BACKGROUND: The study aimed to evaluate the risk of hepatitis C virus (HCV) infection on hepatic and extrahepatic deaths. METHODS: A cohort of 23 820 adults aged 30-65 years old were enrolled during 1991-1992. The seromarkers hepatitis B surface antigen (HBsAg), anti-HCV, and serum HCV RNA levels at study entry were tested. The vital status was ascertained through computerized linkage with national death certification profiles from 1991 to 2008. RESULTS: There were 19,636 HBsAg-seronegatives, including 18,541 anti-HCV seronegatives and 1095 anti-HCV seropositives. Among anti-HCV seropositives, 69.4% had detectable serum HCV RNA levels. There were 2394 deaths that occurred during an average follow-up period of 16.2 years. Compared with anti-HCV seronegatives, anti-HCV seropositives had higher mortality from both hepatic and extrahepatic diseases, showing multivariate-adjusted hazard ratio (95% confidence interval) of 1.89 (1.66-2.15) for all causes of death; 12.48 (9.34-16.66) for hepatic diseases; 1.35 (1.15-1.57) for extrahepatic diseases; 1.50 (1.10-2.03) for circulatory diseases; 2.77 (1.49-5.15) for nephritis, nephrotic syndrome, and nephrosis; 4.08 (1.38-12.08) for esophageal cancer; 4.19 (1.18-14.94) for prostate cancer; and 8.22 (1.36-49.66) for thyroid cancer. Anti-HCV seropositives with detectable HCV RNA levels had significantly higher mortality from hepatic and extrahepatic diseases than anti-HCV seropositives with undetectable HCV RNA. CONCLUSIONS: Monitoring HCV RNA in anti-HCV seropositives is essential for the prediction of mortality associated with hepatitis C. [ABSTRACT FROM AUTHOR]

OBJECTIVE/AIM: Hepatocellular carcinoma (HCC) surveillance is a common practice for patients with liver cirrhosis. The aims of the study were to assess impacts of surveillance and therapeutic options on survival of patients with HCC. METHODS: A total of 1436 cirrhotic patients with newly diagnosed HCC were enrolled between January 2002 and December 2004. Patients with HCC detected within periodic surveillance were the surveillance group (n=318, 22.1%). The other patients with HCC incidentally detected were the non-surveillance group (n=1118, 77.95%). Initial treatment options were recorded and overall survival was analysed. RESULTS: Compared with patients in the non-surveillance group, larger proportions of patients in the surveillance group possessed small tumours, at an early stage without vascular invasion or metastases, and afforded more curative treatment options including surgical resection, radiofrequency ablation and percutaneous ethanol injection. The overall survival was better for patients in surveillance (3-year survival rate: 59.1% versus 29.3%, p<0.001), early stages by Barcelona Clinic Liver Cancer (BCLC) staging or curative treatment options. Multivariate analysis demonstrated surveillance, hepatitis aetiology, alpha-fetoprotein, tumour gross type, tumour stage and treatment options were associated factors for patients' survival. Moreover, surveillance patients in curative BCLC stage following the treatment guideline for HCC proposed by the American association for the study of liver disease (AASLD) had a significantly better 3-year survival rate (77.1% versus 55.2%, p<0.001). CONCLUSIONS: HCC surveillance for cirrhotic patients could detect HCC at early and curative stages. However, appropriate treatment options following AASLD guideline further improve the survival for patients in early stage. [ABSTRACT FROM AUTHOR]

The Barcelona Clinic Liver Cancer (BCLC) staging offers prognostic stratification and treatment allocation for hepatocellular carcinoma (HCC). We conducted this retrospective study to assess the efficacy of different treatment options for patients with initial HCC diagnosis. Survival rate and median survival times associated with different treatment options in each stage of BCLC classification were compared using the Kaplan-Meier method and log-rank test. A total of 3892 patients were enrolled. Overall survival rates were 46.2% at 1 year and 16.6% at 5 years. The median survival times decreased from 57.7 months in very early stage to 1.6 months in terminal stage. Surgical resection offered the best survival benefit for patients in very early, early and even intermediate stages. Transarterial embolisation and conformal radiotherapy offered survival benefits for selected patients in advanced and terminal stages. In conclusion, following the treatment schedules allocated by BCLC staging had survival benefits for HCC patients. [ABSTRACT FROM AUTHOR]

Introduction: The prospective study aimed to investigate the long-term associated risks of cirrhosis and hepatocellular carcinoma (HCC) across various subtypes of steatotic liver disease (SLD)., Methods: We enrolled 332,175 adults who participated in a health screening program between 1997 and 2013. Participants were categorized into various subtypes, including metabolic dysfunction-associated SLD (MASLD), MASLD with excessive alcohol consumption (MetALD), and alcohol-related liver disease (ALD), based on ultrasonography findings, alcohol consumption patterns, and cardiometabolic risk factors. We used computerized data linkage with nationwide registries from 1997 to 2019 to ascertain the incidence of cirrhosis and HCC., Results: After a median follow-up of 16 years, 4,458 cases of cirrhosis and 1,392 cases of HCC occurred in the entire cohort, resulting in an incidence rate of 86.1 and 26.8 per 100,000 person-years, respectively. The ALD group exhibited the highest incidence rate for cirrhosis and HCC, followed by MetALD, MASLD, and non-SLD groups. The multivariate adjusted hazard ratios for HCC were 1.92 (95% confidence interval [CI] 1.51-2.44), 2.91 (95% CI 2.11-4.03), and 2.59 (95% CI 1.93-3.48) for MASLD, MetALD, and ALD, respectively, when compared with non-SLD without cardiometabolic risk factors. The pattern of the associated risk of cirrhosis was similar to that of HCC (all P value <0.001). The associated risk of cirrhosis for ALD increased to 4.74 (95% CI 4.08-5.52) when using non-SLD without cardiometabolic risk factors as a reference., Discussion: This study highlights elevated risks of cirrhosis and HCC across various subtypes of SLD compared with non-SLD, emphasizing the importance of behavioral modifications for early prevention., (Copyright © 2024 The Author(s).

Purpose: To explore the potential of a novel approach to simplify risk assessment by comparing carotid artery velocities with current atherosclerotic cardiovascular disease (ASCVD) risk stratification method using nonlinear measurements., Methods: In this prospective study conducted at a medical center in southern Taiwan from January 1, 2020, to December 31, 2021, 1636 participants aged 40-75 years without prior ASCVD events were enrolled. Carotid flow velocity was obtained through duplex ultrasonography. ASCVD risk was categorized into two groups according to the 2022 USPSTF guidelines for primary prevention. We analyzed associations between flow indices and ASCVD risk using logistic regression and generalized additive models (GAMs)., Results: The end diastolic velocity (EDV) of common carotid artery (CCA) and the peak systolic velocity (PSV) of internal carotid artery (ICA) were inversely and nonlinearly associated with cardiovascular event risk. Multivariate logistic regression analysis with ROC curves revealed that the optimal speed for the EDV of CCA was approximately 23.75 cm/s, and the optimal PSV and EDV of ICA were approximately 81.75 cm/s and 26.75 cm/s, respectively. The GAMs showed U-shaped relationships between elevated ASCVD risk and blood flow velocity in the carotid arteries, with inflection points of approximately 82 cm/s in the PSV of ICA and near 25 cm/s in the EDV of CCA. Both methods revealed similar results., Conclusions: The EDVs and PSVs of the CCA and ICA are associated with the development of cardiovascular events. Optimal velocity ranges were identified; however, further hemodynamic investigations are warranted., (© 2024. The Author(s).)

To clarify the survival benefit of sequential curative treatment post transcatheter arterial chemoembolization (TACE) for Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC), we retrospectively analyzed HCC patients at a hospital. From July 2017 to July 2020, 787 treatment-naïve HCC patients underwent initial treatment; 77 (9.8%) meeting inclusion criteria were enrolled. Their initial treatments were TACE only (n = 68, 88.3%) or TACE with other treatments (n = 9, 11.7%). Median survival of the TACE-only group was 30 months. Treatment response was evaluated after 2 or 3 consecutive TACEs for patients (54/68, 79.4%) with available pre-/post-TACE computerized tomography (CT) or magnetic resonance imaging (MRI). Treatment responses was divided into 4 groups: complete (n = 14, 26%, group (Gr) 1), incomplete without new tumor growth (n = 28, 52.0%, Gr2), incomplete with new growth (n = 6, 11%, Gr3), and progression (n = 6, 11%, Gr4). Of Gr2, further treatment after TACE were had radiofrequency ablation (n = 13, Gr2a), TACE (n = 9, Gr2b), other modalities (n = 6, Gr2c. Gr2a's median survival was longer than Gr2b's (> 60 vs. 20 months, p = 0.007). Nine patients in Gr2a (69%, 9/13) achieved a complete response, but none in Gr2b (p = 0.001). Conclusively, in TACE-suitable BCLC stage B HCC patients, a partial response without new tumor growth can serve as an indicator of treatment effectiveness following initial TACE treatment. This can facilitate the selection of appropriate candidates to receive RFA, potentially resulting in improved patient survival., (© 2024. The Author(s).)

