Introduction of a new fetal examination protocol for on-field and clinical equine practice.

Theriogenology 2019 Feb 13;125:210-215. Epub 2018 Nov 13.

MTA-SZIE Large Animal Clinical Research Group, H-2225, Üllő, Hungary.

Prepartum fetal surveillance techniques have been widely used in both human and veterinary obstetrics, although these tests differ in their sensitivity for the assessment of fetal well-being. In equine reproduction, the 'gold standard' examination technique is the equine biophysical profile (EBP) described by Virginia Reef in 1995. Although this fetal assessment has many benefits, its accuracy, sensitivity and specificity have not been evaluated so far. Read More

Flexible proton density (PD) mapping using multi-contrast variable flip angle (VFA) data.

Neuroimage 2019 02 19;186:464-475. Epub 2018 Nov 19.

UCL Great Ormond Street Institute of Child Health, University College London, London, UK; EPSRC / Wellcome Centre for Medical Engineering, Biomedical Engineering, King's College, London, UK.

Quantitative proton density (PD) maps measure the amount of free water, which is important for non-invasive tissue characterization in pathology and across lifespan. PD mapping requires the estimation and subsequent removal of factors influencing the signal intensity other than PD. These factors include the T1, T2* relaxation effects, transmit field inhomogeneities, receiver coil sensitivity profile (RP) and the spatially invariant factor that is required to scale the data.

Ahmet A Baschat

Best Pract Res Clin Obstet Gynaecol 2018 May 1;49:53-65. Epub 2018 Mar 1.

Johns Hopkins Center for Fetal Therapy Department of Gynecology & Obstetrics Johns Hopkins University Baltimore, MD, 21287, USA. Electronic address:

A uniform approach to management of fetal growth restriction (FGR) improves outcome, prevents stillbirth, and allows appropriately timed delivery. An estimated fetal weight below the tenth percentile with coexisting abnormal umbilical artery (UA), middle cerebral artery (MCA), or cerebroplacental ratio Doppler index best identifies the small fetus requiring surveillance. Placental perfusion defects are more common earlier in gestation; accordingly, early-onset (≤32 weeks of gestation) and late-onset (>32 weeks) FGR differ in clinical phenotype. Read More

Principles of first trimester screening in the age of non-invasive prenatal diagnosis: screening for other major defects and pregnancy complications.

Arch Gynecol Obstet 2017 Oct 11;296(4):635-643. Epub 2017 Jul 11.

Department of Obstetrics and Gynaecology, University of Tuebingen, Calwerstrasse 7, 72076, Tübingen, Germany.

Purpose: First trimester risk assessment plays a major role in the contemporary pregnancy care. It has evolved significantly since its introduction in the 1990s when it essentially consisted of just the nuchal translucency measurement. Today, it involves the measurement of several biophysical and biochemical markers and can assess the risk for a wide array of major chromosomal and non-chromosomal defects as well as other pregnancy-related complications.

Correlation of Oxidative Stress Markers with Ultrasound and Cardiotocography Parameters with Hypertension Induced Pregnancy.

Acta Inform Med 2017 Mar;25(1):19-23

Clinic for Urology, University Clinical Centre of the Republic of Srpska, Banjaluka, Bosnia and Herzegovina.

Introduction: Pregnancy induced hypertension (PIH), especially preeclampsia, is a state of extremely increased oxidative stress (OS), due to decrease of antioxidant capacity in comparison to normotensive pregnant women. The consequences of increased state of oxidative stress with hypertension disorder in pregnancy are disorder of placental blood flow, intrauterine hypoxia of the fetus and disturbance in transfer of O2 manifested as pathological ultrasound (US) parameters (amount of amniotic fluid and biophysical profile of fetus) and cardiotocography parameters (CTG).

Aim: The aim of this research is to analyze correlation of TBARS oxidative stress markers with ultrasound parameters of pregnancy course and cardiotocography parameters in pregnant women with PIH. Read More
