An updated review of the evidence for adjustable compression wrap devices in the lower limb
Authors: Williams Anne
Published: March 2018

Compression therapy is a key component in the effective management of people with lower limb problems associated with venous, lymphatic and fat disorders such as lipoedema. Individuals with lymphoedema, venous ulceration and lipoedema often require long-term compression therapy to prevent and manage problems such as chronic ulceration and skin changes, persistent swelling and shape distortion. There are challenges in achieving acceptable, safe, effective and cost-efficient compression therapy choices. Adjustable, compression-wrap devices incorporating hook-and-loop systems present new opportunities for improving treatment outcomes, supporting patient independence and self-management in the use of compression therapy.

Intraspinal schwannoma and neurogenic bladder
Authors: Yang KS , Ho CS , Tai PA , Kung WM
Published: March 2018

Most lumbar intradural schwannomas present initially as radiculopathies with sensory disturbances. However, neurogenic bladder dysfunction may be one of the earliest manifestations and can cause long-term disability. We present the case of a patient with a L3–4 schwannoma (newly diagnosed owing to recurrent urinary retention and urinary tract infection) who finally underwent surgical resection. Improvement of bladder sensation was documented by urodynamic study and the patient was subsequently weaned off her Foley catheter with satisfactory outcome.
Management of Paediatric Testicular Torsion – Are we adhering to Royal College of Surgeons (RCS) recommendations
Authors: Thakkar HS , Yardley I , Kufeji D
Published: March 2018

Introduction

In 2015, the Royal College of Surgeons of England (RCS) commissioned the East Midlands Clinical Network to develop a set of guidelines for the management of paediatric torsion. Two quality measures identified were the provision of surgery locally where possible and 100% of explorations within three hours. We sought to assess the adherence to these quality measures within our referral network.

Materials and methods

Retrospective data were collected for all paediatric scrotal explorations performed within our centre between January 2014 and July 2016. Patient demographics, sources of referral, transfer times, time to surgery and operative findings were obtained.

Results

A total of 100 patients underwent a scrotal exploration. Median age at presentation was 11 years (range 4 months to 15 years). Fifty-three per cent of referrals were from network hospitals. The median duration of symptoms was 25 hours (range 1–210 hours). The median transfer time from local centres was 120 minutes (range 45–540 minutes). The median time to theatre from the decision being made to operate was 60 minutes (range 30–600 minutes). Eighty-seven per cent of cases were explored within three hours. There were 13 cases of torsion with one orchidectomy. When taking into account the transfer time for external patients aged over five years without precluding comorbidities, exploration within three hours dropped to 18 of 46 (39%).

Conclusion

The RCS guidelines recognise the need for specialist input in very young patients. A large proportion of explorations are, however, currently taking place in older patients with unacceptably long transfer times. We propose an extension of this review nationally to work towards the local provision of care for suitable patients.
A case report of an angiomyxoma in the liver
Authors: Malik AK , Filobbos R , Manoharan A , Harvey N , O’Reilly DA , de Liguori Carino N
Published: March 2018

Angiomyxomas are uncommon myxoid tumours arising most commonly from the pelvis. A 46-year-old woman with a history of polycystic kidney disease presented asymptomatically for surveillance ultrasonography; changes were noted in the size and morphology of her liver cysts. Subsequent radiological assessment displayed features suspicious of malignancy and a right hemihepatectomy was performed with curative intent. Pathological examination of the resected specimen found histology consistent with an angiomyxoma arising primarily from the liver parenchyma. Follow-up review of the patient has been uneventful with annual imaging showing no evidence of recurrence. Angiomyxomas do not characteristically invade other tissues. However, any liver lesion displaying suspicious features of malignancy should be resected in the absence of disseminated disease.
O PEPP e os estudos sobre o português de Salvador
Authors: Lopes Norma Da Silva
Published: March 2018

