Abstract

Abstract Background Although numerous studies have been published on the predictors of COVID-19 vaccine hesitancy, some possible predictors remain underexplored. In this study, we explored the associations of unwillingness and indecisiveness regarding COVID-19 vaccination with generalized trust, mental health conditions such as depression and generalized anxiety, and fear of COVID-19. Methods Data of wave 1 (from October 27 till November 6, 2020) and wave 3 (from April 23 till May 6, 2021) of a longitudinal online study conducted in Japan were used for the analyses. Unvaccinated participants were asked at wave 3 about their willingness to be vaccinated, with possible responses of willing, unwilling, or undecided. These three responses were used as the outcome variable, and multinomial logistic regression analyses were conducted with willingness to be vaccinated as the reference group. Explanatory variables included generalized trust, depression, generalized anxiety, and fear of COVID-19 both at wave 1 and 3, and sociodemographic and health-related variables. Results Of the 11,846 valid respondents, 209 (1.8%) answered that they had already been vaccinated against COVID-19, 7089 (59.8%) responded that they were willing to be vaccinated, 3498 (29.5%) responded that they were undecided, and 1053 (8.9%) responded that they were unwilling to be vaccinated. After adjusting for covariates, we found that: (1) participants with lower levels of generalized trust at wave 1 and 3 were more likely to be undecided or unwilling at wave 3; (2) respondents with moderately severe or severe depression at wave 1 and 3 were more likely to be undecided at wave 3; (3) participants with moderate or severe levels of generalized anxiety at wave 3 but not at wave 1 were more likely to be unwilling at wave 3; and (4) respondents with high levels of fear of COVID-19 at wave 1 and 3 were less likely to be undecided and unwilling at wave 3. Conclusions Generalized trust, mental health conditions such as depression and generalized anxiety, and low level of fear of COVID-19 are associated with unwillingness or indecision regarding being vaccinated against COVID-19.

Abstract

Introduction Studies on autism spectrum disorder in recent years have controversially indicated similarities with schizophrenia. Cognitive dysfunction is present in both disorders, and while there is a rich array of interventions for cognitive dysfunction in schizophrenia, there are few such treatments for autism spectrum disorder. In this study, we have investigated a potentially useful approach in autism spectrum disorder by comparing autism spectrum disorder with schizophrenia in regard to the characteristics of cognitive dysfunction and therapeutic response to cognitive remediation therapy. Method We studied seven patients with autism spectrum disorder and eight patients with schizophrenia, using a frontal/executive programme as the intervention. The characteristics of cognitive dysfunction in autism spectrum disorder before frontal/executive programme and the therapeutic response to frontal/executive programme in autism spectrum disorder patients were compared with those in schizophrenia patients, based on evaluation of cognitive function and social function. The changes in cognitive and social function after treatment in each patient group were compared using the Mann–Whitney’s U test. Results The severity of cognitive dysfunction did not differ significantly between autism spectrum disorder and schizophrenia. Frontal/executive programme was effective in autism spectrum disorder, with subjects showing about the same therapeutic response as in schizophrenia. Conclusion Frontal/executive programme appears to be useful for patients with autism spectrum disorder. Furthermore, the similarities in cognitive dysfunction and therapeutic response between autism spectrum disorder and schizophrenia are highly relevant to the recent debate concerning the similarity between these two disease concepts.

Abstract

Background: Behaviors to avoid infection are key to minimizing casualties of the COVID-19 pandemic, as well as to avoid excessive interventions that are less effective. This study aims to identify behavioral patterns associated with SARS-CoV-2 infection in the real world. Methods: A questionnaire-based cross-sectional study was conducted targeting a research panel of NTTCom Online Marketing Solutions Corporation or its affiliates. Data were extracted so that their demographic composition ratios matched the population estimates. Individuals who answered with consistency to have been diagnosed with SARS-CoV-2 at a medical facility were categorized into a SARS-CoV-2 group. Differences in lifestyles were compared using multiple regression and inverse probability weighing. Results: In total 13,277 participants were included, of whom 44 (0.33%) were categorized as the SARS-CoV-2 group. Diagnosis of SARS-CoV-2 was negatively correlated with crowd avoidance, mask wearing, and hand-washing behavior. On the contrary, the diagnosis was positively correlated with some behaviors that appear to be preventive actions against the infection, such as changing clothes frequently, sanitizing belongings, and remote working. Conclusions: It is important to conduct evidence-based intervention on people’s behaviors and to avoid excessive interventions that are less effective, so that people can minimize the indirect harm, such as exhaustion and economic loss.

