Published: July 2015

At present, multiple sclerosis is regarded as disease in which the immune system fights its own cells, in this case the nervous tissue. The World Health Organisation (WHO) estimates that 2.5 million people in the world suffer from multiple sclerosis, of which 40-60 come from Poland. The costs incurred in relation to the disease are high due to the duration of the disease, a quick loss of the ability to work by people suffering from it, and due to the high costs of immuno-suppressive treatment and broad medical care.
The use of alloplastic biomaterials in the surgical treatment of aggressive periodontitis – a case report
Authors: Kiernicka Małgorzata , Kiernicki Krzysztof , Rahnama Mansur
Published: July 2015

Periodontitis is a commonly encountered disease of the mouth, in man. This inflammatory process results in the impairment of the connective tissue attachment and alveolar bone resorption. Guided tissue regeneration, which aims at rebuilding the lost periodontal tissue and restoring its function, involves the use of barrier membranes and bone substitutes. This paper presents an aggressive periodontitis treatment with the use of a combination of alloplastic biomaterials applied in the anterior maxillary region of a 38-year-old female patient. The used biomaterials, i.e. hydroxyapatite and calcium sulfate, served as space fillers, the latter was also used as a barrier membrane. Satisfactory therapy results obtained in the patient were maintained throughout a 21-month postoperative follow-up period. Alloplastic materials appear to be useful in regeneration of the periodontal structures and may serve an alternative to xenografts and allogenic grafts.
The influence of selected variables on the values of systolic pressure in patients with hypertension
Authors: Szymańska Jolanta , Pietryka-Michałowska Elżbieta
Published: July 2015

Hypertension is a disease of the first world and results to a great extent from leading an improper lifestyle. Some important risk factors include being overweight or obese, indulging in little physical activity, smoking and abusing alcohol. The aim of this study was to analyze the influence of some selected variables, including lifestyle choices, on systolic blood pressure in patients treated for hypertension. The study was conducted among 132 patients using the medical services in five randomly selected clinics in Lublin. The influence of age, sex, body mass index, physical activity and smoking on systolic blood pressure was analyzed. The study shows that systolic blood pressure depends on the selected variables. In general, however, a positive correlation was found between age and systolic blood pressure, regardless of gender. Moreover, a higher systolic blood pressure was also observed in men, as well as in individuals with low physical activity, in those who smoke and those who are overweight or obese. Our results indicate that patients with hypertension should be aware that drug therapy and lifestyle are integral components of disease treatment, and modification of their lifestyles towards leading healthy ones is a necessity.
Advising Experiences and Needs of Online, Cohort, and Classroom Adult Graduate Learners
Authors: Schroeder Shawnda M. , Terras Katherine L.
Published: July 2015

Although a majority of graduate students fall under the definition of adult learners (over age 24 years), many traditional institutions do not offer advising specific to them, nor do they recognize advising needs of these older students in online, classroom, or cohort situations. In this phenomenological study, 9 adult graduate learners were interviewed, 3 from each learning environment, to understand and explain the perceived advising needs and experiences within and among learning environments. Findings suggest that adult learners, regardless of learning environment, require complex and holistic advising. Five themes of good graduate advising are discussed. The need for immediate advisor response varied with respect to participants' learning environments. Implications for practice are discussed.
Impact of the 2013 ASCO/CAP HER2 Guideline Updates at an Academic Medical Center That Performs Primary HER2 FISH Testing
Authors: Muller Kristen E. , Marotti Jonathan D. , Memoli Vincent A. , Wells Wendy A. , Tafe Laura J.
Published: July 2015

Objectives:

The 2013 American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guideline updates lowered the threshold for HER2 positivity and altered the equivocal category. The goal of this study was to evaluate the impact of these changes on the distribution of HER2 fluorescence in situ hybridization (FISH) status. The utility of reflex HER2 immunohistochemistry (IHC) for FISH equivocal cases was also examined.

Methods:

We retrospectively reviewed all invasive breast cancers analyzed for HER2 via dual-probe FISH (PathVysion; Abbott Laboratories. Abbott Park, IL) 12 months before and after the HER2 guidelines updates were implemented. Reflex HER2 IHC results were recorded for HER2 FISH equivocal cases.

