This study surveyed adult web monitor enrollees about the lives of and stress experienced by Japanese children and adolescents during the prolonged coronavirus disease 2019 (COVID-19) pandemic. The survey was conducted on February 10, 2022 (after the sixth wave) and August 19, 2022 (during the seventh wave of the COVID-19 pandemic in Japan), with 231 and 217 survey participants, respectively. The questionnaire was designed so that adults could assess the frequency of exercise, and difficulties experienced by children and adolescents around them. Regarding exercise opportunities, 22% of parents of middle and high school children reported that children’s exercise opportunities “stayed the same” or “increased considerably” in the first survey. Whereas, in the second survey, all parents of middle and high school children reported that children’s exercise opportunities “decreased.” Regarding stress, 17% of parents of adolescents 18 years and older responded that the stress experienced was the “same as before” or “a little less than before” in the first survey, but all of these parents responded “quite a bit” to the same question in the second survey. The findings suggest that the life changes caused by the COVID-19 pandemic may have a significant impact on children and adolescents and may increase stress. The long-term effects of the COVID-19 pandemic on children and adolescents should be further investigated.

Introduction: Adolescents affected by disasters need mental health support because they tend to be at risk of developing psychiatric disorders and stress as grown-ups. However, it is difficult to develop and validate a support system for adolescents affected by disasters because it is unknown when and where disasters occur, and there is inadequate data related to this in Japan. Methods: To address these issues, we present a mental health support system for high school students affected by the Great East Japan Earthquake. We hypothesized that mental health support could be provided by classroom teachers and school nurses, who are familiar with high school students. We investigated the psychological state of the affected high school students for three years after the earthquake, and the students in psychological crises received interventions from their class teachers and school nurses. Results: The intervention resulted in improvements in depression and post-traumatic stress reaction (PTSR). Conclusion: These results suggest that our high school-based intervention is a feasible solution for mental health support for adolescents affected by the disaster.

The retina shares structural and functional similarities with the brain. Furthermore, structural changes in the retina have been observed in patients with schizophrenia spectrum disorders (SSDs). This systematic review and meta-analysis investigated retinal abnormalities and their association with clinical factors for SSD.Studies related to retinal layers in SSD patients were retrieved from PubMed, Scopus, Web of Science, Cochrane Controlled Register of Trials, International Clinical Trials Registry Platform, and PSYNDEX databases from inception to March 31, 2021. We screened and assessed the eligibility of the identified studies. EZR ver.1.54 and the metafor package in R were used for the meta-analysis and a random-effects or fixed-effects model was used to report standardized mean differences (SMDs).Twenty-three studies (2079 eyes of patients and 1571 eyes of controls) were included in the systematic review and meta-analysis. The average peripapillary retinal nerve fiber layer (pRNFL) thickness, average macular thickness (MT), and macular ganglion cell layer-inner plexiform layer (GCL-IPL) thickness were significantly lower in patients than in controls (n = 14, 6, and 3, respectively; SMD = -0.33, -0.49, and -0.43, respectively). Patients also had significantly reduced macular volume (MV) compared to controls (n = 7; SMD = -0.53). The optic cup volume (OCV) was significantly larger in patients than in controls (n = 3; SMD = 0.28). The meta-regression analysis indicated an association between several clinical factors, such as duration of illness and the effect size of the pRNFL, macular GCL-IPL, MT, and MV.Thinning of the pRNFL, macular GCL-IPL, MT, and MV and enlargement of the OCV in SSD were observed. Retinal abnormalities may be applicable as state/trait markers in SSDs. The accumulated evidence was mainly cross-sectional and requires verification by longitudinal studies to characterize the relationship between OCT findings and clinical factors.

Coronavirus disease 2019 (COVID-19) is causing disruptions in the global social system. Japanese children and adolescents have had their schools closed, government-mandated activity restrictions imposed, and interactions outside the home reduced. These restrictions can have a considerable psychological impact on children and adolescents. This review aims to describe the impacts of COVID-19 pandemic on physical activity and psychological status of this population. The review was conducted by searching PubMed for information on the impact of COVID-19-related activity restrictions on children and adolescents. The search identified 11 articles, three of which contained data on anxiety and psychological problems due to physical inactivity. Next, a PubMed search was conducted about physical activity and psychological status in children and adolescents under psychological stress. The search identified 368 articles, 28 of which were included in the review. For children, data that revealed a correlation between physical activity and psychological health and sedentary time leading to mood disorders were included. For adolescents, there were nine studies that reported a correlation between physical activity and psychological health and four studies that reported no correlation between physical activity and psychological health. Of the studies that reported a correlation, seven reported that physical activity improves psychological health. The impact of psychologically stressful situations such as COVID-19 on children and adolescents has been experienced worldwide. Physical activity has been correlated with psychological health, and it may improve psychological status; physical activity should be recommended to better support the psychological health of children and adolescents under the influence of COVID-19.

