BACKGROUND

High blood pressure is one of the most common reasons why patients seek assistance in daily clinical practice. Screening for hypertension is fundamental and, because hypertension is identified only when blood pressure is measured, accurate measurements are key to the diagnosis and management of this disease. The European Society of Hypertension International Protocol revision 2010 (ESH-IP2) was developed to assess the validity of automatic blood pressure measuring devices that are increasingly being used to replace mercury sphygmomanometers.

OBJECTIVE

We sought to determine whether the iHealth Track blood pressure monitor meets ESH-IP2 requirements for self-measurement of blood pressure and heart rate at the brachial level and is appropriate for use in the general population.

METHODS

This study was a descriptive investigation. ESH-IP2 requires a total number of 33 participants. For each measure, the difference between observer and device blood pressure and heart rate values is calculated. In all, 99 pairs of blood pressure differences are classified into 3 categories (≤5, ≤10, and ≤15 mm Hg), and 99 pairs of heart rate differences are classified into 3 categories (≤3, ≤5, and ≤8 beats/min). We followed these protocol procedures in a convenience sample of 33 participants.

RESULTS

iHealth Track fulfilled ESH-IP2 requirements and passed the validation process successfully. We observed an absolute difference within 5 mm Hg in 75 of 99 comparisons for systolic blood pressure, 78 of 99 comparisons for diastolic blood pressure, and 89 of 99 comparisons for heart rate. The mean differences between the test and standard readings were 4.19 (SD 4.48) mm Hg for systolic blood pressure, 3.74 (SD 4.55) mm Hg for diastolic blood pressure, and 1.95 (SD 3.27) beats/min for heart rate. With regard to part 2 of ESH-IP2, we observed a minimum of 2 of 3 measurements within a 5-mm Hg difference in 29 of 33 participants for systolic blood pressure and 26 of 33 for diastolic blood pressure, and a minimum of 2 of 3 measurements within a 3-beat/min difference in 30 of 33 participants for heart rate.

CONCLUSIONS

iHealth Track readings differed from the standard by less than 5, 10, and 15 mm Hg, fulfilling ESH-IP2 requirements. Consequently, this device is suitable for use in the general population.
An Ototoxicity Grading System Within a Mobile App (OtoCalc) for a Resource-Limited Setting to Guide Grading and Management of Drug-Induced Hearing Loss in Patients With Drug-Resistant Tuberculosis: Prospective, Cross-Sectional Case Series (Preprint)
Authors: Hollander Cara , Joubert Karin , Schellack Natalie
Published: March 2019

BACKGROUND

Tuberculosis (TB) affects millions of people worldwide and is treated with medication including aminoglycosides and polypeptides. Individuals respond differently to medications as a result of their genetic inheritance. These differences in genetic inheritance can result in the underdosing or overdosing of medication, which may affect the efficacy or, in the case of aminoglycosides and polypeptides used in the treatment of all forms of TB, result in ototoxicity. When ototoxicity is detected, physicians should adjust dosages to minimize further ototoxicity and hearing loss; however, there are no suitable grading systems to define significant hearing loss.

OBJECTIVE

The aim of this study was to develop a standardized grading system by making use of an electronic health (eHealth) platform to ensure that a user-friendly method was available to interpret hearing test results, calculate significant hearing loss, and provide recommendations with regard to dosage adjustments and management. It further aimed to establish the sensitivity of the newly developed grading scale.

METHODS

This grading system was developed in South Africa based on data that were obtained from an audiology and pharmacokinetic study on patients with drug-resistant TB (DR-TB) at two DR-TB units at state-run hospitals. This feasibility study employed a prospective, cross-sectional, exploratory, descriptive case series research design, with a total of 22 participants. Participants underwent audiological and pharmacological assessments at baseline and every 2 weeks for the first 3 months of treatment. Various professionals (8 in total) were subsequently involved in the development of the eHealth system, including a software engineer, four audiologists, a pharmacist, a medical doctor, and a nurse. The app underwent 14 modifications that involved aspects of data storage, ease of usability, grades, and the risk factor checklist.

