Survival trends in gastric cancer in Brazil: real-life data from a large cancer center.

Background: Gastric cancer (GC) is the fourth leading cause of cancer deaths globally. There is a paucity of real-life data on GC in Brazil. Our study aimed to evaluate survival trends in gastric adenocarcinoma (GA) in a large cancer center in Brazil during 2000-2017. Methods: Based on our Hospital Cancer Registry Database, all individuals diagnosed with GA between 2000 and 2017, and treated at A.C. Camargo Cancer Center, were retrospectively included. The primary objectives were to describe the patient demographics, clinicopathological characteristics, treatment modalities and survival trends during four separate periods of diagnosis (2000-2004; 2005-2009; 2010-2014 and 2015-2017). χ2 test was performed between two specified periods (2000-2004 and 2015-2017) to compare categorical variables. Overall survival (OS) curves were stratified by four separate periods and compared with log-rank tests. Results: This analysis included 1,406 individuals. Across all periods, most patients were men aged 50-69 and presented with Lauren's intestinal subtype. The frequency of stage IV disease significantly decreased between 2000-2004 and 2015-2017 (43.6% to 32.8%, p < 0.001). In contrast, we observed a rise in stage II (9.4% to 24.8%, p < 0.001) in the same comparison. We noticed an increased utilization of a combined approach involving chemotherapy and surgery (12% in 2000-2004 and 36.3% in 2015-2017, p < 0.001). The predicted 5-year OS of patients with GA in 2000-2004 was 27.8%, which increased to 53.9% in 2015-2017 (p < 0.001). Conclusion: Our retrospective cohort showed an upward trend in survival rates during the period. We observed that 5-year OS almost doubled among men and women during 2000-2017. Mini Abstract: The present retrospective cohort showed an upward trend in survival rates during the period from 2000 to 2017, in which the OS almost doubled among men and women.

Data quality in Brazilian population-based cancer registries for gastrointestinal cancers.

BACKGROUND: Population-based cancer registries (PBCRs) are the primary source of information for cancer surveillance and monitoring. Currently, there are 30 active PBCRs in Brazil. The objective of this study was to analyze the data quality of five gastrointestinal cancers (esophagus, stomach, colorectal, liver, and pancreas) according to the criteria of comparability, validity, completeness, and timeliness in Brazilian cancer registries. METHODS: This study included data from Brazilian PBCRs with more than ten years of historical data starting in the year 2000, regardless of the type of defined geographical coverage (state, metropolitan region, or capital), totaling 16 registries. Brazilian PBCRs were evaluated based on four international data quality criteria: comparability, validity (accuracy), completeness, and timeliness. All cancer cases were analyzed, except for nonmelanoma skin cancer cases (C44) and five gastrointestinal tumors (esophageal cancer, stomach cancer, colorectal cancer, liver cancer, and pancreatic cancer) per cancer registry and sex, according to the available period. RESULTS: The 16 Brazilian PBCRs represent 17% of the population (36 million inhabitants in 2021) according to data from 2000 to 2018. There was a variation in the incidence in the historical series ranging from 12 to 19 years. The proportion of morphologically verified (MV%) cases varied from 74.3% (Manaus) to 94.8% (Aracaju), and the proportion of incidentally reported death certificate only (DCO%) cases varied from 3.0% (São Paulo) to 23.9% (Espírito Santo). High-lethality malignant neoplasms, such as liver and pancreas, had DCO percentages greater than 30% in most cancer registries. The sixteen registries have more than a 48-month delay in data release compared to the 2022 calendar year. CONCLUSION: The studied Brazilian cancer registries met international comparability criteria; however, half of the registries showed indices below the expected levels for validity and completeness criteria for high-lethality tumors such as liver and pancreas tumors, in addition to a long delay in data availability and disclosure. Significant efforts are necessary to ensure the operational and stability of the PBCR in Brazil, which continues to be a tool for monitoring cancer incidence and assessing national cancer control policies.

Identifying malignant mesothelioma by a pathological survey using the São Paulo state hospital cancer registry, Brazil.

OBJECTIVE: To review the pathological diagnosis of possible cases and/or hidden cases of malignant mesothelioma (MM) between 2000 and 2012 using the Hospital-Based Cancer Registry database in the state of São Paulo, Brazil. METHODS: Possible cases were retrieved by assessing the database. Inclusion criteria were being older than 30 years of age and having ICD-O-3 topography and morphology codes related to MM. A board of expert pathologists reviewed the pathology reports and requested paraffin blocks in cases that demanded revision. After staining with calretinin, D2-40, WT-1 (as positive MM markers) and Ber-EP4 and MOC31 (as negative MM markers), cases were divided and studied independently by a pair of pathologists to confirm or discard the diagnosis of MM. RESULTS: Our sample comprised 482 cases from 25 hospitals, and 130 needed further histological revision. We received 73 paraffin blocks with adequate material. After board analysis, there were 9 cases with a definitive diagnosis of MM, improving the diagnostic rate in 12%. Two cases of previously diagnosed MM were discarded by review. CONCLUSIONS: Our results confirm that part of MM underdiagnosis and underreporting in Brazil is due to incomplete or mistaken pathological diagnosis.

