RESUMEN
AIM: The aim of this study was to conduct a 5-h training programme on anger-focused emotional management for nurses and verify its effectiveness. DESIGN: The study used a one-group pretest-posttest design. METHODS: Participants (N = 283) attended a programme comprising lectures and exercises. The Japanese version of the Buss-Perry Aggression Questionnaire was administered pre-, post- and 3-month posttraining. Regression analyses were used to assess the effects of the programme by gender. RESULTS: For the total aggression score, the difference between the pre- and posttraining scores was -2.827 points and remained at -1.602 points 3-month posttraining. Physical aggression scores decreased posttraining, but the scores increased after 3 months. There were statistically significant gender differences in hostility scores; pre-training scores were slightly higher for men than for women and lower for men after 3 months. Total and physical aggression scores were higher for men than for women. The training programme decreased aggression, and the effect persisted after 3 months.

INTRODUCTION: Mild cognitive dysfunction has been implicated in a number of psychiatric diseases and affects social functioning. Although clinical criteria were recently proposed for autoimmune psychosis (AP), biomarkers have not yet been established for the severity and prognosis of cognitive dysfunction. We herein investigated the relationships between 3 types of serum antibodies and cognitive dysfunction in chronic psychiatric patients suspected of AP. METHODS: We included 31 patients suspected of AP and obtained information on their clinical characteristics. Three types of autoantibodies (the anti-N-methyl-D-aspartate receptor (anti-NMDAR Ab), anti-N-terminal of GluN1 (anti-GluN1-NT Ab), and anti-thyroid antibodies) were evaluated in serum. Cognitive function was assessed using Wechsler Adult Intelligence Scale-III. We examined the relationships between serum autoantibodies and cognitive dysfunction in patients using multiple regression models. RESULTS: Serum titers of anti-GluN1-NT Ab significantly contributed to the estimated score of working memory (B= -55.85, ß= -0.46, p=â¯0.01), while no correlation was observed between the other 2 types of antibodies and cognitive function. CONCLUSIONS: The present results indicate the potential of serum anti-GluN1-NT Ab as a biomarker for the severity and prognosis of cognitive dysfunction underlying various psychiatric symptoms in patients with AP. The pathological significance of anti-GluN1-NT Ab needs to be verified in future studies.

INTRODUCTION: Hashimoto's thyroiditis, which is characterized by anti-thyroid antibodies such as the anti-thyroglobulin (Tg) antibody and anti-thyroid peroxidase (TPO) antibody, is one of the autoimmune diseases associated with psychiatric illnesses. We previously reported a high prevalence of antibodies to N-terminals of N-methyl-D-aspartate (NMDA) type glutamate receptor (GluR) subunits (GluN1-NT and GluN2B-NT2) among psychiatric patients with anti-thyroid antibodies. However, it remains unclear whether the presence of anti-thyroid antibodies influences antibodies to GluN1-NT or GluN2B-NT2 among psychiatric patients. The present study aims to examine antibodies to GluN1-NT and GluN2B-NT2 in psychiatric patients with anti-thyroid antibodies (PPATs) and in those without (non-PPATs). MATERIAL AND METHODS: We recruited psychiatric inpatients aged 20-60 years. Patients were excluded if they had a history of neurological diseases, dementia, developmental disorders, tumors, or autoimmune diseases except autoimmune thyroiditis. The rest of the participants were divided into two groups according to the presence of serum anti-Tg and anti-TPO antibodies. We investigated serum and cerebrospinal fluid (CSF) antibodies to GluN1-NT and GluN2B-NT2 using an enzyme-linked immunosorbent assay (ELISA). RESULTS: We initially recruited seventy-three psychiatric inpatients. Forty-six patients were excluded because of the exclusion criteria. Eighteen PPATs and nine non-PPATs were ultimately enrolled. We also collected stored sera of eighteen healthy controls (HCs) who were age- and sex-matched with PPATs. The optical densities (ODs) of serum antibodies to GluN1-NT (p = 0.0020) and GluN2B-NT2 (p = 0.039) were significantly higher in PPATs than in HCs. The ODs of CSF antibodies to GluN1-NT (p = 0.030) and GluN2B-NT2 (p = 0.017) as well as the positive ratios of those antibodies were significantly higher in PPATs than in non-PPATs. CONCLUSION: Our finding indicates that detecting anti-thyroid antibodies in psychiatric patients would be a clue to consider psychiatric conditions related to antibodies to GluN1-NT/GluN2B-NT2. Further studies focusing on the relationship between PPATs and antibodies to GluN1-NT/GluN2B-NT2 are needed.
RESUMEN
OBJECTIVE: The present study investigated the effects of plasma matrix metalloproteinases (MMPs) on longitudinal changes in Alzheimer's disease (AD)-related biomarkers in cerebrospinal fluid (CSF), brain atrophy, and cognitive function in patients with mild cognitive impairment due to AD (MCI-AD). METHODS: We used data from the Alzheimer's Disease Neuroimaging Initiative database. We included 95 ApoE4-positive patients with MCI-AD who were confirmed to have low Aß42 and/or high phosphorylated-tau (p-tau) in CSF. We obtained baseline demographic data, plasma MMP levels, including MMP-1, -2, -7, -9, -10, and tissue inhibitor of MMP-1 (TIMP-1), longitudinal annual data on Aß42, total tau, and p-tau in CSF, MRI-measured hippocampal volumes, and cognitive function evaluated by the Mini-Mental State Examination (MMSE) and AD Assessment Scale-11 (ADAS-11) over 4 years. We examined the effects of baseline MMP levels on longitudinal changes in CSF AD biomarkers, hippocampal volumes, and cognitive function using a linear mixed regression analysis. RESULTS: No significant differences were observed in baseline plasma MMP levels between MCI-AD patients and control subjects, except for MMP-10, which was significantly lower in MCI-AD than in controls. The baseline levels of MMPs did not correlate with longitudinal changes in CSF biomarkers. Declines in hippocampal volumes and cognitive function evaluated by MMSE and ADAS-11 were significantly faster in MCI-AD patients with high-MMP-9 levels at baseline than in those with middle and low MMP-9 levels at baseline. CONCLUSION: High plasma MMP-9 levels in MCI-AD patients might enhance neurodegeneration and cognitive decline.

