Abstract
The principal limitations of the terms NAFLD and NASH are the reliance on exclusionary confounder terms and the use of potentially stigmatising language. This study set out to determine if content experts and patient advocates were in favor of a change in nomenclature and/or definition. A modified Delphi process was led by three large pan-national liver associations. The consensus was defined a priori as a supermajority (67%) vote. An independent committee of experts external to the nomenclature process made the final recommendation on the acronym and its diagnostic criteria. A total of 236 panelists from 56 countries participated in 4 online surveys and 2 hybrid meetings. Response rates across the 4 survey rounds were 87%, 83%, 83%, and 78%, respectively. Seventy-four percent of respondents felt that the current nomenclature was sufficiently flawed to consider a name change. The terms "nonalcoholic" and "fatty" were felt to be stigmatising by 61% and 66% of respondents, respectively. Steatotic liver disease was chosen as an overarching term to encompass the various aetiologies of steatosis. The term steatohepatitis was felt to be an important pathophysiological concept that should be retained. The name chosen to replace NAFLD was metabolic dysfunction-associated steatotic liver disease. There was consensus to change the definition to include the presence of at least 1 of 5 cardiometabolic risk factors. Those with no metabolic parameters and no known cause were deemed to have cryptogenic steatotic liver disease. A new category, outside pure metabolic dysfunction-associated steatotic liver disease, termed metabolic and alcohol related/associated liver disease (MetALD), was selected to describe those with metabolic dysfunction-associated steatotic liver disease, who consume greater amounts of alcohol per week (140-350 g/wk and 210-420 g/wk for females and males, respectively). The new nomenclature and diagnostic criteria are widely supported and nonstigmatising, and can improve awareness and patient identification.

Abstract
BACKGROUND The global prevalence of nonalcoholic steatohepatitis (NASH) is rising. Despite this, NASH is underdiagnosed and does not yet have approved pharmacological treatments. We sought to understand the path to diagnosis, patient interactions with healthcare professionals, treatment regimens, and disease management for patients with NASH. METHODS Cross-sectional online surveys of patients with a self-reported diagnosis of NASH and healthcare professionals treating patients with NASH were conducted from 10th November 2020, to 1st January 2021. This manuscript focuses on responses from 152 patients with NASH and 101 primary care physicians (PCPs). RESULTS Patients (n = 152, mean age = 40, SD = 11) and healthcare professionals (n = 226) were located throughout the US. In the most common patient journey, 72% of patients had initial discussions about symptoms with a PCP but only 30% report receiving their NASH diagnosis from a PCP. Almost half of PCPs (47%) were not aware of any clinical practice guidelines for diagnosis and management of NASH. For ongoing management of NASH, PCPs most frequently prescribed lifestyle changes such as exercise (89%), lifestyle changes focused on diet (79%), and/or metformin (57%). Other healthcare professionals rarely referred patients to PCPs for treatment, but when they did, the primary reasons were patients struggling with lifestyle modifications (58%), needing to lose weight (46%), and needing treatment of comorbidities (42%). CONCLUSIONS PCPs may benefit from greater awareness of NASH and guidelines for its diagnosis and treatment. Given the absence of pharmacological treatments approved for NASH, PCPs can offer support in obesity management, comorbidity management, and risk stratification for liver disease progression.

Abstract
Diagnosing and managing metabolic dysfunction-associated steatotic liver disease (MASLD) remains a major challenge in primary care due to lack of agreement on diagnostic tools, difficulty in identifying symptoms and determining their cause, absence of approved pharmacological treatments, and limited awareness of the disease. However, prompt diagnosis and management are critical to preventing MASLD from progressing to more severe forms of liver disease. This highlights the need to raise awareness and improve understanding of MASLD among both patients and physicians. The patient perspective is invaluable to advancing our knowledge of this disease and how to manage it, as their perspectives have led to the growing recognition that patients experience subtle symptoms and that patient-reported outcomes should be incorporated into drug development. This review and expert opinion examine MASLD and metabolic dysfunction-associated steatohepatitis from the patient and physician perspective from pre-diagnosis to diagnosis and early care, through to progression to advanced liver damage. Specifically, the paper dives into the issues patients and physicians experience, and, in turn, what is required to improve diagnosis and management, including tips and tools to empower patients and physicians dealing with MASLD.

