ABSTRACT
BACKGROUND: Metabolic dysfunction-associated fatty liver disease (MAFLD) is a rapidly growing global health problem. Despite its growing incidence and potential for significant repercussions, MAFLD is still widely misunderstood and underdiagnosed. AIM: The purpose of this study was to investigate MAFLD-related knowledge, attitudes, and risk profiles among university students aged 17 to 26. METHODS: A cross-sectional study with 406 university students in Lebanon, equally distributed among males and females, was conducted using a questionnaire that includes demographics, medical information, dietary habits, physical activity, and MAFLD-related knowledge and attitudes. RESULTS: The findings demonstrated a significant lack of knowledge regarding MAFLD, with more than half of participants (54.7%) having no prior knowledge of the illness. Students exhibited unhealthy lifestyle behaviors such as smoking (68%), insufficient physical exercise (44.1%), and poor food habits (52.5%). Having a family history of heart disease, personal history of diabetes mellitus, a balanced diet and prior knowledge of the disease were associated with a higher knowledge score (p<0.05). A higher attitude score existed among those who have a personal or family history of chronic diseases and those who have a prior negative impression about the disease, prior knowledge of the disease, and those who are physically active (p<0.05). CONCLUSION: Despite knowledge gaps, university students in Lebanon have, in general, an appropriate and positive attitude towards MAFLD. We recommend the introduction of focused educational interventions to address the necessity of lifestyle changes among university students and the community as a whole. Developing comprehensive MAFLD prevention methods requires future studies in different age groups and demographics.

In this editorial we comment on the article titled "Establishment and validation of an adherence prediction system for lifestyle interventions in non-alcoholic fatty liver disease" by Zeng et al published in a recent issue of the World Journal of Gastroenterology. Non-alcoholic fatty liver disease (NAFLD) represents one of the current challenges in hepatology and public health, due to its continuous growing prevalence and the rising incidence of NAFLD-related fibrosis, non-alcoholic steatohepatitis and cirrhosis. The only effective therapeutic strategy for this disease is represented by encouraging patients to improve their lifestyle through the modification of dietary intake and increased physical exercise, but the effective application of such modifications is often limited by various factors such as lack of information, psychological barriers or poor social support. While poor adherence to a healthy lifestyle can be decisive in determining the clinical outcome, in daily practice there is a lack of quantitative instruments aimed at identifying patients with the lowest adherence to lifestyle changes and higher risk of disease progression in the course of follow-up. In this article, Zeng et al propose a quantitative scale to assess the grade of adherence of patients with NAFLD to healthy lifestyle intervention, called the Exercise and Diet Adherence Scale (EDAS). This scale, consisting of 33 items divided into 6 dimensions which relates to six subjective aspects in the self-management of NAFLD, has shown a good correlation with the identification of the sub-cohort of patients with the highest reduction in caloric intake, increase in physical exercise, probability of a reduction in liver stiffness measurement and alanine aminotransferase levels. The correlation among clinical outcomes and specific dimensions of this scale also highlights the pivotal role of a good and confidential doctor-patient relationship and of an effective communication. There is an urgent need for practical and effective instruments to assess the grade of self-management of NAFLD patients, together with the development of multidisciplinary teams with the aim of applying structured behavioral interventions.

