“…Compared with controls, VI was higher in pregnancies complicated by CH and FI was significantly lower in all hypertensive groups [34]. The authors suggested that the increase in VI noted in women with CH may represent a placental response ─ elevated vascularization rate ─ to increased maternal blood pressure and hypothesised that the reduction in FI seen throughout the groups reflected impaired perfusion in the placenta [34]. Within obese cohorts, it has been suggested that flow indices are relatively unreliable for prediction of PE [9], and that future research should focus only on the role of vascularization indices (VI and VFI) [9,36].…”

“…In the first trimester, hyperglycaemia triggers vasculogenesis but vasculopathy occurs later [31]; therefore reduction in placental blood flow (FI) and alterations in vascularization indices typically noted in later pregnancy are not yet apparent [31,33]. Variation in the performance of PVIs has also been demonstrated in pregnancies complicated by chronic hypertension (CH), gestational hypertension and PE (n=226) [34,35]. Compared with controls, VI was higher in pregnancies complicated by CH and FI was significantly lower in all hypertensive groups [34].…”

Objective: To assess ability of first and second trimester Placental Vascularization Indices (PVIs); Vascularization Index (VI), Flow Index (FI) and Vascularization Flow Index (VFI) to predict pre-eclampsia (PE) in high-risk pregnancies. Method: PVIs derived from 3-Dimensional power Doppler imaging were measured at 11+0-13+6 (n=194) and 19+0-21+6 weeks (n=195). Logistic regression (LR) models used PE as the outcome. To quantify added value of PVIs to baseline characteristics in predicting PE, integrated discrimination improvement (IDI) and net reclassification improvement (NRI) indices were calculated. Results: Overall rate of PE was 12% (n=26). Lower first trimester PVIs were seen in women with PE (mean, SD);

“…When adjusted for other confounding variable in the regression analysis, placental weight was a significant predictor of birth weight, crown-heel length and head circumference. Other studies have also shown that placental weight was a predictor of birth weight (11)(12)(13)(14)(15), neonatal length and head circumference (11). Several studies have suggested that the placental weight/birth weight ratio is a useful marker for pregnancy outcome (30,31).…”

“…The birth weight of a baby depends not only on the mother's nutrition but also on the placenta's ability to transport nutrients to it from its mother (2). Placental weight and volume can predict pregnancy outcome and thus the future health of the newborn (12)(13)(14). For example, placental size and shape has been reported to predict blood pressure at age 9 years (15).…”

Différences en matière d'issues de grossesse et leurs prédicteurs entre les diverses nationalités résidant au KoweïtRÉSUMÉ La présente étude visait à analyser les différences en matière d'issue de grossesse entre les différentes nationalités résidant au Koweït. Des données transversales ont été recueillies auprès de 369 dyades mère-nouveauné au moment de l'accouchement sur la taille de la mère, l'hémoglobine (Hb) maternelle, l'hémoglobine de l'enfant (Hbe), le périmètre brachial (PB), l'âge gestationnel, le poids du placenta (PP), le poids de naissance (PN), la taille vertex-talon (TVT), et le périmètre crânien (PC). Des différences significatives ont été observées entre les diverses nationalités en ce qui concerne l'Hb maternelle, le PC, le LVT, le PP et la taille de la mère. Les femmes koweïtiennes et indiennes présentaient un PP plus faible et leurs bébés avaient un PC et une TVT inférieures. La prévalence de l'anémie (Hb <11,0 g/dL) était comprise entre 7,1 % (Libanaises) et 30,0 % (Koweïtiennes) avec une prévalence globale de 19,5 %. La prévalence du faible poids de naissance était de 3,5 %. L'analyse de régression linéaire multiple a révélé que le PP constituait un facteur prédictif pour le PN, la LVT et le PC. Des différences significatives ont été observées entre les diverses nationalités en termes d'Hb maternelle, de PC, de LVT, de PP et de taille de la mère. L'importance de ces différences et les facteurs qui y contribuent nécessitent des recherches supplémentaires. ABSTRACT This study aimed to investigate differences in pregnancy outcome among various nationalities residing in Kuwait. Cross-sectional data were collected from 369 mother-infant dyads at delivery on mother height (MH), mother haemoglobin (mHb), child haemoglobin (cHb), mid-upper arm circumference (MUAC), gestational age (GA), placental weight (PW), birth weight (BW), crown-heal length (CHL), and head circumference (HC). Significant differences among various nationalities were observed in mHb, HC, CHL, PW and MH. Kuwaiti and Indian women had lower PW and their babies had lower HC and CHL. Prevalence of anaemia (Hb <11.0 g/dL) ranged from 7.1% (Lebanese) to 30.0% (Kuwaiti) with the overall prevalence of 19.5%. Prevalence of low birth weight was 3.5%. Multiple linear regression analysis revealed PW as a significant predictor of BW, CHL and HC. Significant differences among various nationalities were observed in mHb, HC, CHL, PW and MH.The significance of these differences and their contributing factors needs further research. ‫الكويت‬ ‫يف‬ ‫املقيمة‬ ‫املختلفة‬ ‫اجلنسيات‬ ‫بني‬ ‫ومنبئاته‬ ‫احلمل‬ ‫نتائج‬ ‫يف‬ ‫االختالفات‬

Objectives We aimed to investigate and compare placental vascularization indices between monochorionic-diamniotic, dichorionic-diamniotic normal twin pregnancies, and normal singular pregnancies. We hypothesized that there is correlation between placental three-dimensional power Doppler vascularization indices and birth weight in case of twin pregnancies, and that normal singular pregnancies have higher placental vascularization indices than normal twin pregnancies. Results Vascularization indices and birth weight were significantly (p<0.01) higher in normal singular gestations (vascularization index=10.36, flow index=46.08, vascularization-flow index=4.08, average birth weight=3377g at 38.2 weeks average gestational age) compared to monochorionic-diamniotic and dichorionic-diamniotic normal twin pregnancies. No significant differences were found in vascularization indices between monochorionic-diamniotic and dichorionic-diamniotic normal twins. There were no significant differences in APGAR score, umbilical pH, umbilical venous bicarbonate, lactate, and base excess between groups examined (p<0.01). We found strong linear correlations between placental vascularization indices and birth Study design ABBREVIATIONS:There are no abbreviations.
