Abstract
Objective We aimed to investigate the relationship between tortuosity of the extracranial internal carotid artery (ICA) or vertebral artery (VA) and vascular risk factors among residents of Asahikawa, northeast Japan. Methods We retrospectively surveyed participants of "brain dock" medical brain checkups, which involved magnetic resonance imaging and angiography. We measured the tortuosity of the ICA and VA, and evaluated vascular risk factors based on medical interviews, questionnaires, and medical records. Results A total of 218 participants were enrolled in the study. ICA tortuosity (right and left) was significantly correlated with age [odds ratio (OR): 2.452, 95% confidence interval (CI): 1.695-3.548, p<0.001]. A more pronounced correlation was observed in females than in males (OR: 1.678, 95% CI: 1.004-2.807, p=0.048). VA tortuosity (right and left) was significantly correlated with age (OR: 1.786, 95% CI: 1.250-2.550, p=0.001) and smoking history (OR: 2.140, 95% CI: 1.235-3.707, p=0.007), and was more pronounced in females than in males (OR: 1.864, 95% CI: 1.107-3.137, p=0.019). Conclusion ICA tortuosity was correlated with age, while VA tortuosity was correlated with age and smoking history. ICA and VA tortuosity were more pronounced in females than in males.

Abstract
INTRODUCTION Transvaginal mesh surgery (TVM) is an effective treatment measure for pelvic organ prolapse (POP). However, the ORIHIME mesh (Kono Seisakusho, Japan, Tokyo), which has the disadvantage of poor adherence to tissues, is currently the only product available for this procedure. Our research team has previously developed a modified ORIHIME mesh with wider arms with the aim of minimizing the risk of POP recurrence. Additionally, the length of the mesh behind the anterior vaginal wall has been adjusted to prevent urinary incontinence. The current study aims to examine the efficacy of this modified mesh in minimizing postoperative complications in patients undergoing uphold-type TVM. METHODS The data of 84 patients who underwent TVM using ORIHIME at our hospital since July 2019 were retrospectively analyzed. The patients were divided into three groups as follows: (a) normal arms (NA; arm width < 6 cm; n = 29 cases); (b) wide arms without length adjustment (WA and LA (-); arm width > 6 cm; n = 27 cases); and (c) wide arms with length adjustment (WA and LA (+); n = 28 cases). Data were collected using various questionnaires, and the residual urine volume was measured before and after surgery. Additionally, the 60-minute pad test was performed where possible, and the recurrence and complication rates were recorded. RESULTS The incidence of mesh exposure and urinary incontinence in daily life tended to be lower in the WA and LA (+) groups, although this difference was not statistically significant. The one-year postoperative POP recurrence rate, residual urine volume, International Prostate Symptom Score (IPSS), Overactive Bladder Symptom Score (OABSS), and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score were significantly lower in the WA and LA (+) groups compared to the other groups. CONCLUSION Uphold-type TVM using the modified ORIHIME mesh with wider arms and adjusted length was associated with better postoperative treatment outcomes compared to TVM using the traditional ORIHIME mesh.

Abstract
BACKGROUND For patients with gastric cancer, a well-balanced treatment that considers both oncological aspects and surgical risk is demanded. This study aimed to explore the optimal extent of lymph node dissection (LND) for patients with gastric cancer according to surgical risk, stratified by the risk calculator system produced by the Japan National Clinical Database (NCD). PATIENTS AND METHODS We retrospectively evaluated 187 patients who underwent radical gastrectomy for gastric cancer. Using the median predicted anastomotic leak rate obtained by the NCD risk calculator as the cutoff value, we classified 97 and 90 patients as having high and low risks, respectively. RESULTS In low-risk patients, although limited LND reduced the postoperative intraabdominal infectious complications (IAIC), multivariate analysis revealed standard LND as an independent prognostic factor that improved Relapse-free survival (RFS). In high-risk patients, the rates of postoperative IAIC and RFS were similar between standard and limited LND. Pancreatic fistula was not observed in the limited dissection group. CONCLUSION Limited LND might be the optimal treatment strategy for patients with gastric cancer with high surgical risk.

Abstract
Introduction Transvaginal mesh surgery (TVM) is an effective treatment option for pelvic organ prolapse (POP). Although ORIHIME®, the only available mesh product, is thin, soft, and easy to handle, it has the disadvantages of sliding off or mildly adhering to the surrounding tissues. The current study compared the efficacy of using wide-arm ORIHIME (Kono Seisakusho, Japan, Tokyo), non-wide arm ORIHIME, Gynemesh PS (Johnson and Johnson, Japan, Tokyo), and Polyform (Boston Scientific Japan, Japan, Tokyo) meshes for TVM. Methods The study included 116 patients who underwent TVM (Prolift with Gynemesh PS (n = 14); Elevate with Polyform (n = 43); Uphold with non-wide-arm ORIHIME (n = 24); Uphold with wide-arm ORIHIME (n = 35)) at our hospital. Pre- and post-surgical changes in symptoms were measured using questionnaires and 60-minute pad weight testing and compared by mesh type and surgical methods used. Results The residual urine volume, 60-minute pad weight testing, international prostate symptom score (IPSS), overactive bladder symptom score (OABSS), and international consultation on incontinence questionnaire-short form score (ICIQ-SF) significantly improved one year postoperatively in the TVM with the wide-arm ORIHIME group. Comparison of pre and one-year postoperative findings by mesh type and surgical methods used showed no significant differences in the 60-minute pad test, IPSS, Quality of Life (QOL), OABSS, and urinary incontinence in daily life scores, and improvement in residual urine volume, ICIQ-SF, and mesh exposure and POP recurrence rates in the TVM with the wide-arm ORIHIME group. Conclusion TVM with wide-arm ORIHIME had better postoperative outcomes compared to TVM with other mesh products.

Abstract
BACKGROUND Thoracic duct cysts are extremely rare mediastinal tumors. We report a case of a thoracic duct cyst extending from the caudal aspect of the left main bronchus to the left renal artery that was safely and completely resected via bilateral thoracoscopic surgery in the prone position. CASE PRESENTATION A 77-year-old male was referred to our hospital for follow-up computed tomography (CT) of prostate cancer, which revealed a mediastinal tumor and fatty low-density along the posterior mediastinum of the para-aortic artery with a slightly high-density component. Magnetic resonance imaging revealed a T2-weighted image with high intensity. The preoperative radiological diagnosis was lipoma or well-differentiated liposarcoma. CT in the prone position suggested that the tumor could be resected from the thoracic cavity to the caudal side, and bilateral thoracoscopic surgery was performed in the prone position. Based on the surgical findings, the tumor was diagnosed as a thoracic duct cyst rather than a lipoma. Dissection around the thoracic duct cyst was performed using a vessel-sealing system to prevent leakage of the chyle, and reliable clipping was performed to resect the cisterna chyli. Histopathological examination revealed smooth muscle structures around the cyst, suggestive of a thoracic duct cyst. The diagnosis of a thoracic duct cyst was made based on a high triglyceride level of 1310 mg/dL on examination of the milky-white cyst fluid. The patient's postoperative course was uneventful, and he was discharged 4 days postoperatively. A CT scan performed 13 months after surgery showed no recurrence. CONCLUSIONS A rare thoracic duct cyst extending from the mediastinum to the cisterna chyli was safely and completely resected using bilateral thoracoscopic surgery, with the patient in the prone position.

Abstract
OBJECTIVE The aim of this study was to clarify the risk of loss of independence (LOI) following gastrectomy in elderly patients with gastric cancer (GC). METHODS In this prospective study, frailty was assessed preoperatively by a frailty index (FI) in 243 patients aged ≥ 65 years who underwent gastrectomy for GC between August 2016 and December 2020. Patients were assigned into two groups (high FI vs. low FI) to investigate frailty and the risk of LOI after gastrectomy for GC. RESULTS Overall and minor (Clavien-Dindo classification [CD] 1, 2) complication rates were significantly higher in the high FI group, but the two groups had similar rates of major (CD ≥ 3) complications. The frequency of pneumonia was significantly higher in the high FI group. In univariate and multivariate analyses for LOI after surgery, high FI, older age (≥ 75 years), and major (CD ≥ 3) complications were independent risk factors. A risk score assigning 1 point for each of these variables was useful in predicting postoperative LOI (LOI: score 0, 7.4%; score 1, 18.2%; score 2, 43.9%; score 3, 100%; area under the curve [AUC] = 0.765.) CONCLUSIONS: LOI after gastrectomy was independently associated with high FI, older age (≥ 75 years), and major (CD ≥ 3) complications. A simple risk score assigning points for these factors was an accurate predictor of postoperative LOI. We propose that frailty screening should be applied for all elderly GC patients before surgery.

