Scaffold Architecture and Properties for Osteoblasts Cell Culture: An Optimization Model and Application by Genetic Algorithm
Authors: Domínguez-Díaz Maraolina , Cruz-Chavez Marco Antonio
Published: February 2015

In the developing of scaffolds for cell culture, a large number of architectures with different combinations of properties should be tested to determine the best. This can be costly in time, money and materials. In this paper we have proposed an optimization model that aims to maximize the growth of osteoblasts on polymeric scaffolds by regulating their properties and architecture. Based on the optimization model it was implemented a genetic algorithm to calculate the architecture and properties of the scaffolds. The fiber diameter, pore diameter, porosity, Young's modulus and contact angle of the scaffolds were calculated through four electrospinning parameters: voltage (kV), concentration (% w/v), flow rate (ml/h) and distance (cm). A fitness value was assigned to each scaffold and the highest one was chosen as the best condition for osteoblast growth. The preliminary results obtained by the Genetic Algorithm were consistent with the tendencies reported experimentally in other studies. Also, the methodology established here can be easily adapted to different types of polymers and cells. Finally, the optimization model can be applied not only by means of heuristic method, like a Genetic Algorithm, but also by exact methods.
Phase Stability of β-Ti Phase in the TiAl Alloys with the Combined Addition of M Elements
Authors: Nakashima Hirotoyo , Takeyama Masao
Published: February 2015

Phase equilibria among the β-Ti, α-Ti and γ-TiAl phases were examined at 1473 K, in order to reveal the M/Nb ratio dependence of the relative phase stability of β phase in the Ti-Al-Nb-M (M: V, Cr, Mo) quaternary systems. In all of the quaternary systems, the expansion of β phase region toward the lower (Nb+M) content side is observed due to the existence of negative interaction to stabilize the β phase between the third and fourth elements (i.e. Nb-V, Nb-Cr and Nb-Mo). Composition dependence of the interaction is quantified as a function of the M/(Nb+M) ratio at 42 at.% Al. The strong interaction energy existing between the different group elements should be taken into account to design the multi-component TiAl alloys.

Published: February 2015

Epilepsy in the elderly has high incidence and prevalence and is often underecognized. Objective To describe etiological prevalence of epilepsy and epileptic seizures in elderly inpatients. Methods Retrospective analysis was performed on elderly patients who had epilepsy or epileptic seizures during hospitalization, from January 2009 to December 2010. One hundred and twenty patients were enrolled. They were divided into two age subgroups (median 75 years) with the purpose to compare etiologies. Results The most common etiology was ischemic stroke (36.7%), followed by neoplasias (13.3%), hemorrhagic stroke (11.7%), dementias (11.4%) and metabolic disturbances (5.5%). The analysis of etiological association showed that ischemic stroke was predominant in the younger subgroup (45% vs 30%), and dementias in the older one (18.9% vs 3.8%), but with no statistical significance (p = 0.23). Conclusion This study suggests that epilepsy and epileptic seizures in the elderly inpatients have etiological association with stroke, neoplasias and dementias.

Published: February 2015

Objective: To investigate the association between CFH gene polymorphism and response to ranibizumab in Brazilian patients with neovascular age-related macular degeneration (AMD).Methods: 95 patients were genotyped for the CFH rs1061170 (Y402H) single nucleotide polymorphism. Patients with neovascular AMD initially received intravitreal ranibizumab injections for three months and were retreated as needed. Visual acuity (VA) and central retinal thickness (CRT) were measured before treatment and at 1, 3, 6, and 12 months post-treatment.Results: For patients with the TT and TC genotypes, paired comparisons of VA showed a statistically significant improvement when the data obtained at all visits were compared with baseline. Patients homozygous for the risk genotype (CC) did not show a statistically significant improvement when VA obtained at visits 1, 3, 6 and 12 were compared with baseline. For all genotypes, paired comparisons of CRT showed a statistically significant improvement when the data obtained at visits 1, 3, 6 and 12 were compared with baseline.Conclusion: Patients with the CC genotype showed poorer long-term functional response to intravitreal ranibizumab.

