Dicarbonyl­dichlorido(N,N,N′,N′-tetra­methyl­ethylenediamine)­ruthenium(II)

In the title compound, [RuCl2(C6H16N2)(CO)2], the geometry around the RuII atom is a distorted RuC2N2Cl2 octa­hedron, with pairs of C and Cl atoms trans to each other and the N atoms of the bidentate ligand in a cis conformation. The five-membered chelate ring is puckered on the C—C bond

Metal Complexes of Multidentate N2S2 Heterocyclic Schiff-base Ligands;Formation, Structural Characterisation and Biological Activity

The synthesis of ligands with N2S2 donor sets that include imine, an amide, thioether, thiolate moieties and their metal complexes were achieved. The new Schiff-base ligands; N-(2-((2,4-diphenyl-3-azabicyclo[3.3.1]nonan-9-ylidene)amino)ethyl)-2-((2-mercaptoethyl)thio)-acetamide (H2L1) and N-(2-((2,4-di-p-tolyl-3-azabicyclo[3.3.1]nonan-9-ylidene)amino)ethyl)-2-((2-mercaptoethyl)thio) acetamide (H2L2) were obtained from the reaction of amine precursors with 1,4-dithian-2-one in the presence of triethylamine as a base in the CHCl3 medium. Complexes of the general formula K2[M(Ln)Cl2], (where: M = Mn (II), Co(II) and Ni(II)) and [M(Ln)], (where: M = Cu(II), Zn(II) and Cd(II); n =1-2, expect [Cu(HL2)Cl]) were isolated. The entity of ligands and complexes including their purity were confirmed using elemental microanalysis (C.H.N.S), atomic absorption (A.A), chloride content, conductivity measurement's, melting point and thermal analysis technique. The molecular structures were elucidated with FT-IR, UV-Vis, magnetic susceptibility, 1H-and 13C-NMR and mass spectroscopy. The synthesised compounds were evaluated for their activity against bacterial strains (G+ and G-) and fungi species. The tested compounds indicated that; the ligands have not shown any antimicrobial activity against Escherichia coli. The Cd(II) complexes, for ligands H2L1 and H2L2, display the higher antimicrobial activity, compared with the other complexes. The H2L1 and H2L2 have not shown any activity against Candida albicans. All complexes for ligands (H2L1 and H2L2) exhibited less activity against Candida albicans, compared with other types of fungi

Pregnancy, delivery and neonatal outcomes in women with a cerebrovascular-accident history prior to delivery - Evaluation of a population database

Objective: Cerebrovascular accidents (CVA) in childbearing-age women are rare. We aimed to evaluate the association between CVA events prior to delivery and obstetrical and neonatal outcomes. Methods: A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP–NIS) database. All pregnant women who delivered or had a maternal death in the US from 2004 to 2014 were included in the study. We performed a comparison between women with an ICD-9 diagnosis of CVA before the delivery admission and those without. Obstetrical and neonatal outcomes were compared between the two groups. Results: In total, 9,096,788 women fulfilled the inclusion criteria. Among them, 695 women (7.6 per 100,000) were diagnosed with a CVA before delivery. Women with a history of CVA, compared to those without, were more likely to be Black, older than 35 years of age, and suffer from obesity, chronic hypertension, pregestational diabetes, and thyroid disease. Patients with a prior CVA, compared to those without, had higher rates of pregnancy-induced hypertension (aOR 6.41, 95% CI 5.03–8.39, p < 0.001), preeclampsia (aOR 7.65, 95% CI 6.03–9.71, p < 0.001), and eclampsia (aOR 171.56, 95% CI 124.63–236.15, p < 0.001). Additionally, they had higher rates of preterm delivery (aOR 1.72, 95% CI 1.33–2.22,p = 0.003), cesarean section (aOR 2.69, 95% CI 2.15–3.37, p < 0.001), and maternal complications such as a peripartum hysterectomy (aOR 11.62, 95% CI 5.77–23.41, p < 0.001), postpartum hemorrhage (aOR 3.39, 95 % CI 2.52–4.54, p < 0.001), disseminated intravascular coagulation (aOR 16.32, 95% CI 11.33–23.52, p < 0.001), venous thromboembolism (aOR 45.08, 95% CI 27.17–74.8, p < 0.001), and maternal death (aOR 486.11, 95% CI 307.26–769.07, p < 0.001). Regarding neonatal outcomes, patients with a prior CVA, compared to those without, had a higher rate of intrauterine fetal demise and congenital anomalies. Conclusion: Women with a CVA event before delivery have a significantly higher incidence of maternal complications, including hypertensive disorders of pregnancy, and neonatal complications, such as intrauterine fetal demise and congenital anomalies. Rates of maternal death were dramatically increased, and this association requires further evaluation
