An Echocardiographic Study of a Rare Cause of Mitral Regurgitation: Hypoplastic Posterior Mitral Valve Leaflet.

Background: The precise etiology of hypoplasia of the posterior mitral valve leaflet (PMVL) remains incompletely elucidated; however, it has been hypothesized to stem from genetic mutations occurring during fetal development. Herein, we present the anatomical characteristics of the mitral valve and associated cardiac pathologies in patients with hypoplastic PMVL.

Methods: This single-center retrospective study involved patients who presented between 2015 and 2021 at a tertiary healthcare facility.

Examination of optical coherence tomography findings in patients with pregabalin use disorder.

Background: Pregabalin abuse is a rapidly growing health problem worldwide, and little is known about the effects of prolonged high-dose use in patients with pregabalin use disorder.

Objective: In this study, the effects of pregabalin abuse on retinal layers were investigated in patients with pregabalin use disorder (PGUD).

Methods: This study included 35 controls and 34 patients with PGUD, according to Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 criteria.

Multimodality Imaging in Cardiomyopathies.

Cardiomyopathy, which is shortly defined as a disease of the myocardium, has a broad definition that includes many different diagnoses. Recent advances in cardiac imaging techniques, including basic and advanced echocardiography, computed tomography, nuclear medicine, and cardiac magnetic resonance, allow for a more accurate evaluation of volumes and thickness of cardiac chambers, systolic and diastolic function of the ventricules, and tissue structure. Multimodality imaging often provides the first clinical suspicion for specific etiologies, especially when the medical and family history is unclear, by identification of red flags of underlying systemic diseases.

Difficulties in emotion regulation and attachment styles among Kurdish individuals in Eastern Turkey with substances use disorders.

The aim of this study was to investigate the relationship between attachment style and emotion dysregulation in Kurdish individuals with substance use disorders (SUDs) in Eastern Turkey, a non-Western, Islamic society, in a descriptive cross-sectional design. This study was conducted with 216 individuals with SUDs who were treated at the SBU Van Training and Research Hospital Alcohol and Substance Addiction Treatment Center in Eastern Turkey between April 2023 and June 2023. Almost half of the participants (44.

THE effect of P2X7 receptor activation on functional responses of human left internal mammary artery.

The Purinoreceptor 7 (P2X7R) has become a promising drug target in many cardiovascular diseases, including coronary artery disease, since prolonged activation of P2X7R could promote vascular dysfunction, atherosclerosis, and thrombosis. Thus, we aimed to study the effects of P2X7R activation on vascular relaxation responses of the human left internal mammary artery (LIMA). Sections of redundant human LIMA were cut into 3-mm wide rings,, suspended in 20-mL organ baths containing physiologic salt solution, and attached to an isometric force transducer connected to a computer-based data acquisition system.
