ABSTRACT

INTRODUCCIÓN. El distrés psicológico es un conjunto de síntomas ocasionados por un estrés continuo y progresivo. La pandemia de la enfermedad por coronavirus 2019 llevó al gobierno de Ecuador a tomar medidas para evitar el contagio. Se adoptó el teletrabajo como opción para continuar con la actividad laboral. OBJETIVO. Determinar la prevalencia del distrés psicológico asociado a las condiciones de trabajo en personal que labora en modalidad presencial y teletrabajo. MATERIALES Y MÉTODOS. Estudio observacional transversal. Población y muestra conocida de 81 trabajadores; grupo control de 43 administrativos y grupo de estudio de 38 personal de ventas, de una empresa dedicada a la venta de insumos médicos que laboraron en modalidad presencial y teletrabajo, en el periodo marzo a diciembre de 2020. RESULTADOS. La variable entre los dos grupos estudiados fue teletrabajo con una p< 0,01 con el personal de ventas en un 89,47% (34; 38) y los administrativos en un 60,47% (26; 43). Para determinar si el personal tuvo distrés psicológico se utilizó el cuestionario general de salud de Goldberg de 12 ítems con punto de corte > 3 puntos obteniendo una prevalencia de distrés psicológico en el personal de ventas de 89,47% y en administrativos de 86,05%; además una prevalencia mayor en mujeres 93,02% que en hombres del 81,58%. CONCLUSIÓN. No existió una diferencia estadísticamente significativa, lo que da a entender que hay otros factores no evaluados que generan distrés psicológico, se debe tomar en cuenta para realizar más estudios con una población mayor.


INTRODUCTION. Psychological distress is a set of symptoms caused by continuous and progressive stress. The 2019 coronavirus disease pandemic led the Ecuadorian government to take measures to prevent contagion. Teleworking was adopted as an option to continue with the work activity. OBJECTIVE. To determine the prevalence of psychological distress associated with working conditions in personnel who work in person and telework. MATERIALS AND METHODS. Cross-sectional observational study. Population and known sample of 81 workers; control group of 43 administrative and study group of 38 sales personnel, from a company dedicated to the sale of medical supplies who worked in person and telework, from March to December 2020. RESULTS. The variable between the two groups studied was teleworking with a p<0,01 with sales staff in 89,47% (34; 38) and administrative staff in 60,47% (26; 43). To determine whether the staff had psychological distress, the 12-item Goldberg general health questionnaire with a cut-off point > 3 points was used, obtaining a prevalence of psychological distress in sales staff of 89,47% and in administrative staff of 86,05%; also, a higher prevalence in women 93,02% than in men 81,58%. CONCLUSION. There was no statistically significant difference, which suggests that there are other factors not evaluated that generate psychological distress, which should be considered to carry out more studies with a larger population.

ABSTRACT

ABSTRACT Objective: To investigate the possible relationship between early admission to the school of children in early childhood and oral health conditions (OH) and nutritional status (NS). Material and Methods: Cross-sectional study conducted with 140 children aged 3-4 years, selected for convenience, in 4 public schools in the city of São Paulo, Brazil, during 2016, divided into children with early (IE) and late (IL) admission at school. Comparisons between groups were performed for the presence of overweight / obesity (OW / OB), caries lesions (CL), malocclusion (MO) and dental biofilm (DB), in addition to socioeconomic and dietary data. Multiple regression analysis was applied to determine the association between age of admission at school and OH and NS. Results: Children with IE had CL = 28.1%; DB = 46.9%; MO = 54.7% and OW / OB = 25.9%. Children with IE had IL = 29.8%; DB = 35.1%; MO = 61.4% and OW / OB = 30.8%. No significant association was found between age of admission at school and CL: 1.40 (0.53-3.73) 0.490; DB: 0.51 (0.22-1.16) 0.112; MO: 1.77 (0.77-4.05) 0.173 and OW / OB: 1.27 (0.55-2.92) 0.568, [OR (95% CI) p]. Conclusion: The age of admission at school of children in early childhood did not show a significant association with OH and NS.

ABSTRACT

RESUMO: Objetivo: Atualizar achados de estudos observacionais analíticos sobre a associação entre exposição ocupacional a organofosforados e neoplasias hematológicas. Métodos: Revisão sistemática de literatura, incluindo estudos de coorte e caso controle, sem limitação de tempo de publicação, nos idiomas português e inglês. O rastreamento de artigos foi feito no período de junho de 2017 a julho de 2019 nas bases de dados PubMed, MEDLINE, LILACS, Web of Science e Scopus. A avaliação qualitativa de risco de viés foi feita com a Escala Newcastle-Otawa e com o Checklist Downs e Black. Os resultados foram apresentados segundo as recomendações da Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Resultados: Foram elegíveis 17 estudos avaliados como de boa/alta qualidade metodológica. A exposição a diazinon (um coorte), fonofós (um coorte), diclorvós, crotoxifós e fanfur (um caso controle) associou-se à leucemia, enquanto a exposição a organofosforados associou-se aos linfomas (seis caso controle). O risco de linfoma não-Hodgkin foi maior para os indivíduos expostos a diazinon (um caso controle) e malation (três caso controle), em relação aos não expostos. O mieloma múltiplo ocorreu mais comumente em expostos a organofosforados do que entre os não expostos (um caso controle). Conclusão: A exposição ocupacional a organofosforados aumenta o risco de neoplasias hematológicas, sobretudo entre os indivíduos com maior período de exposição. Medidas de monitoramento de trabalhadores e de controle da exposição são recomendadas.


