RESUMO

INTRODUCTION: Sexual orientation and gender identity (SOGI)-diverse patients are marginalized and poorly cared for in the emergency department, yet well-designed educational interventions to meet this gap are lacking. We developed, implemented, and assessed a novel multi-modal SOGI curriculum on health and cultural humility for emergency medicine physician trainees. METHODS: We conducted a prospective, single-arm evaluation of our educational intervention. A convenience sample of emergency medicine resident physicians (n = 21) participated in the facilitated curriculum including didactic and clinical simulation components. Participants completed a pre- and post-curriculum evaluation that assessed clinical skills, preparedness, attitudinal awareness, and basic knowledge in caring for SOGI-diverse patients. The content of the module was based on a scoping literature review and national needs assessment of Canadian emergency physicians, educators, and trainees along with expert collaborator and input from patient/community partners. The curriculum included a facilitated pre-brief, didactic presentation, clinical simulation modules, and a structured de-brief. Participant clinical skills were evaluated before and after the educational intervention. Our primary outcome was change in clinical preparedness, attitudinal awareness, and basic knowledge in caring for SOGI-diverse patients pre- and post-intervention. RESULTS: Our patient-centered, targeted emergency medicine SOGI health and cultural humility training resulted in a significant improvement in resident self-rated clinical preparedness, attitudes, and knowledge in caring for SOGI-diverse patients. This training was valued by participants. CONCLUSION: We have designed an effective, patient-centered curriculum in health and cultural humility for SOGI-diverse patients in EM. Other programs can consider using this model and developed resources in their jurisdictions to enhance provider capacities to care for this marginalized group.


RéSUMé: INTRODUCTION: L'orientation sexuelle et l'identité de genre (OSIG) - des patients de diverses natures sont marginalisés et mal soignés dans les services d'urgence, mais des interventions éducatives bien conçues pour combler cette lacune font défaut. Nous avons élaboré, mis en œuvre et évalué un nouveau programme multimodal de l'OSIG sur la santé et l'humilité culturelle pour les médecins d'urgence stagiaires. MéTHODES: Nous avons effectué une évaluation prospective de notre intervention éducative à un seul bras. Un échantillon pratique de médecins résidents en médecine d'urgence (n = 21) a participé au programme facilité, y compris les composantes didactiques et de simulation clinique. Les participants ont effectué une évaluation avant et après le programme d'études qui évaluait les compétences cliniques, la préparation, la sensibilisation aux attitudes et les connaissances de base en matière de soins aux patients atteints de diverses OSIG. Le contenu du module était fondé sur une analyse documentaire de portée et une évaluation des besoins nationaux des médecins d'urgence, des éducateurs et des stagiaires canadiens, ainsi que sur un collaborateur expert et les commentaires des patients et des partenaires communautaires. Le programme comprenait un pré-briefing animé, une présentation didactique, des modules de simulation clinique et un débriefing structuré. Les compétences cliniques des participants ont été évaluées avant et après l'intervention éducative. Notre résultat principal était un changement dans la préparation clinique, la sensibilisation aux attitudes et les connaissances de base dans les soins aux patients atteints de diverses OSIG avant et après l'intervention. RéSULTATS: Notre formation sur la santé et l'humilité culturelle axée sur le patient et ciblée en médecine d'urgence SOGI a permis d'améliorer considérablement la préparation clinique, les attitudes et les connaissances auto-évaluées des résidents en matière de soins aux patients SOGI-divers. Cette formation a été appréciée par les participants. CONCLUSIONS: Nous avons conçu un programme efficace et centré sur le patient en matière de santé et d'humilité culturelle pour les patients SOGI-divers en EM. D'autres programmes peuvent envisager d'utiliser ce modèle et d'élaborer des ressources dans leur administration pour améliorer les capacités des fournisseurs de soins à ce groupe marginalisé.

