ABSTRACT Introduction: Transfusion of red blood cells is recurrent in cardiac surgery despite the well-established deleterious effects. Identifying patients with higher chances of requiring blood transfusion is essential to apply strategic preventive measures to reduce such chances, considering the restricted availability of this product. The most used risk scores to predict blood transfusion are the Transfusion Risk and Clinical Knowledge (TRACK) and Transfusion Risk Understanding Scoring Tool (TRUST). However, these scores were not validated for the Brazilian population. The objective of this study was to assess the accuracy of TRACK and TRUST scores in estimating the need for postoperative transfusion of red blood cell concentrates (TRBCC) after cardiac surgery. Methods: A clinical retrospective study was conducted using the database of a Brazilian reference service composed of patients operated between November 2019 and September 2021. Scores were compared using Mann-Whitney U test. Hosmer-Lemeshow goodness of fit test assessed calibration of the scores. Accuracy was assessed using the area under the receiver operating characteristic curve (AUC). All analyses considered a level of significance of 5%. The study was approved by the research ethics committee (CAAE 55577421.4.0000.5201). Results: This study assessed 498 patients. Only the TRACK score presented good calibration (P=0.238; TRUST P=0.034). AUC of TRACK was 0.678 (95% confidence interval 0.63 to 0.73; P<0.001), showing a significant accuracy. Conclusion: Between the scores analyzed, only the TRACK score showed a good calibration, but low accuracy, to predict postoperative TRBCC after cardiac surgery.

ABSTRACT This work aimed to evaluate the effect of nitrogen dose management on the growth responses and physiological performance of barley seeds. Two barley cultivars (BRS Brau and BRS Cauê) and four nitrogen doses were used. The experimental design consisted of randomized blocks in a 2 X 4 factorial scheme (cultivars BRS Brau and BRS Cauê x nitrogen doses 120, 150, 180, and 210 kg ha-1). Successive collections of primary data were performed every fourteen days for growth analysis. The analyzed variables were total dry matter, dry matter production and relative growth rate, assimilated partition, and seed electrical conductivity. Increasing nitrogen doses caused a temporal-quantitative difference in growth, partition, and the accelerated aging test of barley seeds. The 150 kg ha-1 N dose resulted in total dry matter over time (Wt) superiority for both evaluated cultivars. The variable dry matter production rate achieved an increase with the 150 kg ha-1 N dose at 70 days after emergence (DAE) for BRS Brau and at 56 DAE for BRS Cauê supporting Wt. The 180 and 150 kg ha-1 N doses increased the relative growth rate for BRS Brau and BRS Cauê.

RESUMEN Este trabajo tuvo como objetivo evaluar el efecto del manejo de las dosis de nitrógeno en las respuestas de crecimiento y el rendimiento fisiológico de las semillas de cebada. Se utilizaron dos cultivares de cebada (BRS Brau and BRS Cauê) y cuatro dosis de nitrógeno. El diseño experimental consistió en bloques al azar en un esquema factorial 2 X 4 (cultivares BRS Brau y BRS Cauê x dosis de nitrógeno 120, 150, 180 y 210 kg ha-1). Se realizaron recolecciones sucesivas de datos primarios cada catorce días para el análisis de crecimiento. Las variables analizadas fueron materia seca total, producción de materia seca y tasa de crecimiento relativa, partición asimilada y conductividad eléctrica de las semillas. El aumento de las dosis de nitrógeno causa una diferencia cuantitativa-temporal en el crecimiento, partición y la prueba de envejecimiento acelerado de las semillas de cebada. La dosis de 150 kg ha-1 N resultó en una superioridad total de la materia seca en el tiempo (Wt) para ambos cultivares evaluados. La tasa variable de producción de materia seca logró un aumento para la dosis de 150 kg ha-1 N a los 70 días después de la germinación (DAE) para BRS Brau y a 56 DAE para BRS Cauê apoyando Wt. Las dosis de 180 y 150 kg ha-1 N aumentaron la tasa de crecimiento relativo para BRS Brau y BRS Cauê.

