RESUMO

Accumulating research suggests that individuals with Mild Cognitive Impairment (MCI) experience subtle functional changes, but that available functional assessment tools are insensitive to this. To address this gap, we describe the development and validation of the self-report, "Healthy Brain Ageing Functional Assessment Questionnaire" (HBA-FAQ). We examined the factor structure and psychometric properties of the HBA-FAQ in 503 participants with normal cognition, subjective cognitive decline (SCD), MCI or dementia. Our results found the HBA-FAQ to have good reliability, validity and stronger discriminative ability between healthy control participants and those with SCD (0.734, p = .001), MCI (0.666, p = .012) and dementia (0.798, p < .001) compared to a widely-used instrumental activities of daily living screener. In conclusion, the HBA-FAQ is a valid, reliable self-report tool, providing an efficient and sensitive approach to identifying subtle changes in daily functioning in older people at risk of dementia.

RESUMO

Brain health as expressed in our mental health and occurrence of specific disorders such as dementia and stroke is vitally important to quality of life, functional independence, and risk of institutionalization. Maintaining brain health is, therefore, a societal imperative, and public health challenge, from prevention of acquisition of brain disorders, through protection and risk reduction to supporting those with such disorders through effective societal and system approaches. To identify possible mechanisms that explain the differential effect of potentially modifiable risk factors, and factors that may mitigate risk, a life course approach is needed. This is key to understanding how poor health can accumulate from the earliest life stages. It also allows us to integrate and investigate key material, behavioral, and psychological factors that generate health inequalities within and across communities and societies. This review provides a narrative on how brain health is intimately linked to wider health determinants, thus importance for clinicians and societies alike. There is compelling evidence accumulated from research over decades that socioeconomic status, higher education, and healthy lifestyle extend life and compress major morbidities into later life. Brain health is part of this, but collective action has been limited, partly because of the separation of disciplines and focus on highly reductionist approaches in that clinicians and associated research have focused more on mitigation and early detection of specific diseases. However, clinicians could be part of the drive for better brain health for all society to support life courses that have more protection and less risk. There is evidence of change in such risks for conditions such as stroke and dementia across generations. The evidence points to the importance of starting with parental health and life course inequalities as a central focus.

RESUMO

OBJECTIVE: The purpose of this study was to analyze the relative and absolute reliability of assessment tests addressing body structure and function and activity in older adults with dementia. METHODS: Medline, Embase, Web of Science, The Cochrane Library, and Scielo were searched from inception until March 2021. Two independent reviewers performed the selection process based on titles, abstracts, and full text. Reliability studies of assessment tests in older adults with dementia were included. Methodological quality of the studies was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments Risk of Bias checklist. Relative reliability was analyzed using the intraclass correlation coefficient (ICC) interpreted based on Munro classification. Absolute reliability was analyzed using the minimal detectable change (MDC) and standard error of measurement. RESULTS: Fifteen studies involving a total of 560 older adults with dementia were included. Nineteen assessment tests were identified: 13 addressing body structure and function (muscle strength, postural balance, cardiorespiratory fitness) and 6 addressing activity (walking and mobility). Studies determined test-retest and interrater reliability. Fifteen studies evaluated relative reliability using the ICC, with values ranging from no or small correlation to very high correlations. Ten studies evaluated absolute reliability using the MDC or standard error of measurement or both. CONCLUSION: Relative reliability of the assessment tests for body structure and function and activity was high to very high based on ICCs, demonstrating good reproducibility. Regarding absolute reliability, the analysis of the MDC values revealed the need for substantial change to determine that a real change had occurred. Future investigations should consider the type of dementia and standardization of verbal encouragement during the assessment. IMPACT: This review identified the good reproducibility of assessment tests of body structure and function (muscle strength, postural balance, cardiorespiratory fitness) and activity (walking and mobility) domains in older adults with dementia. Clinically important values may differ when older adults with dementia of diverse etiologies are analyzed together and older adults specifically with Alzheimer disease. Identifying the type of dementia, analyzing types of dementia separately, and standardizing verbal commands during the execution of tests is of considerable clinical importance for this population of older adults.

