Myocardial Involvement in Catastrophic Antiphospholipid Syndrome during Pregnancy or Puerperium: A Case of a Young Breastfeeding Woman and Literature Review.

Catastrophic Antiphospholipid Syndrome (CAPS) is a rare complication that can occur in patients with Antiphospholipid Syndrome (APS). CAPS occurs even more rarely during pregnancy/puerperium and pregnant patients, even less likely to show cardiac involvement without signs of damage on ultrasound and angiography with non-obstructive coronary arteries. We present a case of a 26-year-old breastfeeding woman, the youngest described with CAPS and acute myocardial infarction, whose diagnosis was made with cardiac magnetic resonance imaging (CMRI).

Case Report: Severe Aortic Valve Regurgitation and Pseudoaneurysm in Aortic Valve-Sparing Operation: The Usefulness of Multimodality Imaging in a Complex Clinical Scenario.

Failure of the native aortic valve and degenerative anatomy of ascending aorta in patients with previous Tirone-David operation may represent a clinical challenge, because sometimes the risk of reoperation is prohibitive. We described the case of a patient suffering from severe aortic valve regurgitation and pseudoaneurysm of the aortic arch, 6 years after cardiac surgery operation. The aim of this clinical case was to assess if the complex anatomy of aortic pseudoaneurysm and aortic root geometry can be accurately reproduced from contrast-enhanced computed tomography scan into a three-dimensional (3D) printed model.

Network meta-analysis on patent foramen ovale: is a stroke or atrial fibrillation worse?

Objective: Systematic reviews suggest that patent foramen ovale closure (PFOc) is performed percutaneously with low complication rates. We did a network meta-analysis (NMA) comparing devices for PFO closures, evaluating safety and efficacy of transcatheter PFOc in preventing neurological events in patients with stroke when compared with medical therapy (MT), and assessing risk of atrial fibrillation (AF).

Methods: We searched 3 databases (MEDLINE, EMBASE, CENTRAL/CCTR) identifying six randomized controlled trials from 2012 until December 2019.

The Closure of Patent Foramen Ovale in Preventing Subsequent Neurological Events: A Bayesian Network Meta-Analysis to Identify the Best Device.

Background: Randomized-controlled trials (RCTs) reported a finding on the safety and efficacy of percutaneous patent foramen ovale (PFO) closure to prevent stroke recurrence. It showed that the Amplatzer (AMP) device appears to be superior to medical therapy (MT) in preventing strokes and episodes of atrial fibrillation (AF), than other devices. We performed a network meta-analysis (NMA) to evaluate the closure of PFO in preventing subsequent neurological events while investigating the results obtained by specific devices.

Exclusion of a coronary aneurysm with a polyurethane-covered stent.

A coronary artery aneurysm is a challenging cli-nical situation due to the lack of sufficient evidence from randomized controlled studies and the lack of consensus on a management strategy. The present case is a description of the exclusion of a middle segment aneurysm of the left circumflex coronary artery using a PK Papyrus covered stent (Biotronik, AG, Bulach, Switzerland). The final images were favorable.

IL-17 signaling components in bivalves: Comparative sequence analysis and involvement in the immune responses.

The recent discovery of soluble immune-regulatory molecules in invertebrates takes advantage of the rapid growth of next generation sequencing datasets. Following protein domain searches in the transcriptomes of 31 bivalve spp. and in few available mollusk genomes, we retrieved 59 domains uniquely identifying interleukin 17 (IL-17) and 96 SEFIR domains typical of IL-17 receptors and CIKS/ACT1 proteins acting downstream in the IL-17 signaling pathway.

Dual analysis of host and pathogen transcriptomes in ostreid herpesvirus 1-positive Crassostrea gigas.

Ostreid herpesvirus type 1 (OsHV-1) has become a problematic infective agent for the Pacific oyster Crassostrea gigas. In particular, the OsHV-1 μVar subtype has been associated with severe mortality episodes in oyster spat and juvenile oysters in France and other regions of the world. Factors enhancing the infectivity of the virus and its interactions with susceptible and resistant bivalve hosts are still to be understood, and only few studies have explored the expression of oyster or viral genes during productive infections.