BACKGROUND: This study is designed to explore the correlation between multiple healthy lifestyles within the framework of "lifestyle medicine", and the mortality risk of nonalcoholic fatty liver disease (NAFLD). METHODS: The National Health and Nutrition Examination Survey (NHANES) database was employed. The analysis consisted of 5542 participants with baseline NAFLD and 5542 matched non-NAFLD participants from the database. Lifestyle information, including five low risk factors advocated by lifestyle medicine (healthy diet, vigorous physical activity, healthy sleep duration, avoiding smoking, and maintaining a non-depressed psychological status), was collected through a baseline questionnaire. Cox proportional hazards regression models and Kaplan-Meier survival curve were used to evaluate risk of mortality. In addition, subgroups were analyzed according to gender, age, body mass index and waist circumference. RESULTS: In total, 502 deaths (n = 181 deaths from cardiovascular disease (CVD)) were recorded among NAFLD participants after the median follow up duration of 6.5 years. In the multivariate-adjusted model, compared to participants with an unfavorable lifestyle (scoring 0-1), NAFLD participants with a favorable lifestyle (scoring 4-5) experienced a 56% reduction in all-cause mortality and a 66% reduction in CVD mortality. Maintaining an undepressed psychological state and adhering to vigorous exercise significantly reduced CVD mortality risk in NAFLD participants (HR, 0.64 [95% CI, 0.43-0.95]; HR, 0.54 [95% CI, 0.33-0.88]) while maintaining healthy sleep reduced premature mortality due to CVD by 31%. CONCLUSIONS: Healthy lifestyle, characterized by maintaining an undepressed mental state and healthy sleep, significantly mitigates the risk of all-cause, CVD, and premature mortality risk among NAFLD patients, with a particularly pronounced effect observed in female and obese subpopulations.

BACKGROUND: It is unclear what biopsychosocial factors influence the impact of NAFLD on health-related quality of life (HRQoL), and if these factors are equally important predictors between different nationalities. METHODS: HRQoL (CLDQ) was measured in both Southern European (Spain, n = 513) and Northern European (United Kingdom -UK-, n = 224) cohorts of patients with NAFLD in this cross-sectional study. For each cohort, participant data were recorded on histological grade of steatohepatitis, stage of fibrosis and biopsychosocial variables. Regression analysis was used to explore which of these variables predicted HRQoL. Moderated mediation models were conducted using SPSS PROCESS v3.5 macro. RESULTS: Participants with severe fibrosis reported more fatigue, systemic symptoms and worry, and lower HRQoL than those with none/mild fibrosis, regardless of place of origin. In addition, body mass index (BMI) and gender were found to be significant predictors of HRQoL in both Spanish and UK participants. Female gender was associated with worse emotional function, higher BMI and more fatigue, which predicted lower participants' HRQoL. UK participants showed more systemic symptoms and worry than Spanish participants, regardless of liver severity. The negative effects of gender on HRQoL through emotional function, BMI and fatigue were reported to a greater degree in UK than in Spanish participants. CONCLUSIONS: UK participants showed a greater impairment in HRQoL as compared to Spanish participants. Higher fibrosis stage predicted lower HRQoL, mainly in the Spanish cohort. Factors such as female gender or higher BMI contributed to the impact on HRQoL in both cohorts of patients and should be considered in future multinational intervention studies in NAFLD.

Background: Non-alcoholic fatty liver disease (NAFLD) is a common chronic liver disease, affecting 25-30% of the general population globally. The condition is even more prevalent in individuals with obesity and is frequently linked to the metabolic syndrome. Given the known associations between the metabolic syndrome and common mental health issues, it is likely that such a relationship also exists between NAFLD and mental health problems. However, studies in this field remain limited. Accordingly, the aim of this systematic review and meta-analysis was to explore the prevalence of one or more common mental health conditions (i.e., depression, anxiety, and/or stress) in adults with NAFLD. Methods: PubMed, EBSCOhost, ProQuest, Ovid, Web of Science, and Scopus were searched in order to identify studies reporting the prevalence of depression, anxiety, and/or stress among adults with NAFLD. A random-effects model was utilized to calculate the pooled prevalence and confidence intervals for depression, anxiety and stress. Results: In total, 31 studies were eligible for inclusion, involving 2,126,593 adults with NAFLD. Meta-analyses yielded a pooled prevalence of 26.3% (95% CI: 19.2 to 34) for depression, 37.2% (95% CI: 21.6 to 54.3%) for anxiety, and 51.4% (95% CI: 5.5 to 95.8%) for stress among adults with NAFLD. Conclusion: The present findings suggest a high prevalence of mental health morbidity among adults with NAFLD. Given the related public health impact, this finding should prompt further research to investigate such associations and elucidate potential associations between NAFLD and mental health morbidity, exploring potential shared underlying pathophysiologic mechanisms.

