Wu YY, Li JY, Xia QJ, Gao YY, Zhang C, Xu PJ, Liu J, Zhang HJ, Yu RZ. Analysis of Risk Factors of Sarcopenia in Patients with Maintenance Hemodialysis and Its Correlation with Emotional Status and Quality of Life. J Multidiscip Healthc 2024; 17:3743-3751. [PMID: 39104383 PMCID: PMC11299645 DOI: 10.2147/jmdh.s469900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Accepted: 06/21/2024] [Indexed: 08/07/2024] Open
Abstract
Objective Sarcopenia is more common in maintenance hemodialysis (MHD) patients, and the aim of this study is to analyze the risk factors associated with sarcopenia in MHD patients, along with its correlation to emotional status and quality of life. Methods This is a cross-sectional cohort study. A total of 111 MHD patients who were treated in the Department of Nephrology of our hospital were selected as the study subjects by convenience sampling. The quality of life and emotional status were evaluated by health survey scale (SF-36), self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Regression analysis was used to explore the influencing factors of sarcopenia. Correlation analysis was used to investigate the correlation between sarcopenia and quality of life and emotional status. Results The prevalence of sarcopenia was 59.8%. The results showed that age, gender, body mass index (BMI), dialysis time, economic status, marital status and pre-dialysis creatinine were significant factors affecting the development of sarcopenia in hemodialysis patients (p<0.05). The SF-36 total score was significantly lower in the sarcopenia group (72.05±12.28 vs 78.03±10.55) than in the non-sarcopenia group, but the anxiety scale score (52.97±4.67 vs 36.2±3.36) and depression scale score (57.67±4.58 vs 38.71±3.77) were significantly higher than those in the non-sarcopenia group (p< 0.001). Correlation analysis showed that sarcopenia was positively correlated with SAS and SDS scores and negatively correlated with SF-36 total score (p < 0.05). Conclusion The risk of sarcopenia was higher among MHD patients who were older, male, single, with a longer MHD duration, lower economic status, lower BMI, comorbid diabetes and lower levels of creatinine.

Abstract
Objective To investigate the association of mental and oral health with the health-related quality of life (HRQOL) in patients with cancer and cancer survivors. Methods This cross-sectional study involved 1643 patients with cancer and 1628 individuals who survived cancer (aged ≥ 19 years) using data from the 2005-2018 Korean National Health and Nutrition Examination Survey. The data were analyzed using SAS survey procedures (version 9.4), t-tests, χ2 test, and multiple regression. Results Regarding differences in mental and oral health factors by group, the results revealed significant differences between depression, suicidal ideation, subjective oral health, chewing problems, and speaking problems due to oral issues. The HRQOL of patients with cancer was lower than that of cancer survivors. The factors influencing HRQOL in both patients with cancer and cancer survivors were education status, economic activity, subjective health, suicidal ideation, and speaking problems due to oral issues. HRQOL was also associated with depression in patients with cancer. Conclusions Patients with cancer had a lower HRQOL than cancer survivors. The two groups of patients showed significant differences in the factors associated with HRQOL. Therefore, customized health programs and policies should be developed and implemented for each group to improve their QOL.

Abstract
Emotional Intelligence (EI), defined as the ability to perceive, identify, understand, and regulate emotional states is related to health outcomes. In this line, some studies examined this personal resource in the cancer area and, specifically, in breast cancer. Also, the different models and measures have led to a categorisation considering the various construct-method pairings of EI. Despite the increased number of studies about EI in the breast cancer context, there are no systematic reviews that summarise the results obtained in the different investigations. Objectives: Hence, the present review aims: to identify and describe the measures that have been used for assessing EI within this field, and to summarise the main results regarding EI in terms of its predictors and outcomes, considering the instruments used to assess it. Methods: The PRISMA guidelines were followed. Database search was conducted in WOS, Scopus, Pubmed, and PSYCArticles. Results: A total of 156 articles were found and 21 met the eligibility criteria. On one hand, one of the most used instruments was the TMMS-24 framed within the self-report ability EI, followed by those framed within the self-report mixed EI. None of the studies measured EI by the performance-based ability EI perspective. On the other hand, EI was related to other variables such as psychological well-being, quality of life, resilience, workability, anxiety, and depression. The majority of the studies were cross-sectional, and some of them included an intervention. Conclusions: This review provides a comprehensive overview of the existing studies concerning EI in the context of breast cancer, highlighting some of its characteristics regarding design, participants, used measures, and related variables. Also, the obtained results can improve the clinical practice and the understanding of the EI as an influencing factor in the health and quality of life of breast cancer populations.

