Introduction: The search for a statistically significant link between sFasL and their potential regulators MMP-2 is necessary to optimize the tactics of managing and treating pregnant women with perinatal infections. The aim: To determine the level of MMP-2 in pregnant with perinatal infections and its role in the development of placental dysfunction. Materials and methods: The study involved examination of 230 pregnant, who were divided into 3 groups (60 people each): Group I with viral (CMV, HSV-1,2,6 types), Group II with bacterial (chlamydia, ureaplasma, mycoplasma) and Group III with mixed infection. Group IV was the control one, and included 50 pregnant with a physiological course of pregnancy. The study implied determination of serum levels of MMP-2 and sFasL, the level of caspase-3 in the placenta, ultrasound was performed by the MINDRAY M7 (China) scanner. The data obtained were statistically processed using the STATISTICA software. Results: Pregnant women with perinatal infection were found to have a significant increase in sFasL and caspase-3 levels in all the studied groups as compared to corresponding values in the control group (Kruskal-Wallis test, p<0.001). In all groups of pregnant women with perinatal infection the level of MMP-2 in serum was elevated with respect to control values approximately 3-4 times (Kruskal-Wallis test, p <0.05). According to ultrasound data, hypoplasia of placenta was observed in (46.6 ± 6.4)% of cases in Group І and in (30 ± 6.4)% in Group ІІІ. In Groups II and III, placental hyperplasia was detected in (20 ± 5.2)% and (26 ± 5.7)% of cases, respectively. Conclusions: The findings showed that secondary to the impact of perinatal infection among a number of indices in the peripheral blood of pregnant women, a significant role is played by an increase in levels of MMP-2 and sFasL. These indices reflect and determine the induction of apoptotic response from the placenta in this category of pregnant women. The revealed increase in caspase-3 level means that pregnant women with perinatal infections undergo caspase cascade of apoptosis in placental cells. Thus, the obtained results indicate that pregnant women with perinatal infections develop an increase in the level of MMP-2 and activation of the Fas-dependent signaling pathway of programmed cell death, which leads to the launch of a caspase cascade of apoptosis in placental cells. An increase in the loss of placental cells due to apoptosis may be one of the key factors triggering the development of placental dysfunction and, as a consequence, unfavorable conditions for fetal development.

The pleiotropic effects of vitamin D (VD), whose active form is synthesized in the kidneys, play a certain role both in forming and functioning the feto-placental system, including various pregnancy complications. The aim of the study was to evaluate the vitamin D status in pregnant women with placental dysfunction (PD) and chronic inflammatory kidney disease (CIKD). During 24–34 pregnancy weeks, 56 pregnant women with PD were examined (main group ‒ I); 24 patients (42.85 %) had chronic pyelonephritis (group IA). The control group (group II) had 31 conditionally healthy pregnant women. The total VD level in the blood was determined by ELISA; in addition to the general clinical standard examination, the urine also underwent bacteriological examination. The VD mean level in pregnant women with PD and CIKD was significantly lower than that in the control group (31.08 ± 7.2 and 45.42 ± 9.67 ng/ml (p <0.01)). Only 33.33 % of pregnant women in group IA had a VD optimum, as well as 93.55 % (p < 0.01) in the control group and 17.86 % in group I. 8.33 % of pregnant women had a VD deficiency in group IA (RR = 2.09; CI 95 % ‒ 1.8‒2.42). The patients with a VD-deficiency were absent in the control group. 58.33 % of women in group ІА had a suboptimal VD level and 6.45% in the control group (RR = 3.57; CI 95 % ‒ 1.62‒7.88). Bacteriuria was observed in all pregnant women with a VD-deficient or suboptimal level. At the optimum VD level, bacteriuria was diagnosed twice less (χ2 = 66.67; p <0.01). In patients with an inadequate VD level, CIKD was diagnosed 3.8 times more (RR = 3.57; CI 95 % ‒ 1.62‒7.88). 494 Proceedings of the National Academy of Sciences of Belarus. Medical series, 2020, vol. 17, no. 4, pp. 493–499 A significantly calcitriol reduction in pregnant women with placental dysfunction suggests that the deficiency or the suboptimal level of vitamin D and inflammatory kidney diseases may be the interdependent processes that play a decisive role in the formation of placental dysfunction.

