The missing piece. The perceived marginalization of CSOs and HRGs in SOSTs' decision-making processes: a review.

This review represents the first contribution of a research diptych which stems from the activities implemented in the framework of the H2020 ARESIBO project (Augmented Reality Enriched Situation awareness for Border security). The general objective of ARESIBO is to improve the efficiency of border surveillance systems by providing the operational teams, as well as the tactical command and control level with accurate and comprehensive information related to border control considering different issues and perspectives. These perspectives also include the analysis of the level of engagement and the (possible) enhancement of citizens' involvement in the development and decision making related to border surveillance. The principal human rights and migration International Organisations (IOs), as well as EU institutions dealing with security and external borders (i.e., Frontex), agree and state that human rights groups (HRGs) and civil society organisations (CSOs) should be more involved and integrated in border surveillance. That stated, the main goal of this paper is to analyse this perceived marginalisation of CSOs and HRGs, as it emerges from several HRGs' and CSOs' statements on that regard in order to explore the reasons of this perceived marginalisation, as well as the elements that on the contrary seem to make this marginalisation less substantial. The results of this non-systematic review in the framework of ARESIBO led to the elaboration of an innovative participatory model that will be analysed in detail in the second article of this research diptych, entitled "Towards the engagement of citizens in SOSTs decision-making: participatory models setting a common ground for border surveillance and respect of fundamental rights. The case of ARESIBO H2020 project".

Long-Term Outcomes of Transvenous Lead Extraction: A Comparison in Patients with or without Infection from the Italian Region with the Oldest Population.

BACKGROUND: The gold standard for the treatment of cardiac implantable electronic devices (CIEDs)-related infection and lead malfunction is transvenous lead extraction (TLE). To date, the risk of mortality directly related to TLE procedures is relatively low, but data on post-procedural and long-term mortality are limited, even more in the aging population. METHODS: Consecutive patients with CIEDs who underwent TLE were retrospectively studied. The primary outcome was the endpoint of death, considering independent predictors of long-term clinical outcomes in the TLE aging population comparing patients with and without infection. RESULTS: One hundred nineteen patients (male 77%; median age 76 years) were included in the analysis. Eighty-two patients (69%) documented infection, and thirty-seven (31%) were extracted for a different reason. Infected patients were older (80 vs. 68 years, p-value > 0.001) with more implanted catheters (p-value < 0.001). At the last follow-up (FU) available (median FU 4.1 years), mortality reached 37% of the patient population, showing a statistically significant difference between infected versus non-infected groups. At univariable analysis, age at TLE, atrial fibrillation, and anemia remained significant correlates of mortality; at multivariable analysis, only patients with anemia and atrial fibrillation have a 2.3-fold (HR 2.34; CI 1.16-4.75) and a 2.5-fold (HR 2.46; CI 1.33-4.54) increased rate of death, respectively. CONCLUSION: Our long-term data showed that aging patients who underwent TLE for CIED-related infection exhibit a high mortality risk during a long-term follow-up, potentially leading to a rapid and effective procedural approach in this patient population.

COVID-19 Specific Immune Markers Revealed by Single Cell Phenotypic Profiling.

COVID-19 is a viral infection, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and characterized by a complex inflammatory process and clinical immunophenotypes. Nowadays, several alterations of immune response within the respiratory tracts as well as at the level of the peripheral blood have been well documented. Nonetheless, their effects on COVID-19-related cell heterogeneity and disease progression are less defined. Here, we performed a single-cell RNA sequencing of about 400 transcripts relevant to immune cell function including surface markers, in mononuclear cells (PBMCs) from the peripheral blood of 50 subjects, infected with SARS-CoV-2 at the diagnosis and 27 healthy blood donors as control. We found that patients with COVID-19 exhibited an increase in COVID-specific surface markers in different subsets of immune cell composition. Interestingly, the expression of cell receptors, such as IFNGR1 and CXCR4, was reduced in response to the viral infection and associated with the inhibition of the related signaling pathways and immune functions. These results highlight novel immunoreceptors, selectively expressed in COVID-19 patients, which affect the immune functionality and are correlated with clinical outcomes.

Pharmacokinetics and pharmacodynamics of ticagrelor in the treatment of cardiac ischemia.

INTRODUCTION: After acute coronary syndromes (ACS), the so-called dual antiplatelet therapy (DAPT), which usually consists of low-dose of aspirin in combination with a thienopyridine (clopidogrel, prasugrel) or with a cyclopentyltriazolopyrimidine (ticagrelor), reduces the risk of ischemic events. Ticagrelor, un particular, is an effective drug as it isn' a prodrug, doesn't require metabolic activation and demonstrates a rapid onset and faster offset of action. Areas covered: This article evaluates the pharmacokinetics, efficacy, safety and tolerability of ticagrelor during DAPT after ACS and its potential use beyond the canonical twelve months after PCI. The review discusses studies comparing: ticagrelor and clopidogrel (DISPERSE, DISPERSE-2, PLATO, RESPOND Trial, ONSET/OFFSET Trials), ticagrelor and placebo (PEGASUS TIMI 54 Trial). Expert opinion: For ACS patients, the PLATO trial showed that ticagrelor was superior to clopidogrel in the reduction of cardiovascular death, myocardial infarction and stroke. PEGASUS TIMI 54 showed that patients in whom ischemic events and cardiovascular death outweigh the risk of life-threatening bleeding, may benefit from prolonged ticagrelor-based dual antiplatelet therapy, over 12 months. This strategy has been recently approved by the ACC/AHA guidelines. Further studies are needed to evaluate and eventually validate the role of the prolonged DAPT in patients treated with new generation stents.

Pharmacokinetic and pharmacodynamic profile of dronedarone , a new antiarrhythmic agent for the treatment of atrial fibrillation.

INTRODUCTION: Atrial fibrillation (AF) is the most common arrhythmia and is associated with increased morbidity and mortality. Dronedarone is a recent antiarrhythmic drug that has been developed for treatment of AF, with electrophysiological properties similar to amiodarone but with a lower incidence of side effects. AREAS COVERED: This review evaluates the efficacy, safety, tolerability and side effects of dronedarone in the treatment of AF. In particular, the review includes studies comparing: dronedarone and placebo (ANDROMEDA, ATHENA, DAFNE, ERATO, EURIDIS/ADONIS, HESTIA, PALLAS trials), dronedarone and amiodarone (DIONYSOS trial), ranolazine and dronedarone given alone and in combination (HARMONY trial). EXPERT OPINION: Dronedarone is an interesting antiarrhythmic agent in well-selected groups of patients. It also has several other pleiotropic effects that may potentially be beneficial in clinical practice, such as the reduction of the risk of stroke and acute coronary syndromes. In addition, combination therapies such as those with dronedarone and ranolazine, currently being investigated in the HARMONY trial, may provide another interesting approach to increase the antiarrhythmic efficacy and further reduce the incidence of side effects. A better understanding of the mechanisms underlying dronedarone's pleiotropic actions is expected to facilitate the selection of patients benefiting from dronedarone, as well as the development of novel antiarrhythmic drugs for AF.
