Abstract
INTRODUCTION A remission induction therapy of granulocyte and monocyte adsorptive apheresis (GMA) was given to patients with Crohn's disease (CD). However, establishing an appropriate treatment strategy for GMA in patients with CD remains unclear. METHODS This study evaluated the clinical efficacy and subsequent clinical progression after GMA in patients with CD who underwent GMA in seven independent institutions in Japan from 2010 to 2023. RESULTS Sixteen patients were enrolled. The overall remission and response rates were 25.0% and 68.8%, respectively. All patients responding to GMA received biologics that were continuously used and 36.4% of patients remained on the same biologics 52 weeks after GMA. Notably, all patients who continued the same biologics had previously experienced a loss of response to biologics. CONCLUSION GMA may exhibit effectiveness even in cases with refractory CD. Moreover, it represents a potential novel therapeutic option for refractory CD with loss of response to biologics.

Abstract
BACKGROUND Granulocyte and monocyte adsorptive apheresis (GMA) with Adacolumn has been used as a remission induction therapy for patients with active ulcerative colitis (UC). Herein, we investigated the influence of concomitant medications in the remission induction of GMA in patients with active UC. METHODS This multicenter retrospective cohort study included patients with UC underwent GMA in five independent institutions in Japan from January 2011 to July 2021. Factors including concomitant medications associated with clinical remission (CR) were analyzed statistically. RESULT A total of 133 patients were included. Seventy-four patients achieved a CR after GMA. The multivariable analysis revealed that concomitant medication with 5-aminosalicylic acid, Mayo endoscopic subscore (MES), and concomitant medication with immunosuppressors (IMs) remained as predictors of CR after GMA. In the subgroup analysis in patients with MES of 2, concomitant medication with IMs was demonstrated as a significant negative factor of CR after GMA (P = .042, OR 0.354). Seventy-four patients who achieved CR after GMA were followed up for 52 weeks. In the multivariable analysis, the maintenance therapy with IMs was demonstrated as a significant positive factor of sustained CR up to 52 weeks (P = .038, OR 2.214). Furthermore, the rate of sustained CR in patients with biologics and IMs was significantly higher than that in patients with biologics only (P = .002). CONCLUSION GMA was more effective for patients with active UC that relapsed under treatment without IMs. Furthermore, the addition of IMs should be considered in patients on maintenance therapy with biologics after GMA.

Abstract
In Japan, establishing a medical cooperation system for patients with inflammatory bowel disease (IBD) between IBD flagship and local care hospitals is a crucial task. Thus, this retrospective multicenter cohort study aims to examine the actual state of medical treatment in patients with IBD via a questionnaire survey administered to eight dependent institutes in Hokkaido, Japan. The present results clarified the clinical disparities of IBD treatment and hospital function between IBD flagship hospitals and local care hospitals. Moreover, the understanding level of IBD treatment in medical staff was significantly lower in local care than in IBD flagship hospitals. Furthermore, an abounding experience of IBD treatment affected the understanding level of IBD treatment of both medical doctors and staff. These findings indicate that selecting patients with IBD corresponding to disease activity, educational system for the current IBD treatment, and promotion of team medicine with multimedical staff can resolve clinical discrepancies between IBD flagship and local care hospitals. The IBD treatment inequities in Japan will be eliminated with the development of an appropriate medical cooperation system between IBD flagship and local care hospitals.

Abstract
OBJECTIVE The present study aimed to investigate the effects of a 4-week repeated oral intake of a quercetin-containing supplement on allergen-induced reactions and relative subjective symptoms in Japanese adults who complained of discomfort in the eyes and nose. SUBJECTS AND METHODS A randomized, placebo-controlled, double-blind parallel-group study was conducted on 66 subjects (22-78 years old) with allergic symptoms of pollinosis. The subjects were given the test product (200 mg quercetin) or the control product (vehicle) daily for 4 weeks. The Japanese Rhino-conjunctivitis Quality of Life Questionnaire (JRQLQ) scores and other tests were examined in each subject before and after starting the product intake. A new food-grade bioavailable formulation of quercetin, Quercetin phytosome®, was used. RESULTS At 1:4 weeks after the start of the supplement intake, several scores of JRQLQ, including allergic symptoms, such as eye itching, sneezing, nasal discharge, and sleep disorder, were significantly improved in the quercetin-containing supplement group compared with the placebo group. Furthermore, the quality of life of these subjects significantly improved based on the original questionnaire and visual analog scale. Minor notable adverse effects were noted throughout the study. CONCLUSIONS The results indicated that oral intake of quercetin-containing supplements might effectively reduce some allergy symptoms derived from pollinosis.

Abstract
Abstract
This paper presents results of an experimental study on natural convection in the vertical enclosure of a double coaxial cylinder where the inner wall is at constant heat flux. It is the objective of this experiment to understand the basic characteristics of heat transfer under the condition of natural convection coupled with thermal radiation in a vertical enclosure. The range of Rayleigh numbers based on the width of the double coaxial cylinder is set to be 5.6 × 105 < Ra < 1.04 × 108, the radius ratio is 2.73, the aspect ratio is 3.43 (cylinder length divided by annular gap). The heat transfer coefficient of natural convection coupled with thermal radiation was obtained as function of the Rayleigh number, aspect ratio of the enclosure, and temperature of the hot and cold surfaces. The experimental results show that thermal radiation can’t be neglected in analyzing heat transfer of vertical annulus with natural convection. The results provide the basic data for the design and the performance assessment of the future passive cooling system used in a high-temperature engineering test reactor.

