Causes and investigation of stillbirths in Brazil: A multicentre cross-sectional study in 10 referral maternity hospitals.

OBJECTIVE: Understanding the local characteristics and statistics related to stillbirths may be the first step in a series of strategies associated with a reduction in stillbirth ratio. The aim of this study was to estimate the fetal mortality ratio and evaluate the investigation processes related to the causes of death, comparing the investigation according to the specific cause of death. METHODS: A cross-sectional study was retrospectively conducted in 10 tertiary obstetric care centers. Medical records of women with stillbirth managed between January 1, 2009 and December 31, 2018 were analyzed and classified, according to sociodemographic characteristics, and gestational and childbirth data, culminating in stillbirth. The stillbirth ratio and its causes were presented in proportions for the study period and individually for each health facility. RESULTS: Cases of 3390 stillbirths were analyzed. The stillbirth ratio varied from 10.74/1000 live births (LBs) in 2009 to 9.31/1000 in 2018. "Intrauterine hypoxia and asphyxia" (ICD-10 P20) and "unspecific causes of death" (ICD-10 P95) represented 40.8% of the causes of death. Investigation for TORCHS and diabetes occurred in 90.8% and 61.4% of deaths, respectively. Placental and necroscopic tests were performed in 36.6% of the cases. CONCLUSION: The adoption of a rational and standardized investigation of stillbirth remains an unmet need; the use of additional tests and examinations are lacking, especially when unspecific causes are attributed.

Causas Múltiplas de Morte Associadas à Parada Cardiorrespiratória Pediátrica de 1996 a 2019 no Brasil / Multiple Causes of Death Associated with Pediatric Cardiopulmonary Arrest from 1996 to 2019 in Brazil

Resumo Fundamento: Em pediatria, a parada cardiorrespiratória (PCR) está associada a alta mortalidade e graves sequelas neurológicas. Informações sobre as causas e mecanismos de morte abaixo de 20 anos poderiam fornecer subsídios teóricos para a melhoria da saúde de crianças e adolescentes. Objetivos: Realizar uma análise populacional das taxas de mortalidade por causas primárias e múltiplas de morte abaixo de 20 anos, em ambos os sexos, no período de 1996 a 2019, no Brasil, e identificar a frequência com que a PCR foi registrada nas declarações de óbito (DOs) desses indivíduos e os locais de ocorrência dos óbitos, a fim de promover estratégias para melhorar a prevenção de mortes. Método: Estudo ecológico de séries temporais de óbitos em indivíduos menores de 20 anos, no período de 1996 a 2019, avaliando as taxas de mortalidade (TMs) e a mortalidade proporcional (MP) por causa básica de morte. Foram analisados os percentuais de PCR registrados em qualquer linha da DO e o local de ocorrência dos óbitos. Foram calculadas as TMs por 100 mil habitantes e a MP por causa básica de morte nos menores de 20 anos segundo sexo e faixa etária, os percentuais de óbito por causas básicas por faixa etária quando a PCR foi descrita em qualquer linha das Partes I e II da DO, e o percentual de óbitos por causas básicas segundo o local de ocorrência. Os dados foram retirados do DATASUS, IBGE e SINASC. Resultados: De 1996 a 2019, ocorreram 2.151.716 óbitos de menores de 20 anos, no Brasil, gerando uma taxa de mortalidade de 134,38 por 100 mil habitantes. A taxa de óbito foi maior entre os recém-nascidos do sexo masculino. Do total de óbitos, 249.334 (11,6%) tiveram PCR registrada em qualquer linha da DO. Especificamente, a PCR foi registrada 49.178 vezes na DO na faixa etária entre 1 e 4 anos e em 88.116 vezes entre 29 e 365 dias, correspondendo, respectivamente, a 26% e 22% dos óbitos nessas faixas etárias. Essas duas faixas etárias apresentaram as maiores taxas de PCR registradas em qualquer linha da DO. As principais causas básicas de óbito quando a PCR foi registrada na sequência de óbitos foram doenças respiratórias, hematológicas e neoplásicas. Conclusão: As causas perinatais e externas foram as principais causas de morte, com maior TM nos menores de 20 anos no Brasil de 1996 a 2019. Quando consideradas as causas múltiplas de morte, as principais causas primárias associadas à PCR foram as doenças respiratórias, hematológicas e neoplásicas. A maioria dos óbitos ocorreu no ambiente hospitalar. Melhor compreensão da sequência de eventos nesses óbitos e melhorias nas estratégias de ensino em ressuscitação cardiopulmonar pediátrica são necessárias.

Abstract Background: In pediatrics, cardiopulmonary arrest (CPA) is associated with high mortality and severe neurologic sequelae. Information on the causes and mechanisms of death below the age of 20 years could provide theoretical support for health improvement among children and adolescents. Objectives: To conduct a population analysis of mortality rates due to primary and multiple causes of death below the age of 20 years in both sexes from 1996 to 2019 in Brazil, and identify the frequency in which CPA was recorded in the death certificates (DCs) of these individuals and the locations where the deaths occurred, in order to promote strategies to improve the prevention of deaths. Method: Ecological time-series study of deaths below the age of 20 years from 1996 to 2019, evaluating the mortality rates (MRs) and proportional mortality (PM) by primary cause of death. We analyzed the percentages of CPA recorded in any line of the DC and the location where the deaths occurred. We calculated the MRs per 100,000 inhabitants and the PM by primary cause of death under the age of 20 years according to sex and age group, the percentages of death from primary causes by age group when CPA was described in any line of Parts I and II of the DC, and the percentage of deaths from primary causes according to their location of occurrence. We retrieved the data from DATASUS, IBGE, and SINASC. Results: From 1996 to 2019, there were 2,151,716 deaths below the age of 20 years in Brazil, yielding a mortality rate of 134.38 per 100,000 inhabitants. The death rate was highest among male neonates. Of all deaths, 249,334 (11.6%) had CPA recorded in any line of the DC. Specifically, CPA was recorded in 49,178 DCs between the ages of 1 and 4 years and in 88,116 of those between the ages of 29 and 365 days, corresponding, respectively, to 26% and 22% of the deaths in these age groups. These two age groups had the highest rates of CPA recorded in any line of the DC. The main primary causes of death when CPA was recorded in the sequence of death were respiratory, hematologic, and neoplastic diseases. Conclusion: Perinatal and external causes were the primary causes of death, with highest MRs under the age of 20 years in Brazil from 1996 to 2019. When multiple causes of death were considered, the main primary causes associated with CPA were respiratory, hematologic, and neoplastic diseases. Most deaths occurred in the hospital environment. Better understanding of the sequence of events in these deaths and improvements in teaching strategies in pediatric cardiopulmonary resuscitation are needed.

