Initial nipple damages in breastfeeding women: analysis of photographic images and clinical associations / Lesiones tempranas del pezón derivadas de la lactancia materna: análisis de imágenes fotográficas y asociaciones clínicas / Lesões mamilares precoces decorrentes da amamentação: análise de imagens fotográficas e associações clínicas

ABSTRACT Objective: to analyze the initial nipple damage degree by breastfeeding practice and to associate findings with clinical manifestations of breastfeeding women. Methods: a retrospective, cross-sectional study with primary data and photographic images database from two randomized clinical trials. Photographic images were analyzed by two independent evaluators using the Nipple Trauma Score. For analysis, the chi-square, Mann-Whitney tests and Kappa coefficient were applied. Results: 115 breastfeeding women and their respective 186 photographic images were analyzed. The degree of agreement of evaluators using the Nipple Trauma Score was 93.6%. The nipple pain score during breastfeeding was moderate and compromised more than 25% of the nipple surface area. Conclusions: assistance to breastfeeding women should prioritize nipple pain intensity instead of the nipple damage size.

RESUMEN Objetivo: analizar el grado de afectación tisular en las lesiones tempranas del pezón resultantes de la lactancia materna y asociar los hallazgos con las manifestaciones clínicas de las mujeres que amamantan. Métodos: estudio retrospectivo, transversal, con datos primarios y banco de imágenes fotográficas de dos ensayos clínicos aleatorizados. Las imágenes fotográficas fueron analizadas por dos evaluadores independientes, utilizando el Nipple Trauma Score. Para el análisis se aplicaron las pruebas de Chi-Cuadrado, Mann-Whitney y coeficiente Kappa. Resultados: se analizaron 115 mujeres lactantes y sus respectivas 186 imágenes fotográficas. El grado de acuerdo de los evaluadores utilizando el Nipple Trauma Score fue del 93,6%. El nivel de dolor en el pezón durante la lactancia es moderado y existe presencia de lesiones del pezón con más del 25% de la superficie del pezón comprometida. Conclusiones: la asistencia a la mujer lactante debe priorizar el nivel de dolor que presenta en detrimento del tamaño de la lesión del pezón.

RESUMO Objetivo: analisar o grau de comprometimento tecidual das lesões mamilares precoces decorrentes da amamentação e associar achados com as manifestações clínicas de mulheres em amamentação. Métodos: estudo retrospectivo, transversal, envolvendo o uso de dados primários e de banco de imagens fotográficas provenientes de dois ensaios clínicos randomizados. Imagens fotográficas foram analisadas por duas avaliadoras independentes a partir do instrumento Nipple Trauma Score.

Dual visual impairment and contrast sensitivity among community-dwelling older adults: a cross-sectional study from the PrevQuedas Brazil trial / Duplo déficit visual e sensibilidade ao contraste em idosos da comunidade: estudo transversal do PrevQuedas Brasil

OBJECTIVE: To investigate the importance of improving visual assessment for community-dwelling older adult fallers. METHODS: Cross-sectional study with eligible older adults (> 60 years old) living in the community and who suffered at least one fall in the last 12 months from the PrevQuedas Brasil clinical trial. Sociodemographic data, information on previous falls, physical and functional assessment (BOMFAQ and FES-I) were collected. We evaluated impairments in visual acuity and contrast sensitivity using the Snellen E chart and low-contrast visual acuity tests, respectively. Dual visual impairment refers to the presence of both impairments. For statistical analysis we compared the participants in relation to the number of falls (single fallers or recurrent fallers) using Chi-square or Fisher's exact test and the significance level was <0.05 for all analyses. RESULTS: Visual acuity, low contrast sensitivity, and dual visual impairment were associated with recurrent falls (OR 1.85); visual impairment was more prevalent among the oldest old. Approximately 90% of the participants reported using glasses, and 63.80% used multifocal lenses. Dual impairment was identified in 143 (20.30%) participants. In multivariate logistic regression, the predictive variables for recurrent falls were low contrast sensitivity (95%CI 1.15­2.47), dual visual impairment (95%CI 1.16­2.83), and self-perceived fall risk (95%CI 1.16­2.46) which was measured using the Falls Efficacy Scale-International. CONCLUSION: Older adults with dual visual impairment are more likely to suffer recurrent falls. Low contrast sensitivity is crucial for fall risk assessment

OBJETIVO: Este estudo investiga a importância de avaliar a visão de idosos caidores na comunidade. METODOLOGIA: Estudo transversal com idosos elegíveis (> 60 anos) residentes na comunidade e que sofreram pelo menos uma queda nos últimos 12 meses do ensaio clínico PrevQuedas Brasil. Foram coletados dados sociodemográficos, informações sobre quedas pregressas, exames físicos e funcionais (BOMFAQ e FES-I). Avaliamos os comprometimentos da acuidade visual e da sensibilidade ao contraste por meio da Tabela E de Snellen e testes de acuidade visual de baixo contraste, respectivamente. O duplo déficit visual refere-se à presença de ambas as deficiências. Para análise estatística comparamos os idosos com relação ao número de quedas (caidores únicos ou caidores recorrentes) usando Qui-quadrado ou Teste exato de Fisher e o nível de significância foi <0.05 para todas as análises. RESULTADOS: Baixa acuidade visual, baixa sensibilidade ao contraste e duplo déficit visual foram associados a quedas recorrentes com odds ratio ­ OR 1,85, frequentemente mais prevalente entre os idosos longevos. Cerca de 90,00% dos idosos relataram usar óculos e 63,80% usavam lentes multifocais. O duplo déficit visual foi identificado em 143 (20,30%) participantes. Nos modelos de regressão logística multivariados, verificamos que as variáveis preditoras para queda recorrente foram a baixa sensibilidade ao contraste (intervalo de confiança ­ IC95% 1,15­2,47), duplo déficit (IC95% 1,16­2,83) e a autopercepção do risco de cair (IC95% 1,16­2,46) medido pela Falls Efficacy Scale-International. CONCLUSÃO: Idosos com baixa sensibilidade ao contraste e duplo déficit visual têm maiores chances de sofrerem múltiplas quedas quando comparados com idosos que possuem apenas baixa acuidade visual. Assim, a baixa sensibilidade ao contraste é essencial na avaliação do risco de quedas dos idosos

