RESUMO Introdução: Os efeitos provocados pela COVID-19 em longo prazo são desconhecidos. O presente estudo tem como objetivo avaliar os fatores associados com a qualidade de vida relacionada à saúde e os desfechos em longo prazo em sobreviventes à hospitalização por COVID-19 no Brasil. Métodos: Este será um estudo multicêntrico de coorte prospectivo, aninhado em cinco ensaios clínicos randomizados desenhados para avaliar os efeitos dos tratamentos específicos para COVID-19 em mais de 50 centros no Brasil. Pacientes adultos sobreviventes à hospitalização por infecção por SARS-CoV-2 comprovada ou suspeita serão seguidos por um período de 1 ano, por meio de entrevistas telefônicas estruturadas. O desfecho primário é o escore de utilidade para qualidade de vida relacionada à saúde após 1 ano, avaliado segundo o questionário EuroQol-5D3L. Os desfechos secundários incluirão mortalidade por todas as causas, eventos cardiovasculares graves, reospitalizações, retorno ao trabalho ou estudo, condição funcional física avaliada pelo instrumento Lawton-Brody Instrumental Activities of Daily Living, dispneia avaliada segundo a escala de dispneia modificada do Medical Research Council, necessidade de suporte ventilatório em longo prazo, sintomas de ansiedade e depressão avaliados segundo a Hospital Anxiety and Depression Scale, sintomas de transtorno de estresse pós-traumático avaliados pela ferramenta Impact of Event Scale-Revised e autoavaliação da condição de saúde, conforme a Escala Visual Analógica do EuroQol-5D3L. Serão utilizadas equações de estimativas generalizada para testar a associação entre cinco conjuntos de variáveis (1 - características demográficas, 2 - condição de saúde pré-morbidade, 3 - características da doença aguda, 4 - terapias específicas para COVID-19 recebidas e 5 - variáveis pós-alta atualizadas) e desfechos. Ética e disseminação: O protocolo do estudo foi aprovado pelos Comitês de Ética em Pesquisa de todas as instituições participantes. Os resultados serão disseminados por meio de conferências e periódicos revisados por pares. Abstract Introduction: The long-term effects caused by COVID-19 are unknown. The present study aims to assess factors associated with health-related quality of life and long-term outcomes among survivors of hospitalization for COVID-19 in Brazil. Methods: This is a multicenter prospective cohort study nested in five randomized clinical trials designed to assess the effects of specific COVID-19 treatments in over 50 centers in Brazil. Adult survivors of hospitalization due to proven or suspected SARS-CoV-2 infection will be followed-up for a period of 1 year by means of structured telephone interviews. The primary outcome is the 1-year utility score of health-related quality of life assessed by the EuroQol-5D3L. Secondary outcomes include all-cause mortality, major cardiovascular events, rehospitalizations, return to work or study, physical functional status assessed by the Lawton-Brody Instrumental Activities of Daily Living, dyspnea assessed by the modified Medical Research Council dyspnea scale, need for long-term ventilatory support, symptoms of anxiety and depression assessed by the Hospital Anxiety and Depression Scale, symptoms of posttraumatic stress disorder assessed by the Impact of Event Scale-Revised, and self-rated health assessed by the EuroQol-5D3L Visual Analog Scale. Generalized estimated equations will be performed to test the association between five sets of variables (1- demographic characteristics, 2- premorbid state of health, 3- characteristics of acute illness, 4- specific COVID-19 treatments received, and 5- time-updated postdischarge variables) and outcomes. Ethics and dissemination: The study protocol was approved by the Research Ethics Committee of all participant institutions. The results will be disseminated through conferences and peer-reviewed journals.