Maternal impacts of a physically disabled baby birth: A comparative study / Impactos maternos do nascimento de um bebê com deficiência física: um estudo comparativo

Objective This study aims to assess the emotional impacts of the baby's physical disability on the mother. Method It is an exploratory investigation carried on with two mother-infant dyads, only one of which gave birth to a physically disabled baby, both participating in a larger case-control investigation. The tools used included the Beck Anxiety and Depression Inventories, the Parental Reflective Functioning Questionnaire, the Ages and Stages Questionnaire as well as semi-structured interviews. Results Both mothers showed similar reports and parenting levels, but the one whose baby had a disability scored higher on anxiety and depression, in connection with the baby's low level of development. Conclusion It is concluded that, in order to achieve the same levels of a typical parenting condition, greater adaptation mechanisms are required.

Objetivo Este artigo tem como objetivo avaliar impactos emocionais da deficiência física do bebê na mãe.

Foram utilizados a Entrevista Semiestruturada, Inventários Beck de Ansiedade e Depressão, Questionário de Função Reflexiva Parental e Ages and Stages Questionnaire. Resultados As mães demonstraram relatos e níveis de parentalidade semelhantes, mas a do bebê com deficiência apresentou maiores scores para ansiedade e depressão, relacionados ao baixo nível de desenvolvimento do filho. Conclusão Conclui-se que mecanismos de adaptação são necessários para se obter os mesmos níveis de parentalidade de uma condição típica.

The impact of the human development index on stomach cancer incidence in Brazil.

Background: The incidence of stomach cancer (SC) is declining in most countries in the world, potentially associated with increases in the human development index (HDI). This study was conducted to characterise the incidence and trends of SC in the Brazilian population and its correlations with HDI components: longevity, education and income. Methods: Data on incidence of SC from Population-based cancer registries (PBCR) in Brazil during the period 1988-2017 were extracted from the Instituto Nacional de Câncer. Incidence rates were estimated for each PBCR in the same calendar period. Trends were analysed using the Joinpoint Regression Program, and correlations with HDI components (longevity, education and income) were examined using the Pearson test. Results: SC incidence rates in Brazil ranged from 22 to 89/100,000 among men and from 8 to 44/100,000 among women. The highest incidence rates for men and women occurred in northern Brazil. The SC incidence is stable in most of the capitals of the northern and northeast parts of the country, with reductions for both sexes in the South, Southeastern and Midwest. There was an inverse correlation of SC incidence rates for women with the components of HDI education (p = 0.038) and longevity (p = 0.012). For men, the inverse correlation occurred for the longevity HDI (p = 0.013). Conclusion: The improvement of HDIs in Brazil during the study period may have contributed to the stability of SC incidence but was not sufficient to reduce the overall SC incidence in the whole country. To better understand SC incidence in Brazil, efforts should be made towards ensuring that incidence data is recorded by PBCRs promptly.

PANCREATIC CANCER MORTALITY TRENDS AND CORRELATION WITH HUMAN DEVELOPMENT INDEX (HDI) IN BRAZIL OVER 40 YEARS.

BACKGROUND: Pancreatic cancer mortality is greater in countries with a high Human Development Index (HDI). This study analyzed pancreatic cancer mortality rates trends, and their correlation with HDI in Brazil over 40 years. METHODS: Data on pancreatic cancer mortality in Brazil between 1979 and 2019 were obtained from the Mortality Information System (SIM). Age-standardized mortality rates (ASMR) and Annual Average Percent Change (AAPC) were calculated. Pearson's correlation test was applied to compare mortality rates and HDI for three periods: 1986-1995 was correlated with HDI of 1991, 1996-2005 with HDI of 2000, and 2006-2015 with HDI of 2010; and to the correlation of AAPC versus the percentage change in HDI from 1991 to 2010. RESULTS: A total of 209,425 deaths from pancreatic cancer were reported in Brazil, with an annual increase of 1.5% in men and 1.9% in women. There was an upward trend for mortality in most Brazilian states, with the highest trends observed in the North and Northeast states. A positive correlation between pancreatic mortality and HDI was observed over the three decades (r>0.80, P<0.05) and also between AAPC and HDI improvement by sex (r=0.75 for men and r=0.78 for women, P<0.05). CONCLUSION: There was an upward trend in pancreatic cancer mortality in Brazil for both sexes, but rates among women were higher. Mortality trends were higher in states with a higher percentage improvement in HDI, such as the North and Northeast states.

