OBJECTIVES: Bone cancers occur frequently in children, adolescents, and young adults aging 15 to 29 years. Osteosarcoma and Ewing sarcoma are the most frequent subtypes in this population. The aim of this study was to describe incidence and mortality trends of bone cancers among Brazilian children, adolescents and young adults. METHODS: Incidence information was obtained from 23 population-based cancer registries. Mortality data were extracted from the Atlas of Cancer Mortality from 1979 to 2013. Specific and adjusted rates per million were analyzed according to gender, morphology and age at diagnosis. Median rates were used as a measure of central tendency. Joinpoint regression was applied to analyze trends. RESULTS: Median incidence rates were 5.74 and 11.25 cases per million in children and young adults respectively. Osteosarcoma in the 15-19 years aged group had the highest incidence rates. Stable incidence rates were observed among five registries in 0-14 year's age group. Four registries had a decreased incidence trend among adolescents and young adults. Median mortality rates were 1.22 and 5.07 deaths per million in children and young adults respectively. Increased mortality was observed on the North and Northeast regions. Decreased mortality trends were seen in the South (children) and Southeast (adolescents and young adults). CONCLUSION: Osteosarcoma and Ewing Sarcoma are the most incident bone cancers in all Brazilian regions. Bone cancers showed incidence and mortality patterns variation within the geographic regions and across age groups, although not significant. Despite limitations, it is crucial to monitor cancer epidemiology trends across geographic Brazilian regions.

Resumo Objetivos: Os registros de câncer de base populacional (RCBP) e o Sistema Nacional de Nascidos Vivos (SINASC) possuem informações que possibilitam testar hipóteses sobre fatores de riscos associados às leucemias. O objetivo principal deste projeto é identificar quais as características ao nascimento das crianças que estariam associadas ao risco de desenvolver Leucemia Aguda (LA) na primeira infância. Métodos: Foram utilizadas informações de 12 RCBP e do Sistema de Informação de Nascidos Vivos das mesmas localidades. Foram elegíveis 272 casos e 1.088 controles no período de 1996 a 2010. As associações de riscos de LA foram agrupadas em, (i) características da criança ao nascer, e (ii) características de exposição materna durante a gestação da criança. A relação de casos e controles foi de 1:4. As análises para padronização, estruturação do banco de dados e análises estatísticas foram realizadas através dos aplicativos Excel, R-Studio e SPSS 21. Resultados: Houve associação entre anomalias congênitas (RC 3,62, IC95% 1,19-11,00) e exposição ocupacional materna a produtos químicos (OR 2,18, p 0,002) com o risco do desenvolvimento de LA. Conclusão: A utilização de banco de dados secundários populacionais para a identificação de fatores de risco para LA fortaleceu o intercâmbio de conhecimentos e melhoria das bases de dados, e contribuiu para investigações sobre as associações de riscos nas leucemias agudas em contexto mundial.

Abstract Objective: The population-based cancer registries (PBCR) and the Information System on Live Births in Brazil (Sistema de Informações sobre Nascidos Vivos [SINASC]) have information that enables the test for risk factors associated with leukemia at an early age. The aim of this study was to identify maternal and birth characteristics associated with early-age acute leukemia (EAL) in Brazil. Methods: A case-cohort study was performed using secondary dataset information of PBCR and SINASC. The risk association variables were grouped into (i) characteristics of the child at birth and (ii) characteristics of maternal exposure during pregnancy. The case-control ratio was 1:4. Linkage was performed using R software; odds ratio (OR) and 95% confidence interval (CI) were calculated by logistic regression models. Results: EAL was associated with maternal occupational exposure to chemicals (agricultural, chemical, and petrochemical industry; adjOR: 2.18, 95% CI: 1.16-4.10) and with birth defects (adjOR: 3.62, 95% CI: 1.19-11.00). Conclusions: The results of this study, with the identification of EAL risk factors in population-based case-cohort study, strengthen the knowledge and improve databases, contributing to investigations on risk factors associated with childhood leukemia worldwide.

ABSTRACT Objective To analyze the relationship between the development of childhood solid tumors and 1) birth weight and 2) fetal growth, using two Brazilian population-based data sets. Methods A case–cohort study was performed using two population-based data sets, and linkage between the Live Birth Information System (Sistema de Informação sobre Nascidos Vivos, SINASC) and 14 population-based cancer registries (PBCRs) was established. Four controls per case were chosen randomly from the SINASC data set. Tumors were classified as central nervous system (CNS), non-CNS embryonal, and other tumors (“miscellaneous”). Adjustments were made for potential confounders (maternal age, mode of delivery, maternal education, birth order, gestational age, sex, and geographic region). Odds ratios (ORs) with 95% confidence intervals (CIs) were computed using unconditional logistic regression analysis. Results In a trend analysis, for every 500 g of additional birth weight, the crude OR was 1.12 (CI: 1.00–1.24) and the adjusted OR was 1.02 (CI: 0.90–1.16) for all tumors. For every 1 000 g of additional birth weight, the crude OR was 1.25 (CI: 1.00–1.55) and the adjusted OR was 1.04 (CI: 0.82–1.34) for all tumors. Among children diagnosed after reaching the age of 3 years, in the miscellaneous tumor category, the OR was significantly increased for every additional 500 g and 1 000 g of birth weight. Conclusions The study data suggested that increased birth weight was associated with childhood solid tumor development, especially among children more than 3 years old with “miscellaneous” tumors.

