Hopelessness and Depression Predict Sarcopenia in Advanced CKD and Dialysis: A Multicenter Cohort Study

The influence of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life of patients with sarcopenia receiving haemodialysis: a randomised controlled trial

OBJECTIVE

To study the effect of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life in patients with sarcopenia receiving maintenance haemodialysis (MHD).

METHODS

Eligible patients with sarcopenia in our hospital were randomly assigned to a control group (n = 24) and an intervention group (n = 25). The control group received conventional dialysis treatment, while the intervention group underwent mindfulness meditation combined with progressive muscle relaxation training during the interdialysis period in addition to conventional dialysis treatment. The effect of the intervention was evaluated after 12 weeks.

RESULTS

There were no significant differences in the baseline values of various parameters between the two groups. Exercise capacity (sit-to-stand test,handgrip,time to 10 sit-ups) significantly improved in the intervention group after 12 weeks (32.68 ± 8.32 vs 26.50 ± 6.83; 37.42 ± 10.12 vs 28.12 ± 8.51; 19.8 ± 5.40 vs 25.29 ± 7.18) (p < 0.05). In terms of the kidney disease quality of life (KDQOLTM) score, all other dimensions except sexual function, social functioning, burden of kidney disease and work status dimensions showed significant improvement compared to the baseline (p < 0.05). In the control group, only the dialysis staff encouragement (DSE) and patient satisfaction (PS) dimensions showed slight improvements compared to the baseline (p > 0.05). When compared with the control group, the intervention group showed significant improvements in 10 dimensions of exercise capacity and KDQOLTM scores for physical function, role-physical, general health, energy, symptom/problem list, sleep, DSE, pain, cognitive function, emotional well-being and patient PS after 12 weeks (61.30 ± 5.38 vs 42.98 ± 5.73; 57.50 ± 3.55 vs 50.70 ± 3.62) (p < 0.05). Some inflammatory markers, such as the levels of interleukin-6 and high-sensitivity C-reactive protein (30.29 ± 2.96 vs 17.65 ± 3.22; 8.93 ± 0.99 vs 3.02 ± 0.34), showed a decrease during the intervention, while albumin and prealbumin levels were significantly increased compared with the baseline (30.62 ± 1.65 vs 35.60 ± 1.68; 0.32 ± 0.05 vs 0.44 ± 0.07) (p < 0.05).

CONCLUSION

Combined intervention training can improve the motor ability and quality of life of patients with sarcopenia within a short period of time.

Association Between Changes in Depressive Symptoms and Sarcopenia: Findings From a Nationwide Cohort Study

OBJECTIVES

The aim of this study was to investigate the association between changes in depressive symptoms and sarcopenia by repeated measures of depressive symptoms at a follow-up visit every 2 years.

DESIGN

Cross-sectional design and longitudinal design.

SETTING AND PARTICIPANTS

We conducted a cross-sectional and longitudinal study using data from the China Health and Retirement Longitudinal Study, which is a representative national survey. A total of 12,287 participants were included in Wave 1 (2011-2012) for the cross-sectional analysis, followed by a total of 5285 participants in Wave 2 (2013-2014) and Wave 3 (2015-2016) for the longitudinal analysis based on the cross-sectional analysis.

METHODS

Depressive symptoms were measured by the 10-item Center for the Epidemiological Studies of Depression Short Form. Sarcopenia was defined according to the Asian Sarcopenia Working Group criteria (AWGS 2019). Changes in depressive symptoms in Wave 1 and Wave 2 were used as exposure, and sarcopenia in Wave 3 was used as outcome. Cox proportional hazards regression model was used to test the relationship between changes in depressive symptoms and sarcopenia.

RESULTS

In cross-sectional analysis, depression was significantly associated with sarcopenia (odds ratio, 1.27; 95% CI, 1.10-1.48). In subsequent longitudinal analyses, a total of 174 sarcopenia events occurred, and those with increased depressive symptoms and persistent depressive symptoms were at higher risk for sarcopenia than those without depressive symptoms, with multivariable-adjusted hazard ratios of 1.65 (95% CI, 1.00-2.73) and 1.68 (95% CI, 1.06-2.68), respectively.

