Disparities Persist Among Hispanic Patients: Completing Evaluation, Waitlisting, and Receiving a Kidney Transplant.

Background: Hispanic patients receive disproportionately fewer kidney transplants (KT) than non-Hispanic White (NHW) patients. In this observational study, we evaluated disparities in completing evaluation steps to KT among Hispanic patients. Methods: Using medical records of Hispanic and NHW patients initiating evaluation at 4 transplant centers from January 2011 to March 2020, we performed sequential Cox models to compare Hispanic versus NHW patients reaching each step of the evaluation process until receiving a KT. Results: Among all 5197 patients (Hispanic n = 2473; NHW n = 2724) initiating evaluation, Hispanic patients had 8% lower risk to be approved by the kidney pancreas (KP) committee than NHW patients (adjusted hazard ratio [aHR], 0.92; 95% confidence intervals (CI), 0.86-0.98; P = 0.015). Among 3492 patients approved by the KP committee, Hispanic patients had 13% lower risk to be waitlisted than NHW patients (aHR, 0.87; 95% CI, 0.81-0.94; P = 0.004). Among 3382 patients who were waitlisted, Hispanic patients had 11% lower risk than NHW patients to receive KT (aHR, 0.89; 95% CI, 0.81-0.97; P = 0.011). Among all patients initiating evaluation, Hispanic patients had a 16% lower risk than NHW patients to reach KT (aHR, 0.84; 95% CI, 0.76-0.92; P = 0.0002). Conclusions: Our study found that disproportionately fewer Hispanic patients were approved by the KP committee, were waitlisted, and received a KT, particularly a living donor kidney transplant, than NHW patients. Closer oversight of the evaluation process may help patients overcome challenges in access to KT.

Adverse Events of Surgical Drain Placement: An Analysis of the NSQIP Database.

BACKGROUND: Surgical site drainage is important to prevent hematoma, seroma, and abscess formation. However, the placement of drain placement also predispose patients to several postoperative complications. The aim of this study is to clarify the risk-benefit profile of surgical drain placement. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Procedure-Targeted Databases were used to identify patients who underwent hepatectomy, pancreatectomy, nephrectomy, cystectomy, and prostatectomy. Patients who underwent each procedure were divided into 2 groups based on intraoperative drain placement. Propensity score-matched cohorts of these 2 groups were compared in terms of postoperative adverse events, readmission, reoperation, and length of stay. RESULTS: Hepatectomy patients with drains experienced organ space infections (P < .001), sepsis (P < .001), and readmission (P = .021) more often than patients without drains. Patients who underwent pancreatectomy and had drains placed experienced wound dehiscence less frequently than those without drains (P = .04). For hepatectomy, pancreatectomy, nephrectomy, and prostatectomy populations, patients with drains had longer lengths of stay (P < .05). Matched populations across all procedures did not differ in terms of reoperation rate. DISCUSSION: Prophylactic surgical drain placement may be associated with increased infectious complications and prolonged length of stay. Further studies are needed to elucidate the complete adverse event profile of surgical drains. Nonetheless, outcomes may be improved with better patient selection or advancements in drain technology.

Analysis of Diversity, Equity, and Inclusion Initiatives Presented Across US Academic Department of Surgery Websites in 2021.

Despite increased attention devoted to diversity, equity, and inclusion (DEI) within academic medicine, representation, lack of workforce and leadership diversity, and bias within medicine remain persistent problems. The purpose of the current study was to understand the current efforts and attention to DEI within academic departments of surgery in the United States. 251 department of surgery websites were reviewed, using a standardized data collection form and scoring procedure, accompanied by a 10 percent fidelity check by an independent reviewer. Only 16% of departments of surgery included DEI-specific information, such as a DEI mission statement or initiatives on their departmental sites, with less than seven percent of departments reporting a DEI committee. Such public information may have implications for recruitment and retention of diverse faculty and trainees, downstream effects for patient care, and could be critical to public accountability to improve diversity and create a culture of equity and inclusion.

