Objective: While preoperative anemia is prevalent among surgical patients, its impact on patients undergoing transcarotid artery revascularization (TCAR) remains poorly understood. This study aims to assess the relationship between the severity of preoperative anemia and outcomes following TCAR.
Methods: A retrospective analysis of the Vascular Quality Initiative database (2016-2021) was performed to identify patients who underwent TCAR for carotid stenosis.

Renal artery (RA) anomaly is common and may have significant clinical implications. We present a case of a 29-year-old man in whom the upper two-thirds of the right kidney were supplied by the right internal mammary artery and collateral network. Additionally, the superior left RA had proximal stenosis with a distal aneurysm.

When the suprarenal aorta is involved, the disease is usually confined to the orifices of the visceral vessels without obstruction of the aortic lumen. In rare cases, dense, calcified, exophytic, and amorphous lesions causing severe luminal obstruction, termed coral reef atherosclerosis (CRA) of the suprarenal aorta, may occur.

It represents a challenging clinical entity for both endovascular and open repair owing to potential atheroembolization, increased early morbidity and mortality, and poor long-term survival. Patients may be denied repair owing to its high risks.

Environmental concerns from plastic waste are driving interest in alternative monomers from bio-based sources. Pseudoaromatic dicarboxylic acids are promising alternatives with chemical structures similar to widely used petroleum-based aromatic dicarboxylic acids. However, their use in polyester synthesis has been limited due to production challenges.

This study aimed to investigate the association between pre-operative ambulatory status and outcomes following elective EVAR.
Methods: A retrospective review of the multi-institutional Vascular Quality Initiative database was conducted for all patients who underwent elective infrarenal EVAR from 2009 - 2022.
Background: We evaluate the relationship between the hospital case volume (HCV) and mortality outcomes after open aortic repair (OAR) and endovascular aortic repair (EVAR) of intact (iEVAR) and ruptured (rEVAR) abdominal aortic aneurysm (AAA) using a contemporary administrative database.
Methods: The Healthcare Cost and Utilization Project Database for New York (2016) and New Jersey/Maryland/Florida (2016-2017) were queried using International Classification of Disease-10th edition to identify patients who had undergone OAR and EVAR. The hospitals were categorized into quartiles (Q) per overall (EVAR + OAR) volume, OAR-alone volume and EVAR-alone volume.
Objective: The aim of this study was to demonstrate the safety and effectiveness of a low-profile thoracic endograft (19-23 French) in subjects with blunt traumatic aortic injury.
Methods: A prospective, multicenter study assessed the RelayPro thoracic endograft for the treatment of traumatic aortic injury. Fifty patients were enrolled at 16 centers in the United States between 2017 and 2021.
The clinical and genetic characteristics of SYNGAP1 mutations in Korean pediatric patients are not well understood. We retrospectively analyzed 13 individuals with SYNGAP1 mutations from a longitudinal aspect. Clinical data, genetic profiles, and electroencephalography (EEG) patterns were examined.

Growing evidence underscores the direct involvement of the nuclear factor-erythroid 2-related factor 2 (NRF2) in the development and progression of IBD, along with its associated complications, including colorectal cancer. The NRF2 pathway plays a crucial role in cellular responses to oxidative stress, and dysregulation of this pathway has been implicated in IBD.

When present, it is usually associated with an underlying etiology such as a connective tissue disorder, inflammatory process, or noninflammatory medial degeneration. In the present report, we describe the case of a girl with tuberous sclerosis complex who underwent successful emergency open repair of a symptomatic infrarenal abdominal aortic aneurysm and recurrent type IV thoracoabdominal aortic aneurysm.

Microfold (M) cells, which play a crucial role in the gut immune response against external antigens, are also exploited for the entry of pathogenic bacteria and proteins into the body. However, whether changes in M cells can affect the gut environments and consequently change brain pathologies in AD remains unknown.

Historically, warfarin has been utilized for prosthetic or compromised vein bypasses. Direct-acting oral anticoagulants (DOACs) are increasingly replacing warfarin in this context, but their efficacy in bypass preservation has not been well-studied.

Objective: Prolonged mechanical ventilation (MV) after extensive aortic reconstructive surgery is common. Studies have demonstrated that diaphragm pacing (DP) improves lung function in patients with unilateral diaphragm paralysis. The goal of this study is to determine whether this technology can be applied to complex aortic repair to reduce prolonged MV and other respiratory sequelae.

In this study, we evaluated the impact of nusinersen on the health-related quality of life (HRQoL) of patients with later-onset SMA and the caregiver burden.
Methods: We assessed the changes in HRQoL using the Pediatric Quality of Life Inventory 4.
Objective: Left subclavian artery (LSA)-branched endografts with retrograde inner branch configuration (thoracic branch endoprosthesis [TBE]) offer a complete endovascular solution when LSA preservation is required during zone 2 thoracic endovascular aortic repair. However, the hemodynamic consequences of the TBE have not been well-investigated. We compared near-wall hemodynamic parameters before and after the TBE implantation using computational fluid dynamic simulations.

A commercial system for pDVA exists; however, it is not yet approved by the U.

Here, we report the development of a broad-host-range synthetic sRNA (BHR-sRNA) platform employing the RoxS scaffold and the Hfq chaperone from Bacillus subtilis. BHR-sRNA is tested in 16 bacterial species including commensal, probiotic, pathogenic, and industrial bacteria, with >50% of target gene knockdown achieved in 12 bacterial species.

The aim of this study is to compare outcomes of UTBAD treated medically or with TEVAR in either the acute (1 to 14 days) or subacute period (2 weeks to 3 months).
Methods: Patients with UTBAD between 2007 and 2019 were identified using the TriNetX Network.
Objective: Data regarding the safety and efficacy of paclitaxel (PTX)-coated peripheral arterial devices for femoropopliteal artery (FPA) atherosclerotic disease is derived from studies that mainly evaluated patients with claudication. Outcomes of PTX treatment for patients with chronic limb-threatening ischemia (CLTI) is incompletely defined. This study compares outcome in patients with CLTI treated with and without PTX.
