- Frailty Modifies the Association of Hypertension With Cognition in Older Adults: Evidence From the ELSI-Brazil(2021) ALIBERTI, Marlon J. R.; SZLEJF, Claudia; LIMA-COSTA, Maria Fernanda; ANDRADE, Fabiola B. de; ALEXANDRE, Tiago S.; FERRI, Cleusa P.; SUEMOTO, Claudia K.Background: The relationship between hypertension and cognition in later life is controversial. We investigated whether the association of hypertension with cognition differs in older adults according to the frailty status using cross-sectional data from the Brazilian Longitudinal Study of Aging, a nationally representative sample of adults aged >= 50 years. Method: Hypertension was defined by a medical diagnosis or measured blood pressure >= 140/90 mm Hg. Frailty status was assessed using the Cardiovascular Health Study criteria. We estimated the association of hypertension and systolic and diastolic blood pressure with global cognition, orientation, memory, and verbal fluency z-scores, using multiple linear regression models. We also investigated interactions between hypertension and frailty on cognitive performance and impairment. Results: We evaluated 8609 participants (mean age = 61.9 +/- 9.6 years, 53% women). Participants with hypertension (59% of adults aged 50-64 and 77% of those aged >= 65 years) had poorer scores for global cognitive performance than those without hypertension, especially among adults aged 50-64 years (beta = -0.09; 95% confidence interval = -0.15, -0.04; p = .001). However, frailty modified the associations of hypertension with cognitive performance and impairment in those aged >= 65 years (p-values for interaction = .01 and .02, respectively). Among nonfrail older adults, hypertension was associated with cognitive impairment. In contrast, among frail older adults, hypertension was related to better global and memory cognitive z-scores. Conclusions: Hypertension was associated with worse cognitive performance. Among older adults, hypertension was related to cognitive impairment only in nonfrail participants. Frailty evaluation may help clinicians offer personalized hypertension management in older adults.
conferenceObject Bullseye - targeted geriatric assessment improves prognostication in hospitalized older adults(2021) AVELINO-SILVA, T. J.; CAMPORA, F.; CURIATI, J. A.; JACOB-FILHO, W.; ALIBERTI, M.- The Impact of Frailty on the Relationship between Life-Space Mobility and Quality of Life in Older Adults During the COVID-19 Pandemic(2021) SARAIVA, M. D.; APOLINARIO, D.; AVELINO-SILVA, T. J.; TAVARES, C. De Assis Moura; GATTAS-VERNAGLIA, I. F.; FERNANDES, C. Marques; RABELO, L. M.; YAMAGUTI, S. Tavares Fernandes; KARNAKIS, T.; KALIL-FILHO, R.; JACOB-FILHO, W.; ALIBERTI, Marlon Juliano RomeroBackground The COVID-19 pandemic has led to abrupt restrictions of lile-space mobility. The impact of shelter-in-place orders on older adults' health and well-being is still unclear. Objective To investigate the relationship between life-space mobility and quality of life (QoL) in older adults with and without frailty during the COVID-19 pandemic. Design Multicenter prospective cohort study based on structured telephone interviews. Setting Four geriatric outpatient clinics in the metropolitan area of Sao Paulo, Brazil. Participants 557 community-dwelling adults aged 60 years and older. Measurements The Life-Space Assessment was used to measure community mobility before and during the COVID-19 pandemic, and a previously validated decrease of >= 5 points defined restricted life-space mobility. Frailty was assessed through the FRAIL (fatigue, resistance, ambulation, illnesses, and loss of weight) scale. The impact of shelter-in-place orders on QoL was evaluated with the question << How is the COVID-19 pandemic affecting your QoL?>>, to which participants could respond << not at all >>, << to some extent >>, or << to a great extent >>. We used ordinal logistic regressions to investigate the relationship between restricted life-space mobility and impact on QoL, adjusting our analyses for demographics, frailty, comorbidities, cognition, functionality, loneliness, depression, and anxiety. We explored whether frailty modified the association between life-space mobility and impact on QoL. Results Participants were on average 80 +/- 8 years old, 65% were women, and 33% were frail. The COVID-19 quarantine led to a restriction of community mobility in 79% of participants and affected the QoL for 77% of participants. We found that restricted life-space mobility was associated with impact on QoL in older adults during the pandemic, although frailty modified the magnitude of the association (P-value for interaction=0.03). Frail participants who experienced restricted life-space mobility had twice the odds of reporting an impact on QoL when compared with non-frail individuals, with respective adjusted odds ratios of 4.20 (95% CI=2.36-7.50) and 2.18 (95% CI=1.33-3.58). Conclusion Older adults experienced substantial decreases in life-space mobility during the COVID-19 pandemic, and this unexpected change impacted their QoL. Providers should be particularly watchful for the consequences of abrupt life-space restrictions on frail individuals.
