Gender Difference in REM Sleep Behavior Disorder in Japanese Population: Polysomnography and Sleep Questionnaire Study

Rapid eye movement (REM) sleep behavior disorder (RBD) is generally common among males and is an established risk factor for neurodegenerative diseases. As the population ages, the prevalence of α-synucleinopathy (such as Parkinson's disease) is increasing. Additionally, the number of female patients is increasing in Japan. Therefore, we aimed to clarify the clinical characteristics of RBD from the perspective of gender differences in the Japanese population. The proportion of male RBD patients (65.2%) was significantly higher than that of female patients (34.8%). Additionally, female patients (70.5 ± 8.2 years) were significantly older than male patients (67.9 ± 8.0 years, p < 0.05). The mean score on the RBD Screening Questionnaire was significantly higher in male patients than in female (8.6 ± 2.9 vs. 7.7 ± 3.1, p < 0.05), while the mean score on the Pittsburgh Sleep Quality Index was significantly higher in males (5.9 ± 3.8 vs. 7.2 ± 3.600, p < 0.001). The Self-rating Depression Scale in females was 41.7 ± 8.5, and they were more likely to show depressive tendencies than males. In polysomnography, higher rates of obstructive sleep apnea and longer duration of stage N1 sleep were detected in males. After adjusting for age, BMI, and polysomnographic parameters, we found that female RBD patients had significantly worse sleep quality and rates of depression compared to male patients.

Effectiveness of Artificial Intelligence Methods in Personalized Aggression Risk Prediction within Inpatient Psychiatric Treatment Settings—A Systematic Review

Aggression risk assessments are vital to prevent injuries and morbidities amongst patients and staff in psychiatric settings. More recent studies have harnessed artificial intelligence (AI) methods such as machine learning algorithms to determine factors associated with aggression in psychiatric treatment settings. In this review, using Cooper’s five-stage review framework, we aimed to evaluate the: (1) predictive accuracy, and (2) clinical variables associated with AI-based aggression risk prediction amongst psychiatric inpatients. Databases including PubMed, Cochrane, Scopus, PsycINFO, CINAHL were searched for relevant articles until April 2022. The eight included studies were independently evaluated using critical appraisal tools for systematic review developed by Joanna Briggs Institute. Most of the studies (87.5%) examined health records in predicting aggression and reported acceptable to excellent accuracy with specific machine learning algorithms employed (area under curve range 0.75–0.87). No particular machine learning algorithm outperformed the others consistently across studies (area under curve range 0.61–0.87). Relevant factors identified with aggression related to demographic and social profile, past aggression, forensic history, other psychiatric history, psychopathology, challenging behaviors and management domains. The limited extant studies have highlighted a potential role for the use of AI methods to clarify factors associated with aggression in psychiatric inpatient treatment settings.

Prevalence and determinants of rapid eye movement sleep behavior disorder in the general population

STUDY OBJECTIVES

Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia associated with neurodegenerative synucleinopathies. Its prevalence is largely unknown. This study determined the prevalence and characteristics of RBD in the general population using gold-standard polysomnography.

METHODS

Full polysomnographic data from 1,997 participants (age = 59 ± 11.1 years, 53.6% women) participating in a population-based study (HypnoLaus, Lausanne, Switzerland) were collected. Sleep-related complaints and habits were investigated using various sleep measures including the Munich Parasomnia Screening (MUPS) questionnaire, which includes two questions evaluating complex motor behaviors suggestive of RBD. Full polysomnography was performed at home. For participants screening positive for RBD, muscle activity during REM sleep was quantified to diagnose RBD.

RESULTS

Three hundred sixty-eight participants endorsed dream-enactment behavior on either of the two MUPS questions, and 21 fulfilled polysomnographic criteria for RBD, resulting in an estimated prevalence of 1.06% (95% CI = 0.61-1.50), with no difference between men and women. Compared with RBD- participants, RBD+ took more frequently antidepressants and antipsychotics (23.8% vs. 5.4%, p = .005; 14.3% vs. 1.5%, p = .004, respectively) and were more frequently smokers or ex-smokers (85% vs. 56.6%, p = .011). On polysomnography, RBD+ had more stage N2 sleep (52 ± 11.5% vs. 46.3 ± 10.2%, p = .024) and less REM sleep (18 ± 6.4% vs. 21.9 ± 6.2%, p = .007), lower apnea-hypopnea index in REM sleep (3.8 ± 5.2 vs. 8.9 ± 13/hour, p = .035), and lower autonomic arousal index (31 ± 14.9 vs. 42.6 ± 19.5/hour, p = .002).

