Abstract
BACKGROUND Caregivers for stroke survivors (CSS) suffer from long hours of care, limited support, and financial difficulties, which often affect their mental health. OBJECTIVES This study sought to determine the factors affecting psychological distress and sleep duration among CSS. METHODS We analyzed cross-sectional data from the 2013 Comprehensive Survey of the Living Conditions for Stroke Survivors and CSS. Linked data from 841 pairs of stroke survivors and CSS were extracted. Kessler's Psychological Distress scale (K6) was used to evaluate psychological distress. CSS who slept less than 5 hours per day were classified as having short sleep duration. Factors predictive of psychological distress and short sleep duration were evaluated using multivariable logistic regression analysis with the forward selection method. RESULTS The mean (SD) age of the CSS was 65.4 (12.5) years. A total of 5.6% of these caregivers presented with serious psychological distress, and 12.0% were sleep deprived. Serious psychological distress was associated with not having someone to consult with, having subjective symptoms within a few days, and having short sleep duration, while having their own houses reduced the risk of serious psychological distress. Furthermore, short sleep duration was associated with stroke survivors in long-term care levels 4 or 5, not having someone to consult with, participation in sponge baths as part of nursing care activities, and having serious psychological distress. CONCLUSIONS This nationwide survey identified several risk factors for psychological stress and sleep deprivation among CSS and suggests the need for multidimensional approaches to reduce their distress.

Abstract
Background Acute myocardial infarction (AMI) management strategies, involving treatment and post-care, are much more difficult for patients with dementia. This study investigated the factors influencing the use of invasive procedures and long-term care in the management strategies for AMI patients with dementia and the factors associated with these patients' survival. Methods This multilevel study combined information from two databases, namely later-stage elderly healthcare insurance and long-term care insurance claims, from 2013 to 2019. Of 214,963 individuals with dementia, we identified 13,593 patients with AMI. The primary outcomes were the use of invasive procedures for treatment and long-term care for post-care management. Survival outcomes were also measured over a 6-year period, adjusting for individual- and regional-level characteristics in multilevel models. Results A total of 1954 (14.38%) individuals received an invasive procedure during treatment, and 7850 (87.18%) used long-term care for post-care management after AMI. After multivariate adjustment, patients aged ≥ 85 years and women were less likely to receive invasive procedures and more likely to use long-term care. Patients undergoing invasive procedures had a lower use of long-term care. Better survival outcome was significantly associated with invasive management and long-term care, regardless of the type of care. Conclusion Age and sex determine the use of invasive procedures and long-term care after AMI among patients with dementia. AMI patients with dementia receiving invasive procedures and long-term care had better survival outcomes.

Abstract
This study aimed to evaluate caregiver burden and quality of life (QoL) and their predictors in family caregivers of dementia patients. A descriptive cross-sectional survey was carried out with a sample of 102 patients and their family caregivers. The Caregiver Burden Inventory (CBI) and Short Form-12 (SF-12) were used to collect data. CBI mean score was 37.97 ± 21.30. Mean scores of SF-12 sub-domains varied between 36.02 and 77.94 and were significantly lower as compared to normative means of the general population, excluding only the physical health subdomain. Among several patient and caregiver-related correlations, the number of medications and worse cognitive function of the patient, caregiver's age and having limited space at home were found as predictors of burden, whereas caregiver's chronic disease and having a limited space were predictors of QoL. Also, the burden and QoL were correlated. This study demonstrated a high burden and low QoL in dementia caregivers. In societies where caregivers are mostly informal such as that in Turkey, supportive systems should be established.