Este artigo trata do acervo de fala intitulado Programa de Estudos sobre o Português Popular de Salvador, o PEPP (LOPES; SOUZA; SOUZA, 2009), muito utilizado por pesquisadores baianos, para o estudo do português de Salvador. O referido acervo foi constituído de início para servir de corpus para três teses de doutorado, na época em realização na Universidade Federal da Bahia. O PEPP se guiou pelas orientações de entrevista sociolinguística (LABOV, 2008[1972]). Esse texto objetiva, primeiramente, (1) apresentar os fundamentos teóricos do acervo PEPP já constituído, o PEPP 1; (2) caracterizar o PEPP 1, seus objetivos e pesquisadores responsáveis; (3) expor dados sobre sua composição: número de faixas etárias, escolaridades e gêneros, metodologia das entrevistas, etc; (4) listar alguns estudos com base nos dados do PEPP e (5) discutir a importância e representativa do PEPP no contexto dos estudos sociolinguísticos na Bahia. No presente momento, o PEPP 2 está em fase de planejamento, duas décadas depois, buscando colocar à disposição um novo acervo que dê margem a estudos em duas sincronias em análises sociolinguísticas diversas. Além da caracterização do PEPP 1, este artigo pretende apresentar o que se planeja como PEPP 2 e como esse acervo deve se caracterizar. Dessa forma, este texto objetiva colocar a proposta do PEPP 2 em discussão/apreciação pela comunidade científica da área, para possibilitar sugestões para que o PEPP possa dar sua contribuição para os estudos atuais sobre o português brasileiro.
A influência da escolaridade no processo de variação de concordância verbal na língua usada em Serra Talhada
Authors: Da Silva Juliana , Santos Renata Lívia de Araújo
Published: March 2018

O presente artigo tem o propósito de analisar a influência da variável extralinguística escolaridade no processo de variação de concordância verbal na língua usada no sertão pernambucano. Nossa fundamentação teórica- metodológica segue os pressupostos da Sociolinguística Variacionista de Labov (2008[1972]). Os estudos variacionistas sobre a concordância verbal no português brasileiro apontam que esse fenômeno é altamente variável, e condicionado pela influência de fatores linguísticos e sociais. Neste trabalho, estamos considerando os seguintes níveis de escolaridade: o ensino fundamental, o ensino médio e o ensino superior, para que possamos verificar quais destes níveis de escolarização propiciam um favorecimento na marcação da regra de concordância verbal. Os resultados alcançados apontam um favorecimento na marcação de CV no falar serra-talhadense, sendo que a variável social escolaridade foi apontada como a segunda variável mais significativa para o nosso estudo.
Funções discursivas dos marcadores olhe, olha e repare na fala sergipana
Authors: Santana Rebeca Rodrigues de
Published: March 2018

Os marcadores discursivos são itens que exercem um importante papel comunicativo, articulando simultaneamente valores distintos: de caráter textual, ao estabelecer ligações coesivas entre partes do texto e de caráter interpessoal, ao manter a interação entre os interlocutores e auxiliar no planejamento da fala (MARCUSCHI, 1989). O presente trabalho tem como objetivo geral descrever as funções dos marcadores discursivos olhe, olha, veja e repare em um corpus sergipano, e como objetivos específicos: identificar todas as ocorrências dos referidos marcadores na amostra Redes Sociais de Informantes Universitários de Itabaiana/SE (ARAÚJO; SANTOS; FREITAG, 2014); analisar tais ocorrências quanto às funções desempenhadas, e contribuir com a descrição e sistematização de tal categoria. Para tanto, selecionou-se 24 interações conduzidas da amostra Redes Sociais de Informantes Universitários de Itabaiana/SE (ARAÚJO; SANTOS; FREITAG, 2014), pertencente ao Banco de Dados Falares Sergipanos (FREITAG, 2013, 2017). Selecionadas as interações, realizou-se a extração de todas as ocorrências dos marcadores propostos para análise. Em seguida, tais ocorrências foram analisadas quanto ao seu valor funcional nos contextos empregados, sendo as ocorrências de olhe e olha também ouvidas para constatar usos vocalizados (ói e óia). Por fim, os dados obtidos foram submetidos à análise estatística descritiva. Os resultados alcançados nesse estudo podem contribuir com os trabalhos descritivos de marcadores discursivos, mais especificamente de chamada de atenção do ouvinte, e também com estudos acerca da fala sergipana, uma vez que o corpus utilizado é uma amostra de fala de uma comunidade universitária do estado de Sergipe.
Embryogenesis and Applications of Fingerprints- a review
Authors: LH Adamu , MG Taura
Published: March 2018

