RESUMEN

BACKGROUND: Blunt traumatic aortic injury (BTAI) is a rare occurrence in adolescents, yet it is associated with a high mortality rate necessitating immediate treatment. Although endovascular repair has become the preferred treatment for such injuries in adults, its effectiveness in adolescents remains uncertain. CASE SUMMARY: Blunt traumatic aortic injury typically presents with concomitant injuries to other organs and carries a high perioperative mortality rate with operative repair (OR). In this report, we describe the treatment of 3 clinical cases of BTAI in adolescents using thoracic endovascular aortic repair (TEVAR). These cases contribute pertinent evidence supporting the efficacy of intravascular repair for BTAI. CONCLUSION: Operative repair (OR) remains the gold standard for treating BTAI in adolescents. Nevertheless, TEVAR therapy presents a viable alternative for patients with multiple injuries in whom anticoagulation is contraindicated. Further long-term observation is necessary to assess the lasting effects of TEVAR therapy. CLINICAL IMPACT: This study has provided insights into endovascular repair for adolescent BTAT, offering clinicians significant reference material for choosing treatment strategies for adolescent BTAT. The study aims to demonstrate the safety and effectiveness of endovascular repair treatments in a series of clinical cases involving adolescent BTAI.

RESUMEN

One means by which cells reutilize neutral lipids stored in lipid droplets is to degrade them by autophagy. This process involves spartin, mutations of which cause the rare inherited disorder Troyer syndrome (or spastic paraplegia-20, SPG20). A recently published paper from the team led by Karin Reinsich (Yale) suggests that the molecular function of spartin and its unique highly conserved "senescence" domain is as a lipid transfer protein. Spartin binds to and transfers all lipid species found in lipid droplets, from phospholipids to triglycerides and sterol esters. This lipid transfer activity correlates with spartin's ability to sustain lipid droplet turnover. The senescence domain poses an intriguing question around the wide range of its cargoes, but intriguingly it has yet to yield up its secrets because attempts at crystallization failed and AlphaFold's prediction is unconvincing.
