Abstract

Context
Studies of the possible cardiovascular risk of testosterone treatment are inconclusive.

Objective
To determine the effect of testosterone treatment on cardiovascular biomarkers in older men with low testosterone.

Design
Double-blind, placebo-controlled trial.

Setting
Twelve academic medical centers in the United States.

Participants
In all, 788 men ≥65 years old with an average of two serum testosterone levels &lt;275 ng/dL who were enrolled in The Testosterone Trials.

Intervention
Testosterone gel, the dose adjusted to maintain the testosterone level in the normal range for young men, or placebo gel for 12 months.

Main Outcome Measures
Serum markers of cardiovascular risk, including lipids and markers of glucose metabolism, fibrinolysis, inflammation, and myocardial damage.

Results
Compared with placebo, testosterone treatment significantly decreased total cholesterol (adjusted mean difference, −6.1 mg/dL; P &lt; 0.001), high-density lipoprotein cholesterol (adjusted mean difference, −2.0 mg/dL; P &lt; 0.001), and low-density lipoprotein cholesterol (adjusted mean difference, −2.3 mg/dL; P = 0.051) from baseline to month 12. Testosterone also slightly but significantly decreased fasting insulin (adjusted mean difference, −1.7 µIU/mL; P = 0.02) and homeostatic model assessment‒insulin resistance (adjusted mean difference, −0.6; P = 0.03). Testosterone did not change triglycerides, d-dimer, C-reactive protein, interleukin 6, troponin, glucose, or hemoglobin A1c levels more than placebo.

Conclusions and Relevance
Testosterone treatment of 1 year in older men with low testosterone was associated with small reductions in cholesterol and insulin but not with other glucose markers, markers of inflammation or fibrinolysis, or troponin. The clinical importance of these findings is unclear and requires a larger trial of clinical outcomes.

Published: December 2017

Breast and endometrial cancer are the most common types of female cancers, but the incidence of both of these malignancies in a single patient is a rare event. Multiple primary malignancy has been increasingly reported over the past decade, and double primary cancer is considered as the most common type. In this study, we present a 53-year-old woman with synchronous primary malignancy of breast and endometrium. This patient had a history of breast and endometrial cancer in her family. Mammography and chest CT of the patient revealed a mass in the right breast and left supraclavicular region. However, the patient did not want to initiate treatment. Subsequently, the patient returned with a chief complaint of persistent abnormal vaginal bleeding. Abdominopelvic CT scan of the patient revealed a huge soft tissue mass in the pelvic cavity. She underwent hysterectomy, and pathology revealed endometrioid carcinoma, which had invaded the full thickness of uterine wall. Since this type of malignancy is rare and several risk factors are associated with it, it is worth being considered by clinicians when making decisions about screening or strategy for prevention.
La comunidad andina: las fuerzas centrífugas ejercidas por los Estados Unidos sobre un régimen comercial en formación
Authors: Prado Espinosa María Mercedes 
Published: December 2017

La región andina se compone de cuatro países latinoamericanos: Bolivia, Colombia, Ecuador y Perú, unificados en la asociación regional: Pacto Andino, suscrito en 1969, que se redefine como la Comunidad Andina de Naciones (can) en 1996. Al cabo de más de 45 años de existencia se requiere comprender las causas profundas de los resultados económicos de la región andina: un comercio intrarregional que no registra el despegue esperado, y un comercio con países por fuera del perímetro regional, dominado por las materias primas, a pesar de las recurrentes tentativas por instaurar programas regionales de desarrollo industrial. El presente artículo propone estudiar el caso de las relaciones económicas y políticas de los países miembros de la can con actores hemisféricos relevantes, en este caso con los Estados Unidos. Se propone como explicación de los escasos avances de la can en materia económica y comercial, la configuración de los principales mercados de exportación que arrastran y determinan las estructuras productivas de las economías andinas, en detrimento del proceso de una integración económica regional profunda.
Comercio y trabajo: utilidades subjetivas y derechos humanos en la negociación de acuerdos comerciales – los casos de Colombia y Perú
Authors: Fernández Dusso Juan José 
Published: December 2017

