Bivalirudin Versus Unfractionated Heparin in Acute Coronary Syndromes: An Updated Meta-analysis of Randomized Trials.

Introduction And Objectives: Contrasting data have been reported on bivalirudin as an anticoagulation strategy during percutaneous coronary interventions, offering theoretical benefits on bleeding complications but raising concerns on a potential increase in the risk of stent thrombosis. We performed an updated meta-analysis to evaluate the efficacy and safety of bivalirudin compared with unfractionated heparin in patients undergoing percutaneous interventions for acute coronary syndromes.

Methods: Literature archives and main scientific sessions were scanned.

Survival After Surgical Treatment of Lung Cancer Arising in the Population Exposed to Illegal Dumping of Toxic Waste in the Land of Fires ('Terra dei Fuochi') of Southern Italy.

Aim: Terra dei Fuochi (TdF), the so-called 'Land of Fires' in Southern Italy, is an agricultural territory characterized by illegal dumping of toxic waste known to occur since the 1980s. It is unknown whether prognosis of patients developing cancer and living in that area may differ compared to those living in areas not exposed to this specific type of pollution. We retrospectively analyzed the 5-year survival rates of patients originating from the TdF diagnosed with lung cancer compared to patients from other areas.

Parathyroid Hormone Levels and High-Residual Platelet Reactivity in Patients Receiving Dual Antiplatelet Therapy With Acetylsalicylic Acid and Clopidogrel or Ticagrelor.

Background: High-residual-on-treatment platelet reactivity still represents a challenging issue, potentially vanishing the benefits of dual antiplatelet treatment in patients with coronary artery disease. However, very few is known on the determinants of suboptimal response to antiplatelet agents. Recent interests have emerged on the potential prothrombotic effect of parathyroid hormone (PTH).

Impact of renal function on mean platelet volume and its relationship with coronary artery disease: A single-centre cohort study.

Background: Mean platelet volume (MPV) has been proposed as a marker of platelet reactivity and cardiovascular disease. Chronic kidney disease (CKD) significantly favors the occurrence of cardiovascular events, by increasing the circulating levels of a wide spectrum of pro-oxidant and pro-thrombotic mediators. However, opposite alterations of platelet function, both enhanced aggregability and increased bleeding diathesis have been reported in these patients, with contrasting results on the effects of renal function on MPV and coronary artery disease, that were assessed in present study.

Impact of diabetes on immature platelets fraction and its relationship with platelet reactivity in patients receiving dual antiplatelet therapy.

Contrasting data have been reported so far on the role of reticulated platelets in suboptimal response to antiplatelet therapies. In particular, still unexplored is whether they may contribute to explain the higher risk of thrombotic complications observed in diabetic patients. Aim of the present study was to evaluate the impact of diabetes on the levels of reticulated platelets and its relationship with high residual on-treatment platelet reactivity (HRPR) in patients receiving dual antiplatelet therapy.

Impact of Diabetes on Homocysteine Levels and Its Relationship with Coronary Artery Disease: A Single-Centre Cohort Study.

Background/aims: Coronary artery disease (CAD) is a major cause of mortality worldwide. Hyperhomocysteinemia has been identified as a risk factor for CAD due to increased thrombogenicity, oxidative stress status and endothelial dysfunction. Few data have been provided on the impact of diabetes on homocysteine and its relationship with the prevalence and extent of CAD in this high-risk subset of patients and therefore, this is the aim of this study.

Gender Differences in Platelet Reactivity in Patients Receiving Dual Antiplatelet Therapy.

Background: Cardiovascular risk is still underestimated in women, experiencing higher mortality and worse prognosis after acute cardiovascular events. Gender differences have been reported in thrombotic and hemorrhagic risk during dual antiplatelet therapy (DAPT), thus suggesting a potential variability in platelet reactivity according to sex. The aim of the present study was to assess the role of gender on platelet function and the prevalence of high-on treatment residual platelet reactivity (HRPR) during DAPT in patients with recent acute coronary syndrome or percutaneous coronary revascularization.

Time-related changes in neointimal tissue coverage of a novel Sirolimus eluting stent: Serial observations with optical coherence tomography.

Background: DES has reduced rates of restenosis compared with BMS but it has been associated with delayed healing and increase of stent thrombosis. The aim of our study was to evaluate the vascular time-related changes following implantation of a new SES coated with an amorphous silicon carbide that allows faster re-endothelisation (Orsiro-Biotronik).

Methods: This prospective registry enrolled STEMI-patients with multi-vessel disease, thus candidates for a two-step procedure.

Lung ultrasound in the diagnosis of pneumonia in children: proposal for a new diagnostic algorithm.

Background. Despite guideline recommendations, chest radiography (CR) for the diagnosis of community-acquired pneumonia (CAP) in children is commonly used also in mild and/or uncomplicated cases. The aim of this study is to assess the reliability of lung ultrasonography (LUS) as an alternative test in these cases and suggest a new diagnostic algorithm.

Indications and immediate and long-term results of a novel pericardium covered stent graft: Consecutive 5 year single center experience.

Background: The use of covered stent grafts during percutaneous coronary intervention (PCI) is a life saving solution to seal acute iatrogenic vessel rupture. However, the presence of an impenetrable mechanical barrier is also appealing during treatment of friable coronary plaques but the synthetic PTFE-membrane that might trigger excessive neointimal proliferation has limited its elective-use. Pericardium tissue may offer an appealing "natural" alternative.

Contrast volume to creatinine clearance ratio for the prediction of contrast-induced nephropathy in patients undergoing coronary angiography or percutaneous intervention.