Ischemic heart disease-related mortality in Brazil, 2006 to 2020. A study of multiple causes of death.

CONTEXT: Both the aging of the population and the increase in noncommunicable diseases may influence the progression and outcomes culminating in death, changing the evolution of ischemic heart diseases (IHDs) and their associated causes. Using the multiple causes of death method could help understand the magnitude of these relationships and enable better targeting of investments in health. OBJECTIVES: To evaluate the mortality from IHD in Brazil between 2006 and 2020 using the method of multiple causes and identify differences in the distribution pattern of IHD mortality by sex and geographic region. METHODS: Based on information extracted from death certificates (DCs) obtained from the database of the Department of Informatics of the Unified Health System (DATASUS), we used the multiple causes method to analyze the causes of death associated with IHD when IHD was defined as the underlying cause of death (UC) and the causes of death listed as the UC when IHD was recorded in any other lines of the DC, from 2006 to 2020, in Brazil. Subsequently, the proportion of these causes of death and differences between sexes and geographic regions were evaluated, with statistical relevance analyzed using the chi-square test, and the dependence between factors illustrated using stacked bar charts and small-world network graphs. RESULTS: When IHD was listed as the UC of death, the most frequent associated causes of death were, in descending order of frequency, acute myocardial infarction (AMI), arterial hypertension (AH), chronic ischemic heart disease (CHID), heart failure (HF), and diabetes mellitus (DM). When IHD was mentioned in any line of the DC, the most frequent UCs of death were AMI followed by DM, CIHD, chronic obstructive pulmonary disease (COPD), stroke, dyslipidemia, and, in the year 2020, COVID-19. The most frequent cause of death in women were DM as the UC and associated cause of death, AH as the UC, and CIHD and Alzheimer's disease as associated causes of death, while the most frequent causes of death in men were substance dependence as the UC and associated cause of death, and cancer as an associated cause of death. The most frequent causes of death were DM and stroke in the North and Northeast, dyslipidemia and obesity in the Midwest, Alzheimer's disease in the South and Southeast, and atherosclerotic heart disease (AHD) and COPD in the South. CONCLUSIONS: Several diseases - including AMI, AH, CIHD, HF, and DM - were the most frequent associated causes of death when IHD was recorded as the UC. In contrast, AMI, DM, CIHD, COPD, and stroke were the most frequent UCs when IHD was listed as an associated cause of death. The degree of these associations varied between sexes and geographic regions.

Impacto directo e indirecto del COVID-19 en la esperanza de vida al nacer de Chile en el año 2020 / Direct and indirect impact of COVID-19 on life expectancy at birth in Chile in 2020 / Impacto direto e indireto da COVID-19 na expectativa de vida ao nascer no Chile em 2020

Resumen: El artículo muestra el impacto directo e indirecto del COVID-19 en la esperanza de vida de Chile durante el año 2020, utilizando las estadísticas de defunciones definitivas publicadas en marzo del año 2023. Para ello, se estimó una mortalidad contrafactual para año 2020 sin el COVID-19, siguiendo el patrón de mortalidad según causas de muerte desde 1997 a 2019, se elaboraron tablas de mortalidad para calcular la esperanza de vida para los años 2015 a 2020 y para el año 2020 estimado, y luego se descompuso la diferencia entre la esperanza de vida esperada y observada del año 2020 según grupos de edad y causas de muerte. La esperanza de vida del año 2020 quiebra la tendencia a su aumento entre 2015 y 2019, mostrando un retroceso, en hombres y en mujeres, con respecto al año 2019, de 1,32 y 0,75 años respectivamente. Con respecto al año 2020 estimado, la esperanza de vida del 2020 observado es 1,51 años menor en hombres y 0,92 en mujeres, pero el impacto directo del COVID-19 en pérdida de esperanza de vida fue mayor, 1,89 para los hombres y 1,5 para las mujeres, concentrándose en las edades entre los 60 y 84 años en hombres y entre 60 y 89 años en mujeres. El impacto directo negativo del COVID-19 a la esperanza de vida en parte fue contrarrestado por impactos indirectos positivos significativos en dos grupos de causas de muerte, las enfermedades del sistema respiratorio y las enfermedades infecciosas y parasitarias. El estudio muestra la necesidad de distinguir los impactos directos e indirectos del COVID-19, por la incidencia que pueden tener en la salud pública cuando el COVID-19 baje su intensidad y se eliminen las restricciones de movilidad.

Abstract: This article shows the direct and indirect impacts of COVID-19 on life expectancy in Chile in 2020, based on mortality statistics published in March 2023. To this end, a counterfactual mortality was estimated for 2020 without COVID-19; based on the pattern of mortality by cause of death from 1997 to 2019, mortality charts were created to calculate life expectancy from 2015 to 2020 and an estimation for 2020, and the difference between expected and observed life expectancy in 2020 was then separated by age group and cause of death. Life expectancy in 2020 interrupted the upward trend from 2015 to 2019, showing a decline of 1.32 years in men and 0.75 years in women compared to 2019. Compared to the estimated 2020, life expectancy was 1.51 years lower in men and 0.92 years lower in women, but the direct impact of COVID-19 on the decrease in life expectancy was greater (1.89 for men and 1.5 for women) in the 60-84 age group in men and the 60-89 age group in women. The direct negative impact of COVID-19 on life expectancy was partially mitigated by significant positive indirect impacts on two groups of causes of death: diseases of the respiratory system and infectious and parasitic diseases. This study shows the need to differentiate direct and indirect impacts of COVID-19, due to the implications for public health when the intensity of COVID-19 decreases and mobility restrictions are suspended.