BACKGROUND AND AIMS: The itemization difference of patient-reported outcome (PRO) in hepatitis patients with different etiologies remains elusive in Asia. We aimed to assess the characteristics and the difference of health-related quality of life (HRQoL) in chronic hepatitis B (CHB), chronic hepatitis C (CHC), and non-alcoholic fatty liver disease (NAFLD) patients. METHODS: We conducted the study in an outpatient setting. The 36-Item Short Form Health Survey (SF-36) was completed by the patients upon the initial diagnosis and recruitment for a long-term follow-up purpose. The PRO results were also assessed by disease severity. RESULTS: There were 244 patients (198 males) of CHB, 54 patients (29 males) of CHC, and 129 patients (85 males) of NAFLD, respectively. CHC patient had the mean score of 67.1 ± 23.3 in physical component summary (PCS) of the SF-36 health survey, which was significantly lower than CHB patients (76.4 ± 19.5), and NAFLD patients (77.5 ± 13.7), respectively (p = 0.001). The significantly lower performance of PCS in CHC patients was mainly attributed to the lower performance in physical functioning and bodily pain components. Higher fibrosis 4 index scores were significantly associated with lower PCS scores in all patient groups. There was no significant difference of mean mental component summary (MCS) between groups. However, NAFLD patients had significantly lower mental health scores than other groups (p = 0.02). CONCLUSIONS: The significant difference of HRQoL exists in hepatitis patients with different etiologies. Disease severity leads to a lower PCS performance.

BACKGROUND: Non-alcoholic fatty liver disease is a liver condition that is increasing worldwide and expected to become the number one cause of cirrhosis and hepatocellular carcinoma in the next 5 years. Currently there are no successful or approved pharmacological treatments. Weight loss is the first-line therapy as a 7 to 10% reduction improves steatosis, inflammation, hepatocyte ballooning, and fibrosis. To achieve this, lifestyle interventions including daily exercise and diet must be encouraged. We aimed to assess the effects of diet, exercise, or a combination of both compared to conventional treatment in patients with non-alcoholic fatty liver disease. METHODS AND FINDING: A literature search was performed in CENTRAL, EMBASE, and PubMed. Randomized controlled trials comparing lifestyle changes with conventional treatment were included, without date restriction. Two authors searched studies according to eligibility criteria, extracted data, and assessed study quality. Subgroup analysis was made by type of intervention, duration of intervention and supervision. We calculated mean differences between the intervention and the control group with their corresponding 95% confidence intervals. Quality of the evidence was assessed using the Cochrane Risk of bias tool. This study is registered in PROSPERO, number CRD42020184241, and checked with the PRISMA checklist. 30 RCTs met the inclusion criteria. Compared to conventional treatment, combined exercise with diet seems to elicit greater reductions in ALT (MD: -13.27 CI 95% -21.39, -5.16), AST (MD: -7.02 CI 95% -11.26, -2.78) and HOMA-IR (MD: -2.07 CI 95% -2.61, -1.46) than diet (ALT MD: -4.48 CI 95% -1.01, -0.21; HOMA-IR MD: -0.61 CI 95% -1.01, -0.21) and exercise (ALT and AST non-significant; HOMA-IR MD = -0.46 CI 95% -0.8, -0.12) alone. Additionally, exercise improved quality of life, cardiorespiratory fitness, and weight (MD: -2.64 CI 95% -5.18, -0.09). CONCLUSION: Lifestyle changes are effective in the treatment of NAFLD. Diet and exercise combined are superior to these interventions alone in improving liver enzymes and HOMA-IR.

