Abstract
INTRODUCTION Guselkumab is a human monoclonal antibody against IL-23 used in the treatment of moderate-to-severe psoriasis. This post-hoc analysis evaluated the efficacy and safety of guselkumab in the Asian subpopulation of VOYAGE 1 and VOYAGE 2 through 5 years. METHODS The proportions of guselkumab-treated Asian patients (VOYAGE 1 and 2) achieving Psoriasis Area and Severity Index (PASI) 90 and PASI 100, Investigator's Global Assessment (IGA) scores of 0/1 and 0, and Dermatology Life Quality Index (DLQI) scores of 0/1 (week 100 through week 252) were assessed. Non-responders were patients who met the treatment failure rules. Efficacy endpoints were analyzed using the as-observed methodology (no missing data imputation) for both studies and using non-responder imputation (for patients with any missing data) in VOYAGE 1. Safety outcomes were based on pooled data through week 252. RESULTS Response rates through week 252 for 199 Asian patients in the guselkumab group in VOYAGE 1 and VOYAGE 2, respectively, were 76.8% and 80.6% (PASI 90), 26.8% and 38.7% (PASI 100), 64.3% and 87.1% (IGA 0/1), and 26.8% and 45.2% (IGA 0). DLQI (0/1) at week 252 was achieved by 52.7% of patients in VOYAGE 1 and 61.3% in VOYAGE 2, while DLQI (0) at week 252 was achieved by 32.7% of patients in VOYAGE 1 and 40.3% in VOYAGE 2. The safety profile was similar to the global population and remained consistent through 5 years. Asian patients were followed for a total of 814 patient-years (PY). Over 85% of the guselkumab-treated patients continued treatment through week 264. The rate of serious adverse events (AEs) at week 252 was 3.07/100 PY. Rates of AEs of interest were low: serious infections, 0.74/100 PY; nonmelanoma skin cancer (NMSC), no patients; malignancies other than NMSC, 0.12/100 PY; and no major adverse cardiovascular events (MACE). CONCLUSION These analyses confirm a continuous response over 5 years, indicating that guselkumab shows therapeutic longevity in Asian patients requiring long-term treatment for moderate-to-severe psoriasis. TRIAL REGISTRATION ClinicalTrials.gov identifiers: VOYAGE 1 [NCT02207231] and VOYAGE 2 [NCT02207244].

Abstract
The treatment responses and outcomes in patients with Mycobacterium avium-intracellulare complex pulmonary disease (MAC-PD) remain uncertain. This retrospective study was conducted in Taiwan between 2011 and 2020. A microbiological cure was defined as the requirement for a minimum of three consecutive negative cultures following culture conversion that continued until the completion of anti-MAC treatment. A total of 97 patients with MAC-PD were enrolled in this study. The sputum smear-negative conversion rate was 40% (19/47). Thirty (31%) patients achieved sputum culture-negative conversion rates within 3 years after treatment initiation. All patients with negative sputum culture conversion rates achieved microbiological cure. Patients treated with a macrolide + rifamycin + ethambutol (M + R + EMB)-based regimen had a higher microbiological cure rate than the other patients (39% vs 17%, P = 0.023). Patients with persistently positive sputum smears after 6 months of treatment had a lower microbiological cure rate than those with negative sputum smears (6% vs 44%, P < 0.001). Among 30 patients with microbiological cure, the median time from sputum culture conversion to treatment completion was 221.5 (0-483) days, and the 1-year relapse rate was 17%. Treatment with the M + R + EMB-based regimen was associated with a higher microbiological cure rate, and patients with persistently positive sputum smears after 6 months of treatment had a lower microbiological cure rate. IMPORTANCE The treatment responses and outcomes in patients with Mycobacterium avium-intracellulare complex pulmonary disease (MAC-PD) remain uncertain. In this study, patients with MAC-PD treated with a macrolide + rifamycin + ethambutol (M + R + EMB)-based regimen had a higher microbiological cure rate than those treated with other regimens. After 6 months of treatment, patients with persistently positive sputum smears had a lower microbiological cure rate than those with negative sputum smears. Among patients with microbiological cure, the median time from sputum culture conversion to treatment completion was 221.5 days (range, 0-483), and the 1-year relapse rate was 17%.

Abstract
Patients with psoriasis were randomized to guselkumab, placebo or adalimumab in the VOYAGE 1 and VOYAGE 2 studies. In this post hoc analysis, difficult-to-treat psoriasis regions in the Asian subpopulation for both the guselkumab and adalimumab groups were compared with placebo at week 16 and the active treatment groups were compared at week 24. Endpoints included patients achieving scores of 0 or 1 (clear or near clear) or 0 (clear) on the scalp-specific Investigator's Global Assessment (ss-IGA), Physician's Global Assessment of the hands and/or feet (hf-PGA), and fingernail PGA (f-PGA), and percentage improvement in target Nail Psoriasis Severity Index (NAPSI) score through week 24. Efficacy was also assessed by prior biologic experience at baseline. A total of 199 eligible Asian patients were included. The proportion of patients achieving "clear" or "near clear" with guselkumab was superior to adalimumab at week 24 for scalp psoriasis ss-IGA (Asian patients, 72 [85.7%] vs 35 [67.3%], P = 0.004), hands and/or feet psoriasis hf-PGA (29 [82.9%] vs 16 [61.5%], P = 0.054), and similar for fingernail psoriasis f-PGA (28 [63.6%] vs 17 [54.8%], P = 0.412). Guselkumab mean improvements in NAPSI were comparable to adalimumab (39.9% vs 35.9%, P = 0.618). Overall, the complete clearance response of scalp, and hands and/or feet at week 24 occurred in a greater proportion of patients in the guselkumab group, irrespective of baseline biologic status (treatment-naïve or treatment-experienced). Guselkumab was superior to adalimumab for the treatment of scalp, and hands and/or feet psoriasis, and proportionally higher for fingernail psoriasis. Findings were comparable to the global study population.

Abstract
Purpose
The purpose of this paper is to provide a cross-platform recommendation system that recommends the most suitable public Instagram accounts to Facebook users.
Design/methodology/approach
We collect data from both Facebook and Instagram and then propose a similarity matching mechanism for recommending the most appropriate Instagram accounts to Facebook users. By removing the data disparity between the two heterogeneous platforms and integrating them, the system is able to make more accurate recommendations.
Findings
The results show that the method proposed in this paper can recommend suitable public Instagram accounts to Facebook users with very high accuracy.
Originality/value
To the best of the authors’ knowledge, this is the first study to propose a recommender system to recommend Instagram public accounts to Facebook users. Second, our proposed method can integrate heterogeneous data from two different platforms to generate collaborative recommendations. Furthermore, our cross-platform system reveals an innovative concept of how multiple platforms can promote their respective platforms in a unified, cooperative and collaborative manner.

