BackgroundPrenatal drug use may cause toxicity to bone health in newborns. We aimed to examine whether birth outcomes mediate the association between medication use and neonatal metabolic bone disease (MBD).MethodsA prospective cohort of 10,801 pregnant women (17–49 years) and their infants followed at a single center from 1 January 2012 to 31 December 2021 were included. Based on four single drugs, comprehensive medication use was determined and categorized into three groups using latent-class analysis: group 1 included antibiotics and furosemide or less than two drugs except for MgSO4; group 2 included MgSO4 without antibiotics or furosemide; and group 3 encompassed dexamethasone and antibiotics. Mediation analysis was conducted to assess the mediating effects of prematurity, low birth weight (LBW), and small for gestational age (SGA).ResultsThere were 138 (1.3%) infants with MBD; 2,701 (25%) were born preterm, 1717 (15.9%) had LBW, and 303 (2.8%) were SGA. Pregnant women in groups 2 and 3 were 2.52 to 14.66 times more likely to deliver an infant with MBD than those in group 1. Only LBW showed a significant mediating effect on the association between comprehensive medication use and MBD, with a mediation proportion of 51.8% (45.0–64.1%, p &lt; 0.001).ConclusionComprehensive medication use during pregnancy was associated with an increased risk of neonatal MBD, largely mediated by LBW. Early antepartum monitoring and prevention targeting adverse birth outcomes are necessary to mitigate the risk of MBD.

Published: September 2024

We synthesized four new copper(II) complexes with acetato and chlorido ligands and methylammonium (MA), dimethylammonium (DMA), and tetramethylammonium (TMA) counterions: (MA)4[Cu2Ac4Cl2]Cl2·2H2O (1), (DMA)2[Cu2Ac4Cl2] (2), (DMA)4[Cu2Ac4Cl2]Cl2·2H2O (3), and (TMA)5[Cu2Ac4Cl]Cl4·4H2O (4). All compounds were characterized by single-crystal X-ray diffraction, magnetic measurements, FTIR spectroscopy, and thermogravimetric analysis. Complexes 1, 2, and 3 consist of a dinuclear coordination anion [Cu2(Ac)4Cl2]2− with bridging acetato ligands arranged in a paddle-wheel conformation and square-pyramidal coordination around Cu(II) atoms, while the coordination anion in compound 4 is a polymeric chain, parallel to the c axis, with Cu2(Ac)4 units connected through bridging chlorido ligands. Magnetic measurements carried out between 2 K and 300 K indicate strong antiferromagnetic interactions between Cu(II) ions. The effective magnetic moments range from 1.94 μB to 2.21 μB, exceeding the spin-only value for Cu(II) ions (μeff=1.73 μB) and suggesting significant orbital contributions to the magnetic moment. Thermogravimetric analysis of all complexes showed a multistep decomposition behavior yielding elemental copper as the final product.

Published: September 2024

Thelyphonida Blanchard, 1852, also known as vinegaroons or whip-scorpions, is a small arachnid order with 140 described species contained in a single family, Thelyphonidae Lucas, 1835. Despite being conspicuous and widely distributed across the tropics and subtropics on four continents, knowledge of the order has been slow to advance. Hypoctoninae Pocock, 1899, one of four subfamilies currently recognized and one of two represented in the New World, comprises five genera. Since its inception, Thelyphonellus Pocock, 1894 has remained the only hypoctonine genus occurring in South America, with only four species described prior to the present contribution. The first detailed morphological study and phylogenetic analysis of Thelyphonellus is presented herein. The morphological phylogenetic analysis—the first for Thelyphonida—includes all except one of the previously described species of Thelyphonellus in addition to two new species described herein; the species of Ravilops Víquez and Armas, 2005 (from the Caribbean island of Hispaniola); and the monotypic Old World genus Etienneus Heurtault, 1984 (from West Africa) scored for 45 morphological characters. A single, most parsimonious phylogenetic hypothesis revealed that Thelyphonellus is paraphyletic with respect to Ravilops. The New World Hypoctoninae comprises four clades with disjunct distributions and well supported by a combination of morphological characteristics, on the basis of which four genera, two of which are new, are recognized: Ravilops, with two species, endemic to Hispaniola; Thelyphonellus, herein restricted to Thelyphonellus amazonicus (Butler, 1872) and Thelyphonellus ruschii Weygoldt, 1979, occurring in Guyana, Suriname, French Guiana, and northern Brazil; Wounaan, gen. n., containing Wounaan vanegasae (Giupponi and Vasconcelos, 2008), comb. n. and Wounaan yarigui, sp. n. from Colombia; and Yekuana, gen. n., containing Yekuana venezolensis (Haupt, 2009), comb. n. and Yekuana wanadi, sp. n. from Venezuela. The two new species are described and illustrated. A key to the identification of the Neotropical genera of Hypoctoninae and a map plotting the known distribution of its species are also presented.

In the context of the “ecological priority and green development” strategy, examining the co-evolution between the tourism economy and the efficiency of urban green development can offer both theoretical insights and quantitative foundations to support ecological preservation and high-quality development in China’s Yellow River Basin. This research utilized approaches such as the Haken model and the geographically and temporally weighted regression model to investigate the spatiotemporal patterns, synergistic characteristics, and driving factors of the tourism economy and urban green development efficiency within the Yellow River Basin. The findings reveal the following: (1) Regional disparities in the tourism economy are progressively widening, whereas the efficiency of green development tends to decline. Furthermore, both the tourism economy and urban green development efficiency display “high-high clustering” and “low-low clustering” spatially. (2) The synergistic evolution of the two systems displays spatial characteristics of transitioning from polarization to trickle-down effects. (3) Natural factors such as topography and vegetation coverage, as well as human economic factors like industrial structure and the degree of openness, positively promote the synergy. However, elements such as temperature, precipitation, economic development level, and openness to innovation have a certain inhibitory effect on the synergistic evolution.

