Is Traumatic Anterior Stove-In Chest Truly so Rare? A Single Institution Experience.

Introduction: The anterior stove-in chest (ASIC) is a rare form of flail chest involving bilateral rib or sternal fractures resulting in an unstable chest wall that caves into the thoracic cavity. Given ASIC has only been described in a handful of case reports, this study sought to review our institution's experience in the surgical management of ASIC injuries.

Methods: A retrospective review of patients with ASIC was conducted at our level I trauma center from 1//2021 to 3//2023.

Bullet Embolism into the Common Iliac Artery from a Gunshot Wound to the Heart.

We describe the management of bullet embolism from a penetrating cardiac injury, including the clinical, radiographic, and operative considerations in this challenging trauma scenario. Bullet embolism represents a rare but complex subset of ballistic penetrating trauma, and highlights the importance of radiographic correlation with intraoperative findings.

Pim1 maintains telomere length in mouse cardiomyocytes by inhibiting TGFβ signalling.

Aims: Telomere attrition in cardiomyocytes is associated with decreased contractility, cellular senescence, and up-regulation of proapoptotic transcription factors. Pim1 is a cardioprotective kinase that antagonizes the aging phenotype of cardiomyocytes and delays cellular senescence by maintaining telomere length, but the mechanism remains unknown. Another pathway responsible for regulating telomere length is the transforming growth factor beta (TGFβ) signalling pathway where inhibiting TGFβ signalling maintains telomere length.
