Frailty Improvement by Multicomponent Drug, Ninjin'Yoeito, in Mild Cognitive Impairment and Mild Alzheimer's Disease Patients: An Open-Label Exploratory Study (FRAMINGO).

Background: Alzheimer's disease (AD) and dementia have increasingly been conceived of as "complex diseases of aging", determined by multiple, simultaneous, interacting pathophysiological processes. The condition known as frailty is a phenotype of aging and its comprehensive pathophysiology is thought to be closely related to the incidence of mild cognitive impairment (MCI) and the exacerbation of dementia.

Objective: This study aimed to investigate the effect of the multicomponent drug, ninjin'yoeito (NYT), on frailty in MCI and mild AD patients.

Differential onset time of mirtazapine on pruritus and depression in a patient receiving hemodialysis.

A 63-year-old male receiving hemodialysis for renal insufficiency developed severe and widespread pruritus, which was unresponsive to antihistamines and severe depression with insomnia, agitation, and anxiety. The oral administration of 7.5 mg mirtazapine daily alleviated his severe pruritus after 4 days and severe depression after 14 days.

Burnout in Japanese residents and its associations with temperament and character.

Aim: High risk of burnout in healthcare workers has long been recognized. However, there are no methods to predict vulnerability to burnout.

Methods: We examined whether temperament and character are associated with burnout and depressive state in residents by using the Temperament and Character Inventory (TCI).

Exploratory study of factors influencing job-related stress in Japanese psychiatric nurses.

This study explored the factor structure of psychiatric nurses' job-related stress and examined the specificity of the related stressors using the job stressor scale of the Brief Job Stress Questionnaire (BJSQ). The stressor scale of the BJSQ was administered to 296 nurses and assistant nurses. Answers were examined statistically.

Job-related stress in psychiatric nurses in Japan caring for elderly patients with dementia.

Objectives: We investigated the specificity and structures of job-related stress in psychiatric dementia nurses (PDNs) caring for elderly patients with serious behavioral and psychological symptoms of dementia who required substantial assistance with activities of daily living, in order to obtain fundamental knowledge toward providing mental health care for these nurses.

Methods: Subjects were 244 nurses [63 PDNs and 181 other psychiatric nurses (OPNs)]

Results: Analysis of covariance to examine the specificity of job-related stress in PDNs revealed physical workload and work environment to be more significant stressors, and irritability and anxiety to be more significant stress reactions in PDNs than in OPNs. An examination of PDNs' job-related stress structures established in a structural equation model with two stress reactions confirmed as specific outcomes for PDNs revealed a significant positive influence of work environment on irritability; utilization of techniques for anxiety and physical workload influenced both stress reactions.

Effects of cabergoline and rotigotine on tacrine-induced tremulous jaw movements in rats.

Objectives: We examined the effects of two dopamine agonists, cabergoline and rotigotine, on tacrine-induced tremor and c-Fos expression in rats.

Methods: Rats received intraperitoneal injection of cabergoline (0.5, 1.

Differences in job stress experienced by female and male Japanese psychiatric nurses.

In psychiatric nursing, female nurses tend to spend more time building rapport with patients and developing cooperative working relationships with colleagues; they encounter more sexual harassment by patients. In contrast, male nurses respond to aggressive patients and tend to resist physically caring for female patients; they encounter more physical and verbal assault from patients. These gender differences might result in differences in job-related stress.

Intrastriatal grafts of fetal ventral mesencephalon improve allodynia-like withdrawal response to mechanical stimulation in a rat model of Parkinson's disease.

We previously reported that a unilateral 6-hydroxydopamine (6-OHDA) rat model of Parkinson's disease showed allodynia-like withdrawal response to mechanical stimulation of the ipsilateral side of the rat hindpaw. The goal of this study was to investigate the effect of intrastriatal grafts of fetal ventral mesencephalon (VM) on the withdrawal response in 6-OHDA rats. The withdrawal threshold in response to the mechanical stimulation of the rat hindpaw was measured using von Frey filaments.

Weight control in schizophrenic patients through Sakata's Charting of Daily Weight Pattern and its associations with temperament and character.