Fingerprint is an impression made by the friction ridges that are almost parallel at constant crest to crest wavelength. The pattern is dominated by central features, such as whorls, loops, arches and triradii. Fingerprints have been used for several decades in forensic and medical sciences. The fingerprints characteristics such uniqueness, consistency and universality are the main features that are used by forensic experts in identification processes, are well developed during intra-uterine life. Understanding embryogenesis of fingerprints is essential in linking its features to some disease conditions. The purpose of this review was to highlight information regarding establishment, formation, hypotheses and factors affecting fingerprints. Applications of the fingerprints in forensic and medical sciences were also highlighted. Both environmental (in utero) and genetic factors have role to play in the formation of the fingerprints. The primary role of fingerprints is personal identification; these can be achieved through revealing sex, ethnicity, diet and lifestyle of an individual. In another perspective the fingerprints can be used as tools in diagnosis and ascertaining presence of disease conditions, however, this is population specific.

Community management et métiers émergents du numérique
Authors: Larroche Valérie
Published: March 2018

Cet article approfondit les représentations des métiers émergents du numérique par les employeurs annonceurs et les recruteurs d’agence de recrutement. En comparant 12 fiches métiers de différents référentiels en communication marketing publiés entre 2009 et 2015, on constate des stratégies de visibilité qui minimisent les relations permettant la reconnaissance mutuelle d’individus singuliers. Un focus sur le métier de community manager permet d’une part d’observer l’évolution des représentations de ce métier par les recruteurs, et d’autre part d’analyser les relations établies entre le community management et les métiers émergents étudiés. Les référentiels dans cet article sont le matériel de base des analyses. Ils sont considérés comme des dispositifs de confiance (Karpik, 2007) et des outils de traduction (Callon, 1986).
This article examines in depth employers’ and recruitment agencies’ representations of emerging digital professions. Comparing twelve different emerging job’s descriptions released in the 2009-2015 period, we put in evidence that visibility strategies are privileged over the mutual recognition between individuals. A focus on community manager allows us firstly, to observe how representations of recruiters are evolving and secondly, to explore relations mainly between community management and other emerging professions. Reference guides in this article are considered as confidence devices (Karpik, 2007) and non-human actors (Callon, 1986).
Pédagogie et dilemmes de l’enseignement de l’éthique du lobbying
Authors: Desmoulins Lucile
Published: March 2018

Si les relations théoriques et pratiques entre lobbying et éthique sont complexes à appréhender, leur enseignement relève de la gageure. Une méthodologie pluraliste d’enquête associant l’analyse de discours à l’ethnographie organisationnelle a permis de formuler une proposition conceptuelle sur la nature même du lobbying, et d’étudier l’impérieuse nécessité de la présence d’enseignements abordant l’éthique dans les formations en lobbying. Les étudiants expriment souvent des questionnements et un souci éthique. Pour autant, le statut de l’éthique dans les formations françaises de niveau Master paraît limité à la portion congrue dans leurs supports de communication. La pédagogie des relations entre lobbying et éthique est en tension entre le souhait de répondre aux attentes d’étudiants en demande de repères clairs tels que le cadre légal ou les normes sociales, et le devoir de réaffirmation de la subjectivité des valeurs et du caractère pragmatique des questionnements éthiques.
Mots-clés : lobbying, éthique, pédagogie, intelligence économique, professionnalisation. 
 
Since the theoretical and practical relations between lobbying and ethics are complex to grasp, teaching ethical lobbying is a challenge. A pluralistic methodology led to explore the pedagogical practices and dilemmas met when teaching the ethics of lobbying. Based on a conceptual analysis of lobbying as a sector of activity and a set of practices and techniques aimed to influence political decision-making processes, ethics courses appeal to lobbying students. However, there are very few such courses in French Master level training programs, and the term itself appears seldom in their brochures and web-sites. Yet, students prove to be keen on asking questions and getting answers on that matter during all courses of such programs. The pedagogy of the relations between lobbying and ethics is complex because it should meet students’ expectations to learn the legal framework, the codes of conducts, as well as the do and the don’t that drive from social norms, whereas teachers should recall that values are subjective and that one should be pragmatic when one meets ethical dilemmas in his daily work.
Key words: lobbying, ethics, pedagogy, business intelligence, professionalization.

