Association between nutritional status (MNA®-SF) and frailty (SHARE-FI) in acute hospitalised elderly patients

Monitoring Gait and Physical Activity of Elderly Frail Individuals in Free-Living Environment: A Feasibility Study

INTRODUCTION

Frailty is conventionally diagnosed using clinical tests and self-reported assessments. However, digital health technologies (DHTs), such as wearable accelerometers, can capture physical activity and gait during daily life, enabling more objective assessments. In this study, we assess the feasibility of deploying DHTs in community-dwelling older individuals, and investigate the relationship between digital measurements of physical activity and gait in naturalistic environments and participants' frailty status, as measured by conventional assessments.

METHODS

Fried Frailty Score (FFS) was used to classify fifty healthy individuals as non-frail (FFS = 0, n/female = 21/11, mean ± SD age: 71.10 ± 3.59 years), pre-frail (FFS = 1-2, n/female = 23/9, age: 73.74 ± 5.52 years), or frail (FFS = 3+, n/female = 6/6, age: 70.70 ± 6.53 years). Participants wore wrist-worn and lumbar-worn GENEActiv accelerometers (Activinsights Ltd., Kimbolton, UK) during three in-laboratory visits, and at-home for 2 weeks, to measure physical activity and gait. After this period, they completed a comfort and usability questionnaire. Compliant days at-home were defined as follows: those with ≥18 h of wear time, for the wrist-worn accelerometer, and those with ≥1 detected walking bout, for the lumbar-worn accelerometer. For each at-home measurement, a group analysis was performed using a linear regression model followed by ANOVA, to investigate the effect of frailty on physical activity and gait. Correlation between at-home digital measurements and conventional in-laboratory assessments was also investigated.

RESULTS

Participants were highly compliant in wearing the accelerometers, as 94% indicated willingness to wear the wrist device, and 66% the lumbar device, for at least 1 week. Time spent in sedentary activity and time spent in moderate activity as measured from the wrist device, as well as average gait speed and its 95th percentile from the lumbar device were significantly different between frailty groups. Moderate correlations between digital measurements and self-reported physical activity were found.

CONCLUSIONS

This work highlights the feasibility of deploying DHTs in studies involving older individuals. The potential of digital measurements in distinguishing frailty phenotypes, while unobtrusively collecting unbiased data, thus minimizing participants' travels to sites, will be further assessed in a follow-up study.

Malnutrition risk and frailty in head and neck cancer patients: coexistent but distinct conditions

PURPOSE

Both malnutrition and frailty are associated with adverse treatment outcomes. Malnutrition (risk) and frailty are each commonly present in patients with head and neck cancer (HNC). However, their coexistence and association is unknown. Main goal of this study is to determine the coexistence of, and the association between malnutrition risk and frailty in patients with HNC.

METHODS

In this retrospective analysis on prospectively collected data, newly diagnosed patients with HNC, enrolled in the OncoLifeS databiobank were included. The Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) was used to assess malnutrition risk. The Groningen Frailty Indicator (GFI) was used to assess frailty status. Multivariate logistic regression analyses were performed, taking into account several patient- and tumor-related factors.

RESULTS

In total, 197 patients were included. Seventy-six patients (39%) had a medium or high malnutrition risk and 71 patients (36%) were frail. In 38 patients (19%), malnutrition risk coexisted with frailty. Patients with medium and high malnutrition risk were, respectively, 4.0 (95% CI 1.5-11.2) and 13.4 (95% CI 4.0-48.7) times more likely to be frail, compared to patients with low malnutrition risk. In turn, frail patients were 6.4 times (95% CI 2.6-14.9) more likely to have malnutrition risk compared to non-frail patients.

CONCLUSIONS

Malnutrition risk and frailty frequently coexist but not fully overlap in newly diagnosed patients with HNC. Therefore, screening for both conditions is recommended.

Evaluation of Nutritional Status in an Acute Geriatric Unit: Retrospective Study and Analysis of Frailty Syndrome

INTRODUCTION

The aim of our study is to evaluate the nutritional status of patients in an acute geriatric unit.

METHODS

Patients included in the study were hospitalized in an acute geriatric unit over a period of 6 months. The nutritional status of each patient was evaluated with anthropometric measurements (the BMI and MNA scales), and biological measurements (albumin). Frailty was evaluated using three scales: the Fried scale, the CFS and the modified SEGA scale.

RESULTS

A total of 359 patients were included, comprising 251 women (70%) with an average age of 85.28 years. The study showed that 102 elderly subjects were considered undernourished according to the BMI scale, 52 subjects were undernourished according to the MNA scale, and 50 subjects were undernourished according to their albumin levels. The relationships between undernutrition and frailty syndrome studied in our work show that elderly subjects who are undernourished according to the BMI and MNA scales are significantly frail according to Fried and Rockwood, whereas those who are undernourished according to their albumin levels are significantly frail according to Fried and the modified SEGA scale.

CONCLUSION

The relationship between undernutrition and the frailty syndrome is close, and their joint screening is necessary, whether on an outpatient or in-hospital basis, in order to prevent negative events related to comorbidities and geriatric syndromes.

The prognostic value of comprehensive geriatric assessment on the management of older patients with small cell lung cancer

BACKGROUND/AIMS

The prognostic value of a comprehensive geriatric assessment (CGA) for the management of older small cell lung cancer (SCLC) patients remains to be established.

METHODS

A retrospective cohort enrolled 21 SCLC patients over 65 years from March 2018 to 2019 at the Yonsei Cancer Center. The CGA included the following instruments: frailty, body mass index, sarcopenia (circumference of arm and calf, Timed Up and Go test, grip strength), comorbidity, polypharmacy, activities of daily living (ADL), Instrumental ADL, nutrition, depression, and cognitive function. The correlations of oncological and geriatric variables with overall survival (OS) were determined. The log-rank test with Cox model and Kaplan-Meier method were used for the analysis.

RESULTS

The median age was 75 years (range, 67 to 85). All patients had the Eastern Cooperative Oncology Group performance status 0-2. The median survival was 9.93 months (range, 1.53 to 36.30). Among CGA parameters, ADL and nutritional status had significant differences in OS in univariate analysis. In multivariate analysis, only nutritional status was independently associated with survival (hazard ratio, 0.17; 95% confidence interval, 0.05 to 0.57). Median OS for low nutritional status was 5.63 months and the normal nutrition group was 15.5 months (p = 0.004).

CONCLUSION

Pre-treatment nutritional status measured by CGA appears to be a predictor of OS in older SCLC patients. However, for further generalization of the implication of CGA in SCLC, a larger scale study with prospective design is strongly needed.

The prevalence of frailty and pre-frailty among geriatric hospital inpatients and its association with economic prosperity and healthcare expenditure: A systematic review and meta-analysis of 467,779 geriatric hospital inpatients

BACKGROUND

Frailty is a common and clinically significant condition among geriatric populations. Although well-evidenced pooled estimates of the prevalence of frailty exist within various settings and populations, presently there are none assessing the overall prevalence of frailty among geriatric hospital inpatients. The purpose of this review was to systematically search and analyse the prevalence of frailty among geriatric hospital inpatients within the literature and examine its associations with national economic indicators.

METHODS

Systematic searches were conducted on Ovid, Web of Science, Scopus, CINAHL Plus, and the Cochrane Library, encompassing all literature published prior to 22 November 2018, supplemented with manual reference searches. Included studies utilised a validated operational definition of frailty, reported the prevalence of frailty, had a minimum age ≥ 65 years, attempted to assess the whole ward/clinical population, and occurred among hospital inpatients. Two reviewers independently extracted data and assessed study quality.

