Introduction Antenatal corticosteroids are widely used to prevent morbidity and mortality after preterm birth, but there are ongoing concerns about the possible risk of long‐term adverse effects, including perturbation of endocrine systems, with potential implications for reproduction. A small number of animal studies have suggested possible adverse effects on reproduction after antenatal exposure to corticosteroids, but there is a paucity of human data. Material and Methods This is a secondary cohort analysis of the 50‐year follow‐up of the Auckland Steroid Trial (1969–1974) comparing antenatal exposure to corticosteroids or placebo. Participants whose mothers took part in the placebo‐controlled randomized trial of antenatal corticosteroids completed a questionnaire reporting reproductive outcomes at 50 years of age. The main outcome was at least one pregnancy ≥20 weeks or fathered at least one pregnancy ≥20 weeks. Additional outcomes included a number of pregnancies or fathered pregnancies ≥20 weeks, outcomes relating to female reproductive lifespan (including age at menarche and menopause), and outcomes relating to their offspring (including birthweight and gestation). Results Of 917 eligible participants, 415 (45% of eligible) completed the questionnaire at a mean (SD) age of 49.3 (1.0) years. The proportion of participants who had experienced at least one pregnancy ≥20 weeks or fathered at least one pregnancy ≥20 weeks was similar in betamethasone and placebo‐exposed groups (163/217 [75%] vs. 136/190 [72%]; RR 1.08, (95% CI 0.95 to 1.22); p = 0.23). Participants exposed to betamethasone had a slightly higher number of pregnancies or fathered pregnancies ≥20 weeks compared to those exposed to placebo (mean 1.89 vs. 1.60; marginal mean difference 0.20, (95% CI 0.03–0.37); p = 0.03). Other outcomes, including female reproductive lifespan and offspring‐related outcomes, were similar in both randomized groups. There were also no differences in any outcomes between those born preterm and those born at term. Conclusions Antenatal exposure to corticosteroids appears to have no clinically important effect on reproductive outcomes to 50 years. Antenatal corticosteroids are recommended for preterm birth, but the effects on offspring reproduction are unknown. This 50‐year follow‐up of participants in a randomized trial found that exposure to antenatal corticosteroids does not appear to affect later reproduction.

Crohn Disease (CD) is a complex genetic disorder for which more than 140 genes have been identified using genome wide association studies (GWAS). However, the genetic architecture of the trait remains largely unknown. The recent development of machine learning (ML) approaches incited us to apply them to classify healthy and diseased people according to their genomic information. The Immunochip dataset containing 18,227 CD patients and 34,050 healthy controls enrolled and genotyped by the international Inflammatory Bowel Disease genetic consortium (IIBDGC) has been re-analyzed using a set of ML methods: penalized logistic regression (LR), gradient boosted trees (GBT) and artificial neural networks (NN). The main score used to compare the methods was the Area Under the ROC Curve (AUC) statistics. The impact of quality control (QC), imputing and coding methods on LR results showed that QC methods and imputation of missing genotypes may artificially increase the scores. At the opposite, neither the patient/control ratio nor marker preselection or coding strategies significantly affected the results. LR methods, including Lasso, Ridge and ElasticNet provided similar results with a maximum AUC of 0.80. GBT methods like XGBoost, LightGBM and CatBoost, together with dense NN with one or more hidden layers, provided similar AUC values, suggesting limited epistatic effects in the genetic architecture of the trait. ML methods detected near all the genetic variants previously identified by GWAS among the best predictors plus additional predictors with lower effects. The robustness and complementarity of the different methods are also studied. Compared to LR, non-linear models such as GBT or NN may provide robust complementary approaches to identify and classify genetic markers.

Jonathan Marchini and colleagues with the Ox-GSK consortium report a meta-analysis for smoking phenotypes from 20 studies including 41,150 individuals, confirming an association at the
CHRNA5
–
CHRNA3
locus on 15q25 to smoking quantity. They use imputation based on 1,000 Genomes Project Pilot 1 data to refine the association at this locus.
Smoking is a leading global cause of disease and mortality
1
. We established the Oxford-GlaxoSmithKline study (Ox-GSK) to perform a genome-wide meta-analysis of SNP association with smoking-related behavioral traits. Our final data set included 41,150 individuals drawn from 20 disease, population and control cohorts. Our analysis confirmed an effect on smoking quantity at a locus on 15q25 (
P
= 9.45 × 10
−19
) that includes
CHRNA5
,
CHRNA3
and
CHRNB4
, three genes encoding neuronal nicotinic acetylcholine receptor subunits. We used data from the 1000 Genomes project to investigate the region using imputation, which allowed for analysis of virtually all common SNPs in the region and offered a fivefold increase in marker density over HapMap2 (ref.
2
) as an imputation reference panel. Our fine-mapping approach identified a SNP showing the highest significance, rs55853698, located within the promoter region of
CHRNA5
. Conditional analysis also identified a secondary locus (rs6495308) in
CHRNA3
.

Family member and service provider experiences and perspectives of a digital surveillance and service navigation approach in multicultural context: a qualitative study in identifying the barriers and enablers to Watch Me Grow-Electronic (WMG-E) program with a culturally diverse community
2024
Background
Children and families from priority populations experienced significant psychosocial and mental health issues to the COVID-19 pandemic. Yet they also faced significant barriers to service access, particularly families from culturally and linguistically diverse (CALD) backgrounds. With most child and family health nurse clinics ceasing in-person consultations due to the pandemic, many children missed out on health and developmental checks. The aim of this study was to investigate the perspectives and experiences of family members and service providers from an urban, CALD community regarding the implementation of a digital, developmental surveillance, Watch Me Grow-Electronic (WMG-E) program.
Methods
Semi-structured interviews were conducted with 17 family members, service navigators, and service providers in a multicultural community in South Western Sydney, Australia. This qualitative study is an implementation evaluation which formed as part of a larger, two-site, randomised controlled trial of the WMG-E program. A reflexive thematic analysis approach, using inductive coding, was adopted to analyse the data.
Results
Participants highlighted the comprehensive and personalised support offered by existing child and family health services. The WMG-E was deemed beneficial because the weblink was easy and quick to use and it enabled access to a service navigator who support family access to relevant services. However, the WMG-E was problematic because of technology or language barriers, and it did not facilitate immediate clinician involvement when families completed the weblink.
Conclusions
Families and service providers in this qualitative study found that using WMG-E empowered parents and caregivers to access developmental screening and learn more about their child’s development and engage with relevant services. This beds down a new and innovative solution to the current service delivery gap and create mechanisms that can engage families currently not accessing services, and increases knowledge around navigating the health and social care services. Notwithstanding the issues that were raised by families and service providers, which include accessibility challenges for CALD communities, absence of clinical oversight during screening, and narrow scope of engagement with available services being offered, it is worth noting that improvements regarding these implementation factors must be considered and addressed in order to have longevity and sustainability of the program.
