Abstract Background The objective of the current study was to assess the effectiveness of stress management training, grounded in Lazarus and Folkman’s stress management model, on reducing caregiving burden and perceived stress among family caregivers of patients on hemodialysis. Methods This two-group clinical trial study was conducted in parallel design among 60 family caregivers of patients on hemodialysis in 2023. The participants were divided into two groups of training and control using a random quadruple block allocation method. The intervention took place over two months, in six online group sessions of 35–45 min. Zarit Burden Inventory (ZBI) and Cohen’s Perceived Stress Scale (PSS-14) were used to collect information before and two weeks after the intervention. The study data were analyzed using and analysis of covariance (ANCOVA), pair, and independent t-tests at a significance level of 0.05. Results At baseline, the two groups exhibited homogeneity in terms of mean scores for caregiving burden (Training group = 50.8 ± 4.9; Control group = 49.1 ± 6.0; P = 0.264) and perceived stress (Training group = 32.8 ± 4.7; Control group = 31.5 ± 2.4; P = 0.192). Nevertheless, following the intervention, there was a significant decrease in caregiving burden (Training group = 45.9 ± 4.1; Control group = 49.0 ± 5.8; P = 0.017) and perceived stress (Training group = 28.0 ± 4.4; Control group = 30.7 ± 3.5; P = 0.01) scores within the training group compared to the control group. Conclusion Based on the findings of the current study, given that family caregivers of patients on hemodialysis encounter psychological distress and contend with the negative aspects of care, it is advisable to implement psycho-educational interventions, such as stress management training. Incorporating these interventions into the care plan for hemodialysis could help mitigate these adverse consequences and provide valuable support for family caregivers.

Abstract Backscattering is a promising power-efficient communication technique providing sustainable wireless links with a low carbon footprint. This approach is a critical enabler for dense IoT networks, which are forecast to grow to 41 billion by 2025. However, existing backscatter designs are limited to the sub-6 GHz bands or narrowband operation in the millimeter-wave regime; therefore, they fail to concurrently support many interference-free low-power users. Enabling a frequency-agile wideband backscatter design in the sub-terahertz offers a two-pronged advantage for densely deployed backscatter networks: spatial reuse enabled by directionality and frequency multiplexing enabled by the large available bandwidth. We present the first sub-THz backscatter architecture that operates above 100 GHz. Our design relies on a detailed understanding of reciprocity in leaky-wave devices and offers a realistic joint localization and communication protocol for sub-THz backscatter networks.

Abstract Background The presence of cardiac myxoma in the right atrium (RA) is rare. There is limited knowledge regarding the clinical symptoms and diagnosis of RA myxoma. This systematic review aimed to provide a summary of the clinical and laboratory characteristics, electrocardiogram (ECG) findings, and outcome previous cases with RA myxoma. Methods A comprehensive search was conducted in PubMed, Web of Science, and Scopus to identify relevant studies. Inclusion criteria were case reports and case series written in English that provided sufficient data on the manifestation of RA myxoma. Descriptive statistics were used for quantitative analysis. Results The search identified 619 patients from 480 eligible studies. The patient’s mean age was 45.7 ± 17.6 years, and 55.4% of cases were female. The most common clinical manifestations of RA myxoma were cardiac, systemic, and neurologic manifestations which reported in 77.0%, 34.8%, and 21.1% of cases, respectively. Besides, 11.7% of RA myxoma were asymptomatic. ECG findings revealed normal in 39.4% reported cases. The ECG abnormalities included tall or peaked P-wave, RA and LA enlargement (19.2%), abnormal T-wave (14.0%), sinus tachycardia (11.8%), and incomplete or complete RBBB (11.2%). Echocardiography remained the diagnostic method in a majority of the cases. The mortality rate of RA myxoma was low (9.2%) during the follow-up. Conclusions This systematic review provides a comprehensive summary of the clinical and laboratory manifestations and outcomes of RA myxoma, contributing to the existing knowledge on this rare cardiac tumor.

