Objective:
Positron emission tomography (PET) using 18F-fludeoxyglucose (18F-FDG) is an established imaging modality for tumor staging in patients with non-small cell lung cancer (NSCLC). There is a growing interest in using 18F-FDG PET for therapy response assessment in NSCLC which relies on quantitative PET parameters such as standardized uptake values (SUV). Different reconstruction algorithms in PET may affect SUV. We sought to determine the variation of SUV in patients with NSCLC when using ordered subset expectation maximization (OSEM) and block sequential regularized expectation maximization (BSREM) in latest-generation digital PET/CT, including a subanalysis for adenocarcinoma and squamous cell carcinoma.

Methods:
A total of 58 patients (34 = adenocarcinoma, 24 = squamous cell carcinoma) who underwent a clinically indicated 18F-FDG PET/CT for staging were reviewed. PET images were reconstructed with OSEM and BSREM reconstruction with noise penalty strength β-levels of 350, 450, 600, 800 and 1200. Lung tumors maximum standardized uptake value (SUVmax) were compared.

Results:
Lung tumors SUVmax were significantly lower in adenocarcinomas compared to squamous cell carcinomas in all reconstructions evaluated (all p &lt; 0.01). Comparing BSREM to OSEM, absolute SUVmax differences were highest in lower β-levels of BSREM with + 2.9 ± 1.6 in adenocarcinoma and + 4.0 ± 2.9 in squamous cell carcinoma (difference between histology; p-values &gt; 0.05). There was a statistically significant difference of the relative increase of SUVmax in adenocarcinoma (mean + 34.8%) and squamous cell carcinoma (mean 23.4%), when using BSREM350 instead of OSEMTOF (p &lt; 0.05).

Conclusion:
In NSCLC the relative change of SUV when using BSREM instead of OSEM is significantly higher in adenocarcinoma as compared to squamous cell carcinoma.

Advances in knowledge:
The impact of BSREM on SUV may vary in different histological subtypes of NSCLC. This highlights the importance for careful standardization of β-value used for serial 18F-FDG PET scans when following-up NSCLC patients.

Published: January 2019

Background: Polycystic Ovarian Syndrome (PCOS) is the most common endocrinopathy in women of reproductive age, affecting 5-20% of women worldwide. Hyperandrogenism, as the primary characteristic of PCOS, is not always present in every patient. The hyperandrogenic phenotype of PCOS patients is influenced by both hormonal and metabolic dysfunctions. Therefore, this study aims to determine the correlation between hormone profile, lipid profile, and clinical profile with free testosterone index in subjects with PCOS. Methods: This prospective cross-sectional study was conducted in the Dr. Cipto Mangunkusumo General Hospital between July 2014 and December 2016. The study involved 76 women with PCOS, who were classified into 2 subgroups: 39 subjects in the hyperandrogenism group and 37 subjects in the non-hyperandrogenism group. Each subject underwent physical examination, blood sample collection, and USG examination. Bivariate analysis was done using independent t-tests and Mann Whitney U-tests, while multivariate analysis was done using logistic regression. Results: Triglyceride and testosterone level showed weak (r = 0.232, p = 0.044) and moderate (r = 0.460, p ¡ 0.001) positive correlation with FTI, while SHBG level showed moderate negative correlation (r = -0.483, p ¡ 0.001). Triglyceride was also found to be determinant of hyperandrogenism condition in PCOS patient (OR 0.02, 95% CI 0.00–0.04, p = 0.013). However, there was no significant difference observed between FGS and hyperandrogenism (p = 0.43). Conclusions: Triglycerides, testosterone, and SHBG were associated with hyperandrogenism in PCOS patients, while FGS showed no such association.

Background: Endometriosis is one of the most common conditions causing infertility and an indication to undergo in vitro fertilization (IVF). High apoptosis rate and oxidative stress in patients with endometriosis are believed to negatively affect the IVF success rate. However, there have been conflicting results on the effect of endometriosis on IVF success, and there have been limited studies that directly assess endometriosis and its effect on oocyte quality. This study was performed to explore the correlation between mRNA BAX/BCL-2 expression and oocyte quality in endometriosis compared to non-endometriosis subjects. Methods: This was a cross-sectional study. 15 endometriosis and 15 non-endometriosis subjects were recruited through convenience sampling at Cipto Mangunkusumo Hospital, Jakarta. All subjects underwent follicle stimulation with recombinant follicle-stimulating hormone (FSH). Granulosa cells were collected and tested for BAX and BCL-2 expression and the results were compared to the oocyte quality and fertilization rate of the patients. Results: The total dose of recombinant FSH received by the endometriosis group was significantly higher compared with that of the non-endometriosis group (p = 0.005). There was a difference in BAX level (p = 0.029) and BCL-2 level (p<0.001) between groups. However, the BAX/BCL-2 ratio did not differ significantly (p = 0.787) between groups. No significant correlation was found between the BAX/BCL-2 ratio and any of the oocyte quality parameters measured. Conclusion: We found that there is a significantly higher dose in total dose recombinant FSH received by the endometriosis group compared with the non-endometriosis group. We also found that there was no significant difference in BAX/BCL-2 ratio between the endometriosis and non-endometriosis groups.
El Discurso Capitalista Neoliberal desde una perspectiva lacaniana
Authors: Fair Hernán 
Published: January 2019