Results:

There was a significant increase in the number of HER2 FISH equivocal results after the guideline updates (4.9% vs 1.4%, P = .0087) that was independent of specimen type (core vs surgical, P = .6). All 17 FISH equivocal cases after the updates had reflex HER2 IHC: two (12%) of 17 were positive, 12 (71%) of 17 remained equivocal, and three (18%) of 17 were negative.

Conclusions:

Implementation of the 2013 ASCO/CAP HER2 guideline updates resulted in an increase in HER2 FISH equivocal results, which can be attributed to HER2 copy number, regardless of the HER2/CEP17 ratio. Reflex IHC for FISH equivocal cases is of limited utility; however, IHC does assign HER2 positivity or negativity in a small percentage of cases.

Published: July 2015

Objectives:

While many studies have demonstrated problems with informed consent in current practice, there remains controversy on how to address this. The aim of this study was to evaluate the opinions, attitudes, practices, and training for informed consent.

Methods:

Medical students, residents, advanced practice providers, and attending physicians at an academic institution were invited to complete a survey on informed consent for transfusions and procedures through an electronic platform.

Results:

Most (94%, n = 304) respondents indicated previous training in informed consent, only 60% (n = 192) felt the training was adequate, and 35% (n = 92) indicated difficulties with informed consent. When asked what would aid in obtaining consent, 59% (n = 189) selected a written guideline, and 36% (n = 117) selected patient simulation.

Conclusions:

Only 60% of respondents felt their informed consent training was adequate. Multiple areas of difficulty in obtaining proper informed consent were identified that should be addressed with focused training or written guidelines.

Published: July 2015

We report a case of 51 â€“year-old female with history of laparoscopic cholecystectomy presented with abdominal pain and diagnosed as small bowel obstruction caused by adhesions. The initial presentation was periumbilical pain with nausea and vomiting. Plain abdominal radiograph showed dilated small bowel loops and multiple air fluid levels. Due to failure of conservative treatment, laparotomy was performed. An open metallic clip was adhering the bowel to the gallbladder fossa causing sharp angulation. A phytobezoar proximal to this angulation was exteriorized through enterotomy. The patient was recovered smoothly and discharged from our hospital.
Performance Evaluation of the Effect of waste paper on Groundnut Shell Briquette
Authors: Oyelaran Olatunde A , Bolaji Bukola O , Waheed Mufutau A , Adekunle Micheal F
Published: July 2015

Current energy shortage and environmental issues resulting from the use of fossil fuels have lead to exploitation of renewable energy resources that includes municipal waste and agricultural residues. These residues are available, indigenous and are environmental friendly but some can not be used directly in combustion process due high moisture content and low volumetric energy unless by briquetting. The study was undertaken to assess the combustion characteristic of binderless briquettes produced from waste paper and groundnut shell. Combustion characteristics investigated were ignition time, burning time, calorific values, burning rate, specific fuel consumption, fuel efficiency and water boiling time. The calorific values of the briquettes ranged from 19.51 - 19.92 MJ/kg, while the thermal efficiency ranges between 13.75 – 21.64%, other results shows that the average burning rate between 0.511 and 1.133 kg/hr and the specific fuel consumption ranges between 0.087 and 0.131 J/g. The recorded boiling time values were between 17.5 and 30.0 minutes for cold start and 15.0 and 20.0 minutes for hot start. The results shows that waste paper and groundnut shell up to 25% in composition composite briquettes were found to have good combustion characteristics which qualify them as alternative to firewood for domestic and industrial energy. However, production of briquettes from waste paper and groundnut shell at mixing ratio of 85:15 was found to comparatively better from all experiment conducted.

Published: July 2015

Ten secreted aspartic proteases (Saps) of Candida albicans cleave numerous peptides and proteins in the host organism and deregulate its homeostasis. Human kininogens contain two internal antimicrobial peptide sequences, designated NAT26 and HKH20. In our current study, we characterized a Sap-catalyzed cleavage of kininogen-derived antimicrobial peptides that results in the loss of the anticandidal activity of these peptides. The NAT26 peptide was effectively inactivated by all Saps, except Sap10, whereas HKH20 was completely degraded only by Sap9. Proteolytic deactivation of the antifungal potential of human kininogens can help the pathogens to modulate or evade the innate immunity of the host.

