Social-cognitive theories of aggression postulate that individuals who perpetrate aggression are likely to have high levels of maladaptive cognitive schemas that increase risk for aggression. Indeed, recent research has begun to examine whether early maladaptive schemas may increase the risk for aggression. However, no known research has examined this among individuals in substance use treatment, despite aggression and early maladaptive schemas being more prevalent among individuals with a substance use disorder than the general population. Toward this end, we examined the relationship between early maladaptive schemas and aggression in men in a residential substance use treatment facility (N = 106). Utilizing pre-existing patient records, results demonstrated unique associations between early maladaptive schema domains and aggression depending on the type of aggression and schema domain examined, even after controlling for substance use, antisocial personality, age, and education. The Impaired Limits domain was positively associated with verbal aggression, aggressive attitude, and overall aggression, whereas the Disconnection and Rejection domain was positively associated with physical aggression. These findings are consistent with social-cognitive models of aggression and advance our understanding of how early maladaptive schemas may influence aggression. The implications of these findings for future research are discussed. PMID:25897180

This review focuses on the factors that now influence our treatment strategies designed to increase the pool of patients with colorectal liver metastases for whom curative treatment may be possible. These strategies include improved preoperative staging techniques, new standards for surgical resection, novel surgical strategies, the application of modern systemic chemotherapy in a neoadjuvant setting, an emerging role for ablative therapies and an emphasis on the collaborative, a reappraisal of staging advanced disease, multidisciplinary management, and defining the role of the patient in managing their disease. It is now clear that an aggressive multi-disciplinary approach to the management of this problem will lead to nearly one third of these patients being considered for treatment that even if not achieving complete cure, offers significant long-term survival.

Identification and treatment of aggressive thyroid cancers. Part 2: risk assessment and treatment.

PubMed

Sturgeon, Cord; Angelos, Peter

2006-04-01

Most thyroid cancers are slow-growing, easily treatable tumors with an excellent prognosis after surgical resection and targeted medical therapy. Unfortunately, 10% to 15% of thyroid cancers exhibit aggressive behavior and do not follow an indolent course. Approximately one-third of patients with differentiated thyroid cancers will have tumor recurrences. Distant metastases are present in about 20% of patients with recurrent cancer. Approximately half of patients with distant metastases die within 5 years. The loss of the ability to concentrate radio-iodine and produce thyroglobulin is a sign of dedifferentiation, which occurs in about 30% of patients with persistent or recurrent thyroid cancer. Dedifferentiation is associated with poorer responses to conventional therapy and difficulty monitoring tumor burden. Clinicians must identify tumors with more aggressive biology and treat them accordingly with more aggressive regimens. Part 1 of this two-part article, which appeared in March, described in detail the distinct types of thyroid cancer, as well as risk factors, outcomes, treatment, and prognostic factors, with a focus on thyroid cancers of follicular cell origin. Part 2 covers risk assessment and staging, findings that suggest the presence of aggressive tumors, recurrent/metastatic disease, and treatment with chemotherapy and external-beam radiotherapy. Experimental treatments utilizing molecular targets, redifferentiation agents, and gene therapy are covered briefly as well.

Children often respond to aggression by peers with assertive bids or aggressive retaliation. Little is known, however, about whether and how children coordinate these strategies across different types of provocation. The present study examined endorsement of aggressive and assertive responses to hypothetical physical, relational, and verbal provocation in a sample of lower-income children (N = 402, M age = 10.21, SD = 1.46). Latent-profile analysis revealed 3-class models for both aggression and assertion, each reflecting low, moderate, and high levels of endorsement. There was no association between children's reported use of aggression and assertion. For example, children who endorsed high levels of aggression were equally likely to be classified as low, moderate, or high on assertive responding. For both assertion and aggression, parental ratings of children's externalizing behavior and social skills differed across the low and high groups. No such differences were found between the low and moderate groups, despite the latter groups endorsing markedly higher levels of assertive and aggressive responses. This pattern of findings may be due, in part, to the situation specificity of children's responding. Our findings hint at the complexity of children's behavioral repertoires and contribute to a growing literature that suggests the need for intervention models that consider both social skills and social situations.

Aggressive active case detection: a malaria control strategy based on the Brazilian model.

PubMed

Macauley, Cameron

2005-02-01

Since 1996, the Brazilian Ministry of Health has adopted a malaria control strategy known as aggressive active case detection (AACD) in which most or all members of every community are tested and treated for malaria on a monthly basis. The strategy attempts to identify and treat cases of asymptomatic malaria, which, if untreated, continue to transmit the infection. Malaria remains uncontrolled because almost all health care systems in the world rely on passive case detection: the treatment of only symptomatic cases of malaria. Research has shown conclusively that asymptomatic cases exist in any population where malaria transmission is stable and incidence is high: therefore passive case detection simply will not succeed in breaking the cycle of transmission. Numerous case studies show that malaria has been successfully controlled on a regional or national level by mass blood surveys. AACD is an effective malaria control strategy if used in conjunction with other methods, especially when (1) an effective treatment exists, (2) influx of potential carriers of the infection can be monitored, and (3) people are inclined to cooperate with monthly blood testing. AACD requires access to rapid diagnostic tests (RDTs), microscopy supplies, extensive human resources, and prompt, affordable, and effective treatment. AACD is compared to PCD in terms of clinical efficacy and cost effectiveness in a case study of malaria in the Brazilian Yanomami Indians. Where it is feasible, AACD could drastically reduce the incidence of malaria and should be an integral part of the World Health Organization's Roll Back Malaria strategy.

Impulsivity and Aggression in Schizophrenia: A Neural Circuitry Perspective with Implications for Treatment

PubMed Central

Hoptman, Matthew J.

2015-01-01

Elevations of impulsive behavior have been observed in a number of serious mental illnesses. These phenomena can lead to harmful behaviors, including violence, and thus represent a serious public health concern. Such violence is often a reason for psychiatric hospitalization, and it often leads to prolonged hospital stays, suffering by patients and their victims, and increased stigmatization. Despite the attention paid to violence, little is understood about its neural basis in schizophrenia. On a psychological level, aggression in schizophrenia has been primarily attributed to psychotic symptoms, desires for instrumental gain, or impulsive responses to perceived personal slights. Often multiple attributions can coexist during a single aggressive incident. In this review, I will discuss the neural circuitry associated with impulsivity and aggression in schizophrenia, with an emphasis on implications for treatment. Impulsivity appears to account for a great deal of aggression in schizophrenia, especially in inpatient settings. Urgency, defined as impulsivity in the context of strong emotion, is the primary focus of this article. It is elevated in several psychiatric disorders, and in schizophrenia, it has been related to aggression. Many studies have implicated dysfunctional frontotemporal circuitry in impulsivity and aggression in schizophrenia, and pharmacological treatments may act via that circuitry to reduce urgency and aggressive behaviors, but more mechanistic studies are critically needed. Recent studies point toward manipulable neurobehavioral targets and suggest that cognitive, pharmacological, neuromodulatory, and neurofeedback treatment approaches can be developed to ameliorate urgency and aggression in schizophrenia. It is hoped that these approaches will improve treatment efficacy. PMID:25900066

A Positive Behavioral Approach for Aggression in Forensic Psychiatric Settings.

Tolisano, Peter; Sondik, Tracey M; Dike, Charles C

2017-03-01

Aggression toward self and others by complex patients admitted to forensic psychiatric settings is a relatively common yet extremely difficult behavior to treat. Traditional interventions in forensic inpatient settings have historically emphasized control and management over treatment. Research over the past several years has demonstrated the value of behavioral and psychosocial treatment interventions to reduce aggression and to increase prosocial skill development in inpatient forensic population. Positive behavioral support (PBS) offers a comprehensive approach that incorporates the science of applied behavioral analysis (ABA) in support of patients with challenging behaviors, including aggression and violence. In this article, we describe a PBS model to treat aggression in forensic settings. PBS includes a comprehensive functional assessment, along with four basic elements: ecological strategies, positive programming, focused support strategies, and reactive strategies. Other key components are described, including data collection, staff training, fidelity checks to ensure correct implementation of the plan, and ongoing monitoring and revision of PBS strategies, according to treatment outcomes. Finally, a behavioral consultation team approach within the inpatient forensic setting is recommended, led by an assigned doctoral-level psychologist with specialized knowledge and training in behavioral methods. The behavioral consultation team works directly with the unit treatment team and the identified patient to develop, implement, and track a plan that may extend over several weeks to several months including transition into the community. PBS can offer a positive systemic impact in forensic inpatient settings, such as providing a nonpharmacologic means to address aggression, reducing the incidences of restraint and seclusion, enhancing staff proficiency in managing challenging patient presentations, and reducing recidivism when used as part of the bridge to

The genetics of aggression: Where are we now?

PubMed

Asherson, Philip; Cormand, Bru

2016-07-01

Aggression, an overt behaviour with the intention to inflict damage, is a physiological trait with important roles throughout evolution, both in defence and predation. However, when expressed in humans in the wrong context, aggression leads to social maladjustment and crime. This special issue is about the genetic and neurobiological basis for aggression. Most of the 12 works presented here have been prepared by members of five international consortia established under the auspice of the FP7 and H2020 programs of the European Union to investigate different aspects of aggression and related behavioural phenotypes, including delineation of subtypes, aetiological mechanisms, neurobiology, neuroimaging, biomarkers, animal models and development and assessment of new treatments. Research on human aggression has largely focused on the societal causes of violent behaviour with relatively little focus on the underlying neuroscientific basis. However, interesting findings are emerging which suggest that by identifying distinct pathways to aggression, better targeting of social, psychological and medical treatments, can lead to improved outcomes for individuals and society. This issue represents a state of the art review of current neurobiological understanding of human aggression and a starting point for concerted efforts to move the field towards the development of new strategies for prevention and treatment. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The relationships between social goals, skills, and strategies and their effect on aggressive behavior among adolescents.

Winstok, Zeev

It is widely accepted that conflict-related goals, skills, and strategies are linked. Yet it is rarely explored how these factors relate to each other and how they jointly promote or inhibit aggressive behaviors. The aim of this study is to provide answers to these questions. Data were derived from a structured questionnaire administered to 660 male and female adolescents of an average age of 14.99 years from two urban schools in northern Israel. Findings show that goals, skills, and strategies that promote or inhibit violence are positively interrelated. Furthermore, negative association was found between violence promoting and inhibiting goals, skills, and strategies. Gender differences were also analyzed. It has been found that boys display aggressive behavior more frequently then girls. Findings also show that the rate of violence promoting goals, skills, and strategies is higher among boys than among girls, whereas that of violence inhibiting ones are higher among girls than among boys. Yet when controlling the effects of goals, skills, and strategies, girls demonstrate aggressive behavior more frequently than boys. These research findings are discussed and conceptualized within the theoretical framework of social adjustment.

To review prevention programs, psychosocial and psychopharmacologic treatments, and service delivery configurations for children and adolescents with maladaptive aggression. To propose a research agenda for disorders of aggression in child and adolescent psychiatry. Recent empirical studies were reviewed using searches of MEDLINE and PsycINFO (text terms: aggression, antisocial, violence, conduct, oppositional, psychosocial treatment, psychopharmacology, and prevention), relevant books, review articles, and bibliographies. Articles met the following criteria: published in an English-language, peer-reviewed journal between 1980 and 2005, included a focus on individuals < 18 years old, and included an outcome measure of relevant significance. Results of 154 randomized, controlled psychosocial treatment trials, 20 controlled psychopharmacology studies, 4 open-label medication studies, and 2 psychopharmacology meta-analyses were reviewed. Prevention programs show promise for reducing future aggression in at-risk populations. Empirical support is available for the effectiveness of multifocused psychosocial treatments in reducing aggression in children and adolescents. Atypical antipsychotics, lithium, divalproex sodium, and stimulants for conduct problems associated with attention-deficit/hyperactivity disorder have empirical support for reducing aggression in selected patient populations. Therapeutic nihilism in the treatment of aggressive children and adolescents with conduct problems is no longer warranted. Multifocused psychosocial interventions given early in life to at-risk children have the most support for effectiveness. However, treatments for children who routinely present to the child psychiatrist with already well-established disorders of aggression are neither robust nor well-established. Further research into maladaptive aggression in referred children and adolescents within and across psychiatric diagnoses is important for the field of child and

Minimally invasive flap surgery and enamel matrix derivative in the treatment of localized aggressive periodontitis: case report.

Localized aggressive periodontitis is a distinct entity of periodontal disease and is characterized by deep vertical bony defects that typically affect the first molars and incisors of young patients. Therapy is usually aimed at reducing the pathogenic microflora through scaling and root planing and the administration of systemic antibiotics. However, conservative periodontal therapy may result in reparative wound healing with limited regeneration of the lost tissues. Periodontal surgery combined with enamel matrix derivative has been introduced as a method to promote regeneration of the lost periodontium and has been studied extensively in the treatment of chronic periodontitis. This case report describes the treatment of a 27-year-old patient displaying severe localized aggressive periodontitis with documented disease progression. After initial therapy consisting of scaling and root planing and systemic administration of amoxicillin and metronidazole, the vertical defects were treated by minimally invasive access flaps combined with application of enamel matrix derivative. Clinical, microbiologic, and radiographic findings are reported for up to 1.5 years after initial therapy, indicating good efficacy of the therapeutic strategy and stability of the treatment outcome.

Toward a nosology of human aggressive behavior.

PubMed

Eichelman, B; Hartwig, A

1993-01-01

General attempts have been made to catalog or categorize research literature on aggressive behavior. In the animal literature this category has been delineated by clearly observed and described patterns of behavior. These include offensive and defensive expressions in animals and the characterization of attack behaviors by typography into defensive and offensive. The human literature is considerably deficient in the description and categorization of human aggressive behavior. Current nosologies offer no utilitarian schema for characterizing violent behavior in clinical populations regarding the typography of the violence, its prediction, or guidance as to its treatment. The generation of databased nosologies may provide a mechanism for the development of research and clinically relevant nosologies based upon cluster analyses of treatment outcomes and behavioral characteristics. This strategy may provide a more effective approach for further research concerning clinical aggressive or destructive behaviors.

Alzheimer's aggression: influences on caregiver coping and resilience.

2011-04-01

This study assessed impact of Alzheimer's patients' aggressive behavior (AD aggression) on caregiver coping strategies (task-, emotion-, and avoidance-focused) and caregiver resilience, and examined whether coping strategy moderated the AD aggression-caregiver resilience relationship. Informal caregivers across Louisiana (N = 419) completed surveys with measures of demographics, AD aggression, caregiver coping strategies, and caregiver resilience. Task-focused coping positively related to resilience. Aggression negatively predicted caregiver resilience. Emotion- and avoidance-focused coping strategies separately interacted with aggression and increased its negative relationship to caregiver resilience. Task-focused coping showed no moderation. Implications for social work professionals are discussed.

Aggressive symptomatology presents across multiple psychiatric, developmental, neurological and behavioral disorders, complicating the diagnosis and treatment of the underlying pathology. Anti-Epileptic Drugs (AEDs) have become an appealing alternative in the treatment of aggression, mood lability and impulsivity in adult and pediatric populations, although few controlled trials have explored their efficacy in treating pediatric populations. This review of the literature synthesizes the available data on ten AEDs—valproate, carbamazepine, oxcarbazepine, phenytoin, lamotrigine, topiramate, levetiracetam, zonisamide, gabapentin and tiagabine—in an attempt to assess evidence for the efficacy of AEDs in the treatment of aggression in pediatric populations. Our review revealed modest evidence that some of the AEDs produced improvement in pediatric aggression, but controlled trials in pediatric bipolar disorder have not been promising. Valproate is the best supported AED for aggression and should be considered as a first line of treatment. When monotherapy is insufficient, combining an AED with either lithium or an atypical anti-psychotic can result in better efficacy. Additionally, our review indicates that medications with predominately GABA-ergic mechanisms of action are not effective in treating aggression, and medications which decrease glutaminergic transmission tended to have more cognitive adverse effects. Agents with multiple mechanisms of action may be more effective. PMID:27713387

This article reports the implementation of Dialectical Behavioral Therapy-Corrections Modified (DBT-CM) for difficult to manage, impulsive and/or aggressive correctional populations. Participants were English-speaking women (n = 18) and men (n = 45) of diverse cultural backgrounds between the ages of 16 and 59 years old retained in state-run prisons in Connecticut. Following consent, and a psychological assessment battery, twice-weekly DBT-CM groups were held over 16 weeks followed by random assignment to DBT coaching or case management condition, with sessions taking place individually for eight weeks. Data analysis. A mixed effects regression model was used to test the hypotheses: participants will show decreased aggression, impulsivity, and psychopathology, as well as improved coping, after completing the DBT-CM groups; and will show greater reduction in targeted behaviors than those receiving case management at the six month and 12 month follow-up assessment periods. Significant reduction in targeted behavior was found from baseline to following the 16 week DBT-CM skills treatment groups. Both case management and DBT coaching were significant at 12 month follow-up. A significant difference was found for adult men and women. The study supports the value of DBT-CM for management of aggressive behaviors in prison settings. (c) 2009 John Wiley & Sons, Ltd.

Behavioral and cognitive-behavioral strategies and a broad range of group, family, couples, and milieu treatment approaches have been developed for the psychotherapy of aggressive and violent patients. These methods have been carried out in diverse settings ranging from hospitals and prisons to individual outpatient practices and have been applied across diverse populations including adults with mental retardation, dementia, and brain injury; children with attention deficit and conduct disorders and autism; recurrent violent offenders with antisocial personality disorder; and individuals with chronic psychotic disorders, mood disorders, or medical illnesses such as hypertension. Bridging these different strategies are the underlying principles of psychotherapy with aggressive and violent patients. These include ensuring the safety of clinician, patient, and potential victims as the foremost concern; developing a finely detailed assessment of aggressive and violent acts and of the antecedents, assumptions, and consequences that are attached to them; formulating well-defined goals and striving for clear communication to achieve consistency in the pursuit of these goals between therapist and patient, and among therapist and other clinicians, staff, and relevant family members or agencies; specifying ahead of time well-considered outcome measures to be used to gauge the effectiveness of treatment; and maintaining a healthy vigilance for countertransferential and similar reactions and a willingness to use consultation as an integral part of treatment.

The relationship between antisocial and borderline features and aggression in young adult men in treatment for substance use disorders

Shorey, Ryan C.; Elmquist, Joanna; Anderson, Scott; Stuart, Gregory L.

2016-01-01

There is a large literature documenting that adult men in treatment for substance use disorders perpetrate more aggression than men without substance use disorders. Unfortunately, there is minimal research on aggression among young adult men (i.e., 18–25 years of age) in treatment for substance use. Moreover, although aggression is more likely to occur when individuals are acutely intoxicated by alcohol or drugs, research also suggests that antisocial (ASPD) and borderline (BPD) personality features increase the chances an individual will use aggression. The current study therefore examined the associations between ASPD and BPD features, including specific features that are reflective of impulsivity, and aggression in young adult men in treatment for substance use disorders (N = 79). Controlling for age, education, alcohol and drug use, ASPD features were positively associated with various indicators of aggression (e.g., physical, verbal, attitudinal), whereas BPD features were only associated with physical aggression. However, ASPD and BPD features that were specific to impulsivity were robustly related to indicators of aggression. Findings suggest that substance use treatment should attempt to target ASPD and BPD features in young adult men, which may help reduce aggression after treatment. PMID:26941068

Covariation of self- and other-directed aggression among inpatient youth: Continuity in the transition to treatment and shared risk factors

Boxer, Paul

2010-01-01

Although other-directed and self-directed aggression covary in very high risk youth, these forms of aggression infrequently are studied simultaneously. Understanding better their covariation is an important task for improving services to high risk youth. In this study, data from the clinical records of 476 youth admitted to secure inpatient treatment were analyzed to examine relations among self- and other-directed aggression exhibit prior to and during inpatient treatment. Analyses tested the hypotheses that self- and other-directed aggression would tend to covary and display continuity from pre-treatment to in-treatment. Also tested were the hypotheses that youth with histories of co-occurring self- and other-directed aggression would show the highest levels of aggression during treatment and the greatest degree of personal and contextual risk upon entering treatment. These hypotheses were largely supported. Exploratory analyses revealed interesting discontinuities in aggression (aggression emitted only before or during treatment) with critical implications for research and practice with youth receiving clinical care, especially those in institutional placements.

Given the high costs of aggression, why have people evolved to act aggressively? Comparative biologists have frequently observed links between aggression, status, and mating in nonhuman animals. In this series of experiments, the authors examined the effects of status, competition, and mating motives on men's and women's aggression. For men, status motives increased direct aggression (face-to-face confrontation). Men's aggression was also boosted by mating motives, but only when observers were other men. For women, both status and mating motives increased indirect aggression (e.g., socially excluding the perpetrator). Although neither status nor mating motives increased women's direct aggression, women did become more directly aggressive when motivated to compete for scarce resources. These context- and sex-specific effects on human aggression contribute to a broader understanding of the functional nature of aggressive behavior. Copyright (c) 2009 APA, all rights reserved.

Predictors of Aggressive Inflammatory Bowel Disease

Yarur, Andres J.; Strobel, Sebastian G.; Deshpande, Amar R.

2011-01-01

Inflammatory bowel disease comprises a group of conditions characterized by idiopathic inflammation of the gastrointestinal tract. The natural course of disease can range from an indolent course with prolonged periods of remission to aggressive, incapacitating disease. Predicting which patients are more susceptible to developing severe disease is important, especially when choosing therapeutic agents and treatment strategies. This paper reviews current evidence on the main demographic, clinical, endoscopic, histologic, serologic, and genetic markers that predict aggressive inflammatory bowel disease. In ulcerative colitis, we considered disease to be aggressive when patients had a high relapse rate, need for admission and/or surgery, development of colon cancer, or extraintestinal manifestations. We defined aggressive Crohn's disease as having a high relapse rate, development of penetrating disease, need for repeat surgery, or multiple admissions for flares. In Crohn's disease, involvement of the upper gastrointestinal tract and ileum, penetrating disease, early age at diagnosis, smoking, extensive ulceration of the mucosa, high titers of serum antibodies, and mutations of the NOD2 gene are markers of aggressive disease. In ulcerative colitis, patients with more extensive involvement of the colon (pancolitis) have more symptomatology and are at higher risk for needing a colectomy and developing colon cancer. Also, plasmocytic infiltration of the colonic mucosa and crypt atrophy predict treatment failure. As with diagnosis, no single method can predict disease aggressiveness. Multiple serologic and genetic tests are being developed to refine the accuracy of prediction. Endoscopic findings can also predict the future course of disease. At present, clinical manifestations are the most useful way to make therapeutic decisions. PMID:22298958

Abstract Objective: Diagnostic criteria for disruptive mood dysregulation disorder (DMDD) require 1) periodic rageful outbursts and 2) disturbed mood (anger or irritability) that persists most of the time in between outbursts. Stimulant monotherapy, methodically titrated, often culminates in remission of severe aggressive behavior, but it is unclear whether those with persistent mood symptoms benefit less.This study examined the association between the presence of persistent mood disturbances and treatment outcomes among children with attention-deficit/hyperactivity disorder (ADHD) and periodic aggressive, rageful outbursts. Methods: Within a cohort of children with ADHD and aggressive behavior (n = 156), the prevalence of persistent mood symptoms was evaluated at baseline and after completion of a treatment protocol that provided stimulant monotherapy and family-based behavioral treatment (duration mean [SD] = 70.04 [37.83] days). The relationship of persistent mood symptoms on posttreatment aggressive behavior was assessed, as well as changes in mood symptoms. Results: Aggressive behavior and periodic rageful outbursts remitted among 51% of the participants. Persistent mood symptoms at baseline did not affect the odds that aggressive behavior would remit during treatment. Reductions in symptoms of sustained mood disturbance accompanied reductions in periodic outbursts. Children who at baseline had high irritability but low depression ratings showed elevated aggression scores at baseline and after treatment; however, they still displayed large reductions in aggression. Conclusions: Among aggressive children with ADHD, aggressive behaviors are just as likely to decrease following stimulant monotherapy and behavioral treatment among those with sustained mood symptoms and those without. Improvements in mood problems are evident as well. Therefore, the abnormalities in persistent mood described by DMDD's criteria do not contraindicate stimulant therapy as

Second-generation antipsychotics (SGAs) are prescribed for psychosis, aggression, and agitation in Alzheimer disease (AD). To conduct a cost-benefit analysis of SGAs and placebo (taken to represent a "watchful waiting" treatment strategy) for psychosis and aggression in outpatients with AD. Randomized placebo-controlled trial of alternative SGA initiation strategies. Forty-two outpatient clinics. Outpatients with AD and psychosis, aggression, or agitation (N = 421). Intervention Participants were randomly assigned to treatment with olanzapine, quetiapine fumarate, risperidone, or placebo with the option of double-blind rerandomization to another antipsychotic or citalopram hydrobromide or open treatment over 9 months. Monthly interviews documented health service use and costs. The economic perspective addressed total health care and medication costs. Costs of study drugs were estimated from wholesale prices with adjustment for discounts and rebates. Quality-adjusted life-years (QALYs) were assessed with the Health Utilities Index Mark 3 and were supplemented with measures of functioning, activities of daily living, and quality of life. Primary analyses were conducted using all available data. Secondary analyses excluded observations after the first medication change (ie, phase 1 only). Cost-benefit analysis was conducted using the net health benefits approach in a sensitivity analysis in which QALYs were valued at $50,000 per year and $100,000 per year. Average total health costs, including medications, were significantly lower for placebo than for SGAs, by $50 to $100 per month. There were no differences between treatments in QALYs or other measures of function. Phase 1-only analyses were broadly similar. Net-benefit analysis showed greater net health benefits for placebo as compared with other treatments, with probabilities ranging from 50% to 90%. There were no differences in measures of effectiveness between initiation of active treatments or placebo (which

Self-injurious behavior (SIB) and aggression have been the concern of researchers because of the serious impact these behaviors have on individuals' lives. Despite the plethora of research on the treatment of SIB and aggressive behavior, the reported findings have been inconsistent regarding the effectiveness of reinforcement-based versus punishment-based procedures. We conducted a literature review to determine whether a trend could be detected in researchers' selection of reinforcement-based procedures versus punishment-based procedures, particularly since the introduction of functional analysis to behavioral assessment. The data are consistent with predictions made in the past regarding the potential impact of functional analysis methodology. Specifically, the findings indicate that, once maintaining variables for problem behavior are identified, experimenters tend to choose reinforcement-based procedures rather than punishment-based procedures as treatment for both SIB and aggressive behavior. Results indicated an increased interest in studies on the treatment of SIB and aggressive behavior, particularly since 1988. PMID:10396771

Alcohol and cannabis use have been implicated in aggression. Alcohol consumption is known to facilitate aggression, whereas a causal link between cannabis and aggression has not been clearly demonstrated. This study investigated the acute effects of alcohol and cannabis on subjective aggression in alcohol and cannabis users, respectively, following aggression exposure. Drug-free controls served as a reference. It was hypothesized that aggression exposure would increase subjective aggression in alcohol users during alcohol intoxication, whereas it was expected to decrease subjective aggression in cannabis users during cannabis intoxication. Heavy alcohol (n = 20) and regular cannabis users (n = 21), and controls (n = 20) were included in a mixed factorial study. Alcohol and cannabis users received single doses of alcohol and placebo or cannabis and placebo, respectively. Subjective aggression was assessed before and after aggression exposure consisting of administrations of the point-subtraction aggression paradigm (PSAP) and the single category implicit association test (SC-IAT). Testosterone and cortisol levels in response to alcohol/cannabis treatment and aggression exposure were recorded as secondary outcome measures. Subjective aggression significantly increased following aggression exposure in all groups while being sober. Alcohol intoxication increased subjective aggression whereas cannabis decreased the subjective aggression following aggression exposure. Aggressive responses during the PSAP increased following alcohol and decreased following cannabis relative to placebo. Changes in aggressive feeling or response were not correlated to the neuroendocrine response to treatments. It is concluded that alcohol facilitates feelings of aggression whereas cannabis diminishes aggressive feelings in heavy alcohol and regular cannabis users, respectively.

There is a largely unmet need for evidence-based interventions that reduce future aggression and incarceration in clinically aggressive juvenile offenders serving probation. We addressed this gap using a group randomized controlled trial. Offenders both with and without clinical aggression were included, enabling comparison of intervention effects. Juveniles 13 to 17 years old (N = 310, mean = 16 years, 90% African-American, 66% male) on probation were assigned to a 2-week intervention targeting psychosocial factors implicated in risky behavior (e.g., learning strategies to manage "hot" emotions that prompt risk taking) or to an equally intensive health promotion control. Participants completed aggression measures at baseline, 6-, and 12-month follow-up and reported on incarceration at 12 months. Spline regression tested symptom change. Among clinically aggressive offenders (n = 71), the intervention arm showed significantly greater reductions in aggression over the first 6 months compared with controls. Juveniles from the intervention no longer met clinical criteria, on average, but clinically significant symptoms persisted in the control group. By 12 months, participants from the intervention appeared to maintain treatment gains, but their symptom levels no longer differed significantly from those in the control. However, the intervention group was nearly 4 times less likely than controls to report incarceration. Intervention effects were significantly stronger for offenders with clinical than with nonclinical (n = 239) baseline aggression. A 2-week intervention expedited improvements in aggression and reduced incarceration in clinically aggressive juvenile offenders. The findings underscore the importance of directing intervention resources to the most aggressive youth.

Testosterone treatment of men with low testosterone is common and, although relatively short-term, has raised concern regarding an increased risk of prostate cancer (CaP). We investigated the association between modest-duration testosterone treatment and incident aggressive CaP. Retrospective inception cohort study of male Veterans aged 40 to 89 years with a laboratory-defined low testosterone measurement from 2002 to 2011 and recent prostate specific antigen (PSA) testing; excluding those with recent testosterone treatment, prostate or breast cancer, high PSA or prior prostate biopsy. Histologically-confirmed incident aggressive prostate cancer or any prostate cancer were the primary and secondary outcomes, respectively. Of the 147,593 men included, 58,617 were treated with testosterone. 313 aggressive CaPs were diagnosed, 190 among untreated men (incidence rate (IR) 0.57 per 1000 person years, 95% CI 0.49-0.65) and 123 among treated men (IR 0.58 per 1000 person years; 95% CI 0.48-0.69). After adjusting for age, race, hospitalization during year prior to cohort entry, geography, BMI, medical comorbidities, repeated testosterone and PSA testing, testosterone treatment was not associated with incident aggressive CaP (HR 0.89; 95% CI 0.70-1.13) or any CaP (HR 0.90; 95% CI 0.81-1.01). No association between cumulative testosterone dose or formulation and CaP was observed. Among men with low testosterone levels and normal PSA, testosterone treatment was not associated with an increased risk of aggressive or any CaP. The clinical risks and benefits of testosterone treatment can only be fully addressed by large, longer-term randomized controlled trials.

Patients experiencing mental disorders are at an elevated risk for developing aggressive behavior. In the past 10 years, the psychopharmacological treatment of aggression has changed dramatically owing to the introduction of atypical antipsychotics on the market and the increased use of anticonvulsants and lithium in the treatment of aggressive patients.This review (second of 2 parts) uses a translational medicine approach to examine the neurobiology of aggression, discussing the major neurotransmitter systems implicated in its pathogenesis (serotonin, glutamate, norepinephrine, dopamine, and γ-aminobutyric acid) and the neuropharmacological rationale for using atypical antipsychotics, anticonvulsants, and lithium in the therapeutics of aggressive behavior. A critical review of all clinical trials using atypical antipsychotics (aripiprazole, clozapine, loxapine, olanzapine, quetiapine, risperidone, ziprasidone, and amisulpride), anticonvulsants (topiramate, valproate, lamotrigine, and gabapentin), and lithium are presented. Given the complex, multifaceted nature of aggression, a multifunctional combined therapy, targeting different receptors, seems to be the best strategy for treating aggressive behavior. This therapeutic strategy is supported by translational studies and a few human studies, even if additional randomized, double-blind, clinical trials are needed to confirm the clinical efficacy of this framework.

Aggressive Behavior Among Military Veterans in Substance Use Disorder Treatment: The Roles of Posttraumatic Stress and Impulsivity

2015-01-01

This study examined posttraumatic stress disorder (PTSD) symptom severity and impulsivity as predictors of aggressive behavior among 133 male military Veterans entering substance abuse treatment who endorsed difficulty controlling anger in the past year. At treatment intake, participants completed measures assessing PTSD symptom severity, impulsivity and aggressive behavior. Perpetration of aggressive behavior was reassessed four months later. Results from multivariate models indicated that PTSD symptom severity and impulsivity explained unique variance in aggressive behavior at intake but not follow-up. Mediation models indicated that the association between PTSD symptom severity and aggressive behavior was accounted for by impulsivity. The identification of impulsivity as a key mediator between trauma symptoms and aggressive behavior has significant clinical and research implications. Based on these findings, clinicians are encouraged to consider a standard assessment of impulsivity and the selection of interventions that target impulsivity as a trans-diagnostic process among at-risk client populations.

Behavioural and psychological symptoms of dementia (BPSD) include agitation and aggression in people with dementia. BPSD is common on inpatient psychogeriatric units and may prevent individuals from living at home or in residential/nursing home settings. Several drugs and non-pharmacological treatments have been shown to be effective in reducing behavioural and psychological symptoms of dementia. Algorithmic treatment may address the challenge of synthesizing this evidence-based knowledge. A multidisciplinary team created evidence-based algorithms for the treatment of behavioural and psychological symptoms of dementia. We present drug treatment algorithms for agitation and aggression associated with Alzheimer's and mixed Alzheimer's/vascular dementia. Drugs were appraised by psychiatrists based on strength of evidence of efficacy, time to onset of clinical effect, tolerability, ease of use, and efficacy for indications other than behavioural and psychological symptoms of dementia. After baseline assessment and discontinuation of potentially exacerbating medications, sequential trials are recommended with risperidone, aripiprazole or quetiapine, carbamazepine, citalopram, gabapentin, and prazosin. Titration schedules are proposed, with adjustments for frailty. Additional guidance is given on use of electroconvulsive therapy, optimization of existing cholinesterase inhibitors/memantine, and use of pro re nata medications. This algorithm-based approach for drug treatment of agitation/aggression in Alzheimer's/mixed dementia has been implemented in several Canadian Hospital Inpatient Units. Impact should be assessed in future research.

Disentangling functions of online aggression: The Cyber-Aggression Typology Questionnaire (CATQ).

Aggression in online contexts has received much attention over the last decade, yet there is a need for measures identifying the proximal psychological drivers of cyber-aggressive behavior. The purpose of this study was to present data on the newly developed Cyber-Aggression Typology Questionnaire (CATQ) designed to distinguish between four distinct types of cyber-aggression on dimensions of motivational valence and self-control. A sample 314 undergraduate students participated in the study. The results confirmed the predicted four-factor structure providing evidence for distinct and independent impulsive-aversive, controlled-aversive, impulsive-appetitive, and controlled-appetitive cyber-aggression types. Further analyses with the Berlin Cyberbullying Questionnaire, Reactive Proactive Aggression Questionnaire, and the Behavior Inhibition and Activation Systems Scale provide support for convergent and divergent validity. Understanding the motivations facilitating cyber-aggressive behavior could aid researchers in the development of new prevention and intervention strategies that focus on individual differences in maladaptive proximal drivers of aggression.

An aggression policy that works.

PubMed

Kitchener, Denby A; Sykes, Sharon R; McEwan, Allan G

2004-12-13

In 1999, a survey of the clinical staff in Royal Darwin Hospital showed that most instances of aggressive and abusive behaviour by patients or visitors occurring in the hospital went unreported because staff believed there would not be any follow-up investigation or action taken by management, Australia. In response, a hospital working party was formed to develop and implement an aggression management policy with practical effective strategies. The principal tool used was an Action Plan that delineated an immediate response to the aggression, as well as long-term strategies such as negotiated care and behaviour modification programs. An advocate is provided for the patient and debriefing for staff members. If the aggressive behaviour continues, early discharge of the patient could be initiated. The fundamental principle of the policy is to prevent fostering a culture of acceptance of aggressive behaviour through appropriate early intervention. In 2002, a follow-up survey showed that 82% of aggressive incidents were being reported and dealt with by management in a timely manner -- a significant improvement.

Staff-reported antecedents to aggression in a post-acute brain injury treatment programme: what are they and what implications do they have for treatment?

2013-01-01

Research in psychiatric settings has found that staff attribute the majority of in-patient aggression to immediate environmental stressors. We sought to determine if staff working with persons with brain injury-related severe and chronic impairment make similar causal attributions. If immediate environmental stressors precipitate the majority of aggressive incidents in this client group, it is possible an increased focus on the management of factors that initiate client aggression may be helpful. The research was conducted in a low-demand treatment programme for individuals with chronic cognitive impairment due to acquired brain injury. Over a six-week period, 63 staff and a research assistant reported on 508 aggressive incidents. Staff views as to the causes of client aggression were elicited within 72 hours of observing an aggressive incident. Staff descriptions of causes were categorised using qualitative methods and analysed both qualitatively and quantitatively. Aggression towards staff was predominantly preceded by (a) actions that interrupted or redirected a client behaviour, (b) an activity demand, or (c) a physical intrusion. The majority of aggressive incidents appeared hostile/angry in nature and were not considered by staff to be pre-meditated. Common treatment approaches can be usefully augmented by a renewed focus on interventions aimed at reducing antecedents that provoke aggression. Possible approaches for achieving this are considered.

[Motives and interpersonal functions of aggression].

PubMed

Ohbuchi, K

1987-06-01

In this review, the author theoretically and empirically examined motives and interpersonal functions of aggression. A factor-analysis of Averill's questionnaire items on anger revealed that motives involved in aggressive responses were clustered into two groups: the hostile and the instrumental. It was also clarified that an individual is likely to engage in aggression particularly when some hostile motives are evoked. Concerning the interpersonal functions, the author proposed that aggression might serve four principal goals. (1) Aggression can be generated as an avoidance response to an aversive stimulus, such as frustration, annoyance, or pain, and so on. It depends on the severity of the stimulus. It was however emphasized that aggression is also mediated by social cognition, such as an attribution of intent to a harm-doer. (2) Aggression can be used as a means of coercing the other person into doing something. An individual is likely to use such a power strategy if he/she is lacking in self-confidence or a perspective for influencing the target person by more peaceful strategies. (3) Aggression can be interpreted as a punishment when it is directed toward a transgressor. In this case, aggression is motivated by restoration of a social justice, and thus its intensity is determined by the perceived moral responsibility of the transgressor. Further, it was indicated that aggression is intensified if it is justified as a sanctional conduct against the immoral. (4) Aggression can be also evoked when an individual's social identity is threatened. It was suggested that impression management motives are involved in aggression by an unexpected finding that the presence of audience or the identifiability rather facilitated retaliative aggression. The aggression-inhibition effect of apology was also explained in terms of impression management. In conclusion, it was presented that aggression is a behavioral strategy as an attempt to resolve interpersonal conflicts

Aggressive periodontitis (AP) is a condition that promotes breakdown of the periodontal tissues in a short time. In severe cases, pathologic migration of teeth and tooth loss can occur, producing esthetic and functional problems for the patient. Orthodontic treatment may be recommended to restore esthetics and masticatory function. We assessed the effects of orthodontic movement in the periodontal tissues of treated patients with AP. Ten subjects (ages 25.0 ± 5.22 years) with AP received periodontal treatment followed by orthodontic treatment. Maintenance sessions were performed monthly under a strict dental biofilm control. They were compared with 10 periodontally healthy subjects (ages 22.9 ± 5.23 years) who received orthodontic treatment. Probing pocket depth, clinical attachment level, bleeding on probing, and dental plaque index were measured at baseline, after orthodontic treatment, and after 4 months. Statistical analysis showed improvement in all clinical parameters between baseline and 4 months after orthodontic treatment: probing pocket depth (0.29 mm), clinical attachment level (0.38 mm), bleeding on probing (4.0%), and dental plaque index (11%). The periodontal parameters of the AP patients remained stable during orthodontic treatment under strict biofilm control. Copyright © 2018 American Association of Orthodontists.

