Background Ureteral catheters are valuable indispensable devices may readily acquire biofilms on the inner or outer surfaces. This study evaluated the efficacies of ureteral catheters impregnated with ciprofloxacin, N-acetylcysteine each alone and in combination on microbial adherence. Methods Antimicrobial durability of ureteral catheters coated, through instant dip method, with ciprofloxacin were determined using modified Kirby-Bauer method. Ciprofloxacin-coated catheters showed zones of inhibition ranged from 15 to 45 mm in diameter (baseline) against nine clinical strains recently isolated from patients undergoing ureteral stent removal. Segments coated with ciprofloxacin, N-acetylcysteine each alone and in combination, through instant dip method, were incubated with the tested microorganisms, washed, sonicated, cultured and the number of viable cells were determined. Results Ciprofloxacin-coated catheters soaked in urine and incubated at 37 °C, maintained antimicrobial activities and produce zones of inhibition that measured 2–10 mm for at least 8 weeks. Effect of ciprofloxacin and N-acetylcysteine coated catheters on microbial adherence were found to be dose dependent. Catheters impregnated with ciprofloxacin/N-acetylcysteine showed the highest inhibitory effect on microbial adherence when compared with controls (85.5%–100%). Conclusion Catheters impregnated with ciprofloxacin, using instant dip method, were shown to have broad spectrum, prolonged antimicrobial durability and high efficacy. On the other hand, Catheters impregnated with ciprofloxacin/NAC showed the highest inhibitory effect on microbial adherence to stent surfaces.

PurposeThe purpose of this Phase II randomized-controlled trial was to evaluate the safety and effect of administering several doses of lycopene to men with clinically localized prostate cancer, on intermediate endpoint biomarkers implicated in prostate carcinogenesis.MethodsForty-five eligible men with clinically localized prostate cancer were supplemented with 15, 30 or 45 mg of lycopene or no supplement from biopsy to prostatectomy. Compliance to study agent, toxicity, changes in plasma lycopene, serum steroid hormones, PSA and tissue Ki-67 were analyzed from baseline to completion of intervention.ResultsForty-two of forty-five five subjects completed the intervention for approximately 30 days from the time of biopsy until prostatectomy. Plasma lycopene increased from baseline to post treatment in all treatment groups with greatest increase observed in the 45 mg lycopene-supplemented arm compared to the control arm without producing any toxicity. Overall, subjects with prostate cancer had lower baseline levels of plasma lycopene similar to those observed in previous studies in men with prostate cancer. Serum free testosterone decreased with 30 mg lycopene supplementation and total estradiol increased significantly with 30 mg and 45 mg supplementation from baseline to end of treatment, with no significant increases in serum PSA or tissue Ki-67. These changes were not significant compared to the control arm for this sample size and duration of intervention.ConclusionsAlthough antioxidant properties of lycopene have been hypothesized to be primarily responsible for its beneficial effects, our study suggests that other mechanisms mediated by steroid hormones may also be involved.
Estimation of Accurate and New Method for Hemodialysis Dose Calculation
Authors: Azar Ahmad T. 
Published: November 2017

BackgroundThe Kt/V value demonstrates the dose of hemodialysis (HD). However, because of several existing methods for calculating delivered dialysis dose, Kt/V values can, in fact, be different for the same set of pre-/post-dialysis blood urea concentrations.MethodsIn the study presented here, another formula was derived for calculating Kt/V from the pre- and post-dialysis BUN. We prospectively compared the Kt/V values obtained using this new formula and the Kt/V values obtained via the other existing formulae to see whether reliance on the latter approach was likely to lead to errors in over- or underprescribing dialysis regimens. Data were processed on 268 dialysis patients.ResultsThe estimated Kt/V (Kt/Vest) values were statistically different (p < 0.05) from the calculated Kt/V values from other models, except for those Kt/V values calculated according to the lowrie (P = 0.112), Keshaviah (P = 0.069), Daugirdas First Generation (P = 0.059), Basile (P = 0.102), Ijely (P = 0.286) and Daugirdas Second Generation (P = 0.709). The best correlations were seen with the Daugirdas second generation formula (R = 0.958 and R2= 0.919).ConclusionSince the best correlations were seen between Kt/Vestand the Daugirdas second generation Kt/V we can demonstrate that these two models are more accurate than the other models.

