Renal oxygenation, function and histopathology in an ovine model of heart failure undergoing cardiopulmonary bypass with 48 hours of recovery: a prospective, observational study*

open access: yesAnaesthesia, EarlyView.
Summary Introduction Acute kidney injury is common after cardiac surgery requiring cardiopulmonary bypass, yet preventive strategies are limited. Progress has been hindered by a lack of clinically relevant experimental models incorporating pre‐existing heart disease.

Spectrum of Congenital Malformations in Sex Chromosome Tetrasomies and Pentasomies: A Systematic Review

open access: yesAndrology, EarlyView.
ABSTRACT Sex chromosome aneuploidies represent a heterogeneous group of chromosomal conditions, in which phenotypic complexity generally increases with the number of supernumerary sex chromosomes. While Turner syndrome and sex chromosome trisomies are relatively well characterized, less is known about congenital malformations in sex chromosome ...

The Evolution in Understanding the Physiological Causes of Dyspnoea in Large Hiatal Herniation: A Narrative Review

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Background The symptomatology of large hiatus hernia (LHH) has been historically poorly understood, with cardiorespiratory symptoms caused by LHH being underappreciated by clinicians. This study reports on the mechanisms of dyspnoea in LHH through a historical review of symptoms and evolved physiological literature, discussing likely causation.

Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed‐wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

Geometry‐Related Technical Complications After LVAD Implantation: Impact on Device Dysfunction and Clinical Outcomes

open access: yesArtificial Organs, EarlyView.
Preventable geometric failure modes, such as outflow graft kinking and inflow malposition, frequently cause HeartMate 3 dysfunction. This study identifies these complications as key drivers of device‐related morbidity, highlighting the importance of optimized surgical positioning to ensure long‐term device performance and improved clinical outcomes ...
