Metformin and statins reduce hepatocellular carcinoma risk in chronic hepatitis C patients with failed antiviral therapy.

Backgrounds and Aim: Chronic hepatitis C (CHC) patients who fail antiviral therapy have a high risk of developing hepatocellular carcinoma (HCC). We investigated the effects of metformin and statins, commonly used to treat diabetes mellitus (DM) and hyperlipidemia (HLP), on HCC risk in CHC patients who failed antiviral therapy. Methods: CHC patients with failed interferon-based therapy were enrolled in a large-scale multicenter cohort study in Taiwan (T-COACH). HCC occurrence 1.5 years after the end of antiviral therapy was identified by linking to the cancer registry databases from 2003 to 2019. After considering death and liver transplantation as competing risks, Gray's cumulative incidence and Cox sub-distribution hazards for HCC development were used. Results: Among the 2,779 CHC patients, 480 (17.3%) developed new-onset HCC and 238 (8.6%) died after antiviral therapy. Metformin non-users with DM had a 51% higher risk of liver cancer than patients without DM, while statin users with HLP had a 50% lower risk of liver cancer than patients without HLP. The 5-year cumulative incidence of HCC was 16.5% in metformin non-users, significantly higher in metformin non-users than in patients without DM (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Conversely, HLP statin users had a significantly lower HCC risk than patients without HLP (3.8% vs. 12.5%; aSHR=0.50; P<0.001). Notably, the unfavorable effect of non-metformin use on increased HCC risk was mainly observed among patients without cirrhosis but not in patients with cirrhosis. In contrast, a favorable effect of statins reduced the risk of HCC in both cirrhotic and non-cirrhotic patients. Conclusion: Metformin for DM and statins for HLP have chemopreventive effects on HCC risk in CHC patients who failed antiviral therapy. These findings emphasize the importance of personalized preventive strategies for managing patients with these clinical profiles.

New insight into the intravenous immunoglobulin treatment in Multisystem Inflammatory Syndrome in children and adults.

Within 6 months of the coronavirus pandemic, a new disease entity associated with a multisystem hyperinflammation syndrome as a result of a previous infection with the SARS-CoV-2 virus is increasingly being identified in children termed Multisystem Inflammatory Syndrome in Children (MIS-C) and more recently in adults(MIS-A). Due to its clinical similarity with Kawasaki Disease, some institutions have used intravenous immunoglobulins and steroids as first line agents in the management of the disease. We seek to find how effective intravenous immunoglobulin therapy is across these two disease entities. A comprehensive English literature search was conducted across PubMed, MEDLINE, and EMBASE databases using the keywords multisystem inflammatory syndrome in children/adults and treatment. All major online libraries concerning the diagnosis and treatment of MIS-C and MIS-A were searched. Relevant papers were read, reviewed, and analyzed. The use of intravenous immunoglobulins (IVIG) and steroids for the treatment of multisystemic inflammatory syndrome in children(MIS-C) is well established and recommended by multiple pediatric governing institutions. However, there is still no optimal treatment guideline or consensus on the use of IVIG in adults. The use of IVIG in both the child and adult populations may lower the risk of treatment failure and the need for adjunctive immunomodulatory therapy. Despite the promising results of IVIG use for the management of MIS-C and MIS-A, considering the pathophysiological differences between MIS-C and MIS-A, healthcare professionals need to further assess the differences in disease risk and treatment. The optimal dose, frequency, and duration of treatment are still unknown, more research is needed to establish treatment guidelines.

Feasibility and Safety of 5G-Based Telerobotic Abdominal Ultrasonography.

