Comparative Efficacy of Different Protein Supplements on Muscle Mass, Strength, and Physical Indices of Sarcopenia among Community-Dwelling, Hospitalized or Institutionalized Older Adults Undergoing Resistance Training: A Network Meta-Analysis of Randomized Controlled Trials.

Aging-related sarcopenia exerts harmful impacts on muscle mass, strength, and physical mobility. Protein supplementation has been demonstrated to augment efficacy of resistance training (RT) in elderly. This study compared the relative effects of different protein supplements on muscle mass, strength, and mobility outcomes in middle-aged and older individuals undergoing RT. A comprehensive search of online databases was performed to identify randomized controlled trials (RCTs) examining the efficacy of protein supplement plus RT in untrained community-dwelling adults, hospitalized, or institutionalized residents who suffered acute or chronic health conditions. Network meta-analysis (NMA) was performed using a frequentist method for all analyses. Treatment effects for main outcomes were expressed as standard mean difference (SMD) with 95% confidence interval (CI). We used the surface-under-the cumulative-ranking (SUCRA) scores to rank probabilities of effect estimation among all identified treatments. Meta-regression analyses were performed to identify any relevant moderator of the treatment efficacy and results were expressed as ß with 95% credible interval (CrI). We finally included 78 RCTs (5272 participants) for analyses. Among the six protein sources identified in this NMA, namely whey, milk, casein, meat, soy, and peanut, whey supplement yielded the most effective treatments augmenting efficacy of RT on muscle mass (SMD = 1.29, 95% CI: 0.96, 1.62; SUCRA = 0.86), handgrip strength (SMD = 1.46, 95% CI: 0.92, 2.00; SUCRA = 0.85), and walking speed (SMD = 0.73, 95% CI: 0.39, 1.07; SUCRA = 0.84). Participant's health condition, sex, and supplementation dose were significant factors moderating the treatment efficacy on muscle mass (ß = 0.74; 95% CrI: 0.22, 1.25), handgrip strength (ß = -1.72; 95% CrI: -2.68, -0.77), and leg strength (ß = 0.76; 95% CrI: 0.06, 1.47), respectively. Our findings suggest whey protein yields the optimal supplements to counter sarcopenia in older individuals undergoing RT.

A protocol for stakeholder engagement in deliver-EE: A pragmatic randomized comparative effectiveness trial evaluating effects of meal delivery on the ability of homebound older adults to remain in the community.

BACKGROUND: Few clinical trials include a detailed protocol for stakeholder engagement in the design and execution of the clinical trial. Deliver-EE is a pragmatic clinical trial to assess how different types of home-delivered meals can affect older adults' health and well-being. We present the protocol for stakeholder engagement in this national, multi-site trial and initial findings from our efforts. METHODS: Twenty-nine participants were recruited to two stakeholder advisory panels. The "Lived Experience Perspectives" panel is defined as the clients, caregivers, and meal delivery drivers with first-hand knowledge and lived experiences with meal delivery. The "System Perspectives" panel is defined as representatives from the larger financial, clinical, regulatory, and operational environments in which meal delivery to homebound older adults operate. Together, these two groups holistically represent interested parties that coordinate the interdependent elements of meal delivery to homebound older adults in order to: 1) inform our understanding of what matters most to older adults, their families, and the larger health and social care systems; 2) provide strategies to overcome challenges conducting the study; 3) enhance dissemination and uptake of study findings; and 4) identify opportunities for future research. RESULTS: Although stakeholder partners share a common goal of using home-delivered meals as a method to improve outcomes for homebound older adults, individuals have different goals for participating as advisors in this research. CONCLUSIONS: Understanding what individual stakeholders hope to gain from their participation is critical in designing an effective engagement protocol and critical for meaningful and rigorous stakeholder engagement in clinical trials.

Medical care priorities of community-dwelling older adults according to three dimensions of quality of life: Quality of daily living, satisfaction and happiness from birth to death, and human vitality.