Este estudo objetivou analisar a associação da força de preensão manual com morbidades referidas e multimorbidade em adultos de Rio Branco, Acre, Brasil, mediante inquérito de base populacional com 1.395 adultos de ambos os sexos. As associações, por sexo, foram estimadas com a técnica de regressão logística. A média de força de preensão manual nos homens (44,8kg) é maior que entre as mulheres (29kg) e reduz com a idade. A diferença da força de preensão manual média entre aqueles classificados como fortes e fracos foi 21kg e 15,5kg, para homens e mulheres, respectivamente. Controlando para a faixa etária, índice de massa corporal e atividade física quando relevante, homens com baixa força de preensão manual tiveram maiores chances de ocorrência de hipertensão [OR = 2,21 (1,35; 3,61)], diabetes [OR = 4,18 (1,35; 12,95)], distúrbio musculoesquelético [OR = 1,67 (1,07; 2,61)] e multimorbidade [OR = 1,99 (1,27; 3,12)]. Nas mulheres, associações entre força de preensão manual e evento cardiovascular, dislipidemia, distúrbio muscolesquelético e multimorbidade não se mantiveram nos modelos multivariados. Este estudo endossa o uso da força de preensão manual como biomarcador de saúde.

Published: July 2015

O objetivo do trabalho foi apresentar uma proposta de diferenciação das Regiões de Saúde no Brasil, baseada no desenvolvimento humano, contribuindo para a identificação de espaços geográficos comparáveis para observação, análise e acompanhamento do desempenho dos sistemas regionalizados de saúde. Os valores das dimensões do Índice de Desenvolvimento Humano Municipal foram calculados para as Regiões de Saúde pela agregação dos dados dos municípios, ponderados pelo seu tamanho populacional. O agrupamento das Regiões de Saúde em 5 grupos, segundo combinações de longevidade, riqueza e escolaridade, foi determinado pelo método K-Médias. Metade das Regiões de Saúde brasileiras foi classificada em grupos do tipo 1 e 2 e a outra metade em grupos dos tipos 3 a 5. A tipologia apresentada oferece um modelo de agrupamento de Regiões de Saúde homogêneas, coerente com os pressupostos teóricos do PROADESS. A opção por indicadores e métodos de agregação bem estabelecidos tende a favorecer a sua compreensão e utilização pelos atores ligados à gestão do Sistema Único de Saúde (SUS).

Authors: Wittkopf Priscilla Geraldine , Cardoso Fernando Luiz , Sperandio Fabiana Flores
Published: July 2015

Introduction Recent studies with Physiotherapy students pointed out for attitudes and conflicting perceptions on their learning process during the phase that precedes the clinical practice. One of those aspects is the human sexuality that appears in the close physical contact that demands Physiotherapists professional practices. Objective To build up the first educational/research instrument that evaluates the knowledge, the comfort and the attitudes of Physiotherapy undergraduate students (SKCAPS). Materials and methods From the literature we extracted three dimensions: knowledge, comfort and attitudes. Initially 50 items were created distributed in the three dimensions that went under the content evaluation, 47 items survived from this process and integrate the first version of SKCAPS. In empiric terms the intern coherence and the reliability of the instrument were tested in 248 students. Results The exploratory factorial analysis carried 37 items in 4 factors that explain 68% of the total variance of the answers of the subjects and that confirmed the proposed dimensions. The dimension comfort became separated in comfort and discomfort. The SKCAPS presented good reliability in terms of intern consistence alpha 0.861. Finally, the instrument was administered to 30 Physiotherapy students for evaluation of clarity following the exclusion of two items that resulted in averages below 8.5. Conclusions With the aim of improve the teaching/learning process, we propose the SKCAPS as the first worth and reliable instrument to evaluate the knowledge, the comfort, the discomfort and the attitudes regard of human sexuality among Physiotherapy students.

