Dissipating the fog: Cognitive trajectories and risk factors 1 year after COVID-19 hospitalization.

INTRODUCTION: Cognitive impairment is common after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, associations between post-hospital discharge risk factors and cognitive trajectories have not been explored. METHODS: A total of 1105 adults (mean age ± SD 64.9 ± 9.9 years, 44% women, 63% White) with severe coronavirus disease 2019 (COVID-19) were evaluated for cognitive function 1 year after hospital discharge. Scores from cognitive tests were harmonized, and clusters of cognitive impairment were defined using sequential analysis. RESULTS: Three groups of cognitive trajectories were observed during the follow-up: no cognitive impairment, initial short-term cognitive impairment, and long-term cognitive impairment. Predictors of cognitive decline after COVID-19 were older age (ß = -0.013, 95% CI = -0.023;-0.003), female sex (ß = -0.230, 95% CI = -0.413;-0.047), previous dementia diagnosis or substantial memory complaints (ß = -0.606, 95% CI = -0.877;-0.335), frailty before hospitalization (ß = -0.191, 95% CI = -0.264;-0.119), higher platelet count (ß = -0.101, 95% CI = -0.185;-0.018), and delirium (ß = -0.483, 95% CI = -0.724;-0.244). Post-discharge predictors included hospital readmissions and frailty. DISCUSSION: Cognitive impairment was common and the patterns of cognitive trajectories depended on sociodemographic, in-hospital, and post-hospitalization predictors. HIGHLIGHTS: Cognitive impairment after coronavirus disease 2019 (COVID-19) hospital discharge was associated with higher age, less education, delirium during hospitalization, a higher number of hospitalizations post discharge, and frailty before and after hospitalization. Frequent cognitive evaluations for 12-month post-COVID-19 hospitalization showed three possible cognitive trajectories: no cognitive impairment, initial short-term impairment, and long-term impairment. This study highlights the importance of frequent cognitive testing to determine patterns of COVID-19 cognitive impairment, given the high frequency of incident cognitive impairment 1 year after hospitalization.

Decision-making executive function profile and performance in older adults with major depression: a case-control study.

OBJECTIVES: Decision making (DM) is a component of executive functioning, essential for choosing appropriate decisions. Executive dysfunctioning is particularly common in late-life depression, however the literature is scarce on DM. This case-control study aimed to evaluate the DM profile and performance in participants with and without unipolar major depression. METHOD: The DM profile and performance were assessed by the Melbourne Decision Making Questionnaire and the Iowa Gambling Task (IGT), respectively, in three groups of older adults from a university-based geriatric psychiatry clinic, i.e. current depression (n = 30), remitted depression (n = 43) and healthy controls (n = 59). The Hamilton Depression scale (HAM-D) 21 items, the Hamilton Anxiety scale, and the Mini-Mental State Examination were used to access depressive symptoms, anxiety symptoms, and cognitive impairment, respectively. Multinomial, nominal and binary logistic regression was used to evaluate the associations between depression, depressive symptomatology and DM. RESULTS: In comparison to the control group, patients with current depression presented higher scores in buck-passing and proscratination DM profiles. In the hypervigilance profile, there was a significant difference between current and remitted depression groups. A higher value ​in the HAM-D scale increased the probability of disadvantageous DM profiles. Depressive patients showed a tendency of a higher mean score in both disadvantageous decks (A and B) of IGT. Patients with current depression showed a worse performance compared to the remitted depression group in the IGT netscore. CONCLUSION: Older adults with current depression showed DM profiles considered maladaptive or disadvantageous compared to both remitted depression and healthy controls groups.

A 2-Minute Cognitive Screener for Predicting 1-Year Functional Recovery and Survival in Older Adults After Hip Fracture Repair.

