Sospensione delle cure in pediatria: il pain principle, una scelta rispettosa della vita e della sofferenza / Withdrawal of care in pediatrics: the pain principle, respectful of life and suffering
Authors: Bellieni Carlo
Published: October 2018

Il dibattito sul fine-vita in pediatria negli ultimi tempi ha mostrato di incagliarsi quando viene usato come principio decisionale il cosiddetto best interest del bambino, dato che esso è solitamente invocato sia dai fautori della prosecuzione delle cure sia da quelli della sospensione. Il best interest è un principio troppo elastico per essere usato in maniera semplice e rispettosa della vita e della dignità del paziente in maniera inequivocabile. In questo articolo si propone un protocollo chiamato “pain principle”, che a) misura il livello di sofferenza del soggetto, valuta se questa sia eliminabile, e in caso di dolore insopportabile passa al punto b): la diminuzione dell’intensità e invasività delle cure. Questo protocollo ha il vantaggio di evitare la sofferenza inutile, di ridurre al minimo il soggettivismo delle scelte e di non provocare mai intenzionalmente la morte del paziente, rispettandone al tempo stesso la dignità. ---------- The debate on end-of-life in pediatrics has recently proved to be stranded when the so-called best interest of the child is used as a decision-making principle, since it is usually invoked by both advocates of treatment and those of suspension. The best interest is a principle too elastic to be used in an unequivocal manner. In this article we propose a protocol called “the pain principle”, which imposes to a) measure the level of suffering of the subject, assesses whether this is eliminable, and – in the case of unbearable pain – b): to decrease intensity and invasiveness of care. The pain protocol has the advantage of avoiding unnecessary suffering, of minimizing the subjectivism of choices and of never intentionally causing the patients’ death, respecting their dignity as well.

Cardiac rehabilitation is the sum of psychological, physical and social treatments that are offered to cardiac patients to maintain or regain an active position in society. This study wants to evaluate changes in the perception of the illness and in the self-efficacy of the management of positive and negative emotions in patients who went through cardiac rehabilitation. Sixty-seven patients (20 females, 47 males) were selected within the cardiac rehabilitation unit in the Hospital of Cittadella (Italy). Illness Perception Questionnaire - revised version and the Scale for the self-efficacy of the management of positive and negative emotions were submitted at the beginning and at the end of the rehabilitation program. One-way analyses-of-variance were performed to evaluate different answers in questionnaires between pre- and post-evaluation, and to explore gender differences. A significant change was found in the perception of duration of illness, perceived as permanent and longer after the cardiac rehabilitation program. Furthermore, at the end of the cardiac rehabilitation program men perceived the illness more chronic than women, even if they are less worried and anxious. Intensive cardiac rehabilitation has a great emotional impact on cardiac patients, influencing their perception and management of the illness. Working on emotions, through psychological groups, helps patients change their beliefs by offering them a different perspective to approach the illness.
Motivational factors for engaging in dirty work entrepreneurship among a sample of African immigrant entrepreneurs in South Africa
Authors: Cobbinah Charles , Chinyamurindi Willie T.
Published: October 2018

Orientation: South Africa is witnessing a large number of African immigrants coming into the country. These immigrants seek formal and informal employment. One sector favoured is ‘dirty work’ within the informal sector.Research purpose: To investigate the immigrants’ motivational factors influencing migration and dirty work entrepreneurship in South Africa.Motivation for the study: Because of the dynamic nature of political and economic circumstances that affect a country’s employment options, calls have been made for empirical focus on understanding the career development processes of neglected sample groups such as immigrants and even those engaged in dirty work.Research approach/design and method: A qualitative research approach was utilised based on the narratives and stories of 27 immigrant entrepreneurs in the informal sector engaged in dirty work careers.Main findings: Three narratives emerged as motivating factors for migrating: (1) socio-economic issues, (2) lack of opportunities and (3) experience of a new life. Furthermore, three motivational factors led into dirty work careers: (1) challenges of breaking into formal employment because of immigration rules, (2) motivation from social networks the immigrants belong to and (3) an enterprising spirit, driven by ambition.Practical/managerial implications: Based on the findings, interventions can be proposed to assist not only those engaged in dirty work but also migrants and citizens seeking opportunities in this sector.Contribution/value add: This study advances the literature in dirty work research within a South African context. Further, the study gives currency to an often neglected yet important sample group in dirty work entrepreneurship, who also happen to be immigrants.