Financial Impact of a Culturally Sensitive Hispanic Kidney Transplant Program on Increasing Living Donation.

BACKGROUND: In the United States, Hispanic/Latinx patients receive disproportionately fewer living donor kidney transplants (LDKTs) than non-Hispanic White patients. Northwestern Medicine's culturally targeted Hispanic Kidney Transplant Program (HKTP) was found to increase LDKTs in Hispanic patients at 1 of 2 transplant programs with greater implementation fidelity. METHODS: We conducted a budget impact analysis to evaluate HKTP's impact on program financial profiles from changes in volume of LDKTs and deceased donor kidney transplants (DDKTs) in 2017 to 2019. We estimated HKTP programmatic costs, and kidney transplant (KT) program costs and revenues. We forecasted transplant volumes, HKTP programmatic costs, and KT program costs and revenues for 2022-2024. RESULTS: At both programs, HKTP programmatic costs had <1% impact on total KT program costs, and HKTP programmatic costs comprised <1% of total KT program revenues in 2017-2019. In particular, the total volume of Hispanic KTs and HKTP LDKTs increased at both sites. Annual KT program revenues of HKTP LDKTs and DDKTs increased by 226.9% at site A and by 1042.9% at site B when comparing 2019-2017. Forecasted HKTP LDKT volume showed an increase of 36.4% (site A) and 33.3% (site B) with a subsequent increase in KT program revenues of 42.3% (site A) and 44.3% (site B) among HKTP LDKTs and DDKTs. CONCLUSIONS: HKTP programmatic costs and KT evaluation costs are potentially recoverable by reimbursement of organ acquisition costs and offset by increases in total KT program revenues of LDKTs; transplant programs may find implementation of the HKTP financially manageable.

The use of synthetic agonists of quorum sensing N- acyl homoserine lactone pathway improves the bioleaching ability in Acidithiobacillus and Pseudomonas bacteria.

Metal solubilization from discarded electrical material and electronic devices (e-waste) using the bioleaching capabilities of bacterial cells is highly effective. However, gaps in understanding about the microbiological processes involved in the bioleaching reaction leads to less efficient metal solubilization in large-scale e-waste processing. In this study, bacterial species belonging to the genera Acidithiobacillus and Pseudomonas were used to leach copper and gold from discarded printed circuit boards (PCB). Through modulation of the cell-to-cell communication system in these bacteria, phenotypic traits directly involved in the bioleaching reaction were regulated in order to improve the metal solubilization. Addition of the long chain synthetic autoinducer molecule N-acyl homoserine lactone (AHL) of the quorum sensing pathway to the bioleaching reaction resulted in a significant enhancement of metal extraction from PCB. Factors such as: cell attachment to PCB, biofilm formation and hydrogen cyanide (HCN) production were regulated by the quorum sensing system and could be directly related to the improvement of metal bioleaching. Bioleaching reactions using bacterial quorum sensing modulation could represent a valuable tool in overcoming limitations at the industrial level imposed by microbiological traits that lead to inefficient metal bioleaching from e-waste.

Impact of Portal Hypertension on Adverse Events after Splenic Arterial Aneurysm Embolization.

PURPOSE: To evaluate the outcomes of splenic artery aneurysm (SAA) embolization and compare adverse event (AE) rates after embolization in patients with and without portal hypertension (PHTN). MATERIALS AND METHODS: A retrospective review of all patients who underwent embolization of SAAs at 2 institutions was performed (34 patients from institution 1 and 7 patients from institution 2). Baseline demographic characteristics, preprocedural imaging, procedural techniques, and postprocedural outcomes were evaluated. Thirty-day postprocedural severe and life-threatening AEs were evaluated using the Society of Interventional Radiology guidelines. Thirty-day mortality and readmission rates were also evaluated. t test, χ2 test, and/or Fisher exact test were used for the statistical analysis. RESULTS: There was no statistically significant difference between patients with and without PHTN in the location, number, and size of SAA(s). All procedures were technically successful. There were 13 (32%) patients with and 28 (68%) patients without PHTN. The 30-day mortality rate (31% vs 0%; P = .007), readmission rates (61% vs 7%; P < .001), and severe/life-threatening AE rates (69% vs 0%; P < .001) were significantly higher in patients with PHTN than in those without PHTN. CONCLUSIONS: There was a significantly higher mortality and severe/life-threatening AE rate in patients with PHTN than in those without PHTN. SAAs in patients with PHTN need to be managed very cautiously, given the risk of severe/life-threatening AEs after embolization.

