RESUMO
OBJECTIVES: The aim of this study was to predict increased alcohol and tobacco use in Fukushima nuclear power plant (NPP) workers 3 years after a nuclear disaster. METHODS: Surveys were conducted in two postdisaster waves (Wave 1: 2 to 3 months; Wave 2: 32 months). Adjusted risk ratio (aRR) was computed to assess the covariates of increased alcohol and tobacco use in Wave 2. RESULTS: Increased alcohol use was associated with age of 29 years or less [aRR (95% confidence interval (95% CI): 1.26 (1.01 to 1.57)], major property loss [1.25 (95% CI 1.02 to 1.55)], and high posttraumatic stress responses (PTSRs) [1.34 (95% CI 1.08 to 1.67)] in Wave 1. Increased tobacco use was associated with age of 29 years or less [1.46 (95% CI 1.12 to 1.90)] and high PTSR [1.62 (95% CI 1.25 to 2.10)] in Wave 1 (Pâ<â0.05). CONCLUSION: The workers' increased alcohol and tobacco use were predicted by major property loss (alcohol), age of 29 years or less, and high PTSR (alcohol/tobacco) in Wave 1.

OBJECTIVE: The 2011 Fukushima Daiichi nuclear accident was the worst nuclear disaster since Chernobyl. The Daiichi workers faced multiple stressors (workplace trauma, victim experiences, and public criticism deriving from their company's post-disaster management). Literatures suggest the importance of workplace interpersonal support (WIS) in enhancing psychological health among disaster workers. We sought to elucidate the role of their demographics, disaster-related experiences, and post-traumatic stress symptoms on perceived WIS. METHODS: We analyzed self-report questionnaires of 885 workers 2-3 months post-disaster. We used sociodemographic and disaster exposure-related variables and post-traumatic stress symptoms (measured by the Impact of Event Scale-Revised) as independent variables. We asked whether WIS from colleagues, supervisors, or subordinates was perceived as helpful, and used yes or no responses as a dependent variable. Logistic regression analyses were performed to assess correlates of WIS. RESULTS: Of the participants, one-third (34.7%) reported WIS. WIS was associated with younger age (20-28 years [vs 49-], adjusted odds ratio [aOR]: 3.25, 95% CI: 1.99-5.32), supervisory work status (aOR: 2.30, 95% CI: 1.35-3.92), and discrimination or slur experience (aOR: 1.65, 95% CI: 1.08-2.53). CONCLUSIONS: Educational programs focusing on WIS might be beneficial to promote psychological well-being among nuclear disaster workers, especially younger workers, supervisors, and workers with discrimination experiences.

OBJECTIVE: Disaster relief workers are potentially exposed to severe stressors on the job, resulting in a variety of psychological responses. This study aims to clarify the psychological effects of disaster relief activities on Japan Ground Self-Defense Force (JGSDF) personnel following the 2011 Great East Japan Earthquake. METHOD: A self-report questionnaire was administered to 606 JGSDF personnel one month after completing the disaster relief mission. Posttraumatic stress responses and general psychological distress were assessed using the Impact of Event Scale-Revised (IES-R) and the K10 scales. Associations between outcome variables and independent variables (age, gender, military rank, length of deployment, and exposure to dead bodies) were measured with univariate analyses and subsequent multiple logistic regression analyses. RESULTS: The mean (± SD) IES-R score was 6.2 (± 8.1), and the mean K10 score was 12.8 (± 4.4). In the univariate analyses, exposure to dead bodies and age were identified as significant factors for IES-R and K10 scores, (p < 0.01). However, the multiple logistic regression analyses did not reveal any significant factors although body handlers' exposure approached significance for IES-R. CONCLUSIONS: The subjects reported very low psychological responses despite the severe nature of their disaster relief activities. Several factors may account for the low levels of psychological distress and posttraumatic symptoms observed in this study.