RESUMO

Infections remain a significant concern in patients receiving mechanical circulatory support (MCS), encompassing both durable and acute devices. This consensus manuscript provides updated definitions for infections associated with durable MCS devices and new definitions for infections in acute MCS, integrating a comprehensive review of existing literature and collaborative discussions among multidisciplinary specialists. By establishing consensus definitions, we seek to enhance clinical care, facilitate consistent reporting in research studies, and ultimately improve outcomes for patients receiving MCS.

RESUMO

BACKGROUND: Advancing health equity requires more contextualised evidence. OBJECTIVES: To synthesise published evidence using an existing framework on the origins of health disparities and determine care-related outcome disparities for residents of long-term care, comparing minoritised populations to the context-specific dominant population. DESIGN: Systematic review. SUBJECTS: Residents of 24-hour long-term care homes. METHODS: The protocol was registered a priori with PROSPERO (CRD42021269489). Literature published between 1 January 2000 and 26 September 2021, was searched, including studies comparing baseline characteristics and outcomes in minoritised versus dominant populations. Dual screening, two-reviewer verification for extraction, and risk of bias assessments were conducted to ensure rigour. Studies were synthesized using a conceptual framework to contextualise evidence according to multi-level factors contributing to the development of care disparities. RESULTS: Twenty-one of 34 included studies demonstrated disparities in care outcomes for minoritised groups compared to majority groups. Thirty-one studies observed differences in individual-level characteristics (e.g. age, education, underlying conditions) upon entry to homes, with several outcome disparities (e.g. restraint use, number of medications) present at baseline and remaining or worsening over time. Significant gaps in evidence were identified, particularly an absence of literature on provider information and evidence on the experience of intersecting minority identities that contribute to care-related outcome disparities in long-term care. CONCLUSION: This review found differences in minoritised populations' care-related outcomes. The findings provide guidance for future health equity policy and research-supporting diverse and intersectional capacity building in long-term care.

RESUMO

Background: Despite the demonstrated efficacy of approved COVID-19 vaccines, high levels of hesitancy were observed in the first few months of the COVID-19 vaccines' rollout. Factors contributing to vaccine hesitancy are well-described in the literature. Among the various strategies for promoting vaccine confidence, educational interventions provide a foundationally and widely implemented set of approaches for supporting individuals in their vaccine decisions. However, the evidence around the measurable impact of various educational strategies to improve vaccine confidence is limited. We conducted a scoping review with the aim of exploring and characterizing educational interventions delivered during the pandemic to support COVID-19 vaccine confidence in adults. Methods: We developed a search strategy with a medical information scientist and searched five databases, including Ovid MEDLINE and Web of Science, as well as grey literature. We considered all study designs and reports. Interventions delivered to children or adolescents, interventions on non-COVID-19 vaccines, as well as national or mass vaccination campaigns without documented interaction(s) between facilitator(s) and a specific audience were excluded. Articles were independently screened by three reviewers. After screening 4602 titles and abstracts and 174 full-text articles across two rounds of searches, 22 articles met our inclusion criteria. Ten additional studies were identified through hand searching. Data from included studies were charted and results were described narratively. Results: We included 32 studies and synthesized their educational delivery structure, participants (i.e., facilitators and priority audience), and content. Formal, group-based presentations were the most common type of educational intervention in the included studies (75%). A third of studies (34%) used multiple strategies, with many formal group-based presentations being coupled with additional individual-based interventions (29%). Given the novelty of the COVID-19 vaccines and the unique current context, studies reported personalized conversations, question periods, and addressing misinformation as important components of the educational approaches reviewed. Conclusions: Various educational interventions were delivered during the COVID-19 pandemic, with many initiatives involving multifaceted interventions utilizing both formal and informal approaches that leveraged community (cultural, religious) partnerships when developing and facilitating COVID-19 vaccine education. Train-the-trainer approaches with recognized community members could be of value as trust and personal connections were identified as strong enablers throughout the review.

