■ Paper- Schizophrenia is a common chronic psychiatric disorder that causes age-related dysfunction. The life expectancy in patients with schizophrenia is ≥10 years shorter than that in the general population because of the higher risk of other diseases, such as cardiovascular diseases. Aging studies based on DNA methylation status have received considerable attention. Several epigenetic age accelerations and predicted values of aging-related proteins (GrimAge and GrimAge2 components) have been analyzed in multiple diseases. However, no studies have investigated up to GrimAge and GrimAge2 components between patients with schizophrenia and controls. Therefore, we aimed to conduct multiple regression analyses to investigate the association between schizophrenia and epigenetic age accelerations and GrimAge and GrimAge2 components in seven cohorts. Furthermore, we included patients with first-episode psychosis whose illness duration was often shorter than schizophrenia in our analysis. We integrated these results with meta-analyses, noting the acceleration of GrimAge, GrimAge2, and DunedinPACE, and increase in adrenomedullin, beta-2 microglobulin, cystatin C, and plasminogen activation inhibitor-1 levels, in patients with schizophrenia or first-episode psychosis. These results corroborated the finding that patients with schizophrenia had an increased risk of diabetes, cardiovascular disease, and cognitive dysfunction from a biological perspective. Patients with schizophrenia and first-episode psychosis showed differences in the results when compared with controls. Such analyses may lead to the development of novel therapeutic targets to patients with schizophrenia or relevant diseases from the perspective of aging in the future.Nov. 2024, Schizophrenia (Heidelberg, Germany), 10(1) (1), 108 - 108, English, International magazineScientific journal
- AIM: Internet gaming disorder (IGD) is receiving increasing attention. In particular, violent gameplay or in-game spending affects the psychiatric conditions and economic difficulties of patients. We conducted regression analysis and path analysis to investigate the associations between a comprehensive list of factors in patients with IGD, including the degree of internet or gaming dependence, developmental problems, family background, severity of depression, sleeping habits, in-game spending, and first-person shooter (FPS) and third-person shooter (TPS) game playing. METHODS: The participants were 47 Japanese individuals (39 males and 8 females) aged ≤20 years diagnosed with IGD with complete data from the internet addiction test, autism spectrum quotient, Quick Inventory of Depressive Symptomatology, and Pittsburgh Sleep Quality Index. All participants were asked whether their parents have divorce history, whether they have siblings, whether they play FPS or TPS games, and whether they engage in in-game spending. Firstly, we compared these factors between males and females; secondly, we conducted regression analysis and path analysis in male patients. RESULTS: As for simple comparison between sex, female patients showed greater severity of IGD and depressive score. In regression analysis of male patients, significant associations were found between FPS or TPS game playing and in-game spending. We also created path diagrams. CONCLUSION: The results of the comprehensive analyses suggest the possibility that bidirectional synergistic effects could be achieved by gradually reducing both violent game playing and in-game spending. The concept of internet dependence has a wide range of meanings, and for each subtype, it is important to consider the background that led to the dependence to make individualized environmental adjustments and provide psychotherapy.Jul. 2024, Neuropsychopharmacology reports, English, International magazineScientific journal
- Alcohol dependence poses a global health threat associated with aging and reduced life expectancy. Recently, aging research through deoxyribonucleic acid (DNA) methylation has gained attention. New epigenetic clocks have been developed; however, no study has investigated GrimAge components, GrimAge2 components and DunedinPACE in patients with alcohol dependence. In this study, we aimed to perform epigenetic clock analysis to evaluate epigenetic age acceleration and DNA methylation-based age-predictive components in patients with alcohol dependence and controls. We utilized publicly available DNA methylation data (GSE98876) for our analysis. Additionally, we compared the values of the same items before and after the patients underwent a treatment program. The dataset comprised 23 controls and 24 patients. We observed that DunedinPACE accelerated more in patients with alcohol dependence. AgeAccelGrim and AgeAccelGrim2 decelerated more after the treatment program than before, and beta-2-microglobulin and Cystatin C decreased after the treatment program than before. These findings are crucial as they affect the cranial nerve area, potentially contributing to cognitive dysfunction and psychiatric symptoms in patients with alcohol dependence.May 2024, Journal of psychiatric research, 173, 175 - 182, English, International magazineScientific journal
- BACKGROUND: More than 800 000 people die by suicide annually. The heritability of suicide is 30%-50%. We focused on the hypoxia response element (HRE), which promotes the expression of macrophage migration inhibitory factor (MIF) via the hypoxia-inducible factor (HIF) pathway, important in neurogenesis and neuroprotection. We examined a genetic polymorphism of rs17004038, a single-nucleotide polymorphism (SNP), in suicide completers and controls. METHODS: The study population included 1336 suicide completers and 814 unrelated healthy controls. All participants were Japanese. We obtained peripheral blood, extracted DNA, and genotyped the patients for SNP rs17004038 (C > A). RESULTS: No significant differences were observed between the two groups in either the allele or genotype analyses. Subgroup analyses by sex, age (<40 or ≥40), and suicide method (violent or nonviolent suicide) were performed with similar results. CONCLUSION: No association was observed between SNP rs17004038 and suicide completion. Although it is challenging to collect a large number of samples from suicide completers, further MIF-related genetic studies, including those of rs17004038, are necessary with larger sample sizes.Mar. 2024, Neuropsychopharmacology reports, 44(1) (1), 262 - 266, English, International magazineScientific journal
- Repeated abuse of methamphetamine (METH) can cause dependence, repeated relapse of psychotic symptoms, compulsive drug-seeking behaviour, and various neurological symptoms. These long-term biological changes may be associated with epigenetic mechanisms; however, the association between METH use and epigenetic mechanisms has been poorly investigated. Thus, we performed an epigenome-wide association study of METH dependence using genomic DNA extracted from the blood samples of 24 patients with METH dependence and 24 normal controls. All participants were of Japanese descent. We tested the association between METH dependence and DNA methylation using linear regression analysis. We found epigenome-wide significant associations at four CpG sites, one of which occurred in the CNOT1 gene and another in the PUM1 gene. We especially noted the CNOT1 and PUM1 genes as well as several other genes that indicated some degree of association with METH dependence. Among the relatively enriched Gene Ontology terms, we were interested in terms of mRNA metabolism, respirasome, and excitatory extracellular ligand-gated ion channel activity. Among the relatively enriched Kyoto Encyclopedia of Genes and Genome pathways, we noted pathways of several neurological diseases. Our results indicate that genetic changes akin to those in other psychiatric or neurodegenerative disorders may also occur via epigenetic mechanisms in patients with METH dependence.Mar. 2024, Addiction biology, 29(3) (3), e13383, English, International magazineScientific journal
- Major depressive disorder (MDD) is known to cause significant disability. Genome-wide DNA methylation (DNAm) profiles can be used to estimate biological aging and as epigenetic clocks. However, information on epigenetic clocks reported in MDD patients is inconsistent. Since antidepressants are likely confounders, we evaluated biological aging using various DNAm-based predictors in patients with MDD who had never received depression medication. A publicly available dataset consisting of whole blood samples from untreated MDD patients (n = 40) and controls (n = 40) was used. We analyzed five epigenetic clocks (HorvathAge, HannumAge, SkinBloodAge, PhenoAge, and GrimAge), DNAm-based telomere length (DNAmTL), and DNAm-based age-related plasma proteins (GrimAge components), as well as DNAm-based white blood cell composition. The results indicate that patients with untreated MDD were significantly associated with epigenetic aging acceleration in HannumAge and GrimAge. Furthermore, a decrease in natural killer cells, based on DNAm, was observed in patients with untreated MDD.Sep. 2023, npj aging, 9(1) (1), 19 - 19, English, International magazineScientific journal

