Objective: To explore associations between maternal body mass index (BMI) in early pregnancy and childhood infections.

Design: Birth cohort study linked to primary care records.

Setting: Bradford, UK.

Participants: Live singleton births within the Born in Bradford cohort study between 2007 and 2011.

Exposures: Maternal BMI in early pregnancy.

Main outcome measures: The total number of infections between birth and ~14 years of age with subgroup analysis by infection type and age.

Results: A total of 9037 mothers and 9540 children were included in the main analysis. 45% of women were of Pakistani ethnicity and 6417 women (56%) were overweight or obese. There was an overall trend for an increasing infection rate with increasing maternal BMI. In adjusted models, only those with obesity grade 2-3 had offspring with significantly higher rates of infection during the first year of life (RR 1.12 (95% CI 1.05 to 1.20)) compared with women of healthy weight. However, by age 5 to <15 years, children born to overweight women (RR 1.09 (95% CI 1.02 to 1.16)), obese grade 1 women (RR 1.18 (95% CI 1.09 to 1.28)) or obese grade 2 women (RR 1.31 (95% CI 1.16 to 1.48)) all had significantly higher rates of infection compared with those born to healthy weight mothers. Respiratory tract and skin/soft tissue infections made up the majority of excess infections.

Conclusions: Maternal BMI was positively associated with rates of offspring infection in this study cohort, and suggests that we should be supporting women to achieve a healthy weight for pregnancy. Future research should investigate whether this is replicated in other populations, whether there is a causal association and the potential mechanisms and areas for intervention.

Objective: Beta-lactam antibiotic allergies are reported in 5%-10% of children; however, up to 90% do not have any reaction at oral challenge test (OCT). This study aimed to determine the frequency and identify predictors of positive in-hospital graded beta-lactam OCTs in children with a beta-lactam antibiotic allergy label (AAL).

Design: This is a retrospective study conducted over 7 years, including children aged 0-19 years who underwent a beta-lactam OCT. The OCT comprised an in-hospital graded challenge followed by a 5-day outpatient antibiotic course. Univariate and multivariate logistic regression analyses were performed to identify predictors of a positive in-hospital graded OCT.

Results: Overall, 1259 beta-lactam OCTs were included: median age at time of OCT was 6.3 years (range 8.8 months to 19.2 years). Of these, 18 (1.4%) in-hospital graded OCTs were positive and 10 (0.8%) were equivocal, with only 4 children (0.3%) having an immediate, severe reaction to their in-hospital graded OCT. Factors associated with a positive in-hospital graded OCT on univariate analysis were: history of other drug allergy (OR 2.7, 95% CI 1.0 to 7.2; p 0.05), an index reaction which was severe (OR 2.9, 95% CI 1.1 to 7.6; p 0.035), immediate and severe (OR 5.85, 95% CI 1.7 to 20.0; p 0.005) or that required epinephrine (OR 9.65, 95% CI 1.7 to 53.6; p 0.01).

Conclusion: Of the children referred with a beta-lactam AAL, only 1.4% had a positive in-hospital graded OCT. Risk factors for a positive in-hospital graded OCT were history of other drug allergy, an index reaction which was severe, immediate and severe or required epinephrine.

Objective: To evaluate the use of a questionnaire-based decision-making algorithm to triage children with reported antibiotic allergies to proceed directly to an oral provocation challenge.

Design: Cohort study.

Setting: Children aged 2-16 years attending paediatric emergency department over 1 year (1 June 2018 till 31 May 2019) or identified from four primary care centres in Sheffield with a recorded antibiotic allergy and no previous testing.

Participants: 313 children with 325 recorded antibiotic allergies.

Exposure: Clinical decision-making algorithm used to either exclude, directly delabel or stratify children to oral antibiotic challenge in outpatient department or primary care practice.

Main outcome measures: To assess the safety of using the questionnaire-based algorithm for proceeding to a direct oral provocation challenge.The secondary outcomes were to look for associations and predictive factors in positive challenges and to assess parent/carer acceptability of the service by using Likert Scale.

Results: Successful contact was made with 200 children, of which 153 children could be evaluated based on inclusion criteria, engagement and availability of medical records.15 children were directly delabelled based on history and records. 138 children underwent challenges in outpatient and primary care. 6% of challenges were reactive with a mild, delayed reaction. Overall, a delabelling rate of 91% was achieved. There were no clear predictors for a positive challenge.

