Surface evidence of active tectonics along the Pergola-Melandro
No full textThe Pergola-Melandro basin (southern Apennines) is characterized by a below-average release of seismic energy within a wider earthquake-prone region. In fact, it is placed between the maximum intensity areas of two of the most destructive earthquakes reported in the Italian seismic catalogue: theM≥7.0 Agri Valley earthquake in 1857 and the Ms = 6.9 Irpinia earthquake in 1980. In thiswork, we present geomorphologic analysis, electrical resistivity surveys and field data, including paleoseismologic evidence, that
provided the first direct constraints on the presence of a∼20 kmlong, seismogenic fault at the western border of the Pergola-Melandro
basin. We also obtained geological information on the recent deformation history of the Pergola-Melandro fault that indicates the occurrence of at least four surface faulting earthquakes since Late Pleistocene age. The empirical relationships linking fault length and magnitude would assign to the Pergola-Melandro fault an event of M≥6.5. These new data have important implication on the
seismic hazard assessment of this sector of the Apennines, that also includes large cities such as Potenza, about 20 km far from the recognized Pergola-Melandro fault, and highlight the relevance of the geological approach in areas where the seismological records are poor. Finally, we discuss the Pergola-Melandro fault within the regional seismotectonic context. In particular, this fault belongs to the system of normal faults with an apenninic orientation, both NE and SW dipping, accommodating the NE-crustal extension taking place in the area. Nearby faults, similarly oriented but with opposite dip, may coexist whether linked by secondary faults that act as slip transfer structures. This complex system of active faults would be more realistic than a narrow band of faults running along the belt axis with an homogenous geometry, and moreover, it is more consistent with the high extension rate measured by historical earthquakes and geodetic data.funded by the National Group for Protection

No full textThe Pergola-Melandro basin (southern Apennines) is characterized by a below-average release
of seismic energy within a wider earthquake-prone region. In fact, it is placed between the
maximum intensity areas of two of the most destructive earthquakes reported in the Italian seismic
catalogue: the M ≥ 7.0 Agri Valley earthquake in 1857 and the Ma = 6.9 Irpinia earthquake in 1980.
In this work, we present geomorphologic analysis, electrical resistivity surveys and field data,
including paleoseismologic evidence, that provided the first direct constraints on the presence of a
~20 km long, seismogenic fault at the western border of the Pergola-Melandro basin. We also
obtained geological information on the recent deformation history of the Pergola-Melandro fault
that indicates the occurrence of at least four surface faulting earthquakes since Late Pleistocene age.
The empirical relationships linking fault length and magnitude would assign to the Pergola-
Melandro fault an event of M ≥ 6.5. These new data have important implication on the seismic
hazard assessment of this sector of the Apennines, that also includes large cities such as Potenza,
about 20 km far from the recognized Pergola-Melandro fault, and highlight the relevance of the
geological approach in areas where the seismological records are poor. Finally, we discuss the
Pergola-Melandro fault within the regional seismotectonic context. In particular, this fault belongs
to the system of normal faults with an apenninic orientation, both NE and SW dipping, that
accommodate the NE- crustal extension taking place in the area. Nearby faults, similarly oriented
but with opposite dip, may coexist whether linked by secondary faults that act as slip transfer
structures. This complex system of active faults would be more realistic than to consider a narrow

consistent with the high extension rate measured by historical earthquakes and geodetic data.Submittedope
Age disparities in transplantation
No full textPurpose of review: The aim of this review is to outline disparities in liver and kidney transplantation across age spectrum. Disparities do not involve only recipients whose age may severely affect the possibility to access to a potentially life-saving procedure, but donors as well. The attitude of transplant centers to use older donors reflects on waiting list mortality and drop-out. This review examines which age categories are currently harmed and how different allocation systems may minimize disparities.
Recent findings: Specific age categories suffer disparities in the access to transplantation. A better understanding of how properly evaluate graft quality, a continuous re-evaluation of the most favorable donor-to-recipient match and most equitable allocation system are the three key points to promote 'justice and equality' among transplant recipients.
Summary: The duty to protect younger patients waiting for transplantation and the request of older patients to have access to potentially life-saving treatment urge the transplant community to use older organs thus increasing the number of available grafts, to evaluate new allocation systems with the aim to maximize 'utility' while respecting 'equity' and to avoid 'futility' thus minimizing waiting list mortality and drop-out, and improving the survival benefits for all patients requiring a transplant
Hybrid partial ALPPS. a feasible approach in case of right trisegmentectomy and macrovascular invasion
No full textI read with great interest the excellent
article ‘‘The Impact of Different Surgical
Techniques on Outcomes in Laparoscopic
Sleeve Gastrectomies’’1 from Berger et al,
published in the September 2016 issue of
Annals of Surgery. The role of the impact
of different technical details on the outcome
of sleeve gastrectomies is particularly
relevant, and several aspects pointed out by
the authors certainly deserve the maximum
attention of the international bariatric
surgical community.
The set of data reported in the study is
impressive and very informative. However,
some concerns need to be raised because they
constitute excellent examples of the strength
and limitations of a data registry observational
retrospective study, even if large and very
well conducted.
One of the main conclusion of the
article is related to the increased risk of a
leak associated with buttressing. Certainly,
the authors clarify that the literature on staple
line reinforcement has conflicting results.
They also acknowledge the lack of specific
information about the buttressing products
used in their series. This limitation is, indeed,
very relevant as it has been shown that there
are significant differences between them
VIABILITY TESTING DURING NORMOTHERMIC MACHINE PERFUSION REQUIRES BOTH HEPATOCELLULAR AND CHOLANGIOCELLULAR CRITERIA
No full textHistory of Robotic Surgery
No full textThe history of telerobotic surgery involves a revolutionary approach to minimally-invasive surgery. The concept of “telemanipulation” or “telepresence” emerged in the 1940s and was first used to describe the sensation that a person is in one location willIe being in another. It was driven by the need for certain complex tasks to be perfoffiled by machines in hazardous and unhealthy environment for human beings, such as the bottom of the ocean or in outer space. In Robert Heinlein’s 1942 science fiction , entitled “Waldo”, the lead character, Waldo Farthingwaite-Jones, was bom frail and unable to lift his own body weight. Heilnlein describes a glove and hamess device that allowed Waldo to control a powerful mechanical arm by simply moving his hand and fingers
