Abstract
BACKGROUND The comparison between prostaglandin E2 (PGE2) and oxytocin and for induction of labor (IOL) remains controversial. OBJECTIVE The present study aimed to determine the safety and efficacy of these two agents in IOL. SEARCH STRATEGY PubMed, Embase, Web of Science, Cochrane Library, and ClinicalTrials.gov. from the establishment of the database to April 23, 2023. SELECTION CRITERIA A search was conducted with keywords "labor, induction, prostaglandin E2/PGE2/dinoprostone, and oxytocin". Only randomized clinical trials comparing oxytocin and vaginal dinoprostone in women who were at least late preterm (gestational age [GA] ≥34 weeks), singleton pregnant, and had intact membranes were enrolled for further meta-analysis. DATA COLLECTION AND ANALYSIS We conducted both a descriptive analysis and a meta-analysis. In the meta-analysis, we utilized the Mantel-Haenszel random effects model to analyze dichotomous data, employing the relative risk (RR) as the effect measure along with 95% confidence intervals (CIs). The study quality was evaluated using Cochrane Collaboration's risk of bias assessment tool (RoB 2). A random-effects model was applied for the meta-analysis. MAIN RESULTS After screening 3303 articles from five databases, a total of nine randomized controlled studies composed of 1071 patients were included. Our analysis included 534 patients in the PGE2 group and 537 patients in the oxytocin group. The pooled estimate of vaginal deliveries following PGE2 induction stood at 84.2%, while after oxytocin induction, it was 79.8%. The meta-analysis showed no statistical difference between the two groups in terms of the rate of vaginal delivery (pooled RR, 1.05; 95% CI: 0.95-1.16; P value for Q, 0.001; I2 , 71.14%), cesarean section (pooled RR, 0.84; 95% CI: 0.52-1.35; P value for Q, 0.007; I2 , 61.69%) and induction-delivery interval (pooled standard mean difference, 0.09; 95% CI: -0.67 to 0.85; P value for Q, 0.000; I2 , 96.45%). Since the results for fetal distress and uterine hyperstimulation were consistent across all enrolled studies, no further meta-analysis was conducted. CONCLUSIONS When amalgamating the available literature, it implies that oxytocin was found to have similar effects as PGE2 on delivery outcomes and safety concerns in pregnant women with GA ≥36 weeks. Although the uterine cervix was unfavorable, both low and high doses of oxytocin were feasible for IOL.

Abstract
BACKGROUND Taiwan has insufficient nursing resources due to the high turnover rate of health care providers. Therefore, reducing the heavy workload of these employees is essential. Herein, speech transcription, which has various potential clinical applications, was employed for the documentation of nursing records. The requirement of including only one speaker per transcription facilitated data collection and system development. Moreover, authorization from patients was unnecessary. OBJECTIVE The aim of this study was to construct a speech recognition system for nursing records such that health care providers can complete nursing records without typing or with only a few edits. METHODS Nursing records in Taiwan are mainly written in Mandarin, with technical terms and abbreviations presented in both Mandarin and English. Therefore, the training set consisted of English code-switching information. Next, transfer learning (TL) and meta-TL (MTL) methods, which perform favorably in code-switching scenarios, were applied. RESULTS As of September 2021, the China Medical University Hospital Artificial Intelligence Speech (CMaiSpeech) data set was established by manually annotating approximately 100 hours of recordings from 525 speakers. The word error rate (WER) of the benchmark model of syllable-based TL was 29.54% in code-switching. The WER of the proposed model of syllable-based MTL was 22.20% in code-switching. The test set comprised 17,247 words. Moreover, in a clinical case, the proposed model of syllable-based MTL yielded a WER of 31.06% in code-switching. The clinical test set contained 1159 words. CONCLUSIONS This paper has two main contributions. First, the CMaiSpeech data set-a Mandarin-English corpus-has been established. Health care providers in Taiwan are often compelled to use a mixture of Mandarin and English in nursing records. Second, an automatic speech recognition system for nursing record document conversion was proposed. The proposed system can shorten the work handover time and further reduce the workload of health care providers.

