Abstract
BACKGROUND AND HYPOTHESIS Investigating the shared brain protein and genetic components of schizophrenia (SCZ) and bipolar I disorder (BD-I) presents a unique opportunity to understand the underlying pathophysiological processes and pinpoint potential drug targets. STUDY DESIGN To identify overlapping susceptibility brain proteins in SCZ and BD-I, we carried out proteome-wide association studies (PWAS) and Mendelian Randomization (MR) by integrating human brain protein quantitative trait loci with large-scale genome-wide association studies for both disorders. We utilized transcriptome-wide association studies (TWAS) to determine the consistency of mRNA-protein dysregulation in both disorders. We applied pleiotropy-informed conditional false discovery rate (pleioFDR) analysis to identify common risk genetic loci for SCZ and BD-I. Additionally, we performed a cell-type-specific analysis in the human brain to detect risk genes notably enriched in distinct brain cell types. The impact of risk gene overexpression on dendritic arborization and axon length in neurons was also examined. STUDY RESULTS Our PWAS identified 42 proteins associated with SCZ and 14 with BD-I, among which NEK4, HARS2, SUGP1, and DUS2 were common to both conditions. TWAS and MR analysis verified the significant risk gene NEK4 for both SCZ and BD-I. PleioFDR analysis further supported genetic risk loci associated with NEK4 for both conditions. The cell-type specificity analysis revealed that NEK4 is expressed on the surface of glutamatergic neurons, and its overexpression enhances dendritic arborization and axon length in cultured primary neurons. CONCLUSIONS These findings underscore a shared genetic origin for SCZ and BD-I, offering novel insights for potential therapeutic target identification.

Abstract
This article reviews the results of a randomized controlled trial, "Rapid Agitation Control with Ketamine in the Emergency Department: A Blinded, Randomized Controlled Trial" by D. Barbic et al. (2021), comparing time to sedation, level of sedation, and adverse outcomes between intramuscular ketamine versus intramuscular midazolam and haloperidol among acutely agitated patients presenting to the emergency department (ED). The findings are discussed in the context of practice change for patient stabilization within the ED. Emergency department nurse practitioners must employ continuing education and remain current with clinical practices and treatment options to ensure that patients receive optimal safe care. Although the use of midazolam and haloperidol has historically been the first-line treatment for the acutely agitated patient, use of ketamine shows promise in providing a safe alternative for expedited patient stabilization for acutely agitated patients presenting to the ED.

Abstract
OBJECTIVES We aimed to investigate the characteristics of adolescents with Bipolar disorder-I with irritability and agitation (Mania+IA) compared to those without irritability and agitation (Mania-IA) in a multi-center representative sample. METHODS Data of 145 patients from three tertiary-care inpatient units between 2016 and 2021 were obtained. Psychomotor agitation was defined as a score of ≥3 on the YMRS "Increased Motor Activity--Energy" item, irritability as a score of ≥4 on the YMRS 'irritability' item, and severity anchors of speech and thought disturbance on the YMRS '6 and 7' items. RESULTS Previous manic episodes (p = 0.013), involuntary hospitalization (p = 0.006), psychotic features (p = 0.001), formal thought disorder (p = 0.010) and aggressive/disruptive behavior (p = 0.021) were more frequent in the Mania+IA group. Conversely, depressive episodes (p = 0.006) and family history of depression (p = 0.024) were more frequent in the Mania-IA group. The Mania+IA had poorer functioning at the time of discharge. CONCLUSIONS Irritability and agitation were closely related to complications, psychotic symptoms and thought disorder. Assessment and monitoring of psychomotor agitation and irritability may help child and adolescent psychiatrists to predict clinical difficulties and appropriate interventions.

Abstract
INTRODUCTION Agitation is commonly encountered in people with bipolar disorder, particularly when experiencing a manic episode. The number of approved pharmacological agents to manage acute episodes of agitation in this population is limited. AREAS COVERED A search was conducted using the US National Library of Medicine PubMed.gov resource for English-language papers of clinical trials and reviews/meta-analyses, using the text words 'bipolar disorder' AND 'agitation,' as well as any papers with both two text words in the title, without any date restrictions. EXPERT OPINION Existing pharmacologic options approved by regulatory authorities for the treatment of acute episodes of agitation associated with bipolar disorder have similar degrees of efficacy but differ in their tolerability profiles and ease of use, giving clinicians an opportunity to individualize treatment. The goal is to treat mild-moderate agitation before it evolves into severe agitation, encouraging noninvasive pharmacologic treatment options. Inhaled loxapine and sublingual dexmedetomidine are newer options with rapid onset of action and may be preferable for patients willing to cooperate with treatment.

