Webcast: Comparing F3 and F4 Fibrosis With Anna Marie Hefner & Renee Pozza
November 2025
Join Anna Marie Hefner, RN and Renee Pozza, FNP-BC from Southern California Liver & GI Centers for a practical, case-based deep dive into advanced MASLD/MASH—what F3 vs F4 (cirrhosis) really means for staging, treatment, and surveillance. Using a 55-year-old patient scenario, they walk through interpreting FIB-4, FibroScan® (kPa + CAP), ELF, and routine labs; when to add ultrasound + AFP for HCC surveillance, and when to scope for esophageal varices. You’ll hear how they structure follow-up (from biweekly check-ins early to every 3 months), tailor diet and exercise to real-world habits, incorporate GLP-1s for weight and metabolic control, and consider resmetirom for eligible F2–F3 patients (not F4). The session also covers when to escalate to colonoscopy for alternative bleeding sources, and how to alternate US with triphasic CT/MRI in high-risk patients. Perfect for GI/hepatology APPs looking for a clear, actionable framework to manage fibrosis progression and optimize outcomes.

Common Questions From Primary Care Providers About MASH
October 2025
In this educational video, Anna Marie Hefner, CPNP, a hepatology nurse practitioner at the Southern California Liver and GI Centers, shares valuable insights for primary care providers managing patients with fatty liver disease. Anna Marie explains how her community-based practice collaborates with local clinicians to streamline care for patients with MASLD (Metabolic Associated Steatotic Liver Disease) and MASH (Metabolic Associated Steatohepatitis). She outlines a clear approach for evaluating patients with elevated liver enzymes and fatty liver, including when to use non-invasive testing (NITs) such as FibroScan and how to interpret fibrosis stages (F0–F4) to guide next steps in management. Anna Marie emphasizes that patients with early-stage fibrosis (F0–F1) can often be managed in primary care with regular weight monitoring, labs, and annual imaging, while those with advanced fibrosis (F3–F4) require hepatology referral for specialized care and cirrhosis management. She also discusses how her team supports community physicians—offering FibroScan services, consultative guidance, and direct communication to ensure patients receive coordinated, evidence-based care. This session is a practical resource for APPs, hepatology teams, and primary care providers navigating fatty liver disease screening, risk stratification, and referral pathways.

NITs: A Practical Overview: Navigating the Basics
October 2025
In this informative session, Anna Marie Hefner, CPNP, a hepatology nurse practitioner at the Southern California Liver and GI Center, shares her 15+ years of experience managing patients with MASLD (Metabolic Associated Steatotic Liver Disease) and MASH (Metabolic Associated Steatohepatitis). She explains how her clinic has created a collaborative, patient-centered approach—hosting dedicated fatty liver clinics that foster education, peer support, and lifestyle discussion among patients. Anna Marie walks viewers through how to distinguish between simple steatosis and MASH, emphasizing that proper diagnosis drives appropriate management—from lifestyle counseling and diet modification for early stages to medication and specialist referral for advanced fibrosis or cirrhosis. She offers a detailed overview of non-invasive tests (NITs) such as FIB-4, ELF, FibroScan, and MRI elastography, outlining how each test is performed, how to interpret key cutoff values, and when to refer patients to hepatology. She also highlights the importance of evaluating comorbidities, including cardiovascular and metabolic risk factors, medication history, and family health background, as part of comprehensive liver assessment. Finally, she encourages providers to follow AASLD and EASL guidelines, utilize collaborative care across specialties, and engage with professional APP organizations like GHAPP to stay current on evolving best practices in fatty liver disease management.

Webcast: MASLD Basics With Anna Marie Hefner & Renee Pozza
October 2025
In this MASLD Community Network session, Anna Hefner, PhD, RN, CPNP, and Renee Pozza, PhD, RN, CNS, FNP-BC, of Southern California GI & Liver Centers break down the new nomenclature for steatotic liver disease (SLD) and what it means for clinical practice. They clarify how to distinguish MASLD from MASH, introduce the overlap category MetALD (metabolic-associated alcohol-related liver disease), and review differential causes of steatosis—from medications and viral hepatitis to genetic and cryptogenic etiologies. The faculty walk through practical primary-care screening with FIB-4, when to escalate with noninvasive tests (FibroScan® CAP/kPa, ELF), and the roles of ultrasound and MRI/MRE—plus when a liver biopsy is still warranted. You’ll learn staging cues (F0–F4), progression risk, who needs closer follow-up, and how to counsel patients on cardiometabolic risk reduction (weight loss, activity, triglyceride/HDL management, blood pressure, glucose). The talk also highlights pediatric considerations, terminology changes to reduce stigma, and tips for consistent waist-circumference measurement and alcohol-intake assessment—equipping PCPs, GI, and hepatology teams to identify fibrosis early and improve outcomes.