AIM: Although the maintenance and improvement of quality of life (QoL) through holistic care are important in geriatric medical care, care priorities might differ depending on three essential aspects of QoL: the quality of daily living, satisfaction and happiness from birth to death, and human vitality, which are "Seikatsu," "Jinsei," "Seimei" in Japanese, respectively. We aimed to clarify these priorities in terms of medical care and examined how the definitions of QoL affected these priorities' rankings. METHODS: This cross-sectional study involved community-dwelling older adults aged ≥65 years living in Kashiwa City, Chiba Prefecture, Japan. The number of participants was 1550 (mean age, 76.1 ± 5.8 years; 699 women [45.1%]). A self-administered questionnaire distributed in advance was used to rank 12 items sought in medical care. Participants were randomly assigned to one of three groups and sent the corresponding questionnaire, which differed only in the definition of QoL. RESULTS: The top priorities for medical care were "effective treatment of illness," "improvement of physical function," and "maintaining a high level of activity." When QoL was defined as "the quality of daily living, satisfaction and happiness from birth to death, and human vitality," participants were significantly more likely to rank QoL improvement as one of the top three items (adjusted odds ratio, 1.46; 95% confidence interval, 1.03-2.05). CONCLUSIONS: As a medical care priority, older adults desire improvement of multidimensional elements of life, including human vitality. Health care providers should consider this when making medical care decisions. Geriatr Gerontol Int 2024; 24: 493-498.

Exploring the impact of information and communication technologies on loneliness and social isolation in community-dwelling older adults: a scoping review of reviews.

BACKGROUND: Recognizing the escalating public health concerns of loneliness and social isolation in aging populations, this study seeks to comprehensively explore the potential of information and communication technology (ICT)-based interventions to address these issues among older adults. This scoping review of reviews aims to map and synthesize existing evidence on the effectiveness and scope of ICT interventions targeting loneliness and social isolation in community-dwelling older adults, elucidating types of technology, impacts, facilitators, barriers, and research gaps. METHODS: Following the Joanna Briggs Institute framework, we systematically searched eight diverse databases identifying relevant published reviews. We included English-written, peer-reviewed reviews of all types, with no limits regarding time of publication about ICTs targeting loneliness and/or social isolation for community-dwelling older adults. Eligible reviews were analysed and summarized, offering a holistic narrative of the reported types of ICTs and their impact, the identified facilitators and barriers influencing the implementation and adoption of ICT interventions, and the research gaps identified in the literature. RESULTS: The review included 39 publications published between 2012 and 2024, spanning systematic, scoping, and reviews of reviews. Various ICTs were reported, primarily social media virtual communities, followed by video-mediated friendly visits, conversational agents, social robots, exergames and online gameplay. Predominantly positive impacts on mitigating social isolation and loneliness were evident for these ICTs, although methodological diversity and contradictory findings complicated definite conclusions. Facilitators and barriers encompassed individual competencies, access and usage, and intervention design and implementation. Research gaps involved targeting specific subgroups, exploring innovative technologies, incorporating diverse study designs, improving research methodologies, and addressing usability and accessibility. Future research should focus on identifying elderly individuals who can benefit the most from ICT use, exploring novel technologies, using a wider range of study designs, and enhancing usability and accessibility considerations. CONCLUSIONS: This review sheds light on the diverse range of ICTs, their impact, and the facilitators and barriers associated with their use. Future investigations should prioritize refining outcome measures, addressing gender differences, and enhancing the usability and accessibility of interventions. The involvement of older adults in the design process and the exploration of technological training interventions hold promise in overcoming barriers.

Measuring patients' medical treatment preferences in advance care planning: development and validation of the Treat-Me-ACP instrument - a secondary analysis of a cluster-randomized controlled trial.

BACKGROUND: Advance Care Planning interventions should be evaluated as broadly as possible to gain a holistic understanding of the Advance Care Planning process. However, validated early stage outcome instruments are lacking. Therefore, the Treatment-Preference-Measure-Advance Care Planning (Treat-Me-ACP) instrument was developed and validated as part of the cluster-randomized controlled trial STADPLAN (Study on Advance Care Planning in care-dependent community-dwelling older persons) to assess the effects of Advance Care Planning interventions on patients' medical treatment preferences. METHODS: The design of Treat-Me-ACP is based on the Emanuel Medical Directive and the Life Support Preferences Questionnaires. Using a multi-stage team approach a preliminary version of the Treat-Me-ACP was developed and pre-tested. The pre-tested instrument consists of one global medical care goal-item, five hypothetical scenarios with five hypothetical treatments, and one how would you feel-item within each scenario. A total of five scenario preference scores and five treatment preference scores can be formed. This version was subsequently applied to a subsample of the STADPLAN project (n = 80) to assess patient's preferences at baseline (T0) and at 12-month follow-up (T2). The further validation steps were based on this subsample and included: (1) acceptance by using completion rate and frequencies of missing data, (2) internal consistency by using Cronbach's α to test whether it was possible to create preference scores by scenario and treatment, (3) concurrent validation examining the association between the global medical care goal-item and the preference scores and the association between the how would you feel-items and the scenario preference scores, and (4) responsiveness of the instrument to changes in preferences for life-sustaining treatments by comparing preference scores from T0 to T2 between study groups. RESULTS: Acceptance of the instrument was high. Results of concurrent validation indicate that the five scenarios represent the global medical care goal well. The preference scores showed an average tendency for decreasing preferences for life-sustaining treatments across all scales for the intervention group during study follow-up. CONCLUSIONS: The Treat-Me-ACP can be used to evaluate the dynamics of patients' medical treatment preferences in Advance Care Planning. It has been validated for care-dependent community-dwelling older persons and can be used as an additional outcome measure in evaluating the effectiveness of ACP interventions.