- (1) Background: The COVID-19 pandemic has distressed many populations worldwide, and since its beginning, many institutes have performed cross-sectional studies to assess mental health. We longitudinally examined psychological distress and depressive symptoms among university staff in Japan from 2019 to 2021, before and during the COVID-19 pandemic.; (2) Methods: Participants were teachers and hospital staff working at institutions related to Kobe University, who completed the Brief Job Stress Questionnaire (BJSQ) from 2019 to 2021. This study used the definition recommended by the guideline to identify high-stress. We analyzed the relationship between those who identified as having high-stress before versus during the COVID-19 pandemic using logistic regression analysis (adjusted for age, sex, and occupation).; (3) Results: Results showed that Stress Reaction scores increased slightly in 2020 and significantly in 2021. Time and other factors had a synergistic effect on mental health. The increase in Stress Reaction was significantly associated with females and nurses over the three years. Those with high-stress in 2019 had approximately twenty-fold odds ratios (OR) of having high-stress in 2020 and 2021.; (4) Conclusions: The long-term COVID-19 pandemic may disturb university staff's mental health. Those who originally experienced high levels of stress were vulnerable to the negative effects of the COVID-19 pandemic.Jan. 2023, International journal of environmental research and public health, 20(3) (3), English, International magazineScientific journal

- MicroRNAs (miRNAs) have been investigated in neurodevelopmental and psychiatric disorders including schizophrenia (SZ). Previous studies showed miRNAs dysregulation in postmortem brain tissues and peripheral blood of SZ patients. These suggest that miRNAs may play a role in the pathophysiology of SZ and be a potential biomarker of SZ. Previous studies also showed that miRNAs regulated neurogenesis and that neurogenesis was involved in the pathophysiology of SZ. In addition, a recent study showed that miR-19a and 19b, enriched in neural progenitor cells (NPC) in adult hippocampus, were increased in human NPC derived from induced pluripotent stem cell derived from SZ patients. However, it remains unclear whether the levels of miR-19a and 19b are altered in peripheral blood of SZ patients and how miR-19a and 19b affects neurogenesis. To elucidate them, first we examined the levels of miR-19a and 19b in peripheral blood of SZ patients with quantitative RT-PCR and showed that the level of miR-19b, but not miR-19a, was significantly higher (miR-19a: p = 0.5733, miR-19b: p = 0.0038) in peripheral blood of SZ patients (N = 22) than that of healthy controls (N = 19). Next, we examined the involvement of miR-19b in proliferation and survival of mouse neonatal mice hippocampus-derived NPC with BrdU assay and TUNEL assay. The silencing of miR-19b significantly increased proliferation (N = 5, p = 0.0139), but not survival (N = 5, p = 0.9571), of neonatal mice hippocampus-derived NPC. These results suggest that the level of miR-19b in peripheral blood is a potential biomarker of schizophrenia and that the higher level of miR-19b may increase the vulnerability of SZ via attenuating proliferation of hippocampal NPC.Dec. 2020, Journal of psychiatric research, 131, 102 - 107, English, International magazineScientific journal

