Abstract P249: Association Between Loneliness and Functionality in an Elderly Population

Background: Functionality plays a pivotal role in the well-being and autonomy of older individuals. Discovering new predictors of functional decline is a pressing concern, with loneliness emerging as an unconventional risk factor for chronic diseases. However, its role in functional limitations remains poorly understood. Hypothesis: Loneliness is an independent predictor of limitations in Activities of Daily Living (ADLs) and Instrumental ADLs (IADLs) among individuals aged 80 or older. Methods: A cross-sectional analysis was conducted using data from Wave 8 of the Survey of Health, Ageing, and Retirement in Europe (SHARE), spanning 28 European countries, for participants aged 80 and above, excluding residents in long-term care institutions. Loneliness was assessed using a reduced version of the R-UCLA Loneliness Scale, including measures of companionship, feeling left out, and isolation on a 3-point Likert scale ("often," "some of the time," "hardly ever or never"). Participants scoring 4 to 9 were categorized as lonely. The outcome was defined as the presence of limitations in one or more of the six ADLs and/or the nine IADLs. Logistic regression models were employed to control for potential confounding factors. Multivariate analysis included covariates with p<0.200 and no multicollinearity. Model quality was evaluated using the area under the ROC curve, and the significance level was set at 5%. The analysis was conducted using IBM SPSS, version 28.0. Results: The study included 7,434 individuals, with 58.2% (n=4,323) being female and a mean age of 84.4 (±3.8) for both genders. A majority of participants (52.5%, n=3,879) had low levels of education (ISCED-97 from 0 to 2). Comorbidities included cardiovascular disease (22%, n=1,634), stroke (7%, n=523), diabetes mellitus (17.2%, n=1,281), cancer (6.6%, n=494), and obesity (16.8%, n=1,180). In the univariate analysis, older adults classified as lonely exhibited an odds ratio (OR) of 2.213 (95% CI: 2.016 - 2.428) for presenting limitations in one or more ADLs/IADLs. The multiple model showed an OR of 1.472 (95% CI: 1.313 - 1.649) for having one or more ADLs/IADLs limitations in the presence of loneliness. This association remained significant even after adjusting for confounders (age, gender, education, chronic diseases, hip fracture, pain and European region). The AUC was 76,4%. Conclusions: Our study reveals an independent link between loneliness and limitations in ADLs and IADLs among individuals aged 80 or older from the SHARE dataset. These findings lend support to interventions aimed at preventing loneliness and preserving functionality in this age group.

Slowness as a Predictor of Functional Decline in Older Adults: Comparison of Moberg Picking-Up Test and Walking Speed.

Slowness, generally assessed by walking speed (WS), is an estimator of frailty and its outcomes. Because of potential difficulties in assessing WS, the Moberg picking-up test (MPUT) might be an alternative. This study investigated the capacity of slowness measurements (WS and MPUT) to predict nonfatal adverse consequences of frailty: primarily, decline in basic activities of daily living (BADL); and secondarily, decline in instrumental activities of daily living (IADL), fall, hospitalization, and incident disease. Observational (prospective longitudinal study). This study used data from the population-based Lausanne cohort 65+. At baseline, 1887 individuals (aged 72-77years) completed both WS (time to walk 20m at usual pace) and MPUT (time to pick up 12 objects) assessments. All outcomes, assessed at 1- and 4-year follow-ups, were entered in separate logistic regression models with adjustment for age, sex, and respective values at baseline. The prediction of all outcomes by either WS or MPUT was assessed using area under the receiver operating characteristic curve and compared by χ2 tests. There were positive associations between slowness either assessed by WS [relative risk (RR)= 2.48; P < .001] or MPUT (RR= 1.91; P < .001) and decline in BADL at 1-year follow-up. These associations remained significant at 4-year follow-up for both WS (RR= 2.28; P < .001) and MPUT (RR= 1.95; P < .001). There was no significant difference between predictive values of slow WS and MPUT for decline in BADL at 1-year (P= .328) and 4-year follow-ups (P= .413). The prediction was not significantly different for secondary outcomes, except for decline in IADL for which the prediction was slightly better for WS. MPUT may be an alternative measurement of slowness with predictive value of functional decline. No significant difference in predictive capabilities of MPUT and WS for specific adverse consequences of frailty is promising in favor of using MPUT for measuring slowness.

