Sex differences in fetal growth and immediate birth outcomes in a low-risk Caucasian population

AbstractBackgroundAccording to the WHO Multicentre Growth Reference Study Group recommendations, boys and girls have different growth trajectories after birth. Our aim was to develop gender-specific fetal growth curves in a low-risk population and to compare immediate birth outcomes.MethodsFirst, second, and third trimester fetal ultrasound examinations were conducted between 2002 and 2012. The data was selected using the following criteria: routine examinations in uncomplicated singleton pregnancies, Caucasian ethnicity, and confirmation of gestational age by a crown-rump length (CRL) measurement in the first trimester. Generalized Additive Model for Location, Scale and Shape (GAMLSS) was used to align the time frames of the longitudinal fetal measurements, corresponding with the methods of the postnatal growth curves of the WHO MGRS Group.ResultsA total of 27,680 complete scans were selected from the astraia © ultrasound database representing 12,368 pregnancies. Gender-specific fetal growth curves for biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) were derived. The HC and BPD were significantly larger in boys compared to girls from 20 weeks of gestation onwards (p

Intertwin discordance in fetal size at 11-13 weeks' gestation and pregnancy outcome. Ultrasound Obstet Gynecol. 2019 Nov 11;: Authors: Litwinska E, Syngelaki A, Cimpoca B, Sapantzoglou I, Nicolaides KH Abstract OBJECTIVES: To investigate the value of inter-twin discordance in fetal crown-rump length (CRL) at the 11-13 weeks scan in the prediction of adverse outcome in dichorionic (DC), monochorionic diamniotic (MCDA) and monochorionic monoamniotic (MCMA) twin pregnancies. METHODS: This was a retrospective analysis of prospectively collected data on twin pregnancies undergoing routin...

Infertility is defined by failure to achieve a pregnancy after 12 months or more of appropriate timed unprotected intercourse or therapeutic donor insemination. Ultrasound has now become an essential component of the modern investigation of female infertility and the management of assisted conception. Scans are predominantly performed transvaginally and recent technological advances such as 3D and Doppler imaging enhance our understanding of ovarian function such as ovarian reserve, follicular maturity and the assessment of polycystic morphology in the identification of polycystic ovarian syndrome. This chapter describes t...

CONCLUSIONS: The problem of unexpected non-cephalic presentation in labor can to a great extent be overcome by a routine ultrasound examination at 35+0 - 36+6 weeks' gestation. The incidence of non-cephalic presentation at the 35+0 - 36+6 weeks scan was about 5%, but, in about 40% of these cases the presentation at birth was cephalic, mainly due to subsequent spontaneous rotation and to a lesser extent as a consequence of successful ECV.

AbstractBackgroundEndometriosis can exert obvious negative effects on women ’s quality of life.Excisional surgery is among the most effective treatments for severe pelvic endometriosis. The prevalence of severe pelvic adhesions following a laparoscopic examination of severe endometriosis varies between 50 and 100%. Temporary intraoperative ovarian suspension is a method for the reduction of adhesions is in the treatment of severe pelvic endometriosis. Given the importance and the prevalence of endometriosis and its complications, we conducted the present study to determine more effective adhesion-reducing methods wit...

ConclusionWomen with IVF-related EUP were less symptomatic upon presentation and underwent surgery for first-line treatment more often than those with spontaneous EUP did. The type of conception was not a prognostic factor for success of first-line conservative treatment. Observation alone was more successful among IVF pregnancies.