- The accelerated aging hypothesis of schizophrenia (SCZ) has been proposed. DNA methylation profiles were developed for determining "epigenetic age." Here, we assessed intrinsic and extrinsic epigenetic age acceleration (IEAA and EEAA, respectively) in SCZ. We examined two independent cohorts of Japanese ancestry. The first cohort consisted of 80 patients with SCZ under long-term or repeated hospitalization and 40 controls, with the economical DNA pooling technique. The second cohort consisted of 24 medication-free patients with SCZ and 23 controls. Blood of SCZ subjects exhibited decreased EEAA in the first cohort (p = 0.0162), but not in the second cohort. IEAA did not differ in either cohort. We performed replication analyses using publicly available datasets from European ancestry (three blood and one brain datasets). One blood dataset showed increased EEAA in SCZ (p = 0.0228). Overall, our results provide evidence for decreased EEAA in SCZ associated with hospitalization in the Japanese population.Feb. 2019, NPJ schizophrenia, 5(1) (1), 4 - 4, English, International magazine[Refereed]
- Numerous evidence indicated mitochondrial abnormalities in the pathophysiology of bipolar disorder (BD); however, it remains unclear whether aberrant mitochondrial DNA (mtDNA) copy number (cn) occur in BD due to the conflicting results in previous studies. Here, peripheral blood mtDNAcn in 69 BD patients and 54 controls were analysed via qPCR. BD patients had significantly lower mtDNAcn compared to controls (regardless of their BD type [BD I or II]). Meta-analysis for all previous BD-mtDNAcn studies combining our results with previously published studies failed to identify any significant association. Meanwhile, Asian-specific meta-analysis remarkably revealed lower mtDNAcn in BD patients.Nov. 2018, Psychiatry research, 269, 115 - 117, English, International magazine[Refereed]Scientific journal
- Background: Alcohol dependence induces low bone mineral density (BMD), predicting osteoporosis, while low and moderate alcohol consumption may even increase BMD. In recent years, undercarboxylated osteocalcin (ucOC) and tartrate-resistant acid phosphatase-5b (TRACP-5b), bone turnover markers, have gained special interest as useful indicators of low BMD. However, it remains unclear whether other alcohol-related variables (eg, duration of abstinence and continuous drinking) are linked to aberrant BMD. In addition, no previous study has investigated whether ucOC or TRACP-5b is clinically useful to predict low BMD not only in the general population, but also in alcohol-dependent subjects. Patients and methods: We recruited 275 male alcohol-dependent subjects and collected information about their drinking habits, comorbid diseases, smoking history and walking exercise behavior. BMD in each subject was determined by ultrasonography. Serum liver enzymes (AST, ALT, ALP, ChE, γ-GTP and LDH), ucOC and TRACP-5b were measured in all subjects. T-scores were calculated according to BMD for all subjects. Results: The mean T-scores of our subjects were negatively shifted compared to the general population (-0.75±1.36 SD). We divided our subjects into a normal BMD group (n=137) and a low BMD group (n=138) according to their T-scores (T-score ≥-1 SD, normal BMD; T-score <-1 SD, low BMD). Multivariate logistic regression analysis showed that body mass index (BMI) was negatively associated with low BMD (95% CI: 0.75-0.90). By contrast, long abstinence period (95% CI: 1.40-4.21), smoking (95% CI: 1.30-5.56), hypertension (95% CI: 1.04-3.76), lactate dehydrogenase (LDH) (95% CI: 1.00-1.01) and ucOC (95% CI: 1.04-1.22) were positively associated with low BMD. Conclusion: In alcohol-dependent males, smoking habits and higher ucOC are associated with low BMD. Our study suggests that smoking cessation may prevent lower BMD, and ucOC may predict lower BMD in alcohol-dependent individuals.Feb. 2018, Neuropsychiatr Dis Treat, 14, 663 - 669, English, International magazine[Refereed]Scientific journal

- Short telomere length (TL) occurs in individuals under psychological stress, and with various psychiatric diseases. Recent studies have also reported mitochondrial DNA copy number (mtDNAcn) alterations under several neuropsychiatric conditions. However, no study has examined whether aberrant TL or mtDNAcn occur in completed suicide, one of the most serious outcomes of mental illnesses. TL and mtDNAcn in post-mortem samples from 528 suicide completers without severe physical illness (508 peripheral bloods; 20 brains) and 560 samples from control subjects (peripheral bloods from 535 healthy individuals; 25 post-mortem brains) were analysed by quantitative polymerase chain reaction. Suicide completers had significantly shorter TL and higher mtDNAcn of peripheral bloods with sex/age-dependent differences (shorter TL was more remarkably in female/young suicides; higher mtDNAcn more so in male/elderly suicides). The normal age-related decline of TL and mtDNAcn were significantly altered in suicide completers. Furthermore, shorter TL and lower mtDNAcn of post-mortem prefrontal cortex were seen in suicide completers compared to controls. This study shows the first association of aberrant telomeres and mtDNA content with suicide completion. Our results indicate that further research on telomere shortening and mitochondrial dysfunction may help elucidate the molecular underpinnings of suicide-related pathophysiology.NATURE PUBLISHING GROUP, Jun. 2017, SCIENTIFIC REPORTS, 7(1) (1), 3176, English[Refereed]Scientific journal