Objetivou-se compreender o conhecimento de pessoas surdas em saúde e doença e suas fontes de informações em um estudo descritivo, com abordagem qualitativa, realizado em uma instituição pública de referência, no estado da Paraíba, em atendimento a pessoas com deficiência. Foram realizadas entrevistas individualmente, em língua de sinais, com 11 pessoas surdas escolhidas pelo método de saturação do conteúdo das falas. Os dados foram analisados segundo a análise de conteúdo. Das falas, emergiram as categorias: processo saúde-doença e fontes de informações de saúde. Os surdos entrevistados nesse estudo apresentaram um conhecimento limitado sobre o processo saúde-doença. Os sujeitos valorizam o médico como imprescindível para o processo saúde-doença. Alguns surdos expuseram não conhecer sobre saúde, devido a fontes precárias e pouco eficientes, disponibilizando informações primárias, sem profundidade de conteúdos, e, por isso, reivindicam mais oportunidades.

Neste estudo foi avaliado o perfil metabólico de vacas leiteiras no período de transição durante o verão e o inverno. Foram utilizados 31 animais pluríparos mestiços girolando em cada estação, totalizando 62 vacas. No verão permaneciam em pasto com suplementação de silagem de milho e concentrado. No inverno, a exigência nutricional era suprida apenas com silagem de milho e concentrado. Foram feitas um total de 11 coletas de sangue de cada animal segundo o seguinte protocolo: quatro coletas pré-parto espaçadas semanalmente, no dia do parto e com 2, 5, 10, 15, 21 e 30 dias pós-parto. Foram avaliadas as concentrações de cálcio, fósforo e magnésio. Todos os analitos variaram em função do estatus fisiológico. As concentrações médias de cálcio e magnésio foram maiores no verão do que no inverno. Em ambas as estações, as menores concentrações médias de cálcio ocorreram próximas ao parto, sendo que 75% dos animais no inverno e 35,48% dos animais no verão estavam hipocalcêmicos. Apenas no décimo dia as concentrações de cálcio voltaram aos níveis do pré-parto, demonstrando que esse tempo é necessário para a adaptação da nova condição de lactante. As concentrações de magnésio foram menores no pós-parto do que no pré-parto nas duas estações, demonstrando a necessidade desse mineral para a produção de leite. As concentrações médias de magnésio permaneceram sempre dentro dos valores de referência, porém 19% dos animais aos dois dias pós-parto no inverno e 7% dos animais aos 10 dias pós-parto no verão tinham concentrações inferiores a esses limites. As concentrações de fósforo sofreram grande variação ao longo do peri-parto, porém sempre em níveis elevados, sendo que 49,8% dos animais no inverno e 37,3% no verão tinham níveis de fósforo acima dos valores de referência
Avaliação ultrassonográfica do aparelho reprodutor em serpentes vivíparas da família Boidae

Published: July 2015

A reprodução faz parte do ciclo de vida dos animais permitindo a perpetuação e a conservação das espécies. Em serpentes, existe uma escassez de informações técnicas a respeito do ciclo reprodutivo. Este estudo teve o objetivo de avaliar o aparelho reprodutivo por meio da ultrassonografia em serpentes vivíparas cativas da família Boidae, permitindo diagnosticar as diferentes fases reprodutivas. Foram avaliadas ultrassonograficamente onze serpentes adultas de quatro espécies da família Boidae: Eunectes murinus, Boa constrictor constrictor, Corallus hortulanus e Epicrates cenchria pertencentes ao acervo do Museu Biológico do Instituto Butantan, São Paulo Brasil. Para a avaliação ultrassonográfica, as serpentes foram contidas fisicamente com gancho herpetológico e depois manualmente por aproximadamente 15 minutos. A avaliação foi feita aplicando-se gel acústico sobre a pele e posicionando o transdutor na linha lateral-ventral direita e esquerda, em região medial do corpo em sentido crânio-caudal. O exame ultrassonográfico permitiu avaliar todo o ciclo reprodutivo nas serpentes. Nas avaliações ultrassonográficas das fêmeas pode-se definir as fases de desenvolvimento ovariano e ovidutal. Os folículos ovarianos durante a fase pré-vitelogênica foram visualizados como homogêneos e anecogênicos, em forma de "cacho de uva". Já na fase vitelogênica, os folículos estavam maiores e mais ecogênicos seguidos uns dos outros, como um "colar de pérolas". Quando não houve cópula, os folículos foram reabsorvidos dentro do ovário retornando a fase pré-vitelogênica. Na fase pós ovulatória foram visualizados três estágios bem definidos de desenvolvimento fetal dentro do oviduto: 1) logo após a ovulação (e fecundação), somente o vitelo foi visualizado; 2) o vitelo ocupava 60% e o feto 40% do ovo e 3) o feto estava formado e não havia vitelo. Nos machos, os testículos foram visualizados como uma imagem homogênea e hipoecogênica quando se encontravam em estágio reprodutivo. Quando não estavam reprodutivos não era possível visualizar a imagem do testículo devido ao seu tamanho. A avaliação ultrassonográfica do aparelho reprodutor em serpentes demonstrou ser uma técnica de diagnóstico segura, não invasiva e que permite o acompanhamento das principais fases reprodutivas
Seleção e parâmetros genéticos de progênies de coentro tolerantes ao calor