Adesão à Terapia Hormonal Adjuvante com Tamoxifeno e Anastrozol utilizando ARMS-12 e MMAS-4 / Adherence to Adjuvant Hormone Therapy with Tamoxifen and Anastrozole using ARMS-12 and MMAS-4 / Adherencia a la Terapia Hormonal Adyuvante con Tamoxifeno y Anastrozol utilizando ARMS-12 y MMAS-4

Introdução: Entre os cânceres de mama, aproximadamente 75% das mulheres são receptores hormonais positivos, sendo estas mais propensas a responderem à hormonioterapia com anastrozol e tamoxifeno. Apesar de eficazes, apresentam taxas significativas de não adesão. Objetivo: Avaliar a adesão à terapia hormonal adjuvante com tamoxifeno e anastrozol em pacientes atendidos nos Ambulatórios da Mastologia e de Quimioterapia do Hospital São Paulo entre os anos de 2019 e 2020. Método: Estudo transversal com 102 mulheres, realizado entre os meses de setembro de 2019 e março de 2020. A adesão à terapia hormonal adjuvante foi avaliada utilizando-se as escalas Morisky Medication Adherence Scale (MMAS-4) e Adherence to Refills and Medications Scale of 12 items (ARMS-12). Resultados: A média de idade foi de 61,5 anos (59,3-63,6). Entre as pacientes, 27,7% faziam uso de tamoxifeno e 72,3% de anastrozol. Relataram desconforto em relação ao uso do medicamento 84,4%, sendo as ondas de calor (42,2%) e as dores articulares (55,9%) os mais frequentes. A escala de ARMS>12 foi pontuada por 79,2%; cerca de 90% das mulheres pontuaram a MMAS-4 até dois pontos, porém não houve diferença significativa entre os tipos de hormônios utilizados para escalas de adesão (p=0,815 e p=0,489). Conclusão: A adesão à hormonioterapia observada foi relativamente baixa, independentemente da endocrinoterapia, podendo essas pacientes estarem em risco de inadequação quanto à resposta clínica

Introduction: Among breast cancers, approximately 75% of women are hormone receptors-positive, and these are more likely to respond to hormone therapy with anastrozole and tamoxifen. Although effective, they have significant rates of non-adherence. Objective: To evaluate adherence to adjuvant hormone therapy with tamoxifen and anastrozole in patients consulted at the Mastology and Chemotherapy Outpatient Clinic of Hospital São Paulo between 2019 and 2020. Method: Cross-sectional study carried out with 102 women between September 2019 and March 2020. Adherence to hormone therapy was evaluated using the Morisky Medication Adherence Scale (MMAS-4) and Adherence to Refills and Medications Scale of 12 items (ARMS-12). Results: The mean age was 61.5 years (59.3-63.6). Among the patients, 27.7% used tamoxifen and 72.3%, anastrozole. 84.4% of them reported discomfort in using the medication, the most frequent were hot flashes (42.2%) and joint pain (55.9%). 79.2% scored the ARMS>12 scale, about 90% of the women scored MMAS-4 up to 2 points, but there was no significant difference between the types of hormones used for adhesion scales (p=0.815 to p=0.489). Conclusion: Adherence to hormone therapy was relatively low, regardless of the hormone used, and these patients may be at risk of inadequate clinical response

Conclusión: La adherencia de la terapia hormonal observada fue relativamente baja, independientemente de la hormona utilizada, y estas mujeres pueden estar en riesgo de respuesta clínica inadecuada

Relationship between physical activity and functional capacity change in aged cohort in São Paulo, Brazil / Relação entre atividade física e mudança na capacidade funcional numa coorte de idosos em São Paulo, Brasil / Relación entre ejercicio físico y cambio en la capacidad funcional en una cohorte de ancianos en São Paulo, Brasil

ABSTRACT Objectives: to evaluate the relationship between leisure-time physical activity and functional capacity change among aged people. Methods: we analyzed data of an aged cohort looking for determinants of functional capacity at follow-up. Baseline data were collected between 2007 and 2008 - average follow-up of 3,5 years. A full multivariate linear regression model was built to evaluate functional capacity at the end of the follow-up, controlling for functional capacity at baseline, sociodemographic, health and behavioral characteristics and amount of leisure-time physical activity in the period. Results: final model showed functional capacity independently correlated with age (p<0.001), body mass (p=0.013) and the number of activities of daily living compromised at baseline (p<0.001). Functional capacity improved with increased physical activity but loss statistical significance after adjustments (p=0.384). Conclusions: functional capacity decreases with increased age, increased loss of functional capacity at baseline and increased body mass. Albeit a non-significant association, leisure-time physical activity appears as an important modifiable factor.

