Abstract
Background Cognitive screening tools are important in the detection of dementia, including Alzheimer's disease; however, they may contain cultural biases. Objective This review examines culture-fair cognitive screening tools and evaluates their screening accuracy, strengths, and limitations. Methods Medline, Embase, PsychINFO and CINAHL were searched. The protocol was registered on PROSPERO (CRD42021288776). Included studies used a culture-fair tool to assess cognition in older adults from varying ethnicities. Narrative synthesis was conducted. Results 28 studies were included assessing eleven different tools. The Rowland Universal Dementia Assessment Scale (RUDAS) was as accurate as the Mini-Mental State Examination (MMSE) (AUC 0.62-0.93), with a similar sensitivity (52-94%) and better specificity (70-98%), and the Multicultural Cognitive Examination (MCE) had improved screening accuracy (AUC 0.99) compared to RUDAS (AUC 0.92). The Visual Cognitive Assessment Test (VCAT) was equivalent to MMSE (AUC 0.84-0.91). The Kimberley Indigenous Cognitive Assessment tool (KICA) had AUC of 0.93-0.95; sensitivity of 90.6%, specificity 92.6%. Conclusions The RUDAS, KICA and VCAT were superior to MMSE for screening dementia in ethnic minorities. Other tools also showed good screening accuracy. Further research should be done to validate tools in different populations.

Abstract
Rowland Universal Dementia Assessment Scale (RUDAS) is a cognitive screening that evaluates older people with low educational levels. In Chile, there are no normative data to assess this population. Objective To obtain normative data on RUDAS in older Chilean people with up to 12 years of schooling, and to determine whether age and schooling years influence a person's performance on RUDAS and on the items that constitute it. Methods A group of cognitively healthy people 60 years old or over, with up to 12 schooling years was evaluated (n=135). Multiple regression models were applied to obtain normative data on RUDAS, according to age and schooling years, and to measure the effects of schooling on different items. Results Regression analysis showed that none of the items had schooling as a significant predictor, except for the visuoconstruction item. The variables age and schooling explained 12.6% (R^2=0.126) of the RUDAS total score variance. The item visuoconstruction was the most associated with the educational level (OR=1,147). Conclusion This study showed that RUDAS is a recommended instrument for evaluating older people with low educational levels. However, more studies are needed to prove the validity of the RUDAS on Chilean older people.

Mild Cognitive Impairment Is Associated with Poorer Nutritional Status on Hospital Admission and after Discharge in Acutely Hospitalized Older Patients. Geriatrics (Basel) 2022; 7:geriatrics7050095. [PMID: 36136804 PMCID: PMC9498394 DOI: 10.3390/geriatrics7050095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 09/02/2022] [Accepted: 09/06/2022] [Indexed: 11/30/2022] Open
Abstract
In acutely hospitalized older patients (≥65 years), the association between mild cognitive impairment (MCI) and malnutrition is poorly described. We hypothesized that (1) MCI is associated with nutritional status on admission and after discharge; (2) MCI is associated with a change in nutritional status; and (3) a potential association is partly explained by frailty, comorbidity, medication use, and age. We combined data from a randomized controlled trial (control group data) and a prospective cohort study (ClinicalTrials.gov: NCT01964482 and NCT03052192). Nutritional status was assessed on admission and follow-up using the Mini Nutritional Assessment—Short Form. MCI or intact cognition (noMCI) was classified by three cognitive performance tests at follow-up. Data on frailty, comorbidity, medication use, and age were drawn from patient journals. MCI (n = 42) compared to noMCI (n = 47) was associated with poorer nutritional status with an average difference of −1.29 points (CI: −2.30; −0.28) on admission and −1.64 points (CI: −2.57; −0.70) at 4-week follow-up. Only age influenced the estimates of −0.85 (CI: −1.86; 0.17) and −1.29 (CI: −2.25; −0.34), respectively. In acutely hospitalized older patients, there is an association between MCI and poorer nutritional status upon admission and four weeks after discharge. The association is partly explained by higher age.