- Background: Numerous studies suggest that inflammation plays a key role in suicidal behavior. Macrophage migration inhibitory factor (MIF), a proinflammatory cytokine, has received increasing attention in depression research. However, no study has investigated whether MIF has genetic involvement in completed suicide. In this study, we sought to explore the relationship between two functional polymorphisms on the MIF gene promoter (MIF-794CATT(5-8) microsatellite and MIF-173G/C single-nucleotide polymorphism [ SNP]) and completed suicide by using one of the largest samples of suicide completers ever reported. Methods: The subjects comprised 602 suicide completers and 728 healthy controls. We genotyped MIF-794CATT(5-8) microsatellite by polymerase chain reaction-based size discrimination assay and MIF-173G/C SNP by TaqMan((R)) SNP genotyping assay. The allele-, genotype-, or haplotype-based association analyses between the suicide completers and the controls were carried out with the chi(2) test, the Cochran-Armitage trend test, or Fisher's exact test. Results: Analyses of allele or genotype frequency distributions of the polymorphisms studied here did not reveal any significant differences between the suicide completers and the controls. Haplotype analysis also revealed no association with completed suicide. Conclusion: To our knowledge, this is the first study that has examined the genetic association between MIF and completed suicide. Our results suggest that the effects of MIF-794CATT(5-8) microsatellite and MIF-173G/C SNP on the MIF gene promoter might not contribute to the genetic risk of completed suicide in the Japanese population.DOVE MEDICAL PRESS LTD, 2017, NEUROPSYCHIATRIC DISEASE AND TREATMENT, 13, 899 - 908, EnglishScientific journal
- Background: Recent studies suggest that genomic abnormalities such as single nucleotide polymorphisms (SNPs) and copy number variations (CNVs) may elevate the risk of schizophrenia. Such genomic abnormalities often occur during chromosomal DNA replication in the S phase of cell cycle. In addition, several studies showed that abnormal expressions of several cell cycle-related genes are associated with schizophrenia. Therefore, here we compared mRNA expression levels of cell cycle-related genes in peripheral blood cells between patients with schizophrenia and healthy controls. Method: mRNA expression levels of cell cycle-related genes in peripheral blood cells from patients with schizophrenia and healthy controls were measured with quantitative reverse transcription polymerase chain reaction (Q-RT-PCR). The discovery, replication and intervention studies with Q-RT-PCR were performed as follows: discovery (40 cases and 20 controls), replication (82 cases and 74 controls) and intervention (22 cases and 18 controls). Result: Nine genes were identified in the discovery and replication stages as schizophrenia-associated genes. Moreover, the combination of mRNA expression levels of CDK4, MCM7 and POLD4 was identified as a potential biomarker for schizophrenia with multivariate logistic regression analysis. The intervention stage revealed that the mRNA expression levels of these three genes were significantly decreased in the acute state of schizophrenia, and CDK4 was significantly recovered in the remission state of schizophrenia. Conclusion: The combination of mRNA expression levels of three cell cycle-related genes such as CDK4, MCM7 and POLD4 is expected to be a candidate for useful biomarkers for schizophrenia. Especially, the mRNA expression changes of CDK4 may be potential as both trait and state markers for schizophrenia. (C) 2016 Elsevier Inc.

- BACKGROUND AND AIM: Alcoholic liver disease (ALD) is the most common cause of hepatocellular carcinoma (HCC) worldwide. Des-gamma-carboxy prothrombin (DCP) is elevated in many patients with HCC, but also in severe alcoholics without HCC. We aimed to clarify whether the DCP/NX-DCP ratio (NX-DCP-R) could have a high specificity in ALD patients without HCC. METHODS: We performed a prospective cohort study on a total of 703 consecutive outpatients of liver diseases including severe alcoholics and healthy volunteers, who underwent blood biochemical examinations at Kobe University Hospital. Serum DCP was measured by electrochemiluminescence immunoassay (ECLIA) using a monoclonal antibody, MU-3. A novel parameter, serum NX-DCP, which represents predominantly DCP caused by reduced vitamin K availability, was also measured by ECLIA using monoclonal antibodies P-16 and P-11. The diagnostic accuracy of DCP and NX-DCP-R in patients with and without excessive alcohol intake was statistically examined. RESULTS: DCP was significantly higher in alcoholics than in non-alcoholics (p= 0.005), whereas the NX-DCP-R did not differ between alcoholics and non-alcoholics (p= 0.375). DCP was significantly increased in the serum of each patient with alcoholic hepatitis and alcoholic cirrhosis (p< 0.05), whereas the NX-DCP-R was not increased (p> 0.05). CONCLUSIONS: NX-DCP-R, but not DCP, was not increased in alcoholics without HCC. As for negative screening for HCC, the specificity of the NX-DCP-R in alcoholics without HCC was better than that of DCP in alcoholics without HCC, and so could be a useful negative screening tool for HCC in millions of alcoholics worldwide.2016, Cancer biomarkers : section A of Disease markers, 16(1) (1), 171 - 80, English, International magazineScientific journal
- It has been shown that the dysfunction of N-methyl-D-asparate (NMDA) receptors-mediated neurotransmission plays a role in the pathophysiblogy of schizophrenia. Especially, GluN2B, a subunit of NMDA receptors, associated trafficking complex is altered in the prefrontal cortex of schizophrenia. The kinesin superfamily motor protein 17 (KIF17) is known as a transporter of NR2B.Previous studies showed that a structural variant of KIF17 gene is associated with a schizophrenic phenotype. Therefore, here we investigated KIF17 levels in postmortem prefrontal cortex in schizophrenia and the association of a missense polymorphism (Ile341Val) in KIF17 with schizophrenia. The protein expression of KIF17 in schizophrenic postmortem brains was significantly lower than that in controls. Next, the association of missense polymorphisms (rs631375, rs13375609, rs522496 and rs2296225) of KIF17 gene in 567 schizophrenia and 710 healthy subjects was examined. Both genotypic distribution and allelic frequency of rs2296225 polymorphism were significantly different between the chronic schizophrenia subjects and controls. However, our findings described above were not replicated with the independent subjects (555 schizophrenia and 814 healthy controls). Furthermore, the two alleles of rs2296225 polymorphism did not affect the mRNA expression of KIF17. These results suggest that the dysfunction of KIF17 might be involved in the pathophysiology of schizophrenia. (C) 2015 Elsevier Ireland Ltd.

