Abstract
Background This phase I study aimed to evaluate the safety, peptide-specific immune responses, and anti-tumor effects of a novel vaccination therapy comprising multi-HLA-binding heat shock protein (HSP) 70/glypican-3 (GPC3) peptides and a novel adjuvant combination of hLAG-3Ig and Poly-ICLC against metastatic gastrointestinal cancers. Methods HSP70/GPC3 peptides with high binding affinities for three HLA types (A*24:02, A*02:01, and A*02:06) were identified with our peptide prediction system. The peptides were intradermally administered with combined adjuvants on a weekly basis. This study was a phase I dose escalation clinical trial, which was carried out in a three patients’ cohort; in total, 11 patients were enrolled for the recommended dose. Results Seventeen patients received this vaccination therapy without dose-limiting toxicity. All treatment-related adverse events were of grades 1 to 2. Peptide-specific CTL induction by HSP70 and GPC3 proteins was observed in 11 (64.7%) and 13 (76.5%) cases, respectively, regardless of the HLA type. Serum tumor marker levels were decreased in 10 cases (58.8%). Immunological analysis using PBMCs indicated that patients receiving dose level 3 presented with significantly reduced T cell immunoglobulin and mucin-domain containing-3 (TIM3)-expressing CD4 + T cells after one course of treatment. PD-1 or TIM3-expressing CD4 + T cells and T cell immunoreceptor with immunoglobulin and ITIM domains (TIGIT)-expressing CD8 + T cells in PBMCs before vaccination were negative predictive factors for survival. Conclusions This novel peptide vaccination therapy was safe for patients with metastatic gastrointestinal cancers.

Abstract
Abstract
Background
Stroke and cardiovascular disease are one of the leading causes of death and disability in Japan. In order to investigate current burden, we conduct a population-based registry of cardiovascular disease in Shiga Prefecture, Japan since 2012. We will demonstrate challenges in conduct of the registry study.
Methods
In 2012, we established the Shiga Stroke Registry (SSR), a multicenter population-based registry study designed to build a complete information system for the management of stroke in Shiga Prefecture, Japan. The registry uses local monitoring, combined with remote data collection and quality control systems, to create an integrated surveillance system among a network of all acute care hospitals with neurology/neurosurgery facilities and smaller hospitals with rehabilitation facilities in the region. In 2019, study name has changed to Shiga Stroke and Heart Attack Registry (SSHR) and additional registration of coronary heart disease and aortic disease have started. Each case is reviewed and adjudicated by 2 or more specialists.
Results
In the financial year of 2018 (from April to March), a total of 4809 stroke cases were identified. From December 2018 to April 2019, a total of 515 coronary heart and aortic diseases were identified. A total 10 nurses work full-time for the registry and it takes average of 1 hour to collect information for each patient. Challenges in conduct of the cardiovascular registry involve regulatory and ethical approval, funding, associations with local hospitals, non-standardized hospital diagnosis, staff training for comprehensive data collection including pathophysiology, examination and treatment, and quality control of data collection.
Conclusions
SSHR is a population-based registry of wide range of stroke and cardiovascular disease in Shiga Prefecture, Japan. In order to keep quality of the data, we put a lot of efforts on staff training and quality control.

Abstract
BACKGROUND AND PURPOSE The association between an increased supraventricular ectopic beat (SVEB) and subclinical cerebrovascular disease remains unclear. Given the emerging concept that an increased SVEB is a marker of atrial cardiomyopathy or atherosclerosis burden, we sought to determine whether excessive supraventricular ectopic activity (ESVEA) is associated with a higher burden of subclinical cerebrovascular disease in the middle-aged to older cohort with neither apparent stroke nor atrial fibrillation. METHODS We conducted a cross-sectional population-based study of 462 men (mean age, 68.1 years) who underwent 24-h Holter electrocardiography and brain magnetic resonance imaging. ESVEA was defined as the presence of >10 SVEBs/h. Subclinical cerebrovascular diseases were defined as silent brain infarct (SBI), white matter hyperintensity (WMH) and intracranial atherosclerotic stenosis (ICAS). The association of ESVEA with the presence of subclinical cerebrovascular diseases was adjusted for potential confounding covariates. RESULTS A total of 88 (19.0%) participants had ESVEA and 81 (17.5%), 91 (19.7%) and 109 (23.6%) had SBI, WMH and ICAS, respectively. In multivariable-adjusted Poisson regression with robust error variance, ESVEA was associated with the presence of WMH (relative risk, 1.58; 95% confidence interval, 1.06-2.36) and ICAS (relative risk, 1.49; 95% confidence interval, 1.02-2.18), but not with that of SBI (relative risk, 1.32; 95% confidence interval, 0.86-2.01). These associations were consistent when the graded distributions of subclinical cerebrovascular diseases were applied as outcomes in ordinal logistic regression. CONCLUSIONS The ESVEA was independently associated with higher burdens of WMH and ICAS. This suggests that increased SVEBs might improve risk stratification of individuals at high risk of subclinical cerebrovascular disease and consequently apparent ischaemic stroke.

