RESUMEN
BACKGROUND: Breast cancer is the most common type of cancer worldwide. If diagnosed and treated early, it has a high chance of cure, and for this, screening tests are necessary, namely mammograms, which are the most commonly used. The objective of this study was to analyze the association between the number of screening and diagnostic mammograms and the number of hospitalizations and deaths from breast cancer. METHODS: This is a cross-sectional, analytical, retrospective study with secondary data made available by the Ministry of Health. Pearson correlation analysis was employed to assess whether the number of mammograms is associated with the number of deaths and hospitalizations, Poisson regression was used to assess whether an increase in the number of mammograms and hospitalizations is related to the number of deaths, and the Cox-Stuart test was used to analyze the temporal trend of the variables under study and the projection of time series. RESULTS: There was a strong positive correlation for all age groups when relating the variables hospitalizations and deaths, a moderate-to-strong correlation for the variables mammography and hospitalization, and a weak correlation for the variables mammography and death. There was no statistical significance in the relationship between the number of mammograms and deaths, whereas the hospitalization variable had a significant impact in relation to death, increasing the chance by 0.015%. There has also been a significant growth trend in the variables deaths and hospitalizations in Brazil over the years. CONCLUSIONS: A growing trend was identified from 2013 to 2021, both in hospitalizations and deaths, thus suggesting that strategies aimed at reformulating public health policies are necessary for earlier diagnosis in order to improve the treatment of breast cancer and the prognosis of the disease.

OBJECTIVE: To identify the difference in breast cancer mortality rates among young women according to countries' economic classification. METHODS: A systematic literature review included retrospective studies on breast cancer mortality rates in women aged 20 to 49 years. Databases used were PubMed, Web of Science, Scopus, and Virtual Health Library, with articles selected in English, Portuguese, and Spanish. The study selection and analysis were conducted by two pairs of researchers. Data from 54 countries were extracted, including 39 high-income, 12 upper-middle-income, and 3 lower-middle-income countries. A meta-analysis was performed with the quantitative data from two studies. RESULTS: Six articles met the inclusion criteria. Four were analyzed descriptively due to data diversity, and two were included in the meta-analysis. The pooled mortality rate for high-income countries was 10.2 per 100,000 women (95% CI: 9.8-10.6), while for upper-middle-income countries, it was 15.5 per 100,000 women (95% CI: 14.9-16.1). Lower-middle-income countries had a pooled mortality rate of 20.3 per 100,000 women (95% CI: 19.5-21.1). The decrease in mortality rates in high-income countries was statistically significant (p<0.05). CONCLUSION: Mortality rates for breast cancer among young women have decreased significantly in high-income countries but have increased in lower-income countries. This disparity underscores the impact of insufficient investment in preventive measures, health promotion, early diagnosis, and treatment on young women's mortality in lower-income countries.

Background: Patients in serious condition due to COVID-19 often require special care in intensive care units (ICUs). This disease has affected over 758 million people and resulted in 6.8 million deaths worldwide. Additionally, the progression of the disease may vary from individual to individual, that is, it is essential to identify the clinical parameters that indicate a good prognosis for the patient. Machine learning (ML) algorithms have been used for analyzing complex medical data and identifying prognostic indicators. However, there is still an urgent need for a model to elucidate the predictors related to patient outcomes. Therefore, this research aimed to verify, through ML, the variables involved in the discharge of patients admitted to the ICU due to COVID-19. Methods: In this study, 126 variables were collected with information on demography, hospital length stay and outcome, chronic diseases and tumors, comorbidities and risk factors, complications and adverse events, health care, and vital indicators of patients admitted to an ICU in southern Brazil. These variables were filtered and then selected by a ML algorithm known as decision trees to identify the optimal set of variables for predicting patient discharge using logistic regression. Finally, a confusion matrix was performed to evaluate the model's performance for the selected variables. Results: Of the 532 patients evaluated, 180 were discharged: female (16.92%), with a central venous catheter (23.68%), with a bladder catheter (26.13%), and with an average of 8.46- and 23.65-days using bladder catheter and submitted to mechanical ventilation, respectively. In addition, the chances of discharge increase by 14% for each additional day in the hospital, by 136% for female patients, 716% when there is no bladder catheter, and 737% when no central venous catheter is used. However, the chances of discharge decrease by 3% for each additional year of age and by 9% for each other day of mechanical ventilation. The performance of the training data presented a balanced accuracy of 0.81, sensitivity of 0.74, specificity of 0.88, and the kappa value was 0.64. The test performance had a balanced accuracy of 0.85, sensitivity 0.75, specificity 0.95, and kappa value of 0.73. The McNemar test found that there were no significant differences in the error rates in the training and test data, suggesting good classification. This work showed that female, the absence of a central venous catheter and bladder catheter, shorter mechanical ventilation, and bladder catheter duration were associated with a greater chance of hospital discharge. These results may help develop measures that lead to a good prognosis for the patient.

