RESUMO

OBJECTIVES: In Chile, colorectal cancer (CRC) is the fourth cause of death by cancer. Few studies have evaluated the role of contextual and individual socio-economic variables associated with premature death by CRC (<70 years). We analyzed the association between socio-economic factors (at individual and contextual levels) and premature death from CRC in Santiago de Chile. STUDY DESIGN: This was a cross-sectional study. METHODS: We analyzed deaths from CRC between 2014 and 2018 using data published by the Ministry of Health. Individual predictors were sex, marital status, and educational level. Contextual variable included the Social Priority Index (SPI) of the commune where the deceased lived. The association was assessed through multilevel logistic regression models. RESULTS: During the period, 4762 deaths occurred (51.7% women); 39.3% were premature. At the individual level, male sex (odds ratio [OR] 1.36; 95% confidence interval [CI] 1.20-1.53) and single marital status (OR 1.45; 95% CI 1.24-1.68) were associated with premature death from CRC. Primary or lower education was a protective factor (OR 0.53; 95% CI 0.47-0.60). At the contextual level, communes with a higher SPI were three times more at risk than those with a lower SPI (OR 3.13; 95% CI 2.15-4.57). CONCLUSIONS: This study showed that individual and contextual socio-economic variables are related to premature death from CRC. Residing in communes with greater socio-economic vulnerability was associated with greater risk. To reduce this gap, it is urgent to design and implement structural policies to reduce social inequities and improve access to health care.

RESUMO

Objetivo: Estimar los años potenciales de vida perdidos y la distribución espacial de la mortalidad por incidente vial según modo de transporte en Medellín 2010-2020, como línea base para la implementación de la estrategia Visión Cero, de la Organización Mundial de la Salud, en la movilidad de la ciudad. Metodología: Estudio retrospectivo y descriptivo de corte transversal, con fuente secundaria. El cálculo de los años potenciales de vida perdidos se hizo tomando como edad límite la esperanza de vida al nacer de Colombia, según año y género. El análisis espacial se realizó a partir de la dirección del incidente; la representación de la densidad de Kernel fue por el método de clasificación estándar-cuantil, y las zonas de influencia se crearon por el método búfer de anillos múltiples, con distancias de 500 y 1000 metros. Resultados: Medellín, entre 2010 y 2020, registró 2988 muertes por incidente vial. Quienes más murieron fueron los peatones, con 1423 (47,6 %) muertes, seguidos por los motociclistas, con 1295 (43,3 %). Los años potenciales de vida perdidos fueron 98 787. Las comunas de mayor concentración en muerte de peatones fueron: Candelaria, Buenos Aires y Manrique; en motociclistas, la mayor concentración se evidenció en el sistema vial del río. Por zonas de influencia, los peatones fallecidos en un radio de 1000 metros del sistema vial del río fueron 688 (49,8 %), y los motociclistas, 636 (52,2 %). Conclusión: Los motociclistas fueron quienes murieron más jóvenes y más años dejaron de vivir. Politraumatismos son diagnósticos constantes de muerte, pero lesiones en cabeza, cráneo y tórax son más letales en peatones y motociclistas.

Objective: To estimate the potential years of life lost and the spatial distribution of mortality from road incidents by mode of transport in Medellín 2010-2020, as a baseline for the implementation of the Vision Zero strategy of the World Health Organization in the city's mobility. Methodology: This is a retrospective and descriptive cross-sectional study, with a secondary source. The calculation of the potential years of life lost was made using the life expectancy at birth in Colombia as the age limit, according to year and gender. The spatial analysis was carried out from the direction of the incident; Kernel density was represented by the standard-quantile classification method, and the zones of influence were created by the multiple ring buffer method, with distances of 500 and 1000 meters. Results: Between 2010 and 2020, Medellín registered 2,988 deaths due to road incidents. Those who died the most were pedestrians, with 1,423 (47.6%) deaths, followed by motorcyclists, with 1,295 (43.3%). Potential years of life lost were 98,787. The zones (comunas) with the highest concentration of pedestrian deaths were: Candelaria, Buenos Aires and Manrique; in motorcyclists, the highest concentration was evidenced in the river road system. By areas of influence, pedestrians killed within a radius of 1,000 meters from the river road system were 688 (49.8%), and motorcyclists, 636 (52.2%). Conclusion: Motorcyclists were the ones who died the youngest and the most years they stopped living. Polytrauma is a constant diagnosis of death, but injuries to the head, skull and thorax are more lethal in pedestrians and motorcyclists.