ABSTRACT: Objective: To update findings of observational analytical studies on the association between occupational exposure to organophosphates and hematologic malignancies. Methodology: Systematic literature review, including cohort and case-control studies, without limitation of publication time, in Portuguese and English. The articles were traced from June 2017 to July 2019 in PubMed, MEDLINE, LILACS, Web of Science, and Scopus databases. The qualitative bias risk assessment was performed using the Newcastle-Ottawa Scale and the Downs and Black Checklist. Results were presented according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA). Results: Seventeen studies evaluated as good/high methodological quality were eligible. Exposure to diazinon (1 cohort), phonophos (1 cohort), dichlorvos, crotoxiphos and famphur (1 case control) was associated with leukemia, while exposure to organophosphate was associated to lymphomas (6 case control); the risk of non-Hodgkin's lymphoma was higher in those exposed to diazinon (1 control case) and malathion (3 control case) than non-exposed ones. Multiple myeloma occurred more commonly in organophosphate exposed than in non-exposed individuals (1 case-control). Conclusion: Occupational exposure to organophosphates increases the risk of hematologic malignancies, especially among individuals with longer exposure periods. Worker monitoring and exposure control measures are recommended.

ABSTRACT

OBJECTIVE: We aimed to estimate the overall survival (OS) and conditional survival (CS) in patients diagnosed with oral and oropharyngeal squamous cell carcinoma (SCC) and to determine their survival trends. METHODS: The study included all consecutive patients treated at the A.C. Camargo Cancer Center for oral or oropharyngeal SCC between 2001 and 2012. Data were obtained from the Hospital Cancer Registry. OS and CS were analyzed using the Kaplan-Meier method to evaluate the probability of survival with Cox predictor models. RESULTS: Data of 505 oral and 380 oropharyngeal SCC patients obtained in 2001-2006 and 2007-2012 were analyzed. Most of the oral SCC (59%) and oropharyngeal SCC (90%) patients had stages III-IV SCC. The 5-year OS for patients with oral SCC was 51.7%, with no significant difference between the first and second periods. The CS rates in 2007-2012 were 65% after the first year and 86% up to the fifth year. For oropharyngeal SCC, the 5-year OS rate was 45.0% in the first period. The survival rate increased to 49.1% from 2007 to 2012, with a reduction in the risk of death (HR=0.69;0.52-09.2). The CS estimates from 2007 to 2012 were 59% after the first year and 75% up to the fifth year. CONCLUSION: Survival across the two time periods remained stable for oral SCC but showed a significant increase for oropharyngeal SCC, possibly because of improvements in the patients' response to radiotherapy, such as intensity-modulated radiation therapy, and the use of more accurate diagnostic imaging approaches.

ABSTRACT

ABSTRACT: Introduction: Poor oral hygiene, regular use of mouthwash and absence of visits to the dentist could correspond to potential risk factors for the development of head and neck cancer. Objective: The objective of this study was to determine whether oral hygiene is associated with the occurrence of oral cavity and head and neck cancer in a Brazilian sample. Method: The variables of oral hygiene condition, such as toothbrushing frequency, dental loss, need and use of prosthesis, and regular visit to the dentist in a case-control study were analyzed in patients from five hospitals in the state of São Paulo, Brazil, paired by gender and age, from the multicenter project Genoma do Câncer de Cabeça e Pescoço (GENCAPO). Results: The most frequent malignancies in the 899 patients included were those of the tongue border (11.41%) and tongue base (10.92%). The multivariable statistical analysis found odds ratio values: Brushing once 0.33 (95%CI 0.25 - 0.44); Brushing twice 0.42 (95%CI 0.35 - 0.52); Flossing always 0.19 (95%CI 0.13 - 0.27); Flossing sometimes 0.19 (95%CI 0.15 - 0.24); Bleeding 2.40 (95%CI 1.40 - 4.09); Prosthesis 1.99 (95%CI 1.54 - 2.56); Visiting the dentist 0.29 (95%CI 0.22 - 0.37); Good hygiene 0.21 (95%CI 0.17 - 0.27); Regular hygiene 0.20 (95%CI 0.15 - 0.25); number of missing teeth (6 or more) 3.30 (95%CI 2.67 - 4.08). Conclusion: These data showed that, in the population studied, indicators of good hygiene such as brushing teeth and flossing were protective factors for mouth and head and neck cancer, while bleeding and many missing teeth were risk factors.