Background and Aim: This study estimated the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) according to cardiometabolic risk factors. The long-term impacts of MASLD on all-cause and cardiometabolic-specific mortality were evaluated., Methods: We enrolled 343 816 adults aged ≥30 years who participated in a health screening program from 1997 through 2013. MASLD was identified on the basis of abdominal ultrasonography and metabolic profiles. The participants were further categorized by liver enzyme elevation. Baseline cardiometabolic comorbidities were classified on the basis of self-reported medication use and clinical seromarkers. All-cause and cardiometabolic-specific deaths were determined through computerized data linkage with nationwide death certifications until December 31, 2020., Results: The overall prevalence of MASLD was 36.4%. Among patients with MASLD, 35.9% had abnormal liver enzyme levels. Compared with patients without MASLD, abnormal liver enzymes were positively associated with cardiometabolic comorbidities in patients with MASLD (P for trend  < 0.001). After follow-up, patients with MASLD had a 9%-29% higher risk of all-cause, cardiovascular-related, or diabetes-related mortality. In the groups with MASLD and elevated and normal liver enzyme levels, the multivariate-adjusted hazard ratios for cardiovascular deaths were 1.14 (1.05-1.25) and 1.10 (1.03-1.17), respectively, and those for diabetes deaths were 1.42 (1.05-1.93) and 1.24 (0.98-1.57), respectively, compared with those in the non-MASLD group (P for trend  < 0.001)., Discussion: Individuals with MASLD and elevated liver enzyme levels exhibited significantly higher risks of all-cause and cardiometabolic deaths and should be monitored and given consultation on cardiometabolic modifications., (© 2024 The Authors.

Purpose: Previous research shows conflicting views on the relationship between obesity and osteoporosis, partly due to variations in obesity classification and the nonlinear nature of these relationships. This study investigated the association between adiposity indices and osteoporosis, diagnosed using dual-energy X-ray absorptiometry (DXA), employing nonlinear models and offering optimal thresholds to prevent further bone mineral density decline., Methods: In 2019, a prospective study enrolled males over 50 years and postmenopausal women. Anthropometric measurements, blood biochemistry, and osteoporosis measured by DXA were collected. Associations between adiposity indices and osteoporosis were analyzed using a generalized additive model and segmented regression model., Results: The study included 872 women and 1321 men. Indices such as abdominal volume index (AVI), visceral adiposity index (VAI), waist circumference (WC), hip circumference, body mass index (BMI), waist-to-hip ratio, and waist-to-height ratio (WHtR) were inversely associated with osteoporosis. In women, the relationship between the risk of osteoporosis and the adiposity indices was U-shaped, with thresholds of WC = 94 cm, AVI = 17.67 cm 2 , BMI = 25.74 kg/m 2 , VAI = 4.29, and WHtR = 0.61, considering changes in bone mineral density. Conversely, men exhibited a linear patterns for the inverse association., Conclusion: The impact of obesity and adiposity on osteoporosis varies significantly between women and men. In postmenopausal women, the relationship is nonlinear (U-shaped), with both very low and very high adiposity linked to higher osteoporosis risk. In men over 50, the relationship is linear, with higher adiposity associated with lower osteoporosis risk. The study suggests that maintaining specific levels of adiposity could help prevent osteoporosis in postmenopausal women., (© 2024. The Author(s).)

Purpose: In several Asian countries, hepatocellular carcinoma (HCC) is a leading cause of cancer deaths. HCC risk factors in Asia differ from those elsewhere and are changing with the treatment landscape as systemic treatment options increase. This study was conducted to gain insight from physicians and patients into HCC screening, diagnosis, and treatment strategies in Indonesia, Korea, Malaysia, Singapore, Taiwan, Thailand, and Vietnam., Methods: Two cross-sectional, anonymized, online surveys were completed between July and December 2022 by physicians diagnosing and treating HCC (55 questions on risk factors, surveillance, diagnosis, and treatment) and patients ≥ 18 years old diagnosed with HCC (36 questions on disease knowledge, quality of life, and experiences of diagnosis and treatment)., Results: Responses were received from 276 physicians in all 7 countries and 130 patients in Thailand, Taiwan, and Vietnam. From the physician's perspective, surveillance programs are widespread but identify insufficient HCC cases; only 18% are early-stage HCC at diagnosis. From the patient's perspective, knowledge of risk factors increases after diagnosis, but few seek support from patient associations; patients would benefit from better communication from their doctors. Treatment affordability and side effects are key issues for patients., Conclusions: Awareness of the risk factors for HCC should be raised in primary care and the general population, and surveillance should identify early-stage HCC. Because patients rely on their doctors for support, doctors should better understand their patients' needs, and patients could be supported by trained nurses or case managers. Programs are needed to increase patients' access to proven HCC treatments., (© 2024. The Author(s).)

Background & Aims: The impact of metabolic dysfunction-associated steatotic liver disease (MASLD) on the development of cirrhosis and hepatocellular carcinoma (HCC) by chronic hepatitis B (CHB) or C infection and antiviral treatment statuses is not well-known., Methods: A total of 336,866 adults aged ≥30 years were prospectively enrolled in a health screening program between 1997-2013. MASLD was identified by abdominal ultrasonography and cardiometabolic profiles. Data linkage was performed using 3 nationwide databases-National Health Insurance, Cancer Registry, and Death Certification System-to obtain information on antiviral treatment, vital status, and newly diagnosed cirrhosis and HCC. Follow-up was conducted until December 31, 2019., Results: In the total population, 122,669 (36.4%) had MASLD. Over a mean follow-up of 15 years, 5562 new cases of cirrhosis and 2273 new cases of HCC were diagnosed. Although MASLD significantly increased the cumulative risks of cirrhosis or HCC (P < .0001), the associated risk was more pronounced when comparing CHB or C infection with the presence of MASLD. Stratifying the participants based on their MASLD and CHB or C statuses, hazard ratios (HR adj ) with 95% confidence intervals for HCC were 8.81 (7.83-9.92) for non-steatotic liver disease (SLD) with CHB or C, 1.52 (1.32-1.74) for MASLD without CHB or C, and 8.86 (7.76-10.12) for MASLD with CHB or C, compared with non-SLD without CHB or C (all P < .0001). Among CHB or C patients who received antivirals during follow-up, MASLD was associated with increased risks of cirrhosis and HCC, with HR adj of 1.23 (1.01-1.49) and 1.32 (1.05-1.65), respectively., Conclusions: These findings underscore the need to prioritize treatment of chronic viral hepatitis before addressing MASLD., (Copyright © 2024 AGA Institute.

Dopamine D2 receptors (D2Rs) play crucial roles in regulating diverse physiological functions of the central nervous system and peripheral organs. D2Rs are also expressed in mammary glands. However, which cell types express D2Rs and whether they are involved in milk production remains unclear. The present findings revealed that D2Rs are expressed in the apical regions of the lateral membranes of mammary epithelial cells (MECs) in lactating mice. We also investigated the effects of the D2R agonist bromocriptine and/or antagonist domperidone on intracellular cAMP levels, milk protein production, and apoptosis in a lactation culture model of MECs that produce major milk components like lactating MECs in vivo. We found that bromocriptine decreased intracellular cAMP levels, whereas domperidone dose-dependently neutralized this effect. Bromocriptine also inhibited casein and lactoferrin production and suppressed activities of STAT5 and glucocorticoid receptors (GRs). Domperidone neutralized the inhibition of casein production as well as STAT5 and GR inactivation induced by bromocriptine. Furthermore, D2R activation by bromocriptine induced apoptosis and inactivated ERK, a signaling molecule responsible for promoting cell proliferation and survival. Domperidone attenuated ERK inactivation and apoptosis induced by bromocriptine. These findings suggest that D2Rs play regulatory roles in milk protein production and apoptosis in MECs., Competing Interests: Declaration of competing interest The authors declare that they have no conflicts of interest., (Copyright © 2024 Elsevier Inc.

In 2008, sorafenib became the first approved systemic therapeutic agent for advanced HCC. Although its pharmacological efficacy has been established, reimbursement for such a new, high-cost drug, as well as physicians' awareness and prescription practice, likewise contribute to its clinical effectiveness. We therefore conducted a retrospective study using 38 sorafenib-eligible, advanced HCC patients when sorafenib was approved but not yet reimbursed as a control and 216 patients during the reimbursed era. Study group showed longer survival at 8.2 months versus the control's 4.9 months (p = 0.0063 hazard ratio: 0.612 [0.431 ~ 0.868], p = 0.0059). Among the 42 (19.4%) patients who survived more than 2 years, 50% had tumor rupture, and all 32 patients with portal vein tumor thrombus and/or extrahepatic metastasis received sorafenib (p = 0.003). Furthermore, during their first 2 years of HCC management, sorafenib had been given in 29.1% of the treatment courses among survivors between 2 and 5 years while it was prescribed in 55.8% among the more than 5 years survivor group (p < 0.001). In conclusion, survival of sorafenib-eligible HCC patients significantly improved after reimbursement. Patients who underwent longer sorafenib treatment had a survival advantage, except for those with tumor rupture. Reimbursement and awareness of prescriptions for a newly introduced medication therefore improve clinical effectiveness., (© 2024 The Authors.