RESULTS

Ninety-six studies with a pooled sample of 467,779 geriatric hospital inpatients were included. The median critical appraisal score was 8/9 (range 7-9). The pooled prevalence of frailty, and pre-frailty, among geriatric hospital inpatients was 47.4% (95% CI 43.7-51.1%), and 25.8% (95% CI 22.0-29.6%), respectively. Significant differences were observed in the prevalence of frailty stratified by age, prevalent morbidity, ward type, clinical population, and operational definition. No significant differences were observed in stratified analyses by sex or continent, or significant associations between the prevalence of frailty and economic indicators.

CONCLUSIONS

Frailty is highly prevalent among geriatric hospital inpatients. High heterogeneity exists within this setting based on various clinical and demographic characteristics. Pooled estimates reported in this review place the prevalence of frailty among geriatric hospital inpatients between that reported for community-dwelling older adults and older adults in nursing homes, outlining an increase in the relative prevalence of frailty with progression through the healthcare system.

What Does Joy in Living Mean to Elderly Residents of Nursing Homes in Singapore?

The rapid ageing of Singapore’s population has led to the phenomenon of more elderly spending more total years in nursing homes. This study aimed to explore the meaning of Joy in Living to elderly residents of nursing homes in Singapore, the enabling and disenabling conditions to Joy in Living in nursing homes and how Person-centered Care can support Joy in Living in nursing homes. The concept of Joy in Living is used in this study as it is unique to an individual elderly’s experience; The study employed hermeneutical phenomenological research methodology to allow for the exploration of Joy in Living in lived experiences of elderly residents through in-depth sixteen semi-structured interviews with elderly residents and six participant observations of three nursing homes (pre and post interviews) between July 2021 and November 2021; Seven themes for Joy in Living experiences to flourish were identified, including “supportive nursing home environment and practices”, “connectedness through meaningful relationships”, “meaningful daily living”, “fulfil the need for spiritual care”, “personal control”, “desire to be free from worries”, and “adapting to changes”, each of which explains a facet of Joy in Living experiences of the elderly residing in nursing homes. These themes include the enabling and disenabling conditions to Joy in Living in nursing homes; Focusing efforts and resources on enabling the seven themes, including fulfilling the need for spiritual care will allow Joy in Living experiences of elderly to flourish in nursing homes. This in turn promotes better psychosocial well-being of the elderly and better living environments where nursing home residents may enjoy satisfactory accommodation while spending their remaining years in joy.

Prevalence of Undernutrition, Frailty and Sarcopenia in Community-Dwelling People Aged 50 Years and Above: Systematic Review and Meta-Analysis

The world’s population aged ≥65 is expected to rise from one in eleven in 2019 to one in six by 2050. People aged ≥65 are at a risk of undernutrition, frailty, and sarcopenia. The association between these conditions is investigated in a hospital setting. However, there is little understanding about the overlap and adverse health outcomes of these conditions in community-dwelling people. This systematic review aims to quantify the reported prevalence and incidence of undernutrition, frailty, and sarcopenia among older people aged ≥50 living in community dwellings. Searches were conducted using six databases (AMED, CENTRAL, EMBASE, Web of Science, MEDLINE, and CINAHL), and 37 studies were included. Meta-analyses produced weighted combined estimates of prevalence for each condition (Metaprop, Stata V16/MP). The combined undernutrition prevalence was 17% (95% CI 0.01, 0.46, studies n = 5; participants = 4214), frailty was 13% (95% CI 0.11, 0.17 studies n = 28; participants = 95,036), and sarcopenia was 14% (95% CI 0.09, 0.20, studies n = 9; participants = 7656). Four studies reported incidence rates, of which three included data on frailty. Nearly one in five of those aged ≥50 was considered either undernourished, frail, or sarcopenic, with a higher occurrence in women, which may reflect a longer life expectancy generally observed in females. Few studies measured incidence rates. Further work is required to understand population characteristics with these conditions and the overlap between them. PROSPERO registration No. CRD42019153806.

Exploring Early Detection of Frailty Syndrome in Older Adults: Evaluation of Oxi-Immune Markers, Clinical Parameters and Modifiable Risk Factors

Ageing is accompanied with a decline in several physiological systems. Frailty is an age-related syndrome correlated to the loss of homeostasis and increased vulnerability to stressors, which is associated with increase in the risk of disability, comorbidity, hospitalisation, and death in older adults. The aim of this study was to understand the relationship between frailty syndrome, immune activation, and oxidative stress. Serum concentrations of vitamins A and E were also evaluated, as well as inflammatory biomarkers (CRP and IL-6) and oxidative DNA levels. A group of Portuguese older adults (≥65 years old) was engaged in this study and classified according to Fried’s frailty phenotype. Significant increases in the inflammatory mediators (CRP and IL-6), neopterin levels, kynurenine to tryptophan ratio (Kyn/Trp), and phenylalanine to tyrosine ratio (Phe/Tyr), and significant decreases in Trp and Tyr concentrations were observed in the presence of frailty. IL-6, neopterin, and Kyn/Trp showed potential as predictable biomarkers of frailty syndrome. Several clinical parameters such as nutrition, dependency scales, and polypharmacy were related to frailty and, consequently, may influence the associations observed. Results obtained show a progressive immune activation and production of pro-inflammatory molecules in the presence of frailty, agreeing with the inflammageing model. Future research should include different dimensions of frailty, including psychological, social, biological, and environmental factors.

Nutritional status and physical performance using handgrip and SPPB tests in hospitalized older adults

BACKGROUND & AIMS

Malnutrition and poor physical performance are highly prevalent within hospitalized older adults, and both have in common the loss of muscle mass. Likewise, there is growing interest in identifying markers of physical performance, other than just measuring muscle mass, that might be useful for managing malnutrition. This study aimed to (i) characterize the physical condition of hospitalized older adults in comparison to previously published reference percentile values of same age adults and (ii) to examine the association between the nutritional status and physical performance of older inpatients.

METHODS

A total of 604 inpatients (age 84.3 ± 6.8 years, 50.3% women) participated in this cross-sectional study. Patients were assessed for nutritional status (Mini Nutritional Assessment-Short Form (MNA-SF)) and physical performance (handgrip strength and the Short Physical Performance Battery (SPPB)).

RESULTS

During hospitalization, 65.7% of the inpatients were at risk of malnutrition or malnourished. More than a half of the older inpatients were unfit (≤P25) for handgrip strength (52.0%) and SPPB total score (86.3%) as well as for two of its subtests, gait speed (86.7%) and 5 times sit-to-stand (91.1%) tests. Patients' nutritional status was significantly associated with better physical performance within all tests (all p < 0.001), as their nutritional status improved so did their physical performance (all p for trend <0.001). Hence, being at risk of malnutrition or malnourished significantly increased the likelihood for being classified as unfit according to handgrip strength (OR: 1.466, 95% CI: 1.045-2.056), SPPB total score (OR: 2.553, 95% CI: 1.592-4.094) and 4-m walking test (OR: 4.049, 95% CI: 2.469-6.640) (all p < 0.05), and as frail (OR: 4.675, 95% CI: 2.812-7.772) according to the SPPB frailty threshold (p < 0.001).

