ABSTRACT. The present study aimed to develop and evaluate an automated cooling control system (ATCE) for sows in the farrowing phase. The experiment was conducted at the Swine Production Unit, Federal Institute of Education, Science and Technology, Campus Machado, Machado, state of Minas Gerais. Sixteen sows and their offspring were evaluated, eight treated and eight controls, in a randomized block design, with eight replications. Surface temperature, body temperature and respiratory rate of the animals were evaluated, in addition to floor temperature and performance parameters. The use of ATCE decreased the floor temperature (12h) and neck temperature (12 and 16h) (p < 0.10). In addition, there was a reduction in rectal temperature (12h) and respiratory rate (12 and 16h) in ATCE animals (p < 0.10). No significant differences were detected in the coefficient of variation (CV) of birth weight, but at weaning the CV of piglet weight was 26.3% lower in animals subjected to the ATCE (p = 0.079). Furthermore, the difference in CV between birth and weaning was also lower with the use of ATCE (p = 0.015). It can be concluded that the use of ATCE has a positive influence on the thermal comfort of females, in addition to improving litter uniformity.

ABSTRACT BACKGROUND: It is known that elective inguinal hernioplasties are safe procedures, but in an emergency setting, they have higher rates of complications and hospital costs. Despite this, quantitative studies on the subject in Brazil are still scarce. AIMS: To evaluate the trend in hospitalization rates, hospital mortality, and costs for inguinal hernia in an emergency, regarding gender and age group. METHODS: This is a time series study with data from the Unified Health System (SUS), at the national level, from 2010 to 2019. RESULTS: The overall hospitalization rate (p=0.007; b<0,02) in all age groups (p<0.005; b<0) in both genders indicated a decreasing trend. The general mortality rate in both genders and in most age groups showed an increasing trend (p<0.005), as well as the cost of hospitalization in all age groups of both genders. CONCLUSIONS: Urgent hospitalization rates for inguinal hernia in Brazil have shown a steady or decreasing trend; however, hospital mortality and costs per hospitalization have demonstrated an increasing trend in recent years.

RESUMO RACIONAL: Sabe-se que as hernioplastias inguinais eletivas são procedimentos seguros, mas que, em caráter de urgência, têm maiores taxas de complicações e custos hospitalares. Apesar disso, ainda são escassos os estudos quantitativos sobre o tema no Brasil. OBJETIVOS: Avaliar a tendência das taxas de internação, mortalidade hospitalar e custos por hérnia inguinal em caráter de urgência, quanto ao sexo e faixa etária. MÉTODOS: Trata-se de um estudo de séries temporais com dados do Sistema Único de Saúde (SUS), em nível nacional, no período de 2010 a 2019. RESULTADOS: A taxa de internação geral (p=0,007; b<0,02) em todas as faixas etárias (p<0,005; b<0) nos dois sexos indicou tendência decrescente. A taxa de mortalidade geral em ambos os sexos e na maioria das faixas etárias apresentou tendência crescente (p<0,005), assim como o custo da internação em todas as faixas etárias de ambos os sexos. CONCLUSÕES: As taxas de internação em caráter de urgência por hérnia inguinal, no Brasil, apresentaram tendência estacionária ou decrescente, entretanto, a mortalidade hospitalar e os custos por internação mostraram tendência crescente nos últimos anos.