Postoperative dysphagia as a predictor of functional decline and prognosis after undergoing cardiovascular surgery.

Post-extubation dysphagia (PED), an often overlooked problem, is a common and serious complication associated with mortality and major morbidity after cardiovascular surgery. Dysphagia is considered an age-related disease, and evaluating its long-term effects is a pressing issue with rapidly progressing ageing worldwide. Therefore, we examined the effect of PED on functional status and long-term cardiovascular events in patients undergoing cardiovascular surgery. This single-centre, retrospective cohort study included 712 patients who underwent elective cardiovascular surgery and met the inclusion criteria. Patients were divided into PED and non-PED groups based on their post-operative swallowing status. The swallowing status was assessed using the Food Intake Level Scale. Functional status was evaluated as hospital-associated disability (HAD), defined as a decrease in activities of daily living after hospital discharge compared with preoperative values. The patients were subsequently followed up to detect major adverse cardiac and cerebrovascular events (MACCEs). Post-extubation dysphagia was present in 23% of the 712 patients and was independently associated with HAD (adjusted odds ratio, 2.70). Over a 3.5-year median follow-up period, MACCE occurred in 14.1% of patients. Multivariate Cox proportional hazard analysis revealed HAD to be independently associated with an increased risk of MACCE (adjusted hazard ratio, 1.85), although PED was not significantly associated with MACCE. Post-extubation dysphagia was an independent HAD predictor, with the odds of HAD occurrence being increased by 2.7-fold due to PED. Hospital-associated disability accompanied by PED is a powerful predictor of poor prognosis. Perioperative evaluation and management of the swallowing status, and appropriate therapeutic interventions, are warranted.

Patterns and Predictors of Functional Decline after Allogeneic Hematopoietic Cell Transplantation in Older Adults

As allogeneic hematopoietic cell transplantation (alloHCT) is increasingly offered to older adults, geriatric assessment (GA) has been identified as a useful tool for predicting outcomes, particularly functional status. However, very few studies have examined the longitudinal change in GA measures in the post-alloHCT period. The objectives of this study were to describe the longitudinal change in GA and quality of life (QoL) measures after alloHCT and to identify predictors of greater functional decline post-transplantation. In this single-center prospective cohort study, patients age ≥50 years scheduled for alloHCT completed a cancer-specific GA and the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT) survey at baseline prior to alloHCT and then at 3, 6, and 12 months post-transplantation. Changes in GA and QoL measures at each post-transplantation time point (3, 6, and 12 months) compared to baseline were analyzed using paired t-tests. Exploration of potential predictors of greater post-transplantation functional decline, as measured by instrumental activities of daily living (IADL) and the Medical Outcomes Study Physical Health scale (MOS-PH), were examined using linear regression and the chi-square 2-sample test of proportions. Mean functional status generally exhibited a pattern of decline at 3 to 6 months post-alloHCT, with recovery to near baseline by 12 months. Mean mental health and emotional QoL were lowest at baseline and improved at all post-transplantation time points. Differences in baseline clinical characteristics were not associated with any differences in functional trajectories. Differences in baseline GA measures-patient-rated Karnofsky Performance Status, IADL, MOS-PH, Timed-Up-and-Go, Blessed Orientation-Memory-Concentration test, and Mental Health Inventory 5-also did not predict greater functional decline at 3 months. Patients whose IADL was improved or maintained at 3 months generally maintained their functional status at 6 and 12 months. Similarly, most patients who had an IADL decline at 3 months still had a functional decline at 6 months, although a proportion did have functional recovery by 12 months. Compared with patients who had improved/maintained IADL at 3 months, those with a decline in IADL at 3 months were significantly more likely to have persistent functional decline at 6 months (P < .0001) and 12 months (P=.02). In older alloHCT recipients, mean functional status declines short term after alloHCT with the possibility of recovery by 6 to 12 months, whereas mean mental and emotional health improve post-alloHCT. Functional decline at 3 months post-alloHCT is associated with persistent functional decline at 12 months.

Higher Veterans Aging Cohort Study 2.0 Index Score Predicts Functional Decline Among Older Adults Living with HIV.