CONCLUSIONS

This study reinforces the use of handgrip strength and SPPB, as well as its subtests (gait speed and 5 times sit-to-stand tests), in hospitalized older adults as alternative measures of muscle mass for malnutrition management. Hence, it seems that risk of malnutrition or malnutrition assessed by MNA-SF might help to predict poor physical performance in older inpatients.

Preoperative Nutritional Status in Elderly Inpatients with Gastrointestinal Cancer and Its Linear Association with Frailty

The identification and management of malnutrition is increasingly considered as an important issue in cancer treatment. This study aimed at determining the prevalence of malnutrition among elderly inpatients with gastrointestinal cancer. Meanwhile, the exact relationship between nutrition and frailty was explored. The presence of malnutrition was determined using Mini-Nutritional Assessment Short Form (MNA-SF), Nutrition Risk Screening 2002 (NRS2002), and a batch of laboratory parameters. A cross-sectional study of 265 eligible elderly inpatients with gastrointestinal cancer was conducted. The results showed that the prevalence of malnutrition classified by MNA-SF, NRS2002, albumin, prealbumin, total protein, hemoglobin, and total lymphocyte count were 66.8%, 68.7%, 41.5%, 27.9%, 39.2%, 40.8%, and 15.5%, respectively. There was a fair agreement between MNA-SF and NRS2002 (Kappa = 0.335, P < 0.001) in screening malnutrition. According to the albumin criterion, both MNA-SF and NRS2002 exhibited better sensitivity (72.7% and 76.4%, respectively) but poor specificity (37.4% and 36.8%, respectively) in screening malnutrition. A significant linear correlation between MNA-SF (NRS2002) and frailty was discovered (β=-0.259 and β = 0.412, respectively, P < 0.001). By identifying malnutrition in this elderly population, targeted plans can be developed as a part of cancer treatment and care. A better nutritional screening tool with both high sensitivity and specificity should be selected or developed.

Association Between Geriatric Nutritional Risk Index and Frailty in Older Hospitalized Patients

Objective

Previous studies have explored the association between malnutrition and frailty, but no study has investigated whether the Geriatric Nutritional Risk Index (GNRI), a simple and objective nutritional risk screening tool, is associated with the frailty of older adults. The study aimed to examine the relationship between nutrition-related risk, as assessed by the GNRI, and frailty among older hospitalized patients.

Methods

A cross-sectional study was conducted in the West China Hospital of Sichuan University with 740 patients aged ≥70 years between March 2016 and Jan 2017. Nutritional and frailty status was evaluated with the GNRI and FRAIL scale, respectively. The adjusted and unadjusted ordinal logistic regression analyses were used to examine the relationship between nutritional risk and frailty. The ability of GNRI in detecting frailty was assessed by receiver operating characteristic (ROC) curve analysis.

Results

The prevalence of low, moderate, and severe nutritional risk among frail patients were 30.1%, 27.6%, and 12.5%, respectively. Ordinal logistic regression analysis showed that malnutrition assessed by the GNRI had a significant association with frailty after adjustment of age, sex, polypharmacy, comorbidity, vision impairment, hearing impairment, cognitive impairment, and depression. In the ROC analysis, the area under the curve for GNRI identifying frailty was 0.698 (95% CI: 0.66-0.74; P<0.001), and the optimal cut-point value was 97.16 (sensitivity: 64.3%; specificity: 66.9%).

Conclusion

Nutrition-related risk screened by the GNRI was independently associated with frailty. The GNRI could be used as a simple tool in detecting nutritional risk and frailty status of older patients.

Prevalence of frailty and pain in hospitalised adult patients in an acute hospital: a protocol for a point prevalence observational study

INTRODUCTION

Frailty and pain are associated with adverse patient clinical outcomes and healthcare system costs. Frailty and pain can interact, such that symptoms of frailty can make pain assessment difficult and pain can exacerbate the progression of frailty. The prevalence of frailty and pain and their concurrence in hospital settings are not well understood, and patients with cognitive impairment are often excluded from pain prevalence studies due to difficulties assessing their pain. The aim of this study is to determine the prevalence of frailty and pain in adult inpatients, including those with cognitive impairment, in an acute care private metropolitan hospital in Western Australia.

METHODS AND ANALYSIS

A prospective, observational, single-day point prevalence, cross-sectional study of frailty and pain intensity of all inpatients (excluding day surgery and critical care units) will be undertaken. Frailty will be assessed using the modified Reported Edmonton Frail Scale. Current pain intensity will be assessed using the PainChek smart-device application enabling pain assessment in people unable to report pain due to cognitive impairment. Participants will also provide a numerical rating of the intensity of current pain and the worst pain experienced in the previous 24 hours. Demographic and clinical information will be collected from patient files. The overall response rate of the survey will be reported, as well as the percentage prevalence of frailty and of pain in the sample (separately for PainChek scores and numerical ratings). Additional statistical modelling will be conducted comparing frailty scores with pain scores, adjusting for covariates including age, gender, ward type and reason for admission.

ETHICS AND DISSEMINATION

Ethical approval has been granted by Ramsay Health Care Human Research Ethics Committee WA/SA (reference: 2038) and Edith Cowan University Human Research Ethics Committee (reference: 2020-02008-SAUNDERS). Findings will be widely disseminated through conference presentations, peer-reviewed publications and social media.

Clinical Frailty Scale and Biomarkers for Assessing Frailty in Elder Inpatients in China

OBJECTIVE

This study aimed to assess the feasibility of the Clinical Frailty Scale (CFS) and clinical biomarkers in assessing the frailty in elder inpatients in China.

DESIGN

The study was a cross-sectional study.

SETTING AND PARTICIPANTS

The study included 642 elder inpatients (295 females and 347 males) aged ≥65 years, from the Department of Geriatrics of Zhejiang Hospital between January 2018 and December 2019.

MEASUREMENTS

All participants underwent a comprehensive geriatric assessment and blood tests. Univariate and multivariate logistic regression was used to analyze the association between risk factors and frailty.

RESULTS

The average age of the participants was 82.72±8.06 years (range: 65-95 years) and the prevalence of frailty was 39.1% according to the CFS. Frail participants showed significantly lower short physical performance battery (SPPB), basic activities of daily living (ADL) and instrumental activities of daily living (IADL) scores (all p<0.001), and lower hemoglobin, total protein and albumin levels (all P<0.05) than nonfrail participants. Frail participants had higher CRP, D-dimer and fibrinogen levels than nonfrail participants (all p<0.05). Univariate logistic regression analysis showed a significant association between frailty and age, comorbidity, polypharmacy, fall history, SPPB, ADL, and IADL scores, D-dimer, fibrinogen, hemoglobin, total protein and albumin levels (all P<0.05). Multivariate logistic regression analysis indicated that age (odds ratio (OR), 95% confidence interval (CI)= 1.151(1.042-1.272), P=0.006), SPPB scores (OR, 95% CI=0.901(0.601-1.350), P<0.001), and D-dimer (OR, 95% CI=4.857(2.182-6.983), P<0.001), fibrinogen (OR, 95% CI=2.665(0.977-4.254), P<0.001), hemoglobin (OR, 95% CI=0.837(0.725-0.963), P= 0.044), and albumin (OR, 95% CI=0.860 (0.776-1.188), P<0.001) levels were independently associated with frailty in all participants.

CONCLUSION

Frailty in elder inpatients in China is characterized by older age, a lower SPPB scores, higher D-dimer and fibrinogen levels and lower hemoglobin and albumin levels. Functional decline and malnutrition may be the targets of frailty interventions.

