    Institutionalized elderly have an increased risk of changes in nutritional status, therefore sensitive parameters are necessary for the identification of changes in nutritional status. The aim of this study was to evaluate parameters for analysis of the nutritional status of institutionalized elderly in a period of three months by means of biochemical and anthropometric measurements. Eighty one volunteers were selected, with 78 ± 10 years old and 53% female. Anthropometric data showed that the variables body mass index, weight, fat mass, and phase angle of the institutionalized elderly in three months decreased with significant difference between the assessments. Among all the biochemical and anthropometric measurements, body mass index, weight, fat mass, phase angle and blood fat were the indicators of nutritional assessment that identified early changes and nutritional risks of institutionalized elderly in three months. It is noteworthy that the early evaluation of nutritional indicators can prevent nutritional risk among elderly in living in rest homes. Idosos institucionalizados apresentam um risco aumentado de alteração do estado nutricional. Sendo assim, são necessários indicadores sensíveis para identificação da alteração do estado nutricional. O objetivo deste estudo é avaliar indicadores para análise do estado nutricional de idosos institucionalizados, em um período de três meses, por meio de exames bioquímicos e antropométricos. Foram selecionados 81 voluntários, com 78 ± 10 anos, sendo 53% do sexo feminino. Os dados antropométricos evidenciaram que as variáveisíndice de massa corporal, peso, massa gorda e ângulo de fase dos idosos institucionalizados diminuíram em três meses com diferença significativa no período. Dentre todos os exames bioquímicos e antropométricos, as variáveis índice de massa corporal, peso, massa gorda, ângulo de fase e lipidograma foram os indicadores da avaliação nutricional que identificaram alterações precoces e riscos nutricionais dos idosos institucionalizados no período de três meses. Vale ressaltar que indicadores nutricionais avaliados precocemente podem evitar os riscos nutricionais de idosos institucionalizados.

    Influence of agricultural extension activities on tick control among cattle on family dairy farms in the southeast Brazil

    ABSTRACT The aim of the present study was to evaluate the resistance of tick populations on 16 family farms that were members of the agricultural producers’ cooperative of the São Pedro region of the state of São Paulo (COOPAMSP). Bioassays were conducted on nine commercial products in 2018 and 2019. Their active agents were as follows: deltamethrin, amitraz, cypermethrin + chlorpyrifos + citronella, cypermethrin + chlorpyrifos + fenthion, cypermethrin + chlorpyrifos + piperonyl butoxide, dichlorvos + chlorpyrifos, cypermethrin, chlorfenvinphos + dichlorvos, and ivermectin. On some farms, a larval packet test (LPT) was also performed. Overall, four acaricides presented mean efficacy greater than 89%, among which two were associations of pyrethroids + organophosphates and two were associations of organophosphates + organophosphates. Deltamethrin, cypermethrin and ivermectin presented mean efficacy lower than 50%. In the bioassays using the LPT, all five farms showed resistance to diazinon, while only one farm presented resistance to cypermethrin. The results were handed over to each farmer with appropriate guidance for treatments. This study demonstrated that the important points to be implemented related directly to use control strategies, based on direct assistance for farmers and diagnosis of tick population sensitivities.