Conclusion: Our questionnaire-based algorithm for stratifying children with antibiotic allergies to proceed directly to an oral outpatient or primary care challenge was found to be safe, feasible and acceptable.

Background: Trauma is a leading cause of mortality and morbidity in children worldwide. While adult studies have demonstrated hypocalcaemia's association with adverse outcomes, its impact on paediatric trauma patients remains understudied. This systematic review aims to investigate current evidence into the prevalence, clinical implications and associations of hypocalcaemia in paediatric trauma.

Methods: A comprehensive literature search was conducted searching four databases, grey literature and additional sources for original studies looking at outcomes for paediatric trauma patients with ionised calcium measurements before blood product administration. Exclusion criteria comprised studies which included patients with blood product administration prior to calcium measurement, case reports, case series, reviews and papers not available in English. The review protocol is registered with the International Prospective Register of Systematic Reviews (PROSPERO): CRD42023432473. Data extraction was performed on included papers and quality assessment performed using Newcastle-Ottawa Scale.

Results: Of 779 initial studies, two studies met inclusion criteria for detailed analysis. Both retrospective cohort studies originated in Israel and collectively included 568 patients. Hypocalcaemia incidence ranged from 5.3% to 19.8%. Although trends towards increased mortality, blood transfusion requirements and prolonged hospital stays were observed in patients with hypocalcaemia, statistical significance was not consistently achieved.

Conclusion: Hypocalcaemia in paediatric trauma appears reduced in incidence compared with adult populations. Limited available studies suggest potential associations with adverse outcomes, although most were not statistically significant. Studies had small patient numbers, necessitating further prospective research to facilitate a clearer understanding. Insights from such studies can guide patient management and improve outcomes in this vulnerable population.

Objective: The aim of this study was to explore parents' views and experiences of managing preschool wheeze, including opinions on the use of investigations to inform treatment pathways.

Design: Purposive sampling was used to recruit 16 participants from 14 families across England and Wales. Qualitative data were collected via semi-structured interviews with parents of children aged 1-5 years with preschool wheeze, conducted on Microsoft (MS) Teams. Data were transcribed and analysed using thematic analysis, facilitated by NVivo software package.

Results: Analysis generated four themes: (1) pathway to diagnosis, (2) medication management, (3) living with preschool wheeze and (4) improving preschool wheeze healthcare. Findings suggest a negative impact of preschool wheeze on families' lives, including high levels of worry and limiting capacity for work and travel. Barriers to effective management of preschool wheeze included inconsistent terminologies and diagnostic uncertainty alongside limited education and management support. Other barriers included parental concerns about medications, delayed investigations and challenges with accessing specialist care. Parents were in favour of performing investigations to guide treatment pathways.

Conclusion: Parents' views highlight the problem of diagnosing and treating preschool wheeze at multiple system levels. To improve management and ensure that services for children with preschool wheeze are effective, there is an urgent need for consistent terminology, a unified approach to guide investigations and treatments and for upskilling healthcare professionals in primary and secondary care.

Background: Understanding why children die is important for grieving parents and for informing system improvements aimed at prevention and future care. Many countries have child death review (CDR) process, but little is known about how best to engage parents. The aim of this study was to use experience-based co-design to create a toolkit to support parental involvement in CDR.

Methods: A survey of English paediatric intensive care units (PICUs) and palliative care services explored practices and identified a diverse sample of sites for professional interviews. Bereaved parents were recruited through charities, hospitals and social media. Semistructured interviews were held with parents and professionals followed by co-design workshops to develop the toolkit.

Results: There were 29 survey responses, 13 out of 21 from PICUs and 16 out of 34 from palliative care.21 multidisciplinary healthcare professionals were interviewed.23 bereaved parents of children who died aged 0-18 years in 2021-2022, either during hospital admission or under palliative care were, interviewed.10 parents and 23 professionals participated in co-design meetings. Key emotional touchpoints identified from parents' experiences were: becoming aware of CDR meetings, being asked for input, knowing the date and receiving feedback. All agreed on the importance of involving parents, with clear communication, and need for resources and training for key workers.The toolkit includes training videos, a standardised pathway including template letters, feedback form, easy-read leaflet and an animation explaining the importance of involving parents.

Conclusions: Co-design has successfully supported the development of a toolkit of resources in a sensitive area. It required considerable support from bereavement support organisations and researchers. Future evaluation is required.