As the demand for edible oil continues to soar, rapeseed cultivation remains pivotal for sustainable and efficient oil production, catering to the nutritional needs of a burgeoning population. Given the substantial impact of environmental stress on plant productivity, this study aimed to explore the in vitro responses of calli-derived hypocotyls from five Brassica napus genotypes under varying concentrations of polyethylene glycol (PEG) 6000 (0%, 10%, 20%, 30%, and 40%). The objective was to assess various growth and physiological parameters, including Callus Growth Rate (CGR), Relative Water Content (RWC), Index of Tolerance (INTOL), Relative Growth Rate (RGR), and Proline Content (PC). Results unveiled a significant surge in proline content with increasing levels of PEG, with the highest accumulation observed at 40% PEG concentration. These findings suggest that heightened osmotic stress induced by PEG led to a notable rise in proline accumulation in calli-derived hypocotyls. Furthermore, elevated levels of PEG-induced osmotic stress adversely impacted growth parameters such as RWC, RGR, and CGR. Notably, genotypes Geronimo and Arc5 exhibited enhanced drought resistance in in vitro environments compared to other genotypes. These particular genotypes showcased greater resilience and adaptability to PEG-induced osmotic stress, as evidenced by significantly higher measurements of relative water content (RWC), relative growth rate (RGR), and Callus Growth Rate (CGR). Physiological indices like Relative Water Content (RWC), Relative Growth Rate (RGR), and Callus Growth Rate (CGR) offer valuable insights into a plant's response to environmental stresses like water scarcity. This selection process is crucial for developing more resistant plant varieties that thrive even in challenging environmental conditions.

Background: Intensive maternal parenting, while intended to foster academic achievement, has been linked to increased stress and anxiety in children. The present study aimed to investigate the mediating role of maternal mental health in the correlation between intensive maternal attitudes and cognitive abilities in female students applying for the gifted exam.Methods: The study employed a descriptive cross-sectional approach that incorporated the use of structural equation modeling (SEM) techniques. The target population comprised all female students applying for the ninth-grade gifted exam in Tehran, Iran during 2023, along with their mothers. A convenience sample of 301 student-mother dyads participated in the study by completing a battery of self-report questionnaires. These instruments included Cognitive Abilities Questionnaire (CAQ), Intensive Parenting Attitudes Questionnaire (IPAQ), and General Health Questionnaire (GHQ-28). The hypothesized model was evaluated using SEM, and bootstrapping was employed to assess the significance of indirect correlations. Statistical analyses were performed using SPSS version 27 and Amos version 25.Results: The findings indicated a negative correlation between intensive maternal attitudes and students’ cognitive capabilities (P=0.020). There was also a significant negative correlation between intensive maternal attitudes and mothers’ mental health (P=0.001). The correlation between mothers’ mental health and girls’ cognitive abilities was positive and significant (P=0.001). The correlation between intensive maternal attitudes and students’ cognitive abilities was significant through the mediating role of mental health (P=0.005).Conclusion: Intensive maternal parenting practices were associated with decreased cognitive abilities in students and poorer mental health in mothers. The negative effect of intensive maternal attitudes on cognitive abilities appears to be indirectly mediated by mothers’ mental health.

In the past decade, research on EFL teachers’ beliefs about translanguaging has significantly grown. However, little qualitative research has been done on teachers’ translanguaging beliefs and practices and the congruity between them. To address this gap in the literature, the current study investigated Iranian EFL teachers’ beliefs and practices, and the correspondence between these beliefs and practices. Data was collected from ten teachers who taught English as a foreign language through semi-structured interviews and classroom observations (three per teachers). The data was analyzed based on the principles of thematic analysis. The results showed that the teachers perceived six dimensions of translanguaging, including diverse beliefs of translanguaging, perceived relevance of translanguaging, pedagogical beliefs and approaches, attitudes toward benefits, concerns and challenges of applying translanguaging, and student-centered approaches. In regard to their practice, the teachers practiced translanguaging in various contexts and through different instructional strategies in their classes. Regarding the correspondence between beliefs and practices, it was found that there was a mainly direct correspondence between beliefs and practices. The study provides implications for teacher educators in running professional development courses that enhance teachers’ awareness of using translanguaging in their classes.