Abstract
BACKGROUND Family caregivers of cancer patients must have strong emotional intelligence skills essential for understanding one's and others' feelings and learning how to cope. OBJECTIVES The present study aims to determine the predictive factors of emotional intelligence and its relationship with spiritual intelligence, coping, and knowledge and experience about pain among family caregivers of cancer patients in Iran. METHODS A cross-sectional, descriptive study was conducted in 2020-2021. Two hundred twenty-six family caregivers of cancer patients participated in this study. The data collection tools were Wong and Law's emotional intelligence, King's spiritual intelligence, Brief Cope, and the family pain questionnaire. Following determining the variables' correlation, linear regression was carried out. RESULTS Emotional intelligence had a significant correlation with age (r = 0.20, p = .003), academic degree (r = 0.15, p = .032), duration of care (r = 0.15, p = .032), and spiritual intelligence (r = 0.30, p < .001). The regression model accounted for 12.4% of the variance in emotional intelligence; age (β = 0.16, p < .021) and spiritual intelligence (β = 0.26, p < .001) were significant explanatory variables. CONCLUSIONS Emotional intelligence is correlated with age, academic degree, duration of care, and spiritual intelligence, but only age and spiritual intelligence were found to be predictive factors for emotional intelligence in the family caregivers of cancer patients.

Abstract
Background For individuals living with chronic conditions like diabetes mellitus and obesity, there is a need for sustainable behavioral strategies and physiologic tools. These tools support identifying and addressing barriers to healthy eating, reducing body mass index (BMI), and building increased physical resilience in real time. Objective To evaluate whether a 12-week learning management system designed to combine nutritional intervention with education and coaching on improving emotional intelligence (EI) could alter cardiometabolic outcomes. Methods This pre-post prospective study enrolled 37 adult volunteers with BMI greater than 25 to participate in a 12-week learning management system. Primary (BMI, systolic blood pressure, diastolic blood pressure, low-density lipoprotein [LDL], high-density lipoprotein, and fasting glucose levels) and secondary self-reported outcomes were assessed at baseline, 12 weeks, and 6 months after enrollment using Short Form-36, Emotional Quotient Inventory (EQi), and Whole Health Index (WHI). Linear mixed-effects regression models with random effect were used to estimate changes in primary and secondary outcomes. We adjusted for multiple testing using Holm step-down method. Results BMI and LDL were the only primary endpoints lower at program completion and 6-month follow-up compared to baseline levels (-1.63 and -17.77 mg/dL, respectively; P < .001). Secondary outcomes showing statistically significant improvement from baseline to 6-month follow-up included energy/fatigue (Short Form-36), self-regard (EQi), decision-making (EQi), impulse control (EQi), stress management (EQi), Whole Brain - Form A (WHI), Whole Food - Form C (WHI), and Whole Body - Form D (WHI). Conclusion This study provides preliminary evidence that lifestyle programs combining nutritional interventions and EI can have a significant impact on BMI and LDL. Our study highlights the potential importance of both nutrition and EI in programs targeting diet and lifestyle modification.

Abstract
AbstractPain catastrophizing (PC) is a negative cognitive distortion to actual or anticipated pain. This study aims to investigate the relationship between pain catastrophizing, emotional intelligence, pain intensity, and quality of life (QoL) in cancer patients with chronic pain. Eighty-nine outpatients with chronic pain attending pain clinics and palliative care units were recruited. Participants were men (42.7%) and women (57.3%) with an average age of 56.44 years (SD = 14.82). Self-report psychological measures were completed, including a measure of emotional intelligence, a standard measure of PC, a scale assessing pain intensity, and a scale measuring QoL. The PC scale was found to assess three correlated yet different dimensions of pain catastrophizing (helplessness, magnification, and rumination). Moreover, as expected, patients with PC scale scores ≥ 30 had lower scores in functional QoL dimensions and higher scores in the fatigue, pain, and insomnia symptom dimensions. Regression analyses demonstrated that PC (B = − 0.391, p = 0.004), pain intensity (B = − 1.133, p < 0.001), and education (B = 2.915, p = 0.017) remained the only significant variables related to QoL, when controlling for demographic and clinical confounders. Regarding mediating effects, PC and pain intensity were jointly found to be significant mediators in the relationship between emotional intelligence and QoL. Results are discussed in the context of the clinical implications regarding interventions designed to improve cancer patients’ quality of life and offer new insight, understanding, and evaluation targets in the field of pain management.

