The German version of the Mini Suffering State Examination (MSSE) for people with advanced dementia living in nursing homes.

BACKGROUND: The Mini Suffering State Examination (MSSE) has been explicitly recommended to assess suffering in dementia patients. This study aimed to develop a German version of the MSSE and assess its psychometric properties involving people with advanced dementia (PAD) in a nursing home setting. METHODS: The MSSE was translated into German, and 95 primary nurses administered it cross-sectionally to 124 PAD in Zurich, Switzerland. The psychometric properties of the German MSSE version were calculated for this population. RESULTS: The mean age of the PAD was 83.3 years (SD = 9.1, range = 55-102 years), and 98 of them (79.0%) were women. The Kuder-Richardson Formula 20 coefficient for the entire scale (0.58), the eight items relating to objective health conditions (0.39), and the professional and family estimation of the patient's suffering (0.64) indicated low internal consistency. A confirmatory factor analysis indicated an unsatisfactory fit to a one-factor structure, with a comparative fit index and root mean square error of approximation of 0.71 and 0.08, respectively, and a Tucker-Lewis index of 0.64. The MSSE total score was significantly but moderately correlated with the total scores of the Symptom Management-End-of-Life with Dementia (SM-EOLD) scale (Pearson's correlation coefficient (r) = -0.44; p < 0.05), the physical suffering scores (r = 0.41; p < 0.05), and the psychological suffering scores (r = 0.55; p < 0.05). CONCLUSIONS: The German version of the MSSE questionnaire did not perform well in the nursing home setting involving PAD. The instrument had low internal consistency, doubtful validity, and could not discriminate between suffering and other distressing symptoms. We do not recommend its use in this population.

Aspects of oral health and dementia among Swiss nursing home residents.

BACKGROUND: Little empirical evidence of high levels of oral diseases of people in need of care and the impact of dementia is available. The resident assessment instrument minimum data set (RAI-MDS) is an evaluation tool for caregivers. OBJECTIVE: The aim of this study was to show oral health of nursing home residents through RAI-MDS 2.0 data as a function of the cognitive impairment. METHODS: A retrospective analysis of RAI-MDS (general, cognitive, oral health variables) of 357 long-term care facilities in Switzerland (data of 105,835 residents) was carried out. The final sample size was 7922 residents after applying the inclusion/exclusion criteria in four evaluation groups (no dementia, moderate, severe and incident dementia). RESULTS: As dementia developed and severity increased over time, subjects often had fewer or no teeth and did not wear removable dentures. Chewing problems increased over time regardless of the dementia severity. Oral complaints increased over time in subjects with severe dementia, which in turn led to low body mass index (BMI) values (<23 kg/m2) and was associated with an higher risk of mortality. CONCLUSION: This dataset provides an overview on dental aspects in patients with dementia in nursing homes. The accuracy of the assessment of a given dental situation by nursing staff is to be questioned. The results indicated an underdetection of oral illnesses by nurses.

Fact Box decision support tools reduce decisional conflict about antibiotics for pneumonia and artificial hydration in advanced dementia: a randomized controlled trail.

Background: fact Boxes are decision support tools that can inform about treatment effects. Objectives: to test whether Fact Box decision support tools impacted decisional conflict, knowledge and preferences about the use of antibiotics and artificial hydration in advanced dementia. Design: randomized controlled trial. Setting: Swiss-German region of Switzerland. Subjects: two hundred thirty-two participants (64 physicians, 100 relatives of dementia patients, 68 professional guardians) randomly allocated to intervention (N = 114) or control (N = 118). Intervention: two-page Fact Box decision support tools on antibiotics for pneumonia and artificial hydration in advanced dementia (at 1-month). Methods: participants were mailed questionnaires at baseline and one month later that asked questions about treatments based on hypothetical scenarios. The primary outcome was change in decisional conflict (DCS-D; range 0 < 100) about treatment decisions. Secondary outcomes included knowledge about treatments (range 0 < 7) and preferences to forego treatments. Results: participants were: mean age, 55.6 years; female, 62.8%. Relative to control participants, intervention participants experienced less decisional conflict about using antibiotics (unstandardized beta (b) = -8.35, 95% Confidence Interval (CI), -12.43, -4.28) and artificial hydration (b = -6.02, 95% CI, -9.84, -2.20) at 1-month compared to baseline. Intervention participants displayed greater knowledge about the use of antibiotics (b = 2.24, 95% CI, 1.79, 2.68) and artificial hydration (b = 3.01, 95% CI, 2.53, 3.49), and were significantly more likely to prefer to forego antibiotics (odds ratio, 2.29, 95% CI, 1.08, 4.84) but not artificial hydration. Conclusions: fact Box decision support tools reduced decisional conflict, increased knowledge and promoted preferences to forego antibiotics in advanced dementia among various decision-makers. Trial registration: FORSbase (12091).