Abstract
Background Major reasons for long-term care insurance certification in Japan are stroke, dementia, and fracture. These diseases are reported to be associated with calcium intake. This study examined the association between calcium intake and impaired activities of daily living (ADL) using the data from NIPPON DATA90, consisting of representative sample of the Japanese population. Methods A population-based nested case-control study was performed. A baseline survey was conducted in 1990, followed by ADL surveys of individuals ≥65 years old in 2000. Individuals with impaired ADL and selected age- and sex-matched controls were then identified. We obtained 132 pairs. Calcium intake was energy-adjusted using the residual method. The association between calcium intake and impaired ADL was examined using conditional logistic regression models. To assess the accuracy of the estimates, we conducted bootstrap analyses. Results The adjusted odds ratios (ORs) for impaired ADL compared with the group with a calcium intake of <476 mg/day were 0.72 (95% confidence interval [CI], 0.37–1.40) for the 476–606 mg/day group and 0.44 (95% CI, 0.21–0.94) for the ≥607 mg/day group in 2000 (P for linear trend = 0.03). After the bootstrap analyses, the inverse relationship unchanged (median OR per 100-mg rise in calcium intake, 0.87 [1,000 resamplings]; 95% CI, 0.76–0.97). Conclusions After bootstrap analyses, calcium intake was inversely associated with impaired ADL 10 years after the baseline survey.

Abstract
PURPOSE (1) To identify measures used to evaluate the impact of caregiving among caregivers of persons with stroke, spinal cord injury, and amputation; and (2) to systematically evaluate their clinimetric properties reported in validation studies. MATERIALS AND METHODS Two separate systematic reviews (Embase, PsycINFO, CINAHL, Pubmed/Medline) were conducted. COSMIN guidelines were used to assess clinimetric properties and methodological quality of studies. RESULTS (1) 154 studies published between 2008 and May 2019 were included, in which 48 measures were used, mostly describing negative impact. Thirty measures were used only once and not further described. (2) In general, structural validity, internal consistency, and hypothesis testing were often investigated. Reliability, cross-cultural and criterion validity to a lesser extent, and scale development and content validity were rarely described. Tests of measurement error and responsiveness were exceptional. Most supporting evidence was found for the Zarit Burden Interview Short Form, Caregiver Burden Scale and Positive Aspects of Caregiving Questionnaire. CONCLUSIONS There is a wide variety of impact of caregiving measures. The present study provided a detailed overview of what is known about clinimetric characteristics of 18 different measures repeatedly used in research. The overview provides clinicians a guidance of appropriate measure selection. PROSPERO REGISTRATION CRD42018094796IMPLICATIONS FOR REHABILITATIONClinicians should be aware that information about measure development and clinimetric properties for most measures used to assess impact of informal caregiving is incomplete.Most supporting evidence was found for the Zarit Burden Interview Short Form, Caregiver Burden Scale and Positive Aspects of Caregiving Questionnaire.This overview of clinimetric properties provides clinicians guidance for selection of an appropriate measure.

Alzheimer's disease severity and its association with patient and caregiver quality of life in Japan: results of a community-based survey. BMC Geriatr 2018; 18:141.

Abstract
BACKGROUND Alzheimer's disease (AD) dementia, a progressive neurodegenerative disease, exerts significant burden upon patients, caregivers, and healthcare systems globally. The current study investigated the associations between AD dementia patient disease severity and health-related quality of life (HRQoL) of both patients (proxy report) and their caregivers living in Japan, as well as caregiving-related comorbidities such as depression. METHODS This cross-sectional study used self-reported data from caregivers of people diagnosed with AD dementia by a healthcare provider in Japan. Caregivers were identified via online panels and invited to participate in an online survey between 2014 and 2015. Caregivers completed survey items for themselves, in addition to providing proxy measures for patients with AD dementia for whom they were caring. Patient and caregiver HRQoL was measured using the EuroQoL 5-Dimension (EQ-5D). Additional outcomes for caregivers of AD dementia patients included the Patient Health Questionnaire (PHQ-9) of depressive symptomology, as well as comorbidities experienced since initiating caregiving for their AD dementia patients. These outcomes were examined as a function of AD dementia severity, as measured by long-term care insurance (LTCI) categories. Bivariate analyses between LTCI and outcomes were conducted using independent t-tests and chi-square tests. Multivariable analyses, controlling for potential confounders, were conducted using generalized linear models (GLMs) specifying a normal distribution. RESULTS Across 300 caregiver respondents, multivariable results revealed that increasing AD dementia severity was significantly associated with poorer patient and caregiver EQ-5D scores and a high proportion of caregivers (30.0%) reported PHQ-9 scores indicative of major depressive disorder (MDD). The most frequent comorbidities experienced after becoming caregivers of AD dementia patients included hypertension (12.7%) and insomnia (11.0%). Depression and other comorbidities did not differ significantly by patient severity. CONCLUSIONS The current study provides unique insight into the specific degree of incremental burden associated with increasing AD dementia severity among patients and caregivers alike. Importantly, greater disease severity was associated with poorer quality of life among both patients and caregivers. These results suggest that earlier detection and treatment of AD dementia may provide an opportunity to reduce the burden of disease for patients, caregivers, and society at large.