Abstract
Abstract
Background
Nonalcoholic steatohepatitis (NASH), the inflammatory subtype of nonalcoholic fatty liver disease, is underdiagnosed and expected to become the leading indication for liver transplant in the United States. We aimed to understand the medical journey of patients with NASH and role of hepatologists/gastroenterologists in diagnosing and treating patients with NASH.
Methods
A United States population-based cross-sectional online survey was completed by 226 healthcare professionals (HCPs) who treat patients with NASH and 152 patients with NASH; this study focuses on the patient and 75 hepatologist/gastroenterologist HCP respondents. Tests of differences (chi square, t-tests) between respondent types were performed using SPSS.
Results
Most patients reported receiving their diagnosis of NASH from a hepatologist (37%) or gastroenterologist (26%). Hepatologists/gastroenterologists were more likely than other HCPs to use FibroScan (transient elastography) to diagnose NASH and were more likely to distinguish between NASH with or without fibrosis. Hepatologists/gastroenterologists (68%) and patients (52%) agree that hepatologists/gastroenterologists are the primary coordinators of NASH care. The majority of hepatologists/gastroenterologists (85%) are aware of American Association for the Study of Liver Diseases (AASLD) clinical practice guidance, and 86% of those aware consider them when diagnosing patients with NASH. Hepatologists/gastroenterologists most frequently recommended exercise (86%), diet (70%), and supplements (58%) for ongoing management of NASH. Pharmaceutical medications for comorbidities were prescribed by a minority of hepatologists/gastroenterologists for their patients with NASH. Hepatologists/gastroenterologists cite difficulty (67%) or unwillingness (64%) to adhere to lifestyle changes as primary reasons patients with NASH discontinue NASH treatment.
Conclusions
Hepatologists/gastroenterologists are considered the coordinators of NASH care. While recognizing that patient adherence to lifestyle changes is the basis for successful treatment, important barriers limit successful implementation.

Abstract
PURPOSE This Provisional Clinical Opinion update presents a clinically pragmatic approach to hepatitis B virus (HBV) screening and management. PROVISIONAL CLINICAL OPINION All patients anticipating systemic anticancer therapy should be tested for HBV by 3 tests-hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc) total immunoglobulin (Ig) or IgG, and antibody to hepatitis B surface antigen-but anticancer therapy should not be delayed. Findings of chronic HBV (HBsAg-positive) or past HBV (HBsAg-negative and anti-HBc-positive) infection require HBV reactivation risk assessment.Patients with chronic HBV receiving any systemic anticancer therapy should receive antiviral prophylactic therapy through and for minimum 12 months following anticancer therapy. Hormonal therapy alone should not pose a substantial risk of HBV reactivation in patients with chronic HBV receiving hormonal therapy alone; these patients may follow noncancer HBV monitoring and treatment guidance. Coordination of care with a clinician experienced in HBV management is recommended for patients with chronic HBV to determine HBV monitoring and long-term antiviral therapy after completion of anticancer therapy.Patients with past HBV infection undergoing anticancer therapies associated with a high risk of HBV reactivation, such as anti-CD20 monoclonal antibodies or stem-cell transplantation, should receive antiviral prophylaxis during and for minimum 12 months after anticancer therapy completion, with individualized management thereafter. Careful monitoring may be an alternative if patients and providers can adhere to frequent, consistent follow-up so antiviral therapy may begin at the earliest sign of reactivation. Patients with past HBV undergoing other systemic anticancer therapies not clearly associated with a high risk of HBV reactivation should be monitored with HBsAg and alanine aminotransferase during cancer treatment; antiviral therapy should commence if HBV reactivation occurs.Additional information is available at www.asco.org/supportive-care-guidelines.

Abstract
PURPOSE This updated provisional clinical opinion presents a revised opinion based on American Society of Clinical Oncology panel consensus in the context of an evolving database. CONTEXT Despite the 2010 provisional clinical opinion recommendation, there is still evidence of suboptimal hepatitis B virus (HBV) screening among patients at high risk for HBV infection or HBV reactivation after chemotherapy. This updated provisional clinical opinion introduces a risk-adaptive strategy to identify and treat patients with HBV infection to reduce their risk of HBV reactivation. PROVISIONAL CLINICAL OPINION Medical providers should screen by testing patients for HBV infection before starting anti-CD20 therapy or hematopoietic cell transplantation. Providers should also screen patients with risk factors for HBV infection. Screening should include both hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc), because reactivation can occur in patients who are HBsAg positive/anti-HBc positive or HBsAg negative/anti-HBc positive. Either total anti-HBc or anti-HBc immunoglobulin G (not immunoglobulin M) test should be used. Clinicians should start antiviral therapy for HBsAg-positive/anti-HBc-positive patients before or contemporaneously with cancer therapy and monitor HBsAg-negative/anti-HBc-positive patients for reactivation with HBV DNA and ALT levels, promptly starting antivirals if reactivation occurs. Clinicians can initiate antivirals for HBsAg-negative/anti-HBc-positive patients anticipating cancer therapies associated with a high risk of reactivation, or they can monitor HBV DNA and ALT levels and initiate on-demand antivirals. For patients who neither have HBV risk factors nor anticipate cancer therapy associated with a high risk of reactivation, current evidence does not support HBV screening before initiation of cancer therapy. Two panel members provided a minority viewpoint, involving a strategy of universal HBsAg and selective anti-HBc testing.