Abstract
This study aimed to investigate the characteristics of, exposure to, and factors influencing gas-phase and PM2.5-bound phthalates (PAEs) in nail salons. Data on both indoor and outdoor gas-phase and PM2.5-bound PAEs, carbon dioxide (CO2), temperature, and relative humidity were collected in nail salons. We also used questionnaires to survey building characteristics and occupants' behaviors. The average total gas-phase and PM2.5-bound PAE concentrations indoors were higher than those outdoors by 6 and 3 times, respectively. Diethyl phthalate, diisobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), and di-(2-ethylhexyl) phthalate (DEHP) were the predominant compounds among both the gas-phase and PM2.5-bound PAEs in indoor air. The volume of the salon's space or the difference of indoor and outdoor CO2 concentrations (dCO2) was significantly associated with indoor PAE concentrations. The ratios of PM2.5-bound to gas-phase PAEs, especially high-molecular-weight PAEs, were positively associated with the dCO2 concentrations. Higher ratios of indoor to outdoor PM2.5-bound DiBP, DnBP, and DEHP concentrations were discovered when more clients visited each day. Building characteristics, ventilation conditions, and occupants' activities have influences on the gas-phase and particle-phase PAEs. The study identifies the characteristics of gas-phase and PM2.5-bound PAEs in nail salons and their influencing factors.

Abstract
Objectives A definitive diagnosis of pulmonary sarcomatoid carcinoma cannot be made with small biopsies. In clinical practice, a diagnosis of advanced non-small-cell lung cancer with spindle cell and/or giant cell carcinoma (NSCLCsg), or possible sarcomatoid carcinoma, is acceptable. Therefore, we aimed to investigate the treatment patterns and outcomes of advanced NSCLCsg. Materials and methods Between 01 January 2012 and 01 April 2021, patients with pathologically proven advanced NSCLCsg were enrolled. The choice of treatment was based on clinician discretion. Results In all, 101 patients with advanced NSCLCsg were enrolled. In total, 77 (76.2%) patients received at least one line of systemic therapy; 44 patients (43.1%) had received platinum doublet chemotherapy; 27 (26.7%) patients had been treated with targeted therapies; and 23 patients (22.8%) had been given an immune checkpoint inhibitor (ICI). The median overall survival (OS) was 6.3 months [95% confidence interval (CI): 3.6-9.0 months]. Excluding patients without systemic therapy, patients who had received an ICI had better OS (median: 18.2 months) than those who had not (median 3.8 months, log-rank test p = 0.002). No significant difference in OS was detected between patients who had or had not received platinum doublet chemotherapy (log-rank test p = 0.279), or targeted therapy (log-rank test p = 0.416). Having received any systemic therapy [hazard ratio (HR): 0.33, 95% CI: 0.18-0.61, p < 0.0001) and ICI (HR: 0.38, 95% CI: 0.19-0.78, p = 0.008) were independent factors for better OS. Patients with programmed death ligand-1 (PD-L1) expression ⩾50% had better OS than those with PD-L1 expression <50% (HR: 0.51, 95%: 0.30-0.86, p = 0.012). Conclusion Although advanced NSCLCsg has a poor survival outcome, our results showed that ICI may prolong OS in patients with advanced NSCLCsg. Further prospective studies are warranted to gain more understanding of the role of ICI in this specific patient population.

Abstract
Blood culture is the main tool used to identify causative pathogens. Adequate volume and number of culture sets are considered key to blood culture positivity rate. It is not known whether these factors remain critical to the positivity rate after the introduction of automated continuous blood culture system monitoring. We measured blood volume per bottle and described the distribution of blood volume and number of culture sets. Multivariate logistic regression was performed to determine the independent association of blood volume, number of culture sets, diagnosis of sepsis in a patient, and other covariates with blood culture results. Only 6.9% of the blood culture bottle volumes complied with the guidance (8-10 mL), with the highest culture positivity rate (18%). Of the culture events, only one set of blood was cultured in 60.9% of events. In the multivariate analysis, blood culture volume per event (odds ratio [OR], 1.09 [95% confidence interval [CI], 1.06-1.11]), patients with a diagnosis of sepsis (OR, 2.86 [95% CI, 2.06-3.98]), and samples from the emergency department (OR, 2.29 [95% CI, 1.72-3.04]), but not the number of culture sets (OR, 0.74 [95% CI, 0.50-1.12]), were observed to be statistically significant with respect to blood culture positivity rate. Our results revealed that the total blood culture volume and the diagnosis of sepsis were critical factors affecting blood culture positivity rate. However, the proportion of blood culture bottles with the optimal blood volume was very low, and optimizing blood volume would be key to increasing blood culture positivity rate.

Abstract
BACKGROUND Nickel, the fifth most common element on Earth, is the leading inducer of contact allergies in humans, with potent immunological effects. Nickel-induced contact allergies predominantly affect females. Maternal exposure to nickel has been associated with several developmental abnormalities. However, how a maternal nickel exposure affects the development of atopic diathesis and immune abnormalities in children has never been addressed. OBJECTIVES We aimed to determine whether maternal Ni exposure affects the development of atopic dermatitis and immune abnormalities in their children. METHODS Using a birth cohort study, we analysed 140 mother-child pairs recruited in 2012-2015 from central Taiwan. Maternal exposure to nickel was estimated using urinary nickel levels measured by inductively coupled plasma mass spectrometry (ICP-MS). The serum levels of 65 analytes and IgE in 3-year-old children were profiled with a multiplex ELISA. The correlation between the maternal urinary nickel concentration and serum analyte levels was assessed using Spearmen's correlation. Multivariant regression analysis was performed to evaluate the association between maternal urinary nickel levels and serum analyte concentrations in their children. RESULTS The geometric means of the maternal urinary nickel and the children's serum IgE levels were 2.27 μg/L and 69.71 IU/ml, respectively. The maternal nickel exposure was associated with increased serum levels of IL-1β, IL-2, TNF-α, and leukaemia inhibitory factor (LIF) but with decreased serum levels of matrix metalloproteinase-1 (MMP-1), IL-2R, and eotaxin-1 in the children. In addition, the development of childhood atopic dermatitis at 3 years old was significantly associated with the child's serum levels of IgE and IL-2R, but it was negatively associated with the maternal nickel exposure. CONCLUSIONS This is the first study showing the potential immunological effects of maternal nickel exposure in their children at an early developmental stage.

