Aim: The duration of untreated psychosis (DUP) is an important prognostic indicator of schizophrenia. We explored the effects of patient personality and family relationships on delayed schizophrenia treatment., Methods: We prospectively included data from 169 patients diagnosed with first-episode schizophrenia. Personality traits were investigated using the Big Five Inventory (BFI-10) and family relationship was assessed employing the Family Adaptability and Cohesion Evaluation Scale-III (FACES-III). We explored patient clinical characteristics using the Positive and Negative Syndrome Scale (PANSS) and the Social and Occupational Functioning Scale (SOFAS). The DUP was defined as the time between the first appearance of psychotic symptoms and commencement of adequate antipsychotic treatment. Subjects were divided into two groups by the 3-month median DUP cutoff., Results: The average and median DUPs were 12 and 3 months, respectively. A longer DUP was associated with older age, a higher PANSS score, and a lower SOFAS score. The frequency of suicide attempts tended to be higher in the delayed treatment group (P = .055). The delayed treatment group scored significantly higher in conscientiousness factor of the BFI-10 and scored significantly lower family cohesion and adaptability factors of the FACES-III. Logistic regression showed that a longer DUP was significantly associated with higher-level conscientiousness on the BFI-10 and poorer family cohesion on the FACES-III., Conclusion: Treatment delay was associated with reduced family cohesion and higher patient conscientiousness, suggesting that the family plays a crucial role in terms of patient access to mental health services when early psychotic symptoms appear., (© 2020 John Wiley & Sons Australia, Ltd.)

Aim: This study investigated the clinical characteristics and psychosocial factors associated with depression in patients with early psychosis according to stage of illness., Methods: The present study includes patients who fulfil the DSM-5 criteria for schizophrenia spectrum and other psychotic disorders. Patients were divided into two groups according to illness stage (the acute stage of first-episode psychosis and stabilization phase of recent-onset psychosis). Clinically meaningful depression was defined as moderate or severe on the depression dimension of the Clinician-Rated Dimensions of Psychosis Symptom Severity scale in the DSM-5., Results: In total, 340 (207 first-episode and 133 recent-onset) patients were recruited in this study. Patients with comorbid depression were characterized by frequent suicidal ideation, a past suicide attempt, and lower scores on the Subjective Well-being Under Neuroleptics and Brief Resilience Scale in both groups. Long duration of untreated psychosis and higher scores on the Early Trauma Inventory Self Report were associated with depression in the acute stage of first-episode psychosis. In the stabilization phase of recent-onset psychosis group, a monthly income and scores for sexual desire and on the Family Adaptability and Cohesion Evaluation Scale-III were significantly lower in patients with depression than in those without depression., Conclusion: Comorbid depression was associated with high suicidality, lower quality of life and poor resilience in patients with first-episode and recent-onset psychosis. Depression was associated with factors that had been present before the initiation of treatment in patients with first-episode psychosis and with environmental factors in those in the stabilization phase., (© 2019 John Wiley & Sons Australia, Ltd.)

Introduction: The present study aimed to examine smartphone use in young patients with schizophrenia and to explore factors that may affect the severity of problematic smartphone use., Methods: A total of 148 schizophrenia patients aged 18 to 35 years completed self-administered questionnaires exploring sociodemographic characteristics; Smartphone Addiction Scale (SAS), the Big Five Inventory-10 (BFI-10), the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale (PSS), and the Rosenberg Self-Esteem Scale (RSES). All were also assessed using the Clinician-Rated Dimensions of Psychosis Symptom Severity (CRDPSS) Scale and the Personal and Social Performance (PSP) Scale., Results: The mean subject age was 27.5 ± 4.5 years. No significant differences in the SAS scores occurred between gender, jobs, and level of education. The Pearson r-correlation test showed that the SAS scores were significantly positively correlated with HADS anxiety, PSS, and BFI-10 neuroticism scores; it was negatively correlated with RSES, BFI-10 agreeableness, and conscientiousness scores. In the stepwise linear regression analysis, the severity of PSU was significantly associated with both high anxiety and low agreeableness., Discussion: Our results suggest that specific groups of patients with schizophrenia may require special care to prevent problematic smartphone use., (© 2019 John Wiley & Sons Australia, Ltd.)

