Aim. To examine the impact of late gadolinium enhancement (LGE) in the left ventricular myocardium on magnetic resonance imaging (MRI) on overall mortality and the phases of arrhythmic events in patients with ischemic cardiomyopathy and implantable cardioverter defibrillator (ICD).Methods. This was a single-center retrospective study. A total of 382 medical records of patients from the period between 2019 and 2022, who underwent ICD implantation as part of primary prevention of sudden cardiac death at National Centre of Cardiovascular Surgery, were analyzed. Seventy-four patients were selected for the study. Observation was conducted through in-person examinations and remote monitoring. Endpoints evaluated included overall mortality and arrhythmic events. The cause of death was determined based on the “Promed” medical database. Patients who reached a specific endpoint constituted the case group, while those who did not reach any endpoint formed the control group.Results. During the observation period, arrhythmic events were registered in 26 patients (35.1%), with a total of 27.1±13.2 events. Twenty-one patients (28.4%) deceased. In univariate regression analysis, the presence of LGE, the extent of LGE (%), and the number of segments with LGE served as predictors of ICD activation and overall mortality. Two multivariate logistic regression models were constructed. ROC curves were used to determine the quality of the regression model, with an area under the curve of 0.807 for ICD activation and 0.789 for mortality. The highest sensitivity and specificity of the method were observed with a LGE value equal to or greater than 14% for ICD activation (sensitivity 81%, specificity 75%) and 26% for overall mortality (sensitivity 89%, specificity 64%).Conclusion. Substantiated ICD activations (shock/antitachycardia pacing) were observed in 35.1% of cases, and the overall mortality rate was 28.4%. The association between ICD activation and the extent of LGE occurred when LGE was >14%. The association between overall mortality and the extent of LGE occurred when LGE was >26%.

Aim. To evaluate the survival and dynamics of clinical and instrumental data in patients with chronic heart failure (CHF), atrial fibrillation (AF) and cardiac contractility modulation (CCM).Methods. There were included 54 patients (40 men, median age 59.7 [56.6; 63.9] years) with signs of CHF II (n=27, 50%) functional class and III (n=27, 50%) NYHA functional class, significantly decreased left ventricular ejection fraction (LVEF=30 [24,7; 35,5]%), LV dilatation and paroxysmal (n=27, 50%) or permanent (n=27, 50%) AF. In all patients, devices for CCM were implanted. The dynamics of clinical and instrumental parameters were assessed in 2, 6, 12 and 24 months after implantation. The actual survival patients with CCM was compared with the predicted survival calculated using the Seattle model of heart failure and MAGGIC risk score.Results. In 14 (28%) of patients CCM resulted in significantly increased clinical, echocardiographic parameters (increase in LVEF by 15 [11; 20]%, decrease in end-systolic volume by 68,5[37.5;104.5] ml and end-diastolic volume by 44 [30,100] мл), increase in walking distance during 6-minute walking test and decrease of NT-proBNP. The only factor significant for maximal response was non-ischemic etiology of CHF (χ2=4.54, p=0.034). During 2 years 21 (42%) patients died. The all-cause mortality in patients with CCM to the first year of observation was 16%, two-year all-cause mortality - 40%. These figures turned out to be significantly higher than predicted according to the Seattle model (χ2=10.93, p=0.001). The predicted and actual risk of death at 12-month follow-up turned out to be comparable when assessing survival parameters according to the MAGGIC scale. (χ2=2.24, p=0.134).Conclusion. CCM therapy in some patients with CHF of non-ischemic etiology can lead to an improvement of all clinical and instrumental characteristics. At the same time, there is no effect of CCM on the prognosis of patients with CHF. This fact may suggest the need of additional studies with increased number of cases.