Resumo: Este artigo apresenta os impactos direto e indireto da COVID-19 na expectativa de vida no Chile em 2020 a partir de estatísticas de mortalidade publicadas em março de 2023. Para tanto, foi estimada uma mortalidade contrafactual para 2020 sem a COVID-19; a partir do padrão de mortalidade por causa de morte de 1997 a 2019, foram criadas tabelas de mortalidade para calcular a expectativa de vida para o período de 2015 a 2020 e para o ano estimado de 2020 e, em seguida, a diferença entre a expectativa de vida esperada e observada em 2020 foi separada por faixa etária e causa de morte. A expectativa de vida em 2020 interrompe a tendência de aumento entre 2015 e 2019, mostrando um declínio com relação a 2019 de 1,32 ano nos homens e 0,75 ano nas mulheres. Com relação ao ano estimado de 2020, a expectativa de vida observada é 1,51 ano menor nos homens e 0,92 nas mulheres, mas o impacto direto da COVID-19 na diminuição da expectativa de vida foi maior (1,89 para homens e 1,5 para mulheres), concentrando-se nas idades entre 60 e 84 anos nos homens e entre 60 e 89 anos nas mulheres. O impacto direto negativo da COVID-19 na expectativa de vida foi parcialmente atenuado por impactos indiretos positivos significativos em dois grupos de causas de morte: doenças do sistema respiratório e doenças infecciosas e parasitárias. Este estudo mostra a necessidade de diferenciar impactos diretos e indiretos da COVID-19, devido às implicações para a saúde pública quando a intensidade da COVID-19 diminuir e as restrições de mobilidade forem suspensas.

Survival and mortality profile among people living with HIV in a cohort in the Northeastern region of Brazil

ABSTRACT Conditions related to the acquired immune deficiency syndrome (AIDS) are still a significant cause of morbidity and mortality among people living with HIV (PLHIV). Longer survival in this population were reported to increase the risk of developing noncommunicable chronic diseases (NCDs). This study aimed to estimate the survival and causes of death according to age group and sex among PLHIV monitored at two referral centers in the Northeastern Brazil. This is a prospective, retrospective cohort with death records from 2007 to 2018, based on a database that registers causes of death using the International Classification of Disease (ICD-10), which were subsequently coded following the Coding Causes of Death in HIV (CoDe). A total of 2,359 PLHIV participated in the study, with 63.2% being men, with a follow-up period of 13.9 years. Annual mortality rate was 1.46 deaths per 100 PLHIV (95% CI: 1.33 - 1.60) with a frequency of 20.9%. Risk of death for men increased by 49% when compared to women, and the risk of death in PLHIV increased by 51% among those aged 50 years and over at the time of diagnosis. It was observed that 73.5% accounted for AIDS-related deaths, 6.9% for non-AIDS defining cancer, 6.3% for external causes, and 3.2% for cardiovascular diseases. Among the youngest, 97.2% presented an AIDS-related cause of death. Highest frequency of deaths from neoplasms was among women and from external causes among men. There is a need for health services to implement strategies ensuring greater adherence to treatment, especially among men and young people. Moreover, screening for chronic diseases and cancer is essential, including the establishment of easily accessible multidisciplinary care centers that can identify and address habits such as illicit drug use and alcoholism, which are associated with violent deaths.

Avoidability and temporal trend of neonatal mortality in Niteroi/RJ, 2012 to 2022 / Evitabilidade e tendência temporal da mortalidade neonatal em Niterói/RJ, 2012 a 2022

Abstract Objectives: to analyze neonatal deaths according to avoidability and to analyze the temporal trend of neonatal mortality rate (NMR) in Niterói/RJ, 2012-2022. Methods: ecological time series study. Data from Sistema de Informação sobre Nascidos Vivos and Sistema de Informação sobre Mortalidade. NMRs were calculated according to maternal and neonatal variables and trends were estimated using the joinpoint regression. Results: the annual number of live births (LB) fell, with a decreasing trend among adolescents and those with low education level. Of the 324 deaths, most occurred early (0-6 days), by preventable causes in 68.6%, predominating those reducible by adequate care during pregnancy. The overall NMR remained stable, ranging from 4.2 to 6/1,000 LB, being higher at the extremes of maternal age (12.7 and 8.6/1,000 LB in 2022, adolescents and over 35 years old, respectively), in low education level mothers (27.6/1,000 LB in 2022), in neonates <1,500g and <32 weeks (293.1 and 250/1,000 LB in 2022, respectively). NMR trend was upward in low schooling women, white-colored, adolescents and those ≥35 years, in babies weighing <1,500g and >2,500g, and for avoidable causes. Conclusions: the high proportion of preventable causes reveals the reduction potential. There was inequality in NMR and its trend, demanding more equitable health actions.

Resumo Objetivos: analisar os óbitos neonatais segundo evitabilidade e a tendência temporal da taxa de mortalidade neonatal (TMN) em Niterói/RJ, de 2012-2022. Métodos: estudo ecológico de série temporal. Dados provenientes do Sistema de Informações sobre Nascidos Vivos e Sistema de Informação sobre Mortalidade. As TMN foram calculadas segundo variáveis maternas e neonatais e as tendências estimadas pela regressão joinpoint. Resultados: o número anual de nascidos vivos (NV) diminuiu, com tendência decrescente entre mães adolescentes e de baixa escolaridade. Dos 324 óbitos, a maioria ocorreu precocemente, por causas evitáveis (68,6%), predominando aquelas reduzíveis por adequada atenção à gestação. A TMN global mostrou estabilidade, entre 4,2 e 6,0/1000NV, mais elevada nos extremos etários maternos (12,7 e 8,6/1.000 NV em 2022, adolescentes e maiores de 35 anos, respectivamente), nas mães com baixa escolaridade (27,6/1.000 NV em 2022), nos neonatos <1.500g e <32 semanas (293,1 e 250/1.000 NV em 2022, respectivamente). A tendência da TMN foi crescente entre mulheres de baixa escolaridade, brancas, adolescentes e ≥35 anos, nas faixas de peso <1.500g e >2.500g, e por causas evitáveis. Conclusões: a elevada proporção de causas evitáveis revela o potencial de redução. Houve desigualdade da TMN e sua tendência, demandando ações de saúde mais equânimes.