Impact of Nutritional Status on Muscle Architecture in Elerly Patients Hospitalized in Internal Medicine Wards

Nutritional alterations are highly prevalent in older rather than adult hospitalized patients. In these subjects, a loss of physical performance is dependent on the impairment of muscle architecture. This study aimed to investigate the association between the nutritional status and muscle architecture in elderly patients hospitalized in internal medicine wards. 68 aged patients admitted in internal medicine wards were consecutively enrolled and stratified in three groups based on the Mini Nutritional Assessment (MNA) score: well-fed (WF), at risk of malnutrition (RM), and malnourished (M). Biochemical indices and anthropometric parameters were sampled at hospital admission. Furthermore, all patients were assessed at admission and after 7 days of hospitalization for muscle strength (hand-grip test), mass (bioimpedentiometry), and architecture (ultrasonography of vastus lateralis). At hospital admission, M patients showed lower percentage of fat free mass and muscle mass with respect to WF and RM. Furthermore, M group presented with lower muscle thickness and pennation angle, as compared to WF and RM. At admission, the MNA score was positively related to the pennation angle and muscle strength. Multivariate linear regression analysis showed that the nutritional status at admission was the only significant factor influencing pennation angle. Finally, during the first 7 days of hospitalization, a decrease of pennation angle occurred in all the groups studied. We conclude that malnutrition at admission is associated with impaired muscle architecture in elderly patients hospitalized in internal medicine wards. Moreover, muscle architecture is impacted by early hospitalization, irrespective of nutritional status.

The accumulation of deficits approach to describe frailty

The advancing age of the participants of the European Prospective Investigation into Cancer and Nutrition (EPIC)-Potsdam study was the incentive to investigate frailty as a major parameter of ageing. The aim of this study was to develop a multidimensional tool to measure frailty in an ageing, free-living study population. The "accumulation of deficits approach" was used to develop a frailty index (FI) to characterize a sub-sample (N = 815) of the EPIC-Potsdam (EPIC-P) study population regarding the aging phenomenon. The EPIC-P frailty index (EPIC-P-FI) included 32 variables from the following domains: health, physical ability, psychosocial and physiological aspects. P-values were calculated for the linear trend between sociodemographic and life style variables and the EPIC-P-FI was calculated using regression analysis adjusted for age. The relationship between the EPIC-P-FI and age was investigated using fractional polynomials. Some characteristics such as age, education, time spent watching TV, cycling and a biomarker of inflammation (C-reactive protein) were associated with frailty in men and women. Interestingly, living alone, having no partner and smoking status were only associated with frailty in men, and alcohol use and physical fitness (VO2max) only in women. The generated, multidimensional FI, adapted to the EPIC-P study, showed that this cohort is a valuable source for further exploration of factors that promote healthy ageing.

Predictability of a modified Mini- Nutritional- Assessment version on six-month and one-year mortality in hospitalized geriatric patients: a comparative analysis

Recently we introduced a modified Mini Nutritional Assessment (MNA) Short Form (MNA-SF) and Long Form (MNA-SF) with operationalization of the ‘mobility’ and ‘neuropsychological problems’ items of the MNA using scores on Barthel Index mobility item and Mini Mental State Examination and Geriatric Depression Scale scores. We have now evaluated the abilities of this modified MNA-SF and MNA-LF to predict mortality in comparison with the standard MNA-SF and MNA-LF and the Nutritional Risk Screening 2002 (NRS 2002) and the Malnutrition Universal Screening Tool (MUST). A prospective analysis was performed in 240 hospitalised geriatric patients aged ≥ 65 years. Malnutrition and/or malnutrition risk were assessed using the modified MNA-SF and MNA-LF, the standard MNA-SF and MNA-LF, and the NRS 2002 and MUST. The modified MNA-SF and MNA-LF and the standard MNA-SF and MNA-LF assessments (all p < 0.05), but not NRS 2002 or MUST (all p ≥ 0.05), predicted six-month and/or one-year mortality. Prediction of six-month and/or one-year mortality by the modified MNA-SF was comparable with predictions by the standard MNA-SF and MNA-LF (all p ≥ 0.05). The modified MNA-LF showed better prediction of six-month and one-year mortality than the standard MNA-SF and MNA-LF (all p < 0.05). The modified MNA-LF (all adjusted p < 0.05), but none of the other instruments (all adjusted p ≥ 0.05), predicted six-month and one-year mortality independently of age, sex, frailty, comorbidity and ADL disability burden. The modified MNA-SF and MNA-LF emerged as potentially valuable tools for predicting mortality in patients hospitalised on geriatric wards.

Prevalence and overlap of sarcopenia, frailty, cachexia and malnutrition in older medical inpatients

Background

Sarcopenia, frailty, cachexia and malnutrition are widespread syndromes in older people, characterized by loss of body tissue and related to poor outcome. The aim of the present cross-sectional study was to assess the prevalence of these syndromes and their overlap in older medical inpatients.

Methods

Patients aged 70 years or older who had been admitted to the internal medical department of a German university hospital were recruited. Sarcopenia, frailty, cachexia and malnutrition were assessed in a standardized manner according to current consensus definitions. Prevalence rates of these syndromes and their constituents and the concurrent occurrence of the syndromes (overlap) were calculated.

Results

One hundred patients (48 female) aged 76.5 ± 4.7 years with a BMI of 27.6 ± 5.5 kg/m² were included. The main diagnoses were gastroenterological (33%) and oncological diseases (31%). Sarcopenia was present in 42%, frailty in 33%, cachexia in 32% and malnutrition in 15% of the patients. 63% had at least one syndrome: 32% one, 11% two, 12% three and 8% all four. All four syndromes are characterized by significant weight loss during the last 12 months, which was most pronounced in malnourished patients and least pronounced in frail patients, and by significantly reduced physical performance. All syndromes were significantly pairwise related, except malnutrition and frailty. In 19% of patients sarcopenia and frailty occurred concurrently, in 20% frailty and cachexia and in 22% sarcopenia and cachexia with or without additional other syndromes. All malnourished patients except one were also cachectic (93%) and 80% of malnourished patients were also sarcopenic. 53% of malnourished patients were in addition frail, and these patients were affected by all four syndromes.

Conclusions

Nearly two thirds of older medical inpatients had at least one of the tissue loss syndromes sarcopenia, frailty, cachexia and malnutrition. The syndromes overlapped partly and were interrelated. Future studies with larger patient groups and longitudinal design are required to clarify the significance of single and concurrent occurrence of these syndromes for clinical outcome and successful therapy.

Changes of a frailty index based on common blood and urine tests during a hospital stay on geriatric wards predict 6-month and 1-year mortality in older people

Background

We aimed to evaluate the abilities of a 21-item frailty index based on laboratory blood and urine tests (FI-Lab21) assessed at different points in time, ie, at admission to hospital (FI-Lab21_admission) and before discharge from hospital (FI-Lab21_discharge), and the change of the FI-Lab21 during the hospital stay to predict 6-month and 1-year mortality in hospitalized geriatric patients.

Methods

Five hundred hospitalized geriatric patients aged ≥65 years were included in this analysis. Follow-up data were acquired after a period of 6 months and 1 year.

