抄録 Chronic damage accumulation affects not only mortality but also quality of life in patients with systemic lupus erythematosus (SLE). Risk factors for chronic damage were explored in SLE through different onset eras. Two hundred forty-five patients at Okayama University Hospital and Showa University Hospital were divided into three groups based on the onset era: a past-onset group (onset before 1995; n=83), middle-onset group (1996-2009; n=88), and recent-onset group (after 2010; n=74). The mean Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) score as an index of chronic damage was 1.93, 1.24, and 0.53 in the past-, middle-, and recent-onset groups, respectively. In the pastonset group, the total SDI score was significantly associated with glucocorticoid monotherapy by linear regression analysis (β-coefficient [β]=0.63; 95% confidence interval [CI], 0.21-1.05) and C-reactive protein levels (β=0.67; 95% CI, 0.27-1.07). In the middle-onset group, the total SDI score was significantly associated with the SLE Disease Activity Index at registration (β=0.09; 95% CI, 0.03-0.12). Reducing the accumulation of chronic damage in SLE patients might be possible with the concomitant use of immunosuppressants and tight control of disease activity.

抄録 Dickkopf 3 (Dkk3) is a secreted protein belonging to the Dkk family and encoded by the orthologous gene of REIC. Dkk3/REIC is expressed by mouse and human adrenal glands, but the understanding of its roles in this organ is still limited. To determine the functions of Dkk3 in the mouse adrenal gland, we first identified that the mouse Dkk3 protein is N-glycosylated in the adrenal gland as well as in the brain. We performed proteome analysis on adrenal glands from Dkk3-null mice, in which exons 5 and 6 of the Dkk3 gene are deleted. Twodimensional polyacrylamide gel electrophoresis of adrenal proteins from wild-type and Dkk3-null mice revealed 5 protein spots whose intensities were altered between the 2 genotypes. Mass spectrometry analysis of these spots identified binding immunoglobulin protein (BiP), an endoplasmic reticulum (ER) chaperone. To determine whether mouse Dkk3 is involved in the unfolded protein response (UPR), we carried out a reporter assay using ER-stress responsive elements. Forced expression of Dkk3 resulted in the induction of distinct levels of reporter expression, showing the UPR initiated by the ER membrane proteins of activating transcription factor 6 (ATF6) and inositol-requring enzyme 1 (IRE1). Thus, it is possible that Dkk3 is a physiological ER stressor in the mouse adrenal gland.

抄録 An aspiration-type semi-automatic cutting biopsy needle enables tissue cutting during application of negative pressure, which is expected to contribute to a larger amount of specimen. The aim of the present study was to evaluate this novel needle in a clinical setting. Patients who underwent image-guided percutaneous biopsy for lung or renal masses were enrolled. Cutting biopsy was performed with and without aspiration during each procedure. The specimens were weighed using an electronic scale. The weights were compared between specimens obtained with and without aspiration using a paired t-test. The data from 45 lung and 30 renal biopsy procedures were analyzed. In lung biopsy, the mean±standard deviation weights of specimens obtained with and without aspiration were 2.20±1.05 mg and 2.24±1.08 mg, respectively. In renal biopsy, the mean weights were 6.52±2.18 mg and 6.42±1.62 mg, respectively. The weights were not significantly different between specimens obtained with and without aspiration either in lung (p=0.799) or renal (p=0.789) biopsies. The application of negative pressure with the aspiration-type semi-automatic cutting biopsy needle did not contribute to an increase in the amount of the specimen obtained in lung and renal biopsies.

抄録 Due to cultural traditions, most Taiwanese do not have an advance directive or healthcare proxy. We explored how patients with mild dementia in Taiwan may still make self-determined decisions concerning advance directives for their healthcare and end-of-life care choices as the disease progresses. We examined 260 respondents with mild dementia at a Taiwan medical center: 199 patients who agreed (and 61 patients who disagreed) with the concept of advance directives completed a structured questionnaire. Multiple logistic regression models to determine the between-group differences revealed that the following were positively associated with approval of end-of-life directives: maintaining one’s quality of life (adjusted odds ratio [AOR], 2.44; 95% CI: 1.07-5.53), discussion with family members (AOR, 3.50; 95% CI: 1.49-8.26), and friend support networks (AOR, 3.36; 95% CI: 1.34-8.43). Cardiopulmonary resuscitation (AOR, 0.27; 95% CI: 0.09-0.79) was negatively associated with approval. There was also a positive association between the support of the legal validity of end-of-life directives (OR, 1.93; 95% CI: 1.07-3.48), without other confounding factors. In Taiwanese society, we remain mindful of cultural influences that may impact patients, including maintaining one’s quality of life, discussion with family members, and friend/support networks. These influences may help dementia patients complete their advance directives.

