The Inequitable Experiences of Left-Handed Medical Students in Surgical Education.

Purpose: Left-handed medical students contend with unique educational barriers within surgery, such as lack of educational resources, lack of left-handed-specific training, and widespread stigmatization of surgical left-handedness. This study aimed to highlight the surgical experiences of left-handed medical students so educators may be empowered to act with greater care and appreciation of these students' circumstances.

Method: In this qualitative study, the authors conducted semistructured interviews on surgical experiences during medical school between January 31, 2021, and June 20, 2021, on 31 current surgical residents and fellows from 15 U.

Natural history of visceral branch artery dissections and the influence of concurrent aortic dissection on overall and intervention-free survival.

Objective: Visceral branch artery dissection (VBAD) is uncommon and may occur with or without an associated aortic dissection (AD). We hypothesized that isolated VBAD would have a more benign clinical course than those with concurrent AD and compared survival outcomes stratified based on aortic involvement.

Methods: VBAD over a 5-year period were identified using International Classification of Diseases codes.

Use of Direct Oral Anticoagulant and Associated Bleeding and Thrombotic Complication after Lower Extremity Bypass.

Background: Therapeutic anticoagulation with either a vitamin K antagonist (VKA) or direct anticoagulant (DOAC) is often newly prescribed to patients undergoing lower extremity bypass (LEB) to aid in graft patency when risk factors for thrombosis are present or to treat postoperative venous thromboembolism or atrial fibrillation. There is a gap in knowledge as to how DOAC usage impacts postoperative outcomes compared with the standard-of-care VKAs.

Study Design: To determine temporal trends in DOAC prescription after infrainguinal LEB, impact on length of stay (LOS), and associated bleeding and thrombotic complications, patients undergoing elective LEB were identified from the Vascular Quality Initiative between January 2013 and May 2019.

Characterizing patient-reported claudication treatment goals to support patient-centered treatment selection and measurement strategies.

Objective: Patient-reported outcomes (PRO) have been increasingly emphasized for peripheral artery disease (PAD). Patient-defined treatment goals and expectations, however, are poorly understood and might not be achievable or aligned with guidelines or clinical outcomes. We evaluated the patient-reported treatment goals among patients with claudication and the associations between patient characteristics, goals, and PAD-specific PRO scores.

Focus group study of factors relevant to treatment decisions and experiences among patients with symptomatic peripheral artery disease.

Background: Clinical guidelines recommend shared decision-making for treatment of peripheral artery disease (PAD), which requires understanding of patient perspectives and preferences. We conducted a focus group study of patients with symptomatic PAD to identify factors important and relevant to treatment choices, and to characterize aspects of the health care process that contribute to positive vs negative experiences apart from the specific treatment(s) received.

Methods: Participants were recruited from an academic medical center over 2 years using a purposeful sampling approach based on a clinical diagnosis of symptomatic PAD (either claudication or chronic limb-threatening ischemia [CLTI]) confirmed by the abnormal ankle or toe brachial index.

How We Do It: A Multicenter National Experience of Virtual Vascular Surgery Rotations.

Objective: To describe the development and implementation of virtual vascular surgery rotations among 6 integrated vascular surgery programs.

Design: A collaborative teleconference retrospectively discussing 6 independently developed virtual vascular surgery rotations to make a framework for future use.

Setting: University of California Davis initiated a joint teleconference among the various integrated vascular surgery programs.

Industry Compensation to Physician Vascular Specialist Authors of Highly-referenced Aortic Aneurysm Studies.

Background: Industry payments to physicians may influence their attitudes toward medical devices and products. Disclosure of industry compensation by authors of scientific manuscripts usually occurs at the authors' discretion and is seldom audited as part of the peer review process. The purpose of this analysis was to characterize industry compensation among highly cited research articles related to aortic aneurysm.

Exploring the rapid expansion of office-based laboratories and peripheral vascular interventions across the United States.

