Authors: Affleck William , Oliffe John , McKenzie Sarah , Ridge Damien , Jenkins Emily , Broom Alex
Published: May 2020

Like many human experiences, traumatic stress is highly gendered. Over the past several decades, a substantial number of empirical studies have explored ethical issues in traumatic stress research. However, these studies have typically reported female samples or failed to account for the influence of gender in their analyses of mixed-sex samples. By extension, ethical issues that are relevant to male participants in traumatic stress research are poorly understood. After briefly exploring why the vulnerabilities of male participants are under-explored in traumatic stress research, this article highlights many ethical issues that are important to address when men participate in traumatic stress research, concluding with some suggestions for how these might be taken up to advance the field.
Considerations of Visual Quality in Ocular Surgery as Presented at Dry Eye University
Authors: Bowden Frank
Published: May 2020

Visual quality may be described as the visual experience which reflects the optimal optical efficiency of the eye. Patients undergoing ocular surgery expect improvement in visual acuity. Ocular surgeons typically aim to improve best-corrected visual acuity. Refractive surgeons, on the other hand, strive to improve uncorrected visual acuity. It is not uncommon that patients with excellent corrected visual acuity following surgery may be dissatisfied with visual quality which is less than anticipated due to unexpected visual disturbances. These visual phenomena may include ghosting, glare, halos, reduced contrast sensitivity, and visual fluctuation.

Published: May 2020

Special access techniques during percutaneous nephrolithotomy (PCNL) are indicated for challenging stones. Various techniques have been described to inferiorly displace the kidney to facilitate optimal percutaneous access whilst minimizing thoracic complications associated with the supracostal approach.

We describe our institution’s technique of using a ureteric balloon catheter to inferiorly distract and immobilize the kidney (UBC Technique) to achieve the optimal calyceal access infracostally during PCNL. This permits effective and safe access in a single puncture whilst additionally stabilizing the renal unit during respiration and reducing the skin-to-calyceal distance by mobilizing the desired calyx in line with the axis of the puncture needle. We reviewed the literature regarding alternative inferior renal displacement techniques permitting infracostal approaches.

From May 2012 to October 2017 150 PCNLs were performed in our institution. Out of these, the UBC technique was used in 18 cases during both prone and supine PCNLs. In all cases, the UBC technique was used successfully to access the most desirable calyx. No complications associated with renal distraction were reported. Post operatively, 1 patient required a blood transfusion, 1 patient had a pyrexia of >38 degrees resulting in a longer admission and 1 patient developed sepsis requiring HDU admission for monitoring only. 15 out the 18 patients had complete stone clearance from their PCNL.

The UBC technique provides a safe alternative to the supracostal approach in percutaneous renal surgery. It is less traumatic than alternative infracostal access techniques and has a very short learning curve.

Background and Objective

To assess the feasibility and safety of performing bipolar transurethral enucleation of the prostate (BIPO-LEP) with a new generation of bipolar electrosurgical and morcellator system.

Material and Methods

Forty-five consecutive patients scheduled for endoscopic surgery for benign prostatic obstruction were pro-spectively recruited. BIPOLEP was performed with the use of the third generation Karl Storz AUTOCON III 400 and morcellator unit. All patients had a trial without a catheter on Day-1 after surgery. Demographical, preoperative, intraoperative and follow-up data up to 3 months post-surgery were collected and analyzed.

Results

Between May 2018 and April 2019, 45 consecutive patients underwent BIPOLEP in our institution were prospectively recruited for this study. The mean age was 76 years old. Thirty-four patients (75.6%) were in refractory retention or obstructive uropathy. The mean enucleation efficiency was 1.76 grams per minute of enucleation time (SD = 0.7 gram per minute). The mean bladder irrigation and catheterization times were 5.3 hours and 20.7 hours respectively. Only one patient failed voiding trial on Day-1 after surgery. The postoperative Day-1 discharge rate was 73.3% (n = 33). The median length of hospital stay was 1 day. No patient required clot evacuation or blood transfusion. Seven patients (15.6%) were readmitted within thirty days postoperatively for complications, due to hematuria (8.9%, n = 4) and febrile urinary tract infection (6.7%, n = 3). Nevertheless, none was readmitted for acute urinary retention.

