84: Performance of third trimester biometry for gestational age assessment in low resource settings: Results of the multi-country, population-based WHO AMANHI late pregnancy dating sStudy
To evaluate the accuracy of late pregnancy ultrasound biometry for establishment of gestational age (GA) in low-middle income country (LMIC) settings, where women may present late for care with poor dating, and where a high burden of fetal growth restriction exists.

Obstetric Ultrasound Guidelines and Recommendations: What’s New for 2015? NICHD Guidelines
The National Institute of Child Health and Human Development held a multidisciplinary conference in 2012 to discuss indications for obstetrical ultrasound and for MRI during pregnancy to make recommendations that would optimize the yield of prenatal imaging while minimizing cost. The conference summary was published in 2014 and will be presented during this lecture. The summary discusses first trimester dating and screening from 11-13.9 weeks. During the second trimester, the use of ultrasound for dating is discussed, as well as screening for congenital anomalies, and monitoring cervical length.

Abstract B98: Do demographic characteristics and theoretical mediators of health behavior differentiate American Indian adherent mammographic screeners from non-adherent screeners?
Conclusions: No single theoretical model appears to differentiate adherent from non-adherent screeners, but mediators associated with each of the various models do differentiate these screeners. These differentiating mediators should be considered for how they might guide development of interventions to improve screening behavior. The self-report nature of the survey demands that results be considered as tentative and limited, in any case, to the respondents of this tribe.Citation Format: Wesley O. Petersen, Ann M.

Advances in abortion care technology and management
Purpose of review To review emerging evidence specific to abortion care, including diagnostic testing and pain management. Recent findings Recent advances in abortion care include improvements in gestational age dating, Rh status testing, and pain management methods. When ultrasound technology is available, the use of crown-rump length (CRL)-based dating is more accurate up to 13 weeks and composite CRL and biometry between 13 and 14 weeks. Evidence supports using updated fetal foot length-to-gestational age reference ranges for postprocedure gestational age confirmation. Serum tests for two placental proteins, ...

Maternal and fetal factors which affect fetometry: use of in vitro fertilization and birth register data
Conclusions: In most IVF pregnancies, routine fetometry correctly predicts gestational age but deviations exist which indicate that ultrasound underestimates the age of fetuses that will be born small for gestational age and when the woman is obese. The differences between actual age and estimates based on fetometry seem to be smaller than those between estimates based on last menstrual period and fetometry.

Fetal Biometry in Assessing Size and Growth
This article discusses the evidence based recommended methods of pregnancy dating and biometric measurements. We address some confusing terms such as fetal growth ‘standards’ and fetal growth ‘references’ along with explaining the differences between prescriptive and descriptive charts and between growth charts, based on estimated fetal weight vs those based on birth weight. Opinions remain divided on which charts are best to use, however, since the publication of the Intergrowth 21st study, we are now in a position to be able to assess growth and development in an internationally standardized fashion, from fetal l...

Fetal biometry to assess the size and growth of the fetus
This article discusses evidence-based recommended methods for pregnancy dating and biometric measurements. We address some confusing terms such as fetal growth “standards” and fetal growth “references” along with explaining the differences between prescriptive and descriptive charts and between growth charts based on estimated fetal weight vs those based on birth weight. Opinions remain divided on which charts are best to use; however, since the publication of the Intergrowth 21st study, we are now in a position to be able to assess growth and development in an internationally standardized fashion, from fetal life ...

Fetal Medicine Foundation fetal and neonatal population weight charts.
CONCLUSION: We established a BW chart for the population of all babies at a given gestational age, including those still in utero, which overcomes the problem of underestimation of growth restriction in preterm births. The BW and EFW charts have a common median but they differ in the levels of spread from the median. PMID: 29696704 [PubMed - as supplied by publisher]

Perinatal outcomes associated with maternal HIV and antiretroviral therapy in pregnancies with accurate gestational age in South Africa
Conclusion: Despite high ART coverage, good maternal health and very low vertical HIV transmission rate, maternal HIV infection remained associated with increased risk of adverse perinatal outcomes. Larger studies using first trimester ultrasound for pregnancy dating are needed to further assess associations with specific adverse perinatal outcomes.

Acute renal failure and bladder tumors, about 106 cases
CONCLUSION: Acute renal failure is a frequent and severe complication of bladder tumors that can be life-threatening and makes it difficult to treat bladder tumors requiring multidisciplinary management.PMID:35181289 | DOI:10.1016/j.nephro.2021.10.005