抄録 We retrospectively evaluated the cases of 169 hip fracture patients, their previous fractures, and the contralateral hip joint’s morphology. A history of contralateral hip fracture was present in 23 patients (Contra group). The other patients had a unilateral hip fracture: a trochanteric fracture (Troch group, n=73) or a femoral neck fracture (Neck group, n=73). In the Troch and Neck groups, we used anteroposterior and cross-table axialview radiographs of the contralateral hip to evaluate the proximal femur’s anatomy. In the Contra group, the concordance rate between the first and second types of hip fracture was 65.2%, and the second hip fracture’s morphology indicated that the trochanteric fracture had a cam deformity in terms of the femoral head-neck ratio. The average alpha angle and femoral head-neck offset in the Troch group were significantly larger than those in the Neck group. In the Neck group, pistol-grip deformities of Arbeitsgemeinschaft für Osteosynthesefragen types B1 (subcapital), B2 (transcervical), and B3 (displaced) were observed in 42.1%, 75%, and 6% of cases, respectively. There was a smaller alpha angle and a larger femoral head-neck offset in the contralateral hip of femoral neck fractures; thus, the “cam deformity” may protect against femoral neck fractures.

抄録 The purpose of this study was to derive new formulas to provide an optimal surgical procedure and optimal amount of recession-resection (RR) surgery in intermittent exotropia (IXT) with a disparity in angle of deviation depending on the fixation distance. The records of 117 consecutive patients with IXT who underwent RR surgery between March 2008 and December 2011 at Okayama University Hospital were retrospectively examined. Multivariable linear regression analysis was performed using the observed corrective angle of deviation at distance or near fixation as the dependent variable, and amounts of lateral rectus muscle (LR) recession (mm) and medial rectus muscle (MR) resection, and age at surgery (years) as independent variables. Two simultaneous formulas were derived: corrective angle of deviation at distance fixation (°)=1.8×recession (mm)+1.6× resection (mm)+0.15×age (years)–6.6, and corrective angle at near fixation (°)=1.5×recession (mm)+1.7× resection (mm)+0.18×age (years)–3.8. Comparisons of coefficient values of the formulas between distance and near fixation revealed that LR recession was more affected by the corrective angle in distance than near fixation. MR resection was more affected at near than distance fixation. We found that our new formulas estimated the appropriate amount of unilateral RR surgery.

抄録 The physiological role of the reduced expression of immortalized cells (REIC)/Dickkopf-3 (Dkk-3) protein in patients with hepatocellular carcinoma (HCC) remains unclear. In this study, we evaluated the effect of the REIC/Dkk-3 protein on HCC cell proliferation and assessed the relationship between the serum REIC/Dkk-3 protein level and the prognosis in patients with HCC. We evaluated the REIC/Dkk-3 protein-induced anticancer effects on Huh7 and Hep3B cells (HCC cell lines) in the presence of peripheral blood mononuclear cells (PBMCs), and found that combination treatment with REIC/Dkk-3 protein and PBMCs reduced the proliferation of HCC cells (Hep3B: 82.0%±16.3%; Huh7: 72.6%±9.1%). We also studied 194 HCC patients who underwent primary liver resection or primary radiofrequency ablation from 2008 to 2017. Serum REIC/Dkk-3 protein levels were measured by an enzyme-linked immunosorbent assay and compared to the prognostic data. The 3-year disease-free survival of the REIC/Dkk-3 high group was significantly higher than that in the REIC/Dkk-3 low group. In conclusion, this is the first study investigating the relationship between HCC patient survival and serum REIC/Dkk-3 protein levels in a large population. Based on the results, the serum REIC/Dkk-3 protein level should be considered a new prognostic marker for patients with HCC.