Published: October 2018

Hydrological simulation models have proven to be an important tool for managing and planning water resources, enabling the assessment of the impacts of rainfall on surface runoff and soil moisture. This work therefore aimed to apply the SWAT model for the analysis of hydrological processes in the Experimental Basin of the Jatobá Stream, in the semiarid region of the State of Pernambuco, Brazil, considering the calibration and validation of the model from streamflow and soil moisture data. Moreover, the study investigated hydrological effectiveness in a recovery scenario in areas of higher topographic elevation of the arborescent Caatinga and the behavior of the hydrological components under an agricultural expansion scenario. Events which occured between 2009 and 2010 were used to calibrate and validate streamflow and soil moisture data. The calibration and validation of streamflow exhibited efficiency coefficients (NSE) of 0.58 and 0.42, respectively, and 0.53 and 0.46 for soil moisture. The adjustment of the parameters was considered adequate for representing streamflow recession periods. It was also verified that the alternative process of calibration and validation with soil moisture reduced uncertainty. Regeneration of the vegetative cover over 21% of the hilltop areas of arborescent Caatinga led to a significant increase in percolation (42%) and a decrease of 34% in soil moisture (due to water consumption by plants), thus contributing to the recovery of headwaters, increasing resilience to water scarcity. On the other hand, the 38% expansion of agriculture caused an increase of 11% in surface runoff and, consequently, an increase of 10% in soil moisture.
A coupled model of hydrodynamics circulation and water quality applied to the Rio Verde reservoir, Brazil
Authors: Cunha Cynara De Lourdes da Nobrega , Corrêa Gabriela Pacheco , Rosman Paulo Cesar Colonna
Published: October 2018

This work applied the coupled horizontal two-dimensional hydrodynamic circulation model (2DH) and the vertically integrated water quality model for non-conservative and passive scalars to the Rio Verde reservoir in the state of Paraná, Brazil, to simulate flow, temperature and water quality parameters. The water quality model uses the same spatial grid applied for the hydrodynamics model. Flow velocities and turbulence coefficients previously defined in the hydrodynamics model can be used directly in the water quality model. Modeling results were compared to field data for a period of 308 days, from February 27th 2010 and December 31th 2010. Field data included water and air temperature, wind, relative humidity, radiation, discharges and concentration values of some substances in the tributaries of the reservoir. The results indicated that hydrodynamic circulation and, consequently, horizontal transport, are strongly dependent on the wind. Inflows/outflows generated a localized circulation. The results for the temperature and dissolved oxygen concentration were compared with field measures and a satisfactory consistency was achieved. Despite the errors associated with boundary conditions, the models demonstrated their potential to adequately simulate the data set collected from the reservoir.

Turaev–Viro invariants, colored Jones polynomials, and volume
Authors: Detcherry Renaud , Kalfagianni Efstratia , Yang Tian
Published: October 2018

We obtain a formula for the Turaev–Viro invariants of a link complement in terms of values of the colored Jones polynomials of the link. As an application, we give the first examples of 3-manifolds where the “large

r

” asymptotics of the Turaev–Viro invariants determine the hyperbolic volume. We verify the volume conjecture of Chen and the third named author [7] for the figure-eight knot and the Borromean rings. Our calculations also exhibit new phenomena of asymptotic behavior of values of the colored Jones polynomials that seem to be predicted neither by the Kashaev-Murakami-Murakami volume conjecture and its generalizations nor by Zagier’s quantum modularity conjecture. We conjecture that the asymptotics of the Turaev–Viro invariants of any link complement determine the simplicial volume of the link, and verify this conjecture for all knots with zero simplicial volume. Finally, we observe that our simplicial volume conjecture is compatible with connected summations and split unions of links.
Classical Authors on the Bookshelves of Carniolan Nobility
Authors: Dular Anja
Published: October 2018

