Do Homicide Perpetrators Have Higher Rates of Delayed-Suicide Than the Other Offenders? Data from a Sample of the Inmate Population in Italy.

Homicide-suicide can be defined as homicide followed by the suicide of the perpetrator shortly afterward. In the so-called "homicide-delayed suicide", homicide and suicide occur but within a wide and not strictly defined timeframe. This study analyzes data concerning the suicide of 667 inmates in Italy between 2002 and 2015, considering homicide perpetrators compared to all offenders. The analyses revealed that inmates who had committed homicide were more likely to commit suicide (71% versus 45%; χ2 = 10.952, p = 0.001) and the odds of suicide increase concerning 1.58 times among homicide perpetrators. The time-to-suicide interval after homicide ranges between 0 to 9.125 days (mean = 1.687,9; SD = 2.303,1). Moreover, the intimate-homicide offenders who committed suicide had a significantly shorter survival time after the offense than did the other non-intimate offenders who died by suicide (t test, t = -3.56, df = 90, p = 0.001). The link between homicide and higher suicide risk in homicide perpetrators should be highlighted because of all the homicide offenders passing through the criminal justice system. Superior knowledge about the path of homicide-delayed suicide will be of particular use to professionals in evaluating and treating homicide inmates.

Health Care Professionals' Knowledge of Stalking Perpetrators, Victims, Behaviors, and Coping Strategies: A Preliminary Study among Italian Hospitals.

The aim of this study was to investigate health care professionals' level of in-depth understanding about the various types and characteristics of stalking. In particular, the study examines knowledge on the characteristics of stalkers and their victims, acted behaviors, and coping strategies used to stop the harassment. The data were collected by means of an ad hoc questionnaire. The sample comprised 210 participants working in local health units in Turin, a large city located in the northern part of Italy. The majority were women (160, 76.2%). The participants were aged 20-64 years, and the mean age was 41.63 years (SD = 11.18). The majority of participants were psychologists (99, 47.1%), 31 (14.8%) were nurses, 31 (14.8%) had an unspecified medical profession, 29 (13.8%) were psychiatrists, and 20 (9.5%) were general practitioners. According to the findings, interventions with male victims of stalking, especially when the stalker is a woman, require attention in particular. Underestimating the stalking experience is a risk, so health care professionals in their interventions must explain to the men the emotive and physical consequences of the victimization. Moreover, in suggesting coping strategies, health care professionals must consider the victim's fear of reporting the incident not only to law enforcement authorities but also to family and friends. The findings showed that health care professionals need a better understanding of the stalking phenomenon. Education courses are a valuable tool to identify characteristics of the phenomenon, validate existing knowledge, and decrease the level of missing information to develop the skills needed to take appropriate action in cases of stalking.

From Traumatic Childhood to Cocaine Abuse: The Critical Function of the Immune System.

BACKGROUND: Experiencing traumatic childhood is a risk factor for developing substance use disorder, but the mechanisms that underlie this relationship have not been determined. Adverse childhood experiences affect the immune system, and the immune system mediates the effects of psychostimulants. However, whether this system is involved in the etiology of substance use disorder in individuals who have experienced early life stress is unknown. METHODS: In this study, we performed a series of ex vivo and in vivo experiments in mice and humans to define the function of the immune system in the early life stress-induced susceptibility to the neurobehavioral effects of cocaine. RESULTS: We provide evidence that exposure to social stress at an early age permanently sensitizes the peripheral (splenocytes) and brain (microglia) immune responses to cocaine in mice. In the brain, microglial activation in the ventral tegmental area of social-stress mice was associated with functional alterations in dopaminergic neurotransmission, as measured by whole-cell voltage clamp recordings in dopamine neurons. Notably, preventing immune activation during the social-stress exposure reverted the effects of dopamine in the ventral tegmental area and the cocaine-induced behavioral phenotype to control levels. In humans, cocaine modulated toll-like receptor 4-mediated innate immunity, an effect that was enhanced in those addicted to cocaine who had experienced a difficult childhood. CONCLUSIONS: Collectively, our findings demonstrate that sensitization to cocaine in early life-stressed individuals involves brain and peripheral immune responses and that this mechanism is shared between mice and humans.

Murder followed by suicide: filicide-suicide mothers in Italy from 1992 to 2010.

The international literature shows that in 40-50% of the cases, homicides-suicides involving children under the age of 10 are committed by mothers. Here, we report some results on homicides-suicides, in the mother-child relationship, occurred in Italy between 1992 and 2010. We examined 36 cases of filicide-suicide mothers by consulting the archives of RAI, daily newspapers, and the ANSA news agency. We focused on: mothers and children's age, place of residence, date and place of the murder, number and sex of the murdered children, and modality of the homicide-suicide. At the time of the homicide-suicide, the average age of mothers was 35.4. The number of children killed by each mother was one, except in seven cases. All the women had underestimated psychopathological disorders and only six women were regularly treated. The dynamics and characteristics of the events were much more similar to suicides than homicides, so we can consider them as "extensive suicides."

Stalking of psychiatrists: psychopathological characteristics and gender differences in an Italian sample.