In the current study, the associations between inpatient aggression and the living group climate as perceived by the adolescents admitted to a forensic psychiatric treatment unit, are investigated based on carefully registered longitudinal data. Multilevel regression analyses revealed a significant inverse relation between the number and severity of aggressive incidents and the amount of support, as well as with the possibilities of growth perceived by the adolescents. No significant associations of aggression and the perception of repression or atmosphere are found. Our study reveals preliminary evidence for the relation between the prevalence of aggressive incidents and how the adolescents perceive social contextual factors in daily forensic treatment practices. Moreover, preliminary evidence that evidence-based treatment programs and psychiatric care have an important influence on experienced possibilities for growth and support and as such prevent institutional aggression, is found.

Aggressive challenging behaviour and intellectual disability.

Benson, Betsey A; Brooks, Whitney T

2008-09-01

The aim of this article is to review reports of aggressive challenging behaviour in individuals with intellectual disability from September 2006 to March 2008. Studies continued to demonstrate the prevalence and significance of aggressive challenging behaviour in persons with intellectual disability. Over half of the population engages in some form of aggression, but only a small number is responsible for frequent or severe acts. A publication that identified aggression profiles offered a promising new approach. Aggressive behaviour in adults often has multiple functions. The most frequently studied interventions were either behavioural or somatic. Parents learned skills to effectively intervene with their aggressive preschool child. Reviews of medication efficacy studies concluded that there was insufficient evidence to recommend a single medication. Psychiatrists agreed that medication should not be the first treatment option. In one study, a class of medication was found to reduce aggression, but not aggression with self-injury, or self-injury alone. Research on aggressive challenging behaviour requires assessment instruments that address the topography and severity of aggression. Identifying aggression types may clarify mixed results of previous research and improve treatment effectiveness. Greater access to effective, nonmedication treatments is needed.

Studies of violence in substance use disorder (SUD) treatment settings typically focus on partner aggression (PA) although non-partner aggression (NPA) is also a common problem. This study examines potentially distinct paths of distal and proximal risk factors related to aggression towards non-partners (NPA) and partners (PA) among a SUD treatment sample. The sample included 176 adults reporting past-year violence. Bivariate analyses indicated several distal and proximal factors were associated with NPA and PA. According to multivariate, multiple mediation analyses youth aggression history was a factor for both NPA and PA. Alcohol and cocaine use and psychological distress were associated with NPA; marijuana use was associated with PA. There also was evidence of indirect effects of distal factors on NPA and PA. The results suggest that there may be substantially different dynamics associated with NPA and PA, and have implications for developing screening, assessment and treatment protocols targeting violence among individuals in SUD treatment.

To describe outcomes in a cohort of extremely premature infants treated for aggressive posterior retinopathy of prematurity by diode laser panretinal photocoagulation. Retrospective study. Fifteen eyes in eight infants. A review was carried out on infants between 23 and 25.6 weeks gestational age admitted to The Royal Brisbane and Women's Hospital neonatal intensive care unit between 1992 and 2009. Success of treatment, visual and refractive outcomes. Five hundred fifty-four infants were admitted to neonatal intensive care unit, 373 survived till screening, and 304 had retinopathy of prematurity. Sixty-six infants required treatment, and eight of these had aggressive posterior retinopathy of prematurity (2.5% of all infants with retinopathy of prematurity). Mean gestational age was 24.2 weeks, mean birthweight was 634 g, and treatment occurred at mean 34.1 weeks post-menstrual age. The mean total number of burns per eye was 2967. Five of 15 treated eyes required retreatment. Two patients subsequently died of unrelated causes. Regression occurred in 9 of 11 remaining eyes; one eye progressed to stage 4b and another to stage 5 retinopathy of prematurity. Vitrectomy was performed in two eyes. Five eyes had 6/12 vision, one had 3/60, and three had no perception of light. Of the remaining two eyes, one had good fixation and the other had poor fixation. Despite good structural outcomes, visual outcomes for conventional laser treatment of aggressive posterior retinopathy of prematurity are poor. © 2013 Royal Australian and New Zealand College of Ophthalmologists.

Neuroimaging and Neurocognitive Correlates of Aggression and Violence in Schizophrenia

Weiss, Elisabeth M.

2012-01-01

Individuals diagnosed with major mental disorders such as schizophrenia are more likely to have engaged in violent behavior than mentally healthy members of the same communities. Although aggressive acts can have numerous causes, research about the underlying neurobiology of violence and aggression in schizophrenia can lead to a better understanding of the heterogeneous nature of that behavior and can assist in developing new treatment strategies. The purpose of this paper is to review the recent literature and discuss some of the neurobiological correlates of aggression and violence. The focus will be on schizophrenia, and the results of neuroimaging and neuropsychological studies that have directly investigated brain functioning and/or structure in aggressive and violent samples will be discussed as well as other domains that might predispose to aggression and violence such as deficits in responding to the emotional expressions of others, impulsivity, and psychopathological symptoms. Finally gender differences regarding aggression and violence are discussed. In this context several methodological and conceptional issues that limited the comparison of these studies will be addressed. PMID:24278673

Generalized aggressive periodontitis (GAgP) is a distinct type of periodontal disease associated with considerably more rapid periodontal tissue destruction than chronic periodontitis. This study presents the 5-year follow-up of a patient with GAgP. A 29-year-old man reported experiencing increasing gingival recession. He was treated using cause-related therapy, provisional splints, and flap surgery combined with allograft grafting and was followed up for 5 years. This case study shows that elimination of infectious microorganisms and meticulous long-term maintenance provide an effective treatment modality for aggressive periodontitis cases. This treatment modality can restore the masticatory function and provide the GAgP patient with improved quality of life.

A less aggressive treatment strategy is proposed in the area of children's voice disorders. Speech clinicians are urged not to be over-zealous in imposition of their own voice standards. The potential threat that vocal pathologies hold for children's larynges is felt to be largely over-rated. (Author/JDD)

Previous "Treatment of Severe Childhood Aggression" (TOSCA) reports demonstrated that many children with severe physical aggression and attention-deficit/hyperactivity disorder (ADHD) responded well to two randomized treatments (parent training [PT]+stimulant+placebo = Basic vs. PT+stimulant+risperidone = Augmented) for 9 weeks. An important clinical question is whether these favorable outcomes are maintained over longer times. Clinical responders to the 9-week trial (n = 103/168), defined as Clinical Global Impressions (CGI)-Improvement of much/very much improved plus substantial reduction in parent ratings of disruptiveness, were followed another 12 weeks (21 weeks total) while remaining on blinded treatment. Outcome measures included Clinical Global Impressions scale, Nisonger Child Behavior Rating Form (NCBRF), other parent/teacher-rated scales, laboratory tests, clinician ratings of abnormal movement, and other adverse events (AEs). Parent ratings of problem behavior showed minimal worsening of behavior from end of the 9-week acute trial (expected from regression to the mean after selecting best responders), but outcomes at Extension endpoint were meaningfully improved compared with acute study baseline. As expected, outcomes for Basic and Augmented treatment did not differ among these children selected for good clinical response. During Extension, more Augmented subjects had elevated prolactin; there were no clinically confirmed cases of tardive dyskinesia. Delayed sleep onset was the most frequent Basic AE. We also conducted a last-observation-carried-forward analysis, which included both nonresponders and responders. We found that, at the end of Extension, Augmented subjects had more improvement than Basic subjects on the NCBRF Positive Social subscale (p = 0.005; d = 0.44), the Antisocial Behavior Scale Reactive Aggression subscale (p = 0.03; d = 0.36), and marginally so on the Disruptive Behavior Total subscale (p = 0

The primary objectives of this investigation were to examine the attributions, emotional reactions, and coping strategies of shy/withdrawn and aggressive girls and boys and to examine whether such social cognitions differ within the relationship context of friendship. Drawn from a sample of 5th and 6th graders (M age = 10.79 years; SD = .77), 78 shy/withdrawn, 76 aggressive, and 85 control children were presented with hypothetical social situations that first involved unfamiliar peers, then a mutual good friend. Results revealed group and gender differences and similarities, depending on the relationship context. From our findings emerges a central message: friends' involvement during interpersonal challenges or stressors mitigates children's attributions, emotions and coping responses. PMID:16611178

2017-10-01

This study examined the relationships among attitude toward violence, self-esteem, emotion dysregulation, anger, and aggression in community men and women and male inmates. Overall, 166 community men, 197 community women, and 100 male inmates completed a battery of questionnaires containing self-reported measures. Self-esteem and attitude toward violence were significant predictors of aggressive behavior, with emotion dysregulation mediating the relationship between self-esteem and the criterion variable. Anger mediated the relationship between emotion dysregulation and aggressive behavior only among community people. Among men, inmates reported a more favorable attitude toward violence, lower self-esteem, higher emotion dysregulation, more aggressive behaviors, and a lower tendency to get angry. Women showed a less favorable attitude toward violence, lower self-esteem, higher emotion dysregulation, and a higher tendency for anger than men, while no differences emerged for aggressive behavior. These findings suggest that self-related constructs and emotion regulation strategies represent key processes associated with aggressive behavior among all participants, while the role of anger is more prominent in community people. To reduce aggressive tendencies, treatment and prevention interventions might increase self-esteem, emotion regulation skills, and one's ability to direct anger toward other goals. Moreover, programs aimed at changing attitudes toward violence could be useful.

Prevalence and risk factors of inpatient aggression by adults with intellectual disabilities and severe challenging behaviour: a long-term prospective study in two Dutch treatment facilities.

PubMed

Drieschner, Klaus H; Marrozos, Isabel; Regenboog, Maarten

2013-08-01

Over five years, various types of aggressive incidents by 421 intellectually disabled inpatients were recorded on a daily basis, using an adapted version of the Modified Overt Aggression Scale. Stable patient characteristics (e.g., gender, intelligence, DSM IV classification at the start of treatment) and pre-treatment scores of two treatment outcome measures (e.g., Adult Behavior Checklist and Dynamic Risk Outcome Scale) were used to predict aggression during the treatment. At an overall average of one incident per patient per week, about ten times more aggression occurred on admission compared to resocialisation wards, and the 20% most aggressive individuals caused 50% of the verbal and 80% of the physical incidents. The best predictor of aggressive behaviour was aggression early in treatment, followed by coping skills deficits and impulsiveness. The relevance of the results for the treatment of aggressive behaviour and methodological issues in the recording of inpatient aggression are discussed. Copyright © 2013 Elsevier Ltd.

2008-09-01

Feline aggression-between cats or directed at humans-is, after inappropriate elimination and urine-marking behaviors, the second most common reason cats are seen by behavioral specialists. For diagnosis and treatment it is important to determine the motivation for the aggression. The more common causes for human-directed aggression in cats include play, fear, petting intolerance, and redirected aggression. Other causes include pain and maternal behavior. Sexually motivated and status related aggression are much more rare. Treatment includes a combination of behavioral modification, environmental modification, and, in some cases, medication.

Aggression and violence around the world: A model of CLimate, Aggression, and Self-control in Humans (CLASH).

PubMed

Van Lange, Paul A M; Rinderu, Maria I; Bushman, Brad J

2017-01-01

Worldwide there are substantial differences within and between countries in aggression and violence. Although there are various exceptions, a general rule is that aggression and violence increase as one moves closer to the equator, which suggests the important role of climate differences. While this pattern is robust, theoretical explanations for these large differences in aggression and violence within countries and around the world are lacking. Most extant explanations focus on the influence of average temperature as a factor that triggers aggression (The General Aggression Model), or the notion that warm temperature allows for more social interaction situations (Routine Activity Theory) in which aggression is likely to unfold. We propose a new model, CLimate, Aggression, and Self-control in Humans (CLASH), that helps us to understand differences within and between countries in aggression and violence in terms of differences in climate. Lower temperatures, and especially larger degrees of seasonal variation in climate, call for individuals and groups to adopt a slower life history strategy, a greater focus on the future (vs. present), and a stronger focus on self-control. The CLASH model further outlines that slow life strategy, future orientation, and strong self-control are important determinants of inhibiting aggression and violence. We also discuss how CLASH differs from other recently developed models that emphasize climate differences for understanding conflict. We conclude by discussing the theoretical and societal importance of climate in shaping individual and societal differences in aggression and violence.

Sector of Social Behavior Neurogenetics, Institute of Cytology and Genetics, Siberian Branch, Effects of sodium valproate on the aggressive behavior of male mice with 2- and 20-day positive fighting experience have been studied. It is established that valproate administered in a singe dose of 100 mg/kg has no effect on the behavior of male mice with a 2-day experience of aggression. The treatment of mice with 300 mg/kg of valproate significantly decreased the level of aggressive motivation and the percentage of animals demonstrating attacks and threats. In male mice with a 20-day experience of aggression, valproate decreased the time of hostile behavior in a dose-dependent manner. Valproate in a single dose of 300 mg/kg significantly decreased the level of aggressive motivation, but also produced a toxic effect, whereby 73% of aggressive males demonstrated long-term immobility and 45% exhibited movement abnormalities (falls) upon the treatment. It is suggested that changes in the brain neurochemical activity, which are caused by a prolonged experience of aggression, modify the effects of sodium valproate.

Vasospasm is a major cause of morbidity and mortality in patients after aneurysmal subarachnoid hemorrhage. Early treatment of ruptured aneurysms is advocated; delayed intervention complicates the treatment strategy leading to significant vasospasm and poor prognosis. We report an endovascular protocol for occlusion of the unsecured aneurysm and angioplasty for vasospasm in a single session. Between January 2011 and May 2017, among 660 patients with aneurysmal subarachnoid hemorrhage, 24 patients with significant vasospasm and unsecured ruptured cerebral aneurysm were reviewed. Continuous nimodipine drip through a pressure line of the guiding catheter was set up. Aggressive angioplasty with a compliant balloon catheter either before or after embolization of the aneurysm in the major branches of vasospastic territory was performed. The goal was complete embolization of the aneurysm. Of 24 patients, 17 had ischemic symptoms at presentation, and the average delay from aneurysm rupture to presentation was 7.58 days. Angioplasty and nimodipine drip were performed on all patients. Severity of vasospasm was significantly reduced, and outcome improved in each patient. Two patients required a second angioplasty. In 20 patients, embolization of aneurysms was achieved without any aneurysmal sac or residual neck. Clinical outcome was good recovery (modified Rankin Scale score 0-2) in 23 patients (95.8%) and moderate disability in 1 patient (modified Rankin Scale score 3). Aggressive endovascular treatment of patients with unsecured ruptured cerebral aneurysm and associated vasospasm is safe and effective. Copyright © 2018 Elsevier Inc. All rights reserved.

2012-01-01

Purpose: This research evaluated an individualized Internet training designed to teach nurse aides (NAs) strategies to prevent or, if necessary, react to resident aggression in ways that are safe for the resident as well as the caregiver. Design and Methods: A randomized treatment and control design was implemented, with baseline, 1-, and 2-month assessments for 158 NAs. The training involved 2 weekly visits. The Internet intervention was a behaviorally focused and video-based training that included content on skills for safely dealing with physical aggression. Measures included video situation testing and assessment of psychosocial constructs associated with behavior change. Results: Analysis of covariance showed positive results for knowledge, attitudes, self-efficacy, and empathy, with medium–large effect sizes maintained after 2 months. The training was well received by participants. Implications: Internet training is a viable approach to shape appropriate NA reactions to aggressive resident behaviors. This format has future potential because it offers fidelity of presentation and automated documentation, with minimal supervision. PMID:22038338

Proven practices for reducing aggressive and noncompliant behaviors exhibited by young children at home and at school.

PubMed

Vanderheyden, A; Witt, J C

2000-10-01

One of the single most powerful predictors of aggressive and noncompliant behaviors exhibited in early childhood is coercive parent-child interaction. Coercive parent-child interaction has been linked to multiple negative outcomes in the lives of children. When children learn to relate to their parents and the world in the context of coercive interaction, they are likely to experience significant deficits in the prosocial skills critical to school success. These children are much more likely to experience school failure and teacher and peer rejection. Further, when noncompliant and aggressive children enter school, they are most frequently exposed to a series of ineffective and increasingly restrictive treatments. Proven strategies exist to teach parents and children prosocial ways of interacting and to address these problems in the classroom, but in many cases these types of services are not easily accessible or routinely available. This paper makes recommendations for identifying effective, proven treatment strategies when practitioners observe coercive parent-child interaction or child noncompliance and aggression.

Aggressive behaviour in adolescent psychiatric settings: what are risk factors, possible interventions and implications for nursing practice? A literature review.

2009-09-01

This study was aimed to identify the risk factors of aggressive behaviour in adolescents (1318 years), and to describe available intervention strategies. The findings are evaluated on the basis of their implications for nursing practice. Aggressive behaviour in adolescent psychiatric settings is a neglected research area. The consequences of aggressive behaviour on nurses, other patients and the therapeutic environment can be profound. For the development and implementation of innovative intervention strategies aimed at preventing aggressive behaviour in adolescent psychiatric patients, knowledge of risk factors and evidence-based interventions for aggressive behaviour are of the utmost importance. A systematic search of PubMed, Cinahl, PsychINFO and Cochrane Systematic Reviews (19912007) was employed. The risk factors for aggressive behaviour comprise personal and environmental risk factors. Some risk factors can be influenced by nursing intervention strategies. Available intervention programmes range from interpersonal skills training to massage therapy, parent management training, functional family therapy and multi-systemic therapy. The most effective programmes combine interpersonal skills training with parent management training. No specific nursing intervention programmes were found for dealing with aggressive behaviour in adolescent patients. Nursing staff can assist in achieving a systematic improvement in the treatment outcomes of existing intervention programmes for the prevention of aggression. There is a need for specific nursing intervention programmes to deal with aggressive behaviour in adolescent psychiatric settings.

In the Barcelona Clinic Liver Cancer (BCLC) system, only sorafenib is suggested for HCC patients having performance status (PS) 1 or 2 even if they have treatable lesions. In the current study, we aimed to explore the outcome of using aggressive treatment for HCC patients with PS 1 and 2. Five hundred and twenty four patients with HCC were enrolled in this study and divided into 2 groups: 404 PS 1 and 120 PS 2. Of the included 524 patients, 136 recceived non-aggressive supportive treatment and sorafenib, while 388 patients were offered aggressive treatment in the form of surgical resection, transplantation, percutaneous ablation, trans-arterial chemoembolization and/or chemoperfusion. All the patients were followed up for a period of 2 years to determine their survival. Most HCC patients were CHILD A and B grades (89.4% versus 85.0%, for PS1 and PS2, respectively). Patients with PS1 were significantly younger. Out of the enrolled 524 patients, 388 were offered aggressive treatment, 253 (65.2%) having their lesions fully ablated, 94 (24.2%) undergoing partial ablation and 41 patients with no ablation (10.6%). The median survival of the patients with PS 1 who were offered aggressive treatment was 20 months versus 9 months only for those who were offered supportive treatment and sorafenib (<0.001). Regarding HCC patients with PS 2, the median survivals were similarly 19.7 months versus 8.7 months only (<0.001). Aggressive treatment of HCC patients with PS 1 and 2 significantly improves their survival. Revising the BCLC guidelines regarding such patients is recommended.

Aggressive vertebral hemangiomas are rare tumors of the spine. The treatment management strategy usually consists of vertebroplasty, radiation therapy or in rare cases of surgical strategy. We present a case of a bulging sacral S1-S2 hemangioma in the spinal canal that could not be managed in the usual manner. Here, we demonstrate the usefulness of radiofrequency ablation technique as an alternative treatment as well as robotic assistance for optimal placement of the ablation probe within the lesion.

This study extends the use of the Impulsive/Premeditated Aggression Scale for subtyping aggressive behavior among adolescents with Conduct Disorder. Of the Conduct Disorder symptoms, aggression has the strongest prognostic and treatment implications. While aggression is a complex construct, convergent evidence supports a dichotomy of impulsive and premeditated aggressive subtypes that are qualitatively different from one another in terms of phenomenology and neurobiology. Previous attempts at measuring subtypes of aggression in children and adults are not clearly generalizable to adolescents. Sixty-six adolescents completed a questionnaire for characterizing aggression (Impulsive/Premeditated Aggression Scale), along with standard measures of personality and general functioning. Principal components analysis demonstrated two stable factors of aggression with good internal consistency and construct validity. Compared to the premeditated aggression factor, the impulsive aggression factor was associated with a broader range of personality, thought, emotional, and social problems. As in the adult and child literature, characterization of aggressive behavior into two subtypes appears to be relevant to understanding individual differences among adolescents with Conduct Disorder.

2010-04-01

Research examining the role of pharmacological therapy in the treatment of children and adolescents with clinical disorders is growing. Clinical disorders that present with comorbid aggression can add a challenge to treatment. Child and adolescent neuropsychiatric disorders associated with aggression include attention-deficit hyperactivity disorder, various mood disorders and in particular bipolar disorders/pediatric mania, schizophrenia, mental retardation, oppositional defiant disorder, conduct disorder, and autism spectrum disorders. This review describes the psychopharmacy to treat these disorders and the aggression that often appears comorbidly. Existing literature regarding the efficacy and safety of psychotropics for youth with neuropsychiatric disorders also is discussed. In addition, general guidelines for psychopharmacy of aggression in children and adolescents are presented. Studies reviewed in this article provide evidence for the use of psychostimulants, alpha-2 agonists, beta blockers, lithium, anticonvulsant mood-stabilizers, atypical antipsychotics, traditional antipsychotics, and selective serotonin reuptake inhibitors in treating pediatric aggression with the choice of medication dependent on symptomology. Despite increased support for pediatric psychotropic use, there is a need for more long-term safety and efficacy studies of existing medications and newer, safer, and more effective agents with fewer side effects for the pharmacological treatment of all childhood disorders in which aggression is prominent. 2010 APA, all rights reserved

Background: The success of combined periodontal and orthodontic approach in the treatment of aggressive periodontitis patients with the pathologic extruded anterior teeth is a main concern and stability of the treatment results is an important factor to evaluate the treatment. The present study investigated the periodontal parameters at the end of the orthodontic treatment in patients with the aggressive periodontitis. Materials and Methods: Eight patients with an aggressive periodontal disease, extruded maxillary incisors, infrabony defects and probing depth of ≥5 mm were enrolled in this clinical trial (before, after). After periodontal therapy, orthodontic treatment was carried out for intrusion and alignment of teeth. Plaque index (PI), probing pocket depth (PPD), distance between incisal edge and interdental papilla, root length (RL), and defect dimensions (depth and width) were examined at the end of treatment and three as well as 6 months afterward. The data were subjected to repeated measure ANOVA test. P < 0.05 was considered as significant. Results: There was statistically significant decrease in PPD, PI, and depth of the defects during T0, T3 and T6 (P < 0.05). No significant differences were observed in the RL and distance between incisal edge and interdental papilla (P = 0.95). Furthermore, width of the defects demonstrated significant decrease up to T3 (P = 0.042) while no significant changes from 3 months to 6 months were noted (P = 0.59). Conclusion: The results showed that combined periodontal and orthodontic approach would be a successful treatment with acceptable stability in the case of regular follow-up visits and controlled oral hygiene habits.

Naked aggression: Personality and portfolio manager performance

PubMed Central

2018-01-01

We provide evidence that a personality trait, aggression, has a first-order effect on group financial decision making. In a laboratory experiment on group portfolio choice, highly aggressive subjects (measured by a standard psychology test) were much more likely to recommend risky investment strategies consistent with their own personal information, regardless of the information received by other group members. Outside of this group context, aggression had no effect on subject behavior. Thus, our aggression measure appears to capture an aggressive disposition, which seeks to dominate group decisions, rather than simply reflect risk attitudes or cognitive biases. PMID:29432449

2016-02-01

Aggressive behavior by patients with severe mental illness is a major problem needing intervention. This descriptive cross sectional study examined the perception and coping strategies of caregivers with a sample of 100 toward aggressive behavior by patients with severe mental illness in the outpatient and inpatient unit of the department of psychiatry in a tertiary care hospital. The data were collected by a semistructured interview using Revised Overt Aggression Scale-modified, Aggressive Behavior and Intervention Checklist, Ways of Coping Checklist-Hindi Adaptation and Impact of Patient Aggression on Carers Scale-Adapted. The caregivers perceived aggression in varying extent from the patients. Majority used problem-focused coping to deal with aggressive behavior. Most of the caregivers perceived insisting to take medicines and talking about patient's illness as the triggers for aggressive behavior which was managed by talking to the patient calmly, lovingly and by leaving the patient alone. The findings strongly suggest aggressive behavior as a frequent problem faced by family members of patient with severe mental illness. Nursing interventions should focus on counseling and psycho education for empowering caregivers to utilize strategies to reduce occurrence of aggressive behavior from patient and ways to effectively cope with the situation.

1993-12-01

A sample of 52 Black aggressive, rejected and nonaggressive, rejected children were randomly assigned to receive a social relations intervention or to be in a nonintervention control group. The school-based intervention for fourth-grade children focused on positive social skill training and cognitive-behavioral strategies to promote deliberate, nonimpulsive problem solving. At both the post-treatment and the 1-year follow-up assessments, the social relations intervention was found to be effective only with the aggressive, rejected children. Implications for the importance of assessing subtypes of rejected children are discussed.

Development of a diabetes treatment simulation model: with application to assessing alternative treatment intensification strategies on survival and diabetes-related complications.

The objective of this analysis is to project the long-term impacts on life expectancy and occurrence over 5, 10, and 40 years of microvascular and macrovascular complications of diabetes when using different haemoglobin A1c (HbA1c) thresholds for intensifying treatment of type 2 diabetes. A flexible, discrete-event simulation model has been developed to evaluate alternative treatment strategies based on the United Kingdom Prospective Diabetes Study Outcomes Model. In the present analysis, the model is used to investigate the impact of alternative HbA1c thresholds for treatment intensification ranging from 7.0 to 9.0%. For each intensification strategy, the model is run using 80 simulated patients for each of 1224 patient profiles from the Real-Life Effectiveness and Care Patterns of Diabetes Management study (for a total of 97,920 simulated patients) to project the number of patients who will experience diabetes-related complications over time. The use of lower HbA1c thresholds for intensifying treatment is associated with improved long-term outcomes. When the HbA1c threshold for intensifying therapy from oral treatment to basal insulin (T1) is 7.0% and the threshold for intensifying basal insulin to multiple-dose insulin (T2) is 7.0%, simulated patients spend 54% of their time with HbA1c >7.0%, but 95% of their time with HbA1c >7.0% if T1 and T2 are set to 9.0%. More aggressive or proactive treatment postures are projected to reduce clinical events, including diabetes-related deaths and diabetes-related complications, particularly myocardial infarctions (MIs). When T1 and T2 are set to 7.0%, there are 592 fewer diabetes-related deaths in the first 5 years of the simulation and 3740 fewer deaths over 40 years compared with the results when T1 and T2 are set to 9.0%. These decreases in deaths were also associated with a 0.35 year gain in projected life expectancy. Compared with an aggressive strategy with both T1 and T2 being 7%, 644 more patients are projected to

Aggression from psychiatric patients is a constant problem for care providers that causes major problems in the therapeutic environment, and may have negative effects on the quality of care. Since recognition of aggression with regard to cultural background leads to better control of aggression in the psychiatric wards, this study has been done to clarify Iranian nurses' experiences of aggression in psychiatric wards. A qualitative content analysis study was conducted to explore experiences of nurses. Data analysis revealed four themes: (1) Damage resulting from aggression, (2) Aggression catalysts, (3) Contagious nature of aggression, and (4) Various control strategies. There are various causes for in-patients' aggression, and nurses use various approaches to control it. These approaches are influenced by personnel, facilities, and ward environment. Identifying these factors and strategies can contribute to better management of aggression and, thus, better quality of care in psychiatric wards.

Three levels of thalamic stimulation (low, medium, and high) were combined with the perifornix stimulations. High level thalamic stimulation tended to facilitate the aggressive response elicited by low level perifornix stimulation. Thalamic lesions attenuated the aggression response, especially those elicited during high level perifornix stimulation. It was suggested that within the hypothalamic induced aggression circuitry the center median nucleus modulates the excitatory state of the system. The discussion concerns anatomic and physiologic pathways through which the center median nucleus may modulate the sensory, motor, and affective-autonomic subsystems into a well integrated aggressive state. These experimental findings are supported by the clinically established treatment of aggression by stereotaxic lesions placed in the center median nucleus.

Ceramide (Cer) and sphingosine (Sph) interfere with critical cellular functions relevant for cancer progression and cell survival. While Cer has already been investigated as a potential drug target for lymphoma treatment, information about the potency of sphingosine is scarce. The aim of this study therefore was to evaluate Sph and its synthetic stereoisomer L-threo-sphingosine (Lt-Sph) as potential treatment options for aggressive lymphomas. Diffuse large B cell lymphoma (DLBCL) cell lines were incubated with Sph and Lt-Sph and consequently analysed by flow cytometry (FACS), enzyme-linked immunosorbent assay (ELISA), liquid chromatography coupled to triple-quadrupole mass spectrometry (LC/MS/MS), electron microscopy, and Western blot. Sph induced cell death and blocked cell growth independently of S1P receptors in different DLBCL cell lines. Three different modes of Sph-mediated cell death were observed: Apoptosis, autophagy, and protein kinase C (PKC) inhibition. Generation of pro-apoptotic Cer accounted only for a minor portion of the apoptotic rate. Sph and its analogues could evolve as alternative treatment options for aggressive lymphomas via PKC inhibition, apoptosis, and autophagy. These physiological responses induced by different intracellular signalling cascades (phosphorylation of JNK, PARP cleavage, LC3-II accumulation) identify Sph and analogues as potent cell death inducing agents. © 2014 S.

2014-01-01

Sebaceous carcinoma (SC) is an uncommon neoplasm manifesting itself either in the eyelid or extraocularly in the head and neck area. Surgery is the standard of care. Irradiation is rarely proposed as monotherapy but is frequently administered as an adjuvant regimen following surgical resection. There is no known strategy concerning chemotherapeutic treatment in highly aggressive recurrent – or metastatic – forms of the disease. Our patient presented with an aggressive SC of the scalp recurring after multiple excisions and local radiotherapy. Chemotherapy with 5-fluorouracil, cisplatin and docetaxel was then initiated; 4 cycles were administered, followed by capecitabine maintenance. Shortly after starting chemotherapy, dermal lesions had completely disappeared and radiological response could be seen. The patient experienced an extended period (>20 months) of complete remission. In this report, we show an excellent response of a highly aggressive SC after a combination of chemotherapy as for head and neck cancers. PMID:24748864

Escalated or abnormal aggression induced by early adverse experiences is a growing issue of social concern and urges the development of effective treatment strategies. Here we report that synergistic interactions between psychosocial and biological factors specifically ameliorate escalated aggression induced by early adverse experiences. Rats reared in isolation from weaning until early adulthood showed abnormal forms of aggression and social deficits that were temporarily ameliorated by re-socialization, but aggression again escalated in a novel environment. We demonstrate that when re-socialization was combined with the antidepressant fluoxetine, which has been shown to reactivate juvenile-like state of plasticity, escalated aggression was greatly attenuated, while neither treatment alone was effective. Early isolation induced a permanent, re-socialization resistant reduction in Bdnf expression in the amygdala and the infralimbic cortex. Only the combined treatment of fluoxetine and re-socialization was able to recover Bdnf expression via epigenetic regulation. Moreover, the behavior improvement after the combined treatment was dependent on TrkB activity. Combined treatment specifically strengthened the input from the ventral hippocampus to the mPFC suggesting that this pathway is an important mediator of the beneficial behavioral effects of the combined psychosocial and pharmacological treatment of abnormal aggression. Our findings suggest that synergy between pharmacological induction of plasticity and psychosocial rehabilitation could enhance the efficacy of therapies for pathological aggression. PMID:28685757

Environmental and nursing-staff factors contributing to aggressive and violent behaviour of patients in mental health facilities.

Aggressive and violent behaviour of inpatients in mental health facilities disrupts the therapeutic alliance and hampers treatment. The aim of the study was to describe patients' perceptions of the possible environmental and staff factors that might contribute to their aggressive and violent behaviour after admission to a mental health facility; and to propose strategies to prevent and manage such behaviour. A qualitative, phenomenological study was utilised, in which purposefully sampled inpatients were interviewed over a six-month period. Inpatients were invited to participate if they had been admitted for at least seven days and were in touch with reality. Forty inpatients in two mental health facilities in Cape Town participated in face-to-face, semi-structured interviews over a period of six months. Tesch's descriptive method of open coding formed the framework for the data analysis and presentation of the results. Trustworthiness was ensured in accordance with the principles of credibility, confirmability, transferability and dependability. Analysis of the data indicates two central categories in the factors contributing to patients' aggressive and violent behaviour, namely, environmental factors and the attitude and behaviour of staff. From the perspective of the inpatients included in this study, aggressive and violent episodes are common and require intervention. Specific strategies for preventing such behaviour are proposed and it is recommended that these strategies be incorporated into the in-service training programmes of the staff of mental health facilities. These strategies could prevent, or reduce, aggressive and violent behaviour in in-patient facilities.

Focus on aggressive behaviour in mental illness.

Aggression is a behaviour with evolutionary origins, but in today’s society it is often both destructive and maladaptive. Increase of aggressive behaviour has been observed in a number of serious mental illnesses, and it represents a clinical challenge for mental healthcare provider. These phenomena can lead to harmful behaviours, including violence, thus representing a serious public health concern. Aggression is often a reason for psychiatric hospitalization, and it often leads to prolonged hospital stays, suffering by patients and their victims, and increased stigmatization. Moreover, it has an effect on healthcare use and costs in terms of longer length of stay, more readmissions and higher drug use. In this review, based on a selective search of 2010-2016 pertinent literature on PubMed, we analyze and summarize information from original articles, reviews, and book chapters about aggression and psychiatric disorders, discussing neurobiological basis and therapy of aggressive behaviour. A great challenge has been revealed regarding the neurobiology of aggression, and an integration of this body of knowledge will ultimately improve clinical diagnostics and therapeutic interventions. The great heterogeneity of aggressive behaviour still hampers our understanding of its causal mechanisms. Still, over the past years, the identification of specific subtypes of aggression has released possibilities for new and individualized treatment approaches. Neuroimaging studies may help to further elucidate the interrelationship between neurocognitive functioning, personality traits, and antisocial and violent behaviour. Recent studies point toward manipulable neurobehavioral targets and suggest that cognitive, pharmacological, neuromodulatory, and neurofeedback treatment approaches can be developed to ameliorate urgency and aggression in schizophrenia. These combined approaches could improve treatment efficacy. As current pharmacological and therapeutic interventions are

Applying social constructionism in the treatment of patients who are intractably aggressive.

PubMed

Caldwell, M F

1994-06-01

Interventions based on the philosophy of social constructionism can be used for the treatment of patients who are intractably aggressive. The interventions are aimed at disrupting common interactive patterns between the patient and treaters in the treatment milieu and replacing them with patterns that do not allow the intractable symptoms to disrupt treatment efforts. Two case examples illustrate the use of this approach with extremely violent inpatients with long histories of unsuccessful interventions. In both cases the treatment included discontinuing certain therapeutic or prosocial interventions; one case involved determining the patient's daily privilege level randomly. The author discusses the advantages and difficulties of such approaches, including the need for staff to reframe their own logical structure and to overcome resistance from different levels of the treatment system.

Iraq and Afghanistan War veterans were grouped by level of posttraumatic stress disorder (PTSD) symptomatology and compared on self-report measures of trait anger, hostility, and aggression. Veterans who screened positive for PTSD reported significantly greater anger and hostility than those in the subthreshold-PTSD and non-PTSD groups. Veterans in the subthreshold-PTSD group reported significantly greater anger and hostility than those in the non-PTSD group. The PTSD and subthreshold-PTSD groups did not differ with respect to aggression, though both groups were significantly more likely to have endorsed aggression than the non-PTSD group. These findings suggest that providers should screen for anger and aggression among Iraq and Afghanistan War veterans who exhibit symptoms of PTSD and incorporate relevant anger treatments into early intervention strategies.

Characteristics of aggression in a German psychiatric hospital and predictors of patients at risk.

Ketelsen, R; Zechert, C; Driessen, M; Schulz, M

2007-02-01

This study investigated the aggressive behaviour of all mentally ill patients within a whole psychiatric hospital with a catchment area of 325 000 inhabitants over a 1-year period (i) to assess the 1-year prevalence and characteristics of aggressive episodes and index inpatients, and (ii) to identify predictors of patients at risk by a multivariate approach. Staff Observation of Aggression Scale was used to assess aggressive behaviour. Characteristics of index inpatients were compared with those of non-index inpatients. Logistic regression analysis was applied to identify risk factors. A total of 171 out of 2210 admitted patients (7.7%) exhibited 441 aggressive incidents (1.7 incidents per bed per year). Logistic regression analyses revealed as major risk factors of aggression: diagnoses (organic brain syndromes OR = 3.6, schizophrenia OR = 2.9), poor psychosocial living conditions (OR = 2.2), and critical behaviour leading to involuntary admission (OR = 3.3). Predictors of aggressive behaviour can be useful to identify inpatients at risk. Nevertheless, additional situational determinants have to be recognized. Training for professionals should include preventive and de-escalating strategies to reduce the incidence of aggressive behaviour in psychiatric hospitals. The application of de-escalating interventions prior to admission might be effective in preventing aggressive behaviour during inpatient treatment especially for patients with severe mental disorders.

This paper emphasises the important role education and training may play in reducing the risk of staff being exposed to violent or aggressive experiences. Furthermore, the paper emphasises, explores and discusses well recognised theories relating to aggression development. These theories can be used to explain both organisational strategies designed to minimise aggression in the emergency department and situational factors contributing to the development of aggressive interactions.

The efficacy and tolerability of sodium valproate 2 x 240 mg compared to placebo were investigated in aggressive behavior in dementia. A randomized, placebo controlled, double-blind cross-over design. The trial included a baseline period (one week); a placebo period (three weeks); a wash-out period with placebo (one week); and a treatment period with sodium valproate (three weeks). A psychogeriatric short-stay ward at a psychiatric teaching hospital. Demented patients who met Patel's criteria for aggressive behavior and had a score of > or =3 on at least one of the items of the Social Dysfunction and Aggression scale-9 (SDAS-9). A fixed dose of sodium valproate 2 x 6 ml of a 40 mg/ml suspension (daily defined dose of 480 mg) was compared to placebo. Primary outcome variables were changes of the score of SDAS-9 and Clinical Global Impression scale (CGI) performed at the last week of each treatment period. Data of 42 patients (F=25 and M=17; age 80.4+/-6.8 years) were analyzed. Treatment with sodium valproate showed no differences compared to placebo on aggressive behavior. The mean plasma level of sodium valproate was 40.9+/-10.8 microg/ml. Regression analysis showed a trend for improvement between the plasma levels of sodium valproate and the SDAS-9 and the CGI scores. Adverse events were not related to the plasma levels of sodium valproate. Secondary outcome measurements showed significant improvement on restless, melancholic and anxious behavior; a trend for improvement was found on suspicious and dependent behavior. Possible limitations of this study are the low dose of sodium valproate, the relatively short treatment period (three weeks), and the absence of statistical corrections for multiple comparisons. This study showed no effect of sodium valproate 2 x 240 mg over placebo on aggressive behavior in dementia. Copyright 2002 John Wiley & Sons, Ltd.

Psychopathy and instrumental aggression: Evolutionary, neurobiological, and legal perspectives.

PubMed

Glenn, Andrea L; Raine, Adrian

2009-01-01

In the study of aggression, psychopathy represents a disorder that is of particular interest because it often involves aggression which is premeditated, emotionless, and instrumental in nature; this is especially true for more serious types of offenses. Such instrumental aggression is aimed at achieving a goal (e.g., to obtain resources such as money, or to gain status). Unlike the primarily reactive aggression observed in other disorders, psychopaths appear to engage in aggressive acts for the purpose of benefiting themselves. This is especially interesting in light of arguments that psychopathy may represent an alternative life-history strategy that is evolutionarily adaptive; behaviors such as aggression, risk-taking, manipulation, and promiscuous sexual behavior observed in psychopathy may be means by which psychopaths gain advantage over others. Recent neurobiological research supports the idea that abnormalities in brain regions key to emotion and morality may allow psychopaths to pursue such a strategy-psychopaths may not experience the social emotions such as empathy, guilt, and remorse that typically discourage instrumentally aggressive acts, and may even experience pleasure when committing these acts. Findings from brain imaging studies of psychopaths may have important implications for the law.

