RESUMO

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.

RESUMO

Background & objectives: During the COVID-19 pandemic, the death rate was reportedly 5-8 fold lower in India which is densely populated as compared to less populated western countries. The aim of this study was to investigate whether dietary habits were associated with the variations in COVID-19 severity and deaths between western and Indian population at the nutrigenomics level. Methods: In this study nutrigenomics approach was applied. Blood transcriptome of severe COVID-19 patients from three western countries (showing high fatality) and two datasets from Indian patients were used. Gene set enrichment analyses were performed for pathways, metabolites, nutrients, etc., and compared for western and Indian samples to identify the food- and nutrient-related factors, which may be associated with COVID-19 severity. Data on the daily consumption of twelve key food components across four countries were collected and a correlation between nutrigenomics analyses and per capita daily dietary intake was investigated. Results: Distinct dietary habits of Indians were observed, which may be associated with low death rate from COVID-19. Increased consumption of red meat, dairy products and processed foods by western populations may increase the severity and death rate by activating cytokine storm-related pathways, intussusceptive angiogenesis, hypercapnia and enhancing blood glucose levels due to high contents of sphingolipids, palmitic acid and byproducts such as CO2 and lipopolysaccharide (LPS). Palmitic acid also induces ACE2 expression and increases the infection rate. Coffee and alcohol that are highly consumed in western countries may increase the severity and death rates from COVID-19 by deregulating blood iron, zinc and triglyceride levels. The components of Indian diets maintain high iron and zinc concentrations in blood and rich fibre in their foods may prevent CO2 and LPS-mediated COVID-19 severity. Regular consumption of tea by Indians maintains high high-density lipoprotein (HDL) and low triglyceride in blood as catechins in tea act as natural atorvastatin. Importantly, regular consumption of turmeric in daily food by Indians maintains strong immunity and curcumin in turmeric may prevent pathways and mechanisms associated with SARS-CoV-2 infection and COVID-19 severity and lowered the death rate. Interpretation & conclusions: Our results suggest that Indian food components suppress cytokine storm and various other severity related pathways of COVID-19 and may have a role in lowering severity and death rates from COVID-19 in India as compared to western populations. However, large multi-centered case-control studies are required to support our current findings.

RESUMO

OBJECTIVE: The countries of the Community of Latin American and Caribbean States (CELAC, by its initials in Spanish) have been some of the most affected by COVID-19. This paper analyzes whether, in the 33 CELAC countries, population density, together with other economic variables, such as gross domestic product (GDP) at purchasing power parity (PPP) values or the Human Development Index (HDI), were significantly associated with the coronavirus mortality rate. METHODS: A correlation analysis and an ordinary least squares regression model were used to analyze the effects of different variables on the COVID-19 mortality rate. RESULTS: The results showed that countries with higher numbers of inhabitants per square kilometer had lower death rates. Gross domestic product was not associated with the number of deaths, while the HDI had a positive impact on that number. CONCLUSION: Countries with high population density are not more vulnerable to COVID-19, as population density allows for economic development and better-designed institutions.