BACKGROUND & AIMS: There are uncertainties regarding the burden of liver disease in patients with type 2 diabetes (T2D). Thus, we aimed to quantify the burden of liver disease, identify risk factors, and estimate attributable risks in patients with T2D. METHODS: We measured adjusted hazard ratios of liver disease progression to hepatocellular carcinoma and/or decompensated cirrhosis in a 2010-2020 retrospective, bicentric, longitudinal, cohort of 52,066 hospitalized patients with T2D. RESULTS: Mean age was 64±14 years and 58% were men. Alcohol use disorders accounted for 57% of liver-related complications and were associated with all liver-related risk factors. Non-metabolic liver-related risk factors accounted for 37% of the liver burden. T2D control was not associated with liver disease progression. The incidence (95% CI) of liver-related complications and of competing mortality were 3.9 (3.5-4.3) and 27.8 (26.7-28.9) per 1,000 person-years at risk, respectively. The cumulative incidence of liver disease progression exceeded the cumulative incidence of competing mortality only in the presence of well-identified risk factors of liver disease progression, including alcohol use. The incidence of hepatocellular carcinoma was 0.3 (95% CI 0.1-0.5) per 1,000 person-years in patients with obesity and it increased with age. The adjusted hazard ratios of liver disease progression were 55.7 (40.5-76.6), 3.5 (2.3-5.2), 8.9 (6.9-11.5), and 1.5 (1.1-2.1), for alcohol-related liver disease, alcohol use disorders without alcohol-related liver disease, non-metabolic liver-related risk factors, and obesity, respectively. The attributable fractions of alcohol use disorders, non-metabolic liver-related risk factors, and obesity to the liver burden were 55%, 14%, and 7%, respectively. CONCLUSIONS: In this analysis of data from 2 hospital-based cohorts of patients with T2D, alcohol use disorders, rather than obesity, contributed to most of the liver burden. These results suggest that patients with T2D should be advised to drink minimal amounts of alcohol. LAY SUMMARY: There is uncertainty on the burden of liver-related complications in patients with type 2 diabetes. We studied the risks of liver cancer and complications of liver disease in over 50,000 patients with type 2 diabetes. We found that alcohol was the main factor associated with complications of liver disease. This finding has major implications on the alcohol advice given to patients with type 2 diabetes.

Exercise is a foundational treatment for nonalcoholic fatty liver disease (NAFLD); however, the majority of patients are unable to initiate and maintain effective exercise habits and remain at increased risk for progressive liver disease. Barriers and limitations to exercise in patients with NAFLD have not been fully identified. We performed a single survey of 94 patients with biopsy-proven NAFLD to understand baseline physical activity and sedentary behavior, self-perceived fitness, limitations to exercise, potential solutions to increase physical activity behavior, and perception of exercise as a foundational treatment for NAFLD. For exploratory analyses, we evaluated differences in responses to the survey by grouping severity of hepatic fibrosis as follows: nonalcoholic fatty liver (NAFL); early stage (nonalcoholic steatohepatitis [NASH] F0, NASH F1, NASH F2); and late stage (NASH F3, NASH F4). Zero weekly total physical activity was reported by 29% of patients with NAFLD. Late-stage NASH had significantly lower vigorous (P = 0.024), walking (P = 0.029), total weekly activity (P = 0.043), and current fitness level (P = 0.022) compared to early stage NASH. Overall, 72% of patients with NAFLD reported limitations to exercise, with the greatest proportion citing lack of energy (62%), fatigue (61%), prior/current Injury (50%), and shortness of breath (49%). A preference for personal training to increase their physical activity was indicated by 66% of patients with NAFLD, and 63% preferred exercise over medication to treat NAFLD. Conclusion: The majority of patients with NAFLD have limitations to exercise but prefer exercise as a treatment option for NAFLD in the form of personal training. Patients with NAFLD may have unique physiologic limitations to exercise that worsen with fibrosis severity. Exercise interventions or services that are personalized and scalable may improve sustainability of exercise habits in the long term.