Predicting aggression in children with ADHD

PubMed Central

2014-01-01

Objective The present study uses structural equation modeling of latent traits to examine the extent to which family factors, cognitive factors and perceptions of rejection in mother-child relations differentially correlate with aggression at home and at school. Methods Data were collected from 476 school-age (7–15 years old) children with a diagnosis of ADHD who had previously shown different types of aggressive behavior, as well as from their parents and teachers. Structural equation modeling was used to examine the differential relationships between maternal rejection, family, cognitive factors and aggression in home and school settings. Results Family factors influenced aggression reported at home (.68) and at school (.44); maternal rejection seems to be related to aggression at home (.21). Cognitive factors influenced aggression reported at school (.-05) and at home (-.12). Conclusions Both genetic and environmental factors contribute to the development of aggressive behavior in ADHD. Identifying key risk factors will advance the development of appropriate clinical interventions and prevention strategies and will provide information to guide the targeting of resources to those children at highest risk.

Aggressive periodontitis is a great challenge to clinicians when providing orthodontic treatment because of the potential for progression of periodontal disease. In this article, we report the successful comprehensive orthodontic treatment of bimaxillary protrusion and severe crowding in an adult with generalized aggressive periodontitis. A woman, aged 22 years 7 months, with a chief complaint of incisal crowding was diagnosed with a skeletal Class I malocclusion associated with severe anterior crowding, possibly worsened by generalized aggressive periodontitis. In addition to a periodontal examination, a blood IgG antibody titer analysis and microbiologic examination for periodontal pathogens were used to diagnose the type of periodontal disease and determine the proper timing to initiate orthodontic treatment. The total active treatment period was 28 months, followed by periodontal prostheses and regeneration therapy. Consequently, satisfactory facial profile, occlusion, and periodontal health were maintained for at least 36 months. These results indicate that efficient screening is important for providing successful orthodontic treatment in patients with advanced periodontal disease. This report also demonstrates the diagnostic importance of blood IgG antibody titer assays and microbiologic examinations to detect periodontal pathogens.

Fisher, Caroline A; Brown, Anahita

Aggression is common in Huntington's disease. However, at present there are no standard guidelines for managing aggression in Huntington's sufferers due to a lack of empirical research. This paper presents a case study of the treatment of very high levels of aggression with sensory modulation and behaviour support intervention in a Huntington's sufferer. The client exhibited a range of aggressive behaviours, including physical aggression to people, furniture and objects, and verbal aggression. Following an eight week baseline phase, five weeks of sensory modulation intervention were employed. A behaviour support plan was then implemented as an adjunct to the sensory intervention, with aggressive behaviour systematically audited for a further 11 weeks. The results indicate a significant reduction in reported levels of aggression during the combined sensory modulation and behaviour support phase, compared to both the baseline and the sensory modulation therapy alone phases. This case study highlights the efficacy non-pharmacological interventions may have for reducing aggression in HD.

Aggression is defined as the act in which an individual intentionally harms or injures another of their own species. Antipsychotics are a form of treatment used in psychiatric routine. They have been used for decades in treatment of patients with aggressive behavior. Haloperidol and risperidone promote the control of psychiatric symptoms, through their respective mechanisms of action. Experimental models are obtained by behavioral, genetic, and pharmacological manipulations, and use a reduced number of animals. In this context, we applied the model of spontaneous aggression (MSA), originating the presence of highly aggressive mice (AgR) when reassembled in adulthood. We administered haloperidol and risperidone in escalating doses, for ten consecutive days. Using positive and negative control groups, we evaluated the effectiveness of these drugs and the reversal of the aggressive behavior, performing the tail suspension test (TST) and open field test (OFT) on 10th day of treatment and 10 days after its discontinuation. The results showed that both antipsychotic drugs were effective in AgR and reversed the aggressive phenotype, reducing the number of attacks by AgR and the extent of lesions in the subordinate mice (AgD) exposed to the pattern of aggressive behavior (PAB) of the aggressors. This conclusion is based on the reduction in the animals' motor and exploratory activity, and on the reversal of patterns of aggressive behavior. The association between the MSA and experiments with other therapeutic protocols and different antipsychotics can be an important methodology in the study of aggressive behavior in psychiatric patients.

Understanding Aggressive Behavior Across the Life Span

PubMed Central

Liu, Jianghong; Lewis, Gary; Evans, Lois

2012-01-01

Aggressive behavior is the observable manifestation of aggression and is often associated with developmental transitions and a range of medical and psychiatric diagnoses across the lifespan. As healthcare professionals involved in the medical and psychosocial care of patients from birth through death, nurses frequently encounter—and may serve as—both victims and perpetrators of aggressive behavior in the workplace. While the nursing literature has continually reported research on prevention and treatment approaches, less emphasis has been given to understanding the etiology, including contextual precipitants of aggressive behavior. This paper provides a brief review of the biological, social, and environmental risk factors that purportedly give rise to aggressive behavior. Further, many researchers have focused specifically on aggressive behavior in adolescence and adulthood. Less attention has been given to understanding the etiology of such behavior in young children and older adults. This paper emphasizes the unique risk factors for aggressive behavior across the developmental spectrum, including childhood, adolescence, adulthood, and late life. Appreciation of the risk factors of aggressive behavior, and, in particular, how they relate to age-specific manifestations, can aid nurses in better design and implementation of prevention and treatment programs.

Authors’ conclusions The authors consider that the body of evidence summarised in this review is insufficient to allow any firm conclusion to be drawn about the use of antiepileptic medication in the treatment of aggression and associated impulsivity. Four antiepileptics (valproate/ divalproex, carbamazepine, oxcarbazepine and phenytoin) were effective, compared to placebo, in reducing aggression in at least one study, although for three drugs (valproate, carbamazepine and phenytoin) at least one other study showed no statistically significant difference between treatment and control conditions. Side effects were more commonly noted for the intervention group although adverse effects were not well reported. Absence of information does not necessarily mean that the treatment is safe, nor that the potential gains from the medication necessarily balance the risk of an adverse event occurring. Further research is needed. PMID:20166067

2015-10-01

To investigate developmental trajectories in peer-reported aggressive behavior across the transition from elementary-to-middle school, and whether aggressive behavior trajectories were associated with friendship quality, friends' aggressive behavior, and the ways in which children think about their friendships. Participants included a community sample of 230 5 th grade children who were assessed when they made a transition from elementary-to-middle school (6 th grade). Peer nominations were used to assess the target child's and friend's aggressive behavior. Self- and friend reports were used to measure friendship quality; friendship understanding was assessed via a structured interview. General Growth Mixture Modeling (GGMM) revealed three distinct trajectories of peer-reported aggressive behavior across the school transition: low-stable, decreasing, and increasing. Adolescents' understanding of friendship formation differentiated the decreasing from the low-stable aggressive behavior trajectories, and the understanding of friendship trust differentiated the increasing from the low-stable aggressive and decreasing aggressive behavior trajectories. The findings indicated that a sophisticated understanding of friendship may serve as a protective factor for initially aggressive adolescents as they transition into middle school. Promoting a deepened understanding of friendship relations and their role in one's own and others' well-being may serve as an important prevention and intervention strategy to reduce aggressive behavior.

This experiment examined the effects of group composition on sow aggressive behaviour and welfare. Over 6 time replicates, 360 sows (parity 1-6) were mixed into groups (10 sows per pen, 1.8 m 2 /sow) composed of animals that were predicted to be aggressive (n = 18 pens) or groups composed of animals that were randomly selected (n = 18 pens). Predicted aggressive sows were selected based on a model-pig test that has been shown to be related to the aggressive behaviour of parity 2 sows when subsequently mixed in groups. Measurements were taken on aggression delivered post-mixing, and aggression delivered around feeding, fresh skin injuries and plasma cortisol concentrations at days 2 and 24 post-mixing. Live weight gain, litter size (born alive, total born, stillborn piglets), and farrowing rate were also recorded. Manipulating the group composition based on predicted sow aggressiveness had no effect (P > 0.05) on sow aggression delivered at mixing or around feeding, fresh injuries, cortisol, weight gain from day 2 to day 24, farrowing rate, or litter size. The lack of treatment effects in the present experiment could be attributed to (1) a failure of the model-pig test to predict aggression in older sows in groups, or (2) the dependence of the expression of the aggressive phenotype on factors such as social experience and characteristics (e.g., physical size and aggressive phenotype) of pen mates. This research draws attention to the intrinsic difficulties associated with predicting behaviour across contexts, particularly when the behaviour is highly dependent on interactions with conspecifics, and highlights the social complexities involved in the presentation of a behavioural phenotype.

Abstract Objectives: Previous “Treatment of Severe Childhood Aggression” (TOSCA) reports demonstrated that many children with severe physical aggression and attention-deficit/hyperactivity disorder (ADHD) responded well to two randomized treatments (parent training [PT]+stimulant+placebo = Basic vs. PT+stimulant+risperidone = Augmented) for 9 weeks. An important clinical question is whether these favorable outcomes are maintained over longer times. Methods: Clinical responders to the 9-week trial (n = 103/168), defined as Clinical Global Impressions (CGI)-Improvement of much/very much improved plus substantial reduction in parent ratings of disruptiveness, were followed another 12 weeks (21 weeks total) while remaining on blinded treatment. Outcome measures included Clinical Global Impressions scale, Nisonger Child Behavior Rating Form (NCBRF), other parent/teacher-rated scales, laboratory tests, clinician ratings of abnormal movement, and other adverse events (AEs). Results: Parent ratings of problem behavior showed minimal worsening of behavior from end of the 9-week acute trial (expected from regression to the mean after selecting best responders), but outcomes at Extension endpoint were meaningfully improved compared with acute study baseline. As expected, outcomes for Basic and Augmented treatment did not differ among these children selected for good clinical response. During Extension, more Augmented subjects had elevated prolactin; there were no clinically confirmed cases of tardive dyskinesia. Delayed sleep onset was the most frequent Basic AE. We also conducted a last-observation-carried-forward analysis, which included both nonresponders and responders. We found that, at the end of Extension, Augmented subjects had more improvement than Basic subjects on the NCBRF Positive Social subscale (p = 0.005; d = 0.44), the Antisocial Behavior Scale Reactive Aggression subscale (p = 0.03; d = 0.36), and marginally so on the

Longitudinal cohort studies and guidelines demonstrate that PSA ≥1 ng/mL in younger patients confer an increased risk of delayed prostate cancer (PC) death. In our institution we have used an aggressive biopsy strategy among younger patients with PSA of>1 ng/ml. Our objective was to determine the proportion of detected cancer and specifically, clinical significant cancer, with this strategy. The prostate biopsy (PB) database at Princess Margaret Cancer Centre was queried for patients younger than 50 who underwent a first PB between 2000 and 2016. We included only patients undergoing PB due to PSA>1 ng/mL, suspicious digital rectal examination, positive family history (PFH), or suspicious lesion on trans-rectal ultrasound. All clinical and pathological parameters were analyzed. Patients were stratified according to their specific PSA values. Multivariable logistic regression was performed to ascertain predictors of any PC diagnosis, and of clinically significant PC. Of 199 patients who met the inclusion criteria, 37 (19%) were diagnosed with PC and 8 (22%) had a Gleason score (GS)>7. Of those diagnosed with PC, 25 (68%) had a PSA>1.5 ng/ml and all men with GS>7 had PSA>1.5 ng/ml. Notably, 19 (51%) patients had PC exceeding Epstein criteria for active surveillance. Factors predicting PC included PFH, rising PSA and lower prostate volumes. Our results justify adopting an aggressive PB strategy for young men<50 years old with a PSA>1.5 ng/ml, while patients with PSAs<1.5 ng/ml are unlikely to have significant cancer. Special attention should be paid to patients with smaller prostates, and PFH. Copyright © 2018 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Oxytocin and Aggression.

PubMed

de Jong, Trynke R; Neumann, Inga D

2017-09-02

The neuropeptide oxytocin (OT) has a solid reputation as a facilitator of social interactions such as parental and pair bonding, trust, and empathy. The many results supporting a pro-social role of OT have generated the hypothesis that impairments in the endogenous OT system may lead to antisocial behavior, most notably social withdrawal or pathological aggression. If this is indeed the case, administration of exogenous OT could be the "serenic" treatment that psychiatrists have for decades been searching for.In the present review, we list and discuss the evidence for an endogenous "hypo-oxytocinergic state" underlying aggressive and antisocial behavior, derived from both animal and human studies. We furthermore examine the reported effects of synthetic OT administration on aggression in rodents and humans.Although the scientific findings listed in this review support, in broad lines, the link between a down-regulated or impaired OT system activity and increased aggression, the anti-aggressive effects of synthetic OT are less straightforward and require further research. The rather complex picture that emerges adds to the ongoing debate questioning the unidirectional pro-social role of OT, as well as the strength of the effects of intranasal OT administration in humans.

2018-05-01

Canine aggression occurring in the home can be a dangerous diagnosis with costly consequences to all members of the household. Management is a key modality in the treatment of canine aggression in the home. A thorough history will detail each trigger, target, and context and allow for the veterinary team to put together a comprehensive management plan. Management allows for the avoidance of future aggressive episodes and minimizes the risks associated with living with a patient with these diagnoses. Although risk cannot be mitigated 100%, thorough management can create a safe environment for the implementation of the behavior treatment plan. Copyright © 2017 Elsevier Inc. All rights reserved.

Intergroup Biases in Fear-induced Aggression

Mifune, Nobuhiro; Simunovic, Dora; Yamagishi, Toshio

2017-01-01

Using a recently created preemptive strike game (PSG) with 176 participants, we investigated if the motivations of spite and/or fear promotes aggression that requires a small cost to the aggressor and imposes a larger cost on the opponent, and confirmed the earlier finding that fear does but spite does not promote intergroup aggression when the groups are characterized as minimal groups; additionally, the rate of intergroup aggression did not vary according to the group membership of the opponent. The PSG represents a situation in which both the motivations of spite and of fear can logically drive players to choose an option of aggression against an opponent. Participants decide whether or not to attack another participant, who also has the same capability. The decision is made in real time, using a computer. We discuss theoretical implications of our findings on the evolutionary foundations of intragroup cooperation and intergroup aggression. The evolutionary model of intergroup aggression, or the parochial altruism model, posits that intragroup cooperation and intergroup aggression have co-evolved, and thus it predicts both intragroup cooperation and intergroup aggression to emerge even in a minimal group devoid of a history of intergroup relationships. The finding that only intragroup cooperation but not intergroup aggression emerged in the minimal group experiments strongly suggests that intergroup aggression involves a psychological mechanism that is independent from that of intragroup cooperation. We further discuss the implications of these findings on real-world politics and military strategy. PMID:28174553

2015-01-01

Objective To investigate developmental trajectories in peer-reported aggressive behavior across the transition from elementary-to-middle school, and whether aggressive behavior trajectories were associated with friendship quality, friends’ aggressive behavior, and the ways in which children think about their friendships. Method Participants included a community sample of 230 5th grade children who were assessed when they made a transition from elementary-to-middle school (6th grade). Peer nominations were used to assess the target child’s and friend’s aggressive behavior. Self- and friend reports were used to measure friendship quality; friendship understanding was assessed via a structured interview. Results General Growth Mixture Modeling (GGMM) revealed three distinct trajectories of peer-reported aggressive behavior across the school transition: low-stable, decreasing, and increasing. Adolescents’ understanding of friendship formation differentiated the decreasing from the low-stable aggressive behavior trajectories, and the understanding of friendship trust differentiated the increasing from the low-stable aggressive and decreasing aggressive behavior trajectories. Conclusions The findings indicated that a sophisticated understanding of friendship may serve as a protective factor for initially aggressive adolescents as they transition into middle school. Promoting a deepened understanding of friendship relations and their role in one’s own and others’ well-being may serve as an important prevention and intervention strategy to reduce aggressive behavior.

2011-02-01

Vertebral hemangiomas (VHs) are frequently asymptomatic lesions found incidentally during investigations for other spinal problems. Symptomatic VHs are less common, and there are few reports of compressive VHs in the literature. VHs with aggressive behavior present with low signal intensity on T1-weighted and high signal intensity on T2-weighted MRI. We present a case series of four patients with compressive VH, all of whom were neurologically compromised. Each of the four patients underwent preoperative arterial embolization followed by surgical treatment of their VHs. All patients recovered normal motor function after surgery. At follow-up (average 53 months), one patient had a recurrent tumor requiring reoperation and radiotherapy. Although it is rare, aggressive VH can be a devastating condition. Total surgical resection or subtotal resection with radiotherapy may be warranted. Copyright © 2010 Elsevier Ltd. All rights reserved.

Adult T-cell leukemia-lymphoma is a distinct type of peripheral T-cell lymphoma caused by human T-cell lymphotropic virus type I. Although allogeneic stem cell transplantation after chemotherapy is a recommended treatment option for patients with aggressive adult T-cell leukemia-lymphoma, there is no consensus about indications for allogeneic stem cell transplantation because there is no established risk stratification system for transplant eligible patients. We conducted a nationwide survey of patients with aggressive adult T-cell leukemia-lymphoma in order to construct a new, large database that includes 1,792 patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who were diagnosed between 2000 and 2013 and received intensive first-line chemotherapy. We randomly divided patients into two groups (training and validation sets). Acute type, poor performance status, high soluble interleukin-2 receptor levels (> 5,000 U/mL), high adjusted calcium levels (≥ 12 mg/dL), and high C-reactive protein levels (≥ 2.5 mg/dL) were independent adverse prognostic factors used in the training set. We used these five variables to divide patients into three risk groups. In the validation set, median overall survival for the low-, intermediate-, and high-risk groups was 626 days, 322 days, and 197 days, respectively. In the intermediate- and high-risk groups, transplanted recipients had significantly better overall survival than non-transplanted patients. We developed a promising new risk stratification system to identify patients aged 70 years or younger with aggressive adult T-cell leukemia-lymphoma who may benefit from upfront allogeneic stem cell transplantation. Prospective studies are warranted to confirm the benefit of this treatment strategy. Copyright© 2017 Ferrata Storti Foundation.

[Therapeutic strategies against myasthenia gravis].

2013-05-01

Many patients with myasthenia gravis (MG) still find it difficult to maintain daily activities due to chronic residual fatigability and long-term side effects of oral corticosteroids, since full remission is not common. Our analysis demonstrated that disease severity, oral corticosteroids, and depressive state are the major factors negatively associated with QOL, and that QOL of MM status patients taking < or = 5 mg prednisolne/day is identically good as that seen in CSR and is a target of treatment. In order to achieve early MM or better status with prednisolne < or = 5 mg/day, we advocate the early aggressive treatment strategy that can achieve early improvement by performing an aggressive therapy using combined treatment with plasmapheresis and high-dose intravenous methylprednisolone and then maintain an improved status using low-dose oral corticosteroids and calcineurin inhibitors.

To study the prevalence, nature and determinants of aggression among inpatients with acquired brain injury. Patients with acquired brain injury often have difficulty in controlling their aggressive impulses. A prospective observational study design. By means of the Staff Observation Aggression Scale-Revised, the prevalence, nature and severity of aggressive behaviour of inpatients with acquired brain injury was assessed on a neuropsychiatric treatment ward with 45 beds. Additional data on patient-related variables were gathered from the patients' files. In total, 388 aggressive incidents were recorded over 17 weeks. Of a total of 57 patients included, 24 (42%) patients had engaged in aggressive behaviour on one or more occasions. A relatively small proportion of patients (n=8; 14%) was found to be responsible for the majority of incidents (n=332; 86%). The vast majority of aggression incidents (n=270; 70%) were directly preceded by interactions between patients and nursing staff. In line with this, most incidents occurred at times of high contact intensity. Aggressive behaviour was associated with male gender, length of stay at the ward, legal status and hypoxia as the cause of brain injury. Aggression was found to be highly prevalent among inpatients with acquired brain injury. The results suggest that for the prevention of aggression on the ward, it may be highly effective to develop individually tailored interventions for the subgroup with serious aggression problems. Insight into the frequency, nature and determinants of aggressive behaviour in inpatients with acquired brain injury provides nurses with tools for the prevention and treatment of aggressive behaviour. © 2011 Blackwell Publishing Ltd.

Complete recovery from undertreated Wernicke-Korsakoff syndrome following aggressive thiamine treatment.

2010-01-01

Wernicke-Korsakoff syndrome (WKS) is a neuropsychiatric condition which results from thiamine deficiency, most commonly due to alcohol abuse. The prognosis of WKS is poor and its outcome depends mainly on prompt treatment. A 52-year-old male with a ten-year history of heavy alcohol abuse was admitted in hospital and treated for WKS. Ataxic and oculomotor symptoms promptly reversed following standard treatment but no change was observed in higher mental functioning. Although the protracted WK symptoms made the patient's improvement unlikely, aggressive treatment with thiamine (600 mg/day orally and 300 mg/day intramuscularly) fully reversed the condition within two months. Even though prolongation of undertreatment of WKS typically precludes significant improvement of symptoms due to irreversible damage of the brain, at least in some cases, higher thiamine doses (over 500 mg/day) for a longer period (at least three months) than usually recommended should be tried.

Cellulose degradation: a therapeutic strategy in the improved treatment of Acanthamoeba infections.

PubMed

Lakhundi, Sahreena; Siddiqui, Ruqaiyyah; Khan, Naveed Ahmed

2015-01-14

Acanthamoeba is an opportunistic free-living amoeba that can cause blinding keratitis and fatal brain infection. Early diagnosis, followed by aggressive treatment is a pre-requisite in the successful treatment but even then the prognosis remains poor. A major drawback during the course of treatment is the ability of the amoeba to enclose itself within a shell (a process known as encystment), making it resistant to chemotherapeutic agents. As the cyst wall is partly made of cellulose, thus cellulose degradation offers a potential therapeutic strategy in the effective targeting of trophozoite encased within the cyst walls. Here, we present a comprehensive report on the structure of cellulose and cellulases, as well as known cellulose degradation mechanisms with an eye to target the Acanthamoeba cyst wall. The disruption of the cyst wall will make amoeba (concealed within) susceptible to chemotherapeutic agents, and at the very least inhibition of the excystment process will impede infection recurrence, as we bring these promising drug targets into focus so that they can be explored to their fullest.

Female competition and aggression: interdisciplinary perspectives

PubMed Central

Stockley, Paula; Campbell, Anne

2013-01-01

This paper introduces a Theme Issue combining interdisciplinary perspectives in the study of female competition and aggression. Despite a history of being largely overlooked, evidence is now accumulating for the widespread evolutionary significance of female competition. Here, we provide a synthesis of contributions to this Theme Issue on humans and other vertebrates, and highlight directions for future research. Females compete for resources needed to survive and reproduce, and for preferred mates. Although female aggression takes diverse forms, under most circumstances relatively low-risk competitive strategies are favoured, most probably due to constraints of offspring production and care. In social species, dominance relationships and threats of punishment can resolve social conflict without resort to direct aggression, and coalitions or alliances may reduce risk of retaliation. Consistent with these trends, indirect aggression is a low cost but effective form of competition among young women. Costs are also minimized by flexibility in expression of competitive traits, with aggressive behaviour and competitive signalling tailored to social and ecological conditions. Future research on female competition and the proximate mediators of female aggression will be greatly enhanced by opportunities for interdisciplinary exchange, as evidenced by contributions to this Theme Issue.

Amann, Birgit H.

2016-01-01

Abstract Objective: This article examines the characteristics of impulsive aggression (IA) as a comorbidity in children and adolescents with attention-deficit/hyperactivity disorder (ADHD), focusing on its incidence, impact on ADHD outcomes, need for timely intervention, and limitations of current treatment practices. Methods: Relevant literature was retrieved with electronic searches in PubMed and PsycINFO using the search strategy of “ADHD OR attention deficit hyperactivity disorder” AND “impulsive aggression OR reactive aggression OR hostile aggression OR overt aggression” AND “pediatric OR childhood OR children OR pre-adolescent OR adolescent” with separate searches using review OR clinical trial as search limits. Key articles published before the 2007 Expert Consensus Report on IA were identified using citation analysis. Results: More than 50% of preadolescents with ADHD combined subtype reportedly display clinically significant aggression, with impulsive aggression being the predominant subtype. Impulsive aggression is strongly predictive of a highly unfavorable developmental trajectory characterized by the potential for persistent ADHD, increasing psychosocial burden, accumulating comorbidities, serious lifelong functional deficits across a broad range of domains, delinquency/criminality, and adult antisocial behavior. Impulsive aggression, which triggers peer rejection and a vicious cycle of escalating dysfunction, may be a key factor in unfavorable psychosocial outcomes attributed to ADHD. Because severe aggressive behavior does not remit in many children when treated with primary ADHD therapy (i.e., stimulants and behavioral therapy), a common practice is to add medication of a different class to specifically target aggressive behavior. Conclusions: Impulsive aggression in children and adolescents with ADHD is a serious clinical and public health problem. Although adjunctive therapy with an aggression-targeted agent is widely recommended when

2016-02-01

Anger, irritability, and aggression are among the most common reasons for child mental health referrals. This review is focused on two forms of behavioral interventions for these behavioral problems: Parent management training (PMT) and cognitive-behavioral therapy (CBT). First, we provide an overview of anger/irritability and aggression as the treatment targets of behavioral interventions, followed by a discussion of the general principles and techniques of these treatment modalities. Then we discuss our current work concerning the transdiagnostic approach to CBT for anger, irritability, and aggression. PMT is aimed at improving aversive patterns of family interactions that engender children's disruptive behavior. CBT targets deficits in emotion regulation and social problem-solving that are associated with aggressive behavior. Both forms of treatment have received extensive support in randomized controlled trials. Given that anger/irritability and aggressive behavior are common in children with a variety of psychiatric diagnoses, a transdiagnostic approach to CBT for anger and aggression is described in detail. PMT and CBT have been well studied in randomized controlled trials in children with disruptive behavior disorders, and studies of transdiagnostic approaches to CBT for anger and aggression are currently underway. More work is needed to develop treatments for other types of aggressive behavior (e.g., relational aggression) that have been relatively neglected in clinical research. The role of callous-unemotional traits in response to behavioral interventions and treatment of irritability in children with anxiety and mood disorders also warrants further investigation.

SOS, the formidable strategy of bacteria against aggressions.

PubMed

Baharoglu, Zeynep; Mazel, Didier

2014-11-01

The presence of an abnormal amount of single-stranded DNA in the bacterial cell constitutes a genotoxic alarm signal that induces the SOS response, a broad regulatory network found in most bacterial species to address DNA damage. The aim of this review was to point out that beyond being a repair process, SOS induction leads to a very strong but transient response to genotoxic stress, during which bacteria can rearrange and mutate their genome, induce several phenotypic changes through differential regulation of genes, and sometimes acquire characteristics that potentiate bacterial survival and adaptation to changing environments. We review here the causes and consequences of SOS induction, but also how this response can be modulated under various circumstances and how it is connected to the network of other important stress responses. In the first section, we review articles describing the induction of the SOS response at the molecular level. The second section discusses consequences of this induction in terms of DNA repair, changes in the genome and gene expression, and sharing of genomic information, with their effects on the bacteria's life and evolution. The third section is about the fine tuning of this response to fit with the bacteria's 'needs'. Finally, we discuss recent findings linking the SOS response to other stress responses. Under these perspectives, SOS can be perceived as a powerful bacterial strategy against aggressions. © 2014 Federation of European Microbiological Societies. Published by John Wiley & Sons Ltd.

Feline aggression toward people is a common and potentially dangerous problem. Proper diagnosis of the underlying cause of the aggression is key in effective treatment. A complete history, including information on the people in the home, other pets, and specific incidents, is necessary to make this diagnosis. A comprehensive treatment plan typically includes management, enhancement of the cat's living environment, techniques for replacing the aggressive behavior with more appropriate behaviors, and, potentially, medication. The treatment plan must reflect the abilities and commitment of the owner. Copyright © 2014 Elsevier Inc. All rights reserved.

Abusive early child rearing and early childhood aggression.

PubMed

Herrenkohl, R C; Russo, M J

2001-02-01

Childhood aggression is significant for children, their families, and the society because aggressive children often become violent adolescents. This article examines the relationship between maltreatment and early childhood aggression. Data are from a longitudinal study of maltreated and nonmaltreated children assessed as preschoolers and again at school age. The dependent variable is the child's teacher's rating of aggression at school age. The independent variables are from preschool and school age observations of the mother-child interaction and the mother's report of physical discipline practices. Using structural equation modeling, harshness of interaction at preschool age but not school age and severity of physical discipline at school age but not preschool age, relate to aggression at school age. Results suggest a difference in the developmental stage at which different features of harsh child rearing exert their influence. Strategies for intervening to prevent the development of childhood aggression are suggested.

Recent Progress in Therapeutic Treatments and Screening Strategies for the Prevention and Treatment of HPV-Associated Head and Neck Cancer

Whang, Sonia N.; Filippova, Maria; Duerksen-Hughes, Penelope

2015-01-01

The rise in human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) has elicited significant interest in the role of high-risk HPV in tumorigenesis. Because patients with HPV-positive HNSCC have better prognoses than do their HPV-negative counterparts, current therapeutic strategies for HPV+ HNSCC are increasingly considered to be overly aggressive, highlighting a need for customized treatment guidelines for this cohort. Additional issues include the unmet need for a reliable screening strategy for HNSCC, as well as the ongoing assessment of the efficacy of prophylactic vaccines for the prevention of HPV infections in the head and neck regions. This review also outlines a number of emerging prospects for therapeutic vaccines, as well as for targeted, molecular-based therapies for HPV-associated head and neck cancers. Overall, the future for developing novel and effective therapeutic agents for HPV-associated head and neck tumors is promising; continued progress is critical in order to meet the challenges posed by the growing epidemic.

Add-on perampanel and aggressive behaviour in severe drug-resistant focal epilepsies.

PubMed

Juhl, S; Rubboli, G

This study aimed to investigate the incidence of aggressiveness in patients with severe drug-refractory focal epilepsy (DRE) who started perampanel (PER) as add-on treatment, and to identify possible predisposing factors. Data on 49 consecutive patients with severe DRE who initiated PER were retrospectively collected. Twelve of the 49 patients experienced aggressiveness as adverse event related to PER treatment, one third of them on low (2-4 mg/day) PER dosages. PER was discontinued in 10/12 patients because of aggressive behaviors. Aggressiveness could appear after several months or even more than one year of PER treatment. One third of patients with PER-related aggressiveness had intellectual disabilities and 5/12 patients took levetiracetam as a concomitant antiepileptic drug. Our study suggests that the occurrence of aggressive behaviors in patients with severe DRE is not uncommon during PER treatment and that it may occur after months or even years of treatment with a stable dosage, requiring PER discontinuation in the great majority of patients.

A COGNITIVE PERSPECTIVE ON AGGRESSIVE MIMICRY

PubMed Central

JACKSON, ROBERT R.; CROSS, FIONA R.

2013-01-01

We use the term ‘aggressive mimic’ for predators that communicate with their prey by making signals to indirectly manipulate prey behaviour. For understanding why the aggressive mimic’s signals work, it is important to appreciate that these signals interface with the prey’s perceptual system, and that the aggressive mimic can be envisaged as playing mind games with its prey. Examples of aggressive mimicry vary from instances in which specifying a model is straight forward to instances where a concise characterisation of the model is difficult. However, the less straightforward examples of aggressive mimicry may be the more interesting examples in the context of animal cognition. In particular, there are spiders that prey on other spiders by entering their prey’s web and making signals. Web invasion brings about especially intimate contact with their prey’s perceptual system because the prey spider’s web is an important component of the prey spider’s sensory apparatus. For the web-invading spider, often there is also a large element of risk when practising aggressive mimicry because the intended prey is also a potential predator. This element of risk, combined with exceptionally intimate interfacing with prey perceptual systems, may have favoured the web-invading aggressive mimic’s strategy becoming strikingly cognitive in character. Yet a high level of flexibility may be widespread among aggressive mimics in general and, on the whole, we propose that research on aggressive mimicry holds exceptional potential for advancing our understanding of animal cognition.

Background: Youth indulgence themselves in various aggressive behaviors leading to significant psychosocial dysfunctions. The present study assesses the prevalence of aggression among youth and to assess the risk factors of aggression among youth. Materials and Methods: Anger Data sheet, Resilience Scale and Buss-Perry Aggression Scale, were administered on 5476 participants using survey design. Data was collected from different communities (college, residential, apartments and workplace) of Bangalore, Jammu, Indore, Kerala, Rajasthan, Sikkim and Delhi. 47% were female and 53% were male. The mean age of the sample was 20.2 years. Comparative analysis was carried out by Pearson correlation coefficient and Chi-square was also carried out. Results: About 17.7% of the youth has high mean aggression score on Buss-Perry Aggression Scale. Males have high mean score on aggression than females. Males experienced more verbal aggression, physical aggression and anger than females. Younger age group (16-19 years) experienced more aggression than older age group (20-26 years). The risk factors of the youth aggressions were identified as physical abuse in childhood, substance abuse such as alcohol and tobacco, negative peer influence, family violence, academic disturbance, psychological problems attention deficit-hyperactivity disorder, suspicious, loneliness, mood disturbance, negative childhood experience and TV and media. Conclusion: The study document, the presence of correlates of risk factors of aggression among youth and implies usages of management strategies to help them to handle aggression. PMID:24701010

To assess whether a multimedia program can affect counseling behavior related to one of the strongest risk factors for violence later in life, persistent early childhood aggression. The design was a controlled trial with unobtrusive measurement in a clinic setting. A researcher, pretending to be the mother of a 2 ½ year old boy, called 19 pediatric residents during clinic hours and requested advice on how to manage her child's persistently hurtful behavior. The intervention was a 40-min lecture focusing on a multimedia program, Play Nicely, which teaches accepted strategies for managing aggression in young children ages 1-7 years. Residents' responses were blindly assessed to determine the treatment effect of the intervention. Compared with the control group (C), residents in the intervention (I) group were more likely to recommend setting the rule (I: 100% vs. C: 31%, p = .01), redirecting (I: 83% vs. C: 8%, p = .003), promoting empathy (I: 50% vs. C: 0%, p = .02), and more likely to discourage the use of physical punishment (I: 83% vs. C: 31%). These are the primary strategies encouraged by the intervention. The magnitude of the effect size was very large for each of these three strategies, ranging from d = 1.1 to 2.3. A brief intervention can improve the counseling behavior of primary care physicians regarding persistent childhood aggression. The findings have implications for child abuse prevention, violence prevention, medical education, and how to improve anticipatory guidance within primary care.

Aggression and suicidality are two serious public health concerns among U.S. veterans that can co-occur and share many overlapping risk factors. The current study aims to elucidate the contribution of posttraumatic stress disorder (PTSD) symptom clusters defined by a five-factor model and alcohol misuse in predicting aggression and suicide attempts among veterans entering residential treatment for PTSD. Participants were 2570 U.S. veterans across 35 Veterans Health Administration sites. Multinomial logistic regression models were used to identify correlates of aggression only (n = 1471; 57.2%), suicide attempts only (n = 41; 1.6%), co-occurring aggression and suicide attempts (n = 202; 7.9%), and neither behavior (n = 856; 33.3%) over the past four months. When compared to veterans endorsing neither behavior, greater PTSD re-experiencing symptoms were related to suicide attempts (odds ratio [OR] = 1.58, 95% confidence interval [CI] = 1.09-2.30), aggression (OR = 1.13, 95% CI = 1.02-1.26), and co-occurring aggression and suicide (OR = 1.38, 95% CI = 1.13-1.68), and higher PTSD dysphoric arousal symptoms and alcohol misuse symptoms were related to aggression (OR = 1.54, 95% CI = 1.38-1.71; OR = 1.30, 95% CI = 1.18-1.44, respectively) and co-occurring aggression and suicide (OR = 1.66, 95% CI = 1.35-2.04; OR = 1.50, 95% CI = 1.28-1.75, respectively). Our findings suggest that assessment of PTSD symptom clusters and alcohol misuse can potentially help to identify veterans who endorse suicide attempts, aggression, or both concurrently. These results have important implications for risk assessment and treatment planning with U.S. veterans seeking care for PTSD. Published by Elsevier Ltd.

Abstract Objective: Anger, irritability, and aggression are among the most common reasons for child mental health referrals. This review is focused on two forms of behavioral interventions for these behavioral problems: Parent management training (PMT) and cognitive-behavioral therapy (CBT). Methods: First, we provide an overview of anger/irritability and aggression as the treatment targets of behavioral interventions, followed by a discussion of the general principles and techniques of these treatment modalities. Then we discuss our current work concerning the transdiagnostic approach to CBT for anger, irritability, and aggression. Results: PMT is aimed at improving aversive patterns of family interactions that engender children's disruptive behavior. CBT targets deficits in emotion regulation and social problem-solving that are associated with aggressive behavior. Both forms of treatment have received extensive support in randomized controlled trials. Given that anger/irritability and aggressive behavior are common in children with a variety of psychiatric diagnoses, a transdiagnostic approach to CBT for anger and aggression is described in detail. Conclusions: PMT and CBT have been well studied in randomized controlled trials in children with disruptive behavior disorders, and studies of transdiagnostic approaches to CBT for anger and aggression are currently underway. More work is needed to develop treatments for other types of aggressive behavior (e.g., relational aggression) that have been relatively neglected in clinical research. The role of callous-unemotional traits in response to behavioral interventions and treatment of irritability in children with anxiety and mood disorders also warrants further investigation.

Individuals with fragile X syndrome (FXS), especially men, have long been described as presenting with significant behavioural challenges. Despite this known aspect of the phenotype, there has been little research exploring the prevalence, frequency, nature or consequences of aggressive behaviour in FXS. This study used survey methodology to gather caregiver reports on the types, frequency and severity of aggressive behaviour in 774 individuals with FXS. Based on caregiver report, nearly all (>90%) male and female individuals were reported to have engaged in some aggression over the previous 12 months, with a third of male cases and slightly fewer than 20% of female cases being described as engaging in moderate to severe aggression or being diagnosed or treated for aggression. Further, aggressive behaviours in male individuals were serious enough that 30% had caused injuries to caregivers and 22% had caused injuries to peers or friends. Sensory issues and hyperactivity were significant predictors of the frequency of aggressive acts, while sensory issues and anxiety were predictive of the severity of aggression. Traditional behaviour management techniques as well as medication was described as the most common and successful treatment options. Aggressive behaviours are a significant concern for a subsample of both male and female individuals with FXS. Given that sensory concerns were predictive of both the frequency and the severity of aggression suggests these behaviours may be a reactive means of escaping uncomfortable situations. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

This longitudinal study examines the association between child gender and child aggression via parents' physical control, moderated by parents' gender-role stereotypes in a sample of 299 two-parent families with a 3-year-old child in the Netherlands. Fathers with strong stereotypical gender-role attitudes and mothers were observed to use more physical control strategies with boys than with girls, whereas fathers with strong counterstereotypical attitudes toward gender roles used more physical control with girls than with boys. Moreover, when fathers had strong attitudes toward gender roles (stereotypical or counterstereotypical), their differential treatment of boys and girls completely accounted for the gender differences in children's aggressive behavior a year later. Mothers' gender-differentiated parenting practices were unrelated to gender differences in child aggression. © 2016 The Authors.

Haloperidol for long-term aggression in psychosis.

