Serbian Translation and Cross-Cultural Validation of the Questionnaire for Assessing Patient Satisfaction with Endoscopic Examination of the Digestive Tract
Authors: Nikolic Bosko , Jankovic Slobodan M.
Published: November 2017

Patient satisfaction is a key indicator to assess the quality of gastrointestinal endoscopy. The aim of this study was to examine the Serbian translation and cross-cultural validation of the questionnaire for the assessment of satisfaction in patients who underwent gastrointestinal endoscopy.

After obtaining the consent of the author of the original questionnaire, translation and cross-cultural validation of the GESQ (Gastrointestinal Endoscopy Satisfaction Questionnaire) were carried out in accordance with the conductors of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR). The study was conducted in the Center for Gastroenterohepatology (GEH) of the Kragujevac Clinical Center and included 165 patients. The reliability of the Serbian translation of the GESQ was estimated by calculating Cronbach’s alpha for the whole questionnaire in order to implement the structural validation. The overall score of the questionnaire was compared and correlated with the total scores on the Short Subjective Well-being scale (KSB) and visual analogue scale (VAS), which were administered to the same patients.

The Serbian translation of the GESQ showed high reliability with a Cronbach’s alpha coefficient of 0.763, good structure and homogeneity by randomly sharing the questionnaire into two parts. Exploratory factor analysis indicated the existence of four factors that explain 57.200% of the variability.

The Serbian version of the GESQ showed similar psychometric characteristics to the original English questionnaire, with a similar factor structure, and represented a valid, reliable and acceptable tool for the assessment of patient satisfaction with the endoscopic examination of the digestive tract.
EM algorithm for Markov chains observed via Gaussian noise and point process information: Theory and case studies
Authors: Damian Camilla , Eksi Zehra , Frey Rüdiger
Published: November 2017

In this paper we study parameter estimation via the Expectation Maximization (EM) algorithm for a continuous-time hidden Markov model with diffusion and point process observation. Inference problems of this type arise for instance in credit risk modelling. A key step in the application of the EM algorithm is the derivation of finite-dimensional filters for the quantities that are needed in the E-Step of the algorithm. In this context we obtain exact, unnormalized and robust filters, and we discuss their numerical implementation. Moreover, we propose several goodness-of-fit tests for hidden Markov models with Gaussian noise and point process observation. We run an extensive simulation study to test speed and accuracy of our methodology. The paper closes with an application to credit risk: we estimate the parameters of a hidden Markov model for credit quality where the observations consist of rating transitions and credit spreads for US corporations.
National Competitiveness through the Europe 2020 Strategy and Human Development Index in CEE Countries. A Panel Data Analysis
Authors: Talmaciu Ana Maria , Cismas Laura Mariana
Published: November 2017

In the new innovation economy, national competitiveness is an expression of the quality of the human capital and of the capacity to attract and retain the talent. In this paper, we propose to verify the link between the national competitiveness and the human capital, measured by the public expenditure on tertiary education and by the public expenditure on research and development. The research methodology uses the Panel Data method for Central and Eastern European countries by analyzing data on competitiveness scores in the Europe 2020 Report 2014, the Human Development Index 2015, the Global Competitiveness Report 2016 and those on public expenditure on tertiary education and by the public expenditure on research and development, corresponding to the period 2010-2014. The objectives of this paper are: synthesis of theoretical delimitations on competitiveness, highlighting the relationship between national competitiveness and human capital, testing this relationship for the case of Central and Eastern European countries. The results show a significant and a positive relation, indicating that investment in education and research contributes significantly to increasing the national competitiveness. The obtained results draw attention to the fact that Central and Eastern Europe countries need to initiate measures to reduce the drain-brain phenomenon and to create a favorable socio-economic context for retaining and attracting the talent.

Authors: Nakamura Yoko , Paetz Christian , Boland Wilhelm
Published: November 2017

(9Z)-Methyl 4-dihydrotrisporate B and (9Z)-methyl trisporate B, pheromones of Zygomycetes fungi, have been synthesized using Stille cross-coupling from previously described cyclohexenone precursors. Conducting the coupling without protection groups allowed for a short and stereospecific synthesis route of the late trisporoids. Stability studies for both the compounds revealed (9Z)-methyl trisporate B to be very unstable against UV irradiation.