Abstract
Background: Biologics are used to treat moderate-to-severe psoriasis, and persistence to biologics may reflect clinical effectiveness. Limited information describing how biologics are used in patients with moderate-to-severe psoriasis in Asian countries is available. We conducted a population-based, retrospective, new user cohort study using the National Health Insurance Research Database (NHIRD) in Taiwan to assess treatment persistence and adherence to biologics. Methods: Adults with a diagnosis of psoriasis between 01 January 2015 and 31 December 2017 were identified in the NHIRD (ICD-9-CM 696.1; ICD-10 L40.0). New users were patients who initiated treatment with etanercept, adalimumab, ustekinumab or secukinumab between 01 January 2015 and 31 December 2017. All eligible patients were followed until 31 December 2018, death or disenrollment. Kaplan-Meier analysis was conducted to estimate persistence of treatment for index biologics. A Cox-proportional hazard regression model was used to compare risks of biologic discontinuation between biologic groups. Adjustments for potential confounding factors (age, gender and Charlson comorbidity index score) were made in the Cox model. Results: There were 1,397 new biologic users with psoriasis during the study period. The ratio men:women was approximately 4:1. Mean age of patients ranged from 44.6 to 47.7 years across exposure groups. The 1-year/2-years persistence rates were 94.2%/84.9% for ustekinumab, 96.2%/not calculated (due to too few patients at year 2) for secukinumab, 66.0%/29.9% for etanercept, and 59.8%/40.3% for adalimumab. The risk of discontinuation was significantly lower in patients initiating ustekinumab compared with adalimumab (hazard ratio adjusted for age, sex and co-morbidities 0.289, 95%CI 0.247-0.339, p < 0.0001). Drug survival was significantly higher for ustekinumab compared with adalimumab and etanercept (log-rank test p < 0.0001). The proportions of patients with 1-year/2-years medication possession ratios of ≥80% were 95.3%/92.0% for ustekinumab, 98.1%/not calculated for secukinumab, 89.4%/83.1% for etanercept, and 70.8%/59.4% for adalimumab. Limitations: Clinical improvement and response to treatment data were not available. Conclusion: There was relatively high persistence amongst biologic users with psoriasis in Taiwan. There is a trend towards greater persistence of ustekinumab compared to other biologics, the magnitude of which depends on the treatment gap used for its calculation. This study provides real-world evidence that may facilitate optimal treatment choice.

Abstract
Purpose The patients with prolonged mechanical ventilation (PMV) have the risk of ineffective coughing and infection due to diaphragm weakness. This study aimed to explore the effect of abdominal weight training (AWT) intervention with/without cough machine (CM) assistance on lung function, respiratory muscle strength and cough ability in these patients. Methods Forty patients with PMV were randomly assigned to three groups: AWT group (n = 12), AWT + CM group (n = 14) and control group (n = 14). Change of maximum inspiratory pressure (MIP), Maximum expiratory pressure (MEP) and peak cough flow (PCF) between 1 day before and 2 weeks after the intervention were compared among these three groups. Results MIP before and after intervention in AWT group (30.50 ± 11.73 vs. 36.00 ± 10.79; p < 0.05) and AWT + CM group (29.8 ± 12.14 vs. 36.14 ± 10.42; p < 0.05) compared with control group (28.43 ± 9.74 vs 26.71 ± 10.77; p > 0.05) was significantly improved. MEP before and after intervention in AWT group (30.58 ± 15.19 vs. 41.50 ± 18.33; p < 0.05) and AWT + CM group (27.29 ± 12.76 vs 42.43 ± 16.96; p < 0.05) compared with control group (28.86 ± 10.25 vs. 29.57 ± 14.21; p > 0.05) was significantly improved. PCF before and after intervention in AWT group in AWT group (105.83 ± 16.21 vs. 114.17 ± 15.20; p < 0.05) and AWT + CM group (108.57 ± 18.85 vs. 131.79 ± 38.96; p < 0.05) compared to control group (108.57 ± 19.96 vs. 109.86 ± 17.44; p > 0.05) showed significant improvements. AWT + CM group had significantly greater improvements than control group in MIP and peak cough flow than control group (13.71 ± 11.28 vs 19.64 ± 29.90, p < 0.05). Conclusion AWT can significantly improve lung function, respiratory muscle strength, and cough ability in the PMV patients. AWT + CM can further improve their expiratory muscle strength and cough ability.

Abstract
BACKGROUND Primary and recurrent venous thromboembolism (VTE) commonly occur in patients with cancer. However, because of the National Health Insurance regulations, available dosage forms, and clinical conditions, the prescribed dose of rivaroxaban may not be consistent with its recommended dose. OBJECTIVE To evaluate the 6-month recurrence rate of VTE and safety of rivaroxaban for patients with cancer. METHODS Patients with new cancer diagnosis or recurrence from 2014 to 2018 who initiated rivaroxaban for VTE from January 2015 to January 2019 were included. We set the rivaroxaban initiation date as the index date and followed up the patients for 180 days. We collected information regarding the starting and maintenance dose/frequency and the treatment duration. The efficacy outcome was the recurrence of VTE within 180 days. The safety outcome included the major bleeding rate and clinically relevant nonmajor bleeding (CRNMB) rate. RESULTS Approximately, 46.2% of the 65 included patients received a standard starting dose, and 45% of patients received a maintenance dose above 15 mg (median: 23.9 and 13.1 mg per day, respectively). Two-thirds of the patients stopped treatment within 180 days. Recurrent VTE occurred in 2 (3.1%) patients within 6 months. The major bleeding rate was 7.7%, and the CRNMB rate was 3.1%. CONCLUSION AND RELEVANCE The 6-month recurrence rate of VTE and safety profile were similar between the lower and standard dose of rivaroxaban. This result may be applied to the institutions with dosage availability limited by formulary regulation and patients who cannot use full dose because of clinical considerations.

Abstract
There are currently no good indicators that can be used to predict the medical expenses of chronic obstructive pulmonary disease (COPD). This was a retrospective study that focused on the correlation between the age, dyspnoea, and airflow obstruction (ADO) index and the Charlson comorbidity index (CCI) on the medical burden in COPD patients, specifically, those of patients with complete ADO index and CCI data in our hospital from January 2015 to December 2016. Of the 396 patients with COPD who met the inclusion criteria, 382 (96.5%) were male, with an average age of 71.3 ± 8.4 years. Healthcare resource utilisation was positively correlated with the ADO index. A significant association was found between the ADO index and CCI of COPD patients (p < 0.001). In-hospitalization expenses were positively correlated with the CCI (p < 0.001). Under the same CCI, the higher the ADO score, the higher the hospitalisation expenses. The ADO quartiles were positively correlated with the number of hospitalisations (p < 0.001), hospitalisation days (p < 0.001), hospitalisation expenses (p = 0.03), and total medical expenses (p = 0.037). Findings from this study show that the ADO index can predict the medical burden of COPD.