Cognitive Change at the End of Life in Nursing Home Residents: Differential Trajectories of Terminal Decline.

BACKGROUND: Research on terminal decline has widely documented that cognitive performance steeply declines with nearing death. To date, it is unclear whether these changes are normative, based on pathologies associated with (preclinical) dementia, or both. OBJECTIVES: We analyzed heterogeneity in trajectories of terminal cognitive change in Swiss nursing home residents with the objective of examining whether terminal change is normative or whether one or multiple subgroup(s) with relative stability exist. METHODS: We performed a longitudinal analysis based on routine assessments with the Resident Assessment Instrument - Minimal Data Set in 341 nursing homes between 1998 and 2014. In sum, we used 143,052 observations from 30,054 residents (69% women, average age at death 87 years) in the last 3 years of life. We analyzed trajectories of the Cognitive Performance Scale (CPS) score with latent class growth curve models and examined sociodemographic factors (age at death, sex, marital status, prior living situation) as well as functional and mental health (Activities of Daily Living Index and Depression Rating Scale) and dementia diagnosis as correlates of group membership. RESULTS: We identified three distinct classes based on longitudinal trajectories of the CPS score. In the first group (transition from no to mild impairment, 27%), cognitive impairment increased with time to death (linear and quadratic), but remained at relatively mild levels at all times. The trajectories of the second group (transition from moderate to severe impairment, 43%) were characterized by linear and quadratic changes across time to death. The trajectories of the third group (severe impairment, 30%) were characterized by the lowest amount of linear increase across all groups and no quadratic increase indicating no accelerated change. Better functional health and absence of a dementia diagnosis predicted less impairment. Fewer depressive symptoms were associated with low as opposed to moderate or severe, but also severe versus moderate impairment. CONCLUSION: Our findings suggest that the majority of residents experience terminal change, with the exception of those at already high levels of impairment. Furthermore, late-life cognitive change is related to functional and mental health.

Physician and Surrogate Agreement with Assisted Dying and Continuous Deep Sedation in Advanced Dementia in Switzerland.

BACKGROUND: Assisted dying and continuous deep sedation (CDS) are controversial practices. Little is known about the perceptions of physicians and surrogates about these practices for patients with advanced dementia. OBJECTIVES: To describe and compare physician and surrogate agreement with the use of assisted dying and CDS in advanced dementia. DESIGN, SETTING, SUBJECTS: Physicians (n = 64) and surrogates (n = 168) of persons with advanced dementia were recruited as part of a randomized controlled trial in Switzerland that tested decision support tools in this population. METHODS: At baseline, the participants were asked about their agreement with assisted dying and CDS in advanced dementia using the following response options: "completely agree," "somewhat agree," "somewhat disagree," "completely disagree," and "do not know." Multivariable logistic regressions compared the likelihood that surrogates versus physicians would completely or somewhat agree (vs. completely or somewhat disagree) with these practices. RESULTS: The physicians and surrogates, respectively, had a mean age (SD) of 50.6 years (9.9) and 57.4 years (14.6); 46.9% (n = 30/64) and 68.9% (n = 115/167) were women. A total of 20.3% (n = 13/64) of the physicians and 47.0% (n = 79/168) of the surrogates agreed with assisted dying in advanced dementia. Surrogates were significantly more likely to agree with this practice than physicians (adjusted odds ratio, 3.87; 95% CI: 1.94, 7.69). With regard to CDS, 51.6% (n = 33/64) of the physicians and 41.9% (n = 70/169) of the surrogates agreed with this practice, which did not differ significantly between the groups. CONCLUSIONS: The surrogates were more agreeable to considering assisted dying in the setting of advanced dementia than the physicians, and about half of the participants in both groups reported CDS to be an appropriate option for this population.

Urinary incontinence and its association with functional physical and cognitive health among female nursing home residents in Switzerland.

