Aim: to study the activity of the hypoxia marker HIF-1α (hypoxia-inducible factor-1α) in pregnant women with phlebopathy.Materials and Methods. We examined 70 women with phlebopathy in the dynamics of pregnancy. The main group consisted of 30 patients whose newborns had signs of hypoxia; the control group consisted of 40 women with healthy children. All women underwent ultrasound examinations of the veins of the lower extremities and pelvis with an assessment of vascular patency, the condition of the venous valves, and the phenomenon of platelet sludge. The expression of the HIF-1α transcription factor at 18–20 and 36 weeks was performed by real-time PCR.Results. Disorder of veins functional state was found in all pregnant women of the main group, which was accompanied by the formation of platelet sludge of varying degrees in the area of the venous valves in the majority, signs of endothelial dysfunction and venous hypoxia – an increase in the expression of the hypoxia gene HIF1-α by 2.18 times. In the women of the control group the indicators were not violated.Conclusion. The transcription factor HIF1-α can be considered a marker of unfavorable perinatal outcomes in pregnant women with signs of phlebopathy.

The objective: to improve the treatment of placental dysfunction in pregnant women with oligohydramnios regarding their psychological condition. Patients and methods. Survey was conducted in 120 pregnant women with oligohydramnios the gestational age of 27-29 weeks (main group) and 30 physiologically healthy pregnant women (control group) on the basis of the city clinical hospital of Ivano-Frankivsk. Results. During the study of psychological features we have not yet determined significant differences in the level of personal anxiety with oligohydramnios as compared with pregnant women with physiological gestation. Also, was found the division of examined for low, medium, and high levels of this indicator between the two pregnant groups. In particular, approximately half of the individuals had an average level of personal anxiety – 14 (46.67±9.11%) and 57 healthy pregnant women (47.50±4.56%) with oligohydramnios, third – highest, respectively 11 (36.67±8.80%) and 39 (32.50±4.58%), the lowest level recorded in 5 (16.67±6.80 per cent) and 24 (20.00±3.65%) patients. A comprehensive approach to correction of the condition of water shortage has been applied in women of the main group, which included: psychological support for couples with sessions with a psychologist to control emotions. Establishing emotional contact with a woman, trust relationships, discussion of physical and emotional changes is a part of pregnancy. Conclusion. In the result of the researches, the approach proposed by us to the treatment of pregnancy with oligohydramnios, allowed to reduce the stress of compensatory mechanisms of the fetoplacental unit, which contributed to the reduction of anxiety in pregnant and have improved not only obstetric but also perinatal outcomes in women of the main group.

Objectives To evaluate the effect of pravastatin to prevent preeclampsia (PE) in pregnant women at a high risk of developing preeclampsia and the maternal and perinatal outcomes and the sFlt1/PLGF ratio. Study Design This is an open labelled RCT part of INOVASIA trial. Pregnant women at a high risk of developing PE were recruited and randomized into an intervention group (40) and a control group (40). The inclusion criteria consisted of pregnant women with positive clinical risk factor and abnormal uterine artery doppler examination at 10-20 weeks gestational age. The control group received low dose aspirin (80 mg/day) and calcium (1 g/day), while the intervention group received additional pravastatin (20 mg twice daily) starting from 14-20 weeks gestation until delivery. Research blood samples were collected before the first dose of pravastatin and before delivery. The main outcome was the rate of maternal preeclampsia, maternal-perinatal outcomes, and sFlt-1, PLGF, sFlt-1/PlGF ratio and sEng levels. Results The rate of preeclampsia was (non-significantly) lower in the pravastatin group compared with the control group (17.5% vs 35%). The pravastatin group also had a (non-significant) lower rate of severe preeclampsia, HELLP syndrome, acute kidney injury and severe hypertension. The rate of (iatrogenic) preterm delivery was significantly (p=0.048) lower in the pravastatin group (n=4) compared with the controls (n=12). Neonates in the pravastatin group had significantly higher birthweights (2931 + 537 vs 2625 + 872 g; p=0.006), lower Apgar scores < 7 (2.5 vs 27.5%, p=0.002), composite neonatal morbidity (0 vs 20%, p=0.005) and NICU admission rates (0 vs 15%, p=0.026). All biomarkers show a significant deterioration in the control group compared with non significant changes in the pravastatin group. Conclusions Pravastatin holds promise in the secondary prevention of preeclampsia and placenta-mediated adverse perinatal outcomes by improving the angiogenic imbalance.