Abstract
BACKGROUND Hepatitis B surface antigen (HBsAg) seroclearance is the most important milestone indicating favourable clinical outcomes in patients with chronic hepatitis B (CHB). However, it is difficult to achieve due to the impaired HBV-specific immunity, such as programmed cell death 1 (PD-1)-associated T cell exhaustion. We assessed soluble PD-1 (sPD-1) as a novel seromarker for predicting spontaneous HBsAg loss. METHODS Serial serum levels of sPD-1 were evaluated in 1046 untreated hepatitis B e antigen (HBeAg)-seronegative individuals who had achieved undetectable serum HBV DNA. Multiple regression analyses were applied to assess associations among baseline and subsequent sPD-1 levels, HBsAg decline during follow-up, and spontaneous HBsAg seroclearance. RESULTS A total of 390 individuals achieved spontaneous HBsAg seroclearance during 6464.4 person-years of follow-up. Baseline sPD-1 levels were inversely associated with baseline HBsAg levels (qHBsAg) as well as a greater decline in qHBsAg during follow-up. Incidence rates of HBsAg seroclearance were 11.5, 61.7, 96.7 and 151.0 per 1000 person-years for sPD-1 levels of ≥4000, 536-3999, 125-535 and <125 pg/mL, respectively (Ptrend < 0.0001). Compared with baseline sPD-1 levels ≥4000 pg/mL, the rate ratio (95% CI) of HBsAg seroclearance was 2.1 (1.1-3.9), 3.0 (1.6-5.5) and 5.1 (2.8-9.5), for baseline sPD-1 levels of 536-3999, 125-535 and <125 pg/mL, respectively, after adjustment for sex, age and serum alanine aminotransferase and HBsAg levels. CONCLUSION sPD-1 level is a novel marker which independently predicts spontaneous HBsAg seroclearance of HBeAg-negative inactive CHB patients with undetectable HBV DNA. (word count: 234, <250).

Abstract
Airborne microplastic particles (MPs) are emerging contaminants. Although some studies have investigated the characteristics of indoor MPs in homes or offices, information regarding MPs in nail salons with potentially higher MP pollution is unavailable. In this study, we collected indoor and outdoor air samples from nail salons to analyze the concentrations, physical characteristics, and polymers of MPs and further assessed the exposure through inhalation and influencing factors. Our data displayed that the average indoor MP concentration was 46 ± 55 MPs/m3. The estimated average annual exposure to indoor MPs was 67,567 ± 81,782 MPs/year. The predominant shape and size of indoor MPs were fragment and <50 μm, respectively. The predominant polymer in indoor air was acrylic (27%), followed by rubber (21%), and polyurethane (13%). Air conditioner, nail treatment, ceiling and flooring with plastic materials, and number of occupants were factors affecting indoor MP concentrations. We concluded that MP pollution was more severe in nail salons and the physical characteristics and polymer compositions differed between nail salons and other indoor spaces reported in other studies. Air conditioner usage induced higher MP emission, and higher MP concentrations were observed in nail salons with plastic ceiling and flooring or more occupants.

Abstract
Background Robot-assisted hand training has shown positive effects on promoting neuromuscular control. Since both robot-assisted therapy and task-oriented training are often used in post-stroke rehabilitation, we raised the question of whether two interventions engender differential effects in different domains. Methods The study was conducted using a randomized, two-period crossover design. Twenty-four chronic stroke survivors received a 12-session robot-assisted intervention followed by a 12-session task-oriented intervention or vice versa. A 1-month washout period between each intervention was implemented. Outcome measures were evaluated before the intervention, after the first 12-session intervention, and after the second 12-session intervention. Clinical assessments included Fugl-Meyer Assessment for Upper Extremity, Wolf Motor Function Test, Action Research Arm Test and Motor Activity Log. Results Our findings suggested that EMG-driven robot-assisted therapy was as effective as task-oriented training in terms of improving upper limbs functional performance in activity domain, and robot-assisted therapy was more effective in improving movement duration during functional tasks. Task-oriented training showed better improvement in body function domain and activity and participation domain, especially in improving spontaneous use of affected arm during daily activities. Conclusions Both intervention protocol had their own advantages in different domains, and robot-assisted therapy may save manpower and be considered as an alternative intervention to task-oriented training. Combining the two approaches could yield results greater than either alone, which awaits further study. Trial registration: ClinicalTrials.gov Identifier: NCT03624153.

Abstract
BACKGROUND Coprescription is a potential medical problem for older adults that could induce polypharmacy and subsequent complications. In Taiwan, Chinese herbal medicine (CHM) is popular among the older adults. Investigating the coprescription trends in Western medicine, CHM and dental medicine is important to avoid possible polypharmacy. METHODS We analyzed data from the Longitudinal Health Insurance Database 2000 (LHID 2000) in Taiwan. Patients ≥ 60 years old who received coprescription of Western medicine, CHM and drugs for dental care from 1997 to 2013 were included. The odds ratio (OR) and 95% confidence interval (95% CI) were estimated by a logistic regression model for evaluating the correlation between baseline characteristics and coprescription. RESULTS A total of 266,034 patients were included for the analysis. Most patients receiving coprescriptions lived in the northern Taiwan and with a monthly income lower than 20,000 new Taiwan dollars. The trends in older adults using Western medicine alone or CHM alone decreased over time, but the cohort using dental medicine alone had the opposite result. Decreased trends in coprescription with age were noted. The trends in the proportion of coprescription and the number of days of coprescription increased with the calendar year. Increased trends in the proportion of patients with coprescription were also found, except for the cohort of patients who used both Western medicine and CHM. Patients who were female, and aged 70-79 years were prone to receive coprescription. CONCLUSIONS Coprescription in older patients is not uncommon in Taiwan. Healthcare providers and policymakers should be aware of the complex coprescription pattern in the older adults.

Abstract
Abstract
Study question
Does the presence of smooth endoplasmic reticulum clusters (sERCs) in oocytes affect the human embryo ploidy?
Summary answer
The euploidy rate of embryos originating from sERCs + oocytes is lower
What is known already
While an expert panel strongly recommended that sERCs+ oocytes should not be inseminated, some normal healthy babies derived from sERCs+ oocytes have been reported. In previous studies have shown that declined fertilization rate and lower proportions of good quality embryos are found in oocytes showing sERCs. The updating findings of the molecular status of sERC+ oocytes elucidated the sERCs+ oocytes may have impaired chromosomal segregation ability. However, no study reveals the relation between sERCs and embryo ploidy.
Study design, size, duration
A retrospective study enrolled 129 preimplantation genetic testing (PGT) cycles from January 2017 to March 2020 at Chang Gung Memorial Hospital, Lonkou.
Participants/materials, setting, methods
ICSI fertilization rate, Day5 usable blastocyst rate (D5UBR), total usable blastocyst rate (TUBR), euploidy rate, mosaic rate, and aneuploidy rate are investigated between embryo originating from sERCs+ and sERCs- oocytes.
Main results and the role of chance
Although higher TBUR in blastocyst derived from sERCs+ oocytes than sERCs- group (73.7% vs. 62.5%) but accompanied lower euploidy rate (7% vs. 29%) and higher aneuploid rate (79% vs. 54%).
Limitations, reasons for caution
Limited sample size, need a large-scale study to confirm the conclusion. The live-birth rate per embryo transfer cycle was not included for analysis. As we did not perform polar body analysis, we cannot state for sure that embryonic aneuploidy was related to the oocyte.
Wider implications of the findings: This study demonstrates that embryos originating from sERCs+ oocytes have a lower euploidy rate.