RESUMO

Colorado issued a month long statewide lockdown on March 26, 2020, during the initial surge of the COVID-19 pandemic. The impact of this mandate on non-COVID-19 ICU admission rates and outcomes is unclear. DESIGN: We performed a retrospective analysis of all medical ICU admissions in the University of Colorado Health System in four predefined periods: 1) prepandemic (2 mo prior to lockdown period 1); 2) mandated lockdown from March 26 to April 26, 2020 (period 2); 3) between surges (period 3); and 4) nonmandated lockdown surge (between November 1, 2020, and March 31, 2021, period 4). SETTING: Nonsurgical ICU admissions at the University of Colorado Health Systems, including 10 hospitals throughout Colorado. SUBJECTS: All ICU admissions in four predefined time periods. MEASUREMENTS AND MAIN RESULTS: We included 13,787 patients who were admitted during the four study periods. The 28-day mortality rates for non-COVID-19 ICU admissions following index ICU admission were 13.6%, 18.0%, 13.5%, and 16.0% across periods 1-4, respectively. However, the increased odds in non-COVID-19 ICU mortality during the mandated lockdown period relative to prepandemic 1 (odds ratio [OR], 1.39; 95% CI, 1.11-1.72; p = 0.0.04) was attenuated and nonsignificant after adjustment for demographics, comorbidities, diagnosis flags, and severity (OR, 1.15; 95% CI, 0.89-1.48; p = 0.27). Similar results were found in time-to-event analyses. The most common diagnosis in each time period was acute respiratory failure (ARF), and we found it to have increased during lockdown (p < 0.001), whereas sepsis admissions increased during and decreased after lockdown (p = 0.004). Admissions for alcohol withdrawal syndrome (AWS) increased during lockdown and 6 months afterwards (p = 0.005). CONCLUSIONS: For non-COVID-19-related ICU admissions, mortality rate was similar before, during, and after Colorado's month long lockdown after confounder adjustment, including typical ICU admission flags. Primary admission diagnoses shifted throughout the predefined study periods with more admissions for severe critical diagnoses (i.e., ARF, sepsis, AWS) occurring during the mandated lockdown and nonmandated lockdown periods compared with the prepandemic and between surge period. This would suggest that the perceived increase in mortality during the lockdown for non-COVID-19 ICU admissions may be related to a shift inpatient demographics.

RESUMO

Abstract This study evaluated the economic impact of gastrointestinal nematode (GIN) infection in Morada Nova lambs under different parasite chemical control conditions. For this, 246 lambs, in the rainy and dry season, were randomized into groups according to their anthelmintic treatment with levamisole: control (CT: no treatment); routine treatment (RT: treated every 42 days); and targeted selective treatment (TST: treated according to the average daily weight gain, DWG). From 63 days of age (D63) to D210, the lambs were weighed and monitored for GIN infection parameters. Spending on anthelmintics in the production system was 1.3% of the total economic result. The economic result per animal (R$ 5.00 = US$ 1.00) was higher in the RT group, amounting to US$ 6.60 in the rainy and US$ 5.69 in the dry season, due to higher DWG. Thus, RT presented economic results 14.4% and 10.9% higher than CT, and 7.2% and 1.9% higher than TST, in the rainy and dry season, respectively. However, fast development of resistance made RT unfeasible. Here, the economic impact of GIN infection on a national scale is discussed, demonstrating its importance and the impossibility of profitable and sustainable sheep production without adequate control.


Resumo Este estudo avaliou o impacto econômico da infecção por nematoides gastrintestinais (NGI), em cordeiros Morada Nova, sob diferentes condições de controle químico dos parasitas. Para isso, 246 cordeiros, na estação chuvosa e seca, foram randomizados em grupos de acordo com o tratamento com levamisol: controle (TC: sem tratamento); tratamento rotineiro (TR: tratado a cada 42 dias); e tratamento seletivo direcionado (TST: tratado de acordo com o ganho de peso médio diário, GMD). Dos 63 dias de idade (D63) ao D210, os cordeiros foram pesados ​​e monitorados quanto aos parâmetros de infecção por NGI. O gasto com anti-helmínticos no sistema produtivo foi de 1,3% do resultado econômico total. O resultado econômico por animal (R$ 5,00 = US$ 1,00) foi maior no grupo RT, totalizando US$ 6,60 na estação chuvosa e US$ 5,69 na seca, devido ao maior GMD. Assim, o RT apresentou resultados econômicos 14,4% e 10,9% superiores ao TC, e 7,2% e 1,9% superiores ao TST, no período chuvoso e seco, respectivamente. Entretanto o rápido desenvolvimento de resistência inviabiliza o TR. O impacto econômico da infecção por NGI em escala nacional são aqui discutidos, demonstrando sua importância e a impossibilidade de uma ovinocultura lucrativa e sustentável sem o controle adequado.