Abstract Background Cardiovascular diseases are the leading cause of adult mortality. Geographically remote and low-income Brazilian regions lack specialized consultations. The telemedicine management of this population by cardiologists is not fully known. Objectives To analyze cardiology teleconsultation in the Brazilian region with the highest number of isolated cities. Methods From February 2020 to October 2021, patients from the North Region of Brazil evaluated by local general practitioners were referred for cardiological evaluation by telemedicine. Referral reasons, demographics, clinical history, physical examinations, tests, medications, and prescriptions pre- and post-telemedicine were analyzed (p<0.05 was considered statistically significant). Results We analyzed 653 patients. The attendance rate was 85.7% (53.1% female, mean age: 54.2±6.5 years). The main reasons for referral were cardiovascular symptoms (58.1%) and risk factors among asymptomatic patients (13.3%). Only 12.6% had a diagnosed disease. Most patients had regular physical examinations and electrocardiograms. Few had recent complementary tests. The prescription of angiotensin receptor blockers (ARBs), calcium channel blockers and statins was significantly increased, while that of digoxin, noncardiac beta-blockers and acetylsalicylic acid (ASA) was decreased at the first teleconsultation. Most of the tests requested were of low complexity and cost: electrocardiogram (28.2%), chest X-ray (14%), echocardiogram (64.5%) and blood tests (71.8%). For 2.1% of patients, interventions were indicated, and 8% were discharged after the first consultation. Conclusion On-demand cardiology teleconsultation contributes to heart disease treatment optimization. Most patients were referred with syndromic diagnoses without previous complementary tests. The specialist workup requested was usually available locally and at a low cost but precluded early discharge. Local training could optimize the referral.

Resumo Fundamento As doenças cardiovasculares são a principal causa de morte no mundo. Regiões brasileiras geograficamente remotas e de baixa renda carecem de consultas especializadas. Não se tem conhecimento total acerca do manejo por telemedicina dessa população por parte de cardiologistas. Objetivos Analisar a teleconsulta cardiológica na região brasileira com maior número de municípios isolados. Métodos Entre fevereiro de 2020 e outubro de 2021, pacientes da Região Norte do Brasil avaliados por médicos generalistas locais foram encaminhados para avaliação cardiológica por telemedicina. Foram analisados os motivos do encaminhamento, dados demográficos, histórico clínico, exames físicos, exames complementares, medicamentos e prescrições pré e pós-telemedicina (considerou-se p<0,05 como estatisticamente significativo). Resultados Analisamos 653 pacientes. A taxa de frequência foi de 85,7% (53,1% do sexo feminino, idade média: 54,2±6,5 anos). Os principais motivos de encaminhamento foram sintomas cardiovasculares (58,1%) e fatores de risco entre pacientes assintomáticos (13,3%). Apenas 12,6% apresentava alguma doença diagnosticada. A maioria dos pacientes havia passado por exame físico e eletrocardiogramas regulares. Poucos tinham exames complementares recentes. A prescrição de bloqueadores dos receptores da angiotensina (BRA), bloqueadores dos canais de cálcio e estatinas aumentou significativamente, enquanto a de digoxina, betabloqueadores não cardíacos e ácido acetilsalicílico (AAS) diminuiu na primeira teleconsulta. A maioria dos exames complementares solicitados era de baixa complexidade e custo: eletrocardiograma (28,2%), radiografia de tórax (14%), ecocardiograma (64,5%) e exames de sangue (71,8%). Para 2,1% dos pacientes, foram indicadas intervenções, e 8% recebeu alta após a primeira consulta. Conclusão A teleconsulta cardiológica sob demanda contribui para a otimização do tratamento das doenças cardíacas. A maioria dos pacientes foi encaminhada com diagnósticos sindrômicos sem exames complementares prévios. A avaliação especializada solicitada geralmente estava disponível localmente e com baixo custo, mas impedia a alta precoce. Capacitação local poderia otimizar o encaminhamento.