Objectives: Patients experience complications following their recovery from COVID-19, known as post-COVID-19. This study aimed to investigate the association between baseline socioeconomic status (SES) and post-COVID-19 symptoms among hospitalized and non-hospitalized patients. Methods: In the study, we used data from the Isfahan COVID Cohort (ICC) study, a 5-year longitudinal cohort study started from March 10, 2020. SES was measured using short form of SES questionnaire (SES-SQ), consisting of employment status, house room number, the number of trips taken, and using notebooks, laptop, or tablet in the house. Cox proportional hazard analysis was used to examine the association between baseline SES and post-COVID-19 symptoms including general, cardiovascular and respiratory systems, adjusting for potential confounders. Results: Out of the 3912 patients included in the study, 66.4 % reported post-COVID-19 symptoms. There was an association between low SES and increased risk of post-COVID-19 cardiovascular symptoms in the whole population (HR = 1.15; 95 CI, 1.01–1.31, p = 0.039). Considering the hospitalization status revealed that hospitalized patients with low SES had a higher risk of experiencing post-COVID-19 cardiovascular symptoms (HR = 1.96; 95 CI, 1.23–3.12, p = 0.004), while in non-hospitalized, low SES patients a lower risk was observed (HR = 0.82; 95 CI, 0.70–0.97, p = 0.017). No significant association was found between SES and other post-COVID-19 symptoms including general and respiratory symptoms. Conclusions: We concluded an association between higher SES and increased post-COVID-19 cardiovascular symptoms. Low SES was associated with higher risk of post-COVID-19 cardiovascular symptoms in hospitalized patients, while in non-hospitalized, it was associated with a lower risk.

Abstract Background Nurses’ professional competencies play a significant role in providing safe care to patients. Identifying the acquired and expected competencies in nursing education and the gaps between them can be a good guide for nursing education institutions to improve their educational practices. Methods In a descriptive-comparative study, students’ perception of acquired competencies and expected competencies from the perspective of the Iranian nursing faculties were collected with two equivalent questionnaires consisting of 85 items covering 17 competencies across 5 domains. A cluster sampling technique was employed on 721 final-year nursing students and 365 Iranian nursing faculties. The data were analyzed using descriptive statistics and independent t-tests. Results The results of the study showed that the highest scores for students’ acquired competencies and nursing faculties’ expected competencies were work readiness and professional development, with mean of 3.54 (SD = 0.39) and 4.30 (SD = 0.45), respectively. Also, the lowest score for both groups was evidence-based nursing care with mean of 2.74 (SD = 0.55) and 3.74 (SD = 0.57), respectively. The comparison of competencies, as viewed by both groups of the students and the faculties, showed that the difference between the two groups’ mean scores was significant in all 5 core-competencies and 17 sub-core competencies (P

Abstract Background Academic procrastination is a widespread phenomenon among students. Therefore, evaluating the related factors has always been among the major concerns of educational system researchers.

Abstract Background Resilience and self-efficacy play an influential role in nurses’ clinical performance, which are considered resources for improving adaptability and promoting work engagement. This study aimed to determine the relationship between resilience and self-efficacy among nurses at Shahroud University of Medical Sciences hospitals during the post-Corona era. Methods This cross-sectional study was conducted on 280 nurses in all clinical departments. Nurses with a bachelor of science in nursing or higher degree and at least one year of full-time work experience were included in the study using a convenience sampling method. Participants completed a three-part tool, which included the demographic information form, the Connor-Davidson Resilience Scale, and the General Self-Efficacy Scale. The data were analyzed using descriptive statistics and inferential tests (multivariate linear regression using the backward method). Results In this study, nurses reported low levels of resilience (63.64 ± 15.66) and high levels of self-efficacy (63.01 ± 9.57). Among the five resilience subscales, the highest mean item score was associated with “spiritual influences” (2.80 out of 4), while the lowest mean item score was associated with “trust in one’s instincts and tolerance of negative affect” (2.36 out of 4). Furthermore, the multivariate linear regression model results indicated that self-efficacy accounted for 33.6% of the variance in resilience (P