RESUMO

Introduction: Identification of predictors for successful extubation in an Intensive Care Unity and use of Brain Natriuretic Peptides (BNP) in predicting mechanical ventilation weaning and extubation outcome. Aims: Evaluation of the effect of variables such as patient ́s age, severity score, use of sedation, use of vasoactive drugs, hydric balance, blood gas data, days under mechanical ventilation, the occurrence of adverse events and plasma BNP levels on the success of extubation.Method: A prospective cohort study of adult patients admitted to a 12- bed-general ICU, from April 1st 2016 to August 10th 2017, under mechanical ventilation for > 24 h, accompanied until discharge or death. Clinical variables were analyzed and BNP was assessed before initiation of Spontaneous Breathing Trial (SBT) and then again before extubation. Statistical Analysis: a descriptive and comparative data analysis, univariate and logistic regression analysis for verification of variables independently related to successful extubation (p < 0.05).Results: Study of 105 patients, mean age of 53.9 ± 19.8 years, 81% of success in extubation; the overall mortal-ity rate of 11.4%; variables associated to successful extubation: age, APACHE II, SAPS II, days of hospitalization before ICU admittance, days under mechanical ventilation, days of stay in ICU and occurrence of nosocomial infec-tion (p < 0.05); BNP levels were lower in patients with successful extubation although not statistically significant; multivariate analysis showed that patient's age and days of hospitalization before ICU admittance were each in-dependently linked to extubation failure; APACHE II score and days of hospitalization before ICU admittance were each independently associated to risk of death.Conclusion: Despite being older and with higher severity scores, patients had a higher success rate in extubation than found in similar studies. However, the mortality rate in cases of failed extubation was higher. Data obtained was in agreement to studies that suggested that patient ́s age, severity score, days of hospitalization before ICU admittance, days of stay in ICU, days under MV and infection occurrence were all variables associated as much extubation failure as to risk of death. A direct association between BNP levels and successful extubation and the usefulness of assessing BNP in the conduction of WMV was not confirmed. (AU)


Introdução: Identificação de fatores preditivos do sucesso da extubação em Unidade de Terapia Intensiva e uso do Peptídeo Natriurético Cerebral (BNP) como preditor do sucesso do desmame da ventilação mecânica e extubação.Objetivo: Avaliação do efeito de variáveis como idade, escores de gravidade, uso de sedação, uso de drogas va-soativas, balanço hídrico, gasometria, dias sob ventilação mecânica, ocorrência de eventos adversos e níveis plas-máticos de BNP no sucesso da extubação .Método: Estudo de coorte prospectivo de pacientes adultos internados em UTI geral com 12 leitos, de 1º de abril de 2016 a 10 de agosto de 2017, sob ventilação mecânica (VM) por > 24 horas, acompanhados até a alta ou óbito. Variáveis clínicas foram analisadas e o BNP dosado antes do início do Teste de Respiração Espontânea (TRE) e, novamente, antes da extubação. Análise estatística: análise descritiva e comparativa dos dados, análise univariada e regressão logística para verificação de variáveis independentemente relacionadas ao sucesso da extubação (p <0,05).Resultados: Avaliados 105 pacientes, idade média 53,9 ± 19,8 anos, sucesso na extubação de 81%; taxa de mortalidade geral de 11,4%; variáveis associadas ao sucesso da extubação: idade, APACHE II, SAPS II, dias de internação antes da admissão na UTI, dias em ventilação mecânica, dias de permanência na UTI e ocorrência de infecção hospitalar (p <0,05); os níveis de BNP foram mais baixos em pacientes com sucesso da extubação, embora não estatisticamente significativos; a análise multivariada mostrou que as variáveis, idade e dias de internação, antes da admissão na UTI, estavam, independentemente, ligadas ao fracasso da extubação; as variáveis APACHE II e dias de internação antes da admissão na UTI estavam, independentemente, associados ao risco de morte.Conclusão: Apesar de mais velhos e com escores de gravidade mais elevados, nossos pacientes apresentaram maior taxa de sucesso na extubação quando comparados a estudos semelhantes. No entanto, a taxa de mortalidade em casos de falha da extubação foi maior. Os dados obtidos estão de acordo com estudos que sugerem que variá-veis como idade, escores de gravidade, dias de internação antes da admissão na UTI, dias de permanência na UTI, dias em VM e ocorrência de infecção estão associadas tanto ao fracasso de extubação quanto ao risco de morte. Não foi possível confirmar a associação direta entre os níveis plasmáticos de BNP e o sucesso da extubação, assim como sua utilidade na condução do desmame da ventilação mecânica. (AU)

