Pathogen disgust sensitivity protects against infection in a high pathogen environment.

Disgust is hypothesized to be an evolved emotion that functions to regulate the avoidance of pathogen-related stimuli and behaviors. Individuals with higher pathogen disgust sensitivity (PDS) are predicted to be exposed to and thus infected by fewer pathogens, though no studies have tested this directly. Furthermore, PDS is hypothesized to be locally calibrated to the types of pathogens normally encountered and the fitness-related costs and benefits of infection and avoidance. Market integration (the degree of production for and consumption from market-based economies) influences the relative costs/benefits of pathogen exposure and avoidance through sanitation, hygiene, and lifestyle changes, and is thus predicted to affect PDS. Here, we examine the function of PDS in disease avoidance, its environmental calibration, and its socioecological variation by examining associations among PDS, market-related lifestyle factors, and measures of bacterial, viral, and macroparasitic infection at the individual, household, and community levels. Data were collected among 75 participants (ages 5 to 59 y) from 28 households in three Ecuadorian Shuar communities characterized by subsistence-based lifestyles and high pathogen burden, but experiencing rapid market integration. As predicted, we found strong negative associations between PDS and biomarkers of immune response to viral/bacterial infection, and weaker associations between PDS and measures of macroparasite infection, apparently mediated by market integration-related differences. We provide support for the previously untested hypothesis that PDS is negatively associated with infection, and document variation in PDS indicative of calibration to local socioeconomic conditions. More broadly, findings highlight the importance of evolved psychological mechanisms in human health outcomes.

Contribution of structured therapeutic play in a nursing care model for hospitalised children. / Contribuição do brinquedo terapêutico estruturado em um modelo de cuidado de enfermagem para crianças hospitalizadas.

Objective To analyse how therapeutic play structured in a nursing care model contributes to the care of hospitalised children. Method This is a qualitative study based on convergent care research (CCR). Seven children participated in the study. Data were collected in September and October of 2014 by means of interviews with open-end questions and participant observation of therapeutic and dramatic play sessions and/or instructional play sessions based on the stages "Welcoming/Playing/Concluding" of the nursing model Care with Play. Data were analysed according to the analysis and interpretation stages of the CCR. Results The following three categories emerged: Meanings attributed by the child to hospitalisation and its influence on nursing care; Perception of the therapeutic procedures through therapeutic play, and Importance of the family in care. Final considerations It is concluded that the application of therapeutic play structured in the care model contributes to systematic and specialised nursing care.

RESUMO Objetivo Analisar como o Brinquedo Terapêutico estruturado em um Modelo de Cuidado de Enfermagem contribui no cuidado à criança hospitalizada. Método Trata-se de uma Pesquisa Convergente Assistencial (PCA), de abordagem qualitativa. Participaram do estudo sete crianças. A coleta de dados foi realizada entre setembro e outubro de 2014, por meio de entrevista aberta e de observação participante de sessões de BT dramático e/ou instrucional através das etapas “Acolhendo/Brincando/Finalizando” do Modelo de Cuidado de Enfermagem Cuidar Brincando. Os dados foram analisados de acordo com as fases de análise e interpretação da PCA. Resultados Três categorias: Significados atribuídos pela criança à hospitalização e sua influência no cuidado de enfermagem, Percepção quanto aos procedimentos terapêuticos por meio do brinquedo terapêutico e Importância da inserção da família no cuidado. Considerações finais Conclui-se que aplicar o BT estruturado em um Modelo de Cuidado pode contribuir para um cuidado de enfermagem sistematizado e especializado.

Problems of early infancy, formula changes, and mothers' beliefs about their infants.

Problems of early infancy are sometimes managed by changing an infant's formula from a cow milk formula to a soy protein or casein hydrolysate formula ("special formulas"). This study was designed to determine the frequency of formula changes, mothers' reports of problems that lead to such a change, and mothers' beliefs about the causes of these problems. Mothers of 189 breast-feeding (BF) and 184 formula-feeding (FF) infants were enrolled postpartum. Follow-up data were obtained by telephone interviews at 4 months. After starting a cow milk formula, 11% of the BF and 25% of the FF infants were given special formulas. Mothers frequently reported problems related to feeding, bowel movements, and crying behavior; 32% of infants with such problems were given special formulas. Excessive crying and colic were the most common problems leading to a formula change. When a formula was changed, mothers more frequently believed that the cause of the problem was intrinsic to the child (P less than 0.001) and that their infant had had a "disease or illness" (P less than 0.001). When formula changes occurred, 26% of mothers believed that their infants were allergic to cow milk. These beliefs may affect a mother's perceptions of her child's vulnerability.
