The development of an arrhythmia is associated with a heightened risk of subsequent failure of the Fontan circulation.

Background To determine the prevalence and outcomes of intrahepatic cholestasis of pregnancy. Methods A review comparing intrahepatic cholestasis of pregnancy pregnancies to all other pregnancies in three tertiary care Australian hospitals over a 36-month period. Results There were 43,876 pregnancies. The prevalence of intrahepatic cholestasis of pregnancies ( n = 319) was 0.7%. There were differences between intrahepatic cholestasis of pregnancy and non-intrahepatic cholestasis of pregnancy mothers including higher prevalence of South Asian (22.6% versus 3.1%, p < 0.001), Indigenous Australian (3.8% versus 1.8%, p < 0.05), and Asian ethnicity (8.4% versus 5.7%, p < 0.05), mothers with a body mass index >35 kg/m2 (10.6% versus 5.5%, p < 0.001), those with diabetes mellitus (25.7% versus 9.8%, p < 0.001), and those with twin births (8.7% versus 2.2%, p < 0.001). The primary clinical outcomes of intrahepatic cholestasis of pregnancy included a median gestational age at delivery of 36.4 (SE 0.09) weeks compared to 38.6 (SE 0.01) weeks (p < 0.001), a lower birth weight (3.12 (SE 0.03) versus 3.31 kg (SE 0.03), p < 0.001), and an increase in special care nursery admissions (44.5% versus 15.3%, p < 0.001). Conclusion Treated intrahepatic cholestasis of pregnancy in the population described here had similar mortality outcomes although increased special care nursery admission as compared to the general population.

ObjectiveWe asked whether 60 compared with 240 min observation is sufficiently informative and safe for pregnancy day assessment (PDAC) of suspected pre-eclampsia (PE).DesignA retrospective study of 209 pregnant women (475 PDAC assessments, 6 months) with routinely collected blood pressure (BP), symptom and laboratory information. We proposed a 60 min screening algorithm comprising: absence of symptoms, normal laboratory parameters and ≤1high-BP reading (systolic blood pressure, SBP 140 mm Hg or higher or diastolic blood pressure, DBP 90 mm Hg or higher). We also evaluated two less inclusive screening algorithms. We determined short-term outcomes (within 4 h): severe hypertension, proteinuric hypertension and pregnancy-induced hypertension, as well as long-term outcome: PE-related diagnoses up to the early puerperium. We assessed performance of alternate screening algorithms performance using 2×2 tables.Results1 in 3 women met all screen negative criteria at 1 h. Their risk of hypertension requiring treatment in the next 3 h was 1.8% and of failing to diagnose proteinuric hypertensive PE at 4 h was 5.1%. If BP triggers were 5 mm Hg lower, 1 in 6 women would be screen-negative of whom 1.1% subsequently develops treatment-requiring hypertension and 4.5% demonstrate short-term proteinuric hypertension. We present sensitivity, specificity, negative and positive likelihood ratios for alternate screening algorithms.ConclusionsWe endorse further research into the safest screening test where women are considered for discharge after 60 min. Safety, patient and staff satisfaction should be assessed prospectively. Any screening test should be used in conjunction with good clinical care to minimise maternal and perinatal hazards of PE.