Abstract

Introduction:Cognitive Remediation Therapy is a new rehabilitation approach that has been created in order to improve cognitive functions such as attention, memory and executive function. We aimed to investigate the effects of one type of Cognitive Remediation Therapy, the Frontal/Executive Program, on cognitive function, social function, and psychiatric symptoms in the chronic phase schizophrenia patients.Methods:Seventeen participants who gave consent were randomly assigned to an intervention group (n=8) or control group (n=9). The intervention consisted of 44 sessions of FEP over a period of approximately six months. Cognitive function, social function, and psychiatric symptoms were evaluated before and after the intervention and before and after a roughly six-month long period for controls. Results: The present study showed improvements in Brief Assessment of Cognition in Schizophrenia-Japanese version composite score and subscales of verbal memory and working memory. Improvements were also observed in overall evaluation in the Schizophrenia Cognition Rating Scale-Japanese version, total Positive and Negative Syndrome Scale score and the Global Assessment of Functioning Scale score. FEP is considered to improve the performance of cognitive function tests and social function tests and psychiatric symptoms tests that are the target of this training.Conclusion:Intervention by Frontal/Executive Program improved cognitive function and psychiatric symptoms in patients with chronic schizophrenia with long disease duration who require large doses of medication. Significant effects of intervention were observed in overall patient, informant and interviewer evaluation in social function test. FEP is a training method the primary means pencil and paper, it is possible to inexpensively implement when compared to the other CRT that uses a computer. There is an advantage that less economic cost.

Abstract

Objective The cognitive features and treatment of autism spectrum disorder have been the subject of much debate in recent years. Therapeutic approaches to date have focused on skills acquisition, support tailored to the characteristics of autism spectrum disorder, and interventions in social cognitive functioning; there have been few reports describing interventions aimed at neurocognitive dysfunction. In this study, we focus on impairment of executive functioning in autism spectrum disorder patients and investigate improvements in executive functioning and their generalization to social functioning. Method The intervention adopted for this study was cognitive remediation therapy using the frontal/executive program. To investigate the effectiveness of frontal/executive program, 15 subjects who consented to participate in the study were randomly assigned to an intervention group or control group. Frontal/executive program was administered to the intervention group for about six months. Both groups were evaluated using the same scales: BACS-J, WCST, and CPT for cognitive assessment; SCoRS-J, GAF, and LASMI for social functioning; and GSE for self-efficacy. Results Both groups had lower scores for cognitive functioning than normal individuals at baseline. After completion of frontal/executive program, the intervention group showed improved performance on BACS-J for overall score, digit sequencing, verbal fluency, and Tower of London tasks. Improvements were also seen on SCoRS-J and LASMI scales of social functioning. Conclusions This was the first study to use frontal/executive program to focus on neurocognitive dysfunction in autism spectrum disorder patients. Frontal/executive program is effective in improving impaired executive functioning in autism spectrum disorder patients and may also lead to improvements in some aspects of social functioning.

Abstract

Concerning medical treatments for adult attention-deficit/hyperactivity disorder (AD/HD), case reports have gradually been accumulating on the efficacy of psychostimulants such as methylphenidate and amphetamine and selective noradrenaline reuptake inhibitors such as atomoxetine. However, patients intolerant to psychostimulants currently have a very limited range of treatments available to them. Here, we report a case of an adult AD/HD patient whose inattention and hyperactivity were remarkably alleviated by milnacipran, a serotonin noradrenaline reuptake inhibitor. Milnacipran has fewer side effects than comparable drugs, and we believe it could be developed into a good curative treatment for AD/HD in the future.

Abstract

Background The long-term outcome of antidepressant-refractory depression is not well known. Therefore, the present study investigated the long-term outcome of 26 antidepressant-refractory patients with depression, whom we had studied and treated in 1995. Methods Before being classified as nonresponse, these patients had been treated adequately with at least two tricyclic or heterocyclic antidepressants (a minimum of the equivalent of 150mg of imipramine for 4 weeks). In 1995, 21 of 26 patients were diagnosed with unipolar depression, while 5 were diagnosed with bipolar depression. Mean follow-up was 5.7 years (range: 1–7 years) and changes in diagnosis, remission and treatment efficacy were evaluated. Results Following the long-term follow-up, 13 patients achieved full remission and demonstrated high social functioning (mean GAF score, 91). A further four depressed patients experienced full remission; however, subsequent recurrence was observed. In total, 17 of 26 patients experienced remission at least once during the long-term follow-up period despite the chronic depressive episodes observed at study entry. Adjuvant treatment with lithium, dopamine receptor agonists or thyroid hormone was effective for promoting full remission. Among the 21 patients initially diagnosed with unipolar depression in 1995, diagnoses were changed to bipolar disorder in 5 cases. Limitations This naturalistic study had a relatively small sample size and treatment was not controlled. Conclusions Long-term follow-up revealed that a substantial proportion of antidepressant-refractory depression is comprised of bipolar disorders. In addition, augmentation therapies are effective for promoting full remission among chronically depressed patients without a risk of serious side effects.

