Integration of a suicide risk assessment and intervention approach: the perspective of youth.

The process of suicide risk assessment is often a challenge for mental health nurses, especially when working with an adolescent population. Adolescents who are struggling with particular problems, stressors and life events may exhibit challenging and self-harm behaviour as a means of communication or a way of coping. Current literature provides limited exploration of the effects of loss, separation and divorce, blended families, conflict and abuse on child and adolescent development and the increased vulnerability of at-risk youth. There is also limited research that provides clear and practical models for the assessment and management of youth suicidal ideation and behaviour. This paper will discuss the integration of a number of theories to establish a comprehensive assessment of risk. The research study described the perspective of youth and their families who had experienced this particular model; however, this paper will discuss only the youth perspective. In order for this model to be successful, it is important for mental health nurses to make a connection with the youth and begin to understand the self-harm behaviour in context of the adolescents' family, and their social and school experiences. It also requires recognition that adolescents with challenging and self-harm behaviour are hurting and troubled adolescents with hurtful and troublesome behaviour.

Bipolar disorder. III: Harm avoidance a risk factor for suicide attempts.

OBJECTIVES: The aim of the study was to examine whether personality, i.e. temperament and character influence suicide attempts in bipolar patients. METHODS: Bipolar patients were recruited from lithium dispensaries. Temperament and character inventory (TCI) was administered to 100 euthymic bipolar patients and 100 controls. RESULTS: Age of onset was significantly lower in patients with suicide attempts in the total bipolar group (I and II) and bipolar I patients compared with patients without suicide attempts. Bipolar (I and II) and bipolar I patients with suicide attempts were significantly higher in harm avoidance (HA) and reward dependence compared with patients without suicide attempts. Patients (I and II) with suicide attempts had significantly more anticipatory worry, fatigability and asthenia than patients without suicide attempts. Bipolar I patients with suicide attempts had significantly more fatigability and asthenia and were more dependent than patients without suicide attempts. HA was lowest in patients with no suicide attempts and no family history of suicide, higher in patients with family history of suicide or patients with suicide attempts, and significantly highest in patients with suicide attempts and family history of suicide. Patients with suicide attempts and family history of suicide had more anticipatory worry, fatigability and asthenia. Bipolar disorder was significantly correlated to HA and suicide attempts to HA and PS. Family history of suicide and gender were significantly correlated to suicide attempts. CONCLUSIONS: Age of onset, HA, PS, gender and family history of suicide had a moderate to very strong effect on suicide attempts in bipolar patients.

On conflict, containment and the relationship between them.

A programme of research into conflict (e.g. violence, absconding, medication refusal) and containment (e.g. seclusion, special observation, physical restraint) in inpatient psychiatry has been under way at City University, London, UK, for the past 10 years. Recent research findings, plus the challenges posed by ongoing projects, have made apparent the need for greater clarity about the overarching concepts of 'conflict' and 'containment'. This paper pulls together research findings pertaining to this issue, and conducts a reasoned analysis of what common characteristics might underlie 'conflict' and 'containment'. It is concluded that these are patient threats to safety, and the staff maintenance of safety. Details are presented on the inclusions and exclusions that follow from taking such a position, and potential definitions offered. On the grounds of this conceptual analysis, plus evidence for moderate degrees of statistical association between behaviours and events in each domain, it is concluded that it is legitimate to conduct analyses at the level of total conflict and containment rates, as well as at the level of individual types of behaviours and events (e.g. verbal abuse, sedation). Some of the mathematical difficulties in the analysis of total conflict and containment are addressed, and results of a weighting exercise presented. This exercise challenges our perception of the severity of some containment measures that are becoming more commonly used in acute psychiatry.

Trait and state aspects of harm avoidance and its implication for treatment in major depressive disorder, dysthymic disorder, and depressive personality disorder.

The authors evaluated the trait/state issues of harm avoidance in depressive-spectrum disorders and its predictive potential for antidepressant response. Subjects with Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV) major depressive disorder (n = 39), dysthymic disorder (n = 37), depressive personality disorder (n = 39), and healthy control subjects (n = 40) were evaluated with the Temperament and Character Inventory and the 17-item Hamilton Depression Rating Scale (HDRS-17) at baseline and after a 12 week antidepressant treatment period. Higher harm avoidance scores predicted lesser improvement in subjects with dysthymic disorder and major depressive disorder, as determined by lesser decrease in HDRS-17 scores. Mean harm avoidance scores in depressed subjects were consistently greater than those in healthy controls, controlling for age, gender and diagnosis. Mean harm avoidance scores decreased significantly in all depressive-spectrum disorders after treatment, but still remained higher than harm avoidance scores in control subjects. The present study reports that harm avoidance is a reliable predictor of antidepressant treatment in subjects with major depressive disorder and dysthymic disorder and that harm avoidance is both trait- and state-dependent in depressive-spectrum disorders.