The high prevalence of the vitamin D (VD) deficiency states (VDDS) among adults, as well as the data on the pleiotropic effects of calcitriol suggests its participation in the development of various complications and pregnancy outcomes. The objective of the present study is to analyze the pregnancy course and delivery tactics of pregnant women with placental dysfunction (PD) depending on the calcitriol availability. We examined 56 patients with PD (I – main group) and 40 conditionally healthy women with physiological pregnancy (II – control group). In addition to the standard clinical and laboratory examination, the level of vitamin D in the blood was determined by ELISA. The statistical analysis used the software Biostat, Statistica 6.0. In 76.8 % of group I women, the VD content corresponded to the deficit (38.4 %) and to the suboptimal status (38.4 %), (RR = 3.0; 95 % CI 2.39–3.76). In group II, VDDS was not detected and the suboptimal status was diagnosed in 31.45 %. The average VD level in group I was significantly lower than that in group II (31.4 ± 8.6 ng/ml vs 43.54 ± 11.2 ng/ml; Uemp = 42.5; p < 0.05). The caesarean section rate in group I was 3.4 times higher than that in group II (42.85 % vs 12.5 %; F = 0.00001; p < 0.01). The weight of newborns in group II significantly exceeded the weight of children in group I (3643.24 ± 136 g vs 3299.11 ± 128 g; t = 4.17; p < 0.01); a strong direct correlation was found between the weight of the newborn and the VD level in the blood of pregnant women (r = 0.71). VDDS increases 2 times the risk of abdominal delivery (RR = 1.27; 95 % CI 0.95–1.66). The VD status of a pregnant woman can have a certain influence on the formation of optimal adaptive-compensatory mechanisms in the utero-placental-fetal system and on the pregnancy outcome for mother and fetus.

Women are more at risk to stress in pregnancy than during the puerperium. One method of coping with stress is through physical exercise. Maryam Exercise can be used as an alternative to the development of pregnancy exercises in Indonesia because it covers the holistic aspects and easy to do. It is a combination of basic pregnancy exercises, Islamic prayer (Salat) movements and dhikr.  The purpose of this study was to examine the impact of Maryam exercise on the stress levels and cortisol serum levels among primiparous pregnant women. This study used a quasi-experimental study design, pre-test and post-test with non-equivalent control group. In the third trimester of 40 primiparous women  were randomly assigned into two groups such the experimental group (n=20) and the control group (n=20). The experimental group received the Maryam exercise while the control group received the standard antenatal exercise. There was a significant difference in stress levels between the intervention group and the control group before and after receiving the intervention (p <0.05). The cortisol levels also showed the significance difference between the intervention group and the control group before and after receiving the intervention (p <0.05). The findings of this study suggest that Maryam Exercise has a positive impact on stress levels and cortisol serum levels of primiparous pregnant women.

