Abstract
Background Anatomic abnormalities increase the risk of deceased donor kidney discard, but their effect on transplant outcomes is understudied. We sought to determine the effect of multiple donor renal arteries on early outcomes after deceased donor kidney transplantation. Methods For this retrospective cohort study, we identified 1443 kidneys from 832 deceased donors with ≥1 kidney transplanted at our center (2006-2016). We compared the odds of delayed graft function and 90-day graft failure using logistic regression. To reduce potential selection bias, we then repeated the analysis using a paired-kidney cohort, including kidney pairs from 162 donors with one single-artery kidney and one multiartery kidney. Results Of 1443 kidneys included, 319 (22%) had multiple arteries. Multiartery kidneys experienced longer cold ischemia time, but other characteristics were similar between groups. Delayed graft function (50% multiartery versus 45% one artery, P=0.07) and 90-day graft failure (3% versus 3%, P=0.83) were similar between groups before and after adjusting for donor and recipient characteristics. In the paired kidney analysis, cold ischemia time was significantly longer for multiartery kidneys compared with single-artery kidneys from the same donor (33.5 versus 26.1 hours, P<0.001), but delayed graft function and 90-day graft failure were again similar between groups. Conclusions Compared with single-artery deceased donor kidneys, those with multiple renal arteries are harder to place, but experience similar delayed graft function and early graft failure.

Abstract
Coronavirus disease 2019 (COVID‐19) has become a pandemic since first being described in January 2020. Clinical manifestations in non‐transplant patients range from asymptomatic infection to severe pneumonia with acute respiratory distress syndrome, multiorgan system failure, and death. Limited reports in kidney transplant recipients suggest similar characteristics in that population. We report here the first case series of COVID‐19 infection occurring in pancreas transplant recipients.

Abstract
We sought to review our kidney transplant biopsy experience to assess the incidence, type, presenting symptoms, and timing of renal transplant biopsy complications, as well as determine any modifiable risk factors for postbiopsy complications. This is an observational analysis of patients at the University of Wisconsin between January 1, 2000, and December 31, 2009. Patients with an INR ≥1.5 or platelet counts less than 50 000 were not biopsied. An 18-gauge needle was used for biopsy. Over the study period, 3738 biopsies were performed with 66 complications (1.8%). No deaths occurred. A total of 0.7% were mild complications, 0.7% were moderate complications, 0.21% were severe complications, and 0.19% were life-threatening. Most complications occurred within the 4-h postbiopsy period, although serious complications were often delayed: 67% of complications requiring surgical intervention presented greater than 4 h after biopsy. Biopsy within 1 week of transplant had a 311% increased risk of a complication. Postbiopsy reduction in hematocrit and hemoglobin at 4 h was associated with a complication. In conclusion, life-threatening complications after renal allograft biopsy occurred in 0.19% of patients. Most complications occurred within 4 h postprocedure; however, many serious complications occurred with a time delay after initially uneventful monitoring. The only clinically significant laboratory predictor of a complication was a fall in the hematocrit or hemoglobin within 4 h. Patients biopsied within a week of transplant were at the highest risk for a complication and should therefore be most closely monitored.

Abstract
Abstract #3029
Background: Luminal type A and type B represent estrogen receptor alpha (ERalpha)-positive breast cancers with luminal type A expressing higher levels of ERalpha and is associated with better prognosis. Recent studies have identified a specific functional transcription factor network comprising GATA-3, FOXA1 and ERalpha in normal luminal cells as well as in luminal type A breast cancer that dictates their hormone dependence. Signaling molecules that may disrupt this network and force these cells to acquire hormone-independence are not known. T-bet (Tbx21) has been described as a major negative regulator of GATA-3 activity. As the expression and/or activity of some of the above factors are controlled by insulin, the objective of this study was to investigate whether elevated level of insulin, as evidenced in type II diabetes, alters gene expression pattern in luminal type A breast cancers by interrupting GATA-3:FOXA1:ERalpha network and thus forcing these cancers to acquire non-luminal phenotype and/or hormone-independence.
 Methodologies: The effect of insulin on the expression of ERalpha, FOXA1, GATA-3 and T-bet was measured in ERalpha-positive MCF-7 cells by Western blot analysis. The effect of T-bet on estrogen-regulated gene expression was measured by stable overexpression of T-bet in MCF-7 cells and subsequent qRT-PCR analysis. Publicly available Oncomine database was used to determine the expression pattern of T-bet and its relation to ERalpha status in primary breast cancers. A proliferation assay was used to determine sensitivity of T-bet overexpressing cells to tamoxifen in the presence and absence of insulin.
 Results: Insulin induced the expression of T-bet, which was partially reversed by estrogen. ERalpha and GATA-3 levels were reduced in MCF-7 cells stably overexpressing T-bet suggesting that T-bet reduces GATA-3-dependent ERalpha expression. Estrogen-inducible expression of estrogen target genes GREB-1 and Myb was lower in T-bet overexpressing cells compared to parental cells, although basal expression was elevated in T-bet overexpressing cells. Treatment of T-bet overexpressing cells with insulin decreased tamoxifen sensitivity. Although T-bet expression was generally higher in ERalpha-negative breast cancers compared to ERalpha-positive breast cancers, a subpopulation of ER-positive breast cancers express elevated levels of T-bet.
 Conclusions: Insulin may change the gene expression pattern through T-bet-mediated disruption of master cell-type-specific transcriptional network including GATA-3, ERalpha and FOXA1 that dictates the phenotype of hormone-dependent luminal type A breast cancer. T-bet may serve as a marker to identify ERalpha-positive breast cancers that express low levels of GATA-3 and have progressed to hormone-independence.