Abstract

Previous investigations have suggested that ghrelin, an endogenous orexigenic peptide, is involved in the pathology of eating disorders. We conducted a study to determine whether any preproghrelin gene polymorphisms are associated with eating disorders. Three hundred thirty-six eating disorder patients, including 131 anorexia nervosa (AN)-restricting types (AN-R), 97 AN-binge eating/purging types (AN-BP) and 108 bulimia nervosa (BN)-purging types (BN-P), and 300 healthy control subjects participated in the study. Genotyping was performed to determine the polymorphisms present, and with this information, linkage disequilibrium (LD) between the markers was analyzed and the distributions of the genotypes, the allele frequencies, and the haplotype frequencies were compared between the groups. The Leu72Met (408 C > A) (rs696217) polymorphism in exon 2 and the 3056 T > C (rs2075356) polymorphism in intron 2 were in LD (D' = 0.902, r2 = 0.454). Both polymorphisms were significantly associated with BN-P (allele-wise: P = 0.0410, odds ratio (OR) = 1.48; P = 0.0035, OR = 1.63, for Leu72Met and 3056 T > C, respectively). In addition, we observed a significant increase in the frequency of the haplotype Met72-3056C in BN-P patients (P = 0.0059, OR = 1.71). Our findings suggest that the Leu72Met (408 C > A) and the 3056 T > C polymorphisms of the preproghrelin gene are associated with susceptibility to BN-P.

Abstract

Objective To examine the relative importance of risk factors associated with depressive symptoms and gender differences in exposure to the risk factors among the elderly persons living in the community. Methods The data came from the Minamifurano-town Aging Study, a community-based sample of non-institutionalized elderly persons aged 65 years or older. Of the 731 eligible subjects, 665 were assessed for four domains of the potential risk factors (demographic characteristics, health and disability, stress, and social networks) and depressive symptoms according to the 30-item Geriatric Depression Scale (GDS). Results The mean overall GDS-score was 10.9 (SD 6.2), 10.2 (SD 6.0) in men and 11.6 (SD 6.4) in women. The stress domain in men and the health and disability domain in women contributed most to the explanation of the variation in the GDS-score. Conclusion ‘Stress’ for men and ‘health and disability status’ for women were important factors associated with depressive symptoms. Future studies should determine whether modification of these factors may prevent depression among the elderly persons living in the community. Copyright © 2005 John Wiley & Sons, Ltd.

Abstract

Background Delirium is an organic psychiatric syndrome characterized by fluctuating consciousness and impaired cognitive functioning. High-potency typical neuroleptics have traditionally been used as first-line drugs in the treatment of delirium. However, these drugs are frequently associated with undesirable adverse events including extrapyramidal symptoms (EPS). The purpose of the present open-label, flexible-dose study was to provide preliminary data on the usefulness and safety of quetiapine for patients with delirium. Method Twelve patients with DSM-IV delirium were treated with flexible doses of open-label quetiapine (mean +/- SD dosage = 44.9 +/- 31.0 mg/day). To evaluate the usefulness and safety of quetiapine, scores from the Delirium Rating Scale, Japanese version, were assessed every day (for 1 outpatient, at least twice per week), and scores from the Mini-Mental State Examination, Japanese version, and the Drug-Induced Extrapyramidal Symptom Scale were assessed at baseline and after remission of delirium. Data were gathered from April to October 2001. Results All patients achieved remission of delirium several days after starting quetiapine (mean +/- SD duration until remission = 4.8 +/- 3.5 days). Quetiapine treatment was well tolerated, and no clinically relevant change in EPS was detected. Conclusion Quetiapine may be a useful alternative to conventional neuroleptics in the treatment of delirium due to its rapid onset and relative lack of adverse events. Further double-blind, placebo-controlled studies are warranted.

Abstract

Background: Recently, a dopamine hypothesis of depression was put forward, and several studies have demonstrated that direct and indirect dopamine agonists have antidepressant effects. Methods: Using Clinical Global Impressions, we evaluated the efficacy of 4-week treatment of pergolide as an antidepressant adjuvant involving 20 unipolar depressed patients who were refractory to standard treatment with antidepressants. Results: One patients (5%) were very much improved, seven (35%) much improved, four (20%) minimally improved, six (30%) no change or worse, and two (10%) not assessed. There was no significant difference in any clinical factors between the pergolide responder and non-responder group. Limitations: This study was a non-blind open trial, and pergolide was added to tricyclic and heterocyclic antidepressants. Conclusion: Pergolide may be useful as an antidepressant adjuvant, suggesting a potential role for dopamine-2 stimulation in the antidepressant response.

