Abstract
Fellowship training established by the American Society of Transplant Surgeons and certified by the Transplant Accreditation and Certification Council provides trainees with broad exposure and practice readiness for the core aspects of abdominal transplantation. However, the operative case mix of a new transplant surgeon early in practice is unknown. This study examined the volume and composition of the transplant case mix of early-career transplant surgeons to better inform residents interested in transplantation about potential career opportunities following fellowship. cas 209 early-career transplant surgeons were identified from the UNOS database containing encrypted surgeon-specific identifiers and were included in this study. At 5 years into practice, there were 85 (40.7%) kidney-predominant, 38 (18.2%) liver-predominant, and 86 (41.1%) multiorgan transplant surgeons. Comparing surgeon subgroups, multiorgan surgeons performed more transplants in year 5 of practice than both liver-predominant and kidney-predominant surgeons (both p < .05). This is the first study to describe the transplant case composition of the early-career transplant surgeons. This data can be used to inform aspiring transplant surgeons about potential career opportunities and to assist fellowship programs in guiding and mentoring fellows.

Abstract
PURPOSE OF REVIEW This review explores trends in the United States (US) transplant surgery workforce with a focus on historical demographics, post-fellowship job market, and quality of life reported by transplant surgeons. Ongoing efforts to improve women and racial/ethnic minority representation in transplant surgery are highlighted. Future directions to create a transplant workforce that reflects the diversity of the US population are discussed. RECENT FINDINGS Representation of women and racial and ethnic minorities among transplant surgeons is minimal. Although recent data shows an improvement in the number of Black transplant surgeons from 2% to 5.5% and an increase in women to 12%, the White to Non-White transplant workforce ratio has increased 35% from 2000 to 2013. Transplant surgeons report an average of 4.3 call nights per week and less than five leisure days a month. Transplant ranks 1st among surgical sub-specialties in the prevalence of three well-studied facets of burnout. Concerns about lifestyle may contribute to the decreasing demand for advanced training in abdominal transplantation by US graduates. SUMMARY Minimal improvements have been made in transplant surgery workforce diversity. Sustained and intentional recruitment and promotion efforts are needed to improve the representation of women and minority physicians and advanced practice providers in the field.

Blanco Fernández G, Gómez Bravo MÁ, Briceño Delgado J, Valdivieso López A. A survey of Heads of Surgery and Residents on accessibility and employment in liver transplant teams in Spain. Cir Esp 2019; 97:560-567.

Abstract
INTRODUCTION The access of surgeons to liver transplant teams in Spain is heterogeneous. This study aims to portray the current human resources of Spanish transplant teams, distribution of transplant duties among team members, how transplant team members acquire their skills, their leaders' view of their future, as well the motivations of Spanish General Surgery residents to choose transplantation as their future career choice. METHODS Two different surveys were created, one for head surgeons and one for residents, about the number of team members and their training, recruitment, organization of tasks and motivation to work in transplantation. The questionnaires were e-mailed to both the transplant program directors and the surgical residents. RESULTS There are on average 8 surgeons in each transplant unit. More than four surgeons perform the hepatectomy in 54.2% of the groups, while the graft implantation is performed by more than 4 surgeons at just 25% of the centers. Forty-two percent of the transplant chiefs advocated a fellowship training system, and 87.5% believe that generational turnover is guaranteed. Out of 525 residents, 101 responded. Regarding training, 12.8% had no interest in transplantation. Concerning their work preferences, 37.6% were not interested in transplantation because it is excessively demanding, and 52.5% would not like to be part of a liver transplant team in the future. CONCLUSIONS The generational turnover seems to be guaranteed according to liver transplant program directors. The new generations of surgeons generally opt for other areas of surgery other than transplantation. Studies with a greater number of responses are necessary to validate these results.

Organ procurement center allows for daytime liver transplantation with less resource utilization: May address burnout, pipeline, and safety for field of transplantation. Am J Transplant 2019; 19:1296-1304.

Abstract
Abdominal organ transplantation faces several challenges: burnout, limited pipeline of future surgeons, changes in liver allocation potentially impacting organ procurement travel, and travel safety. The organ procurement center (OPC) model may be one way to mitigate these issues. Liver transplants from 2009 to 2016 were reviewed. There were 755 liver transplants performed with 525 OPC and 230 in-hospital procurements. The majority of transplants (87.4%) were started during daytime hours (5 am-7 pm). Transplants with any portion occurring after-hours were more likely to have procurements in-hospital (P < .001). Daytime cases (n = 400) had more OPC procured livers and hepatitis C recipients and were less likely to have a donation after circulatory death donor (all P < .05). In adjusted analyses, daytime cases were independently associated with extubation in the operating room and less postoperative transfusion. There were no significant differences in short- or long-term postoperative outcomes. For exported livers, 54.3% were procured by a local team, saving 137 flights (151 559 miles). The OPC resulted in optimally timed liver transplants and decreased resource utilization with no negative impact on patient outcomes. It allows for ease in exporting organs procured by local surgeons, and potentially addresses provider burnout, the transplant surgery pipeline, and surgeon travel.