Vitamin K1 intake is associated with lower risk for all-cause and cardiovascular disease mortality in community-dwelling older Australian women.

BACKGROUND AND AIMS: Assessing the relationship between vitamin K1 intakes, using region-specific food databases, with both all-cause, and cardiovascular disease (CVD) mortality warrants further investigation to inform future preventative strategies. Consequently, we examined the aforementioned associations in the Perth Longitudinal Study of Ageing Women (PLSAW). METHODS AND RESULTS: 1436 community-dwelling older Australian women (mean ± SD age 75.2 ± 2.7 years) completed a validated food frequency questionnaire at baseline (1998). Vitamin K1 intake was calculated based on an Australian vitamin K food database, supplemented with published data. All-cause and CVD mortality data was obtained from linked health records. Associations were examined using restricted cubic splines within Cox-proportional hazard models, adjusted for a range of cardiovascular and lifestyle related risk factors. Over 15 years of follow-up, 601 (41.9%) women died, with 236 deaths (16.4%) due to CVD. Compared to women with the lowest vitamin K1 intakes (Quartile 1, median 49.1 µg/day), those with the highest intakes (Quartile 4, median 119.3 µg/day) had lower relative hazards for all-cause mortality (HR 0.66 95%CI 0.51-0.86) and CVD mortality (HR 0.61 95%CI 0.41-0.92). A plateau in the inverse association was observed from vitamin K1 intakes of approximately ≥80 µg/day. CONCLUSION: Higher vitamin K1 intakes were associated with lower risk for both all-cause and CVD mortality in community-dwelling older women, independent of CVD related risk factors. A higher intake of vitamin K1 rich foods, such as leafy green vegetables, may support cardiovascular health.

A Judo-Based Exercise Program to Reduce Falls and Frailty Risk in Community-Dwelling Older Adults: A Feasibility Study.

OBJECTIVES: This study aimed to explore the feasibility (including recruitment, safety and adherence) and the effects of a twice weekly supervised Judo-based exercise program over eight weeks on mobility, balance, physical performance, quality of life, fear of falling and physical activity (including by frailty status) in community-dwelling older people aged ≥65 years. DESIGN: Pre-post study. PARTICIPANTS: A total of 17 participants (mean age 74.3±6.2; range 66-87 years; 76.5% female). INTERVENTION: A Judo-based exercise program conducted twice weekly for 60 minutes per session over eight weeks. MEASUREMENTS: Pre and post assessments included the Timed Up and Go (TUG); the Berg Balance Scale (BBS); the Short Physical Performance Battery (SPPB); the Short Form Health Survey-36 (SF-36); the Falls Efficiency Scale International (FES-I); and an ActivPal accelerometer to measure participants' physical activity. RESULTS: Most participants had low (≤3) Charlson's Comorbidity Index scores (n=17, 100%), were well nourished (n=16, 94.1%), not sarcopenic (n=16, 94.1%), and not cognitively impaired (n=13, 76.5%), anxious or depressed (n=14, 82.4%). Ten participants (58.8%) were non-frail and seven were pre-frail (41.2%). Significant improvements (p<0.05) were seen for mobility (TUG), balance (BBS) and physical performance (SPPB). Pre-frail participants showed greater improvement in mobility (TUG) than non-frail participants (p=0.020). No changes (p≥0.05) were seen in quality of life, fear of falling, or physical activity. Participants' adherence (i.e., attending sessions) was high (i.e., ≥81.2%). No serious adverse events or withdrawals were reported. CONCLUSION: Findings suggest that the eight week Judo-based exercise program can be delivered safely to older adults aged ≥65 years, including those at-risk of frailty, as long as there is close supervision with individualisation of the program in response to emergent health symptoms and the program is conducted on requisite Judo mats. This Judo-based exercise program is effective in improving physical function with potential to prevent falls and frailty risk.

