Factors and prediction model associated with resumption of social outings in stroke survivors 6 months after onset: a multicenter prospective study

ABSTRACT Objectives To identify factors associated with the resumption of social outings 6 months after stroke onset and develop a simple clinically practical prediction model. Materials and methods Participants were recruited from first-ever stroke survivors admitted to three rehabilitation wards, and resumption of social outings 6 months after stroke onset was assessed using the Japanese version of the Frenchay Activities Index. The association of physical and cognitive functions with activities of daily living at admission to the rehabilitation ward and resumption of social outings 6 months after stroke onset was examined using logistic regression and decision trees. Results Notably, 63.2% of the 57 stroke survivors who participated in this study had lower Frenchay Activities Index scores for social outings 6 months after stroke onset than before. Logistic regression analysis revealed that attention deficit and grooming on the Functional Independence Measure (FIMTM) were significantly associated with decreased social outing scores 6 months after stroke onset. A decision tree model was created to predict the resumption of social outings using the presence or absence of attention disorders and FIMTM grooming score (>2 or ≤ 2). Conclusions The results of this study suggest that attention deficit and beyond a certain level of independence in grooming (FIMTM >2) at admission to the rehabilitation ward are associated with recovery to the pre-stroke level of social outings 6 months after stroke onset. The decision tree created in this study holds promise as a simple model to predict the resumption of social outings among stroke survivors.

Cognitive frailty in older adults: examining the impact of frailty criteria on neuropsychological profile, functional outcomes, activity levels, and quality of life.

Cognitive frailty (CF) is the co-existence of cognitive impairment and physical frailty without dementia, conferring greater risks of adverse clinical outcomes compared to either condition alone. However, the impact of physical frailty components on cognitive performance remains unclear. This study aims to evaluate CF by determining the neuropsychological profiles, functional outcomes, activity levels, and quality of life across the Fried Frailty Phenotype (FFP) and its components. Cross-sectional study involving 120 community-dwelling older adults without dementia, but with subjective cognitive complaints (SCC, defined as AD8 ≥ 1). Participants were stratified into three groups to assess CF: SCC-Robust, SCC-Prefrail, and SCC-Frail, and further categorized by individual FFP components. Cognitive performance was assessed by comparing neuropsychological test battery (NTB) Z-scores between CF and non-CF groups with Cohen's d for effect sizes. We performed linear regression to examine the relationships between both groups with NTB scores, Instrumental Activities of Daily Living (IADL), Frenchay Activities Index (FAI), and quality of life scores. NTB scores showed no differences between individuals with CF when classified according to FFP criteria. Individuals with SCC-slow gait speed exhibited reduced processing speed (d = 0.62) and memory (d = 0.61); SCC-fatigue was associated with decreased working memory (d = 0.55). Regression analyses, adjusted for demographic and clinical variables, identified significant associations: slow gait speed with logical memory (-0.42; 95% CI -0.79 to -0.038]) and symbol search (-0.28; 95% CI -0.56 to -0.006]); fatigue with digit span backwards (-0.66; 95% CI -1.19 to -0.14) and color trails 2 (-0.67; 95% CI, -1.15 to -0.20). SCC-slow gait speed and SCC-fatigue were associated with reduced quality of life scores, but not with IADL and FAI scores. Specific frailty components, notably slow gait speed and fatigue, influence cognitive function and quality of life. Our findings provide greater insights into characterizing CF. Further longitudinal studies are required to determine the cognitive and functional trajectories of CF.

Effect of Early Rehabilitation Services After Discharge on Social Activity Among Chronic Stroke Survivors: A Multicenter Prospective Study

