Incidence and clinical course of major depression in patients with chronic hepatitis type C undergoing interferon-alpha therapy: a prospective study.

This study examined the incidence, clinical course and its risk factors for major depression in patients with chronic hepatitis type C undergoing interferon-alpha therapy. Ninety-nine subjects underwent the psychiatric interviews for diagnosis of major depressive episode according to the DSM-IV criteria before the start of interferon therapy, and once every 4 weeks during both the 24-week treatment period and 12 weeks after the end of therapy. Depressive symptoms were also evaluated using the Hamilton Rating Scale for Depression. Major depression occurred during interferon therapy in 23 patients (23.2%). In 73.9% of them depression occurred within 8 weeks after the start of therapy. Twenty-two patients with depression completed the therapy and 59.1% of them achieved remission by the end of therapy with a mean duration of 11.6 weeks. Although the other 40.9% were not in remission at the end of therapy, they achieved remission within 12 weeks thereafter. The only risk factor for depression was advanced age. Depression occurs frequently among patients with hepatitis type C undergoing interferon-alpha therapy. Such patients require careful observation, and psychiatrists should be sufficiently aware of this significant psychiatric complication of interferon therapy.

Treatment for delirium with risperidone: results of a prospective open trial with 10 patients

Delirium is a common psychiatric illness among medically compromised patients. There is an increasing opportunity to use atypical antipsychotics to treat delirium. The effects of these drugs on delirium, however, the most appropriate way to use them, and the associated adverse effects remain unclear. To clarify these points, a prospective open trial on risperidone was carried out in 10 patients with delirium. At a low dose of 1.7 mg/d, on average, risperidone was effective in 80% of patients, and the effect appeared within a few days. There were no serious adverse effects. However, sleepiness (30%) and mild drug-induced parkinsonism (10%) were observed; the symptom of sleepiness was a reason for not increasing the dose. One patient responded to a dose as low as 0.5 mg/d, so it is recommended that treatment start at a low dose, which may then be increased gradually. This trial is a preliminary open study with a small sample size, and further controlled studies will be necessary.

Changes in disclosure of information to cancer patients in a general hospital in Japan

The disclosure of information to cancer patients is one of the most important issues in oncological practice. In Japan, as in some other countries, few cancer patients were ever given a truthful statement of their diagnosis. However, today more and more patients are being informed of their diagnosis and prognosis. This study investigates the nature of these changes in disclosure policy and suggests possible explanations. We reviewed the medical and nursing charts of 122 adult cancer patients admitted to our hospital in 1993 and 137 admitted in 1998. We examined the information they had been given, and their sociodemographic and medical characteristics. The diagnosis of cancer was shared with 27% of patients in 1993. In 1998, however, 71% were informed of their cancer, and 10% were also told they had a poor prognosis. The rate of disclosure was lower for older patients and those with advanced cancer in both 1993 and 1998. In 1998 the rate was higher in patients undergoing chemotherapy and/or surgery. The higher level of disclosure in 1998 was due basically to the growing importance of informed consent. Psychiatric referrals increased from 2% in 1993 to 10% in 1998. Psychiatrists may have contributed to these changes in the disclosure of information.

The disclosure of information to cancer patients and its relationship to their mental state in a consultation-liaison psychiatry setting in Japan.

In Japan, as in some other countries, not all cancer patients are informed of their diagnosis and expected prognosis. However, we do not know enough about the relationship between the kind of information given to cancer patients and their mental state. The following is a study that examines this relationship. The subjects were 81 adult cancer inpatients referred to psychiatrists. Those with mental disorders before admission or with delirium were excluded. The subjects were classified into three groups according to the kind of information given to them: 28 were not informed of a diagnosis of cancer, 36 were informed of a diagnosis of cancer, and 17 were informed of both a diagnosis of cancer and a poor prognosis. The distributions of DSM-IV Axis I diagnoses were nearly equal among the three groups of patients. In each group, more than 90% of patients were diagnosed as having either major depressive disorder or adjustment disorders. In the results of HAM-D, HAM-A, and a question about irritability, the mean total HAM-A scores and mean scores for the factors of Suicide, Behavior at Interview, and Irritability, differed significantly among the three groups. They were highest in patients who were not informed of a diagnosis of cancer. The authors discuss the nature of relationship between the disclosure of information and the mental state in cancer patients.