RESUMO

BACKGROUND: Vision and hearing impairments often co-exist with dementia, and all are independently associated with limitations in daily activities. Our aim was to examine the association of dual sensory impairment with functional limitations, and further examine the combined estimated association of sensory impairment and dementia with these functional limitations. METHODS: Cross-sectional analysis of the National Health and Aging Trends Study (NHATS), a population-based cohort of Medicare beneficiaries, was performed. Participants were selected from the 2015 round. Survey weighted Poisson regression models adjusted for dementia, demographics, and health status variables examined the association of self-reported dual sensory impairment (no sensory impairment, single sensory impairment, dual sensory impairment) with scores of limitations in mobility, self-care, and household activities. Models were repeated to take into account the combined effects of dual sensory impairment and dementia. RESULTS: Overall, 7124 participants representative of Medicare beneficiaries 65 years or older were included. Of them, 43.9% were 75 years or older and 55.3% were female. Older adults with dual sensory impairment had greater limitations with mobility (prevalence rate ratio [PRR] = 1.45, 95% CI = 1.28-1.63), self-care (PRR = 1.41, 95% CI = 1.25-1.59), and household activities (PRR = 1.54, 95% CI = 1.37-1.72) compared with those without sensory impairment. They also had greater limitations than those with a single sensory impairment across the different activity categories. In models taking into account the combined estimated effect of both sensory impairment and dementia, those with dual sensory impairment and dementia had greater limitations than those without sensory impairment or dementia in each category (mobility: PRR = 1.85, 95% CI = 1.59-2.14, self-care: PRR = 1.86, 95% CI = 1.59-2.18, household: PRR = 2.41, 95% CI = 2.09-2.77). CONCLUSIONS: Older adults with dual sensory impairment had greater functional limitations compared with those without sensory impairment and those with a single sensory impairment. Strategies to improve visual and/or hearing function (e.g., sensory aids, rehabilitation) could potentially help prevent or minimize disability, even among those with dementia.

RESUMO

BACKGROUND: Many patients with Alzheimer's disease and related dementia (ADRD) have chronic hepatitis C due to the high prevalence of both conditions among elderly populations. Direct-acting antivirals (DAAs) are effective in treating hepatitis C virus (HCV). However, the complexity of ADRD care may affect DAA use and outcomes among patients with HCV and ADRD. Little information exists on uptake of DAAs, factors associated with DAA use, and health benefits of DAAs among patients with HCV and ADRD. OBJECTIVE: To examine use and survival benefits of DAAs in Medicare patients with HCV and ADRD. METHODS: The study included Medicare patients with HCV between 2014 and 2017. We estimated Cox proportional hazards regressions to examine the association between having ADRD and DAA use, and the relation between DAA use and survival among patients with HCV and ADRD. RESULTS: The adjusted hazard of initiating a DAA was 50% lower in patients with ADRD than those without ADRD (adjusted HR = 0.50, 95% CI: 0.46-0.54). The hazard of DAA use among ADRD patients with behavioral disturbances was 68% lower than non-ADRD patients (adjusted HR = 0.32, 95% CI: 0.28-0.37). DAA treatment was associated with a significant reduction in mortality among ADRD patients (adjusted HR = 0.52, 95% CI: 0.44-0.61). CONCLUSION: The rate of DAA treatment in patients with HCV and ADRD was low, particularly among those with behavioral disturbance. The survival benefits of DAA treatment for patients with ADRD were substantial.