Abstract
Background Thus far, studies on Klebsiella pneumoniae carbapenemase (KPC)-producing organisms have only been reported in those with a history of foreign travel, and a specific Japanese KPC-producing isolate has not yet been reported. Case presentation We describe a Japanese patient, with no history of travel to foreign countries, admitted due to aspiration pneumonia, and a KPC-producing isolate detected in his sputum. Fortunately, his pneumonia resolved. His close contacts did not have a history of foreign travel, and the isolate was not detected in other patients. Conclusions The potential for KPC-producing organisms to become endemic in Japan is currently of great concern.

Abstract
BACKGROUND Work-related psychosocial factors have been associated with metabolic syndrome. However, no systematic reviews or meta-analyses have evaluated this association. METHODS A systematic literature search was conducted, using PubMed, Embase, PsycINFO, PsycARTICLES and the Japan Medical Abstracts Society. Eligible studies included those that examined the previously mentioned association; had a longitudinal or prospective cohort design; were conducted among workers; provided sufficient data for calculating odds ratios, relative risks or hazard ratios with 95% confidence intervals; were original articles in English or Japanese; and were published no later than 2016. Study characteristics, exposure and outcome variables and association measures of studies were extracted by the investigators independently. RESULTS Among 4,664 identified studies, 8 were eligible for review and meta-analysis. The pooled risk of adverse work-related stress on metabolic syndrome onset was significant and positive (RR = 1.47; 95% CI, 1.22-1.78). Sensitivity analyses limiting only the effects of job strain and shift work also indicated a significant positive relationship (RR = 1.75; 95% CI, 1.09-2.79; and RR = 1.59; 95% CI, 1.00-2.54, P = 0.049 respectively). CONCLUSION This study reveals a strong positive association between work-related psychosocial factors and an elevated risk of metabolic syndrome onset. The effects of job strain and shift work on metabolic syndrome appear to be significant.

Sex-specific relevance of diabetes to occlusive vascular and other mortality: a collaborative meta-analysis of individual data from 980 793 adults from 68 prospective studies. Lancet Diabetes Endocrinol 2018; 6:538-546. [PMID: 29752194 PMCID: PMC6008496 DOI: 10.1016/s2213-8587(18)30079-2] [Citation(s) in RCA: 129] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 02/20/2018] [Accepted: 02/26/2018] [Indexed: 01/06/2023]
Abstract
BACKGROUND Several studies have shown that diabetes confers a higher relative risk of vascular mortality among women than among men, but whether this increased relative risk in women exists across age groups and within defined levels of other risk factors is uncertain. We aimed to determine whether differences in established risk factors, such as blood pressure, BMI, smoking, and cholesterol, explain the higher relative risks of vascular mortality among women than among men. METHODS In our meta-analysis, we obtained individual participant-level data from studies included in the Prospective Studies Collaboration and the Asia Pacific Cohort Studies Collaboration that had obtained baseline information on age, sex, diabetes, total cholesterol, blood pressure, tobacco use, height, and weight. Data on causes of death were obtained from medical death certificates. We used Cox regression models to assess the relevance of diabetes (any type) to occlusive vascular mortality (ischaemic heart disease, ischaemic stroke, or other atherosclerotic deaths) by age, sex, and other major vascular risk factors, and to assess whether the associations of blood pressure, total cholesterol, and body-mass index (BMI) to occlusive vascular mortality are modified by diabetes. RESULTS Individual participant-level data were analysed from 980 793 adults. During 9·8 million person-years of follow-up, among participants aged between 35 and 89 years, 19 686 (25·6%) of 76 965 deaths were attributed to occlusive vascular disease. After controlling for major vascular risk factors, diabetes roughly doubled occlusive vascular mortality risk among men (death rate ratio [RR] 2·10, 95% CI 1·97-2·24) and tripled risk among women (3·00, 2·71-3·33; χ2 test for heterogeneity p<0·0001). For both sexes combined, the occlusive vascular death RRs were higher in younger individuals (aged 35-59 years: 2·60, 2·30-2·94) than in older individuals (aged 70-89 years: 2·01, 1·85-2·19; p=0·0001 for trend across age groups), and, across age groups, the death RRs were higher among women than among men. Therefore, women aged 35-59 years had the highest death RR across all age and sex groups (5·55, 4·15-7·44). However, since underlying confounder-adjusted occlusive vascular mortality rates at any age were higher in men than in women, the adjusted absolute excess occlusive vascular mortality associated with diabetes was similar for men and women. At ages 35-59 years, the excess absolute risk was 0·05% (95% CI 0·03-0·07) per year in women compared with 0·08% (0·05-0·10) per year in men; the corresponding excess at ages 70-89 years was 1·08% (0·84-1·32) per year in women and 0·91% (0·77-1·05) per year in men. Total cholesterol, blood pressure, and BMI each showed continuous log-linear associations with occlusive vascular mortality that were similar among individuals with and without diabetes across both sexes. INTERPRETATION Independent of other major vascular risk factors, diabetes substantially increased vascular risk in both men and women. Lifestyle changes to reduce smoking and obesity and use of cost-effective drugs that target major vascular risks (eg, statins and antihypertensive drugs) are important in both men and women with diabetes, but might not reduce the relative excess risk of occlusive vascular disease in women with diabetes, which remains unexplained.