Abstract
Introduction: Glioblastoma multiforme (GBM) is the most aggressive glioma, and its diffuse
nature makes resection of it difficult. Moreover, even with the
administration of postoperative radiotherapy and chemotherapy, prolonged
remission is often not achieved. Hence, innovative or alternative treatments
for GBM are urgently required. Traditional Chinese herbs and their
functional components have long been used in the treatment of various
cancers, including GBM. The current study investigated the antitumor
activity of Wedelia chinensis and its major functional
components, luteolin and apigenin, on GBM. Materials and Methods: MTT assay, Transwell migration assay, and flow cytometry analysis were
adopted to assess the cell viability, invasive capability, and cell cycle.
Immunofluorescence staining and Western blotting were used to detect the
expressions of apoptotic and autophagy-related signaling molecules. Results: The W. chinensis extract (WCE) significantly inhibited the
proliferation and invasive ability of both GBM8401 and U-87MG cells in a
dose-dependent manner. Moreover, differential effects of WCE on GBM8401 and
U-87MG cells were observed: WCE induced apoptosis in GBM8401 cells and
autophagy in U-87MG cells. Notably, WCE had significant effects in reducing
the cell survival and invasive capability of both GBM8401 and U-87MG cells
than the combination of luteolin and apigenin. Conclusions: Taken together, these findings indicate the potential of using WCE and the
combination of luteolin and apigenin for GBM treatment. However, further
investigations are warranted before considering recommending the clinical
use of WCE or the combination of luteolin and apigenin as the standard for
GBM treatment.

Abstract
Objectives: Chronic kidney disease (CKD) has emerged as a global health concern. Many studies have identified an association between hyperuricemia and CKD, and some studies have revealed that urate-lowering therapy (ULT) can attenuate CKD progression. However, only a few studies have explored the role of ULT in the prevention of new onset CKD. Methods: To compare the risk of incident CKD between users and nonusers of ULT in patients with gout, we conducted a 13-year population-based retrospective cohort study. Overall incidence of CKD was compared between 7126 ULT users and 7126 matched ULT nonusers. Results: The CKD incidence rate for both the users and nonusers of ULT was 1.7 per 100 person-years, after adjusting for sex, age, region of residence, comorbidities, and medications used. No significant difference in CKD risk (adjusted hazard ratio [aHR]: 0.97; 95% confidence interval [CI]: 0.88-1.07) was noted between the ULT users and nonusers. In the subgroup of patients with diabetes mellitus (DM) and without hypertension (HT), ULT tended to be associated with lower risk of incident CKD (aHR: 0.52; 0.95% CI: 0.28-0.97). Compared with the risk of new onset CKD in patients receiving xanthine oxidase inhibitors, those receiving uricosuric agents seemed to have a lower risk of developing CKD (aHR: 0.81, 95% CI: 0.67-0.99). Conclusion: This population-based cohort study indicated that ULT is not associated with lower risk of CKD development. However, in the subgroup of patients with DM and without HT, ULT is associated with significantly lower risk of incident CKD.

Abstract
Background: Thionamides have been extensively used to treat patients with hyperthyroidism worldwide. Recent pharmacovigilance studies have revealed a safety signal between carbimazole or methimazole and pancreatitis. The associated risk remains unclear. Methods: We identified patients with newly diagnosed acute pancreatitis from 2000 to 2013 as the case group from the Taiwan Longitudinal Health Insurance Database 2000, which contains data from 1996 to 2013. Each patient with acute pancreatitis was matched for age, sex, comorbidities, and cancer with four controls through propensity score matching. A total of 52 patients without matched controls were excluded. Sensitivity analyses including the 52 excluded patients were performed using a matching ratio of 1:2. Odds ratios (ORs) along with 95% confidence intervals (CIs) for the association were estimated using multivariate logistic regression. Results: We included 9204 and 36,816 patients in the case and control groups, respectively. The proportions of patients who had used thionamides, carbimazole, methimazole, and propylthiouracil were similar in these two groups. In addition, the adjusted OR (CI) for the association of acute pancreatitis with thionamides was 1.03 (0.86-1.24), with carbimazole it was 0.90 (0.63-1.30), with methimazole it was 1.05 (0.84-1.31), and with propylthiouracil it was 1.00 (0.74-1.34). The sensitivity analysis results were unchanged. Conclusions: We were unable to demonstrate an association between acute pancreatitis and usage of thionamides.

Abstract
Periodontitis is a multifactorial inflammatory disease that can cause tooth loss and contribute to systemic inflammation. It is suggested that periodontitis may be associated with the development of glaucoma. Based on data from Taiwan’s National Health Insurance Research Database, a retrospective cohort study was conducted to investigate the risk of developing glaucoma in patients with periodontitis. The periodontitis cohort consisted of newly diagnosed adult patients (n = 194,090, minimum age = 20 years) between 2000 and 2012. The comparison group included age-, gender-, and diagnosis date-matched people without periodontitis (n = 194,090, minimum age = 20 years). Incident glaucoma was monitored until the end of 2013. Hazard ratios (HRs) with confidence intervals (CIs) were established based on the Cox proportional hazard models. The risk of developing glaucoma was higher in patients with periodontitis than those without periodontitis (31.2 vs. 23.3 patients per 10,000 person-years, with an adjusted HR of 1.26 [95% CI 1.21–1.32]). A high risk was evident even after stratifying by age (adjusted HRs = 1.34 [1.26–1.44] for ages 20–49, 1.24 [1.13–1.36] for ages ≥ 65, and 1.20 [1.12–1.29] for ages 50–64 years), sex (adjusted HRs = 1.33 [1.24–1.41] and 1.21 [1.14–1.28] for men and women, respectively), presence of comorbidity (adjusted HRs = 1.38 [1.29–1.47] and 1.18 [1.12–1.25] for without and with comorbidity, respectively), and corticosteroid use (adjusted HRs = 1.27 [1.21–1.33] and 1.21 [1.08–1.35] for without and with corticosteroid use, respectively). Specifically, patients with periodontitis exhibited a significantly high risk of primary open-angle glaucoma (adjusted HR = 1.31 [1.21–1.32]) but not for primary closed-angle glaucoma (adjusted HR = 1.05 [0.94–1.17]). People with periodontitis are at a greater risk of glaucoma than individuals without periodontitis. Ocular health should be emphasized for such patients, and the underlying mechanisms need further investigation.

Abstract
Background Knee osteoarthritis (OA) is known to be a progressive degenerative disorder; however, recent evidence suggests that inflammatory mediators contribute to cartilage degradation. Studies have reported that N-acetylcysteine (NAC) had a promising effect on the reduction of the synthesis of proinflammatory and structural mediators by synovial cells. Given the lack of relevant clinical trials, we conducted this study to determine the relationship between NAC use and risk of knee OA. Methods We designed a retrospective cohort study from 2000 to 2013. Patients who received oral NAC over 28 days within 1 year after the first prescription were defined as the case group, whereas those without NAC use were considered as candidates of the control group. We adopted 1:4 propensity-score matching by age, sex, index year, and comorbidities to obtain the control group. The primary outcome was a new diagnosis of knee OA during the follow-up period. Results Our study sample comprised 12,928 people who used NAC and 51,715 NAC nonusers. NAC users had a significantly higher incidence of osteoarthritis (adjusted hazard ratio: 1.42, P < .001) than did NAC nonusers. Also, in analyses stratified by age group and sex, all subgroups exhibited a significantly higher incidence of knee osteoarthritis (P < .0001) among NAC users than among NAC nonusers. The use of oral NAC was associated with nearly four-fold increased the risk of knee OA in the young age group. Conclusions Long-term use of oral NAC is associated with a higher risk of knee OA.