Abstract
Heated tobacco products (HTPs) are an emerging class of tobacco goods that claim to have lower health risks than those of smoking combustible tobacco products. In this study, we exposed human lung epithelial cell lines to extracts prepared from HTP aerosols and combustible cigarette smoke to compare cytotoxicity. We focused on the effects of aldehydes present in the aerosols of HTPs at levels close to those in combustible cigarette smoke. Significant toxicity was confirmed for the HTP extract, albeit to a lesser extent than that with the combustible cigarette extract. When redox balance was evaluated by the oxidative loss of low-molecular-weight thiols in the cells, we found that total glutathione (GSH) contents and low-molecular-weight thiol levels were significantly decreased after exposure to the aerosol extract of HTPs. These results indicated that GSH is rapidly consumed during the detoxification of xenobiotics, such as aldehydes from tobacco extracts. Accordingly, exposure to the aerosol extract of HTPs resulted in the enhanced carbonylation of many proteins. In a simple comparison, the results for HTPs were significantly different from those obtained with combustible cigarette smoke, suggesting reduced toxicity of HTPs. However, we found significant and harmful effects after exposing lung epithelial cells to the aerosol extract of HTPs. Thus, a further comprehensive study is needed to clarify the lung damage induced via the long-term inhalation of aerosols from HTPs.

Abstract
Background Granulocyte and monocyte adsorptive apheresis (GMA) is widely used as a remission induction therapy for active ulcerative colitis (UC) patients. However, there are no available biomarkers for predicting the clinical outcome of GMA. We investigated the utility of Fecal calprotectin (FC) as a biomarker for predicting the clinical outcome during GMA therapy in active UC patients. Methods In this multicenter prospective observation study, all patients received 10 sessions of GMA, twice a week, for 5 consecutive weeks. FC was measured at entry, one week, two weeks, and at the end of GMA. Colonoscopy was performed at entry and after GMA. The clinical activity was assessed based on the partial Mayo score when FC was measured. Clinical remission (CR) was defined as a partial Mayo score of ≤ 2 and endoscopic remission (ER) was defined as Mayo endoscopic subscore of either 0 or 1. We analyzed the relationships between the clinical outcome (CR and ER) and the change in FC concentration. Result Twenty-six patients were included in this study. The overall CR and ER rates were 50.0% and 19.2%, respectively. After GMA, the median FC concentration in patients with ER was significantly lower than that in patients without ER (469 mg/kg vs. 3107 mg/kg, p = 0.03). When the cut-off value of FC concentration was set at 1150 mg/kg for assessing ER after GMA, the sensitivity and specificity were 0.8 and 0.81, respectively. The FC concentration had significantly decreased by one week. An ROC analysis demonstrated that the reduction rate of FC (ΔFC) at 1 week was the most accurate predictor of CR at the end of GMA (AUC = 0.852, P = 0.002). When the cut-off value of ΔFC was set at ≤ 40% at 1 week for predicting CR at the end of GMA, the sensitivity and specificity were 76.9% and 84.6%, respectively. Conclusion We evaluated the utility of FC as a biomarker for assessing ER after GMA and predicting CR in the early phase during GMA in patients with active UC. Our findings will benefit patients with active UC by allowing them to avoid unnecessary invasive procedures and will help establish new strategies for GMA.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effects of high tibial osteotomy (HTO) on the biological status of knee osteoarthritis (OA) using joint markers in synovial fluid (SF). METHODS Fifty patients with medial compartmental OA of the knee who underwent opening wedge HTO were enrolled. Paired SF samples from the affected knee and arthroscopic evaluation of articular cartilage were collected at the time of HTO surgery and the time of plate removal (postoperative 17 ± 4 months). The concentrations of the following SF biomarkers were measured: interleukin (IL)-1β, IL-6, IL-8, IL-10, tumour necrosis factor-α, matrix metalloproteinase (MMP)-2, MMP-3, MMP-9, MMP-13, vascular endothelial growth factor (VEGF), and cartilage oligomeric matrix protein (COMP). The Knee Society Score (KSS) and hip-knee-ankle (HKA) angle were assessed before and 2 years after HTO. RESULTS The KSS knee and function scores were significantly improved after HTO (mean changes of 36.4 and 23.7, respectively). The mean HKA angle was altered from mechanical varus (-8.6°) to valgus (5.2°). Concentrations of IL-6, IL-8, MMP-2, MMP-3, MMP-13, VEGF, and COMP in SF were significantly decreased after HTO (mean changes of -49.1%, -30.2%, -31.1%, -26.3%, -30.8%, -42.5%, and -13.7% from preoperative baseline, respectively). The cartilage status was improved in 19 cases (38%) after HTO. However, changes of all biomarkers were not significantly different between subjects with and without an improved cartilage status. CONCLUSIONS SF levels of biochemical markers for cartilage degradation and synovial inflammation were altered after HTO, suggesting an improvement in the OA disease state.

Abstract
Background:Iguratimod (IGU) was started development as new non-steroidal anti-inflammatory drugs (NSAIDs), but it was changed for development as disease modifying antirheumatic drugs (DMARDs) because it showed suppression of inflammatory cytokine and inflammatory parameter which was not to be found in existing NSAIDs in the early stage of pharmacological study of drug efficacy. Although the clinical efficacy and the safety of IGU were already reported, the efficacy for elderly cases was not sufficiently analyzed.Objectives:In this study, we compared the efficacy of IGU in elderly group with the non-elderly group.Methods:190 patients who were able to continuously administer IGU more than three months was included. Cases were divided into two groups. Group A (75 years or older) includes 57 patients, and Group B (younger than 75 years) includes 133 patients. The patients background, the use of methotrexate (MTX) and glucocorticoid, the change of serum CRP, and the DAS28-ESR (before, 6, 12, and 24 months) as an evaluation of the disease activity were compared between two groups. The study protocol was approved by our institutional review board. All the patients were required to give written informed consent.Results:The average age at the beginning of IGU was 79.9±4.1 years old in Group A, and 59.9±10.6 years old in Group B. The average disease duration was 14.8±16.5 year in Group A and 8.5±10.6 year in Group B (p<0.01). Although the rate of concomitant use of MTX was significantly lower in Group A (Group A; 28.1%, Group B; 56.4%), the averaged dose of MTX did not show difference between groups (7.0 and 8.4 mg/week, respectively). Group A showed significantly higher rate of concomitant use of glucocorticoid (56.1%, and 36.1%, respectively), but the averaged dose of glucocorticoid did not show a difference between groups (4.3 and 3.6mg/day, respectively). Similarly, the rate of concomitant use of NSAIDs did not have a difference in two groups. Group A showed significantly higher serum CRP at the beginning of the IGU (Group A; 2.0 mg/dl, Group B; 1.2 mg/dl), but there was no difference after six months. In both groups, serum CRP was significantly decreased when compared at the beginning of IGU. After six months of IGU administration, both groups showed good clinical performance with DAS28-ESR, more than 60% of the cases showed remission or low disease activity. No difference of DAS28-ESR scores between two groups was observed after six months.Conclusion:From the results of this study, the efficacy of IGU for elderly patients was confirmed and did not show differences with non-elderly people. IGU is an inexpensive drug with enough efficacy and thought to be possible substitute for cases with insufficient reaction with other DMARDs.References:[1]Nozaki Y, et al.

