A 51-year-old man with thoracoabdominal aortic aneurysm (DeBakey IIIb type chronic aortic dissection) first underwent the graft replacement of thoracic aorta with elephant trunk technique. Postoperatively, the residual false lumen just distal to the inserted graft as an elephant trunk enlarged in a short period, and it compressed the esophagus. He underwent the second graft replacement of thoracoabdominal aorta 2 months after the first surgery. Just after the second surgery, he had the esophageal rupture probably because of direct damage due to the enlarged aneurysm and loss of the arterial blood supply due to the graft replacement. He died of bleeding from the distal anastomosis because of the uncontrolled graft infection. It may have to be kept in mind that the esophageal rupture after the graft replacement could be one of the reason of the graft infection when the aortic aneurysm severely compressed the esophagus preoperatively.

Understanding the impact of racism on surgical outcomes in settler nation-states USA and Canada: a protocol for a systematic review and meta-analysis.
BMJ Open

Department of Surgery, Alberta Health Services, Calgary, Alberta, Canada.
Introduction: To improve surgical quality and safety, health systems must prioritise equitable care for surgical patients. Racialised patients experience worse postoperative outcomes when compared with non-racialised surgical patients in settler colonial nation-states. Identifying preventable adverse outcomes for equity-deserving patient populations is an important starting point to begin to address these gaps in care.

Retinal degenerative diseases encompass a diverse range of eye conditions that result in blindness, many due to photoreceptor dysfunction and loss. Regrettably, current clinical treatments are frequently not overly effective. However, photoreceptor transplantation shows promise as a potential therapy for late-stage retinal degenerative diseases.

Graduate School of Public Health, St Luke's International University, Tokyo, Japan.
Background: Recent studies revealed an association between small kidney volume and progression of kidney dysfunction in particular settings such as kidney transplantation and transcatheter aortic valve implantation. We hypothesized that kidney volume was associated with the incidence of kidney-related adverse outcomes such as worsening renal function (WRF) in patients with acute heart failure (AHF).
Methods: This study was a single-center retrospective cohort study.
Educational or Behavioural Interventions to Improve Long-Term Haemodialysis Vascular Access Self-Management: A Systematic Review.
J Ren Care
March 2025
School of Nursing and Midwifery, Griffith University, Brisbane, Queensland, Australia.
Background: Globally, haemodialysis is the most frequent type of kidney replacement therapy and necessitates access to the bloodstream either through a native arteriovenous fistula, arteriovenous graft or central venous catheter. Vascular access complications are a major cause of morbidity and mortality in adults receiving haemodialysis, and effective vascular access self-management is required.
Objective: To examine the effectiveness of educational or behavioural interventions designed to improve self-management of long-term vascular access in adults receiving haemodialysis.
Autotransplantation of a Third Molar to Replace Compromised Molar With the Individual Three-Dimensional Printed Ultrasonic Osteotome: A Case Report.
Case Rep Dent

Department of Endodontics, Hangzhou Stomatology Hospital, Hangzhou, Zhejiang, China.
Tooth autotransplantation is widely used to replace congenitally missing teeth or teeth with irreversible damage. This case report presents a personalized ultrasonic osteotome that enables precise preparation, minimizes bone trauma, enhances the initial stability of the transplanted tooth, and contributes to a favorable prognosis. The procedure is as follows: a 25-year-old female patient presented with a porcelain-fused-to-metal crown on Tooth #19, which had detached due to severe decay, rendering the tooth unsalvageable.
