Probing the Molecular and Macroscopic Structure of Solid Solutions by Dynamic Nuclear Polarization (DNP) Enhanced 13C and 15N Solid-State NMR Spectroscopy.

Crystallization is a widely used purification technique in the manufacture of active pharmaceutical ingredients (APIs) and precursor molecules. However, when impurities and desired compounds have similar molecular structures, separation by crystallization may become challenging. In such cases, some impurities may form crystalline solid solutions with the desired product during recrystallization. Understanding the molecular structure of these recrystallized solid solutions is crucial to devise methods for effective purification. Unfortunately, there are limited analytical techniques that provide insights into the molecular structure or spatial distribution of impurities that are incorporated within recrystallized products. In this study, we investigated model solid solutions formed by recrystallizing salicylic acid (SA) in the presence of anthranilic acid (AA). These two molecules are known to form crystalline solid solutions due to their similar molecular structures. To overcome challenges associated with the long 1H longitudinal relaxation times (T1(1H)) of SA and AA, we employed dynamic nuclear polarization (DNP) and 15N isotope enrichment to enable solid-state NMR experiments. Results of solid-state NMR experiments and DFT calculations revealed that SA and AA are homogeneously alloyed as a solid solution. Heteronuclear correlation (HETCOR) experiments and plane-wave DFT structural models provide further evidence of the molecular-level interactions between SA and AA. This research provides valuable insights into the molecular structure of recrystallized solid solutions, contributing to the development of effective purification strategies and an understanding of the physicochemical properties of solid solutions.

Applying self-determination theory to stem medical schools' clinical teacher sustainability crisis.

THE PROBLEM: Medical schools require highly skilled and committed clinical faculty to teach, assess, supervise and mentor students' clinical care. Medical education is facing a crisis in recruiting and sustaining these clinical teachers. Faced with multiple demands and responsibilities in fast-paced clinical environments, teachers may not have the time, resources or stamina to sustain these critical roles. Medical school leaders must commit to and provide structures and processes to attract, sustain and retain clinical teachers. CONCEPTUAL FRAMEWORK: The authors use the lens of self-determination theory to frame approaches to support teacher sustainability. Self-determination theory describes sources of human motivation. The theory and its evidence base characterise three human psychological needs: autonomy, competence, and relatedness. This theory can bridge individual psychological and institutional leadership perspectives to help medical school leaders anticipate and respond to their clinical teachers' needs. The authors propose three practical steps: practices to advance employee-centredness, processes to align individual and institutional values, and restructuring education to support clinical teachers' needs alongside student and patient needs. The authors describe limitations to this relational approach that focuses on leadership actions and consider individual agency as another key factor for sustainability. DISCUSSION: Medical school leaders can develop and apply theory-driven approaches to advance sustainability. Sustainability now and in the future requires careful attention to the needs of clinical teachers and to their relationships with and within medical schools.

Psychological safety and accountability in longitudinal integrated clerkships: a dual institution qualitative study.

BACKGROUND: Psychological safety and accountability are frameworks to describe relationships in the workplace. Psychological safety is a shared belief by members of a team that it is safe to take interpersonal risks. Accountability refers to being challenged and expected to meet expectations and goals. Psychological safety and accountability are supported by relational trust. Relational continuity is the educational construct underpinning longitudinal integrated clerkships. The workplace constructs of psychological safety and accountability may offer lenses to understand students' educational experiences in longitudinal integrated clerkships. METHODS: We performed a qualitative study of 9 years of longitudinal integrated clerkship graduates from two regionally diverse programs-at Harvard Medical School and the University of North Carolina School of Medicine. We used deductive content analysis to characterize psychological safety and accountability from semi-structured interviews of longitudinal integrated clerkship graduates. RESULTS: Analysis of 20 graduates' interview transcripts reached saturation. We identified 109 discrete excerpts describing psychological safety, accountability, or both. Excerpts with high psychological safety described trusting relationships and safe learning spaces. Low psychological safety included fear and frustration and perceptions of stressful learning environments. Excerpts characterizing high accountability involved increased learning and responsibility toward patients. Low accountability included students not feeling challenged. Graduates' descriptions with both high psychological safety and high accountability characterized optimized learning and performance. CONCLUSIONS: This study used the workplace-based frameworks of psychological safety and accountability to explore qualitatively longitudinal integrated clerkship graduates' experiences as students. Graduates described high and low psychological safety and accountability. Graduates' descriptions of high psychological safety and accountability involved positive learning experiences and responsibility toward patients. The relational lenses of psychological safety and accountability may inform faculty development and future educational research in clinical medical education.

