Rating chronic medical illness burden in geropsychiatric practice and research: application of the Cumulative Illness Rating Scale

The Impact of Dietary Intake and Physical Activity on Body Composition in Parkinson's Disease

BACKGROUND

Skeletal muscle loss has been associated with declining physical performance and a negative prognostic effect on falls, disability, and mortality risk in Parkinson's disease.

OBJECTIVES

We aimed to analyze the clinical correlates associated with skeletal muscle wasting in Parkinson's disease.

METHODS

This was a cross-sectional, case-control, observational study. We collected information on dietary intake with a 24-hour recall questionnaire, body composition with bioelectrical impedance, motor severity with the Unified Parkinson's disease Rating Scale, and physical activity with the Global Physical Activity Questionnaire. We used multivariate linear regression analysis to analyze the sociodemographic and clinical correlates associated with skeletal muscle loss after adjusting for confounding variables.

RESULTS

Forty-three patients with Parkinson's disease and 21 matched family members were included. Patients and family members had similar body composition, anthropometrics, and nutritional parameters. Advanced patients had similar nutrient intakes compared to patients with mild-to-moderate Parkinson's disease. In the multivariate linear regression analysis, female patients with low physical activity and low energy intake were more likely to have skeletal muscle loss.

CONCLUSIONS

Skeletal muscle wasting is a complex multifactorial problem. Dietary strategies and physical exercise should be recommended, especially to females with Parkinson's disease, to prevent significant skeletal muscle wasting.

Examining variation in the measurement of multimorbidity in research: a systematic review of 566 studies

BACKGROUND

A systematic understanding of how multimorbidity has been constructed and measured is unavailable. This review aimed to examine the definition and measurement of multimorbidity in peer-reviewed studies internationally.

METHODS

We systematically reviewed studies on multimorbidity, via a search of nine bibliographic databases (Ovid [PsycINFO, Embase, Global Health, and MEDLINE], Web of Science, the Cochrane Library, CINAHL Plus, Scopus, and ProQuest Dissertations & Theses Global), from inception to Jan 21, 2020. Reference lists and tracked citations of retrieved articles were hand-searched. Eligible studies were full-text articles measuring multimorbidity for any purpose in community, primary care, care home, or hospital populations receiving a non-specialist service. Abstracts, qualitative research, and case series were excluded. Two reviewers independently reviewed the retrieved studies with conflicts resolved by discussion or a third reviewer, and a single researcher extracted data from published papers. To assess our objectives of how multimorbidity has been measured and examine variation in the chronic conditions included (in terms of number and type), we used descriptive analysis (frequencies, cross-tabulation, and negative binomial regression) to summarise the characteristics of multimorbidity studies and measures (study setting, source of morbidity data, study population, primary study purpose, and multimorbidity measure type). This systematic review is registered with PROSPERO, CRD420201724090.

FINDINGS

566 studies were included in our review, of which 206 (36·4%) did not report a reference definition for multimorbidity and 73 (12·9%) did not report the conditions their measure included. The number of conditions included in measures ranged from two to 285 (median 17 [IQR 11-23). 452 (79·9%) studies reported types of condition within a single multimorbidity measure; most included at least one cardiovascular condition (441 [97·6%] of 452 studies), metabolic and endocrine condition (440 [97·3%]), respiratory condition (422 [93·4%]), musculoskeletal condition (396 [87·6%]), or mental health condition (355 [78·5%]) in their measure of multimorbidity. Chronic infections (123 [27·2%]), haematological conditions (110 [24·3%]), ear, nose, and throat conditions (107 [23·7%]), skin conditions (70 [15·5%]), oral conditions (19 [4·2%]), and congenital conditions (14 [3·1%]) were uncommonly included. Only eight individual conditions were included by more than half of studies in the multimorbidity measure used (diabetes, stroke, cancer, chronic obstructive pulmonary disease, hypertension, coronary heart disease, chronic kidney disease, and heart failure), with individual mental health conditions under-represented. Of the 566 studies, 419 were rated to be of moderate risk of bias, 107 of high risk of bias, and 40 of low risk of bias according to the Effective Public Health Practice Project quality assessment tool.

INTERPRETATION

Measurement of multimorbidity is poorly reported and highly variable. Consistent reporting of measure definitions should be required by journals, and consensus studies are needed to define core and study-dependent conditions to include in measures of multimorbidity.

Does the type of hip fracture affect functional recovery in elderly patients undergoing inpatient rehabilitation?

BACKGROUND

Hip fractures should not be considered as a single, homogeneous condition. Various determinants of functional recovery of patients with hip fracture have been proposed, such as age or type of fracture. The aim of this study was to determine if patients with an intertrochanteric fracture (ITF) had lower functional recovery characteristics with respect to those with a femoral neck fracture (FNF).

METHODS

A retrospective study was carried out on 531 elderly patients with hip fracture, surgically treated, admitted to a rehabilitation institute between December 1, 2014, and December 31, 2017. Patients underwent an individualized rehabilitation program for improving their physical function. The outcome measures of this study were the length of stay (LOS) in the rehabilitation institute, the Functional Independence Measure (FIM) gain, i.e. the difference in FIM score between discharge and admission, and the FIM efficiency, which represents the daily gain. Patients were also stratified by age categories and by different levels of functional independence, as evaluated with the FIM total score at baseline.

RESULTS

Age (p<0.05), LOS (p<0.005) and rehabilitation outcomes (FIM score and efficiency; p<0.05) differed significantly between patients with FNF and ITF. In particular, patients with ITF were older and more dependent at baseline. Moreover, they showed a lower FIM efficiency with respect to patients with FNF (p<0.05), which obtained a similar improvement in FIM total score of about 26 points but were discharged on average 3 days before. With aging, FIM efficiency decreased, while LOS increased. Patients highly dependent at baseline (FIM total score <40) had the lowest FIM gain and efficiency and the longest LOS respect to the more independent patients. Moreover, in older (85+ years) and in higher dependent patients the differences in the outcome measures between ITF and FNF were reduced.

CONCLUSIONS

The type of hip fracture could affect the LOS and FIM efficiency of younger and more independent patients with hip fracture during inpatient rehabilitation. In particular, patients with ITF require a longer rehabilitation period to achieve a similar functional gain as those with FNF.

Engagement in cognitively stimulating activities in individuals with Mild Cognitive Impairment: relationships with neuropsychological domains and hippocampal volume

Late-life participation in cognitively stimulating activities is thought to contribute to an individual's cognitive reserve and thus protect against cognitive decline, yet its association with clinical markers of neurodegeneration is not well established. To investigate, we developed a 13-item self-report "cognitively stimulating activities" questionnaire (CSA-Q), which was completed by a community sample of 269 older adults (>50 years) at risk of dementia. Participants met criteria for Mild Cognitive Impairment (MCI) and were classified as amnestic (aMCI; n = 93) or non-amnestic (naMCI; n = 176). Weighted CSA-Q dimensions were calculated for activity intensity, mental engagement and social engagement via a panel of 23 inter-raters. The CSA-Q mean and its dimensions were examined in relation to: (a) demographics (age, sex), (b) cognitive reserve proxies (years of education, premorbid IQ), (c) neuropsychological markers across cognitive domains of executive function, processing speed, learning, and memory storage, and (d) neuroimaging markers (left and right hippocampal volume). Analyses were conducted for all MCI, as well as for aMCI and naMCI sub-types. The CSA-Q was found to have concurrent validity with cognitive reserve proxies. Among all MCI, the CSA-Q dimensions of intensity and mental engagement had moderate associations with left hippocampal volume, but not with neuropsychological performance. For naMCI, the CSA-Q had moderate associations with left hippocampal volume, and small associations with aspects of executive functioning and processing speed. No equivalent associations emerged for the aMCI subtype. Our findings show that the CSA-Q may be particularly useful for older adults with non-amnestic cognitive deficits.

Multimorbidity and Regional Volumes of the Default Mode Network in Brain Aging

INTRODUCTION

The default mode network (DMN) is selectively vulnerable in brain aging. Little is known about the effect of multimorbidity as a whole onto the brain structural integrity.

OBJECTIVE

We aimed to investigate the association between multimorbidity and the structural integrity of DMN.

METHODS

We enrolled senior volunteers aged between 60 and 80 years in Hualien County during 2014-2018 and conducted in-person interview to collect information on chronic diseases. Fasting blood glucose and glycated hemoglobin (HbA1c) were tested. We assessed multimorbidity burden by the cumulative illness rating scale-geriatric (CIRS-G). MRI brain scans were standardized to measure the regional volume within the DMN. In a cross-sectional design, we employed stepwise regression models to evaluate the effects of age, sex, hyperglycemia, and multimorbidity on the DMN.

RESULTS

A total of 170 volunteers were enrolled with a mean age of 66.9 years, female preponderance (71%), an average mini-mental state examination score of 27.6, a mean HbA1c of 6.0, and a mean CIRS-G total score (TS) of 7.2. We found that older age was associated with reduced volumes in the hippocampus, left rostral anterior cingulate cortex, right posterior cingulate, right isthmus, precuneus, and right supramarginal. Higher levels of HbA1c and fasting glucose were associated with a reduced volume in the hippocampus only. A higher CIRS-G-TS was associated with reduced volumes in the left posterior cingulate cortex and right supramarginal gyrus; while a higher CIRS-G severity index was associated with a smaller right precuneus and right supramarginal.

CONCLUSIONS

In the DMN, hippocampal volume shows vulnerability to aging and hyperglycemia, whereas the posterior cingulate, supramarginal, and precuneus cortices may be the key sites to reflect the total effects of multimorbidity.