RESUMO: Introdução: Má higiene bucal, uso regular de enxaguante bucal e ausência de visitas ao dentista podem corresponder a potenciais fatores de risco para o desenvolvimento de câncer de cabeça e pescoço. Objetivo: Determinar se a higiene bucal está associada à ocorrência de câncer em cavidade oral e cabeça e pescoço em uma amostra brasileira. Método: O estudo caso controle analisou variáveis de higiene bucal, como frequência de escovação, perda dentária, necessidade e uso de prótese e visita regular ao dentista em pacientes de cinco hospitais do estado de São Paulo, pareados por sexo e idade, provenientes do projeto multicêntrico Genoma do Câncer de Cabeça e Pescoço (GENCAPO). Resultados: As neoplasias mais frequentes nos 899 pacientes incluídos foram: bordo de língua (11,41%) e base de língua (10,92%). A análise estatística múltipla encontrou os seguintes valores de odds ratio: escovar uma vez 0,33 (IC95% 0,25 - 0,44); escovar duas vezes 0,42 (IC95% 0,35 - 0,52); uso de fio dental sempre 0,19 (IC95% 0,13 - 0,27); uso de fio dental às vezes 0,19 (IC95% 0,15 - 0,24); sangramento 2,40 (IC95% 1,40 - 4,09); prótese 1,99 (IC95% 1,54 - 2,56), visita ao dentista 0,29 (IC95% 0,22 - 0,37); boa higiene 0,21 (IC95% 0,17 - 0,27); higiene regular 0,20 (IC95% 0,15 - 0,25); e número de dentes ausentes (6 ou mais) 3,30 (IC95% 2,67 - 4,08). Conclusões: Esses dados mostraram que, na população estudada, indicadores de boa higiene, como escovar os dentes e uso do fio dental, foram fatores de proteção para o câncer de boca e cabeça e pescoço, enquanto sangramento e muitos dentes ausentes foram fatores de risco.

ABSTRACT

El accidente cerebrovascular es la tercera causa de muerte y la primera de discapacidad en la Argentina. Los eventos isquémicos constituyen el 80% de los casos. Los accidentes vasculares cerebrales requieren la implementación de protocolos sistematizados que permitan reducir los tiempos en la atención, la morbilidad y mortalidad. En el consenso participaron especialistas de nueve sociedades médicas relacionadas con la atención de pacientes con enfermedad cerebrovascular. Se consensuó un temario separado en capítulos y para la redacción de los mismos se conformaron grupos de trabajo con miembros de diferentes especialidades médicas. Se discutió y acordó para cada tema el nivel de recomendación en base a la mejor evidencia clínica disponible para cada tópico. Se realizó una adaptación al ámbito local de las recomendaciones cuando se consideró necesario. El sistema de la American Heart Association se utilizó para redactar las recomendaciones y su grado de evidencia. La corrección y edición fue realizada por cinco revisores externos, que no participaron en la redacción y con amplia experiencia en enfermedad vascular. Finalizado el documento preliminar, se organizó una reunión general con todos los integrantes de los grupos de trabajo y los revisores para redactar las recomendaciones definitivas. El consenso abarca la atención del paciente con accidente cerebrovascular isquémico en la fase pre-hospitalaria, evaluación inicial en la central de emergencias, terapias de recanalización (trombolisis y/o trombectomía mecánica), craniectomía descompresiva, neuroimágenes y cuidados clínicos en la internación.


Stroke is the third cause of death and the first cause of disability in Argentina. Ischemic events constitute 80% of cases. It requires the implementation of systematized protocols that allow reducing the time of care, morbidity and mortality. Specialists from nine medical societies related to the care of patients with cerebrovascular disease participated in the consensus. A separate agenda was agreed upon in chapters and for the writing of them, work groups were formed with members of different medical specialties. The level of recommendation was discussed and agreed upon for each topic based on the best clinical evidence available for each of them. An adaptation to the local scope of the recommendations was made when it was considered necessary.The American Heart Association system was used to draft the recommendations and their level of evidence. The correction and editing were done by five external reviewers, who did not participate in the writing and with extensive experience in vascular pathology. Once the preliminary document was finalized, a general meeting was held with all the members of the working groups and the reviewers to reach final recommendations. The consensus covers the management of ischemic stroke in the pre-hospital phase, initial evaluation in the emergency center, recanalization therapies (thrombolysis and/ or mechanical thrombectomy), decompressive craniectomy, neuroimaging and clinical care in the hospital.

ABSTRACT

Objectives: To describe the age group, clinical stage at diagnosis, treatment, and survival rates of breast cancer patients treated in a Brazilian specialized Cancer Center. Method: A hospital-based retrospective cohort study is presented herein, on women with breast cancer diagnosed between January 1, 2000 and December 31, 2012. Data were extracted from the Hospital Cancer Registry of the A.C.Camargo Cancer Center. Data on age group, histology of the tumor, TNM classification, clinical stage and treatments were described in absolute and relative frequencies for three periods. Survival curves were estimated with the Kaplan-Meier estimator. Hazard ratio (HR) and 95% confidence interval (95%CI) were calculated for all variables. Results: A total of 5,095 female breast cancer patients were identified, with most stages classified as I and II (60%). The overall survival was 82.7% for the period of 2000­2004, and 89.9% for 2010­2012 (p<0.001). Patients with invasive ductal carcinoma, who were treated with surgery and hormonal therapy, showed a reduction in the risk of death in the most recent period HRadj=0.42 (95%CI 0.34­0.53) (2010­2012). Conclusions: Early stage diagnosis and combined treatment (including HT) are predictive prognostic factors for high survival rates in patients with invasive breast cancer. Specialized cancer centers can provide valuable indications regarding cancer control policies, evaluating overall survival for breast cancer and its associated prognosis.