RESUMO Objetivo: Avaliar a prevalência de incapacidades físicas, cognitivas e psiquiátricas, fatores associados e sua relação com qualidade de vida em pacientes sobreviventes de internação em unidades de terapia intensiva brasileiras. Métodos: Um estudo de coorte prospectivo multicêntrico está sendo conduzido em dez unidades de terapia intensiva adulto clínico-cirúrgicas representativas das cinco regiões geopolíticas do Brasil. Pacientes com idade ≥ 18 anos que receberam alta das unidades de terapia intensiva participantes e permaneceram internados na unidade de terapia intensiva por 72 horas ou mais, nos casos de internação clínica ou cirúrgica de urgência, e por 120 horas ou mais, nos casos de internação cirúrgica eletiva, serão incluídos de forma consecutiva. Estes pacientes serão seguidos por 1 ano, por meio de entrevistas telefônicas estruturadas 3, 6 e 12 meses pós-alta da unidade de terapia intensiva. Dependência funcional, disfunção cognitiva, sintomas de ansiedade e depressão, sintomas de estresse pós-traumático, qualidade de vida relacionada à saúde, re-hospitalizações e mortalidade em longo prazo serão avaliados como desfechos. Discussão: O presente estudo tem o potencial de contribuir para o conhecimento a respeito da prevalência e dos fatores associados à síndrome pós-cuidados intensivos na população de pacientes adultos sobreviventes de internação em unidades de terapia intensiva brasileiras. Ademais, a associação entre síndrome pós-cuidados intensivos e qualidade de vida relacionada à saúde poderá ser estabelecida. ABSTRACT Objective: To establish the prevalence of physical, cognitive and psychiatric disabilities, associated factors and their relationship with the qualities of life of intensive care survivors in Brazil. Methods: A prospective multicenter cohort study is currently being conducted at 10 adult medical-surgical intensive care units representative of the 5 Brazilian geopolitical regions. Patients aged ≥ 18 years who are discharged from the participating intensive care units and stay 72 hours or more in the intensive care unit for medical or emergency surgery admissions or 120 hours or more for elective surgery admissions are consecutively included. Patients are followed up for a period of one year by means of structured telephone interviews conducted at 3, 6 and 12 months after discharge from the intensive care unit. The outcomes are functional dependence, cognitive dysfunction, anxiety and depression symptoms, posttraumatic stress symptoms, health-related quality of life, rehospitalization and long-term mortality. Discussion: The present study has the potential to contribute to current knowledge of the prevalence and factors associated with postintensive care syndrome among adult intensive care survivors in Brazil. In addition, an association might be established between postintensive care syndrome and health-related quality of life.

O câncer de colo uterino é responsável pela morte de cerca de meio milhão de indivíduos anualmente e é a segunda causa de óbitos por neoplasia entre as mulheres. Apesar destes números elevados, este é um tipo de câncer altamente prevenível e que deveria estar sob controle. O câncer de colo uterino é prevenível por dois fatores: é possível de ser rastreado em suas fases pré-malignas e possui um agente específico, o papilomavírus (HPV), que pode ser evitado.

Colposcopia - Abstract
A colposcopia, apresentada pelo médico alemão Hans Hinselmann, em 1925, permaneceu por vários anos estagnada, em vista das restrições alemães no pós-guerra. Na década de 60, a colposcopia retoma sua difusão principalmente pela necessidade de um exame complementar ao rastreamento citológico. Inúmeras nomenclaturas passaram a ser utilizadas, dificultando o estudo da técnica. Índices colposcópicos procuravam prever o resultado histológico através da pontuação dos achados colposcópicos, mas não tiveram reconhecimento e aplicação difundida. Numa tentativa de unificar a descrição colposcópica, a Federação Internacional de Patologia Cervical e Colposcopia apresentou, em 1975, 1990 e 2002 novas classificações colposcópicas internacionais. A colposcopia assumiu na atualidade um papel intermediário entre citologia e histologia. Entretanto, autores têm mostrado sensibilidade elevada da colposcopia, sugerindo que esta seja empregada como método de rastreio de patologia cervical, mas sua especificidade tem sido questionada. A nova nomenclatura de 2002 procura apresentar mais detalhadamente quais achadoscolposcópicos estão associados à normalidade, lesões de baixo grau, alto grau ou carcinoma, procurando melhorar a descrição colposcópica. Mas como será o desempenho da colposcopia com esta classificação? Até o momento, nenhum estudo científico abordou a nova Classificação Internacional, analisando-a em termos de sensibilidade, especificidade e valores preditivos dos achados colposcópicos.

