Abstract
INTRODUCTION On psychiatric wards, aggressive behaviour displayed by patients is common and problematic. Understanding factors associated with the development of aggression offers possibilities for prevention and targeted interventions. This review discusses factors that contribute to the development of aggression on psychiatric wards. METHOD In Pubmed and Embase, a search was performed aimed at: prevalence data, ward characteristics, patient and staff factors that are associated with aggressive behaviour and from this search 146 studies were included. RESULTS The prevalence of aggressive behaviour on psychiatric wards varied (8-76%). Explanatory factors of aggressive behaviour were subdivided into patient, staff and ward factors. Patient risk factors were diagnosis of psychotic disorder or bipolar disorder, substance abuse, a history of aggression, younger age. Staff risk factors included male gender, unqualified or temporary staff, job strain, dissatisfaction with the job or management, burn-out and quality of the interaction between patients and staff. Staff protective factors were a good functioning team, good leadership and being involved in treatment decisions. Significant ward risk factors were a higher bed occupancy, busy places on the ward, walking rounds, an unsafe environment, a restrictive environment, lack of structure in the day, smoking and lack of privacy. CONCLUSION Despite a lack of prospective quantitative data, results did show that aggression arises from a combination of patient factors, staff factors and ward factors. Patient factors were studied most often, however, besides treatment, offering the least possibilities in prevention of aggression development. Future studies should focus more on the earlier stages of aggression such as agitation and on factors that are better suited for preventing aggression such as ward and staff factors. Management and clinicians could adapt staffing and ward in line with these results.

Abstract
Time-of-day is a crucial, yet often overlooked, biological variable in biomedical research. We examined the top 25 most cited papers in several domains of behavioral neuroscience to determine whether time-of-day information was reported. The majority of studies report behavioral testing conducted during the day, which does not coincide with the optimal time to perform the testing from an functional perspective of the animals being tested. The majority of animal models used in biomedical research are nocturnal rodents; thus, testing during the light phase (i.e. animals' rest period) may alter the results and introduce variability across studies. Time-of-day is rarely considered in analyses or reported in publications; the majority of publications fail to include temporal details when describing their experimental methods, and those few that report testing during the dark rarely report whether measures are in place to protect from exposure to extraneous light. We propose that failing to account for time-of-day may compromise replication of findings across behavioral studies and reduce their value when extrapolating results to diurnal humans.

Abstract
Optogenetics and chemogenetics are powerful tools, allowing the specific activation or inhibition of targeted neuronal subpopulations. Application of these techniques to sleep and circadian research has resulted in the unveiling of several neuronal populations that are involved in sleep-wake control, and allowed a comprehensive interrogation of the circuitry through which these nodes are coordinated to orchestrate the sleep-wake cycle. In this review, we discuss six recently described sleep-wake and circadian circuits that show promise as therapeutic targets for sleep medicine. The parafacial zone (PZ) and the ventral tegmental area (VTA) are potential druggable targets for the treatment of insomnia. The brainstem circuit underlying rapid eye movement sleep behavior disorder (RBD) offers new possibilities for treating RBD and neurodegenerative synucleinopathies, whereas the parabrachial nucleus, as a nexus linking arousal state control and breathing, is a promising target for developing treatments for sleep apnea. Therapies that act upon the hypothalamic circuitry underlying the circadian regulation of aggression or the photic regulation of arousal and mood pathway carry enormous potential for helping to reduce the socioeconomic burden of neuropsychiatric and neurodegenerative disorders on society. Intriguingly, the development of chemogenetics as a therapeutic strategy is now well underway and such an approach has the capacity to lead to more focused and less invasive therapies for treating sleep-wake disorders and related comorbidities.

Abstract
The central circadian clock, located in the suprachiasmatic nucleus of the mammalian hypothalamus (SCN), regulates daily behavioral rhythms including the temporal propensity for aggressive behavior. Such aggression propensity rhythms are regulated by a functional circuit from the SCN to neurons that drive attack behavior in the ventromedial hypothalamus (VMH), via a relay in the subparaventricular zone (SPZ). In addition to this pathway, the SCN also regulates sleep-wake and locomotor activity rhythms, via the SPZ, in a circuit to the dorsomedial hypothalamus (DMH), a structure that is also known to play a key role in autonomic function and the sympathetic "fight-or-flight" response (which prepares the body for action in stressful situations such as an agonistic encounter). While the autonomic nervous system is known to be under pronounced circadian control, it is less apparent how such autonomic rhythms and their underlying circuitry may support the temporal propensity for aggressive behavior. Additionally, it is unclear how circadian and autonomic dysfunction may contribute to aberrant social and emotional behavior, such as agitation and aggression. Here we review the literature concerning interactions between the circadian and autonomic systems and aggression, and we discuss the implications of these relationships for human neural and behavioral pathologies.