Research has indicated that medical doctors and paramedics are at higher risk of being stalked than the general population. In particular, mental health care professionals alone represent one third of the victims of harassment. Because of the lack of studies in this specific sector, especially in Italy, in this study, we examined the stalking of psychiatrists by their patients, considering gender differences and the incidence of stalking in private practice and public mental health clinics in Rome. We found that the rate of stalking in private mental health settings is higher than that in public settings and that the perpetrators of stalking are mainly women who mostly target mental health professionals working in private practice. Implications of the findings are noted and discussed.

[Stalking: clinical and criminological considerations through the results of a research contribution]. / Stalking: considerazioni clinico-criminologiche tramite i risultati di un contributo di ricerca.

Among the extensive results supplied by the psychiatric literature on the subject of stalking, few studies focus on the analysis of persecutory behaviors carried out against mental health professionals, who also identified as one of the most affected sample of victims. Particularly, for studies conducted in this way, further examination requires differentiation according to gender type into the social and personal characteristics of the authors' behavior patterns displayed towards the victims. Aim. To obtaine results by an epidemiological survey conducted in public and private psychiatric care structures in the city of Rome, to assess the incidence of the phenomenon as well as gender differences in behavior patterns practised out by the author for the two sample considered. Methods. Administration of a questionnaire to a sample make up by psychiatrists working in out-patient services for the Departments of Mental Health (ASL) of Rome and to a sample of psychiatrists who practise their professional activity in the private sector. Results. Regarding the incidence of the phenomenon, an increased presence has been found in private mental health care settings in comparison to the public service; regarding to the distribution of the phenomenon according to the sexual identity of the authors among the two samples analyzed, a statistical prevalence of female authors has been found in the sample of private sector. Discussion. The health's professionals, so much liable of victimization, are poorly formed on the phenomenon. So it's urgent to operate with integrated approaches (informative trainings; strengthening of administrative and clinical policies of the profession; multidimensional assessment).

Early trauma and adult obesity: is psychological dysfunction the mediating mechanism?

Several studies have shown that physical and/or sexual abuse during childhood may lead to the development of obesity later in life. Despite these consistent findings, the mechanism for the increased risk of obesity following developmental trauma is unknown. It has been suggested that psychological dysfunction, including the presence of disordered eating behavior, may account for the added risk of adult obesity. To test this hypothesis, we analyzed the prevalence and severity of different types of early traumatic life events, assessed the presence of co-existing psychiatric disorders and measured adult attachment style in a sample of 200 subjects including non-obese healthy volunteers and obese participants undergoing a psychiatric assessment to determine suitability for bariatric surgery. Participants who scored higher on a scale measuring the severity of traumatic events experienced during the first 15years of their lives were more likely to be obese at the time of testing. The exclusion of the participants who experienced physical and/or sexual abuse did not change the results of statistical analysis. Severity of early trauma remained a significant predictor of adult obesity when the influence of psychiatric diagnosis and anxious attachment was taken into account. These findings suggest that: (1) not only sexual or physical abuse but also less severe forms of early-life stress are linked to the development of obesity later in life; and (2) psychological dysfunction is not the only mechanism mediating the elevated risk of obesity in persons exposed to early-life trauma.

Apolipoprotein A-I/apolipoprotein B ratio and aggression in violent and nonviolent young adult males.

Epidemiological, clinical, and experimental studies have linked low or lowered cholesterol levels to aggressive behavior. However, no study has measured the relationship between aggression and apolipoprotein A-I/apolipoprotein B ratio, a robust indicator of cardiac risk. Plasma levels of total cholesterol, HDL-C, LDL-C, triglycerides, apolipoprotein A-I, and apolipoprotein B were measured and correlated with Aggression Questionnaire ratings in 20 young adult males with personality disorders and/or a high propensity toward aggressive behavior and in 40 control subjects. Compared with the control subjects, the subjects in the aggressive group had lower levels of apo A-I and a lower apo A-I/apo B ratio. Whereas in the control subjects, higher levels of aggression were correlated with lower levels of atherogenic lipoproteins (LDL-C and apo B), in the aggressive subjects higher levels of aggression were correlated with lower levels of anti-atherogenic lipoproteins (HDL-C and apo A-I) and higher levels of LDL-C. The results of this study confirm the existence of a relationship between blood lipids and aggressive behavior in young adult males and suggest that the apo A-I/apo B ratio might be an additional marker in the search for biological correlates of increased risk of violence.

The relationship between anger and depression in a clinical sample of young men: the role of insecure attachment.

BACKGROUND: Even though the relevance of insecure attachment in the etiology of dysfunctional anger is indicated by a number of findings, few studies have examined the relationship between anger and depression from the perspective of attachment theory. METHODS: Self-reported measures of trait anger, depression, and adult attachment style were simultaneously administered to 87 young men with clinically significant depressive symptoms. RESULTS: Higher levels of trait anger were associated with an insecure style of attachment. Such an association remained significant after controlling for the severity of depressive symptoms. In a multiple regression model, both a measure of anxious attachment and a measure of avoidant attachment emerged as independent predictors of trait anger. LIMITATIONS: The study was cross-sectional and the sample did not include women. CONCLUSIONS: Insecure attachment is a useful predictor of anger experience among patients with depressive symptoms.