Abstract
Background: This retrospective cohort study compared patient survival and technique survival between patients on continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD) using recent data at a single tertiary medical center in Taiwan. Methods: From medical records, we identified incident 459 CAPD patients and 266 APD patients on dialysis for at least 90 days and aged more than 18 years to estimate mortality and technique failure rates, and related hazard ratio (HR) and 95% confidence interval (CI) from 2007 to 2018. Results: There were more women (52.3%) in the CAPD group, whereas patients in the APD group were younger. Compared to CAPD patients, APD patients had a lower mortality rate (2.83 vs. 5.79 per 100 person-years) with an adjusted HR of 0.69 (95% CI = 0.47–1.02), and a lower technique failure rate (9.70 vs. 17.52 per 100 person-years) with an adjusted HR of 0.65 (95% CI = 0.51–0.83). Further subgroup analyses revealed that, compared to CAPD, APD was associated with a significant lower risk of technique failure in male patients, patients aged 50–65 years, diabetic patients, patients without cardiovascular disease (CVD), patients with higher peritoneal permeability, or patients initiating PD in an earlier era. Conclusions: The mortality risk was not significant between CAPD and APD patients. APD is associated with a lower risk of technique failure than CAPD, particularly for male patients, and patients aged 50–65 years, with diabetes, without CVD, with high or high average peritoneal permeability, or initiating PD in an earlier era.

Abstract
Sustainable reservoir watershed management is crucial to maintain a water supply system. The purpose of this study is to assess the pollution sources of the Bao-Shan Reservoir, which is an off-stream reservoir and is the study reservoir herein. Most water source of the Bao-Shan Reservoir is from the Shang-Ping Watershed. This study applies the EPA's Storm Water Management Model (SWMM) and the Vollenweider model (VM) to analyze the pollution hotspots in the reservoir watershed and the impact of the pollutions on the reservoir water quality. The results indicate that non-point source pollution is the main pollution in the Shang-Ping Watershed. The pollution hotspots are located in the sub-watersheds S1, S3, S4, and S5. These sub-watersheds have higher total phosphorus (TP) loads per unit area. In order to protect the water quality of the Bao-Shan Reservoir, this study suggests that the TP load entering the reservoir needs to be reduced by about 16% to 24%. The control of non-point source pollution needs to be preferentially implemented in the Shang-Ping Watershed. The analysis and discussion in this study are a useful reference for reservoir watershed management.

Abstract
UNLABELLED Using national insurance claims of Taiwan, we found that magnesium oxide (MgO) use is associated with an increased risk of hip fracture in the elderly. Further studies are warranted to explore the mechanisms associated with MgO use that lead to hip fracture. PURPOSE The purpose of this study was to investigate the association between MgO use and hip fracture risk in the elderly (age > 65 years). METHODS This nationwide population-based retrospective study was conducted from 1996 to 2013. Individuals with (n = 26,069) and without (n = 26,069) MgO use were enrolled after propensity score matching. Primary outcome was a hip fracture. After adjusting for age, sex, comorbidities, and medications, multivariate Cox proportional hazards regression models were used to calculate incidences and risk of hip fracture [hazard ratio (HR)]. RESULTS During the mean follow-up duration of 4.8 years in the MgO cohort and 5.7 years in the non-MgO cohort, respectively 1547 and 1107 cases developed a hip fracture. MgO use was identified as a risk factor for hip fracture in both univariate [crude HR, 1.68; 95% confidence interval (CI), 1.55-1.81; p < 0.001] and multivariate [adjusted HR (aHR), 1.66; 95% CI, 1.54-1.80; p < 0.001] Cox proportional hazards regression models. The cumulative incidence of hip fracture was significantly higher in the MgO cohort than in the non-MgO cohort (1.23 per 100 person-years vs. 0.74 per 100 person-years, logrank test, p < 0.001). CONCLUSION MgO use is an independent risk factor for hip fracture in the elderly.

Abstract
BACKGROUND We investigated whether the availability of a tap water supply system is associated with lowering the admission rate 30 days after burn injury. METHODS We analysed data from the Longitudinal Health Insurance Database 2000 from the National Health Research Institutes. It contains a random sample of 1,000,000 subjects out of 22 million beneficiaries of the National Health Insurance of Taiwan from 1996 to 2010. The included patients were diagnosed twice with burn injuries in local medical departments. The odds ratios and 95% confidence intervals were estimated by logistic regression model to evaluate the correlations of baseline characteristics and comorbidities. RESULTS A total of 5,996 patients were identified after 1:1 propensity score matching. They had similar basic characteristics. Ultimately, 96 patients in the case cohort (1.10 per 1,000 person-years) and 58 patients in the control cohort (0.66 per 1,000 person-years) were admitted 30 days after a burn injury (adjusted hazard ratio 1.67, 95% confidence interval 1.21-2.32). A lower incidence of admission because of burn injury was found in the control cohort (log-rank test, p = 0.019). The advantageous effect of a well-equipped tap water system on a lower admission rate in burn patients was independent of comorbidities. CONCLUSIONS The results of this study demonstrated the association between lowering the admission rate at 30 days in burn patients in Taiwan and using a well-equipped tap water system. It also could offer important information to the government for enhancing the availability of tap water system in those areas lack adequate tap water supply which is useful to protect burn patients from following admission.

Abstract
We present two prescriptions for broadband ($ {\sim} 77 - 252\;{\rm GHz} $), millimeter-wave antireflection coatings for cryogenic, sintered polycrystalline aluminum oxide optics: one for large-format (700 mm diameter) planar and plano-convex elements, the other for densely packed arrays of quasi-optical elements-in our case, 5 mm diameter half-spheres (called "lenslets"). The coatings comprise three layers of commercially available, polytetrafluoroethylene-based, dielectric sheet material. The lenslet coating is molded to fit the 150 mm diameter arrays directly, while the large-diameter lenses are coated using a tiled approach. We review the fabrication processes for both prescriptions, then discuss laboratory measurements of their transmittance and reflectance. In addition, we present the inferred refractive indices and loss tangents for the coating materials and the aluminum oxide substrate. We find that at 150 GHz and 300 K the large-format coating sample achieves $ (97 \pm 2)\% $ transmittance, and the lenslet coating sample achieves $ (94 \pm 3)\% $ transmittance.

