Nineteen percentage of patients with inflammatory bowel disease treated at a referral center are readmitted within 30 days. Our results suggest that patients with comorbid medical conditions, malnutrition or obesity, a new ileostomy, past steroid use, or those discharged on hyperalimentation are at increased risk for readmission. Research is needed to determine if targeted interventions for high-risk patients decreases readmissions.

A large repository of cryopreserved peripheral blood mononuclear cells (PBMCs) samples was created to provide laboratories testing the specimens from human immunodeficiency virus-1 (HIV-1) vaccine clinical trials the material for assay development, optimization, and validation. One hundred thirty-one PBMC samples were collected using leukapheresis procedure between 2007 and 2013 by the Comprehensive T cell Vaccine Immune Monitoring Consortium core repository. The donors included 83 human immunodeficiency virus-1 (HIV-1) seronegative and 32 HIV-1 seropositive subjects. The samples were extensively characterized for the ability of T cell subsets to respond to recall viral antigens including cytomegalovirus, Epstein– Barr virus, influenza virus, and HIV-1 using Interferon-gamma (IFN-γ) enzyme linked immunospot (ELISpot) and IFN-γ/interleukin 2 (IL-2) intracellular cytokine staining (ICS) assays. A subset of samples was evaluated over time to determine the integrity of the cryopreserved samples in relation to recovery, viability, and functionality. The principal results of our study demonstrate that viable and functional cells were consistently recovered from the cryopreserved samples. Therefore, we determined that this repository of large size cryopreserved cellular samples constitutes a unique resource for laboratories that are involved in optimization and validation of assays to evaluate T, B, and NK cellular functions in the context of clinical trials.

Abstract Background Serum drug-level assays for infliximab (IFX) and adalimumab (ADA) are widely available and are most often obtained reactively, to determine the next steps in patients with loss of response. Studies done thus far on the use of these assays proactively, or during symptom remission, have had mixed results. Here we investigate persistence on therapy and healthcare utilization in patients on 3 drug-level monitoring strategies. Methods We conducted a retrospective chart review of 235 patients treated for both Crohn disease and ulcerative colitis on either IFX or ADA. Monitoring strategy was defined as proactive if patients underwent testing at predefined time points regardless of symptoms or signs of disease, reactive if done during relapse, or control if no drug levels were obtained. Groups were compared on persistence on original therapeutic at 1 and 2 years as well as on various measures of healthcare utilization during the 2-year follow-up period. Results Proactive drug monitoring was associated with a higher likelihood of persistence on therapy at 1 year when compared with the control (odds ratio [OR] = 4.76, 95% confidence interval [CI] = 1.65, 13.67) and reactive groups (OR = 6.10, CI = 2.19, 17.02). Similarly, at 2 years, proactive monitoring was superior to the control (OR = 5.41, CI = 2.26, 12.94) and reactive groups (OR = 4.51, CI = 1.88, 10.80). Proactive monitoring was also associated with lower healthcare utilization across almost all measures related to inflammatory bowel disease. Conclusions Proactive drug monitoring increases persistence on IFX and ADA in patients with ulcerative colitis or Crohn disease and decreases overall healthcare utilization in these patients.

Due to the rapidly evolving nature of this outbreak, and in the interests of rapid dissemination of reliable, actionable information, this paper went through expedited peer review. Additionally, information should be considered current only at the time of publication and may evolve as the science develops.

Background. Multiple listing (ML) at >1 transplant center is one mechanism to combat the geographic disparities in liver transplantation (LT) rates. The objective of our study was to determine the impact of multiple listing on LT rates. Methods. We examined the United Network of Organ Sharing database from 2002 to 2016 after excluding those listed for multiple organs, hepatocellular carcinoma, or living donor LT. The waitlist mortality and LT rates for the ML groups and the single listed (SL) group were compared after stratifying patients by the Model for End-Stage Liver Disease (MELD) with a cutoff at 15 (<15 and ≥15). Results. Of the 83 935 listed during the study period, 80 351 were listed in a single center (SL group), and 3584 were listed in >1 center (ML group). Of the ML groups, 2028 (2.4%) were listed at multiple donor service areas but within the same region (ML-SR) and 1556 (1.9%) listed in different regions (ML-DR). The median MELD at LT was 20, 21, and 24 for ML-DR, ML-SR, and SL groups, respectively (P = 0.001). Although the probability of receiving LT was significantly higher for the ML groups relative to the SL group for both MELD groups (<15 and ≥15), the impact was the highest for ML-DR group. At MELD score <15, the probability of LT was 72% for ML-DR, 38% for ML-SR, and 32% for SL groups. At MELD score ≥15, the probability of LT was 79% for ML-DR, 67% for ML-SR, and 61% for SL groups. Conclusions. Multiple listing appeared to considerably improve a patient’s chance of receiving LT and survival with the highest benefit for those with low MELD scores (<15) listed at multiple regions.

BaCKgRoUND aND aIMS: Thirty percent of patients with cirrhosis are obese and the prevalence of obesity increases after transplant to >40% post-transplant. There are currently four weight loss medications approved by the FDA for treatment of obesity (orlistat, phentermine-topiramate, naltrexone-bupropion, and liraglutide). The aim of this review was to investigate the data on the use of these weight loss medications and alternative medicines in patients with cirrhosis and in liver transplant recipients (LTRs). appRoaCH aND ReSUltS: While there is paucity of data for these medications in patients with cirrhosis and LTRs, Liraglutide appears to be generally safe in view of its pharmacokinetic properties. Phentermine-topiramate seems to have the highest weight loss potential but special consideration should be given to neuropsychiatric disorders, cardiovascular comorbidities, and drug interactions. There are emerging data on use of alternative medicines for weight loss but more data are needed. CoNClUSIoNS:The use of weight loss medications is feasible in this patient population but the decision of which medication to prescribe should be individualized based on the degree of renal and hepatic impairment, other co-morbidities, and concomitant medications. (Hepatology 2021;73:2051-2062.O besity is estimated to affect 40% of the United States population and is associated with hepatic, metabolic and cardiovascular morbidities as well as certain cancers and premature death. (1,2) Thirty percent of patients with cirrhosis are obese, while 40% are overweight, and recent analysis of national registry data revealed that 35.9% of adult liver-transplant recipients (LTRs) were obese at the time of transplant. (2,3) In a retrospective study, obesity increased from 23.8% at 4 months to 40.8% 3 years after transplant. (4) Obesity and other components of metabolic syndrome are closely associated with development of NASH, which has become the most common indication for transplantation in women and the second most common indication in men. (5,6) About half of LTRs meet the criteria for metabolic syndrome, placing them at significant risk for long-term cardiovascular and metabolic complications. (7) Weight loss is associated with improvement in NASH and portal hypertension as well as longterm favorable outcomes in general population. (8)(9)(10) Weight loss may enhance future transplant eligibility of patients with cirrhosis and morbid obesity. The parallel increase in prevalence of NASH cirrhosis and obesity highlights the importance of finding a weight-loss strategy that is safe and effective in cirrhosis and LTRs. The data for weight loss-related
