Executive and memory dysfunction related to binge drinking in stroke survivors during a 9-year follow-up.

Background: Ischemic stroke and heavy alcohol consumption are both known risk factors for cognitive impairment. The issue gains importance because the prevalence of stroke and binge drinking have both increased among working-aged adults. Alarmingly, a recent cross-sectional study suggests the additive negative effects of binge drinking and comorbid brain disease on cognition. However, the long-term cognitive prognosis of the additive effects of stroke and binge drinking on adults remains unknown. Methods: In this prospective, two-center cohort study, we recruited consecutive 18-65-year-old patients with first-ever ischemic stroke along with demographically matched stroke-free controls. Patients participated in neuropsychological assessment at 6 months, 2 years, and 9 years after stroke, and in neurological assessment at acute care and at 9-year follow-up. Controls participated in a similar follow-up procedure. We examined the association between binge drinking, follow-up time, and long-term cognitive outcomes using repeated-measures analysis of variance. Results: We included 85 patients who had had their first-ever and only ischemic stroke (mean age 53 years at the incident stroke). Patients were divided into binge-drinking (n = 22) and non-binge-drinking groups (n = 63) based on the shortened version of the Alcohol Use Disorders Identification Test. Follow-up data in healthy controls (n = 31) was used to normalize the patients' test scores for effects of age, sex, and education. We compared cognitive changes between binge-drinking and non-binge-drinking patients over a 9-year follow-up. Non-binge-drinking patients outperformed binge-drinking patients across all follow-up points on most of the executive function tests and in one memory test: binge drinking had a significant main effect both on executive function (the phonemic fluency task, p = 0.002; the Trail Making Test, p = 0.013) and memory (the list learning task, p = 0.002). Conclusion: Binge drinking was associated with executive and memory dysfunction at three time points over a decade after a first-ever ischemic stroke. Subdiagnostic binge drinking might increase the adverse effects of a first-ever ischemic stroke on executive function and memory, evident over a decade poststroke.

The ecosystem of human capital in care homes.

Introduction: This qualitative study addresses the essential yet often overlooked experiences of knowledge transfer within care homes (CH). Conducted in a Slovenian CH in 2020 and 2023, participants, including CH management, staff, and residents with their relatives, shared perceptions of knowledge transfer at various levels. The study aims to explore barriers and facilitators for knowledge transfer crucial for creating new knowledge, services, and enhancing care quality for older individuals. Methods: Structured focus group interviews were conducted, and data were collected within the CH. The participants' insights into knowledge transfer were probed, covering various dimensions such as between individuals, groups, organizations, and the community. Transcriptions of recorded interviews were analyzed using content analysis. Results: Knowledge transfer within the CH was facilitated through continuous training, diverse communication channels, and mentoring. Collaboration with relatives improved understanding of resident preferences, habits, and overall enhanced the quality of care. This collaborative effort allowed mutual learning and knowledge transfer from the CH to the broader community. Despite potential benefits, there is an underutilization of information and communication technology, e-care, and untapped potential for partnerships, partly due to the scarcity of care. Barriers were identified in the form of stereotypical attitudes towards aging and care, further reinforced by negative news coverage on older people's care. Conclusion: The multidimensional nature of knowledge in CH centers on resident well-being, emphasizing three key aspects of knowledge transfer: between staff and residents, staff and residents' families, and between the CH and the community. In the context of age management, creating opportunities for knowledge transfer is crucial, emphasizing a transition from traditional institutional care to an approach prioritizing knowledge about quality care. and involving experts from experiences in care process.

Memory decline in young stroke survivors during a 9-year follow-up: A cohort study.