Executive Function Moderates Functional Outcomes of Engagement Strategies During Rehabilitation in Older Adults

OBJECTIVE

This study examined cognitive, affective, and medical impairments and their impact on rehabilitation approaches for improving functional outcome after hospitalization in older adults.

DESIGN

A secondary analysis of a randomized clinical trial in 229 adults 65 yrs or older admitted to two skilled nursing facilities undergoing rehabilitation services was conducted. Patients were randomized to receive physical and occupational therapy by therapists trained in systematic approaches to engage patients, called Enhanced Medical Rehabilitation, or standard of care. The outcome of interest was functional improvement, defined as Barthel Index at discharge (controlling for Barthel Index upon admission). This study analyzed the relationship of measures of cognition, depression, and medical comorbidities as predictors of functional outcome and as moderators interacting with treatment group.

RESULTS

Clock drawing score moderated treatment effect size; the functional improvement of Enhanced Medical Rehabilitation over standard of care therapy reduced with increasing executive impairment. In contrast, general cognitive abilities, depression, medical comorbidities, and readiness for rehabilitation were neither predictors nor moderators of functional improvement.

CONCLUSIONS

For older adults undergoing rehabilitation, greater functional improvement with the motivational techniques of Enhanced Medical Rehabilitation was contingent on patients having intact executive function. Given that executive function impairments are common in rehabilitation populations, new strategies are needed to improve treatment outcomes in physical/occupational therapy.

Effect of Home-Based Exercise Program on Physical Function and Balance in Older Adults With Sarcopenia: A Multicenter Randomized Controlled Study

In the prospective, randomized, controlled multicenter study, 100 patients who were clinically diagnosed with sarcopenia were assigned to either a home-based exercise group or a control group. The home-based training program included exercises with gradually increasing intensity comprising posture, stretching and upper- and lower-extremity muscle-strengthening exercises, balance and coordination exercises, and gait training. Before and 3 months after the exercise program, all the patients were evaluated. The 6-min walking test and Berg Balance Scale scores increased significantly after 3 months in the home-based exercise group compared with the controls. There was also a significant decrease in timed up and go test scores and a significant improvement in quality of life in the exercise group compared with the control group. Our findings indicated that a home-based exercise program can have a positive effect on physical function, balance, and quality of life in patients with sarcopenia.

Determinants of improved quality of life among older adults with multimorbidity receiving integrated outpatient services: A hospital-based retrospective cohort study

BACKGROUND

Older adults with multiple complex care needs tend to receive fragmented care that may jeopardize their quality of life (QoL) and health outcomes. This study evaluated the determinants of improved QoL among integrated outpatient service recipients with multimorbidity.

METHODS

We conducted a retrospective cohort study of integrated geriatric outpatient services (IGOS) at a tertiary medical center in Taiwan. Data from 2018 to 2019 were retrieved. All patients underwent comprehensive geriatric assessment, which included demographic information, serial functional assessments, and assessment for QoL. QoL was reassessed through a telephone survey 6 months after the patients' first visit to IGOS. Factors associated with the interval changes in QoL were identified using multivariate logistic regression.

RESULTS

Data from 995 patients receiving IGOS (mean age: 82.21 ± 7.96 years, 54.5% males) were analyzed. An overall mean improvement in QoL was noted (EQ-5D index: +0.055±0.26, p <0.001) while 747 recipients reported maintained or improved QoL. The results of the multivariate logistic regression showed that poorer nutritional status (OR = 1.56, 95% CI: 1.07-2.28), depressive symptoms (OR = 1.99, 95% CI: 1.38-2.86), and frailty (OR = 1.66, 95% CI: 1.10-2.52) were independent risk factors for poorer QoL after adjustment for baseline QoL.

CONCLUSIONS

Integrated outpatient services improved the quality of life of older adults with multimorbidity. Those with poorer nutritional status, depressive symptoms and frailty were less likely to show improvement in their QoL.

Association between lifetime depression history, hippocampal volume and memory in non-amnestic mild cognitive impairment

Hippocampal subfield volume loss in older adults with amnestic mild cognitive impairment (aMCI) and depression history are associated with amyloid beta and tau pathology, thereby increasing the risk for Alzheimer's disease (AD). However, no studies have exclusively examined distinct alterations in hippocampal subfields in non-amnestic MCI (naMCI) in relation to depression history. Here, we used both longitudinal and transverse hippocampal segmentation methods using the automated FreeSurfer software to examine whether a lifetime depression history is associated with differences in hippocampal head/body/tail (H/B/T) and key subfield volumes (CA1, subiculum, dentate gyrus) in older adults with naMCI. Further, we explored whether differences in hippocampal H/B/T and subfield volumes were associated with structured and unstructured verbal encoding and retention, comparing those with and without a depression history. The naMCI with a depression history group demonstrated larger or relatively preserved right CA1 volumes, which were associated with better unstructured verbal encoding and as well as structured verbal memory retention. This association between memory encoding and hippocampal CA1 and total head volume was significantly different to those with no depression history. The relationship between right CA1 volume and memory retention was also moderated by depression history status F (5,143) = 7.84, p < 0.001, R²  = 0.22. Those participants taking antidepressants had significantly larger hippocampal subiculum (p = 0.008), and right hippocampal body (p = 0.004) and better performance on structured encoding (p = 0.011) and unstructured memory retention (p = 0.009). These findings highlight the importance of lifetime depression history and antidepressant use on the hippocampus and encoding and memory retention in naMCI.

Pretransplant Comprehensive Geriatric Assessment in Older Patients with Advanced Chronic Kidney Disease

BACKGROUND

In older patients with advanced chronic kidney disease (CKD), the decision of kidney transplantation (KT) is a challenge for nephrologists. The use of comprehensive geriatric assessment (CGA) is increasingly gaining interest into the process of decision-making about treatment modality choice for CKD. The aim of this study was to assess the prevalence of geriatric impairment and frailty in older dialysis and nondialysis patients with advanced CKD using a pretransplant CGA model and to identify geriatric impairments influencing the geriatricians' recommendations for KT.

METHODS

An observational study was conducted with retrospective data from July 2017 to January 2020. Patients aged ≥65 years with advanced CKD, treated or not with dialysis, and referred by the nephrologist were included in the study. The CGA assessed comorbidity burden, cognition, mood, nutritional status, (instrumental) activities of daily living, physical function, frailty, and polypharmacy. Geriatric impairments influencing the geriatricians' recommendations for KT were identified using univariate and multivariate logistic regressions.

RESULTS

156 patients were included (74.2 ± 3.5 years and 62.2% on dialysis). Geriatric conditions were highly prevalent in both dialysis and nondialysis groups. The rate of geriatric impairments was higher in dialysis patients regarding comorbidity burden, symptoms of depression, physical function, autonomy, and frailty. Geriatrician's recommendations for KT were as follows: favorable (79.5%) versus not favorable or multidisciplinary discussion needed with nephrologists (20.5%). Dependence for Instrumental Activities of Daily Living (IADL) (odds ratio [OR] = 3.01 and 95% confidence interval [CI] = 1.30-7.31), physical functions (OR = 2.91 and 95% CI = 1.08-7.87), and frailty (OR = 2.66 and 95% CI = 1.07-6.65) were found to be independent geriatric impairments influencing geriatrician's recommendations for KT.

CONCLUSIONS

Understanding the burden of geriatric impairment provides an opportunity to direct KT decision-making and to guide interventions to prevent functional decline and preserve quality of life.

Impact of a Geriatric Intervention to Improve Screening and Management of Undernutrition in Older Patients Undergoing Surgery for Colorectal Cancer: Results of the ANC Stepped-Wedge Trial

Almost two in three patients who are aged 75 years and older and scheduled for surgery for colorectal cancer (CRC) are undernourished. Despite evidence that perioperative nutritional management can improve patients outcomes, international guidelines are still insufficiently applied in current practice. In this stepped-wedge cluster-randomized study of five surgical hospitals, we included 147 patients aged 70 years or older with scheduled abdominal surgery for CRC between October 2013 and December 2016. In the intervention condition, an outreach team comprising a geriatrician and a dietician visited patients and staff in surgical wards to assist with the correct application of guidelines. Evaluation, diagnosis, and prescription (according to nutritional status) were considered appropriate and strictly consistent with guidelines in 39.2% of patients in the intervention group compared to only 1.4% in the control group (p = 0.0002). Prescription of oral nutritional supplements during the perioperative period was significantly improved (41.9% vs. 4.1%; p < 0.0001). However, there were no benefits of the intervention on surgical complications or adverse events. A possible benefit of hospital stay reduction will need to be confirmed in further studies. This study highlights the importance of the implementation of quality improvement interventions into current practice for the perioperative nutritional management of older patients with CRC.

Reliability and Validity of Alzheimer's Disease Screening With a Semi-automated Smartphone Application Using Verbal Fluency

Introduction: This study aimed to examine the reliability and validity of Alzheimer's disease (AD) screening with a self-administered categorical verbal fluency test using a semi-automated Android application (app; tCVFT). Furthermore, its diagnostic accuracy concerning AD was compared with both that of a conventional categorical verbal fluency test (cCVFT) administered by a health professional and the Mini-Mental State Examination (MMSE).

Materials and Methods: Participants included 100 community-dwelling patients with early AD, whose Clinical Dementia Rating was either 0.5 or 1, and a further 100 sex-matched cognitively normal controls. The internal consistency and test-retest reliability of the tCVFT weighted sum score (tCVFT-WS) was examined using Cronbach's alpha and Pearson's correlation analyses (adjusted for age and education), respectively. The concurrent validity of the tCVFT-WS was examined by testing its correlations with the cCVFT weighted sum score (cCVFT-WS) and MMSE using Pearson's correlation tests. The diagnostic accuracies for early AD of the tCVFT-WS, cCVFT-WS, and MMSE were estimated and compared using receiver operating characteristic (ROC) analyses.