抄録 Antithrombotic therapy is a major risk factor for delayed bleeding after endoscopic submucosal dissection (ESD) for gastric neoplasia. A potassium-competitive acid blocker, vonoprazan, is expected to prevent delayed bleeding better than conventional proton pomp inhibitors (PPIs), but the evidence is controversial. We sought to clarify the efficacy of vonoprazan for prevention of delayed bleeding after gastric ESD in patients under antithrombotic therapy. We prospectively registered 50 patients who underwent gastric ESD while receiving antithrombotic therapy and vonoprazan in our institution between October 2017 and September 2018. The incidence of delayed bleeding was compared with that in a historical control group of 116 patients treated with conventional PPI. We also evaluated risk factors associated with delayed bleeding. Delayed bleeding was observed in 8 of 50 patients (16.0%), which was not dissimilar from the incidence in the historical control group (12.1%) (p=0.49). In the univariate analysis, age (> 70 years) (p=0.034), multiple antithrombotic drug use (p<0.01), procedure time (> 200 min) (p=0.038) and tumor size (> 40 mm) (p<0.01) were associated with delayed bleeding after gastric ESD, but vonoprazan was not (p=0.49). Vonoprazan may not be more effective than conventional PPIs in preventing delayed bleeding after gastric ESD in patients receiving antithrombotic therapy.

抄録 A 62-year-old Japanese male presented with graft infection by Staphylococcus schleiferi 50 days after debranching of the left subclavian artery and frozen elephant trunk repair for the entry closure of a Stanford type B aortic dissection. The graft was removed, and the patient was successfully treated using in situ reconstruction of the arch with omental flap coverage, removal of the debranching graft, autologous iliac artery grafting, and longterm antibiotics. Domino reconstruction of the infected debranching graft using autologous external iliac artery and a Dacron graft can thus be a good option in similar cases.

抄録 A 65-year-old Japanese woman developed vesicular eruptions on her right ear due to varicella zoster virus (VZV) reactivation, followed by cranial polyneuritis and meningitis affecting her right cranial nerves V, VII, VIII, IX, and X. After acyclovir administration, her facial paralysis worsened. Intravenous methylprednisolone and vitamin C were administered on Day 4 post-admission. Her symptoms steadily improved, and by Day 45 she had fully recovered. Cranial polyneuritis is a rare complication of VZV reactivation, and there is no established method of treatment. This is the first report of full recovery from cranial polyneuritis using intravenous vitamin C as ancillary treatment.

抄録 Muscle biopsy can be used to confirm the diagnosis of neuromuscular diseases. However, it is unclear whether antibiotic prophylaxis prior to muscle biopsy is needed to prevent surgical site infection (SSI). We are conducting a phase 2, single-center, open-labeled, prospective randomized trial to clarify the need for antibiotic prophylaxis in patients at low risk for SSI undergoing muscle biopsy. Patients will be randomized to an antibiotic prophylaxis group or a control group, and the incidence of SSI will be compared between the groups. Our findings will clarify the need for antibiotic prophylaxis in this patient population.

抄録 Determining factors that predict a favorable disease course without anti-tumor necrosis factor (TNF) agents would help establish a more cost-effective strategy for Crohn’s disease (CD). A retrospective chart review was performed for CD patients with disease durations > 10 years who had not received anti-TNF agents as first-line therapy. Patients were divided into 2 groups: those who received neither anti-TNF agents nor bowel resection (G1), and those who had received an anti-TNF agent and/or bowel resection (G2). The patient backgrounds, therapies and clinical courses were compared between the groups. A total of 62 CD patients met the inclusion criteria (males: 71%; median duration of follow-up: 19 years). Six patients were included in G1; they were significantly less likely to have upper gastrointestinal lesions than G2 (p=0.007). A multivariate analysis revealed that the significant factors for avoidance of bowel resection without anti-TNF treatment were non-stricturing and non-penetrating behaviors, and absence of upper gastrointestinal lesions at the diagnosis (hazard ratios 0.41 and 0.52; p=0.004 and 0.04, respectively). In consideration of the long treatment course of CD, patients with non-stricturing and non-penetrating behaviors and no upper gastrointestinal lesions should not be treated with anti-TNF agents as first-line therapy.