Introduction: A decade after stroke, young stroke survivors continue to suffer from cognitive impairment. However, it is not known whether this long-term cognitive outcome is caused in part by further cognitive decline or solely by incomplete recovery from the acute effects of ischemic stroke. We studied changes in three cognitive domains over a 9-year follow-up period after first-ever and only ischemic stroke. Patients and methods: In this prospective, two-center cohort study, we recruited consecutive 18-65 year-old patients with acute stroke between 2007 and 2009, along with demographically matched stroke-free controls. We performed comprehensive neuropsychological assessments at 3 months, 2, and 9 years after stroke, and we also performed neurological examinations at the time of inclusion and at the 9-year follow-up. We assessed the associations among stroke, follow-up time and long-term cognitive outcomes using repeated-measures analysis of variance. Results: The subjects comprised 85 patients who had had their first-ever and only ischemic stroke (mean age 53 years at inclusion), along with 31 stroke-free demographic controls. We compared the cognitive changes in patients to those in controls over a 9-year follow-up. After initial recovery between 3 months and 2 years after stroke, patients showed a decline in memory between 2 and 9 years after stroke compared to controls within the same time interval (immediate recall p < 0.001; delayed recall p < 0.001; list learning p < 0.001). Other than memory, we found no difference in cognitive changes between poststroke patients and controls. Discussion: Our main finding was memory decline over a decade in young first-ever stroke patients with no further stroke or neurodegenerative disease. Our study extends the previous results of further memory decline in elderly stroke survivors to young stroke survivors. Conclusion: Young stroke survivors might be at risk of memory decline over the decade following the stroke.

Associations of neuroticism with falls in older adults: do psychological factors mediate the association?

OBJECTIVES: Neuroticism predicts falls in older people. In addition, concern about falling and depressive symptoms are associated with fall risk. This study examined whether concern about falling and depressive symptoms mediate the association between neuroticism and falls. METHOD: Cross-sectional data on 314 community-dwelling people aged 70-85 years were utilized. Neuroticism was assessed with a short modified form of the Eysenck Personality Inventory. Indoor and outdoor falls during the past year were self-reported. Concern about falling was assessed with the Falls Efficacy Scale-International and depressive symptoms with the Geriatric Depression Scale-15. Path modeling was used to examine the associations between variables. RESULTS: Mediating pathways linking neuroticism and falls were found: neuroticism was positively associated with concern about falling, which was subsequently linked to indoor falls (indirect effect ß = 0.34, p = 0.002) and recurrent outdoor falls (ß = 0.19, p = 0.045). Moreover, a pathway from neuroticism to indoor falls through depressive symptoms was also found (ß = 0.21, p = 0.054). In other words, higher neuroticism was associated with higher concern about falling and depressive symptoms, both of which were linked to falls. The associations were independent of age, sex, use of psychotropic, chronic diseases, persistent pain, physical performance, physical activity, and executive functioning that are known risk factors for falls. DISCUSSION: The results indicate that concern about falling and depressive symptoms mediate the association between neuroticism and falling. Longitudinal studies are needed to confirm the causality of the findings and to examine the potential to reduce falls by targeting concern about falling and depressive symptoms among older adults higher in neuroticism.

Effects of Physical and Cognitive Training on Falls and Concern About Falling in Older Adults: Results From a Randomized Controlled Trial.

