Objectives
Initial gait speed is a good predictor of dementia in later life. This prospective study used repeated measures analysis to identify potential gait performance trajectory patterns and to determine whether gait performance trajectory patterns were associated with incident disabling dementia among community-dwelling older Japanese.Design
A prospective, observational, population-based follow-up study.Setting
Japan, 2002 to 2014.Participants
A total of 1686 adults without dementia (mean [SD] age, 71.2 [5.6] years; women, 56.3%) aged 65 to 90 years participated in annual geriatric health assessments during the period from June 2002 through July 2014. The average number of follow-up assessments was 3.9, and the total number of observations was 6509.Measurements
Gait performance was assessed by measuring gait speed and step length at usual and maximum paces. A review of municipal databases in the Japanese public long-term care insurance system revealed that 196 (11.6%) participants developed disabling dementia through December 2014.Results
We identified 3 distinct trajectory patterns (high, middle, and low) in gait speed and step length at usual and maximum paces in adults aged 65 to 90 years; these trajectory patterns showed parallel declines among men and women. After adjusting for important confounders, participants in the low trajectory groups for gait speed and step length at usual pace were 3.46 (95% confidence interval 1.88–6.40) and 2.12 (1.29–3.49) times as likely to develop incident disabling dementia, respectively, as those in the high trajectory group. The respective values for low trajectories of gait speed and step length at maximum pace were 2.05 (1.02–4.14) and 2.80 (1.48–5.28), respectively.Conclusions
Regardless of baseline level, the 3 major trajectory patterns for gait speed and step length tended to show similar age-related changes in men and women in later life. Individuals with low trajectories for gait speed and step length had a higher dementia risk, which highlights the importance of interventions for improvements in gait performance, even among older adults with low gait performance. 相似文献2.

Objectives
Cognitive frailty, a condition describing the simultaneous presence of physical frailty and mild cognitive impairment, has been recently defined by an international consensus group. We estimated the predictive role of a “reversible” cognitive frailty model on incident dementia, its subtypes, and all-cause mortality in nondemented older individuals. We verified if vascular risk factors or depressive symptoms could modify this predictive role.Design
Longitudinal population-based study with 3.5- and 7-year of median follow-up.Setting
Eight Italian municipalities included in the Italian Longitudinal Study on Aging.Participants
In 2150 older individuals from the Italian Longitudinal Study on Aging, we operationalized reversible cognitive frailty with the presence of physical frailty and pre-mild cognitive impairment subjective cognitive decline, diagnosed with a self-report measure based on item 14 of the Geriatric Depression Scale.Measurements
Incidence of dementia, its subtypes, and all-cause mortality.Results
Over a 3.5-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia [hazard ratio (HR) 2.30, 95% confidence interval (CI) 1.02–5.18], particularly vascular dementia (VaD), and all-cause mortality (HR 1.74, 95% CI 1.07–2.83). Over a 7-year follow-up, participants with reversible cognitive frailty showed an increased risk of overall dementia (HR 2.12, 95% CI 1.12–4.03), particularly VaD, and all-cause mortality (HR 1.39, 95% CI 1.03–2.00). Vascular risk factors and depressive symptoms did not have any effect modifier on the relationship between reversible cognitive frailty and incident dementia and all-cause mortality.Conclusions
A model of reversible cognitive frailty was a short- and long-term predictor of all-cause mortality and overall dementia, particularly VaD. The absence of vascular risk factors and depressive symptoms did not modify the predictive role of reversible cognitive frailty on these outcomes. 相似文献3.

