Compliance and approach to voluntary HIV testing in a high-risk region for HIV transmission in Europe

Background: The Kosovo province is being considered as a high-risk region for the spread of HIV. Objective: To estimate the prevalence and factors associated with HIV testing in a sample of university students from the Serbian northern Kosovo province. Material and Methods: A questionnaire examining socio-demographic characteristics, HIV–related knowledge, attitudes towards people living with HIV (PLHIV) and HIV testing was used in data collection. A total of 1,017 students from the University of Priština temporarily seated in Kosovska Mitrovica completed the questionnaire. Results: Only 5.4% of students have previously been tested for HIV, even though the majority (70.9%) had a positive approach to HIV testing. Factors associated with having been tested for HIV were being male and younger, having interest in HIV testing and having previous contact with PLHIV. Being more knowledgeable about HIV and having stronger positive attitude towards PLHIV, being older, receiving information about HIV through friends and special educational programs, using condom at last sexual intercourse, having positive opinion on gays/lesbians and previous contact with PLHIV were associated with positive approach to HIV testing. Conclusion: Having a positive approach to HIV testing does not suggest that students would take the HIV test. However, students who have low HIV-related knowledge, negative approach or lack of interest in HIV testing (believing that there is no need to take it) would likely never take the HIV test. Increasing HIV-related knowledge, acceptance of PLHIV and access to testing facilities should be public health priorities to raise HIV testing rates.

Synthesis and crystal structure of 1,2,3,4-tetrahydro-9-aminoacridine tetrachlorozincate(II) monohydrate

In the reaction of ZnCl(2) with tacrine hydrochloride in water novel tetracoordinated (C(13)H(15)N(2))(2)[ZnCl(4)]-H(2)O complex was obtained and characterized by elemental analysis, molar conductivity and X-ray analysis. The complex crystallizes in the space group P-1 of the triclinic crystal system. The structure contains two crystallographically different molecules of protonated tacrine present as counter cations, the [ZnCl(4)](2-) complex anion and one water solvent molecule. The counter cations slightly differ in the puckering of the cyclohexene ring. The molecules of protonated tacrine are involved in different intermolecular hydrogen bonds. In the crystal, the hydrogen bonding generates a 3D assembly. In the crystal, pi center dot center dot center dot pi stacking interactions between the rings of protonated tacrine were evidenced. The [ZnCl(4)](2-) complex anion has a distorted tetrahedral geometry. Three out of the four Cl atoms are involved in intermolecular hydrogen bonding. The intermolecular H-bond interactions involving the Cl atoms affect the Zn-CI bond lengths

Risk Perception About HIV Among University Students in One of the Last Hotspots for HIV Transmission in Europe

Abstract Background HIV testing in the Northern Kosovo province is challenging, because the infrastructure is being rebuilt after the ethnic conflict. The purpose of this research was to examine self-perceived risk for acquiring HIV infection and factors associated with risk assessment among university students. Methods Students completed a questionnaire on socio-demographic data, knowledge about HIV prevention and transmission, attitudes toward people living with (PLHIV) and self-perceived risk for HIV infection. The self-perceived risk was categorized as low, unknown and high. Results The majority of students (72.5%) assessed their risk as low, 8.5% assessed their risk as high and 19.1% did not know their risk. Compared to low self-perceived risk, high self-perceived HIV risk was associated with being male, having lower knowledge about HIV prevention, less strong Segregation and protection attitude toward PLHIV, stronger Ignorance and indifference attitude toward PLHIV and positive opinion about gays/lesbians. Students who perceived own risk for acquiring HIV as high had lower knowledge about HIV transmission and prevention. However, those who were previously tested for HIV, despite their poorer knowledge about HIV prevention, assess their HIV-related risk as low. Conclusions Students assessed their risk of HIV infection mostly as low. Still, lower knowledge of HIV prevention has been consistently associated with a high and unknown risk of HIV. Moreover, being ignorant and indifferent about PLHIV was associated with increased self-perceived HIV risk. These findings highlight the need for continuous specialized HIV-related education to reduce fear and stigma of PLHIV and HIV testing as well as risky behaviors

Synthesis, Characterization, Catalytic Activity, and DFT Calculations of Zn(II) Hydrazone Complexes

Two new Zn(II) complexes with tridentate hydrazone-based ligands (condensation products of 2-acetylthiazole) were synthesized and characterized by infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy and single crystal X-ray diffraction methods. The complexes 1, 2 and recently synthesized [ZnL3(NCS)2] (L3 = (E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-aminium) complex 3 were tested as potential catalysts for the ketone-amine-alkyne (KA2) coupling reaction. The gas-phase geometry optimization of newly synthesized and characterized Zn(II) complexes has been computed at the density functional theory (DFT)/B3LYP/6–31G level of theory, while the highest occupied molecular orbital and lowest unoccupied molecular orbital (HOMO and LUMO) energies were calculated within the time-dependent density functional theory (TD-DFT) at B3LYP/6-31G and B3LYP/6-311G(d,p) levels of theory. From the energies of frontier molecular orbitals (HOMO–LUMO), the reactivity descriptors, such as chemical potential (µ), hardness (η), softness (S), electronegativity (χ) and electrophilicity index (ω) have been calculated. The energetic behavior of the investigated compounds (1 and 2) has been examined in gas phase and solvent media using the polarizable continuum model. For comparison reasons, the same calculations have been performed for recently synthesized [ZnL3(NCS)2] complex 3. DFT results show that compound 1 has the smaller frontier orbital gap so, it is more polarizable and is associated with a higher chemical reactivity, low kinetic stability and is termed as soft molecule. © 2020 by the authors.

Immunosuppressive regimens following kidney transplantation in five European countries: The observational RECORD study

Objective: To examine current immunosuppressive regimens administered to kidney transplant recipients (KTRs) in South-eastern Europe. Methods: This was a 12-month, multicenter, non- interventional, prospective, observational study of immunosuppressive regimens in adult de novo and maintenance KTRs. The primary endpoint was to identify the number, type, dosage and trough concentrations (C0) of immunosuppressive medications. Results: Data were available for 1774 KTRs from five countries (Bulgaria [n = 109], Croatia [n = 339], Romania [n = 647], Serbia [n = 434] and Slovenia [n = 245]). The most common immunosuppressive regimen in all countries was a triple therapy regimen (de novo KTRs, 67.9 – 100% at baseline and 67.3 – 100% at end of study ; maintenance KTRs, 48.8 – 90.7% and 43.2 – 90.1%, respectively). The most frequent regimen in de novo KTRs comprised tacrolimus, mycophenolate mofetil (MMF) or mycophenolate sodium (MPS), and corticosteroids. In maintenance KTRs, the most frequent regimen was tacrolimus or cyclosporine, and MMF or MPS, with or without corticosteroids. A C0 of <5 ng/mL was recorded in 40.2% of immediate-release and 48.7% of prolonged-release tacrolimus patients ; 79.5% of patients taking cyclosporine had a C0 of <75 ng/mL. Infections were the most common adverse event (358/597, 60.0%), mainly urinary tract infections (208/358, 58.1%). Conclusions: Triple therapy—comprising a calcineurin inhibitor (CNI ; tacrolimus or cyclosporine), antiproliferative drugs (MMF or MPS) and corticosteroids—was the most common immunosuppressive regimen used in KTRs in South- eastern Europe. Individual CNI C0 were below the target range in a substantial proportion of KTRs, highlighting the need to maintain therapeutic drug monitoring of immunosuppressive therapy in this patient population
