Abstract
OBJECTIVES Although tight control of rheumatoid arthritis (RA) has been achieved through the development of effective medication, surgical intervention is still required for a certain subpopulation of patients. To examine the systemic effects of orthopaedic surgery, we evaluated improvements in disease activity, daily function, and medication after surgery. METHOD A prospective cohort study was conducted in 196 cases of elective orthopaedic surgery in 150 patients with RA from January 2011 to March 2014 in our institution. The 28-joint count Disease Activity Score based on erythrocyte sedimentation rate (DAS28-ESR) and modified Health Assessment Questionnaire (mHAQ) scores just before surgery and at 6 and 12 months after surgery were examined prospectively. Concomitant medications were also investigated. RESULTS Significant improvement was seen in the DAS28-ESR and mHAQ scores for replacement surgery in both the upper and lower extremities, and for arthroplasty/arthrodesis in the upper extremities at the 12-month follow-up. Partial mHAQ scores for the lower extremities were significantly reduced in lower replacement surgery, and partial mHAQ scores for the upper extremities were significantly reduced in upper arthroplasty/arthrodesis surgery. Although the use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) did not decrease after surgery, the dose of prednisolone (PSL) decreased significantly at 12 months after surgery, especially in the well-controlled group and in surgical procedures in the lower extremities. CONCLUSIONS Elective orthopaedic surgery improves both systemic disease activity and general functional impairment. Orthopaedic surgery is effective in reducing the amount of medication required postoperatively.

Abstract
UNLABELLED The relationship between periarticular osteoporosis in the distal forearm and joint destruction or functional impairment in patients with rheumatoid arthritis (RA) is not sufficiently elucidated. From a single institutional cohort study, we found a strong correlation between periarticular forearm bone mineral density (BMD) and joint destruction or functional impairment. INTRODUCTION This study was conducted to investigate (1) the difference between various periarticular regions of interest (ROIs) of BMD of the forearm, (2) the correlation between periarticular forearm BMD and joint destruction and physical function, (3) the independent variables for predicting BMD of the forearm, and (4) the forearm BMD of different ROIs in the early stage of RA. METHODS We conducted a cross-sectional study in an RA cohort. Measurements included BMD of the distal forearm, joint destruction of the hands assessed by modified total Sharp score (mTSS), functional impairment assessed by a health assessment questionnaire (HAQ), and other clinical data. Variables affecting the forearm BMD values were analyzed by correlation and stepwise regression analyses. RESULTS Of the 405 patients enrolled in the present study, 370 (average age; 62.9 years) were identified as having definite RA with a complete set of data. BMD in the distal end of the forearm (BMDud) was significantly reduced compared with that in the distal third of the forearm (BMD1/3). In a stepwise regression analysis, the mTSS in BMD1/3 was an independent predicting variable, while age and partial HAQ scores associated with the upper extremity were common independent variables in BMDud and BMD1/3. BMDud was significantly less than BMD1/3, even in patients with a short duration of the disease. BMD1/3 was significantly less in non-remission group compared with that in remission group in patients with a short duration of the disease. CONCLUSION Periarticular BMD in the distal forearm is closely correlated with joint destruction and functional impairment in RA. Periarticular BMD in the distal forearm may be already reduced at the clinical manifestation of the disease.

Abstract
AIM To investigate the relationship between plasma betatrophin concentrations and insulin secretion capacity in people with Type 2 diabetes. METHODS Glucagon stimulation tests (1 mg) were performed in 70 people with Type 2 diabetes after an overnight fast. Plasma betatrophin concentrations were measured using an enzyme-linked immunosorbent assay. Insulin secretion capacity was evaluated by measuring increments of C-peptide concentration in response to glucagon stimulation, and creatinine clearance was determined by comparing creatinine concentrations in serum and 24-h urine samples. RESULTS Plasma betatrophin concentrations were positively correlated with duration of Type 2 diabetes (r = 0.34, P = 0.003), and negatively correlated with increments of C-peptide concentration (r = 0.37, P = 0.001) and creatinine clearance (r = 0.37, P = 0.001). The correlation with increments of C-peptide concentration remained significant after adjustment for age and duration of Type 2 diabetes (r = 0.25, P = 0.037). Multivariate analysis identified age and increments of C-peptide concentration as independent factors associated with plasma betatrophin levels. CONCLUSION Plasma betatrophin levels inversely correlate with insulin secretion capacity, suggesting that betatrophin levels are regulated by insulin secretion capacity in humans.