Abstract
A 73-year-old man, who had been treated for bipolar disorder since he was 39 years old, was admitted because he had developed difficulty in walking and moving his hands for the past 2 months. He was suspected of having Parkinson's syndrome. On admission, his blood lithium level was at the upper limit of normal (1.34 mEq/l), but his food intake gradually decreased and his communication difficulties worsened. On the sixth day of hospitalization, his blood lithium level was in the toxic range (2.44 mEq/l). His general condition, including motor symptoms, improved after lithium medication was discontinued and infusions (normal saline) were started. On the 24th day of admission, he was transferred to the psychiatry department for a psychotropic medication adjustment. It is important to note that chronic intoxication can occur even at the upper limit of the therapeutic range and that salt reduction at the start of the inpatient diet may be a trigger for intoxication.

Abstract
Gastric cancer (GC) with microsatellite instability (MSI) has been reported to be sensitive to immunotherapy, however some of GC cases with MSI remain resistant to immunotherapy. Cancer cell lines showing MSI might be useful for the analysis of mechanisms of immunotherapy, while only a few GC cell lines with MSI are available so far. In this study, we established a unique GC cell line with MSI, OCUM-13, from a primary GC with abundant tumor-infiltrating lymphocytes. MSI assay indicated that OCUM-13 cells as well as the primary tumor showed a band shift in more than 3 of 5 microsatellite loci, suggesting that OCUM-13 did have high MSI. The subcutaneous inoculation of OCUM-13 cells into mice performed tumor formation. Insulin-like growth factor 1 receptor inhibitor decreased the growth of OCUM-13 cells. The newly established cell line with MSI, OCUM-13, might be useful for the analysis of cancer therapy for GC with MSI.

Abstract
INTRODUCTION No studies have investigated the prognostic value of left atrial stiffness (LASt) estimated using echocardiography in dogs with myxomatous mitral valve disease (MMVD). ANIMALS Seventy-two dogs had MMVD and 46 dogs were healthy dogs. MATERIALS AND METHODS Clinical retrospective cohort study. The survival information of MMVD dogs that underwent echocardiographic examination was obtained. The peak velocities of early diastolic transmitral flow (E) and mitral annular motion as determined by pulsed wave Doppler (E') were determined. The left atrial reservoir strain (εS) was determined by two-dimensional speckle tracking echocardiography of the left atrium. The LASt was estimated by the formula: E/E'/εS. The 95% prediction interval of LASt was computed from the data of the healthy dogs. RESULTS Seventeen dogs having MMVD died of cardiac-related causes with 55 MMVD dogs censored. The MMVD dogs with LASt > its 95% upper prediction limit (LASt > 0.56; n = 26; median survival time, 484 days; 95% confidence interval, 283 days-indeterminable) had shorter survival times (P<0.001) than those with LASt ≤ its 95% upper prediction limit (LASt ≤ 0.56; n = 46; median survival time, >1112 days; 95% confidence interval, indeterminable). Multivariable Cox's proportional hazard analysis demonstrated that the ratio of the left atrial dimension to the aortic annulus dimension and LASt were independent predictors of cardiac-related death among conventional echocardiographic indices, εS and LASt in MMVD dogs. CONCLUSIONS In dogs with MMVD, increased LASt estimated using echocardiography is an independent predictor of cardiac-related death, and LASt can be more useful for prognostication than εS.

Abstract
Since April 2018, robot-assisted rectal resection has been approved as an insurance medical treatment, and robot- assisted rectal resection is rapidly becoming widespread. Even in robot-assisted laparoscopic surgery, mesorectal division is difficult in a narrow pelvic cavity. At the beginning of the operation, Vessel Sealer ExtendTM(price 89,250 yen)was used, but as the procedure became stable, the mesorectal division was started with bipolar forceps and monopolar scissors. The purpose of this study was to investigate the mesorectal division time and postoperative complications associated with changes in the procedure. 36 patients who underwent robot-assisted anterior resection for rectal cancer by the same surgeon from January 2019 to December 2021. We compared mesorectal division time and postoperative complication. Median operation time were 267 minutes, median console time were 132 minutes. There were no complications such as intestinal obstruction or anastomotic leakage. There was no difference in mesorectal division time time between Vessel Sealer groups and Scissors groups(14 min 55 sec vs 16 min 5 sec). The mesorectal division with bipolar forceps and monopolar scissors could be performed without extending the operation time, and could be performed with cost-benefit and safely.

Abstract
A 63-year-old man visited our hospital with a complaint of penile swelling caused by metallic ring entrapment in the penis. He had put the ring around his penis 4 hours prior and was subsequently unable to remove it. We attempted to remove the ring using a ring cutter but that was unsuccessful. We then inserted two 18 G needles into the corpus cavernosum through the glans penis and removed blood by manual compression according to a technique called the "string method." The swelling gradually decreased, and we successfully removed the ring without destroying it. The total duration of strangulation was about 5 hours. The patient was subsequently discharged after ensuring he had no urinary difficulties. No complications were observed during the follow-up period.In almost all penile strangulation cases caused by hard objects, such as metallic rings, reported in Japan, the objects were typically destroyed and penile puncture and blood removal, as was performed in our case, was rare. Although penile puncture and blood removal is not commonly performed in Japan, this technique can be performed quickly and inexpensively in the emergency room and should be considered an initial treatment for penile strangulation caused by hard objects.

Abstract
A 35-year-old women with sigmoid cancer(pT4aN1aM0, pStage Ⅲb)underwent laparoscopic sigmoidectomy. She had 8 courses of CapeOX for adjuvant chemotherapy, but follow up CT scan 1 year after the operation detected intraabdominal nodules in anastomotic site and in left lower quadrant of abdomen. After 10 courses of IRIS plus bevacizumab, the both intraabdominal nodules decreased in size. Robot assisted laparoscopic lower anterior resection and laparoscopic disseminated nodule resection were performed. The patient had no postoperative complications and the postoperative course was good. She remains alive without recurrence at 6 months after the second operation.

Abstract
This study aimed to investigate the short- and long-term outcomes in patients with sarcopenia who underwent surgery for advanced gastric cancer. We included 76 patients with pStage Ⅱ or Ⅲ gastric cancer who underwent gastrectomy between January 2017 and June 2021. Patients with pT3N0 cancer were excluded. Using the Asian Working Group for Sarcopenia( AWGS)2019 criteria, the patients were divided into the sarcopenia group(S group)and the non-sarcopenia group (NS group). The surgical outcomes, effects on postoperative adjuvant chemotherapy, and prognosis of the 2 groups were evaluated and compared. No significant differences were observed in the operative time, blood loss, postoperative hospital stays, or incidence of postoperative complications with a grade higher than Clavien-Dindo Grade Ⅱ. The number of patients who received postoperative adjuvant chemotherapy was 5(26.3%)in the S group and 38(66.7%)in the NS group which was significantly lower in the S group(p=0.003). The 3-year overall survival rate was 45.7% in the S group and 71.0% in the NS group(p=0.302). There was no significant difference but survival rate was lower in the S group. The results suggest that postoperative adjuvant chemotherapy is not always available for patients with advanced gastric cancer, and that may worsen the prognosis.

