L’uso di video tutorial nella formazione di assistenti familiari a domicilio
Il presente contributo descrive un’esperienza di progettazione e realizzazione di video tutorial a supporto dell’apprendimento di assistenti familiari e di persone assistite a domicilio e per l’acquisizione di abilità assistenziali. Il progetto è scaturito da alcune criticità riscontrate da infermieri delle Cure Domiciliari nei percorsi formativi indirizzati agli assistenti domiciliari riconducibili a barriere culturali e linguistiche, esiguità di risorse e aspetti relazionali. I video sono stati organizzati in sequenze, sottotitolati in spagnolo e romeno e composti da immagini statiche, filmati, commenti audio e testi scritti. La sperimentazione ha evidenziato un riscontro positivo sia dei materiali realizzati sia dell’impatto nei percorsi di apprendimento
La didattica aumentata digitalmente: studio qualitativo sulla percezione di infermieri e ostetriche del corso di Laurea magistrale durante la pandemia SARS-CoV-2 in Italia
Background. The SARS-CoV-2 pandemic has necessitated a rapid transition to digitally augmented education, generating a phenomenon that is unprecedented in the history of university education of healthcare professionals. The purpose of this study is to understand the effects of online teaching on the learning of students of the Master's Degree, to collect the significant elements of their experience and stimulate reflection on teaching practices.
Objective. To describe perceptions and experiences of nurses and midwives in the Master's degree on digitally augmented learning during the SARS-CoV-2 pandemic. Method. A descriptive qualitative study was performed on a proactive sample of 34 nurse practitioners, pediatric nurses and midwives. The data was collected in January-February 2021 through an online form, built ad hoc. The answers were analyzed with deductive content analysis.
Results. 4 main categories emerge from the analysis of the texts: educational impact, time management, disadvantages of online teaching, distance learning-teaching. The results partly confirm what is reported in the literature about virtual learning, with better time management and the usefulness of video recordings. However, learning is strongly conditioned by the difficulties of interaction and communication between the students and between the teachers and the students.
Conclusion. The digitally augmented learning allowed the continuation of the training course of health professionals engaged during the SARS-CoV-2 emergency. However, distance learning if used exclusively for a long time is a limited tool as it modifies the didactic processes preventing the development of meaningful relationships, dialogue and educational relationships which are important and essential outcomes in the master's course.

La pandemia da SARS-CoV-2 ha reso necessaria una rapida transizione alla didattica aumentata digitalmente, generando un fenomeno che non vede precedenti nella storia della formazione universitaria dei professionisti sanitari. La finalità del presente studio è di comprendere gli effetti della didattica online sugli apprendimenti degli studenti del corso di Laurea magistrale per raccogliere gli elementi significativi della loro esperienza e stimolare la riflessione sulle pratiche didattiche.
Obiettivo. Descrivere le percezioni e i vissuti dei professionisti in formazione magistrale circa la didattica aumentata digitalmente durante la pandemia da SARS-CoV-2.
Metodi. È stato condotto uno studio qualitativo descrittivo su un campione propositivo di 34 professionisti infermieri, infermieri pediatrici e ostetriche. I dati sono stati raccolti nel periodo gennaio-febbraio 2021 attraverso un modulo online, costruito ad hoc. Le risposte sono state analizzate con la content analysis deduttiva.
Risultati. Dall’analisi dei testi emergono 4 categorie principali: impatto educativo, gestione del tempo, svantaggi della didattica online, apprendimento-insegnamento a distanza. I risultati confermano quanto riportato in letteratura, una migliore gestione del tempo e l’utilità delle videoregistrazioni. L’apprendimento è però fortemente condizionato dalle difficoltà di interazione e di comunicazione tra studenti e tra docenti e studenti.
Conclusioni. La didattica aumentata digitalmente ha consentito di continuare il percorso formativo dei professionisti sanitari impegnati durante l’emergenza da SARS-CoV-2. Tuttavia, la formazione a distanza se utilizzata per lungo tempo in modo esclusivo è uno strumento limitato poichè modifica i processi didattici impedendo di sviluppare relazioni significative, il dialogo e la relazione educativa che nel percorso magistrale sono importanti e imprescindibili outcomes.

