Implementation of a National Liver Review Board for exception requests in the United States: A 2-year monitoring report.

The exception point system for liver allocation in the United States allows for additional waitlist priority for candidates where the Model for End-Stage Liver Disease or Pediatric End-stage Liver Disease does not effectively represent their urgency or need for a transplant. In May 2019, the review process for liver exception cases transitioned from 11 Regional Review Boards (RRBs) to 1 National Liver Review Board (NLRB), intended to increase consistency nationwide, improve efficiency, and balance transplant access for candidates with and without exception scores. This report provides a review of liver exception request and review practices, waitlist outcomes, and transplant activity in the first 2 years after implementation of the NLRB and acuity circle-based distribution in the United States. We compared initial and extension exception request forms submitted from May 13, 2017 to May 13, 2019 (prepolicy or RRB era) to the period from February 4, 2020 to February 3, 2022 (postpolicy or NLRB era). During this time, the NLRB reviewed 10,083 initial exception requests and 12,686 extension requests. Notable postpolicy highlights include (1) an increase in the proportion of initial and extension requests that were automatically approved instead of manually reviewed; (2) a decrease in the overall approval rates of initial exception requests (87.8% for adult HCC, 64.3% for adult other diagnoses, and 71.5% for pediatric); and (3) reduction in the time from exception request submission to adjudication to a median of 3.73 days. The proportions of waitlist registration and deceased donor liver transplants for patients with exception scores decreased, and waitlist outcomes between patients with and without exception scores are now comparable. Implementation of the NLRB improved efficiency, reduced case workloads, and standardized criteria for exception cases, with similar waitlist outcomes between patients with and without exception scores and improved equity in terms of access to liver transplants.

Colder Weather and Fewer Sunlight Hours Increase Alcohol Consumption and Alcoholic Cirrhosis Worldwide.

Risk of alcoholic cirrhosis is determined by genetic and environmental factors. We aimed to investigate if climate has a causal effect on alcohol consumption and its weight on alcoholic cirrhosis. We collected extensive data from 193 sovereign countries as well as 50 states and 3,144 counties in the United States. Data sources included World Health Organization, World Meteorological Organization, and the Institute on Health Metrics and Evaluation. Climate parameters comprised Koppen-Geiger classification, average annual sunshine hours, and average annual temperature. Alcohol consumption data, pattern of drinking, health indicators, and alcohol-attributable fraction (AAF) of cirrhosis were obtained. The global cohort revealed an inverse correlation between mean average temperature and average annual sunshine hours with liters of annual alcohol consumption per capita (Spearman's rho -0.5 and -0.57, respectively). Moreover, the percentage of heavy episodic drinking and total drinkers among population inversely correlated with temperature -0.45 and -0.49 (P < 0.001) and sunshine hours -0.39 and -0.57 (P < 0.001). Importantly, AAF was inversely correlated with temperature -0.45 (P < 0.001) and sunshine hours -0.6 (P < 0.001). At a global level, all included parameters in the univariable and multivariable analysis showed an association with liters of alcohol consumption and drinkers among population once adjusted by potential confounders. In the multivariate analysis, liters of alcohol consumption associated with AAF. In the United States, colder climates showed a positive correlation with the age-standardized prevalence of heavy and binge drinkers. Conclusion: These results suggest that colder climates may play a causal role on AAF mediated by alcohol consumption.

Alcohol-Related Liver Disease Is Rarely Detected at Early Stages Compared With Liver Diseases of Other Etiologies Worldwide.