Published: July 2015

O coentro é uma hortaliça bastante apreciada como condimento. Em Pernambuco, a cultivar Verdão é uma das mais plantadas, porém um dos problemas dessa cultivar tem sido o seu pendoamento precoce. Cultivares com maior período de crescimento vegetativo e tolerantes ao pendoamento precoce têm sido procuradas pelos produtores. Entretanto, são poucas as pesquisas realizadas no Brasil com cultivares de coentro com essas características. Uma alternativa seria identificar populações promissoras para obtenção de linhagens adaptadas ao calor dentro da cultivar Verdão, uma vez que essa cultivar apresenta ciclo curto e variabilidade genética para este caráter. O objetivo deste trabalho foi estimar parâmetros genéticos e predizer o valor genético de progênies de meio-irmãos de coentro pela metodologia dos modelos lineares mistos (procedimento REML/BLUP) quanto aos caracteres número de dias para início do pendoamento, altura de plantas, diâmetro do caule e massa fresca, além de estimar o número mínimo de progênies adequado para representar uma população de coentro derivada da cultivar Verdão. Oitenta e cinco progênies de meio-irmãos do segundo ciclo de seleção recorrente foram conduzidas em dois experimentos. Foram obtidas estimativas de herdabilidade altas e relações CVg/CVe superiores à unidade para todos os caracteres avaliados, exceto para altura de plantas. A estimativa de parâmetros genéticos permitiu concluir que as progênies de coentro apresentam variabilidade genética para os caracteres número de dias para início do pendoamento, diâmetro do caule e massa fresca. O número mínimo de progênies adequado para estimar os parâmetros genéticos e representar a população de coentro é de 68. Treze progênies de meio-irmãos podem ser selecionadas para dar continuidade ao programa de melhoramento de coentro para tolerância ao calor.
CONTEMPORARY ARAB MUSIC VIDEO CLIPS: BETWEEN SIMULATING MTV’S GENDER STEREOTYPES AND FOSTERING NEW ONES
Authors: Elouardaoui Ouidyane
Published: July 2015

MTV was the first 24-hour cable network to continuously broadcast music videos in the 1980s, thus establishing the genre. Generally, Arab music video clips differ from Western-produced music videos, because artists are compelled to abide by the conservative cultural norms of Arab societies. However, most Arab music videos, particularly those produced in the last decade, reaffirm Western gender stereotypes intrinsic to those produced by MTV. Contemporary Arab music videos for the most part simulate an MTV aesthetic vocabulary of a gaze that features female sexuality and narratives of seduction. Some new Arab producers, nonetheless, have attempted to avoid reproducing MTV-based gender clichés, but have instead created new gender misconceptions. These productions emphasize depictions of women as untrustworthy and impetuous.  Finally, I discuss how young Arab singers have constantly been confronted by the ire of regionally prominent religious figures who denounce the music videos’ endorsement of “anti-Islamic” principles. I contend that Stuart Hall and Paddy Whannel’s early analysis of reactions against popular music styles among British youth as a form of cultural transgression remains relevant to understanding the cultural style of Arab youth as expressed through popular musical performance.