Iron deficiency may alter dopaminergic transmission in the brain. This study investigated whether iron metabolism is associated with negative symptoms in patients with first-episode psychosis. The study enrolled 121 patients with first-episode schizophrenia spectrum disorder, whose duration of treatment was 2 months or less. Negative symptoms were measured using the Positive and Negative Syndrome Scale (PANSS) and Clinician-Rated Dimensions of Psychosis Symptom Severity (Dimensional) scale of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Prominent negative symptoms were defined as moderate or severe negative symptoms on the Dimensional scale of the DSM-5. Iron deficiency was defined as a serum ferritin ≤ 20 ng/mL. Patients with iron deficiency were significantly more likely to have prominent negative symptoms (45.2 vs. 22.2%; p = 0.014) and a higher PANSS negative symptoms score ( p = 0.046) than those with normal ferritin levels. Patients with prominent negative symptoms had significantly lower ferritin levels ( p = 0.025). The significance of these results remained after controlling for the duration of illness and other confounding variables. Our finding of an independent association between iron deficiency and negative symptoms in patients at the very early stage of illness implies that iron dysregulation has an effect on negative symptoms in patients with schizophrenia. The possibility of therapeutic intervention with iron should be further investigated.

Introduction: Internet use is already high and increasing rapidly among people with psychotic disorders, but there have been few studies on problematic Internet use (PIU) among patients with schizophrenia spectrum disorders. This study aimed to measure the prevalence of PIU and identify the factors associated with PIU among patients with schizophrenia spectrum disorders., Methods: A cross-sectional survey was performed that included 368 outpatients with schizophrenia spectrum disorders: 317 with schizophrenia, 22 with schizoaffective disorder, 9 with schizophreniform disorder, and 20 with other schizophrenia spectrum and psychotic disorders. The severity of psychotic symptoms and levels of personal and social functioning were assessed by the Clinician-rated Dimensions of Psychosis Symptom Severity (CRDPSS) scale and the Personal and Social Performance (PSP) scale, respectively. PIU was evaluated using Young's Internet Addiction Test (IAT). Additionally, the Hospital Anxiety and Depression Scale (HADS), Perceived Stress Scale (PSS), Rosenberg Selfesteem Scale (RSES), and Brief Coping Orientation to Problems Experienced (COPE) Inventory were administered., Results: PIU was identified in 81 (22.0%) of the 368 patients with schizophrenia spectrum disorders. Subjects with PIU were significantly younger and more likely to be male. Scores on the HADS, PSS, and dysfunctional coping dimension of the Brief COPE Inventory were significantly higher, and RSES scores were significantly lower, in the PIU group. Logistic regression analysis indicated that PIU in patients was significantly associated with scores on the PSS and dysfunctional coping dimension of the Brief COPE Inventory., Conclusions: Patients with schizophrenia spectrum disorders and PIU were significantly more likely to have high levels of perceived stress and dysfunctional coping strategies. Patients with schizophrenia spectrum disorders who also engage in PIU may benefit from interventions that help them to develop appropriate skills for coping with stress., (Copyright © 2018 Elsevier Inc.

Objective: This study examined clinical and gender-specific risk factors for low bone mineral density (BMD) in adult patients with psychotic disorders., Methods: The study included 285 community-dwelling patients with psychotic disorders. Dual-energy X-ray absorptiometry was used to measure BMD. Clinical characteristics associated with low BMD were identified with logistic regression analysis in total population and each gender., Results: Fifty-eight (20.4%) subjects had low BMD. Low BMD was more common in men and in patients with low body mass indices (BMIs), as well as in those with shorter treatment durations, those on Medicaid, and patients using serotonergic antidepressants. Logistic regression analysis revealed that low BMD was negatively associated with BMI and treatment duration and positively with gender (male) and serotonergic antidepressants use in the overall population. In men, low BMD was associated with treatment duration and BMI; in women, low BMD was associated with BMI, prolactin level, vitamin D, and serotonergic antidepressant use., Conclusion: Managing the risk factors associated with low BMD among patients with psychotic disorder should be done gender-specifically. Psychotropic agents should be prescribed mindful of their effects on bone, as use of these medications is a modifiable risk factor for osteoporosis in women with psychotic disorders., (Copyright © 2018 John Wiley & Sons, Ltd.)