Results

The FI-Lab21_admission and FI-Lab21_discharge scores were 0.33±0.15 and 0.31±0.14, respectively (P<0.001). The FI-Lab21_admission and FI-Lab21_discharge both predicted 6-month and 1-year mortality (areas under the receiver operating characteristic curves: 0.72, 0.72, 0.77, and 0.75, respectively, all P<0.001). The predictive abilities for 6-month and 1-year mortality of the FI-Lab21_admission were inferior compared with those of the FI-Lab21_discharge (all P<0.05). Patients with a reduction in or stable FI-Lab21 score during the hospital stay revealed lower 6-month and 1-year mortality rates compared with the persons whose FI-Lab21 score increased during the hospital stay (all P<0.05). After adjustment for age, sex, and FI-Lab21_admission, each 1% decrease in the FI-Lab21 during the hospital stay was associated with a decrease in 6-month and 1-year mortality of 5.9% and 5.3% (both P<0.001), respectively.

Conclusion

The FI-Lab21 assessed at admission or discharge and the changes of the FI-Lab21 during the hospital stay emerged as interesting and feasible approaches to stratify mortality risk in hospitalized geriatric patients.

Lower Extremity Function Is Independently Associated With Hospitalization Burden in Heart Failure With Preserved Ejection Fraction

BACKGROUND

Frailty reflects decreased resilience to physiological stressors; its prevalence and prognosis are not fully defined in heart failure with preserved ejection fraction (HFpEF).

METHODS

The Short Physical Performance Battery (SPPB) was prospectively obtained in 114 outpatients with HFpEF. The SPPB tests gait speed, tandem balance, and timed chair rises, each scored from 0 to 4 points. Severe and mild frailty were respectively defined as an SPPB score ≤6 and 7-9 points. We used risk-adjusted logistic, Poisson, and negative binominal regression, respectively, to assess the relationship between SPPB score and risk of death or all-cause hospitalization, number of hospitalizations, and days hospitalized or dead longer than 6 months.

RESULTS

Patients were similar to other HFpEF cohorts (age 68 ± 13 years, 58% female, body mass index 36 ± 8 kg/m2, multiple comorbidities). Mean SPPB score was 6.9 ± 3.2, and 80% of patients were at least mildly frail. Over a 6-month period, the SPPB score independently predicted death or all-cause hospitalization (odds ratio 0.81 per point, 95% confidence interval [CI] 0.69-0.94, P = .006), number of hospitalizations (incidence rate ratio 0.92 per point, 95% CI 0.86-0.97, P = .006), and days hospitalized or dead (incidence rate ratio 0.85 per point, 95% CI 0.73-0.99, P = .04).

CONCLUSIONS

Lower extremity function, as measured by the SPPB, independently predicts hospitalization burden in outpatients with HFpEF. Additional studies are warranted to explore shared mechanisms and treatment implications of frailty in HFpEF.

Nutritional Risk by Mini Nutritional Assessment (MNA), but Not Anthropometric Measurements, Has a Good Discriminatory Power for Identifying Frailty in Elderly People: Data from Brazilian Secondary Care Clinic

OBJECTIVES

To investigate, in elderly individuals registered at a secondary outpatient clinic, the prevalence of frailty and pre-frailty and to identify the discriminatory power of anthropometric measurements and nutritional risk in identifying these conditions.

DESIGN

Cross-sectional study with data extracted from medical records.

SETTING AND PARTICIPANTS

Elderly patients (60+ years) from a geriatric outpatient clinic, located in the southeast area of São Paulo, Brazil.

MEASUREMENTS

Frailty was assessed using five criteria proposed by Fried et al (2001), with some modifications. Nutritional risk was identified using Mini Nutritional Assessment (MNA). Body weight and body height were measured and used to calculate the body mass index (BMI). The discriminatory power of these parameters for the identification of frailty was determined by Receiver Operating Characteristics (ROC) curves.

RESULTS

The final sample was composed of 254 patients, from which 31.1% were identified as frail and 53.5% as prefrail. The MNA indicated that 3.1% were malnourished and 35.4% were at risk of malnutrition. The BMI values 39.4% as overweight/obese and 19.9% as undernourished. As just the MNA revealed differences for frailty classification, only this parameter was investigated by ROC curve. The discriminatory power of the MNA for frailty presented a best cut-off point of ≤23.0 and the AUC was 0.812 (sensitivity=55.7; specificity=94.9), with a youden index of 0.5057 (95%CI= 0.3146-0.5946). MNA did not present sufficient discriminatory power to detect pre-frailty.

CONCLUSION

The MNA was capable of indicating frailty, but not pre-frailty in this sample. BMI did not display significant predictive power for frailty or pre-frailty.

Nutritional status and factors associated with non-institutionalized people over 75 years of age

OBJECTIVE

to determine the factors related to the risk of malnutrition in a non-institutionalized population over 75 years of age.

METHOD

a cross-sectional study was conducted using a questionnaire in a sample of 326 individuals over 75 years of age in Castellón (Spain), during 2015, and selected through intentional sampling.

RESULTS

Malnutrition prevalence was 2.8%. 26.9% of the individuals were at risk of malnutrition, whereas women presented a higher rate (31.5%). Women with a good overall health status showed a lower rate than men, 55% and 69%, respectively. Individuals that showed a lower risk of malnutrition are those with a positive perception than those who have a good overall health. Frail elderly people showed a higher risk of malnutrition (57.5%) compared to non-frail subjects (20.2%) p< 0.001.

CONCLUSION

Frail women, self-assessed health, overall health, and use of health care services (nursing consultation) were related to a higher risk of malnutrition.

From Hospital to Home to Participation: A Position Paper on Transition Planning Poststroke

Based on a review of the evidence, members of the American Congress of Rehabilitation Medicine Stroke Group's Movement Interventions Task Force offer these 5 recommendations to help improve transitions of care for patients and their caregivers: (1) improving communication processes; (2) using transition specialists; (3) implementing a patient-centered discharge checklist; (4) using standardized outcome measures; and (5) establishing partnerships with community wellness programs. Because of changes in health care policy, there are incentives to improve transitions during stroke rehabilitation. Although transition management programs often include multidisciplinary teams, medication management, caregiver education, and follow-up care management, there is a lack of a comprehensive and standardized approach to implement transition management protocols during poststroke rehabilitation. This article uses the Transitions of Care (TOC) model to conceptualize how to facilitate a comprehensive patient-centered hand off at discharge to maximize patient functioning and health. Specifically, this article reviews current guidelines and provides an evidence summary of several commonly cited approaches (Early Supported Discharge, planned predischarge home visits, discharge checklists) to manage TOC, followed by a description of documented barriers to effective transitions. Patient-centered and standardized transition management may improve community integration, activities of daily living performance, and quality of life for stroke survivors while also decreasing hospital readmission rates during the transition from hospital to home to community.

An Update on Protein, Leucine, Omega-3 Fatty Acids, and Vitamin D in the Prevention and Treatment of Sarcopenia and Functional Decline

Aging is associated with sarcopenia and functional decline, leading to frailty and disability. As a modifiable risk factor, nutrition may represent a target for preventing or postponing the onset of these geriatric conditions. Among nutrients, high-quality protein, leucine, vitamin D, and omega-3 polyunsaturated fatty acids (n-3 PUFA) are of particular interest for their demonstrated effects on skeletal muscle health. This narrative review aims to examine the recent observational and interventional evidence on the associations and the role of these nutrients in the muscle mass, strength, mobility, and physical function of free-living older adults, who are either healthy or at risk of frailty. Recent evidence supports a higher protein intake recommendation of 1.0⁻1.2 g/kg/day in healthy older adults; an evenly distributed mealtime protein intake or minimal protein per meal may be beneficial. In addition, vitamin D supplementation of 800⁻1000 IU, particularly when vitamin D status is low, and doses of ~3 g/day of n-3 PUFA may be favorable for physical function, muscle mass, and strength. Reviewed studies are highly heterogenous, yet the quantity, quality, and timing of intakes should be considered when designing intervention studies. Combined protein, leucine, vitamin D, and n-3 PUFA supplements may convey added benefits and may represent an intervention strategy in the prevention of sarcopenia and functional decline.