Preliminary Workforce Outcomes of an Urban Longitudinal Integrated Clerkship.

PURPOSE: The authors examined whether students participating in an urban longitudinal integrated clerkship (LIC) with a curriculum focused on care for underserved populations have a sustained commitment to urban underserved care through residency training and into practice. METHOD: This mixed-methods study collected data from medical student application essays to the Denver Health LIC (DH-LIC), end-of-course surveys, residency match outcomes, and postgraduation surveys annually for academic years 2014 to 2022. The authors analyzed students' responses to the surveys on interest in working with underserved patients, understanding the rewards and challenges of working in safety net institutions, working in the community to improve health, and working at DH. The authors qualitatively coded the 70 application essays of all selected students using summative content analysis. RESULTS: Seventy DH-LIC students were compared with 1,450 medical students between 2014 and 2022. Qualitative analysis of LIC application essays revealed 3 themes: interest in working with underserved populations, work experience with underserved populations, and personal experience with medical vulnerability. Fifty-seven DH-LIC participants (81.4%) expressed high levels of career interest in working with underserved populations, 45 (64.3%) had high levels of work experience with underserved populations, and 18 (25.7%) expressed high levels of personal experience. Graduates of the DH-LIC program demonstrated a high degree of continuing interest in practicing in urban underserved settings throughout medical school and postgraduate training. Ten graduates (71.4%) in practice work in urban underserved settings. Participants reported a high or very high level of interest and commitment to working with underserved populations (96.7%-100%), understanding the safety net health care system (91.7%-98.6%), and working in communities (95.0%-100%) at all time points studied. CONCLUSIONS: Early data indicate high rates of graduates working in urban underserved settings. These preliminary outcomes suggest the LIC may support the development of a committed workforce for urban underserved communities.

An exploratory study of goal orientations of traditional block and longitudinal integrated clerkship students.

BACKGROUND: Achievement goal theory links goal setting, motivation, and learning and describes three orientations: 'mastery' (seeking learning), 'performance' (seeking positive judgments), and 'performance-avoidance' (avoiding negative judgments). Mastery orientation is considered most adaptive. The authors investigated goal orientations of traditional block clerkship (TBC) and longitudinal integrated clerkship (LIC) students. METHODS: This was an exploratory study conducted at one US medical school. Three hundred and twenty students completed an anonymous survey consisting of three tools with validation evidence: Patterns of Adaptive Learning Survey, Task-choice Goal Measures, and Questionnaire Goal Choice Items. The authors analyzed the data using regression analyses, Chi-square, and Wilcoxon's rank-sum tests. RESULTS: While all students rated mastery items most highly on the five-point Likert scale (mean 4.58/5.00), LIC students rated performance-orientation lower (ß = -0.36, p = .04), chose personal mastery-orientation items more frequently (92% vs. 64.4%, p = .005), and perceived their learning environment as promoting less performance (ß = -0.60, p = .002) and performance-avoidance (ß = -0.78, p < .001) compared to TBC students. CONCLUSIONS: LIC and TBC students differed in their report of personal and clerkship goal orientations. These differences may inform educational design and future research to promote students' mastery orientation.

Patient outcomes in a Longitudinal Integrated Clerkship: A systematic literature review.

CONTEXT: Patient-student relationships are at the heart of Longitudinal Integrated Clerkships (LICs). Outcomes for students and preceptors are beneficial, but patient outcomes remain unclear. This systematic literature review explored the current evidence base of patient outcomes in an LIC. Patient outcomes were defined as issues related to patient safety, clinical effectiveness or patient experience. METHODS: Seven bibliographic databases were searched. A wider search strategy included a hand search of three medical education journals' previous issues and backward/forward citation searching of included studies and of a relevant systematic review. Included studies were quality appraised and assessed for their strength and level of evidence. A qualitative data synthesis was performed. RESULTS: Databases searches identified 7237 titles. Following the removal of duplicates, titles and abstracts were reviewed against the inclusion criteria. Forty-eight studies had a full-text review. Nineteen met the inclusion criteria. Seven studies were included from the wider search strategy. From the 26 included studies, two major themes were identified. (1) 'A trusting patient-student relationship' contains the sub-themes: 'care and compassion', 'patient education and empowerment' and 'the loss of the student as 'my' doctor'. (2) 'The student acts as an agent of change for the patient' contains the sub-themes: 'patient advocacy', 'supporting the patient to navigate the healthcare system', 'communication between patient and healthcare professional' and 'enhancement of preceptors' care, healthcare services and communities'. CONCLUSIONS: LICs provide educational continuity allowing the creation of a trusting patient-student relationship. This relationship leads to students becoming agents of change for patients by enhancing patient outcomes. This review provides further evidence on the benefits of having an LIC as part of the medical education curricula and implications for its successful delivery. Further research is needed to explore educationally induced benefits for patients and look at objective assessments of patient health outcomes.

