ABSTRACT The spatial and temporal variability of air pollutants in an urban area is great. Superimposed on daily meteorological variability are seasonal cycles of human activities that influence air quality. The objective of this research was to analyze the spatial and temporal variation of polluting gases: sulfur dioxide, nitrogen dioxide and ozone in two locations in Havana from November 2015 to October 2016. Hourly concentration data from two Automatic Atmospheric Monitoring Stations. The statistical processing of the data was carried out using the MS-Excel and Origin 2016 software. The non-pa rametric Mann-Whitney U, Kruskal-Wallis H, and Dunn tests were applied. In general, the concentrations of the pollutants corresponded to the distribution patterns characteristic of urban locations.

RESUMEN La variabilidad espacial y temporal de los contaminantes atmosféricos en un área urbana es grande. Superpuestos a la variabilidad meteorológica diaria existen ciclos estacionales de las actividades humanas que influyen en la calidad del aire. El objetivo de la presente investigación fue analizar la variación espacial y temporal de los gases contaminantes: dióxido de azufre, dióxido de nitrógeno y ozono en dos localidades de La Habana desde noviembre de 2015 hasta octubre de 2016. Se utilizaron datos horarios de concentración provenientes de dos Estaciones Automáticas de Monitoreo Atmosférico. El procesamiento estadístico de los datos fue realizado empleando los softwares MS-Excel y Origin 2016. Se aplicaron las pruebas no paramétricas U de Mann-Whitney, H de Kruskal-Wallis y Dunn. De forma general as concentraciones de los contaminantes se correspondieron con los patrones de distribución característicos de localidades urbanas.

RESUMO Antecedentes: Poucos estudos brasileiros investigaram fatores de risco para disfagia e suas complicações associadas em uma grande coorte. Objetivo: Investigar frequência, preditores e desfechos associados da disfagia em pacientes até três meses após acidente vascular cerebral (AVC). Métodos: Selecionamos pacientes admitidos consecutivamente em um centro especializado em AVC agudo. Excluímos pacientes com ataque isquêmico transitório, hemorragia subaracnóidea, trombose venosa cerebral, AVC hemorrágico de causa secundária, AVC não agudo ou aqueles que não consentiram em participar. A deglutição foi avaliada por fonoaudiólogos, por meio do teste de deglutição de volume-viscosidade. A função geral foi avaliada usando-se escala de Rankin modificada, índice de Barthel e medida de independência funcional. Resultados: Foram admitidos 831 pacientes e incluídos 305. A idade média foi 63,6±13,3 anos, o tempo médio da avaliação foi 4,2±4,1 dias e 45,2% apresentavam disfagia. Idade (razão de chances [OR] 1,02; intervalo de confiança [IC95%] 1,00-1,04; p=0,017), história médica conhecida de apneia obstrutiva do sono (OR=5,13; IC95% 1,74-15,15; p=0,003) e gravidade do AVC na admissão hospitalar (OR=1,10; IC95% 1,06-1,15; p<0,001) foram independentemente associados à disfagia. Disfagia (OR=3,78; IC95% 2,16-6,61; p<0,001) e gravidade do AVC (OR=1,05; IC95% 1,00-1,09; p=0,024) foram independentemente associadas com morte ou dependência funcional em três meses. Conclusões: A disfagia esteve presente em quase metade dos pacientes com AVC. Idade, apneia obstrutiva do sono e gravidade do AVC foram preditores de disfagia, que esteve independentemente associada com morte ou dependência funcional em três meses.