Objetivo: Estimar os anos potenciais de vida perdidos e a distribuição espacial da mortalidade por incidente de trânsito segundo o modo de transporte em Medellín 2010-2020, como linha base para a implementação da estratégia Visão Zero, da Organização Mundial da Saúde, na mobilidade da cidade. Metodologia: Estudo retrospectivo e descritivo de corte transversal, com fonte secundária. O cálculo dos anos potenciais de vida perdidos foi feito considerando como idade limite a esperança de vida ao nascer da Colômbia, segundo ano e gênero. A análise espacial realizou-se a partir do local do incidente; a representação da densidade de Kernel foi pelo método de classificação padrão-quantil, e as zonas de influência criaram-se pelo método buffer de anéis múltiplos, com distâncias de 500 e 1000 metros. Resultados: Medellín, entre 2010 e 2020, registrou 2988 mortes por incidente de trânsito. O maior número de mortes foi de pedestres, sendo 1423 (47,6%), seguido pelo de motoqueiros, sendo 1295 (43,3%). Os anos potenciais de vida perdidos foram 98.787. As localidades com maior concentração de mortes de pedestres foram: Candelaria, Buenos Aires e Manrique; no caso dos motoqueiros, a maior concentração evidenciou-se no sistema viário do rio. Por zonas de influência, os pedestres falecidos em um raio de 1000 metros do sistema viário do rio foram 688 (49,8%), e os motoqueiros 636 (52,2%). Conclusão: Os motoqueiros foram quem morreram mais novos e mais anos deixaram de viver. Politraumatismos são diagnósticos constantes de morte, mas lesões na cabeça, no crâneo e no tórax são mais letais em pedestres e motoqueiros.

RESUMO

Background: The consumption of processed meat causes negative impacts on health; however, this burden for the population living in developing countries is less explored. This study aimed to describe the burden of chronic noncommunicable diseases (NCDs) attributed to a diet rich in processed meat between 1990 and 2019 in Brazil and its federative units and the financial burden on the Unified Health System (SUS) in 2019. Methods: Secondary data from the Global Burden of Disease (GBD) and SUS Information Systems were used in this ecological study. The metrics to assess the burden of NCDs attributable to processed meat consumption were disability-adjusted life years (DALYs) and deaths. The age-standardized rates were presented per 100,000 inhabitants with 95% uncertainty intervals (95% UI). The cost of hospitalizations and outpatient procedures covered by SUS for the treatment of NCDs attributable to processed meat consumption was estimated using the population-attributable fraction. Both burdens were estimated for both sex and stratified by sex, specific cause, and federative units. Results: The age-standardized DALY rates attributable to a diet rich in processed meat increased between 1990 (75.31/100,000 [95% UI: 34.92-139.65]) and 2019 (79.35/100,000 [95% UI: 42.84-126.25]); while mortality rates remained stable between 1990 (2.64/100,000 [95% UI: 1.17-5.21) and 2019 (2.36/100,000 [95% UI: 1.22-4.09]). The cost of hospitalization and outpatient procedures in Brazil for NCDs attributable to the consumption of processed meat was approximately US$ 9,4 million, of which US$ 6,1 million was spent on ischemic heart disease, US$ 3,1 million on colorectal cancer, and US$ 200 thousand on type 2 diabetes mellitus. Conclusion: The NCD burden did not decrease during the years evaluated, while the financial burden was high in 2019, with higher treatment costs for ischemic heart disease. These results can guide political, economic, and health education interventions to advance the fight against NCDs.

