Published: October 2019

Zusammenfassung
Hintergrund Ziel der vorliegenden Konsensusfindung war es, eine Verbesserung der Versorgungsqualität zur Optimierung und Vereinheitlichung der Lymphadenektomie bei der Lungenmetastasenchirurgie mit allgemein akzeptierten Definitionen und Standards zu erreichen.
Material und Methoden Der Expertenkonsens wurde mittels eines 2-stufigen Delphi-Prozesses mit anschließender Expertenkonferenz etabliert. Ein Konsens wurde festgestellt, wenn 75% der Experten zustimmten.
Ergebnisse Von den kontaktierten 76 Experten (Fachärzte für Thoraxchirurgie mit Leitungserfahrung) beteiligten sich an der 1. Fragerunde 49 und an der 2. Fragerunde 47 Experten. An der Konferenz nahmen 43 Experten teil. Der bevorzugte Zugangsweg bei solitärer subpleuraler Lungenmetastasierung ist die Videothorakoskopie (VATS), bei multiplen Lungenmetastasen hingegen die anterolaterale Thorakotomie. Eine Lymphadenektomie wird unabhängig vom Zugangsweg durchgeführt. Die systematische Lymphadenektomie bzw. systematisches Lymphknotensampling ist fester Bestandteil der Lungenmetastasektomie bei kolorektalen Karzinomen, Nierenzellkarzinomen und nicht seminomatösen Keimzelltumoren. Die Größe der Lungenmetastase hat keinen Einfluss auf die Lymphadenektomie per se. Der Eingriff wird bei intraoperativem Nachweis einer Lymphknotenmetastasierung komplettiert und nicht abgebrochen.
Schlussfolgerung Mit den im Expertenkonsens erarbeiteten Kriterien liegen erstmals Empfehlungen für die thorakale Lymphadenektomie bei der pulmonalen Metastasenchirurgie vor.

Abstract
Background B-lines on lung ultrasound are seen in decompensated heart failure, but their diagnostic value in consecutive patients in the acute setting is not clear. Chest CT is the superior method to evaluate interstitial lung disease, but no studies have compared lung ultrasound directly to congestion on chest CT.
Purpose To examine whether congestion on lung ultrasound equals congestion on a low-dose chest CT as the gold standard.
Materials and Methods In a single-center, prospective observational study we included consecutive patients ≥ 50 years of age in the emergency department. Patients were concurrently examined by lung ultrasound and chest CT. Congestion on lung ultrasound was examined in three ways: I) the total number of B-lines, II) ≥ 3 B-lines bilaterally, III) ≥ 3 B-lines bilaterally and/or bilateral pleural effusion. Congestion on CT was assessed by two specialists blinded to all other data.
Results We included 117 patients, 27 % of whom had a history of heart failure and 52 % chronic obstructive pulmonary disease. Lung ultrasound and CT were performed within a median time of 79.0 minutes. Congestion on CT was detected in 32 patients (27 %). Method I had an optimal cut-point of 7 B-lines with a sensitivity of 72 % and a specificity of 81 % for congestion. Method II had 44 % sensitivity, and 94 % specificity. Method III had a sensitivity of 88 % and a specificity of 85 %.
Conclusion Pulmonary congestion in consecutive dyspneic patients ≥ 50 years of age is better diagnosed if lung ultrasound evaluates both B-lines and pleural effusion instead of B-lines alone.

Abstract
Aim This paper presents the results of the 8th survey of myocardial perfusion SPECT (MPS) from the reporting year 2018.
Methods 291 questionnaires (184 practices (PR), 77 hospitals (HO), 30 university hospitals (UH)) were evaluated. Results of the last survey from 2015 are set in squared brackets.
Results MPS of 145 930 [121 939] patients were reported (+ 19.6 %). 76 % [78 %] of all patients were studied in PR, 16 % [14 %] in HO, and 8 % [8 %] in UH, mostly with a 2-day-protocol 48 % [50 %]. 99.96 % [98 %] of all MPS were performed with Tc-99 m radiopharmaceuticals and in 0.04 % with Tl-201.A pharmacological stress test was applied in 49 % [43 %] (23 % [22 %] adenosine, 26 % [20 %] regadenoson, dipyridamole or dobutamine together < 1 % [1 %]). Attenuation correction was performed in 26 % [25 %] of all MPS, gated SPECT in 86 % [80 %] of stress MPS, in 87 % [78 %] of rest and in 83 % [76 %] of all stress and rest MPS. 67 % [53 %] of the departments performed MPS scoring by default, whereas 16 % [24 %] did not apply this feature at all.69 % [60 %] reported an increase or no changes in their MPS patient numbers. One hundred twenty-six departments which participated in the surveys from 2009 to 2018 reported an increase in MPS by 44 %. 69 % [70 %] of the MPS were requested by ambulatory care cardiologists.
Conclusion The 2018 MPS survey reveals a high-grade adherence of routine MPS practice to current guidelines. The positive development in MPS performance and MPS numbers observed since 2012 remains ongoing.
Causes and Secondary Prevention of Acute Ischemic Stroke in Adults
Authors: Jensen Märit , Thomalla Götz 
Published: October 2019