Pronóstico de defunciones según enfermedad crónica de pacientes ingresados en un hospital público / Prognosis of Deaths According to Chronic Disease of Patients Admitted to a Public Hospital

Introducción: Las enfermedades crónicas repercuten en gran medida en la calidad de vida de los pacientes, ya sea por sus características inherentes o por las complicaciones derivadas que ocasionan emergencias recurrentes. Objetivo: Pronosticar los días de hospitalización hasta el desenlace de pacientes con enfermedad crónica ingresados en un hospital público peruano. Métodos: Se realizó una investigación descriptiva, retrospectiva y transversal, entre julio y agosto del 2022, con 488 pacientes con enfermedad crónica ingresados en el Hospital Regional Docente de Cajamarca. Los datos demográficos de ingreso y el tipo de diagnóstico de los pacientes fueron proporcionados por la oficina de estadística del hospital. El análisis univariado se realizó con distribuciones absolutas y relativas, junto a sus intervalos de confianza al 95 por ciento y la relación pronóstica con Log Rank (Mantel-Cox) - ji al cuadrado, análisis de supervivencia de Kaplan-Meier (p < 0,05) y tablas de mortalidad. Resultados: El 53,1 por ciento de pacientes fueron mujeres, con 67,1 años de edad promedio, ingresaron al hospital por el servicio de emergencia (66,0 por ciento) y la enfermedad crónica fue la causa principal (79,1 por ciento). El promedio de hospitalización fue de 67,5 días, con mayor número en la hipertensión arterial (63 días), las diferencias numéricas en el tiempo de hospitalización según enfermedad crónica no se reflejan a nivel estadístico (p = 0,130). Las defunciones ocurrieron dentro del primer mes de hospitalización. Conclusión: Los días de hospitalización hasta el desenlace no son independientes de la enfermedad crónica de los pacientes, pues en ambos casos pueden ocurrir defunciones si sus características clínicas son irrecuperables(AU)

Introduction: Chronic diseases greatly impact the quality of life of patients, either due to their inherent characteristics or due to the derived complications that cause recurrent emergencies. Objective: To predict the days of hospitalization until the outcome of patients with chronic disease admitted to a Peruvian public hospital. Methods: A descriptive, retrospective and cross-sectional investigation was carried out from July to August 2022, with 488 patients with chronic disease admitted to Cajamarca Regional Teaching Hospital. Admission demographic data and type of patient diagnosis were provided by the hospital statistics office. The univariate analysis was performed with absolute and relative distributions, along with their 95percent confidence intervals and the prognostic relationship with Log Rank (Mantel-Cox) - chi square, Kaplan-Meier survival analysis (p < 0.05) and mortality tables. Results: 53.1percent of patients were women, with average age of 67.1 years, who were admitted to the hospital through the Emergency Service (66.0percent) and chronic disease was the main cause (79.1percent). The average hospitalization time was 67.5 days, with greater number in high blood pressure (63 days). The numerical differences in hospitalization time, according to chronic disease, are not reflected at a statistical level (p = 0.130). Deaths occurred within the first month of hospitalization. Conclusion: The days of hospitalization until the outcome are not independent of the patients' chronic illness, since in both cases deaths can occur if their clinical characteristics are irrecoverable(AU)

Caracterización de la mortalidad por diabetes mellitus en la provincia Cienfuegos durante los primeros nueve meses del 2020

Fundamento: según la Organización Mundial de la Salud la diabetes causa 300 000 muertes al año en América Latina y el Caribe y en la provincia Cienfuegos desde el año 2020 se ubica como séptima causa de fallecimientos. Objetivo caracterizar la mortalidad por diabetes mellitus en la provincia Cienfuegos en los primeros nueve meses del año 2020. Métodos: se realizó una investigación en sistemas y servicios de salud de tipo descriptiva a partir de una serie de casos para caracterizar la mortalidad por diabetes mellitus en Cienfuegos en los primeros nueve meses del año 2020. Los fallecidos se compilaron teniendo en cuenta: sexo, edad, color de la piel, nivel de escolaridad, lugar de residencia, estrato territorial, enfermedad, factores de riesgo asociados y causas de muertes directas. Se emplearon la media aritmética y la desviación estándar. Los resultados se presentan en forma de tablas y gráficos. Resultados la mayor afectación estuvo en las últimas décadas de la vida para el género femenino, así como la residencia en un territorio urbano, están entre las primeras causas directas de muerte el tromboembolismo pulmonar, así como la insuficiencia renal crónica agudizada, se destaca el desequilibrio hidroelectrolítico en un número considerable de las defunciones. Conclusiones las últimas décadas de la vida fueron las más afectadas y el sexo femenino, las principales causas de muerte fueron: el tromboembolismo pulmonar y la insuficiencia renal crónica agudizada. El desequilibrio hidroelectrolítico sobresale en un considerable número de los fallecidos.

Foundation: according to the World Health Organization, diabetes causes 300,000 deaths a year in Latin America and the Caribbean and in the Cienfuegos province since 2020 it ranks as the seventh cause of death. Objective: to characterize mortality from diabetes mellitus in the Cienfuegos province in the first nine months of 2020. Methods: a descriptive investigation was carried out on health systems and services based on a series of cases to characterize mortality from diabetes mellitus in Cienfuegos in the first nine months of 2020. The deceased were compiled taking into account: sex, age, skin color, educational level, place of residence, territorial stratum, disease, associated risk factors and direct causes of death. The arithmetic mean and standard deviation were used. The results are presented in the form of tables and graphs. Results: the greatest affectation was in the last decades of life for the female gender, as well as residence in an urban territory, among the first direct causes of death are pulmonary thromboembolism, as well as acute chronic renal failure; hydroelectrolytic imbalance stands out in a considerable number of deaths. Conclusions: the last decades of life were the most affected and the female sex, the main causes of death were: pulmonary thromboembolism and acute chronic renal failure. The hydroelectrolytic imbalance stands out in a considerable number of the deceased.

Complex Sex Differences in Life Expectancy in French Guiana.