SUMMARY OBJECTIVE: Risk stratification of sudden cardiac death in patients with coronary artery disease is of great importance. We evaluated the association between ventricular repolarization and induction of malignant ventricular arrhythmias on electrophysiological study of patients with coronary artery disease. METHODS AND RESULTS: A total of 177 patients (65±10.1 years, 83.6% male, mean left ventricular ejection fraction [LVEF] 37.5±13.6%) were analyzed. For each 10 ms increment in the QT interval, there was a 7% increase in malignant ventricular arrhythmias inducibility; QT cutoff point of 452 ms had an accuracy of 0.611 for predicting malignant ventricular arrhythmias (p=0.011). Male gender (odds ratio [OR]=4.18, p=0.012), LVEF <35% (OR=2.32, p=0.013), amiodarone use (OR=2.01, p=0.038), and prolonged QT (OR=1.07, p=0.023) were associated with malignant ventricular arrhythmias. In patients with ventricular dysfunction, QT >452 ms was associated with significantly increased risk of malignant ventricular arrhythmias (OR=5.44, p=0.0004). In those with LVEF ³35%, QT dispersion (QTd) was significantly higher in patients with inducible malignant ventricular arrhythmias. QTd >20 ms had 0.638 accuracy and 81.3% negative predictive value in predicting malignant ventricular arrhythmias. CONCLUSION: QT interval is an independent factor associated with malignant ventricular arrhythmias in patients with coronary artery disease. The combination of ventricular dysfunction and prolonged QT interval is associated with a 5.44-fold increase of malignant ventricular arrhythmias induction. Male gender, amiodarone use, and decreased left ventricular ejection fraction are also associated with increased risk of inducibility of malignant ventricular arrhythmias on the electrophysiological study.

RESUMO Objetivo: Comparar a confiabilidade interobservador da mensuração da morfologia do psoas e lordose lombar nas diferentes posições e padronizar a realização do exame de ressonância magnética em posição prona e lateral. Métodos: Trata-se de um estudo transversal realizado com voluntários assintomáticos de ambos os sexos, maiores de 18 anos, sem alterações patológicas conhecidas na região lombar. Foi realizada ressonância magnética da coluna lombar na posição supina, decúbito lateral direito e prono, obtendo imagens nas sequências ponderadas em T2 nos planos sagital e axial. Foram medidas as distâncias do psoas até o platô vertebral e o plexo lombar. Os exames foram avaliados por dois ortopedistas independentes em caráter cego. Resultados: Houve ótima concordância entre as medições do tamanho da vértebra (ICC=0.92), baixa concordância para a distância do plexo (ICC = 0,63) e alta concordância para a margem anterior (ICC = 0,84). Conclusão: Houve boa reprodutibilidade das medidas propostas, sugerindo que a técnica em posição lateral e prona é capaz de gerar imagens de qualidade. Nível de Evidência 3B; Prospectivo.

ABSTRACT Objective: To compare the interobserver reliability of measurements of psoas morphology and lumbar lordosis in different positions and to standardize the performance of magnetic resonance imaging in the prone and lateral positions. Methods: This is a cross-sectional study carried out with asymptomatic volunteers of both sexes, aged over 18 years, with no known pathological changes in the lumbar region. Magnetic resonance imaging of the lumbar spine was performed in the supine, right lateral decubitus and prone positions, obtaining images in T2-weighted sequences in the sagittal and axial planes. The distances were measured from the psoas to the vertebral plateau and from the psoas to the lumbar plexus. The exams were assessed by two independent, blinded orthopedists. Results: There was excellent agreement between the measurements of vertebral size (ICC=0.92), low agreement for plexus distance (ICC=0.63) and high agreement for the anterior margin (ICC=0.84). Conclusion: There was good reproducibility of 2 of the 3 measures proposed, suggesting that the technique in the lateral and prone positions is capable of generating quality images. Level of Evidence 3B; Prospective.