- Background: Cadherin13 (CDH13) is a glycosylphosphatidylinositol-anchored cell adhesion molecule that plays a crucial role in morphogenesis and the maintenance of neuronal circuitry. CDH13 has been implicated in the susceptibility to a variety of psychiatric diseases. A recent genome-wide association study using Danish samples showed, for the first time, the involvement of a single nucleotide polymorphism (SNP) of CDH13 (intronic SNP rs8057927) in schizophrenia. Here, we investigated the association between other SNPs of CDH13 and schizophrenia and tried to replicate the association for the SNP of rs8057927, in the Japanese population. Methods: Using TaqMan (R) SNP genotyping assays, five tag SNPs (rs12925602, rs7193788, rs736719, rs6565051, and rs7204454) in the promoter region of CDH13 were examined for their association with schizophrenia in two independent samples. The first sample comprised 665 patients and 760 controls, and the second sample comprised 677 patients and 667 controls. One tag SNP for rs8057927 was also examined for the association with schizophrenia in the first sample set. Results: A GACAG haplotype of the five SNPs in the promoter region of CDH13 was significantly associated with schizophrenia in the first sample set (P=0.016 and corrected P=0.098). A combined analysis of the GACAG haplotype with the second sample set enhanced the significance (P=0.0026 and corrected P=0.021). We found no association between rs8057927 and schizophrenia in the first sample set. Conclusion: Our results suggest that CDH13 may contribute to the genetic risk of schizophrenia. Further replication on the association of CDH13 with schizophrenia and functional studies are required to confirm the current findings.DOVE MEDICAL PRESS LTD, 2015, NEUROPSYCHIATRIC DISEASE AND TREATMENT, 11, 1381 - 1393, English[Refereed]Scientific journal

- Background: Genome-wide association studies (GWAS) and gene expression analyses have revealed that single nucleotide polymorphisms (SNPs) associated with multifactorial diseases, such as schizophrenia, are significantly more likely to be associated with expression quantitative trait loci (eQTL). It was recently suggested that an immune system imbalance plays an important role in the pathogenesis of schizophrenia. Interleukin-19 is a novel cytokine that may play multiple roles in immune regulation and various diseases. Method: We selected eight tag SNPs in the eQTL of the IL-19 gene. Seven of the SNPs are putative cis-acting SNPs. Then, we conducted a case-control study using two independent samples. The first sample comprised 567 schizophrenia patients and 710 controls, and the second sample comprised 677 schizophrenia patients and 667 controls. Result: We identified the TGAA haplotype as being significantly associated with schizophrenia (p = 0.0036 and corrected p = 0.0264), although a combined analysis of the TGAA haplotype with the replication samples exhibited a nominally significant difference (p = 0.022 and corrected p = 0.235). Conclusions: These results suggest that the IL-19 gene might slightly contribute to the genetic risk of schizophrenia. Thus, further research on the association of eQTL SNPs with schizophrenia is warranted. (C) 2013 Elsevier Inc.

- The present study investigated the genetic association of the disrupted-in-schizophrenia 1 (DISCI) gene with suicide using 398 Japanese completed suicides and 511 healthy controls. The functional Ser704Cys variant of DISCI was nominally associated with completed suicide. Enhanced evidence of association was observed in a multi-marker sliding window haplotype analysis (the lowest p=0.002). These findings warrant further studies with a larger sample size to confirm the association of DISCI with suicide. (C) 2013 Elsevier Ireland Ltd.

- The Disrupted-in-Schizophrenia 1 (DISC1) gene plays a role in the regulation of neural development. Previous evidence from genetic association and biological studies implicates the DISC1 gene as having a role in the pathophysiology of schizophrenia. In the present study, we explored the association between DISCI missense mutation rs821616 (Ser704Cys) single nucleotide polymorphism (SNP) and four other SNPs (rs1772702, rs1754603, rs821621, rs821624) in the related haplotype block and schizophrenia in the Japanese population. We could not find a significant association of selected SNPs with schizophrenia after correction for multiple testing. We performed a meta-analysis of the Ser704Cys variant in schizophrenia using data from the present study and five previous Japanese population studies, and found no association with schizophrenia. We also examined DISCI immunoreactivity in postmortem prefrontal cortex specimens of schizophrenia patients compared to control samples. The immunoreactivity revealed a significant decrease of DISCI protein expression in the schizophrenia samples after ruling out potential confounding factors. However, the Ser704Cys variant did not show effects on DISCI immunoreactivity. These results provide evidence that this functional genetic variation of DISC1 do not underlie the pathophysiology of schizophrenia in the Japanese population.

Patients often develop delirium after cardiovascular surgery. To determine the association of the preoperative use of statins with a reduced incidence of post-operative delirium, we retrospectively collected data from 324 patients who underwent cardiac and aortic surgery at our hospital from July 2011 through June 2012. The incidence of postoperative delirium significantly decreased in patients who were administered statins preoperatively. Based on the data collected, emergency surgeries, advanced age, and longer operation time were further indicated predictors of postoperative delirium. These results indicate that preoperative administration of statins decreases the risk of delirium after cardiac and aortic surgery, by possibly protecting the central nervous system.
[Refereed]Scientific journal - Background: Cell adhesion molecules (CAMs) play pivotal role in the development of the central nervous system (CNS) and have also been reported to play role in the pathophysiology of schizophrenia. Missense mutations in the CAMs genes might alter the binding of their ligands, increasing the vulnerability to develop schizophrenia. Methods: We selected 15 missense mutations in the CAMs genes of the CNS reported in the Kyoto Encyclopedia of Genes and Genomes (KEGG) and examined the association between these mutations and schizophrenia in 278 patients and 284 control subjects (first batch). We also genotyped the positive single nucleotide polymorphisms (SNPs) in 567 patients and 710 control subjects (second batch) and in 635 patients and 639 control subjects (replication samples). Results: Genotypic and allelic distributions of rs2298033 in the ITGA8 gene between the schizophrenia and control groups were significantly different in the first batch (p = 0.005 and 0.007, respectively). Gender-based analysis revealed that the allelic and genotypic distributions of rs2298033 in the ITGA8 were significantly different between the schizophrenia and control groups among females in both batches (p = 0.010, 0.011 and 0.0086, 0.010, respectively) but not among males. Combine analysis of rs2298033 with the replication samples revealed a more significant differences (p = 0.0032; 0.0035 in the overall subjects and p = 0.0024; 0.0025 in the female subjects, respectively). The significant differences for rs2802808 of the NFASC gene were only observed in the female subgroup of the first batch. Conclusion: These results suggest that the ITGA8 gene might have gender-specific roles in the development of schizophrenia. Further replication and functional studies are required to confirm these findings. (c) 2012 Elsevier Inc.