BACKGROUND: Specific knowledge of urinary incontinence (UI) and its interrelation with physical and cognitive health is essential to working towards prevention of UI and to improving quality of treatment and care. The purpose of this study was to determine the association between UI and the activities of daily living (ADL) hierarchy scale, the cognitive performance scale (CPS) and comorbid conditions. METHODS: The cross-sectional retrospective analysis of 357 nursing homes in Switzerland was based on data of the Minimum Data Set of the Resident Assessment Instrument 2.0 (RAI-MDS). The analysis examined the effect of ADL hierarchy scale, CPS, joint motion and comorbidities on UI. Women ≥65 years were included (n = 44'811; January 2005 to September 2014) at the time of admission to a nursing home. Statistical analysis was done by means of descriptive statistics and logistic regression analysis. RESULTS: The prevalence of UI was 54.7%, the mean ADL hierarchy scale (± SD) 2.42 ± 3.26 (range = 0-6), the mean CPS 1.95 ± 1.67 (range = 0-6). There was a gradual increase in the odds ratio (OR) for UI depending on the ADL hierarchy scale, from the hierarchy scales of "supervised" to "total dependence" of 1.43 - 30.25. For CPS, the OR for UI from "borderline intact" to "very severe impairment" was 1.35 - 5.99. Considering the interaction between ADL and CPS, all ADL hierarchies remained significantly associated with UI, however for CPS this was the case only in the lower hierarchies. Of the 11 examined comorbid conditions, only diabetes mellitus (OR 1.19), dementia (OR 1.01) and arthrosis/arthritis (OR 1.53) were significantly associated with UI. CONCLUSION: The study indicated that impairment in ADL performance is strongly associated with UI, more than CPS performance and comorbidities. Physical more than cognitive training in order to improve or at least stabilize ADL performance could be a way to prevent or reduce the process of developing UI.

The last phase of life with dementia in Swiss nursing homes: the study protocol of the longitudinal and prospective ZULIDAD study.

BACKGROUND: The proportion of older people with advanced dementia who will die in nursing homes is constantly growing. However, little is known about the dying phase, the type of symptoms, the management of symptoms and the quality of life and dying in people with advanced dementia. The ZULIDAD (Zurich Life and Death with Advanced Dementia) study aims at extending the current scientific knowledge by providing first data from Switzerland. METHODS: The ZULIDAD study employs a prospective design to study nursing home residents with advanced dementia for three years or until their death in eleven nursing homes in Zurich. Observational data from quarterly questionnaires for relatives and primary nurses is combined with data from the Resident Assessment Instrument - Minimum Data Set (RAI-MDS). Special focus is put on 1) the cross-sectional analysis of baseline and post-mortem data regarding quality of life and quality of dying and how the perceptions of these measures differ between relatives and primary nurses, 2) the longitudinal analyses of established health outcome measures (e.g., EOLD, MSSE, BISAD, QUALID) in order to understand their trajectories and 3) international comparisons of cross-sectional and longitudinal data. DISCUSSION: The ZULIDAD study is one of the few existing prospective studies on end-of-life care in dementia and it is the first prospective study to describe the situation in Switzerland. Its multi-perspective approach allows a comprehensive approximation to central health outcome measures at the end of life such as pain, suffering or quality of life. Providing insights into the current provision of care, it can serve as a basis for improving dementia end-of-life care in Switzerland and internationally.

Childhood maternal care is associated with DNA methylation of the genes for brain-derived neurotrophic factor (BDNF) and oxytocin receptor (OXTR) in peripheral blood cells in adult men and women.

In adults, reporting low and high maternal care in childhood, we compared DNA methylation in two stress-associated genes (two target sequences in the oxytocin receptor gene, OXTR; one in the brain-derived neurotrophic factor gene, BDNF) in peripheral whole blood, in a cross-sectional study (University of Basel, Switzerland) during 2007-2008. We recruited 89 participants scoring < 27 (n = 47, 36 women) or > 33 (n = 42, 35 women) on the maternal care subscale of the Parental Bonding Instrument (PBI) at a previous assessment of a larger group (N = 709, range PBI maternal care = 0-36, age range = 19-66 years; median 24 years). 85 participants gave blood for DNA methylation analyses (Sequenom(R) EpiTYPER, San Diego, CA) and cell count (Sysmex PocH-100i™, Kobe, Japan). Mixed model statistical analysis showed greater DNA methylation in the low versus high maternal care group, in the BDNF target sequence [Likelihood-Ratio (1) = 4.47; p = 0.035] and in one OXTR target sequence Likelihood-Ratio (1) = 4.33; p = 0.037], but not the second OXTR target sequence [Likelihood-Ratio (1) < 0.001; p = 0.995). Mediation analyses indicated that differential blood cell count did not explain associations between low maternal care and BDNF (estimate = -0.005, 95% CI = -0.025 to 0.015; p = 0.626) or OXTR DNA methylation (estimate = -0.015, 95% CI = -0.038 to 0.008; p = 0.192). Hence, low maternal care in childhood was associated with greater DNA methylation in an OXTR and a BDNF target sequence in blood cells in adulthood. Although the study has limitations (cross-sectional, a wide age range, only three target sequences in two genes studied, small effects, uncertain relevance of changes in blood cells to gene methylation in brain), the findings may indicate components of the epiphenotype from early life stress.