Conclusion

The use of a new generation of bipolar electrosurgical and morcellator unit for BIPOLEP was safe and the majority could be discharged without catheter within one day after surgery.

Published: May 2020

La pandemia por SARS-Cov-2, ha tomado gran relevancia por su impacto en los diversos sistemas de salud en el mundo. Inicialmente solo se contemplaba la importancia de los síntomas respiratorios y la fiebre; sin embargo, a diario tenemos más reportes y publicaciones sobre la relevancia que está teniendo en el sistema digestivo, ya que algunos pacientes informan síntomas gastrointestinales como diarrea, vómito y dolor abdominal. Los estudios han identificado el ARN del SARS-CoV-2 en muestras de heces de pacientes infectados, en las que se encontró que su receptor que es el de la enzima convertidora de angiotensina 2 (ECA2) se expresaba altamente en las células epiteliales gastrointestinales. Esto sugiere que el SARS-CoV-2 puede infectar activamente y replicarse en el tracto gastrointestinal. Esto tiene implicaciones importantes para el tratamiento de la enfermedad, la transmisión y el control de infecciones. En pacientes con patologías crónicas como la enfermedad inflamatoria intestinal (EII), se han generado gran cantidad de preguntas e incertidumbres ante la presencia de COVID-19 junto con las implicaciones que pueden tener tanto en la severidad de los síntomas, como en la descompensación de la patología de base y en la continuidad del tratamiento inmunosupresor.

El pasado mes de diciembre surgió en Wuhan, China, el SARS-CoV-2, un nuevo coronavirus productor de la coronavirus disease (COVID-19), que al 15 de abril de 2020 ha infectado a más de 2 000 000 de personas y ha causado 128 833 muertes en el mundo. Por la forma de transmisión del SARS-CoV-2, las salas de endoscopia y los procedimientos endoscópicos son una fuente de fácil diseminación, debido a que cumple con las características de un ambiente contaminado para los pacientes y el personal asistencial que participa en los procedimientos endoscópicos. Por esta razón, es de gran importancia establecer medidas dentro de las unidades de endoscopia para prevenir y disminuir el riesgo de propagación de esta infección, por medio de la creación de un entorno seguro que proteja a los pacientes y al personal de salud. Se realizó una búsqueda en Pubmed con los siguientes términos: (“COVID-19” OR “coronavirus” OR “SARS-Cov-2”) y (“gastrointestinal” OR “transmission” OR “intestinal” OR “digestive” OR “endoscopy” OR “esophagogastroduodenoscopy” OR “colonoscopy”). El grupo de gastroenterología de nuestra institución considera que todos los pacientes llevados a procedimientos endoscópicos deben ser catalogados de alto riesgo, por lo cual presenta las recomendaciones que todo el personal asistencial de las unidades de endoscopia debe tener en cuenta para disminuir el riesgo de contagio.

Published: May 2020

La enfermedad por coronavirus (COVID-19) se convirtió en una pandemia con implicaciones clínicas y emocionales, a veces invisibles para los gastroenterólogos. Aunque morir es parte de la vida, el riesgo para algunos médicos puede ser mayor. Específicamente, los gastroenterólogos nos vemos afectados por el temor a reiniciar nuestras consultas y procedimientos endoscópicos. En medio de un mar de información —incluso con contradicciones entre diferentes expertos—, seguir los lineamientos de las Asociaciones Colombianas del Aparato Digestivo podría ayudar a tranquilizar a los médicos y pacientes. Aunque las patologías seguirán apareciendo, el miedo de la población a contagiarse puede generar consecuencias como el retraso en el tratamiento de un cáncer de vías digestivas. El autocuidado físico mediante estrategias de protección y el cuidado emocional son clave para ayudar a nuestro sistema inmunológico. Adaptarnos a funcionar en medio de la pandemia por medio de la teleorientación en plataformas digitales es una forma creativa de disminuir la angustia colectiva.