Effects of resistance training and nutritional support on osteosarcopenia in older, community-dwelling postmenopausal Korean females (ERTO-K study): a study protocol.

BACKGROUND: Osteosarcopenia is geriatric syndrome defined as the concomitant occurrence of osteopenia/osteoporosis, and sarcopenia. Osteosarcopenia is a relatively new concept in geriatric medicine; however, it may increase the risk of fragility fractures, several morbidities and mortalities, and socioeconomic costs. Although resistance exercises and nutritional support-including protein, calcium, and vitamin D-are potential non-pharmacological management procedures, evidence is still lacking. The objective of this study was therefore to evaluate the effect of combined resistance exercise and nutritional support on the quality and quantity of bone and muscle in postmenopausal females with osteosarcopenia. METHODS: This research proposal presents the protocol for a prospective, single-center, single-blinded, two-armed randomized controlled trial. Thirty-four participants with osteosarcopenia will be recruited and randomly divided into intervention and control groups; both groups will receive nutritional supplements (protein, 40 g; vitamin D, 1600 IU; calcium, 600 mg) daily. The intervention group will undergo 24 weeks of resistance exercise of increasing intensity, achieved through a three-phase step-up process. The primary outcomes will be the changes in skeletal muscle index and bone marrow density of the lumbar spine and femoral neck between the baseline and end of intervention (24 weeks). The secondary outcomes will be the body composition, whole body phase angle, physical function assessment, quality of life, psychological assessment, and bone turnover markers of participants, surveyed at multiple time points. DISCUSSION: This randomized controlled trial may reveal the effect of resistance exercise and nutritional support on older postmenopausal women with osteosarcopenia. The results will provide evidence for developing proper non-pharmacological management guidelines for postmenopausal women.

Association between vitamin D status, physical performance, sex, and lifestyle factors: a cross-sectional study of community-dwelling Kosovar adults aged 40 years and older.

PURPOSE: Vitamin D status and its association with age-related decline in physical performance and strength have already been highlighted in various ways, but data on the situation in developing countries are scarce. This study aimed to investigate vitamin D status, its association with muscle mass and function, and other potential determinants such as age, sex, lifestyle factors (physical activity, dietary behavior), self-perceived health status, medication intake, education and financial situation in adults from Kosovo. METHODS: This cross-sectional study included 297 participants (54.5% women), aged ≥ 40 years. Serum 25-hydroxyvitamin D (25(OH)D) concentration, hand grip strength and physical performance tests, body composition, vitamin D dietary intake and knowledge were assessed. The interaction between serum 25(OH)D status, lifestyle factors and muscle traits was investigated. RESULTS: Vitamin D deficiency (< 50 nmol/L) was observed in 47.5% of the total population, of whom 14.7% of them were severely deficient (< 30 nmol/L). No associations were found between 25(OH)D concentration and age. Daily dietary intake of vitamin D was low (1.89 ± 0.67 µg) and 87.6% of individuals did not take vitamin D supplements. However, vitamin D supplementation was the only variable that added statistical significance (p < 0.05) to the prediction of vitamin D status (3.8%). On the other hand, age, medication intake and vitamin D level contributed significantly to the overall regression model, explaining 24.9% of the 30-s chair stand performance as an indicator of lower-body strength endurance. CONCLUSION: Vitamin D deficiency is highly prevalent among community-dwelling adults in Kosovo and low serum 25(OH)D has been associated with low muscle strength. This implies an urgent need for the development of comprehensive prevention strategies, focusing on pharmacological (supplementation) but also on non-pharmacological strategies such as education, food fortification or lifestyle advices.

Association between endogenous plasma beta-hydroxy-beta-methylbutyrate levels and frailty in community-dwelling older people.