RESUMO Objetivo. Avaliar, por meio de métodos semiparamétricos de análise de sobrevida, a relação entre covariáveis e tempo até a morte em pacientes com câncer de mama e determinar o poder discriminatório na árvore de inferência condicional em pacientes que tiveram câncer. Métodos. Estudo de coorte retrospectivo realizado a partir de dados coletados de prontuários médicos de mulheres com câncer de mama, tratadas entre 2005 e 2015 no Hospital da Fundação Assistencial da Paraíba em Campina Grande, no estado da Paraíba, Brasil. As curvas de sobrevida foram estimadas pelo método de Kaplan-Meier, regressão de Cox e árvore de decisão condicional. Resultados. As pacientes com subtipos moleculares de tumor triplo-negativo tiveram uma sobrevida menor em comparação com as que apresentavam tumor com receptores hormonais. O acréscimo de hormonioterapia reduziu o risco de morte em 5,5%. O risco de morte foi 34,5% menor em pacientes com HER2+ quando comparadas às que tinham tumores sem a expressão desse gene. A mediana de sobrevida das pacientes tratadas com hormonioterapia foi de 4 753 dias. Conclusões. A presente análise revela um cenário favorável para o uso de imunoterapia em pacientes com superexpressão de HER2. Outros estudos devem ser realizados para avaliar a eficácia da imunoterapia em outras doenças e os fatores que favorecem o prognóstico e melhoram a qualidade de vida dessas pessoas.

ABSTRACT Objective. To evaluate, using semiparametric methodologies of survival analysis, the relationship between covariates and time to death of patients with breast cancer, as well as the determination discriminatory power in the conditional inference tree of patients who had cancer. Methods. A retrospective cohort study was conducted using data collected from medical records of women who had breast cancer and underwent treatment between 2005 and 2015 at the Hospital da Fundação de Assistencial da Paraíba in Campina Grande, State of Paraiba, Brazil. Survival curves were estimated using the Kaplan–Meier method, Cox regression, and conditional decision tree. Results. Women with triple-negative molecular subtypes had a shorter survival time compared to women with positive hormone receptors. The addition of hormone therapy reduced the risk of a patient dying by 5.5%, and the risk of a HER2-positive patient dying was 34.5% lower compared to those who were negative for this gene. Patients undergoing hormone therapy had a median survival time of 4 753 days. Conclusions. This paper shows a favorable scenario for the use of immunotherapy for patients with HER2 overexpression. Further studies could assess the effectiveness of immunotherapy in patients with other conditions, to favor the prognosis and better quality of life for the patient.

ABSTRACT Objective: To compare the agreement of clinical and radiographic diagnosis with the histopathological diagnosis in fibro-osseous lesions of the jaws. Material and Methods: An analytical and exploratory study was made based on systematic collected data, carried out in the laboratory of surgical pathology of a public Dental School. There were evaluated cases of fibrous dysplasia (FD), cemento-osseous dysplasia (COD) and ossifyng fibroma (OF), diagnosed by clinical, radiographic (panoramic and periapical radiography), and histopathological analysis, in a period of 12 years (from March 2001 to June 2013). Descriptive and inferential statistics (Fisher's exact test) were obtained. Results: Ninety-six cases of FOLs were evaluated. The radiographic aspects of the FOLs studied did not differ significantly (p=0.09). Radiolucent lesions were the least frequent, corresponding to approximately 13.5% of radiographic findings. Mixed lesions and radiopaques were more present, how they were COD and FD, respectively. The more aggressive variation of OF (Juvenile Ossifying Fibroma - JOF) was less frequent among the pathologies evaluated. In approximately 61.46% of the cases clinical and radiographic diagnosis were confirmed by histopathological diagnosis of FOLs. The highest agreement and the highest disagreement were observed in COD cases (40.7% and 62.2%, respectively). Conclusion: FOLs of the maxillaries represent a group of lesions in which the establishment of the clinical and radiographic diagnosis supported by the histopathological confirmation is critical and challenging.

