Distal Mean Nocturnal Baseline Impedance Predicts Pathological Reflux of Isolated Laryngopharyngeal Reflux Symptoms.

Background/Aims: Diagnosis of isolated laryngopharyngeal reflux symptoms (ILPRS), ie, without concomitant typical reflux symptoms (CTRS), remains difficult. Mean nocturnal baseline impedance (MNBI) reflects impaired mucosal integrity. We determined whether esophageal MNBI could predict pathological esophagopharyngeal reflux (pH+) in patients with ILPRS. Methods: In this cross-sectional study conducted in Taiwan, non-erosive or low-grade esophagitis patients with predominant laryngopharyngeal reflux symptoms underwent combined hypopharyngeal multichannel intraluminal impedance-pH monitoring when off acid suppressants. Participants were divided into the ILPRS (n = 94) and CTRS (n = 63) groups. Asymptomatic subjects without esophagitis (n = 25) served as healthy controls. The MNBI values at 3 cm and 5 cm above the lower esophageal sphincter (LES) and the proximal esophagus were measured. Results: Distal but not proximal esophageal median MNBI values were significantly lower in patients with pH+ than in those with pH- (ILPRS in pH+ vs pH-: 1607 Ω vs 2709 Ω and 1885 Ω vs 2563 Ω at 3 cm and 5 cm above LES, respectively; CTRS in pH+ vs pH-: 1476 vs 2307 Ω and 1500 vs 2301 Ω at 3 cm and 5 cm above LES, respectively, P < 0.05 for all). No significant differences of any MNBI exist between any pH- subgroups and healthy controls. The areas under the receiver operating characteristic curve in the ILPRS group were 0.75 and 0.80, compared to the pH- subgroup and healthy controls (P < 0.001 for both), respectively. Interobserver reproducibility was good (Spearman correlation 0.93, P < 0.0001). Conclusion: Distal esophageal MNBI predicts pathological reflux in patients with ILPRS.

Validation of Pharyngeal Acid Reflux Episodes Using Hypopharyngeal Multichannel Intraluminal Impedance-pH.

Background/Aims: Hypopharyngeal multichannel intraluminal impedance-pH (HMII-pH) technology incorporating 2 trans-upper esophageal sphincter impedance channels has been developed to detect pharyngeal reflux. We used the HMII-pH technique to validate the candidate pharyngeal acid reflux (PAR) episodes based on the dual-pH tracings and determined the interobserver reproducibility. Methods: We conducted a cross-sectional study in tertiary centers in Taiwan. Ninety patients with suspected laryngopharyngeal reflux and 28 healthy volunteers underwent HMII-pH test when off acid suppressants. Candidate PAR episodes were characterized by pharyngeal pH drops of at least 2 units and reaching a nadir pH of 5 within 30 seconds during esophageal acidification. Two experts manually independently identified candidate PAR episodes based on the dual-pH tracings. By reviewing the HMII-pH tracings, HMII-pH-proven PAR episodes were subsequently confirmed. The consensus reviews of HMII-pH-proven PAR episodes were considered to be the reference standard diagnosis. The interobserver reproducibility was assessed. Results: A total of 105 candidate PAR episodes were identified. Among them 84 (80.0%; 95% CI, 71.0-87.0%) were HMII-pH-proven PAR episodes (82 in 16 patients and 2 in 1 healthy subject). Patients tended to have more HMII-pH-proven PAR episodes than healthy controls (median and percentile values [25th, 75th, and 95th percentiles]: 0 [0, 0, 3] vs 0 [0, 0, 0], P = 0.067). The concordance rate in diagnosing HMII-pH-proven PAR episodes between 2 independent observers was 92.2%. Conclusion: Our preliminary data showed that 80.0% (71.0-87.0%) of the proposed candidate PAR episodes were HMII-pH-proven PAR episodes, among which the interobserver reproducibility was good.

Clinical values of Barcelona Clinic Liver Cancer subgroup and up-to-7 criteria in intermediate stage hepatocellular carcinoma with transcatheter arterial chemoembolization.