Pocos han sido los ingleses que se han interesado en la historia de Colombia, contados quienes se han interesado en su fotografía. Una de las pocas excepciones ha sido el historiador Malcom Deas, quien ha escrito y curado exposiciones donde ambas se unen. Su exposición Historia de Colombia a través de su fotografía 1842-2010 (2011), fue un sobrio y personal intento por parte de unos de los colombianistas más queridos en el país, por interpretar visualmente una esencia de esta nación. Es a la vez un ejemplo y un estímulo —deseablemente— para que los historiadores que trabajan sobre este país, se animen a realizar curadurías e investigaciones visuales y acerquen y se acerquen, por medio de ellas, al gran público.
Índice de potencialidade socioeconômica, produtiva e ambiental de comunidades pesqueiras situadas no norte do Estado do Espírito Santo (IPSPA - Norte)
Authors: Gomes Vanielle Aparecida do Patrocinio , Freitas Rodrigo Randow de
Published: March 2018

A atividade pesqueira tem crescido nas últimas décadas, sendo que no estado do Espírito Santo a pesca artesanal se destaca. Mesmo com a geração de empregos, renda e alimentos são identificados pontos negativos como a degradação do meio ambiente, sobre-exploração, redução dos estoques marinhos e estuarinos, e ainda a alta taxa de analfabetismo dos pescadores. Este estudo vem identificar as potencialidades e vulnerabilidades da atividade na região norte do estado do Espírito Santo, comparando os munícipios costeiros que o compõe, sendo eles Conceição da Barra, São Mateus e Linhares. Para isso, utilizou-se o Método Analytic Hierarchy Process (AHP) para hierarquizar tais municípios quanto ao potencial desenvolvimento e a assim, foi realizada a análise do ambiente com a utilização de uma matriz para análise de cenários (SWOT). Os resultados apontaram que devido a importância que os entrevistados deram ao subíndice produtivo, o município de Conceição da Barra sobressaiu-se à ordem prioritária do objetivo de definir o município no litoral norte do estado do Espírito Santo com maior Índice de Potencialidade Socioeconômica, Produtiva e Ambiental na atividade pesqueira, por apresentar dados quantitativos relacionados a esse subíndice superiores aos demais municípios. No entanto, quando realizada a análise para cada subíndice separadamente, Conceição da Barra aparece em última colocação, apresentando-se vulnerável às questões Ambientais, Sociais e Econômicas.
Aplicação da teoria das opções reais para avaliação de política pública: a política inovar-auto no setor automotivo brasileiro
Authors: Oliveira Francisco Alexandre de
Published: March 2018

A indústria automobilística tem uma importância crescente no contexto econômico brasileiro. O setor movimenta uma cadeia enorme que engloba fabricantes e fornecedores, postos de gasolina, seguradoras, oficinas mecânicas, borracharias, empresas de comunicação, agências de publicidade, entre outros. Consciente desta importância, o governo federal, através da Lei n° 12.715 de 17 de dezembro de 2012, instituiu o Programa de Incentivo à Inovação Tecnológica e Adensamento da Cadeia Produtiva de Veículos Automotores - INOVAR-AUTO com o objetivo de apoiar o desenvolvimento tecnológico, a inovação, a segurança, a proteção ao meio ambiente, a eficiência energética e a qualidade dos automóveis, caminhões, ônibus e autopeças. No entanto, as empresas adotam tais políticas públicas quando é possível avaliar os ganhos obtidos com sua implantação. Deste modo, esta pesquisa apresenta a aplicação da Teoria das Opções Reais (TOR) na avaliação da política pública de Incentivo à Inovação Tecnológica e Adensamento da Cadeia Produtiva de Veículos Automotores. A abordagem modela a tomada de decisão como uma opção de compra americana em um projeto de instalação de uma unidade produtora de veículos automotores que deseja aderir ao INOVAR-AUTO. Os resultados apontam que não é interessante para a empresa adotar tal política, para o prazo estipulado de cinco anos.

