The effect of disopyramide therapy on functional capacity improvement in patients with obstructive hypertrophic cardiomyopathy.

Background: Hypertrophic cardiomyopathy (HCM) is characterized by left ventricular outflow tract obstruction (LVOTO), leading to symptoms and adverse outcomes. Disopyramide, with its negative inotropic effects, is commonly used to reduce LVOTO in obstructive HCM (HOCM). This study evaluates the impact of disopyramide on functional capacity in HOCM patients.

An Investigation of RNA Methylations with Biophysical Approaches in a Cervical Cancer Cell Model.

RNA methylation adds a second layer of genetic information that dictates the post-transcriptional fate of RNAs. Although various methods exist that enable the analysis of RNA methylation in a site-specific or transcriptome-wide manner, whether biophysical approaches can be employed to such analyses is unexplored. In this study, Fourier-transform infrared (FT-IR) and circular dichroism (CD) spectroscopy are employed to examine the methylation status of both synthetic and cellular RNAs.

Does the Diagnostic Performance of the Pathologist on the Indeterminate Categories of the Bethesda System for Reporting Thyroid Cytopathology Vary between Pediatric and Adult Patients?

Introduction: The objectives of this study were to investigate the variation in the use of indeterminate categories of The Bethesda System for reporting thyroid cytopathology across age groups, particularly focusing on atypia of undetermined significance (AUS) category, and discern the potential role of a bias in pathologist's interpretation when dealing with pediatric patients.

Materials And Methods: To highlight a more refined diagnostic pattern, thyroid fine-needle aspirations reported by a single pathologist over a span of 10 years enrolled to the study. A total of 8,827 cases from patients aged between 2 and 89 were categorized for each decades of ages.

Ongoing assertion of two-dimensional measurements on differentiation type of left ventricular hypertrophy: Focus on inferior vena cava.

Background: Left ventricular hypertrophy (LVH), including hypertensive LVH, hypertrophic cardiomyopathy (HCM) and cardiac amyloidosis (CA), is a commonly encountered condition in cardiology practice, presenting challenges in differential diagnosis. In this study, we aimed to investigate the importance of echocardiographic evaluation of the inferior vena cava (IVC) in distinguishing LVH subtypes including hypertensive LVH, HCM, and CA.

Methods: In this retrospective study, patients with common causes of LVH including hypertensive LVH, HCM, and CA were included.