Abstract
BACKGROUND Dementia of Alzheimer's disease (AD) imposes burdens on patients, caregivers, and society. This cross-sectional study examined caregiver-reported history of disease onset and AD dementia to inform efforts promoting early disease detection and diagnosis. METHODS An online survey collected self-reported cross-sectional data - demographic characteristics, diagnosis, treatment experiences, and other information on disease detection, diagnosis, and treatment - from caregivers of patients with AD dementia. These characteristics were examined as a function of AD dementia severity. RESULTS Three hundred patients with AD dementia were trichotomized by long-term care insurance levels reported by caregivers: 12.3% (n=37) as low severity, 63.7% (n=191) as medium severity, and 24.0% (n=72) as high severity. The Short-Memory Questionnaire and patient dependency scores both varied significantly across severity groups. AD dementia symptoms were most frequently first detected by a caregiver (58.7%) or the patient's family (45.7%). However, in 13.7% of cases, symptoms were detected by a health care provider during a routine visit. Memory problems were the most frequent first symptoms (77.3%), followed by repetition (55.7%). Patients (73.7%) were taking symptomatic treatment such as acetylcholinesterase inhibitors or memantine. High-severity patients were older, had been diagnosed with AD dementia for a longer time, had more frequent reports of memory problems as the first symptoms detected, and required more hours of care per day, compared with low-severity patients. CONCLUSION Caregivers and families play an integral role in the identification of AD dementia patients, with memory problems being common first symptoms noticed by caregivers that led to a diagnosis of AD dementia. These results provide novel insight into the detection, diagnosis, and treatment of AD dementia in Japan and how these factors differ across the spectrum of disease severity.

Cost-effectiveness analysis of shunt surgery for idiopathic normal pressure hydrocephalus based on the SINPHONI and SINPHONI-2 trials. Acta Neurochir (Wien) 2017; 159:995-1003. [PMID: 28251346 DOI: 10.1007/s00701-017-3115-2] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2016] [Accepted: 02/09/2017] [Indexed: 10/20/2022]
Abstract
BACKGROUND We showed that ventriculoperitoneal (VP) shunt and lumboperitoneal (LP) shunt surgeries are beneficial for patients with idiopathic normal pressure hydrocephalus (iNPH) in the Study of Idiopathic Normal Pressure Hydrocephalus on Neurological Improvement (SINPHONI; a multicenter prospective cohort study) and in SINPHONI-2 (a multicenter randomized trial). Although therapeutic efficacy is important, cost-effectiveness analysis is equally valuable. METHODS Using both a set of assumptions and using the data from SINPHONI and SINPHONI-2, we estimated the total cost of treatment for iNPH, which consists of medical expenses (e.g., operation fees) and costs to the long-term care insurance system (LCIS) in Japan. Regarding the natural course of iNPH patients, 10% or 20% of patients on each modified Rankin Scale (mRS) show aggravation (aggravation rate: 10% or 20%) every 3 months if the patients do not undergo shunt surgery, as described in a previous report. We performed cost-effectiveness analyses for the various scenarios, calculating the quality-adjusted life year (QALY) and the incremental cost-effective ratio (ICER). Then, based on the definition provided by a previous report, we assessed the cost-effectiveness of shunt surgery for iNPH. RESULTS In the first year after shunt surgery, the ICER of VP shunt varies from 29,934 to 40,742 USD (aggravation rate 10% and 20%, respectively) and the ICER of LP shunt varies from 58,346 to 80,392 USD (aggravation rate 10% and 20%, respectively), which indicates that the shunt surgery for iNPH is a cost-effective treatment. In the 2nd postoperative year, the cost to the LCIS will continue to decrease because of the lasting improvement of the symptoms due to the surgery. The total cost for iNPH patients will show a positive return on investment in as soon as 18 months (VP) and 21 months (LP), indicating that shunt surgery for iNPH is a cost-effective treatment. CONCLUSIONS Because the total cost for iNPH patients will show a positive return on investment within 2 years, shunt surgery for iNPH is a cost-effective treatment and therefore recommended. The SINPHONI-2 study was registered with the University Hospital Medical Information Network Clinical Trials registry: UMIN000002730) SINPHONI was registered with ClinicalTrials.gov, no. NCT00221091.

