“…The present study found prevalence of anaemia of 12.2% in the elderly studied. These findings are in line with other brazilian studies that involved elderly people enrolled in the FHU, developed by Buffon et al (2015), Barbosa et al (2006) and Sousa et al (2018), who reported rates between 8, 8% and 12.5%. Moreover, when com-pared to the 10.6% prevalence of anaemia founded by Le (2016) in the developed non-institutionalized civilian population of the United States, the value observed in most of the brazilian studies cited remains higher, which is reaffirmed by the fact that the US study only analyzes individuals over 65 years old, which would tend to raise the prevalence found.…”

Population growth is a worldwide phenomenon responsible for significant changes in the population pyramid. In this context, the increase in life expectancy has contributed significantly to the growth of the elderly population. Considering that this age group is associated with a decline in the functional reserve of multiple organic systems, a condition capable of causing dysfunctions and diseases in the elderly, the best clarification about the implications of aging becomes essential. The present research aimed to study the prevalence of ane-Prevalence of anaemia in a sample of elderly northeastern brazilians

“…The same pattern was observed in an American study 24 . Brazilian investigations with the elderly also found higher prevalence of anemia in the males compared to the femals 8,9,14 . The effect that men are more likely to have anemia in older age groups may be related to the reduction in testosterone production, which has a significant impact on lowering hemoglobin levels in the body 28 .…”

RESUMO: Objetivo: Verificar a prevalência de anemia em adultos e idosos brasileiros. Métodos: Foram utilizados dados provenientes de exames laboratoriais da Pesquisa Nacional de Saúde. Trata-se de um estudo transversal no qual foram incluídos 8.060 indivíduos com idades acima de 18 anos de todos os estados brasileiros. Foram estudados os seguintes indicadores obtidos por meio de eritrograma: dosagem de hemoglobina, volume corpuscular médio (VCM), hemoglobina corpuscular média (HCM) e red cell distribution width (RDW). Utilizaram-se as recomendações da Organização Mundial da Saúde, que consideram anemia o nível de hemoglobina menor que 13,0 g/dL para homens e menor que 12,0 g/dL para mulheres. As informações sociodemográficas foram obtidas por meio de entrevista. Resultados: A prevalência de anemia entre adultos e idosos brasileiros foi de 9,9%. Maiores prevalências de anemia e casos mais graves foram encontrados entre mulheres, idosos, pessoas de baixa escolaridade e de cor de pele preta e residentes das regiões Norte e Nordeste. Anemia normocítica e normocrômica foi o tipo mais comum (56,0%). Conclusão: A prevalência de anemia está de acordo com a literatura. Destaca-se que maiores prevalências foram observadas nas populações mais desfavorecidas e entre os idosos. Considerando o crescimento da população acima de 60 anos no país, intervenções para tratar e prevenir a anemia em adultos e idosos se fazem necessárias na rede de serviços de saúde.

“…The level of hemoglobin in the serum was significantly correlated with cognitive impairment. Additionally, studies have demonstrated that EPO can have neuroprotective effects ( Fan et al, 2012 ), the production of EPO can be stimulated by anemic hypoxia in the brain, and anemia is an independent risk factor of cognitive decline ( Sousa et al, 2018 ).…”

It has long been believed that kidney function is linked to brain activity. Clinical studies demonstrate that patients with chronic kidney disease (CKD) are more prone to cognitive impairment and Alzheimer’s disease (AD), and the degree of cognitive impairment is closely related to CKD progression and renal failure. Moreover, the fact that cognitive function in CKD patients is significantly improved after successful kidney transplantation reveals a linkage between CKD and AD. However, the mechanisms behind this linkage are unclear. The physiological function of the kidney is to maintain the stability of the internal environment, including the cerebrovascular circulation, whereas abnormal kidney function often leads to ischemia and hypoxia. Many CKD patients experience chronic hypoxia, and many urinary toxins accumulate after renal function is impaired. In this mini review, we will propose a novel perspective on the association between AD and CKD and the connection between the kidney and brain.