Abstract
“Sundowning” in dementia and Alzheimer’s disease is characterized by early evening agitation and aggression. While such periodicity suggests a circadian origin, whether the circadian clock directly regulates aggressive behavior is unknown. We demonstrate that a daily rhythm in aggression propensity in male mice is gated by GABAergic subparaventricular zone (SPZGABA) neurons, the major postsynaptic targets of the central circadian clock, the suprachiasmatic nucleus (SCN). Optogenetic mapping revealed that SPZGABA neurons receive input from vasoactive intestinal polypeptide SCN neurons and innervate neurons in the ventrolateral part of the ventromedial hypothalamus (VMHvl) known to regulate aggression. Additionally, VMH-projecting dorsal SPZ neurons are more active during early day than early night, and acute chemogenetic inhibition of SPZGABA transmission phase-dependently increases aggression. Finally, SPZGABA-recipient central VMH neurons directly innervate VMHvl neurons and activation of this intra-VMH circuit drove attack behavior. Altogether, we reveal a functional polysynaptic circuit by which the SCN clock regulates aggression.

Abstract
Background Workplace violence (WPV) against healthcare workers (HCWs) employed in psychiatric inpatient wards is a serious occupational issue that involves both staff and patients; the consequences of WPV may include increased service costs and lower standards of care. The purpose of this review was to evaluate which topics have been focused on in the literature and which are new in approaching the concern of patient violence against HCWs employed in psychiatric inpatient wards, in the past 20 years. Methods We searched for publications in PubMed and Web of Science using selected keywords. Each article was reviewed and categorized into one or more of the following four categories based on its subject matter: risk assessment, risk management, occurrence rates, and physical/nonphysical consequences. Results Our search resulted in a total of 64 publications that matched our inclusion criteria. The topics discussed, in order of frequency (from highest to lowest), were as follows: “risk assessment,” “risk management,” “occurrence rates,” and “physical/nonphysical consequences.” Schizophrenia, young age, alcohol use, drug misuse, a history of violence, and hostile-dominant interpersonal styles were found to be the predictors of patients’ violence. Conclusion Risk assessment of violence by patients appeared the way to effectively minimize the occurrence of WPV and, consequently, to better protect mental HCWs. We found paucity of data regarding psychologic sequelae of WPV. According to these findings, we suggest the need to better investigate the psychologic consequences of WPV, with the aim of checking the effective interventions to assist HCW victims of violence and to prevent psychologic illness.

Abstract
In international reviews of psychiatric inpatient violence, one study of all types of patient violence found hostility, involuntary admission, and longer hospital stays associated with violence. A second study of comparison-group papers of patient assaults found younger males with schizophrenia, past violence, and substance abuse assaultive. The present review of raw assault data studies assessed characteristics of assaultive patients worldwide. It was hypothesized that patients with schizophrenia would present greatest assault risk. There were three analyses: International/no American studies (reviewed earlier), European studies, and merged International/American studies. Results revealed that male and female patients with schizophrenia, affective disorders, personality disorders, and other diagnoses presented greatest worldwide risk. Results partially support earlier findings. Given that individual institutional studies in this review reported significant assailant characteristics, a second finding is the absence of most of these institutional characteristics in this international review. Possible explanations for findings and a detailed methodological review are presented.