BACKGROUND: Frailty is a key element in healthy ageing in which muscle performance plays a main role. Beta-hydroxy-beta-methylbutyrate (HMB) supplementation has shown favourable effects in modulating protein synthesis, improving muscle mass and function in interventional studies. Decreased age-related endogenous HMB levels have been shown in previous studies. The aim of the present study is to assess whether there is an association between endogenous plasma HMB levels and frailty. METHODS: Data from 1290 subjects (56.98% women; mean ± standard deviation age 74.6 ± 5.95 years) from the Toledo Study for Healthy Aging were obtained. Participants had their frailty status qualified according to Fried's Frailty Phenotype (FFP) score and the Frailty Trait Scale in its 12-domain version (FTS-12). Plasma HMB levels were analysed by an ultrahigh-performance liquid chromatography tandem mass spectrometry. Differences between groups (frail vs. non-frail) were tested using Mann-Whitney U test, Kruskal-Wallis test and chi-squared test. The association between HMB and frailty was assessed by multivariate linear and logistic regressions when frailty was analysed as continuous and binary, respectively. Models were adjusted by age, gender, comorbidity, body composition and protein intake. RESULTS: HMB levels were lower in those aged ≥75 years than in those aged 65-74 years, with an inverse linear relationship between age and HMB levels (ß = -0.031; P = 0.018), mainly accounted by males (ß = -0.062; P = 0.002). HMB levels were higher in men (0.238 ± 0.065 vs. 0.193 ± 0.051 ng/mL; P ≤ 0.001). HMB levels were significantly lower in frail than in non-frail individuals: 0.204 ± 0.058 versus 0.217 ± 0.063 ng/dL (P = 0.001) according to the FFP and 0.203 ± 0.059 versus 0.219 ± 0.063 ng/mL (P < 0.001) according to FTS-12. These differences showed a dose-dependent profile when we compared them by quintiles of HMB (P for trend: 0.022; 0.012 and 0.0004, respectively, for FFP, FTS-12 binary and FTS-12 continuous). Variables associated with low HMB levels were body mass index, strength, exhaustion and weight loss. Frailty was associated with HMB levels in all the adjusted models, including the fully adjusted ones, no matter the tool used (odds ratio: 0.45 [0.26, 0.77] for FFP and 0.36 [0.20, 0.63] for FTS-12 binary; ß = -4.76 [-7.29, -2.23] for FTS-12 score). This association was also observed when the analyses were done by quintiles, showing such association since Q4 (FFP), Q2 (FTS-12 binary) and Q3 (FTS-12 score). The associations were observed in the whole sample and in each gender. CONCLUSIONS: There is an inverse association between HMB levels and frailty status. These findings support the design of targeted clinical trials to evaluate the effect of HMB supplementation in older frail people with low HMB levels.

The Association Between Habitual Tea Consumption and Frailty Transition in Community-Dwelling Older Adults: A Prospective Cohort Study.

OBJECTIVES: To investigate the association between habitual tea consumption and transitions between frailty states among older adults in China. DESIGN: A prospective cohort study based on the Chinese Longitudinal Healthy Longevity Study. SETTING AND PARTICIPANTS: A total of 23,720 older adults aged ≥65 years with complete data regarding frailty status and tea consumption were recruited. METHODS: The frequency and consistency of tea consumption were introduced to evaluate levels of tea consumption. The frailty index was used to define frailty status (frail and nonfrail). Frailty transition was classified into remaining nonfrail, improvement, worsening, and remaining frail groups. Logistic regression models were applied. RESULTS: The overall frailty prevalence at baseline was 19.1%, being lower among consistent daily tea drinkers (12.5%) and higher among non-tea drinkers (21.9%). Logistic regression analyses showed that the risk of frailty was significantly reduced among consistent daily tea drinkers after adjusting for all confounders [odds ratio (OR), 0.81; 95% CI, 0.67-0.98]. During the 3-year follow-up, improvement in frailty status was more common among consistent daily tea drinkers (50.9%) than non-tea drinkers (40.9%), and this trend was opposite in participants with worsened frailty status (consistent daily tea drinkers: 12.2%) vs non-tea drinkers: 19.2%). Further analysis showed that consistent daily tea drinkers were significantly associated with improvement in frailty status (OR, 3.24; 95% CI, 1.02-10.31) and remaining in a nonfrail state (OR, 1.35; 95% CI, 1.00-1.83). In addition, daily tea consumption was observed to be positively associated with remaining in a nonfrail state and inversely associated with worsened frailty status in men, but not in women. CONCLUSIONS AND IMPLICATIONS: Older people consuming tea daily tend to have an improved frailty status in the future. Men with daily tea consumption were less likely to have a worsened frailty status. Advocating for the traditional lifestyle of drinking tea could be a promising way to advance healthy aging for older adults.