Brain glucose metabolism and temperament in relation to severe somatization.

Little is known about the pathophysiology of somatization. The authors' aim was to explore associated factors with somatoform disorders. The authors studied 10 female patients with a diagnosis of somatization disorder or undifferentiated somatoform disorder with no comorbid current Diagnostic and Statistical Manual of Mental Disorders (4th edn) Axis I disorder and 12 healthy female volunteers. The predicting variables were temperament factors of the 240-item Temperament and Character Inventory instrument and regional brain glucose metabolism. Low novelty-seeking and high harm avoidance temperament traits and low caudate and low putamen glucose metabolism were statistically significantly associated with severe somatization (P < 0.05). In the present study, severe somatization associates with both altered brain glucose metabolism and temperament factors. No other studies on association of somatization with brain glucose metabolism and temperament have been published. The results are still considered exploratory due to the small number of subjects.

Cloninger's temperament dimensions and threat, stress, and performance appraisals during different challenges among young adults.

We examined the relationship of Cloninger's temperament factors-Novelty Seeking, Harm Avoidance, Reward Dependence, and Persistence-to perceived threat and stress and performance appraisals during different challenges, i.e., mental arithmetic, the reaction time task, and three public speaking tasks, among 97 young adult men and women. Temperament was measured by the Temperament and Character Inventory. The results showed that, although some of the predictions made by Cloninger's model were confirmed, some were unsupported. The results revealed also some associations between temperament and cognitive appraisals that were intelligible, but not predicted by Cloninger's model. There were considerable domain specificity and gender differences in the associations found. Cloninger's temperament dimensions are related to threat, stress, and performance appraisals, thereby influencing individual's stress vulnerability, adjustment, and personal functioning.

HIV and reproductive care--a review of current practice.

In developed countries, antiretroviral treatment has increased life quality and expectancy of HIV-infected individuals and led to a drop in mother-to-child transmission (MCT) risk to below 1%. Fertility has been shown to be reduced in both men and women with HIV. As a result of these factors, the demand for reproductive care in this population is rising. In discordant couples where the man is positive, sperm washing significantly reduces viral transmission risk to the uninfected female partner over unprotected intercourse. Positive women do not necessarily need specialised fertility treatment but should be monitored closely during pregnancy to minimise MCT risk.

The epidemiology of preterm labour--why have advances not equated to reduced incidence?

The major burden of preterm birth is in the developing world, where most of the increasing death and morbidity is secondary to infectious diseases such as malaria, HIV, tuberculosis, bacterial vaginosis and intestinal parasites. In some developing countries, the growth of medical care has outstripped the growth of preventive public health, with an associated increase in iatrogenic preterm births. In developed countries, more than one-third of preterm births are medically indicated because of conditions such as fulminating pre-eclampsia or severe intrauterine growth restriction. Neither of these conditions is currently preventable. One in five preterm births is associated with multiple pregnancy, and these have been greatly increased by assisted reproduction techniques. The use of tocolytics has proved disappointing perhaps because inflammation rather than spontaneous uterine activity is increasingly recognised as the final common pathway. Inappropriate antibiotics used late in pregnancy are ineffective and may have adverse effects. Currently, the most promising interventions are public health related and include reducing the transmission of communicable diseases, improvements in the management of diabetes and reduction in harmful behaviours such as smoking and drug abuse.

Serotonin transporter protein polymorphism and harm avoidance personality in migraine without aura.