Abstract
The symptom intensity and mortality of human diseases, conditions, and syndromes exhibit diurnal or 24 h patterning, e.g., skin: atopic dermatitis, urticaria, psoriasis, and palmar hyperhidrosis; gastrointestinal: esophageal reflux, peptic ulcer (including perforation and hemorrhage), cyclic vomiting syndrome, biliary colic, hepatic variceal hemorrhage, and proctalgia fugax; infection: susceptibility, fever, and mortality; neural: frontal, parietal, temporal, and occipital lobe seizures, Parkinson's and Alzheimer's disease, hereditary progressive dystonia, and pain (cancer, post-surgical, diabetic neuropathic and foot ulcer, tooth caries, burning mouth and temporomandibular syndromes, fibromyalgia, sciatica, intervertebral vacuum phenomenon, multiple sclerosis muscle spasm, and migraine, tension, cluster, hypnic, and paroxysmal hemicranial headache); renal: colic and nocturnal enuresis and polyuria; ocular: bulbar conjunctival redness, keratoconjunctivitis sicca, intraocular pressure and anterior ischemic optic neuropathy, and recurrent corneal erosion syndrome; psychiatric/behavioral: major and seasonal affective depressive disorders, bipolar disorder, parasuicide and suicide, dementia-associated agitation, and addictive alcohol, tobacco, and heroin cravings and withdrawal phenomena; plus autoimmune and musculoskeletal: rheumatoid arthritis, osteoarthritis, axial spondylarthritis, gout, Sjögren's syndrome, and systemic lupus erythematosus. Knowledge of these and other 24 h patterns of human pathophysiology informs research of their underlying circadian and other endogenous mechanisms, external temporal triggers, and more effective patient care entailing clinical chronopreventive and chronotherapeutic strategies.

Abstract
There have been several attempts made to reduce the occurrence of violence in hospital settings, with most professional organizations taking a stance. The impact of violent incidence on the therapeutic environment and the cost in human terms led to the declaration by the World Health Organization that violence is a public health problem. There are strategies for reducing violence that flow out of known trends. We sought to examine the trends in institutional violence in a contextual sense. We reviewed the records of all incidents of violence, categorized by severity, victims and trends over five years in a multilevel secure forensic hospital in Canada. The rate of violence perpetrated by female patients was significantly higher than for male patients. Higher occurrence of violence was recorded in the winter months compared with any other season and was related to unstructured activities. There is a window of opportunity to develop some engaging programmes during the long winter months and improve supervision at all times of unstructured activity. The reasons for increased women perpetration and the winter peak of violence require further investigation.

Abstract
OBJECTIVE To systematically review the types and proportions of antecedents of violence and aggression within psychiatric in-patient settings. METHOD Empirical articles and reports with primary data pertaining to violence and aggression within adult psychiatric in-patient settings were retrieved. For each study, prospective antecedent data were extracted. The extracted antecedent data were thematically analysed, and all higher-level themes were meta-analysed using rate data. RESULTS Seventy-one studies met the inclusion criteria, from which 59 distinct antecedent themes were identified and organised into nine higher-level themes. The higher-level antecedent theme 'staff-patient interaction' was the most frequent type of antecedent overall, precipitating an estimated 39% of all violent/aggressive incidents. An examination of the staff-patient interaction themes revealed that limiting patients freedoms, by either placing some sort of restriction or denying a patient request, was the most frequent precursor of incidents, accounting for an estimated 25% of all antecedents. The higher-level themes 'patient behavioural cues' and 'no clear cause' also produced other large estimates and were attributed to 38% and 33% of incidents overall. CONCLUSION This review underscores the influence that staff have in making in-patient psychiatric wards safe and efficacious environments.

Abstract
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.

Abstract
This review examines the research on ecologic factors that may contribute to or lessen the likelihood of inpatient unit violence. Understanding these factors can provide psychiatric inpatient unit staff with valuable therapeutic relational and cultural strategies to decrease violence. International and US studies from OVID Medline, CINAHL, and PsycInfo that evaluated aggression and violence on psychiatric inpatient units between 1983 and 2008 were included in this review. The review revealed that violence results from the complex interactions among the patient, staff, and culture of the specific unit. Inpatient psychiatric staff can decrease the potential for violence by using therapeutic relationship strategies such as using good communication skills, advocating for clients, being available, having strong clinical assessment skills, providing patient education, and collaborating with patients in treatment planning. Cultural improvements include providing meaningful patient activities and appropriate levels of stimulation and unit staffing.