Population-based studies that estimate awareness of nonalcoholic fatty liver disease (NAFLD) in the United States are scant. We aimed to understand public awareness of NAFLD and its temporal trends. Our study included 11,700 adults (18+ years old) from five National Health and Nutrition Examination Surveys (2007-2016). NAFLD was determined by the improved Fatty Liver Index for the multiethnic U.S. population (US-FLI) in the absence of secondary causes of liver disease. Overall prevalence of NAFLD, hepatitis C virus, and hepatitis B virus were 36.6%, 1.02% and 0.35%, respectively. From 2007-2008 to 2015-2016, awareness of liver disease among adults with NAFLD improved from 4.4% to 6.3% (trend P = 0.026) but 4 to 10 times lower than awareness about viral hepatitis. In 2015-2016, among adults with NAFLD, awareness of liver disease was lower among young adults (aged 18-29 years) compared with those aged ≥ 30 years (0% vs. 6.9%) and lower among non-Hispanic Blacks compared with other races (0.7% vs. 6.6%) (all P < 0.001). In multivariable analysis, young adults (adjusted odds ratio [aOR] = 0.29; confidence interval [CI] 0.10-0.87) and non-Hispanic Blacks (aOR = 0.43; CI 0.20-0.96) were negatively associated with awareness of liver disease among adults with NAFLD, whereas diabetes (aOR = 2.22; CI 1.37-3.58), advanced fibrosis (aOR = 2.34; CI 1.17-4.68), and a higher number of health care visits (aOR = 1.33; CI 1.15-1.50) were positively associated with awareness of liver disease. Nearly 96% of adults with NAFLD in the United States were unaware they had liver disease, especially among young adults and non-Hispanic Blacks. Findings indicate efforts are needed to improve awareness of NAFLD.

This trial evaluated the effects of co-supplementing Camelina sativa oil (CSO) and a prebiotic as modulators of the gut microbiota on cardiometabolic risk factors and mental health in NAFLD patients. In all, 44 subjects with NAFLD were allocated to either an intervention (20 g d-1 CSO + resistant dextrin) or a placebo (20 g d-1 CSO + maltodextrin) group and received a calorie-restricted diet (-500 kcal d-1) for 12 weeks. Fasting plasma levels of gucose, insulin, hs-CRP, endotoxin, antioxidant enzyme activity, total antioxidant capacity (TAC), malondialdehyde (MDA), 8-iso-prostaglandin F2α, and uric acid were measured at the baseline and post-intervention. The depression, anxiety and stress scale (DASS) and the general health questionnaire (GHQ) were used to assess mental health. Co-supplementing CSO and resistant dextrin significantly decreased the level of insulin concentration (-0.84 µU ml-1, p = 0.011), HOMA-IR (-0.27, p = 0.021), hs-CRP (-1.25 pg ml-1, p = 0.023), endotoxin (-3.70 EU mL-1, p = 0.001), cortisol (-2.43, p = 0.033), GHQ (-5.03, p = 0.035), DASS (-9.01, p = 0.024), and MDA (-0.54 nmol mL-1, p = 0.021) and increased the levels of TAC (0.16 mmol L-1, p = 0.032) and superoxide dismutase (106.32 U g-1 Hb, p = 0.45) in the intervention group compared with the placebo group. No significant changes were observed in the levels of other biomarkers. Co-supplementing CSO and resistant dextrin in combination with a low-calorie diet may improve metabolic risk factors and mental health in NAFLD patients.

BACKGROUND: Health Related Quality of Life (HRQL) is a multi-dimensional construct that can comprehensively evaluate the patient's health status, including physical, emotional, mental and social well-being. In this study, we aimed to evaluate the impact of non-alcoholic fatty liver disease (NAFLD) on HRQL in a Chinese population. METHODS: In this national multicenter cross-sectional survey, patients with NAFLD were enrolled. Chronic Liver Disease Questionnaire (CLDQ)-NAFLD was used to qualify HRQL. Univariate and multivariate analysis were used to identify independent risk factors of HRQL. RESULTS: A total of 5181 patients with NAFLD from 90 centers were enrolled in this study (mean age, 43.8 ± 13.3 years; male, 65.8%). The overall CLDQ score was 5.66 ± 0.89. Multivariate logistic regression analysis showed that body mass index (BMI: HR, 1.642; 95% CI, 1.330-2.026), alanine transaminase (ALT: HR, 1.006; 95% CI, 1.001-1.011), triglyceride (HR, 1.184; 95% CI, 1.074-1.305), disease severity (HR, 3.203; 95% CI, 1.418-7.232) and cardiovascular disease (HR, 4.305; 95% CI, 2.074-8.939) were independent risk factors for overall CLDQ score. In the logistic analyses of individual domain, BMI and triglyceride were independent risk factors of all domains. ALT, disease severity, diabetes, depression and cardiovascular disease were influencing factors for the CLDQ score of several domains. CONCLUSIONS: This national multicenter cross-sectional survey in China indicated that the HRQL in patients with NAFLD was impaired. HRQL was found to be significantly associated with sociodemographic and clinical factors. Attention should be paid to the optimally managing care of patients with NAFLD to improve their HRQL.

