Left ventricular elastance with resting volumetric transthoracic echocardiography identifies different phenotypes in heart failure with preserved ejection fraction: A retrospective analysis of a multicenter prospective observational study.

Background: Heart failure with preserved ejection fraction (HFpEF) is a heterogeneous entity including patients with different phenotypes of near normal, normal, and supernormal left ventricular (LV) function.

Objectives: To assess the value of resting LV elastance (also known as force) with transthoracic echocardiography (TTE) to identify HFpEF phenotypes.

Methods: In a prospective, observational, multicenter study, 2380 HFpEF patients were recruited from July 2016 to May 2024.

How Tumors Affect Hemodynamics: A Diffusion Study on the Zebrafish Transplantable Model of Medullary Thyroid Carcinoma by Selective Plane Illumination Microscopy.

Medullary thyroid carcinoma (MTC), a rare neuroendocrine tumor comprising 3-5% of thyroid cancers, arises from calcitonin-producing parafollicular C cells. Despite aggressive behavior, surgery remains the primary curative treatment, with limited efficacy reported for radiotherapy and chemotherapy. Recent efforts have explored the pathogenetic mechanisms of MTC, identifying it as a highly vascularized neoplasm overexpressing pro-angiogenic factors.

A Novel Variant in a Charcot-Marie-Tooth Type 2: Insights from Familial Analysis.

Background/objectives: Axonal Charcot-Marie-Tooth disease type 2 (CMT2) accounts for 24% of Hereditary Motor/Sensory Peripheral Neuropathies.

It is characterized by slowly progressive distal muscle weakness and atrophy, primarily affecting the lower limbs.

[Minimally invasive trans-axillary approach and ultra-fast-track management: a new paradigm for mitral valve disease treatment].

Background: The introduction of transcatheter procedures has focused on patient expectations for treatments with a less invasive approach and faster recovery. The aim of this study was to assess the short- and medium-term results in patients who underwent trans-axillary mitral valve repair with application of the ultra-fast-track protocol.

Methods: Data from 431 patients undergoing isolated trans-axillary mitral valve repair or associated with tricuspid valve treatment between January 2018 and December 2023 were prospectively collected.

Peripheral airways dysfunction measured by oscillometry differentiates asthma from inducible laryngeal obstruction.

Background: Inducible laryngeal obstruction (ILO, also called vocal cord dysfunction) can be difficult to distinguish clinically from asthma. Limited studies have explored the use of respiratory oscillometry to detect changes unique to ILO, but more study is needed to determine if routine oscillometry can differentiate these two clinical entities.

Objective: Determine if impedance variables measured on routine oscillometry over tidal breathing vary between individuals with asthma and ILO.

Thiolated Cyanines Appended to Partially Pegylated Gold Nanoparticles for Fluorescence Quenching of Two-Channel Photothermal Inks.

Following a new approach, we prepared a nanoink with two separate photothermally responsive absorption bands. One is the localized surface plasmon resonance (LSPR) absorption of gold nanoparticles (AuNP, d=17 nm), the second is the absorption band of two cyanine (Cy) dyes, Cy7-C6 or Cy7-C11, grafted to the AuNP surface through thiolated bridges of different lengths: the close proximity to the Au surface induces full quenching of the Cy fluorescence, resulting in thermal relaxation on irradiation. Attempts to full coat AuNP with the lipophilic Cy7-C6 and Cy7-C11 lead to precipitation from aqueous solutions.

Experiences of a Digital Mental Health Intervention from the Perspectives of Young People Recovering from First-Episode Psychosis: A Focus Group Study.

Unlabelled: Horyzons is a digital health intervention designed to support recovery in young people receiving specialized early intervention services for first-episode psychosis (FEP). Horyzons was developed in Australia and adapted for implementation in Canada based on input from clinicians and patients (Horyzons-Canada Phase 1) and subsequently pilot-tested with 20 young people with FEP (Horyzons-Canada Phase 2).

Objective: To understand the experiences of young adults with FEP who participated in the pilot study based on focus group data.

Digital health innovation to prevent relapse and support recovery in young people with first-episode psychosis: A pilot study of Horyzons-Canada.

Digital health innovations may help to improve access to psychosocial therapy and peer support; however, the existence of evidence-based digital health interventions for individuals recovering from a first-episode psychosis (FEP) remains limited. This study aims to investigate the feasibility, acceptability, safety, and pre-post outcomes of Horyzons-Canada (HoryzonsCa), a Canadian adaptation of a digital mental health intervention consisting of psychosocial interventions, online social networking, and clinical and peer support moderation. Using a convergent mixed-methods research design, we recruited participants from a specialized early intervention clinic for FEP in Montreal, Canada.
