ABSTRACT
Objective: From the onset of COVID-19 pandemic, the presence of previous cardiopathy was thought to be related with a worse prognosis of the disease. We aimed to analyse that theoretical adverse impact in a large cohort of patients. Method: We selected 1065 patients admitted for SARS-CoV-2 pneumonia between March and June 2020, divided in three groups according to (1) absence of cardiopathy, (2) presence of valvular heart disease or ischemic heart disease, or (3) presence of heart failure. We analysed the differences between groups regarding the need for admission in intensive care unit for mechanical ventilation or mortality during admission, or mortality during admission or in the next 6 months. Results: The factors that were associated with a worse prognosis both in acute phase and in the next 6 months were age, male gender, obesity and oncologic disease. The presence of previous cardiopathy did not have an adverse prognostic impact neither initially nor in the short term, in our study. Conclusions: We did not obtain significative association of the presence of cardiopathy with a worse medical evolution, neither in acute phase nor in the short term, of patients admitted for SARS-CoV-2 pneumonia.
Objetivo: Desde el inicio de la pandemia por enfermedad por coronavirus 2019 (COVID-19) se relacionó la presencia de cardiopatía previa con un peor pronóstico de la enfermedad. Nuestro objetivo fue analizar esa posible repercusión desfavorable en una cohorte amplia de pacientes. Método: Se incluyeron 1,065 pacientes ingresados con neumonía por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) entre marzo y junio de 2020, divididos en tres grupos, según no tuvieran cardiopatía previa (grupo 1), presentaran cardiopatía valvular o isquémica (grupo 2) o tuvieran insuficiencia cardiaca (grupo 3). Se analizaron las diferencias entre los grupos en cuanto a necesidad de ingreso en unidad de cuidados intensivos para ventilación mecánica o mortalidad durante el ingreso, o mortalidad durante el ingreso o a los seis meses. Resultados: Los factores que se asociaron con un peor pronóstico inicial y a los seis meses fueron la edad, el sexo masculino, la obesidad y la presencia de patología oncológica, sin que la presencia de cardiopatía supusiera una influencia pronóstica negativa inicial ni a corto plazo en nuestro trabajo. Conclusiones: No obtuvimos asociación significativa de la presencia de cardiopatía por si sola con una peor evolución en fase aguda ni a corto plazo de pacientes ingresados con neumonía por SARS-CoV-2.
ABSTRACT
The environmental knowledge of inhabitants residing in a highly biodiverse mountainous region of western Mexico with an important economic forestry sector was investigated. Indices of environmental knowledge, by average and through a factor analysis, were developed and characterized using survey data collected in 2018 and 2021. These indices showed high levels of correlation, and followed similar patterns of distributions. Ordinary least squares and quantile regressions were used to examine social, economic, demographic, and perceptions as determinant factors of the generated indices. Age and education were repeatedly found as important factors influencing environmental knowledge, while income and gender were consistently not significant factors. Furthermore, environmental knowledge was related to quality of life. The index developed by factor analysis generated more significantly stable parameter results across percentiles of environmental knowledge. The indices were recommended for monitoring environmental knowledge in long term studies.