This article investigates the Financial Market Leagues (LMF) as interstitial organizations through the lens of the Theory of Academic Capitalism. A case study was conducted based on a LMF in a Brazilian public university (LMF-Unab). Data collection involved the LMF’s National Council, business press, institutional pages of the LMFs and the internships coordination of the university studied. Moreover, 82 questionnaires were applied to members of 29 LMFs and the founders of the LMF-Unab were interviewed. The results revealed that 70.1% of respondents are between 20-23 years old; 81% attended private high school; 48% attend Engineering courses. LMFs operate within universities legitimizing narratives and metrics typical of a financialization process, which is illustrated by iconic figures of the discourse of meritocracy and the aggressive culture of results, such as Jorge Paulo Lemann, among other respondents' sources of inspiration. This paper addresses the literature gap regarding the understanding of student organizations as actors of academic capitalism, often portrayed as passive agents in this process, but who are actually active and benefit from it.
Construcción identitaria de jóvenes infractores durante la implementación de medidas “alternativas” en Argentina
Authors: Fernández Mariana Cecilia
Published: May 2020

El presente artículo analiza el modo en que se construye la identidad de jóvenes infractores de la ley penal en el contexto de la implementación de medidas alternativas a la privación de libertad en la Argentina contemporánea. A más de diez años de la sanción de la ley de Promoción y Protección de los derechos del niño, en 2004, nos proponemos reflexionar sobre los procesos de transformación o aggiornamiento en la concepción del joven infractor y su vinculación con las acciones pertinentes de desarrollar en un centro de Referencia de la Provincia de Buenos Aires. Algunos resultados del estudio nos permiten afirmar que, en el marco de la intervención alternativa a la privación de libertad, la identidad de los jóvenes se construye, en forma reintegrativa y en forma estigmatizante, intermitentemente, a partir de discursos de diferentes niveles de moralidad.

En busca de la representación política: el partido mapuche Wallmapuwen en Chile
Authors: Tricot Salomon Víctor , Bidegain Ponte Germán
Published: May 2020

Este artículo aborda la actuación en política convencional por parte del movimiento mapuche, mediante el estudio del partido Wallmapuwen, con más de 10 años de existencia, pero sólo reconocido electoralmente por el Estado chileno entre 2016 y 2017. A través de este caso analizamos cómo operan los mecanismos causales que dificultan el surgimiento de un partido étnico en contextos desfavorables como el chileno. Además, damos cuenta de la participación en política de esta organización durante los años en que no fue legalmente reconocida. El caso analizado demuestra la necesidad de repensar la definición de partido étnico para tomar en cuenta organizaciones que a pesar de no obtener el reconocimiento legal operan dentro de la política electoral nacional mediante diversas estrategias. En consecuencia, presentamos una definición de partido étnico novedosa que incorpora esta situación. Nuestro estudio es de carácter cualitativo sostenido mediante análisis de datos secundarios, observación y entrevistas semiestructuradas.

La debilidad del mercado de trabajo es uno de los rasgos que distinguen a la fase recuperación económica que sucedió a la Gran Recesión, reconocible entre otros aspectos en el lento descenso de la tasa de desempleo, la caída de la participación económica y de las tasas de empleo poblacional. Para valorar la situación de los inmigrantes latinoamericanos, en dicho contexto se emprende un análisis multivariado de la probabilidad de pasar del empleo a la inactividad económica en cuatro momentos: precrisis (2007), crisis (2009) y crecimiento (2014 y 2016), ajustados de manera independiente para hombres y mujeres. Los resultados corroboran el incremento general de dicha probabilidad, entre 2007 y 2016, la mayor vulnerabilidad de los inmigrantes latinoamericanos a los altibajos del ciclo y un balance en conjunto menos favorable para la fuerza de trabajo femenina que masculina en la post recesión.
Imaginarios de la robotización: la automatización desde la perspectiva del empleado
Authors: Inzunza Acedo Beatriz Elena , Wright Claire , Ghys Tuur , Cools Pieter
Published: May 2020