Inappropriate dietary intake and poor nutritional status are reported to be associated with metabolic syndrome and psychopathology in patients with schizophrenia. We hypothesized that inappropriate dietary habits and insufficient dietary intake of specific nutrients are associated with schizophrenia. To test the hypothesis, we assessed the dietary habits and nutritional intake of patients with schizophrenia and then developed suitable dietary guidelines. In total, 140 subjects (73 controls and 67 patients with schizophrenia from community mental health centers) were included, and dietary intakes were analyzed using a semi-quantitative food frequency questionnaire. As a result, the proportion of overweight or obese patients was significantly higher in schizophrenia subjects (64.2%) compared with control subjects (39.7%) (P=.004). The male schizophrenia patients had significantly lower dietary intakes of protein, polyunsaturated fatty acids (PUFAs), vitamin K, niacin, folate, and vitamin C than the male control subjects. In all multiple logistic regression models, subjects with the "low" dietary intake of protein, n-3 PUFAs, niacin, folate, and vitamin C had a significantly higher odds ratios for schizophrenia compared with those with the "high" dietary intake category of each nutrient. Therefore, maintenance of a healthy body weight and sufficient dietary intake of protein, PUFAs, niacin, folate, and vitamin C are recommended for Korean patients with schizophrenia., (Copyright © 2017 Elsevier Inc.

Objective: This study aims to investigate the factors associated with sexual function in Korean patients with schizophrenia., Methods: This study evaluated 169 patients with schizophrenia who were receiving risperidone monotherapy. The Visual Analog Scale was used to assess sexual function in terms of sexual desire, sexual arousal, and sexual satisfaction. The Positive and Negative Syndrome Scale, the Beck Depression Inventory, the Korean version of the Subjective Well-being under Neuroleptic Treatment-Brief Form (SWN-K) scale, and the Drug Attitude Inventory (DAI) were also administered., Results: Sexual function was negatively associated with age, duration of illness, gender (female), marital status (single), the presence of tardive dyskinesia, and Beck Depression Inventory score, but positively associated with the SWN-K and DAI scores. A linear regression analysis revealed that being male and married had significant positive associations with sexual arousal, sexual satisfaction, and/or sexual desire, while the presence of tardive dyskinesia and a longer duration of illness were associated with poor sexual arousal and/or sexual desire. Additionally, sexual function was significantly associated with the SWN-K and DAI scores in multivariate analysis., Conclusions: The acknowledgement and management of sexual dysfunction in patients with schizophrenia by clinicians may be important for improvement of their quality of life and adherence to medication., (Copyright © 2015 John Wiley & Sons, Ltd.)

This study aimed to investigate the association of obsessive-compulsive symptoms with clinical and neurocognitive features in patients with schizophrenia. This study enrolled 163 people with schizophrenia who were receiving risperidone monotherapy. Comorbid obsessive-compulsive symptoms were assessed using the Yale-Brown Obsessive-Compulsive Scale, and subjects with a score ≥ 10 constituted the obsessive-compulsive symptom group (n=30, 18.4%). The learning index was significantly higher in patients with obsessive-compulsive symptoms than in those without such symptoms after adjusting for age, stage (early and chronic), duration of illness, and CDSS score. However, there was no significant interaction between obsessive-compulsive symptoms and stage of illness. Scores on Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia, and Beck Depression Inventory were significantly higher in the obsessive-compulsive symptom group. In addition, the Subjective Well-being under Neuroleptic Treatment score was significantly lower in the obsessive-compulsive symptom group. In conclusion, comorbid obsessive-compulsive symptoms in patients with schizophrenia were associated with a higher learning ability without a significant interaction with stage of illness. However, schizophrenia patients with obsessive-compulsive symptoms had more severe psychotic and depressive symptoms and poorer quality of life., (Copyright © 2015 Elsevier Ireland Ltd.

