Prepregnancy BMI was calculated from self-reported height and weight on birth certificates. Obesity was defined as BMI ≥30.0 kg/m2 for all groups except Asian mothers, for whom BMI ≥25.0 kg/m2 was applied per established ethnicity-specific metabolic risk thresholds.Results: By 2024, normal weight prevalence had fallen below 50 % for all racial and ethnic groups except Asian mothers, who nonetheless demonstrated the steepest downward trajectory. Obesity prevalence increased steadily across all groups while normal weight declined universally. Non-Hispanic Native Hawaiian or Other Pacific Islander mothers had the highest absolute obesity prevalence at 51.6 %. Applying ethnicity-appropriate thresholds, obesity among Asian mothers reached 41.4 % - exceeding Non-Hispanic White and Hispanic mothers - representing the largest relative increase between 2016 and 2024.Conclusions: Between 2016 and 2024, the U.S. obstetric population experienced broad metabolic deterioration characterized by rising obesity and erosion of normal weight as the normative baseline at pregnancy entry. Ethnicity-specific BMI thresholds reveal Asian mothers as a rapidly emerging high-risk population, underscoring the need for system-level interventions and recalibrated preconception metabolic strategies.","PeriodicalId":16704,"journal":{"name":"Journal of Perinatal Medicine","volume":" ","pages":"679-686"},"PeriodicalIF":1.3,"publicationDate":"2026-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146227146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study objective was to determine the impact of maternal Crohn's disease on maternal and neonatal adverse outcomes.Methods: A retrospective cohort study was performed using the Healthcare Cost and Utilization Project-National Inpatient Sample from the United States. International Classification of Diseases, 10th edition (ICD-10) codes were used to identify individuals who delivered between 2016 and 2021, and then those with Crohn's disease were identified (ICD-10 code K50). The effect of Crohn's disease on pregnancy was estimated using multivariable logistic regression adjusted for baseline maternal characteristics.Results: There were 4,337,612 births between 2016 and 2021, of which 5,671 were associated with maternal Crohn's disease, for an overall period prevalence of 13.1/10,000 births. There was an upward trend in prevalence from 10.2/10,000 deliveries in 2016 to 15.6/10,000 deliveries in 2021 (p<0.0001). Individuals with Crohn's disease were at increased risk of preeclampsia (odds ratio 1.6, 95 % CI 1.4-1.7), chorioamnionitis (1.3, 1.1-1.5), placental abruption (1.4, 1.1-1.7), instrumental delivery (1.3, 1.1-1.4), cesarean delivery (1.6, 1.5-1.7), postpartum hemorrhage (1.3, 1.2-1.5), sepsis (2.0, 1.5-2.7), and venous thromboembolic events (2.1, 1.1-3.8). Neonates born to these mothers were more likely to be premature (1.6, 1.5-1.7), suffer from congenital anomalies (1.5, 1.2-1.8) and intrauterine growth restriction (1.7, 1.5-1.9).Conclusions: Crohn's disease in pregnancy was associated with adverse maternal and neonatal outcomes. Pregnant patients with Crohn's disease should therefore be closely monitored throughout their pregnancy to minimize these adverse outcomes.","PeriodicalId":16704,"journal":{"name":"Journal of Perinatal Medicine","volume":" ","pages":"744-751"},"PeriodicalIF":1.3,"publicationDate":"2026-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146201959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reference values were established for 25 heart rate indices. Nearly all heart rate indices were significantly influenced by gestational age, postnatal age and sex. Baseline heart rate decreased with gestational age, increased with postnatal age and was higher in females. Heart rate standard deviation increased with gestational age and postnatal age and was lower in female. Inclusion of birth weight significantly improved model fit for all HRV indices.Conclusions: This study highlights the importance of considering gestational and postnatal age, sex and birth weight when interpreting neonatal heart rate frequency and variability in preterm neonates. These findings support the need for personalized approaches for neonatal monitoring and interpretation. Future research should validate these values in larger, more diverse populations, including additional clinical factors such as neonatal complications and medication administration, to determine their clinical relevance.","PeriodicalId":16704,"journal":{"name":"Journal of Perinatal Medicine","volume":" ","pages":"778-787"},"PeriodicalIF":1.3,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146086032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Temporal changes in incidence were quantified using the estimated annual percentage change (EAPC). Correlations between incidence and SDI were analysed.Results: Globally, maternal haemorrhage cases declined slightly from 14.1 million in 1990 to 13.9 million in 2021 (EAPC = -1.03). The incidence rate decreased from 1,056.09 to 714.00 per 100,000 women. Marked declines were noted in age groups 15-19 years (EAPC = -1.48), 20-24 years (EAPC = -1.39) and 45-49 years (EAPC = -2.46). The steepest reductions occurred in low-middle SDI regions (EAPC = -2.13), while some high-SDI regions (e.g., Eastern Europe) experienced modest increases. Sub-Saharan Africa remained the region with the highest incidence (>1,000 per 100,000). A significant negative correlation was observed between SDI and maternal haemorrhage incidence.Conclusions: Although global incidence of maternal haemorrhage in women of reproductive age has declined over the past three decades, substantial regional and sociodemographic disparities persist. The findings highlight that improvements in obstetric and public health systems have had global impact, yet targeted efforts are needed in low-SDI regions to achieve maternal health equity.","PeriodicalId":16704,"journal":{"name":"Journal of Perinatal Medicine","volume":" ","pages":"724-733"},"PeriodicalIF":1.3,"publicationDate":"2026-02-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146086066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were categorized into three groups (TTTS, sIUGR, and uncomplicated). Clinical and laboratory data were analyzed. Significant predictors were identified via random forest algorithm and multivariate logistic regression.

TTTS was confirmed as an independent risk factor (OR=2.846, p<0.05). Gestational age was the strongest predictor. Four risk models showed AUCs of 0.796-0.919.