Background
Comorbid depression is highly prevalent in geriatric patients and associated with functional loss, frequent hospital re-admissions, and a higher mortality rate. Cognitive behavioral psychotherapy (CBT) has shown to be effective in older depressive patients living in the community. To date, CBT has not been applied to older patients with acute physical illness and comorbid depression.Objectives
To evaluate the effectiveness of CBT in depressed geriatric patients, hospitalized for acute somatic illness.Design
Randomized controlled trial with waiting list control group.Setting
Postdischarge intervention in a geriatric day clinic; follow-up evaluations at the patients’ homes.Participants
A total of 155 randomized patients, hospitalized for acute somatic illness, aged 82 ± 6 years and suffering from depression [Hospital Anxiety and Depression Scale (HADS) scores >7]. Exclusion criteria were dementia, delirium, and terminal state of medical illness.Intervention
Fifteen, weekly group sessions based on a CBT manual. Commencement of psychotherapy immediately after discharge in the intervention group and a 4-month waiting list interval with usual care in the control group.Measurements
HADS depression total score after 4 months. Secondary endpoints were functional, cognitive, psychosocial and physical status, resource utilization, caregiver burden, and amount of contact with physician.Results
The intervention group improved significantly in depression scores (HADS baseline 18.8; after 4 months 11.4), whereas the control group deteriorated (HADS baseline 18.1; after 4 months 21.6). Significant improvement in the intervention group, but not in the control group, was observed for most secondary outcome parameters such as the Barthel and Karnofsky indexes. Intervention effects were less pronounced in patients with cognitive impairment or acute fractures.Conclusions
CBT is feasible and highly effective in geriatric patients. The benefits extend beyond effective recovery and include improvement in physical and functional parameters. Early diagnosis, good access to psychotherapy, and early intervention could improve care for depressive older patients.5.

Objectives
To investigate the prevalence and factors associated with the use of medications of questionable benefit throughout the final year of life of older adults who died with dementia.Design
Register-based, longitudinal cohort study.Setting
Entire Sweden.Participants
All older adults (≥75 years) who died with dementia between 2007 and 2013 (n = 120,067).Measurements
Exposure to medications of questionable benefit was calculated for each of the last 12 months before death, based on longitudinal data from the Swedish Prescribed Drug Register.Results
The proportion of older adults with dementia who received at least 1 medication of questionable benefit decreased from 38.6% 12 months before death to 34.7% during the final month before death (P < .001 for trend). Among older adults with dementia who used at least 1 medication of questionable benefit 12 months before death, 74.8% remained exposed until their last month of life. Living in an institution was independently associated with a 15% reduction of the likelihood to receive ≥1 medication of questionable benefit during the last month before death (odds ratio 0.85, 95% confidence interval 0.88–0.83). Antidementia drugs accounted for one-fifth of the total number of medications of questionable benefit. Lipid-lowering agents were used by 8.3% of individuals during their final month of life (10.2% of community-dwellers and 6.6% of institutionalized people, P < .001).Conclusion
Clinicians caring for older adults with advanced dementia should be provided with reliable tools to help them reduce the burden of medications of questionable benefit near the end of life. 相似文献6.

Objectives
We aimed to (1) study factors that determine the use of invasive procedures in the management of acute myocardial infarction (AMI) in patients with dementia and (2) determine whether the use of invasive procedures was associated with their better survival.Design
Cohort study based on patients registered in the Swedish Dementia Registry (SveDem), 2007–2012. Median follow-up time was 228 days.Setting
Patients diagnosed with dementia in specialist memory clinics and primary care units in Sweden.Participants
A total of 525 patients with dementia who suffered AMI (mean age 89 years, 54% women).Measurements
Information on AMI and use of invasive procedures (coronary angiography and percutaneous coronary intervention) was obtained from Swedish national health registers. Binary logistic regression was applied to study associations of patients’ characteristics with the use of invasive procedures; odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Survival was analyzed with Kaplan-Meier curves; log-rank test was used to compare survival of patients who received an invasive procedure versus those who did not receive it. Cox regression was applied to study association of the invasive procedures with all-cause mortality; hazard ratios (HRs) with 95% CIs were calculated.Results
One hundred ten patients (21%) with dementia received an invasive procedure in the management of AMI. After multivariate adjustment, lower age and higher global cognitive status were associated with the use of invasive procedures. The invasively managed patients survived longer (P = .001). The use of invasive procedures was associated with a lower risk of all-cause mortality, adjusting for type of AMI and dementia disorder, age, gender, registration unit, history of AMI and comorbidity score (HR 0.35, 95% CI 0.21–0.59), or total number of drugs (HR 0.34, 95% CI 0.20–0.58).Conclusion
Age and cognitive status determine the use of invasive procedures in patients with dementia. This study suggests that the invasive management of AMI has a benefit for survival of patients with dementia. 相似文献7.