Cancer stage and time from cancer diagnosis to first treatment during the COVID-19 pandemic.

The 2019 coronavirus disease (COVID-19) pandemic has impacted cancer care and the diagnosis of new cases of cancer. We analyzed the impact of the COVID-19 pandemic on patients with cancer by comparing the number of newly diagnosed cases, cancer stage, and time to treatment in 2020 with those in 2018, 2019, and 2021. A retrospective cohort of all cancer cases treated at A.C. Camargo Cancer Center in 2018-2021, identified from the Hospital Cancer Registry, was studied. We analyzed single and multiple primary cancer case and patient characteristics-by year and by clinical stage (early v advanced). Times from diagnosis to treatment were compared according to the most frequent tumor sites between 2020 and the other study years. Between 2018 and 2021, a total of 29,796 new cases were treated at the center including 24,891 with a single tumor and 4,905 with multiple tumors, including nonmelanoma skin cancer. The number of new cases decreased by 25% between 2018 and 2020 and 22% between 2019 and 2020, followed by an increase of about 22% in 2021. Clinical stages differed across years, with the number of new advanced cases decreasing from 17.8% in 2018 to 15.2% in 2020. Diagnoses of advanced-stage for lung and kidney cancer decreased between 2018 and 2020, while the number of thyroid and prostate cancer cases diagnosed in advanced-stages increased from 2019 to 2020. The time from diagnosis to treatment decreased between 2018 and 2020 for breast (55.5 v 48 days), prostate (87 v 64 days), cervical/uterine (78 v 55 days) and oropharyngeal (50 v 28 days) cancers. The COVID-19 pandemic affected the numbers of single and multiple cancers diagnosed in 2020. An increase in the number of advanced-stage cases diagnosed was observed only for thyroid and prostate cancer. This pattern may change in coming years due to the possibility that a significant number of cases went undiagnosed in 2020.

Hodgkin lymphoma in Brazil: trends in incidence and mortality over 4 decades.

BACKGROUND: In Brazil, there is lack of studies on the incidence and mortality of this malignancy. The aim of this study was to describe the profile of HL in Brazil for incidence, mortality and trends. METHODS: Data on incidence in Brazil were collected from Population-Based Cancer Registries (1988-2017) and mortality for 1979-2019. Age-standardized incidence and mortality rates were calculated. Average annual percent change was estimated and analyzed in two calendar periods for mortality (1979-1999 and 2000-2019). RESULTS: Trends in the incidence of HL for males in Brazil declined in two state capitals - Belo Horizonte, -3.7% (95% CI, -7.1 to -0.3); and Salvador, -8.5% (95% CI, -13.0 to -3.8) - and remained stable in other cities. For females, two capitals showed a decrease in incidence: Salvador, -9.5% (95% CI, -15.3 to -3.2) and Porto Alegre, -3.9% (95% CI, -7.0 to -0.8). Mortality rates in males were higher than those in females. However, the decrease in mortality was greater in males, -2.2% (95% CI, -2.5 to -1.8). Age incidence distribution across Brazilian capitals showed a higher incidence among younger (15-30 years) individuals yet no clear incidence among older adults (>60 years). CONCLUSION: The incidence trend of HL in Brazil has remained stable. While the mortality rates have decreased for both sexes. Age distribution for mortality at a young age and older ages follows the bimodal pattern for Brazil as a whole. Finally, further studies are necessary to understand age incidence distribution of HL in Brazil.

RESUMO Contexto A mortalidade por câncer de pâncreas é maior em países com alto Índice de Desenvolvimento Humano (IDH). Este estudo analisou as taxas e tendências de mortalidade por câncer de pâncreas e correlacionou-as com o IDH no Brasil no período de 40 anos. Métodos: Os dados sobre mortalidade por câncer de pâncreas no Brasil, entre 1979 e 2019, foram extraídos do Sistema de Informações sobre Mortalidade (SIM). As taxas de mortalidade padronizadas por idade e variação percentual média anual (AAPC) foram calculadas. O teste de correlação de Pearson foi aplicado para comparar as taxas de mortalidade e IDH em três períodos: 1986-1995 foi correlacionado com o IDH de 1991, 1996-2005 com IDH 2000 e 2006-2015 com IDH 2010; e a correlação da AAPC versus o percentual de variação do IDH de 1991 a 2010. Resultados: Foram notificados 209.425 óbitos por câncer de pâncreas no Brasil no período de 1979 a 2019, com aumento de 1,5% ao ano em homens e de 1,9% em mulheres. Houve tendência de aumento da mortalidade na maioria dos estados brasileiros, com maiores tendências nos estados das regiões Norte e Nordeste. Foi observada uma correlação positiva na mortalidade por câncer de pâncreas e o IDH ao longo de três décadas (r>0,80, P<0,05); também, entre o AAPC e o incremento do IHD entre 1991 e 2010 (r=0,75 para homens e r=0,78 para mulheres, P<0,05). Conclusão: Houve tendência crescente da mortalidade por câncer de pâncreas no Brasil, em ambos os sexos, porém maior entre as mulheres. As tendências de mortalidade foram maiores nos estados com maior percentual de incremento do IDH, como estados das regiões Norte e Nordeste.

