Effect of Targeted Aspirin Administration Based on First Trimester Combined Screening for Preeclampsia on Preterm Birth: An Interrupted Time Series Analysis

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objectives To assess the effect of an aspirin intervention program on preterm birth (PTB) rates in women identified as high‐risk for preterm preeclampsia in the first‐trimester screening. Design This is a retrospective study evaluating the impact of the intervention program on preterm birth using interrupted time series analysis (ITSA) with an

Dirty-Appearing White Matter in the Brain is Associated with Altered Cerebrospinal Fluid Pulsatility and Hypertension in Individuals without Neurologic Disease. [PDF]

, 2015
Aging of the healthy brain is characterized by focal or nonfocal white matter (WM) signal abnormality (SA) changes, which are typically detected as leukoaraiosis (LA). Hypertension is a risk factor for WM lesion formation. This study investigated whether

The Performance of Selective Screening Ultrasound to Detect the Small‐for‐Gestational‐Age Foetus: A Prospective Cohort Study Nested Within the DESiGN Randomised Control Trial

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective Evidence on the performance of foetal growth ultrasound parameters to detect the Small‐for‐Gestational‐Age (SGA) foetus for a selective cohort is limited. We report the performance of estimated foetal weight under the 10th percentile (EFW < 10th) at the last selective screening ultrasound to detect SGA based on gestational age of ...

Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]

, 2010
The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...