In the present study, we explored SA’s activity against DOX-induced cardiotoxicity and revealed its underlying mechanisms. Male Wistar rats (weight, 190-210g; n=6) were randomly divided into four groups: group I, normal control; group II, DOX 15 mg/kg via intraperitoneal (ip) route; group III, administered DOX+SA 20 mg/kg; and group IV, administered DOX+captopril (CAP 30 mg/kg). SA and CAP were administered orally for seven days, and DOX (15 mg/kg) was injected intraperitoneally an hour before SA treatment on the fifth day. Forty-eight hours after DOX administration, animals were anesthetized and sacrificed for molecular and histology experiments. SA significantly mitigated the myocardial effects of DOX, and following daily administration, it reduced serum levels of lactate dehydrogenase (LDH) and creatine kinase isoenzyme-MB to near normal values. Levels of oxidative stress markers, glutathione-peroxidase, superoxide dismutase, and catalase, in the cardiac tissue were significantly increased, whereas malondialdehyde levels decreased after SA treatment in DOX-administered rats. Furthermore, DOX caused an inflammatory reaction by elevating the levels of proinflammatory cytokines, tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and endothelin- (ET-) 1, as well as nuclear factor kappa-B (NF-κB) expression. Daily administration of SA significantly repressed TNF-α, IL-1β, ET-1, and NF-κB levels. caspase-3 and Bax expression, bcl-2-like protein and caspase-3 activities and levels. Overall, we found that SA could inhibit DOX-induced cardiotoxicity by inhibiting oxidative stress, inflammation, and apoptotic damage.

The objective: frequency decrease perinatal pathologies at women after ART on the basis of studying clinical-ehografical, endocrinological, biochemical, dopplerometrical, cardiotokografical and morphological researches, and also improvement of algorithm of diagnostic and treatment-and-prophylactic actions. Patients and methods. The work basis is made spent by us from 2012 on 2015 by complex inspection of 300 pregnant women from which 250 were after ART and 50 – firstlabours which pragnency without ART, and also their newborns. For the decision of an object in view of research spent to two stages. At 1 stage spent prosperctive research which included 150 pregnant women: з them 100 women pregnancy at which has come out ART (1 group) and 50 healthy women (control group). At 2 stage spent prospective randomization in which result of patients after ART have divided on two equal groups by therapy principle: 2 basic group - 75 pregnant women after ART at which used the algorithm improved by us; 3 group of comparison - 75 pregnant women after ART which have been spent on the standard treatment-and-prophylactic actions. Results. The results suggest that women after using ART is a high frequency of reproductive losses in the first trimester (10.0%), 3.0% of spontaneous abortion from 16 to 22 weeks, and 3.0% "early" premature delivery (22 to 28 weeks of pregnancy). The frequency of violations of the functional state of placenta in women after using IVF is 63.0%, which is the main cause of high levels of perinatal losses (40.0 ‰), and delivery by cesarean section (96.0%). Placental dysfunction in women after using ART characterized by retrohorialnyh hematoma (21.0%); size mismatch fruit (30.0%) and hypertonicity of the uterus (73.0%) against changes in fruit-placental blood flow - increased resistance index in umbilical artery and increased vascular resistance in the uterine arteries. Endocrinological and biochemical changes in placental dysfunction in women after using IVF starting from 28 weeks of pregnancy and are in significant reduction in progesterone, placental b1-microglobulin, B2-microglobulin of fertility and trophic в-glycoprotein. Conclusion. The received results: use of the algorithm of diagnostic and treatment-and-prophylactic actions improved by us allows to lower frequency of spontaneous interruption of pregnancy till 22 weeks – from 13.0% to 5.7%; «early» premature birth – from 3.0% to 1.0%; placentary dysfunction from 63.0% to 40.6%; cesarean sections – from 96.0% to 56.5%, and also perinatal losses – from 40.0‰ to 16.2‰. Key words: pregnancy, childbirth, auxiliary reproductive technologies.

There is evidence that high circulating levels of IL-6 and IL-8 are markers of a poor prognosis in various types of cancer, including NB. The participation of these cytokines in the tumor microenvironment has been described to promote progression and metastasis. Our objective was to evaluate the prognostic role of genetic polymorphisms and serum levels of IL-6 and IL-8 in a cohort of Mexican pediatric patients with NB. The detection of the SNPs rs1800795 IL-6 and rs4073 and rs2227306 IL-8 was carried out by PCR-RFLP and the levels of cytokines were determined by the ELISA method. We found elevated circulating levels of IL-8 and IL-6 in NB patients compared to the control group. The genotype frequencies of the rs1800795 IL-6 and rs4073 IL-8 variants were different between the patients with NB and the control group. Likewise, the survival analysis showed that the GG genotypes of rs1800795 IL-6 (p = 0.014) and AA genotypes of rs4073 IL-8 (p = 0.002), as well as high levels of IL-6 (p = 0.009) and IL-8 (p = 0.046), were associated with lower overall survival. We confirmed the impact on an adverse prognosis in a multivariate model. This study suggests that the SNPs rs1800795 IL-6 and rs4073 IL-8 and their serum levels could be promising biomarkers of a poor prognosis, associated with overall survival, metastasis, and a high risk in Mexican children with NB.

