The Relationship between Quality of Life and Cognitive Functions, Anxiety and Depression among Hospitalized Elderly Patients

Social support in maintaining mental health and quality of life among community-dwelling older people with functional limitations in Malaysia: a population-based cross-sectional study

OBJECTIVE

This study aimed to examine the mediation role of perceived social support in the relationship between functional limitations, depressive symptoms and quality of life among older people in Malaysia.

SETTING

The Malaysian National Health Morbidity Survey 2018: Elderly Health was a cross-sectional health community survey among adults aged 50 and above.

PARTICIPANTS

3977 community-dwelling older Malaysians aged 60 and above.

OUTCOME MEASURES

Functional limitations were defined as personal activities of daily living (PADL) and instrumental activities of daily living (IADL), tested in separate paths in all analyses. PADL was measured using the Barthel Index, while IADL was measured using the Lawton and Brody scale. Perceived social support, depressive symptoms and quality of life were measured using the Duke Social Support Index, Geriatric Depression Scale-14 and Control, Autonomy, Self-Realisation and Pleasure-19 tools. We used mediation analysis through structural equation modelling to explore the role of perceived social support.

RESULTS

Perceived social support mediated the relationship between PADL and IADL with depressive symptoms, with the indirect effects at -0.079 and -0.103, respectively (p<0.001). Similarly, perceived social support mediated the relationship between PADL and IADL with quality of life, with the indirect effects at 0.238 and 0.301, respectively (p<0.001). We performed serial multiple mediation analysis and found that perceived social support and depressive symptoms mediated the path between PADL and IADL with quality of life, with the indirect effects at 0.598 and 0.747, respectively (p<0.001). The relationship between functional limitations and all outcomes remained significant in all mediation analyses.

CONCLUSION

The present study provides evidence that perceived social support relieves the influence of functional limitations on depressive symptoms and declining quality of life among older people. Therefore, it is imperative to establish a social support system to improve the overall well-being of older people.

Exploring the Association Between Loneliness, Subjective Cognitive Decline, and Quality of Life Among Older Thai Adults: A Convergent Parallel Mixed-Method Study

Examining the rising prevalence of subjective cognitive decline as an early indicator of dementia in adults, this study investigates its complex interaction with loneliness and quality of life in individuals with preclinical dementia. Using a convergent parallel mixed-method approach, we employed Structural Equation Modeling on a cohort of 149 older adults. Qualitative insights were derived from focused group discussions and in-depth semi-structured interviews with a cohort of 23 older adults. Loneliness emerges as a pivotal contributor, exerting a discernible partial indirect effect on quality of life through subjective cognitive decline (indirect effect = -0.145, p = .006). Noteworthy differentials surfaced, with the impact of subjective cognitive decline on quality of life heightened in those with chronic diseases (△χ2 = 6.139, p = .013). Loneliness, wielding a palpable impact, intricately interlaces with quality of life, the nexus of which is intricately mediated by subjective cognitive decline.

Longitudinal study of changes observed in quality of life, psychological state cognition and pulmonary and functional capacity after COVID-19 infection: A six- to seven-month prospective cohort

AIMS

To investigate the health-related quality of life (HRQoL), symptoms, psychological and cognitive state and pulmonary and physical function of nonhospitalised COVID-19 patients at long-term, and to identify factors to predict a poor HRQoL in this follow-up.

BACKGROUND

Studies have focused on persistent symptoms of hospitalised COVID-19 patients in the medium term. Thus, long-term studies of nonhospitalised patients are urgently required.

DESIGN

A longitudinal cohort study.

METHODS

In 102 nonhospitalised COVID-19 patients, we collected symptoms at 3 months (baseline) and at 6-7 months (follow-up) from diagnosis (dyspnoea, fatigue/muscle weakness and chest/joint pain), HRQoL, psychological state, cognitive function, pulmonary and physical function. This study adhered to the STROBE statement.

RESULTS

HRQoL was impaired in almost 60% of the sample and remained impaired 6-7 months. At 3 months, more than 60% had impaired physical function (fatigue/muscle weakness and reduced leg and inspiratory muscle strength). About 40%-56% of the sample showed an altered psychological state (post-traumatic stress disorder (PTSD), anxiety/depression), cognitive function impairment and dyspnoea. At 6-7-months, only a slight improvement in dyspnoea and physical and cognitive function was observed, with a very high proportion of the sample (29%-55%) remained impaired. Impaired HRQoL at 6-7 months was predicted with 82.4% accuracy (86.7% sensitivity and 83.3% specificity) by the presence at 3 months of muscle fatigue/muscle weakness (OR = 5.7 (1.8-18.1)), PTSD (OR = 6.0 (1.7-20.7)) and impaired HRQoL (OR = 11.7 (3.7-36.8)).

CONCLUSION

A high proportion of nonhospitalised patients with COVID-19 experience an impaired HRQoL, cognitive and psychological function at long-term. HRQoL, PTSD and dyspnoea at 3 months can identify the majority of patients with COVID-19 who will have impaired quality of life at long-term.

RELEVANCE TO CLINICAL PRACTICE

Treatments aimed at improving psychological state and reducing the fatigue/muscle weakness of post-COVID-19 patients could be necessary to prevent the patients' HRQoL from being impaired at 6-7 months after their reported recovery.

Determinants of semantic and episodic memory decline among older adults in Ghana: Evidence from the WHO study on global AGEing and adult health Ghana wave 2

Objective

Determined factors associated with semantic (SM) and episodic memory (EM) among older adults aged 50 years and older in Ghana.

Methods

Data from WHO Study on Global AGEing and Adult Health (SAGE) Ghana Wave 2 was used for this study. Semantic memory (SM) and Episodic memory (EM) were the main study outcomes separately. The study employed Nested Ordinary Least Square regression analysis by sequentially adding 6 blocks of variables and comparison tests between the nested models.