RESUMO Objetivos: avaliar a relação entre atividade física de lazer e mudança de capacidade funcional entre idosos. Métodos: analisamos dados de uma coorte de idosos em busca de determinantes da capacidade funcional no seguimento. Dados da linha de base foram coletados entre 2007 e 2008 - acompanhamento médio de 3,5 anos. Foi construído um modelo de regressão linear multivariado completo para avaliar a capacidade funcional ao final do seguimento, controlando pela capacidade funcional na linha de base, características sociodemográficas, de saúde e comportamentais e quantidade de atividade física no período. Resultados: o modelo final mostrou capacidade funcional independentemente correlacionada com a idade (p<0,001), massa corporal (p=0,013) e número de atividades de vida diária comprometidas na linha de base (p<0,001). Capacidade funcional melhorou com o aumento da atividade física, mas perdeu significância estatística após ajustes (p=0,384). Conclusões: capacidade funcional diminui com o aumento da idade, o aumento da perda da capacidade funcional na linha de base e o aumento da massa corporal. Embora não significativamente associada, a atividade física no lazer aparece como um importante fator modificável.

RESUMEN Objetivos: evaluar la relación entre ejercicio físico de ocio y cambio de capacidad funcional entre ancianos. Métodos: analizamos datos de una cohorte de ancianos en búsqueda de determinantes de la capacidad funcional en el seguimiento. Datos de la línea de base fueron recolectados entre 2007 y 2008 - acompañamiento mediano de 3,5 años. Fue construido un modelo de regresión linear multivariado completo para evaluar la capacidad funcional al fin del seguimiento, controlando por la capacidad funcional en la línea de base, características sociodemográficas, de salud y conductas y cantidad de ejercicio físico en el período.

Capacidad funcional mejoró con el aumento del ejercicio físico, pero perdió significación estadística después de ajustes (p=0,384). Conclusiones: capacidad funcional disminuyó con el aumento de la edad, el aumento de la perdida de la capacidad funcional en la línea de base y el aumento de la masa corporal. Aunque no significativamente relacionado, el ejercicio físico en el ocio aparece como un importante factor cambiable.

Abdominal drain amylase on the first day after pancreatectomy: a predictive factor for pancreatic fistula

SUMMARY OBJECTIVE: To analyze abdominal drain on the first postoperative day and evaluate its predictive nature for the diagnosis of Pancreatic Fistula exclusion, seeking to establish a cutoff point from which lower values demonstrate safety in excluding the possibility of this complication. METHODS: From August 2017 to June 2020, data from 48 patients undergoing pancreatic resection were collected and analyzed from a prospective cohort. The patients were divided into two groups, one group consisting of patients who did not develop PF (Group A), and the other composed of patients who developed PF (Group B). The receiver operation characteristic curve was constructed, and cutoff points were evaluated by calculating sensitivity and specificity. RESULTS: Group A brought 30 patients together (62.5%) and Group B brought 18 patients together (37.5%). The 444 U/L value was the most satisfactory cutoff point for the receiver operation characteristic curve (CI 0.690-0.941), with a sensitivity of 94.4% and a specificity of 60%, thus being able to select 18 of 30 patients who did not succumb to PF. CONCLUSIONS: Abdominal drain on the first postoperative day can be used as a predictive factor in the diagnosis of PF exclusion (CI 0.690-0.941), with the value of 444 U/L being the best performance cutoff point.

Impact of the Training of Professionals from São Paulo Public Health System in Phytotherapy Practice / Impacto da Capacitação de Profissionais da Rede Pública de Saúde de São Paulo na Prática da Fitoterapia

Abstract: Introduction: Following the introduction in 2006 of the National Policy on Integrative and Complementary Practices, and The National Policy on Medicinal Plants and Herbal Medicines, the Municipal Secretariat for the Environment of the City Hall of Sao Paulo initiated the Medicinal Plants Course, later expanded to The Medicinal Plants and Herbal Medicines Course for the training of health professionals. This study aimed to evaluate the impact of the 2014 and 2015 edition of the course "Medicinal Plants and Herbal Medicines" on health professional practices. Methods: An exploratory and descriptive study was conducted with a qualitative-quantitative approach. The quantitative process (Phase I) consisted of a questionnaire being emailed to health professionals who were involved in the course, divided into seven categories: biomedical professional, dental surgeon, nurse, pharmacist, physiotherapist, physician and nutritionist; and, out of 165 questionnaires, 114 responses were received (69.1%). The Qualitative and Quantitative process (Phase II), comprised semi-structured, in-person individual interviews to obtain detailed information on Phytotherapy practices, with 73 health professionals being interviewed, before and after the training, comparing their practices afterwards. Results: The course had a positive impact on the acceptance and application of Phytotherapy by health professionals with a significant increase (p<0.001) in the expansion of activities related to Phytotherapy (herbal tea "meetings", medicinal herb gardens and capacity training), regarding the use of herbal products, such as Matricaria chamomilla (chamomile), Maytenus ilicifolia (espinheira-santa), Valeriana officinalis (valeriana). An increase in the knowledge of Phytotherapy risks was also observed, although there was no increase in the reporting of adverse reactions. The study confirmed the importance of the inclusion of Medicinal Plants and Herbal Medicines Courses as part of undergraduate and postgraduate school, as well as the technical training and continuing education for SUS health professionals. Conclusion: The positive impact found out in almost all evaluated aspects, such as the increase in the knowledge and in the prescription of herbal medicines, confirms the importance of such courses. The results suggest the training promoted a positive impact on the Phytotherapy practice of the Public Health System professionals in São Paulo.