RESUMO

Lung transplantation is the ultimate treatment for end-stage lung disease (ESLD) arising from various etiologies. This manuscript will focus on selected aspects of a theoretical perioperative lung transplantation plan, highlighting data-driven and theoretical techniques the authors would employ if they were the index patient undergoing surgery. Beginning with looking for a transplant center using an Internet search, patient advocacy organizations, and artificial intelligence guidance, the authors lay out a course for multidisciplinary care throughout the entire patient journey, ending with ideal approaches to recovery 6 months posttransplantation. Although the index case will focus on a theoretical patient with pulmonary fibrosis, the general management principles will be applicable across the entire spectrum of patients with ESLD presenting for lung transplantation.

RESUMO

INTRODUCTION: Preventing new parents who use drugs from bonding with and bodyfeeding their babies undermines public health. Because U.S. culture treats substance use as a moral failing rather than a health concern, punitive responses to perinatal substance use continue to dominate. This is particularly true for families of color, who are more likely to be targeted by the family regulation system. These approaches fail to protect families, and cause their own, separate harm. This article will lay out existing evidence surrounding bodyfeeding. Then, it will debunk harmful mythologies about drug use and human milk, and compare the risks associated with using drugs while bodyfeeding to those inherent in family separation. Finally, it will make the case for harm-reduction approaches over criminal ones. OBJECTIVES: The health risks associated with family separation are only rarely weighed against those associated with drug exposure through human milk. Our objective for this paper is to contribute new ways of framing the importance of keeping families together at birth, even when perinatal substance use is detected. METHODS: This manuscript is not based upon clinical study or patient data, and exclusively references studies and research publications that have been approved by the appropriate ethics committee and which have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. RESULTS: Significant research data support the position that the risks associated with family separation are arguably greater than those associated with exposure to substance use in human milk. CONCLUSIONS FOR PRACTICE: Harm reduction approaches should be favored over criminal approaches when perinatal substance use is detected or confirmed.


The harms of family separation have already been well-documented by public health and social science researchers. The risks associated with substance use and human milk have also been the subject of significant academic research. However, the authors have not come across any articles that weigh the health risks associated with family separation against those associated with drug exposure through human milk. This paper contributes new ways of framing the importance of keeping families together at birth, even when perinatal substance use is detected.

RESUMO

Extracorporeal membrane oxygenation (ECMO) is an established advanced life support system, providing temporary cardiac and/or respiratory support in critically ill patients. Fungal infections are associated with increased mortality in patients on ECMO. Antifungal drug dosing for critically ill patients is highly challenging because of altered pharmacokinetics (PK). PK changes during critical illness; in particular, the drug volume of distribution (Vd) and clearance can be exacerbated by ECMO. This article discusses the available literature to inform adequate dosing of antifungals in this patient population. The number of antifungal PK studies in critically ill patients on ECMO is growing; currently available literature consists of case reports and studies with small sample sizes providing inconsistent findings, with scant or no data for some antifungals. Current data are insufficient to provide definitive empirical drug dosing guidance and use of dosing strategies derived from critically patients not on ECMO is reasonable. However, due to high PK variability, therapeutic drug monitoring should be considered where available in critically ill patients receiving ECMO to prevent subtherapeutic or toxic antifungal exposures.

