Purpose: Surgical resection of remnant gastric cancer (RGC) is technically challenging and difficult. Minimally invasive surgery (MIS) has been adopted for various procedures, but reports of MIS for RGC remain limited. Herein, we report the surgical techniques and short-term outcomes of MIS for RGC. Methods: We conducted a retrospective cohort study involving 61 consecutive RGC patients who underwent open or minimally invasive (laparoscopic or robotic) total gastrectomy for potentially curable RGC at our institution (January 1999–August 2025). A propensity scorematched cohort was used for an exploratory evaluation of the safety and efficacy of MIS for RGC, focusing on feasibility rather than superiority over open surgery. Results: Of these 61 patients, 53 underwent open surgery and eight underwent MIS gastrectomy for RGC. The median age was 70 years. The cohort comprised 53 men and eight women. The initial procedure was open surgery in 58 patients and MIS in three patients.Propensity score matching showed significantly reduced intraoperative blood loss in the MIS group compared with the open surgery group (39 mL vs. 576 mL, p < 0.05), and significantly longer operation time in the MIS group (352 minutes vs. 297 minutes, p < 0.05). Postoperative hospital stay was significantly shorter in the MIS group (12 days vs. 17 days, p < 0.05). The incidence of postoperative pancreatic fistula was lower in the MIS group, although not significantly different (0% vs. 16.7%). Conclusion MIS, including robotic gastrectomy, is feasible and safe for RGC, with potential perioperative benefits requiring multicenter validation.

The Japan-Korea Symposium was held on Saturday, May 25th, 2024 as a special program in the 73rd Conference of the Japan Society of Acupuncture and Moxibustion in Miyagi. The topic of the symposium was "The Collaborative Education and Treatment utilizing Acupuncture", which was introduced previously at the Korea-Japan Symposium during the 50th Anniversary Ceremony of the Korean Acupuncture and Moxibustion Medicine Society (KAMMS) in Seoul, Korea in November, 2023. In this article, we summarize the overview of the symposium.

A 24-year-old man was admitted due to fever for two days. He had undergone modified Bentall operation at the age of 18. Transthoracic echocardiography (TTE) showed no findings of infective endocarditis (IE), and he was treated with a course of antibiotics. On the next day, he suffered from aphasia and right hemiplegia, and computed tomography (CT) showed left cerebral infarction due to left middle cerebral artery embolism. The emergent endovascular reperfusion was done, but mild subarachnoid hemorrhage occurred. The following day, TTE showed vegetations and aortic annular abscess, and MSSA was confirmed by blood culture. He was transferred to our institution for surgical treatment for IE. High fever continued, and inflammatory response was recurrent, because the infection was not under control. In addition, multiple systemic thromboembolisms were revealed by contrast-enhanced CT. He recovered to the level of moving his limbs slightly, but he could not speak. We did aortic homograft root replacement and coronary bypass grafting 6 days after the cerebral infarction. His postoperative course was uneventful and he was transferred to rehabilitation hospital on postoperative day 31. He reintegrated into society without neurological complications, and there are no recurrent infections and have been no structural valve deteriorations of the homograft in 5 years.

Background/Aims: Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis and handsewn anastomosis for ulcerative colitis requires pulling down of the ileal pouch into the pelvis, which can be technically challenging. We examined risk factors for the pouch not reaching the anus. Methods: Clinical records of 62 consecutive patients who were scheduled to undergo RPC with handsewn anastomosis at the University of Tokyo Hospital during 1989–2019 were reviewed. Risk factors for non-reaching were analyzed in patients in whom hand sewing was abandoned for stapled anastomosis because of nonreaching. Risk factors for non-reaching in laparoscopic RPC were separately analyzed. Anatomical indicators obtained from presurgical computed tomography (CT) were also evaluated. Results: Thirty-seven of 62 cases underwent laparoscopic procedures. In 6 cases (9.7%), handsewn anastomosis was changed to stapled anastomosis because of non-reaching. Male sex and a laparoscopic approach were independent risk factors of non-reaching. Distance between the terminal of the superior mesenteric artery (SMA) ileal branch and the anus > 11 cm was a risk factor for non-reaching. Conclusions Laparoscopic RPC with handsewn anastomosis may limit extension and induction of the ileal pouch into the anus. Preoperative CT measurement from the terminal SMA to the anus may be useful for predicting non-reaching.

Acute heart failure is associated with high mortality and frequent rehospitalization, resulting in enormous healthcare costs and declining physical function, activities of daily living, and quality of life. Cardiac rehabilitation has been recommended as one of the nonpharmacologic treatments for patients with heart failure. However, much of the evidence for cardiac rehabilitation interventions reported to date has been limited to chronic heart failure. In recent years, the effectiveness of rehabilitation intervention in patients with acute heart failure has been reported, led by the Rehabilitation Therapy in Older Acute Heart Failure Patients (REHAB-HF) trial. This review overviews the recent evidence of rehabilitation in patients with acute heart failure.