BACKGROUND: Transarterial chemoembolization (TACE) is a recommended treatment for patients with intermediate stage hepatocellular carcinoma (HCC) but with variable treatment outcomes. AIM: To determine factors for predicting outcomes of TACE in patients with intermediate stage B HCC. METHODS: Patients with Barcelona Clinic Liver Cancer (BCLC) stage B HCC who underwent TACE as the primary treatment were enrolled at Taichung Veterans General Hospital from January 2005 to December 2009. Patients were assigned to either the objective responder (OR) group or the non-OR group according to mRECIST criteria. Clinical and radiological characteristics were compared between the 2 groups. The overall survival of enrolled subjects was analyzed. RESULTS: In 128 enrolled patients, 66 (51.6%) were in the OR group and 62 (48.4%) in the non-OR group. Compared with the non-OR group, the OR group had a significantly smaller HCC size (6.55 cm vs 9.50 cm, P = 0.001) and was within the up-to-7 criteria (50% vs 26.7%, P = 0.001). After multivariable analyses, these significant associations still existed. Overall survival rate of all the subjects averaged 20.65 ± 13.26 mo. The survival rate at 1-year was 64.8%, 2-year was 46.9%, and 3-year was 31.2%. For those patients with OR to TACE, smaller tumor size and within up-to-7 criteria were associated with significantly better overall survival. Those patients with subgroup B1 had the highest OR ratio (75%) and better overall survival (26.70 ± 12.07 mo) after TACE. CONCLUSION: BCLC stage B HCC patients with smaller tumor size or within up-to-7 criteria had better survival outcomes to TACE. BCLC stage B subgroup is useful to predict refractoriness to TACE.

Safety of Nonagenarians Receiving Therapeutic ERCP, Single Center Experience.

(1) Background: The complication rates for nonagenarians receiving therapeutic endoscopic retrograde cholangiopancreatography (ERCP) remain poorly understood. We aimed to determine whether nonagenarians were at an increased risk of ERCP-related complications. (2) Methods: We performed a retrospective study on therapeutic ERCP in nonagenarians from 2011 to 2016 at Taichung Veterans General Hospital. A control group comprising patients aged 65 to 89 years was used to compare demographic data and the outcomes of therapeutic ERCP with the nonagenarians. The risk factors for complications were determined by logistic regression model. (3) Results: There were 35 nonagenarians and 111 patients in the control group. Overall, complication rates were not statistically different between the two groups. However, advanced age was an independent predictor of complications in the multivariate analysis (odds ratio [OR] = 1.06; 95% confidence interval [CI] = 1.01-1.12; p = 0.049). End stage renal disease (ESRD) was another independent predictor of complications (OR = 4.87; 95% CI = 1.11-21.36; p = 0.036). Post-ERCP pancreatitis and bleeding were more common in ESRD patients than patients without ESRD. (4) Conclusions: Although nonagenarians receiving ERCP did not have more complications compared to elderly patients younger than 90 years, advanced age and comorbidity still affect the outcome of therapeutic ERCP in the elderly patients.

Impact of Helicobacter pylori eradication timing on the risk of thromboembolism events in patients with peptic ulcer disease: a population-based cohort study.

OBJECTIVES: To evaluate the impact of Helicobacter pylori eradication on venous thromboembolism (VTE) events, and the differences between early and late treatment timing. DESIGN: A population-based cohort study. SETTING: Taiwan's National Health Insurance Research Database. PARTICIPANTS: A total of 6736 patients who received H. pylori eradication therapy from 2000 to 2010 were identified. We randomly selected 26 944 subjects matching in gender, age and baseline year as comparison cohort. PRIMARY AND SECONDARY OUTCOME MEASURES: The incidence rate ratios of VTE in the H. pylori eradication cohorts to that of the control cohort were examined. Multivariable Cox proportional hazard regression analysis was used to estimate the relative HRs and 95% CI of VTE development. RESULTS: The total incidence rate of VTE was observed in the late H. pylori eradication cohort, the early H. pylori eradication cohort and the control cohort (15.2, 3.04 and 2.91 per 1000 person-years, respectively). An age-specific trend was found in the late H. pylori eradication cohort, with a greater rate of VTE in the 50-65 years and more than 65 years age groups (adjusted HR 5.44; 95% CI 4.21 to 7.03 and 3.13; 95% CI 2.46 to 3.99). With comorbidities, the late H. pylori eradication cohort seemed to have the highest VTE incidence rate and adjusted HR (4.48, 95% CI 3.78 to 5.30). CONCLUSIONS: Late H. pylori eradication was associated with a significantly increased risk of VTE, and there was a significantly greater risk of VTE in patients with female gender, age more than 50 years and with comorbidities.