CONCLUSIONS AND IMPLICATIONS

People with increased depressive symptoms and persistent depressive symptoms may have a higher risk of developing sarcopenia over time. In the future, more research is needed to confirm the mechanism by which long-term changes in depression contribute to the risk of sarcopenia, and to propose preventive measures accordingly.

Decreased Intracellular to Total Body Water Ratio and Depressive Symptoms in Patients with Maintenance Hemodialysis

Objective

Depression is a common psychiatric disorder and related to poor outcomes in patients undergoing maintenance hemodialysis (MHD). Previous studies have reported some associations between sarcopenia and depressive symptoms. Recently, intracellular water (ICW) and total body water (TBW) have been found to reflect muscle function and muscle mass. ICW/TBW ratio is a marker of sarcopenia that is simple to assess. However, the relationship between ICW/TBW ratio and depression has not been explored in MHD patients.

Methods

In our cross-sectional and multi-center study, 3300 adult MHD patients were included from June 1, 2021, to August 30, 2021. Depressive symptoms were evaluated using the Beck Depression Inventory-II (BDI-II). TBW and ICW were measured by Body Composition Monitor (BCM). Multivariable logistic regression, stratified analyses, and interactive analyses were conducted to assess the relationship between ICW/TBW ratio and depression.

Results

About 16.5% of the 3300 MHD patients were found to have depressive symptoms. The prevalence of depression increased with decreasing quartiles of ICW/TBW ratios, and decreased ICW/TBW ratio was independently associated with depression after adjusting for potential confounders. Patients in Quartile 1 of ICW/TBW ratios were more likely to have depressive symptoms (odds ratio 1.55, 95% confidence interval 1.07-2.22; p=0.002) than those in Quartile 4. History of diabetes and education status had interactive roles in the relationship between depression and ICW/TBW ratios (p < 0.05). The association of ICW/TBW ratios and depression existed in patients of both genders and different education levels, but only in non-diabetic patients.

Conclusion

In MHD patients, the decreased ratio of ICW/TBW was independently related to high depression rates.

Depression and risk of sarcopenia: a national cohort and Mendelian randomization study

Background

Depression and the increased risk of sarcopenia are prevalent among the elderly population. However, the causal associations between these factors remain unclear. To investigate the potential association between depression and the risk of sarcopenia in older adults, this study was performed.

Methods

In the baseline survey, a total of 14,258 individuals aged 40 and above from the China Health and Retirement Longitudinal Study (2015) participated. We initially described the baseline prevalence of the disease. Then, logistic regression and restricted cubic spline (RCS) regression were conducted to assess the relationship between depression and sarcopenia. Subgroup analysis was performed to validate the robustness of the findings. Additionally, we conducted Mendelian randomization analysis using the inverse variance weighting estimator to assess the causal relationship between depression and sarcopenia. Furthermore, we adopted six methods, including MR-Egger, simple median, weighted median, maximum likelihood, robust adjusted profile score (RAPS), and MR Pleiotropy Residual Sum and Outlier (MR-PRESSO), for sensitivity analyses.

Results

Depression patients exhibited higher risks of sarcopenia in all five models adjusting for different covariates (P < 0.05). The RCS analysis demonstrated a linear relationship between depression and sarcopenia (P < 0.05). In the subgroup analysis, increased risk was observed among participants aged 60-70, married or cohabiting individuals, non-smokers, non-drinkers, those with less than 8 h of sleep, BMI below 24, and individuals with hypertension (all P < 0.05). Mendelian randomization results revealed that genetically proxied depression led to a reduction in appendicular skeletal muscle mass (all P < 0.05).

Conclusion

Our study provides observational and causal evidences that depression can lead to sarcopenia. This finding emphasizes the importance of timely identification and management of depression, as well as implementing targeted educational programs as part of comprehensive strategies to prevent sarcopenia.

Mediating role of learned helplessness' components in the association between health literacy/social support and self-management among maintenance haemodialysis patients in Changsha, China: a cross-sectional study

OBJECTIVES

To explore the multiple mediating roles of the learned helplessness's core system in the relationship between health literacy/social support and self-management.

DESIGN

Cross-sectional survey design.

SETTING

Changsha, China.

PARTICIPANTS

239 Chinese maintenance haemodialysis (MHD) patients.

METHODS

Two multiple mediator models were constructed based on the COM-B (Capacity, Opportunity, Motivation - Behaviour) model. A total of 239 Chinese MHD patients participated in a cross-sectional study, which included surveys on the Learned Helplessness Scale for MHD patients, Dialysis Knowledge Questionnaire, Social Support Scale and Self-Management Scale for Haemodialysis. The PROCESS macro in SPSS was used for mediated effects analysis.

