Mortality related to sickle cell disease and COVID-19 in Brazil, 2020

SUMMARY OBJECTIVE: The ability to cause death is the definitive measure of an infectious disease severity, particularly one caused by a novel pathogen like severe acute respiratory syndrome-CoV-2 (COVID-19). This study describes sickle cell disease-related mortality issues during the COVID-19 pandemic in Brazil. METHODS: The provisional 2020 mortality data originated from the public databases of the Mortality Information System and were investigated using the multiple-cause-of-death methodology. RESULTS: In 2020, 688 sickle cell disease-related deaths occurred, of which 422 (61.3%) had an underlying cause of death and 266 (38.7%) had an associated cause of death. Furthermore, 98 COVID-19-related deaths occurred, of which 78 were underlying cause of death among sickle cell disease associated (non-underlying) cause of death. Sickle cell disease-related deaths occurred mostly among young adults aged 25-49 years. COVID-19 deaths occurred at ages older than among sickle cell disease-related deaths. Majority of deaths happened in the southeast (42.3%) and northeast regions (34.0%), while COVID-19 deaths prevailed in the northeast region (42.9%). Regarding overall deaths, the leading underlying cause of death was sickle cell disease itself, followed by infectious and parasitic diseases (14.8%), owing to COVID-19 deaths, and diseases of the circulatory system (8.9%). Next, in males, diseases of the digestive system (4.8%) occurred, while, in females, maternal deaths succeeded, included in the chapter on pregnancy, childbirth, and the puerperium, accounting for 5.9% of female deaths. The leading overall associated (non-underlying) cause of deaths were septicemias (29.4%), followed by respiratory failure (20.9%), pneumonias (18.3%), and renal failure (14.7%). CONCLUSION: In Brazil, COVID-19 deaths produced trend changes in sickle cell disease-related causes of death, age at death, and regional distribution of deaths in 2020.

Pulmonary Heart Disease Associated Mortality - China, 2014-2021.

Introduction: Over the latter half of the previous century, pulmonary heart disease (PHD) emerged as a significant public health issue in China. However, the current mortality rate is unknown. Utilizing the Multiple Cause of Death database, the present study aims to investigate the current state and progression of PHD-associated death in China. Methods: Data from the China National Mortality Surveillance System were used to analyze progression in mortality rates attributable to PHD from 2014 to 2021. To standardize population structure for each year during the investigation period, demographic information from the 2020 census was employed as the reference population. Age-standardized mortality rates (ASMR) were determined based on sex, urban-rural area, and region. To identify trends in ASMR, a joinpoint regression analysis was executed. Results: The ASMR of PHD exhibited a marked decrease, falling from 61.68 per 100,000 in 2014 to 28.53 per 100,000 in 2021. This downward trend was observable in both genders, all regions, and both urban and rural settings. The greatest ASMR values were documented in the western region. Comparative observations revealed a higher ASMR in rural areas versus urban ones and in males versus females. PHD-associated deaths predominantly occurred among older individuals, particularly those aged 80 and above. Chronic obstructive pulmonary disease (COPD) emerged as the principal underlying cause of death PHD-associated mortalities, accounting for between 87.41% and 93.42% of cases throughout the period 2014-2021. Conclusions: There was a declining trend in PHD mortality in China from 2014 to 2021, with COPD accounting for a significant proportion of these deaths. Given the high prevalence of COPD and the escalating population aging in China, PHD remains a significant health concern that warrants further attention.

Mortality Associated with Idiopathic Pulmonary Fibrosis in Northeastern Italy, 2008-2020: A Multiple Cause of Death Analysis.

Mortality from idiopathic pulmonary fibrosis (IPF) is increasing in most European countries, but there are no data for Italy. We analysed the registry data from a region in northeastern Italy to assess the trends in IPF-related mortality during 2008-2019, to compare results of underlying vs. multiple cause of death analyses, and to describe the impact of the COVID-19 epidemic in 2020. We identified IPF (ICD-10 code J84.1) among the causes of death registered in 557,932 certificates in the Veneto region. We assessed time trends in annual age-standardized mortality rates by gender and age (40-74, 75-84, and ≥85 years). IPF was the underlying cause of 1310 deaths in the 2251 certificates mentioning IPF. For all age groups combined, the age-standardized mortality rate from IPF identified as the underlying cause of death was close to the European median (males and females: 3.1 and 1.3 per 100,000/year, respectively). During 2008-2019, mortality rates increased in men aged ≥85 years (annual percent change of 6.5%, 95% CI: 2.0, 11.2%), but not among women or for the younger age groups. A 72% excess of IPF-related deaths was registered in March-April 2020 (mortality ratio 1.72, 95% CI: 1.29, 2.24). IPF mortality was increasing among older men in northeastern Italy. The burden of IPF was heavier than assessed by routine statistics, since less than two out of three IPF-related deaths were directly attributed to this condition. COVID-19 was accompanied by a remarkable increase in IPF-related mortality.

