COVID-19 en trabajadores activos durante la cuarentena. Realidad de un sector urbano de Caracas, Venezuela / COVID-19 in active workers during quarantine. Reality of an urban sector of Caracas, Venezuela

La pandemia por COVID-19 resultó un problema para la salud pública mundial, que impactó particularmente al sector de trabajadores que debían trabajar y estar expuestos durante el periodo de cuarentena. Objetivo, analizar la incidencia de COVID-19 y sus características en trabajadores(as) activos(as) durante 34 semanas. Investigación descriptiva y transversal. Población constituida por todos los trabajadores(as) activos de sectores priorizados, con diagnóstico confirmado de COVID-19. De los 1.186 casos confirmados, 658 casos (55%) correspondió a trabajadores activos, una incidencia de 1,7 casos x 1000 (mayor a la esperada), con predominio en trabajadores(as) del sector salud (267casos), choferes del transporte y trabajadores de funerarias (253 casos). El 68,7% menor de 40 años y predominio del sexo masculino (61,2%). En el personal de salud, el 30% correspondió a personal de enfermería y 22% en médicos. La tasa de mortalidad en la población de trabajadores activos fue de 0,07 x cada 1000, con un índice de mortalidad de 0,05 y un índice de recuperación del 95,5%, comportamiento similar al de la población general. Sin embargo, la tasa de letalidad (trabajadores activos positivos fallecidos) fue del 4,4% (29 casos), donde el 75% (22/29) fueron enfermeras y médicos, lo que confirmó al sector salud y trabajadores(as) de servicios, como población trabajadora altamente expuesta y vulnerable, lo que justificó priorizar las medidas de prevención en estos trabajadores, al iniciar el sistema de vigilancia epidemiológica, la vacunación y la dotación con uso adecuado de la protección personal(AU)

The COVID-19 Pandemic was a problem for global public health, which particularly impacted the sector of workers who had to work and were exposed during the quarantine period. The objective was to analyze the incidence of COVID- 19 and its characteristics in active workers during 34 weeks. Descriptive and cross-sectional research. Population made up of all active workers in prioritized sectors, with a confirmed diagnosis of COVID-19. Of the 1,186 confirmed cases, 658 cases (55%) corresponded to active workers, an incidence of 1.7 cases per 1,000 (higher than expected), with a predominance of workers in the health sector (267 cases), transport drivers and funeral home workers (253 cases). 68.7% under 40 years of age and predominance of the male sex (61.2%). In health personnel, 30% corresponded to nursing personnel and 22% to doctors. The mortality rate in the population of active workers was 0.07 x every 1000, with a mortality rate of 0.05 and a recovery rate of 95.5%, behavior similar to that of the general population. However, the fatality rate (deceased positive active workers) was 4.4% (29 cases), where 75% (22/29) were nurses and doctors, which confirmed the health sector and service workers, as a highly exposed and vulnerable working population, which justified prioritizing prevention measures in these workers, by initiating the epidemiological surveillance system, vaccination and provision with adequate use of personal protection(AU)

Correlation between physical activity practice and mortality from COVID-19: an ecological study / Correlação entre prática de atividade física e mortalidade por COVID-19: um estudo ecológico / Correlación entre la práctica de actividad física y la mortalidad por COVID-19: un estudio ecológico

