Background Aspergillosis is a serious infection, and in Spain, the influence of epidemiology and climate on the resulting expenses of aspergillosis is not well established. Aim A retrospective descriptive study using the Minimum Basic Data Set was performed on records of patients admitted to hospitals of the National Health System between 1997 and 2017 with a diagnosis of aspergillosis. The weather parameters were obtained from the State Agency of Meteorology from Spain. Results A total of 32,960 patients were identified, of whom 22,383 were men (68%). The mean age (±SD) was 61.1 ± 19.1 years. The mean incidence rate for all diagnoses was 3.54 cases per 100,000 person‐years (95% CI, 3.50–3.57). The incidence rate in men was twice as high as that in women, 4.89 (95% CI, 4.82–4.95) vs. 2.24 (95% CI, 2.19–2.27) cases per 100,000 person‐years (p > .001). The highest incidence rates were concentrated in northern Spain. One in four patients died (8,080 cases; 25%). There was a moderate positive linear association between rainfall and incidence rate (rP = .508; p = .026). In contrast, the Pearson's correlation coefficient indicated a moderate negative linear relationship between temperature and incidence rate (rP = −.447; p = .050). We observed a higher incidence in the months with higher humidity and rainfall. Conclusions Our study supports a high burden of aspergillosis in Spain, with an increase in cases in the past two decades. Additionally, the influence of climatological factors on the incidence of aspergillosis is highlighted. Despite preemptive treatment strategies, this infection still has a high mortality.

Background. The diagnosis of SARS-CoV-2 infection presents some limitations. RT-PCR in nasopharyngeal swabs is considered the gold standard for the diagnosis, although it can have false negative results. We aimed to analyze the accuracy of repeating nasopharyngeal swabs based on different clinical probabilities. Methods. Retrospective observational study of the first patients admitted to a two COVID Internal Medicine wards at the University Hospital Marqués de Valdecilla, Santander, from March to April 2020. RT-PCR targering E, N, RdRP and ORFab1 genes and antibody tests detecting IgG. Results. A total of 145 hospitalized patients with suspected SARS-Cov2 infection were admitted and in 98 (67.5%) diagnosis was confirmed. The independent predictive variables for SARS-CoV-2 infection were: epidemiological contact, clinical presentation as pneumonia, absence of pneumonia in the last year, onset of symptoms > 7 days, two or more of the following symptoms -dyspnea, cough or fever- and serum lactate dehydrogenase levels >350 U/L (p<0.05). A score based on these variables yielded an AUC-ROC of 0.89 (CI95%, 0.831-0.946; p<0.001). The accuracy of the first nasopharyngeal swabs was 54.9%. Repeating nasopharyngeal swabs two or three times allows to detect an additional 16% of positive cases. The overall accuracy of successive RT-PCR tests in patients with low pre-test probability was <5%. Conclusions. We have defined a pre-test probability score based on epidemiological and clinical data with a high accuracy for diagnosis of SARS-CoV-2. Repeating nasopharyngeal swabs avoids sampling errors, but only in medium of high probability pre-test clinical scenarios.

(1) Background: Aspergillus produces high morbidity and mortality, especially in at-risk populations. In Spain, the evolution of mortality in recent years due to this fungus is not well established. The aim of this study was to estimate the case fatality rate of aspergillosis in inpatients from 1997 to 2017 in Spain. (2) Methodology: A retrospective descriptive study was conducted with records of inpatients admitted to the National Health System with a diagnosis of aspergillosis. (3) Principal findings: Of 32,960 aspergillosis inpatients, 24.5% of deaths were registered, and 71% of the patients who died were men. The percentage of deaths increased progressively with age. The case fatality rate progressively decreased over the period, from 25.4 and 27.8% in 1997–1998 to values of 20.6 and 20.8% in 2016 and 2017. Influenza and pneumonia occurrence/association significantly increased case fatality rates in all cases. (4) Conclusions: Our study shows that lethality significantly decreased in the last two decades despite the increase in cases. This highlights the fact that patients with solid and/or hematological cancer do not have a much higher mortality rate than the group of patients with pneumonia or influenza alone, these two factors being the ones that cause the highest CFRs. We also need studies that analyze the causes of mortality to decrease it and studies that evaluate the impact of COVID-19.