BACKGROUND: The 2011 Fukushima Daiichi Nuclear Power Plant accident was the worst nuclear disaster since Chernobyl. The nearby Daini plant also experienced substantial damage but remained intact. Workers for the both plants experienced multiple stressors as disaster victims and workers, as well as the criticism from the public due to their company's post-disaster management. Little is known about the psychological pathway mechanism from nuclear disaster exposures, distress during and immediately after the event (peritraumatic distress; PD), to posttraumatic stress responses (PTSR). METHODS: A self-report questionnaire was administered to 1,411 plant employees (Daiichi, nâ=â831; Daini, nâ=â580) 2-3 months post-disaster (total response rate: 80.2%). The socio-demographic characteristics and disaster-related experiences were assessed as independent variables. PD and PTSR were measured by the Japanese versions of Peritraumatic Distress Inventory and the Impact of Event Scale-Revised, respectively. The analysis was conducted separately for the two groups. Bivariate regression analyses were performed to assess the relationships between independent variables, PD, and PTSR. Significant variables were subsequently entered in the multiple regression analyses to explore the pathway mechanism for development of PTSR. RESULTS: For both groups, PTSR highly associated with PD (Daiichi: adjusted ß, 0.66; p<0.001; vs. Daini: adjusted ß, 0.67; p<0.001). PTSR also associated with discrimination/slurs experience (Daiichi: 0.11; p<0.001; vs. Daini, 0.09; pâ=â0.005) and presence of preexisting illness(es) (Daiichi: 0.07; pâ=â0.005; vs. Daini: 0.15; p<.0001). Other disaster-related variables were likely to be associated with PD than PTSR. CONCLUSION: Among the Fukushima nuclear plant workers, disaster exposures associated with PD. PTSR was highly affected by PD along with discrimination/slurs experience.

We propose the possibility of 5-hydroxytryptamine (5-HT)1A receptor involvement in mild serotonin toxicity. A 64-year-old woman who experienced hallucinations was treated with perospirone (8 mg/day). She also complained of depressed mood and was prescribed paroxetine (10 mg/day). She exhibited finger tremors, sweating, coarse shivering, hyperactive knee jerks, vomiting, diarrhea, tachycardia, and psychomotor agitation. After the discontinuation of paroxetine and perospirone, the symptoms disappeared. Another 81-year-old woman, who experienced delusions, was treated with perospirone (8 mg/day). Depressive symptoms appeared and paroxetine (10 mg/day) was added. She exhibited tachycardia, finger tremors, anxiety, agitation, and hyperactive knee jerks. The symptoms disappeared after the cessation of paroxetine and perospirone. Recently, the effectiveness of coadministrating 5-HT1A agonistic psychotropics with selective serotonin reuptake inhibitors (SSRIs) has been reported, and SSRIs with 5-HT1A agonistic activity have been newly approved in the treatment of depression. Perospirone is a serotonin-dopamine antagonist and agonistic on the 5-HT1A receptors. Animal studies have indicated that mild serotonin excess induces low body temperature through 5-HT1A, whereas severe serotonin excess induces high body temperature through 5-HT2A activation. Therefore, it could be hypothesized that mild serotonin excess induces side effects through 5-HT1A, and severe serotonin excess induces lethal side effects with hyperthermia through 5-HT2A. Serotonin toxicity via a low dose of paroxetine that is coadministered with perospirone, which acts agonistically on the 5-HT1A receptor and antagonistically on the 5-HT2A receptor, clearly indicated 5-HT1A receptor involvement in mild serotonin toxicity. Careful measures should be adopted to avoid serotonin toxicity following the combined use of SSRIs and 5-HT1A agonists.
RESUMO
The putative antidepressive mechanisms of a series of electroconvulsive seizures (ECS) are the following: 1) downregulation of monoaminergic receptor expression in several brain regions, 2) upregulation of the expression of brain-derived neurotrophic factor (BDNF), and 3) increased neurogenesis in the hippocampus. In this study, we used Western blot techniques to present another mechanism in which ECS enhances the autophagy signaling that is involved in the machinery related to synaptic and neural plasticity. Antibodies for conjugated Atg5-Atg12 (58kD) and cleaved light chain protein 3-II (LC3-II; 14 kD) were used to detect autophagy signals. An antibody for cleaved caspase-3 (17 kD) was used to detect alterations in apoptotic signals. Mature BDNF (14kD) expression in the hippocampus was evaluated in order to qualify the effectiveness of the ECS or stress-loading treatment. While significantly increased autophagy signals and no increases in apoptotic signals were detected in the ECS-treated rat hippocampus, the reverse (increased apoptotic signals and no altered autophagy signals) was observed in stressed rat hippocampus. No neuronal cell loss but new mossy fiber sprouting has been reported to accompany multiple ECS treatments, and recent studies have revealed that autophagy processes regulate the number of specific neurotransmitter receptors and the plasticity of synaptic components. The present study illustrated the neuroplastic and neurotrophic profiles of ECS and the neurotoxic impact of severe stress loading on hippocampal regions. This is the first report to demonstrate increased autophagy signals in ECS-treated rat hippocampus and no alterations in autophagy signals in stress-loaded rat hippocampus.

