BaCKgRoUND aND aIMS: Real-world data for treatment effectiveness and renal outcomes in chronic hepatitis B (CHB) patients who were switched to the new and safer prodrug tenofovir alafenamide (TAF) from tenofovir disoproxil fumarate (TDF) are limited. Therefore, we aimed to evaluate treatment and renal outcomes of this population. appRoaCH aND ReSUltS:We analyzed 834 patients with CHB previously treated with TDF for ≥12 months who were switched to TAF in routine practice at 13 US and Asian centers for changes in viral (HBV DNA < 20 IU/mL), biochemical (alanine aminotransferase [ALT] < 35/25 U/L for male/female), and complete (viral+biochemical) responses, as well as estimated glomerular filtration rate (eGFR; milliliters per minute per 1.73 square meters) up to 96 weeks after switch. Viral suppression (P < 0.001) and ALT normalization (P = 0.003) rates increased significantly after switch, with a trend for increasing complete response (P trend = 0.004), while the eGFR trend (P trend > 0.44) or mean eGFR (P > 0.83, adjusted for age, sex, baseline eGFR, and diabetes, hypertension, or cirrhosis by generalized linear modeling) remained stable. However, among those with baseline eGFR < 90 (chronic kidney disease [CKD] stage ≥2), mean eGFR decreased significantly while on TDF (P = 0.029) but not after TAF switch (P = 0.90). By week 96, 21% (55/267) of patients with CKD stage 2 at switch improved to stage 1 and 35% (30/85) of CKD stage 3-5 patients improved to stage 2 and 1.2% (1/85) to stage 1.CoNClUSIoNS: Overall, we observed continued improvement in virologic response, ALT normalization, and no significant changes in eGFR following switch to TAF from TDF.

Because of the short hospital stay, the high clinical success rate, and the low adverse event rate compared to PCD, EUS-AD has potential as a first-line treatment for liver abscess.

Aging causes skeletal muscle atrophy, and myofiber loss can be a critical component of this process. In 1989, Rosenberg emphasized the importance of the loss of skeletal muscle mass that occurs with aging and coined the term 'sarcopenia'. Since then, sarcopenia has attracted considerable attention due to the aging population in developed countries. The presence of sarcopenia is closely related to staggering, falls and even frailty in the elderly, which in turn leads to the need for nursing care. Sarcopenia is often associated with a poor prognosis in the elderly. Therefore, it is crucial to investigate the causes and pathogenesis of sarcopenia, and to develop and introduce interventional strategies in line with these causes and pathogenesis. Sarcopenia can be a primary component of physical frailty. The association between sarcopenia, frailty and locomotive syndrome is complex; however, sarcopenia is a muscle-specific concept that is relatively easy to approach in research. In the elderly, a lack of exercise, malnutrition and hormonal changes lead to neuromuscular junction insufficiency, impaired capillary blood flow, reduced repair and regeneration capacity due to a decrease in the number of muscle satellite cells, the infiltration of inflammatory cells and oxidative stress, resulting in muscle protein degradation exceeding synthesis. In addition, mitochondrial dysfunction causes metabolic abnormalities, such as insulin resistance, which may lead to quantitative and qualitative abnormalities in skeletal muscle, resulting in sarcopenia. The present review article focuses on age-related primary sarcopenia and outlines its pathogenesis and mechanisms.

Background: Although atezolizumab plus bevacizumab (Atez/bev) treatment has been developed for unresectable hepatocellular carcinoma (u-HCC), changes in hepatic function during therapy have yet to be reported.

In cases of obstructive jaundice with duodenal obstruction, EUS-HGS may be better than EUS-CDS, with longer stent patency and fewer adverse events.

Background and aims Lenvatinib, a newly developed molecularly targeted agent, has become available for patients with unresectable hepatocellular carcinoma (HCC). Neutrophil‐to‐lymphocyte ratio (NLR) has been reported to be associated with poor outcomes in numerous malignancies. In this study, we investigated the impact of NLR on associating outcomes in patients with HCC treated with lenvatinib. Methods A total of 237 patients with HCC treated with lenvatinib were included. We performed univariate and multivariate analyses in this cohort. In addition, we clarified appropriate cut‐off NLR levels for associating overall survival using hazard ratio (HR) spline curves. Results Cumulative overall survival at 100, 200 and 300 days was 95.2%, 83.4% and 66.6% respectively. Multivariate analysis showed that NLR ≥ 4 (HR, 1.874; 95% confidence interval [CI], 1.097‐3.119), α‐foetoprotein ≥ 400 ng/mL (HR, 1.969; 95% CI, 1.188‐3.265) and modified albumin‐bilirubin grade 2b or 3 (HR, 2.123; 95% CI, 1.267‐3.555) were independently associated with overall survival. Cumulative progression‐free survival at 100, 200 and 300 days was 72.4%, 49.8% and 38.7% respectively. Multivariate analysis showed that NLR ≥ 4 (HR, 1.897; 95% CI, 1.268‐2.837) and BCLC stage ≥ C (HR, 1.516; 95% CI, 1.028‐2.236) were independently associated with progression‐free survival. Disease control rate was significantly different between the patients with low NLR (<4) (85.5%) and high NLR (≥4) (67.3%) (P = .007). Spline curve analysis revealed that NLR of approximately 3.0‐4.5 is an appropriate cut‐off for associating overall survival. Conclusions NLR can be associated with outcomes in patients with HCC treated with lenvatinib.

Nonalcoholic fatty liver disease (NAFLD) can develop into end-stage disease that includes cryptogenic cirrhosis and hepatocellular carcinoma. Bacterial endotoxin, for example lipopolysaccharide (LPS), plays an important role in the pathogenesis of NAFLD. The aim of this study was to assess the role of LPS in the development of NAFLD. Twenty-one male Zucker (fa/fa) rats were divided into three groups: rats fed for twelve weeks on a diet rich in disaccharide (D12 group), rats similarly managed but treated with LPS (LPS group), and those on the same diet for 24 weeks (D24 group). Histological examination demonstrated that this protocol induced hepatic steatosis in the LPS and D24 groups. Significant, marked accumulation of lipid droplets was observed in the LPS group, compared with the D24 group. Rats from the LPS group showed a decrease in plasma adiponectin levels, an increase in plasma leptin levels, and greater expression of FAS and SREBP-1c mRNA in the liver, compared with rats from the D24 group. These finding coincided with histological findings. We therefore suggest that LPS may accelerate the progression of hepatic steatosis.