Published: November 2017

ABSTRACT

Background
Electronic reminders for clinical patient counseling have proven to be an effective response to national recommendations to increase risk factor and birth cohort hepatitis C virus (HCV) screening. It is not known whether a resident-led educational intervention alone could increase screening rates where support for electronic intervention may be limited.

Objective
We determined whether a resident-designed and resident-implemented educational intervention would significantly improve HCV screening rates in primary care clinics.

Methods
The baseline HCV screening rate was determined retrospectively in our resident community-based primary care clinics. We then implemented an educational intervention that included presenting during resident conference, posting signs in resident work areas, and providing educational pamphlets to patients. We collected screening rate data at 3 and 6 months postintervention. The screening rate was defined as patients screened in clinic divided by the number of patients eligible for screening.

Results
The screening rate increased significantly from preintervention (6%, 64 of 1023) to 3 months (35%, 363 of 1026) and 6 months (41%, 443 of 1070) and between 3 and 6 months (P &lt; .001). The percentage of screened patients who pursued testing increased significantly between preintervention (62%, 16 of 26) and 6 months (81%, 105 of 130), and between 3 months (67%, 95 of 141) and 6 months (P = .019).

Conclusions
An educational intervention designed and implemented by residents significantly increased the screening and testing rates for HCV in community-based resident clinics.

Published: November 2017

<p>El presente trabajo analiza los nuevos retos a los que, en el marco del Espacio Europeo de Educación Superior, se enfrentan los estudios jurídicos y, en especial, los de Derecho Romano. En él se profundiza sobre las diferentes formas a través de las que un recurso docente, como la tutoría grupal, puede ser útil para este proyecto. Una especial atención se dedica a su papel en la preparación de la asignatura Trabajo Fin de Grado. Muchas de las competencias, genéricas y específicas, adquiridas durante los años de estudio del Grado deben ser utilizadas para su elaboración, de ahí la importancia que tiene como termómetro de calidad de la formación dada y del aprendizaje verdaderamente logrado. La tutela del mismo realizada en pequeños grupos, de cuatro o cinco alumnos como máximo, de acuerdo con la estructura metodológica de un seminario, enriquece cada uno de los trabajos realizados y permite al profesor evaluar el proceso educativo del alumno con mayor realismo. La necesidad de proponer instrumentos adecuados para su eficaz gestión nos ha llevado a adoptar este recurso, basándonos en una experiencia de innovación docente previa puesta en marcha con éxito desde hace más de una década como actividad voluntaria. Los resultados obtenidos son altamente satisfactorios tanto para los alumnos, que aprenden a trabajar cooperativamente, como para su tutor, que está en condiciones de proporcionar al alumno un asesoramiento más completo e integral.</p><p> </p>

The influence of sea- and land-breeze circulations on the diurnal variability in precipitation over a tropical island
Authors: Zhu Lei , Meng Zhiyong , Zhang Fuqing , Markowski Paul M. 
Published: November 2017

Abstract. This study examines the diurnal variation in precipitation over Hainan Island in the South China Sea using gauge observations from 1951 to 2012 and Climate Prediction Center MORPHing technique (CMORPH) satellite estimates from 2006 to 2015, as well as numerical simulations. The simulations are the first to use climatological mean initial and lateral boundary conditions to study the dynamic and thermodynamic processes (and the impacts of land–sea breeze circulations) that control the rainfall distribution and climatology. Precipitation is most significant from April to October and exhibits a strong diurnal cycle resulting from land–sea breeze circulations. More than 60 % of the total annual precipitation over the island is attributable to the diurnal cycle with a significant monthly variability. The CMORPH and gauge datasets agree well, except that the CMORPH data underestimate precipitation and have a 1 h peak delay. The diurnal cycle of the rainfall and the related land–sea breeze circulations during May and June were well captured by convection-permitting numerical simulations with the Weather Research and Forecasting (WRF) model, which were initiated from a 10-year average ERA-Interim reanalysis. The simulations have a slight overestimation of rainfall amounts and a 1 h delay in peak rainfall time. The diurnal cycle of precipitation is driven by the occurrence of moist convection around noontime owing to low-level convergence associated with the sea-breeze circulations. The precipitation intensifies rapidly thereafter and peaks in the afternoon with the collisions of sea-breeze fronts from different sides of the island. Cold pools of the convective storms contribute to the inland propagation of the sea breeze. Generally, precipitation dissipates quickly in the evening due to the cooling and stabilization of the lower troposphere and decrease of boundary layer moisture. Interestingly, the rather high island orography is not a dominant factor in the diurnal variation in precipitation over the island.
Calibration of a simple and a complex model of global marine biogeochemistry
Authors: Kriest Iris 
Published: November 2017