BACKGROUND & AIMS: Despite recent advances in treatment of viral hepatitis, liver-related mortality is high, possibly owing to the large burden of advanced alcohol-related liver disease (ALD). We investigated whether patients with ALD are initially seen at later stages of disease development than patients with hepatitis C virus (HCV) infection or other etiologies. METHODS: We performed a cross-sectional study of 3453 consecutive patients with either early or advanced liver disease (1699 patients with early and 1754 with advanced liver disease) seen at 17 tertiary care liver or gastrointestinal units worldwide, from August 2015 through March 2017. We collected anthropometric, etiology, and clinical information, as well as and model for end-stage liver disease scores. We used unconditional logistic regression to estimate the odds ratios for evaluation at late stages of the disease progression. RESULTS: Of the patients analyzed, 81% had 1 etiology of liver disease and 17% had 2 etiologies of liver disease. Of patients seen at early stages for a single etiology, 31% had HCV infection, 21% had hepatitis B virus infection, and 17% had nonalcoholic fatty liver disease, whereas only 3.8% had ALD. In contrast, 29% of patients seen for advanced disease had ALD. Patients with ALD were more likely to be seen at specialized centers, with advanced-stage disease, compared with patients with HCV-associated liver disease (odds ratio, 14.1; 95% CI, 10.5-18.9; P < .001). Of patients with 2 etiologies of liver disease, excess alcohol use was associated with 50% of cases. These patients had significantly more visits to health care providers, with more advanced disease, compared with patients without excess alcohol use. The mean model for end-stage liver disease score for patients with advanced ALD (score, 16) was higher than for patients with advanced liver disease not associated with excess alcohol use (score, 13) (P < .01). CONCLUSIONS: In a cross-sectional analysis of patients with liver disease worldwide, we found that patients with ALD are seen with more advanced-stage disease than patients with HCV-associated liver disease. Of patients with 2 etiologies of liver disease, excess alcohol use was associated with 50% of cases. Early detection and referral programs are needed for patients with ALD worldwide.

Wideband radiofrequency pulse sequence for evaluation of myocardial scar in patients with cardiac implantable devices.

Background: Cardiac magnetic resonance is a useful clinical tool to identify late gadolinium enhancement in heart failure patients with implantable electronic devices. Identification of LGE in patients with CIED is limited by artifact, which can be improved with a wide band radiofrequency pulse sequence. Objective: The authors hypothesize that image quality of LGE images produced using wide-band pulse sequence in patients with devices is comparable to image quality produced using standard LGE sequences in patients without devices. Methods: Two independent readers reviewed LGE images of 16 patients with CIED and 7 patients without intracardiac devices to assess for image quality, device-related artifact, and presence of LGE using the American Society of Echocardiography/American Heart Association 17 segment model of the heart on a 4-point Likert scale. The mean and standard deviation for image quality and artifact rating were determined. Inter-observer reliability was determined by calculating Cohen's kappa coefficient. Statistical significance was determined by T-test as a p {less than or equal to} 0.05 with a 95% confidence interval. Results: All patients underwent CMR without any adverse events. Overall IQ of WB LGE images was significantly better in patients with devices compared to standard LGE in patients without devices (p = 0.001) with reduction in overall artifact rating (p = 0.05). Conclusion: Our study suggests wide-band pulse sequence for LGE can be applied safely to heart failure patients with devices in detection of LV myocardial scar while maintaining image quality, reducing artifact, and following routine imaging protocol after intravenous gadolinium contrast administration.

Patient-reported symptoms and interest in symptom monitoring in HCC treated with locoregional therapies: A qualitative study.

BACKGROUND: Patient-reported outcomes (PRO) measures relevant to domains most important to patients with HCC who received locoregional therapies are needed to advance patient-centered research. Furthermore, electronic PRO monitoring in clinical care has been shown to reduce hospitalizations and deaths in patients with other cancers. We conducted a qualitative study among patients with HCC who recently received locoregional therapies to (1) identify common and distressing posttreatment symptoms to prioritize PRO domain selection and (2) gauge interest in an electronic PRO symptom monitoring system. METHODS: We performed semi-structured telephone interviews among adult patients who received locoregional therapies (median of 26 days after treatment) for treatment-naïve HCC at a single tertiary care center. Interviews were conducted until thematic saturation was reached. Qualitative content analysis was conducted to identify emerging themes and sub-themes. RESULTS: Ten of 26 patients (38%) reported at least 1 symptom before treatment. In contrast, all participants (n = 26) with recently treated HCC reported at least 1 posttreatment physical symptom, with the most common being appetite loss (73%), fatigue (58%), abdominal pain (46%), and nausea (35%). Most participants (77%) stated they saw potential benefits in posttreatment ePRO symptom monitoring. CONCLUSIONS: Posttreatment symptoms after HCC locoregional therapies are common and often severe. These data can inform and prioritize PRO domain selection. Patients are interested in ePRO monitoring to monitor and proactively address posttreatment symptoms. Given the clinical benefits in patients with metastatic cancers, ePRO monitoring warrants investigation in patients with HCC.

