D Kimberley Molina, Veronica M Hargrove
Determining the manner of death in medicolegal death investigations can be difficult. The investigator relies on many facets of death investigation, including the circumstances of death and autopsy examination. A study was designed to analyze whether the intoxication status of the decedent could be used as another tool in death investigations. The intoxication status of violent (nonoverdose or poisoning) suicides and homicides was retrospectively reviewed and compared. A total of 625 deaths were identified, including 366 suicides and 259 homicides...

AIM: To investigate factors predicting treatment completion and treatment outcome of the Reasoning and Rehabilitation Mental Health Programme (R&R2MHP) cognitive skills programme for mentally disordered offenders. METHODS: Secondary analysis of data previously obtained from 97 male patients who were sectioned and detained under the United Kingdom Mental Health Act in low, medium and high security hospitals and who had completed R&R2MHP. Predictors of treatment completion included background variables and five outcome measures: Four self-reported measures of violent attitudes, social problem-solving skills, reactive anger and locus of control and an objective measure of behaviour on the ward that was completed by staff...

Discrete populations of neurons at multiple levels of the brainstem control rapid eye movement (REM) sleep and the accompanying loss of postural muscle tone, or atonia. The specific contributions of these brainstem cell populations to REM sleep control remains incompletely understood. Here we show in rats that viral vector-based lesions of the ventromedial medulla at a level rostral to the inferior olive (pSOM) produced violent myoclonic twitches and abnormal electromyographic spikes, but not complete loss of tonic atonia, during REM sleep...

Multidimensional family therapy (MDFT) is an established treatment program for youth displaying multiproblem behavior. We examined whether MDFT decreased criminal offending among cannabis abusing adolescents, as compared with individual psychotherapy (IP). In a Western European randomized controlled trial comparing MDFT with IP, a sample of 169 adolescents with a cannabis disorder completed self-reports on criminal offending. Half indicated they had committed one or more criminal offenses in the 90 days before the baseline assessment...

BACKGROUND: Juvenile violent offending is a serious worldwide public health issue. OBJECTIVE: The study examined whether the Structured Assessment of Violence Risk in Youth (SAVRY) can be used to predict violent reoffending in Chinese male juvenile offenders, and to determine which risk/protective domains (items) are associated with violent recidivism. METHODS: A total of 246 male juvenile offenders were recruited. SAVRY domains were scored by trained raters based on file review and interviews with participants and their legal guardians...

Few studies have examined how neighborhood contextual features may influence the food outlet mix. We evaluated the relationship between changes in neighborhood crime and changes in the food environment, namely the relative density of unhealthy (or intermediate) food outlets out of total food outlets, or food swamp score, in Baltimore City from 2000 to 2012, using neighborhood fixed-effects linear regression models. Comparing neighborhoods to themselves over time, each unit increase in crime rate was associated with an increase in the food swamp score (b = 0...

Violent ideations occur more frequently in individuals with mental health problems. They may be of interest in clinical contexts as possible indicators of dangerousness, as corollaries of mental health problems, as candidate treatment targets and as potentially playing a role in perpetuation or onset of symptoms. In spite of their relevance to mental health, some fundamental questions about their place within the broader landscape of mental health problems remain unanswered. To provide a basic characterisation of the relations between violent ideations and dimensions of mental health and provide a foundation for future research in this area we factor analysed a measure of violent ideations and an omnibus measure of mental health dimensions in a normative sample of 1306 youth (at age 17)...

How populations and communities reassemble following disturbances are affected by a number of factors, with the arrival order of founding populations often having a profound influence on later populations and community structure. Kasatochi Island is a small volcano located in the central Aleutian archipelago that erupted violently August 8, 2008, sterilizing the island of avian biodiversity. Prior to the eruption, Kasatochi was the center of abundance for breeding seabirds in the central Aleutian Islands and supported several breeding pairs of peregrine falcons (Falco peregrinus)...

BACKGROUND: Many women experience psychological trauma during birth. A traumatic birth can impact on postnatal mental health and family relationships. It is important to understand how interpersonal factors influence women's experience of trauma in order to inform the development of care that promotes optimal psychosocial outcomes. METHODS: As part of a large mixed methods study, 748 women completed an online survey and answered the question 'describe the birth trauma experience, and what you found traumatising'...

INTRODUCTION: The tensions between risk and benefit in research are particularly evident in studies about intimate partner violence. Recalling and relating traumatic experiences may deepen posttraumatic stress or relieve the burden of terrible events long borne in secret. In this article, we examine the effects of study participation in a longitudinal investigation of intimate partner violence using both qualitative and quantitative data. METHOD: Researchers enrolled 200 women in moderately violent intimate relationships and asked them to report about their relationships every day for 12 weeks...