Abstract Background Atherogenic index of plasma (AIP) represents a novel marker in the current era of cardiovascular diseases. In this meta-analysis, we aimed to evaluate the association of AIP with cardiovascular prognosis in patients with coronary artery disease (CAD). Methods PubMed, Scopus, and Web of Science databases were searched from inception through 2024. The primary outcome was major cardiovascular events (MACE). The secondary outcomes included all-causes death, cardiovascular death, myocardial infarction (MI), stroke, revascularization, and no-reflow phenomenon. AIP was determined by taking the logarithm of the ratio of triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C). The data analysis was represented using the risk ratio (RR) along with a 95% confidence interval (CI). Results Sixteen studies with a total number of 20,833 patients met the eligible criteria. The pooled-analysis showed a significant increased risk of MACE in the highest AIP group compared with the lowest AIP group (RR = 1.63; 95% CI, 1.44–1.85; P

Self-wanted isolation is considered a silent phenomenon of the organization; A situation where the employee deliberately chooses a secluded corner and does not throw itself away from events and events and does not allow participation in organizational activities. self-wanted isolation from the employees' perception of the poor performance of the supporting role by the organization; atmosphere and unhealthy competition among colleagues has arisen, which leads the individual to leave the job after failing to use other behavioral strategies and despairing of leaving the job. Undiscovered dimensions and causes from researchers' point of view and hidden from managers' view led to the necessity of conducting research. Therefore, this research seeks to understand the conceptual depth and causal factors of this little-known phenomenon in Iran's administrative system. This research follows qualitative methodology And from the perspective of strategy, it is based on the data theory of the foundation. The statistical population consisted of experts working in government organizations in Ilam city, which was conducted in the form of theoretical sampling, taking into account the theoretical saturation base, with a number of 17 semi-structured interviews. Reliability of qualitative data was measured through the criteria of Lincoln and Guba (1985). Finally, delving into the depth of the data led to the emergence of 5 categories Organizational poisoning, The traditional form of the organization, Inefficiency of administrative processes, Experienced bitterness and organizational culture and atmosphere as causes of self-wanted isolation with other markers of phobia, silent protest, She had idealistic expectations and a conservative attitude

Breast cancer anti-estrogen resistance-1 (p130Cas/BCAR1) is an adaptor protein of the cas(Cas) family. This protein regulates multiple complex pathways in different organs including bones, pancreas, and immune and cardiovascular systems. Although previous research well demonstrated the role of p130Cas/BCAR1 in different diseases especially cancers, a precise review study on the various effects of p130Cas/BCAR1 on cardiovascular diseases is missing. In this study, we reviewed mechanisms of action for p130Cas/BCAR1 impact, on cardiac embryonic development defects, hypertrophy and remodeling, pulmonary artery hypertension (PAH), and atherosclerosis. Also, we suggest feature direction for research and potential therapeutic implications. This study showed that p130Cas/BCAR1 can affect cardiovascular diseases in various mechanisms including actin stress fiber formation, attachment to focal adhesion kinase (FAK) and angiotensin II (Ang II), generation of reactive oxygen species (ROS), and growth factor signaling through amplifying receptor tyrosine kinase (RTKs).

The migration of vascular smooth muscle cells (VSMCs) is one of the most important events in the remodeling of atherosclerosis plaque. The aim of study was to investigate the role of Heparin in the VSMC migration and its association with the NF-kB, collagen 1 and collagen 3 expression levels. Moreover, the incorporation of Heparin was studied in the VSMC cultures including Betulinic acid and Ibrutinib. Twelve cell groups were cultured and treated with the Heparin, Betulinic acid and Ibrutinib based on the viability and toxicity in 24-h and 48-h periods. The gene and protein expression levels were measured by RT-qPCR and western blotting techniques. The VSMC migration was determined by scratch test. In contrast with Ibrutinib (2 μM), Heparin (30 IU) increased significantly (P