Implementation and modification of an organizational-level intervention: a prospective analysis.

BACKGROUND: Modifications to interventions can jeopardize intervention outcomes. Pre-existing perceived barriers and facilitators to the intervention arising in the implementation preparation phase may help explain why modifications to the intervention may occur during the implementation phase. This two-site comparative case study describes modifications made to a complex organizational-level intervention and examines how known implementation science factors may have enabled such changes to occur. METHODS: Northwestern Medicine'sTM Hispanic Kidney Transplant Program (HKTP) is a culturally competent transplant center-based intervention designed to reduce disparities in living donor kidney transplantation among Hispanics. In-depth qualitative interviews and discussions were longitudinally conducted with transplant stakeholders (i.e., physicians, administrators, clinicians) at two kidney transplant programs with large Hispanic populations during implementation preparation and implementation phases. The Consolidated Framework for Implementation Research (CFIR) guided interview design and qualitative analysis, and Stirman's Framework for Reporting Adaptations and Modifications-Expanded (FRAME) guided modification classification. RESULTS: Across sites, 57 stakeholders participated in an interview, group discussion, and/or learning collaborative discussion. Site-B made more modifications than Site-A (n = 29 versus n = 18). Sites differed in the proportions of delaying/skipping (Site-A 50% versus Site-B 28%) and adding (Site-A 11% versus Site-B 28%) but had comparable substituting (Site-A 17% versus Site-B 17%) and tweaking (Site-A 17% versus Site-B 14%) modification types. Across sites, the transplant team consistently initiated the most modifications (Site-A 66%; Site-B 62%). While individuals initiated slightly more modifications at Site-B (21% versus Site-A 17%), institutions instigated proportionately slightly more modifications at Site-A (17% versus Site-B 10%). CFIR inner setting factors (i.e., structural characteristics, culture, available resources, implementation climate) that prominently emerged during the implementation preparation phase explained similarities and differences in sites' modification numbers, types, and agents in the implementation phase. CONCLUSION: Organizations implementing a culturally competent care intervention made modifications. CFIR inner setting factors emerging in the implementation preparation phase largely explained similarities and differences in study sites' modifications. Identifying factors contributing to modifications may help institutions become better prepared to implement an intervention by addressing known factors in advance, which may foster greater fidelity leading to desired outcomes. TRIAL REGISTRATION: ClinicalTrials.gov NCT03276390 . We registered the study retrospectively on 9-7-17.

Sustainment of a complex culturally competent care intervention for Hispanic living donor kidney transplantation: A longitudinal analysis of adaptations.

Introduction: Sustainment refers to continued intervention delivery over time, while continuing to produce intended outcomes, often with ongoing adaptations, which are purposeful changes to the design or delivery of an intervention to improve its fit or effectiveness. The Hispanic Kidney Transplant Program (HKTP), a complex, culturally competent intervention, was implemented in two transplant programs to reduce disparities in Hispanic/Latinx living donor kidney transplant rates. This study longitudinally examined the influence of adaptations on HKTP sustainment. Methods: Qualitative interviews, learning collaborative calls, and telephone meetings with physicians, administrators, and staff (n = 55) were conducted over three years of implementation to identify HKTP adaptations. The Framework for Reporting Adaptations and Modifications-Expanded was used to classify adaptation types and frequency, which were compared across sites over time. Results: Across sites, more adaptations were made in the first year (n = 47), then fell and plateaued in the two remaining years (n = 35). Adaptations at Site-A were consistent across years (2017: n = 18, 2018: n = 17, 2019: n = 14), while Site-B made considerably fewer adaptations after the first year (2017: n = 29, 2018: n = 18, 2019: n = 21). Both sites proportionally made mostly skipping (32%), adding (20%), tweaking (20%), and substituting (16%) adaptation types. Skipping- and substituting-type adaptations were made due to institutional structural characteristics and lack of available resources, respectively. However, Site-A's greater proportion of skipping-type adaptations was attributed to greater system complexity, and Site-B's greater proportion of adding-type adaptation was attributed to the egalitarian team-based culture. Conclusion: Our findings can help prepare implementers to expect certain context-specific adaptations and preemptively avoid those that hinder sustainment.

