Predicting in-hospital mortality in acute type B aortic dissection: evidence from International Registry of Acute Aortic Dissection.

Background: The outcome of patients with acute type B aortic dissection (ABAD) is strongly related to their clinical presentation. The purpose of this study was to investigate predictors for mortality among patients presenting with ABAD and to create a predictive model to estimate individual risk of in-hospital mortality using the International Registry of Acute Aortic Dissection (IRAD).

Methods And Results: All patients with ABAD enrolled in IRAD between 1996 and 2013 were included for analysis.

Autologous transplantation and maintenance therapy in multiple myeloma.

Background: This open-label, randomized, phase 3 study compared melphalan at a dose of 200 mg per square meter of body-surface area plus autologous stem-cell transplantation with melphalan-prednisone-lenalidomide (MPR) and compared lenalidomide maintenance therapy with no maintenance therapy in patients with newly diagnosed multiple myeloma.

Methods: We randomly assigned 273 patients 65 years of age or younger to high-dose melphalan plus stem-cell transplantation or MPR consolidation therapy after induction, and 251 patients to lenalidomide maintenance therapy or no maintenance therapy. The primary end point was progression-free survival.

A roadmap to investigate the genetic basis of bicuspid aortic valve and its complications: insights from the International BAVCon (Bicuspid Aortic Valve Consortium).

Bicuspid aortic valve (BAV) is the most common adult congenital heart defect and is found in 0.5% to 2.0% of the general population.

Differentiation of rebound and lymphoid thymic hyperplasia from anterior mediastinal tumors with dual-echo chemical-shift MR imaging in adulthood: reliability of the chemical-shift ratio and signal intensity index.

Purpose: To prospectively evaluate (a) effectiveness and limits of dual-echo chemical-shift magnetic resonance (MR) imaging for distinguishing hyperplastic thymus from anterior mediastinal tumors in adulthood by using chemical-shift ratio ( CSR chemical-shift ratio ) and signal intensity index ( SII signal intensity index ), with proposal of optimal threshold value for each, and (b) whether age affects these indexes.

Materials And Methods: Study was institutional review board approved, with informed consent obtained. Ninety-two subjects (53 men, 39 women; age range, 18-84 years) were divided into a rebound and lymphoid hyperplasia group (group A, 30 patients) and a tumor group (group B, 62 patients).

Whole exome sequencing for the identification of a new mutation in TGFB2 involved in a familial case of non-syndromic aortic disease.

Background: Non-syndromic aortic disease (NSAD) is a frequently asymptomatic but potentially lethal disease characterised by familial cases of thoracic aortic aneurysms and dissections. This monogenic but genetically heterogeneous condition is primarily inherited as an autosomal dominant disorder with low penetrance and variable expression. Mutations in ACTA2, TGFBR1, TGFBR2, MYH11, SMAD3, MYLK, and FBN1 genes have been described but still, there are many unresolved familial cases.

Stroke echoscan protocol: a fast and accurate pathway to diagnose embolic strokes.

Background And Purpose: Cardiac Echoscan is the simplified transthoracic echocardiogram focused on the main source of emboli detection in the acute stroke diagnosis (Stroke Echoscan). We describe the clinical impact related to the Stroke Echoscan protocol in our Center.

Methods: Acute stroke patients who underwent the Stroke Echoscan by a trained stroke neurologist were included (Echoscan group).

Imaging aortic aneurysmal disease.

Imaging techniques play a crucial role in the diagnosis, follow-up and management of aortic aneurysms. Ultrasound, CT and MRI have strengths and limitations in the assessment of this disease depending on the aorta segment involved, reason for the study (screening, follow-up or surgical indication) and patient characteristics. Ultrasound, transthoracic or abdominal, is highly useful in the diagnosis and follow-up of proximal ascending aorta and abdominal aorta aneurysms, respectively.

Differential transcript profiles of MHC class Ib(Qa-1, Qa-2, and Qa-10) and Aire genes during the ontogeny of thymus and other tissues.

Qa-2 and Qa-1 are murine nonclassical MHC class I molecules involved in the modulation of immune responses by interacting with T CD8(+) and NK cell inhibitory receptors. During thymic education, the Aire gene imposes the expression of thousands of tissue-related antigens in the thymic medulla, permitting the negative selection events. Aiming to characterize the transcriptional profiles of nonclassical MHC class I genes in spatial-temporal association with the Aire expression, we evaluated the gene expression of H2-Q7(Qa-2), H2-T23(Qa-1), H2-Q10(Qa-10), and Aire during fetal and postnatal development of thymus and other tissues.

Recommendations for transoesophageal echocardiography: EACVI update 2014.

With this document, we update the recommendations for transoesophageal echocardiography (TOE) of the European Association of Cardiovascular Imaging. The document focusses on the areas of interventional TOE, in particular transcatheter aortic, mitral, and left atrial appendage interventions, as well as on the role of TOE in infective endocarditis, adult congenital heart disease, and aortic disease.

Public and private pregnancy care in Reggio Emilia Province: an observational study on appropriateness of care and delivery outcomes.

Background: In industrialized countries, improvements have been made in both maternal and newborn health. While attention to antenatal care is increasing, excessive medicalization is also becoming more common.The aim of this study is to compare caesarean section (CS) frequency and ultrasound scan utilization in a public model of care involving both midwives and obstetricians with a private model in which care is provided by obstetricians only.

MicroRNA expression profiling and functional annotation analysis of their targets in patients with type 1 diabetes mellitus.

Type 1 diabetes mellitus (T1DM) results from an autoimmune attack against the insulin-producing pancreatic β-cells, leading to elimination of insulin production. The exact cause of this disorder is still unclear. Although the differential expression of microRNAs (miRNAs), small non-coding RNAs that control gene expression in a post-transcriptional manner, has been identified in many diseases, including T1DM, only scarce information exists concerning miRNA expression profile in T1DM.

Second primary malignancies with lenalidomide therapy for newly diagnosed myeloma: a meta-analysis of individual patient data.

Background: Lenalidomide has been linked to second primary malignancies in myeloma. We aimed to pool and analyse available data to compare the incidence of second primary malignancies in patients with and without lenalidomide exposure.

Methods: We identified relevant studies through a search of PubMed and abstracts from the American Society of Clinical Oncology, American Society of Hematology, and the International Myeloma Workshop.

[Care management for tuberculosis: from education to the nurse practice].

S-nitrosylation of TRIM72 at cysteine 144 is critical for protection against oxidation-induced protein degradation and cell death.

Oxidative stress and membrane damage following myocardial ischemia/reperfusion injury are important contributors to cardiomyocyte death and the loss of myocardial function. Our previous study identified cysteine 144 (C144) of tripartite motif-containing protein 72 (TRIM72) as a potential site for S-nitrosylation (SNO). TRIM72 is a cardioprotective membrane repair protein that can be both activated and targeted for degradation by different oxidative modifications.

Tumours of the thymus: a cohort study of prognostic factors from the European Society of Thoracic Surgeons database.

Objectives: A retrospective database was developed by the European Society of Thoracic Surgeons, collecting patients submitted to surgery for thymic tumours to analyse clinico-pathological prognostic predictors.