A functional cervical insufficiency plays an important role in the etiology of miscarriage and premature birth. The aim of research was to estimate the hormonal balance indexes during the course of pregnancy in pregnant women with functional cervical insufficiency and to correct the revealed violations in order to prevent obstetric complications. 101 pregnant women with confirmed diagnosis of a functional cervical insufficiency in term of gestation 22–32 weeks of pregnancy (the main group) and 34 pregnant women and women in labor with physiological condition of the cervix (the control group) were examined. The content of estradiol, progesterone, cortisol and prolactin was examined in the blood serum. On the second stage of examination 63 pregnant women obtained general basic therapy (I main group) and 38 pregnant women (II main group) received a developed treatment complex which included progesterone support by the micronized progesterone 200–400 mg twice a day up to 34–35 weeks of pregnancy, magnesium support by the magnesium orotate dehydrate in the therapeutic dosage and arginine glutamate in the therapeutic dosage. The correction of cervical insufficiency was performed with the help of a cervical pessary (according to indications). The examination of hormonal balance revealed an accurate decease of progesterone concentration on the background of high concentration of estradiol and increased levels of stress-associated hormones. Propitious influence of the developed therapy is proved by increase of progesterone concentration in the blood serum, normalization in stress-associated hormones balance according to gestational age. All this provideded the decrease of specific weight of threatened preterm labors, placental dysfunction, vaginitis, bacterial vaginosis and delay the labors up to 38–39 weeks of gestation in 97,4% of pregnant women (82,5% in the I main group). Prescription of micronized progesterone, magnesium orotate dehydrate, arginine glutamate to pregnant women with a cervical insufficiency is reasonable and effective one comparing with general and traditional therapy.

Врожденные пороки сердца (ВПС) являются ведущей патологией среди всех пороков и аномалий развития плода. Известно, что тератогенный эффект ксенобиотика будет максимально представлен при нарушенных иммунных взаимодействиях в системе мать-эмбрион . Неоднократно показано, что женский гомозиготный генотип HLA-G 3UTR 14-bp ins/ins ассоциирован с репродуктивными потерями. Цель исследования. Изучить распределение аллелей и генотипов генов биотрансформации ксенобиотиков у женщин, имеющих детей с ВПС, носительниц вариантных генотипов HLA-G 3UTR 14-bp ins/del. Материал и методы. Обследованы 103 женщины, у которых дети при рождении имели врожденный порок сердца без хромосомных заболеваний и родословной историей, а также 103 женщины (контрольная группа), родивших двух здоровых детей и более. Типирование полиморфных сайтов генов HLA-G 3UTR 14-bpins/del, GSTM1 (rs74837985), CYP1A1 (rs1048943) CYP1A2 (rs35694136, rs762551) GSTT1 (rs2266633, rs2266637, rs2234953) GSTP1 (rs6591256, rs1695, rs1871042, rs1793068), GATA 6 (rs10454095) проводили методом RT-PCR. Результаты. Показано, что у женщин основной группы, являющихся носительницами гомозиготного генотипа 14-bp ins/ins HLA-G 3UTR, статистически значимо чаще встречались гетерозиготные генотипы GSTP1 (rs6591256) A/G (р0,01 отношение шансов ОШ5,1, 2,5710,27), GSTP (rs1793068) G/T (р0,01 ОШ5,1, 2,5710,27), CYP1A2 (rs762551) A/C (р0,01 ОШ6,81, 3,3513,73) и гомозиготный минорный генотип GSTP1 (rs1871042) T/T (р0,001 ОШ7,32, 3,6214,76) по сравнению с группой контроля. В основной группе женщин G/G rs74837985 GSTM1 статистически значимо реже (р0,01 ОШ 0,20, 0,06-0,59) встречался у носительниц 14-bp ins/ins HLA-G 3UTR по сравнению с носительницами гетерозиготного генотипа 14-bp ins/del HLA-G 3UTR. Заключение. В ходе исследования установлено, что при одновременном носительстве мутантных аллелей HLA-G и генов системы транформации ксенобиотиков риски рождения детей с дефектом межжелудочковой перегородки выше, чем при носительстве изолированных мутаций.Congenital heart defects (CHD) are the leading pathologies among all congenital malformations and fetal development abnormalities. It is known that the teratogenic effect of xenobiotic will be maximally presented in the case of disturbed immune interactions in the mother-embryo system. It has been repeatedly shown that the female homozygous genotype HLA-G 3UTR 14-bp ins/ins is associated with reproductive losses. The purpose of this study was to study the distribution of alleles and genotypes of xenobiotic biotransformation genes in women with children with CHD, carriers of variant HLA-G 3UTR 14-bp ins/del genotypes. Material and method: It was examined 103 women whose children had a ventricular septal defect (VSD) without chromosomal diseases and a pedigree history at birth, and 103 women (control group) who gave birth to two or more healthy children. The typing of polymorphic sites of the genes HLA-G 3UTR 14-bp ins/del, GSTM1 (rs74837985), CYP1A1 (rs1048943) CYP1A2 (rs35694136, rs762551) GSTT1 (rs2266633, rs2266637, rs2234953) GSTP1 (rs6591256, rs1695, rs1871042, rs1793068), GATA 6 (rs10454095) was performed by the RT-PCR method. Mathematical processing was carried out using the application software STATISTICA 8.0 (StatSoftInc., USA) and SNPstats. Results: It was shown that the heterozygous genotypes GSTP1 (rs6591256) A / G (p0.01, OR5.1 (2.5710.27)), GSTP (rs1793068) G / T (p0.01, OR5.1 (2.5710.27)), CYP1A2 (rs762551) A/C (p0.01, OR6.81 (3.3513.73)) and the homozygous minor genotype GSTP1 (rs1871042) T/T (p0.001, OR7.32 (3.6214.76) ) were statistically significantly more frequent in the main group of women who are carriers of the homozygous genotype 14-bp ins/ins HLA-G 3UTR, in comparison with the control group. In the main group of women G/G rs74837985 GSTM1 statistically significantly less (p0.01, OR0.20 (0.060.59)) was found in carriers of 14-bp ins / ins HLA-G 3UTR, in comparison with carriers of the heterozygous genotype 14-bp ins/del HLA-G 3UTR. Conclusion: It was found that with the simultaneous carrier of the mutant alleles of HLA-G and the genes of the xenobiotics transformation system, the risk of having children with VSD is higher, compared with the carriage of isolated mutations.

