Abstract
Metastatic cancer is a leading cause of death in cancer patients worldwide. While circulating hybrid cells (CHCs) are implicated in metastatic spread, studies documenting their tissue origin remain sparse, with limited candidate approaches using one-two markers. Utilizing high-throughput single-cell and spatial transcriptomics, we identified tumor hybrid cells (THCs) co-expressing epithelial and macrophage markers and expressing a distinct transcriptome. Rarely, normal tissue showed these cells (NHCs), but their transcriptome was easily distinguishable from THCs. THCs with unique transcriptomes were observed in breast and colon cancers, suggesting this to be a generalizable phenomenon across cancer types. This study establishes a framework for HC identification in large datasets, providing compelling evidence for their tissue residence and offering comprehensive transcriptomic characterization. Furthermore, it sheds light on their differential function and identifies pathways that could explain their newly acquired invasive capabilities. THCs should be considered as potential therapeutic targets.

Abstract
Insects are covered with free neutral cuticular hydrocarbons (CHC) that may be linear, branched, and unsaturated and vary in their chain length. The CHC composition is species-specific and contributes to the adaptation of the animal to its ecological niche. Commonly, CHCs contribute substantially to the inward and outward barrier function of the cuticle and serve pheromonal communication. They are generally determined by gas-chromatography, a time-consuming method requiring detailed expertize, but it is not available in many laboratories. Here, we report on the establishment of a colorimetric method allowing semi-quantitative determination of unsaturated CHCs in Drosophila flies. This method is based on the in vitro reaction of vanillin with double bounds in lipid molecules in an acidic solution to generate a reddish color. We found a robust correlation between gas chromatographic and vanillin-colorimetric data on unsaturated CHCs amounts in single flies. As the role of unsaturated CHCs in the performance of insects in their environment is only partly understood, we think that this novel method would allow fast and broad analyses of this type of CHCs in insects both in the field and in laboratories and thereby contribute to a substantial improvement in the investigation of this matter.

Abstract
This article focuses on the development of algorithms for a smart neurorehabilitation system, whose core is made up of artificial neural networks. The authors of the article have proposed a completely unique transfer of ACE-R results to the CHC model. This unique approach allows for the saturation of the CHC model domains according to modified ACE-R factor analysis. The outputs of the proposed algorithm thus enable the automatic creation of a personalized and optimized neurorehabilitation plan for individual patients to train their cognitive functions. A set of tasks in 6 levels of difficulty (level 1 to level 6) was designed for each of the nine CHC model domains. For each patient, the results of the ACE-R screening helped deter-mine the specific CHC domains to be rehabilitated, as well as the initial gaming level for rehabilitation in each domain. The proposed artificial neural network algorithm was adapted to real data from 703 patients. Experimental outputs were compared to the outputs of the initially designed fuzzy expert system, which was trained on the same real data, and all outputs from both systems were statistically evaluated against expert conclusions that were available. It is evident from the conducted experimental study that the smart neurorehabilitation system using artificial neural networks achieved significantly better results than the neurorehabilitation system whose core is a fuzzy expert system. Both algorithms are implemented into a comprehensive neurorehabilitation portal (Eddie), which was supported by a research project from the Technology Agency of the Czech Republic.

Abstract
Background When parents die from HIV/AIDS-related causes, children often experience emotional instability and are given additional obligations, such as caring for siblings. Youths may react in a variety of ways, including increasing alcohol consumption, and their relationships with their siblings may be altered positively or negatively. Aim The purpose of this article is to examine the lived experiences of youths in managing themselves after losing a family member to HIV/AIDS and suggest developed guidelines for nurses to advise youths on self-management after losing a family member to HIV/AIDS. Setting Khayelitsha, Western Cape province, South Africa. Method A descriptive phenomenological design for this study was followed. The researcher conducted 11 semi-structured interviews with participants. The study was conducted with participants that were youth aged between 18 and 25 years. Results The study revealed that the death of a family provider can be difficult for the youth left behind to deal with the changes in their daily lives. Conclusion The findings demonstrated that the death of a family member has a significant impact on the family. One of the more senior family members must assume charge and remain strong to help their siblings focus on the future. The death of a family member might result in a cascade of forced changes that necessitate new behaviours to maintain stability. Contribution This study's context-based data focuses on how the Community Health Centre (CHC) may assist young people in managing themselves after a family provider has died from HIV/AIDS, using the developed guidelines.

Abstract
BACKGROUND The growing culture of substance use among people living with human immunodeficiency virus (PLWH) is a serious threat to the human immunodeficiency virus (HIV) pandemic. As the gatekeepers of comprehensive care, primary care providers are responsible for screening, assessing, and managing individuals who use substances. AIM This study aimed to evaluate primary care providers' views and approaches to substance use management among PLWH who attend primary care services in Mthatha. SETTING This study was conducted at Ngangelizwe and Mbekweni Community Health Centres (CHCs) in the Eastern Cape province's King Sabata Dalindyebo (KSD) sub-district municipality. METHODS This qualitative phenomenological study involved the views of primary care providers. This study included 32 primary health care (PHC) providers. All participants were female except one male with a mean age of 48.6 years (range 27-64 years). Semi-structured interviews were conducted until saturation of the theme was reached. Then, the data from the transcribed interview were analysed with a thematic framework. RESULTS Substance use among PLWH was reported to be associated with poor clinical outcomes and disruption of antiretroviral therapy (ART) adherence. The significant barriers reported for substance use management in PHC settings were a lack of resources, skilled providers and poor community participation. CONCLUSION Substance use management programmes are not commonly offered in PHC because of the lack of human and infrastructural resources, the lack of skilled providers and poor community engagement.Contribution: This study provides a context-specific PHC providers' approach to substance use management.

Abstract
BACKGROUND & AIMS Diabetes mellitus (DM) is known to increase the risk of hepatocellular carcinoma (HCC) among individuals with chronic hepatitis C (CHC). We aimed to evaluate whether metformin reduces HCC risk among individuals with DM and CHC after successful antiviral therapy. METHODS Individuals with CHC who achieved a sustained virological response (SVR) after interferon-based therapy were enrolled in a large-scale, multicenter cohort in Taiwan (T-COACH). Cases of HCC at least 1 year after SVR were identified through linkage to the catastrophic illness and cancer registry databases. RESULTS Of 7,249 individuals with CHC enrolled in the study, 781 (10.8%) had diabetes and 647 (82.8%) were metformin users. During a median follow-up of 4.4 years, 227 patients developed new-onset HCC. The 5-year cumulative HCC incidence was 10.9% in non-metformin users and 2.6% in metformin users, compared to 3.0% in individuals without DM (adjusted hazard ratio [aHR] 2.83; 95% CI 1.57-5.08 and aHR 1.46; 95% CI 0.98-2.19, respectively). Cirrhosis was the most important factor significantly associated with higher HCC risk in Cox regression analysis, followed by DM non-metformin use, older age, male sex, and obesity; whereas hyperlipidemia with statin use was associated with a lower HCC risk. Using the two most crucial risk factors, cirrhosis and DM non-metformin use, we constructed a simple risk model that could predict HCC risk among individuals with CHC after SVR. Metformin use was shown to reduce the risk of all liver-related complications. CONCLUSIONS Metformin use greatly reduced HCC risk after successful antiviral therapy in individuals with diabetes and CHC. A simple risk stratification model comprising cirrhosis and DM non-metformin use could predict long-term outcomes in individuals with CHC after SVR. IMPACT AND IMPLICATIONS The current study provides evidence that metformin could reduce hepatocellular carcinoma (HCC) incidence after successful antiviral therapy among those with diabetes and chronic hepatitis C in a large-scale nationwide cohort study. Although successful antiviral therapy greatly reduces HCC risk in individuals with chronic hepatitis C, those with cirrhosis, diabetes, obesity, and the elderly remain at high risk of HCC development. We demonstrated that a simple risk model composed of two crucial unfavorable factors, cirrhosis and diabetes without metformin use, predicts the risk of HCC and major liver-related complications after successful antiviral therapy in individuals with chronic hepatitis C. Metformin use is highly recommended for individuals with diabetes and chronic hepatitis C after viral eradication to reduce the risk of HCC.

Abstract
For over a century, the structure of intelligence has been dominated by factor analytic methods that presume tests are indicators of latent entities (e.g., general intelligence or g). Recently, psychometric network methods and theories (e.g., process overlap theory; dynamic mutualism) have provided alternatives to g-centric factor models. However, few studies have investigated contemporary cognitive measures using network methods. We apply a Gaussian graphical network model to the age 9-19 standardization sample of the Woodcock-Johnson Tests of Cognitive Ability-Fourth Edition. Results support the primary broad abilities from the Cattell-Horn-Carroll (CHC) theory and suggest that the working memory-attentional control complex may be central to understanding a CHC network model of intelligence. Supplementary multidimensional scaling analyses indicate the existence of possible higher-order dimensions (PPIK; triadic theory; System I-II cognitive processing) as well as separate learning and retrieval aspects of long-term memory. Overall, the network approach offers a viable alternative to factor models with a g-centric bias (i.e., bifactor models) that have led to erroneous conclusions regarding the utility of broad CHC scores in test interpretation beyond the full-scale IQ, g.