Abstract. The assessment of the ocean biota's role in climate change is often carried out with global biogeochemical ocean models that contain many components and involve a high level of parametric uncertainty. Because many data that relate to tracers included in a model are only sparsely observed, assessment of model skill is often restricted to tracers that can be easily measured and assembled. Examination of the models' fit to climatologies of inorganic tracers, after the models have been spun up to steady state, is a common but computationally expensive procedure to assess model performance and reliability. Using new tools that have become available for global model assessment and calibration in steady state, this paper examines two different model types – a complex seven-component model (MOPS) and a very simple four-component model (RetroMOPS) – for their fit to dissolved quantities. Before comparing the models, a subset of their biogeochemical parameters has been optimised against annual-mean nutrients and oxygen. Both model types fit the observations almost equally well. The simple model contains only two nutrients: oxygen and dissolved organic phosphorus (DOP). Its misfit and large-scale tracer distributions are sensitive to the parameterisation of DOP production and decay. The spatio-temporal decoupling of nitrogen and oxygen, and processes involved in their uptake and release, renders oxygen and nitrate valuable tracers for model calibration. In addition, the non-conservative nature of these tracers (with respect to their upper boundary condition) introduces the global bias (fixed nitrogen and oxygen inventory) as a useful additional constraint on model parameters. Dissolved organic phosphorus at the surface behaves antagonistically to phosphate, and suggests that observations of this tracer – although difficult to measure – may be an important asset for model calibration.
Crenças de autoeficácia de professores: um fator motivacional crítico na educação inclusiva
Authors: Bzuneck José Aloyseo 
Published: November 2017

Além de habilidades de ensino, professores devem ter crenças de autoeficácia bem desenvolvidas, que consistem nas crenças de que podem atuar com êxito até em classes com clientela diversificada. Pesquisas têm comprovado a proposta de Bandura de que professores com tais crenças mais robustas consideram que todos os alunos podem aprender e, assim, são mais comprometidos e motivados para criar condições propícias ao desenvolvimento de cada aluno em classe. Sãomais persistentes e mais resilientes após fracassos. Dados de pesquisa também têm produzido apoio à proposta de Bandura de que professores numa escola acabam por desenvolver um senso de eficácia coletiva que, quanto mais robusto, influencia cada indivíduo a ter mais persistência nas dificuldades e a ter expectativas mais elevadas quanto a seus alunos. No presente artigo, são apresentadas as condições por meio das quais são incrementadas, na Educação Inclusiva, tanto a autoeficácia como a eficácia coletiva, assim como suas consequências para os alunos.
Le tango argentin entre apprentissage et improvisation. Quel média pour quel reenactment ?
Authors: De Luca Valeria 
Published: November 2017

Inscrit en 2009 sur la liste du patrimoine culturel immatériel de l’humanité de l’UNESCO, le tango argentin est transmis par sa propre pratique caractérisée par l’improvisation de la milonga (le bal).
Avec la multiplication de traces audiovisuelles diverses — des vidéos de démonstration aux systèmes de motion capture, en passant par des sites web et des applications pour l’apprentissage de la danse —, il s’agit de comprendre les relations entre l’improvisation comme pratique fondatrice du tango et ses diffractions médiales, ainsi que le statut de ces diffractions. Quels aspects du mouvement et de la pratique restituent-elles ? Sont-elles elles-mêmes un reenactement médial se superposant à celui des corps des sujets ?
Research Ideas and Outcomes journal (R.I.O.): A novel way to make science
Authors: Hachani Samir 
Published: November 2017