Impact of having potential living donors on ethnic/racial disparities in access to kidney transplantation.

Racial/ethnic disparities persist in patients' access to living donor kidney transplantation (LDKT). This study assessed the impact of having available potential living donors (PLDs) on candidates' receipt of a kidney transplant (KT) and LDKT at two KT programs. Using data from our clinical trial of waitlisted candidates (January 1, 2014-December 31, 2019), we evaluated Hispanic and Non-Hispanic White (NHW) KT candidates' number of PLDs. Multivariable logistic regression assessed the impact of PLDs on transplantation (KT vs. no KT; for KT recipients, LDKT vs. deceased donor KT). A total of 847 candidates were included, identifying as Hispanic (45.8%) or NHW (54.2%). For Site A, both Hispanic (adjusted OR = 2.26 [95% CI 1.13-4.53]) and NHW (OR = 2.42 [1.10-5.33]) candidates with PLDs completing the questionnaire were more likely to receive a KT. For Site B, candidates with PLDs were not significantly more likely to receive KT. Among KT recipients at both sites, Hispanic (Site A: OR = 21.22 [2.44-184.88]; Site B: OR = 25.54 [7.52-101.54]), and NHW (Site A: OR = 37.70 [6.59-215.67]; Site B: OR = 15.18 [5.64-40.85]) recipients with PLD(s) were significantly more likely to receive a LDKT. Our findings suggest that PLDs increased candidates' likelihood of KT receipt, particularly LDKT. Transplant programs should help candidates identify PLDs early in transplant evaluation.

Preoperative portal vein recanalization-transjugular intrahepatic portosystemic shunt for chronic obliterative portal vein thrombosis: Outcomes following liver transplantation.

High-grade portal vein thrombosis (PVT) is often considered to be a technically challenging scenario for liver transplantation (LT) and in some centers a relative contraindication. This study compares patients with chronic obliterative PVT who underwent portal vein recanalization-transjugular intrahepatic portosystemic shunt (PVR-TIPS) and subsequent LT to those with partial nonocclusive PVT who underwent LT without an intervention. This institutional review board-approved study analyzed 49 patients with cirrhosis with PVT from 2000 to 2020 at our institution. Patients were divided into two groups, those that received PVR-TIPS due to anticipated surgical challenges from chronic obliterative PVT and those who did not because of partial PVT. Demographic data and long-term outcomes were compared. A total of 35 patients received PVR-TIPS while 14 did not, with all receiving LT. Patients with PVR-TIPS had a higher Yerdel score and frequency of cavernoma than those that did not. PVR-TIPS was effective in decreasing portosystemic gradient (16 down to 8 mm HG; p < 0.05). Both groups allowed for end-to-end anastomoses in >90% of cases. However, veno-veno bypass was used significantly more in patients who did not receive PVR-TIPS. Additionally, patients without PVR-TIPS required significantly more intraoperative red blood cells. Overall survival was not different between groups. PVR-TIPS demonstrated efficacy in resolving PVT and allowed for end-to-end portal vein anastomoses. PVR-TIPS is a viable treatment option for chronic obliterative PVT with or without cavernoma that simplifies the surgical aspects of LT.