BackgroundSocial inactivity after a stroke leads to adverse outcomes, making social activity after discharge important for chronic stroke survivors. ObjectivesTo investigate the effects of early rehabilitation services after discharge on social activity among chronic stroke survivors. MethodsThe participants were prospectively recruited from three convalescent hospitals. Receipt of early rehabilitation services after discharge for chronic stroke survivors was defined as the utilization of day care or home-based rehabilitation services by the Japanese long-term care insurance system. Social activity was assessed using the Frenchay Activities Index (FAI) premorbid and at 3, 6, and 12 months after discharge. In this study, the outcome was defined as the change in the FAI score from 3 to 12 months after discharge. Multivariate regression analysis was performed to examine the effect of access to rehabilitation on changes in FAI. ResultsNinety stroke survivors (age 67.2 ± 11.6 years, 52 male) were enrolled. The FAI showed improvements by 27.4% and 1.4% from 3 to 12 months after discharge in the rehabilitation and non-rehabilitation groups, respectively. Multivariate regression analysis showed that access to rehabilitation after discharge was positively associated with the FAI change from 3 to 12 months after discharge (B = 30.3, β = 0.38, 95% confidence interval = 11.13–49.47, p = 0.002). ConclusionEarly rehabilitation services after discharge were significantly associated with increased social activity.

Investigation of the effect of task-oriented occupational therapy on daily living activity performance in chronic stroke patients.

Task-oriented therapy (TOT) is used to increase the effectiveness of upper extremity (UE) in activity daily living (ADL). This study aimed to investigate the effect of TOT on the participation and ADLs of stroke patients. Between October 2018 and February 2019, 28 chronic stroke patients were included in the study treated in Kocaeli University Hospital, Department of Physical Medicine and Rehabilitation, Turkey. The performance areas and participation status of the patients in which they experienced limitations were evaluated with the Canadian Occupational Performance Scale (COPM), and their level of independence in ADLs was evaluated with the Modified Frenchay Activity Index (mFAI) and Barthel Index (BI). All patients were included in the occupational therapy (OT) program five days a week for three weeks at Kocaeli University Hospital. Three ADLs in which they had difficulties were studied with 28 patients. Each of the activities was designed specifically for the patient. All assessments were repeated after three weeks of treatment. A total of 28 patients, 12 females and 16 males, diagnosed with stroke, were included in the study. A statistically significant increase was found in the COPM performance and satisfaction value compared to the pre-treatment value (p<0.001). A statistically significant difference was found between pre- and post-treatment mFAI and BI values (p<0.001). Adding task-oriented therapy to the rehabilitation programs of stroke patients will contribute to the improvement of ADL.

Comparing the efficacy of a multi-dimensional breast cancer rehabilitation programme versus a home-based exercise programme during adjuvant cancer treatment

BackgroundBreast cancer is the most common female malignancy worldwide and a major cause of morbidity and mortality. Exercise during adjuvant treatment improves function and relieves symptoms in breast cancer survivors. However, it is unclear if an unsupervised exercise programme may be as effective as a supervised multimodal group. We investigated the feasibility and efficacy of a centre-based multidimensional rehabilitation (MDR) programme for breast cancer survivors undergoing adjuvant treatment and compared it to an unsupervised home-based exercise (HE) programme.MethodsParticipants were self-allocated to either MDR or HE group. MDR participants underwent 24 supervised exercise classes and 10 education classes over 12 weeks. HE participants were instructed on a home exercise regime. Outcome measures, including the 6-min walk test (6MWT) and Frenchay Activities Index (FAI), FACT-Cognitive Function scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, were conducted at baseline (W0), post-intervention (W12) and 6-months post-intervention (M6). Variance between time points and the 2 groups were analysed using a linear mixed model (unstructured covariance matrix) and adjusted with Bonferroni.ResultTwenty-five participants attended at least half of the MDR interventions, while 21 completed the HE interventions. The former showed significant improvement in 6MWT, from 406.88 m (W0) to 443.34 m (W12) to 452.81 m (M6), while the improvement in the HE group was not significant (407.67 m (W0) to 433.14 m (W12) to 430.96 m (M6)). Both groups showed a significant improvement in FAI, with earlier significant improvement noted at W12 in the MDR group (22.71 (W0) to 27.65 (W12) to 28.81 (M6)) compared to the HE group (23.16 (W0) to 26.47 (W12) to 29.85 (M6)). Dropout rate was 16% in the MDR group and 34% in HE group. Overall satisfaction with the MDR programme was high.ConclusionBoth MDR and HE programmes were feasible. MDR was superior in improving endurance and earlier return to instrumental activities for those who completed at least half of the sessions. Future studies could explore use of technology to improve adherence to exercise.Trial registrationThe study was registered with ClinicalTrial.gov on 01/04/2022 with the registration number NCT05306808.

