Dopamine activity in the nigrostriatal pathway alters cue-induced risky choice patterns in female rats.

Deficits in cost/benefit decision making is a critical risk factor for gambling disorder. Reward-paired cues may play an important role, as these stimuli can enhance risk preference in rats. Despite extensive research implicating the dorsal striatum in the compulsive aspects of addiction, the role of nigrostriatal dopaminergic activity in cue-induced risk preference remains unclear, particularly in females. Accordingly, we examined the effects of manipulating the dopaminergic nigrostriatal pathway on cue-induced risky choice in female rats. TH:Cre rats were trained on the cued version of the rat Gambling Task. This task was designed such that maximal reward is attained by avoiding the high-risk, high-reward options and instead favouring the options associated with lower per-trial gains, as they feature less frequent and shorter time-out penalties. Adding reward-paired audiovisual cues to the task leads to greater risky choice on average. To assess the role of the nigrostriatal pathway, a viral vector carrying either Cre-dependent inhibitory or excitatory DREADD was infused into the substantia nigra. Rats then received clozapine-N-oxide either during task acquisition or after a stable performance baseline was reached. Inhibition of this pathway accelerated the development of risk preference in early sessions and increased risky choice during performance, but long-term inhibition actually improved decision making. Activation of this pathway had minimal effects. These results provide evidence for the involvement of the dopaminergic nigrostriatal pathway in cue-induced risk preference in females, therefore shedding light on its role in cost/benefit decision-making deficits and expanding our knowledge of the female dopaminergic system.

Excessive intragastric alcohol administration exacerbates hepatic encephalopathy and provokes neuronal cell death in male rats with chronic liver disease.

Hepatic encephalopathy (HE) is defined as decline in neurological function during chronic liver disease (CLD). Alcohol is a major etiological factor in the pathogenesis of fibrosis/cirrhosis and has also been documented to directly impact the brain. However, the role of alcohol in the development of HE in CLD remains unclear. Here, we investigated the impact of excessive alcohol administration on neurological deterioration in rats with CLD. Starting day 7 post-BDL surgery, rats were administered alcohol twice daily (51% v/v ethanol, 3 g/kg, via gavage) for 4 weeks. Motor coordination was assessed weekly using rotarod and anxiety-like behavior was evaluated with open field and elevated plus maze at 5 weeks. Upon sacrifice, brains were collected for western blot and immunohistochemical analyses to investigate neuronal integrity and oxidative stress status. Alcohol worsened motor coordination performance and increased anxiety-like behavior in BDL rats. Impairments were associated with decreased neuronal markers of NeuN and SMI311, increased apoptotic markers of cleaved/pro-caspase-3 and Bax/Bcl2, increased necroptosis markers of pRIP3 and pMLKL, decreased total antioxidant capacity (TAC), and increased 4-hydroxynonenal (4-HNE)modified proteins in the cerebellum of BDL-alcohol rats when compared to respective controls. Immunofluorescence confirmed the colocalization of cleaved caspase-3 and pMLKL in the granular neurons of the cerebellum of BDL-alcohol rats. Excessive alcohol consumption exacerbates HE which leads to associated apoptotic and necroptotic neuronal loss in the cerebellum of BDL-alcohol rats. Additionally, higher levels of 4-HNE and decreased TAC in the cerebellum of BDL-alcohol rats suggest oxidative stress is the triggering factor of apoptotic and necroptotic neuronal loss/injury.

The black box of the relationship between breast cancer patients and accompanying patients: the accompanied patients' point of view.

