Published: September 2019

OBJECTIVE
Type 1 diabetes is associated with a higher risk of cardiovascular disease (CVD) in women. Although menopause increases risk of CVD, it is uncertain how menopause affects risk of CVD in women with type 1 diabetes. We examined whether risk of CVD changes differentially in women with and those without type 1 diabetes over the transition through menopause.

RESEARCH DESIGN AND METHODS
Premenopausal women with type 1 diabetes (n = 311) and premenopausal women without diabetes (n = 325) enrolled in the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study and attended up to four study visits over 18 years. Coronary artery calcium (CAC) volume was measured from computed tomography scans obtained at each visit. Longitudinal repeated-measures modeling estimated the effect of diabetes on CAC volume over time and the effect of menopause on the diabetes-CAC relationship.

RESULTS
CAC volume was higher at baseline and increased more over time in women with type 1 diabetes than in women without diabetes. A significant diabetes-by-menopause interaction was found (P &lt; 0.0001): postmenopausal women with type 1 diabetes had significantly higher CAC volumes than premenopausal women (5.14 ± 0.30 vs. 2.91 ± 0.18 mm3), while there was no difference in women without diabetes (1.78 ± 0.26 vs. 1.78 ± 0.17 mm3). This interaction remained significant after adjusting for CVD risk factors.

CONCLUSIONS
Type 1 diabetes was associated with higher CAC volume and accelerated progression of CAC over time. Menopause increased CAC progression more in women with diabetes than in women without diabetes independent of age and other CVD risk factors known to worsen with menopause.

Abstract

Objective: Our study aimed to validate the neutrophil-to-lymphocyte ratio (NLR) as a marker for aortic arch calcification in hypertensive patients with less advanced chronic kidney disease (CKD).

Methods: A number of forty-four hypertensive patients with chronic kidney disease (categories G3a and G3b – 2012 KDIGO nomenclature) were included in the study. Considering the presence of aortic arch calcification (AAC) on chest X-ray, the study population was divided into two groups: 27 patients AAC present and seventeen without aortic arch calcification. Laboratory data were collected for each patient and NLR was computed. Comorbidities were also recorded: stable coronary artery disease, lower extremity arterial disease and hypertensive heart disease.

Results: A positive correlation between neutrophil-to-lymphocyte ratio and aortic arch calcification in hypertensive CKD patients was identified. Furthermore, advanced age, increased alkaline phosphatase and increased erythrocyte sedimentation rate had a positive association with aortic arch calcification. We found no statistical correlation between neutrophil-to-lymphocyte ratio and other laboratory features in both groups of patients.

Conclusions: Neutrophil-to-lymphocyte ratio may be viewed as a potential risk factor for vascular calcification in patients with moderate chronic kidney disease; nevertheless, future extensive studies are necessary. In the management of hypertensive patients, general medicine might particularly benefit of this simple, readily available inflammatory marker.

Abstract

Objective: The study aims to analyze obesogenic behavioral patterns of adolescents living in Mureş County, Romania, as well as to establish a relationship between these behaviors and their Body Mass Index (BMI), in an attempt to provide effective prevention strategies for obesity.

Material and Methods: 153 students between 9th to 12th grade, aged between 14 and 19 years old, from the Vocational and Art Highschool of Târgu Mureş were included in the study. All the candidates filled out an evaluation questionnaire of lifestyle and risky behaviors. The analyzed data were sex, age, residence, BMI and risky eating behavior defined as the consumption of carbohydrates (bread, potatoes, sweets), sodas, junk food, alcohol (wine, distilled beverages, beer), beer separately, level of physical activity (school and extra-school sports activities), sedentary behaviors (≥2 hours/day in front of a screen: personal computer-PC and television-TV), and spending ≥2 hours/day separately on the PC and on the TV.

Results: A statistically significant association was observed between BMI and consumption of fast-food, tobacco, beer, sedentary behavior and spending ≥2 hours/day in front of the PC. Moreover, there was a statistically significant difference between the BMI values of adolescents presenting all studied risk behaviors compared to those who did not.