Colorectal Cancer Risk in Women with Gynecologic Cancers-A Population Retrospective Cohort Study.

We conducted a retrospective cohort study to evaluate the subsequent colorectal cancer (CRC) risk for women with gynecologic malignancy using insurance claims data of Taiwan. We identified patients who survived cervical cancer (N = 25,370), endometrial cancer (N = 8149) and ovarian cancer (N = 7933) newly diagnosed from 1998 to 2010, and randomly selected comparisons (N = 165,808) without cancer, matched by age and diagnosis date. By the end of 2011, the incidence and hazard ratio (HR) of CRC were estimated. We found that CRC incidence rates were 1.26-, 2.20-, and 1.61-fold higher in women with cervical, endometrial and ovarian cancers, respectively, than in comparisons (1.09/1000 person-years). The CRC incidence increased with age. Higher adjusted HRs of CRC appeared within 3 years for women with endometrial and ovarian cancers, but not until the 4th to 7th years of follow up for cervical cancer survivals. Cancer treatments could reduce CRC risks, but not significantly. However, ovarian cancer patients receiving surgery alone had an incidence of 3.33/1000 person-years for CRC with an adjusted HR of 3.79 (95% CI 1.11-12.9) compared to patients without any treatment. In conclusion, gynecologic cancer patients are at an increased risk of developing CRC, sooner for those with endometrial or ovarian cancer than those with cervical cancer.

Impact of Overlapping Functional Gastrointestinal Disorders on the Quality of Life in Patients With Gastroesophageal Reflux Disease.

Gastroesophageal reflux disease (GERD) and functional gastrointestinal disorders (FGIDs), including irritable bowel syndrome and functional dyspepsia, are common afflictions within the general population. Both conditions have a considerable impact on the daily health related quality of life (HRQoL) of affected individuals. Risk factors surrounding any impaired HRQoL in patients with GERD involve those of younger age, obesity, an increase in reflux symptom frequency, and overlapping FGIDs. The risk factors for subjects experiencing an overlap in FGIDs and GERD involve those who are female, younger age, cigarette smoking, non-erosive reflux disease, more GERD symptoms, and psychological performances including anxiety, somatization, and more frequent healthcareseeking behavior. The overlap of GERD and FGIDs is associated with a worsening of both physical and mental health, an increase in bothersome symptoms, impaired functional capacity, and a higher likelihood of consulting a physician. Acid secretion suppressors could offer therapeutic efficacy to some patients experiencing overlapping GERD and FGIDs.

Duodenal major papilla morphology can affect biliary cannulation and complications during ERCP, an observational study.

BACKGROUND: We investigated whether duodenal major papilla morphology could be a risk factor for failure of selective biliary cannulation (SBC) and post endoscopic retrograde cholangiography and pancreatography (ERCP) complications. METHODS: A prospectively recorded database was reviewed retrospectively. Patients were included if they received therapeutic ERCP and had naïve major duodenal papilla. We used Haraldsson's classification for papilla morphology, as follows: Regular (Type 1), Small (Type 2), Protruding or Pendulous (Type 3) and Creased or Ridged (Type 4). Risk factors for failing SBC and post-ERCP complications were analyzed by multivariate analysis. RESULTS: A total of 286 cases were included. Age, gender, indications and therapeutic procedures were not different among the four types of papillae. The failure rates of SBC with Type 3 papilla and Type 4 papilla were 11.11% and 6.25%, respectively. In the multivariate analysis, Type 2 papilla (odd ratio 7.18, p = 0.045) and Type 3 papilla (odd ratio 7.44, p = 0.016) were associated with greater SBC failure compared with Type 1 papilla. Malignant obstruction compared to stone (odds ratio 4.45, p = 0.014) and age (odd ratio = 1.06, p = 0.010) were also risk factors for cannulation failure. Type 2 papilla was correlated with a higher rate of post-ERCP pancreatitis (20%, p = 0.020) compared to the other types of papilla However, papilla morphology was not a significant risk factor for any complications in the multivariate analysis. CONCLUSION: Small papilla and protruding or pendulous papilla are more difficult to cannulate compared to regular papilla. Small papilla is associated with a higher rate of post-ERCP pancreatitis.