PubMed

Khushu, Abha; Powney, Melanie J

Psychotic disorders can lead some people to become agitated. Characterised by restlessness, excitability and irritability, this can result in verbal and physically aggressive behaviour - and both can be prolonged. Aggression within the psychiatric setting imposes a significant challenge to clinicians and risk to service users; it is a frequent cause for admission to inpatient facilities. If people continue to be aggressive it can lengthen hospitalisation. Haloperidol is used to treat people with long-term aggression. To examine whether haloperidol alone, administered orally, intramuscularly or intravenously, is an effective treatment for long-term/persistent aggression in psychosis. We searched the Cochrane Schizophrenia Group Trials Register (July 2011 and April 2015). We included randomised controlled trials (RCT) or double blind trials (implying randomisation) with useable data comparing haloperidol with another drug or placebo for people with psychosis and long-term/persistent aggression. One review author (AK) extracted data. For dichotomous data, one review author (AK) calculated risk ratios (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a fixed-effect model. One review author (AK) assessed risk of bias for included studies and created a 'Summary of findings' table using GRADE. We have no good-quality evidence of the absolute effectiveness of haloperidol for people with long-term aggression. One study randomising 110 chronically aggressive people to three different antipsychotic drugs met the inclusion criteria. When haloperidol was compared with olanzapine or clozapine, skewed data (n=83) at high risk of bias suggested some advantage in terms of scale scores of unclear clinical meaning for olanzapine/clozapine for 'total aggression'. Data were available for only one other outcome, leaving the study early. When compared with other antipsychotic drugs, people allocated to haloperidol were no more likely to leave the study

The role of aggression-related early maladaptive schemas and schema modes in aggression in a prisoner sample.

Contemporary social-cognitive aggression theory and extant empirical research highlights the relationship between certain Early Maladaptive Schemas (EMSs) and aggression in offenders. To date, the related construct of schema modes, which presents a comprehensive and integrated schema unit, has received scant empirical attention. Furthermore, EMSs and schema modes have yet to be examined concurrently with respect to aggressive behavior. This study examined associations between EMSs, schema modes, and aggression in an offender sample. Two hundred and eight adult male prisoners completed self-report psychological tests measuring their histories of aggression, EMSs, and schema modes. Regression analyses revealed that EMSs were significantly associated with aggression but did not account for a unique portion of variance once the effects of schema modes were taken into account. Three schema modes, Enraged Child, Impulsive Child, and Bully and Attack, significantly predicted aggression. These findings support the proposition that schema modes characterized by escalating states of anger, rage, and impulsivity characterize aggressive offenders. In this regard, we call attention to the need to include schema modes in contemporary social-cognitive aggression theories, and suggest that systematic assessment and treatment of schema modes has the potential to enhance outcomes with violent offenders. © 2018 Wiley Periodicals, Inc.

Proactive and Early Aggressive Wound Management: A Shift in Strategy Developed by a Consensus Panel Examining the Current Science, Prevention, and Management of Acute and Chronic Wounds.

Normal wound healing is accomplished through a series of well-coordinated, progressive events with overlapping phases. Chronic wounds are described as not progressing to healing or not being responsive to management in a timely manner. A consensus panel of multidisciplinary wound care professionals was assembled to (1) educate wound care practitioners by identifying key principles of the basic science of chronic wound pathophysiology, highlighting the impact of metalloproteinases and biofilms, as well as the role of the extracellular matrix; and (2) equip practitioners with a systematic strategy for the prevention and healing of acute injuries and chronic wounds based upon scientific evidence and the panel members' expertise. An algorithm is presented that represents a shift in strategy to proactive and early aggressive wound management. With proactive management, adjunct therapies are applied preemptively to acute injuries to reduce wound duration and risk of chronicity. For existing chronic wounds, early aggressive wound management is employed to break the pathophysiology cycle and drive wounds toward healing. Reducing bioburden through debridement and bioburden management and using collagen dressings to balance protease activity prior to the use of advanced modalities may enhance their effectiveness. This early aggressive wound management strategy is recommended for patients at high risk for chronic wound development at a minimum. In their own practices, the panel members apply this systematic strategy for all patients presenting with acute injuries or chronic wounds.

Aggressive behaviour by people with dementia in residential care settings: a review.

PubMed

Pulsford, D; Duxbury, J

2006-10-01

This paper considers the phenomenon of aggressive behaviour perpetrated by people with dementia in residential care settings. Aggressive behaviour is defined in the context of people with dementia, and the problem of ascertaining the incidence of aggression among people with dementia is discussed. The emotional impact of assaults on nurses and other professionals is highlighted, and differing perspectives on the causation of aggressive behaviour are considered. Management strategies derived from the physical/pharmacological; environment management; behaviour modification and person-centred approaches are reviewed. Our conclusion is that while certain strategies appear to reflect good and common sense practice, in particular those deriving from the person-centred approach, there is no clear research evidence for the general effectiveness of any one management approach, and each has drawbacks of a practical or ethical nature. There is also little empirical information about how professional carers actually manage aggressive behaviour in practice.

Pharmacology and pharmacogenetics of pediatric ADHD with associated aggression: a review.

PubMed

Patel, Bianca D; Barzman, Drew H

2013-12-01

Attention deficit hyperactivity disorder (ADHD) is often associated with symptoms of aggression in children and adolescents. Clinically, this is complex because aggression can be from hyperactivity and impulsivity, or could be a distinct symptom from a comorbid diagnosis. Past research has recommended first treating the primary disorder of ADHD. Stimulants are the most common treatment for pediatric ADHD, which can be helpful in decreasing aggressive behaviors. Alpha-adrenergic agonists and atomoxetine (ATX) are non-stimulant medications for ADHD and aggression, but more research is necessary to compare these drugs to stimulants. If aggressive symptoms do not improve from treating the primary disorder, aggression can be treated separately. Risperidone, lithium, valproic acid, clonidine, and guanfacine have shown positive results in reducing aggression, but studies including children with aggression and ADHD are limited. The variability in treatment tolerability in patients has stimulated research in pharmacogenetics for ADHD. Although this field is still emerging, research has found evidence supporting a link between the response rate of methylphenidate and the dopamine transporter (DAT1) and a link between the metabolism rate of atomoxetine and hepatic cytochrome 450 isozymes. Pharmacogenetics may be relevant to ADHD and associated aggression. Further research in pharmacogenetics will strive to identify patterns of genetic variations that can tailor individual treatments.

Feedback to semi-professional counselors in treating child aggression.

To investigate the impact of outcome feedback provided to semi-professional counselors of children and adolescents at risk for aggressive behavior, following group treatment. Participants included 230 aggressive children and adolescents and 64 educators in a quasi-experimental design of 3 conditions: experimental group with feedback, experimental group without feedback, and control group (no treatment). The current study employed a feedback system based on self-report aggression scores measured after each session, provided to teachers, including an alert system and weekly follow-up group support. Outcomes were more favorable for the treatment children than the control group, but feedback had no impact on the results. Outcome feedback provided to group therapists does not have an effect on children and adolescents' reduction of aggression. Further research is needed to identify possible reasons for failure to show feedback effect.

Brain structures and neurotransmitters regulating aggression in cats: implications for human aggression.

PubMed

Gregg, T R; Siegel, A

2001-01-01

1. Violence and aggression are major public health problems. 2. The authors have used techniques of electrical brain stimulation, anatomical-immunohistochemical techniques, and behavioral pharmacology to investigate the neural systems and circuits underlying aggressive behavior in the cat. 3. The medial hypothalamus and midbrain periaqueductal gray are the most important structures mediating defensive rage behavior, and the perifornical lateral hypothalamus clearly mediates predatory attack behavior. The hippocampus, amygdala, bed nucleus of the stria terminalis, septal area, cingulate gyrus, and prefrontal cortex project to these structures directly or indirectly and thus can modulate the intensity of attack and rage. 4. Evidence suggests that several neurotransmitters facilitate defensive rage within the PAG and medial hypothalamus, including glutamate, Substance P, and cholecystokinin, and that opioid peptides suppress it; these effects usually depend on the subtype of receptor that is activated. 5. A key recent discovery was a GABAergic projection that may underlie the often-observed reciprocally inhibitory relationship between these two forms of aggression. 6. Recently, Substance P has come under scrutiny as a possible key neurotransmitter involved in defensive rage, and the mechanism by which it plays a role in aggression and rage is under investigation. 7. It is hoped that this line of research will provide a better understanding of the neural mechanisms and substrates regulating aggression and rage and thus establish a rational basis for treatment of disorders associated with these forms of aggression.

Gendered Perceptions of Drugs, Aggression, and Violence

Objective Drug use has been linked empirically with aggression and violence among youth in national and State of Hawai‘i samples. In addition, aggression and violence appear to be gendered experiences perceived differently by girls and boys. This paper explores the intersection of drug offers/drug refusals with aggression and violence with specific attention paid to gendered perceptions of drug use situations as a context for aggression and violence. Methods A qualitative study, in which fourteen sex-specific focus group discussions were held, focused on rural Native Hawaiian middle school students (N=64). Students were asked to discuss drug refusal strategies in a variety of drug offer contexts. Feminist theories and approaches were used to examine the role of aggression and violence in drug refusal as perceived by Native Hawaiian girls as compared to boys. Results Girls and boys differed in their perceptions of aggression and violence in drug offer situations, initially as evidenced by the extent to which the girls groups focused on the intersection of drugs and violence. Further, qualitative analyses reflected gender norms and stereotypes about aggression and violence perpetration, and girls' apparently unique concerns about sexual violence victimization. Conclusions Implications are discussed in terms of prevention research and practice, specifically in terms of school-based prevention curricula. PMID:27456534

Aggressive behaviour is commonly encountered in the general practice setting and can often be de-escalated using good communication skills. This article provides strategies to reduce and manage early aggression in the general practice environment. Aggressive behaviour usually occurs when a person feels unfairly treated. Having a systematic approach to the problem can improve safety for both staff and patients. This includes patient centred practice, identifying and managing the early signs of aggression to prevent escalation, having a plan to seek assistance if required, setting limits using a calm respectful manner and reinforcing limits using behaviour contracts when required. The physical layout of the practice and restraint of aggressive people are beyond the scope of this article.

Numerical assessment affects aggression and competitive ability: a team-fighting strategy for the ant Formica xerophila

2006-01-01

The relationship between numerical advantage and competitive ability is a fundamental component in contests between groups of social animals. An individual's ability to correctly assess the numerical state of its group is of vital importance. In addition to numerical dominance, the group's fighting ability also plays an important role in competitive interactions. By staging experimental fights between two Formica ant species, I show that Formica xerophila are able to assess their own group's strength prior to any competitive encounter. Ants that perceive themselves as part of a large group act more aggressively toward a competitor than ants that perceive themselves as isolated individuals. This increase in aggression improves F. xerophila's competitive ability. Furthermore, the number of individuals in a contest was found to affect competitive ability. In contests with equal number of competitors, groups of F. xerophila were more successful than individual F. xerophila. Contrary to previous predictions using Lanchester's laws of fighting, F. xerophila's ability to kill competitors increased nonlinearly with group size. This nonlinearity was due to the collective fighting strategy of an F. xerophila group isolating and engaging a single Formica integroides competitors. PMID:17015327

Methamphetamine use remains a prevalent problem in the United States and is linked to numerous deleterious outcomes, including aggressive behavior, criminal activity, and incarceration. Given these associations, a greater understanding of factors that contribute to aggression among users of methamphetamine is needed, particularly within criminal justice settings, where users of this drug are overrepresented. The present study examined the relationships between posttraumatic stress disorder (PTSD) symptoms and emotion dysregulation and in-prison physical aggression among incarcerated males who identified as methamphetamine users (N = 60). Participants' average age was 34.4 years (SD = 7.9), and they were predominantly European American (n = 48, 80%), had spent an average of 6.53 years incarcerated (SD = 4.64), and perpetrated about 1.54 acts of aggression (SD = 6.74) during the past three months. Bivariate correlations found that greater PTSD symptoms (p < .001), greater impulse control difficulties (p < .001), and limited access to emotion regulation strategies (p < .05) were associated with aggression perpetrated in prison. However, results from multiple regression analyses indicated that only PTSD symptoms (p <.001) and nonacceptance of emotional responses (p < .03) were predictive of aggression. Regression analyses also suggested that impulse control difficulties (p < .001), limited access to emotion regulation strategies (p < .04), and nonacceptance of emotional responses (p < .001) interacted with PTSD symptoms to predict increased aggressive behavior. The first interaction ran counter to study hypotheses: At greater levels of PTSD symptoms, those with greater acceptance of emotional responses reported greater aggression perpetration than those with lesser acceptance of emotional responses. The other two interactions were in line with hypotheses, showing that at greater levels of PTSD symptoms, those with greater impulse control difficulties (or lesser access

Group Music Intervention Reduces Aggression and Improves Self-esteem in Children with Highly Aggressive Behavior: A Pilot Controlled Trial

2010-01-01

We investigated the effects of group music intervention on aggression and self-esteem in children with highly aggressive behavior. Forty-eight children were allocated to either a music intervention group or an untreated control group. The music intervention group received 50 min of music intervention twice weekly for 15 consecutive weeks. The outcome measures were Child Behavior Checklist Aggression Problems Scale (Parents), Child Aggression Assessment Inventory (Teachers) and Rosenberg Self-esteem Scale. After 15 weeks, the music intervention group showed significant reduction of aggression and improvement of self-esteem compared with the control group. All outcome measures were significantly lower in the music intervention group than prior to treatment, while there was no change in the control group. These findings suggest that music can reduce aggressive behavior and improve self-esteem in children with highly aggressive behavior. Music intervention is an easily accessible therapy for children and as such may be an effective intervention for aggressive behavior. Further more, objective and replicable measures are required from a randomized controlled trial with a larger sample size and active comparable control. PMID:18955314

Melatonin, a hormone released preferentially by the pineal gland during the night, affects circadian rhythms and aging processes. As animal studies have shown that melatonin increases resident-intruder aggression, this study aimed to investigate the impact of melatonin treatment on human aggression. In a double-blind, randomized, placebo-controlled between-participant design, 63 healthy male volunteers completed the Taylor Aggression Paradigm (TAP) after oral administration of melatonin or placebo. We found that when given the opportunity to administer high or low punishments to an opponent, participants who ingested melatonin selected the high punishment more often than those who ingested placebo. The increased reactive aggression under melatonin administration remained after controlling for inhibitory ability, trait aggression, trait impulsiveness, circadian preference, perceptual sensibility to noise, and changes in subjective sleepiness and emotional states. This study provides novel and direct evidence for the involvement of melatonin in human social processes.

Although research on the relation between testosterone and aggression in humans is inconclusive, guidelines (including the World Professional Association for Transgender Health Standards of Care, edition 7) have warned for an increase in aggression in transgender men taking testosterone treatment. To investigate the association between levels of testosterone and aggression in treatment-seeking transgender people and explore the role of mental health psychopathology (anxiety and depressive symptoms) and social support in aggression in this population. Every transgender person invited for assessment at a national transgender health clinic in the United Kingdom during a 3-year period (2012-2015) completed self-report measures for interpersonal problems, including levels of aggression (Inventory of Interpersonal Problems [IIP-32]), symptoms of anxiety and depression (Hospital Anxiety and Depression Scale [HADS]), social support (Multidimensional Scale of Perceived Social Support), and experiences of transphobia before and 1 year after the initiation of gender-affirming hormonal therapy. Correlations between prospective scores for the IIP-32 factor "too aggressive" and prospective levels of sex steroids, prospective psychological (HADS), and baseline psychosocial measurements were tested. Prospective scores for the factor "too aggressive" were not correlated to prospective serum testosterone levels. Results of 140 people (56 transgender men, 84 transgender women) were analyzed. A prospective increase in scores for the factor "too aggressive" of the IIP-32 in transgender men 1 year after being treated with testosterone treatment or a decrease of the IIP-32 aggression scores in transgender women 1 year after gender-affirming hormonal therapy was not found. However, a positive correlation was found between increasing HADS anxiety scores and increasing scores for the IIP-32 "too aggressive" score in the entire study population and a positive correlation with lower support

To describe our institutional experience with deep-brain stimulation (DBS) used in the treatment of aggressive and disruptive behavior refractory to conservative treatment. With stereotactic methodology and under general anesthesia, seven patients (from 2002 to 2010) were given DBS in the posterior hypothalamic region, bilaterally, and with the aid of intraoperative microrecording. Six of seven patients presented a clear reduction in the aggression and disruptive bouts, with subsequent simplification of familiar management. DBS of the posterior hypothalamic region could be an effective treatment for patients affected by mental retardation in whom disruptive and drug-refractory aggressive behavior coexists. Although several experimental data are available on this target, further studies are necessary to confirm the long-term efficacy and safety of this procedure. Copyright © 2013.

Ravens reconcile after aggressive conflicts with valuable partners.

PubMed

Fraser, Orlaith N; Bugnyar, Thomas

2011-03-25

Reconciliation, a post-conflict affiliative interaction between former opponents, is an important mechanism for reducing the costs of aggressive conflict in primates and some other mammals as it may repair the opponents' relationship and reduce post-conflict distress. Opponents who share a valuable relationship are expected to be more likely to reconcile as for such partners the benefits of relationship repair should outweigh the risk of renewed aggression. In birds, however, post-conflict behavior has thus far been marked by an apparent absence of reconciliation, suggested to result either from differing avian and mammalian strategies or because birds may not share valuable relationships with partners with whom they engage in aggressive conflict. Here, we demonstrate the occurrence of reconciliation in a group of captive subadult ravens (Corvus corax) and show that it is more likely to occur after conflicts between partners who share a valuable relationship. Furthermore, former opponents were less likely to engage in renewed aggression following reconciliation, suggesting that reconciliation repairs damage caused to their relationship by the preceding conflict. Our findings suggest not only that primate-like valuable relationships exist outside the pair bond in birds, but that such partners may employ the same mechanisms in birds as in primates to ensure that the benefits afforded by their relationships are maintained even when conflicts of interest escalate into aggression. These results provide further support for a convergent evolution of social strategies in avian and mammalian species.

Neuroendocrine aspects of pediatric aggression: Can hormone measures be clinically useful?

Pediatric aggression is common in human societies, mainly presenting as impulsive aggression or predatory aggression. Numerous psychiatric disorders can contain aggression as a symptom, leading to difficulties in diagnosis and treatment. This review focuses on the biological systems that affect pediatric aggression. We review the hypothalamic–pituitary–adrenal (HPA) axis, the hypothalamic–pituitary–gonadal (HPG) axis, and the mechanisms by which these axes influence the body and mind of aggressive children and adolescents. Although this review focuses on the HPA and HPG axes, it is important to note that other biological systems have relationships with these two axes. Based on the results of the studies reviewed, elevated cortisol concentrations were associated with impulsive aggression, whereas, low levels of cortisol were associated with callous-unemotional traits similar to predatory aggression. Higher levels of dehydroepiandrosterone were correlated with higher levels of aggression as were higher levels of testosterone. However, there have been discrepancies in the results between various studies, indicating the need for more research on hormonal levels and pediatric aggression. In the future, hormonal levels may be useful in determining what treatments will work best for certain pediatric patients. PMID:21127686

The prognosis of colorectal cancer in UICC stage IV has been improved in the last decades by improvements in interdisciplinary treatment. Treatment strategies for oligometastasized colorectal cancer are developing more and more into an individualized treatment. An overview of the current literature of modern treatment concepts in oligometastasized colorectal cancer UICC stage IV is given. Surgery still has the supreme mandate in resectable colorectal liver metastases, as neoadjuvant and adjuvant treatment strategies to not provide any benefits for these patients. In marginal or non-resectable stages systemic treatment is superior in these patients depending on the prognostic parameters. Also in curative settings local treatment options should be considered as a reasonable additive tool. An interesting treatment approach for isolated liver metastases and non-resectable colorectal cancer is liver transplantation. Irrespective of new developments in treatment strategies for metastasized colorectal cancer, resection of colorectal liver metastases remains the gold standard whenever possible.

Formal caregivers' experiences of aggressive behaviour in older people living with dementia in nursing homes: A systematic review.

2017-12-01

The purpose of this study was to investigate formal caregivers' experiences of aggressive behaviour in older people living with dementia in nursing homes. Aggressive behaviour symptoms among older people living with dementia are reported to be prevalent. As aggressive behaviour includes both verbal and physical behaviours, such as kicking, hitting and screaming, it causes an increased burden on formal caregivers. Professionals experiencing this aggression perceived it as challenging, causing physical and psychological damage, leading to anger, stress and depression. A systematic review was conducted. A search of published research studies between 2000 and 2015 was conducted using appropriate search terms. Eleven studies were identified and included in this review. The analysis resulted in four categories: formal caregivers' views on triggers of aggression, expressions of aggression, the effect of aggressive behaviours on formal caregivers and formal caregivers' strategies to address aggression. The results show that aggressive behaviour may lead to negative feelings in formal caregivers and nursing home residents. The results of this study suggest that having the ability to identify triggers possibly assists caregivers with addressing aggressive behaviour. Aggressive behaviour might also affect quality of care. Results from this systematic review indicate that caregivers prefer person-centred strategies to handle aggressive behaviour among older people, while the use of pharmaceuticals and coercion strategies is a last resort. © 2017 John Wiley & Sons Ltd.

Although abnormal metabolic regulation is a critical determinant of cancer cell behavior, it is still unclear how an altered balance between ATP production and consumption contributes to malignancy. Here we show that disruption of this energy balance efficiently suppresses aggressive malignant gliomas driven by mammalian target of rapamycin complex 1 (mTORC1) hyperactivation. In a mouse glioma model, mTORC1 hyperactivation induced by conditional Tsc1 deletion increased numbers of glioma-initiating cells (GICs) in vitro and in vivo Metabolic analysis revealed that mTORC1 hyperactivation enhanced mitochondrial biogenesis, as evidenced by elevations in oxygen consumption rate and ATP production. Inhibition of mitochondrial ATP synthetase was more effective in repressing sphere formation by Tsc1-deficient glioma cells than that by Tsc1-competent glioma cells, indicating a crucial function for mitochondrial bioenergetic capacity in GIC expansion. To translate this observation into the development of novel therapeutics targeting malignant gliomas, we screened drug libraries for small molecule compounds showing greater efficacy in inhibiting the proliferation/survival of Tsc1-deficient cells compared with controls. We identified several compounds able to preferentially inhibit mitochondrial activity, dramatically reducing ATP levels and blocking glioma sphere formation. In human patient-derived glioma cells, nigericin, which reportedly suppresses cancer stem cell properties, induced AMPK phosphorylation that was associated with mTORC1 inactivation and induction of autophagy and led to a marked decrease in sphere formation with loss of GIC marker expression. Furthermore, malignant characteristics of human glioma cells were markedly suppressed by nigericin treatment in vivo Thus, targeting mTORC1-driven processes, particularly those involved in maintaining a cancer cell's energy balance, may be an effective therapeutic strategy for glioma patients. © 2016 by The American

Event-related potentials in impulsively aggressive juveniles: a retrospective chart-review study.

The assessment, treatment and management of aggressive youth represent a major clinical challenge facing pediatric mental health professionals today. Although a number of studies have examined physiological differences among aggressive patients vs. controls, the current literature lacks a comprehensive examination of the electroencephalographic activity of impulsively aggressive juveniles. The current study was designed to fill this void in the literature via a retrospective chart review of 80 male and female juveniles undergoing inpatient treatment for pathologically impulsive aggression. Clinical reports for mid- and late-latency event-related potentials (ERPs) were examined to determine their correlations with aggression characteristics, as well as any differential predictive utility of hemispheric differences and auditory vs. visual potentials. Results indicated that decrements of mid-latency potentials and ERPs evoked by auditory stimuli (vs. late-latency components and visual ERPs) were more highly predictive of aggressive behavior. No significant hemispheric differences were noted. Taken together, these results have theoretical significance for the etiology of impulsive aggression, and perhaps also clinical relevance for the treatment of this condition.

The project goal was to compare the effectiveness of strategies to prevent and de-escalate aggressive behaviors among psychiatric patients in acute care settings, including interventions for reducing use of seclusion and restraint. Relevant databases were systematically reviewed for comparative studies of violence prevention and de-escalation strategies involving adult psychiatric patients in acute care settings. Studies (trials and cohort studies) were required to report on aggression or seclusion or restraint outcomes. Both risk of bias, an indicator of quality of individual studies, and strength of evidence (SOE) for each outcome were independently assessed by two study personnel. Seventeen primary studies met inclusion criteria. Evidence was limited for benefits and harms; information about characteristics that might modify the interventions' effectiveness, such as race or ethnicity, was especially limited. All but one study had a medium or high risk of bias and thus presented worrisome limitations. For prevention, risk assessment reduced both aggression and use of seclusion and restraint (low SOE), and multimodal interventions reduced the use of seclusion and restraint (low SOE). SOE for all other interventions, whether aimed at preventing or de-escalating aggression, and for modifying characteristics was insufficient. Available evidence about strategies for preventing and de-escalating aggressive behavior among psychiatric patients is very limited. Two preventive strategies, risk assessment and multimodal interventions consistent with the Six Core Strategies principles, may effectively lower aggressive behavior and use of seclusion and restraint, but more research is needed on how best to prevent and de-escalate aggressive behavior in acute care settings.

Orthodontic Management in Aggressive Periodontitis

PubMed Central

2017-01-01

Aggressive periodontitis is a type of periodontitis with early onset and rapid progression and mostly affecting young adults who occupy a large percentage of orthodontic patients. The role of the orthodontist is important in screening the disease, making a provisional diagnosis, and referring it to a periodontist for immediate treatment. The orthodontist should be aware of the disease not only before starting the appliance therapy, but also during and after the active mechanotherapy. The orthodontic treatment plan, biomechanics, and appliance system may need to be modified to deal with the teeth having reduced periodontal support. With proper force application and oral hygiene maintenance, orthodontic tooth movement is possible without any deleterious effect in the tooth with reduced bone support. With proper motivation and interdisciplinary approach, orthodontic treatment is possible in patients with controlled aggressive periodontitis. PMID:28299350

Hawk-dove games have been extensively used to predict the conditions under which group-living animals should defend their resources against potential usurpers. Typically, game-theoretic models on aggression consider that resource defense may entail energetic and injury costs. However, intruders may also take advantage of owners who are busy fighting to sneak access to unguarded resources, imposing thereby an additional cost on the use of the escalated hawk strategy. In this article we modify the two-strategy hawk-dove game into a three-strategy hawk-dove-sneaker game that incorporates a distraction-sneaking tactic, allowing us to explore its consequences on the expected level of aggression within groups. Our model predicts a lower proportion of hawks and hence lower frequencies of aggressive interactions within groups than do previous two-strategy hawk-dove games. The extent to which distraction sneakers decrease the frequency of aggression within groups, however, depends on whether they search only for opportunities to join resources uncovered by other group members or for both unchallenged resources and opportunities to usurp.

Rates of diabetes and its associated comorbidities have been increasing in the United States, with diabetic foot ulcer treatment representing a large cost to the patient and healthcare system. These ulcers often result in multiple hospital admissions. This study examined readmissions following inpatient care for a diabetic foot ulcer and identified modifiable factors associated with all-cause 30-day readmissions to the inpatient or emergency department (ED) setting. We hypothesized that patients undergoing aggressive treatment would have lower 30-day readmission rates. We identified patient discharge records containing International Classification of Disease ninth revision codes for both diabetes mellitus and distal foot ulcer in the State Inpatient and Emergency Department databases from the Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project in Florida and New York, 2011-2012. All-cause 30-day return to care visits (ED or inpatient) were analyzed. Patient demographics and treatment characteristics were evaluated using univariate and multivariable regression models. The cohort included 25,911 discharges, having a mean age of 63 and an average of 3.8 comorbidities. The overall rate of return to care was 30%, and 21% of subjects underwent a toe or midfoot amputation during their index stay. The most common diagnosis codes upon readmission were diabetes mellitus (19%) and infection (13%). Patients with a toe or midfoot amputation procedure were less likely to be readmitted within 30 days (odds ratio: 0.78; 95% confidence interval: 0.73, 0.84). Presence of comorbidities, black and Hispanic ethnicities, and Medicare and Medicaid payer status were also associated with higher odds of readmission following initial hospitalization (p < 0.05). The study suggests that there are many factors that affect readmission rates for diabetic foot ulcer patients. Understanding patients at high-risk for readmission can improve counseling and

Clozapine is used in the management of treatment-resistant schizophrenia and is effective in reducing aggression; however a subgroup of patients is poorly responsive. For violent patients in this group, there is limited literature on the use of strategies to augment clozapine with other agents. Here we present a case series of 6 schizophrenia patients, within a high-security hospital, who have a history of serious violence and who were treated with clozapine augmented with amisulpride. We reviewed case notes and health records for evidence of violence/aggression and positive factors such as engagement in activities, and Clinical Global Impression (CGI) scores were formulated. We also examined metabolic parameters before and after augmentation. All 6 of the patients showed clinical improvement in symptoms and a reduction in their risk of violence to others. Five patients had a reduction in number of violent/aggressive incidents, and all patients showed improvement in engagement in occupational, vocational, and/or psychological work. Metabolic parameters were largely unchanged except for 1 patient whose Body Mass Index (BMI) increased. Five patients reported side effects as unchanged or improved. These schizophrenia patients with a history of violence showed clinical improvement and reduced aggression and violence with amisulpride augmentation of clozapine. To our knowledge, this is the first report of an antiaggressive benefit of this combination in forensic psychiatric patients. Further studies are warranted to establish the efficacy and anti-aggressive effects of amisulpride augmentation of clozapine.

Aquino, Karl; Thau, Stefan

2009-01-01

This article reviews research on workplace victimization, which we define as acts of aggression perpetrated by one or more members of an organization that cause psychological, emotional, or physical harm to their intended target. We compare several types of victimizing behaviors that have been introduced into the organizational psychology literature to illustrate differences and similarities among them. We then review studies looking at who is likely to become a victim of aggression. Predictors include personality, demographic, behavioral, structural, and organizational variables. We also review research on coping strategies for victimization, which include problem-focused and emotion-focused strategies. We conclude with a summary of challenges for victimization research. These include addressing the proliferation of constructs and terms into the literature, attempting to clarify inconclusive findings, and using theory to guide the selection of study variables.

The role of monoamine oxidase A in aggression: current translational developments and future challenges

2016-01-01

Drawing upon the recent resurgence of biological criminology, several studies have highlighted a critical role for genetic factors in the ontogeny of antisocial and violent conduct. In particular, converging lines of evidence have documented that these maladaptive manifestations of aggression are influenced by monoamine oxidase A (MAOA), the enzyme that catalyzes the degradation of brain serotonin, norepinephrine and dopamine. The interest on the link between MAOA and aggression was originally sparked by Han Brunner’s discovery of a syndrome characterized by marked antisocial behaviors in male carriers of a nonsense mutation of this gene. Subsequent studies showed that MAOA allelic variants associated with low enzyme activity moderate the impact of early-life maltreatment on aggression propensity. In spite of overwhelming evidence pointing to the relationship between MAOA and aggression, the neurobiological substrates of this link remain surprisingly elusive; very little is also known about the interventions that may reduce the severity of pathological aggression in genetically predisposed subjects. Animal models offer a unique experimental tool to investigate these issues; in particular, several lines of transgenic mice harboring total or partial loss-of-function Maoa mutations have been shown to recapitulate numerous psychological and neurofunctional endophenotypes observed in humans. This review summarizes the current knowledge on the link between MAOA and aggression; in particular, we will emphasize how an integrated translational strategy coordinating clinical and preclinical research may prove critical to elucidate important aspects of the pathophysiology of aggression, and identify potential targets for its diagnosis, prevention and treatment.

Emotional Labour of Caregivers Confronted With Aggressive Brain-injured Patients.

PubMed

Huet, Magali; Dany, Lionel; Apostolidis, Thémistoklis

2018-06-01

Aggressive behaviours are common with people who have suffered brain injuries and induce difficult emotions among certified nursing assistants and medical-psychological assistants who take care of them. These caregivers carry out emotional labour whose content and strategies are little known. The study explores the emotional labour of certified nursing assistants and medical-psychological assistants faced with the aggressive behaviours of brain-injured patients. Semi-structured interviews were conducted with 37 caregivers. Interviews were analysed via a thematic content analysis. The analysis shows that the emotional labour of caregivers varies in accordance with the state of "consciousness" or "non-consciousness" that they attribute to the brain-injured patient with regard to this aggressive behaviour. This is a deep acting strategy. Moreover, caregivers shut off their emotions in order not to transmit them to the patient. This surface acting has the first objective for the caregiver of maintaining control of the situation and a second objective of protecting the patient emotionally and therefore of being perceived as a "good" caregiver. Emotional labour also meets a need to preserve the professional self-image and professional status negatively affected in the interaction with the aggressive brain-injured patient. Our study specifies the different strategies of the emotional labour of caregivers and their circumstances of use when they are confronted with aggressive behaviour by brain-injured patients. Targeted support for this emotional labour, such as training and practical analysis, is essential for the development of care practices promoting a caring relationship. Copyright © 2017 Elsevier Inc.

Neurobiological factors in aggressive behavior.

PubMed

Garza-Treviño, E S

1994-07-01

The author's aim was to review literature in the neurosciences and psychiatric clinical research reports about biological factors in aggression and the pathophysiological mechanisms that accompany aggression in neuropsychiatric syndromes. Studies were located through computer searches of relevant experimental reports and review articles mainly from the last 25 years. Several studies using neuroimaging and neurophysiological and neuropathological research techniques have identified lesions in the limbic structures, temporal lobes, and frontal lobes of the brain in abnormally aggressive individuals. Several reports have associated deficiency or dysregulation of serotonin with homicidal, suicidal, and impulsive behavior. However, few studies have focused on polypeptides or second messenger systems, although abnormalities in these systems have been reported in patients with neuropsychiatric syndromes who have shown aggressive behavior. Even fewer studies focus on the correlation of brain structures and metabolic markers. The understanding of aggressive behavior in psychiatric patients is fragmented. Some explanations are speculative and extrapolated to clinical psychiatric syndromes from experimental data on the neurophysiology of cats, rats, and other mammals. Identification of biochemical markers that can be used in predicting patients' response to pharmacological interventions may be the next step in developing more rational treatment of violent patients.

2005-01-01

In this study of patients with borderline personality disorder (BPD) or antisocial personality disorder (ASPD) hospitalized because of aggressive behavior, auditory and visual P300 evoked potentials were obtained prior to treatment with valproate. Eight ASPD patients (8 males, 0 females) and 11 BPD patients (2 males, 9 females) showed improvement, while in 7 patients with ASPD (7 males, 0 females) and 10 patients with BPD (2 males, 8 females), aggression was not improved. Differences in auditory and visual P300 latencies and amplitudes were not significant for either diagnosis, or for both diagnoses combined. These findings suggest that auditory or visual P300 evoked potentials may not be useful for predicting response of aggressive behavior to valproate treatment in patients with BPD or ASPD.

Parents’ Aggressive Influences and Children's Aggressive Problem Solutions with Peers

This study examined children's aggressive and assertive solutions to hypothetical peer scenarios in relation to parents’ responses to similar hypothetical social scenarios and parents’ actual marital aggression. The study included 118 9−10 year old children, and their mothers and fathers. Children's aggressive solutions correlated with same-sex parents’ actual marital aggression. For children with mothers who exhibit low actual marital aggression, mothers’ aggressive solutions to hypothetical situations corresponded with children's tendencies to propose aggressive but not assertive solutions. In a 3-way interaction, fathers’ aggressive solutions to peer scenarios and marital aggression, combined, exacerbated girls’ aggressive problem solving, but had the opposite effect for boys. Discussion addresses the complexity, particularly with respect to parent and child gender combinations, in understanding parents’ aggressive influences on children's peer relationships.

Nursing and aggression in the workplace: a systematic review.

PubMed

Edward, Karen-leigh; Ousey, Karen; Warelow, Philip; Lui, Steve

Personal experiences of aggression or violence in the workplace lead to serious consequences for nurses, their patients, patient care and the organisation as a whole. While there is a plethora of research on this topic, no review is available that identifies types of aggression encountered, individuals perceived to be most at risk and coping strategies for victims. The aim of this systematic review was to examine occupational anxiety related to actual aggression in the workplace for nurses. Databases (MEDLINE, CINAHL and PsycINFO) were searched, resulting in 1543 titles and abstracts. After removal of duplicates and non-relevant titles, 137 papers were read in full. Physical aggression was found to be most frequent in mental health, nursing homes and emergency departments while verbal aggression was more commonly experienced by general nurses. Nurses exposed to verbal or physical abuse often experienced a negative psychological impact post incident.

Aggression management training for nurses is an important part of a comprehensive strategy to reduce patient and visitor aggression in healthcare. Although training is commonplace, few scientific studies examine its benefits. To explore and describe, from a nurse's perspective, the learning gained from attending aggression management training. This was a descriptive qualitative interview study. We conducted semi-structured individual interviews with seven nurses before (September/October 2012) and after they attended aggression management training (January/February 2013). Interview transcripts were content-analysed qualitatively. The study plan was reviewed by the responsible ethics committees. Participants gave written informed consent. Aggression management training did not change nurses' attitude. Coping emotionally with the management of patient and visitor aggression remained a challenge. Nurses' theoretical knowledge increased, but they did not necessarily acquire new strategies for managing patient/visitor aggression. Instead, the course refreshed or activated existing knowledge of prevention, intervention and de-escalation strategies. The training increased nurses' environmental and situational awareness for early signs of patient and visitor. They also acquired some strategies for emotional self-management. Nurses became more confident in dealing with (potentially) aggressive situations. While the training influenced nurses' individual clinical practice, learning was rarely shared within teams. Aggression management training increases skills, knowledge and confidence in dealing with patient or visitor aggression, but the emotional management remains a challenge. Future research should investigate how aggression management training courses can strengthen nurses' ability to emotionally cope with patient and visitor aggression. More knowledge is needed on how the theoretical and practical knowledge gained from the training may be disseminated more effectively

Behavioural indicators of motives for barroom aggression: implications for preventing bar violence.

2011-09-01

To develop new strategies for preventing violence in high-risk licensed premises, we identify behavioural indicators of apparent motives for aggression in these settings and outline the implications of different motivations for prevention. The four types of motives for aggressive or coercive acts defined by the theory of coercive actions framed the research: gaining compliance, expressing grievances/restoring justice, attaining a favourable social identity and pursuing fun/excitement. Incidents of aggression from the Safer Bars evaluation research were analysed to identify behavioural indicators of each motivation. Compliance-motivated aggression typically takes the form of unwanted social overtures, third party intervention to stop conflicts or staff rule enforcement. Prevention strategies include keeping the aggressor's focus on compliance to avoid provoking grievance and identity motives that are likely to escalate aggression. Grievance motives are typically elicited by perceived wrongdoing and therefore prevention should focus on eliminating sources of grievances and adopting policies/practices to resolve grievances peacefully. Social identity motives are endemic to many drinking establishments especially among male patrons and staff. Prevention involves reducing identity cues in the environment, hiring staff who do not have identity concerns, and training staff to avoid provoking identity concerns. Aggression motivated by fun/excitement often involves low-level aggression where escalation can be prevented by avoiding grievances and attacks on identity. Knowledge of behavioural indicators of motives can be used to enhance staff hiring and training practices, reduce environmental triggers for aggression, and develop policies to reduce motivation for aggression. © 2011 Australasian Professional Society on Alcohol and other Drugs.

Purpose To investigate whether parents’ previous physical aggression (PPA) exhibited during early adolescence is associated with adolescents’ subsequent parent-directed aggression even beyond parents’ concurrent physical aggression (CPA); to investigate whether adolescents’ emotion dysregulation and attitudes condoning child-to-parent aggression moderate associations. Methods Adolescents (N = 93) and their parents participated in a prospective, longitudinal study. Adolescents and parents reported at waves 1–3 on four types of parents’ PPA (mother-to-adolescent, father-to-adolescent, mother-to-father, father-to-mother). Wave 3 assessments also included adolescents’ emotion dysregulation, attitudes condoning aggression, and externalizing behaviors. At waves 4 and 5, adolescents and parents reported on adolescents’ parent-directed physical aggression, property damage, and verbal aggression, and on parents’ CPA Results Parents’ PPA emerged as a significant indicator of adolescents’ parent-directed physical aggression (odds ratio [OR]: 1.25, 95% confidence interval [CI]: 1.0–1.55; p = .047), property damage (OR: 1.29, 95% CI: 1.1–1.5, p = .002), and verbal aggression (OR: 1.35, 95% CI: 1.15–1.6, p < .001) even controlling for adolescents’ sex, externalizing behaviors, and family income. When controlling for parents’ CPA, previous mother-to-adolescent aggression still predicted adolescents’ parent-directed physical aggression (OR: 5.56, 95% CI: 1.82–17.0, p = .003), and father-to-mother aggression predicted adolescents’ parent-directed verbal aggression (OR: 1.86, 95% CI: 1.0–3.3, p = .036). Emotion dysregulation and attitudes condoning aggression did not produce direct or moderated effects. Conclusions Adolescents’ parent-directed aggression deserves greater attention in discourse about lasting, adverse effects of even minor forms of parents’ physical aggression. Future research should investigate parent-directed aggression as

Whereas interspecific associations receive considerable attention in evolutionary, behavioural and ecological literature, the proximate bases for these associations are usually unknown. This in particular applies to associations between vertebrates with invertebrates. The West-African savanna frog Phrynomantis microps lives in the underground nest of ponerine ants (Paltothyreus tarsatus). The ants usually react highly aggressively when disturbed by fiercely stinging, but the frog is not attacked and lives unharmed among the ants. Herein we examined the proximate mechanisms for this unusual association. Experiments with termites and mealworms covered with the skin secretion of the frog revealed that specific chemical compounds seem to prevent the ants from stinging. By HPLC-fractionation of an aqueous solution of the frogs' skin secretion, two peptides of 1,029 and 1,143 Da were isolated and found to inhibit the aggressive behaviour of the ants. By de novo sequencing using tandem mass spectrometry, the amino acid sequence of both peptides consisting of a chain of 9 and 11 residues, respectively, was elucidated. Both peptides were synthesized and tested, and exhibited the same inhibitory properties as the original frog secretions. These novel peptides most likely act as an appeasement allomone and may serve as models for taming insect aggression.