Hydrates of active pharmaceutical ingredients: A 35Cl and 2H solid-state NMR and DFT study.

This study uses 35Cl and 2H solid-state NMR (SSNMR) spectroscopy and dispersion-corrected plane-wave density functional theory (DFT) calculations to characterize the molecular-level structures and dynamics of hydrates of active pharmaceutical ingredients (APIs). We use 35Cl SSNMR to measure the EFG tensors of the chloride ions to characterize hydrated forms of hydrochloride salts of APIs, along with two corresponding anhydrous forms. DFT calculations are used to refine the crystal structures of the APIs and determine relationships between the 35Cl EFG tensors and the spatial arrangements of proximate hydrogen bonds, which are particularly influenced by interactions with water molecules. We find that the relationship between 35Cl EFG tensors and local hydrogen bonding geometries is complex, but meaningful structure/property relationships can be garnered through use of DFT calculations. Specifically, for every case in which such a comparison could be made, we find that the hydrate has a smaller magnitude of CQ than the corresponding anhydrous form, indicating a chloride ion environment with a ground-state electron density of higher spherical symmetry in the former. Finally, variable-temperature 35Cl and 2H SSNMR experiments on a deuterium-exchanged sample of the API cimetidine hydrochloride monohydrate are used to monitor temperature-dependent influences on the spectra that may arise from motional influences on the 35Cl and 2H EFG tensors. From the 2H SSNMR spectra, we determine that the motions of water molecules are characterized by jump-like motions about their C2 rotational axes that occur on timescales that are unlikely to influence the 35Cl central-transition (+1/2 ↔︎ -1/2) powder patterns (this is confirmed by 35Cl SSNMR). Together, these methods show great promise for the future study of APIs in their bulk and dosage forms, especially variable hydrates in which crystallographic water content varies with external conditions such as humidity.

Faculty perspectives on facilitating medical students' longitudinal learning: A mixed-methods study.

INTRODUCTION: Medical students' longitudinal care of patients supports clinical learning and promotes patient-centredness. The literature presents little empirically derived guidance for faculty to facilitate students' longitudinal learning and care. Informed by the conceptual framework of relational learning, this study investigated faculty perspectives about longitudinal teaching, their strategies for facilitating students' longitudinal learning and perceived barriers and enablers. METHODS: Using a convergent mixed-methods approach at a single academic medical centre, the authors conducted a survey and two focus groups in 2018-2019 with faculty members teaching in three longitudinal clinical courses. Quantitative analyses included descriptive statistics and chi-square tests. Qualitative content analysis described deductive categories and identified inductive themes. RESULTS: Forty-three eligible faculty (69%) completed the survey. Ninety-one percent (n = 39) reported that teaching in a longitudinal model enhanced their experience as preceptors. Faculty described activities students performed to provide longitudinal care: spending time with patients independently (n = 38, 88%), making follow-up phone calls (n = 35; 81%) and participating in home- and community-based visits (n = 20, 47%), among others. Twelve faculty participated in two focus groups. Deductive analysis characterised strategies for facilitating students' longitudinal learning and barriers and enablers. Strategies included "encouraging students to follow patients," "faculty adaptability," "offering guidance and setting expectations," and "careful patient selection." Barriers included scheduling limitations, and enablers included student initiative. Inductive analysis identified two themes: faculty goals for students and faculty benefits from teaching. Goals included meaningful engagement with patients and their illness over time. Benefits from teaching included personal gratification, mentorship, and holistic student assessment. DISCUSSION: Our survey and focus group findings demonstrated positive faculty attitudes and experiences, characterised faculty goals and approaches, and identified elements of the educational context that hindered or facilitated longitudinal teaching and learning. This study's faculty perspectives build upon prior investigations of students' and patients' perspectives, offer teaching strategies, and may guide faculty development.