Abstract
BACKGROUND Venous thromboembolism (VTE) has been shown to be more frequent in inflammatory bowel disease (IBD) than in the general population in Western studies. However, the actual state of VTE in Asian IBD remains poorly understood. AIMS To reveal the incidence of VTE in IBD patients in Japan. METHODS Eighty-five patients admitted to 3 gastroenterology centers were registered from 2013 to 2018. The incidence of VTE in patients with IBD (n = 42) was prospectively compared to that among patients with other digestive diseases (n = 43). The presence of VTE was surveyed using contrast-enhanced computed tomography and/or ultrasonography at admission and at 1-2 weeks after admission. The patient characteristics and laboratory data of IBD patients with or without VTE were compared to determine the risk factors for VTE. RESULTS The incidence of VTE with IBD was 16.7%, which was significantly more frequent than with other digestive diseases (2.3%; p = 0.0296). In IBD patients, VTE was detected in 6 of 22 patients with ulcerative colitis (27.2%) but in only 1 of 20 patients with Crohn's disease (5.0%). VTE was diagnosed at admission in 4 IBD patients and 2 weeks after admission in 3 IBD patients. The risk factors of VTE in IBD were the presence of an indwelling central venous catheter, a low level of total protein, a low activated partial thromboplastin time, and a high level of fibrinogen degradation products. CONCLUSION VTE was frequently detected in Japanese IBD patients both at and after admission. Adequate screening and prophylaxis for VTE is deemed necessary in IBD.

Abstract
The International Commission on Radiological Protection has substantially reduced the recommended maximum annual eye lens dose for workers. Use of a dedicated eye dosemeter is one method for accurate dose monitoring. The main aim of this study was to yield recommendations for optimal placement of eye dosemeters to estimate the eye dose to interventional cardiology physicians and nurses. A phantom measurement was conducted to simulate typical interventional cardiology procedures. Considering eight X-ray tube angulations, the left side of the head position provide good estimates for physician, and the forehead position provide good estimates for nurse.

Abstract
Objective The objective of this study was to investigate possible differences in
treatment responses between two categories for the onset of lupus
nephritis. Methods We performed a multicentre, retrospective cohort study of class III–V lupus
nephritis patients diagnosed between 1997 and 2014. The renal responses to
initial induction therapy were compared between patients who developed lupus
nephritis within one year from diagnosis of systemic lupus erythematosus
(early (E-) LN) and the remainder (delayed (D-) LN) using the Kaplan–Meier
method. We determined the predictors of renal response as well as renal
flares and long-term renal outcomes using multivariate Cox regression
analyses. Results A total of 107 E-LN and 70 D-LN patients were followed up for a median of
10.2 years. Log-rank tests showed a lower cumulative incidence of complete
response in D-LN compared with E-LN patients. Multivariate analysis
identified D-LN (hazard ratio (HR) 0.48, 95% confidence interval (CI)
0.33–0.70), nephrotic syndrome at baseline, and a chronicity index greater
than 2 as negative predictors of complete response. D-LN patients were more
likely to experience renal flares. D-LN (HR 2.54, 95% CI 1.10–5.83) and
decreased renal function were significant predictors of chronic kidney
disease at baseline. Conclusion D-LN was a predictor of poorer treatment outcomes, in addition to renal
histology and severity of nephritis at lupus nephritis onset.

Abstract
Aims The purpose of this study was to compare two different types of metal-on-metal (MoM) bearing for total hip arthroplasty (THA): one with a large femoral head (38 mm to 52 mm) and the other with a conventional femoral head (28 mm or 32 mm). We compared clinical outcome, blood metal ion levels, and the incidence of pseudotumour in the two groups. Patients and Methods Between December 2009 and December 2011, 62 patients underwent MoM THA with a large femoral head (Magnum group) and 57 patients an MoM THA with a conventional femoral head (conventional group). Clinical outcome was assessed using the Harris Hip score, University of California, Los Angeles (UCLA) activity score and EuroQol-5D (EQ-5D). Blood metal ion levels were measured and MRI scans were analyzed at a minimum of five years postoperatively. Results No acetabular component was implanted with more than 50° of inclination in either group. The Harris Hip Score, UCLA activity score, and EQ-5D improved postoperatively in both groups; no significant clinical differences were noted between the groups. The blood cobalt ion levels in the conventional group continued to rise postoperatively to five years while reaching a plateau at two years postoperatively in the Magnum group. At five years, the mean cobalt ion level of 1.16 μg/l (sd 1.32) in the Magnum group was significantly lower than the 3.77 μg/l (sd 9.80) seen in the conventional group (p = 0.0015). The incidence of moderate to severe pseudotumour was 4.7% in the Magnum group and 20.6% in the conventional group. There were no dislocations in the Magnum group and two in the conventional group. One patient in the Magnum group underwent revision for pseudotumour at 4.7 years postoperatively. Conclusion At five years, a well-positioned large head MoM THA has a significantly lower level of metal ion release and a lower incidence of moderate to severe pseudotumour than a MoM bearing of conventional size.