RESUMEN Objetivo: Comparar la fiabilidad interobservador de la medición de la morfología del psoas y la lordosis lumbar en diferentes posiciones y estandarizar la realización de la resonancia magnética en decúbito prono y lateral. Métodos: Se trata de un estudio transversal realizado con voluntarios asintomáticos de ambos sexos, mayores de 18 años, sin alteraciones patológicas conocidas en la región lumbar. Se realizó la resonancia magnética de la columna lumbar en decúbito supino, decúbito lateral derecho y prono, obteniendo imágenes en las secuencias potenciadas en T2 en los planos sagital y axial. Se midieron las distancias del psoas a la meseta vertebral y al plexo lumbar. Los exámenes fueron evaluados a ciegas por dos ortopedistas independientes. Resultados: Hubo una excelente concordancia entre las mediciones del tamaño de la vértebra (ICC = 0,92), una baja concordancia para la distancia del plexo (ICC = 0,63) y una alta concordancia para el margen anterior (ICC = 0,84). Conclusión: Hubo buena reproducibilidad de las medidas propuestas, lo que sugiere que la técnica en decúbito lateral y prono es capaz de generar imágenes de calidad. Nivel de evidencia 3B; Prospectivo.

ABSTRACT Objective Adhesive capsulitis is an inflammatory disease of the joint capsule, clinically manifested as pain, stiffness, and dysfunction of the shoulder. We subjectively observed an increased incidence of adhesive capsulitis, and raised the hypothesis that adhesive capsulitis was more frequent in magnetic resonance imaging examinations performed during the COVID-19 pandemic as compared with examinations prior to this period. Methods Data from medical records and magnetic resonance imaging of the shoulder presenting typical imaging findings of adhesive capsulitis, performed in our organization from March to June 2020, were evaluated and compared with data and imaging from the same period of the previous year. To this end, an organizational business intelligence tool called “search reports” was used, searching for the term “adhesive capsulitis” in the radiological report, results were tabulated, and corresponding magnetic resonance imaging exams were analyzed. Results Our search found a total of 240 and 1,373 cases of adhesive capsulitis in the 2020 and 2019 periods, respectively. The mean age of patients was 53.9 years in the 2020 group and 49.9 years in 2019 (p<0.001). Magnetic resonance imaging findings were positive for adhesive capsulitis in 40 out of 240 shoulders (16.7%) in the 2020 group versus 127 out of 1,373 shoulders (9.2%) in the 2019 group. This difference was statistically significant (p=0.001). Conclusion Our study findings suggest a relative increase in the proportion of magnetic resonance imaging findings suggestive of adhesive capsulitis cases during COVID-19 pandemics based on data from our organization.

RESUMO JUSTIFICATIVA E OBJETIVOS: As artralgias crônicas observadas em pacientes acometidos pela febre Chikungunya trazem repercussões que impactam negativamente a vida desses indivíduos. O objetivo primário deste estudo foi avaliar a prevalência, as articulações acometidas e a intensidade das artralgias em indivíduos na fase crônica da febre Chikungunya. O objetivo secundário foi identificar fatores associados à presença das artralgias nesses indivíduos. MÉTODOS: Estudo de corte transversal, que avaliou 80 voluntários, de ambos os sexos, com faixa etária entre 20-80 anos e diagnóstico clínico e/ou laboratorial de febre Chikungunya. A avaliação das artralgias foi realizada por meio do Nordic Questionnaire of Musculoskeletal Symptoms e a intensidade das dores pela escala analógica visual. RESULTADOS: 91% (n=73) da amostra relataram artralgias persistentes, a cerca de 34,7±2,20 meses, com maior predomínio pela manhã (50,7%). As articulações que apresentaram maior prevalência das dores foram joelhos (68,8%), tornozelos (66,3%) e os punhos (63,8%). Joelhos (4,81±0,40), tornozelos (4,66±0,42) e as metacarpofalangeanas (4,33±0,43) foram as articulações com maior intensidade das dores e o sobrepeso foi um fator associado à presença das artralgias (p=0,002). CONCLUSÃO: Foi observada uma elevada prevalência das artralgias, de caráter recorrente e maior predomínio pela manhã. As articulações mais acometidas pelas dores foram joelhos, tornozelos e os punhos e as artralgias foram mais intensas nos joelhos, tornozelos e metacarpofalangeanas. O sobrepeso foi um fator associado à presença das artralgias nos indivíduos acometidos pela febre Chikungunya.