BACKGROUND: alcohol may have additional neurotoxic ill-effects in patients with alcohol related cirrhosis apart from hepatic encephalopathy. We aimed to evaluate minimal hepatic encephalopathy (MHE) with Psychometric Hepatic Encephalopathy (PHES) score and Critical Flicker Frequency (CFF) in alcohol (ALD) and non-alcoholic steatohepatitis related (NASH) related cirrhosis. METHODS: 398 patients were screened between March 2016 and December 2018; of which 71 patients were included in ALD group and 69 in NASH group. All included patients underwent psychometric tests which included number connection test A and B (NCT-A and NCT-B), serial dot test (SDT), digit symbol test (DST), line tracing test (LTT) and CFF. MHE was diagnosed when their PHES was <-4. RESULTS: the prevalence of MHE was significantly higher in ALD group compared to NASH (69.01% vs 40.58%; P=0.007). The performance of individual psychometric tests was significantly poorer in ALD (P<0.05). Overall sensitivity and specificity of CFF was 76.62% (95%CI 65.59 - 85.52) and 46.03% (95%CI 33.39 - 59.06) respectively. Mean CFF was significantly lower in ALD than NASH (37.07 (SD 2.37) vs 39.05 (SD 2.40), P=0.001); also in presence of MHE (36.95 (SD 2.04) vs 37.96 (SD 1.87), P=0.033) and absence of MHE (37.34 (SD 3.01) vs 39.79 (SD 2.46), P=0.001). CONCLUSION: MHE is significantly more common in patients with ALD cirrhosis than NASH counterparts. Overall CFF values are less in alcohol related cirrhosis than NASH related cirrhosis, even in presence or absence of MHE. We recommend additional caution in managing MHE in ALD cirrhosis.