Stone, MS, Glenn, JM, Vincenzo, JL, and Gray, M. Comparison of exercise performance in recreationally active and masters athlete women. J Strength Cond Res 32(2): 565–571, 2018—Master athletes (MA) are an understudied, ever-growing cohort. As such, it is important to examine how age affects muscular power and fatigability. Of particular interest is muscular power maintenance and fatigue mitigation of MA compared with young, healthy adults. The purpose of this investigation was to examine the differences in peak power, average power, total work (WRK), and fatigue index (FI) between recreationally active (RA) younger adults and female MA during anaerobic cycling exercise. Two groups, RA (n = 15; 20.6 ± 0.8 years) and MA (n = 17; 50.5 ± 8.6 years), participated in this study. Peak power, APWR, WRK, and FI were measured during a 30-second Wingate maximum anaerobic cycling protocol at a predetermined resistance of 7.5% body mass. Peak power (p = 0.92; RA: 654.1 ± 114.5 W; MA: 658.6 ± 147.6 W), APWR (p = 0.09; RA: 429.8 ± 73.3 W; MA: 384 ± 73.8 W), WRK (p = 0.09; RA: 12,894.3 ± 2,198.3 J; MA: 18,044.3 ± 27,184.9 J), and FI (p = 0.30; RA: 11.8 ± 4.1 W·s−1; MA: 14 ± 5.2 W·s−1) were not significantly different between groups. Master athletes produce power and WRK comparable to rates of fatigue among RA. This suggests that MA can maintain physical ability similar to RA in multiple parameters of high-intensity exercise while mitigating fatigue comparably. These data allow for advancements in exercise training and performance outcomes in MA populations. Further research within the MA population is warranted regarding other aspects of exercise and sport performance.

Otaegi, A and Los Arcos, A. Quantification of the perceived training load in young female basketball players. J Strength Cond Res 34(2): 559–565, 2020—The purposes of this study were (a) to compare training session, match, and weekly perceived training load (TL) between U15 and U16 female basketball players and (b) within the teams, to assess the relationship between perceived TL and the changes in physical fitness performance during an in-season 9-week period. Twenty-one female players from U15 and U16 female teams from the same Spanish club participated in the study. Before and after the study, players were tested to determine physical fitness performance (using Yo-Yo IR1, countermovement jump, T-Test, and 15 m sprint). Each player declared her perceived exertion (PE) for the whole training session and match using Foster's 0–10 scale. Training week perceived TL was higher for the U16 players than the U15 players; U16 players considered the training and matches to be more difficult. In both teams, the perceived TL of the last training session of the week was significantly lower (Effect sizes = large–very large) than the other sessions. Although substantial negative associations (r = 0.52–0.78) were detected between the changes in physical fitness performance and the accumulated volume, sum of PEs and perceived TL in the U15 players, these associations were unclear in the U16 players. The basketball coaches-periodized training goals are to attain the highest session perceived TLs in the middle of the week and to reduce it considerably in the last training session. The U16 and U15 players accumulated perceived TL in different ways. Although the practice volume was similar in both teams, the older players consider the sessions more difficult. The relationship between the perceived TL and the changes in physical fitness performance varied between teams. Based on our findings, we propose that the PE-based dose-response model should be applied with caution in young female basketball players.
Split Estate and Wyoming’s Orphaned Well Crisis: The Case of Coalbed Methane Reclamation in the Powder River Basin, Wyoming
Authors: Bills Walsh Kathryn
Published: November 2017

This case presents the stakeholder conflicts that emerge during the development and subsequent reclamation of abandoned natural gas wells in Wyoming where split estate, or the separation of surface land and mineral rights from one another, occurs. From 1998 to 2008, the Powder River Basin of northeastern Wyoming experienced an energy boom as a result of technological innovation that enabled the extraction of coalbed methane (CBM). The boom resulted in over 16,000 wells being drilled in this 20,000 square-mile region in a single decade. As of May 2017, 4,149 natural gas wells now sit orphaned in Wyoming as a result of industry bankruptcy and abandonment. The current orphaned wells crisis was partially enabled by the patchwork of surface and mineral ownership in Wyoming that is a result of a legal condition referred to as split estate. As the CBM boom unfolded in this landscape and then began to wane, challenges emerged most notably surrounding stalled reclamation activities. This case illuminates these challenges highlighting two instances when split estate contributed to issues between landowners and industry operators which escalated to litigation.