Understanding the home environment of older adults living with dementia: A scoping review of assessment tools.

Rigorous assessments to better understand the person-environment interaction are essential to comprehend how neurocognitive disorders influence in-home functioning of older people living with dementia. No recent synthesis identifies validated instruments targeting the human (e.g. caregivers) and nonhuman (e.g. objects) elements of the home environment interacting with this population and used with the perspective of aging in place. Consequently, following Arksey and O'Malley's (2005) scoping review method, 2,182 articles were identified in six databases and in gray literature. Two reviewers independently selected 23 relevant articles describing 19 validated assessment tools targeting elements of the home interacting with older people with dementia, namely: nonhuman environment (n = 13), human environment (n = 3), and person-environment interaction (n = 3). This overview highlights the scarcity of tools addressing the human environment and the person-environment interaction to foster sustainable at-home living for older people with neurocognitive disorders, demonstrating the need to incorporate new evidence-based, holistic methods into dementia home care.

How is complexity measured and detected among community dwelling older people aged 65 years and over? A scoping review.

AIM: To identify and explore tools that measured and detected complexity of care among community dwelling people aged 65 years and older. DATA SOURCES: Databases were searched for articles published up to 23 September 2022 including CINAHL, EMBASE and MEDLINE, Cochrane database for trials and grey literature. METHODS: A scoping review was conducted and reported in accordance with the PRISMA guidelines. Eligible articles included those with participants aged over 65 years, living in the community and studies that included care complexity detection or assessment and how this related to care delivered. Covidence was used to screen titles, abstracts and full-text articles. RESULTS: Eighteen full texts were reviewed; four studies were included in the final review. All selected studies included people aged over 65 years living in the community. A high level of reliability for the items included in the interventions was found. The selected studies included tools for assessing older person's needs with nurses involved in the assessment. CONCLUSION: The review identified four tools for measuring complexity in community dwelling older people. Two tools have the capacity to objectively measure complexity due to the holistic nature of items included and appear easy to use to support clinical judgement decisions. IMPACT: The review places a spotlight on the concept of complexity and highlights the lack of definition of care complexity. The synthesized result highlights the need to explore detection of care complexity of older people further and consider ways of supporting clinical judgement and decision making of community nurses. The use of a validated tool may enhance clinical judgement regarding care complexity and may lead to a more consistent and timely approach to care. PATIENT OR PUBLIC CONTRIBUTION: During the development phase, the study was presented to a consumer group from the researcher's workplace. PROSPERO REGISTRATION: CRD42022299336.

Sweet-type star fruit supplementation controls oxidative stress status and enhances the community walking capacity among elderly Thai.

BACKGROUND: Sweet-type Star fruit (SF) (Averrhoa carambola L.) is seasonal and more available for purchase in many markets in Thailand, when compared to the sour-type. But, its antioxidant activity results and potentially more modified supplement for elderly health during regular exercise in the community are unclear. OBJECTIVE: This study aimed to evaluate the antioxidant activity and physical capacity from supplementation of sweet-type SF among elderly people performing home walking exercise. METHODS: Mixing SF juice with honey industrially prepared the SF product. Its effects on oxidative stress status and physical capacity were studied in four groups; a supplement with walking exercise (n = 11, 67.00 ± 4.17 years), control (n = 12, aged 67.50 ± 5.58 years), supplementation (n = 11, aged 69.63 ± 7.14 years), and walking exercise (n = 12, aged 67.91 ± 4.33 years). Twenty grams or two teaspoons of supplement in warm water (150 mL) was the guideline for consumption twice daily for 4 weeks. In contrast, the walking exercise was prescribed with moderate intensity for 30 min, 3 days per week. Before and after the 4-week period, the oxidative stress status; glutathione (GSH), ascorbic acid (Vit C), total antioxidant capacity (TAC), and malondialdehyde (MDA), and 6-minute walking distance (6MWD) were evaluated. RESULTS: Results after the 4-week period, showed that Vit C and TAC increased and the MDA decreased significantly in the supplementation group, except the GSH and 6MWD results. The GSH and Vit C slightly decreased in the walking exercise group, whereas, its TAC, MDA and 6MWD increased significantly. Finally, The GSH and Vit C did not decrease and MDA slightly decreased in the combined group, but, their TAC and 6MWD increased significantly. CONCLUSION: Supplementation of the SF product during walking exercise possibly controls oxidative stress status and may enhance walking capacity.