Objetivos: Descrever as faixas etárias, estadiamento clínico ao diagnóstico, tratamento e sobrevida global das pacientes com câncer de mama tratadas em um centro de câncer brasileiro. Método: Estudo de uma coorte retrospectiva de base hospitalar, com mulheres diagnosticadas de câncer de mama entre 1º de janeiro de 2000 e 31 de dezembro de 2012. Os dados foram extraídos do Registro Hospitalar de Câncer do A. C. Camargo Cancer Center. Faixa etária, tipo histológico, classificação TNM, estadiamento clínico e tratamento foram descritos em frequência absoluta e relativa estratificados em três períodos. As curvas de sobrevida global foram estimadas pelo método de Kaplan-Meier. A Hazard ratio (HR) com intervalo de confiança de 95% foram calculados para todas as variáveis. Resultados: O total de 5.095 pacientes mulheres com câncer de mama foi identificado, a maioria era estágio inicial 60% (I e II). A sobrevida global foi de 82,7% para o período de 2000­2004 e 89,9% para 2010­2012 (p<0,001). Pacientes com carcinoma ductal invasivo que foram tratadas com cirurgia e hormonioterapia, mostraram redução do risco de morte no período mais recente HRaj=0,42 (0,34­0,53 em 2010­2012). Conclusões: Diagnóstico precoce e tratamento combinado (incluindo hormonioterapia) são fatores prognósticos preditivos para altas taxas de sobrevida em pacientes com câncer de mama invasivo. Centros especializados em câncer podem prover informações valiosas sobre as políticas de controle do câncer, avaliando a sobrevida global do câncer de mama e fatores associados ao prognóstico.

ABSTRACT

Summary Objective: This study describes the summary scores of the Short Form-12 (SF-12) questionnaire, according to socio-demographic factors obtained in a probabilistic and representative sample of the Brazilian urban population. Method: Five thousand (5,000) individuals, over the age of 15, were assessed in 16 capital cities, in the five regions of the country. The selection of households was random. Face-to-face approach was applied in the household interviews. The SF-12 questionnaire was used to assess quality of life. Demographic and socioeconomic characteristics were also evaluated: gender, age, marital status, skin color, region of the country and use of the public health service. Results: The mean value (SD) of the SF-12 for the entire population was 49.3 (8.7) for the physical component (PCS-12) and 52.7 (9.7) for the mental component (MCS-12). Statistical differences were found for gender (PCS-12 and MCS-12), age (PCS-12) and working status (PCS-12 and MCS-12). Women, elderly, widowed and unemployed individuals, those with lower income and with complaints in the last seven days showed lower mean values (PCS-12 and MCS-12). Conclusion: From this point forward, we can provide the basis for comparisons with future research that use the SF-12 for quality of life assessment in Brazil. The Brazilian population has a lower degree of quality of life related do the physical component, and the SF-12 is a useful and discriminative instrument for assessing quality of life in different socio-demographic groups.


Resumo Objetivo: Este estudo descreve os escores sumários do questionário Short Form-12 (SF-12), de acordo com os fatores sociodemográficos obtidos em uma amostra probabilística e representativa da população urbana brasileira. Método: Cinco mil (5.000) indivíduos, com idade superior a 15 anos, foram avaliados nas cinco regiões do país, em 16 capitais. A seleção dos domicílios foi aleatória. A coleta de dados foi realizada através de entrevistas domiciliares. O questionário SF-12 foi utilizado para a avaliação de qualidade de vida. Características demográficas e socioeconômicas também foram avaliadas: sexo, idade, estado civil, cor da pele, região do país e uso do serviço público de saúde. Resultados: O valor médio (DP) do SF-12 para a população total foi de 49,3 (8,7) para o componente físico (PCS-12) e 52,7 (9,7) para o componente mental (MCS-12). Foram encontradas diferenças estatísticas para sexo (PCS-12 e MCS-12), idade (PCS-12) e estado laboral (PCS-12 e MCS-12). Mulheres, idosos, viúvos, indivíduos que não estavam trabalhando, pessoas com menor renda e queixas nos últimos sete dias apresentaram valores médios mais baixos (PCS-12 e MCS-12). Conclusão: Os resultados apresentados fornecem bases populacionais para comparações com pesquisas futuras que utilizem o SF-12 para a avaliação da qualidade de vida no Brasil. A população brasileira tem um menor grau de qualidade de vida relacionada ao componente físico, e o SF-12 é um instrumento útil e discriminativo para a avaliação de qualidade de vida em diferentes grupos sociodemográficos.

