Abstract
INTRODUCTION Preference for quality of life is important in deciding the treatment strategy for patients with type 2 diabetes mellitus. This study aimed to assess the effect of omarigliptin on patients' psychological attitudes and responses compared with daily dipeptidyl peptidase-4 inhibitors (DPP4is) by measuring the burden of pharmacotherapy using the Diabetic Treatment Burden Questionnaire (DTBQ). METHODS Patients with type 2 diabetes mellitus who were taking daily DPP-4is were enrolled and randomized to a group that switched to omarigliptin or a group that continued daily DPP4is and were monitored for 12 weeks. The primary endpoint was the change in the DTBQ score from baseline to week 12. The secondary endpoints included changes in blood test results, medication preferences and medication adherence. RESULTS The DTBQ total score significantly decreased from baseline to week 12 in both groups; however, no significant intergroup differences were observed. The DTBQ subscale, implementation and flexibility burden scores significantly decreased in the group that switched to omarigliptin, although no significant intergroup difference in the change was observed. DTBQ scores and medication preferences were associated with improvements in the DTBQ scores. CONCLUSION Although this study failed to demonstrate the improvement of DTBQ total score by switching from daily DPP4is to omarigliptin compared with continuing the daily DPP4is, the DTBQ subscale score implementation and flexibility burden score were significantly improved only in the group that switched to omarigliptin, suggesting the possibility of switching from daily DPP4is to omarigliptin to decrease the patients' medication burden.

Abstract
Cardiomyopathy is the leading cause of death in patients with muscular dystrophy (MD). Tranilast, a widely used anti-allergic drug, has displayed inhibitory activity against the transient receptor potential cation channel subfamily V member 2 and improved cardiac function in MD patients. To identify urinary biomarkers that assess improved cardiac function after tranilast administration, we performed a urinary metabolomic study focused on oxidative fatty acids. Accompanying the clinical trial of tranilast, urine specimens were collected over 24 weeks from MD patients with advanced heart failure. Urinary levels of tetranor-PGDM (tetranor-prostaglandin D metabolite), a metabolite of prostaglandin D2, significantly decreased 12 weeks after tranilast administration and were correlated with BNP. These results suggest that prostaglandin-mediated inflammation, which increases with the pathological progression of heart failure in MD patients, was attenuated. Urinary prostaglandin E3 (PGE3) levels significantly increased 4 weeks after tranilast administration. There were positive correlations between the urinary levels of PGE3 and 8-hydroxy-2'-deoxyguanosine, an oxidative stress marker. High PGE3 levels may have a protective effect against cardiomyopathy in MD patients with high oxidative stress. Although further validation studies are necessary, urinary tetranor-PGDM and PGE3 levels may help the current understanding of the extent of advanced heart failure in patients with MD after tranilast administration.

Abstract
We assessed the prescription patterns of oral antidiabetic drugs in Japanese patients with type 2 diabetes between 2002 and 2020 using data from the Computerized Diabetes Care database. Among 172,960 patients treated with oral antidiabetic drugs, both the sulfonylurea prescription rate and dose decreased from 2002 to 2020. Prescriptions of biguanides, dipeptidyl peptidase-4 inhibitors and sodium-glucose cotransporter 2 inhibitors increased; their dose and dose frequency remained relatively stable. Trends in oral antidiabetic drug prescriptions changed over time, reflecting guideline recommendations and existing evidence.

Abstract
Recently, good postoperative visual acuity has been reported using surgical removal of hard exudates (HEs) through an intentional macular hole (iMH). We report 3 cases of subfoveal HE secondary to diabetic maculopathy (DM) treated with HE removal via an iMH. Pars plana vitrectomy (PPV) was performed in three eyes of 3 patients with subfoveal HE secondary to DM. In all eyes, after PPV, internal limiting membrane (ILM) peeling of the lower half was performed within the range of papilla diameter 2 centered on the fovea, leaving the upper half for subsequent inverted ILM flap technique. Then, by grabbing the inner layer of the fovea using ILM forceps, an iMH was created. The HE was then flushed from the iMH with a balanced salt solution as much as possible. Finally, the inverted ILM flap technique was performed using the upper half of the ILM that was left during the previous maneuver. At the end of the surgery, the eyes were flushed with 50 mL of 20% sulfur hexafluoride (SF6) after the fluid-air exchange of the vitreous cavity. After surgery, HE was adequately removed, iMH was completely closed, and visual acuity improved in all eyes. This surgical procedure did not cause a central scotoma but rather improved the central sensitivity of the visual field in all eyes. No serious surgery-related complications occurred. In conclusion, HE removal via an iMH hole can be one of the treatment options for patients with subfoveal HE secondary to DM.