Resumo: Introdução: Após a aprovação da Política Nacional de Práticas Integrativas e Complementares e da Política Nacional de Plantas Medicinais e Fitoterápicos em 2006, a Secretaria Municipal do Verde e do Meio Ambiente de São Paulo iniciou o curso "Plantas Medicinais" que posteriormente foi ampliado para curso "Plantas Medicinais e Fitoterapia", com o propósito de capacitar profissionais de saúde. Este estudo teve como objetivo avaliar o impacto das edições de 2014 e 2015 do curso "Plantas Medicinais e Fitoterapia" nas práticas profissionais. Métodos: Realizou-se estudo exploratório, descritivo, com abordagem quali-quantitativa. No processo quantitativo (fase I), enviou-se um questionário via e-mail para profissionais de saúde egressos do curso, divididos em sete categorias: biomédico, cirurgião-dentista, enfermeiro, farmacêutico, fisioterapeuta, médico e nutricionista. Do total de 165 questionários, 114 foram respondidos (69,1%). No processo qualitativo e quantitativo (fase II), realizaram-se entrevistas semiestruturadas, presenciais e individuais visando obter informações detalhadas da prática fitoterápica. Entrevistaram-se 73 profissionais de saúde a fim de comparar as práticas deles antes e depois da capacitação. Resultados: O curso impactou positivamente a aceitação e a aplicação da fitoterapia pelos profissionais de saúde, com um aumento significativo (p < 0,001) na ampliação de atividades relacionadas à fitoterapia (rodas de "chás", "hortas medicinais" e capacitação). Houve ainda impacto na aplicação de produtos à base de plantas como Matricaria chamomilla (camomila), Maytenus ilicifolia (espinheira-santa) e Valeriana officinalis (valeriana). Verificou-se também aumento no conhecimento dos riscos da fitoterapia, embora sem o respectivo aumento na notificação de reações adversas. O estudo confirmou a importância da inclusão dos cursos em "Plantas Medicinais e Fitoterapia" na graduação e na pós-graduação, bem como da capacitação técnica e educação permanente para profissionais de saúde do SUS. Conclusão: O impacto positivo na quase totalidade dos aspectos avaliados, como o aumento do conhecimento e a prescrição de fitoterápicos, confirma a importância de tais cursos. Os resultados sugerem que a capacitação promoveu impacto positivo na prática fitoterápica dos profissionais da rede pública de saúde de São Paulo.

Burnout and Well-Being Levels of Medical Students: a Cross-Sectional Study / Níveis de Burnout e Bem-Estar de Estudantes de Medicina: um Estudo Transversal

Abstract: Introduction: The presence of chronic stress, caused by the activities and demands of the medical course, can lead to what is called 'burnout', a syndrome characterized by three dimensions: emotional exhaustion, dehumanization (or depersonalization) and reduced professional achievement. Considering the increased incidence of burnout syndrome, anxiety and depression symptoms, suicide attempts and suicide rates among medical students, as a consequence of increasing demands for professional and financial success at the expense of physical and mental health, one understands the importance of studying the subject and proposing measures of prevention and control. The aim of this study was to evaluate and describe the levels of burnout and well-being of medical students at a Brazilian public university. Method: The stress and well-being levels of students from the first to the sixth year for the Medical Course at Universidade Federal de São Paulo were evaluated using MBI-SS and WHOQOL-BREF questionnaires, applied online on the REDCAP platform. Results: A total of 302 students completed the questionnaires. Regarding the MBI-SS, students showed a low value in the emotional exhaustion factor and high levels of professional disbelief and effectiveness, indicating a burnout that ranged from low to moderate. It was also observed that female students showed a greater tendency toward emotional exhaustion when compared to male ones, as well as the fact that students from the 1st and 2nd years showed higher values of professional effectiveness when compared with 3rd and 4th years, with no difference between genders. Based on the answers from WHOQUOL-BREF questionnaire, the students thought they had a good quality of life. Discussion: These results reinforce possible factors that might interfere with the students' quality of life: excessive workload, teaching model based on extensive lectures, lack of stimulation, recognition for their efforts. Conclusion: The medical students evaluated in this study have a good quality of life and show low or moderate burnout levels.

