Implementation of a novel peer review academy by Surgery and the Association of Women Surgeons.

BACKGROUND: A novel Peer Review Academy was developed as a collaborative effort between the Association of Women Surgeons and the journal Surgery to provide formal training in peer review. We aimed to describe the outcomes of this initiative using a mixed methods approach. METHODS: We developed a year-long curriculum with monthly online didactic sessions. Women surgical trainee mentees were paired 1:1 with rotating women surgical faculty mentors for 3 formal peer review opportunities. We analyzed pre-course and post-course surveys to evaluate mentee perceptions of the academy and assessed changes in mentee review quality over time with blinded scoring of unedited reviews. Semi-structured interviews were conducted upon course completion. RESULTS: Ten women surgical faculty mentors and 10 women surgical trainees from across the United States and Canada successfully completed the Peer Review Academy. There were improvements in the mentees' confidence for all domains of peer review evaluated, including overall confidence in peer review, study novelty, study design, analytic approach, and review formatting (all, P ≤ .02). The mean score of peer review quality increased over time (59.2 ± 10.8 vs 76.5 ± 9.4; P = .02). In semi-structured interviews, important elements were emphasized across the Innovation, Implementation Process, and Individuals Domains, including the values of (1) a comprehensive approach to formal peer review education; (2) mentoring relationships between women faculty and resident surgeons; and (3) increasing diversity in the scientific peer review process. CONCLUSION: Our novel Peer Review Academy was feasible on a national scale, resulting in significant qualitative and quantitative improvements in women surgical trainee skillsets, and has the potential to grow and diversify the existing peer review pool.

Venous Thromboembolism in Exploration Class Human Spaceflight.

INTRODUCTION: A recent finding of a deep venous thrombosis during spaceflight has prompted the need to clarify mechanisms and risks of venous thromboembolism (VTE). In turn, mitigation countermeasures, diagnostic modalities, and treatment options must be explored. The objective of this review was to synthesize current evidence on VTE in spaceflight.METHODS: A literature review was performed from inception to April 2023 pertaining to VTE in the context of spaceflight or ground-based analogs with human participants. PubMed was searched for papers written in English using the terms "spaceflight" or "weightlessness" and "thrombotic" or "embolism" or "thromboembolism" in "venous" or "veins". Papers using cellular or animal models were excluded.RESULTS: There were 63 papers captured; 7 original scientific studies, 3 narrative reviews, 2 systematic reviews, and 3 commentaries discussed VTE in spaceflight. Reference lists were screened. Important themes included: altered venous hemodynamics, increased fibrinogen and coagulation markers, hypoalbuminemia, and immune dysfunction. Additional risk factors may be seen in women, such as the use of oral contraceptives.DISCUSSION: Venous stasis and decreased shear stress secondary to fluid shifts may induce inflammatory changes in the venous system, resulting in endothelial damage and upregulation of the coagulation cascade. Additionally, women in space are subject to physiological factors increasing their VTE risk, such as the use of oral contraceptives, inducing increased blood viscosity and hypoalbuminemia. Efforts should also be placed in optimizing sensitivity and specificity of imaging markers, payload, and training ability, notably the use of vector flow imaging, and improving point-of-testing biomarkers, such as albumin and p-selectin.Levasseur S, Purvis N, Trozzo S, Chung SH, Ades M, Drudi LM.

A mycotic aneurysm of a jejunal branch treated by aneurysmectomy without bowel resection.

Jejunal artery pseudoaneurysms are extremely rare, accounting for <1% of all visceral artery pseudoaneurysms. Fewer than 50 cases were reported in literature during the previous century. This case report describes the case of a 72-year-old man who underwent aneurysmectomy to treat a 21-mm mycotic jejunal artery pseudoaneurysm found in the setting of endocarditis. This pseudoaneurysm was treated with laparotomy, and gentle dissection of the tissues surrounding the pseudoaneurysm was performed before ligation and resection. This allowed for vascular collateral branch preservation, which, thus, avoided concomitant bowel resection. This report highlights the feasibility of this technique.

Barriers to Implementing the Kidney Disease Outcomes Quality Initiative End-Stage Kidney Disease Life Plan Guideline.

