Abstract

Yasushi Matsuzawa,1 Kiyoshi Hibi,1 Kenichiro Saka,1 Masaaki Konishi,1 Eiichi Akiyama,1 Naoki Nakayama,1 Toshiaki Ebina,1 Masami Kosuge,1 Noriaki Iwahashi,1 Nobuhiko Maejima,1 Kouichi Tamura,2 Kazuo Kimura1 1Division of Cardiology, Yokohama City University Medical Center, Yokohama, Japan; 2Department of Medical Science and Cardiorenal Medicine, Graduate School of Medicine, Yokohama City University, Yokohama, Japan Background: Thinning of the fibrous cap of atherosclerotic plaque is a major component of plaque vulnerability. The high resolution of optical coherence tomography (OCT) provides an accurate measurement of fibrous-cap thickness. Endothelial dysfunction is associated with inflammation and enhanced local expression of matrix metalloproteinases. We investigated the association between endothelial dysfunction and OCT-derived thin-cap fibroatheroma (TCFA) in patients with acute coronary syndromes (ACS). Methods: Seventy-four patients with ACS, who underwent both OCT examinations of the culprit lesion before percutaneous coronary intervention and peripheral endothelial function assessment as assessed by logarithmic value of reactive hyperemia index (Ln_RHI), were enrolled. Age-, sex-, hypertension-, and diabetes-matched non-coronary artery disease (non-CAD) patients were also enrolled (n=15). Results: Ln_RHI levels were significantly lower in ACS patients compared with non-CAD patients (0.56±0.26 vs 0.74±0.22, P=0.01). Furthermore, the Ln_RHIs of ACS patients with TCFA (n=44) were significantly lower than those of ACS patients without TCFA (n=30) (0.50±0.24 vs 0.65±0.26, P=0.01). There was a weak but significant positive correlation between Ln_RHI and fibrous-cap thickness (Spearman’s ρ=0.25, P=0.03). Multivariate logistic regression analysis identified lower Ln_RHI as an independent factor associated with TCFA in ACS patients (OR per 0.1 increase in Ln_RHI: 0.78 [95% CI: 0.62–0.98], P=0.03). Conclusion: Advanced endothelial dysfunction significantly correlates with a thin fibrous cap of coronary plaques in patients with ACS. Keywords: peripheral endothelial function, optical coherence tomography, thin-cap fibroatheroma, plaque vulnerability

Abstract

Optical coherence tomography (OCT) has been widely adopted in research on coronary atherosclerosis and adopted clinically to optimize percutaneous coronary intervention. In this Review, Jang and colleagues summarize this rapidly progressing field, with the aim of standardizing the use of OCT in coronary atherosclerosis.Since optical coherence tomography (OCT) was first performed in humans two decades ago, this imaging modality has been widely adopted in research on coronary atherosclerosis and adopted clinically for the optimization of percutaneous coronary intervention. In the past 10 years, substantial advances have been made in the understanding of in vivo vascular biology using OCT. Identification by OCT of culprit plaque pathology could potentially lead to a major shift in the management of patients with acute coronary syndromes. Detection by OCT of healed coronary plaque has been important in our understanding of the mechanisms involved in plaque destabilization and healing with the rapid progression of atherosclerosis. Accurate detection by OCT of sequelae from percutaneous coronary interventions that might be missed by angiography could improve clinical outcomes. In addition, OCT has become an essential diagnostic modality for myocardial infarction with non-obstructive coronary arteries. Insight into neoatherosclerosis from OCT could improve our understanding of the mechanisms of very late stent thrombosis. The appropriate use of OCT depends on accurate interpretation and understanding of the clinical significance of OCT findings. In this Review, we summarize the state of the art in cardiac OCT and facilitate the uniform use of this modality in coronary atherosclerosis. Contributions have been made by clinicians and investigators worldwide with extensive experience in OCT, with the aim that this document will serve as a standard reference for future research and clinical application.