BACKGROUND: The aim of this study is to investigate whether combined cognitive and physical training provides additional benefits to fall prevention when compared with physical training (PT) alone in older adults. METHODS: This is a prespecified secondary analysis of a single-blind, randomized controlled trial involving community-dwelling men and women aged 70-85 years who did not meet the physical activity guidelines. The participants were randomized into combined physical and cognitive training (PTCT, n = 155) and PT (n = 159) groups. PT included supervised and home-based physical exercises following the physical activity recommendations. PTCT included PT and computer-based cognitive training. The outcome was the rate of falls over the 12-month intervention (PTCT, n = 151 and PT, n = 155) and 12-month postintervention follow-up (PTCT, n = 143 and PT, n = 148). Falls were ascertained from monthly diaries. Exploratory outcomes included the rate of injurious falls, faller/recurrent faller/fall-related fracture status, and concern about falling. RESULTS: Estimated incidence rates of falls per person-year were 0.8 (95% confidence interval [CI] 0.7-1.1) in the PTCT and 1.1 (95% CI 0.9-1.3) in the PT during the intervention and 0.8 (95% CI 0.7-1.0) versus 1.0 (95% CI 0.8-1.1), respectively, during the postintervention follow-up. There was no significant difference in the rate of falls during the intervention (incidence rate ratio [IRR] = 0.78; 95% CI 0.56-1.10, p = .152) or in the follow-up (IRR = 0.83; 95% CI 0.59-1.15, p = .263). No significant between-group differences were observed in any exploratory outcomes. CONCLUSION: A yearlong PTCT intervention did not result in a significantly lower rate of falls or concern about falling than PT alone in older community-dwelling adults.

Clinical aspects of heat-labile and heat-stable toxin-producing enterotoxigenic Escherichia coli: A prospective study among Finnish travellers.

BACKGROUND: Enterotoxigenic Escherichia coli (ETEC) is a major pathogen causing travellers' diarrhoea (TD) among visitors to low- and middle-income countries (LMIC). Scant data are available on rates of travel-acquired ETEC producing heat-labile (LT) and/or heat-stable (ST) toxin or its subtypes, STh (human) and STp (porcine) in various geographic regions, and on clinical pictures associated with each toxin. METHODS: Using qPCR, we analysed LT, STh, and STp in stools positive for ETEC in a prospective study among 103 Finnish travellers visiting LMIC. They filled in questionnaires and provided stool samples before and after travel. We scrutinized geographic distribution of LT, STh, and STp ETEC findings, and association between these different ETEC subtypes and moderate/severe TD. RESULTS: Among the 103 stool samples positive for ETEC toxins, the rate for LT was 76%, for STh 26%, and STp 41%. The rate for LT-only was 44%, for STh-only 6%, STp-only 16%, LT + STh 10%, LT + STp 15%, STh + STp 3%, and LT + STh + STp 8%. Findings varied by destination; the rates of LT, STh, and STp were 79%, 21%, and 57%, respectively, in Southern Asia (n = 14); 85%, 10%, and 20% in South-eastern Asia (n = 20); 84%, 13%, and 29% in Eastern Africa (n = 31); and 56%, 50%, and 63% in Western Africa (n = 32), respectively. Of travellers positive for LT, STh, and STp, 83%, 100%, and 88%, encountered TD; 35%, 55%, and 41% reported moderate/severe TD. STh was associated with moderate/severe TD. CONCLUSIONS: Toxin findings varied by destination; multiple toxins were commonly detected. Moderate/severe TD was reported most frequently by subjects with STh-ETEC.

Executive Dysfunction Related to Binge Drinking in Ischemic Stroke.

BACKGROUND: Recent evidence has shown that cognitive dysfunction is associated with a history of binge drinking in adolescents who do not have an alcohol use disorder. Most previous studies with adults, however, have failed to show a link between cognitive dysfunction and subdiagnostic binge drinking, nor have any studies investigated the additive cognitive effect of binge drinking to ischemic stroke. OBJECTIVE: To examine whether a pattern of cognitive dysfunction, especially executive and memory dysfunction, in patients with a first-ever ischemic stroke is associated with a history of subdiagnostic binge drinking. METHODS: We studied 206 first-ever ischemic stroke patients (18-65 years) and 50 healthy, demographically comparable adults-both groups with no alcohol use disorder. After exclusion by matching, 189 patients and 39 healthy participants were included in our study (228 participants). The binge-drinking group included 76 participants; the non-binge-drinking group included 152. A multivariate analysis of covariance was used to compare nine cognitive functions between the two groups, with age, education, and stroke severity used as covariates. RESULTS: Binge drinking had a significant negative effect on executive functions (P<0.001). The non-binge-drinking group outperformed the binge-drinking group on the Stroop Test (P=0.001), Trail Making Test (P=0.002), and a phonemic fluency test (P=0.005). The Binge×Stroke Severity interaction (P=0.037) indicated that a history of binge drinking increased the negative effect of stroke on executive functions. CONCLUSIONS: Subdiagnostic binge drinking may exacerbate the adverse effects of ischemic stroke on executive dysfunction.