Results

The study involved 3575 adult Ghanaians aged 50 years and older with a mean ± standard deviation of 62.6 ± 18.4 years. The overall mean ± SD of EM and SM were 5.86 ± 2.51 and 11.69 ± 8.59 respectively. Overall, analysis from block 6 showed a significant variation in SM by approximately 16.9%(ΔR2 = 1.17%) where increasing age, never married (β = -1.55; 95% CI = -2.41-0.69), being resident in Greater Accra (regional disparity) (β = -3.45; 95% CI = -4.73-2.20), underweight (β = -0.81;95% CI = -1.34-0.27), and moderate self-rated health (SRH) (β = -0.98; 95% CI = -1.52-0.45) significantly decreased SM. Similarly, increasing age, separated/divorced (β = -0.22; 95% CI = -0.35-0.87), being resident in Greater Accra (β = -0.53; 95% CI = -0.80-0.26), and moderate SRH (β = -0.20; 95% CI = -0.36--0.04) significantly decrease EM with an overall significant variation of approximately 22.9%(ΔR2 = 2.7%).

Conclusions

Increasing age, sex, marital status, regional disparity, and poor SRH significantly decreased both Semantic memory and Episodic memory. Higher educational attainment and life satisfaction significantly influenced SM and EM. These provide pointers to important socio-demographic determinants of SM and EM with implications for the implementation of the Ghana national ageing policy 2010, 'ageing with security and dignity', and as a key consideration for healthy ageing towards 2030.

The Relationship Between Quality of Life and Depressive Symptoms Among Jordanian Community-Dwelling Older Adults

OBJECTIVE

The current study aimed to examine the relationship between depressive symptoms and quality of life among Jordanian community-dwelling older adults.

METHODS

A cross-sectional, descriptive correlational design was used. A convenience sample (N = 602) was selected to recruit the participants in the Amman governorate during the period from August to November 2021.

RESULTS

Findings demonstrated that the mean (SD) age of older adults was 67.5 (7.0) years and 51.5% of participants were females. Also, 54.1% of the participants experienced moderate to severe depressive symptoms with a total mean (SD) score was 8.57 on a scale of 0 to 15, while the mean (SD) for the quality of life scale was 12.12 (3.85) on a scale of 4 to 20. Significant differences existed in quality of life and depressive symptoms based on marital status (p < .001), educational level (p < .001), working status (p < .01), income (p < .001), and chronic disease (p < .01). Quality of life and its domains were negatively associated with depressive symptoms (B= - 0.596, p < .001). Also, marital status, working, educational level, income, and chronic disease were associated with depressive symptoms.

CONCLUSION

Strategies to improve quality of life should be promoted to minimize depressive symptoms among older adults and consider significant demographic factors.

Psychological resilience and quality of life among middle-aged and older adults hospitalized with chronic diseases: multiple mediating effects through sleep quality and depression

BACKGROUND

The present study is intended to examine the multiple mediating roles of sleep quality and depression in the relationship between psychological resilience and quality of life in middle-aged and older adults hospitalized with chronic diseases.

METHODS

From October 2, 2021, to February 27, 2022, a questionnaire survey was conducted using a multistage stratified sampling method among 339 middle-aged and older adults (45 years and over) hospitalized with chronic diseases. These participants were recruited from a hospital in Zhejiang Province, China. The questionnaire included the Aged Cumulative Disease Rating Scale, the Psychological Resilience Scale, the Pittsburgh Sleep Quality Index Scale, the Depression Scale, and the Quality-of-Life Scale. A descriptive analysis was performed to characterize the sample. Linear regression was utilized to evaluate the relationship between psychological resilience and quality of life. Amos 24.0 was used to analyze the multiple mediated effects of sleep quality and depression.

RESULTS

Psychological resilience exerted a remarkable direct effect on the quality of life in middle-aged and older adults hospitalized with chronic diseases (β = 0.239, 95% CI = 0.125-0.354), which represented 52.98% of the total effect. Through three significantly mediated pathways indirectly affect the quality of life: (1) through the sleep quality pathway (β = 0.115, 95% CI = 0.056-0.201), which represented 25.39% of the total effect; (2) through the depression pathway (β = 0. 060, 95% CI = 0.023-0.114), which represented 13.24% of the total effect; and (3) through both the sleep quality and depression pathway (β = 0. 038, 95% CI = 0.019-0.074), which represented 8.39% of the total effect. The total mediating effect was 47.02%.

CONCLUSIONS

Sleep quality and depression mediate the relationship between psychological resilience and quality of life in middle-aged and older adults hospitalized with chronic diseases. Therefore, healthcare professionals and stakeholders should be concerned about the sleep status and mental health of middle-aged and older adults hospitalized with chronic diseases, strengthen their attention to psychological resilience, and provide interventions and treatment measures for hospitalized patients who have sleep problems and depressive tendencies.

Live bedside music for hospitalized older adults: A qualitative descriptive interview study

INTRODUCTION

Hospitalization may have a major impact on older patients as it is often a period of psychosocial vulnerability. Music is one of the most described art forms used in healthcare. Applied in clinical settings, it can affect a patients' emotional and psychosocial well-being. Incorporating a wider perspective of health promotion that aims to advance not only physical health, but a patients' overall well-being, is part of a person-centred approach to care. We developed an innovative participatory music practice in which professional musicians and music therapists visited patients at their bedside for 10-15 min in a Dutch and Austrian hospital. This qualitative study explores the added value of live bedside music practice for older hospitalized patients in Austria and the Netherlands.

METHODS

Semi-structured interviews were conducted between October 2020 and February 2022 with 23 hospitalized patients aged ≥60 years. Due to the COVID-19 pandemic, the music sessions in Austria were facilitated by establishing a live connection between musicians and patients using a tablet. Data were transcribed verbatim and performed qualitative content analysis following the steps of thematic analysis. The COnsolidated criteria for REporting Qualitative research (COREQ) checklist was applied to report data collection, analysis and results.

RESULTS

Four themes emerged from the data analysis. Participants described the perceived influences of live bedside music in terms of (1) emotional release, (2) positive distraction, (3) alterations in contact and (4) shared humanity. Overall, participants positively valued the live bedside music practice and expressed a desire for its continuation.

CONCLUSION

This study explores the experiences and the added value of live bedside music for older hospitalized patients. By facilitating distraction and emotional release and enhancing nurse-patient interactions, live bedside music can significantly improve hospital experiences for older patients. Results reveal that live bedside music provides a positive patient experience and can be part of integrative and holistic care for hospitalized older patients. Live bedside music can attend to the emotional needs of older patients which are often under addressed in clinical settings but are crucial for enhancing their well-being.