Conclusions: Obesity among adolescents from Mureş County is influenced by lifestyle choices like fast-food, tobacco, beer, sedentary behavior and spending ≥2 hours/day in front of the PC.

Abstract

Parquetina nigrescens leaves have been used in traditional medicine as an important and highly efficacious herbal remedy and have been recommended as a potential source of antimicrobial agent. Three extracts of the plant obtained using n-hexane, methanol and water were used as solvents. Phytochemical analysis of the plant extracts showed important bioactive compounds such as flavonoids, saponins, tannins, terpenes, steroids, phenols and glycosides, but alkaloids were absent in all the three extracts. Agar disk diffusion method was used to study the antimicrobial activity of the extracts at different concentrations which showed activity against three gram negative bacteria Escherichia coli, Klebsiella pneumoniae and Proteus spp., one gram positive bacteria Staphylococcus aureus, and two fungus Aspergillus flavus and Candida albicans with zone of inhibition ranging from 5-15 mm for n-hexane extract, 6-16 mm for methanol extract and 1-11 mm for aqueous extract compared to zone of inhibition for the standard antibacterial drug, 0.5 mg/mL Streptomycin that ranges from 13 – 37 mm and the zone of inhibition for the standard antifungal drug 5 mg/mL fluconazole that ranges from 24 – 25 mm. Klebsiella pneumoniae was the most inhibited while E. coli was the least inhibited by the extract, and Candida albicans was found to be resistant to the extracts in all the concentrations. TLC finger-printing of the extracts using the solvent system – butanol : acetic acid : ethanol : distilled water in the ratio 50:10:10:30 showed spots with peaks different retention times ranging from 0.24 - 0.74 cm. The results provide justification for the use of the plants in folk medicine to treat various infectious diseases.
Course Sequence Recommendation with Course Difficulty Index Using Subset Sum Approximation Algorithms
Authors: Premalatha M. , Viswanathan V. 
Published: September 2019

Abstract
Choice Based Course Selection (CBCS) allows students to select courses based on their preferred sequence. This preference in selection is normally bounded by constraints set by a university like pre-requisite(s), minimum and maximum number of credits registered per semester. Unplanned course sequence selection affects the performance of the students and may prolong the time to complete the degree. Course Difficulty Index (DI) also contributes to the decline in the performance of the students. To overcome these difficulties, we propose a new Subset Sum Approximation Problem (SSAP) aims to distribute courses to each semester with approximately equal difficulty level using Maximum Prerequisite Weightage (MPW) Algorithm, Difficulty Approximation (DA) algorithm and Adaptive Genetic Algorithm (AGA). The three algorithms have been tested using our university academic dataset and DA algorithm outperforms with 98% accuracy than the MPW and AGA algorithm during course distribution.
Team Learning Processes and Activities in Organization: A Case Study
Authors: Lazarević Snežana , Lukić Jelena 
Published: September 2019

Abstract
Organizations in today’s environment are relied on teams and their learning as key determinants for survival and success. The aim of this paper is to identify the key team learning processes and activities in organizations and to examine how the eventual appearance and growth of the problems in team impact on those processes and activities. Research was conducted in nine teams with 79 members in one public service organization located in Belgrade, Serbia, using interview and questionnaire techniques. Descriptive analysis, linear regression and Pearson correlation coefficient were used for processing and interpreting collected data. The results show that undefined roles of team members, a lack of trust among them, inadequate rewards, inadequate leadership and team management, will cause a moderate decrease in team learning processes and activities. The value of this research is that growing reliance on teamwork in organizations put pressure on leaders and managers to understand the factors that enable and stimulate team learning processes and activities, but also to identify and overcome all problems that may arise in teams and slow down the learning in teams as one of the most important processes.
Cu(II), Co(II), Ni(II), Mn(II) and Zn(II) Schiff base complexes of 3-hydroxy-4-[N-(2-hydroxynaphthylidene)-amino]-naphthalene-1-sulfonic acid: Synthesis, Spectroscopic, thermal, and antimicrobial studies
Authors: Bakare Safyah B. 
Published: September 2019

