Caterisano, A, Hutchison, R, Parker, C, James, S, and Opskar, S. Improved functional power over a 5-week period: Comparison of combined weight training with flexible barbell training. J Strength Cond Res 32(8): 2109–2115, 2018—Previous studies demonstrated increased power development with various resistance-training modes over short training periods of 4–7 weeks through neuromuscular adaptations. The purpose of this study was to compare 2 different power-training regimens over a 5-week period: combined weight training program (CT) using speed-lifts and plyometrics vs. flexible barbell (FB) training. College football players (n = 28) were randomly assigned to either FB or CT training groups. The CT group followed a combined weight training program using 45–65% of 1 repetition maximum, and the FB group used an FB with a fixed mass of 56.82 kg for all lifts. Both groups performed similar lifts 4 days per week in a split routine, alternating muscle groups. Subjects were tested before and after the training period by the vertical jump (VJ), long jump, medicine ball (MB) throw, and Margaria-Kalamen stair power test. Pre- to post-tests, both groups experienced significant increases in VJ (CT: 57.9 ± 8.9 to 64.5 ± 7.9 cm, FB: 68.1 ± 6.9 to 74.9 ± 6.6 cm) and MB (CT: 513.3 ± 69.3 to 594.9 ± 78.2 cm, FB: 510.0 ± 41.4 to 613.9 ± 52.6 cm) that were not significantly different between training modes. Long jump improved significantly only in FB (248.4 ± 23.1 to 254.3 ± 24.6 cm) and not in CT. The Margaria-Kalamen stair power test result improved in both groups but FB improved at a significantly higher level than CT (CT: 40.6 ± 2.3 to 44.3 ± 2.2 W, FB: 41.0 ± 1.7 to 48.8 ± 1.8 W). The results suggest that both FB and CT training improved power over a 5-week training period, but that FB training may be more effective than CT in lower-body power development.

Comfort, P, Dos'Santos, T, Thomas, C, McMahon, JJ, and Suchomel, TJ. An investigation into the effects of excluding the catch phase of the power clean on force-time characteristics during isometric and dynamic tasks: an intervention study. J Strength Cond Res 32(8): 2116–2129, 2018—The aims of this study were to compare the effects of the exclusion or inclusion of the catch phase during power clean (PC) derivatives on force-time characteristics during isometric and dynamic tasks, after two 4-week mesocycles of resistance training. Two strength matched groups completed the twice-weekly training sessions either including the catch phase of the PC derivatives (Catch group: n = 16; age 19.3 ± 2.1 years; height 1.79 ± 0.08 m; body mass 71.14 ± 11.79 kg; PC 1 repetition maximum [1RM] 0.93 ± 0.15 kg·kg−1) or excluding the catch phase (Pull group: n = 18; age 19.8 ± 2.5 years; height 1.73 ± 0.10 m; body mass 66.43 ± 10.13 kg; PC 1RM 0.91 ± 0.18 kg·kg−1). The Catch and Pull groups both demonstrated significant (p ≤ 0.007, power ≥0.834) and meaningful improvements in countermovement jump height (10.8 ± 12.3%, 5.2 ± 9.2%), isometric mid-thigh pull performance (force [F]100: 14.9 ± 17.2%, 15.5 ± 16.0%, F150: 16.0 ± 17.6%, 16.2 ± 18.4%, F200: 15.8 ± 17.6%, 17.9 ± 18.3%, F250: 10.0 ± 16.1%,10.9 ± 14.4%, peak force: 13.7 ± 18.7%, 9.7 ± 16.3%), and PC 1RM (9.5 ± 6.2%, 8.4 ± 6.1%), before and after intervention, respectively. In contrast to the hypotheses, there were no meaningful or significant differences in the percentage change for any variables between groups. This study clearly demonstrates that neither the inclusion nor exclusion of the catch phase of the PC derivatives results in any preferential adaptations over two 4-week, in-season strength and power, mesocycles.