OBJECTIVE: Telemedicine can offer services to remote patients regardless of the distance. Fifth-generation (5G) mobile networks may make telemedicine practical because of their low latency. This study aimed to evaluate the feasibility and safety of a novel 5G robot-assisted remote abdominal ultrasound (AUS) telemedicine technology in clinical applications in distant locations. METHODS: We performed 5G-based telerobotic AUS in patients who were located more than 100 km away from the physicians. RESULTS: The telerobotic AUS had a longer examination time than the conditional bedside AUS; however, the complete examination rate was not inferior. None of the volunteers experienced discomfort during the examination and the examination time was acceptable for all. CONCLUSION: Our findings confirm the feasibility and safety of 5G-based telerobotic AUS in clinical practice.

A pilot study of non-invasive diagnostic tools to detect Helicobacter pylori infection and peptic ulcer disease.

Helicobacter pylori (H. pylori) infection can lead to various digestive system diseases, making accurate diagnosis crucial. However, not all available tests are equally non-invasive and sensitive. This study aimed to compare the efficacy of non-invasive and invasive diagnostic tools for H. pylori infection and assess their correlation with esophagogastroduodenoscopic (EGD) findings. The study utilized the Campylobacter-Like Organism (CLO) test, serum anti-HP IgG blood test, and C-13-urea breath test (UBT) to diagnose H. pylori infection. A total of 100 patients with peptic ulcer symptoms, including 45 males and 55 females, were recruited for the study. Symptomatic patients between the ages of 20-70, eligible for EGD examination, were enrolled. Each diagnostic test and any combination of two positive tests were considered the reference standard and compared against the other diagnostic methods. Additionally, the relationship between these diagnostic tests and EGD findings was evaluated. Among the participants, 74.0% were diagnosed with peptic ulcer disease through EGD. The UBT demonstrated the highest Youden's index, ranging from 58 to 100%, against all the non-invasive tests. The IgG blood test displayed the highest sensitivity at 100%, with a specificity of 60-70%. On the other hand, the CLO test exhibited the highest specificity at 100% and a sensitivity of 50-85%. Furthermore, only the CLO test showed a significant association with esophageal ulcers (p-value = 0.01). The IgG blood test holds promise as a primary screening tool due to its exceptional sensitivity. While the UBT is relatively expensive, its non-invasive nature and high sensitivity and specificity make it a potential standalone diagnostic test for H. pylori infection. Moreover, the noteworthy negative correlation between the CLO test and esophageal ulcers provides evidence of the differing effects of H. pylori infection on antral-predominant and corpus-predominant gastritis.

Sulfur-Containing Amino Acids, Hydrogen Sulfide, and Sulfur Compounds on Kidney Health and Disease.

Hydrogen sulfide (H2S) plays a decisive role in kidney health and disease. H2S can ben synthesized via enzymatic and non-enzymatic pathways, as well as gut microbial origins. Kidney disease can originate in early life induced by various maternal insults throughout the process, namely renal programming. Sulfur-containing amino acids and sulfate are essential in normal pregnancy and fetal development. Dysregulated H2S signaling behind renal programming is linked to deficient nitric oxide, oxidative stress, the aberrant renin-angiotensin-aldosterone system, and gut microbiota dysbiosis. In animal models of renal programming, treatment with sulfur-containing amino acids, N-acetylcysteine, H2S donors, and organosulfur compounds during gestation and lactation could improve offspring's renal outcomes. In this review, we summarize current knowledge regarding sulfide/sulfate implicated in pregnancy and kidney development, current evidence supporting the interactions between H2S signaling and underlying mechanisms of renal programming, and recent advances in the beneficial actions of sulfide-related interventions on the prevention of kidney disease. Modifying H2S signaling is the novel therapeutic and preventive approach to reduce the global burden of kidney disease; however, more work is required to translate this into clinical practice.

Metformin reduces hepatocellular carcinoma incidence after successful antiviral therapy in patients with diabetes and chronic hepatitis C in Taiwan.

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.

Risk stratification of hepatocellular carcinoma incidence using a fibrosis-4-based prediction model in patients with chronic hepatitis C receiving antiviral therapy: a nationwide real-world Taiwanese cohort study.

