Neurodevelopmental challenges are the most prevalent comorbidity associated with a diagnosis of critical CHD, and there is a high incidence of gross and fine motor delays noted in early infancy. The frequency of motor delays in hospitalised infants with critical CHD requires close monitoring from developmental therapies (physical therapists, occupational therapists, and speech-language pathologists) to optimise motor development. Currently, minimal literature defines developmental therapists’ role in caring for infants with critical CHD in intensive or acute care hospital units.

This article describes typical infant motor skill development, how the hospital environment and events surrounding early cardiac surgical interventions impact those skills, and how developmental therapists support motor skill acquisition in infants with critical CHD. Recommendations for healthcare professionals and those who provide medical or developmental support in promotion of optimal motor skill development in hospitalised infants with critical CHD are discussed.

Infants with critical CHD requiring neonatal surgical intervention experience interrupted motor skill interactions and developmental trajectories. As part of the interdisciplinary team working in intensive and acute care settings, developmental therapists assess, guide motor intervention, promote optimal motor skill acquisition, and support the infant’s overall development.

Parent and child mental health has suffered during the pandemic and transition phase. Structured and shared parenting may be intervention targets beneficial to families who are struggling with parent or child mental health challenges.

First, we investigated associations between structured and shared parenting and parent depression symptoms. Second, we investigated associations between structured and shared parenting and depression, hyperactivity/inattention and irritability symptoms in children.

A total of 1027 parents in two-parent households (4797 observations total; 85.1% mothers) completed online surveys about themselves and their children (aged 2–18 years) from April 2020 to July 2022. Structured parenting and shared parenting responsibilities were assessed from April 2020 to November 2021. Symptoms of parent depression, child depression, child hyperactivity and inattention, child irritability, and child emotional and conduct problems were assessed repeatedly (one to 14 times; median of four times) from April 2020 to July 2022.

Parents who reported higher levels of shared parenting responsibilities had lower depression symptoms (β = −0.09 to −0.32, all P < 0.01) longitudinally. Parents who reported higher levels of shared parenting responsibilities had children with fewer emotional problems (ages 2–5 years; β = −0.07, P < 0.05), fewer conduct problems (ages 2–5 years; β = −0.09, P < 0.01) and less irritability (ages 13–18 years; β = −0.27, P < 0.001) longitudinally. Structured parenting was associated with fewer conduct problems (ages 2–5 years; β = −0.05, P < 0.05).

Shared parenting is beneficial for parent and child mental health, even under chaotic or inflexible life conditions. Structured parenting is beneficial for younger children.

Lifetime radiation exposure for paediatric orthotopic heart transplant (OHT) patients is significant with cardiac catheterisation as the dominant source. Interventional cardiac magnetic resonance is utilised to obtain simultaneous, radiation-free haemodynamics and flow/function measurements. We sought to compare invasive haemodynamic measurements and radiation exposure in traditional cardiac catheterisation, to comprehensive interventional cardiac magnetic resonance.

Twenty-eight OHT patients who underwent 67 interventional cardiac magnetic resonance procedures at Children’s National Hospital were identified. Both invasive oximetry with peripheral oxygen saturation (Fick) and cardiac magnetic resonance phase contrast measurements of pulmonary and systemic blood flow were performed. Systemic and pulmonary blood flow from the two modalities was compared using Bland–Altman, concordance analysis, and inter-reader correlation. A mixed model was implemented to account for confounding variables and repeat encounters. Radiation dosage data were collected for a contemporaneous cohort of orthotopic heart transplant patients undergoing standard, X-ray-guided catheterisation.

Simultaneous cardiac magnetic resonance and Fick have poor agreement in our study based on Lin’s correlation coefficient of 0.68 and 0.73 for pulmonary and systemic blood flow, respectively. Bland–Altman analysis demonstrated a consistent over estimation of cardiac magnetic resonance cardiac output by Fick. The average indexed dose area product for patients undergoing haemodynamics with endomyocardial biopsy was 0.73 (SD ±0.6) Gy*m2/kg. With coronary angiography added, the indexed dose area product was 14.6 (SD ± 7.8) Gy*m2/kg.

Cardiac magnetic resonancemeasurements of cardiac output/index in paediatric orthotopic heart transplant patients have poor concordance with Fick estimates; however, cardiac magnetic resonance has good internal validity and inter-reader reliability. Radiation doses are small for haemodynamics with biopsy and increase exponentially with angiography, identifying a new target for cardiac magnetic resonance imaging.