ABSTRACT BACKGROUND AND OBJECTIVES: Chronic arthralgias caused in patients affected by Chikungunya fever bring repercussions that negatively impact the lives of these individuals. The primary objective of this study was to observe the prevalence, affected joints and intensity of the arthralgias in individuals in the chronic phase of Chikungunya fever. The secondary objective was to identify the factors associated with the presence of the arthralgias in these individuals. METHODS: Cross-sectional study that evaluated 80 volunteers, of both genders, with age range between 20-80 years, with clinical and/or laboratory diagnosis of Chikungunya fever. The arthralgias were assessed using the Nordic Questionnaire of Musculoskeletal Symptoms and pain intensity using the visual analog scale. RESULTS: 91% (n=73) of the sample reported recurrent arthralgias, at approximately 34.7±2.20 months, with a greater predominance in the morning (50.7%). The joints that showed the highest prevalence of pain were knees (68.8%), followed by the ankles (66.3%) and wrists (63.8%). Knees (4.81±0.40), ankles (4.66±0.42) and metacarpophalangeal (4.33±0.43) were the joints with greatest pain intensity. In addition to that, overweight was associated with the presence of arthralgias (p=0.002). CONCLUSION: A high prevalence of arthralgias was observed, of a recurrent character and a greater predominance in the morning. The joints most affected by pain were knees, ankles and the wrists and arthralgias were more intense in the knees, ankles and metacarpophalangeal joints. Overweight was a factor associated with the presence of arthralgias in individuals affected by Chikungunya fever.

Resumo Objetivo Descrever a vigilância ativa dos eventos adversos pós-vacinação, sua incidência e fatores associados, em um município de Minas Gerais, Brasil. Métodos Coorte prospectiva realizada na Atenção Primária à Saúde, entre 2017 e 2018. Foram acompanhados 384 indivíduos que receberam vacinas, excluindo-se aqueles que tiveram eventos adversos prévios. Na linha de base, foram coletadas informações sociodemográficas, de saúde e histórico de vacinação e, no seguimento, as características do evento adverso e das ações de vigilância epidemiológica. Estimou-se taxa de incidência de eventos adversos, e realizaram-se o teste do qui-quadrado, a regressão de Poisson e o teste de Hosmer-Lemeshow. Resultados A incidência de eventos adversos foi de 13,36 casos/100 mil doses de vacinas (intervalo de confiança de 95%: 13,34-13,38), com maior incidência em crianças menores de 5 anos. Os eventos adversos mais frequentes foram dor local, vermelhidão, endurecimento, seguidos de febre e choro persistente. Dentre os fatores associados à ocorrência dos eventos adversos, recebimento da vacina contra tétano e difteria (risco relativo: 7,9; intervalo de confiança de 95%: 2,77-12,46) e administração por meio da via intramuscular foram considerados de risco (risco relativo: 6,1; intervalo de confiança de 95%: 2,55-14,63). A conduta do profissional de enfermagem, diante das orientações sobre as vacinas recebidas, aumentou a notificação de eventos adversos (risco relativo: 3,4; intervalo de confiança de 95%: 1,53-7,68). Conclusão O estudo permitiu conhecer fatores que favorecem a ocorrência de eventos adversos. Há evidências de que condutas adotadas pelos profissionais de enfermagem nas salas de vacinação podem evitar subnotificações de eventos adversos pós-vacinação.