A total of 1,589 patients who had received interferon-based treatment were enrolled and analyzed for the risk of hepatocellular carcinoma (HCC) in a real-world nationwide Taiwanese chronic hepatitis C cohort (T-COACH). We aimed to stratify HCC risk by non-invasive fibrosis index-based risk model. Of 1589 patients, 1363 (85.8%) patients achieved sustained virological response (SVR). Patients with SVR had 1, 3, 5 and 10-year cumulative HCC incidence rates of 0.55%, 1.87%, 3.48% and 8.35%, respectively. A Cox proportional hazards model revealed that non-SVR (adjusted hazard ratio [aHR]: 1.92, 95% confidence interval [CI]: 1.19-3.12, p = 0.008), diabetes mellitus (aHR: 2.11, 95% CI: 1.25-3.55, p = 0.005), and fibrosis (FIB)-4 at the end of follow-up (EOF; aHR: 5.60, 95% CI: 2.97-10.57, p < 0.0001) were independent predictors of HCC. Risk score models based on the three predictors were developed to predict HCC according to aHR. In model 1, the 10-year cumulative incidence rates of HCC were 43.35% in patients at high risk (score 9-10), 25.48% in those at intermediate risk (score 6-8), and 4.06% in those at low risk (score 3-5) of HCC. In model 2, the 10-year cumulative incidence rates of HCC were 39.64% in patients at high risk (at least two risk predictors), 19.12% in those at intermediate risk (with one risk predictor), and 2.52% in those at low risk (without any risk predictors) of HCC. The FIB-4-based prediction model at EOF could help stratify the risk of HCC in patients with chronic hepatitis C after antiviral treatment.

Butyrate ameliorates maternal high-fat diet-induced fetal liver cellular apoptosis.

A maternal high-fat diet (HFD) can impact the offspring's development of liver steatosis, with fetal development in utero being a crucial period. Therefore, this study investigated the mechanism and whether butyrate can rescue liver injury caused by maternal HFD in the fetus. Pregnant female Sprague Dawley rats were randomly divided into two groups, prenatal HFD (58% fat) exposure or normal control diet (4.5% fat). The HFD group was fed an HFD 7 weeks before mating and during gestation until sacrifice at gestation 21 days. After confirmation of mating, the other HFD group was supplemented with sodium butyrate (HFSB). The results showed that maternal liver histology showed lipid accumulation with steatosis and shortened ileum villi in HFD, which was ameliorated in the HFSB group (P<0.05). There was increased fetal liver and ileum TUNEL staining and IL-6 expression with increased fetal liver TNF-α and malondialdehyde expression in the HFD group (P<0.05), which decreased in the HFSB group (P<0.05). The fetal liver expression of phospho-AKT/AKT and GPX1 decreased in the HFD group but increased in the HFSB group (P<0.05). In conclusion that oxidative stress with inflammation and apoptosis plays a vital role after maternal HFD in the fetus liver that can be ameliorated with butyrate supplementation.

A study on how using an interactive multimedia e-book improves teachers' ability to teach evidence-based medicine depending on their seniority.

BACKGROUND: Teaching evidence-based medicine (EBM) is not an easy task. The role of the electronic book (e-book) is a useful supplement to traditional methods for improving skills. Our aim is to use an interactive e-book or PowerPoint to evaluate instructors' teaching effects on EBM. METHODS: Our study group was introduced to learning EBM using an interactive e-book available on the Internet, while the control group used a PowerPoint presentation. We adopted the Modified Fresno test to assess EBM skills both before and after their learning. EBM teaching sessions via e-book or PowerPoint were 20-30 min long, followed by students' feedback. We adopted Student's t-test to compare teachers' evaluation of their EBM skills prior to the class and the students' assessment of the teachers' instruction. We also adopted repeated measures ANCOVA to compare teachers' evaluation of their EBM skills using the Fresno test both before and after the class. RESULTS: We observed no difference regarding EBM skills between the two groups prior to their experimental learning, which was assessed by the Modified Fresno test. After learning, physicians in the study group ranked higher in choosing a case to explain which kind of research design was used for the study type of the question and explaining their choice (P = 0.024) as assessed by the post-test to pre-test Fresno test. Teaching effect was better in the e-book group than in the control group for the items, "I am satisfied with this lesson," "The teaching was of high quality," "This was a good teaching method," and "It aroused my interest in EBM." However, no differences were observed between the two groups in physicians who had more than 10 years' experience. CONCLUSIONS: The use of interactive e-books in clinical teaching can enhance a teacher's EBM skills, though not in more senior physicians. This may suggest that teaching methodology and activities differ for teachers' varying years of experience.