Objective: To evaluate the effectiveness of cavernostomy in patients with complex fungal balls.Methods: We analyzed the medical records of patients undergoing cavernostomy between January 2005 and May 2013, evaluating: age, gender, preoperative signs and symptoms, predisposing disease, preoperative tests, location of the aspergilloma, etiologic agent, cavernostomy indication, postoperative outcome.Results: Ten patients were male. The mean age was 42.9 years (34-56). The most frequent symptom was repeated pulmonary bleeding. Cavernostomy was proposed for patients at high risk for lung resection. It was performed in 17 patients and all of them had pulmonary tuberculosis sequelae, with cavitations. The indication in all cases was hemoptysis and elimination of phlegm. The cavernostomies were performed in a single surgical procedure. In all 17 patients the cavity was left open after the withdrawal of the mycetoma. In all patients hemoptysis ceased immediately. Operative mortality was 9.5% (1).Conclusion: cavernostomy is an effective treatment alternative in patients at high risk. It may be useful in some patients with complex aspergilloma, irrespective of lung function or bilateral disease. It is technically easy, has low-risk, saves parenchyma, and may be performed in a single operative time.

Este trabalho teve como objetivo avaliar a eficiência de gradientes de densidade contínuos de Percoll e OptiPrep para a separação de espermatozoides portadores do cromossomo X, e avaliar a influência sobre a viabilidade espermática, taxa de prenhez e proporção do sexo. Para isso, 100 milhões de espermatozoides foram depositados em cada tubo contendo o gradiente de densidade, previamente preparados, em tubos de poliestireno, 24 horas antes da centrifugação e mantidos a 4 °C. Centrifugou-se a 500 x g por 15 minutos a 22 °C e, posteriormente, os sobrenadantes foram aspirados e os espermatozoides recuperados no fundo dos tubos. Uma amostra foi avaliada antes a após a centrifugação para verificação da motilidade e vigor espermático. Os espermatozoides foram utilizados para a inseminação artificial em tempo fixo. Os resultados indicaram que a centrifugação não afetou a viabilidade espermática e a taxa de prenhez, entretanto não houve desvio da proporção do sexo para fêmeas. Mais estudos são necessários para determinar a necessidade de adaptação da técnica de centrifugação para a espécie ovina e assim obter o desvio da proporção do sexo como na espécie bovina.

O estudo objetivou descrever a técnica de obliteração do complexo arteriovenoso ovariano (CAVO) por meio da confecção de um nó sob seu próprio eixo, além de avaliar a eficácia desta técnica hemostática na ovariosalpingohisterectomia de gatas, bem como averiguar os tempos parciais de obliteração dos CAVOs e o tempo total do procedimento. Após treinamento prévio, com auxílio de métodos alternativos para ganho de habilidade cirúrgica, foram realizados procedimentos cirúrgicos in vivo. Realizou-se estudo experimental com finalidade de comparar a técnica proposta com a técnica de ligadura com três pinças hemostáticas. O treinamento in vivo, inicialmente em gatas hígidas e, posteriormente, em portadoras de afecções uterinas, serviu para consolidar a destreza adquirida por meio de métodos alternativos e para averiguar a exequibilidade da técnica descrita, que se mostrou eficaz. No estudo comparativo não houve diferença estatística significativa entre o tempo cirúrgico (p=0,2848) e a obliteração do CAVO direito (p=0,1036) entre os dois grupos, porém foram observadas diferenças significativas no tempo de obliteração do CAVO esquerdo (p=0,0001). Diante dos resultados obtidos a partir das avaliações realizadas no período de observação transoperatória, podemos inferir que a técnica descrita é exequível e promove adequada hemostasia do CAVO.

Published: February 2015

Em 2011, o estado do Rio de Janeiro (ERJ) apresentou a mais alta taxa de incidência de tuberculose do país. Realizamos uma pesquisa qualitativa sobre a estrutura, a organização e os processos de trabalho no Programa de Controle da Tuberculose (PCT), por meio de uma análise temática de entrevistas com coordenadores do PCT em 13 municípios do ERJ. A descentralização do controle da tuberculose – por intermédio da incorporação de suas normas pela Estratégia de Saúde da Família (ESF) – exige a reorganização dos processos de trabalho do Programa. A substituição contínua de profissionais da ESF e a estrutura insuficiente do PCT prejudicam o controle da tuberculose. A superação do modelo baseado em um serviço de tratamento especializado requer a integração do PCT a todos os níveis do Sistema Único de Saúde, e atribuição de autonomia aos coordenadores, para tomarem decisões.