Living with HIV has been proposed as a risk factor for the early development of functional decline. Composite marker tools like the Veterans Aging Cohort Study (VACS) Index, which includes HIV-associated and non-HIV-related markers of disease may better reflect multiorgan system injury and potentially predict functional outcomes. Therefore, the objective of this work is to determine whether higher VACS 2.0 Index scores predicts functional decline among older adults living with HIV (OALWH). Longitudinal study, including 131 adults ages 50 or older who underwent a comprehensive geriatric assessment at baseline and follow-up, at least a year apart. Functional status was determined by the gait speed (seconds for a 4-m distance). Linear regression models were constructed to determine the relationship between VACS 2.0 Index at baseline with gait speed at follow-up adjusted for potential confounders. The median for age was 58.0 years (range 50-84), and 81.7% were male. At baseline, the median VACS 2.0 Index score was 50.4 (interquartile range 42.2-65.3). The adjusted linear regression analysis found that higher baseline VACS 2.0 Index scores were significantly associated with a decline in gait speed (p = .033) at follow-up. The results suggest that the VACS 2.0 Index works as a predictor of functional decline as showed by decline in gait speed and might serve as an easy tool to identify OALWH who might need additional resources or interventions to prevent it.

The Role of Frailty in Predicting 3 and 6 Months Functional Decline in Hospitalized Older Adults: Findings from a Secondary Analysis.

Frailty represents one of the most relevant geriatric syndromes in the 21st century and is a predictor of adverse outcomes in hospitalized older adult, such as, functional decline (FD). This study aimed to examine if frailty, evaluated with the Frailty Index (FI), can predict FD during and after hospitalization (3 and 6 months). Secondary data analysis of a prospective cohort study of 101 hospitalized older adults was performed. The primary outcome was FD at discharge, 3 and 6 months. The FI was created from an original database using 40 health deficits. Functional decline models for each time-point were examined using a binary logistic regression. The prevalence of frailty was 57.4% with an average score of 0.25 (±0.11). Frail patients had significant and higher values for functional decline and social support for all time periods and more hospital readmission in the 3 month period. Multivariable regression analysis showed that FI was a predictor of functional decline at discharge (OR = 1.07, 95% CI = 1.02–1.14) and 3-month (OR = 1.05, 95% CI = 1.01–1.09) but not 6-month (OR = 1.03, 95% CI = 0.99–1.09) follow-up. Findings suggest that frailty at admission of hospitalized older adults can predict functional decline at discharge and 3 months post-discharge.

Predictors of Functional Decline in Activities of Daily Living at Discharge in Patients After Cardiovascular Surgery.

This study aimed to investigate the trajectory of functional recovery of activities of daily living (ADL) from the time of admission up to hospital discharge, and explored which preoperative and postoperative variables were independently associated with functional decline in ADL at discharge of patients after cardiovascular surgery. In this observational study, we evaluated ADL preoperatively and at discharge using the Functional Independence Measure (FIM) in patients after cardiovascular surgery. Functional decline in ADL was defined as scoring 1-5 on any one of the FIM items at discharge. Multiple logistic regression was performed to predict the functional decline in ADL at discharge. We found that 18.8% of elective cardiovascular surgery patients suffered from decreased ADL at discharge. The Mini-Mental State Examination (odds ratio (OR): 0.573, 95% confidence interval (CI): 0.420-0.783), gait speed (OR: 0.032, 95% CI: 0.003-0.304) and initiation of walking around the bed (OR: 1.277, 95% CI: 1.103-1.480) were independently associated with decreased ADL at discharge. A functional decline in ADL at discharge can be predicted using preoperative measures of cognitive function, preoperative gait speed and postoperative day of initiation of walking. These results show that preoperative cognitive screening and gait speed assessments can be used to identify patients who might require careful postoperative planning, and for whom early postoperative rehabilitation is needed to prevent serious functional ADL deficits.

Hospitalized older adult: predictors of functional decline.

Objective:to identify the predictors of functional decline in hospitalized individuals aged 70 or over, between: baseline and discharge; discharge and follow-up, and baseline and three-month follow-up.Method:a prospective cohort study conducted in internal medicine services. A questionnaire was applied (clinical and demographic variables, and predictors of functional decline) at three moments. The predictors were determined using the binary logistic regression model.Results:the sample included 101 patients, 53.3% female, mean age of 82.47 ± 6.57 years old. The predictors that most contributed to decline in hospitalization were the following: previous hospitalization (OR=1.8), access to social support (OR=4.86), cognitive deficit (OR=6.35), mechanical restraint (OR=7.82), and not having a partner (OR=4.34). Age (OR=1.18) and medical diagnosis (OR=0.10) were the predictors between discharge and follow-up. Being older, delirium during hospitalization (OR=5.92), and presenting risk of functional decline (OR=5.53) were predictors of decline between the baseline and follow-up.Conclusion:the most relevant predictors were age, previous hospitalization, cognitive deficit, restraint, social support, not having a partner, and delirium. Carrying out interventions aimed at minimizing the impact of these predictors can be an important contribution in the prevention of functional decline.