Abstract

The relevance of this article lies in the need to study Internet media in the information and communication environment, since new media technologies have entered the arena of election communication, the role of which is increasing both in the campaign process and in the election campaign as a whole. The purpose of the study is to determine the features of new media use in election campaigns in Russia. Research methods: as a research method, we used the method of individual in-depth interview, which allows us to identify and characterize the main methods of using new media technologies in election communication. Research results: the article shows the main ways and methods of using new media in election campaigns. The reasons and prerequisites for the use of new media technologies for the implementation of the electoral process are highlighted. The factors that determine the low level of new media use in the election campaign are determined. The effectiveness of new media functions in the electoral process is shown. The main prospects of development in the use of new media in election campaigns are considered. The novelty and originality of the study lies in the fact that the features of Internet media use in the electoral process are studied. For the first time, we the properties that allow new media technologies to use them in a completely different aspect than traditional media are identified: interactivity, multimedia content, efficiency in publishing, low cost and high speed of distribution of information content, as well as its availability and the ability to provide targeted information. It is determined that due to the above-mentioned properties of new media in political communication the following goals are achieved: presentation of political projects, the impact of the highlighted agenda on certain segments of the population, disseminating information about the activities of a candidate or party, collecting funds for the campaign, as well as the interaction with means of mass communication. For the first time, the functions of Internet media in the electoral process are highlighted, which are relevant: information-based, public opinion formation, mobilization, advertising, collection of monetary donations, and control over the conduct of election campaigns. It is shown that for Pro-government campaigns, the main functions of Internet media in the electoral process are information-based, formation of public opinion and image of the candidate, legitimization of the election process in the mass media, and the function of an additional source of information. For non-system opposition, the main functions of Internet media in the electoral process are information-based, communication, mobilization (which are especially manifested in the organization of volunteers’ work), the formation of the candidate’s image, and the collection of monetary donations. It is determined that the use of new media technologies by Pro-government campaigns differs significantly from opposition campaigns. It is shown that Pro-government candidates actively use traditional methods of interaction with voters: outdoor advertising, print media, local and Federal TV channels, not letting opposition candidates into it. It is determined that the technologies used by the headquarters of candidates from the government are less diverse and do not change over time. Interaction tools depend on the candidate and local electoral specifics. It is revealed that communication on media platforms between opposition supporters is more emotional, sincere, and fanatical. These people are distinguished by having a strong internal position and committed attitude to the policy of a representative of the non-system opposition. It is determined that the media services of the headquarters of Pro-government candidates mainly provide information presence of the candidate, explanatory rhetoric and legitimization of the election process on the media platforms. For the first time, it is revealed that even on new media platforms, Pro-government campaigns for the most part continue to use the vertical model of communication, placing the main emphasis on administrative resources. It is shown that the role of new media will grow more and more. Practical significance: the data Obtained in this work can be used in social psychology, pedagogy, age psychology, sociology, as well as for further theoretical development of this issue.

Abstract

La sobrecarga de trabajo de los docentes puede ocasionar desafíos para los docentes que provoquen agotamiento a largo plazo si no se abordan. En consecuencia, el presente estudio tiene como objetivo examinar las fuentes de prevención del agotamiento desde las perspectivas de los supervisores EFL (inglés como lengua extranjera). Los participantes fueron 85 supervisores de EFL iraníes cuyo trabajo consistía en observar y dar retroalimentación a los maestros sobre su desempeño docente en varios niveles de dominio del idioma, desde los niveles de primaria hasta los avanzados. En este estudio se empleó un diseño secuencial de método mixto. Primero, la recopilación de datos cualitativos se realizó mediante entrevistas con 30 participantes para determinar las fuentes de prevención del agotamiento desde la perspectiva de los supervisores. A continuación, se diseñó un cuestionario de prevención de agotamiento utilizando los resultados de las entrevistas, después de lo cual se administró a los participantes restantes. Los datos recopilados fueron analizados por factores para identificar los componentes de la construcción de prevención de agotamiento. Los resultados del análisis de contenido de los datos de la entrevista indicaron que el apoyo de los maestros por parte de sus colegas, la situación menos estresante y la satisfacción laboral fueron las principales fuentes de prevención del agotamiento. El análisis factorial mostró las mismas fuentes de agotamiento que los componentes principales de la construcción de prevención de agotamiento. Los hallazgos de este estudio enfatizan la contribución del apoyo educativo y emocional de los maestros, proporcionando un lugar de trabajo constructivo y saludable, así como ingresos deseables como formas de prevención del agotamiento en los maestros de EFL., Teacher work overload can cause challenges for teachers leading to burnout in the long term if not addressed. Consequently, the present study aims at examining the sources of burnout prevention from EFL (English as a foreign Language) supervisors’ perspectives. The participants were 85 Iranian EFL supervisors whose job was observing and giving feedback to teachers about their teaching performance at various levels of language proficiencies from elementary to advanced levels. A sequential mixed method design was employed in this study. First, collection of qualitative data was performed using interviews with 30 participants in order to determine the sources of burnout prevention from supervisors’ perspectives. Next, a burnout prevention questionnaire was designed using the results of the interviews, afterwhich it was administered to the remaining participants. The collected data were factor analyzed to identify the components of burnout prevention construct. Results of content analysis of the interview data indicated that teachers’ support from their colleagues, less stressful situation, and job satisfaction were the main sources of burnout prevention. Factor analysis showed the same sources of burnout as the main components of the burnout prevention construct. The findings of this study emphasize on the contribution of teachers’ educational and emotional support, providing constructive and healthy working place, as well as desirable income as ways for prevention of burnout in EFL teachers., A sobrecarga de trabalho do professor pode causar desafios para os professores, levando a esgotamento a longo prazo, se não forem abordados. Consequentemente, o presente estudo tem como objetivo examinar as fontes de prevenção de burnout das perspectivas dos supervisores de EFL (inglês como língua estrangeira). Os participantes foram 85 supervisores iranianos de EFL, cujo trabalho era observar e dar feedback aos professores sobre seu desempenho no ensino em vários níveis de proficiência linguística, do nível básico ao avançado. Um método misto sequencial foi empregado neste estudo. Primeiro, a coleta de dados qualitativos foi realizada por meio de entrevistas com 30 participantes, a fim de determinar as fontes de prevenção de burnout na perspectiva dos supervisores. Em seguida, foi elaborado um questionário de prevenção de burnout, utilizando os resultados das entrevistas, após o qual foi aplicado aos demais participantes. Os dados coletados foram analisados por fatores para identificar os componentes do construto de prevenção de burnout. Os resultados da análise de conteúdo dos dados da entrevista indicaram que o apoio dosprofessores de seus colegas, a situação menos estressante e a satisfação no trabalho foram as principais fontes de prevenção de burnout.
