Background/Aims:
Recent studies indicate that probiotics, which have attracted attention as a treatment for irritable bowel syndrome, affect intestinal homeostasis. In this study, we investigated whether Zygosaccharomyces sapae (strain I-6), a probiotic yeast isolated from miso (a traditional Japanese fermented food), could improve irritable bowel syndrome symptoms.
Methods:
Male Wistar rats were exposed to water avoidance stress (WAS). The number of defecations during WAS and the visceral hypersensitivity before and after WAS were evaluated using colorectal distension. Tight junction changes were assessed by Western blotting. Some rats were fed with strain I-6 or β-glucan from strain I-6. Changes in the intestinal microbiota were analyzed.The effect of fecal microbiota transplantation after WAS was evaluated similarly. Caco-2 cells were stimulated with interleukin-1β and tight junction changes were investigated after coculture with strain I-6.
Results:
The increased number of stool pellets and visceral hypersensitivity induced by WAS were suppressed by administering strain I-6. The decrease in tight junction protein occludin by WAS was reversed by the administration of strain I-6. β-Glucan from strain I-6 also suppressed those changes induced by WAS. In the rat intestinal microbiota, treatment with strain I-6 altered the β-diversity and induced changes in bacterial occupancy. Upon fecal microbiota transplantation, some symptoms caused by WAS were ameliorated.
Conclusions
These results suggest that traditional fermented foods such as miso in Japan are valuable sources of probiotic yeast candidates, which may be useful for preventing and treating stress-induced visceral hypersensitivity.

Background/Aims:
The Heart Failure Association (HFA)-PEFF score is recognized as a simple method to diagnose heart failure (HF) with preserved ejection fraction (HFpEF). This study aimed to evaluate the relationship between HFA-PEFF scores and cardiovascular outcomes in HFpEF patients.
Methods:
A total of 502 consecutive HFpEF patients were prospectively observed for up to 1,500 days. Cardiovascular outcomes were compared between two groups of patients, defined by their HFA-PEFF scores: those who scored 2–4 (the intermediate-score group) and those who scored 5–6 group (the high-score group). Overall, 236 cardiovascular events were observed during the follow-up period (median, 1,159 days).
Results:
Kaplan-Meier analysis showed that there were significant differences in composite cardiovascular events and HF-related events between the intermediate-score group and the high-score group (p = 0.003 and p < 0.001, respectively). Multivariate Cox proportional hazards analysis showed that the HFA-PEFF scores significantly predicted future HF-related events (hazard ratio, 1.66; 95% confidence interval [CI], 1.11 to 2.50; p = 0.014); receiver operating characteristic analysis confirmed this relationship (area under the curve, 0.633; 95% CI, 0.574 to 0.692; p < 0.001). The cutoff HFA-PEFF score for the identification of HF-related events was 4.5. Decision curve analysis revealed that combining the HFA-PEFF score with conventional prognostic factors improved the prediction of HF-related events.
Conclusions
HFA-PEFF scores may be useful for predicting HF-related events in HFpEF patients.

Asian Spine Journal 2020;14(6):801-807
Methods:
The subjects were 23 children with LLD ≥20 mm (range, 27–65 mm) treated at Nagoya University Hospital between 2007 and 2017. Whole spine posteroanterior standing radiographs and whole lower limb radiographs in a supine position were recorded. Data were collected for demographics, LLD, Cobb angle, pelvic obliquity, and Nash/Moe index. Scoliosis was defined as a Cobb angle ≥10°. Leg length was measured from the top of the femoral head to the middle of the tibial plafond, and LLD was defined as the difference between the left and right leg lengths.
Results:
The patients (nine males and 14 females) had a mean age of 14.0 years (range, 5–18 years). The average LLD was 44.3±17.2 mm, with LLDs of 20 to 39 mm, 40 to 59 mm, and ≥60 mm in 13, five, and five subjects, respectively. The average Cobb angle was 13.0°±7.0°, and 15 subjects (65%) had scoliosis. Convexity of the scoliosis was to the short leg side in all cases. The Cobb angle was significantly related to the severity of the LLD (R=0.736, p<0.01), pelvic obliquity (R=0.966, p<0.01), and Nash/Moe index (p<0.05).
Conclusions
LLD is a common pediatric condition that can cause scoliosis of the spine. Severe scoliosis may develop if the LLD is ≥30 mm. Long-term studies are needed to examine the effect of LLD resolution on the elimination of scoliosis.

