RESUMO Objetivo: Mapear fatores internos e externos em uma unidade de emergência que interferem na prática comunicativa interprofissional. Método: Estudo de caso único realizado na unidade de emergência de um hospital geral. Os dados foram coletados por meio de observação participante, análise documental e entrevista semiestruturada, triangulados e submetidos à análise temática, a partir de categorias definidas a priori, baseadas na matriz SWOT. Resultados: Participaram 22 profissionais de saúde. Quanto aos pontos fortes e oportunidades, constatou-se que os profissionais compreendem a importância da comunicação como medida de segurança, utilizam a passagem de plantão e a comunicação escrita para compartilhar informações. Porém, a superlotação, a sobrecarga de trabalho, a ausência de padronização de condutas, a inexperiência de profissionais e o déficit no relacionamento interprofissional são fatores dificultadores de uma comunicação efetiva. Conclusão: O processo comunicativo interprofissional fragilizado dificulta a interação e o compartilhamento de informações para a tomada de decisões compartilhadas que possibilite a continuidade do cuidado de maneira segura.

ABSTRACT Objective: To map internal and external factors in an emergency care unit that interfere with interprofessional communicative practice. Method: This is a single case study carried out in the emergency care unit of a general hospital. Data were collected through participant observation, document analysis, and semi-structured interviews, and were triangulated and subjected to thematic analysis, out of categories defined a priori, based on the SWOT matrix. Results: Twenty-two health care professionals participated in the study. As for the strengths and opportunities, it was found that professionals understand the importance of communication as a safety measure, and they use the shift change and written communication to share information. However, overcrowding, work overload, the lack of behaviors standardization, the inexperience of professionals, and the deficit in the interprofessional relationship are factors that hinder effective communication. Conclusion: The fragile interprofessional communicative process hampers interaction and information sharing for shared decisions that allow the safe continuity of care.

ABSTRACT Propolis (bee glue) a product of Apis mellifera L. is a resinous mixture containing chiefly beeswax and resin harvested by bees from plant leaves, buds and exudates. Extracts of a propolis sample from Salitre, a municipality of Ceará state (northeast Brazil) were obtained with solvents of increasing polarity (hexane, chloroform, ethyl acetate and methanol). A chemical profile was carried out by GC–EI-MS and HPLC–DAD–ESI-MS/MS. Lupenone, lupeol, octanoic acid tetracosyl ester and octanoic acid hexacosyl ester were identified by GC–EI-MS. Antioxidant activity was evaluated by the DPPH and β-carotene discoloring methods, and anti-HIV activity by the in vitro inhibition of HIV-1 reverse transcriptase. The ethyl acetate extract exhibited the highest antioxidant and anti-HIV activity and was fractioned by column chromatography using silica gel and seven different eluents. The active fractions were submitted to semi preparative HPLC and the following compounds were isolated: caffeic acid, p-coumaric acid, diprenylcinnamic acid, quercetin, naringenin, isorhamnetin, quercetin-3-O-diglucoside,4,2′,4′-trihydroxy-2-methoxychalcone, gossypetin-3,3′,4′,7-tetramethyl ether, myricetin-3,7,3′-trimethyl ether and 5-hydroxy-3,6,7,8,4′-pentamethoxyflavone. The ethyl acetate extract and its fractions F5-F7, as well as quercetin, isorhamnetin, myricetin-3,7,3′-trimethyl ether and p-coumaric acid exhibited high antioxidant activity on both DPPH and β-carotene antioxidant methods. Isorhamnetin exhibited moderate inhibitory effect against HIV-1 reverse transcriptase (56.99 ± 3.91%), followed by naringenin (44.22 ± 1.71%), quercetin (43.41 ± 4.56%) and diprenylcinnamic acid (41.59 ± 2.59%). These results agree with previous authors who reported anti-HIV activity of flavonoids.