RESUMO

Coronavirus disease 2019 (COVID-19) has placed stress on all National Health Systems (NHSs) worldwide. Recent studies on the disease have evaluated different variables, namely, quarantine models, mitigation efforts, damage to mental health, mortality of the population with chronic diseases, diagnosis, use of masks and social distancing, and mortality based on age. This study focused on the four NHSs recognized by the WHO. These systems are as follows: (1) The Beveridge model, (2) the Bismarck model, (3) the National Health Insurance (NHI) model, and (4) the "Out-of-Pocket" model. The study analyzes the response of the health systems to the pandemic by comparing the time in days required to double the number of disease-related deaths. The statistical analysis was limited to 56 countries representing 70% of the global population. Each country was grouped into the health system defined by the WHO. The study compared the median death toll DT, between health systems using Mood's median test method. The results show high variability of the temporal trends in each group; none of the health systems for the three analyzed periods maintain stable interquartile ranges (IQRs). Nevertheless, the results obtained show similar medians between the study groups. The COVID-19 pandemic saturates health systems regardless of their management structures, and the result measured with the time for doubling death rate variable is similar among the four NHSs.

RESUMO

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has been a worldwide challenge, and efforts to "flatten the curve," including restrictions imposed by policymakers and medical societies, have forced a reduction in the number of procedures performed in the Brazilian Health Care System. The aim of this study is to evaluate the outcomes of coronary artery bypass graft (CABG) from 2008 to 2020 in the SUS and to assess the impacts of the COVID-19 pandemic in the number of procedures and death rate of CABG performed in 2020 through the database DATASUS. METHODS: This study is based on publicly available material obtained from DATASUS, the Brazilian Ministry of Health's data processing system, on numbers of surgical procedures and death rates. Only isolated CABG procedures were included in our study. We used the TabNet software from the DATASUS website to generate reports. RESULTS: We identified 281,760 CABG procedures performed from January 2008 to December 2020. The average number of procedures until the end of 2019 was of 22,104. During 2020 there was a 25% reduction CABG procedures, to 16,501. There was an increase in the national death rate caused by a statistical significant increase in death rates in Brazil's Southeast and Central-west regions. CONCLUSION: The COVID-19 pandemic remains a global challenge for Brazil's health care system. During the year of 2020 there was a reduction in access to CABG related to an increase in the number of COVID-19 cases. There was also an increase in the national CABG death rate.

RESUMO

BACKGROUND: Eosinophil counts increase during chronic obstructive pulmonary disease (COPD) exacerbation and influence the response to different agents (such as inhaled and systemic corticosteroids), as well as increase the production of other inflammatory cytokines. However, few studies have evaluated the association between peripheral blood eosinophils with mortality rate. OBJECTIVE: To evaluate the association between peripheral blood eosinophils and mortality rate in COPD patients over a nine-year period. STUDY DESIGN AND METHODS: This cohort included 133 COPD patients assessed at baseline by spirometry, pulse oximetry (SpO2), complete blood count, body composition, dyspnea intensity [Modified Medical Research Council (mMRC)] and the six-minute distance test (6MWD). The Kaplan-Meier curve followed by a Log rank test was used to evaluate mortality rate related to eosinophil cutoff point categorization. Multivariate Cox regression analysis was performed to identify the association between eosinophils and mortality with all subjects evaluated at baseline, adjusted for age, gender, mMRC, 6MWT, forced expiratory volume in the first second (FEV1) and SpO2. RESULTS: Nineteen patients did not complete follow-up and it was not possible to identify the date of death in four others. Therefore, 110 patients were included in the analysis. At baseline, 81% presented ≥150 eosinophil cells and 72% presented ≥2%. We identified a three-fold higher risk of death in those with <2% eosinophils and <150 cells. We did not identify statistical differences when using other cutoff points. CONCLUSION: The decrease in number of peripheral eosinophils, with cutoff points at 2% and 150 cells, may be associated with a higher risk of death in COPD patients over nine years.