Este trabajo analiza el modo de construir subjetividad política del capitalismo neoliberal desde herramientas de la teoría de los discursos de Jacques Lacan. Se concluye que durante los años noventa el neoliberalismo se constituyó como un nuevo Discurso Amo. El nuevo Amo se estructuró mediante una articulación aggiornada del Discurso Capitalista con el Discurso Universitario y una reformulación del Discurso del Amo Antiguo. A partir de las construcciones metafóricas y los mandatos superyoicos de sus representantes y voceros, este discurso fue investido de un goce y un plus de goce lenguajero y corporal. A su vez, el Amo se mostró transfiriendo una parte del goce al Esclavo-Trabajador mediante una fantasía de libertad para elegir de forma plena y autónoma en el mercado, participar horizontalmente con el patrón en el nuevo orden flexible y acceder, vía el sacrificio, a un futuro de derrame de las riquezas de los ricos. Esta ilusión de retorno del goce al Esclavo fortaleció la dominación política del Amo-Empresario. En el caso argentino, junto con lapermanencia de la Convertibilidad como objeto a causa de deseo, de Menem a De la Rúa (1989-2001) se encontró un cambio de registro en los mandatos superyoicos y en las fuentes de goce, dentro de un mismo Discurso Capitalista Neoliberal de disciplinamiento social.

A pesar de que existe una larga tradición de migraciones al exterior en Colombia, durante los últimos diez años ha habido un aumento significativo como consecuencia de eventos y circunstancias que han transformado abruptamente las condiciones de vida de la población colombiana. Este artículo se enfoca en estudiar el desarrollo de las tendencias de la tercera ola migratoria de la población colombiana al exterior entre los años 2005 y 2015, revisando los crecimientos y decrecimientos de dicha población hacia los destinos tradicionales, así como en detectar la aparición de nuevos destinos, la naturaleza de las migraciones hacia estos y las estimaciones del número de colombianos en estos países durante este periodo.
Migraciones internacionales, fronteras y Estados. ¿Cómo interpretar el régimen de frontera desde América del Sur?
Authors: Alvites Baiadera Angélica Paola 
Published: January 2019

En el artículo nos preguntamos cómo interpretar el régimen de frontera desde América del Sur. Para esto, reflexionamos sobre la posible relación entre migraciones internacionales, Estados y fronteras en el campo de los estudios migratorios, con el fin de construir categorías analíticamente situadas. Desde una metodología cualitativa, analizamos un conjunto de documentos vinculados a esta temática: declaraciones finales e informes técnicos de la Conferencia Suramericana sobre Migraciones (csm), así como resoluciones del Mercado Común del Sur (Mercosur) y de la Comunidad Andina e Naciones (can). Para el análisis de estos documentos, e interpretar el régimen de frontera de la región, construimos tres puntos de apoyo: la externalización asociada al proceso de regionalización de las políticas de control migratorio en Sudamérica; el cruce de un territorio nacional a otro, vinculado a los controles en puntos de frontera; y, por último, las fronteras de permanencia, enlazadas a los mecanismos estatales que estipulan los modos de residir “en destino”. Sudamérica se constituye como unasubregión del régimen de frontera global, que favorece y estimula, no sin conflictos y tensiones, políticas de control ordenado, integrado y planificado de las migraciones. En “las fronteras”, los controles distinguen a los migrantes pertenecientes a un Estado miembro de la can, del Mercosur o uno extraregional. De este modo, los sujetos quedan supeditados al estrato político que ocupa el Estado del cual son parte al fijar un modo diferencial para ingresar y permanecer “en destino” según origen nacional.
Bilateral dentigerous cysts: an updated literature review and report of a case with associated root resorption
Authors: Yonel Zehra , McIntosh Arathi Papineni , Donaldson Neil , Murphy Michael , Taneja Pankaj 
Published: January 2019