OBJECTIVE: The updated 2019 National Kidney Foundation Kidney Disease Outcomes Quality Initiative vascular access guidelines recommend patient-centered, multi-disciplinary construction and regular update of an individualized end-stage kidney disease (ESKD) Life-Plan (LP) for each patient, a dramatic shift from previous recommendations and policy. The objective of this study was to examine barriers and facilitators to implementing the LP among key stakeholders. METHODS: Semi-structured individual interviews were analyzed using inductive and deductive coding. Codes were mapped to relevant domains in the Consolidated Framework for Implementation Research (CFIR). RESULTS: We interviewed 34 participants: 11 patients with end-stage kidney disease, 2 care partners, and 21 clinicians who care for patients with end-stage kidney disease. In both the clinician and the patient/care partner categories, saturation (where no new themes were identified) was reached at 8 participants. We identified significant barriers and facilitators to implementation of the ESKD LP across three CFIR domains: Innovation, Outer setting, and Inner setting. Regarding the Innovation domain, patients and care partners valued the concept of shared decision-making with their care team (CFIR construct: innovation design). However, both clinicians and patients had significant concerns about the complexity of decision-making around kidney substitutes and the ability of patients to digest the overwhelming amount of information needed to effectively participate in creating the LP (innovation complexity). Clinicians expressed concerns regarding the lack of existing evidence base which limits their ability to effectively counsel patients (innovation evidence base) and the implementation costs (innovation cost). Within the Outer Setting, both clinicians and patients were concerned about performance measurement pressure under the existing "Fistula First" policies and had concerns about reimbursement (financing). In the Inner Setting, clinicians and patients stressed the lack of available resources and access to knowledge and information. CONCLUSION: Given the complexity of decision-making around kidney substitutes and vascular access, our findings point to the need for implementation strategies, infrastructure development, and policy change to facilitate ESKD LP development.

Socioeconomic status fails to account for worse outcomes in non-Hispanic black patients undergoing carotid revascularization.

OBJECTIVE: Previous studies have reported an association of Black race with worse carotid revascularization outcomes, but rarely include socioeconomic status as a confounding covariate. We aimed to assess the association of race and ethnicity with in-hospital and long-term outcomes following carotid revascularization before and after accounting for socioeconomic status. METHODS: We identified non-Hispanic Black and non-Hispanic white patients who underwent carotid endarterectomy, transfemoral carotid stenting, or transcarotid artery revascularization between 2003 and 2022 in the Vascular Quality Initiative. Primary outcomes were in-hospital stroke/death and long-term stroke/death. Multivariable logistic regression and Cox proportional hazards models were used to assess the association of race with perioperative and long-term outcomes after adjusting for baseline characteristics using a sequential model approach without and with consideration of Area Deprivation Index (ADI), a validated composite marker of socioeconomic status. RESULTS: Of 201,395 patients, 5.1% (n = 10,195) were non-Hispanic Black, and 94.9% (n = 191,200) were non-Hispanic white. Mean follow-up time was 3.4±0.01 years. A disproportionately high percentage of Black patients were living in more socioeconomically deprived neighborhoods relative to their white counterparts (67.5% vs 54.2%; P < .001). After adjusting for demographic, comorbidity, and disease characteristics, Black race was associated with greater odds of in-hospital (adjusted odds ratio [aOR], 1.24; 95% confidence interval [CI], 1.10-1.40) and long-term stroke/death (adjusted hazard ratio [aHR], 1.13; 95% CI, 1.04-1.23). These associations did not substantially change after additionally adjusting for ADI; Black race was persistently associated with greater odds of in-hospital (aOR, 1.23; 95% CI, 1.09-1.39) and long-term stroke/death (aHR, 1.12; 95% CI, 1.03-1.21). Patients living in the most deprived neighborhoods were at greater risk of long-term stroke/death compared with patients living in the least deprived neighborhoods (aHR, 1.19; 95% CI, 1.05-1.35). CONCLUSIONS: Non-Hispanic Black race is associated with worse in-hospital and long-term outcomes following carotid revascularization despite accounting for neighborhood socioeconomic deprivation. There appears to be unrecognized gaps in care that prevent Black patients from experiencing equitable outcomes following carotid artery revascularization.

Exploring the perception of venous disease within vascular surgery.

