RESUMO
Cardiovascular safety pharmacology and toxicology studies include vehicle control animals in most studies. Electrocardiogram data on common vehicles is accumulated relatively quickly. In the interests of the 3Rs principles it may be useful to use this historical information to reduce the use of animals or to refine the sensitivity of studies. We used implanted telemetry data from a large nonhuman primate (NHP) cardiovascular study (n = 48) evaluating the effect of moxifloxacin. We extracted 24 animals to conduct a n = 3/sex/group analysis. The remaining 24 animals were used to generate 1000 unique combinations of 3 male and 3 female NHP to act as control groups for the three treated groups in the n = 3/sex/group analysis. The distribution of treatment effects, median minimum detectable difference (MDD) values were gathered from the 1000 studies. These represent contemporary controls. Data were available from 42 NHP from 3 other studies in the same laboratory using the same technology. These were used to generate 1000 unique combinations of 6, 12, 18, 24 and 36 NHP to act as historical control animals for the 18 animals in the treated groups of the moxifloxacin study. Data from an additional laboratory were also available for 20 NHP. The QT, RR and QT-RR data from the three sources were comparable. However, differences in the time course of QTc effect in the vehicle data from the two laboratories meant that it was not possible to use cross-lab controls. In the case of historical controls from the same laboratory, these could be used in place of the contemporary controls in determining a treatment's effect. There appeared to be an advantage in using larger (≥18) group sizes for historical controls. These data support the opportunity of using historical controls to reduce the number of animals used in new cardiovascular studies.

Critical consciousness is a powerful tool for individuals from marginalized groups to transcend their oppressive conditions through engagement in critical reflection, motivation, and action. Nonetheless, the mental health benefits and costs of critical consciousness have received limited research attention. The present study utilized a longitudinal research design to explore the positive and negative relationships between critical consciousness and mental health among sexual minority individuals in different developmental stages. A total of 636 sexual minority individuals were involved in the baseline study and were asked to complete a follow-up questionnaire after one year. The results demonstrated a co-occurrence of positive and negative effects of critical consciousness on mental health among sexual minority individuals across time. On the one hand, critical consciousness was associated with better mental health outcomes through the mediation of internalized oppression and community connectedness. Specifically, critical consciousness was associated with reduced internalized oppression, which in turn was linked to lower levels of emotional distress. Critical consciousness was also associated with heightened levels of community connectedness, which in turn was associated with improved well-being. On the other hand, the results revealed a positive direct effect of critical consciousness on emotional distress, after controlling for internalized oppression and community connectedness. Notably, developmental stage moderated the relationship between critical consciousness and well-being. A negative association between critical consciousness and well-being was observed among sexual minority youth, whereas no such association was found among sexual minority adults. While the study highlights that critical consciousness can be a pedagogical and therapeutic tool for the liberation and empowerment of sexual minority individuals, it is equally important to acknowledge the potential risks associated with critical consciousness. Striking a balance between critical consciousness and self-care is crucial for sustaining meaningful engagement in the pursuit of social change.

Lack of disability-competent health care contributes to inequitable health outcomes for the largest minoritized population in the world: persons with disabilities. Health care professionals hold implicit and explicit bias against disabled people and report receiving inadequate disability training. While disability competence establishes a baseline standard of care, health professional educators must prepare a disability conscious workforce by challenging ableist assumptions and promoting holistic understanding of persons with disabilities. Future clinicians must recognize disability as an aspect of diversity, express respect for disabled patients, and demonstrate flexibility about how to care for disabled patients' needs. These skills are currently undervalued in medical training, specifically. This article describes how integrating disability consciousness into health professions training can improve health equity for patients with disabilities.