RESUMEN Objetivo Analizar la relación entre la aparición de tumores sólidos en la niñez y 1) el peso al nacer y 2) el crecimiento fetal, a partir de dos conjuntos de datos poblacionales del Brasil. Métodos Se efectuó un estudio de casos en una cohorte a partir de dos conjuntos de datos poblacionales y se vinculó el sistema de información de nacidos vivos (Sistema de Informação sobre Nascidos Vivos, SINASC) con 14 registros oncológicos poblacionales. Se eligieron al azar cuatro controles por caso del conjunto de datos del SINASC. Los tumores se clasificaron en tres tipos: del sistema nervioso central (SNC), embrionarios ajenos al SNC y otros (“misceláneos”). Se hicieron ajustes en función de los posibles factores de confusión (edad materna, modalidad de parto, educación materna, orden de nacimiento, edad gestacional, sexo y región geográfica) y se calcularon las razones de posibilidad (OR) con un intervalo de confianza (IC) del 95 % mediante análisis de la regresión logística incondicional. Resultados En el análisis de las tendencias, se observó que, en todos los tumores, cada 500 g adicionales de peso al nacer la OR bruta fue de 1,12 (IC: 1,00-1,24) y la OR ajustada, de 1,02 (IC: 0,90-1,16), mientras que, cada 1 000 g adicionales, la OR bruta fue de 1,25 (IC: 1,00-1,55) y la OR ajustada, de 1,04 (IC: 0,82-1,34). En cuanto a los niños diagnosticados después de los 3 años de edad, en la categoría de tumores misceláneos, la OR fue significativamente más alta con cada 500 g y 1 000 g adicionales de peso al nacer. Conclusiones Los datos del estudio indican que el peso alto al nacer está asociado a la aparición de tumores sólidos en la niñez, especialmente de la categoría “misceláneos” y en los niños mayores de 3 años de edad.

Dentre os principais benefícios da adrenalectomia laparoscópica (AL) frente à adrenalectomia aberta (AA) destaca-se a rápida recuperação dos pacientes com diminuição do tempo de internação. O objetivo deste estudo foi comparar a adrenalectomia aberta com a adrenalectomia laparoscópica em suínos. Foram operados 32 suínos, distribuídos em quatro grupos (n=8), sendo um grupo submetido à AA e outro grupo à AL, com seus respectivos grupos controle. Foram avaliados parâmetros referentes a tempo operatório, temperatura corporal, hematócrito, intercorrências operatórias e tempo de deambulação. Não houve diferença significativa entre os tempos operatórios e de deambulação, apesar deste último ter sido maior no grupo submetido à AA. As intercorrências mais frequentes foram acidentes em alças intestinais, lesões em vasos adrenais e hematoma renal. As perdas sanguíneas não foram significativas, a hipotermia observada não apresentou repercussão clínica. A laparoscopia para adrenalectomia experimental em suínos é uma técnica confiável podendo servir como referência para o tratamento de doenças adrenais com indicações cirúrgicas em outras espécies animais. Palavras-chave: glândulas supra-renais; irrigação sanguínea; videocirurgia.

Among the main benefits of laparoscopic adrenalectomy (LA) compared to open adrenalectomy (OA) the rapid recovery of patients with decreased length of stay in hospital can be highlighted. The objective of this study was to compare the open adrenalectomy with laparoscopic adrenalectomy in swine. Thirty-two swine were operated. The animals had been divided into four groups (n = 8), one group was submitted to OA and the other to LA, together with its respective control group. Parameters were evaluated regarding operative time, body temperature, hematocrit, postoperative and intraoperative complications and time to deambulation. There was no meaningful difference between operative and deambulation times, even though the latter having been higher in the group submitted to OA. The most frequent intercurrences were in bowel, damage to adrenal vessels and renal hematoma. There were no significant blood losses, and observed hypothermia did not have any clinical impact. Laparoscopy in swine experimental adrenalectomy is a reliable technique that can serve as a reference for the surgical treatment of patients with adrenal diseases with surgical indications in other animal species.

OBJECTIVES: Childhood cancer mortality has substantially declined worldwide as a result of significant advances in global cancer care. Because limited information is available in Brazil, we analyzed trends in childhood cancer mortality in five Brazilian regions over 29 years. METHODS: Data from children 0-14 years old were extracted from the Health Mortality Information System for 1979 through 2008. Age-adjusted mortality rates, crude mortality rates, and age-specific mortality rates by geographic region of Brazil and for the entire country were analyzed for all cancers and leukemia. Mortality trends were evaluated for all childhood cancers and leukemia using joinpoint regression. RESULTS: Mortality declined significantly for the entire period (1979-2008) for children with leukemia. Childhood cancer mortality rates declined in the South and Southeast, remained stable in the Middle West, and increased in the North and Northeast. Although the mortality rates did not unilaterally decrease in all regions, the age-adjusted mortality rates were relatively similar among the five Brazilian regions from 2006-2008. CONCLUSIONS: Childhood cancer mortality declined 1.2 to 1.6% per year in the South and Southeast regions.

