The Impact of a Planned Change to Nurse Staffing Levels in Emergency Departments: A Pre-Test, Post-Test Design.

Aim: To examine burnout levels, nurse perceptions of the work environment, job satisfaction, intention to stay and quality of care for nurses working in emergency departments before and following a planned change to nurse staffing levels.

Design: A pre-post observational design.

Methods: A systematic approach (Nursing Hours per Patient Presentation) was introduced to determine nurse staffing levels based on patient presentations resulting in adjustments to nurse staffing.

Planned Changes to Nurse Leadership, Staffing and Skill-Mix: Impact on the Working Environment, Job Satisfaction and Intention to Leave.

Introduction: Job satisfaction and intention to leave have been consistently linked to the working environment. However, there are few studies of interventions for improving the environment or staff outcomes.

Aim: To determine the impact of implementing a framework for safe nurse staffing on the environment and staff outcomes.

Decision analysis of Integrated Pest Management: A case study on invasive sea lamprey in the Great Lakes Basin.

Integrated Pest Management (IPM) provides a powerful framework for addressing threats to human well-being caused by nuisance species including invasives. We examined the hypothesis that adaptive management could erode barriers to IPM implementation by developing a decision-analytic adaptive management framework for invasive sea lamprey (Petromyzon marinus) IPM in the Laurentian Great Lakes of North America. The framework addressed objectives associated with coordinating multiple sea lamprey control actions at the regional scale and objectives associated with internal validity of control actions.

De-escalating aggression in acute inpatient mental health settings: a behaviour change theory-informed, secondary qualitative analysis of staff and patient perspectives.

Background: De-escalation is often advocated to reduce harm associated with violence and use of restrictive interventions, but there is insufficient understanding of factors that influence de-escalation behaviour in practice. For the first time, using behaviour change and implementation science methodology, this paper aims to identify the drivers that will enhance de-escalation in acute inpatient and psychiatric intensive care mental health settings.

Methods: Secondary analysis of 46 qualitative interviews with ward staff (n = 20) and patients (n = 26) informed by the Theoretical Domains Framework.

Facilitators and barriers to community pharmacy PrEP delivery: a scoping review.

Introduction: Pre-exposure prophylaxis (PrEP) is an effective medication to reduce the risk of acquiring HIV. PrEP is available free of charge in the UK from sexual health clinics. Expanding PrEP delivery to community pharmacies holds promise and aligns with UK government goals to eliminate new cases of HIV by 2030.

Sensory trap leads to reliable communication without a shift in nonsexual responses to the model cue.

The sensory trap model of signal evolution suggests that males manipulate females into mating using traits that mimic cues used in a nonsexual context. Despite much empirical support for sensory traps, little is known about how females evolve in response to these deceptive signals. Female sea lamprey () evolved to discriminate a male sex pheromone from the larval odor it mimics and orient only toward males during mate search.

Protocol for monitoring and analyzing pheromone-mediated behavioral response of sea lamprey in a natural system.

Olfactory-mediated behaviors in fish are often examined in artificial microcosms that enable well-controlled treatments but fail to replicate environmental and social contexts. However, observing these behaviors in nature poses challenges. Here, we describe a protocol for recording sea lamprey (Petromyzon marinus) behaviors in a natural system.

Synergistic behavioral antagonists of a sex pheromone reduce reproduction of invasive sea lamprey.

Sex pheromones impart maximal attraction when their components are present at optimal ratios that confer balanced olfactory inputs in potential mates. Altering ratios or adding pheromone analogs to optimal mixtures may disrupt balanced olfactory antagonism and result in reduced attraction, however, tests in natural populations are lacking. We tested this hypothesis in sea lamprey (), a fish whose male sex pheromone attracts females when two critical components, 3-keto petromyzonol sulfate (3kPZS) and petromyzonol sulfate (PZS), are present at certain ratios.

The person-based development and realist evaluation of a pre-consultation form for GP consultations.

Background: Use of telephone, video and e-consultations is increasing. These can make consultations more transactional, potentially missing patients' concerns. This study aimed to develop a complex intervention to address patients' concerns more comprehensively in general practice and test the feasibility of this in a cluster-randomised framework.

The person-based development and realist evaluation of a summary report for GP consultations [version 1; peer review: 2 approved].

This study aimed to develop a complex intervention to address patients' concerns more comprehensively in general practice and test the feasibility of this in a cluster-randomised framework.

Attenuation and recovery of an avoidance response to a chemical antipredator cue in an invasive fish: implications for use as a repellent in conservation.

The detection of predation risk without direct engagement with a predator is an important driver of prey movement strategies. Consequently, the application of alarm cues may prove an effective tool in guiding the movements of fishes targeted for control or conservation. However, failure to contemplate the sensory, physiological and cognitive outcomes of repeated or persistent exposure to the cue will likely lead to poor performance of management practices.