Enhancing the one-minute preceptor method for clinical teaching with a DEFT approach.

Few validated methods that are grounded in educational theory exist to effectively teach medical knowledge, clinical skills, and diagnostic reasoning to learners at different stages of medical training. The goal of this Perspective was to address potential gaps in clinical education pedagogy by modeling new concepts for teaching in the field of infectious diseases. Our approach involved synthesizing the relevant literature, identifying proven approaches, and enhancing an existing educational microskills model - the one-minute preceptor. Our strategy was to emphasize the essential core elements of the one-minute preceptor using a descriptive acronym - DEFT (Diagnosis, Evidence, Feedback, Teaching), meaning skillful - as a potentially helpful reminder to improve the quality of interactions between learners and preceptors. The need for learners to discuss risk factors, mechanisms of disease, and potential complications, and for preceptors to model analytical and diagnostic skills, was further illustrated using a practical example of a teacher-learner interaction about a child with a respiratory infection. The one-minute preceptor/DEFT approach is experiential, adaptable, case-driven, and skills-focused, and also applicable to clinical training in other specialties.

A Trauma-Informed Approach to the Medical History: Teaching Trauma-Informed Communication Skills to First-Year Medical and Dental Students.

Introduction: Trauma is ubiquitous and associated with negative effects on physical and mental health. Trauma-informed care (TIC) is a framework for mitigating these health effects and improving patients' engagement with medical care. Despite these clinical benefits, TIC is not routinely taught in undergraduate medical education. Methods: We designed a session for first-year medical and dental students to introduce TIC principles and their application in patient care. The session focused on screening for and inquiring about trauma and responding to disclosures of trauma. Using live patient interviews, small-group discussions, and case-based role-plays, the session offered expert instruction and hands-on practice. Students completed pre- and postsession surveys and a 5-month follow-up survey. Students reported their comfort with screening for trauma and responding to disclosures of trauma before and after the session and at 5 months following the session. Results: Of the 164 student participants, 76% completed surveys during the session, and 50% completed the follow-up survey. More than one-third (34%) of respondents reported having received at least one disclosure of trauma from a patient within the first 5 months of medical school. Students' comfort with screening for trauma increased from 30% to 56%, and their comfort with responding to disclosure of trauma increased from 35% to 55%. These improvements persisted on reevaluation at 5 months. Discussion: We present a model for teaching trauma-informed communication skills to first-year medical and dental students. The intervention significantly increased students' comfort level and self-reported clinical skills, and benefits persisted at 5 months.

Coproducing clinical curricula in undergraduate medical education: Student and faculty experiences in longitudinal integrated clerkships.

PURPOSE: Educational coproduction, in which learners partner with educators to create and improve their educational experiences, can facilitate student-centered medical education. Empirical descriptions of best practices for involving students in clinical curricular coproduction are needed. We aimed to understand faculty and student perspectives on methods, perceived benefits, and common barriers and solutions to clinical curricular coproduction. METHODS: We conducted an international mixed-methods study of clinical curricular coproduction in undergraduate medical education and longitudinal integrated clerkships specifically. Faculty and students identified through an international listserv received an electronic survey to identify methods, benefits, and challenges of clinical curricular coproduction. We conducted semi-structured interviews with a subset of survey participants. We present descriptive statistics for survey data and themes derived from inductive qualitative analysis. RESULTS: Two hundred forty-seven individuals (104 faculty; 143 students) representing 52 medical schools in eight countries completed the survey. Methods for clinical curricular coproduction ranged from informal, low-intensity learner involvement (e.g. verbal feedback) to formal, high-intensity learner involvement (e.g. committee membership). Perceived benefits included improvements in student-faculty relationships, program culture and design, and student development. Structural issues (e.g. scheduling) were the most common perceived barriers. CONCLUSIONS: Clinical curricular coproduction among faculty and students is perceived to enhance collaboration, enable curriculum change, and support students' professional development. Our study offers empirical guidance for involving students as partners in clinical curricular coproduction.

Patient perceptions of students in a longitudinal integrated clerkship in Taiwan: a qualitative study.