Abstract
Objective and accurate cognitive assessment scales are essential for guiding cognitive rehabilitation following traumatic brain injury (TBI). The aim of this study was to evaluate the reliability and validity of the Rowland Universal Dementia Assessment Scale (RUDAS) for TBI and to verify the clinical application value. Fifty patients with TBI and 32 matched controls were assessed using the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and a newly developed Chinese version of RUDAS. These scales were then compared for internal consistency, inter-rater reliability, test‒retest reliability, content validity, construct validity, and diagnostic efficacy. Among the TBI group, the RUDAS demonstrated acceptable internal consistency (Cronbach's α = 0.733), high inter-rater reliability (intraclass correlation coefficients [ICCs] of 0.910‒0.999), and high test‒retest reliability (total score ICC = 0.938). The correlation coefficients between RUDAS total score and individual subscores were all > 0.5 except for body orientation (r = 0.363), indicating generally good content validity. Total RUDAS scores were moderately correlated with both MMSE total scores (r = 0.701, p < 0.001) and MoCA total scores (r = 0.778, p < 0.001), indicating good construct validity. Receiving operating characteristic curve analysis yielded comparable areas under the curve for diagnostic efficacy (RUDAS, 0.844; MMSE, 0.769; MoCA, 0.824; all p > 0.05). A RUDAS score cutoff of 23.5 distinguished TBI patients from controls with 60% sensitivity and 100% specificity. Therefore, the RUDAS demonstrates both good reliability and validity for evaluating cognitive impairments in TBI patients.

Abstract
Background: The number of people with a migration background and dementia is increasing in Europe. All patients with suspected dementia have the right to an appropriate cognitive assessment and correct diagnosis for optimal treatment and support. Rowland Universal Dementia Assessment Scale (RUDAS) cognitive screening instrument is less affected by language, culture, and educational background, and adapted for use in multicultural populations. Objective: To compare the diagnostic accuracy of RUDAS-S to the Swedish version of Mini-Mental State Examination (MMSE-SR) for detecting dementia in a multicultural group of outpatients in Swedish memory clinics. Methods: We tested 123 outpatients (36 nonnative Swedish), in 4 memory clinics in Southern Sweden with RUDAS-S to supplement the usual cognitive assessment. Results: RUDAS-S had moderate to good diagnostic performance for detecting dementia in a multicultural population in Sweden, with an area under the receiver operating characteristic curve (AUC) of 0.81. At a cutoff score <25 its sensitivity was 0.92, specificity 0.60, and accuracy 76%. The AUC for the MMSE-SR was 0.79. At a cutoff score <23 its sensitivity was 0.65, specificity 0.81, and accuracy 73%. Conclusion: RUDAS-S is at least as accurate as MMSE-SR for detecting dementia in memory clinics in Sweden and can be used for all patients undergoing a cognitive assessment, irrespective of their cultural, language, and educational background. However, there is a need for other cross-cultural cognitive tests to complement RUDAS-S to extend cognitive examination.

Abstract
Due to increasing cultural, linguistic, and educational diversity in older populations across Europe, accurate assessment of cognitive functioning in people from diverse backgrounds becomes increasingly important. This paper aims to provide a state-of-the-art review of cognitive assessment in culturally, linguistically, and educationally diverse older populations in Europe, focusing on challenges and recent advances in cross-cultural assessment. Significant work has been carried out on the identification of challenges in cognitive assessment in culturally, linguistically, and educationally diverse older populations and on development and validation of cross-cultural cognitive tests. Most research has addressed the influences of language barriers, education and literacy, and culture and acculturation and in particular, the European Cross-Cultural Neuropsychological Test Battery (CNTB) and the Rowland Universal Dementia Assessment Scale (RUDAS) are well-validated across European countries. However, cross-cultural cognitive assessment is largely still a developing field in Europe, and there is a continuing need for developments within the field.