Long-term outcome of liver complications in patients with chronic HBV/HCV co-infection after antiviral therapy: a real-world nationwide study on Taiwanese Chronic Hepatitis C Cohort (T-COACH).

BACKGROUND AND AIM: The long-term outcome of hepatitis B virus (HBV) infection among patients dually infected with HBV and hepatitis C virus (HCV) remains unclear. We aimed to investigate the long-term liver outcomes of HBV/HCV-coinfected patients after antiviral therapy. METHODS: A total of 11,359 chronically HCV-infected patients with interferon-based therapy were registered in a nationwide Taiwanese Chronic Hepatitis C Cohort. A propensity score matched (PSM) cohort of HCV mono-infected (n = 7020) and HBV/HCV (n = 702) co-infected patients by age, sex, and fibrosis was recruited for outcome analysis. The primary outcome was liver-related complications, including hepatocellular carcinoma (HCC) and liver decompensation during a mean follow-up period of 4.44 years. RESULTS: Among HBV/HCV co-infected patients, patients without HCV-SVR had a significantly higher 10-year cumulative incidence of major liver-related complications than those with HCV-SVR. However, among patients with HCV-SVR in the PSM cohort, the risk of major liver-related complications, both HCC and liver decompensation, did not differ between HBV/HCV co-infected and HCV mono-infected patients. Similar results were observed among those without HCV-SVR. A substantial lower risk of major liver-related complications was found in HBV/HCV co-infected patients with HCV SVR and subsequent anti-HBV nucleot(s)ide analogues treatment. Overall, factors associated with major liver-related complications included age ≥ 65 year-old, BMI ≥ 27 kg/m2, FIB-4 ≥ 3.25, eGFR < 60 ml/min/1.73 m2, and non-HCV SVR, but not HBV co-infection. CONCLUSION: Interferon-based therapy reduced the long-term risk of major liver-related complications among HBV/HCV co-infected patients, as among HCV mono-infected patients. Nevertheless, post-HCV-SVR surveillance for major liver-related complications is mandatory among those high-risk groups.

Music-Based Intervention Ameliorates Mecp2-Loss-Mediated Sociability Repression in Mice through the Prefrontal Cortex FNDC5/BDNF Pathway.

Patients with Rett syndrome (RTT) show severe difficulties with communication, social withdrawl, and learning. Music-based interventions improve social interaction, communication skills, eye contact, and physical skills and reduce seizure frequency in patients with RTT. This study aimed to investigate the mechanism by which music-based interventions compromise sociability impairments in mecp2 null/y mice as an experimental RTT model. Male mecp2 null/y mice and wild-type mice (24 days old) were randomly divided into control, noise, and music-based intervention groups. Mice were exposed to music or noise for 6 h/day for 3 consecutive weeks. Behavioral patterns, including anxiety, spontaneous exploration, and sociability, were characterized using open-field and three-chamber tests. BDNF, TrkB receptor motif, and FNDC5 expression in the prefrontal cortex (PFC), hippocampus, basal ganglia, and amygdala were probed using RT-PCR or immunoblotting. mecp2 null/y mice showed less locomotion in an open field than wild-type mice. The social novelty rather than the sociability of these animals increased following a music-based intervention, suggesting that music influenced the mecp2-deletion-induced social interaction repression rather than motor deficit. Mechanically, the loss of BDNF signaling in the prefrontal cortex and hippocampal regions, but not in the basal ganglia and amygdala, was compromised following the music-based intervention in mecp2 null/y mice, whereas TrkB signaling was not significantly changed in either region. FNDC5 expression in the prefrontal cortex region in mecp2 null/y mice also increased following the music-based intervention. Collective evidence reveals that music-based interventions improve mecp2-loss-induced social dysfunction. BDNF and FNDC5 signaling in the prefrontal cortex region mediates the music-based-intervention promotion of social interactions. This study gives new insight into the mechanisms underlying the improvement of social behaviors in mice suffering from experimental Rett syndrome following a music-based intervention.