RESUMO

BACKGROUND: The incidence and clinical importance of vasoplegia after lung transplantation remains poorly studied. We describe the incidence of vasoplegia and its association with complications after lung transplantation. METHODS: Perioperative data of 279 lung transplant recipients operated on from 2015 to 2020 in a UK hospital were analysed retrospectively. RESULTS: Vasoplegia occurred in 41.6% of patients after lung transplantation (mild, 31.0%; moderate, 55.2%; severe, 13.8%). Compared with non-vasoplegic patients, vasoplegic patients had a higher incidence of any acute kidney injury, defined by Kidney Disease Improving Global Outcomes (KDIGO) criteria (78.5% vs 65%, P=0.015), renal replacement therapy (47.4% vs 24.5%, P<0.001), and delayed chest closure (18.4% vs 9.2%, P=0.025); were ventilated longer (70 [32-368] vs 34 [19-105] h, P<0.001); and stayed longer in the ICU (12.9 [5-30] vs 6.8 [3-20] days, P<0.001). Mortality at 30 days and 1 yr was higher in patients with vasoplegia (11.2% vs 5.5% and 20.7% vs 11.7%, P=0.039, respectively). Severe vasoplegia represented a predictor of longer-term mortality (hazard ratio=1.65, P=0.008). Underlying infectious disease, increased BMI, higher preoperative pulmonary artery systolic pressure and bilirubin levels, lower glomerular filtration rate, and increased fresh frozen plasma transfusion were predictors of vasoplegia severity. Neutrophilia, leucocytosis, and increased C-reactive protein were associated with vasoplegia, but release of the neutrophil activation markers myeloperoxidase and heparin-binding protein was similar between groups. CONCLUSIONS: Influenced by preoperative status as well as procedural factors and inflammatory response, vasoplegia is a common and critical condition after lung transplantation with worse short-term outcomes and long-term survival.

RESUMO

Fungal infections are common and frequently associated with clinical failure in patients receiving extracorporeal membrane oxygenation (ECMO). Antifungal drugs have physicochemical characteristics associated with a higher likelihood of sequestration onto ECMO circuitry potentially leading to a subtherapeutic drug concentration. The percentage of sequestration of the antifungal drugs-caspofungin, posaconazole, and voriconazole-was determined using an ex vivo ECMO model. The circuits were primed with whole human blood, sodium chloride 0.9%, and human albumin solution. Serial 2 ml samples were taken at baseline, 0.5, 1, 2, 6, 12, and 24 hours after drug addition, paired with non-ECMO controls stored in a water bath at 37°C. Mean loss from the blood-primed ECMO circuits and controls at 24 hours relative to baseline were 80% and 61% for caspofungin ( p = ns), 64% and 11% for posaconazole ( p < 0.005), and 27% and 19% for voriconazole ( p < 0.05). Calculated AUC 0-24 showed a 44% for caspofungin ( p = ns), 30.6% posaconazole ( p < 0.005), and 9% loss for voriconazole ( p = 0.003) compared with the controls, suggesting therapeutic concentrations of these antifungal agents cannot be guaranteed with standard dosing in patients on ECMO. Posaconazole exhibited the greatest loss to the ECMO circuit correlating with both high lipophilicity and protein binding of the drug.

RESUMO

A transformative approach to maternal health promotion should be mother-centred, context-driven and grounded in lived experiences. Health promotion can achieve this by drawing on its disciplinary roots to extend and reorient maternal health promotion towards an approach of non-stigmatizing and equitable health promotion that has mothers' well-being at the centre, particularly giving credit to marginalized, 'non-normative' maternities. This article draws on data from 18 workshops EN conducted across Aotearoa New Zealand, including 268 maternal health stakeholders. Drawing on design thinking, participants reimagined what a maternal health promotion approach informed by the Ottawa Charter action areas could comprise. The five themes included building connected systems close to home, developing mothering/parenting skills, addressing upstream determinants, mother-centred care and funding, and creating a collective mothering village. We discuss how these areas could better meet the unique challenges of transitioning to motherhood. Rather than focussing only on individual behaviours, many ideas reveal broader environmental and structural determinants. We link the themes to current literature and advance the agenda for centring the maternal in maternal health promotion.