Assertive case management versus enhanced usual care for people with mental health problems who had attempted suicide and were admitted to hospital emergency departments in Japan (ACTION-J): a multicentre, randomised controlled trial

BACKGROUND Non-fatal suicide attempt is the most important risk factor for later suicide. Emergency department visits for attempted suicide are increasingly recognised as opportunities for intervention. However, no strong evidence exists that any intervention is effective at preventing repeated suicide attempts. We aimed to investigate whether assertive case management can reduce repetition of suicide attempts in people with mental health problems who had attempted suicide and were admitted to emergency departments. METHODS In this multicentre, randomised controlled trial in 17 hospital emergency departments in Japan, we randomly assigned people aged 20 years and older with mental health problems who had attempted suicide to receive either assertive case management (based on psychiatric diagnoses, social risks, and needs of the patients) or enhanced usual care (control), using an internet-based randomisation system. Interventions were provided until the end of the follow-up period (ie, at least 18 months and up to 5 years). Outcome assessors were masked to group allocation, but patients and case managers who provided the interventions were not. The primary outcome was the incidence of first recurrent suicidal behaviour (attempted suicide or completed suicide); secondary outcomes included completed suicide and all-cause mortality. This study is registered at ClinicalTrials.gov (NCT00736918) and UMIN-CTR (C000000444). FINDINGS Between July 1, 2006, and Dec 31, 2009, 914 eligible participants were randomly assigned, 460 to the assertive case management group and 456 to the enhanced usual care group. We noted no significant difference in incidence of first recurrent suicidal behaviour between the assertive case management group and the enhanced usual care group over the full study period (log-rank p=0·258). Because the proportional hazards assumption did not hold, we did ad-hoc analyses for cumulative incidence of the primary outcome at months 1, 3, 6, 12, and 18 after randomisation, adjusting for multiplicity with the Bonferroni method. Assertive case management significantly reduced the incidence of first recurrent suicidal behaviour up to the 6-month timepoint (6-month risk ratio 0·50, 95% CI 0·32-0·80; p=0·003), but not at the later timepoints. Prespecified subgroup analyses showed that the intervention had a greater effect in women (up to 18 months), and in participants younger than 40 years and those with a history of previous suicide attempts (up to 6 months). We did not identify any differences between the intervention and control groups for completed suicide (27 [6%] of 460 vs 30 [7%] of 454, log-rank p=0·660) or all-cause mortality (46 [10%] of 460 vs 42 [9%] of 454, log-rank p=0·698). INTERPRETATION Our results suggest that assertive case management is feasible in real-world clinical settings. Although it was not effective at reducing the incidence of repetition of suicide attempts in the long term, the results of our ad-hoc analyses suggested that it was effective for up to 6 months. This finding should be investigated in future research. FUNDING The Ministry of Health, Labour, and Welfare of Japan.

Stress coping and social support in glucose tolerance abnormality

We examined coping with stress, including social support, dealing with illness, and mood states, in a sample of 600 persons who underwent primary health-care screening. Subjects were not yet diagnosed as having glucose tolerance abnormality and considered themselves healthy before the examination. Although no significant differences on the existence and perception of social support were found, the utilization of social support was significantly and negatively correlated with the level of glucose tolerance abnormality. The results suggest that poor utilization of social support is associated with the onset of glucose tolerance abnormality.