Epiretinal Membrane Detection at the Ophthalmologist Level using Deep Learning of Optical Coherence Tomography.

PURPOSE: Previous deep learning studies on optical coherence tomography (OCT) mainly focused on diabetic retinopathy and age-related macular degeneration. We proposed a deep learning model that can identify epiretinal membrane (ERM) in OCT with ophthalmologist-level performance. DESIGN: Cross-sectional study. PARTICIPANTS: A total of 3,618 central fovea cross section OCT images from 1,475 eyes of 964 patients. METHODS: We retrospectively collected 7,652 OCT images from 1,197 patients. From these images, 2,171 were normal and 1,447 were ERM OCT. A total of 3,141 OCT images was used as training dataset and 477 images as testing dataset. DL algorithm was used to train the interpretation model. Diagnostic results by four board-certified non-retinal specialized ophthalmologists on the testing dataset were compared with those generated by the DL model. MAIN OUTCOME MEASURES: We calculated for the derived DL model the following characteristics: sensitivity, specificity, F1 score and area under curve (AUC) of the receiver operating characteristic (ROC) curve. These were calculated according to the gold standard results which were parallel diagnoses of the retinal specialist. Performance of the DL model was finally compared with that of non-retinal specialized ophthalmologists. RESULTS: Regarding the diagnosis of ERM in OCT images, the trained DL model had the following characteristics in performance: sensitivity: 98.7%, specificity: 98.0%, and F1 score: 0.945. The accuracy on the training dataset was 99.7% (95% CI: 99.4 - 99.9%), and for the testing dataset, diagnostic accuracy was 98.1% (95% CI: 96.5 - 99.1%). AUC of the ROC curve was 0.999. The DL model slightly outperformed the average non-retinal specialized ophthalmologists. CONCLUSIONS: An ophthalmologist-level DL model was built here to accurately identify ERM in OCT images. The performance of the model was slightly better than the average non-retinal specialized ophthalmologists. The derived model may play a role to assist clinicians to promote the efficiency and safety of healthcare in the future.

Therapeutic benefits of combined sorafenib for intermediate hepatocellular carcinoma unresponsive to transarterial chemoembolization in a Chinese population.

OBJECTIVE: Transarterial chemoembolization (TACE) is the treatment modality for intermediate, or Barcelona Clinic Liver Cancer stage B, hepatocellular carcinoma (HCC), but its beneficial effect on outcomes is still unsatisfactory. This study aimed to assess the outcomes of combined TACE and sorafenib for patients with intermediate HCC. METHODS: Patients with intermediate HCC who were receiving TACE alone (the monotherapy group), or combined TACE and sorafenib (the combined therapy group) from January 2013 to June 2018 were enrolled. RESULTS: Altogether 64 patients were enrolled, of whom 34 were assigned to the monotherapy group and 30 to the combined therapy group. A prolonged time-to-progression (TTP) (mean 14.46 mo vs 6.39 mo, P = 0.001) was noted in the combined therapy group compared with the monotherapy group. Overall survival (OS) (mean 18.96 mo vs15.44 mo, P = 1.000) between the two groups did not differ significantly. After adjustment, there were no significant differences in the 12-18 month mortality rate between the two groups. CONCLUSION: Patients with intermediate HCC receiving combined TACE and sorafenib had a better TTP, but not OS, than those receiving TACE alone.

The therapeutic benefits of combined sorafenib and transarterial chemoembolization for advanced hepatocellular carcinoma.