抄録 Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is a promising method for controlling tumors, although it does not entirely eliminate recurrence. Oxidative stress is associated with the progression of hepatocarcinogenesis, while also acting as an anticancer response. The objective of the present study was to investigate the factors influencing post-RFA outcomes. We recruited 235 newly diagnosed HCC patients who received RFA for single tumors. The patients with recurrence were sub-grouped into early and segmental recurrence groups. The characteristics of the sub-grouped patients were evaluated, including by measuring oxidative stress marker reactive oxygen metabolites and antioxidant marker OXY-adsorbent tests. The factors associated with poor survival were a high Child-Pugh score and early recurrence within 2 years in the same segment. The patients who experienced recurrence within 2 years in the same segment showed a larger tumor diameter than did others. According to a multivariate analysis, the OXY values were also significantly low in these patients. In conclusion, maintaining the antioxidant reservoir function with a high OXY value might be necessary to prevent early recurrence within the RFA-treated segment.

抄録 The importance of centralizing treatment services for severely ill children has been well established, but such entralization remains difficult in Japan. We aimed to compare the trauma and illness severity and mortality of children admitted to two common types of ICUs for children. According to the type of management and disposition of the medical provider, we classified ICUs as pediatric ICUs [PICUs] or general ICUs, and analyzed differences in endogenous and exogenous illness settings between them. Overall, 1,333 pediatric patients were included, with 1,143 patients admitted to PICUs and 190 patients to general ICUs. The Pediatric Cerebral Performance Category score (PCPC) at discharge was significantly lower in the PICU group (adjusted OR: 0.45; 95%CI: 0.23-0.88). Death and unfavorable neurological outcomes occurred less often in the PICU group (adjusted OR: 0.29; 95%CI: 0.14-0.60). However, when limited to exogenous illness, PCPC scores (adjusted OR: 0.38; 95%CI: 0.07-1.99) or death/unfavorable outcomes (adjusted OR: 0.72; 95%CI: 0.08-6.34) did not differ between the groups. PCPC deterioration and overall sequelae/death rates were lower in PICUs for children with endogenous illnesses, although the outcomes of exogenous illness were similar between the 2 unit types. Further studies on the necessity of centralization are warranted.

抄録 In this retrospective single-center cohort study, we investigated the impact of preoperative use of an alpha-1 adrenergic receptor (AR) blocker on the outcome of single-session extracorporeal shock wave lithotripsy (SWL) in 193 male patients who underwent SWL for a single ureteral calculus between 2006 and 2016. We reviewed their medical records to obtain the data on the preoperative use of alpha-1 AR blockers. The primary outcome was treatment success after single-session SWL. We performed a multivariable logistic regression analysis adjusting for clinically important confounders to examine the association between preoperative use of alpha-1 AR blockers and the treatment success of SWL. Among the 193 patients, 15 (7.8%) were taking an alpha-1 AR blocker preoperatively. A multivariable analysis showed that preoperative use of an alpha-1 AR blocker was a significant negative predictor for treatment success of SWL (adjusted odds ratio 0.17; 95% confidence intervals, 0.04-0.74). Our findings suggest that the preoperative use of an alpha-1 AR blocker was a negative predictor of treatment success of SWL in male patients with a single ureteral calculus. Clinicians should pay more attention to the preoperative drug use in determining an appropriate stone therapy modality.

抄録 Ketamine has been clinically proven to ameliorate depression, including treatment-resistant depression. The detailed mechanism of action of ketamine in treatment-resistant depression remains unclear. We examined the effects of ketamine on the immobility times of adrenocorticotropic hormone (ACTH)-treated rats during the forced swim test, and we explored the mechanism by which ketamine acts in this model. We investigated the neuroanatomical site of action by microinjecting ketamine into the medial prefrontal cortex of rats. A significant reduction of the rats’ immobility during the forced swim test was observed after the intraperitoneal injection of ketamine in both saline- and ACTH-treated rats. The microinjection of ketamine into the medial prefrontal cortex also decreased immobility during the forced swim test in both saline- and ACTH-treated rats. The immobility-decreasing effect of intraperitoneally injected ketamine was blocked by administering WAY100635, a 5-HT1A receptor antagonist, into the medial prefrontal cortex. These findings contribute to the evidence that ketamine can be useful against treatment-resistant depressive conditions. The immobility-reducing effects of ketamine might be mediated by 5-HT1A receptor activity in the medial prefrontal cortex.