RESUMO

BACKGROUND/OBJECTIVES: Briefer measures of symptoms and functional limitations may reduce assessment burden and facilitate monitoring populations of persons with dementia (PWD). DESIGN: Prospective follow-up study. SETTING: University-based dementia care management program. PARTICIPANTS: 1,091 PWD. MEASUREMENTS: We assessed cognition (Mini Mental State Examination (MMSE)-11 tasks), neuropsychiatric symptom severity (Neuropsychiatric Inventory Questionnaire Severity Scale (NPIQ-S)-12 items), and functional ability (Activities of Daily Living (ADL)-6 items; Functional Activities Questionnaire (FAQ)-10 items). Item response theory was used to select subsets of items by identifying low item discrimination (<1.50), poor item fit (χ2 ), local dependence (LD), and with difficulty similar to other items. We estimated correlations between original and shorter scales and compared their associations with mortality. We added two symptoms (trouble swallowing, coughing when eating) reflecting late-stage dementia complications, created a multi-dimensional dementia assessment composite, and examined its association with mortality. RESULTS: Five MMSE tasks were eliminated: two with low discrimination, two with difficulty similar to other items, and one with poor fit. The remaining tasks were correlated with the full MMSE at r = 0.82. We retained three ADLs that were correlated with the total ADL set at r = 0.95 and kept five FAQ items that were not LD (correlation with full FAQ, r = 0.97). Associations with mortality were similar between the longer and shorter scales. A higher score on the composite (range 0-100) indicates worse dementia impact and was associated with mortality (hazard ratio (HR) per scale point: 1.03 (1.02-1.04)). CONCLUSION: These brief assessments and dementia composite may reduce administration time while preserving validity.

RESUMO

BACKGROUND: People living in group situations or with dementia are more vulnerable to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Older people and those with multimorbidity have higher mortality if they become infected than the general population. However, no systematic study exists of COVID-19-related outcomes in older inpatients in psychiatric units, who comprise people from these high-risk groups. We aimed to describe the period prevalence, demographics, symptoms (and asymptomatic cases), management, and survival outcomes of COVID-19 in the older inpatient psychiatric population and people with young-onset dementia in five National Health Service Trusts in London, UK, from March 1 to April 30, 2020. METHODS: In this retrospective observational study, we collected demographic data, mental health diagnoses, clinical diagnosis of COVID-19, symptoms, management, and COVID-19-related outcome data of inpatients aged 65 years or older or with dementia who were already inpatients or admitted as inpatients to five London mental health Trusts between March 1 and April 30, 2020, and information about available COVID-19-related resources (ie, testing and personal protective equipment). Patients were determined to have COVID-19 if they had a positive SARS-CoV-2 PCR test, or had relevant symptoms indicative of COVID-19, as determined by their treating physician. We calculated period prevalence of COVID-19 and analysed patients' characteristics, treatments, and outcomes. FINDINGS: Of 344 inpatients, 131 (38%) were diagnosed with COVID-19 during the study period (period prevalence 38% [95% CI 33-43]). The mean age of patients who had COVID-19 was 75·3 years (SD 8·2); 68 (52%) were women and 47 (36%) from ethnic minority groups. 16 (12%) of 131 patients were asymptomatic and 121 (92%) had one or more disease-related comorbidity. 108 (82%) patients were compulsorily detained. 74 (56%) patients had dementia, of whom 13 (18%) had young-onset dementia. On average, sites received COVID-19 testing kits 4·5 days after the first clinical COVID-19 presentation. 19 (15%) patients diagnosed with COVID-19 died during the study period, and their deaths were determined to be COVID-19 related. INTERPRETATION: Patients in psychiatric inpatient settings who were admitted without known SARS-CoV-2 infection had a high risk of infection with SARS-CoV-2 compared with those in the community and had a higher proportion of deaths from COVID-19 than in the community. Implementation of the long-standing policy of parity of esteem for mental health and planning for future COVID-19 waves in psychiatric hospitals is urgent. FUNDING: None.

RESUMO

PURPOSE: For persons who are at risk for, or living with, dementia exercise is recommended, yet many become or remain inactive. Exercise providers play a vital role in promoting and facilitating exercise in these groups by recognizing and being responsive to the needs of persons with mild cognitive impairment (MCI) or dementia in exercise programming. The objective of this study was to explore the experiences, perceptions, and needs of community exercise providers regarding dementia. MATERIALS & METHODS: Five focus groups were held with community exercise providers (n = 30) who deliver exercise to older adults (≥55 years) in municipal, non-profit, for profit, or academic settings. RESULTS: Three themes were developed: (1) Unique experiences and diverse perceptions: suggests unique personal experiences with MCI and dementia inform distinct perceptions of dementia; (2) Dementia-Inclusive Practices: learning as you go and adapting for the individual: reflects exercise providers' approaches to recognizing and accommodating individuals' unique abilities and preferences; (3) Training and Best Practices, with Flexibility: identifies exercise providers' desires for MCI- and dementia-specific knowledge and training strategies, which need to recognize dementia heterogeneity between and within persons over time. CONCLUSIONS: These findings highlight a willingness of exercise providers to support dementia-inclusive exercise, but recognize they have minimal training and lack educational resources to do so. Formal training resources may enhance exercise accessibility and participation for persons with MCI or dementia.