Biodiesel is an alternative fuel obtained from different biomass sources and processes. Nowadays, this biofuel has gained importance due to environmental concerns and rising energy demand. In the biodiesel production chain, stability is a critical issue, as it is linked to the maintenance of its original properties. This work performed a study evaluating the influence of storage conditions on the quality aspects of biodiesel. Thus, different samples of biodiesel obtained from soybean and frying oils were produced and placed in containers made by plastic, glass and tin, and stored in presence or absence of an oxidative atmosphere, moisture and light. These samples were analyzed to evaluate the ester content, acidity, iodine value, kinematic viscosity and oxidative stability. The characterization with GC-MS and GC/FID were done aiming to determine the chemical composition. Blends with frying biodiesel into soybean biodiesel have also been produced in concentrations ranging from 1%, 5% and 10% (m/m) in order to evaluate the mixing effect. In the initial storage time, all tested parameters were in accordance to the legislation. Distinct behaviors were identified for each sample according to the container type, being the glass the most effective of them in maintenance of biodiesel characteristics.

ABSTRACT Background: Zika virus (ZIKV) sexual transmission and prolonged viral shedding in semen have been previously reported, suggesting a strong viral affinity for genital tissues. A transient impact of ZIKV on male fertility was shown in animal and human studies. Methods: Adult male patients with confirmed ZIKV infection diagnosed in the city of Araraquara, Brazil during the epidemic season of 2016 were invited one year after the acute infection to respond to a questionnaire of genital symptoms and to provide a semen sample for molecular ZIKV testing and spermogram analysis, as well as a serum sample for hormonal testing. Results: 101 of 187 tested patients had positive ZIKV RT-PCR in plasma and/or urine samples (54%, 72 women and 29 men). Of 15 adult male participants for whom telephone contact was successful, 14 responded to the questionnaire of genital symptoms and six consented to provide a semen sample at a median of 12 months after the acute infection. We report abnormal spermogram results from patients one year after confirmed ZIKV infection. Conclusions: Our findings suggest a possible long-term detrimental effect of ZIKV infection on human male fertility that has to be further explored in well-characterized samples from cohort studies conducted in ZIKV-endemic areas.

Resumo Os dispositivos de fixação óssea, metálicos convencionais, usados em cirurgia crâniomaxilofacial têm apresentado alguns problemas, tais como, corrosão, inflamação e infecção, além de neoformação de estrutura óssea mecanicamente inferior devido à atrofia gerada pela diferença de módulo elástico entre metal e osso, razões que têm levado ao aumento do interesse por dispositivos poliméricos bioarreabsorvíveis. Os polímeros biorreabsorvíveis mais utilizados nesta aplicação pertencem à família dos poli (α-hidroxi ácidos), que têm como característica degradarem por hidrólise de suas ligações ésteres, tal como copolímero poli (L-ácido láctico-co-D, L ácido láctico), PLDLA. Neste trabalho foram investigados alguns efeitos da adição de poli (caprolactona triol), PCL-T sobre PLDLA. Foram preparados pinos por fusão de blendas nas seguintes composições 100/0, 90/10, 70/30 and 50/50 (m/m), PLDLA/PCL-T. Os pinos foram caracterizados por diferentes técnicas (DSC, MEV e ensaio mecânico). A degradação in vitro dos pinos foi investigada, sendo observado que a adição de PCL-T no PLDLA modificou suas propriedades mecânicas e morfológicas. Tais mudanças podem apresentar potencial para outras aplicações do material, onde a questão da flexibilidade se faça necessária.

Abstract The bone fixation devices, conventional metallic cranium used in surgery have presented some problems, such as corrosion, inflammation and infection, and a lower mechanically newly formed bone structure due to the atrophy caused by the difference in stiffness between metal and bone. These reasons have led to increased interest in bioreabsorbable polymeric devices. The most bioresorbable polymers used in this application belong to the family of poly (α-hydroxy acids), which are characterized degrade by hydrolysis of its ester linkages, such as copolymer poly (L-lactic acid-co-D, L lactic acid) (PLDLA). In this work was investigated some effects of the addition poly (caprolactone triol), PCL-T in the PLDLA. Pins were prepared by melting in the 100/0, 90/10, 70/30 and 50/50 (w/w) compositions, PLDLA/PCL-T. The pins were characterized by different methods (DSC, SEM and mechanical test). The in vitro pins degradation was investigated. It was observed that the addition of PCL-T of PLDLA modifies the mechanical properties, morphological, we conclude that PLDLA/PCL-T can be a potential material for various applications, where the question of flexibility to make necessary.