Abstract
BACKGROUND Rowland Universal Dementia Assessment Scale (RUDAS) has demonstrated usefulness in cognitive assessment. Studies supporting the use of RUDAS as an evaluation tool in traumatic brain injury (TBI) patients remain limited. This study examined whether the Chinese version of RUDAS can be effectively applied to the cognitive assessment of TBI patients in China. OBJECTIVE To compare the performance of Mini-Mental State Examination (MMSE) and the Chinese version of RUDAS in the cognitive assessment of Chinese patients with TBI so as to provide reference for clinical use. METHODS 86 inpatients with TBI in a hospital were selected from July 2019 to July 2020 and were enrolled as the TBI group, while another 40 healthy individuals matched with age, sex and education level were selected as the control group. All subjects were assessed by trained rehabilitation physicians with MMSE and RUDAS. RESULTS (1) Compared with the control group, the scores of MMSE and RUDAS in the TBI group decreased significantly; (2) The results of MMSE and RUDAS in the TBI group were positively correlated (r = 0.611, P < 0.001); (3) Linear correlation suggested that age was negatively correlated with MMSE (r = -0.344, P = 0.001) and RUDAS (r = -0.407, P < 0.001), while education years were positively correlated with MMSE (r = 0.367, P = 0.001) and RUDAS (r = 0.375, P < 0.001). However, according to the multiple linear regression, the results of RUDAS were not affected by the years of education; (4) Receiver operating curve analysis showed that there was no significant difference in the areas under the curve between MMSE and RUDAS. The best cut-off values of MMSE and RUDAS were 27.5 and 24.5, respectively. CONCLUSIONS MMSE and RUDAS have similar diagnostic efficacy in evaluating cognitive impairment of patients with TBI. Since the Chinese version of RUDAS is not affected by the education level, it is more suitable for TBI patients in China.

Abstract
OBJECTIVE The increasing ethnic diversity in the European Union (EU) calls for adaptations to neuropsychological assessment practices. The aims of this study were to examine the current state of cross-cultural neuropsychological assessment in EU-15 countries and to provide recommendations for researchers and policy makers. METHOD Twelve experts from nine EU-15 countries participated in a Delphi consensus study involving two sequential rounds of web-based questionnaires and an in-person consensus meeting. The experts individually rated Delphi topics on the basis of importance (scale 1-10). The degree of consensus was determined by assessing first and third quartiles (Q1 and Q3) and medians. RESULTS Consensus outcomes showed the following priorities: (a) the development of tests (median importance rating 10, Q1-Q3: 9-10), (b) the collection of normative data (median importance rating 9, Q1-Q3: 8-10), and (c) more training, awareness, and knowledge regarding cross-cultural assessment among neuropsychologists in the EU (median importance rating 9, Q1-Q3: 8-10). Whereas memory tests were often available, tests measuring social cognition (median 9, Q1-Q3: 8-10) and language (median 9, Q1-Q3: 7-10) are particularly lacking. Recommendations were made regarding essential skills and knowledge necessary for cross-cultural neuropsychological assessment. CONCLUSIONS This study in a small group of experts suggests that the development and availability of cross-cultural tests and normative data should be prioritized, as well as the development and implementation of training initiatives. Furthermore, EU guidelines could be established for working with interpreters during neuropsychological assessment. Before implementing these recommendations, follow-up studies are recommended that include more minority neuropsychologists and community stakeholders.