The current prescription rate of long-acting injectable antipsychotics (LAI) is less than 1% in Korea. This study aimed to investigate the reason for LAI underuse by surveying the attitudes toward LAI among psychiatrists and patients receiving LAI. A total of 173 psychiatrists and 99 patients receiving LAI participated in the survey. Participating psychiatrists were divided into two groups according to experience with prescribing LAI to at least 10 patients. The two psychiatrist groups did not differ significantly in terms of sociodemographic characteristics and clinical practice patterns. However, the group with higher experience more frequently provided explanations of LAI to their patients and was more satisfied with the use of LAI than the group with less experience. Acceptance rates of patients to the recommendation for LAI treatment and satisfaction of psychiatrists with the outcome of LAI were also significantly higher in the group with higher experience. Psychiatrists with less experience with LAI were more negative toward LAI than patients receiving LAI as well as psychiatrists with higher experience. In conclusion, attitudes of psychiatrists toward LAI were closely related to the use of LAI. The negative attitude and reluctance of psychiatrists, rather than patient resistance, may contribute toward the underuse of LAI.

This study aims to determine the effectiveness of paliperidone extended release (ER) on cognitive function in patients with schizophrenia in comparison with risperidone. This was a 12-week, randomized, open-label study on schizophrenia patients who were receiving risperidone. The patients were randomized to a risperidone-continuation group or a paliperidone-switch group. The primary outcome measure was neurocognitive function, which was measured using a computerized battery. Secondary efficacy measures included the Positive and Negative Syndrome Scale, Social and Occupational Functioning Scale, and Calgary Depression Scale for Schizophrenia. In total, 58 patients participated in this trial. Improvements in recall after an interference phase in the verbal learning test were significantly greater in the paliperidone-switch than in the risperidone-continuation group. No significant differences in changes were observed in the other six neurocognitive domains measured. Improvements in the Social and Occupational Functioning Scale were significantly greater in the paliperidone ER-switch group than in the risperidone-continuation group. In other efficacy outcome measures, no significant differences were observed between the two drugs. Paliperidone ER had a side-effect profile similar to that of risperidone, including metabolic problems and prolactin-related adverse events. In conclusion, switching from risperidone to paliperidone ER may lead to additional cognitive and social functional improvements., (© 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.)

Objectives: Aripiprazole and ziprasidone are 2 antipsychotic medications that are relatively devoid of the metabolic adverse effects associated with the second-generation antipsychotics. This study aimed to evaluate the effectiveness of switching to ziprasidone in patients who had insufficient response or intolerance to aripiprazole for the treatment of schizophrenia., Methods: Nineteen patients receiving aripiprazole treatment for schizophrenia participated in this open-label 12-week study. Outcome measures included the Positive and Negative Syndrome Scale, Social and Occupational Functioning Assessment Scale, Calgary Depression Scale for Schizophrenia, Beck Depression Inventory, and Subjective Well-being under Neuroleptics Scale. Safety measures included metabolic parameters and scales to evaluate extrapyramidal adverse effects., Results: After switching to ziprasidone from aripiprazole, significant improvement of scores on the negative symptom subscale of the Positive and Negative Syndrome Scale, the Social and Occupational Functioning Assessment Scale, the Calgary Depression Scale for Schizophrenia, and the Beck Depression Inventory were observed at the study end point evaluation. Metabolic parameters including body weight, waist and hip circumferences, fasting blood glucose, and alanine aminotransferase showed statistically significant decreases. However, serum prolactin levels were significantly increased, and sedation was the most common adverse event., Conclusions: Switching to ziprasidone in patients with schizophrenia who showed insufficient response or intolerance to aripiprazole improved depression, negative symptoms, and metabolic disturbances. However, sedation and hyperprolactinemia were commonly associated with the switch to ziprasidone.