Abstract Insulating paper holds significant importance in the insulation system of power transformers, and thus, its degradation is the subject of many studies. A successful evaluation of the degradation rate of such paper contributes to reducing downtime and avoiding equipment failure. In this work, samples of thermally upgraded paper were thermally aged in insulating natural ester (INE) and insulating mineral oil (IMO) and were evaluated by degree of polymerization (DP) and FTIR-ATR. It was possible to identify characteristic bands of dicyandiamide, an inhibitory compound of the thermal degradation of the paper, and to establish a correlation between the decrease in DP and the consumption of dicyandiamide during aging, which was observed to develop in three distinct steps for both IMO and INE.

O nematóide Calodium hepaticum (sin. Capillaria hepatica) é um helminto zoonótico encontrado infectando principalmente ratos. A prevalência da infecção de C. hepaticum em Rattus norvegicus foi investigada em área urbana do Rio de Janeiro (Brasil) com baixo planejamento e saneamento. A presença de C. hepaticum foi identificada através da presença de lesões macroscópicas caracterizadas por manchas extensas de coloração branco-amarelada difusa por toda superfície do tecido do fígado e através de análise histológica. A prevalência total da infecção foi de 45% sem diferença significativa entre o sexo e idade. A presença de roedores infectados próximos do peridomicílio representa um risco substancial para a saúde humana.

It was studied the prevalence of C. hepaticum infection in Rattus norvegicus in an urban area of Rio de Janeiro (Brazil), with low urban planning and sanitation. The presence of C. hepaticum was identified through visible yellowish-white lesions in liver tissue and histological analyses. The total prevalence of infection was 45%, with no significant differences between sex and age. The presence of infected rodents near the peridomestic area poses substantial risk to human health.

The morphology and electrochemical behavior of niobium coating obtained by thermal plasma spray process on a substrate of steel API 5L X65 was evaluated. The coating was obtained, using electrical current of 500 A, 15 g/min of powder and 2.0 L/min of argon gas. The preparation of the substrate surface was performed with preheating and abrasive blasting with alumina. After thermal spraying, the morphology of the coating was analyzed by scanning electron microscopy (SEM), while the surface roughness was evaluated by profilometry, hardness by Vickers microhardness test and adhesion by bending at 180 °. The corrosion resistance of the coating was evaluated from the polarization test in 3.5% NaVl solution. The results show that the coating presented cracking and lack of padding between the plates sprayed, relative high hardness and deficient adhesion to the substrate. However, the values of current density carried by the system compared to uncoated steel were reduced.

Se evaluó la morfología y el comportamiento electroquímico del revestimiento de niobio obtenido por el proceso de aspersión térmica a plasma en substrato de acero API 5L X65. El revestimiento con niobio se realizó con una corriente eléctrica de 500 A, flujo de polvo metálico de niobio de 15 g/min y gas de argón de 2.0 L/min. La preparación superficial del substrato se realiza con pre-calentamiento y limpieza a presión con abrasivo de alúmina. La morfología del revestimiento fue analizada por microscopía electrónica de barrido (MEB), la rugosidad de la superficie se evaluó por perfilometría, la dureza por micro-dureza Vickers y la adherencia por ensayado de doblado a 180°. La resistencia a la corrosión del revestimiento se determinó mediante el ensayo de polarización en una solución de NaVl 3,5%. A partir de los resultados obtenidos fue posible verificar que el revestimiento presentó fisuras y poros entre las placas rociadas además de una dureza elevada en relación al substrato y adherencia no adecuada. Aún así los valores de densidad de corriente desarrollados por el sistema en comparación al acero revestido se redujeron.
