Background: Iron overload and hepatitis C virus (HCV) infection together can lead to chronic liver damage in thalassemia major (TM) patients.

Aims: We investigated viral, genetic, and disease factors influencing sustained virological response (SVR) after peg-interferon and ribavirin therapy in TM patients with HCV infection.

Methods: We analyzed 230 TM patients with HCV infection (mean age 36.

Association between postoperative thromboembolism prophylaxis and complications following urological surgery.

Thromboembolism represents the most significant complication and cause of non-surgical mortality in major urological surgery. The aim of the present study was to assess the association between the type of pharmacological thromboembolism prophylaxis and the postoperative complication rate in a cohort of patients undergoing major urological surgery. All consecutive patients treated with major urological surgery between December 2011 and March 2013 were evaluated.

Margins in breast conserving surgery: A practice-changing process.

Margins in breast conserving surgery (BCS) have been a long standing subject debate. This largely arises from the absence of a consensus on what constitutes an adequate margin width, resulting in re-excision rates of 25-40% for close or positive margins and its consequent impact upon cosmesis, economic costs, patient dissatisfaction and lack of bearing on survival. Accepting that the increased risk of local recurrences (LR) has its influence on survival, the decrease in LR in BCS in the last decade have been motivated by better surgical techniques for assessing negative margins, use of targeted therapies and in general with the multimodal treatment in the management of breast cancer patients.

The value of imaging in subclinical coronary artery disease.

Although the treatment of acute coronary syndromes (ACS) has advanced considerably, the ability to detect, predict, and prevent complications of atherosclerotic plaques, considered the main cause of ACS, remains elusive. Several imaging tools have therefore been developed to characterize morphological determinants of plaque vulnerability, defined as the propensity or probability of plaques to complicate with coronary thrombosis, able to predict patients at risk. By utilizing both intravascular and noninvasive imaging tools, indeed prospective longitudinal studies have recently provided considerable knowledge, increasing our understanding of determinants of plaque formation, progression, and instabilization.

Use of newer prognostic indices for patients with myelodysplastic syndromes in the low and intermediate-1 risk categories: a population-based study.

Background: We aimed to compare the ability of recently developed prognostic indices for myelodysplastic syndromes to identify patients with poor prognoses within the lower-risk (low and intermediate-1) categories defined by the International Prognosis Scoring System (IPSS).

Methods: We included patients with de-novo myelodysplastic syndromes diagnosed between Nov 29, 1972, and Dec 15, 2011, who had low or intermediate-1 IPSS scores and were in the Spanish Registry of Myelodysplastic Syndromes. We reclassified these patients with the new prognostic indices (revised IPSS [IPSS-R], revised WHO-based Prognostic Scoring System [WPSS-R], Lower Risk Scoring System [LRSS], and the Grupo Español de Síndromes Mielodisplásicos [Spanish Group of Myelodysplastic Syndromes; GESMD]) and calculated the overall survival of the different risk groups within each prognostic index to identify the groups of patients with overall poor prognoses (defined as an expected overall survival <30 months).

Randomized evaluation of intralesion versus intracoronary abciximab and aspiration thrombectomy in patients with ST-elevation myocardial infarction: The COCTAIL II trial.

Background: Thrombus burden and distal embolization are predictive of no-reflow during primary percutaneous coronary intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI). We sought to compare the efficacy of pharmacological and catheter-based strategies for thrombus in patients with STEMI and high atherothrombotic burden.

Methods: Between January 2012 and December 2013, 128 STEMI patients undergoing primary PCI at 5 centers were randomly assigned in a 2 × 2 factorial design to intracoronary (IC) abciximab bolus (via the guide catheter) versus intralesion (IL) abciximab bolus, each with versus without aspiration thrombectomy (AT).

Methods: A total of 694 consecutively biopsied Caucasian G1 CHC patients were genotyped for TM6SF2 rs58542926, IL28B rs12979860 and PNPLA3 rs738409. Steatosis was classified as absent (<5%), mild-moderate(5-29%) and severe(≥30%), Fibrosis was considered severe if=F3-F4.

Serial optical coherence tomography imaging of ACS-causing culprit plaques.

Aims: The aim of this study was to understand better the mechanisms of repair of plaque complications causing acute coronary syndrome.

Methods And Results: We used OCT in the acute phase and at follow-up (one to seven months) to investigate the plaque healing in 10 culprit plaques: five ruptured fibrous cap (RFC) and five intact fibrous cap (IFC) which were not treated with stent deployment and caused ST-segment elevation myocardial infarction (n=8) and non-STEMI (n=2). At follow-up OCT, the margins of the evacuated cavity in RFC plaques showed a smooth surface and a morphology similar to that of baseline images, while IFC plaques showed a smoothened intimal border and a double layering indicating organising thrombus incorporated in the superficial layers of the plaque.

The severity of steatosis influences liver stiffness measurement in patients with nonalcoholic fatty liver disease.

Unlabelled: In nonalcoholic fatty liver disease, the influence of severity of steatosis on liver stiffness measurement (LSM) is poorly studied and still debated. We assessed the impact of steatosis severity and its ultrasonographic (US) sign, severe bright liver echo pattern, on LSM values and on transient elastography accuracy for the diagnosis of liver fibrosis in a cohort of consecutive patients with nonalcoholic fatty liver disease. Patients (n = 253) were assessed by clinical, US, and histological (Kleiner score) features.

Impact of HBV genotypes A and D genetic variability on infection evolution.

HBV is characterized by a high genetic variability, which is the basis of its classification into eight genotypes (A-H). HBV infection is associated with different outcomes, from self-limiting acute hepatitis to active chronic hepatitis, asymptomatic carriage, and occult infection. The aim of this study was to analyze the genetic variability of HBV genotypes A and D isolates from 79 cases of self-limiting acute hepatitis and chronic hepatitis, in order to identify HBV variants associated with resolution or chronicity of acute HBV infection.

The metallome of the human placenta in gestational diabetes mellitus.

Obtaining the knowledge of the "omics" and therefore of the metallomics of gestational diabetes mellitus (GDM) appears to be a necessary task to obtain information about the molecular causes of this disease. In this study, the metallome of GDM and of other types of diabetes mellitus was first reviewed. The comparative analysis of the published data revealed that no GDM elemental markers could be identified with sufficient reliability in blood or in the other considered samples, with the partial exception of selenium.