Following severe brain injuries, a subset of patients may remain in an altered state of consciousness; most of these patients require artificial feeding. Currently, a functional oral phase and the presence of exclusive oral feeding may constitute signs of consciousness. Additionally, the presence of pharyngo-laryngeal secretions, saliva aspiration, cough reflex and tracheostomy are related to the level of consciousness. However, the link between swallowing and consciousness is yet to be fully understood. The primary aim of this review is to establish a comprehensive overview of the relationship between an individual's conscious behaviour and swallowing (reflexive and voluntary). Previous studies of brain activation during volitional and non-volitional swallowing tasks in healthy subjects are also reviewed. We demonstrate that the areas activated by voluntary swallowing tasks (primary sensorimotor, cingulate, insula, premotor, supplementary motor, cerebellum, and operculum) are not specific to deglutitive function but are shared with other motor tasks and brain networks involved in consciousness. This review also outlines suitable assessment and treatment methods for dysphagic patients with disorders of consciousness. Finally, we propose that markers of swallowing could contribute to the development of novel diagnostic guidelines for patients with disorders of consciousness.

BACKGROUND: Following a severe acquired brain injury, neuro-orthopaedic disorders are commonplace. While these disorders can impact patients' functional recovery and quality of life, little is known regarding the assessment, management and treatment of neuro-orthopaedic disorders in patients with disorders of consciousness (DoC). OBJECTIVE: To describe neuro-orthopaedic disorders in the context of DoC and provide insights on their management and treatment. METHODS: A review of the literature was conducted focusing on neuro-orthopaedic disorders in patients with prolonged DoC. RESULTS: Few studies have investigated the prevalence of spastic paresis in patients with prolonged DoC, which is extremely high, as well as its correlation with pain. Pilot studies exploring the effects of pharmacological treatments and physical therapy show encouraging results yet have limited efficacy. Other neuro-orthopaedic disorders, such as heterotopic ossification, are still poorly investigated. CONCLUSION: The literature of neuro-orthopaedic disorders in patients with prolonged DoC remains scarce, mainly focusing on spastic paresis. We recommend treating neuro-orthopaedic disorders in their early phases to prevent complications such as pain and improve patients' recovery. Additionally, this approach could enhance patients' ability to behaviourally demonstrate signs of consciousness, especially in the context of covert awareness.

INTRODUCTION: Globally, faculty development initiatives in support of health professions (HP) educators continue to extend their remit. This work becomes more critical as HP curriculum renewal activities are influenced by needing to move beyond a biomedical focus attending to issues such as social accountability, social justice and health equity. This raises questions about how best to support our HP educators who may need to change their teaching practice as they embrace these more complex, social constructs. METHODS: The research question for this qualitative study was: What implications are there for faculty development that can support HP educators as they are expected to incorporate the principles of critical consciousness and social accountability into their teaching as part of a curriculum renewal process? Data from 11 focus group discussions and 11 subsequent individual interviews with HP educators from two undergraduate programmes were thematically analysed after which further analysis focussed on the implications of these findings for faculty development. Transformative learning theory and models about change provided a sensitising framework. RESULTS: Our findings pointed to an expanded role for HP educators and consequently also for those responsible for faculty development. Three main ideas were highlighted: Curriculum renewal catalyses a renewed need for faculty development, the nature of faculty development that can enable change and new foci for faculty development. CONCLUSIONS: Faculty development can make a significant contribution to enabling change, including in the context of curriculum renewal that often extends the roles and responsibilities of HP educators. When renewal seeks to shift fundamental curriculum principles, providing support to embrace this expanded remit results in an equally expanded remit for faculty developers-one that calls for initiatives that enable critical, dialogic encounters that might foster critical consciousness, leading to change in HP education. This challenges us, as faculty developers, to turn the mirror on ourselves to consider the nature of such expanded support.