OBJECTIVE: Systemic therapy, such as sorafenib, has been used clinically to treat patients with advanced stage or Barcelona Clinic Liver Cancer staging system (BCLC) stage C hepatocellular carcinoma (HCC). The aim of the study was to evaluate the therapeutic benefit of combined sorafenib and transarterial chemoembolization (TACE) in this group of patients. METHODS: Data on patients with HCC at BCLC stage C from August 2012 to September 2017 were collected. Patients who were given sorafenib alone were classified as the monotherapy group and those taking sorafenib and TACE were classed as the combined therapy group. RESULTS: A total of 118 patients were enrolled. There were 65 and 53 patients in the monotherapy and the combined therapy group, respectively. The groups' general characteristics were similar. Compared with the monotherapy group the combined therapy group experienced prolonged time-to-progression (TTP) (mean 6.42 mo vs 3.63 mo, P = 0.003) and overall survival (OS) (mean 11.21 mo vs 5.98 mo, P = 0.001). A subgroup analysis found that patients with macroscopic vascular invasion (MVI) also had prolonged TTP and OS in the combined therapy group than the monotherapy group (mean TTP, 7.93 mo vs 3.43 mo, P = 0.007; mean OS, 13.41 mo vs 5.50 mo, P = 0.001), however, these significant differences did not exist for those with extrahepatic spread (EHS). CONCLUSION: Combined sorafenib and TACE therapy has significant better outcomes than sorafenib alone in patients with stage C HCC, particularly those with MVI.

A Strategic Imperative for Promoting Hospital Branding: Analysis of Outcome Indicators.

BACKGROUND: Optimizing the use of social media to promote hospital branding is important in the present digital era. In Taiwan, only 51.1% of hospitals have official Facebook fan pages. The numbers of likes for these hospitals are also relatively low. OBJECTIVE: Our objective was to establish a special branding team for social media operation, led by top administrators of our hospital. Here we present our strategic imperative for promoting hospital branding as well as an analysis of its effectiveness. METHODS: Led by top administrators, the branding team was formed by 11 divisions to create branding strategies. From 2016 to 2018, the team implemented action plans. All information unique to the hospital was posted on Facebook, as well as on the hospital's official website. To determine the plans' efficiencies, we obtained reference data from Google Analytics, and we compared Facebook Insights reports for 2016 with those for 2017 and 2018. RESULTS: One of the branding team's main missions was to establish branding strategies and to integrate segmental branding messages. In each quarter we regularly monitored a total of 52 action plan indicators, including those for process and outcome, and discussed the results at team meetings. We selected 4 main performance outcome indicators to reflect the effectiveness of the branding efforts. Compared with 2016, the numbers of likes posted on the Facebook fan page increased by 61.2% in 2017 and 116.2% in 2018. Similarly, visits to the hospital website increased by 4.8% in 2017 and 33.1% in 2018. Most Facebook fan page and website viewers were in 2 age groups: 25 to 34 years, and 35 to 44 years. Women constituted 60.42% (14,160/23,436) of Facebook fans and 59.39% (778,992/1,311,605) of website viewers. According to the Facebook Insights reports, the number of likes and post sharing both increased in 2017 and 2018, relative to 2016. Comment messages also increased from 2016 to 2018 (P=.02 for the trend). The most common theme of posts varied over time, from media reports in 2016, to innovative services in both 2017 and 2018. Likes for innovative services posts increased from 2016 through 2018 (P=.045 for the trend). By the end of 2018, we recorded 23,436 cumulative likes for posts, the highest number among medical centers in Taiwan. CONCLUSIONS: We achieved the largest number of Facebook fans among all medical centers in Taiwan. We would like to share our experience with other hospitals that might be interested in engaging in social media for future communications and interactions with their patients.

Distinct Physiological Characteristics of Isolated Laryngopharyngeal Reflux Symptoms.