Abstract
BACKGROUND Coercive measures are associated with negative consequences for both patients and hospital staff. The aim of the study was to identify predictors for the use of restraints in the emergency department and in subsequent inpatient care. METHOD Retrospective routine clinical data of all patients admitted to the psychiatric departments of Vivantes Klinikum Am Urban in Berlin via the emergency department in 2019 was examined case-wise (n = 2584) as well as patient-wise (n = 2118). RESULTS Of all cases admitted via the emergency department, 195 cases (7.5%) experienced restraints and restraints combined with drug sedation during their inpatient treatment. Of the 2584 cases admitted via the emergency department, 195 cases (7.5%) experienced restraints and restraints combined with drug sedation during their inpatient treatment. These 195 cases experienced a total of 358 restraints and were distributed across 159 individuals. Multivariate regression analyses on patient-level show that age (p < .001), judicial placement (p < .001), and police referral in the presence of others (p < .001) had a statistically significant effect on the use of restraint. DISCUSSION The results indicate that certain patient characteristics increase the risk of restraints. A majority of the findings of this study underline previous research findings. However, ICD-10 diagnosis and gender do not prove to be significant variables, contrary to expectations based on previous.

Abstract
INTRODUCTION Especially when acutely ill, individuals with schizophrenia and bipolar disorder can present with agitated behavior. The initial approach to agitation management are non-pharmacologic strategies such as verbal de-escalation techniques; however, pharmacologic interventions may be needed. Dexmedetomidine is a selective alpha-2 adrenergic receptor agonist, and a sublingual formulation has been approved in the US for the treatment of agitation associated with schizophrenia and bipolar disorder in adults. AREAS COVERED The authors review the published literature on sublingual dexmedetomidine using the US National Library of Medicine's PubMed.gov resource. Pharmacodynamics, pharmacokinetics, and efficacy and tolerability findings are summarized. The authors also provide a discussion to its potential place in the treatment armamentarium. EXPERT OPINION Sublingual dexmedetomidine is an effective and well-tolerated pharmacologic option for the treatment of agitation associated with schizophrenia and bipolar disorder. The sublingual method of administration allows for a rapid onset of action with treatment effects beginning as early as 20 minutes after administration. Adverse effects include somnolence, hypotension, oral paresthesia, hypoesthesia, and dry mouth. Further study will be needed to evaluate sublingual dexmedetomidine in real-world patients receiving concomitant psychotropic medications.

Abstract
Psychomotor agitation is characterised by an increase in psychomotor activity, restlessness and irritability. People with psychomotor agitation respond by over-reacting to both intrinsic and extrinsic stimuli, experiencing stress and/or altered cognition. The objective of this study is to assess the clinical and sociodemographic profile of psychomotor agitation in patients with severe mental disorders. The study was carried out in Spain by means of multicentre cross-sectional convenience sampling involving 140 patients who had been admitted to psychiatric hospital units and had experienced an episode of psychomotor agitation between 2018 and 2021.Corrigan's Agitated Behaviour Scale was used to assess psychomotor agitation. The results show that the predominant characteristic in psychomotor agitation is aggressiveness, which is also the most reported factor in patients with severe mental disorder. Patients who also have anxiety develop psychomotor agitation symptoms of moderate/severe intensity. The clinical and sociodemographic profile found in our study is consistent with other studies on the prevalence of psychomotor agitation.

Abstract
Agitation is a common and potentially dangerous condition requiring rapid recognition and treatment in acute psychiatric units. Prompt intervention can prevent a patient with agitation from harming themselves, harming others, or needing restraints or seclusion. After the review of numerous guidelines, the Modified Agitation Severity Scale (MASS) agitation treatment protocol was developed to identify and manage agitation in an inpatient adult psychiatric setting. This protocol involved modifying an existing agitation scale and pairing scores with a treatment algorithm to indicate which behavioral and medication interventions would be most appropriate. All scoring and interventions were recorded in the electronic medical record (EMR). Three months of data were collected before and after the protocol was implemented. The new, modified scale had high reliability and correlated well with another validated agitation scale. Perceived patient safety was high during both study phases. Nurses' perceptions of safety trended upward after the protocol was implemented, though these differences were not significant, likely due to insufficient power. Although there was no decrease in seclusion events after implementation of the treatment protocol, there was a 44% decrease in restraint events and average restraint minutes per incident. Despite a potential increase in workload for nursing staff, implementation of the protocol did not increase burnout scores. Physicians continued to order the protocol for 55% of patients after the study period ended. These findings suggest that including a rapid agitation assessment and protocol within the EMR potentially improves nurses' perceptions of unit safety, helps assess treatment response, reduces time patients spend restrained, and supports decision making for nurses.