Abstract
We report a 71-year-old woman who presented with paresthesia, progressive weakness, difficulty walking, diarrhea, and bladder dysfunction one week after she received the BNT162b2 COVID-19 vaccine. Her neurological signs and symptoms gradually worsened up to 27 days after onset, after which her weakness slowly improved without immunotherapy. Analysis of serial cerebrospinal fluid specimens showed gradually increasing protein levels. Results of a nerve conduction study suggested functional axonal disturbance. The clinical findings together with the monophasic clinical course were consistent with Guillain-Barré syndrome. Her previous history was negative for symptomatic infection. Serological and bacterial tests, including the presence of anti-glycolipid antibodies, were negative for prior infection. Few cases have been reported on the development of Guillain-Barré syndrome after the BNT162b2 vaccine. Our patient's syndrome was characterized by atypical proximal weakness of the dominant lower limb. (Received January 28, 2022; Accepted April 4, 2022; Published August 1, 2022).

Abstract
Hereditary myopathy with early respiratory failure (HMERF) is caused by titin A-band mutations in exon 344 and is considered quite rare. Respiratory insufficiency can be the sole symptom in the disease course. We herein report the first Japanese HMERF patient with a p.P31732L mutation in titin. The patient manifested respiratory failure and mild weakness of the neck flexor muscle at 69 years old and showed fatty replacement of the bilateral semitendinosus muscles on muscle imaging. Our case indicates that HMERF with a heterozygous p.P31732L mutation should be included in the differential diagnosis of muscular diseases presenting with early respiratory failure.

Abstract
INTRODUCTION We investigated trends in the proportion of diabetes treatment and glycemic control, which may be altered by recent advances in insulin and non-insulin drugs, in Japanese patients with type 2 diabetes. RESEARCH DESIGN AND METHODS A serial cross-sectional study was performed using a multicenter large-population database from the Japan Diabetes Clinical Data Management study group. Patients with type 2 diabetes who attended clinics belonging to the study group between 2002 and 2018 were included to examine trends in glycated hemoglobin A1c (HbA1c) by treatment group using multivariable non-linear regression model. RESULTS The proportion of patients with insulin only decreased from 15.0% to 3.6%, patients with insulin+non-insulin drugs increased from 8.1% to 15.1%, patients with non-insulin drugs increased from 50.8% to 67.0%, and those with no drugs decreased from 26.1% to 14.4% from 2002 to 2018, respectively. The HbA1c levels of each group, except for no drugs, continued to decrease until 2014 (unadjusted mean HbA1c (%) from 2002 to 2014: from 7.89 to 7.45 for insulin only, from 8.09 to 7.63 for insulin+non-insulin, and from 7.51 to 6.98 for non-insulin) and remained unchanged thereafter. Among insulin-treated patients, use of human insulin decreased, use of long-acting analog insulin increased, and concomitant use of non-insulin drugs increased (from 35.1% in 2002 to 80.9% in 2018), which included increased use of dipeptidyl peptidase 4 inhibitors, sodium-glucose cotransporter 2 inhibitors, and glucagon-like peptide 1 receptor agonists, and the persistently high use of metformin. CONCLUSIONS During the past two decades, combined use of insulin and non-insulin drugs increased and glycemic control improved and leveled off after 2014 in Japanese patients with type 2 diabetes. Further studies of the trend in association with age and factors related to metabolic syndrome are necessary to investigate strategies aiming at personalized medicine in diabetes care.

Abstract
An 11-year-old woman with myelin-oligodendrocyte glycoprotein (MOG) antibody developed cortical encephalitis twice, followed by acute disseminated encephalomyelitis (ADEM) and optic neuritis in one year. Although optic neuritis was refractory after corticosteroid therapy, plasma exchange was effective and complete remission was achieved. We considered that episodes of cortical encephalitis, ADEM and optic neuritis occurred in the present patient can be included in MOG IgG-associated disorders. Also, we recommend plasma exchange for refractory MOG IgG-associated optic neuritis, even in pediatric patient.