In the complex context of French Guiana, different vulnerabilities and different risk factors between genders may lead to complex differences in health outcomes, mortality, and life expectancy. Our aim was, thus, to compare male and female mortality and life expectancy, to compare it between French Guiana and mainland France, and to look at temporal trends and the main specific causes of death in order to identify actionable singularities. National databases were used to obtain life expectancy at birth, at 20, 40, and 60 years, and mortality statistics. Standardized death rates and causes of death for French Guiana and mainland France were obtained through the CEPIDC, which analyzes information from death certificates. When comparing with mainland France, life expectancy at birth was significantly shorter both in males and females (mean = -2.9 years); life expectancy at 20 years, which allows to remove the effect of the greater child mortality in French Guiana, was also shorter in French Guiana for males (mean = -1.8 years) and females (mean = -2 years). The differences between mainland France and French Guiana regarding life expectancy at 40 and 60 years (mean = -1.5 and -1.3 years) was mainly found among females, males in French Guiana life expectancy at 40 and 60 years was closer to that in mainland France (mean = -0.8 and -0.6 years). Although they have a greater life expectancy at birth than men, women in French Guiana are substantially more affected by overweight/obesity and type 2 diabetes. The observed patterns of life expectancy at different ages presumably reflect the burden of external causes and AIDS in males and perhaps metabolic diseases in women.

Muerte accidental por consumo combinado de cocaína y etanol Revisión bibliográfica / Accidental death from combined cocaine and ethanol use. Literature review

La autopsia médico legal en Costa Rica, en casos sospechosos de intoxicación por cocaetileno se debe realizar bajo las normas establecidas en la Guía de estándares de trabajo para la Sección de Patología Forense del Departamento de Medicina Legal. El análisis del mecanismo fisiopatológico de cómo estas sustancias provocan alteraciones en el organismo que pueden conllevar a un eventual fallecimiento corresponde a parte del análisis requerido en la investigación ante la sospecha de esta causa de muerte. Por lo anterior, el objetivo de este artículo es describir los mecanismos fisiopatológicos que ocurren durante el consumo combinado de cocaína y etanol, los mecanismos que conllevan a la muerte de personas consumidoras de estas sustancias y las consideraciones médico legales a tomar en cuenta para el diagnóstico de esta causa de muerte. Se realizó revisión de artículos científicos, sobre los efectos del uso combinado de la cocaína y el etanol. La literatura describe que el uso combinado de cocaína y etanol potencia los efectos farmacocinéticos y bioquímicos de cada una de estas sustancias, que su derivado, el cocaetileno, es capaz de generar por sí mismo los mecanismos causantes de la muerte. Que los principales mecanismos fisiopatológicos que conllevan la muerte ante el uso combinado de estas sustancias son de origen cardiovascular y hepático. Como consideraciones médico legales a tomar en cuenta para el diagnóstico de esta manera de muerte accidental, en la Sección de Toxicología del Departamento de Ciencias Forenses de Costa Rica, la cuantificación del cocaetileno y las sustancias relacionadas no se realiza, aunque se encuentra actualmente en el desarrollo de un proyecto para la determinación de la estabilidad de las drogas en sangre bajo las condiciones de almacenamiento, con el fin de ofrecer la posibilidad de cuantificar ciertas drogas (en donde se podría incluir el cocaetileno) en un futuro próximo.

Medical-legal autopsy in Costa Rica, in suspected cases of cocaethylene poisoning must be performed under the regulations established in the Work Standards Guide for the Forensic Pathology Section of the Department of Legal Medicine. The analysis of the pathophysiological mechanism of how these substances cause alterations in the organism that can lead to eventual death corresponds to part of the analysis required in the investigation when this cause of death is suspected. Therefore, the objective of this article is to describe the pathophysiological mechanisms that occur during the combined consumption of cocaine and ethanol, the mechanisms that lead to the death of people who consume these substances, and the medico-legal considerations to be considered for the diagnosis. of this cause of death. A review of scientific articles was carried out on the effects of the combined use of cocaine and ethanol. The literature describes that the combined use of cocaine and ethanol enhances the pharmacokinetic and biochemical effects of each one of these substances, that its derivative, cocaethylene, can generate the mechanisms that cause death by itself. That the main pathophysiological mechanisms that lead to death in the combined use of these substances are of cardiovascular and hepatic origin. As legal medical considerations to take into account for the diagnosis of this type of accidental death, in the Toxicology Section of the Department of Forensic Sciences of Costa Rica, the quantification of cocaethylene and related substances is not carried out, although it is currently in the development of a project for the determination of the stability of drugs in blood under storage conditions, in order to offer the possibility of quantifying certain drugs (which could include cocaethylene) in the near future.

Excess mortality in a cohort of Brazilian patients with a median follow-up of 11 years after the first psychiatric hospital admission.

PURPOSE: To estimate the mortality rates of a cohort of Brazilian patients after their first psychiatric admission and determine the possible risk factors associated with excess mortality. METHODS: The study included a cohort of psychiatric patients hospitalised from Jan 1, 2002 to Dec 31, 2007 in the catchment area of Ribeirão Preto, São Paulo state, Brazil. Data were linked to deaths that occurred between Jan 1, 2002 and Dec 31, 2016 from the SEADE Foundation (state data analysis system of São Paulo). The mortality rate (MR), age-sex-standardised mortality ratio (SMR), life expectancy at birth, and years of life lost (YLL) were computed. The factors associated with mortality were analysed by survival analysis using a Cox proportional hazards regression model. RESULTS: Of 4019 patients admitted (54.76% male), 803 died (69.74% male) during the follow-up (median = 11.25 years). Mortality rates were approximately three-fold higher than expected (SMR = 2.90, 95% CI 2.71-3.11). The highest mortality rate was noted in men with alcohol-related disorders (SMR = 5.50, 95% CI 4.87-6.19). Male sex (adjusted hazard ratio (aHR) = 1.62, 95% CI 1.37-1.92), higher age (aHR = 21.47, 95% CI 13.48-34.17), and unemployment (aHR = 1.22, 95% CI 1.05-1.43) significantly increased the mortality risk from all causes. The average YLL was 27.64 years with the highest YLL noted in nonalcohol substance-related disorders (39.22 years). The life expectancy at birth in this cohort was 47.27 years. Unnatural causes of death were associated with nonwhite skin colour and substance-related disorders. CONCLUSION: An excess of mortality and a significant reduction in life expectancy of mentally disordered patients who were first admitted to psychiatric beds was noted, particularly patients admitted for substance-related disorders, which should represent a priority in mental health policies.

