Increased fetal epicardial fat thickness: A novel ultrasound marker for altered fetal metabolism in diabetic pregnancies.

OBJECTIVE: To evaluate whether fetal epicardial fat thickness (EFT) differs in diabetic and nondiabetic pregnant women. METHODS: Retrospective case-control study of pregnancies between 24 and 36 weeks complicated by preexisting (PDM) or gestational (GDM) diabetes mellitus, matched one to one with controls for body mass index and gestational age (GA). Epicardial fat was identified as the hypoechogenic area between myocardium and visceral pericardium over the right ventricle and its thickness was measured by a single observer blinded to clinical condition and outcomes. A linear regression analysis was performed to assess the relationship between GA and EFT, and regression lines were compared between diabetics and controls. RESULTS: 53 PDM and 53 GDM pregnant women were matched with controls. With the exception of maternal age, the demographics were similar among groups. EFT increased significantly with advancing gestation in both diabetics and controls (P < 0.0001) and was significantly greater in diabetics than in controls (P < 0.0001). The best fit lines were different between diabetics (EFT = 0.05 × GA + 0.07 mm; R2 = 0.70) and controls (EFT = 0.07 × GA + 0.04 mm; R2 = 0.93) (P < 0.0001). CONCLUSION: Fetal EFT was greater in diabetics than in nondiabetics, and even greater in pregestational diabetics. EFT maybe an additional and/or earlier marker to identify early changes in fetal metabolism before accelerated fetal growth and polyhydramnios is apparent.

Prediction of maternal near-miss in placenta previa: a retrospective analysis from a tertiary center in Ankara, Turkey.

AIM: To determine risk factors for severe complications during and after cesarean delivery (CD) in placenta previa (PP). METHODS: We reviewed retrospectively collected data from women with PP who underwent CD during a 6-year study period. We identified the complicated group based on the modified WHO near-miss criteria. Complicated and noncomplicated groups were compared considering clinical, laboratory, and sonographic features. RESULTS: Thirty-seven of 256 cases classified as near miss consisting of 14 peripartum hysterectomies, 12 uterine balloon placements, 10 great artery ligations, and four B-lynch suture placement procedures without maternal mortality. Perioperative complications included surgical wound infections (n = 5), bladder injury (n = 4), pelvic abscess (n = 1), and uterine rupture (n = 1). Logistic regression analyses demonstrated following features to be associated with maternal near miss in PP: (1) coexistent abruption (aOR 13.2, 95% CI 5.8-75.3), (2) morbidly adherent placenta (aOR 11.92, 95% CI 3.24-43.82), (3) number of hospitalizations for vaginal bleeding (≥3) (aOR 8.88, 95% CI 3.32-26.69), and (4) transvaginal cervical length (CL) measurement <10th percentile (aOR 5.5, 95% CI 2.1-15.4). CONCLUSION: Short cervical length, recurrent vaginal bleeding, morbidly adherent placenta, and concurrent placental abruption are independent predictors for subsequent severe maternal morbidity in PP cases. Early identification of these risk factors during PP follow-up may improve maternal outcome.