BACKGROUND & AIMS: Patients with isolated laryngopharyngeal reflux symptoms (LPRS) defined as those without concomitant typical reflux symptoms (CTRS) are clinically challenging to manage due to unclear pathophysiology. We investigated esophageal physiology in patients with isolated LPRS and their response to proton-pump inhibitors (PPI) therapy. METHODS: This is a multi-center observational study conducted in referral hospitals in Taiwan. Patients with predominant LPRS, but without common non-reflux causes, underwent esophageal manometry, 24-hr ambulatory esophagopharyngeal pH testing, and Bernstein test, followed by a 12-week esomeprazole 40 mg twice-daily treatment. Participants with pathological reflux were divided into the isolated LPRS group (ie, LPRS without CTRS, n = 40) and the CTRS group (ie, LPRS with CTRS, n = 66). Participants without pathological reflux or esophagitis (n = 132) served as the nonreflux controls. RESULTS: The PPI-responsiveness was similar between the isolated LPRS group and CTRS group (63% vs 57%, P = .8), but lower in the nonreflux controls (32%, P = .005). Despite similar distal esophageal acid exposure time (P = .7) when compared to those with CTRS, the isolated LPRS group had a lower prevalence of both positive Bernstein test (P = .001) and ineffective esophageal motility disorder (P = .03), and fewer pharyngeal acid reflux episodes (P < .0001). CONCLUSIONS: Our findings indicate similar distal esophageal acid exposure and PPI-responsiveness between LPRS patients with and without CTRS. The lack of CTRS in the isolated LPRS group is likely due to esophageal acid hyposensitivity and fewer pharyngeal acid reflux episodes, thus implicating distinct pathophysiology of isolated LPRS from those with CTRS.

Sorafenib treatment on Chinese patients with advanced hepatocellular carcinoma: A study on prognostic factors of the viral and tumor status.

Sorafenib is of proven efficacy in treating patients of hepatocellular carcinoma (HCC). Our study was aimed to determine the factors influence the sorafenib efficacy.We evaluated data of HCC patients receiving sorafenib from June 2012 to October 2016. All HCC cases were of the Barcelona Clinic Liver Cancer (BCLC) classification stage C. The exclusion criteria: those of BCLC classification stage A or B, with the absence or co-infection of hepatitis B (HBV) and hepatitis C (HCV). The presence of HBV, HCV, macoscopic vascular invasion (MVI) or extrahepatic spread (EHS) was recorded for each patient. Time-to-progression (TTP) and overall survival (OS) were analyzed.Among a total of 90 HCC patients, 48 (53.3%) had HBV infection, 42 (46.7%) had HCV infection, 51 (56.7%) had MVI, and 39 (43.3%) had EHS. Patients with HCV infection showed better TTP and OS than those with HBV infection. Patients with EHS had a longer TTP and OS than those with MVI. For patients with HBV infection, those with EHS had a longer TTP (mean 4.60 vs 2.64 months, P = .002) and OS (mean 6.65 vs 4.53 months, P = .045) compared to those with MVI. Among those with MVI, patients with HBV infection had a poorer TTP (mean 2.64 vs 4.74 months, P = .019) and shorter OS (mean 4.53 vs 7.00 months, P = .059) compared to those with HCV infection.HCC patients with HCV infection or with the presence of EHS showed better sorafenib efficacy.

Acute pancreatitis risk after kidney transplantation: Propensity score matching analysis of a national cohort.

PURPOSE: Data for elucidating post-kidney transplantation (KT) acute pancreatitis (AP) risk are limited and no large-scale cohort study has investigated the impact of AP after KT. METHOD: Data from Taiwan National Health Insurance (NHI) Research Database (NHIRD) were calculated through the method of propensity score matching to compare the pancreatitis risk in patients with and without KT. RESULTS: The overall pancreatitis incidence rates were 1.71 and 0.61 per 1,000 person-years in the KT and non-KT groups, respectively and corresponding adjusted HR (aHR [95% CI]) for pancreatitis was 2.48 (1.51-4.09) in the KT group. In the multivariable model, AP risk was higher in transplant patients with alcohol-related illnesses (aHR: 3.78, 95% CI: 1.32-10.8), gall stone disease (aHR: 3.53, 95% CI: 1.48-8.44), or past history of pancreatitis (aHR: 10.3, 95% CI: 5.08-20.8). Of note, recurrent AP risk was significantly higher in the KT group (aHR: 8.19, 95% CI: 2.89-23.2). Patients with post-KT AP demonstrated shorter patient and allograft survival than did those without (both P < 0.001, respectively). CONCLUSION: In conclusion, KT recipients are very likely to be associated with AP. Moreover, their inferior outcomes are strongly associated with post-KT AP.