Resumo: Introdução: A presença de estresse crônico, causado pelas atividades e exigências do curso de Medicina, pode levar ao que se chama de burnout, uma síndrome caracterizada por três dimensões: exaustão emocional, desumanização (ou despersonalização) e reduzida realização profissional. Diante do aumento da incidência de síndrome de burnout, sintomas de ansiedade e depressão, tentativas de suicídio e suicídio entre estudantes de Medicina, encarado como consequência de exigências cada vez maiores de alcance de sucesso profissional e financeiro em detrimento da saúde física e mental, entende-se a importância de estudar o assunto e propor medidas de prevenção e controle. Este estudo teve como objetivos avaliar e descrever os níveis de burnout e qualidade de vida dos estudantes de Medicina da Universidade Federal de São Paulo. Método: Foram avaliados os níveis de burnout e qualidade de vida dos alunos do primeiro ao sexto ano do curso de Medicina da Unifesp, a partir dos questionários MBI-SS e Whoqol-Bref, on-line, em plataforma REDCap. Resultados: Um total de 302 estudantes responderam aos questionários completos. Em relação ao MBI-SS, os estudantes apresentaram baixo valor no fator exaustão emocional e altos valores na descrença e eficácia profissional, indicando um burnout entre baixo e moderado. Observou-se também que estudantes do gênero feminino apresentaram maior tendência à exaustão emocional em comparação ao gênero masculino, bem como estudantes do primeiro e segundo anos apresentaram maiores valores de eficácia profissional quando comparados com os do terceiro e quarto anos, sem diferença entre os gêneros. A partir das respostas do Whoqol-Bref, os estudantes consideraram ter boa qualidade de vida. Esses resultados indicam possíveis fatores que podem interferir na qualidade de vida dos estudantes: a carga horária excessiva de atividades, modelo de ensino baseado em aulas expositivas extensas, ausência de estímulo e reconhecimento pelos seus esforços. Conclusão: Os estudantes de Medicina avaliados neste estudo têm boa qualidade de vida e níveis baixos ou moderados de burnout, atentando-se para as diferenças entre anos de curso e características sociodemográficas.

Exposure to violence: associations with psychiatric disorders in Brazilian youth

Objective: The effects of exposure to violent events in adolescence have not been sufficiently studied in middle-income countries such as Brazil. The aims of this study are to investigate the prevalence of psychiatric disorders among 12-year-olds in two neighborhoods with different socioeconomic status (SES) levels in São Paulo and to examine the influence of previous violent events and SES on the prevalence of psychiatric disorders. Methods: Students from nine public schools in two neighborhoods of São Paulo were recruited. Students and parents answered questions about demographic characteristics, SES, urbanicity and violent experiences. All participants completed the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS) to obtain DSM-IV diagnoses. The data were analyzed using weighted logistic regression with neighborhood stratification after adjusting for neighborhood characteristics, gender, SES and previous traumatic events. Results: The sample included 180 individuals, of whom 61.3% were from low SES and 39.3% had experienced a traumatic event. The weighted prevalence of psychiatric disorders was 21.7%. Having experienced a traumatic event and having low SES were associated with having an internalizing (adjusted OR = 5.46; 2.17-13.74) or externalizing disorder (adjusted OR = 4.33; 1.85-10.15). Conclusions: Investment in reducing SES inequalities and preventing violent events during childhood may improve the mental health of youths from low SES backgrounds.

Effectiveness of a web-based intervention in reducing binge drinking among nightclub patrons / Efetividade de uma intervenção digital na diminuição da prática de binge drinking entre frequentadores de baladas

ABSTRACT OBJECTIVE To evaluate the effectiveness of a web-based intervention in reducing binge drinking among nightclub patrons after six months. METHODS We carried out a website survey with probabilistic sample in 31 nightclubs in the city of São Paulo, Brazil, which originated a randomized controlled trial with 1,057 participants. Those classified as problem drinkers (n = 465) using the Alcohol Use Disorders Identification Test were randomized into two study groups - intervention and control. The web-based intervention consisted of exposing the participants to a normative feedback screen about their alcohol consumption, characterizing the risks associated with amount consumed, money spent on drinks, drinking and driving, risk classification of Alcohol Use Disorders Identification Test, and tips to reduce damage. RESULTS There was a significant reduction in the practice of binge drinking in the week estimated at 38% among participants in the intervention group after six months (p < 0.05). However, there was no significant reduction in the outcomes when we analyzed the intervention and control groups and at baseline and after sixth months, simultaneously. CONCLUSIONS We cannot conclude that digital tools reduce the pattern of binge drinking among party goers in São Paulo. More studies are needed with this methodology because of its attractiveness to this type of group, given the privacy and speed that personalized information is transmitted.

RESUMO OBJETIVO Avaliar, após seis meses, a efetividade de uma intervenção digital na diminuição da prática de binge drinking entre frequentadores de baladas. MÉTODOS Foi realizado um inquérito de portal através de uma amostra probabilística em 31 baladas da cidade de São Paulo, a qual originou um ensaio controlado randomizado com 1.057 participantes. Aqueles classificados como uso problemático do álcool (n = 465) através do Alcohol Use Disorders Identification Test foram randomizados em dois grupos de estudo - intervenção e controle. A intervenção digital consistiu em expor os participantes a uma tela de feedback normativo sobre seu consumo de álcool, caracterizando os riscos associados à quantidade consumida, valores gastos com bebidas, beber e dirigir, classificação do risco do Alcohol Use Disorders Identification Test e dicas de redução de danos. RESULTADOS Houve uma redução significativa da prática de binge drinking na semana estimada em 38% entre os participantes do grupo intervenção após seis meses (p < 0,05). Porém, não houve redução significativa nos desfechos quando se analisam os grupos intervenção e controle e os tempos início e seis meses após, simultaneamente.