Objetivo: Avaliar a acurácia da colposcopia utilizando a Classificação Colposcópica Internacional de 2002. Métodos: 3040 pacientes de população geral foram rastreadas para patologia cervical através de exame citopatológico, captura híbrida para HPV de alto risco e inspeção cervical. As colposcopias que resultaram em biópsia (n=468) executadas no rastreamento e acompanhamento destas pacientes foram gravadas, revistas por dois colposcopistas cegados e incluídas para análise. Resultados: Os observadores apresentaram excelente concordância (Kappa=0.843) no relato dos achados pela nova nomenclatura. A colposcopia apresentou sensibilidade de 86% e especificidade de 30.3% em diferenciar colo normal de colo anormal (LSIL, HSIL ou carcinoma); quando a colposcopia objetivava diferenciar colo normal ou LSIL de HSIL ou carcinoma, apresentou sensibilidade de 61.1% e especificidade de 94.4%. Os achados colposcópicos classificados como “maiores” pela nova classificação apresentaram valores preditivos positivos elevados para HSIL. Presença do achado colposcópico na zona de transformação e tamanho da lesão estavam associados a HSIL. Bordas externas definidas, associação de múltiplos achados distintos e presença de zona iodo negativa não estavam relacionados à gravidade das lesões. Conclusão: A colposcopia utilizando a Classificação Internacional de 2002 mostra-se um bom método de rastreamento, mas como método diagnóstico apresenta falhas, não podendo substituir a avaliação histológica. A categorização em achados colposcópicos “maiores” e “menores” apresentada pela nova classificação é adequada. Na realização da colposcopia, é importante também que a lesão seja situada em relação à zona de transformação e que seu tamanho seja indicado, já que estes foram fatores associados a lesões de alto grau. Objectives: To evaluate the colposcopic accuracy according to 2002 International Colposcopic Classification. Methods: 3,040 women from the general population were screened for cervical pathology by Pap smear, high risk HPV Hybrid Capture and naked eye visual inspection. All colposcopic exams that needed biopsy (n=468) performed during screening or follow-up were recorded, reviewed by two blinded colposcopists and included for analysis. Results: The two observers showed excellent agreement (Kappa=0.843) on reporting colposcopic findings according to the new classification. Colposcopy had sensitivity of 86% and specificity of 30.3% when the objective was to distinguish normal cervix from abnormal (LSIL, HSIL or carcinoma); for distinguishing normal cervix or LSIL from HSIL or carcinoma, colposcopy had sensitivity of 61.1% and specificity of 94.4%. Colposcopic findings graded as “major changes” had the highest predictive positive values for detecting HSIL or carcinoma. Colposcopic findings at transformation zone and size of lesion were related to HSIL. Sharp outer border, multiple colposcopic findings and iodine negativity were not statically related to severe lesions. Conclusion: Colposcopy using the new International Classification is a considerable screening method, but its value for diagnoses is restricted and it is not possible to substitute histological sampling. Categorization in “major changes” and “minor changes” according to the new classification is appropriate. When performing colposcopy, it is important to describe where is the colposcopic finding, in or outside the transformation zone, and its size, whereas these characteristics were related to high grade lesions.

A infecção pelo HPV é extremamente prevalente e transformou-se em queixa freqüente tanto na prática ginecológica como em outras especialidades, como dermatologia, urologia e proctologia. O objetivo deste trabalho é esclarecer sobre este agente viral. A compreensão de sua importância é fundamental tanto para o controle e erradicação de outras doenças sexualmente transmissíveis, entre as quais a infecção pelo HIV, quanto para o controle do câncer de colo uterino, uma neoplasia freqüente, principalmente em países em desenvolvimento, como é o caso do Brasil. Infection by the human papillomavirus (HPV) is a prevalent case of infection and is frequently the reason for complaints in Gynecology services as well as in those of other branches of specialization, such as Dermatology, Urology, and Proctology. The objective of this study is to contribute to the understanding of this viral agent, which is fundamental for both the control and eradication of other sexually transmitted diseases, including infection by the HIV, and the control of collum cancer, a common neoplasia, especially in developing countries such as Brazil.

OBJETIVO: Comparar duas modalidades de screening de câncer de colo uterino por exame citopatológico (CP) desenvolvidas no Estado do Rio Grande do Sul: uma, sazonal e isolada, promovida pelo Ministério da Saúde em 1998; outra, regular, promovida pela Secretaria da Saúde do Estado do Rio Grande do Sul no período de 1991 a 1996. MATERIAIS E MÉTODOS: avaliou-se retrospectivamente os resultados obtidos com a coleta de exames citopatológicos de colo uterino da campanha do Ministério da Saúde e do programa regular da Secretaria da Saúde do Estado do Rio Grande do Sul RESULTADOS: Comparando-se o percentual de alterações nos exames coletados pela Secretaria da Saúde em 1996 com os exames coletados pelo Ministério da Saúde em 1998, obteve-se, respectivamente: NIC I - 0,55% / 0,29%; NIC II - 0,25% / 0,15%; NIC III - 0,16% / 0,14%; carcinoma - 0,04% / 0,04%. Quanto aos exames coletados pela Secretaria da Saúde no período 1991-1996, 58,64% não eram representativos da junção escamo-colunar (JEC). Sobre estes, somente 13,74% das lesões de alto grau encontravam-se em CPs não representativos da JEC, enquanto 85,22% das lesões de alto grau encontravam-se nos CPs representativos da JEC (1,04% dos resultados ignorados). CONCLUSÕES: A campanha sazonal do Ministério da Saúde no Rio Grande do Sul apresentou