A Deconvolution Protocol for ChIP-Seq Reveals Analogous Enhancer Structures on the Mouse and Human Ribosomal RNA Genes
Authors: Mars Jean-Clement , Sabourin-Felix Marianne , Tremblay Michel G , Moss Tom
Published: November 2017

The combination of Chromatin Immunoprecipitation and Massively Parallel Sequencing, or ChIP-Seq, has greatly advanced our genome-wide understanding of chromatin and enhancer structures. However, its resolution at any given genetic locus is limited by several factors. In applying ChIP-Seq to the study of the ribosomal RNA genes, we found that a major limitation to resolution was imposed by the underlying variability in sequence coverage that very often dominates the protein–DNA interaction profiles. Here, we describe a simple numerical deconvolution approach that, in large part, corrects for this variability, and significantly improves both the resolution and quantitation of protein–DNA interaction maps deduced from ChIP-Seq data. This approach has allowed us to determine the in vivo organization of the RNA polymerase I preinitiation complexes that form at the promoters and enhancers of the mouse (Mus musculus) and human (Homo sapiens) ribosomal RNA genes, and to reveal a phased binding of the HMG-box factor UBF across the rDNA. The data identify and map a “Spacer Promoter” and associated stalled polymerase in the intergenic spacer of the human ribosomal RNA genes, and reveal a very similar enhancer structure to that found in rodents and lower vertebrates.
Global Transcriptome Sequencing Reveals Molecular Profiles of Summer Diapause Induction Stage of Onion Maggot, Delia antiqua (Diptera: Anthomyiidae)
Authors: Ren Shuang , Hao You-Jin , Chen Bin , Yin You-Ping
Published: November 2017

The onion maggot, Delia antiqua, is a worldwide subterranean pest and can enter diapause during the summer and winter seasons. The molecular regulation of the ontogenesis transition remains largely unknown. Here we used high-throughput RNA sequencing to identify candidate genes and processes linked to summer diapause (SD) induction by comparing the transcriptome differences between the most sensitive larval developmental stage of SD and nondiapause (ND). Nine pairwise comparisons were performed, and significantly differentially regulated transcripts were identified. Several functional terms related to lipid, carbohydrate, and energy metabolism, environmental adaption, immune response, and aging were enriched during the most sensitive SD induction period. A subset of genes, including circadian clock genes, were expressed differentially under diapause induction conditions, and there was much more variation in the most sensitive period of ND- than SD-destined larvae. These expression variations probably resulted in a deep restructuring of metabolic pathways. Potential regulatory elements of SD induction including genes related to lipid, carbohydrate, energy metabolism, and environmental adaption. Collectively, our results suggest the circadian clock is one of the key drivers for integrating environmental signals into the SD induction. Our transcriptome analysis provides insight into the fundamental role of the circadian clock in SD induction in this important model insect species, and contributes to the in-depth elucidation of the molecular regulation mechanism of insect diapause induction.

Nesse ensaio, produzimos alguns conceitos para refletirmos sobre a semiformação do produtivismo acadêmico fundamentado em uma espécie de mentalidade do ticket “às avessas” e a produção do que optamos por nomear de “preconceito integrativo”. Desse modo, os conceitos elaborados nesse ensaio são: “Tempo Stand By”, “Pré-atenção induzida”, “Hiperatenção fluida”, “Intelectual online”, “ (Auto)imagem como autoria”.
Reflexões sobre mundo digital e subjetividade
Authors: Antunes Deborah Christina
Published: November 2017