Introduction During pregnancy, women often change their lifestyle for fear of harmful effects on the child or themselves. In this respect, many women reduce the amount of physical exercise they take, despite its beneficial effects. Objective To determine the duration of labor in pregnant women who completed a program of moderate physical exercise in water and subsequently presented eutocic birth. Methods A randomized trial was performed with 140 healthy pregnant women, divided into an exercise group (EG) (n = 70) and a control group (CG) (n = 70). The women who composed the study population were recruited at 12 weeks of gestation. The intervention program, termed SWEP (Study of Water Exercise during Pregnancy) began in week 20 of gestation and ended in week 37. Perinatal outcomes were determined by examining the corresponding partographs, recorded by the Maternity Service at the Granada University Hospital Complex. Results The intervention phase of the study took place from June through October 2016, with the 120 women finally included in EG and CG (60 in each group). At term, 63% of the women in EG and 56% of those in CG had a eutocic birth. The average total duration of labor was 389.33 ± 216.18 min for the women in EG and 561.30 ± 199.94 min for those in CG, a difference of approximately three hours (p < 0.001). Conclusions The women who exercised in water during their pregnancy presented a shorter duration of labor than those who did not. The difference was especially marked with respect to the duration of the first and second stages of labor.

The transcription factor hypoxia-inducible factor (HIF) mediates adaptation to hypoxia. We found that HIF regulates the autophagy protein ATG9A in intestinal epithelial cells. Subsequent knockdown of ATG9A resulted in tight junction mislocalization and cytoskeletal defects. These results suggest a link among the hypoxia response, autophagy, and junctional biogenesis.

e17530 Background: It is believed that hypoxia-inducible factor (HIF-1α) hyperactivity promotes synthesis of protective factors and increases bacterial growth-inhibitory activity, provides enhancement methods of the congenital immune response to microbial infection. Methods: Lactoferrin and α-defensin were detected in saliva of 41 patients with oral mucosa (OM) cancer (T2N0-2M0) before a comprehensive treatment; enzyme immunoassay (EIA) method was used. A level of hypoxia-inducible factor (HIF-1α) was evaluated by EIA method in tumor tissues after surgical treatment. The patients were divided into two groups according to an after-surgery period: the main group (n = 16) had after-surgery suppurative complications. An after-surgery period proceeded without infectious complications in patients of a control group (n = 25). Results: It was found that Lactoferrin content in saliva statistically was significantly higher by 36,4% (p < 0,05) (3,0±0,24 µg/ml against 2,2±0,19 µg/ml) if to draw a comparison between the main group and the control group with respect to development of suppurative complications and absence of a inter-group difference according to α-defensin concentration (4,1±0,35 pg/ml against 3,8±0,19 pg/ml). HIF-1α expression index in the main group (8,4±0,79 CU/mg protein in a well) exceeded this index by 18,3% (p < 0,05) in the control group (7,1±0,79 CU/mg protein). A positive correlation between HIF-1α expression and Lactoferrin content (R = 0,53 at р = 0,0001) was detected in patients with OM cancer. Conclusions: Detected HIF-1α hyperexpression in tumor tissues and Lactoferrin content in saliva, as well as their interaction allows suggesting significance of these factors for their progression prediction in patients with OM cancer in case of after-surgery suppurative complications.