Risperidone in the Treatment of Acute Confusional State (Delirium) Due to Neuropsychiatric Lupus Erythematosus: Case Report:

Acute confusional state (delirium) appears as one of the common neuropsychiatric manifestations of systemic lupus erythematosus (SLE). It has been suggested that neuropsychiatric SLE (NP-SLE) could promote the occurrence of drug-induced extrapyramidal symptoms (EPS). Atypical antipsychotics have been thought to be useful in management of delirium because of their low incidence of adverse effects including EPS. However, no reports of the use of atypical antipsychotics in delirium due to NP-SLE have been published. Here we report a case of NP-SLE presenting an acute confusional state (delirium), which was successfully managed by risperidone.

Effectiveness of group cognitive-behavioral therapy in reducing self-stigma in Japanese psychiatric patients

OBJECTIVE There is evidence that the stigma surrounding mental illness may be greater in Japan than elsewhere. However, few Japanese studies have focused on self-stigma (the internalization of social stigma), and few interventions to reduce self-stigma exist. To remedy this deficiency, we evaluated the efficacy of group cognitive-behavioral therapy (CBT) in reducing self-stigma and examined the relationship between cognitive restructuring and self-stigma. METHODS We administered a 10-session group CBT program to 46 Japanese outpatients with anxiety and depressive symptoms (36 men, 10 women; mean age=38.57 years, SD=8.33; 20 diagnosed with mood disorders; 24 with neurotic, stress-related, or somatoform disorders; and 2 with other disorders). A pretest-posttest design was used to examine the relationship between cognitive restructuring and self-stigma. Outcomes were measured using the Japanese versions of the Devaluation-Discrimination Scale, Dysfunctional Attitude Scale, Beck Depression Inventory-II, State-Trait Anxiety Inventory State-Form, and Rosenbergs Self Esteem Scale. RESULTS Participants exhibited significant improvements in depression, anxiety, and maladjusted cognitive bias and reductions in self-stigma. Cognitive bias was significantly correlated with self-stigma. CONCLUSIONS Group CBT is effective in improving both emotional symptoms and self-stigma in outpatients with anxiety and depressive symptoms. Reduction in self-stigma plays a mediating role in alleviating emotional symptoms and improving cognition.

An investigation of anxiety about radiotherapy deploying the Radiotherapy Categorical Anxiety Scale

BackgroundRadiotherapy is one of the major methods for treating cancer, but many patients undergoing radiotherapy have deep concerns about receiving radiation treatment. This problem is not generally appreciated and has not been adequately studied.MethodsThe objective of this investigation was to empirically investigate the anxieties that cancer patients feel towards radiotherapy by using questionnaires to classify and quantitatively measure their concerns. A preliminary interview to develop a questionnaire was carried out with 48 patients receiving radiotherapy to discover their anxieties about on-going treatments. Subsequently, a main study was performed using a questionnaire with 185 patients to classify their types of anxiety and to ascertain the reliability and validity of the responses. Confirmatory factor analysis was then carried out with a 17-item Radiotherapy Categorical Anxiety Scale.ResultsThree anxiety factors were abstracted by factor analysis: (1) adverse effects of radiotherapy, (2) environment of radiotherapy, and (3) treatment effects of radiotherapy. Reliability, content validity, and concurrent validity were obtained. The adequacy of the three-factor model of anxiety concerning radiotherapy was confirmed.ConclusionA 17-item Radiotherapy Categorical Anxiety Scale was formulated to quantitatively measure the specific types of anxiety among cancer patients receiving radiotherapy.

Content Analysis of Group Work Sessions in the Context of an Educational Program for Inpatient Diabetes Patients

This study investigated the changes in emotions and attitudes of diabetic patients as observed in group work sessions linked to an inpatient diabetic educational program. Using content analysis of transcripts from Sessions 1 and 3 of 8 selected groups (40 patients), in Session 1 negative emotions or attitudes such as anxiety, remorse, or self-blame, a lack of understanding of diabetes, along with a willingness to undertake self-care were frequently expressed. In Session 3, more positive emotions and attitudes towards self-care (willingness, specific plans, and resolutions), satisfaction, and relief or hope were frequently expressed. These results suggest that the patients participating in the group work sessions moved toward adaptation to diabetes, although the effects of the group work were not separated from those of the inpatient educational program.
