Serological Workup: A Step-by-Step Guide With Jill Olmstead
September 2025
Join Jill Olmstead, DNP from Providence Health in Southern California for a step-by-step guide on working up patients with elevated liver enzymes in this MASLD & MASH Community Network podcast. Jill reviews how to distinguish acute vs. chronic liver injury, interpret patterns of hepatocellular vs. cholestatic damage, and order the right serologic tests, including viral hepatitis panels, autoimmune markers (ANA, ASMA, AMA), Wilson’s disease, alpha-1 antitrypsin deficiency, iron studies, and celiac screening. She highlights common causes such as alcohol use and MASLD—now one of the leading causes of liver transplantation—and explains when to use abdominal ultrasound, MRCP, or ERCP to assess for gallstones, biliary obstruction, or sludge. Jill also emphasizes the role of noninvasive fibrosis assessment (FIB-4 score, FibroScan®, fibrosis panels) in staging and treatment planning. With practical insights on history taking, medication review, alcohol counseling, and referral thresholds, this episode provides APPs, GI providers, and hepatology clinicians with a clear framework to evaluate and manage patients with abnormal liver tests and protect long-term liver health.

Misconceptions About Liver Health With Jill Olmstead
September 2025
Join Jill Olmstead, DNP from Providence Health in Southern California for an eye-opening GHAPP MASLD Community Network Insight on the biggest misconceptions about liver health. In this session, Jill explains why fatty liver disease is not “normal” or harmless, but a serious metabolic disorder linked to obesity, prediabetes, diabetes, and high cholesterol. She highlights how fat in the liver causes cellular injury, leading to fibrosis and even cirrhosis if untreated. Jill also addresses the common myth that alcohol is safe in moderation—reminding patients that alcohol is a liver toxin and no amount is risk-free, despite outdated beliefs about red wine being heart-protective. This educational talk empowers providers and patients alike to recognize fatty liver disease early, manage risk factors, and adopt lifestyle changes that protect long-term liver health. Watch more from the MASLD & MASH Community Network to stay informed on advances in fatty liver disease education and care.

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 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.
