ABSTRACT

ABSTRACT Objective: The fibroblast growth factor 23 (FGF23) has been related to biological aging, but data in elderly individuals are scant. We determined the profile of serum FGF23 levels in a population of very-old individuals and studied their correlations with parameters of bone metabolism and health markers, as functional performance. Materials and methods: This cross-sectional study was performed on 182 community dwellers aged ≥ 80 years. Serum levels of FGF23, PTH, calcium, albumin, phosphorus, creatinine, bone markers, and bone mineral density data were analyzed. Physical performance was evaluated with the stationary march (Step), Flamingo, and functional reach tests, along with questionnaires to assess falls and fractures in the previous year, energy expenditure (MET), and the Charlson index (CI). Physical activity was evaluated with the International Physical Activity Questionnaire (IPAQ). Results: Most participants (75%) had FGF23 levels between 30-120 RU/mL (range: 6.0-3,170.0 RU/mL). FGF23 levels correlated with estimated glomerular filtration rate (eGFR; r = -0.335; p = 0.001) and PTH (r = 0.318; p < 0.0001). Individuals with FGF23 in the highest tertile had more falls in the previous year (p = 0.032), worse performance in the Flamingo (p = 0.009) and Step (p < 0.001) tests, worse CI (p = 0.009) and a trend toward sedentary lifestyle (p = 0.056). On multiple regression, FGF23 tertiles remained significant, independently of eGFR, for falls in the previous year, performance in the Flamingo and stationary march tests, lean mass index, and IPAQ classification. Conclusion: In a population of very elderly individuals, FGF23 levels were inversely associated with neuromuscular and functional performances. Higher concentrations were related to more falls, lower muscle strength and aerobic capacity, and poorer balance, regardless of renal function, suggesting a potentially deleterious role of high FGF23 concentrations in musculoskeletal health.

ABSTRACT

Abstract Introduction: In the last decades, there was an expressive increase in the number of elderly patients with chronic kidney disease starting hemodialysis. Thus, our goal was to evaluate the profile of the elderly in chronic hemodialysis and to compare the cognition and quality of life of the younger elderly with those of the very elderly. Methods: Patients on hemodialysis for at least 3 months, who were 65 years of age or older when they started dialysis were invited to participate, and stratified according to age (under or over 80 years). The participants answered a clinical-epidemiological questionnaire and underwent cognitive tests (Mini Mental State Exam [MMSE], clock drawing test [CDT] and verbal fluency test [VFT]) and a quality of life assessment 36- Item Short Form Health Survey). Results: Of the 125 eligible patients, 124 agreed to participate. The mean age was 76 ± 6 years (28% ≥ 80 years), 56% were men and 55% had ≥ 8 years of schooling. Depression was suggested in 38%. The prevalence of cognitive deficit was 38%, 70% and 30%, by MEEM, CDT and VFT, respectively. The prevalence of any deficit was higher among the very elderly (94% vs. 72%, p = 0.007). Quality of life scores were similar between the two age groups, except for the functional capacity domain, worse in the group with ≥ 80 years (p = 0.033). Conclusion: Elderly patients on chronic hemodialysis have a high prevalence of cognitive deficits, especially the very elderly, but this group does not have a worse quality of life, except for functional capacity.


Resumo Introdução: Nas últimas décadas, houve um aumento expressivo no número de pacientes idosos com doença renal crônica iniciando hemodiálise. Assim, nosso objetivo foi avaliar o perfil de idosos em hemodiálise crônica e comparar a cognição e a qualidade de vida dos idosos com as de muito idosos. Métodos: Pacientes em hemodiálise havia pelo menos 3 meses, que tinham 65 anos ou mais quando começaram o tratamento dialítico foram convidados a participar, e estratificados de acordo com a idade (menores ou maiores de 80 anos). Os participantes responderam a um questionário clinico-epidemiológico e foram submetidos a testes cognitivos (miniexame do estado mental [MEEM], teste do relógio [TDR] e teste de fluência verbal [TFV]) e a uma avaliação de qualidade de vida 36-Item Short Form Health Survey). Resultados: Dos 125 pacientes elegíveis, 124 concordaram em participar. A idade média foi de 76 ± 6 anos (28% ≥ 80 anos), 56% eram homens e 55% tinham ≥ 8 anos de escolaridade. Depressão foi sugerida em 38%. A prevalência de déficit cognitivo foi 38%, 70% e 30%, pelo MEEM, TDR e TFV, respectivamente. A prevalência de qualquer déficit foi maior entre os muito idosos (94% vs. 72%, p = 0,007). Os escores de qualidade de vida foram semelhantes entre os dois grupos etários, exceto pelo domínio da capacidade funcional, pior no grupo com ≥ 80 anos (p = 0.033). Conclusão: Os pacientes idosos em hemodiálise crônica apresentam elevada prevalência de déficit cognitivo, especialmente os muito idosos, mas esse grupo não possui pior qualidade de vida, exceto pelo aspecto da capacidade funcional.

