Published: March 2018

Purpose: To describe abnormal dark (hyposignal) and white (hypersignal) lesions observed on optical coherence tomography angiography in central serous chorioretinopathy. Methods: Prospective, multicenter, and descriptive study including patients with active or quiescent central serous chorioretinopathy. All patients had undergone a complete ophthalmic examination. Results: Abnormal dark lesions were detected as “dark spots” and “dark areas” on optical coherence tomography angiography. A “dark spot” could correspond to six different abnormalities: pigment epithelium detachment, subretinal deposit, “Lucency” within surrounding subretinal fibrin, choroidal cavitation, choroidal excavation, and choroidal fluid. A “dark area” could be related to a serous retinal detachment or choriocapillary compression. Abnormal white lesions were also detected: A “white spot” could correspond with the leaking point on fluorescein angiography or with hyper-reflective dots; A “white filamentous pattern” at the Brüch’s membrane level corresponded to abnormal choroidal neovascular vessels. Conclusion: A semiology is described using optical coherence tomography angiography in central serous chorioretinopathy as abnormal dark and white lesions. Multimodal imaging is mandatory in addition to optical coherence tomography angiography to diagnose non-neovascular retinal and choroidal central serous chorioretinopathy lesions. However, optical coherence tomography angiography alone is helpful in detecting choroidal neovascular membrane in central serous chorioretinopathy.

Published: March 2018

Aortic graft infections are a rare but devastating complication of aortic revascularization. Often infections occur due to contamination at the time of surgery. Iatrogenic misplacement of the limbs of an aortobifemoral graft is exceedingly rare, and principles of evaluation and treatment are not well defined. We report 2 cases of aortobifemoral bypass graft malposition through the colon. Case Report: Case 1 is a 54-year-old male who underwent aortobifemoral bypass grafting for acute limb ischemia. He had previously undergone a partial sigmoid colectomy for diverticulitis. Approximately 6 months after vascular surgery, he presented with an occult graft infection. Preoperative imaging and intraoperative findings were consistent with graft placement through the sigmoid colon. Case 2 is a 60-year-old male who underwent aortobifemoral bypass grafting due to a nonhealing wound after toe amputation. His postoperative course was complicated by pneumonia, bacteremia thought to be secondary to the pneumonia, general malaise, and persistent fevers. Approximately 10 weeks after the vascular surgery, he presented with imaging and intraoperative findings of graft malposition through the cecum. Conclusions: Aortic graft infection is usually caused by surgical contamination and presents as an indolent infection. Case 1 presented as such; Case 2 presented more acutely. Both grafts were iatrogenically misplaced through the colon at the index operation. The patients underwent extra-anatomic bypass and graft explantation and subsequently recovered.
Total Elbow Arthroplasty Survey 2015: Current Service Provision and Future Improvements (England and Wales)
Authors: Abdelmalek Amir , Donaldson Oliver 
Published: March 2018

Background The number of total elbow replacement (TER) procedures conducted is relatively low compared to other joint arthroplasties. We have established a survey about current service provision and possible future improvements in the UK. Methods A British Elbow and Shoulder Society (BESS) approved online survey was circulated to its surgical members Results In total, 153 members of BESS responded. Almost 31% of respondents performed two to five TER in 2014; 28% performed none and 22.7% performed five to ten. Two-thirds of respondents did not perform any revision surgery. The main indication for TER was rheumatoid arthritis (33%), followed by acute trauma (28.5%). In addition, 67% of surgeons have an available ‘network’ for advice, either locally or regionally. Most primary procedures (93%) were carried out within the local units. However, 34% of complex primary or revision procedures were referred to another centre. Furthermore, 52% of respondents agree that, to be proficient in TER, a minimum number of procedures per annum should be performed: 62% stated that five procedures per annum should be considered as the minimum required. Suggestions for improvement included a hub and spoke model (48%) and a dedicated TER surgeon within the unit (45%). Conclusions The survey highlights the interest in exploring options for improving TER provision in the UK.
Parent-perceived isolation and barriers to psychosocial support: a qualitative study to investigate how peer support might help parents of burn-injured children
Authors: Heath Jennifer , Williamson Heidi , Williams Lisa , Harcourt Diana 
Published: March 2018