ABSTRACT

ABSTRACT OBJECTIVE Estimate the prevalence of active tuberculosis and latent tuberculosis infection among the staff that is in contact and the staff that is not in contact with prisoners, and investigate factors associated with latent tuberculosis infection in this population. METHODS Observational cross-sectional study, conducted from 2012 to 2015, in employees of different prison units in the municipality of Franco da Rocha, SP. It consisted of the application of a questionnaire, application and reading of the tuberculin test, sputum smear microscopy, sputum culture, and radiological examination. The association between the qualitative variables was calculated by the Pearson's chi-squared test. The sociodemographic and clinical-epidemiological factors related to the latent tuberculosis infection were evaluated by the logistic regression with the odds ratios (OR) calculation and their respective intervals with 95% of confidence (95%CI). RESULTS A total of 1,059 employees were examined, 657 (62.0%) of prisons, 249 (23.5%) of CASA Foundation units and 153 (14.5%) of custodial and psychiatric treatment hospitals. The tuberculin test was applied and read for 945 (89.2%) professionals. Of these, 797 (84.3%) were contacts of detainees and 148 (15.7%) were not. Among prison staff, the factors associated with latent tuberculosis infection were: contact with detainee (OR = 2.12, 95%CI 1.21-3.71); male gender (OR = 1.97, 95%CI 1.19-3.27); between 30 and 39 years old (OR = 2.98, 95%CI 1.34-6.63), 40 to 49 years old (OR = 4.32, 95%CI 1.94-9.60), and 50 to 59 years old (OR = 3.98, 95%CI 1.68-9.43); nonwhite color or race (OR = 1.89, 95%CI 1.29-2.78); and smoker (OR = 1.64, 95%CI 1.05-2.55). There were no positive test on sputum smear microscopy and culture. Of the 241 (22.8%) professionals who underwent radiological examination, 48 (19.9%) presented alterations of which 11 were suspected of tuberculosis. CONCLUSIONS Prison employees who have direct contact with detainees are 2.12 times more likely to become infected with Mycobacterium tuberculosis in the work environment and consequently to become ill with tuberculosis and should be targeted for disease prevention and control.


RESUMO OBJETIVO Estimar a prevalência de tuberculose ativa e de infecção latente da tuberculose entre funcionários contatos e não contatos de detentos, e investigar fatores associados à infecção latente da tuberculose nesta população. MÉTODOS Estudo observacional do tipo transversal, realizado no período de 2012 a 2015, em funcionários de diferentes unidades prisionais do município de Franco da Rocha, SP. Consistiu na aplicação de um questionário, aplicação e leitura da prova tuberculínica, baciloscopia e cultura dos escarros e exame radiológico. A associação entre as variáveis qualitativas foi calculada pelo teste qui-quadrado de Pearson e os fatores sociodemográficos e clínico-epidemiológicos relacionados à infecção latente da tuberculose foram avaliados pela regressão logística com o cálculo das odds ratios (OR) e seus respectivos intervalos com 95% de confiança (IC95%). RESULTADOS Foram examinados 1.059 funcionários, sendo 657 (62,0%) de penitenciárias, 249 (23,5%) de unidades da Fundação CASA e 153 (14,5%) de hospitais de custódia e tratamento psiquiátrico. Foi aplicada e lida a prova tuberculínica em 945 (89,2%) profissionais. Desses, 797 (84,3%) eram contatos de detentos e 148 (15,7%) não eram. Entre funcionários das penitenciárias, os fatores associados com a infecção latente da tuberculose foram os seguintes: ter contato com detento (OR = 2,12; IC95% 1,21-3,71); ser do sexo masculino (OR = 1,97; IC95% 1,19-3,27); estar na faixa etária entre 30 e 39 anos (OR = 2,98; IC95% 1,34-6,63), 40 a 49 anos (OR = 4,32; IC95% 1,94-9,60) e 50 a 59 anos (OR = 3,98; IC95% 1,68-9,43); ser da cor ou raça não branca (OR = 1,89; IC95% 1,29-2,78); e ser fumante (OR = 1,64; IC95% 1,05-2,55). Não houve exame positivo na baciloscopia e na cultura. Dos 241 (22,8%) profissionais que realizaram o exame radiológico, 48 (19,9%) apresentaram alterações, dos quais 11 eram suspeitos de tuberculose. CONCLUSÕES Os funcionários das penitenciárias que têm contato direto com os detentos têm 2,12 vezes mais chance de se infectar pelo Mycobacterium tuberculosis no âmbito de trabalho e, consequentemente, de adoecer por tuberculose, devendo ser alvos de ações de prevenção e controle da doença.