Anaplastic large cell lymphoma associated with breast implants is a relatively new disease that deserves attention from the academic community. Brazil figures as one of the protagonists in plastic surgery, however publications are insufficient and very few cases are reported in comparison to other countries. It is a disease with excellent prognosis when diagnosed early and treated effectively, but for this to happen, it is essential that health care professionals and the patient understand its pathology. We reported two cases in a small town during a short period of time. In both cases reported by this study, the patients presented late seroma, associated with pain as a clinical presentation, at 13 and 9 years after the placement of silicone implants with textured polyurethane surfaces. After the procedure, the patients were screened for cancer. Further research with more robust samples is still needed to fully determine the risks and benefits of using textured versus smooth implants.
RESUMEN
Colorectal cancer (CRC) is the leading cause of death due to cancer worldwide. In Brazil, it is the second most frequent cancer in men and women, with a mortality reaching 9.4% of those diagnosed. The aim of this study was to analyze the spatial heterogeneity of CRC deaths among municipalities in south Brazil, from 2015 to 2019, in different age groups (50-59 years, 60-69 years, 70-79 years, and 80 years old or more) and identify the associated variables. Global Spatial Autocorrelation (Moran's I) and Local Spatial Autocorrelation (LISA) analyses were used to evaluate the spatial correlation between municipalities and CRC mortality. Ordinary Least Squares (OLS) and Geographically Weighted Regression (GWR) were applied to evaluate global and local correlations between CRC deaths, sociodemographic, and coverage of health care services. For all age groups, our results found areas with high CRC rates surrounded by areas with similarly high rates mainly in the Rio Grande do Sul state. Even as factors associated with CRC mortality varied according to age group, our results suggested that improved access to specialized health centers, the presence of family health strategy teams, and higher rates of colonoscopies are protective factors against colorectal cancer mortality in southern Brazil.

BACKGROUND: Lung cancer (LC) is one of the main causes of mortality in Brazil; geographic, cultural, socioeconomic and health access factors can affect the development of the disease. We explored the geospatial distribution of LC mortality, and associated factors, between 2015 and 2019, in Parana state, Brazil. METHODS AND FINDINGS: We obtained mortality (from the Brazilian Health Informatics Department) and population rates (from the Brazilian Institute of Geography and Statistics [IBGE]) in people over 40 years old, accessibility of oncology centers by municipality, disease diagnosis rate (from Brazilian Ministry of Health), the tobacco production rate (IBGE) and Parana Municipal Performance Index (IPDM) (from Parana Institute for Economic and Social Development). Global Moran's Index and Local Indicators of Spatial Association were performed to evaluate the spatial distribution of LC mortality in Parana state. Ordinary Least Squares Regression and Geographically Weighted Regression were used to verify spatial association between LC mortality and socioeconomic indicators and health service coverage. A strong spatial autocorrelation of LC mortality was observed, with the detection of a large cluster of high LC mortality in the South of Parana state. Spatial regression analysis showed that all independent variables analyzed were directly related to LC mortality by municipality in Paraná. CONCLUSIONS: There is a disparity in the LC mortality in Parana state, and inequality of socioeconomic and accessibility to health care services could be associated with it. Our findings may help health managers to intensify actions in regions with vulnerability in the detection and treatment of LC.