Abstract
BACKGROUND There is an obvious need to diagnose hepatocellular carcinoma using novel non-invasive and sensitive biomarkers. Circular RNAs have recently attracted great interest as promising biomarkers and treatment targets. However, their function in hepatocellular carcinoma whose etiology related to hepatitis C has been rarely studied. AIM OF WORK The current study was conducted to analyze differential expression of circ-ITCH in plasma of Egyptian HCC patients with concomitant HCV infection, compared to normal control subjects, to investigate its correlation with liver function parameters, and to determine the possible diagnostic ability of circ-ITCH in plasma as a non-invasive marker, compared to its linear counterpart. RESULTS The results showed that the relative expression of circ-ITCH was significantly higher in the plasma of HCC patients (P<0.05). Moreover, when comparing its expression in the metastatic and non-metastatic subgroups, it was significantly higher in the non-metastatic HCC group compared to control group (P<0.05). Circ-ITCH was positively correlated with liver enzymes AST, ALT (P<0.001), also was significantly higher in HCC child C patients. To evaluate the potential diagnostic value of circ-ITCH in plasma, a ROC curve was generated, the AUC was 0.661, (95% CI: 0.5433-0.778) with a sensitivity and specificity 65% and 70% respectively. CONCLUSION The results revealed that circ-ITCH is-with no doubt-involved in the pathogenesis of HCC and its high level may be related to HCV infection, further researches in this area will certainly make great contributions in understanding. In conclusion our results suggested that circ-ITCH may be used as a noninvasive diagnostic marker and a promising therapeutic target for HCC.

Abstract
OBJECTIVE The aim of this study was to investigate the relationship between symptomatology and the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-IV) cognitive profiles in Attention Deficit and Hyperactivity Disorder (ADHD), taking into account clinical heterogeneity. METHOD The WISC-IV was administered to 60 children aged 6 to 13 years with ADHD who had not previously taken psychotropic medication. Conners Teacher-Rating Scale (CTRS-R/L) and Conners Parent-Rating Scale (CPRS-R/L) were completed by parents and teachers. RESULTS We found a statistically significant positive correlation between the symptoms of hyperactivity/impulsivity and PSI (Processing Speed Index). A statistically significant negative correlation was found between the CTRS-R/L's DSM-IV Inattentive subscale and PRI (Perceptual Reasoning Index). No relationship was found between the inattention or hyperactivity/impulsivity symptomatology with Working Memory Index (WMI). WMI stood out as the most frequently reported weakness among the four index scores. CONCLUSION Considering the relationship between the cognitive domains of RDoC (Research Domain Criteria) and dimensions of HiTOP with the ADHD symptom clusters, the assessment of cognitive and behavioral symptoms may be useful for phenotyping ADHD. According to the CHC (Cattell-Horn-Carroll) theory; the positive correlation level between PSI, which is accepted as Gs, and hyperactivity/impulsivity symptoms in people with ADHD may be due to the fact that hyperactivity is one of the narrow cognitive domains of Gps.

Abstract
We have recently demonstrated the ability of a simple predictive model (GES) score to determine the risk of hepatocellular carcinoma (HCC) after using direct-acting antivirals. However, our results were restricted to Egyptian patients with hepatitis C virus (HCV) genotype 4. Therefore, we studied a large, independent cohort of multiethnic populations through our international collaborative activity. Depending on their GES scores, patients are stratified into low risk (≤ 6/12.5), intermediate risk (> 6-7.5/12.5), and high risk (> 7.5/12.5) for HCC. A total of 12,038 patients with chronic HCV were analyzed in this study, of whom 11,202 were recruited from 54 centers in France, Japan, India, the U.S., and Spain, and the remaining 836 were selected from the Gilead-sponsored randomized controlled trial conducted across the U.S., Europe, Canada, and Australia. Descriptive statistics and log-rank tests. The performance of the GES score was evaluated using Harrell's C-index (HCI). The GES score proved successful at stratifying all patients into 3 risk groups, namely low-risk, intermediate-risk, and high-risk. It also displayed significant predictive value for HCC development in all participants (p < .0001), with HCI ranging from 0.55 to 0.76 among all cohorts after adjusting for HCV genotypes and patient ethnicities. The GES score can be used to stratify HCV patients into 3 categories of risk for HCC, namely low-risk, intermediate-risk, and high-risk, irrespective of their ethnicities or HCV genotypes. This international multicenter validation may allow the use of GES score in individualized HCC risk-based surveillance programs.

Abstract
Background and Aims: Whether hepatitis C virus (HCV) reactivation occurs and how the viral load evolves in anti-HCV antibody-positive chronic hepatitis B (CHB) patients who underwent nucleos(t)ide analogue (Nuc) therapies remain unsolved. Methods: A cohort of 66 such patients was studied. Results: At the start of Nuc treatment (baseline), all patients had detectable hepatitis B virus (HBV) DNA levels (6.05 ± 1.88 log IU/mL), while HCV RNA levels (3.79 ± 1.43 log IU/mL) were detected (i.e., chronic hepatitis C (CHC)) in only 13 patients (19.7%). Following Nuc therapies, HBV DNA levels reached the nadirs at end of therapy (EOT) (6.05 ± 1.88 vs. 0.25 ± 0.99 log IU/mL, p < 0.0001) and relapsed at 6 months after EOT (6mEOT) at a level of 3.45 ± 2.64 log IU/mL compared with EOT (p < 0.0001). Among the 13 CHC patients, a non-significant decrease in HCV RNA was noted at EOT (3.52 ± 1.71 vs. 2.77 ± 2.63 log IU/mL, p = 0.166) but tended to decrease further at 6mEOT (2.77 ± 2.63 vs. 1.89 ± 2.06 log IU/mL, p = 0.063). Two of the thirteen CHC patients showed an increase in HCV-RNA ≥ 1 log10 IU/mL at EOT, and one of the fifty-three patients with undetectable HCV RNA at baseline (i.e., resolved past HCV infection) showed detectable HCV RNA at year 1 (3200 IU/mL) and year 2 (1240 IU/mL) following entecavir therapy. Conclusions: HCV reactivation did occur during HBV suppression, and the rate was 4.5% (3/66), 15.4% (2/13), and 1.9% (1/53), for all patients, CHC patients, and patients with resolved past HCV infection, respectively. The reverse HBV and HCV viral evolutions at 6mEOT indicate that HBV relapse may suppress HCV replication again.

Abstract
OBJECTIVE To compare Oregon school-based health centers (SBHCs) with community health centers (CHCs) as sources of adolescent contraceptive services. DATA SOURCES Oregon electronic health record data, 2012-2016. STUDY DESIGN We compared clinic-level counseling rates and long-acting reversible contraception (LARC) provision, adolescent populations served, and visit-level LARC provision time trends. We evaluated adjusted associations between LARC provision and Title X participation by clinic type. DATA COLLECTION/EXTRACTION METHODS We used diagnosis and procedure codes to identify contraceptive counseling and provision visits, excluding visits for adolescents not at risk of pregnancy. PRINCIPAL FINDINGS CHCs were more likely to provide LARC on-site than SBHCs (67.2% vs. 36.4%, respectively). LARC provision increased more at SBHCs (5.8-fold) than CHCs (2-fold) over time. SBHCs provided more counseling visits per clinic (255 vs. 142) and served more young and non-White adolescents than CHCs. The adjusted probability of LARC provision at Title X SBHCs was higher than non-Title X SBHCs (4.4% [3.9-4.9] vs. 1.7% [1.4-2.0]), but there was no significant association at CHCs. CONCLUSIONS In Oregon, CHCs and SBHCs are both important sources of adolescent contraceptive services, and Title X plays a crucial role in SBHCs. Compared with CHCs, SBHCs provided more counseling, showed a larger increase in LARC provision over time, and served more younger and non-White adolescents.

Abstract
BACKGROUND AND AIM Many HCC risk prediction scores were developed to guide HCC risk stratification and identify CHC patients who either need intensified surveillance or may not require screening. There is a need to compare different scores and their predictive performance in clinical practice. We aim to compare the newest HCC risk scores evaluating their discriminative ability, and clinical utility in a large cohort of CHC patients. PATIENTS AND METHODS The performance of the scores was evaluated in 3075 CHC patients who achieved SVR following DAAs using Log rank, Harrell's c statistic, also tested for HCC-risk stratification and negative predictive values. RESULTS HCC developed in 212 patients within 5 years follow-up. Twelve HCC risk scores were identified and displayed significant Log rank (p ≤ 0.05) except Alonso-Lopez TE-HCC, and Chun scores (p = 0.374, p = 0.053, respectively). Analysis of the remaining ten scores revealed that ADRES, GES pre-post treatment, GES algorithm and Watanabe (post-treatment) scores including dynamics of AFP, were clinically applicable and demonstrated good statistical performance; Log rank analysis < 0.001, Harrell's C statistic (0.66-0.83) and high negative predictive values (94.38-97.65%). In these three scores, the 5 years cumulative IR in low risk groups be very low (0.54-1.6), so screening could be avoided safely in these patients. CONCLUSION ADRES, GES (pre- and post-treatment), GES algorithm and Watanabe (post-treatment) scores seem to offer acceptable HCC-risk predictability and clinical utility in CHC patients. The dynamics of AFP as a component of these scores may explain their high performance when compared to other scores.