BACKGROUND: Implementing cognitive assessment in older people admitted to hospital with hip fracture-lying in bed, experiencing pain-is challenging. We investigated the value of a quick and easy-to-administer 10-point Cognitive Screener (10-CS) in predicting 1-year functional recovery and survival after hip surgery. METHODS: Prospective cohort study comprising 304 older patients (mean age = 80.3 ± 9.1 years; women = 72%) with hip fracture consecutively admitted to a specialized academic medical center that supports secondary hospitals in Sao Paulo Metropolitan Area, Brazil. The 10-CS, a 2-minute bedside tool including temporal orientation, verbal fluency, and three-word recall, classified patients as having normal cognition, possible cognitive impairment, or probable cognitive impairment on admission. Outcomes were time-to-recovery activities of daily living (ADLs; Katz index) and mobility (New Mobility Score), and survival during 1-year after hip surgery. Hazard models, considering death as a competing risk, were used to associate the 10-CS categories with outcomes after adjusting for sociodemographic and clinical measures. RESULTS: On admission, 144 (47%) patients had probable cognitive impairment. Compared to those cognitively normal, patients with probable cognitive impairment presented less postsurgical recovery of ADLs (77% vs 40%; adjusted sub-hazard ratio [HR] = 0.44; 95% confidence interval [CI] = 0.32-0.62) and mobility (50% vs 30%; adjusted sub-HR = 0.52; 95% CI = 0.34-0.79), and higher risk of death (15% vs 40%; adjusted HR = 2.08; 95% CI = 1.03-4.20) over 1-year follow-up. CONCLUSIONS: The 10-CS is a strong predictor of functional recovery and survival after hip fracture repair. Cognitive assessment using quick and easy-to-administer screening tools like 10-CS can help clinicians make better decisions and offer tailored care for older patients admitted with hip fracture.

Programa Hospital Seguro para a Pessoa Idosa: estudo observacional do impacto na redução de declínio funcional / Safe Hospital Program for the Elderly Person: an observational study on the impact in reducing functional decline / Programa Hospital Seguro para Personas Ancianas: estudio observacional de impacto en la reducción del deterioro funcional

Ao ser hospitalizado, o idoso apresenta maior risco de complicações e declínio funcional. O presente estudo avaliou os resultados do Programa Hospital Seguro para a Pessoa Idosa. A intervenção foi realizada em um hospital filantrópico da cidade de São Paulo, Brasil, por meio de uma estratégia de implantação estruturada em 10 passos, incluindo rastreio de fragilidade, avaliação multidimensional, plano terapêutico singular, implementação de protocolos e estratégias de gestão de alta. Foram analisadas ao longo de dois anos 865 internações de idosos frágeis. Indicadores de processo e de resultado foram comparados entre o primeiro ano (período de implementação) e o segundo ano (período de consolidação). A comparação dos indicadores entre os dois períodos revelou que o programa melhorou os processos assistenciais fundamentais na qualidade do cuidado para essa população, incluindo reabilitação motora iniciada nas primeiras 72 horas (74,1 vs. 84,3%; p < 0,001), triagem de risco de broncoaspiração (38,5 vs. 82,8%; p < 0,001) e suplementação nutricional oral (55,6 vs. 76,4%; p < 0,001). A taxa de declínio funcional, que era 17,2% no ano de implantação, caiu para 11,7% no ano de consolidação, com diferença significativa após ajuste em modelo multivariável (p = 0,009). Em conclusão, desenvolvemos um programa factível para a realidade dos hospitais brasileiros e que pode ser reproduzido em outros centros usando-se uma metodologia sistematizada de implantação. Os resultados relativos aos indicadores de processos assistenciais e desfechos clínicos parecem promissores. A disseminação dessa iniciativa deve ser considerada no planejamento das políticas de saúde pública para a rede hospitalar.