RESULTS

An ototoxicity grading system within a mobile app for use by doctors, nurses, and audiologists was developed for patients with DR-TB. The purpose of this user-friendly ototoxicity calculator, OtoCalc, is to (1) assist health professionals in assessing patients for ototoxicity, (2) establish the clinical significance of ototoxicity by calculating the grade of hearing loss, (3) monitor the progression of hearing loss, and (4) enable systematic referral and management of patients according to their needs.

CONCLUSIONS

This newly developed system is more sensitive than the existing grading methods for determining ototoxicity in patients with DR-TB. This app needs to be trialed in a larger sample to establish data security, ease of use, and suitability within this population.

This paper investigated the influence of school location on students’ acquisition of knowledge-based skills in selected secondary technical schools in Cross River and Imo States of Nigeria. The objective of the study was to ascertain the influence of location (urban and rural) of secondary technical schools on students’ acquisition of knowledge-based skills (creative thinking, innovation, ICT and entrepreneurship skills) in the two states. A correlation design was adopted for the study. The population constituted 1328 SS II students drawn from 11 secondary technical schools across the two states out of which a stratified random sample of 330 was identified. Two research questions and two corresponding hypotheses were formulated to guide the study. A twelve-item multiple choice Students’ Aptitude Test on Skills Acquisition (SATSA), validated by five experts in instruments construction, and was administered on the sample for data collection. Data were analyzed with One Sample Test and ANOVA to ascertain the relationship between school locations and students’ acquisition of knowledge-based skills in the identified knowledge-based skill subjects. The paper recommended that principals and teachers of secondary technical schools should sustain and improve the performance of students in the two states. It further recommended that further investigations be conducted to ascertain students’ acquisition of knowledge-based skills irrespective of school location.

Ar-rohmah English Community is an extracurricular program which provides time and creates opportunity to learn English speaking skill. The aims of this study are to describe kinds of speaking activities used in Ar-Rohmah English Community Program in SMA Ar-Rohmah Malang, to find out the problems related to teaching and learning English speaking skill activities in AEC Program and to investigate the solutions for the problems. The use of research design in this study was descriptive qualitative in which the instrument used to get the data were observation, questionnaire and interview. It was presumed as the proper design in order to attain the purpose in overcoming and solving the research problems. This study obtained the data from twenty-four students and two English teachers who were involved in the AEC Program. After analyzing the data, it is found that English teachers use seven speaking activities in Ar-Rohmah English Community Program. Those seven activities are free speaking, card game, watching movie, interview, storytelling, science writing presentation and dialogue activities. Furthermore, the problems found related to teaching and learning English speaking skill are derived from linguistic and non-linguistic factors. From linguistic factors, it is found that the students face the difficulty on mastering vocabulary, choosing appropriate grammar, lacking of pronunciation experience and not habituated with English. Moreover, from non-linguistic factor, they are reluctant to speak in English because they are inhibited, have nothing to say, have low participation and feel ease and safe using mother tongue language. Besides, the teachers face the difficulty such as get tired to handle a large class with only two teachers, confused to choose suitable activity, do not remember students’ names, hard to motivate the students to speak in English and lack of preparation time. In addition, other activity which is Pandu Hidayatullah influences the students’ passion toward AEC Program. Dealing with those problems, the teachers keep creating creative, fun and interesting activity to improve the students’ vocabulary, grammar, pronunciation and familiarized the students with English. By creating regulations, they solve the problems of students’ low motivation to use English hard to push the students using English
Identifying factors that influence individuals’ intentions to quit body tanning: A sociocultural perspective
Authors: Yoo Jeong-Ju , Lee Seahee
Published: March 2019

Our goal was to examine the factors that influence individuals’ intentions to quit body tanning and its relationship with engaging in body-tanning behaviors. Via an online survey, 385 students answered items about their tanning motivations with respect to perceptions of attractiveness
of tanning and physical fitness, influence of media, family, and friends, and skin-aging concerns. Structural equation modeling revealed that individuals’ motivation toward perceived attractiveness of a tan negatively influenced their intention to quit tanning, and skin-aging concerns
positively influenced their intention to quit tanning. However, the influence of media, family, and friends, and perceived physical fitness were not identified as significant factors in their intention to quit tanning. The attractiveness of a tanned appearance increased the likelihood of body-tanning
behaviors, whereas skin-aging concerns decreased the likelihood of body-tanning behaviors. The findings provide important implications for skin cancer prevention strategies. Emphasizing negative appearance-related consequences of tanning would certainly be a body-tanning deterrent, especially
for young image-conscious individuals.
Disruptive behaviors in online games: Effects of moral positioning, competitive motivation, and aggression in “League of Legends”
Authors: Lee Sung Je , Jeong Eui Jun , Jeon Joon Hyun
Published: March 2019