Abstract
AIMS/INTRODUCTION Type 2 diabetes mellitus is caused by a relative imbalance between insulin secretion and sensitivity related to the body mass index (BMI). Seven categories of oral antidiabetic drugs (OADs) are available in Japan. It is important to assess the OAD utilization patterns based on patients' BMI levels. MATERIALS AND METHODS OAD prescribing patterns from 2002 to 2019 were analyzed using the data collected in the computerized diabetes care database provided by the Japan Diabetes Clinical Data Management Study Group; OAD utilization patterns in 25,751 OAD-treated type 2 diabetes mellitus patients registered in 2019 were analyzed after classifying them into five categories of BMI. RESULTS Comparing OAD usage between 2002 and 2019, sulfonylureas decreased from 44.5 to 23.2%, and biguanides (BGs) increased from 19.3 to 50.3%. Dipeptidyl peptidase-4 inhibitors (DPP4is) increased to 56.9% in 2019. Sodium-glucose cotransporter 2 inhibitors (SGLT2is) increased to 23.6% in 2019. About 90% of type 2 diabetes mellitus patients had BMI < 30 kg/m2 . DPP4is were the most used OADs in 2019. When BMI exceeded 30 kg/m2 , use of BGs and sodium-glucose cotransporter 2 inhibitors increased, and use of sulfonylureas and DPP4is decreased. Although DPP4is were the most used OADs for patients with BMI <30 kg/m2 , they were the third most prescribed OADs for patients with BMI >35 kg/m2 after BGs and sodium-glucose cotransporter 2 inhibitors . CONCLUSIONS DPP4i usage was as high as that of BG in the analysis of Japanese type 2 diabetes mellitus patients with relatively low BMI. This was considered to be a treatment option appropriate for the pathophysiology in Japanese patients.

Abstract
A 76-year-old man, who received atezolizumab for the treatment for small cell lung cancer, acutely developed limb weakness with sensory disturbance after the third course of the treatment. Nerve conduction studies were consistent with demyelinating polyneuropathy and acute demyelinating polyneuropathy caused by atezolizumab was suggested. Atezolizumab was immediately withdrawn, and intravenous immunoglobulin (IVIg) and methylprednisolone pulse therapies with subsequent oral administration of prednisolone were initiated, after which neurological deficits steadily improved. Although Guillain-Barré syndrome-like neuropathy caused by immune checkpoint inhibitor (ICI) was occasionally reported, this is the first case of acute demyelinating polyneuropathy triggered by atezolizumab, monoclonal antibody targeting programmed death-ligand 1. This case suggests that combined treatments with IVIg and corticosteroids are effective for neuropathy induced by atezolizumab as same as those by other ICI.

Abstract
An 18-year-old man without familial history of neuropathy developed motor and sensory disturbance of bilateral upper limbs after maintaining shoulder abduction/external rotation and elbow flection position of both upper limbs for an hour during military training. Neurological examination and electromyography studies suggested left brachial plexopathy, although a nerve conduction study (NCS) showed mild demyelination of bilateral median nerve and right ulnar nerve. Thoracic outlet syndrome (TOS) was firstly suspected because symptoms were induced by the specific position which narrows, costoclavicular and retropectoralis minor space and cause compression of the brachial plexus; however, no findings suggesting TOS were observed on computed tomography and magnetic resonance imaging. Hence, we suspected a diagnosis of hereditary neuropathy with liability to pressure palsies (HNPP) due to having episodes of bilateral acute brachial plexopathy and mild demyelination on NCS. The diagnosis of HNPP was confirmed by the deletion of the PMP22 gene deletion.

Abstract
An 81-year-old man, who had no history of taking statins, developed progressive muscle weakness of the limbs and dysphagia. Laboratory tests showed a high level of CK and positivity for serum 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibodies. Tests for other autoantibodies to ARS and SRP were negative. A pathological analysis of the left biceps muscle revealed numerous necrotic and regenerated fibers with macrophage infiltration and deposition of C5b-9 complement in and around the myofibers. Chest CT showed a nodular shadow, which was suspected to be lung cancer, in the upper left lobe. A pathological analysis of a transbronchial lung biopsy specimen revealed lung adenocarcinoma with high level of HMGCR. He was diagnosed with HMGCR necrotizing myopathy associated with lung cancer, and both his muscle strength and dysphagia improved after three treatments with intravenous immunoglobulin (IVIg). He did not undergo surgery or radiation therapy because of interstitial pneumonia. This case suggests that a paraneoplastic mechanism caused the production of HMGCR antibodies, leading to myositis in this patient. Treatment with IVIg can be effective for patients with HMGCR antibody-positive paraneoplastic necrotizing myopathy that is refractory to corticosteroid therapy.