The Persistence of Underreporting of Hepatitis C as an Underlying or Contributing Cause of Death, 2011-2017.

Using electronic health records, we found that hepatitis C virus (HCV) reporting on death certificates of 2901 HCV-infected decedents from 4 US healthcare organizations during 2011-2017 was documented in only 50% of decedents with hepatocellular carcinoma and less than half with decompensated cirrhosis. National figures likely underestimate the US HCV mortality burden.

Covid Adult Mortality in Brazil: An Analysis of Multiple Causes of Death.

Objective: This study aimed to analyze the chain of events and contributing causes associated with COVID-19 adult mortality (30-69 years old), based on qualified data on CoD from three Brazilian capitals cities, Belo Horizonte, Salvador, and Natal, in 2020. Methods: Data of all deaths among residents in the three capitals in 2020 were provided by these municipalities' routine Mortality Information System (SIM). Mentions B34.2 with the markers U07.1 and U07.2 in the death certificate identified COVID-19 deaths. We used a multiple-cause-of-death approach better to understand the complexity of the morbid process of COVID-19. Conditions that appeared more frequently in the same line or above the COVID-19 mentions in the death certificate were considered a chain-of-event. Conditions that occurred more often after the codes for COVID-19 were considered as contributing. Results: In 2020, 7,029 records from COVID-19 as the underlying cause of death were registered in SIM in the three capitals. Among these, 2,921 (41.6%) were deceased between 30 and 69 years old, representing 17.0% of deaths in this age group. As chain-of-events, the most frequent conditions mentioned were sepsis (33.4%), SARS (32.0%), acute respiratory failure (31.9%), unspecified lower respiratory infections (unspecified pneumonia) (20.1%), and other specified respiratory disorders (14.1%). Hypertension (33.3%), diabetes unspecified type (21.7%), renal failure (12.7%), obesity (9.8%), other chronic kidney diseases (4.9%), and diabetes mellitus type 2 (4.7%) were the most frequent contributing conditions. On average, 3.04 conditions were mentioned in the death certificate besides COVID-19. This average varied according to age, place of death, and capital. Conclusion: The multiple-cause analysis is a powerful tool to better understand the morbid process due to COVID-19 and highlight the importance of chronic non-communicable diseases as contributing conditions.

Animal-Encounter Fatalities, United States, 1999-2016: Cause of Death and Misreporting.

OBJECTIVES: Errors and misreporting on death certificates are common, along with potential inaccuracies in cause-of-death coding. We characterized and compared fatalities by animal-encounter mentions reported as underlying cause of death (UCD) with animal-encounter mentions reported as multiple cause of death (MCD) to determine factors associated with misreporting UCD. METHODS: We analyzed fatality data from 1999-2016 from the Centers for Disease Control and Prevention Wide-ranging ONline Data for Epidemiologic Research by UCD and MCD animal-encounter mentions (International Classification of Diseases, 10th Revision codes W53-59, X20-27 and X29, T63.0-63.6, T63.8-63.9, and T78.2-78.4). We examined differences in reporting by age, sex, race, autopsy (yes, no, unknown), allergic reactions, and toxicities. RESULTS: The number of animal-encounter mentions by UCD was 3638 (202 average per year) and by MCD was 4280 (238 average per year), a difference of 18% (n = 642; 36 average per year) by MCD analysis. The number of nonvenomous animal-encounter mentions increased 20% (from 2138 UCD to 2567 MCD), and the number of venomous animal-encounter mentions increased 14% (from 1500 UCD to 1713 MCD). Decedents aged ≥65 had the highest additional number of animal-encounter mentions among all age groups, primarily encounters with other reptiles (n = 113), other mammals (n = 71), and dogs (n = 42). Of 642 MCD additional animal-encounter mentions, heart disease (n = 211, 33%) and infections (n = 146, 23%) represented more than half of the UCD. Of 553 dog-encounter fatalities, 165 (30%) were among children aged ≤4. CONCLUSIONS: Animal-encounter fatalities, analyzed by UCD alone, may be underreported. An initiating animal injury, complicated by comorbidities and fatality, may obscure the causal chain, resulting in misreporting UCD. Ongoing training for medical certifiers is recommended, highlighting accurate identification of UCD and contributing causes in the causal chain of death.

