Prenatally Diagnosed Cardiac Tumors and Tuberous Sclerosis Complex: A Single-Center Experience.

Background/objectives: Cardiac rhabdomyoma (CR), the most frequently occurring fetal cardiac tumor, is often an early marker of tuberous sclerosis complex (TSC). This study evaluates outcomes of fetuses with prenatally diagnosed cardiac tumors managed at a single tertiary center.

Methods: Medical records of fetuses diagnosed with cardiac tumors between 2009 and 2024 were retrospectively reviewed.

The anatomic repair of recurrent aortic arch obstruction in children and adolescents.

Objective: Surgery for recurrent aortic arch obstruction is highly challenging and publications are rare. The aim of this retrospective, single-center study was to evaluate mortality, complications, and reintervention rate after an anatomic repair.

Methods: Between 1999 and 2022, in total 946 operations on the aortic arch were performed at the Children's Heart Center Linz.

Fundamental equation of state for mixtures of nitrogen, oxygen, and argon based on molecular simulation data.

A fundamental equation of state in terms of the Helmholtz energy is presented for mixtures of nitrogen, oxygen, and argon at any composition. It is expressed in terms of the residual Helmholtz energy and can be used to calculate all thermodynamic equilibrium properties including vapor-liquid equilibria. The parameters of the equations for the pure-fluid and mixture contributions are fitted exclusively to molecular simulation data so that the model has a predictive character.

Impact Of Sensorineural Hearing Loss On Subjective Tinnitus Quality In Patients With Bilateral Tinnitus.

Introduction: Tinnitus is a frequent condition that indicates the sensation of sound in the absence of a corresponding external stimulus and can significantly impair the quality of life. The main risk factor for developing tinnitus is hearing loss. The diagnosis of tinnitus is based on history, assessment of tinnitus severity, clinical examination, and audiological tests.

Influence of repulsion on entropy scaling and density scaling of monatomic fluids.

Entropy scaling is applied to the shear viscosity, self-diffusion coefficient, and thermal conductivity of simple monatomic fluids. An extensive molecular dynamics simulation series is performed to obtain these transport properties and the residual entropy of three potential model classes with variable repulsive exponents: n, 6 Mie (n = 9, 12, 15, and 18), Buckingham's exponential-six (α = 12, 14, 18, and 30), and Tang-Toennies (αT = 4.051, 4.
