Designing a Multidisciplinary Cardio-obstetrics Curriculum for General Cardiology and Obstetrics Residents: A National Survey of Educational Needs.

Background: The increasing and potentially preventable cardiac events in pregnant patients have led to calls to enhance multidisciplinary cardio-obstetrics education. To design a multidisciplinary cardio-obstetrics curriculum for general cardiology and obstetrics and gynecology (OBGYN) residents, we need to define educational needs from the perspectives of both cardiology and OBGYN residents. Our study characterizes the educational needs of Canadian cardiology and OBGYN residents. Methods: Canadian cardiology and OBGYN residents were surveyed on clinical exposures, perceived needs for topics, unperceived needs for topics (multiple-choice questions) and preferences for educational formats. High priorities were defined as ≥ 50% of responses indicating a perceived need or ≥ 50% indicating an unperceived need. Results: A total of 154 residents participated (cardiology n = 44, OBGYN n = 110). Residents reported insufficient clinical exposure to nearly all cardiac disorders, with 33% of exposures occurring in multidisciplinary contexts. All topics aside from gestational hypertension were rated as high priority on perceived needs by both specialties. High-priority unperceived needs were congenital heart disease (both specialties), pre-existing acquired heart disease (both specialties), medication safety (OBGYN), peripartum management (OBGYN), and pregnancy-related heart disease (OBGYN). Cardiology and OBGYN residents shared preferences for in-person simulation, virtual simulation, and online modules. Conclusions: Residents in both specialties reported low clinical exposure to most cardiac disorders during pregnancy, identified high-priority perceived needs in multiple topics, and shared 2 high-priority unperceived needs. OBGYN residents identified 3 additional high-priority unperceived needs. These data can inform design of multidisciplinary cardio-obstetrics curricula for general cardiology and OBGYN residents.

Contexte: L'augmentation du nombre d'événements cardiaques potentiellement évitables chez les patientes enceintes a conduit à des appels pour renforcer la formation multidisciplinaire en cardio-obstétrique. Afin de concevoir un programme d'études multidisciplinaires en cardio-obstétrique pour les résidents en cardiologie générale et en obstétrique et gynécologie (OBGYN), nous devons définir les besoins éducatifs du point de vue des résidents en cardiologie et en OBGYN. Notre étude caractérise les besoins éducatifs des résidents canadiens en cardiologie et en OBGYN. Méthodes: Les résidents canadiens en cardiologie et en OBGYN ont été interrogés sur leurs expositions cliniques, les besoins perçus et non perçus en matière de thématique à aborder (questions à choix multiples) et leurs préférences en matière de formats éducatifs. Les priorités élevées ont été définies comme représentant ≥ 50 % des réponses indiquant un besoin perçu ou ≥ 50 % indiquant un besoin non perçu. Résultats: Cent cinquante-quatre résidents ont participé (cardiologie n = 44, OBGYN n = 110). Les résidents ont signalé une exposition clinique insuffisante pour presque tous les troubles cardiaques, 33 % des expositions se produisant dans des contextes multidisciplinaires. Toutes les thématiques, à l'exception de l'hypertension gestationnelle, ont été jugées hautement prioritaires en ce qui concerne les besoins perçus par les deux spécialités. Les besoins non perçus comme hautement prioritaires comprenaient les cardiopathies congénitales (les deux spécialités), les cardiopathies acquises préexistantes (les deux spécialités), la sécurité des médicaments (OBGYN), la gestion du péripartum (OBGYN) et les cardiopathies liées à la grossesse (OBGYN). Les résidents en cardiologie et en OBGYN partageaient des préférences pour les simulations en personne, les simulations virtuelles et les modules de formation en ligne. Conclusions: Les résidents des deux spécialités ont rapporté une faible exposition clinique à la plupart des troubles cardiaques pendant la grossesse, ont identifié des besoins perçus comme hautement prioritaires dans plusieurs domaines, et ont partagé 2 besoins non perçus comme hautement prioritaires. Les résidents en OBGYN ont identifié 3 autres besoins non perçus comme hautement prioritaires. Ces données peuvent éclairer la conception de programmes d'études multidisciplinaires en cardio-obstétrique pour les résidents en cardiologie générale et en OBGYN.