Works by classical authors had a significant share in the aristocratic libraries of the Slovenian lands. While the selection of authors varied, there were some mainstays: Cicero, Horace, Ovid, Homer. The language of the books was either original or a German or French translation. All publications were furnished with commentaries and introductory chapters containing the authors’ biographies, often even with glossaries and grammar exercises. These additions, however, were considerably reduced in the 19th century. All library owners preserved classical language textbooks as well.
La influencia de Leberecht Migge en la creación de las Siedlungen productivas modernas
Authors: Arredondo Garrido David
Published: October 2018

Agriculture and food production has not been a central issue in the discourse of contemporary architecture and urbanism. In spite of this, it is possible to recover some interesting projects of architects who made serious efforts to reverse the disconnection between rural and urban worlds. Professionals who looked for a direct relationship between house functionality and food production. Some periods of crisis, like the interwar period in Central Europe, created an ideal atmosphere for the appearance of proposals that sought the food self-sufficiency of its inhabitants. This article aims to contextualize the role of the landscape architect Leberecht Migge and his connections with some architects in the creation of the modern Siedlungen. Migge's labor was eclipsed by the great masters of the Modern Movement with whom he worked, but he played a key role in the success of productive housing. His theoretical work and his designs stand out as the most effective and relevant modern Siedlungen where agriculture is fully integrated with housing. This trend ran parallel to the most groundbreaking proposals of the Modern Movement, but only for an ephemeral journey. Once the crisis that allowed its flowering was overcome, these same architects forgot self-sufficiency forever as an objective of their interventions.

Objetivo: Analisar o consumo de alimentos ultraprocessados entre crianças com transtorno do espectro do autismo (TEA) e sua associação com o estado nutricional. Métodos: Realizou-se um estudo transversal, em São Luís, Maranhão, Brasil, com amostra de 29 crianças, em 2017. Utilizou-se um questionário semiestruturado, aplicado aos pais ou responsáveis, para obtenção de variáveis sociodemográficas. O estado nutricional foi avaliado pelos indicadores de índice de massa corporal/idade e estatura/idade. Obteve-se o consumo alimentar por meio de recordatório de 24h, a partir do qual foi calculado o percentual de contribuição calórica e a média dos alimentos consumidos de acordo com o nível de processamento. Para comparação do consumo dos ultraprocessados de acordo com o estado nutricional, utilizou-se o teste t de Student, com nível de significância de 5%. Resultados: Verificou-se o excesso de peso em 55,2% (n=16) das crianças e o consumo de alimentos ultraprocessados foi responsável por 28% (560 kcal/dia) da contribuição calórica. Crianças com excesso de peso consumiram maior média percentual de alimentos ultraprocessados do que as sem excesso de peso (34,2% versus 19,4%, p=0,009). O consumo de frutas representou apenas 4,3% (74,6 kcal) da contribuição calórica total, e as hortaliças foram os alimentos in natura menos consumidos pelas crianças. Conclusão: Alimentos in natura ou minimamente processados foram a base da alimentação das crianças estudadas. Apesar disso, o maior consumo de alimentos ultraprocessados foi associado ao excesso de peso nas crianças com TEA.

Who Cares for Total Hip Arthroplasty Complications? Rates of Readmission to a Hospital Different From the Location of the Index Procedure
Authors: Chen James B. , Hegde Vishal , Cheung Edward C. , Stavrakis Alexandra I. , SooHoo Nelson F.
Published: October 2018

Introduction:

While the number of total hip arthroplasties (THAs) performed increases, so is the number of postoperative readmissions, resulting in costly episodes of care that may disproportionately affect certain hospitals. This study examines the rates of readmission of patients to the same hospital at which they underwent index THA, compared with readmission to a different hospital.

Methods:

Data for all hospital discharges from 1995 to 2010 were obtained from the California Office of Statewide Health Planning and Development database. Patient outcomes, readmission data, demographic information, hospital teaching status, and location were analyzed. Regression modeling was used to evaluate the effect of hospital teaching status, location, and individual complications on the risk of readmission to the same hospital as opposed to a different hospital following the index procedure.

Results:

The overall postoperative readmission rate for specific defined complications or all-cause 30-day readmissions was 3.92%, with 75.17% readmitted to the same hospital. Following index THA at a nonacademic or academic hospital, 95.9% and 84.6% of patients were readmitted to the same type of hospital, respectively. Patients who had their index procedure at an academic hospital had lower odds for readmission to the same hospital (odds ratio, 0.734; P < 0.0001) compared with nonacademic centers. Hospitals in midsize towns had higher odds of readmission to the same hospital (odds ratio, 1.735; P = 0.0012) compared with those in large metropolitan areas.