Introduction: Burn injuries can be traumatic and distressing for the affected child and family, with a prolonged period of recovery. This research explores parents’ experiences of support following their child’s injury and their thoughts on peer support specifically. Methods: Thirteen semi-structured interviews were conducted with parents/caregivers, a mean of three years after their child’s injury, either face-to-face or remotely. Responses were analysed using thematic analysis. Results: Analysis produced four themes and 11 sub-themes. These described parents’ experiences of loss, change, isolation and access to psychosocial support. This paper focuses on themes of isolation and parents’ access to psychosocial support. Discussion: Findings indicate that parents access psychosocial support following their child’s injury and often find it helpful; however, there is a prevailing sense of isolation. Parents often seek information online and find that this is lacking. Many parents reported that peer support would be valuable to them, particularly the sharing of experiential knowledge. Conclusion: An online resource may be beneficial for parents, but further research is needed to confirm the exploratory data gained to date, ensuring that any resource developed would meet the identified needs of parents.

Epidermal growth factor receptor and integrins control force-dependent vinculin recruitment to E-cadherin junctions
Authors: Sehgal Poonam , Kong Xinyu , Wu Jun , Sunyer Raimon , Trepat Xavier , Leckband Deborah 
Published: March 2018

ABSTRACT
This study reports novel findings that link E-cadherin (also known as CDH1)-mediated force-transduction signaling to vinculin targeting to intercellular junctions via epidermal growth factor receptor (EGFR) and integrins. These results build on previous findings that demonstrated that mechanically perturbed E-cadherin receptors activate phosphoinositide 3-kinase and downstream integrins in an EGFR-dependent manner. Results of this study show that this EGFR-mediated kinase cascade controls the force-dependent recruitment of vinculin to stressed E-cadherin complexes – a key early signature of cadherin-based mechanotransduction. Vinculin targeting requires its phosphorylation at tyrosine 822 by Abl family kinases (hereafter Abl), but the origin of force-dependent Abl activation had not been identified. We now present evidence that integrin activation, which is downstream of EGFR signaling, controls Abl activation, thus linking E-cadherin to Abl through a mechanosensitive signaling network. These findings place EGFR and integrins at the center of a positive-feedback loop, through which force-activated E-cadherin signals regulate vinculin recruitment to cadherin complexes in response to increased intercellular tension.

Cuba y el Socialismo del siglo XXI
Authors: Víctores Iván Porfirio Santos , García Miguel Ángel Hernández 
Published: March 2018

El presente artículo trata acerca de cómo, después de la desaparición del socialismo en la URSS y en Europa del Este, el llamado Socialismo del siglo XXI representa el desafío actual de reinventar o renovar el socialismo; tomando en cuenta las experiencias de los socialismos que se vivieron, aunque partiendo siempre de las condiciones y la realidad concreta y particular de cada país. Cuando se habla de Socialismo del Siglo XXI no se trata sobre algo definitivamente acabado, conceptualizado, sino precisamente sobre un constructo en desarrollo, el cual es la expresión actual de un abordaje renovado de la construcción del socialismo. Cuba, que inició su proceso revolucionario a mediados del siglo pasado, constituye, con su proyecto de actualización del socialismo, un ejemplo paradigmático donde, con sus características y particularidades históricas, encontramos lo que podríamos llamar una transición del socialismo clásico alternativo sui generis del siglo XX al socialismo del siglo XXI, con la adopción de políticas públicas que estimulen la sostenibilidad del desarrollo económico y social del país mediante la consolidación de un socialismo próspero y sostenible, comprometido con los valores fundacionales históricos del proyecto social cubano.