Abstract. AIMS: The longitudinal relationship between depression and the risk of non-alcoholic fatty liver disease is uncertain. We examined: (a) the association between depressive symptoms and incident hepatic steatosis (HS), both with and without liver fibrosis; and (b) the influence of obesity on this association. METHODS: A cohort of 142 005 Korean adults with neither HS nor excessive alcohol consumption at baseline were followed for up to 8.9 years. The validated Center for Epidemiologic Studies-Depression score (CES-D) was assessed at baseline, and subjects were categorised as non-depressed (a CES-D < 8, reference) or depression (CES-D ⩾ 16). HS was diagnosed by ultrasonography. Liver fibrosis was assessed by the fibrosis-4 index (FIB-4). Parametric proportional hazards models were used to estimate the adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs). RESULTS: During a median follow-up of 4.0 years, 27 810 people with incident HS and 134 with incident HS plus high FIB-4 were identified. Compared with the non-depressed category, the aHR (95% CIs) for incident HS was 1.24 (1.15-1.34) for CES-D ⩾ 16 among obese individuals, and 1.00 (0.95-1.05) for CES-D ⩾ 16 among non-obese individuals (p for interaction with obesity <0.001). The aHR (95% CIs) for developing HS plus high FIB-4 was 3.41 (1.33-8.74) for CES-D ⩾ 16 among obese individuals, and 1.22 (0.60-2.47) for CES-D ⩾ 16 among non-obese individuals (p for interaction = 0.201). CONCLUSIONS: Depression was associated with an increased risk of incident HS and HS plus high probability of advanced fibrosis, especially among obese individuals.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease of immense public health relevance. Understanding illness perceptions in the NAFLD population will provide sound scientific evidence for planning high-quality patient-centered care and implementing effective interventions. The Brief Illness Perception Questionnaire (BIPQ) is a robust psychometric tool to systematically assess the dimensions of illness perceptions in various chronic ailments. METHODS: In a cross-sectional study enrolling patients with newly diagnosed NAFLD, the sociodemographic, anthropometric, biochemical, and radiological determinants of enhanced illness perceptions (measured by the BIPQ score) were investigated using univariate and multivariable binary logistic regression analyses. Finally, the association between individual domains of the BIPQ and willingness to participate in comprehensive medical management was explored. RESULTS: In total, 264 patients (mean age 53 ± 11.9 years, 59.8% males) were enrolled in the final analysis. The mean and median BIPQ scores in the study population were 30.3 ± 12.8 and 31.0 (IQR, 22.0-40.0), respectively. The variables having a significant independent association with heightened perceptions (BIPQ > 31) were family history of liver disease (aOR, 5.93; 95% CI, 1.42-24.74), obesity (aOR, 3.33; 95% CI, 1.57-7.05), diabetes mellitus (aOR, 2.35; 95% CI, 1.01-5.49), and transaminitis (aOR, 2.85; 95% CI, 1.42-5.69). Patients with a higher level of illness perceptions (31.6 ± 12.9 vs 27.8 ± 12.3, p = 0.022) were more likely to express a willingness to participate in the comprehensive management plan, with 3 of the 8 domains (consequence, identity, and treatment control) mainly affecting willingness. CONCLUSION: A family history of liver disease, obesity, diabetes, and transaminitis were independently associated with increased illness perceptions. A belief in serious consequences, a strong illness identity, and higher perceived treatment control were significantly associated with the willingness to undergo comprehensive care for NAFLD.

BACKGROUND: Opioid use is a topic of growing concern among patients with nonalcoholic fatty liver disease (NAFLD). Given safety concerns of opioids, proactively identifying subgroups of patients with an increased probability of opioid use may encourage practitioners to recommend alternative therapies for pain, thus reducing the likelihood of opioid misuse. This work assessed the prevalence and patient characteristics associated with opioid use in a real-world cohort of patients with NAFLD. METHODS: TARGET-NASH, an observational study of participants at 55 academic and community sites in the United States, includes patients with NAFLD defined by pragmatic case definitions. Opioid use was defined as any documented opioid prescriptions in the year prior to enrollment. The association between patient characteristics and the odds of opioid use were modeled with stepwise multivariable logistic regression and tree ensemble methods (Classification and regression tree/Boosted Tree). RESULTS: The cohort included 3,474 adult patients with NAFLD including 18.0% with documented opioid use. Variables associated with opioid use included presence of cirrhosis (OR 1.51, 95% CI 1.16-1.98), BMI ≥32 kg/m2 (OR 1.29, 95% CI 1.05-1.59), depression (OR 1.87, 95% CI 1.50-2.33), and anxiety (OR 1.59, 95% CI 1.27-1.98). In the boosted tree analysis, history of back pain, depression, and fibromyalgia had the greatest relative importance in predicting opioid use. CONCLUSION: Prescription opioids were used in nearly 1 of 5 patients with NAFLD. Given the safety concerns of opioids in patients with NAFLD, alternative therapies including low-dose acetaminophen and nonpharmacologic treatments should be considered for these patients.

