Article Synopsis
  • The study investigates the effectiveness of amide proton transfer-weighted imaging (APTwi) for differentiating between brain tumors and tumor mimics in a clinical setting, analyzing data from 156 patients.
  • Results revealed that the APT signal intensity (APT-SI) is significantly higher in tumors compared to tumor mimics, particularly in high-grade gliomas and specific tumor subtypes like mesenchymal tumors.
  • The findings suggest that while high APT-SI is more common in aggressive tumors, it can also appear in certain low-grade tumors and tumor mimics, indicating a potential limitation in using APTwi as a definitive diagnostic tool.

Background: Electrocardiographic screening before subcutaneous implantable cardioverter-defibrillator (S-ICD) implantation is unsuccessful in around 10% of cases. A personalized screening method, by slightly moving the electrodes, to obtain a better R/T ratio has been described to overcome traditional screening failure.

Objective: The objectives of the SIS study were to assess to what extent a personalized screening method improves eligibility for S-ICD implantation and to evaluate the inappropriate shock rate after such screening success.

Apico-aortic conduit: a readily available technical modification.

Eur J Cardiothorac Surg

May 2024

Department of Thoracic, Cardiac and Vascular Surgery, University Hospital Pontchaillou, Rennes, France.

When neither surgical valve replacement nor transcatheter aortic valve implantation is possible, performing an apico-aortic conduit remains a therapeutic option. This procedure has become rare and the rigid angled apical connectors usually used to facilitate ventricular anastomosis are no longer commercially available. We described the technique that we performed on a 60-year-old patient with readily available material.

Background/introduction: Currently, despite continued issues with durability ( 1), biological prosthetic valves are increasingly chosen over mechanical valves for surgical aortic valve replacement (SAVR) in adult patients of all ages, at least in Western countries. For younger patients, this choice means assuming the risks associated with a redo SAVR or valve-in-valve procedure.

Purpose: To assess the use of mechanical vs.

Excellent outcomes of angioplasty/stenting for the post-thrombotic syndrome (PTS) have been reported, notably regarding objective criteria in the vast French SFICV cohort. Differences may exist between patient-reported and objective outcomes. We investigated this possibility by using validated scales because significative correlations are discordant in the literature between patency and patient-reported characteristics.

Aims: While elevated resting heart rate measured at a single point of time has been associated with cardiovascular outcomes, utility of continuous monitoring of nocturnal heart rate (NHR) has never been evaluated. We hypothesized that dynamic NHR changes may predict, at short term, impending cardiovascular events in patients equipped with a wearable cardioverter-defibrillator (WCD).

Methods And Results: The WEARIT-France prospective cohort study enrolled heart failure patients with WCD between 2014 and 2018.

Article Synopsis
  • Heart failure (HF) and arrhythmia-related complications significantly impact patients with nonischemic dilated cardiomyopathy (NIDCM), and this study investigates the prognostic value of cardiovascular magnetic resonance (CMR) imaging metrics like T1 and extracellular volume (ECV) for predicting these events.
  • Analyzing 225 NIDCM patients over two years, the study found 26% experienced major adverse cardiovascular events (MACE), with a notable association between increased ECV and HF-related events, while higher T1 Z-scores and ECV values correlated with arrhythmia-related events.
  • The study concluded that specific cutoffs for ECV and T1 Z-scores can be important independent predictors of both

Cardiac screening before returning to elite sport after SARS-CoV-2 infection.

Arch Cardiovasc Dis

November 2022

Cardiology Department, Clinique du Millénaire, Montpellier, France.

Article Synopsis
  • A study evaluated cardiac health in elite athletes post-SARS-CoV-2 infection to understand the risks before returning to play.* -
  • Among 554 athletes screened, only a few showed potential abnormalities linked to the virus, with very low rates of findings from ECGs, echocardiograms, and exercise tests.* -
  • The results suggest that systematic cardiac evaluations may not be necessary for athletes recovering from non-hospitalized SARS-CoV-2 infection, as serious cardiac issues were rare.*

Most of the organs of the digestive tract comprise secretory epithelia that require specialized molecular machines to achieve their functions. As such anterior gradient (AGR) proteins, which comprise AGR1, AGR2, and AGR3, belong to the protein disulfide isomerase family, and are involved in secretory and transmembrane protein biogenesis in the endoplasmic reticulum. They are generally expressed in epithelial cells with high levels in most of the digestive tract epithelia.

The Hippo pathway effector YAP is dysregulated in malignant pleural mesothelioma (MPM). YAP's target genes include the secreted growth factor amphiregulin (AREG), which is overexpressed in a wide range of epithelial cancers and plays an elusive role in MPM. We assayed the expression of YAP and AREG in MPM pathology samples and that of AREG additionally in plasma samples of patients from the randomized phase 3 IFCT-0701 Mesothelioma Avastin Cisplatin Pemetrexed Study (MAPS) using immunohistochemistry and ELISA assays, respectively.

Background: The association between the use of potentially nephrotoxic drugs [Non-Steroidal Anti-Inflammatory Drugs (NSAIDs), Iodinated Contrast Agents, Proton Pump Inhibitors (PPIs)] and emergency start of dialysis in patients with chronic kidney disease has not been well explored, although these compounds are commonly prescribed or available without prescription.

Methods: In this study, the Renal Epidemiology Information Network (REIN) registry data of all patients ≥ 18 years of age who started dialysis in France in 2015 were matched with those in the French National Health Insurance Database. The association between clinical characteristics, nephrotoxic drug exposure and emergency dialysis start was investigated.