Abstract
Abstract
Study question
Our Retrospective study is to investigate an end-to-end deep learning model in identifying ploidy status through raw time-lapse video.
Summary answer
Our deep learning model demonstrates a proof of concept and potential in recognizing the ploidy status.
What is known already
Since the time-lapse system has been introduced into the IVF lab, the relationship between morphogenetic and ploidy status has been often discussed. However, the result has not yet reached a united conclusion due to some limitations such as human labeling. Besides the statistical approach, deep learning models have been utilized for ploidy prediction. As such approaches are single image-based, the performance remains unpromising as previous statistical-based research. Therefore, in order to move further toward clinical application, better research design and approach are needed.
Study design, size, duration
A retrospective analysis of the time-lapse videos and chromosomal status from 690 biopsied blastocysts cultured in a time-lapse incubator (EmbryoScope+, Vitrolife) between January 2017 and August 2018 in the Lee Women’s Hospital were assessed. The ploidy status of the blastocyst was derived from the PGT-A using high-resolution next-generation sequencing (hr-NGS). Embryo videos were obtained after normal fertilization through the intracytoplasmic sperm injection or conventional insemination.
Participants/materials, setting, methods
By randomly dividing the data into 80% and 20%, we developed our deep learning model based on Two-Stream Inflated 3D ConvNets(I3D) network. This model was trained by the 80% time-lapse videos and the PGT-A result. The remaining 20% has been tested by feeding the time-lapse video as input and the PGT-A prediction as output. Ploidy status was classified as Group 1 (aneuploidy) and Group 2 (euploidy and mosaicism).
Main results and the role of chance
Time-lapse videos were divided into 3-time partitions: day 1, day 1 to 3, and day 1 to 5. Deep learning models have been fed by RGB and optical flow. Combining 3 different time partitions with RGB, optical flow, and fused result from RGB and optical flow, we received nine sets of test results. According to the results, the longest time partition with the fusion method has the highest AUC result as 0.74, which appeared higher than the other eight experimental settings with a maximum increase of 0.17.
Limitations, reasons for caution
The present study is retrospective and future prospective research would help us to identify more key factors and improve this model. In addition, expanding sample size combined with cross-centered validation will also be considered in our future approach.
Wider implications of the findings
Group 1 and Group 2 approach provided deselection of aneuploidy embryos, while future deep learning approaches toward high mosaicism, low mosaicism, and euploidy will be needed, in order to provide a better clinical application.

Abstract
BACKGROUND The main etiologies of hepatocellular carcinoma (HCC) were often hepatitis B virus (HBV) or C and alcohol, rarely autoimmune and biliary diseases. Nonalcoholic fatty liver disease (NAFLD) has been an emerging role that could lead to chronic liver disease, nonalcoholic steatohepatitis, cirrhosis, and eventually HCC in recent years. The aim of our study is to investigate and compare the clinical features of HCC in patients with NAFLD and HBV, including age, gender, cirrhosis, liver function tests, largest tumor size, and cancer stage at the time of diagnosis. The survival outcome was compared between the two groups and the significant predictors of mortality were also analyzed in all patients with HCC. METHODS Most patients with HCC were recruited from the database of Cancer Registries in Taipei City Hospital, Ren-Ai Branch, from 2011 to 2017; and the other patients consecutively from the HCC multidisciplinary conference between January 2018 and December 2019. NAFLD was defined as nonviral hepatitis B (negative HBsAg and either positive anti-HBs or negative anti-HBc), nonviral hepatitis C (negative antihepatitis C virus [HCV]), nonalcoholic (alcohol consumption of <30 g/d for men and <20 g/d for women) liver disease, or present or past histological or ultrasonographic evidence of fatty liver. Totally, 23 NAFLD-related and 156 HBV-related HCC patients were enrolled in our study for further analysis. RESULTS NAFLD-related HCC patients were significantly older (median age: 70.0 [61.0-79.0] years vs. 63.0 [56.0-72.0] years, p = 0.012) and heavier (median body mass index [BMI]: 26.6 [24.2-30] kg/m2 vs. 24.8 [22.0-27.1] kg/m2, p = 0.044) than those with HBV-related HCC. They were also more susceptible to diabetes mellitus (DM), and 60.9% (14 of 23) of them had this comorbidity compared with 29.5% (46 of 156) of those with HBV-related HCC (p = 0.003). Only 34.8% (8 of 23) and 71.2% (111 of 156) of patients with NAFLD- and HBV-related HCC were cirrhotic, respectively (p = 0.001). However, gender, tobacco use, international normalized ratio, albumin, creatinine, and cholesterol levels were not significantly different between the two groups. Tumor characteristics such as the Barcelona clinic liver cancer stage, largest tumor size, tumor number, extrahepatic metastasis, and treatment modalities had no significant difference between such groups.According to the Kaplan-Meier method analysis, the overall survival was not significantly different between these two patient groups (log-rank test, p = 0.101). To evaluate which patient group would lead to poor prognosis, we analyzed the survival of all patients through multivariate Cox proportional hazard regression after controlling other factors that may influence the hazard ratio. The analysis revealed that NAFLD and HBV infection as the cause of HCC are not risk factors of poor prognosis. CONCLUSION In conclusion, our study showed NAFLD-related HCC patients were older, heavier, and more had DM than HBV-related. In addition, more NAFLD-related HCC patients were noncirrhotic than HBV-related. The survival rate was similar between NAFLD and HBV-related HCC patients.