Objective: To investigate changes in cognitive function and clinical features following a switch from oral atypical antipsychotics (AAPs) to long-acting injectable risperidone (LAIR) in patients with schizophrenia., Methods: Thirty-six patients with schizophrenia treated with oral AAPs participated in this open-label, 26-week study. Cognitive functions were measured at baseline and at 12 and 26 weeks. The secondary outcome measures included the Positive and Negative Syndrome Scale (PANSS), Social and Occupational Functioning Assessment Scale (SOFAS), Scale for Unawareness of Mental Disorder (SUMD), and measurements for extrapyramidal symptoms., Results: Significant improvements in cognitive function were observed in the backward Digit Span Test, Verbal Learning Test, Wisconsin Card Sorting Test, correct responses on the Continuous Performance Test, and Trail Making Test part B following a switch to LAIR. Scores on the PANSS, SOFAS, SUMD, and the Simpson-Angus Rating Scale also improved significantly. Most improvements in neurocognitive function were not correlated with clinical measures. Weight gain and hyperprolactinemia were the most common adverse events., Conclusions: Switching from oral AAPs to LAIR improved cognitive function including vigilance, verbal learning and memory, executive function, sustained attention, and visuomotor speed in patients with schizophrenia. It was also effective for improving psychotic symptoms, social functioning, and insight.

Objective: To examine changes in cognitive function and clinical features after a switch from atypical antipsychotics to aripiprazole in patients with schizophrenia., Method: Sixty-one patients with schizophrenia treated with atypical antipsychotics participated in this open-label, 26-week study. Antipsychotics were switched to aripiprazole, and neurocognitive functions were measured at 12 and 26 weeks using the computerized battery. The secondary outcome measures were the Positive and Negative Syndrome Scale, the Social and Occupational Functioning Assessment Scale, the Calgary Depression Scale for Schizophrenia, the Subjective Well-being Under Neuroleptics Scale, and the Drug Attitude Inventory (DAI). The safety measures included metabolic parameters, the Simpson-Angus Rating Scale, the Barnes Akathisia Scale, and the Abnormal Involuntary Movement Scale., Results: Significant improvements in cognitive function were observed in the Verbal Learning Test, the Wisconsin Card Sorting Test, and the Trail Making Test part A after a switch to aripiprazole. Scores on the Positive and Negative Syndrome Scale, the Social and Occupational Functioning Assessment Scale, the DAI, the Simpson-Angus Rating Scale, and the Abnormal Involuntary Movement Scale were significantly improved. The metabolic parameters, including serum cholesterol levels, were also improved. The changes in cognitive measures were not correlated with the changes in positive symptoms or movements scales. The improvement of the scores on the DAI and the delayed recall of the Verbal Learning Test were significantly greater in the patients treated with antipsychotics for less than 1 year than in those treated for more than 1 year, in whom the improvement in metabolic parameters was significantly greater., Conclusions: Patients with schizophrenia who switched from their previous antipsychotics to aripiprazole demonstrated improvements in cognitive function, psychotic symptoms, social function, attitude toward medication, and metabolic abnormalities.

Atypical antipsychotics have been reported to induce or exacerbate obsessive-compulsive symptoms (OCS) in patients with schizophrenia. We report the development of de novo obsession induced by sequential treatment with risperidone, aripiprazole, and ziprasidone, which have an antagonist effect on serotonin 5-HT(2A) receptors in a patient with schizophrenia. The obsession was repeatedly improved after switching the atypical antipsychotics to amisulpride, a selective D(2) and D(3) receptor antagonist. To our knowledge, this is the first report about ziprasidone-induced OCS in a patient with schizophrenia. In conclusion, this case supports the hypothesis that the antagonist effect on 5-HT(2) receptors may be related to atypical antipsychotic-induced OCS.

