RESUMO

BACKGROUND: Studies of quality of life among suicide attempters are limited while it is considered important for preventing reattempt of suicide. We investigated health related quality of life (HRQoL) in suicide attempters immediately after the suicide attempt and in the long term. METHODS: This was longitudinal data from a randomized controlled multicenter trial. The Japanese version of the Short Form Health Survey-36 as HRQOL measured at 0, 6, and 12 months after randomization. RESULTS: 799 patients (356 men and 443 women) were analyzed. At baseline, the mean physical component summary (PCS) and the mental component summary (MCS) scores were 34.56 and 35.15, respectively, and they were significantly low compared with those of the general population. PCS scores significantly improved from baseline to 6 months (p = 0.003), from baseline to 12 months (p < 0.0001), and from baseline to 12 months (p = 0.002). MCS scores significantly improved from baseline to 6 months (p < 0.0001) and from baseline to 12 months (p < 0.0001). However, neither PCS nor MCS scores reached those of the general population norm at 12 months post-suicide attempt. LIMITATIONS: Patients younger than 20 years and patients who self-harmed but were not admitted to an emergency department were excluded. CONCLUSION: This study presents a trajectory of HRQoL scores in suicide attempters from immediately after the suicide attempt to 1 year later. Further studies on HRQoL in suicide attempters are needed to elucidate the effective care for the attempters.

RESUMO

Previous cross-sectional studies have reported that adolescent patients with anorexia nervosa (AN) showed global gray matter volume (GMV) reductions at the acute phase which were restored at the weight-recovered phase, compared with healthy controls (HC). However, few studies have investigated white matter volume (WMV) or cortical thickness in the context of AN, and results have been inconsistent. Voxel-based morphometry analyses for GM and WM, and cortical thickness analyses for GM were conducted in 31 adolescent patients with AN (vs. 18 HC) in the acute phase, and 16 patients with AN (vs. 13 HC) in the follow-up weight-recovered phase, over an approximately 1-year follow-up interval. At the acute phase, the AN patients showed significant reductions of GMVs and cortical thickness in widespread brain regions, compared with HC. Significant WMV reductions were identified in the bilateral superior longitudinal fascicle, superior thalamic radiation, corona radiata, and fornix, pons, and medulla in the patients. At the weight-recovered phase, the AN patients showed a significant GMV reduction in the left hippocampus, and a WMV reduction in the pons, compared with the HC. There was no difference in cortical thickness between two groups at the weight-recovered phase. In conclusion, the widespread volumetric reductions in GM and WM, and reduced cortical thickness observed in AN patients in the acute phase were not evident in the follow-up weight-recovered phase. The volume reductions observed in the hippocampus and pons in the weight-recovered phase could potentially reflect delayed neurogenesis or recovery from starvation in the AN patients.

RESUMO

There are no validated biomarkers for schizophrenia (SCZ), a disorder linked to neural network dysfunction. We demonstrate that collapsin response mediator protein-2 (CRMP2), a master regulator of cytoskeleton and, hence, neural circuitry, may form the basis for a biomarker because its activity is uniquely imbalanced in SCZ patients. CRMP2's activity depends upon its phosphorylation state. While an equilibrium between inactive (phosphorylated) and active (nonphosphorylated) CRMP2 is present in unaffected individuals, we show that SCZ patients are characterized by excess active CRMP2. We examined CRMP2 levels first in postmortem brains (correlated with neuronal morphometrics) and then, because CRMP2 is expressed in lymphocytes as well, in the peripheral blood of SCZ patients versus age-matched unaffected controls. In the brains and, more starkly, in the lymphocytes of SCZ patients <40 y old, we observed that nonphosphorylated CRMP2 was higher than in controls, while phosphorylated CRMP2 remained unchanged from control. In the brain, these changes were associated with dendritic structural abnormalities. The abundance of active CRMP2 with insufficient opposing inactive p-CRMP2 yielded a unique lowering of the p-CRMP2:CRMP2 ratio in SCZ patients, implying a disruption in the normal equilibrium between active and inactive CRMP2. These clinical data suggest that measuring CRMP2 and p-CRMP2 in peripheral blood might reflect intracerebral processes and suggest a rapid, minimally invasive, sensitive, and specific adjunctive diagnostic aid for early SCZ: increased CRMP2 or a decreased p-CRMP2:CRMP2 ratio may help cinch the diagnosis in a newly presenting young patient suspected of SCZ (versus such mimics as mania in bipolar disorder, where the ratio is high).