Factors Related to Favorable Outcomes in Older Adults Undergoing Home-Visit Rehabilitation Therapy.

Increasing elderly population is a major health concern worldwide, requiring various at-home care services. The aim of home-visit rehabilitation therapy is to support at-home living of the elderly and to promote their participation in social activities. There is a paucity of data about the clinical conditions of this population that can contribute to the achievement of goals in-home visit rehabilitation therapy. This study aimed to clarify clinical variables that could be related to the achievement of goals in-home visit rehabilitation therapy. We collected retrospective clinical data of the older adults who underwent home-visit rehabilitation therapy between July 2006 and June 2021. We searched the clinical variables of home-visit rehabilitation therapy users and their frequency of utilization of home-visit rehabilitation therapy services from the clinical record. The initial and final clinical variables evaluated in this study included the abilities of daily living, degree of being bedridden, dementia rating, and levels of support or long-term care. Those variables were evaluated by rehabilitation therapists and doctors. The users were divided into three groups according to the reason for terminating rehabilitation therapy: goal achievement (achieved group), aggravation of underlying disease (aggravated group),and treatment suspension because of their own/others' wish (suspended group). The clinical parameters concerning the rehabilitation program, care level, and activities of daily living were evaluated among the groups. The clinical parameters concerning the rehabilitation program, care level, and activities of daily living were statistically evaluated among those three groups, using the chi-square test and Kruskal-Wallis test. In the achieved, aggravated, and suspended groups, 45, 190, and 38 users were respectively enrolled. The aggravated group showed significantly higher finalcare level (p = 0.002), degree of being bedridden (p=0.001), and dementia rating (p = 0.017) and significantly lower Barthel index scores (p < 0.001) and Frenchay Activities Index scores (p = 0.001) than the achieved group. Persons requesting the therapy were significantly older adults themselves in the achieved group (p = 0.018). The therapy was significantly performed more than once per week in the achieved group (p = 0.018). Older adults undergoing self-motivated home-visit rehabilitation therapy more than once per week may contribute to the achievement of the goal.

Frequency of instrumental activities of daily living is associated with objectively measured physical activity in stable patients with cardiovascular disease

Abstract Introduction Implementation of instrumental activities of daily living (IADL) has the necessary items for independent living in community-dwelling, which is reported as a relevant factor for better prognosis in patients with cardiovascular disease (CVD). Physical activity (PA) is well-known to have benefits in reducing the risk of all-cause mortality and CVD. Although IADL and PA are similar behaviors and crucial intervention targets to prevent the recurrences of CVD in patients who participate in phase III cardiac rehabilitation, these interrelations remain unclear. Purpose This study aimed to evaluate the association between IADL frequency and objectively measured PA, including step counts and time of vigorous activity, in stable patients with CVD. Additionally, we examined whether detailed types of IADL frequency were associated with PA. Methods This was a single-center cross-sectional observational study. We included patients with CVD who received outpatient care with stable condition for at least six months. Participants completed Frenchay Activities Index (FAI) questionnaire as an assessment of IADL frequency. The FAI contains 15 items, classified as housework and leisure activity. We used accelerometers to measure the objective number of steps and minutes of moderate to high-intensity physical activities for two weeks and calculated their averages per day as indicators of PA levels. The associations of FAI total score and 15 FAI sub-items with physical activities (the number of steps and minutes of moderate to high-intensity physical activities per day) were analyzed using a multivariate linear regression model. Results Studied patients consisted of 1126 stable patients with CVD (mean age, 72.6 ± 10.0 years; 848 males). After adjusting for clinical confounding factors, high FAI total score was significantly associated with higher levels of physical activities (the number of steps per day: unstandardized coefficient [В] for FAI increase of 1 point = 78.1 [95% confidence interval {CI}, 54.9–101.4], Figure 1-A; the minute of moderate to high-intensity PA per day: В = 0.184 [95%CI, 0.063–0.304], Figure 1-B). In the sub-items of FAI, four items of housework activities (washing up, light housework, heavy housework, and local shopping) and six items of leisure activity (walking outside for &amp;gt; 15 minutes, actively pursuing hobbies, driving a car or bus travel, gardening, reading books and gainful work) were also positively associated with the number of steps per day. Conversely, only two items of leisure activity (walking outside and actively pursuing hobbies) were associated with moderate to high-intensity PA per day (Figure 2). Conclusions The frequency of IADL has a positive association with objectively measured PA, suggesting that IADL might be useful behavior to administrate PA in stable patients with CVD. Moreover, leisure activity in IADL is especially relevant to vigorous PA in these patients.Figure 1Figure 2