Objective: To determine the effectiveness of amisulpride on depression in patients with schizophrenia, in comparison to risperidone., Method: In this open-label, 12-week study, patients with stable schizophrenia and a comorbid major or minor depressive episode (DSM-IV) taking risperidone were randomized into a risperidone-continuation group (N = 45) or an amisulpride-switch group (N = 42). The main outcome measures were changes from baseline on the Calgary Depression Scale for Schizophrenia (CDSS) and the Beck Depression Inventory (BDI). Secondary efficacy measures included the Positive and Negative Syndrome Scale (PANSS), and the Global Assessment of Functioning. Safety measures included treatment-emergent adverse events and extrapyramidal symptoms., Results: The mean dose at endpoint was 4.2 mg/day for risperidone and 458.3 mg/day for amisulpride. Improvements in the CDSS and BDI scores were significantly greater in the amisulpride-switch group than in the risperidone-continuation group at weeks 8 and 12, and at the endpoint. The amisulpride-switch group also showed a significantly greater reduction in the score for the PANSS depression/anxiety factor, and the total score from baseline to endpoint. No significant difference was observed between the two groups for treatment-emergent adverse events or change from baseline for extrapyramidal symptoms., Conclusion: Switching from risperidone to amisulpride in patients with stable schizophrenia with comorbid depression improved depressive symptoms significantly compared to continuing with risperidone.

Data on the use of long-acting injectable (LAI) risperidone, the first atypical depot antipsychotic, during pregnancy are limited. A 35-year-old woman with schizophrenia was given LAI risperidone before and throughout her pregnancy. She gave birth to a female infant weighing 2230 g at 36 weeks and 6 days of pregnancy, following premature rupture of the membranes. The baby had no congenital malformation and was healthy 8 months postnatal. To our knowledge, this is the first reported use of LAI risperidone throughout an entire pregnancy. In this paper, we discuss the rationale and problems of LAI risperidone use in pregnancy, based on a literature review.

The aim of this study was to examine the diagnostic validity of four commonly used assessment scales for depression in schizophrenia. The study population consisted of 84 inpatients meeting the DSM-IV criteria for schizophrenia. Depression in the study subjects was defined by the DSM-IV criteria for major depressive episode. The Positive and Negative Syndrome Scale (PANSS) and the Simpson-Angus Rating Scale (SARS) were used to differentiate depression from the negative and extrapyramidal symptom-related depressive phenomena in schizophrenia. The following four depression scales were assessed for their diagnostic validity as measures of depressive disorder in schizophrenia: the Calgary Depression Scale for Schizophrenia (CDSS), the Beck Depression Inventory (BDI), the Hamilton Rating Scale for Depression (HAM-D), and the depression subscale of the PANSS (PANSS-D). Of 84 patients with schizophrenia, 32 were diagnosed as having comorbid depressive disorder. The areas under the Receiver Operating Characteristic (ROC) curves of the CDSS, HAM-D, PANSS-D, and BDI were 0.94, 0.89, 0.90, and 0.81, respectively. The area under the ROC curve of the CDSS was significantly greater than that of the BDI and tended to be more favorable than those for the HAM-D and the PANSS-D. Our study suggests that the CDSS may provide the best assessment for depression in patients with schizophrenia.

Objectives: A patient's attitude toward medication is important for medication adherence, which is a key determinant of outcome in schizophrenia. This study examined the association between attitude toward antipsychotic medication and clinical status, particularly neurocognitive function, in patients with schizophrenia., Method: Ninety-two patients meeting the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for schizophrenia participated in this study. The attitudes of the subjects toward medication were evaluated using the Drug Attitude Inventory (DAI). Clinical characteristics, including psychiatric symptoms and side effects of medication were evaluated. Neurocognitive function was measured using the Mini Mental State Examination and a computerized battery consisting of the Digit Span Test, Verbal Learning Test, Continuous Performance Test, Wisconsin Card Sorting Test, Finger Tapping Test, and Trail Making Test, parts A and B. The associations between attitude toward medication and neurocognitive function and clinical characteristics were analyzed., Results: The scores on the DAI were not significantly correlated with the clinical characteristics, such as psychopathology, subjective well-being, or neuroleptic-induced extrapyramidal side effects. Instead, the scores on the DAI were significantly correlated with the learning index and delayed free recall on the Verbal Learning Test, the number of categories completed on the Wisconsin Card Sorting Test, and omission and commission errors on the Continuous Performance Test; the scores were not significantly correlated with measures on the Mini Mental State Examination, Digit Span Test, Finger Tapping Test, or Trail Making Test., Conclusions: Our findings indicate that a patient's attitude toward medication is associated with neurocognitive function. Specifically, verbal learning memory, executive functioning, and sustained attention were associated with attitude toward medication.

