Using the RE-AIM framework to evaluate the feasibility of a parent-focused intervention targeting childhood obesity.

BACKGROUND: Childhood obesity remains a serious public health concern. Community-based childhood obesity treatment interventions have the potential to improve health behaviors and outcomes among children, but require thorough evaluation to facilitate translation of research into practice. The purpose of the current study was to determine the feasibility of a community-based, parent-focused childhood obesity intervention ("C.H.A.M.P. Families") using the RE-AIM framework, an evaluation tool for health interventions. METHODS: A single-group, non-randomized, repeated measures feasibility study was conducted. Participants (n = 16 parents/caregivers of 11 children with obesity) completed a 13-week parent-focused education intervention. The intervention consisted of three main components: (a) eight group-based (parent-only) education sessions; (b) eight home-based (family-centered) activities; and (c) two group-based follow-up support sessions for parents and children. The five dimensions of RE-AIM-reach, effectiveness, adoption, implementation, and maintenance-were assessed using various measures and data sources (e.g., child, parent/caregiver, costing, census) obtained throughout the study period. Outcome variables were measured at baseline, mid-intervention, post-intervention, and at a 6-month follow-up. RESULTS: Overall, the C.H.A.M.P. Families intervention reached approximately 0.09% of eligible families in London, Ontario. Despite the small number, participants were generally representative of the population from which they were drawn, and program participation rates were high (reach). Findings also suggest that involvement in the program was associated with improved health-related quality of life among children (effectiveness/individual-level maintenance). In addition, the intervention had high fidelity to protocol, attendance rates, and cost-effectiveness (implementation). Lastly, important community partnerships were established and maintained (adoption/setting-level maintenance). CONCLUSIONS: Based on a detailed and comprehensive RE-AIM evaluation, the C.H.A.M.P. Families intervention appears to be a promising parent-focused approach to the treatment of childhood obesity. TRIAL REGISTRATION: ISRCTN Registry, Study ID ISRCTN 10752416 .

Saline-Lock Versus Continuous Infusion: Maintaining Peripheral Intravenous Catheter Access in Children.

OBJECTIVES: In children, peripheral intravenous catheters (PIVs) are maintained by either a continuous infusion of fluid "to keep vein open" (TKO) or a saline lock (SL). There is a widespread perception that TKO prolongs PIV patency, but there is a lack of evidence for this. We hypothesized that there would be no significant difference in duration of PIV patency between TKO and SL. PATIENTS AND METHODS: This prospective, time-allocated study included patients from newborn to 17 years of age admitted to our pediatric ward. Patients enrolled in the first 3 months were assigned to TKO, and patients in the latter 3 months were assigned to SL. Primary outcome was duration of functional patency of the first PIV during the time of TKO or SL. Secondary outcomes included PIV-related complications and patient and caregiver satisfaction. RESULTS: Complete PIV data were available on 172 (n = 85 TKO, n = 87 SL) of 194 enrolled patients. The mean (SD) duration of PIV patency was 41.68 (41.71) hours in the TKO group and 44.05 (41.46) hours in the SL group, which was not significantly different (P = .71). There were no significant differences in complication rates or overall patient and caregiver satisfaction. One patient in the TKO group had their PIV removed because of risk of strangulation from tubing. CONCLUSION: There were no significant differences between TKO and SL in the duration of PIV patency, complication rates, and overall patient and caregiver satisfaction in our pediatric population. Overall, SL is a safe and reasonable alternative to TKO in maintaining PIV patency in children.

Infective Endarteritis and Mycotic Pseudoaneurysms in a Pediatric Patient With Aortic Coarctation.

An 11-year-old boy presented with Staphylococcus aureus infective endarteritis and mycotic pseudoaneurysms within the context of a previously undiagnosed aortic coarctation. He had an urgent resection of the pseudoaneurysm and coarctation repair. Nuances to his initial diagnosis and key learning points related to the complication of pseudoaneurysm are discussed.

Vitamin D in the prevention of exacerbations of asthma in preschoolers (DIVA): protocol for a multicentre randomised placebo-controlled triple-blind trial.

