A Review of the Psychology That Underpins the Creation of a Diversity, Equity, and Inclusion Committee.

Although all committee work can be fraught with difficulty and laborious time commitments, committees designed to disrupt the cycle of inequity and bias are particularly fraught with social and emotional land mines that come as baggage to years of unaddressed inequity. As such, leaders must take special care and attend to the complex psychology that underpins the difficult discussions that must be had by these committees as they begin to address topics of inequity within professional medical institutions. The authors describe, in an accessible summary format, how to lay the foundations for a smooth transition into the work of a diversity, equity, and inclusion committee, the best steps to build a team, and the core concepts that should underpin all diversity, equity, and inclusion work, starting from the intrapersonal level and moving toward the organizational level. This is done with the help of available scientific data where they are available, including literature on teamwork, health equity, and psychological safety, among other topics.

Improving Outcomes after Allograft Nephrectomy through Use of Preoperative Angiographic Kidney Embolization.

BACKGROUND: Allograft nephrectomy (AN) has been associated with considerable perioperative morbidity. We aimed to determine if preoperative angiographic kidney embolization (PAKE) to induce graft thrombosis before AN improves outcomes. STUDY DESIGN: We reviewed adult kidney transplant alone patients who underwent AN at a single center from 2002 to 2020 and compared perioperative outcomes for patients with and without PAKE. RESULTS: Eighty patients underwent AN, including 54 (67.5%) with PAKE before AN and 26 (32.5%) with AN alone. PAKE was associated with significantly reduced blood loss (PAKE: mean 266 ± 292 mL vs AN alone: 495 ± 689 mL; p = 0.04) and reduced transfusion requirements (PAKE: mean 0.5 ± 0.8 packed red blood cell units vs AN alone: 1.6 ± 2.6 units; p = 0.004) despite similar preoperative hemoglobin levels. Mean operating time (PAKE: 142 ± 43 minutes vs AN alone: 202 ± 111 minutes; p = 0.001) and length of hospital stay (PAKE: 4.3 ± 2.0 days vs AN alone: 9.3 ± 9.4 days; p = 0.0003) also favored PAKE, as did the surgical complication rate (PAKE: 6/54 [11%] vs AN alone: 9/26 [35%], p = 0.02). Long-term patient survival after AN was comparable in both groups. CONCLUSIONS: PAKE was associated with lower intraoperative blood loss, fewer transfusions, reduced operating time, shorter length of stay, and fewer surgical complications compared with AN alone at our center.

Outcomes of radioembolization for unresectable hepatocellular carcinoma in patients with marginal functional hepatic reserve.

PURPOSE: To evaluate the outcomes of radioembolization (RE) as a therapy for unresectable hepatocellular carcinoma (HCC) in patients with marginal functional hepatic reserve. METHODS: A retrospective review of 471 patients (1/2010-7/2015) treated with RE (Therasphere, BTG, UK) was performed. A total of 36 patients (mean age: 66.1±9.3, male: 86.1%) underwent therapy for HCC with a MELD≥15 (median: 16, range: 15-22). Baseline demographics of the study cohort were as follows: etiology (HCV: 26, 72.2%), cirrhosis (n=32, 88.9%), ECOG 0 (n=16, 44.4%), Child-Pugh class (A=15, B=19, C=2), unilobar distribution (n=27, 75%), AFP>200 (n=11, 30.6%), portal vein thrombosis (PVT, n=7, 19.4%), metastasis (n=3, 8.3%). Outcomes analyzed included CTCAEv4.03 laboratory toxicities (120-day), imaging response (mRECIST), progression-free survival (PFS), and overall survival (OS). RESULTS: A total of 42 treatments were performed with mean dose of 2.02±1.23GBq. The cumulative grade 3/4 toxicity was 28% overall and 21% for bilirubin at 120-days. The objective response and disease control rates were 48.3% (14/29) and 69% (20/29) respectively. The median (95% CI) PFS was 5.9 (4.4-7.7) months. Ten (27.8%) patients received additional locoregional therapy at a median (IQR) of 138 (102-243) days post RE. The mean (95% CI) OS was 21.9 (14.8-29.0) months. The absence of PVT was associated with improved OS (p=0.005) Disease control at 90-days was also associated with an OS benefit (p=0.037). CONCLUSIONS: Patients with unresectable HCC and marginal functional hepatic reserve treated with RE had favorable objective response and disease control rates, both predictive of overall survival.

Radiation Segmentectomy versus TACE Combined with Microwave Ablation for Unresectable Solitary Hepatocellular Carcinoma Up to 3 cm: A Propensity Score Matching Study.

Purpose To compare the outcomes of radiation segmentectomy (RS) and transarterial chemoembolization (TACE) combined with microwave ablation (MWA) in the treatment of unresectable solitary hepatocellular carcinoma (HCC) up to 3 cm. Materials and Methods This retrospective study was approved by the institutional review board, and the requirement to obtain informed consent was waived. From January 2010 to June 2015, a total of 417 and 235 consecutive patients with HCC underwent RS and TACE MWA, respectively. A cohort of 121 patients who had not previously undergone local-regional therapy (RS, 41; TACE MWA, 80; mean age, 65.4 years; 84 men [69.4%]) and who had solitary HCC up to 3 cm without vascular invasion or metastasis was retrospectively identified. Outcomes analyzed included procedure-related complications, laboratory toxicity levels, imaging response, time to progression (TTP), 90-day mortality, and survival. Propensity score matching was conducted by using a nearest-neighbor algorithm (1:1) to account for pretreatment clinical, laboratory, and imaging covariates. Postmatching statistical analysis was performed with conditional logistic regression for binary outcomes and the stratified log-rank test for time-dependent outcomes. Results Before matching, the complication rate was 8.9% and 4.9% in the TACE MWA and RS groups, respectively (P = .46). The overall complete response (CR) rate was 82.9% for RS and 82.5% for TACE MWA (odds ratio, 1.0; 95% confidence interval [CI]: 0.4, 2.8; P = .95). There were 41 (RS, 11; TACE MWA, 30) instances of progression occurring after an initial CR, of which 10 (24%) were classified as target progression (RS, one; TACE MWA, nine). Median overall TTP was 11.1 months (95% CI: 8.8 months, 25.6 months) in the RS group and 12.1 months (95% CI: 7.7 months, 19.1 months) in the TACE MWA group (P > .99). After matching, the overall CR rate (P = .94), TTP (P = .83), and overall survival (P > .99) were not significantly different between the two groups. The 90-day postoperative mortality rate was 0% in both groups. Conclusion Imaging response and progression outcomes of patients with solitary HCC up to 3 cm treated with RS were not significantly different when compared with those of patients treated with TACE MWA. © RSNA, 2016 Online supplemental material is available for this article.

Radiation dose reduction utilizing noise reduction technology during uterine artery embolization: a pilot study.

OBJECTIVE: To assess the radiation dose reduction during uterine artery embolization utilizing dose reduction technology. METHODS: A total of 58 women underwent uterine artery embolization. A total of 26 procedures were performed in a standard fluoroscopy suite; 32 procedures were performed utilizing a novel imaging platform. Radiation dose data and acquisition parameters were compared. RESULTS: The new platform provided significant reduction in the median radiation dose (P<.001): from 389Gy cm(2) to 145Gy cm(2). There were no differences between the groups with regard to acquisition parameters. CONCLUSION: The new imaging platform provided a 61% dose reduction during uterine artery embolization without a significant change in acquisition parameters.