Abstract Objective To describe the active surveillance of adverse events following immunization, their incidence and associated factors in a municipality of Minas Gerais, Brazil. Methods This is a prospective cohort conducted in Primary Health Care between 2017 and 2018. A total of 384 individuals who received vaccines were followed up, excluding those who had previous adverse events. At baseline, sociodemographic, health and vaccination history information and, in follow-up, the characteristics of adverse events and epidemiological surveillance actions were collected. The incidence rate of adverse events was estimated, and the chi-square test, poisson regression and Hosmer-Lemeshow test were performed. Results The incidence of adverse events was 13.36 cases/100,000 doses of vaccines (95% confidence interval: 13.34-13.38), with a higher incidence in children under 5 years of age. The most frequent adverse events were local pain, redness, hardening, followed by fever and persistent crying. Among the factors associated with the occurrence of adverse events, receiving tetanus and diffrhyphria vaccine (relative risk: 7.9; 95% confidence interval: 2.77-12.46) and intramuscular administration were considered at risk (relative risk: 6.1; 95% confidence interval: 2.55-14.63). Nursing professionals’ conduct, considering the guidelines on the vaccines received, increased adverse event reporting (relative risk: 3.4; 95% confidence interval: 1.53-7.68). Conclusion The study allowed to know factors that favor the occurrence of adverse events. There is evidence that conducts adopted by nursing professionals in immunization rooms may avoid underreporting of adverse events following immunization.

Resumen Observación Describir la observación activa de los eventos adversos posvacunación, su incidencia y factores asociados en un municipio del estado de Minas Gerais, Brasil. Métodos Cohorte prospectiva realizada en la Atención Primaria de Salud, entre 2017 y 2018. Se realizó el seguimiento de 384 individuos que recibieron vacunas, excluyendo a aquellos que tuvieron eventos adversos previos. En la línea basal, se recopiló información sociodemográfica, de salud e historial de vacunación y, en el seguimiento, las características del evento adverso y las acciones de observación epidemiológica. Se estimó un índice de incidencia de eventos adversos y se realizó la prueba χ2 de Pearson, la regresión de Poisson y la prueba de Hosmer-Lemeshow. Resultados La incidencia de eventos adversos fue de 13,36 casos/100.000 dosis de vacuna (intervalo de confianza de 95 %: 13,34-13,38), con mayor incidencia en niños menores de 5 años. Los eventos adversos más frecuentes fueron dolor local, enrojecimiento, endurecimiento, seguidos de fiebre y llanto persistente. Entre los factores asociados a la ocurrencia de los eventos adversos, la aplicación de la vacuna contra el tétanos y la difteria (riesgo relativo: 7,9; intervalo de confianza de 95 %: 2,77-12,46) y la administración por medio de la vía intramuscular fueron considerados de riesgo (riesgo relativo: 6,1; intervalo de confianza de 95 %: 2,55-14,63). La conducta del profesional de enfermería ante las instrucciones sobre las vacunas recibidas aumentó la notificación de eventos adversos (riesgo relativo: 3,4; intervalo de confianza de 95 %: 1,53-7,68). Conclusión El estudio permitió conocer factores que favorecen a la ocurrencia de eventos adversos. Hay evidencias de que las conductas adoptadas por los profesionales de enfermería en las salas de vacunación pueden evitar subnotificaciones de eventos adversos posvacunación.

RESUMO A utilização de fibras de aço no concreto vem recebendo forte atenção pela possibilidade de reduzir significativamente o consumo de barras de aço nas estruturas de concreto armado. Entretanto, ainda são poucos os trabalhos encontrados sobre a durabilidade de concreto com fibra de aço e sobre o desempenho da ancoragem das barras metálicas em concretos reforçados e submetidos a ataques de íons cloreto. Buscando contribuir para o melhor entendimento do assunto, este trabalho apresenta resultados para 12 (doze) amostras prismáticas (100x100x250) mm3. Cada amostra recebeu uma barra de aço de 8 mm de diâmetro que foram divididas em 2 (dois) grupos iguais, sendo que um grupo foi submetido ao ensaio de corrosão acelerada por imersão modificada (CAIM) e o outro não, avaliando-se os danos ocasionados pelo ataque de íons cloreto tanto nas barras quanto nas fibras de aço. Cada grupo apresentou 3 (três) amostras com 1% de fibra de aço e outros 3 (três) sem fibra, e os comprimentos de ancoragem (lb) foram de 100 %, 75 % e 50 % necessário daquele recomendado pela norma Brasileira NBR 6118. Verificou-se que não há comprometimento da perda de aderência das barras com o substrato de concreto, quando reduzido o (lb) em 25 % garantindo a funcionalidade, podendo resultar em redução de custos. Observou-se ainda que nas amostras submetidas a corrosão com fibras ou sem fibras houve perda de massa, não sendo constatado que a presença de fibras possa ter contribuído para reduzir essa perda, contudo é possível observar uma relação direta entre o menor valor de (lb) e a menor perda de massa.