Aim and IntroductionOrganizations locked in the iron fence of rules and regulations require their members to act only within the delineated limits so as to be less involved with intellectual challenges. Over time, this issue leads to the formation of presuppositions and attitudes in the minds of employees and, as a result, behaviors that show resistance against any kind of disruptive change in the existing conditions; And without thinking and understanding the change of conditions, they act according to what they have learned so far. In such a situation, people will be inflexible against new events and even their abilities will act as potential obstacles. In addition to the fact that this method of action is the result of consecration of laws and regulations, protection of job security and fear of closing job career for promotion, as well as taking care of the safe margin around oneself and fear of failure; The result is getting caught in the competence trap.In the category of degenerate competences, employees with rusty beliefs, frozen thoughts, improper context and familiar actions are watching their office life pass. The captives insist on their path as if the only way to achieve excellence is to flow through it, and any look other than theirs is met with visible and hidden resistance. Therefore, the present research aims to scrutinize the antecedents of the competency trap and reveal its consequences from the experts' point of view.MethodologyThis research is exploratory in nature, and in order to understand the antecedents and consequences, it has explored the experiences of 16 employees of public organizations in Ilam city by using a random sampling method until reaching theoretical saturation. The data is based on the open, axial and selective coding method, combining the terms used by the participants themselves; Analysis and finally the categories and components are obtained. In this way, after conducting the interview, open codes are extracted and then by merging and integrating the open codes, the axial codes are determined. MAXQDA 2020 software was used for data analysis. Then, the components were prioritized using the fuzzy Delphi method. FindingsThe components identified in the interview stage are provided to the experts in the form of a questionnaire, and according to the proposed option and the defined linguistic variables, the results of the examination of the answers given in the questionnaire are analyzed to obtain the fuzzy average of the components. According to the views presented in the first stage and comparing it with the results of the second stage, the difference between the de-fuzzified average in the two stages was less than 0.1, in this case the survey process was stopped and prioritization was done. According to the findings, traditional management style, technology phobia and administrative socialization respectively had the greatest share in development of competence traps from the experts' point of view. Also, according to the experts, The consequences such as outdated knowledge, job routine and job satisfaction respectively have a stronger role as a result of competency traps in the public organizations in Ilam city. Discussion and Conclusion It can be difficult to let go of traditional beliefs and knowledge, especially when one's colleagues and managers of an organization argue against it or even challenging the new knowledge and theory. This is where the competency trap in the organization gains more strength and power due to the circle of decision-making power as well as groupthink. Sometimes, we have to let go of what we thought was right, but sometimes conditions and mechanisms like a wave drown a person in a flood of intellectual stagnation, and minds do not grow with the passage of time, and a miniature of old stereotypes and memory will be archived. The competency trap creates a knowledge gap in employees because they are under the shadow of what they know. Considering that knowledge, skill and competence is a potential power, which in incorrect application, diminishes its awe and admiration and leads to a competence trap that deceives the mind and gradually, exhaustion and organizational decline are revealed. The results of this research lead to the discovery and explanation of the lesser-known phenomenon of competency traps in the geometry of human resource management studies in the country and provide a clear path to managers and policy makers of the administrative system in understanding the said phenomenon and how to deal with it.

The purpose of this research is to identify the influencing factors on users' continuous use of e-reader applications. For this purpose, the proposed hybrid model based on the Theory of Expectation-Confirmation, Davis's Technology Acceptance Model, and Perceived Playfulness Theory have been used. Methodology: The current research is applied in terms of purpose and survey type. The research population includes students who use e- reader applications (Taqcheh, Fidibo, Ketab Rah, and Ketab Sabz). Among them, 300 active users of the mentioned readers were selected as the statistical sample of the research. The data collection tool is a questionnaire. This questionnaire is taken from a research in English, which was translated into Persian by the authors of this article. Therefore, in order to ensure the clarity of the questions and the correctness of the translation, its validity and ending were re-evaluated by the authors. In order to measure the validity of the questionnaire, the opinions of 5 experts and managers of e-reader programs as well as professors of information science who have scientific publications in the field of technology acceptance were obtained and applied. Next, to measure the reliability, a preliminary study was conducted with the participation of 30 people from the research community and the value of Cronbach's alpha coefficient was calculated, and the value of 0.908 (9.08%) showed that the measurement tool has a suitable and desirable reliability. The collected data were analyzed using the structural equation modeling method. For data analysis, use SPSS Version 25 and Amos version 22 were used. Findings: The research findings showed that the personalization of e-reader applications has a significant effect on the perceived usefulness of users. Also, the personalization of e-reader applications has an effect on the Perceived Playfulness of users. Among other findings of this research, we can mention the significant effect of usefulness and Playfulness of e-reader applications on user satisfaction. The effect of user satisfaction on the use of e-reader applications was also reported to be significant. According to the mentioned cases, all the hypotheses of this research were confirmed. Conclusion: Although more than a decade has passed since the emergence and use of electronic readers in the world, the use of this technology in Iran has been growing gradually in recent years. According to the results of this research and considering the competition of manufacturing companies, manufacturers are expected to consider aspects of personalization, playfulness, usefulness, and user satisfaction in designing e-reader applications. In this regard, a detailed study of the users of e-reader applications with an emphasis on age, gender, education and occupation, as well as knowing their reading needs, can help managers to know more about the design of user-friendly applications and make users continue to use them.

