Abstract	Early diagnosis followed by proper KP is essential for the improvement of long-term prognosis for patients with BA. It is increasingly accepted that KP at ≤ 30 days of age significantly improves native liver survival rate. Published analyses in English and Japanese indicate that screening by SCC and DB/CB is potentially feasible. Screening with SCC has been implemented in Tochigi Prefecture, Japan, since 1994. The concept of SCC was introduced from Japan to Taiwan and resulted in nationwide screening with SCC for the first time in Taiwan in 2004, followed by Japan in 2012. Home-based screening using SCC is easy and cost-effective; however, it may cause some difficulties for families in case of stools with intermediate colors. Laboratory-based screening using DB/CB may detect the suspected cases earlier, resulting in an increase in the number of patients with BA who undergo KP at ≤ 30 days of age; however, the recall rate is 1% and may be beyond an acceptable range. Further studies are needed to assess the feasibility and cost-effectiveness of both home-based (SCC) and laboratory-based (DB/CB) screening for BA.

Abstract	Introduction The usefulness of traction devices (TDs) in endoscopic submucosal dissection (ESD) for rectal neuroendocrine tumors (NETs) has not been reported. The aim of this study was to investigate the impact of using a TD on the vertical margin (VM) distance in the ESD of rectal NETs. Methods In this single-center, retrospective study, we included patients with rectal NETs who were treated with ESD during 2013-2023. They were divided into TD and non-TD groups. One pathologist remeasured the VM distance (primary outcome) and the depth of submucosal invasion (SM depth). Secondary outcomes were margins, resection time, delayed bleeding, and perforation. First, we performed propensity score matching (PSM) to assess the usefulness of TD for VM distance. Then, we used multiple regression analysis to identify factors affecting the VM distance. Results The TD and non-TD groups comprised 24 and 117 lesions, respectively. Patients in the TD group were significantly younger than those in the non-TD group (P = 0.003). In the TD and non-TD groups, the VM distance was 150 μm and 100 μm, respectively (P = 0.70). Only resection time significantly differed between groups, shorter in the TD group (P = 0.005). Twenty-two cases in each group were matched after PSM, yielding no significant differences in VM distance. The use of a TD was not an independent predictor of VM distance (P = 0.65), but age (P < 0.001) and SM depth (P = 0.003) were. Conclusion Using a TD does not seem to affect the VM distance in ESD for rectal NETs.

Abstract	To extract essential information from complex data, computer scientists have been developing machine learning models that learn low-dimensional representation mode. From such advances in machine learning research, not only computer scientists but also social scientists have benefited and advanced their research because human behavior or social phenomena lies in complex data. To document this emerging trend, we survey the recent studies that apply word embedding techniques to human behavior mining, building a taxonomy to illustrate the methods and procedures used in the surveyed papers and highlight the recent emerging trends applying word embedding models to non-textual human behavior data. This survey conducts a simple experiment to warn that common similarity measurements used in the literature could yield different results even if they return consistent results at an aggregate level.

Abstract	With the recent development of technology, data on detailed human temporal behaviors has become available. Many methods have been proposed to mine those human dynamic behavior data and revealed valuable insights for research and businesses. However, most methods analyze only sequence of actions and do not study the inter-temporal information such as the time intervals between actions in a holistic manner. While actions and action time intervals are interdependent, it is challenging to integrate them because they have different natures: time and action. To overcome this challenge, we propose a unified method that analyzes user actions with intertemporal information (time interval). We simultaneously embed the user's action sequence and its time intervals to obtain a low-dimensional representation of the action along with intertemporal information. The paper demonstrates that the proposed method enables us to characterize user actions in terms of temporal context, using three real-world data sets. This paper demonstrates that explicit modeling of action sequences and inter-temporal user behavior information enable successful interpretable analysis.

