Impact of Laparoscopic Sleeve Gastrectomy on Pulmonary Arterial Stiffness and Right Ventricular Function in Obese Patients.

Introduction: Pulmonary hypertension (PH) is a serious condition associated with high morbidity and mortality, with obesity identified as a significant risk factor. Pulmonary arterial stiffness (PAS) is an early marker of PH, often preceding clinical symptoms. While laparoscopic sleeve gastrectomy (LSG) has been shown to improve various cardiac parameters in obese patients, its impact on PAS and right ventricular (RV) function in the absence of PH remains unclear.

The effects of combination treatment with LT4 and LT3 on diastolic functions and atrial conduction time in LT4-treated women with low T3: a short term follow-up study.

Purpose: To investigate the effects of combination treatment with levothyroxine (LT4) and l- triiodothyronine (LT3) on left atrial volume (LAV), diastolic functions, and atrial electro-mechanical delays in LT4-treated women with low triiodothyronine (T3) levels.

Methods: This prospective study consisted of 47 female patients between 18 and 65 years old treated at an Endocrinology and Metabolism outpatient clinic between February and April 2022 due to primary hypothyroidism. The study included patients with persistently low T3 levels in at least three measurements, despite LT4 treatment (1.

Assessment of Pulmonary Pulse Transit Time with Respect to Diastolic and Left Atrial Functions.

Background And Aim: Pulmonary pulse transit time (pPTT) is a new marker of pulmonary hypertension (PH), which shows the time needed for the pulse wave to propagate from the right ventricular outflow tract to the left atrium (LA), but the relationship between pPTT and diastolic-LA function is almost unknown. In this study, we investigated the relationship between pPTT and LA-diastolic functions without PH.

Materials And Methods: One hundred and fifty-six patients were included in this prospectively designed study.

Comparison of Serum Mitochondrial Open Reading Frame of the 12S rRNA-c (MOTS-c) Levels in Patients With Multiple Sclerosis and Healthy Controls.

Background Multiple sclerosis (MS) is a major global problem, and as its pathogenesis is understood more clearly, therapeutic options expand accordingly. The mitochondrial open reading frame of the 12S rRNA-c (MOTS-c) is a novel mitochondria-derived protein acting on metabolic homeostasis. In this study, we aimed to investigate the role of serum MOTS-c in the pathophysiology of the disease in MS patients and to discuss the mechanism of MOTS-c.

Association of Epicardial Fat Tissue with Coronary Artery Disease and Left Ventricle Diastolic Function Indicators.

BACKGROUND Epicardial fat tissue (EAT) acts as brown adipose tissue and protects the heart and coronary arteries against hypothermia. Recent studies demonstrated that EAT is a source of both anti-inflammatory and atherogenic cytokines. In this study, our aim was to investigate the association of vertical, horizontal, and area measurements of EAT thickness and their association with coronary artery disease, diastolic function, and myocardial performance index in patients who underwent coronary angiography.
