Background Aims: Cirrhosis prevalence is increasing, yet costs associated with its chronic, complex care are poorly understood. The aim was to characterize the costs of care for patients with cirrhosis and compare them to other chronic diseases such as heart failure (HF) and chronic obstructive pulmonary disease (COPD), for which the public health burden is better recognized.

Approach: Patients enrolled in Medicare Advantage plans from a large national insurer between 2011-2020 with cirrhosis, HF, and COPD were identified by ICD-9/-10 codes.

Introduction: Kidney transplantation (KT) in older age is increasingly common as more elderly patients live with end-stage renal disease. Immunosuppression (IS) after KT confers additional risk in aging patients with weakened immune systems. We hypothesized that 1-year mortality among KT recipients aged 70 y and older would be higher in those receiving induction IS with alemtuzumab lymphocyte depletion versus basiliximab interleukin-2 inhibition.

Background & Aims: Cirrhosis-related inpatient hospitalizations have increased dramatically over the past decade. We used a longitudinal dataset capturing a large metropolitan area in the United States from 2011 to 2021 to evaluate contemporary hospitalization rates and risk factors among frail patients with cirrhosis.

Methods: We conducted a retrospective, longitudinal cohort study using the Chicago Area Patient-Centered Outcomes Research Network (CAPriCORN) database, an electronic health record repository that aggregates de-duplicated data across 7 health care systems in the Chicago metropolitan area, from 2011 to 2021.

Article Synopsis
  • Organ transplant recipients on immunosuppressants have a weakened ability to respond to infections, including SARS-CoV-2, but their antibody responses may still be effective.
  • A new mass spectrometry technique called Ig-MS was used to compare immune responses to COVID-19 between transplant recipients and immunocompetent controls at a single point and over a month after diagnosis.
  • The study found no significant differences in antibody characteristics like titer, clonality, or glycan composition between the two groups, suggesting that the immune response evolution in transplant recipients resembles that of immunocompetent individuals.

Advancements in anaerobic membrane bioreactor (AnMBR) technology have opened up exciting possibilities for sustaining precise water quality control in wastewater treatment and reuse. This approach not only presents an opportunity for energy generation and recovery but also produces an effluent that can serve as a valuable nutrient source for crop cultivation in hydroponic controlled environment agriculture (CEA). In this perspective article, we undertake a comparative analysis of two approaches to municipal wastewater utilization in agriculture.

Article Synopsis
  • Frailty and sarcopenia increase the risk of hospitalization and mortality in patients with end-stage liver disease, making it crucial to identify frail individuals during liver transplant evaluations.
  • In a study of 426 liver transplant recipients, 31% were sarcopenic and 25% were considered frail based on the Liver Frailty Index (LFI), with those groups showing longer post-transplant hospital stays.
  • While neither frailty nor sarcopenia significantly affected 1-year survival rates, the LFI score was linked to increased mortality, suggesting that physical frailty assessment is a better predictor of outcomes than muscle mass alone.

Introduction: Hepatic encephalopathy (HE) is a frequent complication of cirrhosis, leading to preventable hospitalizations and increased mortality. Despite the availability of validated neuro-psychometric tests to diagnose HE, only 10% of clinicians regularly screen for HE due to lack of time, equipment, and trained personnel.

Materials And Methods: We studied the association between patient-reported cognitive function and the National Institutes of Health Toolbox Cognition Battery (a validated measure of HE) in patients with cirrhosis.

Introduction: One of the primary goals of the Liver Cirrhosis Network (LCN) is to develop a cohort study to better understand and predict the risk of hepatic decompensation and other clinical and patient-reported outcomes among patients with Child A cirrhosis.

Methods: The LCN consists of a Scientific Data Coordinating Center and 10 clinical centers whose investigators populate multiple committees. The LCN Definitions and Measurements Committee developed preliminary definitions of cirrhosis and its complications by literature review, expert opinion, and reviewing definition documents developed by other organizations.

Electronic health records (EHR) data provides the researcher and physician with the opportunity to improve risk prediction by employing newer, more sophisticated modeling techniques. Rather than treating the impact of predictor variables on health trajectories as static, we explore the use of time-dependent variables in dynamically modeling time-to-event data through the use of landmarking (LM) data sets. We compare several different dynamic models presented in the literature that utilize LM data sets as the basis of their approach.

Physical frailty is a critical determinant of mortality in patients with cirrhosis and can be objectively measured using the Liver Frailty Index (LFI), which is potentially modifiable. We aimed to identify LFI cut-points associated with waitlist mortality. Ambulatory adults with cirrhosis without HCC awaiting liver transplantation from 9 centers from 2012 to 2021 for ≥3 months with ≥2 pre-liver transplantation LFI assessments were included.

Article Synopsis
  • Liver cirrhosis, often called a "silent killer," is increasingly prevalent, posing a significant healthcare burden, necessitating accurate measurement of its prevalence.
  • A study analyzing national health insurance data from 2011 to 2018 found a two-fold increase in cirrhosis cases, reaching a prevalence of 0.71% by 2018, with notable rises seen particularly among patients with Medicare Advantage and in Southern states.
  • The primary causes of this surge were alcohol-related and non-alcoholic steatohepatitis (NASH) cirrhosis, highlighting the need for targeted public health interventions to address this growing issue.

Social determinants of health (SDOH) are important predictors of poor clinical outcomes in chronic diseases, but their associations among the general cirrhosis population and liver transplantation (LT) are limited. We conducted a retrospective, multiinstitutional analysis of adult (≥18-years-old) patients with cirrhosis in metropolitan Chicago to determine the associations of poor neighborhood-level SDOH on decompensation complications, mortality, and LT waitlisting. Area deprivation index and covariates extracted from the American Census Survey were aspects of SDOH that were investigated.

Article Synopsis
  • A study analyzed infection and rejection outcomes in liver and heart transplant patients based on their postoperative insulin resistance, measured by peak insulin drip rates.
  • In liver transplant patients (n = 207), those in the highest insulin drip quartile (Q4) experienced significantly fewer infections (42.3% vs. 60.0%) and borderline fewer rejection episodes (25.0% vs. 40.0%) compared to lower quartiles.
  • Similarly, heart transplant patients (n = 188) in Q4 had significantly fewer infections (19.1% vs. 53.9%). The study suggests that a stronger counter-regulatory response to insulin resistance might correlate with better infection response and overall health.
