Estimation of the number of preventable COVID-19 deaths in relation to the restrictive measures adopted in Europe.

INTRODUCTION: In December 2019, a new coronavirus emerged in Wuhan, China, which has become a global health problem. OBJECTIVES: To estimate how many daily COVID-19 deaths per 100,000 population could have been avoided if each one of five restrictive measures had been implemented at the time the first case was diagnosed, and to estimate a multiple linear regression model predictive of the number of deaths per 100,000 population. METHODS: A simple linear regression was performed between the days elapsed since the first COVID-19 diagnosed case, implementation of each one of the five restrictive measures carried out by the 39 European studied countries, the number of hospital beds per 1,000 population (independent variables) and the number of COVID-19 deaths per 100,000 population. RESULTS: For each day elapsed from the first COVID-19 reported case to the adoption of restrictive measures, between 0.611 (p = 0.004) and 1.863 (p = 0.000) patients died per 100,000 population, depending on the implemented measure. CONCLUSIONS: Restrictive measures and social distancing, as well as promptness of their implementation, are necessary for achieving a decrease in COVID-19 infections and mortality.

INTRODUCCIÓN: En diciembre de 2019 surgió un nuevo coronavirus en Wuhan, China, que se ha convertido en un problema de salud global. OBJETIVO: Estimar cuántos fallecimientos diarios atribuibles a COVID-19 por cada 100 000 habitantes se podrían haber evitado si se hubiese llevado a cabo cada una de las cinco medidas restrictivas al momento del diagnóstico del primer caso, así como estimar un modelo de regresión lineal múltiple predictivo del número de fallecimientos por cada 100 000 habitantes. MÉTODOS: Se realizó un modelo de regresión lineal simple entre los días transcurridos desde el primer caso diagnosticado de COVID-19, la implantación de cada una de las cinco medidas llevadas a cabo por los 39 países europeos estudiados, el número de camas hospitalarias por 1000 habitantes (variables independientes) y el número de fallecimientos por COVID-19 por 100 000 habitantes. RESULTADOS: Por cada día transcurrido desde el primer caso notificado de COVID-19 hasta la adopción de las medidas restrictivas, fallecieron entre 0.611 (p = 0.004) y 1.863 (p = 0.000) pacientes por cada 100 000 habitantes, dependiendo de la medida implementada. CONCLUSIONES: Las medidas restrictivas y el distanciamiento social, así como la celeridad de su instauración, son necesarios para lograr el descenso del número de contagios de COVID-19 y su mortalidad.

Estimation of the number of preventable COVID-19 deaths in relation to the restrictive measures adopted in America.

INTRODUCTION: In America, the United States was particularly affected by the COVID-19 pandemic. OBJECTIVES: To estimate how many daily COVID-19 deaths per 100,000 population would have been avoided if each one of five restrictive measures had been implemented at the time of diagnosis and to estimate a multiple linear regression model predictive of the number of deaths per 100,000 population based on the measures adopted by the countries. METHODS: A simple linear regression was performed between the days elapsed since the first COVID-19 diagnosed case and the implementation of each one of the five restrictive measures by the 27 American countries studied and the number of COVID-19 deaths per 100,000 population. RESULTS: For each day between the first COVID-19 reported case and the adoption of restrictive measures, between 0.250 (p = 0.021) and 0.600 (p = 0.001) patients per 100,000 population died, depending on the measure in question. CONCLUSIONS: Adoption of restrictive measures and social distancing are necessary for reducing the number of people infected with COVID-19 and their mortality. In addition, promptness of their establishment is essential in order to reduce the number of deaths.

RESULTADOS: Por cada día entre el primer caso reportado de COVID-19 y la adopción de medidas restrictivas, fallecieron entre 0.250 (p = 0.021) y 0.600 (p = 0.001) pacientes por cada 100 000 habitantes, dependiendo de la medida en cuestión.

Obstructive sleep apnea knowledge and attitudes among recent medical graduates training in Ecuador.

BACKGROUND: We aimed to assess recent Latin American medical school graduates' knowledge and attitudes about OSA and examine whether their knowledge and attitudes about OSA differed from practicing physicians. METHODS: Recent medical graduates completed the Spanish translation of the OSA Knowledge and Attitudes (OSAKA) questionnaire at the 2013 national primary-care residency-placement meeting in Ecuador. The OSAKA includes 18 knowledge and five attitudinal items about OSA. We compared recent graduates' data with data collected in 2010-2011 from practicing physicians using chi-square tests of associations among categorical variables and analysis of variance of differences in mean knowledge and attitude scores. Unadjusted logistic regression models tested the odds that recent graduates (vs. practicing physicians) answered each item correctly. RESULTS: Of 265 recent graduates, 138 (52.1%) were male, and mean age was 25.9 years. Although mean knowledge was low overall, scores were lower for recent graduates than for the 367 practicing physicians (53.5% vs. 60.4%; p < 0.001). Practicing physicians were significantly more likely to answer specific items correctly with one exception-recent graduates were more likely to know that < 5 apneas-hypopneas/h is normal (OR 1.47, 1.03-2.07). Physicians in practice attributed greater importance to OSA as clinical disorder and the need for identifying patients with OSA; but recent graduates reported greater confidence in managing patients with OSA and CPAP. CONCLUSIONS: OSA-focused educational interventions during medical school should help to improve recent medical graduates' abilities to diagnose and treat OSA. We recommend a greater number of hours of medical students' exposure to sleep education.