RESULTS

Helplessness and internality partially mediated the relationship between health literacy/social support and self-management ((β=-0.212, p<0.01; β=0.240, p<0.01)/(β=-0.331, p<0.001; β=0.376, p<0.001)). The mediation effect size was 0.780 (95% CI (0.373 to 1.218)) in the health literacy model, accounting for 45.29% of the total effect, and 0.286 (95% CI (0.207 to 0.377)) in the social support model, accounting for 57.88% of the total effect. The differences in effect sizes for helplessness and internality in the two models were -0.080 (95% CI (-0.374 to 0.216)) and -0.041 (95% CI (-0.127 to 0.043)), respectively.

CONCLUSION

Health literacy/social support directly affects MHD patients' self-management and indirectly affects it by changing learned helplessness, such as increasing internality while reducing helplessness.

The cross-cultural adaptation and psychometric evaluation of a learned helplessness scale for maintenance hemodialysis patients in China (LHS-MHD-C)

Learned helplessness (LH) is an important concept in nursing. This study aimed to adapt and translate the Arthritis Helplessness Index scale into a Chinese version of an LH scale for maintenance hemodialysis patients in China (LHS-MHD-C), and to validate its psychometric properties. Data collected included LHS-MHD-C, as well as the Hospital Depression Scale (HADS-D), and the Beck Hopelessness Scale (BHS) for assessing LHS-MHD-C's criterion validity (predictive and concurrent, respectively). The expert consultation and the pilot study demonstrated semantic and conceptual equivalence and content validity (except for Item 3, the item content validity ranged from 0.82 to 1, and the scale content validity was 0.95). An exploratory factor analysis (n = 146) eliminated three items and accepted 11 items for the two factors, explaining 63.87% of the total variance. A CFA (n = 218) showed that the two-factors structure was consistent with the LH theory. The LHS-MHD-C can distinguish between maintenance hemodialysis (MHD) patients of different ages, education, working status, monthly income, and MHD duration. The scale had good concurrent validity with the BHS (r = .78, p < 0.01). Using the HADS-D as a criterion, the LHS-MHD-C showed a sensitivity of 86.2% and a specificity of 96.8%. A total score of 36.5 may be the best cut-off value for predicting MHD patients' depression. The scale showed good reliabilities (Cronbach's α value of .759, test-retest reliability of 0.772, and split-half reliability of 0.774). This study found that the LHS-MHD-C is a reliable and valid scale for assessing Chinese MHD patients' helplessness.

Nutritional status and the risk of malnutrition in older adults with chronic kidney disease - implications for low protein intake and nutritional care: A critical review endorsed by ERN-ERA and ESPEN

Increased life expectancy is posing unprecedented challenges to healthcare systems worldwide. These include a sharp increase in the prevalence of chronic kidney disease (CKD) and of impaired nutritional status with malnutrition-protein-energy wasting (PEW) that portends worse clinical outcomes, including reduced survival. In older adults with CKD, a nutritional dilemma occurs when indications from geriatric nutritional guidelines to maintain the protein intake above 1.0 g/kg/day to prevent malnutrition need to be adapted to the indications from nephrology guidelines, to reduce protein intake in order to prevent or slow CKD progression and improve metabolic abnormalities. To address these issues, the European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Renal Nutrition group of the European Renal Association (ERN-ERA) have prepared this conjoint critical review paper, whose objective is to summarize key concepts related to prevention and treatment of both CKD progression and impaired nutritional status using dietary approaches, and to provide guidance on how to define optimal protein and energy intake in older adults with differing severity of CKD. Overall, the authors support careful assessment to identify the most urgent clinical challenge and the consequent treatment priority. The presence of malnutrition-protein-energy wasting (PEW) suggests the need to avoid or postpone protein restriction, particularly in the presence of stable kidney function and considering the patient's preferences and quality of life. CKD progression and advanced CKD stage support prioritization of protein restriction in the presence of a good nutritional status. Individual risk-benefit assessment and appropriate nutritional monitoring should guide the decision-making process. Higher awareness of the challenges of nutritional care in older adult patients with CKD is needed to improve care and outcomes. Research is advocated to support evidence-based recommendations, which we still lack for this increasingly large patient subgroup.