Predictors for functional decline after an injurious fall: a population-based cohort study

BackgroundThe functional consequences of injurious falls are well known. However, studies of the factors that can modify trajectories of disability after an injury from a fall are scarce.AimsWe aimed to investigate whether sociodemographic and health-related factors may impact this association.MethodsThe study population consisted of 1426 community-dwelling older adults (≥ 60 years) from the SNAC-K cohort study in Stockholm, Sweden. Functional status over 12 years of follow-up was assessed using the number of limitations in basic and instrumental activities of daily living. Sex, cohabitation status, physical activity, and self-rated health were assessed at baseline. Injurious falls were defined as falls requiring healthcare and were assessed over 3 years starting at baseline. Data were analyzed using linear-mixed effects models.ResultsThe fastest increase in the number of disabilities was observed in those who had endured an injurious fall and were living alone (β coefficient = 0.408; p < 0.001), been physically inactive (β coefficient = 0.587; p < 0.001), and had poor self-rated health (β coefficient = 0.514; p < 0.001). The negative impact of these factors was more pronounced among fallers compared to non-fallers.DiscussionLiving alone, being physically inactive, and having poor self-rated health magnifies the negative effect of an injurious fall on functional status. Among individuals who endure an injurious fall, the heterogeneity in long-term functional status is substantial, depending on the individuals’ characteristics and behaviors.ConclusionsThese findings emphasize the need for a person-centered approach in care provision and can guide secondary prevention within health care.

Assessment of hand-grip and key-pinch strength at three arm positions among healthy college students: Dominant versus non-dominant hand.

ObjectiveGrip strength is important for independent self-care and is a predictor of functional decline. This study aimed to determine if healthy individuals would demonstrate different hand-grip and key-pinch strengths at three different arm positions and in comparisons between dominant and non-dominant hands.MethodsA total of 61 right-hand–dominant male college students aged 19–23 years were consecutively recruited from the College of Medical Rehabilitation Sciences. Three researchers performed the measurements. All tests were performed with the JAMAR® hand-grip dynamometer handle set in its second position. Participants were instructed to squeeze the handle of the hand-grip dynamometer in the 90° elbow flexion, 90° shoulder flexion, and arm dangled positions. For assessment of key-pinch strength, every participant had to squeeze the thumb pad against the lateral aspect of the middle phalanx of the index finger. Key-pinch strength was measured in the same positions used for assessment of hand-grip strength. Participants were blinded for the outcome measurements. The significance level was set at p < 0.05.ResultsThe hand-grip and key-pinch strengths did not show significant effects. Comparison of right and left hand-grip strengths also showed insignificant differences. However, the key-pinch strength showed a significant increase in favour of the dominant hand.ConclusionsClinicians can choose any upper-extremity position to measure hand-grip and key-pinch strength. Furthermore, clinicians should aim to maintain and restore almost equal scores for hand-grip and pinch strength of the dominant and non-dominant hands to ensure better hand function.

GAIT SPEED AND CHILDHOOD-TO-MIDLIFE BRAIN HEALTH: RETHINKING GAIT

Background: Gait speed is a well-known predictor of functional decline and mortality in older adults, but little is known about the origins of gait speed earlier in life. We tested the hypothesis that slow gait reflects accelerated biological aging already at midlife, as well as poor neurocognitive functioning in childhood and childhood-to-midlife cognitive decline. Methods: Prospective study of the population-representative Dunedin Study birth cohort (n=1,037), followed to age 45 (until April 2019). We measured age-45 gait speed in 904 (90.7%) participants and tested associations with key life course factors. Results: The mean (SD) gait speeds (m/s) were: usual: 1.30 (0.17); dual task: 1.16 (0.23); and maximum: 1.99 (0.29). Among midlife adults, those with more physical limitations (β -0.27; P<.001), poorer physical functions (β 0.24–0.36; all P<.001), accelerated biological aging across multiple organ systems (β -0.33), older facial appearance (β -0.25), smaller brain volume (β 0.15), more cortical thinning (β 0.09), smaller cortical surface area (β 0.13), and more white matter hyperintensities (β -0.09) had slower gait speed, all P<.05. Participants with lower IQ in childhood (β 0.34) and midlife (β 0.38) and who exhibited childhood-to-midlife cognitive decline (β 0.10) had slower gait speed at midlife, all P<.01. Adults with poorer neurocognitive function as early as age 3 had slower gait in midlife (β 0.26; P<.001). Conclusion: Adults’ gait speed is more than an indicator of geriatric functional status, it is also an index of midlife aging and lifelong brain health.