Antiepileptic drugs (AEDs) have many benefits but also many side effects, including aggression, agitation, and irritability, in some patients with epilepsy. This article offers a comprehensive summary of current understanding of aggressive behaviors in patients with epilepsy, including an evidence-based review of aggression during AED treatment. Aggression is seen in a minority of people with epilepsy. It is rarely seizure related but is interictal, sometimes occurring as part of complex psychiatric and behavioral comorbidities, and it is sometimes associated with AED treatment. We review the common neurotransmitter systems and brain regions implicated in both epilepsy and aggression, including the GABA, glutamate, serotonin, dopamine, and noradrenaline systems and the hippocampus, amygdala, prefrontal cortex, anterior cingulate cortex, and temporal lobes. Few controlled clinical studies have used behavioral measures to specifically examine aggression with AEDs, and most evidence comes from adverse event reporting from clinical and observational studies. A systematic approach was used to identify relevant publications, and we present a comprehensive, evidence-based summary of available data surrounding aggression-related behaviors with each of the currently available AEDs in both adults and in children/adolescents with epilepsy. A psychiatric history and history of a propensity toward aggression/anger should routinely be sought from patients, family members, and carers; its presence does not preclude the use of any specific AEDs, but those most likely to be implicated in these behaviors should be used with caution in such cases.

Aggressive/attacking and helpful/emphatic/prosocial behaviors are extremely important in human relationships. Both high levels of aggression and deficits of prosociality play important role in the development and conservation of mental disorders. We review the measurement options and clinical importance of aggressive and prosocial behavior. The typical developmental pathways and the genetic and environmental background of these behaviors are presented. The clinical tools used in the measurement of aggression and prosociality are summarized in the present paper, with specific attention on questionnaires applied in Hungarian practice. The connections between diagnostic categories (conduct disorder, oppositional-defiant disorder, attention deficit and hyperactive disorder, autism spectrum disorders) and the two behaviors are evaluated. In the end, we present those additional research projects that explore the cognitive-emotional background of aggressive or prosocial behavior with clinical relevance either in the diagnosis or in the treatment of child psychiatric diseases.

While much attention has been devoted toward treatment paradigms for idiopathic axillo-subclavian vein thrombosis (ASVT), little has focused on long-term durability of aggressive treatment and its associated functional outcomes. The purpose of this study was to review our own surgical therapeutic algorithm and its associated durability and functional outcomes. All patients treated with combined endovascular and open surgery at Dartmouth-Hitchcock Medical Center for ASVT from 1988 to 2008 were identified. Patient demographics, comorbidities, and operative techniques were recorded. Patency, freedom from reintervention, and functional outcomes were documented. Follow-up via telephone and clinic visit allowed quantitative comparison of functional status, pre- and postoperatively. Thirty-six patients were treated for ASVT throughout the study interval. Seven patients (19.4%) were lost to follow-up. Most patients were male (66%; N = 24); mean age was 32 years. Catheter-directed thrombolysis was utilized in the majority of patients (83.3%; N = 30) with an average time from symptom onset to lysis of 12 days. Surgical decompression was undertaken in all patients via transaxillary (52%; N = 19), supraclavicular (31%; N = 11), or infraclavicular approaches (17%; N = 6). Eleven stents were placed in 11 patients (30.5%) for residual stenotic disease. Mean follow-up was 65 months, with 1- and 5-year overall patency at 100% and 94%, respectively. Freedom from reintervention was 100% and 74.4% at 1 and 5 years, respectively. Seven patients (19.4%) required postoperative reintervention with four receiving additional lytic therapy, two requiring a stent, and one venoplasty. At presentation, 65.5% (N = 19) of patients were unable to work or perform routine activities. After treatment, 86% (N = 25) returned to their employment and have experienced sustained symptomatic and functional improvement. Patients with symptomatic idiopathic axillo-subclavian vein thrombosis can expect durable

Only a small number of patients with aggressive B-cell lymphoma take part in clinical trials, and elderly patients in particular are under-represented. Therefore, we studied data of the population-based nationwide Netherlands Cancer Registry to determine trends in incidence, treatment and survival in an unselected patient population. We included all patients aged 15 years and older with newly diagnosed diffuse large B-cell lymphoma or Burkitt lymphoma in the period 1989–2010 and mantle cell lymphoma in the period 2001–2010, with follow up until February 2013. We examined incidence, first-line treatment and survival. We calculated annual percentage of change in incidence and carried out relative survival analyses. Incidence remained stable for diffuse large B-cell lymphoma (n=23,527), while for mantle cell lymphoma (n=1,634) and Burkitt lymphoma (n=724) incidence increased for men and remained stable for women. No increase in survival for patients with aggressive B-cell lymphoma was observed during the period 1989–1993 and the period 1994–1998 [5-year relative survival 42% (95%CI: 39%–45%) and 41% (38%–44%), respectively], but increased to 46% (43%–48%) in the period 1999–2004 and to 58% (56%–61%) in the period 2005–2010. The increase in survival was most prominent in patients under 65 years of age, while there was a smaller increase in patients over 75 years of age. However, when untreated patients were excluded, patients over 75 years of age had a similar increase in survival to younger patients. In the Netherlands, survival for patients with aggressive B-cell lymphoma increased over time, particularly in younger patients, but also in elderly patients when treatment had been initiated. The improvement in survival coincided with the introduction of rituximab therapy and stem cell transplantation into clinical practice. PMID:25512643

Aggression on haemodialysis units is a growing problem internationally that has received little research attention to date. Aggressive behaviour by patients or their relatives can compromise the safety and well-being of staff and other patients sharing a haemodialysis session. The objectives of the study were twofold: First, to identify the prevalance and nature of aggression on haemodialysis units; and second, to investigate factors that contribute to aggressive behaviour on haemodialysis units. A cross-sectional, sequential mixed method research design was adopted, with two research methods utilised. Incidents of aggressive behaviour were recorded over a 12-month period, using a renal version of the Staff Observation Aggression Scale. Six months after the incident data collection had commenced, semi-structured qualitative interviews were conducted with 29 multidisciplinary members of staff. Over 12 months, 74 aggressive incidents were recorded. The majority of incidents involved verbal aggression, and the perpetrators were a minority of patients, relatives and staff. Two patients were responsible for 38% of all incidents; both patients had mental health problems. Distinct temporal patterns to the aggressive behaviour were observed according to the day of the week and time of day. This study demonstrates that aggression is a significant problem on haemodialysis units, with verbal aggression most prevalent. The temporal patterns to aggression observed are related to the uniqueness of the haemodialysis setting, with a distinctly different treatment environment compared with other healthcare settings. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

There is a need for instruments that can be used in correctional settings to measure changes in aggressive behaviors over a limited time period. This study aimed to validate an instrument (the Prison Adjusted Measure of Aggression, PAMA) that assesses specifically the past month's aggressive behaviors and is adapted for use in correctional facilities. The psychometric properties of the self-rated and interview versions of the PAMA were explored and compared to those of two well-established measures of aggression: The Staff Observation Aggression Scale (SOAS); and the self-rate Aggression Questionnaire-Revised Swedish Version (AQ-RSV). The study group comprised 93 male and 59 female inmates, who were followed for two months. During the study, the prevalence of aggressive acts was observed and reported by SOAS. On two occasions, at monthly intervals, subjects reported their own aggressive behaviors using AQ-RSV and the self-report version of the PAMA; also, a psychologist conducted interviews according to PAMA. This study's main finding was that the self-rated version of PAMA is a valid measure of different types and dimensions of aggression (physical and verbal aggression, hostility) and has acceptable psychometric properties. Therefore, PAMA could potentially be of value for use in correctional services evaluating aggression managing treatment interventions. Copyright © 2018 The Authors. Published by Elsevier B.V.

Poor sleep as a potential causal factor in aggression and violence.

PubMed

Kamphuis, Jeanine; Meerlo, Peter; Koolhaas, Jaap M; Lancel, Marike

2012-04-01

Clinical observations suggest that sleep problems may be a causal factor in the development of reactive aggression and violence. In this review we give an overview of existing literature on the relation between poor sleep and aggression, irritability, and hostility. Correlational studies are supporting such a relationship. Although limited in number, some studies suggest that treatment of sleep disturbances reduces aggressiveness and problematic behavior. In line with this is the finding that sleep deprivation actually increases aggressive behavior in animals and angriness, short-temperedness, and the outward expression of aggressive impulses in humans. In most people poor sleep will not evoke actual physical aggression, but certain individuals, such as forensic psychiatric patients, may be particularly vulnerable to the emotional dysregulating effects of sleep disturbances. The relation between sleep problems and aggression may be mediated by the negative effect of sleep loss on prefrontal cortical functioning. This most likely contributes to loss of control over emotions, including loss of the regulation of aggressive impulses to context-appropriate behavior. Other potential contributing mechanisms connecting sleep problems to aggression and violence are most likely found within the central serotonergic and the hypothalamic-pituitary-adrenal-axis. Individual variation within these neurobiological systems may be responsible for amplified aggressive responses induced by sleep loss in certain individuals. It is of great importance to identify the individuals at risk, since recognition and adequate treatment of their sleep problems may reduce aggressive and violent incidents.

Lennox-Gastaut syndrome is an intractable epileptic encephalopathy marked by frequent drop seizures. Most patients develop moderate intellectual disability and behavioral problems, including hyperactivity, aggressiveness, insecurity, and autistic features. Treatment with benzodiazepines, including clobazam, may increase aggression/behavioral problems in patients with Lennox-Gastaut syndrome. Post hoc analyses of data from the OV-1012 trial assessed the potential for behavioral effects with clobazam treatment in pediatric (2 to 18 years) patients with Lennox-Gastaut syndrome. OV-1012 was a phase 3, randomized, double-blind, parallel-group trial comprising a 4-week baseline period, 3-week titration period, and a 12-week maintenance period. Data from 194 patients were analyzed for a history of aggression/behavioral problems, occurrence of aggression-related adverse events, and by assessment of potential drug-related effects on four behavior domains of the Child Behavior Checklist. Twenty-nine aggression-related adverse events were reported for 27 (13.9%) patients. Similar percentages of clobazam-treated patients with and without a history of aggressive behavior experienced an aggression-related adverse event (16.7% versus 15.5%, respectively). In the medium- and high-dosage clobazam groups, onset of aggression-related adverse effects occurred within the 3-week titration period with 63.2% resolving by the end of the study. Aggression-related adverse event onset and resolution were similar for the low-dosage clobazam and placebo groups. Analysis of baseline to postbaseline T scores for the behavior domains of the Child Behavior Checklist indicated no significant differences between clobazam and placebo. Post hoc analyses indicate that the overall rate of aggression with clobazam treatment was low and dosage dependent. Clobazam treatment was effective in reducing drop seizures regardless of aggression experience. Copyright © 2015 Elsevier Inc. All rights reserved.

The present study examined sibling influence over reactive and proactive aggression in a sample of 452 same-sex twins (113 male dyads, 113 female dyads). Between and within siblings influence processes were examined as a function of relative levels of parental coercion and hostility to test the hypothesis that aggression contagion between twins occurs only among dyads who experience parental coerciveness. Teacher reports of reactive and proactive aggression were collected for each twin in kindergarten (M = 6.04 years; SD = 0.27) and in first grade (M = 7.08 years; SD = 0.27). Families were divided into relatively low, average, and relatively high parental coercion-hostility groups on the basis of maternal reports collected when the children were 5 years old. In families with relatively high levels of parental coercion-hostility, there was evidence of between-sibling influence, such that one twin’s reactive aggression at age 6 predicted increases in the other twin’s reactive aggression from ages 6 to 7, and one twin’s proactive aggression at age 6 predicted increases in the other twin’s proactive aggression from ages 6 to 7. There was also evidence of within-sibling influence such that a child’s level of reactive aggression at age 6 predicted increases in the same child’s proactive aggression at age 7, regardless of parental coercion-hostility. The findings provide new information about the etiology of reactive and proactive aggression and individual differences in their developmental interplay. PMID:25683448

Aggression in psychiatry wards: a systematic review.

Although fairly frequent in psychiatric in-patient, episodes of aggression/violence are mainly limited to verbal aggression, but the level of general health is significantly lower in nurses who report 'frequent' exposure to violent incidents, and there is disagreement between patients and staff concerning predictors of these episodes. We searched the Pubmed, Embase and PsychInfo databases for English, Italian, French or German language papers published between 1 January 1990 and 31 March 2010 using the key words "aggress*" (aggression or aggressive) "violen*" (violence or violent) and "in-patient" or "psychiatric wards", and the inclusion criterion of an adult population (excluding all studies of selected samples such as a specific psychiatric diagnosis other than psychosis, adolescents or the elderly, men/women only, personality disorders and mental retardation). The variables that were most frequently associated with aggression or violence in the 66 identified studies of unselected psychiatric populations were the existence of previous episodes, the presence of impulsiveness/hostility, a longer period of hospitalisation, non-voluntary admission, and aggressor and victim of the same gender; weaker evidence indicated alcohol/drug misuse, a diagnosis of psychosis, a younger age and the risk of suicide. Alcohol/drug misuse, hostility, paranoid thoughts and acute psychosis were the factors most frequently involved in 12 studies of psychotic patients. Harmony among staff (a good working climate) seems to be more useful in preventing aggression than some of the other strategies used in psychiatric wards, such as the presence of male nurses.

To evaluate the cost-effectiveness of all 4 interventions in the Treatment of Early Aggressive Rheumatoid Arthritis (TEAR) clinical trial: immediate triple (IT), immediate etanercept (IE), step-up triple (ST), and step-up etanercept (SE). Step-up interventions started with methotrexate and added either etanercept or sulfasalazine plus hydroxychloroquine to patients with persistent disease activity. We built a Markov cohort model that uses individual-level data from the TEAR trial, published literature, and supplemental clinical data. Costs were in US dollars, benefits in quality-adjusted life years (QALYs), perspective was societal, and the time horizon was 5 years. The immediate strategies were more efficacious than step-up strategies. SE and IE were more costly than ST and IT, primarily due to treatment cost differences. In addition, IT was the least expensive and most effective strategy when the time horizon was 1 and 2 years. When the time horizon was 5 years, IE was marginally more effective than IT (3.483 versus 3.476 QALYs), but IE was substantially more expensive than IT ($148,800 versus $52,600), producing an incremental cost-effectiveness ratio of $12.5 million per QALY. These results were robust to both one-way deterministic and joint probabilistic sensitivity analyses. IT was highly cost-effective in the majority of scenarios. Although IE was more effective in 5 years, a substantial reduction in the cost of biologic agents was required in order for IE to become cost-effective in early aggressive RA under willingness-to-pay thresholds that most health care settings may find acceptable. © 2016, American College of Rheumatology.

2006-01-01

The concept of aggression is important to nursing because further knowledge of aggression can help generate a better theoretical model to drive more effective intervention and prevention approaches. This paper outlines a conceptual analysis of aggression. First, the different forms of aggression are reviewed, including the clinical classification and the stimulus-based classification. Then the manifestations and measurement of aggression are described. Finally, the causes and consequences of aggression are outlined. It is argued that a better understanding of aggression and the causal factors underlying it are essential for learning how to prevent negative aggression in the future. PMID:15371137

2015-08-01

Both intimate partner violence (IPV) and community violence are prevalent globally, and each is associated with serious health consequences. However, little is known about their potential links or the possible benefits of coordinated prevention strategies. Using aggregated data on community violence from the São Paulo State Security Department (INFOCRIM) merged with WHO multi-country study on women's health and domestic violence data, random intercept models were created to assess the effect of crime on women's probability of experiencing IPV. The association between IPV and male aggression (measured by women's reports of their partner's fights with other men) was examined using logistic regression models. We found little variation in the likelihood of male IPV perpetration related to neighborhood crime level but did find an increased likelihood of IPV experiences among women whose partners were involved in male-to-male violence. Emerging evidence on violence prevention has suggested some promising avenues for primary prevention that address common risk factors for both perpetration of IPV and male interpersonal violence. Strategies such as early identification and effective treatment of emotional disorders, alcohol abuse prevention and treatment, complex community-based interventions to change gender social norms and social marketing campaigns designed to modify social and cultural norms that support violence may work to prevent simultaneously male-on-male aggression and IPV. Future evaluations of these prevention strategies should simultaneously assess the impact of interventions on IPV and male interpersonal aggression.

[Sexual aggression against girls and adult women--causes and consequences].

PubMed

Bitzer, J

2005-04-01

The causes of sexual aggression are multiple. Bioevolutionary rooted behavioral dispositions (sexual aggressiveness of men as a reproductive strategy) are enforced by specific male dominated structures of society and socially determined stereotypes of female roles which deter women from self determination of their sexuality; these macrosocial factors combine with individual conditions of socialization, in which violence plays an important role. With respect to the consequences of sexual aggression primary victimization (the trauma itself with physical and psychological harm) can be distinguished from secondary victimization (devaluation and mistrust in the social environment). The degree of negative health outcomes depends on risk factors like previous abuse, severity of the violent act, and lack of social support. Prevention must aim at changes of societal conditions that enhance sexual aggression and the establishment of programs for men and women at risk in which techniques of control of sexual aggression, attenuation and inhibition can be learnt.

Sense of control and adolescents' aggression: The role of aggressive cues.

Guo, Xucheng; Egan, Vincent; Zhang, Jianxin

The misperception of aggressive cues is considered a risk factor for inducing adolescent aggression. Poor coping with life stress is also considered a major influence on aggression. The current study examined the relationship between subjective sense of control and adolescent aggression, considering influences upon the perception of these aggressive cues. In Study 1, 60 participants took part in a 2 (sense of control: high sense of control vs. low sense of control) × 2 (aggressive cue: aggressive vs. neutral) between-subjects contextual experiment. The result found that a lower sense of control led to an increase in adolescents' aggression; only in the low-sense-of-control condition did exposure to aggressive cues boost aggression. In Study 2, the catalytic effect of aggressive cues was further explored by an experiment in which 40 adolescents were randomly assigned to a low- or high-sense-of-control condition to test the importance of aggressive cues. The results suggest that adolescents in the low-sense-of-control condition show a higher salience for aggressive cues. © 2016 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

Aggressive blood pressure treatment of hypertensive intracerebral hemorrhage may lead to global cerebral hypoperfusion: Case report and imaging perspective.

Hypoperfusion injury related to blood pressure decrease in acute hypertensive intracerebral hemorrhage continues to be a controversial topic. Aggressive treatment is provided with the intent to stop the ongoing bleeding. However, there may be additional factors, including autoregulation and increased intracranial pressure, that may limit this approach. We present here a case of acute hypertensive intracerebral hemorrhage, in which aggressive blood pressure management to levels within the normal range led to global cerebral ischemia within multiple border zones. Global cerebral ischemia may be of concern in the management of hypertensive hemorrhage in the presence of premorbid poorly controlled blood pressure and increased intracranial pressure.

Both attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are frequently accompanied by serious aggression that requires psychiatric treatment. However, little is known about the experiences psychiatrists have had using pharmacotherapy to treat aggression in patients who have both ASD and ADHD (ASD/ADHD). The purpose of this study was to examine the experiences of Japanese child and adolescent psychiatrists in prescribing medication for aggression in patients with ASD/ADHD. A prospective questionnaire was mailed to 2001 psychiatrists affiliated with the Japanese Society for Child and Adolescent Psychiatry. Multivariate logistic regression analysis was used to identify factors predicting the outcome of pharmacotherapeutic treatment of aggression in pediatric and adolescent patients with ASD/ADHD. Of 2001 psychiatrists, 571 (28.5%) completed the full questionnaire (final sample). Of these, 488 (85.4%) prescribed psychotropic medication in treating pediatric and adolescent patients with ASD/ADHD, 299 (61.3%) of them doing so to treat aggression. Prescribers' duration of practice (odds ratio, 1.055; P = 0.038) and patient symptoms of residual impulsivity (odds ratio, 2.479; P = 0.039) increased the odds of prescribing psychotropic medications to treat aggression in these patients. The respondents reported a similar effect for patients with ADHD/ASD compared with those with ADHD only in treating aggression. Japanese psychiatrists tended to prescribe psychotropic medication for aggression in pediatric and adolescent patients with ASD/ADHD. Future studies examining aggression in pediatric and adolescent patients with ASD/ADHD should aim to accumulate evidence for the use of psychotropic medications, which could help clinicians make better decisions. © 2017 The Authors.

2004-12-01

In order to evaluate the special injury pattern of aggressive inline skating, a field study was conducted in a local, non-commercial skate park equipped with all the typical features like ramps, halfpipes, gully areas. 66 unselected aggressive inline skaters were randomly enrolled and interviewed concerning their skating habits and their skating injury history. Average age was 15 (10 to 41) years, skating was performed since 2.1 (0.1 to 6) years, as aggressive skating since 1.3 (0.1 to 4) years. Medical treatment in a doctor's practice or in a hospital had been necessary in 66 cases, averaging 1.4 times per skater and year, averaging one injury per 586 hours of aggressive skating. The injury pattern reflected the regions typically injured in fitness skating, too, with a higher percentage of injuries concerning knee, tibia and ankle region. The use of protective devices varied from 41 % (wrist guards) to 94 % (knee pads), with an average of 69 %. Only 32 % of skaters wore all protective devices. As the personal thrill is an important motivation for aggressive skating, safer skating campaigns are quite unlikely to decrease the risk of injury in aggressive skaters.

A Teacher-Focused Approach to Prevent and Reduce Students' Aggressive Behavior

Orpinas, Pamela; Home, Arthur M.

2009-01-01

The purpose of this article is to describe the GREAT (Guiding Responsibility and Expectations for Adolescents for Today and Tomorrow) Teacher Program, a prevention program for middle school teachers to deter students' aggressive behavior. It was developed on the basis of an ecologic understanding of aggression and on specific constructs of Social Cognitive Theory. The goals of the program were (1) to increase teacher awareness of different types of aggression, risk factors, role of the classroom teacher, and influence of the school climate on the child's behavior; (2) to develop strategies that will prevent aggression; (3) to improve teacher management skills to reduce power struggles and aggression; and (4) to enhance skills to assist students who are the targets of aggression. To accomplish these goals, teachers participated in a 12-hour workshop and 10 support group sessions. Training, manuals, and supervision were provided to maintain program integrity and to assure the quality of implementation. PMID:14732185

Caudate dysfunction is implicated in schizophrenia. However, little is known about the relationship between aggression and caudate volumes. Forty-nine patients received magnetic resonance imaging scanning in a double-blind treatment study in which aggression was measured. Caudate volumes were computed using a semiautomated method. The authors measured aggression with the Overt Aggression Scale and the Positive and Negative Syndrome Scale. Larger caudate volumes were associated with greater levels of aggression. The relationship between aggression and caudate volumes may be related to the iatrogenic effects of long-term treatment with typical anti-psychotic agents or to a direct effect of schizophrenic processes on the caudate.

Depression is one of the most common chronic mental disorders, which is a leading cause of morbidity and mortality in patients. Depression often leads to offensive and defensive behaviours but the underlying mechanisms are not known. We propose that the aggressive behaviours in depression can be modelled in animal experiments. In this study, we successfully established a mouse model of depression using the chronic unpredictable mild stress (CUMS) paradigm and detected aggressive and social dominance behaviours in rodents by resident/intruder test and social dominance tube test (SDTT), respectively. The CUMS-exposed mice showed increased defensive, offensive and aggressive behaviours in the resident-intruder test. In the SDTT, these mice showed enhanced social dominance. These alterations were associated with reduced MAP-2 expression in the hippocampus while no difference in β-tubulin expression was detected. In addition, the treatment of anti-depressant fluoxetine reversed the aggressive behaviours without reducing the social dominance behaviour induced by CUMS. However, fluoxetine did effectively reverted the changes in MAP-2 expression in the hippocampus. In addition, the nonspecific tricyclic antipsychotic drug, clozapine, reversed all symptoms of CUMS-exposed mice including aggressive tendencies, impulsive violence, social dominance behaviour and MAP-2 expression in the hippocampus. The results suggests that social maladjustment such as competition and social dominance are likely related to the dopaminergic system rather than the serotonergic system and the hippocampal dendritic structure protein MAP-2. Thus, dominance can be separated from aggression. This study shows that aggression/hostility and social hierarchy/dominance are increased in the CUMS-exposed mice and thus provide an excellent model for further study in the diagnosis and the treatment of depression-associated aggression.

Alcohol-related aggression-social and neurobiological factors.

2013-10-01

Alcohol-related aggression and violence are a widespread cause of personal suffering with high socioeconomic costs. In 2011, nearly one in three violent acts in Germany was committed under the influence of alcohol (31.8%). The link between alcohol consumption and aggression is promoted by various interacting factors. In this review, based on a selective search for pertinent literature in PubMed, we analyze and summarize information from original articles, reviews, and book chapters about alcohol and aggression and discuss the neurobiological basis of aggressive behavior. Aggression is promoted both by the cognitive deficits arising in connection with acute or chronic alcohol use and by prior experience of violence in particular situations where alcohol was drunk. Only a minority of persons who drink alcohol become aggressive. On the other hand, alcohol abuse and dependence together constitute the second most commonly diagnosed cause of suicide (15-43%). Current research indicates that the individual tendency toward alcohol-induced aggression depends not just on neurobiological factors, but also on personal expectations of the effects of alcohol, on prior experience of violent conflicts, and on the environmental conditions of early childhood, especially social exclusion and discrimination. Gene-environment interactions affecting the serotonergic and other neurotransmitter systems play an important role. Potential (but not yet adequately validated) therapeutic approaches involve reinforcing cognitive processes or pharmacologically modulating serotonergic neurotransmission (and other target processes). Alcohol-related aggression has manifold social and neurobiological causes. Specific treatments must be tested in controlled trials.

Signaling aggression.

From psychological and sociological standpoints, aggression is regarded as intentional behavior aimed at inflicting pain and manifested by hostility and attacking behaviors. In contrast, biologists define aggression as behavior associated with attack or escalation toward attack, omitting any stipulation about intentions and goals. Certain animal signals are strongly associated with escalation toward attack and have the same function as physical attack in intimidating opponents and winning contests, and ethologists therefore consider them an integral part of aggressive behavior. Aggressive signals have been molded by evolution to make them ever more effective in mediating interactions between the contestants. Early theoretical analyses of aggressive signaling suggested that signals could never be honest about fighting ability or aggressive intentions because weak individuals would exaggerate such signals whenever they were effective in influencing the behavior of opponents. More recent game theory models, however, demonstrate that given the right costs and constraints, aggressive signals are both reliable about strength and intentions and effective in influencing contest outcomes. Here, we review the role of signaling in lieu of physical violence, considering threat displays from an ethological perspective as an adaptive outcome of evolutionary selection pressures. Fighting prowess is conveyed by performance signals whose production is constrained by physical ability and thus limited to just some individuals, whereas aggressive intent is encoded in strategic signals that all signalers are able to produce. We illustrate recent advances in the study of aggressive signaling with case studies of charismatic taxa that employ a range of sensory modalities, viz. visual and chemical signaling in cephalopod behavior, and indicators of aggressive intent in the territorial calls of songbirds.

Neuroimaging correlates of aggression in schizophrenia: an update.

PubMed

Hoptman, Matthew J; Antonius, Daniel

2011-03-01

Aggression in schizophrenia is associated with poor treatment outcomes, hospital admissions, and stigmatization of patients. As such it represents an important public health issue. This article reviews recent neuroimaging studies of aggression in schizophrenia, focusing on PET/single photon emission computed tomography and MRI methods. The neuroimaging literature on aggression in schizophrenia is in a period of development. This is attributable in part to the heterogeneous nature and basis of that aggression. Radiological methods have consistently shown reduced activity in frontal and temporal regions. MRI brain volumetric studies have been less consistent, with some studies finding increased volumes of inferior frontal structures, and others finding reduced volumes in aggressive individuals with schizophrenia. Functional MRI studies have also had inconsistent results, with most finding reduced activity in inferior frontal and temporal regions, but some also finding increased activity in other regions. Some studies have made a distinction between types of aggression in schizophrenia in the context of antisocial traits, and this appears to be useful in understanding the neuroimaging literature. Frontal and temporal abnormalities appear to be a consistent feature of aggression in schizophrenia, but their precise nature likely differs because of the heterogeneous nature of that behavior.

Atypical antipsychotic drugs have been used off-label in clinical practice for treatment of serious dementia-associated agitation and aggression. Following reports of cerebrovascular adverse events associated with the use of atypical antipsychotic in elderly patients with dementia, the FDA issued black box warnings for several atypical antipsychotics, titled “Cerebrovascular Adverse Events, including Stroke, in Elderly Patients with Dementia.” Subsequently, the FDA initiated a meta-analysis of safety data from 17 registration trials across six antipsychotic drugs (five atypical antipsychotics and haloperidol). In 2005, the Agency issued a black box warning regarding increased risk of mortality associated with the use of atypical antipsychotic drugs in this patient population. Geriatric mental health experts participating in a 2006 consensus conference reviewed evidence on the safety and efficacy of antipsychotics, as well as nonpharmacologic approaches, in treating dementia-related symptoms of agitation and aggression. They concluded that, while problems in clinical trials design may have been one of the contributors to the failure to find a signal of drug efficacy, the findings related to drug safety should be taken seriously by clinicians in assessing the potential risks and benefits of treatment in a frail population, and in advising families about treatment. Information provided to patients and family members should be documented in the patient’s chart. Drugs should be used only when non-pharmacologic approaches have failed to adequately control behavioral disruption. Participants also agreed that that there is a need for an FDA-approved medication for the treatment of severe, persistent or recurrent dementia-related symptoms of agitation and aggression (even in the absence of psychosis), that are unresponsive to nonpharmacologic intervention. The authors have outlined methodological enhancements to better evaluate treatment approaches in future

In the different psychiatric disorders the aggression often leads to uncontrolled events, taking aspects of impulsiveness and irrationality. Our research proposes the assessment of socio-demographic and clinical characteristics of patients with a psychiatric disorder, who presented an aggressive event. The observational study was conducted on a sample of 50 patients (34 men and 16 women), hospitalized following the manifestation of an aggressive event. For each patient was provided an assessment of socio-demographic and clinical variables and a psychometric investigation through: the OAS, for the analysis of aggressive episodes; the BDHI, for the hostile behavior and attitudes; the BIS-11, for the impulsiveness and the BPRS for the psychopathological aspects. Among the socio-demographic features investigated, the highest correlation with aggressive behavior was related to the concomitant substance abuse, type of admission to psychiatric hospital and the male gender. The OAS has shown a greater propensity to directed-aggression in males with schizophrenia, and self-directed in females with major depression. The BPRS has shown a positive correlation between hetero-directed aggressive behavior and positive symptomatology, and between the self-directed and depression, risk of suicide, feelings of guilt and somatic concerns. The BDHI has indicated greater suspicion in women's group. The hypothesis that aggression is otherwise related to specific socio-demographic and clinical characteristics was confirmed by our study. The data suggest that early identification and assessment of potential risk factors involved in the genesis of aggressive episodes would allow the clinician to implement a better strategy for prevention and intervention.

A multilevel analysis of aggressive behaviors among nursing home residents.

Individual and organizational characteristics associated with aggressive behavior among nursing home residents were examined among a sample of 5,494 residents from 23 facilities using the Minimum Data Set 2.0 and the Organizational Social Context scale. On admission, some individual level variables (age, sex, depression, activities of daily life [ADL] impairments, and cognitive impairments) and no organizational level variables were associated with aggressive behaviors. Over time, aggressive behaviors were linked with some individual characteristics (age, sex, and ADL impairments) and several organizational level variables (stressful climates, less rigid cultures, more resistant cultures, geographic location, facility size and staffing patterns). Findings suggest multi-faceted change strategies are needed.

This study assessed girls’ and boys’ dominance-related behaviors (aggressive, commanding, submissive, and neutral behaviors) as they naturally occurred during interactions with male and female peers and evaluated the possibility that such behaviors elicit aggression from peers. Using a focal observational procedure, young girls’ and boys’ (N = 170; 54% boys) naturally occurring dominance-related behaviors and male and female peers’ aggressive responses to those behaviors were recorded multiple times each week across the academic year. Findings suggested that same-gender aggression occurred at similar rates as other-gender aggression once tendencies toward gender segregated play were controlled. Additionally, there were both gender-based similarities and differences in children’s use of dominance-related behaviors in peer interactions and as antecedents for peers’ aggression. The findings have implications for the literatures on aggression and gendered peer interactions. PMID:22369337

Background Aggressive situations occurring within mental health services can harm service users, staff, and the therapeutic environment. There is a consensus that the aggression phenomenon is multidimensional, but the picture is still unclear concerning the complex interplay of causal variables and their respective impact. To date, only a small number of empirical studies include users’ views of relevant factors. The main objective of this review is to identify and synthesize evidence relating to service users’ experiences and views of aggressive situations in mental health settings. Methods We included qualitative studies of any design reporting on service users’ own experiences of conditions contributing to aggressive situations in mental health care and their views on preventative strategies. Eligible articles were identified through an electronic database search (PsycINFO, PubMed, Ovid Nursing Database, Embase, and CINAHL), hand search, and cross-referencing. Extracted data were combined and interpreted using aspects of thematic synthesis. Results We reviewed 5,566 records and included 13 studies (ten qualitative and three mixed methods). Service users recognized that both their own mental state and negative aspects of the treatment environment affected the development of aggressive situations. Themes were derived from experiential knowledge and included calls to be involved in questions regarding how to define aggression and relevant triggers, and how to prevent aggressive encounters effectively. The findings suggest that incidents are triggered when users experience staff behavior as custodial rather than caring and when they feel ignored. Conclusion The findings highlight the importance of staffs’ knowledge and skills in communication for developing relationships based on sensitivity, respect, and collaboration with service users in order to prevent aggressive situations.

As an environmental poison, arsenic is responsible for many cancer deaths. Paradoxically, arsenic trioxide (ATO) presents also a powerful therapy used to treat refractory acute promyelocytic leukemia (APL) and is intensively investigated for treatment of other cancer types. Noteworthy, cancer therapy is frequently hampered by drug resistance, which is also often associated with enhancement of tumor aggressiveness. In this study, we analyzed ATO-selected cancer cells (A2780ATO) for the mechanisms underlying their enhanced tumorigenicity and aggressiveness. These cells were characterized by enhanced proliferation and spheroid growth as well as increased tumorigenicity of xenografts in SCID mice. Noteworthy, subsequent studies revealed that overexpression of Met receptor was the underlying oncogenic driver of these effects, as A2780ATO cells were characterized by collateral sensitivity against Met inhibitors. This finding was also confirmed by array comparative genomic hybridization (array CGH) and whole genome gene expression arrays, which revealed that Met overexpression by chronic ATO exposure was based on the transcriptional regulation via activation of AP-1. Finally, it was shown that treatment with the Met inhibitor crizotinib was also effective against A2780ATO cell xenografts in vivo, indicating that targeting of Met presents a promising strategy for the treatment of Met-overexpressing tumors after either arsenic exposure or failure to ATO treatment.

2018-06-01

The present study uses data from 35 third through fifth-grade urban classrooms and 531 students to examine the extent to which student-level social and emotional skills (e.g., low hostile attribution bias and low aggressive interpersonal negotiation strategies) and emotionally supportive learning environments predict aggressive behavior over the course of a school year. Results of multiple regression analyses indicated that across teacher-reported measures of aggressive behavior, more classroom emotional support over the course of the school year predicted less aggressive behavior in spring, particularly for children whose hostile attribution bias decreased over the course of the year. According to a child-reported measure of aggressive behavior, declines in aggressive interpersonal negotiation strategies over the course of the year also predicted less aggressive behavior in spring. Moreover, these results operated similarly across all children. Implications for SEL programs are discussed. Published by Elsevier Ltd.

Behavioral and Pharmacogenetics of Aggressive Behavior

Serotonin (5-HT) has long been considered as a key transmitter in the neurocircuitry controlling aggression. Impaired regulation of each subtype of 5-HT receptor, 5-HT transporter, synthetic and metabolic enzymes has been linked particularly to impulsive aggression. The current summary focuses mostly on recent findings from pharmacological and genetic studies. The pharmacological treatments and genetic manipulations or polymorphisms of a specific target (e.g., 5-HT1A receptor) can often result in inconsistent results on aggression, due to “phasic” effects of pharmacological agents vs “trait”-like effects of genetic manipulations. Also, the local administration of a drug using the intracranial microinjection technique has shown that activation of specific subtypes of 5-HT receptors (5-HT1A and 5-HT1B) in mesocorticolimbic areas can reduce species-typical and other aggressive behaviors, but the same receptors in the medial prefrontal cortex or septal area promote escalated forms of aggression. Thus, there are receptor populations in specific brain regions that preferentially modulate specific types of aggression. Genetic studies have shown important gene × environment interactions; it is likely that the polymorphisms in the genes of 5-HT transporters (e.g., MAO A) or rate-limiting synthetic and metabolic enzymes of 5-HT determine the vulnerability to adverse environmental factors that escalate aggression. We also discuss the interaction between the 5-HT system and other systems. Modulation of 5-HT neurons in the dorsal raphe nucleus by GABA, glutamate, and CRF profoundly regulate aggressive behaviors. Also, interactions of the 5-HT system with other neuropeptides (arginine vasopressin, oxytocin, neuropeptide Y, opioid) have emerged as important neurobiological determinants of aggression. Studies of aggression in genetically modified mice identified several molecules that affect the 5-HT system directly (e.g., Tph2, 5-HT1B, 5-HT transporter, Pet1, MAOA) or

Agreeableness and alcohol-related aggression: the mediating effect of trait aggressivity.

This study investigated the mediating effect of trait aggressivity on the relation between agreeableness and alcohol-related aggression in a laboratory setting. Participants were 116 healthy male social drinkers between 21 and 30 years of age. Agreeableness and trait aggressivity were measured using the Big Five Inventory and the Buss-Perry Aggression Questionnaire, respectively. Following the consumption of an alcohol or no-alcohol control beverage, participants completed a modified version of the Taylor Aggression Paradigm, in which electric shocks were received from and administered to a fictitious opponent during a competitive task. Aggression was operationalized as the proportion of the most extreme shocks delivered to the fictitious opponent under conditions of low and high provocation. Results indicated that lower levels of agreeableness were associated with higher levels of trait aggressivity. In turn, higher levels of trait aggressivity predicted extreme aggression in intoxicated, but not sober, participants under low, but not high, provocation. Findings highlight the importance of examining determinants of intoxicated aggression within a broader theoretical framework of personality.