Abstract
3086 Background: Based on the exploratory analysis of our previous studies of peptide vaccine, we concluded that the combination of adjuvants hLAG-3Ig + Poly-ICLC is essential for controlling negative immune checkpoints and enhancing the induction of CTLs to overcome the traditional peptide studies. Another issue with peptide vaccines is human leukocyte antigen (HLA) restriction. Hence, we developed novel multi-HLA-binding peptides derived from the tumor antigens, HSP70 and GPC3, and confirmed the high expression in many types of cancer. Methods: For the identification of peptides, HSP70- and GPC3-derived peptides that have high binding affinity to each of HLA-A2402, 0201, and 0206 were selected as candidate peptides by a binding prediction system (NEC Corporation). We then identified priority candidate peptides by using a peptide-binding assay. Using peripheral mononuclear blood cells from cancer patients, CD8+ T lymphocytes were stimulated with the candidate peptides, and an enzyme-linked immunospot assay was performed. Finally, we identified HSP70- and GPC3-peptide. In this phase I study of a novel peptide cancer vaccine for metastatic solid cancer, primary objective was to evaluate its safety and toxicity. Secondary objective was to examine the immune and clinical response, and also to determine the recommendable dose. This study used a three-tiered dose-escalation strategy with 3 patients’ cohorts. In addition to the 3 scheduled cases, 3 more cases were added and 6 cases were enrolled at the recommended dose. Results: Twelve HLA-A*24:02-, 02:01-, and 02:06-matched patients (esophagus, 3; colon, 4; liver, 3; pancreas, 1; stomach, 1) were treated in this study. No severe adverse effects related to the treatment were encountered. Peptide-specific CTL induction with HSP70 and GPC3 was observed in 10 and 11 patients, respectively. We observed decreased tumor marker expression in 6 cases, and disease control was observed in f5 patients (4, 3, 8, 2, 2 months, respectively). Conclusions: The combination cancer vaccine therapy using multi-HLA-restricted peptides and hLAG-3Ig + Poly-ICLC was safe and effective for treating solid tumors; it therefore warrants further clinical studies.

Predictive biomarkers for the efficacy of peptide vaccine treatment: based on the results of a phase II study on advanced pancreatic cancer. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2017; 36:36.

Abstract
Background The purpose of the present study was to explore novel biomarkers that can predict the clinical outcome of patients before treatment or during vaccination. These would be useful for the selection of appropriate patients who would be expected to exhibit better treatment outcomes from vaccination, and for facilitating the development of cancer vaccine treatments. Methods From a single-arm, non-randomized, human leukocyte antigen (HLA)-A-status-blind phase II trial of a vaccine treatment using three HLA-A*2402-restricted peptides for advanced pancreatic cancer (PC), we obtained peripheral blood samples from 36 patients of an HLA-A*2402-matched group and 27 patients of an HLA-A*2402-unmatched group. Results Multivariate analysis (HR = 2.546; 95% CI = 1.138 to 5.765; p = 0.0231) and log-rank test (p = 0.0036) showed that a high expression level of programmed death-1 (PD-1) on CD4+ T cells was a negative predictive biomarker of overall survival in the HLA-A*2402-matched group . Moreover, a high expression level of PD-1 on CD4+ T cells was a negative predictor for the induction of cytotoxic T lymphocytes (p = 0.0007). After treatment, we found that the upregulation of PD-1 and T cell immunoglobulin mucin-3 (Tim-3) expression on CD4+ and CD8+ T cells was significantly associated with a poor clinical outcome in the HLA-A*2402-matched group (p = 0.0330, 0.0282, 0.0046, and 0.0068, respectively). In contrast, there was no significant difference for these factors in the HLA-A*2402-unmatched group. Conclusions Our results indicate that the upregulation of PD-1 and Tim-3 expression on CD4+ and CD8+ T cells may restrict T cell responses in advanced PC patients; therefore, combination immunotherapy with blockade of PD-1 and Tim-3 to restore T cell responses may be a potential therapeutic approach for advanced PC patients.

