Mixed crude glycerin in laying hen diets: live performance and egg quality and fatty acid profile

This study evaluated the performance and the quality and fatty acid profile of eggs from laying hens fed diets containing mixed crude glycerin (MCG; 80% vegetable fat + 20% animal fat). A total of 240 39-week-old Hy-Line W36 laying hens were distributed according to a completely randomized experimental design into six treatments consisting of graded MCG dietary inclusion levels (0, 1.5, 3.0, 4.5, 6.0, and 7.5%), with five replicates of eight birds each. Feed intake linearly decreased (p<0.05) with increasing MCG inclusion levels. The percentages of myristic, palmitic, and &#945;-linolenic acids in the eggs linearly decreased as MCG dietary levels increased (p<0.05), while &#945;-linoleic acid, polyunsaturated fatty acids (PUFA) and &#969;-6/&#969;-3 ratio linearly increased. Excreta moisture linearly increased with increasing levels of MCG inclusion (p<0.05). MCG may be included in up to 7.5% in layer feeds without impairing performance or egg quality, but levels up to 5.54% reduce SFA egg content. However, the inclusion of MCG in layer diets increases &#969;-6/&#969;-3 ratio in the eggs

Percepção da equipe de enfermagem sobre humanização em unidade de tratamento intensivo neonatal e pediátrica

A humanização em saúde é uma das prioridades nas políticas de saúde no Brasil, implicando as atitudes dos usuários, trabalhadores e gestores dos serviços. Este estudo objetivou identificar a percepção da equipe de enfermagem sobre a humanização no cuidado em uma unidade de terapia intensiva neonatal e pediátrica. Trata-se de uma pesquisa exploratória, descritiva, com abordagem qualitativa. Participaram, do estudo, 11 integrantes da equipe de enfermagem da unidade deterapia intensiva neonatal e pediátrica de um hospital do sul do Brasil. A coleta de dados ocorreu por meio de entrevistas semiestruturadas, analisadas conforme referencial da análise de conteúdo temática. Emergiram três categorias temáticas: humanizar é ver o outro como um todo-acolher; o vínculo e a comunicação como práticas humanizadoras; e falta de ambiência como prática desumanizadora. Identificou-se que a compreensão da equipe de enfermagem sobre humanização pauta-se na própria ciência do cuidado de enfermagem, e não especificamente na Política Nacional de Humanização

In vitro sealing ability of white and gray mineral trioxide aggregate (MTA) and white Portland cement used as apical plugs

This study evaluated the sealing ability of apical plugs made of white and gray MTA-Angelus® and white Portland cement placed via the root canal and having different thicknesses (2, 5 and 7 mm). Ninety extracted human single-rooted teeth were instrumented using a size 40 K-file to standardize the foraminal opening by the stepback technique. The teeth were assigned to 3 groups (n=30), according to the material used for fabrication of the apical plugs: A = gray MTA; B = white MTA; C = white Portland cement. The groups were subdivided into groups of 10 teeth each according to the apical plug thickness (2, 5 and 7 mm). Marginal apical dye leakage was assessed using 0.2% Rhodamine B solution in which the specimens were immersed for 72 hours at 37ºC. The roots were sectioned longitudinally in a buccolingual direction for apical plug exposure, and digital photographs were taken and analyzed by Image Tool image-analysis software. Data were analyzed statistically by Kruskal-Wallis and Dunn's tests. Significance level was set at 5%. The least percent leakage was observed for 5- and 7-mm-thick plugs (p<0.05). No significant difference (p>0.05) was found between gray MTA and white Portland cement. Among the three materials analyzed, white MTA presented the highest marginal leakage (p<0.05). The findings of the present study showed that gray MTA and Portland cement had better sealing ability than white MTA when used as apical plugs. Dye leakage was smaller for 5- and 7-mm-thick plugs compared to 2-mm-thick plugs