- Recent genome-wide association study (GWAS) and gene expression analyses have revealed that single nucleotide polymorphisms (SNPs) associated with complex diseases such as schizophrenia are significantly more likely to be associated with expression quantitative trait loci (eQTL). The interleukin-1 beta (IL1B) gene has been strongly implicated in the susceptibility to schizophrenia. In order to test this association, we selected five tag SNPs in the eQTL of the IL1B gene and conducted a case-control study using two independent samples. The first sample comprised 528 schizophrenic patients and 709 controls and the second sample comprised 576 schizophrenic patients and 768 controls. We identified two SNPs and several haplotypes as being significantly associated with schizophrenia. Previous reports indicated that one major haplotype that was protective against schizophrenia reduced IL1B transcription, while two risk haplotypes for schizophrenia enhanced IL1B transcription. Therefore, we measured IL1B mRNA expression in PAXgene-stabilized whole blood from 40 schizophrenic patients and 40 controls to explore the possibility of using five tag SNPs as schizophrenic trait markers. A multiple regression analysis taking confounding factors into account revealed that the T allele of rs4848306 SNP, which is a protective allele for schizophrenia, predicted reduced change in IL1B mRNA expression, regardless of phenotype. Our results appear to support the previous hypothesis that IL1B contributes to the genetic risk of schizophrenia and warrant further research on the association of eQTL SNPs with schizophrenia.

- Aims: In order for hospitals to work efficiently in a pandemic, it is important to know how a pandemic affects the hospital staff. The aim of the present study was to investigate the psychological impact of the pandemic (H1N1) 2009 on hospital workers and how it was affected by the characteristics of the hospital, gender, age, job and work environment. Methods: In late June 2009, soon after the pandemic had ended in Kobe city, Japan, a questionnaire was distributed consisting of questions on sociodemographic characteristics, 19 stress-related questions and the Impact of Event Scale (IES) to all 3635 employees at three core general hospitals in Kobe. Exploratory factor analysis was applied to the 19 stress-related questions, and this produced four factors for evaluation (anxiety about infection, exhaustion, workload, and feeling of being protected). Multiple regression models were used to evaluate the association of personal characteristics with each score of the four factors and the IES. Results: Valid answers were received from 1625 employees. Workers at a hospital with intense liaison psychiatric services felt less psychological impact. Workers at a hospital that provided staff with information about the pandemic less frequently, felt unprotected. Workers in work environments that had a high risk of infection felt more anxious and more exhausted. The total IES score was higher in workers in high-risk work environments. Conclusions: It is important for hospitals to protect hospital workers during a pandemic and to rapidly share information about the pandemic. Liaison psychiatric services can help to reduce the impact of the pandemic on hospital workers.WILEY-BLACKWELL, Jun. 2012, PSYCHIATRY AND CLINICAL NEUROSCIENCES, 66(4) (4), 353 - 360, English[Refereed]Scientific journal

- Background: The professionalism of hospital workers in Japan was challenged by the pandemic (H1N1) 2009. To maintain hospital function under critical situations such as a pandemic, it is important to understand the factors that increase and decrease the willingness to work. Previous hospital-based studies have examined this question using hypothetical events, but so far it has not been examined in an actual pandemic. Here, we surveyed the factors that influenced the motivation and hesitation of hospital workers to work in Japan soon after the pandemic (H1N1) 2009. Methods: Self-administered anonymous questionnaires about demographic character and stress factors were distributed to all 3635 employees at three core hospitals in Kobe city, Japan and were collected from June to July, 2009, about one month after the pandemic (H1N1) in Japan. Results: Of a total of 3635 questionnaires distributed, 1693 (46.7%) valid questionnaires were received. 28.4% (N = 481) of workers had strong motivation and 14.7% (N = 249) had strong hesitation to work. Demographic characters and stress-related questions were categorised into four types according to the odds ratios (OR) of motivation and hesitation to work: some factors increased motivation and lowered hesitation; others increased motivation only; others increased hesitation only and others increased both motivation and hesitation. The strong feeling of being supported by the national and local governments (Multivariate OR: motivation; 3.5; CI 2.2-5.4, hesitation; 0.2; CI 0.1-0.6) and being protected by hospital (Multivariate OR: motivation; 2.8; CI 2.2-3.7, hesitation; 0.5; CI 0.3-0.7) were related to higher motivation and lower hesitation. Here, protection included taking precautions to prevent illness among workers and their families, providing for the care of those who do become ill, reducing malpractice threats, and financial support for families of workers who die on duty. But 94.1% of the respondents answered protection by the national and local government was weak and 79.7% answered protection by the hospital was weak. Conclusions: Some factors have conflicting effects because they increase both motivation and hesitation. Giving workers the feeling that they are being protected by the national and local government and hospital is especially valuable because it increases their motivation and lowers their hesitation to work.BIOMED CENTRAL LTD, Nov. 2010, BMC PUBLIC HEALTH, 10, 672, English[Refereed]Scientific journal
- Schizophrenia is a devastating neurodevelopmental disorder whose genetic influences remain elusive. Recent genome-wide scans revealed that rare structural variants disrupted multiple genes in neurodevelopmental pathways, which strongly implicate nitric oxide (NO) signaling in schizophrenia. NO acts as a second messenger of N-methyl-D aspartate receptor activation, which further interacts with both dopaminergic and serotonergic pathways. NO is mainly synthesized by neuronal nitric oxide synthase (NOS1) in the brain, and its gene locus, 12q24.2, has attracted much attention as a major linkage region for schizophrenia. Genetic variations of NOS1 have also been associated with schizophrenia, and differential expression of NOS1 was observed in the postmortem brain of schizophrenic patients. Here, we explored the hypothesis that a putative cis-acting G-84A single nucleotide polymorphism (SNP; rs41279104) in the exon 1c promoter region of the NOS1 gene is associated with the levels of NOS1 immunoreactivity in postmortem prefrontal cortex specimens regardless of disease phenotype. Individuals with the A-allele of this SNP showed significantly lower levels of NOS1 immunoreactivity than did GG homozygotes (p=0.002). Furthermore, a case-control study using 720 individuals in a Japanese population revealed a significant association between the SNP and schizophrenia (genotypic p=0.0013 and allelic p=0.0011). Additionally, the average of onset age in schizophrenic patients with the A-allele was significantly earlier than GG homozygotes (p=0.018). When the analyses took gender into account, this significance was more significant for female. These findings provide further evidences that NOS1 is associated with a biological susceptibility gene to schizophrenia. (C) 2010 Elsevier B.V.