Abstract
BACKGROUND Chemotherapeutic regimens for elderly patients with metastatic colorectal cancer (mCRC), such as bevacizumab combined with 5-fluorouracil (5-FU) and leucovorin, often exclude oxaliplatin and irinotecan owing to the risk of toxicity. However, treatment with infusional 5-fluorouracil and leucovorin requires percutaneous port-catheter placement and other precautions, causing unnecessary stress for patients as well as healthcare workers. METHODS We conducted a phase II study to evaluate the efficacy and safety of bevacizumab plus S-1 in elderly patients with previously untreated mCRC. Bevacizumab was given intravenously every two weeks, and S-1 was administered orally on days 1-28 of a 42-day cycle. The primary end-point was progression-free survival (PFS). The secondary end-points were time to treatment failure, response rate (RR), overall survival (OS), treatment completion status and safety. RESULTS From October 2007 through March 2010, 56 patients were enroled. The median PFS was 9.9months, the median OS was 25.0months, and the RR was 57%. The main adverse events of grade 3 or higher were hypertension (11%), diarrhoea (9%) and neutropenia (7%). CONCLUSION Our results suggest that combination chemotherapy with S-1 and bevacizumab can be administered safely and continuously on an outpatient basis and is therapeutically effective in elderly patients with mCRC.

Abstract
AIM The aim of this study was to determine the correlation between the growth hormone (GH)-insulin-like growth factor-I (IGF-I) axis and glucose intolerance in acromegaly during the early postoperative period. SUBJECTS AND METHODS The study included 20 patients with acromegaly caused by GH-secreting pituitary adenoma who received transsphenoidal surgery in our hospital. Glucose tolerance was evaluated with oral glucose tolerance tests (OGTTs) performed during pre- and early postoperative periods (9 [7-18] days after surgery). Homeostasis model assessment of insulin resistance (HOMA-IR) and insulinogenic index (IGI) were calculated, and correlation analyses were performed between these values and the GH-IGF-I axis. Patients were divided according to postoperative changes of the axis, and glucose tolerance was compared between the groups. RESULTS In preoperative OGTTs, nine patients had impaired glucose tolerance and two had diabetes mellitus patterns. Postoperatively, significant reduction was observed both in fasting plasma glucose levels (p<0.01) and in HOMA-IR (p<0.01), whereas IGI showed no significant change. HOMA-IR was significantly correlated with serum IGF-I levels both before (r=0.83, p<0.01) and after (r=0.57, p<0.01) surgery, although it was not correlated with serum GH levels. Patients who achieved more than 50% postoperative reduction in serum IGF-I levels showed significant improvement in OGTTs results (p<0.05). CONCLUSIONS In patients with acromegaly, serum IGF-I levels, but not GH levels, were significantly correlated with insulin resistance. Early postoperative improvement of glucose tolerance is observed in patients who achieved postoperative reduction in serum IGF-I levels.

