Objectives: Psychiatric physicians may experience higher rates of assault than those in other fields. For many reasons, residents may be especially vulnerable. This study updates rates of assaults among US psychiatry residents as well as the reporting rates and emotional effects of these incidents.

Driver fatigue is a contributory factor in approximately 20% of vehicle crashes. While other causal factors (eg, drink-driving) have decreased in recent decades due to increased public education strategies and punitive measures, similar decreases have not been seen in fatigue-related crashes. Fatigued driving could be managed in a similar way to drink-driving, with an established point (ie, amount of prior sleep) after which drivers are "deemed impaired".

Regulatory guidance materials for fatigue management typically advise that employees be provided with days or weeks of advance notice of schedules/rosters. However, the scientific evidence underpinning this advice is unclear. A systematic search was performed on current peer reviewed literature addressing advance notice periods, which found three relevant studies.

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.

Context: Kefir, a traditional, fermented-milk beverage, has increasingly been promoted for various health benefits. The evidence from systematic reviews, however, is limited.

Objective: Evidence from randomized controlled trials testing oral consumption of fermented-milk kefir on any outcome of human health or disease.

Objective: Fatigue Risk Management Systems (FRMS) are a data-driven set of management practices for identifying and managing fatigue-related safety risks. This approach also considers sleep and work time, and is based on ongoing risk assessment and monitoring. This narrative review addresses the effectiveness of FRMS, as well as barriers and enablers in the implementation of FRMS.

Risks associated with fatigue that accumulates during work shifts have historically been managed through working time arrangements that specify fixed maximum durations of work shifts and minimum durations of time off. By themselves, such arrangements are not sufficient to curb risks to performance, safety, and health caused by misalignment between work schedules and the biological regulation of waking alertness and sleep. Science-based approaches for determining shift duration and mitigating associated risks, while addressing operational needs, require: (1) a recognition of the factors contributing to fatigue and fatigue-related risks; (2) an understanding of evidence-based countermeasures that may reduce fatigue and/or fatigue-related risks; and (3) an informed approach to selecting workplace-specific strategies for managing work hours.

Emergency services present a unique operational environment for the management of fatigue and sleep inertia. Communities request and often expect the provision of emergency services on a 24/7/365 basis. This can result in highly variable workloads and/or significant need for on-demand or on-call working time arrangements.

Purpose –: The purpose of this paper is to assess whether shift work, sleep loss and fatigue are related to short-term unplanned absences in policing.

Design/methodology/approach –: = 367 police officers from the Buffalo Police Department were studied. Day-by-day work and sick leave data were obtained from the payroll.

: Biomathematical models of fatigue (BMMF) predict fatigue during a work-rest schedule on the basis of sleep-wake histories. In the absence of actual sleep-wake histories, sleep-wake histories are predicted directly from work-rest schedules. The predicted sleep-wake histories are then used to predict fatigue.

Study Objectives: To compare rail workers' actual sleep-wake behaviors in normal operations to those predicted by a biomathematical model of fatigue (BMMF). To determine whether there are group-level residual sources of error in sleep predictions that could be modeled to improve group-level sleep predictions.

Methods: The sleep-wake behaviors of 354 rail workers were examined during 1,722 breaks that were 8-24 h in duration.

In families with infants between the ages of 6 and 18 months, sleep disruption can be significant, often putting parents at risk of a range of negative psychological and psychosocial consequences. Commonly prescribed sleep interventions typically involve 'extinction' methods, which require parents to completely or periodically ignore their infant's overnight cries. These methods can be effective in many, but not all cases.

Traditionally, working time arrangements to limit fatigue-related risk have taken a prescriptive approach, which sets maximum shift durations in order to prevent excessive buildup of fatigue (and the associated increased risk) within shifts and sets minimum break durations to allow adequate time for rest and recovery within and/or between shifts. Prescriptive rule sets can be successful when, from a fatigue-related risk standpoint, they classify safe work hours as permitted and unsafe work hours as not permitted. However, prescriptive rule sets ignore important aspects of the biological factors (such as the interaction between circadian and homeostatic processes) that drive fatigue, which are critical modulators of the relationship between work hours and fatigue-related risk.

Study Objectives: Recent experimental research indicates a substantial impact of shift work related fatigue on police officers' encounters with the public. In recent years, biomathematical models of fatigue have provided a new way to identify potential relationships between working time arrangements and job performance. This study focused on public complaints against police officers and determined whether the odds of a public complaint were associated with work schedules and/or a biomathematical model's predictions of fatigue and sleepiness.

The Working Time Society (WTS), and the International Commission on Occupational Health (ICOH) Scientific Committee on Shiftwork and Working Time, are twin organisations focused on conducting research, and informing practice, regarding the impact of work hours in general, and shiftwork in particular, on the efficiency, productivity, safety, well-being, health, and biological rhythms, of employees. Every 2-3 years since 1969, the WTS and ICOH have conducted a series of international symposia in Europe, Asia, Australia, North America, and South America. The purpose of these symposia is to provide a forum for the exchange of knowledge, and the discussion of contested issues, with researchers, employee representatives, regulators, and employers.

The longstanding human interest in dreams has led to a significant body of psychological and philosophical discourse, including research. Recently, however, dreams have been relegated to the periphery of clinical psychological practice. This is potentially problematic as clients continue to bring dreams to therapy and many psychologists lack the confidence or competence to respond effectively to dream material.

Objectives: The National Sleep Foundation (NSF) recommends 7 to 9 hours of sleep per night for adults ≥ 65 years of age. Sleep duration below 7h per night has been associated with negative health consequences, so enabling older adults to obtain at least 7 hours per night is important for health and wellbeing. However, little is known about behavioral factors that support sleep duration (≥ 7h/24h) in this group.