Disruptive behaviors, such as intentional violations and verbal attacks, frequently happen in multiplayer online games. However, few studies have been conducted to empirically explore the antecedents to such disruptive behaviors or the role of moral positioning in relation to such behaviors.
With 343 players of the game League of Legends, we tested an integrated path model of the relationships among moral positioning (i.e., preference for evil roles or characters in the game), aggression, competitive motivation, and disruptive behaviors. The results showed that moral positioning
was affected by both aggression and competitive motivation. The increase of moral positioning, in turn, enhanced the degree of disruptive behavior. The theoretical and practical implications of the study results are discussed.

Authors: Liao Hung-Chang , Wang Ya-huei
Published: March 2019

We developed the Reflective Thinking Scale for Healthcare Students and Providers (RTS-HSP) in Chinese by conducting a systematic literature review and consulting with a panel of experts. Participants were 579 randomly selected healthcare students and professionals from Taiwan. Using
exploratory factor analysis we developed 22 items rated on a 9-point Likert scale, and extracted 4 factors: reflective skepticism (6 items explaining 29.48% of the variance), self-examination (6 items explaining 11.41% of the variance), empathetic reflection (5 items explaining 8.96% of the
variance), and critical open-mindedness (5 items explaining 6.81% of the variance). Cronbach’s alpha reliability values for the 4 dimensions and the overall scale ranged from .77 to .87. An assessment of the RTS-HSP’s concurrent validity with the Questionnaire for Reflective Thinking
also supported our scale’s external validity. Thus, the RTS-HSP can be considered a reliable instrument for measuring reflective thinking among healthcare students and professionals.

Published: March 2019

W artykule Autorzy nawiązują do teorii renty gruntowej ze szczególnym uwzględnieniem renty absolutnej, co do istnienia, której w ekonomii nie ma zgodności. Celem rozważań jest ocena, jak współcześnie kształtuje się renta z tytułu rzadkości ziemi rolniczej w warunkach aktualnych tendencji na rynku ziemi w Unii Europejskiej i dylematów w tym zakresie. Podjęto się przy tym weryfikacji tezy, że konieczne jest odmienne podejście do absolutnej renty z ziemi, uzależniając ją od struktury obszarowej i własnościowej czy celów produkcyjnych gospodarstw rolnych. Obserwowane prawidłowości mogą jednak ulegać zmianom w wyniku wprowadzania lub zwiększania ograniczeń obrotu nieruchomościami rolnymi unormowanych prawem europejskim lub poszczególnych państw członkowskich UE, jak i postulowanych instrumentów wspólnej polityki rolnej.
Deconsumption in consumer behaviour of Polish seniors
Authors: Zalega Tomasz
Published: March 2019

Deconsumption is manifested as voluntary abandonment of behaviours aimed at satisfying the desires created by marketers in favour of conscious, rational and ethical choices to meet one’s needs. This consumer trend essentially involves voluntary discontinuation of egocentric consumption behaviour that may result both from the motivation of an egocentric individual focused on the good and from concern for the welfare of social groups, future generations and the natural environment, or may ensue from purely altruistic motivation. The article seeks to provide some insight into the reasons and scope of deconsumption in consumer behaviour of people aged 65+ in Poland. The study consists of two parts: theoretical and empirical. The first one explains the concept and essence of deconsumption as well as its key forms and determinants, building upon a critical analysis of literature. The second, major part is empirical. The basis for conclusions is provided by research material collected by means of a questionnaire-based survey among Polish seniors. The survey clearly shows that the level of deconsumption, and thus consumer behaviour consistent with this trend, is most influenced by demographic and social characteristics of those aged 65+ such as: age, sex, education, income and place of residence. It turned out that the female seniors surveyed evinced more interest in deconsumption than their male counterparts. Following the analysis, it can also be concluded that young old people (65–74) who have completed higher and secondary education, earn a monthly income of above PLN 3000.00 per capita, live in Warsaw, Gdańsk, Wrocław and Poznań and actively participate in UTA courses are most strongly influenced by the deconsumption trend, which is becoming an increasingly common way of life for the elderly.

