“…144145 Many recently published scientific manuscripts use the INTERGROWTH-21 st birth weight standard and a cut-off below the 10 th centile to define SGA, but there is no official consensus on its use and the discussion about the correct reference and cut-off to use continues. [146][147][148] Figure 1 summarises the key milestones in the development of the small newborn definitions.…”

“…(2) References/standards: -Serial measurements can be plotted on same growth charts as individual biometric measurements -Various methods to quantify growth velocity (44) (including individualised growth charts (2)), but none are widely implemented in practice Cut-offs: Delphi Consensus Statement for FGR* includes downward crossing of more than two quartiles (43) Foetal body composition Ultrasonography: -Subcutaneous fat thickness -Organ size Gestational age-related Foetal body composition is not routinely assessed, and no universally acknowledged references/standards or cutoffs exist; organ size measurements may be used to assess foetal health conditions (38) *Delphi Consensus Statement for Foetal Growth Restriction (43) International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) (34) . However, 10-15 % errors in estimated foetal weight v. actual weight are not uncommon and may be attributed to high inter-and intra-observer variability in biometric measurements, the choice of equation and the amplification of errors in single parameters when included in a calculation (28,(38)(39)(40)(41)(42) . The aim of foetal growth assessment is the detection of FGR or excessive foetal growth.…”

Objectives: Prenatal growth affects short- and long-term morbidity, mortality and growth, yet communication between prenatal and postnatal healthcare teams is often minimal. This paper aims to develop an integrated, interdisciplinary framework for foetal/ infant growth assessment, contributing to continuity of care across the first 1000 days of life. Design: A multidisciplinary think-tank met regularly over many months to share and debate their practice and research experience related to foetal/ infant growth assessment. Participants’ personal practice and knowledge was verified against and supplemented by published research. Setting: Online and in-person brainstorming sessions of growth assessment practices that are feasible and valuable in resource-limited, low- and middle-income country (LMIC) settings. Participants: A group of obstetricians, paediatricians, dietitians/ nutritionists, and a statistician. Results: Numerous measurements, indices and indicators were identified for growth assessment in the first 1000 days. Relationships between foetal, neonatal and infant measurements were elucidated and integrated in an interdisciplinary framework. Practices relevant to LMICs were then highlighted: antenatal Doppler screening, comprehensive and accurate birth anthropometry (including proportionality of weight, length and head circumference), placenta weighing, and incorporation of length-for-age, weight-for-length and mid-upper arm circumference in routine growth monitoring. The need for appropriate, standardised clinical records and corresponding policies to guide clinical practice and facilitate interdisciplinary communication over time became apparent. Conclusions: Clearer communication between prenatal, perinatal and postnatal health care providers, within the framework of a common understanding of growth assessment and a supportive policy environment, is a prerequisite to continuity of care and optimal health and development outcomes.

“…The reported accuracy of growth US is moderate in detecting a low birth weight [6][7][8]. We aimed to assess the performance of prenatal US scans in detecting smallness in neonates, a function of the severity of growth abnormalities, in our setting.…”

Intrauterine Growth Restriction—Prediction and Peripartum Data on Hospital Care

Background and Objectives: We aimed to prospectively obtain data on pregnancies complicated with intrauterine growth restriction (IUGR) in the Prenatal Diagnosis Unit of the Emergency County Hospital of Craiova. We collected the demographic data of mothers, the prenatal ultrasound (US) features, the intrapartum data, and the immediate postnatal data of newborns. We aimed to assess the detection rates of IUGR fetuses (the performance of the US in estimating the actual neonatal birth weight), to describe the prenatal care pattern in our unit, and to establish predictors for the number of total hospitalization days needed postnatally. Materials and Methods: Data were collected from cases diagnosed with IUGR undergoing prenatal care in our hospital. We compared the percentile of estimated fetal weight (EFW) using the Hadlock 4 technique with the percentile of weight at birth. We retrospectively performed a regression analysis to correlate the variables predicting the number of hospitalization days. Results: Data on 111 women were processed during the period of 1 September 2019–1 September 2022. We confirmed the significant differences in US features between early- (Eo) and late-onset (Lo) IUGR cases. The detection rates were higher if the EFW was lower, and Eo-IUGR was associated with a higher number of US scans. We obtained a mathematical formula for estimating the total number of hospitalization days needed postnatally. Conclusion: Early- and late-onset IUGR have different US features prenatally and different postnatal outcomes. If the US EFW percentile is lower, a prenatal diagnosis is more likely to be made, and a closer follow-up is offered in our hospital. The total number of hospitalization days may be predicted using intrapartum and immediate postnatal data in both groups, having the potential to optimize the final financial costs and to organize the neonatal department efficiently.
