RESUMO
(1) Background: Breastfeeding duration may be reduced in women with type 2 diabetes. Delayed secretory activation (SA) is associated with poorer breastfeeding outcomes; however, no prior studies have examined SA in women with type 2 diabetes. This pilot study aimed to assess SA in women with type 2 diabetes by assessing breastmilk constituents. Secondary aims were to assess breastfeeding rates postpartum, and contributory factors. (2) Methods: A prospective cohort of pregnant women with type 2 diabetes (n = 18) and two control groups with age- and parity-matched nondiabetic pregnant women (body mass index (BMI)) matched (n = 18) or normal-range BMI (n = 18)) were recruited. Breastmilk constituents (citrate, lactose, protein, and fat) were measured twice daily for 5 days postpartum and compared between groups. Associations between peripartum variables, breastmilk constituents, and breastfeeding at 4 months postpartum were explored. (3) Results: Women with type 2 diabetes had a slower increase in breastmilk citrate concentration postpartum, indicative of delayed SA, compared to both control groups. Higher predelivery insulin doses in women with type 2 diabetes were associated with increasing time to SA. Both women with type 2 diabetes and BMI-matched controls were less likely to fully breastfeed at 4 months, compared with normal-BMI controls. (4) Conclusion: SA is delayed in women with type 2 diabetes when compared to BMI-matched and normal-BMI women. Women with type 2 diabetes are less likely to fully breastfeed, at hospital discharge and by 4 months postpartum, compared to women with normal-BMI.

AIMS: Some guidelines recommend altering glycemic targets in gestational diabetes mellitus (GDM) based on ultrasound measurements of fetal growth, but the impact on outcomes in clinical practice is unknown. The aim of this study was to compare the effects of ultrasound-guided and non-ultrasound-guided management on neonatal outcomes. METHODS: This was a retrospective, observational study of a random sample of women with GDM and their infants. Outcomes were compared between those who had GDM management tailored according to fetal growth and those who did not. RESULTS: In the sample of 221 women, 134 had documentation of ultrasound-guided management while 87 did not. There was no significant difference in size-for-gestational age between groups. Fewer neonates in the ultrasound-guided management group were admitted to the Special Care or Intensive Care Nursery (29.1% vs. 48.3%, P = 0.004), had a prolonged hospital stay (3.7% vs. 13.8%, P = 0.006), or had hypoglycemia after birth (42.5% vs. 56.3%, P = 0.045). The reduction in admission rates and prolonged hospital stays remained significant after controlling for confounding variables. CONCLUSIONS: Ultrasound-guided management was independently associated with improvements in some neonatal outcomes.

This is the full version of the Australasian Diabetes in Pregnancy Society (ADIPS) 2020 guideline for pre-existing diabetes and pregnancy. The guideline encompasses the management of women with pre-existing type 1 diabetes and type 2 diabetes in relation to pregnancy, including preconception, antepartum, intrapartum and postpartum care. The management of women with monogenic diabetes or cystic fibrosis-related diabetes in relation to pregnancy is also discussed.

CONTEXT: Metyrapone is an inhibitor of endogenous adrenal corticosteroid synthesis, which has been proven to be a viable option in controlling maternal serum cortisol concentrations during pregnancy. The infant exposure to maternally ingested metyrapone through breast milk is, however, largely unknown. CASE DESCRIPTION: We report the excretion of metyrapone into breast milk and subsequent infant exposure from a lactating woman on 250 mg of metyrapone three times daily. Due to limited supply of breast milk, the infant was fed â¼50% breast milk and 50% formula. At steady state, the average concentrations in the studied breast milk and absolute and relative infant doses were 176 µg/L, 26.45 µg/kg/d, and 0.7%, respectively, for metyrapone, and 310 µg/L, 46.52 µg/kg/d, and 1.21% for its active metabolite metyrapol. The breastfed infant was found to have a plasma metyrapone concentration of 0.05 µg/L, with no evidence of disruption to his adrenocortical axis biochemically. CONCLUSION: These findings indicate that maternal metyrapone use during breastfeeding did not pose a notable risk to this breastfed infant. The infants' exposure to metyrapone was further minimized by avoiding nursing for 2 to 3 hours after each metyrapone dose.
RESUMO
Context: Primary hyperparathyroidism (PHPT) in pregnancy has historically been associated with substantial maternofetal morbidity and mortality rates. The optimal treatment and timing of surgical intervention in pregnancy remain contested. Objective: To compare maternofetal outcomes of medically and surgically treated patients with PHPT in pregnancy. Design: Retrospective chart review. Setting: Quaternary referral hospital. Patients: Women with PHPT in pregnancy treated between 1 January 2000 and 31 December 2015. Interventions: Medical therapy or parathyroid surgery. Main Outcomes Measured: Timing of diagnosis; maternal corrected serum calcium concentrations; gestation, indication and mode of delivery; complications attributable to PHPT; birth weight; and admission to the neonatal intensive care unit (NICU). Results: Twenty-two pregnancies were managed medically, and six patients underwent parathyroidectomy in pregnancy (five in trimester 2, and one at 32 weeks gestation). Most patients treated medically either had a corrected serum calcium concentration <2.85 mmol/L in early pregnancy or had PHPT diagnosed in trimester 3. Of viable medically managed pregnancies, 30% were complicated by preeclampsia, and preterm delivery occurred in 66% of this group. All preterm neonates required admission to the NICU for complications related to prematurity. All surgically treated patients delivered their babies at term, and there were no complications of parathyroid surgery. Conclusion: Maternofetal outcomes have improved relative to that reported in early medical literature in patients treated medically and surgically, but the rates of preeclampsia and preterm delivery were higher in medically treated patients. The study was limited by its retrospective design and small sample sizes.