Whether serum Mac-2 binding protein glycosylation isomer (M2BPGi) level at year 5 of treatment could predict hepatocellular carcinoma (HCC) development and mortality beyond year 5 of entecavir or tenofovir disoproxil fumarate (TDF) treatment in chronic hepatitis B (CHB) patients with cirrhosis remain unclear. This retrospective study investigated the role of M2BPGi level at year 5 of treatment in predicting HCC and mortality beyond year 5 in CHB patients with cirrhosis. This study analyzed 1385 cirrhotic patients receiving entecavir or TDF treatment. Of them, 899 patients who did not develop HCC within the first 5 years of treatment were enrolled. In the entire cohort, there was no significant difference in the annual incidence of HCC before and after year 5 of entecavir or TDF treatment ( P = 0.455). Multivariable Cox analysis identified old age, higher AFP and M2BPGi levels at 5 years of treatment as independent predictors of HCC occurrence beyond year 5. We developed the HCC risk prediction model, AMA, based on age, M2BPGi and AFP levels at 5 years of treatment, with the total score ranging from 0 to 8. The AMA model accurately categorized patients into low (≤2), medium (2-5), and high (≥5) risk groups in the development and validation groups ( P <0.001) and exhibited good discriminant function in predicting HCC beyond year 5 in cirrhotic patients (AUROC: 0.743 at 5 years). The M2BPGi of 1.0 COI at 5 years of treatment stratified the risk of all-cause and liver-related mortality beyond year 5 ( P <0.001). In conclusions, M2BPGi level at 5 years of treatment is a useful marker for predicting HCC development and mortality beyond year 5 of entecavir or TDF therapy in CHB patients with cirrhosis., Competing Interests: Cheng-Yuan Peng has served as an advisory committee member for AbbVie, Bristol-Myers Squibb, Gilead, Merck Sharp & Dohme, and Roche., (AJCR Copyright © 2024.)

Background: /Purpose: To achieve the World Health Organization goal of eliminating viral hepatitis by 2030, a key strategy in resource-limited areas is to identify the areas with high prevalence and to prioritize screening and treatment intervention. We hypothesized that a hospital-based laboratory database could be used to estimate the township- and village-specific anti-hepatitis C virus (HCV) prevalence., Methods: Yunlin County Public Health Bureau has been collecting anti-HCV test data from eight major hospitals. Township- and village-specific screening testing rates and anti-HCV prevalence were calculated for residents 40 years or older. A township with a wide range of anti-HCV prevalence rates was selected for outreach universal screening and for validating the village-specific prevalence of anti-HCV in the analysis of the data from the hospitals., Results: The overall anti-HCV screening testing rate in Yunlin County was 30.4 %, whereas the anti-HCV prevalence rate for persons 40 years or older was 15.4 %. The village-specific anti-HCV prevalence rates ranged from 3.8 % to 85.8 %. Community-based screening was conducted in Kouhu Township. The village-specific anti-HCV prevalence rates ranged from 0 % to 18.8 %. Three of the four villages had the highest village-specific anti-HCV prevalence in the community-based study and the hospital-based study. Additionally, 95.8 % of the new HCV cases detected by universal screening received anti-HCV therapy., Conclusion: The hospital-based database provided a framework for identifying the villages with high anti-HCV prevalence. Additionally, community-based universal screening should be prioritized for villages with high prevalence in hospital-based databases., Competing Interests: Declaration of competing interest All authors have no conflicts of interest to declare., (Copyright © 2024 Formosan Medical Association.

Background: No study has comparing hepatitis B virus (HBV) relapse rates among patients with both cancer and hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) who completed anti-viral prophylaxis for chemotherapy and then stopped taking entecavir or tenofovir alafenamide (TAF)., Methods: A total of 227 HBeAg-negative cancer patients without cirrhosis who previously took entecavir (n = 144) or TAF (n = 83) for antiviral prophylaxis were enrolled., Results: The cumulative incidence of virological and clinical relapse at 2 years was 37% and 10.4%, respectively, in the entecavir group, and 46.7% and 19.5%, respectively, in the TAF group. The multivariate analysis revealed that the use of hematologic malignancy, TAF use, and high-viremia group at baseline were independent risk factors for virological relapse, and use of rituximab, TAF use, higher FIB-4 index and high-viremia group at baseline were independent risk factors for clinical relapse. After propensity score-matching, the patients who discontinued TAF therapy still exhibited higher virological (P = 0.031) and clinical relapse rates (P = 0.012) than did those who discontinued entecavir therapy. The patients were allocated to high- (> 2000 IU/mL), moderate- (between 20 and 2000 IU/mL) and low- (< 20 IU/mL) viremia groups. In the high-viremia group, those who had taken TAF for antiviral prophylaxis had higher rates of virological and clinical relapse than did those who had taken entecavir; in the moderate- and low-viremia groups, no significant difference in virological and clinical relapse rates was detected between the entecavir and TAF groups. Three patients experienced hepatic decompensation upon clinical relapse. All three patients were lymphoma and underwent rituximab therapy. One patient developed acute on chronic liver failure and died even though timely retreatment., Conclusions: In patients with both cancer and CHB who underwent antiviral prophylaxis, TAF use was associated with a higher chance of HBV relapse than entecavir use after nucleos(t)ide analogue cessation, particularly in the high-viremia group. Patients who are hematologic malignancy and undergo a rituximab-containing cytotoxic therapy should be monitored closely after withdrawal from prophylactic NA treatment., (© 2024. The Author(s).)

Background: High hepatitis B surface antigen (HBsAg) level predicts hepatocellular carcinoma (HCC) in chronic hepatitis B (CHB) patients with low viral load. The role of longitudinal HBsAg levels in predicting HCC in HBeAg-positive CHB patients remains unknown., Method: HBeAg-positive CHB participants from the REVEAL-HBV cohort with ≥2 HBsAg measurements before HBeAg seroclearance were enrolled. Group-based trajectory modelling identified distinct HBsAg trajectory groups during a median of 11 years of HBeAg-positive status. Cox regression models were applied for investigating independent predictors of HCC and estimating adjusted hazard ratio (HR adj ) with a 95% confidence interval (CI). A p-value less than 0.05 was considered statistically significant., Results: A total of 319 patients were enrolled and classified by HBsAg trajectory patterns as (A) persistently high group (n = 72): HBsAg persistently ≥10 4  IU/mL, and (B) non-stationary group (n = 233): low HBsAg at baseline or declining to <10 4  IU/mL during the follow-up. Group B had higher proportions of abnormal ALT levels, HBV genotype C and basal core mutation than group A (p < 0.05); age at entry and gender were comparable. The annual incidence of HCC in group A and group B were 0.37% and 1.16%, respectively (p = 0.03). In multivariate analysis, age >40 years (HR adj [95% CI] = 4.11 [2.26-7.48]), genotype C (HR adj [95% CI] = 4.39 [1.96-9.81]) and the non-stationary group (HR adj [95% CI] = 3.50 [1.49-8.21]) were independent predictors of HCC. Basal core promoter mutation was the only risk factor of HCC in the persistently high HBsAg group (HR adj [95% CI] = 32.75 [5.41-198.42])., Conclusion: Patients with persistently high HBsAg levels during HBeAg-seropositive stage represent a unique population with low risk of HCC development., (© 2024 John Wiley & Sons Ltd.)

Few studies have reported weight gain in patients with hepatitis C virus (HCV) infection treated with direct-acting antiviral agents (DAAs). This retrospective cohort study identified factors associated with substantial weight gain after DAA treatment in Taiwan. This study involved patients treated using DAAs at the Chiayi and Yunlin branches of Chang Gung Memorial Hospital from 1 January 2017 to 31 October 2020. Body weight data were collected at the start of DAA therapy and 2 years after the confirmation of a sustained virologic response. We performed multiple logistic regression to evaluate the clinical and laboratory parameters associated with a large body mass index (BMI) increase (≥5%). The mean BMI was 25.56 ± 4.07 kg/m 2 at baseline and 25.77 ± 4.29 kg/m 2 at the endpoint ( p = 0.005). A considerable reduction in fibrosis-4 (FIB-4) score was a significant predictor of a large BMI increase (OR: 1.168; 95% CI: 1.047-1.304, p = 0.006). By contrast, older age (OR: 0.979; 95% CI: 0.963-0.996, p = 0.013) and a higher baseline BMI (OR: 0.907; 95% CI: 0.863-0.954, p < 0.001) were associated with a reduced risk of a large increase in BMI at the endpoint. In summary, a larger BMI increase was closely associated with a younger age, lower baseline BMI, and higher FIB-4 score reduction. Notably, differences in DAA regimens did not affect outcomes. Future studies are needed to elucidate the long-term effects and metabolic outcomes associated with this body weight change and investigate the exact underlying mechanisms.