Abstract
Background/Aims Venous thromboembolism (VTE) is a major extraintestinal manifestation in inflammatory bowel disease (IBD), regarded as an independent risk factor for VTE according to reports from Western countries. However, the incidence and risk factors of VTE in Asian IBD patients are not fully understood. We aimed to reveal the incidence and risk factors of VTE in Japanese IBD inpatients. Methods The incidence of VTE in inpatients with IBD (n=340), gastrointestinal cancers (n=557), and other gastrointestinal diseases (n=569) treated at our hospital from 2009 to 2013 was retrospectively investigated. The characteristics and laboratory data of IBD inpatients with and without VTE were compared in univariate and multivariate analyses. Clinical courses of VTE in IBD were surveyed. Results VTE was detected in 7.1% of IBD inpatients, significantly higher than in gastrointestinal cancer inpatients (2.5%) and inpatients with other gastrointestinal diseases (0.88%). The incidence of VTE in ulcerative colitis (UC) patients (16.7%) was much higher than that in those with Crohn's disease (3.6%). In the univariate analysis, the risk factors were an older age, central venous catheter, prednisolone, surgery, low serum albumin, high serum C-reactive protein and D-dimer. According to a multivariate analysis, >50 years of age and surgery were the only risk factors. The in-hospital mortality rate of IBD inpatients with VTE was 4.2%. Conclusions The incidence of VTE with IBD, especially UC, was found to be high compared with other digestive disease, which was almost equivalent to that of Western countries. The efficacy of prophylaxis needs to be investigated in Asian IBD patients.

UNLABELLED A head-to-head comparison of once-monthly oral bisphosphonates minodronate (MIN) and risedronate (RIS) in patients with rheumatoid arthritis (RA) demonstrated that MIN has the same effect as RIS on increase in bone mineral density (BMD) and a stronger effect on inhibition of bone resorption than RIS, suggesting that MIN is a promising treatment option for osteoporosis patients with RA. INTRODUCTION To evaluate the effect of once-monthly oral MIN in patients with RA, a prospective, randomized, open-label, head-to-head comparison with once-monthly oral RIS was conducted. METHODS A total of 83 patients with RA were randomly assigned to either once-monthly oral MIN 50 mg (n = 42) or once-monthly oral RIS 75 mg (n = 41). Serial BMD and bone turnover markers were measured and compared between the treatment groups. RESULTS BMD (lumbar spine, total hip, femoral neck) increased significantly after 12 months of treatment with MIN (3.8, 2.0, and 2.2%, respectively, P < 0.05) and RIS (3.6, 1.9, and 1.9%, respectively, P < 0.05). There were no significant differences between the treatment groups. Percent changes of bone turnover markers from baseline to 12 months in the MIN group were significantly greater than those in the RIS group (TRACP-5b: - 36.3 vs - 19.3%, P < 0.05; NTX: - 27.1 vs - 17.3%, P < 0.05; BAP: -30.2 vs -19.4%, P < 0.05). CONCLUSIONS The present study of RA patients demonstrated that MIN has the same effect as RIS on increase in BMD and a stronger effect on inhibition of bone resorption than RIS. The results suggest that MIN is a promising treatment option for osteoporosis patients with RA.

Abstract
OBJECTIVE Dry eye, a chronic disease of lachrymal fluid and corneo-conjunctival epithelium, could significantly impact visual function, affects quality of life and work productivity. Beside several conventional treatments, nutritional supplements based on bilberry extract have been identified as effective contributors to eye health. Here, we aim at investigating the bioavailability of a standardized bilberry extract, its ability to alleviate dry eye symptoms and its antioxidant potential. MATERIALS AND METHODS Either bilberry dried standardized extract derived from Vaccinium myrtillus L. fresh frozen fruits (Mirtoselect®) or a highly purified anthocyanin-rich extract, devoid of the non anthocyanin component and supported on maltodextrins, were each orally administrated to 5 male rats. Blood samples were collected at 5, 10, 15, 20, 30, 45, 60, 90, 120 minutes after treatment, processed and analyzed by UV spectrophotometric method. In a parallel analysis, 22 otherwise healthy subjects suffering from dry eye symptoms were enrolled randomly assigned to receive the more bioavailable bilberry extract or placebo. Ophthalmological and clinical examinations including Schirmer's test, pupil constriction, diacron-reactive oxygen metabolites (d-ROMs) test and biological antioxidant potential (BAP) test were performed at inclusion and after the 4-week study period. RESULTS The area under the curve of plasmatic levels of anthocyanosides in rats resulted 202.34±24.23 µg·min/ml for Mirtoselect® and 130.93±4.93 µg·min/ml for the highly purified anthocyanin-rich bilberry extract, notwithstanding the fact that the highly purified anthocyanin-rich extract group received an anthocyanins dosage much higher than the Mirtoselect® group (354 mg/Kg in anthocyanosides vs. 136 mg/Kg in anthocyanosides). 21 subjects, 11 subjects in the bilberry extract (Mirtoselect®) group and 10 subjects in the placebo group completed the clinical study. Schirmer's test values indicating the volume of tear secretion were significantly improved in the bilberry extract group (p=0.019), whereas no significant changes were observed in the placebo group. A subset analysis revealed that Mirtoselect® could be more effective in subjects with higher tendency of dry eye. In terms of antioxidant potential, the bilberry extract produced significant improvement of BAP (p=0.003) and an increase of modified BAP/d-ROMs ratio, an indicator of overall balance between antioxidant potential and oxidative stress. CONCLUSIONS Our results suggested that natural, standardized bilberry extract (Mirtoselect®) is a natural more bioavailable delivery form anthocyanins, suggesting a strong matrix effect exerted by the non-anthocyanin component. Furthermore, it can improve tear secretion and plasmatic antioxidant potential in subjects suffering from DED symptoms.

