RESUMO
BACKGROUND: Workplace microaggressions are a longstanding but understudied problem in the surgical specialties. Microaggressions in health care are linked to negative emotional and physical health outcomes and can contribute to burnout and suboptimal delivery of patient care. They also negatively impact recruitment, retention, and promotion, which often results in attrition. Further attrition at the time of an impending surgical workforce shortage risks compromising the delivery of health care to the diverse US population, and may jeopardize the financial stability of health care organizations. To date, studies on microaggressions have consisted of small focus groups comprising women faculty or trainees at a single institution. To our knowledge, there are no large, multiorganizational, gender-inclusive studies on microaggressions experienced by practicing surgeons. OBJECTIVE: This study aimed to examine the demographic and occupational characteristics of surgeons who do and do not report experiencing workplace microaggressions and whether these experiences would influence a decision to pursue a career in surgery again. STUDY DESIGN: We developed and internally validated a web-based survey to assess surgeon experiences with microaggressions and the associated sequelae. The survey was distributed through a convenience sample of 9 American College of Surgeons online Communities from November 2022 to January 2023. All American College of Surgeons Communities comprised members who had completed residency or fellowship training and had experience in the surgical workforce. The survey contained demographic, occupational, and validated microaggression items. Analyses include descriptive and chi-square statistics, t tests, and bivariable and multivariable logistic regression. RESULTS: The survey was completed by 377 American College of Surgeons members with the following characteristics: working as a surgeon (80.9%), non-Hispanic White (71.8%), general surgeons (71.0%), aged ≥50 years (67.4%), fellowship-trained (61.0%), and women (58.4%). A total of 254 (67.4%) respondents reported experiencing microaggressions. Younger surgeons (P=.002), women (P<.001), and fellowship-trained surgeons (P=.001) were more likely to report experiencing microaggressions than their counterparts. Surgeons working in academic medical centers or health care systems with teaching responsibilities were more likely to experience microaggressions than those in private practice (P<.01). Surgeons currently working as a surgeon or those who are unable to work reported more experience with microaggressions (P=.003). There was no difference in microaggressions experienced among respondents based on surgical specialty, race/ethnicity, or whether the surgeons reported having a disability. In multivariable logistic regression, women had higher odds of experiencing microaggressions compared with men (adjusted odds ratio, 15.9; 95% confidence interval, 7.7-32.8), and surgeons in private practice had significantly lower odds of experiencing microaggressions compared with surgeons in academic medicine (adjusted odds ratio, 0.3; 95% confidence interval, 0.1-0.8) or in health care systems with teaching responsibilities (adjusted odds ratio, 0.2; 95% confidence interval, 0.1-0.6). Among surgeons responding to an online survey, respondents reporting microaggressions were less likely to say that they would choose a career in surgery again (P<.001). CONCLUSION: Surgeons reporting experience with microaggressions represent a diverse range of surgical specialties and subspecialties. With the continued expansion of surgeon gender and race/ethnicity representation, deliberate efforts to address and eliminate workplace microaggressions could have broad implications for improving recruitment and retention of surgeons.

BACKGROUND: Biliary complications are the most common complications of donation after circulatory death (DCD) liver transplantation and the international experience with DCD transplants suggests increased rates of biliary complications compared to donation after brain death transplants. Therefore, it is important to understand factors that are associated with the development of biliary complications within the Australian DCD context in order to inform future practice. The aim of this study is to determine the incidence of biliary complications after DCD liver transplantation at the Australian National Liver Transplantation Unit and identify factors associated with this outcome. METHODS: A retrospective analysis of all adult DCD liver transplants at the Australian National Liver Transplantation Unit from 2007 to 2015 was undertaken. The primary outcome measure was the incidence of biliary complications and was censored on 31 December 2016. Recipients were then stratified into groups based on the development of biliary complications and risk factor analysis was performed. RESULTS: Biliary complications occurred in 35% of DCD transplants, including seven anastomotic strictures and 10 non-anastomotic strictures. Higher donor risk index scores (P = 0.03), post-transplant portal vein complications (P = 0.042) and peak gamma-glutamyl transferase levels within 7 days post-transplant (P = 0.047) were associated with biliary complications. CONCLUSION: Findings from this study demonstrate that biliary complications remain common in DCD liver recipients. Recipients who developed a biliary complication tended to have higher donor risk index, elevated peak gamma-glutamyl transferase levels within 7 days post-transplant or a portal vein complication. The presence of any of these factors should prompt close monitoring for post-transplant biliary complications.