ABSTRACT

ABSTRACT OBJECTIVES: Study the clinical characteristics of patients diagnosed with Ewing family tumors (EFTs) and survival analysis based on risk criteria and expression of the surface protein known as insulin-like growth factor (IGFR). METHODS: This was a retrospective cohort study based on clinical data from 77 patients diagnosed with EFTs treated by the Department of Pediatric Oncology at the Barretos Cancer Hospital in a period between 2003 and 2012. Biological samples of patients were examined for the presence of the surface receptor IGFR. RESULTS: The overall survival rate (OSR) of patients included in the study was 45% at five years, and EFS was 30% at five years. Metastasis at diagnosis was present in 44.2% of the sample; 88.2% of the sample was male (p < 0.001). The evaluation of the expression of IGFR in biological samples of patients was associated with the variable metastasis at diagnosis (p < 0.001). Worse prognosis was observed in patients with extrapulmonary metastasis (p = 0.009). The local treatment of neoplasia presented better prognosis in patients undergoing local surgical treatment (p < 0.001). CONCLUSIONS: These results showed a higher incidence of metastasis at diagnosis in patients with EFTs treated at the Barretos Cancer Hospital (BCH). Extrapulmonary metastases were a negative prognostic factor in this study. Surgical treatment of the primary tumor was a factor for better prognosis. Strong expression of IGFR was more frequent in patients with metastases at diagnosis, but did not represent a prognostic factor for EFTs.


RESUMO OBJETIVO: Estudar as características clínicas dos pacientes com diagnóstico de tumores da família Ewing (TFEs) e analisar a sobrevida baseada em critérios de risco e expressão da proteína de superfície conhecida como fator de crescimento semelhante à insulina (IGFR). MÉTODOS: Estudo de coorte retrospectivo, com base em dados clínicos de 77 pacientes com diagnóstico de TFEs tratados pelo Departamento de Oncologia Pediátrica do Hospital de Câncer de Barretos entre 2003 e 2012. Amostras biológicas de pacientes foram examinadas quanto à presença do receptor de superfície IGFR. RESULTADOS: Em cinco anos, a taxa de sobrevida global (SG) dos pacientes incluídos no estudo foi de 45% e a taxa de sobrevida livre de eventos (SLE) foi de 30%. Metástases no momento do diagnóstico foram observadas em 44,2% da amostra, sendo que desses, 88,2% eram do sexo masculino (p < 0,001). A avaliação da expressão de IGFR nas amostras biológicas dos pacientes apresentou associação com a variável metástase ao diagnóstico (p < 0,001). Pacientes com metástase extrapulmonar apresentaram pior prognóstico (p = 0,009). A modalidade de tratamento local da neoplasia apresentou melhor prognóstico em pacientes submetidos ao tratamento cirúrgico local (p < 0,001). CONCLUSÃO: Os resultados evidenciaram uma maior incidência de metástase ao diagnóstico nos pacientes com diagnóstico de TFEs tratados no Hospital de Câncer de Barretos. A metástase de localização extrapulmonar foi fator de pior prognóstico no estudo. O tratamento cirúrgico do tumor primário foi fator de melhor prognóstico. A expressão forte de IGFR esteve mais presente nos pacientes com metástase ao diagnóstico, porém não se mostrou como fator prognóstico nos TFEs.

ABSTRACT

OBJECTIVE: As a lifestyle-related disease, social and cultural disparities may influence the features of squamous cell carcinoma of the head and neck in different geographic regions. We describe demographic, clinical, and pathological aspects of squamous cell carcinoma of the head and neck according to the smoking and alcohol consumption habits of patients in a Brazilian cohort. METHODS: We prospectively analyzed the smoking and alcohol consumption habits of 1,633 patients enrolled in five São Paulo hospitals that participated in the Brazilian Head and Neck Genome Project - Gencapo. RESULTS: The patients who smoked and drank were younger, and those who smoked were leaner than the other patients, regardless of alcohol consumption. The non-smokers/non-drinkers were typically elderly white females who had more differentiated oral cavity cancers and fewer first-degree relatives who smoked. The patients who drank presented significantly more frequent nodal metastasis, and those who smoked presented less-differentiated tumors. CONCLUSIONS: The patients with squamous cell carcinoma of the head and neck demonstrated demographic, clinical, and pathological features that were markedly different according to their smoking and drinking habits. A subset of elderly females who had oral cavity cancer and had never smoked or consumed alcohol was notable. Alcohol consumption seemed to be related to nodal metastasis, whereas smoking correlated with the degree of differentiation. .

ABSTRACT

Introduction: The practice of breastfeeding represents multiple benefits to children; however, several studies show thatthere has been a gradual loss of breastfeeding habits in industrialized and developing countries, mainly because the greatdiversity of types of milk. Additionalliy, there was the presence of biological and socio-cultural factors, which influence andmodify this practice and generate a negative impact on the health of the infant population. In Colombia, in 2005, it was reported that the median duration of exclusive breastfeeding was 2.2 months and the median duration was 14.9 months total; likewise, the department of Bolivar reported a median slightly over a month. Objective: To determine the relationship between social and biological factors in the prevalence of exclusive breastfeedinging children under one year of age in Cartagena, Colombia. Materials and methods: Cross-sectional study, the population consisted of the mothers of 23,109 children less than one year of age, the sample was 562 mothers. The probability sampling was stratified by clusters of three locations in the city where every neighborhood was a cluster. After selecting the neighborhood, a simple random sampling was conducted by city blocks. Mothers of children under one year of age were sought in their homes in the city blocks selected. The information was collected through the survey "Breastfeeding and complementary feeding" used by PROFAMILIA, demographic characteristics weredemographic characteristics were also investigated. Results: The median for breastfeeding was 2 months, social factors associated were: not using a feeding bottle (CI: 2.37-5.38), nuclear family membership (CI: 1.29-2.72), not being a mother head of household (CI: 0.27-0.62), and the biologicalfactor showing association was temporary suspension of breastfeeding (CI: 0.23-0.70).