Abstract
BACKGROUND The relationship between constipation and childhood nocturnal enuresis (NE) has been previously reported; however, this relationship remains controversial. The present study aimed to evaluate the association between constipation and childhood NE. METHODS Data from the Longitudinal Health Insurance Database 2000 (LHID 2000) of Taiwan National Health Insurance Research Database from 2000 to 2013 were collected. A total of 2286 children were enrolled in this study: a case group of 1143 children aged 5-18 years who were diagnosed with NE (NE group) and an age- and sex-matched control group of 1143 children without NE. Conditional logistic regression and odds ratio (OR) for NE were used to examine the association between constipation and childhood NE. RESULTS The prevalence of NE in the case group (NE group, aged 5-18 years) was 1.03% from 2000 to 2013. The NE group had a higher percentage of constipation in 1 year before the diagnosis of NE. After stratification for sex, both boys and girls with constipation had higher OR for NE. With stratification for age, children aged 5-12 and 7-12 years had a higher OR for NE. CONCLUSIONS Constipation is associated with childhood NE in Taiwan, particularly in children aged 5-7 and 7-12 years.

Abstract
BACKGROUND Babesia gibsoni (B. gibsoni) is an intraerythrocytic protozoan parasite of dogs that causes fever and hemolytic illness. A timely diagnosis is essential for the disease management. RESULTS Here, we report a QubeMDx PCR system which enables a rapid, sensitive and reliable diagnosis of B. gibsoni near the dog patient. Within 30 min, this diagnostic assay was able to detect as low as 0.002% parasitemia of the dog blood. Using clinical samples, this new assay was validated to demonstrate 100% agreement with real-time PCR. CONCLUSIONS This novel diagnostic method provides a reliable point-of-care test to assist in the identification of B. gibsoni.

Abstract
We report the first detection of gravitational lensing due to galaxy clusters using only the polarization of the cosmic microwave background (CMB). The lensing signal is obtained using a new estimator that extracts the lensing dipole signature from stacked images formed by rotating the cluster-centered Stokes QU map cutouts along the direction of the locally measured background CMB polarization gradient. Using data from the SPTpol 500 deg^{2} survey at the locations of roughly 18 000 clusters with richness λ≥10 from the Dark Energy Survey (DES) Year-3 full galaxy cluster catalog, we detect lensing at 4.8σ. The mean stacked mass of the selected sample is found to be (1.43±0.40)×10^{14}M_{⊙} which is in good agreement with optical weak lensing based estimates using DES data and CMB-lensing based estimates using SPTpol temperature data. This measurement is a key first step for cluster cosmology with future low-noise CMB surveys, like CMB-S4, for which CMB polarization will be the primary channel for cluster lensing measurements.

Abstract
SETTING Two tuberculosis (TB) reference laboratories in Myanmar. OBJECTIVES To determine the proportion of extensively drug-resistant TB (XDR-TB) cases among multidrug-resistant TB (MDR-TB) cases and the mutations that cause resistance to second-line drugs in Myanmar. DESIGN This was a cross-sectional, retrospective study. Multidrug-resistant Mycobacterium tuberculosis isolates were collected during 2015-2016. Phenotypic drug susceptibility testing (DST) was performed and drug-resistant mutations identified by sequencing. Genotypes were determined to explain relationships between drug resistance patterns and genotypes. RESULTS Of 89 MDR-TB isolates, 12 were XDR-TB and 24 were pre-XDR-TB, with 21 resistant to fluoroquinolones (FQs) and 3 to second-line injectable agents (SLIDs). High rates of cross-resistance among second-line drugs were observed. Correlations between phenotypic and molecular DST against FQs and SLIDs were 91% in both cases. The most frequent mutation in FQ-resistant isolates was D94G (8/21) in gyrA and A1401G (11/15) in rrs in those resistant to SLIDs. The dominant genotype was the Beijing type (76/89). CONCLUSION There were high proportions of XDR-TB and pre-XDR-TB among MDR-TB cases; cross-resistance among second-line drugs was high, with various types of genetic mutations. These data suggest that resistance to second-line anti-tuberculosis drugs should be monitored intensively, and molecular DST should be employed.

Abstract
BACKGROUND Juvenile idiopathic arthritis (JIA) has been categorized into seven different categories according to the International League of Associations for Rheumatology (ILAR) criteria. Enthesitis-related arthritis (ERA) was found to represent the largest category in a Taiwanese cohort study. The aim in this study was to compare the clinical characteristics, treatments, and outcomes of ERA in a single tertiary center in Taiwan, as compared to those of other categories of JIA. Furthermore, we determined patients' characteristics and risk factors that can help assess the outcomes in ERA. METHODS A retrospective chart review of all patients with JIA referred to a pediatric rheumatology clinic in the National Taiwan University Hospital between 1993 and 2018 were identified according to ILAR criteria. Outcomes were assessed based on the Wallace criteria to categorize patients into active and non-active, including inactive, remission on medication, and remission off medication, groups. A subset of samples was further tested by DNA sequencing to identify HLA-B27 subtypes. RESULTS One-hundred and eighty-three patients were included in the study, with a mean of 8 years' follow-up. ERA was the single largest category of JIA (39.9%); psoriasis and undifferentiated JIA were both the least common type (0.5%). ERA was male predominant (86%), had a late age of onset (11.0 ± 3.2 years), and the majority of ERA patients was HLA-B27-positive (97%). Of 25 HLA-B27-positive ERA patients checked by HLA-B27 sequencing, 23 were B*27:04 and 2 were B*27:05. ERA patients were significantly less likely to achieve non-active status compared to patients with persistent oligoarthritis (P = 0.036). In terms of treatment response to TNF-α inhibitors in methotrexate-refractory ERA, 26 patients remained active and only 11 patients (30%) achieved a non-active status. Sacroiliitis was a risk factor contributing to poorer treatment response in ERA (P = 0.006). CONCLUSION ERA represented the most common category of JIA in Taiwan. Those ERA patients with sacroiliitis were likely to have persistent active disease and may require a more aggressive treatment strategy to improve their outcomes.

Abstract
BACKGROUND Rice (Oryza sativa) is one of the main crops in the world, and more than 3.9 billion people will consume rice by 2025. Sterility significantly affects rice production and leads to yield defects. The undeveloped anthers or abnormal pollen represent serious defects in rice male sterility. Therefore, understanding the mechanism of male sterility is an important task. Here, we investigated a rice sterile mutant according to its developmental morphology and transcriptional profiles. RESULTS An untagged T-DNA insertional mutant showed defective pollen and abnormal anthers as compared with its semi-sterile mutant (sstl) progeny segregates. Transcriptomic analysis of sterile sstl-s revealed several biosynthesis pathways, such as downregulated cell wall, lipids, secondary metabolism, and starch synthesis. This downregulation is consistent with the morphological characterization of sstl-s anthers with irregular exine, absence of intine, no starch accumulation in pollen grains and no accumulated flavonoids in anthers. Moreover, defective microsporangia development led to abnormal anther locule and aborted microspores. The downregulated lipids, starch, and cell wall synthesis-related genes resulted in loss of fertility. CONCLUSIONS We illustrate the importance of microsporangia in the development of anthers and functional microspores. Abnormal development of pollen grains, pollen wall, anther locule, etc. result in severe yield reduction.