Autologous saphenous vein grafts are occasionally used in renal transplant recipients, particularly in living donors with short donor vessels or after donor vessel injury during allograft procurement. Autologous saphenous vein graft aneurysm formation is described as a late complication following the use of this conduit in renal transplant. We report a case of a 45-year-old woman who developed an autologous saphenous vein graft aneurysm 21 years after her living donor transplant, which was successfully managed with explantation of the graft, cold perfusion ex situ, and resection of the aneurysm, which was followed by reconstruction using deceased donor iliac vessels. The graft was then successfully reimplanted. Based on this experience and after a review of the literature related to autologous saphenous vein graft aneurysms in renal transplant, we recommend that surveillance for this particular complication should be considered no later than 10 years after implant of an autologous saphenous vein graft when used as an arterial conduit.

With gender parity of medical school graduates having been achieved for well over two decades, it is timely to assess whether this has translated into gender parity for all of the editorial type roles of Australasian medical journals, reflecting a move toward gender equity. Data analysis was undertaken of the gender ratios of the current editorial roles of Australasian medical journals as compared to available Australian Health Workforce data. This reveals some variation in the gender ratios for all of the current range of editorial type positions and, hence, an absence of parity. There are no women holding formal editorial positions at all for 27.7% of these journals, whilst 77.7% of the chief editors' roles are occupied by men. For five out of 18 (27.7%) of the journals, gender parity has been or is close to having been achieved for these particular roles. These gender ratios do not mirror the gender ratios of the wider community of practice for at least 50% of the journals. Hence, it can be seen that gender parity is yet to be achieved for the range of editorial roles of Australasian medical journals, which carries implications for gender equity initiatives.
RESUMO
Surgical site infections (SSI) of the abdominal wall in renal transplant recipients can on occasion require management with negative pressure wound therapy (NPWT). This is often successful, with a low risk of further complications. However, we describe three cases in which persistent or recurrent surgical site sepsis occurred, whilst NPWT was being deployed in adults with either wound dehiscence or initial SSI. This type of complication in the setting of NPWT has not been previously described in renal transplant recipients. Our case series demonstrates that in immunosuppressed transplant recipients, there may be ineffective microbial or bacterial bioburden clearance associated with the NPWT, which can lead to further infections. Hence recognition for infections in renal transplant patients undergoing treatment with NPWT is vital; furthermore, aggressive management of sepsis control with early debridement, antimicrobial use, and reassessment of the use of wound dressing is necessary to reduce the morbidity associated with surgical site infections and NPWT.
RESUMO
BACKGROUND: Abdominal wall surgical site complications following renal transplantation can be challenging to manage. A sub-group of these recipients will require operative management or advanced wound care such as negative pressure wound therapy (NPWT). The aim of this study was to determine if there were any preoperative, intraoperative and postoperative characteristics in our recipients' cohort which were associated with the requirement for such interventions. METHODS: A retrospective review of medical records was performed for all recipients who sustained abdominal wall complications following renal transplantation at our centre from 2006 to 2016. RESULTS: A total of 64/828 recipients (7.7%) had abdominal wall complications. The mean weight for these patients was 84.9 kg (±16.6 kg) and the mean body mass index was 30.2 (±5.1). Forty-five recipients (70%) had a superficial wound dehiscence while nine (14%) had a complete fascial dehiscence. Operative intervention was required in 13/64 patients (20%) and was more likely to be required in the presence of a fascial dehiscence (9/9, 100%) or a wound collection (10/31, 32%) (p < 0.001, p = 0.021). NPWT was used in 17/64 patients (27%) and was more commonly required in patients with diabetes mellitus (10/24, 42%), a complete fascial dehiscence (5/9, 56%) or evidence of infection (16/44, 36%) (p = 0.039, p = 0.034, p = 0.008). CONCLUSIONS: The requirement for either operative management or the use of NPWT in the management of abdominal wall complications following renal transplantation in our experience was more common in recipients with diabetes mellitus, and in the setting of either complete fascial dehiscence, abdominal wall wound collections and/ or infection.