Abstract In this paper, the authors present a proposal for an application of electromagnetic bandgap (EBG), for suppression of grating lobes, in frequency selective surfaces (FSS), not yet studied in the literature. An alternative type of EBG with square holes was proposed to reduce the computational effort in simulations. The study consists of an application of a rectangular periodic array of cylindrical and square holes in FSS dielectric substrate to create rejection bands and suppress specific resonant frequency modes. We built four prototypes and compared measured results with simulated results obtained with ANSYS HFSS. Simulations and measurements show suppression levels up to 6 dB. A good agreement between the results is observed. The FSS with EBG with square holes allows a simulation time 70 % lower than FSS with EBG with cylindrical holes.

Abstract Aims: To present to the scientific community the transposition of the printed version to the electronic version of the WebCas questionnaire. Methods: The transposition of the printed version to the electronic version of the WebCas questionnaire was carried out using the service of a computer programming professional. Through a response interface, the students had access to instructions to respond to the questionnaire. The MySQL 5 method was used to store the information, allowing the generation of reports. To record the responses, students were instructed to click on the chosen option. In case of error, they should choose another option, changing the option chosen previously. The “next” arrow indicated that the individuals being evaluated could change the page. Results: The WebCas questionnaire presented several functionalities related to its presentation and filling out process. In the restricted access to maintenance activities, it is possible to visualize 8 icons: 1 - questionnaire (information regarding the completion and development methodology of the questionnaire); 2 - students (registration information, anthropometric data and student code); 3 - activities (name of the activity, the domain such activity is inserted, intensities and values in MET’s); 4 - questions (statement and category of the question); 5 - graphs (showing the results of each question in the bar or pie format graphs); 6 - reports (reports export). Conclusion: The WebCas questionnaire is a technological resource that will assist health researchers in the collection, storage, and preliminary processing of information regarding health-related behaviors in schoolchildren.

Abstract INTRODUCTION Five months after the first confirmed case of COVID-19 in Brazil, the country has the second highest number of cases in the world. Without any scientifically proven drug or vaccine available combined with COVID-19’s high transmissivity, slowing down the spread of the infection is a challenge. In an attempt to save the economy, the Brazilian government is slowly beginning to allow non-essential services to reopen for in-person customers. METHODS: In this study, we analyze, based on data analysis and statistics, how other countries evolve and under which conditions they decided to resume normal activity. In addition, due to the heterogeneity of Brazil, we explore Brazilian data of COVID-19 from the State Health Secretaries to evaluate the situation of the pandemic within the states. RESULTS: Results show that while other countries have flattened their curves and present low numbers of active cases, Brazil continues to see an increase in COVID-19 patients. Furthermore, a number of important states are easing restrictions despite a high percentage of confirmed cases. CONCLUSIONS: All analyses show that Brazil is not ready for reopening, and the premature easing of restrictions may increase the number of COVID-19-related deaths and cause the collapse of the public health system.

RESUMO Objetivo: Analisar os fatores sociodemográficos e do estilo de vida associados ao excesso de peso (EP), à obesidade abdominal (OA) e à presença simultânea de EP e OA em adolescentes do Sul do Brasil. Métodos: Estudo transversal de base escolar realizado com 583 adolescentes (11 a 17 anos) da cidade de Criciúma, Santa Catarina. O EP foi avaliado pelo índice de massa corpórea (IMC) e a OA, mediante perímetro da cintura (PC). As variáveis independentes analisadas foram sexo, idade, escolaridade materna, dieta balanceada, atividade física, uso de cigarro, uso de álcool em excesso e tempo de tela. Utilizou-se regressão logística binária para estimar as razões de chances (RC) e intervalos de confiança de 95% (IC95%). Resultados: Os meninos tiveram 58% de chances a mais de terem EP (RC 1,58; IC95% 1,08-2,29; p<0,05). Menor faixa etária (11 a 14 anos) foi diretamente associada a maiores chances de EP (RC 6,07; IC95% 4,05-9,11; p<0,05). Adolescentes cujas mães tinham maior escolaridade apresentaram 75% de chances a mais de terem OA (RC 1,75; IC95% 1,01-3,00; p<0,05). Maiores chances para a simultaneidade EP e OA (RC 1,84; IC95% 1,01-3,34; p<0,05) foram identificadas nos adolescentes de menor faixa etária (11 a 14 anos). Conclusões: Meninos e menor faixa etária (11 a 14 anos) estiveram associados a maiores chances para EP. Os adolescentes cujas mães estudaram nove anos ou mais apresentaram maiores chances de terem OA. Menor faixa etária (11 a 14 anos) esteve associada a maiores chances para a presença simultânea de EP e OA.