Abstract
We previously conducted a phase I clinical trial combining the HLA-A*2402-restricted KIF20A-derived peptide vaccine with gemcitabine for advanced pancreatic cancer (PC) and confirmed its safety and immunogenicity in cancer patients. In this study, we conducted a multicenter, single-armed, phase II trial using two antiangiogenic cancer vaccines targeting VEGFR1 and VEGFR2 in addition to the KIF20A peptide. We attempted to evaluate the clinical benefit of the cancer vaccination in combination with gemcitabine. Chemotherapy naïve PC patients were enrolled to evaluate primarily the 1-year survival rate, and secondarily overall survival (OS), progression free survival (PFS), response rate (RR), disease control rate (DCR) and the peptide-specific immune responses. All enrolled patients received therapy without the HLA-A information, and the HLA genotypes were used for classification of the patients. Between June 2012 and May 2013, a total of 68 patients were enrolled. No severe systemic adverse effects of Grade 3 or higher related to these three peptides were observed. The 1-year survival rates between the HLA-A*2402-matched and -unmatched groups were not significantly different. In the HLA-A*2402 matched group, patients showing peptide-specific CTL induction for KIF20A or VEGFR1 showed a better prognosis compared to those without such induction (P = 0.023, P = 0.009, respectively). In the HLA-A*2402-matched group, the patients who showed a strong injection site reaction had a better survival rate (P = 0.017) compared to those with a weak or no injection site reaction. This phase II study demonstrated that this therapeutic peptide cocktail might be effective in patients who demonstrate peptide-specific immune reactions although predictive biomarkers are needed for patient selection in its further clinical application.

Abstract
OBJECTIVES Depression and anxiety after stroke occur frequently and have been suggested to have negative influence on functional outcomes. However, the effect of emotional symptoms on stroke recurrence is uncertain. The aim of this study was to define the effect of emotional symptoms on recurrent cerebrovascular events in patients with ischemic stroke. MATERIALS AND METHODS This was a hospital-based cohort study including patients with ischemic stroke who participated in a Community Stroke Care Program that provided secondary stroke prevention strategies during 6 months transition period after discharge. We examined the association between depression and anxiety and the risk of recurrent cerebrovascular events using logistic regression model. Depression and anxiety were defined as a score of 7 or more in Hospital Anxiety and Depression Scale at 2 weeks after discharge. Recurrent cerebrovascular events comprised any recurrent stroke and transient ischemic attack (TIA) occurring during 6 months after discharge. RESULTS Among 182 patients, 29 (15.9%) were depressed and 41 (22.5%) had anxiety symptoms. During the follow-up period, 9 patients experienced recurrent cerebrovascular events (5 of stroke and 4 of TIA). Depression was associated with recurrent cerebrovascular events at 6 months after adjustment for age, sex, and stroke severity (OR 5.22, 95% CI 1.08-25.12; P = 0.04), whereas anxiety was not (OR 0.98, 95% CI 0.2-4.92; P = 0.982). CONCLUSIONS Depression occurring early after stroke was associated with the increased risk of recurrent cerebrovascular events in ischemic stroke survivors. Care plan to detect and manage depression should be implemented to prevent recurrent stroke.

METHODS A subsidiary analysis of the INTERACT Pilot and INTERACT2 studies--randomised controlled trials of patients with spontaneous acute ICH with elevated systolic blood pressure (BP), randomly assigned to intensive (target systolic BP <140 mm Hg) or guideline-based (<180 mm Hg) BP management. Outcomes were the combined and separate end points of death and major disability (modified Rankin scale (mRS) scores of 3-6, 6 and 3-5, respectively) at 90 days. RESULTS A total of 2708 patients had supratentorial/hemispheric ICH and information on mRS at 90 days. Patients with right hemispheric ICH (1327, 49%) had a higher risk of death at 90 days compared to those with left hemispheric ICH after adjustment for potential confounding variables (OR, 1.77 (95% CI 1.33 to 2.37)). There were no differences between patients with right and left hemispheric ICH regarding the combined end point of death or major disability or major disability in the multivariable-adjusted models (1.07 (0.89 to 1.29) and 0.85 (0.72 to 1.01), respectively). CONCLUSIONS Right hemispheric lesion was associated with increased risk of death in patients with acute ICH. The laterality of the ICH does not appear to affect the level of disability in survivors.