Published: March 2019

Even in a trace amounts, the presence of antibiotics in aqueous solution is getting more and more attention. Accordingly, appropriate technologies are needed to efficiently remove these compounds from aqueous environments. In this study, we have examined the electrochemical oxidation (EO) of sulfamethoxazole (SMX) on a Co modified PbO2 electrode. The process of EO of SMX in aqueous solution followed the pseudo-first-order kinetics, and the removal efficiency of SMX reached the maximum value of 95.1 % within 60 min. The effects of major factors on SMX oxidation kinetics were studied in detail by single-factor experiments, namely current density (1?20 mA cm-2), solution pH value (2?10), initial concentration of SMX (10?500 mg L-1) and concentration of electrolytes (0.05?0.4 mol L-1). An artificial neural network (ANN) model was used to simulate this EO process. Based on the obtained model, particle swarm optimization (PSO) was used to optimize the operating parameters. The maximum removal efficiency of SMX was obtained at the optimized conditions (e.g., current density of 12.37 mA cm-2, initial pH value of 4.78, initial SMX concentration of 74.45 mg L-1, electrolyte concentration of 0.24 mol L-1 and electrolysis time of 51.49 min). The validation results indicated that this method can ideally be used to optimize the related parameters and predict the anticipated results with acceptable accuracy.

Authors: Stanojevic Ivana , Savic Nada , Crochet Aurélien , Fromm Katharina , Djuran Milos , Glisic Biljana
Published: March 2019

New polynuclear silver(I) complexes, [Ag(CF3SO3)(4,7-phen)(CH3CN)]n (1) and [Ag(PO2F2)(4,7-phen)]n (2), were synthesized by the reaction of 4,7-phenanthroline (4,7-phen) and the corresponding AgX salt (X = CF3SO3 - and PF6 -) in 1:2 mole ratio, respectively, in methanol/acetone (1:1 volume ratio) at room temperature. The characterization of the complexes was established on the basis of elemental microanalysis, IR and NMR (1H and 13C) spectroscopic techniques, while their crystal structures were determined by single-crystal X-ray diffraction analysis. The results of spectroscopic and crystallographic analyses revealed that in these complexes, 4,7-phen behaves as a bridging ligand between two metal ions, while the remaining coordination sites of the Ag(I) ions are occupied by the oxygen atom of CF3SO3 - and an acetonitrile nitrogen atom in 1 or by two oxygen atoms from two PO2F2 -, formed after hydrolysis of PF6 -, in 2. In the solid state, both complexes are coordination polymers in which the geometry around the Ag(I) ions is distorted tetrahedral.
The developmental state in the 21st century: A critical analysis and a suggested way forward
Authors: Karaoğuz Emrah
Published: March 2019

A vast literature has accumulated on the developmental state since its introduction to scholarship in the 1980s. Despite many criticisms, developmental state is still the most viable alternative to the orthodoxy in the eyes of many. This article analytically investigates the sources of pessimism and optimism in the building of 21st century developmental states. The study notes that although there are sound reasons to be pessimistic regarding the emergence of successful cases in the new millennium, there are also reasonable grounds to be optimistic. A complex dynamic within and between domestic and international spheres determines the outcome, but there is no reason to disregard prematurely or embrace indisputably the developmental state construct.
Survey on the relation between road freight transport, SCM and sustainable development
Authors: Ech-Chelfi Wiame , El Hammoumi
Published: March 2019

In this work, we develop CASVM and CANN algorithms for semi-supervised classification problem. The algorithms are based on a combination of ensemble clustering and kernel methods. A probabilistic model of classification with the use of cluster ensemble is proposed. Within the model, error probability of CANN is studied. Assumptions that make probability of error converge to zero are formulated. The proposed algorithms are experimentally tested on a hyperspectral image. It is shown that CASVM and CANN are more noise resistant than standard SVM and kNN.
Ameliorating Methylglyoxal-Induced Progenitor Cell Dysfunction for Tissue Repair in Diabetes