Results: The tCVFT-WS exhibited strong internal consistency (Cronbach's alpha = 0.79). However, its test-retest reliability was moderate (r = 0.54) owing to the low test-retest reliability of the second-half responses. The patient group exhibited a higher tCVFT-WS than the control group (p < 0.001). Correlations between the tCVFT-WS, cCVFT-WS, and MMSE were significant. The tCVFT-WS's area under the ROC curve for AD was 0.861. At its optimal cutoff, the sensitivity and specificity for AD were 0.78 and 0.77, respectively.

Conclusions: The self-administered tCVFT-WS, using an Android app, proved valid and reliable at distinguishing people with early AD from cognitively normal controls.

Association between plasma monocyte trafficking-related molecules and future risk of depression in older adults

BACKGROUND

The recruitment of monocytes to the brain plays an important role in the development of depression. However, the association between plasma biomarkers of monocyte trafficking and depression is unclear. This study is aimed to examine the effects of plasma monocyte chemoattractant protein-1 (MCP-1), intercellular adhesion molecule-1 (ICAM-1), and vascular cell adhesion molecule-1 (VCAM-1) on the risk of depression.

METHODS

Data were acquired from an ongoing prospective cohort study involving randomly sampled, community-dwelling Korean older adults, which has been followed every two years. We included 1,539 euthymic older adults (age = 68.2 [5.6] years; 51.7% were women) without a history of major psychiatric disorders, and dementia and neurological diseases. Geriatric psychiatrists diagnosed incident depression through a structured interview using the Korean version of the Mini International Neuropsychiatric Interview.

RESULTS

Depression had developed in 134 (8.7 %) participants during the follow-up period of 5.7 (0.8) years. The high plasma MCP-1 tertile group showed two-fold higher risk of depression than the low plasma MCP-1 tertile group (hazards ratio [HR] = 2.00, 95% confidence intervals [CI] = 1.27 - 3.13, p = 0.003). The association between high levels of plasma MCP-1 and future risk of depression was significant in the middle plasma ICAM-1 and VCAM-1 tertile groups; the high plasma MCP-1 tertile group showed about four-fold higher risk of depression than the low plasma MCP-1 tertile group.

CONCLUSIONS

Molecules involved in monocyte trafficking may be good candidates as diagnostic biomarkers and/or therapeutic targets for late life depression.

Longitudinal, Interdisciplinary Home Visits vs. Usual Care for Homebound People with Advanced Parkinson's Disease (IN-HOME-PD): Study protocol for a controlled trial

Background

The current understanding of advanced Parkinson disease (PD) and its treatment is largely based on data from outpatient visits. The most advanced and disabled individuals with PD are disconnected from both care and research. A previous pilot study among older, multimorbid patients with advanced PD demonstrated the feasibility of interdisciplinary home visits to reach the target population, improve care quality, and potentially avoid institutionalization.

Objective

The aim of this study protocol is to investigate whether interdisciplinary home visits can prevent a decline in quality of life of patients with PD and prevent worsening of caregiver strain. The protocol also explores whether program costs are offset by savings in health care utilization and institutionalization compared with usual care.

Methods

In this single-center, controlled trial, 65 patient-caregiver dyads affected by advanced PD (Hoehn and Yahr stages 3-5 and homebound) are recruited to receive quarterly interdisciplinary home visits over 1 year. The 1-year intervention is delivered by a nurse and a research coordinator, who travel to the home, and it is supported by a movement disorder specialist and social worker (both present by video). Each dyad is compared with age-, sex-, and Hoehn and Yahr stage–matched control dyads drawn from US participants in the longitudinal Parkinson’s Outcome Project registry. The primary outcome measure is the change in patient quality of life between baseline and 1 year. Secondary outcome measures include changes in Hoehn and Yahr stage, caregiver strain, self-reported fall frequency, emergency room visits, hospital admissions, and time to institutionalization or death. Intervention costs and changes in health care utilization will be analyzed in a budget impact analysis to explore the potential for model adaptation and dissemination.

Results

The protocol was funded in September 2017 and approved by the Rush Institutional Review Board in October 2017. Recruitment began in May 2018 and closed in November 2019 with 65 patient-caregiver dyads enrolled. All study visits have been completed, and analysis is underway.

Conclusions

To our knowledge, this is the first controlled trial to investigate the effects of interdisciplinary home visits among homebound individuals with advanced PD and their caregivers. This study also establishes a unique cohort of patients from whom we can study the natural course of advanced PD, its treatments, and unmet needs.

Disease Burdens of Alzheimer's Disease, Vascular Dementia, and Mild Cognitive Impairment

OBJECTIVES

Understanding disability-adjusted life-years (DALYs) based on dementia subtypes and mild cognitive impairment (MCI) is essential for optimal resource allocation. This study aimed to investigate disease burdens of various dementias and MCI in a representative South Korean population.

DESIGN

Retrospective cohort study.

SETTING AND PARTICIPANTS

6481 Korean older adults.

METHODS

We estimated the disease-specific DALYs.

RESULTS

DALYs due to MCI and all-cause dementia are estimated to increase from 1295 per 100,000 in 2016 to 9501 per 100,000 in 2065. In 2016, DALYs attributed to Alzheimer's dementia, vascular dementia, and MCI accounted for 33% (423 per 100,000), 20% (316 per 100,000), and 24% (123 per 100,000), respectively, of the total DALYs due to MCI and all-cause dementia. In 2065, DALYs due to Alzheimer's dementia, vascular dementia, and MCI will account for 38% (3654 per 100,000), 17% (1654 per 100,000), and 27% (2585 per 100,000) of total DALYs due to MCI and all-cause dementia, respectively. The years of life lived with disability (YLDs) due to MCI and all-cause dementia are estimated to rise from 479 per 100,000 in 2016 to 2807 per 100,000 in 2065. In 2016, YLDs due to Alzheimer's dementia, vascular dementia, and MCI composed 37% (177 per 100,000), 18% (85 per 100,000), and 15% (70 per 100,000), respectively, of the total YLDs due to MCI and all-cause dementia. In 2065, YLDs due to Alzheimer's dementia, vascular dementia, and MCI will account for 48% (1358 per 100,000), 15% (410 per 100,000), and 10% (290 per 100,000), respectively, of total YLDs due to MCI and all-cause dementia.

CONCLUSIONS AND IMPLICATIONS

Considering the rapidly growing disease burden, resources should be allocated to continuously monitor and manage the MCI and dementia burden. Particular attention to Alzheimer's dementia is required considering its significant contribution to current and future disease burden, especially to YLD.

A 10-Item Frailty Index Based on a Comprehensive Geriatric Assessment (FI-CGA-10) in Older Adults with Cancer: Development and Construct Validation

BACKGROUND

A frailty index (FI) based on domain-level deficits identified through a comprehensive geriatric assessment (CGA) has been previously developed and validated in general geriatric patients. Our objectives were to construct an FI-CGA and to assess its construct validity in the geriatric oncology setting.

METHODS

Five hundred forty consecutive Japanese patients with cancer who underwent a CGA on a geriatric oncology service were included (median age 80 years, range 66-96 years). We developed a 10-item frailty index based on deficits in 10 domains (FI-CGA-10): cognition, mood, communication, mobility, balance, nutrition, basic and instrumental activities of daily living, social support, and comorbidity. Deficits in each domain were scored as 0 (no problem), 0.5 (minor problem), and 1.0 (major problem). Scores were calculated by dividing the sum of the scores for each domain by 10 and then categorized as fit (<0.2), pre-frail (0.2-0.35), and frail (>0.35). Construct validity was tested by correlating the FI-CGA-10 with other established frailty measures.

RESULTS

FI-CGA-10 was well approximated by the gamma distribution. Overall, 20% of patients were fit, 41% were pre-frail, and 39% were frail. FI-CGA-10 was correlated with Canadian Study of Health and Aging (CSHA) Clinical Frailty Scale (r = 0.83), CSHA rules-based frailty definition (r = 0.67), and CSHA Function Score (r = 0.77). Increasing levels of frailty were significantly associated with functional and cognitive impairments, high comorbidity burden, poor self-rated health, and low estimated survival probabilities.

CONCLUSION

The FI-CGA-10 is a user-friendly and construct-validated measure for quantifying frailty from a CGA.

IMPLICATIONS FOR PRACTICE

This article describes the construction of a user-friendly 10-item frailty index based on a comprehensive geriatric assessment (FI-CGA-10) for older adults with cancer: cognition, mood, communication, mobility, balance, nutrition, basic and instrumental activities of daily living, social support, and comorbidity. The FI-CGA-10 simplifies the original FI-CGA used in the general geriatric setting while maintaining its content validity. The index's construct validity was demonstrated in a cohort of older adults with various cancer types. The advantage of the FI-CGA-10 is that a frailty score can be calculated more readily and interpreted in a more clinically sensible manner than the original FI-CGA.

Effect of Older vs Younger Age on Anthropometric and Metabolic Variables During Treatment of Psychotic Depression With Sertraline Plus Olanzapine: The STOP-PD II Study

OBJECTIVE

To examine the effect of older versus younger age on change in anthropometric and metabolic measures during extended treatment of psychotic depression with sertraline plus olanzapine.

METHODS

Two hundred and sixty-nine men and women aged 18-85 years with an episode of psychotic depression were treated with open-label sertraline plus olanzapine for up to 12 weeks. Participants who remained in remission following an 8-week stabilization phase were eligible to participate in a 36-week randomized controlled trial (RCT) that compared the efficacy and tolerability of sertraline plus olanzapine with sertraline plus placebo. Weight, waist circumference and plasma lipids, glucose, HbA1c, and insulin were measured at regular intervals during the acute, stabilization and randomized phases of the study. Linear mixed models were used to analyze the trajectories of anthropometric and metabolic measures.