Abstract
Decellularization, a technique used in liver regenerative medicine, is the removal of all the cellular components from a tissue or organ, leaving behind an intact structure of extracellular matrix. The biomechanical properties of this novel scaffold material are currently unknown and are important due to the mechanosensitivity of liver cells. Characterizing this material is important for bioengineering liver tissue from this decellularized scaffold as well as creating new 3-dimensional mimetic structures of liver extracellular matrix. This study set out to characterize the biomechanical properties of perfused liver tissue in its native and decellularized states on both a macro- and nano-scale. Poroviscoelastic finite element models were then used to extract the fluid and solid mechanical properties from the experimental data. Tissue-level spherical indentation-relaxation tests were performed on 5 native livers and 8 decellularized livers at two indentation rates and at multiple perfusion rates. Cellular-level spherical nanoindentation was performed on 2 native livers and 1 decellularized liver. Tissue-level results found native liver tissue to possess a long-term Young's modulus of 10.5 kPa and decellularized tissue a modulus of 1.18 kPa. Cellular-level testing found native tissue to have a long-term Young's modulus of 4.40 kPa and decellularized tissue to have a modulus of 0.91 kPa. These results are important for regenerative medicine and tissue engineering where cellular response is dependent on the mechanical properties of the engineered scaffold.

Abstract
The incidence of Clostridium difficile infection (CDI) is increasing among hospitalized patients. Liver transplantation (LT) patients are at higher risk for acquiring CDI. Small, single-center studies (but no nationwide analyses) have assessed this association. We used the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project (2004-2008) for this retrospective, cross-sectional study. Patients with any discharge diagnosis of LT composed the study population, and they were identified with International Classification of Diseases, Ninth Revision, Clinical Modification codes. Those with a discharge diagnosis of CDI were considered cases. Our primary outcomes were the prevalence of CDI and the effects of CDI on inpatient mortality. Our secondary outcomes included the length of stay and hospitalization charges. A regression analysis was used to derive odds ratios (ORs) adjusted for potential confounders. There were 193,174 discharges with a diagnosis of LT from 2004 to 2008. The prevalence of CDI was 2.7% in the LT population and 0.9% in the non-LT population (P < 0.001). Most of the LT patients were 50 to 64 years old. LT patients had higher odds of developing CDI [OR = 2.88, 95% confidence interval (CI) = 2.68-3.10]. Increasing age and increasing comorbidity (including inflammatory bowel disease and nasogastric tube placement) were also independent CDI risk factors. CDI was associated with a higher mortality rate: 5.5% for LT patients with CDI versus 3.2% for LT-only patients (adjusted OR = 1.70, 95% CI = 1.29-2.25). In conclusion, the prevalence of CDI is higher for LT patients versus non-LT patients (2.7% versus 0.9%). CDI is an independent risk factor for mortality in the LT population.

Abstract
The American Society of Transplant Surgeons (ASTS) sought whether the right number of abdominal organ transplant surgeons are being trained in the United States. Data regarding fellowship training and the ensuing job market were obtained by surveying program directors and fellowship graduates from 2003 to 2005. Sixty-four ASTS-approved programs were surveyed, representing 139 fellowship positions in kidney, pancreas and/or liver transplantation. One-quarter of programs did not fill their positions. Forty-five fellows graduated annually. Most were male (86%), aged 31-35 years (57%), married (75%) and parents (62%). Upon graduation, 12% did not find transplant jobs (including 8% of Americans/Canadians), 14% did not get jobs for transplanting their preferred organ(s), 11% wished they focused more on transplantation and 27% changed jobs early. Half fellows were international medical graduates; 45% found US/Canadian transplant jobs, particularly 73% with US/Canadian residency training. Fellows reported adequate exposure to training volume, candidate selection, pre/postoperative care and organ procurement, but not to donor management/selection, outpatient care and core didactics. One-sixth noted insufficient 'mentoring/preparation for a transplantation career'. Currently, there seem to be enough trainees to fill entry-level positions. One-third program directors believe that there are too many trainees, given the current and foreseeable job market. ASTS is assessing the total workforce of transplant surgeons and evolving manpower needs.
