On the Design of Aqueous Emulsions of Colophony Resin.

Companies regularly face market pressure to develop products faster but they also need to simultaneously incorporate technological constraints, sustainability trends, and customer requirements into their designs, which requires the use of systematic procedures. Firms that exploit natural resources and convert them into high-value products are among them. However, the literature on the application of such systematic approaches to products of this type remains scarce, as they often requrire extensive experimental plans involving the testing and optimization of multiple formulations. Here, we propose a systematic approach to the design of pine-resin-in-water emulsions, which can be used to fabricate pressure-sensitive adhesives. The strategy is customer-centric in the sense that the customers' specifications are integrated into the decision-making tool used to assess the quality of the formulations obtained through experiments. This tool uses loss functions to assess satisfaction with individual quality characteristics and multi-attribute decision-making methods to integrate them into an overall quality metric. Our framework is aligned with industrial practices and consists of three sequential stages: (i) screening of primary factors; (ii) optimization of secondary factors; and (iii) assessment of the experimental repeatability of the formulations. In each of these stages, the decision-making tool is used to "drive" the process of finding the optimal formulation.

First record of the Lesser Snouted Treefrog Scinax nasicus (Cope, 1862) in Brazilian coast and new species records for the state of Rio Grande do Sul / Primeiro registro da perereca-de-banheiro Scinax nasicus (Cope, 1862) na costa do Brasil e novos registros para o estado do Rio Grande do Sul

Abstract Herein, we provide new occurrence records of Scinax nasicus (Cope, 1862) for the state of Rio Grande do Sul, Southern Brazil. All new records here provide are located on Southern half of the state. Besides this, we provide the first record for species in Brazilian coastal zone. Those records improve considerably our knowledge regarding species distribution in Southern Brazil.

Resumo Aqui, nós fornecemos novos registros de ocorrência de Scinax nasicus (Cope, 1862) para o estado do Rio Grande do Sul, Sul do Brasil. Todos os novos registros aqui fornecidos estão localizados na metade sul do estado. Além disso, nós fornecemos o primeiro registro para a espécie na zona costeira brasileira. Esses registros melhoram consideravelmente o nosso conhecimento sobre a distribuição da espécie no Sul do Brasil.

Etiological profile of early neonatal bacterial sepsis by multiplex qPCR.

INTRODUCTION: Given the major impact in terms of morbidity and mortality that episodes of early neonatal sepsis (ENS) have on both newborns and health systems, this study aimed to identify the etiological profile of early neonatal bacterial sepsis by a multiplex quantitative real-time polymerase chain reaction (qPCR). METHODOLOGY: Blood samples from newborns diagnosed with clinical ENS and hospitalized in neonatal intensive care units (NICUs) were collected and analyzed using the multiplex qPCR method to detect Streptococcus agalactiae, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter sp., Serratia sp., and Staphylococcus aureus. A universal primer was used in the analysis. RESULTS: A total of 150 neonates with clinical sepsis and 10 newborns as healthy controls were included in the study. The group with clinical sepsis was 100% positive for the presence of bacterial genomic DNA through the universal primer. The control group showed negativity by qPCR. The multiplex qPCR analysis showed that 76% of the samples were positive for Escherichia coli, 34% for Staphylococcus aureus, 13.3% for Streptococcus agalactiae, 7.3% for Pseudomonas aeruginosa, and 0.7% for Enterobacter sp. and Serratia sp. Multiplex qPCR of patients with clinical sepsis matched with 8.1% of the blood samples that tested positive by the microbiological method. CONCLUSIONS: Rapid and sensitive detection of the pathogens causing ENS by this new multi-target approach based on multiplex qPCR could potentially excel compared to microbiological methods, with the simple objective of facilitating the progression to a more rapid and specific antimicrobial therapy, avoiding the abuse of antibiotics in NICUs.

Video-thoracoscopy closure of coronary artery fistula: case report.

The coronary artery fistulas (FAC) are rare and often found occasionally. The conventional treatment can be made by surgical closure with median thoracotomy or with embolization by catheterization. We describe an innovative technique to ligature of FAC, on a full endoscopy. Women, 45 years with symptomatic fistula between coronary artery anterior descending and trunk artery pulmonary, which took thoracoscopy left, pericardiotomy and ligation of fistula with metal clip without thoracotomy. There were no complications, stayed 24 hours in the ICU and was in hospital 4 days. The technique was effective, allows easy accessibility surgical and quick post-operative recovery.

Videotoracoscopia para fechamento de fístula coronário-pulmonar: relato de caso / Video-thoracoscopy closure of coronary artery fistula: case report

As fístulas da artéria coronária (FAC) são raras e, muitas vezes, achado ocasional. O tratamento convencional é realizado por fechamento cirúrgico com toracotomia mediana ou por meio de embolização por procedimento hemodinâmico. Descrevemos uma técnica inovadora para ligadura da FAC de forma totalmente endoscópica. Mulher, 45 anos, com fístula sintomática entre artéria coronária descendente anterior e tronco de artéria pulmonar onde se realizou toracoscopia esquerda, pericardiotomia e ligadura do pertuito com clipe metálico. Não houve intercorrência, a paciente permaneceu 24 horas na UTI e teve alta hospitalar no 4º dia. A técnica foi efetiva, permitiu fácil acessibilidade cirúrgica e rápida recuperação pós-operatória.

Reações transfusionais: diagnóstico e tratamento / Transfusion reactions: diagnosis and treatment

A maior parte das transfusões resulta em reposição temporária, efetiva e segura de hemocomponentes. Como outras intervenções médicas, entretanto, as transfusões são associadas a certos riscos, e, somente quando os benefícios esperados sobrepõem os riscos potenciais, a transfusão deve ser iniciada. Este capítulo discorre sobre as principais categorias de reações transfusionais, discutindo a fisiopatologia, o diagnóstico, o tratamento, e a prevenção dessas reações