BACKGROUND: Biases and gender disparities influence career pathways within medicine, and vascular surgery is no exception. Venous disease comprises an estimated 1% to 3% of total health care expenditures. However, its value among vascular surgeons is poorly understood. This study aims to investigate the factors that influence vascular surgeons' current perceptions of superficial and deep venous disease treatments. METHODS: An anonymous survey was distributed electronically to practicing vascular surgeons in December 2021. The respondents were stratified by gender and practice breakdown. A venous-heavy practice was defined as a practice with venous work comprising ≥25% of the total volume. Changes in practice patterns over the respondent's career were also explored. Descriptive, univariate, and multivariate analyses were performed using STATA (StataCorp). RESULTS: A total of 315 practicing vascular surgeons responded, with 81.5% from the United States. Their mean age was 46.6 ± 9.6 years, and most identified as men (63.3%). The race and ethnicity breakdown was as follows: White (non-Hispanic), 63.0%; Asian or Asian Indian, 17.1%; Hispanic, Latinx, or Spanish, 8.4%; Black, 1.6%; and unknown, 9.9%. The practice settings were academic for 47.0%, private practice for 26.5%, hospital employed for 23.3%, and other for 3.2%. The female respondents were significantly younger (P < .0001), with fewer years in practice (P < .0001) and were more likely to perceive a gender bias within a career encompassing venous disease compared with the male respondents (P = .02). Of the 315 participants, 143 (45.4%) had a venous-heavy practice. No differences were found in age or gender between the venous-heavy and venous-light practices. Those with a venous-heavy practice had significantly more years in practice statistically (P = .02), had sought more venous training after graduation (P < .0001), were more likely to be in private practice (P < .0001), and were more likely to desire a practice change (P = .001) compared with those with a venous-light practice. Overall, 74.3% of respondents indicated that venous work might be less "valued" than arterial work in the field of vascular surgery. On multivariable regression, the predictors for the perception of venous work being less valued were female gender (odds ratio, 2.01; 95% confidence interval, 1.14-4.03) and completion of a vascular surgery fellowship (odds ratio, 2.0; 95% confidence interval, 1.15-3.57). CONCLUSIONS: Vascular surgeons overwhelmingly perceived the management of venous disease to be of less value than that of arterial disease, particularly by women and fellowship-trained vascular surgeons. The prevalence of venous disease, as measured by its proportion of the U.S. healthcare budget, cannot be overstated. Thus, efforts to elevate the importance of chronic venous disease within the scope of vascular surgery practices are essential to ensure patients are provided with appropriate specialty care.

A Systematic Review and Meta-Analysis on Sex-Based Disparities in Patients with Chronic Limb Threatening Ischemia Undergoing Revascularization.

BACKGROUND: This systematic review and meta-analysis sought to describe the prognostic implications of sex on the clinical outcomes of patients undergoing interventions for chronic limb threatening ischemia (CLTI). METHODS: Studies were systematically searched across 7 databases from inception to August 25, 2021 and rerun on October 11, 2022. Studies focusing on patients with CLTI undergoing open surgery, endovascular treatment (EVT), or hybrid procedures were included if sex-based differences were associated with a clinical outcome. Two independent reviewers screened studies for inclusion, extracted data, and assessed risk of bias using the Newcastle-Ottawa scale. Primary outcomes included inpatient mortality, major adverse limb events (MALE), and amputation-free survival (AFS). Meta-analyses were performed using random effects models and reported pooled odds ratio (pOR) and 95% confidence interval (CI). RESULTS: A total of 57 studies were included in the analysis. A meta-analysis of 6 studies demonstrated that female sex was associated with statistically higher inpatient mortality compared to male sex undergoing open surgery or EVT (pOR, 1.17; 95% CI: 1.11-1.23). Female sex also demonstrated a trend toward increased limb loss in those undergoing EVT (pOR, 1.15; 95% CI: 0.91-1.45) and open surgery (pOR 1.46; 95% CI: 0.84-2.55). Female sex also had a trend toward higher MALE (pOR, 1.06; 95% CI, 0.92-1.21) in 6 studies. Finally, female sex had a trend toward worse AFS (pOR, 0.85; 95% CI, 0.70-1.03) in 8 studies. CONCLUSIONS: Female sex was significantly associated with higher inpatient mortality and a trend toward higher MALE following revascularization. Female sex trended toward worse AFS. The reasons for these disparities are likely multifaceted on patient, provider, and systemic levels and should be explored to identify solutions for decreasing these health inequities across this vulnerable patient population.

