Did anomalous atmospheric circulation favor the spread of COVID-19 in Europe?

The current pandemic of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is having negative health, social and economic consequences worldwide. In Europe, the pandemic started to develop strongly at the end of February and beginning of March 2020. Subsequently, it spread over the continent, with special virulence in northern Italy and inland Spain. In this study we show that an unusual persistent anticyclonic situation prevailing in southwestern Europe during February 2020 (i.e. anomalously strong positive phase of the North Atlantic and Arctic Oscillations) could have resulted in favorable conditions, e.g., in terms of air temperature and humidity among other factors, in Italy and Spain for a quicker spread of the virus compared with the rest of the European countries. It seems plausible that the strong atmospheric stability and associated dry conditions that dominated in these regions may have favored the virus propagation, both outdoors and especially indoors, by short-range droplet and aerosol (airborne) transmission, or/and by changing social contact patterns. Later recent atmospheric circulation conditions in Europe (July 2020) and the U.S. (October 2020) seem to support our hypothesis, although further research is needed in order to evaluate other confounding variables. Interestingly, the atmospheric conditions during the Spanish flu pandemic in 1918 seem to have resembled at some stage with the current COVID-19 pandemic.

[Efficiency of minor surgery in primary care according to the costs]. / Eficiencia de la cirugía menor en atención primaria según el nivel de facturación.

AIM: To quantify the cost of minor surgery in our health district during a year, by examining the amounts charged. To find the degree of clinical/pathological correlation and the number of complications, as indirect indicators of quality. DESIGN: Descriptive, cross-sectional, retrospective study. SETTING: Primary care, Río Nacimiento Health District, Abla (Almería). PARTICIPANTS: The study included all those patients attended within the minor surgery programme in the year 2000, and all the procedures used (84 patients and 95 procedures). MAIN MEASUREMENTS: The variables analysed were: type of procedure and surgery, clinical/pathological correlation, early surgical complications, and cost per procedure. We calculated the cost of our activity on the basis of: a) cost occasioned at the health centre; b) what a medical insurance company would bill; c) what a primary care district would bill, and d) what a health service hospital would bill. RESULTS: 95 procedures in 84 patients were examined. 31 samples were sent to pathology with a clinical-pathological correlation of 77.42%. No complications were recorded. At our centre the cost was 817.18 euros. An insurance company would have charged 8803.63 euros; a PC district, 4852.03 euros; and a health service hospital, 14 015.39 euros. CONCLUSION: The minor surgery performed at our health centre by our team was more cost-effective than if it was performed in other public or private centres with high standards of quality.