Objectives: Food cravings may cause weight gain in patients with schizophrenia. This study investigated psychological characteristics associated with food cravings in patients with first-episode psychosis. Methods: This study analyzed data from a clinical cohort of first-episode psychosis patients taking antipsychotics for 3 months or less. The strength of food cravings was measured using the General Food Cravings Questionnaire-Trait (G-FCQ-T). Psychological characteristics and psychiatric symptoms were investigated with the Positive and Negative Symptom Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS), Social and Occupational Functioning Assessment Scale, Rosenberg Self-Esteem Scale (RSES), and Perceived Stress Scale (PSS). Clinical characteristics were compared according to significant weight gain (≥10% increase in body weight compared to baseline) over 3 months. Associations between the G-FCQ-T and other psychiatric scales were investigated. We conducted sex-stratified analyses. Results: In total, 182 patients (78 males and 104 females) with first-episode psychosis were enrolled in this study. In females, the G-FCQ-T total score at baseline was associated with baseline body weight and significant weight gain over 3 months. The PSS scales were significantly associated the G-FCQ-T total and all subscale scores in female participants. Scores on the RSES and CDSS were significantly associated with the G-FCQ-T total score and with the preoccupation and loss of control subscale scores. The PANSS negative and general subscales were significantly associated with the positive outcome expectancy and loss of control subscales of the G-FCQ-T, respectively. In males, the only significant association was between the loss of control subscale and RSES scores. Linear regression analysis showed significant associations of PSS scores with the total and all subscale scores of the G-FCQ-T despite the loss of significance for other variables. Conclusion: These results indicate that the food cravings in patients with first-episode psychosis, which were associated with weight gain, were influenced by perceived stress in females. To reduce food cravings in female patients with schizophrenia, interventions aimed at perceived stress should be considered. [ABSTRACT FROM AUTHOR]

Statins, which are widely used to treat hypercholesterolemia, have anti-inflammatory and anti-oxidant effects. These are thought to be responsible for the potential effects of statins on various psychiatric disorders. In this study, we comprehensively review the literature to investigate the effects of statins on various psychiatric disorders including depression, schizophrenia, and dementia. In addition, we review adverse effects and drug interactions of statins to give clinically useful information guiding statin use in the psychiatric field. Statins seem useful in reducing depression, particularly in patients with physical disorders such as cardiovascular disease. In patients with schizophrenia, negative symptoms may be reduced by adjuvant statin therapy. Studies on cohorts at risk for dementia have generally shown protective effects of statins, while those on treatment for dementia show inconsistent results. In conclusion, statins used in combination with conventional psychotropic medications may be effective for various psychiatric disorders including depression, schizophrenia, and dementia. Further study is required to determine optimal doses and duration of statin use for the treatment of psychiatric disorders. [ABSTRACT FROM AUTHOR]

Background: This article describes the development of the smartphone application for cognitive‐behavioural case management of young individuals with early psychosis and examines the acceptance and potential clinical benefits of this application through a pilot survey. Methods: Gwangju Bukgu‐Community Mental Health Center developed and launched a smartphone application (Heal Your Mind [HYM]) for cognitive‐behavioural case management and symptom monitoring. The HYM application for clients includes 6 main modules including thought record, symptom record, daily life record, official notices, communication and scales. The key module is the "thought record" for self‐directed cognitive‐behavioural treatment. When the client writes and sends the self‐cognitive‐behavioural therapy sheet to the case manager, the latter receives a notification and can provide feedback in real time. We conducted a survey to investigate the acceptance and feasibility of this approach among young clients with early psychosis. Results: A total of 24 clients with early psychosis participated in this survey. More than 80% of participants reported that it was easy to learn to use this application, and no one described this application as very complicated or reported that they needed a long time to learn how to use it. About 80% of participants were satisfied with this application, and 70% reported that they received help as a result of using this application. Conclusions: This study suggests that this smartphone application is useful for young individuals with early psychosis and that it may contribute to the development of both young customer‐ and case manager‐friendly systems for this clinical population.