Background and objective: new population-level studies are needed to better assess the relationship between physical inactivity and mortality from COVID-19. The aim of the study was to evaluate the correlation between population prevalence of physical activity and standardized mortality rates by COVID-19 in Brazilian capital cities and the Federal District. Methods: this is an ecological study, whose analysis is secondary. The prevalence of physical inactivity, insufficient physical activity, and physical activity during free time was obtained from the Surveillance of Risk Factors and Protection for Chronic Diseases by Telephone Survey 2019 (VIGITEL), according to minutes spent on leisure, commuting, and household activities. The COVID-19 mortality data was obtained from the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe), adding the accumulated deaths until December 31, 2020. The resident population was estimated from the Instituto Brasileiro de Geografia e Estatística (IBGE) for the year 2020. Pearson Correlation evaluated the correlation between the prevalence of different physical activity practices and the standardized mortality rate from COVID-19, in total, and according to age groups. Results: there was a significant positive correlation (r = 0.420; p = 0.029) between the overall prevalence of insufficient physical activity and the standardized COVID-19 mortality rate. No correlation was observed between the other prevalence of physical activity and the standardized mortality rate from COVID-19. Conclusion: there was a correlation between insufficient levels of physical activity and the standardized mortality rate from COVID-19 in people living in Brazilian capital cities.(AU)

Results: we identified 291,073 hospitalizations and 139,953 deaths; we found higher mortality rates in municipalities with a higher proportion of non-White people (95%CI 1.01;1.16) and with more households with more than two people per room (95%CI 1.01;1.13); presence of sewerage systems was protective for both outcomes (hospitalizations: 95%CI 0.87;0.99 - deaths: 95%CI 0.90;0.99), while a higher proportion of the population in subnormal housing clusters was a risk factor (hospitalizations: 95%CI 1.01;1.16 - deaths: 95%CI 1.09;1.21), with this variable interacting with the proportion of people receiving Emergency Aid (hospitalizations: 95%CI 0.88;1.00 - deaths: 95%CI 0.89;0.98). Conclusion: socioeconomic conditions affected illness and death due to COVID-19 in Brazil.

Hospital mortality rates between 2015 and 2022: a comparison between the pre-pandemic and pandemic period shows that COVID-19 is a critical health problem

Introduction: COVID-19 caused 6.2 million deaths in the world. The present study aims to evaluate hospital mortality rates from 2015 to 2022, to compare the pre and during the pandemic period.Methods: The study was carried out in a private hospital in southern Brazil. 174,013 hospital discharges between January 2015 and March 2022 were analyzed. Pearson's chi-squared test was performed to evaluate the mortality rate by year. Differences between mortality rates before and during the pandemic was tested with Student's t-test. P-values < 0.05 for all tests were considered significant.Results: Mortality rates were 2.29% in 2015; 2.37% in 2016; 2.25% in 2017; 2.31% in 2018; 2.46% in 2019; 3.45% in 2020; 3.58% in 2021 and 2.77% in 2022 (p< 0.01). The mortality for 2020 and 2021 was higher than in the other years (3.50% ± 0.14 vs 2.34% ± 0.05; p < 0.01).Conclusion: The mortality rates were significantly higher in the years 2020 and 2021, demonstrating that COVID-19 is a critical health problem.

Una mirada sociodemográfica a la incidencia de la COVID-19 en Cuba / A socio-demographic look at the incidence of COVID-19 in Cuba

Introducción: En Cuba el comportamiento de la epidemia de la COVID-19 ha sido analizado desde el enfoque de varias ciencias, con la guía de la Epidemiología, para frenar su expansión. Se requiere estudiar su comportamiento atendiendo al estado de la población para identificar sus diferenciales, lo cual puede ayudar en la adopción de medidas para su enfrentamiento. Objetivo: Evaluar la incidencia de la COVID-19 en Cuba a partir de indicadores sociodemográficos. Métodos: Se utilizaron los cálculos de las tasas de incidencia, mortalidad y la letalidad de la COVID-19 por grupos de edades y sexo a nivel de país y sus territorios. Se compararon estas tasas con indicadores demográficos seleccionados. Se utilizaron los datos aportados por diversos sitios oficiales del país en el periodo del 11 de marzo al 12 de junio de 2020. Resultados: La edad fue el principal diferencial de las tasas de mortalidad y la letalidad por COVID-19, con mayor frecuencia en los mayores de 60 años, fundamentalmente en hombres. No se evidenció ninguna variación proporcional entre dichas tasas y el grado de urbanización, la densidad poblacional y el grado de envejecimiento de la población. Conclusiones: Para disminuir el impacto de la COVID-19 en Cuba fueron decisivas las medidas adoptadas por el Gobierno, fundamentalmente las que estaban en función de los grupos más vulnerables. El estudio de los diferenciales de la COVID-19 desde la Demografía constituye un punto de partida para la búsqueda de factores de diversa naturaleza que influyen en su comportamiento(AU)