O objetivo do presente ensaio é apresentar questões urgentes sobre a relação entre o mundo digital que configura nossa sociedade atual, a partir do avanço ao acesso às tecnologias computacionais, e a emergência de subjetividades específicas que respondem antropologicamente aos aparatos que fomentam sua realização. Inicio ao trazer para reflexão crítica o conceito de digital a partir da ideia de dígitos, sua lógica matemática clássica e contraposição ao analógico, avançando para a ideia insurgente de computação quântica, e apresento a necessidade de se pensar essas questões a partir de uma teoria crítica da tecnologia. Sigo trazendo aspectos históricos do desenvolvimento dos meios de comunicação, que ajudam a compreender como, embora cada nova tecnologia de comunicação tenha surgido com a promessa de emancipação e liberdade, tal promessa jamais foi realizada, na medida em que o modo de produção em voga direciona seu desenvolvimento em prol de sua manutenção. Tal direcionamento não ocorre apenas para com os artefatos, mas com eles e através deles, também em relação ao desenvolvimento das subjetividades aqui e agora, no surgimento dos computer people como tipo antropológico da sociedade digital, correlato à geração do rádio, pensado por Theodor W. Adorno nos anos 1930. Finalizo pensando as possibilidades de práxis frente às questões colocadas.

Piled foundations and pathways for ground gas migration in the UK
Authors: Wilson Steve , Mortimer Sarah
Published: November 2017

Piled foundations are commonly thought to create preferential pathways for ground gas migration. This view is often held without consideration of site-specific ground conditions, pile type or source of gas. There are currently no published data that quantify the effects of piles on gas flow from the ground. Both contaminated water and gas are fluids that for the purposes of this paper can be modelled using the standard equations of fluid flow. Therefore, the available research on the risk of piles increasing the permeability of the surrounding ground with respect to contaminated water can also be applied to gas flow. This paper discusses the different types of pile construction commonly used in the UK and how each may, or may not, influence gas migration. Understanding ground conditions is critical to assessing whether a preferential pathway will form. This paper looks at the available evidence on the influence of piles on the permeability of the surrounding ground. Even if it is considered possible that a preferential pathway could develop, the influence on the gas risk will depend on the number of piles, gas pressure and horizontal permeability. A significant effect is possible only where gas is under pressure and/or the piles are very closely spaced.
Addressing Psychological Mechanisms of Personality Development in Educational Environment Design
Authors: Khodyakova N.V. , Mitin A.I.
Published: November 2017

The paper discusses the problems and ways of implementing in educational design the relevant educational paradigm that focuses on personality development in students. The authors analyse various approaches in psychology and pedagogics to the phenomenon of educational environment and its special role in personality development of individuals. As it is shown, personality development in students occurs in the process of their situational interaction with educational environment and as a result of actualization of specific psychological mechanisms. The paper provides a typology of situations of personality development in educational environment (cognitive orientation; object and activity orientation; values and meaning orientation; holistic orientation).Each type of situation corresponds with its own basic psychological mechanisms of personality development. It is argued that the major psychological mechanisms of each of the four types of personality development situations are interrelated following the principle of complementing outer activity of the student with inner activity.
Tráfico artístico cortesano: El paso franco de obras de arte por el Reino de Aragón en el siglo XVII
Authors: López Conde Rubén
Published: November 2017

El examen de los pasaportes expedidos durante el siglo XVII por el Consejo de Aragón nos ha permitido conocer el envío o tránsito por el país de un buen número de piezas artísticas remitidas por o destinadas a la corte madrileña. La mayoría de los documentos reunidos refiere envíos que atañen a los sitios y palacios del rey, al coleccionismo cortesano y al trasegar de obras de arte pertenecientes a personajes principales de la política de su tiempo. Solo unos pocos registros afectan a remesas ya consignadas en las cédulas de paso de la Cámara de Castilla –las únicas que hasta ahora se habían estudiado en profundidad–, si bien la información transmitida no siempre es la misma, siendo así que, en ocasiones, la documentación aragonesa avanza e incluso enmienda los datos aportados por la castellana.
Un cuadro inédito de San Miguel Arcángel, obra de Giacomo Farelli, en Alcalá de Henares
Authors: Llull Peñalba Josue
Published: November 2017