Introducción: La práctica de la lactancia materna representa múltiples beneficios en los niños; sin embargo, diversosestudios muestran que ha existido una pérdida paulatina del hábito de la lactancia en los países industrializados y en vía de desarrollo, debido sobre todo a la gran diversidad de tipos de leche, además de la presencia de factores biológicos y socioculturales que influyen y modifican esta práctica y generan un impacto negativo en la salud de la población infantil. En Colombia, en el año 2005, se informó que la mediana de duración de la lactancia materna exclusiva fue de 2.2 meses y la duración mediana total 14.9 meses; igualmente,el departamento de Bolívar informó un poco más de medio mes. Objetivo: Determinar la relación de los factores sociales y biológicos en la prevalencia de la lactancia materna exclusiva en niños menores de un año en Cartagena.Material y método: Estudio transversal con población constituida por las madres de 23,109 niños menores de un año, la muestra fue 562 madres. El muestreo fue probabilístico estratificado por conglomerados de las tres localidades de la ciudad, donde cada barrio representaba un conglomerado. Una vez seleccionado el barrio se realizó un muestro aleatorio simple por manzanas. En las manzanas que resultaronseleccionadas se buscaron en sus domicilios las madres de los niños menores de un año. La información se recolectó a través de la encuesta «Lactancia y alimentación complementaria ¼ utilizada por PROFAMILIA; también se indagó acercade las características sociodemográficas.Resultados: La mediana de la lactancia fue 2 meses, los factores sociales que se asociaron fueron no usar biberón (IC:2.37-5.38), pertenecer a familia nuclear (IC: 1.29-2.72), no ser madre jefe de hogar (IC: 0.27-0.62), y el factor biológico que mostró asociación fue suspensión temporal de la lactanciamaterna (IC: 0.23-0.70)...

ABSTRACT

Introdução. O Papilomavírus humano (HPV), particularmente o tipo 16, têm sido associado com risco e prognóstico de tumores de cabeça e pescoço. Contudo, o papel do DNA do HPV e resposta sorológica na sobrevida neste grupo de pacientes ainda não está claro. Objetivos. Avaliar o efeito do HPV (resposta sorológica e detecção do DNA no tecido tumoral) na sobrevida de pacientes com carcinoma epidermóide de cabeça e pescoço, considerando-se as distintas localizações anatômicas (cavidade oral, orofaringe, hipofaringe e laringe). Material e métodos. Coorte de 1.475 pacientes com carcinoma epidermóide de cabeça e pescoço, oriundos de dois estudos multicêntricos, diagnosticados entre novembro de 1998 e dezembro de 2008 e acompanhados até 30 de junho de 2009. Detecção de DNA do HPV no tecido tumoral foi feita pela técnica de PCR (Polymerase Chain Reaction) em tecido fresco e material parafinado. Resposta sorológica às proteínas do HPV foi determinada pela técnica Multiplex Luminex. Sobrevida global e específica pela doença foram calculadas pelo método atuarial (tábuas de vida). Curvas de sobrevida de Kaplan-Meier e teste Log-rank para comparação de curvas de sobrevida foram calculados. Hazard ratio (HR) do efeito da infecção pelo HPV nos tumores de cabeça e pescoço e respectivo intervalo com 95 por cento de confiança (IC95 por cento ) foram calculados via modelo de regressão de Cox ajustado pelas variáveis: estudo de origem dos casos, sexo, idade, educação, consumo de tabaco e de álcool, estadiamento do tumor e tratamento, assim como hábitos sexuais para a subcoorte com esta informação. Resultados. Prevalência de DNA do HPV 16 no tecido tumoral foi de 6,7 por cento nos casos recentes (2003-2008) comparado com 1 por cento nos casos iniciais (1998-2002) para a subcoorte de São Paulo. Aumento da soropositividade para HPV 16 E7 nos casos do estudo mais recente (2003-2008) comparado com os casos do estudo inicial (1998-2002) resultou estatisticamente significante. Foi observada pobre concordância entre os resultados de sorologia e DNA do HPV.

ABSTRACT

The aim of this study was to validate the intake of carotenoids, fruits and vegetables estimated by the Food Frequency Questionnaire for Adolescents (FFQA) using the method of triads. Blood samples were collected from 80 elementary school adolescents to assess serum levels of β-carotene. Partial correlation coefficients (r) were calculated between an estimated intake of carotenoids, fruits and vegetables and the serum levels of β-carotene. Validity coefficients were calculated using the method of triads. With the exception of carotenoids, partial r from the food frequency questionnaire (FFQ) were greater than those of the 24-hour recall (24hR). The fruit/vegetable group showed the highest partial r for the FFQ (r = 0.235) and the 24hR (r = 0.137). The highest validity coefficient was obtained for the vegetable group, as assessed by the FFQ (r = 0.873). On average, the validity coefficient values for the FFQ were greater than those obtained for the 24hR or the β-carotene serum levels. The FFQA is an accurate tool for estimating the intake of carotenoids, fruits and vegetables in this population group.