Aim: This study examined whether daily self-monitoring of weight and monthly interviews with a doctor improved eating habits and led to weight loss, and whether temperament and character traits affect weight change in persons with schizophrenia.

Methods: Participants used Sakata's Charting of Daily Weight Pattern to monitor their weight daily. In addition, Sakata's Eating Behavior Questionnaire was administered to evaluate eating-behavior awareness.

Effect of blonanserin on methamphetamine-induced disruption of latent inhibition and c-Fos expression in rats.

To clarify the psychopharmacological profile of blonanserin, a novel antipsychotic, we examined its effect on the methamphetamine-induced disruption of latent inhibition (LI) and the neural activation related to this effect in rats. To evaluate the LI, we used a conditioned emotional response in which a tone (conditioned stimulus) was paired with a mild foot shock (unconditioned stimulus). This paradigm was presented to rats licking water.

Development of the Psychiatric Nurse Job Stressor Scale (PNJSS).

Aims: The aim of the present study was to develop a tool, the Psychiatric Nurse Job Stressor Scale (PNJSS), for measuring the stress of psychiatric nurses, and to evaluate the reliability and validity of the PNJSS.

Methods: A total of 302 psychiatric nurses completed all the questions in an early version of the PNJSS, which was composed of 63 items and is based on past literature of psychiatric nurses' stress.

Results: A total of 22 items from four factors, 'Psychiatric Nursing Ability', 'Attitude of Patients', 'Attitude Toward Nursing' and 'Communication', were extracted in exploratory factor analysis.

Differential expression of FosB, c-Fos, and Zif268 in forebrain regions after acute or chronic L-DOPA treatment in a rat model of Parkinson's disease.

A study was carried out to examine the effects of acute and chronic L-DOPA treatment on the distribution of the immediate-early gene (IEG) proteins (FosB, c-Fos, and Zif268) in forebrain regions in a unilateral 6-hydroxydopamine (6-OHDA) rat model of Parkinson's disease. During a course of chronic L-DOPA treatment (15 mg/day, 15 days), rats with a 6-OHDA lesion developed abnormal involuntary movements. Compared with the rats in the acute L-DOPA treatment group, those in the chronic treatment group had significantly more FosB-immunopositive cells in the anterior cingulate (Cg) and the dorsolateral caudate-putamen ipsilateral to the lesion and significantly fewer c-Fos-immunopositive cells in the Cg, the nucleus accumbens shell, and the basolateral nucleus of amygdala ipsilateral to the lesion.

Analgesic effect of milnacipran is associated with c-Fos expression in the anterior cingulate cortex in the rat neuropathic pain model.

The objective of the present study was to examine whether milnacipran, a serotonin-noradrenaline reuptake inhibitor, has an analgesic effect in rats with neuropathic pain. In addition, the c-Fos expression was investigated in the supraspinal sites of the brain and in the spinal dorsal horn in association with the nociceptive processing in rats with neuropathic pain produced by chronic constriction injury (CCI) in the sciatic nerve. In the CCI-induced neuropathic rats, behavioral testing for determining the change in the withdrawal threshold to mechanical stimulation and immunohistochemical detection of c-Fos were both performed.

Psychological prenatal stress reduced the number of BrdU immunopositive cells in the dorsal hippocampus without affecting the open field behavior of male and female rats at one month of age.

We examined whether prenatal psychological stress with little physical stress causes changes in the behavior and neurogenesis of the offspring of Sprague-Dawley rats at one month. Dams in the last trimester of gestation were psychologically stressed by placing them in a social communication box and shocking a rat on the other side of a transparent wall. They suffered little physical stress.

Differential expression of Fos and Zif268 in the nigrostriatal system after methamphetamine administration in a rat model of Parkinson's disease.

The goal of this study was to examine the topological specificity of methamphetamine-induced activation of the immediate-early gene proteins, Fos and Zif268, in the nigrostriatal system in a unilateral 6-hydroxydopamine (6-OHDA) rat model of Parkinson's disease with or without intrastriatal grafts of fetal ventral mesencephalon. Methamphetamine (3 mg/kg, i.p.