Nutrition as Therapy in Liver Disease.

PURPOSE: The importance of nutrition is often underrecognized in the routine clinical care of patients with chronic liver disease. Nutrition therapy plays a significant role in the management of alcohol-related liver disease and nonalcoholic fatty liver disease. In patients with cirrhosis from any etiology, malnutrition and sarcopenia are directly related to mortality, and nutritional interventions play an important role in the management of these patients. This review explores the role of nutritional intervention as adjuvant therapy across all chronic liver disease. METHODS: A narrative, qualitative systematic review was performed via searches of PubMed for nutritional aspects in the care of chronic liver disease. FINDINGS: Nutritional therapy plays a critical role in the management of chronic liver disease. In nonalcoholic fatty liver disease, specific macronutrient management can lead to weight loss and improved outcomes in these patients. In patients with alcohol-related liver disease, chronic cholestatic liver disease, and decompensated cirrhosis, caloric and protein intake plays a vital role improving outcomes in these patients. Micronutrient deficencies are also common in these patients and require supplementation to prevent other complications of malnutrition. Assessment and management of nutrition should accompany the typical care plan of patients with chronic liver disease. IMPLICATIONS: This review of nutritional therapy in chronic liver disease highlights the current evidence-based and societal recommendations of macronutrient and micronutrient management across the spectrum of all chronic liver disease.

This case highlights the wide variation in the presentation of cardiac amyloidosis, and the rare occurrence of clinically significant light-chain and heavy-chain amyloidosis in the pericardium. (Level of Difficulty: Advanced.).

Endoscopic ultrasound and the liver: current applications and beyond.

The diagnosis and management of many gastrointestinal conditions has been augmented by the development of endoscopic ultrasound. Its role in the diagnosis and management of liver disease has been somewhat limited, but with the rapid development of therapeutic advancements it has quickly emerged as a useful tool in the management of complex hepatic conditions. This includes its use in the management of complications of portal hypertension as well as its use in liver lesions and cancer. In this paper, we review case studies, case series and trials for hepatic applications of endoscopic ultrasound to provide an overview of its utilization in this field and demonstrating its more novel applications for future use.

Colonic epithelial miR-31 associates with the development of Crohn's phenotypes.

BACKGROUND: Crohn's disease (CD) is highly heterogeneous, due in large part to variability in cellular processes that underlie the natural history of CD, thereby confounding effective therapy. There is a critical need to advance understanding of the cellular mechanisms that drive CD heterogeneity. METHODS: We performed small RNA sequencing of adult colon tissue from CD and NIBD controls. Colonic epithelial cells and immune cells were isolated from colonic tissues, and microRNA-31 (miR-31) expression was measured. miR-31 expression was measured in colonoid cultures generated from controls and patients with CD. We performed small RNA-sequencing of formalin-fixed paraffin-embedded colon and ileum biopsies from treatment-naive pediatric patients with CD and controls and collected data on disease features and outcomes. RESULTS: Small RNA-sequencing and microRNA profiling in the colon revealed 2 distinct molecular subtypes, each with different clinical associations. Notably, we found that miR-31 expression was a driver of these 2 subtypes and, further, that miR-31 expression was particularly pronounced in epithelial cells. Colonoids revealed that miR-31 expression differences are preserved in this ex vivo system. In adult patients, low colonic miR-31 expression levels at the time of surgery were associated with worse disease outcome as measured by need for an end ileostomy and recurrence of disease in the neoterminal ileum. In pediatric patients, lower miR-31 expression at the time of diagnosis was associated with future development of fibrostenotic ileal CD requiring surgeryCONCLUSIONS. These findings represent an important step forward in designing more effective clinical trials and developing personalized CD therapies.