ABSTRACT Background: Few Brazilian studies investigated risk factors for dysphagia and associated complications in a large cohort. Objective: To investigate frequency, predictors, and associated outcomes of dysphagia in patients up to three months post-stroke. Methods: Prospective cohort study of consecutively admitted patients in a specialized center for acute stroke. Patients with a transient ischemic attack, subarachnoid hemorrhage, cerebral venous thrombosis, hemorrhagic stroke with secondary cause, non-acute stroke, or those who did not consent to participate were excluded. Swallowing was evaluated by speech language pathologists using Volume-Viscosity Swallow Test. General function at three months post-stroke was assessed using the following instruments: Modified Rankin scale, Barthel Index and Functional Independence Measure. Results: A total of 831 patients were admitted and 305 patients were included according to the inclusion and exclusion criteria. The mean age of patients was 63.6±13.3 years, mean time from stroke to swallowing assessment was 4.2±4.1 days, and 45.2% of the patients had dysphagia. Age (OR=1.02; 95%CI 1.00-1.04; p=0.017), known medical history of obstructive sleep apnea (OR=5.13; 95%CI 1.74-15.15; p=0.003), and stroke severity at hospital admission (OR=1.10; 95%CI 1.06-1.15; p<0.001) were independently associated with dysphagia. Dysphagia (OR=3.78; 95%CI 2.16-6.61; p<0.001) and stroke severity (OR=1.05; 95%CI 1.00-1.09; p=0.024) were independently associated with death or functional dependence at three months. Conclusions: Dysphagia was present in almost half of stroke patients. Age, obstructive sleep apnea, and stroke severity were predictors of dysphagia, which was independently associated with death or functional dependence at three months.

RESUMO Devido à ação dos óleos essenciais de tomilho, capim-limão e alecrim contra microrganismos e poucos estudos dos mesmos no tratamento de sementes, propõe-se este estudo com semente de hortaliça. Portanto, o objetivo deste trabalho foi avaliar o efeito do tratamento com óleos essenciais de tomilho, capim-limão e alecrim em sementes de couve-flor inoculadas com Aspergillus flavus. Foram utilizados os três óleos essenciais, nas concentrações 0,0; 0,4; 0,8; 1,6 e 2,0%, arranjados em esquema fatorial 3x5, no delineamento inteiramente casualizado, com quatro repetições. Os óleos essenciais de tomilho (1,8%) e capim-limão (1,9%) tiveram efeito fungistático contra A. flavus em sementes de couve-flor. Os óleos essenciais de tomilho a 2,0% e o de capim-limão a 1,6% não afetaram a qualidade fisiológica das sementes, sendo promissores no tratamento de sementes orgânicas. Por outro lado, o óleo essencial de alecrim, apesar de não afetar a germinação e afetar pouco o vigor das sementes, não foi eficiente no controle do patógeno.

ABSTRACT Due to the action of essential oils of thyme, lemongrass and rosemary against microorganisms and few studies on them in seed treatment, this study is proposed with vegetable seed. Therefore, the aim was to evaluate the effect of treatments with essential oils of thyme, lemongrass and rosemary on cauliflower seeds, inoculated with Aspergillus flavus. Three essential oils were used, at concentrations 0.0; 0.4; 0.8; 1.6 and 2.0%, arranged in a 3x5 factorial scheme, in a completely randomized design, with four replications. The essential oils of thyme (1.8%) and lemongrass (1.9%) had a fungistatic effect against A. flavus in cauliflower seeds. Thyme essential oil at 2.0% and lemongrass at 1.6% didn’t affect the physiological quality of seeds, being promising in the treatment of organic seeds. On the other hand, rosemary essential oil, despite not affecting germination and little affecting seed vigor, wasn’t efficient in controlling the pathogen.

ABSTRACT Purpose: To evaluate the effects of rosemary leaf essential oil-based ointments on the healing of rat skin lesions. Methods: Sixty adult male rats, with dorsal excisional skin wounds made surgically under anesthesia, were divided into three groups (n = 20): Sham group (untreated wounds); control group (CG, wounds treated with vehicle); and essential oil (EO) treated group (wounds treated with essential oil-based ointments), administered topically once daily. Skin wounds were evaluated at 4, 7, 14, and 21 days after EO or vehicle treatments. Lesions were analyzed macroscopically for the contraction degree. Formalin-fixed paraffin-embedded sections of skin wounds were used for histopathological evaluation. Results: Macroscopic evaluation showed wounds edges with thin crust without firmness and yellowish color, along with an improvement in wound contraction in EO group when compared to the other groups. A reduced inflammatory reaction, along with newly formed small diameter capillaries and more organized and elongated collagen fibers, were more frequently observed in EO group than in the other groups. Moreover, blood vessel number and collagen fibers density were significantly higher in EO group. Conclusions: Skin lesion treatment with rosemary leaf essential oil-based ointments accelerates the initial stages of healing, reduces inflammation, and increases angiogenesis, collagen fibers density, and wound contraction in rats.