RESULTS

Participants aged 60 years or older experienced less weight gain and less increase in cholesterol during the combined acute and stabilization phases of the study compared with those aged 18-59 years. At the acute-stabilization termination visit, mean weight in older participants was 6.5 lb. less than premorbid weight, whereas it was 17.9 lb. more than premorbid weight in younger participants. In the RCT, there was a significant interaction of treatment and age group for the trajectory of weight, but the post hoc tests that compared age groups within each treatment arm were not statistically significant. There were no clinically significant differences between younger and older participants in glycemic measures.

CONCLUSION

Older patients with psychotic depression experienced less increase in weight and total cholesterol than their younger counterparts during acute and stabilization treatment with sertraline plus olanzapine. In the older group, weight gained during the acute and stabilization phases appeared to be partial restoration of weight lost during the index episode of depression, whereas weight gain in younger participants was not.

Resilience in severe mental disorders: correlations to clinical measures and quality of life in hospitalized patients with major depression, bipolar disorder, and schizophrenia

PURPOSE

To evaluate resilience in severe mental disorders and correlate it with clinical measures and quality of life.

METHODS

Resilience (Resilience Scale, RS) and quality of life (WHOQOL-BREF questionnaire) were prospectively evaluated in a sample of 384 hospitalized patients diagnosed with severe mental disorders (depression, bipolar disorder and schizophrenia). Clinical outcomes were measured using the Global Assessment of Functioning Scale (GAF), Clinical Global Impression (CGI), Cumulative Illness Rating Scale (CIRS), Hamilton Scale-Depression (HAM-D), Young Mania Rating Scale (YMRS), and Brief Psychiatric Rating Scale (BPRS).

RESULTS

Resilience measure showed a difference between the three clinical groups analyzed in the study, with lower scores in depressed patients than in bipolar disorder or schizophrenia patients. There was a trend toward a correlation between resilience and depressive symptoms (Hamilton Scale-Depression; P = 0.052; r_s = - 0.163). The scores in the resilience scale's personal competence domain presented a tendency of association with general psychiatric symptoms (Brief Psychiatric Rating Scale; P = 0.058; r = - 0.138). There was a significantly positive association between resilience and all domains of quality of life (r = 0.306-0.545; P < 0.05). Sociodemographic data like age, education, intelligence quotient, sex, and marital status were associated with resilience.

CONCLUSION

Depressive patients had low scores on the resilience scale compared to patients with other disorders. Resilience was positively associated with quality of life. Therefore, it deserves special attention, as it promotes more positive outcomes and improves patients' quality of life with severe mental disorders.

Mealtime caregiving approaches and behavioral symptoms in persons living with dementia: a longitudinal, observational study

Background

Behavioral symptoms during mealtime can prohibit persons living with dementia from obtaining sufficient nutrition. However, little research has examined the relationship between behavioral symptoms and caregiving approaches. This study examines this relationship and further explores which specific caregiver behaviors were related to behavioral symptoms among persons living with dementia.

Methods

A secondary data analysis was performed using 86 mealtime videos from a longitudinal, observational study. The videos were repeatedly taken at months 0, 3, and 6 with 30 persons living with dementia in one of four long-term care facilities. Video coding was performed using coding schemes modified from the Cohen-Mansfield Agitation Inventory for behavioral symptoms and the Person-/Task-Centered Behavior Inventory for caregiving approaches. Coding schemes for behavioral symptoms consisted of four categories: total duration, aggressive behavior, physically nonaggressive behavior, and verbally agitated behavior. Caregiving approaches consisted of ten-verbal/seven-nonverbal person-centered behavior codes, four-verbal/four-nonverbal task-centered behavior codes, and no-verbal/no-nonverbal interaction codes. A mixed-effect model was conducted using variables such as demographics, medical information, cognitive status, depression, function, and caregiving approaches as fixed effects, participant as a random effect, and four categories of behavioral symptoms as dependent variables.

Results

The total duration of the Cohen-Mansfield Agitation Inventory was associated with no verbal response (β = 9.09) and task-centered verbal behavior (β = 8.43), specifically verbal controlling (β = 7.87). Physically nonaggressive behavior was associated with no verbal response (β = 9.36). Verbally agitated behavior was associated with task-centered nonverbal behavior (β = 51.29), and specifically inappropriate touch (β = 59.05).

Conclusions

Mealtime is indispensable to dementia care for ensuring adequate nutrition and promoting personhood. Our findings revealed caregivers’ task-centered behaviors and no interaction were related to behavioral symptoms of persons living with dementia. When caregivers encounter behavioral symptoms during mealtime, it is recommended to avoid no response and task-centered behaviors, especially verbal controlling and inappropriate touch, and to promote person-centered behaviors.

Trajectories of functional performance recovery after inpatient geriatric rehabilitation: an observational study

Objective

To identify functional performance trajectories and the characteristics of people who receive inpatient geriatric rehabilitation after hospital admissions.

Design, setting, participants

REStORing health of acutely unwell adulTs (RESORT) is an observational, prospective, longitudinal inception cohort study of consecutive patients admitted to geriatric rehabilitation wards at the Royal Melbourne Hospital. Recruitment commenced on 15 October 2017.

Main outcome measures

Functional performance, assessed with the Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) scales two weeks before acute hospitalisation, on admission to and discharge from geriatric rehabilitation, and three months after discharge from geriatric rehabilitation.

Results

A total of 618 rehabilitation patients were included in our analysis. For each of the two scales, three distinct functional performance trajectories were identified by latent class growth modelling: poor at baseline and 3‐month follow‐up (remained poor: ADL, 6.6% of patients; IADL, 42%), good at baseline but poor recovery (deteriorated: ADL, 33%; IADL, 20%), and good at baseline and good recovery (recovered: ADL, 60%; IADL, 35%). Higher Clinical Frailty Scale (CFS) score (v recovered, per point: odds ratio [OR], 2.51; 95% CI, 1.64–3.84) and cognitive impairment (OR, 6.33; 95% CI, 2.09–19.1) were associated with greater likelihood of remaining poor in ADL, and also with deterioration (CFS score: OR, 1.76; 95% CI, 1.45–2.13; cognitive impairment: OR, 1.87; 95% CI, 1.24–2.82). Higher CFS score (OR, 1.64; 95% CI, 1.37–1.97) and cognitive impairment (OR, 3.60; 95% CI, 2.31–5.61) were associated with remaining poor in IADL, and higher CFS score was also associated with deterioration (OR, 1.63; 95% CI, 1.33–1.99).

Conclusions

Based on ADL assessments, most people who underwent inpatient geriatric rehabilitation regained their baseline functional performance. As higher CFS score and cognitive impairment were associated with poorer functional recovery, assessing frailty and cognition at hospital admission could assist intervention and discharge planning.

Individualised physical activity programme in patients over 65 years with haematological malignancies (OCAPI): protocol for a single-arm feasibility trial

INTRODUCTION

Older adults with cancer suffer from the combined effects of ageing, cancer disease and treatment side effects. The main treatment for patients with haematological malignancies is chemotherapy, associated with significant toxicities. Chemotherapy can alter patients' physical function and quality of life which are often already diminished in older patients due to ageing and comorbidities. It therefore seems essential to develop and to evaluate interventions capable of preventing physical and psychosocial decline and its consequences. Promoting physical activity is a promising approach to improve physical function and quality of life in older adults with cancer, but there are limited data on the feasibility of such interventions among older patients with haematological malignancies, concomitant to chemotherapy.

METHODS AND ANALYSIS

OCAPI (OnCogeriatric and Individualized Physical Activity) is a single-arm, interdisciplinary, prospective, interventional, feasibility study. It is intended to include 40 patients (20 patients with acute myeloid leukaemia and 20 patients with non-Hodgkin's lymphoma) over 65 years in an individualised 6-month physical activity programme. The programme consists of individually supervised exercise sessions with an increasing volume of physical activity either at home and/or in a laminar airflow room (depending on the disease and treatment regimen) followed by unsupervised sessions and phone follow-ups. Patients will receive an activity tracker during the 6 months of the programme. Evaluations will take place at inclusion and at 3, 6 and 12 months to assess the feasibility of the programme and to explore potential changes in physical, psychosocial and clinical outcomes. The results will generate preliminary data to implement a larger randomised controlled trial.

ETHICS AND DISSEMINATION

The study protocol was approved by the French ethics committee (Comité de protection des personnes Est I, N°ID-RCB 2019-A01231-56, 12 July 2019). All participants will have to sign and date an informed consent form. The findings will be disseminated in peer-reviewed journals and academic conferences.

Poorer Theory of Mind in Amnestic Mild Cognitive Impairment Is Associated with Decreased Functional Connectivity in the Default Mode Network

BACKGROUND

Older adults living with amnestic mild cognitive impairment (aMCI) not only demonstrate impairments in Theory of Mind (ToM), relative to adults with non-amnestic MCI (naMCI), but are also at a higher risk of developing dementia.

OBJECTIVE

Our primary objective was to ascertain whether default mode network (DMN) functional connectivity was differentially associated with ToM abilities between MCI subgroups.

METHODS

Using functional magnetic resonance imaging, we investigated alterations in resting-state functional connectivity within the brain's DMN in a sample of 43 older adults with aMCI (n = 19) and naMCI (n = 24), previously reported to demonstrate poorer ToM abilities.