Hospitalized Women Have Anxiety and Worse Mental Health Scores than Men

This study aimed to assess the levels of anxiety, depression, and quality of life in hospitalized men and women using the Hospital Anxiety and Depression Scale (HADS), Beck's Anxiety Inventory (BAI), and Short Form-36 Health Survey Questionnaire (SF-36). 60 patients of both sexes were recruited from at the outpatient department of the Hospital Universitário de Vassouras (HUV). The HADS-Anxiety (HADS-A) and BAI questionnaires were used to assess anxiety; the HADS-Depression (HADS-D) questionnaire to assess levels of depression, and the SF-36 to assess the quality of life. The results indicated that hospitalized women had higher levels of anxiety when compared to men. No difference was observed in the levels of depression between men and women. Regarding quality of life, women showed more deterioration in general and mental health compared to men. Thus, the findings suggest that hospitalized women have higher levels of anxiety when compared to men and that this increase can lead to worse general and mental health. Professionals should be aware of possible psychological changes in hospitalized women as they can affect the overall quality of life.

Cognitive Impairment after Post-Acute COVID-19 Infection: A Systematic Review of the Literature

The present study aims to provide a critical overview of the literature on the relationships between post-acute COVID-19 infection and cognitive impairment, highlighting the limitations and confounding factors. A systematic search of articles published from 1 January 2020 to 1 July 2022 was performed in PubMed/Medline. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Only studies using validated instruments for the assessment of cognitive impairment were included. Out of 5515 screened records, 72 studies met the inclusion criteria. The available evidence revealed the presence of impairment in executive functions, speed of processing, attention and memory in subjects recovered from COVID-19. However, several limitations of the literature reviewed should be highlighted: most studies were performed on small samples, not stratified by severity of disease and age, used as a cross-sectional or a short-term longitudinal design and provided a limited assessment of the different cognitive domains. Few studies investigated the neurobiological correlates of cognitive deficits in individuals recovered from COVID-19. Further studies with an adequate methodological design are needed for an in-depth characterization of cognitive impairment in individuals recovered from COVID-19.

Evaluation of the Reliability and Validity of the Alzheimer's Disease-Related Quality of Life Instrument among Older Adults with Cognitive Impairment in Mainland China

The purpose of this study is to examine the reliability and validity of the ADRQL instrument among older adults with cognitive impairment in mainland China. Three hundred older adults with cognitive impairment and their primary family caregivers from Wuhan participated in structured interviews. Cronbach's α and Kuder-Richardson Formula 20 were used to examine internal consistency reliability. Confirmatory factor analysis, Heterotrait-Monotrait ratios, and ordinary least square regression were used to assess the factorial validity, discriminant validity, and criterion validity. The ADRQL had acceptable reliability and validity, which can be used to assess overall quality of life for this population.

Predictors for quality of life among older adults with depressive disorders: A prospective 3-month follow-up cohort study

PURPOSE

The study aimed to investigate the predictive factors for quality of life among subjects with late-life depression.

DESIGN AND METHODS

Data including depressive symptoms assessed by the Hamilton Rating Scale of Depression (HAMD), geriatric depression scale (GDS), perceived stress scale (PSS), multidimensional scale for perceived social support, and the EQ-5D scale were collected at baseline and at 3-month follow-up from 264 participants.

FINDINGS

After controlling for covariates, time, GDS, PSS, HAMD, and living alone were confirmed predictors for change of EQ-5D scores.

PRACTICE IMPLICATIONS

Perceived stress is important, and intervention to reduce stress especially in early treatment of depressive disorder should be encouraged.

Correlations between Persistent Olfactory and Semantic Memory Disorders after SARS-CoV-2 Infection

Background: One of the main symptoms of COVID-19 is hyposmia or even anosmia. Olfactory identification is most often affected. In addition, some cognitive disorders tend to appear following the infection, particularly regarding executive functions, attention, and memory. Olfaction, and especially olfactory identification, is related to semantic memory which manages general knowledge about the world. The main objective of this study was to determine whether semantic memory is impaired in case of persistent post COVID-19 olfactory disorders. Methods: 84 patients (average age of 42.8 ± 13.6 years) with post COVID-19 olfactory loss were included after consulting to the ENT department. The clinical evaluation was carried out with the Pyramid and Palm Tree Test, the word-retrieval task from the Grémots, the Sniffin’ Sticks Test and the Computerised Olfactory Test for the Diagnosis of Alzheimer’s Disease. Results: Semantic memory was impaired in 20% (n = 17) of patients, especially in the 19–39 age-group. The olfactory threshold was only significantly correlated with the semantic memory scores. Conclusions: Similar to all cognitive disorders, semantic disorders can have a negative impact on quality of life if left untreated. It is essential to carry out specific assessments of post COVID-19 patients to accurately determine their disorders and to put in place the best possible rehabilitation, such as speech and language therapy, to avoid quality-of-life impairment.

Changes in cognitive functioning after COVID-19: A systematic review and meta-analysis

Introduction

We conducted a systematic review and meta‐analysis of the cognitive effects of coronavirus disease 2019 (COVID‐19) in adults with no prior history of cognitive impairment.

Methods

Searches in Medline/Web of Science/Embase from January 1, 2020, to December 13, 2021, were performed following Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines.  A meta‐analysis of the Montreal Cognitive Assessment (MoCA) total score comparing recovered COVID‐19 and healthy controls was performed.

Results

Oof 6202 articles, 27 studies with 2049 individuals were included (mean age = 56.05 years, evaluation time ranged from the acute phase to 7 months post‐infection). Impairment in executive functions, attention, and memory were found in post‐COVID‐19 patients.  The meta‐analysis was performed with a subgroup of 290 individuals and showed a difference in MoCA score between post‐COVID‐19 patients versus controls (mean difference = −0.94, 95% confidence interval [CI] −1.59, −0.29; P = .0049).

Discussion

Patients recovered from COVID‐19 have lower general cognition compared to healthy controls up to 7 months post‐infection.