Mortality occurrence and pathogen detection in Crassostrea gigas and Mytilus galloprovincialis close-growing in shallow waters (Goro lagoon, Italy).

The complex interactions occurring between farmed bivalves and their potential pathogens in the circumstances of global climate changes are current matter of study, owing to the recurrent production breakdowns reported in Europe and other regions of the world. In the frame of Project FP7-KBBE-2010-4 BIVALIFE, we investigated the occurrence of mortality and potential pathogens during the Spring-Summer transition in Crassostrea gigas and Mytilus galloprovincialis cohabiting in the shallow waters of one northern Italian lagoon (Sacca di Goro, Adriatic Sea) and regarded as susceptible and resistant species, respectively. In 2011, limited bivalve mortality was detected in the open-field trial performed with 6-12 month old spat whereas subsequent trials with 2-3 month old spat produced almost complete (2012) and considerable (2013) oyster mortality.

[Coronary artery disease: diagnostic approach in 2013].

Coronary disease can lead to very serious complications which sometimes may have dramatic consequences on the quality of life of our patients. In addition, it can also have numerous social repercussions including a significant increase in the health budget costs. Systematic evaluation adapted to each patient is crucial.

DNA damage and transcriptional changes in the gills of mytilus galloprovincialis exposed to nanomolar doses of combined metal salts (Cd, Cu, Hg).

Aiming at an integrated and mechanistic view of the early biological effects of selected metals in the marine sentinel organism Mytilus galloprovincialis, we exposed mussels for 48 hours to 50, 100 and 200 nM solutions of equimolar Cd, Cu and Hg salts and measured cytological and molecular biomarkers in parallel. Focusing on the mussel gills, first target of toxic water contaminants and actively proliferating tissue, we detected significant dose-related increases of cells with micronuclei and other nuclear abnormalities in the treated mussels, with differences in the bioconcentration of the three metals determined in the mussel flesh by atomic absorption spectrometry. Gene expression profiles, determined in the same individual gills in parallel, revealed some transcriptional changes at the 50 nM dose, and substantial increases of differentially expressed genes at the 100 and 200 nM doses, with roughly similar amounts of up- and down-regulated genes.

Massively parallel amplicon sequencing reveals isotype-specific variability of antimicrobial peptide transcripts in Mytilus galloprovincialis.

Background: Effective innate responses against potential pathogens are essential in the living world and possibly contributed to the evolutionary success of invertebrates. Taken together, antimicrobial peptide (AMP) precursors of defensin, mytilin, myticin and mytimycin can represent about 40% of the hemocyte transcriptome in mussels injected with viral-like and bacterial preparations, and unique profiles of myticin C variants are expressed in single mussels. Based on amplicon pyrosequencing, we have ascertained and compared the natural and Vibrio-induced diversity of AMP transcripts in mussel hemocytes from three European regions.

Insights into the innate immunity of the Mediterranean mussel Mytilus galloprovincialis.

Background: Sessile bivalves of the genus Mytilus are suspension feeders relatively tolerant to a wide range of environmental changes, used as sentinels in ecotoxicological investigations and marketed worldwide as seafood. Mortality events caused by infective agents and parasites apparently occur less in mussels than in other bivalves but the molecular basis of such evidence is unknown. The arrangement of Mytibase, interactive catalogue of 7,112 transcripts of M.

Mediterranean mussel gene expression profile induced by okadaic acid exposure.

Seasonal seawater temperature increases define optimal growth conditions for Dinoflagellate species which can reach high concentrations in water column and also in filter-feeding organisms like Mytilus galloprovincialis. Commonly produced by Dinophysis and Prorocentrum spp., okadaic acid (OA) and its analogues are responsible for the Diarrheic Shellfish Poisoning (DSP) syndrome in humans.

Diagnostic criteria for apical ballooning derived from quantitative analysis of left ventricular angiograms.

Aim: The aim of this study was to evaluate diagnostic criteria for apical ballooning (AB) derived from quantitative analysis of left ventricular angiograms. AB is an unusual cause of left ventricular dysfunction mimicking acute transmural ischemia (STEMI).