Field clinical study evaluating the efficacy and safety of an oral formulation containing milbemycin oxime/praziquantel (Milbemax®, Novartis Animal Health) in the chemoprevention of the zoonotic canine infection by Dirofilaria repens
Dirofilaria repens is the causative agent of subcutaneous dirofilariosis of dogs, other animals and humans. This nematode is transmitted by mosquitoes of Aedes, Anopheles and Culex genera. In dogs, the parasite may cause subclinical infection or cutaneous signs. Recently, D. repens has emerged and spread in different geographical areas, with an increase of cases in dogs and humans. Chemoprevention in dogs in endemic areas is the most reliable approach for controlling this infection. This paper describes a randomized, blocked and multicentric clinical field study investigating the efficacy of an oral, chewable formulation containing milbemycin oxime/praziquantel (Milbemax®, Novartis Animal Health) in the chemoprevention of subcutaneous dirofilariosis in dogs.
METHODS:
This study was conducted in endemic areas of Italy. A total of 249 dogs, at two sites, negative for D. repens, were allocated into two groups (i.e. Treated -T1 vs Untreated-T2) with a ratio of 1:1, and subjected to clinical visits and blood sampling once monthly until the end of the study. All blood samples were microscopically and genetically examined. Animals belonging to T1 group received a minimum target dose of 0.5 mg/kg bodyweight of milbemycin oxime and 5 mg/kg of praziquantel in commercial tablets (Milbemax®) according body weight once every 4 weeks. Animals of group T2 were not treated with Milbemax® but received, when necessary, specific parasiticide treatments. The study duration was 336 ± 2 days for each dog.
RESULTS:
A total of 219 dogs completed the study (i.e. 111 in T1 and 108 in T2), while 30 dogs (i.e. 13 in T1, 17 in T2) were withdrawn for a variety of reasons unrelated to administration of Milbemax®. The percentages of animals not showing microfilariae of D. repens were 100% (111 animals) in T1 and 94.7% (108 animals out of 114) in group T2. Milbemax® was shown to be safe in treated dogs.
CONCLUSIONS:
The results of this study confirm that the monthly use of Milbemax® in dogs is effective and safe for the prevention of subcutaneous dirofilariosis in endemic areas
Ecological impacts of atmospheric pollution and interactions with climate change in terrestrial ecosystems of the Mediterranean Basin:Current research and future directions
Mediterranean Basin ecosystems, their unique biodiversity, and the key services they provide are currently at risk due to air pollution and climate change, yet only a limited number of isolated and geographically-restricted studies have addressed this topic, often with contrasting results. Particularities of air pollution in this region include high O3 levels due to high air temperatures and solar radiation, the stability of air masses, and dominance of dry over wet nitrogen deposition. Moreover, the unique abiotic and biotic factors (e.g., climate, vegetation type, relevance of Saharan dust inputs) modulating the response of Mediterranean ecosystems at various spatiotemporal scales make it difficult to understand, and thus predict, the consequences of human activities that cause air pollution in the Mediterranean Basin. Therefore, there is an urgent need to implement coordinated research and experimental platforms along with wider environmental monitoring networks in the region. In particular, a robust deposition monitoring network in conjunction with modelling estimates is crucial, possibly including a set of common biomonitors (ideally cryptogams, an important component of the Mediterranean vegetation), to help refine pollutant deposition maps. Additionally, increased attention must be paid to functional diversity measures in future air pollution and climate change studies to establish the necessary link between biodiversity and the provision of ecosystem services in Mediterranean ecosystems. Through a coordinated effort, the Mediterranean scientific community can fill the above-mentioned gaps and reach a greater understanding of the mechanisms underlying the combined effects of air pollution and climate change in the Mediterranean Basin

ECLAIRE: Effects of Climate Change on Air Pollution Impacts and Response Strategies for European Ecosystems. Project final report
The central goal of ECLAIRE is to assess how climate change will alter the extent to which air pollutants threaten terrestrial ecosystems. Particular attention has been given to nitrogen compounds, especially nitrogen oxides (NOx) and ammonia (NH3), as well as Biogenic Volatile Organic Compounds (BVOCs) in relation to tropospheric ozone (O3) formation, including their interactions with aerosol components. ECLAIRE has combined a broad program of field and laboratory experimentation and modelling of pollution fluxes and ecosystem impacts, advancing both mechanistic understanding and providing support to European policy makers.