抄録 We examined the effect of D-Tagatose on the growth of oral bacteria including Streptococcus mutans (S. mutans). Saliva collected from 10 healthy volunteers was plated on BHI medium (to culture total oral bacteria) and MBS medium (to culture S. mutans, specifically). Agar plates of BHI or MBS containing xylitol or D-Tagatose were cultured under aerobic or anaerobic conditions. We then counted the number of colonies. In BHI plates containing D-Tagatose, a complete and significant reduction of bacteria occurred under both aerobic and anaerobic conditions. In MSB medium, significant reduction of S. mutans was also observed. We then performed a doubleblind parallel randomized trial with 19 healthy volunteers. They chewed gum containing xylitol, D-Tagatose, or both for 4 weeks, and their saliva was collected weekly and plated on BHI and MSB media. These plates were cultured under anaerobic conditions. Total bacteria and S. mutans were not effectively reduced in either the D-Tagatose or xylitol gum group. However, S. mutans was significantly reduced in volunteers chewing gum containing both D-Tagatose and xylitol. Thus, D-Tagatose inhibited the growth of S. mutans and many types of oral bacteria, indicating that D-Tagatose intake may help prevent dental caries, periodontitis, and many oral diseases.

抄録 Little is known about the role of a strong ions in humans with respiratory abnormalities. In this study, we investigated the associations between partial carbon dioxide pressure (pCO2) and each of sodium ion (Na+) concentrations, chloride ion (Cl−) concentrations and their difference (SIDNa-Cl). Blood gas data were obtained from patients in a teaching hospital intensive care unit between August 2013 and January 2017. The association between pCO2 and SIDNa-Cl was defined as the primary outcome. The associations between pCO2 and [Cl−], [Na+] and other strong ions were secondary outcomes. pCO2 was stratified into 10 mmHg-wide bands and treated as a categorical variable for comparison. As a result, we reviewed 115,936 blood gas data points from 3,840 different ICU stays. There were significant differences in SIDNa-Cl, [Cl−], and [Na+] among all categorized pCO2 bands. The respective pCO2 SIDNa-Cl, [Cl−], and [Na+] correlation coefficients were 0.48, −0.31, and 0.08. SIDNa-Cl increased and [Cl−] decreased with pCO2, with little relationship between pCO2 and [Na+] across subsets. In conclusion, we found relatively strong correlations between pCO2 and SIDNa-Cl in the multiple blood gas datasets examined. Correlations between pCO2 and chloride concentrations, but not sodium concentrations, were further found to be moderate in these ICU data.

抄録 An increasing accumulation of microplastics and further degraded nanoplastics in our environment is suspected to have harmful effects on humans and animals. To clarify this problem, we tested the cytotoxicity of two types of plastic wrap on human cultured liver cells and mouse primary cultured liver cells. Alcohol extracts from plastic wrap, i.e., polyvinylidene chloride (PVDC), showed cytotoxic effects on the cells. Alcohol extracts of polyethylene (PE) wrap were not toxic. The commercially available PVDC wrap consists of vinylidene chloride, epoxidized soybean oil, epoxidized linseed oil as a stiffener and stabilizer; we sought to identify which component(s) are toxic. The epoxidized soybean oil and epoxidized linseed oil exerted strong cytotoxicity, but the plastic raw material itself, vinylidene chloride, did not. Our findings indicate that plastic wraps should be used with caution in order to prevent health risks.

抄録 Since the discovery of the NAB2-STAT6 gene fusion in 2013, solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) have been considered the same disease. STAT6 nuclear stain is approved as a highly sensitive and specific marker to diagnose SFT/HPC from other tumors with similar histology. As the next step, detection of fusion variants that may predict clinical malignancy of SFT/HPC has been attempted. However, no fusion variants with a clear relation to malignancy have been identified. In this study, the clinical and histological backgrounds of 23 Japanese patients diagnosed with SFT/HPC from 2000 to 2019 at Kochi University Hospital were examined to identify factors potentially related to recurrence. A significant relationship to recurrence was detected for mitosis ≥ 1/10 HPF (400×), necrosis, and Ki-67>5%. These findings indicate that a deliberate investigation of histological features such as mitosis and necrosis is crucial for the clinical observation of SFT/ HPC patients. In addition, Ki-67 was revealed to be a useful parameter to predict recurrence in SFT/HPC patients.