ABSTRACT Objective: To analyze the sociodemographic and lifestyle factors associated with excessive weight (EW), abdominal obesity (AO) and the simultaneous presence of EW and AO in adolescents from Southern Brazil. Methods: Cross-sectional study with 583 adolescents (11 to 17 years old) of Criciúma, Santa Catarina, Brazil. EW was assessed by body mass index (BMI) and AO by waist circumference (WC). The independent variables analyzed were gender, age, maternal schooling, balanced diet, physical activity, cigarette use, excessive alcohol use and screen time. Binary logistic regression was used to estimate Odds Ratios (OR) and 95% confidence intervals (95%CI). Results: Boys had 58% higher likelihood of having EW (OR 1.58; 95%CI 1.08-2.29; p<0.05). Younger age group (11 to 14 years) was directly associated with higher likelihood of EW (OR 6.07; 95%CI 4.05-9.11; p<0.05). Adolescents whose mothers had higher education had 75% more likelihood of having AO (OR 1.75; 95%CI 1.01-3.00; p<0.05). Higher likelihood for EW and AO (OR 1.84; 95%CI 1.01-3.34; p<0.05) was identified in younger adolescents (11 to 14 years). Conclusions: Boys and younger age (11 to 14 years) were associated with a higher likelihood of EW. Adolescents whose mothers studied nine years or more were more likely to have AO. The younger age group (11 to 14 years) was associated with greater chances for the simultaneous presence of EW and AO.

Corrosion of buried pipelines is a matter of concern to the oil and gas industry since the time when carbon steel began to be widely used in these pipelines for the transportation of fluids. The microbial communities associated with biofilms promote modification in the surrounding environment and may accentuate the degradation of oil and gas pipelines causing leaks or even accidents. This work aimed to evaluate corrosion and biofilm formation in carbon steel API 5LX60 coupons buried in clayey soil from an industrial region in north-eastern Brazil. The average corrosion rates were determined by gravimetric test and the quantification of bacteria and fungi were using the Most Probable Number (MPN) and Colony Forming Units (CFU) techniques respectively. The results showed a great influence of clayey soil on corrosion rates and time of adherence for microorganisms on metal surfaces.

ABSTRACT Mangrove ecosystem dynamics and diverse human activities have led to a need for studies that give us a better understanding of the peculiarities of their soils. The objective of this study was to evaluate the physical and chemical soil attributes of mangrove forests located in the São Francisco River estuary, related to local ecological conditions. Two stations, divided into three forest types (fringe, basin and transition) were selected and five composite soil samples were collected from each forest type. Soil samples were submitted for chemical and physical analysis. The soil presented a sandy texture, with high organic matter and element content in the following order: Mg2+>Na+>Ca2+ >H+>K+>P>Al3+ and Fe2+ >Zn2+>Cu2+>Mn2+, respectively, with variations between the forests and stations. In general, the mangrove forests presented high fertility, especially in the basin forest, provided by vegetation development, showing a zoning trend for species in relation to soil fertility.