A multicentre outcome analysis to define global benchmarks for donation after circulatory death liver transplantation.

BACKGROUND & AIMS: The concept of benchmarking is established in the field of transplant surgery; however, benchmark values for donation after circulatory death (DCD) liver transplantation are not available. Thus, we aimed to identify the best possible outcomes in DCD liver transplantation and to propose outcome reference values. METHODS: Based on 2,219 controlled DCD liver transplantations, collected from 17 centres in North America and Europe, we identified 1,012 low-risk, primary, adult liver transplantations with a laboratory MELD score of ≤20 points, receiving a DCD liver with a total donor warm ischemia time of ≤30 minutes and asystolic donor warm ischemia time of ≤15 minutes. Clinically relevant outcomes were selected and complications were reported according to the Clavien-Dindo-Grading and the comprehensive complication index (CCI). Corresponding benchmark cut-offs were based on median values of each centre, where the 75th-percentile was considered. RESULTS: Benchmark cases represented between 19.7% and 75% of DCD transplantations in participating centres. The 1-year retransplant and mortality rates were 4.5% and 8.4% in the benchmark group, respectively. Within the first year of follow-up, 51.1% of recipients developed at least 1 major complication (≥Clavien-Dindo-Grade III). Benchmark cut-offs were ≤3 days and ≤16 days for ICU and hospital stay, ≤66% for severe recipient complications (≥Grade III), ≤16.8% for ischemic cholangiopathy, and ≤38.9 CCI points 1 year after transplant. Comparisons with higher risk groups showed more complications and impaired graft survival outside the benchmark cut-offs. Organ perfusion techniques reduced the complications to values below benchmark cut-offs, despite higher graft risk. CONCLUSIONS: Despite excellent 1-year survival, morbidity in benchmark cases remains high. Benchmark cut-offs targeting morbidity parameters offer a valid tool to assess the protective value of new preservation technologies in higher risk groups and to provide a valid comparator cohort for future clinical trials. LAY SUMMARY: The best possible outcomes after liver transplantation of grafts donated after circulatory death (DCD) were defined using the concept of benchmarking. These were based on 2,219 liver transplantations following controlled DCD donation in 17 centres worldwide. Donor and recipient combinations with higher risk had significantly worse outcomes. However, the use of novel organ perfusion technology helped high-risk patients achieve similar outcomes as the benchmark cohort.

Effectiveness of a culturally competent care intervention in reducing disparities in Hispanic live donor kidney transplantation: A hybrid trial.

Hispanic patients receive disproportionately fewer living donor kidney transplants (LDKTs) than non-Hispanic Whites (NHWs). The Northwestern Medicine Hispanic Kidney Transplant Program (HKTP), designed to increase Hispanic LDKTs, was evaluated as a nonrandomized, implementation-effectiveness hybrid trial of patients initiating transplant evaluation at two intervention and two similar control sites. Using a mixed method, observational design, we evaluated the fidelity of the HKTP implementation at the two intervention sites. We tested the impact of the HKTP intervention by evaluating the likelihood of receiving LDKT comparing pre-intervention (January 2011-December 2016) and postintervention (January 2017-March 2020), across ethnicity and centers. The HKTP study included 2063 recipients. Intervention Site A exhibited greater implementation fidelity than intervention Site B. For Hispanic recipients at Site A, the likelihood of receiving LDKTs was significantly higher at postintervention compared with pre-intervention (odds ratio [OR] = 3.17 95% confidence interval [1.04, 9.63]), but not at the paired control Site C (OR = 1.02 [0.61, 1.71]). For Hispanic recipients at Site B, the likelihood of receiving an LDKT did not differ between pre- and postintervention (OR = 0.88 [0.40, 1.94]). The LDKT rate was significantly lower for Hispanics at paired control Site D (OR = 0.45 [0.28, 0.90]). The intervention significantly improved LDKT rates for Hispanic patients at the intervention site that implemented the intervention with greater fidelity. Registration: ClinicalTrials.gov registered (retrospectively) on September 7, 2017 (NCT03276390).

