Interrater Reliability Coefficients

The psychometric properties of the Hooper Visual Organization Test (VOT) have not been well investigated. Here the authors present internal consistency and interrater reliability coefficients, and an item analysis, using data from a sample ( N = 281) of "cognitively impaired" and "cognitively intact" patients, and patients with undetermined cognitive status. Coefficient alpha for the VOT total sample was .882. An item analysis found that 26 of the 30 items were good at discriminating among patients. Also, the interrater reliabilities for three raters (.992), two raters (.988), and one rater (.977) were excellent. Therefore, the judgmental scoring of the VOT does not interfere significantly with its clinical utility. The authors conclude that the VOT is a psychometrically sound test.

Introduction The number of patents with dementia increases among hip fracture patients. Cognitive dysfunction is defined as a premorbid state which is potentionally negatively related to short-term functional outcome. Objective To assess the relationship between cognitive status on admission and functional gain during an early rehabilitation period in elderly hip fracture patients. Methods Forty-five elderly patients with surgically treated hip fracture were examined. Cognitive status was assessed by the Mini Mental State Examination (MMSE) at admission; functional status was assessed by the motor subscale of Functional Independence Measure (FIM) at admission and before discharge, while absolute functional gain was determined by the motor FIM gain (FIM discharge - FIM admission). Absolute functional gain was analyzed in respect to cognitive status. Results Both cognitively impaired and cognitively intact hip fracture patients exhibited overall FIM motor improvements, as well as functional gains in specific FIM motor areas (p<0.01). Absolute functional gain, however, was higher in 1) cognitively intact compared to cognitively impaired patients (p<0.01), and 2) cognitively moderately impaired patients compared to severely cognitively impaired patients (p<0.01). No difference in functional gain was detected between the patients with moderately cognitively impaired compared to the cognitive intact patients (p>0.05). Conclusion The systematic use of MMSE identifies cognitively impaired hip fracture patients, and effectively predicts their short-term functional outcome. A higher admission cognitive status is related to a more favorable short term rehabilitation outcome. In spite of cognitive impairment, elderly patients with hip fracture can benefit from participation in rehabilitation programmes. The systematic identification of cognitively impaired hip fracture patients at admission facilitates optimal treatment and rehabilitation, and thus enables the best achievable outcome to be reached.

AbstractObjectives: 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)

Minnesota’s Return to Community Initiative (RTCI) assists private-pay nursing home (NH) residents to return to the community. Using data from a 1-year admission cohort of RTCI-targeted NH residents, we examined why residents who at admission expressed a desire for discharge, were paying privately, and had relatively low-care needs chose to remain in the NH. Characteristics of those who remained were compared with those who discharged using logistic regression, and barriers to discharge were summarized. Residents who were older, more cognitively impaired (OR = 1.8), unmarried (OR = 1.4), had behavior problems (OR = 1.6), or diagnosed with dementia (OR = 2.0) were more likely to remain than discharge to the community. Between admission and their 90-day assessment, residents remaining in the facility had a small decline in cognitive status, yet their continence improved and they became more independent in activities of daily living (ADLs). Seventy-four percent reported a perception of health-related barriers to discharge.

Introduction: The Montreal Cognitive Assessment (MoCA) is a cognitive screening test widely used in clinical practice and suited for the detection of Mild Cognitive Impairment (MCI). The aims were to evaluate the psychometric properties of the Persian MoCA as a screening test for mild cognitive dysfunction in Iranian older adults and to assess its accuracy as a screening test for MCI and mild Alzheimer disease (AD). Method: One hundred twenty elderly with a mean age of 73.52 ± 7.46 years participated in this study. Twenty-one subjects had mild AD (MMSE score ≤21), 40 had MCI, and 59 were cognitively healthy controls. All the participants were administered the Mini-Mental State Examination (MMSE) to evaluate their general cognitive status. Also, a battery of comprehensive neuropsychological assessments was administered. Results: The mean score on the Persian version of the MoCA and the MMSE were 19.32 and 25.62 for MCI and 13.71 and 22.14 for AD patients, respectively. Using an optimal cutoff score of 22 the MoCA test detected 86% of MCI subjects, whereas the MMSE with a cutoff score of 26 detected 72% of MCI subjects. In AD patients with a cutoff score of 20, the MoCA had a sensitivity of 94% whereas the MMSE detected 61%. The specificity of the MoCA was 70% and 90% for MCI and AD, respectively. Discussion: The results of this study show that the Persian version of the MoCA is a reliable screening tool for detection of MCI and early stage AD. The MoCA is more sensitive than the MMSE in screening for cognitive impairment, proving it to be superior to MMSE in detecting MCI and mild AD.

