Ultrasonographic Assessment of Tissue Stiffness: Recent Progress in Transient Elastography and Shear Wave Elastography in the Liver and Various Organs.

Ultrasonography is a noninvasive and widely accessible modality in clinical practice. Recently, ultrasonography has been used to evaluate tissue stiffness; the two representative techniques are transient elastography (FibroScan®) and shear wave elastography. These modalities are now generally used for the assessment of liver fibrosis, the prediction of hepatocarcinogenesis, and determining prognosis. In addition, shear wave elastography is available, not only for the liver but also for various other organs, including the breast and brain. In the breast and brain, shear wave elastography distinguishes malignant lesions from benign ones. Moreover, shear wave elastography can be useful for differentiating between ischemic and hemorrhagic strokes. This review summarizes the recent progress in transient elastography and shear wave elastography of the liver and introduces the advantages of ultrasonographic assessment of tissue stiffness in various organs, including the breast, brain, kidney, heart, thyroid, pancreas, muscle, and bone.

From Shadows to Spotlight: Exploring the Escalating Burden of Alcohol-Associated Liver Disease and Alcohol Use Disorder in Young Women.

INTRODUCTION: The burden of alcohol-related complications is considerable, particularly alcohol-associated liver disease and alcohol use disorder (AUD). However, there are deficiencies in comprehensive epidemiological research focusing on these issues, especially among young women who display higher susceptibility to such complications compared with their male counterparts. We thus aimed to determine the global burden of these conditions in this vulnerable group. METHODS: Leveraging data from the Global Burden of Disease Study 2019, we analyzed the prevalence, mortality, and disability-adjusted life years of alcohol-associated cirrhosis (AC), liver cancer from alcohol, and AUD in young women. The findings were categorized by region, nation, and sociodemographic index. RESULTS: The highest age-standardized prevalence rates were observed in AUD (895.96 [95% uncertainty interval (UI) 722.6-1,103.58]), followed by AC (65.33 [95% UI 48.37-86.49]) and liver cancer from alcohol (0.13 [95% UI 0.09-0.19]) per 100,000 people. The highest age-standardized mortality rates were observed in AC (0.75 [95% UI 0.55-0.97]), followed by AUD (0.48 [95% UI 0.43-0.53]) and liver cancer from alcohol (0.06 [95% UI 0.04-0.09]). The highest burdens of AC and AUD were observed in Central Europe, whereas the high-income Asia Pacific had the highest burden of liver cancer from alcohol. DISCUSSION: Throughout the past decade, the trend of AUD varied among regions while the impact of alcohol-associated liver disease has increased, requiring urgent public health strategy to mitigate these complications, particularly in female patients in Europe and the Asia-Pacific region.

The Incidence and Management of Cancer-Related Anorexia During Treatment with Vascular Endothelial Growth Factor Receptor-Tyrosine Kinase Inhibitors.

Cancer-related anorexia is a common complication and frequently occurs in cancer patients treated with vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs). Anorexia contributes to malnutrition, body weight loss, and cachexia in affected patients. Furthermore, patients who experience anorexia have worse outcomes than those who maintain their appetite, highlighting the importance of managing anorexia and related symptoms. However, as the causes of anorexia are both diverse and interconnected, there have been challenges in evaluating and implementing effective interventions. In this review, we described the contributing factors to cancer-related anorexia and reviewed recent literature for the frequency of anorexia symptoms in patients treated with VEGFR-TKIs. Additionally, we evaluated the evidence for current interventions and the potential benefits of multimodal and multidisciplinary approaches to care. The frequency of anorexia symptoms in patients who received VEGFR-TKIs ranged from 14%-58% for all-grade anorexia and 0%-6% for grade 3 or 4 anorexia. While many of the interventions for cancer-related anorexia have minimal benefit or adverse events, recent advances in our understanding of cancer-related anorexia suggest that multimodal therapy with multidisciplinary care is a promising avenue of investigation. Several studies currently underway are anticipated to further assess the effectiveness of multimodal approaches.

Subcutaneous Fat Thickness of the Lower Limb is Associated with Trunk Muscle Mass in Patients with Hepatocellular Carcinoma: A Simple Assessment for Sarcopenia Using Conventional Ultrasonography.