Published: February 2015

Dando prosseguimento às pesquisas anteriores realizadas pelo Núcleo de Assistência para o Autocuidado da Mulher (NAAM) sobre aspectos relativos à menstruação, desenvolvemos um trabalho que estudou os conceitos de 705 mulheres sobre sua menstruação. Foram utilizadas informações do banco de dados do NAAM, obtidos na aplicação do Histórico de Saúde da Mulher no Município de Vargem Grande Paulista. O conceito mais relatado pelas mulheres foi o Normal. Isto talvez explique os dados obtidos em trabalhos anteriores, onde muitas mulheres nada fazem para aliviar os sintomas dolorosos da menstruação. O acesso a estes conceitos próprios é importante para elaborar uma assistência de enfermagem de qualidade respeitando as crenças e valores dentro da cultura das mulheres.

This article describes the main directives of Brazilian foreign policy, conceptually defining and characterizing South-South Cooperation, illustrated through an analysis of two Brazilian technical cooperation initiatives in healthcare: one in South America, the other in Africa. The study concludes that, irrespective of the interests and power asymmetries existing in South-South Cooperation, the objectives of this cooperation were achieved through the technical work
Health at the dawn of development: the thought of Abraham Horwitz
Authors: Pires-Alves Fernando A. , Maio Marcos Chor
Published: February 2015

The article explores the ideas of Pan American Health Organization director Abraham Horwitz on the relations between health and development at the time the Alliance for Progress was established, in 1961. Taking development discourse as a public philosophy of international cooperation, the discussion centers on how Horwitz worked to mediate between health and development. Horwitz endeavored to establish arguments that highlighted the importance of social policy, especially in health; he also strove to reach different audiences and drew connections between elements like health, illness, and labor productivity, without ignoring the humanistic considerations so dear to the public health tradition

Authors: Fonseca Luiz Eduardo , Almeida Celia
Published: February 2015

This study centers on relationships among national and international actors in preparation of the first health policy document for East Timor, under the United Nations transitional administration, between 1999 and 2002. International cooperation support for the health system rehabilitation process during the post-conflict period is analyzed as part of reconstruction of the State in parallel with construction of the country's political and institutional framework. Knowledge, ideas, "ways of doing," and induced and accepted practices permeate an interplay of power relationships that condition both national political alliance-building and the architecture of international aid, pointing to input to a discussion of how these mechanisms interact at different conjunctures and times in different negotiating frameworks.

Authors: Ugur Atnan , Maden Hande Ayhan
Published: February 2015

Sweet corn (Zea mays L. var. saccharata) attracts people with its amazing flavour. Adverse environmental factors decrease plant's cob yield and quality. A more effective production can be made by using resistant varieties and adjusting the sowing and plating periods. In this study, the effect of direct seed sowing and cultivating with seedlings in three different times (5, 15 and 25 May) on the sweet corn's cob yield and certain quality features have been investigated. In the research hybrid sweet corn varieties; 2201, Challenger, Merit, Sunshine and Yellow Baby were used. Ear weight, ear yield, ear length, ear diameter, sequence in ear, kernel numbers in the sequence, dry weight, TSS, chroma and hue values have been identified in the study. The values obtained from cultivation with seedling have been found higher in all of the parameters except for TSS. With the progress of cultivation period while TSS and hue values in kernels have increased (9.72 to 20.94) chroma values have decreased. Husked ear weight values have changed between 184.69 to 224.11 g in varieties. The highest ear yield (3594.33 kg da-1) has been obtained from Merit by seedling planting cultivation on 15 May.