Hospitalized elderly persons experience increased risk of complications and functional decline. The current study assessed the results of the Safe Hospital Program for the Elderly Person. The intervention was conducted in a charitable hospital in the city of São Paulo, Brazil, using a 10-step structured implementation strategy, including screening for frailty, multidimensional evaluation, unique treatment plan, implementation of protocols, and discharge management strategies. The study analyzed 865 hospitalizations of frail elders over the course of two years. Process and results indicators were compared between the first year (implementation) and second year (consolidation). Comparison of the indicators between the two periods showed that the program improved fundamental processes in care for this population, including motor rehabilitation initiated in the first 72 hours (74.1 vs. 84.3%; p < 0.001), screening for risk of bronchial aspiration (38.5 vs. 82.8%; p < 0.001), and oral nutritional supplementation (55.6 vs. 76.4%; p < 0.001). The functional decline rate, which was 17.2% in the implementation year, decreased to 11.7% in the consolidation year, with a significant difference after adjusting in the multivariate model (p = 0.009). In conclusion, we developed a feasible program for the reality of Brazilian hospitals and that can be reproduced in other centers through a systematized implementation methodology. The results pertaining to patient care indicators and clinical outcomes appear promising. This initiative's dissemination should be considered in public health policy planning for the hospital network.

COVID-19 is not over and age is not enough: Using frailty for prognostication in hospitalized patients.

BACKGROUND: Frailty screening using the Clinical Frailty Scale (CFS) has been proposed to guide resource allocation in acute care settings during the pandemic. However, the association between frailty and coronavirus disease 2019 (COVID-19) prognosis remains unclear. OBJECTIVES: To investigate the association between frailty and mortality over 6 months in middle-aged and older patients hospitalized with COVID-19 and the association between acute morbidity severity and mortality across frailty strata. DESIGN: Observational cohort study. SETTING: Large academic medical center in Brazil. PARTICIPANTS: A total of 1830 patients aged ≥50 years hospitalized with COVID-19 (March-July 2020). MEASUREMENTS: We screened baseline frailty using the CFS (1-9) and classified patients as fit to managing well (1-3), vulnerable (4), mildly (5), moderately (6), or severely frail to terminally ill (7-9). We also computed a frailty index (0-1; frail >0.25), a well-known frailty measure. We used Cox proportional hazards models to estimate the association between frailty and time to death within 30 days and 6 months of admission. We also examined whether frailty identified different mortality risk levels within strata of similar age and acute morbidity as measured by the Sequential Organ Failure Assessment (SOFA) score. RESULTS: Median age was 66 years, 58% were male, and 27% were frail to some degree. Compared with fit-to-managing-well patients, the adjusted hazard ratios (95% confidence interval [CI]) for 30-day and 6-month mortality were, respectively, 1.4 (1.1-1.7) and 1.4 (1.1-1.7) for vulnerable patients; 1.5 (1.1-1.9) and 1.5 (1.1-1.8) for mild frailty; 1.8 (1.4-2.3) and 1.9 (1.5-2.4) for moderate frailty; and 2.1 (1.6-2.7) and 2.3 (1.8-2.9) for severe frailty to terminally ill. The CFS achieved outstanding accuracy to identify frailty compared with the Frailty Index (area under the curve = 0.94; 95% CI = 0.93-0.95) and predicted different mortality risks within age and acute morbidity groups. CONCLUSIONS: Our results encourage the use of frailty, alongside measures of acute morbidity, to guide clinicians in prognostication and resource allocation in hospitalized patients with COVID-19.

Prospective GERiatric Observational (ProGERO) study: cohort design and preliminary results.