The COVID-19 pandemic changed early care and education (ECE) mealtimes. Feeding practices that support children’s emerging autonomy may support children’s healthy eating, but it is unknown whether and how COVID-19 changed feeding practices. This paper describes caregiver feeding practices in ECE centres in Florida during COVID-19.

A mixed-methods design was used to understand mealtime feeding practices. Survey and interview questions were developed based on the Trust Model. More than 7000 surveys were sent to ECE centres. Analysis included descriptive statistics for survey data and thematic analysis for interview data.

This statewide study included teachers in all licensed and license-exempt ECE centres.

Four hundred and thirty-one teachers completed a survey, and twenty-nine participated in follow-up interviews.

Surveys showed most teachers engaged in autonomy-supportive behaviours, such as letting children eat until they were finished (90 %). The most common controlling behaviour was praising children for cleaning their plates (70 %). The most common responses about changes to mealtimes were keeping physical distance and serving healthy food. Interview themes were Autonomy Support, Controlling Feeding Practices, Interactions are the Same, Interactions are Different, Physical Distancing and Healthy Eating.

Mealtimes are a central part of the day for young children and teachers in ECE environments. COVID-19 continues to influence ECE routines as behaviour change remains the primary method of reducing the risk of COVID-19 in the absence of a vaccine for young children. Understanding teachers’ practices and perspectives is important for reducing the risk of COVID-19 and supporting children’s autonomy and healthy eating.

To prioritise and refine a set of evidence-informed statements into advice messages to promote vegetable liking in early childhood, and to determine applicability for dissemination of advice to relevant audiences.

A nominal group technique (NGT) workshop and a Delphi survey were conducted to prioritise and achieve consensus (≥70 % agreement) on thirty evidence-informed maternal (perinatal and lactation stage), infant (complementary feeding stage) and early years (family diet stage) vegetable-related advice messages. Messages were validated via triangulation analysis against the strength of evidence from an Umbrella review of strategies to increase children’s vegetable liking, and gaps in advice from a Desktop review of vegetable feeding advice.

Australia.

A purposeful sample of key stakeholders (NGT workshop, n 8 experts; Delphi survey, n 23 end users).

Participant consensus identified the most highly ranked priority messages associated with the strategies of: ‘in-utero exposure’ (perinatal and lactation, n 56 points) and ‘vegetable variety’ (complementary feeding, n 97 points; family diet, n 139 points). Triangulation revealed two strategies (‘repeated exposure’ and ‘variety’) and their associated advice messages suitable for policy and practice, twelve for research and four for food industry.

Supported by national and state feeding guideline documents and resources, the advice messages relating to ‘repeated exposure’ and ‘variety’ to increase vegetable liking can be communicated to families and caregivers by healthcare practitioners. The food industry provides a vehicle for advice promotion and product development. Further research, where stronger evidence is needed, could further inform strategies for policy and practice, and food industry application.

A recent genome-wide association study (GWAS) identified 12 independent loci significantly associated with attention-deficit/hyperactivity disorder (ADHD). Polygenic risk scores (PRS), derived from the GWAS, can be used to assess genetic overlap between ADHD and other traits. Using ADHD samples from several international sites, we derived PRS for ADHD from the recent GWAS to test whether genetic variants that contribute to ADHD also influence two cognitive functions that show strong association with ADHD: attention regulation and response inhibition, captured by reaction time variability (RTV) and commission errors (CE).

The discovery GWAS included 19 099 ADHD cases and 34 194 control participants. The combined target sample included 845 people with ADHD (age: 8–40 years). RTV and CE were available from reaction time and response inhibition tasks. ADHD PRS were calculated from the GWAS using a leave-one-study-out approach. Regression analyses were run to investigate whether ADHD PRS were associated with CE and RTV. Results across sites were combined via random effect meta-analyses.

When combining the studies in meta-analyses, results were significant for RTV (R2 = 0.011, β = 0.088, p = 0.02) but not for CE (R2 = 0.011, β = 0.013, p = 0.732). No significant association was found between ADHD PRS and RTV or CE in any sample individually (p > 0.10).

We detected a significant association between PRS for ADHD and RTV (but not CE) in individuals with ADHD, suggesting that common genetic risk variants for ADHD influence attention regulation.

To analyse nutritional and packaging characteristics of toddler-specific foods and milks in the Australian retail food environment to identify how such products fit within the Australian Dietary Guidelines (ADG) and the NOVA classification.

