Medical student exam performance and perceptions of a COVID-19 pandemic-appropriate pre-clerkship medical physiology and pathophysiology curriculum.

BACKGROUND: Medical schools were compelled to abruptly transition pre-clerkship curricula to remote learning formats due to the emergence of the Coronavirus Disease 2019 (COVID-19) pandemic. We evaluated student perceptions of remote learning, exam performance, and utilization of third-party learning resources to assess the implementation of a newly developed pandemic-appropriate physiology curriculum. METHODS: This was an observational study based on a survey conducted in the Spring of 2021 at the University of California, Irvine, School of Medicine (UCISOM). This study aimed to assess first (MS1) and second year (MS2) medical students' perceptions of satisfaction, support, academic performance, and connectedness before and during the COVID-19 pandemic. The MS1 class began medical school during the first year of the COVID-19 pandemic, whereas the MS2 class did so prior to the start of the pandemic. A survey instrument was developed and validated to identify the impact remote learning had on student self-perceptions of the Medical Physiology and Pathophysiology course. Surveys were distributed to all students and responses were collected on a voluntary basis. Exam scores on a customized National Board of Medical Examiners (NBME) physiology shelf exam were also compared to objectively identify how the remote curriculum during the pandemic impacted academic performance. RESULTS: Of 204 students enrolled, 74 responses were analyzed, with 42 MS1 (40% of MS1s) and 32 MS2 (31% of MS2s) responses. Overall, MS1s and MS2s were satisfied with the curriculum they received (95 and 97% respectively) and the school's support of their concerns (86 and 100% respectively). Notably, only 50% of MS1s felt connected to their peers, compared to 94% of MS2s. Lecture attendance and self-perception of their academic performance were similar between both classes. Interestingly, the intra-pandemic class's NBME exam average in 2020 (60.2% ± 8.9, n = 104) was significantly higher than the pre-pandemic class average in 2019 (56.8% ± 11.3, n = 100). Both classes primarily used course materials over third-party learning resources. An additional set of survey questions distributed only to the MS1 class found that the majority of MS1s reported minimal barriers with regards to accessibility, including internet connectivity, study-conducive environments, and balancing family commitments. Overall, pre-clerkship medical students had positive perceptions of the newly developed pandemic-appropriate physiology curriculum. CONCLUSIONS: Changes to the pre-clerkship physiology curriculum during the COVID-19 pandemic were met with overall satisfaction from the students and an increase in NBME scores. More attention to student connectedness is needed to improve how remote learning can be best optimized into future curricula development.

Prevalence of financial hardship and health-related social needs among patients with missed radiology appointments.

PURPOSE: We aimed to evaluate the prevalence of financial hardship and Health-Related Social Needs (HRSN) among patients who missed their radiology appointment. METHODS: English-speaking adult patients, with a missed outpatient imaging appointment at any of a tertiary care imaging centers between 11/2022 and 05/2023 were eligible. We measured self-reported general financial worry using Comprehensive Score for Financial Toxicity (COST), imaging hardship (worry that the current imaging is a financial hardship to patient and their family), material hardship (e.g., medical debt), cost-related care nonadherence, and HRSNs including housing instability, food insecurity, transportation problems, and utility help needs. RESULTS: 282 patients were included (mean age 54.7 ± 15.0 years; 70.7 % female). Majority were non-Hispanic White (52.4 %), followed by Asian (23.0 %) and Hispanic (16.0 %) racial/ethnic background. Most missed appointments were patient-initiated (74.8 %); 13.5 % due to cost or insurance coverage and 6.4 % due to transportation and parking. Mean COST score was 26.8 with 44.4 % and 28.8 % reporting their illness and imaging as a source of financial hardship. 18.3 % and 35.2 % endorsed cost-related care nonadherence and material hardship. 32.7 % had at least one HRSNs with food insecurity the most common (25.4 %). Only 12.5 % were previously screened for financial hardship or HRSNs. Having comorbidity and living in more disadvantaged neighborhoods was associated with higher report of financial hardship and HRSNs. CONCLUSION: Financial hardship and HRSNs are common among those who miss radiology appointments. There needs to be more rigorous screening for financial hardship and HRSNs at every health encounter and interventions should be implemented to address these.

Feasibility of Screening for Financial Hardship and Health-Related Social Needs at Radiology Encounters.