Abstract
Cell-surface proteins that can endocytose into brain microvascular endothelial cells serve as promising candidates for receptor-mediated transcytosis across the blood–brain barrier (BBB). Here, we comprehensively screened endocytic cell-surface proteins in hCMEC/D3 cells, a model of human brain microvascular endothelial cells, using surface biotinylation methodology and sequential window acquisition of all theoretical fragment-ion spectra-mass spectrometry (SWATH-MS)-based quantitative proteomics. Using this method, we identified 125 endocytic cell-surface proteins from hCMEC/D3 cells. Of these, 34 cell-surface proteins were selectively internalized into human brain microvascular endothelial cells, but not into human umbilical vein endothelial cells (HUVECs), a model of human peripheral microvascular endothelial cells. Two cell-surface proteins, intercellular adhesion molecule-1 (ICAM1) and podocalyxin (PODXL), were identified as BBB-localized endocytic cell-surface proteins in humans, using open mRNA and protein databases. Immunohistochemical evaluation confirmed PODXL expression in the plasma membrane of hCMEC/D3 cells and revealed that anti-PODXL antibody-labeled cell-surface PODXL internalized into hCMEC/D3 cells. Immunohistochemistry further revealed that PODXL is localized at the luminal side of human brain microvessels, supporting its potential suitability for translational applications. In conclusion, our findings highlight novel endocytic cell-surface proteins capable of internalizing into human brain microvascular endothelial cells. ICAM1 or PODXL targeted antibody or ligand-labeled biopharmaceuticals and nanocarriers may provide effective targeted delivery to the brain across the BBB for the treatment of central nervous system (CNS) diseases.

Abstract
Isolated adrenocorticotropic hormone deficiency (IAD) is a cause of adrenal insufficiency (AI), which shows impaired secretion of adrenocorticotropic hormone (ACTH) with the preserved secretion of other anterior pituitary gland hormones. We herein report a case of IAD complicated by chronic thyroiditis presenting with neuropsychiatric symptoms without other signs indicative of AI that showed complete improvement of the cognitive function after the administration of corticosteroids. The clinical features of our case may be confused with autoimmune encephalopathies (AEs); however, IAD should be strictly differentiated from AEs, as it requires permanent hormone replacement without addition of immunosuppressive agents.

Abstract
OBJECTIVE Dysfunction of the blood-nerve barrier (BNB) plays important roles in chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN). The aim of the present study was to identify the candidate cytokines/chemokines that cause the breakdown of the BNB using sera from patients with CIDP and MMN. METHODS We determined the levels of 27 cytokines and chemokines in human peripheral nerve microvascular endothelial cells (PnMECs) after exposure to sera obtained from patients with CIDP variants (typical CIDP and multifocal acquired demyelinating sensory and motor neuropathy [MADSAM]), MMN and amyotrophic lateral sclerosis (ALS), and healthy controls (HC), using a multiplexed fluorescent bead-based immunoassay system. RESULTS The induced protein (IP)10 level in the cells in both the MADSAM and MMN groups was markedly increased in comparison with the typical CIDP, ALS and HC groups. The other cytokines, including granulocyte colony-stimulating factor,vascular endothelial growth factor (VEGF) and interleukin-7, were also significantly upregulated in the MADSAM group. The increase of IP-10 produced by PnMECs was correlated with the presence of conduction block in both the MADSAM and MMN groups. CONCLUSION The autocrine secretion of IP-10 induced by patient sera in PnMECs was markedly upregulated in both the MADSAM and MMN groups. The overproduction of IP-10 by PnMECs leads to the focal breakdown of the BNB and may help to mediate the transfer of pathogenic T cells across the BNB, thereby resulting in the appearance of conduction block in electrophysiological studies of patients with MADSAM and MMN.

Abstract
Purpose To report a case of macular hole (MH) secondary to a retinal arterial macroaneurysm (RAMA) which was successfully treated with an autologous transplantation of internal limiting membrane (ILM). Case Report An 87-year-old female presented with a sudden decrease in central vision in the right eye. A fundus examination revealed a RAMA in the superonasal macular region, a subretinal hemorrhage (SRH), involving the macula, and a sub-ILM hemorrhage. A pars plana vitrectomy (PPV) was performed. Intraoperatively, an MH filled with coagulum was detected. We tried to blow off and drain the SRH with a current of BSS and a gentle suction with a 27-gauge vitreous cutter from the MH, but some amount of SRH at the bottom of the MH remained. The ILM was peeled off for 2 disc diameters around the MH. The vitreous cavity was filled with air at the end of the operation. Two weeks after the surgery, the MH was not closed. One month following the initial PPV, a second PPV was performed to achieve closure of the MH. Results An autologous transplantation of ILM was performed as second PPV. Six months after the final surgery, the MH was successfully closed and the best-corrected decimal visual acuity was 0.6. Conclusions Autologous ILM transplantation can be an effective treatment option for MH closure following RAMA rupture.

