Background: Gestational diabetes mellitus (GDM) is defined as any degree of dysglycaemia that occurs for the first time or is first detected during pregnancy. The adverse effects of GDM on pregnant women are pre-eclampsia, PIH, PPH, polyhydramanios, PROM, meanwhile, there would be an increase in dystocia, birth injury, and cesarean sectionMethods: This retrospective study was conducted in a Gynecology clinic in District Shivpuri to find out the various risk factors for GDM and to evaluate the impact of GDM on maternal and fetal health during the antenatal period. 84 patients who were diagnosed with GDM were included in the study. Results: Among risk factors; BMI >25 kg/m2 before pregnancy was found in 15.47% of the case, family history of diabetes mellitus 8.33%, Previous history of macrosomia 17.85%, Poor reproductive history 17.85%, baby with congenital malformation 8.33%, H/o unexplained IUFD 11.90%. H/o polyhydramnios 15.47%. History of PCOS 13.09% and preeclampsia was found in 17.85% of cases. In antenatal complications; miscarriages was found in 15.47%. polyhydramnios in 17.85%. Oligohydramnios in 8.33%, preterm labor in 11.90%, PROM in 9.52%, pre-eclampsia in 17.85%, sudden IUFD in 8.33% and congenital malformation was found in 4.76% of cases. On USG; IUGR was found in 7.14% of cases. Large for date fetus in 16.66% of cases and the normal growth was found in 76.19% of cases.Conclusions- In conclusion appropriate and timely diagnosis and treatment of GDM will result in decreased maternal and neonatal adverse outcomes comparable to general population rates, therefore, early diagnosis is important.

Modern socio-economic conditions require a new approach to the study of settlement systems. Historical and genetic analysis is one of the most effective methods used in urban planning and allows to represent rural settlement system as a set of formed elements with their own borders (historical, natural, etc.). The main stages of historical and genetic analysis include research object selection, initial data collection; analyzing the dynamics of quantitative and qualitative indicators; cartographic modeling; characterizing the settlement system interrelations; general assessment of settlement system changes. The manuscript contains research results in studying the formation features of rural settlement system in terms of Mogilev region (Republic of Belarus). The history of forming the modern rural settlement system in Belarus includes three periods: pre-revolutionary, Soviet and modern, when the most active transformation of rural settlement system took place. For each period, a retrospective analysis of the administrative-territorial division, spatial-territorial organization, and typology of rural localities is conducted. As a research result, the model of the reorganization of Belarus administrative-territorial system in the XX – early XXI centuries and the historical and genetic model of rural localities typology in Belarus are obtained. The Soviet period contributed to urbanization, rural population reduction and rural settlements reduction. The modern period is characterized by rural settlement stabilization.

Subject. We consider economic relations and problems within the framework of spatial development of settlements and constituent entities of the Russian Federation. Objectives. We focus on the development of a methodology for assessing the spacial spillover effects of investments in transport infrastructure and their monetization, considering the network and spillover effects, socio-economic characteristics, geographical location, and the level of connectivity of territories. Methods. The study employs methods of economic, statistical analysis and synthesis, and comparison. The works of economists on the problems of transport accessibility, spatial development and the impact of transport infrastructure on the dynamics of economic growth serve as the theoretical basis of the study. Results. We tested the proposed methodological toolkit, presented the results of assessing the spillover effects of investments in transport infrastructure based on the materials of the Central Federal District according to data for 2020. We determined the secondary effects of infrastructure investments, assessed the size of ‘exports’, ‘imports’ and the real size of investments in transport infrastructure, considering the secondary effects for the subjects of the Central Federal District. Conclusions. The numerical estimates of the spillover effects of investments in transport infrastructure for the subjects of the Central Federal District obtained in the work can be used in practice, when planning the development of territories and assessing the socio-economic effects of regional and interregional transport projects.

The article is the first part of the study, which examines the issues related to the study of the history of population and historical demography of Kyrgyzstan. The emphasis is made on the issues of historiography on the basis of scientific literature on the problems of history and demography of Kyrgyzstan in the 20th — 21st centuries. The analysis and assessment of the main demographic indicators of the population of Kyrgyzstan in the Soviet and post-Soviet periods is considered, the process of change in demographic policy, as well as its impact on the socio-economic situation in the republic, are analyzed. It is concluded that the historiography of the historical demography of Kyrgyzstan is based on macro approaches to the study of demography processes, which was typical for Soviet historical science as a whole. The main problems of studying the history of the population of Kyrgyzstan, to which researchers were addressed, were the population census, changes in the number and distribution of the Kyrgyz, the impact of the 1916 uprising. on the demographic development of the Kyrgyz people, the settlement of nomads on the land, socio-cultural changes in Kyrgyzstan and their impact on the change of demographic characteristics. Much attention was also paid to public policy in the field of governance and influence on demographic processes.

Improving irrigation efficiency (IE) is an approach used globally to help meet competing demands for water and facilitate reallocation of water between sectors. In the Murray–Darling Basin in Australia, the Australian government has invested heavily in IE projects to recover water for the environment. However, this approach has been seriously questioned, out of concerns that improved IE would reduce irrigation return flows to rivers and therefore offset water recovery. In this study, we use a water balance model to assess the impact of the IE projects on return flows and highlight sensitivities and uncertainties. The model enables the impact on return flows to be assessed on specific IE projects and regional characteristics. Overall, reductions in return flows are estimated to be less than 20% of the total proposed IE savings. The history of IE in the southern MDB has meant that most of the current reductions are in ground return flows. Our estimate is much lower than two previous studies, mainly due to different assumptions being used on groundwater connectivity between irrigation areas and major streams. While the IE projects significantly reduce seepage to groundwater (with off-farm and on-farm projects reducing seepage by 19% and 53% of total savings respectively), not all seepage reductions will translate to a reduction in ground return flows to rivers. A lower estimate is consistent with existing monitoring and groundwater modeling studies. In this paper, the study results are discussed in a broader context of impacts of IE projects on volumes and salinity of streams and groundwater resources.

Introduction. The sustainability of the rural settlement is a key land use planning objective in the present-day socio-economic environment. This issue is particularly relevant Belarus as the most urbanized country of the European region. The retrospective analysis is the most effective tool for studying the transformational processes underway in the settlement system. The mission of this article is to study the transformation of the rural settlement pattern in Belarus. Materials and methods. The research methodology encompasses general scientific methods (a system approach, a retrospective analysis) and special transdisciplinary methods (cartographic modeling backed by GIS tools). Population census data, open-access cartographic sources and land-use planning documents were studied, as well. Results. Three periods were identified in the history of rural settlement in Belarus: pre-revolutionary (1897–1917), Soviet (1917–1991) and contemporary ones (1991–present). Within these periods, transformational processes were particularly active. A retrospective analysis of the structure and spatial organization of rural settlement processes was performed for each period. Special features of the Belarus rural settlement structure were highlighted. They include polarization, growing population shares and sizes of major rural populated areas, the “drain” of large and medium-sized populated areas, and the degradation of small ones. Conclusions. The retrospective analysis enabled the author to identify the most significant historical periods in the history of rural settlement. Any settlement transformation was mainly driven by social and political factors. By summarizing the findings, the author identified two patterns of transformation applicable to rural settlement patterns: development and degradation. Three types of spatial reorganization of rural populated areas were formulated: relocation to the city, relocation to rural populated areas, or settlement system centres, and relocation to ordinary rural populated areas. Further research undertakings will focus on conceptualizing the spatial organization model of the rural settlement system.