Introduction: In Cuba, the behavior of the COVID-19 epidemic has been analyzed from the approach of several sciences, with the guidance of Epidemiology, to stop its spread. It is necessary to study its behavior according to the state of the population to identify their differentials, which can help in the adoption of measures to confront them. Objective: Asses the incidence of COVID-19 in Cuba based on socio-demographic indicators. Methods: Calculations of COVID-19 incidence, mortality and lethality rates by age groups and sex were used at the country and territory levels. These rates were compared with selected demographic indicators. The data provided by various official sites of the country in the period from March 11 to June 12, 2020 were used. Results: Age was the main differential in mortality rates and lethality due to COVID-19, with greater frequency in those over 60 years of age, mainly in men. There was no evidence of any proportional variation between these rates and the degree of urbanization, population density and degree of population ageing. Conclusions: To reduce the impact of COVID-19 in Cuba, the measures adopted by the Government were decisive, mainly those that were based on the most vulnerable groups. The study of the differentials of COVID-19 from Demography constitutes a starting point for the search of different nature factors that influence its behavior(AU)

Introducción: El SARS-CoV-2 afecta principalmente al sistema respiratorio, pero el daño producido por este virus también se extiende a otros sistemas, incluido el sistema nervioso, y los mecanismos de infección neurológica pueden ser directos o indirectos. Objetivo: Determinar la relación entre las manifestaciones neurológicas y la severidad de la enfermedad en pacientes sintomáticos positivos a la COVID-19. Hospital San Vicente de Paúl. 2021. Material y Métodos: Estudio observacional de corte transversal, empleando el registro de historias clínicas de los pacientes hospitalizados con la COVID-19 y manifestaciones neurológicas, las cuales se clasificaron en manifestaciones del sistema nervioso central y manifestaciones del sistema nervioso periférico. Resultados: 74,1 por ciento pacientes presentaron manifestaciones neurológicas, el mayor porcentaje se concentró en pacientes que desarrollaron enfermedad grave (15 [60 por ciento], SNC; 91 [77,1 por ciento], SNP; 125 [65,4 por ciento], SNC y SNP). La presencia conjunta de manifestaciones neurológicas centrales y periféricas se asoció significativamente con la COVID-19 crítica (P valor= 0,011; OR: 2,005). El índice de mortalidad alcanzó 2,69 por ciento. Conclusiones: Las manifestaciones neurológicas en pacientes hospitalizados con la COVID-19 son muy frecuentes, y la COVID-19 crítica tiene mayor probabilidad de presentar manifestaciones neurológicas(AU)

Introduction: SARS-CoV-2 mainly affects the respiratory system, but the damage caused by this virus also extends to other systems, including the nervous system, and the mechanisms of neurological infection can be direct or indirect. Objective: To determine the relationship between neurological manifestations and disease severity in symptomatic COVID-19 positive patients at San Vicente de Paul Hospital in 2021. Material and Methods: A cross-sectional observational study was conducted using medical records of patients hospitalized with COVID-19 and neurological manifestations, which were classified into manifestations of the central nervous system and manifestations of the peripheral nervous system. Results: The results show that 74,1 percent of patients presented neurological manifestations; the highest percentage was concentrated in patients who developed severe disease (15 [60 percent], CNS; 91 [77,1 percent], PNS; 125 [65,4 percent], CNS and PNS). The joint presence of central and peripheral neurological manifestations was significantly associated with critical COVID-19 (P value= 0,011; OR: 2,005). The mortality rate reached 2,69 percent. Conclusions: Neurological manifestations in hospitalized COVID-19 patients are very common, and critical COVID-19 is more likely to have neurological manifestations(AU)