Published: March 2019

Patient-derived progenitor cell (PC) dysfunction is severely impaired in diabetes, but the molecular triggers that contribute to mechanisms of PC dysfunction are not fully understood. Methylglyoxal (MGO) is one of the highly reactive dicarbonyl species formed during hyperglycemia. We hypothesized that the MGO scavenger glyoxalase 1 (GLO1) reverses bone marrow-derived PC (BMPC) dysfunction through augmenting the activity of an important endoplasmic reticulum stress sensor, inositol-requiring enzyme 1α (IRE1α), resulting in improved diabetic wound healing. BMPCs were isolated from adult male db/db type 2 diabetic mice and their healthy corresponding control db/+ mice. MGO at the concentration of 10 µmol/L induced immediate and severe BMPC dysfunction, including impaired network formation, migration, and proliferation and increased apoptosis, which were rescued by adenovirus-mediated GLO1 overexpression. IRE1α expression and activation in BMPCs were significantly attenuated by MGO exposure but rescued by GLO1 overexpression. MGO can diminish IRE1α RNase activity by directly binding to IRE1α in vitro. In a diabetic mouse cutaneous wound model in vivo, cell therapies using diabetic cells with GLO1 overexpression remarkably accelerated wound closure by enhancing angiogenesis compared with diabetic control cell therapy. Augmenting tissue GLO1 expression by adenovirus-mediated gene transfer or with the small-molecule inducer trans-resveratrol and hesperetin formulation also improved wound closure and angiogenesis in diabetic mice. In conclusion, our data suggest that GLO1 rescues BMPC dysfunction and facilitates wound healing in diabetic animals, at least partly through preventing MGO-induced impairment of IRE1α expression and activity. Our results provide important knowledge for the development of novel therapeutic approaches targeting MGO to improve PC-mediated angiogenesis and tissue repair in diabetes.

OBJECTIVE

The aim of this study was to investigate tissue-specific effects of dapagliflozin on insulin sensitivity and liver and body fat in patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

This randomized, double-blind, parallel group, placebo-controlled study recruited 32 patients with type 2 diabetes. Enrolled patients were to have HbA1c 6.5–10.5% (48–91 mmol/mol) and ≥3 months of stable treatment with metformin, dipeptidyl peptidase 4 inhibitor, or their combination. Patients were randomized 1:1 to receive 10 mg dapagliflozin or placebo daily for 8 weeks. Before and after the intervention, tissue insulin sensitivity was measured using [18F]-fluorodeoxyglucose and positron emission tomography during hyperinsulinemic-euglycemic clamp. Liver proton density fat fraction (PDFF) and adipose tissue volumes were assessed using MRI, and blood biomarkers were analyzed.

RESULTS

After 8 weeks, glycemic control was improved by dapagliflozin (placebo-corrected change in HbA1c −0.39%, P < 0.01), but whole-body glucose uptake was not increased (P = 0.90). Tissue-specific insulin-stimulated glucose uptake did not change in skeletal muscle, liver, myocardium, or white and brown adipose tissue, and endogenous glucose production remained unaffected. However, there were significant placebo-corrected decreases in liver PDFF (−3.74%, P < 0.01), liver volume (−0.10 L, P < 0.05), visceral adipose tissue volume (−0.35 L, P < 0.01), interleukin-6 (−1.87 pg/mL, P < 0.05), and N-terminal prohormone of brain natriuretic peptide (−96 ng/L, P = 0.03).

CONCLUSIONS

In this study, 8 weeks of treatment with dapagliflozin reduced liver PDFF and the volume of visceral adipose tissue in obese patients with type 2 diabetes. Although glycemic control was improved, no effect on tissue-level insulin sensitivity was observed.

La evaluación obligatoria del desempeño docente y su sentido para el profesorado de telesecundarias: entre el temor, control y sometimiento / The Required Evaluation for the Teacher's Performance and His Understanding of the Tele-Secondary Professorship: Fear, Control and Submission
Authors: Díaz Cano Fortino
Published: March 2019

