Summary Objective: Mueller-Hillis maneuver (MHM) and angle of progression (AOP) measured by transperineal ultrasound have been used to assess fetal head descent during the second stage of labor. We aimed to assess whether AOP correlates with MHM in the second stage of labor. Method: A prospective observational study including women with singleton pregnancy in the second stage of labor was performed. The AOP was measured immediately after the Mueller-Hillis maneuver. A receiver-operating characteristics (ROC) curve analysis was performed to determine the best discriminatory AOP cut-off for the

The angle of progression (AoP) for assessing fetal head (FH) descent during labor is measured from the standard plane of transperineal ultrasound images as the angle between a line through the long axis of pubic symphysis (PS) and a second line from the right end of PS tangentially to the contour of the FH. This paper presents a multitask network with a shared feature encoder and three task-special decoders for standard plane recognition (Task1), image segmentation (Task2) of PS and FH, and endpoint detection (Task3) of PS. Based on the segmented FH and two endpoints of PS from standard plane

Objective: The objective of the study was to assess whether the measurement of the angle of progression in nulliparous women in labour can predict the mode of delivery. Methods: This prospective observational study was conducted at Benazir Bhutto Hospital, Rawalpindi Medical University from 16th February to 25th March 2024. Nulliparous pregnant women in the active first stage of labour with singleton pregnancy and cephalic presentation were included in the study after taking informed consent. The angle of progression (AOP) was measured by trans-perineal ultrasound using the curvilinear probe.

The transperineal ultrasound (TPU) value of the angle of progression (AOP) during fetal head engagement, at station 0, is a critical cut-off for current obstetrical practice, especially when intrapartum instrumental interventions are required. Still, controversial measurements were reported in previous high resolution imagistic studies. Our TPU and direct “gold-standard” magnetic resonance (MRI) measurements confirm that station 0 corresponds to a 120° AOP, concordantly. Based on these findings, the fact that an AOP of 120° or greater was previously strongly associated with vaginal delivery ma

Introduction: Numerous studies have shown that clinical evaluation in labor is not very accurate, therefore ultrasound is one of the instruments that can give us a more objective assessment than the clinical evaluation. Objectives: In this study, we investigate the magnitude of the angle of progression (AoP) at the second stage of labor in fetuses with cephalic presentation and its relation to spontaneous vaginal delivery. Patients and Methods: In this cross-sectional study, we measured the AoP using trans-perineal sonography in the 2nd stage of the labor and compared AoP in normal vaginal del

Background: As a multifactorial disease glaucoma may be associated with pressure-dependent and -independent factors. Ocular hypertension (OHT) may develop into primary open angle glaucoma (POAG) for many patients. We compared groups with OHT and POAG for pressure-dependent and -independent risk factors. A high prevalence of any factor(s) could indicate a contribution to progression from OHT to POAG. Method: A sample of patients with POAG (n 438) and with OHT (n 301) were selected from those attending a tertiary referral private glaucoma practice, and data were collected regarding age and intr

Using a sequential MRI series, spinal curves of adolescent patients with AIS were assessed in a level-wise manner for vertebral body wedge angle, vertebral body height, axial vertebral rotation and kyphosis. These measured values were then compared to the same parameters observed in a sequential MRI series of an adolescent non-scoliotic population.

The study of joint morphology can help us to understand the risk factors for osteoarthritis (OA), how it progresses, and aids in developing imaging biomarkers for study of the disease. OA results in gross structural changes in affected joints. Growth of osteophytes, deformation of joint components, and loss of joint space where cartilage has broken down are all characteristics of the disorder. Certain bone shapes as well as malalignment predispose people to future OA, or may be a marker for early OA.

Abstract The addition of a trailing edge flap is an effective way to enhance the lift generated by marine rudders. This is achieved through camber being introduced into the foil section when the flap is deflected. But the strong curvature in the flow around the flap’s leading edge makes it prone to early flow separation and increased drag. Leading-edge tubercles offer a means to control flow separation whilst improving lifting performance at post-stall angles of attack (AOA). Therefore, this study aims to investigate the tubercle leading edge’s (TLE) ability to improve the hydrodynamic perform

While much of the fi eld of architecture claims to be concerned with the mounting effects of climate change, its tools for combating it are limited. Important gains have been made in raising minimum performance standards, developing alternative materials, and voicing support of progressive policies, but these gains are insufficient. In the face of unprecedented warming and its demonstrated spillover effects, architecture must leverage every possible angle in pursuit of a viable future, including those that capture the imagination. This project seeks to forge new relationships between architect

Abstract The surface profile wear and the resulting third-body layer accumulation are investigated on the Virginia Tech-Federal Railroad Administration Roller Rig (VT-FRA Roller Rig), using a high-precision 3D laser profiler by Keyence. It is observed that the wheel surface gradually wears and the fine worn material accumulates on the running surfaces. It is further observed that with the progression of the wear and accumulation of a powder-like material at running surface, a preocular change in wheel-rail traction occurs. The first step in exploring the physics of the changes in traction is q

The Parowan 7.5' quadrangle is centered around the City of Parowan at the eastern margin of the Basin and Range Province in Iron County, southwestern Utah. The quadrangle covers part of the northwestern flank of the Markagunt Plateau and part of the adjacent Parowan Valley. Interstate 15 crosses the northwestern corner of the map area. Parowan Creek and its tributaries have carved deep canyons into the Markagunt Plateau, exposing a succession of sedimentary and volcanic rocks ranging in age from Late Cretaceous to Middle Pleistocene. The modern landscape is dominated by northeast-southwest-tre