Williams, MR Jr, Hendricks, DS, Dannen, MJ, Arnold, AM, and Lawrence, MA. Activity of shoulder stabilizers and prime movers during an unstable overhead press. J Strength Cond Res 34(1): 73–78, 2020—Overhead reaching is a common movement that relies heavily on muscles for dynamic stability. Stabilizer muscle activation increased during squatting and bench pressing with an unstable load, but the overhead press (OHP) has yet to be examined. The purpose of this study is to compare muscle activity of the shoulder stabilizers and prime movers and excursions of the center of pressure (CoP) during the OHP in 2 unstable and one stable conditions. Twelve men (aged 25.3 ± 2.7 years, mass: 91.5 ± 8.4 kg, height: 1.81 ± 0.06 m) pressed 50% of their 1 repetition maximum for 10 repetitions over 3 conditions: a straight stable barbell (SS), a straight unstable (SU) barbell with kettlebells suspend by elastic bands, and an unstable Earthquake (EU) bar with kettlebells suspended by elastic bands. Activity of the shoulder stabilizers and prime movers were measured via surface and indwelling electromyography. Center of pressure excursion of the right foot was also measured. A multivariate analysis was used to determine significant differences between conditions. Pressing with the EQ increased activation of the biceps brachii, erector spinae, latissimus dorsi, pectoralis major, rectus abdominus, rhomboids, and serratus anterior over the SS condition, whereas only the SU condition increased activation in the erector spinae and latissimus dorsi muscles. The EQ condition produced greater CoP excursion (35.3 ± 7.9% foot length) compared with the SU (28.0 ± 7.2% foot length) and SS (22.2 ± 6.3% foot length) conditions. Therefore, the EU condition may be an effective exercise to activate scapular stabilizers.

Botonis, PG, Toubekis, AG, and Platanou, TI. Physiological and tactical on-court demands of water polo. J Strength Cond Res 33(11): 3188–3199, 2019—The purpose of the present review is to provide a quantification of the specific game's activities performed by elite water polo players and a comprehensive overview of the physiological requirements reflecting physical and tactical on-court demands in water polo. Game analysis demonstrates that various swimming movements occur throughout a match play, although approximately 50% of these are recorded in horizontal body position. The various offensive and defensive tactical actions transiently modify the playing intensity, which overall corresponds to the players' lactate threshold. Even play corresponds to 60% of total game actions, whereas the respective percentage of power-play and counterattacks may exceed 30%. The ability to perform high-intensity activities with short recovery periods is critical for water polo players. Elite water polo players present a high level of aerobic power and endurance as indicated by their maximal oxygen uptake and speed at the lactate threshold. Depending on the positional roles, outfield players are characterized as centers or peripherals. The overall physiological load seems to be similar between players at various positions, despite that centers execute more dynamic body contacts, whereas peripherals more swimming bouts. Despite limitations concerning the experimental setting, the current findings indicate that the incidence of fatigue deteriorates playing intensity and performance. Nonetheless, data from the reviewed studies should be cautiously interpreted because in some of the studies, players' substitutions were not allowed. A high conditioning level is essential for water polo, as it is associated with superior technical and tactical efficacy and lower decline of physical or technical performance within the game.

McGhie, D, Østerås, S, Ettema, G, Paulsen, G, and Sandbakk, Ø. Strength determinants of jump height in the jump throw movement in women handball players. J Strength Cond Res 34(10): 2937–2946, 2020—The purpose of the study was to improve the understanding of the strength demands of a handball-specific jump through examining the associations between jump height in a jump throw jump (JTJ) and measures of lower-body maximum strength and impulse in handball players. For comparison, whether the associations between jump height and strength differed between the JTJ and the customarily used countermovement jump (CMJ) was also examined. Twenty women handball players from a Norwegian top division club participated in the study. Jump height was measured in the JTJ and in unilateral and bilateral CMJ. Lower-body strength (maximum isometric force, one-repetition maximum [1RM], impulse at ∼60% and ∼35% 1RM) was measured in seated leg press. The associations between jump height and strength were assessed with correlation analyses and t-tests of dependent r's were performed to determine if correlations differed between jump tests. Only impulse at ∼35% 1RM correlated significantly with JTJ height (p < 0.05), whereas all strength measures correlated significantly with CMJ heights (p < 0.001). The associations between jump height and strength were significantly weaker in the JTJ than in both CMJ tests for all strength measures (p = 0.001–0.044) except one. Maximum strength and impulse at ∼60% 1RM did not seem to sufficiently capture the capabilities associated with JTJ height, highlighting the importance of employing tests targeting performance-relevant neuromuscular characteristics when assessing jump-related strength in handball players. Further, CMJ height seemed to represent a wider range of strength capabilities and care should be taken when using it as a proxy for handball-specific movements.