INTRODUCTION: Preschoolers have the highest rate of emergency visits and hospitalisations for asthma exacerbations of all age groups, with most triggered by upper respiratory tract infections (URTIs) and occurring in the fall or winter. Vitamin D insufficiency is highly prevalent in Canadian preschoolers with recurrent asthma exacerbations, particularly in winter. It is associated with more URTIs and, in patients with asthma, more oral corticosteroid (OCS) use. Although evidence suggests that vitamin D supplements significantly decrease URTIs and asthma exacerbations requiring OCS, there is insufficient data in preschoolers. This study aims to determine the impact of vitamin D3 supplementation on exacerbations requiring OCS, in preschoolers with recurrent URTI-induced asthma exacerbations. METHODS AND ANALYSIS: This is a phase III, randomised, triple-blind, placebo-controlled, parallel-group multicentre trial of vitamin D3 supplementation in children aged 1-5 years, with asthma triggered by URTIs and a recent history of frequent URTIs and OCS use. Children (n=865) will be recruited in the fall and early winter and followed for 7 months. They will be randomised to either the (1) intervention: two oral boluses of 100 000 international unit (IU) vitamin D3 (3.5 months apart) with 400 IU vitamin D3 daily; or (2) control: identical placebo boluses with daily placebo. The primary outcome is the number of exacerbations requiring OCS per child, documented by medical and pharmacy records. Secondary outcomes include number of laboratory-confirmed viral URTIs, exacerbation duration and severity, parent functional status, healthcare use, treatment deintensification, cost and safety. ETHICS AND DISSEMINATION: This study has received ethical approval from all sites. Results will be disseminated via international conferences and manuscripts targeting paediatricians and respirologists, and to families of asthmatic children via our Quebec parents-partners outreach programme. If proven effective, findings may markedly influence the management of URTI-induced asthma in high-morbidity preschoolers and could be directly implemented into practice with an update to clinical guidelines.

"C.H.A.M.P. Families": Description and Theoretical Foundations of a Paediatric Overweight and Obesity Intervention Targeting Parents-A Single-Centre Non-Randomised Feasibility Study.

Childhood obesity represents a significant global health challenge, and treatment interventions are needed. The purpose of this paper is to describe the components and theoretical model that was used in the development and implementation of a unique parent-focussed paediatric overweight/obesity intervention. C.H.A.M.P. Families was a single-centre, prospective intervention offered to parents of children aged between 6⁻14 years with a body mass index (BMI) ≥85th percentile for age and sex. The intervention included: (1) eight group-based (parent-only) education sessions over 13-weeks; (2) eight home-based activities; and (3) two group-based (family) follow-up support sessions. The first section of the manuscript contains a detailed description of each intervention component, as well as an overview of ongoing feasibility analyses. The theoretical portion details the use of evidence-based group dynamics principles and motivational interviewing techniques within the context of a broader social cognitive theory foundation. This paper provides researchers with practical examples of how theoretical constructs and evidence-based strategies can be applied in the development and implementation of parent-focussed paediatric obesity interventions. Given the need for transparent reporting of intervention designs and theoretical foundations, this paper also adds to the areas of implementation science and knowledge translation research.

Sleep-promoting medications in children: physician prescribing habits in Southwestern Ontario, Canada.

BACKGROUND: Research indicates that physicians may frequently use pharmacotherapy to treat pediatric insomnia despite minimal safety data and very limited indications. Canadian data on the subject are lacking. This study aimed to determine physicians' views on and prescribing habits for sleep-promoting over-the-counter medication (OTCM) and prescription (RXM) medications for children. METHODS: A modified 26-item version of the 'Pediatric Sleep Medication Survey', originally developed by Judith Owens and colleagues, was sent to 100 pediatricians and a random sample of 421 family physicians in Southwestern Ontario, Canada. RESULTS: A total of 67 returned surveys were sufficiently complete for analysis. Sixty-one respondents indicated their specialty (28 pediatricians, 33 family physicians). In a typical 6-month period, 89% and 66% of respondents have recommended OTCM and RXM, respectively, for children with sleep problems. Only 20% have received any formal training on pediatric sleep disorders. The most common circumstances and sleep problems for which OTCM or RXM were recommended were mood disorders, developmental delay and attention deficit hyperactivity disorder (ADHD) (56, 40, and 39%, respectively), and insomnia, bedtime struggles/delayed sleep onset and circadian rhythm disorders (52, 48, and 28%, respectively). A total of 30% recommended OTCM or RXM to otherwise healthy children with sleep problems. Melatonin (73%), OTC antihistamines (41%), antidepressants (37%), and benzodiazepines (29%) were the most commonly recommended OTCM and RXM, respectively. CONCLUSIONS: Respondents in our sample frequently use pharmacotherapy to treat pediatric sleep problems; few have received any training in this area. Our findings indicate the need for evidence-based guidelines and regular physician training in the management of pediatric sleep disorders.