Abstract
Aims To determine the normal values and usefulness of the C1/4 space available for spinal cord (SAC) ratio and C1 inclination angle, which are new radiological parameters for assessing atlantoaxial instability in children with Down syndrome. Patients and Methods We recruited 272 children with Down syndrome (including 14 who underwent surgical treatment), and 141 children in the control group. All were aged between two and 11 years. The C1/4 SAC ratio, C1 inclination angle, atlas-dens interval (ADI), and SAC were measured in those with Down syndrome, and the C1/4 SAC ratio and C1 inclination angle were measured in the control group. Results The mean C1/4 SAC ratio in those requiring surgery with Down syndrome, those with Down syndrome not requiring surgery and controls were 0.63 (standard deviation (sd) 0.1), 1.15 (sd 0.13) and 1.29 (sd 0.14), respectively, and the mean C1 inclination angles were -3.1° (sd 10.7°), 15.8° (sd 7.3) and 17.2° (sd 7.3), in these three groups, respectively. The mean ADI and SAC in those with Down syndrome requiring surgery and those with Down syndrome not requiring surgery were 9.8 mm (sd 2.8) and 4.3 mm (sd 1.0), and 11.1 mm (sd 2.6) and 18.5 mm (sd 2.4), respectively. Conclusion The normal values of the C1/4 SAC ratio and the C1 inclination angle were found to be about 1.2° and 15º, respectively. Cite this article: Bone Joint J 2016;98-B:1704–10.

Abstract
Bifidobacterium breve and other Gram-positive gut commensal microbes protect the gastrointestinal epithelium against inflammation-induced stress. However, the mechanisms whereby these bacteria accomplish this protection are poorly understood. In this study, we examined soluble factors derived from Bifidobacterium breve and their impact on the two major protein degradation systems within intestinal epithelial cells, proteasomes and autophagy. Conditioned media from gastrointestinal Gram-positive, but not Gram-negative, bacteria activated autophagy and increased expression of the autophagy proteins Atg5 and Atg7 along with the stress response protein heat shock protein 27. Specific examination of media conditioned by the Gram-positive bacterium Bifidobacterium breve (Bb-CM) showed that this microbe produces small molecules (<3 kDa) that increase expression of the autophagy proteins Atg5 and Atg7, activate autophagy, and inhibit proteasomal enzyme activity. Upregulation of autophagy by Bb-CM was mediated through MAP kinase signaling. In vitro studies using C2BBe1 cells silenced for Atg7 and in vivo studies using mice conditionally deficient in intestinal epithelial cell Atg7 showed that Bb-CM-induced cytoprotection is dependent on autophagy. Therefore, this work demonstrates that Gram-positive bacteria modify protein degradation programs within intestinal epithelial cells to promote their survival during stress. It also reveals the therapeutic potential of soluble molecules produced by these microbes for prevention and treatment of gastrointestinal disease.

Abstract
We describe successful treatment of 3 cases of human herpesvirus 6 (HHV-6) encephalitis/myelitis following cord blood transplantation (CBT). Ganciclovir (GCV) (10 mg/kg/day) reduced HHV-6 load to undetectable levels in cerebrospinal fluid (CSF). Early dose reduction in the presence of HHV-6 detectable in CSF resulted in an increased HHV-6 load. GCV was capably shifted to valganciclovir (VGCV) with an almost equivalent concentration. GCV/VGCV may be effective for HHV-6 encephalitis/myelitis after CBT, although HHV-6 load in CSF should be monitored.

Abstract
OBJECTIVES In total hip arthroplasty (THA), the cementless, tapered-wedge stem design contributes to achieving initial stability and providing optimal load transfer in the proximal femur. However, loading conditions on the femur following THA are also influenced by femoral structure. Therefore, we determined the effects of tapered-wedge stems on the load distribution of the femur using subject-specific finite element models of femurs with various canal shapes. PATIENTS AND METHODS We studied 20 femurs, including seven champagne flute-type femurs, five stovepipe-type femurs, and eight intermediate-type femurs, in patients who had undergone cementless THA using the Accolade TMZF stem at our institution. Subject-specific finite element (FE) models of pre- and post-operative femurs with stems were constructed and used to perform FE analyses (FEAs) to simulate single-leg stance. FEA predictions were compared with changes in bone mineral density (BMD) measured for each patient during the first post-operative year. RESULTS Stovepipe models implanted with large-size stems had significantly lower equivalent stress on the proximal-medial area of the femur compared with champagne-flute and intermediate models, with a significant loss of BMD in the corresponding area at one year post-operatively. CONCLUSIONS The stovepipe femurs required a large-size stem to obtain an optimal fit of the stem. The FEA result and post-operative BMD change of the femur suggest that the combination of a large-size Accolade TMZF stem and stovepipe femur may be associated with proximal stress shielding.Cite this article: M.

Abstract
In a randomized phase II study of sorafenib plus hepatic arterial infusion chemotherapy with cisplatin in comparison with sorafenib alone in patients with advanced hepatocellular carcinoma, it yielded favorable overall survival when compared with sorafenib alone. This is the first report of its effectiveness in relation to the overall survival in comparison with that of sorafenib alone in patients with advanced hepatocellular carcinoma. Background Sorafenib (Sor) is acknowledged as a standard therapy for advanced hepatocellular carcinoma (HCC). This trial was conducted to evaluate the effect of addition of hepatic arterial infusion chemotherapy with cisplatin (SorCDDP) to Sor for the treatment of advanced HCC. Patients and methods We conducted a multicenter open-labeled randomized phase II trial in chemo-naïve patients with advanced HCC with Child-Pugh scores of 5–7. Eligible patients were randomly assigned 2:1 to receive SorCDDP (sorafenib: 400 mg bid; cisplatin: 65 mg/m2, day 1, every 4–6 weeks) or Sor (400 mg bid). The primary end point was overall survival. Results A total of 108 patients were randomized (Sor, n = 42; SorCDDP, n = 66). The median survival in the Sor and SorCDDP arms were 8.7 and 10.6 months, respectively [stratified hazard ratio (95% confidence interval), 0.60 (0.38–0.96), P = 0.031]. The median time to progression and the response rate were, respectively, 2.8 months and 7.3% in the Sor arm and 3.1 months and 21.7% in the SorCDDP arm. The adverse events were more frequent in the SorCDDP arm than in the Sor arm, but well-tolerated. Conclusion SorCDDP yielded favorable overall survival when compared with Sor in patients with advanced HCC.