Abstract
Background: The ageing Arctic populations raise the need for work-up of cognitive function that reflects language and cultural understandings. Aim: To translate and evaluate tools for work-up of cognitive impairment in Greenland. Methods: Step A: An expert panel was established to select tools suitable for the work-up of cognitive impairment at three different settings in Greenland. Step B: Tools were translated in a multiple-step process of independent translations with back-translation and adaptations by two independent translators and two Greenlandic physicians. Step C: a testing and validation process of the tools at three locations: the national hospital in the capital city; regional hospital in a town; health care centre in a small town. Results: Tools selected were Mini-Cog and RUDAS. Participants for testing of tools were 43 of 61 invited, of which six had dementia. RUDAS and Mini-Cog scores were associated (p < 0.001). The smoothed AUC was 0.87 (95%-CI, 0.65–0.95) for Mini-Cog and 0.90 (95%-CI, 0.76–0.97) for RUDAS. The sensitivity of Mini-Cog with a cut-off at ≤3 was 83.3%, and specificity was 62.2%. For RUDAS with a cut-off at ≤23, these were 100% and 75.7%, respectively. Conclusion: Requested tools have been translated for assessing cognitive function in the native Arctic setting. Small town residents with a Mini-Cog score of 3 or lower should be referred to a regional hospital for RUDAS, and a score of 23 or less should cause referral to the national hospital for a full work-up of cognitive function.

Abstract
The 10/66 dementia protocol was developed as a language and culture-fair instrument to estimate the prevalence of dementia in non-English speaking communities. The aim of this study was to validate the 10/66 dementia protocol in elders of Indian ethnicity born in the Fiji Islands (Fijian-Indian) living in New Zealand. To our knowledge, this is the first time a dementia diagnostic tool has been evaluated in the Fijian-Indian population in New Zealand. We translated and adapted the 10/66 dementia protocol for use in in Fijian-Indian people. Individuals (age ≥ 65) who self-identified as Fijian-Indian and had either been assessed for dementia at a local memory service (13 cases, eight controls) or had participated in a concurrent dementia prevalence feasibility study (eight controls) participated. The sensitivity, specificity, positive predictive value, and Youden’s index were obtained by comparing the 10/66 diagnosis and its sub-components against the clinical diagnosis (reference standard). The 10/66 diagnosis had a sensitivity of 92.3% (95% CI 70.3–99.5), specificity of 93.8% (95% CI 75.3–99.6), positive predictive value of 92.3% (95% CI 70.3–99.5), and negative predictive value of 93.8% (95% CI 75.3–99.6). The study results show that the Fijian-Indian 10/66 dementia protocol has adequate discriminatory abilities to diagnose dementia in our sample. This instrument would be suitable for future dementia population-based studies in the Fijian-Indian population living in Aotearoa/New Zealand or the Fiji-Islands.

Abstract
OBJECTIVES To quantitatively synthesize data on the accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) in different sociocultural settings and compare its performance to other brief screening instruments for the detection of dementia. DESIGN Systematic review and meta-analysis. Literature searches were performed in PubMed, EMBASE, and CINAHL from January 1, 2004 until September 1, 2019. SETTING Community, outpatient clinic, and hospital settings in high-, and low- and middle-income countries. PARTICIPANTS Twenty-six studies reporting diagnostic accuracy of the RUDAS were included with almost 4000 participants, including approximately 1700 patients with dementia. MEASUREMENTS Procedures for translation and cultural adaption of the RUDAS, and influence of demographic variables on diagnostic accuracy, were compared across studies. Bivariate random-effects models were used to pool sensitivity and specificity results, and diagnostic odds-ratios and the area under the hierarchical summary receiver operator characteristic curve were used to present the overall performance. RESULTS The pooled sensitivity and specificity for the detection of dementia were .82 (95% CI, .78-.86) and .83 (95% CI, .78-.87), respectively, with an area under the curve of .89. Subgroup analyses revealed that the RUDAS had comparable diagnostic performances across high-, and low- and middle-income settings (z = .63, P = .53) and in samples with a lower and higher proportion of participants with no formal education (z = -.15, P = .88). In 11 studies making direct comparison, the diagnostic performance of the RUDAS was comparable to that of the Mini-Mental State Examination (z = -.82, P = .41), with areas under the curve of .88 and .84, respectively. CONCLUSIONS The RUDAS has good diagnostic performance for detecting dementia in different sociocultural settings. Compared to other brief screening instruments, advantages of the RUDAS include its limited bias in people with limited or no formal education and a minimal need for cultural or language adaptation.