CONCLUSIONS

In our middle-to-older age population-based sample, the prevalence of RBD was 1.06%, with no difference between men and women. RBD was associated with antidepressant and antipsychotic use and with minor differences in sleep structure.

Poor sleep and reactive aggression: Results from a national sample of African American adults

BACKGROUND

We know that poor sleep can have important implications for a variety of health outcomes and some evidence suggests a link between sleep and aggressive behavior. However, few studies have looked at this relationship among African-Americans in the United States.

METHODS

Data from the National Survey of American Life (NSAL) and the NSAL Adult Re-Interview were used to examine associations between sleep duration and self-reported quality of sleep on reactive aggression among African American and Caribbean Black respondents between the ages of 18 and 65 (n = 2499).

RESULTS

Controlling for an array of sociodemographic and psychiatric factors, sleep was found to be significantly associated with reactive aggression. Specifically, individuals who reported sleeping on average less than 5 h per night were nearly three times more likely to report losing their temper and engaging in a physical fight (AOR = 3.13, 95% CI = 1.22-8.02). Moreover, individuals who reported being "very dissatisfied" with their sleep were more than two times more likely to report losing their temper and engaging in physical fights (AOR = 3.32, 95% CI = 1.50-7.33). Persons reporting everyday discrimination and problems managing stress were more likely to sleep poorly.

CONCLUSIONS

The present study is among the first to document an association between poor sleep and reactive violence among African-Americans. Findings suggest that reducing discrimination may lead to improved sleep and subsequently reduce forms of reactive violence.

Psychosocial background in incarcerated adolescents from Austria, Turkey and former Yugoslavia

Adolescents with a migration background account for a substantial proportion of juveniles in custody. Psychosocial adversities pose a significant risk for criminal behaviour. So far, the nature of psychosocial adversities experienced by migrant youth is understudied. The aim of this study was to explore differences in psychosocial background in three ethnic groups (Turkish, former-Yugoslavian and Austrian) of detained juveniles in Austria. A semi-structured interview (Multidimensional Clinical Screening Inventory for delinquent juveniles, MCSI) was used to assess psychosocial background (e.g., trauma, family background, forensic and psychiatric family history, school history, psychiatric treatment received and criminal history) in juveniles entering an Austrian pre-trial detention facility. Of the 370 eligible participants, the final study sample consisted of 278 juveniles. The ethnic distribution was as follows: 55.4% Austrian (mean age 16.88 years, S.D.=1.52), 14% Turkish (mean age 16.28 years, S.D.=1.23), 30.6% former-Yugoslavian (mean age 16.47 years, S.D.=1.41). In the Austrian sample, family dysfunction was significantly more prevalent than in the Turkish or former-Yugoslavian samples. Mental health services were significantly less used by juveniles with migration background. Turkish juveniles had a significantly poorer school performance than Austrians. Juveniles from former-Yugoslavia had significantly less often attended schools offering secondary education. The results suggest that detained juveniles with migration background are poorly integrated into the educational and mental health system of the host society. Family systems, even if substantially dysfunctional, seem to be perceived as more stable by migrant youth than by Austrian youth.

Evidence-based assessment with men

Men are almost universally underrepresented in psychological clinics and practices in the United States. One possible explanation for this underrepresentation is that men frequently conceal or obscure their emotional difficulties as a consequence of masculine gender role socialization. Men who subscribe to traditional, Western masculine values may be inclined to hide, minimize, or otherwise have difficulty expressing their psychological suffering, rendering this suffering difficult for clinicians to observe, diagnose, and treat. This manuscript describes an approach to the assessment process with men that integrates clinical reports on assessment and psychotherapy with men, values pertaining to our culture's construction of traditional masculinity, and empirical findings on psychological disorders more commonly observed in men.