Abstract
Purpose: Participants’ engagement in a project requires intrinsic motivations, which may evolve during the intervention thanks to lifestyle changes and positive challenges. Over the years, tailored programs based on physical activity and psychological sessions have been promoted to support the quality of life and well-being of breast cancer survivors. Personal expectations and needs are essential to predict participant adherence to the intervention as well as their possibility to reach positive outcomes. This study presents a preliminary understanding of the differences between motives and outcomes obtained after an integrated physical and psychological intervention conducted by professional trainers and psychologists. Methods: Forty-five women with a history of breast cancer answered some questions before and after the program, and the results were analyzed in accordance with the procedure of the thematic analysis. Results: Physical and psychological well-being are the two main themes that emerged from the participants. Interestingly, some differences emerged between the two data collections. Themes such as aesthetic evaluation interest and the need to learn psychological strategies disappeared at the end of the intervention; on the other hand, the need to make a distance from the illness experiences emerged as an obtained outcome. Conclusions: The discussion explains these differences and highlights the importance of considering breast cancer patients’ needs and motives to take part in interventions to promote quality of life.

Abstract
Breast cancer is the malignancy with the highest incidence in women worldwide. The empirical evidence is inconsistent with the prevalence of depression among breast cancer survivors (BCS), pointing to emotional competencies as protective factors against affective disorders. However, the mechanisms through which these competencies favor a more adaptive emotional state are unknown. Therefore, this study aims to explore the relationship between the experience of having survived the disease and depression levels in a group of BCS, and the mediating role of Perceived Emotional Intelligence (PEI) in this relation. This was a cross-sectional study with 237 women divided into two groups: 56 BCS and 181 healthy controls who completed the Trait Meta-Mood Scale 24 (TMMS-24) and the Hospital Anxiety and Depression Scale (HADS). Results showed that Survivorship and PEI explained and predicted 37.8% of the variance of depression, corresponding the 11.7% to the direct and/or the indirect effect of the PEI dimensions (Emotional Attention, Emotional Clarity, and Emotional Repair). In conclusion, interventions aimed at promoting an adequate PEI in this population-and in the Psycho-oncology field, in general-with a particular focus on the development of Emotional Clarity and Repair need to be implemented. Limitations and future research lines are discussed.

Abstract
INTRODUCTION Emotional Intelligence (EI) is a well-documented aspect of social and interpersonal functioning, but the underlying neural mechanisms for this capacity remain poorly understood. Here we used advanced brain connectivity techniques to explore the associations between EI and effective connectivity (EC) within four functional brain networks. METHODS The Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) was used to collect EI data from 55 healthy individuals (mean age = 30.56±8.3 years, 26 males). The MSCEIT comprises two area cores - experiential EI (T1) and strategic EI (T2). The T1 core included two sub-scales - perception of emotions (S1) and using emotions to facilitate thinking (S2), and the T2 core included two sub-scales - understanding of emotions (S3) and management of emotions (S4). All participants underwent structural and resting-state functional magnetic resonance imaging (rsfMRI) scans. The spectral dynamic causal modeling approach was implemented to estimate EC within four networks of interest - the default-mode network (DMN), dorsal attention network (DAN), control-execution network (CEN) and salience network (SN). The strength of EC within each network was correlated with the measures of EI, with correlations at pFDR < 0.05 considered as significant. RESULTS There was no significant association between any of the measures of EI and EC strength within the DMN and DAN. For CEN, however, we found that there were significant negative associations between EC strength from the right anterior prefrontal cortex (RAPFC) to the left anterior prefrontal cortex (LAPFC) and both S2 and T1, and significant positive associations between EC strength from LAPFC to RAPFC and S2. EC strength from the right superior parietal cortex (SPC) to RAPFC also showed significant negative association with S4 and T2. For the SN, S3 showed significant negative association with EC strength from the right insula to RAPFC and significant positive association with EC strength from the left insula to dorsal anterior cingulate cortex (DACC). CONCLUSIONS We provide evidence that the negative ECs within the right hemisphere, and from the right to left hemisphere, and positive ECs within the left hemisphere and from the left to right hemisphere of CEN (involving bilateral frontal and right parietal region) and SN (involving right frontal, anterior cingulate and bilateral insula) play a significant role in regulating and processing emotions. These findings also suggest that measures of EC can be utilized as important biomarkers to better understand the underlying neural mechanisms of EI.
