MASLD Pharmacotherapy With Tessa Janovsky
September 2025
Join Tessa Janovsky, PA-C from Arizona Liver for a practical update on MASLD pharmacotherapy—from whole-patient metabolic management to liver-directed treatment. This session reviews why care must target the entire metabolic syndrome (weight, type 2 diabetes, hypertension, dyslipidemia, cardiovascular risk), the impact of 7–10% weight loss (and why many patients need adjuncts), and how to choose between diet/physical activity, anti-obesity medications, and bariatric surgery for select cases. You’ll learn where GLP-1 receptor agonists fit (mechanism, expected weight and glycemic effects, GI side effects, peri-procedure anesthesia considerations, and use in compensated disease), when to use statins safely in fatty liver, and how to stage and monitor with FIB-4, FibroScan/elastography, and other non-invasive tests. Tessa also summarizes legacy data for vitamin E and pioglitazone (benefits and limitations) and highlights the first FDA-approved therapy for non-cirrhotic MASH with F2–F3 fibrosis, resmetirom—including mechanism (THR-β agonism), tolerability, drug–drug interaction checkpoints, and practical follow-up (restaging and lifestyle coaching). If you’re a GI/hepatology clinician or APP aiming to streamline risk reduction, staging, and evidence-based therapy for MASLD/MASH, this concise talk delivers clinic-ready guidance.

MASLD Pharmacotherapy With Jill Olmstead
September 2025
Join Jill Olmstead, DNP from Providence Health for a practical, clinician-focused overview of MASLD pharmacotherapy and new treatment horizons for hepatic steatosis. This session in the GHAPP MASLD & MASH Community Network covers the shift in nomenclature, why care must be multidisciplinary (obesity, type 2 diabetes, dyslipidemia, hypertension, cardiovascular risk), and how to stage disease with FIB-4, noninvasive tests, and FibroScan before initiating therapy. Jill reviews lifestyle and weight-loss strategies, GLP-1 receptor agonists—their mechanisms, common GI side effects, and peri-procedure considerations due to delayed gastric emptying—plus where vitamin E and pioglitazone do and don’t fit today. She also walks through practical use of resmetirom for non-cirrhotic MASH with F2–F3 fibrosis (labs to order, monitoring, drug–drug interactions, and setting expectations alongside diet and exercise). If you’re a GI/hepatology clinician, APP, or primary-care partner looking to streamline risk reduction, staging, and evidence-based therapy for MASLD/MASH, this talk delivers step-by-step guidance you can use in clinic today.

MASLD vs MetALD With Christina Hanson
September 2025
Discover the latest insights on MASLD and MetALD in this educational session from the GHAPP MASLD Community Network. Christina Hanson, FNP-C, walks through a real-world case study to highlight how common metabolic conditions like hypertension, hyperlipidemia, obesity, and PCOS intersect with alcohol use to drive liver disease progression. The session explores updated nomenclature replacing NAFLD/NASH, the role of FibroScan and elastography in staging fibrosis, and the importance of screening patients with metabolic risk factors for fatty liver. Learn how alcohol consumption contributes to liver injury, triglyceride elevation, and blood pressure changes, and how objective biomarkers such as PEth testing are transforming diagnosis beyond self-reporting. Christina also reviews lifestyle interventions, dietary strategies like the Mediterranean diet, and current treatment considerations for patients with advanced fibrosis (stage 3), including when to initiate HCC screening. Whether you are a hepatologist, GI specialist, or advanced practice provider, this session provides practical tools for evaluating and managing patients with MASLD, MetALD, and related liver health challenges.

MASLD Pharmacotherapy With Christina Hanson
September 2025
Learn about the latest advances in MASLD and MASH pharmacotherapy in this educational session from the GHAPP MASLD Community Network. Christina Hanson, NP, reviews the evolving landscape of treatment for metabolic dysfunction-associated steatotic liver disease (MASLD) and steatohepatitis (MASH), including the critical role of weight loss, cardiovascular risk reduction, and liver-directed therapies. The discussion covers current management strategies such as GLP-1 receptor agonists, bariatric interventions, statins, and lifestyle modification, while also exploring guideline-supported options like vitamin E and pioglitazone. Special attention is given to the first FDA-approved therapy for MASH, Resmetirom, including its mechanism, clinical trial results, safety considerations, and monitoring recommendations. Whether you are a hepatology specialist, primary care provider, endocrinologist, or advanced practice provider, this session highlights practical approaches to managing patients with MASLD and MASH and offers insights into emerging therapies that may shape future clinical practice.

MASLD Basics With Jill Olmstead
August 2025
Join Jill Olmstead, NP, a seasoned gastroenterology nurse practitioner from Providence St. Joseph Health, for an in-depth overview of MASLD (Metabolic Dysfunction-Associated Steatotic Liver Disease) and MASH (Metabolic Steatohepatitis) in this GHAPP MASLD Community Network presentation, proudly sponsored by Madrigal Pharmaceuticals. With over 20 years of clinical experience, Jill explains the evolving nomenclature from NAFLD/NASH to MASLD/MASH and how this impacts diagnostic criteria, patient communication, and multidisciplinary management. Learn how to identify steatotic liver disease, assess cardiometabolic risk factors, and use tools like FIB-4 and FibroScan to evaluate fibrosis and stratify risk. Jill walks through real-world case scenarios, highlighting when to order a liver biopsy, when to refer to hepatology, and how to apply AASLD guidelines in clinical practice. From evaluating elevated liver enzymes to addressing the global burden of MASLD and its progression to cirrhosis and HCC, this session is essential for providers navigating the complexities of modern liver disease management in both primary care and specialty settings.