Recent evidence has indicated that the disruption of oligodendrocytes may be involved in the pathogenesis of depression. Genetic factors are likely to affect trait factors, such as characteristics, rather than state factors, such as depressive symptoms. Previously, a negative self-schema had been proposed as the major characteristic of constructing trait factors underlying susceptibility to depression. Thus, the association between a negative self-schema and the functional single nucleotide polymorphism (SNP) rs1059004 in the OLIG2 gene, which influences OLIG2 gene expression, white matter integrity, and cerebral blood flow, was evaluated. A total of 546 healthy subjects were subjected to genotype and psychological evaluation using the Beck Depression Inventory-II (BDI-II) and the Brief Core Schema Scale (BCSS). The rs1059004 SNP was found to be associated with the self-schema subscales of the BCSS and scores on the BDI-II in an allele dose-dependent manner, and to have a predictive impact on depressive symptoms via a negative-self schema. The results suggest the involvement of a genetic factor regulating oligodendrocyte function in generating a negative-self schema as a trait factor underlying susceptibility to depression.

Previous studies have indicated associations between several OLIG2 gene single-nucleotide polymorphisms (SNPs) and susceptibility to schizophrenia among Caucasians. Consistent with these findings, postmortem brain and diffusion tensor imaging studies have indicated that the schizophrenia-risk-associated allele (A) in the OLIG2 SNP rs1059004 predicts lower OLIG2 gene expression in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia patients and reduced white matter (WM) integrity of the corona radiata in normal brains among Caucasians. In an effort to replicate the association between this variant and WM integrity among healthy Japanese, we found that the number of A alleles was positively correlated with WM integrity in some fiber tracts, including the right posterior limb of the internal capsule, and with mean blood flow in a widespread area, including the inferior frontal operculum, orbital area, and triangular gyrus. Because the A allele affected WM integrity in opposite directions in Japanese and Caucasians, we investigated a possible association between the OLIG2 gene SNPs and the expression level of OLIG2 transcripts in postmortem DLPFCs. We evaluated rs1059004 and additional SNPs in the 5′ upstream and 3′ downstream regions of rs1059004 to cover the broader region of the OLIG2 gene. The 2 SNPs (rs1059004 and rs9653711) had opposite effects on OLIG2 gene expression in the DLPFC in Japanese and Caucasians. These findings suggest ethnicity-dependent opposite effects of OLIG2 gene SNPs on WM integrity and OLIG2 gene expression in the brain, which may partially explain the failures in replicating associations between genetic variants and psychiatric phenotypes among ethnicities.

Aim Resilience, the ability to cope with disasters and significant life adversity, is an important factor to consider when studying the mental health of populations affected by a disaster. Although high school students in a community affected by a disaster should have specific characteristics of resilience, little has been reported on the issue. This study was designed to provide initial data regarding characteristics of the resilience of high school students affected by a catastrophe. Methods A total of 760 high school students in Natori City, which was devastated by the Great East Japan Earthquake in 2011, were profiled, and a 3-year longitudinal study was conducted with 254 students who had entered the school in 2012. Resilience was evaluated with the 10-item Connor-Davidson Resilience Scale. The Quick Inventory of Depressive Symptomatology-Japanese version, the Zung Self-Rating Anxiety Scale, and the Impact of Event Scale-Revised were also administered to assess the students' mental health. Results Among the students who entered the high school in 2012, 28.6% showed high resilience, and the proportion increased to 42.9% in 2013 and 46.6% in 2014. The Quick Inventory of Depressive Symptomatology-Japanese version and Impact of Event Scale-Revised scores decreased significantly over the 3-year study period, but there were no significant differences in the Zung Self-Rating Anxiety Scale scores over time. Conclusion This initial study profiling the characteristics of resilience among adolescents suggests that resilience is a highly changeable component of mental health among people who have faced adversity. Resilience can be a useful indicator of recovery from adversity and a target of interventions for improving mental health conditions.

How natural disasters affect the psychological state of adolescents has not been well studied. Thus, we examined the effect of a natural disaster on high-school-aged youth and considered the most effective forms of support following such a disaster. We examined students from two high schools that were near the epicenter of the 9.0-magnitude Great East Japan Earthquake, which struck the Tohoku coastal area on March 11, 2011, causing severe damage to the region. The questionnaires measuring depression, anxiety, and post-traumatic stress reaction (PTSR) was administered to the students 3 times between July 2012 and August 2014; students who scored above the cut-off values of these measures were considered high-risk students. School teachers, nurses, and counselors provided a school-based intervention for all high-risk students identified in the survey. Data were analyzed using the Kruskal-Wallis H-test. Survey data revealed that 860 of the 1,432 (55.9%) high school students were at high risk of psychological trauma in 2012. This rate did not change substantially in the following 2 years, reaching 1,059 of 1,488 (69.1%) in 2013, and 949 of 1,430 (62.7%) in 2014. Depression and PTSR scores were significantly lower after the intervention (for 2nd and 3rd grade students in 2013 and 2014) compared to before (for the initial 2012 survey). However, there were no significant differences between the 1st grade students for all three years. Thus, school-based interventions involving psychological testing and interviews might reduce the rates of depression and PTSR in high school students.