Abstract
The contribution of the kinetics of exogeneous and endogenous lipoproteins in determining the level of triglyceride in fasting plasma was assessed in a group of 19 normolipidaemic and hypertriglyceridaemic subjects. From data derived during a 9-h infusion of [15N]-glycine, we have assessed very low density lipoprotein apolipoprotein B production, and from data analysed by kinetic modelling obtained following ingestion of retinol and triolein, we have assessed chylomicron and chylomicron remnant clearance in a group of 19 normolipidaemic and hypertriglyceridaemic subjects. A strong positive correlation was observed between the fasting plasma triglyceride level and the reciprocal of the apolipoprotein B fractional synthetic rate (r = 0.83, P less than 0.01). A positive correlation was also found with the rate of clearance of chylomicron remnants (Sf 20-400; r = 0.87, P less than 0.01) and of chylomicrons (Sf greater than 400; r = 0.69, P less than 0.01). No correlation was found between the fasting plasma triglyceride level and either of the plasma post-heparin lipolytic activities. Multivariate analysis revealed that 95% of the variance in triglyceride levels could be explained by the apolipoprotein B fractional synthetic rate and the chylomicron remnant clearance rate. The strong correlation between chylomicron remnant clearance, a measure of exogenous lipid metabolism, and fasting (hence, endogenous) plasma triglyceride levels suggests that remnants of chylomicrons and very low density lipoproteins share some common components of the removal process.

Abstract
We have assessed very low-density lipoprotein apolipoprotein B production, using [15N]glycine as an endogenous marker in a 9-hour primed constant infusion protocol, in four adult male subjects with familial combined hyperlipidaemia and in four normolipidaemic adult male controls. The mean very low-density lipoprotein apolipoprotein B absolute synthetic rate was significantly greater in the familial combined hyperlipidaemic subjects than in control subjects (26.31 +/- 8.37 vs 9.36 +/- 4.07 mg/kg per 24 h, p less than 0.05). These results confirm findings using exogenous radioisotope labelling techniques that very low-density lipoprotein apolipoprotein B production is significantly increased in most patients with familial combined hyperlipidaemia. A modified 9-hour protocol can be safely done repeatedly and in children and pregnant women.

Abstract
We describe a new stable isotope technique for the in vivo study of hepatic plasma protein synthesis in humans. The method involves the infusion of (13C)sodium bicarbonate for 1 h and the measurement of the isotopic enrichment of (13C)arginine in newly synthesized apolipoprotein B of very low density lipoproteins (VLDL-apoB) and low density lipoproteins (LDL-apoB) in blood samples taken over a 5-6 h period from the commencement of the infusion. Isotope ratio mass spectrometry was utilized to measure 13CO2 enrichment following hydrolysis of these proteins and conversion of the guanidinium carbon of arginine in the hydrolysate to carbon dioxide by sequential incubation with arginase and urease. The method is capable of measuring isotopic enrichment as low as 0.001 at.% excess (APE) with a precision of 1.2%. In both subjects studied, the (13C)arginine of VLDL-apoB reached enrichments of 0.2 APE and that of the arginine of LDL-apoB, 0.03 APE. Incorporation of labeled arginine into LDL-apoB was demonstrable at 60-90 min. The new technique is safe and is applicable to the study of the hepatic biosynthesis of a wide range of plasma proteins.

Abstract
This paper describes an unusual kindred with familial hypercholesterolemia in which one-third of the relatives with a mutant LDL receptor gene have normal plasma cholesterol concentrations. The proband, a 9-yr-old boy with a plasma cholesterol value greater than 500 mg/dl, is homozygous for a point mutation that changes Ser156 to Leu in the LDL receptor. This substitution in the fourth repeat of the ligand binding domain slows the transport of the protein to the cell surface. The defective receptor cannot bind LDL, which contains apo B-100, but it does bind beta-migrating VLDL, which contains apo E in addition to apo B-100. Although the mother is heterozygous for this mutation, her LDL-cholesterol concentration is consistently in the 28th percentile for the population. Through direct examination of genomic DNA, we identified the mutant gene in heterozygous form in 17 of the mother's relatives, five of whom had normal LDL-cholesterol values. The pedigree was consistent with dominant transmission of a single gene that ameliorates or suppresses the hypercholesterolemic effect of the LDL receptor mutation. Through linkage analysis, we excluded the possibility that this suppressor gene was an allele at the LDL receptor locus. We also excluded the genes for the two ligands for the LDL receptor, apo B-100 and apo E. The existence of this putative suppressor gene may explain the occasional observation of normal LDL-cholesterol concentrations in heterozygotes for LDL receptor mutations.