Published: June 2018

The membrane-forming performance of emulsified wax curing agent (EWCA) and the mechanical properties of the ice layer atop the cement concrete surface were explored via a series of tests in the research of this article. First, the tests for the membrane-forming performance of EWCA atop the glass plates or the cement concrete test blocks were conducted; the thermal endurance of the formed EWCA membrane, its performance against water erosion, the observation of its appearance, and the microstructure were the primary areas of focus in the research. These tests were performed to determine an optimized formula for EWCA and a practical product of EWCA with high performance. This kind of EWCA product was used in the tests for the mechanical properties of the ice layer atop the cement concrete test blocks. The results of these tests indicated that the EWCA product sprayed on the cement concrete surface reduced the sheer bond stress between the ice layer and the cement surface by 62 %, reduced the pull-out bond stress of the ice layer by 38 %, and reduced the impact resistance of the ice layer by 60 %. Thus, it can be concluded that spraying EWCA atop the cement concrete surfaces might improve the efficiency of removing the ice layer from the cement concrete surface.
On the Intensification of Natural Gas-Based Hydrogen Production Utilizing Hybrid Energy Resources
Authors: Pichardo Patricia A. , Manousiouthakis Vasilios I.
Published: June 2018

In this work, parametric studies are carried out for natural gas-based hydrogen production systems utilizing hybrid energy sources, such as natural gas and concentrated solar power (CSP). The main technologies utilized in the considered networks consist of steam methane reforming, reverse water-gas shift, high-temperature shift, and low-temperature shift reactors; ideal hydrogen and carbon dioxide separators; water flash separators; pressure changing devices; and a heat exchange network (HEN). A broad search of the design space is carried out within the Infinite DimEnsionAl State-space conceptual framework, which allows for the simultaneous synthesis of the hydrogen production process and its associated HEN using linear programming. The identified designs minimize the total cost of three hot utilities and one cold utility, subject to bounding constraints on the work of separation and the HEN area. The level of exothermicity of the reforming operations, and the extent of CSP use, are shown to depend on the employed utility cost ratios and the aforementioned work and area bounds.
Children in the Criminal Justice System
Authors: Urbas Gregor , Harris Michael
Published: June 2018

In two decisions handed down in 2016, the High Court of Australia considered legal measures designed to deal with children in the criminal justice system in an age-appropriate manner. The first case, R v GW, was a prosecution appeal involving the unsworn evidence of a child witness. In this decision, the High Court reviewed the common law and statutory background to unsworn evidence, and gave important guidance on the proper approach to dealing with such evidence in proceedings. The second case was RP v The Queen, which involved the criminal responsibility of a child defendant, and in particular the application of the doli incapax presumption. In this decision, the High Court reviewed the common law background to doli incapax, and gave guidance on its application in criminal proceedings. This commentary discusses both cases and the principles underlying the High Court’s reasoning.
Developing a KPI for Measuring Staff Wellbeing
Authors: Clarke Andrew
Published: June 2018

In late 2016, two well-known Australian organisations joined together to produce a new employee wellness index. The national and international firms, Medibank and Deloitte, respectively, promoted the index as enabling firms to measure the collective wellness and wellbeing of their staff. The two firms were of the view that these concepts should become a mainstream issue for boards and management, and form part of CEO accountability to the board. The case was put that responsibility for wellness should become a key performance indicator against which leadership and management performance could be judged. This paper examines the basis for such a proposal in terms of Australia’s system of corporate and tort law. It reviews the implications of a potential employee right to wellbeing. Would this impact, for example, on the established rights and expectations of employees, both individually and collectively? In addition to examining the consequences for relevant law and regulation, this paper reviews the implications in an international context for Australia’s long-established system of shareholder-primacy corporate governance. In particular, does the proposed wellness index invert the shareholder model, and give too much power to employees?