Sarcopenia Indicators as Predictors of Functional Decline and Need for Care among Older People.

Sarcopenia is associated with poor health outcomes. We examined the relative roles of muscle mass, strength, physical performance and obesity as health predictors among older sarcopenic people. This prospective study examined community-dwelling people aged 75+ (N=262). Porvoo Sarcopenia and Nutrition Trial. We collected demographic data and medical history by postal questionnaire including RAND-36 at baseline and at four years and measured BMI, Short Physical Performace Battery (SPPB), hand-grip strength, cognition and two surrogate measures of muscle mass; the Single Frequency Skeletal Muscle Index (SF-SMI) and the Calf Intracellular Resistance Skeletal Muscle Index (CRi-SMI). Adjusted for age and gender, independent outdoors mobility was predicted positively by baseline physical functioning scores in RAND-36 (p<0.001), the SPPB (p<0.001), the two-minute step test (p<0.001), and grip strength (p=0.023), as well as CRi-SMI (p<0.001). However, the prediction was negative in BMI (p<0.001) and the Charlson co-morbidity Index (p= 0.004). Similar associations were found when the physical component RAND-36 was used as an outcome measure. The use of home care was predicted by high co-morbidity (p=0.057) and low scores in RAND-36 (p<0.001), SPPB (p<0.001) and the two-minute step test (p<0.001), and low CRi-SMI (p<0.001). CRi-SF was a more consistent predictor than SF-SMI, which was partly masked by BMI. Controlled for age, gender and comorbidity, a 10% difference in CRi-SMI was associated with a 4% higher probability (p=0.019) of independently living at home, whereas the respective figures for SF-SMI and BMI were -18% (p=0.098) and -14% (p=0.088). In contrast to SF-SMI, high CRi-SMI appeared to indicate good prognosis and less need of care, independently of BMI.

Geriatric Assessment and Functional Decline in Older Patients with Lung Cancer.

Older patients with lung cancer are a heterogeneous population making treatment decisions complex. This study aims to evaluate the value of geriatric assessment (GA) as well as the evolution of functional status (FS) in older patients with lung cancer, and to identify predictors associated with functional decline and overall survival (OS). At baseline, GA was performed in patients ≥70years with newly diagnosed lung cancer. FS measured by activities of daily living (ADL) and instrumental activities of daily living (IADL) was reassessed at follow-up to define functional decline and OS was collected. Predictors for functional decline and OS were determined. Two hundred and forty-five patients were included in this study. At baseline, GA deficiencies were present in all domains and ADL and IADL were impaired in 51 and 63% of patients, respectively. At follow-up, functional decline in ADL was observed in 23% and in IADL in 45% of patients. In multivariable analysis, radiotherapy was predictive for ADL decline. No other predictors for ADL or IADL decline were identified. Stage and baseline performance status were predictive for OS. Older patients with lung cancer present with multiple deficiencies covering all geriatric domains. During treatment, functional decline is observed in almost half of the patients. None of the specific domains of the GA were predictive for functional decline or survival, probably because of the high impact of the aggressiveness of this tumor type leading to a poor prognosis.

