There is a lack of medical simulation tools that can be understood and used, at the same time, by researchers, teachers, clinicians and students. Regarding this issue, in this work we report a virtual simulator (developed in OpenModelica) that allow to experiment with the fundamental variables of the cardiovascular and respiratory system of a neonate. We extended a long-tested lumped parameter model that represents the cardiovascular and respiratory physiology of a neonate. From this model, we implemented a physiological simulator using Modelica. The fidelity and versatility of the reported simulator were evaluated by simulating seven physiological scenarios: two of them representing a healthy infant (newborn and 6-months old) and five representing newborns affected by different heart diseases. The simulator properly and consistently represented the quantitative and qualitative behaviour of the seven physiological scenarios when compared with existing clinical data. Results allow us to consider the simulator reported here as a reliable tool for researching, training and learning. The advanced modelling features of Modelica and the friendly graphical user interface of OpenModelica make the simulator suitable to be used by a broad community of users. Furthermore, it can be easily extended to simulate many clinical scenarios.

Yes-associated protein (YAP) plays a central role in the Hippo pathway, primarily governing cell proliferation, differentiation, and apoptosis. Its significance extends to tumorigenesis and inflammatory conditions, impacting disease initiation and progression. Given the increasing relevance of YAP in inflammatory disorders and cancer, this study aims to elucidate its pathological regulatory functions in these contexts.

Background: In 2023, collaboration between cardiologists and oncologists was recommended as part of Japan's Basic Plan to Promote Disease Control Programs for both cancer and cardiovascular diseases. This study explores the extent of this collaboration in Niigata Prefecture.
Methods And Results: Self-administered questionnaires about immune checkpoint inhibitor-associated myocarditis (ICIAM) and anthracycline-related cardiomyopathy (ARCM) were distributed to all cardiologists and leading oncologists in hospitals across the Prefecture, of whom 124 cardiologists and 41 oncologists across 29 hospitals responded.

Respiratory diseases rank among the foremost causes of mortality and disability globally, with long-term exposure to environmental pollutants playing a critical role in their onset and progression. Despite this, the underlying mechanisms and effective targeted treatments for these disorders remain poorly understood, highlighting an urgent need for focused research. Cell death, a programmed cellular response to external harmful stimuli, including ferroptosis-a recently identified form of iron-dependent programmed cell death-emerges as a pivotal process.

Aims: 4D flow magnetic resonance imaging (MRI) has enabled evaluation of intracardiac flow dynamics by particle tracing for visualizing and quantifying complex flow patterns. The aim of this study was to assess the impact of respiratory motion compensation on 4D flow MRI-based left ventricular four-component particle tracing, valve tracking, and haemodynamics.
Methods And Results: In this prospective cohort study, 4D flow MRI with and without respiratory motion compensation was performed in 15 healthy volunteers.