Epidemiologia do câncer de pâncreas na América Latina e no Brasil / Epidemiology of pancreatic cancer in Latin America and Brazil

Introdução: O câncer de pâncreas é um tumor de alta letalidade, é o décimo segundo tipo mais comum e a sétima causa de morte, em ambos os sexos, no mundo. Estima-se que o câncer de pâncreas terá um aumento contínuo de incidência e mortalidade nos próximos 20 anos e isso causará um enorme ônus econômico para as populações em todo o mundo. Para o monitoramento e vigilância epidemiológica em câncer, pode-se apoiar em dados secundários como no Sistema de Informação em Mortalidade e dos registros de câncer (de base populacional e hospitalares) e estimativas a partir destes dados; por essa razão, investigou-se a epidemiologia do câncer de pâncreas na América Latina e no Brasil. Métodos: A tese compreende três manuscritos: (i) tendências de incidência, mortalidade e anos de vida ajustados por incapacidade (DALYs), bem como a fração de mortes por câncer de pâncreas atribuíveis a fatores de risco comportamentais e metabólicos em países da América Latina e Caribe (LAC) entre 1990 e 2019 (Global Burden Disease, 2019); (ii) mortalidade por câncer de pâncreas no Brasil e unidades da federação entre 1979 e 2019, dados do Sistema de Informação em Mortalidade (SIM); (iii) comparabilidade, validade, completude e pontualidade para cinco tumores gastrointestinais, câncer de esôfago, estômago, colorretal, fígado e pâncreas, em Registros de Câncer de Base Populacional (RCBPs) brasileiros. Resultados: Observou-se um aumento na incidência, mortalidade e DALYs para o câncer de pâncreas em ambos os sexos na maioria dos países da América Latina e Caribe; as maiores taxas de incidência e mortalidade foram observadas no Uruguai e as menores no Haiti. Redução na fração de mortes atribuíveis ao tabagismo entre 1990 e 2019, para ambos os sexos nos países da LAC; entretanto, aumento dentre os fatores metabólicos. No Brasil, entre 1979 e 2019, foram notificados um total de 209.425 óbitos por câncer de pâncreas, com tendência de aumento de 1,5% ao ano em homens e 1,9% em mulheres. Houve tendência de aumento da mortalidade na maioria dos estados brasileiros, com maiores tendências nas regiões Norte e Nordeste, e correlação positiva entre o índice de desenvolvimento humano e a tendência de aumento da mortalidade por câncer de pâncreas. Dentre os dezesseis RCBPs brasileiros estudados, todos atenderam aos critérios de comparabilidade, porém metade apresentou índices abaixo do esperado para validade e completude para tumores de fígado e pâncreas. Para pontualidade, os dezesseis registros apresentaram mais de 48 meses de atraso na divulgação dos dados em relação ao ano calendário de 2023. Considerações finais: O câncer de pâncreas representa um desafio para a saúde pública nos países da América Latina e no Brasil, diante do desafio na redução da incidência e da mortalidade, assim como na vigilância epidemiológica em câncer através dos RCBPs brasileiros que necessitam de suporte para continuidade do monitoramento da incidência do câncer.

