Preeclampsia (PE) is a common and proprietary complication during pregnancy. The correlation was found between the levels of HtrA3 and TGF-β 2 and preeclampsia (PE). This study aimed to detect the HtrA3 and TGF-β2 in different parts of the third trimester (maternal serum, placenta). The 102 pregnant women who were eligible for enrollment in the obstetric examination at Tengzhou Maternity and Child Health Hospital from June 2020 to December 2020 were selected as the research objects. 28 cases diagnosed with PE were set up as the observation group 1, and 24 cases diagnosed with severe PE were set up as the observation group 2. Select 50 normal pregnant women as the control group and research the expressions of HtrA3 and TGF-β2 in maternal blood and placental tissues of patients with PE. ELISA was used to measure the concentration of HtrA3 and TGF-β2 in maternal blood. The distribution of HtrA3 and TGF-β2 in the placenta was observed by immunohistochemical techniques (IHC) and mean optical density value (MOD). S/D was measured by using color Doppler ultrasonic. The concentration of HtrA3 and TGF-β2 in the maternal blood and placenta tissue was higher in severe PE compared with PE and normotensive pregnancy, respectively ( P < 0.05 ). There is a negative correlation between the level of HtrA3 and TGF-β2 and the birthweight of newborns both in maternal plasma and placenta tissue in preeclampsia and positive correlation between HtrA3 and TGF-β2 levels and S/D. HtrA3 and TGF-β2 may correlate with severity of PE and their neonatal adverse outcomes.

Activin A levels are elevated in maternal serum of pregnant women with hypertensive disturbances. Because follistatin is a circulating binding protein for activin A, the present study was designed to evaluate whether serum follistatin and activin A levels also change in patients with hypertensive disorders in the last gestational trimester. The study design was a controlled survey performed in the setting of an academic prenatal care unit. Healthy pregnant women (controls, n=38) were compared with patients suffering from pregnancy-induced hypertension (PIH, n=18) or pre-eclampsia (n=16). In addition, the study included a subset of patients with pre-eclampsia associated with intrauterine growth restriction (IUGR, n=5). Maternal blood samples were withdrawn at the time of diagnosis (patients) or in a random prenatal visit (controls), and serum was assayed for follistatin and activin A levels using specific enzyme immunoassays. Hormone concentrations were corrected for gestational age by conversion to multiples of median (MoM) of the healthy controls of the same gestational age. Follistatin levels were not different between controls and patients, while activin A levels were significantly increased in patients with PIH (1.8 MoM), pre-eclampsia (4.6 MoM), and pre-eclampsia+IUGR (3.2 MoM, P<0.01, ANOVA). The ratio between activin A and follistatin was significantly increased in patients with PIH (1.5 MoM) and was further increased in patients with pre-eclampsia (4.5 MoM) and in the group with pre-eclampsia+IUGR (2.6 MoM). Follistatin levels were positively correlated with gestational age in control subjects (r=0. 36, P<0.05) and in patients with PIH (r=0.46, P<0.05) or pre-eclampsia (r=0.61, P<0.01), while activin A correlated with gestational age only in the healthy control group (r=0.69, P<0.0001). The finding of apparently normal follistatin and high activin A levels in patients with PIH and pre-eclampsia suggests that unbound, biologically active, activin A is increased in women with these gestational diseases.

Objectives To analyse intake of vitamin A (VA) and retinol concentrations in maternal blood, breast milk (BM), and the umbilical cord (UC) of newborns, and to determine the associations among these variables. Methods We performed a cross-sectional, epidemiological study of 180 mother–newborn dyads. Maternal and UC blood samples and BM were collected. VA intake by the mother over 30 days was assessed using a questionnaire. Results Mean retinol concentrations in maternal serum, the UC, and BM were 0.65 ± 0.27, 0.36 ± 0.18, and 2.95 ± 2.70 µmol/L, respectively. Retinol concentrations <0.70 µmol/L were found in 57.2% of maternal blood samples and in 94.9% of UC samples. A total of 27.9% of BM samples showed retinol concentrations <1.05 µmol/L. Mean VA intake by the mothers was 1041.33 ± 1187.86 µg retinol activity equivalents/day and was inadequate (<550 µg retinol activity equivalents/day) in 44.7%. Conclusions High proportions of insufficient retinol concentrations were observed in the UC, maternal blood, and BM. A high percentage of pregnant women had inadequate VA intake. Mothers with insufficient serum retinol concentrations had newborns with lower retinol concentrations in the UC. Higher retinol concentrations were observed in maternal blood and the UC with a higher VA intake.