En 2004, los gobiernos de Perú y Colombia iniciaron, conjuntamente con Ecuador, la negociación de un acuerdo de libre comercio con el Gobierno de Estados Unidos. Retirado Ecuador del proceso y desligadas las negociaciones de los dos países restantes, el documento negociado entre Perú y Estados Unidos fue ratificado en 2006 y 2007 por los congresos de cada uno respectivamente. Por su parte, el negociado por Colombia vio prolongada su revisión y aprobación por parte del congreso norteamericano. ¿Qué explica las mayores dificultades para la aprobación del acuerdo entre Colombia y Estados Unidos? Para el periodo en revisión, se encuentra una mayor oposición conjunta al acuerdo colombiano que condiciona su aprobación a la solución de asuntos relacionados con derechos fundamentales de los trabajadores. Pero la divergencia se explica aquí tras un análisis de la respuesta del Gobierno colombiano a la presión trasnacional, que devela una ineficaz estrategia del expresidente Uribe condicionada por la incompatibilidad percibida entre las demandas de la oposición y su política de seguridad interna.
Round Table: Target Groups, Users, Followers, Fans – The Nature and Potential of Social Data in Archaeology

Published: December 2017

At the 21st Cultural Heritage and New Technologies conference (CHNT), which took place from Novembe 16th to 18th 2016 in Vienna, Austria, Carmen Löw organized a round table to discuss first experiences with social data from the use of social media in archaeology. The participants presented two Facebook accounts and one weblog owned by a UNESCO World Heritage, a research project and a private company. So far, social data has received too little attention in archaeology. Regardless of the limitations encountered with a user group with special age, sex and other regulations, social data helps us to understand at least a part of our stakeholders better and to adjust the information we offer in social media to their interests. To communicate in a professional manner, it is mandatory to understand who is on the receiving end of the information transportation process. Tools, all well-known and widely used in the world of economics, are often not affordable for scientific research in humanities and so we could mostly only guess who might be listening to us. Since archaeology is widely present in the internet, and since there are Facebook-accounts, websites and weblogs, it is now possible for us to get some reliable information about our followers and supporters. In this article, we provide basic information on communication, with a special focus on communication in the archaeological field, as well as figures on the current use of the Internet. We present data, possibilities for their interpretations and general observations on users, followers and fans in selected tools from the three examples mentioned above.
Synthesis, characterization, second and third order non-linear optical properties and luminescence properties of 1,10-phenanthroline-2,9-di(carboxaldehyde phenylhydrazone) and its transition metal complexes

Published: December 2017

AbstractThe requirement for materials which exhibit good second and third order non-linear optical properties and also for materials which could sense metals in trace quantities has kindled renewed investigations. Organometallics and coordination compounds show a lot of promise as new NLO materials combining the variety of organic moieties with the strength and variable oxidation states of metals. Especially ligands which selectively detect industrial pollutants like Cd and biologically significant metals like Zn are necessary. In the current work the ligand 1,10-phenanthroline-2,9-di(carboxaldehyde phenylhydrazone) (L) and its Ni2+, Co2+, Fe2+, Zn2+, Cd2+ and Ir3+ complexes were synthesized. These were characterized by UV-Vis, FT-IR, 1H NMR, MS and CHN microanalysis techniques. The complexes were shown to have the formula [ML]2+. The second and third order NLO of the ligand and its complexes were recorded These new compounds were found to have same order of third order nonlinear optical susceptibility as that of CS2 and their second hyperpolarizability was an order of magnitude greater than that of C60. Furthermore the ligand also displays selective luminescence sensing of metals ions Fe2+ and Ir3+ even in the presence of other metal ions.
The nurse-patient communication: voices from nursing students
Authors: Chan Zenobia C.Y. , Lai Claudia K.Y. 
Published: December 2017

Abstract

Background:
Effective communication skills have been found to be one of the pivotal factors in building positive interpersonal relationships. Little is known about nursing undergraduates’ perspectives on communicating with patients.

Objective:
This study aimed to explore nursing students’ perspectives and experiences of nurse-patient communication in their clinical placement.

Methods:
The participants included 21 second-year undergraduates and 21 first-year master’s students. Interviews were conducted in Cantonese and then transcribed in Chinese and translated into English. A content analysis approach was adopted to analyze the data.

Results:
Five themes emerged from the interview data. ‘The necessity of nurse-patient communication’ reveals why the students valued nurse-patient communication. ‘The conversation contents’ describes the content of the conversations that students typically had with patients. The third theme is ‘self-reflection on the nurse-patient communication’. The last two themes, ‘the communication pattern in different hospital settings’ and ‘the obstacles impeding nurse-patient communication’, are about the students’ communication styles in different hospitals and the barriers they encounter.