Post-stroke limitations in daily activities: experience from a tertiary care hospital in Ethiopia

BackgroundThe disability of stroke patients remains an important global health problem; yet information on the extent of restriction from basic and instrumental activities of daily living is limited, particularly in lower-and middle-income (LMIC) countries. Therefore, we examined the issue under the caption, since it is the first step in planning several rehabilitation services.MethodA facility-based cross-sectional study was done to assess the magnitude and predictors of post-stroke limitations in basic activities of daily living (BADL) using the Barthel Index (BI) scale and instrumental activities of daily living (IADL) using the Frenchay Activities Index (FAI) scale among patients who visited Tikur Anbessa Specialized Hospital in Addis Ababa, Ethiopia, Neurology Clinic from April-October, 2022. All patients having a diagnosis of stroke for more than six months duration were enrolled. Descriptive and inferential statistical analyses were done, and measures of estimated crude and adjusted odds ratio with 95% CI were constructed and a p-value less than 0.05 was considered statistically significant. The results are presented in figures and tables.ResultsA total of 150 stroke patients were enrolled in the present study. The mean age of participants was 53 (14.9) years with slight male preponderance (51.3%). Ischemic stroke was present in 106 (70.7%) of them, while 44 (29.3%) had hemorrhagic stroke. Of this, 57 (38%) and 115 (79.3%) of them had limitations in basic and instrumental ADL, respectively. Comorbid cardiac disease (AOR = 6.9; 95%CI = 1.3–37.5) and regular substance use (AOR = 11.1; 95%CI = 1.1–115) were associated with limitations in BADL, while an increase in age (AOR = 1.1; 95%CI = 1.04–1.15) was associated with severe limitations in BADL. Initial stroke severity (AOR = 7.3; 95%CI = 1.2–44.7) was associated with limitations in IADL, whereas depression (AOR = 5.1; 95%CI = 1.1–23.2) was identified as a predictor of severe limitation in IADL.ConclusionLimitation in activities of daily living (ADL) after stroke is common among Ethiopian patients. Therefore, screening for post-stroke limitations in daily activities is essential for further management and rehabilitative plans.

Korean Version of the Longer-Term Unmet Needs After Stroke Questionnaire.

: To translate the 22-item Longer-term Unmet Needs after Stroke (LUNS) questionnaire, validate it in the Korean stroke population, and assess the reliability of face-to-face and telephone surveys. : Sixty-six adult patients with stroke from Seoul National University Bundang Hospital and Kangwon National University Hospital were involved in the validation. Participants were interviewed twice using the LUNS Korean version: first, a face-to-face survey for validation, and second, a telephone survey for test-retest reliability. Participants completed the Frenchay Activities Index (FAI) and Short Form 12 (SF-12) Mental and Physical Component Summary (MCS and PCS) scores at the first interview. For concurrent validity, the differences in health status (FAI, SF-12 MCS and PCS) between the groups that reported unmet needs and those that did not were analyzed for each item. Cohen's kappa and percentage of agreement between the first and second administrations were calculated for each item to determine the test-retest reliability. : The average age of the participants was 61.2±12.8 years and 74.2% were male. Fifty-seven patients were involved in the second interview. Depending on the unmet needs, SF-12 MCS, PCS, and FAI were significantly different in 12 of 22 items. In the test-retest reliability test, 12 items had a kappa of 0.6 or higher, and two had a kappa of <0.4. : The LUNS instrument into Korean (LUNS-K) is a reliable and valid instrument for assessing unmet health needs in patients with stroke. In addition, telephone surveys can be considered reliable.