Abstract This research aims to investigate sediment cores from a glaciomarine environment based on their petrophysical parameters to elucidate lithological and sedimentary issues, as well as to identify a geophysical signature based on their parameter’s response. To achieve this objective, six marine sediment cores were collected in the Central Bransfield Basin - Antarctica, the lengths ranging from 1.5 to 5.2 meters in water depths ranging from 304 to 1463 meters. The cores were submitted to different analyses and values from density, magnetic susceptibility, electrical resistivity, p-wave velocity, total gamma radiation, silt, clay and sand contents, and mean grain size for each core location were considered. Four large lithologies were identified according to their geological and geophysical characteristics. The first group is subglacial deformation till (GC16); the second is massive diamicton (GC13 and GC12), the third group is composed of diamictons from the basin (AM10) and lower slope (GC09); the fourth lithological group is composed of siliceous mud from an upper slope location (GC06A). The characteristics recorded across Central Bransfield Basin (from South Shetlands Islands to Antarctic Peninsula) highlighted the relationship between the lithological content and associated depositional processes with the geophysical proprieties as density and magnetic susceptibility.

RESUMO A diversidade de artrópodes-praga tem exigido a integração de diferentes métodos de controle. Assim, aplicações de óleos essenciais com atividade inseticida, repelente ou fagoinibidora, associadas às liberações de inimigos naturais, podem potencializar o manejo integrado de pragas, desde que apresentem seletividade. Nesse contexto, o objetivo foi avaliar a seletividade dos óleos de alecrim-pimenta Lippia origanoides Kunth (Verbenaceae), citronela Cymbopogon winterianus Jowitt. (Poaceae) e capim-santo C. citratus (DC) Stapf., sobre Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae), comparando cinco concentrações (0,01; 0,05; 0,1; 0,5 e 1,0%), além da testemunha (detergente neutro à 1,0%). Avaliou-se a toxicidade residual por meio da mortalidade de adultos, calculando-se concentrações letais (CL50), além das reduções no parasitismo em ovos de Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) e seletividade aos parasitoides. Os três óleos exibiram seletividade ao parasitoide T. pretiosum, causando mortalidade entre 17,2 (alecrim-pimenta) e 32,2% (capim-santo), na menor concentração. Destacou-se o óleo essencial de alecrim-pimenta com CL50 de 0,43%, apenas 22% de redução do parasitismo (Classe 1 - Inócuo) e 88% de emergência quando à 0,01%. A CL50 do óleo de capim-santo foi 0,15%, com 34% de redução do parasitismo (Classe 2 - Levemente nocivo) e 74% de adultos emergidos. Já para o óleo de citronela, a CL50 foi de 0,12%, 46% de redução (Classe 2 - Levemente nocivo) e emergência de 62%. A seletividade dos óleos essenciais encontrada pode viabilizar liberações de T. pretiosum, integrando controle biológico e inseticidas botânicos, à medida que ovos não pulverizados, sejam parasitados por T. pretiosum.

ABSTRACT The diversity of arthropod pests has required the combined use of various control methods. The application of essential oils showing insecticidal, repellent or phage-inhibiting activity, together with the release of natural enemies, can improve integrated pest management provided the oils display selectivity. The aim of this study was to evaluate the selectivity of the oils of rosemary pepper [Lippia origanoides Kunth (Verbenaceae)], citronella [Cymbopogon winterianus Jowitt. (Poaceae)] and lemongrass [C. citratus (DC) Stapf.] for Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae), comparing five concentrations (0.01, 0.05, 0.1, 0.5 and 1.0%), and a control (neutral detergent at 1.0%). Residual toxicity was evaluated using adult mortality, calculating lethal concentrations (LC50) in addition to the reductions in parasitism in eggs of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) and selectivity for the par asitoids. The three oils showed selectivity for the parasitoid T. pretiosum, resulting in a mortality rate of between 17.2% (rosemary pepper) and 32.2% (lemongrass) at the lowest concentration. The essential oil of rosemary pepper stood out with an LC50 of 0.43%, a reduction of only 22% in parasitism (Class 1 - Innocuous) and 88.0% emergence, at a dose of 0.01%. The LC50 of the lemongrass oil was 0.15%, with a 34.0% reduction in parasitism (Class 2 - Slightly harmful) and 74.0% emerged adults. For the citronella oil, the LC50 was 0.12%, with a reduction of 46.0% (Class 2 - Slightly harmful) and emergence of 62.0%. The selectivity of the essential oils makes possible to release T. pretiosum, integrating biological control with botanical insecticides, as long as non-sprayed eggs are parasitised by T. pretiosum.