Objective: To characterize the relationship between office-based laboratory (OBL) use and Medicare payments for peripheral vascular interventions (PVI).

Methods: Using the Centers for Medicare and Medicaid Services Provider Utilization and Payment Data Public Use Files from 2014 to 2017, we identified providers who performed percutaneous transluminal angioplasty, stent placement, and atherectomy. Procedures were aggregated at the provider and hospital referral region (HRR) level.

Effect of concomitant deep venous reflux on truncal endovenous ablation outcomes in the Vascular Quality Initiative.

Objective: Few studies have investigated outcomes after truncal endovenous ablation in patients with combined deep and superficial reflux and no studies have evaluated patient-reported outcomes.

Methods: We investigated the short- and long-term clinical and patient-reported outcomes among patients with and without deep venous reflux undergoing truncal endovenous ablation from 2015 to 2019 in the Vascular Quality Initiative. Preprocedural and postprocedural comparisons were performed using the t-test, χ, or their nonparametric counterpart when appropriate.

Comparison of unilateral vs bilateral and staged bilateral vs concurrent bilateral truncal endovenous ablation in the Vascular Quality Initiative.

Objective: Venous insufficiency is commonly bilateral, and patients often prefer single-episode care compared with staged procedures. Few studies have investigated clinical outcomes after unilateral vs bilateral venous ablation procedures or between staged and concurrent bilateral procedures. Here, we report data from the Vascular Quality Initiative regarding truncal venous ablation for chronic venous insufficiency.

Aggressive Phenotype of Intravascular Lymphoma Relative to Other Malignant Intraabdominal Tumors Requiring Vascular Reconstruction.

Background: Safe resection of intraabdominal and retroperitoneal malignancies with a goal of negative margins may require vascular surgical assistance with grafting of the aorta and/or vena cava. The current report reviews malignancies associated with major vascular reconstructions at a single tertiary referral center.

Methods: Adults with abdominal or retroperitoneal tumors involving the aorta, vena cava, or iliac arteries that underwent reconstruction with vascular grafts at the University of Michigan from 2010 to 2016 were reviewed retrospectively.

New predictors of complications in carotid body tumor resection.

Objective: This study examined the relationship between two new variables, tumor distance to base of skull (DTBOS) and tumor volume, with complications of carotid body tumor (CBT) resection, including bleeding and cranial nerve injury.

Methods: Patients who underwent CBT resection between 2004 and 2014 were studied using a standardized, multi-institutional database. Demographic, perioperative, and outcomes data were collected.

General Anesthesia Is Not Necessary for Hemodialysis Access Surgery.

Chronic kidney disease has been identified as a risk factor for mortality after procedures under general anesthesia (GA). However, a recent study showed that 85 per cent of arteriovenous fistulas in the United States are performed under GA. Our aim was to demonstrate that GA can be avoided in patients with chronic kidney disease and end-stage renal disease by using local anesthesia (LA) with monitored anesthesia care or brachial plexus block (BPB) during hemodialysis access surgery.

Effects of international health electives on medical student learning and career choice: results of a systematic literature review.

Background And Objectives: The present study reviewed the published literature to examine the effects of international health electives (IHEs) on medical student learning and career choice.

Methods: A systematic literature review was conducted to identify key English-language articles on IHEs, using PubMed journal databases for the period 1990--2009. Article inclusion for this review was vetted by a rigorous evaluation of each article's study methods, content, and data quality.

Differential induction of glioblastoma migration and growth by two forms of pleiotrophin.

Glioblastoma is the most common malignant brain tumor of adults and one of the most lethal cancers. The secreted growth factor pleiotrophin (PTN) promotes glioblastoma migration and proliferation, initiating its oncogenic activities through two cell surface receptors, the protein tyrosine phosphatase receptor zeta (PTPRZ1) and the anaplastic lymphoma kinase (ALK), respectively. Here, we report on the presence and purification of two naturally occurring forms of PTN (18 and 15 kDa) that differentially promote glioblastoma migration and proliferation.