Diferenciais regionais da mortalidade no Brasil: contribuição dos grupos etários e de causas de óbito sobre a variação da esperança de vida e da dispersão da idade à morte entre 2008 e 2018 / Regional inequalities in mortality in Brazil: contributions of age and cause of death to changes in life expectancy and lifespan variation between 2008 and 2018 / Diferenciales regionales de mortalidad en Brasil: contribución de los grupos de edad y las causas de muerte en la variación de la esperanza de vida y la dispersión de la edad al morir entre 2008 y 2018

Resumo O Brasil é um país marcado por forte desigualdade socioeconômica entre as regiões, que, por sua vez, se traduz em diferenciais regionais de mortalidade. Para um bom monitoramento desses diferenciais, é importante uma análise não apenas dos níveis médios de mortalidade, mas também da variação da idade à morte na população. Esse artigo analisa a contribuição das causas de óbito sobre as mudanças na esperança de vida e na dispersão da idade à morte no Brasil e grandes regiões entre 2008 e 2018. Os resultados sugerem aumento dos diferenciais regionais na esperança de vida ao longo da década analisada. No entanto, as diferenças regionais na dispersão da idade à morte se mantiveram praticamente constantes. As mudanças na mortalidade por causa impactam de maneiras diferentes a dispersão da idade à morte em cada região: a redução da mortalidade por causas externas contribui substantivamente para diminuir a variação da idade à morte nas regiões Sul e Sudeste, enquanto a contribuição das mortes por afecções originadas no período perinatal foi substantiva apenas na região Nordeste. Por fim, reafirmamos a importância dos indicadores de dispersão da idade à morte para se ter uma visão mais ampla dos diferenciais regionais de mortalidade no Brasil.

Abstract Brazil is a country marked by substantial socioeconomic inequality among regions, which translates into regional differentials in mortality. For better monitoring these differentials, it is important to analyze not only population average mortality levels, but also the age at death variation. This article analyzes cause-of-death contributions to changes in life expectancy and age-at-death variation in Brazil and its regions between 2008 and 2018. Our results suggest an increase in regional inequalities in life expectancy over the decade. However, regional differences in age-at-death variation remained nearly constant. Changes in mortality by cause impact the age-at-death variation differently in each region: the reduction in mortality from external causes substantially contributed to decreasing the variation in age at death in the South and Southeast regions, whereas the contribution of deaths from conditions originating in the perinatal period was substantive only in the Northeast region. Finally, we reaffirm the importance of age-at-death dispersion indicators to have a broader view of Brazil's regional differentials in mortality.

Resumen Brasil es un país marcado por fuertes desigualdades socioeconómicas entre sus regiones, lo que traduce a su vez se en diferencias regionales en la mortalidad. Para un buen seguimiento de estos diferenciales es importante analizar no solo los niveles medios de mortalidad, sino también la variación de la edad de la muerte en la población. Este artículo analiza la contribución de los grupos de causas de defunción sobre los cambios en la esperanza de vida al nacer y la dispersión de la edad al morir en Brasil y las grandes regiones entre 2008 y 2018. Nuestros resultados sugieren un aumento de las diferencias regionales en la esperanza de vida a lo largo de la década. Sin embargo, las diferencias regionales en la dispersión de la edad al morir se mantuvieron prácticamente constantes. Los cambios en la mortalidad por causas repercuten de forma diferente en la dispersión de la edad al fallecer en cada región: la reducción de la mortalidad por causas externas contribuyó de forma sustantiva a disminuir la variación de la edad al morir en las regiones Sur y Sureste, mientras que la contribución de las muertes por afecciones originadas en el período perinatal fue sustantiva en la región Noreste. Por último, reafirmamos la importancia de los indicadores de dispersión de la edad al morir para tener una visión más general de los diferenciales regionales de mortalidad en Brasil.

Sex Differences in Cardiovascular Disease Mortality in Brazil between 1996 and 2019.

BACKGROUND: cardiovascular diseases (CVD) are Brazil's leading causes of death in women and men. This study analyzed age-adjusted death rate (DRaj) trends from all causes of death (ACD), CVD, ischemic heart disease (IHD), and stroke in women and men aged 35 to 74 years from 1996 to 2019. METHODS: We analyzed DRaj trends for all causes of death (ACD), CVD, IHD, and stroke. Data were from the Ministry of Health mortality database. Joinpoint Regression Program™ performed trend analysis and adjustments in death rates. Average annual percentage change (AAPC) determined the intensity of changes. RESULTS: In women, DRaj reduced for ACD (AAPC = -1.6%); CVD (AAPC = -2.6%); IHD (AAPC = -1.9%); and stroke (AAPC = -4.6%) (p < 0.001 for all). In men, ACD reduced from 1996 to 2004 (AAPC = -0.9%; p < 0.001), from 2012 to 2019 (AAPC = -1.9%; p < 0.001), and unchanged from 2004 to 2012; CVD (AAPC = -2.1%); IHD (AAPC = -1.5%); stroke (AAPC = -4.9%) (p < 0.001 for all) reduced from 1996 to 2019. From 1996 to 2019, the male/female ratio for ACD remained unchanged. CVD increased from 1.58 to 1.83, IHD from 1.99 to 2.30, and stroke from 1.52 to 1.83. CONCLUSION: ACD, CVD, IHD, and stroke were reduced more significantly in women, and the ratio of CVD, IHD, and CVD in men and women increased more in men. Future studies will be needed to determine the main factors responsible for a better outcome in women.

Causas de muerte de los fallecidos en hemodiálisis iterada / Causes of death in iterated hemodialysis

Introducción: La hemodiálisis es la terapia de remplazo renal más utilizada en Latinoamérica y en Cuba. Se calcula que para el año 2030 la cantidad de pacientes que inician el tratamiento de reemplazo renal a nivel mundial aumentará a más del 50 por ciento con respecto al año 2010. Objetivo: Caracterizar los pacientes en tratamiento de hemodiálisis iterada. Métodos: Se realizó un estudio descriptivo, transversal, de todos los pacientes en tratamiento de HDI del Instituto de Nefrología Dr. Abelardo Buch López (INEF), fallecidos en el período 2013-2018. Los datos se obtuvieron del registro de fallecidos, del registro de pacientes en hemodiálisis y de la historia clínica. El procesamiento fue realizado de forma automatizada (IBM Spss 22.0). Se calcularon tasas brutas de mortalidad y fue utilizada la técnica de análisis de distribución de frecuencias. Resultados: La tasa de mortalidad del período resultó ser 20,3 por cada 100 pacientes. El 60,9 por ciento de los pacientes fallecidos tenían entre 60 y 79 años de edad. La hipertensión arterial (HTA) fue la enfermedad de base más frecuente (55,5 por ciento), y la comorbilidad predominante (87,3 por ciento). El 53,6 por ciento de los pacientes fallecidos empleaba catéter venoso central, y el 70 por ciento tenía menos de 5 años en HD. La principal causa de muerte fue la enfermedad cardiovascular (46,4 por ciento). Conclusiones: En el INEF la mortalidad en hemodiálisis se comportó de manera estable. Similar a otros reportes de servicios de hemodiálisis, los fallecidos se caracterizaron en su mayoría por tener catéter venoso central para hemodiálisis y menos de cinco años en el tratamiento. Las causas de muerte presentaron el mismo patrón que las reportadas en análisis nacionales e internacionales(AU)