Home-Delivered Meals Postdischarge From Heart Failure Hospitalization

Background In patients with heart failure (HF), malnutrition and dietary sodium excess are common and may worsen outcomes. No prior studies have provided low-sodium, nutritionally complete meals following HF hospitalization. Methods and Results The GOURMET-HF study (Geriatric Out-of-Hospital Randomized Meal Trial in Heart Failure) randomized patients discharged from HF hospitalization to 4 weeks of home-delivered sodium-restricted Dietary Approaches to Stop Hypertension meals (DASH/SRD; 1500 mg sodium/d) versus usual care. The primary outcome was the between-group change in the Kansas City Cardiomyopathy Questionnaire summary score from discharge to 4 weeks postdischarge. Additional outcomes included changes in the Kansas City Cardiomyopathy Questionnaire clinical summary score and cardiac biomarkers. All patients were followed 12 weeks for death/all-cause readmission and potential diet-related adverse events (symptomatic hypotension, hyperkalemia, acute kidney injury). Sixty-six patients were randomized 1:1 at discharge to DASH/SRD versus usual care (age, 71±8 years; 30% female; ejection fraction, 39±18%). The Kansas City Cardiomyopathy Questionnaire summary score increased similarly between groups (DASH/SRD 46±23-59±20 versus usual care 43±19-53±24; P=0.38), but the Kansas City Cardiomyopathy Questionnaire clinical summary score increase tended to be greater in DASH/SRD participants (47±22-65±19 versus 45±20-55±26; P=0.053). Potentially diet-related adverse events were uncommon; 30-day HF readmissions (11% versus 27%; P=0.06) and days rehospitalized within that timeframe (17 versus 55; P=0.055) trended lower in DASH/SRD participants. Conclusions Home-delivered DASH/SRD after HF hospitalization appeared safe in selected patients and had directionally favorable effects on HF clinical status and 30-day readmissions. Larger studies are warranted to clarify the effects of postdischarge nutritional support in patients with HF. Clinical Trial Registration URL: https://www.clinicaltrials.gov .

Frailty and nutritional status in older people: the Mini Nutritional Assessment as a screening tool for the identification of frail subjects

INTRODUCTION

Frailty is a condition characterized by reduced resistance to low-level stress events, resulting from the progressive decline of multiple physiological systems observed with aging. Many factors can contribute to the pathogenesis of frailty, and nutritional status appears to play a key role. The objective of the study was to investigate the relationship between nutritional status, evaluated using Mini Nutritional Assessment (MNA), and frailty among older people.

PATIENTS AND METHODS

An observational study was carried out at the University Hospital "Tor Vergata" in Rome among patients aged 65 years or older, with or without hip fracture. The study sample included 62 patients hospitalized for a hip fracture and 50 outpatients without fracture. All subjects underwent blood sampling for laboratory assays and received a multidimensional geriatric evaluation comprising Activity of Daily Living (ADL), Instrumental Activity of Daily Living (IADL), Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS), and MNA. Comorbidity was assessed using the Cumulative Illness Rating Scale for Geriatrics (CIRS-G). Muscle strength was measured by handgrip dynamometry, and frailty score was calculated using the Survey of Health, Ageing and Retirement in Europe-Frailty Index (SHARE-FI).

RESULTS

Approximately 38% of the study population was frail, with the prevalence of frailty being greater among hospitalized older patients. Among frail subjects, 65% were at risk of malnutrition (RMN) and 10% were malnourished. The prevalence and RMN progressively diminished in the pre-frail group and not frail group. Nutritional status was closely associated with the degree of frailty, and in a logistic regression, MNA was the best variable predicting both pre-frailty and frailty.

DISCUSSION AND CONCLUSION

Malnutrition contributes to the development of frailty. MNA can generate vital information to help identify a substantial part of both frail and pre-frail patients at low cost and care.

What do we know about frailty in the acute care setting? A scoping review

Background

The ability of acute care providers to cope with the influx of frail older patients is increasingly stressed, and changes need to be made to improve care provided to older adults. Our purpose was to conduct a scoping review to map and synthesize the literature addressing frailty in the acute care setting in order to understand how to tackle this challenge. We also aimed to highlight the current gaps in frailty research.

Methods

This scoping review included original research articles with acutely-ill Emergency Medical Services (EMS) or hospitalized older patients who were identified as frail by the authors. We searched Medline, CINAHL, Embase, PsycINFO, Eric, and Cochrane from January 2000 to September 2015.

Results

Our database search initially resulted in 8658 articles and 617 were eligible. In 67% of the articles the authors identified their participants as frail but did not report on how they measured frailty. Among the 204 articles that did measure frailty, the most common disciplines were geriatrics (14%), emergency department (14%), and general medicine (11%). In total, 89 measures were used. This included 13 established tools, used in 51% of the articles, and 35 non-frailty tools, used in 24% of the articles. The most commonly used tools were the Clinical Frailty Scale, the Frailty Index, and the Frailty Phenotype (12% each). Most often (44%) researchers used frailty tools to predict adverse health outcomes. In 74% of the cases frailty predicted the outcome examined, typically mortality and length of stay.

Conclusions

Most studies (83%) were conducted in non-geriatric disciplines and two thirds of the articles identified participants as frail without measuring frailty. There was great variability in tools used and more recently published studies were more likely to use established frailty tools. Overall, frailty appears to be a good predictor of adverse health outcomes. For frailty to be implemented in clinical practice frailty tools should help formulate the care plan and improve shared decision making. How this will happen has yet to be determined.

The Prevalence of Frailty and its Associated Factors in Japanese Hemodialysis Patients

The population undergoing dialysis is aging worldwide, particularly in Japan. The clinical condition of frailty is the most problematic expression in the elderly population. Potential pathophysiological factors of frailty present in patients with CKD and are accentuated in patients with ESRD. The aim of this study was to identify the prevalence and predictors of frailty in Japanese HD patients. This study was a multicenter, cross-sectional and observational investigation conducted at 6 institutions. To evaluate frailty, the modified Fried’s frailty phenotype adjusted for Japanese as the self-reported questionnaire was used. Of the 542 patients visiting each institution, 388 were enrolled in this study. In total, 26.0% of participants were categorized as not-frailty, 52.6% as pre-frailty and 21.4% as frailty. The prevalence of frailty increased steadily with age and was more prevalent in females than in males and the subjects with frailty received polypharmacy. A multivariate logistic regression analysis revealed that the factors independently associated with frailty were the following: female gender (odds ratio [OR] = 3.661, 95% confidence interval [CI] 1.398-9.588), age (OR = 1.065, 95% CI 1.014-1.119), age ≥ 75 years old (OR = 4.892, 95% CI 1.715-13.955), body mass index (BMI) < 18.5 (OR = 0.110, 95% CI 0.0293-0.416), number of medications being taken (OR = 1.351, 95% CI 1.163-1.570), diabetes mellitus (DM) (OR = 2.765, 95% CI 1.081-7.071) and MNA-SF ≤ 11 (OR = 7.405, 95% CI 2.732-20.072). Frailty was associated with the accumulation of risk factors. The prevalence of frailty in Japanese patients with HD was relatively lower than that previously reported in Western developed countries; however, it was extremely high compared to the general population regardless of age. Our findings suggest that frailty might be associated with an increase in the prevalence of adverse health outcomes in patients with HD.