"Alive Day is the Day": A Qualitative Study of Experiences of Learned Helplessness in Maintenance Haemodialysis Patients

Background

Learned helplessness (LH) is a common psychological phenomenon among chronic disease patients. However, LH remains underrecognized in the context of maintenance haemodialysis (MHD) patients. This qualitative study is the first study of this topic to be conducted in a Chinese cultural context, and its purpose is to explore the LH experiences of MHD patients and to highlight their interpretations of LH.

Methods

We employed a qualitative research design. A purposive sampling method was used to recruit participants. The sample size was determined by data saturation. Data were obtained from MHD patients in a blood purification centre located in Hunan Province, China. Data were collected from June to September 2022. The researchers conducted in-depth, semistructured interviews with participants after obtaining informed consent. Texts were transcribed verbatim from the audio recordings of these interviews. Data processing and analysis were based on Giorgi's phenomenological approach.

Results

Twenty-two respondents completed the interviews (aged 29-75 years, including ten females and twelve males). Four themes emerged from the interviews: (1) triggers of helplessness (hope is gone; witnessing renal friends' helplessness; out of control; nothing works); (2) being tied down (limitation; perceived loss; social isolation; giving in); (3) I am just a loser (self-image disorder; low self-concept; negative attitudes; guilt; abandonment); (4) alive day is the day (fatalism; my duty; downwards comparison).

Conclusion

The study reveals that multiple stressors drive MHD patients' LH. These salient phenomena demonstrate the importance of recognizing MHD patients' LH. We suggest that support services should be developed alongside a framework that addresses MHD patients' LH from the beginning of treatment.

The longitudinal association between possible new sarcopenia and the depression trajectory of individuals and their intimate partners

Background

It is currently unknown whether the dynamic nature of depression affects the development of sarcopenia. Herein, this study aims to assess the association between possible new sarcopenia and the depression trajectory of individuals and their intimate partners through a 4-year longitudinal cohort study.

Methods

Our study included 784 pairs of individuals without possible sarcopenia and their spouses from the China Health and Retirement Longitudinal Study (CHARLS) 2011. All individuals and their spouses received three assessments of the Center for Epidemiologic Studies Depression 10-item (CESD-10) scale in 2011, 2013, and 2015. According to the diagnostic algorithm recommended by the Asian Working Group for Sarcopenia (AWGS) 2019, we evaluated the incidence of possible sarcopenia in individuals in 2015. Latent class analysis (LCA) was used to identify a longitudinal depression trajectory of individuals and their spouses during a 4-year follow-up. Subsequently, we assessed the relationship between possible sarcopenia and depression trajectory using three generalized additive models.

Results

In 2015, 24.87% (195/784) of individuals were diagnosed with possible sarcopenia. LCA identified five depression trajectories: a persistently high risk of depression in individuals and their spouses (reference; class 1 = 34 [4.3%]); a persistently low risk of depression in individuals and their spouses (class 2 = 526 [67.1%]); a high risk of depression in individuals and a low risk of depression in spouses (class 3 = 46 [5.9%]); a low risk of depression in individuals and a high risk of depression in spouses (class 4 = 116 [14.8%]); and a reduced risk of depression in individuals and their spouses (class 5 = 62 [7.9%]). The highest incidence of possible sarcopenia was shown in class 1, followed by classes 3 and 5. Classes 2 (adjusted relative risk (RR) = 0.44, 95% confidence interval (CI): 0.20-0.97) and 4 (adjusted RR = 0.40, 95%CI: 0.17-0.96) had a significantly lower incidence of possible sarcopenia than class 1. Subgroup analysis demonstrated that the incidence of possible sarcopenia in class 4 was obviously higher in women (38.89%) than in men (18.4%).

Conclusions

Our study indicates a persistently high risk of depression in individuals to develop possible sarcopenia. In addition, a persistently high risk of depression in intimate partners potentially increases the risk of possible new sarcopenia, especially in female individuals who are at low risk of depression.