Abstract
BACKGROUND AND AIMS With the growing number of treated hepatitis C patients, the current 'one-size-fits-all' hepatocellular carcinoma (HCC) surveillance strategies for patients with advanced fibrosis represents a great burden on healthcare systems. An individualized HCC risk strategy incorporates the dynamic changes of HCC risk are lacking. METHODS This single-centre observational study included 3075 patients, with advanced fibrosis (≥F3) who achieved SVR following DAAs at Egyptian Liver research institute and hospital (ELRIAH) with follow-up period (range 6-72 months). The performance of a recently developed General Evaluation Score (GES) HCC risk stratification score was calculated pre- and post-treatment using Harrell's c statistic. Times to HCC and cumulative incidences were calculated with Kaplan-Meier method and compared using log-rank (Mantel-Cox) test. RESULTS Pre-treatment GES score stratified patients into low (60.4%), intermediate (23.4%), and (16.2%) high-risk score where 5-year cumulative incidences of HCC were 1.66%, 4.45% and 7.64%, respectively. Harrell's c statistic was 0.801. Post-treatment GES score stratified patients into low (57.4%), intermediate (30.7%) and (11.9%) high-risk score where 5-year cumulative incidences of HCC were 1.35%, 3.49% and 11.09% respectively. The cumulative HCC incidence increased significantly with higher scores (P < .001). Harrell's c statistic was 0.818. Using pre- and post-treatment GES score, GES algorithm was developed with higher predictive value. The cumulative HCC incidence increased significantly with higher scores (P < .001). Harrell's c statistic was 0.832. CONCLUSION A dynamic algorithm incorporating both pre- and post-GES scores have better performance and predictive value compared with only pre-treatment assessments. The proposed algorithm would help to stratify those who need intensive or being excluded from screening.

Abstract
BACKGROUND/AIMS Direct-acting antivirals (DAAs) are highly effective in treating chronic hepatitis C virus (HCV)-infected patients. The real-world treatment outcome in Taiwanese patients on a nationwide basis is elusive. METHODS The Taiwan HCV Registry (TACR) programme is a nationwide registry platform including 48 study sites, which is organized and supervised by the Taiwan Association for the Study of the Liver. The primary endpoint was sustained virological response (SVR12, undetectable HCV RNA 12 weeks after end-of-treatment). RESULTS A total of 13 951 registered patients with SVR12 data available were analysed (mean age, 63.0 years; female, 55.9%; HCV genotype-1 [GT1], 57.9%; cirrhosis, 38.4%; preexisting hepatocellular carcinoma [HCC], 10.6%; and hepatitis B virus coinfection, 7.7%). The overall SVR12 rate was 98.3%, with 98.7%, 98.0%, 98.4% and 97.4% in treatment-naïve noncirrhotic, treatment-naïve cirrhotic, treatment-experienced noncirrhotic and treatment-experienced cirrhotic patients, respectively. The SVR12 rate was > 95% across all subgroups except treatment-experienced cirrhotic patients who received sofosbuvir/ribavirin (88.7%), treatment-naïve noncirrhotic patients (94.8%) and treatment-experienced cirrhotic (94.8%) patients who received daclatasvir/asunaprevir. The most important factor associated with treatment failure was DAA adherence < 60% ( adjusted odds ratio [aOR]/95% confidence interval [CI]: 117.1/52.4-261.3, P < .001), followed by GT3/GT2 (aOR/CI: 5.78/2.25-14.9, P = .0003 and aOR/CI: 1.55/1.05-2.29, P = .03, compared with GT1), active hepatocellular carcinoma (aOR/CI: 4.29/2.57-7.16, P < .001), the use of sofosbuvir/ribavirin (aOR/CI: 2.51/1.67-3.77, P < .001) and daclatasvir/asunaprevir (aOR/CI: 3.29/1.94-5.58, P < .001), decompensated liver cirrhosis (aOR/CI: 2.50/1.20-5.22, P = .02) and high HCV viral loads (aOR/CI: 2.16/1.57-2.97, P < .001). CONCLUSIONS DAAs are highly effective in treating Taiwanese HCV patients in the real-world setting. Maintaining DAA adherence and selecting highly efficacious regimens are keys to ensure treatment success.

Abstract
Background Treatment response to antiviral drugs is a challenging issue in patients with chronic hepatitis C virus (HCV) infection. Although microRNA-122 represents the majority of the microRNA content in hepatic tissues, few studies have evaluated its role in the treatment response, so we aimed to study its role in chronic HCV patients and in predicting the treatment response to direct-acting antivirals (DAAs). Methods The study included 125 chronic HCV patients (89 naïve and 36 with a prior failed peginterferon/ribavirin response) and 50 apparently healthy subjects. Complete blood count, liver function, α-fetoprotein, lipid profiles, serum creatinine, abdominal ultrasound, and FibroScan® were assessed. Viral markers, HCV antibodies, and hepatitis B surface antigen were measured by enzyme-linked fluorescent immunoassay, with quantitative estimation of HCV RNA and microRNA-122 levels by real-time PCR. Results The microRNA-122 level in HCV patients (those with a sustained virologic response 12 weeks after finishing therapy [SVR12] and non-responders) was significantly increased compared with controls and expressed more in non-responders versus SVR12 (p=0.042). ROC curve analysis of microRNA-122 for differentiating HCV patients from healthy controls revealed that a cut-off point of >1.45 had a sensitivity of 67.20%, specificity of 94.0%, AUC=0.861, and p<0.001; and for predicting response to treatment a cut-off point ≤5.66 could significantly (p=0.022) predict the occurrence of SVR, with a sensitivity of 60.34%, specificity of 66.67%, and AUC=0.729. Logistic regression analysis showed significant values for microRNA-122 in multivariate and univariate analysis for the prediction of response to DAAs. Conclusion The results demonstrated the possible function of microRNA-122 as an indicative tool for distinguishing chronic HCV patients from controls and in the assessment of the therapeutic reaction to DAAs.

Abstract
BACKGROUND AND AIM Globally, China has the highest chronic hepatitis C (CHC) burden, but its real-world direct-acting antiviral (DAA) data are limited. Our aim is to investigate the real-world outcome of China Food and Drug Administration-approved DAA therapies across mainland China including those with genotype (GT) 3. METHODS The REAL-C is a multinational real-world interferon-free DAA-treated CHC registry of several mainland China and other Asian centers. We evaluated the sustained virological response rate 12 weeks after end of treatment (SVR12), adverse events, and treatment effect on liver function and fibrosis (fibrosis-4 index). RESULTS We analyzed 859 DAA-treated CHC patients (6/1/2017-5/30/2019) from 12 mainland China centers (three municipalities and nine provinces): median age 52, 49.9% male, 33.1% cirrhosis, 95% treatment naïve, and 2.5% HBsAg+ . The most common GT was GT1b (523, 62.2%), followed by GT2a (156, 18.5%), GT3b (74, 8.8%), GT3a (41, 4.9%), and GT6 (37, 4.4%). SVR12 rates were 98.0% overall (95% confidence interval 96.9-98.8%), 98.1% for GT1b, 96.8% GT2a, 100% GT3a, 97.3% GT3b, and 100% GT6. Baseline cirrhosis and male sex but not prior treatment history, renal dysfunction, age, and GTs were associated with SVR12. For both cirrhotic and non-cirrhotic patients, there were significant improvement in liver function tests, alpha fetoprotein, and fibrosis-4 index with SVR12. Serious adverse events were rare (1.1%) with only nine patients discontinuing therapy prematurely and anemia being the most common adverse event (13.1%, mostly with ribavirin). CONCLUSIONS In real-world Chinese patients with diverse GTs, Chinese Food and Drug Administration-approved interferon-free DAAs were well tolerated, provided high cure rates (98.0% overall) including GT3a/3b, and led to improvement of liver function.

Abstract
Simple Summary The wasp Sphecophaga orientalis is a parasitoid of the Oriental hornet (Vespa orientalis) in its subterranean colonies. We describe this parasitoid’s occurrence in hornet nests in Israel and compare the chemical composition of cuticular washes of both species. The dissimilarity between the two excludes the possibility that the parasite uses either camouflage or chemical mimicry to evade host aggression. Because the parasitoid features large amounts of the necrophoric compound oleic acid, we suggest that, due to this compound, the host considers the parasite as refuse and ignores its presence. The parasitoid head also contains rose oxide, a repellent, possibly used to repel aggressive workers and which, combined with its necrophoric odor, enables it to remain in the nest undisturbed. Abstract The main challenge facing a parasite of social insects lies in deceiving its host’s detection and defense systems in order to enter and survive within the host colony. Sphecophaga orientalis is an ichneumonid wasp that parasitizes the pupae of the Oriental hornet Vespa orientalis. In Israel’s Mediterranean region, this parasitoid infects on average 23.48% (8–56%) of the host pupal cells. Observation of colonies brought to the laboratory revealed that the parasite moves around within the colony without being aggressed by the host workers. To assess how the parasite evades host detection and defense, we compared the cuticular hydrocarbon (CHC) profiles of both species. There was little similarity between the parasite and the host workers’ CHC, refuting the hypothesis of chemical mimicry. The parasite’s CHCs were dominated by linear alkanes and alkenes with negligible amounts of branched alkanes, while the host workers’ CHCs were rich in branched alkanes and with little or no alkenes. Moreover, the parasite cuticular wash was markedly rich in oleic acid, previously reported as a cue eliciting necrophoric behavior. Since nests of Oriental hornets are typified by large amounts of prey residues, we suggest that, due to its unfamiliar CHCs and the abundance of oleic acid, the parasite is considered as refuse by the host. We also detected rose oxide in the parasitoid head extracts. Rose oxide is a known insect repellent, and can be used to repel and mitigate aggression in workers. These two factors, in concert, are believed to aid the parasite to evade host aggression.