The human neuroblastoma cell lines SH-SY5Y and IMR-32 can be differentiated into neuron-like phenotypes through treatment with all- trans -retinoic acid (ATRA). After differentiation, these cell lines are extensively utilized as in vitro models to study various aspects of neuronal cell biology. However, temporal and quantitative profiling of the proteome and phosphoproteome of SH-SY5Y and IMR-32 cells throughout ATRA-induced differentiation has been limited. Here, we performed relative quantification of the proteomes and phosphoproteomes of SH-SY5Y and IMR-32 cells at multiple time points during ATRA-induced differentiation. Relative quantification of proteins and phosphopeptides with subsequent gene ontology analysis revealed that several biological processes, including cytoskeleton organization, cell division, chaperone function and protein folding, and one-carbon metabolism, were associated with ATRA-induced differentiation in both cell lines. Furthermore, kinase-substrate enrichment analysis predicted altered activities of several kinases during differentiation. Among these, CDK5 exhibited increased activity, while CDK2 displayed reduced activity. The data presented serve as a valuable resource for investigating temporal protein and phosphoprotein abundance changes in SH-SY5Y and IMR-32 cells during ATRA-induced differentiation.

Background: Progress in malaria control has stalled in recent years and innovative surveillance and response approaches are needed to accelerate malaria control and elimination efforts in endemic areas of Africa. Building on a previous China-UK-Tanzania pilot study on malaria control, this study aimed to assess the impact of the 1,7-malaria Reactive Community-Based Testing and Response (1,7-mRCTR) approach implemented over two years in three districts of Tanzania., Methods: The 1,7-mRCTR approach provides community-based malaria testing via rapid diagnostic tests and treatment in villages with the highest burden of malaria incidence based on surveillance data from health facilities. We used a difference-in-differences quasi-experimental design with linear probability models and two waves of cross-sectional household surveys to assess the impact of 1,7-mRCTR on malaria prevalence. We conducted sensitivity analyses to assess the robustness of our results, examined how intervention effects varied in subgroups, and explored alternative explanations for the observed results., Results: Between October 2019 and September 2021, 244,771 community-based malaria rapid tests were completed in intervention areas, and each intervention village received an average of 3.85 rounds of 1-7mRCTR. Malaria prevalence declined from 27.4% at baseline to 11.7% at endline in the intervention areas and from 26.0% to 16.0% in the control areas. 1,7-mRCTR was associated with a 4.5-percentage-point decrease in malaria prevalence (95% confidence interval: - 0.067, - 0.023), equivalent to a 17% reduction from the baseline. In Rufiji, a district characterized by lower prevalence and where larviciding was additionally provided, 1,7-mRCTR was associated with a 63.9% decline in malaria prevalence., Conclusions: The 1,7-mRCTR approach reduced malaria prevalence. Despite implementation interruptions due to the COVID-19 pandemic and supply chain challenges, the study provided novel evidence on the effectiveness of community-based reactive approaches in moderate- to high-endemicity areas and demonstrated the potential of South-South cooperation in tackling global health challenges., (© 2023.

Mammary epithelial cells (MECs) secrete milk into the mammary alveolar lumen during lactation. The secreted milk accumulates in the alveolar lumen until milk ejection occurs, and excess milk accumulation downregulates milk production in alveolar MECs. Intramammary hydrostatic pressure also increases in the alveolar lumen in a manner dependent on milk accumulation. In this study, we investigated whether high hydrostatic compression directly affects lactating MECs, using a commercial compression device and a lactation culture model of MECs, which have milk production ability and less permeable tight junctions. High hydrostatic compression at 100 kPa for 8 h decreased β-casein and increased claudin-4 levels concurrently with inactivation of STAT5 and glucocorticoid receptor signaling pathways. In addition, high hydrostatic compression for 1 h inactivated STAT5 and activated p38 MAPK signaling. Furthermore, repeated rises and falls of the hourly hydrostatic compression induced activation of positive (Akt, mTOR) and negative (STAT3, NF-κB) signaling pathways for milk production concurrently with stimulation of casein and lactoferrin production in MECs. These results indicate that milk production-related signaling pathways in MECs change in response to hydrostatic compression. Hydrostatic compression of the alveolar lumen may directly regulate milk production in the alveolar MECs of lactating mammary glands., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

The estimated prevalence of anti-HCV was 3.1% in Taiwan. Studies have shown iatrogenic behavior was the major transmission route. It is highest in specific populations including patients with end stage renal disease (ESRD), human immunodeficiency virus infection, who inject drug (PWID), and under opioid substitution treatment. Approximately 405,160 patients were seropositive for HCV RNA and in need of treatment. Taiwan government claims to reach WHO's 2030 goal of HCV elimination by 2025 and works hard to resolve several barriers of HCV elimination including political commitment, sustainable financing, minimize reimbursement restrictions, instituted monitoring, and perform micro-elimination of specific populations. The last stage of HCV elimination is to accelerate the universal HCV screening program of populations aged 45-79 years and resolve the unawareness issue of HCV infection. Hopefully, we can achieve the targets of HCV elimination set by WHO and reach the goal earlier in 2025., (© The Author(s) 2023.

Background and Aims: Magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF) is the reference standard of hepatic steatosis assessment. This study evaluates usefulness of controlled attenuation parameter (CAP) in monitoring the clinically relevant outcome by MRI-PDFF for non-alcoholic fatty liver disease (NAFLD) patients., Methods: NAFLD patients were enrolled prospectively. Instruction was given in lifestyle modifications with exercise and control of metabolic factors. MRI-PDFF and CAP were performed at enrollment and follow-up, with the diagnostic validity of CAP in monitoring clinically relevant outcome defined as a decline of ≥30% relative to baseline value by MRI-PDFF., Results: A total of 75 patients (male/female: 49/26, mean age: 53.2) were enrolled. Baseline MRI-PDFF, CAP and liver stiffness was 14.4%, 300.2 dB/m and 6.5 kPa. In a median interval of 369 days, thirteen (17.3%) patients achieved clinically relevant outcome with decline of 46.7 dB/m by CAP, compared with increase of 5.1 in the other patients. In multivariate analysis, clinically relevant outcome was associated with changes (Δ) of CAP and glucose. Assessed by area under receiver operating curve, the performances of ΔCAP in predicting clinically relevant outcome were 0.815 and 0.808, and with the specificity of >90%, the ΔCAP cutoff was -46 dB/m and -15% relative to baseline value; sensitivity was 53.8% and 46.2% with negative predictive value of 90.3% and 88.9% respectively., Conclusions: For NAFLD patients, CAP exhibited good performance in monitoring clinically relevant decline of hepatic steatosis in MRI-PDFF. With the cutoffs of -46 dB/m or -15%, ΔCAP is useful in excluding clinical relevant outcome achievement., (© 2023 John Wiley & Sons Ltd.)

Background/aims: Little is known about the role of post-treatment HBsAg decline in HBsAg loss following nucleos(t)ide analogues cessation., Methods: HBeAg-negative patients without cirrhosis who previously received entecavir or tenofovir disoproxil fumarate (TDF) were enrolled (n=530). All patients were followed-up post-treatment for >24 months., Results: Of the 530 patients, 126 achieved sustained response (Group I), 85 experienced virological relapse without clinical relapse and retreatment (Group II), 67 suffered clinical relapse without retreatment (Group III) and 252 received retreatment (Group IV). The cumulative incidence of HBsAg loss at 8 years was 57.3% in Group I, 24.1% in Group II, 35.9% in Group III and 7.3% in Group IV. Cox regression analysis showed that nucleos(t)ide analogue experience, lower HBsAg levels at end-of-treatment (EOT) and higher HBsAg decline at 6 months after EOT were independently associated with HBsAg loss in Group I and Groups II+III. The rates of HBsAg loss at 6 years in patients with HBsAg decline >0.2 log IU/mL in Group I and HBsAg decline >0.15 log IU/mL in Group II+III at 6 months after EOT were 87.7% and 47.1%, respectively., Conclusion: The HBsAg loss rate was high and post-treatment HBsAg decline could predict high HBsAg loss rate among HBeAg-negative patients who discontinued entecavir or TDF and did not need retreatment., Competing Interests: Conflict of interest None declared., (Copyright © 2023 Editrice Gastroenterologica Italiana S.r.l.

Background/aims: To compare the rates of hepatitis B surface antigen (HBsAg) loss after discontinuation of entecavir versus tenofovir disoproxil fumarate (TDF) in patients with chronic hepatitis B (CHB) without cirrhosis., Methods: A total of 891 patients who received entecavir (n = 556) or TDF (n = 335) followed up post-treatment for at least 12 months were retrospectively assessed. A total of 677 patients who had continued entecavir or TDF therapy for at least 4 years were enrolled as the continued group., Results: Patients who discontinued TDF had higher rates of virological and clinical relapse and retreatment than patients who discontinued entecavir in both the HBeAg-positive and HBeAg-negative subgroups. In the entire discontinued cohort, the cumulative rates of HBsAg loss at 7 years were 22.6% and 35.4% in the entecavir and TDF groups respectively. Patients who discontinued TDF had significantly higher rates of HBsAg loss than patients who discontinued entecavir therapy in all (p = 0.019) and propensity score-matched (p = 0.015) patients, especially among the subgroups who achieved a sustained response (p < 0.001). Cox regression analysis revealed that TDF, longer treatment duration and lower HBsAg levels at end of treatment were independently associated with HBsAg loss in the entire discontinued group. The incidence of HBsAg loss was significantly higher in the discontinued group than in the continued group after propensity score matching (p < 0.001), including HBeAg-positive and HBeAg-negative patients., Conclusions: Patients who discontinued TDF had significantly higher rates of HBsAg loss than patients who discontinued entecavir, especially among the subgroups without HBV relapse after cessation of therapy., (© 2023 John Wiley & Sons Ltd.)

