A importância da ambiencia no serviço de assistência ao parto: um estudo reflexivo / The importance of the environment in the labor assistance service: a reflective study

A ambiência é um tema extremamente relevante para a consolidação do modelo humanizado de assistência ao parto e nascimento. Considerando que a adequação da ambiência hospitalar proposta pela Política Nacional de Humanização é uma tendência no Brasil, reforçada pela RDC 36/2008 e recentemente criação das Redes Cegonhas em todo o País, objetivou-se refletir sobre a ambiência na assistência ao parto e nascimento, orientando boas práticas de humanização no atendimento a parturiente. Foi realizado um estudo teórico-reflexivo, construído com base na leitura crítica de estudos científicos atuais, que referenciam os benefícios da ambiência para o binômio, baseado em práticas humanizadas recomendadas pelo Ministério da Saúde e evidências cientificas. Fatores estruturais, assistência ao parto normal realizado por enfermeiras obstétricas e a presença de acompanhante foram citados como fortalecedores da qualificação da ambiência. Dessa forma, deveria haver mais investimentos dos gestores e esforços dos órgãos competentes nas instituições que prestam assistência a parturiente para tentar garantir que as mulheres possam vivenciar, de forma humanizada como recomenda o Ministério da Saúde, um dos momentos mais importantes de suas vidas: o nascimento de um filho

β-Glucosidase activity and antimicrobial properties of potentially probiotic autochthonous lactic cultures

Background The demand for lactic acid bacteria products, especially probiotics, has increased. Bacteria that increase polyphenol bioavailability and act as bio preservatives are sought after. This study aims to identify autochthonous lactic acid cultures from EMBRAPA that demonstrate β-glucosidase activity and inhibitory effect on microbial sanitary indicators. Methods Cell-free extracts were obtained by sonicating every 5 s for 40 min. The extracts were mixed with cellobiose and incubated at 50 °C. The reaction was stopped by immersing the tubes in boiling water. The GOD-POD reagent was added for spectrophotometer readings. Antimicrobial activity was tested against reference strains using the agar well diffusion method. Lactic cultures in MRS broth were added to 0.9 cm wells and incubated. The diameter of the inhibition zones was measured to determine the extension of inhibition. Results Only L. rhamnosus EM1107 displayed extracellular β-glucosidase activity, while all autochthonous strains except L. plantarum CNPC020 demonstrated intracellular activity for this enzyme. L. plantarum CNPC003 had the highest values. On the other hand, L. plantarum CNPC020, similarly to L. mucosae CNPC007, exhibited notable inhibition against sanitary indicators. These two strains significantly differed from the other five autochthonous cultures regarding S. enterica serovar Typhimurium ATCC 14028 inhibition (P 0.05). Therefore, it is advisable to consider these cultures separately for different technological purposes, such as phenolics metabolism or bio preservative activity. This will facilitate appropriate selection based on each specific property required for the intended product development

Consumo voluntário e digestibilidade de fenos triturados de gramíneas tropicais em caprinos Intake and apparent digestibility of chopped grass hays fed to goats

Objetivou-se determinar o consumo voluntário e a digestibilidade dos nutrientes de fenos triturados de milheto, sorgo sudanense, capim-elefante e cultivares de sorgo forrageiro SF-25 e IPA-467-4-2 em caprinos. Utilizaram-se 25 animais (18 meses de idade e 19,5 kg de PV inicial) distribuídos em um delineamento em blocos completos casualizados, com cinco tratamentos e cinco repetições. Os consumos de MS (CMS) e MO (CMO), quando expressos em porcentagem de peso vivo (%PV), não foram influenciados pelos tratamentos. O CMS representou, respectivamente, 2,41; 2,33; 2,25; 1,82 e 1,85% do PV dos caprinos. Os consumos voluntários de PB (%PV) evidenciaram diferenças significativas para os fenos de milheto e sorgo sudanense, que foram superiores aos de capim-elefante e aos dos sorgos SF-25 e IPA-467-4-2. Os consumos de FDN não diferiram entre os fenos e variaram de 236,14 a 322,10 g/dia, representando 1,25 a 1,61% do PV dos caprinos. A digestibilidade aparente da MS dos fenos não sofreu influência significativa e variou de 49,87 a 55,90%. Para a digestibilidade da PB (DPB), não foram constatadas diferenças significativas entre os fenos de milheto, sorgo sudanense, capim-elefante e sorgo SF-25. A digestibilidade da FDN (DFDN), no entanto, apresentou variação significativa entre os fenos do milheto (64,44%) e sorgo IPA-467-4-2 (54,72%). Os valores de digestibilidade, indicativos de qualidade, dos fenos triturados das cinco gramíneas foram aproximados e as diferenças requerem a realização de ensaios de desempenho para suas comprovações.<br>The objective of this trial was to investigate intake and apparent digestibility of nutrients on goats fed one of the following chopped grass hays: pearl millet (PMH), sudangrass (SH), elephantgrass (EH) or two cultivars of forage sorghum (FSH1 and FSH2). Twenty-five goats averaging 18 months of age and 19.5 kg of body weight were assigned to a completely randomized block design with five treatments and five replicates. DM intake (DMI), expressed as percentage of body weight (% BW), did not differ and averaged 2.41, 2.33, 2.25, 1.82, and 1.85%, respectively, for PMH, SH, EH, FSH1, and FSH2. The same was observed for the intakes of OM and NDF. However, CP intake as % BW was greater on goats fed PMH and SH than on those fed EH, FSH1, and FSH2. No significant differences were observed for the apparent total tract digestibility of DM that varied from 49.87 to 55.90% across hays. CP digestibility was lowest on FSH2, intermediate on SH and FSH1, and greatest on PMH and EH while that of NDF differed significantly only by comparing PMH (64.44%) with FSH2 (54.72%). It can be concluded that the overall nutritional quality of all five hays were similar and further research is required to verify potential differences in animal performance among these forage sources

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