RESUMO

Gastric cancer (GC) is the fifth most common type of tumor and the third leading cause of cancer death worldwide. The evolution of gastric carcinogenesis is still poorly understood and, for this reason, preclinical research protocols were established that included the development of gastric cancer cell lines and the establishment of models of gastric carcinogenesis in non-human primates such as Sapajus apella. A comprehensive literature search was performed in relevant databases such as PubMed, ResearchGate, and Google Scholar to identify studies related to the topic. After an in-depth study of these reports, significant data were collected and compiled under appropriate headings. The main result of the studies carried out by the group on GC is the demonstration of the MYC gene overexpression as a common phenomenon in stomach carcinogenesis. Furthermore, we revealed that reducing the expression of the CDC25B gene, regulated by the MYC protein, is a therapeutic strategy against stomach tumors. This review article reveals preclinical evidence that treatment with menadione in experimental models of gastric tumorigenesis, in vivo and in vitro, inhibits the action of the phosphatase CDC25B and, consequently, prevents cell proliferation, invasion, and migration.

RESUMO

Abstract INTRODUCTION: Suicide deaths varies according to location, sex, and age. This study analyzed the Global Burden of Disease Study 2019 (GBD 2019) concerning suicide in Brazil. METHODS: This study described the mortality and years of life lost (YLL) due to premature death caused by suicide in Brazil in 1990 and 2019. The numbers, crude and age-standardized mortality rate (ASMR), and YLL were compared among Brazilian states, age groups, and sexes. RESULTS: There were 13,502 suicides in Brazil in 2019, 46.00% more than in 1990. The crude mortality rate increased 0.32%, while the ASMR declined -21.68% during the period. Crude and age-standardized YLL rates declined by -7.24% and -18.38%, respectively. In 2019, the biggest ASMRs were found in the South, whereas from 1990 to 2019, the ASMR declined in the South, Southeast, and Midwest, and increased in the Northeast. The number of suicides was higher among individuals aged 15-49 years, and suicide rates were higher among those aged over 70 years. From 1990 to 2019, an increase in the rate was found only of 10-14 years of age. Suicide was highest in men, except in the 10-14-year age group, ranking third in mortality among men of 15-34 years of age and fourth among women of 15-24 years of age. CONCLUSIONS: The ASMR and YLL for suicide declined since 1990, but suicide remains an important factor of mortality in the country. The South Region, men, elderly, and youth should be priorities in the implementation of suicide prevention strategies in Brazil.

RESUMO

O uso de porta-enxertos tolerantes apresenta bons resultados no manejo da murcha de Fusarium (Fusarium solani) no maracujazeiro-amarelo(Passiflora edulis Sims), considerada um dos principais problemas na cultura, que afeta o sistema radicular da planta e não tem controle químico. O presente trabalho teve po robjetivo avaliar a sobrevivência, o desempenho agronômico de plantas e as características físicas de frutos de maracujazeiro-amarelo (Passiflora edulis Sims) enxertadas em diferentes porta-enxertos em área com murcha de Fusarium. O experimento foi conduzido no Sítio Bela Vista, localizado no município de Pracinha, SP, no período de agosto de 2014 a maio de 2015, e adotou-se o delineamento em blocos ao acaso, com cinco tratamentos, cinco repetições e quatro plantas por parcela. Os tratamentos utilizados foram os porta-enxertos: P. alata Dryand, P. gibertii N.E. Brown, P. caerulea Linnaeus, enxertia dupla P.gibertiix P.edulise plantas sem enxerto. Avaliaram-se o diâmetro do caule do porta-enxerto e do enxerto, o comprimento de ramos secundários, o número de ramos terciários, o número de plantas sobreviventes, os diâmetros longitudinal e transversal dos frutos, o número e a massa de frutos e a produtividade. O maior diâmetro do porta-enxerto foi observado em Passiflora alata enquanto que na região do enxerto foi em plantas de Passiflora edulis. O comprimento dos ramos secundários e o número de ramos terciários foram afetados pelo tipo de enxertia e pelo porta-enxerto utilizado. As maiores sobrevivências de plantas foram observadas em Passiflora alata (90%)e Passifloragibertii (100%).O maior número de frutos por planta e produtividade ocorreram em plantas enxertadas sobre P. gibertii.A adoção da enxertia dupla utilizando-se Passiflora gibertii x Passiflora edulis e a enxertia simples com Passiflora caerulea não se mostraram eficientes no controle desta doença. As espécies Passiflora gibertiie Passiflora alata apresentaram potencial para serem utilizados como porta-enxertos para o maracujazeiro-amarelo.