desempenho desfavorável quando comparada ao programa regular da Secretaria da Saúde, sugerindo que rastreamentos isolados tenham eficácia menor que rastreamentos planejados e contínuos. O próprio rastreamento regular possui falhas que devem ser corrigidas, como a baixa representatividade da junção escamo-colunar. OBJECTIVE: To compare two modalities of cervical cancer screening using Pap Smear that were carried out in the state of Rio Grande do Sul - Southern Brazil. The first one is a seasonal and isolated campaign that was promoted by the Brazilian Ministry of Health in 1998; the second one is a regular screening program promoted by the Rio Grande do Sul State Department of Health from 1991 to 1996.MATERIAL AND METHODS: We carried out a retrospective study of the results of the two screening campaigns. RESULTS: Comparison of the Pap smear sample alterations verified from 1991 to 1996 by the State Department of Health with the Pap smear sample alterations verified in 1998 by the Ministry of Health allowed for the following data, respectively: CIN 1 - 0.55%/0.29%; CIN 2 - 0.25%/0.15%; CIN 3 - 0.16%/0.14%; carcinoma - 0.04%/0.04%. Out of the samples collected by the State Department of Health, 58.64% were not representative for squamous columnar junction (SCJ), out of which 13.74% of highgrade lesions were not representative for SCJ and 85.22% of high-grade lesions were representative for ECJ (1.04% of results were ignored). CONCLUSIONS: The isolated campaign of the Brazilian Ministry of Health in the state of Rio Grande do Sul presented poorer results when compared to the regular screening program promoted by the Rio Grande do Sul State Department of Health, suggesting, thus, that isolated screening efforts do not offer results that are as good as those of planned and continuous screening programs. However, the regular screening program has faults that need to be corrected, such as that in the reduced number of Pap smear samples representative of squamous columnar junction.

- Abstract
O câncer de colo uterino é responsável pela morte de cerca de meio milhão de indivíduos anualmente e é a segunda causa de óbitos por neoplasia entre as mulheres. Apesar destes números elevados, este é um tipo de câncer altamente prevenível e que deveria estar sob controle. O câncer de colo uterino é prevenível por dois fatores: é possível de ser rastreado em suas fases pré-malignas e possui um agente específico, o papilomavírus (HPV), que pode ser evitado.

Aims: To evaluate the role of hormonal contraceptives as a risk factor of high-risk human papillomavirus (HR-HPV), cervical intraepithelial lesions (CIN) and cervical cancer in our multi-center population-based LAMS (Latin American Screening) study. Methods: A cohort study with >12,000 women from Brazil and Argentina using logistic regression to analyze the covariates of hormonal contraception (HOC - oral, injections, patches, implants, vaginal ring and progesterone intrauterine system) use followed by multivariate modeling for predictors of HR-HPV and CIN2+. Results: HR-HPV infection was a consistent risk factor of high-grade CIN in all three groups of women. The length of HOC use was not significantly related to high-grade squamous intraepithelial lesions (HSIL)+ Pap (p = 0.069), LSIL+ Pap (p = 0.781) or ASCUS+ (p = 0.231). The same was true with the length of HOC use and histology CIN3+ (p = 0.115) and CIN2+ (p = 0.515). Frequently, HOC users have previously shown more HPV-related lesions, as well as lower HPV prevalence if they were current smokers. But HOC use and time of usage were not independent risk factors of either HR-HPV infection or high-grade CIN using multiple logistic regressions. Conclusions: No evidence was found for an association between the use of HOC with an increased risk for HR-HPV infection or high-grade CIN in this cohort. Copyright © 2010 S.

RESUMO Introdução: Os efeitos provocados pela COVID-19 em longo prazo são desconhecidos. O presente estudo tem como objetivo avaliar os fatores associados com a qualidade de vida relacionada à saúde e os desfechos em longo prazo em sobreviventes à hospitalização por COVID-19 no Brasil. Métodos: Este será um estudo multicêntrico de coorte prospectivo, aninhado em cinco ensaios clínicos randomizados desenhados para avaliar os efeitos dos tratamentos específicos para COVID-19 em mais de 50 centros no Brasil. Pacientes adultos sobreviventes à hospitalização por infecção por SARS-CoV-2 comprovada ou suspeita serão seguidos por um período de 1 ano, por meio de entrevistas telefônicas estruturadas. O desfecho primário é o escore de utilidade para qualidade de vida relacionada à saúde após 1 ano, avaliado segundo o questionário EuroQol-5D3L. Os desfechos secundários incluirão mortalidade por todas as causas, eventos cardiovasculares graves, reospitalizações, retorno ao trabalho ou estudo, condição funcional física avaliada pelo instrumento Lawton-Brody Instrumental Activities of Daily Living, dispneia avaliada segundo a escala de dispneia modificada do Medical Research Council, necessidade de suporte ventilatório em longo prazo, sintomas de ansiedade e depressão avaliados segundo a Hospital Anxiety and Depression Scale, sintomas de transtorno de estresse pós-traumático avaliados pela ferramenta Impact of Event Scale-Revised e autoavaliação da condição de saúde, conforme a Escala Visual Analógica do EuroQol-5D3L. Serão utilizadas equações de estimativas generalizada para testar a associação entre cinco conjuntos de variáveis (1 - características demográficas, 2 - condição de saúde pré-morbidade, 3 - características da doença aguda, 4 - terapias específicas para COVID-19 recebidas e 5 - variáveis pós-alta atualizadas) e desfechos. Ética e disseminação: O protocolo do estudo foi aprovado pelos Comitês de Ética em Pesquisa de todas as instituições participantes. Os resultados serão disseminados por meio de conferências e periódicos revisados por pares.