Objectives
To study pain prevalence, pain type, and its pharmacological treatment in Dutch nursing home residents in relation to dementia subtype and dementia severity.Design
Data were collected as part of the PAINdemiA study, an observational cross-sectional study conducted between May 2014 and December 2015.Setting
Ten nursing homes in the Netherlands.Participants
A total of 199 nursing home residents in various stages of dementia.Measurements
We collected data on pain (by observation: MOBID-2 Pain Scale and by self-report scales), pain type, pain medication, dementia subtype, dementia severity (GDS), and demographic features.Results
In the whole sample, the prevalence of pain was 43% (95% confidence interval 36%–50%) using the MOBID-2 Pain Scale. Regardless of regularly scheduled analgesics, approximately one-third of the residents with pain suffered from moderate to severe pain. Pain assessment with the MOBID-2 Pain Scale showed no difference in pain between dementia subtypes, but residents with more severe dementia experienced pain more often than those with less severe dementia (27% vs 15%). The prevalence of self-reported pain was significantly higher in residents with vascular dementia (VaD) (54%) compared with those with Alzheimer disease (18%) and other dementia subtypes (14%). Nociceptive pain was the predominant type of pain (72%) followed by mixed pain (25%). Acetaminophen was the most prescribed analgesic (80%).Conclusion
Most of the participating nursing home residents had no pain; however, pain was observed more often in residents with severe dementia, whereas residents in the early stages of VaD self-reported pain more often that those with other dementia subtypes.As one-third of the residents with clinically relevant pain had moderate to severe pain regardless of using pain medication, more focus should be on how pain management could use more tailored approaches and be regularly adjusted to individual needs. 相似文献8.

Background
Although the older population is increasing worldwide, there is a marked deficit in the number of persons trained in geriatrics. It is now recognized that early detection and treatment of geriatric syndromes (frailty, sarcopenia, anorexia of aging, and cognitive decline) will delay or avert the development of disability.Objectives
To identify simple screening programs available for primary health professionals to identify geriatric syndromes.Data sources
PubMed for the last 5 years and study authors.Results
A number of screening programs for early detection of geriatric syndromes have been developed for use by primary care health providers, for example, EasyCare, Gérontopôle Frailty Screening Tool, the Rapid Geriatric Assessment, the Kihon Checklist, and others.Limitations
This is an evolving area with limited information on the outcomes of intervention and possible harms.Conclusion
Validated screening programs exist but more work is required to determine their utility in improving outcomes of older persons. 相似文献9.

Objectives
To evaluate the prevalence of cognitive impairment (CI), including mild CI and dementia, in elderly patients with syncope and unexplained falls. In this population, we compared the use of the Mini-Mental State Examination (MMSE) with a cognitive screening test that assesses executive dysfunction typical of subcortical (vascular) CI, that is, the Montreal Cognitive Assessment (MoCA).Design
Observational cohort study.Setting
Outpatient fall and syncope clinic.Participants
Consecutive patients aged ≥65 years with syncope and unexplained falls without loss of consciousness.Measurements
Baseline characteristics, functional status, MMSE, MoCA, and magnetic resonance imaging scans of the brain. Main outcome: prevalence of CI, comparing the MMSE with the MoCA. CI was defined as an MMSE/MoCA score <26. Secondary outcomes: MMSE/MoCA overall and subdomain scores, Fazekas and medial temporal lobe atrophy scores.Results
We included 200 patients, mean age 79.5 (standard deviation 6.6) years (Syncope Group: n = 101; Fall Group: n = 99). Prevalence of CI was 16.8% (MMSE) versus 60.4% (MoCA) in the Syncope Group (P < .001) and 16.8% (MMSE) versus 56.6% (MoCA) in the Fall Group (P < .001). Prevalence of CI did not differ between the Syncope Group and Fall Group with either method. Executive dysfunction was present in both groups.Conclusion
CI is as common in elderly patients with syncope as it is in patients with unexplained falls, with an overall prevalence of 58%. The MMSE fails as a screening instrument for CI in these patients, because it does not assess executive function. Therefore, we recommend the MoCA for cognitive screening in older patients with syncope and unexplained falls. 相似文献10.