Hepatitis C virus eradication decreases the risks of liver cirrhosis and cirrhosis-related complications (Taiwanese chronic hepatitis C cohort).

BACKGROUND AND AIM: It is currently unknown how hepatitis C virus (HCV) eradication with pegylated interferon and ribavirin (PR) therapy affects the incidence of new-onset liver cirrhosis (LC) in patients without cirrhosis and the incidence of decompensated liver disease (DLD) or hepatocellular carcinoma (HCC) in patients with cirrhosis. METHODS: Taiwanese chronic hepatitis C cohort (T-COACH) is a nationwide HCV registry cohort from 23 hospitals in Taiwan recruited between 2003 and 2015. This study enrolled 10 693 patients with chronic hepatitis C (CHC), linked to the Taiwan National Health Insurance Research Database, receiving PR therapy for at least 4 weeks for new-onset LC and liver-related complications (DLD or HCC). RESULTS: Of the 10 693 patients, 1372 (12.8%) patients had LC, and the mean age was 54.0 ± 11.4 years. The mean follow-up duration was 4.38 ± 2.79 years, with overall 46 798 person-years. The 10-year cumulative incidence rates of new-onset LC were 5.0% (95% confidence interval [CI]: 3.2-7.7) in patients without cirrhosis with a sustained virologic response (SVR) and 21.9% (95% CI: 13.4-32.4) in those without SVR (hazard ratio [HR]: 0.22, P < 0.001). The 10-year cumulative incidence rates of liver-related complications were 21.4% (95% CI: 11.1-37.2) in patients with cirrhosis with SVR and 47.0% (95% CI: 11.1-86.0) in those without SVR after adjustment for age, sex, and competing mortality (HR: 0.52, P < 0.001). CONCLUSIONS: Hepatitis C virus eradication with PR therapy decreased the incidence of new-onset LC in noncirrhotic patients and the incidence of liver-related complications in cirrhotic patients with CHC.

Long-term risk of end-stage renal diseases with maintenance dialysis among chronic hepatitis C patients after antiviral therapy in Taiwan.

BACKGROUND AND AIM: Chronic hepatitis C virus (HCV) infection is associated with impaired renal function. The aim of this study is to explore the risk of and factors associated with end-stage renal diseases (ESRD) under maintenance dialysis among HCV patients after anti-HCV therapy. METHODS: A total of 12 696 HCV-infected patients with interferon-based therapy, including 9679 (76.2%) achieving sustained virological response (SVR), were enrolled from 23 hospitals in Taiwan. RESULTS: During a mean follow-up period of 5.3 years (67 554 person-years), the annual incidence of 4.1/10 000 person-years, 4.0/10 000 and 4.7/10 000 person-years among SVR patients and non-SVR patients, respectively. History of diabetes and baseline estimated glomerular filtration rate < 60 mL/min/m2 , instead of SVR, were the significant risk factors for developing ESRD with maintenance dialysis after anti-HCV therapy (adjusted hazard ratio 7.75 and 9.78). CONCLUSION: Diabetes and baseline impaired renal function were strongly associated with progression to ESRD with maintenance dialysis among chronic HCV-infected patients after antiviral therapy.