ABSTRACT The implementation of steel fibers in concrete has received strong attention, for the possibility of significantly reducing steel bar’s consumption in reinforced concrete structures. However, a small number of articles is found on the durability of steel fiber concrete and the performance of anchorage length, when submitted to chloride ion attacks. Seeking to contribute to the better understanding of the subject, this paper presents results for 12 (twelve) prismatic samples (100x100x250) mm³. Each sample received a steel bar within 8 mm in diameter, and these were divided into 2 (two) equal groups, which only the first group was subjected to the modified immersion accelerated corrosion test, in order to evaluate the damage caused by the attack of chloride ions on both bars and steel fibers. Each group presented 3 (three) samples with 1% of steel fiber and another 3 (three) without fiber, and the anchorage lengths (lb) vary between 100%, 75% and 50%, as recommended by Brazilian standard NBR 6118. It was verified that there was no compromise related to the adhesion’s loss between steel bar and concrete substrate, when reduced the (lb) by 25% and guarantees functionality, which can result in cost reduction. In addition, the corrosion resulted in a loss of 50% of the value of the maximum pullout load.

Abstract Ephyrae are the young scyphozoan jellyfishes that usually passes unnoticed, whereas their adult counterparts play major ecological roles and can negatively affect economic activities when they occur in high densities. We describe, for the first time, wild ephyrae of Lychnorhiza lucerna (Scyphozoa, Rhizostomeae) from the Patos Lagoon Estuary, Southern Brazil. A total of 10 ephyrae were found in salinities between 12 and 33 and temperatures between 16 and 27°C. The presence of digitata, eight oral arms and serrated tips on marginal lobes allowed species determination. Wild ephyrae were morphologically identical to laboratory-cultivated individuals. The youngest individual was about one to two days old, and the most developed one, between 12 and 14 days old. Recruitment of L. lucerna probably initiated during warmer months (December until February) because nine out of ten individuals were found in high temperature (> 20° C) and salinity (> 30) waters. On the other hand, a mid-winter occurrence of a single ephyra (T=16° C, S= 12) demonstrates that the species may support a considerable range of variation in the physical environment. We reinforce the importance of long-term studies to provide information about the species coupling with seasonal cycles and the dynamics of estuarine and coastal areas.

A gasolina é uma mistura complexa de substâncias, dentre elas estão hidrocarbonetos como o benzeno, tolueno, etilbenzeno e xilenos (BTEX), sendo esses compostos emitidos para a atmosfera, com destaque ao benzeno, por ser comprovadamente carcinogênico. Objetivamos avaliar as concentrações de BTEX no ar de postos de revenda de combustíveis no Município do Rio de Janeiro, Brasil, e calcular o risco de câncer associado a estas exposições. Foram realizados dois tipos de amostragem (fixa e móvel) adaptadas da metodologia nº 1.501 do Instituto Nacional de Segurança e Saúde Ocupacional (Estados Unidos), em seis postos de revenda de combustíveis na Zona Oeste da cidade. A amostragem fixa foi feita próxima às bombas de combustível, enquanto a móvel foi realizada através da coleta do ar na zona respiratória dos trabalhadores (frentistas), conforme estes se deslocavam pelo posto. As amostras foram analisadas por cromatografia gasosa com detecção por ionização em chama. Com os resultados das amostragens foram feitos os cálculos de risco à saúde, usando os indicadores Quociente de perigo (HQ) e Risco de câncer (CR), para avaliar os possíveis efeitos não-carcinogênicos e carcinogênicos, respectivamente, nos trabalhadores dos postos de revenda de combustíveis. As concentrações ambientais para a maioria dos compostos BTEX foram abaixo dos limites preconizados, menos para o benzeno, um composto carcinogênico, que apresentou concentrações muito acima dos limites, levando a altos valores de risco de câncer. Os resultados demonstraram que há riscos à saúde dos trabalhadores de postos de revenda de combustíveis, principalmente o risco de desenvolver câncer, devido à exposição excessiva ao benzeno.