RESUMO

OBJECTIVES: We sought to evaluate the safety and effectiveness of fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (CDI) in pediatric immunocompromised (IC) patients. METHODS: This is a multicenter retrospective cohort study of pediatric participants who underwent FMT between March 2013 and April 2020 with 12-week follow-up. Pediatric patients were included if they met the definition of IC and were treated with FMT for an indication of recurrent CDI. We excluded patients over 18 years of age, those with incomplete records, insufficient follow-up, or not meeting study definition of IC. We also excluded those treated for Clostridioides difficile recurrence without meeting the study definition and those with inflammatory bowel disease without another immunocompromising condition. RESULTS: Of 59 pediatric patients identified at 9 centers, there were 42 who met inclusion and no exclusion criteria. Included patients had a median age of 6.7 years. Etiology of IC included: solid organ transplantation (18, 43%), malignancy (12, 28%), primary immunodeficiency (10, 24%), or other chronic conditions (2, 5%). Success rate was 79% after first FMT and 86% after 1 or more FMT. There were no statistically significant differences in patient characteristics or procedural components when patients with a failed FMT were compared to those with a successful FMT. There were 15 total serious adverse events (SAEs) in 13 out of 42 (31%) patients that occurred during the follow-up period; 4 (9.5%) of which were likely treatment-related. There were no deaths or infections with multidrug resistant organisms during follow-up and all patients with a SAE fully recovered. CONCLUSIONS: The success rate of FMT for recurrent CDI in this pediatric IC cohort is high and mirrors data for IC adults and immunocompetent children. FMT-related SAEs do occur (9.5%) and highlight the need for careful consideration of risk and benefit.

RESUMO

Interstitial lung disease and associated fibrosis occur in a proportion of individuals who have recovered from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection through unknown mechanisms. We studied individuals with severe coronavirus disease 2019 (COVID-19) after recovery from acute illness. Individuals with evidence of interstitial lung changes at 3 to 6 months after recovery had an up-regulated neutrophil-associated immune signature including increased chemokines, proteases, and markers of neutrophil extracellular traps that were detectable in the blood. Similar pathways were enriched in the upper airway with a concomitant increase in antiviral type I interferon signaling. Interaction analysis of the peripheral phosphoproteome identified enriched kinases critical for neutrophil inflammatory pathways. Evaluation of these individuals at 12 months after recovery indicated that a subset of the individuals had not yet achieved full normalization of radiological and functional changes. These data provide insight into mechanisms driving development of pulmonary sequelae during and after COVID-19 and provide a rational basis for development of targeted approaches to prevent long-term complications.

RESUMO

BACKGROUND: Antifungal stewardship (AFS) lags behind antimicrobial stewardship (AMS) in terms of implementation, evidence base, and workforce experience. Solid-organ transplantation (SOT) carries a significant risk of invasive fungal infection, with high associated mortality, and is therefore associated with significant opportunities to optimize antifungal use. METHODS: A literature search for the terms "antifungal stewardship" and "solid-organ transplant" revealed a small evidence base to support AFS programs in this patient group. RESULTS: There is significant overlap in the methodology used in AMS and AFS programs, with notable differences in diagnostics, which are discussed in detail. The primary AFS interventions tested in SOT recipients are implementation of clinical guidelines and care bundles, digital enablers of AFS, and post-prescription review/audit and feedback. CONCLUSION: There is an urgent need for further research to support effective AFS strategies in this highly susceptible population.

RESUMO

Antibiotic resistance is a growing health threat. There is an urgent and critical need to develop new antimicrobial modalities and therapies. Here, a set of hemithioindigo (HTI)-based molecular machines capable of specifically killing Gram-positive bacteria within minutes of activation with visible light (455 nm at 65 mW cm-2 ) that are safe for mammalian cells is described. Importantly, repeated exposure of bacteria to HTI does not result in detectable development of resistance. Visible light-activated HTI kill both exponentially growing bacterial cells and antibiotic-tolerant persister cells of various Gram-positive strains, including methicillin-resistant S. aureus (MRSA). Visible light-activated HTI also eliminate biofilms of S. aureus and B. subtilis in as little as 1 h after light activation. Quantification of reactive oxygen species (ROS) formation and protein carbonyls, as well as assays with various ROS scavengers, identifies oxidative damage as the underlying mechanism for the antibacterial activity of HTI. In addition to their direct antibacterial properties, HTI synergize with conventional antibiotics in vitro and in vivo, reducing the bacterial load and mortality associated with MRSA infection in an invertebrate burn wound model. To the best of the authors' knowledge, this is the first report on the antimicrobial activity of HTI-based molecular machines.