Abstract
Background Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a primary liver carcinoma with both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) components. We examined the clinicopathological characteristics and recurrence patterns of cHCC-CCA. Because of the rarity of cHCC-CCA, its etiology, clinicopathological features, and prognosis in comparison with other primary liver carcinoma remain unknown. Its recurrence pattern and sites in particular also need to be elucidated. Methods All patients who underwent hepatectomy for primary liver malignancies between 2005 and 2015 were retrospectively included in this study. Results Eight hundred and ninety-four hepatectomies were performed. Nineteen cases of cHCC-CCA (2.1%) in 16 patients were enrolled. Three patients underwent re-hepatectomy. The background of hepatitis viruses and tumor marker patterns of cHCC-CCA were similar to those of HCC and dissimilar to those of intrahepatic CCA (iCCA). Biliary invasion was common in cHCC-CCA and iCCA. The 5-year overall survival values of the cHCC-CCA, HCC, and iCCA patients were 44.7%, 56.6%, and 38.5%, respectively. The 5-year recurrence-free survival values of the cHCC-CCA, HCC, and iCCA patients were 12.2%, 28.7%, and 32.9%, respectively. The liver was the most common recurrence site. Unlike HCC, however, the lymph node was the second-most common recurrence site in both cHCC-CCA and iCCA. Pathological samples of the recurrent lesions were obtained in six patients, and four had cHCC-CCA recurrence pathologically. Conclusion cHCC-CCA had a mixture of characteristics of HCC and iCCA. Many cases of cHCC-CCA remained cHCC-CCA pathologically even after recurrence.

Abstract
BACKGROUND & AIMS Hepatocellular carcinoma (HCC) risk persists after hepatitis C virus (HCV) eradication with direct-acting antivirals (DAAs), particularly in patients with cirrhosis. Identifying those who are likely to develop HCC is a critical unmet medical need. Our aim is to develop a score that offers individualized patient HCC risk prediction. METHODS This two-centre prospective study included 4400 patients, with cirrhosis and advanced fibrosis who achieved a sustained virologic response (SVR), including 2372 patients (derivation cohort). HCC-associated factors were identified by multivariable Cox regression analysis to develop a scoring model for prediction of HCC risk; and subsequently internally and externally validated in two independent cohorts of 687 and 1341 patients. RESULTS In the derivation cohort, the median follow-up was 23.51 ± 8.21 months, during which 109 patients (4.7%) developed HCC. Age, sex, serum albumin, α fetoprotein and pretreatment fibrosis stage were identified as risk factors for HCC. A simple predictive model (GES) score was constructed. The 2-year cumulative HCC incidence using Kaplan-Meier method was 1.2%, 3.3% and 7.1% in the low-risk, medium-risk and high-risk groups respectively. Internal and external validation showed highly significant difference among the three risk groups (P < .001) with regard to cumulative HCC risk. GES score has high predictive ability value (Harrell's C statistic 0.801), that remained robustly consistent across two independent validation cohorts (Harrell's C statistic 0.812 and 0.816). CONCLUSION GES score is simple with validated good predictive ability for the development of HCC after eradication of HCV and may be useful for HCC risk stratification in those patients.

Abstract
Hepatocellular carcinoma (HCC) is typically fatal, and patients with hepatocellular carcinoma are usually diagnosed at the late stages. Although the treatments for HCC have been rapidly advancing, novel targets for HCC are still desperately needed, especially for targeted therapies. Here, we identified an enriched long non-coding RNA, AC006262.5, associated with HCC, that promoted the proliferation, migration, and invasiveness of HCC cells, both in vitro and in vivo. In addition, our results revealed that AC006262.5 bound to and regulated miR-7855-5p, a tumor-suppressive miRNA, in HCC. Moreover, our data show that AC006262.5 regulates the expression of BPY2C via miR-7855-5p. Finally, we found that AC006262.5 and miR-7855-5p formed a regulatory loop. Upregulation of AC006262.5 resulted in decreased expression of miR-7855-5p, and downregulation of miR-7855-5p further facilitated the expression of AC006262.5. Our work provides novel targets for HCC diagnosis and treatment, and sheds light on the lncRNA-miRNA regulatory nexus that controls the pathology of HCC.

Abstract
BACKGROUND A 12-week grazoprevir/elbasvir regimen is highly effective against hepatitis C virus genotype 1 (HCV-1) infection. The efficacy of an 8-week regimen for treatment-naive HCV-1-infected patients with mild fibrosis has not been determined. METHODS Treatment-naive HCV-1b-infected patients with mild fibrosis were randomly assigned to receive 8 (n = 41) or 12 (n = 41) weeks of grazoprevir/elbasvir therapy. The primary end point was a sustained virologic response, defined as an HCV RNA level of < 12 IU/mL, at posttreatment week 12 (SVR12). RESULTS SVR12 was achieved by 87.8% of patients (36 of 41) in the 8-week arm and 100% (41 of 41) in the 8-week arm of the full-analysis population and by 90.0% (36 of 40) and 100% (41 of 41), respectively, in the per-protocol population (all P = .055). In the 8-week arm, a significantly lower SVR12 rate was observed among patients with a high HCV-1b load, defined as ≥1 500 000 IU/mL (79% vs 100%; P = .042), and among those with a baseline Y93H resistance-associated substitution (RAS) frequency of >15% in HCV nonstructural protein 5A (NS5A; 40.0% vs 97.1%; P = .004). Between-group analysis demonstrated that, among patient with a high HCV-1b load and a baseline Y93H RAS frequency of >15%, those in the 8-week arm had a substantially lower SVR12 rate than those in the 12-week arm (40.0% vs 100.0%). All 4 HCV-1b relapses had a Y93H RAS frequency of >99% at posttreatment week 12. CONCLUSIONS Twelve weeks of grazoprevir/elbasvir therapy is highly effective for treatment-naive patients with mild fibrosis. A truncated, 8-week grazoprevir/elbasvir regimen might be applied for those with low viral loads or without a significant NS5A RAS frequency. CLINICAL TRIALS REGISTRATION NCT03186365.

Abstract
BACKGROUND AND AIM Hepatitis C virus eradication via the use of antivirals ameliorates metabolic profiles. The changes in serum uric acid (SUA) levels in chronic hepatitis C patients who receive antivirals are not well understood. We aimed to address this issue by comparing the SUA changes before and after the achievement of a sustained virological response (which is defined as hepatitis C virus RNA seronegativity at 12 weeks after the end of treatment). METHODS Two hundred and thirteen sustained virological response patients who were treated by directly acting antivirals were consecutively enrolled. Pretreatment and post-treatment SUA levels were compared. Hyperuricemia was defined as a uric acid level > 7.0 mg/dL in men and > 6.0 mg/dL in women. RESULTS The SUA levels significantly decreased after treatment, as compared to the pretreatment levels (5.6 ± 1.5 vs 6.0 ± 1.7 mg/dL, respectively; P < 0.001). The proportion of hyperuricemia incidences significantly decreased after treatment (25.8% vs 35.7%, respectively; P = 0.001). The improvement was only observed in patients with a fibrosis-4 index (FIB-4) < 6.5 (25.7% vs 37.1%, P = 0.001) but not in those patients with a FIB-4 ≧ 6.5 (26.3% vs 28.9%, P = 1.00). A multivariate analysis revealed that the factor that was associated with significantly decreased SUA levels was FIB-4 < 6.5 (odds ratio [OR]/95% confidence interval [CI]: 3.22/1.04-9.95, P = 0.04) and estimated glomerular filtration rate < 60 mL/min/1.73 m2 (OR/CI: 4.34/1.94-9.73, P < 0.001). There existed a trend of a higher proportion of patients with significant SUA improvement along with the decrement of FIB-4 (29.7%, 25%, and 10.5% in patients with FIB-4 < 3.25, 3.25-6.5, and > 6.5, respectively; trend P = 0.03). CONCLUSIONS SUA levels were significantly decreased in chronic hepatitis C patients after viral eradication. The improvement was particularly enhanced in patients with mild liver disease.

Abstract
Turnover of membrane proteins or soluble proteins associated to plasma membrane involves clathrin-mediated endocytosis (CME), endosomal trafficking, and vacuolar degradation. Thus, endocytic and endosomal trafficking regulate numerous physiological processes, including mineral transport, hormone signaling, and pathogen response. Abscisic acid (ABA) signaling is triggered upon ABA perception by PYRABACTIN RESISTANCE1 (PYR1)/PYR1-LIKE (PYL)/REGULATORY COMPONENTS OF ABA RECEPTORS (RCAR), which are soluble proteins that can associate to membrane by interaction with members of the C2-domain ABA-related (CAR) protein family and the RING finger of seed longevity (RSL1) E3 ubiquitin ligase. Half-life of PYR/PYL/RCAR ABA receptors is regulated by ubiquitination and degradation in different subcellular compartments. In particular, pharmacological, genetic, and cell biology approaches have been used to study the different steps that encompass from CME to receptor degradation in the vacuole. In this chapter, we will focus on (1) coimmunoprecipitation (co-IP) assays of clathrin heavy chain (CHC) subunits together with HA-tagged PYL4 ABA receptor and (2) analysis of PYL4 delivery to the vacuole using the TMD23-Ub marker.