Heavy truck drivers represent a social group of great importance to any country's economy. Their professional activity requires a high level of dedication. Due to the irregular hours in their work routine and adopted habits, they mostly predispose them to a diversity of health problems. The purpose of this study is to perform a systematic review and meta-analysis aiming to identify the prevalence of diabetes, hypertension, and obesity in Latin American Truck Drivers. We searched the PubMed, Web of Science, Scopus and LILACS databases, for scientific publications articles, as reported by The PRISMA Statement. From 1,382, 7 studies were included according to the established criteria. The hypertension prevalence found was 34.2%, diabetes was of 9.2% and the highest prevalence found was for overweight and obesity (56%). Meta-analysis presented that drivers have a higher prevalence of overweight or obesity when compared to eutrophic individuals and that drivers with diabetes and hyperglycemia have a lower prevalence. Due to their work activity, their access to the health system is compromised limiting any type of monitoring of their health. This study showed that there is, in Latin America, an investment and assistance gap, both in the health sector and in the research section, for this professional category, which is so important to the economy of these countries. These data should help to identify the difficulties faced by this professional in health assistance, road safety, public safety, leisure and social life. This research also highlighted that they are young and already have the first sign of non-transmissible chronic diseases, which is overweight and obesity.

Objective: Compare the breast cancer mortality rate and the rate of mammograms with socioeconomic factors, in Brazilian´s Federative Units, during the period of 2015 to 2021. Methods: This is an ecological study, of a descriptive nature, which covers the 27 Brazilian federative units, using secondary data extracted from the DATASUS System. The information analyzed was mammography data, breast cancer mortality, demographic and economic data of the resident population and women over 20 years of age. Results: There is a direct relationship between mortality rate and mammograms rates in the Federative Units. The data obtained for Brazil presents a total of 133,048 deaths from breast cancer and 17,324,526 mammography exams in the period from 2015 to 2021. In other words, Brazil presents a standardized mortality rate value, 19.25 deaths per 100,000 women. Regarding the mammography rate, the value of the exam-specific mammography rate was 2,506.55 per 100,000 women. In relation to socioeconomic data by mortality rate group, higher mortality rates from breast cancer present higher rates in the variables: income rate by State (2,594.86), people with income (63.5), average percentage of women with more over 50 years old (29.5%), women with average years of education (6.64), white population (55.1%) and mammography exam rate (2873.20). When analysing the highest rates of mammography exam rates, higher rates are observed income rate by State (2,161.47), people with income (62.5%), average percentage of women over 50 years old (28.6%), women with an average number of years of education (5.8). Conclusion: Brazil has a high mortality rate due to breast cancer, when compared to other countries. The reasons are diverse, such as the modern, industrialized and populous lifestyle. The Federative Units with the highest mortality rate also have high rates of mammograms, that is, in the Federative Units with "better" sociodemographic conditions, the South and Southeast.