RESUMO

The temperature of the indoor environment is important for health and wellbeing, especially at the extremes of age. The study aim was to understand the relationship between self-reported thermal sensation and extremity skin temperature in care home residents with and without dementia. The Abbreviated Mental Test (AMT) was used to discriminate residents to two categories, those with, and those without, dementia. After residents settled and further explanation of the study given (approximately 15 min), measurements included: tympanic membrane temperature, thermal sensation rating and infrared thermal mapping of non-dominant hand and forearm. Sixty-nine afebrile adults (60-101 years of age) were studied in groups of two to five, in mean ambient temperatures of 21.4-26.6 °C (median 23.6 °C). Significant differences were observed between groups; thermal sensation rating (p = 0.02), tympanic temperature (p = 0.01), fingertip skin temperature (p = 0.01) and temperature gradients; fingertip-wrist p = 0.001 and fingertip-distal forearm, p = 0.001. Residents with dementia were in significantly lower air temperatures (p = 0.001). Although equal numbers of residents per group rated the environment as 'neutral' (comfortable), resident ratings for 'cool/cold' were more frequent amongst those with dementia compared with no dementia. In parallel, extremity (hand) thermograms revealed visual temperature demarcation, variously across fingertip, wrist, and forearm commensurate with peripheral vasoconstriction. Infrared thermography provided a quantitative and qualitative method to measure and observe hand skin temperature across multiple regions of interest alongside thermal sensation self-report. As an imaging modality, infrared thermography has potential as an additional assessment technology with clinical utility to identify vulnerable residents who may be unable to communicate verbally, or reliably, their satisfaction with indoor environmental conditions.

RESUMO

BACKGROUND: There is currently no gold standard instrument for assessing pain in severely cognitively impaired adults who are unable to provide self-report. AIMS: To determine interrater reliability of the PACSLAC and PAINAD in assessing pain behaviors in patients with the same pain stimulus, determine the consistency of the reliable changes between and within the instruments and assess nurse preference for either instrument. DESIGN: A single-group, within-subjects repeated-measures design was implemented. SETTING: The study took place in a small suburban hospital. PARTICIPANTS/SUBJECTS: Pain levels were observed at 24, 48, and 72 hours postsurgery using two instruments: Pain Assessment Checklist for Seniors with Limited Ability to Communicate (PACSLAC) and Pain Assessment in Advanced Dementia Scale (PAINAD). These instruments were selected because they are among the most commonly recommended tools for clinical use. Interrater reliability was analyzed along with reliable changes in pain for each period, and the study concluded with the nurse raters completing a preference survey. METHODS: A convenience sample of 30 patients was used with a diagnosis of severe dementia rendering the patient unable to reliably express pain, 60+ years of age, recovering from hip fracture surgery. RESULTS: Greater interrater reliability was found for the PACSLAC, with reliable change potentially affected by the type and level of pain medication. The nurses' preference for the tool was split. CONCLUSIONS: The results of this study indicate that the PACSLAC may be the more reliable tool over the PAINAD; however, rater training and familiarity with the tool is critical.