Resumo O desenvolvimento de modelos alométricos espécie-específicos é fundamental para a melhoria das estimativas de biomassa aérea, bem como para a estimativa do estoque e sequestro de carbono em florestas de mangue. Este estudo desenvolveu equações alométricas para estimar a biomassa aérea de Rhizophora mangle nos manguezais do estuário do rio São Francisco, nordeste do Brasil. Usando uma amostra de 74 árvores, análises de regressão linear simples foram usadas para testar a dependência da biomassa (total e por parte da planta) do tamanho, considerando dados transformados (Ln) e não transformados. As melhores equações foram aquelas com menor erro padrão da estimativa (SEE) e maior coeficiente de determinação ajustado (R2a). As equações ln-transformadas apresentaram melhores resultados, com R2a próximo a 0,99 na maioria dos casos. As equações para partes reprodutivas apresentaram valores baixos de R2a, o que pode ser atribuído ao caráter sazonal deste compartimento. "Área basal2×Altura" demonstrou ser o melhor preditor, presente na maioria das equações melhor ajustadas. Os modelos aqui apresentados podem ser considerados preditores confiáveis da biomassa aérea de R. mangle no manguezal do Nordeste brasileiro, bem como em qualquer local onde esta espécie de ampla distribuição assemelhe-se à arquitetura das árvores utilizadas no presente estudo.

Abstract The development of species-specific allometric models is critical to the improvement of aboveground biomass estimates, as well as to the estimation of carbon stock and sequestration in mangrove forests. This study developed allometric equations for estimating aboveground biomass of Rhizophora mangle in the mangroves of the estuary of the São Francisco River, in northeastern Brazil. Using a sample of 74 trees, simple linear regression analysis was used to test the dependence of biomass (total and per plant part) on size, considering both transformed (ln) and not-transformed data. Best equations were considered as those with the lowest standard error of estimation (SEE) and highest adjusted coefficient of determination (R2a). The ln-transformed equations showed better results, with R2a near 0.99 in most cases. The equations for reproductive parts presented low R2a values, probably attributed to the seasonal nature of this compartment. "Basal Area2 × Height" showed to be the best predictor, present in most of the best-fitted equations. The models presented here can be considered reliable predictors of the aboveground biomass of R. mangle in the NE-Brazilian mangroves as well as in any site were this widely distributed species present similar architecture to the trees used in the present study.

RESUMO Objetivou-se avaliar a inclusão de betaína na ração de fêmeas suínas no terço final de gestação e na lactação, quanto ao desempenho reprodutivo, composição do leite e avaliação econômica. Foram utilizadas 72 matrizes suínas, sendo 36 de primeiro ciclo (171,77 ± 7,54 kg) e 36 de segundo ciclo reprodutivo (203,17 ± 13,31 kg), distribuídas em delineamento em blocos ao acaso, em esquema fatorial 2 x 3, sendo dois ciclos reprodutivos e três rações (R0: ração controle; R1: ração com inclusão de 0,2% de betaína e redução de 50% da exigência em metionina digestível; R2: ração controle suplementada com 0,2% de betaína). A adição de betaína às dietas não promoveu efeito no peso ao parto, peso ao desmame das porcas, peso médio dos leitões ao nascimento e ao desmame, embora leitões provenientes de porcas de segundo ciclo tenham apresentado maior peso ao nascimento e ao desmame. Não houve efeito dos tratamentos sobre o intervalo desmame-cio das fêmeas suínas. Proteína total e triglicérides do leite não diferiram entre si, porém, houve diferença na composição em função dos dias pós-parto. As rações não influenciaram significativamente os valores médios do perfil de ácidos graxos do leite de porcas, nem as variáveis econômicas avaliadas. A substituição de até 50% da metionina digestível por betaína em dietas de porcas (84º dia de gestação até o 21º dia de lactação) não causou efeitos negativos sobre os parâmetros produtivos.