The use of tolerant rootstocks has shown good results in the control of Fusarium wilt in yellow passion fruit, which is considered one of the main problems in the crop as it affects the plant’s root system and has no chemical control. The present study aimed to evaluate the survival rates, the agronomic performance of the plants and the physical characteristics of the yellow passion fruit (Passiflora edulisSims) grafted on different root stocks in area with Fusarium wilt. The experiment was carried in Pracinha, in the State of São Paulo, Brazil, from August 2014 to May 2015, and a randomized block design was adopted, with five treatments, five replications and four plants per plot. The treatments were constituted by the following rootstocks: Passiflora alata Dryand, Passiflora gibertii N.E. Brown, Passiflora caerulea Linnaeus, double grafting P. gibertii x P. edulis and plants without grafting. The stem diameter of rootstock and the graft, the lenght of secondary branches, the number of tertiary branches, the number of surviving plants, the longitudinal and transversal diameters of the fruits, the number and mass of fruits and the productivity were evaluated. The largest diameter of the rootstock was observed in Passiflora alata while in the graft it was in plants of Passifloraedulis. The length of the secondarty branches and the number of tertiary branches were affected by the type of grafting and the rootstock used. The highest survival rates were observed in Passiflor aalata (90%)and Passiflora gibertii (100%).The highest number of fruits per plant and productivity occurred in plants grafted on Passiflora gibertii. The adoption of double grafting using Passiflora gibertii x Passiflora edulis and simple grafting with Passiflora caerulea were not effective in the control of this disease. The species Passiflora gibertii and Passiflora alata showed the potential to be used as a rootstock for yellow passion fruit.

RESUMO

Introducción: Los accidentes de tránsito constituyen un grave problema de salud pública, sin embargo, su impacto socioeconómico no se conoce en el Paraguay. Objetivos: determinar el impacto socioeconómico de los accidentes de moto en <19 años en el año 2016. Materiales y Métodos: estudio descriptivo, observacional, retrospectivo. Se incluyeron todos los pacientes ≤19 años que acudieron al Hospital de Trauma (HT) con antecedente de accidente de moto en el año 2016. Los datos y los costos fueron obtenidos de la base de datos del Dpto. de Estadísticas y del Dpto. de Ingresos del HT, respectivamente. Resultados: se incluyeron 700 pacientes que acudieron al HT por accidente de moto. La edad media de los pacientes fue de 15,6 ± 4.33 años. El 78% (546/700) era de sexo masculino. De los accidentados 450 (64,2%) era conductor y 250 (35,7%) acompañante. La media de edad de los conductores fue de 17 ± 4,3 años (rango 11 - 19 años) y de los acompañantes 12,3 ± 4,4 (rango <1 - 19 años). Entre los conductores solo el 50.4% (227/450) tenía la edad reglamentaria para obtener licencia de conducir. Solo el 7,7% (54/695) de los accidentados usaba casco al momento del accidente. Requirió hospitalización por 2 o más días el 89,2% (625/700) de los pacientes, de los cuales el 7.6% requirió ser hospitalizado en UCIP. La media de días de hospitalización en sala y UCIP fue de 11.04 días (DS 14,85 días) y 16.57 (DS 23 días). El 25,1% (176/700) tuvo algún grado de discapacidad o secuela y el 5,4% (38/700) falleció. Los costos directos por hospitalización por día en sala y en UCIP fueron de 275,4 y 737,2 $, respectivamente. Los costos directos por accidentes de moto en el año 2016 fue de 2.587.179,2$. Los años de vida potencialmente perdidos (AVPP) en el año 2016, fueron de 2159 años. Conclusiones: El impacto socioeconómico de los accidentes de motos, representa un costo social extremo derivado de una causa de muerte que podría prevenirse.