Introdução: O câncer de colo uterino é o quarto câncer mais comum no sexo feminino e um importante problema mundial de saúde pública. Recentemente, o uso de biomarcadores para melhorar a sensibilidade e especificidade do rastreamento e diagnóstico desta patologia passou a ter maior importância. Dentre estes, P16 e Ki67 passaram a ser largamente utilizados em imunohistoquímica de amostras preservadas em parafina. Entretanto, não se sabe qual a influência do tempo e temperatura de armazenamento de amostras previamente cortadas. Objetivo: O presente estudo tem por finalidade avaliar a influência do tempo de preparo e temperatura de armazenamento na imunorreatividade para P16 e Ki67 de cortes de amostras cervicais. Métodos: Amostras de blocos de parafina de câncer de colo uterino foram seccionadas e montadas em lâminas, de maneira seriada, no período de 9, 6, 3, 1 mês e tempo zero, sendo armazenadas em -20°C, 4°C e temperatura ambiente (TA). Todas as amostras então foram processadas ao mesmo tempo por imunohistoquímica para detecção de P16 e Ki67, sendo realizada leitura da mesma região do tumor nas diferentes condições. Resultados: Dos 10 casos de câncer de colo uterino, foram analisadas 75 regiões para P16 e Ki67 nas diferentes condições. A expressão de P16 e Ki67 não variou de maneira significativa ao longo do tempo nas diferentes condições de temperatura de armazenamento. Por exemplo, os cortes de 9 meses apresentaram a seguinte expressão quando armazenados a -20°C, 4°C e TA, respectivamente [mediana (p25-75)]: marcador P16 - 200 (160-300), 200 (180-300) e 200 (170-300), o que não foi estatisticamente diferente do corte em tempo zero, 200 (200-300), P=0,210; marcador Ki 67 - 210 (160-270), 210 (160-270) e 210 (145-270), o que também não foi estatisticamente diferente do corte em tempo zero, 240 (180-270), P=0,651. Conclusão: Não há influência significativa do tempo de preparo e temperatura de armazenamento de lâminas com material já cortado para a realização de imunohistoquímica posteriormente, no período de até 9 meses, para P16 e Ki67. Isto permite que, ao processarmos lâminas para HE e/ou outros marcadores, podemos reservar lâminas para posterior processamento com P16 e Ki67 sem prejuízo à imunorreatividade. Introduction: Cervical cancer is the fourth most common cancer in women and a major public health problem in the world. Recently, the use of biomarkers to improve the sensitivity and specificity of the screening and diagnosis of this pathology has become more important. Among these, P16 and Ki67 became widely used in immunohistochemistry of samples preserved in paraffin. However, the influence of storage time and temperature of previously cut samples is not known. Aim: The aim of this study was to evaluate the influence of preparation time and storage temperature on the immunoreactivity for P16 and Ki67 of cervical specimens. Methods: Cervical cancer paraffin blocks were sectioned and mounted onto glass slides in 9, 6, 3, 1 month and zero time and stored at -20°C, 4°C and room temperature (RT). All slides were then processed at the same time by immunohistochemistry for the detection of P16 and Ki67, and the same tumor region was read under the different conditions. Results: Of the 10 cases of cervical cancer, 75 regions were analyzed for P16 and Ki67 under different conditions. Expression of P16 and Ki67 did not vary significantly over time at different storage temperature conditions. For example, the 9-month slides showed the following expression when stored at -20°C, 4°C and RT, respectively [median (p25-75)]: P16 - 200 (160-300), 200 (180-300) and 200 (170-300), which was not statistically different from zero time cut, 200 (200-300), P = 0.210; Ki 67 - 270 (160-270), 210 (160-270) and 210 (145-270), which was also not statistically different from zero-time cutoff, 240 (180-270), P = 0.651. Conclusion: There is no significant influence of the preparation time and storage temperature of slides of cervical cancer to be processed by immunohistochemistry later, in the period of up to 9 months, for P16 and Ki67. This allows, when processing slides for HE and / or other markers, we can reserve slides for further processing with P16 and Ki67 without impairing immunoreactivity.