RESUMO

BACKGROUND: Brazil is an upper middle-income country in South America with the world's sixth largest population. Despite great advances in health-care services and cardiac surgical care in both its public and private health systems, little is known on the volume, outcomes, and trends of coronary artery bypass grafting (CABG) in Brazil's public health system. OBJECTIVE: The aim of this study was to evaluate the outcome of CABG on the public health system from January 2008 to December 2017 through the database DATASUS. METHODS: This study is based on publicly available material obtained from DATASUS, the Brazilian Ministry of Health's data processing system, on numbers of surgical procedures, death rates, length of stay, and costs. Only isolated CABG procedures were included in our study. We used the TabNet software from the DATASUS website to generate reports. The χ2 test was used to compare death rates. A p < .05 was considered statistically significant. RESULTS: We identified 226,697 CABG procedures performed from January 2008 to December 2017. The overall in-hospital mortality over the 10-year period was 5.7%. We observed statistically significant differences in death rates between the five Brazilian macro-regions. Death rates by state ranged from 2.6% to 13.1%. The national average mortality rate remained stable over the course of time. CONCLUSION: Over 10 years, a high volume of CABG was performed in the Brazilian Public Health System, with significant differences in mortality, number of procedures, and distribution of surgeries by region. Future databases involving all centers that perform CABG and carry out risk-adjusted analysis will help improve Brazilian results and enable policymakers to adopt appropriate health-care policies for greater transparency and accountability.

RESUMO

BACKGROUND: Vitamin D (VD) deficiency affects individuals of different ages in many countries. VD deficiency may be related to several diseases, including cancer. OBJECTIVE: This study aimed to review the relationship between VD deficiency and cancer. METHODS: We describe the proteins involved in cancer pathogenesis and how those proteins can be influenced by VD deficiency. We also investigated a relationship between cancer death rate and solar radiation. RESULTS: We found an increased bladder cancer, breast cancer, colon-rectum cancer, lung cancer, oesophagus cancer, oral cancer, ovary cancer, pancreas cancer, skin cancer and stomach cancer death rate in countries with low sunlight. It was also observed that amyloid precursor protein, ryanodine receptor, mammalian target of rapamycin complex 1, and receptor for advanced glycation end products are associated with a worse prognosis in cancer. While the Klotho protein and VD receptor are associated with a better prognosis in the disease. Nfr2 is associated with both worse and better prognosis in cancer. CONCLUSION: The literature suggests that VD deficiency might be involved in cancer progression. According to sunlight data, we can conclude that countries with low average sunlight have high cancers death rate. New studies involving transcriptional and genomic data in combination with VD measurement in long-term experiments are required to establish new relationships between VD and cancer.

RESUMO

INTRODUCTION: Although a considerable improvement in survival of patients with acute promyelocytic leukemia (APL) has been seen over the past decades, real-life outcomes seem to be worse than those reported by prospective studies. We aim to describe clinical characteristics and outcomes of adult patients diagnosed with APL in an academic hospital from the University of Sao Paulo. PATIENTS AND METHODS: We retrospectively reviewed the medical charts of 61 patients with APL diagnosed between January 2007 and May 2017. Baseline clinical features and follow-up data were collected, focusing on early toxicity variables such as infection, bleeding, and thrombosis in the first 30 days from diagnosis. RESULTS: Among the 61 patients with APL, 54 received any chemotherapy. All patients also received all-trans retinoic acid (ATRA). Bleeding events were the main cause of death before receiving chemotherapy. Most patients belonged to the intermediate (43%) and high-risk (41%) groups, according to Sanz score. The '7 + 3 + ATRA' regimen was the most used regimen (n = 38). An early death rate of 20% was found, predominantly owing to sepsis. After a median follow-up of 5 years, only 1 relapse was diagnosed. The overall survival at 5 years was 59%. DISCUSSION: In comparison with prospective trials with ATRA-based regimens, we found an inferior overall survival, mostly on account of a high early-death rate. Our results are in line with other real-life retrospective reports published in the past decades. CONCLUSION: Results of real-life studies differ from those found by prospective trials. Accordingly, early actions and supportive care are still needed, aiming to decrease toxicity, especially in developing countries.