Daytime napping, comorbidity profiles, and the risk of sarcopenia in older individuals

Appropriate daytime napping is associated with the decreased risk of cerebro-cardiovascular diseases, but whether daytime napping affects sarcopenia remains to be explored. Our study plans to examine the associations between sarcopenia with daytime napping and comorbidity. The study population came from the China Health and Retirement Longitudinal Study 2011-2015. Latent class analysis (LCA) was used to identify comorbidity profiles based on 14 doctor-diagnosed chronic diseases. Subsequently, smooth function and restricted cubic spline with three binomial regression models determined the associations between sarcopenia with daytime napping and comorbidity profiles. About 18.7% (2,894) and 5.4% (832) of 15,404 individuals were diagnosed with sarcopenia and severe sarcopenia. LCA delineated four classes as the best fit as follows: dominant heart diseases or risks (class 1, N = 2,203), dominant chronic lung diseases (class 2, N = 740), minimal or least diseases (class 3, N = 10,612, reference), and dominant digestive diseases and rheumatism (class 4, N = 1849). Compared with the reference group (class 3), the multivariate-adjusted ORs (95% CIs) of sarcopenia in model 3 were 0.72 (0.60-0.88) for class 1, 1.17 (0.92-1.51) for class 2, and 0.92 (0.77-1.09) for class 4. Smooth function and restricted cubic spline suggested that individuals who napped about 60 min seemingly had the lowest risk of sarcopenia. Individuals who napped for 1-59 min (adjusted OR = 0.80, 95% CI: 0.68-0.94) and 60-119 min (adjusted OR = 0.83, 95% CI: 0.72-0.95) had the significantly lower risk of sarcopenia but not severe sarcopenia than those who did not nap. Insufficient and excessive daytime napping might be associated with the increased risk of sarcopenia, especially in individuals with a dominant chronic lung disease profile.

Trust in the attending rheumatologist, health-related hope, and medication adherence among Japanese systemic lupus erythematosus patients

OBJECTIVE

Poor medication adherence among patients with systemic lupus erythematosus (SLE) is a critical problem associated with adverse outcomes. This study examined the relationship between trust in one's physician and goal-oriented thinking, hope, and medication adherence among Japanese patients with SLE who were ethnically matched to their physicians.

METHODS

This cross-sectional study was conducted in the rheumatology outpatient clinics at five academic centres. Patients with SLE who were prescribed oral medications were included. The main exposure was trust in one's physician measured via the 5-item Japanese version of the Wake Forest Physician Trust Scale and the 18-item Health-related Hope Scale, with each score ranging from 0 to 100 points. Medication adherence was measured using the 12-item Medication Adherence Scale with scores ranging from 5 to 60 points. A general linear model was created after adjusting for demographics, socioeconomic status, disease activity, disease duration, basic health literacy, depression, medication variables, experiencing adverse effects, and concerns regarding lupus medications.

RESULTS

Altogether, 373 patients with SLE were included. The mean age of the patients was 46.4 years; among them, 329 (88.2%) were women. Both trust in one's physician (per 10-point increase: 0.88, 95% confidence interval [95% CI]: 0.53-1.24) and the Health-related Hope score (per 10-point increase: 0.64, 95% CI: 0.33-0.95) were associated with better medication adherence.

CONCLUSION

This study demonstrated that patients' health-related hope and trust in their rheumatologist were both associated with better medication adherence in SLE.

The association between sense of coherence and quality of life: a cross-sectional study in a sample of patients on hemodialysis

Background

Patients on hemodialysis universally experience detriments in their general quality of life (QOL). Sense of coherence (SOC) is a long-standing factor that affects QOL. Nevertheless, the association between SOC and QOL in patients on hemodialysis was seldom investigated. Our research aims to study this association in a sample of Lebanese adult patients on hemodialysis.

Methods

In this cross-sectional study, SOC was measured using the short version of the “Orientation of Life" scale (SOC-13). QOL was assessed using the Kidney Disease Quality of Life- Short Form (KDQOL-SF). The association between SOC and QOL and its submodalities was first explored using Pearson Correlation and multivariate linear regression analyses, controlling for sociodemographic variables and medical variables.