Excess liver-related mortality among people with AIDS compared to the general population: an Italian nationwide cohort study using multiple causes of death.

OBJECTIVES: Liver diseases have become a leading cause of death among people with AIDS (PWA). This study aimed to investigate whether PWA experienced excess mortality related to liver diseases as compared to the general population (non-PWA), using a multiple cause of death (MCoD; i.e. all conditions reported on death certificates) approach. METHODS: A population-based, nationwide, retrospective cohort study was conducted among Italian people, aged 15-74 years, who had been diagnosed with AIDS since 2006. Date of death and MCoD data were retrieved, up to December 2015, by individual record linkage with national mortality data. Sex- and age-standardized mortality ratios (SMRs), with 95% confidence intervals (CIs), were estimated by dividing the observed number of deaths related to a specific condition among PWA to the expected number, based on non-PWA mortality rates. RESULTS: Among 7912 PWA (34 184 person-years), 2076 deaths occurred. The number of death certificates reporting liver diseases among MCoDs was 583 (28.1%), including 382 (18.4%) reporting viral hepatitis, 370 (17.8%) reporting nonviral liver diseases, and 41 (2.0%) reporting liver cancers. The corresponding SMRs were 40.4 (95% CI 37.2-43.8) for all liver diseases, 131.1 (95% CI 118.3-145.0) for viral hepatitis, 29.9 (95% CI 27.0-33.1) for nonviral liver diseases, and 11.2 (95% CI 8.1-15.3) for liver cancers. Particularly elevated SMRs emerged among PWA aged 15-49 years and those infected by injecting drug use. CONCLUSIONS: The high excess liver-related mortality observed among PWA warrants preventive actions to limit the burden of viral hepatitis coinfections, alcohol abuse, and metabolic disorders, especially among younger PWA and injecting drug users.

Análisis de la mortalidad por tuberculosis, en Costa Rica / Tuberculosis Mortality Analysis in Costa Rica

Resumen Justificación: La mortalidad por tuberculosis reúne características para ser estudiada con un enfoque de causa básica y de causa múltiple, debido a que compite frecuentemente con otras patologías como causa básica de muerte. Los objetivos de este estudio son caracterizar las defunciones por tuberculosis en ambas formas, utilizando las variables: tiempo, lugar y persona; cuantificar la concordancia entre las defunciones por tuberculosis registradas por el Programa Institucional, y el certificado de defunción, e identificar la contribución de esta enfermedad en la mortalidad con un enfoque multicausal, en Costa Rica, durante el periodo 2016-2019. Materiales y métodos: Estudio descriptivo. La población de estudio correspondió a todas las defunciones por tuberculosis y con tuberculosis registradas en el libro de registro del programa de de la Caja Costarricense de Seguro Social, ocurridas en 2016 - 2019. Por medio del expediente de salud se depuraron las defunciones registradas y se categorizaron de acuerdo con la Clasificación Internacional de Enfermedades 10 en defunciones por tuberculosis (A15 al A19), tuberculosis / virus de inmunodeficiencia humana (A15 al A19-B24 ), tuberculosis / diabetes mellitus (A15 al A19-E10,E11), tuberculosis / cáncer (A15 al A19-C34,22,18) y tuberculosis / otras (A15 al A19- J44,J45). En el certificado de defunción se revisó la secuencia informada de las causas de muerte y la causa contribuyente, para identificar la tuberculosis como causa básica o múltiple. Se agruparon los resultados por edad y se calculó: porcentajes, tasas, proporción de concordancia observada, proporción de concordancia esperada y el índice de Kappa (va de 0 a 1, y el 1 representa la máxima concordancia). Resultados: Durante el periodo de estudio (4 años), se registró un total de 113 defunciones, lo que corresponde a una tasa de mortalidad de 0,57 / 100 000 hab.; de éstas, el 73% (83) correspondió a personas del sexo masculino y el 27 %, al sexo femenino. El mayor número de defunciones ocurrió principalmente en el grupo de mayores de 65 años, tanto para los hombres como para las mujeres. La proporción de concordancia observada correspondió a un 0,77 %, y la proporción de concordancia esperada a un 26%. Al ser la proporción de concordancia observada mayor que la esperada, y con un índice de Kappa de 0,70, concluimos que la concordancia existente es considerable y se atribuye más a ser causal que al azar. El análisis de mortalidad de tubercolosis por causa múltiple no mostró cambios en la tasa de mortalidad, tomando en cuenta este evento como causa básica de defunción o como causa múltiple. Conclusiones: Con base en los resultados del estudio, se evidencia que existe una concordancia considerable entre el registro de las defunciones por tuberculosis anotadas en el libro del programa institucional y el certificado de defunción.