BACKGROUND: The PAROLE-Onco program was introduced in the province of Quebec, Canada in 2019. It integrates accompanying patients (APs), i.e., people who have been affected by cancer, into the clinical team as full members. These APs use their experiential knowledge with people undergoing treatment and with clinical teams. The aim of this paper is to evaluate, within the framework of two university medical centers, the perceptions of breast cancer patients who receive support from APs, particularly in terms of their active involvement in their care trajectory. METHODS: A qualitative study based on semi-structured interviews with accompanied patients was performed. Fourteen individual interviews were conducted between July and September 2021 with women presenting different profiles in terms of age, education, professional status, type of treatment, family situation, and clinical background. The data were analyzed using thematic analysis, focusing on patients' perceptions of APs' contributions and suggested improvements for accessing AP support. RESULTS: Three themes emerged from the semi-structured interviews: communication modalities used to connect patients with their APs, the characteristics of the support provided by APs, and the perceived effects of this support on the patients. Patients expressed a preference for telephone communication, highlighting its convenience and accessibility. The support provided by APs included emotional and informational support, neutrality, and adaptability. This relationship improved patient communication, reduced anxiety, helped regain control, and enhanced overall quality of life. The results emphasized the added value of APs in complementing the support offered by healthcare professionals. Patients noted the critical role of APs in helping them navigate the healthcare system, better understand their treatment processes, and manage their emotions. The ability of APs to provide practical advice and emotional reassurance was particularly valued. Overall, the findings underscored the significant impact of AP support on patients' experiences and highlighted areas for enhancing this service. CONCLUSION: This study highlights, during the care trajectory of people affected by breast cancer, APs' contribution to patients' emotional well-being because they improve, in particular, the management of emotions and communication with health professionals.

In 2019, we initiated the PAROLE-Onco program in Quebec, Canada, to support cancer patients by integrating Accompanying Patients (APs) into the medical team. These individuals, who have personally experienced cancer, join as full team members, sharing their insights with both patients and medical staff. Our study delved into the perceptions of breast cancer patients at two university hospitals regarding APs' involvement in their care trajectory. Through interviews with 14 women of diverse backgrounds and cancer experiences, we found that APs were instrumental in enhancing communication with doctors, facilitating the expression of challenging emotions, and aiding in treatment decisions. Patients valued the inclusion of APs in their care team and expressed gratitude for their support. Nonetheless, some encountered difficulties in reaching out to APs due to a lack of awareness or challenges involved in connecting. Overall, our research underscores the positive impact of involving APs in the care of breast cancer patients, and of enhancing emotional well-being and communication throughout the treatment journey.

Integrating accompanying patients into clinical oncology teams: limiting and facilitating factors.

OBJECTIVES: Since 2018, four establishments in Quebec have been instrumental in implementing the PAROLE-Onco program, which introduced accompanying patients (APs) into healthcare teams to improve cancer patients' experience. APs are patient advisors who have acquired specific experiential knowledge related to living with cancer, using services, and interacting with healthcare professionals. They are therefore in a unique and reliable position to be able to provide emotional, informational, cognitive and navigational support to patients who are dealing with cancer. We aimed to explore APs' perspectives regarding the limiting and facilitating factors in terms of how they are integrated into the clinical oncology teams. METHODS: A qualitative study based on semi-structured interviews and focus groups was conducted with 20 APs at the beginning of their intervention (T1) and, two years later, during a second data collection (T2). Limiting and facilitating factors of APs' integration into clinical teams were analyzed in terms of governance, culture, resources and tools. RESULTS: The limited factors raised by APs to be integrated into clinical teams include the following: confusion about the specific roles played by APs, lifting the egos of certain professionals who feel they are already doing what APs typically do, lack of identification of patient needs, absence of APs in project governance organizational boundaries, and team members' availability. Various communication challenges were also raised, resulting in the program being inadequately promoted among patients. Also mentioned as limiting factors were the lack of time, space and compensation. Creating opportunities for team members to meet with APs, building trust and teaching team members how APs' activities complement theirs were enhancing factors. Other facilitators include APs being involved in decision-making committees, being leaders in promoting the PAROLE-Onco program to patients and clinical team members and creating opportunities to communicate with team members to help enhance their work and provide feedback to improve patient services. Awareness of APs' added value for the team and patients is also a key facilitator. Regarding tools, offering accompanying services by telephone allows both patients and APs to benefit from the flexibility they need. CONCLUSION: Over time, APs were able to identify optimal factors for successful implementation. Recommendations include APs and professionals working in co-construction on organization, leadership, resources and status factors. This could help catalyze a change in culture within health establishments and allow people dealing with cancer to benefit from the experiential knowledge of other patients within their clinical team.

Interprofessional teams with and without nurse practitioners and the level of adherence to best practice guidelines in cardiac surgery: A retrospective study.

