The neural basis of maternal responsiveness to infants: an fMRI study.

Using fMRI, we examined the neural correlates of maternal responsiveness. Ten healthy mothers viewed alternating blocks of video: (i) 40 s of their own infant; (ii) 20 s of a neutral video; (iii) 40 s of an unknown infant and (iv) 20 s of neutral video, repeated 4 times. Predominant BOLD signal change to the contrasts of infants minus neutral stimulus occurred in bilateral visual processing regions (BA 19,21,37,38); to own infant minus unknown infant in right anterior temporal pole (BA 38), left amygdala and visual cortex (BA 19), and to the unknown infant minus own infant contrast in bilateral orbitofrontal cortex (BA 10,47) and medial prefrontal cortex (BA 8) [corrected] These findings suggest that amygdala and temporal pole may be key sites in mediating a mother's response to her infant and reaffirms their importance in face emotion processing and social behaviour.

A national audit of joint mother and baby admissions to UK psychiatric hospitals: an overview of findings.

The Marcé Clinical Audit is an ongoing data collection exercise that gathers socio-demographic and clinical information about mothers and their infants, admitted jointly to specialist units in UK psychiatric hospitals. The maternal and parenting outcomes, in particular of mothers with schizophrenia and mothers who harm themselves and/or their infants, were determined and analysed. The majority of women had a primary diagnosis of either depression (43%) or schizophrenia (21%). Mothers with schizophrenia were three times more likely to experience a poor outcome than non-schizophrenic mothers, were more likely to be separated from their infant at discharge and were perceived, by staff, to be at greater risk of harming their infant. They were, however, shown to be no more likely to cause actual harm to their infant, or themselves, than non-schizophrenic mothers.

Defining the needs of patients with intellectual disabilities in the high security psychiatric hospitals in England.

BACKGROUND: Previous studies have suggested that a substantial proportion of the patients with intellectual disabilities (ID) in the high security psychiatric hospitals (HSPHs) should be transferred to more appropriate services to cater for their specific needs in the longer term. METHOD: The individual and placement needs of high secure psychiatric patients detained under the legal category of mental impairment or severe mental impairment were assessed in a cross-sectional survey. RESULTS: Patients had a large number of needs (on average 10.8), about a third of which were rated as unmet and therefore represented significant continuing problems. Approximately one-third of the sample could be moved out of HSPHs if appropriate alternatives were available. Factors associated with the continued need for high security included higher treatment and security needs, younger age, recent violent conduct and their index offence profile. CONCLUSIONS: High security services are still required for a number of patients with ID. New and existing services need to be configured to meet specific profiles of need and provide long-term rehabilitation and specialist care. DECLARATION OF INTEREST: This was part of a larger project funded by grants from the High Security Psychiatric Services Commissioning Board and Department of Health.

Predictors of parenting outcome in women with psychotic disorders discharged from mother and baby units.

OBJECTIVE: To compare the social and clinical characteristics of mothers with psychotic disorders with parenting difficulties, with mothers with no significant parenting problems. METHOD: Descriptive and case-control study. RESULTS: Over half of the women with psychotic disorders admitted to psychiatric mother and baby units had a good outcome at the time of discharge--70% did not need social services supervision, and had no significant parenting problem as judged by clinical staff. Diagnosis was independently associated with all measures of poor parenting; compared with a diagnosis of psychotic depression, a diagnosis of schizophrenia was highly significantly associated with social services supervision [adjusted odds ratio (OR) 25.7; 95% CI 5.97, 111.05], and staff rated problems with emotional responsiveness (adjusted OR 3.39;95% CI 1.42, 8.08), practical baby care (adjusted OR 6.07; 95% CI 2.12, 17.39), and perceived risk of harm to baby (adjusted OR 7.81; 95% CI. 2, 30.53). Low social class and psychiatric illness in the partner were also significantly associated with poor parenting outcomes, including social services supervision (adjusted OR 3.88; 95% CI 2.07, 7.25 and 4.23; 95% CI 2.1, 8.55, respectively). CONCLUSIONS: Although these associations do not demonstrate causality, these findings suggest preventative interventions targeting socio-economic difficulties, early treatment of psychosis, and detection and treatment of psychiatric problems in the partner may be helpful in improving parenting outcomes in these vulnerable families.

Life events preceding suicide by young people.

BACKGROUND: Life events are often reported to precede suicide. This paper aims to determine the frequency, timing and type of life events preceding suicide by young people and those with and without a mental illness. METHOD: Informants, usually family members, were interviewed for a sample of young (less than 35 years) suicides. Information was recorded on events occurring in the 6 months before death. Equivalent information was obtained for living controls who had been matched for age and gender and obtained through the general practices of the suicides. RESULTS: Suicide was associated with life events in the previous 3 months, and particularly in the previous week. Specifically, interpersonal and forensic (being arrested, charged or sentenced) events distinguished suicides and controls. The number of life events in the different time periods under study did not distinguish suicides with and without severe mental illness, although more suicides without a severe mental illness had a reported life event in the week before their death. CONCLUSIONS: Adverse life events frequently precede suicide in young people with and without severe mental illness. However, recent life events may have a lesser causal role in those with severe mental illness. Clinical and health promotion measures to improve the way that young people cope with interpersonal problems and other crises may be an important part of any suicide prevention strategy.