Abstract Background: Tuberculosis mortality has the characteristics to be studied as a basic and multiple cause of death, because it can be compared with other pathologies as a basic cause of death. The goals of this study are to characterize deaths from tuberculosis including basic and multiple cause of death using time, place and person as variables, to measure the concordance of deaths from tuberculosis recorded in the Institutional Program Record Book and death certificate; and to identify the contribution of this disease in mortality with a multicausal approach, in Costa Rica during the period 2016-2019. Methods: Descriptive study. The study population corresponded to all deaths from tuberculosis and tuberculosis recorded in the Program Registration Book of the Social Security Costa Rican entity, that occurred in the period between 2016 and 2019. Using the health files, the deaths registered in the Program Registration Book were purified and categorized according to International Classification of Diseases 10 in deaths due to tuberculosis (A15 through A19), tuberculosis/human immunodeficiency virus (A15 through A19-B24), tuberculosis/diabetes mellitus (A15 through A19-E10, E11), tuberculosis/cancer (A15 through A19 -C34,22,18) and tuberculosis/others (A15 through A19-J44, J45). In the death certificate, the reported sequence of the causes of death and the contributing cause to identify tuberculosis as a basic or multiple cause were reviewed. Percentages, rates, observed concordance ratio, expected concordance ratio and Kappa index were calculated (value from 0 to 1, 1 representing the maximum concordance). Results: During the study period (4 years), a total of 113 deaths were registered, with a mortality rate of 0.57/100,000 inhabitants. Of these, 73% (83) corresponded to the male sex and 27% (30) to the female sex. The highest number of deaths occurred mainly in the group of people over 65 years, for both men and women. The observed concordance ratio corresponded to 0.77% and the expected concordance ratio to 26%. Since the observed concordance ratio is greater than expected concordance ratio and when obtaining a Kappa index of 0.70, it is concluded that the existing concordance is attributed more causally than by chance. The multiple cause tuberculosis mortality analysis did not show changes in the mortality rate, taking this event into account only as a basic cause of death or as a multiple cause. Conclusions: The study made it possible to show that there is a considerable concordance between the register of deaths from tuberculosis recorded in the register of the Institutional Program and the death certificate.

Educational inequalities in fracture-related mortality using multiple cause of death data in the Skåne region, Sweden.

Aim: To assess the absolute and relative educational inequalities in mortality from hip and non-hip fractures in Skåne region, Sweden. Methods: We conducted a population-based open cohort study. People aged 30-99 years, resident in the region during 1998-2013 (n = 999, 148) were followed until death, their 100th birthday, relocation outside Skåne, or the end of 2014. We obtained individual-level data from the Statistics Sweden and the Swedish National Board of Health and Welfare's Cause of Death Register. Death certificates coded with any fracture diagnosis were defined as fracture-related deaths. Educational inequalities were assessed by slope and relative indices of inequality (SII and RII). Cox regression and additive hazard models were used to estimates these indices. Results: During a mean follow-up of 12.2 years, there were 5,121 fracture-related deaths, of which 3,110 were associated with hip fracture. Age-standardized, hip fracture-related mortality rates per 100,000 person-years were 31, 95% confidence interval (CI) (30, 32) and 23 (20, 26) in people with low and high levels of education, respectively (rate ratio 1.4, 95% CI (1.2, 1.5)). Corresponding mortality rates for non-hip-fracture related deaths were 20 (18, 21) and 16 (14, 19) (rate ratio 1.2, 95% CI (1.0, 1.4)). SII and RII revealed educational inequalities in hip fracture-related mortality in favour of highly educated people. For non hip fracture-related mortality, there were statistically significant educational inequalities in people aged <70 years. Conclusions: We found higher fracture-related mortality with lower education suggesting preventative and therapeutic interventions for fractures should pay special attention to people with low-level education.

Educational inequalities in all-cause and cause-specific mortality among people with gout: a register-based matched cohort study in southern Sweden.