Aleitamento materno em crianças indígenas de dois municípios da Amazônia Ocidental Brasileira / Breastfeeding in indigenous children from two cities in the West Brazilian Amazon

Resumo Objetivo Analisar o aleitamento materno de crianças indígenas de zero a dois anos e os fatores associados ao desmame. Métodos Estudo transversal realizado com 94 crianças e 91 mulheres indígenas. Os dados foram coletados nos domicílios, com aplicação de um instrumento construído especificamente para o estudo. Para a análise foi utilizada a regressão logística. Resultados Estavam em aleitamento materno 60,6% das crianças. Em menores de seis meses o AME esteve presente em 35% das crianças. A única associação do desmame precoce com as variáveis foi a etnia, em que a chance de desmame precoce entre as etnias Poyanawa, Nawa e Nukini, foi 3,7 vezes maior em relação a etnia Katukina. Conclusão As prevalências de AM encontram-se aquém das recomendações da OMS. Somente a variável etnia mostrou-se associada ao desmame precoce. Esses dados mostram a necessidade de implementações de programas de incentivo ao AM entre os indígenas.

Abstract Objective : To analyze breastfeeding practice among indigenous children aged between zero and two years and the factors associated with ablactation. Methods : Cross-sectional study conducted with 94 indigenous children and 91 indigenous women. Data were collected in households by applying an instrument specifically developed for the study. Logistic regression was used for the analysis. Results : A total of 60.6% of the children were breastfeeding. Exclusive breastfeeding was present in 35% of the children aged under six months. The only association of early ablactation with the variables was the ethnic group, in which the chance of early ablactation among the Poyanawa, Nawa, and Nukini ethnic groups was 3.7 times higher than the Katukinas. Conclusion : The prevalence indices of breastfeeding is below the recommendations of the WHO. Only the variable ethnic group was found to be associated with early ablactation. These data highlight the need to implement programs to promote breastfeeding among indigenous people.

Factors associated with the need for ventilation at birth of neonates weighing >/=; 2, 500 g

OBJECTIVES: Approximately 20-40% of annual global neonatal deaths occur among infants with birthweights ≥2,500 g, and most of these deaths are associated with intrapartum asphyxia in low- and middle-income countries. This study aims to evaluate the peripartum variables associated with the need for resuscitation at birth of neonates weighing ≥2,500 g. METHOD: This case-control retrospective study was performed on data from all public reference maternity units in the state of Ceará, Northeast Brazil, between March 2009 and March 2010. The subjects were singleton neonates without malformations weighing ≥2,500 g, who required positive-pressure ventilation in the delivery room. The controls had a 1-minute Apgar score of ≥8 and did not undergo resuscitation. Variables associated with positive-pressure ventilation in the delivery room were evaluated via conditional multivariate logistic regression. RESULTS: Of the 2,233 live births with birth weights ≥2,500 g, 1-minute Apgar scores ≤7, and no malformations, 402 patients met the inclusion criteria, and they were paired with 402 controls. Risk variables for positive-pressure ventilation at birth were a gestational age <37 weeks (OR: 3.54; 95% CI: 1.14-10.92) and meconium-stained amniotic fluid (8.53; 4.17-17.47). Cervical examination at maternal admission (0.57; 0.38-0.84) and a written follow-up of the labor (0.68; 0.46-0.98) were identified as protective variables. CONCLUSIONS: Significant flaws in obstetric care are associated with the need for positive-pressure ventilation at birth for neonates weighing ≥2,500 g.

Initiation of resuscitation in the delivery room for extremely preterm infants: a profile of neonatal resuscitation instructors

OBJECTIVE: The goal of the present study was to examine the decisions of pediatricians who teach neonatal resuscitation in Brazil, particularly those who start resuscitation in the delivery room for newborns born at 23-26 gestational weeks. METHODS: The present study was a cross-sectional study that used electronic questionnaires (Dec/11-Sep/13) sent to instructors of the Neonatal Resuscitation Program of the Brazilian Society of Pediatrics. The primary outcome was the gestational age at which the respondent said that he/she would initiate positive pressure ventilation in the delivery room. Latent class analysis was used to identify the major profiles of these instructors, and logistic regression was used to identify variables associated with belonging to one of the derived classes. RESULTS: Of 685 instructors, 82% agreed to participate. Two latent classes were identified: ‘pro-resuscitation’ (instructors with a high probability of performing ventilation on infants born at 23-26 weeks) and ‘pro-limitation’ (instructors with a high probability of starting ventilation only for infants born at 25-26 weeks). In the multivariate model, compared with the ‘pro-limitation’ class, ‘pro-resuscitation’ pediatricians were more likely to be board-certified neonatologists and less likely to base their decision on the probability of the infant’s death or on moral/religious considerations. CONCLUSION: The pediatricians in the most aggressive group were more likely to be specialists in neonatology and to use less subjective criteria to make delivery room decisions.

Trends in alcohol and tobacco use among Brazilian students: 1989 to 2010 / Tendência no uso de álcool e tabaco em estudantes brasileiros: 1989-2010

OBJECTIVE To analyze temporal trends of the prevalence of alcohol and tobacco use among Brazilian students. METHODS We analyzed data published between 1989 and 2010 from five epidemiological surveys on students from the 6th to the 12th grade of public schools from the ten largest state capitals of Brazil. The total sample consisted of 104,104 students and data were collected in classrooms. The same collection tool - a World Health Organization self-reporting questionnaire - and sampling and weighting procedures were used in the five surveys. The Chi-square test for trend was used to compare the prevalence from different years. RESULTS The prevalence of alcohol and tobacco use varied among the years and cities studied. Alcohol consumption decreased in the 10 state capitals (p < 0.001) throughout 21 years. Tobacco use also decreased significantly in eight cities (p < 0.001). The highest prevalence of alcohol use was found in the Southeast region in 1993 (72.8%, in Belo Horizonte) and the lowest one in Belem (30.6%) in 2010. The highest past-year prevalence of tobacco use was found in the South region in 1997 (28.0%, in Curitiba) and the lowest one in the Southeast in 2010 (7.8%, in Sao Paulo). CONCLUSIONS The decreasing trend in the prevalence of tobacco and alcohol use among students detected all over the Country can be related to the successful and comprehensive Brazilian antitobacco and antialcohol policies. Despite these results, the past-year prevalence of alcohol consumption in the past year remained high in all Brazilian regions.