RESUMO

The aim of this study was to examine the effectiveness of assertive case management intervention in preventing suicidal behaviour in self-poisoning patients. We conducted a secondary analysis of data from the ACTION-J study. Participants were self-poisoning patients with clear suicide intent admitted to emergency departments and with a primary psychiatric diagnosis (as per DSM-IV-TR axis 1). Patients were randomly assigned either to assertive case management or enhanced usual care. The primary outcome measure was the incidence of a first recurrent suicide attempt within 6 months. This study is registered at ClinicalTrials.gov (NCT00736918) and UMIN-CTR (C000000444). There were 297 self-poisoning patients in the intervention group and 295 in the control group. The primary outcome was significantly lower in the intervention group than in the control group. The incidence of a first recurrent suicide attempt within 1 and 3 months was also significantly lower in the intervention group, as was the number of overall self-harm episodes over the entire study period. Furthermore, the number of non-suicidal self-harm episodes and suicide attempts was significantly lower in the intervention group. Assertive case management is effective when promptly introduced in a hospital setting as an intervention following a suicide attempt, particularly for self-poisoning patients.

RESUMO

The hippocampus is thought to play an important role in conveying contextual information to the amygdala as the neural basis of panic disorder (PD). Previous studies have revealed functional abnormalities in the hippocampus in patients with PD compared with healthy control subjects (HC), but no study has reported volume abnormalities in the hippocampus or evaluated minute structural changes in the hippocampus in such patients. We thus investigated volume abnormalities in the subfields of the hippocampus to better understand the neurobiological basis of PD. The hippocampus was extracted from structural brain magnetic resonance images obtained from 38 patients with PD and 38 HC and then segmented into six subfields. The relative volume of each subfield was compared between the two groups. The severity of symptoms was assessed using the Panic Disorder Severity Scale (PDSS) and social functioning was assessed using the Global Assessment of Functioning (GAF) scale. Our results revealed that patients with PD had a significantly smaller volume of the right cornu ammonis (CA) 2/3 hippocampal subfield compared with HC. No significant associations were found between the volumes of the right CA 2/3 and the PDSS or GAF scores in correlation analyses. In conclusion, CA2/3 is thought to be related to contextual memory function, and our results suggest that this particular hippocampal subfield plays a role in the development of PD symptoms.

RESUMO

BACKGROUND: Although the pathogenesis of panic attacks has been well studied in patients with panic disorder (PD), the neurobiological basis of the long-term fear memories and avoidance behavior that are often observed in PD have not been well investigated. Recent animal studies have suggested that nucleus accumbens (NAcc) plays an important role in neurobiological basis of long-term fear memories and avoidance behavior. METHODS: Thirty-eight patients with PD and 38 matched healthy control subjects (HC) participated in this study. Differences in relative volumes and shape deformations of NAcc were evaluated between groups. Correlation analyses were conducted to quantify the association between structural abnormalities in the NAcc and trait, state anxiety measured by the State-Trait Anxiety Inventory (STAI). RESULTS: Significant volume reductions were observed in the bilateral NAcc in the patients with PD, relative to the HC. In terms of shape differences, the PD patients demonstrated significant inward deformation of the NAcc bilaterally, compared to the HC. Degree of shape deformation in the right NAcc was associated with higher scores of the STAI-Trait, and STAI-State measures in the PD patients. LIMITATIONS: All the patients received medication such as Psychotropic drug. CONCLUSION: Patients with PD showed reduced volumes in the NAcc, especially in lateral regions, compared with HC. Furthermore, shape deformation in the right NAcc was associated with trait anxiety and state anxiety, which has been associated with avoidance behavior.