Abstract
Background: T regulatory cells (Tregs), through variable mechanisms, play a crucial role in Hepatitis C virus (HCV) chronicity and infection tolerance. A great speculation is posed regarding the level, role of Tregs in end-stage renal disease (ESRD), and the presence of associated factors that could influence the Tregs population. Accordingly, we aimed at studying the effect of HCV infection on peripheral CD4+CD25+Tregs population among patients on hemodialysis (HD) as well as the effect of other comorbidities on these cells.Patients and methods: A group of 77 patients on HD (32 were HD HCV+ and 45 were HD HCV-) and 80 healthy controls (HCs) were included in the study. Flow cytometric analysis was performed for identification and quantification of peripheral CD4+ CD25+Tregs.Results: The frequency of CD4+ CD25+Tregs increased significantly in HD patients compared to the HCs (p = <.0001 each). HCV posed no effect on peripheral CD4+ CD25+ Tregs in ESRD patients, when comparing HD HCV- and HD HCV+ groups. In the hypertensive HD HCV-, Tregs percentage was higher than that in the non-hypertensive. However, the difference was not statistically significant. No significant difference was detected between HD HCV- and HD HCV+ patients on the count and percentages of Tregs according to the duration of dialysis.Conclusion: Demonstrating that chronic HCV infection has no effect on CD4+ CD25+ Tregs cells levels in ESRD patients is of great importance to the success of future allografts in such patients.

Abstract
A role for sexual selection in the evolution of insect cuticular hydrocarbons (CHCs) is suggested by observations of selection acting on male CHCs during female mate choice. However, evidence that CHCs evolve in response to sexual selection is generally lacking, and there is a need to extend our understanding beyond well-studied taxa. Experimental evolution offers a powerful approach to investigate the effect of sexual selection on the evolution of insect CHCs. We conducted such an experiment using the dung beetle, Onthophagus taurus. After six, 12 and 21 generations of experimental evolution, we measured the CHCs of beetles from three populations subject to sexual selection and three populations within which sexual selection had been removed via enforced monogamy. We found that the male CHC profile responded to the experimental removal of sexual selection. Conversely, the CHC profile of females responded to the presence of sexual selection but not to its removal. These results show that sexual selection can be an important mechanism affecting the evolution of insect CHCs and that male and female CHCs can evolve independently.

Abstract
BACKGROUND AND AIMS One-third of the global hepatitis C virus (HCV) burden is found in Asia. Real-world data from diverse East Asian cohorts remain limited. This study addressed the real-world status of direct-acting antiviral (DAA) therapy among patients from East Asia. METHODS Chronic hepatitis C (CHC) patients from clinical sites in Japan, Taiwan, South Korea, and Hong Kong were recruited in the REAL-C registry, an observational chart review registry. The primary outcome was sustained virologic response (SVR12, HCV RNA PCR < 25 IU/mL 12 week post-therapy). RESULTS A total of 6287 CHC patients were enrolled. Compared to other East Asian patients, patients from Japan were older (66.3 vs. 61.5 years, p < 0.0001), had lower body mass indices (22.9 kg/m2 vs. 24.6 kg/m2, p < 0.001), and were more likely to have non-liver malignancy history (12.2% vs. 5.0%, p < 0.001).The overall SVR12 rate was 96.4%, similar to patients both inside and outside Japan (96.6% vs. 96%, p = 0.21). The SVR12 rate ranged from 91.1 to 99.4% except treatment-experienced cirrhotic HCV genotype-1 patients who received daclatasvir/asunaprevir (85.9%) and the treatment-experienced cirrhotic HCV genotype-2 patients treated with sofosbuvir/ribavirin (87%). The overall rate of drug discontinuation was 1.9%, also similar across regions. On multivariate regression analyses, there was no significant association between geographic region and SVR outcomes. CONCLUSIONS In this large multinational CHC cohort from the East Asia, oral DAAs were highly effective and well tolerated across the region. Policies should encourage treatment for all CHC patients with DAAs in Asia with its heavy burden of HCV.

Abstract
Clathrin regulates mitotic progression, in addition to membrane trafficking. However, the detailed regulatory mechanisms of clathrin during mitosis remain elusive. Here, we demonstrate novel regulation of clathrin during mitotic phase of the cell cycle. Clathrin heavy chain (CHC) was phosphorylated at T606 by its association partner cyclin G-associated kinase (GAK). This phosphorylation was required for proper cell proliferation and tumor growth of cells implanted into nude mice. Immunofluorescence analysis showed that the localization of CHC-pT606 signals changed during mitosis. CHC-pT606 signals localized in the nucleus and at the centrosome during interphase, whereas CHC signals were mostly cytoplasmic. Co-immunoprecipitation suggested that CHC formed a complex with GAK and polo-like kinase 1 (PLK1). Depletion of GAK using siRNA induced metaphase arrest and aberrant localization of CHC-pT606, which abolished Kiz-pT379 (as a phosphorylation target of PLK1) signals on chromatin at metaphase. Taken together, we propose that the GAK_CHC-pT606_PLK1_Kiz-pT379 axis plays a role in proliferation of cancer cells.

Abstract
Shikonin, a naphthoquinone derivative isolated from the root of Lithospermum erythrorhizon, exhibits broad-spectrum antitumor activity via different molecular mechanisms. In this study, we investigated the effect of shikonin on mitochondrial dysfunction in hepatocellular carcinoma (HCC). Our results showed that shikonin inhibited the proliferation, migration, and invasiveness of HCCLM3 cells, and promoted cell apoptosis in a dose-dependent manner. More importantly, shikonin affected mitochondrial function by disrupting mitochondrial membrane potential and oxidative stress (OS) status. Furthermore, shikonin decreased the oxygen consumption rate of HCCLM3 cells, as well as the levels of ATP and metabolites involved in the tricarboxylic acid cycle (TCA cycle). We also investigated the molecular mechanisms underlying the regulation of mitochondrial function by shikonin as an inhibitor of PKM2. Shikonin decreased the expression of PKM2 in the mitochondria and affected other metabolic pathways (AMPK and PGC1α pathways), which aggravated the oxidative stress and nutrient deficiency. Our results indicate a novel role of shikonin in triggering mitochondria dysfunction via the PKM2-AMPK-PGC1α signaling pathway and provide a promising therapeutic approach for the treatment of HCC.

Abstract
Gastrointestinal cancers account for more cancer-related deaths than any other organ system, owing in part to difficulties in early detection, treatment response assessment, and post-treatment surveillance. Circulating biomarkers hold the promise for noninvasive liquid biopsy platforms to overcome these obstacles. Although tumors shed detectable levels of degraded genetic material and cellular debris into peripheral blood, identifying reproducible and clinically relevant information from these analytes (eg, cell-free nucleotides, exosomes, proteins) has proven difficult. Cell-based circulating biomarkers also present challenges, but have multiple advantages including allowing for a more comprehensive tumor analysis, and communicating the risk of metastatic spread. Circulating tumor cells have dominated the cancer cell biomarker field with robust evidence in extraintestinal cancers; however, establishing their clinical utility beyond that of prognostication in colorectal and pancreatic cancers has remained elusive. Recently identified novel populations of tumor-derived cells bring renewed potential to this area of investigation. Cancer-associated macrophage-like cells, immune cells with phagocytosed tumor material, also show utility in prognostication and assessing treatment responsiveness. In addition, circulating hybrid cells are the result of tumor-macrophage fusion, with mounting evidence for a role in the metastatic cascade. Because of their relative abundance in circulation, circulating hybrid cells have great potential as a liquid biomarker for early detection, prognostication, and surveillance. In all, the power of the cell reaches beyond enumeration by providing a cellular source of tumor DNA, RNA, and protein, which can be harnessed to impact overall survival.

Abstract
The host immune system plays a key role in the elimination of infected cells which depend on killer-cell immunoglobulin-like receptors (KIR), human leucocyte antigen (HLA) class I molecules and their combinations. To evaluate the roles of HLAclass I, KIR genes and their combination in Chronic hepatitis C virus (HCV) infection (CHC), a total of 301 CHCs and 239 controls in a Chinese Han population were included for HLA and KIR genotyping using next-generation sequencing and multiplex PCR sequence-specific priming, respectively. The allele frequency of HLA-C*08:01 was significantly higher in the CHCs than that of the controls (0.088 vs. 0.040, OR = 2.332, 95%CI: 1.361-3.996, p = 0.022), while the frequencies of B*13:01 (0.032 vs. 0.084, OR = 0.357, 95%CI: 0.204-0.625, p = 0.009) and C*08:04 (0.008 vs. 0.038, OR = 0.214, 95%CI: 0.079-0.581, p = 0.022) were significantly lower in the CHCs. The frequencies of haplotype A*11:01-C*08:01 were higher in the CHCs (0.058 vs. 0.019, OR = 3.096, 95%CI: 1.486-6.452, p = 0.026), while haplotype B*13:01-C*03:04 were lower in the CHCs compared to the controls (0.028 vs. 0.071, OR = 0.377, 95%CI: 0.207-0.685, p = 0.012). No association of CHC with KIR genes, genotypes, or haplotypes, as well as HLA/KIR combinations was observed. Our results indicated that HLA-C*08:01 was a risk factor for CHC, while HLA-C*08:04 and HLA-B*13:01 were protective factors against CHC. Haplotypes HLA-A*11:01-C*08:01 could increase susceptibility to CHC, while HLA-B*13:01-C*03:04 could be protective against CHC in the Chinese Han population.