O Sistema de Saúde japonês e seus mecanismos de enfrentamento à COVID-19 / The Japanese Health System and its coping mechanisms against COVID-19

Introdução: apesar de ser o país de maior média de idade no mundo, o Japão tem se destacado no combate à pandemia da COVID-19 (do inglês Coronavirus Disease 2019) ao apresentar reduzidas taxas de contaminação pelo vírus e de mortalidade. Objetivo: discutir acerca das estratégias em saúde adotadas pelo Japão diante da pandemia da doença da COVID-19, bem como avaliar os dados sobre contaminação e mortalidade japoneses em comparação com os outros quatro países com maior média de idade do mundo (Itália, Alemanha, Portugal e Espanha) e o Brasil. Metodologia: para avaliação das estratégias em saúde japonesas foi realizada busca nas bases de dados: PubMed, Cochrane e Scielo, utilizando-se combinação dos termos "Japão", "covid", "coronavirus" e "sistemas de saúde", nos idiomas Inglês, Espanhol e Português. Os dados de infecção da COVID-19 foram extraídos do site Our World in Data, correspondendo ao período de 25 de janeiro de 2020 a 30 de julho de 2020. Resultados: dentre as medidas adotadas pelo país no enfrentamento à pandemia, destacam-se o diagnóstico e resposta precoces à infecção, o rastreamento de contatos, o diagnóstico precoce e disponibilidade de cuidados intensivos para pacientes graves e estímulo a medidas comportamentais de distanciamento. Dentre os países analisados, o Japão apresenta as menores taxas de contaminação e mortalidade em termos absolutos pela COVID-19. Conclusões: medidas de distanciamento social, diagnóstico e tratamento precoces parecem ter contribuído para o sucesso no combate à COVID-19 no Japão. No período estudado, em milhão de habitantes, o Japão teve 6,13 casos de Covid, enquanto o Brasil apresentou 218,26 casos. Já no número de mortes confirmadas pela doença, o primeiro teve uma taxa de 0,23 enquanto o segundo de 5,16 casos por milhão de habitantes. É possível, a partir do conhecimento dessas medidas, buscar mecanismos semelhantes ao traçar políticas de saúde no enfrentamento de pandemias em outros países (AU)

Introduction: despite being the country with the highest average age globally, Japan has stood out in the fight against the COVID-19 (Coronavirus Disease 2019) pandemic by presenting low contamination rates by the virus and mortality. Objective: we aim to discuss the health strategies adopted by Japan in the face of the COVID-19 disease pandemic, as well as to evaluate data on Japanese contamination and mortality compared to the other four countries with the highest average age in the world (Italy, Germany, Portugal and Spain) and Brazil. Methodology: the search was carried out to evaluate Japanese health strategies by using the following databases: PubMed, Cochrane, and Scielo using a combination of the terms "Japan", "covid", "coronavirus" and "health systems" in English, Spanish and Portuguese. The COVID-19 infection data was extracted from the Our World in Data website, from January 25, 2020, to July 30, 2020. Results: Among the measures adopted by the country to face the pandemic, the early diagnosis and response to infection, contact tracing, early diagnosis and availability of intensive care for critically ill patients, and encouraging behavioral distancing measures stand out. Among the countries analyzed, Japan has the lowest rates of contamination and mortality in absolute terms by COVID-19. Conclusions: social distancing measures, early diagnosis, and treatment seem to have contributed to the success in combating COVID-19 in Japan. In the studied period, in a million inhabitants, Japan had 6.13 cases of covid while Brazil had 218.26 cases. As for the number of deaths confirmed by the disease, the first had a rate of 0.23 while the second had 5.16 cases per million inhabitants. Based on the knowledge of these measures, it is possible to seek similar mechanisms when designing health policies to face pandemics in other countries (AU)