BACKGROUND: Globally, the most important human rights and public health issue that sex workers face is their experience of high levels of violence (Kinnell, 2006, Kinnell, 2008, Alexander, 1999). Deering's systematic review estimated levels of sexual violence in sex working populations as being between 14% and 54% (Deering et al, 2014). AIMS: This international, robust mixed methods study will explore the frequency of sexual violence against sex workers, barriers in criminal justice and the legal consciousness of sex workers regarding their rights and consent. The hypothesis to be tested is that the safety of sex workers from sexual violence is mediated by the differing legal contexts of sex work environments. We will compare experiences across research sites in the context of legalisation (Nevada USA), client criminalisation (Northern Ireland), decriminalisation (New Zealand) and partial criminalisation (England, Scotland and Wales) [henceforth ESW]. METHODS: An international survey (n = 1,000) will be translated into several languages, to disaggregate experiences by demographic categories (gender, ethnicity, sexual orientation) and sex work sector (including online, street-based and brothels). Interviews (n = 100) with sex workers, police, prosecutors and service providers will be thematically analysed to explore legal consciousness, why the patterns occur and contextualise the statistical findings. These data will be supplemented with comparative legislative, policy and case analysis. Research study data will be used to compare the social factors and legal norms shaping sex workers experiences of sexual violence, justice and support interventions. Recommendations for a 'best practice' review of legal improvements and support interventions will be produced following completion of the study. Given the sensitive nature of the research, robust ethical and data protection mechanisms are in place. The research has ethical approval from each research site, an Advisory Board and trained, paid peer researchers to assist with data gathering, analysis and dissemination. The study will report findings in 2023/2024.

The purpose of this study is to investigate the impact of a set of green human resource management (HRM) practices on sustainable performance in Pakistani higher education institutions (HEIs), while also taking into account the mediating influence of environmental consciousness and green intellectual capital. Furthermore, the study aims to assess the association between environmental consciousness and green intellectual capital, along with the sustainable outcome. The study data was collected from 250 HR managers and executive officers who were responsible for implementing green HRM practices and sustainable performance in the education sector of Pakistan. Smart PLS-4 software was used to perform the statistical analysis of the data. According to the results of this study, green HRM practices play a substantial role in enhancing sustainable performance. The study also identified a link between green HRM practices and sustainable performance via environmental awareness and green intellectual capital. The research contributes to the theoretical paradigm's social cognitive theory by offering information on green HRM practice bundles and sustainable performance. The research also demonstrates that green intellectual capital and environmental consciousness operate as a bridge between green HRM practices and long-term sustainable performance. The study's findings have real-world applications for education, policymakers, and human resource managers at the highest levels. In order to achieve sustainable performance, the study emphasizes the significance of developing green intellectual capital and implementing green HRM practices.

INTRODUCTION: Profound changes in the healthcare sector and the growing, global shortage of healthcare workers are driving the demand to update and scale-up health professions education (HPE). At the same time, educational institutions are faced with increasing resource scarcity and decisions of where and how to allocate resources must be made conscious of costs. However, costs are known to be inaccurately and incompletely identified in HPE research. Therefore, to improve rigour in cost evidence and enable its use in decision-making, it is necessary to have a better understanding of the costs, stakeholders and cost identification methods being used in HPE research. This protocol has been developed to outline the rationale and methods for a scoping review of the literature intended to map the current state of cost and cost identification evidence in HPE. METHODS AND ANALYSIS: This protocol is developed in accordance with the Joanna Briggs Institute Manual for Evidence Synthesis. PubMed, ERIC, CINAHL and PsycInfo will be scoped for all types of English language publications from 2012 to 2022 that investigate costs associated with the education of health professionals. Two independent reviewers will assess publications for eligibility. Data will be extracted on the educational topic and context, the costs, cost types, perspectives and methods of cost identification as represented in the literature. ETHICS AND DISSEMINATION: No human participants are involved in this scoping review. All evidence for this study are sourced from public databases; therefore, ethical approval was not required. Final results will be disseminated through peer-reviewed publications and presented at conferences. TRIAL REGISTRATION NUMBER: A preliminary version of this protocol was prospectively registered on Open Science Framework (OSF) on 13 June 2022 and is available at https://doi.org/10.17605/OSF.IO/ET4XB.