Methods: This study compared the systolic and diastolic linear measures of left ventricle (LV) of ten consecutive patients with AB to those obtained in a control group of STEMI patients.

MytiBase: a knowledgebase of mussel (M. galloprovincialis) transcribed sequences.

Background: Although bivalves are among the most studied marine organisms due to their ecological role, economic importance and use in pollution biomonitoring, very little information is available on the genome sequences of mussels. This study reports the functional analysis of a large-scale Expressed Sequence Tag (EST) sequencing from different tissues of Mytilus galloprovincialis (the Mediterranean mussel) challenged with toxic pollutants, temperature and potentially pathogenic bacteria.

Results: We have constructed and sequenced seventeen cDNA libraries from different Mediterranean mussel tissues: gills, digestive gland, foot, anterior and posterior adductor muscle, mantle and haemocytes.

'Bail-out' bivalirudin use in patients with thrombotic complications unresponsive to conventional treatment during percutaneous coronary intervention.

Percutaneous coronary intervention (PCI) is routinely performed in patients with non-ST elevation acute coronary syndromes after pretreatment with clopidogrel and periprocedural administration of unfractionated heparin on a weight-adjusted basis. Although activated clotting time (ACT) monitoring is encouraged to verify the adequacy of anticoagulation during the procedures, this is not a common practice in many laboratories. The authors describe 4 cases of patients with bifurcation lesions involving the left anterior descending coronary artery, who developed periprocedural thrombosis with acute transmural ischemia.

Development of mussel mRNA profiling: Can gene expression trends reveal coastal water pollution?

Marine bivalves of the genus Mytilus are intertidal filter-feeders commonly used as biosensors of coastal pollution. Mussels adjust their functions to ordinary environmental changes, e.g.

Right ventricular function predicts transplant-free survival in idiopathic dilated cardiomyopathy.

Background: Right ventricular function may be reduced in patients with idiopathic dilated cardiomyopathy (IDC). The prognostic implications of right ventricular dysfunction have not been investigated in this group of patients.

Methods: In a series of 120 consecutive patients with IDC [defined as a left ventricular ejection fraction (LVEF) < 55%, normal coronary arteries and no other causes for left ventricular dysfunction], right ventricular function was prospectively evaluated by means of angiocardiography at the time of catheterization.

Left ventricular stroke work reserve as prognostic marker in severe heart failure.

Aim: We sought to determine whether an invasive approach based on Swan-Ganz catheterization, coupled with a pharmacologic stressor, might help stratify prognosis in patients with severe heart failure and uniformly depressed indices of cardiac function.

Methods: We studied 31 unselected consecutive patients with scalar doses of dobutamine (2.5-10 microg/kg/min) after baseline hemodynamic evaluation.

Abciximab in ST-elevation acute myocardial infarction occurring in a heart transplant recipient and treated with stenting.

The authors describe primary coronary intervention consisting of direct stenting after abciximab administration in a case of acute anterior myocardial infarction occurring in a heart transplant recipient with triple-vessel disease. Primary success was obtained and the patient survived to a one-year angiographic follow up which showed persistent coronary patency. This is the first report concerning the use of abciximab in primary stenting for acute myocardial infarction in allograft coronary artery disease.

Frequency and determinants of direct stenting in routine percutaneous coronary interventions: data on 835 consecutive procedures in a single center.

Background: Recent studies evaluated the technique of direct coronary stenting as compared to stenting-after-predilation in selected anatomic and clinical settings. However, the impact of direct stenting in routine interventional practice remains poorly elucidated.

Methods: From April 1999 to March 2001, all percutaneous coronary interventions performed at our Center were prospectively analyzed to determine the frequency of direct stenting, the success rate and the variables associated with its utilization.

Usefulness of 99mTc-pertechnetate scintigraphy and fine-needle aspiration cytology in patients with solitary thyroid nodules and thyroid cancer.

The aim of this study was to evaluate the accuracy of fine-needle aspiration (FNA) cytology and thyroid scintigraphy (TS) in patients with solitary thyroid nodules. We retrospectively reviewed a series of 657 consecutive patients (531 (80.8%) women and 126 (19.