Discussion:
To improve students’ communication skills, educators and clinical staff should listen to students, enhance students’ reflective skills and strengthen their confidence.

Conclusion:
Through understanding students’ difficulties in the nurse-patient communication experience and the skills that they lack, educators can provide them with helpful recommendations to improve their communication skills in clinical practice.

Practice implications:
The results of this study reveal that students’ nurse-patient communication skills need to be improved.
The Tarunya Project’s efforts to improve the quality of adolescent reproductive and sexual health services in Jharkhand state, India: a post-hoc evaluation
Authors: Barua Alka , Chandra-Mouli Venkatraman 
Published: December 2017

Abstract
Following the International Conference on Population and Development Adolescent Reproductive and Sexual Health (ARSH) was recognized as a top development priority in India’s National Population Policy 2000. In 2006 a separate ARSH strategy was articulated within the National Rural Health Mission. In Jharkhand, one of the poorest and least developed states in India, in 2008 the state government launched a Tarunya Project in collaboration with EngenderHealth. The project provided cascading ARSH training to government staff at secondary care facilities and strengthened outreach activities to enhance community engagement. After 5 years of implementation, the project was evaluated by a team from the World Health Organization. The evaluation found that the project provided training and ongoing backstopping support to strengthen the ARSH readiness of health facilities. The project’s intervention efforts contributed to improvement in quality and initial use of ARSH services. The performance of health facilities was appreciated by clients. But there was little correspondence between the project’s monitoring and the period of exposure of the facilities to the project’s interventions and service quality. The evaluation also showed that handholding and backstopping by the project were still very much needed.

Published: December 2017

Abstract
Experimental investigation was conducted on the thermal performance and pressure drop of a convective cooling loop working with ZnO aqueous nanofluids. The loop was used to cool a flat heater connected to an AC autotransformer. Influence of different operating parameters, such as fluid flow rate and mass concentration of nanofluid on surface temperature of heater, pressure drop, friction factor and overall heat transfer coefficient was investigated and briefly discussed. Results of this study showed that, despite a penalty for pressure drop, ZnO/water nanofluid was a promising coolant for cooling the micro-electronic devices and chipsets. It was also found that there is an optimum for concentration of nanofluid so that the heat transfer coefficient is maximum, which was wt. % = 0.3 for ZnO/water used in this research. In addition, presence of nanoparticles enhanced the friction factor and pressure drop as well; however, it is not very significant in comparison with those of registered for the base fluid.
Three-dimensional nanoscale imaging by plasmonic Brownian microscopy

Published: December 2017

AbstractThree-dimensional (3D) imaging at the nanoscale is a key to understanding of nanomaterials and complex systems. While scanning probe microscopy (SPM) has been the workhorse of nanoscale metrology, its slow scanning speed by a single probe tip can limit the application of SPM to wide-field imaging of 3D complex nanostructures. Both electron microscopy and optical tomography allow 3D imaging, but are limited to the use in vacuum environment due to electron scattering and to optical resolution in micron scales, respectively. Here we demonstrate plasmonic Brownian microscopy (PBM) as a way to improve the imaging speed of SPM. Unlike photonic force microscopy where a single trapped particle is used for a serial scanning, PBM utilizes a massive number of plasmonic nanoparticles (NPs) under Brownian diffusion in solution to scan in parallel around the unlabeled sample object. The motion of NPs under an evanescent field is three-dimensionally localized to reconstruct the super-resolution topology of 3D dielectric objects. Our method allows high throughput imaging of complex 3D structures over a large field of view, even with internal structures such as cavities that cannot be accessed by conventional mechanical tips in SPM.

Religious Congregations and Poverty Alleviation in the Age of New Public Governance
Authors: Scott Marquisha Lawrence , Cnaan Ram A. 
Published: December 2017

AbstractWe discuss the implications of the new public governance and its impact on the social and economic outcomes of those experiencing poverty. As members of civil society, religious congregations are actively engaged in supporting people living in poverty with short-term responses. Addressing the societal focus on economic justice and the theological traditions of four world religions, this paper seeks to encourage religious congregations into innovative, actionable responses that help to offer long-term responses that align with poverty alleviation. We propose two approaches—community development and financial development— that serve as models for religious congregations interested in alleviating poverty.
Responsible Investment: Taxes and Paradoxes
Authors: Knuutinen Reijo , Pietiläinen Matleena 
Published: December 2017

