Gender Differences in Authorship Among Transplant Physicians: Are We Bridging the Gap?

BACKGROUND: Despite an increase in the number of practicing female physicians, gender disparities in academic medicine persist. For investigating gender gap in the transplantation field, this study examined the relationship between gender and authorship among medical and surgical transplant physicians. MATERIALS AND METHODS: In this observational study, all original clinical science articles published in the journals of Transplantation, American Journal of Transplantation, and Clinical Transplantation were reviewed from January 2008 to December 2017. Chi-square analysis was used to compare the proportions of female and male authors, and the Cochrane-Armitage test was used for comparisons over time. RESULTS: A total of 2530 publications and 2988 individual authors met the inclusion criteria for the study. Male physicians published significantly more articles compared to female physicians as first (67.4% versus 30.4%) and senior authors (82.9% versus 16.2%), respectively. There were increases in the proportion of female first and senior authors between 2008 and 2017. The majority of authors with multiple publications were male (73.6%), specifically male medical physicians (44.3%). Male medical physicians were the most productive in publication amount and authorship positions. CONCLUSIONS: While research activity among female physicians increased over time, gender disparity continues to exist among female and male physicians in the transplantation field. Academic activity is lower among females in publication amount and authorship positions. These trends emphasize the need to identify barriers to female physician academic productivity within the transplantation field.

Gender differences in authorship among Hepato-pancreatico-biliary surgeons.

BACKGROUND: While studies have explored the gender gap in scientific publications, no study has investigated surgical literature in much detail. We examined the gender gap in Hepato-pancreato-biliary publications over the last decade. METHODS: All physician authored original clinical science articles published in HPB, Annals of Surgery, Surgery, Annals of Surgical Oncology, and JAMA Surgery were reviewed from 2008 to 2017. Chi square analysis was used to compare the proportions of female and male authors and Cochrane-Armitage test was used for comparisons over time. RESULTS: Of the 1067 publications, 84.0% of all authorships were held by men. Women physicians made up 10.3% of senior and 21.4% of first authorships with increased representation from 2.13% in 2007 to 14.8% in 2017 (p = 0.001). Women physicians comprised 14.1% of senior authors in JAMA Surgery, but only 2.46% in Annals of Surgical Oncology. Male authors were five times more likely to publish multiple articles compared to their female counterparts. Female first authors progressed to senior authors at a rate of 1.13% versus 5.73% for male authors (p = 0.89). CONCLUSION: These findings elucidate the continued underrepresentation of women in senior research roles and the need to recruit and mentor women in all stages of their academic careers.

Evaluating Islet Cell Isolation and Transplantation From Donors Following Medical Assistance in Dying.

Background: Limited information is available regarding outcomes of islet cell isolation (ICI) and transplantation (ITx) using medical assistance in dying (MAiD) donors. We aimed to assess the feasibility and outcomes of ICI and ITx in MAiD donors. Methods: ICI and ITx from MAiD were compared with donation after circulatory death (DCD) type III between 2016 and 2023. Differences of isolated islet equivalents (IEQs), numeric viability and other quantitative in vitro metabolic measures were assessed. Results: Overall, 81 ICIs were available of whom 34 (42%) and 47 (58%) from MAiD and DCD-III, respectively. There were no differences of pancreas and digested tissue weight and islets viability among the 2 groups; however, cold ischemic time was longer in MAiD (11.5 versus 9.1 h; P = 0.021). The IEQ (P < 0.001) and percent trapped (P < 0.001) were higher in the DCD-III; however, MAiD islets demonstrated a higher purity (P = 0.020). Overall, 15 ITx were performed of whom 3 (8.8%) and 12 (25.5%) from MAiD and DCD-III, respectively (P = 0.056). Patients had a median fasting C-peptide of 0.51 ng/mL (interquartile range, 0.30-0.76 nmol/L), with no differences between groups (MAiD = 0.52 versus DCD-III = 0.51; P = 0.718). The median HbA1c was 6.2% (interquartile range, 5.7%-7%) (MAiD = 6.3% versus DCD-III = 6.1%; P = 0.815) and BETA2 scores (MAiD = 7.4 versus DCD-III = 12.8; P = 0.229) did not differ. Conclusions: ICI from MAiD donor pancreas may be successfully transplanted with comparable outcomes to DCD-III and may be used for research. These results justify additional efforts to consider MAiD as another valuable source of grafts for ITx. Further multicenter studies and larger clinical experience are needed to validate our findings.
