BackgroundMore intense tropical cyclones (TCs) are expected in the future under a warming climate scenario, but little is known about their mortality effect pattern across countries and over decades. We aim to evaluate the TC-specific mortality risks, periods of concern (POC) and characterize the spatiotemporal pattern and exposure-response (ER) relationships on a multicountry scale.Methods and findingsDaily all-cause, cardiovascular, and respiratory mortality among the general population were collected from 494 locations in 18 countries or territories during 1980 to 2019. Daily TC exposures were defined when the maximum sustained windspeed associated with a TC was ≥34 knots using a parametric wind field model at a 0.5° × 0.5° resolution. We first estimated the TC-specific mortality risks and POC using an advanced flexible statistical framework of mixed Poisson model, accounting for the population changes, natural variation, seasonal and day of the week effects. Then, a mixed meta-regression model was used to pool the TC-specific mortality risks to estimate the overall and country-specific ER relationships of TC characteristics (windspeed, rainfall, and year) with mortality. Overall, 47.7 million all-cause, 15.5 million cardiovascular, and 4.9 million respiratory deaths and 382 TCs were included in our analyses. An overall average POC of around 20 days was observed for TC-related all-cause and cardiopulmonary mortality, with relatively longer POC for the United States of America, Brazil, and Taiwan (>30 days). The TC-specific relative risks (RR) varied substantially, ranging from 1.04 to 1.42, 1.07 to 1.77, and 1.12 to 1.92 among the top 100 TCs with highest RRs for all-cause, cardiovascular, and respiratory mortality, respectively. At country level, relatively higher TC-related mortality risks were observed in Guatemala, Brazil, and New Zealand for all-cause, cardiovascular, and respiratory mortality, respectively. We found an overall monotonically increasing and approximately linear ER curve of TC-related maximum sustained windspeed and cumulative rainfall with mortality, with heterogeneous patterns across countries and regions. The TC-related mortality risks were generally decreasing from 1980 to 2019, especially for the Philippines, Taiwan, and the USA, whereas potentially increasing trends in TC-related all-cause and cardiovascular mortality risks were observed for Japan.ConclusionsThe TC mortality risks and POC varied greatly across TC events, locations, and countries. To minimize the TC-related health burdens, targeted strategies are particularly needed for different countries and regions, integrating epidemiological evidence on region-specific POC and ER curves that consider across-TC variability.

El presente estudio explora las actividades, los proyectos y las líneas de acción de veinticuatro medialabs de instituciones de educación superior elegidos a partir de un sistema no probabilístico. Sobre la muestra se aplica un análisis de contenido cualitativo para mapear las características de los laboratorios. Siguiendo un proceso inductivo de categorización, el estudio identifica como ejes de trabajo destacados iniciativas que materializan los principios de la inteligencia colectiva, impulsan la transformación de los sistemas de enseñanza y aprendizaje, y promueven el uso del lenguaje audiovisual y multimedia dentro y fuera del aula. Los resultados subrayan patrones de enseñanza que estrechan los vínculos de las instituciones con sus entornos sociales. Las iniciativas encontradas muestran de qué manera los medialabs facilitan nuevas formas de alcanzar el conocimiento en áreas tan variadas como el arte, el diseño, el periodismo o la ingeniería a través del uso de la tecnología.

The transmission of coronaviruses can be affected by several factors, including the climate. Due to the rapid spread of COVID-19 and the urgent need for rapid responses to contain the pandemic, it is essential to understand the role that weather conditions on the transmission of SARS-CoV-2. We evaluate the influence of meteorological factors on the incidence of COVID-19 during the first wave of the epidemic in Catalonia. We conducted a geographical analysis at the county level to evaluate the association between mean temperature, absolute humidity, solar radiation, and the cumulative incidence of COVID-19. Next, we used a time-series design to assess the short-term effects of meteorological factors on the daily incidence of COVID-19. We found a geographical association between meteorological factors and the cumulative incidence of COVID-19, from the end of March to June 2020, and a lesser extent in the short-term on the daily incidence during the first wave of the epidemic in Spain. Our findings suggest that warm and wet climates may reduce the incidence of COVID-19 in Catalonia. However, policy makers must interpret with caution any COVID-19 risk predictions based on climate information alone.

Muchos de los comentaristas de Gómez Dávila han notado que el carácter de su obra es intertextual, es decir, que no es un sistema cerrado: siempre está conectado implícitamente con otros libros y pensadores. El mismo Gómez Dávila nos indica en sus Escolios que Montaigne y Burckhardt tienen un rol central en esta intertextualidad. El siguiente artículo se propone interpretar la conexión entre los dos pensadores mencionados y la obra del colombiano. En el caso de Burckhardt, se mostrará cómo su pesimismo antropológico basado en una idea del pecado original, su escepticismo sobre la posibilidad humana de construir utopías, su negación de la idea de progreso y su concepción del tamaño y el papel del Estado aparecen y se desarrollan en el pensamiento del colombiano. En el caso de Montaigne, se mostrará su cercanía con Gómez Dávila a partir de sus similitudes biográficas, su alejamiento del espíritu académico de sus propios tiempos, su concepción de la filosofía, su escepticismo como arma para defender la fe y su fuerte conservatismo. Finalmente, se concluirá que esta intertextualidad que el autor mismo señala en su confesión sobre Montaigne y Burckhardt nos ayuda a darle orden y sentido a sus posiciones políticas en los Escolios. En efecto, se intentará mostrar que Gómez Dávila articula las influencias de sus maestros para concluir en una visión de mundo reaccionaria.