RESUMO

Se realizó un estudio descriptivo y transversal de los 9 211 fallecidos por todas las causas en la provincia de Santiago de Cuba durante 2017, con vistas a describir el perfil de mortalidad en ese período. En la serie se observó un incremento de la mortalidad general con respecto a 2016; asimismo, como causas principales de muerte figuraron las enfermedades del corazón, los tumores malignos y las enfermedades cerebrovasculares. Los municipios que dominaron el perfil de mortalidad fueron Contramaestre, San Luis, Songo-La Maya, Santiago de Cuba y III Frente, principalmente por las enfermedades del corazón. Por otra parte, el mayor riesgo de morir por tumores malignos en las féminas obedeció a la localización en pulmón, mama e intestino, excepto en el recto; en los hombres, en próstata, pulmón y colon, respectivamente. Se recomienda dirigir las acciones en salud según el riesgo estratificado en esta provincia.


A descriptive and cross-sectional study of the 9 211 dead patients due to all causes was carried out in Santiago de Cuba province during 2017, with the aim of describing the mortality profile in that period. In the series an increment of the general mortality was observed when compared to 2016; also, as main causes of death there were heart diseases, malignant tumors and cerebrovascular diseases. The municipalities that prevailed in the mortality profile were Contramaestre, San Luis, Songo-La Maya, Santiago de Cuba and III Frente, mainly due to heart diseases. On the other hand, the greatest risk of dying due to malignant tumors in the female patients obeyed to the localization in lung, breast and intestine, except in the rectum; in the men, in prostate, lung and colon, respectively. It is recommended to direct the efforts in health according to the stratified risk in this province.

RESUMO

Vitamin D (VD) deficiency is a growing problem, affecting a significant portion of the population in many countries. VD deficiency may be related to several diseases, including Alzheimer's disease (AD). This study aimed to review the relationship between VD deficiency and AD. We describe the proteins involved in AD pathogenesis and how those proteins can be influenced by VD deficiency. We also investigated a relationship between AD death rate and solar radiation and we found an increased AD death rate in countries with low sunlight. It was also observed that amyloid precursor protein, ryanodine receptor, mammalian target of rapamycin complex 1, and receptor for advanced glycation end products are associated with a worse prognosis in AD. While the Klotho protein, phosphatase and tensin homologue, and VD receptor are associated with a better prognosis in the disease. The literature suggests that decline in VD concentrations may be involved in the establishment and progression of AD. According to sunlight data, we can conclude that countries with low average sunlight have high AD death rate.

RESUMO

Abstract This paper describes the construction of the BR-EMS 2015 mortality tables for the Brazilian insured population. The tables were based on data collected from insurance companies which represent about 80 per cent of the Brazilian insurance market, and they are updates of their previous versions, BR-EMS 2010, which have been the first mortality tables built with Brazilian market experience. Additional data from government sources was used to improve the information of the companies’ databases. The mortality rates of the population under risk products (death coverage) are remarkably different than those under savings products (survivorship coverage); as such, four different mortality tables are constructed, separating the population by sex as well as the type of insurance coverage. A straight comparison between the BR-EMS 2015 tables with the statistics of the general Brazilian population shows a striking difference on life expectancies. The BR-EMS 2015 tables are also compared with other life tables.


Resumo Este artigo descreve a construção das tábuas de mortalidade BR-EMS 2015 para a população brasileira de segurados. As tábuas foram elaboradas a partir de dados coletados de companhias de seguros que representam 80% do mercado segurador brasileiro e são atualizações das tábuas BR-EMS 2010, que foram as primeiras tábuas de mortalidade a serem produzidas usando-se a experiência do mercado segurador brasileiro. Informações adicionais de fontes governamentais foram utilizadas para complementar e melhorar as informações fornecidas pelas companhias de seguros. As taxas de mortalidade da população contratante de produtos com cobertura de morte são notavelmente diferentes daquelas referentes aos contratantes de produtos de sobrevivência. Assim, quatro tábuas de mortalidade diferentes foram construídas, separando a população por sexo e também pelo tipo de cobertura de seguro. Uma comparação direta entre as tábuas BR-EMS 2015 com as estatísticas da população brasileira geral mostra uma diferença considerável nas expectativas de vida. As tábuas BR-EMS 2015 ainda são comparadas com outras tábuas de mortalidade.


