Soddisfazione degli infermieri: un'analisi basata sulle evidenze
No full textPer analizzare la soddisfazione degli infermieri in Italia abbiamo condotto una scoping review,
o revisione esplorativa. Questa metodologia è stata scelta per fornire una mappatura
esaustiva della letteratura esistente sui temi della soddisfazione lavorativa, della motivazione,
dell’intenzione di lasciare il lavoro e dell’empowerment tra gli infermieri italiani, identificando
le lacune di ricerca e sintetizzando le evidenze attuali.
La raccolta delle evidenze si è basata sugli studi pubblicati fra il 2020 e 2024 su riveste referate
attraverso la banca dati Scopus. A questi studi sono stati aggiunti altri studi individuati
dagli esperti in management sanitario, e ritenuti rilevanti da rappresentanti FNOPI, sia per
l’ampiezza del campione che per la rilevanza dello studio.
I criteri di individuazione degli studi da letteratura sono stati i seguenti:
• Ambito geografico: Studi condotti in Italia o che includono infermieri che lavorano in
Italia (l’obiettivo è quello di avere evidenze sulla situazione italiana).
• Tipo di pubblicazione: Articoli di ricerca originali pubblicati in riviste peer-review
(sono esclusi editoriali o lettere alle riviste per includere solo evidenze recenti derivanti da
studi descritti nell’articolo).
• Periodo di pubblicazione: Studi pubblicati tra il 2020 e il 2024 (per limitare gli studi
ai dati più recenti, a cui si sono aggiunti articoli, paper e capitoli segnalati da esperti o rappresentanti
FNOPI)
• Popolazione: Infermieri impiegati in strutture sanitarie italiane
• Lingua: Articoli in inglese o italiano.
• Temi: Studi che trattano la soddisfazione lavorativa, la motivazione, l’intenzione di
lasciare il lavoro o la ritenzione degli infermieri che riportino evidenze quantitative.
La revisione integrata da ulteriori studi offre una panoramica sui livelli di soddisfazione e
intenzione di cambiare lavoro. Collateralmente alle informazioni quantitative vengono riportate
le sintesi sui fattori indagati negli studi che influenzano la soddisfazione lavorativa e il
benessere degli infermieri.
Le analisi qui riportate sono esplorative e hanno l’obiettivo di fornire una prima panoramica
di quanto risulta dai dati pubblicati che riguardano le condizioni di lavoro degli infermieri in
Italia. Di 19 studi
Po-210 and Pb-210 in sulphur fumarolic incrustations from Vulcano Island (Sicily, Italy)
No full textTh-230 dating of the speleothems from the "Grotta del Fiume - Grotta Grande del Vento" Karst system in Frasassi (An) and paleoenvironmental implications
No full textChronological measurements have been carried out on speleothems from the Grotta del Fiume-Grotta Grande del Vento karst system in Frasassi (Ancona, Italy) by means of the 230Th radiometric method in order to date hypogean karst levels and related geological events. Higher levels were found to be older than the lower ones according to standstills and sinkings of the water table. The dated speleothems from the first and second level formed less than 10,000 years ago; the minimum ages of the third and fifth levels, which are respectively 130,000 and 200,000 years old, were correlated to climatic events. Dating different portions of a speleothem allows the measurements of the radial and vertical accretion rates and their variation over time. Such data together with the 234U/238U activity ratio and the uranium content of the speleothems have been correlated with the climatic variations connected to the glacial cycles. The same data have been used to fit a hydrogeological model
Helix breakage during left bundle pacing area implantation
No full textA left bundle pacing stimulation pacemaker was implanted using stylet driver lead. The screw incarceration occurred after positioning of the lead. The screw rupture occurred during lead retraction; the distal portion of the screw remained incarcerated at the interventricular septum. © 2024 Wiley Periodicals LLC

Maars to calderas: end-members on a spectrum of explosive volcanic depressions
by Palladino, D. M., Valentine, G. A., Sottili, G., and Taddeucci, J. (2015). Front. Earth Sci. 3:36.
doi: 10.3389/feart.2015.00036
Reason for Corrigendum:
In the original article (Palladino et al., 2015), there was an error in Figure 1. The vertical axis
of the qualitative plot reported erroneously “ratio of juvenile to lithic materials in deposits outside
of depression”. The correct wording is as follows: “ratio of juvenile to total (i.e., juvenile+lithic)
materials in deposits outside of depression”. In fact, as it was reported correctly in the text, the
amount of juvenilematerial (i.e., scoria or pumice) deposited ouside the different types of explosive
volcanic depressions increases from zero (i.e., no juvenile, all lithic products), as is the case of
hydrothermal (phreatic) explosion craters, to become largely dominant over the lithic component
in the case of ash flow deposits associated with large overpressure collapse calderas. The corrected Figure 1 appears below. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way

Uranium Series Disequilibrium Dating in volcanic areas
No full textDisequilibrium existing within the uranium series radioactive family (the so called ‘U-Th’ or ‘230Th’ method) can be used for chronological purposes in volcanic areas. It can be applied to volcanic rocks as well as to travertines connected to volcanic events, provided that the age of these materials (volcanics or travertines) is younger than ∼300 ka. Many problems, capable of seriously affecting the reliability of the method, arise. This paper is intended for people who deal with chronology in volcanic areas but lack the specific knowledge necessary to assess critically the dating procedures performed by scientists with different backgrounds.
Direct dating of volcanics can be affected by (a) the similar and low partition coefficients for uranium and thorium shown by many major constituents of volcanic rocks, (b) the occlusion, within the major minerals, of minor ones particularly enriched in uranium and thorium, (c) uranium loss caused by alteration, (d) the various phases used to draw the isochrone being of different ages, (e) problems connected to isotopic homogeneity of magma. The main difficulties that arise when dating travertine derive from the presence of a non-carbonate phase containing 230Th that has not been generated within the travertine post-depositionally.
These troublesome occurrences are discussed and methods of assessing them are suggested
Lumenless and Stylet-Driven Leads for Left Bundle Branch Area Pacing: Materials, Techniques, Benefits, and Trade-Offs of the Two Approaches
No full textLeft bundle branch area pacing (LBBPa) is an innovative technique for physiological pacing. Compared with His bundle pacing, LBBPa provides better pacing thresholds, lower rates of macrodislodgment, and a reliable strategy for cardiac resynchronization. LBBPa traditionally employs lumenless leads (LLL), which are characterized by small lead bodies and a fixed helix design. These features guarantee stability, avoid helix retraction, and facilitate easier septal penetration, all contributing to an advantageous learning curve. On the other hand, stylet-driven pacing leads (SDL) have shown comparable success rates related to lumenless pacing leads, although they carry risks of helix retraction and lead fracture. SDL have been increasingly employed with favorable results, as they provide good maneuverability and support during implantation with continuous monitoring of ECG-paced morphology. Different manufacturers are offering a variety of SDL, and new dedicated tools are being developed to simplify lead implantation. In this review, we examine the procedural techniques, advantages, and limitations of the most commonly used pacing leads and tools for LBBPa, and we summarize the complications associated with both lumenless leads (LLL) and stylet-driven leads (SDL). © 2024 by the authors
