Biodegradation Behavior of Neat PLA Fibers Under Controlled Industrial Composting Conditions: Fiber Characterization and Physical Changes During the Composting Process

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Poly(lactic) acid (PLA) biodegradability in fiber form is relatively unexplored. This study shows that the drawing of the fibers during production affects the mechanical properties but slows down the biodegradation of the PLA. Biodegraded undrawn fibers showed peeling whereas drawn fibers showed crack formation on the surface.

Baseline MDCT findings after prosthetic heart valve implantation provide important complementary information to echocardiography for follow-up purposes [PDF]

, 2016
Objectives: Recent studies have proposed additional multidetector-row CT (MDCT) for prosthetic heart valve (PHV) dysfunction. References to discriminate physiological from pathological conditions early after implantation are lacking.

Recurrent Laryngeal Nerve Stretching in Tracheal Diverticulum: First Documented Mechanism of Hoarseness and Systematic Review of Literatures

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Tracheal diverticulum is a rare paratracheal air cyst. It is often asymptomatic. Large symptomatic cases may compress the recurrent laryngeal nerve (RLN) and cause hoarseness. It is a rare presentation, in < 0.2 cases per year in the world.

Coronary CT Angiography and 5-Year Risk of Myocardial Infarction. [PDF]

, 2018
BACKGROUND: Although coronary computed tomographic angiography (CTA) improves diagnostic certainty in the assessment of patients with stable chest pain, its effect on 5-year clinical outcomes is unknown.

Severe Supravalvular Aortic Stenosis Treated With Double Patch Aortoplasty: A Case Report

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Severe supravalvular aortic stenosis in a young patient is a rare but critical condition requiring timely diagnosis and intervention. We report a 15‐year‐old girl presenting with exertional dyspnea, chest pain, and palpitations. Echocardiography and multidetector computed tomography (MDCT) confirmed severe supravalvular aortic stenosis ...

A Novel Multiparametric Model Integrating Aortoseptal Angle to Predict the Origin of Outflow Tract Ventricular Arrhythmias

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
The aortoseptal angle (cutoff 131.24°) effectively differentiates ventricular arrhythmia originating from the left ventricular outflow tract (LVOT). Combining the aortoseptal angle with the hypertension status and V2 transition ratio significantly improves its diagnostic accuracy.