BACKGROUND: Gout is the most common inflammatory arthritis with a rising prevalence around the globe. While educational inequalities in incidence and prevalence of gout have been reported, no previous study investigated educational inequality in mortality among people with gout. The aim of this study was to assess absolute and relative educational inequalities in all-cause and cause-specific mortality among people with gout in comparison with an age- and sex-matched cohort free of gout in southern Sweden. METHODS: We identified all residents aged ≥30 years of Skåne region with doctor-diagnosed gout (ICD-10 code M10, n = 24,877) during 1998-2013 and up to 4 randomly selected age- and sex-matched comparators free of gout (reference cohort, n = 99,504). These were followed until death, emigration, or end of 2014. We used additive hazards models and Cox regression adjusted for age, sex, marital status, and country of birth to estimate slope and relative indices of inequality (SII/RII). Three cause-of-death attribution approaches were considered for RII estimation: "underlying cause", "any mention", and "weighted multiple-cause". RESULTS: Gout patients with the lowest education had 1547 (95% CI: 1001, 2092) more deaths per 100,000 person-years compared with those with the highest education. These absolute inequalities were larger than in the reference population (1255, 95% CI: 1038, 1472). While the contribution of cardiovascular (cancer) mortality to these absolute inequalities was greater (smaller) in men with gout than those without, the opposite was seen among women. Relative inequality in all-cause mortality was smaller in gout (RII 1.29 [1.18, 1.41]) than in the reference population (1.46 [1.38, 1.53]). The weighted multiple-cause approach generally led to larger RIIs than the underlying cause approach. CONCLUSIONS: Our register-based matched cohort study showed that low level of education was associated with increased mortality among gout patients. Although the magnitude of relative inequality was smaller in people with gout compared with those without, the absolute inequalities were greater reflecting a major mortality burden among those with lower education.

Educational inequalities in mortality associated with rheumatoid arthritis and other musculoskeletal disorders in Sweden.

BACKGROUND: Musculoskeletal (MSK) disorders are less likely to be reported as an underlying cause of death (UCD) and since cause of death studies are generally limited to the UCD, little is known about socioeconomic inequalities in MSK disorders as cause of death in the general population. Using multiple-cause-of-death data, we aimed to quantify and compare educational inequalities in musculoskeletal (MSK) disorders- with non-MSK disorders-related mortality. METHODS: All residents aged 30-99 years in the Skåne region, Sweden, during 1998-2013 (n = 999,148) were followed until their 100th birthday, death, relocation outside Skåne, or end of 2014. We identified any mention of rheumatoid arthritis (RA) or other MSK disorders on death certificates using multiple-cause-of-death data. We retrieved and linked individual-level data from Statistics Sweden on highest level of education. We used Cox regression and additive hazards models with age as time-scale adjusted for sex, marital status, and country of birth to calculate slope and relative indices of inequality (SII/RII). RESULTS: During a mean follow-up of 12.2 years, there were 1407 (0.8% of all deaths) and 3725 (2.1% of all deaths) death certificates with mention of RA and other MSK disorders, respectively, and 171,798 death certificates without any mention of a MSK disorder. Age-standardized RA mortality rate was 2.2 (95% confidence interval [CI]: 2.0-2.8) times greater in people with 0-9 years of education compared with those with > 12 years of education. Corresponding figure for other MSK disorders was 1.5 (95% CI: 1.4-1.6). Both RIIs and SIIs revealed statistically significant educational inequalities in RA/other MSK disorders mortality favouring high-educated people. The RIIs of MSK disorders-related deaths were generally greater than non-MSK disorders-related deaths. CONCLUSION: We found substantial educational inequality in mortality from MSK disorders. Further research is needed to investigate underlying pathways driving these inequalities.

Fracture-related mortality in southern Sweden: A multiple cause of death analysis, 1998-2014.

PURPOSE: To assess fracture-related mortality among adults (aged ≥20years) in southern Sweden using multiple causes of death approach. METHODS: All death certificates (n=201 488) in adults recorded in the region of Skåne from 1998 to 2014 were examined. We identified fracture-related deaths and computed mortality rates by sex, age group, and fracture site. Temporal trends were evaluated using joinpoint regression and associated causes were identified by age- and sex-adjusted observed/expected ratios. RESULTS: Fractures were mentioned on 6 226 (3.1%) death certificates, with majority of these occurred among women (60%) and those aged≥80years (77%). While hip was the most common site overall (61% of all fracture-related deaths), skull was the most common site in people <60years (60% of all fracture-related deaths). Proportion of death certificates mentioning fracture was stable in women but increased by 0.4% (95% CI: 0.1 to 0.6) in men between 1998-2002 and 2010-2014. The mean age at death was higher in death certificates mentioning fracture than those without and this gap widened over time. The mean age-standardized fracture-related mortality rate was 18.8 (14.0) per 100 000 person-year in men (women) and declined by 1.5% (1.3%) per year during 1998-2014. Injuries (84.6%) and cardiovascular disorders (64.6%) were the most common comorbidities on death certificates mentioning fracture. CONCLUSIONS: Fracture is a contributing cause of death in more than 3% of all deaths in southern Sweden with hip in lead among older and skull fracture among younger people. There was a slight increase in proportion of deaths associated with fracture in men but not women during the study period.