En este artículo se da a conocer la existencia de un cuadro, hasta ahora inédito, que representa a San Miguel Arcángel venciendo al demonio. Es propiedad de la congregación de los Hermanos Maristas y se conserva en su casa provincial de Alcalá de Henares. Una reciente restauración ha permitido atribuirlo a Giacomo Farelli, artista barroco vinculado a la Escuela Napolitana de Pintura de la segunda mitad del siglo XVII. El cuadro tiene un notable interés por su calidad y por la escasez de obras de Farelli que hay en España. La publicación de este trabajo de investigación pretende contribuir a un mayor conocimiento de la figura de este pintor y de las fructíferas relaciones histórico-artísticas desarrolladas entre España e Italia.

La tendencia a la desmaterialización del arte durante el siglo XX verá su culminación definitiva enel desarrollo de los nuevos medios digitales actuales. Con ellos las creaciones artísticas acentuarán la carga de la informacióncontenida sobre cualquier otro elemento físico. Los medios quedarán reducidos a materializadores circunstancialesde las obras. En este contexto, dominado por la rápida obsolescencia de las nuevas tecnologías, la cuestión serála de las posibles estrategias de conservación de las obras de cara al futuro. El patrimonio cultural digital producido ennuestros días corre un peligro constante de pérdida. Ante ello debe redifinirse el papel de la institución, un medio ya noalmacenador de creaciones moribundas, sino punto neurálgico que debe mantener abierto el proceso de comunicacióncon el público-usuario.

Romanticismo y romanticismos en los grabados de la revista artística No Me Olvides (1837-1838)
Authors: Álvarez Rodríguez María Victoria
Published: November 2017

Durante los primeros años del reinado isabelino asistimos en España al surgimiento de las publicaciones periódicas dedicadas a las Bellas Artes. Estrechamente relacionadas en la década de 1830 con el Romanticismo que estaba empezando a calar en el país, con el paso de los años acabaron convirtiéndose en unas revistas menos exaltadas cuya gran aspiración era atraer a un número cada vez mayor de lectores. La revista No Me Olvides fue una de las que mejor recogió esos arrebatados postulados de los escritores y artistas del primer Romanticismo, algo apreciable tanto en sus textos como en los grabados que los acompañaban. En el presente artículo abordaremos el análisis de dichas estampas atendiendo al acercamiento de cada grabador a un romanticismo distinto, moviéndose entre la herencia del academicismo, el costumbrismo, el goticismo o el sentimentalismo.

Published: November 2017

It remains the primary issue to enhance the corrosion resistance of Mg alloys for their clinical applications. In this study, β-tricalcium phosphate (β-TCP) was composited with Mg-6Zn-1Zr (ZK60) using laser rapid solidification to improve the degradation behavior. Results revealed rapid solidification effectively restrained the aggregation of β-TCP, which thus homogenously distributed along grain boundaries of α-Mg. Significantly, the uniformly distributed β-TCP in the matrix promoted the formation of apatite layer on the surface, which contributed to the formation of a compact corrosion product layer, hence retarding the further degradation. Furthermore, ZK60/8β-TCP (wt. %) composite showed improved mechanical strength, as well as improved cytocompatibility. It was suggested that laser rapidly solidified ZK60/8β-TCP composite might be a potential materials for tissue engineering.
Coaxial nozzle-assisted electrohydrodynamic printing for microscale 3D cell-laden constructs
Authors: Liang Hongtao , He Jiankang , Chang Jinke , Zhang Bing , Li Dichen
Published: November 2017

Cell printing has found wide applications in biomedical fields due to its unique capability in fabricating living tissue constructs with precise control over cell arrangements. However, it is still challenging to print cell-laden 3D structures simultaneously with high resolution and high cell viability. Here a coaxial nozzle-assisted electrohydrodynamic cell printing strategy was developed to fabricate living 3D cell-laden constructs. Critical process parameters such as feeding rate and stage moving speed were evaluated to achieve smaller hydrogel filaments. The effect of CaCl2 feeding rate on the printing of 3D alginate hydrogel constructs was also investigated. The results indicated that the presented strategy can print 3D hydrogel structures with relatively uniform filament dimension (about 80 μm) and cell distribution. The viability of the encapsulated cells was over 90%. We envision that the coaxial nozzle-assisted electrohydrodynamic printing will become a promising cell printing strategy to advance biomedical innovations.
Effectiveness of ligation of intersphincteric fistula tract (LIFT) in the management of fistulas in ano
Authors: Rohit Dushyant Kumar , Jain Sarvesh , Pandey Grishmraj
Published: November 2017