How do residents respond to uncertainty with peers and supervisors in multidisciplinary teams? Insights from simulations with epistemic fidelity.

BACKGROUND: Residents struggle to express clinical uncertainty, often exhibiting negative cognitive, behavioral, and emotional responses to uncertainty when engaging with patients or supervisors. However, the Integrative Model of Uncertainty Tolerance posits that individuals may have positive or negative responses to perceived uncertainty. Situational characteristics, such as interactions with other health professionals, can impact whether the response is positive or negative. The team context in which residents interact with resident peers and supervisors could represent varying situational characteristics that enable a spectrum of responses to uncertainty. Understanding the situational characteristics of multidisciplinary teams that allow residents to display positive responses to perceived uncertainty could inform strategies to foster positive responses to uncertainty in other contexts. We explored resident responses to perceived uncertainty in a simulated multidisciplinary team context. METHODS: A simulation-primed qualitative inquiry approach was used. Fourteen residents from Cardiology and Obstetrics and Gynecology participated in simulation scenarios involving pregnant patients with heart disease. We incorporated epistemic fidelity through the deliberate inclusion of ambiguity and complexity to prompt uncertainty. Audio recordings of debriefing sessions were analyzed using directed content analysis. RESULTS: Residents recognized that uncertainty is unavoidable, and positive responses to uncertainty are crucial to team dynamics and patient safety. While residents had positive responses to expressing uncertainty to peers, they had predominantly negative responses to expressing uncertainty to supervisors. Predominant negative response to supervisors related to judgement from supervisors, and impacts on perceived trustworthiness or independence. Although residents recognized expressing uncertainty to a supervisor could identify opportunities for learning and resolve their uncertainty, the negative responses overshadowed the positive responses. Residents highly valued instances in which supervisors were forthcoming about their own uncertainty. CONCLUSIONS: Through participation in simulations with epistemic fidelity, residents reflected on how they perceive and respond to uncertainty in multidisciplinary teams. Our findings emphasize the role of situational characteristics, particularly peers and supervisors, in moderating responses to perceived uncertainty. The productive discussions around responses to uncertainty in debriefing sessions suggest further studies of multidisciplinary simulations could enhance our understanding of how uncertainty is expressed, and potentially be used as an instructional intervention to promote positive responses to uncertainty.

"The patient is awake and we need to stay calm": reconsidering indirect communication in the face of medical error and professionalism lapses.

BACKGROUND: Although speaking up is lauded as a critical patient safety strategy, it remains exceptionally challenging for team members to enact. Existing efforts to address the problem of silence among interprofessional teams involve training low-authority members to use direct language and unambiguous challenge scripts. The role or value of indirect communication in preventing medical error remains largely unexplored despite its pervasiveness among interprofessional teams. This study explores the role of indirect challenges in the face of medical error and professionalism lapses. METHODS: Obstetricians at one academic center participated in an interprofessional simulation as a partial actor. Thirteen iterations were completed with 39 participants (13 obstetrician consultants, 11 obstetric residents, 2 family medicine consultants, 5 midwives, and 8 obstetrical nurses). Thirty participants completed a subsequent semi-structured interview. Five challenge moments were scripted for the obstetrician involving deliberate clinical judgment errors or professionalism infractions. Other participants were unaware of the obstetrician's partial actor role. Scenarios were videotaped; debriefs and interviews were audio-recorded and transcribed verbatim and analyzed using a constructivist qualitative approach. RESULTS: Low-authority team members primarily relied on indirect challenge scripts to promote patient safety during simulation. Faculty participants were highly receptive to indirect challenges from low-authority team members, particularly in front of awake patients. In the context of obstetric care, direct challenges were actually viewed by participants as threatening to patient trust and disruptive to the interprofessional team. Instead of exclusively focusing our efforts on encouraging low-authority team members to speak up through direct challenges, it may be fruitful to expand our attention toward teaching faculty to identify, listen for, and respond to the indirect, subtle challenges that are already prolific among interprofessional teams.