Health of children considered for adoption.

Children in the 'care' system are known to have poor health. Although health services can respond to and deal with health problems, it is parents, foster parents and social workers who recognize problems, seek advice and keep follow-up appointments. Many health needs remain unmet in such children. This short paper from a deprived area in north-east England shows that once a decision is made to proceed to adoption, the stable and consistent care that can then be provided meets the increased health needs that such children have.

Effects of legislation restricting pack sizes of paracetamol and salicylate on self poisoning in the United Kingdom: before and after study.

OBJECTIVE: To evaluate the effects on suicidal behaviour of legislation limiting the size of packs of paracetamol and salicylates sold over the counter. DESIGN: Before and after study. SETTING: UK population, with detailed monitoring of data from five liver units and seven general hospitals, between September 1996 and September 1999. SUBJECTS: People who died by suicidal or accidental overdose with paracetamol or salicylates or who died of undetermined causes; patients admitted to liver units with hepatic paracetamol poisoning; patients presenting to general hospitals with self poisoning after taking paracetamol or salicylates. MAIN OUTCOME MEASURES: Mortality from paracetamol or salicylate overdose; numbers of patients referred to liver units or listed for liver transplant; numbers of transplantations; numbers of overdoses and tablets taken; blood concentrations of the drugs; prothrombin times; sales to pharmacies and other outlets of paracetamol and salicylates. RESULTS: Numbers of tablets per pack of paracetamol and salicylates decreased markedly in the year after the change in legislation on 16 September 1998. The annual number of deaths from paracetamol poisoning decreased by 21% (95% confidence interval 5% to 34%) and the number from salicylates decreased by 48% (11% to 70%). Liver transplant rates after paracetamol poisoning decreased by 66% (55% to 74%). The rate of non-fatal self poisoning with paracetamol in any form decreased by 11% (5% to 16%), mainly because of a 15% (8% to 21%) reduction in overdoses of paracetamol in non-compound form. The average number of tablets taken in paracetamol overdoses decreased by 7% (0% to 12%), and the proportion involving >32 tablets decreased by 17% (4% to 28%). The average number of tablets taken in salicylate overdoses did not decrease, but 34% fewer (2% to 56%) salicylate overdoses involved >32 tablets. After the legislation mean blood concentrations of salicylates after overdose decreased, as did prothrombin times; mean blood concentrations of paracetamol did not change. CONCLUSION: Legislation restricting pack sizes of paracetamol and salicylates in the United Kingdom has had substantial beneficial effects on mortality and morbidity associated with self poisoning using these drugs.

Psychiatric morbidity in patients undergoing heart, heart and lung, or lung transplantation.

OBJECTIVES: To determine the rate of psychiatric disorder in people undergoing heart and/or lung transplantation; to identify the associations of psychiatric disorder in this group. METHOD: Preoperative assessments were carried out on an 18-month sample of consecutive admissions to a regional unit for heart and lung transplantation in the UK. Assessment included psychiatric morbidity, sexual dysfunction, quality of life, and demographic and clinical characteristics. RESULTS: Seventy-six of 79 eligible subjects took part in the assessment. Thirty (39%) were suffering from a psychiatric disorder, the most common being major depressive disorder. Forty-four (58%) reported sexual dysfunction. Clinically significant psychiatric morbidity was associated with a history of treatment for mental disorder, unemployment, and length of physical illness. Patients with psychiatric disorder reported poorer quality of life on the SF-36, with lower scores on subscales for general health perception, social functioning, and energy/vitality. CONCLUSION: There is a substantial rate of psychiatric disorder in people undergoing heart and/or lung transplantation. Risk is higher in people with a history of psychiatric vulnerability and current illness-related factors. Preoperative psychiatric assessment and intervention in some patients may be a valuable part of their clinical care.

The Family Response Questionnaire: a new scale to assess the responses of family members to people with chronic fatigue syndrome.

OBJECTIVE: Family responses to patients with chronic fatigue syndrome (CFS) may influence the course of the disorder and family members themselves are likely to be adversely affected. However, the beliefs and responses of relatives of CFS patients have been under-researched. The aim of this study was to produce an easy-to-administer questionnaire to assess the responses of family members to people with CFS. METHODS: Seventy-eight people, all close relatives of (physician-diagnosed) CFS sufferers, completed the first version of the Family Response Questionnaire (FRQ). RESULTS: Examination of the correlation matrix and a cluster analysis of the items support four scales rather than the original five. The four response scales were labelled: sympathetic-empathic, active engagement, rejecting-hostile, and concern with self. Measures of test-retest and internal reliability were high. Participants found the items both comprehensible and relevant to their experiences of living with people with CFS. CONCLUSION: The new version of the FRQ will be useful in further examination of the responses of CFS on individuals and their families.