Background: Fistula in ano is an abnormal connection between the epithelized surface of anal canal and usually the perianal skin. It is a benign treatable lesion of rectum and anal canal. Crypto glandular infection accounts for about ninety percent of the cases. The estimated prevalence of an anal fistula is 12 to 28/1000000 of the population per year with male to female ratio 1.8:1. Ligation of intersphincteric fistula tract is a new sphincter saving method with good result in the management of anal fistula. The aim of study was to evaluate the effectiveness and functional outcomes of the ligation of intersphinteric fistula tract (LIFT).Methods: This prospective study includes sixteen patients who were operated for fistulas in ano at Bundelkhand Medical College and Associated Hospital, Sagar from January 2015 to June 2017. Patients above the age of 20 years, proved cases of fistulas in ano without co-morbid conditions and no previous surgical intervention were included in the study. Patients presenting with fistulas from another source such as crohn’s disease, tuberculosis, anal cancer and recurrent fistulas were excluded. A detailed history, clinical presentation, digital rectal examination, anal ultrasound and routine investigations were done in all cases.Results: In the present study most of the patients were male and presents with perianal discharge. The diagnosis is made by clinical history, per rectal examination and anal ultrasonography. All the sixteen patients with fistula in ano underwent ligation of intersphincteric fistula tract (LIFT). The patients were followed for a period of three months. Most of the cases (87.5%) healed within 4-6 weeks. The recurrence of fistula occurs in four cases (25%). Recurrence is due to infection and technical error in the procedures. There were no deaths in the study.Conclusions: The LIFT technique proved to be safe and effective in the treatment of fistula in ano.

Resumo: este artigo tem como objetivo apresentar as conceituações contemporâneas dos Movimentos Sociais, assim como problematizar as suas atuações e perspectivas de formação dentro dos parâmetros da base marxiana como método. Identificar-se-ão os processos de consciência, que dualizam entre a emancipação e a constituição da Ideologia, esta última, como uma das formas emanadas de percepção do mundo. Apontamos os tensionamentos entre Trabalho e Capital como categorias, ainda, inexoráveis de constatação do resultado extrator do trabalho vivo pelo capitalismo, e da tentativa de uma epistemologia pós-moderna de “responder” à modernidade. Apresentamos possibilidades da desfetichização como direcionamentos e pautas na formação política dos sujeitos que, assim, interagem com os diversos grupamentos societários. As conclusões levam-nos a uma perspectiva radicalizada de aprofundamentos das lutas sociais, que levem em consideração a totalidade dos envolvimentos e da necessidade de articulação das convergências dentro das diversas temáticas protagonizadas pelos Movimentos Sociais.Palavras-chave: Movimentos Sociais.

Objetivo: describir las características de los procesos de comunicación y coordinación en el rol interdependiente de enfermería y determinar si hay diferencias significativas entre estos procesos en los distintos servicios de un hospital en Bogotá.
Metodología: estudio descriptivo de corte transversal, en el que se utilizaron las escalas de Comunicación y Coordinación del Cuestionario de Práctica Colaborativa ICU Médico-Enfermera en su versión validada al español colombiano. El instrumento se aplicó a 124 profesionales (87 % mujeres con edad promedio de 34,1 años). Se usaron puntajes (de 0 a 100) con el fin de presentar los resultados de las dimensiones y realizar las pruebas de Tukey (diferencia mínima significativa) y Kruskal Wallis para establecer relaciones de diferencia y correlación por medio de SPSS 14.0.
Resultados: las dimensiones más problemáticas fueron: Exactitud de lacomunicación entre los grupos (promedio de 47,8 puntos) en cuanto a comunicación, y Mecanismos de coordinación personales e informales entre la unidad (promedio de 51,8 puntos) en cuanto a coordinación, con diferencias significativas en la dimensión de  Comunicación (p = 0,031), principalmente de Urgencias y Hospitalización con relación a los otros servicios.
Conclusión: se evidenciaron problemas en la comunicacióny la coordinación, lo cual implica ruptura en la cohesión, fragmentación de la atención y riesgo para la seguridad de los pacientes. Se recomienda promover estrategias de comunicación efectiva y coordinación interprofesional, así como fortalecer el liderazgo y el trabajo en equipo.