RESUMO

BACKGROUND: Most suicide attempters suffer from psychiatric disorders, which are often comorbid with personality disorders. The effects of intervention on patients who have attempted suicide with comorbid Axis I and II diagnoses have not been fully elucidated. We evaluated whether assertive case management can reduce the repetition of suicidal behaviours in patients who had attempted suicide with comorbid Axis I and II diagnoses. METHODS: This study was a secondary analysis of a randomised controlled trial investigating whether assertive case management could reduce the repetition of suicide attempts, compared with enhanced usual care. Subjects were divided into those who had comorbid Axis I and II diagnoses (Axis I + II group), and those who had an Axis I diagnosis without Axis II comorbidity (Axis I group). Outcome measures were compared between patients receiving a case management intervention and patients receiving enhanced usual care, as allocated. The primary outcome measure was the incidence proportion of the first episode of recurrent suicidal behaviour at 6 months after randomisation. We calculated risk ratios (RR) with 95% confidence intervals (CI) at 6 months and 12 months after randomisation of patients in the Axis I and Axis I + II groups. RESULTS: Of 914 enrolled patients, 120 (13.1%) were in the Axis I + II group, and 794 (86.9%) were in the Axis I group. Assertive case management was significantly effective for the Axis I group on the primary outcome at 6 months (risk ratio [RR] 0.51, 95% confidence intervals [CI] 0.31 to 0.84). The RR of the Axis I + II group was 0.44 (95% CI 0.14 to 1.40). CONCLUSIONS: Assertive case management not only had an effect on patients who had attempted suicide with only Axis I disorders but may also have a similar effect on patients with comorbid Axis I and II disorders.

RESUMO

BACKGROUND: Hopelessness may be associated with an increased risk of suicide. However, findings regarding the long-term predictive ability of the Beck Hopelessness Scale (BHS) for suicide are inconsistent. This study investigated the long-term predictive ability of BHS scores for subsequent self-harm episodes in individuals admitted to an emergency department after attempting suicide. METHODS: The BHS was administered to 805 adult patients with a DSM-IV-TR axis I disorder admitted to an emergency department following a suicide attempt. The patients were followed for at least 18 months and up to 5 years. The incidence of the first subsequent suicidal behavior (attempt or dying by suicide) was examined and the numbers per person-year of overall repeat self-harm episodes, suicide attempt episodes, and non-suicidal self-harm episodes were evaluated. RESULTS: The total BHS scores showed significant associations with the overall number of self-harm episodes per person-year (incidence rate ratio [IRR], 1.05; 95% confidence interval [CI], 1.03-1.07; p < 0.0001), the number of suicide attempt episodes per person-year (IRR, 1.05; 95%CI, 1.03-1.08; p < 0.0001), and the number of non-suicidal self-harm episodes per person-year (IRR, 1.05; 95%CI, 1.03-1.07; p < 0.0001). LIMITATIONS: The study excluded children and adolescents. The sample size, while large, was insufficient to ensure generalizability, or to allow subanalyses based on specific disorders. CONCLUSIONS: Hopelessness scores assessed in the emergency department after a self-harming episode were associated with a rate of repetition of suicidal behaviors after discharge. Additional strategies to address hopelessness of these patients are warranted.

RESUMO

BACKGROUND: People with depression have autonomic function disturbances. In Japan, workers who take leave due to depression often undergo a work-focused intervention program called the return to work (RTW) program at a mental health hospital during their leave of absence. However, its biological efficacy remains unclear. We investigated the biological efficacy of the RTW program, including changes in autonomic nervous system (ANS) activity, in workers on sick leave due to depression in Japan. METHODS: The study involved 104 workers on sick leave due to major depressive disorder or bipolar disorder who underwent the RTW program for 3 months in Yokohama City University Hospital. The ANS activity of all patients was evaluated using heart rate variability at the beginning and end of the 3-month RTW program. Psychiatric symptoms were evaluated using the Montgomery-Åsberg Depression Rating Scale-Japanese (MADRS-J) and Social Adaptation Self-evaluation Scale (SASS). We followed up 3 months after the end of the program and investigated the association between the success in returning to work within 3 months after the end of the RTW program and several factors, including ANS activity, depressive symptoms, and demographic factors. RESULTS: Parasympathetic activity was significantly higher and depressive symptom severity was significantly lower at program end than at baseline. Logistic regression analysis showed that the change in depressive symptoms was significantly associated with success in returning to work. CONCLUSION: We suggest that the RTW program improves parasympathetic activity as well as psychiatric symptoms. ANS activity was not a predictor of a successful return to work within 3 months after the end of the program in workers on sick leave due to depression, but further studies with a larger sample size are needed.