Objective: To study the coping pattern of a mother of a child with multiple congenital anomalies (MCAs) based on interview data. Methods: The mother of a child born at Tohoku University Hospital, Japan, who was diagnosed with MCAs at 3 days of age and subsequently underwent surgery at 7 months, was asked to be interviewed. She answered semi structured interviews at the hospital when the child was two years old and again when the child was five years old. Psychological assessment with the State-Trait Anxiety Inventory (STAI) and the Self-rating Depression Scale (SDS) was conducted before each interview. Results: Psychological assessment showed that the mother had high levels of anxiety and depression when the child was two and when the child was five years old. The interview data showed that when the mother first learned that her baby had MCAs, her initial reaction was (1) shock. She then felt (2) Absent-minded. (3) Responsibility to take care of her child. (4) Depression, (5) Defense against acceptance of child’s disease as it is. The mother had this sequence of thoughts and emotions between the times of diagnosis of MCAs up through the time of surgery. In the first stage of coping, the mother showed defense against learning as much as possible about her child’s disease and MCAs. In the second stage of coping, the mother reported (when the child was five years old) that she felt that she had some control over her child’s situation. The mother started to accept her child’s disease as she as possible and learned what would be happened to her child. Conclusion: The mother of the child with MCAs was in a severe psychological condition over at least five years since diagnosis. In order to alleviate the psychological stress on mothers of a child with MCAs or other congenital disease, it is useful to educate the mother so that she can understand her child’s disease. However, it is difficult for parents without medical knowledge to understand a complicated disease such as MCAs. Providers need more training to educate parents with MCAs.

Few studies have assessed physical and psychological status in long-term survivors of childhood solid tumors in Japan. For children with such diseases diagnosed and treated in our hospital, our purpose was to clarify the physical and psychological status of long-term survivors and their parents. Subjects were 56 patients who were diagnosed at our institution as having a childhood malignant solid tumor between 1982 and 2005 and had been alive for at least 5 years after treatment. Surveys were sent and returned by mail. Of the 56 patients surveyed, 32 responded. The current health condition and psychosocial status of survivors were evaluated as good by their parents. However, psychological tests revealed psychosocial problems in 28.1% of the children. Severe posttraumatic stress associated with the child’s disease and its treatment was present in 15.6% of the parents. Physical status of long-term survivors of childhood malignant solid tumors was good in general. However, psychological tests revealed psychosocial problems in some of the children and posttraumatic stress in the parents. Considering the diversity of both the diseases and their clinical course, a qualitative study is warranted for further analysis.

Schizophrenia is a serious psychiatric disorder that develops mainly in young adults. Electroconvulsive therapy (ECT) is known to be effective and safe in patients with schizophrenia with acute psychotic exacerbation. Because of the shortage of systematic studies, we conducted a prospective naturalistic study to examine the short-term effects of acute ECT and its safety in young adults with medically intractable first-episode schizophrenia. Subjects were seven consecutive patients, 15-35 years of age, with first-episode schizophrenia or schizophreniform disorder (Diagnostic and Statistical Manual of Mental Disorders, 4th edition; DSM-IV), who had failed to respond to neuroleptics. The seven patients were treated with a first course of ECT, and their clinical symptoms were evaluated on the basis of the Brief Psychiatric Rating Scale (BPRS) (18 items, rated 0-6) and Global Assessment of Functioning (GAF) Scale. The GAF Scale is presented in DSM-IV as a means of assessing global functioning of a psychiatric patient. Scores range from 1-100; the higher GAF score indicates the higher global functioning. Adverse effects resulting from acute ECT were also evaluated. The total BPRS score 1 week after the final session improved significantly compared to the total pre-ECT BPRS score. The GAF score also improved significantly compared to the pre-ECT GAF score. There were no adverse effects during the acute ECT course, except for mild delirium. We conclude that ECT may be an effective and safe treatment option for young adults with intractable first-episode schizophrenia.

The purpose of this study was to investigate factors associated with the psychological impact of the Great East Japan Earthquake on high school students 1 year and 4 months after the disaster, and clarify support needs of the students. In the outreach program for students of three high schools in coastal areas of southern Miyagi Prefecture, Japan, 1,973 students were surveyed after obtaining informed consent for participation. Questionnaires included: the Quick Inventory of Depressive Symptomatology (QIDS-J), Self-rating Anxiety Scale (SAS), Impact of Event Scale-revised (IES-R), and Connor-Davidson Resilience Scale (CD-RISC10). All scores were compared using SPSS 20.0 J between school grades, locations of the schools, and extent of damage due to the Great East Japan Earthquake. Our analysis showed a significant positive correlation between school grades and the level of anxiety. PTSR scores, but not anxiety nor depressive scores, of students whose lives have suffered extensive damage were significantly higher than those of students who have not. Students of high schools which have suffered extensive damage and use temporary buildings showed significantly higher levels of depression and anxiety, and significantly lower resilience, compared to students of high schools which were not damaged. Although previous findings demonstrated that younger children have a higher risk of being influenced by disasters, symptoms related to PTSR and depression were found frequently in the high school students as well. Among the high school students, our analysis showed a positive correlation between the level of anxiety and school grades, probably because the disaster has affected an influential and pivotal point in their lives.