Abstract Objective We aimed to investigate the prognostic value of maternal serum haptoglobin levels in patients presenting with preterm premature rupture of fetal membranes (PPROM) during the second and the third trimesters of pregnancy. Methods In this case control study, 60 patients were recruited (30 pregnant women with PPROM between 26–34 weeks of gestation and 30 healthy, gestational-age-matched pregnant women without PPROM). White blood cell count (WBC), interleukin 6 (IL-6), C-reactive protein (CRP), sedimentation rate, and haptoglobin levels were measured. Results The mean age, gestational week, gravida, and parity of the 2 groups were statistically comparable (P>0.001). There was a statistically significant difference between the 2 groups in terms of haptoglobin values (p<0.001). The mean haptoglobin level was 115.5+33.1(mg/dl) in the PPROM group and 66.5+42.6 (mg/dl) in the control group. ROC curve analysis was performed to determine whether the level of haptoglobin alone could diagnose PPROM as an independent marker. It was shown that the level of 94.5 mg/dL for haptoglobin could indicate the diagnosis of PPROM with 80% sensitivity and specificity Conclusion Maternal serum haptoglobin levels may be a diagnostic marker for suspected PPROM cases when membrane rupture diagnosis is not accurate based on physical examination and other diagnostic tests.

The scope of this article was to investigate whether intercessory prayer (IP) influences the adverse outcomes of pregnancies. A double-blind, randomized clinical trial was conducted with 564 pregnant women attending a prenatal public health care service. The women were randomly assigned to an IP group or to a control group (n = 289 per group). They were simultaneously and randomly assigned to practice prayer off-site or not. The following parameters were evaluated: Apgar scores, type of delivery and birth weight. The mean age of the women was 25.1 years of age (± 7.4), and the average gestational age was 23.4 weeks (± 8.1). The average number of years of schooling for the women was 8.1 years (± 3.1). The women in the IP and control groups presented a similar number of adverse medical events with non-significant p. No significant differences were detected in the frequency of adverse outcomes in pregnant women who practiced IP and those in the control group.

ABSTRACT In 14 healthy pregnant women at term progesterone (P) and 20α-dihydroprogesterone (20α-DHP) were determined by radioimmunoassay both in the maternal and foetal compartments. The average concentrations were as follows (ng/ml blood or ng/g wet weight tissue): peripheral maternal blood P 56 ± 26, 20α-DHP 16 ± 8; placental tissue P 2514 ± 1516, 20α-DHP 429 ± 412; placental blood P 365 ± 160, 20α-DHP 35 ± 18; blood of the umbilical vein P 388 ± 121, 20α-DHP 33 ± 15; blood of the umbilical arteries P 162 ± 62, 20α-DHP 28 ± 10. In 5 healthy pregnant women at term progesterone (P), 20α-dihydroprogesterone (20α-DHP) and 20β-dihydroprogesterone (20β-DHP) were also determined by gas-liquid chromatography both in the maternal and foetal compartments. The average concentrations were as follows (ng/ml plasma or ng/g wet weight tissue): peripheral maternal plasma P 129 ± 49, 20α-DHP 15 ± 15, 20β-DHP 1.7 ± 0.9; placental tissue P 5060 ± 1435, 20α-DHP 230 ± 158, 20β-DHP 38 ± 30; placental plasma P 723 ± 245, 20α-DHP 24 ± 13, 20β-DHP 1.0 ± 0.1; plasma of the umbilical vein P 704 ± 227, 20α-DHP 17 ± 3, 20β-DHP 1.2 ± 0.3; plasma of the umbilical arteries P 324 ± 94, 20α-DHP 17 ± 5, 20β-DHP 2.6 ± 2.1 These results show that, contrary to the progesterone concentrations, no significant difference exists in the concentrations of 20α-DHP and 20β-DHP between the blood from the umbilical vein and arteries. Furthermore, no significant difference could be found in the concentrations of P and 20α-DHP between the sexes in either the blood from the umbilical vein or from the umbilical arteries.