This study was undertaken to compare bipolar and unipolar depression on Rorschach testing using the Comprehensive System with reference to healthy Japanese controls.Methods: Patients with bipolar or unipolar depression who had undergone the Rorschach test for routine clinical purposes were followed up naturalistically for a long period. Based on diagnostic confirmation after long-term follow-up, scores on this test for patients with bipolar and unipolar depression were compared with those published elsewhere for healthy Japanese controls.Results: The bipolar depression group showed significantly higher scores or positive findings in five variables of the Rorschach test, ie, WSum6, DR2 > 0, (CF + C) > FC + 2, PureC > 1, and Populars > 7, as assessed using the Comprehensive System, than did the unipolar depression group and healthy controls. These scores did not differ between the unipolar depression and control groups.Conclusion: The results of this study show thought disorder or cognitive slippage and marked laxness in modulating emotion in bipolar depression, indicating the psychopathological characteristics of bipolar disorder.Keywords: bipolar depression, bipolar disorder, Rorschach test, thought disorder, unipolar depression

Abstract

The clinical features, course and outcome of mood disorders in childhood and adolescence are discussed. The most specific symptoms of major depressive disorder in childhood and adolescence are irritability, social withdrawal, and comorbidity. Depression is a chronic and recurrent condition. The course of child onset depression resembles those with conduct disorder much more than those with mood disorders, without an increased risk for recurrence of depression into adult life. On the other hand, adolescent onset depression has a high risk of recurrent mood disorder into adulthood.

Abstract

Recent concerns have been raised regarding whether antidepressants, especially selective serotonin reuptake inhibitors (SSRIs) might increase suicidal tendencies and intense debate-rages over the pros and cons of their use. Although systematic reviews and population-based studies have been conducted, a consensus on this association remains to be established. Subsequently, the concept of so-called 'activation syndrome' associated with antidepressants has been accepted without its adequate verification. In the present report, we present our experience of seven cases considered of having 'activation syndrome' brought on by antidepressants, and examine its clinical relevance to bipolar spectrum disorder (Ghaemi, et al., 2001) both symptomatologically and diagnostically. Five patients, diagnosed as having major depressive disorder according to the diagnostic manual (DSM-IV), met the criteria of bipolar spectrum disorder and suffered from activation syndrome following the administration of SSRIs, mainly paroxetine. Similarly, hypomania developed in all five cases with depression; the diagnostic criteria of a hypomanic episode were not met. In the remaining two patients, who were both diagnosed with bipolar disorder, one showed irritability and insomnia through imipramine use, and the another developed a hypomanic and/or a mixed state after the co-administration of fluvoxamine and trazodone. From the results of our examination, 'bipolarity', which is the pivotal factor of bipolar spectrum, might exist behind the phenomenon recognized as activation syndrome, and be revealed by antidepressant treatment, just like manic switching. Moreover, the various problems encountered in the current practice of treating mood disorders, including unipolar-bipolar dichotomy, manic switching by antidepressants, and narrow criteria for a mixed episode, were pointed out a new through this concept of activation syndrome. Actually, the understanding of activation syndrome clinically leads to the prevention of suicidal behavior and the careful use of antidepressants for bipolar (spectrum) disorder, but we must be prudent when applying this concept, since it has not yet been established.

Abstract

Objective: The aim of this study was to investigate the prevalence of depressive symptoms in children and adolescents in the general Japanese population using a depression self-rating scale and determine whether this prevalence varies according to age, gender, or region. Method: The Birleson Depression Self-Rating Scale for children (DSRS) was used to examine the extent to which depressive tendencies were present among 2,453 elementary and middle-school children (6 to 15 years old) in two cities in Japan. Results: The mean DSRS score was high at 8.75 + 5.66. A significant increase in score was observed with increasing age. There were no significant differences between regions. Using a DSRS cutoff score of 15 points as a risk of depression, the scores of 14.9% of the subjects exceeded the cutoff. Conclusions: As determined using the DSRS, a high proportion of Japanese children and adolescents have depressive tendencies.

Abstract

We report the first known case of anorexia nervosa (AN) with Marchiafava-Bignami Disease (MBD) that responded to high-dose intravenous corticosteroid administration. A 16-year-old Japanese female with AN was diagnosed with MBD after rapid weight loss. During the acute stage, she suffered from a sudden onset of coma. After regaining consciousness, she presented with lack of movement, apathy, labile affect, and poverty of speech. On admission, magnetic resonance imaging showed an area of demyelination in the splenium of the corpus callosum. Positron emission tomography obtained 7 days after admission showed areas of hypoperfusion in the medial temporal lobe and in regions anterior and posterior to the central sulcus.
