Randomized controlled trial of brief cognitive behaviour therapy versus treatment as usual in recurrent deliberate self-harm: the POPMACT study.

BACKGROUND: We carried out a large randomized trial of a brief form of cognitive therapy, manual-assisted cognitive behaviour therapy (MACT) versus treatment as usual (TAU) for deliberate self-harm. METHOD: Patients presenting with recurrent deliberate self-harm in five centres were randomized to either MACT or (TAU) and followed up over 1 year. MACT patients received a booklet based on cognitive behaviour therapy (CBT) principles and were offered up to five plus two booster sessions of CBT from a therapist in the first 3 months of the study. Ratings of parasuicide risk, anxiety, depression, social functioning and global function, positive and negative thinking, and quality of life were measured at baseline and after 6 and 12 months. RESULTS: Four hundred and eighty patients were randomized. Sixty per cent of the MACT group had both the booklet and CBT sessions. There were seven suicides, five in the TAU group. The main outcome measure, the proportion of those repeating deliberate self-harm in the 12 months of the study, showed no significant difference between those treated with MACT (39%) and treatment as usual (46%) (OR 0.78, 95% CI 0.53 to 1.14, P=0.20). CONCLUSION: Brief cognitive behaviour therapy is of limited efficacy in reducing self-harm repetition, but the findings taken in conjunctin with the economic evaluation (Byford et al. 2003) indicate superiority of MACT over TAU in terms of cost and effectiveness combined.

User involvement in the planning and delivery of mental health services: a cross-sectional survey of service users and providers.

OBJECTIVE: To identify methods for involving service users in the planning and delivery of psychiatric services and factors which may assist and impede this process. METHOD: A cross-sectional postal survey of user groups and providers of psychiatric services throughout Greater London (UK). RESULTS: Seventeen (94%) service providers and 29 (48%) user groups responded to the survey. Service providers employed a wide variety of different methods for involving users but none met national standards for user involvement (UI). Service providers stated that the main obstacle to UI was that users who took part were not representative of local patients. User groups highlighted staff resistance as a major obstacle and 80% stated that they were not satisfied with current arrangements for UI. CONCLUSION: While users and providers of mental health services were able to identify changes resulting from UI the responsiveness of staff and the representativeness of service users may be impeding this process.

Reducing violence in severe mental illness: randomised controlled trial of intensive case management compared with standard care.

OBJECTIVES: To establish whether intensive case management reduces violence in patients with psychosis in comparison with standard case management. DESIGN: Randomised controlled trial with two year follow up. SETTING: Four inner city community mental health services. PARTICIPANTS: 708 patients with established psychotic illness allocated at random to intervention (353) or control (355) group. INTERVENTION: Intensive case management (caseload 10-15 per case manager) for two years compared with standard case management (30-35 per case manager). MAIN OUTCOME MEASURE: Physical assault over two years measured by interviews with patients and case managers and examination of case notes. RESULTS: No significant reduction in violence was found in the intensive case management group compared with the control group (22.7% v 21.9%, P=0.86). CONCLUSIONS: Intensive case management does not reduce the prevalence of violence in psychotic patients in comparison with standard care.

Relatives of patients with severe psychotic illness: factors that influence appraisal of caregiving and psychological distress.

BACKGROUND: Research shows considerable variability in the effect on relatives of patients' mental illness but the determinants of relatives' experience remain unclear. We investigated the influence of demographic, social and clinical characteristics on relatives' experience when conceptualised using a stress-appraisal-coping paradigm. METHODS: Our sample was drawn from relatives of patients recruited to the UK700 case management study (n = 154). Demographic, social and clinical data were collected from patients, and relatives completed the Experience of Caregiving Inventory and the General Health Questionnaire. We predicted that patients' symptomatology in particular would influence relatives' experience, and that relatives who appraised caregiving more negatively and less positively would experience greater psychological distress. RESULTS: Linear regression analyses revealed that relatives' appraisal was not predicted by patients' symptomatology. Instead, relatives appraised caregiving more negatively if the patient was unemployed or younger, and less positively if the patient had been ill for longer or had poorer social functioning. Little of the variance in appraisal was explained by these variables, however. Consistent with the stress-coping model, relatives' negative appraisal was a strong predictor of psychological distress and accounted for a substantial proportion of its variance. Positive appraisal did not predict psychological distress, however. None of the demographic, social or clinical characteristics tested had any significant effect on relatives' psychological distress once appraisal was adjusted for. There was an unexpected positive correlation between the two appraisal scales, with relatives who appraised caregiving more negatively also appraising it more positively. CONCLUSIONS: Our results support a stress-coping model of caregiving but further research is required to determine more influential predictors of relatives' appraisal. Our findings indicate that interventions aimed at patients' social functioning and relatives' negative appraisal of caregiving may assist in reducing relatives' psychological distress.

Does socioeconomic status predict course and outcome in patients with psychosis?