Results

157 patients on hemodialysis (mean(SD) age: 62.1(13.81) years; 58.6% males) were included. Mean QOL score was 51.65 and that of SOC was 48.06. SOC was strongly corrected with the total QOL (r = 0.832; p value < 0.001), as well as its physical functioning (r = 0.767; p value < 0.001), emotional functioning (r = 0.757; p value < 0.001), cognitive functioning (r = 0.740; p value < 0.001), and social functioning (r = 0.773; p value < 0.001) submodailties. SOC was moderately correlated with professional functioning submodality of QOL (r = 0.618; p value < 0.001), but not correlated with the satisfaction with the quality of care (r = 0.052; p = 0.520). Within the regression models accounting for sociodemographic and medical variables, SOC was significantly associated with the total QOL (unstandardized B = 0.803; 95% CI 0.714, 0.893), physical functioning (unstandardized B = 0.761; standardized B = 0.763; 95% CI 0.661, 0.861), emotional functioning (unstandardized B = 1.205; standardized B = 0.757; 95% CI 1.037, 1.372), professional functioning (unstandardized B = 1.142; standardized B = 0.498; 95% CI 0.843, 1.442), cognitive functioning (unstandardized B = 1.239; standardized B = 0.739; 95% CI 1.058, 1.420), and social functioning (unstandardized B = 0.912; standardized B = 0.768; 95% CI 0.790, 1.034).

Conclusions

In a sample of adult patients on hemodialysis, SOC was positively significantly associated with QOL and its submodalities, expect the satisfaction with the quality of care. The confirmation of the general hypothesis that relates the SOC with the QOL encourages more salutogenic research among this patient population.

Frailty as an Independent Risk Factor for Depression in Patients With End-Stage Renal Disease: A Cross-Sectional Study

Background

Depression confers substantial disease burden globally, especially among those with chronic kidney disease (CKD). The presence of depression significantly impairs one's quality of life. Risk factors for depression in patients with CKD remain under-appreciated, and whether frailty, a geriatric phenotype, constitutes a risk factor for depression in this population is unknown.

Methods

We prospectively enrolled patients with end-stage renal disease (ESRD) undergoing hemodialysis for >3 months from National Taiwan University Hospital Yunlin Branch between 2019 and 2021. Clinical, physical, functional, and performance parameters were recorded, followed by frailty/sarcopenia assessment. Depression was screened for using the Geriatric Depression Scale. We analyzed the independent relationship between frailty and depression in these patients, using multiple regression analyses.

Results

Totally 151 patients with ESRD were enrolled (mean 61.1 years, 66.9% male), among whom 16.6% had screening-identified depression. ESRD participants with depression did not differ from those without regarding most parameters except serum creatinine, functional indices, and sarcopenia/frailty status. We found that having greater frail severities was independently associated with a higher probability of depression; having FRAIL- (odds ratio [OR] 5.418) and SOF-based (OR 2.858) frailty independently correlated with a higher depression probability. A linear relation exists between a greater frail severity and the probability of depression. Using a more relaxed criterion for detecting depression, higher SOF scores remained significantly associated with an increased depression risk.

Conclusions

In patients with CKD, frailty independently correlated with a higher probability of having depression. Strategies aiming to attenuate frailty may be able to benefit those with depression simultaneously in this population.

Mediating Effects of Malnutrition on the Relationship between Depressive Symptoms Clusters and Muscle Function Rather than Muscle Mass in Older Hemodialysis Patients

OBJECTIVES

The purpose of this study was to investigate the association and mediation pathways among muscle mass, muscle function (muscle strength and physical performance), and malnutrition with depressive symptoms clusters in the older hemodialysis patients.

DESIGN

A multi-center cross-sectional study.

SETTING AND PARTICIPANTS

A total of 499 patients aged ≥ 60 on hemodialysis from seven facilities in Shanghai of China from 2020 to 2021.

MEASUREMENTS

Muscle mass was assessed by skeletal muscle index(SMI). Muscle strength was measured by handgrip strength, and physical performance was measured via gait speed and Timed Up and Go Test (TUGT). Nutritional status was assessed by Malnutrition Inflammation Score (MIS). Depressive symptoms were evaluated by the Patient Health Questionnaire-9 (PHQ-9). Logistic regression and mediation analyses fully adjusted for all potential confounding factors.

RESULTS

Among 499 participants (312 men, mean age 69.2±6.6 years), 108 (21.6%) had depressive symptoms. The muscle strength, physical performance and malnutrition were associated with depressive symptoms. Furthermore, malnutrition significantly mediated the association of muscle function with total, cognitive-affective symptoms. The association of the muscle function with somatic symptoms were mediated by the nutritional status. The mediated proportions of malnutrition in the relationship between physical performance and depressive symptoms clusters were stronger in somatic symptoms than in cognitive-affective symptoms.

