Perinatal Outcome and its Prediction Using Longitudinal Feto-Maternal Doppler Follow-Up in Late Onset Small for Gestational Age Fetuses - A Prospective Cohort Study.

PURPOSE: To describe the perinatal outcome of a prospective cohort of late-onset small-for-gestational-age (SGA) fetuses and to test adverse perinatal outcome (APO) prediction using Doppler measurements. METHODS: Singleton pregnancies from 32 weeks with suspicion of SGA (followed-up each 2 weeks) and randomly selected healthy controls at a university hospital were included. The whole SGA group was divided into the FGR subgroup or SGA percentile 3-10 subgroup. The following Doppler measurements were evaluated prospectively: umbilical artery (UA) pulsatility index (PI), middle cerebral artery (MCA) PI, cerebro-placental ratio (CPR), and mean uterine artery (mUtA) PI. APO was defined as arterial cord blood pH ≤ 7.15 and/or 5-minute Apgar ≤ 7 and/or emergency operative delivery and/or admission to the neonatal unit. Induction of labor was indicated according to a stage-based protocol. RESULTS: A total of 149 SGA and 143 control fetuses were included. The number of operative deliveries was similar between both groups (control: 29 %, SGA: 28 %), especially the cesarean delivery rate after the onset of labor (11 % vs. 10 %). Most SGA cases ended up in induction of labor (61 % vs. 31 %, p < 0.001). The areas under the curve (AUC) for APO prediction were similar using the last UA PI, MCA PI, CPR, and mUtA PI and barely reached 0.60. The AUC was best for the FGR subgroup, using the minimal CPR or maximum mUtA PI z-score of all longitudinal measurements (AUC = 0.63). CONCLUSION: SGA fetuses do not have a higher rate of operative delivery if managed according to a risk stratification protocol. Prediction of APO is best for SGA and FGR using the "worst" CPR or mUtA PI but it remains moderate.

Myocardial deformation analysis in late-onset small-for-gestational-age and growth-restricted fetuses using two-dimensional speckle tracking echocardiography: a prospective cohort study.

OBJECTIVES: An association between fetal growth restriction (FGR) and increased predisposition to cardiovascular disease (CVD) is suggested. The aim of this study was to evaluate subclinical signs of fetal cardiac remodeling in late-onset small-for-gestational-age (SGA) and growth-restricted fetuses using two-dimensional speckle tracking echocardiography (2D-STE). METHODS: This is a prospective cohort study, including 117 late-onset (≥32 weeks) SGA (birthweight≤10th centile) fetuses and 102 gestational age matched controls. A subgroup analysis was performed: FGR was defined based on either BW (0.05). Regarding global and segmental LPSS and LSR values of LV/RV, subgroup analysis revealed no significant difference between the FGR (n=81), SGA centile 3-10 (n=36) and control group. CONCLUSIONS: A mild degree of placental dysfunction seems not to influence myocardial deformation properties measured by 2D-STE.

[Endoscopic tunneling procedures in achalasia and gastroparesis]. / Endoskopische Tunnelungsverfahren bei Achalasie und Gastroparese.

Since the first publication of peroral endoscopic myotomy (POEM) by Haruhiro Inoue et al. in 2008 in Japan, various novel endoscopic procedures have been established, which are performed after iatrogenic creation of a submucosal tunnel as a "new space" 1. Through the artificially formed access in the tela submucosa, interventions in the muscular layer of the esophagus and stomach can be performed while carefully sparing the mucosal layer 2. These include, peroral myotomy of the esophageal muscle layer in patients with achalasia (POEM) and myotomy of the pylorus in patients with gastroparesis (antropyloromyotomy, G-POEM). Further indications include splitting of Zenker diverticulum in POEM technique ("Z-POEM") as well as the removal of subepithelial tumors (STER: submucosal tunneling, endoscopic resection). The long-term therapeutic success (with > 80 % response) of these innovative procedures has now been proven by controlled studies, especially in achalasia 2 3 4 5 6.