Objectives
To investigate the affective, social, behavioral, and physiological effects of the companion robot Paro for people with dementia in both a day care center and a home setting.Design
A pilot block randomized controlled trial over 12 weeks. Participants were randomized to the intervention (Paro) or control condition (standard care).Setting
Two dementia day care centers and participants’ homes in Auckland, New Zealand.Participants
Thirty dyads (consisting of a care recipient with dementia and their caregiver) took part in this study. All care recipients attended dementia day care centers at Selwyn Foundation and had a formal diagnosis of dementia.Intervention
Thirty-minute unstructured group sessions with Paro at the day care center were run 2 to 3 times a week for 6 weeks. Participants also had Paro at home for 6 weeks.Measurements
At the day care centers, observations of the care recipients’ behavior, affect, and social responses were recorded using a time sampling method. Observations of interactions with Paro for participants in the intervention were also recorded. Blood pressure and salivary cortisol were collected from care recipients before and after sessions at day care. In the home setting, level of cognition, depressive symptoms, neuropsychiatric symptoms, behavioral agitation, and blood pressure were measured at baseline, 6 weeks, and 12 weeks. Hair cortisol measures were collected at baseline and at 6 weeks.Results
Observations showed that Paro significantly improved facial expressions (affect) and communication with staff (social interaction) at the day care centers. Subanalyses showed that care recipients with less cognitive impairment responded significantly better to Paro. There were no significant differences in care recipient dementia symptoms, nor physiological measures between the intervention and control group.Conclusion
Paro shows promise in enhancing affective and social outcomes for certain individuals with dementia in a community context. Larger randomized controlled trials in community settings, with longer time frames, are needed to further specify the contexts and characteristics for which Paro is most beneficial. 相似文献11.

Objectives
A simple and inexpensive tool for screening of sarcopenia would be helpful for clinicians. The present study was performed to determine whether the SARC-F questionnaire is useful in screening of patients with cardiovascular disease (CVD) for impaired physical function.Design
Cross-sectional study.Setting
Single university hospital.Participants
A total of 235 Japanese patients ≥65 years old admitted to our hospital for CVD.Measurements
SARC-F, handgrip strength, leg strength, respiratory muscle strength, standing balance, usual gait speed, Short Physical Performance Battery (SPPB) score, and 6-minute walking distance were measured before discharge from hospital. The patients were divided into 2 groups according to SARC-F score: SARC-F < 4 (nonsarcopenia group) and SARC-F ≥ 4 (sarcopenia group).Results
The sarcopenia prevalence rate was 25.5% and increased with age (P trend < .001). The sarcopenia group (SARC-F score ≥ 4) had significantly lower handgrip strength, leg strength, and respiratory muscle strength, poorer standing balance, slower usual gait speed, lower SPPB score, and shorter 6-minute walking distance compared to the nonsarcopenia group (SARC-F score < 4). Patients in the sarcopenia group had consistently poorer physical function even after adjusting for covariates.Conclusion
The SARC-F questionnaire is a useful screening tool for impaired physical function in elderly CVD patients. These findings support the use of the SARC-F for screening in hospital settings. 相似文献12.

Objectives
The distinction between dementia and mild cognitive impairment (MCI) relies upon the evaluation of independence in instrumental activities of daily living (IADL). Self- and informant reports are prone to bias. Clinician-based performance tests are limited by long administration times, restricted access, or inadequate validation. To close this gap, we developed and validated a performance-based measure of IADL, the Sydney Test of Activities of Daily Living in Memory Disorders (STAM).Design
Prospective cohort study (Sydney Memory and Ageing Study).Setting
Eastern Suburbs, Sydney, Australia.Participants
554 community-dwelling individuals (54% female) aged 76 and older with normal cognition, MCI, or dementia.Measurements
Activities of daily living were assessed with the STAM, administered by trained psychologists, and the informant-based Bayer-Activities of Daily Living Scale (B-ADL). Depressive symptoms were measured with the Geriatric Depression Scale (15-item version). Cognitive function was assessed with a comprehensive neuropsychological test battery. Consensus diagnoses of MCI and dementia were made independently of STAM scores.Results
The STAM showed high interrater reliability (r = 0.854) and test-retest reliability (r = 0.832). It discriminated significantly between the diagnostic groups of normal cognition, MCI, and dementia with areas under the curves ranging from 0.723 to 0.948. A score of 26.5 discriminated between dementia and nondementia with a sensitivity of 0.831 and a specificity of 0.864. Correlations were low with education (r = 0.230) and depressive symptoms (r = ?0.179), moderate with the B-ADL (r = ?0.332), and high with cognition (ranging from r = 0.511 to r = 0.594). The mean time to complete the STAM was 16 minutes.Conclusions
The STAM has good psychometric properties. It can be used to differentiate between normal cognition, MCI, and dementia and can be a helpful tool for diagnostic classification both in clinical practice and research. 相似文献13.