Abstract
BACKGROUND Neuropsychological tests are influenced by culture, language, level of education, and literacy, but there are few cognitive tests of which the applicability in ethnic minority populations has been studied. OBJECTIVES The aim of this study was to assess the reliability and validity of the Visual Association Test (VAT), a test of visual association memory, in a non-Western, low-educated memory clinic population. Additionally, a modified version of the VAT using colored photographs instead of line drawings was studied (mVAT). METHOD Both the original VAT and the mVAT were administered to non-Western immigrants (n = 73) from 2 multicultural memory clinics in Rotterdam, The Netherlands, and a control sample of non-demented Turkish elderly (n = 14) with low education levels (32 and 29% illiterate, respectively). RESULTS Both the VAT and the mVAT were able to discriminate persons with and without dementia (area under the curve: VAT, 0.77-0.88; mVAT, 0.85-0.95). The mVAT had more homogeneous item difficulty levels than the VAT. Administration of parallel versions of the VAT and the mVAT within the same person revealed higher scores on the mVAT (Z = -3.35, p = 0.001). CONCLUSIONS The mVAT is a reliable and valid measure of memory in non-Western immigrants. Clinicians and researchers should be aware that the memory performance of immigrants may be systematically underestimated when using tests with black-and-white line drawings, such as the original VAT.

Abstract
UNLABELLED ABSTRACTBackground:With increasing cultural diversity and growing elderly immigrant populations in Western European countries, the availability of brief cognitive screening instruments adequate for assessment of dementia in people from diverse backgrounds becomes increasingly important. The aim of the present study was to investigate diagnostic accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) in a multicultural sample and to calculate normative data as a basis for demographic adjustment of RUDAS scores. METHODS The study was a prospective international cross-sectional multi-center study. Receiver operating characteristic curve analysis was used to examine diagnostic accuracy. Regression analysis was used to assess the impact of demographic variables. RESULTS Data was collected from 341 cognitively intact participants and 80 people with dementia with a wide age- and educational range. Of the 421 included participants, 239 (57%) had immigrant background. The RUDAS had high diagnostic accuracy with an area under the curve (AUC) of 0.93. The optimal cut-off score was <25 (sensitivity 0.80, specificity 0.90). Regression analysis revealed that RUDAS scores were mainly affected by education and were unrelated to data collection site and immigrant status. Education-adjusted normative data was calculated as a basis for education adjustment of RUDAS scores. Applying education-adjusted RUDAS scores slightly but significantly improved diagnostic accuracy with an AUC of 0.95. CONCLUSION We found the RUDAS to have excellent diagnostic properties in our multicultural sample. However, we suggest that RUDAS scores should be adjusted for education to increase diagnostic accuracy and that the choice of cut-off score should be considered based on the clinical context and expected base rate of dementia.

Abstract
BACKGROUND The aim is to validate Turkish version Rowland Universal Dementia Assessment Scale (RUDAS). METHODS One hundred forty patients (>65 years) were included. Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition -V was used in all patients. Rowland Universal Dementia Assessment Scale was applied for 2 days. Results were compared with Mini-Mental State Examination; reliability, validity, and statistical values were determined. RESULTS Time validity was verified. Mini-mental state examination was correlated 45.3% in control and 73% in dementia group. Factor weights varied between 0.44 and 0.81; factor construct was verified as 6-item scoring. When 25 was cutoff point, sensitivity was 92.86% and specificity was 92.86%. Content validity index was found to be 100% by 7 specialists. Cronbach α (0.692) and test-retest reliability (intraclass correlation = 0.987) were determined. CONCLUSION Rowland Universal Dementia Assessment Scale (Turkish) is validated and verified as reliable. Test could be applied for 5 minutes approximately; results are not affected by educational status, immigrant status, and language used; however, age and gender have significant effect on results.