Site response analysis for dynamic soil–structure interaction and performance-based design
Authors: O'Riordan Nick J. , Almufti Ibrahim , Lee Jongwon , Ellison Kirk , Motamed Ramin
Published: March 2018

The increasing power of four-dimensional analysis tools and advanced soil models has facilitated performance-based design processes to be followed for foundations in highly seismic areas. Often more efficient foundation solutions result than would be achieved by direct application of codes. Particular care is required in the selection and scaling of input ground motions, applied at an appropriate depth below the foundation system, with properly characterised soil properties and defined hazard level. A performance-based design process that has been applied successfully on many projects is described and is applied to two contrasting situations: a near-fault site in San Francisco where pulse-like ground motions are explicitly considered in seismic hazard assessment and a very soft soil site in Mexico City where amplification and strength mobilisation effects dominate. Outcomes from the analysed examples are examined and compared with the very limited code-based guidance that exists currently for performance-based design of foundations.

Türkiye inşaat
sektörünün ekonomik, çevresel, ve sosyal etkilerinin analizi son yıllarda
önemini giderek artırmıştır. Özellikle artan inşaat, ulaşım, üretim ve enerji
yatırımları Türkiye ve dünya ekonomisine doğrudan ve dolaylı etkiler
yapmaktadır. Bu makalede, Türkiye için önemli bir araştırma boşluğunu doldurmak
amacıyla Türkiye’deki inşaat sektörünün uluslararası tedarik zincirlerini de
kapsayacak bir biçimde ilk, web tabanlı ve küresel karbon ayakizi analizi
yapılmıştır. Avrupa Komisyonu 7. Çerçeve Araştırma Programınca desteklenen

Published: March 2018

The heterogeneous network (HetNets) emerge as one of
the most auspicious improvements toward realizing the objective specifications
of Long Term Evolution-Advanced (LTE-A) networks. Though, similar all other
wireless networks, HetNet also yield from the interference problems, i.e., the
co-tier and cross-tier interferences. Regarding
proper functionality and efficiency of the HetNets, the avoidance and
management of the said interferences are very crucial. In this study, a power
control algorithm is suggested to decrease the interferences disadvantages in
the HetNets. To calculate the signal power,
the SINR (Signal to Interference and Noise Ratio) and RSRP (Reference Signal
Received Power) are used for downlink and uplink respectively. The selection decision is taken by signal strength
information. The UE (User Equipment) is
switched accordingly. A simulation is used to investigate and find out
the nearest cell to UE in a HetNet.
Evaluation of the symmetric effect of antagonists in the floral morphs of the distylic shrub Bouvardia ternifolia: a field study
Authors: Salinas-Esquivel Luis Antonio , Lara Carlos , Arizmendi María del Coro
Published: March 2018

Background: Heterostyly is a genetic polymorphism characterized by a system of sporophyte auto-incompatibility in which the plant populations show two (distyly) or three (tristyly) floral morphs. This reproductive system is known as a promoter of cross-pollination, assuming similar reproductive success between morphs.Hyphothesis: For this assumption to take place, the pollinators must respond in a similar manner to attraction floral traits in both morphs, maintaining a symmetric flow of pollen. We hypothesize that floral damage by antagonists should correspond to similarities or differences in atractiveness among floral morphs.Studied species: We tested this hypothesis in the distylous shrub Bouvardia ternifolia (Rubiaceae).Methods: we evaluated the magnitude of the nectar theft, foliar herbivory, and seed predation by assessing individual plants of both floral morphs throughout their flowering period (June-July 2015) under natural conditions. At the end of the flowering season, we quantified fruit and seed production.Results: The intensity of the herbivore and nectar thieves in this distylous population is similar between morphs, as well as the size of their floral displays. The number of seeds and fruits produced was also similar between morphs.Conclusions: Our study showed that selection pressures imposed by antagonists were similar to both floral morphs in the studied population of Bouvardia ternifolia.
Morbidity and mortality pattern of very low birth weight infants admitted in SNCU in a South Asian tertiary care centre
Authors: S. Kabilan , Kumar Mekalai Suresh
Published: March 2018

