The thyroid gland pathology is one of the most common in the world and is on the samelevel with diabetes mellitus and diseases of the cardiovascular system in its importance.Extragenital pathology, in particular, nodular goiter in pregnant women acts as anadditional stress factor that can negatively affect hormonal relationships in the motherplacenta-fetus system and contribute to an increase in the frequency of complications ofpregnancy, childbirth, and impairment of the fetus and newborn condition.The aim of this work – to study the disturbance effect in the hormonal function of theplacenta on the condition of the fetus and newborn from women with nodular goiter.Material and methods. The analysis of the state of the fetus and newborn of 20 apparentlyhealthy women (control group) and 54 women with nodular goiter (main group). Of these,30 newborns from women with grade I nodular goiter were included into group I, and24 newborns from women with grade II nodular goiter were included into group II. Theintrauterine fetus state was judged about according to the data of cardiotocography, fetalbiophysical profile (FBP), ultrasound examination, and Doppler results. The functionalstate of the fetoplacental complex was assessed by determining the serum concentrationof estradiol (Е2), estriol Е3), progesterone, placental lactogen, as well as the results ofhistological examination of the placentas.Results. The study of the placenta hormonal function, the results of ultrasound diagnosticsand histological examination of the placentas indicate the presence of placentaldysfunction in pregnant women with nodular goiter, that affected the condition of thefetus and newborn. Thus, the cardiotocographic index in fetuses from pregnant women,suffering from nodular goiter, is significantly less than in healthy pregnant women(p<0.05). The average PPI score in women with nodular goiter is also significantly lowerthan in the control group (p<0.05). Doppler data indicate a change in the parameters of the maternal hemodynamics, that led to a violation of the uteroplacental blood flow, thedevelopment of fetal hypoxia.Conclusions. The presence of nodular goiter in the mother is a risk factor for placentaldysfunction. Starting from the second trimester of pregnancy, there are significant changesin the content of placental hormones in the blood. A decrease in the concentration ofprogesterone in the blood serum in pregnant women with nodular goiter, in the latestages of pregnancy, can serve as a marker of the threat of termination of pregnancyand premature birth. A decrease in the content of estradiol and placental lactogen inthe maternal blood serum can be used as a marker of fetal distress in pregnant womenwith nodular goiter. The condition of the fetus and newborn is in direct proportion to thedegree of manifestation of the nodular goiter and the functional state of the placenta.

Objective: In order to improve the detection rate of fetal hypoxia in the third trimester and reduce the probability of adverse pregnancy outcome, color doppler ultrasound (CDU), and contractions were used to assess the severity of fetal hypoxia. Methods: The 61 pregnant women diagnosed with intrauterine hypoxia in South District of The Affiliated Hospital of Chengde Medical College from October 2017 to September 2019 were classified as the sick group. Meanwhile, the 61 normal pregnant women were selected as the control group. CDU was used to detect the relevant indexes of umbilical artery (UA) and middle cerebral artery (MCA) in the two groups, including pulse index (PI), resistance index (RI), systolic peak blood flow velocity (S) and diastolic peak blood flow velocity (D). The Apgar scale was used to score neonatal status. According to the score results, newborns were divided into Apgar ≤ 7 group and Apgar > 7 group. The indexes of UA and MCA were compared between the two groups. The amniotic fluid status of pregnant women was assessed using the contractile stimulation test (CST). The rate of amniotic fluid pollution in pregnant women and the incidence of neonatal asphyxia were calculated. Pregnant women were grouped according to the CST score. The correlation between CST score and amniotic fluid pollution and neonatal asphyxia in pregnant women was analyzed. Results: First, the index of fetal UA was obviously higher than that of the control group, while the index of MCA was obviously lower than that of the control group (P < 0.05). Second, the indexes of fetal UA in Apgar ≤ 7 group were obviously higher than those in Apgar > 7 group, while those in MCA were obviously lower than those in Apgar > 7 group (P < 0.05). Third, the incidence of amniotic fluid pollution and neonatal asphyxia in low and middle groups of pregnant women was obviously higher than that in high groups (P < 0.01). Conclusion: This indicates that the CDU technology combined with uterine contraction stimulation experiment can assess the degree of intrauterine hypoxia in the late stage of pregnancy, which provides a feasible scheme for clinical detection of intrauterine hypoxia.