RESUMO

OBJECTIVE: This paper reports on the valuation of quality-of-life states in the Alzheimer's Disease Five Dimensions (AD-5D) instrument in a representative sample of the general population in Australia using the discrete-choice experiment with duration (DCETTO) elicitation technique. METHOD: A DCE with 200 choice sets of two quality-of-life (QoL) state-duration combinations blocked into 20 survey versions, with ten choice sets in each version, was designed and administered online to a sample representative of the Australian population. Two additional choice sets comprising internal consistency and dominance checks were included in each survey version. A range of model specifications investigating preferences with respect to duration and interactions between AD-5D dimension levels were estimated. Utility weights were developed, with estimated coefficients transformed to the 0 (being dead) to 1 (full health) scale, suitable for the calculation of quality-adjusted life-year (QALY) weights for use in economic evaluation. RESULTS: In total, 1999 respondents completed the choice experiment. Overall, respondents were slightly better educated and had higher annual incomes than the Australian general population. The estimation results from different specifications and models were broadly consistent with the monotonic nature of the AD-5D: utility increased with increased life expectancy and decreased as the severity level for each dimension worsened. A utility value set was generated for the calculation of utilities for all QoL states defined by the AD-5D descriptive system. CONCLUSION: The DCE-based utility value set is now available to use to generate QALYs for the economic evaluation of treatments and interventions targeting people with dementia and/or their family caregivers.

RESUMO

PURPOSE: To determine the association of retinal thickness with cognitive function in Japanese persons. DESIGN: Cross-sectional, population-based survey. PARTICIPANTS: A total of 1293 Japanese persons aged 65 to 86 years who resided in the Saku area in the Japan Public Health Center-Based Prospective Study participated in the eye and mental health screening. METHODS: Participants underwent comprehensive ophthalmic assessment, including fundus photography, measurement of intraocular pressure, and determination of refraction status. We assessed the thickness of the macular retinal nerve fiber layer (mRNFL), ganglion cell-inner plexiform layer (GC-IPL), and ganglion cell complex (GCC, which includes the retinal nerve fiber layer and GC-IPL), and the full thickness in the macula and peripapillary retinal nerve fiber layer (ppRNFL) using spectral-domain (SD) OCT. Cognitive tests consisted of the Mini-Mental State Examination, Wechsler Memory Scale Revised logical memory I/II subtest, clock drawing test, and Clinical Dementia Rating Scale. These were used to designate the participants in the following 3 groups: Normal, those with mild cognitive impairment (MCI), and those with dementia. Multivariable logistic regression models were used to analyze associations between retinal thickness and cognitive function after adjusting potential confounding factors. MAIN OUTCOME MEASURES: Association of retinal thickness with cognitive function. RESULTS: Among the 1293 potential subjects, 114 were excluded for a diagnosis of depression, 64 were excluded for retinal disease, and 140 were excluded for scanning errors or suboptimal OCT images. The remaining 975 participants (mean age, 73.2 years) were included in this analysis. Significant differences were found in the 3 groups in all layers and GCC thickness, but not in ppRNFL thickness. After adjusting for age, sex, educational status, and refraction, full macular thickness and GCC thickness were inversely associated with the presence of dementia, but ppRNFL thickness was not. Furthermore, GC-IPL, GCC, and full macular thicknesses were all associated with the presence of dementia in the inferior sectors. CONCLUSIONS: Macular thickness was associated with the presence of dementia, but ppRNFL was not. Our results suggest that OCT measurements of the macula could be superior to those of the ppRNFL in assessing neurodegenerative changes and a potentially useful diagnostic biomarker of cognitive function.

RESUMO

BACKGROUND: Gait impairments contribute to falls in people with dementia. In this study, we used a vision-based system to record episodes of walking over a 2-week period as participants moved naturally around their environment, and from these calculated spatiotemporal, stability, symmetry, and acceleration gait features. The aim of this study was to determine whether features of gait extracted from a vision-based system are associated with falls, and which of these features are most strongly associated with falling. METHODS: Fifty-two people with dementia admitted to a specialized dementia unit participated in this study. Thirty different features describing baseline gait were extracted from Kinect recordings of natural gait over a 2-week period. Baseline clinical and demographic measures were collected, and falls were tracked throughout the participants' admission. RESULTS: A total of 1,744 gait episodes were recorded (mean 33.5 ± 23.0 per participant) over a 2-week baseline period. There were a total of 78 falls during the study period (range 0-10). In single variable analyses, the estimated lateral margin of stability, step width, and step time variability were significantly associated with the number of falls during admission. In a multivariate model controlling for clinical and demographic variables, the estimated lateral margin of stability (p = .01) was remained associated with number of falls. CONCLUSIONS: Information about gait can be extracted from vision-based recordings of natural walking. In particular, the lateral margin of stability, a measure of lateral gait stability, is an important marker of short-term falls risk.