"Maybe I'm not that approachable": using simulation to elicit team leaders' perceptions of their role in facilitating speaking up behaviors.

BACKGROUND: Simulation research that seeks to solve the problem of silence among interprofessional teams has focused almost exclusively on training subordinate team members to be more courageous and to speak up to team leaders using direct challenge scripts despite the great interpersonal cost. Consequently, the existing literature overemphasizes the responsibility of subordinate team members for speaking up and fails to consider the role and responsibilities of team leaders in sustaining silence. The purpose of this study is to identify and describe the subtle behaviors and actions of team leaders that both promote and discourage speaking up. METHODS: This study used a simulation-primed qualitative inquiry approach. Obstetricians (OB) at one academic center participated in an interprofessional simulation as an embedded participant. Five challenge moments (CM) were scripted for the OB involving deliberate clinical judgment errors or professionalism infractions. Other participants were unaware of the OB embedded participant role. Thirteen iterations were completed with 39 participants. Twelve faculty members completed a subsequent semi-structured interview. Scenarios were videotaped; debriefs and interviews were audio-recorded and transcribed verbatim. Data were analyzed using an inductive thematic approach. RESULTS: After participating in an interprofessional simulation, faculty participants reflected that being an approachable team leader requires more than simply avoiding disruptive behaviors. We found that approachability necessitates that team leaders actively create the conditions in which team members perceive that speaking up is welcomed, rather than an act of bravery. In practice, this conceptualization of approachability involves the tangible actions of signaling availability through presence, uncertainty through thinking aloud, and vulnerability through debriefing. CONCLUSIONS: By using faculty as embedded participants with scripted errors, our simulation design provided an ideal learning opportunity to prompt discussion of the subtle behaviors and actions of team leaders that both promote and discourage speaking up. Faculty participants gained a new appreciation that their actions create the conditions for speaking up to occur before critical incidents through their verbal and non-verbal communication.

Myasthenia gravis in pregnancy: Systematic review and case series.

Background: Myasthenia gravis is an autoimmune disease which can impact pregnancy. Methods: Six databases were systematically searched for studies with at least five subjects reporting pregnancy outcomes for women with myasthenia gravis in pregnancy. Assessment of bias was performed for all included studies. Forty-eight cases from our own centre were also included in the analysis. Results: In total, 32 publications met inclusion criteria for systematic review, for a total of 33 unique data sets including 48 cases from our institution. Outcome data was available for 824 pregnancies. Spontaneous vaginal delivery occurred in 56.3% of pregnancies. Overall risk of myasthenia gravis exacerbation was 33.8% with a 6.4% risk of myasthenic crisis in pregnancy and 8.2% postpartum. The incidence risk of transient neonatal myasthenia gravis was 13.0%. Conclusions: The current systematic review provides the best estimates of risk currently available to aid in counselling women with myasthenia gravis in pregnancy.

The brain-derived neurotrophic factor Val66Met polymorphism is associated with reduced functional magnetic resonance imaging activity in the hippocampus and increased use of caudate nucleus-dependent strategies in a human virtual navigation task.

Multiple memory systems are involved in parallel processing of spatial information during navigation. A series of studies have distinguished between hippocampus-dependent 'spatial' navigation, which relies on knowledge of the relationship between landmarks in one's environment to build a cognitive map, and habit-based 'response' learning, which requires the memorization of a series of actions and is mediated by the caudate nucleus. Studies have demonstrated that people spontaneously use one of these two alternative navigational strategies with almost equal frequency to solve a given navigation task, and that strategy correlates with functional magnetic resonance imaging (fMRI) activity and grey matter density. Although there is evidence for experience modulating grey matter in the hippocampus, genetic contributions may also play an important role in the hippocampus and caudate nucleus. Recently, the Val66Met polymorphism of the brain-derived neurotrophic factor (BDNF) gene has emerged as a possible inhibitor of hippocampal function. We have investigated the role of the BDNF Val66Met polymorphism on virtual navigation behaviour and brain activation during an fMRI navigation task. Our results demonstrate a genetic contribution to spontaneous strategies, where 'Met' carriers use a response strategy more frequently than individuals homozygous for the 'Val' allele. Additionally, we found increased hippocampal activation in the Val group relative to the Met group during performance of a virtual navigation task. Our results support the idea that the BDNF gene with the Val66Met polymorphism is a novel candidate gene involved in determining spontaneous strategies during navigation behaviour.