Educational inequalities in falls mortality among older adults: population-based multiple cause of death data from Sweden.

BACKGROUND: Falls are the leading cause of fatal injuries among elderly adults. While socioeconomic status including education is a well-documented predictor of many individual health outcomes including mortality, little is known about socioeconomic inequalities in falls mortality among adults. This study aimed to assess educational inequalities in falls mortality among older adults in Sweden using multiple cause of death data. METHODS: All residents aged 50‒75 years in the Skåne region, Sweden, during 1998‒2013 (n=566 478) were followed until death, relocation outside Skåne or end of 2014. We identified any mention of falls on death certificates (n=1047). We defined three levels of education. We used an additive hazards model and Cox regression with age as time scale adjusted for marital status and country of birth to calculate slope and relative indices of inequality (SII/RII). We also computed the population attributable fraction of lower educational attainment. Analyses were performed separately for men and women. RESULTS: Both SII and RII revealed statistically significant educational inequalities in falls mortality among men in favour of high educated (SII (95% CI): 15.5 (9.8 to 21.3) per 100 000 person-years; RII: 2.19 (1.60 to 3.00)) but not among women. Among men, 34% (95% CI 19 to 46) of falls deaths were attributable to lower education. CONCLUSIONS: There was an inverse association between education and deaths from falls among men but not women. The results suggest that individual's education should be considered in falls reduction interventions.

Causas múltiplas de mortalidade materna relacionada ao aborto no Estado de Minas Gerais, Brasil, 2000-2011 / Multiple causes of maternal mortality related to abortion in Minas Gerais State, Brazil, 2000-2011 / Causas múltiples de mortalidad materna relacionada con el aborto, en el Estado de Minas Gerais, Brasil, 2000-2011

Resumo: Este estudo objetivou analisar a evolução da mortalidade materna por aborto em Minas Gerais, Brasil, no período de 2000 a 2011, sob o enfoque das causas múltiplas de morte. Estudou-se as características sociodemográficas das mulheres, ano, local e causas básica e associada de óbito. Foi calculada a razão de morte materna (RMM) geral e específica por aborto em cada ano e o coeficiente de correlação de Spearman (p < 0,05), para avaliar a evolução das razões no período. Foram registrados 183 óbitos por aborto, 15% dos óbitos maternos, e a RMM por aborto manteve-se estável. A razão causa múltipla e causa básica de óbito por aborto foi de 1,38. O uso do método de análise de causas múltiplas mostrou-se eficaz para dar maior visibilidade ao aborto. Os problemas oriundos da ilegalidade da prática de abortos favorecem o aparecimento de causas que mascaram mortes maternas e a sua subnotificação. Assim, ações intersetoriais são necessárias para a definição de estratégias, a fim de reduzir as desigualdades sociais e melhorar a qualidade dos serviços de atenção à mulher.

This study aimed to analyze trends in maternal mortality from abortion in Minas Gerais State, Brazil, from 2000 to 2011, addressing multiple causes of death. The analysis focused on women's social and demographic characteristics, year, location, and underlying and associated causes of death. Maternal mortality ratio (MMR) and abortion-specific ratio were calculated for each year, as well as Spearman's correlation coefficient (p < 0.05), to assess the trend in ratios during the study period. One hundred and eighty-three deaths from abortion were recorded, accounting for 15% of maternal deaths, and MMR remained stable. The ratio between multiple causes and underlying cause of death from abortion was 1.38. Use of the multiple-causes method proved effective for lending greater visibility to abortion. Problems deriving from the illegality of abortion in Brazil favor the appearance of causes that mask maternal deaths, in addition to their underreporting. Inter-sector actions are thus necessary to define strategies for reducing social inequalities and improving the quality of services for women.