OBJECTIVE: To analyze the characteristics associated with vaccination against Covid-19 in pregnant and postpartum women with Severe Acute Respiratory Syndrome in Brazil and to investigate a possible association between vaccination and the clinical course and outcome of the disease. METHODS: Retrospective cohort study of hospitalized pregnant and postpartum women diagnosed with Severe Acute Respiratory Syndrome (SARS) by SARS-CoV-2, presenting onset of signs and symptoms between May and October 2021. Secondary data were used, available in the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe). Data were analyzed using the SPSS statistical program, medians were applied to present continuous variables and frequencies, and proportions were calculated for categorical variables, using logistic and multivariate regression analysis. RESULTS: The final study population included 3,585 pregnant and postpartum women, of whom 596 (16.6) were vaccinated: 443 (74.3%) received one dose and 153 (25.7%) received two doses. They were factors associated with non-vaccination against Covid-19 age ≤ 19 anos (OR: 2.57; IC95% 1.40;4.71), non-white women (OR: 1.34; IC95% 1.07;1.67) and those who required ventilatory support (OR: 1.51; IC95% 1.19;1.90) and invasive ventilation (OR: 2.05; IC95% 1.37;3.08). On the other hand, vaccination was associated with advanced maternal age (OR: 0.60; IC95% 0.48;0.76), presence of comorbidities (OR: 0.57; IC95% 0.45;0.72) and loss of taste (OR: 0.63; IC95% 0.48;0.82). CONCLUSIONS: Demographic, ethnic-racial and clinical characteristics were associated with the vaccination status of pregnant and postpartum women with SARS by SARS-CoV-2 in Brazil. Vaccination against Covid-19 in the obstetric population has already shown positive results in the evolution of severe cases, which reiterates its importance. It is essential that health services advance vaccination against Covid-19 in the obstetric population, especially adolescentes and non-white women.

Abstract Aims: To identify the histopathological alterations in organs of Wistar rats to evaluate toxic effects of use of Annonamuricata Raw Leaf Extract (AMRLE) alone or in association with DMBA. Settings and Design: Sixty female Wistar rats were used, separated into groups and treated with a single dose of 65 mg/kg of DMBA and/or with 50; 100 and 200 mg/kg of AMRLE. Hematoxylin-Eosin (HE) and 1% methylene blue stains were used in the histopathological analysis and quantification of Aberrant Crypts (ACs) and Aberrant Crypt Focus (ACF). Fischer and Kruskal Wallis tests were used in the statistical analysis. Results: The administration of 65 mg/kg of DMBA and/or 50, 100 and 200 mg/kg of AMRLE did not influence weight development. Some histopathological alterations (hepatic steatosis; inflammatory foci in the liver, kidney and lung; pulmonary lymphoid hyperplasia, ectasia and hyperplasia in mammary gland epithelium) and the development of ACs and ACF in the intestinal colon were observed in all groups, except in the group negative control, with no statistical difference between analysed groups. Conclusions: Histopathological alterations and the formation of ACs and ACF did not show a statistically significant difference between the groups analysed. However, although AMRLE has antioxidant effects due to the presence of phenolic components, there was still the formation of some pathological processes that may be related to the isolated toxic action of DMBA and/or associated with other components of AMRLE, since these changes were not seen in the negative control group.
Resumen Objetivos: Identificar las alteraciones histopatológicas en órganos de ratas Wistar para evaluar los efectos tóxicos del uso del Extracto de Hoja Cruda de Annona muricata (AMRLE) solo o en asociación con DMBA. Configuración y diseño: Se utilizaron sesenta ratas hembras Wistar, se separaron en grupos y se trataron con una dosis única de 65 mg/kg de DMBA y/o con 50, 100 y 200 mg/kg de AMRLE. Se utilizaron tinciones de hematoxilina-eosina (HE) y azul de metileno al 1% en el análisis histopatológico y la cuantificación de criptas aberrantes (CA) y focus de criptas aberrantes (FCA). En el análisis estadístico se utilizaron las pruebas de Fischer y Kruskal Wallis. Resultados: La administración de 65 mg/kg de DMBA y/o 50, 100 y 200 mg/kg de AMRLE no influyó en el desarrollo del peso. Se observaron algunas alteraciones histopatológicas (esteatosis hepática; focus inflamatórios en el hígado, riñón y pulmón; hiperplasia, ectasia en epitelio de la glándula mamaria e hiperplasia linfoide pulmonar) y el desarrollo de CA y FCA en el colon intestinal en todos los grupos, excepto en el grupo control negativo, sin diferencias estadísticas entre los grupos analizados. Conclusiones: Las alteraciones histopatológicas y la formación de CA y FCA no mostraron diferencias estadísticamente significativas entre los grupos analizados. Sin embargo, aunque AMRLE tiene efectos antioxidantes debido a la presencia de componentes fenólicos, aún existe la formación de algunos procesos patológicos que pueden estar relacionados con la acción tóxica aislada del DMBA y/o asociados con otros componentes de AMRLE, ya que estos cambios no fueron observados en el grupo control negativo.

