RESUMO
OBJECTIVE: To examine sex in human vascular surgery research by quantifying the inclusion and analysis of sex-based data in high-impact vascular surgery journals. METHODS: A bibliographic review of original articles published in the European Journal of Vascular and Endovascular Surgery, Journal of Vascular Surgery, JVS: Venous and Lymphatic Disorders, Journal of Endovascular Therapy, and Annals of Vascular Surgery from January 1, 2018, to December 31, 2020, and from January 1, 2023, to December 31, 2023, was conducted. Abstracted data included sex-based data analysis, inclusion of sex as a variable in multivariable analysis, inclusion of sex as an independent variable, and a discussion of sex-based results. RESULTS: Of the 3762 articles that included human, animal, or cell subjects, 249 (6.6%) did not state sex. Of those 249 articles, 183 included human subjects, 55 included animal subjects, and 11 used cell lines as the subjects. These were removed from analysis as well as the remaining 68 articles with animal subjects. In addition, 23 researched a sex-specific pathology and were removed from analysis. Of the remaining 3422 articles included in our study, 42.3% analyzed sex, 46.9% included sex in multivariable analysis, 4.8% included sex as an independent variable, and 26.6% included a discussion of sex. There were no significant differences in all four sex variables between 2018, 2019, and 2020. Between 2018-2020 and 2023, there were significant increases in all four sex variables. Multicenter studies had significantly higher rates of independent analysis of sex over single-center studies (7.4% vs 3.3%, P < .001). There was no significant difference in independent analysis of sex between U.S.-based and non-U.S.-based studies. Only 191 articles (5.6%) had 90% or greater matching of men and women in their study. CONCLUSIONS: Equitable inclusion and analysis of sex is rare in vascular surgery research. Less than 5% of articles included an independent analysis of data by sex, and few studies included males and females equally. Clinical research is the basis for evidence-based medicine; therefore, it is important to strive for equitable inclusion, analysis, and reporting of data to foster generalizability of clinical research to men and women.
RESUMO
INTRODUCTION: Gastroschisis is the most common congenital abdominal wall defect with a rising prevalence. Infants with gastroschisis are at risk for multiple complications, leading to a potential increased risk for hospital readmission after discharge. We aimed to find the frequency and factors associated with an increased risk of readmission. METHODS: A retrospective analysis of infants born with gastroschisis between 2013 and 2019 who received initial surgical intervention and follow-up care in the Children's Wisconsin health system was performed. The primary outcome was the frequency of hospital readmission within 1 year of discharge. We also compared maternal and infant clinical and demographic variables between those readmitted for reasons related to gastroschisis, and those readmitted for other reasons or not readmitted. RESULTS: Forty of 90 (44%) infants born with gastroschisis were readmitted within 1-year of the initial discharge date, with 33 (37%) of the 90 infants being readmitted due to reasons directly related to gastroschisis. The presence of a feeding tube (p < 0.0001), a central line at discharge (p = 0.007), complex gastroschisis (p = 0.045), conjugated hyperbilirubinemia (p = 0.035), and the number of operations during the initial hospitalization (p = 0.044) were associated with readmission. Maternal race/ethnicity was the only maternal variable associated with readmission, with Black race being less likely to be readmitted (p = 0.003). Those who were readmitted were also more likely to be seen in outpatient clinics and utilize emergency healthcare resources. There was no statistically significant difference in readmission based on socioeconomic factors (all p > 0.084). CONCLUSION: Infants with gastroschisis have a high hospital readmission rate, which is associated with a variety of risk factors including complex gastroschisis, multiple operations, and the presence of a feeding tube or central line at discharge. Improved awareness of these risk factors may help stratify patients in need of increased parental counseling and additional follow-up.
RESUMO
OBJECTIVES: To evaluate the utilization of hematopathology resources within our enterprise on axillary lymph node core biopsy (AxLNCB) specimens, particularly those obtained in the context of breast cancer screening. METHODS: The utilization of hematopathology resources was determined for all AxLNCB specimens over a 30-month period from across our enterprise, and chart review was performed for select patient demographics and radiographic features. The AxLNCB cases with benign histology were reviewed for subtyping of histologic patterns. RESULTS: Of the total 594 AxLNCB specimens, 61.6% were benign and 38.6% malignant. Of malignant cases, only 9.3% contained any hematologic malignancy, yet 94% of all cases received tissue triage for lymphoma, and 81% were reviewed at least in part by a hematopathologist. Six clinical parameters were found to independently predict risk of hematologic malignancy: male sex (P = .041), bilateral lymphadenopathy (P = .004), diffuse cortical thickening (P = .005), lack of breast cancer (P = .001), older age (P < .001), and history of hematologic malignancy (P < .001). CONCLUSIONS: Our enterprise overused hematopathology resources in the evaluation of AxLNCB performed in the study period. Our process could improve from the application of a simple tool generated from this cohort to predict percent risk of the specimen containing hematologic malignancy using patient characteristics easily found via routine chart review.