AIM: To examine the level of adherence to best-practice guidelines of interprofessional teams with acute care nurse practitioners (ACNPs) compared to interprofessional teams without ACNPs. DESIGN: A retrospective observational study was conducted in 2023. METHOD: A retrospective cohort was created including 280 patients who underwent a coronary artery bypass graft and/or a valve repair and hospitalised in a cardiac surgery unit of a university affiliated hospital in Québec (Canada) between 1 January 2019 to 31 January 2020. The level of adherence to best-practice guidelines was measured from a composite score in percentage. The composite score was created from a newly developed tool including 99 items across six categories (patient information, pharmacotherapy, laboratory tests, post-operative assessment, patient and interprofessional teams' characteristics). Multivariate linear and logistic regression models were computed to examine the effect of interprofessional teams with ACNPs on the level of adherence to best-practice guidelines. RESULTS: Most of the patients of the cohort were male and underwent a coronary artery bypass graft procedure. Patients under the care of interprofessional teams with ACNP were 1.72 times more likely to reach a level of adherence higher than 80% compared to interprofessional teams without ACNPs and were 2.29 times more likely to be within the highest quartile of the scores for the level of adherence to best-practice guidelines of the cohort. IMPACT: This study provides empirical data supporting the benefits of ACNP practice for patients, interprofessional teams and healthcare organisations. RELEVANCE FOR PRACTICE: Our findings identify the important contributions of interprofessional teams that include ACNPs using a validated instrument, as well as their contribution to the delivery of high quality patient care. REPORTING METHOD: This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) Statement: Guidelines for reporting observational studies guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Exploring Police Officer Experiences During the Transfer of People in Crisis to Emergency Department Nurses and Staff.

Police officers are increasingly tasked with responding to people in crisis (PIC), often resulting in transfers to emergency departments (EDs) where they can encounter challenges like long wait times, safety concerns, and conflicting perspectives between the medical and legal systems. This qualitative study explores the experiences of police officers during the transfer of PIC to ED nurses and staff. Eleven police officers were recruited and interviewed, providing contextual information about ED transfers in the greater Montreal area. The findings revealed that police officers face varied challenges in transferring PIC to different EDs, influenced by each hospital's unique characteristics, staffing, security, and organizational issues. Relationships with nurses significantly impact these experiences, ranging from positive interactions to tension and conflict influenced by staff biases and differing perceptions of the PIC. Effective communication between police and ED nurses is critical for accurate clinical evaluation and decision-making, yet often hindered by inconsistent information transfer and procedural gaps. Role confusion, divergent philosophies between police officers and ED nurses, and 'grey zones' further complicate transfers, emphasizing the need for clear communication and mutual understanding to ensure safe and effective care. The results underscore the need to ameliorate ED transfers through enhanced joint training for police officers and nurses, establishing hospital-precinct committees, and other intersectoral initiatives to promote collaboration. Such measures are essential to ensure effective and compassionate care of people in crisis while prioritizing safety for all involved.

An exploratory cross-sectional study of the effects of ongoing relationships with accompanying patients on cancer care experience, self-efficacy, and psychological distress.

BACKGROUND: Centre hospitalier de l'Université de Montréal in Canada introduced accompanying patients (APs) into the breast cancer care trajectory. APs are patients who have been treated for breast cancer and have been integrated into the clinical team to expand the services offered to people affected by cancer. This study describes the profiles of the people who received the support and explores whether one-offs vs ongoing encounters with APs influence their experience of care, on self-efficacy in coping with cancer, and on their level of psychological distress. METHODS: An exploratory cross-sectional study was carried out among patients to compare patients who had one encounter with an AP (G1) with those who had had several encounters (G2). Five questionnaires were administered on socio-demographic characteristics, care pathway, evaluation of the support experience, self-efficacy in coping with cancer, and level of psychological distress. Logbooks, completed by the APs, determined the number of encounters. Linear regression models were used to evaluate the associations between the number of encounters, patient characteristics, care pathway, number of topics discussed, self-efficacy measures in coping with cancer, and level of psychological distress. RESULTS: Between April 2020 and December 2021, 60% of 535 patients who were offered support from an AP accepted. Of these, one hundred and twenty-four patients participated in the study. The study aimed to recruit a minimum of 70 patients with the expectation of obtaining at least 50 participants, assuming a response rate of 70%. There were no differences between G1 and G2 in terms of sociodemographic data and care pathways. Statistical differences were found between G1 and G2 for impacts on and the return to daily life (p = 0.000), the return to the work and impacts on professional life (p = 0.044), announcement of a diagnosis to family and friends (p = 0.033), and strategies for living with treatment under the best conditions (p = 0.000). Significant differences were found on the topics of cancer (p = 0.000), genetic testing (p = 0.023), therapeutic options (p = 0.000), fatigue following treatment (p = 0.005), pain and discomfort after treatment or surgery (p = 0.000), potential emotions and their management (p = 0.000) and the decision-making processes (p = 0.011). A significant relationship was found between the two groups for patients' ability to cope with cancer (p = 0.038), and their level of psychological distress at different stages of the care pathway (p = 0.024). CONCLUSIONS: This study shows differences between one-time and ongoing support for cancer patients. It highlights the potential for APs to help patients develop self-efficacy and cope with the challenges of cancer treatment.