RESUMO

AIMS: In this study, we implemented the Illness Management and Recovery (IMR) program for middle-aged and older patients with schizophrenia hospitalized for long periods and assessed the effect of the IMR program on psychiatric symptoms and psychosocial function. The effects of the IMR program on brain structure were also evaluated. METHODS: The IMR program was implemented for 19 patients with schizophrenia; 17 patients with schizophrenia receiving treatment as usual (TAU) were also recruited as controls. In all patients, mean age was 61.4 years (range, 50-77 years) and mean hospitalization duration was 13.1 years (range, 1-31 years) at enrollment. Structural magnetic resonance images and Positive and Negative Syndrome Scale (PANSS) and Global Assessment of Functioning (GAF) scores as clinical variables were obtained at the beginning and end of the IMR program. Longitudinal analyses were performed to compare the effects of the IMR program on clinical symptoms and cortical thickness in the superior temporal gyrus (STG) between the IMR and TAU groups. RESULTS: Significant improvements in GAF scores and the total, Insight and Judgment, and Positive components of the PANSS were found in the IMR group compared with the TAU group. Cortical thickness in the left STG was preserved in the IMR group compared with the TAU group. CONCLUSIONS: This is the first report demonstrating the effectiveness of the IMR program for improving psychotic symptoms and psychosocial function and protecting brain structure in middle-aged and older inpatients with schizophrenia hospitalized for long periods.

RESUMO

The thalamus is believed to play crucial role in processing viscero-sensory information, and regulating the activity of amygdala in patients with panic disorder (PD). Previous functional neuroimaging studies have detected abnormal activation in the thalamus in patients with PD compared with healthy control subjects (HC). Very few studies, however, have investigated for volumetric abnormalities in the thalamus in patients with PD. Furthermore, to the best of our knowledge, no previous study has investigated for shape abnormalities in the thalamus in patients with PD. Twenty-five patients with PD and 25 HC participants (all female) were recruited for the study. A voxel-wise volume comparison analysis and a vertex-wise shape analysis were conducted to evaluate structural abnormalities in the PD patients compared to HC. The patients with PD demonstrated significant gray matter volume reductions in the thalamus bilaterally, relative to the HC. The shape analysis detected significant inward deformation in some thalamic regions in the PD patients, including the anterior nucleus, mediodorsal nucleus, and pulvinar nucleus. PD patients showed shape deformations in key thalamic regions that are believed to play a role in regulating emotional and cognitive functions.

RESUMO

The amygdala plays an important functional role in fear and anxiety. Abnormalities in the amygdala are believed to be involved in the neurobiological basis of panic disorder (PD). Previous structural neuroimaging studies have found global volumetric and morphological abnormalities in the amygdala in patients with PD. Very few studies, however, have explored for structural abnormalities in various amygdala sub-regions, which consist of various sub-nuclei, each with different functions. This study aimed to evaluate for volumetric abnormalities in the amygdala sub-nuclei, in order to provide a better understanding neurobiological basis of PD. Thirty-eight patients with PD and 38 matched healthy control (HC) participants underwent structural MRI scanning. The volume of the whole amygdala, as well as its consistent sub-nuclei, were calculated using FreeSurfer software. Relative volumes of these amygdala sub-regions were compared between the two groups. Results showed significantly smaller volumes in the right lateral and basal nuclei in the patients with PD compared with the HC. Lateral and basal nuclei are thought to play crucial role for processing sensory information related with anxiety and fear. Our results suggest that these particular amygdala sub-regions play a role in the development of PD symptoms.