La gasolina es una mezcla compleja de sustancias, entre ellas existen hidrocarburos como el benceno, tolueno, etilbenceno y xilenos (BTEX), emitiéndose estos compuestos a la atmósfera, donde se destaca el benceno, al tratarse de un carcinogénico comprobado. Los objetivos fueron evaluar las concentraciones de BTEX en el aire de puestos de reventa de combustibles, en el municipio de Río de Janeiro, Brasil, así como calcular el riesgo de cáncer asociado a estas exposiciones. Se realizaron dos tipos de muestra (fija y movible), adaptadas de la metodología nº 1.501 del Instituto Nacional de Seguridad y Salud Laboral (EE.UU.), en seis puestos de reventa de combustibles de la zona oeste de la ciudad. La muestra fija se realizó cerca de las bombas de combustible, mientras que la móvil se hizo mediante tomas de aire en la zona respiratoria de los trabajadores (de la gasolinera), a medida que estos se desplazaban por el lugar de trabajo. Las muestras se analizaron por cromatografía gaseosa con detección por ionización en llama. Junto a los resultados de las muestras, se realizaron cálculos de riesgo para la salud, usando los indicadores Cociente de peligro (HQ) y Riesgo de cáncer (CR), con el fin de evaluar los posibles efectos no-carcinogénicos y carcinogénicos, respectivamente, en los trabajadores de los puestos de reventa de combustibles. Las concentraciones ambientales para la mayoría de los compuestos BTEX estuvieron por debajo de los limites preconizados, menos en el caso del benceno, un compuesto carcinogénico, que presentó concentraciones muy por encima de los límites, llevando a altos valores de riesgo de cáncer. Los resultados demostraron que existen riesgos para la salud de los trabajadores de puestos de reventa de combustibles, principalmente, riesgo de desarrollar cáncer, debido a la exposición excesiva al benceno.

Gasoline is a complex mixture of substances, including aromatic hydrocarbons such as benzene, toluene, ethylbenzene, and xylenes (BTEX). These compounds are emitted into the air, with the special relevance of benzene since it is provenly carcinogenic. The study aimed to assess BTEX concentrations in filling stations in the city of Rio de Janeiro, Brazil, and to calculate the cancer risk associated with such exposures. Two types of sampling were performed (stationary and mobile), adapted from methodology n. 1,501 (U.S. National Institute for Occupational Safety and Health) for aromatic hydrocarbons, in six filling stations in the West Zone of Rio de Janeiro. Stationary sampling was done near the fuel pumps, while mobile sampling was done in the breathing zone of the workers (station attendants) as they moved around the station. The samples were analyzed with gas chromatography flame ionization detector. The sampling results were used to calculate the health risk, using the indicators Hazard quotient (HQ) and Cancer risk (CR) to assess the possible non-carcinogenic and carcinogenic effects, respectively, in filling station workers. Environmental concentrations for the most of the BTEX compounds were below the recommended limits, except for benzene, a carcinogenic compound, which displayed concentrations far above the limits, leading to high cancer risk values. The results showed that there are health risks for filling station attendants, especially the risk of developing cancer from excessive exposure to benzene.