Objective Nebuliser Adherence Data as "Proof" of Adherence in the Management of Cystic Fibrosis: A Qualitative Interview Study.

Purpose: Low adherence to medication via nebulisers is linked to poor clinical outcomes for people with Cystic Fibrosis (PWCF). Advances in technology allow electronic monitoring of nebuliser usage and feedback of objective adherence data to PWCF and clinical teams caring for them. CFHealthHub is a new intervention that collects and displays objective adherence data in easy-to-read formats with the aim of improving nebuliser adherence and health.

Convergent olfactory trace amine-associated receptors detect biogenic polyamines with distinct motifs via a conserved binding site.

Biogenic amines activate G-protein-coupled receptors (GPCRs) in the central nervous system in vertebrate animals. Several biogenic amines, when excreted, stimulate trace amine-associated receptors (TAARs), a group of GPCRs in the main olfactory epithelium, and elicit innate behaviors. How TAARs recognize amines with varying numbers of amino groups is largely unknown.

Maintaining face-to-face contact during the COVID-19 pandemic: a longitudinal qualitative investigation in UK primary care.

Background: In March 2020, the COVID-19 pandemic required a rapid reconfiguration of UK general practice to minimise face-to-face contact with patients to reduce infection risk. However, some face-to-face contact remained necessary and practices needed to ensure such contact could continue safely.

Aim: To examine how practices determined when face-to-face contact was necessary and how face-to-face consultations were reconfigured to reduce COVID-19 infection risk.

Using Crash Outcome Data Evaluation System (CODES) to examine injury in front vs. rear-seated infants and children involved in a motor vehicle crash in New York State.

Background: In New York State (NYS), motor vehicle (MV) injury to child passengers is a leading cause of hospitalization and emergency department (ED) visits in children aged 0-12 years. NYS laws require appropriate child restraints for ages 0-7 years and safety belts for ages 8 and up while traveling in a private passenger vehicle, but do not specify a seating position.

Methods: Factors associated with injury in front-seated (n = 11,212) compared to rear-seated (n = 93,092) passengers aged 0-12 years were examined by age groups 0-3, 4-7 and 8-12 years using the 2012-2014 NYS Crash Outcome Data Evaluation System (CODES).

Estimating the economic cost of nurse sensitive adverse events amongst patients in medical and surgical settings.

Aims: To identify the costs associated with nurse sensitive adverse events and the impact of these events on patients' length of stay.

Design: Retrospective cohort study using administrative hospital data.

Methods: Data were sourced from patient discharge information (N = 5544) from six acute wards within three hospitals (July 2016-October 2017).

Bile acid production is life-stage and sex-dependent and affected by primer pheromones in the sea lamprey.

Pheromonal bile salts are important for sea lampreys ( Linnaeus) to complete their life cycle. The synthesis and release of a releaser/primer pheromone 3-keto petromyzonol sulfate (3kPZS) by spermiating males have been well characterized. 3kPZS evokes sexual behaviors in ovulatory females, induces immediate 3kPZS release in spermiating males, and elicits neuroendocrine responses in prespawning adults.

Cardiac amyloidosis masquerading as acute coronary syndrome.

A 53-year-old man presented to a district general hospital with chest pain, ECG changes and a small high-sensitivity cardiac troponin I rise. There were no symptoms of heart failure. CT coronary angiography revealed moderate calcific disease and conventional angiography confirmed no flow limitation.

Implementation of remote consulting in UK primary care following the COVID-19 pandemic: a mixed-methods longitudinal study.

Background: To reduce contagion of COVID-19, in March 2020 UK general practices implemented predominantly remote consulting via telephone, video, or online consultation platforms.

Aim: To investigate the rapid implementation of remote consulting and explore impact over the initial months of the COVID-19 pandemic.

Design And Setting: Mixed-methods study in 21 general practices in Bristol, North Somerset and South Gloucestershire.

Moral injury in healthcare professionals: A scoping review and discussion.

Moral injury emerged in the healthcare discussion quite recently because of the difficulties and challenges healthcare workers and healthcare systems face in the context of the COVID-19 pandemic. Moral injury involves a deep emotional wound and is unique to those who bear witness to intense human suffering and cruelty. This article aims to synthesise the very limited evidence from empirical studies on moral injury and to discuss a better understanding of the concept of moral injury, its importance in the healthcare context and its relation to the well-known concept of moral distress.

Nursing, advocacy and public policy.

This article draws attention to the nature and importance of public policy. It argues that if nurses are to influence the quality of healthcare effectively, they must be engaged with policymakers to get nursing care issues on the policy agenda. There is an ethical imperative to do so, driven by the advocacy role of the nurse and rooted in the values base of nursing.

Analysis of graduating nursing students' moral courage in six European countries.

Background: Moral courage is defined as courage to act according to one's own ethical values and principles even at the risk of negative consequences for the individual. In a complex nursing practice, ethical considerations are integral. Moral courage is needed throughout nurses' career.