Introduction: Hepatitis B surface antigen (HBsAg) clearance leads to favorable outcomes in patients with chronic hepatitis B. HBsAg levels <200 IU/mL with HBsAg decline >0.5 log 10 IU/mL in 1 year have been reportedly predictive of HBsAg loss. This study aimed to use the REVEAL-hepatitis B virus cohort to validate and simplify this prediction rule and verify whether the simplified algorithm can be used among various clinical subgroups., Method: We analyzed 707 patients with untreated chronic hepatitis B who had 3 or more HBsAg measurements within 5 years before HBsAg seroclearance or last visit, greater than 1 year apart from one another. Rapid HBsAg decline was defined as HBsAg decline >0.5 log 10 IU/mL in 1 year or >1 log 10 IU/mL in 2 years. Sensitivity, specificity, positive predictive values, and negative predictive values were compared to assess the predictability of HBsAg seroclearance., Results: During a median follow-up of 10.7 years, 41 of the 707 patients cleared serum HBsAg. HBsAg levels at all measurements were lower ( P < 0.0001) and HBsAg decline was greater ( P < 0.0001) in patients with seroclearance compared with non-seroclearance patients. The predictive accuracy of predicting 1-year HBsAg loss using only the rapid decline algorithm (sensitivity = 0.4412, specificity = 0.9792, positive predictive value = 0.5172, negative predictive value = 0.972) was the same as the model combining rapid HBsAg decline and HBsAg levels <200 IU/mL. The simplified algorithm including only the rapid decline performed similarly among various levels of HBsAg, hepatitis B virus DNA, and alanine aminotransferase and was independent of inactive carrier state., Discussion: HBsAg decline >0.5 log 10 IU/mL/yr was a practical predictor of HBsAg seroclearance within 1 year in our community-based untreated cohort., (Copyright © 2023 The Author(s).

Background: Children under five are the vulnerable population most at risk of being infected with Plasmodium parasites, especially in the Sahel region. Seasonal malaria chemoprevention (SMC) recommended by World Health Organization (WHO), has proven to be a highly effective intervention to prevent malaria. Given more deaths reported during the COVID-19 pandemic than in previous years due to the disruptions to essential medical services, it is, therefore, necessary to seek a more coordinated and integrated approach to increasing the pace, coverage and resilience of SMC. Towards this end, fully leverage the resources of major players in the global fight against malaria, such as China could accelerate the SMC process in Africa., Methods: We searched PubMed, MEDLINE, Web of Science, and Embase for research articles and the Institutional Repository for Information Sharing of WHO for reports on SMC. We used gap analysis to investigate the challenges and gaps of SMC since COVID-19. Through the above methods to explore China's prospective contribution to SMC., Results: A total of 68 research articles and reports were found. Through gap analysis, we found that despite the delays in the SMC campaign, 11.8 million children received SMC in 2020. However, there remained some challenges: (1) a shortage of fully covered monthly courses; (2) lack of adherence to the second and third doses of amodiaquine; (3) four courses of SMC are not sufficient to cover the entire malaria transmission season in areas where the peak transmission lasts longer; (4) additional interventions are needed to consolidate SMC efforts. China was certified malaria-free by WHO in 2021, and its experience and expertise in malaria elimination can be shared with high-burden countries. With the potential to join the multilateral cooperation in SMC, including the supply of quality-assured health commodities, know-how transfer and experience sharing, China is expected to contribute to the ongoing scale-up of SMC., Conclusions: A combination of necessary preventive and curative activities may prove beneficial both for targeted populations and for health system strengthening in the long run. More actions are entailed to promote the partnership and China can be one of the main contributors with various roles., (© 2023. The Author(s).)

Our objective was to develop a predictive nomogram that could estimate the long-term survival of patients with very early/early-stage hepatocellular carcinoma (HCC) undergoing radiofrequency ablation (RFA). For this retrospective study, we enrolled 950 patients who initially received curative RFA for HCC at Barcelona Clinic Liver Cancer (BCLC) stages 0 and A between 2002 and 2016. Factors predicting poor survival after RFA were investigated through a Cox proportional hazard model. The nomogram was constructed using the investigated variables influencing overall survival (OS). After a median follow-up time of 6.25 years, 400 patients had died, and 17 patients had received liver transplantation. The 1-,3-,5-,7-, and 10-year OS rates were 94.5%, 73.5%, 57.9%, 45.7%, and 35.8%, respectively. Multivariate analysis showed that age greater than 65 years, albumin-bilirubin (ALBI) grades 2 and 3, AST-to-platelet ratio index (APRI) greater than 1, tumor size larger than 3 cm, diabetes mellitus, end-stage renal disease, and tumor number greater than 1 were significantly associated with poor OS. The nomogram was constructed using these seven variables. The validation results showed a good concordance index of 0.683. When comparing discriminative ability to tumor, node, and metastasis (TNM), BCLC, and Cancer of the Liver Italian Program (CLIP) staging systems, our nomogram had the highest C-index for predicting mortality. This nomogram provides useful information on prognosis post-RFA as a primary treatment and aids physicians in decision-making.

Background/aims: The incidence and relapse pattern in patients stopping tenofovir alafenamide (TAF), a prodrug of tenofovir which is more concentrated in hepatocytes, is unknown., Methods: HBeAg-negative CHB patients stopping tenofovir disoproxil fumarate (TDF) (off-TDF) or who had switched to TAF more than 3 months before discontinuation (off-TAF) were recruited. The propensity score-matching method (PSM) was used, creating a ratio of 1:3 between the off-TAF versus the off-TDF groups to adjust for associated factors., Results: After PSM, 180 off-TDF and 60 off-TAF patients were analyzed. The cumulative rates of virological and clinical relapse at 52 weeks were 75.1% and 58.5% respectively in the off-TDF group and 91.1% and 61.6% in the off-TAF group. Patients in the off-TAF group had significantly higher rates of virological relapse than those in the off-TDF group (p = 0.021), but not clinical relapse (p = 0.785). Multivariate cox regression analysis showed that off-TAF group was an independent factor for virological relapse, but not clinical relapse. Severity of clinical relapse and hepatic decompensation rate were comparable between off-TDF and off-TAF groups CONCLUSIONS: The off-TAF group had a higher virological relapse rate than the off-TDF group. The difference in clinical relapse pattern and severity was not clinically important between the two groups., Competing Interests: Conflict of interest Chien-Hung Chen, Wen-Juei Jeng, Tsung-Hui Hu, Yen-Chun Liu, Jing-Houng Wang, Chao-Hung Hung, Sheng-Nan Lu, Rong-Nan Chien declare that they have no conflict of interest., (Copyright © 2023 Editrice Gastroenterologica Italiana S.r.l.

Background & Aims: The influence of nonalcoholic fatty liver disease (NAFLD) on the long-term risk of cirrhosis and hepatocellular carcinoma (HCC) in Asian populations has not been widely investigated., Methods: We enrolled 129,374 adults aged 30 years and older, all of whom participated in a health screening program from 2008 through 2013, were seronegative for hepatitis B surface antigen and anti-hepatitis C virus antibodies, and had limited daily alcohol consumption (<20 g/d for men and <10 g/d for women). Abdominal ultrasonography was performed to determine the presence of NAFLD. The participants were divided into the following groups: NAFLD with increased or normal liver enzyme levels, and non-NAFLD with normal liver enzyme levels. The incidences of cirrhosis and HCC were determined through computerized data linkage with nationwide registries. Cox proportional hazard models were used to estimate the hazard ratios of NAFLD on the risks of cirrhosis and HCC., Results: The incidence rates of cirrhosis and HCC increased as follows: non-NAFLD with normal liver enzyme levels (n = 66,801; 51%), NAFLD with normal liver enzyme levels (n = 41,461; 32%), and NAFLD with increased liver enzyme levels (n = 21,112; 16%). In the NAFLD group with increased liver enzyme levels and the NAFLD group with normal liver enzyme levels, the corresponding multivariate-adjusted hazard ratios for cirrhosis were 3.51 (95% confidence interval [CI]: 2.36-5.22) and 0.73 (95% CI: 0.46-1.16), and for HCC were 1.91 (95% CI: 1.08-3.38) and 0.57 (95% CI: 0.31-1.04), respectively, compared with the non-NAFLD group (P for trend < .001). The findings were consistent after restricting the analysis to nonobese individuals (body mass index, <25 kg/m 2 ) and nonobese individuals without diabetes (P < .05)., Conclusions: Individuals with NAFLD and increased liver enzyme levels showed significantly higher risks for cirrhosis and HCC and should be monitored., (Copyright © 2023 AGA Institute.