Published: June 2024

Aim. To identify noninvasive markers of atrial electrical dysfunction and risk of nonvalvular atrial fibrillation (AF) and to develop a predictive mathematical model to estimate the AF risk based on electrocardiographic (ECG) P-wave parameters during sinus rhythm.Methods. The study included 211 patients with cardiovascular pathology (aged median 62 [52; 71] years, 67.8% male, NYHA heart failure class I-III). All patients (follow-up median 45 [26; 67] months) underwent a complex of studies: 12-lead ECG, echocardiography, 24-hour ECG monitoring. Based on surface ECG data during sinus rhythm, parameters of atrial electrical activation were assessed such as Morphology, Voltage and P waves duration (MVP) according to integral analysis by MVP score.Results. During 3.7-year period, 44 (20.8%) patients experienced new-onset sustained AF and 12 (5.69%) patients developed ischemic stroke. As a result of ROC analysis and univariate Cox regression, independent predictors of AF were identified: P-wave prolongation in the DII lead, 3rd degree or advanced interatrial block (aIAB), an increase P-wave terminal force in lead V1 (PTFV1), low-voltage P-wave in the DI lead and сalculated level of abnormal P-wave ≥3 points on the MVP score. Data from multivariate Cox proportional hazards regression analysis confirmed the prognostic significance for three independent predictors of AF: aIAB (hazard ratio (HR) 5.92; 95% confidence interval (CI) [2.48-4.12]; p=0.0001); PTFV1 (HR 1.14; 95% CI [1.04-1.24], p=0.003); low-voltage P-wave in lead DI <0.1 mV (HR 1.03; 95% CI [1.02-1.05]; p=0.0001); and as a result a mathematical model was created to predict AF risk (-2LL =258; χ2=105; p=0.0001). Predictors such as PTFV1 (HR 1.41; 95% CI [1.17-1.72], p=0.0001) and MVP score of abnormal P-waves (HR 1.85; 95% CI [1.27-1.72] 2.70], p=0.001) were associated with a high risk of stroke according to Cox regression model (-2LL= 62.5; χ2=38.4; p <0.001).Conclusion. Complex of ECG markers of atrial electrical dysfunction such as aIAB, PTFV1, level MVP score of abnormal P-wave and low P-wave voltage allows identifying patients at high risk of AF and ischemic stroke.

Published: June 2024

This study examines the significant role of middle managers and the work environment that promotes knowledge sharing and innovative work behavior in the Thai private sector in Bangkok. Using quantitative research methodology, this study aims to understand how competitive work environments affect middle managers and how middle managers can influence workplace culture to promote knowledge sharing and innovation. The study involved 422 operational employees of enterprises with more than ten employees. The study uses multiple regression analysis to analyze the relationships between variables. The results suggest that while middle managers can play a critical role in facilitating knowledge sharing and innovation, an overly competitive environment can undermine these efforts, highlighting the need for balanced work dynamics. Supportive middle management practices can enhance knowledge sharing and innovation in organizations, but a highly competitive environment may impede these positive outcomes.

Authors: Xiya Han 
Published: June 2024

In 2024, the scale of live streaming e-commerce in China reached 4 trillion yuan, an increase of 47.69% year over year. The market size of China's e-commerce live streaming industry from 2020 to 2023 was 1.5 trillion yuan, 2.2 trillion yuan, 3.5 trillion yuan, and 4 trillion yuan, respectively. Economic data shows that the market size of China's e-commerce live streaming industry has grown rapidly. In the eyes of pragmatic consumers, products with a good brand reputation are worth buying. When consumers encounter products with a good brand reputation and discounts, they often have the impulse to purchase them. Empirical analysis reveals a strong correlation between brand reputation, consumer shopping experience, and impulsive consumption in live streaming contexts. In the context of e-commerce live streaming, both brand reputation and consumer shopping experience can stimulate consumers to engage in impulsive consumption behavior, among which consumer shopping experience has a greater impact on consumer impulsive consumption behavior. When a company enhances its brand reputation and enhances the consumer shopping experience through marketing methods, consumers are more likely to engage in impulsive consumption behavior.

Authors: Song Zhendong 
Published: June 2024

This study, based on self-determination theory and psychological capital theory, aims to explore the relationship between job autonomy, psychological capital, and job crafting behavior among white-collar employees in Chinese enterprises during the VUCA era. Additionally, it examines the mediating role of psychological capital in this context. A questionnaire survey was conducted among 518 Chinese white-collar employees, covering variables related to job autonomy, psychological capital, and job crafting behavior. Hypotheses were formulated based on self-determination theory and psychological capital theory, and statistical analysis was employed to validate the relationships between these hypotheses. The study revealed a positive relationship between job autonomy and job crafting behavior. Job autonomy exhibited a positive influence on psychological capital. Psychological capital also had a positive impact on job crafting behavior. Furthermore, psychological capital is a mediator between job autonomy and job crafting behavior. Based on their research findings, providing recommendations to enhance employees' autonomy in their work contributes to the strengthening of their psychological capital, thereby fostering a greater display of work redesign behaviors. Therefore, organizational managers should prioritize and create a work environment conducive to the development of employee autonomy, aiming to elevate their levels of psychological capital. This, in turn, enables employees to better adapt to and cope with the challenges of the VUCA era.

