BACKGROUND: Liver biopsy is a gold standard method for hepatic steatosis assessment. However, liver biopsy is an invasive and painful procedure and can cause severe complications therefore it cannot be frequently used in case of follow-up of patients. Non-invasive assessment of steatosis and fibrosis is of growing relevance in non-alcoholic fatty liver disease (NAFLD). To evaluate hepatic steatosis, transient elastography with controlled attenuation parameter (CAP) measurement is an option now days...

BACKGROUND & AIMS: Treatment with the combination of ledipasvir and sofosbuvir for 12 weeks has been approved by the Food and Drug Administration for patients with genotype 1 hepatitis C virus (HCV) infection; some patients can be treated with an 8-week course. Guidelines recommend a 12-week treatment course for black patients, but studies have not compared the effectiveness of 8 vs 12 weeks in black patients who are otherwise eligible for an 8-week treatment regimen. METHODS: We conducted an observational study of Kaiser Permanente Northern California members with HCV genotype 1 infection who were eligible for 8 weeks of treatment with ledipasvir and sofosbuvir (treatment-naïve, no cirrhosis, no HIV infection, level of HCV RNA <6 million IU/mL) and were treated for 8 or 12 weeks from October 2014 through December 2016...

Two-dimensional shear wave elastography (2D-SWE) is a rapid, simple and novel noninvasive method that has been proposed for assessing hepatic fibrosis in patients with chronic liver diseases (CLDs) based on measurements of liver stiffness. 2D-SWE can be performed easily at the bedside or in an outpatient clinic and yields immediate results with good reproducibility. Furthermore, 2D-SWE was an efficient method for evaluating liver fibrosis in small to moderately sized clinical trials. However, the quality criteria for the staging of liver fibrosis are not yet well defined...

BACKGROUND: The current management paradigm for children with single ventricle heart disease involves a series of palliative surgeries, culminating in the Fontan operation. This physiology results in a high central venous pressure, and in the setting of single ventricle heart disease, results in hepatic injury and fibrosis over time. Fontan-associated liver disease (FALD) is universally present in this cohort, and the current gold standard for diagnosis remains biopsy. Noninvasive assessments of liver fibrosis, such as ultrasound with elastography or acoustic radiation force impulse (ARFI), has been utilized in this cohort...

Primary biliary cholangitis (PBC) is known to be a major risk factor for osteoporosis reflected by a reduction of bone mineral density (BMD). However, both the extent of the macro- and microstructural alterations of bone as well as the causative factors are unknown. We have retrospectively analyzed a total of 96 patients with PBC and 53 healthy controls matched for age, sex and body mass index. In addition to dual-energy X-ray absorptiometry (DXA) measurements at the lumbar spine and hip, high-resolution peripheral quantitative computed tomography (HR-pQCT) was used to assess the geometric, volumetric and microstructural changes of bone at the distal radius and tibia...