BACKGROUND: We examined the relationship between socioeconomic status (SES) and course and outcome of patients with psychosis. Two hypotheses were examined: a) patients with higher best-ever SES will have better course and outcome than those with lower best-ever SES, and b) patients with greater downward drift in SES will have poorer course and outcome than those with less downward drift. METHOD: Data were drawn from the baseline and 2-year follow-up assessments of the UK700 Case Management Trial of 708 patients with severe psychosis. The indicators of SES used were occupational status and educational achievement. Drift in SES was defined as change from best-ever occupation to occupation at baseline. RESULTS: For the baseline data highly significant differences were found between best-ever groups and negative symptoms (non-manual vs. unemployed--coef -10.5, p=0.000, 95% CIs 5.1-15.8), functioning (non-manual vs. unemployed--coef -0.6, p=0.000, 95% CIs 0.3 to -0.8) and unmet needs (manual vs. unemployed - coef 0.5, p=0.004, 95% CIs 0.2-0.9). No significant differences between best-ever groups were found for days in hospital, symptoms, perceived quality of life and dissatisfaction with services. Significant differences for clinical and social variables were found between drift and non-drift SES groups. There were no significant findings between educational groups and clinical and social variables. CONCLUSIONS: Best-ever occupation, but not educational qualifications, appeared to predict prognosis in patients with severe psychosis. Downward drift in occupational status did not result in poorer illness course and outcome.

Combination antiangiogenic therapy: increased efficacy in a murine model of Wilms tumor.

BACKGROUND/PURPOSE: Antibody to vascular endothelial growth factor (anti-VEGF) suppresses tumor growth and metastasis in experimental Wilms tumor. However, tumor growth accelerates if antibody is withdrawn. As recently shown, low-dose, frequently administered topotecan, a topoisomerase-1 inhibitor, has anti-angiogenic activity. The authors hypothesized that combined topotecan/anti-VEGF therapy would suppress tumor growth and metastasis more durably than either agent alone. METHODS: Xenografts were induced by intrarenal injection of human Wilms tumor cells in athymic mice (n = 59). Mice were divided into control (n = 10), anti-VEGF (n = 16), topotecan (n = 17), and topotecan plus anti-VEGF (n = 16) groups. All control and half the treated mice were killed at week 6. Remaining ("rebound") mice were maintained without treatment until week 8. Tumor vasculature was mapped by fluorescein angiography/PECAM immunostaining. Endothelial apoptosis was assessed by TUNEL assay. RESULTS: 6 weeks: Tumor weights were reduced significantly in treated mice (P <.003 v control). Seven of ten control and 1 of 25 treated mice displayed lung metastases (P <.003). Rebound tumors were largest in topotecan-only, intermediate in antibody-treated, and smallest in combination-treated mice. Immunostaining and angiography results showed sparse vascularity in treated xenografts. Endothelial apoptosis was observed only in treated tumors. CONCLUSION: Combination low-dose topotecan and anti-VEGF antibody therapy is antiangiogenic and suppresses tumor growth and metastasis in experimental Wilms tumor more durably than either agent alone.

Novel use of an established agent: Topotecan is anti-angiogenic in experimental Wilms tumor.

BACKGROUND/PURPOSE: Antiangiogenic agents offer a new approach to the treatment of aggressive neoplasms, yet very few agents are available for current use. The authors have shown previously the efficacy of antiangiogenic therapy in experimental Wilms tumor, using an investigative antibody. They hypothesized that topotecan, administered in a regimen targeting endothelial cells, would suppress tumor growth and angiogenesis in experimental Wilms tumor. METHODS: Experimental tumors were induced in the left kidneys of athymic mice by injection of cultured Wilms tumor cells. Topotecan (0.36, 0.6, 1.0, 2.0, and 3.0 mg/kg) or vehicle was injected intraperitoneally in 2 cycles over a 6-week period. Fluorescein angiograms and platelet endothelial cell adhesion molecule-1 staining of primary tumors were performed to ascertain vascular architecture. Endothelial apoptosis was assessed by TdT-mediated dUTP nick end labeling assay. RESULTS: Tumor weights were reduced significantly in treated versus control animals, even in the lowest-dose group. Endothelial cell staining and angiography results showed relatively sparse vascularity in treated xenografts. Endothelial apoptosis was observed in treated but not control tumors. CONCLUSIONS: Topotecan, delivered in an "antiangiogenic" regimen, even at very low doses, significantly inhibited growth of experimental Wilms tumors. No adverse effects were noted at low doses. Thus, the established chemotherapy agent topotecan may be useful in a novel role: as antiangiogenic therapy. J Pediatr Surg 36:1781-1784.

Personality abnormality in severe mental illness and its influence on outcome of intensive and standard case management: a randomised controlled trial.