We report a case of probable dementia with Lewy bodies (DLB) with several findings indicating autoimmune encephalitis (e.g. anti-thyroid antibodies in serum and oligoclonal band and anti-N-methyl-d-aspartic acid receptor antibodies in cerebrospinal fluid). The symptoms and the findings of ancillary tests such as Iodine-123-metaiodobenzylguanidine myocardial scintigraphy and 99mTechnetium-ethyl-cysteinate-dimer single photon emission computed tomography were improved after the pulse and oral steroid treatment. This case is thought the autoimmune encephalitis mimicking DLB. This experience indicated the importance of suspecting treatable DLB even when the findings of laboratory and radiological tests fulfill the diagnostic criteria of DLB.

OBJECTIVES: Depression is frequently observed in patients with systemic lupus erythematosus (SLE). Neuropsychiatric SLE (NPSLE) patients often exhibit cerebral hypometabolism, but the association between cerebral metabolism and depression remains unclear. To elucidate the features of cerebral metabolism in SLE patients with depression, we performed brain 18F-fluoro-d-glucose positron emission tomography (FDG-PET) on SLE patients with and without major depressive disorder. METHODS: We performed brain FDG-PET on 20 SLE subjects (5 male, 15 female). The subjects were divided into two groups: subjects with major depressive disorder (DSLE) and subjects without major depressive disorder (non-DSLE). Cerebral glucose metabolism was analyzed using the three-dimensional stereotactic surface projection (3D-SSP) program. Regional metabolism was evaluated by stereotactic extraction estimation (SEE), in which the whole brain was divided into segments. RESULTS: Every SLE subject exhibited cerebral hypometabolism, in contrast to the normal healthy subjects. Regional analysis revealed a significantly lower ER in the left medial frontal gyrus (p=0.0055) and the right medial frontal gyrus (p=0.0022) in the DSLE group than in the non-DSLE group. CONCLUSION: Hypometabolism in the medial frontal gyrus may be related to major depressive disorder in SLE. Larger studies are needed to clarify this relationship.

OBJECTIVES: Visual hallucinations (VHs) and pain are common non-motor symptoms in Parkinson disease (PD). Although dopaminergic dysfunction has traditionally been considered as the principal cause of these symptoms, the detail mechanisms are still unclear. Conventional treatment for VH, decrease of dopamine agonists, and use of antipsychotic medications often lead to an exacerbation of motor symptoms and excessive sedation. Gabapentin (GPT) is an antiepilepsy drug, which affects the glutamic acid neuron system and the γ-amino butyric acid neuron system. It is also known to have an analgesic effect. Here, we report a case of PD in which GPT improved both VH and pain without any adverse effects. METHODS: This study is a case report. RESULTS: The subject is an 81-year-old Japanese man who was diagnosed with PD at the age of 67 years. His Hoehn and Yahr staging scale was IV. He developed VH of insects and also experienced pain, which is, as he described, caused by these insects invading his body. Despite the general treatments, VH and pain persisted. Moreover, exacerbation of motor symptoms and excessive sedation hindered a further attempt. Gabapentin was administered to ease his pain. After that, not only pain but also VH disappeared without any adverse effects. CONCLUSIONS: The positive outcomes of GPT on VH and pain without any adverse effects may offer us a useful alternative treatment for PD. Further experience and study are needed to prove the efficacy of this agent.