- Divergent: Age, Frailty, and Atypical Presentations of COVID-19 in Hospitalized Patients(2021) POCO, Paula Cristina Eiras; ALIBERTI, Marlon Juliano Romero; DIAS, Murilo Bacchini; TAKAHASHI, Silvia de Fatima; LEONEL, Fabio Campos; ALTONA, Marcelo; VENYS, Amanda Lagreca; SHIN-IKE, Isabela Akie; GARCIA, Bianca Aparecida; SUMITA, Leticia Harumi; LIMA, Lara Mune de Oliveira; GARCEZ, Flavia Barreto; AVELINO-SILVA, Thiago JunqueiraBackground: Although frailty has been associated with atypical manifestations of infections, little is known about COVID-19 presentations in hospitalized frail patients. We aimed to investigate the association between age, frailty, and clinical characteristics of COVID-19 in hospitalized middle-aged and older adults. Method: Longitudinal observational study comprising 711 patients aged >= 50 years consecutively admitted to a university hospital dedicated to COVID-19 severe cases, between March and May 2020. We reviewed electronic medical records to collect data on demographics, comorbidities, COVID-19 signs/symptoms, and laboratory findings on admission. We defined frailty using the Clinical Frailty Scale (CFS = 1-9; frail >= 5). We also documented in-hospital mortality. We used logistic regressions to explore associations between age, frailty, and COVID-19 signs/symptoms; and between typical symptoms (fever, cough, dyspnea) and mortality. Results: Participants had a mean age of 66 +/- 11 years, and 43% were female. Overall, 25% were frail, and 37% died. The most common COVID-19 presentations were dyspnea (79%), cough (74%), and fever (62%), but patients aged >= 65 years were less likely to have a co-occurrence of typical symptoms, both in the absence (OR = 0.56; 95% CI = 0.39-0.79) and in the presence of frailty (OR = 0.52; 95% CI = 0.34-0.81). In contrast, older age and frailty were associated with unspecific presentations, including functional decline, acute mental change, and hypotension. After adjusting for age, sex, and frailty, reporting fever was associated with lower odds of mortality (OR = 0.70; 95% CI = 0.50-0.97). Conclusions: Atypical COVID-19 presentations are common in frail and older hospitalized patients. Providers should be aware of unspecific disease manifestations during the management and follow-up of this population.

- COVID-19 is not over and age is not enough: Using frailty for prognostication in hospitalized patients(2021) ALIBERTI, Marlon Juliano Romero; SZLEJF, Claudia; AVELINO-SILVA, Vivian I.; SUEMOTO, Claudia Kimie; APOLINARIO, Daniel; DIAS, Murilo Bacchini; GARCEZ, Flavia Barreto; TRINDADE, Carolina B.; AMARAL, Jose Renato das Gracas; MELO, Leonardo Rabelo de; AGUIAR, Renata Cunha de; COELHO, Paulo Henrique Lazzaris; HOJAIJ, Naira Hossepian Salles de Lima; SARAIVA, Marcos Daniel; SILVA, Natalia Oliveira Trajano da; JACOB-FILHO, Wilson; AVELINO-SILVA, Thiago J.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.