Introduction: Pancreatic cancer is a tumor of high lethality, is the twelfth most common type and the seventh cause of death, in both sexes, in the world. It is estimated that pancreatic cancer will have a continuous increase in incidence and mortality over the next 20 years and this will cause a huge economic burden for populations around the world. For epidemiological monitoring and surveillance in cancer, it is possible to use on secondary data such as the Mortality Information System and cancer registries (population-based and hospital) and estimates from these data, for this reason the epidemiology of pancreatic cancer in Latin America and Brazil was investigated. Methods: The thesis comprises three manuscripts: (i) trends in incidence, mortality and disability-adjusted life years (DALYs) as well as the fraction of pancreatic cancer deaths attributable to behavioral and metabolic risk factors in Latin American and Caribbean (LAC) countries between 1990 and 2019 (Global Burden Disease, GBD 2019); (ii) mortality from pancreatic cancer in Brazil and federal units between 1979 and 2019, data from the Mortality Information System (SIM); (iii) comparability, validity, completeness and timeless for five gastrointestinal tumors, esophageal, stomach, colorectal, liver and pancreatic cancers, in the Brazilian Population-Based Cancer Registries (PBCRs). Results: An increase in the incidence, mortality and DALYs of pancreatic cancer was observed in most countries in Latin America and the Caribbean, the highest incidence and mortality rates were observed in Uruguay and the lowest in Haiti. The fraction of pancreatic cancer deaths attributable to smoking reduced between 1990 and 2019 for both sexes in LAC countries, however, it increased for metabolic risk factors. In Brazil, between 1979 and 2019, a total of 209,425 deaths from pancreatic cancer were reported, with a trend of increase of 1.5% per year in men and 1.9% in women. There was an increase in mortality in most Brazilian states, higher in the North and Northeast regions with a positive correlation between the improvement of the human development index and the trend of increased mortality from pancreatic cancer. Among the sixteen Brazilian PBCRs studied, all agreement the criteria of comparability, but half have lower than expected indices for validity and completeness for liver and pancreatic tumors, and as for timeless the sixteen records are more than 48 months late in the release of data in relation to the calendar year 2023. Conclusions: Pancreatic cancer represents a challenge for public health in LAC and Brazil, given the challenge in reducing incidence and mortality, as well as in epidemiological surveillance in cancer through Brazilian PBCRs to ensure the activity and stability for continued monitoring of cancer incidence.

Versão Brasileira do Questionário de Satisfação com a Prótese (SAT-PRO/Br): validade estrutural, validade concorrente, consistência interna e estabilidade / Brazilian version of the Prosthesis Satisfaction Questionnaire (SAT-PRO/Br): structural validity, concurrent validity, internal consistency and stability

Objetivo: Analisar as propriedades psicométricas do SAT-PRO/Br através da observação da validade estrutural e concorrente, consistência interna e estabilidade. Método: A amostra deste estudo transversal foi consecutiva, não probabilística, constituída por 128 idosos com amputação de membro inferior, com amputação unilateral e que utilizavam a prótese a pelo menos um ano. As propriedades psicométricas foram avaliadas através da validade estrutural (Comparative Fit Index- CFI, Tucker-Lewis Index-TLI, Root Means Square Error of Approximation-RMSEA e Standardized Root Mean Residual-SRMR), validade concorrente utilizando a versão brasileira da Trinity Amputation and Prosthesis Experience Scales - Revised (TAPES-R), além da consistência interna dos itens pelo alfa de Cronbach e estabilidade pelo Intraclass Correlacion Coefficient (ICC). Resultados: O SAT-PRO/Br e a TAPES-R apresentaram forte correlação em relação a validade concorrente. A estabilidade variou de 0,85 a 0,91 através do ICC. Os índices de modelo do ajuste apresentaram valores de CFI de 0,991, TLI de 0,989, RMSEA de 0,045 e o SRMR de 0,074. Observou-se uma boa consistência interna com alfa de Cronbach total de 0.91. Conclusão: As propriedades psicométricas deste estudo sobre o SAT-PRO/Br levam a concluir que esta versão é válida, confiável e apresenta boa consistência interna e estabilidade para ser aplicada em idosos brasileiros amputados de membro inferior.

Objective: To analyze the psychometric properties of the SAT-PRO/Br through the observation of structural and concurrent validity, internal consistency and stability. Method: The sample of this cross-sectional study was consecutive, non-probabilistic, consisting of 128 elderly with lower limb amputation, with unilateral amputation and who used the prosthesis for at least one year. The psychometric properties were evaluated through structural validity (Comparative Fit Index- CFI, Tucker-Lewis Index-TLI, Root Means Square Error of Approximation-RMSEA and Standardized Root Mean Residual-SRMR), concurrent validity using the Brazilian version of Trinity Amputation and Prosthesis Experience Scales - Revised (TAPES-R), in addition to the internal consistency of the items by Cronbach's alpha and stability by the Intraclass Correlacion Coefficient (ICC). Results: The SAT-PRO/Br and TAPES-R showed a strong correlation in relation to concurrent validity. Stability ranged from 0.85 to 0.91 across the ICC. The fit model indices showed CFI values of 0.991, TLI of 0.989, RMSEA of 0.045 and SRMR of 0.074. A good internal consistency was observed with a total Cronbach's alpha of 0.91. Conclusion: The psychometric properties of this study on the SAT-PRO/Br lead to the conclusion that this version is valid, reliable and has good internal consistency and stability to be applied to elderly Brazilians with lower limb amputees.