Abstract
Upper gastrointestinal (GI) lesions are frequently reported in Crohn's disease, in which the entire GI tract is affected. In these cases, erosive fissures regularly transversing folds that are longitudinally aligned along the lesser curvature of the gastric body and cardia are described as having a "bamboo joint-like appearance". We designed a blinded experiment in which upper GI imaging without a final diagnosis was checked by three observers to determine the usefulness of the bamboo joint-like appearance in the diagnosis of Crohn's disease. For the three observers, sensitivities of appearance were 30.5%, 56.9%, and 51.4%, while specificities were 99.6%, 98.5%, and 99.3%. Thus, the bamboo joint-like appearance was not useful for the identification of Crohn's disease patients. Nevertheless, patients exhibiting the bamboo joint-like appearance in upper GI imaging should undergo further examination due to the high probability of Crohn's disease.

Abstract
Background/Objective: Eicosapentaenoic acid (EPA) exerts pleiotropic effects on metabolic disorders such as atherosclerosis and dyslipidemia, but its effectiveness in the treatment of type 2 diabetes mellitus remains controversial. Methods: We examined the antidiabetic effect of EPA in insulin receptor mutant (InsrP1195L/+) mice that exhibit high-fat diet (HFD)-dependent hyperglycemia. Results: EPA supplementation was found to alleviate hyperglycemia of InsrP1195L/+ mice fed HFD (InsrP1195L/+/HFD mice), which was accompanied by amelioration of increased gluconeogenesis and impaired insulin signaling, as assessed by glucose-6-phosphatase (G6pc) expression on refeeding and insulin-induced phosphorylation of Akt in the liver, respectively. We found that serum levels of adiponectin, the antidiabetic adipokine, were decreased by HFD along with the body weight gain in InsrP1195L/+ mice but not in wild-type mice, suggesting that InsrP1195L/+ mice are prone to hypoadiponectinemia in response to obesity. Interestingly, the blood glucose levels of InsrP1195L/+ mice were in reverse proportion to their serum adiponectin levels and EPA supplementation ameliorated their hyperglycemia in conjunction with the restoration of hypoadiponectinemia. Conclusions: EPA exerts an antidiabetic effect in InsrP1195L/+/HFD mice, an HFD-sensitive, insulin-resistant animal model, possibly through its action against hypoadiponectinemia.

Abstract
As a result of recent advances in endoscopic therapeutic technology, the number of endoscopic resections carried out in the treatment of early colorectal carcinomas with little risk of lymph node metastasis has increased. There are no reports of lymph node metastasis in intramucosal (Tis) carcinomas, whereas lymph node metastasis occurs in 6.8-17.8% of submucosal (T1) carcinomas. Three clinical guidelines have been published in Japan and the management strategy for early colorectal tumors has been demonstrated. According to the 2014 Japanese Society for Cancer of the Colon and Rectum (JSCCR) Guidelines for the Treatment of Colorectal Cancer, additional surgery should be done in cases of endoscopically resected T1 carcinoma with a histologically diagnosed positive vertical margin. Additional surgery may also be considered when one of the following histological findings is detected: (i) SM invasion depth ≥1000 µm; (ii) histological type por., sig., or muc.; (iii) grade 2-3 tumor budding; and (iv) positive vascular permeation. A resected lesion that is histologically diagnosed as a T1 carcinoma without any of the above-mentioned findings can be followed up without additional surgery. As for the prognosis of endoscopically resected T1 carcinomas, the relapse ratio of approximately 3.4% (44/1312) is relatively low. However, relapse is associated with a poor prognosis, with 72 cancer-related deaths reported out of 134 relapsed cases (54%). A more detailed stratification of the lymph node metastasis risk after endoscopic resection for T1 carcinomas and the prognosis of relapsed cases will be elucidated through prospective studies. Thereafter, the appropriate indications and safe and secure endoscopic resection for T1 carcinomas will be established.

Abstract
Diagnosis and treatment of bone metastasis requires various types of measures, specialists and caregivers. To provide better diagnosis and treatment, a multidisciplinary team approach is required. The members of this multidisciplinary team include doctors of primary cancers, radiologists, pathologists, orthopaedists, radiotherapists, clinical oncologists, palliative caregivers, rehabilitation doctors, dentists, nurses, pharmacists, physical therapists, occupational therapists, medical social workers, etc. Medical evidence was extracted from published articles describing meta-analyses or randomised controlled trials concerning patients with bone metastases mainly from 2003 to 2013, and a guideline was developed according to the Medical Information Network Distribution Service Handbook for Clinical Practice Guideline Development 2014. Multidisciplinary team meetings are helpful in diagnosis and treatment. Clinical benefits such as physical or psychological palliation obtained using the multidisciplinary team approaches are apparent. We established a guideline describing each specialty field, to improve understanding of the different fields among the specialists, who can further provide appropriate treatment, and to improve patients’ outcomes.

