Assessment of Placental Weight, Newborn Birth Weight in Normal Pregnant Women and Anemic Pregnant Women: A Co-relation and Comparative Study

ABSTRACT The serum concentration of human chorionic somatomammotropin (HCS) during the third trimester of pregnancy has been measured in 56 insulintreated diabetic women. A total of 318 serum samples were estimated and compared with a control material of 134 serum samples from normal pregnant women. The HCS concentration was found to be significantly higher in diabetic than in normal pregnancies. Significantly positive correlations were demonstrated between the HCS concentration and the placental weight, the birth weight of the infant and the oestriol excretion, respectively. Evidence is presented that simultaneous determinations of HCS and urinary oestriol would be valuable in the management of diabetic pregnancies.

In Pregnancy

ABSTRACT Studies of iodine metabolism have been carried out in 15 pregnant women, 33 cases with sporadic goitre and 11 with thyrotoxicosis. A low plasma inorganic iodine was common to the three groups. In pregnancy and sporadic goitre the thyroid clearance of iodine was elevated and the absolute iodine uptake normal. A high thyroid clearance of iodine in thyrotoxicosis was associated with a high absolute iodine uptake. The results suggest that both pregnancy and sporadic goitre are physiological responses to an iodine deficiency state while the iodine deficiency state of thyrotoxicosis is secondary to increased thyroid activity.

Prospective Case Control Study

Background: Placenta plays a very important role in the growth and development of fetus. Objective: To know the correlation between placental weight and perinatal outcome in term antenatal women. Methods: Present prospective case-control study was conducted in the rural tertiary center of Northern India over one year (January-December 2018) on 1,118 term (≥37-≤42 weeks) antenatal women with singleton pregnancy fulfilling inclusion criteria with 559 women with high-risk pregnancy as cases and 559 low-risk pregnant women as controls. Placental weight, birth weight was measured immediately after delivery and compared between the two groups along with gestation, parity, fetal gender, and neonatal outcome. Statistical analysis was done using SPSS 22 version. Results: Mean placental weight [481.98±67.83 gm vs. 499.47±59.59 gm (p=.000)] and birth weight [2.68±0.53 Kg vs. 2.88±0.4 Kg (p=.000)] was significantly lower in high risk as compared to lowrisk participants, whereas placental birth weight ratio was higher in high-risk cases [18.35±2.37 vs. 17.41±1.38 (p=.000)] respectively. Placental weight was positively correlated with birth weight and placental weight and birth weight increased with increasing gestation in both cases and controls. Male neonates had higher placental weight [492.74±68.24 gm vs. 488±58.8 gm (p=0.224)] and birth weight [2.81±0.5 Kg vs. 2.74±0.45 Kg (p=0.033)] as compared to females. Neonatal Intensive Care Unit admission was significantly associated with low placental and birth weight (p=.000). Conclusion: There is a significant correlation between placental weight, birth weight and neonatal outcome, hence placental weight can be used as an indirect indicator of intrauterine fetal growth.

Maternal And Neonatal Outcomes

Background: Advanced maternal age is an important predictor for maternal and neonatal outcomes such as maternal mortality, low birth weight, stillbirth, preterm birth, cesarean section and preeclampsia. Objective: To determine the association of advanced maternal age and adverse maternal and neonatal outcomes in Iranian pregnant women. Methods: In this hospital-based cross-sectional study, 5117 pregnant women from 103 hospitals in Tehran, Iran, were participated in the study in 2015. The required data were gathered from hospitals which equipped to the department of obstetrics and gynecology. Advanced maternal age was considered as an independent variable and unwanted pregnancy, preeclampsia, preterm birth, cesarean section and low birth weight were considered as interested outcomes. Results: In our study, the prevalence of advanced maternal age was 12.08%. Advanced maternal age was significantly associated with higher risk of unwanted pregnancy (OR: 1.39, 95% CI: 1.12-1.73), preterm birth (OR: 1.75, 95% CI: 1.28- 2.39) and cesarean section (OR: 1.34, 95% CI: 1.03-1.74). In our study, there was no significant relationship between advanced maternal age and preeclampsia but this relationship could be clinically important (OR: 1.48, 95% CI: 0.99-2.20, P=0.052), and there is no significant relationship between advanced maternal age and low birth weight (OR: 1.08, 95% CI: 0.67-1.74, P=0.736). Conclusion: Advanced maternal age is associated with higher risk of unintended pregnancy, preterm birth and cesarean section but our findings did not support advanced maternal age as a risk factor associated with low birth weight.

Background: Pregnancy may increase the risk of Human Papillomavirus (HPV) infection because of pregnancy induced immune suppression. The objective of this study was to use a large population-based dataset to estimate the prevalence of HPV infection and its association with adverse outcomes among pregnant women. Methods: We analyzed Pregnancy Risk Monitoring System data from 2004-2011 (N=26,085) to estimate the self-reported HPV infection. Survey logistic procedures were used to examine the relationship between HPV infection and adverse perinatal outcomes. Results: Approximately 1.4% of women were estimated to have HPV infection during their pregnancy. The prevalence of adverse outcomes in this sample was preterm birth (8.4%), preeclampsia (7.5%), low birth weight (6.3%) and premature rupture of membranes (2.8%). Compared to women without HPV infection, HPV infection positive women were much more likely to have had other infections such as chlamydia (9.23% vs. 2.12%, p-value <.0001), Group B Strep (21.7% vs. 10.04%, p-value <.0001), and herpes (7.17% vs. 1.07%, p-value <.0001). After adjusting for other risk factors including other infections, HPV infection was significantly associated with low birth weight (OR: 1.94, 95% CI: 1.14-3.30). Conclusion: The study indicated a potential association between HPV infection and low birth weight. Because pregnant women with HPV infection are at higher risk of other infections, future research may focus on the roles of co-infection in the development of adverse perinatal effects.

AbstractThe relationship among social determinants, vitamin D serum concentration and the health and nutrition conditions is an important issue in the healthcare of pregnant women and newborns. Thus, the present study analyses how vitamin D, prenatal monitoring and social determinants are associated with birth weight. The cohort comprised 329 pregnant women, up to 34 weeks gestational age at the time of admission, who were receiving care through the prenatal services of Family Health Units. Structural equation modelling was used in the statistical analysis. The mean birth weight was 3340 (sd 0·545) g. Each nmol increase in maternal vitamin D serum concentration was associated with an increase in birth weight of 3·06 g. Prenatal healthcare with fewer appointments (β −41·49 g, 95 % CI −79·27, −3·71) and late onset of care in the second trimester or third trimester (β −39·24 g, 95 % CI −73·31, −5·16) favoured decreased birth weight. In addition, low socio-economic class and the practice of Afro-Brazilian religions showed a direct association with high vitamin D serum concentrations and an indirect association with high birth weight, respectively. High gestational BMI (β 23·84, 95 % CI 4·37, 43·31), maternal education level (β 24·52 g, 95 % CI 1·82, 47·23) and length of gestation (β 79·71, 95 % CI 52·81; 106·6) resulted in high birth weight. In conclusion, maternal vitamin D serum concentration, social determinants and prenatal care, evaluated in the context of primary healthcare, directly determined birth weight.