Background: Contrast-induced nephropathy is a common complication of procedures that are likely to use contrast media. The identification of high-risk patients and preventive optimal hydration are key measures to reduce the incidence of contrast-induced nephropathy. The aim of this study was to evaluate the role of the contrast volume to creatinine clearance ratio (V/CrCl) in the prediction of contrast-induced nephropathy after coronary angiography or percutaneous coronary intervention.

Impact of atorvastatin or rosuvastatin co-administration on platelet reactivity in patients treated with dual antiplatelet therapy.

Background: Residual high-on treatment platelet reactivity (HRPR) still represents a challenging matter in patients with coronary artery disease. Drug-to-drug interaction has been suggested between some statin and antiplatelet agents, despite their co-administration is mandatory in patients after an acute cardiovascular event or coronary stenting. Therefore, the aim of the current study was to investigate any impact of rosuvastatin or atorvastatin co-administration on platelet reactivity in patients receiving dual antiplatelet therapy (DAPT).

Platelet reactivity in patients with impaired renal function receiving dual antiplatelet therapy with clopidogrel or ticagrelor.

Background: Suboptimal platelet inhibition still represents an important challenge, especially for patients undergoing percutaneous coronary interventions (PCI). Chronic kidney disease (CKD) is a common comorbidity of patients with coronary artery disease, and may potentially influence platelet reactivity. So far only few studies have assessed the role of CKD on response to dual antiplatelet therapy (DAPT) with conflicting results.

Acetylsalicylic acid desensitization in patients with coronary artery disease: A comprehensive overview of currently available protocols.

Background: Acetylsalicylic acid (ASA) represents the basis of pharmacological therapy for cardiovascular prevention. However, several patients are excluded from the benefits of ASA for hypersensitivity problems, and controversies still exist on their management. The aim of present study was to evaluate the safety and efficacy of ASA desensitization protocols in patients requiring dual antiplatelet therapy for coronary artery disease.

Arena Roof Technique for Complex Reconstruction After Extensive Chest Wall Resection.

Extensive primary resections or redos may produce significant chest wall defects requiring creative reconstructions in order to avoid reduction of the intrathoracic volume. We describe the successful use of an innovative technique for chest wall reconstruction based on the concept of roof coverage of sport arenas. In fact, titanium plates are anchored to the residual rib stumps along the parasternal and paravertebral lines.

Platelet Larger Cell Ratio and High-on Treatment Platelet Reactivity During Dual Antiplatelet Therapy.

Background: Low response to antiplatelet agents has been associated to an increased risk of thrombotic complications and recurrent ischemic events. Platelet size has been proposed as a potential marker of platelet reactivity. Therefore, the aim of the present study was to evaluate the impact of platelet Larger Cell Ratio (p-LCR) on platelet aggregation and the prevalence of residual high-on treatment platelet reactivity (HRPR) in patients receiving dual antiplatelet therapy (DAPT) after a recent acute coronary syndrome or coronary revascularization.

Long-term results of the randomized comparison of everolimus-eluting stents and sirolimus-eluting stent in patients with ST elevation myocardial infarction (RACES-MI trial).

Background: Several concerns have emerged about the higher risk of very late stent thrombosis (ST) with first generation drug-eluting stent (DES), especially in ST-segment elevation myocardial infarction (STEMI) patients undergoing percutaneous coronary intervention (PCI). New generation DES have demonstrated reduction in ST at mid-term follow-up, however no data are available on long-term follow-up. Therefore, the aim of this study was to report long-term results of the RACES-MI trial conducted to compare Everolimus-Eluting Stent (EES) vs Sirolimus-Eluting Stent (SES) in patients undergoing primary PCI.

BIONOTE e-nose technology may reduce false positives in lung cancer screening programmes†.

Objectives: Breath composition may be suggestive of different conditions. E-nose technology has been used to profile volatile organic compounds (VOCs) pattern in the breath of patients compared with that of healthy individuals. BIOsensor-based multisensorial system for mimicking NOse, Tongue and Eyes (BIONOTE) technology differs from Cyranose® based on a set of separate transduction features.

Immature platelet fraction and high-on treatment platelet reactivity with ticagrelor in patients with acute coronary syndromes.

Residual high-on treatment platelet reactivity (HRPR) has been associated with a 2-9 fold increased risk of acute ischemic events in patients with acute coronary syndromes or coronary stenting. However, the mechanism of suboptimal platelet inhibition are still poorly understood. Aim of present study was to evaluate the role of the percentage of reticulated platelets on HRPR with ticagrelor.

Field triage in the ambulance versus referral via non-percutaneous coronary intervention centre in ST-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention: A systematic review.

Aims: The purpose of this study was to determine whether direct ambulance transport of ST-elevation myocardial infarction (STEMI) patients to a percutaneous coronary intervention (PCI) hospital (field triage) leads to a lower 30-day mortality compared to transport via a referral non-PCI hospital (referral via a spoke centre) in STEMI patients.

Methods And Results: We performed a systematic review of interventions. An experienced librarian searched in PubMed, EMBASE.

Platelet GP IIb-IIIa Receptor Antagonists in Primary Angioplasty: Back to the Future.

Coronary artery disease and acute myocardial infarction still represent the leading cause of mortality in developed countries. Therefore, great efforts have been made in the last decades to improve reperfusion strategies and adjunctive antithrombotic therapies. In fact, despite optimal epicardial recanalisation, a large proportion of patients still experience impaired reperfusion and in-stent thrombosis.
