New insights into the distribution and conservation status of the Golden-White Tassel-Ear Marmoset Mico chrysoleucos (Primates, Callitrichidae)

Among the 13 Mico species recognized by the IUCN Red List of Threatened Species, six are listed as "Data Deficient". The geographic range of most of the Mico species has been estimated from only a few records. We report new localities and the geographic extension of Mico chrysoleucos. In addition, we confirmed the presence of the species in two distinct protected areas. We modeled the habitat suitability of M. chrysoleucos using the maximum entropy method and including new records obtained by the authors in the state of Amazonas, Brazil. From the total area of occurrence calculated for the species, 22.8% is covered by protected areas and indigenous lands. The annual mean deforestation rate estimated between 2000 and 2015 was 2.95%, and the total area deforested by 2015 was 3354 km2 or 8.6% of the total distribution limits of the species. The habitat lost between 2000 and 2015 was 3.2% (1131 km2 ) of the total potential distribution, while the habitat loss area legally protected was 31 km2, and the habitat loss in settlements was equal to 691 km2. Our results extend the geographic distribution of the species about 100 km farther south, with the Maracanã River being a possible geographic barrier for the species. The significantly low rate of habitat loss inside protected areas and indigenous land, when compared to unprotected areas, points out the importance of these areas to M. chrysoleucos conservation. The species is relatively wide-ranging, legally protected, and resilient to regional anthropic threats. However, the hydroelectric schemes and the improvement of the road system in southern Amazonia pose an imminent threat to the species

Neuropsychiatric symptoms of the elderly with Alzheimer's disease and the family caregivers' distress

ABSTRACT Objective: to analyze the relationship between the distress of the family caregiver and the presence of neuropsychiatric symptoms in elderly patients with Alzheimer's disease or mixed dementia. Method: a descriptive, cross-sectional study conducted in the Geriatric and Dementias Clinic of a general tertiary hospital, with 96 elderly people with Alzheimer's disease or mixed dementia and their family caregivers. Questionnaires to characterize the elderly and caregivers, and the Neuropsychiatric Inventory were used. Descriptive statistics and Pearson correlation test were performed. Results: 68.7% of the elderly were women, average age 80.8 years, 56.2% had Alzheimer's disease and 43.7%, mixed dementia. Among caregivers, 90.6% were women, average age 56, 70.8% took care of parents and 64.6% lived with the elderly. There was a strong (r = 0.82) and significant (p <0.01) correlation between the total score on the Neuropsychiatric Inventory and the total score on the Neuropsychiatric Inventory-Distress and strong (r = 0.80) and significant (p <0 01) correlation between the total score on the Neuropsychiatric Inventory Distress and the number of neuropsychiatric symptoms, i.e., the higher the number, frequency and severity of these symptoms in the elderly, the more intense is the caregiver distress. Conclusion: the presence of neuropsychiatric symptoms in the elderly was related to increased distress in caregivers

Capacidade funcional e uso de serviços de saúde por idosos da Região Metropolitana de Belo Horizonte, Minas Gerais, Brasil: um estudo de base populacional

O presente trabalho investigou a associação entre a capacidade funcional e utilização de serviços de saúde entre idosos residentes na Região Metropolitana de Belo Horizonte, Minas Gerais, Brasil. Participaram do estudo 1.624 idosos (≥ 60 anos) selecionados por meio de amostra probabilística. A variável dependente foi a utilização de serviços de saúde, baseada em três descritores: número de consultas médicas, consultas domiciliares e hospitalizações. A variável independente de interesse foi a capacidade funcional, medida pelo relato de dificuldade em realizar atividades instrumentais (AIVD) e básicas (ABVD) de vida diária. A primeira esteve associada apenas à hospitalização (RP = 1,62; IC95%: 1,16-2,26) e a segunda apresentou-se associada à hospitalização (RP = 1,73; IC95%: 1,24-2,42) e à consulta domiciliar (RP = 8,54; IC95%: 4,22-17,27). Os resultados mostraram maior utilização de serviços de saúde, sobretudo aqueles mais onerosos, entre idosos com incapacidade funcional, e que a dimensão funcional não tem sido balizadora da atuação dos serviços, ainda condicionada à presença de doenças