BACKGROUND: The demographic changes in Brazil as a result of population aging is one of the fastest in the world. The far-reaching new challenges that come with a large older population are particularly disquieting in low- and middle-income countries (LMICs). Longitudinal studies must be completed in LMICs to investigate the social and biological determinants of aging and the consequences of such demographic changes in their context. Therefore, we designed the Prospective GERiatric Observational (ProGERO) study, a longitudinal study of outpatient older adults in São Paulo, Brazil, to collect data both on aging and chronic diseases, and investigate characteristics associated with adverse outcomes in this population. METHODS: The ProGERO study takes place in a geriatric outpatient clinic in the largest academic medical center in Latin America. We performed baseline health examinations in 2017 and will complete subsequent in-person visits every 3 years when new participants will also be recruited. We will use periodic telephone interviews to collect information on the outcomes of interest between in-person visits. The baseline evaluation included data on demographics, medical history, physical examination, and comprehensive geriatric assessment (CGA; including multimorbidity, medications, social support, functional status, cognition, depressive symptoms, nutritional status, pain assessment, frailty, gait speed, handgrip strength, and chair-stands test). We used a previously validated CGA-based model to rank participants according to mortality risk (low, medium, high). Our selected outcomes were falls, disability, health services utilization (emergency room visits and hospital admissions), institutionalization, and death. We will follow participants for at least 10 years. RESULTS: We included 1336 participants with a mean age of 82 ± 8 years old. Overall, 70% were women, 31% were frail, and 43% had a Charlson comorbidity index score ≥ 3. According to our CGA-based model, the incidence of death in 1 year varied significantly across categories (low-risk = 0.6%; medium-risk = 7.4%; high-risk = 17.5%; P < 0.001). CONCLUSION: The ProGERO study will provide detailed clinical data and explore the late-life trajectories of outpatient older patients during a follow-up period of at least 10 years. Moreover, the study will substantially contribute to new information on the predictors of aging, senescence, and senility, particularly in frail and pre-frail outpatients from an LMIC city.

Decision-making profile in older adults: the influence of cognitive impairment, premorbid intelligence and depressive symptoms.

OBJECTIVE: Decision-making (DM) is a component of executive functioning. DM is essential to make proper decisions regarding important life and health issues. DM can be impaired in cognitive disorders among older adults, but current literature is scarce. The aim of this study was to evaluate the DM profile in participants with and without cognitive impairment. DESIGN: Cross-sectional analysis of a cohort study on cognitive aging. PARTICIPANTS: 143 older adults. SETTING: University-based memory clinic. METHODS: Patients comprised three groups after inclusion and exclusion criteria: healthy controls (n=29), mild cognitive impairment (n=81) and dementia (n=33). Participants were evaluated using an extensive neuropsychological protocol. DM profile was evaluated by the Melbourne Decision Making Questionnaire. Multinomial logistic regression was used to evaluate associations between age, sex, educational level, estimated intelligence quotient (IQ), cognitive disorders, depressive or anxiety symptoms, and the DM profiles. RESULTS: The most prevalent DM profile was the vigilant type, having a prevalence of 64.3%. The vigilant profile also predominated in all three groups. The multinomial logistic regression showed that the avoidance profile (i.e. buck-passing) was associated with a greater presence of dementia (p=0.046) and depressive symptoms (p=0.024), but with less anxious symptoms (p=0.047). The procrastination profile was also associated with depressive symptoms (p=0.048). Finally, the hypervigilant profile was associated with a lower pre-morbid IQ (p=0.007). CONCLUSION: Older adults with cognitive impairment tended to make more unfavorable choices and have a more dysfunctional DM profile compared to healthy elders.

Functional health literacy in hypertensive elders at primary health care.

OBJECTIVE: to assess the relationship between inadequate functional health literacy and inadequate blood pressure control in older people with hypertension in Primary Health Care. METHOD: a cross-sectional study with sample calculated at 392. SAHLPA-18 tool was used for functional health literacy; blood pressure was measured; sociodemographic and clinical data were collected. Hierarchical logistic regression was used. RESULTS: (high) inadequate blood pressure and (low) functional inadequate health literacy were present in 41.6% and 54.6% of the people, respectively. Factors associated with inadequate blood pressure were: inadequate functional health literacy, black-brown skin color, overweight-obesity, hypertension diagnosis time, non-adherence to exercise/diet, drug treatment. Schooling had no association with inadequate blood pressure. CONCLUSION: hypertensive elderly people with inadequate health literacy were more likely to have inadequate blood pressure. Thus, health professionals need to value functional health literacy as a possible component to control blood pressure.

Delirium and post-discharge dementia: results from a cohort of older adults without baseline cognitive impairment.

