A single obstetrician performed all the scans, and another obstetrician analyzed the acquired 2D images and 3D volumes, blinded to clinical assessments and labor outcome. Intraobserver repeatability and intermethod agreement between 2D and 3D methods were analyzed.\n\nResults The repeatability coefficient was +/- 4.1 mm in 2D acquisitions and +/- 1.7 mm in 3D acquisitions of fetal head-perineum distance. The intraclass correlation coefficients ( ICC) were 0.94 for 2D and 0.99 for 3D measurements. The angle of progression repeatability coefficients were +/- 6.7. using 2D and +/- 5.7. Epigenetics inhibitor using 3D ultrasound and ICCs were 0.91 and 0.94, respectively. The intermethod ICC for
fetal head-perineum distance in 2D vs 3D acquisitions was 0.95 and for angle of progression it was 0.93; the intermethod 95% limits of agreement were -5.8 mm to + 7.2 mm and -8.9. to + 13.7., respectively. Cohen’s
kappa for 2D vs 3D acquisitions BMN 673 price was 0.85 using 40 mm as a cut-off level for fetal head-perineum distance and 0.79 using 110. as cut-off level for angle of progression.\n\nConclusions For one ultrasound operator the intraobserver repeatability and agreement between 2D and 3D ultrasound methods in prolonged first stage of labor were good. Given that 2D methods are simpler to learn and can be analyzed quickly online, 2D equipment might therefore be preferred in the labor room. Copyright (C) 2012 ISUOG.

“The purpose of this study was to determine the effect of augmentative visual feedback training on auditory motor performance. Thirty-two healthy young participants used
facial surface electromyography (sEMG) to control a human machine interface (HMI) for which the output was vowel synthesis. An auditory-only (AO) group (n = 16) trained with auditory feedback alone and an auditory visual (AV) group (n = 16) trained with auditory feedback and progressively-removed ARN-509 visual feedback. Subjects participated in three training sessions and one testing session over 3 days. During the testing session they were given novel targets to test auditory motor generalization. We hypothesized that the auditory visual group would perform better on the novel set of targets than the group that trained with auditory feedback only. Analysis of variance on the percentage of total targets reached indicated a significant interaction between group and session: individuals in the AV group performed significantly better than those in the AO group during early training sessions (while using visual feedback), but no difference was seen between the two groups during later sessions. Results suggest that augmentative visual feedback during training does not improve auditory motor performance. (C) 2014 Elsevier B.V. All rights reserved.”