Abstract
A 67-year-old man was introduced to examine for abnormal findings in physical examination. Upper gastrointestinal endoscopy detected the 3 lesions and diagnosed multiple gastric cancers with biopsy. Laparoscopic total gastrectomy was performed and final pathological diagnosis was pT2N1M0, pStage ⅡA with HER2 positive(3+). Adjuvant chemotherapy was not administrated. CT findings 6 months after procedure showed 2 liver metastases(S6, S7)and laparoscopic partial liver resection was performed. Pathological findings proved the metastasis of previous gastric cancer. Although adjuvant chemotherapy of S-1 was started 2 months after hepatectomy, CT findings showed second recurrences in liver and right adrenal gland. Chemotherapy was changed to S-1 plus cisplatin(SP)plus trastuzumab. AS these recurrence sites and ascites could not be detected by CT after 6 courses, therapeutic effect was judged as clinical CR(cCR)and SP plus trastuzumab was stopped due to side effect. Since then, regular follow-up CT showed preservation of status of cCR without chemotherapy and he has been alive without recurrence for 8 years and 9 months after gastrectomy. We report a case of recurrent gastric cancer of multiple organ metastasis with long-term survival due to multimodal treatment.

Abstract
A heavy ion beam probe (HIBP) has been designed for the QUEST spherical tokamak to measure plasma turbulence and the profiles of electric potential profiles. Using a cesium ion beam with an energy of several 10 keV, the observable region covers most of the upper half of the plasma. Although the probe beam is deflected by the poloidal magnetic field produced by plasma current and poloidal coil currents, it can be detected under plasma current up to 150 kA by modifying the trajectories with two electrostatic sweepers. According to the numerical estimation of the intensity of the detected beam, sufficient signal intensity for measuring plasma turbulence can be obtained over almost the measurable area when the electron density is up to 1 × 1019 m-3, which is larger than the cut-off density of electron cyclotron heating in QUEST. The performance of the designed HIBP is sufficient to explore the mechanisms of heat and particle transport in magnetically confined plasmas, including the influence of plasma wall interactions, which is a goal of the QUEST project.

Abstract
Anaphylactic reactions during the induction of general anaesthesia are rare. Anaesthetists should determine the pathogenesis of anaphylaxis in order to establish appropriate treatment and prevent recurrence. Very little clinical information has been published to date about anaphylaxis induced by the recently launched drug remimazolam. A 78-year-old man, scheduled for elective surgery for colon cancer, became profoundly hypotensive and hypoxic shortly following the induction of general anaesthesia with remimazolam, remifentanil and rocuronium. His physiological derangement was successfully managed with adrenaline, vasopressors and intravenous fluid resuscitation. His serum tryptase level was significantly elevated and an intradermal test with diluted remimazolam revealed a positive reaction, confirming the diagnosis of anaphylaxis. We believe this is the first case report of remimazolam-induced anaphylactic shock diagnosed with a serum tryptase elevation and positive skin test.

Abstract
BACKGROUND The jumping to conclusions (JTC) bias is the tendency to make immediate decisions based on little information. There are few studies that have investigated the relationship between JTC and frontal lobe function. We examined the association between JTC and the Brief Psychiatric Rating Scale (BPRS), Frontal Assessment Battery (FAB), and Global Assessment of Functioning (GAF) scale in individuals with schizophrenia. METHODS In total, 50 individuals diagnosed with schizophrenia and 50 healthy control individuals were administered the beads task. Individuals diagnosed with schizophrenia were assessed using the FAB, BPRS, and GAF. RESULTS There was a significant negative correlation between JTC and the negative symptoms of the BPRS (rs=-.368, p = .008). There was a significant positive correlation between JTC and the Go/No-Go task of the FAB (rs=.319, p = .026), and the GAF (rs=.433, p = .002). CONCLUSION JTC in individuals with schizophrenia may be categorized according to several causes, including negative symptoms and poor response inhibition.

Abstract
BACKGROUND We reported that chemokine C-X-C motif receptor 2 (CXCR2) signaling appears to play an important role in the pathogenic signaling of gastric cancer (GC), and although CXCR2 may have a role in other solid cancers, the significance of CXCR2 in cholangiocarcinoma (CCA) has not been evaluated. Herein, we determined the clinicopathologic significance of CXCL1-CXCR2 signaling in CCA. MATERIALS AND METHODS Two human CCA cell lines, OCUG-1 and HuCCT1, were used. CXCR2 expression was examined by western blotting. We investigated the effects of CXCL1 on the proliferation (by MTT assay) and migration activity (by a wound-healing assay) of each cell line. Our immunohistochemical study of the cases of 178 CCA patients examined the expression levels of CXCR2 and CXCL1, and we analyzed the relationship between these expression levels and the patients' clinicopathologic features. RESULTS CXCR2 was expressed on both CCA cell lines. CXCL1 significantly inhibited both the proliferative activity and migratory activity of both cell lines. CXCL1 and CXCR2 were immunohistochemically expressed in 73% and 18% of the CCA cases, respectively. The CXCL1-positive group was significantly associated with negative lymph node metastasis (p = 0.043). The CXCR2-positive group showed significantly better survival (p = 0.042, Kaplan-Meier). A multivariate logistic regression analysis revealed that CXCR2 expression (p = 0.031) and lymph node metastasis (p = 0.004) were significantly correlated with the CCA patients' overall survival. CONCLUSION CXCR2 signaling might exert a tumor-suppressive effect on CCA cells. CXCR2 might be a useful independent prognostic marker for CCA patients after surgical resection.

Abstract
Objectives Because the progression of idiopathic normal pressure hydrocephalus (iNPH) is partially irreversible, we hypothesized that early intervention would markedly improve its prognosis. To test this hypothesis, we retrospectively investigated the long-term prognosis of patients with early intervention in the prodromal phase of iNPH. Methods We defined the prodromal phase of iNPH as a 3m Timed Up and Go (TUG) of 13.5 s or less and a Mini-Mental State Examination (MMSE) of 24 or more. Of the 83 iNPH patients who underwent shunt surgery at Osaka Medical and Pharmaceutical University Hospital over 3 years from January 2015, 12 prodromal phase cases (73.3 ± 6.2 years, 10 males and 2 females) were included in the study. The iNPH grading scale (INPHGS), MMSE, Frontal Assessment Battery (FAB), intermittent gait disturbance (IGD), social participation status, and development of comorbidities were evaluated over 4 years. Results Preoperative MMSE was 27.2 ± 1.5, FAB was 14.1 ± 1.8, TUG was 10.7 ± 1.4 s, and total iNPHGS was 2.8 ± 1.4. At 1, 2, 3, and 4 years postoperatively, total INPHGS improved to 0.8, 0.9, 1.5, and 1.7, respectively, and remained significantly better than preoperatively except at 4 years postoperatively. The MMSE improved slightly to 27.5 after 1 year and then declined by 0.35 per year. After 4 years, the mean MMSE was 26.1, and only one patient had an MMSE below 23. FAB improved to 15.2 after 1 year and then declined slowly at 0.85/year. Ten patients (83%) maintained a high capacity for social participation postoperatively. The preoperative tendency to fall and IGD in 9 (75%) and 8 (67%) patients, respectively, completely disappeared postoperatively, resulting in improved mobility. Shunt malfunction associated with four weight fluctuations and one catheter rupture caused temporary worsening of symptoms, which were recovered by valve re-setting and catheter revision, respectively. Conclusion Early intervention in the prodromal phase of iNPH patients maintained good cognitive and mobility function and social participation ability in the long term. The maintenance of long-term cognitive function suggests its preventive effect on dementia. To realize early intervention for iNPH, it is desirable to establish an early diagnosis system for iNPH.