The WFAS Annual Conference 2019 was held between November 14th and 17th at Kaya Palazzo Hotel, Antalya, Turkey. The WFAS executive committee was convened on the 14th. In the EC (Executive Committee) meeting, the JSAM proposed inclusion of the Declaration of Helsinki (DoH) in the WFAS Code of Ethics. Other issues discussed in the EC meeting included approval of the special consultative status by the the United Nations ECOSOC (Economic and Social Council) and preparation of the next WFAS symposium in the Netherlands in 2020. Individual presentations and other exhibitions in the symposium are also introduced in the present report. In addition, recent large-scale RCTs of acupuncture conducted in China were reviewed.

The objective of this study is to investigate the effect of the ultrasound-microbubble technique in nuclear factor kappa B (NF-κB) decoy oligodeoxynucleotide (ODN) transfection in the gingival tissue in mice. The 6-FAM-labeled scrambled decoy ODN with microbubbles was applied to the periodontal tissue in 8-week-old male C57BL/6J mice by ultrasound radiation at low (LUM-Sc) and high (HUM-Sc) intensities to optimize the transfection condition of the ultrasound-microbubble method. Histological inspections were performed two hours after transfection to compare the expression with that in the sham-operated group without ultrasound radiation (A-Sc). Then, an NF-κB decoy was transfected into the periodontal tissue using the high-intensity ultrasound-microbubble (HUM-NF) technique to examine the anti-inflammatory effects of the decoy ODN. Western blot analysis was performed to investigate the expression of interleukin(IL)-1β, IL-6 and intercellular adhesion molecule-1 (ICAM-1) in the gingival tissues in the HUM-Sc, the HUM-NF and control groups. The fluorescence microscopy results showed that the fluorescent intensity in the periodontal tissues in the LUM-Sc and HUM-Sc groups was significantly higher than that in the A-Sc and the control groups. The fluorescent intensity in the HUM-Sc group, especially in the gingival connective tissue, was the highest of all groups. Western blot analysis indicated that the protein expression levels of IL-1β, IL-6 and ICAM-1 in the HUM-NF group were significantly lower than those in the HUM-Sc and the control groups. These findings suggest that the high-intensity ultrasound-microbubble technique is an effective tool for decoy transfection into the periodontal tissue.

OBJECTIVE: Electroconvulsive therapy (ECT) is a reasonable option for intractable depression or schizophrenia, but a mechanism of action has not been established. One credible hypothesis is related to neural plasticity. Three genes (Oct4, Sox2, c-Myc) involved in the induction of induced pluripotent stem (iPS) cells are Wnt-target genes, which constitute a key gene group involved in neural plasticity through the TCF family. Klf4 is the other gene among Yamanaka's four transcription factors, and increases in its expression are induced by stimulation of the canonical Wnt pathway. METHODS: We compared the peripheral blood gene expression of the four iPS genes (Oct4, Sox2, c-Myc, and Klf4) before and after modified ECT (specifically ECT with general anesthesia) of patients with intractable depression (n=6) or schizophrenia (n=6). Using Thymatron ten times the total bilateral electrical stimulation was evoked. RESULTS: Both assessments of the symptoms demonstrated significant improvement after mECT stimulation. Expression of all four genes was confirmed to increase after initial stimulation. The gene expression levels after treatment were significantly different from the initial gene expression in all twelve cases at the following treatment stages: at the 3rd mECT for Oct4; at the 6th and 10th mECT for Sox2; and at the 3rd, 6th and 10th mECT for c-Myc. CONCLUSION: These significant differences were not present after correction for multiple testing; however, our data have the potential to explain the molecular mechanisms of mECT from a unique perspective. Further studie should be conducted to clarify the pathophysiological involvement of iPS-inducing genes in ECT.

To evaluate the educational effects of a lung-sound auscultation simulator, “Mr. Lung”, we compared outcomes of fifth-year medical students in 2001 and 2002. From June 2001 through March 2002, we used “Mr. Lung” for small-group teaching for 100 fifth-year medical students. The following year, we opened our laboratory so that the fifth-year students could study with “Mr. Lung” by themselves for 1 month. “Mr. Lung” was then used for objective structured clinical examinations in May 2002. From June 2002 through April 2003, we used “Mr. Lung” again for small-group teaching for 91 fifth-year students. The class consisted of 90 minutes' training for the auscultation of lung sounds. At the beginning of class, auscultation tests were performed in which the students listened through their stethoscopes to 3 examples of abnormal lung sounds on “Mr. Lung” and answered questions about the location and quality of the sounds. The percentages of correct answers in 2001 and 2002, respectively, were 36.9% and 35.4% for differences between bilateral lung sounds, 52.5% and 55.8% for coarse crackles, 34.1% and 58.3%(p<0.05) for fine crackles, 69.2% and 70.8% for wheezes, 62.1% and 90.7%(p<0.01) for rhonchi, and 22.2% and 32.6% for stridor. In conclusion, 1 month's self-study with “Mr. Lung” to prepare for the objective structured clinical examinations improves auscultation skills.