Abstract BackgroundMaternal undernutrition is critical in the etiology of poor perinatal outcomes and accounts for 20% of small-for-gestational-age (SGA) births. High levels of food insecurity, antenatal undernourishment and childhood undernutrition necessitate the supplementation of fortified balanced energy-protein (BEP) during pregnancy in low-income settings especially with scarce literature available in this subject. Hence, this paper extensively covers the protocol of such a trial conducted in an urban slum of Karachi, Pakistan. Methods The trial is community-based, open-labelled, four-arm, and randomized controlled that will include parallel group assignments with a 1:1:1:1 allocation ratio in low-income squatter settlements in urban Karachi, Pakistan. All pregnant women (PW), if identified between > 8 and <19 weeks of gestation based on ultrasound, will be offered routine antenatal care (ANC) counseling and voluntary participation in the trial after written informed consent. A total number of 1836 PW will be enrolled with informed consent and randomly allocated to one of the four arms receiving: (1) ANC counseling only (control group), (2) ANC counseling plus BEP supplement (intervention arm 1), (3) ANC counseling plus BEP supplement plus 2 doses Azithromycin (intervention arm 2), or (4) ANC counseling plus BEP supplement plus daily single dose of Nicotinamide and Choline (intervention arm 3).

Adaptive Reactions

According to modern data, the cardiovascular system is a kind of indicator of the organism's adaptive activity, and the structure of the heart rhythm carries information about the development of adaptive reactions in response to irritating factors of the external and internal environment.The aim of the study – to investigate the functional state of the autonomic nervous system in pregnant women who have harmful habits by evaluating and analyzing the parameters of heart rate variability in order to prevent complications of non-delivery of gestational process.Materials and Methods. The study involved 73 pregnant women, 53 of them were pregnant (the main group) who had malignant habits in history. Before studying adaptive reactions in pregnant women, a study of cardiac rhythm variability was performed in practically healthy non-pregnant women of reproductive age (25.3±2.2) years). The control group consisted of 20 pregnant women without any harmful habits. Determination of heart rate variability was performed on the basis of peripheral heart rate recording, which included measuring the sequence of RR intervals for 5 minutes, followed by mathematical analysis using the PlsMntr software product.Results and Discussion. It was established that in the main group, in the complicated failure to pass the gestational process, violations of cardiac rhythm variability were detected in 59.7 % of cases. There is an increase in the frequency of very low frequency (VL F) waves (43.5 % relative to control, p<0.05), indicating a predominance of humoral and metabolic rate of regulation of the cardiac rhythm. At the threat of premature births, a decrease in the particle (LF) is observed at 36.6 %, a decrease in the share of high-frequency waves (НF) by 30.8 %. Taking into account the results of the study, one can speak of a decrease in the tone of the sympathetic and parasympathetic nervous system, reducing the influence of the reflexive vegetative level of regulation, which, in turn, indicates the depletion of regulatory mechanisms and the lack of an adaptive protective effect of n.vagus on the heart.Conclusions. Our innovative low-invasive method of evaluating the adaptive reactions of the organism through the determination and analysis of indicators of cardiac rhythm variability in pregnant women with the existing harmful habits offers us the opportunity to observe manifestations of functional stress of regulatory systems of pregnant women, preceding the development of complication of non-delivery of gestational process.

The aim of the work is to assess the effects of cytomegalovirus infection on the 20α-hydroxysteroid dehydrogenase activity in the villous chorion syncytiotrophoblast in the first trimester of pregnancy. The materials for the study included 48 villous chorions samples taken during spontaneous abortions at 8th–10th weeks of gestation from women with reactivation of cytomegalovirus infection (the main group). The control group included 35 villous chorions samples from pregnant women with chronic cytomegalovirus infection in the latent stage taken at medical abortions at the same stage of gestation. The results of women’s examination were studied taken into account the activity of cytomegalovirus infection by immunoassay by detection of IgM antibodies or by 4 times and more increase of IgG antibody titers in the paired serums in dynamics in 10 days. The activity of 20α-hydroxysteroid dehydrogenase was assessed by the histochemical method. Quantitative evaluation of the reaction products was carried out on sections under the microscope MT (Japan) connected to software-hardware complex «SCION Corporation» (USA). At histochemical specimen of villous chorion of pregnant women who had a reactivation of cytomegalovirus infection during pregnancy (main group), there was a decrease of cytophotometric parameter of 20α-hydroxysteroid dehydrogenase activity till 30.1±2.12 pixels/μm2 (p<0.001) compared with the control group. The decrease in the reaction activity in syncytiotrophoblast indicated a decrease in the contents of 20α-dihydroprogesterone in placenta, which contributed, in our opinion, to spontaneous abortion.