Accompanying patients in clinical oncology teams: Reported activities and perceived effects.

INTRODUCTION: Since 2018, four establishments in Quebec, Canada, have decided to implement the PAROLE-Onco programme, which introduced accompanying patients (APs) in healthcare teams to improve the experience of cancer patients. APs are patient advisors who have had a cancer treatment experience and who conduct consultations to complement the service offered by providing emotional, informational and educational support to patients undergoing treatments (e.g., radiotherapy, chemotherapy, surgery), mostly for breast cancer. We aimed to explore the evolution of APs' perspectives regarding their activities within the clinical oncology teams as well as the perceived effects of their intervention with patients, the clinical team and themselves. METHODS: A qualitative study based on semistructured interviews and focus groups was conducted with APs at the beginning of their intervention (T1) and 2 years afterwards (T2). The themes discussed were APs' activities and the perceived effects of their interventions on themselves, on the patients and on the clinical team. RESULTS: In total, 20 APs were interviewed. In T2, APs' activities shifted from listening and sharing experiences to empowering patients by helping them become partners in their care and felt generally more integrated into the clinical team. APs help patients feel understood and supported, alleviate stress and become partners in the care they receive. They also alleviate the clinical team's workload by offering a complementary service through emotional support, which, according to them, helps patients feel calmer and more prepared for their appointments with healthcare professionals. They communicate additional information about their patients' health journey, which makes the appointment more efficient for healthcare professionals. When APs accompany patients, they feel as if they can make a difference in patients' lives. Their activities are perceived by some as an opportunity to give back but also as a way of giving meaning to their own experience, in turn serving as a learning experience. CONCLUSION: By mobilizing their experiential knowledge, APs provide emotional, informational, cognitive and navigational support, which allows patients to be more empowered in their care and which complements professionals' scientific knowledge, thereby helping to refine their sensitivity to the patients' experiences. PATIENT OR PUBLIC CONTRIBUTION: Two patient-researchers have contributed to the study design, the conduct of the study, the data analysis and interpretation, as well as in the preparation and writing of this manuscript.

Sex is associated with differences in oxidative stress and susceptibility to severe hepatic encephalopathy in bile-duct ligated rats.

Hepatic encephalopathy (HE) is a debilitating neurological complication of chronic liver disease (CLD). Hyperammonemia plays an important role in HE's pathogenesis, acting synergistically with systemic oxidative stress. During CLD, muscle plays a compensatory role in detoxifying ammonia, and therefore muscle loss leads to an increase in the risk of developing HE. With most animal studies involving males, sex's impact on the development of CLD and associated complications such as HE and muscle loss remains unknown. Therefore, we aimed to identify the impact of sex on CLD, HE, and muscle mass loss in a rodent model of CLD. Liver injury markers, hyperammonemia, oxidative stress, muscle mass, and ammonia clearance were measured in female and male bile-duct ligated (BDL) rats. In addition, covert HE was assessed in females while ammonia-precipitated severe HE was assessed in female and male BDL rats, and male BDL rats treated with allopurinol (100 mg/kg), an antioxidant (xanthine oxidase inhibitor). Female BDL developed CLD and HE (impaired motor coordination and night activity) compared to respective SHAM. Hyperammonemia and muscle ammonia clearance were similar between female and male BDL. However, only female BDL rats did not develop muscle loss, brain edema, and short-term memory impairment (vs. female SHAM) and systemic oxidative stress and decreased albumin levels (vs. male BDL). Furthermore, both female BDL and allopurinol-treated male BDL rats were protected against ammonia-induced overt HE. In conclusion, female and male BDL rats develop distinct features of CLD and HE, with systemic oxidative stress playing a pivotal role in the susceptibility to ammonia-precipitated overt HE.

