RibMR - A Mixed Reality Visualization System for Rib Fracture Localization in Surgical Stabilization of Rib Fractures: Phantom, Preclinical, and Clinical Studies.

In surgical stabilization of rib fractures (SSRF), the current standard relies on preoperative CT imaging and often incorporates ultrasound (US) imaging. As an alternative, mixed reality (MR) technology holds promise for improving rib fracture localization. This study presents an MR-based visualization system designed for SSRF in a clinical setting.

Exploring the Performance of Geometry-Based Markerless Registration in a Simulated Surgical Environment: A Comparative Study of Registration Algorithms in Medical Augmented Reality.

Augmented Reality (AR) has been utilized in multiple applications in the medical field, such as augmenting Computed Tomography (CT) images onto the patient's body during surgery. However, one of the challenges in its utilization is to register the pre-operative CT images to the patient's body accurately. The current registration process requires prior attachment of tracking markers, and their localization within the body and CT images.

Thrombolysis of bowel obstruction? A thought-provoking presentation of a common surgical pathology.

We present a unique case of bowel obstruction with a hiatus hernia causing atypical chest pain with dynamic ST-segment elevation in a regional Australian emergency department. The ST elevation only resolved after nasogastric decompression of the bowel obstruction. Early thrombolysis of presumed myocardial infarction led to upper gastrointestinal tract bleeding that could have been avoided with timely diagnosis.

Predicting morbidity and mortality in Australian paediatric trauma with the Paediatric Age-Adjusted Shock Index and Glasgow Coma Scale.

Background: Paediatric age-adjusted shock index (SIPA) has emerged as a predictor of morbidity and mortality in trauma. Poor sensitivity and low generalisability demonstrated in previous studies have limited its use. We evaluate the use of SIPA in the general Australian paediatric trauma population and the combination of SIPA with GCS.

Novel arterioplasty of severe left pulmonary artery stenosis using native main pulmonary artery.

There are multiple approaches described for the repair of stenosed branch pulmonary arteries. Regardless of the technique used, restenosis is common. We describe a case of severe left pulmonary artery stenosis repaired with a novel technique using the native main pulmonary artery which was transected and turned down to create a direct anastomosis with the left pulmonary artery.

One stage combined repair of intracardiac defects with vascular ring employing sternotomy approach.

We present an unusual case of atrial septal defect and ventricular septal defect with a vascular ring formed by a right-sided aortic arch with an aberrant left subclavian artery that gave rise to a patent ductus arteriosus connecting to the main pulmonary artery. We performed a single-stage repair of the intracardiac defects and division of vascular ring with a sternotomy instead of the traditionally practiced dual approach. This included division and reimplantation of the aberrant left subclavian artery to the left carotid artery after transection.

Epigenetic aging in newborns: role of maternal diet.

Background: Epigenetic aging is associated with higher risk of cardiovascular disease, cancer, and all-cause mortality and may be a mechanistic link between early-life exposures, such as maternal dietary characteristics during pregnancy, and risk of adult disease.

Objectives: We sought to determine the early-life risk factors for newborn epigenetic aging, specifically maternal dietary macronutrient intake, and whether epigenetic aging is associated with cardiovascular health markers in the newborn.

Methods: Epigenetic age acceleration of 169 newborns was measured from saliva using the Horvath age calculator.