Possibility for Prevention of Type 2 Diabetes Mellitus and Dementia Using Three Kinds of Brown Rice Blends after High-Pressure Treatment

As it has been reported that type 2 diabetes mellitus increases the risk of Alzheimer’s disease, we investigated how to prevent type 2 diabetes and dementia using biofunctional boiled rice. We adopted unpolished super-hard rice (SHBR) for diabetes and wax-free unpolished black rice (WFBBR) for dementia and blended those with ordinary non-polished rice (KBR) (blending ratio 4:4:2), adding 2.5% waxy black rice bran (WBB) and 0.3% rice oil after high-pressure treatment (HPT) (WFBSK) to improve its palatability. This boiled rice is rich in dietary fiber, anthocyanin, free ferulic acid and β-secretase inhibitory activity. A randomized, parallel-group comparison study was conducted for 12 weeks with 24 subjects, using Cognitrax to evaluate their cognitive function primarily. Furthermore, as the secondary purpose, we performed a single-dose test for postprandial blood glucose and insulin secretion at the end of the human intervention test. After 12 weeks, consumers of the WFBSK rice exhibited significant improvement in language memory by cognitive test battery compared with those who consumed the control white rice (p < 0.05). Moreover, subjects who consumed the WFBSK rice had lower insulin secretion levels than those who consumed the control polished rice (p < 0.05).

Short-Term Intake of Chlorogenic Acids Improves Psychomotor Speed and Motor Speed in Adults: A Randomized Crossover Trial

Chlorogenic acid (CGA), a polyphenolic compound found in various plants, has been reported to improve cognitive function. However, it remains unclear how long it takes for CGAs to exert their effects. Here, we evaluated the short-term effects of CGAs on cognitive function. We assessed the effects of 2-week CGA intake on cognitive function. The study was carried out as a randomized, double-blind, placebo-controlled, crossover trial. Twenty-six healthy Japanese participants (50–65 years of age) were randomly assigned to either the active beverage (CGAs: 270 mg) or the placebo beverage group daily for 2 weeks. After a 2-week washout period, the participants consumed the other beverages. We assessed cognitive function at baseline and following the first treatment period using the Japanese version of CNS Vital Signs. CGAs significantly improved the scores for psychomotor speed, motor speed, and right and left finger tapping compared to placebo. In addition, processing speed scores improved significantly from baseline only after CGA intake. In conclusion, CGAs were confirmed to improve cognitive function over a short period of two weeks.

Factors Associated With Hope and Quality of Life in Patients With Coronary Artery Disease

BACKGROUND

Psychological resources such as hope have been suggested to affect quality of life (QoL) positively in patients with heart disease. However, little information regarding the relationship between these two constructs is available.

PURPOSE

This work was aimed at examining the factors associated with hope and QoL in patients with coronary artery disease.

METHODS

In this descriptive work, perceived QoL and hope were assessed in 500 patients with heart disease. The information was collected using the McGill QoL Questionnaire, demographic variables, and the Herth Hope Index. The Pearson correlation test and general linear model were used to examine correlations through SPSS Version 22.

RESULTS

A considerable correlation was discovered between QoL and hope (r = .337, p < .001). Multivariate analyses with regression revealed that religious beliefs and social support both had significant and positive effects on the total perceived hope of patients and that patient age had a considerable negative impact on QoL (p < .05). None of these factors had a significant impact on hope (p < .05). In addition, the total QoL had a significant and positive effect on patient feelings and thoughts, whereas the physical problems component of QoL had a significant and negative effect on hope (p < .05). Participants with higher levels of education reported more hope.

CONCLUSIONS

QoL relates significantly to self-perceived hope in patients. Understanding QoL and hopefulness in patients with coronary artery disease has implications for nurses and other healthcare professionals.

Correlation between functional disability and quality of life among rural elderly in Anhui province, China: a cross-sectional study

Objective

We aimed to explore the correlation between functional disability and quality of life (QoL). And exploring the interaction of functional disability, basic demographic characteristics and health-related information on QoL among the rural elderly in Anhui Province.

Methods

This study used multi-stage stratified cluster sampling in rural Anhui Province from January to July 2018 to conduct a cross-sectional survey of older adults who met the inclusion criteria. The Five-Dimensional European Quality Of Health Scale (EQ-5D) and the WHO Disability Assessment Schedule (WHODAS2.0) scale were used to evaluate the QoL and functional disability, and the basic demographic characteristics of the survey subjects were also collected. Using binary logistic and Classification and regression tree model (CART) models to analyze the data, explore the relationship between functional disability and QoL in the elderly.

Results

A total of 3491 older adults were included in the survey, and 3336 completed the entire survey, with an effective response rate of 95.56%. After adjusting for covariables, those who had limited in dimension of mobility (AOR=2.243, 95%CI: 1.743-2.885), getting along (AOR=1.615, 95%CI: 1.173-2.226), life activities (AOR=2.494, 95%CI:1.928-3.226), and social participation (AOR=2.218, 95%CI: 1.656-2.971) had a lower QoL. However, the dimension of cognition (AOR=0.477, 95%CI: 0.372-0.613) is a protective factor for QoL. Additionally, we also observe that 96.3% of those who were unemployed and limited in both mobility and life activities dimensions had a lower QoL, but among those who were robust in both mobility and social participation dimensions and not suffer from chronic diseases, 56.3% had a higher QoL.

Conclusions

Our findings indicate that special attention should be paid to the elderly who are unemployed, have limited in cognition, getting along, social participation, mobility, life activities and cognition robust to improve their QoL. This research is of great significance for formulating targeted strategies and measures to improve the QoL for rural elderly.

Intensive Care-Related Cognitive Impairment: A Biopsychosocial Overview

Advancements in critical care medicine have improved survival rates for patients experiencing critical illness in intensive care units (ICUs). While mortality has declined, more than half of ICU survivors experience functional impairments that persist beyond discharge. Of particular concern is ICU-related cognitive impairment, which can extend across the care continuum, ranging from acute and transient presentations in the ICU (eg, delirium) to long-term impairments years after discharge. ICU-related cognitive impairment has received increased attention in the literature, particularly as it relates to ICU survivors who have received and survived critical care in the context of SARS-CoV-2 pandemic and are now experiencing post-acute sequelae of SARS-CoV-2 infection. The medical complexity and heterogeneity of ICU survivors, coupled with the multifactorial etiology of ICU-related cognitive impairments, lead to challenges in how to optimize care for ICU survivors at various stages of recovery. This review aims to provide an overview of cognitive outcomes associated with critical illness by integrating recent literature focused on etiology, assessment, and interventions in the context of ICU-related cognitive impairments. The narrative review employs a biopsychosocial framework to comprehensively evaluate the multifactorial nature of ICU-related cognitive outcomes. Authors also highlight multidisciplinary teams composed of key rehabilitation providers are likely best suited for optimizing recovery trajectories of ICU survivors.

