Abstract
BACKGROUND Nutrition and exercise are important interventions for sarcopenia. There were few studies on oral oligopeptide nutrition preparations combined with exercise to intervene in the older people with sarcopenia. The aim of this study was to verify the effectiveness of oligopeptide nutrition preparation combined with exercise intervention on the older people with sarcopenia in community. METHODS A total of 219 subjects aged 65 years or older with sarcopenia were randomly divided into 4 groups. The nutrition group (n = 58) was given individualized nutrition education and oral oligopeptide nutrition preparation. The exercise group (n = 50) received exercise intervention. The combined group (n = 52) received both oral nutrition preparation and exercise interventions. The control group (n = 59) only received individualized nutrition education. The nutrition preparation can provide energy 185kcal and protein 24.2g per day. The exercise intervention including warm-up exercise, resistance exercise and aerobic exercise, the training time was 60min for 5 times every week. The intervention lasted for 16 weeks. Hand grip strength, gait speed, body composition and hematology parameters were measured before and after intervention. RESULTS A total of 159 subjects completed the study. Compared with baseline, the left grip strength and 6-m walking speed of the subjects in nutrition group increased significantly after the intervention, and the grip strength of both hands in exercise group and combined group increased significantly. The body weight of the subjects in nutrition group, exercise group and combined group increased significantly after intervention, but no increase in soft lean mass (SLM) and skeletal muscle mass (SMM) was observed in any of the four groups. The fat-free mass (FFM) of the legs of the control group, exercise group and nutrition group decreased after intervention, and only the FFM of the legs of the combined group maintained the level before the intervention. CONCLUSION Both oral peptide nutrition and exercise interventions can improve the muscle strength or function of the older people with sarcopenia. However, there were no increases in muscle mass observed. TRIAL REGISTRATION ChiCTR, ChiCTR2100052135. Registered 20 October 2021, https://www.chictr.org.cn/showproj.html?proj=135743.

Abstract
The Tilburg Frailty Indicator (TFI) is a validated tool for determining frailty in older adults. This study examined the validity and accuracy of the TFI Part B (TFI-B) in a North American context. Seventy-two individuals ≥ 65 years of age recruited from a rural geriatric medicine clinic completed a set of self-reported and performance-based measures, including TFI-B. Frailty level was determined using modified Fried's Frailty Phenotype (FFP). Pearson correlation coefficients (r) assessed the concurrent relationships between the TFI-B and other measures. Accuracy of the TFI-B in classifying frailty level was assessed using assessing area under the curve (AUC). The TFI-B scores showed low correlations (r < 0.4) with gait speed and grip, suggesting that the TFI-B did not consider frailty as merely a physical problem. The AUC of 0.82 indicated that the TFI-B scores accurately classified frail versus non-frail individuals. The score of ≥ 5 on the TFI-B scores showed satisfactory sensitivity/specificity (73%/77%) and excellent negative predictive value (91.95%). This indicates that a TFI-B score of < 5 can be used to rule out frailty.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph192316260. [PMID: 36498332 PMCID: PMC9738370 DOI: 10.3390/ijerph192316260] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/02/2022] [Accepted: 12/03/2022] [Indexed: 06/01/2023]
Abstract
This study aimed to investigate the association between dietary problems and frailty according to tooth loss in older Japanese people. This cross-sectional study included 160 older people (mean age 82.6 years) from Japan. Frailty status was assessed using the Study of Osteoporotic Fractures (SOF) criteria, which consists of (i) weight loss > 5% in the past year, (ii) inability to perform five chair stands, and (iii) self-perceived reduced energy level. Frailty was defined as the presence of ≥2 items of SOF criteria. Multivariate logistic regression analyses were performed with frailty as the dependent variable and dietary problems as the independent variable, stratified according to having <20 teeth. Low appetite and no enjoyment of eating were associated with frailty after adjusting for covariates in participants with <20 teeth. Dietary problems, including low appetite, eating alone, and negative attitudes toward enjoyment of eating were associated with a self-perceived reduced energy level in participants with <20 teeth. However, this association was not observed in participants with ≥20 teeth. In older people with fewer teeth, dietary problems have been suggested to be associated with frailty. Therefore, it may be necessary to pay attention to dietary problems, especially in older people with tooth loss.