Abstract
AIM To investigate the association of retinal vascular changes with a risk of dementia in longitudinal population-based study. METHODS We performed a nested case-control study of 3,718 persons, aged 40-89 years, enrolled between 1983 and 2004. Retinal vascular changes were observed in 351 cases with disabling dementia (average period before the onset, 11.2 years) and in 702 controls matched for sex, age, and baseline year. Incidence of disabling dementia was defined as individuals who received cares for disabilities including dementia-related symptoms and/or behavioral disturbance. Conditional logistic regression analysis was used to calculate odds ratio (OR) and multivariable adjusted OR (Models 1 and 2) for incidence of disabling dementia according to each retinal vascular change. Regarding confounding variables, Model 1 included overweight status, hypertension, hyperglycemia, dyslipidemia, and smoking status, whereas Model 2 also included incidence of stroke prior to disabling dementia for further analysis. RESULTS The proportion of cases (controls) with retinal vascular changes was 23.1 (15.7)% for generalized arteriolar narrowing, 7.7 (7.5)% for focal arteriolar narrowing, 15.7 (11.8)% for arteriovenous nicking, 10.5 (9.3)% for increased arteriolar wall reflex, and 11.4 (9.8)% for any other retinopathy. Generalized arteriolar narrowing was associated with an increased risk of disabling dementia: crude OR, 1.66 (95% confidence interval, 1.19-2.31); Model 1: OR, 1.58 (1.12-2.23); Model 2: OR, 1.48 (1.04-2.10). The number of retinal abnormalities was associated in a dose-response manner with the risk. CONCLUSION Generalized arteriolar narrowing and total number of retinal abnormalities may be useful markers for identifying persons at higher risks of disabling dementia.

Abstract
INTRODUCTION We studied the mortality risk of long term and new antipsychotic drug use in Alzheimer's disease (AD) patients in Japan to determine improved treatment protocols. METHODS This 24-week prospective cohort study included 10,079 Japanese AD patients (female, 69%; average age, 81 years) under routine clinical care in 357 medical sites. The antipsychotic medication history was varied (63.7% were long-term users). Mortality rates and odds ratio were analyzed (initial 10 weeks and from 11-24 weeks). RESULTS The antipsychotic exposed group with shorter treatment periods had a higher mortality risk compared to controls. The newly prescribed users (antipsychotic treatment started during the follow-up) showed increased mortality (9.4% during the 11-24 week period). CONCLUSIONS New use of antipsychotic drugs represents a distinct risk for mortality; those on long-term antipsychotic therapy seem to be at less risk. The warning issued 10 years earlier on antipsychotics use for AD patients should be reviewed.

Abstract
BACKGROUND Psychological stress associated with caregiving is thought to underlie the high incidence of hypertension, ischemic heart disease, and mortality, as well as reduced immune function, among caregivers of dementia patients. Here, we examined the effects of periodic leisure activities performed by caregivers of dementia patients with care recipients at home on perceived care burden and levels of stress hormones. METHODS Participants were 42 caregivers aged ≥ 65 years of patients diagnosed with Alzheimer's dementia. They were randomly assigned to intervention and non-intervention groups. The intervention group underwent a leisure activity program (30 min/3 times/week for 24 weeks) with the care recipient, and the control group underwent normal care activities. RESULTS The Zarit Burden Interview (ZBI) score, a subjective indicator of care burden, significantly decreased after intervention in the intervention group (p < 0.05), whereas no difference was observed in the control group. No significant changes were observed in adrenaline, noradrenaline, dopamine, and cortisol levels in both groups. CONCLUSIONS The lack of changes in stress hormone levels despite a decrease in subjective care burden in the intervention group might be explained by the effects of the chosen leisure activity on the neuroendocrine system. Our findings suggest that periodic leisure activities can reduce perceived care burden among caregivers of dementia patients. However, in order to evaluate accurately the effects of leisure activities of the present study, long-term follow-up of both caregivers and care recipients is necessary.