OBJETIVO Analisar a tendência temporal da prevalência de uso de álcool e tabaco por estudantes brasileiros. MÉTODOS Foram analisados, entre 1989 e 2010, dados de cinco inquéritos epidemiológicos com estudantes do sexto ano do ensino fundamental ao terceiro do ensino médio, matriculados em escolas públicas nas 10 maiores capitais do Brasil. A amostra foi de 104.104 estudantes e os dados foram coletados em sala de aula. O instrumento de coleta - questionário de autopreenchimento da Organização Mundial da Saúde - e os procedimentos de amostragem e ponderação foram os mesmos nos cinco inquéritos. Teste de Qui-quadrado de tendências foi utilizado para comparar as prevalências entre os anos. RESULTADOS A prevalência de uso de álcool e tabaco variou nos anos e entre as capitais estudadas. O uso de álcool diminuiu em todas as 10 capitais (p < 0,001), em 21 anos. Houve também diminuição significativa do uso de tabaco em oito capitais (p < 0,001). A maior prevalência de uso de álcool foi observada na região Sudeste, em 1993 (72,8% em Belo Horizonte), e a menor, em Belém (30,6%), em 2010. A maior prevalência de uso do tabaco no último ano foi na região Sul, em 1997 (28,0% em Curitiba) e a menor na região Sudeste, em 2010 (7,8% em São Paulo). CONCLUSÕES A tendência de queda na prevalência de tabagismo e uso de álcool entre estudantes, observada em todo o País, pode estar relacionada com políticas antitabaco e antiálcool bem-sucedidas e abrangentes. Apesar destes resultados, a prevalência de uso de álcool no último ano continuou elevada em todas as regiões brasileiras.

Improving survival in children with AIDS in Brazil: results of the second national study, 1999-2002 / Ampliação da sobrevida em crianças com AIDS no Brasil: resultados do segundo estudo nacional de 1999 a 2002

The objective of this study is to characterize survival in children with AIDS diagnosed in Brazil between 1999-2002, compared with the first national study (1983-1998). This national retrospective cohort study examined a representative sample of Brazilian children exposed to HIV from mother-to-child transmission and followed through 2007. The survival probability after 60 months was analyzed by sex, year of birth and death, clinical classification, use of antiretroviral therapy (ART) and prophylaxis for opportunistic diseases. 920 children were included. The survival probability increased: comparing cases diagnosed before 1988 with those diagnosed from 2001-2002 it increased by 3.5-fold (from 25 percent to 86.3 percent). Use of ART, initial clinical classification, and final classification were significant (p < 0.001) predictors of survival. Issues regarding quality of records and care were identified. The results point to the success of the Brazilian policy of providing ART. The improvement of clinical status contributes to quality of life, while indicating challenges, particularly practices to improve long-term care.

Este estudo caracteriza a sobrevida em crianças com AIDS no Brasil entre 1999-2002, contextualizando com o primeiro estudo nacional (1983-1998). Trata-se de coorte histórica, com crianças expostas ao HIV por transmissão vertical e acompanhadas até 2007. A probabilidade de sobrevivência em 60 meses foi analisada segundo sexo, ano de nascimento e de óbito, classificação clínica, uso de terapia antirretroviral (TARV) e de profilaxia para doenças oportunistas. No total, 920 crianças foram incluídas. A probabilidade de sobrevivência foi ampliada 3,5 vezes nos dois períodos avaliados, passando de 25 por cento antes de 1988 para 86,3 por cento no período de 2001-2002. Uso de TARV, classificação clínica inicial e atual/final foram preditores que influíram significativamente (p < 0,001) para a ampliação da sobrevida. Os resultados deste estudo indicam o sucesso da política brasileira para a abordagem das crianças infectadas com HIV. A melhora do estado clínico contribuiu para melhora da qualidade de vida, mas sinaliza-se para a necessidade de incorporação de práticas pautadas na integralidade do cuidado.

The use of immunohistochemistry for diagnosis of prostate cancer

PURPOSE: Atypical glands (ASAP) are diagnosed in 5.0 percent of prostate biopsies, and cancer identification in a rebiopsy is higher than 40.0 percent. The use of antibodies to mark basal cells is currently a common practice, in order to avoid rebiopsies. There has been no reported study that has reviewed characteristics of radical prostatectomies (RPs) when immunohistochemistry (IHC) was necessary for definitive diagnosis. MATERIALS AND METHODS: Out of 4127 biopsies examined from 2004 to 2008, 144 (3.5 percent) were diagnosed with ASAP. IHC was performed using antibody anti-34ßE12 and p63. The results of surgical specimens of 27 patients treated by RP after the diagnosis of prostate cancer (PC) was made using IHC (Group 1) were compared with 1040 patients where IHC was not necessary (Group 2). RESULTS: IHC helped to diagnose PC in 103 patients (71.5 percent). Twenty-seven (26.2 percent) underwent RP. In Group 1, two (7.4 percent) adenocarcinomas were insignificant versus 29 (2.9 percent) for Group 2. Patients from Group 1 were younger (p = 0.039), had lower Gleason scores (GS) (p < 0.001), lower percentage of Gleason pattern 4 (p < 0.001), and smaller tumors (p < 0.001). CONCLUSION: The use of IHC did not lead to diagnosis of insignificant tumors as illustrated by absence of differences in pathological stage or positive surgical margins in men submitted to RP. Therefore, our results suggest that this modality should be routinely used for a borderline biopsy and ASAP cases.