RESUMEN
PURPOSE: The aim is to verify the impact of the Covid-19 pandemic on women's healthcare and medical assistance in Brazil. PATIENTS AND METHODS: This exploratory cross-sectional study evaluated a non-probabilistic sample of women above 20 years old, carried out between August and September of 2020, through a snowball sampling using a Google Forms application. RESULTS: From a total of 2495 women, more than 70% have not been screened for cervical cancer (77.8% of 2244 women aged for screening), and more than 80% have not been screened for breast cancer (80.2% from 1325 women aged for mammography) during the pandemic. Also, 55.2% of the women did not undergo routine blood tests during the same period. The most frequent reasons for not performing screening and routine tests were: they were up to date; fear of contracting Covid-19; they decided to postpone it until after the end of the pandemic; they were unable to schedule the appointment at the healthcare center for whatever reason; and the healthcare center was only attending Covid-19 patients. Women with no comorbidities have performed significantly more mammograms and routine blood tests than women with comorbidities. In addition, women with comorbidities who were used to perform periodic medical follow-up have done it substantially more than women with no comorbidities during the pandemic. CONCLUSION: As observed, there was a significant decrease in women's access to the healthcare system during this pandemic. Many participants reported that they had not attended any screening tests, and some reasons included fear of getting infected and due to the public measures of social distancing. The consequences are late diagnoses and a worse prognosis. It might impact the healthcare systems around the world in the next few years. Further studies should be done to follow these consequences.
RESUMEN
Global suicide rates have increased in recent decades becoming a serious social and public health problem. In Brazil, rates have been increasing annually. We aimed to analyze the correlation between suicide mortality rates and global economic and political crisis periods of 2008 and 2014 in Brazil. The analysis of suicide mortality in Brazil was done using a time-series segmented linear regression model that estimated the trend of rates over time. To obtain the model, changes in the trend of both abrupt and gradual suicide rates were investigated. The results indicate statistically significant changes showing an upward trend of suicide rates during the world economic crisis (2008-2013) and during the economic and political crisis in Brazil (2014-2017) compared to previous periods, especially at the extremes of schooling (3 < years and > 8 years). Among white and parda, there were significant trend rates increases in both periods and in different regions. In the Northeast and South regions, we observed a significant increase in the trend rate for males after the Brazilian economic and political crisis (2014 to 2017). We can conclude that the national suicide rates were influenced by the economic and political instability that our country has been going through since 2008, affecting each region differently. Further studies are needed to explore the reasons for interregional differences and the relation of suicide with unemployment rates and possible economic predictors.
RESUMEN
Background: No other disease has killed more than ischemic heart disease (IHD) for the past few years globally. Despite the advances in cardiology, the response time for starting treatment still leads patients to death because of the lack of healthcare coverage and access to referral centers. Objectives: To analyze the spatial disparities related to IHD mortality in the Parana state, Brazil. Methods: An ecological study using secondary data from Brazilian Health Informatics Department between 2013-2017 was performed to verify the IHD mortality. An spatial analysis was performed using the Global Moran and Local Indicators of Spatial Association (LISA) to verify the spatial dependency of IHD mortality. Lastly, multivariate spatial regression models were also developed using Ordinary Least Squares and Geographically Weighted Regression (GWR) to identify socioeconomic indicators (aging, income, and illiteracy rates), exam coverage (catheterization, angioplasty, and revascularization rates), and access to health (access index to cardiologists and chemical reperfusion centers) significantly correlated with IHD mortality. The chosen model was based on p < 0.05, highest adjusted R2 and lowest Akaike Information Criterion. Results: A total of 22,920 individuals died from IHD between 2013-2017. The spatial analysis confirmed a positive spatial autocorrelation global between IDH mortality rates (Moran's I: 0.633, p < 0.01). The LISA analysis identified six high-high pattern clusters composed by 66 municipalities (16.5%). GWR presented the best model (Adjusted R2: 0.72) showing that accessibility to cardiologists and chemical reperfusion centers, and revascularization and angioplasty rates differentially affect the IHD mortality rates geographically. Aging and illiteracy rate presented positive correlation with IHD mortality rate, while income ratio presented negative correlation (p < 0.05). Conclusion: Regions of vulnerability were unveiled by the spatial analysis where sociodemographic, exam coverage and accessibility to health variables impacted differently the IHD mortality rates in Paraná state, Brazil. Highlights: The increase in ischemic heart disease mortality rates is related to geographical disparities.The IHD mortality is differentially associated to socioeconomic factors, exam coverage, and access to health.Higher accessibility to chemical reperfusion centers did not necessarily improve patient outcomes in some regions of the state.Clusters of high mortality rate are placed in regions with low amount of cardiologists, income and schooling.