Resumen En este trabajo se describe la construcción de las tablas de mortalidad BR-EMS 2015 para la población asegurada de Brasil. Las tablas se confeccionaron a partir de datos recogidos de las compañías de seguros que representan alrededor del 80% del mercado brasileño de seguros y son actualizaciones de sus versiones anteriores, BR-EMS 2010 —las primeras tablas de mortalidad hechas con base en la experiencia del mercado brasileño—. Se utilizó información adicional de fuentes gubernamentales para complementar y mejorar las bases de datos de las empresas. Las tasas de mortalidad de la población con contrato de productos de riesgo (cobertura de la muerte) son notablemente diferentes a las de los incluidos en los productos de ahorro (cobertura de supervivencia). Por lo tanto, cuatro diferentes tablas de mortalidad se han construido, separando la población según el sexo y el tipo de cobertura de seguro. Una comparación directa entre las tablas BR-EMS 2015 para la población asegurada de Brasil con las estadísticas de la población en general de Brasil muestra una diferencia considerable en la esperanza de vida. Las tablas BR-EMS 2015 también se comparan con otras tablas de vida.

RESUMO

We investigated the prognostic effects of high-flux hemodialysis (HFHD) and low-flux hemodialysis (LFHD) in patients with chronic kidney disease (CKD). Both an electronic and a manual search were performed based on our rigorous inclusion and exclusion criteria to retrieve high-quality, relevant clinical studies from various scientific literature databases. Comprehensive meta-analysis 2.0 (CMA 2.0) was used for the quantitative analysis. We initially retrieved 227 studies from the database search. Following a multi-step screening process, eight high-quality studies were selected for our meta-analysis. These eight studies included 4967 patients with CKD (2416 patients in the HFHD group, 2551 patients in the LFHD group). The results of our meta-analysis showed that the all-cause death rate in the HFHD group was significantly lower than that in the LFHD group (OR=0.704, 95%CI=0.533-0.929, P=0.013). Additionally, the cardiovascular death rate in the HFHD group was significantly lower than that in the LFHD group (OR=0.731, 95%CI=0.616-0.866, P<0.001). The results of this meta-analysis clearly showed that HFHD decreases all-cause death and cardiovascular death rates in patients with CKD and that HFHD can therefore be implemented as one of the first therapy choices for CKD.

RESUMO

OBJECTIVE: To characterize the deaths of 193 children with sickle cell disease screened by a neonatal program from 1998 to 2012 and contrast the initial years with the final years. METHODS: Deaths were identified by active surveillance of children absent to scheduled appointments in Blood Bank Clinical Centers (Hemominas). Clinical and epidemiological data came from death certificates, neonatal screening database, medical records, and family interviews. RESULTS: Between 1998 and 2012, 3,617,919 children were screened and 2,591 had sickle cell disease (1:1,400). There were 193 deaths (7.4%): 153 with SS/Sß0-talassemia, 34 SC and 6 Sß+thalassemia; 76.7% were younger than five years; 78% died in the hospital and 21% at home or in transit. The main causes of death were infection (45%), indeterminate (28%), and acute splenic sequestration (14%). In 46% of death certificates, the term "sickle cell" was not recorded. Seven-year death rate for children born between 1998 and 2005 was 5.43% versus 5.12% for those born between 2005 and 2012 (p = 0.72). Medical care was provided to 75% of children; 24% were unassisted. Medical care was provided within 6 hours of symptom onset in only half of the interviewed cases. In 40.5% of cases, death occurred within the first 24 hours. Low family income was recorded in 90% of cases, and illiteracy in 5%. CONCLUSIONS: Although comprehensive and effective, neonatal screening for sickle cell disease was not sufficient to significantly reduce mortality in a newborn screening program. Economic and social development and increase of the knowledge on sickle cell disease among health professionals and family are needed to overcome excessive mortality. .