Early Social-Emotional Functioning and Public Health: The Relationship Between Kindergarten Social Competence and Future Wellness
Authors: Jones Damon E. , Greenberg Mark , Crowley Max
Published: July 2015

Objectives. We examined whether kindergarten teachers' ratings of children’s prosocial skills, an indicator of noncognitive ability at school entry, predict key adolescent and adult outcomes. Our goal was to determine unique associations over and above other important child, family, and contextual characteristics.

Methods. Data came from the Fast Track study of low–socioeconomic status neighborhoods in 3 cities and 1 rural setting. We assessed associations between measured outcomes in kindergarten and outcomes 13 to 19 years later (1991–2000). Models included numerous control variables representing characteristics of the child, family, and context, enabling us to explore the unique contributions among predictors.

Results. We found statistically significant associations between measured social-emotional skills in kindergarten and key young adult outcomes across multiple domains of education, employment, criminal activity, substance use, and mental health.

Conclusions. A kindergarten measure of social-emotional skills may be useful for assessing whether children are at risk for deficits in noncognitive skills later in life and, thus, help identify those in need of early intervention. These results demonstrate the relevance of noncognitive skills in development for personal and public health outcomes.
Grab a Cup, Fill It Up! An Intervention to Promote the Convenience of Drinking Water and Increase Student Water Consumption During School Lunch

Published: July 2015

Objectives. We evaluated a low-cost strategy for schools to improve the convenience and appeal of drinking water.

Methods. We conducted a group-randomized, controlled trial in 10 Boston, Massachusetts, schools in April through June 2013 to test a cafeteria-based intervention. Signage promoting water and disposable cups were installed near water sources. Mixed linear regression models adjusting for clustering evaluated the intervention impact on average student water consumption over 359 lunch periods.

Results. The percentage of students in intervention schools observed drinking water during lunch nearly doubled from baseline to follow-up compared with controls (+9.4%; P < .001). The intervention was associated with a 0.58-ounce increase in water intake across all students (P < .001). Without cups, children were observed drinking 2.4 (SE = 0.08) ounces of water from fountains; with cups, 5.2 (SE = 0.2) ounces. The percentage of intervention students observed with sugar-sweetened beverages declined (–3.3%; P < .005).

Conclusions. The current default of providing water through drinking fountains in cafeterias results in low water consumption. This study shows that an inexpensive intervention to improve drinking water’s convenience by providing cups can increase student water consumption.

Published: July 2015

Objectives. We evaluated the effect of an alternative dental workforce program—Kansas’s Extended Care Permit (ECP) program—as a function of changes in oral health.

Methods. We examined data from the 2008 to 2012 electronic medical records of children (n = 295) in a Midwestern US suburb who participated in a school-based oral health program in which preventive oral health care was delivered by ECP dental hygienists. We examined changes in oral health status as a function of sealants, caries, restorations, and treatment urgency with descriptive statistics, multivariate analysis of variance, Kruskal–Wallis test, and Pearson correlations.

Results. The number of encounters with the ECP dental hygienist had a statistically significant effect on changes in decay (P = .014), restorations (P = .002), and treatment urgency (P = .038). Based on Pearson correlations, as encounters increased, there was a significant decrease in decay (–0.12), increase in restorations (0.21), and decrease in treatment urgency (–0.15).

Conclusions. Increasing numbers of encounters with alternative providers (ECP dental hygienists), such as with school-based oral health programs, can improve the oral health status of low-income children who would not otherwise have received oral health services.

Objectives. We explored whether collective concerns about the safety, effectiveness, and necessity of influenza vaccines mediate racial/ethnic disparities in vaccine uptake among health care workers (HCWs).

Methods. We used a self-administered Web-based survey to assess race/ethnicity (exposure), concerns about influenza vaccination (mediator; categorized through latent class analysis), and influenza vaccine uptake (outcome) for the 2012 to 2013 influenza season among HCWs at St. Jude Children’s Research Hospital in Memphis, Tennessee. We used mediation analysis to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) for the total, direct, and indirect effects of race/ethnicity on influenza vaccine uptake.