During lactation, mammary epithelial cells (MECs) on the apical membrane are in contact with lactose in milk, while MECs on the basolateral membrane are in contact with glucose in blood. Both glucose and lactose are sweeteners that are sensed by a sweet taste receptor. Previously, we have shown that lactose exposure on the basolateral membrane, but not the apical membrane, inhibits casein production and phosphorylation of STAT5 in MECs. However, it remains unclear whether MECs have a sweet taste receptor. In this study, we confirmed that the sweet taste receptor subunit T1R3 existed in both the apical and basolateral membranes of MECs. Subsequently, we investigated the influence of apical and basolateral sucralose as a ligand for the sweet taste receptor using a cell culture model. In this model, upper and lower media were separated by the MEC layer with less-permeable tight junctions. The results showed in the absence of glucose, both apical and basolateral sucralose induced phosphorylation of STAT5, which is a positive transcriptional factor for milk production. In contrast, the T1R3 inhibitor basolateral lactisole reducing phosphorylated STAT5 and secreted caseins in the presence of glucose. Furthermore, exposure of the apical membrane to sucralose in the presence of glucose inhibited the phosphorylation of STAT5. Simultaneously, GLUT1 was partially translocated from the basolateral membrane to the cytoplasm in MECs. These results suggest that T1R3 functions as a sweet receptor and is closely involved in casein production in MECs., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Malaria and schistosomiasis are highly prevalent in Burkina Faso, whereas China has successfully eliminated malaria as well as schistosomiasis as a public health problem. To implement the China-Africa health cooperation initiative, a series of activities were launched since 2019 to enhance understanding and cooperation among malaria and schistosomiasis professionals in China and Burkina Faso. This study described the achievements of the First Virtual Symposium of China-Burkina Faso Cooperation on Schistosomiasis and Malaria Control. Pre- and post-test questionnaires were employed to study the knowledge changes of participants regarding malaria and schistosomiasis control and elimination, explore capacity-building priorities, and identify potential challenges. Chi-squared statistics were used to compare the differences between sub-groups, and p value < 0.05 was considered statistically significant. Participants ranked their preferences for challenges and capacity-building priorities in future cooperation. The responses of participants from both China and Burkina Faso indicated effective improvement in their general knowledge about the diseases whereas the improvement in professional knowledge on malaria and schistosomiasis was limited. The total correct response rate increased from 54.08% to 66.78%. Chinese participants had better schistosomiasis knowledge than Burkina Faso participants did, but the same result was not found for malaria. Diseases control strategies, surveillance and response system, and diagnostics techniques were identified as the top three priorities for future capacity building. Participants from China and Burkina Faso shared almost the same views about challenges except with respect to pathogens, which the former saw as a major challenge and the latter did not. The study findings will help policymakers, health managers, and researchers to understand the future cooperation between Burkina Faso and China on malaria and schistosomiasis., Competing Interests: Xiao-Nong Zhou is the Editor-in-Chief of Science in One Health, and Dramane Zongo is the Associate Editor of Science in One Health.

The feasibility and performance of predicting hepatocellular carcinoma (HCC) using a combined albumin-bilirubin (ALBI) and fibrosis-4 (FIB-4)-based model remain unclear in patients with compensated cirrhosis and chronic hepatitis B (CHB) receiving long-term nucleos(t)ide analog (NA) therapy. We enrolled 1158 NA-naïve patients with compensated cirrhosis and CHB treated with entecavir or tenofovir disoproxil fumarate. The patients' baseline characteristics, hepatic reserve, and fibrosis indices were analyzed. The combination of ALBI and FIB-4 was used to develop a prediction model of HCC. In this cohort, the cumulative incidence rates of HCC at 3, 5, and 10 years were 8.1%, 13.2%, and 24.1%, respectively. The combination of ALBI and FIB-4, Diabetes mellitus, and Alpha-fetoprotein (AFDA) were independent risk factors for HCC. The combined ALBI and FIB-4-based prediction model (i.e., AFDA) stratified the cumulative risk of HCC into three groups (with risk scores of 0, 1-3, 4-6) among all patients (P < 0.001). AFDA exhibited the highest area under the receiver operating characteristic (0.6812) for predicting HCC, which was higher than those of aMAP (0.6591), mPAGE-B (0.6465), CAMD (0.6379), and THRI (0.6356) and significantly higher than those of PAGE-B (0.6246), AASL-HCC (0.6242), and HCC-RESCUE (0.6242). Patients with a total score of 0 (n = 187, 16.1% of total patients) had the lowest cumulative HCC incidence of 3.4% at 5 years. The combined ALBI and FIB-4-based prediction model can stratify the risk of HCC in patients with compensated cirrhosis and CHB receiving NA therapy., Competing Interests: Cheng-Yuan Peng has served as an advisory committee member for AbbVie, Bristol-Myers Squibb, Gilead, and Roche., (AJCR Copyright © 2023.)

Background: The role of des-γ-carboxy prothrombin (DCP) in patients undergoing radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) needs to be clarified., Materials and Methods: 174 HCC patients that underwent RFA were enrolled. We calculated the HLs of DCP from the available values before and on first day after ablation and assessed the correlation between HLs of DCP and RFA efficacy., Results: Of 174 patients, 63 with pre-ablation DCP concentrations of ≥80 mAU/mL were analyzed. The ROC analysis showed the optimal cut-off value of HLs of DCP for predicting RFA response was 47.5 h. Therefore, we defined short HLs of DCP < 48 h as a predictor of favorable treatment response. Of 43 patients with a complete radiological response, 34 (79.1%) had short HLs of DCP. In 36 patients with short HLs of DCP, 34 (94.4%) had a complete radiologic response. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were 79.1%, 90.0%, 82.5%, 94.4%, and 66.7%. During the 12-month follow-up, patients who had short HLs of DCP had a better disease-free survival rate than patients with long HLs of DCP ( p < 0.001)., Conclusions: Short HLs of DCP < 48 h calculated on the first day post-RFA are a useful predictor for treatment response and recurrence-free survival after RFA.

Background: We aimed to compare the one-year retreatment efficacy and renal safety of entecavir, tenofovir disoproxil fumarate (TDF), and tenofovir alafenamide (TAF) after HBV relapse in patients who discontinued entecavir or TDF., Methods: This retrospective study included 289 chronic hepatitis B (CHB) patients without cirrhosis who received entecavir (n = 93), TDF (n = 103), or TAF (n = 86) retreatment for at least 12 months after entecavir or TDF cessation., Results: The rate of virological response (HBV DNA < 20 IU/mL) at 12 months of retreatment was 79/93 (84.9%) in the entecavir group, 92/103 (89.3%) in the TDF group, and 72/86 (83.7%) in the TAF group. The rate of ALT normalization (ALT ≤ 40 U/L) after 12 months of retreatment was 76/93 (81.7%) in the entecavir group, 77/103 (74.7%) in the TDF group , and 73/86 (84.9%) in the TAF group. There was no significant difference in the rates of virological response (p = 0.495) and ALT normalization (p = 0.198) among the three groups. Multivariate analysis showed that lower HBV DNA and HBsAg levels at baseline were independently associated with virological response at 12 months of retreatment. The TDF group (37.8 ± 34.8 U/L) had higher ALT levels at 12 months of retreatment than the TAF (27. ± 17.9 U/L, p = 0.015) and entecavir (28.3 ± 19.3 U/L, p = 0.022) groups. In patients with eGFR 60-90 mL/min/1.73 m 2 , eGFR change between baseline and 12 months of retreatment increased in the entecavir and TAF groups and decreased in the TDF group., Conclusions: TAF could be one of the retreatment options for retreatment of HBV relapse after entecavir or TDF cessation., (© 2022.

Background: For patients with chronic hepatitis B (CHB), the optimal stopping criteria for entecavir or tenofovir disoproxil fumarate treatment remain unclear., Methods: This study recruited CHB patients with levels of hepatitis B surface antigen (HBsAg) <100 IU/mL at the end of treatment (EOT) from Kaohsiung (n = 190) and Linkou (n = 188) Chang Gung Memorial Hospitals for use as development and validation groups, respectively., Results: In the development group, 108 patients with HBsAg ≤40 IU/mL were used for analysis of predictors of HBV relapse and HBsAg loss. Multivariate analysis showed that age, nucleos(t)ide analogue (NA)-experienced status, baseline hepatitis B core-related antigen (HBcrAg) and HBsAg at EOT were associated independently with virological and clinical relapse. An HBsAg level of 20 IU/mL at EOT was the best cut-off value for minimizing HBV relapse. Patients with EOT HBsAg ≤20 IU/mL had lower virological and clinical relapse rates and higher HBsAg loss rates than those with EOT HBsAg 21-40 IU/mL and HBsAg 41-100 IU/mL in the development and validation groups. The virological and clinical relapse rates were very low (5-year rates: 6.5% and 0%, respectively) and HBsAg loss rate was very high (5-year rate: 81.7%) in patients with a combination of baseline HBcrAg ≤4 log U/mL and EOT HBsAg ≤20 IU/mL in the development group., Conclusions: A combination of baseline HBcrAg ≤4 log U/mL and EOT HBsAg level ≤20 IU/mL might reduce the risk of HBV relapse and increase HBsAg loss rate, and might be helpful for off-NA follow-up strategy., (© The Author(s) 2022.