Abstract
The patient was an 81-year-old man who visited a clinic for fever and lower abdominal pain. He was subsequently diagnosed with prostatitis based on computed tomography (CT) findings that showed swelling of the prostate. Despite treatment with antibacterial therapy, his symptoms did not improve significantly. Since the patient also had myelodysplastic syndrome, he was transferred to our hospital and subsequently diagnosed with prostate abscess based on findings on magnetic resonance imaging (MRI). The abscess had spread widely from the dorsal side of the trigone of the bladder to anterior wall of the rectum. Transperineal drainage was performed to preserve the urethral mucosa of the prostatic urethra. Considering the shape of the abscess cavity, one pigtail catheter was placed in the prostate and another was placed transperineally on the dorsal side of the trigone of the bladder. Cystostomy was performed at the same time. Culture of the abscess revealed the presence of Staphylococcus aureus. As there was little exudate from the abscess 9 days after drainage, the pigtail catheter on the dorsal side of the trigone of the bladder was removed following an injection of minocycline into the abscess. CT showed shrinkage of the abscess 4 days later, and the remaining intraprostatic pigtail catheter was removed after an injection of minocycline. The cystostomy pigtail catheter was subsequently removed since the patient was able to urinate smoothly after clamping. MRI confirmed the disappearance of the abscess cavity 2 months later.

Abstract
This study examined whether the systemic inflammatory response present in the early phase of the postoperative state correlates with long-term outcomes and to identify markers in patients with stage II/III gastric cancer. 444 consecutive patients who underwent radical gastrectomy for stage II/III gastric cancer were retrospectively reviewed. We evaluated maximum serum C-reactive protein (CRPmax) and white blood cell count (WBCmax), defined as the maximum serum CRP level and maximum WBC count during the interval from surgery until discharge, as systemic inflammation markers. In univariate analyses, CRPmax, WBCmax and infectious complications were significantly associated with both overall survival (OS) (p < 0.001, p < 0.001 and p = 0.011, respectively) and relapse-free survival (RFS) (p < 0.001, p = 0.001 and p < 0.001, respectively). Multivariate analysis revealed that high-CRPmax (> 9.2 mg/dL) was an independent prognostic factor for OS (hazard ratio (HR) 1.68, 95% confidence interval (CI) 1.19-2.36, p = 0.003) and RFS (HR 1.56, 95% CI 1.12-2.18, p = 0.009), while WBCmax and infectious complications were not. CRPmax, which reflects the magnitude of systemic inflammation induced by surgical stress and postoperative complications in the early phase after surgery, may be a promising prognostic indicator in patients with stage II/III gastric cancer who undergo curative resection.

Abstract
BACKGROUND The impact of robotic gastrectomy (RG) for gastric cancer (GC) on the incidence of postoperative complication is debatable and unclear. METHODS This study enrolled 200 patients with GC who were surgically treated and consisted of 100 RG and 100 laparoscopic gastrectomy (LG) cases using an ultrasonic scalpel. The short-term outcomes were compared between the two groups. These outcomes were compared using a 1:1 propensity score (PS)-matching analysis. RESULTS After PS matching, 76 cases in each group were well matched. Mean surgical time was significantly longer in the RG group than in the LG group (393 vs. 342 min, p < 0.005), whereas mean blood loss during surgery was significantly lower in the RG group than in the LG group (30.1 vs. 50.1 mL, p = 0.023). The median number of surgeons who attend the main part of the surgery was significantly less in the RG group than in the LG group (2.0 vs. 3.0, p = 0.01). The rate of severe intra-abdominal infectious complication was significantly lower in the RG group than in the LG group (0% vs. 9.2%, p = 0.014). The duration from surgery to adjuvant chemotherapy was significantly shorter in the RG group than in the LG group (29.6 ± 11.0 vs. 45.2 ± 27.8 days, p = 0.046). CONCLUSIONS RG using an ultrasonic scalpel may be a viable alternative to LG because of the improvement in the rate of postoperative intra-abdominal infectious complications after curative surgery for GC.

Abstract
BACKGROUND Patients with bipolar disorder (BD) have increased plasma IL-6 levels, which are higher in depressed BD (dBD) than remitted BD (rBD). However, the mechanism that differentiates the cytokine levels between dBD and rBD is not understood. First, we determined whether brain-derived mtDNA can be detected in plasma using neuron-specific mutant Polg1 transgenic (Tg) mice. Second, we investigated whether the plasma circulating cell-free mitochondrial DNA (ccf-mtDNA) differentiate the cytokine levels between dBD and rBD. METHODS Mouse plasma ccf-mtDNA levels were measured using real-time PCR targeting two regions of the mtDNA (CO1 and d-loop) in Tg mice and non-Tg littermates. Human plasma ccf-mtDNA levels were measured using real-time PCR targeting two regions of the mtDNA (ND1 and ND4) and IL-6 levels were evaluated in 10 patients in different states (depressed and remitted) of BD in a longitudinal manner and 10 healthy controls. RESULTS The mouse plasma CO1/D-loop ratio was significantly lower in Tg than non-Tg mice (P = 0.0029). Human plasma ccf-mtDNA copy number, ND4/ND1 ratio, and IL-6 levels were not significantly different between dBD and rBD. Human plasma ccf-mtDNA levels showed a nominal significant correlation with delusional symptoms (P = 0.033, ρ = 0.68). LIMITATIONS A larger sample size is required to generalize the results and to determine whether plasma ccf-mtDNA is associated with systemic inflammation. CONCLUSIONS Tg mice revealed that brain-derived mtDNA could be present in peripheral blood. The present findings did not coincide with our hypothesis that plasma ccf-mtDNA differentiates the cytokine levels between dBD and rBD.

Abstract
OBJECTIVES To clarify a characteristic of dynamic stability during gait in idiopathic normal pressure hydrocephalus (iNPH) and Parkinson's disease (PD), and to explore the association between dynamic stability and disease severity in each disease. MATERIALS AND METHODS The 5-m gait of 36 iNPH (precerebrospinal fluid drainage), 20 PD (medicated state), and 25 healthy controls (HC) were evaluated using three-dimensional motion analysis. Ambulatory dynamic stability was defined as the ability to maintain the extrapolated center of mass within the base of support at heel contact, with the distance between the two referred to as the margin of stability (MOS). RESULTS Anteroposterior direction (AP) MOS was significantly larger in the iNPH and PD groups than in the HC group; no significant difference was found between the iNPH and PD groups. Mediolateral direction (ML) MOS was significantly larger in the iNPH and PD groups than in the HC group and significantly larger in the iNPH group than in the PD group. In the iNPH group, the disease severity was positively correlated with only ML MOS. In the PD group, the disease severity was positively correlated with the AP MOS and ML MOS. CONCLUSIONS Dynamic stability in iNPH increases in AP and ML, and it may be associated with not only iNPH-associated gait disturbance but also with a voluntarily cautious gait strategy. Dynamic stability in PD only increased in AP, and this may be associated with PD symptoms. These findings will help physicians understand the difference in pathological gait including dynamic stability between patients with iNPH and PD.

Abstract
BACKGROUND Although the role of Lipocalin-2 (LCN2) in cancer development has been focused on recent studies, the molecular mechanisms and clinical relevance of LCN2 in gastric cancer (GC) still remain unclear. METHODS Transcriptome analysis of GC samples from public human data was performed according to Lauren's classification and molecular classification. In vitro, Western blotting, RT-PCR, wound healing assay and invasion assay were performed to reveal the function and mechanisms of LCN2 in cell proliferation, migration and invasion using LCN2 knockdown cells. Gene set enrichment analysis (GSEA) of GC samples from public human data was analyzed according to LCN2 expression. The clinical significance of LCN2 expression was investigated in GC patients from public data and our hospital. RESULTS LCN2 was downregulated in diffuse-type GC, as well as in Epithelial-Mesenchymal Transition (EMT) type GC. LCN2 downregulation significantly promoted proliferation, invasion and migration of GC cells. The molecular mechanisms of LCN2 downregulation contribute to Matrix Metalloproteinases-2 (MMP2) stimulation which enhances EMT signaling in GC cells. GSEA revealed that LCN2 downregulation in human samples was involved in EMT signaling. Low LCN2 protein and mRNA levels were significantly associated with poor prognosis in patients with GC. LCN2 mRNA level was an independent prognostic factor for overall survival in GC patients. CONCLUSIONS LCN2 has a critical role in EMT signaling via MMP2 activity during GC progression. Thus, LCN2 might be a promising therapeutic target to revert EMT signaling in GC patients with poor outcomes.

