The CARotid plaqUe StabilizatiOn and regression with evolocumab (CARUSO) study is a randomized, single-center, investigator-initiated trial aiming at evaluating carotid plaque morphological stabilization and regression following, respectively, 6 and 12 months of therapy with evolocumab.

Methods: Asymptomatic patients with uni- or bilateral de novo carotid artery stenosis ≥50% and LDL-C values ≥100 mg/dl despite maximum tolerated lipid lowering therapy (LLT) will be randomized to evolocumab 140 mg s.

Management of Nellix migration and type Ia endoleak from proximal endovascular aneurysm sealing relining to late open conversion.

Background: Despite promising early results, midterm failures of the Nellix endovascular aneurysm sealing (EVAS) system (Endologix Inc, Irvine, Calif) have been reported at higher than expected rates. The management of proximal endoleaks and migration differs from those after conventional endovascular aortic aneurysm repair (EVAR) owing to the peculiar design of the Nellix device. In the present study, we report a monocentric experience in the management of EVAS complications using various techniques.

Long-term failure after endovascular aneurysm sealing in a real-life, single-center experience with the Nellix endograft.

Background: Endovascular aneurysm sealing (EVAS) is an innovative alternative to conventional endovascular aneurysm repair (EVAR). EVAS relies on sac anchoring without proximal fixation to achieve sealing and should have allowed for the treatment of a broader range of anatomic features compared with standard EVAR. Despite the encouraging early reports, the mid- and long-term follow-up data have shown increased rates of failure.

Expert Opinion on Hostile Neck Definition in Endovascular Treatment of Abdominal Aortic Aneurysms (a Delphi Consensus).

Background: Endovascular aneurysm repair (EVAR) is currently accepted as an alternative to open repair for the treatment of abdominal aortic aneurysm (AAA). Approximately 40-60% of AAA patients are not considered eligible for EVAR due to unfavorable anatomy. There is currently no consensus on the definition of "hostile" aortic neck for EVAR procedure.

MicroRNAs in the DNA Damage/Repair Network and Cancer.

Cancer is a multistep process characterized by various and different genetic lesions which cause the transformation of normal cells into tumor cells. To preserve the genomic integrity, eukaryotic cells need a complex DNA damage/repair response network of signaling pathways, involving many proteins, able to induce cell cycle arrest, apoptosis, or DNA repair. Chemotherapy and/or radiation therapy are the most commonly used therapeutic approaches to manage cancer and act mainly through the induction of DNA damage.

The inflammatory microenvironment in hepatocellular carcinoma: a pivotal role for tumor-associated macrophages.

Hepatocellular carcinoma (HCC) is one of the most common and aggressive human cancers worldwide. HCC is an example of inflammation-related cancer and represents a paradigm of the relation occurring between tumor microenvironment and tumor development. Tumor-associated macrophages (TAMs) are a major component of leukocyte infiltrate of tumors and play a pivotal role in tumor progression of inflammation-related cancer, including HCC.