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.

Background: An in-depth study of dismetabolic mechanisms in the genesis of pre-eclampsia (PE) has been updated because pregnancy is considered as a natural model of metabolic syndrome (MS), as well as the metabolic disorders are important in development of essential hypertension.Aims: to reveal clinical and laboratory parallels in pregnancy complicated by PE without MS and pregnancy proceeding on the background of MS to assess the role of metabolic disturbances in the development of PE.Materials and methods: 82 women with MS were examined in the dynamics of pregnancy and were divided into 2 groups depending on the implementation of PE: group I consisted of 50 women with PE on the background of MS, group II 32 women with MS without PE. We formed group III consisting of 44 pregnant women with PE without accompanying diseases to assess the pathogenetic value of metabolic disorders in the development of PE. The IV (control) group consisted of 30 healthy women with physiological pregnancy. Metabolic, hematological parameters, hormones, markers of the proinflammatory state, endothelial hemostasiological dysfunction, decidualization and placental angiogenesis, accumulation dynamics and distribution loci of adipose tissue were determined in all pregnant women.Results: In the groups of pregnant women with PE, changes similar to MS were revealed: pronounced diabetic and atherogenic disorders with the development of pathological insulin resistance, hyperinsulinemia and leptinemia, endothelial-platelet link hyperactivation, thrombotic and inflammatory status, visceral type of fat deposition, hyperuricemia, hypersympathicotonia. It is proved that in the hierarchy of mechanisms of PE formation, placental dysfunction is a secondary alteration factor, which additionally potentiates the insulin resistance increase and the effects of structural and functional destabilization of the vascular endothelium.Conclusions: The direction of metabolic changes during pregnancy, the common development of PE and MS indicate the important role of dismetabolic mechanisms in the formation of PE.

Introduction: During pregnancy in the body of a healthy woman there are physiological and psychological changes that contribute to the bearing a child and prepare the female for future labour and motherhood. In women who experience failure at the stage of fertilization or during pregnancy, as a result of prolonged negative emotional states, psycho-emotional stress develops. The aim of the research was to study the psycho-emotional state of women with infertility in history, whose pregnancy resulted from extracorporal fertilization (IVF), and to develop methods for reducing their anxiety. Materials and methods: At the first stage, the initial psycho-emotional state of 60 women in the second trimester, whose pregnancy resulted from IVF (Group I), was studied; the control group consisted of 20 healthy women with a physiological course of pregnancy (Group II). At the second stage, 10 art therapy exercises with a requestioning of pregnant women from Group I were conducted for improving their psycho-emotional state. Results: Women of Group I had a high level of both situational anxiety (SA) and the personal one (PA). The prevalent type of the psychological component of gestational dominant was anxiety and euphoric types (58.3%). In one third of women with burdened gynecological history examined mild or masked depression was diagnosed. 43 pregnant women from Group I used a method of psychocorrection – art therapy, which included colouring “antistress” pictures of perinatal topic, making flowers from paper and creating a collage of dreams. Conclusions: After the art therapy course, a high level of SA (from 46.5% to 7.0%) and OA (from 48.8% to 32.6%) decreased, the index of the optimal type of the psychological component of gestational dominant increased from 25.6% to 53.5%. The number of women without depression increased from 62.8% to 93%.