Factors associated with life-space mobility restriction in home-care older adults receiving home-visit rehabilitation: A cross-sectional multi-center study in Japan.

Life-space mobility (LSM) restriction is a serious issue among older adults using home-visit rehabilitation (HR). This study evaluated physical function, transportation, and other factors not comprehensively tested in previous studies and examined factors associated with the restriction of LSM among older adults using HR. This cross-sectional multi-center study recruited 88 HR users (49 men, 39 women, mean age 79.0 [±7.8] years) living in urban and rural areas from August to October 2020. We administered the Life-Space Assessment (LSA), the Self-Efficacy Scale on Going out among community-dwelling Elderly (SEGE), grip strength, a 30-s chair stand test, Bedside Mobility Scale, Functional Independence Measure, Frenchay Activities Index (FAI), Ikigai-9, and Home and Community Environment (HACE) test. Participants were divided into two groups based on the cut-off value of the LSA scores. In the logistic regression analysis, the dependent variable was LSA scores ≤30, and the independent variables were measured based on objective evaluation items and adjusted for confounding factors (age, sex, and frequency of use of day-care services). Restriction of LSM was significantly associated with FAI (odds ratio [OR] = 0.817, 95% confidence interval [CI] = 0.706-0.945), HACE facilitators (OR = 1.558, 95% CI = 1.168-2.079), and living alone (OR = 12.822, 95% CI = 1.202-136.716). Restriction of LSM is associated with environmental factors, such as assistive devices and household composition, and ability to engage in instrumental activities of daily living. Our findings indicate a great need for focusing on these factors among home-care older adults receiving HR. Geriatr Gerontol Int 2023; ••: ••-••.

Activity level by clinical severity and sex differences in patients with Alzheimer disease and mild cognitive impairment.

To determine how to maintain activity in persons with dementia and mild cognitive impairment, we examined the daily activity level by different degrees of clinical severity and sex differences in patients with Alzheimer's disease and mild cognitive impairment. This study included 92 patients with Alzheimer's disease and 33 patients with mild cognitive impairment who visited our rehabilitation department. The Frenchay Activities Index was used to assess the level of activity. Women had high Frenchay Activities Index scores for household activities, such as meal preparation, washing clothes, and light housework, whereas men had high Frenchay Activities Index scores for social occasions and walking outside. Although activity decreased with the severity of dementia in women, there was no difference in men. Additionally, a negative correlation was observed between the number of people living together and activity in women. To maintain and improve activities in persons with Alzheimer's disease and mild cognitive impairment, it is important to suggest activities that fit the lifestyle of the individual and family caregivers and to provide lifestyle instructions that consider sex differences.

Functionality and quality of life in Brazilian patients 6 months post-stroke.

Surviving a stroke poses a social and economic impact that requires the care system to be reformulated and the patient to be addressed in a comprehensive approach. This study aims to investigate if there is a relationship between functional activities performed before the stroke, patients' clinical and hospitalization data, and functionality and quality of life measures in the first 6 months after the stroke. This study used a prospective cohort of 92 patients. We investigated sociodemographic and clinical data, the modified Rankin Scale (mRS), and the Frenchay Activities Index (FAI) during hospitalization. The Barthel Index (BI) and EuroQol-5D (EQ-5D) were applied at the following time points: 30 days (T1), 90 days (T2), and 180 days (T3) following postictal state. Statistical analysis was conducted using Spearman's coefficient, Friedman's non-parametric test, and multiple linear regression models. No correlation was found between FAI, BI, and EQ-5D average scores. Severe patients, patients with comorbidities, and patients with extended hospital stays showed lower BI and EQ-5D scores □in the follow-up. BI and EQ-5D scores increased. This research found no relationship between activities performed before the stroke and functionalities and quality of life after the stroke, but comorbidities and extended hospital stay were associated with worse outcomes.