المستخلص
يلعب القطاع الصناعي دوراً بارزاً في دعم الاقتصاد الوطني في الدول النامية والمتقدمة على حد سواء اذ لابد من تطويره اذا ما ارادت دولة ما الارتقاء الى مصاف الدول المزدهرة اقتصادياً، والعراق من الدول التي مرت بظروف استثنائية القت بظلالها المظلمة على مرافق عدة منها القطاع الصناعي سواء قبل عام 2003 ام بعده بالرغم من توافر الامكانات المادية وتحسن الظروف السياسية التي كان من الاجدر استثمارها بشكل يصب في مصلحة الصناعات الوطنية بشكل خاص واقتصاد البلد بشكل عام .
واذا ما نظرنا عن كثب الى احد محاور القطاع الصناعي وهي الصناعات التحويلية نجد انها عانت كذلك من مشكلات عدة وبكافة تشكيلاتها ومن ضمنها الشركة العامة للصناعات المطاطية والاطارات. هذه المشكلات كانت نتيجة حتمية لما مر به البلد خلال العقود المنصرمة من عدم استقرار الجانب السياسي والحصار الاقتصادي الذي فرض على العراق ليصل الى السياسات العشوائية وانعدام رؤية اقتصادية منطقية تهدف الى النهوض بواقع الصناعات المختلفة التي ممكن ان تكون احد اهم اسباب ازدهار العراق اقتصادياً لما يتمتع بع من مقومات تجعله الافضل من بين دول المنطقة مما ساهم في اضعاف فاعلية هذه الصناعات وضعف انتاجيتها وعدم قدرتها على المنافسة في السوق المحلية .
لذا فقد جاءت هذه الدراسة بفرضية مفادها ان الشركة العامة للصناعات المطاطية والاطارات مع ما تتمتع به مميزات عانت من انخفاض حاد في مستوى الانتاج والايرادات وان التقييم المالي والاقتصادي وفق معايير محددة سوف يساعد على تسليط الضوء على الاسباب التي اوصلت الشركة الى هذه المستويات المتدنية من الانتاج . اما ما تهدف اليه الدراسة فهو تطبيق تلك المعايير على بيانات الشركة لتبيان مواضع الخلل والانحرافات التي من الممكن تجاوزها والنهوض بواقع الشركة والعودة بها الى سوق المنافسة.
واهم ما استنتجت الدراسة هو حاجة الشركة الى رؤية واضحة للسياسات الاقتصادية مع دعم حكومي جاد لكافة مفاصل الشركة والعمل باستراتيجية قادرة على النهوض بهذا القطاع الحيوي . وقد افضت الدراسة الى عدد من التوصيات التي تتناسب وامكانيات العراق المادية ومتطلبات المرحلة، والتي من الممكن ان تساهم في رفع كفاءة الشركة وزيادة نسبة مساهمتها في القطاع الصناعي في العراق وبما يحقق النمو الاقتصادي.

جائحة كورونا وتداعياتها على تغير خارطة توزيع مصادر الطاقة
Authors: علي اكرم نعمة , عبيد علي عباس 
Published: June 2024

ان مفهوم الجائحة يستخدم عندما يصبح الوباء منتشراً بنطاق واسع جداً ولا يمكن السيطرة عليه, ويركز قسم كبير من البحوث التي تقارن بين الأوبئة والجوائح على الإنفلونزا لأنها تحدث بشكل منتظم وموسمي كأوبئة وتتحول في بعض الحالات إلى جائحة, كما أشارت الدراسات عن الأوبئة والجوائح الناجمة عن الأنفلونزا في القرن العشرين إلى أنه من الصعب مقارنة الوباء بالجائحة بسبب التغيرات والتحورات في سلالاته , كما أدت تداعيات الجائحة على قطاع الطاقة إلى إنتشار حالة من الهلع في أسواق الطاقة العالمية, وإن نظام الطاقة العالمي كان الأكثر تضررًا على الإطلاق، وقاد هذا لتقليل الحاجة إلى الطاقة بكافة أنواعها. كما كان لتداعيات جائحة كورونا دور واضح في تغير مزيج الطاقة العالمي, إذ تراجع إنتاج الوقود الأحفوري بشكل كبير ,إذ بلغت نسبة انخفاضه بنحو(5%-) حسب متوسط التغير السنوي لعامي(2020-2019), بعد أن كانت بنحو (%1.9) في (2019-2018), كما تسببت هذه التداعيات بتراجع في الطلب والعرض العالمي لكل أنواع الوقود الأحفوري, ويعد النفط أكثرها تراجعاً إذ بلغت نسبة انخفاضه بنحو(7%-) حسب متوسط التغير السنوي لعامي(2020-2019),أما الغاز الطبيعي ورغم تعافي الطلب في وقت مبكر فقد تراجع الإنتاج بنحو(2.8%-).
