MAFLD / MASH (Metаbоlic Dysfunctiоn–Assоciаted Fаtty Liver Disease / Steatohepatitis) 1. Background MAFLD: Hepatic steatosis in patients with metabolic dysfunction (obesity, diabetes, dyslipidemia, or insulin resistance). MASH: Inflammatory subtype with hepatocellular injury and fibrosis. Replaces NAFLD/NASH terminology; alcohol intake no longer used to exclude diagnosis. Pathophysiology: Insulin resistance → increased fatty acid influx → triglyceride accumulation → oxidative stress → inflammation and fibrosis. Epidemiology: Most common liver disease in the U.S.; associated with metabolic syndrome, obesity, and diabetes. 2. History Often asymptomatic or presents with fatigue or mild RUQ discomfort. Risk factors: Central obesity, type 2 diabetes, dyslipidemia, hypertension, PCOS. Medications that worsen steatosis: corticosteroids, methotrexate, tamoxifen, amiodarone. 3. Exam Findings Mild hepatomegaly early. Advanced disease: jaundice, ascites, spider angiomas, palmar erythema, gynecomastia, splenomegaly. 4. Diagnosis Labs Mild elevation of AST/ALT (usually AST Late (fibrosis): AST > ALT Normal bilirubin and ALP unless advanced. Screen for metabolic syndrome (A1c, fasting glucose, lipids). Imaging Ultrasound: Increased echogenicity (“bright liver”). FibroScan (elastography): Measures fibrosis noninvasively. CT/MRI: Detects fat but not inflammation. Biopsy (if needed): Steatosis with ballooning degeneration, Mallory-Denk bodies, lobular inflammation, and pericellular fibrosis (MASH pattern). Diagnostic Criteria (2023): Evidence of hepatic steatosis plus one of: Overweight/obesity Type 2 diabetes ≥2 features of metabolic dysregulation (↑ waist circumference, dyslipidemia, insulin resistance, ↑ CRP, etc.) 5. Management Lifestyle (First-line) Weight loss ≥10% → improves steatohepatitis and fibrosis. Diet: Mediterranean or low-carbohydrate. Exercise: ≥150 minutes/week moderate activity. Avoid alcohol and hepatotoxic drugs. Pharmacologic Pioglitazone: For biopsy-proven MASH with T2DM. GLP-1 agonists (semaglutide): Reduce steatosis and promote weight loss. Vitamin E (800 IU/day): For non-diabetic MASH. No FDA-approved drug yet (as of 2025). Comorbidity Management Optimize glucose, lipids, and blood pressure (statins are safe). Monitoring / Surveillance Elastography every 1–2 years to assess fibrosis. HCC surveillance (ultrasound ± AFP every 6 months) if cirrhosis develops. Liver transplant for end-stage disease. Question A 49-year-old woman with obesity, hypertension, and type 2 diabetes presents for evaluation of mild fatigue. She denies alcohol use. Laboratory studies show: Test Result Reference Range ALT 68 U/L (7–56 U/L) AST 56 U/L (10–40 U/L) Alkaline phosphatase 98 U/L (44–147 U/L) Total bilirubin 0.8 mg/dL (0.2–1.2 mg/dL) Fasting glucose 152 mg/dL (70–99 mg/dL) Hemoglobin A1c 7.4% (
Wetlаnds stоre cаrbоn in plаnt biоmass and soils, but they can also release carbon dioxide and methane into the atmosphere. While not a comprehensive overview of the carbon cycle in this wetland, a measurement of soil carbon over time can how soil carbon stores change over time, relating to the wetland being a sink or a source. Imagine you are an environmental scientist studying a wetland near your campus. You and your classmates want to investigate: “Is the soil of this wetland acting as a carbon sink or a carbon source?" Which of the following choices could be a suitable hypothesis for this investigation?