RESUMO

BACKGROUND: People with dementia experience a decline in language skills required to self-report pain; researchers thus recommend the use of nonverbal behaviors to assess pain. Although multiple instruments exist for assessing nonverbal pain behaviors, psychometric data are lacking for African American nursing home residents with dementia. AIMS AND DESIGN: The purpose of this methodological study was to describe the development and testing of the Pain Assessment Tool in Cognitively Impaired Elders (PATCIE) in African American and Caucasian nursing home residents with dementia. SETTINGS/PARTICIPANTS: The convenience sample included 56 African American and 69 Caucasian residents with dementia in multiple nursing homes from three states. The research staff completed the pain assessments when the nursing home staff transferred the residents. RESULTS/CONCLUSIONS: Initially, 15 nonverbal pain behaviors were evaluated. Based on the alpha scores and additional literature review, the 15 nonverbal pain behaviors were expanded to 28 behaviors. The PATCIE had a Cronbach's alpha of .73 during movement. Construct validity for the pain behaviors was demonstrated because higher scores were noted during movement, and scores before movement were significantly higher than those obtained after movement. For movement over time, there was a significant difference in the PATCIE score, regardless of ethnicity or time (p < .0001). There were no significant differences found between ethnic groups, either overall or in change over time between movements or between the categories of cognitive function. African Americans were more likely to display frowning, and Caucasians to display irritability. The PATCIE demonstrates preliminary reliability and validity in assessing pain in African American and Caucasian nursing home residents with dementia.

RESUMO

BACKGROUND: There is a need to more fully characterize financial capacity losses in the preclinical and prodromal stages of Alzheimer's disease (AD) and their pathological substrates. OBJECTIVES: To test the association between financial skills and cortical ß-amyloid deposition in aging and subjects at risk for AD. DESIGN: Cross-sectional analyses of data from the Alzheimer's Disease Neuroimaging Initiative (ADNI-3) study conducted across 50 plus sites in the US and Canada. SETTING: Multicenter biomarker study. PARTICIPANTS: 243 subjects (144 cognitively normal, 79 mild cognitive impairment [MCI], 20 mild AD). MEASUREMENTS: 18F-Florbetapir brain PET scans to measure global cortical ß-amyloid deposition (SUVr) and the Financial Capacity Instrument Short Form (FCI-SF) to evaluate an individual's financial skills in monetary calculation, financial concepts, checkbook/register usage, and bank statement usage. There are five sub scores and a total score (range of 0-74) with higher scores indicating better financial skill. RESULTS: FCI-SF total score was significantly worse in MCI [Cohen's d= 0.9 (95%CI: 0.6-1.2)] and AD subjects [Cohen's d=3.1(CI: 2.5-3.7)] compared to normals. Domain scores and completion times also showed significant difference. Across all subjects, higher cortical ß-amyloid SUVr was significantly associated with worse FCI-SF total score after co-varying for age, education, and cognitive score [Cohen's f2=0.751(CI: 0.5-1.1)]. In cognitively normal subjects, after covarying for age, gender, and education, higher ß -amyloid PET SUVr was associated with longer task completion time [Cohen's f2=0.198(CI: 0.06-0.37)]. CONCLUSION: Using a multicenter study sample, we document that financial capacity is impaired in the prodromal and mild stages of AD and that such impairments are, in part, associated with the extent of cortical ß-amyloid deposition. In normal aging, ß-amyloid deposition is associated with slowing of financial tasks. These data confirm and extend prior research highlighting the utility of financial capacity assessments in at risk samples.