Métodos de estimativa do gasto energético em amputados de membro inferior: uma revisão sistemática / Methods of estimating energy expenditure in lower limb amputees: a systematic review

Objetivo: Identificar os métodos utilizados para determinar o gasto energético de pessoas com amputação de membro inferior. Método: Revisão sistemática, foram selecionadas as bases de dados MedLine (Medical Literature Analysis and Retrieval System on-line) via Pubmed, Web of Science, Scopus (Elsevier), PsycINFO - APA Psycnet (American Psychological Association) e SPORTDiscus. Foram incluídos estudos originais, observacionais, experimentais, que abordaram a temática do gasto energético em amputados de membro inferior, disponíveis na íntegra, nos idiomas inglês, português e espanhol. Resultados: Os estudos utilizaram principalmente a avaliação do consumo de oxigênio (VO2) por meio do teste de Ergoespirometria e o Índice de Custo Fisiológico através da Frequência Cardíaca. No entanto, algumas pesquisas utilizaram a Escala Subjetiva de Percepção de Esforço, a Escala de aptidão autorreferida e um questionário relacionado a percepção da capacidade de andar. Conclusão: O VO2 é a variável mais fidedigna para avaliação do consumo energético, contudo, testes com medidas diretas podem ser mais difíceis de aplicar, pelas alterações recorrentes à amputação, podendo comprometer o resultado, assim, o uso de variáveis que estimem o consumo energético por meio de medidas indiretas se torna uma alternativa válida, mas é necessário atentar- se no uso da Frequência Cardíaca em populações que utilizem algum tipo de medicamento que possa alterar ou comprometer o resultado.

Objective: The objective of the present study was to identify the methods used to determine energy consumption of people with lower limb amputation. Methods: Systematic review, MedLine (Medical Literature Analysis and Retrieval System online) databases were selected via Pubmed, Web of Science, Scopus (Elsevier), PsycINFO - APA Psycnet (American Psychological Association) and SPORTDiscus . Eligibility criteria: Original, observational, experimental studies, which addressed the topic of energy consumption in lower limb amputees, available in full, in English, Portuguese and Spanish. Results: The studies used mainly the assessment of oxygen consumption (VO2) using the Ergospirometry test and the Physiological Cost Index through Heart Rate. However, some researches used the Subjective Scale of Perception of Effort, the Scale of self-reported fitness and a questionnaire related to the perception of the ability to walk. Conclusion: VO2 is the most reliable variable for assessing energy consumption, however, tests with direct measures can be more difficult to apply, due to recurrent changes to amputation, which may compromise the result, thus the use of variables that estimate energy consumption. through indirect measures it becomes a valid alternative, but it is necessary to pay attention to the use of heart rate in populations that use some type of medication that may alter or compromise the result.

Influence of Sociodemographic Characteristics and Inflammation-Related Gene Variants on the Comfort Level of Caregivers of Patients With Head and Neck Cancer.

Background: Sociodemographic characteristics and inflammatory cytokines, such as interleukin (IL)-1ß, IL-1 cytokine receptor type 2 (IL1R2), IL-6, and triggering receptor expressed on myeloid cells like 2 (TREML2), may influence psychological disorders, including discomfort. Single-nucleotide variants (SNVs) determine individual differences for the modulation of cytokines and indicate that genetics may also influence the comfort levels. However, the relationship between sociodemographic characteristics, holistic comfort, and the roles played by IL1B rs16944, IL1R2 rs4141134, IL6 rs1800795, and TREML2 rs3747742 SNVs on the comfort levels of family caregivers (FCGs) of head and neck cancer (HNC) patients in palliative care (PC) is unknown. Thus, its investigation consisted in the aim of the present study. Methods: A questionnaire was applied to obtain sociodemographic information on 95 FCGs. The genotypes were identified using TaqMan assays. The Holistic Comfort Questionnaire for the Caregiver, which consists of 49 questions, was used to measure comfort levels. Differences between groups were assessed by the t test and linear regression. Results: Employed FCGs (p = .04), those youngest (p = .04), smokers (p = .04), and those with IL1R2 GA or AA genotypes (p = .03) presented lower comfort regarding the overall, environmental, sociocultural, and psychospiritual domains, respectively. Conclusions: Employment status, smoking habit, young age, and SNV IL1R2 rs4141134 could influence the comfort levels of FCGs of patients with HNC in PC.

Agreement and validity of asbestos-related cancers in the hospital information system of the Brazilian Unified Health System. / Concordância e validade dos diagnósticos de cânceres associados ao asbesto no sistema de informação hospitalar do Sistema Único de Saúde.