Cognitive function, quality of life, and aging: relationships in individuals with and without spinal cord injury

Background: Correlations between aging, cognitive impairment and poor quality of life (QOL) have been observed for many patient populations.Objective: The purpose of this study was to examine these correlations in individuals with and without spinal cord injury (SCI).Methods: 23 individuals with complete SCI and 20 individuals without SCI ("NON") underwent assessment of cognitive function via the NIH Toolbox for Neurological and Behavioral Function. Participants self-rated QOL via global and symptom/domain-specific measures.Results: SCI rated global QOL to be lower than NON for the EQ-5D QALY (p < .001), but not the EQ-5D VAS, which imposes no penalty for wheeled mobility. Low QOL clustered mainly in domains pertaining to physical function/symptoms. Participants with SCI reported high QOL for positive affect/well-being and resilience. Cognitive function in SCI did not differ from NON. However, strong correlations between age and cognition observed in NON (all R² > 0.532) were absent in SCI. Significant correlations between cognition and QOL were prevalent for NON but not for SCI.Conclusions: Dissociation of age, cognition and QOL occurred with SCI. Divergence between EQ-5D QALY and VAS suggests that individuals with SCI may recalibrate personal assessments of QOL in ways that minimize the importance of mobility impairment.

A pilot study implementing the JAVA Music Club in residential care: impact on cognition and psychosocial health

BACKGROUND

Ninety percent of long-term care (LTC) residents experience some form of cognitive impairment. Social support may benefit cognition by decreasing depressive symptoms and loneliness, which are commonly reported among LTC residents.

OBJECTIVE

To investigate the effects of the Java Music Club (JMC), a manualized social support program, on cognition and psychosocial health among LTC residents using a pre-post mixed-methods approach.

METHODS

The JMC was implemented once a week for twelve weeks. Participants (n = 24, 91.7% female) completed cognitive tasks and psychosocial questionnaires before (T1), after (T2), and twelve weeks following (T3) participation in the JMC. Qualitative interviews were conducted at T2 with participants and recreation coordinators.

RESULTS

Analyses showed decreased loneliness from T1 to T2 (t = 3.31, p = .003) and reductions in depressive symptoms (F = 3.459, p = .043) and subjective memory complaints (F = 3.837, p = .048) from T2 to T3. Participants' qualitative interviews (N = 19) illustrate that the JMC was a positive experience that promoted social engagement. Important group elements included the group facilitator and group composition. Possible process elements included social engagement, the opportunity for reminiscence, and the ability of both social interaction and singing to benefit the residents and lift their 'spirits'. Recreation coordinators (N = 3) reported that the group was unlike currently available group programs and increased socialization between residents.

CONCLUSIONS

Participation in the JMC may be a promising approach to counter loneliness, depressive symptoms and subjective memory complaints in LTC residents.

"Where-There-Is-No-Psychiatrist Integrated Personal Therapy" among Community-Dwelling Older Adults: A Randomized Pilot Study

In Singapore, many older adults suffer from subsyndromal depression and/or subsyndromal anxiety, which can negatively impact their physical and mental well-being if left untreated. Due to the general public’s reluctance to seek psychological help and the low psychiatrist-to-population ratio in Singapore, this study aims to examine the preliminary efficacy, perceptions, and acceptability of a trained volunteer-led community-based intervention on community-dwelling older adults. Twenty-one participants (control: n = 11; intervention: n = 10) completed the randomized pilot study. A mixed-methods approach (questionnaires, semistructured interviews, examining blood samples, intervention fidelity) was adopted. No significant differences were found between the intervention and the control groups in depression, anxiety, life satisfaction, friendship, and quality of life. However, there was a positive change in quality-of-life scores from baseline to 6 months in the intervention group. The control group had significantly higher cortisol levels and lower annexin-A1 levels at 6 months, while the intervention group did not. Three themes emerged from the interviews: (1) impact of the intervention on older adults’ well-being, (2) attitudes toward intervention, and (3) a way forward. However, intervention efficacy could not be established due to small sample size caused by the coronavirus pandemic. Future randomized controlled trials should evaluate volunteer-led, technology-based psychosocial interventions to support these older adults.

The utility and cultural specificity of cognitive-based interventions in preventing cognitive decline among healthy older adults in Asia: A systematic review

BACKGROUND

The effects of aging and its associated cognitive decline is particularly acute in Asia given the exponential growth of older adults as a proportion of the population as a whole. Many structured cognitive interventions have been proposed to prevent the cognitive decline typically seen in older age, but their utility as a viable means of achieving these goals is questionable.

OBJECTIVES

To summarize and synthesize evidence on the utility and methodological quality of cognitive-based interventions on cognitive performance and associated secondary outcomes among healthy older adults in Asia, as well as novel, culture-specific components of cognitive interventions across the region.

DATA SOURCES

The PubMed/Medline, Web of Science, Scopus, and ScienceDirect databases were searched through May 2020.

ELIGIBILITY

Studies including individuals aged 60 years and above, who had no previous history of physical and/or mental illness. Few restrictions placed on intervention design, duration and mode of delivery, provided that participants were randomized to study conditions, and intervention included components addressing at least one cognitive domain.

RESULTS

A total of 17 studies from six countries met the eligibility criteria and were included in the final review. Evidence from those studies indicated that cognitive interventions may be most effective when the design and aims were directed towards improvement in specific cognitive domains, but evidence regarding long-term effectiveness in preventing progression to clinical-level cognitive deficits is still unclear. Several studies highlighted culture-specific activities as components of their interventions, though these will need to be further outlined and standardized clearly in future research.