RESULTS

Compared to naMCI, the aMCI subgroup revealed a significant association between poorer ToM performance and reduced functional connectivity between the bilateral temporal pole (TempP) and the left lateral temporal cortex (LTC) (LTC_L-TempP_L: b = -0.06, t(33) = -3.53, p = 0.02; LTC_L-TempP_R: b = -0.07,t(33) = -3.20, p = 0.03); between the right TempP and the dorsal medial prefrontal cortex (dMPFC) (b = -0.04, t(33) = -3.02, p = 0.03) and between the left and right TempP (b = -0.05, t(33) = -3.26, p = 0.03). In the naMCI subgroup, the opposite relationship was present between the bilateral TempP and the left LTC (Combined correlation: r = -0.47, p = 0.02), however, not between the right TempP and the dMPFC (r = -0.14, p = 0.51) or the left and right TempP (r = -0.31, p = 0.14).

CONCLUSION

Our findings suggest that alterations in functional connectivity within the DMN involving temporal and frontal lobe regions are associated with ToM deficits in aMCI.

An examination of reciprocal effects between cardiovascular morbidity, depressive symptoms and loneliness over time in a longitudinal cohort of Dutch older adults

BACKGROUND

Unidirectional studies suggest that the effects between cardiovascular disease, depressive symptoms and loneliness are reciprocal, but this has not been tested empirically. The aim was to study how cardiovascular morbidity, depressive symptoms and loneliness influence each other longitudinally.

METHODS

Data from 2979 older adults from the Longitudinal Aging Study Amsterdam were analysed. Depressive symptoms (≥16 points on the Center for Epidemiologic Studies Depression Scale), loneliness (≥3 points on the De Jong Gierveld Loneliness Scale) and cardiovascular morbidity were measured five times during 13-year follow-up. With structural equation modelling, a full cross-lagged panel model was compared to nine nested models reflecting different sets of temporal effects.

RESULTS

The best-fitting cross-lagged panel model showed reciprocal risk increasing effects between depressive symptoms and loneliness and a risk increasing effect of cardiovascular morbidity on depressive symptoms.

LIMITATIONS

A cross-lagged panel model has technical limitations, such as that the chosen time lag may not be appropriate for each effect. In addition, differential loss to follow-up and collider bias may have led to an underestimation of the effects.

CONCLUSIONS

Reciprocal effects tend to occur only between depressive symptoms and loneliness. Their interplay with cardiovascular morbidity seems more complex and mostly indirect, highlighting the potential of interventions to reduce depressive symptoms, loneliness and cardiovascular morbidity in concert to improve health at old age.

Current Treatment Options in CLL

After impressive developments in recent years with the rise of new targeted agents, chemoimmunotherapy (CIT) only plays a minor role in the treatment of patients with chronic lymphocytic leukemia (CLL). Inhibitors of the Bruton tyrosine kinase (BTK), such as ibrutinib or more recently acalabrutinib, are highly effective, even in poor-risk or chemo-refractory patients. Venetoclax, an inhibitor of the anti-apoptotic BCL2 protein and, to a lesser extent, phosphoinositide-3 kinase (PI3K) delta inhibitors, add to the armamentarium of targeted agents for the treatment of CLL. Furthermore, anti-CD20 monoclonal antibodies are used very successfully either alone or in combination with BTK, BCL2 or PI3K inhibitors. Despite these advances, there is still an ongoing pursuit for new therapeutic approaches in the treatment of CLL. An even bigger challenge poses the determination of the optimal combination and sequence of those drugs. Here, we give an overview of current treatment options in CLL, weighing the advantages and disadvantages of each approach in the light of different clinical settings.

Postoperative Delirium is Not Associated with Long-Term Decline in Activities of Daily Living or Mortality After Laryngectomy

Purpose

To determine the relationships between postoperative delirium (POD) and postoperative activities of daily living (ADL) and mortality in patients undergoing laryngectomy. We hypothesized that POD would reduce postoperative ADL and increase postoperative mortality.

Patients and Methods

The prospective study included older participants (age ≥65 y) undergoing total laryngectomy, partial laryngectomy, total laryngectomy plus neck dissection, or partial laryngectomy plus neck dissection under general anesthesia. The diagnosis of delirium was based on the Confusion Assessment Method algorithm, which was administered on postoperative days 1 through 6. ADL were evaluated using the Chinese version of the Index of ADL scale. Follow-up assessments of ADL and mortality were conducted 24 months after surgery.

Results

Of 127 participants (aged 70.3 ± 4.1 y), 19 (15.0%) developed POD. POD was not associated with a decrease in ADL after laryngectomy (p=0.599) nor with an increase in postoperative mortality [3/19 (15.8%) vs 12/108 (11.1%), p=0.560, Log rank test]. However, longer surgery duration was significantly associated with worse overall survival (OR, 3.262; 95% CI, 1.261–9.169, p=0.025).

Conclusion

POD was not associated with long-term ADL or mortality after laryngectomy. Prolonged surgery was the only factor associated with a higher postoperative mortality rate.

Association between gait speed and the SHARE Frailty Instrument in a Falls and Syncope Clinic

PURPOSE

Identifying physical frailty is useful in the context of falls and syncope assessment. The phenotype-based SHARE Frailty Instrument for Primary Care (SHARE-FI) does not measure gait speed. We evaluated the association between SHARE-FI and gait speed in a Falls' and Syncope Unit (FASU).

METHODS

We recruited a pilot sample of patients aged 50 and over attending FASU between November 2019 and March 2020. The association between gait speed and SHARE-FI was assessed with the Spearman's co-efficient (r_s). Logistic regression was conducted to investigate the association controlling for age, sex, body mass index, comorbidities and polypharmacy.

RESULTS

104 participants were included (34 frail) median (IQR) age 74 (68-79) years. 68 were female. There was a significant negative correlation between frailty and gait speed (r_s - 0.54, P < 0.001). In the multivariable model, gait speed remained independently associated with frailty (OR 0.09, 95% CI 0.02-0.52, P = 0.007).

CONCLUSIONS

SHARE-FI significantly captured gait speed in this clinical sample, adding to its validity.

Associations between the Geriatric-8 and 4-meter gait speed test and subsequent delivery of adjuvant chemotherapy in older patients with colon cancer

OBJECTIVES

Feasible screening methods are important to identify older patients who might benefit from adjuvant chemotherapy. The aim of this study was to investigate the associations between the outcomes of screening for frailty with the Geriatric-8 questionnaire (G8) and the 4-meter gait speed test (4MGST) and subsequent delivery of adjuvant chemotherapy and treatment tolerance in older patients with colon cancer.

MATERIAL AND METHODS

This retrospective multicentre study included all patients aged ≥70 with primary colon carcinoma who underwent elective surgery between May 2016 and December 2018 and for whom adjuvant chemotherapy was indicated. Data were analysed using multivariate regression models.

RESULTS

97 (73.5%) of 132 eligible patients were screened by the G8 and 85 (64.4%) by the 4MGST. In univariate analyses, patients who scored indicative for frailty on both the G8 (≤14) and the 4MGST (>4 s) significantly more often did not proceed with adjuvant chemotherapy than patients who scored fit on both instruments (OR = 5.10, p = 0.01). After adjustment for gender, stage, and postoperative complications, the OR decreased to 4.22 (p = 0.04). Tolerance of treatment was very high (93%) and did not differ between screening groups.

CONCLUSION

Although patients who scored indicative for frailty on both the G8 and the 4MGST significantly more often did not proceed with adjuvant chemotherapy, it is still unknown whether the G8 and the 4MGST are reliable tools for identifying patients who are at high risk for severe chemotoxicity. Nonetheless, this study shows that current selection for adjuvant chemotherapy among older patients with colon cancer is safe with low rates of severe chemotoxicity.

Sleep-Dependent Memory in Older People With and Without MCI: The Relevance of Sleep Microarchitecture, OSA, Hippocampal Subfields, and Episodic Memory

This study aimed to determine if, relative to cognitively healthy controls, sleep-dependent memory consolidation (SDMC) is diminished in mild cognitive impairment (MCI), a group at high risk of conversion to dementia. We also sought to determine whether SDMC is associated with sleep characteristics, daytime episodic memory, and hippocampal integrity. Participants with MCI (n = 43) and controls (n = 20) underwent clinical and neuropsychological profiling. From polysomnography, apnea hypopnea index (AHI) and non-REM sleep spindle characteristics were derived. From magnetic resonance imaging, hippocampal subfield volumes were computed. Participants learned a novel 32-item word-pair prior to sleep; morning retention of the word-pairs was used to determine SDMC. Results showed that SDMC did not differ between MCI and controls, but there was a large effect size decrement in SDMC in those with multiple domain MCI (Hedge's g = 0.85). In MCI, poorer SDMC was correlated with CA1 and CA3 hippocampal atrophy, shorter spindle duration, and worse daytime episodic memory. In controls, poorer SDMC was associated with higher AHI. Impaired daytime memory consolidation, reduced hippocampal volumes, shorter sleep spindles, and greater sleep apnea severity are indicators of diminished SDMC in older adults and should be explored in future studies.

Recurrent delirium over 12 months predicts dementia: results of the Delirium and Cognitive Impact in Dementia (DECIDE) study

Background

Delirium is common, distressing and associated with poor outcomes. Previous studies investigating the impact of delirium on cognitive outcomes have been limited by incomplete ascertainment of baseline cognition or lack of prospective delirium assessments. This study quantified the association between delirium and cognitive function over time by prospectively ascertaining delirium in a cohort aged ≥ 65 years in whom baseline cognition had previously been established.

Methods

For 12 months, we assessed participants from the Cognitive Function and Ageing Study II-Newcastle for delirium daily during hospital admissions. At 1-year, we assessed cognitive decline and dementia in those with and without delirium. We evaluated the effect of delirium (including its duration and number of episodes) on cognitive function over time, independently of baseline cognition and illness severity.