Abstract
Canine pancreatitis is a relatively common disorder, and its mortality rate remains high. However, prognostic factors for pancreatitis based on evidence are
limited. Moreover, the relationship between changes in C-reactive protein (CRP) concentration—an important prognostic factor for human patients with acute
pancreatitis—and the prognosis of dogs with pancreatitis has not been widely studied. Therefore, we examined prognostic factors for canine pancreatitis during
the first medical examination and evaluated the usefulness of serial CRP measurements during hospitalization. Sixty-five dogs met the inclusion criteria,
including 22 that were hospitalized and treated. In Study 1, a multivariate analysis revealed that three factors— decreased platelet count and a marked (greater
than 1,000 µg/l) elevation of specific canine pancreatic lipase (Spec cPL) concentration at the first medical examination, as
well as elevated blood urea nitrogen (BUN) and/or creatinine (CRE) level—were significantly different between the survivors and nonsurvivors. Moreover, CRP
concentrations on the third and fourth days were significantly different between the two groups in Study 2. An evaluation of the decreased platelet count,
remarkable elevation of Spec cPL concentration at the first medical examination, elevation of BUN and/or CRE as well as serial CRP concentration measurements
may be useful for predicting the prognosis of canine pancreatitis.

Abstract
Resveratrol has various attractive bioactivities, such as prevention of cancer, neurodegenerative disorders, and obesity-related diseases. Therefore, identifying its direct binding proteins is expected to discover druggable targets. Sirtuin 1 and phosphodiesterases have so far been found as the direct molecular targets of resveratrol. We herein identified 11 novel resveratrol-binding proteins, including the DEAD (Asp-Glu-Ala-Asp) box helicase 5 (DDX5, also known as p68), using resveratrol-immobilized beads. Treatment with resveratrol induced degradation of DDX5 in prostate cancer cells. Depletion of DDX5 caused apoptosis by inhibiting mammalian target of rapamycin complex 1 (mTORC1) signaling. Moreover, knockdown of DDX5 attenuated the inhibitory activities of resveratrol against mTORC1 signaling and cancer cell growth. These data show that resveratrol directly targets DDX5 and induces cancer cell death by inhibiting the mTORC1 pathway.

Abstract
A 7-year-old neutered male domestic short-haired cat that had undergone contrast radiography of the bowel with barium sulphate after acute episodes of vomiting 2 months previously, was presented with chronic vomiting, anorexia and weight loss. Abdominal radiography and ultrasonography revealed residual contrast enhancement and an obstruction of the small intestine. A contracted and stenosed ileum and distal jejunum were identified by exploratory laparotomy and surgically resected; subsequently, the clinical signs resolved. Histopathological examination of the ileum revealed mucosal ulceration with severe submucosal granulation tissue formation associated with scattered foreign crystalline material. Energy-dispersive X-ray spectroscopy revealed that the crystals contained barium sulphate. This is the first report in animals of the rare complication of barium sulphate incorporation into the gastrointestinal mucosa after contrast radiography.

Abstract
OBJECTIVE The fact that population with type 2 diabetes mellitus and bodyweight of patients are increasing but diabetes care is improving makes it important to explore the up-to-date rates of achieving treatment targets and prevalence of complications. We investigated the prevalence of microvascular/macrovascular complications and rates of achieving treatment targets through a large-scale multicenter-based cohort. RESEARCH DESIGN AND METHODS A cross-sectional nationwide survey was performed on 9956 subjects with type 2 diabetes mellitus who consecutively attended primary care clinics. The prevalence of nephropathy, retinopathy, neuropathy, and macrovascular complications and rates of achieving targets of glycated hemoglobin (HbA1c) <7.0%, blood pressure <130/80 mm Hg, and lipids of low-density/high-density lipoprotein cholesterol <3.1/≥1.0 mmol/L and non-high-density lipoprotein cholesterol <3.8 mmol/L were investigated. RESULTS The rates of achieving targets for HbA1c, blood pressure, and lipids were 52.9%, 46.8% and 65.5%, respectively. The prevalence of microvascular complications was ∼28% each, 6.4% of which had all microvascular complications, while that of macrovascular complications was 12.6%. With an increasing duration of diabetes, the rate of achieving target HbA1c decreased and the prevalence of each complication increased despite increased use of diabetes medication. The prevalence of each complication decreased according to the number achieving the 3 treatment targets and was lower in subjects without macrovascular complications than those with. Adjustments for considerable covariates exhibited that each complication was closely inter-related, and the achievement of each target was significantly associated with being free of each complication. CONCLUSIONS Almost half of the subjects examined did not meet the recommended targets. The risk of each complication was significantly affected by 1 on-target treatment (inversely) and the concomitance of another complication (directly). Total diabetes care including one-by-one management of modifiable risk factors and complications may be important for high-quality care. The future studies including more subjects and clinics with precise complication status are needed.