The Data was collected through interview, observation, and documentation. This research get the fact that the presence of Islamic paramilitary troops from Solo Residency in the area of conflict turned out to be one of the factors that contributed worsen the problem. They can not be harmony adhesive agent, but on the contrary, that the presence of Islamic paramilitary troops in conflict areas will add a warm existing problems because they have "advocacy agenda" against each of the parties in conflict so that does not result in a harmonious relationship in terms of religious harmony.[Penelitian kualitatif ini bertujuan untuk mengungkapkan terjadinya konflik antarmasyarakat Dukuh Bedowo, Desa Jetak, Kecamatan Sidoharjo, Kabupaten Sragen dengan jamaah Santri Luwung disertai dengan keterlibatan laskar-laskar Islam di dalam kronologi konflik Santri Luwung. Pengumpulan data dilakukan dengan teknik wawancara, observasi, dan dokumentasi. Penelitian ini mendapatkan fakta bahwa kehadiran laskar-laskar yang berasal dari Solo Raya di wilayah konflik ternyata menjadi salah satu faktor yang ikut memperkeruh permasalahan. Mereka tidak dapat menjadi agen perekat kerukunan, namun justru sebaliknya, bahwa dengan kehadiran laskar-laskar di wilayah konflik akan menambah hangat permasalahan yang ada karena mereka mempunyai “agenda advokasi” terhadap masing-masing pihak yang sedang bertikai sehinga mengakibatkan terjadinya relasi yang tidak harmonis dalam hal kerukunan umat beragama.]

Minne, glemsel og identitet i Jonas Hassen Khemiris romaner
Authors: Myhr Annika Bøstein 
Published: March 2018

Abstract
Based on a comparative analysis of Jonas Hassen Khemiri’s three novels Ett öga rött (2003), Montecore, en unik tiger (2006), and Allt jag inte minns (2015), this article explores the significance of memories and forgetting to the development of both individual and collective identity. More specifically, the article discusses which narrative devices Khemiri employs in showing how the identities of the novels’ protagonists are influenced by memories and forgetting, and deliberates what the implications of Khemiri’s novels may be, for our understanding of individual as well as collective identity in today’s culturally diverse Scandinavian societies.

Published: March 2018

Abstract
Time series data are of great importance for monitoring vegetation phenology in the dry sub-humid regions where change in land cover has influence on biomass productivity. However few studies have inquired into examining the impact of rainfall and land cover change on vegetation phenology. This study explores Seasonal Trend Analysis (STA) approach in order to investigate overall greenness, peak of annual greenness and timing of annual greenness in the seasonal NDVI cycle. Phenological pattern for the start of season (SOS) and end of season (EOS) was also examined across different land cover types in four selected locations. A significant increase in overall greenness (amplitude 0) and a significant decrease in other greenness trend maps (amplitude 1 and phase 1) was observed over the study period. Moreover significant positive trends in overall annual rainfall (amplitude 0) was found which follows similar pattern with vegetation trend. Variation in the timing of peak of greenness (phase 1) was seen in the four selected locations, this indicate a change in phenological trend. Additionally, strong relationship was revealed by the result of the pixel-wise regression between NDVI and rainfall. Change in vegetation phenology in the study area is attributed to climatic variability than anthropogenic activities.
Transformative research: personal and societal
Authors: Mertens Donna M. 
Published: March 2018

AbstractTransformative researchers have the potential to contribute to both personal and societal transformation. In this article, I argue that the two are intertwined and that personal transformation is a necessary component of research that is designed to support change at the societal level in the form of furthering human rights and social justice. I describe a transformative framework that examines assumptions related to ethics, the nature of reality, epistemology, and methodology that can guide researchers who choose to address both the personal and societal levels of transformation. Ethically, researchers need to examine who they are and who they are in relation to the community in which they are working. This process goes beyond self-examination to a critical analysis of the cultural blinders that might obscure our ability to contribute to positive impacts. I put forth the hypothesis that if we design our research so that it explicitly addresses issues of discrimination and oppression that the probability of personal and social transformation increases.

