Hepatol Commun

Department of Medicine, Division of Gastroenterology and Hepatology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Article Synopsis
  • Patients with cirrhosis have a higher risk of dying after surgery, often due to complications from portal hypertension, and some believe preoperative TIPS (transjugular intrahepatic portosystemic shunt) placement might help reduce this risk.
  • A study analyzed data from Veterans Health Administration patients who had major surgery between 2008-2022, comparing outcomes between those who had TIPS placed within 6 months of surgery and those who did not.
  • Results showed that TIPS placement was linked to a significantly higher risk of postoperative mortality and indicated poorer liver function right before surgery, suggesting that TIPS may not be beneficial for all patients with cirrhosis undergoing surgery.

Survival Benefit From Corticosteroids in Severe Alcohol-associated Hepatitis Attributed to Clinical and Treatment Differences in a Large Multicenter Cohort.

Clin Transl Gastroenterol

January 2025

Department of Medicine, Division of Gastroenterology and Hepatology, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Introduction: Corticosteroids are recommended by multiple society guidelines for the treatment of severe alcohol-associated hepatitis (AH). However, their use remains controversial due to inconsistent studies regarding their survival benefit.

Methods: This was a retrospective cohort study of first-time hospitalizations for severe AH (Maddrey discriminant function ≥ 32) admitted to the Veterans Health Administration between January 3, 2005, and December 5, 2020, (i) evaluating the effect of corticosteroid therapy on all-cause survival, (ii) characterizing the clinical and psychosocial factors associated with corticosteroid use, and (iii) determining the effect of duration of corticosteroid therapy on all-cause survival among treatment-responsive patients (Lille score < 0.

Article Synopsis
  • The study aimed to find protein signatures in blood that could help identify individuals at high risk for inflammatory bowel disease (IBD), specifically Crohn's disease (CD) and ulcerative colitis.
  • Researchers analyzed blood samples from a large population, utilizing machine-learning methods to identify and validate these protein signatures across multiple cohorts.
  • A specific combination of 29 proteins was effective in differentiating preclinical CD cases from controls, achieving a high accuracy, while the prediction for ulcerative colitis was less robust but still significant.

Department of Biostatistics, Epidemiology, and Informatics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania; Abramson Cancer Center, University of Pennsylvania, Philadelphia, Pennsylvania; Center for Clinical Epidemiology and Biostatistics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, Pennsylvania. Electronic address:

Clinical trials evaluating chimeric antigen receptor T-cell therapy (CAR T) commonly report time-to-event (TTE) endpoints. However, definitions are not necessarily comparable across studies and variability can lead to misinterpretation of results or inappropriate comparisons across products and studies. Amid the rapidly increasing number of published CAR T trials-many of which were used for regulatory approval-this study aims to summarize the variation in the use and reporting of TTE endpoints in CAR T trials.

Since lack of culture-specific foods in dietary assessment methods may bias reported dietary intake, we identified foods and dishes consumed by residents not born in Sweden and describe consequences for reported foods and nutrient intake using a culturally adapted dietary assessment method. Design consisted of cross-sectional data collection using (semi-)qualitative methods of dietary assessment (and national diet survey instrument ) with subsequent longitudinal data collection using quantitative methods for method comparison (December 2020-January 2023). Three community-based research groups were recruited that consisted of mothers born in Sweden, Syria/Iraq, and Somalia, with a median age of 34, 37, and 36 years, respectively.

Background: Short-course tuberculosis (TB) prevention regimens, including 12 weeks of isoniazid and rifapentine (3HP), are increasingly used in high-TB-burden countries. Despite established safety and tolerability in efficacy trials, 3HP-related adverse events (AEs) could differ in routine settings. Real-world data on AE type, frequency, and timing are crucial for health systems considering 3HP programmatic scale-up.

  • * Data from over 6,500 patients was analyzed, comparing those treated with SGLT2i to those who weren't, showing that SGLT2i users were more likely to maintain CKD stage 3 status over a 10-year period.
  • * Results indicated that patients taking SGLT2i had significantly lower transition probabilities to more severe CKD stages and death, suggesting SGLT2i may help delay kidney function decline in T2D patients.
