Although sucrose is widely administered to hospitalized infants for single painful procedures, total sucrose volume during the entire neonatal intensive care unit (NICU) stay and associated adverse events are unknown. In a longitudinal observation study, we aimed to quantify and contextualize sucrose administration during the NICU stay. Specifically, we investigated the frequency, nature, and severity of painful procedures; proportion of procedures where neonates received sucrose; total volume of sucrose administered for painful procedures; and incidence and type of adverse events. Neonates <32 weeks gestational age at birth and <10 days of life were recruited from four Canadian tertiary NICUs. Daily chart reviews of documented painful procedures, sucrose administration, and any associated adverse events were undertaken. One hundred sixty‐eight neonates underwent a total of 9093 skin‐breaking procedures (mean 54.1 [±65.2] procedures/neonate or 1.1 [±0.9] procedures/day/neonate) during an average NICU stay of 45.9 (±31.4) days. Pain severity was recorded for 5399/9093 (59.4%) of the painful procedures; the majority (5051 [93.5%]) were heel lances of moderate pain intensity. Sucrose was administered for 7839/9093 (86.2%) of painful procedures. The total average sucrose volume was 5.5 (±5.4) mL/neonate or 0.11 (±0.08) mL/neonate/day. Infants experienced an average of 7.9 (±12.7) minor adverse events associated with pain and/or sucrose administration that resolved without intervention. The total number of painful procedures, sucrose volume, and incidence of adverse events throughout the NICU stay were described addressing an important knowledge gap in neonatal pain. These data provide a baseline for examining the association between total sucrose volume during NICU stay and research on longer‐term behavioral and neurodevelopmental outcomes.

Child homicides are rare occurrences, but when they occur, they often cause significant outrage. This paper examines the role of varying degrees of intimacy between victims and perpetrators in determining characteristics in child homicide cases. Focusing on 533 cases of child homicide between 1985 and 2012 in Ontario, Canada, characteristics of intrafamilial and extrafamilial cases, biological and step/foster parents, and maternal and paternal perpetrators are compared. Results show that characteristics of the child homicide vary depending on the degree of intimacy between victims and perpetrators, including: perpetrator and victim age, weapon use, suicide following the offence, sexual violence and use of excessive force. These findings provide support for developmental victimology and a routine activities theoretical perspective. Suggestions for future research and policy implications are also discussed. 'Examines the role of varying degrees of intimacy between victims and perpetrators in determining characteristics in child homicide cases' Key Practitioner Messages: Younger children are at a greater risk of homicide from family members, while older children are at a greater risk of homicide from individuals outside the family.Developmental victimology and routine activities theory can contribute to a better understanding of the dynamics between victims and perpetrators in child homicide.Collaboration should take place between researchers, child death review committees, mental health services, social services and policymakers to improve child homicide prevention and intervention initiatives.

BACKGROUND: The present study aimed to characterize the behavior of 3 components of respiratory muscle function during mechanical ventilation weaning in children to better understand the respective impact of a spontaneous breathing trial on ventilatory mechanical action (esophageal pressure [Pes], ventilatory demand (electrical activity of the diaphragm [EAdi]), and oxygen consumption. METHODS: This was a prospective single-center study. All children > 1 months and <18 y old who were intubated and on mechanical ventilation, and who were hospitalized in the pediatric ICU were eligible. Subjects considered as ready to extubate were included. Simultaneous recordings of oxygen consumption, Pes, and EAdi were performed during 3 steps: before, during, and after the spontaneous breathing test. RESULTS: Twenty subjects (median age, 5.5 mo) were included. Half of them were admitted for a respiratory cause. The increase in Pes swings and esophageal pressure-time product during the spontaneous breathing trial was not significant (P = .33 and P = .75, respectively), and a similar trend was observed with peak EAdi (P = .06). Oxygen consumption obtained by indirect calorimetry was stable in the 3 conditions (P = .98). CONCLUSIONS: In these children who were critically ill, a spontaneous breathing trial induced a moderate and nonsignificant increase in work of breathing, as reflected by the respiratory drive with EAdi and respiratory mechanics with Pes. However, indirect calorimetry did not seem to be a sensitive tool to assess respiratory muscle function during the weaning phase in children who were on mechanical ventilation, especially when work of breathing was slightly increased.