Successful Antiviral Therapy Reduces Risk of Schizophrenia Among Chronic Hepatitis C Patients: A Nationwide Real-World Taiwanese Cohort (T-COACH).

BACKGROUND: Chronic hepatitis C (CHC) has been associated with major psychoses, and interferon (IFN)-based therapy may cause psychiatric sequelae. We aimed to evaluate the effects of sustained virological response (SVR) on the incidence of major psychoses in a nationwide Taiwanese CHC cohort. METHODS: Fifteen thousand eight hundred thirty-six CHC Taiwanese who received IFN-based therapy were enrolled between 2003 and 2015. Of those, 12 723 patients were linked to the National Health Insurance Research Databases for the incidence of major psychoses. Death before major psychoses was considered a competing risk. RESULTS: Twenty-four patients developed new-onset major psychoses during 67 554 person-years (3.6 per 10 000 person-years), including 16 affective psychoses, 7 schizophrenia, and 1 organic psychotic condition. The incidence of major psychoses and affective psychoses did not differ between the SVR and non-SVR groups. The 10-year cumulative incidence of schizophrenia were significantly higher in the non-SVR than in SVR patients (0.14% vs 0.04%, P = .036). Cox subdistribution hazards showed that SVR and older age were associated with a significantly lower risk of schizophrenia (hazard ratio = 0.18 and 0.17). Sustained virological response was associated with decreased incidence of schizophrenia and majorly observed among patients with age <45 (P = .02). CONCLUSIONS: Successful IFN-based therapy might reduce the incidence of schizophrenia among CHC patients, especially among younger patients.

Efficacy of telbivudine and entecavir against virus reactivation in HBeAg-patients undergoing chemotherapy.

The renal protective effect of telbivudine (LdT) was verified by a previous meta-analysis. It was left unclear, however if this effect offsets the associated risk of virological breakthrough in hepatitis B e-antigen-negative (HBeAg-) patients receiving chemotherapy (C/T).Records of 260 HBeAg-, non-cirrhotic cancer patients undergoing systemic C/T with prophylactic LdT or entecavir (ETV) were retrospectively investigated. The investigation was conducted 6 months after completion of C/T, patient death from cancer, or antiviral modification. Treatment duration, outcome, change of renal function, and reason for antiviral modification were analyzed. The primary endpoint was the occurrence of virological breakthrough during prophylaxis C/T and the change in renal function.Of the 126 HBeAg- patients treated with LdT, 3 (2.38%) experienced HBV virological breakthroughs, whereas none of the patients treated with ETV (P = .07) did. The estimated glomerular filtration rate for the patients treated with LdT was essentially unaltered, decreasing only slightly from 87.5 ±â€Š23.1 to 87.3 ±â€Š21.3 ml/minute/1.73 m (P = .55), while the rate for the ETV-treated patients was significantly lowered from 95.7 ±â€Š32.2 to 85.5 ±â€Š85.7 ml/minute/1.73 m (P = .0009).The absolute risk reduction ARR is 27.8% - 21.2% = 6.6%, comparing ETV with LdT for reduction of renal function impairment and the absolute risk increase for virological breakthrough during C/T, the absolute risk increase (ARI) is 2.38% - 0% = 2.38%. The overall likelihood of being helped over being harmed was 2.77. With careful selection of patients with the criteria of HBeAg-status and non-hematologic cancer, it is feasible that telbivudine raise lower probability of virological breakthroughs during prophylaxis treatment.

Sustained virological response to hepatitis C therapy does not decrease the incidence of systemic lupus erythematosus or rheumatoid arthritis.