Abstract
AIMS The protective association of pioglitazone with cardiovascular events and death was investigated over 6-years in large-scale type 2 diabetic subjects without established cardiovascular disease in a primary care setting. METHODS A six-year observational cohort study including 2864 subjects with type 2 diabetes without established cardiovascular disease was performed. The primary endpoint was a composite of first occurrence of cardiovascular disease or death. The effect of pioglitazone use at a baseline year with a Cox proportional hazard model and the time-dependent use in each one-year examination interval with a pooled logistic regression model were analyzed. RESULTS Baseline use of pioglitazone (n=493) did not show a statistically protective effect on the primary endpoint (n=175), although it tended to reduce the risk (adjusted hazard ratio 0.67 [95% CI: 0.43-1.05]). However, pooled logistic regression analysis indicated a significant protective association of pioglitazone with the primary endpoint (0.58 [0.38 to 0.87] and cardiovascular disease (0.54 [0.33-0.88]), independent of concurrent levels of blood glucose, blood pressure, lipids, albuminuria, and renal function. In particular, this protective association was observed in those with diabetic nephropathy regardless of the daily dose of pioglitazone. Among a total of 898 subjects who took pioglitazone during the period, 43% experienced a discontinuation at least once; however, serious adverse effects were rare. CONCLUSIONS This observational study indicated a protective association of pioglitazone with cardiovascular disease and death in type 2 diabetic subjects without established vascular disease, particularly those with nephropathy.

Abstract
OBJECTIVE The cardio-ankle vascular index (CAVI) is an index of arterial stiffness less dependent on blood pressure and an indicator suitable for assessing the arterial dysfunction. However, it remains unclear whether CAVI can predict the outcome of cardiovascular diseases (CVD) in obese patients. METHODS A total of 425 obese Japanese outpatients (189 men and 236 women, mean age: 51.5 years) were enrolled in a multicenter prospective cohort Japan, the Japan Obesity and Metabolic Syndrome Study (JOMS). Primary analysis regarding measurements of cardiovascular risk factors including CAVI and the occurrence of macrovascular complications was based on following the participants over a 5-year period. RESULTS Of the eligible patients, 300 (78%) were followed into the fifth year. During the study period, 15 coronary heart disease, 7 stroke, and 6 arteriosclerosis obliterans events occurred. All events occurred in 28 patients, and CVD incidence rate was 15.8 per 1000 person-years. In the analysis of adjusted models for traditional risk factors, CAVI was a significant factor for the incidence of events. In addition, high CAVI and low HDL-cholesterol were significant factors for the incidence of events in Cox stepwise multivariate analysis when age- and sex-adjusted (CAVI [per 1]: HR = 1.44 [1.02-2.02], p = 0.037; HDL-cholesterol [per 1 mmol/L]: HR = 0.20 [0.06-0.69], p = 0.011). In addition, CAVI added value to atherosclerotic cardiovascular disease risk score in predicting the development of CVD. CONCLUSION This study demonstrates for the first time that CAVI is an effective predictor of CVD events in obese patients.

Abstract
Ollulanus tricuspis is a small nematode parasite of the
stomach, and its infection has been reported worldwide in cats but only one report in dogs
as post-mortem diagnosis. Two dogs, kept in the Tokyo area, were presented for chronic
vomiting. Chronic gastritis was diagnosed histologically, and many nematodes were detected
in endoscopically-biopsied gastric samples and in the mucus of vomitus in both dogs. The
parasites were small (<1 mm), and their morphological characteristics were consistent
with those previously reported for O. tricuspis. The symptoms in one dog
completely disappeared after anthelmintic therapy. To our knowledge, this is the first
report describing ante-mortem diagnosis of spontaneous gastric O.
tricuspis infection in dogs in which infectivity and pathogenicity of the
nematode are suggested.

Abstract
Pancreatic lipase immunoreactivity (Spec fPL) is currently considered to be the most accurate blood test for the diagnosis of feline pancreatitis. In this study, we measured lipase activity in cats using a newer catalytic lipase assay of dry-chemistry system (FDC-v-LIP) to determine the reference range and compared the results with those for Spec fPL. Based on the results of healthy cats, the reference range of FDC-v-LIP was determined to be less than 30 U/l. FDC-v-lip did not show a strong correlation with Spec fPL in cats with various diseases, which resulted in the low sensitivity and positive predictive value. However, the relatively high (>90%) specificity and negative predictive value indicated that FDC-v-LIP could be a useful patient-side screening test for the exclusion of feline pancreatitis.