Inclusion of 'attenuated psychosis syndrome (APS)' in the DSM-5 has been hotly debated because of the concern about stigmatising young patients with a 'psychosis risk' label. This study aimed to investigate whether current labeling terms such as 'at risk mental state', 'ultra-high risk' (UHR) and 'APS' are suitable for people who are at risk of psychosis. This study included 105 subjects (55 patients aged 15-25years who used an early interventional service to prevent psychosis and 50 professionals who worked with them). A questionnaire regarding their opinions about the stigma associated with the above labels and the Mental Health Consumers' Experience of Stigma scale were administered. The patients were less likely than the professionals to agree that there was stigma associated with the terms 'UHR' and 'APS'. Significantly more patients with a family history of psychosis and those who had transitioned to psychosis agreed that there was stigma associated with the term 'UHR' and/or that this term should be changed. Patients who agreed with the negative attitude items for the three labeling terms and the need to change the terms 'UHR' and 'schizophrenia' showed significantly higher scores on the Stigma scale. In conclusion, patients at risk of psychosis may experience less stigma related to labels than expected by professionals, suggesting that mental health professionals may not be able to help patients unless they listen to their views on nosological and treatment issues rather than make assumptions. Previous stigmatising experiences may have strengthened the stigma attached to this label. [ABSTRACT FROM AUTHOR]

This study investigated the relationship between erythrocyte membrane fatty acid (FA) levels and the severity of symptoms of individuals at ultra-high risk (UHR) for psychosis. Subjects of the present study consisted of 80 neuroleptic-naïve UHR patients. Partial correlation coefficients were calculated between baseline erythrocyte membrane FA levels, measured by gas chromatography, and scores on the Positive and Negative Syndrome Scale (PANSS), Global Assessment of Functioning Scale, and Montgomery–Asberg Depression Rating Scale (MADRS) after controlling for age, sex, smoking and cannabis use. Subjects were divided into three groups according to the predominance of positive or negative symptoms based on PANSS subscale scores; membrane FA levels in the three groups were then compared. More severe negative symptoms measured by PANSS were negatively correlated with two saturated FAs (myristic and margaric acids), one ω-9 monounsaturated FA (MUFA; nervonic acid), and one ω-3 polyunsaturated FA (PUFA; docosapentaenoic acid), and were positively correlated with two ω-9 MUFAs (eicosenoic and erucic acids) and two ω-6 PUFAs (γ-linolenic and docosadienoic acids). More severe positive symptoms measured by PANSS were correlated only with nervonic acid. No associations were observed between FAs and MADRS scores. In subjects with predominant negative symptoms, the sum of the ω-9 MUFAs and the ω-6:ω-3 FA ratio were both significantly higher than in those with predominant positive symptoms, whereas the sum of ω-3 PUFAs was significantly lower. In conclusion, abnormalities in FA metabolism may contribute to the neurobiology of psychopathology in UHR individuals. In particular, membrane FA alterations may play a role in negative symptoms, which are primary psychopathological manifestations of schizophrenia-related disability. [ABSTRACT FROM AUTHOR]

Abstract: The effects of antipsychotics on the brain-derived neurotrophic factor (BDNF) expression have been controversial. This study aimed to investigate the effects of chronic quetiapine administration on the BDNF mRNA expression in hippocampus and neocortex of rats with or without immobilization stress. The chronic administration (21 days) of quetiapine (10mg/kg) significantly attenuated the decreased BDNF mRNA expression in the both hippocampal and cortical regions of rats caused by immobilization stress, and significantly increased the BDNF mRNA expression in the dentate gyrus of rats even without the immobilization stress. These results could add some theoretical bases to explain why quetiapine may improve cognitive symptoms of schizophrenia by stimulating BDNF mRNA expression. [Copyright &y& Elsevier]
