepithelial electrical resistance (TER) across a Caco-2 cell monolayer using a Transwell model.

Objective: This study aimed to evaluate the impact of a computer kiosk intervention on parents' self-reported safety knowledge as well as observed child safety seat, smoke alarm use, and safe poison storage and to compare self-reported versus observed behaviors.

Methods: A randomized controlled trial with 720 parents of young children (4 months to 5 years) was conducted in the pediatric emergency department of a level 1 pediatric trauma center. Enrolled parents received tailored safety information (intervention) or generic information (control) from a computer kiosk after completing a safety assessment.

Objective: The objective of this research was to examine the effectiveness of a brief behavioral intervention, provided at the time of diagnosis of pelvic inflammatory disease, on subsequent behaviors by patients who were urban adolescents in a community in which sexually transmitted infection was prevalent.

Methods: 121 adolescents aged 15 to 21 years with mild to moderate pelvic inflammatory disease were enrolled in a randomized trial. All participants received standardized care, completed baseline audio computerized self-interviews, received full courses of medication at discharge, and were interviewed after the 2-week treatment course.

Background: Pelvic radiographs are obtained frequently in pediatric blunt trauma. The authors hypothesize that there are clinical indicators that can predict pelvic fracture on a pelvic radiograph in the pediatric blunt trauma patient with a Glasgow Coma Scale score of 14 or 15.

Methods: A retrospective case-control study of 33 patients with pelvic fractures and 63 patients without pelvic fractures was performed.

Objectives: Outcomes of in-hospital pediatric cardiopulmonary arrest are dismal. Recent data suggest that the quality of basic and advanced life support delivered to adults is low and contributes to poor outcomes, but few data regarding pediatric events have been reported. The objectives of this study were to (1) measure the median elapsed time to initiate important resuscitation maneuvers in simulated pediatric medical emergencies (ie, "mock codes") and (2) identify the types and frequency of errors committed during pediatric mock codes.

Objectives: The effects of a computer kiosk intervention on parents' child safety seat, smoke alarm, and poison storage knowledge and behaviors were evaluated in a pediatric emergency department serving predominantly low-income, urban families. The effects of parent anxiety and the reason for the child's emergency department visit also were examined.

Methods: A randomized, controlled trial of a Safety in Seconds program with a 2- to 4-week follow-up interview was conducted with 759 parents of young children (4-66 months of age).