Authors: Uzuner Sibel
Published: June 2018

The present study analyzed the
efficiency of crude pectinase produced from Bacillus subtilis using
hazelnut shell hydrolysate during clarification of apple juice. Response
surface methodology (RSM) based desirability analysis was carried out to
optimize the enzyme load, temperature, and time with respect to lightness,
turbidity and clarity. The apple juice clarification was performed at different
enzyme loads (0.3-0.7%), pH (4-7), temperature (30-50 oC) and time
(2-6 h). The RSM results revealed optimum clarification conditions of 0.3%
(w/v) enzyme load, 45.8 oC temperature, and 2 h of time resulting in
70.40 lightness, 49.44 turbidity and 88.33% clarity. To confirm the validity of
RSM models, RMSE values of L value, turbidity and clarity were calculated as
4.65, 5.28 and 9.15, respectively. As a conclusion, maximum clarity at a low
enzyme load and time makes the enzyme useful for juice industry.

Published: June 2018

ABSTRACT Objectives: To report a case series of squamous cell carcinoma (SCC) in the foot, describing previous risk factors, surgical treatment, histopathological findings, and functional and oncological results. Methods: Nine consecutive patients diagnosed with SCC of the foot were treated at a single institution and prospectively analyzed for risk factors related to the disease, surgical outcome, and histopathological, functional and oncological results. All patients had identifiable risk factors for SCC. Results: Definitive treatment consisted of partial (6 patients) or total (3 patients) amputation of the foot. The functional score was good or excellent in the surviving patients. Early identifiable risk factors are present in most patients. Biopsy when this diagnosis is suspected, in association with oncological principles, avoids diagnostic and treatment errors. Conclusion: Despite delayed diagnosis and surgical treatment with partial and total amputations of the foot in our series, we observed good oncological outcomes that avoided systemic spread of the disease and achieved expected functional results. Level of Evidence V; Case series.

Published: June 2018

RESUMO: As comunidades zooplanctônicas são importantes componentes na cadeia alimentar considerando os produtores primários e os demais níveis. Além disso, algumas espécies são sensíveis ou tolerantes à poluição orgânica. Aqui testamos a hipótese de que a composição de espécies varia conforme o gradiente de eutrofização. Buscou-se estabelecer os possíveis fatores ambientais responsáveis pela variação na distribuição das espécies. Esse estudo teve como objetivo caracterizar a comunidade zooplanctônica e relacionar os dados com a qualidade da água em reservatórios do Estado de São Paulo. Amostras foram coletadas através de arrasto vertical por meio de rede de plâncton (68 (m) em sete corpos d’água. Todos os espécimes foram identificados através de literatura específica e contados em camâra de Sedgwick rafter. Os dados bióticos e abióticos foram analisados através da análise de correspondência canônica. Um total de 67 táxons foram encontrados, sendo Rotifera o predominante. No geral, os reservatórios apresentaram condições eutróficas, principalmente Salto Grande, Barra Bonita e Broa. Os resultados apontaram que os rotíferos Trichocerca longiseta (Schrank, 1802), Hexarthra sp., Brachiounus spp. e Keratella tropica (Apstein, 1907) seguiram o gradiente de eutrofização. Além desses, microcrustáceos como Notodiaptomus, Mesocyclops, Metacyclops e Diaphanossoma ocorreram em reservatórios eutróficos. Por outro lado, os cládoceros Ceriodaphnia cornuta (Sars, 1886) e Bosminopsis deitersi Richard, 1895 foram considerados indicadores de melhor qualidade devido à relação com águas mais transparentes. Os resultados apontam que algumas espécies do zooplâncton são efetivas para o monitoramento ambiental sem descartar as análises físico-químicas e biológicas.