Abstract
The impact of social participation (SP) on the health of the elderly has been widely recognized, and urban-rural differences in social participation have attracted attention. However, few studies discussed the impact of social participation on specific health indicators and the further subdivision of urban-rural differences. This research aims to use the dimensions of interpersonal behaviors and population density rather than simple urban-rural distinctions to justify community differences and compare these differences' direct and indirect effects on grip strength. This study used 15,871 respondents aged over 50 years from the China Health and Retirement Longitudinal Study (CHARLS). An SEM (Structural Equation Modeling) analysis was used to explore the joint effect of interpersonal behavior and population density on social participation and the consequent impact on changes in grip strength and compare the differences among different genders, ages, wealth levels, and family relationships. The results indicated that community differences characterized by interpersonal behavior and population density have direct effects on grip strength and indirect effects on it through social participation. The conclusion is that the frequency of social activities, such as mah-jong and dancing in the Metropolitan Fringe and county-level cities is higher than that in Metropolitan centers. The high frequency of these activities has a positive and indirect impact on grip strength, and community differences have a more significant impact on women's social participation than men. However, the direct effect of community differences as defined by interpersonal communication and population density on grip strength is greater than the indirect effect of other factors through social participation.

Effects of Exergames and Protein Supplementation on Body Composition and Musculoskeletal Function of Prefrail Community-Dwelling Older Women: A Randomized, Controlled Clinical Trial. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18179324. [PMID: 34501915 PMCID: PMC8430494 DOI: 10.3390/ijerph18179324] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 07/29/2021] [Accepted: 08/13/2021] [Indexed: 12/20/2022]
Abstract
This study aimed to investigate the effects of exergames and protein supplementation on the body composition and musculoskeletal function of pre-frail older women. Methods: A randomized controlled clinical trial was conducted with 90 pre-frail older women (71.2 ± 4.5 years old) divided into five groups: control (CG); exergames training (ETG); protein supplementation (PSG); exergames combined with protein supplementation (ETPSG); exergames combined with isoenergetic supplementation (ETISG). The primary outcomes were pre-frailty status, body composition (appendicular muscle mass (ASM); appendicular muscle mass index (ASMI)) assessed by dual energy X-ray absorptiometry and gastrocnemius muscle architecture via ultrasound. Secondary outcomes were protein intake, plasma levels of interleukin (IL)-6, plantar and dorsiflexion isokinetic peak torque, and handgrip strength (HS). Data were analyzed using an ANOVA mixed model test and Bonferroni post hoc test (p < 0.05). The ETG showed a reduction of ASM (16.7 ± 3.4 vs. 16.1 ± 3.3 kg; Δ = −0.5; p = 0.02; d = 0.26) and ASMI (6.8 ± 0.9 vs. 6.5 ± 0.9 kg; Δ = −0.2; p = 0.03; d = 0.35), without changing ASM in other groups. The average protein intake in the supplemented groups (PSG and ETPSG) was 1.1 ± 0.2 g/kg/day. The dorsiflexion peak torque increased 11.4% in ETPSG (16.3 ± 2.5 vs. 18.4 ± 4.2 Nm; p = 0.021; d = −0.58). The HS increased by 13.7% in ETG (20.1 ± 7.2 vs. 23.3 ± 6.2 kg, Δ = 3.2 ± 4.9, p = 0.004, d = −0.48). The fatigue/exhaustion reduced by 100% in ETG, 75% in PSG, and 100% in ETPSG. Physical training with exergames associated with protein supplementation reversed pre-frailty status, improved the ankle dorsiflexors torque, and ameliorated fatigue/exhaustion in pre-frail older women.