Factores predictores de pérdida funcional al alta en ancianos hospitalizados por enfermedad aguda

ObjectiveTo compare baseline characteristics and those found during hospitalisation as predictors of functional decline at discharge (FDd) in elderly patients hospitalised due to acute illness. Material and methodA review was made of the computerized records of patients admitted to a Geriatric Acute Unit of a tertiary hospital over a 10 year period. A record was made of demographic, clinical, functional and health-care variables. Functional decline at discharge (FDd) was defined by the difference between the previous Barthel Index (pBI) and the discharge Barthel Index (dBI). The percentage of FDd (%FDd=(pBI−dBI/pBI)×100) was calculated. The variables associated with greater %FDd in the bivariate analysis were included in multivariate logistic regression models. The predictive capacity of each model was assessed using the area under the ROC curve. ResultsThe factors associated with greater %FDd were advanced age, female gender, to live in a nursing home, cognitive impairment, better baseline functional status and worse functional status at admission, number of diagnoses, and prolonged stay. The area under the ROC curve for the predictive models of %FDd was 0.638 (95% CI: 0.615-0.662) based on the previous situation, 0.756 (95% CI: 0.736-0.776) based on the situation during admission, and 0.952 (95% CI: 0.944-0.959) based on a combination of these factors. ConclusionsThe overall assessment of patient characteristics, both during admission and baseline, may have greater value in prediction of FDd than analysis of factors separately in elderly patients hospitalised due to acute illness.

Symptoms of Apathy Independently Predict Incident Frailty and Disability in Community-Dwelling Older Adults.

Although depressive symptoms are widely recognized as a predictor of functional decline among older adults, little is known about the predictive utility of apathy in this population. We prospectively examined apathy symptoms as predictors of incident slow gait, frailty, and disability among non-demented, community-dwelling older adults. We examined 2 independent prospective cohort studies-the LonGenity study (N = 625, 53% women, mean age = 75.2 years) and the Central Control of Mobility in Aging (CCMA) study (N = 312, 57% women, mean age = 76.4 years). Individuals were recruited from 2008 to 2014. Apathy was assessed using 3 items from the Geriatric Depression Scale. Slow gait was defined as 1 standard deviation or more below age- and sex-adjusted mean values, frailty was defined using the Cardiovascular Health Study criteria, and disability was assessed with a well-validated disability scale. The prevalence of apathy was 20% in the LonGenity cohort and 26% in the CCMA cohort. The presence of apathy at baseline, independent of depressive symptoms (besides apathy), increased the risk of developing incident slow gait (hazard ratio [HR] = 2.10; 95% CI, 1.36-3.24; P = .001), frailty (HR = 2.86; 95% CI, 1.96-4.16; P < .001), and disability (HR = 3.43; 95% CI, 1.73-6.79; P < .001) in the pooled sample. These associations remained significant when accounting for demographics, medical illnesses, and cognitive function. Apathy is associated with increased risk of developing slow gait, frailty, and disability, independent of other established risk factors, in non-demented older adults. Apathy should be screened for as a potentially preventable cause of functional decline in clinical psychiatric settings.

Functional trajectories before and after a new cancer diagnosis among community-living older adults.

e21547 Background: We characterized distinct functional trajectories among older adults in the year before and after a new cancer diagnosis and identified factors associated with functional decline. Methods: Among a cohort study of persons 70+ y, we identified 170 participants (lung (15.7%), breast (12.4%), prostate (7.8%); 31.8% incurable at diagnosis)) with an incident cancer diagnosis from 1998-2014. We followed their functional course using 13 basic, instrumental, and mobility activities measured during monthly interviews. To identify functional trajectories, we fit a group-based trajectory model of the 13-item disability scale 12-months before and 12-months after the cancer diagnosis. Regression modeling determined predictors of functional decline, defined as a higher count on the 13-item disability scale. Results: Three pre-cancer functional trajectories were identified (mean age at diagnosis: 83 y (73-105 y); similarly, 3 post-cancer functional trajectories were identified among the 158 non-decedents. Participants with severe disability pre-diagnosis remained severely disabled post-diagnosis. Approximately 40% of participants with mild or moderate disability pre-diagnosis transitioned to a worse functional trajectory post-diagnosis (see Table). Moderate and severe disability pre-diagnosis were significantly associated with functional decline post-diagnosis (moderate vs. mild aRR: 3.10; 95% CI: 2.24-4.30; severe vs. mild aRR: 5.71; 95% CI: 3.60-9.07). Depressive symptoms (RR, 1.40; 95% CI: 1.02-1.91), and incurable stage (RR, 2.16; 95% CI: 1.54-3.03) were also associated with functional decline. Conclusions: Approximately 40% of older adults experienced functional decline after a new cancer diagnosis. Pre-cancer diagnosis functional trajectory, depressive symptoms, and incurable stage were significant predictors of post-diagnosis functional decline. [Table: see text]

Can Non-invasive Ventilation Settings Predicts Functional and Survival Outcome in ALS Patients?