The concurrent validity of the Stroke Self-Efficacy Questionnaire Brazil (SSEQ-B) in brazilian stroke survivors

The Stroke Self-Efficacy Questionnaire Brazil (SSEQ-B) is designed to assess the self-efficacy of functional performance after stroke. Objective: To evaluate the concurrent validity of the SSEQ-B in Brazilian stroke survivors in relation to gold-standard measures of instrumental and basic daily living activities as well as quality of life after stroke. Methods: The concurrent validity of the SSEQ-B was tested using the Frenchay Activity Index (FAI), Barthel Index (BI) and Stroke Specific Quality of Life Scale (SS-QOL). Descriptive statistics, the Spearman’s coefficient index, Intraclass correlation coefficient (ICC), Cronbach alpha and achieved post-hoc power (1-ß) analyses were conducted. Results: Seventy-five stroke survivors aged 66.64 ± 12.97 years were included in this study. Total scores from the SSEQ-B were strongly correlated with the FAI (ICC= 0.8 / r= 0.72 / 1-ß= 1.0) and BI (ICC= 0.68 / r= 0.68 / 1-ß= 0.99), but weakly correlated with SS-QOL (ICC= 0.46 / r= 0.65 / 1-ß= 0.94), which suggests stroke self-efficacy is more closely associated with instrumental and daily living activities than the quality of life. Conclusion: The SSEQ-B exhibits good concurrent validity with instrumental and daily living activities and could be useful when assessing stroke self-efficacy in Brazilians.

Factors influencing loneliness among older people using homecare services during the COVID-19 pandemic.

Elderly homecare service users may reduce their level of social participation and interpersonal interactions due to physiological loss, which may lead to loneliness and depression over the years. However, there is a lack of research on loneliness among older people who use homecare services. The purpose of this study was to examine the factors influencing loneliness among older people using homecare services. This is a longitudinal study conducted in communities in Central Taiwan, and data were collected using a structured questionnaire. The questionnaire was first administered as a pre-test to obtain baseline information about the participants, and the same questionnaire was administered as a post-test after 6 months to follow-up. The pre- and post-test questionnaires included five sections, that is, participant demographics, Brief Symptom Rating Scale, Interpersonal Interaction Scale (IIS), Frenchay Activities Index, and UCLA Loneliness Scale (UCLA). A total of 178 participants were recruited in this study. Results indicated that gender, whether participants eat alone or with others at dinner, social media use, perceived economic status, and IIS score were significantly correlated with the loneliness score on the UCLA. Furthermore, there was a significant increase in the loneliness score among male participants in the low loneliness group from baseline to 6 months follow-up. Gender, presence of others at dinner, social media use, perceived economic status, and interpersonal interaction skills are significant factors that influence loneliness among older people using homecare services. Men tend to experience higher levels of loneliness over time.

Identity, social engagement and community participation impact physical activity levels of stroke survivors: A mixed-methods study

Objective To explore how personal characteristics and social engagement impact the physical activity levels of chronic stroke survivors. Design A mixed-methods study comprising in-depth semi-structured interviews and objective 24-h physical activity monitoring. Interviews were thematically analysed, and activity diaries were compared to activity monitor data to attain a complete picture of physical activity. Triangulation explored the relationship between perceptions, beliefs, activity levels and social engagement. Setting Community. Participants Community-dwelling, independently mobile, adult stroke survivors (n = 19). The mean age was 74 (11 SD) years, 52% female, mean time post-stroke 41 (SD 61) months. Main measures Qualitative and quantitative measures including individual semi-structured interviews, accelerometry, activity diaries, self-efficacy, Frenchay Activities Index and Barthel Index. Results Individual identity had the greatest perceived influence on post-stroke physical activity. Pre-stroke identity, meaningful activities and family culture contributed to identity; while social and community activities, self-efficacy, co-morbidities, stroke symptoms and exercise, also impacted physical activity. Participants averaged 5365 (IQR 3378–7854) steps per day and reported a mean self-efficacy for exercise score of 51 (SD 20). Triangulation showed convergent relationships between post-stroke physical activity levels and participant motivation, comorbidities, level of social and community participation, self-efficacy and pre-stroke activity levels. Conclusion Personal identity, social engagement and community participation are important factors to consider when implementing a person-centred approach to increasing physical activity participation post-stroke.