Effects of curcumin in an orthotopic murine bladder tumor model

Cigarette smoking (CS) is the main risk factor for bladder cancer development. There are more than 100 carcinogens present in cigarette smoke. Among the potential mediators of CS-induced alterations is nuclear factor-kappa (NF-êB), which is responsible for the transcription of genes related to cell transformation, tumor promotion, angiogenesis, invasion and metastasis. Curcumin is a polyphenol compound derived from Curcuma longa that suppress cellular transformation, proliferation, invasion, angiogenesis, and metastasis by down regulating NF-êB and its regulated genes. The aim of our study was to assess the effects of curcumin in bladder urothelial carcinoma. We studied the effects of curcumin in vitro and in vivo using the orthotropic syngeneic bladder tumor animal model MB49. Curcumin promotes apoptosis of bladder tumor cells in vitro. In vivo tumors of animals treated with curcumin were significantly smaller as compared to controls. Using immunohistochemistry, we demonstrated a decrease in the expression of Cox-2 by 8 percent and Cyclin D1 by 13 percent in the animals treated with curcumin; both genes regulated by NF-êB and related to cell proliferation. In this study, we showed that curcumin acts in bladder urothelial cancer, possibly dowregulating NF-êB-related genes, and could be an option in the treatment of urothelial neoplasms. The results of our study suggest that further research is warranted to confirm our findings.

Histopathological findings in extended prostate biopsy with PSA ≤ 4 ng/mL

OBJECTIVE: Cancer detection has been reported in up to 27 percent of patients when lowering the PSA cutoff to 2.5 ng/mL. Although this practice could increase the number of biopsies performed, it also could lead to more frequent detection of significant prostate cancers at an organ-confined stage and/or a less aggressive state. This study describes the incidence of malignancy and tumor characteristics in extended prostate biopsies with PSA ≤ 4 ng/mL. MATERIALS AND METHODS: Prostate biopsies from 1081 patients where examined, 275 (25.4 percent) patients had PSA level ≤ 4 ng/mL. RESULTS: Cancer was diagnosed in 32.0 percent and 35.7 percent of patients with PSA ≤ 4 ng/mL and > 4 ng/mL, respectively (p = 0.906). The median Gleason score was 7 independent of PSA > or ≤ 4 ng/mL (p = 0.078). The median number of cores positive for tumor was 4 and 3, respectively, for PSA > 4 ng/mL and PSA ≤ 4 ng/mL (p = 0.627). There was a difference in the total percent of tumors involving all cores, 11 percent and 7 percent for PSA > or ≤ 4 ng/mL (p = 0.042). Fifty-six patients underwent radical prostatectomy, 12 had PSA ¡Ü 4 ng/mL. In both groups, a diagnosis of cancer was accurate with no differences in Gleason score, tumor volume or staging for both groups. CONCLUSION: When PSA is below 4 ng/mL, cancer is detected in a proportion equal to the proportion diagnosed with a PSA > 4 ng/mL, and tumor characteristics are similar between the two groups. Only clinically significant tumors were diagnosed following radical prostatectomy.

Prostate cancer detection at rebiopsy after an initial benign diagnosis: results using sextant extended prostate biopsy

INTRODUCTION: Sextant prostate biopsy remains the standard technique for the detection of prostate cancer. It is well known that after a diagnosis of small acinar proliferation (ASAP) or high grade prostate intraepithelial neoplasia (HGPIN), the possibility of finding cancer is approximately 40 percent and 30 percent, respectively. OBJECTIVE: We aim to analyze follow-up biopsies on patients who initially received a benign diagnosis after exclusion of HGPIN and ASAP. METHODS: From July 2000 to December 2003, 1177 patients were submitted to sextant extended prostate biopsy in our hospital. The mean patient age was 65.5 years old, and the median number of fragments collected at biopsy was 13. HGPIN and ASAP were excluded from our study. We only considered patients who had a diagnosis of benign at the first biopsy and were subjected to rebiopsies up until May 2005 because of a maintained suspicion of cancer. RESULTS: Cancer was initially detected in 524 patients (44.5 percent), and the diagnosis was benign in 415 (35.3 percent). Rebiopsy was indicated for 76 of the latter patients (18.3 percent) because of a persistent suspicion of cancer. Eight cases of adenocarcinoma (10.5 percent) were detected, six (75 percent) at the first rebiopsy. Six patients were submitted to radical prostatectomy, and all tumors were considered clinically significant. CONCLUSION: Our data indicate that in extended prostate biopsy, the first biopsy detects more cancer, and the first, second, and third rebiopsies after an initial benign diagnosis succeed in finding cancer in 7.9 percent (6/55), 5.9 percent (1/15) and 20 percent (1/4) of patients, respectively.