ABSTRACT: The fish assemblage structure in a port area in São Marcos Bay (Amazonic coast) was evaluated based on the spatial and temporal distributions to identify potential changes in response to anthropic pressure increases associated with industrial and port activities in region. The samples were taken between March 2011 and November 2015. The ichthyofauna was represented by a total of 56 species, distributed in 15 orders and 29 families. Captures were dominated by Genyatremus luteus (Bloch, 1790), but Sciades proops (Valenciennes, 1840) was the most representative in terms of biomass. Seasonal distributions of fish assemblage did not reveal significant differences. However, there was a difference between catch sites, abundance, biomass and Shannon diversity index was higher in the Site 1 and evenness in Site 4. The analysis NMDS and the test ANOSIM between months and between sampling sites, based on species composition, revealed a seasonal differentiation associated with the rainy and drought months, as well as spatial differentiation, in function of a depth gradient and hydrodynamics, resulting from greater distance from mangrove areas. The low diversity recorded may be a reflection of port activities that historically occur in the area investigated. However, there was still a maintenance of regional diversity throughout the period under analysis. Thus, temporal and spatial scales become important for the detection and understanding of fish biodiversity in an Amazonian estuary, reflecting, the importance of mangroves for the maintenance of the ichthyofaunistic diversity in the area. In this context, the present study may subsidize possible conservation projects in the area since information of this nature is almost non-existent for estuarine fish from the Maranhão Amazon.
Structure of the ichthyofauna of adventitious streams in the South Pantanal
Authors: Uieda Virginia S. , Fujihara César Y.
Published: June 2018

ABSTRACT: The ichthyofauna of the Taquari River, one of the main tributaries of the South Pantanal, has been studied since the 1970s; however, there is a gap on the studies about the ichthyofauna present on the small adventitious streams of this highly dendritic system. These streams are small tributaries that flow directly into large rivers (mainstem), at least three orders greater in magnitude. The aim of this study was to analyze the structure of the ichthyofauna of five adventitious streams of the Upper Taquari River, South Pantanal, evaluating its temporal variation (dry and wet season) and the relation to the habitat characteristics and the conservation of the streams. Thirty-seven species were collected, from which 14 are exclusive to the Paraguay River basin, one species [Apteronotus albifrons (Linnaeus, 1766)] could represent a new record for this basin, and six species need taxonomic confirmation. The analysis indicated only the existence of spatial variation in the ichthyofauna structure of the streams sampled, with the similarity patterns related to the distance between the streams and to their conditions of conservation. The stream with greater size and preserved riparian forest was the one with the highest values of fish diversity and evenness. On the other hand, the stream with the smallest percentage of riparian forest and highest proximity to urban area presented the lowest diversity. The small size of these adventitious systems should serve as protection against large predators, which have their access to those areas hampered by their own size. Otherwise, the mainstem may also act as source of dispersal of small-bodied schooling fishes to the adventitious streams, where the greater heterogeneity of habitats and the presence of riparian vegetation should offer shelter and food supply for small species.

ABSTRACT Objective To verify the interference of the energy intake under-reporting in the determination of the dietary patterns and nutrient intakes reported by obese women in the waiting list for bariatric surgery. Methods The study included 412 women aged 20 to 45 years with a body mass index ranging from 35 to 60kg/m2 who were on waiting list for bariatric surgery. Data from three reported food intake and physical activity, body weight, and height were used for estimating the reported energy intake, physical activity level, and resting energy expenditure. Subsequently, it was checked the biological plausibility of the reported energy intakes, classifying all participants as plausible reporters or under-reporters. Exploratory factor analysis was used to determine the participants’ dietary patterns. The Mann-Whitney test assessed the reported energy and nutrient intakes between plausible reporters and under-reporters groups. The Z-test assessed the variables of plausible reporters or under-reporters in relation to all participants of the study. Results Six dietary patterns were determined for all participants of study. After excluding information from under-reporting women, only two dietary patterns remained similar to those of all participants, while three other dietary patterns presented different conformations from food subgroups to plausible reporters. The reported energy intake did not present difference for the subgroups of fruits, leaf vegetables and vegetables. However, the energetic value reported for the other food subgroups was higher for the plausible reporters. Conclusion The under-reporting of energy intake influenced the determination of dietary patterns of obese women waiting for bariatric surgery.