Abstract
BACKGROUND The behavioural and psychological symptoms of dementia (BPSD) caused by Alzheimer's disease (AD) can burden caregivers. Group homes (GH), small nursing homes, for the elderly with dementia are institutions commonly run by the public long-term care insurance system in Japan. The purpose of this study was to compare the prevalence of BPSD of AD, as evaluated by the Behavioural Pathology in Alzheimer's Disease Rating Scale, between GH patients and community residents. METHODS A total of 74 patients with AD were enrolled: 37 were patients institutionalized in GH (Hachinski score < 5) and 37 were demographic-matched community residents undergoing treatment at the Osaki-Tajiri SKIP Center. There were no significant differences in mean age (81.4 vs 81.1 years, P = 0.816), mean educational level (7.7 vs 8.0 years, P = 0.497), sex (women/men: 30/7 vs 30/7, P = 1.000) and mean Mini-Mental State Examination scores (14.1 vs 14.1, P = 0.950) between the two groups. Care level (range: 0.5-5.0, slight to bedridden), activities of daily living care level (range: 1-7, almost normal to severe), and the presence or absence BPSD based on the domains of the Behavioural Pathology in Alzheimer's Disease Rating Scale were compared. RESULTS GH patients had a significantly higher care level (P < 0.05) and activities of daily living care level (P < 0.05) but had fewer symptoms of BPSD (P < 0.05) than community residents. When the activities of daily living care level was controlled, GH patients had significantly fewer symptoms than community residents in Aggressiveness (21% vs 50%; χ2 = 4.5, P = 0.035), Affective disturbances (13% vs 42%; χ2 = 5.1, P = 0.023), and Anxieties and phobias (4% vs 46%; χ2 = 11.1, P = 0.001). CONCLUSIONS GH run by the long-term care insurance system appear to be effective in improving environmental factors for moderate AD patients and reducing Aggressiveness, Affective disturbances, and Anxieties and phobias.

Abstract
This study examined the incidence, neuropsychological characteristics and risk factors of cognitive impairment 3 months after stroke in China. Five regions that differed in geography and economy in China were selected. Patients from the hospitals located in the five regions were prescreened at admission, and the demographic data, vascular risk factors and clinical characteristics of stroke were obtained. A battery of cognitive-specific domain tests was performed in the patients who failed to pass cognitive screening 3 months post stroke. Patients were diagnosed as having post-stroke cognitive impairment (PSCI) or no cognitive impairment (NCI) based on the results of the neuropsychological tests. Univariate analysis was performed for suspect risk factors, and significant variables were entered in multivariable logistic regression analysis. Our results showed that a total of 633 patients were recruited 3 months after stroke; complete cognitive tests were performed in 577 of the stroke patients. The incidence of PSCI in these Chinese patients was 30.7%. There were 129 (22.4%) patients with visuospatial impairment, 67 (11.6%) with executive impairment, 60 (10.4%) with memory impairment and 18 (3.1%) with attention impairment. The risk factors associated with PSCI were older age (odds ratio [OR] 1.76, 95% confidence interval [CI] 1.20-2.58), low education level (OR 2.45, 95% CI 1.65-3.64), depressive symptom (OR 1.69, 95% CI 1.09-2.61), obesity (OR 2.57, 95% CI 1.41-4.71), stroke severity 3 months post stroke (OR 1.62, 95%CI 1.10-2.37) and cortex lesion (OR 1.55, 95% CI 1.04-2.31). It was concluded that PSCI occurs commonly 3 months after first-ever stroke in Chinese patients. Visuospatial ability may be the most frequently impaired cognitive domain for the patients with stroke. The critical risk factors of PSCI are older age, low education level, depressive symptom, obesity, stroke severity 3 months post stroke and cortex lesion.