ABSTRACT The aim of this study was to evaluate the inclusion of betaine in the diet of sows in the last third of gestation and during lactation, on reproductive performance, composition of the milk, and economic evaluation. A total of 72 sows were used, 36 in the first reproductive cycle (171.77 ± 7.54 kg) and 36 in the second cycle (203.17 ± 13.31 kg), distributed over a randomized-block design, in a 2 x 3 factorial scheme of two reproductive cycles and three diets (R0: control diet, R1: diet with the inclusion of 0.2% betaine and a reduction of 50% in digestible methionine requirement, R2: control diet supplemented with 0.2% betaine). The addition of betaine to the diets had no effect on weight at birth, weight of the sows at weaning, or average weight of the piglets at birth and at weaning, although piglets from sows in their second cycle displayed a higher weight at birth and weaning. There was no effect from the treatments on the interval between weaning and oestrus in the sows. Total protein and triglycerides in the milk did not differ; there were however differences in composition for days post-partum. The diets did not significantly affect average values for the fatty acid profile of the sow milk, or the economic variables. Replacing up to 50% of the digestible methionine with betaine in the sows' diet (day 84 of gestation to day 21 of lactation) had no negative effects on the production parameters.

Resumo O objetivo deste estudo foi estimar a prevalência de excesso de peso e verificar a associação com fatores sociodemográficos, nível de atividade física, hipercolesterolemia e diabetes em servidores universitários do Paraná, Brasil. A pesquisa foi realizada com 339 servidores públicos com idade acima de 18 anos. O excesso de peso foi avaliado por meio do Índice de Massa Corporal, autorelatado. O nível de atividade física foi avaliado por meio de questionário. Os dados sociodemográficos (sexo, idade, nível econômico, escolaridade, situação conjugal e jornada de trabalho) e as doenças crônicas (hipercolesterolemia e diabetes) foram avaliados por autorrelato. Para a associação entre o excesso de peso e as demais variáveis foi utilizada a regressão logística binária. A prevalência de excesso de peso foi de 50,6%. Os grupos mais suscetíveis ao excesso de peso foram: sexo masculino (OR: 2,04; IC: 1,30-3,22), escolaridade menor que 12 anos (OR: 2,46; IC: 1,43-4,23), insuficientemente ativos (OR: 1,64; IC: 1,03-2,60) e os que tinham hipercolesterolemia (OR: 2,28; IC: 1,32-3,96). Conclui-se que mais da metade da amostra estava com excesso de peso. Os fatores associados ao excesso de peso foram o sexo masculino, escolaridade menor que 12 anos, prática insuficiente de atividade física e hipercolesterolemia.

Abstract This study aimed to estimate the prevalence of overweight and investigate its association with sociodemographic factors, physical activity level, hypercholesterolemia, and diabetes in civil servants of a university in the state of Paraná, Brazil. The research was conducted with 339 civil servants aged above 18 years. Overweight was analyzed by self-reported body mass index. Physical activity level was evaluated using a questionnaire. Sociodemographic data (sex, age, economic status, educational level, marital status, and working hours) and information on the chronic diseases of interest (hypercholesterolemia and diabetes) were obtained from self-report. The association between overweight and the other variables was investigated using binary logistic regression. The prevalence of overweight was 50.6%. The groups most susceptible to overweight were: male civil servants (OR: 2.04; CI: 1.30-3.22), those less than 12 years of education (OR: 2.46; IC: 1.43-4.23), who were insufficiently active (OR: 1.64; CI: 1.03-2.60), and those with hypercholesterolemia (OR: 2.28; CI: 1.32-3.96). This study concluded that more than a half of the sample was overweight and that this condition was associated with male sex, educational level below 12 years, insufficient physical activity, and hypercholesterolemia.