Abstract
Crustaceans have frequently been used to study the neuroethology of both agonistic behavior and circadian rhythms, but whether their highly stereotyped and quantifiable agonistic activity is controlled by circadian pacemakers has, so far, not been investigated. Isolated marbled crayfish ( Procambarus spec.) displayed rhythmic locomotor activity under 12-h light:12-h darkness (LD12:12) and rhythmicity persisted after switching to constant darkness (DD) for 8 days, suggesting the presence of endogenous circadian pacemakers. Isogenetic females of parthenogenetic marbled crayfish displayed all behavioral elements known from agonistic interactions of previously studied decapod species including the formation of hierarchies. Groups of marbled crafish displayed high frequencies of agonistic encounters during the 1st hour of their cohabitation, but with the formation of hierarchies agonistic activities were subsequently reduced to low levels. Group agonistic activity was entrained to periods of exactly 24 h under LD12:12, and peaks of agonistic activity coincided with light-to-dark and dark-to-light transitions. After switching to DD, enhanced agonistic activity was dispersed over periods of 8-to 10-h duration that were centered around the times corresponding with light-to-dark transitions during the preceding 3 days in LD12:12. During 4 days under DD agonistic activity remained rhythmic with an average circadian period of 24.83 ± 1.22 h in all crayfish groups tested. Only the most dominant crayfish that participated in more than half of all agonistic encounters within the group revealed clear endogenous rhythmicity in their agonistic behavior, whereas subordinate individuals, depending on their social rank, initiated only between 19.4% and 0.03% of all encounters in constant darkness and displayed no statistically significant rhythmicity. The results indicate that both locomotion and agonistic social interactions are rhythmic behaviors of marbled crayfish that are controlled by light-entrained endogenous pacemakers.

Abstract
OBJECTIVE Treatment-emergent side effects are frequent events, particularly during the uptitration of antiepileptic drugs. So far, monitoring of such adverse events in outpatients has often been limited to intervals of weeks or months. We here report the application of a new device for temporally fine-grained assessment of objective well-being and cognitive performance using personal digital assistants (PDAs). METHODS Twenty adult patients with epilepsy participated in this pilot study. Ten received add-on treatment with levetiracetam. Ten patients with constant medication served as a control group. Differences between groups with respect to self-rated cognitive condition, psychophysical condition, aggressiveness, and cognitive test performance in a concentration test assessed three times daily (morning, early afternoon, and evening), over the course of 6 days, were analyzed. RESULTS Levetiracetam-treated patients manifested an early augmentation of self-rated aggressiveness, which increased in intensity over the course of days. Aggressiveness reached a maximum in the early afternoon across days. There were no major changes in cognitive performance, except for an increase in morning performance in the control group. CONCLUSIONS This study demonstrates the feasibility of a new method of ambulatory assessment of behavioral and cognitive data during titration of antiepileptic drugs. Significant changes in aggressiveness under add-on treatment with levetiracetam were found to be dependent on the time of assessment during the day. These results suggest that PDA-based ambulatory monitoring of patients with epilepsy may be a promising tool for early detection of drug-related side effects and, thus, may constitute a significant improvement in patient care.

Abstract
OBJECTIVE Research on the prevalence and causes of in-patient aggression has been hindered by the use of different methods for measuring aggression. Since Palmstierna and Wistedt presented the Staff Observation Aggression Scale (SOAS) in 1987, this data collection method has been used in various studies, which may make comparisons more useful. METHOD Studies with SOAS aggression data were compiled using MEDLINE, the Internet, and references from SOAS papers. RESULTS Reviews of studies on psychometric properties suggest fair to good inter-rater reliability and validity for SOAS assessments. The number of aggressive incidents per patient per year found on acute admissions wards (n = 38) considerably varied, with a range of 0.4-33.2 incidents (mean = 9.3). CONCLUSION Although the aggression data included in the present review were obtained in highly comparable ways, substantial differences in aggression rates between wards were still found. Some countries (e.g. the Netherlands) appear to have a relatively high incidence of aggression on acute wards.

Abstract
A circadian variation has been shown in the onset of acute medical diseases and we postulate that there is a circadian variation in emergency calls. We reviewed the 20,858 emergency calls addressed to the Emergency Coordinating Unit of the Hospital of Ferrara, Italy, from January 1 to December 31, 1998. Precise determination of the time of calls was available from the recordings. Total calls and subgroups by different diseases were categorized into 24 one-hour increments and analyzed for circadian rhythmicity by applying a partial Fourier series. A circadian variation was found for all subgroups, except for alcoholic intoxication. There was a peak frequency of calls in the morning hours for cardiologic, respiratory, and neurologic disease. There was a peak frequency of calls in the afternoon for trauma, neoplastic diseases, and acute poisoning. Organization of quantity and quality of Emergency Department (ED) staff should take into account the increased demand of specific facilities during certain hours of the day.