OBJECTIVES: to investigate the association between delirium occurrence in acutely ill older adults and incident dementia after hospital discharge. METHODS: retrospective cohort study examining acutely ill older adults aged +60 years and consecutively admitted to the geriatric ward of a tertiary university hospital from 2010 to 2016. Inclusion criteria were absence of baseline cognitive decline on admission and documented clinical follow-up of +12 months after discharge. Admission data were collected from our local database, including results from a standardized comprehensive geriatric assessment completed for every patient. Pre-existing cognitive decline was identified based on clinical history, CDR and IQCODE-16. Delirium was diagnosed using short-CAM criteria, while post-discharge dementia after 12 months was identified based on medical records' review. We used competing-risk proportional-hazard models to explore the association between delirium and post-discharge dementia. RESULTS: we included 309 patients. Mean age was 78 years, and 186 (60%) were women. Delirium was detected in 66 (21%) cases. After a median follow-up of 24 months, 21 (32%) patients who had experienced delirium progressed with dementia, while only 38 (16%) of those without delirium had the same outcome (P = 0.003). After adjusting for possible confounders, delirium was independently associated with post-discharge dementia with a sub-hazard ratio of 1.94 (95%CI = 1.10-3.44; P = 0.022). CONCLUSION: one in three acutely ill older adults who experienced delirium in the hospital developed post-discharge dementia during follow-up. Further understanding of delirium as an independent and potentially preventable risk factor for cognitive decline emphasizes the importance of systematic initiatives to fight it.

Development of a word accentuation test for predicting cognitive performance in Portuguese-speaking populations.

The Word Accentuation Test (WAT) has been used to predict premorbid intelligence and cognitive performance in Spanish-speaking populations. It requires participants to read a list of words without the accent marks that indicate the stressed syllable. Label="OBJECTIVE">As Portuguese pronunciation is also strongly based on accent marks, our aim was to develop a Brazilian version of the WAT. METHODS An initial pool of 60 items was constructed and a final version of 40 items (named WAT-Br) was derived by item response theory. A sample of 206 older adults underwent the WAT-Br and a standardized neuropsychological battery. Independent ratings were performed by two observers in 58 random participants. RESULTS The items showed moderate to high discrimination (α between 0.93 and 25.04) and spanned a wide range of difficulty (ß between -2.07 and 1.40). The WAT-Br was shown to have an excellent internal consistency (Kuder-Richardson Formula 20 = 0.95) and inter-rater reliability (intraclass correlation coefficient = 0.92). It accounted for 61% of the variance in global cognitive performance. CONCLUSION A version of the WAT for Portuguese-speaking populations was developed and proved to be a valuable tool for estimating cognitive performance.

Requer que os sujeitos leiam uma lista de palavras sem os sinais gráficos de acentuação que indicam a sílaba tônica. Objetivo: Como a pronúncia da língua portuguesa também é fortemente baseada em acentos gráficos, nosso objetivo foi desenvolver uma versão brasileira do TAP. Métodos: Um conjunto inicial de 60 itens foi construído e uma versão final de 40 itens (denominada TAP-Br) foi derivada por teoria da resposta ao item. Uma amostra de 206 idosos foi submetida ao TAP-Br e a uma bateria neuropsicológica padronizada. Registros de pontuação independentes foram realizados por dois observadores em uma subamostra de 58 participantes aleatórios. Resultados: Os itens apresentaram moderada a alta discriminação (α entre 0,93 e 25,04) e abrangeram uma ampla gama de dificuldades (β entre −2,07 e 1,40). O TAP-Br apresentou excelente consistência interna (Fórmula de Kuder-Richardson 20 = 0,95) e confiabilidade inter-examinador (Coeficiente de Correlação Intraclasse = 0,92). O escore do TAP-Br explicou 61% da variância do desempenho cognitivo global. Conclusão: Uma versão do TAP para as populações de língua portuguesa foi desenvolvida e mostrou-se uma ferramenta útil para estimar desempenho cognitivo.