Using Data

Diffuse gliomas are a heterogeneous group of tumors with aggressive biological behavior and a lack of effective treatment methods. Despite new molecular findings, the differences between pathohistological types still require better understanding. In this in silico analysis, we investigated AKT1, AKT2, AKT3, CHUK, GSK3β, EGFR, PTEN, and PIK3AP1 as participants of EGFR-PI3K-AKT-mTOR signaling using data from the publicly available cBioPortal platform. Integrative large-scale analyses investigated changes in copy number aberrations (CNA), methylation, mRNA transcription and protein expression within 751 samples of diffuse astrocytomas, anaplastic astrocytomas and glioblastomas. The study showed a significant percentage of CNA in PTEN (76%), PIK3AP1 and CHUK (75% each), EGFR (74%), AKT2 (39%), AKT1 (32%), AKT3 (19%) and GSK3β (18%) in the total sample. Comprehensive statistical analyses show how genomics and epigenomics affect the expression of examined genes differently across various pathohistological types and grades, suggesting that genes AKT3, CHUK and PTEN behave like tumor suppressors, while AKT1, AKT2, EGFR, and PIK3AP1 show oncogenic behavior and are involved in enhanced activity of the EGFR-PI3K-AKT-mTOR signaling pathway. Our findings contribute to the knowledge of the molecular differences between pathohistological types and ultimately offer the possibility of new treatment targets and personalized therapies in patients with diffuse gliomas.

The aims of this study were to 1) determine if continuous eruption occurs in the maxillary teeth, 2) assess the magnitude of the continuous eruption, and 3) evaluate the effects of continuous eruption on the different periodontal parameters by using data from the population-based cohort of the Study of Health in Pomerania (SHIP). The jaw casts of 140 participants from the baseline (SHIP-0) and 16-y follow-up (SHIP-3) were digitized as 3-dimensional models. Robust reference points were set to match the tooth eruption stage at SHIP-0 and SHIP-3. Reference points were set on the occlusal surface of the contralateral premolar and molar teeth, the palatal fossa of an incisor, and the rugae of the hard palate. Reference points were combined to represent 3 virtual occlusal planes. Continuous eruption was measured as the mean height difference between the 3 planes and rugae fix points at SHIP-0 and SHIP-3. Probing depth, clinical attachment levels, gingiva above the cementoenamel junction (gingival height), and number of missing teeth were clinically assessed in the maxilla. Changes in periodontal variables were regressed onto changes in continuous eruption after adjustment for age, sex, number of filled teeth, and education or tooth wear. Continuous tooth eruption >1 mm over the 16 y was found in 4 of 140 adults and averaged to 0.33 mm, equaling 0.021 mm/y. In the total sample, an increase in continuous eruption was significantly associated with decreases in mean gingival height ( B = −0.34; 95% CI, −0.65 to −0.03). In a subsample of participants without tooth loss, continuous eruption was negatively associated with PD. This study confirmed that continuous eruption is clearly detectable and may contribute to lower gingival heights in the maxilla.

Abstract This symposium takes an interdisciplinary perspective in order to address psychological and behavioral benefits of various arts-based programs for older adults including persons living with dementia. Presenters in this symposium specialize in diverse disciplines including psychology, social work, cognitive neuroscience, education, and sociology. Using novel approaches and various research methods, the presenters will speak to the specific outcomes of arts-based interventions. The positive outcomes include: 1) improved cognitive health rediscovered identities among cognitively normal older adults; and 2) better communication and reduced agitation for persons with dementia. The first two presentations concern cognitively intact participants. Brown will present a mixed-methods study that examined cognitive benefits and differential experiences of 11 older adults who participated in a 12-week, arts-based intervention. Chow will identify the themes in the ‘Tree of Life’ drawings of 144 Hong Kong Chinese older adults, who re-authored their sense of self transcending life challenges. Next, Mohan will discuss results from an analysis of communication exchanges among 6 older participants in a 6-week, creative group storytelling program (TimeSlips) offered in a memory care community. Halpin-Healy will explain the research-based practices used in museum programming (Arts & Minds) for persons with dementia and their care partners. She will summarize the assessments of the programs that have served approximately 500 participants over a decade. As a discussant, Kim will summarize common threads that lead to effective arts-based interventions for older adults regardless of their cognitive status. She will also highlight implications regarding the benefits of arts-based interventions in late life development.