Watch the VIDEO here.Peer review has been a cornerstone of science since the first scientific journals started in the middle of 17th century. It has since evolved from a case by case and non standardized process to a more regulated and organized undertaking. The period at which peer review entered its new phase is the Second World War and the extraordinary boom of scientific output that resulted from the cold war. All this output had to have a receptacle (scientific journals) but also had to be selected due to the big amount of data produced. That is when peer review became unanimously and, to some extent, uniformly implemented. It also became the unavoidable door leading to a number of advantages all researchers are looking for (promotions, funding, prize, etc.).That’s when the human component intervened and made the process a rather biased process subject to all kinds of critics. One of the main (if not the main) problem is the secrecy in which the process is undertaken and that has led to all kind of iniquitous, unjust and sometimes bizarre decisions. The process tried to inject some kind of openness (going from blind to double blind peer reviewing for example) with little results. The 90’s of the last century saw the Internet slowly becoming more and more used in everyday life and, more importantly, in the scientific and academic research. With all the problems besetting peer review ,Internet’s openness seemed as the best cure to all the grievance peer review elicited. Among the most revolutionary experiences, Faculty of 1000 (F 1000), Atmospheric Chemistry and Physics (A.C.P.), Journal of Medical Internet Research (J.M.I.R.), British Medical Journal? Electronic Transactions on Artificial Intelligence ( ETAI) and Biology Direct have introduced new ways to undertake peer review that have somehow alleviated the numerous critics. With Research Ideas Outcomes (RIO), the process enters a new era of openness as its two stages are completely open: the pre submission peer review (part 1) in which the submitter is reviewed before submission by a colleague and could even ask colleagues to help write his proposal and then open post-publication peer-review (part 2) in which the process is even more open as authors could decide what reviews are published, when and also decide to ask for an in house classic type of review done exclusively by peer reviewers from RIO or let the whole community implement a Post Publication Peer Review that could putatively last as long as the article is on the system. All the process is open in all its steps and allows novelty, among others, to recognize namely reviewers’ work, a task they have so far anonymously and without any reward of any kind. This proposal will explain in details the process and try to understand the (r)evolution this kind of process introduces to the making of science through transparency in a stage of science that has been known to be utterly secretive.

<p>A preocupação com a conformidade legislativa se mostra cada vez mais frequente em diversos setores, inclusive o setor de saúde. Empresas das áreas hospitalar e farmacêutica, por exemplo, vêm investindo de forma mais frequente<br />em medidas para se adequarem às leis e diretrizes concernentes às suas atividades. Tais providências podem ser consideradas partes de um plano que visa à adequação com as normas regulatórias. Em suma: as empresas do setor<br />de saúde estão se empenhando para adotar programas de compliance. O termo “compliance” tem sua origem na língua inglesa e significa atuar de acordo com o que foi estabelecido.<br />Essa expressão está sendo bastante utilizada ultimamente no meio empresarial, pois se trata de uma forma de diminuir os riscos existentes no âmbito de uma organização. Dentre os objetivos de um programa de compliance estão: o cumprimento às leis e aos princípios éticos que regem as boas práticas empresariais; o estímulo ao desenvolvimento de uma cultura de controles internos; assegurar que a empresa atenda a todos os requisitos dos órgãos reguladores e fiscalizadores.<br />É sabido que funcionários podem praticar atos em desconformidade com as normas que regulam a atividade da empresa e, com o objetivo de evitar a ocorrência dessas condutas, é interessante para a organização investir na<br />elaboração de um programa de compliance eficiente. Ao estabelecer um programa de conformidade efetivo, a empresa da área de saúde, setor sujeito a um ambiente regulatório bastante rígido, torna-se apta a identificar e mitigar riscos, de forma que considera-se um programa de compliance uma providência adotada para promover a sobrevivência da organização..............</p>