Rethinking how health care professionals cope with stress: A process model for COVID-19 and beyond.

ISSUE: Prior to the COVID-19 pandemic, there was evidence of challenges surrounding the psychological well-being of health care professionals (HCPs). HCPs already frayed psychological ability to cope risks being further compromised by COVID-19-related stresses. CRITICAL THEORETICAL ANALYSIS: Most research on stress, psychological distress, and coping among HCPs is done in a piecemeal manner without a theoretical model connecting these different but related phenomena. This critical advancement article aims to apply and extend Wheaton and Montazer's model of stressors, stress, and distress to the literature on HCPs, generally, and COVID-19, specifically, to summarize past and guide future research on HCPs' mental health, resilience, and coping. Our model describes how different sources of support buffer the effect of stressors on stress and how coping strategies moderate the effect of stress on psychological distress. ADVANCE: We extended the model by (a) distinguishing context from the support in HCPs' environment; (b) distinguishing adaptive from maladaptive coping strategies and their relationships with antecedents and outcomes; (c) describing the adverse impacts that psychological distress has on patients, HCPs, and health services; and (d) describing how such outcomes can become stressors, in turn, further contributing to HCPs' stress in a vicious cycle. PRACTICE IMPLICATIONS: Our model provides a broader perspective of HCPs' work-related mental health and helps guide the creation, implementation, and evaluation of different sources of support and promote adaptive coping strategies. This model helps HCPs, researchers, and health services managers better understand and respond to the well-being crisis HCPs are facing, especially during the pandemic.

Optimizing nurses' enacted scope of practice to its full potential as an integrated strategy for the continuous improvement of clinical performance: A multicentre descriptive analysis.

AIM: This study aims at better understanding the relationships between nurses' enacted scope of practice, work environment and work satisfaction, missed care, and organizational indicators of performance. BACKGROUND: The enacted scope of practice model describes the determinants and consequences of the actual enactment of the nursing scope of practice. METHOD: A correlational design was used to investigate nurses' enacted scope of practice in five Canadian healthcare centres. RESULTS: Suboptimal enacted scope of practice were found in the current sample. Significant positive correlations were found between the total enacted scope of practice score, use of qualification, control over tasks, decisional latitude and psychological demand as well as role ambiguity. Moreover, a higher enacted scope of practice was correlated with lower organizational indicators of short-term absenteeism. CONCLUSION: Results suggest an insufficient deployment of nurses' enacted scope of practice, likely caused by some job characteristics, leading to lower work satisfaction and negative patients and organizational outcomes. IMPLICATIONS FOR NURSING MANAGEMENT: Optimizing nurses' enacted scope of practice would be a significant integrated strategy for improving organizational performance, patient care and nurses' satisfaction and well-being. Nurses and frontline managers must be involved in the decision-making process necessary to improve nurses' enacted scope of practice.

Influence of caring for COVID-19 patients on nurse's turnover, work satisfaction and quality of care.

AIM: This study aims to examine, through the lens of the Job Demands-Resources model, the influence of caring for COVID-19 patients on nurse's perception of chronic fatigue, quality of care, satisfaction at work and intention to leave their organisation and the profession. BACKGROUND: Studies have examined how fear of COVID-19 contributes to the mental, physical and work adjustment among nurses. To date, few studies have been conducted examining how caring for patients with COVID-19 contributes to work outcomes among nurses. METHODS: This is a cross-sectional survey involving 1705 frontline nurses and licensed practical nurses in Quebec, Canada. From these, 782 reported caring for COVID-19 patients. RESULTS: High chronic fatigue, poor quality of care, lower work satisfaction and higher intention to leave their organisation were found for nurses caring for COVID-19 patients. Poorly prepared and overwhelmed nurses showed higher turnover intention than those well prepared and in control. CONCLUSIONS: There is an urgent need to provide support to nurses during the pandemic, with a long-term strategy to increase their retention. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse administrators play an important role in supporting their nurses during a pandemic in the form of education, training and policy development to positively impact quality of care and retention.

Bile-duct ligation renders the brain susceptible to hypotension-induced neuronal degeneration: Implications of ammonia.