Introduction: Traffic accidents are a serious public health problem, however, their socio-economic impact has not been described in Paraguay. Objectives: to determine the socioeconomic impact of motorcycle accidents in victims <19 years of age in 2016. Materials and Methods: this was a descriptive, observational, retrospective study. All patients aged ≤19 years who were admitted to the Trauma Hospital (TH) with a history of a motorcycle accident in 2016 were included. The data and costs were obtained from the Statistics Department and the Admissions Department of the TH. Results: 700 patients were included, all of whom were admitted to the TH due to a motorcycle accident. The average age of the patients was 15.6 ± 4.33 years. 78% (546/700) were male. Of those injured, 450 (64.2%) were drivers and 250 (35.7%) were passengers. The average age of the drivers was 17 ± 4.3 years (range 11-19 years) and that of the passengers was 12.3 ± 4.4 years (range <1-19 years). Among the drivers, only 50.4% (227/450) were of the legal age to obtain a driver's license. Only 7.7% (54/695) of the victims wore a helmet at the time of the accident. 89.2% (625/700) of patients required hospitalization stays of 2 or more days of length, of which 7.6% required PICU admission. The mean number of regular ward hospitalization days and PICU days were 11.04 days (SD 14.85 days) and 16.57 days (SD 23 days), respectively. 25.1% (176/700) had some degree of disability or long-term effects and 5.4% (38/700) died. The direct costs per hospitalization per day in the ward and in the PICU were US$ 275.4 and 737.2, respectively. The direct costs for motorcycle accidents in 2016 was US$ 2,587,179.2. The years of potential life lost (YPLL) in 2016 were 2159 years. Conclusions: The socioeconomic impact of motorcycle accidents represents an extremely high social cost, stemming from a preventable cause of death.

RESUMO

BACKGROUND: Leukemias are the leading cause of childhood cancer. In most developed countries 1-2% of patients die during remission induction; however, in developing countries, this figure is higher and the causes of death apparently vary among the populations studied. The aim was to determine the cause of death during remission induction in pediatric patients with acute lymphoblastic leukemia (ALL) in the hospital "Dr. Gaudencio González Garza" of Centro Médico Nacional La Raza from January 1, 2009, to December 31, 2014. METHODS: A retrospective cohort study was carried out and a descriptive statistical analysis was performed. RESULTS: During the study period, a total of 463 patients with ALL were diagnosed, out of which 5.4% died (n = 25). Among the patients who died, 64% (n = 16) were female and 60% had high-risk clinical features at diagnosis. The main causes of death were septic shock and bleeding. CONCLUSIONS: Early mortality was five times higher than the one reported for developed countries, while the causes of death did not differ. Close monitoring is necessary to detect and promptly treat complications secondary to chemotherapy toxicity in Mexican pediatric patients with ALL.

Introducción: las leucemias son la principal causa de cáncer en la infancia. En la mayoría de países desarrollados fallecen entre 1 y 2% de los pacientes durante la inducción a la remisión; sin embargo, en países en vías de desarrollo, esta cifra al parecer es superior y las causas de muerte varían entre las poblaciones estudiadas. El objetivo fue determinar la causa de mortalidad durante la fase de inducción a la remisión en los pacientes pediátricos con diagnóstico de leucemia linfoblástica aguda (LLA) en el Hospital General "Dr. Gaudencio González Garza" del Centro Médico Nacional La Raza del 1 de enero de 2009 al 31 de diciembre de 2014. Métodos: se realizó un estudio de cohorte retrospectivo y se utilizó estadística descriptiva. Resultados: se diagnosticaron un total de 463 pacientes con LLA durante el periodo de estudio, de los cuales falleció el 5.4% (n = 25). Entre los pacientes que fallecieron, el 64% (n = 16) eran del sexo femenino y el 60% tenía características clínicas de alto riesgo al momento del diagnóstico. Entre las principales causas de muerte estuvieron el choque séptico y las hemorragias. Conclusiones: la frecuencia de mortalidad temprana en los pacientes con LLA fue cinco veces más elevada que la reportada para países desarrollados, mientras que las causas de muerte no difieren. Se requiere de una vigilancia estrecha para detectar y tratar oportunamente las complicaciones secundarias a toxicidad por quimioterapia en pacientes pediátricos mexicanos con LLA.