Self-Reported Frailty Screening Tools: Comparing Construct Validity of the Frailty Phenotype Questionnaire and FRAIL.

We examined the construct validity of 2 self-reported frailty questionnaires, the Frailty Phenotype Questionnaire (FPQ) and FRAIL, against the Cardiovascular Health Study frailty phenotype (CHS-FP). Cross-sectional data analysis of longitudinal prospective cohort study. We included data from 230 older adults (mean age: 67.2 ± 7.4years) from the "Longitudinal Assessment of Biomarkers for characterization of early Sarcopenia and Osteosarcopenic Obesity in predicting frailty and functional decline in community-dwelling Asian older adults Study" (GeriLABS 2) recruited between December 2017 and March2019. We compared area under receiver operating characteristic curves (AUC), agreement, correlation, and predictive validity against outcome measures [Short Physical Performance Battery, 5 times repeat chair stand (RCS-5), Frenchay activities index, International Physical Activity Questionnaire, life-space assessment, Social Functioning Scale 8 (SFS-8), EuroQol-5 dimensions (utility value)] using logistic regression adjusted for age, gender, and vascular risk factors. We examined concurrent validity across robust versus prefrail/frail for inflammatory blood biomarkers [tumor necrosis factor receptor 1 and C-reactive protein (CRP)] and dual-energy x-ray absorptiometry body composition [bone mineral density (BMD); appendicular lean mass index (ALMI), and fat mass index (FMI)]. Prevalence of prefrail/frail was 25.7%, 14.8%, and 48.3% for FPQ, FRAIL, and CHS-FP, respectively. Compared with FRAIL, FPQ had better diagnostic performance (AUC= 0.617 vs 0.531, P= .002; sensitivity= 37.8% vs 18.0%; specificity= 85.6% vs 88.2%) and agreement (AC1-Stat= 0.303 vs 0.197). FPQ showed good predictive validity [RCS-5: odds ratio (OR) 2.38; 95% CI: 1.17-4.86; International Physical Activity Questionnaire: OR 3.62; 95% CI:1.78-7.34; SFS-8: OR 2.11; 95% CI: 1.64-5.89 vs FRAIL: all P&gt;.05]. Only FRAIL showed concurrent validity for CRP, compared with both FPQ and FRAIL for TNF-R1. FRAIL showed better concurrent validity for BMD, FMI, and possibly ALMI, unlike FPQ (all P &gt; .05). Our results support complementary validity of FPQ and FRAIL in independent community-dwelling older adults. FPQ has increased case detection sensitivity with good predictive validity, whereas FRAIL demonstrates concurrent validity for inflammation and body composition. With better diagnostic performance and validity for blood biomarkers and clinical outcomes, FPQ has utility for early frailty detection in the community setting.

Sex differences in frequency of instrumental activities of daily living after cardiac rehabilitation and its impact on long-term mortality in patients with heart failure