RESUMO
BACKGROUND: Breast cancer (BC) is the most common cancer among US women, and institutional racism is a critical cause of health disparities. We investigated impacts of historical redlining on BC treatment receipt and survival in the United States. METHODS: Home Owners' Loan Corporation (HOLC) boundaries were used to measure historical redlining. Eligible women in the 2010-2017 Surveillance, Epidemiology, and End Results-Medicare BC cohort were assigned a HOLC grade. The independent variable was a dichotomized HOLC grade: A and B (nonredlined) and C and D (redlined). Outcomes of receipt of various cancer treatments, all-cause mortality (ACM), and BC-specific mortality (BCSM) were analyzed using logistic or Cox models. Indirect effects by comorbidity were examined. RESULTS: Among 18â119 women, 65.7% resided in historically redlined areas (HRAs), and 32.6% were deceased at a median follow-up of 58 months. A larger proportion of deceased women resided in HRAs (34.5% vs 30.0%). Of all deceased women, 41.6% died of BC; a larger proportion resided in HRAs (43.4% vs 37.8%). Historical redlining is a statistically significant predictor of poorer survival after BC diagnosis (hazard ratio = 1.09, 95% confidence interval [CI] = 1.03 to 1.15 for ACM, and hazard ratio = 1.26, 95% CI = 1.13 to 1.41 for BCSM). Indirect effects via comorbidity were identified. Historical redlining was associated with a lower likelihood of receiving surgery (odds ratio = 0.74, 95% CI = 0.66 to 0.83, and a higher likelihood of receiving palliative care odds ratio = 1.41, 95% CI = 1.04 to 1.91). CONCLUSION: Historical redlining is associated with differential treatment receipt and poorer survival for ACM and BCSM. Relevant stakeholders should consider historical contexts when designing and implementing equity-focused interventions to reduce BC disparities. Clinicians should advocate for healthier neighborhoods while providing care.

BACKGROUND: Elevated hydrogen sulfide (H2S) contributes to vasodilatation and hypotension in septic shock, and traditional therapies do not target this pathophysiologic mechanism. High-dose IV hydroxocobalamin scavenges and prevents H2S formation, which may restore vascular tone and may accentuate recovery. No experimental human studies have tested high-dose IV hydroxocobalamin in adults with septic shock. RESEARCH QUESTION: In adults with septic shock, is comparing high-dose IV hydroxocobalamin with placebo feasible? STUDY DESIGN AND METHODS: We conducted a phase 2 single-center, double-blind, allocation-concealed, placebo-controlled, parallel-group pilot randomized controlled trial comparing high-dose IV hydroxocobalamin with placebo in critically ill adults with septic shock. Patients meeting Sepsis 3 criteria were randomized 1:1 to receive a single 5-g dose of high-dose IV hydroxocobalamin or equivalent volume 0.9% saline solution as placebo. The primary outcome was study feasibility (enrollment rate, clinical and laboratory compliance rate, and contamination rate). Secondary outcomes included between-group differences in plasma H2S concentrations and vasopressor dose before and after infusion. RESULTS: Twenty patients were enrolled over 19 months, establishing an enrollment rate of 1.05 patients per month. Protocol adherence rates were 100% with zero contamination. In the high-dose IV hydroxocobalamin group, compared to placebo, there was a greater reduction in vasopressor dose between randomization and postinfusion (-36% vs 4%, P < .001) and randomization and 3-h postinfusion (-28% vs 10%, P = .019). In the high-dose IV hydroxocobalamin group, the plasma H2S level was reduced over 45 mins by -0.80 ± 1.73 µM, as compared with -0.21 ± 0.64 µM in the placebo group (P = .3). INTERPRETATION: This pilot trial established favorable feasibility metrics. Consistent with the proposed mechanism of benefit, high-dose IV hydroxocobalamin compared with placebo was associated with reduced vasopressor dose and H2S levels at all time points and without serious adverse events. These data provide the first proof of concept for feasibility of delivering high-dose IV hydroxocobalamin in septic shock. TRIAL REGISTRY: ClinicalTrials.gov; No.: NCT03783091; URL: www.

BACKGROUND: Residential segregation is an important factor that negatively impacts cancer disparities, yet studies yield mixed results and complicate clear recommendations for policy change and public health intervention. In this study, we examined the relationship between local and Metropolitan Statistical Area (MSA) measures of Black isolation (segregation) and survival among older non-Hispanic (NH) Black women with breast cancer (BC) in the United States. We hypothesized that the influence of local isolation on mortality varies based on MSA isolation-specifically, that high local isolation may be protective in the context of highly segregated MSAs, as ethnic density may offer opportunities for social support and buffer racialized groups from the harmful influences of racism. METHODS: Local and MSA measures of isolation were linked by Census Tract (CT) with a SEER-Medicare cohort of 5,231 NH Black women aged 66-90 years with an initial diagnosis of stage I-IV BC in 2007-2013 with follow-up through 2018. Proportional and cause-specific hazards models and estimated marginal means were used to examine the relationship between local and MSA isolation and all-cause and BC-specific mortality, accounting for covariates (age, comorbidities, tumor stage, and hormone receptor status). FINDINGS: Of 2,599 NH Black women who died, 40.0% died from BC. Women experienced increased risk for all-cause mortality when living in either high local (HR = 1.20; CI = 1.08-1.33; p < 0.001) or high MSA isolation (HR = 1.40; CI = 1.17-1.67; p < 0.001). A similar trend existed for BC-specific mortality. Pairwise comparisons for all-cause mortality models showed that high local isolation was hazardous in less isolated MSAs but was not significant in more isolated MSAs. INTERPRETATION: Both local and MSA isolation are independently associated with poorer overall and BC-specific survival for older NH Black women. However, the impact of local isolation on survival appears to depend on the metropolitan area's level of segregation. Specifically, in highly segregated MSAs, living in an area with high local isolation is not significantly associated with poorer survival. While the reasons for this are not ascertained in this study, it is possible that the protective qualities of ethnic density (e.g., social support and buffering from experiences of racism) may have a greater role in more segregated MSAs, serving as a counterpart to the hazardous qualities of local isolation. More research is needed to fully understand these complex relationships. FUNDING: National Cancer Institute.