The findings regarding changes in renal function in patients with hepatitis C virus (HCV) infection treated with direct-acting antivirals (DAAs) are controversial. This study attempted to identify the factors associated with the large decline in renal function following DAA treatment. This retrospective cohort study included patients treated with DAAs at Chiayi and Yunlin Chang Gung Hospitals, Taiwan, from 1 January 2017 to 31 October 2020. Estimated glomerular filtration rate (eGFR) data were collected within 90 days prior to DAA therapy and 2 years after the confirmation of a sustained virologic response (SVR). We performed multiple logistic regression to evaluate the clinical or laboratory parameters associated with a large eGFR decline (≥10%). Among the enrolled 606 patients, the mean eGFR at the baseline and endpoint were 84.11 ± 24.38 and 78.88 ± 26.30 mL/min/1.73 m 2 , respectively ( p < 0.001). The factors associated with a large eGFR decline 2 years after the SVR included hypertension (OR: 1.481; 95% CI: 1.010-2.173, p = 0.044) and a higher baseline eGFR (OR: 1.016; 95% CI: 1.007-1.024, p < 0.001). A higher albumin level reduced the risk of a large eGFR decline (OR: 0.546; 95% CI: 0.342-0.872, p = 0.011). In the patients with HCV treated with DAAs, a larger renal function decline was more commonly observed in those with hypertension, a lower (but within normal range) albumin level, and a higher baseline eGFR, while DAA treatment had no effect. The clinical significance of these findings has to be further defined. Although some risk factors associated with chronic kidney disease may be alleviated after DAA treatment, the regular control and follow-up of risk factors and renal function are still recommended in at-risk patients after HCV eradication.

Background: Mass screening and treatment (MSAT) for malaria elimination lacks an ideal diagnostic tool to allow sensitive and affordable test of the target population in the field. This study evaluated whether Capture and Ligation Probe-PCR (CLIP-PCR) could be used in a field MSAT in Laiza City, Myanmar., Methods: On day 0, two dried blood spots were collected from each participant. On day 1, all samples were screened for Plasmodium in a 20 m 2 laboratory with workbench, a biosafety cabinet, a refrigerator, a benchtop shaking incubator and a qPCR machine, by four technicians using CLIP-PCR with sample pooling, at a health clinic of the Chinese bordering town of Nabang. On day 2, all positives were followed up and treated., Results: Of 15,038 persons (65% of the total population) screened, 204 (1.36%) were CLIP-PCR positives. Among them, 188, 14, and 2 were infected with Plasmodium vivax, Plasmodium falciparum, and P. vivax/P. falciparum mix, respectively. The testing capacity was 538 persons/day, with a cost of US$0.92 /person. The proportion of submicroscopic infection was 64.7%. All positive individuals received treatment within 72 h after blood collection., Conclusion: Using CLIP-PCR in MSAT in low transmission settings can support the malaria elimination efforts in the China-Myanmar border region., (© 2023.

Purpose: Barcelona Clinic Liver Cancer (BCLC) guidelines designate monofocal hepatocellular carcinoma (HCC) > 2 cm as BCLC A, and large monofocal HCC is defined at > 5 cm. We aimed to evaluate the optimal cutoff value for large monofocal HCC based on prognosis stratification., Methods: From 2011 to 2018, 3055 patients with newly diagnosed HCC, who were managed in our institution, including 868 patients with monofocal HCC > 2 cm and 330 patients with BCLC B, were enrolled in this retrospective study., Results: Monofocal HCC > 5 cm patients had worse overall survival (OS) than monofocal HCC 2-5 cm patients (5-year OS: 54% vs. 57%; p = 0.047), confirmed by multivariate analysis (hazard ratio (HR): 1.492, 95% confidence interval (CI): 1.055-2.110; p = 0.024). Monofocal HCC > 5 cm patients had better OS than BCLC B HCC patients (5-year OS: 54% vs. 25%; p < 0.001), confirmed by multivariate analysis (HR: 0.670, 95% CI: 0.481-0.934; p = 0.018). Using 7 cm as the monofocal HCC cutoff value resulted in worse OS than monofocal HCC 2-7 cm (5-year OS: 50% vs. 57%; p = 0.02), confirmed by multivariate analysis (HR: 1.625, 95% CI: 1.039-2.540; p = 0.033). Monofocal HCC > 7 cm patients had better OS than BCLC B patients (p = 0.006). However, no significant difference was identified in the multivariate analysis (HR: 0.726; 95% CI: 0.473-1.115; p = 0.144)., Conclusions: The prognosis of monofocal HCC > 7 cm was similar to that of BCLC B, indicating that 7 cm represents an optimal cutoff value for prognosis stratification in large monofocal HCC., (© 2023.

Hepatocellular carcinoma (HCC) is a major cause of cancer death in Taiwan, and in the past 30-40 years, Taiwan has been committed to its prevention and treatment. We aimed to investigate the secular trends of characteristics and the survival of HCC in recent decades after making increased efforts. Between 2011 and 2019, a total of 73,817 cases were enrolled from the TCR database. The overall male-to-female ratio was 7/3. The overall, male and female mean ages increased from 63.8 to 66.1 years, 62.0 to 64.3 years and 68.3 to 70.4 years, respectively. After dividing by viral etiologies and gender, the mean age showed increasing trends in all subgroups. The proportions of HBV-HCC, HCV-HCC, HBV+HCV-HCC and Non-HBV+non-HCV-HCC were 48.3%, 25.2%, 5.3% and 21.3% in males, compared with 25.5%, 48.6%, 5.3% and 20.5% in females, respectively. The 5-year survival rates of BCLC stages 0, A, B, C and D were 70%, 58%, 34%, 11% and 4%, respectively. The proportion of BCLC stage 0 increased from 6.2% to 11.3%. Multivariate analysis showed that being female, older age, diagnostic year, BCLC stages, hospital level, body mass index, smoking, alcohol consumption, AFP, Child-Pugh classification and HBV/HCV status were independent predictors for survival. In recent decades, the overall survival of HCC in Taiwan has been improving and might be partly associated with increased BCLC 0 and Child-Pugh A patients, while with the consequent age of patients increasing over time. The proportion of viral-related HCC is decreasing, while nonviral-related HCC is increasing.

Mac-2 binding protein glycosylation isomer (M2BPGi) has not been used in a risk score to predict hepatocellular carcinoma (HCC). We enrolled 1003 patients with chronic hepatitis B and cirrhosis receiving entecavir or tenofovir therapy for more than12 months to construct an HCC risk score. In the development cohort, Cox regression analysis identified male gender, age, platelet count, AFP and M2BPGi levels at 12 months of treatment as independent risk factors of HCC. We developed the HCC risk prediction model, the ASPAM-B score, based on age, sex, platelet count, AFP and M2BPGi levels at 12 months of treatment, with the total scores ranging from 0 to 11.5. This risk model accurately classified patients into low (0−3.5), medium (4−7), and high (>7) risk in the development and validation groups (p < 0.001). The areas under the receiver operating characteristic curve (AUROC) of 3-, 5- and 9-year risks of HCC were 0.742, 0.728 and 0.719, respectively, in the development cohort. All AUROC between the ASPAM-B and APA-B, PAGE-B, RWS-HCC and THRI scores at 3−9 years were significantly different. The M2BPGi-based risk model exhibited good discriminant function in predicting HCC in cirrhotic patients who received long-term antiviral treatment.

Background: Snail control is critical to schistosomiasis control efforts in China. However, re-emergence of Oncomelania hupensis is challenging the achievements of schistosomiasis control. The present study aimed to test whether the amphibious snails can spread across watersheds using a combination of population genetics and geographic statistics., Methods: The digital maps and attributes of snail habitats were obtained from the national survey on O. hupensis. Snail sampling was performed in 45 counties of Sichuan Province. The cox1 gene of specimens was characterized by sequencing. Unique haplotypes were found for phylogenetic inference and mapped in a geographical information system (GIS). Barriers of gene flow were identified by Monmonier's maximum difference algorithm. The watercourses and watersheds in the study area were determined based on a digital elevation model (DEM). Plain areas were defined by a threshold of slope. The slope of snail habitats was characterized and the nearest distance to watercourses was calculated using a GIS platform. Spatial dynamics of high-density distributions were observed by density analysis of snail habitats., Results: A total of 422 cox1 sequences of O. hupensis specimens from 45 sampling sites were obtained and collapsed into 128 unique haplotypes or 10 clades. Higher haplotype diversity in the north of the study area was observed. Four barriers to gene flow, leading to five sub-regions, were found across the study area. Four sub-regions ran across major watersheds, while high-density distributions were confined within watersheds. The result indicated that snails were able to disperse across low-density areas. A total of 63.48% habitats or 43.29% accumulated infested areas were distributed in the plain areas where the overall slope was < 0.94°. Approximately 90% of snail habitats were closer to smaller watercourses. Historically, high-density areas were mainly located in the plains, but now more were distributed in hilly region., Conclusions: Our study showed the cross-watershed distribution of Oncomelania snails at a large scale. Natural cross-watershed spread in plains and long-distance dispersal by humans and animals might be the main driver of the observed patterns. We recommend cross-watershed joint control strategies for snail and schistosomiasis control., (© 2022. The Author(s).)