OBJETIVO: Caracterizar os 193 óbitos de crianças com doença falciforme diagnosticadas por programa de triagem neonatal entre 1998-2012 e comparar os primeiros com os últimos anos. MÉTODOS: Os óbitos foram identificados pela busca ativa das crianças ausentes nas consultas agendadas nos hemocentros. Dados clínicos e epidemiológicos provieram dos documentos de óbito, banco de dados da triagem neonatal, prontuários médicos e das entrevistas com parentes. RESULTADOS: Entre 1998-2012 foram triadas 3.617.919 crianças, 2.591 com doença falciforme (1:1.400). Ocorreram 193 óbitos (7,4%): 153 com SS/Sß0-talassemia, 34 SC e 6 Sß+-talassemia; 76,7% em crianças com menos de cinco anos; 78% faleceram em hospitais e 21% em domicílio ou trânsito. Causas principais do óbito: 45% infecção, 28% indeterminada, 14% sequestro esplênico agudo. Em 46% dos documentos de óbito, não houve registro do termo "falciforme". A taxa de mortalidade até sete anos das crianças nascidas entre 1998-2005 foi 5,43% versus 5,12%, entre 2005-2012 (p = 0,72). Receberam assistência médica 75% das crianças; 24% ficaram desassistidas. Pelas entrevistas, atendimento médico teria ocorrido nas primeiras seis horas do início dos sintomas em metade dos casos. O óbito ocorreu em 40,5% dos casos, nas primeiras 24 horas. Baixa renda familiar foi registrada em 90% dos casos e analfabetismo em 5%. CONCLUSÕES: A triagem para doença falciforme, mesmo abrangente e eficaz, não foi suficiente para reduzir significativamente a mortalidade no Programa de Triagem Neonatal. Necessita-se de desenvolvimento econômico e social do Estado e ampliação, pela educação continuada, do conhecimento sobre a doença falciforme entre os profissionais de saúde e parentes. .

RESUMO

BACKGROUND: Children in developing countries with sickle cell disease SCD have high rates of mortality, especially in some parts of Africa. AIM: To compare the 5-year estimated mortality rate in children born between 1999 and 2001 with that of children born between 2009 and 2011. METHODS: During the period 1998-2012, sickle cell disease was diagnosed in 2591 of 3,617,919 newborns screened in Minas Gerais, Brazil (1 : 1,400). The estimated probability of death [1 - Survival] was calculated by the Kaplan-Meier method. The logrank test was used to compare groups of survival data. RESULTS: Of the 2576 children (15 were excluded), 193 died (7.4%): 153 (79.3%) had SS/Sß(0)-thalassaemia, 34 had SC (17.6%), and six (3.1%) had Sß(+) thalassaemia. The 5-year estimated mortality was lower for children born between 2009 and 2011 (n=509) than for those born between 1999 and 2001 (n=624), although not significantly [mean (SD) 5.8% (1.1) vs 6.2% (1.0)], respectively). CONCLUSION: Despite an effective ongoing comprehensive screening programme, mortality from SCD in Minas Gerais is still high. To decrease mortality rates, socio-economic development and SCD education programmes for health professionals and families are required.

RESUMO

OBJECTIVES: Non-communicable diseases have become the leading cause of death in middle-income countries, but mortality from injuries and infections remains high. We examined the contribution of specific causes to disparities in adult premature mortality (ages 25-64) by educational level from 1998 to 2007 in Colombia. METHODS: Data from mortality registries were linked to population censuses to obtain mortality rates by educational attainment. We used Poisson regression to model trends in mortality by educational attainment and estimated the contribution of specific causes to the Slope Index of Inequality. RESULTS: Men and women with only primary education had higher premature mortality than men and women with post-secondary education (RRmen=2.60, 95% confidence interval [CI]: 2.56, 2.64; RRwomen=2.36, CI: 2.31, 2.42). Mortality declined in all educational groups, but declines were significantly larger for higher-educated men and women. Homicide explained 55.1% of male inequalities while non-communicable diseases explained 62.5% of female inequalities and 27.1% of male inequalities. Infections explained a small proportion of inequalities in mortality. CONCLUSION: Injuries and non-communicable diseases contribute considerably to disparities in premature mortality in Colombia. Multi-sector policies to reduce both interpersonal violence and non-communicable disease risk factors are required to curb mortality disparities.