- Epidemiological studies have shown that excessive alcohol consumption is a potent risk factor to develop suicidal behavior. Genetic factors for suicidal behavior have been observed in family, twin, and adoption studies. Because alcohol dehydrogenase (ADH1B) His47Arg and mitochondrial aldehyde dehydrogenase (ALDH2) Glu487Lys single nucleotide polymorphisms (SNPs), which affect alcohol metabolism, have been reported to exert significant impacts on alcohol consumption and on the risk for alcoholism in East Asia populations, we explored associations of the two functional SNPs with suicide using a case-control study of 283 completed suicides and 319 control subjects in the Japanese population. We found that the inactive ALDH2 allele (487Lys) was significantly less frequent in the completed suicides (19.3%) than in the controls (29.3%), especially in males, whereas this was not the case in females. The males bearing alcoholism-susceptible homozygotes at both loci (inactive ADH1B Arg/Arg and active ALDH2 Glu/Glu genotypes) have a 10 times greater risk for suicide compared with the males bearing alcoholism-protective homozygotes at both loci. Our data show the genetic impact of the two polymorphisms on suicidal behavior in the Japanese population, especially in males. Because we did not verify the daily alcohol consumption, the association of these SNPs with suicide might be due to alcoholism itself. Further studies using case-control subjects, which verifies the details of current and past alcohol consumption and diagnosis for alcoholism, are required to confirm these findings.WILEY, Jul. 2010, GENES BRAIN AND BEHAVIOR, 9(5) (5), 498 - 502, English[Refereed]Scientific journal
- Association study of RGS2 gene polymorphisms with panic disorder in JapaneseGenetic factors for panic disorder have been consistently observed in family andtwin studies. Regulators of G-protein signaling (RGS) is a family of proteins thatnegatively regulate the intracellular signaling of G protein-coupled receptors such asdopamine and serotonin receptors. RGS2, one of the RGS families, has been suggestedto plays a role in anxiety and/or aggressive behavior. Polymorphisms in the RGS2 genewere recently associated with panic disorder, trait anxiety, suicidal behavior, andgeneralized anxiety disorder. From these findings, we tried to replicate an associationbetween panic disorder and genetic variations of the RGS2 using a case-control study of186 patients with panic disorder and 380 controls in Japanese. We genotyped fivecommon single nucleotide polymorphisms (SNPs) by the PCR-RFLP method and theTaqMan Assays. Neither genotype distribution nor allele frequency for five SNPs wassignificant different between the panic disorder and control groups. We found arelative tight LD block in the 5'- flanking region of RGS2 gene. One of the commonhaplotypes, AC of rs2746071 and rs2746072, has shown a nominally significantassociation with panic disorder (p=0.027). This significance, however, did not remainafter correction for multiple testing. These findings suggest that RGS2 may not begenetically involved in the biological susceptibility to panic disorder in Japanese.Kobe University, Apr. 2010, Kobe J Med Sci, 55(5) (5), E116 - 21, English[Refereed]Scientific journal

- BACKGROUND: Serotonergic systems mediate a control of aggression and/or impulsivity in human and are suggested to be involved in suicidal behavior. The newly identified neuronal tryptophan hydroxylase isoform 2 (TPH2), the rate-limiting enzyme in serotonin synthesis, represents a prime candidate in numerous genetic association analyses of suicidal behavior; however, the results are still inconclusive. The discrepancy may result from the heterogeneity of pathogenesis of suicidal behavior and/or methodological mismatches. We, therefore, attempted to replicate the association of TPH2 gene with suicide using a case-control study of 234 completed suicides and 260 control subjects in Japanese population. METHODS: We genotyped 15 tagging-single nucleotide polymorphisms (SNPs) including 4 SNPs, which were previously reported to be associated with suicidal behavior, using the TaqMan probe assays and the polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. RESULTS: We found no significant differences in genotypic distributions (uncorrected p=0.06-0.98) or allelic frequencies (uncorrected p=0.09-0.95) of the fifteen SNPs between the completed suicides and control groups. Haplotypes constructed with these SNPs were also not associated with suicide (uncorrected p=0.03-0.96 and corrected p=0.20-1.00). Even when we took sex and suicidal methods (violent or non-violent) into account for the analyses, no significant differences in genotypic distributions, allelic/haplotypic frequencies were found in the two groups. CONCLUSION: Our results suggest that the common SNPs and haplotypes of the TPH2 gene are unlikely to contribute to the genetic susceptibility to suicidal behavior in Japanese population.Nov. 2009, Progress in neuro-psychopharmacology & biological psychiatry, 33(8) (8), 1546 - 1550, English, International magazine[Refereed]Scientific journal
- A recent linkage study suggested that a putative locus for suicidal behavior independent of psychiatric disease phenotypes lies at 5' upstream of the mu-opioid receptor (OPRM1) gene. We explored an association between suicide and genetic variations of the OPRM1 using a case-control study of 183 completed suicides and 374 control subjects. We genotyped four single nucleotide polymorphisms (SNPs) including a common A118G SNP. The genotypic and allelic distributions of the A118G SNP were significantly different between the completed suicide and control groups (P = 0.014 and 0.039, respectively). A dominant model analysis of the A118G SNP showed an enhanced association with suicide (P = 0.0041, Odds ratio 0.575) and this significant association was observed with a logistic regression analysis that takes sex and age factors into account (P = 0.021).