Abstract Background: Perinatal mood disorders can seriously endanger the health of pregnant women and fetus, affect family relationships and cause heavy burden and potential hazards to family and society. This study aims to investigate anxiety and depression in second trimester pregnant women with cervical insufficiency (CI) and identify its risk factors, so as to provide guidance for daily clinic work.Methods: From April 2019 to July 2020, 98 mid-pregnancy women with CI underwent laparoscopic cervical cerclage in the First Affiliated Hospital of Sun Yat-sen University were selected as observation group and 166 normal pregnant women in second trimester were set as control group. Zung's Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were applied to evaluate perinatal mood disorders in both groups.Results: Pregnant women in CI group had a SAS score of 46.31±11.29 and SDS score of 54.12±11.72, higher than the SAS score of 41.63±7.70 and SDS score of 47.56±9.31 in control group (both P<0.001). While 32.65% and 67.35% of pregnant women in observation group were considered to have different degrees of anxiety and depression, only 15.06% and 30.72% of normal pregnant women meet the same condition (both P<0.001). Multiple logistic regression analysis indicated that educational experience is an independent protective factor for depression disorder in second trimester pregnant women with CI.Conclusion: Pregnant women with CI are prone to develop anxiety and depression in the second trimester than normal pregnant women, therefore doctors and nurses should pay more attention to them in clinic work.

Background: Preterm delivery is one of the main causes of infant death. Therefore, prediction of preterm delivery may eliminate a large number of prenatal complications. Objectives: The present study aimed to understand if preterm delivery can be predicted by assessing maternal plasma fibronectin concentration. Materials and Methods: Serum samples from 105 pregnant women participating in this study were collected. The plasma fibronectin were measured at 24-28 wk of gestation and again at 32-36 wk of gestation. Unfortunately, only 65 of the 105 pregnant women, returned for the second sampling. The plasma fibronectin was analyzed using ELISA method and its concentration in term and preterm deliveries was compared. The delivery dates of all the women were also recorded. Results: Out of 105 pregnant women, 28 delivered preterm (26.7%). The Plasma fibronectin concentrations in women with preterm delivery were higher than in those who delivered at term (p = 0.001). Accordingly, Plasma fibronectin concentrations were significantly higher in the second serum samples (p = 0.01). Plasma fibronectin concentrations was also higher in obese women and in those suffering from preeclampsia (p = 0.12) and gestational diabetes (p = 0.81). Conclusion: Plasma fibronectin concentrations test could be used as an optional screening test for preterm delivery at 28 to 34 wk of gestation in pregnant women who prefer to avoid vaginal sampling. Key words: Premature birth, Fibronectin, Maternal serum screening tests.

whole blood samples were obtained from 30 pregnant women at 15 –24 weeks of gestation. DNA was extracted from each plasma or serum sample. To detect the Y-chromosome specific marker DYS14 in the maternal blood, (Polymerase Chain Reaction) PCR were carried out for each DNA extract. The PCR products were analyzed by 1.5% agarose gel electrophoresis and ethidium bromide staining. The results compared with fetal gender after delivery. The result of delivery revealed that 13 pregnant women had a male fetus and the remaining 17 pregnant women had a female fetus and DYS14 was detected in all plasma and serum samples obtained from pregnant women and revealed that 13 pregnant women had a male fetus and the remaining 17 pregnant women had a female fetus. The PCR sensitivity for detecting the gender of fetus from maternal whole blood at 15–24 weeks of gestation was 100% in both plasma and serum, DYS14 was not detected in the DNA from any of the 17 pregnant women carrying a female fetus. The results showed that PCR analysis of maternal plasma and serum can be used to diagnose fetal gender.

Background: Preeclampsia (PE) is a hypertension disorder condition occurring in 7-10% of all pregnancies. Preeclampsia if unidentified and left untreated is associated with poor maternal and fetal adverse outcomes. The objective of the present study was to characterize maternal serum selenium levels as a predictor of preeclampsia and to correlate dietary selenium intake with serum selenium levels in first trimester of pregnancyMethods: A retrospective case-control study of 107 pregnant women was conducted over 1.5 years at St. John’s Medical College Hospital. On screening for inclusion criteria, at baseline, information on maternal socio-demography, anthropometry, dietary intake and clinical examination was collected. A venous blood sample at baseline and 2nd or 3rdtrimester of pregnancy was collected for estimation of selenium concentrations. Blood pressure was measured at baseline and followed up during pregnancy to select cases and controls. Pregnant women were termed ‘cases’ based on NHBPEP (National High Blood Pressure Education Program) classification and subsequent 22 women with normal blood pressure controlled for age were termed as ‘controls.Results: No statistically significant differences were observed for baseline characteristics, biochemical parameters and blood pressure at recruitment among cases and controls. Cases had significant lower levels of energy (P=0.032) and micronutrients like zinc (P=0.027), selenium (P=0.022), magnesium (P=0.047) at first trimester. The serum selenium levels were significantly higher in cases as compared to the controls (69.2±13.7 vs. 59.6±12.9; P=0.021) at baseline.Conclusions: Our findings suggest that serum selenium levels may not be an independent predictor of preeclampsia. Assessment of other micronutrients, oxidative stress markers and other complementary elements may be useful in predicting preeclampsia.