Abstract In this paper, we theoretically study the enhancement of third-harmonic generation in a plasmonic structure composed of an array of trilayer graphene ribbons sandwiched between two $$CaF_{2}$$ C a F 2 layers. In fact, we suggest a new method for more enhancement of nonlinearity in plasmonic structures using incorporation of optical gain into graphene ribbons. As the pump intensity increases, the maximum output intensity of third harmonic generated (THG) wave versus fundamental frequency is blue-shifted while its value enhances. Our analysis indicates that the enhancement factor of THG in our proposed structure is 1.1 × 107 without occurring an electric breakdown compared to case at which an optically pumped trilayer graphene sheet sandwiched between two CaF2 layers. Therefore, only presence of optical gain is not sufficient for significant enhancement of output intensity of THG wave and excitation of SPPs through the structure is also essential. On the other hand, our results demonstrate that the output intensity of THG wave from the proposed structure under optical pumping enhances by $$10^{5}$$ 10 5 times compared to the plasmonic structure without optical gain which confirms the role of optical gain for THG enhancement in the plasmonic structure. This is because the gain in graphene ribbons amplifies the SPPs waves leading to the more field enhancement along the graphene ribbons which results in significant enhancement of THG wave in the plasmonic structure in comparison with one without gain. Therefore, we reveal that both SPPs and optical gain contribute to the strong output intensity of THG in our proposed structure compared to the trilayer graphene sheet inserted between two CaF2 layers.

Introduction: Postpartum hemorrhage (PPH) is one of the main causes of maternal mortality. The present study was conducted with aim to investigate the relationship between low levels of fibrinogen and the severity of PPH and the importance of administering fibrinogen concentrate or cryo to reduce bleeding.Methods: This prospective cohort study was conducted from 2017 to 2019 on 122 mothers with uterine bleeding in the first 24 hours after delivery in Mashhad. In case of persistent bleeding and rejection of traumatic causes, misoprostol was prescribed, and blood samples were taken at this time (time H0). Patients were divided into severe and non-severe groups by considering the severity of bleeding from H0 to 24 hours. Data were analyzed by SPSS software (version 16) and independent t-test and Mann-Whitney, paired t, Chi-square and Fisher's tests. P

Video streaming has become an integral part of our digital lives, driving the need for efficient video delivery. With the growing demand for seamless video delivery, adaptive video streaming has emerged as a solution to support users with varying device capabilities and network conditions. Traditional adaptive streaming relies on a predetermined set of bitrate-resolution pairs, known as bitrate ladders, for encoding. However, this “one-size-fits-all” approach is suboptimal when dealing with diverse video content. Consequently, per-title encoding approaches dynamically select the bitrate ladder for each content. However, in an era when carbon dioxide emissions have become a paramount concern, it is crucial to consider energy consumption. Therefore, this paper addresses the pressing issue of increasing energy consumption in video streaming by introducing a novel approach, ESTR, which goes beyond traditional quality-centric resolution selection approaches. Instead, the ESTR considers both video quality and decoding energy consumption to construct an optimal bitrate ladder tailored to the unique characteristics of each video content. To accomplish this, ESTR encodes each video content using a range of spatial and temporal resolutions, each paired with specific bitrates. It then establishes a maximum acceptable quality drop threshold ( $\tau $ ), carefully selecting resolutions that not only preserve video quality above this threshold but also minimize decoding energy consumption. Our experimental results, at a fixed $\tau $ of 2 VMAF steps, demonstrate a 32.87% to 41.86% reduction in decoding energy demand for HEVC-encoded videos across various software decoder implementations and operating systems, with a maximum bitrate increase of 2.52%. Furthermore, on a hardware-accelerated client device, a 46.37% energy saving was achieved during video playback at the expense of a 2.52% bitrate increase. Remarkably, these gains in energy efficiency are achieved while maintaining consistent video quality.