The Health Initiative Program for Kids (HIP Kids): effects of a 1-year multidisciplinary lifestyle intervention on adiposity and quality of life in obese children and adolescents--a longitudinal pilot intervention study.

BACKGROUND: Though recent data suggest that multidisciplinary outpatient interventions can have a positive effect on childhood obesity, it is still unclear which program components are most beneficial and how they affect quality of life (QoL). The aim of this study was to determine if a 1-year multidisciplinary, family-centered outpatient intervention based on social cognitive theory would be effective in (i) preventing further increases in BMI and BMI z-score, and (ii) improving QoL in obese children and adolescents. METHODS: Obese children and adolescents 8-17 years of age and their families participated in this 1-year longitudinal pilot intervention study. The intervention consisted of fifteen 90-minute educational sessions led by a dietitian, exercise specialist, and social worker. Anthropometric measures, body composition, and QoL (Pediatric Quality of Life Inventory 4.0), were assessed at baseline, 3 months, and 12 months. Laboratory values were measured at baseline and 12 months. The primary outcome measures were change in BMI and BMI z-score, secondary outcome measures included change in QoL and body composition. A paired sample t-test was used to assess within-group differences and 95% confidence intervals were reported for the mean differences. RESULTS: 42 obese children and adolescents (21 girls) completed the 1-year intervention (mean age 12.8 ± 3.14 years). Mean baseline BMI was 31.96 ± 5.94 kg/m(2) and BMI z-score was +2.19 ± 0.34. Baseline QoL (self-assessments and parental assessments) was impaired: mean baseline scores were 74.5 ± 16.5 and 63.7 ± 19.4 for physical functioning and 69.0 ± 14.9 and 64.0 ± 18.3 for emotional functioning, respectively. At 12 months, BMI z-score had decreased (-0.07 ± 0.11, 95% CI: -0.11 to -0.04). BMI (0.80 ± 1.57 kg/m(2), 95% CI 0.31 to 1.29) and fat-free mass (4.02 ± 6.27 kg, 95% CI 1.90 to 6.14) increased, but % body fat and waist circumference did not. Both the parent-reported physical (11.3 ± 19.2, 95% CI 4.7 to 17.9) and emotional (7.7 ± 15.7, 95% CI 2.3 to 13.0) functioning QoL scores and the children's self-reported physical (5.3 ± 17.1, 95% CI 0.5 to 11.1) and emotional (7.9 ± 14.3, 95% CI 3.2 to 12.7) functioning scores significantly improved. CONCLUSIONS: Following a 1-year intervention, the participants' BMI z-scores and QoL improved, while other adiposity-related measures of body composition remained unchanged.

Asymptomatic critical hypoglycaemia: a dangerous presentation of glycogen storage disease type Ib in infancy.

UNLABELLED: We report the case of a 3-month-old boy who presented with a 3-day history of respiratory tract infection and poor feeding. He was incidentally found to have profound hypoglycaemia, high-anion-gap lactic acidosis, ketonuria, hyperlipidemia, hepatomegaly, growth failure and neutropenia. Glycogen storage disease type Ib (GSD Ib), an autosomal recessive metabolic defect of the microsomal transporter glucose-6-phosphate-translocase, was suspected and confirmed by genetic testing. Treatment consisted of initial intravenous glucose and fluids to correct his lactic acidosis, followed by a strict dietary protocol consisting of soy-based infant formula enriched with glucose polymers from cornstarch and overnight gastrostomy feeds. CONCLUSIONS: GSD I should be considered in all young children presenting with hypoglycaemia and lactic acidosis. Presence of neutropenia further confirms GSD Ib. Even critical hypoglycaemia can be clinically unapparent in affected children.
