Bridging Gaps in Collaboration Between Community Organizations and Hospital-Based Violence Treatment Centers Serving Transgender Sexual Assault Survivors.

Community and healthcare organizations have not historically collaborated effectively, leaving gaps in the continuum of care for survivors of sexual assault. These gaps are particularly acutely felt by transgender (trans) survivors, who experience additional barriers to care and face higher rates of sexual assault. To bridge these gaps and enhance the provision of comprehensive support for trans people, we developed an intersectoral network of trans-positive community and hospital-based organizations in Ontario, Canada. As part of a baseline evaluation of the network, we conducted a social network analysis to determine the extent and nature of collaboration between members within and across these two sectors. Using a validated social network analysis tool (PARTNER survey), data were collected from June 22 to July 22, 2021. The extent of collaboration was examined by relationship type: intrasectoral (same sector) and intersectoral (different sectors). The nature of collaboration was examined using relational scores (value: power, level of involvement, potential resource contribution; trust: reliability, mission congruence, openness to discussion). Fifty-four community organizations (65.9% of 82 invited) and 24 hospital-based violence treatment centers (64.9% of 37 invited) responded. The majority of collaborations were within, rather than across, the two sectors: of all 378 collaborations described, 70.9% (n = 268) were intrasectoral collaborations and 29.1% (n = 110) were intersectoral collaborations. Intersectoral relationships were characterized by lower scores for level of involvement, trust, reliability, and mission congruence than intrasectoral relationships, but higher scores for power. These findings were shared in a virtual consultation session of key stakeholders, in which some participants expressed "surprise" and concern for the lack of collaboration and character of relationships across sectors. Recommendations to increase intersectoral collaboration, which included intersectoral program planning and service design and supporting increased opportunities for intersectoral training and knowledge exchange, are presented.

MceG stabilizes the Mce1 and Mce4 transporters in Mycobacterium tuberculosis.

Lipids are important nutrients for Mycobacterium tuberculosis (Mtb) to support bacterial survival in mammalian tissues and host cells. Fatty acids and cholesterol are imported across the Mtb cell wall via the dedicated Mce1 and Mce4 transporters, respectively. It is thought that the Mce1 and Mce4 transporters are comprised of subunits that confer substrate specificity and proteins that couple lipid transport to ATP hydrolysis, similar to other bacterial ABC transporters. However, unlike canonical bacterial ABC transporters, Mce1 and Mce4 appear to share a single ATPase, MceG. Previously, it was established that Mce1 and Mce4 are destabilized when key transporter subunits are rendered nonfunctional; therefore, we investigated here the role of MceG in Mce1 and Mce4 protein stability. We determined that key residues in the Walker B domain of MceG are required for the Mce1- and Mce4-mediated transport of fatty acids and cholesterol. Previously, it has been established that Mce1 and Mce4 are destabilized and/or degraded when key transporter subunits are rendered nonfunctional, thus we investigated a role for MceG in stabilizing Mce1 and Mce4. Using an unbiased quantitative proteomic approach, we demonstrate that Mce1 and Mce4 proteins are specifically degraded in mutants lacking MceG. Furthermore, bacteria expressing Walker B mutant variants of MceG failed to stabilize Mce1 and Mce4, and we show that deleting MceG impacts the fitness of Mtb in the lungs of mice. Thus, we conclude that MceG represents an enzymatic weakness that can be potentially leveraged to disable and destabilize both the Mce1 and Mce4 transporters in Mtb.

Relationships between preadmission variables and academic outcomes for postbaccalaureate students in medical school.

There is currently little guidance for medical school admissions committees regarding how to weigh postbaccalaureate program grades relative to undergraduate grades. This study was designed to address this issue. Admissions data, preclerkship course performance and United States Medical Licensing Exam (USMLE) Step 1 results were analyzed over three years for University of California, San Diego (UCSD) postbaccalaureate premedical (PBPM) students (n = 25), students who participated in other postbaccalaureate programs (n = 34), and for the remainder of the medical students who did not participate in any postbaccalaureate programs (n = 329). UCSD PBPM program alumni did not significantly differ in their cumulative academic performance on exams in preclerkship courses and USMLE Step 1 pass rates compared to the rest of the class despite their significantly lower GPA, lower Biology, Chemistry, Physics and Math (BCPM) GPA, and Medical College Admissions Test (MCAT) percentiles. For students who participated in the PBPM programs, PBPM program GPA was a significant predictor of preclerkship academic performance and USMLE Step 1 performance. When assessing academic readiness of applicants who have completed postbaccalaureate programs, admissions committees might closely consider the postbaccalaureate program GPA in addition to other academic metrices such as BCPM GPA and MCAT score.