O objetivo do estudo foi validar a ingestão de carotenóides, frutas e hortaliças estimada pelo Questionário de Frequência Alimentar para Adolescentes (QFAA) utilizando o método das tríades. Foram coletadas amostras sanguíneas de 80 adolescentes de uma escola de Ensino Fundamental para análise do b-caroteno plasmático. Coeficientes de correlação (r) parciais foram obtidos entre a ingestão de carotenóides, frutas e hortaliças e o b-caroteno plasmático. Os coeficientes de validade foram estimados a partir do método das tríades. O QFA apresentou valores de r parcial superiores ao recordatório alimentar de 24 horas (R24h), exceto para carotenóides. O grupo das frutas/hortaliças apresentou os maiores valores de r parciais tanto para o questionário de frequência alimentar (QFA) (r = 0,235) quanto para R24h (r = 0,137). O maior coeficiente de validade foi o do grupo de hortaliças avaliado pelo QFA (r = 0,873). Os valores de coeficiente de validade observados para o QFA foram em média superiores aos obtidos para R24h e b-caroteno plasmático. O QFAA é um instrumento com boa acurácia para estimar o consumo de carotenóides, frutas e hortaliças nesse grupo populacional.

ABSTRACT

Neste artigo analisa-se a tendência temporal da prevalência do tabagismo no Brasil, bem como as assimetrias da prevalência de acordo com as regiões do país, a idade, o gênero e o nível socioeconômico da população. Desde o estabelecimento da relação entre tabagismo e câncer de pulmão há 60 anos, o número de tumores malignos com evidências de associação causal com o tabagismo ascendeu a vinte. O declínio da prevalência do tabagismo na população brasileira tem sido constante desde o final da década de 80. Até 2003, foi mais intenso entre os homens. A partir daquele ano, a queda tornou-se mais pronunciada entre as mulheres. As mais altas prevalências de tabagismo encontram-se no Sudeste e Sul, as duas regiões com maiores incidências de neoplasias estritamente relacionadas ao tabaco (cavidade oral, esôfago e pulmão). A exposição ambiental à fumaça do tabaco também foi examinada considerando-se os efeitos para os adultos não fumantes, que apresentam maior risco de tumores de pulmão, laringe e faringe, e entre crianças de pais fumantes, suscetíveis ao risco de hepatoblastoma e leucemia linfocítica aguda. Apesar do incontestável sucesso da política de controle do tabagismo no país, as ações de prevenção devem considerar que as parcelas da população com piores condições socioeconômicas e com baixo nível educacional são as que apresentam taxas mais altas de prevalência de tabagismo. Dentro destes segmentos populacionais os adolescentes representam uma prioridade.

ABSTRACT

Introdução: O prognóstico dos carcinomas epidermóides de laringe é limitado e a taxa de sobrevida em cinco anos é menor que 70 por cento. A relação de características clínicas e epidemiológicas tem sido investigada na sobrevida de pacientes com tumores de laringe, mas pouco se conhece sobre o efeito dos polimorfismos genéticos no prognóstico da doença. Objetivo: Estudar o papel dos polimorfismos genéticos de genes relacionados aos processos de invasão e metástase (MMP1 e MMP3), de inflamação (Interleucina 2, Interleucina 6, LTA) e reparo de DNA (XRCC1) no prognóstico do carcinoma epidermóide de laringe. Material e métodos: Coorte com 170 pacientes com carcinoma epidermóide de laringe, confirmados por exame anátomo-patológico. Os casos tiveram origem em estudo caso-controle conduzido em cinco hospitais de São Paulo, um hospital em Porto Alegre e outro em Goiânia. As informações sobre o status vital dos pacientes foram levantadas dos prontuários médicos e dos bancos de óbitos municipais e estaduais. A extração do DNA das amostras de sangue dos pacientes foi realizada pelo Instituto de Medicina Tropical da USP e a genotipagem dos polimorfismos genéticos pela Fundação Hemocentro de Ribeirão Preto da Faculdade de Medicina da USP.Resultados: Os polimorfismos genéticos estudados (MMP1 1607, MMP1 -519, MMP3 -1171, IL2 -384, IL2 114, IL6 -174, LTA 252 e XRCC1) não apresentaram efeitos com significância estatística na sobrevida global ou específica pela doença quando analisados isoladamente. Para a sobrevida global, o consumo excessivo de álcool, em g/L/dia, reduziu a sobrevida dos pacientes (80-119 g/L/dia: hazard ratio (HR)=4,0 intervalos com 95 por cento de confiança (IC95 por cento)=1,10-14,53:>120 g/L/dia:HR=5,6 IC95 por cento=1,71-18,24). No modelo de Cox múltiplo, quando ajustados pelo polimorfismo genético MMP3 -1171, a sobrevida piorou para esses pacientes (80-119 g/L/dia: HR=4,9 IC95 por cento=1,07-22,91; >120 g/L/dia: HR=6,3 IC95 por cento=1,49-26,84).
