Authors: Nguyen Luu Huu 
Published: May 2018

In this study, the influence of particle size distribution in the range of σ =0-0.4 on the specific loss power (SLP) in magnetic fluids based on nanoparticles (NPs) of 6 materials of FeCo, La0.3Sr0.7MnO3, MnFe2O4, g-Fe2O3, CoFe2O4 and FePt was evaluated using Linear Response Theory (LRT). Results show that while the particle diameters Dcp of maximum SLP remain unchanged, the SLPmax values decrease with increasing size distribution for all the studied materials. The reduction behaviors can be classified into 2 groups, namely group with strong and weak decrease rate for low-anisotropy (FeCo, La0.3Sr0.7MnO3, MnFe2O4, g-Fe2O3), and high-anisotropy (CoFe2O4 and FePt) materials, respectively.

Abstract

Background
The purpose of this study was to review the risks and benefits of concurrent chemoradiation therapy (CCRT) with esophageal self-expandable metal stents (SEMS) for the treatment of locally advanced esophageal cancer.

Materials and Methods
Between January 2014 and December 2016, the data from 46 locally advanced esophageal cancer patients who received CCRT at our institution were retrospectively reviewed. Eight patients who received CCRT concomitant with SEMS placement (SEMS plus CCRT group) and thirty-eight patients who received CCRT without SEMS placement (CCRT group) were identified. The risk of developing esophageal fistula and the overall survival of the two groups were analyzed.

Results
The rate of esophageal fistula formation during or after CCRT was 87.5% in the SEMS plus CCRT group and 2.6% in the CCRT group. The median doses of radiotherapy in the SEMS plus CCRT group and the CCRT group were 47.5 Gy and 50 Gy, respectively. SEMS combined with CCRT was associated with a greater risk of esophageal fistula formation than CCRT alone (hazard ratio [HR], 72.30; 95% confidence interval [CI], 8.62–606.12; p &lt; .001). The median overall survival times in the SEMS plus CCRT and CCRT groups were 6 months and 16 months, respectively. Overall survival was significantly worse in the SEMS plus CCRT group than in the CCRT group (HR, 5.72; 95% CI, 2.15–15.21; p &lt; .001).

Conclusion
CCRT concomitant with SEMS for locally advanced esophageal cancer results in earlier life-threatening morbidity and a higher mortality rate than treatment with CCRT alone. Further prospective and randomized studies are warranted to confirm these observations.

Implications for Practice
Patients treated with SEMS placement followed by CCRT had higher risk of esophageal fistula formation and inferior overall survival rate compared with patients treated with CCRT alone. SEMS placement should be performed cautiously in patients who are scheduled to receive CCRT with curative intent.
A reforma do ensino superior no contexto da reforma do estado brasileiro
Authors: Brandim Maria Rejane Lima , Feldmann Marina Graziela 
Published: May 2018

A Reforma do Estado brasileiro estabelecida nos anos 90 do século XX durante o governo de Fernando Henrique Cardoso (1995-2002) é o ápice da ascensão das políticas neoliberais no país, representadas pelo forte ajuste fiscal e a implantação de um Estado mínimo, conformando o estabelecimento de diminuição ou corte nos gastos públicos e a progressiva privatização de empresas estatais e de serviços públicos de uma maneira geral. Esta reforma, configura-se como a primeira geração de reformas neoliberais brasileiras que buscam, especificamente, a redefinição do estado e do que lhe é atividade exclusiva e do que será considerado seu corpo de servidores.A segunda geração de reformas acontece nos anos do governo de Lula da Silva (2003-2010), numa expressiva complementaridade ás reformas iniciadas no governo anterior, ainda que estas se mostrem contrárias às necessidades dos trabalhadores brasileiros em geral e fortemente marcadas pelas diretrizes dos organismos internacionais do capital tais como o Banco Mundial e o Fundo Monetário Internacional, para os chamados países periféricos. Entre os anos de 2003 e 2007, no contexto da Reforma do Estado, passou então a ser institucionalizada a reforma do ensino superior brasileiro, que ganha corpo com a adoção de um conjunto de medidas, dentre elas, o Programa de Apoio aos Planos de Reestruturação e Expansão das Universidades Federais (REUNI), implantado por Decreto lei em 2007. Propomo-nos a analisar, a partir de uma pesquisa bibliográfica, a política de expansão do ensino superior brasileiro efetivada no contexto da reforma do estado e as transformações educacionais determinadas por essa política, implantadas nas instituições publicas de ensino superior no período de 2007-2012. Buscamos identificar nessa expansão, a configuração de um processo efetivo de democratização do acesso ao ensino superior no Brasil. Nossos estudos, até o momento, apontam para um aumento significativo de instituições federais criadas no periodo, para o aumento das matrículas, para a expansão de campi, para o aumento na contratação de docentes. Contudo, identificamos problemas na implantação do REUNI, no que diz respeito principalmente à estrutura física com novas Universidades e Campi de Expansão em processo de construção; à estrutura pedagógica e curricular, com novos cursos criados cujos Projetos pedagógicos encontravam-se em fase de elaboração; ao trabalho docente precarizado pela sobrecarga de disciplinas e o acúmulo de outras atividades afins ao exercício do magistério superior.