Abstract The mangrove mussel Mytella falcata (d'Orbigny, 1846), synonym of M. charruana (d'Orbigny, 1842), has a good nutritional, functional and low cost value. The effect of refined or herb salts in the preparation of sururu burger was evaluated through the determination of proximate composition, cholesterol content, fatty acid profile and acceptability index. In herbs, phenols were evaluated. In both formulations, the protein content was above the minimum limit (15%) required by the Food Brazilian law, while the fat percentage was lower than the stablished (5%). Due to oxidation reactions, the total cholesterol content in the preparations supplemented with refined salt was significant lower (p ≤ 0.05) than that in the burgers without salt supplementation or with the herb salt. The fatty acids were more preserved in the preparation with herb salt, once the herbs are rich in phenols with high antioxidant capacity. Oregano had a significant higher content of total phenols (p ≤ 0.05), compared to rosemary and parsley. In relation to the flavor, as the Brazilian public is more adapted to more salty formulations, the acceptability index of the formulation with refined salt was significantly higher (p ≤ 0.05).

Abstract This paper evaluated the drying kinetics at different temperatures and the effect of the drying temperature on the physical-chemical properties and active compounds of the residue from the industrial processing of camu-camu. The drying temperatures of 40, 50, and 60 °C were evaluated. The residues dried at different temperatures were characterized in terms of their pH, water activity, anthocyanins, flavonoids, carotenoids, phenolic compounds and Fourier transform infrared spectroscopy. The parameters of the Page model showed the best adjustments to the experimental data. Drying affected the concentration of active compounds in the camu-camu residue. At 60 °C, the degradation of flavonoids, anthocyanins, and phenolic compounds was lower than in the dry residue, possibly because less time was required to achieve equilibrium in moisture content. Thus, in order to maintain higher concentrations of active compounds in the residue, drying at higher temperatures is recommended.

ABSTRACT Objectives: to identify the support provided to nursing students after a patient safety incident. Methods: qualitative study developed with 23 students attending an undergraduate nursing program in southern Brazil. Data were collected between September and November 2021 and submitted to textual discursive analysis using the Iramuteq software. Results: the students reported that mainly classmates and professors of the practical courses provided support. The students showed no knowledge of organizational support or protocols available to students who become second victims of such incidents. Final Considerations: the primary support sources available to nursing students involved in patient safety incidents were identified. Note that support provided to nursing students is still incipient both in Brazil and internationally. Hence, further studies are needed to address potential victims and support resources to mitigate this phenomenon.

Resumen Dos extractos comerciales (GUARDIAN TM 75 Romero, y GUARDIAN TM Green Tea Extract 20S) se evaluaron por su eficacia antioxidante en hamburguesas de cordero conservadas a 2ºC durante 9 días. Se utilizó un total de 9 kg de carne picada procediendo a la elaboración de las hamburguesas en 3 réplicas. En cada réplica se utilizaron 3 kg de carne las cuales fueron divididas en porciones de 1 kg, las cuales fueron mezcladas una la solución buffer mediante el agregado de 0,15 M de NaCl para cada tratamiento: 1) Control; 2) 400 ppm de extracto de té verde; y 3) 800 ppm de extracto de romero respectivamente. Las hamburguesas que contenían 400 y 800 ppm de extracto de té verde y romero respectivamente impidieron la oxidación lipídica, evaluado mediante la técnica de TBARS (P <0,05). El té verde a 400 ppm impidió la decoloración, manteniendo los valores de a* (índice de rojo) y el valor C* (intensidad de color) de las hamburguesas sin procesar durante el almacenamiento (p <0,05). Estos resultados indican que el té verde y el extracto de romero fueron efectivos en inhibir la oxidación de lípidos y el té verde conserva el color rojo durante el almacenamiento aeróbico y refrigerado de las hamburguesas de cordero sin procesar.