Resumen: Este estudio tuvo por objetivo analizar la evolución de la mortalidad materna por aborto en Minas Gerais, Brasil, durante el período de 2000 a 2011, desde el enfoque de las causas múltiples de muerte. Se estudiaron las características sociodemográficas de las mujeres, año, lugar y causas básicas y asociadas de óbito. Se calculó la razón de muerte materna (RMM) general y específica por aborto durante cada año y el coeficiente de correlación de Spearman (p < 0,05), para evaluar la evolución de las razones durante el período. Se registraron 183 óbitos por aborto, un 15% de los óbitos maternos, y la RMM por aborto se mantuvo estable. La razón causa múltiple y causa básica de óbito por aborto fue de 1,38. El uso del método de análisis de causas múltiples se mostró eficaz para dar mayor visibilidad al aborto. Los problemas provenientes de la ilegalidad de la práctica de abortos favorecen la aparición de causas que enmascaran muertes maternas y su subnotificación. Por ello, se necesitan acciones intersectoriales para la definición de estrategias, con el fin de reducir las desigualdades sociales y mejorar la calidad de los servicios de atención a la mujer.

El síndrome NSLQT / The Syndrome of No One Knows What the Patient Has

Se hace una serie de consideraciones a partir de la denominación operativa de síndrome NSLQT: nadie sabe lo que tiene, frase introducida de manera ingeniosa en el Hospital General Universitario de Cienfuegos, para calificar a los pacientes en los que, a pesar de innumerables esfuerzos de todo tipo: clínicos, de indicación de exámenes complementarios, discusiones y rediscusiones diagnósticas, consultas e interconsultas a los más disímiles especialistas, no se puede precisar con claridad el padecimiento de base del enfermo. Esta es una situación estresante para los enfermos, los familiares y el personal a cargo de la atención, con significación no solo en el ámbito asistencial, sino también administrativo, social, ético y posiblemente legal.

This paper presents a series of considerations on the syndrome known as no one knows what the patient has, a phrase ingeniously coined at the University General Hospital of Cienfuegos to refer to those patients whose underlying condition cannot be clearly established despite countless efforts of all sorts: application of clinical methods, investigations, continuous diagnostic discussions, and consultations with the most diverse specialists. This represents a stressful situation for patients, relatives, and medical staff, with a significant impact not only on the health care setting, but also on administrative, social, ethical, and possibly legal spheres.

Insuficiência renal crônica e as causas múltiplas de morte: uma análise descritiva para o Brasil, 2000 a 2004 / Chronic kidney failure and multiple causes of death: a descriptive analysis for Brazil, 2000-2004

INTRODUÇÃO: A doença renal crônica é uma enfermidade que atinge um número cada vez maior de indivíduos no Brasil e no mundo. OBJETIVOS: Analisar indicadores de causas múltiplas de morte para os pacientes em terapia renal substitutiva (TRS) no Brasil que faleceram entre 2000 e 2004. MÉTODOS: Os indicadores foram calculados com base no número de diagnósticos informados nas declarações de óbito e nas menções das causas de morte. O número médio de diagnóstico por declaração de óbito foi analisado por idade, sexo, modalidade de tratamento e região de residência do paciente. RESULTADOS: O estudo da mortalidade por doença renal crônica por meio apenas da causa básica implicaria perda de informações. Quantitativamente, o número médio de diagnósticos por declaração de óbito da população analisada foi 2,9. Qualitativamente, a análise das menções das causas de morte nas declarações de óbito revelou que a morbimortalidade dessa população é conformada por diversas doenças que frequentemente não aparecem como causa básica de óbito, sendo mandatória a utilização do modelo de causas múltiplas. CONCLUSÕES: A análise descritiva é a maneira mais simples e direta de se analisar a mortalidade sob o enfoque de múltiplas causas. .

INTRODUCTION: Chronic kidney disease is an illness that affects a growing number of individuals in Brazil and worldwide. OBJECTIVES: To analyze indicators of multiple causes of death for patients in renal replacement therapy in Brazil who died between 2000 and 2004. METHODS: The indicators were calculated based on the number of diagnoses reported on death certificates and on the information on causes of death. The average number of diagnosis per certificate was analyzed by age, sex, treatment mode, and region of residence. RESULTS: Studying the mortality from chronic kidney disease by means of the underlying would lead to information loss. Analysis showed that the average number of diagnoses per death certificate was 2.9 and also that the mortality of this population group is composed of a number of illnesses that often do not appear as underlying cause of death. Multiple causes of death model enhance the possibilities of analysis. CONCLUSIONS: The descriptive analysis is the simplest and most direct way to analyze the mortality from this perspective. .

