Between March 27 and April 11, 2021, 204 self-administered anonymous questionnaires were distributed, and 149 responses were received. Symptoms of depression and anxiety were assessed using the Hospital Anxiety and Depression Scale (HADS). Personality trait was assessed using the Big Five personality traits, and fear of COVID-19 was assessed using the Fear of COVID-19 Scale. We examined associations between HADS depression or anxiety scores with individual background factors, scores of Big Five personality traits, and Fear of COVID-19 Scale.Results: The participants with anxiety had significantly higher scores for neuroticism and for the Fear of COVID-19 Scale. The participants with depression had significantly lower scores for extraversion and higher scores for the Fear of COVID-19 Scale. No individual background factors were significantly associated with HADS depression or anxiety scores.Conclusion: Among family members of staff of a COVID-19 frontline hospital, lower extraversion, higher neuroticism, and fear of COVID-19 were associated with anxiety and depression.

DUP data were obtained from DUM by excluding individuals with nonpsychotic mental illnesses (e.g., mood disorders, neurotic disorders, substance use, epilepsy). Student's t-test was used to compare DUM and DUP, and analysis of variance was conducted to identify associations.Results: Mean DUM significantly differed between PP (0.6 [SD 2.3] years) and SR (4.2 [5.9] years). Mean DUP was also significantly different (0.5 [2.2] years in PP vs. 4.3 [6.7] years in SR). DUM was strongly associated with DUP. The prevalence of the various disorders differed between rural and urban areas. DUM also varied by diagnosis, indicating that DUP is a better index than DUM. However, in some cases DUM can be used, given its strong association with DUP. DUP in PP was almost the same as in developed countries and was about four times longer in SR.Conclusion: DUP in rural areas is much longer than in urban areas in developing countries.

Studies with children or adolescents between the ages 5 and 18 years were included. Of the 2527 records that were identified, nine studies met the full-inclusion criteria.

Meanwhile, there seems to be insufficient evidence for its efficacy in reducing low mood (d = -0.42; 95% CI: -0.84 to 0.01).

This study aimed to evaluate serum oxytocin levels in older adults living in a rural community and their association with cognitive function, anxiety, depressive state, and well-being.Methods: This survey was conducted between November 2016 and September 2017 in Kurokawa-cho, Imari, Saga Prefecture, Japan, among people aged ≥65 years. Blood samples were collected from the participants for serum oxytocin level analysis, which was performed using peptide enzyme immunoassay.

Additionally, nondepressive state/depressive state was classified by the 15-item Geriatric Depression Scale (cut-off 5/6).

This study estimated the proportion of MCI patients with probable ADHD and investigated the factors to identify MCI patients with probable ADHD.Methods: We recruited 36 elderly patients (11 males, 25 females, mean age 72.4 ± 7.6 years) who met the MCI criteria. The MCI patients were classified as those with [MCI/ADHD (+)] and without [MCI/ADHD (-)] probable ADHD, according to the Wender Utah Rating Scale scores. The autism features, inattention, and hyperactivity features during childhood and current periods, estimated intelligence quotient, and demographic data were compared between the groups. Multiple logistic regression analysis was performed to identify factors of MCI/ADHD (+) patients.Results: Nine (25.0%) and 27 patients were added into the MCI/ADHD (+) and MCI/ADHD (-) groups, respectively. The MCI/ADHD (+) group mostly comprised men, those who visited the clinic at a younger age, had more years of schooling, and had strong autism spectrum disorder tendencies. Multiple logistic regression analysis indicated male sex and current hyperactivity as significant predictors of probable ADHD in MCI patients.Conclusion: A quarter of the patients with MCI had probable ADHD. Male sex and hyperactivity at the time of MCI diagnosis might help in predicting probable ADHD in MCI patients. However, these results were obtained from a single-center, small-case study and should be confirmed via longitudinal studies with a large number of cases.","PeriodicalId":74405,"journal":{"name":"PCN reports : psychiatry and clinical neurosciences","volume":" ","pages":"e104"},"PeriodicalIF":0.0,"publicationDate":"2023-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11114295/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42679854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The \"theory of the remission process of schizophrenia\" is a representative example of Nakai's research and theories. The significance of Nakai's theory of the remission process is that it let the world know about the existence of schizophrenia's remission process, which had not been previously recognised. Additionally, Nakai's discovery of the \"critical period\" was significant and his detailed description of the same, which marks the beginning of the remission process, is widely considered to be fundamental. Nakai closely followed common phenomena that appeared accidentally, and he plotted the reactions of the autonomic nervous system, patient's dream content, and drawing content on a chart to show, for the first time, the clear emergence of a \"critical period,\" and demonstrated the crucial role of the remission process. Nakai explained how the process progresses sequentially from the \"critical period\" to the \"early remission period\" and the \"late remission period.\" He identified many specific indicators and discovered a great significance in innovative therapeutic engagement in each of these periods. Nakai's findings are supported by meticulous clinical observations and are free from simplifications that stem from simple theorization. In particular, close observation of the remission process was conducted with full engagement and concern of the therapist, without which, the remission process would not have been visible.","PeriodicalId":74405,"journal":{"name":"PCN reports : psychiatry and clinical neurosciences","volume":" ","pages":"e96"},"PeriodicalIF":0.0,"publicationDate":"2023-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11114428/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48678894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During hospitalization, her cenesthetic hallucinations progressed to include nihilistic delusions. She described cenesthetic hallucinations along with various delusional descriptions, including the belief that various objects, such as spoons, irons, nails, rulers, bins, and coins, were inside her body and that her body was being burned or in danger of exploding. She also claimed an altered sense of her own body, that her body was larger than normal or reversed. Moreover, she reported nihilistic delusions that her face and body did not exist, that her heart was not functioning, and that she was going to die soon or was already dead. She occasionally refused to eat because of the feeling of being dead. Notably, during a severe episode, she claimed that a doctor in front of her was dead. Clozapine was effective in improving her symptoms. Ultimately, the patient regained her sense of being alive and acknowledged that the doctor was alive.Conclusion: We report the case of a patient presenting with nihilistic delusions regarding both self and others, along with prior cenesthetic hallucinations.