AbstractStroke still remains a major cause of death and disability worldwide. Ischemic stroke is the most common type of stroke. Causes of ischemic stroke can be classified into large-artery atherosclerosis, cardiogenic embolism, small-vessel disease, stroke of other determined etiology, and stroke of undetermined etiology. Stroke causes in adults are mainly attributable to classical cardiovascular risk factors such as hypertension, diabetes, hypercholesterolemia, and smoking. In neuroimaging, stroke subtypes can be defined according to lesion localization and distribution (territorial infarct, lacunar infarct, hemodynamic infarct), which provide information as to the underlying etiology. Acute stroke management comprises rapid neurological assessment and rapid imaging to initiate effective reperfusion treatment with intravenous thrombolysis and mechanical thrombectomy. Stroke survivors are at increased risk of recurrent stroke. Therefore, diagnosis of the underlying cause and optimal secondary prevention is of importance. Pharmacologic secondary prevention includes antithrombotic therapy with antiplatelet drugs, oral anticoagulation, and treatment of vascular risk factors. Nonpharmacologic measures of secondary prevention comprise surgical or interventional revascularization of symptomatic carotid stenosis and interventional closure of patent foramen ovale.

Abstract

Objective The aim of this study is to compare the isokinetic knee muscles peak torque measurements and proprioception between the affected and intact limbs of patients with stroke, in addition to finding the correlation between knee muscles strength and lower limb function.

Methods Twelve patients with stroke (mean age 64.33 ± 6.140 years), with 3 to 7 months poststroke who can walk 25 feet independently without using or using assistive devices and full passive range of motion were included in the study. Biodex isokinetic dynamometer was used for measuring isokinetic strength at 90°/s, 120°/s, and 150°/s and isometric strength at 60°/s in both flexors and extensors of the knee, whereas proprioception was measured at 45°/s knee flexion, all for affected and intact limbs. Functional measurements were assessed using the Fugl-Meyer Assessment for Lower Limb scale and Barthel Index (BI).

Results The differences shown were found to be statistically significant between affected and intact limbs in isokinetic 90°/s flexion (p = 0.005), extension (p = 0.0013), and isometric at 60°/s flexion (p < 0.0001) knee muscle strengths and also the proprioception (p = 0.05). Significant positive correlation was found between isokinetic affected side knee flexion at 90°/s (r = 0.903) with BI (r = 0.704).

Conclusion There is a significant difference in peak torque measurements between affected and normal lower limbs of poststroke patients, as well as a significant correlation between the knee strength and lower limb functions. Furthermore, it can also be concluded that the differences in knee proprioception between the affected and intact limbs were shown to be significant.
“I am an adult now”
Authors: Prior Matthew T. 
Published: October 2019

AbstractThis narrative-based study employs membership categorization analysis to address the following question: How does a victim of abuse formulate and manage various categories and related descriptive details to story past trauma in ways that bring about new endings or insights in the present? Drawing on data taken from a larger research project on immigrant identity, the analysis centers on a Cambodian-Vietnamese man’s narrative of childhood abuse and adulthood confrontation. It shows how the teller, by recalibratingperson(e.g., ‘father-son’, ‘victim-abuser’),age(e.g., ‘young-old’),place(e.g., ‘North America-Vietnam’), and other categorial resources, re-stories people and events and their psycho-social and moral inferences and outcomes. By tracing how this narrative teller reconstitutes himself from ‘victim’ to ‘hero’, this study offers insight into how a local interactional event (e.g., a research interview) may be transformed into a therapeutic exchange. Insights for therapeutic (re)storying, narrative research, and second language (L2) research are discussed.
Membership categorization and storytelling
Authors: Day Dennis , Kjærbeck Susanne 
Published: October 2019