Abstract
BACKGROUND & AIMS The use of handgrip strength (HGS) as a proxy of nutritional status in sick children has not been studied. This study created HGS centile charts in healthy children and explored the utility of HGS z-scores as markers of body composition and screening of malnutrition risk in sick children. METHODS Data from 535 healthy children aged 5-16 years were used for the development of HGS centiles adjusted either for age or height. In 595 sick children, relationships between HGS z-scores with body composition, malnutrition risk (Paediatric Yorkhill Malnutrition Score-PYMS), length of hospital stay (LOS) and biomarkers of disease severity were explored. The use of HGS z-score to identify sick children in need of further dietetic assessment was investigated. RESULTS Children scoring at high malnutrition risk with PYMS had lower HGS z-scores for age (by 0.51 SD, p < 0.001) and height (by 0.46 SD, p = 0.001) than those who scored low. A HGS z-score at cut-offs of -0.81 SD and -1.2 SD for age and height, respectively, was predictive of need for dietetic intervention in sick children with sensitivity of 79% and 70% and specificity of 56% and 69%, respectively. HGS z-scores were predictive of fat free mass (FFM) in sick and healthy (all p < 0.001) children, while fat mass was not. HGS z-scores were inversely related with plasma CRP (rho, age: -0.21; height: -0.23, both p = 0.001). HGS was not predictive of LOS. CONCLUSION HGS is predictive of FFM, could compliment assessment of malnutrition risk, and may help identify children for further dietetic intervention on admission to hospital.

Abstract
PURPOSE This study aims to examine the frailty transition patterns of older adults recruited from both community and residential care settings within a 5-year period, and to identify the physical and psychosocial factors associated with the transitions. DESIGN This study is a secondary data analysis of a longitudinal study for tracking the change of health status of older adults 60 years of age or older. Participants who had undergone at least two assessments during 2013-2017 were selected for analysis. Guided by the Gobben's Frailty Model, biopsychosocial predictors were comprehensively identified from the literature, and their relationship to frailty state transition was explored. METHODS We compared the baseline characteristics of participants at the frail, pre-frail, and robust states (categorized using the Fried Frailty Index). A generalized estimating equation was used to identify factors associated with an improvement or a deterioration in frailty. The probability of transitions between frailty states was calculated. FINDINGS Among the 306 participants, 19% (n = 59) improved and 30% (n = 92) declined in frailty within the project period. Sleep difficulties (odds ratio [OR] = 1.76; 95% confidence interval [CI]: 1.07-2.90; p = .027), better cognitive status (OR = 0.80-0.84; 95% CI: 0.66-0.98 and 0.73-2.73; p = .031 and .018), good nutritional status (OR = 0.74; 95% CI: 0.59-0.91; p = .005), slow mobility (OR = 1.03-1.13; 95% CI: 1.00-1.05 and 1.03-1.25; p = .047 and .014), hearing impairment (OR = 2.83; 95% CI: 1.00-8.01; p = .05), better quality of health-physical domain (OR = 0.95; 95% CI: 0.92-0.99; p = .006), and better functional ability (OR = 0.85-0.97; 95% CI: 0.79-0.92 and 0.96-0.99; p < .001 and p = .003) were significant associated factors in the worsening group. More physical activity (OR = 1.01; 95% CI: 1.00-1.01 and 1.01-1.02; p = .026 and p < .001), hearing impairment (OR = 0.26; 95% CI: 0.08-0.86; p = .028), and slow mobility (OR = 0.93; 95% CI: 0.87-1.00; p = .037) were significant associated factors in the improvement group. CONCLUSIONS Frailty is a crucial global public health issue. This study provides evidence for nurses to holistically consider the associated factors and to design effective interventions to combat frailty in our ageing society. CLINICAL RELEVANCE Frailty is a transient state that can be reversed. Professional nurses working in both community and residential care settings should be able to identify older adults at risk and improve their health conditions appropriately.