INTRODUCTION: Aberrant Crypt (AC) and Aberrant Crypt Focus (ACF) are considered pre-neoplasic lesions, ranging from hyperplasia to different degrees of dysplasia in the colon. This work aimed to evaluate and quantify the chemopreventive activity of Zingiber officinale essential oil in the colorectal region of Wistar rats. MATERIALS AND METHODS: We extracted the essential oil from ginger rhizomes and carried out ACF induction, in rats, with 1.2 Dimethylhydrazine (DMH) at a 20 mg/kg dose. The experimental groups were GI (negative control); GII (positive induction control); GIII (DMH + essential oil); GIV (DMH +5-Florouracil) and GV (essential oil). The histological techniques used were methylene blue, hematoxylin-eosin (HE) dyeing, and immunohistochemistry (IHQ). RESULTS: The major essential oil compounds were citral (17.25%), δ-citral (10.25%), camphene (9.55%), α-zingiberene (7.57%), nerol (6.37%) and plelandrene (6.83%). For the presence of AC or ACF, we did not observe them in GI and GV, while in GII and GIII, they were observed, in high values, in both regions, but only in the distal region, there was a significant difference between them. For GIV, for both regions, there were significant lower numbers of AC when compared to GIII. As observed, with HE, there were hyperplastic and dysplastic ACF in the proximal and distal portions of the colon. For IHQ analyses, there were positively PCNA antibody marked cells in all experimental groups. Yet, there was no significant correlation of mitotic index among them. Moreover, the results of GIII compared to GIV were very similar. CONCLUSION: In this sense, the Zingiber officinale essential oil has good antioxidant potential because it presents a mixture of monoterpene and sesquiterpene compounds. Thus, it is able to develop a chemoprotective effect, as it presented similar results to the standard drug, showing cell proliferation control.

We aimed to characterize microbiologically clinical isolates of R. mucilaginosa isolated from colonization of a patient with chronic renal disease (CKD), as well as to evaluate their phylogeny, antifungal susceptibility, virulence, and pathogenicity in order to infer the potential to become a possible infective agent. For this study, two isolates of R. mucilaginosa from oral colonization of a CKD patient were isolated, identified and characterized by classical (genotypic and phenotypic) methods. Susceptibility to conventional antifungals was evaluated, followed by biofilm production, measured by different techniques (total biomass, metabolic activity, colony forming units and extracellular matrix quantification). Finally, the pathogenicity of yeast was evaluated by infection of Tenebrio molitor larvae. All isolates were resistant to azole and sensitive to polyenes and they were able to adhere and form biofilm on the abiotic surface of polystyrene. In general, similar profiles among isolates were observed over the observed periods (2, 24, 48 and 72 hours). Regarding extracellular matrix components of biofilms at different maturation ages, R. mucilaginosa was able to produce eDNA, eRNA, proteins, and polysaccharides that varied according to time and the strain. The death curve in vivo model showed a large reduction in the survival percentage of the larvae was observed in the first 24 hours, with only 40 % survival at the end of the evaluation. We infer that colonization of chronic renal patients by R. mucilaginosa offers a high risk of serious infection. And also emphasize that the correct identification of yeast is the main means for an efficient treatment.