Abstract
Objective: To validate the Rowland Universal Dementia Assessment Scale for use in Brazil (RUDAS-BR). Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the RUDAS. A total of 135 subjects over 60 years of age were included: 65 cognitively healthy and 70 with Alzheimer’s disease (AD) according to the DSM-IV and Neurological and Communicative Disorders and Stroke/Alzheimer’s Disease and Related Disorders Association (NINCDS-ADRDA) criteria. All participants completed an interview and were screened for depression. The receiver operating characteristic curves of the RUDAS were compared with those of the Mini Mental State Examination (MMSE) regarding the sensitivity and specificity of cutoffs, taking education into consideration. Results: The areas under the curve were similar for the RUDAS-BR (0.87 [95%CI 0.82-0.93]) and the MMSE (0.84 [95%CI 0.7-0.90]). RUDAS-BR scores < 23 indicated dementia, with sensitivity of 81.5% and specificity of 76.1%. MMSE < 24 indicated dementia, with sensitivity of 72.3% and specificity of 78.9%. The cutoff score was influenced by years of education on the MMSE, but not on the RUDAS-BR. Conclusions: The RUDAS-BR is as accurate as the MMSE in screening for dementia. RUDAS-BR scores were not influenced by education. The RUDAS-BR may improve the cognitive assessment of older persons who are illiterate or of lower educational attainment.

Abstract
BACKGROUND/AIMS The aim of this study was to assess whether combining the Rowland Universal Dementia Assessment Scale (RUDAS) and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) could improve diagnostic accuracy when screening for dementia in an Arabic-speaking population with low levels of literacy. METHODS Based on data from 225 elderly participant and informant dyads, the screening performances of the two instruments were compared and three methods for combining them--'or', 'and' and 'weighted sum' rules--were assessed. RESULTS The 'weighted sum' method had a significantly better area under the curve value compared to the RUDAS used alone. The 'weighted sum' method and the 'and' rule had the highest specificity, while the 'or' rule had the best sensitivity. CONCLUSION Harnessing the RUDAS and IQCODE increased diagnostic accuracy when screening for dementia in this study population.

Abstract
OBJECTIVES Validated screening tests for dementia in Arabic are lacking. Given the low levels of education among elderly in the Middle East and North Africa region, the commonly used screening instrument, the Mini Mental State Examination, is not best suited. Alternatively, the Rowland Universal Dementia Assessment Scale (RUDAS) was especially designed to minimize the effects of cultural learning and education. The aim of this study was to validate the RUDAS in the Arabic language (A-RUDAS), evaluate its ability to screen for mild and moderate dementia, and assess the effect of education, sex, age, depression, and recruitment site on its performance. METHODS A-RUDAS was administered to 232 elderly aged ≥65 years recruited from the communities, community-based primary care clinics, and hospital-based specialist clinics. Of these, 136 had normal cognition, and 96 had dementia. Clinicians diagnosed dementia according to the Diagnostic and Statistical Manual of Mental Disorders fourth edition (DSM-IV) criteria. Interviewers, blind to the cognitive status of participants, administered A-RUDAS. The psychometric properties of A-RUDAS were examined for three cutoffs. RESULTS At the cutoff of ≤22, A-RUDAS exhibited good sensitivity (83%) and specificity (85%) with an area under the receiver operating characteristic curve of 83.95%. Adjusting for age, sex, education, depression, and recruitment site, A-RUDAS score demonstrated a high level of accuracy in screening for mild and moderate dementia against DSM-IV diagnosis. CONCLUSION The A-RUDAS is proposed for dementia screening in clinical practice and in research in Arabic-speaking populations with an optimal cutoff of ≤22.

Abstract
BACKGROUND Validated cognitive screening tools for use in urban and regional Aboriginal populations in Australia are lacking. METHODS In a cross-sectional community-based study, 235 participants were assessed on the Mini-Mental State Examination (MMSE), the Rowland Universal Dementia Assessment Scale (RUDAS) and an urban modification of the Kimberley Indigenous Cognitive Assessment (mKICA). Performance on these cognitive screening tools was compared to dementia diagnosis by clinical consensus. RESULTS All tests were culturally acceptable with good psychometric properties. Receiver operating characteristic curve analyses revealed that the MMSE and mKICA were the most accurate. CONCLUSION The MMSE is an effective cognitive screening tool in urban Aboriginal populations. The mKICA is a good alternative when illiteracy, language or cultural considerations deem it appropriate. The RUDAS also has adequate validity in this population.