Abstract
For chronic hepatitis B patients, hepatitis B e antigen (HBeAg) seroclearance signals a transition from an immunologically active phase to an inactive carrier state with a reduction in hepatitis B virus (HBV) DNA levels and a reduced risk of hepatocellular carcinoma (HCC).1 Predictors of HBeAg seroclearance include lower HBV DNA levels, viral genotype, the precore mutation, and higher serum alanine aminotransferase (ALT) levels.2.

Abstract
BACKGROUND & AIMS Although a low level of hepatitis B surface antigen (HBsAg) is a marker of hepatitis B virus (HBV) seroclearance, additional biomarkers are needed for more accurate prediction. We investigated whether quantification of antibody against HBV core protein (anti-HBc) can identify patients with undetectable levels of HBV DNA and HBsAg seroclearance among those who were HBV e antigen (HBeAg)-seronegative. METHODS We performed a retrospective analysis of data from a community-based cohort of individuals (30-65 years old) in Taiwan who were HBsAg seropositive, anti-HCV negative, and free of cirrhosis and/or liver cancer, recruited from 1991 through 1992, and evaluated every 6-12 months until June 30, 2004. We measured levels of anti-HBc in blood samples from 2500 participants who were seronegative for HBeAg. The first date at which a sample tested negative for HBV DNA or HBsAg, and remained negative in subsequent tests, was designated as the date of spontaneous HBV DNA undetectability or HBsAg seroclearance. We calculated cumulative incidences of HBV DNA undetectability and HBsAg seroclearance; associations between level of anti-HBc and undetectability of HBV DNA or HBsAg seroclearance were estimated by Cox proportional hazard regression. The effects of time on the associations between level of anti-HBc and HBsAg seroclearance was assessed by the area under the receiver operating characteristic curve (AUROC) analysis. RESULTS After a 12-year follow-up period, higher proportions of subjects with levels of anti-HBc <3 log IU/mL had undetectable levels of HBV DNA (58%) and HBsAg seroclearance (53%) than subjects with higher levels of anti-HBc (29.6% and 19.8%, respectively) (P < .001). For subjects with levels of HBsAg <102 IU/mL and anti-HBc <3 log IU/mL, the adjusted rate ratio of HBV DNA undetectability was 16.45 (95% CI, 11.15-24.28) and of HBsAg seroclearance was 17.95 (95% CI, 12.49-25.81), compared to subjects with higher levels of HBsAg and anti-HBc. A model that included level of anti-HBc as a parameter identified subjects with HBsAg seroclearance within 10 years with an AUROC of 82%; this value was significantly higher than that from models that include only level of HBV DNA and HBsAg (P < .0001). CONCLUSIONS In a retrospective analysis of a large cohort of patients with chronic HBV infection in Taiwan, we associated levels of anti-HBc <3 log IU/mL with undetectable HBV DNA and HBsAg seroclearance occurred within 10 years; patients who also have levels of HBsAg <102 IU/mL have greater odds. Combining data on levels of HBsAg, HBV DNA, and anti-HBc is able to identify HBeAg-seronegative patients who can achieve HBsAg seroclearance with an AUROC value of 82%.

Abstract
Objectives Wisteria floribunda agglutinin-positive human Mac-2-binding protein (WFA+-M2BP) is a glycomarker. The present community-based long-term follow-up study repeatedly determined the serum WFA+-M2BP level and examined its short- and long-term associations with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC). Methods A total of 921 participants with antibodies against HCV seropositive, but seronegative for hepatitis B surface antigen were enrolled from seven townships in Taiwan during 1991–1992. The participants were regularly followed and their serum WFA+-M2BP levels were measured at baseline and follow-up. HCC was ascertained through active follow-up and computerized data linkage with the National Cancer Registration System until December 31, 2013. Cox proportional hazards and logistic regression models were applied to estimate the magnitude of associations between serum WFA+-M2BP levels and HCC. Results During a median follow-up of 21.7 years, 122 new-onset HCC cases were identified. Elevated serum WFA+-M2BP levels were associated with an increased risk of HCC (p < 0.001). Patients with increasing changes in serum WFA+-M2BP levels, relative to their baseline levels, had a 4.36-fold risk of HCC. The areas under receiver operating curves (AUROCs) of WFA+-M2BP for predicting HCC showed that the prediction efficacy was significantly higher while closer to HCC diagnosis (p = 0.024). The AUROC was 0.91 for predicting HCC within 1 year by including the predictors of age, sex, alanine aminotransferase, alpha-fetoprotein (AFP) and WFA+-M2BP. Conclusions Serum WFA+-M2BP level may elevate before HCC onset and is a short-term predictor of HCC among patients infected with HCV.

Abstract
Watershed models are important tools for predicting the possible change of watershed responses. Environmental models comprise the deterministic model and the probabilistic model. This study discusses the Hydrological Simulation Program Fortran (HSPF) and the Back-Propagation Neural Network (BPNN); these two models represent the deterministic model and the probabilistic model, respectively. As the properties of the two models are distinct, they have differing abilities to predict surface-runoff pollution. For the two models, the runoff simulation results are satisfactory. However, due to the limitation of the water quality monitoring records, pollution simulation is more difficult than runoff simulation. The results indicate that the prediction accuracy in the pollution simulation can be improved by adjusting the BPNN neurons. On the contrary, improving the prediction accuracy is limited by HSPF. Although the flexibility of BPNN is higher than HSPF, sufficient historical monitoring records are important for both of these models.

Abstract
BACKGROUND Asians, Pacific Islanders and Maori have significantly lower rates of venous thromboembolism (VTE) compared to Europeans, but its clinic implication regarding diagnosis and prevention is unclear. AIMS To investigate if ethnicity affects the yield of computed tomography pulmonary angiography (CTPA) and ultrasonography of the lower limbs. METHODS Data previously collected for 523 patients from another study were used to analyse the effect of ethnicity on the results of CTPA; 1587 consecutive ultrasonography of lower limbs was retrospectively analysed according to ethnicity. The Wells score was retrospectively calculated to determine the pretest probability of VTE. RESULTS The positive rates of CTPA were 23.3% for European patients and 9.3% for non-European patients. The rate ratio was 2.50 (confidence interval [CI] 1.27-4.95). European patients were 2.5 times more likely to have a positive scan result than non-Europeans, given same pretest probability. There was a larger difference among patients with low and moderate pretest probability with a rate ratio of 4.27 (CI 1.62-11.3). The positive rates of ultrasound scans (USS) among European patients were 16.6 and 9.0% for non-European patients. Rate ratio was 1.85 (CI 1.27-4.95). The difference was also more significant amongst patients with low and moderate pretest probability. The rate ratio was 2.31 (CI 1.38-3.86) for European patients compared to non-European patients. CONCLUSION Given the same pretest probability according to the Wells score, European patients had significantly higher positive rates of CTPA and ultrasonography of the lower limbs than non-European patients. Further prospective studies are required to confirm our findings and establish an appropriate pretest assessment tool for non-European patients.