Abstract
Taxes have become an issue of corporate social responsibility (CSR), but the role of taxation is to some extent an ambiguous and controversial issue in the CSR framework. Similarly, another unclear question is what role investors who are committed to sustainable and responsible investment (SRI) see taxes as having on their environmental, social, and governance (ESG) agenda. Corporate taxes have an inverse relationship with the return of the investors: taxes paid directly affect what is left on the bottom line, reducing the return of investors. However, investors are now more aware of tax-related risks, which can include different forms of reputation risk. Corporate tax planning may increase the returns, but those increased returns are riskier. This study focuses particularly on the relationship between SRI and taxation. We find that tax matters are considered to be on the ESG agenda, but their role and significance in the ESG analysis is unclear.

Bryophyte Records from the Eastern Nigerian Highlands
Authors: Ezukanma Izuchuk O. , Ogundipe Oluwatoyin T. , Nodza George I. , Pócs Tamás 
Published: December 2017

Abstract
A preliminary inventory of the eastern Nigerian highlands yielded 27 bryophyte species (5 liverworts, 22 mosses), including 13 species new for the country (2 liverworts and 11 mosses). The large percentage of new national records (ca 52%) indicates that the eastern Nigerian highland has rich bryophyte diversity and is undercollected. A more detailed inventory of the region using more rigorous sampling protocols is recommended.
Sprachaufgabe, Sprachwechsel und „Sprachnischen“. Einige Überlegungen zum Sprachtod am Beispiel des Sassaresischen
Authors: Linzmeier Laura 
Published: December 2017

AbstractThe following contribution deals with the research field of language death, that is, language abandonment, language shift, and “niches of language use”. It proposes a number of important theoretical and empirical clarifications, resulting from an extended fieldwork- and corpus-based analysis of the ethnolinguistic situation of Sassarese, a transitional variety between Sardinian and Corsican in the North-West of Sardinia. Sassarese is nowadays considered to be “definitely endangered” (Moseley 32010), as its domains are limited to a few social and situational ‘niches’. This contribution intends to demonstrate the extent to which external setting and speech behaviour are interrelated and how this interaction influences the vitality of the idiom.
Lust, Desire, Hope. Dante and the Problem of Love (Inf. V; Purg. XVII–XVIII; Purg. XXVI)
Authors: Gubbini Gaia 
Published: December 2017

AbstractThe article reconstructs the ‘strategy’ used by Dante in the Commedia for solving the problem of love: moving from lust (Inf. V), to the possibility of controlling natural desire through free choice (Purg. XVII-XVIII), to the role of hope in the pursuit of divine love, abandoning cupiditas and embracing caritas (Purg. XXVI). This trajectory is identified through lexical, rhyme-related, and thematic connections. It begins and ends with the first and the last sinners Dante encounters during his journey: Francesca and Arnaut Daniel - both condemned for their lust. The article also explores the reflections of Dante on the previous romance literature dealing with love, providing in particular a more convincing explanation of the presence of Arnaut Daniel - whose courtly love poetry was grounded on the theme of hope - at the end of Purgatory, the supernatural realm of Hope. Moreover, the investigation is set in the context of Dante’s philosophical and theological background - confirming with new elements the coexistence of his Augustinian imagery with the Thomist moral structure of the Commedia.
Uma poética da arqueologia no romance Céu subterrâneo, de Paulo Rosenbaum
Authors: Nascimento Lyslei 
Published: December 2017

AbstractPaulo Rosenbaum’s novel Céu Subterrâneo is narrated by Adam Mondale, a writer, psychologist, animal behaviorist, and collector of cameras. His journey to Israel in search of a particular negative turns into an encounter with a mythical and mystical past, in the process of which Mondale becomes a researcher of himself and his origins, while making the reader his accomplice. As Walter Benjamin has argued, memory itself is not an instrument for exploring the past, but rather represents various strata through which one must pass: anyonewho wishes to approach previous experiences must carefully uncover, almost archeologically unearth it. Employing a Benjaminian strategy in his multi-layered text, Rosenbaum has his protagonist face his multifaceted self in an excavation of his past, straining to meticulously inventory and arrange his findings. At the metalevel, Rosenbaum’s archeological poetics inscribe his novel into a contemporary tradition of encyclopedic narratives.