Discussion:

Although more than 75% of patients with unplanned readmissions went to the same hospital as their index THA, academic and larger metropolitan hospitals had higher odds of postoperative readmissions to a different hospital.

Published: October 2018

Topic modeling is a powerful technique for unsupervised analysis of large document collections. Topic models have a wide range of applications including tag recommendation, text categorization, keyword extraction and similarity search in the text mining, information retrieval and statistical language modeling. The research on topic modeling is gaining popularity day by day. There are various efficient topic modeling techniques available for the English language as it is one of the most spoken languages in the whole world but not for the other spoken languages. Bangla being the seventh most spoken native language in the world by population, it needs automation in different aspects. This paper deals with finding the core topics of Bangla news corpus and classifying news with similarity measures. The document models are built using LDA (Latent Dirichlet Allocation) with bigram.

A Conceptual Framework for Determinants of E-Exporting (Marketing Applications) Practices and the Business Performance: Empirical Study
Authors: Al-Dmour Hani Hamed
Published: October 2018

This research aims at identifying the determinants of the adoption of e-exporting marketing applications by Jordanian companies and their influence on their exporting performance. For this purpose, a conceptual framework based on the analysis of the literature review and the theoretical adoption models was developed. The required data was gathered through self-administrated questionnaire from 163 exporting industrial companies. The results showed that the extent of e-exporting applications being practiced is considered to be satisfactory (i.e. 62%) and they were varied among exporting companies in terms of their size and experience. The results of factor analysis (FA) indicated that 30 determinants variables could be grouped into three major factors: organizational, environmental and technological and they could explain 76% of the variation of e-exporting applications being implemented and 83% the variation on exporting performance. Furthermore, the results have shown that organizational factor was the most important one determining the extent e-exporting applications being implemented and the environmental factor was the most important one determining the exporting performance. These resultsprovide empirical evidence that the integration approach of the adoption model could produce better explanation of the variation on both the level of e-exporting applications being practised and the business performance. In the final section, research implications and future directions are presented.

Published: October 2018

Introduction: Particulate matter air pollution constitutes an important factor affecting the course of various respiratory and cardiovascular diseases. Two main monitored groups of particulate pollution are particulate matter with the aerodynamic diameter below 10 μm (PM10) and 2.5 μm (PM2.5). One of the most important respiratory diseases is chronic obstructive pulmonary disease (COPD). Clinical presentation of COPD and cardiovascular diseases is similar and can cause complications during therapy. The study explores connection between particulate matter and COPD exacerbations in population with cardiovascular cause of symptoms excluded. Material and methods: Analysis was based on data from hospitalisations in the years 2006–2016 in the hospitals of Upper Silesian Agglomeration, Poland. The data were correlated with meteorological conditions and particulate matter concentrations up to 90 days before hospital admission. Results: During the whole observation period no connection between PM10 concentration changes and COPD exacerbations were observed. On the other hand PM 2.5 influence started to be significant on 14 day before admission (RR 1.06) and increased up to maximal analysed period of 90 days (RR 1.32). Conclusions: Overall this study highlights the importance of particulate matter pollution emission impact on COPD exacerbations in a long time perspective.

Published: October 2018

The development of the different technologies included in the Industry 4.0 paradigm opens the door to an intensive monitoring of machine-tools. A data acquisition platform for both 2D and 3D analysis of machine performance under real factory conditions is presented in this study. The platform is composed of: 1) a data acquisition system that processes the information collected from the control memory and any other sensor integrated in the machine; 2) a remote server that stores the collected data; and, 3) a set of 2D and 3D interfaces both of which permit real-time calculation of KPIs and analysis of a specific machining process in a 3D virtual environment using Oculus Rift and Oculus Touch to detect anomalies in the machining process. This platform has been validated in a gantry milling machine machining large casting components. The results of this study demonstrate the detection of three types of anomalies in the machining process and the extent to which the immersive 3D environment makes it easier for the process engineer, especially in the case of junior process engineers, to detect them.