Estadísticas de mortalidad por covid 19: análisis de la calidad de la información sobre causas de fallecimiento / MORTALITY STATISTICS FOR COVID 19: ANALYSIS OF THE QUALITY OF THE INFORMATION ON CAUSES OF DEATH

El certificado médico de defunción (CMD) es la fuente de las estadísticas de causas de muerte en nuestro país. La falta de precisión de los datos que allí se registran afecta al análisis de las estadísticas de mortalidad y al diseño de políticas sanitarias basadas en dicho examen. La calidad de la información sobre causas de muerte se verá más o menos comprometida en la medida que el médico realice el registro de las causas de muerte acorde a los estándares establecidos por las autoridades sanitarias. La pandemia por COVID 19 ha resaltado la importancia de generar estadísticas confiables en salud, al mismo tiempo que la elaboración de esa información se ha visto afectada por diversos motivos. Se analizó la calidad del registro de causas de fallecimiento de pacientes con COVID 19 en el Hospital de Clínicas "José de San Martín". Se revisaron 488 certificados médicos de defunción (CMD) correspondientes a todos los fallecidos en el Hospital de Clínicas entre 13/04/2020 al 10/09/2020 (n: 373) y desde el 07/05/2021 al 08/06/2021 (n: 115). De todos ellos, 127 CMD informaban en al menos una de sus causas a la COVID 19 (códigos U.7 y siguientes del CIE 10). Hubo un 74,02% (n: 94) de causas de muerte "poco útiles" entre las causas inmediatas, 18,9% (n:24) entre las mediatas y 0% (n:0) en las originales. c) Se registró en forma completa el intervalo entre la enfermedad y la muerte en el 4,72% (n:6); y se registró la Causa Contribuyente (parte 2 del CMD) en un 11,02% (n: 14). La calidad de los registros de mortalidad por COVID 19 está comprometida. Se observó una alta proporción de "causas poco útiles" como registro en las causas de fallecimiento, y un déficit en el llenado del intervalo entre la enfermedad y la muerte, y en la causa contribuyente del fallecimiento. Debemos trabajar en todos los niveles para contribuir al mejoramiento de la certificación de las defunciones y por ende, a la obtención de estadísticas de mortalidad y de causas de muerte más precisas, que apoyen la evaluación de políticas públicas y la toma de decisiones acertadas en pro de la salud de la población.

The medical death certificate (CMD) is the source of the statistics of causes of death in our country. The lack of precision of the data recorded there affects the analysis of mortality statistics and the design of health policies based on said examination. The quality of the information on causes of death will be more or less compromised to the extent that the physician registers the causes of death in accordance with the standards established by the health authorities. The COVID 19 pandemic has highlighted the importance of generating reliable health statistics, at the same time that the preparation of this information has been affected for various reasons. The quality of the registry of causes of death of patients with COVID 19 at the Hospital de Clínicas "José de San Martín" was analyzed. We reviewed 488 medical death certificates (CMD) corresponding to all those who died at the Hospital de Clínicas between 04/13/2020 and 09/10/2020 (n: 373) and from 05/07/2021 to 06/08/ 2021 (no.: 115). Of all of them, 127 CMDs reported COVID 19 in at least one of their causes (ICD 10 codes U.7 and following). There were 74.02% (n: 94) of "not very useful" causes of death among the immediate causes, 18.9% (n: 24) among the mediate ones, and 0% (n: 0) in the original ones. c) The interval between illness and death was fully recorded in 4.72% (n:6); and the Contributing Cause (part 2 of the CMD) was registered in 11.02% (n: 14). The quality of COVID 19 mortality records is compromised. A high proportion of "unhelpful causes" was observed as a registry in the causes of death, and a deficit in filling the interval between illness and death, and in the contributing cause of death. We must work at all levels to contribute to improving the certification of deaths and, therefore, to obtaining more accurate mortality statistics and causes of death, which support the evaluation of public policies and the making of sound decisions in favor of the population health.