La educación en México en los últimos años ha pasado procesos vertiginosos a partir de la reforma de 2013. Esta trajo modificaciones en lo laboral y administrativo, y sobre todo impuso la evaluación docente obligatoria. El objetivo de este trabajo fue analizar el sentido e implicaciones de la evaluación obligatoria del desempeño docente en el profesorado de telesecundarias. Se consideraron su función, los procesos y los alcances proyectados.La investigación se abordó a partir de la referencia teórica del concepto sentido de Luhmann (1998) y Schutz (citado en Natanson, 1962). El método utilizado fue la epistemología sistémica. Asimismo, se recurrió a la triangulación metódica mediante el uso de dos técnicas, a saber, cuatro entrevistas en profundidad y dos grupos de discusión llevados a cabo en 2017, para el análisis de la información recuperada de docentes evaluados en 2015-2016 de algunas escuelas telesecundarias del estado de Hidalgo. Por tanto, se trató de un estudio de caso.Los profesores representaron a la evaluación y a sus resultados como una complejidad. Por la orientación punitiva contenida en la ley, sintieron temor: la prueba determinaría su permanencia en el trabajo. Además, la vieron como un instrumento de control ineludible, los mantuvo con presión, ocupados en ella, estresados por la posibilidad de que fueran dados de baja. Lo anterior fue ejercido con un poder opresivo legal que les obligó a asumir prácticas de sometimiento, dieron por hecho que debían realizarlas sin otra opción, las aceptaron como algo dado e impuesto, todo con miras a preservar su trabajo: les ocasionó la sumisión total. También se redefinieron las relaciones de poder, se estableció una nueva dinámica laboral y administrativa. Finalmente, el punto central para el profesorado no estuvo en ser evaluados, lo consideraron necesario y benéfico para la educación, fueron las normas punitivas en las que se inscribió la evaluación, las cuales amenazaban su estabilidad, su estatus y su futuro laboral, lo que les hizo asignarle un sentido de temor y control: asociaron esas ideas con prácticas de sometimiento.

Utjecaj aspiracije traheje na nastanak nozokomijalnih pneumonija
Authors: Saratlija Mirjana
Published: March 2019

Nozokomijalna pneumonija vodeća je komplikacija liječenja djece u jedinicama intenzivne medicine, sa znatnim utjecajem na njihov mortalitet i morbiditet. Nastaje u približno 8 do 28 % strojno ventiliranih bolesnika, a učestalost joj se povećava za najmanje 1 do 3 %
po svakom danu trajanja strojne ventilacije. O prohodnosti dišnog puta ovisi kvaliteta disanja i izmjena plinova. Jedini je način održavanja prohodnosti dišnog puta pravodobna i učinkovita aspiracija traheje. Aspiracijom uklanjamo sekret iz dišnog puta, pospješujemo respiratornu funkciju i sprječavamo sekundarnu infekciju pluća. Aspiracija se može provoditi otvorenim i zatvorenim sustavom. Otvorenim, klasičnim sustavom
aspiraciju provode dvije medicinske sestre. Zatvorenim sustavom aspirira jedna medicinska sestra, pacijent se ne odvaja od respiratora i
pri tome je smanjena mogućnost unosa patogena iz vanjske okoline. Sam postupak aspiracije zatvorenim sustavom ima nekoliko koraka kojih se treba pridržavati kako bi aspiracija bila uspješna. Potrebno je odrediti
pravu veličinu zatvorenog sustava u odnosu na veličinu tubusa, pravilno
izmjeriti distancu i pridržavati se zadanih mjera i postupaka prilikom aspiracije.
Socijalna skrb u zajednici za starije osobe u socijalnom riziku
Authors: Župan Alen
Published: March 2019

Nužnost izgradnje politika i mjera socijalne skrbi prilagođenih potrebama osobama starije životne dobi prioritet je društvenih struktura. Važno je prevenirati socijalnu isključenost starijih osoba, održavati primjereni životni standard umirovljenika, promicati međugeneracijsku solidarnost i produžiti aktivnu životnu dob. Porast broja starijih osoba u socijalnom riziku i potrebe iz kojih proizlazi njihova ovisnost o drugim osobama i općenito zajednici potiču na razvoj novih neposrednih i multidisciplinarnih izvan institucijskih modela socijalnih usluga. Važno je rano intervenirati u detekciji starijih osoba u socijalnom riziku i osigurati širu dostupnost usluga u zajednici
istodobno suzbijajući siromaštvo i podupirući socijalnu uključenost ugroženih skupina te veću razinu socijalne sigurnosti starijih osoba uz poboljšanje pristupa održivim i visokokvalitetnim socijalnim uslugama, uključujući podršku procesu deinstitucionalizacije.