Abstract
BACKGROUND Recently, it has been reported that the incidence of primary aldosteronism (PA) among patients with hypertension is much more frequent than previously reported. AIM In the present study, we investigated the frequency and features of PA associated with subclinical Cushing syndrome (SCS). MATERIAL AND METHODS Subjects included consecutive patients (no.=39) who were diagnosed as PA and performed adrenal venous sampling between 2003 and 2011 in our institute. RESULTS In 39 subjects who were diagnosed as PA, 29 patients were operated and 5 cases (12.8%) showed no suppression in low-dose dexamethasone suppression test. Four cases of them were demonstrated to be associated with SCS, and one was associated with overt Cushing syndrome (CS). Post-operatively, 3 cases received replacement therapy of hydrocortisone, while others did not. Pathological findings indicated the diagnosis of aldosterone-producing adenoma in 4 cases associated with SCS, and of idiopathic hyperaldosteronismin in one case associated with overt CS. In all 5 cases, immunohistochemical analysis demonstrated the immunoreactivities of both 3βHSD and P450c17 in the adrenocortical tumors, the marked cortical atrophy in the zona fasciculata and reticularis, the decreased dehydroepiandrosterone sulfotransferase expression, and suppression of hypothalamo- pituitary-adrenal axis indicating the autonomous secretion of cortisol from the tumor. CONCLUSIONS The present study suggests that PA is frequently associated with SCS with prevalence of more than 10%, justifying the routine examinations for SCS in PA cases.

Abstract
BACKGROUND Since the best chemotherapy regimen for each patient with advanced gastric cancer is uncertain, we aimed to identify molecular prognostic or predictive biomarkers from biopsy specimens in JCOG9912, a randomized phase III trial for advanced gastric cancer. PATIENTS AND METHODS Endoscopic biopsy specimens from primary lesions were collected in 445 of 704 randomized patients in JCOG9912. We measured the mRNA expression of excision repair cross-complementing group 1 (ERCC1), thymidylate synthase, dihydropyrimidine dehydrogenase, and five other genes, then, categorized them into low and high groups relative to the median, and examined whether gene expression was associated with efficacy end point. RESULTS Multivariate analyses showed that high ERCC1 expression [HR 1.37; 95% confidence interval (CI) 1.08-1.75; P = 0.010], performance status ≥ 1 (HR 1.45; 95% CI 1.13-1.86; P = 0.004), and number of metastatic sites ≥ 2 (HR 1.66; 95% CI 1.28-1.86; P < 0.001) were associated with a poor prognosis, and recurrent disease (versus unresectable; HR 0.75; 95% CI 0.56-1.00; P = 0.049) was associated with a favorable prognosis. None of these molecular factors were a predictive marker for choosing irinotecan plus cisplatin or 5-fluorouracil rather than S-1. CONCLUSION These correlative analyses suggest that ERCC1 is an independent prognostic factor for overall survival in the first-line treatment of gastric cancer.

Abstract
AIMS It has been recognized that blood pressure shows a seasonal variation, but it remains unknown whether diabetic nephropathy shows a seasonal variation. In the present study, we investigated the change in urinary albumin/creatinine ratio in relation to the season in Japanese patients with Type 2 diabetes. METHODS A total of 430 subjects (275 male, 155 female) with Type 2 diabetes and early nephropathy (defined by UACR 30-300 mg/g creatinine) were included. One year was divided into four seasons and each season was defined as winter (December-February), spring (March-May), summer (June-August), and fall (September-November), and systolic and diastolic blood pressure, serum creatinine levels, and the urinary albumin/creatinine ratio were examined. The estimated glomerular filtration rate was also calculated and evaluated. RESULTS The mean age (± SE) was 64.8 ± 0.8 years. The mean systolic blood pressure was significantly higher in winter than in summer (136 ± 0.68 vs. 133 ± 0.68 mmHg, P < 0.001). The urinary albumin/creatinine ratio showed a significantly higher value in winter than in summer (72.8 ± 4.4 vs. 54.6 ± 3.4 mg/g creatinine, P < 0.001). The curve of seasonal variation of this ratio showed a similar change to that of systolic blood pressure. No significant seasonal variation was observed in estimated glomerular filtration rate and diastolic blood pressure. CONCLUSIONS Our results suggest that there is a hitherto unknown seasonal variation in the urinary albumin/creatinine ratio, and that it may be necessary to consider this seasonal change, especially when performing an intervention study of nephropathy.