Hepatic encephalopathy (HE) is a debilitating neurological complication of cirrhosis. By definition, HE is considered a reversible disorder, and therefore HE should resolve following liver transplantation (LT). However, persisting neurological complications are observed in as many as 47% of LT recipients. LT is an invasive surgical procedure accompanied by various perioperative factors such as blood loss and hypotension which could influence outcomes post-LT. We hypothesize that minimal HE (MHE) renders the brain frail and susceptible to hypotension-induced neuronal cell death. Six-week bile duct-ligated (BDL) rats with MHE and respective SHAM-controls were used. Several degrees of hypotension (mean arterial pressure of 30, 60 and 90 mm Hg) were induced via blood withdrawal from the femoral artery and maintained for 120 min. Brains were collected for neuronal cell count and apoptotic analysis. In a separate group, BDL rats were treated for MHE with the ammonia-lowering strategy ornithine phenylacetate (OP; MNK-6105), administered orally (1 g/kg) for 3 weeks before induction of hypotension. Hypotension 30 and 60 mm Hg (not 90 mm Hg) significantly decreased neuronal marker expression (NeuN) and cresyl violet staining in the frontal cortex compared to respective hypotensive SHAM-operated controls as well as non-hypotensive BDL rats. Neuronal degeneration was associated with an increase in cleaved caspase-3, suggesting the mechanism of cell death was apoptotic. OP treatment attenuated hyperammonaemia, improved anxiety and activity, and protected the brain against hypotension-induced neuronal cell death. Our findings demonstrate that rats with chronic liver disease and MHE are more susceptible to hypotension-induced neuronal cell degeneration. This highlights MHE at the time of LT is a risk factor for poor neurological outcome post-transplant and that treating for MHE pre-LT might reduce this risk.

Genetically engineered E. coli Nissle attenuates hyperammonemia and prevents memory impairment in bile-duct ligated rats.

Hyperammonemia associated with chronic liver disease (CLD) is implicated in the pathogenesis of hepatic encephalopathy (HE). The gut is a major source of ammonia production that contributes to hyperammonemia in CLD and HE and remains the primary therapeutic target for lowering hyperammonemia. As an ammonia-lowering strategy, Escherichia coli Nissle 1917 bacterium was genetically modified to consume and convert ammonia to arginine (S-ARG). S-ARG was further modified to additionally synthesize butyrate (S-ARG + BUT). Both strains were evaluated in bile-duct ligated (BDL) rats; experimental model of CLD and HE. METHODS: One-week post-surgery, BDLs received non-modified EcN (EcN), S-ARG, S-ARG + BUT (3x1011 CFU/day) or vehicle until sacrifice at 3 or 5 weeks. Plasma (ammonia/pro-inflammatory/liver function), liver fibrosis (hydroxyproline), liver mRNA (pro-inflammatory/fibrogenic/anti-apoptotic) and colon mRNA (pro-inflammatory) biomarkers were measured post-sacrifice. Memory, motor-coordination, muscle-strength and locomotion were assessed at 5 weeks. RESULTS: In BDL-Veh rats, hyperammonemia developed at 3 and further increased at 5 weeks. This rise was prevented by S-ARG and S-ARG + BUT, whereas EcN was ineffective. Memory impairment was prevented only in S-ARG + BUT vs BDL-Veh. Systemic inflammation (IL-10/MCP-1/endotoxin) increased at 3 and 5 weeks in BDL-Veh. S-ARG + BUT attenuated inflammation at both timepoints (except 5-week endotoxin) vs BDL-Veh, whereas S-ARG only attenuated IP-10 and MCP-1 at 3 weeks. Circulating ALT/AST/ALP/GGT/albumin/bilirubin and gene expression of liver function markers (IL-10/IL-6/IL-1ß/TGF-ß/α-SMA/collagen-1α1/Bcl-2) were not normalized by either strain. Colonic mRNA (TNF-α/IL-1ß/occludin) markers were attenuated by synthetic strains at both timepoints vs BDL-Veh. CONCLUSION: S-ARG and S-ARG + BUT attenuated hyperammonemia, with S-ARG + BUT additional memory protection likely due to greater anti-inflammatory effect. These innovative strategies, particularly S-ARG + BUT, have potential to prevent HE.