Bullying is defined as systematic exposure to humiliation as well as hostile and violent behaviors against one or more individuals. These behaviors are a serious, growing problem, which affects a significant proportion of health care professionals. To support the hospital's risk management policy, a cross-sectional study was undertaken to determine the prevalence of bullying in this institution and identify the determinants of bullying. Bullying was measured using the Negative Acts Questionnaire-Revised, Portuguese version (NAQ-R), a self-administered tool...

BACKGROUND: Rates of violence perpetrated by patients toward health care workers are known to be higher in psychiatry than in other fields. Objective standardized reports of violent incidents may clarify this phenomenon. OBJECTIVE: The purpose of this study was to assess the characteristics of patient violence, as evident from objective reports. STUDY DESIGN: In this retrospective chart review study, conducted at a large mental health hospital in Israel between 2013 and 2015, reports of violent incidents perpetrated by people diagnosed with mental health problems against health care workers of the hospital were reviewed...

Witnesses to violent crimes are often alcohol intoxicated, but few studies have investigated the impact of alcohol on witness reports. This study investigated how alcohol intoxication and time of interview affected reports of intimate partner violence (IPV). One hundred thirty six healthy men (N = 66) and women (N = 70) were randomized to an alcohol group (0.8g/kg for men, 0.75g/kg for women) (N = 70) or control group (N = 66), given juice. Participants consumed drinks in a laboratory setting before they witnessed an IPV scenario...

Determinants of species diversity in microbial ecosystems remain poorly understood. Bacteriophages are believed to increase the diversity by the virtue of Kill-the-Winner infection bias preventing the fastest growing organism from taking over the community. Phage-bacterial ecosystems are traditionally described in terms of the static equilibrium state of Lotka-Volterra equations in which bacterial growth is exactly balanced by losses due to phage predation. Here we consider a more dynamic scenario in which phage infections give rise to abrupt and severe collapses of bacterial populations whenever they become sufficiently large...

OBJECTIVE: To evaluate the effects of a randomized controlled intervention on the incidence of patient-to-worker (Type II) violence and related injury in hospitals. METHODS: Forty-one units across seven hospitals were randomized into intervention (n = 21) and control (n = 20) groups. Intervention units received unit-level violence data to facilitate development of an action plan for violence prevention; no data were presented to control units. Main outcomes were rates of violent events and injuries across study groups over time...

TBI is a nondegenerative, noncongenital insult to the brain from an external mechanical force; for instance a violent blow in a car accident. It is a complex injury with a broad spectrum of symptoms and has become a major cause of death and disability in addition to being a burden on public health and societies worldwide. As such, finding a therapy for TBI has become a major health concern for many countries, which has led to the emergence of many monotherapies that have shown promising effects in animal models of TBI, but have not yet proven any significant efficacy in clinical trials...

Both the psychological and criminological fields have long hypothesized the mechanisms that influence desistance from violent offending, but few studies have focused on violent females. This study identifies patterns of violent behavior across 7 years among 172 females and 172 matched males ages 15-24, testing if heterogeneity in violent offending is linked to (a) developmental change in impulse control and (b) attainment of adult milestones. Fewer females persist in violence (25%) than males (46%); 19% of males increase in violent behavior...

This report compares the effects (concurrent and lagged) of the anticipated rewards and costs of violent crime on engagement in severe violence in a sample of male juvenile offenders (N = 1,170; 42.1% black, 34.0% Hispanic, 19.2% white, and 4.6% other; ages 14-18 at baseline). Anticipated rewards (social approval, thrill) are more predictive of concurrent severe violence than are anticipated costs (social disapproval, risk of punishment). The analysis finds no evidence that perceptions of the rewards and costs of violent crime influence engagement in severe violence 6 months later...

Using a cohort of 310 low-income male adolescents living in an urban community and followed prospectively from 18 months through adolescence (ages 15-18 years), the current study examined whether individual, family, and community risk factors from ages 18 to 42 months were associated with adolescents' violent behavior, as indexed by juvenile petitions. Results of multivariate analyses indicated that although family income was the only factor to discriminate those with no arrest record from those with nonviolent arrests, rejecting parenting, child oppositional behavior, emotion regulation, and minority status during the toddler period contributed unique variance in distinguishing male adolescents arrested for violent behavior compared to those never arrested and those arrested for nonviolent behavior...