Abstract
The aim of the present study was to investigate the prevalence of fear of hypoglycemia, in association with severe hypoglycemia and social factors, in insulin-treated patients with type 2 diabetes mellitus. A questionnaire survey on hypoglycemia and patient–physician communication was carried out in 355 patients with insulin-treated type 2 diabetes mellitus patients at 16 hospitals and clinics. A fear of hypoglycemia was reported by 27.7% of patients. A stepwise logistic regression analysis found that severe hypoglycemia during the past 1 year was a significant determinant of fear of hypoglycemia (odds ratio 2.16, 95% confidence interval 1.06–4.41; P = 0.034), and age (odds ratio 1.02, 95% confidence interval 1.00–1.05, P = 0.038) and living alone (odds ratio 1.93, 95% confidence interval 1.00–3.73, P < 0.05) were significantly higher in patients with fear of hypoglycemia than in those without it.

Abstract
The aim of this study is to determine which indicator of chronic kidney disease most closely correlates with 10-year Framingham coronary heart disease (CHD) risk among serum creatinine, serum cystatin C (S-CysC), urine albumin-creatinine ratio (UACR), estimated creatinine-based GFRs (eGFRcre), and estimated CysC-based GFRs (eGFRcys) in patients with obesity and diabetes. Serum creatinine, S-CysC, UACR, and cardio-ankle vascular index (CAVI) were examined in 468 outpatients with obesity and type 2 diabetes, free of severe renal dysfunction or previous history of cardiovascular disease, as a cross-sectional survey using baseline data from the multi-centered Japan Diabetes and Obesity Study. S-CysC and eGFRcys had significantly stronger correlations with the 10-year Framingham CHD risk than serum creatinine, eGFRcre, and UACR (creatinine, ρ = 0.318; S-CysC, ρ = 0.497; UACR, ρ = 0.174; eGFRcre, ρ = -0.291; eGFRcys, ρ = -0.521; P < 0.01 by Fisher's z-test). S-CysC and eGFRcys had significantly stronger correlations with CAVI than serum creatinine, eGFRcre, and UACR (creatinine, ρ = 0.198; S-CysC, ρ = 0.383; UACR, ρ = 0.183; eGFRcre, ρ = -0.302; eGFRcys, ρ = -0.444; P < 0.05 by Fisher's z-test). The receiver operating characteristic curves to distinguish the high-risk patients for CHD revealed significantly larger areas under the curve of S-CysC and eGFRcys than those of serum creatinine, UACR, and eGFRcre (serum creatinine, 0.64; S-CysC, 0.75; UACR, 0.56; eGFRcre, 0.63; eGFRcys, 0.76; P < 0.01). The data suggested that eGFRcys can be more predictive of the 10-year CHD risk than eGFRcre in Japanese patients with obesity and diabetes.

Abstract
The diffraction anomalous fine structure (DAFS) method that is a spectroscopic analysis combined with resonant X-ray diffraction enables the determination of the valence state and local structure of a selected element at a specific crystalline site and/or phase. This method has been improved by using a polycrystalline sample, channel-cut monochromator optics with an undulator synchrotron radiation source, an area detector and direct determination of resonant terms with a logarithmic dispersion relation. This study makes the DAFS method more convenient and saves a large amount of measurement time in comparison with the conventional DAFS method with a single crystal. The improved DAFS method has been applied to some model samples, Ni foil and Fe3O4 powder, to demonstrate the validity of the measurement and the analysis of the present DAFS method.

Abstract
OBJECTIVE Liraglutide (glucagon-like peptide-1 [GLP-1] receptor agonist) and sitagliptin (dipeptidyl peptidase-4 inhibitor) are approved in Japan for treating type 2 diabetes mellitus (T2DM). We compared the efficacy and safety of adding liraglutide or sitagliptin to a sulfonylurea in Japanese T2DM patients. METHODS Patients aged 18 to <80 years with hemoglobin A1c (HbA1c; National Glycohemoglobin Standardization Program [NGSP]) of 6.9–9.4%, body mass index ≤35 kg/m2, and treatment with a sulfonylurea and/or one or two non-sulfonylurea oral antidiabetic drugs for greater than or equal to eight weeks before enrollment were eligible. Patients were randomized in an open-label manner to either 0.9 mg/day liraglutide (n = 50) or 50–100 mg/day sitagliptin (n = 49) and were treated for 24 weeks. Non-sulfonylureas were discontinued before randomization. Patients using other oral antidiabetic drugs started sulfonylurea treatment. The primary endpoint was the change in HbA1c from baseline to Week 24. RESULTS HbA1c decreased in both groups, and the reduction was significantly greater throughout in the liraglutide group except for Week 24 (0.59 ± 0.80 vs. 0.24 ± 0.94%; P = 0.0525). Fasting plasma glucose (FPG) decreased significantly in the liraglutide group compared with the sitagliptin group (−21.15 ± 31.22 vs. +0.46 ± 39.39 mg/dL; P = 0.0014). Homeostasis model assessment of β cell function and C-peptide increased significantly in the liraglutide group but not in the sitagliptin group. Hypoglycemic symptoms and adverse events occurred in four and nine patients, respectively, in the liraglutide group, and in two and five patients, respectively, in the sitagliptin group. CONCLUSION Treatment with liraglutide or sitagliptin together with a sulfonylurea improved HbA1c in Japanese T2DM patients in primary care. Both drugs were associated with low rates of adverse events and hypoglycemia. The improvement in β cell function probably contributed to the improvement in glycemic control in the liraglutide group.