Отмечена высокая заинтересованность населения, государства и стран в решении важной проблемы цифрового разрыва посредством обеспечения равного доступа к информации в сфере здравоохранения. Представлены результаты анализа экономической эффективности при внедрении телемедицинских проектов в учреждениях здравоохранения. Использованы два подхода к оценке – «затраты-выгоды» и «затраты-полезность», – что позволяет определить изменения не только издержек, но и продолжительности жизни людей.
The article proposes a variant of decentralization of the telemedicine network, which provides for the possibility of providing first-priority set of telemedicine services in networks with ultra-low delays. The high interest of the population, the state and countries to solve an important problem of the digital divide through ensuring equal access to information in the field of healthcare is noted. The results of the analysis of economic efficiency in the implementation of research projects in health care in the collection of domestic and foreign works are shown. Two definitions of evaluation are used - “cost-benefit” and “cost-utility”, which allow to determine not only the increase/decrease in costs, but also the increase in life expectancy.
Spatial patterns of electoral support in the 2023 general election in Poland
Authors: Kavetskyy Igor , Kavetska Tatiana 
Published: September 2024

RESEARCH OBJECTIVE: This article focuses on identifying the spatial patterns of electoral support for the main political actors, and searching for adequate determinants that explain this distribution of support, based on the results of the 2023 general election in Poland.
THE RESEARCH PROBLEM AND METHODS: Is there a relationship between the basic morphological features of the voting space in Poland and the hierarchy of the settlement structure, along with the arrangement of regions associated with the country’s historical and political heritage? The methods used in the study include analysis of descriptive statistics, estimation of spatial autocorrelation, discriminant analysis, and cartographic methods.
PROCESS OF ARGUMENTATION: The research process involves a two-stage procedure: 1) identifying a general picture of spatial variation in electoral support for selected groupings, and basic clustering patterns of electoral support; and 2) estimating links between the observed patterns of support and their presumed determinants; that is, the country’s settlement hierarchy and historical-political divisions.
RESEARCH RESULTS: The spatial variability of the support indicators is characterised by a distinctive territorial distribution, based on the units of the settlement system and the boundaries of former historical divisions. The nature of this linkage indicates the changing layout of the voting space, associated with the increasing polarisation of citizens’ political preferences.
CONCLUSIONS, INNOVATIONS, AND RECOMMENDATIONS: The current pattern of urban-rural differentiation is related to the different preferences of metropolitan (over 20,000 inhabitants) and rural or small-town (up to 20,000 inhabitants) communities. The east-west heterogeneity of Poland’s voting space is increasing due to similarities of preferences among the inhabitants of former Austrian and Russian Poland, on the one hand, and Prussian Poland and the Recovered Territories, on the other.
Obraz zaangażowania politycznego kobiet w Polsce w III RP w świetle badań World Values Survey
Authors: Bałandynowicz-Panfil Katarzyna 
Published: September 2024

CEL NAUKOWY: Celem opracowania jest ukazanie wpływu czasu oraz zmian społeczno-ekonomicznych na postawy Polek wobec polityki i polityków.
PROBLEM I METODY BADAWCZE: Opierając się na danych z World Values Survey (1990–2022), przeanalizowano zmianę postaw kobiet w Polsce wobec polityki i partycypacji jednostki w szeroko pojętym życiu politycznym. Analiza statystyczna danych wtórnych stanowi bazę dla badań porównawczych w czasie.
PROCES WYWODU: Punktem wyjścia rozważań jest specyfika kultury narodowej w Polsce. Zachodzące przemiany o charakterze społecznym i ekonomicznym silnie oddziałują na zachowania jednostek. Rosnąca świadomość w odniesieniu do polityki oraz chęć partycypacji w życiu politycznym to przejaw zachodzących zmian w kierunku demokratyzacji społeczeństwa. Łączy się to silnie z emancypacją kobiet i ich rosnącą aktywnością społeczną i polityczną. Jednocześnie Polska jest krajem o silnie ugruntowanych wartościach tradycyjnych, które nie motywują kobiet do zaangażowania politycznego.
WYNIKI ANALIZY NAUKOWEJ: Polki nie są znacząco zainteresowane tematami politycznymi i nie ukrywają stosunkowo niskiej świadomości w zakresie własnych postaw i orientacji politycznej, jak również braku umiejętności określenia stopnia zaufania do instytucji politycznych w kraju. Aktywność polityczna kobiet sprowadza się głównie do podpisywania petycji i udziału w wyborach.
WNIOSKI, INNOWACJE, REKOMENDACJE: Deklarowane wśród kobiet niskie zainteresowanie tematami politycznymi wskazuje na utrzymujący się podział w społeczeństwie na męskie i żeńskie obszary życia społecznego. Jest to zgodne z obserwowanym silnym przywiązaniem Polaków do wartości tradycyjnych. Podejście w ujęciu czasowym daje znacznie szerszy obraz w zakresie społecznych wartości i ich wpływu na postrzeganie i chęć uczestniczenia w życiu politycznym. Dodatkowo zestawienie obserwacji opartych na cechach specyficznych dla danej kultury narodowej stanowi istotne uzupełnienie dotychczasowych rozważań w literaturze przedmiotu. Wnioski prowadzą do rekomendacji o charakterze naukowym (badań interdyscyplinarnych na rzecz lepszego zrozumienia mechanizmów kształtujących postawy wobec polityki i polityków) oraz praktycznym (budowania scenariuszy bardziej efektywnych działań na rzecz partycypacji politycznej społeczeństwa).