Aplicabilidad del análisis por causa múltiple de muerte para el cáncer cervicouterino: la experiencia en México / Applicability of the analysis by multiple cause of death by cervical cancer: the experience in Mexico

Objecto. Explora-se a aplicabilidad da análise por causa múltipla de morte para o estudo do cancro cervicouterino. Métodos. Desenho de mortalidade proporcional para analisar todas as causas consignadas na totalidade dos certificados de morte por cancro cervicouterino de mulheres maiores de 18 anos do Estado de México (367), e 515 certificados de mulheres falecida por outras causas. Resultados. Encontrou-se uma razão de causa básica/múltipla de 2.9 nos certificados de morte, isto é pela cada causa básica encontraram-se 2.9 As mulheres falecidas por cancro cervicouterino morrem cinco anos dantes que as que morrem por outras causas (p<0.05). Ao ajustar as análise por causa múltipla para cancro cervicouterino por idade, escolaridad, estado civil, e direito habiencia, destaca a participação dos tumores malignos de lugares mau definidos como causas contribuintes e condicionantes [OR=14.24 (1.67-121.0) e OR=18.98 (2.28-157.56, respectivamente]; seguido pela diabetes mellitus também como contribuintes e sócias [OR=1.82 (1.02-3.27) e OR=7.78(1.46-41.37)] e a hipertensión arterial sistémica como causa sócia [OR = 3.0 (1.39-6.47)]. Conclusões. Causa múltipla é uma análise adequada para observar as doenças que intervêm, contribuem, condicionan e se associam ao cancro cervicouterino no momento da morte.

Objective. The study explores the applicability of the multiple-cause-of-death analysis for cervical-uterine cancer. Methods. A proportional mortality hazard design and the analysis of all causes of death due to cervical-uterine cancer from 367 death certificates of women older than 18 years of age from the State of Mexico, and 515 age and year adjusted sample of death certificates of women from the same region who died from other causes. Results. A basic multiple cause of death of 2.9 was observed in the death certificates, i.e., for every basic cause there were 2.9 multiple causes. When adjusting the multiple-causes-of-death analysis for cervical-uterine cancer by age, education, marital and insurability status, the most contributing and associated causes of death were malignant tumors from unspecified sites [OR=18.98 (2.28-157.56) and OR=14.25 (1.67-121.0)] respectively; Diabetes Mellitus as a contributing [OR=1.82 (1.02-3.27) and associated cause [OR=7.78 (1.46-41.37], and systemic arterial hypertension as an associated cause [OR=3.00 (1.40-6.47)]. Conclusions. The multiple-cause-of-death analysis is an adequate to observe the diseases that contribute condition and are associated to the cervical-uterine cancer.

Mortalidade de idosos com desnutrição em Belo Horizonte, Minas Gerais, Brasil: uma análise multidimensional sob o enfoque de causas múltiplas de morte / Mortality of malnourished elderly in Belo Horizonte, Minas Gerais State, Brazil: a multidimensional analysis focusing on multiple causes of death

O objetivo deste estudo foi identificar perfis de mortalidade em idosos com desnutrição, a partir de associações entre causas múltiplas de morte e outras variáveis da Declaração de Óbito. Foram estudadas as mortes de residentes de Belo Horizonte, Minas Gerais, Brasil, com 60 anos e mais, que tinham a desnutrição como uma das causas mencionadas. Utilizaram-se os dados do Sistema de Informações sobre Mortalidade. Para estudo das associações, foi empregada a análise multidimensional pela técnica de análise fatorial de correspondência múltipla. A pesquisa mostrou sobremortalidade feminina, maior concentração de mortes na raça branca, em viúvos e em idosos com baixa escolaridade. Foram estabelecidos dez perfis de mortalidade e a desnutrição foi evidenciada cerca de cinco vezes mais pelo enfoque das causas múltiplas. Confirmou-se a importância das causas múltiplas para evidenciar causas de morte não detectadas pelo enfoque de causa básica e a adequação da técnica de análise de correspondência múltipla para identificar as associações de causas e demais variáveis da Declaração de Óbito.

This study aimed to identify the mortality profiles of elderly individuals with malnutrition, based on associations between multiple causes of death and other variables recorded on the death certificate. We studied the deaths of elderly (> 60 years) living in Belo Horizonte, Minas Gerais State, Brazil, with malnutrition recorded as one of the causes. Data were used from the mortality information system. Multiple correspondence analysis was used to investigate these associations. The study showed excess mortality among women, whites, widowers, and individuals with low schooling. Ten mortality profiles were studied, and malnutrition was five times more frequent according to the multiple-causes technique. The results showed both the importance of multiple causes of death not detected by focusing on the underlying cause and the adequacy of multiple correspondence analysis for identifying the associations between causes and other variables listed on the death certificate.