Desenlace fatal en embarazadas contagiadas con la COVID-19 / Fatal outcome wiht pregnant and COVID-19

Introducción: Múltiples han sido las muertes y contagios por el nuevo coronavirus. En medio de este contexto el contagio de la enfermedad en pacientes embarazadas ha sido bien documentado. Objetivo: Presentar los eventos ocurridos en embarazadas para transmitir la experiencia a quienes tratan estas pacientes. Presentación del caso: Se expone el caso de una gestante de 24 años, obesa, con embarazo de 25 semanas. Fue ingresada con neumonía por COVID-19 y evolución hacia la insuficiencia respiratoria grave que fallece durante la cesárea. Se recibió en el quirófano con hipoxemia e hipercapnia, taquicardia, cianosis, oliguria y ventilada a presión positiva con oxígeno al 100 %. Se conduce con ketamina, fentanilo y rocuronio. A los 35 min, y posterior a la histerotomía, presentó bradicardia progresiva, por lo que se inicia compresiones torácicas externas y tratamiento farmacológico. Se recuperó el ritmo sinusal a los 12 min, pero recidiva la parada en asistolia a los 20 min, con cianosis en esclavina. Se implementó compresiones y administración de epinefrina hasta fallecer 30 min después por no recuperación de ritmo y signos ciertos de la muerte. Conclusiones: La atención multidisciplinaria mejora las condiciones de tratamiento en todas las etapas. El manejo anestésico individualizado ofrece una estrategia invaluable en casos como estos, independientemente del resultado. El tromboembolismo pulmonar en la gestante es un riesgo latente y asociado a la COVID-19, incrementa, exponencialmente, su letalidad.

Introduction: Multiple deaths and infections due to the new coronavirus have occurred. In the midst of this context, the spread of the disease in pregnant patients has been well documented. Objective: Present the events that occurred in pregnant women, in order to share the experience with those who treat these patients. Presentation of the case: The case of a 24-year-old pregnant woman, obese, with a pregnancy of 25 weeks is presented. She was admitted with COVID-19 pneumonia and evolution towards severe respiratory failure led to her death during cesarean section. She was received in the operating room with hypoxemia and hypercapnia, tachycardia, cyanosis, oliguria and ventilated at positive pressure with 100% oxygen. She was treated with ketamine, fentanyl and rocuronium. At 35 min, and after hysterotomy, she presented progressive bradycardia, so external chest compressions and pharmacological treatment were initiated. The sinus rhythm was recovered at 12 min, but the asystole stop relapsed at 20 min, with cyanosis. Compressions and administration of epinephrine were implemented until death 30 minutes later due to non-recovery of rhythm and certain signs of death. Conclusions: Multidisciplinary care improves treatment conditions at all stages. Individualized anesthetic management offers an invaluable strategy in cases like these, regardless of the outcome. Pulmonary thromboembolism in pregnant women is a latent risk associated with COVID-19, exponentially increasing its lethality.