Abstract
BACKGROUND Malignancies are the leading cause of disease burden in Australia, comprising 19% of total diseases. Approximately 1 in 4 men and 1 in 6 women die from malignancies by 85 years of age, with patients aged 65 years and older contributing to 58% of diagnoses and 76% of cancer mortality. In the context of malignancy-related disease and age-related degeneration, there is a need for comprehensive assessment of older patients to plan for appropriate management and predict prognosis. The utility of available comprehensive geriatric assessment tools has been limited in routine practice because of their time-consuming nature, despite their informing clearer understanding of patients' functional status, better clinical decision making, prevention of unpredictable admissions and emergency department overload, and support services planning. Though there are several promising tools available, there is a lack of literature on tools that can comprehensively assess functional status in an expedited fashion. OBJECTIVE This study aimed to document functional status and comorbidities among a geriatric oncology patient cohort attending a regionally located, dedicated cancer care facility, using the completed Adelaide tool assessments. This study documents cohort characteristics, including sociodemographics, malignancy type, and comorbidities. Secondarily, we observed the utility of an abridged functional assessment in the multidisciplinary team (MDT) management of older cancer patients. METHODS The study comprised a facility-based cross-sectional audit of results obtained from a screening tool administered to patients aged 65 years and older and attending an outpatient medical oncology clinic for management of cancer from late 2015 to 2017. Data relating to five domains were collected, including instrumental activities of daily living, activities of daily living, performance status, unintended weight loss, and exhaustion. Sociodemographic and disease-related factors were summarized as frequencies with percentages or mean with SD. Distribution of functional status based on sociodemographic characteristics, living status, disease-related factors, and comorbidities was analyzed using a chi-square test. Cumulative dependencies in the five domains were identified, and patients were classified as fit, vulnerable, or frail. Supplementary review of presentation notes for cases discussed at MDT meetings was undertaken to identify discrepancies. RESULTS A majority of the study population showed poor functional status, with 88.7% (243/274) categorized as vulnerable and 8.4% (23/274) as frail. Exhaustion and unintended weight loss were identified as the most common contributors to dependency. Polypharmacy was strongly associated with decreased functional status. CONCLUSIONS The outcomes of this study are congruent with the existence of dependency in various domains, and with similar research in geriatric oncology. The Adelaide tool provided a useful basis for MDT discussion and management, where cases were referred to the MDT. We recommend further examination of the tool's utility and impact in clinical decision making, and the distribution of dependencies in a rural cohort compared with metropolitan patients.

Abstract
Background: Sleep health-related issues, such as poor subjective sleep quality during the night and nocturnal wakefulness, have been a focus of recent research on frailty. However, current trends regarding the chronotypes of older individuals with frailty have not been well documented, and information on the impact of frailty on circadian rest-activity patterns is limited. The aim of this research was to clarify the relationship among frailty, nonparametric rest-activity patterns, and chronotype in older community-dwelling subjects. Method: A survey was conducted between June and December 2018, and the participants of this study were recruited from among community-dwellers aged 60 years or older living in Akita prefecture, Japan. The frailty phenotype defined by the National Center for Geriatrics and Gerontology Study of Geriatric Syndromes (NCGG-SGS) was used to evaluate the frailty status of each participant. To evaluate nonparametric rest-activity rhythm (RAR) parameters (e.g., interdaily stability [IS], intradaily variability [IV], and relative amplitude [RA]), each participant wore an Actiwatch Spectrum Plus device on his or her non-dominant wrist for seven continuous days without removal. The Munich chronotype questionnaire-Japanese version (MCTQ-J) was also used to measure the midpoint of sleep in free days (MSF). Results: The final study cohort was composed of 105 participants (85.7% women) and was divided into 58 non-frail subjects, 45 pre-frail subjects, and 2 frail subjects. According to a binomial logistic regression analysis, the pre-frail individuals had a weaker grip strength (coefficient [beta], -0.18; odds ratio, 0.84; 95% confidence interval [CI], 0.76-0.93; p = .001) and a lower RA (beta, -8.78; odds ratio, 0.0002; 95% CI, 0.00-0.15; p = .01). In addition, correlation analyses also showed that the MSF was negatively associated with the RA in the pre-frail group (r = -0.30, p < .05) and positively correlated with the RA in the non-frail group (r = 0.26, p < .05); furthermore, the MSF of the pre-frail group occurred at a later time than that of the non-frail one (p = .03). Conclusion: The present study provides grounds for our proposal that pre-frailty is significantly associated with a low grip power and relative imbalance between rest and active statuses as indexed using nonparametric RAR parameters. Furthermore, elderly individuals with pre-frailty or frailty may have a later MSF time. However, these potential findings need to be validated in future research.