Abstract
BACKGROUND The cardiovascular benefits of blood pressure lowering in obese people compared with people of normal weight might depend on choice of drug. We compared the effects of blood pressure-lowering regimens on cardiovascular risk in groups of patients categorised by baseline body-mass index (BMI). METHODS We used individual patient data from trials included in the Blood Pressure Lowering Treatment Trialists' Collaboration to compare the effects of different classes of blood pressure-lowering regimens for the primary outcome of total major cardiovascular events (stroke, coronary heart disease, heart failure, and cardiovascular death). We used meta-analyses and meta-regressions to assess interactions between treatment and BMI when fitted as either a categorical variable (<25 kg/m(2), 25 to <30 kg/m(2), and ≥30 kg/m(2)) or a continuous variable. FINDINGS Analyses were based on 135,715 individuals from 22 trials who had 14,353 major cardiovascular events. None of the six primary comparisons showed evidence that protection varied by drug class across the three BMI groups (all p for trend >0·20). When analysed as a continuous variable, angiotensin-converting-enzyme inhibitors gave slightly greater protection for each 5 kg/m(2) higher BMI than did calcium antagonists (hazard ratio 0·93, 95% CI 0·89-0·98; p=0·004) or diuretics (0·93, 0·89-0·98; p=0·002). The meta-regressions showed no relation between BMI category and the risk reduction for a given fall in systolic blood pressure. By contrast with a previous report, we noted no relation between BMI and the efficacy of calcium antagonists compared with diuretics. INTERPRETATION We found little evidence that selection of a particular class of blood pressure-lowering drug will lead to substantially different outcomes for individuals who are obese compared with those who are lean. FUNDING None.

Abstract
We developed a six-axis multi-anvil press, ATSUHIME, for high-pressure and high-temperature in situ time-of-flight neutron powder diffraction experiments. The press has six orthogonally oriented hydraulic rams that operate individually to compress a cubic sample assembly. Experiments indicate that the press can generate pressures up to 9.3 GPa and temperatures up to 2000 K using a 6-6-type cell assembly, with available sample volume of about 50 mm(3). Using a 6-8-type cell assembly, the available conditions expand to 16 GPa and 1273 K. Because the six-axis press has no guide blocks, there is sufficient space around the sample to use the aperture for diffraction and place an incident slit, radial collimators, and a neutron imaging camera close to the sample. Combination of the six-axis press and the collimation devices realized high-quality diffraction pattern with no contamination from the heater or the sample container surrounding the sample. This press constitutes a new tool for using neutron diffraction to study the structures of crystals and liquids under high pressures and temperatures.

Abstract
Background:
Acute blood pressure (BP) lowering therapy has shown clinical benefit in patients with acute intracerebral hemorrhage (ICH), but the effect of timing and degree of BP control on ICH growth has received less study.
Methods:
Among the INTERACT2 participants (N=2839) with acute ICH allocated either to intensive BP lowering therapy (IT, systolic target <140mmHg) or standard BP treatment (ST), CT brain imaging at baseline and 24 hours were centrally analysed in a subset of 491 (34%) in the IT and 473 (34%) in the ST groups.
Results:
Absolute mean ICH growth was lower in patients reaching BP target in <1h from randomization (1.7ml), as compared to those reaching target in 1-6h (4.2ml), and >6h (4.6ml, p=0.04). Hematoma growth was particularly high (14.4ml, 95%CI:10.0-18.8) in patients admitted with systolic BP>160mmHg who achieved <10mmHg systolic BP lowering over 24h, as compared to those achieving 10-20mmHg (3.7ml, 95%CI:0.3-7.1) or 20-30mmHg BP reduction (2.7ml, 95%CI:1.1-4.3); p<0.01). Patients maintaining target BP at 0-2 measurements over 24h had higher absolute volume increase (3.6ml; 95%CI:1.8-5.4) as compared to those who maintained target BP over 3-4 (1.6ml, 95%CI:-0.3-3.5), or 5-8 measurements (0.4ml, 95%CI:-1.7-2.4; p=0.01).
Conclusion:
These findings suggest that early and sustained BP control have favorable effects on hematoma growth. This reinforces the principle for patients with acute ICH to receive BP lowering therapy as early as possible and to achieve a lower level of systolic BP for the most favorable outcome.

Abstract
BACKGROUND AND PURPOSE As uncertainty persists over the prognostic significance of low estimated glomerular filtration rate (eGFR) in acute stroke, the effects of low eGFR on death/disability amongst participants with acute stroke in China were determined. METHODS Nanjing First Hospital stroke registry was a prospective cohort study of stroke patients. Patients with acute stroke (brain infarction, intracerebral hemorrhage or subarachnoid hemorrhage) within 7 days of onset were recruited consecutively from 2004 to 2008. Baseline eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equation. Outcomes were death/disability, defined by scores 3-6 on the modified Rankin Scale at 90 days. RESULTS A total of 1909 participants were included in the present analyses. Of them, 112 (5.9%) had baseline moderate to severe decrease in eGFR (G3b-4) and increasing risk of higher National Institutes of Health Stroke Scale (NIHSS) scores. Low eGFR was associated with increasing risk of death/disability at 90 days [G3b-4, odds ratio 2.58 (95% confidence interval 1.71-3.91); G3a, 1.86 (1.35-2.56); G2, 1.21 (0.96-1.52); P trend <0.001). However, the association was not statistically significant after adjustment for demographic and clinical factors including NIHSS scores. CONCLUSIONS There were no appreciable effects of low eGFR on death/disability at 90 days independent of other prognostic factors in Chinese patients with acute stroke.