Elevated Serum Liver-Type Fatty Acid Binding Protein Levels in Non-acetaminophen Acute Liver Failure Patients with Organ Dysfunction.

BACKGROUND: Liver-type fatty acid binding protein (FABP1) has previously been demonstrated to improve prognostic discrimination in acetaminophen (APAP)-induced ALF but has not been investigated in other etiologies of ALF. AIM: To determine whether FABP1 levels (early: admission or late: days 3-5) are associated with 21-day transplant-free survival in non-APAP ALF. METHODS: FABP1 was measured in serum samples from 384 ALF patients (n = 88 transplant-free survivors (TFS), n = 296 died/LT-NTFS) using solid-phase enzyme-linked immunosorbent assay and analyzed with US ALFSG registry data. RESULTS: Of 384 ALF patients (autoimmune hepatitis n = 125, drug-induced liver injury n = 141, Hepatitis B n = 118), 177 (46%) patients received LT. Early FABP1 levels were significantly higher in ALF patients requiring vasopressor support (203.4 vs. 76.3 ng/mL) and renal replacement therapy (203.4 vs. 78.8 ng/mL; p < 0.001 for both). Late FABP1 levels were significantly higher in patients requiring mechanical ventilation (77.5 vs. 53.3 ng/mL), vasopressor support (116.4 vs. 53.3 ng/mL) and in patients with grade 3/4 hepatic encephalopathy (71.4 vs. 51.4 ng/mL; p = 0.03 for all). Late FABP1 levels were significantly lower in TFS patients (TFS 54 vs. NTFS 66 ng/mL; p = 0.049) but not admission (TFS 96 vs. NTFS 87 ng/mL; p = 0.67). After adjusting for significant covariates, serum FABP1 did not discriminate significantly between TFS and patients who died/received LT at day 21 either on admission (p = 0.29) or late (days 3-5, p = 0.087) time points. CONCLUSION: In this first report of FABP1 in non-APAP ALF, FABP1 levels at late time points (days 3-5) were significantly lower in ALF patients who were alive without transplant at day 21 but not after adjusting for covariates reflecting severity of illness. Higher FABP1 levels were associated with the presence of increased organ failure.

An Integrative Review of Organizational Factors Influencing Successful Large-Scale Changes in Healthcare.

OBJECTIVE: The aim of this study was to review organizational factors influencing successful large-scale change (LSC) in healthcare. BACKGROUND: LSC is necessary to achieve sustained and meaningful healthcare improvement. However, organizational readiness needs to be considered to promote successful LSC. METHODS: Four databases were searched for articles published between 2009 and 2018. Thematic analysis was used to identify enabling or hindering factors to LSC. RESULTS: Seven organizational factors were consistently described as facilitators of or barriers to successful LSC in healthcare: infrastructure support, organizational culture, leadership, change management approach, roles and responsibilities, networks, and measurement and feedback. CONCLUSION: The factors that emerged from this review are consistent with concepts of implementation but broadened and highlight learning organizations in successful LSC. The results of this review informed the development of a reflective tool on LSC for nurse leaders.

Healthcare professional disclosure of mental illness in the workplace: a rapid scoping review.

BACKGROUND: Although mental health difficulties are common among healthcare professionals (HCP), little research exists exploring the decision to disclose these difficulties in the healthcare context. AIMS: This rapid scoping review aims to explore HCP disclosure of mental health difficulties in the workplace. METHODS: The methodological framework was based on rapid and scoping review guidelines. A thematic synthesis approach was used for data analysis. RESULTS: Seventeen articles were included. Disclosure was found to be a process that starts with weighing its pros ("personal benefits", "personal beliefs", and "professional responsibility") and cons ("fears related to professional identity", "fears related to employment", "risk of stigmatization", and "personal experiences with mental health difficulties"). A decision-making process then occurs to help HCPs figure out how to disclose. Situations of nonconsensual disclosure can transpire through "third party disclosure" or "inadvertent disclosure". Disclosure results in outcomes including "positive experiences", "negative personal consequences" and "negative consequences related to others". CONCLUSION: Disclosure in healthcare and other workplaces is a complex process with few benefits and many potential repercussions. However, there is an opportunity to improve. Recognizing the value of and educating the workforce about HCPs with mental health difficulties will help work environments become safer for disclosure.

Innovative approaches to teaching vascular access to nursing students in the COVID-19 era.