Nutritional Status and Frailty in Community-Dwelling Older Korean Adults: The Korean Frailty and Aging Cohort Study

OBJECTIVES

To examine the association between nutritional status and frailty in older adults.

DESIGN

Cross-sectional study.

SETTING

Community-dwelling older adults were recruited from 10 study sites in South Korea.

PARTICIPANTS

1473 volunteers aged 70-84 years without severe cognitive impairment and who participated in the Korean Frailty and Aging Cohort Study (KFACS) conducted in 2016.

MEASUREMENTS

Nutritional status was measured using the Mini Nutritional Assessment Short Form (MNA-SF). Frailty was assessed with the Fried's frailty index. The relationship between nutritional status and frailty was examined using the multinomial regression analysis, adjusting for covariates.

RESULTS

Of the respondents 14.3% had poor nutrition (0.8% with malnutrition, 13.5% at risk of malnutrition). There were 10.7% who were frail, with 48.5% being prefrail, and 40.8% robust. Poor nutrition was related to a significantly increased risk of being prefrail (odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.09-2.32) and frail (OR: 3.30, 95% CI: 1.96-5.54).

CONCLUSION

Poor nutritional status is strongly associated with frailty in older adults. More research to understand the interdependency between nutritional status and frailty may lead to better management of the two geriatric conditions.

The association between nutritional status and frailty characteristics among geriatric outpatients

BACKGROUND

Frailty is a common clinical syndrome in older adults and is associated with an increased risk of poor health outcomes, e.g. falls, disability, hospitalization, and mortality. Nutritional status might be an important factor contributing to frailty. This study aims to describe the association between nutritional status and characteristics of frailty in patients attending a geriatric outpatient clinic.

METHODS

Clinical data was collected of 475 patients who visited the geriatric outpatient department of a Dutch hospital between 2005 and 2010. Frailty was determined by: incontinence, Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), mobility, Geriatric Depression Scale (GDS) and Mini Mental State Exam (MMSE). Nutritional status was represented by the Mini Nutritional Assessment (MNA) and plasma concentrations of several micronutrients, whereby MNA< 17 indicated malnutrition and MNA 17-23.5 indicated risk of malnutrition. 'More frail' patients (≥3 frailty characteristics) were compared to 'less frail' patients (<3 frailty characteristics) with logistic regression analyses, adjusted for age, sex and other important covariates.

RESULTS

Of 404 patients with complete data, mean age (SD) was 80 (7) years and 34% was male. Prevalence of 'more frail' patients was 47%. Prevalence of malnutrition and risk of malnutrition was 16% and 56% respectively. Malnutrition and risk of malnutrition were both independently related to being 'more frail', with ORs (95% CI) of 8.1 [3.5-18.8] and 3.1 [1.7-5.5] respectively. This association was driven by functional decline (ADL, IADL and mobility) and depression (GDS), but not by cognitive impairment (MMSE). None of the micronutrient plasma concentrations were related to frailty.

CONCLUSION

In geriatric outpatients, malnutrition is independently related to having ≥3 frailty characteristics. Assessing nutritional status could prove usefulness in early clinical detection and prevention of frailty.

Effects of a Home-Based and Volunteer-Administered Physical Training, Nutritional, and Social Support Program on Malnutrition and Frailty in Older Persons: A Randomized Controlled Trial

OBJECTIVES

The aim of this study was to examine the effects of a home-based and volunteer-administered physical training and nutritional intervention program compared with social support intervention on nutritional and frailty status in prefrail and frail community-dwelling older persons.

DESIGN

This was a randomized controlled trial in which community-dwelling persons (mean age = 83 years) were recruited and randomly assigned to the physical training and nutritional intervention group (PTN, n = 39) and the social support group (SoSu, n = 41). The study was conducted by trained lay nonprofessionals.

SETTING

The community-dwelling older persons in both groups were visited twice a week by trained nonprofessional volunteers (buddies) in Vienna, Austria.

PARTICIPANTS

Eighty prefrail and frail adults aged 65 years or older.

INTERVENTION

In the PTN group, both the buddies and older persons performed 6 strength exercises within a circuit training session and discussed nutrition-related aspects. The active control group (SoSu) had the opportunity to perform cognitive training in addition to the social contact.

MEASUREMENTS

Outcome measures as nutritional (Mini Nutritional Assessment long form [MNA-LF]) and frailty status (Frailty Instrument for Primary Care of the Survey of Health, Ageing and Retirement in Europe [SHARE-FI]) were obtained at baseline and after 12 weeks.

RESULTS

Significant improvements in the MNA-LF score (1.54 points, 95% confidence interval [CI] 0.51-2.56; P = .004) and the SHARE-FI score (-0.71 discrete factor score values, 95% CI -1.07, -0.35; P < .001) were observed in the PTN group after 12 weeks. In both groups, the prevalence of impaired nutritional status and frailty decreased significantly over time. The prevalence of impaired nutritional status decreased by 25% in the PTN group and by 23% in the SoSu group. Moreover, the prevalence of frailty decreased by 17% in the PTN group and by 16% in the SoSu group. The presence of impaired nutritional status at baseline was independently associated with greater changes in the nutritional (adjusted odds ratio [OR] 3.18, 95% CI 1.26-7.98; P = .014) and frailty status (adjusted OR 3.16, 95% CI 1.01-9.93; P = .049) after 12 weeks.

CONCLUSION

The results indicate that a home-based physical training, nutritional, and social support intervention conducted by nonprofessionals is feasible and can help to tackle malnutrition and frailty in older persons living at home. Furthermore, social support alone also can result in improvement. In particular, older adults with impaired nutritional status at baseline can benefit more from the intervention. Such a home visit program might also have the potential to prevent future health risks and could allay isolation and loneliness.

Quantitative assessment of locomotive syndrome by the loco-check questionnaire in older Japanese females

[Purpose] Locomotive syndrome (LS) is a condition by which older people may require care service because of problems with locomotive organs. This study examined whether the loco-check, a 7-item questionnaire, is useful for quantitatively assessing the severity of LS. [Subjects and Methods] Seventy-one community dwelling Japanese females aged 64–96 years (81.7 ± 8.0 years) participated in this study. The associations of the loco-check with thigh muscle mass measured by X-ray CT, physical performance, nutritional status, and quality of life (QOL) were investigated. [Results] The results showed that the number of times that “yes” was selected in the loco-check was significantly correlated with thigh muscle mass, major measures of physical performance, nutritional status, and QOL. This number was also significantly larger in the participants experiencing falling, fracture, and lumbar pain than in those without these episodes. [Conclusion] These results suggest that the loco-check might be useful for quantitatively evaluating LS.

Frailty Status in Older Adults Is Related to Alterations in Indoleamine 2,3-Dioxygenase 1 and Guanosine Triphosphate Cyclohydrolase I Enzymatic Pathways

BACKGROUND

Frailty is a multidimensional syndrome correlated to the loss of homeostasis and increased vulnerability to stressors, which is associated with increase in the risk of disability, comorbidity, hospitalization, and death in the elderly. It is based on the interplay of physiological, psychological, social, and environmental factors.