Results. Non-Hispanic Blacks had lower influenza vaccine uptake than non-Hispanic Whites (total effect: PR = 0.87; 95% CI = 0.75, 0.99), largely mediated by high concern about influenza vaccines (natural indirect effect: PR = 0.89; 95% CI = 0.84, 0.94; controlled direct effect: PR = 0.98; 95% CI = 0.85, 1.1). Hispanic and Asian HCWs had modestly lower uptake than non-Hispanic Whites, also mediated by high concern about influenza vaccines.

Conclusions. Racial/ethnic disparities among HCWs could be attenuated if concerns about the safety, effectiveness, and necessity of influenza vaccines were reduced.
Unintended Consequences of Screening for Ebola
Authors: Faherty Laura Johnson , Doubeni Chyke A.
Published: July 2015

Ebola virus disease (EVD) reached the United States in September 2014, leading the Centers for Disease Control and Prevention to publish screening guidelines to identify patients with high-risk exposures at their first point of contact with the health care system.

In West Africa, the burden of EVD is superimposed on the trauma of decades of civil war, violence, and poverty. Therefore, an important consideration in implementing screening procedures in the United States is the potential to unintentionally exacerbate posttraumatic stress disorder, or add additional stress from stigma and discrimination, among the West African diaspora.

We recommend rigorous research to develop and implement evidence-based, trauma-informed approaches to screening for communicable diseases during outbreaks, using principles of community-engaged or community-based participatory research.
Natural background levels for chemicals in Icelandic aquifers

Published: July 2015

Information about natural background levels (NBLs) of chemicals in source waters allows water utilities to identify trends in drinking water contamination. We estimate NBLs for chemicals in source waters for Icelandic water utilities at both national levels with all data pooled, and according to geological regime. NBLs were derived by collecting samples from 79 aquifers considered largely unimpacted by human activities. The aquifers were categorized into four geological settings that are representative of the geology of Iceland. NBLs were calculated as 90%iles of all aquifers in each setting and in all pooled. There was a statistical difference between the geological settings in 11 parameters of 37 tested. The 90%ile for nitrate for all aquifers pooled was 1.36 mg/l, indicating little anthropogenic influence on water used for public water supply in Iceland. The results were compared to the chemical status of 60 European aquifers, collected for the European Union's Sixth Framework Program Background Criteria for the Identification of Groundwater Thresholds project, revealing lower dissolved solids concentration for Icelandic groundwater than that from other parts of Europe. The explanation is likely due to high permeability of young geology settings and low population density in Iceland whereas there is a long history of agriculture and industry in most European countries.

Published: July 2015

The removal of Acid Black 1 (AB1) and Basic Red 2 (BR2) from aqueous solutions via an electrocoagulation (EC)/Moringa oleifera seeds (MOS) adsorption coupling process by using aluminum and stainless steel electrode in a batch reactor is described in this study. The influences of the operational parameters, i.e. current density, MOS dosage, and dye initial concentration, on degree of color removal were studied, and the unit energy demand, the unit electrode material demand, and the charge loading were calculated and discussed. The amounts of adsorbent and energy consumption were considered as main criteria of process evaluation, and ideal conditions were chosen. The addition of an appropriate MOS dosage (0.6 g/L for AB1 and 5 g/L for BR2) resulted in faster decolorization of dyes especially at lower current densities and was simultaneously accompanied by a significant reduction in contact time compared to the conventional simple EC process. The coupling process achieved degree of removals above 99.3% and 94% for AB1 and BR2, respectively. The EC/MOS coupling technique could be recommended to replace the conventional simple EC because of its high degree of removal, short contact time, and low energy consumption.
Urban drainage system planning and design – challenges with climate change and urbanization: a review
Authors: Yazdanfar Zeinab , Sharma Ashok
Published: July 2015