Abstract
BACKGROUND It has not been fully elucidated whether antihypertensive medication adherence affects blood pressure (BP) control in hypertension cases. AIM To investigate the association of adherence to antihypertensive drug regimens and BP control using data from the Combination Pill of Losartan Potassium and Hydrochlorothiazide for Improvement of Medication Compliance Trial (COMFORT) study. DESIGN An observational analysis from a randomized controlled trial. METHODS A total of 203 hypertensive subjects were randomly assigned to a daily regimen of a combination pill (losartan 50 mg/hydrochlorothiazide 12.5 mg) or two pills, an angiotensin II receptor blocker and a thiazide diuretic. Medication adherence calculated based on pill counts and BPs was evaluated at 1, 3 and 6 months after randomization. RESULTS The subjects were divided into three groups according to their adherence, i.e. relatively low-adherence (<90%; n = 19), moderate-adherence (90-99%; n = 71) and high-adherence (100%; n = 113) groups. Clinical characteristics of the subjects including BP, sex, randomized treatments and past medical history did not differ significantly among the three groups. Achieved follow-up BPs over the 6-month treatment period, which were adjusted for age, sex, baseline BP and randomized treatment, were significantly higher in the low-adherence group (135/78 mmHg) compared with the high-adherence (130/74 mmHg; P = 0.02/0.02) and the moderate-adherence (128/74 mmHg; P = 0.003/0.02) groups. CONCLUSION Low adherence to an antihypertensive-drug regimen was associated with poor BP control.

Abstract
Previous x-ray diffraction measurements revealed the pressure-induced decomposition of an fcc LaH2.3 into H-rich and H-poor fcc phases around 11 GPa. The present neutron diffraction measurements on LaD2 confirm the formation of NaCl-type LaD as a counterpart of the D-rich LaD2+δ by disproportionation. First-principles enthalpy and lattice dynamic calculations demonstrate that the NaCl-type LaH is stabilized at high pressures and can be recovered at ambient conditions. Finding the NaCl-type LaH will pave the way for investigations on the site-dependent nature of hydrogen-metal interactions.

Abstract
BACKGROUND Angiopoietin-like protein 4 (Angptl4) is thought to cause an increase in serum triglyceride levels. In the present study, we elucidated Angptl4 expression in the mouse models of type 1 and type 2 diabetes mellitus, and investigated the possible mechanisms involved. METHODS Type 1 diabetes was induced in C57BL/6 J mice by treating them with streptozotocin (STZ). Type 2 diabetes was induced by feeding the mice a high-fat diet (HFD) for 18 weeks. RESULTS The levels of Angptl4 mRNA expression in liver, white adipose tissue (WAT), and brown adipose tissue (BAT) were found to increase in the STZ diabetic mice relative to control mice. This effect was attenuated by insulin administration. In the HFD diabetic mice, the Angptl4 mRNA expression levels were increased in liver, WAT, and BAT. Treatment with metformin for 4 weeks attenuated the increased levels of Angptl4 mRNA. Fatty acids (FAs) such as palmitate and linoleate induced Angptl4 mRNA expression in H4IIE hepatoma cells and 3T3-L1 adipocytes. Treatment with insulin but not metformin attenuated FA-induced Angptl4 mRNA expression in H4IIE. Both insulin and metformin did not influence the effect of FAs in 3T3-L1 cells. CONCLUSION These observations demonstrated that Angptl4 mRNA expression was increased through the elevated free FAs in diabetic mice.

