Mid-term outcomes of the fenestration, branched stent-graft, and hybrid techniques in the treatment of thoracic aortic pathologies involving the left subclavian artery.

Objective: To compare the midterm outcomes of fenestration, branched stent-graft thoracic endovascular aortic repair, and hybrid procedures in treating aortic arch pathologies involving the left subclavian artery.

Methods: We collected the clinical data from 144 patients with aortic arch pathologies involving and only involving the left subclavian artery (LSA) who underwent fenestration, branched stent-graft thoracic endovascular aortic repair, and hybrid procedures from November 2015 and December 2022 at a single center. Among the patients, 68 were treated by fenestration, 61 by branched stent-grafts, and 15 by hybrid surgery.

MiR-506 Promotes Antitumor Immune Response in Pancreatic Cancer by Reprogramming Tumor-Associated Macrophages toward an M1 Phenotype.

Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant cancer with a poor prognosis, and effective treatments for PDAC are lacking. In this study, we hypothesized that miR-506 promotes antitumor immune response in PDAC by reprogramming tumor-associated macrophages toward an M1 phenotype to reverse its immunosuppressive tumor microenvironment (TME). First, the relationship between TME and the expression of miR-506 was assessed using clinical samples.

Crosstalk between autophagy and immune cell infiltration in the tumor microenvironment.

Autophagy is a conserved process for self-degradation and provides cells with a rescue mechanism to respond to circumstances such as stress and starvation. The role of autophagy in cancer is extremely complex and often paradoxical. Most of the related published studies on tumors are always focused on cancer cells.

IGFBP2 Drives Regulatory T Cell Differentiation through STAT3/IDO Signaling Pathway in Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC) represents one of the deadliest malignancies. Elevated regulatory T cell (Treg) infiltration has a potent immunosuppressive function in tumor biology, which contributes to low survival in PDAC. Nonetheless, the crosstalk between malignant cells and tumor-infiltrating Tregs in PDAC is not well understood.

Mid-term Outcomes of Endovascular and Hybrid Procedures to Treat Complex Aortic Arch Pathologies.

Purpose: To compare the mid-term outcomes of endovascular and hybrid procedures in treating aortic arch pathologies with an unfavorable proximal landing zone, and analyze the different indications of the 2 methods.

Methods: We collected the clinical data from 59 patients with complex aortic arch pathologies who underwent endovascular or hybrid surgery from March 2018 to April 2020 at a single center. Among the patients, 45 were treated by branched or fenestrated surgery and 14 by hybrid surgery.

Transport and retention of bacteria through a filtration system consisting of sands and geotextiles.

Water-saturated column experiments were conducted to study the effect of nonwoven geotextiles on bacteria transport and deposition through two sandy porous media with grain sizes 1.05 and 3.25 mm.

One-stage supraclavicular hybrid procedure for type B aortic dissection involving three rare anatomical anomalies: a case report and literature review.

Managing type B aortic dissection (TBAD) involving Kommerell's diverticulum (KD), aberrant right subclavian artery (ARSA), and isolated left vertebral artery (ILVA), is extremely challenging. As treatment, we described a one-stage hybrid technique combined with thoracic endovascular aortic repair (TEVAR) with open surgery through a supraclavicular incision. A 57-year-old man with TBAD and the three anomalies successfully underwent hybrid TEVAR.