Aims To examine the effect of a pre-operative DVD on parents' knowledge, participation and anxiety and on children's distress, pain, analgesic requirements and length of recovery after same-day surgery. Background Very few parents are adequately prepared to participate in their child's care during a same-day surgery. An educational DVD was developed to educate parents on how to actively support their child in the recovery room. Design Single-blind, post-test randomized controlled trial. Study is registered at ClinicalTrials.gov NCT02766452. Methods Between September 2011-September 2012, 123 parent-child dyads where the child underwent an ENT or dental same-day surgery were recruited in a Canadian paediatric hospital. Dyads were randomly assigned to either the intervention ( DVD and standard preparation) or control group (standard preparation). Parents and children were videotaped in the recovery room where parental participation and anxiety and children's distress were measured. Data on parents' knowledge, children's postoperative pain, analgesic requirements and length of recovery were measured. Independent and paired t-tests, chi square and repeated measures anova were used to analyse the data. Results Parents in the intervention group gained greater knowledge of and used more positive reinforcement and distraction and relaxation methods than those in the control group. Children's postoperative pain in the day-care surgery unit was significantly lower among the intervention group compared with the control group. Conclusion A pre-operative DVD can increase parents' participation in the recovery room and decrease children's postoperative pain. [ABSTRACT FROM AUTHOR]

There are some children who encounter unexpected reading difficulties in the fourth grade. This phenomenon has been described as late emerging reading disabilities (LERD). Using Grade 4 as a starting point, this study examined the reading development of 964 children between kindergarten and Grade 7. The results showed that 72.0% of children had typical reading performance in Grade 4, whereas there was 0.7% with poor word reading, 12.6% with poor reading comprehension, 2.5% with poor word reading and comprehension, and 12.2% with borderline performance. We also showed that there were similar proportions of children who had early versus late emerging reading difficulties; however, most of the late emerging poor readers recovered by Grade 7. Furthermore, our study showed that poor comprehenders showed poorer performance than typical readers on word reading, pseudoword decoding, and spelling between Grade 1 and Grade 7 and poorer performance on a working memory task in kindergarten. Overall, this study showed that most children recover from late emerging reading problems and that working memory may be an early indicator for reading comprehension difficulties.

Background: Vitamin D is fundamental for bone health. A high proportion of Canadian 2- to 8-y-olds do not meet the Estimated Average Requirement (EAR) of 400 IU/d. Objective: The objective was to determine whether vitamin D intakes consistent with the EAR or Recommended Dietary Allowance (RDA), through fortification of additional dairy products, would result in higher vitamin D status in young children. Design: Participants aged 2-8 y (n = 77; Montreal, Canada) were randomly assigned to 1 of 3 dietary vitamin D targets (control; EAR: 400 IU/d; or RDA: 600 IU/d) for 12 wk (January to April 2014). Anthropometric measurements, demographic characteristics, dietary intakes, fasting serum parathyroid hormone, 25-hydroxyvitamin D [25(OH)D], and ionized calcium were compared by using mixed-model ANOVA. Results: Participants' mean ± SD age was 5.1 ± 1.9 y; 54.5% were boys with body mass index z scores of 0.50 ± 0.85. Compliance was 85% overall. No differences were observed in baseline dietary vitamin D intakes or serum 25(OH)D. At 12 wk, the EAR and RDA groups had significantly higher vitamin D intakes [median (IQR): control, 227 (184-305) IU/d; EAR, 410 (363-516) IU/d; and RDA, 554 (493-653) IU/d; P < 0.05] and serum 25(OH)D concentrations (control: 55.8 ± 12.3 nmol/L; EAR: 64.1 ± 10.0 nmol/L; and RDA: 63.7 ± 12.4 nmol/L; P < 0.05) than the control group. Ninety-six percent of children in the EAR and RDA groups and 67% of the control group had 25(OH)D concentrations ≥50 nmol/L. Conclusion: Increasing the vitamin D intakes of young children through fortification of alternative dairy products results in significantly higher serum concentrations of 25(OH)D and a significantly greater proportion of children with serum 25(OH)D ≥50 nmol/L during periods of minimal ultraviolet B radiation exposure. This trial was registered at clinicaltrials.gov as NCT02097160 and had Health Canada Temporary Marketing Authorization Letters for both products (TM-13-0432 and TM-13-0433). [ABSTRACT FROM AUTHOR]