Abstract
OBJECTIVE To examine secular trends in the prevalence of Alzheimer's disease (AD) and vascular dementia (VD) in a general Japanese population. METHOD Four cross-sectional examinations were conducted among residents of a Japanese community aged >or=65 in 1985, 1992, 1998 and 2005. RESULTS The age- and sex-adjusted prevalence of all-cause dementia significantly increased with time (6.0% in 1985, 4.4% in 1992, 5.3% in 1998 and 8.3% in 2005; P for trend = 0.002). A similar trend was observed for AD (1.1%, 1.3%, 2.3% and 3.8% respectively; P for trend < 0.001), while the age- and sex-adjusted prevalence of VD and other/unclassified dementia showed J-shaped patterns (for VD: 2.3%, 1.5%, 1.5% and 2.5%, respectively, P for trend = 0.82; for other/unclassified dementia: 2.6%, 1.7%, 1.5% and 2.0%, P for trend = 0.26). The prevalence of AD was likely to increase with time from 1985 to 2005 among subjects aged 75 or older. The ratio of the prevalence of VD to that of AD decreased with time (2.1 in 1985, 1.2 in 1992, 0.7 in 1998 and 0.7 in 2005). CONCLUSION Our findings suggest that the prevalence of all-cause dementia and AD significantly increased over the past two decades in the general Japanese population.

Abstract
Familial neurohypophysial diabetes insipidus (FNDI), an autosomal dominant disorder, is mostly caused by mutations in the gene of neurophysin II (NPII), the carrier protein of arginine vasopressin (AVP). The analyses of knock-in mice expressing a mutant NPII that causes FNDI in humans demonstrated that polyuria progressed substantially in the absence of loss of AVP neurones. Morphological analyses revealed that inclusion bodies were present in the AVP neurones in the supraoptic nucleus and that the size and numbers of inclusion bodies gradually increased in parallel with the increases in urine volume. Electron microscopic analyses showed that aggregates existed in the endoplasmic reticulum (ER) of AVP neurones. These data suggest that cell death is not the primary cause of polyuria in FNDI, and that the aggregate formation in the ER is likely to be related to the pathogenesis of the progressive polyuria.

Abstract
BACKGROUND Hedgehog (Hh) signaling plays an important role in pancreas development. However, its role in the developed endocrine pancreas remains to be elucidated. To clarify whether Hh signaling participates in beta-cell survival, we investigated the role of Hh signaling in cytokine-induced apoptosis in pancreatic beta-cells. METHODS Insulin-producing INS-1E cells were transfected with Sonic Hh (Shh) expression vector or siRNA against Indian Hh (siIhh). The Hh signal inhibitor cyclopamine were pretreated in INS-1E cells and rat islets. The cells were exposed to 200 U/ml IL-1β and 200 U/ml IFN-γ for 48 h. Apoptosis was estimated by flow cytometory and immunofluorescence staining for cleaved caspase-3. Nitric oxide generation was measured by Griess reaction. RESULTS We found that exposure to proinflammatory cytokines increased Ihh expression in rat islets and INS-1E cells. Overexpression of Shh reduced cytokine-induced apoptosis. By contrast, treatment with cyclopamine increased cytokine-induced apoptosis in INS-1E cells and rat islets. Treatment with the siIhh showed same results in INS-1E cells. Forced expression of Shh suppressed cytokine-induced nuclear factor-κB promoter activity, leading to attenuation of nitric oxide synthase 2 expression and nitric oxide production, while Ihh knockdown enhanced this pathway in INS-1E cells. CONCLUSION Our findings suggest that Hh signaling is implicated in protecting beta-cells from cytokine-induced cytotoxicity.

Abstract
Rationale: The INTERACT pilot study demonstrated the feasibility of the protocol, safety of early intensive blood pressure lowering and effects on haematoma expansion within 6h of onset of intracerebral haemorrhage. This article describes the design of the second, main phase, INTERACT2. Aims: To compare the effects of a management strategy of early intensive blood pressure lowering with a more conservative guideline-based blood pressure management policy in patients with acute intracerebral hemorrhage. Design: INTERACT2 is a prospective, randomized, open label, assessor-blinded end-point (PROBE). Patients with a systolic blood pressure greater than 150 mmHg and no definite indication for or contraindication to blood pressure-lowering treatment are centrally randomised to either of two treatment groups within 6h onset of intracerebral haemorrhage. Those allocated to intensive blood pressure lowering will receive primarily intravenous, hypotensive agents to achieve a systolic blood pressure target of <140 mmHg within 1 h of randomisation and to maintain this level for up to 7 days in hospital. The control group will receive blood pressure-lowering treatment to a target systolic blood pressure of < 180 mmHg. Both groups are to receive similar acute stroke unit care, therapy and active management. Oral antihypertensive therapy is recommended in patients before hospital discharge with a long-term systolic blood pressure goal of 140 mmHg according to secondary stroke prevention guidelines. A projected 2800 subjects are to be enrolled from approximately 140 centres worldwide to provide 90% power (α 0·05) to detect a 14% difference in the risk of death and dependency between the groups, which equates to one or more cases of a poor outcome prevented in every 15 patients treated. Study outcomes: The primary outcome is the combined end-point of death and dependency according to the modified Rankin Scale at 90 days. The secondary outcomes are the separate components of the primary end-point in patients treated <4 hours of ICH onset, grades of physical function on the modified Rankin Scale, health-related quality of life on the EuroQoL, recurrent stroke and other vascular events, days of hospitalisation, requirement for permanent residential care and unexpected serious adverse events. The study is registered under NCT00716079, ISRCTN73916115 and ACTRN12608000362392.