Abstract Introduction While the major outcome of cardiac rehabilitation for heart failure (HF) is the improvement of exercise tolerance, prognosis, and quality of life, instrumental activities of daily living (IADL) has also been focused on as one of the its outcomes. IADL has been reported to be associated with all-cause mortality and quality of life in community-dwelling people and in patients with stable heart disease, but no report has examined the relationship between IADL after cardiac rehabilitation for HF and prognosis. In addition, it is assumed that sex differences may affect the frequency of performing each component of IADL, but there are no reports examining the association with prognosis by sex. Purpose The present study aimed to investigate the sex differences in frequency of IADL and its impact on outcomes. Methods We retrospectively studied 490 consecutive patients who were admitted due to acute decompensated HF and participated in outpatient cardiac rehabilitation after discharge. The study was performed in accordance with the tenets of the Declaration of Helsinki, and the protocol was approved by the Ethics Committee of our institution. IADL frequency was assessed using the questionnaire-based Frenchay Activities Index (FAI). The primary endpoint was all-cause death and secondary endpoint was combined events (all-cause death and/or readmission due to HF). We performed the Kaplan–Meier and log-rank tests and multivariable Cox regression analysis to evaluate the prognostic predictive capability of the FAI. Results The study population had a median age of 69 (interquartile range [IQR]: 58–76) years, and 33.9% of patients were females. The median FAI score was 24 (IQR: 16–29) points. According to the Youden index based on the area under the curve calculated by the receiver operating characteristics curve, the cut-off values of FAI for all-cause death in all-over, females, and males were 23, 22, and 23 points, respectively. Over a median follow-up period of 4.8 years (IQR: 2.3–6.6 years), all-cause death and combined events were occurred in 95 (19.4%) and 213 (43.5%), respectively. After adjustment for several pre-existing prognostic factors, IADL assessed by the FAI was independently associated with all-cause mortality (hazard ratio [HR]: 0.961, 95% confidence interval [CI]:0.937–0.986) and combined events (HR: 0.968, 95% CI: 0.952–0.985), respectively. In addition, there was no interaction between sex in prognostic capability (P=0.664). Conclusion Lower IADL frequency assessed by FAI at the end of outpatient cardiac rehabilitation was shown to be associated with poorer prognosis in patients with HF, regardless of sex. The IADL level is generally higher in females than in males but seems to be a useful marker for risk stratification at the end of cardiac rehabilitation in both females and males.

Derivation of a screening tool for predicting the risk of falls in community-dwelling older adults with knee osteoarthritis.

The aim of this study was to derive a screening tool for predicting the risk of falls in community-dwelling older adults with knee osteoarthritis. This prospective cohort study was conducted in four orthopedic clinics. The main outcome measure was falls or nonfalls for 5 months, and the predictors were sex, age, BMI, Kellgren-Lawrence grade, laterality, number of comorbidities, pharmacotherapy, physical therapy period, use of a cane, household, previous history of falls, visual analog scale for pain, one-leg standing test (OLST), five times sit-to-stand test (FTSST), and Frenchay activities index. Ninety outpatients (74 females and 16 males) with a mean (SD) age of 73.1 (9.3) years completed a 5-month follow-up. According to the binomial logistic regression analysis, previous history of falls [odds ratio (OR), 6.85; P = 0.019], OLST (OR, 5.97; P = 0.048), and FTSST (OR, 12.93; P = 0.034) were identified as risk factors for falls, and the clinical prediction rule was derived from these variables. The pretest probability of fallers in this study was 21.1% (19 of 90 participants). When the total screening tool score was three points (the participant scored one point for each item: previous history of falls, yes; OLST, ≤6.84 s; FTSST, ≥8.77 s), the positive likelihood ratio was 16:19, and the posttest probability increased to 81.3%. Therefore, this simple screening tool possesses potential clinical utility for identifying patients with knee osteoarthritis at high risk of falls in the future because it demonstrated sufficient diagnostic test accuracy.

Sex Differences in Frequency of Instrumental Activities of Daily Living after Cardiac Rehabilitation and Its Impact on Outcomes in Patients with Heart Failure.

Although instrumental activities of daily living (IADL) are included in the outcomes of cardiac rehabilitation (CR), the relationship between IADL frequency at the end of CR and outcomes between the sexes remains unclear. We aimed to investigate the differences in frequency of IADL between the sexes and its impact on the outcomes. We retrospectively investigated 490 consecutive patients who were admitted for heart failure (HF) and participated in CR post-discharge. IADL frequency was assessed using the questionnaire-based Frenchay Activities Index (FAI). The primary endpoint was all-cause death, and the secondary endpoint was a composite of all-cause death and readmission due to HF. The cut-off values of the FAI for all-cause death in the overall cohort, females, and males were 23, 22, and 23 points, respectively. After adjusting for several factors, IADL assessed using the FAI was independently associated with all-cause mortality (hazard ratio [HR]: 0.961, 95% confidence interval [CI]: 0.937–0.986) and combined events (HR: 0.968, 95% CI: 0.952–0.985), respectively. Additionally, there was no interaction between sex and all-cause mortality. In conclusion, higher IADL frequency after CR was associated with favourable outcomes in patients with HF.