10-Minute Targeted Geriatric Assessment Predicts Disability and Hospitalization in Fast-Paced Acute Care Settings.

BACKGROUND: Limited time and resources hinder the use of comprehensive geriatric assessment in acute contexts. We investigated the predictive value of a 10-minute targeted geriatric assessment (10-TaGA) for adverse outcomes over 6 months among acutely ill older outpatients. METHODS: Prospective study comprising 819 acutely ill outpatients (79.2 ± 8.4 years; 63% women) in need of intensive management (eg, intravenous therapy, laboratory test, radiology) to avoid hospitalization. The 10-TaGA provided a validated measure of cumulative deficits. Previously established 10-TaGA cutoffs defined low (0-0.29), medium (0.30-0.39), and high (0.40-1) risks. To estimate whether 10-TaGA predicts new dependence in activities of daily living and hospitalization over the next 6 months, we used hazard models (considering death as competing risk) adjusted for standard risk factors (sociodemographic factors, Charlson comorbidity index, and physician estimates of risk). Differences among areas under receiver operating characteristic curves (AUROC) examined whether 10-TaGA improves outcome discrimination when added to standard risk factors. RESULTS: Medium- and high-risk patients, according to 10-TaGA, presented a higher incidence of new activities of daily living dependence (21% vs 7%, adjusted subhazard ratio [aHR] = 2.4, 95% CI = 1.3-4.5; 40% vs 7%, aHR = 5.0, 95% CI = 2.8-8.7, respectively) and hospitalization (27% vs 13%, aHR = 2.0, 95% CI = 1.2-3.3; 37% vs 13%, aHR = 2.9, 95% CI = 1.8-4.6, respectively) than low-risk patients. The 10-TaGA remarkably improved the discrimination of models that incorporated standard risk factors to predict new activities of daily living dependence (AUROC = 0.76 vs 0.71, p < .001) and hospitalization (AUROC = 0.71 vs 0.68, p < .001). CONCLUSIONS: The 10-TaGA is a practical and efficient comprehensive geriatric assessment tool that improves the prediction of adverse outcomes among acutely ill older outpatients.

Effects of Adjuvant Chemotherapy on Cognitive Function of Patients With Early-stage Colorectal Cancer.

PURPOSE: Chemotherapy-related cognitive impairment can occur in cancer survivors after treatment, especially those patients who have undergone chemotherapy for breast cancer. The frequency and to what extent such toxicity develops in colorectal cancer (CRC) survivors is unknown. The present prospective study evaluated the effects of adjuvant chemotherapy on the cognitive performance of patients with localized CRC compared with a control group who had not undergone chemotherapy. PATIENTS AND METHODS: Consecutive patients with localized stage II and III CRC completed neuropsychological assessments, self-reported cognitive complaint questionnaires, and depressive symptom evaluations before starting fluoropyrimidine-based adjuvant chemotherapy and after 12 months. Blood was collected for apolipoprotein E genotyping. Diffusion tensor imaging data were acquired from a subset of participants at both evaluation points. RESULTS: From December 2012 to December 2014, 137 patients were approached and 85 were included. Of these 85 patients, 49 had undergone chemotherapy and 26 had not, in accordance with the standard recommendations for adjuvant therapy for CRC. The mean age was 62.5 ± 9.4 years, 60% were men, and the mean educational attainment was 7.6 ± 3.7 years. No difference was found in the global composite score (P = .38), attention (P = .84), or memory (P = .97) between the 2 groups during the follow-up period (mean ± standard deviation, 375 ± 29 days). However, a statistically significant difference was found for executive function after adjustment for age, sex, education, and depressive symptoms at baseline (ß -1.80; 95% confidence interval, -3.50 to -0.11; P = .04), suggesting worse performance for the chemotherapy group. For the 32 patients who had undergone magnetic resonance imaging, tract-based spatial statistics did not show voxelwise significant differences in structural brain connectivity at baseline or during follow-up. Apolipoprotein E polymorphisms were not predictive of cognitive dysfunction. CONCLUSION: Patients with CRC who received adjuvant 5-fluorouracil with or without oxaliplatin presented with a decline in executive function after 12 months compared with patients with localized disease who had not received chemotherapy.