OBJECTIVE: Trunk muscle mass can be evaluated by skeletal muscle index (SMI), which is a prognostic factor in patients with hepatocellular carcinoma (HCC); however, this requires the use of computed tomography, and a simpler assessment for trunk muscle mass is urgently needed. We aimed to examine whether an association between SMI and lower extremity compartments including muscle and subcutaneous fat thickness of lower limbs (SFT-LL) could be identified by means of ultrasonography in patients with HCC. METHODS: We retrospectively enrolled male patients with HCC (n=30). Trunk muscle mass was evaluated by SMI using computed tomography. Ultrasonography was used for assessment of muscle and SFT-LL. Factors associated with SMI were evaluated by decision-tree analysis. RESULTS: There was no significant correlation between SMI and muscle thickness of lower limbs. However, a significant correlation was seen between SMI and left SFT-LL (r=0.406, P=0.026). In decision-tree analysis for SMI, left SFT-LL was selected as the initial split variable with an optimal cut-off value of 5 mm. In patients with left SFT-LL ≥ 5 mm, SMI was 39.4±3.4 cm2/m2, whereas SMI was 31.6±6.3 cm2/m2 in patients with left SFT-LL <5 mm. CONCLUSION: Left SFT-LL evaluated by ultrasonography was associated with SMI. Thus, ultrasonography may be a useful tool to evaluate trunk muscle mass. Moreover, left SFT-LL may be a useful indicator of sarcopenia in patients with HCC.

Patient-reported outcomes in patients with non-alcoholic fatty liver disease: A narrative review of Chronic Liver Disease Questionnaire-non-alcoholic fatty liver disease/non-alcoholic steatohepatitis.

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.

Prognostic impact of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation in patients with unresectable hepatocellular carcinoma: Comparison with TACE alone using decision-tree analysis after propensity score matching.

AIMS: The prognosis of hepatocellular carcinoma (HCC) patients treated with transcatheter arterial chemoembolization (TACE) is still poor. We aimed to evaluate the impact of TACE combined with radiofrequency ablation (TACE+RFA) on the prognosis of HCC patients using decision-tree analysis after propensity score matching. METHODS: This was a retrospective study. We enrolled 420 patients with HCC treated with TACE alone (n = 311) or TACE+RFA (n = 109) between 1998 and 2016 (median age, 72 years; male / female, 272/148; Barcelona Clinic Liver Cancer (BCLC) stage A / B, 215/205). The prognosis of patients who underwent TACE+RFA was compared to patients who underwent TACE alone after propensity score matching. Decision-tree analysis was used to investigate the profile for prognosis of the patients. RESULTS: After propensity score matching, there was no significant difference in age, sex, BCLC stage, or albumin-bilirubin (ALBI) score between both groups. The survival rate of the TACE+RFA group was significantly higher than the TACE alone group (median survival time [MST] 57.9 months vs. 33.1 months, P < 0.001). In a stratification analysis according to BCLC stage, the overall survival rate of the TACE+RFA group was significantly higher than the TACE alone group in BCLC stage A and B (MST 57.9 and 50.7 months vs. 39.8 and 24.5 months [P = 0.007 and 0.001], respectively). Decision-tree analysis showed that TACE+RFA was the third distinguishable factor for survival in patients with α-fetoprotein level >7 ng/mL and ALBI <-2.08. CONCLUSION: Decision-tree analysis after propensity score matching showed that TACE+RFA could prolong the survival of HCC patients compared to TACE alone.

Subjective global assessment is not sufficient to screen patients with defective hepatic metabolism.

BACKGROUND AND AIMS: Subjective global assessment (SGA) is useful for screening malnourished patients with several diseases, although it has been indicated to underestimate nutritional status for patients with liver disease. Accordingly, the aim of this study was to examine the usefulness of SGA as a nutritional screening tool for patients with liver disease, compared to patients with gastroenterological disease, without bias of personal ability and experience. METHODS: SGA was performed on 129 of hospitalized patients (86 with liver disease and 43 with gastroenterological disease). Nutritional status was categorized as well-nourished or malnourished status, based on nutritional indicators from laboratory data. RESULTS: The SGA screening ratio (sensitivity) for malnourished patients with liver disease was significantly lower than gastroenterological disease, while specificity or efficiency was not significantly different. In nutritional indicators from laboratory data, the difference between SGA-positive and SGA-negative patients with liver disease was significant but not so remarkable compared with the difference between those with other diseases. The positive number of SGA components per patient for the liver disease group was significantly less than gastroenterological disease group. CONCLUSIONS: SGA for patients with liver diseases was not sufficient as a nutritional screening tool because malnutrition induced by defective hepatic metabolism was not characterized fully.