Abstract
A compact cubic-anvil high-pressure device was developed for in situ neutron powder diffraction studies. In this device, a cubic shaped pressure medium is compressed by six anvils, and neutron beams pass through gaps between the anvils. The first high-pressure experiment using this device was conducted at J-PARC and clearly showed the neutron diffraction patterns of Pb. Combining the cubic-anvil high-pressure device with a pulsed neutron source will prove to be a useful tool for neutron diffraction experiments.

Abstract
BACKGROUND Uncertainty surrounds the effects of cerebral edema on outcomes in intracerebral hemorrhage (ICH). METHODS We used data from the INTERACT trial to determine the predictors and prognostic significance of "perihematomal" edema over 72 hours after ICH. INTERACT included 404 patients with CT-confirmed ICH and elevated systolic blood pressure (BP) (150-220 mm Hg) who had the capacity to commence BP lowering treatment within 6 hours of ICH. Baseline and repeat CT (24 and 72 hours) were performed using standardized techniques, with digital images analyzed centrally. Predictors of growth in edema were determined using generalized estimating equations, and its effects on clinical outcomes were estimated using a logistic regression model. RESULTS Overall, 270 patients had 3 sequential CT scans available for analyses. At baseline, there was a highly significant correlation between hematoma and perihematomal edema volumes (r(2) = 0.45). Lower systolic BP and baseline hematoma volume were independently associated with absolute increase in perihematomal edema volume. History of hypertension, baseline hematoma volume, and earlier time from onset to CT were independently associated with relative increase in edema volume. Both absolute and relative increases in perihematomal edema growth were significantly associated with death or dependency at 90 days after adjustment for age, gender, and randomized treatment, but not when additionally adjusted for baseline hematoma volume. CONCLUSIONS The degree of, and growth in, perihematomal edema are strongly related to the size of the underlying hematoma of acute intracerebral hemorrhage, and do not appear to have a major independent effect in determining the outcome from this condition.

Abstract
OBJECTIVE To estimate the incidence and survival rates of total and cause specific dementia in a general Japanese population. METHODS A total of 828 subjects without dementia, aged 65 years or over, were followed-up prospectively for 17 years. Dementia was subdivided into cause specific subtypes: namely, Alzheimer's disease (AD), vascular dementia (VD), dementia with Lewy bodies (DLB), combined dementia and other types of dementia. During the follow-up, 275 subjects developed dementia; of these, 251 (91.2%) were evaluated morphologically, with 164 subjected to brain autopsy examination and the remaining 87 to neuroimaging. RESULTS The incidences of total dementia, AD, VD, DLB, combined dementia and other types of dementia were 32.3 (n = 275), 14.6 (124), 9.5 (81), 1.4 (12), 3.8 (33), and 3.1 (16) per 1000 person years, respectively. The incidences of AD, combined dementia and other types of dementia rose with increasing age, particularly after the age of 85 years, but this tendency was not observed for VD or DLB. The survival curve of dementia cases aged 65-89 years was significantly lower than that of age and sex matched controls (10 year survival rate, 13.6% vs 29.3%; hazard ratio 1.67; 95% confidence interval 1.31 to 2.13). The 10 year survival rates were not significantly different among dementia subtypes. CONCLUSIONS Our findings suggest that the Japanese elderly population has a high risk for the development of dementia, specifically AD and VD, and once dementia is established, the risk of death is considerable.

Abstract
OBJECTIVE To quantify the relative risk reductions achieved with different regimens to lower blood pressure in younger and older adults. DESIGN Meta-analyses and meta-regression analyses used to compare the effects on the primary outcome between two age groups (<65 v > or =65 years). Evidence for an interaction between age and the effects of treatment sought by fitting age as a continuous variable and estimating overall effects across trials. PRIMARY OUTCOME total major cardiovascular events. RESULTS 31 trials, with 190 606 participants, were included. The meta-analyses showed no clear difference between age groups in the effects of lowering blood pressure or any difference between the effects of the drug classes on major cardiovascular events (all P> or =0.24). Neither was there any significant interaction between age and treatment when age was fitted as a continuous variable (all P>0.09). The meta-regressions also showed no difference in effects between the two age groups for the outcome of major cardiovascular events (<65 v > or =65; P=0.38). CONCLUSIONS Reduction of blood pressure produces benefits in younger (<65 years) and older (> or =65 years) adults, with no strong evidence that protection against major vascular events afforded by different drug classes varies substantially with age.