Introdução: O câncer de mama tem se mostrado a neoplasia mais incidente entre as mulheres de todo o mundo. Entretanto, percebe-se que a incidência apresenta grande variação geográfica, sugerindo que a ação dos fatores de risco varie acentuadamente entre as diferentes populações. Assim, estudos em determinadas populações sobre os seus fatores determinantes para câncer de mama podem contribuir para melhorar as estratégias de saúde pública, reduzindo sua morbi-mortalidade. Objetivo: Avaliar potenciais fatores de risco para câncer de mama em uma população de Porto Alegre e construir um modelo multivariado com estes fatores para predição de risco de câncer de mama. Delineamento: Estudo de coorte de base populacional. Método: Foram selecionadas 4.242 mulheres com idades entre 40 e 69 anos, sem história pregressa de câncer de mama, em atendimento em unidades básicas de saúde de Porto Alegre, as quais foram submetidas a rastreamento mamográfico. Elas foram avaliadas em relação aos seguintes fatores de risco: raça, tabagismo, etilismo, idade da menarca, idade do nascimento do primeiro filho, número de gestações, idade da última gestação, tempo de amamentação, história de ooforectomia e histerectomia, idade da menopausa, tempo de uso de reposição hormonal, uso de contraceptivo hormonal, histórico de biópsias mamárias, história familiar, peso e altura. A coleta de dados referente aos potenciais fatores de risco para câncer de mama foi realizada em dois momentos distintos, sendo a primeira coleta realizada durante o período de recrutamento das participantes compreendido entre os anos de 2004 e 2006 nas unidades básicas de saúde e a segunda coleta de dados foi realizada no momento em que as participantes compareciam ao centro de referência para a primeira visita de rastreamento mamográfico. As variáveis coletadas em ambos os momentos eram complementares, porém algumas variáveis estavam presentes em ambos os instrumentos de coleta de dados, as quais foram analisadas apenas as variáveis coletadas no segundo momento por serem mais atuais. As variáveis categóricas foram descritas por frequências e percentuais. As variáveis quantitativas com distribuição simétrica foram descritas pela média e o desvio padrão e as variáveis com distribuição assimétrica pela mediana e o intervalo interquartil (percentis 25 e 75). A associação entre câncer de mama e potenciais fatores de risco foi avaliada através de um modelo logístico multivariado. Em todas estas análises, um valor de p abaixo de 0,05 foi considerado estatisticamente significativo e foi analisado e considerado o IC95%. Resultados: Um total de 73 participantes de 4.242 apresentaram diagnóstico de câncer de mama. A análise multivariada considerando todas as pacientes, de 40-69 anos, mostrou que quanto maior a idade (OR=1,08, 95%IC: 1,04-1,12), maior a altura (OR=1,04, 95%IC: 1,00-1,09) e história de biópsia mamária anterior (OR=2,66, 95%IC: 1,38-5,13) estavam associadas a desenvolvimento de câncer de mama. Por outro lado, o número de gestações (OR=0,87, 95%IC: 0,78-0,98) e uso de terapia de reposição hormonal (OR=0,39, 95%IC: 0,20-0,75) foram associados como fator protetor para câncer de mama. Adicionalmente, realizamos análise separando as participantes em grupos de 40-49 anos e 50-69 anos, pois algum fator de risco poderia ter comportamento específico nestas faixas etárias. Nenhum fator de risco adicional foi identificado com esta estratificação etária, sendo que alguns fatores perderam significância estatística. No grupo de 40-49 anos, altura e biópsia mamária anterior mantiveram-se como fatores de risco. No grupo de 50-69, biópsia mamária anterior manteve-se como fator de risco e número de gestações e uso de terapia de reposição hormonal mantiveram-se como fator protetor. Diversas sub-análises não contribuíram para o entendimento como reposição hormonal o qual foi identificado como fator protetor. Conclusão: Em nosso estudo o modelo de predição de risco indica que devem ser avaliadas as seguintes variáveis nesta população específica de 40 a 69 anos: idade, altura, realização de biópsias mamárias anteriores, número de gestações e utilização de terapia de reposição hormonal. Estes achados estão de acordo com a literatura e agregados a outros estudos podem ajudar a compreender melhor o modelo causal de câncer de mama na região sul do Brasil. Introduction: Breast cancer has been the most common cancer among women worldwide. However, it is clear that the incidence has great geographic variation, which suggests that the action of risk factors varies substantially between different populations. Thus, studies on the determining factors for breast cancer in certain populations may contribute to improve public health strategies and reduce morbimortality. Objective: Assess potential risk factors for breast cancer in a population in southern Brazil and build a multivariate model using these factors for breast cancer risk prediction. Methods: 4,242 women aged between 40 and 69 years without a history of breast cancer were selected at primary healthcare facilities in Porto Alegre and submitted to mammographic screening. They were evaluated for the following risk factors: race, smoking, alcohol consumption, age at menarche, age at the birth of first child, number of pregnancies, age at the last pregnancy, duration of breastfeeding, history of oophorectomy and hysterectomy, age at menopause, duration of hormone replacement therapy, use of hormonal contraceptives, history of breast biopsies, family history, weight and height. The collection of data related to potential risk