Background. Nonalcoholic steatohepatitis (NASH) continues to increase in frequency as an indication for liver transplantation (LT). Data on long-term outcomes for these patients are limited. We aimed to compare long-term patient and graft survival in patients undergoing LT for NASH in the United States to other indications. Methods. We analyzed data from the Scientific Registry of Transplant Recipients of adult patients who underwent primary deceased-donor LT from January 1, 2005, to December 31, 2019. Results. NASH has increased as an indication for LT by 4.5-fold, from 5.2% in 2005 to 23.4% in 2019. Patient (61.2%) and graft survival (59.2%) at 10 y are significantly poorer for NASH than for all other indications other than alcohol. Patients transplanted for NASH have higher body mass index (32.2 versus 27.6) and greater frequency of diabetes (13% versus 11.6%) than any other indication (P < 0.001). Portal vein thrombosis, location in intensive care unit, dialysis, and pre-LT diabetes (P < 0.001 for all) are independently predictive of patient death and graft loss. Body mass index is not predictive. NASH patients undergoing simultaneous liver kidney have markedly worse 10-y patient and graft survival than liver-only (52.3% versus 62.1%). Graft loss was attributed to recurrence of NASH in <1% of patients. Conclusions. LT for NASH is associated with relatively poor long-term patient and graft survival when compared with patients transplanted for other indications, NASH patients undergoing simultaneous liver kidney have the worst long-term outcomes.

The purpose of this study was to conduct a literature review to examine micronutrient deficiencies in laparoscopic sleeve gastrectomy. We conducted a literature review using PubMed and Cochrane databases to examine micronutrient deficiencies in SG patients in order to identify trends and find consistency in recommendations. Seventeen articles were identified that met the defined criteria. Iron, vitamin B12 and vitamin D were the primary micronutrients evaluated. Results demonstrate the need for consistent iron and B12 supplementation, in addition to a multivitamin, while vitamin D supplementation may not be necessary. Additional prospective studies to establish a clearer picture of micronutrient deficiencies post-SG are needed.

data from 1086 procedure reports from the six months prior to implementation and 1270 procedure reports from the six months after implementation were reviewed to assess changes in code usage. Results: Structured reporting increased the number of CPT codes per procedure (2.93 vs 3.90, p<0.01). Structured reporting increased the use of codes for fluoroscopic guidance for central venous catheter placement, ultrasound guidance for vascular access, time-based moderate sedation, and 3D rendering with interpretation (165 vs 343, 442 vs 1326, 273 vs 460, and 0 vs 10; p<0.01). Structured reporting had no significant impact on the usage of other codes like selective catheterization (120 vs 128). Conclusions: Implementation of mandatory structured reports for interventional radiology procedures increases the number of codes per report and increases usage of codes requiring documentation of specific criteria. Abstract No. 571Effective dose comparison between computed tomography-versus fluoroscopy-guided bone marrow biopsies Purpose: Bone marrow biopsies are an established diagnostic tool, with the first diagnostic biopsy in 1903. While bone marrow biopsy can be done at the bed side, image guidance with computedtomography-guided biopsies (CTB) and fluoroscopic-guided biopsies (FB) have been used with increasing frequency. CTB and FB have increased the accuracy of biopsies and decreased complications. This study delineates the effective dose (ED) difference between the two techniques. Materials: This retrospective study utilizes the medical record of patients who have had CTB or FB of the iliac crest. Data was gathered at three clinical sites. A total of 44 patients were selected randomly and split between CTB and FB. CTG had 9 female and 13 male patients, 22-86 years of age. FB had 17 female and 6 male patients, 25-77 years of age. Dose area product (DAP) for FB or dose length product (DLP) for CTB were obtained from the source images. DLP for CTB was estimated from the appropriate (16 or 32 cm) imaging phantom and converted to ED using the pelvis K-value 0.015 mSv/gycm. For FB, the kyphoplasty of the lumbar spine K-value 0.2 mSv/gycm 2 was used. ED was compared between CTB and FB using the Mann-Whitney test. Results: ED was significantly smaller for FB compared to CTB (p<0.0001). The mean ED value for CTB was 5.4 mSv (range of 0.46 to 15.9 mSv, n¼22, SD of 3.5). The mean ED value for FB was 0.28 mSv (range of 0.007 to 2.05 mSv, n¼22, SD of 0.47). Conclusions: The findings show that there is significantly less ED in FB compared to CTB. This information may be useful in reducing radiation exposure to patients undergoing image-guided bone marrow biopsies.