Abstract
BACKGROUND Canada has a growing multinational immigrant population. Many commonly used cognitive assessment tools have known cultural biases and are difficult to use in ethnically diverse patient populations. The Rowland Universal Dementia Assessment Scale (RUDAS) is a cognitive assessment tool that was created for culturally and linguistically diverse populations. We performed a systematic review and meta-analysis to assess the psychometric characteristics of the RUDAS and to compare it with other available tools. METHODS We identified studies that assessed the psychometric properties of the RUDAS compared with a reference standard for diagnosing dementia or compared the RUDAS to other cognitive assessment tools. Two independent reviewers screened the abstracts and full-text articles and reviewed bibliographies for further references. We extracted data using standardized forms and assessed studies for risk of bias. RESULTS Our search resulted in 148 articles, from which 11 were included. The RUDAS was assessed in 1236 participants and was found to have a pooled sensitivity of 77.2% (95% confidence interval [CI] 67.4-84.5) and a pooled specificity of 85.9% (95% CI 74.8-92.6) yielding a positive likelihood ratio of 5.5 (95% CI 2.9-10.7) and a negative likelihood ratio of 0.27 (95% CI 0.17-0.40). A pooled estimate of the correlation between the RUDAS and the Mini-Mental State Examination (MMSE) was 0.77 (95% CI 0.72-0.81). Results of the RUDAS were less affected by language and education level than the MMSE. INTERPRETATION The RUDAS is a brief and freely available cognitive assessment tool with reasonable psychometric characteristics that may be particularly useful in patients with diverse backgrounds.

Abstract
Introduction The process of selecting the most appropriate cognitive assessments to use with clients presenting with symptoms of dementia is an important consideration. Are cognitive assessment results associated with the functional performance of clients presenting suspected cognitive decline? The purpose of this study was to investigate whether the Rowland Universal Dementia Assessment Scale was associated with the functional performance of clients with suspected dementia. Method A within-subjects quantitative research design was employed whereby a sample of 30 participants suspected of having dementia were recruited from three acute care hospital sites in the Melbourne metropolitan region. The Rowland Universal Dementia Assessment Scale was used to assess participants' cognitive abilities, while the Functional Independence Measure was the functional scale used. Linear regression analyses were completed. Results The six Rowland Universal Dementia Assessment Scale items were found to be significantly linked with the Functional Independence Measure total score (adjusted R2 = 0.298, p < 0.05), the Functional Independence Measure ‘cognition’ subscale score (adjusted R2 = 0.349, p < 0.05) and the Functional Independence Measure ‘physical’ subscale score (adjusted R2 = 0.244; p < 0.05). Conclusion The Rowland Universal Dementia Assessment Scale appears to be associated with the functional performance of clients with suspected dementia. The findings provide an insight into the link between cognition and everyday functional performance.

Abstract
Marginal communities, such as culturally and linguistically diverse (CALD) patients, have significantly lower rates of recruitment, accrual, and retention in cancer clinical trials. A combination of language and cultural barriers means that trial participation from CALD communities remains at suboptimal levels, which in turn favors research findings that are biased towards therapeutic effects or toxicities within the context of non-CALD populations. Here we outline some key challenges and implications for CALD patient participation in glioma research in countries such as Australia, where English is the language of governance and health services implementation. We highlight multistakeholder interventions to improve both investigator recruitment and participation of CALD communities in future glioma research, particularly in this era when global migration has come of age. Enhancing research participation of CALD communities ensures not only wider understanding of genetic heterogeneity to improve glioma outcomes but also equity in access to care.