Abstract
Idiopathic hypersomnia (IH) is a rare sleep disorder characterized by excessive daytime sleepiness, great difficulty upon awakening, and prolonged sleep time. In contrast to narcolepsy type 1, which is a well-recognized hypersomnia, the etiology of IH remains poorly understood. No susceptibility loci for IH have been identified, although familial aggregations have been observed among patients with IH. Narcolepsy type 1 is strongly associated with human leukocyte antigen (HLA)-DQB1*06:02; however, no significant associations between IH and HLA alleles have been reported. To identify genetic variants that affect susceptibility to IH, we performed a genome-wide association study (GWAS) and two replication studies involving a total of 414 Japanese patients with IH and 6587 healthy Japanese individuals. A meta-analysis of the three studies found no single-nucleotide polymorphisms (SNPs) that reached the genome-wide significance level. However, we identified several candidate SNPs for IH. For instance, a common genetic variant (rs2250870) within an intron of PDE9A was suggestively associated with IH. rs2250870 was significantly associated with expression levels of PDE9A in not only whole blood but also brain tissues. The leading SNP in the PDE9A region was the same in associations with both IH and PDE9A expression. PDE9A is a potential target in the treatment of several brain diseases, such as depression, schizophrenia, and Alzheimer's disease. It will be necessary to examine whether PDE9A inhibitors that have demonstrated effects on neurophysiologic and cognitive function can contribute to the development of new treatments for IH, as higher expression levels of PDE9A were observed with regard to the risk allele of rs2250870. The present study constitutes the first GWAS of genetic variants associated with IH. A larger replication study will be required to confirm these associations.

Abstract
BACKGROUND/AIM Cancer-associated fibroblasts (CAFs) may promote the malignancy of human scirrhous gastric cancer (SGC) cells. We conducted the present study to identify novel growth factors from CAFs. MATERIALS AND METHODS OCUM-12 and 2 CAF cell lines were used. The proliferation of cancer cells was determined by the number of cancer cells or the MTT assay. The growth factor(s) were purified and characterized by the gel filtration chromatography and protein array. RESULTS The molecular weight of the growth-stimulating factor was estimated to be approximately 66-669 kDa. Protein array of conditioned medium (CM) from CAFs indicated that dipeptidyl peptidase-4 (DPP-4) was one of the growth factors. The addition of CM increased the phosphorylation of C-X-C chemokine receptor 4 (CXCR4). The DPP-4 inhibitor significantly inhibited the growth-stimulating activity of CM. CONCLUSION DPP-4 from CAFs might be one of the growth-stimulating factors for SGC through CXCR4.

Abstract
A 70-year-old man previously underwent laparoscopic total gastrectomy for gastric cancer in 2010 and pathological diagnoses were pT4a, pN3, M0, pStage ⅢC. The postoperative adjuvant chemotherapy was interrupted due to nausea, but the patient had no apparent recurrence within 5 years after gastrectomy. In 2019, a swelling appeared from the left inguinal region to the scrotum, and MRI scan showed subcutaneous edematous changes in the same region. Biopsy showed adenocarcinoma and we diagnosed a recurrence of gastric cancer with skin metastasis. In November 2020, the patient complained of defecation disorder, and CT scan showed a circumferential wall thickening with contrast effect in the rectum. Although colonoscopy revealed rectal stenosis, biopsy specimen showed no malignant findings. We suspected rectal stenosis due to peritoneal dissemination of gastric cancer and performed a colostomy. Intraoperative findings showed that the rectal wall was remarkably thickened with serosal erythema. Adenocarcinoma cells were found from the cytology of ascites. The patient was treated with nab-paclitaxel plus ramucirumab, then treated with nivolumab after failure of first-line therapy.

Abstract
We examined the controlling nutritional status(CONUT)score and the long-term prognosis of colorectal cancer surgery cases. We retrospectively examined the prognosis of colorectal cancer patients who underwent surgery between January 2013 and December 2015. We targeted 449 patients who were able to calculate the CONUT score. A total of 266 patients (59.2%)had normal nutritional status(1 or less)and 183 patients(40.8%)had mildly poor or worse nutritional status (2 or more). The CONUT score was calculated through preoperative blood tests. The relationship between the CONUT score and overall survival was examined in the low and high groups. Overall survival was significantly shorter in the high group but relapse-free survival did not differ significantly between the 2 groups. There was no difference in cancer-specific survival between the 2 groups, but the survival time due to death from other diseases was significantly shorter in the high group. The CONUT score obtained from preoperative blood sampling suggested that the overall survival time was short in the malnourished group, and that it could be used as an index of prognosis due to death from other diseases.

Abstract
Persistent descending mesocolon(PDM)is caused by absence of fusion of the descending colon to the retroperitoneum. A 67-year-old man with bloody stools was diagnosed with rectal cancer on colonoscopy. A computed tomography showed a medial displacement of his descending colon. The preoperative clinical diagnosis was rectal cancer with PDM, and robot assisted low anterior resection was performed. We found that the left-sided colon was shifted to the midline and adhered the cecum and the mesentery of small intestine. Robot assisted surgery enables surgery with the precise adhesiotomy in a stable field. PDM is a relatively rare anatomic abnormality. Character of PDM is adhesion between the left-sided colon and other organs and radially branch from the inferior mesenteric artery. It is important to understand the anatomical characteristics of PDM and to improve on existing surgical procedures to ensure safe robot assisted surgery these patients.

Abstract
We examined 14 cases who underwent robotic rectal resection with neoadjuvant chemotherapy(NAC)or neoadjuvant chemoradiation therapy(NACRT)for local advanced rectal cancer in our hospital from 2018 June to 2020 December. Two patients underwent NACRT, 12 patients underwent NAC. Sex was 10 males and 4 females. The median age was 66. The surgical procedure was ISR 2 cases, LAR 8 cases, APR 4 cases. The median operation time was 397 minutes and the median blood loss was 73 mL. The histological response grade were Grade 3: 1 case, 2: 7 cases, 1b: 3 cases, and 1a: 3 cases. Surgical margin was negative in all cases. Postoperative complications(≥Clavien-Dindo Grade Ⅲ)required reoperation due to intestinal obstruction in 1 case. Urinary dysfunction was nothing in all cases. Although long-term results such as prognosis and function preservation need to be examined, short-term results of robot-assisted rectal resection after NAC or NACRT were generally good.

Abstract
Abstract
Introduction
Postprocedural High platelet reactivity (HPR) seems to associate long term adverse cardiovascular events, mainly intrastent thrombosis. However, the relationship between hyper-acute postprocedural HPR with prasugrel loading and clinical outcomes in acute coronary syndrome (ACS) is still unclear. Moreover, factors contributing HPR in ACS with prasugrel loading are also unknown.
Purpose
This study aimed to assess the impact of hyper-acute postprocedural HPR with prasugrel loading on clinical outcomes in ACS during hospitalization, as well as to define appropriate cut-off values and identify contributing factors of HPR.
Methods
We performed a single-centre, retrospective observational study that enrolled 207 patients who underwent emergent PCI for ACS with prasugrel loading. The P2Y12reaction unit (PRU) value was measured immediately after PCI with the VerifyNow System. The primary endpoint was major adverse cardiac events (MACE, defined as the composite of death, myocardial infarction, stroke, heart failure, ventricular arrhythmia needing defibrillation).
Results
Mean patient age (standard deviation) was 70.5 (±13.0) years, 78.7% were male, and average time from prasugrel intake to PRU calculation was 98.3 (±49.1) min. During a mean hospital stay of 15.9 (±9.3) days, there were 34 in-hospital MACE (16.4%) and 10 deaths (4.8%). Thrombosis events, didn't stand out and mechanical complications, such as cardiac rupture and cardiac tamponade occupies most of cardiovascular death which occurred before 10 days on admission. PRU was significantly higher in MACE group than Non-MACE group (279±65 vs 227±72, p<0.001 respectively). The ROC curve analysis of PRU for discriminating significant in-hospital MACE showed the cut off value of 293 (sensitivity:52.9%, specificity:83.2% [AUC=0.709, p<0.0001]). 47patients (29.4%) were thus categorized as HPR (PRU>293) immediately after emergent PCI. Kaplan-Meyer curve showed MACE events occurred in HPR group than non-HPR group (38.2% vs 10.0%, p<0.001). Multiple cox analysis demonstrated that HPR was independent predictors of MACE in patients with ACS underwent PCI (OR 5.416, 95% CI 2.157–13.598, p<0.0001). Multiple logistic regression model showed female sex, low haemoglobin value, and large mean platelet volume were independent predictors of HPR.
Conclusion
PRU was significantly higher in MACE group, and appropriate cut-off value of HPR in this study was 293. HPR was independent predictor of MACE during hospitalization, however thrombosis event was not significant. Evidence of clinical impact with postprocedural HPR within 120 minutes after prasugrel loading is scarce. This study shows post-procedural HPR, even without sufficient time after prasugrel intake, can be a useful predictive marker of adverse events during hospitalization.