Effects of an individually targeted multicomponent counseling and home-based rehabilitation program on physical activity and mobility in community-dwelling older people after discharge from hospital: a randomized controlled trial.

OBJECTIVES: The aim of this study is to evaluate the effects of multicomponent rehabilitation on physical activity, sedentary behavior, and mobility in older people recently discharged from hospital. DESIGN: Randomized controlled trial. SETTING: Home and community. PARTICIPANTS: Community-dwelling people aged ⩾60 years recovering from a lower limb or back musculoskeletal injury, surgery, or disorder were recruited from local health center hospitals and randomly assigned into an intervention (n = 59) or a control (standard care, n = 58) group. INTERVENTION: The six-month intervention consisted of a motivational interview, goal attainment process, guidance for safe walking, a progressive home exercise program, physical activity counseling, and standard care. MEASUREMENTS: Physical activity and sedentary time were assessed using an accelerometer and a single question. Mobility was evaluated with the Short Physical Performance Battery, self-reported use of a walking aid, and ability to negotiate stairs and walk outdoors. Intervention effects were analyzed with generalized estimating equations. RESULTS: Daily physical activity was 127 ± 78 minutes/day and 121 ± 70 at baseline and 167 ± 81 and 164 ± 72 at six months in the intervention and control group, respectively; mean difference of 3.4 minutes (95% confidence interval (CI) = -20.3 to 27.1). In addition, no significant between-group differences were shown in physical performance. CONCLUSION: The rehabilitation program was not superior to standard care for increasing physical activity or improving physical performance. Mobility-limited older people who had recently returned home from hospital would have needed a longer and more frequently monitored comprehensive geriatric intervention.

Domain-Specific Cognitive Recovery after First-Ever Stroke: A 2-Year Follow-Up.

OBJECTIVES: The aim of this work was to study the change in different cognitive domains after stroke during a 2-year follow-up. METHOD: We evaluated both neuropsychologically and neurologically a consecutive cohort of working-age patients with a first-ever stroke at baseline (within the first weeks), 6 months, and 2 years after stroke-onset. A total of 153 patients participated in all examinations and were compared to 50 healthy controls. RESULTS: Forty-nine percent of the patients were cognitively impaired at baseline, 41% at 6 months, and 39% at 2-year follow-up. We analyzed seven cognitive domains (impairment rates at baseline and 2-year follow-up): psychomotor speed (34%; 23%), executive functions (27%; 17%), visual memory (21%; 4%), visuospatial function (20%; 14%), verbal memory (18%; 12%), basic language processing (baseline 11%; 6 months 5%), and reasoning (2 years 14%). The patients who were cognitively impaired at baseline improved more within 6 months, than either the controls or cognitively intact patients in all cognitive domains (all p<.05). Later on, between 6 months and 2 years, the domain-specific change scores did not differ between patients who were cognitively intact and impaired at 6 months. Also, the cognitive status (intact or impaired) remained the same in 90% of patients between 6-month and 2-year follow-ups. At 2 years, half of the patients, who were categorized cognitively impaired, were rated as well-recovered according to neurological evaluation. CONCLUSIONS: Most of the cognitive improvement took place within 6 months. Long-lasting cognitive impairment was common even after good neurological recovery. An early neuropsychological examination is essential in evaluating cognitive dysfunction and need for rehabilitation. (JINS, 2018, 24, 117-127).

Physical Activity After a Hip Fracture: Effect of a Multicomponent Home-Based Rehabilitation Program-A Secondary Analysis of a Randomized Controlled Trial.