Objetivo: determinar la relación entre hábitos alimentarios y la presencia de síntomas digestivos altos en estudiantes de la Universidad Nacional de San Luis.
Metodología: estudio transversal descriptivo, en el cual participaron 150 sujetos (mujeres = 86, hombres = 64), estudiantes de 20 a 30 años de edad, de la Universidad Nacional de San Luis, sede San Luis; se utilizó una encuesta validada del Ministerio de Desarrollo Social de Argentina, adaptada a los fines de la presente investigación.
Resultados: la mayoría de los estudiantes consume casi siempre las cuatro comidas principales; las formas de cocción predominantes fueron: horno, plancha y hervido. Se observó escasa y poco variada selección de frutas y verduras, un consumo ocasional de bebidas alcohólicas y de productos ricos en grasas, sal y azúcares. La elección de dulces y azúcares, mate cebado, té y café fue elevada. Los síntomas más recurrentes fueron: distensión abdominal, hambre dolorosa, regurgitación, náuseas y pirosis; los que menos aparecieron fueron vómito y anorexia. Los estudiantes asociaron la recurrencia de los síntomas al consumo de comidas con salsa, comidas picantes, mate cebado, té y café. En el sexo masculino, las bebidas alcohólicas también se asociaron a la sintomatología digestiva.
Conclusiones: se pudo observar la presencia de más de un síntoma digestivo alto simultáneo en cada estudiante, unido a la presencia de hábitos alimentarios perjudiciales. Por ello, es indispensable impartir educación alimentaria nutricional.

Automatic Analysis and Telemetry of Patients Affected by COPD
Authors: Adhithiya N. , Sukanesh R.
Published: November 2017

Chronic Obstructive Pulmonary Disease (COPD) is an umbrella term for a number of diseases including emphysema, bronchitis and asthma and so on. The severity of the disease can be identified by finding the peripheral oxygen saturation (SpO2) level. This level can be decomposed into trend components to analyse the deterioration in condition of patients affected by COPD. The condition can be analysed on daily, weekly and monthly basis. Message is sent to the clinical attendant of the patient when the condition becomes very abnormal.
From Nuremberg to Guantanamo Bay: Uses of Physicians in the War on Terror
Authors: Crosby Sondra S. , Benavidez Gilbert
Published: November 2017

Seventy years after the Nuremberg Doctors’ Trial, health professionals and lawyers working together after 9/11 played a critical role in designing, justifying, and carrying out the US state-sponsored torture program in the CIA “Black Sites” and US military detention centers, including Abu Ghraib, Bagram, and Guantanamo Bay, Cuba.

We analyze the similarities between the Nazi doctors and health professionals in the War on Terror and address the question of how it happened that health professionals, including doctors, psychologists, physician assistants, and nurses, acted as agents of the state to utilize their medical and healing skills to cause harm and sanitize barbarous acts, similar to (though not on the scale of) how Nazi doctors were used by the Third Reich.
Recommendations to Reduce Risk of Nerve Injury During Bernese Periacetabular Osteotomy (PAO)
Authors: Kalhor Morteza , Collado Diego , Leunig Michael , Rego Paulo , Ganz Reinhold
Published: November 2017

The Bernese periacetabular osteotomy (PAO) is a widely used procedure to reorient a dysplastic acetabulum resulting from developmental dysplasia of the hip, retroversion, protrusio, or some deformities with a traumatic etiology. Throughout the execution, the lateral femoral cutaneous nerve (LFCN) as well as the obturator, femoral, and sciatic nerves can be injured. Injury to 1 of the 3 major nerves is a devastating event for the patient followed by an ill-defined period of hope for nerve recovery and fear of lifelong disability. Surgical experience is an essential factor in reducing the prevalence of nerve injury, whereas proof of the value of intraoperative fluoroscopy and nerve monitoring still must be established. Although it is known that, for example, the ischial cuts of the complex osteotomy place the sciatic nerve at risk, the action causing the nerve injury is rarely clear in the individual situation. The literature has been mostly limited to reports of incidence and offers little analytic information.