Association of virological breakthrough and clinical outcomes in entecavir-treated HBeAg-positive chronic hepatitis B.

BACKGROUND & AIMS: To evaluate virological breakthrough (VBT) and the risk of hepatocellular carcinoma (HCC) in HBeAg-positive chronic hepatitis B (CHB) patients receiving entecavir (ETV) treatment. METHODS: A retrospective cohort study was conducted in a tertiary referral hospital and a total of 228 HBeAg-positive CHB patients treated with ETV for more than 48 weeks were enrolled. Clinical outcome measures included HBeAg seroclearance, maintained virological response and the development of HCC. RESULTS: During a median follow-up period of 197 weeks, VBT developed in 26 (11.4%) patients (VBT group), and the other 202 patients without VBT (non-VBT group). The overall cumulative rate of HBeAg seroclearance in the VBT group and non-VBT group were 23.1% and 23.8%, 27.1% and 37.9%, 27.1% and 55.1%, 27.1% and 74.1%, 27.1% and 76.7% from week 48 to 240, respectively(p = 0.013). The cumulative probability of maintained virological responses from week 48 to 240 were 7.69% and 21.78%, 7.69% in the VBT groups and 36.85%, 7.69% and 51.68%, 7.69% and 64.97%, 7.69% and 72.1% in the non-VBT groups, respectively (p<0.001). In the multivariate analysis, age (p<0.001) and virological response at week 24 (p = 0.005) were independently associated with VBT. Cox regression analysis showed that cirrhosis had carried the highest risk for HCC (HR = 4.99, CI = 1.14-21.81, p = 0.033). Subgroup survival analysis by Kaplan-Meier method showed that patients with VBT had higher incidence of developing HCC than without VBT in cirrhotic patients (50% (95%CI = 1-99%) vs 9% (95% CI = 1-9%); p = 0.048). CONCLUSIONS: VBT was associated with adverse clinical outcomes, including a low probability of HBeAg seroclearance, failure to achieve maintained virological responses, and a risk of developing HCC. Patients, particularly with cirrhosis, who had experienced VBT during ETV treatment, more likely developed HCC.

Second Asian Consensus on Irritable Bowel Syndrome.

BACKGROUND/AIMS: There has been major progress in our understanding of the irritable bowel syndrome (IBS), and novel treatment classes have emerged. The Rome IV guidelines were published in 2016 and together with the growing body of Asian data on IBS, we felt it is timely to update the Asian IBS Consensus. METHODS: Key opinion leaders from Asian countries were organized into 4 teams to review 4 themes: symptoms and epidemiology, pathophysiology, diagnosis and investigations, and lifestyle modifications and treatments. The consensus development process was carried out by using a modified Delphi method. RESULTS: Thirty-seven statements were developed. Asian data substantiate the current global viewpoint that IBS is a disorder of gut-brain interaction. Socio-cultural and environmental factors in Asia appear to influence the greater overlap between IBS and upper gastrointestinal symptoms. New classes of treatments comprising low fermentable oligo-, di-, monosacharides, and polyols diet, probiotics, non-absorbable antibiotics, and secretagogues have good evidence base for their efficacy. CONCLUSIONS: Our consensus is that all patients with functional gastrointestinal disorders should be evaluated comprehensively with a view to holistic management. Physicians should be encouraged to take a positive attitude to the treatment outcomes for IBS patients.