Targeted Geriatric Assessment for Fast-Paced Healthcare Settings: Development, Validity, and Reliability.

OBJECTIVES: To develop and examine the validity and reliability of a targeted geriatric assessment (TaGA) for busy healthcare settings. DESIGN: The TaGA was developed through the consensus of experts (Delphi technique), and we investigated its construct validity and reliability in a cross-sectional study. SETTING: Geriatric day hospital specializing in acute care in Brazil. PARTICIPANTS: Older adults (N = 534) aged 79.5 ± 8.4, 63% female, consecutively admitted to the geriatric day hospital. MEASUREMENTS: The Frailty Index (FI), Physical Frailty Phenotype, and Identification of Seniors at Risk (ISAR) were used to explore the TaGA's validity. External scales were used to investigate the validity of each matched TaGA domain. The interrater reliability and time to complete the instrument were tested in a 53-person subsample. RESULTS: In 3 rounds of opinion, experts achieved consensus that the TaGA should include 10 domains (social support, recent hospital admissions, falls, number of medications, basic activities of daily living, cognitive performance, self-rated health, depressive symptoms, nutritional status, gait speed). They arrived at sufficient agreement on specific tools to assess each domain. A single numerical score from 0 to 1 expressed the cumulative deficits across the 10 domains. The TaGA score was highly correlated with the FI (Spearman coefficient = 0.79, 95% confidence interval (CI)=0.76-0.82) and discriminated between frail and nonfrail individuals better than the ISAR (area under the receiver operating characteristic curve 0.84 vs 0.72; P < .001). The TaGA score also had excellent interrater reliability (intraclass correlation coefficient = 0.92, 95% CI=0.87-0.95). Mean TaGA administration time was 9.5 ± 2.2 minutes. CONCLUSION: The study presents evidence supporting the TaGA's validity and reliability. This instrument may be a practical and efficient approach to screening geriatric syndromes in fast-paced healthcare settings. Future research should investigate its predictive value and effect on care.

Normative data for the Montreal Cognitive Assessment (MoCA) and the Memory Index Score (MoCA-MIS) in Brazil: Adjusting the nonlinear effects of education with fractional polynomials.

OBJECTIVE: To provide age-corrected and education-corrected norms for the Montreal Cognitive Assessment (MoCA) and the Memory Index Score (MoCA-MIS) in Brazil. METHODS: Community-dwelling outpatients were enrolled if they had no history of neurologic or psychiatric diseases and were not taking any drugs with effects on the central nervous system. Dementia has been excluded with the Functional Activities Questionnaire. The final sample consisted of 597 cognitively healthy Brazilians aged 50 to 90 years. To account for nonlinear relationships, we have used fractional polynomials that provide a flexible parameterization for continuous variables. RESULTS: According to the original proposed cutoff (≤25 points), 87% of our sample would be considered impaired. Even using a more conservative suggestion (≤22 points), 67% of our normative sample would be regarded as impaired. These data reinforce the need of adjusting cutoffs for schooling in populations with heterogeneous educational backgrounds. MoCA scores presented a nonlinear positive association with education tending to a plateau at higher levels (P < 0.001). On the other hand, MoCA-MIS scores presented a nonlinear negative relationship with age, with an accelerated pattern at higher age levels (P < 0.001). CONCLUSIONS: We presented normative data for the MoCA and the MoCA-MIS that will facilitate the use of the test in Brazil and, potentially, in other populations with substantial proportions of low-educated individuals. Moreover, we described a systematic approach for adjusting the effects of age and education using fractional polynomials and provided suggestions on how to account for the nonlinear relationship that is frequently encountered between demographic factors and measures of cognitive performance.