Published: March 2018

Zusammenfassung
In diesem Beitrag wird ein im Studienjahr 2015/16 durchgeführtes kooperatives Filmseminar vorgestellt, in dem Studierende im Master-Studiengang Deutsch als Fremdsprache (M.A. DaF) und Studierende im Bachelor-Studiengang Design (B.A. Design) an der German-Jordanian University in Amman (Jordanien) gemeinsame Filme zum Thema Heimat drehten. Die hinter diesem Projekt stehende Idee war, Studierende des M. A. DaF, die sich mit kulturellen Deutungsmustern bzw. Konstruktionen in dem Seminar Kulturstudien beschäftigen und B. A.-Design-Studierende, die lernen mit einer hochwertigen Filmausrüstung professionell umzugehen, für ein Semester zusammenzuführen, um ein gemeinsames Ziel zu erreichen: Vier Kurzfilme in den Genres Komödie, Portrait, Drama und Reportage zum Thema. Während die technische Produktion der Filme für die B. A.-Design-Studierenden im Sinne der Medienverwendung im Vordergrund stand, war der Fokus bei den M. A.-DaF-Studierenden im Sinne der Mediendidaktik auf den inhaltlichen Prozess gerichtet, d. h. von der Ideenentwicklung bis zur filmischen Umsetzung. Beiden Studiengängen gemeinsam war das handlungsorientierte Lernen und die Förderung der Kernkompetenzen Teamarbeit, Organisationsgeschick, Leitungsfähigkeit und Zeitmanagement. In dem Beitrag wird nach einer theoretischen Diskussion zu dem Einsatz von Filmen als Medium im DaF-Unterricht und dieses insbesondere vor dem Hintergrund der machtvollen Bildorientiertheit der neuen Medien, dessen Eignung zur Vermittlung kultureller Inhalte, die Vorgehensweise, der Verlauf und die Bewertungsgrundlagen des Projektes vorgestellt. Nicht zuletzt werden die Vorteile und Herausforderungen eines solchen interdisziplinären Projektes thematisiert.

Abstract

Background: Anterior cruciate ligament (ACL) reconstruction is a commonly performed procedure and considered to be the gold standard in restoring knee function and stability in ACL-deficient knees. The TransLateral all-inside technique implies the use of only two portals – anterolateral and anteromedial, without the use of an accessory portal. The work is done using the lateral portal, while the medial portal serves as a viewing site. Only a few studies have been published regarding the assessment of the functional and clinical outcomes of this novel technique.

Aim of the study: To determine the clinical effectiveness of the TransLateral procedure used for ACL reconstruction and its ability to re-establish joint functionality and stability in ACL-deficient knees.

Material and methods: A prospective study was conducted at the Orthopedics and Traumatology Clinic no. 2 in Tîrgu Mureș. Thirty-two patients matched our inclusion criteria and were operated using the TransLateral technique for ACL reconstruction. Outcome assessment was performed using the Knee injury and Osteoarthritis Outcome Score (KOOS), the Lysholm score and the Tegner Activity Scale. The questionnaires include items referring to pain, physical functioning, sports activities, and quality of life. Operative time and ACL graft size were also documented.

Results: All patients underwent single-bundle ACL restoration using a quadrupled semitendinosus tendon. Out of 32 patients, 21 had associated meniscus lesions and 8 collateral ligament injuries. Mean graft diameter was 8.7 mm and mean length 63.2 mm. Significantly improved KOOS values were found at 12 months post-surgery regarding the mean baseline score: 59.3 ± 5.3 vs. 95.3 ± 4.9, p <0.0001. The Lysholm score improved from a mean of 56.3 ± 4.9 to 93.9 ± 5.6, p <0.0001 at the end-point. The Tegner activity scale ranged from 3.8 ± 1.9 to 5.9 ± 2.4, p <0.0001 at the final follow-up.

Conclusions: The TransLateral technique proved its clinical effectiveness and its ability to restore knee stability after ACL reconstruction surgery.