Abstract
Abstract
Background
Patients with diabetes mellitus are at very high risk for obstructive coronary artery disease; however, invasive coronary angiography is not allowed to apply in all patients. Cardio-ankle vascular index (CAVI), a marker of arterial stiffness has been reported to reflect atherosclerotic burden.
Purpose
To assess the diagnostic performance of CAVI vs. coronary calcium score for detecting obstructive coronary artery disease determined by Coronary CT angiography (CCTA) in asymptomatic diabetes patients.
Methods
During May 2015 to December 2019, 816 patients with diabetes mellitus were evaluated. First, intima-media thickness of carotid artery was measured in all subjects. Then, patients with intima-media thickness over 11mm underwent CAVI. Finally, 209 patients who have one or more cardiovascular risk factors other than diabetes mellitus were enrolled (68±11 years, 68% men). Patients were excluded if they had a disorder of the kidney, a prior history of coronary artery revascularization, atrial fibrillation, LV ejection fraction <50%, ABI <0.9 or allergy to contrast. Diagnostic performance of CAVI was evaluated with coronary stenosis >50% by CCTA.
Results
CAVI, Agatston score, and intima-media thickness of carotid artery were 9.2±1.3, 396±621 and 2.0±0.7mm, respectively. CAVI was significantly correlated with age (r=0.530, p<0.001), coronary artery calcification (r=0.182, p=0.008), and intima-media thickness of carotid artery (r=0.195, p=0.005). Among them, 108 patients (48%) had coronary stenosis. CAVI, Agatston score and intima-media thickness of carotid artery in patients with coronary stenosis were higher than that without coronary stenosis, respectively (9.8±1.1 vs 8.5±1.0, p<0.001, 526±676 vs. 255±525, p=0.001, 2.2±0.7 vs. 1.8±0.6, p<0.001). The ROC curve analysis of CAVI for discriminating coronary stenosis showed that the sensitivity 75.0% and specificity 77.2% at the cut off value of 9.23 (AUC=0.812, p<0.001). Contrastingly, diagnostic performance of coronary calcium score and intima-media thickness of carotid artery were less than CAVI (sensitivity: 91.7%, specificity: 56.4%, AUC=0.753, p<0.05 vs. CAVI, sensitivity: 68.5%, specificity: 59.4%, AUC=0.663, p<0.05 vs. CAVI). Multivariate logistic analysis demonstrated that CAVI was significantly associated with coronary stenosis (OR=4.133, p<0.001) after adjustment of conventional risk factors, although coronary calcium score was not correlated with coronary stenosis.
Conclusion
CAVI could be informative to select patients having obstructive coronary artery disease in asymptomatic diabetes patients with thick intima-media thickness.

Abstract
Abstract
Background/Introduction
Previous studies demonstrated that high platelet reactivity (HPR) predicts future cardiovascular death and coronary events in patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS). However, few studies have focused on the impact of HPR on left ventricular remodeling (LVR) and each echocardiographic parameter.
Purpose
The purpose of this study was to investigate the impact of HPR in ACS patients on LVR and changes in echocardiographic volume indexes and LV ejection fraction.
Methods
This is a retrospective cohort study of prospectively collected data in a single center that enrolled patients who underwent emergency PCI for ACS including STEMI and NSTEMI with prasugrel loading. The primary outcome of the study was LVR associated with HPR. Secondary endpoints were changes in indexed LVESV, LVEDV, LVEF, E/e' and LAVI between baseline and follow-up. The P2Y12 reaction unit (PRU) value in response to prasugrel was assessed by the VerifyNow P2Y12 assay. Blood samples were collected once per procedure immediately after PCI. LVR index was calculated as the relative change in LVEDV observed at follow-up compared with baseline. LVR was defined as a relative increase in LVEDV ≥20%, measured at follow-up visit compared with the baseline value before discharge.
Results
A total of 196 ACS patients who underwent emergency PCI between January 2016 and July 2020 were enrolled in the study. The mean age of the study population was 69.9 years, and 76.0% were male. On echocardiography at follow up visit of mean duration of 7.0±4.0 months, LVR was found in 38 patients (19.4%). The optimal cutoff for PRU associated with increased LVR assessed by receiver-operating characteristic curve analysis was 245.5 (AUC: 0.656; 95% CI: 0.564 to 0.749; p=0.003). On the basis of this cutoff, HPR was found in 82 patients (42.1%) and the prevalence of LVR was significantly higher in the HPR group compared to the non-HPR group (30.5% vs. 11.4%; p=0.001). Multiple Cox regression analysis showed that HPR was an independent predictor of LVR (OR 4.22, 95% CI 1.83–9.71, p=0.001). In addition, Δ% EDV and Δ% ESV increased in the HPR group, and decreased in the non-HPR group with significant differences (5.8±32.6% vs. −8.0±26.2% in Δ% EDV; p=0.002, 2.0±37.5% vs. −13.3±33.0% in Δ% ESV; p=0.004, respectively). Δ%EF, Δ%E/e', Δ%LAVI were numerically improved in the non-HPR group compared with the HPR group, but this difference did not reach statistical significance.
Conclusion
In patients with ACS, HPR defined as PRU ≥246 immediately after emergency PCI was an independent predictor of LVR in the chronic phase.

Abstract
Peritoneal metastasis of gastric cancer (GC) results in extremely poor prognoses. The peritoneal cavity is covered by a monolayer of peritoneal mesothelial cells (PMCs). Interactions between GC cells and PMCs might play a pivotal role in peritoneal metastasis. Extracellular vesicles (EVs) correlate with intercellular communication. Although intercellular communication between cancer cells and PMCs might be associated with the peritoneal metastatic process, the role of EVs from PMCs remains unclear. We investigated the effects of EVs from PMCs on GC cells. Three GC cell lines (OCUM-12, NUGC-3, and MKN74) and four mesothelial cell lines were used. The effects of EVs derived from the PMCs on the invasion and migration of GC cells were evaluated by Matrigel invasion assay. Factors contained in the PMC EVs were analyzed; extra-cellular matrix metalloproteinase inducer (EMMPRIN) was detected in the EVs. The effects of an EMMPRIN inhibitor on the invasion-stimulating activity of EVs were examined. The EMMPRIN expressions of 110 GCs were evaluated by immunohistochemistry. PMC EVs significantly promoted the invasion of diffuse-type GC cells, i.e., OCUM-12 and NUGC-3 cells. EMMPRIN in the EVs stimulated the invasion of OCUM-12 and NUGC-3 cells. The invasion-stimulating activity of PMC EVs was inhibited by the EMMPRIN inhibitor. A high EMMPRIN expression in PMCs was significantly associated with worse cancer-specific survival and peritoneal-recurrence-free survival. EMMPRIN in EVs from PMCs might stimulate the malignant progression of diffuse-type GC. EMMPRIN might be a useful prognostic marker of recurrence in GC patients.