Pharmacological treatment strategies for bipolar disorder (BD) remain elusive due to a dearth of evidence. This paper delineates BD treatment guidelines recently published by the Japanese Society of Mood Disorders, and also presents clinical experiences of long-term medication among 22 BD patients. With the evidence-based guidelines and real-world experiences taken into account, the author proposed an algorithm of medical treatment for bipolar and bipolar spectrum disorders.

AIM: We examined the relationship between return to work (RTW) from sick leave (SL) and personality traits in workers with major depressive disorder (MDD). METHODS: Eighty-eight Japanese individuals with ≥2 weeks of SL episode and with ≥2 months of pharmacotherapy history were assessed. Measurements included Mini-International Neuropsychiatric Interview (MINI), Hamilton Rating Scale for Depression (HAM-D), Neuroticism, and Interpersonal Sensitivity Measure (IPSM). Multivariate analyses were conducted to clarify the association between personality traits and RTW status. In order to minimize the state effect of depressive symptoms to personality traits, we performed an additional analysis among a subgroup of subjects in remission (HAM-D ≤7). RESULTS: Thirty-seven subjects (42.0%) had returned to work. Among whole subjects, factors associated with RTW status were: shorter SL duration in the past 5 years, longer treatment duration of the recent major depressive episode, HAM-D ≤7, and IPSM ≤94. In the subgroup of remission subjects (n=53), factors associated with RTW status were: IPSM ≤94, no comorbid current anxiety disorder, and shorter SL duration in the past 5 years. CONCLUSIONS: Low interpersonal sensitivity, along with depression remission, was associated with post-SL RTW status among workers with MDD.

OBJECTIVE: Wolff-Parkinson-White (WPW) syndrome is characterized by premature ventricular excitation due to the presence of an abnormal accessory pathway. Electrocardiography (ECG) of patients with WPW syndrome portrays a short PR interval and a wide QRS interval with a delta wave. METHODS: Herein, we report the case of a patient with schizophrenia who developed a wide QRS interval with a delta wave immediately following electroconvulsive therapy (ECT). RESULTS: Initially, the delta wave disappeared within 2 days after ECT. However, the duration of the delta wave increased exponentially to 4 months when ECT was repeated. CONCLUSION: Although the patient's cardiocirculatory dynamics remained normal, we continued to monitor her ECG until the delta wave disappeared because WPW syndrome can lead to serious arrhythmia.

Accumulating clinical knowledge indicates that electroconvulsive therapy (ECT) can be used in patients with stable and small brain tumors without any sign of increasing intracranial pressure as long as the risks have been appropriately evaluated. However, there are no clear and detailed clinical guidelines for the application of ECT in patients with brain tumors. Severe complications are described in cases reported before 1980 when the definitive diagnosis of brain tumor before ECT was difficult. We reviewed 13 cases from the literature from the 1980s or later in which ECT was administered to psychiatric patients with a prior diagnosis of meningiomas, a very common type of tumor, before ECT. All cases responded to ECT. Among the cases reviewed, the largest meningioma was 3 x 3 cm. Minor complications such as headache and transient confusion were reported in 5 of 13 cases; however, no severe complications were observed. Accurate identification and careful evaluation of meningioma by routine neuroimaging and other advanced medical techniques surrounding the use of ECT have contributed to the decrease in severe complications.