OBJECTIVE: To estimate the degree of agreement and validity of diagnoses of asbestos-related malignant neoplasms registered in the Hospital Information System of the Brazilian Unified Health System (SIH/SUS), in comparison to the Hospital Cancer Registries of the State of São Paulo (HCR/SP). METHODS: Deaths with records of malignant neoplasms associated with asbestos were identified and extracted from SIH/SUS between 2007 and 2014. Deaths in cases registered in the HCR/SP were extracted for the same period. The databases were linked using software Link Plus. A single ICD-10-coded diagnosis selected from each system was analyzed. The proportion of agreement, and the sensitivity, specificity and predictive values were estimated. RESULTS: 19,458 pairs were found with records in both bases. The proportion of agreement was high, ranging from 92.4% for the unknown primary site, to 99.7% for cancer of the pleura. The Kappa Index ranged from 0.05 (95%CI 0.04 - 0.07) for cancer of the pleura to 0.85 (95%CI 0.84 - 0.87) for lung cancer. Sensitivity varied from 0.08 (95%CI 0.01 - 0.25) for cancer of the pleura, to 0.90 (95%CI 0.90 - 0.91) for lung cancer. CONCLUSION: Diagnosis of asbestos-related malignancies reached higher levels of agreement and validity when common. Rare diagnoses showed low accuracy in SIH/SUS.

OBJETIVO: Estimar o grau de concordância e validade dos diagnósticos de neoplasias malignas relacionadas à exposição ao asbesto registrados no Sistema de Informação Hospitalar do Sistema Único de Saúde (SIH/SUS), em comparação aos Registros Hospitalares de Câncer do Estado de São Paulo (RHC/SP). MÉTODOS: Óbitos com registros de neoplasias malignas associadas ao asbesto foram identificados e extraídos do SIH/SUS entre 2007 e 2014. Óbitos nos casos de câncer registrados na base do RHC/SP foram extraídos para o mesmo período. Essas bases foram unidas pelos mesmos indivíduos empregando-se o software Link Plus. Um único diagnóstico codificado pela CID-O3 ou CID-10 selecionado de cada sistema foi analisado. A proporção de concordância e a sensibilidade, especificidade e valores preditivos foram estimados. RESULTADOS: Encontraram-se 19.458 pares com registros nas duas bases. A proporção de concordância foi elevada, variando de 92,4% para a localização primária desconhecida a 99,7% para o câncer de pleura. O índice Kappa variou de 0,05 (IC95% 0,04 - 0,07) para o câncer de pleura a 0,85 (IC95% 0,84 - 0,87) para o câncer de pulmão. A menor sensibilidade foi de 0,08 (IC95% 0,01 - 0,25), para o câncer de pleura, e a maior de 0,90 (IC95% 0,90 - 0,91), para o câncer de pulmão. CONCLUSÃO: Diagnósticos de neoplasias malignas associadas ao asbesto alcançaram maiores níveis de concordância e validade quando comuns. Os diagnósticos mais raros apresentaram baixa acurácia no SIH/SUS.

Validade e confiabilidade da versão brasileira da Trinity Amputation and Prosthesis Experience Scales - Revised (TAPES-R) / Validity and reliability of the brazilian version of Trinity Amputation and Prosthesis Experience Scales ­ Revised (TAPES-R)

Objetivo: Avaliar a validade e confiabilidade da versão brasileira da TAPES-R em uma população com amputação de membro inferior. Método: Participaram deste estudo transversal 102 pessoas com amputação de membro inferior, usuárias de prótese. Foram avaliadas as propriedades psicométricas (validade concorrente, grau de concordância (Índice de Kappa) e confiabilidade (ICC) intra e interobservador, além da consistência interna dos itens pelo alfa de Cronbach) da versão brasileira da TAPES-R. Para avaliação da validade concorrente foi utilizado o Prosthesis Evaluation Questionnaire (PEQ). Resultados: A TAPES-R se correlacionou com o PEQ, com exceção das subescalas de ajuste social e geral. O ICC interobservador variou de 0,38 a 0,88 na parte 1 e de 0,27 a 0,88 na parte 2, já o ICC intraobservador variou de 0,63 a 0,83 na parte 1 e de 0,27 a 0,79 na parte 2. O índice de Kappa variou de 0,18 a 0,66 na análise interobservador e de 0,25 a 0,69 na análise intraobservador. O Alfa de Cronbach variou de 0,75 a 0,89. Conclusão: A avaliação das propriedades psicométricas permite concluir que a TAPES-R é válida, confiável e apresenta uma boa consistência interna para ser aplicada em adultos brasileiros amputados de membro inferior.

Objective: Evaluate the validity and reliability of the Brazilian version of TAPES-R in people with lower limb amputation. Method: 102 people with lower limb amputation who used a prosthesis participated in this cross-sectional study. The psychometric properties (concurrent validity, degree of agreement (Kappa Index) and intra and interobserver reliability (ICC), in addition to the internal consistency of the items by Cronbach's alpha) of the Brazilian version of TAPES-R were evaluated. To assess concurrent validity, the Prosthesis Evaluation Questionnaire (PEQ) was used. Results: TAPES-R was correlated with PEQ, except for the subscales of social and general adjustment. The inter-observer ICC ranged from 0.38 to 0.88 in part 1 and from 0.27 to 0.88 in part 2, whereas the intra-observer ICC ranged from 0.63 to 0.83 in part 1 and 0.27 to 0.79 in part 2. The Kappa index varied from 0.18 to 0.66 in the inter-observer analysis and from 0.25 to 0.69 in the intra-observer analysis. Cronbach's alpha ranged from 0.75 to 0.89. Conclusion: The evaluation of psychometric properties allows us to verify that a TAPES-R is valid, reliable and has a good internal consistency to be applied to Brazilian adults with lower limb amputations.