Treating a Large Thoracoabdominal Aneurysm With Aberrant Right Subclavian Artery With a Physician-Modified Graft.

CLINICAL IMPACT: Large thoracoabdominal aortic aneurysms due to chronic aortic dissection in patients with connective tissue disorders such as Loeys-Dietz syndrome present a challenging scenario, particularly in cases of variant anatomy and when patients are not candidates for conventional open repair. We demonstrate how by combining and modifying off-the-shelf devices during a hybrid procedure, one can create an endovascular solution tailored to the patient's complex anatomy, making use of an aberrant right subclavian artery, and allow for good clinical outcomes.

Community-engaged research in vascular surgery: An approach to decrease amputation disparities and effect population-level change.

Community-engaged research (CEnR) is a powerful tool to create sustainable and effective change in health outcomes. CEnR engages community members as equal partners, amplifying their voices and priorities by including them throughout the research process. Such engagement increases the relevance and meaning of research, improves the translation of research findings into sustainable health policy and practice, and ultimately enhances mutual trust among academic, clinical, and community partners for ongoing research partnership. There are a number of key principles that must be considered in the planning, design, and implementation of CEnR. These principles are focused on inclusive representation and participation, community empowerment, building community capacity, and protecting community self-determination. Although vascular surgeons may not be equipped to address these issues from the ground up by themselves, they should work with a team who can help them incorporate these elements into their CEnR project designs and proposals. This may be best accomplished by collaborating with researchers and community-based organizations who already have this expertise and have established social capital within the community. This article describes the theory and principles of CEnR, its relevance to vascular surgeons, researchers, and patients, and how using CEnR principles in vascular surgery practice, research, and outreach can benefit our patient population, with a specific focus on reducing disparities related to amputation.

Depression in Patients with Peripheral Artery Disease: An Underdiagnosis with Increased Mortality.

BACKGROUND: Among patients with peripheral artery disease (PAD), depression is diagnosed in 17-25% and negatively impacts wound healing, quality of life, and survival. We hypothesized that depression is underdiagnosed in patients with PAD. Additionally, given the associations between depression and mortality in PAD patients, there is an increased need to investigate the strength of this relationship. The present analysis includes 2 studies to address the following aims: (1) Investigation of the prevalence of concomitant PAD and depression in a cohort from the Southeastern United States, and (2) Examination of the association between depression and all-cause mortality in a cohort of Canadian patients with PAD. METHODS: STUDY 1: From June-August 2022, the Patient Health Questionnaire Module 9 (PHQ-9) was administered to all patients seeking PAD-related care including medical, wound/podiatric, or vascular interventional/surgical treatment, in the University of North Carolina-Chapel Hill Vascular, Wound, and Podiatry clinics. The PHQ-9 assesses symptoms over 2 weeks and is scored 0-27, with higher scores indicating increasingly severe depression. Demographics, primary diagnosis, depression history, and antidepressant prescription were determined through chart review. We compared the proportion of positive depression screenings (PHQ-9 ≥ 5) to known depression. Among those treated for depression, the PHQ-9 score severity was evaluated. T-tests and χ2 tests were used to compare means and proportions. STUDY 2: From July 2015 to October 2016, the Geriatric Depression Scale Short Form was administered to adult patients with PAD undergoing revascularization. The Geriatric Depression Scale Short Form is a self-report measure of depression with a score >5 consistent with depression. The prevalence of depression was determined; primary outcome was all-cause mortality at 6 months. RESULTS: STUDY 1: In 104 PAD patients (mean age 66.6 ± 11.3 years, 37% female), 37% of respondents scored ≥5 on the PHQ-9 survey, indicating at least mild depression. Only 18% of PAD patients had a history of depression, demonstrating a significant difference between the PHQ-9 findings and documented medical history. While depression was underdiagnosed in both men and women, men were more likely to have unrecognized depression (chi-squared statistic = 35.117, df = 1, P < 0.001). Among those with a history of depression, 74% had a current prescription for antidepressant medication, but 57% still had an elevated PHQ-9 score indicating possible undertreatment. STUDY 2: In 148 patients (mean age 70.3 ± 11.0 years, 39% female) the prevalence of screened depression was 28.4%, but only 3.3% had a documented history of depression suggesting significant underdiagnosis. Patients with depression were significantly more likely to die within 6 months of revascularization (9.5% vs. 0.9%; odds ratio 1.48, 95% confidence interval: 1.08 to 2.29). There was no association between depression and risk of length of stay, reintervention, or readmission. CONCLUSIONS: Depression is underdiagnosed and undertreated among patients with PAD, which has grave consequences as it is associated with 1.5 times the odds of mortality within 6 months of revascularization. There is a critical need for more robust screenings and comprehensive mental health treatment for patients with concomitant depression and PAD.