- 生まれ月(時期)と青年後期における精神的健康及び心理的特性との関連背景)同じ学年内において、生まれ月により学力、運動といった能力に差が出ることが知られている。この差は特に低学年で顕著となり、除々に差が縮まると報告されている。しかし、青年後期での差や、精神的健康状態との関連は未知の部分が多い。今回、大学入学時の学生精神的健康調査(UPI)の結果を用い、生まれ月による青年後期での精神的健康度への影響について検討した。方法)2012年~2021年の10年問における神戸大学新入生のうち、入学時にUPIへの回答を行った18歳~19歳の学部新入生20,423人を解析対象とした。4月2日生まれを先頭とし、3ヵ月毎に4期に分け、生まれた時期とUPIの得点及び副次項目の点数(心気的症状、自律神経症状、抑うつ傾向、対人不安、強迫傾向、被害関係念慮、陽性項目(良好な精神状態))との関連を調べた。また、ポアソン分布を仮定した一般化線形モデルを使用し、共変量を調整した関連についても調べた。結果)生まれた時期と陽性項目4項目の平均点との間に有意な関連がみられた(陽性項目平均点(±SD):第一期0.550(±0.923)、第2期0.520(±0.891、第3期0.527(±0.908)、第4期0.497(±0.889),p<0.01)。他の副次項目及び総得点との間には有意な関連はみられなかった。多変量解析の結果、第4期生まれは第1期生まれに比べ、陽性項目が有意に低くなっていた。(点数比:0.90(95%信頼区間:0.85-0.95,p<0.001))。考察)いわゆる「早生まれ」と呼ばれる、第4四半期生まれの子供は、青年後期において、良好な精神的健康状態が見られにくいことが明らかとなった。一方で、不良な精神的健康度の項目に差はなかった。これらの結果から、早生まれの子供は、自身の精神的健康に対する肯定的認知が低い可能性が考えられ、生育過程での心理的支援の必要性が考えられた。(著者抄録)(NPO)全国大学メンタルヘルス学会, Jun. 2024, 大学のメンタルヘルス, 6, 66 - 67, Japanese

- 既報により、学業状況や人間関係等が大学生のストレス要因となりうることが示されているが、大学生のストレス要因の全容は不明なままである。機械学習によるTwitter等のソーシャルメディアネットワーク(SNS)における感情の抽出方法は発展を遂げている。今回、我々はSNSにおける自然言語処理モデルを用いた感情分析を通して、大学を取り巻く環境でのストレス要因抽出とその評価を試みた。Twitterにおいて、「神戸大学」等のキーワードにより、大学環境に係るツイートを定期的に抽出した。抽出されたツイートの内容を自然言語処理モデルにより解析し、感情極性を評価するとともに、ネガティブと判定されたツイートに関連するキーワードを抽出の上カテゴリー分けを行い、ストレス要因としての評価を行った。2022年4月1日~9月30日において、71191件のツイートが収集され、その内、自動送信と考えられるツイートを除いた52584件を解析の対象とした。感情分析により、ネガティブと判定されたツイートは、2615件(5.0%)であった。含まれる要素の分析を行ったところ、入試、勉学、地域、Twitter、健康、社会情勢、人間関係、サークル活動、アルバイトといったカテゴリーに分類されるキーワードが抽出された。今回の結果では、既報と同様のストレス因に加え、時事的なストレス因についても抽出されていた。今回の方法は、大規模かつ簡便に行うことができ、大学生のストレス因を抽出するツールとなる可能性が示唆された。(著者抄録)(NPO)全国大学メンタルヘルス学会, Dec. 2023, 大学のメンタルヘルス, 7, 76 - 78, Japanese

- Functioning as a regional acute care hospital, our emergency medical center widely accepts patients in primary ~ tertiary emergencies. A preliminary study revealed that 18.5% of all inpatients experience delirium which is similar to the percent reported by other institutes. The study also states that half of falling accidents among the incident cases occurs during periods of delirium. Because delirium greatly complicates medical management, detection and intervention to prevent delirium in its early stage is important. In 2009, we and other medical professionals formed a delirium care team (DCT), whose main goal is the prevention of occurrence and worsening of delirium by early intervention. Our DCT consists of psychiatrists, nurses, pharmacists and physical therapists. DCT members make the rounds of all wards every day, consulting with inpatients with delirium or a high risk of delirium. The DCT arranges medication, reinforces cognitive orientation, estimates pain and educates inpatients and their relatives about delirium. DCT members hold a conference about inpatients with delirium every month. Once a year, an educational conference about delirium is held for the hospital staff. Because many wards rely on DCT activities for a rapid response to delirium, team intervention to prevent delirium can decrease psychological distress of the hospital staff caring for inpatients with delirium. The number of interventions by the DCT has been increasing reaching 413 inpatients in 2011. Based on our recent experience, the DCT has been most successful in preventing the worsening of delirium rather than preventing delirium itself. Because our hospital is obligated to treat emergencies, making the rounds of the wards by the DCT consisting of various medical professions has made a significant contribution to the treatment of delirium.Japanese Society of General Hospital Psychiatry, Apr. 2012, 総合病院精神医学, 24(2号) (2号), 146 - 154, JapaneseIntroduction scientific journal