OBJECTIVES

Because aging involves a detrimental immune response, this work aimed to assess the possible role of chronic low-grade immune stimulation on frailty status in the elderly.

METHODS

Biomarkers involved in indoleamine 2,3-dioxygenase 1 and guanosine triphosphate cyclohydrolase I enzymatic pathways (namely neopterin, tryptophan, kynurenine, phenylalanine, tyrosine, and nitrite) were analyzed in a population of Spanish older adults aged 65 years and above, and their relationships with frailty status were evaluated.

RESULTS

Significant increases in neopterin levels, kynurenine/tryptophan ratio, and phenylalanine/tyrosine ratio, and significant decreases in tryptophan, nitrite and tyrosine concentrations in frail individuals compared with nonfrail persons were obtained. Significant correlations were also observed between immune biomarkers, indicating they change in parallel, thus, pointing to interrelated causes. Besides, reference ranges for a number of immune biomarkers in the population of robust older adults were established for the first time.

CONCLUSIONS

Results obtained in the present study are consistent with the idea that frailty status in the elderly is associated with an additional degree of immune stimulation, manifested in a more intense disturbance of indoleamine 2,3-dioxygenase 1 and guanosine triphosphate cyclohydrolase I pathways than in nonfrail or prefrail older adults.

Impact of a lay-led home-based intervention programme on quality of life in community-dwelling pre-frail and frail older adults: a randomized controlled trial

BACKGROUND

Due to the demographic ageing process and the increasing number of pre-frail and frail individuals, new lifestyle interventions to enhance the quality of life (QoL) in community-dwelling older adults are necessary. Therefore, we performed a randomised controlled trial (RCT) to compare effects of a lay-led home-based physical and nutritional intervention programme with social support alone on different QoL domains in community-dwelling pre-frail and frail older adults.

METHODS

In this analysis within a RCT (12 weeks), lay volunteers visited one-on-one pre-frail or frail older adults at home twice a week. Participants in the physical training and nutritional intervention (PTN) group performed six strength exercises and discussed main nutritional issues during each visit. The social support (SOSU) group received home visits twice a week for social exchanges. The QoL was assessed with the WHOQOL-BREF and the WHOQOL-OLD instruments. Analyses of covariance (ANCOVA) were used to examine differences between groups with baseline values as the covariate. Changes within groups were assessed with paired t-tests.

RESULTS

Eighty participants (n = 39 in the PTN group and n = 41 in the SOSU group) were included. No significant differences were found between the two groups except in past, present and future activities domain [β = 3.66 (95% confidence interval 0.13 to 7.18)] in favour of the PTN group. However, there was some evidence of greater within group improvements in the PTN group particularly in overall QoL, social relations and social participation. In the SOSU group, no significant effect was observed in any QoL domain.

CONCLUSION

A combination of a home-based physical and nutritional intervention was not more effective compared to social support alone, on QoL in community-dwelling pre-frail and frail older adults. However, the small but significant improvement within the PTN group suggests that a home-based physical and nutritional intervention delivered by volunteers may influence the QoL in a positive way.

TRIAL REGISTRATION

The study protocol was registered on 6 November 2013 at ClinicalTrials.gov (identifier: NCT01991639 ).

Frailty, Aging, and Cardiovascular Surgery

Older adults make up an ever-increasing number of patients presenting for surgery, and a significant percentage of these patients will be frail. Frailty is a geriatric syndrome that has been conceptualized as decreased reserve when confronted with stressors, although the precise definition of frailty has not been easy to standardize. The 2 most popular approaches to define frailty are the phenotypic approach and the deficit accumulation approach, although at least 20 tools have been developed, which has made comparison across studies difficult. In epidemiologic studies, baseline frailty has been associated with poor outcomes in both community cohorts and hospitalized patients. Specifically in cardiac surgery (including transcatheter aortic valve implantation procedures), frailty has been strongly associated with postoperative mortality and morbidity, and thus frailty likely improves the identification of high-risk patients beyond known risk scores. For perioperative physicians then, the question arises of how to incorporate this information into perioperative care. To date, 2 thrusts of research and clinical practice have emerged: (1) preoperative identification of high-risk patients to guide both patient expectations and surgical decision-making; and (2) perioperative optimization strategies for frail patients. However, despite the strong association of frailty and poor outcomes, there is a lack of well-designed trials that have examined perioperative interventions with a specific focus on frail patients undergoing cardiac surgery. Thus, in many cases, principles of geriatric care may need to be applied. Further research is needed to standardize and implement the feasible definitions of frailty and examine perioperative interventions for frail patients undergoing cardiac surgery.

Low FT3: a possible marker of frailty in the elderly

Introduction

Frailty is associated with a functional decline of multiple physiological systems, of which they may be a cause or consequence. The objective of the study was to evaluate the prevalence of thyroid hormone modifications in elderly frail subjects and its relationship with frailty.

Study population and methods

An observational study was carried out at the University Hospital “Tor Vergata” in Rome among ambulatory and hospitalized patients. The study population consisted of 112 elderly subjects: 62 were hospitalized following hip fracture and 50 control subjects were outpatients. Participating patients received a multidimensional geriatric evaluation. The Survey of Health, Ageing and Retirement in Europe Frailty Instrument (SHARE-FI) was used to assess the degree of frailty. Thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) were measured to evaluate thyroid status.

Results

FT3, but not FT4, was significantly correlated with Frailty score, both in patients with hip fracture and in patients from the control group. In the entire study population, FT3 under normal limits is effective in discriminating frail/prefrail subjects from nonfrail subjects.

Discussion

The reduction in serum concentrations of FT3 is a clear manifestation of stress associated with fractures. Numerous preexisting factors, such as the fracture patients’ nutritional status, sarcopenia, disability and comorbidities, which characterize the condition of frailty and influence its pathogenesis, are strongly correlated with FT3 values, suggesting the existence of latent nonthyroidal illness syndrome (NTIS).

Conclusion

We conclude that measuring FT3 can be a useful laboratory parameter in clinical assessment, which can play an important role in identifying vulnerable elderly subjects and in quantifying the condition of frailty.

Impact of a Home-Based Physical and Nutritional Intervention Program Conducted by Lay-Volunteers on Handgrip Strength in Prefrail and Frail Older Adults: A Randomized Control Trial

A randomized controlled trial was performed to compare the effects of a home-based physical and nutritional intervention program carried out by lay-volunteers to home visits with social support alone. Buddies visited 80 prefrail or frail older persons at home twice a week for 12 weeks. The physical training and nutrition group (PTN, n = 39) performed two sets of six strength exercises, discussed nutritional topics and received social support. The social support group (SoSu, n = 41) received home visits with social support only. In the PTN group, handgrip strength increased significantly by 2.4 kg (95% CI: 1.0–3.8). In the SoSu group we did not see a significant improvement. However, no significant between-group difference was found. Physical performance increased in both groups, although with a higher increase of 1.0 point (95% CI: 0.1–2.0) in the PTN group. In none of the groups muscle mass changed. Further results showed that frail individuals benefit more from the intervention than prefrail individuals (OR: 2.78; 95% CI: 1.01–7.66). Handgrip strength in the intervention group increased by a clinically relevant value and this effect is comparable to that obtained by health-care professionals. Therefore, home visits with a physical training and nutritional program could offer a new perspective in the care of community-dwelling prefrail and frail older persons.