A novel insertion mutation in atlastin 1 is associated with spastic quadriplegia, increased membrane tethering, and aberrant conformational switching.

Hereditary spastic paraplegia (HSP) comprises a heterogeneous group of neuropathies affecting upper motor neurons and causing progressive gait disorder. Mutations in the gene SPG3A/atlastin-1 (ATL1), encoding a dynamin superfamily member, which utilizes the energy from GTP hydrolysis for membrane tethering and fusion to promote the formation of a highly branched, smooth endoplasmic reticulum (ER), account for approximately 10% of all HSP cases. The continued discovery and characterization of novel disease mutations are crucial for our understanding of HSP pathogenesis and potential treatments. Here, we report a novel disease-causing, in-frame insertion in the ATL1 gene, leading to inclusion of an additional asparagine residue at position 417 (N417ins). This mutation correlates with complex, early-onset spastic quadriplegia affecting all four extremities, generalized dystonia, and a thinning of the corpus callosum. We show using limited proteolysis and FRET-based studies that this novel insertion affects a region in the protein central to intramolecular interactions and GTPase-driven conformational change, and that this insertion mutation is associated with an aberrant prehydrolysis state. While GTPase activity remains unaffected by the insertion, membrane tethering is increased, indicative of a gain-of-function disease mechanism uncommon for ATL1-associated pathologies. In conclusion, our results identify a novel insertion mutation with altered membrane tethering activity that is associated with spastic quadriplegia, potentially uncovering a broad spectrum of molecular mechanisms that may affect neuronal function.

The hypervariable region of atlastin-1 is a site for intrinsic and extrinsic regulation.

Atlastin (ATL) GTPases catalyze homotypic membrane fusion of the peripheral endoplasmic reticulum (ER). GTP-hydrolysis-driven conformational changes and membrane tethering are prerequisites for proper membrane fusion. However, the molecular basis for regulation of these processes is poorly understood. Here we establish intrinsic and extrinsic modes of ATL1 regulation that involve the N-terminal hypervariable region (HVR) of ATLs. Crystal structures of ATL1 and ATL3 exhibit the HVR as a distinct, isoform-specific structural feature. Characterizing the functional role of ATL1's HVR uncovered its positive effect on membrane tethering and on ATL1's cellular function. The HVR is post-translationally regulated through phosphorylation-dependent modification. A kinase screen identified candidates that modify the HVR site specifically, corresponding to the modifications on ATL1 detected in cells. This work reveals how the HVR contributes to efficient and potentially regulated activity of ATLs, laying the foundation for the identification of cellular effectors of ATL-mediated membrane processes.

Hyaluronic acid synthesis, degradation, and crosslinking in equine osteoarthritis: TNF-α-TSG-6-mediated HC-HA formation.