Introduction: The lack of more specific tools, with low costs, that may be associated with the ALSFRS-R (Amyotrophic Lateral Sclerosis Functional Scale-Revised) score to assist in analyzing the prognosis, is a constraint factor in the follow-up of ALS ventilated patients. Objective: we analyzed the potential predictors of ALSFRS-R functional decline related to Non-Invasive ventilation (NIV) settings, Nocturnal Pulse Oximetry (NPO), and Pulmonary Function Test (PFT). Methods: Prospective, comparative trial of 60 consecutive ALS patients, compliant to NIV, during 5 years of follow-up. Subjects were assigned to Group 1 (not-survivors) or Group 2 (survivors) at end of study. Data from ALSFRS-R, NPO, PFT and NIV settings were collected once each three months. Results: No clinical or laboratory differences were observed between groups for any variable at admission. Disease duration from onset as well as Total use of NIV presented non-significant differences at end of study. However, these 2 variables were correlated positively with Expiratory Positive Airways Pressure (EPAP), Inspiratory Positive Airways Pressure (IPAP) and backup breath rate (all parameters of NIV), maximal inspiratory pressure (MIP-PFT), and SpO2mean (NPO). Multivariate Cox regression analysis showed that data from NIV settings and PFT were predictors of functional decline. Conclusions: For the first time, determinants of functional decline are significantly related to NIV equipment settings as well as to compliance data.

Self-reported health status as a predictor of functional decline in a community-dwelling elderly population: Nationwide longitudinal survey in Korea.

As the elderly population is increasing, the prediction and prevention of functional decline in older adults are of great concern. The present study aimed to evaluate whether poor self-reported health status (SRHS) could predict functional decline after 2 years in the elderly population. Data from the Korean Longitudinal Study of Aging panel, a national representative sample of aging Koreans, were used. Participants of the investigation were the elderly population aged 65 years or more without disability in carrying out activities of daily living (ADL) at baseline. The survey asked respondents about their subjective health status. Setting the respondents who stated their health status as "very good" or "good" as the reference group, multivariable logistic regression analysis was carried out to compare functional decline according to the baseline SRHS. A total of 2824 participants were included in the analysis. Among them, 138 (4.9 %) reported functional decline of at least one of the seven ADL components after 2 years. In multivariable logistic regression analysis, SRHS was significantly associated with subsequent functional decline in respondents who chose "Bad" (odds ratio 3.32, 95% confidence interval 1.71-6.44) or "Very bad" (OR 4.75, 95% CI 2.12-10.66). Furthermore, poorer SRHS was significantly associated with subsequent impairment in each ADL component. Also, SRHS predicted overall subsequent impairment in the instrumental ADL. SRHS predicted functional decline after 2 years in older adults without baseline disabilities. SRHS can be a good predictor of future functional decline in the elderly population.

Rising Energetic Cost of Walking Predicts Gait Speed Decline With Aging.

Slow gait is a robust biomarker of health and a predictor of functional decline and death in older adults, yet factors contributing to the decline in gait speed with aging are not well understood. Previous research suggests that the energetic cost of walking at preferred speed is inversely associated with gait speed, but whether individuals with a rising energetic cost of walking experience a steeper rate of gait speed decline has not been investigated. In participants of the Baltimore Longitudinal Study of Aging, the energetic cost of overground walking at preferred speed (mL/kg/m) was assessed between 2007 and 2014 using a portable indirect calorimeter. The longitudinal association between the energetic cost of walking and usual gait speed over 6 meters (m/s) was assessed with multivariate linear regression models, and the risk of slow gait (<1.0 m/s) was analyzed using Cox proportional hazards models. The study population consisted of 457 participants aged 40 and older who contributed 1,121 person-visits to the analysis. In fully adjusted models, increases in the energetic cost of walking predicted the rate of gait speed decline in those older than 65 years (β = -0.008 m/s, p < .001). Moreover, those with a higher energetic cost of walking (>0.17mL/kg/m) had a 57% greater risk of developing slow gait compared with a normal energetic cost of walking (≤0.17mL/kg/m; adjusted hazard ratio = 1.57, 95% confidence interval: 1.01-2.46). These findings suggest that strategies to maintain walking efficiency hold significant implications for maintaining mobility in late life. Efforts to curb threats to walking efficiency should focus on therapies to treat gait and balance impairments, and reduce clinical disease burden.