Abstract
Many pharmaceutical agents not only require microbial metabolism for increased bioavailability and bioactivity, but also have direct effects on gut microbial assemblage and function. We examined the possibility that these actions are not mutually exclusive and may be mutually reinforcing in ways that enhance long‐term of these agents. Daikenchuto, TU‐100, is a traditional Japanese medicine containing ginseng. Conversion of the ginsenoside Rb1 (Rb1) to bioactive compound K (CK) requires bacterial metabolism. Diet‐incorporated TU‐100 was administered to mice over a period of several weeks. T‐RFLP and 454 pyrosequencing were performed to analyze the time‐dependent effects on fecal microbial membership. Fecal microbial capacity to metabolize Rb1 to CK was measured by adding TU‐100 or ginseng to stool samples to assess the generation of bioactive metabolites. Levels of metabolized TU‐100 components in plasma and in stool samples were measured by LC‐MS/MS. Cecal and stool short‐chain fatty acids were measured by GC‐MS. Dietary administration of TU‐100 for 28 days altered the gut microbiota, increasing several bacteria genera including members of Clostridia and Lactococcus lactis. Progressive capacity of microbiota to convert Rb1 to CK was observed over the 28 days administration of dietary TU‐100. Concomitantly with these changes, increases in all SCFA were observed in cecal contents and in acetate and butyrate content of the stool. Chronic consumption of dietary TU‐100 promotes changes in gut microbiota enhancing metabolic capacity of TU‐100 and increased bioavailability. We believe these findings have broad implications in optimizing the efficacy of natural compounds that depend on microbial bioconversion in general.

Abstract
BACKGROUND AND AIMS No endoscopic examination has been able to evaluate severity of ulcerative colitis (UC) by quantification. This prospective study investigated the efficacy of quantifying autofluorescence imaging (AFI) to assess the severity of UC, which captures the fluorescence emitted from intestinal tissue and then quantifies the intensity using an image-analytical software program. MATERIALS AND METHODS Eleven endoscopists separately evaluated 135 images of conventional endoscopy (CE) and AFI from a same lesion. A CE image corresponding to Mayo endoscopic subscore 0 or 1 was defined as being inactive. The fluorescence intensities of AFI were quantified using an image-analytical software program (F index; FI). Active inflammation was defined when Matts' histological grade was 2 or more. A cut-off value of the FI for active inflammation was determined using a receiver operating characteristic (ROC) analysis. The inter-observer consistency was calculated by unweighted kappa statistics. RESULTS The correlation coefficient for the FI was inversely related to the histological severity (r = -0.558, p < 0.0001). The ROC analysis showed that the optimal cut-off value for the FI for active inflammation was 0.906. The average diagnostic accuracy of the FI was significantly higher than those of the CE (84.7 vs 78.5 %, p < 0.01). The kappa values for the inter-observer consistency of CE and the FI were 0.60 and 0.95 in all participants, 0.53 and 0.97 in the less-experienced endoscopists group and 0.67 and 0.93 in the expert group, respectively. CONCLUSIONS The quantified AFI is considered to be an accurate and objective indicator that can be used to assess the activity of ulcerative colitis, particularly for less-experienced endoscopists.

Abstract
The clinical importance of Crohn's disease (CD)-specific lesions in the upper gastrointestinal tract (upper GIT) has not been sufficiently established. The aim of this case-control study is to investigate the characteristic findings of CD in the upper GIT. In 2740 patients who underwent gastroduodenoscopy at Asahikawa Medical University between April 2011 and December 2012, 81 CD patients, 81 gender- and age-matched non-IBD patients, and 66 ulcerative colitis (UC) patients were investigated in the present study. (1) The diagnostic ability and odds ratio of each endoscopic finding (a bamboo joint-like appearance in the cardia, erosions, and/or ulcers in the antrum, notched signs, and erosions and/or ulcers in the duodenum) were compared between the CD and non-IBD patients or UC patients. (2) The interobserver agreement of the diagnosis based on the endoscopic findings was evaluated by 3 experienced and 3 less-experienced endoscopists. The incidence of detecting a bamboo joint-like appearance, notched signs, and erosions and/or ulcers in the duodenum was significantly higher in the CD patients than in the non-IBD and UC patients. In addition, the diagnostic ability and odds ratio of a bamboo joint-like appearance for CD were higher than those for the other findings. Kendall's coefficients of concordance in the group of experienced and less-experienced endoscopists were relatively high for a bamboo joint-like appearance (0.748 and 0.692, respectively). A cardiac bamboo joint-like appearance is a useful finding for identifying high-risk groups of CD patients using only gastroduodenoscopy.

Abstract
Inflammatory bowel disease frequently causes intestinal obstruction because of extensive fibrosis. This study investigated whether polyphosphate (poly P), an active molecule derived from Lactobacillus brevis, could improve the fibrosis in a model of chronic colitis. In this study, dextran sodium sulfate (DSS)-induced chronic colitis models and trinitrobenzene sulfonic acid (TNBS)-induced colitis models were used as models of fibrosis. To clarify the mechanism responsible for the observed effects, Caco-2/brush border epithelial (BBE) and naive T helper lymphocyte (THP)-1 cells were treated with lipopolysaccharide (LPS) to induce inflammation. Non-cancer human colon fibroblast (CCD-18) cells were treated with transforming growth factor beta 1 (TGF-β1) to induce fibrosis. The expression levels of fibrosis- and inflammation-associated molecules were evaluated by both a Western blotting analysis and reverse transcriptase-polymerase chain reaction (RT-PCR). The histologic inflammation and fibrosis were significantly improved in the group administered poly P in both the DSS and TNBS colitis models. The levels of interleukin 1β (IL-1β) and tumor necrosis factor α (TNF-α) were significantly decreased by poly P treatment. The expression levels of TGF-β1 and collagens in the colitis mice were decreased by poly P. The LPS-induced expressions of IL-1β and TGF-β1 in Caco-2/BBE cells and of TNF-α in THP-1 cells were reduced by poly P treatment. Poly P did not affect the expression of collagens and connective tissue growth factor in the CCD-18 cells. In conclusion, poly P suppresses intestinal inflammation and fibrosis by downregulating the expression of inflammation- and fibrosis-associated molecules in the intestinal epithelium. The administration of poly P is therefore a novel option to treat fibrosis because of chronic intestinal inflammation.