Through the use of cadaveric dissections, we visualized the possible impacts of the different steps of the procedure on the nerves in their anatomic vicinity, and the present report demonstrates how nerves can be protected with retractor positioning and how lower-limb positioning can lead to nerve relaxation, an important means to avoid mechanical injury. While the frequent injuries of the LFCN are exclusively related to the approach, sciatic nerve injuries are mainly the result of the ischial osteotomy steps and femoral nerve injuries are seen nearly exclusively with the correction of the acetabular fragment. The authors implemented the demonstrated measures for 9 years, during which approximately 800 periacetabular osteotomies resulted in a total of 2 femoral and 2 sciatic nerve lesions—or a nerve injury rate of 0.5%. The nerves injuries resolved within 6 to 9 months in 3 hips, and 1 patient had a definitive foot drop requiring a splint at the time of writing.

Authors: Osayande Augustine , Mallo Ishaku Ibrahim Yari
Published: November 2017

The issue of gully erosion is of major concern in Nigeria. The study was carried out in Edo state, Southern Nigeria. Edo State was chosen as the study area due to the fact that the magnitude of gully erosion has resulted in the loss of lives and properties, destruction of arable lands and wastage of large areas of usable land. In this study, an effort was made to identify the major gully sites in the area and determined the mean rate of gully head advancement. The result revealed that gullies in Edo North had mean rate of head advancement of 80.30 meters per a year, Edo South 52.03 meters per a year and Edo Central is 17.80 meters per year.
Complementary relationship estimation of actual evapotranspiration in extreme cold and arid areas: a case study of the Hotan River Basin, northwest China

Application of complementary relationship (CR) approaches using only routine meteorological data is a very convenient method of estimating actual evapotranspiration (ETa). Reanalysis datasets and remote sensing data provide good tools to overcome the difficulties in obtaining observation data. This study of the Hotan River Basin (HRB) in northwest China serves as a prime example for estimation of ETa during 2006–2014 by using the modified generalized CR. Based on comparison and analysis, the maximum potential evaporation calculated by the Penman-based equation was adopted. The estimated ETa rates were verified using a regional water balance method at annual time scales because of the limited available data. The calibration parameter was calibrated based on the elevation and underlying surface types. The mean annual ETa ranged from 2.3 mm to 800 mm during 2006–2014. ETa rates in the plains regions were higher than those in the mountainous regions. Most of ETa was concentrated in the months of May to September. A water deficit occurred in the middle and lower regions, while a water surplus occurred in the upper regions. This study not only provided a new concept for calibration, but also a potential solution for different underlying surfaces and time scales.
Presence of Waddlia chondrophila in hot water systems from non-domestic buildings in France

The presence of Waddlia chondrophila has been related to respiratory tract infections and human and animal fetal death. Although several sources of infection have been suggested, the actual source remains unknown and limited information exists on the prevalence of W. chondrophila in the environment. This pathogen has been previously detected in well water but its presence has not been confirmed in water networks. Since these bacteria have been detected in water reservoirs, it has been hypothesized that they can access artificial water systems and survive until they find appropriate conditions to proliferate. In this work, their presence in water samples from 19 non-domestic water networks was tested by quantitative polymerase chain reaction (qPCR). Approximately half of the networks (47%) were positive for W. chondrophila and the overall results revealed 20% positive samples (12/59). Furthermore, most of the samples showed low concentrations of the pathogen (<200 genomic units/L). This finding demonstrates that W. chondrophila can colonize some water networks. Therefore, they must be considered as potential infection sources in future epidemiological studies.