In 2016, the Transplantation Society of Australia and New Zealand, with the support of the Australian Government Organ and Tissue authority, commissioned a literature review on the topic of infectious disease transmission from deceased donors to recipients of solid organ transplants. The purpose of this review was to synthesize evidence on transmission risks, diagnostic test characteristics, and recipient management to inform best-practice clinical guidelines. The final review, presented as a special supplement in Transplantation Direct, collates case reports of transmission events and other peer-reviewed literature, and summarizes current (as of June 2017) international guidelines on donor screening and recipient management. Of particular interest at the time of writing was how to maximize utilization of donors at increased risk for transmission of human immunodeficiency virus, hepatitis C virus, and hepatitis B virus, given the recent developments, including the availability of direct-acting antivirals for hepatitis C virus and improvements in donor screening technologies. The review also covers emerging risks associated with recent epidemics (eg, Zika virus) and the risk of transmission of nonendemic pathogens related to donor travel history or country of origin. Lastly, the implications for recipient consent of expanded utilization of donors at increased risk of blood-borne viral disease transmission are considered.
RESUMO
Acute kidney injury (AKI) after liver transplantation (LT) is a common event, but its pathogenesis remains unclear. The aim of this prospective study is to investigate the potential relationship between postreperfusion gene expression, serum mediators, and the onset of AKI after LT. Sixty-five consecutive patients undergoing LT were included in the study. Reverse transcription polymerase chain reaction (PCR) was performed on liver biopsies. Gene expression of 23 genes involved in ischemia/reperfusion injury (IRI) was evaluated. The serum concentrations of endothelin (ET)-1 and inflammatory cytokines were analyzed. AKI after LT developed in 21 (32%) recipients (AKI group). Reverse transcription PCR of reperfusion biopsy in the AKI group showed higher expression of several genes involved in IRI compared with the non-AKI group. Fold changes in the gene expression of ET-1, interleukin (IL) 18, and tumor necrosis factor α (TNF-α) were associated with creatinine peak value. AKI patients also had significantly higher ET-1, IL18, and TNF-α postoperative serum levels. Multivariate analysis showed that ET-1 (odds ratio [OR], 16.7; 95% confidence interval [CI], 3.34-83.42; P = 0.001) and IL18 (OR, 5.27; 95% CI, 0.99-27.82, P = 0.048) serum levels on postoperative day 1 were independently predictive of AKI. Receiver operating characteristic analysis demonstrated that the combination of biomarkers ET-1+IL18 was highly predictive of AKI (area under the receiver operating characteristic curve, 0.91; 95% CI, 0.83-0.99). Early allograft dysfunction and chronic kidney disease stage ≥ 2 occurred more frequently in AKI patients. These results suggest that the graft itself, rather than intraoperative hemodynamic instability, plays a main role in AKI after LT. These data may have mechanistic and diagnostic implications for AKI after LT. Liver Transplantation 24 922-931 2018 AASLD.

BACKGROUND: Sclerosing peritonitis (SP) is a rare but potentially fatal complication following orthotopic liver transplantation (OLT). The definitive surgical management is via a laparotomy peritonectomy and enterolysis procedure, but this carries risks particularly in the immunosuppressed transplant patient population. The natural history of SP is known from a handful of case reports and series, which mostly report de novo cases arising early on following OLT. The aim of this study was to identify all cases of de novo SP following OLT and the outcomes of management. METHODS: Cases of SP post OLT were identified from the Australian National Liver Transplantation Unit (New South Wales) database of all 1393 adult patients. RESULTS: Three cases of SP were diagnosed between 2 and over 9 years post-transplantation. Two patients proceeded to laparotomy and a peritonectomy and enterolysis procedure of the cocooned bowel. The third was managed conservatively due to a relatively indolent course and their medical co-morbidities. CONCLUSION: SP should be considered in the differential diagnosis in patients post OLT presenting with symptoms of bowel obstruction, even years following transplantation. Surgery may be required in order to achieve a satisfactory outcome in some cases.

Despite the growing data supporting the role of microcirculation in regulating liver function, little of this knowledge has been translated into clinical practice. The aim of this study is to quantify hepatic microcirculation in vivo using sidestream dark field (SDF) imaging and correlate these findings with hepatic blood flow, hemodynamic parameters, and soluble mediators. Postreperfusion hepatic microcirculation was assessed using SDF imaging. Hepatic microcirculation measurements included functional sinusoidal density (cm/cm2 ), sinusoidal diameter (µm), red blood cell velocity (µm/second), volumetric blood flow (pl/second), and flow heterogeneity (FH) index. The serum concentrations of endothelin 1 (ET-1) and other inflammatory markers were analyzed with Luminex technology. Portal venous and hepatic artery flows were measured using a flowmeter. Twenty-eight patients undergoing cadaveric liver transplantations have been included in this study. Early allograft dysfunction (EAD) occurred in 7 (25%) patients and was associated with microcirculatory dysfunction. Low arterial and portal flow, high dose of inotropes, cold ischemia time, steatosis, and high ET-1 levels were all associated with impaired microcirculation. The time interval between portal venous and hepatic arterial reperfusion significantly correlated with the changes of the liver grafts' microcirculation. EAD patients tended to have higher serum levels of ET-1 on postoperative days 1, 2, 5, and 7 (all P < 0.01). Serum levels of ET-1 correlated significantly with microcirculation parameters. In conclusion, postreperfusion hepatic microcirculation is a determinant of organ dysfunction after liver reperfusion and could be used to identify very early patients at risk of EAD.