Objectives
This scoping study is the first step of a multiphase, international project aimed at designing a homecare robot that can provide functional support, track physical and psychological well-being, and deliver therapeutic intervention specifically for individuals with mild cognitive impairment.Design
Observational requirements gathering study.Participants and settings
Semistructured interviews were conducted with 3 participant groups: (1) individuals with memory challenges, mild cognitive impairment (MCI), or mild dementia (patients; n = 9); (2) carers of those with MCI or dementia (carers; n = 8); and (3) those with expertise in MCI or dementia research, clinical care, or management (experts; n = 16). Interviews took place at the university, at dementia care facilities or other workplaces, at participant's homes, or via skype (experts only).Measurements
Semistructured interviews were conducted, transcribed, and reviewed.Results
Several key themes were identified within the 4 topics of: (1) daily challenges, (2) safety and security, (3) monitoring health and well-being, and (4) therapeutic intervention.Conclusions
A homecare robot could provide both practical and therapeutic benefit for the mildly cognitively impaired with 2 broad programs providing routine and reassurance; and tracking health and well-being. The next phase of the project aims to program homecare robots with scenarios developed from these results, integrate components from project partners, and then test the feasibility, utility, and acceptability of the homecare robot. 相似文献14.

Objectives
Use of exercise technologies has benefits for community-dwelling older adults in terms of improved gait and balance. But research on the feasibility of use of exercise technologies in various geriatric health care settings is lacking. Hence, the current study examined the feasibility of implementing an exercise technology intended to augment rehabilitation in patients receiving post-acute care (PAC) in a skilled nursing facility (SNF). We focused on 3 indicators of feasibility: extent of usage (including predictors of more intense use), patients' acceptability of the technology, and limited efficacy.Design
Cross-sectional study with data from patients' electronic medical records (EMR), exercise technology portal, and patient interviews.Setting
SNF.Participants
A sample of post-acute patients (n = 237).Measurements
Sociodemographic and health-related variables, time spent using the technology, and 8 items of the Physical Activity Enjoyment Scale (PACES).Results
Average time spent using the technology varied greatly (range, 1–460 minutes). A regression analysis showed that patients who had a longer length of stay (β = .01, P < .05) and were younger (β = ?0.01, P < .05) spent significantly more time using the technology. Acceptability of technology was high among patients. Finally, patients who used the technology had lower 30-day rehospitalization rates.Conclusion
Exercise technology is feasible to use in supporting rehabilitation in patients receiving PAC in a SNF and seems to have beneficial effects. 相似文献16.

Objectives
The aim of the present study was to (1) evaluate a geriatric outpatient sample with the FRAIL scale; (2) investigate the psychometric properties of the scale; and (3) characterize different associations of the subdimensions of the scale with demographic and clinical data.Design
Cross-sectional observational study.Setting
Geriatric outpatient center a university-based hospital in São Paulo, Brazil.Participants
A total of 811 men and women aged 60 years or older evaluated between March 2015 and September 2015.Measurements
A translated version of the FRAIL scale was used to evaluate frailty. A review of sociodemographic data, medical records, medication, and laboratory data was conducted. A multivariate ordinal logistic regression model was used to investigate the association between frailty categories and clinical variables. Exploratory factor analysis and 2-parameter logistic item response theory was used to evaluate the psychometric properties of the FRAIL scale.Results
The sample was distributed as 13.6% robust, 48.7% prefrail, and 37.7% frail older adults. Most participants reported fatigue (72.3%). Frailty was associated with older age (P = .02), depression (P = .02), dementia (P < .001), and number of medications taken (P < .001). A 2-factor model of the FRAIL scale (“ambulation” and “resistance” namely physical performance; “fatigue,” “weight loss,” and “illnesses” namely health status) provided independent classifications of frailty status. Physical performance (ambulation and resistance) was strongly associated with higher age and dementia, whereas health status (fatigue, weight loss, and illnesses) was more associated with female sex and depression.Conclusions
Our results suggest the existence of 2 subdimensions of the scale, suggesting different pathways to frailty. Frailty was associated with older age, depression, dementia, and number of medications in this outpatient sample. 相似文献17.