Upstream comprehensive management of individuals with diabetes with multimorbidity and frailty to act against amputation.

This manuscript constitutes a commentary on: "Retrospective cohort study of long-term outcomes and prognostic factors for survival after lower extremity amputation in patients with diabetes" by Vuorlaakso et al. (2023). We aim to contribute to the reflection of their findings to support the comprehensive management of vulnerable individuals with multimorbidity and/frailty for limb preservation. There is an urgent need to understand the effects of frailty on overall survival after amputation, survival without major amputation, and the effect modification with multimorbidity.

Postoperative complications and their association with post-traumatic stress disorder in academic vascular surgeons.

OBJECTIVES: Postoperative complications are an inherent component of surgical practice. This study seeks to address their association with emotional responses of academic vascular surgeons. METHODS: An anonymous electronic survey was sent to all vascular surgery program directors in North America with a request to disseminate to their faculty. The survey captured data on demographics and practice type and used imbedded validated measures to determine emotional responses to postoperative complications and to assess coping mechanisms. Univariate analysis was performed to determine differences between those who reported at least partial symptoms of post-traumatic stress disorder (PTSD) following their worse major complication over the previous year and those who did not. Multivariable logistic regression analysis was performed for all covariates found significant on univariate analysis, and those deemed clinically relevant. RESULTS: The survey was distributed to 267 faculty at 128 institutions in the United States and 10 institutions in Canada and completed by 65 participants (response rate, 32%). Twenty of 65 (31%) identified as female, and the total group had a mean age of 47 ± 10.2 years. Most respondents (43/65; 66%) reported a major complication within 3 months of the survey, with the majority of respondents (45/65; 69%) reporting the outcome of patient mortality. Of respondents, 20 of 65 (31%) demonstrated at least partial symptoms of PTSD in response to the worst complication from the previous year, with 12 of 65 (19%) meeting the clinical diagnosis of PTSD. Respondents in the PTSD group were more likely to criticize/blame themselves following the complication (P = .0028); less likely to identify the complication as "expected" (P = .048) or to believe causes of their complications were due to others/external factors; and more likely to identify as a female (55% vs 20%; P = .008). Regarding support following major complications, most respondents (57/65; 88%) desired the ability to discuss details of the case with a respected peer. The most common external pressure influencing their emotional responses to complications was maintaining reputation and a sense of honor (66%). Gender differences persisted on multivariate analysis (P = .016). CONCLUSIONS: Emotional responses following major postoperative complications in vascular surgery are common and may pose a risk for PTSD. This may occur more commonly following complications that are unexpected or in cases in which the cause of the complication was due to a perceived or actual surgical mistake. The ubiquitous nature and severity of the emotional toll of major complications for vascular surgeons is poorly described and under-recognized. Gender-related differences may exist, and most surgeons desire a support network of respected peers with whom to discuss complications.

Evolution in Trends of Primary Lower-Extremity Amputations Associated With Diabetes or Peripheral Artery Disease From 2006 to 2019.