Association between dietary antioxidant and fatty acids and low muscle mass in obese and non-obese community-dwelling older adults: An NHANES analysis.

Sarcopenia increases disability, hospital stays, readmissions, and mortality in older adults. Antioxidative nutrients and fatty acids consumption may help maintain muscle mass by reducing oxidative stress. This study aims to assess the association between antioxidant and fatty acid intake and low muscle mass in community-dwelling older people. This retrospective analysis used data from the National Health and Nutrition Examination Survey from 1999 to 2004. Participants ≥ 60 years with information on muscle mass measured by Dual energy X-ray absorptiometry (DXA) were included. Appendicular skeletal muscle mass was assessed. Associations between antioxidants and fatty acids intake, and low muscle mass were evaluated using logistic regressions. 3648 (1748 men and 1900 women) were included. The prevalence of low muscle mass was 41% and 26% among men and women ≥ 75 years, and 45.2% and 28.4% among obese men and women. In obese males, a natural-log-unit increase of vitamin A (aOR = 0.806, 95% CI: 0.652-0.996), vitamin C (aOR = 0.878, 95% CI: 0.779-0.990), selenium intake (aOR = 0.716, 95% CI: 0.517-0.993), and higher saturated fatty acids (aOR = 0.956, 95% CI: 0.915-0.998) and monounsaturated fatty acids (aOR = 0.959, 95% CI: 0.925-0.994) intake were associated with decreased odds for low muscle mass. Among obese females, a natural-log-unit increase of vitamin E (P = .036), vitamin B12 (P = .014), total folate (P = .015), zinc (P = .005), and selenium intake (P = .018) were associated with increased odds of low muscle mass, whereas higher saturated fatty acids (P < .001), monounsaturated fatty acids (P = .001), and polyunsaturated fatty acids intake (P = .006) were associated with decreased odds for low muscle mass. Antioxidants (vitamin A, C, E, B6, B12, total folate, zinc, magnesium, selenium) intake does not consistently relate to low muscle mass across age and sex. Higher intake of saturated, monounsaturated, and polyunsaturated fatty acids are independently associated with reduced likelihood of low muscle mass in both obese older men and women.

Predictors of Sleep Quality in Spouse Caregivers of Community-Dwelling People With Dementia Using Propensity Score Matching Analysis.

BACKGROUND: Many family caregivers of people with dementia (PwDs) have sleep problems and poor sleep quality. Sleep may be negatively affected by caring for a family member with dementia, especially a spouse. PURPOSE: This study was designed to assess sleep quality in spouse caregivers of PwDs and determine the impact of care provision on their sleep quality. METHODS: A secondary analysis of 58,050 participants in the 2018 Korea Community Health Survey was conducted. To prevent selection bias, a propensity score matching analysis was performed. Multiple logistic regression analysis was conducted to investigate the predictors of sleep quality. RESULTS: After obtaining a propensity score matching threshold of 3:1, the percentage of poor sleepers was 24.2% in the control group and 33.3% in the spouse-caregiver group, which indicates a significant difference (χ 2 = 11.79, p = .001). After adjusting for depressive symptoms in the multiple logistic analyses, no intergroup difference was found in terms of risk of poor sleep quality (odds ratio = 1.12, 95% CI [0.90, 1.61]). CONCLUSIONS/IMPLICATIONS FOR PRACTICE: The findings of this study support that spouse caregivers of PwDs have poorer sleep quality than their nonspouse peers and that management of depressive symptoms is important to improving the sleep quality of spouses providing care to PwDs. Nursing interventions such as light therapy and exposure to sunlight during daytime hours to both improve sleep quality and reduce depressive symptoms can improve sleep quality in this vulnerable caregiver group.

Discordance in Frailty Measures in Old Community Dwelling People with Multimorbidity - A Cross-Sectional Study.