O objetivo foi descrever a distribuição da incidência de câncer de cólon e reto em Fortaleza, Ceará, e Porto Alegre, Rio Grande do Sul, no Brasil, e a tendência temporal da doença entre 1990-1999. Foram calculadas taxas médias anuais de incidência ajustadas por idade e a variação percentual anual estimada (estimated annual percent change - EAPC) das taxas, por sexo, utilizando-se os registros de câncer de base populacional. O EAPC apontou aumento das taxas em Porto Alegre e Fortaleza para homens, +4,2% (p = 0,14) e +9,3% (p < 0,001), e mulheres, +4,6% (p = 0,11) e +5,3% (p = 0,15), respectivamente. As taxas médias de incidência ajustadas foram cerca de três vezes maiores em Porto Alegre do que em Fortaleza, tanto para homens (25,1 vs. 8,6/100 mil) quanto para mulheres (19,9 vs. 7,1/100 mil). O aumento das taxas de incidência pode ser devido a estratégias de detecção precoce do câncer, mudanças no estilo de vida das pessoas e a alterações da estrutura etária da população. Um perfil populacional semelhante ao de países desenvolvidos pode justificar as maiores taxas de incidência encontradas em Porto Alegre. Apesar disso, Fortaleza apresentou os maiores incrementos para o período.

The aim of this study was to describe the incidence distribution of colorectal cancer in Fortaleza, Ceará State, and Porto Alegre, Rio Grande do Sul State, Brazil, and the time trend in the disease from 1990 to 1999. Mean annual age-adjusted incidence rates and estimated annual percent change were calculated by gender, using population-based cancer registries. EAPC showed an increase in the rates in Porto Alegre and Fortaleza for men, +4.2% (p = 0.14) and +9.3% (p < 0.001), and women, +4.6% (p = 0.11) and +5.3% (p = 0.15), respectively. The mean adjusted incidence rates were three times higher in Porto Alegre than in Fortaleza both for men (25.1 vs. 8.6/100 thousand) and women (19.9 vs. 7.1/100 thousand). This rise in incidence rates may be due to early cancer detection strategies, lifestyle changes, and alterations in the population age structure. A population profile similar to that of developed countries may explain the higher incidence rates in Porto Alegre. However, Fortaleza showed the largest increases during the period studied.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

A senescência é provocada por mudanças fisiológicas e bioquímicas como degradação do amido e clorofila, aumento da respiração e produção de etileno. O tratamento de flores cortadas com STS constitui uma das formas de inibir a produção ou ação do fitormônio. Para avaliar os efeitos do STS, em combinação ou não com sacarose, aplicado em solução de condicionamento, sobre a longevidade e a qualidade de inflorescências cortadas de lírio, variedade Ace, hastes com 3 botões de diferentes idades, foram tratadas com solução de sacarose 5% por 12 horas; solução de STS 1mM por 15 minutos; solução de STS (15 minutos) + solução de sacarose por 12 horas e controle (água destilada). Foram avaliados: comprimento e abertura dos botões, teor relativo de água e teor de clorofila na folha e longevidade. A longevidade das inflorescências de lírio, variedade Ace, é influenciada pelos estádios de colheita, obtendo-se maior longevidade no estádio mais jovem, A. Inflorescências colhidas no estádio A apresentam maior diâmetro quando pré-tratadas com STS; todavia, este tratamento compromete a abertura dos botões e a qualidade das flores. A sacarose possibilita a abertura dos botões colhidos no estádio A e aumento da vida útil da flor. Assim, o uso de solução de sacarose, na concentração de 5% permite a colheita de inflorecências de lírio em estádio prematuro, obtendo-se maior vida de vaso da flor cortada.

Flower senescence is triggered by physiological changes including degradation of starch and chlorophyll, increase in respiration and ethylene production. Pulsing of cut flowers with STS is one efficient way to inhibit ethylene action and production. To evaluate the effects of STS combined or not with sucrose on flower longevity and quality, lily inflorescences cv. Ace were pulsed with 5% sucrose for 12 hours, 1mM STS for 15 minutes, STS + sucrose and control (distilled water) in inflorescences harvested with three bud flowers at different ages. They were evaluated at length and opening of the buds, relative water content, content of chlorophyll and longevity. The longevity of lilly flowers variety Ace is influenced by the stage of harvest, with longer longevity for the younger stage, A. Inflorescences harvested at stage A and pulsed with STS had bigger diameter, but the treatment reduced the bud opening and flower quality. The sucrose improved the opening of buds harvested at stage A and increased the flower vase life. Thus the use of sucrose at 5% allowed harvesting the inflorescences at earlier stage, increasing the flower vase life.
