AI Article Synopsis
- The study analyzes perinatal outcomes in Samoan and Caucasian populations, focusing on macrosomic (over 4500 g) and low birth weight (under 2500 g) births.
- The findings reveal that macrosomia is more common and low birth weight is less common among Samoan neonates, with higher perinatal mortality and morbidity rates in the Samoan population for macrosomic births.
- The conclusion suggests that these differences may be linked to the unique anthropometric characteristics of the Samoan population.
Article Abstract
Background: To assess the perinatal morbidity and mortality of macrosomic (>4500 g) and low birth weight (LBW) (<2500 g) neonates in a Pacific Islander population (PIP) from Samoa compared to a Caucasian population (CP).
Methods: Case-control study. Clinical data were extracted by chart review.
Results: In 3166 (PIP) and 2101 (CP) deliveries, macrosomia was more prevalent and LBW less prevalent in the PIP [76/3166 (2.4 %) vs. 21/2101 (0.9 %); p < 0.0001 and 149/3166 (4.7 %) vs. 163/2101 (7.7 %); p < 0.0001, respectively]. Among macrosomic neonates, perinatal mortality and composite severe neonatal morbidity (CNM) were higher in the PIP compared to the CP [2/76 (3 %) vs. 0/21 (0 %) and 6/76 (7 %) vs. 1/21 (4 %), respectively]. Among LBW neonates, mortality, but not CNM, was significantly higher in the PIP [16/149 (7 %) vs. 2/163 (1 %), p < 0.0001 and 10/149 (6 %) vs. 5/163 (3 %), p = 0.2, respectively]. The proportion of macrosomic neonates transferred to the Neonatal Intensive Care Unit was significantly higher in the PIP [50/76 (65 %) vs. 0/21 (0 %), p < 0.0001]. Age, body mass index, and delivery mode did not independently predict CNM.
Conclusion: Samoan women have higher rates of macrosomia and lower rates of LBW compared to Caucasians, suggesting an anthropomorphic basis of this phenomenon.

In social animals, group dynamics profoundly influence collective behaviours, vital in processes like information sharing and predator vigilance. Disentangling the causes of individual-level variation in social behaviours is crucial for understanding the evolution of sociality. This requires the estimation of the genetic and environmental basis of these behaviours, which is challenging in uncontrolled wild populations.

Objective: Cesarean sections (CS) are among the most performed surgical procedures in the world. Small variations in surgical techniques could have a significant impact on a global scale, for example, in postoperative complications. In the present study we aimed to observe and audit every single step used during first time CS.

Introduction: Induction of labor is a common procedure, and in Denmark, approximately one in four vaginal deliveries are induced. The association between induction and maternal postpartum infections such as endometritis, surgical site infection after cesarean section, urinary tract infection, and sepsis has been sparsely investigated. Our objective was to investigate the association between induction of labor and risk of maternal postpartum infection and to identify potential risk factors for infection.

Introduction: Home birth is described as a delivery that takes place at home without the presence of a skilled birth attendant. In 2017, nearly 295,000 mothers died from various pregnancy and childbirth-related problems, accounting for approximately 810 maternal deaths per day. Therefore, this study aims to investigate the spatial distributions of home birth and associated factors in Ethiopia using the Performance Monitoring for Action Survey (PMAS) 2019) to get information that helps to take geographic-based interventions and can assist health planners and policymakers in developing particular measures to reduce home deliveries.

Objective: To assess the implementation of the "10 Steps for Successful Breastfeeding" and explore associations with any Breastfeeding (BF) and Exclusive Breastfeeding (EBF) initiation and continuation.
Methods: Implementation of the 10 Steps was assessed based on a consecutive sample of 568 mothers' self-reported experience across all public ( = 5) and 29 (of 35) private maternity clinics using the WHO/UNICEF BFHI questionnaire (Section 4) within the first 24-48 h after birth. BF and EBF were estimated within 48 h after birth as well as at 1st, 4th and 6th month based on a self-reported current status method.