Impact of Selected Geriatric Syndromes on the Quality of Life in the Population Aged 60 and Older

Background: Geriatric syndromes represent a critical domain in the population more than 60 years old. Basic syndromes include frailty, sarcopenia, loss of body mass, and a mild cognitive disorder. These are significant problems which can affect the quality of life. In our study, the Rapid Geriatric Assessment (RGA) tool was used to assess the geriatric syndromes, and the WHOQOL-BREF was used to assess the quality of life to survey 498 respondents from a population aged 60 and older. In all the assessments, the distribution of variables was tested, a nonnormal distribution of variables was identified, and subsequently, nonparametric tests were performed to identify the differences between groups. The study showed that the domain of physical health and the psychological domain were most affected. The results have shown that individual geriatric syndromes affect certain domains of the quality of life of the population above 60 with various intensity.

The Association Between the Changes in General, Family, and Financial Aspects of Quality of Life and Their Effects on Cognitive Function in an Elderly Population: The Korean Longitudinal Study of Aging, 2008-2016

Background The growing aging population is a global phenomenon and a major public health challenge. Among Organization for Economic Co-operation and Development countries, Korea is the fastest aging country. We aimed to investigate the relationship between changes in quality of life (QOL) and cognitive function in older adults. Method: Data from the Korean Longitudinal Study of Aging collected from 2008 to 2016 were used. In 3453 participants (men: 1943; women: 1541), QOL was measured by three aspects: general, financial, and familial. Changes in QOL status were assessed by four categories: remained poor, worsened, improved, and remained good. The level of cognitive function was measured by the Mini-Mental State Examination score (MMSE, normal range cut-off value: 24 or above). For the statistical analysis, the generalized equation model (GEE) was performed. Results: For all three aspects of QOL measured, participants whose QOL score remained poor were associated with cognitive decline that their odds ratios (OR) were statistically significant (general: OR = 1.33; familial: OR = 1.39; financial: OR = 1.40). For subgroup analysis by gender, the highest OR in men was the financial aspect of QOL (OR = 1.45); in women, the highest OR was the familial aspect of QOL (OR = 1.75). Conclusion: This study showed an association between QOL and cognitive function in a Korean elderly population. Our findings suggest that QOL measurements with a gender-specific approach can be used as a tool to detect cognitive changes in older adults and help prevent or delay cognitive decline.

The Effect of Foot Reflexology on Hospital Anxiety and Depression in Female Older Adults: a Randomized Controlled Trial

BACKGROUND

Patients with cardiovascular diseases usually suffer from hospital anxiety and depression.

AIM

This study aimed to investigate the effect of foot reflexology massage on anxiety and depression in female older adults suffering from acute coronary syndrome.

PARTICIPANTS

Ninety older women with acute coronary syndrome were randomly assigned into intervention and control groups (n=45 in each group).

RESEARCH DESIGN

A randomized controlled trial.

INTERVENTION

The intervention and control groups received foot reflexology massage and routine care, respectively.

MAIN OUTCOMES MEASURES

The levels of anxiety and depression were evaluated using the hospital's anxiety and depression scale (HADS) before and immediately after foot reflexology massage.

RESULTS

Foot reflexology massage reduced both anxiety (F(1.44)=19.11, p = .001) and depression (F(1.44)=16.76, p = .001) in acute coronary patients relative to control patients. The intervention had a large effect on hospital anxiety and depression.

CONCLUSIONS

Foot reflexology massage is an efficient and safe intervention for alleviating psychological responses among female older adults suffering from acute coronary syndrome during hospitalization.

Efficacy of Neurocognitive Rehabilitation After Coronary Artery Bypass Graft Surgery in Improving Quality of Life: An Interventional Trial

Introduction

Cognitive deficits are frequent after coronary artery bypass graft (CABG) surgery and consequently could lead to a decrease in quality of life. This is the first study that has been conducted with the aim of examining the efficacy of a computerized cognitive rehabilitation therapy (CCRT) in improving quality of life in patients after CABG surgery.

Methods

In this study, an interventional trial with pre-, post-, and follow-up assessments in active (CCRT), active control and control groups was conducted. Seventy-five patients after CABG surgery were selected and assigned to the groups (n = 25 for each group). CCRT consists of four modules of attention, working memory, response inhibition and processing speed training with graded schedule in 20-min sessions three times per week within 8 weeks. Cognitive functions (attention and working memory) were assessed by the tests of continuous performance, Flanker, useful field of view and digit span at three time points: pre- and post-intervention (T0 and T1) and 6-month follow-up (T2). Quality of life was assessed by the SF-36 questionnaire at the same time points. The CCRT group received the cognitive rehabilitation for 2 months, active control group received a sham version of CCRT in an equal time duration and control group did not receive any cognitive intervention.

Results

Repeated measures analysis of variance (ANOVA) revealed a time by group interaction on cognitive functions, with CCRT producing a significant improvement at T1 (p < 0.01) and these improvements were maintained at T2. Moreover, in CCRT and active control groups, quality of life (QoL) improved at T1 and these improvements remained stable throughout follow-up (T2). However, improvement of QoL in CCRT group was greater than improvement of QoL in the other two groups at T1. Pearson’s correlation analysis shows a positive correlation between QoL improvement and sustained attention and working memory enhancement (p < 0.05).

Conclusion

Cognitive rehabilitation can lead to a significant improvement in the cognitive functions that have been trained in patients receiving CABG. Interestingly enough, cognitive rehabilitation can also improve quality of life in patients after CABG surgery and this improvement is maintained for at least 6 months.

Quality of Life Enhancement Research Program: Lessons Learned

The attempted Quality of Life Enhancement program appeared to be a novel method for creating a symbiotic and sustainable relationship between a large Southeastern university and local nursing home and assisted living facilities (ALF), through which ALF residents would attend university arts and sporting events. During implementation, it was discovered that this project was unsustainable, undesired, unneeded by many care centers, difficult to implement, and required a dedicated and specialized staff. After attempting to enroll 14 local care facilities, only 2 were interested in becoming involved and produced 5 eligible participants. During the program itself, coordination with facilities and residents was difficult to maintain and unique transportation and accommodation needs were challenging to overcome. Finally, data collection was time consuming and generally unfruitful. Ultimately the project was discontinued after a year of attempted recruitment and implementation of inclusive changes to protocol. While creating an ongoing relationship with local care facilities and local universities may enhance opportunities for residents and research into important areas, such relationships take time, effort, and specialized staff to maintain.