En el contexto de la cuarta revolución industrial se investigaron las percepciones de algunos empleados con mayor riesgo de desocupación tecnológica en aras de la robotización. Se organizaron grupos de discusión con obreros del sector automotriz, químico, agentes de centros telefónicos y empleadas domésticas. Los principales hallazgos indican que la tecnología es deseable cuando sirve para apoyar el trabajo del empleado, mas no para reemplazarlo. Los participantes expresan su pesimismo respecto a posibles políticas públicas que pudieran compensar su desempleo, así como de la consideración de los empresarios para sustituir a los empleados por máquinas. El valor de este trabajo radica en el abordaje de un fenómeno actual que investiga la opinión de actores que, si bien son los más afectados, no influyen en la toma de decisiones de los procesos de automatización.

Kavramsal bir çalışma olan bu makale konuyla ilgili olan dış yardım, resmi kalkınma yardımları, kamu kalkınması yardımları, insani yardım, afet ve acil durum yardımları, insani diplomasi, afet diplomasisi gibi kavramların tanımlamalarını yaparak, bu kavramların akademik literatürde ve pratikte kullanımlarındaki tanımsal sorunların çözümüne katkıda bulunmayı amaçlamaktadır. Çizilen kavramsal çerçevede Türkiye COVID-19 pandemisi sırasında geleneksel olarak kamu kalkınması ve insani yardım yaptığı en az gelişmiş ve gelişmekte olan ülkelerin dışında, afet yardımları kavramı tanımına uygun olarak COVID-19’la mücadelede kendi kapasitelerinin üzerinde bir insani krizle karşı karşıya kalan gelişmiş ülkelere de yardımlarda bulunmuştur.
El principio de objetividad en el procedimiento administrativo
Authors: Míguez-Macho Luis
Published: May 2020

El presente trabajo estudia las relaciones entre el principio de objetividad de la Administración y el procedimiento administrativo en el Ordenamiento jurídico español. Para ello se parte de una reflexión general sobre el significado que tiene la procedimentalización de la actuación administrativa como exigencia derivada del principio de objetividad, puesto que tradicionalmente se ha venido considerando que la propia existencia del procedimiento administrativo es, en buena medida, una consecuencia de dicho principio. Sentada esta base, se analiza la imparcialidad de los responsables de la tramitación y resolución del procedimiento como presupuesto de la objetividad, las principales técnicas de integración de intereses públicos y privados en el y los informes técnicos y jurídicos y otras técnicas de adquisición de los fundamentos objetivos de la resolución del procedimiento.

Reduction of carbon impurities in aluminium nitride from time-resolved chemical vapour deposition using trimethylaluminum
Authors: Rouf Polla , Sukkaew Pitsiri , Ojamäe Lars , Pedersen Henrik
Published: May 2020

Aluminium nitride (AlN) is a semiconductor with a wide range of applications from light emitting diodes to high frequency transistors. Electronic grade AlN is routinely deposited at 1000 °C by chemical vapour deposition (CVD) using trimethylaluminium (TMA) and NH3 while low temperature CVD routes to high quality AlN are scarce and suffer from high levels of carbon impurities in the film. We report on an ALD-like CVD approach with time-resolved precursor supply where thermally induced desorption of methyl groups from the AlN surface is enhanced by the addition of an extra pulse, H2, N2 or Ar between the TMA and NH3 pulses. The enhanced desorption allowed deposition of AlN films with carbon content of 1 at. % at 480 °C. Kinetic- and quantum chemical modelling suggest that the extra pulse between TMA and NH3 prevents re-adsorption of desorbing methyl groups terminating the AlN surface after the TMA pulse.
Molecular Embroidering of Graphene