Abstract
BACKGROUND/PURPOSE Treatment with daclatasvir plus asunaprevir (DCV + ASV) for 24 weeks provided a sustained virologic response (SVR) rate of over 90% in hepatitis C virus genotype 1b (HCV-1b) infected patients without non-structural 5A (NS5A) resistance-associated substitutions (RASs) at the L31 and Y93 sites. In this study, we investigated whether adding ribavirin to the DCV + ASV combination could shorten the original treatment regimen to 12 weeks without compromising the treatment efficacy for HCV-1b patients without NS5A RASs. METHODS In the prospective, open-label, single-arm, nationwide multi-center phase III study, a total of 70 interferon-naïve or interferon-experienced HCV-1b patients without baseline L31/Y93 RASs received daclatasvir (60 mg/day) and asunaprevir (100 mg twice daily) plus weight-based ribavirin (1000-1200 mg/day) for 12 weeks, with a 12-week post-treatment follow-up. The primary end-point was the rate of undetectable HCV RNA 12 weeks post-treatment (SVR12). RESULTS The SVR12 rate was 97.1% (68/70) and 100% (68/68) in the full-analysis-set and the per-protocol population, respectively. None of the 68 patients who completed the 12-week treatment experienced relapse during post-treatment follow-up. Two patients withdrew from the study at treatment days 21 and 34 due to anorexia and fatigue, which were considered ribavirin-related and resolved post medication cessation. A total of 4 serious adverse events were reported and considered treatment-unrelated. No deaths or grade 4 adverse events requiring hospitalization was observed throughout the study. CONCLUSION Truncated regimen of DCV + ASV plus ribavirin for 12 weeks was highly effective and safe in HCV-1b patients without NS5A L31/Y93 RAS.

Abstract
BACKGROUND AND AIM Major histocompatibility complex class I chain-related A (MICA) genetic variants and their serum levels (sMICA) were associated with the development of hepatitis C virus-related hepatocellular carcinoma (HCC) in untreated cohorts. The dynamic changes in serial sMICA levels and their association with HCC in the post-curative status are elusive. METHODS Single nucleotide polymorphism rs2596542 of MICA and serial sMICA levels were analyzed in chronic hepatitis C patients with a sustained virologic response after antivirals. Forty-two patients who developed HCC and 84 age-matched, gender-matched, and cirrhosis propensity score-matched non-HCC controls were compared. Serial sMICA levels were measured within 6 months before treatment initiation (pre-sMICA), 6 months after the end of treatment (post-sMICA), and on the last visit before the development (or not) of HCC (last-sMICA). RESULTS Cox regression analysis revealed that last-sMICA was the only predictive factor of HCC development (hazard ratio/95% confidence interval: 2.27 (per 1 log pg/mL increase)/1.672-3.082, P < 0.001). Patients without HCC development showed a significantly reduced trend of sMICA levels during follow-up (trend P = 0.001), which was observed only in GG genotype (trend P < 0.001) but not A allele carriers (P = 0.88). In contrast, patients with HCC showed an increased trend of sMICA levels (trend P = 0.024). However, only the GG genotype "high expressors" (trend P = 0.06) but not A allele carriers (P = 0.18) showed a correlation of substantially increased trend of sMICA levels and HCC development. CONCLUSIONS Serial sMICA levels were associated with HCC development in SVR patients. The clinical utility of this finding is restricted to MICA rs2596542 GG genotype carriers.

Abstract
Chronic hepatitis C (CHC) is a complex disease that can affect different metabolic processes, including glucose and lipid metabolic pathways, with a significant impact on the development of heart disease and stroke. Recent therapy with direct-acting antivirals (DAAs), beyond its high efficacy on CHC eradication, showed a beneficial impact on glucose and lipid metabolism. This review aimed to describe current evidence regarding the association between hepatitis C virus (HCV) infection and impairment of glucose and lipid metabolism and also discusses potential public-health implications in light of the new DAA therapies and their availability at a global level. The excellent safety profile and efficacy of DAAs offer an exceptional opportunity to control the HCV pandemic at a global level and represent an opportunity for developing an operational research framework aimed at investigating the complex dynamics between host, pathogen and therapy that lead to metabolic damage in subjects with infectious diseases.

Abstract
Liver coinfection by hepatitis B virus (HBV) and hepatitis D virus (HDV) can result in a severe form of hepatocellular carcinoma with poor prognosis. Coinfection with HDV and HBV causes more deleterious effects than infection with HBV alone. Clinical research has shown that glutathione S-transferase P1 (GSTP1), a tumor suppressor gene, is typically downregulated in liver samples from hepatitis-infected patients. In the present study, our data indicated that small HDV antigen (s-HDAg) could specifically bind to GSTP1 mRNA and significantly downregulate GSTP1 protein expression. For the human fetal hepatocyte cell line L-02, cells transfected with s-HDAg, along with decreased GSTP1 expression, there was a significant accumulation of reactive oxygen species (ROS) and increased apoptotic ratios. Restoring GSTP1 expression through silencing s-HDAg via RNAi or overexpressing exogenous GSTP1 could largely recover the abnormal cell status. Our results revealed a novel potential mechanism of HDV-induced liver injury and hepatocarcinogenesis: s-HDAg can inhibit GSTP1 expression by directly binding to GSTP1 mRNA, which leads to accumulation of cellular ROS, resulting in high cellular apoptotic ratios and increased selective pressure for malignant transformation. To our knowledge, this is the first study to examine s-HDAg-specific pathogenic mechanisms through potential protein-RNA interactions.

Abstract
Background/Aims Genetic variants of MHC class I polypeptide-related chain A (MICA) at rs2596542 have been associated with hepatocellular carcinoma. The linkage between serum MICA (sMICA) and liver fibrosis in chronic hepatitis C is elusive. Results Linear regression analysis revealed that sMICA were independently correlated to α-fetoprotein (β: 0.149; 95% confidence interval [CI]: 0.001, 0.003; P = 0.007)and MICA rs2596542 GG genotype (β: 0.209; 95% CI: 0.153, 0.483; P < 0.001). While patients were stratified by MICA genetic variants, advanced fibrosis was the only factor independently correlated to sMICA among A allele carriers (β: 0.234; 95% CI: 0.107, 0.543; P = 0.004) but not among non-A allele carriers. Logistic regression analysis revealed that factors associated with advanced liver fibrosis was sMICA (OR/CI: 2.996/1.428–6.287, P = 0.004) and platelet counts (OR/CI: 0.988/0.982–0.994, P < 0.001) in MICA rs2596542 A allele carriers. sMICA > 50 pg/mL provided a positive predictive value of 72 % in predicting advanced liver fibrosis (F3-4) and of 90% in significant fibrosis (> F2) in MICA rs2596542 A allele carriers. Materials and Methods Serum level and single nucleotide polymorphism at rs2596542 of MICA were tested for the association with liver fibrosis in 319 biopsy proven chronic hepatitis C patients. Conclusions Levels of sMICA were highly correlated to liver disease severity in chronic hepatitis C patients who carried the MICA rs738409 A allele. Patients possessing the genetic predisposition had a higher likelihood of progressed liver fibrosis if they expressed higher sMICA levels.

Abstract
Termites evolved eusociality independently from social Hymenoptera. As a common trait, reproductive monopoly is maintained through chemical communication. The queen (and in termites also a king) prevents workers from reproduction by conveying their reproductive status. In termites all soldiers are sterile, but workers' potential to reproduce differs between species. It ranges from totipotency in wood-dwelling lower termites where workers are a transient stage from which all other castes develop, to sterile workers in some higher termites. Intermediate are species in which workers can develop into replacement sexuals within the nest but not into winged sexuals. I summarize the patchy picture about fertility signaling that we currently have for termites, pointing also to potential conflicts over reproduction that differ from those in social Hymenoptera. Recent findings imply that, similar to many social Hymenoptera, wood-dwelling termites that live in confined nests use long-chain cuticular hydrocarbons (CHCs) as fertility signals. Yet other compounds are important as well, comprising proteinaceous secretions and especially volatiles. For a subterranean termite, two volatiles have been identified as primer pheromones that prevent reproductive differentiation of workers. It requires more data to test whether wood-dwelling termites use CHCs, while species with larger colonies and less confined nests use volatiles, or whether all species rely on multicomponent signals. Ultimately, we need more effort to model and test potential conflicts over reproduction between queens, kings and workers. Here results from social Hymenoptera cannot be transferred to termites as the latter are diploid and commonly inbred. This review illustrates promising future research avenues.

Abstract
INTRODUCTION Combined hepatocellular-cholangiocarcinoma (CHC or cHCC-CC) is a rare primary liver tumor displaying histological features of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA). Most patients are not suitable for surgery because of the advanced stage of the disease at the moment of diagnosis. We decided to review the literature in order to identify the outcomes after liver transplantation for CHC and to clarify which is the most appropriate treatment. MATERIAL AND METHODS A systematic literature search was performed. Studies reporting outcomes of liver transplantation (LT) for CHC and studies comparing oncologic outcomes after LT versus liver resection (LR) for CHC were included in this review. RESULTS The mean 5-y Disease Free Survival (DFS) reported in literature is 45.4%, while the mean 5-y overall survival (OS) is 41.8%, analyzing a cohort of 418 cases. The mean DSF in our series after LT was 7.97 months, while the mean OS was 11.7 months. CONCLUSIONS LT should be avoided for the treatment of CHC, in order to allocate organs for more appropriate diseases. Moreover, surgical resections, and in particular major hepatectomies, seem to be associated with acceptable outcomes. An accurate preoperative management is needed, and the use of PET-CT when differential diagnosis is difficult should be considered.