Caudate nucleus-dependent response strategies in a virtual navigation task are associated with lower basal cortisol and impaired episodic memory.

The present research examined the relationship between endogenous glucocorticoids, navigational strategies in a virtual navigation task, and performance on standard neuropsychological assessments of memory. Healthy young adult participants (N=66, mean age: 21.7) were tested on the 4 on 8 virtual maze (4/8 VM) and standard neuropsychological tests such as the Rey-Osterrieth Complex Figure (RO) and the Rey Auditory Verbal Learning Task (RAVLT), which measure episodic memory. The 4/8 VM differentiates between navigational strategies, where participants either use a hippocampal-dependent spatial strategy by building relationships between landmarks, or a caudate nucleus-dependent stimulus-response strategy by automatizing a pattern of open and closed arms to learn the location of objects within the maze. Degree of stress was assessed by administering the Perceived Stress Scale (PSS) questionnaire. Cortisol samples were taken on two consecutive days upon waking, 30 min after waking, at 11 am, 4 pm, and 9 pm. There was a significant difference in basal levels of cortisol between spatial and response learners. Interestingly, response learners had significantly lower cortisol levels throughout the day. The two groups did not differ in terms of perceived stress as measured with the PSS questionnaire. Moreover, there was no significant correlation between PSS scores and salivary cortisol levels, indicating that the higher cortisol levels in the spatial group were not associated with greater perceived stress. In addition, participants who spontaneously used a spatial strategy performed significantly better on the RAVLT and RO. These data indicate that the cortisol levels in the spatial group may be optimal in terms of episodic memory performance whereas the cortisol levels in the response group may be associated with poorer memory. These results are suggestive of an inverted U-shaped curve describing the effects of basal levels of circulating cortisol on memory in young adults.

Towards an evidence-based approach to optimize the success of labour induction.

Induction of labour is a two-step process involving cervical ripening and the initiation of uterine contractions, with the goal of achieving vaginal birth. To optimize the chance of a safe and timely vaginal birth, the process of induction of labour should be evidence based and individualized to the given person and situation. In this study, we lay out a framework for how this should be done, emphasizing on careful clinical assessment and planning, flexibility in the strategy of induction, patience during the ripening and latent phases of labour, and thoughtful consideration regarding changing the strategy if active labour is not initially achieved. The goal of this review is to present the current evidence on this topic in the form of a user-friendly protocol that can be easily adapted to institutional practice.

APOE2 Is Associated with Spatial Navigational Strategies and Increased Gray Matter in the Hippocampus.

The Apolipoprotein E (APOE) gene has a strong association with Alzheimer's disease (AD). The ε4 allele is a well-documented genetic risk factor of AD. In contrast, the ε2 allele of the APOE gene is known to be protective against AD. Much of the focus on the APOE gene has been on the ε4 allele in both young and older adults and few studies have looked into the cognitive and brain structure correlates of the ε2 allele, especially in young adults. In the current study, we investigated the relationship between APOE genotype, navigation behavior, and hippocampal gray matter in healthy young adults. One-hundred and twenty-four healthy young adults were genotyped and tested on the 4on8 virtual maze, a task that allows for the assessment of navigation strategy. The task assesses the spontaneous use of either a hippocampus-dependent spatial strategy or a caudate nucleus-dependent response strategy. Of the 124 participants, 37 underwent structural magnetic resonance imaging (MRI). We found that ε2 carriers use a hippocampus-dependent spatial strategy to a greater extent than ε3 homozygous individuals and ε4 carriers. We also found that APOE ε2 allele carriers have more gray matter in the hippocampus compared to ε3 homozygous individuals and ε4 carriers. Our findings suggest that the protective effects of the ε2 allele may, in part, be expressed through increased hippocampus gray matter and increased use of hippocampus-dependent spatial strategies. The current article demonstrates the relationship between brain structure, navigation behavior, and APOE genotypes in healthy young adults.