Effects of simultaneously performed cognitive and physical training in older adults.

BACKGROUND: While many studies confirm the positive effect of cognitive and physical training on cognitive performance of older adults, only little is known about the effects of simultaneously performed cognitive and physical training. In the current study, older adults simultaneously performed a verbal working memory and a cardiovascular training to improve cognitive and motor-cognitive dual task performance. Twenty training sessions of 30 minutes each were conducted over a period of ten weeks, with a test session before, in the middle, and after the training. Training gains were tested in measures of selective attention, paired-associates learning, executive control, reasoning, memory span, information processing speed, and motor-cognitive dual task performance in the form of walking and simultaneously performing a working memory task. RESULTS: Sixty-three participants with a mean age of 71.8 ± 4.9 years (range 65 to 84) either performed the simultaneous training (N = 21), performed a single working memory training (N = 16), or attended no training at all (N = 26). The results indicate similar training progress and larger improvements in the executive control task for both training groups when compared to the passive control group. In addition, the simultaneous training resulted in larger improvements compared to the single cognitive training in the paired-associates task and was able to reduce the step-to-step variability during the motor-cognitive dual task when compared to the single cognitive training and the passive control group. CONCLUSIONS: The simultaneous training of cognitive and physical abilities presents a promising training concept to improve cognitive and motor-cognitive dual task performance, offering greater potential on daily life functioning, which usually involves the recruitment of multiple abilities and resources rather than a single one.

Multicomponent physical exercise with simultaneous cognitive training to enhance dual-task walking of older adults: a secondary analysis of a 6-month randomized controlled trial with 1-year follow-up.

BACKGROUND: About one-third of people older than 65 years fall at least once a year. Physical exercise has been previously demonstrated to improve gait, enhance physical fitness, and prevent falls. Nonetheless, the addition of cognitive training components may potentially increase these effects, since cognitive impairment is related to gait irregularities and fall risk. We hypothesized that simultaneous cognitive-physical training would lead to greater improvements in dual-task (DT) gait compared to exclusive physical training. METHODS: Elderly persons older than 70 years and without cognitive impairment were randomly assigned to the following groups: 1) virtual reality video game dancing (DANCE), 2) treadmill walking with simultaneous verbal memory training (MEMORY), or 3) treadmill walking (PHYS). Each program was complemented with strength and balance exercises. Two 1-hour training sessions per week over 6 months were applied. Gait variables, functional fitness (Short Physical Performance Battery, 6-minute walk), and fall frequencies were assessed at baseline, after 3 months and 6 months, and at 1-year follow-up. Multiple regression analyses with planned comparisons were carried out. RESULTS: Eighty-nine participants were randomized to three groups initially; 71 completed the training and 47 were available at 1-year follow-up. DANCE/MEMORY showed a significant advantage compared to PHYS in DT costs of step time variability at fast walking (P=0.044). Training-specific gait adaptations were found on comparing DANCE and MEMORY: DANCE reduced step time at fast walking (P=0.007) and MEMORY reduced gait variability in DT and DT costs at preferred walking speed (both trend P=0.062). Global linear time effects showed improved gait (P<0.05), functional fitness (P<0.05), and reduced fall frequency (-77%, P<0.001). Only single-task fast walking, gait variability at preferred walking speed, and Short Physical Performance Battery were reduced at follow-up (all P<0.05 or trend). CONCLUSION: Long-term multicomponent cognitive-physical and exclusive physical training programs demonstrated similar potential to counteract age-related decline in physical functioning.

Does multicomponent physical exercise with simultaneous cognitive training boost cognitive performance in older adults? A 6-month randomized controlled trial with a 1-year follow-up.