One hundred fifty-five (77%) of 201 participants recruited in a trial of intensive vs standard case management of patients with recurrent psychotic illness had their personality status measured before treatment and were followed up for two years. The primary outcome was the total number of days spent in psychiatric hospitalisation in the two years following randomisation. Thirty-three (21%) of the patients had a personality disorder and their duration of hospital stay (105 days) was greater than in those without personality disorder (56 days). There was weak evidence that intensive case management more effective in reducing the duration of care in those with personality disorder than in those without personality disorder.

Problems in developing an instrument for the rapid assessment of personality status.

PURPOSE: To assess the validity of a quick assessment instrument (10 minutes) for assessing personality status, the Rapid Personality Assessment Schedule (PAS-R). SUBJECTS AND METHODS: The PAS-R was evaluated in psychotic patients recruited in one of the centres involved in a multicentre randomised controlled trial of intensive vs standard case management (the UK700 case management trial). Patients were assessed using both a full version of the PAS (PAS-I - ICD version) and the PAS-R. The weighted kappa statistic was used to gauge the (criterion-related) validity of the PAS-R using the PAS-I as the gold standard. Both measure code personality status using a four-point rating of severity in addition to recording individual categories of personality disorder. RESULTS: One hundred fifty-five (77%) of 201 patients recruited were assessed with both instruments. The weighted kappa statistic was 0.31, suggesting only moderate agreement between the PAS-I and PAS-R instruments under the four-point rating format, and 0.39 for the dichotomous personality disorder/no disorder separation. The sensitivity (64%) and specificity (82%) of the PAS-R in predicting PAS-I personality disorder were as satisfactory as for other screening instruments but still somewhat disappointing, and the PAS-R had an overall diagnostic accuracy of 78%. CONCLUSION: The PAS-R is a quick and rough method of detecting personality abnormality but is not a substitute for a fuller assessment.

Suppression of primary tumor growth in a mouse model of human neuroblastoma.

BACKGROUND/PURPOSE: Neuroblastoma is the most common tumor of the abdomen in children. Consistently effective treatments are lacking for aggressive disease. The authors previously reported that therapy with anti-vascular endothelial growth factor (VEGF) antibodies suppresses both growth and metastasis in an experimental model of Wilms' tumor. The authors hypothesized that, in a parallel model of neuroblastoma, anti-VEGF treatment would inhibit (1) growth and (2) metastasis. METHODS: Primary tumors were established in the kidneys of nude mice. In cohort 1 (n = 42), mice were killed at 3 time-points, and tissues were evaluated histologically. Tumors were assayed for VEGF. In cohort 2 (n = 28), anti-VEGF antibody or vehicle was administered. Tumor weights and the incidence of metastases in the 2 groups were compared. VEGF deposition was evaluated by immunohistochemistry. RESULTS: Mice displayed large tumors with liver and lung metastases. VEGF levels in tumors increased over time. Antibody-treated animals displayed significantly smaller tumors, but incidence and size of metastases were unaffected. VEGF was localized to tumor stroma immunohistochemically, with no difference in pattern observed in control and antibody-treated tumors. CONCLUSIONS: Anti-VEGF antibodies inhibit primary tumor growth in experimental neuroblastoma, but not metastasis. This may contrast with the effect of the same antibody in a parallel model of Wilms' tumor.

Prevalence and predictors of parasuicide in chronic psychosis. UK700 group.

OBJECTIVE: This study estimates the prevalence of and risk factors for parasuicide in a large community-based sample of patients with chronic psychosis. METHOD: A total of 704 subjects with chronic psychosis were interviewed using a battery of instruments. The 2-year prevalence of parasuicide was estimated and a comparison was made between attempters and nonattempters on a wide range of sociodemographic and clinical variables. RESULTS: The 2-year prevalence of parasuicide was 18.8%. Attempters were significantly more likely to be younger, of white ethnic origin, to have a diagnosis of affective disorder, to be currently depressed, to have experienced more auditory hallucinations and to have received treatment with antipsychotic drugs for a longer period. CONCLUSION: Parasuicide was found to present a considerable clinical problem in this group. Continual risk assessment is essential to reduce this unacceptably high rate.

Medical withdrawals from college for mental health reasons and their relation to academic performance.

A collaborative study among the university health service, the dean's office, and the registrar's office examined the academic performance of 77 students who took medical withdrawals for mental health reasons from Dartmouth College during a 3-year period. In 71.4% of the cases, students withdrew from a term in progress; the remainder arranged to withdraw after they had completed a term but before starting a new term. Depression was a major factor in approximately half of the withdrawals. Grade point average improved significantly after return from the withdrawal, with a large jump in individual term averages occurring between the terms immediately preceding and immediately following return. We found no significant difference between the number of students who experienced disciplinary trouble before withdrawal and those who were disciplined afterward. Students who were depressed at the time of withdrawal did not fare as well academically upon return as those students who had not been depressed. The data suggest that procedures for handling mental health withdrawals and readmission are important ways in which the campus counseling center can support the university's academic mission.