The Role of Docosahexaenoic Acid (DHA) on Cognitive Functions in Psychiatric Disorders

Cognitive impairment is strongly associated with functional outcomes in psychiatric patients. Involvement of n-3 long chain polyunsaturated fatty acid (n-3 LC-PUFA), in particular docosahexaenoic acid (DHA), in brain functions is largely documented. DHA is incorporated into membrane phospholipids as structural component, especially in the central nervous system where it also has important functional effects. The aim of this review is to investigate the relationship between DHA and cognitive function in relation to mental disorders. Results from few randomized controlled trials (RCTs) on the effects of DHA (alone or in combination) in psychotic, mood and neurodevelopmental disorders, respectively, suggest that no conclusive remarks can be drawn.

Postoperative Cognitive Dysfunction after Coronary Artery Bypass Grafting

Postoperative cognitive dysfunction is a common complication following cardiac surgery. The incidence of cognitive dysfunction is more pronounced in patients receiving a cardiac operation than in those undergoing a non-cardiac operation. Clinical observations demonstrated that pulsatile flow was superior to nonpulsatile flow, and membrane oxygenator was superior to bubble oxygenator in terms of postoperative cognitive status. Nevertheless, cognitive assessments in patients receiving an on-pump and off-pump coronary artery bypass surgery have yielded inconsistent results. The exact mechanisms of postoperative cognitive dysfunction following coronary artery bypass grafting remain uncertain. The dual effects, neuroprotective and neurotoxic, of anesthetics should be thoroughly investigated. The diagnosis should be based on a comprehensive cognitive evaluation with neuropsychiatric tests, cerebral biomarker inspections, and electroencephalographic examination. The management strategies for cognitive dysfunction can be preventive or therapeutic. The preventive strategies of modifying surgical facilities and techniques can be effective for preventing the development of postoperative cognitive dysfunction. Investigational therapies may offer novel strategies of treatments. Anesthetic preconditioning might be helpful for the improvement of this dysfunction.

Social support as a mediator between depression and quality of life in Chinese community-dwelling older adults with chronic disease

The older adults with chronic disease usually show poor mental health and experience low quality of life (QOL). This study aimed to examine the mediating role of social support in the relationship between depression and QOL in community-dwelling older adults with chronic disease. A total of 387 Chinese older adults aged 60 or above with chronic disease were included in this cross-sectional study. Social support was negatively associated with depression and positively associated with physical component scale (PCS) and mental component scale (MCS). Depression and social support were all predictors of PCS and MCS. Mediation analysis suggested that social support partially mediated the impact of depression on PCS and MCS. Understanding the mediating role of social support might be beneficial in reducing the adverse impact of depression on QOL in community-dwelling older adults with chronic disease.

Effects of dropping out of dental treatment on the oral health-related quality of life among middle-aged subjects using web research

Objective

The oral health-related quality of life has recently been reported to be a rather important aspect of general health. Dropping out of dental treatment has long been a problem plaguing oral health. However, the relationship between dropout for dental treatment and the oral health-related quality of life is unclear. The purpose of this study was to investigate the oral health-related quality of life in patients who dropped out of dental treatment.

Materials and methods

We conducted a questionnaire-based investigation using web research. The participants were allocated to two groups (dropout group and maintenance group). The dropout group included participants who had stopped visiting their dental office in the past and had not revisited in the last decade. The maintenance group included patients who visited their dental office continually for a regular checkup. We analyzed the General Oral Health Assessment Index (GOHAI) as an indicator of the oral health-related quality of life and assessed the background characteristics of the subjects.

Results

We analyzed 225 people in the dropout group and 236 people in the maintenance group. The score of GOHAI was significantly different between the 2 groups (dropout group:47.07, maintenance:48.97, p = 0.035), and the more frequent dropouts brought the less GOHAI score (p = 0.012). Furthermore, the results of a logistic regression analysis showed that dropping out of dental treatment was significantly associated with the GOHAI score (p = 0.002).

Conclusion

A relationship was demonstrated between the oral health-related quality of life and dental treatment dropout. Furthermore, dental treatment dropout seemed to have negative effects on the oral health-related quality of life.

Strengthening the Brain-Is Resistance Training with Blood Flow Restriction an Effective Strategy for Cognitive Improvement?

Aging is accompanied by a decrease in physical capabilities (e.g., strength loss) and cognitive decline. The observed bidirectional relationship between physical activity and brain health suggests that physical activities could be beneficial to maintain and improve brain functioning (e.g., cognitive performance). However, the exercise type (e.g., resistance training, endurance training) and their exercise variables (e.g., load, duration, frequency) for an effective physical activity that optimally enhance cognitive performance are still unknown. There is growing evidence that resistance training induces substantial brain changes which contribute to improved cognitive functions. A relative new method in the field of resistance training is blood flow restriction training (BFR). While resistance training with BFR is widely studied in the context of muscular performance, this training strategy also induces an activation of signaling pathways associated with neuroplasticity and cognitive functions. Based on this, it seems reasonable to hypothesize that resistance training with BFR is a promising new strategy to boost the effectiveness of resistance training interventions regarding cognitive performance. To support our hypothesis, we provide rationales of possible adaptation processes induced by resistance training with BFR. Furthermore, we outline recommendations for future studies planning to investigate the effects of resistance training with BFR on cognition.

Effect of Chlorogenic Acids on Cognitive Function: A Randomized, Double-Blind, Placebo-Controlled Trial

(1) Background: Chlorogenic acids (CGAs) have been attracting interest of late, owing to their health benefits. Here, we performed a randomized, double-blind, placebo-controlled trial to investigate whether CGAs improved cognitive function in humans. (2) Methods: Thirty-eight healthy participants were assigned to either the CGA group, which was given CGA-added beverage daily for 16 weeks, or the placebo group. Cognitive functions were assessed using the Japanese version of the CNS Vital Signs (Cognitrax). (3) Results: The CGA group showed significant increase in the Cognitrax domain scores for motor speed, psychomotor speed, and executive function compared with the placebo group, as well as an improvement in the shifting attention test scores. In blood analysis, the CGA group showed increased levels of apolipoprotein A1 and transthyretin, both of which are putative biomarkers for early-stage cognitive decline. (4) Conclusions: These results suggest that CGAs may improve some cognitive functions, which would help in the efficient performance of complex tasks.