Abstract
BACKGROUND Pathological destruction of blood-brain barrier (BBB) has been thought to be the initial key event in the process of developing multiple sclerosis (MS). The purpose of the present study was to clarify the possible molecular mechanisms responsible for the malfunction of BBB by sera from relapse-remitting MS (RRMS) and secondary progressive MS (SPMS) patients. METHODS We evaluated the effects of sera from the patients in the relapse phase of RRMS (RRMS-R), stable phase of RRMS (RRMS-S) and SPMS on the expression of tight junction proteins and vascular cell adhesion protein-1 (VCAM-1), and on the transendothelial electrical resistance (TEER) in human brain microvascular endothelial cells (BMECs). RESULTS Sera from the RRMS-R or SPMS patients decreased the claudin-5 protein expression and the TEER in BMECs. In RRMS-R, this effect was restored after adding an MMP inhibitor, and the MMP-2/9 secretion by BMECs was significantly increased after the application of patients' sera. In SPMS, the immunoglobulin G (IgG) purified from patients' sera also decreased the claudin-5 protein expression and the TEER in BMECs. The sera and purified IgG from all MS patients increased the VCAM-1 protein expression in BMECs. CONCLUSIONS The up-regulation of autocrine MMP-2/9 by BMECs after exposure to sera from RRMS-R patients or the autoantibodies against BMECs from SPMS patients can compromise the BBB. Both RRMS-S and SPMS sera increased the VCAM-1 expression in the BBB, thus indicating that targeting the VCAM-1 in the BBB could represent a possible therapeutic strategy for even the stable phase of MS and SPMS.

Abstract
Aims/Introduction Six kinds of oral antidiabetic drugs (OADs), including the new dipeptidyl peptidase 4 (DPP‐4) inhibitors, are available. The present study aimed to define trends within the prescribing patterns of OADs, as well as changes in glycemic control in Japan over a 10‐year period from 2002 to 2011. Materials and Methods We carried out a cross‐sectional study using data of type 2 diabetes mellitus patients from 24 clinics for 2002, 2005, 2008 and 2011. OAD use was analyzed combined with clinical data. Results Sulfonylureas (SUs) were the most commonly used OAD, but their use for monotherapy markedly decreased over the study period. Biguanides (BGs) were the second most commonly used OAD, and their prescribing rate increased both for mono‐ and combination therapy. DPP‐4 inhibitors (DPP‐4I), released in 2009, were the third most commonly prescribed OAD in 2011 both for mono‐ and combination therapy. Among combination therapies, two OADs were mostly prescribed, but the use of three OADs and four OADs in 2011 was two‐ and 14.8‐fold those in 2002. These trends were accompanied by an improvement in average glycated hemoglobin from 7.5 ± 1.2% in 2002 to 7.1 ± 0.9% in 2011. Conclusions The OAD prescribing trend has moved away from monotherapy with SUs and toward combination therapies to achieve better glycemic control. Increased use of BGs and DPP‐4I was predominant in 2011. These trends were accompanied by an improvement of the glycated hemoglobin level.

Abstract
We report a 38-year-old man with vaccine associated paralytic poliomyelitis (VAPP) which showed unusual biphasic worsening. The patient developed mild paresis of left upper and right lower extremities, five weeks after the oral poliovirus vaccination of patient's son and two weeks after the intramuscular injection of mumps/varicella vaccine in the left triceps muscle for himself. Needle electromyography (EMG) of his left arm and right leg was not remarkable, and the weakness recovered almost completely in three weeks. However, four weeks after the needle EMG, severe weakness and muscle atrophy of the four extremities, accentuated at the left arm and right leg, developed again. Cervical MRI showed gadolinium-enhanced, T(2) high-signal intensity area in the left C4-C6 anterior horn, most prominent at the height of C5 spine. Significant elevation of serum anti-poliomyelitis type 2 neutralizing antibody confirmed the diagnosis of VAPP. Immunomodulatory treatment, intravenous immunoglobulin (IVIg), did not improve weakness. We consider that the second clinical worsening of this patient was provoked by the needle EMG performed just after the first exacerbation, which injured the skeletal muscles and might have enhanced the retrograde transport of poliovirus via neural pathway.