In patients with chronic hepatitis C (CHC), the effects of baseline characteristics, virological profiles, and therapeutic outcome to pegylated interferon plus ribavirin (PR) therapy on autoimmune diseases are unknown. Taiwanese Chronic Hepatitis C Cohort is a nationwide hepatitis C virus registry cohort comprising 23 hospitals of Taiwan. A total of 12,770 CHC patients receiving PR therapy for at least 4 weeks between January 2003 and December 2015 were enrolled and their data were linked to the Taiwan National Health Insurance Research Database for studying the development of 10 autoimmune diseases. The mean follow-up duration was 5.3 ± 2.9 years with a total of 67,930 person-years, and the annual incidence of systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA) was 0.03%. Other autoimmune diseases were not assessable due to few events. Body mass index ≥24 kg/m2 was an independent predictor of the low incidence of SLE or RA (hazard ratio 0.40, 95% confidence interval 0.17-0.93, p = 0.034). A sustained virological response (SVR) to PR therapy was not associated with the low incidence of SLE or RA in any subgroup analysis. CHC patients achieving SVR to PR therapy did not exhibit an impact on the incidence of SLE or RA compared with non-SVR patients.

Extrahepatic Malignancy Among Patients With Chronic Hepatitis C After Antiviral Therapy: A Real-World Nationwide Study on Taiwanese Chronic Hepatitis C Cohort (T-COACH).

INTRODUCTION: Chronic hepatitis C virus (HCV) infection is associated with nonhepatocellular carcinoma malignancies. We aimed to evaluate whether achieving a sustained virological response (SVR, defined as HCV RNA seronegativity throughout posttreatment 24-week follow-up) could reduce the risk of non-hepatocellular carcinoma malignancy in a real-world nationwide Taiwanese Chronic Hepatitis C Cohort (T-COACH). METHODS: A total of 10,714 patients with chronic hepatitis C who had received interferon-based therapy (8,186 SVR and 2,528 non-SVR) enrolled in T-COACH and were linked to the National Cancer Registry database for the development of 12 extrahepatic malignancies, including those with potential associations with HCV and with the top-ranking incidence in Taiwan, over a median follow-up period was 3.79 years (range, 0-16.44 years). RESULTS: During the 44,354 person-years of follow-up, 324 (3.02%) patients developed extrahepatic malignancies, without a difference between patients with and without SVR (annual incidence: 0.69% vs 0.87%, respectively). Compared with patients with SVR, patients without SVR had a significantly higher risk of gastric cancer (0.10% vs 0.03% per person-year, P = 0.004) and non-Hodgkin lymphoma (NHL) (0.08% vs 0.03% per person-year, respectively, P = 0.03). When considering death as a competing risk, non-SVR was independently associated with gastric cancer (hazard ratio [HR]/95% confidence intervals [CIs]: 3.29/1.37-7.93, P = 0.008). When patients were stratified by age, the effect of SVR in reducing gastric cancer (HR/CI: 0.30/0.11-0.83) and NHL (HR/CI: 0.28/0.09-0.85) was noted only in patients aged <65 years but not those aged >65 years. DISCUSSION: HCV eradication reduced the risk of gastric cancer and NHL, in particular among younger patients, indicating that patients with chronic hepatitis C should be treated as early as possible.

A randomized trial comparing the efficacy of single-dose and double-dose administration of rectal indomethacin in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis.

BACKGROUND AND AIMS: The before-procedure or after-procedure rectal indomethacin administration was shown to be useful in preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis. We designed this prospective randomized study to compare the efficacy of single-dose and double-dose rectal indomethacin administration in preventing post-ERCP pancreatitis (PEP). METHODS: We enrolled patients who underwent the ERCP in Taipei Mackay Memorial Hospital from 2016 June to 2017 November. Patients were randomly assigned to 2 groups: single and double-dose groups. The primary endpoint was the frequency of post-ERCP pancreatitis. RESULTS: A total 162 patients participated in this study, and there were 87 patients randomly assigned to the single-dose group, and 75 patients were assigned to the double-dose group. In the high-risk patients, the incidence of PEP was lower in double-dose patients (4.8%) than the single-dose patients (9.5%), but there was no significant difference (P =.24). Difficult cannulation was the only 1 risk factor for PEP after rectal indomethacin treatment. CONCLUSIONS: Single-dose rectal indomethacin administration immediately after ERCP in general population is good enough to prevent PEP, but difficult cannulation could induce the PEP frequency up to 15.4% even under rectal indomethacin use.

