Síndrome de risco cognitivo motor em pessoas idosas de um serviço de saúde do Distrito Federal: estudo transversal / Motoric cognitive risk syndrome in older adults at a health service in the Distrito Federal: a cross-sectional study

Resumo Objetivo Verificar a prevalência da síndrome de risco cognitivo motor (SRCM) em pessoas idosas do Distrito Federal (DF), Brasil, que frequentaram os serviços de saúde de uma unidade de referência em Geriatria e Gerontologia, comparar os grupos de idosos com e sem a síndrome e investigar os possíveis fatores associados ao desenvolvimento dessa síndrome. Método Trata-se de estudo observacional transversal analítico, desenvolvido com idosos (idade ≥60 anos) com marcha independente e sem alterações cognitivas graves, que possuíam registro de dados sociodemográficos, avaliação cognitiva, capacidade funcional e velocidade de marcha em prontuários datados de 2017 a 2019. A análise dos dados foi expressa em média e desvio-padrão, frequência e percentual, e em odds ratios (OR) com intervalos de confiança de 95%. As comparações entre os grupos com e sem a SRCM foram feitas por meio dos testes: qui-quadrado, U de Mann-Whitney e t de Student. Resultados Não houve diferenças significativas na comparação das variáveis entre os grupos. A prevalência da SRCM na população estudada foi de 24%. Nenhum dos fatores analisados demonstrou associação com a presença da síndrome. Conclusão A prevalência da SRCM na amostra foi de 24% e mostrou-se mais alta na população do DF quando comparada as populações estudadas em outros países. Não houve diferenças entre os grupos de idosos com e sem a síndrome, e os fatores associados não foram encontrados. O rastreio da síndrome é de extrema relevância, pois a partir desses achados pode-se desenvolver mecanismos para a prevenção de demência em idosos.

Abstract Objective To verify the prevalence of the motoric cognitive risk syndrome (MCR) in older adults from the Distrito Federal (DF), Brazil, who attended the health services of a reference unit in Geriatrics and Gerontology, compare groups of older adults with and without the syndrome and investigate the possible associated factors for the development of this syndrome. Method This is an observational cross-sectional analytical study, developed with older adults (age ≥ 60 years) with independent gait and without severe cognitive dysfunctions, who had a record of sociodemographic data, cognitive assessment, functional capacity and gait speed in medical records dated 2017 to 2019. Data analysis was expressed as mean and standard deviation, frequency and percentage, and odds ratios (OR) with 95% confidence intervals. Comparisons between groups with and without MCR were made using the chi-square, U Mann Whitney and t-student tests. Results There were no significant differences in the comparison of variables between groups. The prevalence of MCR in the studied population was 24%. None of the factors analyzed showed an association with the presence of the syndrome. Conclusion The prevalence of MCR in the sample was 24% and was shown to be higher in the population of the DF when compared to the populations studied in other countries. There were no differences between the groups of older adults with and without the syndrome, and the associated factors were not found. Screening for the syndrome is hugely relevant, as, from these findings, mechanisms can be developed to prevent dementia in old people.

Acompanhamento do envelhecimento humano em centro de convivência / Monitoring human aging in a care center

Resumo Este artigo discute o papel dos centros de convivência no acompanhamento do envelhecimento humano. A partir de revisão bibliográfica, exploramos história, experiências e possibilidades dos centros de convivência. Percebemos "senicultura" como cultivo, mas também controle social do idoso. Evitando o controle, a rede de cuidados pode nortear suas ações pela autoavaliação do idoso e sua percepção de qualidade de vida. Enfatizamos a importância dos vínculos, a relação cuidador-cuidado como espaço de transformação da maneira de lidar com o envelhecimento. Propomos centros de cuidado como estratégia para evitar o isolamento dos idosos e oportunizar a convivência intergeracional.

Abstract This paper discusses the role of senior centers in human aging. Through literature review we explored history, experiences and possibilities in senior centers. We perceive "seniculture" as cultivation, but also social control of the elderly. Avoiding control, the network care can guide their actions by self-assessment of the elderly and their perception regarding the quality of life. We emphasize the importance of bonds, the caregiver-cared relationship as a space of transformation in the way of dealing with aging. We also propose care center strategies to provides opportunities for intergenerational relations and avoid age-segregation.

