Randomized Controlled TrialSwedish randomized controlled trial of cardiotocography only versus cardiotocography plus ST analysis of fetal electrocardiogram revisited: analysis of data according to standard versus modified intention-to-treat principle.
To undertake a renewed analysis of data from the previously published Swedish randomized controlled trial on intrapartum fetal monitoring with cardiotocography (CTG-only) vs. CTG plus ST analysis of fetal electrocardiogram (CTG+ST), using current standards of intention-to-treat (ITT) analysis and to compare the results with those of the modified ITT (mITT) and per protocol analyses. ⋯ Re-analysis of data according to the ITT principle showed that regardless of the method of analysis, the Swedish randomized controlled trial maintained its ability to demonstrate a significant reduction in metabolic acidosis rate when using CTG+ST analysis for fetal surveillance in labor.

Restless legs syndrome in pregnancy is a frequent disorder with a good prognosis.
The aim of this study was to assess the prevalence of restless legs syndrome in pregnancy. We distributed a questionnaire to 541 consecutive postpartum patients and received answers from 251 (46%) women. ⋯ There was no correlation between pregnancy-related restless legs syndrome and low hemoglobin levels in the first trimester, and the incidence of restless legs syndrome was not affected by use of iron supplementation. We conclude that in our population, restless legs syndrome in pregnancy is both frequent and transient, occurring in approximately one in three pregnancies and typically resolving within a few days after delivery.