Contemporary Algorithm for the Management of Hepatocellular Carcinoma in 2021: The Northwestern Approach.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a major cause of cancer-related morbidity and mortality around the world. Frequently, concurrent liver dysfunction and variations in tumor burden make it difficult to design effective and standardized treatment pathways. Contemporary treatment guidelines designed for an era of personalized medicine should consider these features in a more clinically meaningful way to improve outcomes for patients across the HCC spectrum. Given the heterogeneity of HCC, we propose a detailed clinical algorithm for selecting optimal treatment using an evidence-based and practical approach, incorporating liver function, tumor burden, the extent of disease, and ultimate treatment intent, with the goal of individualizing clinical decision making.

Explicit and implicit markers of fairness preeminence in criminal judges.

Achieving justice could be considered a complex social decision-making scenario. Despite the relevance of social decisions for legal contexts, these processes have still not been explored for individuals who work as criminal judges dispensing justice. To bridge the gap, we used a complex social decision-making task (Ultimatum game) and tracked a heart rate variability measurement: the square root of the mean squared differences of successive NN intervals (RMSSD) at their baseline (as an implicit measurement that tracks emotion regulation behavior) for criminal judges (n = 24) and a control group (n = 27). Our results revealed that, compared to controls, judges were slower and rejected a bigger proportion of unfair offers. Moreover, the rate of rejections and the reaction times were predicted by higher RMSSD scores for the judges. This study provides evidence about the impact of legal background and expertise in complex social decision-making. Our results contribute to understanding how expertise can shape criminal judges' social behaviors and pave the way for promising new research into the cognitive and physiological factors associated with social decision-making.

Financial Feasibility Analysis of a Culturally and Linguistically Competent Hispanic Kidney Transplant Program.

BACKGROUND: In 2006, Northwestern Medicine implemented a culturally targeted and linguistically congruent Hispanic Kidney Transplant Program (HKTP). The HKTP has been associated with a reduction in Hispanic/Latino disparities in live donor kidney transplantation. This article assessed the financial feasibility of implementing the HKTP intervention at 2 other transplant centers. METHODS: We examined the impact of the HKTP on staffing costs compared with the total transplant center costs using data from monthly time studies conducted among transplant staff involved in the HKTP. Time studies were conducted during the HKTP preimplementation (2016) and implementation (2017) phases. Labor costs were estimated using data from the time studies and mean salaries from the Department of Labor. We retrospectively examined kidney acquisition and transplant costs at both centers in 2016 and 2017 using data from the Medicare cost reports. RESULTS: During preimplementation, center A staff (n = 21) committed 764 hours ($44 607), and center B staff (n = 15) committed 800 hours ($45 193) to establish the HKTP. During implementation, center A staff (n = 19) committed 1125 hours ($55 594), and center B staff (n = 24) committed 1396 hours ($64 170), in delivering the HKTP. Overall, the total costs from the staffing time involved in the HKTP encompassed <1.0% per year (2016 and 2017) of each center's annual total costs. CONCLUSIONS: Our findings suggest the financial feasibility of implementing the HKTP and present a potential business case for the HKTP's implementation at other transplant centers to reduce health disparities in live donor kidney transplantation.

Liver Transplantation Following Yttrium-90 Radioembolization: 15-Year Experience in 207-Patient Cohort.