Published: June 2018

Abstract Introduction: Among the menstrual disorders of the female reproductive period, Premenstrual Syndrome (PMS) and Dysmenorrhea are the most prevalent. The intensity of the signs and symptoms in each of these conditions may compromise the physical, psychological and social well-being of the woman at the stage of the menstrual cycle. Objective: To compare the signs and symptoms of menstrual disorders in women who practice regular exercise or not. Methods: A cross-sectional study carried out on women who practice exercises regularly and sedentary women. The IPAQ questionnaires and the evaluation of signs and symptoms of dysmenorrhea and PMS were applied to non-sedentary and sedentary students from the Federal University of Sergipe, Campus Lagarto. Results: Both groups had similar data for mean age and the mean Body Mass Index (BMI), therefore, passive of comparison. The prevalence of dysmenorrhea was significantly higher among sedentary women, 82% in the sedentary group and 46% in the non-sedentary group (p < 0.001), as well as some negative impacts on the psychological, social and physical state of both PMS and dysmenorrhea. Conclusion: The prevalence of signs and symptoms of dysmenorrhea was significantly higher in the Sedentary Group. Analyzing the behavior of PMS in relation to the practice of physical exercises, it was observed that the signs and symptoms of depressed mood, fatigue, difficulty to concentrate, lack of interest in social and home activities were more significant in the Sedentary Group.

Abstract Objective: To identify health promotion actions carried out by professionals in the Family Health Strategy in relation to elderly people. Method: An exploratory study with a qualitative approach was performed in Juazeiro do Norte, Ceará, Brazil, with 19 professionals. A recorded, fully transcribed semi-structured interview was used after authorization by the ethics committee under number 501 675. The discussions were analyzed using Content Analysis, organized into thematic categories. Results: Actions of a collective nature were identified, such as activities in groups, meetings, conversation circles, lectures and guidance in the waiting room. Other directed actions were used, such as guidelines during individual consultations and referral to specialized services. Conclusion: The need for the discussion of health promotion and actions in relation to old age was highlighted, with debate and reflection on this theme required locally, along with the need to build a network of support for the health of the elderly in a shared manner among professionals, managers and the community.

Abstract Objective: To analyze training in integrated health care for the elderly from the perspective of nursing students. Method: A descriptive and exploratory study with a qualitative approach was carried out using the action research method with the participation of 24 nursing students from a university center in Piauí, Brazil. Data were obtained through semi-structured interviews and submitted to content analysis. Results: Two thematic categories emerged: Perspectives on aging, violence and sexuality and A holistic approach to the elderly: integrating training and care. Conclusion: The perspective of the students on integrated care for the elderly is fragmented, stemming from the limitations of the training process for such care.

Abstract Objectives: To compare burden and sociodemographic profile and to analyze the care needs of caregivers of elderly persons enrolled in Social Care Referral Centers in a municipal region in the interior of the state of São Paulo, Brazil. Method: A cross-sectional, quantitative-qualitative study was carried out. A sociodemographic questionnaire, the Zarit Burden Scale and three open questions regarding care needs were applied. The quantitative data were analyzed by descriptive statistics and the correlation test. The hermeneutic-dialectic referential was applied and the qualitative data were analyzed by the content analysis technique. Results: A total of 86 caregivers participated in the study. The majority were female (71.7%), had a mean age of 56.5 (sd=14.9) years, suffered burden and lived in vulnerable neighborhoods. With regard to care, the provision of support for activities of daily living, difficulties in caring and the help of other relatives were identified. Burden negatively correlated with age range and schooling (r=-0.11; r=-0.87). Conclusion: Guidance and the acquisition of caring skills remain unprovided by the resources and services that exist in vulnerable contexts, and resolutive support strategies are lacking in public facilities.
A Integração do Telessaúde nas Centrais de Regulação: a Teleconsultoria como Mediadora entre a Atenção Básica e a Atenção Especializada