Abstract
Background Gastric cancer (GC) patients frequently develop peritoneal metastasis. Recently, it has been reported that peritoneal mesothelial cells (PMCs) activated by GC cells acquire a migratory capacity and promote GC cell invasion. The invasiveness of PMCs reportedly depends on the activity of Tks5, an adaptor protein required for invadopodia formation. However, the relationship between clinicopathologic features and Tks5 expression in PMCs has been poorly documented. In this study, we evaluated the clinicopathologic significance of the Tks5 expression of PMCs in GC patients. Materials and methods A total of 110 GC patients who underwent gastrectomy were enrolled in this study. Tks5 expressions in PMCs from the greater omentum, lesser omentum and retroperitoneum were evaluated by immunohistochemistry. We analyzed the correlation between Tks5 expressions in PMCs and the patients’ clinicopathologic features. Results Tks5 expression was found in 71 (64.5%) of the 110 patients, while 39 (35.5%) were Tks5-negative. Tks5 positivity was significantly (p = 0.038) associated with a greater tumor depth (i.e., T3/4 compared with T1/T2). Peritoneal recurrence was found in 12 of 98 cases within 3 years of surgery. The 3-year peritoneal recurrence-free survival (PRFS) rate in Tks5-positive cases was significantly poorer than that in Tks5-negative cases (80.1% vs 97.4%, p = 0.024). Multivariate analysis revealed that Tks5 positivity and lymph node metastasis were independent factors for PRFS. Conclusion Tks5 is frequently expressed in PMCs in advanced-stage gastric cancer. Tks5 might be a useful predictor for peritoneal recurrence in GC patients.

Abstract
Freezing of gait (FOG) appears to be associated with increased risk of forward falls in patients with Parkinson's disease (PD). This study aimed to experimentally validate forward gait instability in PD patients with FOG (PD + FOG). Eleven PD + FOG patients, 9 PD patients without FOG (PD - FOG), and 13 healthy controls participated. Self-selected paced gait was analyzed by a three-dimensional motion-capture analysis system. We assessed the distance between the center of mass and the base of support (COM-BOS distance) and the margin of stability (MOS), considering the position and velocity of the COM as gait stability parameters, spatiotemporal gait parameters and kinematic parameters. The anteroposterior COM-BOS distance was smaller in PD + FOG patients than in PD-FOG patients and controls. Anteroposterior MOS was larger in PD + FOG and PD - FOG patients than controls (p < 0.05). PD + FOG patients showed smaller anteroposterior MOS than PD - FOG patients, when adjusting for disease severity (p < 0.05). Only in the PD + FOG group, when adjusting for disease severity, step length was positively correlated with the anteroposterior COM-BOS distance (p < 0.05), and cadence was negatively correlated with the anteroposterior MOS (p < 0.05). These results indicated that PD patients with FOG have forward gait instability and suggested that such instability may be associated with reduced step length and increased cadence.

Abstract
OBJECTIVES We evaluated the perceived and actual changes in gait and balance function immediately after cerebrospinal fluid (CSF) shunting in patients with idiopathic normal pressure hydrocephalus (iNPH), including those with mild cases. MATERIALS AND METHODS Ninety-nine iNPH patients were assessed using the timed Up and Go (TUG) and Functional Gait Assessment (FGA) before and 1-week after CSF shunting and their perceived changes were assessed on a Global Rate of Change (GRC) scale. Minimal clinically important differences (MCIDs) were calculated using a receiver operating characteristic (ROC) curve method using GRC scores. RESULTS In all patients (n = 99), the TUG value postoperatively was significantly faster than the preoperative value (difference; 3.1 ± 4.6 s, p < 0.001), and the postoperative FGA score was significantly better than the preoperative score (difference; 3.8 ± 3.3 points, p < 0.001). In the TUG <15 s group (n = 51), the postoperative FGA score was significantly improved (difference; 3.3 ± 2.9 points, p < 0.001), whereas the TUG value was only slightly improved (difference; 0.6 ± 1.6 s, p = 0.008). The ROC curve MCIDs of GRC ≥2 points, which is the recommended level of improvement, were 1.7 s (16.5%) for the TUG and 4 points (20.0%) for the FGA in all patients (n = 99) and the TUG <15 s group (n = 51). CONCLUSIONS FGA can be used to confirm treatment effects, including perceived and actual changes after CSF shunting, in patients with mild iNPH. Our results can help clinicians to determine the clinical significance of improvements in gait and balance function immediately after CSF shunting in individual patients with iNPH.

Abstract
Abstract
Background: Peritoneal dissemination is one of common causes of poor prognosis of patients with gastric cancer (GC). The mechanism of peritoneal metastasis has not been fully elucidated. Recent studies have reported that extracellular vesicles (EVs) play an important role for the intercellular communication in GC microenvironment. The peritoneal dissemination possesses some intercellular communication steps between cancer cells and hostile cells including peritoneal mesothelial cells (PMCs), however, the effect of EVs derived from PMCs on GC cells has not been validated. In the present study, to clarify the intercellular communication we evaluated the effect of EVs from PMCs on the proliferation, migration and invasion of GC cells.
Materials and Methods: Four GC cell lines (OCUM12, NUGC3, MKN45, MKN74) and 4 PMCs cell lines were used. PMCs cell lines were primary cultured from ascites of gastric cancer patients. The EVs derived from PMCs were isolated from conditioned medium of PMCs by ultracentrifugation. The EVs derived from PMCs were confirmed by the transmission electron microscope (TEM) using uranyl acetate and the western blotting using EV markers such as CD9, CD63, and CD81. The EVs derived from PMCs were fluorescently labelled using PKH26 and the uptakes of EVs were viewed under a fluorescence microscope. The effect of EVs from PMCs on the proliferation, migration and invasion of GC cells was evaluated by MTT assay, wound healing assay and Matrigel invasion assay respectively.
Results: The EVs derived from PMCs showed typical morphology of EVs by TEM, and were positive for EV markers such as CD9, CD63, and CD81 in western blotting. The EVs derived from PMCs significantly suppressed the proliferation of GC cells. On the other hand, the EVs derived from PMCs significantly promoted the migration of OCUM12 and NUGC3 cells, but not MKN45 and MKN74 cells. Furthermore, The EVs derived from PMCs significantly promoted the invasion of OCUM12 and NUGC3 cells. PKH26 labelled EVs derived from PMCs were found in cytoplasm of OCUM12 and NUGC3 cells.
Conclusion: The EVs derived from PMCs significantly promoted the migration and invasion of GC cells. The EVs derived from PMCs might be one of factors which associate with the intercellular communication steps in peritoneal dissemination possesses in GC.

Abstract
Abstract
Background: Cancer progression has been recognized as not only the proliferation of tumor cells but also an interaction between cancer cells and the surrounding stroma in the tumor microenvironment. Among the tumor stromal cells, cancer-associated fibroblasts (CAF) have been reported to be closely associated with tumor development in various solid carcinomas. We previously reported that chemokine (C-X-C motif) receptor 2 (CXCR2) signaling might play an important role for the pathogenic construction of CAF in the gastric cancer (GC) microenvironment, suggesting that GC cells might alter their adjacent stroma to form a permissive environment for tumor progression, and also we reported that chemokine (C-X-C motif) ligand 1 (CXCL1) from cells stimulated the recruitment of bone marrow cells into GC microenvironment via CXCR2 signaling, resulting in the malignant progression of GC. Following these findings, we reported that among the CXCR2 ligands, CXCL1 might play an important role in the malignant progression of GC via CXCR2 signaling. And then, some studies suggest that CXCR2-CXCL1 plays an important role in not only GC but also other solid cancer. However, there is no report about the clinicopathological significance of CXCR2-CXCL1 signal in cholangiocarcinoma. Then, we examined the clinicopathological significance of CXCR2-CXCL1 signal in cholangiocarcinoma in this study.
Patients and Method: We retrospectively analyzed the total cases of 168 patients with cholangiocarcinoma. The expressions of CXCR2 and CXCL1 were investigated by immunohistochemistry, and we then analyzed the correlation between the clinicopathological features of 168 patients and the CXCR2 and CXCL1 expression level.
Results: The CXCR2 and CXCL1 positive expression wad as follows: CXCR2 was 18.5% (31/168), CXCL1 was 72.8% (126/173), both CXCR2 and CXCL1 was 17.9% (30/168). Metastasis negative was correlated with CXCL1 expression. Low depth invasion was correlated with CXCR2 expression. The prognoses of the both CXCR2 and CXCL1 positive patients were significantly better than those of CXCR2 and/or CXCL1 negative patients (p<0.023, log rank).
Conclusion:CXCLR2 and CXCL1 expression might be a better prognostic factor of patients with cholangiocarcinoma, and CXCR2-CXCL1 signaling might play an important role for tumor-suppressing effects of cholangiocarcinoma.

