Opportunistic interventions (OIs) are health events facilitated by healthcare providers through education that can motivate individuals to adopt risk-reducing behaviours. Our aim was to evaluate transient elastography (TE) as an OI in patients with AUD by assessing changes in validated psychometric scores (PS) of alcohol insight and readiness for change. In this prospective, proof-of-concept pilot study, patients with AUD without TE in the past year were enrolled from an inpatient addiction unit.

Background: Contemporary research in peripheral artery disease (PAD) remains limited due to lack of a national registry and low accuracy of diagnosis codes to identify patients with PAD.

Methods: Leveraging a novel natural language processing system that identifies PAD with high accuracy using ankle-brachial index and toe-brachial index values, we created a registry of 103 748 patients with new-onset PAD in the Veterans Health Administration. Study end points include mortality, cardiovascular events (hospitalization for acute myocardial infarction or stroke) and limb events (hospitalization for critical limb ischemia or major amputation) and were identified using Veterans Affairs and non-Veterans Affairs encounters.

Objectives: The impact of mild autonomous cortisol secretion (MACS) on cognition is incompletely characterized. We aimed to assess cognition in patients with MACS, identify factors associated with lower cognition, and determine the impact of adrenalectomy on cognition.

Methods: We conducted a cross-sectional study (4/2019 to 10/2022) and a longitudinal cohort study (10/2021 to 9/2023) of adults with MACS and referent subjects.

Article Synopsis
  • Research on peripheral artery disease (PAD) is hindered by the absence of a national registry and insufficient diagnostic coding in electronic health records.
  • A new natural language processing (NLP) system helped establish a registry of over 103,000 new PAD patients within the Veterans Health Administration, revealing high rates of comorbidities and significant clinical outcomes over a year.
  • The study found notable one-year mortality (9.4%) and incidences of cardiovascular (5.6 per 100 patient-years) and limb events (4.5 per 100 patient-years), highlighting the urgent need for better care strategies for this high-risk population.

Background: Severe alcohol-associated hepatitis (AH) that is nonresponsive to corticosteroids is associated with high mortality, particularly with concomitant acute-on-chronic liver failure (ACLF). Most patients will not be candidates for liver transplantation (LT) and their outcomes are largely unknown. Our aim was to determine the outcomes of these declined candidates and to derive practical prediction models for transplant-free survival applicable at the time of the waitlist decision.

Context: Mild autonomous cortisol secretion (MACS) is diagnosed based on postdexamethasone cortisol >1.8 µg/dL. Scarce evidence exists on steroid circadian secretion and steroid metabolome in MACS.

Background: Guidelines recommend kidney transplant alone (KTA) in compensated cirrhosis based on a few small studies, but this is not widely performed despite its potential benefit to patients and the organ supply. Our aim was to determine the outcomes of KTA in patients with compensated cirrhosis.

Study Design: From 1/2012 to 12/2021, outcomes in KTA recipients with compensated cirrhosis were retrospectively compared to patients with chronic liver disease (CLD) but no cirrhosis.

Article Synopsis
  • Over the past 20 years, significant research has focused on understanding the causes and effects of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), but there are still no approved treatments available.
  • Key factors contributing to the disease include excess fatty acids in the liver and the liver’s own fat production, along with genetics and other health conditions that affect how the disease progresses.
  • Despite early failures in drug trials, there is hope for new treatments, as phase 2 and 3 trials are currently underway, with two drugs (obeticholic acid and resmetirom) being considered for fast-track approval by the FDA this year.

Article Synopsis
  • The study aimed to determine the prevalence of frailty in patients with different adrenal disorders and assess its association with physical function measures using the Frailty Index (FI).
  • It involved 520 patients with adrenal issues and 89 referent subjects who completed a questionnaire measuring various health variables, with frailty defined as an FI score of 0.25 or higher.
  • Results showed a significantly higher prevalence of frailty in adrenal disorder patients, particularly those with Cushing syndrome, and the FI correlated with various physical function tests, indicating the need for future studies on management strategies for frailty.

Objective: Glucocorticoid withdrawal syndrome (GWS) is a scarcely studied phenomenon that complicates the recovery following surgical remission of hypercortisolism. We aimed to characterize the presence and trajectory of glucocorticoid withdrawal symptoms in the postoperative period and to determine presurgical predictors of GWS severity.

Design: Longitudinal observational study.

Objective: Prospective data on determinants of muscle strength impairment and quality of life in patients with various subtypes and severity of endogenous hypercortisolism are lacking.

Design: Single-center cross-sectional study, 2019 to 2022.

Methods: Patients with Cushing syndrome (CS) and mild autonomous cortisol secretion (MACS) were assessed with clinical and biochemical severity scores, muscle function (nondominant hand grip strength and sit-to-stand test), and quality of life (Short Form-36 [SF36] and CushingQoL).

Hepatitis D virus (HDV) infection is highly prevalent in patients with chronic hepatitis B (CHB). AASLD guidelines recommend a risk-based screening approach. Our aim was to ascertain if the risk-based approach leads to appropriate HDV screening, identify targets to improve screening rates, and study HDV clinical burden.