OBJECTIVE: To evaluate the prevalence of financial hardship and health-related social needs (HRSNs) among outpatients undergoing advanced imaging services and assess the feasibility of screening for financial and social needs during radiology encounters. METHODS: Adult patients receiving CT, MRI, or PET/CT at outpatient imaging centers of an academic tertiary center were asked to complete a 15-minute survey with adapted validated questions inquiring about their experience of financial hardship related to imaging and HRSNs, and the appropriateness of screening for financial and social needs at radiology encounters. Logistic regression analyses were performed to assess factors associated with perceived appropriateness of screening and level of interest in meeting with financial counselors. RESULTS: A total of 430 patients responded (10.0% response rate; mean age: 57.1 years; 57.4% female; 54.5% White; 22.1% Hispanic; 19.1% Asian; 1% Black). A total of 35% reported experiencing financial hardship with imaging; 47.5% reported material hardship, 15.3% reported cost-related care nonadherence, and 5.3% reported cost-related imaging nonadherence. Overall, 35.9% had at least one HRSN, with food insecurity being the most common (28.3%). The majority (79.7%) felt that being screened for HRSNs at radiology encounters is appropriate, with those experiencing imaging hardship being more likely to feel that screening is appropriate (odds ratio [OR]: 2.93; 95% confidence interval [CI], 1.31-6.56). Overall, 29.5% were interested in meeting with a financial counselor, with those with imaging hardship (OR: 3.70; 95% CI, 1.96-6.97) and HRSNs (OR: 2.87; 95% CI, 1.32-6.24) and who felt uncomfortable with screening (OR: 2.83; 95% CI, 1.14-7.03) being more likely to be interested. DISCUSSION: Financial hardship and HRSNs are common among outpatients undergoing advanced imaging, with the majority reporting that getting screened at radiology encounters is appropriate.

Collaborative Learning Communities With Medical Students as Teachers.

In recent years, peer-assisted learning has emerged as a new and effective medical education modality. Near-peer tutoring utilizes a senior student serving as an instructor to a junior student. In 2019, the University of California, Irvine, School of Medicine (UCISOM) implemented a near-peer tutoring model beginning with first-year anatomy and physiology curricula. Following a successful pilot program, UCISOM launched a full-fledged near-peer tutoring program in 2020 named Collaborative Learning Communities (CLC) with Medical Students as Teachers. The rollout of CLC occurred in phases. In 2020, second-year medical students led the program for first-year students; in 2021, an additional program was led by third-year medical students for second-year students; in 2022, the program expanded to third-year medical students led by fourth-year students. Each program serves the unique learning needs of each student class, utilizing evidence-based teaching practices while allowing the opportunity for mentorship, interclass connectedness, and refinement of the tutor's teaching skills. In this paper, we describe the creation of CLC, its goals, leadership and curricular structure, and its various benefits, challenges, and limitations.

Redesigning TOR Kinase to Explore the Structural Basis for TORC1 and TORC2 Assembly.

TOR is a serine/threonine protein kinase that assembles into distinct TOR Complexes 1 and 2 (TORC1 or TORC2) to regulate cell growth. In mammalian cells, a single mTOR incorporates stably into mTORC1 and mTORC2. By contrast, in Saccharomyces cerevisiae, two highly similar Tor1 and Tor2 proteins exist, where Tor1 assembles exclusively into TORC1 and Tor2 assembles preferentially into TORC2. To gain insight into TOR complex assembly, we used this bifurcation in yeast to identify structural elements within Tor1 and Tor2 that govern their complex specificity. We have identified a concise region of ~500 amino acids within the N-terminus of Tor2, which we term the Major Assembly Specificity (MAS) domain, that is sufficient to confer significant TORC2 activity when placed into an otherwise Tor1 protein. Consistently, introduction of the corresponding MAS domain from Tor1 into an otherwise Tor2 is sufficient to confer stable association with TORC1-specific components. Remarkably, much like mTOR, this latter chimera also retains stable interactions with TORC2 components, indicating that determinants throughout Tor1/Tor2 contribute to complex specificity. Our findings are in excellent agreement with recent ultrastructural studies of TORC1 and TORC2, where the MAS domain is involved in quaternary interactions important for complex formation and/or stability.