factors for breast cancer was conducted at two different times. The first collection was held during the recruitment of participants from 2004 to 2006 at primary healthcare units and the second data collection was performed at the time the participants went to the reference center for the first mammographic screening visit. The variables collected at both times were complementary, but some variables were present in both data collection instruments, and only the variables collected in the second phase were analyzed because they were more current. Categorical variables were described as frequencies and percentages. Quantitative variables with symmetric distribution were described as the mean and standard deviation, and variables with asymmetrical distribution as median and interquartile range (25th and 75th percentiles). The association between breast cancer and potential risk factors was evaluated using a multivariate logistic model. In all these analyses, a p-value less than 0.05 was considered statistically significant with a 95% CI. Results: A total of 73 participants among 4,242 had a breast cancer diagnosis. The multivariate analysis considering all patients aged 40-69 years showed that older age (OR = 1.08, 95% CI: 1.04-1.12), higher height (OR = 1.04, 95% CI: 1.00-1.09) and history of previous breast biopsy (OR = 2.66, 95% CI: 1.38 - 5.13) were associated with the development of breast cancer. Conversely, the number of pregnancies (OR = 0.87, 95% CI: 0.78-0.98) and use of hormone replacement therapy (OR = 0.39, 95% CI: 0.20 - 0 75) were associated as a protective factor for breast cancer. Additionally, we performed an analysis separating the participants into groups of 40-49 years old and 50-69 years old, since a risk factor could have a specific behavior in these age groups. No additional risk factors were identified within this age bracket, and some factors lost statistical significance. In the 40-49 year old group, height and previous breast biopsy remained as risk factors. In the 50-69 year old group, a previous breast biopsy remained as a risk factor and the number of pregnancies and use of hormone replacement therapy remained as a protective factor. A number of sub-analyses did not help us understand why or how hormone replacement acted as a protective factor. Conclusion: In our study, the risk prediction model indicates that the following variables should be assessed in this specific population from 40 to 69 years old: age, height, having had previous breast biopsies, number of pregnancies, and use of hormone replacement therapy. These findings are consistent with the literature and combined with other studies may help to better understand the causal model of breast cancer in southern Brazil.

- Abstract
Importance: The effectiveness of goal-directed care to reduce loss of brain-dead potential donors to cardiac arrest is unclear., Objective: To evaluate the effectiveness of an evidence-based, goal-directed checklist in the clinical management of brain-dead potential donors in the intensive care unit (ICU)., Design, Setting, and Participants: The Donation Network to Optimize Organ Recovery Study (DONORS) was an open-label, parallel-group cluster randomized clinical trial in Brazil. Enrollment and follow-up were conducted from June 20, 2017, to November 30, 2019. Hospital ICUs that reported 10 or more brain deaths in the previous 2 years were included. Consecutive brain-dead potential donors in the ICU aged 14 to 90 years with a condition consistent with brain death after the first clinical examination were enrolled. Participants were randomized to either the intervention group or the control group. The intention-to-treat data analysis was conducted from June 15 to August 30, 2020., Interventions: Hospital staff in the intervention group were instructed to administer to brain-dead potential donors in the intervention group an evidence-based checklist with 13 clinical goals and 14 corresponding actions to guide care, every 6 hours, from study enrollment to organ retrieval. The control group provided or received usual care., Main Outcomes and Measures: The primary outcome was loss of brain-dead potential donors to cardiac arrest at the individual level. A prespecified sensitivity analysis assessed the effect of adherence to the checklist in the intervention group., Results: Among the 1771 brain-dead potential donors screened in 63 hospitals, 1535 were included. These patients included 673 males (59.2%) and had a median (IQR) age of 51 (36.3-62.0) years. The main cause of brain injury was stroke (877 [57.1%]), followed by trauma (485 [31.6%]). Of the 63 hospitals, 31 (49.2%) were assigned to the intervention group (743 [48.4%] brain-dead potential donors) and 32 (50.8%) to the control group (792 [51.6%] brain-dead potential donors). Seventy potential donors (9.4%) at intervention hospitals and 117 (14.8%) at control hospitals met the primary outcome (risk ratio [RR], 0.70; 95% CI, 0.46-1.08; P = .11). The primary outcome rate was lower in those with adherence higher than 79.0% than in the control group (5.3% vs 14.8%; RR, 0.41; 95% CI, 0.22-0.78; P = .006)., Conclusions and Relevance: This cluster randomized clinical trial was inconclusive in determining whether the overall use of an evidence-based, goal-directed checklist reduced brain-dead potential donor loss to cardiac arrest. The findings suggest that use of such a checklist has limited effectiveness without adherence to the actions recommended in this checklist., Trial Registration: ClinicalTrials.gov Identifier: NCT03179020.