To analyze the spectrum of aggressive posterior retinopathy of prematurity and outcome after laser treatment. This is a retrospective review of 81 eyes of 44 consecutive infants diagnosed to have aggressive posterior retinopathy of prematurity and treated between September 2005 and March 2007 from a large tertiary care center in North India. Qualitative variables were tested for statistical significance using the chi-square test and independent samples with the student's t-test. Mean birth weight and gestational age were 1,259.66 +/- 310.51 g (range, 660-2,000 g) and 29.75 +/- 2.35 weeks (range, 26-36 weeks), respectively. Twenty-one infants (47.72%) had a birth weight > 1,250 g. Thirty-three (40.74%) eyes had Zone 1, and 48 (59.26%) had posterior Zone 2 disease. All eyes underwent confluent laser photocoagulation at a mean postconceptional age of 34.58 +/- 2.19 weeks (range, 31-40.5 weeks). Mean follow-up was 12.8 months (range, 6-24 months). At the last follow-up visit, 55 (71.4%) of 77 eyes had a favorable outcome. Eighteen eyes (23.4%) had a localized (1-3 clock hours) partial peripheral tractional detachment (Stage 4a), which remained stable at last follow-up. Two eyes (2.6%) developed falciform fold involving the macular area, and 2 (2.6%) developed Stage 5 retinopathy of prematurity. Aggressive posterior retinopathy of prematurity is encountered not only in low birth weight infants, but also in heavier and more mature Asian Indian infants. Early, aggressive confluent laser photocoagulation is necessary to maximize outcomes in these eyes.

2013-01-01

This longitudinal study examined normative beliefs about aggression (e.g., face-to-face, cyber) in relation to the engagement in cyber aggression 6 months later among 126 (69 women) young adults. Participants completed electronically administered measures assessing their normative beliefs, face-to-face and cyber aggression at Time 1, and cyber aggression 6 months later (Time 2). We found that men reported more cyber relational and verbal aggression when compared to women. After controlling for each other, Time 1 face-to-face relational aggression was positively related to Time 2 cyber relational aggression, whereas Time 1 face-to-face verbal aggression was positively related to Time 2 cyber verbal aggression. Normative beliefs regarding cyber aggression was positively related to both forms of cyber aggression 6 months later, after controlling for normative beliefs about face-to-face aggression. Furthermore, a significant two-way interaction between Time 1 cyber relational aggression and normative beliefs about cyber relational aggression was found. Follow-up analysis showed that Time 1 cyber relational aggression was more strongly related to Time 2 cyber relational aggression when young adults held higher normative beliefs about cyber relational aggression. A similar two-way interaction was found for cyber verbal aggression such that the association between Time 1 and Time 2 cyber verbal aggression was stronger at higher levels of normative beliefs about cyber verbal aggression. Results are discussed in terms of the social cognitive and behavioral mechanisms associated with the engagement of cyber aggression. © 2013 Wiley Periodicals, Inc.

Aggressive treatment of early rheumatoid arthritis: recognizing the window of opportunity and treating to target goals.

PubMed

Resman-Targoff, Beth H; Cicero, Marco P

2010-11-01

Evidence supports the use of aggressive therapy for patients with early rheumatoid arthritis (RA). Clinical outcomes in patients with early RA can improve with a treat-to-target approach that sets the goal at disease remission. The current selection of antirheumatic therapies, including conventional and biologic disease-modifying antirheumatic drugs (DMARDs), has made disease remission a realistic target for patients with early RA. The challenge is selecting the optimal antirheumatic drug or combination of drugs for initial and subsequent therapy to balance the clinical benefits, risks, and economic considerations. In some cases, the use of biologic agents as part of the treatment regimen has shown superior results compared with conventional DMARDs alone in halting the progression of disease, especially in reducing radiographic damage. However, the use of biologic agents as initial therapy is challenged by cost-effectiveness analyses, which favor the use of conventional DMARDs. The use of biologic agents may be justified in certain patients with poor prognostic factors or those who experience an inadequate response to conventional DMARDs as a means to slow or halt disease progression and its associated disability. In these cases, the higher cost of treatment with biologic agents may be offset by decreased societal costs, such as lost work productivity, and increased health-related quality of life. Further research is needed to understand optimal strategies for balancing costs, benefits, and risks of antirheumatic drugs. Some key questions are (1) when biologic agents are appropriate for initial therapy, and (2) when to conclude that response to conventional DMARDs is inadequate and biologic agents should be initiated.

The authors aimed to explore the relation between nicotine dependence and the severity of aggression among Turkish male alcohol-dependent inpatients who smoked cigarettes, as well as the effect of aggression in these groups. Participants were 126 male alcohol-dependent inpatients who were given the Structured Clinical Interview for DSM-IV, Substance Use Disorder Module (A. Corapcioglu, O. Aydemir, & M. Yildiz, 1999; M. B. First, R. L. Spitzer, & J. B. W. Williams, 1997), the Fagerstrom Test for Nicotine Dependence (K. O. Fagerstrom, 1978), and the Overt Aggression Scale (OAS; S. C. Yudofsky, J. M. Silver, W. Jackson, J. Endicott, & D. Williams, 1986). The authors found differences between male alcohol-dependent inpatients with nicotine dependence (n = 94) and those with nondependence (n = 32) in OAS subtypes. The authors' findings showed that smoking cigarettes-an addiction frequently observed with alcoholism-was positively correlated with aggressive behaviors. The authors suggest that smoking cigarettes may cause aggression or aggression may cause smoking. Observing and evaluating how aggression and smoking cigarettes are associated with alcohol dependence may help relapse prevention and improve effectiveness of treatment interventions in alcoholism.

Coupling Aggressive Mass Removal with Microbial Reductive Dechlorination for Remediation of DNAPL Source Zones: A Review and Assessment

PubMed Central

2005-01-01

The infiltration of dense non-aqueous-phase liquids (DNAPLs) into the saturated subsurface typically produces a highly contaminated zone that serves as a long-term source of dissolved-phase groundwater contamination. Applications of aggressive physical–chemical technologies to such source zones may remove > 90% of the contaminant mass under favorable conditions. The remaining contaminant mass, however, can create a rebounding of aqueous-phase concentrations within the treated zone. Stimulation of microbial reductive dechlorination within the source zone after aggressive mass removal has recently been proposed as a promising staged-treatment remediation technology for transforming the remaining contaminant mass. This article reviews available laboratory and field evidence that supports the development of a treatment strategy that combines aggressive source-zone removal technologies with subsequent promotion of sustained microbial reductive dechlorination. Physical–chemical source-zone treatment technologies compatible with posttreatment stimulation of microbial activity are identified, and studies examining the requirements and controls (i.e., limits) of reductive dechlorination of chlorinated ethenes are investigated. Illustrative calculations are presented to explore the potential effects of source-zone management alternatives. Results suggest that, for the favorable conditions assumed in these calculations (i.e., statistical homogeneity of aquifer properties, known source-zone DNAPL distribution, and successful bioenhancement in the source zone), source longevity may be reduced by as much as an order of magnitude when physical–chemical source-zone treatment is coupled with reductive dechlorination.

Muscarine- and carbachol-induced aggressions: fear and irritable kinds of aggressions.

PubMed

Beleslin, D B; Samardzić, R

1977-12-28

In unaneasthetized and unrestrained cats, muscarine and carbachol were injected into the cerebral ventricles. The kind of aggressive behaviour depended on the cholinomimetic drug and was classified as fear and an irritable kind of aggression. Muscarine induced the fear kind of aggression. The aggressive behaviour was usually preceded by attempts to escape and the attack was relevant to the situation. For the attack the presence of some threatening agent was needed. The aggression was accompanied by intense motor but less autonomic activation. On the other hand, carbachol induced an irritable kind of aggression and had the following characteristics: for the attack the presence of some threatening agent was not needed; the attack was not relevant to the situation; the aggression was not preceded by attempts to escape; and the aggressive behaviour was accompanied by intense motor and autonomic activation. It is concluded that cholinoceptive mechanisms are involved in the control of aggressive behaviour.

Implicit cognitive aggression among young male prisoners: Association with dispositional and current aggression.

PubMed

Ireland, Jane L; Adams, Christine

2015-01-01

The current study explores associations between implicit and explicit aggression in young adult male prisoners, seeking to apply the Reflection-Impulsive Model and indicate parity with elements of the General Aggression Model and social cognition. Implicit cognitive aggressive processing is not an area that has been examined among prisoners. Two hundred and sixty two prisoners completed an implicit cognitive aggression measure (Puzzle Test) and explicit aggression measures, covering current behaviour (DIPC-R) and aggression disposition (AQ). It was predicted that dispositional aggression would be predicted by implicit cognitive aggression, and that implicit cognitive aggression would predict current engagement in aggressive behaviour. It was also predicted that more impulsive implicit cognitive processing would associate with aggressive behaviour whereas cognitively effortful implicit cognitive processing would not. Implicit aggressive cognitive processing was associated with increased dispositional aggression but not current reports of aggressive behaviour. Impulsive implicit cognitive processing of an aggressive nature predicted increased dispositional aggression whereas more cognitively effortful implicit cognitive aggression did not. The article concludes by outlining the importance of accounting for implicit cognitive processing among prisoners and the need to separate such processing into facets (i.e. impulsive vs. cognitively effortful). Implications for future research and practice in this novel area of study are indicated. Copyright © 2015 Elsevier Ltd. All rights reserved.

This study investigated concurrent links between adolescent romantic couples' reports of aggression (relational and physical) and relationship functioning (e.g., attachment security, conflict prevalence, coping strategies, jealousy, and affiliative and romantic relationship quality) using a pattern-oriented approach. The sample included 194 romantic partner dyads (Mage=16.99 years for females and Mage=18.41 years for males). A hierarchical cluster analysis identified five distinct subgroups of dyads based on male and female reports of relational and physical aggression, ranging from nonaggressive couples (42%), to those characterized by aggressive females (18%), aggressive males (14%), physically aggressive females (20%), and mutually aggressive females and males (6%). Clusters in which one partner was perceived as either relationally or physically aggressive were characterized by higher rates of conflict, less adaptive coping, and more jealousy (particularly in males). The mutually aggressive couples showed the least adaptive relationship functioning, with high rates of conflict, a deficit in reflection and emotion regulation in conflict situations, and a lack of affiliative relationship qualities. The discussion focuses on the formative character of aggression in these early romantic relations, the aggravating impact of mutual aggression on relationship functioning, and the gender-specific functions of aggression in relationships characterized by unilateral aggression.

Aggressive behavior and violence in patients, residents or clients are growing challenges in nursing. Aggressive behavior can have both, physical and psychological consequences for nurses and can lead to a reduced performance at work, demotivation, sickness absence and the premature exit from the nursing profession. To develop purposive strategies and to deal with aggressive behavior and health promotion programs, it is crucial to know more about the prevalence of aggressive behavior from patients and the effect on the work ability of nurses in different types of institutions. Data of 1735 German nurses was derived from the European NEXT-Study. Description and analysis of variance for each working area (hospital ward, Intensive Care Unit, psychiatric ward, nursing home and home care) were conducted. The work ability was measured with the Work Ability Index (WAI). The aggressive behavior was measured by one item developed by the NEXT Study Group. Linear regression models were applied to analyze the effect of aggressive behavior on the work ability of nurses in a comparison of the five different working areas. A total of 84.9 percent of the nurses were "sometimes" or "often/always" confronted with aggressive behavior from patients. In the comparison of the five working areas, nurses were exposed to different levels of aggressive behavior, while differences in the work ability of nurses were also observed. It was found that aggressive behavior from patients was associated with reduced work ability in nurses working in hospital wards, nursing homes and home care, but not nurses working in ICUs and psychiatric wards. The findings indicate that many nurses in Germany are exposed to aggressive behavior from patients, which has negative effect on the nurses' work ability. However, it is assumed that strategies to deal with aggressive behavior could play a buffer role between aggressive behavior and work ability of nurses, highlighting one possibility of intervention in

OBJECTIVES The objective of this study was to examine factors that are associated with aggression that is responsive versus refractory to individualized optimization of stimulant monotherapy among children with attention-deficit/hyperactivity disorder (ADHD). METHODS Children who were aged 6 to 13 years and had ADHD, either oppositional defiant disorder or conduct disorder, significant aggressive behavior, and a history of insufficient response to stimulants completed an open stimulant monotherapy optimization protocol. Stimulant titration with weekly assessments of behavior and tolerability identified an optimal regimen for each child. Families also received behavioral therapy. Parents completed the Retrospective-Modified Overt Aggression Scale (R-MOAS) at each visit. Children were classified as having stimulant-refractory aggression on the basis of R-MOAS ratings and clinician judgment. Differences that pertained to treatment, demographic, and psychopathology between groups with stimulant monotherapy–responsive and –refractory aggression were evaluated. RESULTS Aggression among 32 (49.3%) of 65 children was reduced sufficiently after stimulant dosage adjustment and behavioral therapy to preclude adjunctive medication. Those who responded to stimulant monotherapy were more likely to benefit from the protocol’s methylphenidate preparation (once-daily, triphasic release), showed a trend for lower average dosages, and received fewer behavioral therapy sessions than did children with stimulant-refractory aggression. Boys, especially those with higher ratings of baseline aggression and of depressive and manic symptoms, more often exhibited stimulant-refractory aggression. CONCLUSIONS Among children whose aggressive behavior develops in the context of ADHD and of oppositional defiant disorder or conduct disorder, and who had insufficient response to previous stimulant treatment in routine clinical care, systematic, well-monitored titration of stimulant monotherapy

Negative affect and parental aggression in child physical abuse.

Parental negative affect is a risk factor for child physical abuse. As negative affect contributes to aggression, and because physical abuse involves an aggressive act directed at the child, we examined the relationship between negative affect and parent-to-child aggression (PTCA) in parents reported to Child Protective Services for physical abuse. Baseline assessment data were retrospectively examined on 49 participants in a treatment study for child physical abuse. The negative affects studied were depression, anxiety, and hostility on the Beck Depression Inventory and the Brief Symptom Inventory. PTCA was assessed using the physical aggression subscales (Minor and Severe Physical Violence) of the Conflict Tactics Scale. The contribution of these negative affects to PTCA was examined after controlling individually for the effects of parental attributions and contextual variables widely regarded as etiological factors in child physical abuse. Contributions of negative affect to PTCA after individually controlling for other predictors were found for Minor Physical Violence but not Severe Physical Violence. Findings were strongest with depression on the Beck Depression Inventory and to a lesser extent with hostility on the Brief Symptom Inventory. Finding that negative affect contributed to PTCA in this sample suggests that it may be important to study the effects of emotion-focused treatments in physically abusive parents. These findings also suggest that PTCA may have qualities of impulsive aggression, a form of aggression that is conceptualized as driven by negative affect, occurs in response to aversive events, and is not planned.

2014-01-01

Canine aggression is one of the most frequent problems in veterinary behavioral medicine, which in severe cases may result in relinquishment or euthanasia. As it is important to reveal underlying factors of aggression for both treatment and prevention, we recently developed a questionnaire on aggression and temperamental traits and found that “reactivity to stimuli” was associated with aggression toward owners, children, strangers, and other dogs of the Shiba Inu breed. In order to examine whether these associations were consistent in other breeds, we asked the owners of insured dogs of Anicom Insurance Inc. to complete our questionnaire. The top 17 contracted breeds were included. The questionnaire consisted of dogs' general information, four items related to aggression toward owners, children, strangers, and other dogs, and 20 other behavioral items. Aggression-related and behavioral items were rated on a five-point frequency scale. Valid responses (n = 5610) from owners of dogs aged 1 through 10 years were collected. Factor analyses on 18 behavioral items (response rate over 95%) extracted five largely consistent factors in 14 breeds: “sociability with humans,” “fear of sounds,” “chase proneness,” “reactivity to stimuli,” and “avoidance of aversive events.” By stepwise multiple regression analyses, using the Schwartz's Bayesian information criterion (BIC) method with aggression points as objective variables and general information and temperamental factor points as explanatory variables, “reactivity to stimuli,” i.e., physical reactivity to sudden movement or sound at home, was shown to be significantly associated with owner-directed aggression in 13 breeds, child-directed aggression in eight breeds, stranger-directed aggression in nine breeds, and dog-directed aggression in five breeds. These results suggest that “reactivity to stimuli” is simultaneously involved in several types of aggression. Therefore, it would be worth

Biomarkers to Distinguish Aggressive Cancers from Non-aggressive or Non-progressing Cancer — EDRN Public Portal

Cancer.gov

Distinguishing aggressive cancers from non-aggressive or non-progressing cancers is an issue of both clinical and public health importance particularly for those cancers with an available screening test. With respect to breast cancer, mammographic screening has been shown in randomized trials to reduce breast cancer mortality, but given the limitations of its sensitivity and specificity some breast cancers are missed by screening. These so called interval detected breast cancers diagnosed between regular screenings are known to have a more aggressive clinical profile. In addition, of those cancers detected by mammography some are indolent while others are more likely to recur despite treatment. The pilot study proposed herein is highly responsive to the EDRN supplement titled “Biomarkers to Distinguish Aggressive Cancers from Nonaggressive or Non-progressing Cancers” in that it addresses both of the research objectives related to these issues outlined in the notice for this supplement: Aim 1: To identify biomarkers in tumor tissue related to risk of interval detected vs. mammography screen detected breast cancer focusing on early stage invasive disease. We will compare gene expression profiles using the whole genome-cDNA-mediated Annealing, Selection, extension and Ligation (DASL) assay of 50 screen detected cancers to those of 50 interval detected cancers. Through this approach we will advance our understanding of the molecular characteristics of interval vs. screen detected breast cancers and discover novel biomarkers that distinguish between them. Aim 2: To identify biomarkers in tumor tissue related to risk of cancer recurrence among patients with screen detected early stage invasive breast cancer. Using the DASL assay we will compare gene expression profiles from screen detected early stage breast cancer that either recurred within five years or never recurred within five years. These two groups of patients will be matched on multiple factors including

Background We hypothesized intrauterine growth restricted offspring (IUGR) demonstrate higher rates of aggression and higher dominance ranks than control (CTR) offspring with normal weight at term; if aggressive behavior is advantageous during resource scarcity, developmental programming may lead to an association between aggression and IUGR. Methods We studied 22 group-housed baboons (ages 3-5 years). CTR (male n=8, female n=5) mothers ate ad libitum. IUGR (male n=4, female n=5) mothers were fed 70% feed eaten by CTR mothers during pregnancy and lactation. Results IUGR showed higher rates of aggressive displays (p<0.01) and friendly displays (p<0.02). Dominance ranks and physical aggression rates did not differ between groups. Conclusions High rates of IUGR aggressive display might reflect developmental programming of behavioral phenotypes enhancing fitness. Friendly displays may reflect reconciliation. Potential mechanisms include neurodevelopment and learning. Exploration of IUGR as a risk factor for behavioral patterns is important for developing diagnostic and therapeutic strategies.

The purpose of this study was to examine personal and socioenvironmental factors of players' likelihood to aggress. Participants were youth soccer players (N = 258) and their coaches (N = 23) from high school and club teams. Players completed the Judgments About Moral Behavior in Youth Sports Questionnaire (JAMBYSQ; Stephens, Bredemeier, & Shields, 1997), which assessed athletes' stage of moral development, team norm for aggression, and self-described likelihood to aggress against an opponent. Coaches were administered the Coaching Efficacy Scale (CES; Feltz, Chase, Moritz, & Sullivan, 1999). Using multilevel modeling, results demonstrated that the team norm for aggression at the athlete and team level were significant predictors of athletes' self likelihood to aggress scores. Further, coaches' game strategy efficacy emerged as a positive predictor of their players' self-described likelihood to aggress. The findings contribute to previous research examining the socioenvironmental predictors of athletic aggression in youth sport by demonstrating the importance of coaching efficacy beliefs.

Family Predictors of Continuity and Change in Social and Physical Aggression from Ages 9 – 18

This research examined developmental trajectories for social and physical aggression for a sample followed from age 9–18, and investigated possible family predictors of following different trajectory groups. Participants were 158 girls and 138 boys, their teachers, and their parents (21% African American, 5.3% Asian, 51.6% Caucasian, and 21% Hispanic). Teachers rated children’s social and physical aggression yearly in grades 3–12. Participants’ parent (83% mothers) reported on family income, conflict strategies, and maternal authoritarian and permissive parenting styles. The results suggested that both social and physical aggression decline slightly from middle childhood through late adolescence. Using a dual trajectory model, group based mixture modeling revealed three trajectory groups for both social and physical aggression: low-, medium-, and high-desisting for social aggression, and stably-low, stably-medium, and high-desisting for physical aggression. Membership in higher trajectory groups was predicted by being from a single-parent family, and having a parent high on permissiveness. Being male was related to both elevated physical aggression trajectories and the medium-desisting social aggression trajectory. Negative interparental conflict strategies did not predict social or physical aggression trajectories when permissive parenting was included in the model. Permissive parenting in middle childhood predicted following higher social aggression trajectories across many years, which suggests that parents setting fewer limits on children’s behaviors may have lasting consequences for their peer relations. Future research should examine transactional relations between parenting styles and practices and aggression to understand the mechanisms that may contribute to changes in involvement in social and physical aggression across childhood and adolescence.

Inpatient aggression is a serious challenge in pediatric psychiatry. A chart review study in adolescent psychiatric inpatients consecutively admitted over 24 months was conducted, to describe aggressive events requiring an intervention (AERI) and to characterize their management. AERIs were identified based on specific institutional event forms and/or documentation of as-needed (STAT/PRN) medication administration for aggression, both recorded by nursing staff. Among 408 adolescent inpatients (age: 15.2±1.6 years, 43.9% male), 1349 AERIs were recorded, with ≥1 AERI occurring in 28.4% (n=116; AERI+). However, the frequency of AERIs was highly skewed (median 4, range: 1-258). In a logistical regression model, the primary diagnosis at discharge of disruptive behavior disorders and bipolar disorders, history of previous inpatient treatment, length of hospitalization, and absence of a specific precipitant prior to admission were significantly associated with AERIs (R(2)=0.32; p<0.0001). The first line treatment of patients with AERIs (AERI+) was pharmacological in nature (95.6%). Seclusion or restraint (SRU) was used at least once in 59.4% of the AERI+ subgroup (i.e., in 16.9% of all patients; median within-group SRU frequency: 3). Treatment and discharge characteristics indicated a poorer prognosis in the AERI+ (discharge to residential care AERI+: 22.8%, AERI-: 5.6%, p<0.001) and a greater need for psychotropic polypharmacy (median number of psychotropic medications AERI+: 2; AERI-: 1, p<0.001). Despite high rates of pharmacological interventions, SRU continue to be used in adolescent inpatient care. As both of these approaches lack a clear evidence base, and as adolescents with clinically significant inpatient aggression have increased illness acuity/severity and service needs, structured research into the most appropriate inpatient aggression management is sorely needed.

Glioblastoma, the most aggressive primary brain tumor, thrives in a microenvironment of relative immunosuppression within the relatively immune-privileged central nervous system. Despite treatments with surgery, radiation therapy, and chemotherapy, prognosis remains poor. The recent success of immunotherapy in the treatment of other cancers has renewed interest in vaccine therapy for the treatment of gliomas. In this article, we outline various immunotherapeutic strategies, review recent clinical trials data, and discuss the future of vaccine therapy for glioblastoma. PMID:22290259

Objective Researchers have endeavored for decades to develop and implement experimental assessments of sexual aggression and its precursors to capitalize on the many scientific advantages offered by laboratory experiments, such as rigorous control of key variables and identification of causal relationships. The purpose of this review is to provide an overview of and commentary on the evolution of these laboratory-based methods. Conclusions To date, two primary types of sexual aggression laboratory studies have been developed: those that involve behavioral analogues of sexual aggression and those that assess postulated precursors to sexually aggressive behavior. Although the study of sexual aggression in the laboratory is fraught with methodological challenges, validity concerns, and ethical considerations, advances in the field have resulted in greater methodological rigor, more precise dependent measures, and improved experimental validity, reliability, and realism. Because highly effective sexual aggression prevention strategies remain elusive, continued laboratory-based investigation of sexual aggression coupled with translation of critical findings to the development and modification of sexual aggression prevention programs remains an important task for the field.

Emotion Dysregulation as a Mechanism Linking Stress Exposure to Adolescent Aggressive Behavior

McLaughlin, Katie A.; Hatzenbuehler, Mark L.

2012-01-01

Exposure to stress is associated with a wide range of internalizing and externalizing problems in adolescents, including aggressive behavior. Extant research examining mechanisms underlying the associations between stress and youth aggression has consistently identified social information processing pathways that are disrupted by exposure to violence and increase risk of aggressive behavior. In the current study, we use longitudinal data to examine emotion dysregulation as a potential mechanism linking a broader range of stressful experiences to aggressive behavior in a diverse sample of early adolescents (N=1065). Specifically, we examined the longitudinal associations of peer victimization and stressful life events with emotion dysregulation and aggressive behavior. Structural equation modeling was used to create latent constructs of emotion dysregulation and aggression. Both stressful life events and peer victimization predicted subsequent increases in emotion dysregulation over a 4-month period. These increases in emotion dysregulation, in turn, were associated with increases in aggression over the subsequent 3 months. Longitudinal mediation models showed that emotion dysregulation mediated the relationship of both peer victimization (z=2.35, p=0.019) and stressful life events (z=2.32, p=0.020) with aggressive behavior. Increasing the use of adaptive emotion regulation strategies is an important target for interventions aimed at preventing the onset of adolescent aggressive behavior. PMID:22466516

This report describes the long-term outcomes of nonsurgical periodontal therapy and supportive periodontal treatment (SPT) of a 21-year-old patient affected by generalized aggressive periodontitis at multiple teeth with a compromised prognosis. After 25 years of SPT, no teeth had been extracted and no periodontal pockets associated with bleeding on probing were present. Radiographic analysis showed an improvement in infrabony defects, demonstrating long-term improvement is possible with nonsurgical periodontal treatment provided that smoking is not present and the patient is included in a strict SPT.

Gambling is relatively under-assessed in Veterans Affairs (VA) substance use disorder (SUD) treatment settings, yet shared characteristics with substance addiction suggest the importance of understanding how gambling behaviors present in Veterans seeking SUD care. We evaluated substance use, mental health, and violence-related correlates of past 30-day gambling among 833 Veterans (93% male, M age 48years, 72% Caucasian) seeking treatment in VA outpatient mental health and SUD clinics who completed screening for a randomized clinical trial. A total of 288 (35%) Veterans reported past 30-day gambling. Among those who gambled, 79% had cravings/urges to gamble, whereas between 20%-27% of gamblers reported perceived relationship, legal, and daily life problems related to gambling, as well as difficulty controlling gambling. A logistic regression analysis revealed that age, recent binge-drinking, and non-partner physical aggression were associated with recent gambling. Gambling was associated with binge-drinking and non-partner physical aggression, supporting potential shared characteristics among these behaviors such as impulsivity and risk-taking, which may complicate SUD treatment engagement and effectiveness. Findings support the need to screen for gambling in the VA, and to adapt treatments to include gambling as a potential behavioral target or relapse trigger, particularly among heavy drinking patients.

This approach may significantly enhance treatment outcome through the early detection and treatment of affected subjects, as well as using future approaches based on gene therapy. At present, the treatment of this disease is directed toward elimination of the subgingival bacterial load and other local risk factors. Adjunctive use of appropriate systemic antibiotics is recommended and may contribute to a longer suppression of the microbial infection. Other aggressive forms of periodontal diseases occur in patients who are affected with certain systemic diseases, including the leukocyte adhesion deficiency syndrome, Papillon-Lefèvre syndrome, Chediak-Higashi syndrome and Down syndrome. Management of the periodontal component of these diseases is very challenging. Acute gingival and periodontal lesions include a group of disorders that range from nondestructive to destructive forms, and these lesions are usually associated with pain and are a common reason for emergency dental consultations. Some of these lesions may cause a rapid and severe destruction of the periodontal tissues and loss of teeth. Oral infections, particularly acute infections, can spread to extra-oral sites and cause serious medical complications, and even death. Hence, prompt diagnosis and treatment are paramount. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Unintentional Misreporting on Self-Report Measures of Sexually Aggressive Behavior: An Interview Study.

2017-10-01

The development of effective sexual aggression prevention programs for men relies on data garnered from studies using self-report measures of sexual aggression perpetration. However, few studies have focused on understanding and improving self-report measures of sexual aggression perpetration. The current study used open-ended interviews to explore the nature and frequency of community men's (N = 34) unintentional misreporting-including both overreporting and underreporting-on two self-report measures of sexual aggression perpetration: the Sexual Experiences Survey-Long Form Perpetration (SES-LFP; Koss et al., 2007) and the Sexual Strategies Scale (SSS; Strang, Peterson, Hill, & Heiman, 2013a). Item misinterpretation led to both overreporting and underreporting of sexual aggression, although underreporting was more common. Men's interpretations of items, decision-making processes, and reasons for producing discrepant reports across measures were analyzed and discussed. Results could help inform efforts to refine self-report measurement of men's sexual aggression.

Psychopharmacologic treatment of borderline personality disorder

The best available evidence for psychopharmacologic treatment of borderline personality disorder (BPD) is outlined here. BPD is defined by disturbances in identity and interpersonal functioning, and patients report potential medication treatment targets such as impulsivity, aggression, transient psychotic and dissociative symptoms, and refractory affective instability Few randomized controlled trials of psychopharmacological treatments for BPD have been published recently, although multiple reviews have converged on the effectiveness of specific anticonvulsants, atypical antipsychotic agents, and omega-3 fatty acid supplementation. Stronger evidence exists for medication providing significant improvements in impulsive aggression than in affective or other interpersonal symptoms. Future research strategies will focus on the potential role of neuropeptide agents and medications with greater specificity for 2A serotonin receptors, as well as optimizing concomitant implementation of evidence-based psychotherapy and psychopharmacology, in order to improve BPD patients' overall functioning.

2010-01-01

This prospective study used longitudinal, multi-reporter data to examine the influence of parents’ marital relationship functioning on subsequent adolescent romantic relationships. Consistent with Bryant and Conger’s model for the development of early adult romantic relationships (DEARR; 2002), we found that interactional styles, more specifically paternal aggression and satisfaction, exhibited in parents’ marital relationship when their adolescents were age 13, were predictive of qualities of the adolescent’s romantic relationships five years later. Continuities were domain specific: paternal satisfaction predicted adolescent satisfaction and paternal aggression predicted adolescent aggression. Attachment security moderated the link between paternal aggression and subsequent adolescent aggression, with continuities between negative conflictual styles across relationships reduced for secure adolescents. Results are interpreted as suggesting that attachment may help attenuated the transmission of destructive conflict strategies across generations. PMID:20001139

Management Strategies for Aggressive Cushing's Syndrome: From Macroadenomas to Ectopics

Pozza, Carlotta; Graziadio, Chiara; Giannetta, Elisa; Lenzi, Andrea; Isidori, Andrea M.

2012-01-01

Cushing's syndrome (CS) is a rare but severe clinical condition represented by an excessive endogenous cortisol secretion and hence excess circulating free cortisol, characterized by loss of the normal feedback regulation and circadian rhythm of the hypothalamic-pituitary axis due to inappropriate secretion of ACTH from a pituitary tumor (Cushing's disease, CD) or an ectopic source (ectopic ACTH secretion, EAS). The remaining causes (20%) are ACTH independent. As soon as the diagnosis is established, the therapeutic goal is the removal of the tumor. Whenever surgery is not curative, management of patients with CS requires a major effort to control hypercortisolemia and associated symptoms. A multidisciplinary approach that includes endocrinologists, neurosurgeons, oncologists, and radiotherapists should be adopted. This paper will focus on traditional and novel medical therapy for aggressive ACTH-dependent CS. Several drugs are able to reduce cortisol levels. Their mechanism of action involves blocking adrenal steroidogenesis (ketoconazole, metyrapone, aminoglutethimide, mitotane, etomidate) or inhibiting the peripheral action of cortisol through blocking its receptors (mifepristone “RU-486”). Other drugs include centrally acting agents (dopamine agonists, somatostatin receptor agonists, retinoic acid, peroxisome proliferator-activated receptor γ “PPAR-γ” ligands) and novel chemotherapeutic agents (temozolomide and tyrosine kinase inhibitors) which have a significant activity against aggressive pituitary or ectopic tumors.

Aggressive behaviour by psychiatric patients is a serious issue in clinical practice, and adequate management of such behaviour is required, with careful evaluation of the factors causing the aggression. To examine the characteristics of aggressive incidents by ward type, a cross-sectional descriptive study was conducted for 6 months between April 2012 and June 2013 using the Staff Observation Aggression Scale - Revised, Japanese version (SOAS-R) in 30 wards across 20 Japanese psychiatric hospitals. Participating wards were categorized into three types based on the Japanese medical reimbursement system: emergency psychiatric, acute psychiatric, and standard wards (common in Japan, mostly treating non-acute patients). On analyzing the 443 incidents reported, results showed significant differences in SOAS-R responses by ward type. In acute and emergency psychiatric wards, staff members were the most common target of aggression. In acute psychiatric wards, staff requiring patients to take medication was the most common provocation, and verbal aggression was the most commonly used means. In emergency psychiatric wards, victims felt threatened. In contrast, in standard wards, both the target and provocation of aggression were most commonly other patients, hands were used, victims reported experiencing physical pain, and seclusion was applied to stop their behaviour. These findings suggest that ward environment was an important factor influencing aggressive behaviour. Ensuring the quality and safety of psychiatric care requires understanding the characteristics of incidents that staff are likely to encounter in each ward type, as well as implementing efforts to deal with the incidents adequately and improve the treatment environment. © 2016 Australian College of Mental Health Nurses Inc.

Children's aggressive responses to neutral peer behavior: a form of unprovoked reactive aggression.

2010-04-30

Previous studies that operationalized reactive aggression using behavioral observations in general populations have not taken into account the type of stimulus that elicits reactive aggression. In the present study we define a specific form of reactive aggression, i.e., reactive aggression in response to neutral behavior of a peer, which we will call unprovoked reactive aggression. We were specifically interested in children with severe aggressive behavior problems, since they may respond with reactive aggression even though the opponent did not clearly provoke them, but instead showed neutral behavior. Children with a disruptive behavior disorder (DBD) and normal control (NC) children participated in separate play sessions in which they played with a normal peer (NP). Children with DBD showed more unprovoked reactive aggression than NC children, during a cooperative game. Moreover, for children with DBD, unprovoked reactive aggressive behavior in this game correlated with parent-rated reactive aggression. Results of this study suggest that an unprovoked reactive form of aggression can be identified in children with DBD. Copyright (c) 2008. Published by Elsevier Ireland Ltd.

From hitting to tattling to gossip: an evolutionary rationale for the development of indirect aggression.

PubMed

Ingram, Gordon P D

2014-04-29

Adult humans are characterized by low rates of intra-group physical aggression. Since children tend to be more physically aggressive, an evolutionary developmental account shows promise for explaining how physical aggression is suppressed in adults. I argue that this is achieved partly through extended dominance hierarchies, based on indirect reciprocity and linguistic transmission of reputational information, mediated by indirectly aggressive competition. Reviewing the literature on indirect and related forms of aggression provides three pieces of evidence for the claim that evolutionarily old impulses towards physical aggression are socialized into indirect aggression in humans: (i) physical aggression falls in early childhood over the same age range at which indirect aggression increases; (ii) the same individuals engage in both direct and indirect aggression; and (iii) socially dominant individuals practice indirect aggression more frequently. Consideration of the developmental course of indirect aggression is complemented by analysis of similar developments in verbal behaviors that are not always thought of as aggressive, namely tattling and gossip. An important puzzle concerns why indirect aggression becomes more covert, and tattling more derogated, in preadolescence and adolescence. This may be due to the development of new strategies aimed at renegotiating social identity and friendship alliances in the peer group.

Chaïb, L S; Crocker, A G

2014-11-01

Aggressive behaviour is associated with certain personality traits in both the general population and among individuals with mental health problems, but little attention has been paid to the relationship between aggressive behaviour and personality among individuals with intellectual disabilities (ID). The aim of this study was to circumscribe personality profiles associated with aggressive behaviour among individuals with ID. In this cross-sectional study of 296 adults with mild or moderate ID, information on mental health, personality and aggressive behaviour was gathered through structured interviews with the ID participants and their case manager, and a review of client files. The results of the Reiss Profile were submitted to hierarchical cluster analysis method. Subsequently, the distribution of aggressive behaviour, sociodemographic characteristics and clinical characteristics across personality profiles was analysed. The analyses yielded seven distinct personality profiles in relation to patterns of aggressive behaviour: Pacifists, Socials, Confidents, Altruists, Conformists, Emotionals and Asocials. The identification of distinct personality profiles sheds light on the risk factors for aggressive behaviour, and suggests new approaches to improving diagnostic and intervention strategies. © 2013 The Authors.

Adverse childhood experiences, posttraumatic stress disorder symptoms, and emotional intelligence in partner aggression.

PubMed

Swopes, Rachael M; Simonet, Daniel V; Jaffe, Anna E; Tett, Robert P; Davis, Joanne L

2013-01-01

Intimate partner violence (IPV) has been linked to childhood abuse, posttraumatic stress disorder (PTSD), and low emotional intelligence (EI). Relationships among adverse childhood experiences (ACE), PTSD symptoms, and partner aggression (i.e., generalized tendency to aggress toward one's partner) were assessed in 108 male IPV offenders. It was hypothesized that ACE is positively correlated with partner aggression, PTSD mediates the ACE-aggression relationship, and the ACE-PTSD-aggression mediation varies by selected EI facets. Results indicate that ACE has an indirect effect on partner aggression via PTSD and PTSD mediates the ACE-aggression link when emotional self-regulation is low and when intuition (vs. reason) is high. Trauma-exposed IPV offenders may benefit from comprehensive treatments focusing on PTSD symptoms, emotional control, and reasoning skills to reduce aggression.

Finigan-Carr, Nadine M.; Gielen, Andrea; Haynie, Denise L.; Cheng, Tina L.

2015-01-01

Although research suggests gender differences in both forms and functions of aggressive behavior, there has been limited research into these types among African American early adolescents. This study examined the types and patterns of aggression in girls and boys in that group. Participants were 452 predominantly African American middle school youth (50.4% girls) aged 11-13 (X = 11.97) enrolled in three urban public schools. Students were invited to participate in a school-based intervention designed to prevent aggressive and deviant behaviors. Assessments occurred pre- and post-intervention. Surveys were analyzed to identify gender differences in the levels and types of aggressive behaviors, as well as differences in predictors of aggressive behaviors. Predictors were measured at baseline; aggressive behaviors at follow-up. There were significant gender differences in types of aggressive behaviors and their predictors indicating a need to develop and implement more suitable, gender-tailored prevention and treatment approaches.

Dating aggression occurs frequently in early to mid-adolescence and has negative repercussions for psychosocial adjustment and physical health. The patterns of behavior learned during this developmental timeframe may persist in future dating relationships, underscoring the need to identify risk factors for this outcome. The current study examined longitudinal relations between beliefs supporting aggression, anger regulation, and dating aggression. Participants were 176 middle school students in sixth, seventh, and eighth grade (50 % female; 82 % African American). No direct effects were found between beliefs supporting reactive or proactive aggression and dating aggression. Beliefs supporting reactive aggression predicted increased rates of anger dysregulation, and beliefs supporting proactive aggression led to subsequent increases in anger inhibition. Anger dysregulation and inhibition were associated with higher frequencies of dating aggression. An indirect effect was found for the relation between beliefs supporting reactive aggression and dating aggression via anger dysregulation. Another indirect effect emerged for the relation between beliefs supporting proactive aggression and dating aggression through anger inhibition. The study's findings suggested that beliefs supporting proactive and reactive aggression were differentially related to emotion regulation processes, and identified anger dysregulation and inhibition as risk factors for dating aggression among adolescents.

