OBJECTIVES: To assess a comprehensive package of ultrasound quality control in a large multicentre study of fetal growth - the Fetal Growth Longitudinal Study of the INTERGROWTH-21(st) Project. METHODS: We performed quality control (QC) measures on 20,313 ultrasound scan images taken prospectively from 4,321 fetuses at 14-41 weeks' gestation in eight geographical locations. At the time of each ultrasound examination, three fetal biometric variables were measured in triplicate on separately generated images: head circumference (HC), abdominal circumference (AC) and femur length (FL)...

OBJECTIVES: Our main objective was to evaluate the feasibility of an automated analysis of fetal myocardial velocity recordings obtained by color tissue Doppler imaging (cTDI). METHODS: This was a prospective cross-sectional observational study of 107 singleton pregnancies in ≥41 weeks of gestation. Myocardial velocity recordings were obtained by cTDI in a long-axis four-chamber view of the fetal heart. Regions of interest (ROI) were placed in the septum, right (RV) and left ventricular (LV) walls at the level of the atrioventricular plane (AV-plane)...

OBJECTIVES: To estimate intra- and inter-rater agreement and reliability with regard to describing ultrasound images of the endometrium using the International Endometrial Tumor Analysis (IETA) terminology. METHODS: Four expert and four non-expert raters assessed video clips of transvaginal ultrasound examinations of the endometrium from 99 women with postmenopausal bleeding and sonographic endometrial thickness ≥4.5 mm and no fluid in the uterine cavity. The following features were rated: endometrial echogenicity (nine categories), endometrial midline (four categories), bright edge (yes, no), endometrial-myometrial junction (four categories), color score (1 to 4), vascular pattern (seven categories), irregularly branching vessels (yes, no), color splashes (yes, no)...

OBJECTIVE: Ultrasonographic assessment of the cerebroplacental ratio (CPR) and middle cerebral artery (MCA) Doppler is widely used as an additional method to umbilical artery (UA) Doppler to identify fetuses at risk of adverse perinatal outcomes. However, reported estimates of its accuracy vary considerably. We conducted a systematic review with meta-analysis of studies on the prognostic accuracy of CPR and MCA Doppler, and compared this to UA Doppler. METHODS: We queried PubMed, EMBASE, the Cochrane Library, and ClinicalTrials...

OBJECTIVES: Red cell alloimmunisation affects up to 0.6% of all live births, and can be successfully treated with intrauterine fetal blood transfusion. Fetal middle cerebral artery (MCA) Doppler peak systolic velocity (PSV) is a non-invasive test, to identify fetal anaemia and requiring intrauterine transfusion (IUT). Traditionally, timing of subsequent IUTs has involved estimating a fall in fetal haematocrit of 1% per day, or a fall in fetal haemoglobin of 0.3 g/dL per day. The aim of this pragmatic multi-centre randomised trial was to evaluate whether Doppler MCA-PSV in the fetus that has undergone one IUT for anaemia secondary to red cell alloimmunisation was non-inferior to timing IUT by timing based on predicting the fall in fetal haematocrit or fetal haemoglobin, without compromising infant haemoglobin at birth...

Incidence of abnormal invasion of the placenta (AIP) is increasing as rates of caesarean section increase. Recently, a conservative surgical technique called the "the Triple P procedure" (perioperative placental localization, delivery with transverse uterine incision above the placenta, pelvic devascularisation and placental non-separation) has been proposed as an alternative to elective peripartum hysterectomy to reduce the risk of hysterectomy, reduce blood loss and hospital stay when compared to hysterectomy (1)...

OBJECTIVE: Hypertensive disorders of pregnancy (HDP) are associated with impaired placentation, as evidenced by abnormal uterine artery (UtA) Doppler. UtA mean pulsatility index (PI) shows a progressive decline with gestational age (GA). However, previous studies have reported that a proportion of pregnancies demonstrate worsening of the UtA Doppler. The aim of this study was to investigate the incidence of HDP according to the change in the UtA mean PI between the second and third trimester...

Professional guidelines define the second stage of labor as 'prolonged' at three hours for primiparous women with an epidural and two hours without, and at two hours for parous women with an epidural and one hour without(1). NICE guidelines from the UK define second stage length similarly, but take into consideration passive time at full cervical dilation and the time in active pushing(2).

OBJECTIVE: To estimate the risk for fetal trisomy 21 (T21) and other chromosomal abnormalities at 11-13 week's gestation using computational intelligence classification methods. METHODS: As a first step, we train the artificial neural networks with 72054 euploid pregnancies, 295 cases of T21 and 305 of other chromosomal abnormalities (OCA). Then, we sort the cases into two categories of "no-risk" and "risk". The cases of "no-risk" are no further examined, while the cases with "risk" are forwarded in Stage 2 for further examination where we classify them in three types of risk, namely "no-risk", "moderate-risk" and "high-risk"...

The United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) recently reported a reduction in the average overall mortality among ovarian cancer patients screened with an annual sequential, multimodal strategy that tracked biomarker CA125 over time, where increasing serum CA125 levels prompted ultrasound. However, multiple cases were documented wherein serum CA125 levels were rising, but ultrasound screens were normal, thus delaying surgical intervention. A significant factor which could contribute to false negatives is that many aggressive ovarian cancers are believed to arise from epithelial cells on the fimbriae of the fallopian tubes, which are not readily imaged...
