Introduction: Human placental lactogen (hPL) is a placental hormone which, according to preclinical research, appears to have key metabolic roles in pregnancy. We aimed to examine pregnancy hPL levels in relation to maternal metabolic parameters and fetal outcomes within an ethnically diverse cohort at high metabolic risk. Design was an observational cohort study, nested within a randomized controlled trial.

Problem: Women with previous gestational diabetes mellitus (GDM) are at increased risk of type 2 diabetes (T2D).

Background: In Australia, GDM and T2D prevalence are particularly high among Indian and Chinese women. Attendance for recommended postpartum T2D screening is low.

Article Synopsis
  • The study investigates the global prevalence of polycystic ovary syndrome (PCOS) in adolescents, using two different diagnostic criteria: the old Rotterdam criteria and the updated International Evidence-based PCOS Guideline.
  • Out of 15,708 articles reviewed, 24 studies covering different world regions were included in the meta-analysis, which found PCOS prevalence to be 9.8% under the Rotterdam criteria and 6.3% under the new guidelines.
  • The findings suggest that the new guidelines may help prevent over-diagnosis by excluding certain criteria related to normal puberty, while still emphasizing the importance of monitoring adolescents with irregular cycles or signs of hyperandrogenism.

Introduction: Women with previous gestational diabetes mellitus (GDM) are at increased risk of type 2 diabetes (T2D). Guidelines recommend postnatal diabetes screening (oral glucose tolerance test or HbA1c) typically 6-12 weeks after birth, with screening maintained at regular intervals thereafter. Despite this, around half of women are not screened, representing a critical missed opportunity for early identification of prediabetes or type 2 diabetes.

During pregnancy, the fetoplacental unit is key in the pronounced physiological endocrine changes which support pregnancy, fetal development and survival, birth and lactation. In healthy women, pregnancy is characterized by changes in insulin sensitivity and increased maternal androgen levels. These are accompanied by a suite of mechanisms that support fetal growth, maintain glucose homeostasis and protect both mother and fetus from adverse effects of pregnancy induced insulin and androgen excess.

Aims: Racial and ethnic disparities exist in gestational diabetes prevalence and risk of subsequent type 2 diabetes mellitus (T2DM). Postpartum engagement in healthy behaviours is recommended for prevention and early detection of T2DM, yet uptake is low among women from diverse cultural backgrounds. Greater understanding of factors impacting postpartum health behaviours is needed.

Aims: Women with prior gestational diabetes have nearly 10 times the risk of developing type 2 diabetes. Postpartum screening for type 2 diabetes is recommended for early diagnosis and management, yet uptake is low. This work updates a previous systematic review and advances it through the application of the Theoretical Domains Framework (TDF) to synthesise personal-level factors impacting type 2 diabetes screening and the Capability, Opportunity, Motivation-Behaviour model (COM-B), to develop messaging recommendations for use in clinical practice and screening promotion interventions.

Objective: To investigate the origin and outcome in a cohort of male and female fetuses with intra-abdominal cysts, in order to provide recommendations on management and to improve prenatal counselling.

Methods: From 2002 to 2016, intra-abdominal cysts were detected by ultrasound in 158 fetuses. Cases with an umbilical vein varix were excluded.

Polycystic ovary syndrome (PCOS) is a common hormonal condition with reproductive, metabolic, and psychological sequelae. The Rotterdam Criteria are now internationally accepted, with different phenotypes recognized with varying clinical presentations and risk profiles. The complexity of the disorder, and the impact on quality of life, requires timely diagnosis, screening for complications and management strategies.