OBJECTIVE: To investigate polymorphisms in the serotonin transporter protein gene and harm avoidance personality dimension in patients with migraine without aura (MWOA). BACKGROUND: The serotonin transporter protein is a key modulator of serotonergic synaptic neurotransmission. Two polymorphic regions of the gene for serotonin transporter protein have been found, and are associated with variations in the functional activity of serotonin caused by differing transcriptional efficiency. The harm avoidance (HA) personality trait may also be heritable and associated with altered serotonergic neurotransmitter activity. DESIGN: We amplified the polymorphism in the promoter of serotonin transporter protein (5-HTTLPR) and the variable number of tandem repeats polymorphism within intron 2 (VNTR) using the polymerase chain reaction and performed genotype polymorphism analyses in 97 patients with MWOA and 100 healthy controls. We investigated serotonin-related personality traits by evaluating the HA personality dimension using a tridimensional questionnaire. RESULTS: The genotype frequencies and allele distributions of 5-HTTLPR did not differ between patients with MWOA and controls. The VNTR genotype STin2.12/STin2.12 was significantly more common in patients with MWOA (90%) than in controls (77%; P= .017). Patients with MWOA also had HA scores (21.9 +/- 6.4) significantly higher than those of controls (16.3 +/- 6.1; P < .001). CONCLUSIONS: Serotonergic activity might be involved in the development of MWOA and VNTR of serotonin transporter gene might be one of the genetically contributing factors.

The effect of temperament and character on response to selective serotonin reuptake inhibitors in panic disorder.

OBJECTIVE: In this prospective study, temperament and character were evaluated in patients with panic disorder (PD), before 1 year of medication therapy, to verify whether these factors influenced the outcome of treatment. METHOD: Seventy-one PD patients were evaluated with the SCID-IV, the Temperament and Character Inventory (TCI), the SCL-90, the Ham-A and the Ham-D. Patients were treated with pharmacotherapy and were evaluated monthly over 1 year. RESULTS: Before treatment, non-remitted patients showed higher levels of harm avoidance (HA) and lower levels of persistence (P), self-directedness (SD) and cooperativeness (C), whereas remitted patients showed only higher levels of HA. After controlling the effect of the confounding variables, the likelihood to achieve remission was positively related to SD score (OR = 1.12; P = 0.002), particularly 'self-acceptance' SD dimension (OR = 1.30; P = 0.02). CONCLUSIONS: Our data suggest that in PD: i) the evaluation of personality, using the Cloninger's model, confirms the presence of personality pathology as one predictor of non-response to treatment; ii) in patients with low SD a combination of medication and cognitive-behaviour therapy should be the most effective treatment.

Tryptophan hydroxylase 1 gene haplotypes modify the effect of a hostile childhood environment on adulthood harm avoidance.

We conducted a series of tests to determine whether there is any association between tryptophan hydroxylase 1 (TPH1) and temperament in adulthood. In addition to testing for main effects, we investigated whether TPH1 gene variation modifies the influence of childhood environment on temperament in adulthood. The subjects were 341 healthy adults whose childhood environment was assessed by their mothers in 1980 and who self-rated their temperaments twice, in 1997 and 2001. We found no association between the TPH1 gene and temperament; however, among women, the TPH1 gene modified a relationship between adverse childhood environment and harm avoidance in adulthood. This finding was confirmed in the same sample in another test setting 4 years later. The presence of the A/A haplotype of the TPH1 intron 7 A218A and A779C polymorphism predicted a high level of adulthood harm avoidance in the presence of a hostile childhood environment as defined in terms of emotional rejection, maternal neglect and harsh and inconsistent discipline. In addition, the findings suggest a gene-environment correlation for novelty seeking in men.

[Impact of influenza epidemics and efficacy of vaccination among geriatric inpatients].

To determine the impact of influenza epidemics among geriatric inpatients and to monitor the clinical efficacy of influenza vaccination, the influenza infection rate in non-vaccinated inpatients was determined serologically and the incidence of febrile episodes and death were compared between the vaccinees and non-vaccinees hospitalized in the referred hospital from January through September, 1995. Three influenza subtypes, influenza A/H1N1, A/H3N2, and B, were endemic simultaneously from January to March in 1995. The pattern of incidence of febrile episodes varied for each ward. A total of 123 non-vaccinated inpatients were tested for elevation of serum hemagglutination inhibition titer to the three subtypes of influenza virus. Of these, 58 (47.2%) patients were infected with at least one of the influenza viruses during the epidemic of 1995. No patient with pre-existing HI titer over 128X was infected with any of three types of influenza, indicating that HI titer over 128X is the protective level. The febrile episode frequency was significantly higher in the non-vaccinees than in the vaccinees (49.6% vs. 32.6%), but it was quite comparable in the two groups after the influenza epidemic (34.9% vs. 35.8%). The number of observed deaths from January to September of 1995 was 4 (4.9%) in the vaccinee group and 12 (9.8%) in the non-vaccinee group. These results suggest that influenza epidemics have a striking impact on geriatric inpatients and that influenza vaccination has significant efficacy for the reduction of harmful events associated with influenza infection.