2008-01-01

Stereotactic amygdalotomy has been utilized as a surgical treatment for severe aggressive behavioral disorders. Several clinical studies have been reported since the first description of the procedure. In the current study, the authors reviewed the literature and evaluated the surgical results, neuropsychological outcome, and complication rate in patients who had undergone stereotactic amygdalotomy for severe aggressive behavioral disorders. The PubMed database was searched using the following terms: "amygdalotomy," "amygdalectomy," "amygdaloidectomy," "psychosurgery," "aggressive disorder," and "behavioral disorder." Clinical series with more than 5 patients undergoing stereotactic amygdalotomy for aggressive or other behavioral disorders were included in this review. The surgical technique, anatomical target, improvement in psychiatric symptomatology, postoperative employment and social rehabilitation, postoperative neurocognitive function, procedure-related complications, and long-term follow-up were evaluated. Thirteen clinical studies met our inclusion criteria. Reported postoperative improvement in aggressive behavior varied between 33 and 100%. Procedure-related complication rates ranged from 0 to 42%, whereas the mortality rate was as high as 3.8%. In the majority of the reviewed clinical series, the performance of stereotactic amygdalotomy did not compromise a patient's learning, language, and intellectual capabilities. The long-term follow-up, although very limited, revealed that initially observed improvement was maintained in most cases. Stereotactic amygdalotomy can be considered a valid surgical treatment option for carefully selected patients with medically refractory aggressive behavioral disorders. Recent advances in imaging and stereotactic navigation can further improve outcome and minimize the complication rate associated with this psychosurgical procedure.

Workplace aggression: beginning a dialogue.

McLemore, Monica R

2006-08-01

The June 2005 Clinical Journal of Oncology Nursing editorial titled "Communication: Whose Problem Is It?" (Griffin-Sobel, 2005) was written to begin a dialogue about a phenomenon frequently experienced yet rarely discussed: workplace aggression, also known as disruptive behavior. Prompted by a groundbreaking study published in the American Journal of Nursing by Rosenstein and O'Daniel (2005), the editorial challenged oncology nurses to begin to fix problems of communication. After reflecting on both of the articles and considering my own experience as a nurse manager, clinician, and scholar, I decided to explore the topic as it relates to nurse-to-nurse workplace aggression. The following is a summary of interviews with nurse managers, nurse practitioners, and nurse scientists about root causes and effective strategies to manage these sometimes complicated situations. This article is meant to continue the dialogue about the very sensitive issue. Confidentiality has been maintained, and I welcome your comments.

The Influence of Classroom Aggression and Classroom Climate on Aggressive-Disruptive Behavior

PubMed Central

Thomas, Duane E.; Bierman, Karen L.; Powers, CJ

2011-01-01

Research suggests that early classroom experiences influence the socialization of aggression. Tracking changes in the aggressive behavior of 4179 children from kindergarten to second-grade (ages 5–8) this study examined the impact of two important features of the classroom context–aggregate peer aggression and climates characterized by supportive teacher-student interactions. The aggregate aggression scores of children assigned to first-grade classrooms predicted the level of classroom aggression (assessed by teacher ratings) and quality of classroom climate (assessed by observers) that emerged by the end of grade 1. HLM analyses revealed that first-grade classroom aggression and quality of classroom climate made independent contributions to changes in student aggression, as students moved from kindergarten to second grade. Implications for policy and practice are discussed. PMID:21434887

Chronic anabolic-androgenic steroid treatment during adolescence increases anterior hypothalamic vasopressin and aggression in intact hamsters.

PubMed

Harrison, R J; Connor, D F; Nowak, C; Nash, K; Melloni, R H

2000-05-01

The present study examines the hypothesis that exposure to anabolic-androgenic steroids (AAS) during adolescent development predisposes hamsters to heightened levels of aggressive behavior by influencing the anterior hypothalamic-arginine vasopressin (AH-AVP) neural system. To test this, adolescent male hamsters (Mesocricetus auratus) were treated with high doses of AAS, tested for offensive aggression in the absence or presence of AH-AVP receptor antagonists, and then examined for changes in AH-AVP expression and neural organization. AAS exposure during adolescence significantly increased aggression intensity (number of attacks and bites) and initiation (latency to the first bite). Yet, only increases in aggression intensity were inhibited by AH-AVP receptor antagonism. Adolescent AAS-treated hamsters showed significant increases in AH-AVP fiber density and peptide content. However, no alterations in AH-AVP neuronal organization or mRNA expression were found. Together, these data suggest that adolescent AAS exposure increase aggression intensity by altering AH-AVP expression and activity, providing direct evidence for a causal role of AH-AVP expression and function in early onset AAS-stimulated aggression.

Clinical correlates of verbal aggression, physical aggression and inappropriate sexual behaviour after brain injury.

James, Andrew I W; Young, Andrew W

2013-01-01

To explore the relationships between verbal aggression, physical aggression and inappropriate sexual behaviour following acquired brain injury. Multivariate statistical modelling of observed verbal aggression, physical aggression and inappropriate sexual behaviour utilizing demographic, pre-morbid, injury-related and neurocognitive predictors. Clinical records of 152 participants with acquired brain injury were reviewed, providing an important data set as disordered behaviours had been recorded at the time of occurrence with the Brain Injury Rehabilitation Trust (BIRT) Aggression Rating Scale and complementary measures of inappropriate sexual behaviour. Three behavioural components (verbal aggression, physical aggression and inappropriate sexual behaviour) were identified and subjected to separate logistical regression modelling in a sub-set of 77 participants. Successful modelling was achieved for both verbal and physical aggression (correctly classifying 74% and 65% of participants, respectively), with use of psychotropic medication and poorer verbal function increasing the odds of aggression occurring. Pre-morbid history of aggression predicted verbal but not physical aggression. No variables predicted inappropriate sexual behaviour. Verbal aggression, physical aggression and inappropriate sexual behaviour following acquired brain injury appear to reflect separate clinical phenomena rather than general behavioural dysregulation. Clinical markers that indicate an increased risk of post-injury aggression were not related to inappropriate sexual behaviour.

Exploring a taxonomy for aggression against women: can it aid conceptual clarity?

PubMed

Cook, Sarah; Parrott, Dominic

2009-01-01

The assessment of aggression against women is demanding primarily because assessment strategies do not share a common language to describe reliably the wide range of forms of aggression women experience. The lack of a common language impairs efforts to describe these experiences, understand causes and consequences of aggression against women, and develop effective intervention and prevention efforts. This review accomplishes two goals. First, it applies a theoretically and empirically based taxonomy to behaviors assessed by existing measurement instruments. Second, it evaluates whether the taxonomy provides a common language for the field. Strengths of the taxonomy include its ability to describe and categorize all forms of aggression found in existing quantitative measures. The taxonomy also classifies numerous examples of aggression discussed in the literature but notably absent from quantitative measures. Although we use existing quantitative measures as a starting place to evaluate the taxonomy, its use is not limited to quantitative methods. Implications for theory, research, and practice are discussed.

Alcohol Expectancies and Evaluations of Aggression in Alcohol-Related Intimate-Partner Verbal and Physical Aggression

Kachadourian, Lorig K; Quigley, Brian M; Leonard, Kenneth E

2014-01-01

Objective: Alcohol aggression expectancies have been found to be associated with increases in aggressive behavior. However, research has not consistently examined evaluations of such behavior. This is unfortunate as both expectancies and evaluations may play a role in whether such behavior will occur. Given this, the current study cross-sectionally examined the associations between alcohol aggression expectancies, evaluations of alcohol-related aggression, indicators of excessive drinking, and alcohol-related verbal and physical aggression. Method: The sample consisted of 280 married and cohabiting couples. These couples reported on excessive drinking indicators, alcohol expectancies and evaluations, and alcohol-related verbal and physical aggression during the past year. Results: Findings showed that verbal aggression was positively associated with indicators of excessive drinking among females and with alcohol aggression expectancies for females who evaluated such aggression positively. For males, aggression expectancies and indicators of excessive drinking were positively associated with verbal aggression. For physical aggression, results showed that indicators of excessive drinking and aggression expectancies were associated with physical aggression for females. For males, aggression expectancies were positively associated and evaluations were negatively associated with physical aggression. Conclusions: These findings add to previous research on alcohol aggression expectancies in close relationships and emphasize the importance of considering evaluations of alcohol-related behavior and how they may play a role in intimate-partner violence and aggression.

Objectives This study compared results of aggressive and nonaggressive debridement protocols for the treatment of high energy open supracondylar femur fractures after the primary procedure, with respect to the requirement for secondary bone grafting procedures, and deep infection. Design Retrospective review Setting Level I and Level II Trauma Centers Patients/Participants Twenty-nine consecutive patients with high grade open (Gustilo Types II and III) supracondylar femur fractures (OTA/AO 33A and C) treated with debridement and locked plating. Intervention Surgeons at two different Level I trauma centers had different debridement protocols for open supracondylar femur fractures. One center used a More Aggressive (MA)protocol in their patients (n=17) that included removal of all devitalized bone and placement of antibiotic cement spacers to fill large segmental defects. The other center used a Less Aggressive (LA) protocol in their patients (n=12) that included debridement of grossly contaminated bone with retention of other bone fragments and no use of antibiotic cement spacers. All other aspects of the treatment protocol at the two centers were similar: definitive fixation with locked plates in all cases; IV antibiotics were used until definitive wound closure; and weight bearing was advanced upon clinical and radiographic evidence of fracture healing. Main Outcome Measurements Healing after the primary procedure, requirement for secondary bone grafting procedures, and the presence of deep infection. Results Demographics were similar between included patients at each center with regard to: age; gender; rate of open fractures; open fracture classification; mechanism; and smoking (p>.05). Patients at the MA center were more often diabetic (p<.05).Cement spacers to fill segmental defects were used more often after MA debridement (35% vs 0%, p<0.006) and more patients had a plan for staged bone grafting after MA debridement (71% vs 8%, p<0.006).

Jia, Shoumei; Wang, Ling; Shi, Yingjuan; Li, Ping

The study explored family predictors of aggressive behavior in preschool children in China. Using a stratified cluster sampling method, 1382 preschool children were recruited from ten kindergarten schools in Shanghai, China. Their parents completed the Child Behavior Checklist (CBCL)-aggression subscale, the Parent Behavior Inventory, the Family Environment Scale, and a demographic questionnaire. The mean age of the 1382 children was 4.97years (SD=.88), with 55.1% (762) boys, and 44.9% (620) girls. According to the CBCL, the prevalence of aggressive behavior in preschool children was 12.4%. Multivariate logistic regression analysis showed that family conflicts (OR = 1.231, 95% CI: 1.115-1.360), hostile/coercive parenting (OR = 1.083, 95% CI: 1.051-1.116), inconsistent parenting between grandparents and parents (OR = 1.658, 95% CI: 1.175-2.341), and more time spent watching TV (OR = 1.999, 95% CI: 1.568-2.550) significantly predicted aggressive behavior of children. Children with more family conflicts who experience hostile/coercive parenting were more likely to engage in aggressive behavior. Moreover, inconsistent parenting attitudes between grandparents and parents, and excessive TV exposure also contributed to childhood aggression. Given that the results of this study show a high prevalence of aggressive behavior in preschool children, future research must pay greater attention to this aspect. Family risk factors identified as relevant to children's aggression in this study provide avenues to develop family-focused strategies for curbing aggression in preschool children.

This study aimed to examine the effect of group-based psychodrama therapy on the level aggression in adolescents. The study included 23 students from Nezihe Yalvac Anatolian Vocational High School of Hotel Management and Tourism that had high aggression scores. Eleven of the participants (6 female, 5 male) constituted the experimental group and 12 (6 male, 6 female) were in the control group. The 34-item Aggression Scale was used to measure level of aggression. We utilized mixed pattern design including experiment-control, pre-test and post test and follow up. The experimental group participated in group-based psychodrama therapy once a week for 90 minutes, for 14 weeks in total. The Aggression Scale was administered to the experimental and control groups before and after treatment; it was additionally administered to the experimental group 16 weeks after treatment. Data were analyzed using ANCOVA and dependent samples t tests. Our analysis shows that group-based psychodrama had an effect on the experimental group in terms of total aggression, anger, hostility, and indirect aggression scores (F=65.109, F=20.175, F=18.593, F=40.987, respectively, P<.001). There was no effect of the group-based treatment on verbal or physical aggression scores. Follow-up indicated that the effect of the therapy was still measureable 16 weeks after the cessation of the therapy. Results of the present study indicate that group-based psychodrama therapy decreased the level of aggression in the experimental group. Current findings are discussed with reference to the literature. Recommendations for further research and for psychiatric counselors are provided.

Intra- Versus Intersex Aggression: Testing Theories of Sex Differences Using Aggression Networks.

PubMed

Wölfer, Ralf; Hewstone, Miles

2015-08-01

Two theories offer competing explanations of sex differences in aggressive behavior: sexual-selection theory and social-role theory. While each theory has specific strengths and limitations depending on the victim's sex, research hardly differentiates between intrasex and intersex aggression. In the present study, 11,307 students (mean age = 14.96 years; 50% girls, 50% boys) from 597 school classes provided social-network data (aggression and friendship networks) as well as physical (body mass index) and psychosocial (gender and masculinity norms) information. Aggression networks were used to disentangle intra- and intersex aggression, whereas their class-aggregated sex differences were analyzed using contextual predictors derived from sexual-selection and social-role theories. As expected, results revealed that sexual-selection theory predicted male-biased sex differences in intrasex aggression, whereas social-role theory predicted male-biased sex differences in intersex aggression. Findings suggest the value of explaining sex differences separately for intra- and intersex aggression with a dual-theory framework covering both evolutionary and normative components. © The Author(s) 2015.

Relationship between boys' normative beliefs about aggression and their physical, verbal, and indirect aggressive behaviors.

PubMed

Lim, Si Huan; Ang, Rebecca P

2009-01-01

This study examined the contribution of general normative beliefs about aggression and specific normative beliefs about retaliatory aggression in predicting physical, verbal, and indirect aggressive behaviors. Two hundred and forty-nine Grade 4 and Grade 5 boys completed the Normative Beliefs about Aggression Scale (NOBAGS) and provided self-reports on the frequency of their physical, verbal, and indirect aggressive behaviors. A series of hierarchical multiple regression analyses revealed that general normative beliefs about aggression contributed significantly in predicting all three types of aggressive behaviors. When general normative beliefs about aggression were controlled for, specific normative beliefs about retaliatory aggression against males but not specific normative beliefs about retaliatory aggression against females, contributed significantly to predict physical, verbal, and indirect aggressive behaviors. Implications for intervention programs are discussed.

The aim of this study was to identify the existence of combinations of aggression components (Anger, Hostility, Physical Aggression and Verbal Aggression) that result in different profiles of aggressive behavior in children, as well as to test the differences between these profiles in scores of perfectionism, school refusal and affect. It is interesting to analyze these variables given: (a) their clinical relevance due to their close relationship with the overall psychopathology; and (b) the need for further evidence regarding how they are associated with aggressive behavior. The sample consisted of 1202 Spanish primary education students between the ages of 8 and 12. Three aggressive behavior profiles for children were identified using Latent Class Analysis (LCA): High Aggression (Z scores between 0.69 and 0.7), Moderate Aggression (Z scores between −0.39 and −0.47) and Low Aggression (Z scores between −1.36 and −1.58). These profiles were found for 49.08%, 38.46% and 12.48% of the sample, respectively. High Aggression scored significantly higher than Moderate Aggression and Low Aggression on Socially Prescribed Perfectionism (SPP), Self-Oriented Perfectionism (SOP), the first three factors of school refusal (i.e., FI. Negative Affective, FII. Social Aversion and/or Evaluation, FIII. To Pursue Attention), and Negative Affect (NA). In addition, Moderate Aggression also reported significantly higher scores than Low Aggression for the three first factors of school refusal and NA. Conversely, Low Aggression had significantly higher mean scores than High Aggression and Moderate Aggression on Positive Affect (PA). Results demonstrate that High Aggression was the most maladaptive profile having a high risk of psychological vulnerability. Aggression prevention programs should be sure to include strategies to overcome psychological problems that characterize children manifesting high levels of aggressive behavior. PMID:29441002

2015-12-01

The oxytocin receptor is important in several domains of social behavior, and administration of oxytocin modulates social responding in several mammalian species, including humans. Oxytocin has both therapeutic and scientific potential for elucidating the neural and behavioral mechanisms governing social behavior. In the present study, operationally-defined aggressive behavior of six males with Antisocial Personality Disorder (ASPD) was measured following acute intranasal oxytocin dosing (12, 24, and 48 international units) and placebo, using a well-validated laboratory task of human aggression (Point-Subtraction Aggression Paradigm, or PSAP). The PSAP provides participants with concurrently available monetary-earning and operationally-defined aggressive response options, maintained by fixed ratio schedules of consequences. Shifts in response rates and inter-response time (IRT) distributions were observed on the aggressive response option following oxytocin doses, relative to placebo. Few changes were observed in monetary-reinforced responding. However, across participants the direction and magnitude of changes in aggressive responding were not systematically related to dose. No trends were observed between psychometric or physiological data and oxytocin dosing or aggressive behavior. While this report is to our knowledge the first to examine the acute effects of oxytocin in this population at high risk for violence and other forms of antisocial behavior, several limitations in the experimental design and the results cast the study as a preliminary report. Strategies for more extensive future projects are discussed.

Previous measures of aggressive personality have focused on direct aggression (i.e., retaliation toward the provoking agent). An original self-report measure of trait displaced aggression is presented. Exploratory and confirmatory factor analyses provided support for a 3-factor conceptualization of the construct. These analyses identified an affective dimension (angry rumination), a cognitive dimension (revenge planning), and a behavioral dimension (general tendency to engage in displaced aggression). The trait measure demonstrated good internal consistency and test-retest reliability as well as convergent and discriminant construct validity. Unlike other related personality measures, trait displaced aggression significantly predicted indirect indicators of real-world displaced aggression (i.e., self-reported domestic abuse and road rage) as well as laboratory displaced aggression in 2 experiments.

Aggression is a universal social behavior important for the acquisition of food, mates, territory, and social status. Aggression in Drosophila is context-dependent and can thus be expected to involve inputs from multiple sensory modalities. Here, we use mechanical disruption and genetic approaches in Drosophila melanogaster to identify hearing as an important sensory modality in the context of intermale aggressive behavior. We demonstrate that neuronal silencing and targeted knockdown of hearing genes in the fly's auditory organ elicit abnormal aggression. Further, we show that exposure to courtship or aggression song has opposite effects on aggression. Our data define the importance of hearing in the control of Drosophila intermale aggression and open perspectives to decipher how hearing and other sensory modalities are integrated at the neural circuit level.

Although family violence perpetrated by juveniles has been acknowledged as a potentially serious form of violence for over 30years, scientific studies have been limited to examining the incidence and form of home violence. The present study examined the prevalence of family aggression as perpetrated by youths; we examined groups drawn from clinic-referred and forensic samples. Two audits of case files were conducted to systematically document aggression perpetrated by referred youths toward their family members. The purpose of the first audit was fourfold: i) to identify the incidence of the perpetration of family aggression among clinical and forensic samples; ii) to identify whether there were any reports of weapon use during aggressive episodes; iii) to identify the target of family aggression (parents or siblings); and iv) to identify the form of aggression perpetrated (verbal or physical). The second audit aimed to replicate the findings and to show that the results were not due to differences in multiple deprivation indices, clinical diagnosis of disruptive behavior disorders, and placement into alternative care. A sampling strategy was designed to audit the case notes of 25 recent forensic Child and Adolescent Mental Health Service (CAMHS) cases and 25 demographically similar clinic-referred CAMHS cases in the first audit; and 35 forensic cases and 35 demographically similar clinic-referred CAMHS cases in the second audit. Using ordinal chi-square, the forensic sample (audit 1=64%; audit 2=82.9%) had greater instances of family violence than the clinical sample (audit 1=32%; audit 2=28.6%). They were more likely to use a weapon (audit 1=69%; audit 2=65.5%) compared to the clinical sample (audit 1 and 2=0%). Examining only the aggressive groups, there was more perpetration of aggression toward parents (audit 1, forensic=92%, clinical=75%; audit 2, forensic=55.17%, clinical=40%) than toward siblings (audit 1, forensic=43%, clinical=50%; audit 2, forensic=27

Vertebral hemangioma (VH) is virtually vascular malformation, which is usually asymptomatic. Only 3.7 % of VH may become active and symptomatic, and 1 % may invade the spinal canal and/or paravertebral space. Treatment protocols for active or aggressive VHs are still in controversy. Reported treatments include radiotherapy, vertebroplasty, direct alcohol injection, embolization, surgery and a combination of these modalities. A 41-year-old lady was presented with 18 month history of intermittent back pain. CT revealed T5 osteolytic lesion with epidural and paravertebral extension. The first CT guided biopsy yielded little information. Histopathological diagnosis of the second biopsy was VH. Vertebroplasty, posterior decompression and fixation were performed followed by postoperative radiotherapy. Her symptoms were resolved immediately after the operation. At 12 months follow-up, no recurrence was detected by CT with contrast enhancement. Surgical decompression, vertebroplasty and fixation are safe and effective for aggressive VH. More attention is needed in determining the algorithm for the diagnosis and treatment of aggressive VH.

Aggression is a universal social behavior important for the acquisition of food, mates, territory, and social status. Aggression in Drosophila is context-dependent and can thus be expected to involve inputs from multiple sensory modalities. Here, we use mechanical disruption and genetic approaches in Drosophila melanogaster to identify hearing as an important sensory modality in the context of intermale aggressive behavior. We demonstrate that neuronal silencing and targeted knockdown of hearing genes in the fly’s auditory organ elicit abnormal aggression. Further, we show that exposure to courtship or aggression song has opposite effects on aggression. Our data define the importance of hearing in the control of Drosophila intermale aggression and open perspectives to decipher how hearing and other sensory modalities are integrated at the neural circuit level.

Minimally-aggressive gestational trophoblastic neoplasms.

PubMed

Cole, Laurence A

2012-04-01

We have previously defined a new syndrome "Minimally-aggressive gestational trophoblastic neoplasms" in which choriocarcinoma or persistent hydatidiform mole has a minimal growth rate and becomes chemorefractory. Previously we described a new treatment protocol, waiting for hCG rise to >3000 mIU/ml and disease becomes more advanced, then using combination chemotherapy. Initially we found this treatment successful in 8 of 8 cases, here we find this protocol appropriate in a further 16 cases. Initially we used hyperglycosylated hCG, a limited availability test, to identify this syndrome. Here we propose also using hCG doubling rate to detect this syndrome. Minimally aggressive gestational trophoblastic disease can be detected by chemotherapy resistance or low hyperglycosylated hCG, <40% of total hCG. It can also be identified by hCG doubling rate, with doubling time greater than 2 weeks. Nineteen new cases were identified as having minimally aggressive gestational trophoblastic disease by hyperglycosylated hCG and by hCG doubling test. All were recommended to hold off further chemotherapy until hCG >3000mIU/ml. One case died prior to the start of the study, one case withdrew because of a lung nodule and one withdrew refusing the suggested combination chemotherapy. The remaining 16 women were all successfully treated. A total of 8 plus 16 or 24 of 24 women were successfully treated using the proposed protocol, holding back on chemotherapy until hCG >3000mIU/ml.

This study uses behavior genetic (BG) methodology to investigate Freud’s theory of depression as aggression directed toward the self (1930) and the extent to which genetically and environmentally influenced aggressive tendencies contribute to depressive symptoms. Data from the Twin and Offspring Study in Sweden (TOSS) is used to demonstrate how, in estimating shared and unique environmental influences, BG methods can inform psychoanalytic theory and practice, particularly because of their shared emphasis on the importance of individual experience in development. The TOSS sample consists of 909 pairs of adult twins, their partners, and one adolescent child per couple. The Center for Epidemiologic Studies Depression Scale (Radloff 1977) was used to measure depressive symptoms and the Karolinska Scales of Personality (Schalling and Edman 1993) to measure internally directed aggression. Genetic analyses indicated that for both men and women, their unique experiences as well as genetic factors contributed equally to the association between internally directed aggression and depressive symptoms. These findings support Freud’s theory that constitutionally based differences in aggression, along with individual experiences, contribute to a person’s depressive symptoms. Establishing that an individual’s unique, not shared, experiences and perceptions contribute to depressive symptoms and internally directed aggression reinforces the use of patient-specific treatment approaches implemented in psychoanalytic psychotherapy or psychoanalysis.

The object of my aggression: Sexual objectification increases physical aggression toward women.

Vasquez, Eduardo A; Ball, Louisa; Loughnan, Steve; Pina, Afroditi

2018-01-01

Objectification involves reducing someone to a sexual object, rather than seeing them as a full person. Despite numerous theoretical claims that people are more aggressive toward the objectified, and empirical evidence that objectification is linked to high willingness to aggress, rape proclivity, and aggressive attitudes, no research has examined a causal link between objectification and physical aggression, particularly in the context of provocation. In two experiments, we examined this predicted link. In Experiment 1, using a 2 (objectification: no/yes) × 2 (provocation: no/yes) factorial between-subjects design, we investigated the effects of objectification, induced via body focus during a face-to-face interaction, and provocation on physical aggression toward a female confederate. Our results revealed a significant main effect of provocation, a marginal main effect of objectification, and a significant interaction between these variables. In the absence of a provocation, focusing on a woman's body increased aggression toward her. Experiment 2 replicated Experiment 1 using a video of a target woman instead of a face-to-face interaction. Again, our results showed a significant two-way interaction between objectification and provocation, wherein objectification increased aggression in the absence of provocation. Overall, this research indicates that objectification can lead to heightened physical aggression toward objectified women. © 2017 Wiley Periodicals, Inc.

Double hit lymphoma or triple hit lymphoma (DHL/THL) is a rare form of aggressive B-Cell Lymphoma. Overexpression of MYC, BCL2 or/and BCL6 due to genomic rearrangements are the key molecular features of DHL/THL. Patients with DHL/THL show very aggressive disease course and poor survival due to the lack of effective treatment modalities. Here, we established new THL cell model and assessed its in vitro growth characteristics along with the DHL cell line in response to potent MYC inhibitors, 10058-F4 and JQ-1, and a BCL2 inhibitor, ABT-199, with or without chemotherapeutic agent vincristine or doxorubicin. We found that 10058-F4, JQ-1 or ABT-199 exposure as a single agent inhibited the growth of DHL/THL cells in a dose-dependent manner. Combined exposure of 10058-F4 or JQ-1 and ABT-199 as well as vincristine or doxorubicin markedly suppressed the growth of DHL/THL cells compared with the single treatment. As assessed by multiple approaches, apoptosis induced by ABT-199, 10058-F4 or JQ-1 was underlying cause of the observed growth suppression. These findings suggest that co-inhibition of MYC and BCL2 signaling is a promising therapeutic strategy for patients with DHL/THL lymphomas. Copyright © 2015 Elsevier Ltd. All rights reserved.

To examine the implications of an ontology of aggressive behavior which divides aggression into reactive, affective, defensive, impulsive (RADI) or "emotionally hot"; and planned, instrumental, predatory (PIP) or "emotionally cold." Recent epidemiological, criminological, clinical and neuroscience studies converge to support a connection between emotional and trauma related psychopathology and disturbances in the emotions, self-regulation and aggressive behavior which has important implications for diagnosis and treatment, especially for delinquent populations. Selective review of preclinical and clinical studies in normal, clinical and delinquent populations. In delinquent populations we observe an increase in psychopathology, and especially trauma related psychopathology which impacts emotions and self-regulation in a manner that hotly emotionally charged acts of aggression become more likely. The identification of these disturbances can be supported by findings in cognitive neuroscience. These hot aggressive acts can be delineated from planned or emotionally cold aggression. Our findings support a typology of diagnostic labels for disruptive behaviors, such as conduct disorder and oppositional defiant disorder, as it appears that these acts of hot emotional aggression are a legitimate target for psychopharmacological and other trauma specific interventions. The identification of this subtype of disruptive behavior disorders leads to more specific clinical interventions which in turn promise to improve hitherto unimpressive treatment outcomes of delinquents and patients with disruptive behavior.

Cruel intentions on television and in real life: can viewing indirect aggression increase viewers' subsequent indirect aggression?

Coyne, Sarah M; Archer, John; Eslea, Mike

2004-07-01

Numerous studies have shown that viewing violence in the media can influence an individual's subsequent aggression, but none have examined the effect of viewing indirect aggression. This study examines the immediate effect of viewing indirect and direct aggression on subsequent indirect aggression among 199 children ages 11 to 14 years. They were shown an indirect, direct, or no-aggression video and their subsequent indirect aggression was measured by negative evaluation of a confederate and responses to a vignette. Participants viewing indirect or direct aggression gave a more negative evaluation of and less money to a confederate than participants viewing no-aggression. Participants viewing indirect aggression gave less money to the confederate than those viewing direct aggression. Participants viewing indirect aggression gave more indirectly aggressive responses to an ambiguous situation and participants viewing direct aggression gave more directly aggressive responses. This study provides the first evidence that viewing indirect aggression in the media can have an immediate impact on subsequent aggression.

Studies into abnormal aggression in humans and rodents: Methodological and translational aspects.

PubMed

Haller, Jozsef

2017-05-01

Here we review the principles based on which aggression is rendered abnormal in humans and laboratory rodents, and comparatively overview the main methodological approaches based on which this behavior is studied in the two categories of subjects. It appears that the discriminating property of abnormal aggression is rule breaking, which renders aggression dysfunctional from the point of view of the perpetrator. We show that rodent models of abnormal aggression were created by the translation of human conditions into rodent equivalents, and discuss how findings obtained with such models may be "translated back" to human conditions when the mechanisms underlying aggression and its possibilities of treatment are investigated. We suggest that the complementary nature of human and rodent research approaches invite a more intense cross-talk between the two sides of aggression research than the one presently observed.

BACKGROUND The management of neuropsychiatric symptoms (NPS) such as agitation and aggression is a major priority in caring for people with Alzheimer’s disease (AD). Agitation and aggression (A/A) are among the most disruptive symptoms, and given their impact, they are increasingly an important target for development of effective treatments. Considerable progress has been made in the last years with a growing number of randomized controlled trials (RCTs) of drugs for NPS. The limited benefits reported in some RCTs may be accounted for by the absence of a biological link of the tested molecule to NPS and also by key methodological issues. In recent RCTs of A/A, a great heterogeneity design was found. Designing trials for dementia populations with NPS presents many challenges, including identification of appropriate participants for such trials, engagement and compliance of patients and caregivers in the trials and the choice of optimal outcome measures to demonstrate treatment effectiveness. The EU/US -CTAD Task Force, an international collaboration of investigators from academia, industry, non-profit foundations, and regulatory agencies met in Philadelphia on November 19, 2014 to address some of these challenges. Despite potential heterogeneity in clinical manifestations and neurobiology, agitation and aggression seems to be accepted as an entity for drug development. The field appears to be reaching a consensus in using both agitation and aggression (or other NPS)-specific quantitative measures plus a global rating of change for agitation outcomes based on clinician judgment as the main outcomes.

A 16-year-old boy, who had been initially examined for bilateral blepharedema and slight eruption, presented with rapidly deteriorating symptoms in associating with headache and consciousness disturbance. He was diagnosed to have primary cutaneous CD8-positive aggressive epidermotropic cytotoxic T-cell lymphoma (PCAE-CTL) by a biopsy of the skin and brain. After whole-brain radiation and some courses of chemotherapy, cord blood transplantation was performed with myeloablative conditioning. After transplantation, the cerebral dysfunction gradually improved. Disease remission was confirmed by the disappearance of any abnormal findings on electroencephalogram and magnetic resonance imaging. PCAE-CTL is reported to be an extremely aggressive disease with a poor prognosis, but the timely performance of cord blood transplantation is considered to be a promising treatment strategy.

Hostile Attribution Bias as a Mediator of the Relationships of Psychopathy and Narcissism With Aggression.

PubMed

Law, Helen; Falkenbach, Diana M

2017-11-01

Hostile attribution bias (HAB), the tendency to perceive hostility in ambiguous situations, has been linked to aggressive outcomes, such as reactive aggression. HAB has been connected to personality types involving hostile beliefs and reactive aggression, including narcissism and psychopathy. Specifically, secondary psychopathy is associated with HAB and reactive aggression. Despite research and theory connecting these constructs, few studies have examined if HAB mediates the relationships among psychopathy, narcissism, and aggression. The current study explores this possible mediation in an urban college sample. Narcissism was associated with aggression but not hostile aggression or HAB. Reactive aggression and HAB were both associated with psychopathy, but there were no mediation relationships. The associations with aggression may be, therefore, due to underlying traits of secondary psychopathy rather than the hostile attributions to which the traits contribute; consequently, treatments focused on reducing aggressive responses by correcting interpretations of social situations may not be successful.

Aggression in children with behavioural/emotional difficulties: seeing aggression on television and video games.

Mental health professionals are often asked to give advice about managing children's aggression. Good quality evidence on contributory environmental factors such as seeing aggression on television and in video games is relatively lacking, although societal and professional concerns are high. This study investigated possible associations between seeing aggression in such media and the aggressive behaviour of children attending specialist outpatient child and adolescent mental health services (CAMHS). In this mixed methods study, forty-seven British children aged 7-11 years with behavioural/emotional difficulties attending CAMHS and their carers participated in a survey; twenty purposively-selected children and a parent/carer of theirs participated in a qualitative study, involving semi-structured interviews, analysed using the Framework Analysis Approach; findings were integrated. Children attending CAMHS exhibit clinically significant aggression, of varying types and frequency. They see aggression in multiple real and virtual settings. Verbal aggression was often seen, frequently exhibited and strongly associated with poor peer relationships and low prosocial behaviour. Children did not think seeing aggression influences their own behaviour but believed it influences others. Carers regarded aggression as resulting from a combination of inner and environmental factors and seeing aggression in real-life as having more impact than television/video games. There is yet no definitive evidence for or against a direct relationship between aggression seen in the media and aggression in children with behavioural/emotional difficulties. Future research should take an ecological perspective, investigating individual, developmental and environmental factors. Carers, professional organisations and policy makers should address aggression seen in all relevant area of children's lives, primarily real-life and secondly virtual environments.

2012-08-01

This study evaluates efficacy and effectiveness of 'Doing Anger Differently' (DAD), a group treatment for reactively aggressive 12-15 year old males. DAD uses percussion exercises to aid treatment. Study 1 compared a ten-week treatment with a waitlist control at pre, post and 6 month (treatment group only) follow-up. Study 2 replicated Study 1, but also followed up controls at 6 months. In study 1 (N = 54) the treatment resulted in lowered trait anger (Cohen's d = -1.3), aggression-reports (d = -1.0) and depression (d = -0.6), and increased self-esteem (d = 0.6), all maintained at six months. In study 2 (N = 65), aggression-reports fell to one fifth of pre-treatment levels at nine months follow-up (d = -1.2), with lowered trait anger (d = -0.4) and anger expression (d = -0.3) post-treatment.

Aggressiveness, violence, homicidality, homicide, and Lyme disease

2018-01-01

Background No study has previously analyzed aggressiveness, homicide, and Lyme disease (LD). Materials and methods Retrospective LD chart reviews analyzed aggressiveness, compared 50 homicidal with 50 non-homicidal patients, and analyzed homicides. Results Most aggression with LD was impulsive, sometimes provoked by intrusive symptoms, sensory stimulation or frustration and was invariably bizarre and senseless. About 9.6% of LD patients were homicidal with the average diagnosis delay of 9 years. Postinfection findings associated with homicidality that separated from the non-homicidal group within the 95% confidence interval included suicidality, sudden abrupt mood swings, explosive anger, paranoia, anhedonia, hypervigilance, exaggerated startle, disinhibition, nightmares, depersonalization, intrusive aggressive images, dissociative episodes, derealization, intrusive sexual images, marital/family problems, legal problems, substance abuse, depression, panic disorder, memory impairments, neuropathy, cranial nerve symptoms, and decreased libido. Seven LD homicides included predatory aggression, poor impulse control, and psychosis. Some patients have selective hyperacusis to mouth sounds, which I propose may be the result of brain dysfunction causing a disinhibition of a primitive fear of oral predation. Conclusion LD and the immune, biochemical, neurotransmitter, and the neural circuit reactions to it can cause impairments associated with violence. Many LD patients have no aggressiveness tendencies or only mild degrees of low frustration tolerance and irritability and pose no danger; however, a lesser number experience explosive anger, a lesser number experience homicidal thoughts and impulses, and much lesser number commit homicides. Since such large numbers are affected by LD, this small percent can be highly significant. Much of the violence associated with LD can be avoided with better prevention, diagnosis, and treatment of LD. PMID:29576731

2014-01-01

This chapter describes the state of knowledge on the development of physical aggression from early childhood to adulthood, the long term outcomes of chronic physical aggression during childhood and the risk factors for chronic physical aggression. Unraveling the development of physical aggression is important to understand when and why humans start using physical aggression, to understand why some humans suffer from chronic physical aggression and to understand how to prevent the development of this disorder which causes much distress to the aggressors and their victims. The study of the developmental origins of aggression also sheds light on the reasons why situational prevention of aggression is important at all ages and in all cultures.

Desensitization to Media Violence: Links With Habitual Media Violence Exposure, Aggressive Cognitions, and Aggressive Behavior

This study examined the links between desensitization to violent media stimuli and habitual media violence exposure as a predictor and aggressive cognitions and behavior as outcome variables. Two weeks after completing measures of habitual media violence exposure, trait aggression, trait arousability, and normative beliefs about aggression, undergraduates (N = 303) saw a violent film clip and a sad or a funny comparison clip. Skin conductance level (SCL) was measured continuously, and ratings of anxious and pleasant arousal were obtained after each clip. Following the clips, participants completed a lexical decision task to measure accessibility of aggressive cognitions and a competitive reaction time task to measure aggressive behavior. Habitual media violence exposure correlated negatively with SCL during violent clips and positively with pleasant arousal, response times for aggressive words, and trait aggression, but it was unrelated to anxious arousal and aggressive responding during the reaction time task. In path analyses controlling for trait aggression, normative beliefs, and trait arousability, habitual media violence exposure predicted faster accessibility of aggressive cognitions, partly mediated by higher pleasant arousal. Unprovoked aggression during the reaction time task was predicted by lower anxious arousal. Neither habitual media violence usage nor anxious or pleasant arousal predicted provoked aggression during the laboratory task, and SCL was unrelated to aggressive cognitions and behavior. No relations were found between habitual media violence viewing and arousal in response to the sad and funny film clips, and arousal in response to the sad and funny clips did not predict aggressive cognitions or aggressive behavior on the laboratory task. This suggests that the observed desensitization effects are specific to violent content. PMID:21186935

The current study investigates the relationship between involuntary hospitalization, severity of psychopathology, and aggression. Adult psychiatric inpatients hospitalized from August, 2012 to January, 2013 were evaluated via the Brief Psychiatric Rating Scale (BPRS) and the Overt Aggression Scale (OAS). Individuals were compared regarding voluntariness of hospitalization. Of the 137 hospitalizations in the period, 71 were involuntary (INV). The variables associated with involuntariness were being brought to hospital by ambulance or police, and aggression in the first 24 h of admission. Risk of suicide at admission, and having personal income were associated with voluntariness. The dimensions of the BPRS associated with involuntary hospitalization were activation, resistance, and positive symptoms. Involuntary psychiatric hospitalization was associated with agitation, psychosis and aggression. The data support the indication of involuntary hospitalization for treatment of patients with severe mental illness. Copyright © 2018. Published by Elsevier B.V.