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease characterized by chronic mucosal inflammation of the colon, and the prevalence and incidence of UC have been steadily increasing in Taiwan. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of UC taking into account currently available evidence and the expert opinion of the committee. Accurate diagnosis of UC requires thorough clinical, endoscopic, and histological assessment and careful exclusion of differential diagnoses, particularly infectious colitis. The goals of UC therapy are to induce and maintain remission, reduce the risk of complications, and improve quality of life. As outlined in the recommended treatment algorithm, choice of treatment is dictated by severity, extent, and course of disease. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to immunosuppressive treatment, especially with steroids and biologic agents, and should be regularly monitored for reactivation of latent infection. These consensus statements are also based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of UC in Taiwan.

Abstract
Crohn's disease (CD) is a chronic relapsing and remitting inflammatory disease of the gastrointestinal tract. CD is rare in Taiwan and other Asian countries, but its prevalence and incidence have been steadily increasing. A steering committee was established by the Taiwan Society of Inflammatory Bowel Disease to formulate statements on the diagnosis and management of CD taking into account currently available evidence and the expert opinion of the committee. Thorough clinical, endoscopic, and histological assessments are required for accurate diagnosis of CD. Computed tomography and magnetic resonance imaging are complementary to endoscopic evaluation for disease staging and detecting complications. The goals of CD management are to induce and maintain remission, reduce the risk of complications, and improve quality of life. Corticosteroids are the mainstay for inducing re-mission. Immunomodulating and biologic therapies should be used to maintain remission. Patients should be evaluated for hepatitis B virus and tuberculosis infection prior to treatment and receive regular surveillance for cancer. These consensus statements are based on current local evidence with consideration of factors, and could be serve as concise and practical guidelines for supporting clinicians in the management of patients with CD in Taiwan.

Abstract
AIM: To elucidate the variety of ways early-stage hepatocellular carcinoma (HCC) can appear on magnetic resonance (MR) imaging by analyzing T1-weighted, T2-weighted, and gadolinium-enhanced dynamic studies.
METHODS: Seventy-three patients with well-differentiated HCC (wHCC) or dysplastic nodules were retrospectively identified from medical records, and new histological sections were prepared and reviewed. The tumor nodules were categorized into three groups: dysplastic nodule (DN), wHCC compatible with Edmondson-Steiner grade I HCC (w1-HCC), and wHCC compatible with Edmondson-Steiner grade II HCC (w2-HCC). The signal intensity on pre-contrast MR imaging and the enhancing pattern for each tumor were recorded and compared between the three tumor groups.
RESULTS: Among the 73 patients, 14 were diagnosed as having DN, 40 were diagnosed as having w1-HCC, and 19 were diagnosed as having w2-HCC. Hyperintensity measurements on T2-weighted axial images (T2WI) were statistically significant between DNs and wHCC (P = 0.006) and between DN and w1-HCC (P = 0.02). The other imaging features revealed no significant differences between DN and wHCC or between DN and w1-HCC. Hyperintensity on both T1W out-phase imaging (P = 0.007) and arterial enhancement on dynamic study (P = 0.005) showed statistically significant differences between w1-HCC and w2-HCC. The other imaging features revealed no significant differences between w1-HCC and w2-HCC.
CONCLUSION: In the follow-up for a cirrhotic nodule, increased signal intensity on T2WI may be a sign of malignant transformation. Furthermore, a noted loss of hyperintensity on T1WI and the detection of arterial enhancement might indicate further progression of the histological grade.

Abstract
BACKGROUND/AIMS Mild to moderate iron overload is common in chronic hepatitis C (CHC) and may influence the response to antiviral therapy. The aim of this study was to assess the association among serum iron indices, hepatic iron stores and sustained virological response (SVR) rates of combination therapy with peginterferon alfa and ribavirin in patients with CHC. METHODOLOGY A total of 36 CHC patients were treated with peginterferon and ribavirin for 6 months. The SVR was defined as undetectable hepatitis C virus RNA by qualitative assay 6 months after the end of therapy. The serum iron indices including ferritin, iron and transferrin saturation were measured. The hepatic iron deposition was graded on Perls' stain. RESULTS The SVR was obtained in 25/36 (69.44%) patients. The serum iron indices including transferrin saturation and ferritin were not significantly different between patients with the SVR and without. In multivariate logistic regression analysis, cirrhosis (P = 0.010, odds ratio = 0.020) and a positive hepatic iron stain (P = 0.046, odds ratio = 0.065) were both significantly independent predictors of non-SVR. CONCLUSIONS The findings suggest that the positive hepatic iron stain is an independent predictor of non-response to combination therapy with peginterferon alfa and ribavirin for patients with CHC. Liver cirrhosis also predicts non-responses to the combination therapy.