Urban drainage systems are in general failing in their functions mainly due to non-stationary climate and rapid urbanization. As these systems are becoming less efficient, issues such as sewer overflows and increase in urban flooding leading to surge in pollutant loads to receiving water bodies are becoming pervasive rapidly. A comprehensive investigation is required to understand these factors impacting the functioning of urban drainage, which vary spatially and temporally and are more complex when weaving together. It is necessary to establish a cost-effective, integrated planning and design framework for every local area by incorporating fit for purpose alternatives. Carefully selected adaptive measures are required for the provision of sustainable drainage systems to meet combined challenges of climate change and urbanization. This paper reviews challenges associated with urban drainage systems and explores limitations and potentials of different adaptation alternatives. It is hoped that the paper would provide drainage engineers, water planners, and decision makers with the state of the art information and technologies regarding adaptation options to increase drainage systems efficiency under changing climate and urbanization.
Decentralized peri-urban wastewater treatment technologies assessment integrating sustainability indicators
Authors: Mena-Ulecia Karel , Hernández Heykel Hernández
Published: July 2015

Selection of treatment technologies without considering the environmental, economic and social factors associated with each geographical context risks the occurrence of negative impacts that were not properly foreseen, working against the sustainable performance of the technology. The principal aim of this study was to evaluate 12 technologies for decentralized treatment of domestic wastewater applicable to peri-urban communities using sustainability approaches and, at the same time, continuing a discussion about how to address a more integrated assessment of overall sustainability. For this, a set of 13 indicators that embody the environmental, economic and social approach for the overall sustainability assessment were used by means of a target plot diagram as a tool for integrating indicators that represent a holistic analysis of the technologies. The obtained results put forward different degrees of sustainability, which led to the selection of: septic tank + land infiltration; up-flow anaerobic reactor + high rate trickling filter and septic tank + anaerobic filter as the most sustainable and attractive technologies to be applied in peri-urban communities, according to the employed indicators.
Institutional and policy analysis of wastewater (re)use for agriculture: case study Hyderabad, India
Authors: Saldías C. , Speelman S. , Amerasinghe P. , van Huylenbroeck G.
Published: July 2015

Wastewater constitutes an alternative water source for the irrigation sector. To fully benefit from it, and reduce possible adverse effects on public health and the environment, we need to look at the regulation of the practice. A prerequisite for this is an institutional analysis, and the points to consider are the institutional mandates. We used the city of Hyderabad, India, as a case study. There, irrigation with wastewater is not supported or recognized, but it happens in practice. It takes place in an indirect and unplanned way. Institutions fail at enforcing regulations, and little attention is given to formalization of the practice. With this article, we aim to untangle the institutional setup, and by doing so, identify the constraints surrounding development of a formal practice. Ultimately, we aim at contributing to the discussion on the agricultural use of wastewater.

Published: July 2015

In order to find the dynamic characteristics of shale gas reservoirs and improve shale gas well production, it is
very important to research on shale gas seepage mechanism and production evaluation. Based on the shale gas seepage
mechanism, adsorption and desorption characteristics, the diffusion mechanism and mass conservation theory in shale gas
development, the dual pore medium shale gas reservoir mathematical model is set up. The mathematical model is built by
the finite difference method based on start-up pressure gradient, slippage effect and the isothermal adsorption principle,
and then programmed to solve it. Finally, this paper analyzed the impact of Langmuir volume, Langmuir pressure, start-up
pressure gradient and slippage coefficient and other factors on shale gas wells production.
The esse-essentia distinction in the Summa Contra Gentiles, II 52-54
Authors: Milidrag Predrag
Published: July 2015

The article analyzes Aquinas?s arguments for real distinction between essence
and being (esse) as presented in the chapters 52-54 of the second book of the
Summa contra gentiles, in the wider context of his metapyhsics. First, the
paper analyzes the determinations of God on the basis of real distinction
(Ipsum esse subsistens, creator, infinite perfection), and after that it
analyzes the role of the act and potency, priority of act, separation of the
act from the form in Aquinas?s understanding of esse, as well as the concept
of existential participation; in doing so, the difference among those
concepts in Plato and Aristotle and in Aquinas is accentuated. At the end,
the paper analyzes the role of two kinds of causality, efficient and formal
in real distinction.