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease worldwide and one of the leading causes of hepatocellular carcinoma and liver transplantation. Moreover, patients with NAFLD frequently complain of non-specific symptoms including fatigue, abdominal discomfort, as well as anxiety, and NAFLD is reported to affect patient-reported outcomes (PROs). Thus, for clarifying the total burden of NAFLD, it is crucial to assess all associated outcomes, including not only clinical and economic outcomes but also PROs. PROs are thought to reflect what is happening in one's daily life and is an important way patients and health-care professionals communicate. There are various instruments for the assessment of PROs. Recently, a NAFLD/non-alcoholic steatohepatitis (NASH)-specific instrument called "Chronic Liver Disease Questionnaire (CLDQ)-NAFLD/NASH" has been developed. CLDQ-NAFLD/NASH comprises six domains: (i) abdominal symptoms, (ii) activity/energy, (iii) emotional health, (iv) fatigue, (v) systemic symptoms, and (vi) worry. CLDQ-NAFLD/NASH has demonstrated excellent internal consistency, face validity, content validity, and test-retest reliability. It has been sufficiently validated in two international phase 3 clinical trials. In this review, we summarize features of various instruments for assessing PROs by focusing on CLDQ-NAFLD/NASH. We also examine the validity of CLDQ-NAFLD/NASH in Japanese patients and alterations in CLDQ-NAFLD/NASH score in Japanese patients with significant hepatic fibrosis. Moreover, we discuss the utility of CLDQ-NAFLD/NASH in phase 3 clinical trials and in a real-world clinical setting.

Non-alcoholic fatty liver disease (NAFLD) is an increasing problem in pediatrics with limited treatment options. We prospectively assessed outcomes in patients managed in a hepatology clinic (HC) alone vs. those managed in combination with a multidisciplinary weight management program (MWMP). We describe each group's readiness to change at the time of NAFLD diagnosis. Patients diagnosed with NAFLD were given a modified Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) at enrollment (T1) to assess readiness to change. They were then followed at 3-9 months (T2) and at 10-15 months (T3). Linear mixed models were used to evaluate changes in body mass index (BMI), BMI z-score, and transaminases over time and between the two groups. There were no significant treatment group main effects or treatment × time interactions for our primary end points for HC alone (n = 75) or with MWMP (n = 18). There was a significant main effect for time for BMI z-score, with BMI z-scores declining on average by 0.0568 (P = 0.004) from visit to visit. Low SOCRATES subscales scores in HC alone (n = 33) or with MWMP (n = 4) suggested a patient population with low recognition of disease and likelihood of taking steps for change. Patients with obesity and NAFLD had low scores on all three SOCRATES subscales. Despite this, both groups had improvement in BMI z-score without significant difference between the two treatment groups in other primary end points. Further study is needed to identify the most effective patient selection and treatment strategies for pediatric patients with NAFLD, including pharmacotherapy and surgery.

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) is the most common liver condition worldwide. A weight loss goal of ≥10% is the recommended treatment for NAFLD; however, only a minority of patients achieve this level of weight reduction with standard dietary approaches. This study aimed to determine whether a very low calorie diet (VLCD) is an acceptable and feasible therapy to achieve and maintain a ≥10% weight loss in patients with clinically significant NAFLD. METHODS: Patients with clinically significant NAFLD were recruited to a VLCD (â¼800 kcal/d) intervention using meal replacement products. Anthropometrics, blood tests (liver and metabolic), liver stiffness, and cardiovascular disease risk were measured at baseline, post-VLCD, and at 9-month follow-up. RESULTS: A total of 45 patients were approached of which 30 were enrolled 27 (90%) completed the VLCD intervention, and 20 (67%) were retained at 9-month follow-up. The VLCD was acceptable to patients and feasible to deliver. Intention-to-treat analysis found that 34% of patients achieved and sustained ≥10% weight loss, 51% achieved ≥7% weight loss, and 68% achieved ≥5% weight loss at 9-month follow-up. For those completing the VLCD, liver health (liver enzymes and liver stiffness), cardiovascular disease risk (blood pressure and QRISK2), metabolic health (fasting glucose, HbA1c, and insulin), and body composition significantly improved post-VLCD and was maintained at 9 months. DISCUSSION: VLCD offers a feasible treatment option for some patients with NAFLD to enable a sustainable ≥10%, weight loss, which can improve liver health, cardiovascular risk, and quality of life in those completing the intervention.