OBJECTIVE: To develop an alert/verbal/painful/unresponsive (AVPU) scale assessment system based on automated video and speech recognition technology (AVPU-AVSR) that can automatically assess a patient's level of consciousness and evaluate its performance through clinical simulation. METHODS: We developed an AVPU-AVSR system with a whole-body camera, face camera, and microphone. The AVPU-AVSR system automatically extracted essential audiovisual features to assess the AVPU score from the recorded video files. Arm movement, pain stimulus, and eyes-open state were extracted using a rule-based approach using landmarks estimated from pre-trained pose and face estimation models. Verbal stimuli were extracted using a pre-trained speech-recognition model. Simulations of a physician examining the consciousness of 12 simulated patients for 16 simulation scenarios (4 for each of "Alert", "Verbal", "Painful", and "Unresponsive") were conducted under the AVPU-AVSR system. The accuracy, sensitivity, and specificity of the AVPU-AVSR system were assessed. RESULTS: A total of 192 cases with 12 simulated patients were assessed using the AVPU-AVSR system with a multi-class accuracy of 0.95 (95% confidence interval [CI] (0.92-0.98). The sensitivity and specificity (95% CIs) for detecting impaired consciousness were 1.00 (0.97-1.00) and 0.88 (0.75-0.95), respectively. The sensitivity and specificity of each extracted feature ranged from 0.88 to 1.00 and 0.98 to 1.00. CONCLUSIONS: The AVPU-AVSR system showed good accuracy in assessing consciousness levels in a clinical simulation and has the potential to be implemented in clinical practice to automatically assess mental status.

OBJECTIVE: Nonhuman primates (NHPs) are suitable for being model animals in the study of consciousness and loss of consciousness (LoC) with a similar brain structure and function to humans. However, there is no effective consciousness assessment scale for them. This study aimed to develop a behavioral assessment scale of consciousness for NHPs. METHODS: We constructed an initial indicator framework based on the clinical consciousness disorder assessment scales and the physiological characteristics, consciousness, and arousal behavior of NHPs. A two-round online Delphi method was conducted by a multidisciplinary expert panel to construct a behavioral assessment scale of consciousness for NHPs. The indicators and descriptions were revised according to the experts' feedback and then sent out for repeated consultations along with a summary of the results of the previous round of consultations. The accepted competencies of indicators were established with mean scores in two scoring criteria (importance and feasibility) ≥4.0, agreement rate with a rating of importance or essential ≥70.0%, and a coefficient of variation ≤0.25, as well as discussions of the research group. RESULTS: Consensus was achieved after the second round of consultations, which was completed by 28 experts who specialized in rehabilitation, neuroscience, psychology, neurosurgery, and neurology. A new behavioral assessment scale of consciousness for NHPs, including 37 items organized hierarchically within seven dimensions including visual function, auditory function, motor function, orofacial movements, arousal, brainstem reflexes, and respiration, was developed in this study. CONCLUSIONS: This study has successfully developed a behavioral assessment scale for measuring the conscious state of NHPs or NHP models with LoC. This tool is expected to facilitate future research into the underlying mechanisms of consciousness by providing a detailed and comprehensive means of measurement.

Spontaneous brain activity exhibits a highly structured modular organization that varies across individuals and reconfigures over time. Although it has been proposed that brain organization is shaped by an economic trade-off between minimizing costs and facilitating efficient information transfer, it remains untested whether modular variability and its changes during unconscious conditions might be constrained by the economy of brain organization. We acquired functional MRI and FDG-PET in rats under three different levels of consciousness induced by propofol administration. We examined alterations in brain modular variability during loss of consciousness from mild sedation to deep anesthesia. We also investigated the relationships between modular variability with glucose metabolism and functional connectivity strength as well as their alterations during unconsciousness. We observed that modular variability increased during loss of consciousness. Critically, across-individual modular variability is oppositely associated with functional connectivity strength and cerebral metabolism, and with deepening dosage of anesthesia, becoming increasingly dependent on basal metabolism over functional connectivity. These results suggested that, propofol-induced unconsciousness may lead to brain modular reorganization, which are putatively shaped by re-negotiations between energetic resources and communication efficiency.