- Abstract
Introduction: The long-term effects caused by COVID-19 are unknown. The present study aims to assess factors associated with health-related quality of life and long-term outcomes among survivors of hospitalization for COVID-19 in Brazil., Methods: This is a multicenter prospective cohort study nested in five randomized clinical trials designed to assess the effects of specific COVID-19 treatments in over 50 centers in Brazil. Adult survivors of hospitalization due to proven or suspected SARS-CoV-2 infection will be followed-up for a period of 1 year by means of structured telephone interviews. The primary outcome is the 1-year utility score of health-related quality of life assessed by the EuroQol-5D3L. Secondary outcomes include all-cause mortality, major cardiovascular events, rehospitalizations, return to work or study, physical functional status assessed by the Lawton-Brody Instrumental Activities of Daily Living, dyspnea assessed by the modified Medical Research Council dyspnea scale, need for long-term ventilatory support, symptoms of anxiety and depression assessed by the Hospital Anxiety and Depression Scale, symptoms of posttraumatic stress disorder assessed by the Impact of Event Scale-Revised, and self-rated health assessed by the EuroQol-5D3L Visual Analog Scale. Generalized estimated equations will be performed to test the association between five sets of variables (1- demographic characteristics, 2- premorbid state of health, 3- characteristics of acute illness, 4- specific COVID-19 treatments received, and 5- time-updated postdischarge variables) and outcomes., Ethics and Dissemination: The study protocol was approved by the Research Ethics Committee of all participant institutions. The results will be disseminated through conferences and peer-reviewed journals.

- Abstract
Importance: The effects of intensive care unit (ICU) visiting hours remain uncertain., Objective: To determine whether a flexible family visitation policy in the ICU reduces the incidence of delirium., Design, Setting and Participants: Cluster-crossover randomized clinical trial involving patients, family members, and clinicians from 36 adult ICUs with restricted visiting hours (<4.5 hours per day) in Brazil. Participants were recruited from April 2017 to June 2018, with follow-up until July 2018., Interventions: Flexible visitation (up to 12 hours per day) supported by family education (n = 837 patients, 652 family members, and 435 clinicians) or usual restricted visitation (median, 1.5 hours per day; n = 848 patients, 643 family members, and 391 clinicians). Nineteen ICUs started with flexible visitation, and 17 started with restricted visitation., Main Outcomes and Measures: Primary outcome was incidence of delirium during ICU stay, assessed using the CAM-ICU. Secondary outcomes included ICU-acquired infections for patients; symptoms of anxiety and depression assessed using the HADS (range, 0 [best] to 21 [worst]) for family members; and burnout for ICU staff (Maslach Burnout Inventory)., Results: Among 1685 patients, 1295 family members, and 826 clinicians enrolled, 1685 patients (100%) (mean age, 58.5 years; 47.2% women), 1060 family members (81.8%) (mean age, 45.2 years; 70.3% women), and 737 clinicians (89.2%) (mean age, 35.5 years; 72.9% women) completed the trial. The mean daily duration of visits was significantly higher with flexible visitation (4.8 vs 1.4 hours; adjusted difference, 3.4 hours [95% CI, 2.8 to 3.9]; P < .001). The incidence of delirium during ICU stay was not significantly different between flexible and restricted visitation (18.9% vs 20.1%; adjusted difference, -1.7% [95% CI, -6.1% to 2.7%]; P = .44). Among 9 prespecified secondary outcomes, 6 did not differ significantly between flexible and restricted visitation, including ICU-acquired infections (3.7% vs 4.5%; adjusted difference, -0.8% [95% CI, -2.1% to 1.0%]; P = .38) and staff burnout (22.0% vs 24.8%; adjusted difference, -3.8% [95% CI, -4.8% to 12.5%]; P = .36). For family members, median anxiety (6.0 vs 7.0; adjusted difference, -1.6 [95% CI, -2.3 to -0.9]; P < .001) and depression scores (4.0 vs 5.0; adjusted difference, -1.2 [95% CI, -2.0 to -0.4]; P = .003) were significantly better with flexible visitation., Conclusions and Relevance: Among patients in the ICU, a flexible family visitation policy, vs standard restricted visiting hours, did not significantly reduce the incidence of delirium., Trial Registration: ClinicalTrials.gov Identifier: NCT02932358.