Published: June 2018

RESUMO Em 2007, o Ministério da Saúde, com o objetivo de desenvolver ações de apoio às equipes de atenção básica por meio da educação permanente e de tecnologias virtuais, instituiu o Programa Telessaúde Brasil, mais tarde denominado Telessaúde Brasil Redes. Inicialmente, no projetopiloto, foram constituídos nove Núcleos de Telessaúde no Brasil, sendo um deles em Santa Catarina, vinculado à Universidade Federal de Santa Catarina e posteriormente com parceria da Secretaria Estadual de Saúde (SES). Um dos serviços ofertados pelo Núcleo de Telessaúde de Santa Catarina é a teleconsultoria, que se trata de consulta registrada e solicitada por profissionais de saúde com o fim de esclarecer dúvidas sobre procedimentos clínicos, de gestão e processo de trabalho, realizada por meio de telecomunicação bidirecional à distância. Embora o serviço esteja disponível desde sua implantação, seu uso sempre foi numericamente pequeno, ao passo que há grande quantidade de encaminhamentos desnecessários à atenção especializada com possibilidade de manejo na atenção básica. Este trabalho relata a experiência da implantação de fluxo compulsório de teleconsultoria antes do encaminhamento às especialidades, ocorrida no Núcleo de Telessaúde de Santa Catarina. O estabelecimento do fluxo compulsório demonstrou que grande parte dos casos apresenta sugestão de manejo na atenção básica, com diminuição importante do número de encaminhamentos às especialidades envolvidas e consequente diminuição do tempo de espera para consulta com o especialista. Além disso, nestes casos de sugestão de encaminhamento, a teleconsultoria possibilita a classificação de risco, a solicitação prévia de exames e o manejo compartilhado, qualificando, desta forma, o acesso à especialidade e o próprio cuidado ao usuário. A teleconsultoria potencializa ainda a qualidade da comunicação entre os pontos de atenção, pois ela passa a ser estratégica na definição do fluxo do usuário, tanto para a referência, quanto para a contrarreferência, com aprendizado mútuo e funcionamento que de fato caracteriza uma rede de cuidados. Quanto à compulsoriedade da teleconsultoria, ainda que cause alguns desconfortos no início do processo, o uso incipiente do serviço quando da modalidade espontânea, o número de encaminhamentos desnecessários às especialidades e a quantidade de teleconsultorias com possibilidade de manejo na atenção básica justificam a decisão como propósito de gestão. Esse conjunto de aspectos tem impacto positivo no cuidado do usuário, que tem suas necessidades atendidas e acompanhadas, seja na atenção básica ou na atenção especializada, em tempo, situação e local oportunos.

Authors: Caligaris Gastón , Starosta Guido
Published: June 2018

El objetivo de este artículo es discutir la interpretación marxista dominante respecto del significado de lo que Marx llamó el “elemento histórico y moral” del valor de la fuerza de trabajo y ofrecer una lectura alternativa que sea consistente con los fundamentos de la crítica marxiana de la economía política. Para tal fin, en la primera parte del artículo, se realiza una crítica de dicha interpretación basada en el reconocimiento de su génesis histórica y su filiación con la base textual y fundamentos de la crítica marxiana de la economía política. En la segunda parte, se realiza una reconstrucción crítica del legado de Marx respecto a la determinación del valor de la fuerza de trabajo y se presenta una resignificación del elemento histórico y moral en cuestión.
No meio do caminho havia um mangue: impactos socioambientais da estrada Bragança-Ajuruteua, Pará
Authors: Oliveira Marcus Vinicius Cunha , Henrique Márcio Couto
Published: June 2018

Resumo O artigo investiga os impactos socioambientais da construção da rodovia PA-458, que aterrou 26km de manguezal entre o município de Bragança e a praia de Ajuruteua, no nordeste do Pará. Com base em documentos oficiais, jornais, fotografias e relatos orais foram analisadas as representações de políticos, moradores e mariscadores de caranguejo sobre os significados da rodovia. Conclui-se que as autoridades desconsideraram os impactos ambientais causados no manguezal e no cotidiano dos mariscadores de caranguejo, que, mesmo avaliando a estrada como positiva, são confrontados com a escassez progressiva do crustáceo e com o aumento do número de atravessadores.
Human Primary T Cells: A Practical Guide v1

Published: June 2018

Human primary T cells are invaluable and feasible model systems to study the characteristics of the human immune cells in various contexts, including but not limited to cancer immunotherapy. Following isolation of T cells from fresh human blood samples, it is possible to culture, expand, and manipulate these cells, which allows extensive investigation for research purposes. Techniques for isolation and handling of T cells are well-established but parts of the protocols can highly vary across different labs. These differences in the protocols are, often, there due to historical reasons and are only supported by anecdotal evidence. We systematically modified basic components of the T cell culturing protocols and collected data on how they altered the final yield. Here, based on these data, we provide practical hints and tips on basic cellular and molecular techniques for handling primary human T cells. We hope that this guide will serve as a reference point to allow evaluate, discuss, and improve current practices in T cell culturing and manipulation.