RESUMO

The increasing occurrence of antibiotic-resistant bacteria and the dwindling antibiotic research and development pipeline have created a pressing global health crisis. Here, we report the discovery of a distinctive antibacterial therapy that uses visible (405 nanometers) light-activated synthetic molecular machines (MMs) to kill Gram-negative and Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus, in minutes, vastly outpacing conventional antibiotics. MMs also rapidly eliminate persister cells and established bacterial biofilms. The antibacterial mode of action of MMs involves physical disruption of the membrane. In addition, by permeabilizing the membrane, MMs at sublethal doses potentiate the action of conventional antibiotics. Repeated exposure to antibacterial MMs is not accompanied by resistance development. Finally, therapeutic doses of MMs mitigate mortality associated with bacterial infection in an in vivo model of burn wound infection. Visible light-activated MMs represent an unconventional antibacterial mode of action by mechanical disruption at the molecular scale, not existent in nature and to which resistance development is unlikely.

RESUMO

Primary graft dysfunction (PGD) is a major determinant of morbidity and mortality following lung transplantation. Delineating basic mechanisms and molecular signatures of PGD remain a fundamental challenge. This pilot study examines if the pulmonary volatile organic compound (VOC) spectrum relate to PGD and postoperative outcomes. The VOC profiles of 58 bronchoalveolar lavage fluid (BALF) and blind bronchial aspirate samples from 35 transplant patients were extracted using solid-phase-microextraction and analyzed with comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry. The support vector machine algorithm was used to identify VOCs that could differentiate patients with severe from lower grade PGD. Using 20 statistically significant VOCs from the sample headspace collected immediately after transplantation (< 6 h), severe PGD was differentiable from low PGD with an AUROC of 0.90 and an accuracy of 0.83 on test set samples. The model was somewhat effective for later time points with an AUROC of 0.80. Three major chemical classes in the model were dominated by alkylated hydrocarbons, linear hydrocarbons, and aldehydes in severe PGD samples. These VOCs may have important clinical and mechanistic implications, therefore large-scale study and potential translation to breath analysis is recommended.

RESUMO

Despite the demonstrated effectiveness of vaccines, varying levels of hesitancy were observed among healthcare and long-term care workers, who were prioritized in the roll out of COVID-19 vaccines due to their high risk of exposure to SARS-CoV-2 transmission. However, the evidence around the measurable impact of various educational interventions to improve vaccine confidence is limited. The proposed scoping review is intended to explore any emerging research and experiences of delivering educational interventions to improve COVID-19 vaccine confidence among health and long-term care workforces. We aim to identify characteristics of both informal and formal educational interventions delivered during the pandemic to support COVID-19 vaccine hesitancy. Using the guidance outlined by the Joanna Briggs Institute, we intend to search five databases including, Ovid MEDLINE and Web of Science, as well as grey literature. We will consider all study designs and reports in an effort to include a breadth of sources to ensure our review will capture preliminary evidence, as well as more exploratory experiences of COVID-19 vaccine education delivery. Articles will be screened by three reviewers independently and the data will be charted, and results described narratively.

RESUMO

Canada's healthcare sector produces the third highest healthcare-related emissions per capita globally. However, Canada has no national strategy toward environmentally sustainable healthcare. Transforming Canada's health systems to be environmentally sustainable requires leadership from many stakeholders and collaboration between trainees and health leaders. This article provides an overview of student and trainee leadership among health-related fields in response to the climate crisis and highlights the formation of a trainee-led organization focused on building capacity among emerging leaders in healthcare. We share key lessons learned by this group that are essential for all leaders seeking to leverage interdisciplinary action toward sustainable health systems in Canada.
