Objective: This study investigates the cost effectiveness of gestational diabetes mellitus screening using the new International Association of Diabetes in Pregnancy Study Group (IADPSG) guidelines.
Study Design: A decision analytic model was built comparing routine screening with the 2-hour (2h) oral glucose tolerance test (OGTT) vs the 1-hour glucose challenge test. All probabilities, costs, and benefits were derived from the literature. Base case, sensitivity analyses, and a Monte Carlo simulation were performed.
Results: Screening with the 2h OGTT was more expensive, more effective, and cost effective at $61,503/quality-adjusted life year. In a 1-way sensitivity analysis, the more inclusive IADPSG diagnostic approach remained cost effective as long as an additional 2.0% or more of patients were diagnosed and treated for gestational diabetes mellitus.
Conclusion: Screening at 24-28 weeks' gestational age under the new IADPSG guidelines with the 2h OGTT is expensive but cost effective in improving maternal and neonatal outcomes. How the health care system will provide expanded care to this group of women will need to be examined.

Is Polyhexamethylene Guanidine and Oligo(2-(2-Ethoxy) Ethoxyethyl Guanidium Chloride Exposure Related to Gestational Diabetes?

This study aims to investigate the association between exposure to toxic indoor chemicals, specifically polyhexamethylene guanidine (PHMG) and oligo(2-(2-ethoxy) ethoxyethyl guanidinium) chloride (PGH), used in humidifier disinfectants, and gestational diabetes mellitus (GDM). We confirmed pregnancy from 2003 to 2017 and identified GDM by linking a cohort of claimants who reported exposure to PHMG/PGH with National Health Insurance Service data. The GDM incidence was calculated, and PHMG/PGH exposure characteristics-exposure status, the humidifier's distance/location, and exposure duration/hours-were investigated.

Background: Pregnancy is a unique stage of the life course characterized by trade-offs between the nutritional, immune, and metabolic needs of the mother and fetus. The Camden Study was originally initiated to examine nutritional status, growth, and birth outcomes in adolescent pregnancies and expanded to study dietary and molecular predictors of pregnancy complications and birth outcomes in young women.
Methods: From 1985-2006, 4765 pregnant participants aged 12 years and older were recruited from Camden, NJ, one of the poorest cities in the US.

Women diagnosed with gestational diabetes mellitus (GDM) face a significantly heightened risk of developing type 2 diabetes mellitus (T2DM) later in life. Breastfeeding (BF) has been identified as a potential strategy to delay or prevent T2DM; however, women with GDM often encounter barriers in initiating and maintaining adequate BF practices compared to those with uncomplicated pregnancies. This paradox prompts an exploration into the causes of these BF challenges and considers the possibility of reverse causation: Does prolonged and intensive BF mitigate the risk of subsequent glucose dysregulation and T2DM? Alternatively, do women with compromised insulin secretion and sensitivity, who are predisposed to T2DM, struggle to sustain intensive BF practices? This narrative review aims to explore the interplay between GDM, BF, and T2DM development by examining the different factors that present BF challenges among women with GDM.

Background/objectives: The prevalence of gestational diabetes mellitus (GDM) is increasing, and GDM poses health risks for both mothers and newborns. This study investigated the association between GDM and two biomarkers, osteopontin (OPN) and betatrophin (ANGPTL8).
Methods: This study involved face-to-face interviews with 165 participants-81 in the GDM group and 84 in the control group-to gather maternal-newborn data.