BACKGROUND: Given the importance in prevention of lower extremity amputations (LEAs) associated with diabetes or peripheral artery disease (PAD), we sought to document the trends of primary LEA in Québec, Canada, from years 2006 to 2019. METHODS: Using the Québec Integrated Chronic Disease Surveillance System, we calculated crude and age-standardized annual incidence rates of primary LEA associated with diabetes and PAD among adults ≥ 40 years (99% confidence intervals [CI]), and all-cause 1-year mortality proportion trends following a primary LEA (95% CI), stratified by minor or major as the highest level of LEA during the same hospital stay and age groups. Trends were assessed using multivariate regression models. RESULTS: In 2019, the crude rate of primary LEA was 116.0 per 100,000 (n = 825) with 93.7 and 21.9 per 100,000 of minor (n = 665) and major (n = 160) LEA, respectively. A tendency of decrease by 8% (-15.0 to 0.4%) of age-standardized incidence of primary LEA was observed between 2006 and 2019, while the absolute number of primary LEA increased from 610 to 825 cases. Minor LEA increased by 14.2% (3.7 to 25.9%) and major LEA decreased by 49.5% (-57.1 to -40.5%). Incidence trends remained stable among the 40 to 64 years, and declined by 14.6% and 20.1% for the 65 to 79 and ≥ 80 years of age groups, respectively. Major LEA decreased in all age groups, whereas minor LEA increased by 26.2% among the patients 40 to 64 years of age only. Age-standardized 1-year mortality decreased by 35.1% (95% CI, -43.4 to -25.7%) between 2006 and 2019, with a crude 1-year mortality of 11.3% in 2019. CONCLUSIONS: The reduction of major LEA and 1-year mortality are encouraging, although increased minor LEA, especially in younger age groups, emphasizes the importance to improve preventive care further.

Females are less likely to receive best medical therapy for stroke prevention before and after carotid revascularization than males.

BACKGROUND: Current professional guidelines recommend best medical therapy (BMT) with statin agents and antiplatelet therapy for primary and secondary stroke prevention in patients with carotid artery stenosis. We aimed to assess the association of patient sex with preoperative BMT in patients undergoing carotid revascularization. METHODS: We performed a retrospective review of Vascular Quality Initiative patients who underwent carotid endarterectomy or carotid artery stenting between January 2003 and February 2022. Multivariable logistic regression models were used to assess the association of patient sex with preoperative BMT after adjusting for sociodemographic, comorbidity, and disease severity characteristics. In-hospital outcomes were assessed by sex and preoperative BMT status. RESULTS: Of 214,008 patients who underwent carotid revascularization, 38.7% (n = 82,855) were female and 61.3% (n = 131,153) were male. Overall, 77.2% (n = 63,922) of females were on preoperative BMT, compared with 80.4% (n = 105,375) of males (P < .001). After adjusting for baseline differences, females had 11% lower odds of being on BMT compared with males (adjusted odds ratio, 0.89; 95% confidence interval, 0.86-0.91). Postoperatively, females had 18% lower odds of being prescribed BMT than males (adjusted odds ratio, 0.82; 95% confidence interval, 0.79-0.84). In-hospital stroke (1.20% vs 1.51%), death (0.37% vs 0.66%), and stroke/death (1.46% vs 1.98%) were all significantly lower for patients on BMT (all P < .001). CONCLUSIONS: There is a significant discrepancy in the proportion of females versus males receiving preoperative BMT for stroke prevention before carotid artery revascularization. In-hospital outcomes are worse in patients without BMT, highlighting the importance of raising awareness and implementing targeted interventions to improve preoperative adherence to stroke prevention guidelines.

Vascular Surgery Research in the Coronavirus Disease 2019 Pandemic: A Sex-Based Bibliometric Analysis.

INTRODUCTION: The COVID-19 pandemic has disrupted vascular surgery services globally and its impact on researchers has illustrated disproportionate barriers for female researchers. We assessed the pandemic's consequences on bibliometric trends in vascular surgery and vascular medicine throughout the pandemic. METHODS: A scoping review was performed using the PubMed/MEDLINE, Scopus, and EMBASE databases from January to December 2020 to identify articles related to COVID-19 and vascular surgery or vascular medicine. Articles only describing cardiac or neurovascular care were excluded. The scoping review was performed according to the PRISMA-ScR guidelines. Bibliometric data were extracted and analyzed. RESULTS: Four hundred and fourteen articles were identified, including 125 (30.2%) original articles, 42 (10.1%) review papers, 105 (25.4%) case reports, 27 (6.5%) editorials and commentaries, 94 (22.7%) letters and correspondences, and 21 (5.1%) conference abstracts. The 5 most common countries of study or discussion were all high-income countries. English was the predominant (n = 393, 94.9%) language. Funding was reported for 5.1% (n = 21) of articles. In the first 6 months, 17.6% (n = 30) of first authors and 10.6% (n = 18) of last authors were female, while the last 6 months saw an increase in representation to 30.6% (n = 74) and 15.6% (n = 38) for first and last author, respectively. CONCLUSION: The pandemic caused a rapid surge in vascular publications related to COVID-19. Female authors remain underrepresented in vascular research and the share in female authorship has dropped early in the pandemic, but rose after the end of the first wave. High-income countries remain overrepresented in research productivity, alluding to important disparities in COVID-19-related literature.