CONCLUSIONS

Our findings suggest that muscle function rather than muscle mass may contribute substantially to the development of depressive symptoms clusters in the hemodialysis via malnutrition. The malnutrition mediated stronger in the association of muscle function with somatic symptoms. These findings may help guide clinicians to better diagnose and manage depression in the context of concomitant muscle function and malnutrition.

Learned Helplessness in Renal Dialysis Patients: Concept Analysis with an Evolutionary Approach

BACKGROUND

Learned helplessness is an early psychological concept, but in the field of nursing, the concept of learned helplessness in renal dialysis patients and its unique challenges are not well understood.

OBJECTIVE

This article provides a conceptual analysis of learned helplessness in renal dialysis patients to increase knowledge of this psychological phenomenon in the setting of renal nursing.

DESIGN

Rodgers' evolutionary concept analysis.

METHODS

The literature published in five databases (PubMed, CINAHL, Embase, PsycINFO, CNKI) was searched using specific terms. In the first stage, search terms and strategies were used to narrow the relevant articles. In the second stage, the data were extracted from the included articles. In the third stage, the data were analyzed using thematic analysis, and the results were presented in the form of attributes, antecedents, consequences, surrogate terms, and related terms. We found additional instruments and interventions and presented a model case to emphasize the practicality of the concept. In the fourth phase, experts contributed to the discussion and interpretation of the findings.

RESULTS

A total of 22 articles were included. Four attributes of learned helplessness in renal dialysis patients were identified: low self-concept, perceived loss, negative cognitive set, and abandonment of action. The antecedents were sociodemographic characteristics, disease and treatment, and psychological factors. Consequences were separated into four themes: psychological problems, physiological problems, quality of life, and health-related behavior. Surrogate terms are hopelessness and powerlessness, and the related term is depression.

CONCLUSION

The process of conceptual analysis in this study provides a means of identifying awareness gaps and practice challenges of learned helplessness in renal dialysis patients and other concepts. The findings can be used to guide the design of tools and interventions to expand the use of learned helplessness theory in nursing.

Associations between Depression, Nutritional Status and Mediterranean Diet in Dalmatian Kidney Transplant Recipients

Depression has been addressed as a predictor of worse outcomes in kidney transplant recipients (KTRs). Nutritional status plays a great role in treatment of this population. The Mediterranean diet (MeDi) has been associated with lower levels of depressive symptoms. The aim of this cross-sectional study was to determine the rate of depression and its correlations to nutritional status and dietary habits according to the MeDi in Dalmatian KTRs. We included 115 KTRs, and data about body composition and anthropometric, laboratory and clinical parameters were obtained for each study participant. The Beck Depression Inventory-II (BDI-II) questionnaire was used to assess depressive symptoms and the Mediterranean Diet Serving Score (MDSS) was used to assess adherence to the MeDi. We found the presence of depressive symptoms in 21.73% of the Dalmatian KTRs. BDI-II score was reciprocally associated with fat mass, trunk visceral fat, anthropometric parameters of obesity, triglyceride levels and olive oil consumption. Inverse associations were found between BDI-II score and skeletal muscle mass, handgrip strength, MCV, hemoglobin levels and consumption of fish and white meat, as suggested by the MeDi. Our results showed the interconnections between nutritional status, dietary habits and depression in Dalmatian KTRs.

Depression Impairs Level of Functioning in Chronic Kidney Disease Inpatients: A Case-Control Study