Perioperative nursing of middle-aged and elderly patients with lumbar spinal stenosis and degenerative lumbar scoliosis / 现代临床护理

Objective To summarize the perioperative experience of nursing the middle-aged and elderly patients of lumbar spinal stenosis and degenerative lumbar scoliosis treated with posterior or transforaminal lumbar interbody fusion. Methods Posterior or transforaminal lumbar interbody fusion was performed in 69 middle-aged and elderly patients with lumbar spinal stenosis and degenerative lumbar scoliosis. Nursing measures included evaluation and treatment of complications, preoperative guidance for surgical body position, and postoperative close monitoring, treatment of complications and functional exercises. Results The operation on all the 69 patients was smooth, with surgical time ranged from 3 to 7 hours and bleeding volume between 300~750 mL. Postoperatively, 9 patients suffered from CSF leaks, 3 ones had a screw loose by imageology, 2 did from pneumonia, 2 did from DVT, and 3 did from depression. After clinical management and nursing, all the patients were cured and discharged. Conclusions Meticulous clinical treatment and nursing of preoperative complications and instructions on body position are the foundation for successful surgeries. Postoperatively, close monitoring, management of the complications and the instruction on functional exercises are guarantees for the successful surgeries.

O envelhecimento do pâncreas endócrino: fisiopatologia de diabetes mellitus tipo 2 e a caracterização da incretinopatia com início na senectude / The aging of endocrine pancreas: physiopathology of diabetes mellitus type 2 and characterization of incretinpathy starting on senescence

Objetivo: Estimar o impacto do envelhecimento e do diabetes na sensibilidade à insulina, função da célula beta, adipocitocinas e produção de incretina Métodos: Foram realizados clamps hiperglicêmicos, testes de arginina e testes de refeição padrão em 50 pacientes não obesos para medir a sensibilidade à insulina e secreção de insulina, assim como os níveis plasmáticos do glucagon, GLP-1 e GIP. Os pacientes com diabetes e do grupo controle saudáveis foram divididos nos seguintes grupos: meia idade com diabetes tipo 2 (MI-DM2), idosos com diabetes tipo 2 (I-DM2), meia idade ou idosos com tolerância normal à glicose (MI-TNG, I-TNG). Resultados: A sensibilidade à insulina (SI), determinada pelo modelo de avaliação da homeostase, taxa de infusão de glicose e pela sensibilidade à insulina a glicose oral, foi reduzida no grupo de idosos e nos grupos com DM2, comparados com o grupo de meia idade com tolerância normal à glicose, mas foi similar no grupo MI-DM2 e grupo I-DM2. O índice insulinogênico, a primeira e segunda fase de secreção de insulina e o índice de disposição, com exceção da resposta da insulina à arginina, foram reduzidos com o envelhecimento e nos grupos com DM2. A produção pós-prandial média de glucagon no tempo total de 0 - 180 minutos foram maiores no grupo de DM2 comparado ao grupo de TNG, sendo que na primeira hora da produção de glugagon o grupo de I-DM2 apresentou uma média mais elevado em relação ao grupo de MI-DM2. Embora a produção de GLP-1 tenha sido reduzida no grupo I-DM2, nenhuma diferença entre os grupos foi observada em relação à produção de GIP. Conclusão: O diabetes e o envelhecimento desencadearam uma redução da sensibilidade à insulina em pacientes não obesos. A produção de insulina foi reduzida com o envelhecimento e exacerbada pela condição do diabetes. As deficiências associadas ao envelhecimento se sobrepõe a fisiopatologia do diabetes, particularmente relacionada à produção de GLP-1...

Objective: To estimate the impact of aging and diabetes on insulin sensitivity, beta-cell function, adipocytokines, and incretin production. Methods: Hyperglycemic clamps, arginine tests and meal tolerance tests were performed in 50 non-obese subjects to measure insulin sensitivity (IS) and insulin secretion as well as plasma levels of glucagon, GLP-1 and GIP. Patients with diabetes and healthy control subjects were divided into the following groups: middle-aged type 2 diabetes (MA-DM), elderly Type 2 diabetes (E-DM) and middle-aged or elderly subjects with normal glucose tolerance (MA-NGT or E-NGT). Results: IS (insulin sensitivity), as determined by the homeostasis model assessment glucose infusion rate and oral glucose insulin sensitivity, was reduced in the aged and DM groups compared with MA-NGT, but similar in MA-DM and E-DM groups. Insulinogenic index, first and second phase of insulin secretion and the disposition indices, except insulin response to arginine, were reduced in the elderly and DM groups. The average postprandial glucagon production on the interval of 0-180 min was higher in DM groups compared to NGT groups, furthermore noticed that in the first hour of glucagon secretion, group E-DM had a higher average value compared to group MA-DM. Whereas the GLP-1 production was reduced in A-DM, no differences between groups were observed in GIP production. Conclusions: In non-obese subjects, diabetes and aging impair insulin sensitivity. Insulin production is reduced by aging, and diabetes exacerbates this condition. Aging associated defects superimposed diabetic physiopathology, particularly regarding GLP-1 production. On the other hand, the glucose-independent secretion of insulin was preserved. The knowledge of the complex relationship between aging and diabetes could support the development of physiopathological and pharmacological based therapies.