The objective: study of hormonal status in pregnant women with benign cervical pathology (CP) in anamnesis. Patients and methods. Clinical and statistical analysis of the hormonal status of 100 women with a history of benign CP pathology has been performed. According to the revealed symptoms of CP during colposcopic examination, women were divided into two groups: 100 pregnant women, in whom colposcopic and cytologically signs of CP pathology were not detected, were included in the control group; and 100 women who had a pathology of CP, entered the main group. Results. The study examined hormonal relationships in the system mother–placenta–fetus, namely the level of hormones such as estriol, progesterone, human chorionic gonadotropin, placental lactogen. Hormonal changes in pregnant women and contribute to reducing the immunoreactivity unwanted stimulation of existing benign hyperplastic background processes in the cervix. Conclusion. Determining functional state placenta is an important factor in the timely diagnosis of disorders in the functioning of the system mother–placenta–fetus. Key words: hormonal status, placenta, uterine cervix, fetoplacental complex.

Iodine deficiency is an important clinical and public health problem. Its prevention begins with an adequate intake of iodine during pregnancy. International agencies recommend at least 200 μg iodine per d for pregnant women. We assessed whether iodine concentrations in the amniotic fluid of healthy pregnant women are independent of iodine intake. This cross-sectional, non-interventional study included 365 consecutive women who underwent amniocentesis to determine the fetal karyotype. The amniocentesis was performed with abdominal antisepsis using chlorhexidine. The iodine concentration was measured in urine and amniotic fluid. The study variables were the intake of iodized salt and multivitamin supplements or the prescription of a KI supplement. The mean level of urinary iodine was 139·0 (sd94·5) μg/l and of amniotic fluid 15·81 (sd7·09) μg/l. The women who consumed iodized salt and those who took a KI supplement had significantly higher levels of urinary iodine than those who did not (P = 0·01 andP = 0·004, respectively). The urinary iodine levels were not significantly different in the women who took a multivitamin supplement compared with those who did not take this supplement, independently of iodine concentration or multivitamin supplement. The concentrations of iodine in the amniotic fluid were similar, independent of the dietary iodine intake. Urine and amniotic fluid iodine concentrations were weakly correlated, although the amniotic fluid values were no higher in those women taking a KI supplement. KI prescription at recommended doses increases the iodine levels in the mother without influencing the iodine levels in the amniotic fluid.

OBJECTIVE: Pre-eclampsia is a placental disease of unknown cause. Maternal circulating concentrations of a number of protein markers are altered (mainly increased) in pre-eclampsia in comparison with controls of matched gestational age. Inhibin A and activin A were found to be elevated even before the onset of the disease. The aim of this study was to compare the levels of inhibin A, activin A: follistatin ratio, leptin, pregnancy-associated plasma protein-A (PAPP-A), human placental lactogen (HPL), placenta growth factor (PLGF) and pregnancy-specific beta1-glycoprotein (SP1) in placental extracts of normal pregnant women and pre-eclampsia patients at term. METHODS: Placental tissue from normal pregnancies (n=14) and patients with pre-eclampsia (n=13) were collected at term (> or =37 weeks of gestation) and stored at -80 degrees C. The frozen tissue pieces were homogenised and the above-mentioned proteins were measured by specific enzyme-linked immunosorbent assays. RESULTS: Placental contents of inhibin A and PAPP-A were significantly higher (P<0.05) in pre-eclampsia placental extracts compared with the controls. Activin A:follistatin ratio was higher (23) in pre-eclampsia extracts than in the controls (15). Leptin, PLGF, SP1 and HPL levels were not altered in the term pre-eclampsia placenta. Inhibin A and PAPP-A contents were increased in the placental extracts of pre-eclampsia patients. CONCLUSION: Our data suggest that the placenta, possibly by a compensatory mechanism, is at least in part responsible for the altered serum levels observed in pre-eclampsia.

Morphological Research

The study of the fetoplacental complex and the morphological research of placenta of 50 pregnant women with hyperandrogenism were conducted by the ultrasonic method, dopplerometry and cardiotocography. It was shown that hyperandrogenism causes destructive and neonatal adaptation changes of placenta leading to its dysfunction. The high frequently of occurrence of complications in the gestational process at late diagnostics of hyperandrogenism (during pregnancy) was observed.