Introduction: Hemodialysis is the most used renal replacement therapy in Latin America and in Cuba. It is estimated that by the year 2030 the number of patients starting therapy worldwide will increase to more than 50 percent compared to 2010. Objectives: To characterize the patients undergoing iterated hemodialysis treatment. Methods: A descriptive, cross-sectional study of all patients undergoing repeated hemodialysis treatment, who deceased in the period 2013-2018 was carried out at Dr. Abelardo Buch López Institute of Nephrology. The processing was done in an automatically (IBM Spss 22.0). Gross mortality rates were calculated and the frequency distribution analysis technique was used. Results: The mortality rate for the period was 20.3 per 100 patients. 60.9percent of the deceased patients were between 60 and 79 years of age. Arterial hypertension was the most frequent underlying disease (55.5percent), and the predominant comorbidity (87.3percent). 53.6percent of the deceased patients used a central venous catheter, and 70percent had been on hemodialysis for less than 5 years. The main cause of death was cardiovascular disease (46.4percent). Conclusions: At Dr. Abelardo Buch López Institute of Nephrology mortality in hemodialysis behaved in a stable manner. Similar to other reports of hemodialysis services, the deceased were mostly characterized by having a central venous catheter for hemodialysis and less than five years in treatment. The causes of death showed the same pattern as those reported in national and international analyses(AU)

La hipertensión arterial como causa de muerte: causa básica vs causas múltiples. Cuba, 2013-2019 / Arterial hypertension as a cause of death: basic cause vs multiple causes. Cuba, 2013-2019

Introducción: Las tasas de mortalidad "por" hipertensión arterial subestiman el impacto de esta causa en la mortalidad. Objetivo: Determinar el cambio de la contribución de la hipertensión arterial como causa de muerte, al involucrar todas sus menciones en el certificado de defunción en Cuba en el periodo 2013-2019. Material y Métodos: Se realizó un estudio observacional descriptivo de las defunciones ocurridas en Cuba entre enero de 2013 y diciembre de 2019. Se calcularon las Tasas de Mortalidad "por" (causa básica) y "con" hipertensión arterial (causas múltiples). Además, se determinaron las causas básicas más asociadas a la mención de esta afección. Resultados: Los riesgos de morir "por" y "con" hipertensión arterial evidencian un ascenso. El segundo es, como promedio, cuatro veces mayor que el primero; lo que significa que el análisis de mortalidad "por· HTA continúa infravalorando el papel de esta afección dentro de los procesos que causan muerte. Ambos riesgos son mayores para hombres y para los adultos de 85 años y más. Como promedio, en 15,7 por ciento de las defunciones se mencionó a la HTA en alguna de las partes del certificado; sin embargo, solo en 3,8 por ciento fue declarada como causa básica. Las enfermedades cerebrovasculares y las del corazón son las dos causas básicas en las que la HTA es más frecuentemente causa asociada. Conclusiones: La contribución de la hipertensión arterial a la mortalidad es mayor a lo que traduce el análisis tradicional. Disponer de estimaciones de causas múltiples fortalecería la planificación en salud y potenciaría los análisis de carga de enfermedad(AU)

Introduction: Mortality rates "due to" arterial hypertension underestimate the impact of this cause on mortality. Objective: To determine the change in the contribution of arterial hypertension to the cause of death, by analyzing all its mentions in the death certificates in Cuba in the period 2013-2019. Material and Methods: A descriptive observational study of deaths that occurred in Cuba between January 2013 and December 2019 was carried out. Mortality rates "due to" (basic cause) and "with" arterial hypertension (multiple causes) were calculated. In addition, the most common underlying causes associated with the mention of this condition were determined. Results: The risks of dying "due to" and "with" arterial hypertension show an increase. The second risk is, on average, four times higher than the first one, which means that the analysis of mortality "due to" arterial hypertension continues to underestimate the role of this condition within the processes causing death. Both risks are higher for men and adults aged 85 years and older. On average, arterial hypertension was mentioned in some parts of the certificates in 15,7 percent of the deaths registered during the period; however, it was declared as the basic cause only in 3,8 percent of them. Cerebrovascular and heart diseases are the two underlying causes in which arterial hypertension is the most frequently associated cause. Conclusions: The contribution of arterial hypertension to mortality is greater than that identified in the traditional analysis. Having estimates of multiple causes would strengthen health planning and enhance the analyses of disease burden(AU)

Maternal mortality in South region of Brazil: an analysis from 2000 to 2018.

This study characterises maternal mortality in southern Brazil and verifies its trends between 2000 and 2018. It is an ecological time-series study, analysing secondary data from the Department of Informatics of the Unified Health System. The trend of the maternal mortality ratio (MMR) was calculated using generalised linear regression, and the ratios of the rates according to women's characteristics, with a confidence interval (CI) of 95%. The MMR in the South region went from 53.4 to 36.8 deaths per 100,000 live births from 2000 to 2018, a reduction trend of 1.2 percentage points per year. Mortality was directly related to increasing age (p < .001) and inversely related to schooling (p < .001) and predominated in non-white women (p < .001). The main cause of death was direct causes, including hypertensive disorders. Despite the reduction trend in maternal mortality in southern Brazil, the MMR observed is constantly above the recommended by the World Health Organisation.Impact StatementWhat is already known on this subject? The Maternal Mortality Ratio (MMR) is an indicator that allows an analysis of women's health in relation to the socio-economic and care characteristics of the region where they live. Between 2000 and 2015, Brazil had presented a high MMR, with around 50 deaths per 100,000 live births, while WHO considers a reasonably adequate MMR of fewer than 20 deaths per 100,000 live births.What do the results of this study add? This study updates data about MMR in the Southern Region of Brazil, the one which has the lowest rates in the country, but with variable values between the states. There was a reduction in MMR in southern Brazil between 2000 and 2018 but higher rates for women over 30 years old and in a situation of social vulnerability, as low-income and non-white women. Santa Catarina State presented stable values in the period and remained below the RMM averages of the other states during all years.What are the implications of these findings for clinical practice and/or further research? Comparing previous and current Maternal Mortality Rates in the regional context is important to adapt public health policies for the most affected population. Maternal death is still a reality for single and low-income women, who have greater difficulty in access to health care. Strategies in the Unified Health System are needed to tackle this problem.