Abstract: Dentigerous cysts, though common, rarely present bilaterally. The rarity of bilateral presentation is highlighted by a review of the literature which revealed a total of 77 published cases. This demonstrated that, although 29% were asymptomatic, 58% presented with swelling and 22% with pain. The majority of patients were treated with enucleation alone (73%); 17% were managed with marsupialisation, and 8% treated with a combination of surgical techniques. Of cases reported, 16% had resorption of adjacent teeth, with 8% describing resorption of permanent dentition. This highlights the importance of symptom recognition and appropriate radiographic investigation from the outset to allow prompt, appropriate treatment.CPD/Clinical Relevance: Dentigerous cysts are the second most common type of odontogenic cyst, however, their bilateral presentation in a syndrome-free patient is rare. Early recognition of symptoms, knowledge of appropriate investigations and management options are vital for ensuring optimal patient outcome.
Phantasmagoric City: Technologies of Immersion and Settler Histories in Montreal’s CitéMémoire
Authors: Chew May 
Published: January 2019

Abstract
This paper focuses on CitéMémoire, a multi-year outdoor exhibit located throughout historic Old Montreal. Organized around the confluence of Montreal’s 375th birthday, Canada’s Sesquicentennial, as well as Expo 67’s 50th anniversary, CitéMémoire uses large-scale interactive projections and augmented reality to tell the city’s history from the time of European contact onward. The exhibit’s technologies of immersion guide audiences through a spectacularized historical landscape, rendering notions of heritage and nation into palpable archives that audiences encounter directly through their bodies. This article demonstrates how archival and cultural technologies, which choreograph audiences’ bodily, imaginational, and affective positionalities, prove central to the ‘dreamwork’ of settler coloniality.
Multilingual learners learning about translanguaging through translanguaging
Authors: Choi Julie 
Published: January 2019

AbstractMobility, technology, personal and political circumstances provide enhanced opportunities for contact with new or different spaces, people, objects, and feelings. Such affordances in turn heighten possibilities for ways of thinking about or experiencing identity, agency, place, and perceptions of the world differently. In this paper, I draw on photographs, written artifacts, material objects, and interview data from two Japanese International students’ self-initiated project on undoing deeply ingrained cultural discourses and practices during their one-year study abroad program in Sydney. Using a narrative inquiry approach and drawing on ideas from translanguaging theory, I illustrate an accumulation of learning experiences that happened during the students’ out-of-classroom translanguaging practices that eventually led them to a transformational understanding of the importance of activating all of their meaning-making resources for meaningful self-development. Finally, I discuss the transformative value in enacting translanguaging practices in relation to language learning.
Satisfying Boundary Conditions in Homogeneous, Linear-Elastic and Isotropic Half-Spaces Subjected to Loads Perpendicular to the Surface: Distributed Loads on Adjacent Contact Areas
Authors: Ferretti Elena 
Published: January 2019

Abstract
This work originates from an experimental program on strain distribution near the loaded surface of an airfield concrete pavement,which provided us with results that contrast with the rheological predictions of Boussinesq for a homogeneous, linear-elastic and isotropic half-space. We already reviewed and extended the original work carried out by Boussinesq in previous papers, to provide a closed form second order solution that enabled us to establish a good match between analytical and experimental findings for point-loads. In this paper, we have explained why Boussinesq’s closed form solution for a homogeneous linear-elastic and isotropic half-space subjected to a point-load is not exact, as believed until now, but approximated. Then, we have shown that our second order solution is the actual solution of Boussinesq’s problem. We have also presented the numerical analysis of second order for rectangular and elliptical contact areas, both loaded by uniform and parabolic laws of external pressure. Moreover, we have evaluated the interaction effect provided on the surface of a concrete half-space by the twin wheels of an aircraft landing gear. Extension of the solution to layered systems is also possible, for improving the knowledge of stress propagation into airfield pavements and promoting more effective design standards.

Displaced Art and the Reconstruction of Memory: Ukrainian Artists from Crimea and Donbas
Authors: Lashchuk Iuliia 
Published: January 2019

Abstract
After the occupation of Crimea and the conflict in Eastern Ukraine, many people were forced to leave their homes and look for a new place to live. The cultural context, memories, narratives, including the scarcely built identity of artificially made sites like those from Donbas (Donetsk and Luhansk regions) and the multicultural identity of Crimea, were all destroyed and left behind. Among the people who left their roots and moved away were many artists, who naturally fell into two groups-the ones who wanted to remember and the ones who wanted to forget. The aim of this paper is to analyse the ways in which the local memory of those lost places is represented in the works of Ukrainian artists from the conflict territories, who were forced to change their dwelling- place. The main idea is to show how losing the memory of places, objects, sounds, etc. affects the continuity of personal history.