RESUMO Objetivo: Analisar a incidência de lesões na coluna vertebral entre 2000 e 2010 devido a acidente motociclístico e sua relação com o aumento da venda de motos nesse período, assim como a distribuição anatômica dessas lesões na coluna. Métodos: Trata-se de estudo retrospectivo, no qual foram coletados dados de 1.295 prontuários de pacientes que sofreram lesão da coluna decorrente de acidente motociclístico internados na enfermaria de TRM (Trauma Raquimedular) do Hospital Geral do Estado da Bahia no período de 2000 a 2010. Foram selecionados 110 prontuários e catalogadas as informações com relação ao sexo, idade, déficit neurológico na apresentação (de acordo com a escala de Frankel), diagnóstico e nível da lesão. Resultados: Entre os anos de 2000 e 2010 houve um aumento de quase cinco vezes na incidência de pacientes que sofreram lesão da coluna devido a acidente motociclístico. Mais da metade (51,4%) apresentou lesão na coluna cervical, 37,2% na torácica e 11,4% na lombar. Somente 34,3% dos pacientes não tinham déficit neurológico na admissão e pacientes com fratura da coluna torácica tiveram maior incidência e gravidade de lesão medular. A média de idade dos pacientes foi de 30 anos. Conclusões: O aumento da incidência de lesões na coluna devido acidente motociclístico ocorreu no mesmo período em que houve aumento das vendas de motos no país. Os pacientes que sofreram essas lesões eram jovens, com incidência maior nos níveis cervical e torácico e altos índices de déficit neurológico.

ABSTRACT Objective: To analyze the incidence of spinal injuries between 2000-2010 due to motorcycle accidents and the relation to the increase in motorcycle sales in the same period, as well as the anatomical distribution of these spinal injuries. Methods: Data were collected from 1,295 records of patients who have suffered spinal injury resulting from motorcycle accidents admitted to the ward TRM (Spinal Cord Trauma) of the Hospital Geral do Estado da Bahia from 2000 to 2010 in this retrospective study. We selected 110 medical records and collected information on sex, age, neurological deficit on admission (according to Frankel scale), diagnosis, and level of injury. Results: Between 2000 and 2010 there was an increase of almost five times in the incidence of patients who have suffered spinal injury due to motorcycle accidents. More than half (51.4%) had cervical spine injury, 37.2% thoracic spine injury and 11.34% had lumbar spine injury. Only 34.3% of patients had no neurological deficit on admission and patients with thoracic spine fracture had a higher incidence and severity of lesion. The average age of patients was 30 years. Conclusions: The increased incidence of spinal injuries due motorcycle accidents occurred in the same period in which there was an increase in motorcycle sales in the country. Patients who have suffered those injuries were young, with higher incidence in the cervical and thoracic spinal levels and high rates of neurological deficit.

RESUMEN Objetivo: Analizar la incidencia de lesiones de la columna entre 2000-2010 debido a los accidentes de motocicleta y su relación con el aumento de las ventas de motocicletas en ese período, y la distribución anatómica de las lesiones de la columna vertebral. Métodos: Estudio retrospectivo en el que se recogieron datos de 1.295 registros de pacientes que han sufrido lesiones de la columna resultantes de accidentes de motocicleta ingresados en la sala de hospital TRM (Trauma de la Médula Espinal) del Hospital Geral do Estado da Bahia entre 2000 y 2010.Se seleccionaron 110 historiales médicos y se recogió información sobre el sexo, edad, déficit neurológico al ingreso (según la escala de Frankel), el diagnóstico y el nivel de la lesión. Resultados: Entre 2000 y 2010 hubo un aumento de casi cinco veces en la incidencia de pacientes que han sufrido lesiones de la columna debido a los accidentes de motocicleta. Más de la mitad (51,4%) tuvo lesiones de la columna cervical, el 37,2% tenían lesión en la columna torácica y el 11,4%, en la lumbar. Sólo el 34,3% de los pacientes no tuvieron déficit neurológico al ingreso y los pacientes con fractura de la columna torácica tuvieron una mayor incidencia y severidad de la lesión de la médula espinal. La edad promedio de los pacientes fue 30 años. Conclusiones: El aumento de la incidencia de lesiones en la columna debido a los accidentes de motocicleta se produjo en el mismo período en que hubo un aumento en las ventas de motocicletas en el país. Los pacientes que han sufrido esas lesiones eran jóvenes, con mayor incidencia en los niveles cervicales y torácicos y altas tasas de déficit neurológico.