Visión de las causas de muerte por la COVID-19 con las experiencias de las autopsias / Vision of the causes of death by COVID-19 with the experiences of autopsies

RESUMEN El 30 de enero de 2020, la Organización Mundial de la Salud declaró a la infección por SARS-CoV-2 una emergencia internacional de salud pública. La autopsia, considerada el mejor método de estudio del enfermo y la enfermedad, corrobora que los pacientes pueden morir por la acción directa del virus (fallecidos por la COVID-19), mientras que otros positivos al SARS-CoV-2, no mostraron cambios morfológicos pulmonares atribuidos a la acción del virus. Se propone establecer los criterios diagnósticos morfológicos en el contexto de la epidemia por el SARS-CoV-2 y la COVID-19 en los fallecidos en Cuba, a partir del estudio sistemático de las autopsias. Se han identificado los patrones morfológicos que se establecen en los pulmones de los pacientes fallecidos bajo el efecto de la COVID-19. El edema pulmonar de permeabilidad con el ensanchamiento de tabique pulmonar, el depósito de la membrana hialina desorganizada en el interior de los alveolos, el desprendimiento de células epiteliales (neumocitos y células bronquiales y bronquiolares), seguida de la hiperplasia epitelial con presencia en ocasiones de cambios metaplásicos y atipias, y finalmente, la fibrosis. Cuando se realizan autopsias, es posible ubicar cada enfermedad en su lugar, en el cronopatograma, lo que permite realizar el reparo de los certificados de defunción, para evaluar el lugar que la COVID-19 ha ocupado como causa de muerte en la población estudiada. En criterio del colectivo, identificar en las alteraciones morfológicas, es imprescindible para elaborar el cronopatograma del fallecido y la adecuada evaluación clínico patológica del paciente.

ABSTRACT On January 30, 2020, the World Health Organization (WHO) declared SARS-CoV-2 infection an international public health emergency. The autopsy, considered the best method of studying the patient and the disease, corroborates that patients can die from the direct action of the virus (who died from COVID-19), while others positive for SARS-CoV-2 did not show morphological lung changes attributed to the action of the virus. It is proposed to establish the morphological diagnostic criteria in the context of the SARS-CoV-2 and COVID-19 epidemic in the deceased in Cuba based on the systematic study of autopsies. The morphological patterns that are established in the lungs of patients who died under the effect of COVID-19 have been identified. The pulmonary edema of permeability with the widening of the pulmonary septum, the deposit of the disorganized hyaline membrane inside the alveoli, the detachment of epithelial cells (pneumocytes and bronchial and bronchiolar cells), followed by epithelial hyperplasia with sometimes the presence of metaplastic changes and atypia, and finally, fibrosis. When autopsies are performed, it is possible to locate each disease in its place, in chronopathogram, which allows death certificates repair to be carried out to assess the place that COVID-19 has occupied as a cause of death in the population studied. In the opinion of the group, identifying morphological alterations is essential to prepare the chronopathogram of the deceased and the adequate clinical-pathological evaluation of the patient.

Causas de muerte en pacientes con cáncer colorrectal en el quinquenio 2016-2020. Colón, Matanzas

RESUMEN Introducción: el cáncer colorrectal constituye la tercera causa de muerte por tumores malignos en Cuba. Su estadio en el momento del diagnóstico es el predictor más importante de supervivencia, por lo que al analizar las causas de muerte se puede conocer la precocidad en su detección. Objetivo: determinar las principales causas de muerte de los pacientes fallecidos por cáncer colorrectal. Materiales y métodos: se realizó un estudio descriptivo retrospectivo de las causas de muerte en 149 pacientes con cáncer colorrectal como causa primaria de muerte en el municipio de Colón, entre el 1 de enero de 2016 y el 31 de diciembre de 2020, notificados en el Registro de Fallecidos de la Dirección Municipal de Salud. Las variables independientes utilizadas fueron: sexo, grupos etarios, edad, causa directa de muerte, causa de sepsis. Resultados: predominó el sexo femenino en los pacientes fallecidos por cáncer colorrectal (53 %). La mortalidad se incrementó a partir de los 60 años de edad (124 pacientes, para un 83,2 %). La causa directa de muerte predominante fue la toxemia cancerígena (61,1 %), seguida de la sepsis (28,1 %) y el tromboembolismo pulmonar (3,4 %). Conclusiones: las causas de muerte de los pacientes con cáncer colorrectal en el municipio Colón, en el quinquenio 2016-2020, fueron indicativas de enfermedad neoplásica en estadio avanzado y de diagnóstico tardío.

ABSTRACT Introduction: colorectal cancer is the third cause of death due to malignant cancer in Cuba. Its stage at the time of diagnosis is the most important predictor of survival, so when analyzing the causes of death it is possible to know the precocity in its detection. Objective: to determine the main causes of death in patients who died of colorectal cancer. Materials and methods: a retrospective descriptive study of the causes of death was carried out in 149 patients with colorectal cancer as the primary cause of death in the municipality of Colon, between January 1, 2016 and December 31, 2020, recorded in the Death Registry of the Municipal Health Directorate. The independent variables used were: gender, age groups, age, direct cause of death, cause of sepsis. Results: female sex predominated in patients who died due to colorectal cancer (53 %). Mortality increased after the age of 60 years (124 patients, for 83.2 %). The predominant direct cause of death was carcinogenic toxemia (61.1 %), followed by sepsis (28.1 %) and pulmonary thromboembolism (3.4 %). Conclusions: the causes of death of patients with colorectal cancer in the municipality of Colón in the five-year period 2016-2020 period were indicative of advanced stage neoplastic disease and late diagnosis.
