In spite of significant advancement in HCC management, its incidence continues to rise. There remains an urgent need to continue refining understanding of HCC and develop strategies to increase utilization of the available preventive measures and curative treatment modalities for HCC.

Background: To define urine or serum biomarkers in predicting renal function recovery after liver transplantation (LT). Methods: Adults listed for LT (February 2011-July 2014) and with modified diet for renal disease-6 (MDRD-6) <60 mL/min provided urine/blood samples at baseline and serially until LT for biomarkers in serum (pg/mL) and urine (pg/mg creatinine). Results: Of 271 LT listed patients (mean age 57 years, 63% males, median listing MELD 17.5), 1 year acute kidney injury (AKI) probability was 49%, with odds of 1.3-, 3.0-, 4.6-, and 8.5-fold times for listing MELD 16-20, 21-25, 26-30, and >30, compared to MELD <16. Thirty-seven people died over 1 year from the time of listing, with twofold increased odds with AKI. Among 67 patients with MDRD <60, only urinary epidermal growth factor was different comparing AKI (increase in serum creatinine ≥0.3 mg/dL from baseline within past 3 months) vs. no AKI (2,254 vs. 4,253, p = 0.003). Differences between acute tubular necrosis (ATN) and hepatorenal syndrome could not be ascertained for a small sample of 3 patients with ATN. Analyzing 15 of 43 receiving LT and MDRD-6 <30 prior to LT, biomarkers were not different comparing 5 patients recovering renal function (MDRD-6 >50 mL/min) at 6 months vs. 10 without recovery. Conclusions: AKI is common among LT listed patients, with a negative impact on transplant-free survival. Serum and urine biomarkers are not associated with the recovery of renal function after LT. Multicenter studies are suggested to (a) develop strategies to reduce the development of AKI and (b) derive novel biomarkers for use in accurately predicting renal recovery after LT.

Background/Aims: Recent studies suggest that markers of mesenteric inflammation, such as increased adipose tissue, may be associated with poor outcomes in Crohn's disease (CD). This study's hypothesis is that CD patients with metabolic syndrome (MetS) have more CD-related hospitalizations than CD patients without MetS. Methods: We conducted a retrospective cohort study of CD patients seen from 2000 to 2012 at our tertiary care center. We analyzed crude and age-, sex- and duration of CD-adjusted incidence rate ratio (IRR) of CD-related hospitalization of those with MetS versus those without MetS. We also investigated possible associations between individual component conditions of MetS and rate of CD-related hospitalization. Results: A total of 868 CD patients were included. There were 37 (4%) patients with MetS at initial observation. After multi-variable adjustment, patients with MetS had a CD-related hospitalization rate twice that of those who did not have MetS. High triglycerides (TG), low high density lipoprotein (HDL) cholesterol and diabetes mellitus (DM) were associated with increased risk of CD-related hospitalization. Conclusions: CD patients with MetS have a higher rate of CD-related hospitalization compared to those without MetS. Hypertriglyceridemia, low HDL cholesterol and DM may be good markers of local and systemic inflammation as seen in CD.

Though DAAs have eliminated many historically, long-standing medical barriers to HCV treatment, several racial, psychological and socioeconomic barriers, and disparities remain. Consequently, patients who are African American, uninsured, and actively use drugs and alcohol will suffer from increased HCV-related morbidity and mortality in the coming years if deliberate public health and clinical efforts are not made to facilitate access to DAAs.

Racial disparities are observed clinically in Crohn’s Disease (CD) with research suggesting African Americans (AA) have worse outcomes than Caucasian Americans (CA). The aim of this study is to assess whether socioeconomic status (SES) rather than race is the major predictor of worse outcomes. We designed a retrospective cohort study of 944 CD patients seen at our center. Patients’ billing zip codes were collected and average income and percent of population living above or below poverty level (PL) for each zip code calculated. Patients were separated by quartiles using average state income level and federal PL. Demographics and hospitalization rates were collected. Poison regression models estimated incidence rate ratios (IRR) for CD-related hospitalizations. Incidence rate (IR) of hospitalization per 100-person years for the lowest income group was 118 (CI 91.4–152.3), highest income group was 29 (CI 21.7–38.9), Above PL was 26.9 (25.9–28.9), Below PL was 35.9 (33.1–38.9), CA was 25.3 (23.7–27), and AA was 51.4 (46.8–56.3). IRR for a CD-related hospitalization for lowest income group was 2.01 (CI 1.34–3.01), for Below PL was 1.26 (CI 1.12–1.42), and for AAs was 1.88 (CI 1.66–2.12). SES and race are both associated with hospitalization among CD patients and need further investigation.

Gastrointestinal bleeding (GIB) is common in patients with continuous-flow left ventricular assist devices (CF-LVADs) possibly because of changes in blood flow. We aimed to test the hypothesis that a low pulsatility index (PI) is associated with an increased hazard of overt GIB in patients with CF-LVADs. We conducted a retrospective cohort study of patients who had a HeartMate II (HMII) CF-LVAD implanted at our center. The study end-point was the first overt GIB causing or occurring during a hospitalization between 6 days and 6 months after HMII implantation. HMII PI was recorded at 48 hours and at 1, 3, and 6 month intervals after implantation. We analyzed the associations of PI and clinical variables with the hazard of overt GIB. Ninety-five patients met eligibility criteria. PI ranged from 2.5 to 5.9 (low PI < 4.15 and high PI ≥ 4.15 on the basis of receiver operating characteristic curve analysis). Seventeen (18%) patients experienced overt GIB. In a multivariable model, only lower baseline hemoglobin was a significant predictor of an increased hazard of overt GIB. After adjusting for the baseline hemoglobin, low PI was independently associated with an increased hazard of overt GIB in our cohort of HMII recipients.