Hematological changes in SARS-COV-2 positive patients

Abstract Introduction The novel SARS-CoV-2 infection has been spreading around the world since January 2020 causing the Corona Virus Disease 2019. Leukopenia, lymphopenia and hypercoagulability with elevated D- Dimers have been described in COVID-19 patients to date. This study aimed to clarify if some blood parameters can be used as biomarkers to facilitate diagnosis and establish prognosis. Methods: We selected patients who had tested positive for SARS-CoV-2 and had had a hemogram performed between the March 15 and April 15, 2020. Socio-demographic and analytical data were obtained from 274 patients at admission in two Portuguese public hospitals. We then analyzed the hemogram parameters at admission in the intensive care and collected data on patient survival during the SARS-CoV-2 disease follow-up. The data were analyzed using appropriate statistical tests. Results: Patients requiring the intensive care unit (ICU) present an increase in leukocytes and neutrophils (+3.1 × 109/L and +6.4 × 109/L, respectively), a lymphocyte decrease and a platelet rise (-1.6 × 109/L and +60.8 × 109/L, respectively). The erythrocytes, hemoglobin and median globular volume tend to decrease (-0.5 × 1012, - 1.2 g/dL; -3 fL, respectively). The lactic acid dehydrogenase (LDH) at admission was significantly higher (+58.1 U/L). The age, sex, platelets, lymphocyte count neutrophil counts, neutrophil/lymphocyte ratio, erythrocytes and cell hemoglobin concentration mean (CHCM) are independently associated with mortality (odds ratio (OR) = 0.046, p < 0.001; OR = 0.2364, p= 0.045; OR = 9.106, p= 0.001; OR = 0.194, p= 0.033; OR = 0.062, p= 0.003; OR = 0.098, p= 0.002; OR = 9.021, p < 0.001; OR = 7.016, p= 0.007, respectively). Conclusion The hematological data at admission in the health care system can predict the mortality of the SARS-CoV-2 infection and we recommend its use in the clinical decisions and patient prognosis evaluation.

Dysregulation in erythrocyte dynamics caused by SARS-CoV-2 infection: possible role in shuffling the homeostatic puzzle during COVID-19

Abstract Introduction The evolving COVID-19 pandemic became a hallmark in human history, not only by changing lifestyles, but also by enriching scientific knowledge on viral infection and its consequences. Objective Although the management of cardiorespiratory changes is pivotal to a favorable prognosis during severe clinical findings, dysregulation of other systems caused by SARS-CoV-2 infection may imbalance erythrocyte dynamics, such as a bidirectional positive feedback loop pathophysiology. Method and Results Recent evidence shows that SARS-CoV-2 is capable of affecting the genetics and dynamics of erythrocytes and this coexists with a non-homeostatic function of cardiovascular, respiratory and renal systems during COVID-19. In hypothesis, SARS-CoV-2-induced systematical alterations of erythrocytes dynamics would constitute a setpoint for COVID-19-related multiple organ failure syndrome and death. Conclusion The present review covers the most frequent erythrocyte-related non-homeostatic findings during COVID-19 capable of providing mechanistic clues of SARS-CoV-2-induced infection and inspiring therapeutic-oriented scientific evidence.

Risk factors and spatial distribution associated with deaths due to COVID-19: an integrative review / Fatores de risco e distribuição espacial associados aos óbitos por COVID-19: uma revisão integrative / Factores de riesgo y distribución espacial asociados a las muertes por COVID-19: una revisión integradora

Background and objectives: understanding the clinical-epidemiological and environmental factors related to deaths due to COVID-19 and their distribution in space can serve as subsidies to direct and implement more effective health actions for vulnerable populations. Thus, the objective was to synthesize the scientific evidence related to risk factors and spatial distribution of deaths due to COVID-19 in the world. Content: this is an integrative literature review, and the following guiding question emerged: what is the scientific evidence related to risk factors and spatial distribution of deaths due to COVID-19 in the world? Searches were carried out in the Scientific Electronic Library Online (SciELO) and the Scopus, Web of Science and National Library of Medicine (PubMed) databases in June 2021. Original studies in Portuguese, English or Spanish, without time frame, excluding studies with a specific age group or with an audience with specific comorbidity, were used. A total of 25 studies were included, with findings in different scenarios around the world. Factors such as age, sex, pre-existing diseases were associated with deaths due to COVID-19, which had a heterogeneous spatial distribution and occurred in environmental, socioeconomic and geographic conditions peculiar to these territories. Conclusion: age equal to or greater than 60 years, males, cardiovascular diseases, diabetes mellitus and geographic areas with greater environmental pollution, greater population density and precarious sanitary conditions influenced the mortality of COVID-19.(AU)