In the present work, we developed for the first time a practical approach to achieve multiply pattterning of graphene in a way of “molecular graphene embroidery” (as analogy to the well-known fabric embroidery existing in macroscopic world) by manipulating the graphene chemistry to generate regular multiply functionalized patterns consisting of concentric regions of covalent addend binding. Molecular graphene embroidery towards these spatially resolved 2D-hetero-architectures was accomplished by repetitive electron-beam lithography (EBL)/reduction/covalent-binding sequences starting with polymethyl methacrylate (PMMA) covered graphene deposited on a reactive SiO2/Si substrate, a key factor for strain-free antaratopic additions.
Fixing the housing crisis
Authors: Wilson Nick
Published: May 2020

This article looks at the intergenerational issues associated with housing in New Zealand. Election year is again upon us (Covid-19 permitting) and, with the problems surrounding KiwiBuild, housing affordability is under the spotlight. It is no secret that New Zealand has a housing affordability problem and many causes are feeding this.

Two of these causes – capital taxation inconsistencies and infrastructure issues – will be the focus of this article. Inconsistencies in the taxation of capital income are a major source of the problem, causing intergenerational transfers from younger to older generations. A land tax is a possible solution. Complementary policies targeted at addressing infrastructure bottlenecks also have an important role to play.
Blockchain in Aotearoa
Authors: Jenkins Kevin
Published: May 2020

Blockchain technology has been moving beyond cryptocurrency into new areas internationally, with substantial investment from both the private sector and government, including private sector projects in Aotearoa. However, there is not yet clear evidence of successful use cases at scale. The technology offers important benefits through creating tamper-proof records of transactions, and major drawbacks of public networks like bitcoin, such as massive power consumption, do not seem to apply to regulatory uses based on private blockchain networks. But there is debate over whether the technology is as secure as its proponents claim. In exploring blockchain’s potential, regulatory designers will want to carefully consider more conventional alternatives such as distributed databases.
The Global Plastic Pollution Crisis
Authors: Farrelly Trisia , Green Laura
Published: May 2020

The management of plastic waste is a global problem which currently lacks a global solution. As one of the highest per capita producers of household waste in the developed world, New Zealand has a key role to play in addressing the plastics crisis at multiple levels of governance. This article analyses the various policy options available to the New Zealand government and offers a series of recommendations, including prioritising policy and investment at the top of the waste hierarchy (refuse, rethink, redesign, reduce and reuse); linking plastic waste to toxicological risk and commitments to carbon reduction targets; implementing global commitments domestically; and supporting a proposed international legally binding agreement that captures the full lifecycle of plastics and regulates the transboundary flows of plastic pollution.
TRATAMENTO DA PSORÍASE EM IDADE PEDIÁTRICA – PARTE II: FOTOTERAPIA E TRATAMENTO SISTÉMICO
Authors: Cruz Maria João , Magina Sofia , Boudrier Teresa , Azevedo Filomena
Published: May 2020

A psoríase é uma doença inflamatória crónica, multissistémica e imunologicamente mediada. Cerca de um terço dos adultos acometidos refere início da doença antes dos 16 anos de idade, representando aproximadamente 4% de todas as dermatoses observadas em idade pediátrica. O diagnóstico precoce e a instituição de terapêutica adequada desempenham um papel fundamental na diminuição do impacto físico, emocional e social, bem como das co-morbilidades associadas. Na maioria dos casos a doença é limitada, sendo a terapêutica tópica suficiente para o seu controlo. Contudo, uma minoria das crianças apresenta um quadro grave e rapidamente progressivo que obriga à instituição de medicação sistémica. O recurso a estas terapêuticas, tanto tópicas como sistémicas, é limitado pelos riscos de toxicidade, pela baixa aceitação e ausência de estudos que validem e orientem a utilização da maioria destes fármacos em crianças. Este é o segundo de 2 artigos onde se pretendem rever as opções terapêuticas tópicas (Parte I) e sistémicas (Parte II) disponíveis, assim como a sua eficácia e segurança em idade pediátrica.