The art of peer review: Guidelines to become a credible and constructive peer reviewer.

Peer review is a learned skill set that requires knowledge of study design, review construct, ethical considerations, and general expertise in a field of study. Participating in peer review is a rewarding and valuable experience in which all academic physicians are encouraged to partake. However, formal training opportunities in peer review are limited. In 2021, the Association of Women Surgeons and the journal Surgery collaborated to develop a Peer Review Academy. This academy is a 1-year longitudinal course that offers a select group of young women surgical trainees across all specialties a curriculum of monthly lectures and multiple formal mentored peer review opportunities to assist them in developing the foundation necessary to transition to independent peer review. The trainees and faculty mentors participating in the Association of Women Surgeons-Surgery Peer Review Academy compiled a summary of best peer review practices, which is intended to outline the elements of the skill set necessary to become a proficient peer reviewer.

A scoping review of malnutrition in patients undergoing interventions for peripheral arterial disease.

BACKGROUND: Peripheral arterial disease (PAD) is associated with comorbid conditions and frailty. The role of preoperative nutrition in patients with PAD has not been well characterized. In the present scoping review, we sought to describe the prevalence and prognostic implications of preoperative malnutrition in patients undergoing vascular interventions for claudication or chronic limb-threatening ischemia (CLTI). METHODS: We systematically searched for studies across six databases from inception to August 2021. Studies that had focused on patients with claudication or CLTI who had undergone open or endovascular procedures were included if preoperative nutrition had been measured and correlated with a clinical outcome. RESULTS: Of 4186 records identified, 24 studies had addressed the prevalence or prognostic effects of malnutrition in patients who had undergone interventions for PAD. The proportion of women included in these studies ranged from 6% to 58%. The prevalence of preoperative malnutrition ranged from 14.6% to 72%. Seven different malnutrition assessments had been used in these studies. Across all the scales, preoperative malnutrition was associated with at least one of the following outcomes: mortality, postoperative complications, length of stay, readmission rates, and delayed wound healing. CONCLUSIONS: A variety of tools were used to measure malnutrition in patients undergoing interventions for PAD. Our findings suggest that preoperative malnutrition is associated with adverse clinical outcomes for patients undergoing open and endovascular procedures for claudication or CLTI and that consensus is lacking regarding which tool to use. Clinicians and surgeons should be sensitized to the importance of assessing for malnutrition preoperatively in adults undergoing interventions for PAD.

Implementation of telemedicine in the care of patients with aortic dissection.

Telemedicine uses telephone-based or any form of digital communication for remote clinical services. It has been a field of interest for the last century, with broader implementation of telemedicine technologies during the last 25 years. The COVID-19 pandemic was an impetus for the adoption of these technologies globally across all health care services, including patient care, surgical practice, and workflow. As part of the patient engagement work in the Aortic Dissection Collaborative, this topic was identified as an important patient-centered research topic. Telemedicine has been adopted increasingly in vascular surgery; however, there is little evidence on appropriate use of these technologies pertaining to treating patients with aortic dissection or aortopathy in general. This landscape review summarizes the uses of telemedicine applications pre and post pandemic in medicine and vascular surgery, with a particular focus on uses in aortopathy. Using common resource databases, we identified articles related to the history of telemedicine, its current utilization, and application to vascular surgery and/or aortopathy. We briefly review the history of telemedicine and illustrate a range of applications in medicine before the pandemic, along with its rapid uptake globally during the COVID-19 pandemic. The enablers and barriers to using telemedicine are explored, although as a whole there is satisfaction with its integration among patients and providers. To address these, we offer recommendations to address future research as it pertains to telemedicine technologies in aortic dissection.
