On May 20, 2012, at 02:03 UTC, a magnitude Ml 5.9 earthquake hit part of the Po Plain area (latitude, 44.89 ˚N; longitude, 11.23 ˚E) close to the village of Finale-Emilia in the Emilia-Romagna region (northern Italy). This caused a number of human losses and significant economic damage to buildings, and to local farms and industry. This earthquake was preceded by an increase in the seismicity the day before, with the largest shock of Ml 4.1 at 23:13 UTC (latitude, 44.90 ˚N; longitude, 11.26 ˚E). It was then followed by six other Ml 5.0 or greater events in the following weeks. The largest of these six earthquakes occurred on May 29, 2012, at 07:00 UTC (Ml 5.8), and was located 12 km southwest of the May 20, 2012, main event (latitude, 44.85 ˚N; longitude, 11.09 ˚E), resulting in the collapse of many buildings that had already been weakened, a greater number of victims, and most of the economic damage (see Figure 1). This sequence took place in one of the Italian regions that is considered to be at small-to-moderate seismic hazard [Gruppo di Lavoro MPS 2004]. Earthquakes of the M6 class have occurred in the past in this zone [Gruppo di Lavoro CPTI 2004], but with a much smaller time frequency with respect to the most seismically hazardous parts of Italy.

On 20 May 2012, a M5.9 earthquake hit the Emilia-Romagna region in northern Italy. Although it was of moderate magnitude, the quake affected an area up to 17 km from the epicenter, with severe damage and the collapse of several warehouses. Widespread liquefaction phenomena, such as sand boils and ground failures, were observed. Presented herein are the outcomes of a geotechnical post-earthquake reconnaissance survey conducted a week after the main shock in Sant'Agostino, a municipality near Ferrara, which was severely affected by the ground shaking. The presented findings add new liquefaction case records induced by a moderate earthquake in the Italian historical database. Non-invasive, seismic geophysical tests were carried out at four sites in the area of Sant'Agostino during the post-earthquake reconnaissance survey for near-surface geotechnical characterization. Preliminary assessment of liquefaction susceptibility has been carried out using post-earthquake field measurements at the four sites. Predictions based on standard, state of the practice empirical correlations are consistent with the observed liquefaction phenomena.

Bovine Abortion

Abstract Background Neospora caninum, a coccidian protozoan, represents an important cause of bovine abortion. Available N. caninum strains show considerable variation in vitro and in vivo, including different virulence in cattle. To which extent sexual recombination, which is possible in the intestines of domestic dogs and closely related carnivores as definitive hosts, contributes to this variation is not clear yet. Methods Aborted bovine foetuses were collected between 2015 and early 2019 from Italian Holstein Friesian dairy herds suffering from reproductive problems. A total of 198 samples were collected from 165 intensive farms located in Lombardy, northern Italy. N. caninum samples were subjected to multilocus-microsatellite genotyping using ten previously established microsatellite markers. In addition to our own data, those from a recent study providing data on five markers from other northern Italian regions were included and analysed. Results Of the 55 samples finally subjected to genotyping, 35 were typed at all or 9 out of 10 loci and their individual multilocus-microsatellite genotype (MLMG) determined. Linear regression revealed a statistically significant association between the spatial distance of the sampling sites with the genetic distance of N. caninum MLMGs (P < 0.001). Including data from this and a previous North Italian study into eBURST analysis revealed that several of N. caninum MLMGs from northern Italy separate into four groups; most of the samples from Lombardy clustered in one of these groups. Principle component analysis revealed similar clusters and confirmed MLMG groups identified by eBURST. Variations observed between MLMGs were not equally distributed over all loci, but predominantly observed in MS7, MS6A, or MS10. Conclusions Our findings confirm the concept of local N. caninum subpopulations. The geographic distance of sampling was associated with the genetic distance as determined by microsatellite typing. Results suggest that multi-parental recombination in N. caninum is a rare event, but does not exclude uniparental mating. More comprehensive studies on microsatellites in N. caninum and related species like Toxoplasma gondii should be undertaken, not only to improve genotyping capabilities, but also to understand possible functions of these regions in the genomes of these parasites.

The Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) pandemic had a significant impact on the Italian healthcare system, although geographical differences were present; regions in northern Italy have been the most severely affected while regions in the south of the country were relatively spared. Otolaryngologists were actively involved in the management of the pandemic. In this work, we analyzed and compared the otolaryngology surgical activity performed during the pandemic in two large public hospitals located in different Italian regions. In northern Italy, otolaryngologists were mainly involved in performing surgical tracheotomies in COVID-19 positive patients and contributed to the management of these patients in intensive care units. In central Italy, where the burden of the infection was significantly lower, otolaryngologists focused on diagnosis and treatment of emergency and oncology patients. This analysis confirms the important role of the otolaryngology specialists during the pandemic, but also highlights specific differences between two large hospitals in different Italian regions.

The diving bell spider <em>Argyroneta aquatica</em> is the only known spider to conduct a wholly aquatic life. For this reason, it has been the object of an array of studies concerning different aspects of its peculiar biology such as reproductive behavior and sexual dimorphism, physiology, genetic and silk. On the other hand, besides some empirical observations, the autoecology of this spider is widely understudied. We conducted an ecological study in a resurgence located in the Po Plain (Northern Italy, Province of Vercelli) hosting a relatively rich population of <em>Argyroneta</em> <em>aquatica</em>, aiming at identifying the ecological factors driving its presence at the micro-habitat level. By means of a specific sampling methodology, we acquired distributional data of the spiders in the study area and monitored physical-chemical and habitat structure parameters at each plot. We analyzed the data through Bernoulli Generalized Linear Models (GLM). Results pointed out a significant positive effect of the presence of aquatic vegetation in the plot. In addition, the presence of <em>A. aquatica</em> was significantly associated with areas of the resurgence characterized at the same time by high prey availability and low density of predators. Considering the ecological importance and rarity of this species, we update and revise the data on the distribution of <em>A. aquatica</em> in Italy.