BACKGROUND: Cognitive impairment is a health problem that concerns almost every second elderly person. Physical and cognitive training have differential positive effects on cognition, but have been rarely applied in combination. This study evaluates synergistic effects of multicomponent physical exercise complemented with novel simultaneous cognitive training on cognition in older adults. We hypothesized that simultaneous cognitive-physical components would add training specific cognitive benefits compared to exclusively physical training. METHODS: Seniors, older than 70 years, without cognitive impairment, were randomly assigned to either: 1) virtual reality video game dancing (DANCE), 2) treadmill walking with simultaneous verbal memory training (MEMORY), or 3) treadmill walking (PHYS). Each program was complemented with strength and balance exercises. Two 1-hour training sessions per week over 6 months were applied. Cognitive performance was assessed at baseline, after 3 and 6 months, and at 1-year follow-up. Multiple regression analyses with planned comparisons were calculated. RESULTS: Eighty-nine participants were randomized to the three groups initially, 71 completed the training, while 47 were available at 1-year follow-up. Advantages of the simultaneous cognitive-physical programs were found in two dimensions of executive function. "Shifting attention" showed a time×intervention interaction in favor of DANCE/MEMORY versus PHYS (F[2, 68] =1.95, trend P=0.075, r=0.17); and "working memory" showed a time×intervention interaction in favor of DANCE versus MEMORY (F[1, 136] =2.71, trend P=0.051, R (2)=0.006). Performance improvements in executive functions, long-term visual memory (episodic memory), and processing speed were maintained at follow-up in all groups. CONCLUSION: Particular executive functions benefit from simultaneous cognitive-physical training compared to exclusively physical multicomponent training. Cognitive-physical training programs may counteract widespread cognitive impairments in the elderly.

The drive-wise project: driving simulator training increases real driving performance in healthy older drivers.

BACKGROUND: Age-related cognitive decline is often associated with unsafe driving behavior. We hypothesized that 10 active training sessions in a driving simulator increase cognitive and on-road driving performance. In addition, driving simulator training should outperform cognitive training. METHODS: Ninety-one healthy active drivers (62-87 years) were randomly assigned to one of three groups: (1) a driving simulator training group, (2) an attention training group (vigilance and selective attention), or (3) a control group. The main outcome variables were on-road driving and cognitive performance. Seventy-seven participants (85%) completed the training and were included in the analyses. Training gains were analyzed using a multiple regression analysis with planned orthogonal comparisons. RESULTS: The driving simulator-training group showed an improvement in on-road driving performance compared to the attention-training group. In addition, both training groups increased cognitive performance compared to the control group. CONCLUSION: Driving simulator training offers the potential to enhance driving skills in older drivers. Compared to the attention training, the simulator training seems to be a more powerful program for increasing older drivers' safety on the road.

Simultaneously measuring gait and cognitive performance in cognitively healthy and cognitively impaired older adults: the Basel motor-cognition dual-task paradigm.

OBJECTIVES: To investigate dual-task performance of gait and cognition in cognitively healthy and cognitively impaired older adults using a motor-cognition dual-task paradigm. DESIGN: Cross-sectional retrospective study. SETTING: The Basel Memory Clinic and the Basel Study on the Elderly (Project BASEL). PARTICIPANTS: Seven hundred eleven older adults (mean age 77.2±6.2, 350 (49.2%) female and 361 (50.8%) male). MEASUREMENTS: Gait velocity and cognitive task performance using a working memory (counting backward from 50 by 2s) and a semantic memory (enumerating animal names) task were measured during single- and dual-task conditions. Gait was assessed using the GAITRite electronic walkway system. Cognitive impairment was defined as a score less than 25 on the Mini-Mental State Examination. RESULTS: During dual tasks, participants reduced gait velocity (P<.001) and calculated fewer numbers (P=.03) but did not enumerate fewer animals and did not make more errors or repetitions (P>.10). Cognitively impaired individuals had lower baseline gait velocity and a greater reduction in gait velocity but not cognitive performance during dual tasks than cognitively healthy participants (P<.01). CONCLUSION: Gait velocity was lower during both dual tasks, whereas decrease in cognitive performance depended on the cognitive ability needed in the dual-task condition. Cognitively impaired individuals generally have poorer baseline performance and greater dual task-related gait velocity reduction than those who are cognitively healthy. Future research should include different conditions for gait to determine adaptive potentials of older adults.