Recovering records on cancer of the larynx from anonymous health information databases.

OBJECTIVE: To develop a linkage algorithm to match anonymous death records of cancer of the larynx (ICD-10 C32X), retrieved from the Mortality Information System (SIM) and the Hospital Information System of the Brazilian Unified National Health System (SIH-SUS) in Brazil. METHODOLOGY: Death records containing ICD-10 C32X codes were retrieved from SIM and SIH-SUS, limited to individuals aged 30 years and over, between 2002 and 2012, in the state of São Paulo. The databases were linked using a unique key identifier developed with sociodemographic data shared by both systems. Linkage performance was ascertained by applying the same procedure to similar non-anonymous databases. True pairs were those having the same identification variables. RESULTS: A total of 14,311 eligible death records were found. Most records, 10,674 (74.6%), were exclusive to SIM. Only 1,853 (12.9%) deaths were registered in both systems, representing true pairs. A total of 1,784 (12.5%) cases of laryngeal cancer in the SIH-SUS database were tracked in SIM with different causes of death. The linkage failed to match 167 (9.4%) records due to inconsistencies in the key identifier. CONCLUSION: The authors found that linking anonymous data from mortality and hospital records is a feasible measure to track missing records and may improve cancer statistics.

Differences in mortality of cancer patients with COVID-19 in a Brazilian cancer center.

INTRODUCTION: To analyze COVID-19 mortality in cancer patients and associated factors such as age, sex, type of insurance, situation at COVID-19 diagnosis, and cancer histology during the pandemic at a cancer center in Brazil. METHODS: Cross-sectional study carried out from April 02, 2020 to August 31, 2020 at A.C. Camargo Cancer Center (ACCCC), in São Paulo, Brazil. Cases were extracted from the Hospital Cancer Registry. COVID-19 lethality rates by histology were calculated; multiple logistic regression was used to identify factors associated with COVID-19 mortality. The log-rank test was applied to compare the survival curves for each variable. RESULTS: Of the 411 patients analyzed, 51 (12.4%) died due to COVID-19. Death occurred at an average age of 63 years. The fatality rate was higher for lung (0.333) and hematological (0.213) cancers and was associated with age over 60 years. The greatest chances of death from COVID-19 were in cases of lung (odds ratio, OR, 4.05, 95% confidence interval, CI 1.33-12.34) and hematological (OR 2.17, 95% CI 0.96-4.90) cancers, and in patients currently undergoing cancer treatment (OR 2.77, 95% CI 1.25-6.13). There were no statistical differences in survival by sex, age group, type of insurance, situation at the diagnosis of COVID-19, and histology of cancer for COVID-19. CONCLUSIONS: Mortality due to COVID-19 in cancer patients is heterogeneous. These findings reinforce the need for individualized strategies for the management of different types of cancer that reduce the risk of death from COVID-19.

RESUMO: Objetivo: Desenvolver um algoritmo de vinculação de registros para parear registros de óbito por câncer de laringe (CID-10 C32X), recuperados do Sistema de Informação de Mortalidade (SIM) e do Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH-SUS) do Brasil. Métodos: Foram filtrados registros de óbitos contendo códigos CID-10 C32X do SIM e do SIH-SUS, de indivíduos de mais de 30 anos, entre 2002 e 2012, no Estado de São Paulo. As bases de dados foram vinculadas por meio de um identificador único e de variáveis sociodemográficas comuns a ambos os sistemas. O desempenho da vinculação de dados foi aferido aplicando-se o mesmo procedimento em bancos de dados nominais. Os pares verdadeiros apresentavam os mesmos valores nas variáveis de identificação. Resultados: Ao todo, 14.311 registros elegíveis de óbito foram encontrados. A maioria dos registros, 10.674 (74.6%), era exclusiva do SIM. Apenas 1.853 (12.9%) óbitos foram registrados em ambos os sistemas, representando pares verdadeiros. Um total de 1.784 (12.5%) casos de câncer de laringe presentes no SIH-SUS constavam com diferentes causas de óbito no SIM. Houve falha na vinculação em 167 (9.4%) registros, devido a inconsistências na chave de identificação. Conclusão: Constatou-se que a vinculação de dados anônimos de registros hospitalares e registros de óbito é viável e pode auxiliar na melhoria de estatísticas de câncer.
