A retrospective analysis was carried out according to the archival material of the center of perinatology and pediatric cardiac surgery in Almaty for 2017-2018. The analysis was carried out in 2 groups: the main group - 250 histories of women giving birth after IVF and the comparative group - 250 histories of women giving birth to spontaneous pregnancy. The condition of the feto-placental complex was assessed by studying the data of ultrasound, Dopplerometry, CTG, histological examination. The study shows that in women after the use of ART, the absence of pronounced blood flow disorders in the mother-placenta-fetus system according to Dopple-rometry is important and significant, which contributes to the favorable course of pregnancy and the state of the fetus, as well as the presence of morphological signs of placental insufficiency in 68% of cases inflammatory changes in the placenta in 57% of cases of varying severity.

Aim. To study the peculiarities of placental structure and the state of utero-placental and fetal-placental blood flow in fetal growth restriction.Methods. A prospective study of 50 pregnant women admitted to the department of pathology of pregnancy with fetal growth restriction followed by a retrospective analysis of the obtained data considering risk factors and clinical course of the pregnancy and the results of morphological examination of afterbirth. For the diagnosis of fetal growth restriction ultrasound and Doppler ultrasound of blood flow in the uterine arteries and umbilical artery, and cardiotocography were performed.Results. The most informative sonographic markers of the critical state of the fetus in case of fetal growth restriction are abnormal blood flow indicators of «mother-placenta-fetus» system (critical blood flow disorder in uterine arteries and umbilical artery grade III, blood flow disorder in the medial cerebral artery of the fetus), and also significant hypamnion and changes in placenta combined with poor results of cardiotocography. Obtained data correlated with the results of morphological examination of aftherbirth. Impaired blood flow and significant hypamnion on ultrasound indicate acute placental insufficiency, suggest poor fetal condition, including antenatal death. Petrifaction, infarction and calcification on ultrasound point to chronic placental insufficiency and compensated fetal condition, and they correlate with more favorable perinatal outcomes.Conclusion. The findings of the study demonstrated that ultrasound, Doppler, clinical laboratory and subsequent morphological examination provide very detailed information about the state of placental structure and need for urgent care.

Near Infrared Spectrometry

<p><strong>Introduction:</strong> Clear guidelines for red cell transfusion during cardiac surgery have not yet been established. The current focus on blood conservation during cardiac surgery has increased the urgency to determine the minimum safe hematocrit for these patients. The aim of this study was to determine whether monitoring of cerebral regional oxygen saturation (rSO<sub>2</sub>) via near-infrared spectrometry (NIRS) is effective for assessing the cerebral effects of severe dilutional anemia during elective coronary arterial bypass graft surgery (CABG).</p><p><strong>Methods:</strong> The prospective observational study involved patients who underwent cerebral rSO<sub>2</sub> monitoring by NIRS during elective isolated first-time CABG: an anemic group (<em>N</em>=15) (minimum Hemoglobin (Hb) N=15) (Hb &gt;8 g/dL during CPB). Mean arterial pressure (MAP), pump blood flow, blood lactate level, pCO<sub>2</sub>, pO<sub>2</sub> at five time points and cross-clamp time, extracorporeal circulation time were recorded for each patient. Group results statistically were compared.</p><p><strong>Results:</strong> The anemic group had significantly lower mean preoperative Hb than the control group (10.3 mg/dL versus 14.2 mg/dL; <em>P</em> = .001). The lowest Hb levels were observed in the hypothermic period of CPB in the anemic group. None of the controls exhibited a &gt;20% decrease in cerebral rSO<sub>2</sub>. Eleven (73.3%) of the anemic patients required an increase in pump blood flow to raise their cerebral rSO<sub>2</sub>.</p><p><strong>Conclusions:</strong> In this study, the changes in cerebral rSO<sub>2</sub> in the patients with low Hb were within acceptable limits, and this was in concordance with the blood lactate levels and blood-gas analysis. It can be suggested that NIRS monitoring of cerebral rSO<sub>2</sub> can assist in decision making related to blood transfusion and dilutional anemia during CPB.</p>

Abstract Based on archival material and interviews, the paper argues that the autonomy of Hong Kong's institutions of higher education has varied since 1911, with the colonial state initially exercising tight control and relaxing it especially as the transfer of sovereignty over Hong Kong approached. China has sought to reassert control especially since 2014 in what continues to be contested space.

At the end of the sixteenth and the beginning of the seventeenth centuries the Celali revolts resulted in wide-scale destruction throughout the entire Anatolian region. While research has been done on the general effects of this destruction, in-depth work investigating the economic consequences of the Celali revolts based on extant economic data has yet to be undertaken. Using archival material it is, however, possible to show the economic effects of these revolts. Taking the fall in tax collected by the state from the population as a result of the Celali revolts, this article aims to show how these revolts affected the economic structure of the state. By comparing the levels of avarız taxes collected before and after the revolts, and by trying to establish the levels of tax set according to the tax unit, the avarız hanes, the article thus sets out the economic impact the revolts had in Anatolia.

Inflammatory Changes

Hypothesis/aims of study: Infection of the amniotic cavity and placenta is one of the leading causes of adverse pregnancy outcomes. In the majority of cases, intra-amniotic infection is associated with the normal microbiota of the lower urogenital tract. The aim of the study was to explore the relationships between the placental inflammatory changes, vaginal microbiota and labor course. Study design, materials and methods: We examined 124 women at 37-41 weeks of gestation. The vaginal discharge at admission was taken for microbiological evaluation, with the delivered placenta sent for histological examination. Results: In 17.7% of cases, histological examination of the placenta revealed inflammatory changes. A statistically significant correlation was noted between the placental inflammatory changes and Staphylocossus spp. presence in the vaginal discharge at admission (р = 0.0004). The placental inflammatory changes were associated with the membrane rupture to delivery interval more than 6 hours (р = 0.01) and the labor duration more than 7 hours (р = 0.0004). Prelabor rupture of membranes did not significantly affect the placental inflammatory changes (p = 1.0). Conclusion: Predisposing factors for the development of ascending bacterial infection of the placenta are an abnormal vaginal microbiota with the presence of opportunistic bacteria before delivery, a long membrane rupture to delivery interval, and a prolonged labor.