Abstract	Esophageal stricture caused by complete circumferential endoscopic submucosal dissection (ESD) of extensive esophageal squamous cell carcinoma (ESCC) is a major concern and can result in a low quality of life. Normal mucosa may remain within a complete circumferential lesion of ESCC in some cases. We herein report a case of ESCC in which a complete circumferential lesion was treated with ESD while leaving an island of normal mucosa within it. This case demonstrates that preserving areas of normal mucosa within lesions during complete circumferential ESD is not technically difficult and may be an effective measure for preventing esophageal stricture.

Abstract	The effects of an extended photoperiod (EP) on body composition of Thoroughbreds colts and fillies from December at one year old to April at two years old were investigated. Seventy-three Thoroughbreds reared and trained in Hidaka Training and Research Center, Japan Racing Association, Hokkaido were used. Forty-one horses were under the EP conditions from December 20 to April 15, and the 32 horses were under natural light alone as the control group. Body weight (BW), rump fat thickness (RFT), fat free mass (FFM) and percentage of fat (%F) were used as parameters of body composition. The present study revealed that BW and FFM increased with age in the EP group in colts. In fillies, BW increased with age in both the EP and the control group, however FFM increased with age only in the EP group. From December to April, only colts had a higher rate of increase in both BW and FFM in the EP group than in the control group. However, according to the mean rates of increase in FFM from January to March, the EP group was significantly higher than the control group in both sexes. Furthermore, monthly increase rate of FFM in March was significantly higher in the EP group than in the control group in both sexes. These results suggests that EP treatment to young Thoroughbreds in training at Hokkaido, which is shorter daylength in winter, accelerate the increase of FFM, representing muscle mass.

Abstract	Objective Endoscopic submucosal dissection (ESD) for gastric cancer in the remnant stomach poses some specific technical difficulties due to severe fibrosis and the presence of surgical staples. Therefore, we clarified the feasibility and safety of removing staples. Methods We retrospectively analyzed ESD outcomes of cases of gastric cancer in the remnant stomach. Materials This study reviewed 227 patients who underwent ESD for gastric cancer in the remnant stomach or gastric conduit. Patients were divided into those in whom resection extended to the anastomotic site or suture line (AS group; n=90) and those without such extension (non-AS group; n=137). The AS group was further divided into cases in which staples were removed (staple group; n=22) and those in which they were not (control group; n=68). Results The rates of specimen damage and curative resection and the duration and speed of the procedure were significantly worse in the AS group than the non-AS group. There were no significant differences between the staple group and the control group in the curative or complete resection rates, and no complications occurred in the staple group. In a propensity score-matched analysis, the rate of specimen damage was significantly lower in the staple group than in the control group (p=0.002), and the procedure speed tended to be faster (p=0.077). Conclusion Staple removal may improve the outcomes of ESD in patients with gastric cancer in the remnant stomach or gastric conduit by reducing the risk of specimen damage and increasing the procedure speed without complications.

Abstract	Blue rubber bleb nevus syndrome (BRBNS) is a rare syndrome characterized by venous malformations in the skin and gastrointestinal tract, especially in the small intestine. Patients with BRBNS have increased risks of gastrointestinal hemorrhage and anemia. This is the first report in the English literature on BRBNS with hemangiomas in the small intestine that were treated successfully by endoscopic clipping using double-balloon endoscopy. A 25-year-old Japanese man presented to a local clinic with dyspnea, fatigue, and a hemoglobin level < 5 g/dL. The diagnosis was iron deficiency anemia. Since childhood, he had had a hemangioma in the shoulder joint and hemangiomas in the skin on the left arm. However, neither upper nor lower gastrointestinal endoscopy showed any lesions and he was referred to us for further evaluation and treatment of the anemia. Small bowel capsule endoscopy (SBCE) revealed hemangiomas in the small intestine, one of which was bleeding. Transanal DBE revealed a 10-mm bluish-purple hemangioma with erosion on the surface, which became smaller after application of five clips. Follow-up SBCE on day 50 showed that the hemangioma had completely disappeared. Clipping may be a safe and effective treatment for small bowel hemangioma in BRBNS.