RESUMEN
O objetivo deste estudo foi avaliar a mortalidade por diferentes tipos de cânceres em crianças de 0 a 4 anos, e a distribuição destes óbitos para as cinco regiões brasileiras. Os números de casos registrados e de óbitos foram provenientes do Instituto Nacional do Câncer (INCA) e Sistema de Informações sobre Mortalidade (SIM/DATASUS). As informações sobre nascidos vivos foram coletadas no SINASC. O período de análise foi de 1996 a 2017. Os tipos de neoplasias com maior número de óbitos notificados foram as leucemias e as neoplasias do Sistema Nervoso Central. O número de óbitos em crianças na faixa etária estudada por neoplasias malignas foram foi de 2.597 mortes, sendo as leucemias, as neoplasias do Sistema Nervoso Central e os neuroblastomas responsáveis por aproximadamente 70% destas mortes. A frequência de mortes em relação ao tipo de câncer indicou que as neoplasias do sistema nervoso central apresentam mortalidade de 36,27%; seguida por neuroblastomas com 32,13%; leucemias, com 29,31%; e neoplasias dos tecidos moles, 21,56%. As regiões Sudeste e Nordeste apresentaram maior número de casos. Os resultados desta pesquisa indicaram elevado número de casos de câncer e óbito de crianças de 0-4 anos, reforçando a necessidade de constantes investimentos para um melhor acesso destes pacientes ao sistema de saúde, considerando que diagnóstico e tratamento são importantes para a redução da mortalidade infantil.
Mortality by different types of cancer in 0 - 4 year-old children and its distribution for the five Brazilian regions are investigated. Method: number of registered cases and deaths were retrieved derived from the National Institute of Cancer (INCA) and from the Mortality Information System (SIM/DATASUS). Information on live births was retrieved from SINASC for the period of analysis between 1996 and 2017. Results: types of cancer with the highest number of deaths notified were leukemia and cancers of the Central Nervous System. Number of death in children within the age bracket, with malignant cancer, reached 2,597, with leukemia, cancers of the Central Nervous System and neuroblastomas causing approximately 70% of deaths. Frequency of deaths with regard to cancer type indicates that cancers of the central nervous system had a 36.27% of deaths, followed by neuroblastomas, with 32.13%, leukemias, with 29.31% and cancers of the soft tissues, with 21.65%. The southeastern and northeastern regions of Brazil had the highest indexes. Conclusions: Results reveal high incidence of cancer cases and deaths in 0 4 year-old children, requiring constant investments for better access of patients to health systems where diagnosis and treatment are essential for the decrease of child mortality.
RESUMEN
OBJECTIVE: Malignant breast cancer is the leading cause of death by cancer in young women. The study aimed to determine if breast cancer mortality among young women has increased between the period from 1996 to 2017 in Brazil. METHODS: A time-series analysis of breast cancer mortality rate in young women (20-39 years old) was carried out. Mortality data, from 1996 to 2017, were collected from the Mortality Information System of the Health Ministry, and demographic data, from the Brazilian Institute of Geography and Statistics. Trends in mortality were performed by Joinpoint Regression, the spatial distribution of the mortality rate was done with the QGIZ Software version 2.18, and Spearman's correlation coefficient was used to correlate the mortality rates with the Human Development Index. RESULTS: There was an increase in breast cancer mortality rates in young women in the majority of Brazilian states, with an upward trend in all regions. The correlation with the Municipal Human Development Index, income, and education had a significant impact on the mortality rate for women from 30-39 years old in both time frames evaluated and for women from 20-29 years old, only from 1996 to 2000. CONCLUSION: The data obtained in the study, showed that even though the breast cancer mortality rate of young women is lower than women over 40 years old, it has been increasing in all regions of Brazil, mostly for women from 30-39 years old, suggesting that this group should be included in screening programs.