RESUMO

OBJECTIVE: Long-acting injections (LAIs) of antipsychotics show distinct pharmacokinetic profiles from oral antipsychotics (OAPs). Although there may be differences in adverse event frequency, any differences in their effects on autonomic nervous system (ANS) remain unclear. PATIENTS AND METHODS: In total, 270 schizophrenic patients were recruited in this study: 241 received OAPs (risperidone, olanzapine, quetiapine, or aripiprazole) and 29 received LAIs (risperidone LAI, aripiprazole LAI, or paliperidone palmitate) as monotherapy. Heart rate variability was measured as an index of ANS activity, and the low-frequency (0.03-0.15 Hz) component, high-frequency (0.15-0.40 Hz) component, and total power (0.03-0.40 Hz) were calculated. Components were compared between the groups using t-tests. RESULTS: A significant difference was detected in the low-frequency component between the OAP and LAI groups (P=0.046). No significant difference was found in total power or the high-frequency component between the two groups. CONCLUSION: Compared with OAPs, LAIs have fewer adverse effects on ANS activity, particularly the low-frequency component, as determined using a spectral analysis of heart rate variability.

RESUMO

BACKGROUND: Panic disorder (PD), an anxiety disorder characterized by the recurrence of panic attacks, has been reported to be associated with volumetric changes in several brain regions. There are, however, very few studies investigating abnormalities in cortical thickness, and little is known about the relationship between cortical thickness and social dysfunction in PD. METHODS: Thirty-eight patients with PD and 38 healthy control participants (HC) were recruited for this study. A whole-brain analysis was performed to evaluate groupwise differences in cortical thickness using the FreeSurfer software. Symptom severity and social functioning were evaluated with the Panic Disorder Severity Scale (PDSS) and the Global Assessment of Functioning (GAF) scale. RESULTS: The patients with PD demonstrated a significant reduction in cortical thickness in the left rostral middle frontal cortex (MFC), compared with the HC. Correlational analyses revealed that cortical thickness in the left rostral MFC showed a significant negative relationship with PDSS score and a significant positive relationship with GAF scores in the PD patients. LIMITATIONS: All the patients received medication. CONCLUSION: PD patients showed reduced cortical thickness in the left rostral MFC compared with HC. Furthermore, cortical thickness in this region was associated with patients' symptom severity and degree of social dysfunction.

RESUMO

BACKGROUND: Patients with schizophrenia have a higher mortality risk than the general population. Additionally, the autonomic nervous system (ANS) activity of patients with schizophrenia is lower and more dysfunctional than that of the general population. Nonetheless, the association between ANS dysfunction and mortality in schizophrenia is unclear. The aim of this study was to investigate the association between ANS activity and mortality in schizophrenia and to evaluate the predictive values of heart rate variability for long-term survival. METHODS: This study involves the 10-year follow-up of a sample population consisting of 59 Japanese inpatients with schizophrenia between 60 and 70 years of age from 2007 to 2016. The ANS activity of all patients was evaluated using heart rate variability in 2007. RESULTS: Fifty-three participants could be followed up because they stayed in the hospital during the follow-up period. Of these patients, 11 died during follow-up. Their mean age at death was 70.55 ±â€¯3.45 years. The parasympathetic activity of nonsurvivors was significantly lower than that of survivors, and multiple logistic regression analysis showed a significant association between death and parasympathetic activity. CONCLUSION: We suggest that decreased parasympathetic activity could be associated with 10-year all-cause mortality in older schizophrenic patients.