RESUMO

OBJECTIVE: To explore the clinical prognostic factors for adults affected with astrocytoma. PATIENTS AND METHODS: Using a historic cohort, we selected 155 clinical files from patients with astrocytoma using simple randomization. The main outcome variable was overall survival time. To identify clinical prognostic factors, we used bivariate analysis, Kaplan Meier, the log rank test and the Cox regression models. The number of lost years lived with disability (DALY) based on prevalence, was calculated. RESULTS: The mean age at diagnosis was 45.7 years. Analysis according to tumour stage, including grades II, III and IV, also showed a younger age of presentation. Kaplan-Meier survival estimates showed that tumour grade, Karnofsky status (KPS) ≥70, resection type, chemotherapy, radiotherapy, alcohol consumption, familial history of cancer and clinical presentation were significantly associated with survival time. Using a proportional hazard model, age, grade IV, resection, chemotherapy+radiotherapy and KPS were identified as prognostic factors.The amount of life lost due to premature death in this population was 28 years. CONCLUSION: In our study, astrocytoma was diagnosed in young adults. The overall survival was 15 months, 9% (n=14) of patients presented a survival of 2 years, and 3% of patients survived 3 years. On average the number of years lost due to premature death and disability was 28.53 years.

RESUMO

Introducción: La aparición prematura de la enfermedad coronaria en una misma familia ha sido reconocida y se ha establecido como un factor de riesgo independiente de la enfermedad coronaria, se han demostrado cambios a corto plazo en la expresión genética en respuesta a la dieta, el ejercicio y el manejo del stress, produciendo cambios positivos a nivel molecular. Materiales y métodos: Al haber encontrado evidencia de estudios que apoyan la hipótesis de que la aparición de la enfermedad coronaria prematura es un fuerte factor de riesgo se realizó una revisión utilizando las bases de datos: PubMed, Embase, MEDLINE y Scielo, donde se revisaron los artículos en Ingles y Castellano hasta comienzos del 2014. Desarrollo. Los pacientes con historia parenteral de cardiopatía isquémica, presentaron una mortalidad más elevada a los 35 años, la implicación más importante es el riesgo sostenido de la enfermedad coronaria prematura, la cual comienza mucho antes de que los otros procesos patológicos se conviertan en factores de riesgo tradicionales, se identifiquen y traten, han sido demostrados cambios genéticos y moleculares asociados a mejoría del estado vascular, además existen enzimas capaces de modificar la actuación y eliminación de los medicamentos. Conclusiones: La identificación de un evento coronario en una persona menor de 60 años debe indicar la necesidad urgente de una intervención activa en sus niños, buscando cambios dietéticos, de ejercicios físicos, e intervenciones sobre la tensión arterial, que debe ser continuada y sostenida para reducir factores de riesgo y obtener una mejor adhesión a los medicamentos.

Introduction: The premature appearance of the coronary heart disease in oneself family has been recognized and has settled down as a factor of independent risk of the coronary illness, short term changes have been demonstrated in the genetic expression in response to the diet, the exercise and the handling of the stress, producing positive changes at molecular level. Materials and Methods: When having found evidence of studies that support the hypothesis that the appearance of the premature coronary illness is a strong factor of risk, was carried out a revision using the following databases: PubMed, Embase, MEDLINE and Scielo, where the articles were revised in English and Castellano until beginnings of the 2014. Development: The patients with family history of ischemic heart disease, presented a higher mortality to the 35 years, the most important implication is the sustained risk of the premature coronary illness, which begins a lot before the other pathological processes become traditional factors of risk, are identified and try, genetic and molecular changes associated to improvement of the vascular state have been demonstrated, enzymes also exist able to modify the performance and elimination of the different drugs. Conclusions: The identification of a coronary event in a person smaller than 60 years should indicate the urgent necessity of an active intervention in its children, looking for dietary changes, of physical exercises, and interventions to the blood pressure that should be continued and sustained to reduce factors of risk and to obtain better adhesion to the drugs.

RESUMO

En Cuba varios estudios han estimado la carga de distintas enfermedades y lesiones, empleando como indicador de carga los Años de Vida Potencial Perdidos por Muertes Prematuras, entre otros. La utilidad de estos estudios se debe, especialmente, a su vinculación estrecha con las afectaciones que distintas enfermedades y lesiones provocan en la esperanza de vida. Sin embargo, la estimación de la carga asociada a determinados factores de riesgo es al menos tan importante, sobre todo desde el muy relevante enfoque preventivo y de promoción de salud. En este trabajo se revisan los conceptos básicos vinculados a estos estudios, los pasos fundamentales que requiere su ejecución, y se reflexiona sobre cómo adaptar e implementar estos pasos generales al contexto nacional.

Several studies in Cuba have estimated the burden of several diseases and lesions by using the Potential Years of Life Lost by Premature Death as burden indicator, among others.