Personal safety in the accident and emergency department

Violence and aggression continues to be a significant problem for staff practising in accident and emergency (A&E) areas. In recent years the number of articles examining factors related to violence and aggression in the A&E department have steadily increased, allowing for a more in-depth examination of data. This article considers the characteristics of individuals who assault A&E staff, introducing the reader to the "recreational fighter", an individual who enjoys and is attracted to violent confrontations. The article goes on to consider the role of gender, alcohol, age and social history in relation to the characteristics of individuals who assault nursing staff practising in A&E and offers a number of strategies for nursing staff to consider when attempting to minimize the risk of personal physical assault.

Community violence exposure in young adults

The United States is one of the most violent countries in the world, and this is being reflected in rates of young adults' lifetime exposure ranging from 76% to 82% for victimization and 93% to 96% for witnessing. These high rates are found despite these studies being conducted on relatively low-risk samples from rural areas, and the majority of violent acts reported being less life threatening than those reported by high-risk urban adolescents. Nonetheless, young adults with high levels of exposure report more psychological maladjustment including depressed mood, aggressive behavior, posttraumatic stress disorder symptomatology, and interpersonal problems. The cycle from exposure to later perpetration of aggression is discussed in terms of psychophysiological processes that may emerge from chronic violence exposure or interact with victimization to increase risk. Last, theoretical, clinical, and policy implications are suggested that include intervention and prevention programs targeting all forms of violence in urban and rural areas.

Coming to know ourselves as community through a nursing partnership with adolescents convicted of murder

This research applies Newman's hermeneutic-dialectic method of pattern recognition to the lives of 12 adolescent males convicted of murder who were invited to be co-investigators in the process of understanding patterns of meaningful relationships and experiences in their lives. Comparison of the 12 life patterns revealed a strikingly similar experience of interactions with the community and yielded insight into community pattern. The process of pattern recognition was found to be transformative. This article proposes a unitary-transformative process of community pattern recognition for nurses and communities interested in understanding complex community dynamics and engaging in healthy transformations.

Validation of the Interview Module for Intermittent Explosive Disorder (M-IED) in children and adolescents: a pilot study

We identified a subset of impulsive, aggressive children as having symptoms that met criteria for Intermittent Explosive Disorder (IED) using the Interview Module for Intermittent Explosive Disorder (M-IED). The M-IED was administered to 34 children and adolescents between the ages of 10 and 17. These data provide initial evidence for the M-IED as a useful instrument in the diagnosis of IED in adolescents. The M-IED displayed a high level of inter-rater reliability and adequate test-retest reliability. Construct validity was supported by the fact that the subjects with IED symptomatology had significantly more lifetime aggression, oppositionality, inattention and hyperactivity/impulsivity compared to community controls. In addition, the subjects with IED symptomatology had a significantly greater number of episodes of lifetime physical aggression and documented episodes of aggression while in residential treatment compared to psychiatric controls. The subjects with IED symptomatology had a greater number of positive screening questions for DSM-IV diagnoses using the Swanson, Nolan and Pelham questionnaire (SNAP-IV), particularly those related to IED and posttraumatic stress disorder than psychiatric controls.

A descriptive survey of Flemish delinquent adolescents

Previous research has shown that delinquent adolescents are characterized by a number of psychiatric problems. Most of these assessments, however, have been conducted on incarcerated adolescents. By means of semi-structured assessment (Child Assessment Schedule) and self-report measures, we assessed psychiatric status in a group of 72 delinquent adolescents, adjudicated before the Juvenile Court of Antwerp, Belgium. A significant difference was found between ethnic groups on self-report scores. Seventy per cent of subjects received at least one psychiatric diagnosis. The most prevalent diagnoses were conduct disorder (CD), substance abuse disorder and attention deficit hyperactivity disorder (ADHD). Less prevalent were post traumatic stress disorder (PTSD) and major depression (MD). As we found that an unselected sample of delinquent adolescents show a great number of psychiatric disorders, we suggest that psychiatric screening of delinquent adolescents should be done systematically. The predictive value of psychiatric assessment and subsequent treatment in delinquent adolescents should be investigated by future, prospective research.