Purpose: Assessment of frailty is a key method to identify older people in need of holistic care. However, agreement between different frailty instrument varies. Thus, groups classified as frail by different instruments are not completely overlapping. This study evaluated differences in sociodemographic factors, cognition, functional status, and quality of life between older persons with multimorbidity who were discordantly classified by five different frailty instruments, with focus on the Clinical Frailty Scale (CFS) and Fried's Frailty Phenotype (FP). Participants and Methods: This was a cross-sectional study in a community-dwelling setting. Inclusion criteria were as follows: ≥75 years old, ≥3 visits to the emergency department the past 18 months, and ≥3 diagnoses according to ICD-10. 450 participants were included. Frailty was assessed by CFS, FP, Short Physical Performance Battery (SPPB), Grip Strength and Walking Speed. Results: 385 participants had data on all frailty instruments. Prevalence of frailty ranged from 34% (CFS) to 75% (SPPB). Nine percent of participants were non-frail by all instruments, 20% were frail by all instruments and 71% had discordant frailty classifications. Those who were frail according to CFS but not by the other instruments had lower cognition and functional status. Those who were frail according to FP but not CFS were, to a larger extent, women, lived alone, had higher cognitive ability and functional status. Conclusion: The CFS might not identify physically frail women in older community-dwelling people with multimorbidity. They could thus be at risk of not be given the attention their frail condition need.

Addition of community paramedics to a physician home-visit program: A prospective cohort study.

BACKGROUND: Home-based primary care promotes aging in place but is not immediately responsive to urgent needs. Community paramedicine leverages emergency medical services clinicians to expedite in-home care, though limited evidence supports this model. We evaluated the primary care and acute care use of older adults evaluated urgently by a community paramedic with telemedicine physician compared to a physician home visit model. METHODS: This prospective cohort study enrolled older adults in home-based primary care who requested an urgent evaluation. We allocated participants to the physician home visit model or physician home visit plus community paramedic model by ZIP code. We observed primary care and acute care use for 6 months following enrollment. The primary outcome was the median number of primary care and acute care visits per participant. Secondary outcomes included 30-day readmission rates, median wait times, and physician productivity. Data analysis included descriptive statistics, comparison of means and proportions, and negative binomial regression modeling reported as incidence rate ratios (IRR). RESULTS: We screened 255 participants, determined 203 eligible, allocated 199, and completed observation for 167 (84 community paramedicine, 83 physician home visit). Participants were mostly female, age 76-86 years, with 3-5 comorbidities, living in a home/apartment. Community paramedic participants had 29% more primary care visits (IRR 1.29, 95% confidence interval [CI] 1.06-1.57) and shorter wait times for urgent evaluations (1 vs. 5 days, p < 0.001) without increasing acute care use (IRR 0.75, 95% CI 0.48-1.18) or 30-day readmissions (IRR 1.32, 95% CI 0.49-3.55). Physician productivity increased 81% (40 vs. 22 visits/week, p < 0.001). CONCLUSION: Older adults evaluated by a community paramedic for urgent needs were seen sooner, used acute care similarly to patients evaluated by a physician home visit, and nearly doubled physician efficiency. This suggests that older adults may benefit from combining emergency medical services and primary care resources for urgent evaluations.

Implementation and Core Components of a Multimodal Program including Exercise and Nutrition in Prevention and Treatment of Frailty in Community-Dwelling Older Adults: A Narrative Review.

Increasing disability-free life expectancy is a crucial issue to optimize active ageing and to reduce the burden of evitable medical costs. One of the main challenges is to develop pragmatic and personalized prevention strategies in order to prevent frailty, counteract adverse outcomes such as falls and mobility disability, and to improve quality of life. Strong evidence reports the effectiveness of exercise interventions to improve various physical parameters and muscle function that are cornerstones of frailty. Other findings also suggest that the interactions between nutrition and physical exercise with or without health behavior promotion prevent the development of frailty. Multimodal programs, including structured exercise, adequate dietary intervention and health behavior promotion, appear increasingly consensual. However, in order for implementation in real-life settings, some pitfalls need to be addressed. In this perspective, structuring and tailoring feasible, acceptable and sustainable interventions to optimize exercise training responses are essential conditions to warrant short, medium and long-term individual benefits. The different components of exercise programs appear to be fairly consensual and effective. However, specific composition of the programs proposed (frequency, intensity, type, time, volume and progressiveness) have to be tailored to individual characteristics and objectives in order to improve exercise responses. The intervention approaches, behavioral strategies and indications for these programs also need to be refined and framed. The main objective of this work is to guide the actions of healthcare professionals and enable them to widely and effectively implement multimodal programs including exercise, nutrition and behavioral strategies in real-life settings.