Abstract
Rat livers were perfused by the nonrecirculating technique with medium containing [15N]glycine and sodium benzoate. At various times, the isotopic enrichment of hepatic free glycine, hepatic glycyl-tRNA, and perfusate hippurate was measured by GLC-MS. After 60 min, these parameters had reached approximately maximal values. At 90 min, the perfusate hippurate had a 30% greater enrichment of 15N than the intracellular glycine or glycyl-tRNA. Hippurate enrichment was half that of the medium glycine. The rat livers secreted apolipoprotein B (B-100 plus B-48) at a rate of 22 micrograms/g per h. From the 15N enrichment and the secretion rate, an intrahepatic pool size of 86 micrograms/g of apoB was calculated. From the minimal intracellular transit time of 30 min, an apoB fractional synthetic rate (FSR) of 2 pools/h was indicated, whereas the FSR estimated from the 15N-enrichment was 0.26/h. A possible explanation for the discrepancy is that apoB may recycle within the hepatocyte. On the basis of the present experiments, when hippurate enrichment is used as a measure of the enrichment of intrahepatic glycine in in vivo studies with 15N-labeled glycine, a correction should be applied, under normal metabolic circumstances, of approximately 20-30%.

Abstract
The kinetics of chylomicron metabolism have been studied by measuring retinyl palmitate in chylomicrons and their remnants for 10-12 hr following oral administration of vitamin A and Lipomul in three groups of adult male subjects: A) normal plasma triglyceride levels (n = 7); B) endogenous hypertriglyceridemia (n = 12); C) apolipoprotein E (apoE) phenotype E2/2, with Type 3 hyperlipoproteinemia (n = 4) or normal plasma lipids (n = 1). A multicompartmental model was developed using SAAM 27 to characterize the appearance, intravascular metabolism, and clearance from the plasma of retinyl palmitate-labeled dietary lipoproteins. The half-times for retinyl palmitate clearance from the chylomicron remnant fraction (T1/2 REMNANT) were 14.1 +/- 9.7 min in Group A; they were prolonged in Group B (50.7 +/- 20.8 min) and were extremely prolonged for Type 3 subjects in Group C (611.9 +/- 419.9 min). One subject with the apoE 2/2 phenotype and normal plasma triglycerides had a T1/2 REMNANT of 66.8 min. T1/2 REMNANT was highly correlated with fasting plasma triglycerides in Group A and B (r = 0.77, slope = 0.15), and in Group C (r = 0.97, slope = 0.85). These results support the interpretation that delayed chylomicron remnant clearance in subjects with endogenous hypertriglyceridemia may be largely secondary to overproduction of VLDL particles, whose remnants compete with chylomicron remnants for removal by the liver via apoE receptor-mediated endocytosis. The subjects with apoE 2/2 have an additional defect in the removal of chylomicron remnants presumably due to the structural abnormality in their apoE.

Abstract
Stable isotope methodology has been adapted to the study of lipoprotein turnover in human subjects. Using endogenous [15N]glycine labeling and gas-liquid chromatographic-mass spectrometric analysis, synthesis of apolipoprotein B in very low density lipoprotein (VLDL) was measured directly in five normal and two hyperlipidemic subjects. An isotopic precursor steady state was achieved during the studies by utilizing a priming dose and constant infusion containing [15N]glycine. Measurement of the plateau in 15N enrichment in the urinary hippurate produced during each study was used to estimate the 15N enrichment of the hepatic glycine precursor pool. The range of values for the fractional synthetic rate of VLDL apoB in the normal subjects obtained by this method was 5.9 to 11.5 day-1, with a mean of 9.2 +/- 2.4 (SD). This value agrees with the results of previous investigations which have utilized other methods. The method was also tested in two hypertriglyceridemic subjects and gave fractional synthetic rates of VLDL apoB that were significantly lower than in normals (1.5 and 2.8 day-1). This stable isotope method allows calculation of the fractional synthetic rate of VLDL apoB by maintaining an isotopic steady state throughout the study. It makes possible repeated studies in the same individual since no risk of exposure to radioisotopes is involved.
