High CSF-insulin in violent suicide attempters

Several studies have investigated a connection between diabetes and major depressive disorder (MDD). Whether these associations are mediated by changes in insulin is not known. Insulin seems to play a role in violent behaviour. To further elucidate the role of insulin in MDD and violent, aggressive, or impulsive behaviour, we measured insulin in cerebrospinal fluid (CSF) in 74 patients with a recent suicide attempt. Patients were divided into those with and without MDD, and they were also subgrouped by whether the suicide attempt was considered to be violent or not. It was found that patients with a violent suicide attempt had significantly higher CSF-insulin (5.9+/-1.0 pmol/l) than those with a nonviolent attempt (5.3+/-0.7 pmol/l). In contrast, there were no significant differences in CSF-insulin between patients with MDD and patients without. Our findings support the hypothesis that CSF-insulin is involved in violent behaviour, but not connected to MDD as such.

Altered glucose tolerance in women with deliberate self-harm.

Disturbances in glucose metabolism are of importance for violent behaviour in men, but studies in women are lacking. We used the 5h-oral glucose tolerance test (OGTT) in this study of 17 female psychiatric patients, selected for violent behaviour directed against themselves (deliberate self-harm) and 17 healthy controls matched for age and BMI. Following OGTT, patients had higher glucose levels at 30 min (p=0.007) and increased glucagon area under the curve (p=0.011). Since a co-morbid eating disorder might affect results, we as a post-hoc analysis subgrouped the patients and found that the increased glucagon levels only were present in patients with an eating disorder. In contrast, those without an eating disorder showed a significantly lower p-glucose nadir (p=0.015) and unaltered glucagon levels compared to controls. There were no significant differences in insulin and C-peptide levels between patients and controls. We conclude that deliberate self-harm in women may be associated with alterations in carbohydrate metabolism in certain groups. Eating disorder is a confounding factor.

The Psychobiology of Aggressive Behaviour

Among psychiatric illnesses, genetically determined disorders usually have an early onset and a severe and complicated course. Gene-environmental interaction is of importance for aggressive impulsive behaviour. For example, alcoholism type II has a high family loading, a severe course, and is often associated with antisocial behaviour. In order to gain further understanding of aggressive and impulsive behaviour, genes determining serotonin metabolism, neurosteroids and carbohydrate metabolism should be of interest to investigate. Furthermore, modern brain-imaging studies will reveal the site of action of aggressiveness and impulsivity. Within brain regions of interest, biological studies will promote our knowledge of this deleterious behaviour.

Individuals’ experiences with Brief Admission during the implementation of the Brief Admission Skåne RCT, a qualitative study

Abstract Background: Brief admission (BA) is an adjunctive treatment option for individuals with self-harming behavior, having traits of borderline personality disorder (BPD). It is offered alongside outpatient psychotherapy for the purpose of strengthening autonomy, self-reflection and self-care and to increase the likelihood of being able to stay in therapy by avoiding lengthy inpatient hospitalizations. Aims: To investigate participants’ experiences with BA during the pilot phase of the Brief Admission Skåne Randomized Controlled Trial (BASRCT), in order to detect possible strengths and limitations of the intervention and gain knowledge to facilitate implementation of BA at other treatment centers. Method: Eight participants randomized to BA were interviewed to obtain their experience of BA, or alternatively their reasons for choosing not to use BA. Thematic analysis was conducted upon their transcribed interviews. Results: Reported as most helpful by the participants was the structure/routines at the ward and the positive attitudes from the staff. However, some individuals reported problems with perceived negative attitudes from the staff administering BA and negative rumination about themselves. The reported reasons to request BA were: preventing urges to self-harm from escalating; ending isolation; preventing longer admissions and forced admission; feelings of emotional exhaustion, and the need for rest and support in re-creating a daily routine. Reasons for not requesting BA were fear of rejection, questioning the method; presumed room shortage; difficulties in deciding whether one’s problems are serious enough; experiencing the situation to be too clinically acute. Conclusion: The results from this study indicated the importance of repeated staff education on all aspects of BA when it is being newly implemented, as well as the importance of working with attitudes of staff delivering BA. These were the key ingredients in making BA implementation successful. Our findings may be of value to other treatment centers implementing BA for the first time. Trial registration: NCT02985047.

Deliberate self-harm behavior among young violent offenders

Deliberate self-harm behavior (DSH) can have profound effects on a person’s quality of life, and challenges the health care system. Even though DSH has been associated with aggressive interpersonal behaviors, the knowledge on DSH in persons exhibiting such behaviors is scarce. This study aims to (1) specify the prevalence and character of DSH, (2) identify clinical, neurocognitive, psychosocial, and criminological characteristics associated with DSH, and (3) determine predictors of DSH among young violent offenders. Data were collected from a nationally representative cohort of 270 male violent offenders, 18–25 years old, imprisoned in Sweden. Participants were interviewed and investigated neuropsychologically, and their files were reviewed for psychosocial background, criminal history, mental disorders, lifetime aggressive antisocial behaviors, and DSH. A total of 62 offenders (23%) had engaged in DSH at some point during their lifetime, many on repeated occasions, yet without suicidal intent. DSH was significantly associated with attention deficit hyperactivity disorder, mood disorders, anxiety disorders, various substance use disorders, being bullied at school, and repeated exposure to violence at home during childhood. Mood disorders, anxiety disorders, and being bullied at school remained significant predictors of DSH in a total regression model. Violent offenders direct aggressive behaviors not only toward other people, but also toward themselves. Thus, DSH must be assessed and prevented in correctional institutions as early as possible, and more knowledge is needed of the function of DSH among offenders.

Coping and suicide risk in high risk psychiatric patients

Abstract Background: A dysfunctional use of coping strategies has repeatedly been linked to suicidal behaviour in non-psychiatric populations. However, data regarding association between coping strategies and suicidal behaviour in psychiatric populations are limited. Aims: The aim of the study was to investigate the possible relationship between self-reported suicide risk, suicidal ideation and coping strategies in three psychiatric cohorts. Method: Three cohorts of psychiatric patients were involved in the study; recent suicide attempters (n = 55), suicide attempters at follow-up 12 years after a suicide attempt (n = 38) and patients with ongoing depression without attempted suicide (n = 72). Patients filled in the self-rating version of The Suicide Assessment Scale (SUAS-S) from which items no. 17–20 addressing current suicidal ideation were extracted. To investigate coping strategies, the Coping Orientation of Problem Experience Inventory (COPE) was used. Results: In all cohorts, regression analyses showed that only avoidant coping was significantly correlated with the scores of SUAS-S adjusted for covariates. The items no. 17–20 correlated significantly to avoidant coping but not with other coping strategies in all cohorts. Conclusion: The results of this study indicate that among coping strategies only avoidant coping may be associated with suicide risk in psychiatric patients independently of history of attempted suicide.