Cross-sectional retail audit of toddler foods and milks. On-pack product attributes were recorded. Products were categorised as (1) food or milk; (2) snack food or meal and (3) snacks sub-categorised depending on main ingredients. Products were classified as a discretionary or core food as per the ADG and level of processing according to NOVA classification.

Supermarkets and pharmacies in Australia.

A total of 154 foods and thirty-two milks were identified. Eighty percentage of foods were snacks, and 60 % of foods were classified as core foods, while 85 % were ultraprocessed (UP). Per 100 g, discretionary foods provided significantly more energy, protein, total and saturated fat, carbohydrate, total sugar and Na (P < 0·001) than core foods. Total sugars were significantly higher (P < 0·001) and Na significantly lower (P < 0·001) in minimally processed foods than in UP foods. All toddler milks (n 32) were found to have higher energy, carbohydrate and total sugar levels than full-fat cow’s milk per 100 ml. Claims and messages were present on 99 % of foods and all milks.

The majority of toddler foods available in Australia are UP snack foods and do not align with the ADG. Toddler milks, despite being UP, do align with the ADG. A strengthened regulatory approach may address this issue.

Treatment of hypoplastic left heart syndrome varies across institutions. This study examined the impact of introducing a standardised programme.

This retrospective cohort study evaluated the effects of a comprehensive strategy on 1-year transplant-free survival with preserved ventricular and atrioventricular valve (AVV) function following a Norwood operation. This strategy included standardised operative and perioperative management and dedicated interstage monitoring. The post-implementation cohort (C2) was compared to historic controls (C1). Outcomes were assessed using logistic regression and Kaplan–Meier analysis.

The study included 105 patients, 76 in C1 and 29 in C2. Groups had similar baseline characteristics, including percentage with preserved ventricular (96% C1 versus 100% C2, p = 0.28) and AVV function (97% C1 versus 93% C2, p = 0.31). Perioperatively, C2 had higher indexed oxygen delivery (348 ± 67 ml/minute/m2 C1 versus 402 ± 102ml/minute/m2 C2, p = 0.015) and lower renal injury (47% C1 versus 3% C2, p = 0.004). The primary outcome was similar in both groups (49% C1 and 52% C2, p = 0.78), with comparable rates of death and transplantation (36% C1 versus 38% C2, p = 0.89) and ventricular (2% C1 versus 0% C2, p = 0.53) and AVV dysfunction (11% C1 versus 11% C2, p = 0.96) at 1-year. When accounting for cohort and 100-day freedom from hospitalisation, female gender (OR 3.7, p = 0.01) increased and ventricular dysfunction (OR 0.21, p = 0.02) and CPR (OR 0.11, p = 0.002) or ECMO use (OR 0.15, p = 001) decreased the likelihood of 1-year transplant-free survival.

Standardised perioperative management was not associated with improved 1-year transplant-free survival. Post-operative ventricular or AVV dysfunction was the strongest predictor of 1-year mortality.

Even though sub-Saharan African women spend millions of person-hours per day fetching water and pounding grain, to date, few studies have rigorously assessed the energy expenditure costs of such domestic activities. As a result, most analyses that consider head-hauling water or hand pounding of grain with a mortar and pestle (pilão use) employ energy expenditure values derived from limited research. The current paper compares estimated energy expenditure values from heart rate monitors v. indirect calorimetry in order to understand some of the limitations with using such monitors to measure domestic activities.

This confirmation study estimates the metabolic equivalent of task (MET) value for head-hauling water and hand-pounding grain using both indirect calorimetry and heart rate monitors under laboratory conditions.

The study was conducted in Nampula, Mozambique.

Forty university students in Nampula city who recurrently engaged in water-fetching activities.

Including all participants, the mean MET value for head hauling 20 litres (20·5 kg, including container) of water (2·7 km/h, 0 % slope) was 4·3 (sd 0·9) and 3·7 (sd 1·2) for pilão use. Estimated energy expenditure predictions from a mixed model were found to correlate with observed energy expenditure (r2 0·68, r 0·82). Re-estimating the model with pilão use data excluded improved the fit substantially (r2 0·83, r 0·91).

The current study finds that heart rate monitors are suitable instruments for providing accurate quantification of energy expenditure for some domestic activities, such as head-hauling water, but are not appropriate for quantifying expenditures of other activities, such as hand-pounding grain.