Ungendering and Regendering Shelters for Survivors of Human Trafficking
Authors: Hacker Daphna , Levine-Fraiman Yaara , Halili Idan
Published: February 2015

This article is based on intensive fieldwork in the two Israeli shelters designated for victims of human trafficking and slavery. The shelters, one for women and one for men, are a refuge for survivors of sex trafficking; labor migrants subjected to severe exploitation by their employers; and asylum seekers who arrived in Israel after experiencing severe physical and emotional abuse at the hands of kidnappers and smugglers en route to Israel. The study included interviews with policy makers and professionals, and with women and men who resided at the shelters, as well as an analysis of the relevant legislation and official reports. The article explores the problematic gendered differentiations between the two shelters. Most significantly, while support for residents of the shelter for women is anchored by emotional and psychological rehabilitation, residents of the shelter for men do not receive any therapeutic support. At the same time, while staff in the shelter for men put significant effort into the reintegration of the men into the labor force, the women’s employment prospects receive less attention. Based on these and other findings, the article cautions against gender-biased rehabilitation services for victims of human trafficking and slavery, and calls for a gender-sensitive rehabilitation theory and practice.
How dynamic are understory communities and the processes structuring them in mature conifer forests?
Authors: Gendreau-Berthiaume B. , Macdonald S. E. , Stadt J. J. , Hnatiuk R. J.
Published: February 2015

Even though understory plant communities play important roles in northern forest ecosystems, our understanding of their long‐term successional dynamics and the associated driving processes is still limited. This study used spatially explicit data from five, long‐term, permanent plots in mature lodgepole pine (Pinus contorta) stands in the Canadian Rocky Mountains to: (1) assess whether understory communities showed homogenization over time either within or between plots and if compositional changes observed were supportive of either the initial or relay floristics model; and (2) evaluate the relative importance of the environment vs. dispersal limitations in structuring these understory communities and how this changes over time. We found between‐plot convergence and within‐plot homogenization over time, largely due to increasing cover of mosses and later successional species. These changes were mainly in relative abundance, thus supporting the initial floristic model. However, the appearance of late successional species and the disappearance of early successional species over the study period suggested that the relay floristic model was also important. Most of the variation in understory species composition and richness was explained by spatial variables that were independent of environmental factors, suggesting that dispersal limitation was important in these communities. However, environmental variables explained an important fraction of the variation in species richness and composition, especially in more xeric environments; from this we infer that deterministic processes still played an important role in structuring these communities. In most plots, our results also showed increasing importance of dispersal limitations following canopy closure and we attribute this to both the homogenisation of the understory environment and increased abundance of later successional species which were more dispersal limited.

Drug Use, Sexual Risk, and Syndemic Production Among Men Who Have Sex With Men Who Engage in Group Sexual Encounters
Authors: Hirshfield Sabina , Schrimshaw Eric W. , Stall Ronald D. , Margolis Andrew D. , Downing Martin J. , Chiasson Mary Ann
Published: February 2015

Objectives. We surveyed men who have sex with men (MSM) to determine whether sexual risk behaviors, recent drug use, and other psychosocial problems differed between men who engaged in one-on-one and group sexual encounters.

Methods. We conducted an Internet-based cross-sectional survey of 7158 MSM aged 18 years or older in the United States recruited from a gay-oriented sexual networking Web site in 2008. Among MSM who engaged in group sexual encounters, we compared their past-60-day sexual behaviors in one-on-one encounters and group sexual encounters. We also compared risk profiles and syndemic production between men who did and did not participate in group sex.

Results. Men reporting a group-sex encounter had significantly higher polydrug use and sexual risk than did the men not reporting group sex in the past 60 days. The odds of engaging in group sex with 4 or more sexual partners significantly increased with the number of psychosocial problems, supporting evidence of syndemic production.

Conclusions. We identified a particularly high-risk subgroup in the MSM population with considerable psychosocial problems that may be reached online. Research is needed on how to engage these high-risk men in combination prevention interventions.

We systematically reviewed randomized controlled trials of interventions to improve the health of people during imprisonment or in the year after release. We searched 14 biomedical and social science databases in 2014, and identified 95 studies.

Most studies involved only men or a majority of men (70/83 studies in which gender was specified); only 16 studies focused on adolescents. Most studies were conducted in the United States (n = 57). The risk of bias for outcomes in almost all studies was unclear or high (n = 91). In 59 studies, interventions led to improved mental health, substance use, infectious diseases, or health service utilization outcomes; in 42 of these studies, outcomes were measured in the community after release.

Improving the health of people who experience imprisonment requires knowledge generation and knowledge translation, including implementation of effective interventions.