Background The body of literature on narratives of bilingual children with and without specific language impairment (SLI) is growing. However, little is known about the narrative abilities of bilingual preschool children with SLI and their patterns of growth. Aims To determine the similarities and differences in narrative abilities between preschoolers with and without SLI who are either monolingual or bilingual at two time points. Methods & Procedures Forty children completed a narrative retell task in English at two test points. The mean ages were 52 and 58 months at Times 1 and 2, respectively. We examined performance on measures of narrative macrostructure (narrative information) and microstructure (sentence length, number of different words, verb accuracy, first mentions) in monolingual and bilingual children with and without SLI. The bilingual children were from diverse first-language backgrounds and all spoke English most of the time. Outcomes & Results A series of repeated-measures analyses of variance was used with language ability (typical development or SLI) and bilingual status (monolingual versus bilingual) as the between-subjects factors and time (Times 1 or 2) as the within-subjects factor. Results indicated a significant main effect of time for four measures (i.e., Information Score, lexical diversity, sentence length and verb accuracy). The between-subjects analyses indicated a significant difference between the typically developing children and the children with SLI in all measures and a significant difference between monolingual and bilingual children for verb accuracy only. Conclusions & Implications This study showed that all four groups of children showed growth over a 6-month period and that bilingual children exposed predominantly to English in the home performed similarly to their monolingual peers in measures of narrative information, sentence length, number of different words and first mentions.

Objective The aim of this study was to compare parents' expectations for their children crossing streets' with children s actual crossing behaviours and determine how accurately parents judge their own children's pedestrian behaviours to be. Method Using a fully immersive virtual reality system interfaced with a 3D movement measurement system, younger (7-9 years) and older (10-12 years) children's crossing behaviours were assessed. The parent viewed the same traffic conditions and indicated if their child would cross and how successful she/he expected the child would be when doing so. Results Comparing children's performance with what their parents expected they would do revealed that parents significantly overestimated the inter-vehicle gap threshold of their children, erroneously assuming that children would show safer pedestrian behaviours and select larger inter-vehicle gaps to cross into than they actually did; there were no effects of child age or sex. Child and parent scores were not correlated and a logistic regression indicated these were independent of one another. Conclusions Parents were not accurate in estimating the traffic conditions under which their children would try and cross the street. If parents are not adequately supervising when children cross streets, they may be placing their children at risk of pedestrian injury because they are assuming their children will select larger (safer) inter-vehicle gaps when crossing than children actually do.

Little is known about the influence of different forms of added sugar intake on diet quality or their association with obesity among youth. Dietary intake was assessed by three 24-h recalls in 613 Canadian children (aged 8-10 years). Added sugars (mean of 3-day intakes) were categorized according to source (solid or liquid). Dietary intake and the Canadian Healthy Eating Index (« HEI-C ») were compared across tertiles of solid and liquid added sugars separately as were adiposity indicators (body mass index (BMI), fat mass (dual-energy X-ray absorptiometry), and waist circumference). Cross-sectional associations were examined in linear regression models adjusting for age, sex, energy intake, and physical activity (7-day accelerometer). Added sugar contributed 12% of total energy intake (204 kcal) on average, of which 78% was from solid sources. Higher consumption of added sugars from either solid or liquid source was associated with higher total energy, lower intake of micronutrients, vegetables and fruit, and lower HEI-C score. Additionally liquid sources were associated with lower intake of dairy products. A 10-g higher consumption of added sugars from liquid sources was associated with 0.4 serving/day lower of vegetables and fruit, 0.4-kg/m2 higher BMI, a 0.5-kg higher fat mass, and a 0.9-cm higher waist circumference whereas the associations of added sugars from solid sources and adiposity indicators tended to be negative. In conclusion, higher consumption of added sugar from either solid or liquid sources was associated with lower overall diet quality. Adiposity indicators were only positively associated with added sugars from liquid sources. [ABSTRACT FROM AUTHOR]