Abstract
In this paper, we demonstrate how the collaborative and sequential unfolding of a story ties into
the constitution of a membership categorization device which we have glossed as ‘us and them’. The data come
from a focus group activity where first and second generation immigrants to Denmark have been asked to discuss
their situation in Denmark. Using Ethnomethodological Conversation and Membership Categorization Analysis, we
present one story which involves a story-teller and his family and an elderly Danish couple living in the same
block of flats. In the telling of the story, co-participants align and affiliate, and disalign and
disaffiliate, at sequentially relevant junctions. We will argue that not only do such phenomena indicate
listenership and possible agreement to the moral of the story in its telling, but also to the morally
implicative categorical work involved in the story’s telling.
Place and membership categorization in a Hawaiian language radio show
Authors: Furukawa Toshiaki 
Published: October 2019

AbstractRecent articles by prominent scholars of discourse and interaction have renewed the debate over the relationship between membership categorization analysis (MCA) and conversation analysis (CA). Many consider CA and MCA as mutually informing, and that is the position I take in this paper. MCA has been conducted mainly with monolingual data, but in this study I examine Hawaiian language media talk by multilingual speakers. Place formulation is often intertwined with membership categorization, and I investigate how place is used to categorize people. Taking an MCA approach, I analyze the stories co-constructed by a radio show’s host, guest, and callers, all of whom speak predominantly in Hawaiian but occasionally switch into English. The goals of the paper are twofold: (1) to illustrate the procedural consequentiality of initiating, maintaining, and terminating an “ultra-rich topic” (Sacks 1992: 75), that is, place; and (2) to show how place is used to do categorial work.

Published: October 2019

Abstract
This paper developed a practical learning activity named “STEM - Play, Learn and Work” to increases students’ interest and engagement in the learning of STEM (Science, Technology, Engineering, and Mathematics). Because we need to show that STEM knowledge and skills can solve everyday problems and promote community and local products, one popular product in our local community is selected as a representative to be the main theme of learning. We designed the project-based learning activity combined various STEM subjects through steps of production for the representative from the beginning to the end. We used an experimental “STEM - Play, Learn and Work” to 19 students in grade ninth – twelfth in class of academic club. The learning outcomes including student performance and attitude towards STEM are discussed. The assessment results (one assessment taken before the activity, one after) show that the activity improved students’ knowledge in STEM subjects significantly. It also increased students’ positive attitude towards STEM and interest in STEM careers. Students have the opportunity to apply their meaningful STEM knowledge and skills to solve problems in everyday life through this practical activity.

Abstract
The purpose of this study is to investigate the secondary students’ decision making process when global socio-scientific issue (SSI) is applied to STEM-based learning. SSI overlap STEM framework adapted from the literature was designed to help students to take a responsible informed decision when considering global environmental issue as a part of their classroom activity. Thirty one students participated in the pre- and post-socio-scientific decision-making test. Data was also collected through class observation. Both quantitative and qualitative data were gathered and analysed; content analysis of qualitative data collected from student’s reasoning helped to explain the initial quantitative findings. Based on the qualitative analysis, the results revealed that the students’ abilities benefited from the SSI overlap STEM framework implementation. The results showed that there were considerable changes in the students’ decision making before and after the activity. It also indicated that the SSI overlap STEM framework designed for this study was effective and could be used in science classes.

Abstract
The study investigated the use of Facebook as an educational tool as well as the influence of Facebook integration into blended learning environment on English pronunciation teaching and learning activities. The subjects for the study consisted of 30 students who were the first-year English majors at Thai Nguyen University of Education. They were divided into two groups: the experimental group and the traditional group. Besides, there was a student teacher from the same university to be the subject of the experimental group. A combination of qualitative, quantitative and experimental approaches was employed to collect data and students’ views on this model. This allowed the researcher to get hold of a transformation in students’ pronunciation competence and their attitudes towards a blended format with supporting a social networking site (Facebook). The findings of the study indicate that Facebook retains outstanding features to offer a professional online course for English pronunciation learning, such as live lectures, group discussions, schedule events and etc. Furthermore, Facebook benefits the teachers in managing students’ learning autonomy so that the teacher is likely to grasp the ability of individuals in a short time. However, the use of Facebook still remains obstacles in the path of carrying out English pronunciation activities, and when putting it into blended-learning, the model handles these obstacles and limitations in the current learning and teaching of English pronunciation as well.