Abstract: We report a case of acquired hemophilia A diagnosed after hospitalization in a palliative care unit. Case: The patient was an 86-year-old man diagnosed with gastric carcinoma one-year prior, who declined treatment but whose progress was being monitored. He was admitted to our hospital due to multiple, systemic, and subcutaneous bleeding and exacerbation of anemia. Blood testing revealed prolonged activated partial thromboplastin time (APTT), but the cause was unknown. Subcutaneous bleeding persisted after hospitalization, accompanied by pain. After admission to a palliative care unit, blood testing revealed only prolonged APTT; hence, a coagulation study was performed, resulting in a diagnosis of acquired hemophilia A. Immunosuppressive therapy was considered but was not performed as the patient’s progress was complicated by aspiration pneumonia for which antibiotics were ineffective, and the patient’s prognosis was determined to be short. The patient died on the 20th day after admission to the palliative care unit. Conclusion: Acquired hemophilia A is a rare hemorrhagic condition, but it is important to suspect it in cases involving prolonged APTT and spontaneous bleeding with no medical history or family history.

BACKGROUND: Waldenström Macroglobulinemia (WM) is a rare subtype of indolent B-cell lymphoma, and prospective randomized studies on WM are scarce. The R-CHOP therapy [rituximab (R), cyclophosphamide, hydroxy-doxorubicin, vincristine, and prednisone] is a popular and recommended regimen for primary therapy, prescribed by several treatment guidelines for WM. However, treatment with R-CHOP is accompanied by severe myelosuppression and high rates of peripheral neuropathy. Therefore, we retrospectively evaluated the efficacy and toxicity of half-dose CHOP combined with R as a primary therapy for WM. METHODS: Patients with untreated symptomatic WM, treated at the Disaster Medical Center between April 2011 and September 2016, were retrospectively analyzed after administration of 6 cycles of half-dose R-CHOP for every 3 weeks. The response, median time to response, best response, progression-free survival, overall survival, and toxicities were evaluated. RESULTS: Of the 20 WM patients analyzed, 16 (80%) received half-dose R-CHOP without vincristine, and 13 (65%) responded to the treatment. With a median follow-up duration of 26.3 months, the 2-year progression-free survival and 2-year overall survival rates were 70 and 93.3%, respectively. The median time to response and best response were 6 and 9.9 weeks, respectively. Grade 3/4 leukocytopenia, neutropenia, febrile neutropenia, and Grade 1 peripheral neuropathy developed in 32, 37, 0, and 21% of patients, respectively. CONCLUSION: The half-dose R-CHOP is an effective and well-tolerated primary therapy for WM. To the best of our knowledge, this is the first study reporting the use of a reduced-dose R-CHOP regimen for the primary treatment of WM.

Several prospective studies on laparoscopy-assisted distal gastrectomy for early gastric cancer have been initiated, but no prospective study evaluating laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy has been completed to date. A non-randomized confirmatory trial was commenced in April 2015 to evaluate the safety of laparoscopy-assisted total gastrectomy and laparoscopy-assisted proximal gastrectomy for clinical stage I gastric cancer. A total of 245 patients will be accrued from 42 Japanese institutions over 3 years. The primary endpoint is the proportion of patients with anastomotic leakage. The secondary endpoints are overall survival, relapse-free survival, proportion of patients with completed laparoscopy-assisted total gastrectomy or laparoscopy-assisted proximal gastrectomy, proportion of patients with conversion to open surgery, adverse events, and short-term clinical outcomes. The UMIN Clinical Trials Registry number is UMIN000017155.