OBJECTIVES: To investigate the effect of a yearlong multicomponent rehabilitation program on the level of physical activity (PA) and the maintenance of the level of PA over 1-year follow-up among older people recovering from a recent hip fracture. DESIGN: Secondary analysis of a randomized, controlled, parallel-group trial. SETTING: Home-based rehabilitation; measurements in university laboratory. PARTICIPANTS: Community-dwelling people (N=81) aged ≥60 years recovering from a hip fracture. Participants were randomly assigned to an intervention (n=40) or a control (n=41) group, on average, 42±23 days after discharge from the hospital. INTERVENTION: A yearlong intervention included evaluation and modification of environmental hazards, guidance for safe walking, nonpharmacologic pain management, a progressive home exercise program, PA counseling, and standard care. MAIN OUTCOME MEASURES: The outcome was the level of PA, which was assessed with the questionnaire (a modified Grimby scale) at baseline, and 3, 6, 12, and 24 months after baseline. Three PA categories were defined: inactivity, light PA, and moderate to heavy PA. Physical function was assessed using the Short Physical Performance Battery (SPPB) at baseline. The effects of the intervention were analyzed with generalized estimating equations. RESULTS: In the intervention group, a significant increase was observed in the level of PA after the intervention (interaction P=.005) and after 1-year follow-up (P=.021) compared with the standard care only. The benefit was particularly evident among the participants with a baseline SPPB score of ≥7 (interaction P<.001). CONCLUSIONS: The 12-month individualized multicomponent rehabilitation program increased PA among older patients with hip fracture. The increase was found to be maintained at the 1-year follow-up.

Executive Impairment Is Associated with Impaired Memory Performance in Working-Aged Stroke Patients.

OBJECTIVES: Executive dysfunction is associated with impaired memory performance, but controversies remain about which aspects of memory are involved and how general intelligence influences these connections. We aimed to clarify these connections in stroke patients by comparing various memory measures in patients with and without executive impairment. METHODS: Our consecutive cohort included patients with a first-ever ischemic stroke. Neuropsychological assessments were completed 6 months and 2 years after stroke. We classified patients as executively impaired, when at least two of five executive measures were defective at 6 months. At both 6 months and 2 years, we compared list learning of unrelated words, story recall, and recall of geometric figures in patients with and without executive impairment, while controlling for general intelligence. RESULTS: Patients with executive impairment (n=66; 37%) performed worse in list learning (p=.001; partial η2=.058) and immediate recall of a logical passage (p=.010; partial η2=.037) 6 months after stroke compared to executively intact patients (n=113). At the end of the 2-year follow-up period, the patients who were executively impaired at 6 months (n=53; 37%) still performed worse than executively intact patients (n=92) in list learning (p<.001; partial η2=.096), and additionally in delayed recall of the list (p=.006; partial η2=.052) and immediate recall of geometric figures (p=.007; partial η2=.050). CONCLUSIONS: In our working-aged stroke patients, executive impairment was common. Executive impairment was associated with memory tasks that provided less inherent structure and required the use of active memory strategies. Clinicians should remember this role of executive dysfunction when interpreting memory performance.

Use of Stroke-Related Income Supplements and Predictors of Use in a Working-Aged Finnish Ischemic Stroke Cohort.