Sorafenib-Related Adverse Events in Predicting the Early Radiologic Responses of Hepatocellular Carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) has a poor prognosis with low chemotherapeutic efficiency to medications except to sorafenib. Previous studies showed that adverse events (AEs) of sorafenib can predict therapy efficacy to HCC. The aim of the study is to evaluate the early efficacy and AEs of sorafenib therapy. METHODS: The database of HCC patients receiving sorafenib at Taichung Veterans General Hospital during the period from June 2012 to October 2016 was analyzed. All HCC cases were Barcelona Clinic Liver Cancer (BCLC) classification stage C. The early efficacy of sorafenib was classified according to the mRECIST criteria as either partial response (PR), stable disease (SD) or progressive disease (PD). Responses were recorded within 6 weeks after the start of sorafenib treatment. AEs were defined as the appearance of hand-foot skin reaction (HFSR), hypertension (HTN) and diarrhea. Exclusion criteria were poor performance status, poor drug compliance, discontinued follow-up or mortality occurring within 1 day after medication. RESULTS: From a total of 222 subjects, eight cases (3.6%) were classified as PR, 82 cases (36.9%) SD, and 132 cases (59.5%) PD. The PR group had the highest ratio of HFSR (62.4%) and hypertension (37.5%). Pooling cases of PR and SD together, the presence of HFSR adjusted odd ratio (aOR) 2.80, 95% confidence interval (CI) 1.52 - 5.16) and diarrhea (aOR 3.42, 95% CI 1.67 - 7.01) were good predictors of favorable responses to sorafenib therapy. CONCLUSIONS: HFSR and diarrhea are good predictors of early therapy efficacy to the sorafenib treatment.

Specific adverse events predict survival rates in a Chinese population diagnosed with hepatocellular carcinoma and treated with sorafenib.

Hepatocellular carcinoma (HCC) is associated with a poor prognosis and a low chemotherapeutic efficiency except for when sorafenib is administered. The aim of this study was to evaluate the efficacy and adverse events (AEs) of sorafenib therapy in a Chinese population diagnosed with HCC. METHOD: Data for the subjects with HCC receiving sorafenib at Taichung Veterans General Hospital from June 2012 to October 2016 were evaluated. All enrolled cases belonged to the HCC Barcelona Clinic Liver Cancer (BCLC) classification stage C. The AEs were defined as appearances of hand-foot syndrome reaction (HFSR), hypertension (HTN), or diarrhea. The exclusion criteria included a poor performance status, lack of compliance to drugs, and loss of follow-up within the following day. RESULTS: Of a total of 116 subjects enrolled, there were 43 (37.1%), 13 (11.2%), and 15 (12.9%) cases experiencing HFSR, HTN, and diarrhea, respectively. The cases with AE had both a longer time to progression (TTP) (HFSR 5.16 vs. 3.33 months, P = 0.003; HTN 6.62 vs. 3.68 months, P = 0.001; diarrhea 6.67 vs. 3.61 months, P = 0.001) and overall survival (OS) (HFSR 8.12 vs. 4.75 months, P = 0.001; HTN 9.08 vs. 5.61 months, P = 0.008; diarrhea 8.20 vs. 5.67 months, P = 0.042) than those without. More AEs were correlated with a longer TTP and OS. CONCLUSION: The appearance of sorafenib AEs, including HFSR, HTN, and diarrhea, can predict a positive therapy efficacy to HCC.

Predicting Gastrointestinal Bleeding Events from Multimodal In-Hospital Electronic Health Records Using Deep Fusion Networks.

Applying machine learning (ML) methods on electronic health records (EHRs) that accurately predict the occurrence of a variety of diseases or complications related to medications can contribute to improve healthcare quality. EHRs by nature contain multiple modalities of clinical data from heterogeneous sources that require proper fusion strategy. The deep neural network (DNN) approach, which possesses the ability to learn classification and feature representation, is well-suited to be employed in this context. In this study, we collect a large in-hospital EHR database to develop analytics in predicting 1-year gastrointestinal (GI) bleeding hospitalizations for patients taking anticoagulants or antiplatelet drugs. A total of 815,499 records (16,757 unique patients) are used in this study with three different available EHR modalities (disease diagnoses, medications usage, and laboratory testing measurements). We compare the performances of 4 deep multimodal fusion models and other ML approaches. NNs result in higher prediction performances compare to random forest (RF), gradient boosting decision tree (GBDT), and logistic regression (LR) approaches. We further demonstrate that deep multimodal NNs with early fusion can obtain the best GI bleeding predictive power (area under the receiver operator curve [AUROC] 0.876), which is significantly better than the HAS-BLED score (AUROC 0.668).