Objectives To evaluate the difference in demographics and clinical correlates during hospitalization for chronic kidney disease (CKD) between patients with depression and those without depression, and its impact on the severity of illness and in-hospital mortality. Methods We conducted a case-control study and included 2,296 adult inpatients (age ≥18 years) with a primary discharge diagnosis of CKD using the nationwide inpatient sample (NIS). We used propensity score matching to extract the cases i.e., CKD inpatients with depression (N = 1,264) and the controls i.e. CKD inpatients without depression (N = 1,032). The matching was done based on demographic characteristics of age at admission, sex, race, and median household income. Our outcomes of interest are the severity of illness and all-cause in-hospital mortality. All patient refined drg (APR-DRG) are allocated using health information systems software by the NIS and the severity of illness within each base APR-DRG was classified into minor, moderate, or major loss of body functions. Binomial logistic regression analysis was conducted to find the odds ratio (OR) of association for major loss of function in CKD inpatients with depression, and this model was adjusted for potential confounders of congestive heart failure (CHF), coronary artery disease (CAD), diabetes, hypertension, obesity, and tobacco abuse, and utilization of hemodialysis. Results A higher proportion of CKD inpatients with depression had a statistically significant higher prevalence of major loss of function (49.8% vs. 40.3% in non-depressed). There was a statistically significant difference with higher utilization of hemodialysis in CKD inpatients with depression (76.2% vs. 70.7% in non-depressed). The all-cause in-hospital mortality rate was lower in CKD inpatients with depression (2.1% vs. 3.5% in non-depressed). After controlling the logistic regression model for potential comorbidities and utilization of hemodialysis, depression was associated with increased odds (OR 1.46; 95% CI 1.227 - 1.734) for major loss of function versus in non-depressed CKD inpatients Conclusion Comorbid depression increases the likelihood of major loss of functioning in CKD inpatients by 46%. Treating depression can allow patients to better cope emotionally and physically with CKD and other comorbidities and significantly improve the patient's quality of life (QoL) and health outcome.

Comorbid Depressive Symptoms, Visual Impairment, and Sarcopenia among Middle-Aged and Older Women: Findings from the West China Health and Aging Trend study

Previous reports have described close relationships between sarcopenia and either visual impairment or depression, but there have been few analyses investigating the association between sarcopenia and the coexistence of both visual impairment and depression. Herein, we sought to explore the associations between sarcopenia and comorbid depressive symptoms and visual impairment among older females. A cross-sectional analysis of females between the ages of 50 and 95 (n = 2454) from the West China Health and Aging Trend (WCHAT) study was conducted. Patient muscle mass was assessed via a bioimpedance-based approach using an InBody 770 device, while muscle strength was estimated based on handgrip strength as quantified with a digital grip strength dynamometer. Depressive systems were evaluated with the 15-item Geriatric Depression Scale (GDS-15), and a questionnaire was employed to evaluate patient visual functionality. Associations between sarcopenia and comorbid depressive status and visual impairment were explored through logistic regression analyses. Comorbid depressive symptoms and visual impairment were observed in 6.2% of the women included in this study, while 18.9% suffered from sarcopenia. Following adjustment for covariates, relative to normal controls, study subjects with only depression (OR=1.45, 95%CI=1.04-2.02), only visual impairment (OR=1.69, 95%CI=1.27-2.26), or comorbid depression and visual impairment (OR=1.76, 95% CI=1.16-2.67) exhibited a higher risk of sarcopenia. These results suggest that comorbid depression and visual impairment are linked to the prevalence of sarcopenia in older Chinese women. As such, further efforts to screen older women for these two comorbid conditions may thus be necessary.

Association between Depressive Symptoms and Risk of Sarcopenia in Taiwanese Older Adults

OBJECTIVES

Symptoms of depression and high risk of sarcopenia are common among the older population; however, the associations between these remain unclear. Thus, the present study identified whether depressive symptoms are associated with older adults' sarcopenia risks.

PARTICIPANTS

This nationally representative study in Taiwan investigated the older adult population ( ≥ 65 years) using a telephone survey conducted between 2019 and 2020.

DESIGN

Self-reported data obtained included depressive symptoms (5-item from Center for Epidemiological Studies-Depression scale), sarcopenia risks (SARC-F questionnaire), and individual characteristics. The generalized additive models were used to examine the nonlinear associations between depressive symptoms and the risk of sarcopenia.

RESULTS

A total of 1,068 older Taiwanese adults (72.15 ± 5.71 years; 52.7% women) participated in the survey. In the unadjusted model, the results showed a significant nonlinear association between high scores on the CES-D and sarcopenia scores (p < .001). Even after adjusting for covariates (sex, age, residential areas, education, marital status, working status, living status, smoking, drinking, and BMI), it still showed a significant non-linear association (p < .001).

CONCLUSION

The results indicated that depressive symptoms were nonlinearly related to older adults' sarcopenia risks. Interventions or programs aiming to alleviate depression can be an effective strategy to prevent sarcopenia in the older adult population.