The central finding of ECLAIRE is that future climate change is expected to worsen the threat of air pollutants on Europe’s ecosystems.
Firstly, climate warming is expected to increase the emissions of many trace gases, such as agricultural NH3, the soil component of NOx emissions and key BVOCs. Experimental data and numerical models show how these effects will tend to increase atmospheric N deposition in future. By contrast, the net effect on tropospheric O3 is less clear. This is because parallel increases in atmospheric CO2 concentrations will offset the temperature-driven increase for some BVOCs, such as isoprene. By contrast, there is currently insufficient evidence to be confident that CO2 will offset anticipated climate increases in monoterpene emissions.
Secondly, climate warming is found to be likely to increase the vulnerability of ecosystems towards air pollutant exposure or atmospheric deposition. Such effects may occur as a consequence of combined perturbation, as well as through specific interactions, such as between drought, O3, N and aerosol exposure.
These combined effects of climate change are expected to offset part of the benefit of current emissions control policies. Unless decisive mitigation actions are taken, it is anticipated that ongoing climate warming will increase agricultural and other biogenic emissions, posing a challenge for national emissions ceilings and air quality objectives related to nitrogen and ozone pollution. The O3 effects will be further worsened if progress is not made to curb increases in methane (CH4) emissions in the northern hemisphere.
Other key findings of ECLAIRE are that: 1) N deposition and O3 have adverse synergistic effects. Exposure to ambient O3 concentrations was shown to reduce the Nitrogen Use Efficiency of plants, both decreasing agricultural production and posing an increased risk of other forms of nitrogen pollution, such as nitrate leaching (NO3-) and the greenhouse gas nitrous oxide (N2O); 2) within-canopy dynamics for volatile aerosol can increase dry deposition and shorten atmospheric lifetimes; 3) ambient aerosol levels reduce the ability of plants to conserve water under drought conditions; 4) low-resolution mapping studies tend to underestimate the extent of local critical loads exceedance; 5) new dose-response functions can be used to improve the assessment of costs, including estimation of the value of damage due to air pollution effects on ecosystems, 6) scenarios can be constructed that combine technical mitigation measures with dietary change options (reducing livestock products in food down to recommended levels for health criteria), with the balance between the two strategies being a matter for future societal discussion. ECLAIRE has supported the revision process for the National Emissions Ceilings Directive and will continue to deliver scientific underpinning into the future for the UNECE Convention on Long-range Transboundary Air Pollution

The Messinian Salinity Crisis: New seismic evidence in the West-Sardinian Margin and Eastern Sardo-Provençal basin (West Mediterranean Sea)
We processed and interpreted a newly acquired geophysical dataset (WS10 project) integrated with vintage
seismic profiles to study the evolution of the Sardinian passive margin of the Sardo-Provençal basin. The most
prominent features of the area of study are a consequence of the Messinian Salinity Crisis (MSC) which produced
a thick salt layer in the deep basin. Complex halokinetic tectonics deformed the overlying Messinian Upper Unit
(UU) and the Pliocene–Quaternary (PQ) sediments, sometimes also bending the sea bottom. A thinner autochthonous
salt in the UU suggests at least one further low stand during the late MSC.
The Messinian Erosional Surface (MES) separates the erosional truncation of the pre-Messinian sedimentary sequence
from the overlaying Plio-Pleistocene sequence with a clear angular discordance, which almost completely
masks possible earlier erosional events. The MES is present across the middle and upper slopes of the Sardinian
margin and can be easily recognized down to the lower slope, where it interfingers with the Messinian evaporites
which gradually thicken basinward.
We propose a correlation between the main erosional surface of the lower slope and the salt layer recognized in
the UU as a consequence of a falling stage during the last part of the MSC.
The seismic profiles now available along the West Sardinian margin provide novel and crucial information to correlate
the Messinian depositional units in the deep basin with those present in the lower continental slope and with
the erosional surface of the middle and upper slopes. Our data and interpretation highlight the main units of the
Messinian trilogy and further internal sequences that are probable related to cyclic fluctuations during their
deposition