Abstract
AIM: To evaluate the association among hepatic fibrosis, serum iron indices, and hepatic iron stores in patients with Chronic Hepatitis C (CHC).
METHODS: Thirty-two CHC patients were included in our study. The histological degree of fibrosis and inflammation activity was assessed according to the Metavir system. The serum iron indices including ferritin, iron and transferrin saturation were measured. Hepatic iron deposition was graded by Perls’ stain.
RESULTS: The CHC patients with severe hepatic fibrosis (n = 16) were significantly older than CHC patients with mild fibrosis (n = 16) (P = 0.024). The serum iron indices, increased serum iron store and positive hepatic iron stain were not significantly different between the two groups. In multivariate logistic regression analysis, the age at biopsy was an independent predictor of severe hepatic fibrosis (Odds ratio = 1.312; P = 0.035). The positive hepatic iron stain was significantly associated with the values of alanine aminotransferase (ALT) (P = 0.017), ferritin (P = 0.008), serum iron (P = 0.019) and transferrin saturation (P = 0.003). The ferritin level showed significant correlation with the value of ALT (r = 0.531; P = 0.003), iron (r = 0.467; P = 0.011) and transferrin saturation (r = 0.556; P = 0.002).
CONCLUSION: Our findings suggest that the severity of hepatitis C virus (HCV)-related liver injury is associated with patient age at biopsy. Both serum iron indices and hepatic iron deposition show correlation with serum indices of chronic liver disease but are not related to grade and stage of liver histology.

Abstract
A case of spontaneous regression of hepatocellular carcinoma is reported and compared with the reports published in the English literature. Spontaneous regression of a histologically proven hepatocellular carcinoma was observed in a 42-year-old male patient with chronic hepatitis B. The patient refused to receive any medical therapy. The tumor subsequently regressed without specific treatment, as demonstrated radiologically by computed tomography 22 months and ultrasonography 24 months after initial diagnosis. We review 27 case reports of apparently spontaneous regression of hepatocellular carcinoma that have been published in the English literature from 1982 to 2002. In this report, we present our unusual case and discuss possible causes of spontaneous total necrosis or regression of hepatocellular carcinoma.

Abstract
A solid-phase microextraction (SPME) device was used as a time-weighted average sampler for n-valeraldehyde. The SPME device was first modified to improve the wearer's acceptance as a passive sampler. Then a poly(dimethylsiloxane)-divinylbenzene fiber was used and O-2,3,4,5,6-(pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) was loaded onto the fiber. Vapors of known concentrations around the threshold limit values time-weighted average of n-valeraldehyde and specific relative humidities (RHs) were generated by syringe pumps in a dynamic generation system. n-Valeraldehyde vapors in gas bags were also generated. An exposure chamber was designed to allow measurement of face velocities, temperatures, exposing vapor concentrations, and RHs. Gas chromatography with flame ionization detection was used for sample analysis. The appropriate adsorption time for SPME coating PFBHA was determined to be 2 min and the desorption time for oxime formed after sampling was optimized to be 2 min. The experimental sampling constant was found to be (3.86+/-0.13) x 10(-2) cm3/min and face velocity was not expect to have effect on the sampler.

Abstract
Carcinoma of the uterine cervix is a common malignancy, and many affected women, have been found to exhibit loss of heterozygosity (LOH) in the chromosome 3p region. Recent studies have localized the FHIT (fragile histidine triad) gene in this region and also demonstrated a high frequency of abnormalities of this gene in various cancers. To determine the role of the FHIT gene in cervical and uterine carcinomas, 16 cases of cervical carcinoma and 7 cases of endometrial carcinoma, as well as nearby non-cancerous tissues in these patients, were analyzed by reverse transcription of the FHIT mRNA followed by polymerase chain reaction amplification and sequencing of the products. In this study, 13 of 16 cervical cancers and 4 of 7 endometrial cancers displayed abnormal FHIT transcripts, including a lack of 2 or more exons of the FHIT gene, the insertion of several bases in the deletion junctions, and a 282 bp deletion from cDNA 171 to 452, resulting in a frameshift. Moreover, 5 of 16 matched non-cancerous tissues from the cervical cancer patients and 4 of 7 non-cancerous tissues from endometrial cancer patients also showed the presence of abnormal transcripts lacking 3 or more exons of the FHIT gene. Only 1 of 23 paired samples exhibited LOH. Our results suggest that the abnormal transcript of the FHIT gene is common in both normal and tumor tissues of the uterus and cervix. We also checked for HPV infection in these samples and found no definite relationship between the abnormal transcript and human papillomavirus infection.

Abstract
We report a rare complication of pancarditis in an extreme premature neonate with a peripheral inserted central venous catheter which was positioned in the right atrium. She showed a picture of sepsis, pulmonary embolism, and heart failure. This case emphasizes the need for careful monitoring of the neonate with a central venous catheter to eliminate possible sequel. Echocardiography may help in making an early diagnosis of endocarditis in neonates.