Objective
This study investigated the potential of physical exercise habit as a lifestyle modification against cognitive and functional decline at the community level.Methods
A total of 454 community-dwelling Chinese older adults without dementia participated in the Hong Kong Memory and Ageing Prospective Study at baseline and follow-up at 5 years. Their cognitive and functional performances were assessed by the Cantonese version of the Mini-Mental State Examination (CMMSE) and the Chinese version of Disability Assessment in Dementia (DAD). Hierarchical multiple regression analyses were performed to examine whether physical exercise was a significant predictor of the follow-up CMMSE and DAD scores after controlling for the covariates. Subgroup analyses were performed with a group of 127 participants with mild cognitive impairment at baseline.Results
Physical exercise habit was a significant predictor for both the follow-up CMMSE scores and DAD scores. Participants with exercise habits of 5 years or more showed better cognitive and functional performances at follow-up. Participants who picked up exercise habits only after the baseline assessment also demonstrated better functioning at follow-up. The same patterns were observed in the subgroup analyses with the mild cognitive impairment group.Conclusion
Results suggested that prolonged exercise habit is required for positive effects on cognition to emerge, but benefits on functioning can be observed when individuals take up an exercise habit later in life or even after the beginning of cognitive decline. These findings are encouraging in promoting an exercise habit among older adults living in the community. 相似文献18.

Objectives
To survey the current methods used to ascertain dementia and mild cognitive impairment (MCI) in longitudinal cohort studies, to categorize differences in approaches and to identify key components of expert panel methodology in current use.Methods
We searched PubMed for the past 10 years, from March 6, 2007 to March 6, 2017 using a combination of controlled vocabulary and keyword terms to identify expert panel consensus methods used to diagnose MCI or dementia in large cohort studies written in English. From these results, we identified a framework for reporting standards and describe as an exemplar the clinical consensus procedure used in an ongoing study of elective surgery patients (the Successful Aging after Elective Surgery study).Results
Thirty-one articles representing unique cohorts were included. Among published methods, membership of experts panel varied significantly. There was more similarity in what types of information was use to ascertain disease status. However, information describing the diagnostic decision process and resolution of disagreements was often lacking.Conclusions
Methods used for expert panel diagnosis of MCI and dementia in large cohort studies are widely variable, and there is a need for more standardized reporting of these approaches. By describing the procedure in which our expert panel achieved consensus diagnoses, we hope to encourage the development and publication of well-founded and reproducible methods for diagnosis of MCI and dementia in longitudinal studies. 相似文献19.

Objectives
Identify contextual and implementation factors impacting the effectiveness of an organizational-level intervention to reduce preventable hospital readmissions from affiliated skilled nursing facilities (SNFs).Design
Observational study of the implementation of Interventions to Reduce Acute Care Transfers tools in 3 different cohorts.Setting
SNFs.Participants
SNFs belonging to 1 of 2 corporate entities and a group of independent SNFs that volunteered to participate in a Quality Improvement Organization (QIO) training program.Intervention
Two groups of SNFs received INTERACT II training and technical assistance from corporate staff, and 1 group of SNFs received training from QIO staff.Measurements
Thirty-day acute care hospital readmissions from Medicare fee-for-service claims, contextual factors using the Model for Understanding Success in Quality framework.Results
All 3 cohorts were able to deliver the INTERACT training program to their constituent facilities through regional events as well as onsite technical assistance, but the impact on readmission rates varied. Facilities supported by the QIO and corporation A were able to achieve statistically significant reductions in 30-day readmission rates. A review of contextual factors found that although all cohorts were challenged by staff turnover and workload, corporation B facilities struggled with a less mature quality improvement (QI) culture and infrastructure.Conclusions
Both corporations demonstrated a strong corporate commitment to implementing INTERACT II, but differences in training strategies, QI culture, capacity, and competing pressures may have impacted the effectiveness of the training. Proactively addressing these factors may help long-term care organizations interested in reducing acute care readmission rates increase the likelihood of QI success. 相似文献20.