Abstract
Posttransplant hepatitis C virus (HCV) recurrence is universal in chronic hepatitis C recipients. Antiviral therapy is suggested after liver transplant to halt disease progression. Pegylated interferon plus ribavirin therapy remains the standard of care in many areas where direct antiviral agents are poorly accessible. This study aimed to assess the treatment efficacy and safety of the regimen for Taiwanese patients with post-transplant HCV recurrence. Nine patients with HCV recurrence postliver transplantation were allocated. Patients received either pegylated interferon α-2a 180 μg/wk or pegylated interferon α-2b 1.5 mg/kg/wk plus ribavirin for 24-48 weeks. The primary endpoint was the achievement of sustained virological response (SVR), defined as undetectable HCV RNA throughout 6 months of follow-up after the end of treatment. The safety profiles were also documented. The rates of rapid virological response, early virological response, end-of-treatment virological response, and SVR were 33%, 63%, 75%, and 56% respectively. Of the four patients who failed antiviral treatment, the treatment responses were nonresponse (n = 1), loss of follow-up (n = 1), and relapse (n = 2). Three patients terminated therapy early due to severe adverse events, including severe anemia, intra-abdomen infection, and hepatocellular carcinoma recurrence. One of the three patients who terminated treatment early at Week 6 experienced rapid virological response followed by SVR. Pegylated interferon/ribavirin combination allowed a chance for cure with a fair SVR rate in Taiwanese chronic hepatitis C patients postliver transplantation. Early identification of side effects and careful monitoring during therapy might enhance the treatment efficacy.

Abstract
BACKGROUND/AIMS The erythropoiesis in hepatitis C virus infection is unclear. We aimed to evaluate the erythropoietic components in chronic hepatitis C (CHC) patients. METHODS The red blood cell (RBC) components, serum erythropoietin (EPO) levels, and their relationship to clinical characteristics were evaluated between 124 age-matched and sex-matched healthy controls and 248 histology-proven CHC patients. RESULTS Chronic hepatitis C patients had significantly higher serum levels of EPO (1.44 ± 0.36 log mIU/mL versus 1.03 ± 0.31 log mIU/mL, P < 0.0001) and lower hemoglobin (Hb) concentrations (14.6 ± 1.4 g/dL versus 15.3 ± 1.2 g/dL, P < 0.001) as compared with healthy controls. Among the CHC patients, the serum EPO level was negatively associated with the Hb concentration (β = -0.227; 95% confidence intervals [CI]: -0.09-0.027; P < 0.001) and RBC counts (β = -0.204; 95% CI: -0.245-0.061; P = 0.001) and was positively correlated with necroinflammatory activity (β = 0.201; 95% CI: 0.009-0.046; P = 0.003) and fibrosis (β = 0.143; 95% CI: 0.003-0.076; P = 0.04) of liver histopathology. For non-cirrhotic CHC patients, the severity of liver necroinflammatory activity was positively correlated with the reticulocyte and serum EPO levels (P = 0.001 and 0.008, respectively), and negatively related to the RBC counts (P = 0.03). Using stepwise multivariate linear regression analysis, the grade of necroinflammatory activity was positive (β = 0.214; 95% CI: 0.046-0.209, P = 0.002), whereas the Hb concentration was inversely (β = -0.205; 95% CI: -0.09-0.018, P = 0.004) associated with the serum EPO levels in CHC patients. CONCLUSIONS The disease activity in CHC patients had a negative impact on erythropoiesis with compensatory higher but blunted EPO responses.

Abstract
BACKGROUND AND AIM Pathological iron overload is commonly found in chronic hepatitis C (CHC) patients and considered as a negative prognostic factor of the disease. A single nucleotide polymorphism (SNP) rs884409 in duodenal cytochrome b gene (CYBRD1) is implicated in the pathogenesis of hemochromatosis. In our study we investigated the impact of the CYBRD1 genotype and expression on iron overload in CHC patients. METHODS Liver biopsy specimens and whole blood samples from 243 patients with CHC were included in the study. Iron deposits in hepatocytes, serum markers of iron overload, and expression profile of gene-regulators of iron homeostasis were analyzed. Genotyping and analysis of gene expression of the CYBRD1 were performed. The frequency of SNP and the expression levels of CYBRD1 were compared between the groups of patients with and without markers of iron overload. RESULTS The single nucleotide variant rs884409 G was associated with elevated serum iron levels, increased markers of liver inflammation, and oxidative stress. Hepatic expression of CYBRD1 was associated with the expression of Tfr2, Id1, and HO-1 genes, serum ferritin levels, and with increased iron accumulation in liver. CONCLUSION These results implicate CYBRD1 involvement in iron homeostasis in CHC.

Abstract
The rate of liver fibrosis progression in chronic hepatitis C (CHC) patients is highly variable and affected by different factors. This study aimed to assess the role of cirrhosis risk score (CRS) based on 7 genetic variants (7 single-nucleotide polymorphisms [SNPs]) and host factors (age and sex) in the prediction of the rate of fibrosis progression in CHC. Duration of infection was determined in 115 patients. The fibrosis progression rate (FPR) per year was calculated as the ratio between fibrosis stage and the duration of infection. SNP genotyping were performed and CRS was determined based on it. FPR was significantly elevated in patients who acquired infection at age >40 years versus those who acquired infection at 30-40 years and those who acquired infection at <30 years. Median FPR was significantly higher in males than females (0.17 vs. 0.15) with P = 0.001. CRS value ≥0.8 is predictive of patients with high risk for cirrhosis, and CRS value <0.5 is predictive of patients with low risk for cirrhosis. There was significant positive correlation between CRS and FPR (P ≤ 0.001). CRS based on 7 SNPs at cutoff value ≥0.8, age at infection >40 years, and male sex are predictors of higher FPR.

Abstract
BACKGROUND & AIMS Hepatitis E (HEV) can cause acute-on-chronic liver failure in persons with pre-existing liver disease. We investigated whether HEV infection contributes to hepatic decompensation in patients with previously stable, advanced chronic hepatitis C. METHODS We performed a case-control study using stored serum samples from subjects enrolled in the randomized phase of the Hepatitis C Antiviral Long-Term Treatment Against Cirrhosis Trial (n = 1050; mean age, 51 y; 70% male; 40% with cirrhosis at baseline). Cases were subjects who developed hepatic decompensation within a 24-week period. Controls (3 per case) were subjects without hepatic decompensation matched for fibrosis stage and followed up for a similar period. A serum sample obtained within 6 months after the decompensation event in cases and the same follow-up period in controls were tested for anti-HEV IgG. Subjects with a positive result had a baseline sample similarly tested for anti-HEV IgG. We measured levels of anti-HEV IgM and HEV RNA in blood samples from incident cases. RESULTS Of the 1050 subjects analyzed, 314 (30%) experienced a clinical event. Of the 314 subjects who experienced decompensation as defined, 89 (28%) were tested for anti-HEV, along with 267 controls (without decompensation). Similar proportions of cases and controls tested positive for anti-HEV (22.5% and 20.6%, respectively; P = .70). Ten incident HEV infections were identified-4 in cases (4.5%) and 6 in controls (2.2%) (P = .28). HEV RNA was not detected in blood samples from the 10 incident infections. Only 2 of the 4 incident infections among cases were related temporally to the decompensation event. CONCLUSIONS HEV does not appear to be a significant cause of hepatic decompensation among persons with previously stable, advanced chronic hepatitis C in the United States.

Abstract
BACKGROUND AND AIMS Many studies have been published on the association between IFNL4 rs368234815 single-nucleotide polymorphism (SNP) and sustained virological response (SVR) in chronic hepatitis C (CHC) patients undergoing treatment with PEGylated interferon (PEG-IFN) plus ribavirin (RBV). Because of the variable and sometimes inconsistent results, we performed a meta-analysis to estimate the association between these factors. METHODS We conducted a search of the literature published prior to July 1, 2014. The pooled results were analyzed as the odds ratios (ORs) and corresponding 95% confidence intervals (CIs) using random-effect model. RESULTS The pooled results revealed that the rs368234815 TT/TT genotype was significantly correlated with SVR in HCV-1/4-infected Caucasian patients (OR=4.65, 95% CI=3.36-6.42, P<0.00001) but not in HCV-2/3-infected Caucasian patients (OR=1.44, 95% CI: 0.89-2.33, P=0.13). Conversely, the rs368234815 ΔG/ΔG genotype was significantly linked to treatment failure in Caucasian patients (OR=0.49, 95% CI: 0.38-0.64, P<0.00001), regardless of the HCV genotype. CONCLUSION The results of the meta-analysis suggest that IFNL4 rs368234815 polymorphism may be a predictor of SVR in Caucasian HCV-1/4-infected patients.