Results

Eighty two of 205 participants recruited developed delirium in hospital (40%). One-year outcome data were available for 173 participants: 18 had a new dementia diagnosis, 38 had died. Delirium was associated with cognitive decline (−1.8 Mini-Mental State Examination points [95% CI –3.5 to –0.2]) and an increased risk of new dementia diagnosis at follow up (OR 8.8 [95% CI 1.9–41.4]). More than one episode and more days with delirium (>5 days) were associated with worse cognitive outcomes.

Conclusions

Delirium increases risk of future cognitive decline and dementia, independent of illness severity and baseline cognition, with more episodes associated with worse cognitive outcomes. Given that delirium has been shown to be preventable in some cases, we propose that delirium is a potentially modifiable risk factor for dementia.

Systematic review on the instruments used for measuring the association of the level of multimorbidity and clinically important outcomes

OBJECTIVES

There are multiple instruments for measuring multimorbidity. The main objective of this systematic review was to provide a list of instruments that are suitable for use in studies aiming to measure the association of a specific outcome with different levels of multimorbidity as the main independent variable in community-dwelling individuals. The secondary objective was to provide details of the requirements, strengths and limitations of these instruments, and the chosen outcomes.

METHODS

We conducted the review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PROSPERO registration number: CRD42018105297). We searched MEDLINE, Embase and CINAHL electronic databases published in English and manually searched the Journal of Comorbidity between 1 January 2010 and 23 October 2020 inclusive. Studies also had to select adult patients from primary care or general population and had at least one specified outcome variable. Two authors screened the titles, abstracts and full texts independently. Disagreements were resolved with a third author. The modified Newcastle-Ottawa Scale was used for quality assessment.

RESULTS

Ninety-six studies were identified, with 69 of them rated to have a low risk of bias. In total, 33 unique instruments were described. Disease Count and weighted indices like Charlson Comorbidity Index were commonly used. Other approaches included pharmaceutical-based instruments. Disease Count was the common instrument used for measuring all three essential core outcomes of multimorbidity research: mortality, mental health and quality of life. There was a rise in the development of novel weighted indices by using prognostic models. The data obtained for measuring multimorbidity were from sources including medical records, patient self-reports and large administrative databases.

CONCLUSIONS

We listed the details of 33 instruments for measuring the level of multimorbidity as a resource for investigators interested in the measurement of multimorbidity for its association with or prediction of a specific outcome.

Cognitive variability, brain aging, and cognitive decline in late-life major depression

OBJECTIVES

Older adults with late-life major depression (LLMD) are at increased risk of dementia. Dispersion, or within-person performance variability across cognitive tests, is a potential marker of cognitive decline. This study examined group differences in dispersion between LLMD and nondepressed healthy controls (HC) and investigated whether dispersion was a predictor of cognitive performance 1 year later in LLMD. We also explored demographic, clinical, and structural imaging correlates of dispersion in LLMD and HC. We hypothesized that dispersion would be greater in LLMD compared with HC and would be associated with worse cognitive performance 1 year later in LLMD.

DESIGN

Participants were enrolled in the Neurobiology of Late-Life Depression, a naturalistic longitudinal investigation of the predictors of poor illness course in LLMD.

PARTICIPANTS

The baseline sample consisted of 121 older adults with LLMD and 39 HC; of these subjects, 94 LLMD and 35 HC underwent magnetic resonance imaging (MRI). One-year cognitive data were available for 107 LLMD patients.

MEASUREMENTS

All participants underwent detailed clinical and structural MRI at baseline. LLMD participants also completed a comprehensive cognitive evaluation 1 year later.

RESULTS

Higher test dispersion was evident in LLMD when compared with nondepressed controls. Greater baseline dispersion predicted 1-year cognitive decline in LLMD patients even when controlling for baseline cognitive functioning and demographic and clinical confounders. Dispersion was correlated with white matter lesions in LLMD but not HC. Dispersion was also correlated with anxiety in both LLMD and HC.

CONCLUSIONS

Dispersion is a marker of neurocognitive integrity that requires further exploration in LLMD.

Safety and efficacy of preoperative chemoradiotherapy in fit older patients with intermediate or locally advanced rectal cancer evaluated by comprehensive geriatric assessment: A planned interim analysis of a multicenter, phase II trial

BACKGROUND AND PURPOSE

Comprehensive geriatric assessment (CGA) is a diagnostic method to assess the physical and mental health status of older patients. The purpose of this study was to assess the safety and efficacy of preoperative concurrent chemoradiotherapy (preCRT) for intermediate or locally advanced rectal cancer in older people who were classified as "fit" by CGA. The interim analysis focusing on safety was reported here as the first part of this trial.

METHODS AND MATERIALS

This is a single arm, multicenter, phase II trial. The eligible patients for this study were aged 70 years or above that fulfilled the standard of intermediate or locally advanced risk category, and met the standard of fit (SIOG1) evaluated by CGA. All patients received preCRT (50 Gy) with Raltitrexed (3 mg/m2 on d1 and d22). Qualitative and quantitative variables were described using descriptive statistics. The surgery adherence predicting was analyzed by multivariate logistic regression.

RESULTS

Thirty-nine fit patients were enrolled. All patients except one finished radiotherapy without dose reduction. Thirty-two patients finished the prescribed Raltitrexed therapy as scheduled. A serious toxicity was observed in 12 patients (30.8%), and only six patients (15.4%) experienced non-hematological side effects.

CONCLUSION

Overall, our results showed that preCRT was feasible and safe in older patients with rectal cancer who were evaluated as fit based on CGA, supporting the use of CGA to tailor oncological treatment and predict the tolerance of a specific therapy. Completing this trial as planned would provide further valuable insights.

Executive dysfunction and risk of suicide in older adults: a population-based prospective cohort study

OBJECTIVE

It is uncertain what factors increases the risk of suicide in older adults without depression, and it is unknown whether executive dysfunction (ED) is one of those factors. We aimed to examine the effect of ED on the risk of suicide in non-demented older adults without depression.

METHODS

In an ongoing population-based prospective cohort of Korean older adults, we identified suicide using the National Mortality Database and suicidal ideation or attempt (SIA) based on the Korean version of the Mini International Neuropsychiatric Interview. We defined ED as performing below -1.5 SD of age-adjusted, gender-adjusted and education-adjusted norms in any of following tests: Frontal Assessment Battery, Trail Making Test A, Digit Span Test or Verbal Fluency Test.

RESULTS

The mean age of the 4791 participants at baseline was 69.7 (SD 6.4) years, and 57.1% of them were women (mean follow-up duration=4.9 years). ED at baseline increased the risk of suicide by about seven times (HR 7.20, 95% CI 1.84 to 28.12, p=0.005) but did not change the risk of SIA. However, cognitive impairment without ED did not change the risks of suicide and SIA. In participants with ED, being aged 75 years or above, living alone, and having a low socioeconomic status were associated with the risk of suicide.

CONCLUSION

ED is a strong risk factor of late life suicide independent from depression, particularly in very old adults living in disadvantaged environments.

Altered heart rate variability during sleep in mild cognitive impairment

STUDY OBJECTIVES

Cardiovascular autonomic dysfunction, as measured by short-term diurnal heart rate variability (HRV), has been reported in older adults with mild cognitive impairment (MCI). However, it is unclear whether this impairment also exists during sleep in this group. We, therefore, compared overnight HRV during sleep in older adults with MCI and those with subjective cognitive impairment (SCI).

METHODS

Older adults (n = 210) underwent overnight polysomnography. Eligible participants were characterized as multi-domain MCI or SCI. The multi-domain MCI group was comprised of amnestic and non-amnestic subtypes. Power spectral analysis of HRV was conducted on the overnight electrocardiogram during non-rapid eye movement (NREM), rapid eye movement (REM), N1, N2, N3 sleep stages, and wake periods. High-frequency HRV (HF-HRV) was employed as the primary measure to estimate parasympathetic function.

RESULTS

The MCI group showed reduced HF-HRV during NREM sleep (p = 0.018), but not during wake or REM sleep (p > 0.05) compared to the SCI group. Participants with aMCI compared to SCI had the most pronounced reduction in HF-HRV across all NREM sleep stages-N1, N2, and N3, but not during wake or REM sleep. The naMCI sub-group did not show any significant differences in HF-HRV during any sleep stage compared to SCI.

CONCLUSIONS

Our study showed that amnestic MCI participants had greater reductions in HF-HRV during NREM sleep, relative to those with SCI, suggesting potential vulnerability to sleep-related parasympathetic dysfunction. HF-HRV, especially during NREM sleep, may be an early biomarker for dementia detection.

