“…In this study, a significant positive correlation was found between the magnesium level in AF and umbilical artery pulsatility index (UAPI). The association between these parameters was also demonstrated in other studies [ 31 – 33 ]. Moreover, it was observed that the UAPI value, like the magnesium concentration, decreases with gestational age [ 18 , 31 ].…”

The concentrations of various trace elements in amniotic fluid (AF) change over the course of pregnancy, with gestational age and fetus growth. The aim of the present study was to evaluate the concentrations of selected essential and toxic elements in AF and their relations to maternal and fetal parameters. The study was carried out in 39 pregnant women, aged 34.6 ± 4.7 years, between weeks 16 and 26 of gestation. Amniotic fluid samples were obtained during the standard procedure of amniocentesis in high-risk patients for chromosomal abnormalities. An inductively coupled plasma mass spectrometry (ICP-MS) technique was used to determine the levels of Al, As, Ba, Cd, Co, Cr, Cu, Mg, Mn, Ni, Sr, U, and V in AF. Body mass and blood pressure were measured in all the women. The basic parameters of fetal development were also assayed. It was found that the age of the mother, the gender of the fetus, and the week of the pregnancy may affect the concentrations of mineral in the amniotic fluid. Moreover, several significant correlations between the essential and toxic elements and maternal and fetal parameters were observed. In particular, negative and positive correlations between fetal parameters and magnesium and copper levels in AF, respectively, were seen. The present findings demonstrate the association between minerals in AF and fetal development.

“…Fetal hemodynamic study is routine in clinical practice since 1977, with the velocymetric analysis of UmA and the MCA and the capacity to diagnose fetal perfusion abnormities (6,20). Therefore, evaluation of the perfusion of intra uterine organs and it correlation with the well -being of the fetus become possible 12 This study had shown that these curves have a parabolic pattern and that they have the same shape of others curves found elsewhere in the world (3,6,14,(21)(22)(23)(24)(25)(26).…”

Background: Mother and fetal Doppler ultrasound during pregnancy is an established and safe tool for quantitative analysis of the utero-placental and the fetoplacental blood flow and seems to be affected by Ethnic hetérogenicity. Objective. To establish normative data for the resistive index of Uterine arteries, Umbilical artery and middle cerebral artery of Cameroonian pregnant women in the second half of pregnancy using multiples of the median and percentile reference range.Methods. We conducted a cross-sectional study on 93 low risk singleton gestation women aged above 18 years between 28 and 39 weeks of gestation in two hospitals in Cameroon during 7 months. We seek for resistive index (RI) of both left and right uterine arteries (LUt and RUt), Umbilical artery (UmA) and Middle cerebral artery (MCA). We also estimated the gestational age (GA), the mother age, the fetal weight (EFW) and the cerebro – placental ration (CPR).Pearson's correlation analysis of the relationship between these RI and selected maternal parameters was done. Regression modeling across gestational age was performed to obtain the reference values and normogram curve with values ranged at 5 and 95th percentiles. P < 0.05 was considered statistically significant.Results. The mean GA and EFW was 33.5 +/- 2.92 weeks (médian of 34) and 2337.5 +/- 734 g respectively. The means RI value of target vessels were 0.55 +/- 0.077; 0.76 +/- 0.071 ; 0.48 +/- 0.077 and 0.46 +/-0.087 for UmA, McA, RUt and LUt with extremes values of des 0.38 to 0.77 ; 0.49 to 0.87; 0.30 to 0.70 and 0.29 to 0.69 respectively. Only UmA RI and CPR values had shown correlations with GA (r= - 0.338, p≤0.01 and r=0.314; p≤0.001) and EFW (r=-0.445, p≤0.001 and r=0.234; p = 0.02). No difference between LUt and RUt RI values was found. The nomogram curve for UmA, McA, RUt and LUt value revealed a general low RI values of in our sample.Conclusions. Fetal Doppler should carefully interpreted according to general low RI values during low risk singleton pregnancy shown by this study. The generated 5and 95th percentiles RI values curves for each target vessel could be useful in that way.Trial registration:N°431/UY1/FMSB/VDRC/CSD du 24 mai 2017 by the Institutional Review Board at the faculty of Medicine and Biomedical Sciences of University of Yaoundé 1.