Abstract Two commercial antioxidant extracts (GUARDIAN TM 75, rosemary and GUARDIAN TM Green Tea Extract 20S) were evaluated for their antioxidant efficacy in lamb burgers preserved at 2 º C for 9 days. A total of 9 kg of minced meat was used, making the patties in 3 replicates. In each replication, 3 kg of meat were used, which were divided into 1 kg portions, which were mixed in a buffer solution by adding 0,15 M NaCl for each treatment: 1) Control, 2) 400 ppm of extract green tea and 3) 800 ppm rosemary extract respectively. Lamb patties containing 400 and 800 ppm of green tea and rosemary respectively prevented lipid oxidation, evaluated by the TBARS technique (P <0,05). Green tea at 400 ppm prevented discoloration, stabilizing the values of a * (red index) and the C * value (color intensity) of unprocessed patties during storage (p <0,05) These results indicated that green tea and rosemary extract were effective in inhibiting lipid oxidation and green tea preserves red color of raw lamb patties during aerobic and refrigerated storage.

Abstract The objective of this study was to evaluate high-concentrate diets and two energy sources on intake, performance and meat quality parameters of feedlot Nellore heifers. Twenty-eight heifers (200 ± 22.5 kg BW) were randomly assigned to four treatments in a 2×2 factorial arrangement: two concentrate levels (70 and 80%) and two energy sources (corn and corn germ meal). At the end of day 112, heifers were slaughtered. There was no interaction (P>0.05) of concentrate levels and energy sources for dry matter intake, unlike crude protein (CP) and neutral detergent fiber (NDF) intakes. The concentrate level of 80% and corn, allowed the highest CP (1.17 kg/day) and NDF (4.05 kg/day) intakes. Final BW (P<0.05) and daily gain (P<0.01) were influenced just by energy source. The carcass composition represented by muscle and fat was affected by concentrate level (P<0.05). Treatments affected (P<0.01) carcass fat deposition, global preference and texture of Longissimus muscle (P<0.05). It was concluded that high proportions of concentrate containing corn as energy source provided the best performance in heifers, and that the total replacement of corn with corn germ meal in high-concentrate diets is not recommended for performance Nellore heifers, but provided good sensory quality to the meat.

ABSTRACT The objective of this study was to evaluate the effect of the construction of the Jirau hydroelectric plant on the anopheline species, in Porto Velho, Rondônia, Brazil. For this, sampling was carried out in 23 locations in the pre (2004) and 23 after construction (2018) phases in the hydroelectric dam's coverage area, performed by human landing catch between 6:00 pm and 10:00 pm. We found 14 anopheline species. In the pre-construction phase, An. darlingi (73%) was the most abundant and after construction An. braziliensis (31.5%) was the most abundant. The T test indicated that there were no differences in the indexes – diversity (H '), richness (Sjack 1), equitability (J’) and dominance (d) of anophelines species - evaluated between the phases (p > 0.05). The spatio-temporal distribution of An. darlingi proved to be wide, with the highest density values observed in March ( x ¯w = 27.1) in the pre-construction phase and in the months of May ( x ¯w = 4) and July ( x ¯w = 3.1), post-construction. Differences in hematophagic activity peaks were observed between species and between phases. According to the data obtained in this study, the construction of the hydroelectric plant had little influence on the composition of anopheline species, however changes were observed in the spatio-temporal distribution of the An. darlingi and in the pattern of hematophagic activity of the species, which directly influenced the dynamics of malaria in the region.