Efficiency of application of sorbed probiotics in complex therapy of pneumonia caused by SARS-CoV-2. Part 1. Heating clinical displays period

Aim. To determine the clinical efficacy and safety of the sorbed probiotics Bifidobacterium bifidum 1 (5108 KОЕ) and B. bifidum 1 (5107 KОЕ) in combination with Lactobacillus plantarum 8P-А3 in the complex therapy of pneumonia caused by SARS-CoV-2 in adult patients without severe risk factors. Materials and methods. An open, randomized prospective study included 100 patients (45 men, 55 women), aged 18 to 60 years without risk factors for severe COVID-19 with pneumonia confirmed by computed tomography, and an area of lung lesion no more than 75% (moderate forms). SARS-CoV-2 RNA in nasal and oropharyngeal swabs (RT-PCR) was detected in 72% of the participants, in the rest it was highly probable in terms of the aggregate parameters. Diagnostics of COVID-19 and its severity, the appointment of a standard examination and treatment were carried out in accordance with the Temporary Methodological Recommendations of the Ministry of Health of Russia, version 8 of 09.03.2020. This publication presents the results of using B. bifidum 1 (3 capsules twice a day for 10 days) during the peak of clinical manifestations (in a hospital). Results. In those who received sorbed B. bifidum 1, by the 10th day of treatment, the frequency of weakness was 32% lower (RR 0.55 [95% CI 0.240.73], OR 0.25 [0.110.59]); hypoosmia/dysgeusia by 22% (RR 0.42 [0.050.65], OR 0.40 [0.170.90]) and cough by 24% (RR 0.39 [0.070.60], OR 0.38 [0.170.84]). B. bifidum 1 reduced the average duration of weakness by 3 days [1.14.9], hypoosmia/dysgeusia by 3.2 days [1.35.1], cough by 1.9 days [0.43,4], dyspnea by 1.8 days [0.72.7], diarrhea by 1.7 days [0.13.5]; reduced the risk of antibiotic-associated diarrhea by 20% (RR 0.77 [0.240.93], OR 0.18 [0.050.68]). Due to the deterioration of the condition and the increase in the symptoms of respiratory failure, additional treatment was required less often by 24% (p=0.005). After the end of the intervention, the frequency of virologic debridement, levels of CRP, leukocytes, lymphocytes, platelets and the degree of lung damage on computed tomography did not statistically differ in the compared groups. No side effects of B. bifidum 1 (5108 KОЕ) have been identified. Conclusion. The use of sorbed B. bifidum 1 (5108 KОЕ) improved the well-being of patients without risk factors with moderate viral (SARS-CoV-2) pneumonia and reduced the duration of diarrheal syndrome in a short time. The safety profile of their use was high. More research is needed to clarify the anti-inflammatory effects of the sorbed probiotic.

Dual Sensory Impairment and Cognitive Impairment in the Korean Longitudinal Elderly Cohort

OBJECTIVE

To investigate the effects of single sensory impairment (SSI; visual or auditory) or dual sensory impairment (DSI; visual and auditory) on dementia and longitudinal changes of neuropsychological test scores.

METHODS

In this nationwide, prospective, community-based elderly cohort study, KLOSCAD (the Korean Longitudinal Study on Cognitive Aging and Dementia), 6,520 elderly individuals (58-101 years) representing the general population were included. We defined visual and auditory sensory impairment via self-report questionnaire: 932 had normal sensory function, 2,957 had an SSI, and 2,631 had a DSI. Demographic and clinical variables including cognitive outcomes were evaluated every 2 years over 6 years. Through logistic regression, Cox regression, and linear mixed model analysis, the relationship between SSI or DSI and dementia prevalence, dementia incidence, and change in neuropsychological scores were evaluated.

RESULTS

At baseline, DSI was significantly associated with increased dementia prevalence compared to normal sensory function (odds ratio [OR] 2.17, 95% confidence interval [CI] 1.17-4.02), but SSI was not (OR 1.27, 95% CI 0.66-2.41). During the 6-year follow-up, the incidence of dementia was significantly higher in the DSI group than in the normal sensory function group (hazard ratio 1.9, 95% CI 1.04-3.46) and neuropsychological scores significantly decreased (β -0.87, 95% CI [-1.17 to -0.58]).

CONCLUSIONS

Our results suggest that coexisting visual and hearing impairments facilitate dementia prevalence, dementia incidence, and cognitive decline, but visual or hearing impairment alone do not. Visual and hearing impairment may lead to dementia or cognitive decline independent of Alzheimer pathology.

Obesity and Oxidative Stress in Older Adults At Risk for Dementia: A Magnetic Resonance Spectroscopy Study

OBJECTIVE

This study aimed to investigate the relationship between obesity and oxidative stress in older adults at risk for dementia. It also aimed to explore the influence of physical activity on the relationship between obesity and oxidative stress in this at risk cohort.

METHODS

Older adults at risk for dementia underwent comprehensive medical, neuropsychological, and psychiatric assessment. At risk was defined as participants with subjective or mild cognitive impairment. Glutathione was assessed by magnetic resonance spectroscopy in the left hippocampus and the anterior and posterior cingulate cortex. Body mass index (BMI) was calculated and classified as healthy (BMI <25 kg/m2) or overweight/obese (BMI ≥25 kg/m2).

RESULTS

Sixty-five older adults (mean age=66.2 y) were included for analysis. The overweight/obese group had significantly greater glutathione in the hippocampus compared with the healthy weight group (t=-2.76, P=0.008). No significant difference in glutathione was observed between groups in the anterior or posterior cingulate. In the overweight/obese group, a higher BMI was associated with a diabetes diagnosis and lower total time engaging in physical activity (r=-0.36, P=0.025), however, glutathione did not correlate with activity levels across groups.

CONCLUSION

This study demonstrates that changes in in vivo markers of oxidative stress are present in overweight/obese older adults at risk for dementia. Future research should explore the relationship with diabetes and the longitudinal relationship between BMI and oxidative stress, and response to therapeutic interventions.

Impact of age, comorbidity, and treatment characteristics on survival in older women with advanced high grade epithelial ovarian cancer

OBJECTIVES

Older women have a worse prognosis with advanced epithelial ovarian cancer (EOC) and comorbidities likely contribute to poor outcomes. We sought to identify comorbid conditions and treatment-related factors in older women.

METHODS

A retrospective chart review identified 351 patients who underwent cytoreductive surgery (CRS). 100/351 (28.5%) were ≥ 70 years old. Demographic and clinicopathologic information was collected. Crude progression-free (PFS) and overall survival (OS) estimates were calculated using Kaplan-Meier method. Cox proportional hazards regression model was used to estimate hazard ratios and adjustments for confounders.

RESULTS

Study subjects ≥70 years old had significantly: higher Cumulative Illness Rating Scale-Geriatric (CIRS-G) score (5.9 vs 4.3; p = 0.0001), less completion of adjuvant chemotherapy (24% vs 15.1%; p = 0.049), less intraperitoneal (IP) therapy (18.2% vs 35.5%; p = 0.002), less clinical trial participation (16% vs 26.3%; p = 0.040), decreased platinum sensitivity (60% vs 73.7%; p = 0.012) and lacked BRCA mutations (0% vs 12%; p = 0.0006). They were less likely to have optimal CRS (75% vs 86.9%; p = 0.007) with same surgical complexity (p = 0.89). Patients ≥70 had significantly worse PFS and OS. In a multivariate analysis, better OS was associated with younger age (<70 years old), any IP therapy, completion of adjuvant chemotherapy, and platinum sensitivity.

CONCLUSION

The older cohort had worse CIRS-G scores (5.9 vs 4.3; p = 0.0001), but no strong associations between comorbidities and treatment characteristics, but less optimal CRS rates (75% vs 86.9%; p = 0.007) with similar surgical complexity and less platinum sensitivity. Our results show comorbid conditions in older patients with advanced EOC may have less impact than tumor biology.

Association between psychomotor disturbance and treatment outcome in psychotic depression: a STOP-PD II report

BACKGROUND

Little is known about the relationship between psychomotor disturbance (PMD) and treatment outcome of psychotic depression. This study examined the association between PMD and subsequent remission and relapse of treated psychotic depression.

METHODS

Two hundred and sixty-nine men and women aged 18-85 years with an episode of psychotic depression were treated with open-label sertraline plus olanzapine for up to 12 weeks. Participants who remained in remission or near-remission following an 8-week stabilization phase were eligible to participate in a 36-week randomized controlled trial (RCT) that compared the efficacy and tolerability of sertraline plus olanzapine (n = 64) with sertraline plus placebo (n = 62). PMD was measured with the psychiatrist-rated sign-based CORE at acute phase baseline and at RCT baseline. Spearman's correlations and logistic regression analyses were used to analyze the association between CORE total score at acute phase baseline and remission/near-remission and CORE total score at RCT baseline and relapse.

RESULTS

Higher CORE total score at acute phase baseline was associated with lower frequency of remission/near-remission. Higher CORE total score at RCT baseline was associated with higher frequency of relapse, in the RCT sample as a whole, as well as in each of the two randomized groups.

CONCLUSIONS

PMD is associated with poorer outcome of psychotic depression treated with sertraline plus olanzapine. Future research needs to examine the neurobiology of PMD in psychotic depression in relation to treatment outcome.

Comorbidities and frailty predict outcome of patients with myelodysplastic syndromes. Should we integrate them in novel prognostic scoring systems?

Prognosis of myelodysplastic syndromes (MDS) is based on scoring systems focusing on disease-related factors; however, several studies have shown that patient-related factors might be equally important in prognostication of patients with malignancies in general but also for patients with MDS. The aim of this review was to evaluate the role of comorbidities and frailty as prognostic factors as well as predictive factors of response and tolerability to hypomethylating agents. Both comorbidities and frailty were shown to be predictive of overall survival; however, they mostly correlate with risk for non-leukemic death rather than leukemia-free survival. In patients with higher-risk MDS, comorbidities burden and frailty might be predictive of poor treatment response as well as increased toxicity. In this context, all patients with MDS should be evaluated for comorbidities and frailty at baseline, preferentially using indices validated for MDS. This assessment should guide the selection of treatment. Decision regarding treatment initiation should be based on disease-related factors as captured by the established prognostic scoring systems.

VOTRAGE study: Phase I dose-escalation study of pazopanib in unfit older patients

BACKGROUND

Pazopanib is a tyrosine kinase inhibitor given at the approved dose of 800 mg orally once daily (OD), but often requiring individual dose adjustment due to toxicity. Limited data is available to guide prescription in older patients especially the unfit according to geriatric assessment.

PATIENTS AND METHODS

VOTRAGE is a 3 + 3 dose-escalation, open-label phase I trial of continuous OD oral administration of pazopanib to evaluate safety, PK and PD data in unfit older patients with advanced solid tumors. The primary objective was to determine the maximum tolerated dose (MTD). PK data were compared with those obtained in younger adult patients in a population PK analysis.