BACKGROUND AND AIMS: Radioembolization (yttrium-90 [Y90]) is used in hepatocellular carcinoma (HCC) as a bridging as well as downstaging liver-directed therapy to curative liver transplantation (LT). In this study, we report long-term outcomes of LT for patients with HCC who were bridged/downstaged by Y90. APPROACH AND RESULTS: Patients undergoing LT following Y90 between 2004 and 2018 were included, with staging by United Network for Organ Sharing (UNOS) tumor-node-metastasis criteria at baseline pre-Y90 and pre-LT. Post-Y90 toxicities were recorded. Histopathological data of HCC at explant were recorded. Long-term outcomes, including overall survival (OS), recurrence-free survival (RFS), disease-specific mortality (DSM), and time-to-recurrence, were reported. Time-to-endpoint analyses were estimated using Kaplan-Meier. Univariate and multivariate analyses were performed using a log-rank test and Cox proportional-hazards model, respectively. During the 15-year period, 207 patients underwent LT after Y90. OS from LT was 12.5 years, with a median time to LT of 7.5 months [interquartile range, 4.4-10.3]. A total of 169 patients were bridged, whereas 38 were downstaged to LT. Respectively, 94 (45%), 60 (29%), and 53 (26%) patients showed complete, extensive, and partial tumor necrosis on histopathology. Three-year, 5-year, and 10-year OS rates were 84%, 77%, and 60%, respectively. Twenty-four patients developed recurrence, with a median RFS of 120 (95% confidence interval, 69-150) months. DSM at 3, 5, and 10 years was 6%, 11%, and 16%, respectively. There were no differences in OS/RFS for patients who were bridged or downstaged. RFS was higher in patients with complete/extensive versus partial tumor necrosis (P < 0.0001). For patients with UNOS T2 treated during the study period, 5.2% dropped out because of disease progression. CONCLUSIONS: Y90 is an effective treatment for HCC in the setting of bridging/downstaging to LT. Patients who achieved extensive or complete necrosis had better RFS, supporting the practice of neoadjuvant treatment before LT.

Analysis of Linguistically and Culturally Tailored Initiatives in Websites of Kidney Transplant Programs in the United States Between 2013-2018.

INTRODUCTION: Minority patients constitute the majority of the kidney transplant waiting list, yet they suffer greater difficulties in listing and longer wait times to transplantation. There is a lack of information regarding targeted efforts by transplant centers to improve transplant care for minority populations. RESEARCH QUESTION: Our aim was to analyze all kidney transplant websites in the United States to identify changes over a 5-year period in the number of multilingual websites, reported culturally targeted initiatives, and center and provider diversity. DESIGN: Surveys were developed to analyze center websites of all transplant programs in the United States. Those with incomplete information about their nephrology or surgical teams were excluded, resulting in 174 (73%) sites in 2013 and 185 (76%) in 2018. Results: Few websites were available in a language other than English, 6.3% in 2013 and 9.7% in 2018 (P = 0.24). Only 3 websites (1.3%) in 2013 and 7 (3.7%) in 2018 reported any evidence of a culturally targeted initiative (P = 0.23). In 2018, 35% of centers employed a Hispanic transplant physician, 77% had a transplant physician who spoke a language other than English, and 39% had a transplant physician who spoke Spanish. DISCUSSION: Although minority patients are expected to grow in the United States, decreased access to transplantation continues to vex the transplant community. Very little progress has been made in the development of multilingual websites and culturally targeted initiatives.

Implementing culturally competent transplant care and implications for reducing health disparities: A prospective qualitative study.

BACKGROUND: Despite available evidence-based interventions that decrease health disparities, these interventions are often not implemented. Northwestern Medicine's® Hispanic Kidney Transplant Program (HKTP) is a culturally and linguistically competent intervention designed to reduce disparities in living donor kidney transplantation (LDKT) among Hispanics/Latinos. The HKTP was introduced in two transplant programs in 2016 to evaluate its effectiveness. OBJECTIVE: This study assessed barriers and facilitators to HKTP implementation preparation. METHODS: Interviews and group discussions were conducted with transplant stakeholders (ie administrators, nurses, physicians) during implementation preparation. The Consolidated Framework for Implementation Research (CFIR) guided interview design and qualitative analysis. RESULTS: Forty-four stakeholders participated in 24 interviews and/or 27 group discussions. New factors, not found in previous implementation preparation research in health-care settings, emerged as facilitators and barriers to the implementation of culturally competent care. Implementation facilitators included: stakeholders' focus on a moral imperative to implement the HKTP, personal motivations related to their Hispanic heritage, and perceptions of Hispanic patients' transplant education needs. Implementation barriers included: stakeholders' perceptions that Hispanics' health insurance payer mix would negatively impact revenue, a lack of knowledge about LDKT disparities and patient data disaggregated by ethnicity/race, and a perception that the family discussion component was immoral because of the possibility of coercion. DISCUSSION AND CONCLUSIONS: Our study identified novel barriers and facilitators to the implementation preparation of a culturally competent care intervention. Healthcare administrators can facilitate organizations' implementation of culturally competent care interventions by understanding factors challenging care delivery processes and raising clinical team awareness of disparities in LDKT.