Analysis of teaching resources used in EFL classes in selected Ecuadorian universities
Authors: Acosta Hazel , Cajas Diego
Published: June 2018

This study looks at how Communicative Language Teaching (CLT) is implemented in Ecuadorian universities through analysis of teaching resources that teachers use in classes. A survey was conducted through the administration of a questionnaire. A total of 65 teachers responded to the survey. The results indicated that in developing productive skills, group-oriented activities such as pair-and-share scheme and role-plays are frequently conducted, and the use of worksheets, translator applications and audio materials were often used in developing students’ receptive skills.  Teachers did not often use resources on pronunciation activities, direction-oriented tasks and translation using Spanish. Analysis of frequently used resources showed that teachers tried to develop students’ communicative competence, one of the core principles of CLT, however, most of these resources were not teacher-made but support materials of textbooks produced by publishing houses abroad. Too much dependence on these resources influences teacher interaction with students and also diminishes the role of the teacher as the frontline source of language use especially in listening and speaking when audio materials and worksheets replace the teachers’ voice. Indeed, the selection of a teaching resource is as crucial as the method employed in CLT implementation in EFL classroom.
A Lefebvrian Analysis of Public Spaces in Mangaung, South Africa
Authors: Nkooe Ernestina S.
Published: June 2018

Hoffman Square, Driehoek Neighbourhood Park and Old Regional Park are public spaces in Mangaung. Henri Lefebvre’s The Production of Space and Elements of Rhythmanalysis are explored in the analysis of these public spaces’ organised representations, representational uses and rhythmic spatial practices. This article found that: (1) public spaces in Mangaung are lived spaces that are regularly appropriated by inhabitants whose unpoliced social practices of vandalism and littering—along with the harsh regional climate—deteriorate the physical quality of the public spaces, secreting environmental incivility in the public spaces; (2) cyclical rhythms of night and day times have a practical impact on the spatial practices of each public space in spite of their design and location. For example, day-time entails high and rapid levels of public space uses while night-time diffuses these dynamics significantly; and (3) Mangaung’s spatial plans encourage the liberal uses of its public spaces however, it fails to enforce its by-laws to curb experienced physical decay of, and environmental incivility in, the public spaces. This increases the vulnerability of its public spaces to external shocks—emanating from nature and society—thus depriving the public spaces of an opportunity to be perceived as alternatives for urban regeneration and local economic revitalisation.
COMPARISON OF 14C-UREA BREATH TEST WITH GASTRIC HISTOLOGY FOR DIAGNOSIS OF HELICOBACTER PYLORI INFECTION AMONG PATIENTS WITH PEPTIC ULCER DISEASE
Authors: Alkarboly Taha , Husein Hiwa , Faraj Heero
Published: June 2018

Background

Helicobacter pylori infection is common among patients with peptic ulcer disease. The definitive means of diagnosing infection being histology requires endoscopy and sedation making it invasive and expensive. The carbon urea breath test is generally considered to be a simple, non-invasive and accurate test for the detection of Helicobacter pylori infection both before and after treatment.

Objectives 

Our objective was to compare histology with a less invasive and safer method, the 14C-urea breath test.

Materials and Methods

After approval of Ethical committee of the Iraqi Board for Medical Specialties, informed consent were taken from every patient before esophagogastroduodenoscopy. Fifty patients with peptic ulcer disease diagnosed by endoscopy were evaluated by 14C-urea breath test. Four biopsies were taken for histology. After endoscopy, each patient was evaluated by both tests for diagnosis of Helicobacter pylori infection

Results

50 patients with peptic ulcer disease Helicobacter pylori infection was diagnosed in 35 patients (63.45%), while in 15 patients (36.55%) were negative for Helicobacter pylori infection using gastric histology and urea breath test. Compared with histology, the diagnostic values of the 14C-urea breath test were: sensitivity 94%, specificity 87%, positive predictive value 94%, and negative predictive value 87%. 

Conclusion

The 14C-urea breath test is a noninvasive diagnostic tool for Helicobacter pylori infection. It’s a sensitive and specific test with excellent positive predictive value and its good negative predictive value guarantee its usefulness in clinical practice.