Background: Around 4-8% of all live births are very low birth weight (VLBW) infants.  In India currently 8 million VLBW infants are born each year which constitutes 40% of global burden the highest for any country. The present study was done to determine frequency of disease, complications, survival rate and risk factors for morbidity and mortality in VLBW babies.Methods: Between October 2016 and September 2017, we did a cross-sectional retrospective study at level three SNCU with >98% inborn admissions and about more than 10000 deliveries per year. The American Academy of Pediatrics protocol for neonatal resuscitation was followed for the management of VLBW. Data were entered in predetermined proforma and statistical analysis was done.Results: There were 154 registered cases of VLBW [75 females (48.7%) and 79 males (51.3%)]. The mean birth weight=1.198 (SD=0.211). The mean gestational age in weeks was 31.9 (SD=3.095).  Majority of them were in the gestational age 33-36 weeks (n=68, 44.2%), small for gestational age (n=89, 57.8), delivered through normal vaginal delivery (n=95, 61.7%), singletons (n=126, 81.8%), inborn (n=152, 98.7%), maternal age between 21-30 (n=95, 61.6%), clear amniotic fluid (n=137, 89%), on antenatal steroids (n=59, 38.3%), maternal disease were present in 55 mothers (33%) and gestational hypertension being more common (n=14, 9.6%). Majority of babies had Respiratory Distress Syndrome (n=56, 33.6%), birth asphyxia (n=54 32.4%) and sepsis (n=46, 27.6%). Mortality of 40.3% (n=62) observed in present study. Forty three babies with RDS, twenty babies with asphyxia and eight babies with sepsis expired.Conclusions: Multiple regression analysis with adjusted estimates of odds ratio showed that very low birth weight, low Apgar score at 5 minute, intubation and mechanical ventilation were predictors of outcome of VLBW babies. Birth weight and mechanical ventilation were significant predictors of the outcome of ELBW babies.

Background: Distal end radius fractures are the most common fractures seen among all orthopaedic injuries, accounts for nearly 20% of all fractures coming to the emergency department.There are various treatment modalities for distal end radius fracture which includes closed reduction and casting, closed reduction with external fixation and closed reduction with internal fixation.

Methods: This retrospective study was done on patients who underwent distal end radius fracture surgery in the Department of Orthopaedics at MGM Hospital Kamothe in the last 2 years from May 2015 to May 2017. Total of 108 patients were included in the study, out of which 62 were males and 46 were females undergoing distal end radius fracture surgery. The mean age was 34.5 (28-75 years age group). All patients were assessed with wrist radiograph to see the collapse post-operatively and after 4-6 weeks.

Results: The mean age was 34.5 (28-75 years age group). Out of 108, three females treated with cast lost for follow up. Out of all three modalities we took under study, we found that the average radial height in cast was 15 mm, in k wire was 10.5 mm while in external fixator was 12.5 mm. The average articular step in cast was 1.3 mm, in k wire was 2.1 mm while in external fixator was 1.8 mm. Fracture collapse was seen as 23.3% in cast, 21.4% in k-wire and 13.8% by external fixator.

Conclusions: Distal end radius fractures are most common fractures seen daily in both OPD and emergency. A basic idea about this fracture should be known general physicians also such as splinting as they also encountered with them routinely. External fixator is quite effective method of treatment for these fractures. In our study we have discussed closed reduction and fixation techniques and found better results with external fixator using principle of ligamentotaxis.
Fatores psicossociais de risco no trabalho e Transtorno Mental Comum: uma revisão sistemática de estudos que utilizaram os instrumentos JCQ, JSS e SRQ-20
Authors: Jacinto Aline , Tolfo Suzana Da Rosa
Published: March 2018

O objetivo deste estudo é analisar pesquisas empíricas que utilizaram o Job Content Questionnaire (JCQ) ou Job Stress Scale (JSS) e o Self-Reporting Questionnaire (SRQ-20), como instrumentos. O JCQ e JSS avaliam fatores psicossociais de trabalho favoráveis ou de risco, enquanto o SRQ realiza um rastreio da saúde mental do trabalhador. Os resultados demonstraram relações entre alta exigência e Transtorno Mental Comum (TMC), ou seja, trabalhadores aos quais percebem seu trabalho com alta demanda e baixo controle têm mais chances de apresentarem comprometimentos em sua saúde. Outro aspecto verificado foi a correlação entre alta exigência e baixo suporte social, assim trabalhadores que recebem pouco suporte social de supervisores e colegas de trabalho, possuem mais chances de perceber o trabalho com alta demanda e baixo controle. Verificou-se que as populações mais investigadas, com maiores fatores psicossociais de risco à saúde e com maiores prevalências TMC, foram docentes e profissionais da saúde. Esta pesquisa possibilitou-se analisar o quadro atual de produção de conhecimento sobre a temática, assim como, identificar o quanto os fatores psicossociais de risco no trabalho podem ter consequências prejudiciais na saúde dos trabalhadores.