Published: May 2018

Introduction:Providing collaborative care is essential to decrease cardiovascular complications of hypertension (HTN). Care coordination models, including the Patient Centered Medical Home (PCMH), are advocated to manage chronic diseases. However, they offer no guidance on collaborative strategies to improve patient outcomes. This project enhanced the PCMH model at a Federally Qualified Health Center (FQHC) through application of interprofessional collaboration (IPC) concepts including role optimization, shared decision making, shared power, and care expertise.Methods:Application of IPC concepts with the key addition of a pharmacist education component was instituted at a Midwestern FQHC over a 60-day period with a single care team. Inclusion criteria included adult patients with a diagnosis of uncontrolled primary HTN (>140/90). Blood pressure, perception of IPC, and patient and care team satisfaction were measured. Descriptive statistics, paired t-test, and unpaired t-test were used for analysis.Results:Twenty-two patients participated in the process change. Mean BP demonstrated a statistically significant decline. Care team perception of IPC improved. Care team members and patients reported satisfaction with the overall process change.Conclusion:This project offers support to increase knowledge of how IPC competencies and concepts can be incorporated into an FQHC and the effect it may have on hypertensive patients being treated under a PCMH model.
Densidad mineral ósea en niños celiacos. Indicaciones de estudio y efecto de la exclusión del gluten de la dieta
Authors: Jorquera Plaza Francisco 
Published: May 2018

Introducción:Una de sus principales manifestaciones extradigestivas de la enfermedad celiaca es la disminución de la densidad mineral ósea (DMO). La densitometría ósea realizada con DXA es el método de elección para la valoración de la DMO. Las indicaciones de su uso en niños celiacos son controvertidas.Objetivos:Analizar la DMO y diversas variables clínico-analíticas en niños celiacos cuando son diagnosticados y tras realizar una dieta sin gluten. Definir un perfil de pacientes con mayor probabilidad de presentar afectación de la DMO en base a diversas características individuales, para realizar indicaciones de DXA.Métodos:Estudio realizado 24 niños celiacos (12 varones) (Edad: 8,7±3,3 años). Mediante DXA se determinó su DMO al diagnóstico y tras realizar dieta sin gluten. La DMO fue comparada en cada paciente en los dos momentos del estudio y al diagnóstico entre grupos de pacientes estratificados según criterios de gravedad dependientes de variables clínicas, analíticas e histológicas. Resultados: La DMO fue normal en todos los pacientes estudiados en el momento del diagnóstico y tras realizar tratamiento, sin apreciarse diferencias entre esos dos momentos del análisis. Los niños que presentaban sintomatología cuando eran diagnosticados de enfermedad celiaca tuvieron menor DMO en columna y fémur que los asintomáticos. La calcemia tuvo correlación inversa con el tiempo de evolución de la enfermedad antes de su diagnóstico.Conclusiones:En general, en nuestro medio, no está indicada la realización de estudio de la mineralización ósea en los niños celiacos, salvo cuando haya existido una evolución clínica prolongada antes del diagnóstico.

Published: May 2018

Abstract
In this paper, alternative reservoir operation models under different environmental operating conditions were developed to analyze the impacts of applying different policies in a multi-reservoir system in order to balance human and environmental requirements. Three scenarios/models were developed under four sub-scenarios/operating conditions. The scenarios were: (1) an optimization model to maximize the hydropower production, (2) an optimization model to minimize the squared of the difference between the release and need, (3) a simulation model under the Hydropower Standard Operating Policy. The sub-scenarios were developed as follows: (i) no environmental flow, (ii) minimum environmental flow, (iii) environmental flow bounded by the minimum and maximum flow, and (iv) maximum environmental flow. Hydropower production and system performance criteria were calculated and compared in all cases. Moreover, the Range of Variability Approach was used to assess the hydrological alterations of each of the 12 cases. The results in a two reservoir cascade of Seimare-Karkheh, located within the Karkheh River Basin in Iran, showed that sub-scenario 3 performed best in all three scenarios. Further comparison indicated that scenario 1, under sub-scenario 3, was a good compromise solution, as it provided adequate hydropower production and performance criteria and the least hydrological alterations.

Background:2,4-disubstituted-1,3-thiazole derivatives (2a–j), (3a–f) and (4a–f) were synthesized, characterized and screened for their potential as antimicrobial agents. In the preliminary screening against a panel of bacterial strains, nine compounds showed moderate to potent antibacterial activity (IC50 = 13.7-90.8 μg/ml). </P><P> Methods: In the antifungal screening, compound (4c) displayed potent antifungal activity (IC50 = 26.5 &#181;g/ml) against Candida tropicalis comparable to the standard drug, fluconazole (IC50 = 10.5 &#181;g/ml). Based on in vitro antimicrobial results, compounds 2f, 4c and 4e were selected for further pharmacological investigations. Hemolytic activity using human red blood cells (hRBCs) and cytotoxicity by MTT assay on human embryonic kidney (HEK-293) cells revealed non-toxic nature of the selected compounds (2f, 4c and 4e). To ascertain their possible mode of action, docking studies with the lead inhibitors (2f, 4c and 4e) were performed using crystal structure coordinates of bacterial methionine aminopeptidases (MetAPs), an enzyme involved in bacterial protein synthesis and maturation.Results:The results of in vitro and in silico studies provide a rationale for selected compounds (2f, 4c and 4e) to be carried forward for further structural modifications and structure-activity relationship (SAR) studies against these bacterial infections.Conclusion:The study suggested binding with one or more key amino acid residues in the active site of Streptococcus pneumoniae MetAP (SpMetAP) and Escherichia coli MetAP (EcMetAP). In silico physicochemical properties using QikProp confirmed their drug likeliness.