Percutaneous Access of the Modified Hutson Loop for Retrograde Cholangiography, Endoscopy, and Biliary Interventions.

PURPOSE: The purpose of this study was to present the institutional experience of performing endoscopy, cholangiography, and biliary interventions through the modified Hutson loop by interventional radiology. MATERIALS AND METHODS: A total of 61 of 64 modified Hutson loop access procedures were successful. This single-center retrospective study included 61 successful procedures of biliary interventions using existing modified Hutson loops (surgically affixed subcutaneous jejunal limb adjacent to biliary anastomosis or anastomoses) for diagnostic or therapeutic purposes in 21 patients. Seventeen of 21 patients (81%) had undergone liver transplantation. Indications included biliary strictures (n = 18) and biliary leaks (n = 3). The clinical success and complications were evaluated. RESULTS: There were 3 of 26 modified Hutson loop retrograde biliary intervention failures (12%) before introduction of endoscopy and no failures (0 of 38 [0%]) subsequently (P = .06). Endoscopy or cholangioscopy was performed in 19 procedures by interventional radiologists. Retrograde biliary interventions included diagnostic cholangiography (n = 26), cholangioplasty (n = 25), stent placement (n = 29), stent retrieval (n = 25), and biliary drainage catheter placement (n = 5). No procedure-related mortality occurred. There was 1 major complication (duodenal perforation) (1.6%) and 12 minor complications (19%). In the 9 patients undergoing therapeutic interventions for biliary strictures, there was a significant decrease in median alkaline phosphatase (288.5 to 174.5 U/L; P = .03). There was a trend toward decrease in median bilirubin levels (1.7 to 1 mg/dL; P = .06) at 1 month post-intervention. CONCLUSIONS: The modified Hutson loop provided interventional radiologists a safe and effective alternative access to manage biliary complications in patients with biliary-enteric anastomoses. Introduction of the endoscope in interventional radiology has improved the success rate of these procedures.

Bactericidal Effect of Entomopathogenic Bacterium Pseudomonas entomophila Against Xanthomonas citri Reduces Citrus Canker Disease Severity.

The bacterium Pseudomonas entomophila has been recognized as an exceptional species within the Pseudomonas genus, capable of naturally infecting and killing insects from at least three different orders. P. entomophila ingestion leads to irreversible gut damage resulting from a global blockage of translation, which impairs both immune and tissue repair systems in the insect intestine. In this study we isolated a P. entomophila bacterial strain from soil samples which displayed a strong activity against Xanthomonas citri subsp, citri (Xcc), the etiological agent of citrus canker disease. The antagonism potential of isolated bacteria against Xcc and its ability to reduce citrus canker severity was assessed both ex planta and in planta. Our findings show that pathogenicity assays in Citrus x limonia by pressure infiltration and spray with a mixture of P. entomophila and Xcc leaded to a significant reduction in the number of canker lesions in high susceptible citrus leaves, at 21 days post-infection. To the best of our knowledge this is the first report of antibacterial activity of P. entomophila against a phytopathogenic bacterium. Collective action of P. entomophila factors such as diketopiperazine production and the type 6 secretion system (T6SS) may be involved in this type of biological control of citrus canker. The results suggest that the P. entomophila strain could be a promising biocontrol agent acting directly against Xcc.