BACKGROUND: Longitudinal integrated clerkships (LICs) are a model of clinical education growing rapidly in Western contexts. LICs use educational continuity to benefits students' clinical learning and professional identity formation. Patient-centered care is a core component of medical professionalism in the West. To support patient-centered care, education leaders in Taiwan restructured clinical education and implemented the first longitudinal integrated clerkship in East Asia. We aimed to investigate patients' perceptions of longitudinal relationships with the LIC students within Taiwan's Confucian cultural and social context. METHODS: We invited patients or their family members who were cared for longitudinally by a LIC student to participate in the study. Participating patients or their family members undertook semi-structured interviews. We analyzed data qualitatively using a general inductive approach to identify themes in the patients' descriptions of their experiences interacting with the LIC students. RESULTS: Twenty-five patients and family members participated in interviews: 16 patients and 9 family members. Qualitative analysis of interview transcripts identified three themes from patients' experience receiving care from their LIC students: care facilitation, companionship, and empathy. To provide care facilitation, LIC students served as a bridge between the physicians and patients. Students served patients by reminding, consulting, tracking disease progression, and researching solutions for problems. To provide companionship, students accompanied patients interpersonally like a friend or confidant who listens and provides a presence for patients. To provide empathy, patients reported that students showed sincere concern for patients' experience, feelings, and mood. CONCLUSION: In our study, Taiwanese patients' perspectives of LIC students suggested the value of care facilitation, companionship, and empathy. We discuss these themes within the context of Confucian culture and the Taiwanese context of care.

Everyday Resilience: Equipping Faculty With Practical Exercises to Promote Resilience Among Medical Students.

Introduction: Burnout is prevalent in health care. As professionals advocate to increase resilience training as a strategy to reduce burnout, few examples exist of practical resilience programs that equip faculty to help students build and sustain well-being over time. Method: We developed two straightforward, skills-based resilience exercises. Breaking Down Easy taught individuals to identify personal strengths. My Resilience Practice helped individuals identify strategies to cope with daily stressors. We taught these exercises to international faculty in a train-the-trainer workshop format, at two medical education conferences. Faculty applied the exercises, performed pair-share reflections, and discussed opportunities to introduce the exercises in their own institutions. Postsession surveys evaluated the workshop quality and the exercises' ease of use and applicability. Results: Thirty-five faculty and five students participated across two international conferences. Of participants, 83% (33 of 40) completed postsession surveys. On a 5-point Likert scale, participants rated the workshop on average 4.4 for usefulness, 4.6 for applicability, 4.4 for ease of instruction, 4.5 for clarity, and 4.8 for overall quality. Participants found the exercises to be straightforward to use and planned to use them at their institutions with students, residents, and faculty. Discussion: Participants found our workshop to be relevant and effective and shared their intention to incorporate these materials into their teaching with medical students, residents, and faculty. Implementing effective programs to build resilience is critical to increasing well-being and reducing burnout. This, in turn, may enhance patient safety and improve health system outcomes.

Trauma-Informed Medical Education (TIME): Advancing Curricular Content and Educational Context.

The majority of patients and medical students experience some form of psychological trauma or adversity across their life course. All forms of trauma can be associated with adverse health consequences and can negatively affect learning and professional development. Trauma-informed care (TIC) offers a framework to address and mitigate these consequences and promote safety and health. The Substance Abuse and Mental Health Services Administration describes 6 domains of TIC: safety; trust and transparency; peer support; collaboration and mutuality; empowerment, voice, and choice; and cultural, historic, and gender issues. At present, TIC is not taught routinely in undergraduate medical education (UME)-a crucial educational gap given that UME grounds the development of key perspectives and practices that students use throughout their careers. Further, given the prevalence of preexisting trauma among learners and the likelihood of new traumatic exposures during training, medical schools' processes, practices, and learning environments may risk exacerbating or even causing trauma. To address this educational need and support students and their future patients, the authors propose a trauma-informed medical education (TIME) framework. TIME informs medical schools' curricular content and educational context. In UME, curricular content should address trauma epidemiology, physiology, and effects; trauma-informed clinical skills including sensitive communication and physical exam techniques; and trauma-informed self-care techniques including education on organizational resources, how to elicit supports, and personal self-care practices. A trauma-informed educational context encompasses curricular development, including student-faculty coproduction of educational content; curricular delivery, including faculty development on TIC principles; and learning environment, including trauma-informed educational practices, medical student advising, institutional policies, and recruitment. TIME offers practical strategies to support teaching, learning, educational administration, and professional development and aims to inspire new strategies for effective learner and faculty engagement. TIME aims to foster students' development of competency in TIC and promote student engagement, learning, health, and well-being.