The map of candidate genes that can potentially affect physical fitness becomes larger every year, and that are associated with such aspects as respiratory and cardiovascular stability; body build and composition – especially muscle mass and strength; carbohydrate and lipid metabolism; response to training; and exercise intolerance. The aim of this study was the analysis of the determination by CA repeat polymorphism of the P1 promoter of the IGF1 gene the structure of motor skills in the two groups of polish young athletes in 2011-2013.            In this study, 350 young sportsmen representing different sports disciplines were examined (age = 15.5 ± 0.5 years), by genotyping the IGF1 gene and determining the structure of motor skills using the International Physical Fitness Test (IPFT) battery. Analysis of the multiple stepwise regression, used to determine the impact of the investigated motor skills on the indicator of the overall physical fitness, measured by the total score of the International Physical Fitness Test (IPFT), shows some regularity related to the character of the IGF1 gene polymorphism. It can be concluded that in the case of two groups of young boys athletes practicing various sports disciplines (kinds of physical exercise) have similar associations between CA repeat polymorphism of the P1 promoter of the IGF1 gene and the level of motor effects. Our results suggest that this polymorphism may be a genetic marker of the physical performance phenotype. We demonstrated that CA repeat polymorphism of the P1 promoter of the IGF1 gene in the groups who were homozygous and noncarriers was associated with strength predispositions. In the group who were heterozygous speed-strength aptitudes
Considerations and Pitfalls in Selecting the Drug Vehicles for Evaluation of New Drug Candidates: Focus on in vivo Pharmaco-Toxicological Assays Based on the Rotarod Performance Test
Authors: Matias Mariana , Silvestre Samuel , Falcão Amílcar , Alves Gilberto
Published: March 2018

Purpose - During the discovery and development of new drugs, compounds with low aqueous solubility pose special challenges in their pharmacological evaluation and, therefore, the selection of appropriate vehicles to administer the compounds of interest is determinant for the quality of the results generated during the in vivo non-clinical studies. This work aimed to evaluate the motor deficit (as a surrogate of neurotoxicity) of several administration/delivery vehicles through the rotarod performance test. Methods - Trained male CD-1 mice were intraperitoneally administered with the following vehicles: dimethyl sulfoxide (DMSO), aqueous sodium chloride (NaCl) 0.9%, aqueous carboxymethylcellulose (CMC) 0.5%, polyethylene glycol (PEG)-400, propylene glycol (PG), and solutions of these vehicles containing 5% and 10% DMSO. Results - It was observed that the aqueous vehicles (NaCl 0.9% and CMC 0.5%) did not affect the performance of the animals on the rod. On the other hand, a vehicle consisting solely of DMSO led to significant motor impairment and only a small improvement was recorded over time. Additionally, a strong neuromotor toxicity was observed in the early evaluation points of the experiment using vehicles constituted by PG and PEG-400 or by mixtures of PG/DMSO (5% and 10%) and PEG-400/DMSO (5% and 10%). Conclusion - This study provides useful data about the neurotoxicity inherent to several vehicles frequently used in non-clinical pharmaco-toxicological assays, aiming to draw especial attention to the need of a careful selection of drug vehicles in order to avoid the impact of such confounding variables on the accuracy of the results and in decision-making processes. This article is open to POST-PUBLICATION REVIEW.

Autonomía y vulnerabilidad en la vejez: respuestas judiciales emblemáticas
Authors: Dabove María Isolina
Published: March 2018

En este trabajo se debate acerca de la autonomía de la voluntad de las personas mayores en situación de dependencia a la luz del derecho de la vejez. Para ello, se estudia el sistema de la autonomía compuesto por la capacidad, la voluntad, la curatela y los sistemas de apoyo, asistencia y representación del código civil y comercial argentino, vigente desde agosto de 2015. Se analizan sus precedentes jurisprudenciales principales y su alcance valorativo. Además, se considera su articulación respecto de la reciente Convención Interamericana sobre la Protección de los Derechos Humanos de las Personas Mayores (CIDHPM) de la OEA, vigente desde el 11 de enero de 2017.