Resumo A legislação do trabalho em vigência no Brasil intensificou formas mais flexíveis de contratação de força de trabalho e métodos de produção mais ajustáveis ao mercado, o que contribui para o aumento do desemprego no país. As mudanças afetaram diretamente a saúde mental dos trabalhadores, que passaram a se submeter a pressões e formas mais rígidas de contratação. Diante do cenário atual, este artigo objetiva analisar uma experiência de um grupo de apoio psicológico com trabalhadores em situação de desemprego, desenvolvido em uma clínica-escola de Psicologia da região Norte do Brasil. Foram realizados sete encontros, com média de duração de 90 minutos cada, o aceite foi estabelecido por meio do Termo de Consentimento Livre e Esclarecido. Os participantes tinham idades entre 37 e 51 anos, sendo dois homens e três mulheres; o tempo mínimo de desemprego foi de oito meses e o máximo de dois anos. Verificou-se que estes valorizavam o trabalho formal em detrimento do informal, pois o primeiro representava maior reconhecimento social, segurança e estabilidade profissional. A situação de desemprego gerou sentimentos de perda, humilhação e exclusão social que repercutiram no estado de humor, no aumento da ansiedade e do estresse. Conclui-se que a Psicologia pode oferecer suporte baseado em uma escuta acolhedora e compreensiva dos fenômenos ligados ao mundo do trabalho e/ou nas repercussões ligadas à subjetividade dos trabalhadores em situação de desemprego.

Abstract The labor legislation in force in Brazil has improved flexible forms of employment recruitment and labor-intensive production techniques, which contributes to the increase in the country unemployment rates. With the pressure and more rigid forms of hiring, these changes directly affected the mental health of workers. Considering that, this article aims to analyze the experience of a support group for unemployed workers developed in a school psychology clinic in Northern Brazil. The intervention consisted of seven meetings with an average duration of 90 minutes each, and the group was formed by two men and three women aged from 37 to 51 years, with minimum unemployment time of eight months and maximum of two years; all individuals agreed to participate by signing the Informed Consent Term. The participants reported preferring formal work over the informal one, for it represents greater social recognition, security, and professional stability. Unemployment evoked feelings of loss, humiliation, and social exclusion, besides impacting humor and heightening anxiety and stress. The results indicate that psychology can offer support based on a welcoming and comprehensive listening of phenomena related to the world of work and/or consequences of unemployment on workers’ subjectivity.

Resumen La nueva legislación laboral en Brasil intensificó formas más flexibles de contratación de fuerza laboral y métodos de producción más ajustables al mercado de trabajo, lo que contribuye al aumento del desempleo en el país. Los cambios afectaron directamente la salud mental de los trabajadores que pasaron a someterse a presiones y formas más rígidas de contratación. Ante el escenario actual, este artículo tiene como objetivo analizar la experiencia de un grupo de apoyo psicológico a trabajadores en situación de desempleo, desarrollado en una clínica-escuela de psicología de la región Norte de Brasil. Se realizaron siete reuniones, con media de duración de 90 minutos cada una, y se obtuvo el consentimiento por medio de la firma del documento de consentimiento informado. Los participantes tenían edades entre 37 y 51 años, siendo dos hombres y tres mujeres; el tiempo mínimo de desempleo fue de ocho meses y el máximo de dos años. Se observó que los participantes valoraban el trabajo formal en relación a lo informal, pues aquel les garantía un mayor reconocimiento social, seguridad y estabilidad profesional. La situación de desempleo les generó sentimientos de pérdida, humillación y exclusión social, que repercutieron en el estado de humor, en el aumento de la ansiedad y el estrés. Se concluye que la psicología puede brindar soporte por medio de una escucha acogedora y comprensiva de los fenómenos relacionados al mundo laboral y/o a las repercusiones asociadas a la subjetividad de los trabajadores en situación de desempleo.

Abstract The objective of this study was to evaluate the behavior of active compounds concentration present in the industrial by-product of acerola during drying using convective dehydration at 40, 50 and 60 °C. For this, flavones and flavonols, total proanthocyanidins, vitamin C, total phenolic content and antioxidant capacity as function of drying time were determined. The drying data were adjusted using the models of Page, Lewis, Henderson & Pabis, Modified Page and Logarithmic. In relation to the applied models, Page model presented the best fit. Acerola by-products dried at 40 °C showed higher concentrations of active compounds and higher antioxidant capacity. Although the drying process provoked changes in concentration of the active compounds, in the studied temperature range, significant concentrations of those bioactive compounds were observed. Thus, acerola by-product may present potential for application in different foods.