Abstract
Multiple myeloma is characterized by the neoplastic proliferation of a single clone of plasma cells producing a monoclonal protein. However, the involvement of pancreas is a rare event. We herein report a rare case of pancreatic plasmacytoma, which was detected before the diagnosis of multiple myeloma.An 83-year-old male was referred to our hospital for further evaluation of obstructive jaundice and a pancreatic mass. A contrast-enhanced computed tomography (CT) scan revealed solid masses with homogenous enhancement in the pancreatic head and retroperitoneum. The histological findings of the retroperitoneal mass obtained by CT-guided biopsy showed multiple sheets of atypical plasma cells, which were positively immunostained for CD79a, CD138, and the κ light chain. Serum immunoelectrophoresis detected M-component of immunoglobulin A-κ, and the histological findings of the bone marrow revealed an abnormally increased number of atypical plasma cells with irregular nuclei and cytoplasmic vacuolation. The patient was therefore diagnosed to have multiple myeloma involving the pancreas and retroperitoneum. Although chemotherapy was performed, the patient died 6 months after the diagnosis.The pancreatic plasmacytoma was detected before the multiple myeloma in the present case. It is difficult to diagnose a pancreatic plasmacytoma without a history of multiple myeloma and related disease.

Abstract
In this study we used subject-specific finite element analysis to investigate the mechanical effects of rotational acetabular osteotomy (RAO) on the hip joint and analysed the correlation between various radiological measurements and mechanical stress in the hip joint. We evaluated 13 hips in 12 patients (two men and ten women, mean age at surgery 32.0 years; 19 to 46) with developmental dysplasia of the hip (DDH) who were treated by RAO. Subject-specific finite element models were constructed from CT data. The centre–edge (CE) angle, acetabular head index (AHI), acetabular angle and acetabular roof angle (ARA) were measured on anteroposterior pelvic radiographs taken before and after RAO. The relationship between equivalent stress in the hip joint and radiological measurements was analysed. The equivalent stress in the acetabulum decreased from 4.1 MPa (2.7 to 6.5) pre-operatively to 2.8 MPa (1.8 to 3.6) post-operatively (p < 0.01). There was a moderate correlation between equivalent stress in the acetabulum and the radiological measurements: CE angle (R = –0.645, p < 0.01); AHI (R = –0.603, p < 0.01); acetabular angle (R = 0.484, p = 0.02); and ARA (R = 0.572, p < 0.01). The equivalent stress in the acetabulum of patients with DDH decreased after RAO. Correction of the CE angle, AHI and ARA was considered to be important in reducing the mechanical stress in the hip joint. Cite this article: Bone Joint J 2015;97-B:492–7.

Abstract
BACKGROUND EMR and endoscopic submucosal dissection (ESD) are used frequently to remove colon neoplasms. However, the predominance of these procedures has not yet been thoroughly explored. OBJECTIVE To compare the efficacy and adverse events related to EMR with those related to ESD for colon neoplasms. DESIGN A meta-analysis of 8 studies published between 2005 and 2013. SETTING Multicenter review. PATIENTS Patients from 8 studies yielding 2299 lesions. INTERVENTIONS EMR or ESD. MAIN OUTCOME MEASUREMENTS En bloc resection, curative resection, recurrence, and adverse events. RESULTS The pooled odds ratios (OR) (OR [95% confidence interval]) for the tumor size, length of the procedure, en bloc resection, curative resection, recurrence, additional surgery, delayed bleeding, and perforation by ESD versus EMR were 7.38 (6.42-8.34), 58.07 (36.27-79.88), 6.84 (3.30-14.18), 4.26 (3.77-6.57), 0.08 (0.04-0.17), 2.16 (1.16-4.03), 0.85 (0.45-1.60), and 4.96 (2.79-8.85), respectively. LIMITATIONS This analysis included only nonrandomized studies. CONCLUSION The size of the tumor and rate of en bloc resection and curative resection were higher, and the rate of recurrence was lower in the ESD group versus the EMR group. However, in the ESD group, the procedure was longer, and the rate of additional surgery and perforation was higher, suggesting that the indications for ESD should therefore be rigorously determined in order to avoid such problems.

Abstract
BACKGROUND No method for sufficiently making the differential diagnosis of intestinal lymphoma resembling lymphoid hyperplasia (LH) on endoscopy has yet been established. OBJECTIVE The aim of this study was to evaluate the usefulness of narrow-band imaging (NBI) in diagnosing intestinal lymphoma. DESIGN Prospective study. SETTING Single-center study. PATIENTS Sixty-one patients with primary or systemic lymphoma were enrolled in this study. INTERVENTIONS The terminal ileum and entire colon were observed by using conventional endoscopy. NBI was subsequently performed when small polypoid lesions were detected. A decrease in the number of vascular networks (DVNs) and the presence of irregular vessels on the surface of the epithelia were defined as characteristic findings of intestinal lymphoma. The diagnostic accuracy of these 2 findings in distinguishing intestinal lymphoma from LH was examined. MAIN OUTCOME MEASUREMENTS The ability to use NBI to distinguish intestinal lymphoma from LH. RESULTS Two hundred ninety-four small polypoid lesions, including 59 lymphomas and 235 LH lesions, were detected. The rates of detecting DVNs and the presence of irregular vessels were significantly higher in the lymphoma samples (81.4% and 62.7%) than in the LH samples (25.5% and 4.7%). Based on these findings, the diagnostic accuracy, sensitivity, specificity, and positive and negative predictive values for differentiating intestinal lymphoma from LH were 88.8%, 62.7%, 95.3%, 77.1%, and 91.1%, respectively, which are significantly higher than those of conventional endoscopy. LIMITATIONS Single-center study. CONCLUSION DVNs and the presence of irregular vessels on NBI are thus considered to be useful findings for differentiating intestinal lymphoma from benign LH.

Abstract
Hybrid CT/angiography (angiography) system and C-arm cone beam CT provide cross-sectional imaging as an adjunct to angiography. Current interventional oncological procedures can be conducted precisely using these two technologies. In this article, several cases using a hybrid CT/angiography system are shown first, and then the advantages and disadvantages of the hybrid CT/angiography and C-arm cone beam CT are discussed with literature reviews.