Published: October 2018

The production of plastic materials in 2016 was approximately 280 million tons, of which about 75% were disposed of in landfills. The constant accumulation of this type of waste has caused negative impacts on flora and fauna due to its low biodegradability. As an alternative to this complex problem, this work proposes the formulation of biopolymer mixtures based on polylactic acid (PLA) and native starch, as a viable option to minimize the impact caused by conventional plastics.

Software complexity metrics, such as code size and cyclomatic complexity, have been used in the software engineering community for predicting quality metrics such as maintainability, bug proneness and robustness. However, not many studies have addressed the relationship between complexity metrics and software testing and there is little experimental evidence to support the use of these code metrics in the estimation of test effort. We have investigated and evaluated the relationship between test effort (i.e, number of test cases and test execution time) and software complexity metrics for industrial control software used in an embedded system. We show how to measure different software complexity metrics such as number of elements, cyclomatic complexity, and information flow for a popular programming language named FBD used in the safety critical domain. In addition, we use test data and test suites created by experienced test engineers working at Bombardier Transportation Sweden AB to evaluate the correlation between several complexity measures and the testing effort. We found that there is a moderate correlation between software complexity metrics and test effort. In addition, the results show that the software size (i.e., number of elements in the FBD program) provides the highest correlation level with the number of test cases created and test execution time. Our results suggest that software size and structure metrics, while useful for identifying parts of the system that are more complicated, should not be solely used for identifying parts of the system for which test engineers might need to create more test cases. A potential explanation of this result concerns the nature of testing, since other attributes such as the level of thorough testing required and the size of the specifications can influence the creation of test cases. In addition, we used a linear regression model to estimate the test effort using the software complexity measurement results.

This paper is the last of a three-part series that investigates the architecture of cancellous bone in the main hindlimb bones of theropod dinosaurs, and uses cancellous bone architectural patterns to infer locomotor biomechanics in extinct non-avian species. Cancellous bone is highly sensitive to its prevailing mechanical environment, and may therefore help further understanding of locomotor biomechanics in extinct tetrapod vertebrates such as dinosaurs. Here in Part III, the biomechanical modelling approach derived previously was applied to two species of extinct, non-avian theropods,Daspletosaurus torosusandTroodon formosus. Observed cancellous bone architectural patterns were linked with quasi-static, three-dimensional musculoskeletal and finite element models of the hindlimb of both species, and used to derive characteristic postures that best aligned continuum-level principal stresses with cancellous bone fabric. The posture identified forDaspletosauruswas largely upright, with a subvertical femoral orientation, whilst that identified forTroodonwas more crouched, but not to the degree observed in extant birds. In addition to providing new insight on posture and limb articulation, this study also tested previous hypotheses of limb bone loading mechanics and muscular control strategies in non-avian theropods, and how these aspects evolved on the line to birds. The results support the hypothesis that an upright femoral posture is correlated with bending-dominant bone loading and abduction-based muscular support of the hip, whereas a crouched femoral posture is correlated with torsion-dominant bone loading and long-axis rotation-based muscular support. Moreover, the results of this study also support the inference that hindlimb posture, bone loading mechanics and muscular support strategies evolved in a gradual fashion along the line to extant birds.

Subterranean rodents are able to dig long straight tunnels. Keeping the course of such “runways” is important in the context of optimal foraging strategies and natal or mating dispersal. These tunnels are built in the course of a long time, and in social species, by several animals. Although the ability to keep the course of digging has already been described in the 1950s, its proximate mechanism could still not be satisfactorily explained. Here, we analyzed the directional orientation of 68 burrow systems in five subterranean rodent species (Fukomys anselli,F. mechowii,Heliophobius argenteocinereus,Spalax galili, andCtenomys talarum) on the base of detailed maps of burrow systems charted within the framework of other studies and provided to us. The directional orientation of the vast majority of all evaluated burrow systems on the individual level (94%) showed a significant deviation from a random distribution. The second order statistics (averaging mean vectors of all the studied burrow systems of a respective species) revealed significant deviations from random distribution with a prevalence of north–south (H. argenteocinereus), NNW–SSE (C. talarum), and NE–SW (Fukomysmole-rats) oriented tunnels. Burrow systems ofS. galiliwere randomly oriented. We suggest that the Earth’s magnetic field acts as a common heading indicator, facilitating to keep the course of digging. This study provides a field test and further evidence for magnetoreception and its biological meaning in subterranean mammals. Furthermore, it lays the foundation for future field experiments.
Uncovering hidden specific diversity of Andean glassfrogs of theCentrolene buckleyispecies complex (Anura: Centrolenidae)