BACKGROUND: Public Health Nurses (PHN) caring for vulnerable populations amid systemic inequality must navigate complex situations, and consequently they may experience serious moral distress known to be detrimental to PHN wellbeing. OBJECTIVE: Given PHN awareness of social inequities, the study aimed to determine if PHNs were motivated to enact social change and engage in social and political action to address inequality. DESIGN AND SAMPLE: A survey of 173 PHNs was conducted in fall 2022. The convenience sample was mainly female (96.5%), White (85%), had associate/bachelor's degrees (71.7%), and worked in governmental public health settings (70.7%). MEASURE: The study employed the Short Critical Consciousness Scales' subscales: Critical Reflection, Critical Motivation, and Critical Action. RESULTS: PHNs were highly motivated to address inequities (Critical Motivation = 20.83; SD = 3.16), with similarly high awareness (Critical Reflection = 17.89; SD = 5.18). However, social and political action scores were much lower (Critical Action = 7.13; SD = 2.63). A subgroup of PHNs with strong agreement regarding the impact of poverty were more likely to be younger (p = .039) and work in a community setting (p = .003); with higher scores across subscales (p < .001). CONCLUSIONS: High critical reflection and motivation among PHNs aligned with literature. Lower Critical Action scores warrant investigation into validity for PHNs, and possible role constraints.

We developed and validated an abbreviated version of the Coma Recovery Scale-Revised (CRS-R), the CRS-R For Accelerated Standardized Testing (CRSR-FAST), to detect conscious awareness in patients with severe traumatic brain injury in the intensive care unit. In 45 consecutively enrolled patients, CRSR-FAST administration time was approximately one-third of the full-length CRS-R (mean [SD] 6.5 [3.3] vs 20.1 [7.2] minutes, p < 0.0001). Concurrent validity (simple kappa 0.68), test-retest (Mak's ρ = 0.76), and interrater (Mak's ρ = 0.91) reliability were substantial. Sensitivity, specificity, and accuracy for detecting consciousness were 81%, 89%, and 84%, respectively. The CRSR-FAST facilitates serial assessment of consciousness, which is essential for diagnostic and prognostic accuracy. ANN NEUROL 2023;94:919-924.

For more than a decade, Dr. Brendesha Tynes has been at the forefront of empirical research examining the role of race in youth experiences with technology. Tynes' expansive corpus of research highlights the psychological, academic, and socioemotional implications and impact of online racial discrimination on child and adolescent development, with a particular focus on Black youth. Using explicitly strengths-based frameworks in both her research and mentoring, Tynes' contributions to the fields of psychology and education are vast. Given the American Psychological Association's recent shift to intentionally and urgently address racism, Tynes' scholarship is more timely than ever. Using a narrative review approach, we trace the intellectual contributions that Tynes has made to psychology, specifically, and the study of race and racism more broadly throughout her career. Particularly, we highlight key conceptual, methodological, and empirical work that have influenced the study of race in psychology. We conclude by sharing implications and possibilities for Tynes' research to influence race-conscious practices in psychological research, clinical, and pedagogical spheres.

Because consciousness does not necessarily translate into overt behaviour, detecting residual consciousness in noncommunicating patients remains a challenge. Bedside diagnostic methods based on EEG are promising and cost-effective alternatives to detect residual consciousness. Recent evidence showed that the cortical activations triggered by each heartbeat, namely, heartbeat-evoked responses (HERs), can detect through machine learning the presence of minimal consciousness and distinguish between overt and covert minimal consciousness. In this study, we explore different markers to characterize HERs to investigate whether different dimensions of the neural responses to heartbeats provide complementary information that is not typically found under standard event-related potential analyses. We evaluated HERs and EEG average non-locked to heartbeats in six types of participants: healthy state, locked-in syndrome, minimally conscious state, vegetative state/unresponsive wakefulness syndrome, comatose and brain-dead patients. We computed a series of markers from HERs that can generally separate the unconscious from the conscious. Our findings indicate that HER variance and HER frontal segregation tend to be higher in the presence of consciousness. These indices, when combined with heart rate variability, have the potential to enhance the differentiation between different levels of awareness. We propose that a multidimensional evaluation of brain-heart interactions could be included in a battery of tests to characterize disorders of consciousness. Our results may motivate further exploration of markers in brain-heart communication for the detection of consciousness at the bedside. The development of diagnostic methods based on brain-heart interactions may be translated into more feasible methods for clinical practice.