Background: To evaluate the protective efficacy of a hepatitis B (HB) vaccination program in Taiwan among high-risk children., Methods: Children born to HBeAg-positive mothers from 2001 to 2010 were invited back. Blood samples for hepatitis B virus (HBV) seromarkers were taken and the children underwent hepatobiliary ultrasonography. Perinatal factors including delivery mode and vaccination history were collected from their medical records. According to the results of HBV serological markers, the children were initially classified into five groups: HBV naïve, HB vaccine responder, HBsAg carrier, recovered from HBV infection, and anti-HBc-positive alone. Children in the HBV naïve and anti-HBc-positive alone groups who presented with an anamnestic response after a booster HB vaccine were re-assigned to the vaccine responder and recovered from infection groups, respectively., Results: All of the 196 enrolled children received postnatal hepatitis B immunoglobulin (HBIG) and HB vaccinations, of whom one was HBV naïve (0.5%), 109 were vaccine responders (55.6%), 21 were carriers (10.7%), and 65 recovered from infection (33.2%). Among the 21 carriers, 14 (66.7%) presented in the immunotolerant phase. Cesarean section was the only significant perinatal factor between the carriers (5.3%) and those who recovered from infection (37.7%) (p = 0.007)., Conclusion: In this study, there was a 43.9% HBV infection rate and 10.7% HBsAg carrier rate in high-risk Taiwanese children even after receiving HBIG and HB vaccinations. C-section may protect newborns from becoming HBsAg carriers, while HBV genotype and time of HBIG injection did not contribute to the HBV carrier rate., Competing Interests: Conflicts of interest All authors have no conflicts of interest that could be perceived to bias their work, making known all financial support and any other personal connections., (Copyright © 2021 Chang Gung University.

Background/purpose: Controversies over the use of alpha-fetoprotein (AFP) for detection of hepatocellular carcinoma (HCC) existed from guidelines. Using large-scale database and hospital-based information, we aimed to reappraise the role of AFP in HCC surveillance, including proportion of AFP elevation by stage of HCC, additional benefit of AFP in combination of ultrasonography (US) in the detection of early HCC, and survival in early HCC with high AFP levels., Methods: This retrospective study enrolled 43,437 patients from database of the Taiwan Cancer Registry (TCR) and 4250 patients from Kaohsiung Chang Gung Memorial Hospital (KCGMH) between January 2011 and December 2017., Results: The HCC cases in KCGMH accounted for 9.8% of the total cases in the TCR. Among both nationwide database and hospital-based information, the proportion of early HCC patients with an AFP level of ≥20 ng/mL was approximately 40%. In KCGMH, the proportion of patients with an AFP level of ≥20 ng/mL and a virus-related (hepatitis B and C) etiology was around 41.7%; furthermore, among patients with early HCC, those with an AFP level of ≥20 ng/mL had 4.7 years of median survival and 48.3% of the 5-year overall survival rate. By hospital electronic medical records review of early HCC cohort in KCGMH, approximately 10.9% of patients with AFP levels ≥20 ng/mL had US-undetectable early HCC., Conclusion: This study suggested that AFP in combination with US would add an additional benefit as being a prompted role for detection of early HCC in patients with US-undetectable HCC., Competing Interests: Declaration of competing interest The authors have no conflicts of interest relevant to this article., (Copyright © 2022 Formosan Medical Association.

A straightforward strategy for the metal-free construction of trifluoromethyl-containing pyrazole derivatives has been achieved from readily available α-halo hydrazones and CF 3 -imidoyl sulfoxonium ylides. The cascade transformation proceeds through the formal [4+1] cycloaddition followed by an unexpected dual double bond isomerization. The protocol features mild conditions, easy operation, excellent substrate compatibility, and good regioselectivity. The synthetic utility is demonstrated by scale-up reaction and further elaboration of the obtained pyrazole products.

Background: Hyperendemic townships of hepatitis C virus (HCV) infection should devote extra efforts to eliminate HCV. We aimed to evaluate efficacy of the screening and linkage to care in two HCV hyperendemic townships., Methods: Village-to-village HCV screening using anti-HCV reflex HCV Ag test was conducted in two HCV hyperendemic rural townships (Lioujiao and Yijhu). All residents aged 30 years or older were invited. Those patients detected as infected were referred to nearby hospitals or clinics in Lioujiao and to an accessible outreach hepatology clinic in Yijhu., Results: The populations of Lioujiao and Yijhu townships at time of survey were 18,389 and 14,787 with 6086 (33.1%) and 4604 (31.1%) having ever been previously screened, and 1517 and 1071 responded to this screening respectively. Their crude screening coverage rates were 41.5% and 38.5%, and adjusted screening coverage rates were 54.3% and 94.6% respectively. The prevalence rates of anti-HCV and HCV Ag were 17.9% and 11.9% in Lioujiao, and 9.2% and 5.6% in Yijhu respectively, with their rates of antigenemia (HCV Ag/anti-HCV) being 62.1% and 60.6% respectively. Numbers needed to test (NNT) to find a candidate for anti-viral treatment were 9 and 18. For linkage to care, treatment rate by referral (Lioujiao) was slightly lower than by accessible outreach hepatology clinic (Yijhu) (84.9% vs. 93.3%, p = 0.093). Overall successful sustained virological response rate at week 12 was 98.2% (161/164) in outreach hepatology clinic., Conclusion: Since NNT was low, it was worthwhile conducting intensive screening in these hyperendemic townships. For high treatment rate, accessible outreach hepatology clinic is feasible especially in areas without adequate medical resources., Competing Interests: Declaration of competing interest The authors have no conflicts of interest relevant to this article., (Copyright © 2022 Formosan Medical Association.

Real-world data on the effectiveness of glecaprevir/pibrentasvir (GLE/PIB) for patients with HCV infection and compensated cirrhosis is limited, especially for the 8-week regimen and in an Asian population. This retrospective study enrolled 159 consecutive patients with HCV and compensated cirrhosis who were treated with GLE/PIB at a single center in Taiwan. Sustained virological response (SVR) and adverse events (AEs) were evaluated. Among the 159 patients, 91 and 68 were treated with GLE/PIB for 8 and 12 weeks, respectively. In the per protocol analysis, both the 8- and 12-week groups achieved 100% SVR (87/87 vs. 64/64); and in the evaluable population analysis, 95.6% (87/91) of the 8-week group and 94.1% (64/68) of the 12-week group achieved SVR. The most commonly reported AEs, which included pruritus (15.4% vs. 26.5%), abdominal discomfort (9.9% vs. 5.9%), and skin rash (5.5% vs. 5.9%), were mild for the 8- and 12-week groups. Two patients in the 8-week group exhibited total bilirubin elevation over three times the upper normal limit. One of these two patients discontinued GLE/PIB treatment after 2 weeks but still achieved SVR. Both 8- and 12-week GLE/PIB treatments are safe and effective for patients of Taiwanese ethnicity with HCV and compensated cirrhosis., Competing Interests: The authors have declared that no competing interests exist.

Without analyzing the status of viremia, hepatitis C virus-related hepatocellular carcinoma (HCV-HCC) patients are proposed to have better prognosis than hepatitis B virus-related HCC (HBV-HCC) patients using sorafenib. We aimed to elucidate the efficacy of concurrent sorafenib and anti-viral treatment for HCC patients with HBV or HCV infection in real world. Between January 2018 and January 2021, 256 unresectable HCC patients receiving first-line sorafenib were evaluated. High-potency nucleoside analogs were used for HBV control, whereas direct-acting antivirals were administered for HCV eradication. Well-controlled viremia was defined as patients who had undetectable viremia, or who had been receiving antivirals at least 6 months before sorafenib. We recruited 116 (65.2%) HBV-HCC patients and 62 (34.8%) HCV-HCC patients. Using sorafenib, progression-free survival and overall survival (OS) rates between these two groups were not different. Before sorafenib, 56% of HBV-HCC patients and 54.8% of HCV-HCC patients had well-controlled viremia and their OS was superior to those who had uncontrolled viremia (15.5 vs. 11.1 months, p = 0.001). Dividing our patients into four subgroups as well-controlled HCV viremia, well-controlled HBV viremia, uncontrolled HCV viremia, and uncontrolled HBV viremia, their OS rates were distributed with a significantly decreasing trend as 21.9 months, 15.0 months, 14.2 months, and 5.7 months ( p = 0.009). Furthermore, well-controlled viremia was associated with mortality in multivariate analysis (Hazard ratio: 0.63, 95% confidence interval: 0.42-0.93, p = 0.022). In real-life, HBV or HCV infection did not contribute to the prognosis of HCC patients receiving sorafenib; however, whether viremia was controlled or not did contribute.