A prospective analysis of the role of cognition in three models of aging and schizophrenia

OBJECTIVES

This study uses longitudinal data from a sample of older adults with schizophrenia spectrum disorder (OAS) to examine the role of cognition in 3 models of aging and schizophrenia-accelerated aging, paradoxical aging, and heterogeneity of course-and their clinical relevance.

METHODS

The sample consisted of 103 community-dwelling persons aged 55 and over (mean=61years) with early-onset schizophrenia. Mean follow-up was 52.5months (range: 12-116months); 55% were men; 55% were white. We identified 21 potential predictor variables and used the Dementia Rating Scale (DRS) to assess cognition.

RESULTS

There were no significant differences in the DRS at baseline (T1) and follow-up (T2). However, 20%, 22% and 58% of persons exhibited >0.5 effect size increase or decrease, or no change in their DRS scores, respectively; 19% were rapid decliners (>-2.11pts/year) and 19% were rapid improvers (>+2.11pts/year). In multivariable analysis, there were 3 predictors of higher DRS (T2): DRS (T1), decline in anxiety score, and race (white).

CONCLUSIONS

The heterogeneity model best characterized the trajectory of cognition in later life. The accelerated aging model did not represent typical cognitive trajectories since most individuals were stable or improved. The heterogeneous trajectories made it difficult to generalize about cognition's role in the paradoxical aging model. Despite the paucity of predictors, our findings suggested that it may be clinically productive to enlist remediation strategies that target anxiety and cognition, and direct more attention to non-white OAS.

Association between age associated cognitive decline and health related quality of life among Iranian older individuals

Background

Age associated cognitive decline or normal cognitive aging is related with lower levels of functioning in real life, and may interfere with maintaining independence and health related quality of life (HRQL).

Objective

In this study, health related quality of life and cognitive function in community-dwelling older adults were evaluated with the aim of exploring the association between them by adjusting for potential confounders.

Methods

This cross-sectional study, was implemented on 425 community-dwelling older adults aged 60 and over, between August 2016 and October 2016 in health centers of the municipality of Tehran, Iran, using Mini Mental State Examination (MMSE) to assess cognitive function and Short Form-36 scales (SF-36) to assess HRQL. The relation between HRQL and cognitive function was evaluated by Pearson’s correlation coefficient, and the impact of cognitive function on HRQL adjusted for potential confounders was estimated by linear regression model. All analyses were done using SPSS, version 22.0.

Results

A positive significant correlation between cognitive function and quality of life (r=0.434; p<0.001) and its dimensions was observed. Two variables of educational level (B=2.704; 95% CI: 2.09 to 3.30; p<0.001) and depression (B=2.554; 95% CI: 2.00 to 3.10; p<0.001) were assumed as potential confounder by changing effect measure after entering the model. After adjusting for potential confounders in regression model, the association between MMSE scores and quality of life persisted (B=2.417; 95% CI: 1.86 to 2.96; p<0.001).

Conclusion

The results indicate that cognitive function was associated with HRQL in older adults with age associated cognitive function. Two variables of educational level and depression can affect the relation between cognitive decline and HRQL.

Social Support, Social Strain, and Cognitive Function Among Community-Dwelling U.S. Chinese Older Adults

Background

Limited research is available on the relationship between social support, social strain, and cognitive function among community-dwelling U.S. Chinese older adults. This study aims to examine the associations between social support/strain and cognitive outcomes.

Methods

Data were drawn from the Population-Based Study of Chinese Elderly (N = 3,159). Cognitive function was measured by a battery of tests including the East Boston Memory Test, the Digit Span Backwards assessment, and the Symbol Digit Modalities Test. Social support and strain were measured by the scales drawn from the Health and Retirement study. Multiple regression analyses were conducted.

Results

Social support was significantly associated with global cognitive function (β = .11, SE = .02, p < .001), episodic memory (β = .11, SE = .03, p < .001), working memory (β = .18, SE = .08, p < .05), and executive function (β = 1.44, SE = .37, p < .001). Social strain was significantly associated with global cognitive function (β = .23, SE = .05, p < .001), episodic memory (β = .27, SE = .07, p < .001), working memory (β = .34, SE = .17, p < .05), and executive function (β = 2.75, SE = .85, p < .01). In terms of sources of social support/strain, higher support from friends was significantly associated with higher global cognitive function (β = .04, SE = .02, p < .05), higher episodic memory (β = .05, SE = .02, p < .05), and higher executive function (β = .71, SE = .29, p < .05). Higher strain from spouse was significantly associated with higher global cognitive function (β = .10, SE = .03, p < .01), higher episodic memory (β = .11, SE = .04, p < .01), and higher executive function (β = 1.28, SE = .49, p < .01). Higher strain from friends was significantly associated with higher executive function (β = 3.59, SE = 1.17, p < .01).

Conclusions

Social support and strain were associated with cognitive outcomes. Future longitudinal studies should be conducted.

Serum Magnesium Status in Patients Subjects with Depression in the City of Yazd in Iran 2013-2014

Depression is the most common mental disorder and involves many factors. The regulatory effects of magnesium on N-methyl-D-aspartate (NMDA) channels make it a factor in the treatment of depression. The present study investigated the level of serum magnesium in subjects diagnosed with depression in the city of Yazd in Iran. This cross-sectional study was done from January 2013 to January 2014 on 650 patients with depression who agreed to participate in this study. Diagnosis was made using the Beck Depression Inventory test (BDI-II); those scoring higher than 11 were sent to the medical school laboratory for further testing of serum magnesium levels. The mean age of the patients was 34.16 ± 9.12 years. Of the 650 subjects, 195 were male (30 %) and 455 were female (70 %). The total mean serum magnesium was 2.1 ± 0.26 mg/dl. The prevalence of hypomagnesemia 13.7 %, hypermagnesemia 8.3 %, and sub-optimal magnesium levels was 26.5 %. Sub-optimal prevalence in women (28.1 %) was higher than in men (26.2 %). A significant relationship was observed between depression and serum magnesium level (p = 0.02). The results indicated that the prevalence of hypomagnesemia in subjects diagnosed with depression is high compared to non-depressed individuals. Moreover, there was a significant relationship between hypomagnesemia and intensity of depression that suggests a role for this element in the pathogenesis of the disorder. The high sub-optimal prevalence among women indicates that increased attention should be paid to this group.