Published: March 2018

La necesidad de extender cursos y carreras de nivel terciario al interior del país es una realidad inobjetable y advertida por todos. No obstante, pocos han sido los movimientos educativos tendientes a abordar esta problemática. La centralización de las actividades educativas terciarias en Montevideo hace que el interior del país esté vacío, en buena parte, de profesionales para dicho nivel. Esta innovación intenta aportar algunos elementos básicos a través de la implementación del dictado de un curso regular de "Educación a distancia vía videoconferencia", colaborando en eliminar las barreras anteriormente expuestas y fomentando el abordaje y profundización de esta temática tan trascendente para la mitad de la población del país y para el país todo.
A LOHAS szegmens mérete és jellemzői Magyarországon

Published: March 2018

Az 1990-es évekig a marketing fókuszában azok a cserefolyamatok álltak, amelyekben a hatalom birtokosa a termelő volt. Az erőforrások korlátozottságának és a környezeti kihívásoknak a felismerésével, a harmadik évezred elején olyan globális kérdések foglalkoztatják a marketing szakembereket, mint a fenntartható fejlődés és a fenntartható fogyasztás. Kutatásunk célja a fenntartható értékrend szerinti életstílus elemzésével meghatározni a magyarországi LOHAS fogyasztói csoport nagyságát, melyet három lépésben valósítottunk meg. Elsőként a fenntartható értékrend hazai megjelenését vizsgáltuk faktorelemzés segítségével. Ezt követően elvégeztük a magyar fogyasztók értékrend alapú életstílus szegmentációját k-means klaszterezési eljárás segítségével, végül pedig további szegmentációval megbecsültük a LOHAS értékek iránt legelkötelezettebb fogyasztói csoport nagyságát. Célkitűzésünk volt továbbá, hogy eredményeinket összehasonlítsuk Rácz (2013) azonos módszertannal végzett tudományos munkájának legfontosabb megállapításaival. A kutatás célkitűzéseinek megvalósítására egy 1000 fős országos reprezentatív kérdőíves megkérdezést indítottunk 2013 szeptemberében Magyarországon. Az értékorientált életstílus kutatás során 25 életstílus-állítást fogalmaztunk meg. A 25 állítás 5 tényező mentén került kialakításra, amelyek a következők voltak: környezettudatos értékek, egészségtudatos értékek, etikus értékek, autentikus értékek, individualista értékek. Eredményeink szerint a magyar fogyasztók értékrendjében jelen vannak a fenntarthatóság irányába mutató jellemzők, és azok hat értékkategóriába különülnek el: individualista értékek, autentikus értékek, környezettudatos értékek, etikus kompetenciaértékek, egészségtudatos értékek, etikus vállalati értékek. Az értékdimenziók közül az autentikus értékek, az egészség- és környezettudatosság, valamint az etikus vállalati magatartás meghatározó jelentőségűek a magyar lakosság számára. A fenntartható értékrend mentén öt értékalapú szegmentumot tudtunk elkülöníteni, ezek név szerint az Idősödő közömbösek (16,4%), a Fiatal trendkövetők (32,1%), a Fiatal környezettudatosak (18,6%), az Etikus hagyománytisztelők (22,6%) és a Csalódott pesszimisták (10,3%). A legnagyobb klaszter, a Fiatal trendkövetők csoportja körvonalazza leginkább a LOHAS fogyasztók életstílusának jellemzőit. A szegmens azonban nem tekinthető teljes egészében a LOHAS értékek iránt elkötelezett fogyasztói csoportnak. A legnagyobb heterogenitást az etikus kompetenciaértékek mentén mutatják a Fiatal trendkövetők, ezért szükségesnek tartottuk a csoport további szegmentálását a legelkötelezettebb LOHAS fogyasztók arányának meghatározása érdekében. Az etikus kompetencia- jellemzőket leginkább felülértékelő harmadik alklaszter feleltethető meg a magyar LOHAS fogyasztói csoportnak. Eredményeink alapján arányuk 8,7% a magyar lakosságon belül, amely lényegében megegyezik Rácz (2013) megközelítően 8,0%-os csoportméretével.