Abstract
BACKGROUND & AIMS We tested the putative association of the rs58542926 variant of TM6SF2, a recently described genetic determinant of nonalcoholic fatty liver disease, with steatosis and fibrosis in genotype 1(G1) chronic hepatitis C(CHC) patients. METHODS A total of 694 consecutively biopsied Caucasian G1 CHC patients were genotyped for TM6SF2 rs58542926, IL28B rs12979860 and PNPLA3 rs738409. Steatosis was classified as absent (<5%), mild-moderate(5-29%) and severe(≥30%), Fibrosis was considered severe if=F3-F4. RESULTS Carriers of TM6SF2 rs58542926 (6.3% of patients) exhibited lower serum levels of cholesterol (P = 0.04) and triglycerides (P = 0.01), but a similar distribution of steatosis severity (P = 0.63), compared to noncarriers. Prevalence and severity of steatosis were reduced in IL28B C allele carriers (P = 0.005) and elevated in PNPLA3 G allele carriers (P < 0.001). After adjustment for age, gender, body mass index and homoeostasis model assessment score, steatosis severity was independently associated with IL28B rs12979860 (odds ratio [OR] 0.69, 95% confidence interval [CI] 0.55-0.86, P = 0.001) and PNPLA3 rs738409 (OR 1.84, 95% CI 1.46-2.83, P < 0.001), but not TM6SF2 rs58542926 (OR 1.48, 95% CI 0.82-2.69, P = 0.19). Variants of TM6SF2 (30.9% vs. 25%, P = 0.40), IL28B and PNPLA3 were not directly associated with fibrosis severity, although variants of IL28B and PNPLA3 promoted steatosis (OR 1.36, 95% CI 1.06-1.75, P = 0.01) that in turn is associated with severe fibrosis. CONCLUSIONS In G1 CHC patients, TM6SF2 rs58542926 does not affect the histological severity of liver damage. However, IL28B rs12979860 and PNPLA3 rs738409 modify steatosis.

Abstract
CONTEXT The objective of the current study was to evaluate the association between the I148M variant of patatin-like phospholipase domain-containing protein 3 (PNPLA3) and the presence of Chronic Hepatitis C (CHC) across different populations. EVIDENCE ACQUISITION This study was a meta-analysis of all relevant researches published in the literature from year 2000 to 2015. The odds ratios (ORs) of PNPLA3 allele distributions in CHC patients were analyzed and compared with healthy controls. The meta-analysis Revman 5.2 software was applied for investigating heterogeneity among individual studies and for summarizing all the studies. The meta-analysis was carried out according to the Cochrane Reviewers' Handbook recommendations. A total of 120 clinical trials or reports were retrieved, yet only five trials met the study selection criteria. RESULTS Five hospital-based case-control studies were included in the final analysis. The overall frequency of PNPLA3 gene polymorphisms was 20.4% (205/1005) in CHC and 10.23% (53/518) in controls. The summary odds ratio for the association of gene polymorphisms of PNPLA3 with the risk for CHC was determined as 2.20 (95% CI: 1.56 -3.11) and was statistically significant (P < 0.05). CONCLUSIONS The current meta-analysis showed an association between frequency of GG genotype of PNPLA3 and the risk of development of CHC in various populations throughout the world.

Abstract
Many studies have demonstrated a potential association between type 2 diabetes (T2D) and hepatitis C virus infection in Western countries, while similar evidence is limited in Asia. We compared the prevalence of glucose abnormalities (impaired fasting glucose [IFG] and T2D) and their risk factors between Asian and non-Asian chronic hepatitis C (CHC) patients, and evaluated whether glucose abnormalities impacted the viral responses to peginterferon plus ribavirin treatment (current standard of care in most Asian countries). This study retrospectively analyzed data of 1,887 CHC patients from three Phase II/III studies with alisporivir (DEB025) as treatment for CHC. The chi-square test was used to compare the prevalence of IFG/T2D between Asian and non-Asian CHC patients, and logistic regression was used to adjust for sex, age, and cirrhosis status. Risk factors for IFG/T2D were evaluated using univariate and multivariate analysis. Our results indicated that the prevalence of IFG/T2D was high in both Asian and non-Asian CHC patients (23.0% vs 20.9%), and no significant difference was found between these two populations (adjusted odds ratio: 1.3, 95% confidence interval: 0.97, 1.7; P=0.08). Age, sex, and cirrhosis status were risk factors for IFG/T2D in both populations, while body mass index was positively associated with IFG/T2D in non-Asian but not in Asian participants. No significant differences in sustained virological response rates were seen between patients with normal fasting glucose and patients with IFG/T2D for both populations. These results demonstrate that the prevalence of glucose abnormalities in Asian CHC patients was similar to that in non-Asians, and glucose abnormalities had no impact on viral response to peginterferon plus ribavirin.

Abstract
The Coalition for a Healthier Community (CHC) initiative was implemented to improve the health and well-being of women and girls. Underpinning CHC is a gender-based focus that uses a network of community partners working collaboratively to generate relevant behavior change and improved health outcomes. Ten programs are trying to determine whether gender-focused system approaches are cost-effective ways to address health disparities in women and girls. Programs implemented through coalitions made up of academic institutions, public health departments, community-based organizations, and local, regional, and national organizations, are addressing health issues such as domestic violence, cardiovascular disease prevention, physical activity, and healthy eating. Although these programs are ongoing, they have made significant progress. Key factors contributing to their early success include a comprehensive needs assessment, robust coalitions, the diversity of populations targeted, programs based on findings of the needs assessments, evaluations taking into consideration the effect of gender, and strong academic-community partnerships. A noteworthy impact of these programs has been their ability to shape and impact public, social, and health policies at the state and local levels. However, there have been challenges associated with the implementation of such a complex program. Lessons learned are discussed in this paper.

Abstract
PURPOSE The addition of 2 direct-acting antiviral (DAA) agents, telaprevir and boceprevir, to peginterferon and ribavirin therapy significantly improves sustained virologic response rates in patients treated for chronic hepatitis C virus (CHC) but is associated with a higher risk of adverse events (AEs), including anemia and rash. Using a large administrative claims database, this study compared the health care resource utilization and costs among CHC patients who developed anemia and/or rash while receiving DAA-based therapies (telaprevir and boceprevir) versus those who did not develop anemia or rash. Adjusted costs were compared by using regression analysis. METHODS Adult patients with ≥1 CHC diagnosis and a prescription for boceprevir or telaprevir were selected from a US-based claims database. The date of the first DAA fill after May 13, 2011, was defined as the index date. Patients were required to have continuous eligibility and no claims for hepatitis B treatment during the 6 months before (baseline) and 12 months after (study period) the index date. Patients were categorized into 4 cohorts based on the development of anemia only, rash only, both anemia and rash (anemia/rash), or neither anemia nor rash (NAR) while receiving DAA-based therapies. Baseline characteristics and study period health care utilization and costs were compared by using univariate statistics between cohorts that developed anemia only, rash only, or anemia/rash and the cohort that did not develop anemia or rash. Adjusted costs were compared by using multivariable regressions. FINDINGS A total of 2862 patients were identified and categorized into 4 cohorts: 1204 anemia only, 131 rash only, 188 anemia/rash, and 1339 NAR patients. During the study period, patients developing anemia and/or rash incurred significantly more outpatient, dermatologist, and total medical visits compared with the NAR cohort. The anemia-only and anemia/rash cohorts also had significantly more inpatient, emergency department, and hematologist visits, as well as significantly higher adjusted total medical costs ($18,285 and $21,435 vs $11,253), total drug costs ($76,723 and $79,689 vs $63,001), and non-CHC drug costs ($10,391 and $10,475 vs $2437). The rash-only cohort had comparable adjusted total medical and drug costs. IMPLICATIONS CHC patients who developed anemia while receiving DAA-based therapies incurred significantly higher resource utilization and costs compared with those who did not. The study highlights the need for new CHC treatment regimens that are associated with fewer and less severe AEs, particularly anemia.

Abstract
BACKGROUND & AIMS Genetic variants of patatin-like phospholipase domain-containing 3 (PNPLA3) and diabetes are associated with liver disease severity, in patients with chronic hepatitis C (CHC) infection. We aimed at exploring their interaction in determining hepatitis C virus (HCV)-related liver fibrosis. METHODS The PNPLA3 genetic polymorphism at rs738409 was verified in 1077 biopsy-proven CHC patients. Other clinical variables, including diabetes status, were analysed for factors associated with bridging fibrosis. RESULTS Patients with advanced liver fibrosis had higher proportions of the GG genotype (14.5% vs. 10.4%, p=0.06 in recessive model) and GG/GC genotype carriage (64.0% vs. 56.8%, p=0.03 in dominant model). Stepwise logistic regression analysis revealed that factors predictive of advanced liver fibrosis included age (odds ratio [OR]: 1.02, 95% confidence intervals [CI]: 1.008-1.037, p=0.002), diabetes (OR: 1.81, CI: 1.236-2.653, p=0.002), α-fetoprotein (OR: 1.006, CI: 1.001-1.01, p=0.01), platelet counts (OR: 1.009, CI: 1.006-1.012, p<0.001), and PNPLA3 rs738409 CG/GG genotype (OR: 1.34, CI: 1.006-1.785, p=0.046). When patients were grouped according to their diabetes status, the PNPLA3 genetic variants were associated with advanced liver fibrosis in diabetic patients only, but not in non-diabetic patients. The PNPLA3 gene was the most important predictive factor of bridging fibrosis in diabetic patients, using the recessive model (OR: 4.53, CI: 1.356-15.106, p=0.014) or the dominant model (OR: 2.20, CI: 1.026-4.734, p=0.04). Compared to non-diabetic patients, patients with the diabetes/GG genotype were more likely to have advanced liver fibrosis (OR: 8.79, CI: 2.889-26.719, p<0.001), followed by those with diabetes/non-GG genotype (OR: 1.55, CI: 1.048-2.286, p=0.03). CONCLUSIONS The effect of PNPLA3 genetic variants in HCV-related advanced liver fibrosis was enhanced in diabetic patients. The strong genetic-environmental interaction contributed to the high risk of advanced liver disease in CHC patients.