Changes in rates of suicide by car exhaust asphyxiation in England and Wales.

BACKGROUND: Self-asphyxiation using car exhaust gas is a common method of suicide in England and Wales, particularly in young males. The introduction of catalytic converters has reduced the toxicity of car exhausts. The main aims of the study were: to seek evidence of a fall in car exhaust suicides in the general population and in age and gender groups; to relate any fall to changes in car exhaust systems, particularly since legislation on car exhaust emissions in 1993; and to examine rates of suicide by other methods for evidence of method substitution. METHODS: Population study in England and Wales using national suicide statistics for 1987 to 1998. RESULTS: There was a fall in suicide by car exhaust asphyxiation in all age and gender groups. This change was most marked after 1993. The overall population suicide rate (all methods) also fell but there was no overall change in suicides by young males or females. In these groups suicide by hanging increased. CONCLUSIONS: Legislation on catalytic converters appears to have contributed to a fall in car exhaust suicides. However, the effect on overall suicide rates in young people has been reduced by method substitution.

Immunization with recombinant Opc outer membrane protein from Neisseria meningitidis: influence of sequence variation and levels of expression on the bactericidal immune response against meningococci.

The opc gene from Neisseria meningitidis was cloned into the pRSETA vector, and recombinant protein was expressed at high levels in Escherichia coli. The protein was readily purified by affinity chromatography and used for immunization with conventional Al(OH)3 adjuvant or after incorporation into liposomes and Zwittergent micelles. The resulting sera were analyzed for their ability to recognize purified recombinant protein and "native" protein in an enzyme immunoassay with outer membranes and by whole-cell immunofluorescence. Immunization with Al(OH)3 induced high levels of antibodies which reacted with the purified protein but did not recognize whole cells. In contrast, liposomes and micelles induced antibodies which reacted with the native protein in whole cells. The addition of monophosphoryl lipid A (MPLA) to either liposomes or micelle preparations increased the magnitude of the immune response and induced a wider range of immunoglobulin subclasses. This was associated with the ability of the sera to induce complement-mediated killing of the homologous strain. The most effective bactericidal activity was observed with Opc protein incorporated into liposomes containing MPLA. The magnitude of the bactericidal effect was strongly influenced by the level of expression of the Opc protein and was abolished by limited variation in the sequence of the protein expressed by heterologous strains.

Attitudes toward suicide prevention in front-line health staff.

A questionnaire assessing attitudes toward suicide prevention was constructed and shown to have satisfactory reliability and internal consistency. The determinants and distribution of these attitudes were investigated in four groups of health professionals who are in contact with suicidal patients: general practitioners, accident and emergency nurses, psychiatrists in training, and community psychiatric nurses. Attitudes toward suicide prevention were shown to differ significantly between professional groups. More positive attitudes were associated with mental health professionals, working in the community, and previous training in suicide risk assessment. Negative attitudes should be assessed and targeted in training designed to improve the management of suicide risk.

An educational intervention for front-line health professionals in the assessment and management of suicidal patients (The STORM Project).

BACKGROUND: Suicide prevention is a health priority in many countries. Improved management of suicide risk may improve suicide prevention. This study aimed to assess the feasibility of health district-wide training in the assessment and management of people at risk of suicide; and to assess the impact of training on assessment and management skills. METHODS: Staff in three health care settings, namely primary care, accident and emergency departments and mental health services (N = 359), were offered suicide risk management training in a district-wide programme, using a flexible 'facilitator' approach. The main outcomes were the rate of attendance at training, and changes in suicide risk assessment and management skills following training. RESULTS: It was possible to deliver training to 167 health professionals (47 % of those eligible) during a 6 month training period. This included 95 primary care staff (39%), 21 accident and emergency staff(42%) and 51 mental health staff (78%). Of these, 103 (69%) attended all training. A volunteer sample of 28 staff who underwent training showed improvements in skills in the assessment and management of suicide risk. Satisfaction with training was high. The expected costs of district-wide training, if it were able to produce a 2.5% reduction in the suicide rate, would be 99,747 pound sterling per suicide prevented and 3,391 pound sterling per life year gained. CONCLUSIONS: Training in the assessment and management of suicide risk can be delivered to approximately half the targeted staff in primary care, accident and emergency departments and mental health services. The current training package can improve skills and is well accepted. If it were to produce a modest fall in the suicide rate, such training would be cost-effective. However, a future training programme should develop a broader training package to reach those who will not attend.