Abstract
Scirrhous-type gastric carcinoma (SGC), which is characterized by the rapid proliferation of cancer cells accompanied by extensive fibrosis, shows extremely poor survival. A reason for the poor prognosis of SGC is that the driver gene responsible for SGC has not been identified. To identify the characteristic driver gene of SGC, we examined the genomic landscape of six human SGC cell lines of OCUM-1, OCUM-2M, OCUM-8, OCUM-9, OCUM-12 and OCUM-14, using multiplex gene panel testing by next-generation sequencing. In this study, the non-synonymous mutations of serine threonine kinase 11/liver kinase B1 (STK11/LKB1) gene were detected in OCUM-12, OCUM-2M and OCUM-14 among the six SGC cell lines. Capillary sequencing analysis confirmed the non-sense or missense mutation of STK11/LKB1 in the three cell lines. Western blot analysis showed that LKB1 expression was decreased in OCUM-12 cells and OCUM-14 cells harboring STK11/LKB1 mutation. The mammalian target of rapamycin (mTOR) inhibitor significantly inhibited the proliferation of OCUM-12 and OCUM-14 cells. The correlations between STK11/LKB1 expression and clinicopathologic features of gastric cancer were examined using 708 primary gastric carcinomas by immunochemical study. The low STK11/LKB1 expression group was significantly associated with SGC, high invasion depth and frequent nodal involvement, in compared with the high STK11/LKB1 expression group. Collectively, our study demonstrated that STK11/LKB1 mutation might be responsible for the progression of SGC, and suggested that mTOR signaling by STK11/LKB1 mutation might be one of therapeutic targets for patients with SGC.

Abstract
There have been a few reports on Dipeptidyl peptidase (DPP)-4 inhibitor-induced dropped head syndrome. However, there has been no known report on temporal changes in MRI findings. The patient described here was a 63-year-old man who was prescribed oral sitagliptin (50 mg/day) in February 2019. He experienced a dropped head from mid-January 2020, and in early April that year, he was admitted to our hospital for further evaluation. Weakness of the cervical extensor muscles (MMT 3) was noted, and MRI findings showed that the posterior cervical muscle group was hyperintense on short inversion time inversion recovery (STIR). We suspected sitagliptin to be the cause of his dropped head and discontinued it. On the 10th day of admission, his posture improved to the median position. One month after discontinuation of sitagliptin, MRI findings showed an improvement in the STIR hyperintensity of the posterior cervical muscle. In conclusion, if the initiation of a DPP-4 inhibitor results in dropped head syndrome, discontinuation of the drug should be considered.

Abstract
OBJECTIVE Immediate single instillation of chemotherapy following transurethral resection of bladder tumor (TURBT) is suggested for non-muscle invasive bladder cancer (NMIBC) patients. However, no study has evaluated molecular marker that was involved in intravesical recurrence (IVR) after single instillation of chemotherapy. Therefore, this study aimed to evaluate whether P-glycoprotein, multidrug resistance protein 1 (MRP1), Annexin A2 (ANXA2) or nucleophosmin (NPM) expression predicts IVR after initial TURBT and immediate single intravesical adriamycin instillation. METHODS We retrospectively reviewed consecutive 443 patients who underwent TURBT. Of these, 54 patients who underwent initial TURBT and single instillation of adriamycin for NMIBC were included. The expressions of P-glycoprotein, MRP1, ANXA2 and NPM were evaluated immunohistochemically and were divided into 2 groups (low or high) according to the staining intensity and/or proportion of positive cells. IVR was assessed by Kaplan-Meier method. Cox`s multivaritate analyses were performed to identify independent predictors for IVR. RESULTS Nineteen patients (35.1%) had IVR. High P-glycoprotein expression was significantly correlated with multiplicity, pT stage and high grade. High ANXA2 expression was significantly correlated with high grade. MRP1 and NPM were not correlated with any clinicopathological variables. MRP1 expression and ANXA2 expression were significantly correlated with P-glycoprotein expression. Patients with high P-glycoprotein expression had significantly worse IVR-free survival (IVRFS) than those with low P-glycoprotein expression (P =0.015). The difference in IVRFS rates between patients with high ANXA2 expression and those with low ANXA2 expression was nearly significant (P =0.057). Univariate analyses indicated multiplicity, high grade and high P-glycoprotein expression were significant predictors for IVR. Multivariate analysis indicated high grade was an independent predictor for IVR. CONCLUSIONS High P-glycoprotein expression was associated with IVR. Further study was needed to determine significance of P-glycoprotein expression in IVR after single intravesical adriamycin instillation.

Abstract
It has been previously indicated that preoperative plasma fibrinogen levels can correlate with cancer progression and be used as a useful predictor of lymph node metastasis or its premetastatic status such as lymphovascular invasion (LVI). In the present study, how preoperative plasma fibrinogen levels, considered in conjunction with other clinicopathological factors, can predict the presence of LVI and prognosisin patients with upper urinary tract urothelial carcinoma (UTUC) was examined. Medical records of 145 patients with UTUC who underwent radical nephroureterectomy (RNU) were retrospectively reviewed. The current study evaluated systemic inflammatory response markers including levels of plasma fibrinogen and other clinicopathological factors in orderto determine independent predictors of LVI and prognosis. The Cox proportional hazards model indicated that positive surgical margins and LVI were independent factors for poor cancer-specific survival (CSS) rates and extraurothelial recurrence-free survival (ERFS) rates. In addition, positive cytology, the presence of hydronephrosis and plasma fibrinogen levels were significant preoperative predictors of LVI. Furthermore, patients exhibiting two or more of higher fibrinogen levels (≥400 mg/dl), positive urine cytology and the presence of hydronephrosis were indicated to exhibit worse CSS or ERFS rates compared with patients exhibiting only one of the aforementioned factors or those with none of the three aforementioned factors in the multivariate analysis of the Cox proportional hazards model. In conclusion, hyperfibrinogenemia can be an independent predictor of the presence of LVI, and stratifying preoperative risk using fibrinogen levels, urine cytology and hydronephrosis can serve as the basis for selecting candidates for additional therapy before and/or after RNU in patients with UTUC.

Abstract
Trophoblast cell-surface antigen 2 (TROP2) is a transmembrane glycoprotein expressed in epithelial cells. Increased TROP2 expression has been reported to be associated with malignant progression in most carcinomas; however, TROP2 has a tumor-suppressive function in certain types of cancer. Since the function of TROP2 is controversial, the present study subsequently aimed to clarify the clinicopathologic significance of TROP2 and pTROP2 expression in human gastric cancer (GC). The cases of 704 patients with GC who underwent gastrectomy were retrospectively analyzed. The expression levels of TROP2 and pTROP2 in each tumor were evaluated by immunohistochemistry. The association between the clinicopathologic features of patients with GC and the levels of TROP2 and pTROP2 in their tumors was analyzed. Increased TROP2 and pTROP2 expression was identified in 330 (46.9%) and 306 (43.5%) of the 704 patients with GC, respectively. Increased TROP2 expression was associated with the histological intestinal type, high tumor invasion depth (T3/T4), lymph node metastasis, lymphatic invasion and venous invasion. By contrast, increased pTROP2 expression was associated with intestinal type, low tumor invasion depth (T1/2), no lymph node metastasis and no lymphatic invasion. Increased TROP2 expression was associated with poorer overall survival (OS) (P<0.01; log rank test), whereas increased pTROP2 expression was significantly associated with improved OS (P<0.01; log rank test). In conclusion, increased expression levels of TROP2, but not pTROP2, may be associated with the metastatic ability of GC, resulting in poor prognosis of patients with GC.