RESUMO

BACKGROUND: There are interindividual differences in the adverse effects of atypical antipsychotics, which include autonomic nervous system (ANS) dysfunction. Accordingly, to clarify the interindividual differences in the adverse effects of specific atypical antipsychotics in schizophrenia, we investigated the association between ANS dysfunction and ATP-binding cassette transport sub-family B member 1 (ABCB1) gene polymorphisms in patients with schizophrenia. METHODS: In total, 233 Japanese patients with schizophrenia participated in this study. All of the participants received an atypical antipsychotic as monotherapy: 89 participants received risperidone, 69 olanzapine, 48 aripiprazole, and 27 quetiapine. ANS activity was assessed by means of a power spectral analysis of heart rate variability. Four single nucleotide polymorphisms (SNPs) in ABCB1 (rs1045642, rs1128503, rs2032582, and rs2235048) were genotyped using the TaqMan method. RESULTS: For aripiprazole, sympathetic and total autonomic nervous activities were significantly lower in the rs1045642 T allele carrier-rs2235048 C allele carrier group than in the rs1045642 non-T allele carrier-rs2235048 non-C allele carrier group. In addition, in the aripiprazole group, the T-C-T-A haplotype (rs1045642-rs2235048-rs1128503-rs2032582) was associated with decreased ANS activity. However, there were no significant associations between ANS activity and ABCB1 gene polymorphisms in the risperidone, olanzapine, and quetiapine groups. Multiple regression analysis revealed that sympathetic and total nervous activities were significantly associated with the ABCB1 rs1045642-rs2235048 genotype and the T-C-T-A haplotype (rs1045642-rs2235048-rs1128503-rs2032582). CONCLUSION: We suggest that ABCB1 genetic polymorphisms affect aripiprazole-related ANS dysfunction but do not affect risperidone-, olanzapine-, or quetiapine-related ANS dysfunction.

RESUMO

We examined whether abnormal volumes of several brain regions as well as their mutual associations that have been observed in patients with schizophrenia, are also present in individuals at clinical high-risk (CHR) for developing psychosis. 3T magnetic resonance imaging was acquired in 19 CHR and 20 age- and handedness-matched controls. Volumes were measured for the body and temporal horns of the lateral ventricles, hippocampus and amygdala as well as total brain, cortical gray matter, white matter, and subcortical gray matter volumes. Relationships between volumes as well as correlations between volumes and cognitive and clinical measures were explored. Ratios of lateral ventricular volume to total brain volume and temporal horn volume to total brain volume were calculated. Volumetric abnormalities were lateralized to the left hemisphere. Volumes of the left temporal horn, and marginally, of the body of the left lateral ventricle were larger, while left amygdala but not hippocampal volume was significantly smaller in CHR participants compared to controls. Total brain volume was also significantly smaller and the ratio of the temporal horn/total brain volume was significantly higher in CHR than in controls. White matter volume correlated positively with higher verbal fluency score while temporal horn volume correlated positively with a greater number of perseverative errors. Together with the finding of larger temporal horns and smaller amygdala volumes in the left hemisphere, these results indicate that the ratio of temporal horns volume to brain volume is abnormal in CHR compared to controls. These abnormalities present in CHR individuals may constitute the biological basis for at least some of the CHR syndrome.

RESUMO

BACKGROUND: Self-harm is an important risk factor for subsequent suicide and repetition of self-harm, and a common cause of emergency department presentations. However, there still remains limited evidence on intervention in emergency department settings for individuals who self-harm. METHODS: This multicentre, randomised controlled trial was conducted at 17 general hospitals in Japan. In total, 914 adult patients admitted to emergency departments for a suicide attempt and had a DSM-IV-TR axis I disorder were randomly assigned to two groups, to receive either assertive case management (intervention) or enhanced usual care (control). Assertive case management was introduced by the case manager during emergency department admissions for suicide attempts, and continued after discharge. Interventions were provided until the end of the study period (for at least 18 months and up to 5 years). RESULTS: The number of overall self-harm episodes per person-year was significantly lower in the intervention group (adjusted incidence risk ratio (IRR) 0.88, 95%CI 0.80-0.96, p=0.0031). Subgroup analysis showed a greater reduction of overall self-harm episodes among patients with no previous suicide attempt at baseline (adjusted IRR 0.73, 95% CI 0.53-0.98, p=0.037). LIMITATIONS: Patients younger than 20 years and patients who self-harmed but were not admitted to an emergency department were excluded. CONCLUSIONS: The present study showed that assertive case management following emergency admission for a suicide attempt reduced the incident rate of repeat overall self-harm.