BACKGROUND: Compared with the direct costs, the indirect costs of stroke may be larger contributors to the socioeconomic burden of stroke, and the need to better understand the indirect costs of stroke is well established. We investigated the indirect costs of stroke according to a novel outcome, the use of stroke-related income supplements, in a Finnish cohort of working-aged patients. METHODS: Consecutive patients (n = 230) who experienced a first-ever ischemic stroke were recruited. Demographic, clinical, and cognitive function data (which were measured using clinical neuropsychological assessments) were collected at baseline and at 6-month and 2-year follow-ups. Data on the use of income supplements within the first 3 years of the stroke were retrieved from national insurance registry files and used to construct survival models. RESULTS: Stroke patients used a mean of 11 months of stroke-related income supplements; this use was associated with atrial fibrillation, cognitive impairment, prestroke income supplement use, higher National Institutes of Health Stroke Scale scores, lower Barthel Index scores, and increased lesion sizes. In multivariate survival models, atrial fibrillation and cognitive impairment were the factors most strongly associated with the use of stroke-related income supplements. CONCLUSIONS: Using stroke-related income supplement data to quantify poststroke productivity losses allowed a working-aged cohort to be investigated without inclusion restrictions based on occupational status or other factors; the use of these data as an outcome emphasized the well-known detrimental effects of atrial fibrillation and cognitive impairment on stroke outcome. The results support stroke-related income supplement use as a complementary outcome for understanding stroke-related productivity losses.

The cognitive burden of stroke emerges even with an intact NIH Stroke Scale Score: a cohort study.

BACKGROUND: We aim to facilitate recognition of the cognitive burden of stroke by describing the parallels between cognitive deficits and the National Institutes of Health Stroke Scale (NIHSS), a widely used measure of stroke severity. METHODS: A consecutive cohort of 223 working-age patients with an acute first-ever ischaemic stroke was assessed neuropsychologically within the first weeks after stroke and at a 6-months follow-up visit and compared with 50 healthy demographic controls. The NIHSS was administered at the time of hospital admittance and upon discharge from the acute care unit. The associations between total NIHSS scores and domain-specific cognitive deficits were analysed correlatively and with a binary logistic regression. RESULTS: Of the NIHSS measurements (admittance median=3, range 0-24; discharge median=1, range 0-13), the total score at the time of discharge had systematically stronger correlations with cognitive impairment. Adjusted for demographics, the NIHSS discharge score stably predicted every cognitive deficit with ORs ranging from 1.4 (95% CI 1.2 to 1.6) for episodic memory to 1.9 (95% CI 1.5 to 2.3) for motor skills. The specificities of the models ranged from 89.5-97.7%, but the sensitivities were as low as 11.6-47.9%. Cognitive deficits were found in 41% of patients with intact NIHSS scores and in all patients with NIHSS scores ≥4, a finding that could not be accounted for by confounding factors. CONCLUSIONS: Cognitive deficits were common even in patients with the lowest NIHSS scores. Thus, low NIHSS scores are not effective indicators of good cognitive outcomes after stroke.

The severity of cognitive deficits predicts return to work after a first-ever ischaemic stroke.

BACKGROUND: The inability of stroke patients to return to work contributes disproportionately to the socioeconomic impact of stroke and is best predicted by the severity of stroke. However, the role of cognitive deficits in stroke severity has not been scrutinised. We studied whether the initial cognitive severity of stroke, compared with other influential factors, predicts the inability to return to work after stroke. METHODS: Consecutive patients aged 18--65 with a first-ever ischaemic stroke, working full time previously, were assessed neuropsychologically within the first weeks after stroke and at the 6-month follow-up. Similarly, 50 healthy demographic controls were assessed twice. The cognitive severity of stroke was operationalised as the number of initial cognitive deficits. Cognitive severity as a predictor of the inability to return to work was compared with demographic, occupational, neurological, radiological and functional data, vascular risk factors and mood state. RESULTS: The mean age of the 140 patients assessed both initially and at follow-up was 52 years. They had a mean of 13 years of education and 59% were men. At 6 months, only 41% of the patients had returned to work despite the relatively minor neurological and functional impairments of the cohort. In our model, the number of early cognitive deficits (OR=2.252, CI 1.294 to 3.918) was the only significant predictor of the inability to return to work. CONCLUSIONS: The initial cognitive severity of stroke predicts the later inability to return to work. The benefits of neuropsychological assessments within the first weeks after stroke are emphasised.