Challenges in Implementing an E-Learning Education Program for Syringe Pump Use
Authors: Saint-Marc Patricia , Ratiney Robert , Schlatter Joël 
Published: January 2019

Abstract
To prevent the incidence of risks imputable to human error during the process of preparing the infusion pump, clarity in teaching and learning are required. Because traditional classroom training is difficult and time-consuming, the aim of the present study was to challenge the implementation of an e-learning education program for syringe pump use. The impact of the e-learning program was evaluated with 100 nurses between March and June 2016. The e-learning program significantly increased general baseline knowledge in syringe pump use; however, aspects of the program confused participants. The feedback from 98 % of nurses on the e-learning program was that it was effective in helping them with this skill. However, only 54 % opted for the e-learning program versus traditional training. The present study showed nurses preferred a blended learning format. Based on our hospital incident and error reports, this study shows local training requires a specific approach strategy for syringe pump education.
New Traffic Conflict Measure Based on a Potential Outcome Model
Authors: Yamada Kentaro , Kuroki Manabu 
Published: January 2019

Abstract
A key issue in the analysis of traffic accidents is to quantify the effectiveness of a given evasive action taken by a driver to avoid crashing. Since 1977, the widely accepted definition for this effectiveness measure, which is called traffic conflict, has been “the risk of a collision if the driver movement remains unchanged.” Although the definition is expressed counterfactually, the full power of counterfactual analysis was not utilized. In this paper, we propose a counterfactual measure of traffic conflict called Counterfactual Based Conflict (CBC). The CBC is interpreted as the probability that a driver avoided a crash actually by taking an evasive action in the counterfactual situation in which the crash would have occurred if he/she had not taken an evasive action and the crash would not have occurred if he/she had taken an evasive action. The CBC captures realistic aspects of the traffic situation, and lends itself to modern causal analysis. In addition, we provide some of identification conditions for the CBC. Furthermore, we formulate bounds on the CBC when the proposed identification conditions are violated. Finally, through an application of the CBC to the 100-Car Naturalistic Driving Study, we discuss the usefulness and limitations of the proposed measure.
Regular double p-algebras

Published: January 2019

Abstract
In this paper, we investigate the variety RDP of regular double p-algebras and its subvarieties RDP

n
, n ≥ 1, of range n. First, we present an explicit description of the subdirectly irreducible algebras (which coincide with the simple algebras) in the variety RDP
1 and show that this variety is locally finite. We also show that the lattice of subvarieties of RDP
1, LV
(RDP
1), is isomorphic to the lattice of down sets of the poset {1} ⊕ (ℕ × ℕ). We describe all the subvarieties of RDP
1 and conclude that LV
(RDP
1) is countably infinite. An equational basis for each proper subvariety of RDP
1 is given. To study the subvarieties RDP

n
with n ≥ 2, Priestley duality as it applies to regular double p-algebras is used. We show that each of these subvarieties is not locally finite. In fact, we prove that its 1-generated free algebra is infinite and that the lattice of its subvarieties has cardinality 2
ℵ
0
. We also use Priestley duality to prove that RDP and each of its subvarieties RDP

n
are generated by their finite members.

Abstract
In this paper, we establish fixed point theorems for one and two selfmaps in b-metric-like spaces, using (s, q)-contractive and F-(ψ, φ, s, q)-contractive conditions, defined by means of altering distances and 𝓒-class functions. Our theorems unify, extend and generalize corresponding results in the literature.
Effect of Sesbania sesban on cultivation of Agaricus bisporus, Basidiomycota, and properties of spent mushroom compost outcome
Authors: Rashid Husam Mahmod , Abed Idham Ali , Owaid Mustafa Nadhim 
Published: January 2019

Abstract
Because wheat straw has a high cost as a feed for livestock, this work aims to use straw of Egyptian pea (Sesbania sesban) in compost preparation as an alternative for the cultivation of Agaricus bisporus. Six composts were used within this study on two mushroom strains A. bisporus (C9 and F599 strains). The type of compost has a significant (p<0.05) effect on the size of button mushroom fruits. WHS1 compost exhibited the best diameter of pileus at 5.28 cm while WCS1 compost showed the lowest diameter reaching 4.68 cm. A. bisporus C9 had the longest stipe while A. bisporus F599 has the greatest cap diameter.A. bisporus F599 showed a larger ratio of the diameter of pileus to the length of stipe (DP/ LS ratio) (1.14) compared with C9 (1.07). C:N ratios of compost decreased significantly (p<0.05) after cultivation of mushrooms because of the high increase of nitrogen content in spent mushroom compost (SMC). Finally, the straw of S. sesban is suitable as a supplement for the cultivation of A. bisporus.