Following the March 11, 2011 Great Japan East Earthquake and the Fukushima Daiichi Nuclear Power Plant accident, disaster workers have been working day and night for recovery efforts. A large part of disaster workers, i.e., Self-Defense Force, police, fire department, and coast guard personnel, were highly acknowledged by the Japanese public for searching nearly 19,000 dead or missing victims. This recognition will be beneficial for their psychological recovery. On the other hand, dentists and government employees also took a large role in these mortuary missions, but their work was hardly known to the people. Furthermore, local government employees became victims of public criticisms. Similar phenomenon has been seen among Fukushima nuclear plant workers. These workers have experienced a whole array of traumatic stress, including near-death work experiences, irradiation fear, loss of their properties and their loved ones. The electric company has been blamed by the public for their disaster responses, so the public portrays these employees as disaster perpetrators. However, this trend is leading to serious discriminations and harassments, and adversely affecting their mental health. We all hope the recovery efforts to complete as soon as possible. However, when people criticize these workers, their burden of psychological trauma will continue to grow, and their recovery process will be impeded. It is crucial for the society to recognize these hard-working people and to show appreciation and support for their dedications.

Fukushima Daiichi Nuclear Power Plants suffered serious damage by the Great East Japan Earthquake and Tsunami. The employees of the plant worked very hard to stabilize the nuclear reactor and to prevent any secondary accidents. They were in one of the most severe situations in this disaster, but they were the people who hesitated most to request help for themselves. We started visiting the Fukushima Daini Plant office that was used as the frontline base for Daiichi Plant workers since July, 2011. These visits were held once or twice a month and we offered mental health support to the employees. We have completed interview with the total number of 339 plant workers by April, 2012. We offered several ways of mental support including clinical treatment, continuous counseling, or one time advice, depending on mental condition of each interviewee. Complexity of huge disaster and individuality of suffering from it were discussed in this article. Like local residents, many plant workers also experienced death/missing of family, loss of housing, refuge life, and dispersion of family. Furthermore, they have been suffering from various kinds of criticism and slander against Tokyo Electric Power Company. Many workers, even though they were not in management positions, seemed to have guilty conscience and sense of responsibility that forced them to stay in the risky working site. We could find some struggling coexistence of sense of guilt (as a causer of disaster) and sense of victim in their mind. It was suggested that continuous effort to listen and pay attention to their talk is important in order to support their mission to stabilize the power plant and to prevent them from over-stress and burnout.

Compared to the well-known anti-ulcerogenic properties of tricyclic antidepressants, the impact of selective serotonin reuptake inhibitors (SSRIs) on gastric mucosa is less clear. Human clinical trials have shown that SSRIs and non-steroidal anti-inflammatory drugs (NSAIDs) act synergistically and promote stomach ulcer formation and upper gastrointestinal tract bleeding. Acute SSRI treatment confers an additional risk for the formation of NSAID-induced gastric ulcers through increase in gastric acid secretion. Stress, which is often experienced by depressed patients, also deteriorates the gastric environment. Thus the potential for exacerbating stress-induced gastric lesions must be considered before prescribing SSRIs. Therefore, we evaluated the effects of paroxetine by using a water-immersion stress-induced stomach ulcer model of mice, by examining single vs. repeated paroxetine treatments for 8 and 22 days before stress induction. Repeated administration of paroxetine significantly decreased the area of stress-induced stomach lesions. Although stress significantly increased the serum corticosterone concentrations, the levels were not affected by the 8-day paroxetine treatment. We confirmed the anxiolytic and antidepressive effects of 8-day paroxetine treatment at 1 and 5 days after stress induction by using the elevated plus-maze and tail-suspension tests. We concluded that repeated paroxetine treatment significantly attenuates the stress-induced ulcerogenic process in the stomach.