RESUMO

BACKGROUND: Though the prevalence of dementia among hospitalized patients is increasing, there is limited population data in Europe about the use of life-support measures such as invasive mechanical ventilation in these patients. Our objective is to assess whether dementia influences the incidence, outcomes, and hospital resource use in elderly patients undergoing mechanical ventilation. METHODS: Using ICD-9-CM codes, all hospitalizations involving invasive mechanical ventilation in adults aged ≥ 65 years were identified in the Spanish national hospital discharge database covering the period 2000-2013. The cases identified were stratified into two cohorts (patients with or without dementia) in which main outcome measures were compared. The impact of dementia on in-hospital mortality and hospital resource use were assessed through multivariable models. Trends were assessed through joinpoint regression analysis and results expressed as average annual percentage change. RESULTS: Of the 259,623 cases identified, 5770 (2.2%) had been assigned codes for dementia. Cases with dementia were older, had a lower Charlson comorbidity score, and less frequently received prolonged mechanical ventilation or were assigned a surgical DRG. Circulatory disease was the most common main diagnosis in both cohorts. No significant impact of dementia was observed on in-hospital mortality (adjusted OR 1.04, [95% CI] 0.98, 1.09). In the cohort with dementia, the incidence of mechanical ventilation underwent an average annual increase over time of 5.39% (95% CI 4.0, 6.7) while this rate was 1.62% (95% CI 0.9, 2.4) in cases without dementia. However, unlike this cohort, mortality in cases with dementia did not significantly decline over time. Geometric mean hospital cost and stay were lower among cases with than without dementia (- 14% [95% CI - 12%, - 15%] and - 12% [95% CI, - 9%, - 14%], respectively), and these differences increased over time. CONCLUSION: This nationwide population-based study suggests no impact of dementia on in-hospital mortality in elderly patients undergoing invasive mechanical ventilation. However, dementia is significantly associated with shorter stay and hospital costs. Our data also identifies a recent marked increase in the use of this life-support measure in elderly patients with dementia and that this increase is much greater than that observed in elderly individuals without dementia.

RESUMO

Research on stress and disease has often afforded an important role to emotion, typically conceptualized in broad categories (e.g., negative emotions), viewed as playing a causal role (e.g., anger contributing to pathophysiology of cardiovascular disease), and measured using self-report inventories. In this article, I argue for the value of evaluating specific emotions, considering bidirectional causal influences, and assessing actual emotional responding when considering the role that emotions play in the stress-disease relationship. In terms of specificity, specific emotions (e.g., anger, sadness, and embarrassment) can be linked with particular health outcomes (e.g., cardiovascular disease and musculoskeletal disease). In terms of bidirectionality, the influences of emotions on disease as well as the influences of disease on emotional functioning can be considered. In terms of assessing actual emotional responding, emotions can be studied in vivo under controlled conditions that allow behavioral, physiological, and subjective responses to be measured during different kinds of emotional functioning (e.g., responding to emotional stimuli, interacting with relationship partners, and downregulating emotional responses). With these considerations in mind, I review early theories and empirical studies in psychosomatic medicine that considered the role of specific emotions and emotion-related behaviors. Studies from our laboratory are presented that illustrate a) differences in patterns of autonomic nervous system responding associated with specific emotions, b) relationships between specific emotions and particular health outcomes in the context of social relationships, c) age as a moderator of the relationship between specific emotions and well-being, d) bidirectional influences (emotions influencing disease and disease influencing emotional functioning), and e) impact of changes in emotional functioning in individuals with neurodegenerative diseases on the health of familial caregivers.

RESUMO

BACKGROUND AND OBJECTIVES: Osteoporosis and dementia are common and associated with a high healthcare burden. The aim of this paper was to assess the impact of dementia on treatment, morbidity and mortality in osteoporosis. METHOD: Data were collected on 502 prospective orthogeriatric admissions for fracture. Fisher's exact chi-square was used to compare treatment stratified by dementia status. RESULTS: Of the 502 patients, 281 (56%) had osteoporosis, 226 (45%) had dementia,  and 156 (31%) had dementia and osteoporosis diagnosed before they sustained fractures. Patients with dementia were more likely to have osteoporosis but less likely to be receiving treatment. Although there was a significant improvement in discharge versus admission rates of osteoporosis treatment, those with dementia were less likely to be treated with antiresorptive therapy (36%, compared with 59%, P <0.001) or combined therapy (32%, compared with 56%, P <0.001) and had double the 90-day mortality (17.3%, compared with 9.6%) and six times the 30-day mortality (6.4%, compared with 1.6%). DISCUSSION: Patients with dementia and osteoporosis have a higher risk of recurrent fractures and mortality. Prevention may be the key strategy.