Abstract
Five divalent transition metals Cu(II), Co(II), Ni(II), Mn(II) and Zn(II) complexes have been synthesized using 3-hydroxy-4-[N-(2-hydroxynaphthylidene)-amino]-naphthalene-1-sulfonic acid (H3L) Schiff base as a ligand derived from the condensation reaction between 4-amino-3-hydroxynaphthalene-1-sulfonic acid and 2-hydroxy-1-naphthalde-hyde. The synthesized complexes were characterized using microanalytical, conductivity, FTIR, electronic, magnetic, ESR, thermal, and SEM studies. The microanalytical values revealed that the metal-to-ligand stoichiometry is 1:1 with molecular formula [M2+(NaL)(H2O)x].nH2O (where x = 3 for all metal ions except of Zn(II) equal x = 1; n = 4, 10, 7, 4, and 6 for Cu(II), Co(II), Ni(II), Mn(II) and Zn(II), respectively). The molar conductivity result indicates that all these complexes are neutral in nature with non-electrolytic behavior. Dependently on the magnetic, electronic, and ESR spectral data, octahedral geometry is proposed for all the complexes except to zinc(II) complex is tetrahedral. Thermal assignments of the synthesized complexes indicates the coordinated and lattice water molecules are present in the complexes. SEM micrographs of the synthesized complexes have a different surface morphologies. The antimicrobial activity data show that metal complexes are more potent than the parent ligand.

Published: September 2019

Abstract
Pericarps of Algerian Quercus ilex (Q. ilex) and Quercus suber (Q. suber) were used as copper adsorbents in artificially contaminated solutions. Exposing accessible lignocellulosic binding sites enhanced adsorption. The lignocellulosic fractions of Q. suber and Q. ilex (36.47±9.1 and 47.66±9.3, respectively) were characterized by FTIR before and after adsorption. The aim was to identify the functional groups adsorbing Cu(II). SEM/EDX determined lignocellulose surface morphology and composition. The amount of adsorbent-bound Cu(II) increased with initial [Cu(II)]. Cu(II) adsorption range was 23.59–48.06 mg.g−1 for Q. Suber and 22.56–38.19 mg.g−1 for Q. ilex when [Cu(II)] was 100–500 mg.L−1. Adsorption isotherms and Langmuir and Freundlich models of the Q. suber and Q. ilex lignocellulosic fractions indicated natural Cu(II)adsorption capacities (Qmax) of 53.76 mg.g−1 and 36.06 mg.g−1 and KF of 5.9 mg.g−1 and 7.43 mg.g−1, respectively.

Published: September 2019

Aim: The aim of this study was to analyse the relationship between medical students’ level of information literacy and the development level of their strategies to search information online according to various variables, and thus to determine the possible relation between them. Methods: The research design of this study was survey model. The working group of the study was composed of medical students who were at their first, second and third year at Hacettepe University, Faculty of Medicine during the academic year of 2017-2018. The data of the study were collected from 462 volunteer students electronically. The data were gathered by means of using “Personal Information Form,” “Online Information Search Strategies Inventory,” “Scale of Information Literacy” and “Students’ Opinions Form.” The quantitative data of the study were analysed with SPSS 22. The qualitative data were analysed according to the themes and sub-themes that had been prepared by the researchers.Results and Conclusion: It was found that students’ self-efficacy perception level about information literacy and the development level of their strategies to search information online were both medium, and that there was a positive relation between them at a medium level. On the other hand, students that were studying at the first year and with have high grade were found to have significantly higher levels of information literacy and online search strategies development than the students studying at the other two years. This difference is thought to result from the fact that during the academic year when the study was carried out, students studying at the first year received a sub-module of ‘Information Literacy’ within the framework of the programme called ‘Faculty of Medicine – I am Learning to be a Physician.’ The qualitative data show that students decide on keywords before they start to do research online, choose a suitable database, evaluate the conformity of the gathered information with their own goal, resort to peer support and make a comparison with their foreknowledge