RESULTS

Eighteen patients with a median age of 82.5 years (range 75-91) were included in three dosing cohorts (400, 600, and 800 mg daily). Three dose-limiting toxicities (DLT) were observed in five patients at 800 mg and one DLT at 600 mg in six evaluable patients. MTD was defined as level 2 dose (600 mg). Individual oral clearance was not correlated with age. A relationship was observed between the occurrence of DLT and pazopanib plasma exposure. Decreased oral bioavailability of pazopanib when given with proton-pump inhibitors was confirmed in this group of patients.

CONCLUSION

We recommend performing geriatric assessment in patients older than 75 and starting pazopanib at 600 mg per day in unfit older patients. Therapeutic drug monitoring appears very helpful in this population.

Stratification and management of cardiovascular risk in cancer patients. A consensus document of the SEC, FEC, SEOM, SEOR, SEHH, SEMG, AEEMT, AEEC, and AECC

Both cancer treatment and survival have significantly improved, but these advances have highlighted the deleterious effects of vascular complications associated with anticancer therapy. This consensus document aims to provide a coordinated, multidisciplinary and practical approach to the stratification, monitoring and treatment of cardiovascular risk in cancer patients. The document is promoted by the Working Group on Cardio Oncology of the Spanish Society of Cardiology (SEC) and was drafted in collaboration with experts from distinct areas of expertise of the SEC and the Spanish Society of Hematology and Hemotherapy (SEHH), the Spanish Society of Medical Oncology (SEOM), the Spanish Society of Radiation Oncology (SEOR), the Spanish Society of General and Family Physicians (SEMG), the Spanish Association of Specialists in Occupational Medicine (AEEMT), the Spanish Association of Cardiovascular Nursing (AEEC), the Spanish Heart Foundation (FEC), and the Spanish Cancer Association (AECC).

A community-based nurse-led medication self-management intervention in the improvement of medication adherence in older patients with multimorbidity: protocol for a randomised controlled trial

Background

Older patients suffering from multimorbidity are at high risk of medication nonadherence. It has been well established that self-management support is an effective strategy to enhance medication adherence for patients with chronic conditions. However, little is known about the effect of the medication self-management intervention in older patients with multimorbidity. This paper presents the protocol for a study that aims to evaluate the effectiveness of a nurse-led medication self-management intervention in improving medication adherence and health outcomes for community-dwelling older patients with multimorbidity.

Methods

The study protocol follows the recommendations of the Standard Protocol Items: Recommendations for Interventional Trials 2013 statement. This study is a multicentre, single-blind, two-arm randomised controlled trial. Older patients with multimorbidity will be recruited from three community health centres in Changsha, China. A total of 136 participants will be randomly allocated to receive usual care or usual care plus the medication self-management intervention. The intervention will be delivered by community nurses. The 6-week intervention includes three face-to-face education sessions and two weekly follow-up phone calls. Participants in the control group continue to receive all respects of usual care offered by community healthcare providers, including chronic disease management, drug prescription, referral to hospital specialists, health education and consultations regarding patients’ diseases and treatments during centre visits. The primary outcome is medication adherence as measured by the 5-item Medication Adherence Report Scale. Secondary outcomes include medication self-management capacity (medication knowledge, medication beliefs, medication social support, medication skills, and medication self-efficacy), treatment experiences (medication treatment satisfaction and treatment burden), quality of life, and utilisation of healthcare services. All outcomes will be measured at baseline, immediately post-intervention, and at 3-month post-intervention.

Discussion

This study will provide evidence about the effectiveness of a medication self-management intervention, delivered by nurses, for older patients with multimorbidity and adherence problems. It is expected that the results of the study, if proven effective in improving patients’ adherence and health outcomes, will provide evidence-based self-management support strategies for healthcare providers in routine chronic disease management in community settings.

Cancer Bereavement and Depression Symptoms in Older Spouses: The Possible Modifying Role of the Circadian Rest-Activity Rhythm

OBJECTIVES

This study examines the associations of cancer death and aspects of the 24-h circadian rest-activity rhythm (RAR) on depression symptoms in older spouses.

METHODS

Participants included 46 adults aged 60-94 years (M = 73 years) who experienced the death of a spouse. We tested a multivariate model using cancer death (vs. non-cancer death) and RAR variables as correlates of depression symptoms while controlling for age, sex, physical illness burden, and preparedness for death. We also present a case example to describe the behavioral activity patterns of a participant bereaved by cancer.

RESULTS

Cancer death was associated with elevated levels of depression symptoms. However, the timing of the RAR moderated this association. Cancer bereavement was associated with depression symptoms when participants "settled-down" after 11:00 PM. The case example illustrates how intrusive thoughts about death quality impacts a widower's drive to stay busy with daily activities.

CONCLUSIONS

Settling down earlier in the evening is important for older spouses bereaved by cancer, in terms of fewer symptoms of depression.

CLINICAL IMPLICATIONS

Objectively specifying the activity patterns of older spouses bereaved by cancer is a promising avenue for interventions that aim to reduce depression symptoms.

Biological aspects of aging that influence response to anticancer treatments

PURPOSE OF REVIEW

Cancer is a disease of older adults, where fitness and frailty are a continuum. This aspect poses unique challenges to the management of cancer in this population. In this article, we review the biological aspects influencing the efficacy and safety of systemic anticancer treatments.

RECENT FINDINGS

The organ function decline associated with the ageing process affects multiple systems, including liver, kidney, bone marrow, heart, muscles and central nervous system. These can have a significant impact on the pharmacokinetics and pharmacodynamics of systemic anticancer agents. Comorbidities also represent a key aspect to consider in decision-making. Renal disease, liver conditions and cardiovascular risk factors are prevalent in this age group and may impact the risk of adverse outcomes in this setting.

SUMMARY

The systematic integration of geriatrics principles in the routine management of older adults with cancer is a unique opportunity to address the complexity of this population and is standard of care based on a wide range of benefits. This approach should be multidisciplinary and involve careful discussion with hospital pharmacists.

Potentially inappropriate medication (PIM) use and severe drug interactions (SDIs) in older adults with cancer

BACKGROUND

Older adults with cancer frequently have other co-morbidities requiring prescription pharmacotherapy. The objectives of this study were to identify the prevalence of potentially inappropriate medications (PIMs), severe drug interactions (SDIs) and associated risk factors in these patients.

MATERIALS AND METHODS

This twelve-month prospective observation study was conducted at an Irish Hospital. PIMs were identified in older adults (≥65 years) using STOPP and OncPal criteria; potential SDIs using Stockley's interaction checker.

RESULTS

We enrolled 186 patients; mean age 72.5(SD5.7) years, 46.2% female, mean co-morbidities 7.5(SD3.4), median medications 7(IQR4-9). Polypharmacy (≥6 medications) and major polypharmacy (≥11 medications) were identified in 60.8% and 17.7% respectively. STOPP PIMs were observed in 73.1%; median 2(IQR1-3). The most common PIM identified was any drug prescribed beyond the recommended duration (46.5%). For each additional prescription, the odds of receiving a STOPP PIM increased by 79.2% (OR 1.792, 95% CI 1.459-2.02). Potential SDIs were identified in 50.5% participants. The most common were beta-blocker/alpha-blocker (6.5%), selective-serotonin re-uptake inhibitor (SSRI)/proton pump inhibitor (PPI) (5.9%) and SSRI/Aspirin (4.8%). For each additional prescription, the odds of an SDI increased by 50.8% (OR 1.508, 95% CI 1.288-1.764). Seventy-seven (41.4%) participants died within six months of enrolment. OncPal PIMs were observed in 81.8% of this cohort, median 2(IQR1-3). The most common OncPal PIM was statin therapy (38%). For each additional prescription, the odds of receiving an OncPal PIM increased by 38.2%, (OR 1.382, 95% CI 1.080-1.767).

CONCLUSIONS

PIMs and SDIs are common in this population. Comprehensive specialist evaluation of medications by a geriatrician may identify PIMs thereby reducing related adverse outcomes such as SDIs.

Association between malnutrition and stages of sarcopenia in geriatric rehabilitation inpatients: RESORT

BACKGROUND & AIMS

Malnutrition and sarcopenia coexist in older adults, yet they remain largely undiagnosed and untreated, despite available interventions. This study aimed to assess the prevalence, the coexistence of, and the association between malnutrition and sarcopenia in geriatric rehabilitation inpatients.

METHODS

REStORing health of acutely unwell adulTs (RESORT) is an observational, longitudinal cohort of geriatric rehabilitation inpatients. The association between malnutrition, diagnosed according to the Global Leadership Initiative on Malnutrition (GLIM) criteria and sarcopenia according to the revised definition of the European Working Group on Sarcopenia in Older People (EWGSOP2) (no sarcopenia, probable sarcopenia, confirmed sarcopenia and severe sarcopenia) was determined using multinomial logistic regression analyses, adjusted for age, sex, comorbidities and cognitive impairment.

RESULTS

Out of 506 geriatric rehabilitation inpatients, 51% were malnourished, 49% had probable sarcopenia, 0.4% had confirmed sarcopenia (non-severe) and 19% had severe sarcopenia. Malnutrition and probable sarcopenia and malnutrition and confirmed/severe sarcopenia coexisted in 23% and 13% of the 506 patients respectively. Malnutrition was not associated with probable sarcopenia (OR = 0.91, 95% CI = 0.58-1.42, p = 0.674) but with severe sarcopenia (OR = 2.07, 95% CI = 1.13-3.81, p = 0.019).

CONCLUSION

The prevalence, coexistence of, and the association between malnutrition and severe sarcopenia in geriatric rehabilitation inpatients warrant diagnosis at admission. Further research into feasible and effective interventions to counteract both conditions to improve geriatric rehabilitation outcomes is needed.