ABSTRACT

O envelhecimento é um fenômeno mundial e também brasileiro. Dentro da população de idosos, o grupo dos mais velhos cresce expressivamente. Idosos mais velhos fazem parte de uma população mais fragilizada por sofrerem maior impacto dos reflexos sociais, interferindo diretamente no processo saúde doença e necessitando de maior aporte de investimentos em políticas públicas. Objetiva-se descrever as percepções sobre vida e a velhice a partir das falas dos idosos centenários. Trata-se de um estudo descritivo e qualitativo que envolveu nove idosos residentes no município de Passo Fundo RS, com idade igual ou superior a 100 anos e cognição preservada. Na entrevista para coleta de dados, utilizou-se roteiro contendo questões semi estruturadas sobre aspectos sociodemográficos e questões abertas sobre as percepções de sua vivência centenária e memórias de vida. A vida aos 100 anos, no que confere a autopercepção de saúde, é entendida por alguns dos participantes como sendo boa, mesmo frente às adversidades, pois se locomovem com auxílio de dispositivo e mantém cuidados com a dieta. Para outros a vida é vista com reservas, pois percebem suas limitações no plano sensorial, como enxergar e escutar muito pouco, necessitando de auxílio para quase todas as atividades. Para alguns idosos a velhice significa tempo de reverência a Deus e à vida; tempo de perdão e de agradecimento; tempo de contemplação às amizades e à família e tempo de ir embora. Já os idosos com limitações severas e funcionalidade comprometida atribuem à velhice o significado de infortúnio, por outro lado, também a observam como tempo de graça e felicidade pelas experiências que a vida ofertou.


Ageing is a global phenomenon and also Brazilian. Within the elderly population, the older group grows significantly. Older seniors are part of a weakened population by suffering the greatest impact of the social reflexes, interfering directly in the health-sickness process and requiring more inflow of public policy investments. It aims to describe the perceptions about life and old age from the speech of centennial elders. A descriptive and qualitative study that involved nine elderly residents in the city of Passo Fundo-RS, with age equal or over 100 years and preserved cognition. In the collecting data with interview, it was used an instrument containing semi-structured questions about social demographic aspects and open ended questions about the perceptions of their centennial experiences and life memories. Life in the 100 years, which gives the perception of health, is understood by some respondents as being good, even in the face of adversity, they move themselves with the aid of a device and maintains care with diet, for others it is seen with reservations because they realize their limitations in sensory plan such as seeing and listen too little, needing help for all activities. The meaning of old age: time of reverence to God and life; time of forgiveness and thanksgiving; time of contemplation of the friendships and family and time to go away. Seniors with severe limitations and compromised functionality assign meaning to old age as misfortune, on the other hand is also seen as a time of grace and happiness by the experiences that life has offered.

ABSTRACT

A capacidade de desempenho em atividades da vida diária permite a pessoa idosa cuidar-se e responder por si no âmbito doméstico; porém, na velhice, o declínio físico representa um risco severo a sua independência. Este estudo objetivou descrever as condições de funcionalidade de um grupo de idosos centenários no município de Passo Fundo (RS). Participaram nove idosos com idade entre 100 e 104; para coleta dos dados, utilizou-se uma entrevista semi-estruturada e aplicação do índex de Katz; os dados foram analisados qualitativamente. Os resultados apontam que o desempenho da função “banho” ainda é a mais comprometida. As funções “vestir-se e banheiro” estão, em sua maioria, no grupo Independentes. Os centenários deste estudo necessitam menos auxílio em funções como a de “transferência, continência e alimentar-se”, o que demonstra maior independência diante de algumas funções importantes no dia a dia do idoso. Os homens deste estudo demonstram maior independência, se comparados às mulheres.


The capacity of performance in activities of daily living care allows the elderly up and answer for themselves domestically, but the physical decline in old age represents a severe risk to their independence. This study aimed to describe the conditions of functionality of a group of elderly centenarians in Passo Fundo (RS). Participated in nine subjects aged between 100 and 104, for data collection used a semi-structured interview and application of the Katz index, the data were analyzed qualitatively. The results show that the performance of the function "bath" is still the most compromised. The functions "dressing and bathroom" are mostly in the independent group. The centenarians in this study need less aid in functions such as "transfer, continence and feeding," which demonstrate greater independence ahead to some important functions in everyday life of the elderly. The men in this study, demonstrate more independence compared to women.