Maternal Depression and Childhood Aggression: Literature Review

Introduction Childbearing depression (CBD) and childhood aggression are serious and international problems that encumber public health. Although maternal depression has received much attention in the literature in the last three decades, clinically it remains under-diagnosed and under-treated, especially during pregnancy. As a result, many mothers and families are left to suffer its long-lasting physical and psychosocial effects. This article's aim is to review the current literature on whether CBD increases the likelihood of childhood aggression in children ages six years and younger. Methods Using keywords, an electronic search was performed using Cumulative Index of Nursing and Allied Health, PsycINFO, and PubMed databases. Search limits included the following: 2000-2010, English, peer-review, human, All Child: 0-18. From more than 2,000 search results, 13 articles were reviewed based on relevance to paper's inquiry and sample size greater than 50. Results In all, the articles agreed that depression in women increases the likelihood of early childhood aggression by causing negative parenting behaviors. However, this finding is tempered by a number of weaknesses in the quality of articles reviewed and by the complexity of the topic. Conclusion More research is needed to determine the etiology and interplay of mediating factors between CBD and childhood aggression. This could inform the study and implementation of effective and early prevention, screening, and treatment measures and programs for maternal depression and childhood aggression. PMID:22739482

Aggressive behaviors are disabling, treatment refractory, and sometimes lethal symptoms of several neuropsychiatric disorders. However, currently available treatments for patients are inadequate, and the underlying genetics and neurobiology of aggression is only beginning to be elucidated. Inbred mouse strains are useful for identifying genomic regions, and ultimately the relevant gene variants (alleles) in these regions, that affect mammalian aggressive behaviors, which, in turn, may help to identify neurobiological pathways that mediate aggression. The BALB/cJ inbred mouse strain exhibits relatively high levels of intermale aggressive behaviors and shows multiple brain and behavioral phenotypes relevant to neuropsychiatric syndromes associated with aggression. The A/J strain shows very low levels of aggression. We hypothesized that a cross between BALB/cJ and A/J inbred strains would reveal genomic loci that influence the tendency to initiate intermale aggressive behavior. To identify such loci, we conducted a genomewide scan in an F2 population of 660 male mice bred from BALB/cJ and A/J inbred mouse strains. Three significant loci on chromosomes 5, 10 and 15 that influence aggression were identified. The chromosome 5 and 15 loci are completely novel, and the chromosome 10 locus overlaps an aggression locus mapped in our previous study that used NZB/B1NJ and A/J as progenitor strains. Haplotype analysis of BALB/cJ, NZB/B1NJ and A/J strains showed three positional candidate genes in the chromosome 10 locus. Future studies involving fine genetic mapping of these loci as well as additional candidate gene analysis may lead to an improved biological understanding of mammalian aggressive behaviors. © 2010 The Authors.

Building the case for a novel teleost model of non-breeding aggression and its neuroendocrine control.

In vertebrates, aggression has been traditionally associated with high levels of circulating androgens in breeding males. Nevertheless, the centrality of androgens as primary modulators of aggression is being reconsidered in at least in two particular cases: (1) territorial aggression outside the breeding season, and (2) aggression by females. We are developing the weakly electric fish, Gymnotus omarorum, as a novel, advantageous model system to address these two alternative forms of aggression. This species displays a short, escalated contest, after which a clear hierarchical status emerges. Subordination of individuals involves three sequential decisions: interruptions of their electric discharges, retreats, and chirps. These decisions are influenced by both size asymmetry between contenders and aggression levels of dominants. Both females and males are aggressive, and do not differ in fighting ability nor in the value placed on the resource. Aggression is completely independent of gonadal hormones: dominance status is unrelated to circulating androgen and estrogen levels, and gonadectomy in males does not affect aggression. Nevertheless, estrogenic pathways participate in the modulation of this non-breeding aggression. Our results parallel those put forth in other taxa, heightening the value of G. omarorum as a model to identify commonalities in neuroendrocrine strategies of vertebrate aggression control.

Data from clinical files of 30 male and 30 female patients across three forensic acute units for the first 60 days of hospitalisation were collected. Risk for imminent aggression as measured by the Dynamic Appraisal of Situational Aggression, documented nursing interventions following each assessment, and acts of aggression within the 24-hours following assessment were collected. Generalised estimating equations were used to investigate whether intervention strategies were associated with reduction in aggression. When a Dynamic Appraisal of Situational Aggression assessment was completed, nurses intervened more frequently compared to days when no Dynamic Appraisal of Situational Aggression assessment was completed. Higher Dynamic Appraisal of Situational Aggression assessments were associated with a greater number of interventions. The percentage of interventions selected for males differed from females; males received more pro re nata medication and observation, and females received more limit setting, one-to-one nursing and reassurance. Pro re nata medication was the most commonly documented intervention (35.9%) in this study. Pro re nata medication, limit setting and reassurance were associated with an increased likelihood of aggression in some risk bands. Structured risk assessment prompts intervention, and higher risk ratings result in more interventions. Patient gender influences the type of interventions. Some interventions are associated with

When Violence Pays: A Cost-Benefit Analysis of Aggressive Behavior in Animals and Humans

2013-01-01

An optimization analysis of human behavior from a comparative perspective can improve our understanding of the adaptiveness of human nature. Intra-specific competition for resources provides the main selective pressure for the evolution of violent aggression toward conspecifics, and variation in the fitness benefits and costs of aggression can account for inter-specific and inter-individual differences in aggressiveness. When aggression reflects competition for resources, its benefits vary in relation to the characteristics of the resources (their intrinsic value, abundance, spatial distribution, and controllability) while its costs vary in relation to the characteristics of organisms and how they fight (which, in turn, affects the extent to which aggression entails risk of physical injury or death, energetic depletion, exposure to predation, psychological and physiological stress, or damage to social relationships). Humans are a highly aggressive species in comparison to other animals, probably as a result of an unusually high benefit-to-cost ratio for intra-specific aggression. This conclusion is supported by frequent and widespread occurrence of male-male coalitionary killing and by male-female sexual coercion. Sex differences in violent aggression in humans and other species probably evolved by sexual selection and reflect different optimal competitive strategies for males and females. PMID:23864299

Effects of viewing relational aggression on television on aggressive behavior in adolescents: A three-year longitudinal study.

PubMed

Coyne, Sarah M

2016-02-01

Most researchers on media and aggression have examined the behavioral effects of viewing physical aggression in the media. Conversely, in the current study, I examined longitudinal associations between viewing relational aggression on TV and subsequent aggressive behavior. Participants included 467 adolescents who completed a number of different questionnaires involving media and aggression at 3 different time points. Results revealed that viewing relational aggression on TV was longitudinally associated with future relational aggression. However, early levels of relational aggression did not predict future exposure to televised relational aggression. Conversely, there was a bidirectional relationship between TV violence and physical aggression over time. No longitudinal evidence was found for a general effect of viewing TV, as all significant media effects were specific to the type of aggression viewed. These results support the general aggression model and suggest that viewing relational aggression in the media can have a long-term effect on aggressive behavior during adolescence.

Treatment-resistant Schizophrenia: Evidence-based Strategies

PubMed Central

Englisch, Susanne; Zink, Mathias

2012-01-01

Treatment-resistant symptoms complicate the clinical course of schizophrenia, and a large proportion of patients do not reach functional recovery. In consequence, polypharmacy is frequently used in treatment-refractory cases, addressing psychotic positive, negative and cognitive symptoms, treatment-emergent side effects caused by antipsychotics and comorbid depressive or obsessive-compulsive symptoms. To a large extent, such strategies are not covered by pharmacological guidelines which strongly suggest antipsychotic monotherapy. Add-on strategies comprise combinations of several antipsychotic agents and augmentations with mood stabilizers; moreover, antidepressants and experimental substances are applied. Based on the accumulated evidence of clinical trials and meta-analyses, combinations of clozapine with certain second-generation antipsychotic agents and the augmentation of antipsychotics with antidepressants seem recommendable, while the augmentation with mood stabilizers cannot be considered superior to placebo. Forthcoming investigations will have to focus on innovative pharmacological agents, the clinical spectrum of cognitive deficits and the implementation of cognitive behavioral therapy. PMID:22654380

Osteogenesis imperfecta in childhood: treatment strategies.

PubMed

Engelbert, R H; Pruijs, H E; Beemer, F A; Helders, P J

1998-12-01

Osteogenesis imperfecta (OI) is a skeletal disorder of remarkable clinical variability characterized by bone fragility, osteopenia, variable degrees of short stature, and progressive skeletal deformities. Additional clinical manifestations such as blue sclerae, dentinogenesis imperfecta, joint laxity, and maturity onset deafness are described in the literature. OI occurs in about 1 in 20,000 births and is caused by quantitative and qualitative defects in the synthesis of collagen I. Depending on the severity of the disease, a large impact on motor development, range of joint motion, muscle strength, and functional ability may occur. Treatment strategies should primarily focus on the improvement of functional ability and the adoption of compensatory strategies, rather than merely improving range of joint motion and muscle strength. Surgical treatment of the extremities may be indicated to stabilize the long bones to optimize functional ability and walking capacity. Surgical treatment of the spine may be indicated in patients with progressive spinal deformity and in those with symptomatic basilar impression.

Systemic diseases and their treatment influence aggressive posterior retinopathy of prematurity. A premature infant with aggressive posterior retinopathy of prematurity underwent laser treatment with a favourable outcome. She was started on oral sidenafil citrate for pulmonary hypertension. Ten days later she developed neovascularization within the lasered retina. Considering the possible role of sildenafil in this unusual development, the drug was withdrawn resulting in regression of the neovascularization. The clinician should be aware of this retinal adverse effect of sildanefil in neonates with aggressive posterior retinopathy of prematurity.

The General Aggression Model.

PubMed

Allen, Johnie J; Anderson, Craig A; Bushman, Brad J

2018-02-01

The General Aggression Model (GAM) is a comprehensive, integrative, framework for understanding aggression. It considers the role of social, cognitive, personality, developmental, and biological factors on aggression. Proximate processes of GAM detail how person and situation factors influence cognitions, feelings, and arousal, which in turn affect appraisal and decision processes, which in turn influence aggressive or nonaggressive behavioral outcomes. Each cycle of the proximate processes serves as a learning trial that affects the development and accessibility of aggressive knowledge structures. Distal processes of GAM detail how biological and persistent environmental factors can influence personality through changes in knowledge structures. GAM has been applied to understand aggression in many contexts including media violence effects, domestic violence, intergroup violence, temperature effects, pain effects, and the effects of global climate change.

Anger is an empirically established precipitant to aggressive responding toward intimate partners. The current investigation examined the effects of anger, as experienced by both partners, as well as gender and previous aggression, on in vivo intimate partner aggression using a prospective daily diary methodology. Participants (N = 118 couples) individually provided 56 consecutive, daily reports of affective experience and partner aggression. Multilevel models were estimated using the Actor Partner Interdependence Model framework to analyze the daily associations between anger and partner aggression perpetration among male and female participants as moderated by aggression history. Results revealed that both Actor and Partner anger were generally associated with subsequently reported daily conflict. Further, increases in daily Partner anger were associated with corresponding increases in partner aggression among females who reported high anger and males, regardless of their own anger experience. Increases in Actor anger were associated with increases in daily partner aggression only among previously aggressive females. Previously aggressive males and females consistently reported greater perpetration than their nonaggressive counterparts on days of high Actor anger experience. Results emphasize the importance of both Actor and Partner factors in partner aggression and suggest that female anger may be a stronger predictor of both female-to-male and male-to-female partner aggression than male anger, when measured at the daily level.

Bullying in schools is a major health concern throughout the world, contributing to poor educational and mental health outcomes. School nurses are well placed to facilitate the implementation and evaluation of bullying prevention strategies. To evaluate the effect of such strategies, it is necessary to measure children's behavior over time. This scoping review of instruments that measure the self-report of aggressive behavior and bullying by children will inform the evaluation of bullying interventions. This review aimed to identify validated instruments that measure aggression and bullying among preadolescent children (age 8-12). The review was part of a larger study that sought to differentiate bullying from aggressive behavior by measuring the self-report of power imbalance between the aggressor and the child being bullied. The measurement of power imbalance was therefore a key aspect of the scoping review.

Trait aggressiveness modulates neurophysiological correlates of laboratory-induced reactive aggression in humans.

Reactive aggression following provocation is a frequent form of human social behavior. The neural basis of reactive aggression, especially its control, remains poorly understood, however. We conducted an event-related potential (ERP) study using a competitive reaction time task that elicits aggression through provocation. Participants were selected from a larger sample because of extreme scores in trait aggressiveness, yielding high and low trait aggressive groups. As each trial in the task is separated into a decision phase, during which the punishment level for the opponent is set, and an outcome phase, during which the punishment is applied or received, we were able to disentangle provocation-related and evaluation-related modulations of the ERPs during the aggressive interaction. Specifically, we observed an enhanced frontal negativity during the decision phase under high provocation that was positively correlated with the participants' ability to refrain from retaliation. This held true for high trait aggressive participants only, pointing to a higher need for inhibitory and control processes in these people when provoked. During the outcome phase, we detected a mediofrontal negativity in loss compared to win trials, resembling previous ERP findings to negative feedback stimuli, which have been linked to the evaluation of an outcome's valence. This mediofrontal negativity was differentially pronounced in aggressive and nonaggressive participants: Nonaggressive participants showed only a slightly smaller mediofrontal negativity in win than in loss trials, suggesting that for them punishing the opponent had a similar negative valence as being punished.

Treatment of relapse and primary progression in aggressive lymphoma remains unsatisfactory; outcome is still poor. Better treatment strategies are much needed for this patient population. The R1 study is a prospective multi-center phase I/II study evaluating a dose finding approach with a triple transplant regimen in four BEAM dose levels in patients with relapsed aggressive non-Hodgkin lymphoma. The aim of the study was to determine feasibility, toxicity, and remission rate. In a total of 39 patients (pts.) enrolled in the study, 24 pts. were evaluated in the following analysis. Twenty pts. had aggressive B cell lymphoma, and two pts. had T cell lymphoma. All evaluated patients responded to DexaBEAM with a sufficient stem cell harvest. The phase I/II study was started with BEAM dose level II. Four patients were treated at dose level II, and 20 pts. were treated at dose level III. Due to the early termination of the study, dose levels I and IV were never administered. Sixteen pts. completed therapy according to protocol, and eight pts. (33.3 %) stopped treatment early. Infections (27 %) and stomatitis (13 %) were the most frequent grade III/IV non-hematologic toxicities. Thirteen percent of patients presented with severe grade III/IV lung toxicity during modified BEAM (m-BEAM). Fourteen pts. achieved a complete response (CR), one pt. achieved no change (NC), six pts. had progressive disease (PD), and two pts. died; for one pt., outcome is not known. One-year and 3-year event-free survival (EFS) was 38 and 33 %, respectively. Overall survival (OS) after 1 and 3 years was 50 and 38 %. In conclusion, dose escalation of standard BEAM is not feasible due to toxicity.

Feline aggression towards people has a smaller incidence than canine aggression, but also represents an important public health problem. The aim of this work was to analyse feline aggression reported towards people, to estimate its incidence and to assess the risk factors involved. The information was obtained from the Public Health Centres in the Valencian Region (Spain). A total of 936 acts of feline aggression were analysed. Cats inflicted 8% of all animal bites reported. The annual average was 6.36 feline aggression incidents per 100,000 people. Most aggressive incidents occurred during the summer months. Children (0-14 years old) and women were more likely to be bitten. Wounds were mainly punctures, single, and mild, and were located mostly on the hands. In children, the head and neck areas were affected much more than in adults. The cats involved in incidents were mostly Siamese, female and owned; these cats mainly attacked their owners. Most occurrences were a defensive response by the cat.

When do normative beliefs about aggression predict aggressive behavior? An application of I3 theory.

PubMed

Li, Jian-Bin; Nie, Yan-Gang; Boardley, Ian D; Dou, Kai; Situ, Qiao-Min

2015-01-01

I(3) theory assumes that aggressive behavior is dependent on three orthogonal processes (i.e., Instigator, Impellance, and Inhibition). Previous studies showed that Impellance (trait aggressiveness, retaliation tendencies) better predicted aggression when Instigator was strong and Inhibition was weak. In the current study, we predicted that another Impellance (i.e., normative beliefs about aggression) might predict aggression when Instigator was absent and Inhibition was high (i.e., the perfect calm proposition). In two experiments, participants first completed the normative beliefs about aggression questionnaire. Two weeks later, participants' self-control resources were manipulated either using the Stroop task (study 1, N = 148) or through an "e-crossing" task (study 2, N = 180). Afterwards, with or without being provoked, participants played a game with an ostensible partner where they had a chance to aggress against them. Study 1 found that normative beliefs about aggression negatively and significantly predicted aggressive behavior only when provocation was absent and self-control resources were not depleted. In Study 2, normative beliefs about aggression negatively predicted aggressive behavior at marginal significance level only in the "no-provocation and no-depletion" condition. In conclusion, the current study provides partial support for the perfect calm proposition and I(3) theory. © 2015 Wiley Periodicals, Inc.

Adolescent bystanders' perspectives of aggression in the online versus school environments.

PubMed

Patterson, Lisa J; Allan, Alfred; Cross, Donna

2016-06-01

Researchers' understanding of bystanders' perspectives in the cyber-environment fails to take young people's perceptions into account and remains imperfect. Interventions encouraging adolescents to help targets of cyber-aggression are therefore typically based upon traditional school-based aggression research. Twenty-four in-depth interviews with Australian 13-16 year-olds revealed two themes that reflect how young bystanders perceive differences between aggression online and at school. The physical presence theme suggests that young bystanders struggle to determine online intentions in the absence of body language, leading to hesitancy in reactions and furthermore make it easier for them to ignore online transgressions and avoid becoming involved. The authority theme indicates young bystanders perceive that, compared to the school environment, the online environment lacks clearly established rules, authority figures and formal reporting mechanisms. These differences indicate that unique strategies should be developed to encourage young bystanders to intervene in cyber-aggression situations.

This study sought to determine if an aggressive, focused low-density lipoprotein cholesterol (LDL-C)-lowering strategy was superior to usual care for coronary heart disease (CHD) patients enrolled in health maintenance organization or Veterans Administration settings. Statin therapy benefits are well established. No prospective, randomized studies have tested strategies to optimize these benefits in a "real-world" setting. A total of 2,442 CHD patients with hyperlipidemia were randomized to either an aggressive treatment arm using atorvastatin or usual care and followed for 51.5 months on average. Atorvastatin-group patients were titrated to LDL-C goals of <80 mg/dl (2.1 mmol/l) or a maximum atorvastatin dose of 80 mg/day. Usual-care patients received any treatment deemed appropriate by their regular physicians. End point assessments were complete in 958 atorvastatin-group and 941 usual-care patients. Partial assessments occurred in 259 patients in the atorvastatin group and 284 patients in the usual care group who did not complete four years of study participation because of adverse events, withdrawn consent, or follow-up loss. The primary efficacy parameter was time to first cardiovascular event. A total of 289 (23.7%) patients in the atorvastatin group compared with 333 (27.7%) patients in the usual care group experienced a primary outcome (hazard ratio, 0.83; 95% confidence interval 0.71 to 0.97, p = 0.02). This reduction in morbidity was largely due to fewer non-fatal myocardial infarctions (4.3% vs. 7.7%, p = 0.0002). Levels of LDL-C were reduced more (34.3% vs. 23.3%, p < 0.0001) and National Cholesterol Education Program goals (LDL-C <100 mg/dl) more likely met at end-of-study visits (72.4% vs. 40.0%) in patients receiving atorvastatin compared with those receiving usual care. An aggressive, focused statin therapy management strategy outperformed usual care in health maintenance organization and Veterans Administration clinic patients with CHD.

Aggressive Marital Conflict, Maternal Harsh Punishment, and Child Aggressive-Disruptive Behavior: Evidence for Direct and Mediated Relations

2009-01-01

Direct associations between aggressive marital conflict and child aggressive-disruptive behavior at home and school were explored in this cross-sectional study of 360 kindergarten children. In addition, mediated pathways linking aggressive marital conflict to maternal harsh punishment to child aggressive-disruptive behavior were examined. Moderation analyses explored how the overall frequency of marital disagreement might buffer or exacerbate the impact of aggressive marital conflict on maternal harsh punishment and child aggressive-disruptive behavior. Hierarchical regressions revealed direct pathways linking aggressive marital conflict to child aggressive-disruptive behavior at home and school and a partially mediated pathway linking aggressive marital conflict to child aggressive-disruptive behavior at home. Further analyses revealed that rates of marital disagreement moderated the association between aggressive marital conflict and child aggressive-disruptive behavior at home, with an attenuated association at high rates of marital disagreement as compared with low rates of marital disagreement.

The impact of classroom aggression on the development of aggressive behavior problems in children

Prior research suggests that exposure to elementary classrooms characterized by high levels of student aggression may contribute to the development of child aggressive behavior problems. To explore this process in more detail, this study followed a longitudinal sample of 4,907 children and examined demographic factors associated with exposure to high-aggression classrooms, including school context factors (school size, student poverty levels, and rural vs. urban location) and child ethnicity (African American, European American). The developmental impact of different temporal patterns of exposure (e.g., primacy, recency, chronicity) to high-aggression classrooms was evaluated on child aggression. Analyses revealed that African American children attending large, urban schools that served socioeconomically disadvantaged students were more likely than other students to be exposed to high-aggressive classroom contexts. Hierarchical regressions demonstrated cumulative effects for temporal exposure, whereby children with multiple years of exposure showed higher levels of aggressive behavior after 3 years than children with primacy, less recent, and less chronic exposure, controlling for initial levels of aggression. Implications are discussed for developmental research and preventive interventions. PMID:16600064

The research goals were to use the constructs of harm and intent to quantify the severity of aggression in the real-world setting of the bar/club, to describe the range of aggressive behaviors and their relationship to harm and intent, and to examine gender differences in the form and severity of aggression. Systematic observations were conducted by trained observers on 1,334 nights in 118 bars/clubs. Observers documented a range of aggressive acts by 1,754 patrons in 1,052 incidents, with many forms of aggression occurring at more than one harm and intent level. Women used different forms of aggression, inflicted less harm, and were more likely to have defensive intent compared with men. Implications of the findings for research and measurement of aggression and applications to preventing aggression and violence are discussed.

Our objective is to describe a case of hypothermic politrauma management in our country. We report the case of a 29-year-old male who was a beating victim and fell off from 4 meters, and was afterwards found after an unknown time interval. The patient came to our DEA in cardiac arrest and underwent to a aggressive and prolonged resuscitation which included sternotomy and extracorporeal circulation. The patient was discharged in 40th postoperative day without neurologic complications and complete recovery. Even without a dedicated protocol for the hypothermic politrauma the correct multidisciplinary approach lead to the complete recovery of the patient. In literature many papers describe the aggressive resuscitation of hypothermic patients underlining that the politrauma management must be multidisciplinar. We want to underline the importance of the "Damage control strategy" in a politrauma team in the major hospitals in our country.

Although there have been hundreds of studies on media violence, few have focused on literature, with none examining novels. Accordingly, the aim of the current study was to examine whether reading physical and relational aggression in books was associated with aggressive behavior in adolescents. Participants consisted of 223 adolescents who completed a variety of measures detailing their media use and aggressive behavior. A non-recursive structural equation model revealed that reading aggression in books was positively associated with aggressive behavior, even after controlling for exposure to aggression in other forms of media. Associations were only found for congruent forms of aggression. Implications regarding books as a form of media are discussed. © 2013 Wiley Periodicals, Inc.

Identifying key factors associated with aggression on acute inpatient psychiatric wards.

Bowers, Len; Allan, Teresa; Simpson, Alan; Jones, Julia; Van Der Merwe, Marie; Jeffery, Debra

2009-04-01

Aggressive behaviour is a critical issue for modern acute psychiatric services, not just because of the adverse impact it has on patients and staff, but also because it puts a financial strain on service providers. The aim of this study was to assess the relationship of patient violence to other variables: patient characteristics, features of the service and physical environment, patient routines, staff factors, the use of containment methods, and other patient behaviours. A multivariate cross sectional design was utilised. Data were collected for a six month period on 136 acute psychiatric wards in 26 NHS Trusts in England. Multilevel modelling was conducted to ascertain those factors most strongly associated with verbal aggression, aggression toward objects, and physical aggression against others. High levels of aggression were associated with a high proportion of patients formally detained under mental health legislation, high patient turnover, alcohol use by patients, ward doors being locked, and higher staffing numbers (especially qualified nurses). The findings suggest that the imposition of restrictions on patients exacerbates the problem of violence, and that alcohol management strategies may be a productive intervention. Insufficient evidence is available to draw conclusions about the nature of the link between staffing numbers and violence.

2016-06-30

This study assessed the association between indirectly measured behavioural approach- and avoidance-related tendencies on the one hand, and reactive versus proactive aggression on the other hand. Reactive aggression (i.e. the impulsive, anger-driven aggression expressed in response to threatening stimuli) was differentiated from proactive aggression (i.e. the more controlled aggression motivated towards obtaining specific goals). A mixed sample of 118 patients and healthy controls filled out a self-report measure to assess their degree of reactive and proactive aggression, and then performed an Approach Avoidance Task in which they were asked to pull or push a joystick in response to a format-feature of a series of pictures, irrespective of their contents. The pictorial stimuli used in this task included attack-related scenes and angry faces, along with neutral, positive and negative control stimuli. The results were controlled for the level of personality disorder pathology, gender, and age. The findings indicated that reactive but not proactive aggression was related to the relative behavioural tendency to approach attack-related scenes, along with positive stimuli. These findings reflect the hyper-reactivity of the approach-related reward system in reactive aggression, and further our knowledge into the distinct correlates and precursors of reactive and proactive aggression.

2006-10-01

To compare patients with traumatic brain injury (TBI) with controls on sub-types of aggression and explore the role of social desirability. Quasi-experimental, matched-participants design. Sixty-nine participants were included in the study. The sample comprised a TBI group (n = 24), a spinal cord injury (SCI) group (n = 21) and an uninjured (UI) group of matched healthy volunteers (n = 24). Participants were given self-report measures of aggression, social desirability and impulsivity. Sixty-one independent 'other-raters' were nominated, who rated participant pre-morbid and post-morbid aggression. Using standardized norms, 25-39% of participants with TBI were classified as high average-very high on anger and 35-38% as high average-very high on verbal aggression. Other-raters rated participants with TBI as significantly higher on verbal aggression than SCI and UI participants. There were no differences between the groups on physical aggression. The TBI group also had higher levels of impulsivity than SCI and UI groups. Social desirability was a highly significant predictor of self-reported aggression for the entire sample. Impulsive verbal aggression and anger are the principal aggressive traits after brain injury. Physical aggression may present in extreme cases after TBI, but appears less prominent overall in this population. Social desirability, previously overlooked in research examining TBI aggression, emerged as an influential variable that should be considered in future TBI research.

Milnacipran affects mouse impulsive, aggressive, and depressive-like behaviors in a distinct dose-dependent manner.

Serotonin/noradrenaline reuptake inhibitors (SNRIs) are widely used for the treatment for major depressive disorder, but these drugs induce several side effects including increased aggression and impulsivity, which are risk factors for substance abuse, criminal involvement, and suicide. To address this issue, milnacipran (0, 3, 10, or 30 mg/kg), an SNRI and antidepressant, was intraperitoneally administered to mice prior to the 3-choice serial reaction time task, resident-intruder test, and forced swimming test to measure impulsive, aggressive, and depressive-like behaviors, respectively. A milnacipran dose of 10 mg/kg suppressed all behaviors, which was accompanied by increased dopamine and serotonin levels in the medial prefrontal cortex (mPFC) but not in the nucleus accumbens (NAc). Although the most effective dose for depressive-like behavior was 30 mg/kg, the highest dose increased aggressive behavior and unaffected impulsive behavior. Increased dopamine levels in the NAc could be responsible for the effects. In addition, the mice basal impulsivity was negatively correlated with the latency to the first agonistic behavior. Thus, the optimal dose range of milnacipran is narrower than previously thought. Finding drugs that increase serotonin and dopamine levels in the mPFC without affecting dopamine levels in the NAc is a potential strategy for developing novel antidepressants.

Researching the correlates of men's sexually aggressive behavior (i.e., verbal coercion and rape) is critical to both understanding and preventing sexual aggression. This study examined 120 men who completed an anonymous online questionnaire. The study aimed to determine the relative importance of two potential correlates of men's self-reported use of sexual aggression: (a) perceptions that male peers use and support sexual aggression and (b) perceptions of punishment likelihood associated with sexual aggression. Results revealed that perceptions of male friends' acceptance of sexual aggression were strongly associated with individual men's reports of using verbal coercion and rape. Perceptions of punishment likelihood were negatively correlated with verbal coercion but not with rape through intoxication and force. Implications for sexual aggression prevention are discussed.

To assess the prevalence of verbally and physically aggressive behaviors in dating relationships in a sample of Spanish adolescents. Cross-sectional self-report data were obtained with The Modified Conflict Tactics Scale (MCTS) from a representative sample of 2416 adolescents and young adults of both genders, between ages of 16 and 20 years. The results showed that a significantly higher percentage of women engaged in verbal aggression (95.3% vs. 92.8%), whereas the males engaged in more severe physical aggression (4.6% vs. 2.0%) and produced worse consequences for their female partners' health (especially slight cuts/slight bruises, broken nose, black eye, broken bone and requiring medical treatment/hospitalization). Justification for aggression also revealed differential results. Whereas women said they attacked their partners while under the influence of emotional states of intense anger (22.4% vs. 13.9%), the males said they did so in response to aggression received (13.0% vs. 6.6%). The analysis of the group differences as a function of age showed that verbal aggression was very high and was not different across the age groups. In contrast, physical aggression decreased significantly across the age groups, but health consequences became more severe with age (e.g., broken nose, black eye, broken bone, went from 1% at 16 years to 4.5% at 20 years of age). These differential tendencies of aggression typology for men and women help clinicians to develop preventive interventions for every age, with the aim of diminishing their continuity in future relationships.

The relative lengths of the 2(nd) and 4(th) digits (2D:4D) is a negative biomarker for prenatal testosterone, and low 2D:4D may be associated with aggression. However, the evidence for a 2D:4D-aggression association is mixed. Here we test the hypothesis that 2D:4D is robustly linked to aggression in "challenge" situations in which testosterone is increased. Participants were exposed to an aggressive video and a control video. Aggression was measured after each video and salivary free testosterone levels before and after each video. Compared to the control video, the aggressive video was associated with raised aggression responses and a marginally significant increase in testosterone. Left 2D:4D was negatively correlated with aggression after the aggressive video and the strength of the correlation was higher in those participants who showed the greatest increases in testosterone. Left 2D:4D was also negatively correlated to the difference between aggression scores in the aggressive and control conditions. The control video did not influence testosterone concentrations and there were no associations between 2D:4D and aggression. We conclude that 2D:4D moderates the impact of an aggressive stimulus on aggression, such that an increase in testosterone resulting from a "challenge" is associated with a negative correlation between 2D:4D and aggression.

Treatment Strategy for Gastric Mucosa-Associated Lymphoid Tissue Lymphoma.

Recent trends and current knowledge on the diagnosis and treatment strategy for gastric mucosa-associated lymphoid tissue (MALT) lymphoma are reviewed. Helicobacter pylori infection plays the causative role in the pathogenesis, and H pylori eradication is the first-line treatment of this disease, which leads to complete remission in 60% to 90% of cases. A Japanese multicenter study confirmed that the long-term outcome of gastric MALT lymphoma after H pylori eradication is excellent. Treatment strategies for patients not responding to H pylori eradication including "watch and wait" strategy, radiotherapy, chemotherapy, rituximab immunotherapy, and combination of these should be tailored in consideration of the disease extent in each patient.

Aggression can alter infectious disease dynamics through two, non-exclusive mechanisms: 1) increasing direct contact among hosts and 2) altering hosts' physiological response to pathogens. Here we examined the latter mechanism in a social songbird by manipulating intraspecific aggression in the absence of direct physical contact. We asked whether the extent of aggression an individual experiences alters glucocorticoid levels, androgen levels, and individual responses to infection in an ecologically relevant disease model: house finches (Haemorhous mexicanus) infected with Mycoplasma gallisepticum (MG). Wild-caught male finches were housed in one of three settings, designed to produce increasing levels of aggression: 1) alone, with no neighbor ("no neighbor"), 2) next to a sham-implanted stimulus male ("sham neighbor"), or 3) next to a testosterone-implanted stimulus male ("testosterone neighbor"). Following one week of social treatment, focal males were experimentally infected with MG, which causes severe conjunctivitis and induces sickness behaviors such as lethargy and anorexia. While social treatment increased aggression as predicted, there were no differences among groups in baseline corticosterone levels, total circulating androgens, or responses to infection. Across all focal individuals regardless of social treatment, pre-infection baseline corticosterone levels were negatively associated with the severity of conjunctivitis and sickness behaviors, suggesting that corticosterone may dampen inflammatory responses in this host-pathogen system. However, because corticosterone levels differed based upon population of origin, caution must be taken in interpreting this result. Taken together, these results suggest that in captivity, although aggression does not alter individual responses to MG, corticosterone may play a role in this disease. © 2014 Wiley Periodicals, Inc.

Stepped-care has been recommended in the alcohol and other drug field and adopted in a number of service settings, but few research projects have examined this approach. This article aims to describe a pilot trial of stepped-care methods in the treatment of methamphetamine use and depression comorbidity. An adaptive treatment strategy was developed based on recommendations for stepped-care among methamphetamine users, and incorporating cognitive behaviour therapy/motivational intervention for methamphetamine use and depression. The adaptive treatment strategy was compared with a fixed treatment, comprising an extended integrated cognitive behaviour therapy/motivational intervention treatment. Eighteen participants across two study sites were involved in the trial, and were current users of methamphetamines (at least once weekly) exhibiting at least moderate symptoms of depression (score of 17 or greater on the Beck Depression Inventory II). Treatment delivered via the adaptive treatment (stepped-care) model was associated with improvement in depression and methamphetamine use, however, was not associated with more efficient delivery of psychological treatment to this population relative to the comparison treatment. This pilot trial attests to the potential for adaptive treatment strategies to increase the evidence base for stepped-care approaches within the alcohol and other drug field. However, in order for stepped-care treatment in this trial to be delivered efficiently, specific training in the delivery and philosophy of the model is required.

The heterogeneity of violent behavior is often overlooked in risk assessment despite its importance in the management and treatment of psychiatric and forensic patients. In this study, items from the Personality Assessment Inventory (PAI) were first evaluated and rated by experts in terms of how well they assessed personality features associated with reactive and instrumental aggression. Exploratory principal component analyses (PCA) were then conducted on select items using a sample of psychiatric and forensic inpatients (n = 479) to examine the latent structure and construct validity of these reactive and instrumental aggression factors. Finally, a confirmatory factor analysis (CFA) was conducted on a separate sample of psychiatric inpatients (n = 503) to evaluate whether these factors yielded acceptable model fit. Overall, the exploratory and confirmatory analyses supported the existence of two latent PAI factor structures, which delineate personality traits related to reactive and instrumental aggression.

In a cross-sectional sample of African-American 2nd-4th grade students (N = 681), we examine the moderating effects of classroom overt and relational aggression norms on peers' social acceptance of classmates who exhibit overt and relational aggression in urban schools. Extending theory and research on classroom norms, we integrate social network data to adjust aggression norms based on children's direct and indirect connections in the classroom. Results of multilevel models indicate that network-based classroom aggression norms moderated relations between children's aggressive behavior and their social preference. Specifically, children benefited socially when their form of aggressive behavior fit with what was normative in the classroom social context. The moderating effect of classroom aggression norms was stronger for the association between overt aggression and social preference than relational aggression and social preference. Relationally aggressive youth were socially preferred by peers regardless of the classroom norm, although this positive association was magnified in classrooms with higher levels of relational aggression. Future research focused on aggression norms within classroom social networks are discussed and implications for school prevention efforts are considered.

Aggressive fibromatoses are histologically benign fibrous neoplasms originating from musculoaponeurotic structures throughout the body. They are locally invasive and erode adjacent vital structures. The head and neck region constitutes 7-25% of all extra-abdominal cases. Here, we report the case of a patient with aggressive fibromatosis in the left side of the neck. While the tumor deeply invaded the scalene muscles, the lesion was successfully treated by surgery followed by radiotherapy. The patient has been disease free for the last 7 years following treatment. Due to its unusual location in the head and neck region, aggressive fibromatosis should be considered in the differential diagnosis of invading lesions of the neck.

Modern therapy for rheumatoid arthritis (RA) is based on knowledge of the severity of the natural history of the disease. RA patients are approached with early and aggressive treatment strategies, methotrexate as an anchor drug, biological targeted therapies in those with inadequate response to methotrexate, and “tight control,” aiming for remission and low disease activity according to quantitative monitoring. This chapter presents a rationale for current treatment strategies for RA with antirheumatic drugs, a review of published reports concerning treatments in clinical cohorts outside of clinical trials, and current treatments at 61 sites in 21 countries in the QUEST-RA database.

Violence and drug use are significant public health challenges that are strongly linked. It is known that alcohol plays a major role in the causation of unnatural deaths and that stimulants like cocaine and amphetamine are often implicated in aggressive acts or violence. However, a clear causal relationship between these substances and aggression, and more specifically a blood concentration threshold at which intoxicated aggression emerges is lacking. In case of a crime and subsequent law enforcement, knowledge about dose-response relationships could be of pivotal importance when evaluating the role of alcohol and drugs in aggressive offences. The present review aimed to determine whether there is a causal relation between intoxication with these psychoactive substances and aggression, and to define blood concentration thresholds above which these substances elicit aggression. Empirical articles published between 2013 and 2017 and review papers containing the predefined search strings were identified through searches in the PubMed and Embase databases and additional reference list searches. The complete search query yielded 1578 publications. Initially all articles were manually screened by title and abstract. Articles with irrelevant titles, given the selected search terms and review aims were discarded. Remaining articles were carefully studied and those that did not comply with the main objectives of this review were discarded. At the end of this process, 167 titles were found eligible for review. While placebo-controlled experimental studies clearly showed a causal link between alcohol and aggression, it is evident that such a link has not yet been established for cocaine and amphetamines. In case of alcohol, it is clear that there are various individual and contextual factors that may contribute to the occurrence of an aggressive act during intoxication. A clear threshold blood alcohol concentration has not been defined yet for alcohol, but a statistically

Existing literature exemplifies the relationship between alcohol and overt aggression, especially for adult males. Less clear is the relationship between alcohol and aggression among male and female college students, in particular, the nature of this aggression and the co-occurrence of drinking and aggression on the same day (temporal proximity). This study examines the chronic and temporal nature of males' and females' alcohol-related aggression among college students. Two hundred fourteen students completed a web-based 7-day event-level survey measuring alcohol consumption and perpetration of physical aggression, verbal aggression, anger, and relational aggression over 4 weeks, resulting in 4,256 observations (days). The global analysis revealed students who are heavy drinkers are more likely to perpetrate all four forms of aggression, whereas the event-level analysis revealed that specific forms of aggression are associated with drinking at the time, while other forms were not linked to drinking occasions. Cross-tabulation revealed males and females were more likely to use verbal and physical aggression when drinking. For females, drinking was also associated with relational aggression and anger. Despite often being overlooked in research on aggression during emerging adulthood, relational aggression was prevalent. Discrepancies between the global and temporal analysis revealed factors other than alcohol might explain the relationship between chronic alcohol consumption and specific forms of aggression. This is one of the first event-level studies to show the temporal relationship between alcohol and relational aggression. The distinctions in the current study, exemplifying the diversity of alcohol-related aggression, are critical for understanding aggressive behavior, potential gender differences, and for developing interventions. The temporal relationship between alcohol and aggression suggests health interventions should target drinking and aggression

Chronic enhancement of brain oxytocin levels causes enduring anti-aggressive and pro-social explorative behavioral effects in male rats.

Oxytocin (OXT) has been implicated in the regulation of social behaviors, including intermale offensive aggression. Recently, we showed that acute enhancement of brain OXT levels markedly suppressed offensive aggression and increased social exploration in resident rats confronted with an intruder in their home territory. Moreover, a different responsivity to the exogenous OXTergic manipulation was observed among individuals based on their baseline aggression. In this study we aimed at evaluating the behavioral response to chronically enhancing or attenuating central OXT levels, and at scrutinizing whether the trait-aggression moderates the treatment-induced behavioral changes. To this end, resident male wild-type Groningen rats were continuously (via osmotic minipumps) intracerebroventricularly infused with synthetic OXT or a selective OXT receptor (OXTR) antagonist for 7days. Changes in behavior were assessed performing a resident-intruder test before and at the end of the treatment period, as well as after 7days of withdrawal. Chronic infusion of OXT was found to selectively suppress aggression and enhance social exploration. Chronic blockage of OXTRs instead increased introductory aggressive behavior (i.e. lateral threat), yet without affecting the total duration of the aggression. The magnitude of the anti-aggressive changes correlated positively with the level of baseline aggression. Interestingly, OXT-induced behavioral changes persisted 7days after cessation of the treatment. In conclusion, these findings provide further evidence that enhanced functional activity of the central OXTergic system decreases social offensive aggression while it increases social explorative behavior. The data also indicate that chronically enhancing brain OXT levels may cause enduring anti-aggressive and pro-social explorative behavioral effects. Copyright © 2014 Elsevier Inc.