The effectiveness of music therapy for individuals with Rett syndrome and their families.

BACKGROUND: Patients with Rett syndrome (RTT) present characteristic regression in communication and hand skills, which eventually leads to intellectual and physical disability. Moreover, caregivers of patients with RTT face stressors related to patients' medical and developmental concerns. Given the indications from case reports, this pilot study investigated the effectiveness of music therapy on RTT patients, as well as on parental stress for families of children with RTT. METHODS: Families in the study group were enrolled in a twice-weekly 120-minute music therapy program for 24 weeks (n = 11), whereas families in the control group did not receive music therapy (n = 12). Participants were administered the Vineland Adaptive Behavior Scales, Rett Syndrome Clinical Severity Scale, Rett Syndrome Motor Behavioral Assessment, and Parenting Stress Index for caregivers of RTT children before and after the music therapy program. RESULTS: Music therapy improved receptive language, verbal and non-verbal communication skills, and social interaction for RTT patients. In addition, purposeful hand function, breathing patterns, and eye contact were significantly improved. Of note, music therapy also decreased the frequency of epileptic seizures. Lastly, caregivers in the study group exhibited significantly lower stress following the program. CONCLUSION: The 24-week music therapy program was effective in improving social interaction, communication skills, eye contact, hand function, and reducing seizure frequency among RTT patients. Additionally, music therapy was effective in relieving parenting stress, which may help healthcare providers initiate early intervention strategies that can prevent parenting stress and reduce the risk of depression.

High percentage atypical hepatocellular carcinoma in chronic hepatitis B patients treated with nucleos(t)ide analogs.

Nucleos(t)ide analogs are used for preventing liver cirrhosis in chronic hepatitis B patients, but the risk factors of hepatocellular carcinoma (HCC) in these patients remain unclear. We designed this retrospective cohort study, the aim is to determine the risk factors for HCC development and its image presentation under nucleos(t)ide analogs treatment.In this study, patients were treated with lamivudine (LAM), entecavir 0.5 mg (ETV), or telbivudine (LdT), and followed-up for at least 2 years to detect HCC and its presentation. Assessment of the risk factors for HCC included age, sex, HBeAg, viral load, liver cirrhosis, current and previous medications, and liver function tests.Totally, 396 patients were recruited, and 18 patients developed HCC. The mean time from the treatment to HCC development was 28.5 ±â€Š16.7 months. The clinical characteristics in HCC and no-HCC groups showed significant differences among age (52.8 ±â€Š6.1 vs 47.1 ±â€Š12.6 years, P <.01), baseline alanine transaminase (ALT) levels (161.4 ±â€Š177.3 vs 361.7 ±â€Š496.3, P <.01), and baseline liver cirrhosis (72.2% vs 29.9%, P <.01). In patients aged ≥45 years, the hazard ratio of HCC was 10.2 and liver cirrhosis was 4.1. Majority of HCCs developed in the right liver (14/18), were single numbered (13/18), had tumor size about 1.9 ±â€Š0.7 cm, were classified as T1 (14/18, TNM staging), and the atypical image occupied 88% of the HCC cases.The patients aged ≧45 years on long-term nucleos(t)ide analog therapy, and with baseline liver cirrhosis were at a high risk of HCC. Regular alpha-fetoprotein (AFP) assessment and image study of these patients are the gold standards for early HCC detection in patients with high percentage atypical HCC appearances.