Published: October 2018

The glassfrogCentrolene buckleyihas been recognized as a species complex. Herein, using coalescence-based species delimitation methods, we evaluate the specific diversity within this taxon. Four coalescence approaches (generalized mixed Yule coalescents, Bayesian general mixed Yule-coalescent, Poisson tree processes, and Bayesian Poisson tree processes) were consistent with the delimitation results, identifying four lineages within what is currently recognized asC. buckleyi. We propose three new candidate species that should be tested with nuclear markers, morphological, and behavioral data. In the meantime, for conservation purposes, candidate species should be considered evolutionary significant units, in light of observed population crashes in theC. buckleyispecies complex. Finally, our results support the validity ofC. venezuelense, formerly considered as a subspecies ofC. buckleyi.

Most valuable cured products from Iberian pigs come from pure bred animals raised for a final grazing-fattening period where pigs eat mainly acorns, a low protein energy rich fruit. This is a nutritional challenge for animals fed equilibrated diets from weaning. The aim of the study was to determine net portal appearance (NPA) of metabolites in gilts fed acorns and evaluate adaptational changes after one week of feeding. Two sampling periods were carried out (after one day and after one week of acorn feeding) with six gilts (34 kg average BW) set up with three catheters: in carotid artery and portal vein for blood sampling, and ileal vein for para-aminohippuric acid (PAH) infusion to measure portal plasma flow (PPF). Pigs were fed at 2.5 × ME for maintenance a standard diet in two portions, at 09:00 (0.25) and 15:00 h (the remaining 0.75). On the day prior to the first sampling period, pigs were fed 2.4 kg of oak acorns. After feeding 0.25 of ration a 6 h serial blood collection was initiated. Following an identical protocol, a second sampling session was performed 1 week later. Adaptation to acorn consumption decreased NPA of ammonia (47%,P < 0.001). Although there was a transfer of urea from the gastrointestinal tract to the circulation in both sampling periods, no differences in NPA of urea was found (P > 0.05). NPA of glucose was not influenced by sampling period (P > 0.05), but NPA of lactate was greatly increased (231%,P < 0.001). There was a negative NPA of albumin although adaptation to acorn feeding did not alter it. Although NPA of triglycerides and cholesterol were unchanged, a subtle increase in arterial and portal cholesterol was noticed (9.6%,P < 0.01). Pigs fed a protein deficient diet for one week adapted decreasing NPA of ammonia for saving metabolic energy as less ammonia would become available for conversion to urea.

The surface tension and the viscosity of the alloys Ti48Al48Nb2Cr2, Ti46Al46Nb8, and Ti46Al46Ta8 are measured with the oscillating drop technique in an electromagnetic levitation device under reduced gravity conditions on board a parabolic flight airplane. The surface tensions as a function of temperature are obtained as σ(T) = (1.19 ± 0.02 − 3.80 × 10−4 (T − 1856 K)) Nm−1 for Ti46Al46Nb8, σ(T) = (1.21 ± 0.02 − 2.69 × 10−4 (T − 1879 K)) Nm−1 for Ti46Al46Ta8, and σ(T) = (1.20 ± 0.02 − 3.96 × 10−4 (T − 1776 K)) Nm−1 for Ti48Al48Nb2Cr2, concentrations in atomic per cent. The viscosities at the liquidus temperatures are obtained as η(Tl) = 6.62 mPa.s, η(Tl) = 6.9 mPa.s, and η(Tl) = 5.8 mPa.s in the same order. All processed specimens are solidified at an undercooling of ΔTu = 220 ± 30 K. In addition, the solidus and liquidus temperatures and the enthalpies of fusion are determined by calorimetry. From the large undercooling and the enthalpy of fusion, the average specific heat capacity at an undercooling of 120 K is obtained as cP(av) = 1.30 ± 0.20 J (kg)−1 for all alloys. The thermal expansion between the room and solidus temperatures is measured by dilatometry.