Abstract
BACKGROUND Mortality risk tends to be higher among elderly individuals with higher serum adiponectin levels. The objective of this study was to clarify whether the relationship between adiponectin and a higher risk of disability or death can be explained by physical function, bone mineral density, depression, and malnutrition. METHODS We analyzed 505 individuals who underwent comprehensive geriatric assessment and who agreed to provide information on long-term care insurance. The endpoint was the composite outcome of death and incident disability defined as a first certification for any level of care need. Relationships between adiponectin and incident disability or death were estimated using the Cox proportional hazards model. RESULTS During 6 years of follow-up, 179 incident disabilities or deaths occurred. Among them, 20 and 23 died with and without disability, respectively. The risk of incident disability or death was significantly higher among participants with adiponectin greater than or equal to 22.4 (90%) than 8.0 or less (25%) mg/L (Hazard ratio: 95% confidence interval, 1.92: 1.01-3.64) in the model adjusted for age, sex, and metabolic risk factors. Adjustment for N-terminal pro-B-type natriuretic peptide and nutritional status did not substantially alter this risk estimate, although the association ceased to be statistically significant. Adjustment for physical function did attenuate the relationship, however, which ceased to be apparent upon exclusion of disability or death occurring within 3 years of follow-up. CONCLUSION The relationship between adiponectin and the composite outcome of incident disability and death was at least partly explained by reduced physical function and wasting in participants with higher adiponectin levels.

Abstract
Background Robotic devices are expected to be widely used in various applications including support for the independent mobility of the elderly with muscle weakness and people with impaired motor function as well as support for nursing care that involves heavy laborious work. We evaluated the effects of a hybrid assistive limb robot suit on the gait of stroke patients undergoing rehabilitation. Methods The study group comprised 16 stroke patients with severe hemiplegia. All patients underwent gait training. Four patients required assistance, and 12 needed supervision while walking. The stride length, walking speed and physiological cost index on wearing the hybrid assistive limb suit and a knee-ankle-foot orthosis were compared. Results The hybrid assistive limb suit increased the stride length and walking speed in 4 of 16 patients. The patients whose walking speed decreased on wearing the hybrid assistive limb suit either had not received sufficient gait training or had an established gait pattern with a knee-ankle-foot orthosis using a quad cane. The physiological cost index increased after wearing the hybrid assistive limb suit in 12 patients, but removal of the suit led to a decrease in the physiological cost index values to equivalent levels prior to the use of the suit. Conclusions Although the hybrid assistive limb suit is not useful for all hemiplegic patients, it may increase the walking speed and affect the walking ability. Further investigation would clarify its indication for the possibility of gait training.

Abstract
The present meta-analysis integrates the results from 168 empirical studies on differences between caregiving spouses, adult children, and children-in-law. Spouses differ from children and children-in-law significantly with regard to sociodemographic variables; also, they provide more support but report fewer care recipient behavior problems. Spouse caregivers report more depression symptoms, greater financial and physical burden, and lower levels of psychological well-being. Higher levels of psychological distress among spouses are explained mostly--but not completely--by higher levels of care provision. Few differences emerge between children and children-in-law, but children-in-law perceive the relationship with the care recipient as less positive and they report fewer uplifts of caregiving.

Abstract
AIM The aim of this study was to investigate whether peripheral arterial disease (PAD) is predictive of disability and whether the relationship between PAD and disability can be fully explained by baseline physical functions. METHODS We followed for five years 783 Japanese aged 70 years or older without a disability at baseline in 2003. We defined participants certificed as requiring long-term care as having incident disability. The hazard ratio (HR) and 95% confidence interval (95% CI) for incident disability were calculated using the Cox proportional hazards model. RESULTS After adjusting for possible confounders other than physical function, the HR of incident disability among participants with PAD was 1.86 (95%CI: 1.06 to 3.26).Although the risk was attenuated (HR=1.63, 95%CI: 0.92 to 2.86) after adding baseline physical function as a covariate, the HR was still high. Furthermore, the relation was not statistically significant, but the group with higher physical function and PAD also had a higher HR of incident disability than those who had higher physical function without PAD. CONCLUSION PAD is an important predictor of disability even if the level of baseline physical function is high.