Abstract
IMPORTANCE Acute agitation is common in patients with bipolar disorder and requires urgent management to relieve distress and to prevent escalation to aggressive behavior. OBJECTIVE To evaluate the effect of orally absorbed, sublingual dexmedetomidine, a selective α2A-adrenergic receptor agonist on symptoms of acute agitation in patients with bipolar disorder. DESIGN, SETTING, AND PARTICIPANTS Phase 3, randomized, double-blind, placebo-controlled trial conducted in 15 sites in the US with enrollment between February 24, 2020, and April 27, 2020, and final follow-up on May 21, 2020. A total of 380 adults with bipolar I or II disorder were randomized and 362 completed the study. INTERVENTIONS Participants were randomized to 3 groups: sublingual dexmedetomidine 180 μg (n = 127), sublingual dexmedetomidine 120 μg (n = 127), or placebo (n = 126). MAIN OUTCOMES AND MEASURES The primary efficacy end point was the mean change from baseline at 2 hours for the Positive and Negative Syndrome Scale-Excited Component (PEC) total score. The range of possible total scores is 5 (absence of agitation) to 35 (extremely severe). The secondary end point was the earliest time of a statistically significant change in PEC total score from baseline for the drug vs placebo. On the primary efficacy end point, to account for multiplicity associated with comparing 2 sublingual dexmedetomidine doses with placebo, the 2-sided significance level for each dose vs placebo was set at .025. RESULTS Of 380 patients randomized (mean age, 45.6 years; 54.8% women; and 56.1% Black individuals), 378 (99.5%) self-administered the study medication and completed the study. Baseline agitation was mild to moderate, with an overall mean PEC total score of 18.0. Two hours after taking the medication, the mean changes from baseline in PEC total score were -10.4 for sublingual dexmedetomidine 180 μg, -9.0 for sublingual dexmedetomidine 120 μg, and -4.9 for placebo. Least-square mean differences from placebo in the sublingual dexmedetomidine groups at 2 hours were -5.4 (97.5% CI, -6.6 to -4.2) for 180 μg and -4.1 (97.5% CI, -5.3 to -2.9) for 120 μg (both doses P < .001 vs placebo). Treatment effects began 20 minutes after taking the medication among patients in the sublingual dexmedetomidine groups (least-square mean difference for 180 μg, -1.1 [97.5% CI, -2.0 to -0.2]; P = .007; for 120 μg, -1.0 [97.5% CI, -1.9 to -0.1]; P = .009). Adverse events occurred in 35.7% of patients taking 180 μg of dexmedetomidine, 34.9% taking 120 μg, and 17.5% taking placebo. The most common adverse events (≥5%) in the respective 180 μg, 120 μg, and placebo groups were somnolence (21.4% and 20.6% vs 4.8%); dry mouth (4.8% and 7.1% vs 0.8%); hypotension (6.3% and 4.8% vs 0%); and dizziness (5.6% and 5.6% vs 0.8%). CONCLUSIONS AND RELEVANCE Among patients with mild to moderate agitation associated with bipolar disorder, treatment with a sublingual film formulation of dexmedetomidine 120 μg or 180 μg, compared with placebo, resulted in significantly greater reduction in the agitation score at 2 hours. Further research is needed to understand the spectrum of patients for whom this treatment would be effective and feasible and to better understand the clinical importance of the observed effect size.

Abstract
OBJECTIVE The consequences and impact of violent behavior in schizophrenia are often serious, and identification of risk factors is of great importance to achieve early identification and effective management. METHODS This follow-up study sampled adult patients with schizophrenia in primary mental health care in a rural area of southern China, in which 491 participants completed a comprehensive questionnaire at baseline and the 2-year follow-up. Sociodemographic, clinical and psychological assessment data were collected from all participants. Paired sample T-Tests and the McNemar Test were performed to examine changes over the follow-up period. Generalized Estimating Equations (GEE) were used to analyze the risk factors for violent behavior. RESULTS The results showed that about two in five community-dwelling patients with schizophrenia reported violent behavior in the past year. At follow-up, participants were significantly less employed, had more times of hospitalization, more psychotropic medication, and severer depressive symptoms, but had better health-related quality of life than at baseline. Use of clozapine and better insight into medication decreased the possibility of violent behavior, while more severe positive symptoms, insomnia, as well as use of second-generation antipsychotics other than clozapine, antidepressants and mood stabilizers increased the possibility of violent behavior. CONCLUSIONS Risk evaluation, prevention and management of violence in patients with schizophrenia are demanded in primary mental health care.
