Development and external validation of deep learning models for spontaneous preterm birth prediction from mid-trimester cervical ultrasound

This study developed and externally validated deep learning and multimodal models for predicting spontaneous preterm birth using mid-trimester cervical ultrasound, finding that while internal performance was modest, external validation yielded poor results likely due to the heterogeneity of preterm birth, suggesting a need for subtype-specific modeling and additional biomarkers.

Comparing measured and calculated blood loss after a caesarean birth

This secondary analysis of the I'M WOMAN trial data reveals that while measured and calculated blood loss methods show weak correlation and calculated loss overestimates high-volume thresholds, measured blood loss demonstrates superior predictive ability for severe maternal outcomes, though calculated loss remains a viable objective alternative when direct measurement is not feasible.

From Christmas sex to winter intimacy: three decades of birth seasonality, sex ratio dynamics, and fertility change in South Africa, 1994-2024

This study analyzes South African birth data from 1994 to 2024 to reveal a significant shift from Christmas-season to winter conceptions, a stress-induced dip and subsequent spike in the sex ratio linked to the 2021 pandemic mortality peak, and an accelerating decline in annual fertility rates reaching a 30-year low in 2024.
