Rationale: In-stent reocclusion after endovascular therapy has a negative impact on outcomes in acute ischemic stroke (AIS) due to tandem lesions (TL). Optimal antiplatelet therapy approach in these patients to avoid in-stent reocclusion is yet to be elucidated.
Aims: To assess efficacy and safety of intravenous tirofiban versus intravenous aspirin in patients undergoing MT plus carotid stenting in the setting of AIS due to TL.
A novel adaptive super-twisting control algorithm, for Unmanned Surface Vehicles (USV) tracking control is presented. The proposed adaptive law is obtained using a Lyapunov approach, to analyze the system closed-loop stability. Furthermore, several conditions are given to guarantee robustness in presence of unknown bounded disturbances/uncertainties, chattering mitigation and the finite-time convergence.

Background: In-stent thrombosis after mechanical thrombectomy (MT) worsen outcomes in acute ischemic stroke (AIS) due to tandem lesions (TL). Although an optimal antiplatelet therapy is needed, the best approach to avoid in-stent thrombosis is yet to be elucidated.
Hypothesis: Low-dose intravenous tirofiban is superior to intravenous aspirin in avoiding in-stent thrombosis in patients undergoing MT plus carotid stenting in the setting of AIS due to TL.
Aims: Carotid reocclusion (CRO) after mechanical thrombectomy (MT) in acute ischemic stroke (AIS) due to tandem lesion (TL) or isolated internal carotid occlusion (ICO) is associated with worse clinical outcomes. Our aim was to analyze the predictors and clinical impact of CRO.
Methods: A retrospective single-center analysis of all patients with anterior circulation strokes who underwent MT prospectively included in a registry between 2017 and 2020 was performed.
Pan-Immune-Inflammation Value (PIV) has been recently proposed as a new blood-based prognostic biomarker in metastatic colorectal cancer (mCRC). Herein we aimed to validate its prognostic significance and to evaluate its utility for disease monitoring in patients with mCRC receiving first-line chemotherapy. We conducted a single-centre retrospective study involving 130 previously untreated mCRC patients under first-line standard chemotherapy in a real-world scenario.

However, there is limited information of IVT in those patients in real-world studies.

Bone marrow mononuclear cell (BM-MNC) transplantation improves recovery in experimental models of ischemic stroke that might be related with miRNA modifications. However, its effect on circulating miRNA has not been described in patients with stroke.

Background: CHS is a severe complication following CAS. The presence of clinical manifestations is estimated on the basis of retrospective reviews and is still uncertain.
Complete transection of the common femoral artery is more frequent after penetrating injuries than after blunt trauma, with most of the cases occurring in combination with fractures. Contusion from a bicycle handlebar is a rare form of injury to the femoral vessels. Hereby, we present a case of complete common femoral artery transection caused by a direct bicycle handlebar trauma.

In order to modulate PDE activity in a selective way, we focused our efforts on the search of allosteric modulators. Based on the crystal structure of the PDE10A GAF-B domain, a virtual screening study allowed the discovery of new hits that were also tested experimentally, showing inhibitory activities in the micromolar range.

Methodology & results: To study the utility of PDE10A as a pharmacological target for PD, in this work we propose the search and development of new PDE10A inhibitors that could be useful as pharmacological tools in models of the disease and presumably as potential drug candidates. By using different medicinal chemistry approaches we have discovered imidazole-like PDE10A inhibitors and showed their neuroprotective actions.

The following step in this travel to unravel PDE7 is the design of more selective inhibitors. In this sense we have proposed to perform an analysis of PDE7 surface to identify possible allosteric sites following by a docking study of different PDE7 inhibitors synthesized by our group.

Head and neck involvement occurs only in 15% to 20% of cases. The recommended treatment in solitary CD is radical resection.

Methods: We examined 359 consecutive patients.
Coronary artery fistulas are one of the most common congenital anomalies of the coronary arteries. Most fistulas are small and of no clinical significance, although larger or multiple fistulas can be symptomatic and produce complications. Early percutaneous occlusion is now always recommended, and surgical closure is restricted to use for multiple or large fistulas.
