Software production by nurses for use in patient care

Objective: analyzing the scientific literature referring to strategies used for the production of software for the application by nurses in patient care through a literature review published between 1985 and 2013 and summarizing the findings. Method: an integrated review article search occurred online in English, Portuguese and Spanish, in databases LILACS, BDENF, MEDLINE, IBECS, Web of Science and SCOPUS, where the descriptors were applied individually and subsequently crossed, finally applied the filters language and period, limiting the search. Results: it was found that most software produced by nurses was directed to the educational area. There were found only seventeen studies on the topic in question, of which 52% had high impact strength. Conclusion: in this age of technology, this production may still be considered too little

Lactic-acid bacteria increase the survival of marine shrimp, Litopenaeus vannamei, after infection with Vibrio harveyi

Este trabalho avaliou a adição de duas cepas de bactérias lácticas (2 e B6) na sobrevivência, qualidade de pós-larva e na população de bactérias na larvicultura de Litopenaeus vannamei experimentalmente infectado por Vibrio harveyi. Mil e quinhentos náuplios foram distribuídos em tanques de 20 L com quatro repetições. A sobrevivência dos animais controle foi menor (21%) do que a dos alimentados com as cepas B6 (50%) e 2 (44%). Sobrevivência de misis após desafio com V. harveyi foi maior em B6 do que nos outros tratamentos. A população total de bactérias na água e nas larvas, bem como de Vibrio ssp. na água não foi diferente entre os tratamentos. Não houve diferença, também, entre a população de Vibrio ssp. em larvas do grupo controle (5,5±0,5 log UFC/mL) e larvas alimentadas com a cepa 2 (5,4±0,1 log UFC/mL). Camarões do grupo controle e alimentados com cepa 2 apresentaram maior população de bactérias do que os alimentados com cepa B6 (1,2±0,2 log UFC/mL). Foi comprovada a menor presença de bactérias entéricas com potencial de patogenicidade nos animais alimentados com a cepa B6, apresentando também comportamento mais ativo e menor número de necroses em relação ao controle e cepa 2.This study evaluated the survival, post-larvae quality, and the population of bacteria in Litopenaeus vannamei after the addition of two strains of lactic-acid bacteria (2 and B6) experimentally infected by Vibrio harveyi. Fifteen hundred nauplii were distributed in 20 L capacity tanks with four replicates. The survival of control animals was lower (21%) than that of animals fed with the strains B6 (50%) and 2 (44%). Total bacterial population in the water and larvae, as well as of the Vibrio ssp. in water was not different among the treatments. No difference was observed in the population of Vibrio ssp. between the control larvae (5.5±0.5 log UFC/mL) and that fed with strain 2 (5.4±0.1 log UFC/mL). Shrimp from control and fed with strain 2 showed significantly higher bacterial population than those fed with strain B6 (1.2±0.2 log UFC/mL). It was detected the lower load of Vibrio ssp. bacteria with potential of pathogenicity after feeding with strain B6.Moreover, these larvae showed more active behavior and low number of necrosis in relation to the control group and to that fed with strain 2

Chemical composition and in vitro antibacterial activity of essential oils from Murraya paniculata (L.) Jack (Rutaceae) ripe and unripe fruits against bacterial genera Mycobacterium and Streptococcus

This study aims to investigate chemical composition of essential oils from Murraya paniculata (L.) Jack (Rutaceae) ripe and unripe fruits and determine their in vitro antibacterial activity. Essential oils were extracted by hydrodistillation from Murraya paniculata (L.) Jack ripe and unripe fruits collected in the Cerrado, in Rio Verde, southwestern Goiás, Brazil. They were analyzed by gas chromatography with flame ionization detector (GC-FID) and by gas chromatography-mass spectrometry (GC-MS). Sesquiterpenes, which represent the most abundant class of compounds in oils, predominated in both ripe and unripe fruits. Major constituents of essential oils extracted from ripe fruits (RF-EO) were β-caryophyllene (21.3%), α-ylangene (13.3%), germacrene-D (10.9%) and α-zingiberene (9.7%) whereas the ones of unripe fruits (UF-EO) were sesquithujene (25.0%), α-zingiberene (18.2%), germacrene-D (13.1%) and α-copaene (12.7%). In vitro antibacterial activity of essential oils was evaluated in terms of its minimum inhibitory concentration (MIC) values by the broth microdilution method in 96-well microplates. Both essential oils under investigation showed moderate anti-streptococcal activity against the following bacteria: Streptococcus mutans, S. mitis, S. sanguinis, S. sobrinus and S. salivarius. MIC values ranged between 100 and 400 µg/mL. Regarding the antimycobacterial activity, essential oils from M. paniculata (L.) Jack unripe and ripe fruits were active against Mycobacterium kansasii (MIC = 250 µg/mL), moderately active against M. tuberculosis (MIC = 500 µg/mL) and inactive against M. avium (MIC = 2000 µg/mL). This study was pioneer in revealing similar chemical profiles of both essential oils extracted from Murraya paniculata (L.) Jack unripe and ripe fruits, besides describing their in vitro anti-streptococcal and antimycobacterial activities

Rotavirus and the emergence of new genotypes: a narrative review

Rotavirus infection, which is directly related to the population’s quality of life, can culminate in death, mainly of children. This review discusses the prevalence and distribution of rotavirus genotypes, focusing on the genotypic variation of the virus after the implementation of vaccines and the cross-infection between animal and human species. It was searched the published literature from January 2006 to July 2017 using the Web of Knowledge database and the search terms “rotavirus”, “genotype”, “prevalence post vaccine”, and “emerging genotypes”. It was observed that the predominant genotypes changed in all continents, and that some genotypes are still emerging. Two hypotheses for this global change are the genetic variability of the virus and the emergence of vaccine-resistant genotypes. In addition, the virus can easily infect several animal species other than humans, as evidenced by reports of cross-infection of strains, which have served as warning for the generation of new virus genotypes. Inter-sectoral actions that encompass not only the health sector, but also all the socio-economic sector including the government, researchers, teachers, health agents, and communities contribute to decrease health-related expenditures and reduce mortality caused by the rotavirus, thereby improving health indicators and promoting health around the world.Rotavirus infection, which is directly related to the population’s quality of life, can culminate in death, mainly of children.

Biologically-active compounds from Brazilian lichens and their affinity with ether

It can be obtained from lichens biologically-active extracts and pure substances, many of them of phenolic nature. They are usually obtained by using organic solvents, such as diethyl ether. In this paper the usefulness of ether for the obtainment of crude extracts and the subsequent purification of pure substances from Brazilian lichen is reviewed, as well as alternatives to their production through cells or thallus immobilization in bioreactors and their entrapment in inert matrix