PURPOSE: For the student nurse, peripheral venous cannulation is one of the most stressful skills to be learned. Although some healthcare employers/establishments offer courses on vascular access and infusion nursing as part of their onboarding programs, ultimately educational institutions should share the responsibility to ensure that graduating nurses can provide safe infusion therapies. METHODS: An innovative vascular access and infusion nursing (VAIN) curriculum was created and mapped onto the entry to practice undergraduate nursing program at McGill University in Montréal, Québec, Canada. This presented an opportunity to implement new teaching approaches. RESULTS: Students experienced multiple new teaching approaches including multimedia and experiential learning and live simulation to ensure acquisition of knowledge and psychomotor skills. The teaching approaches had to be rapidly modified with the advent of the COVID-19 pandemic. CONCLUSIONS: The VAIN curriculum emphasizes simulation and directed practice, seeking to increase competence, confidence, and knowledge. The pandemic underscored the need for flexibility and creativity in content delivery.

Mapping the peer-reviewed literature on accommodating nurses' return to work after leaves of absence for mental health issues: a scoping review.

BACKGROUND: The complexity of nursing practice increases the risk of nurses suffering from mental health issues, such as substance use disorders, anxiety, burnout, depression, and posttraumatic stress disorder (PTSD). These mental health issues can potentially lead to nurses taking leaves of absence and may require accommodations for their return to work. The purpose of this review was to map key themes in the peer-reviewed literature about accommodations for nurses' return to work following leaves of absence for mental health issues. METHODS: A six-step methodological framework for scoping reviews was used to summarize the amount, types, sources, and distribution of the literature. The academic literature was searched through nine electronic databases. Electronic charts were used to extract code and collate the data. Findings were derived inductively and summarized thematically and numerically. RESULTS: Academic literature is scarce regarding interventions for nurses' return to work following leaves of absence for mental health issues, and most focused on substance use concerns. Search of the peer-reviewed literature yielded only six records. The records were primarily quantitative studies (n = 4, 68%), published between 1997 and 2018, and originated in the United States (n = 6, 100%). The qualitative thematic findings addressed three major themes: alternative to discipline programs (ADPs), peer support, and return to work policies, procedures, and practices. CONCLUSIONS: While the literature supports alternative to discipline programs as a primary accommodation supporting return to work of nurses, more on the effectiveness of such programs is required. Empirical evidence is necessary to develop, maintain, and refine much needed return to work accommodations for nurses after leaves of absence for mental health issues.

Developing and maintaining the resilience of interdisciplinary cancer care teams: an interventional study.

BACKGROUND: Providing care to cancer patients is associated with a substantial psychological and emotional load on oncology workers. The purpose of this project is to co-construct, implement and assess multidimensional intervention continuums that contribute to developing the resilience of interdisciplinary cancer care teams and thereby reduce the burden associated with mental health problems. The project is based on resources theories and theories of empowerment. METHODS: The study will involve cancer care teams at four institutions and will use a mixed-model design. It will be organized into three components: (1) Intervention development. Rather than impose a single way of doing things, the project will take a participatory approach involving a variety of mechanisms (workshops, discussion forums, surveys, observations) to develop interventions that take into account the specific contexts of each of the four participating institutions. (2) Intervention implementation and assessment. The purpose of this component is to implement the four interventions developed in the preceding component, assess their effects and whether they are cost effective. A longitudinal quasi-experimental design will be used. Intervention monitoring will extend over 12 months. The effects will be assessed by means of generalized estimating equation regressions. A cost-benefit analysis will be performed to assess the cost-effectiveness of the interventions, taking an institutional perspective (costs and benefits associated with the intervention). (3) Analysis of co-construction and implementation process. The purpose of this component is to (1) describe and assess the approaches used to engage stakeholders in the co-construction and implementation process; (2) identify the factors that have fostered or impeded the co-construction, implementation and long-term sustainability of the interventions. The proposed design is a longitudinal multiple case study. DISCUSSION: In the four participating institutions, the project will provide an opportunity to develop new abilities that will strengthen team resilience and create more suitable work environments. Beyond these institutions, the project will generate a variety of resources (e.g.: work situation analysis tools; method of operationalizing the intervention co-development process; communications tools; assessment tools) that other oncology teams will be able to adapt and deploy elsewhere.