BACKGROUND: TNF-α-stimulated gene 6 (TSG-6) protein, a TNF-α-responsive hyaladherin, possesses enzymatic activity that can catalyze covalent crosslinks of the polysaccharide hyaluronic acid (HA) to another protein to form heavy chain-hyaluronic acid (HC-HA) complexes in pathological conditions such as osteoarthritis (OA). Here, we examined HA synthase and inflammatory gene expression; synovial fluid HA, TNF-α, and viscosity; and TSG-6-mediated HC-HA complex formation in an equine OA model. The objectives of this study were to (1) evaluate the TNF-α-TSG-6-HC-HA signaling pathway across multiple joint tissues, including synovial membrane, cartilage, and synovial fluid, and (2) determine the impact of OA on synovial fluid composition and biophysical properties. METHODS: HA and inflammatory cytokine concentrations (TNF-α, IL-1ß, CCL2, 3, 5, and 11) were analyzed in synovial fluid from 63 OA and 25 control joints, and HA synthase (HAS1-3), TSG-6, and hyaluronan-degrading enzyme (HYAL2, HEXA) gene expression was measured in synovial membrane and cartilage. HA molecular weight (MW) distributions were determined using agarose gel electrophoresis and solid-state nanopore measurements, and HC-HA complex formation was detected via immunoblotting and immunofluorescence. SEC-MALS was used to evaluate TSG-6-mediated HA crosslinking, and synovial fluid and HA solution viscosities were analyzed using multiple particle-tracking microrheology and microfluidic measurements, respectively. RESULTS: TNF-α concentrations were greater in OA synovial fluid, and TSG6 expression was upregulated in OA synovial membrane and cartilage. TSG-6-mediated HC-HA complex formation was greater in OA synovial fluid and tissues than controls, and HC-HA was localized to both synovial membrane and superficial zone chondrocytes in OA joints. SEC-MALS demonstrated macromolecular aggregation of low MW HA in the presence of TSG-6 and inter-α-inhibitor with concurrent increases in viscosity. CONCLUSIONS: Synovial fluid TNF-α concentrations, synovial membrane and cartilage TSG6 gene expression, and HC-HA complex formation were increased in equine OA. Despite the ability of TSG-6 to induce macromolecular aggregation of low MW HA with resultant increases in the viscosity of low MW HA solutions in vitro, HA concentration was the primary determinant of synovial fluid viscosity rather than HA MW or HC-HA crosslinking. The TNF-α-TSG-6-HC-HA pathway may represent a potential therapeutic target in OA.

Associations of Postbaccalaureate Coursework with Underrepresented Race/Ethnicity, Academic Performance, and Primary Care Training among Matriculants at Five California Medical Schools.

Studies employing data collected over 15 years ago suggested salutary effects of postbaccalaureate (PB) premedical coursework on medical school class diversity, academic performance, and primary care training. The studies may have limited current applicability given changes in medical school admissions paradigms and population demographics. Using data from interviewees at >1 of 5 California public medical schools between 2011-2013 (N=3805), we examined associations of PB premedical coursework with underrepresented race/ethnicity; academic performance (United States Medical Licensing Examination Step 1 and Step 2 scores, clerkship Honors); and primary care residency. Adjusting for age, sex, and year, PB coursework was associated with underrepresented race/ethnicity, but not after further adjustment for self-designated disadvantage (SDA). PB coursework was not associated with academic performance or primary care residency. Holistic consideration of SDA and UIM status in admissions coupled with robust matriculant support may merit exploration as an alternative to PB coursework for increasing medical school diversity.

Nucleotide-Dependent Dimerization and Conformational Switching of Atlastin.

A common feature of dynamin-related proteins (DRPs) is their use of guanosine triphosphate (GTP) to control protein dynamics. In the case of the endoplasmic- reticulum- (ER)-resident membrane protein atlastin (ATL), GTP binding and hydrolysis result in membrane fusion of ER tubules and the generation of a branched ER network. In this chapter, we describe two independent methods for dissecting the mechanism underlying nucleotide-dependent quaternary structure and conformational changes of ATL, focusing on size-exclusion chromatography coupled with multi-angle light scattering (SEC-MALS) and Förster resonance energy transfer (FRET), respectively. The high temporal resolution of the FRET-based assays enables the ordering of the molecular events identified in structural and equilibrium-based SEC-MALS studies. In combination, these complementary methods report on the oligomeric states of a system at equilibrium and timing of key steps along the enzyme's catalytic cycle. These methods are broadly applicable to proteins that undergo ligand-induced dimerization and/or conformational changes.

The Relationships among Self-Designated Disadvantage, Socioeconomic Disadvantage, and Academic Performance in Medical School: A Multi-Institutional Study.

As medical schools seek to address the growing disparity between the socioeconomic makeup of their students and the general population, it is important to understand the academic trajectory of disadvantaged students. We used a locally-developed multicomponent socioeconomic disadvantage (SED) measure and the self-designated disadvantaged (SDA) question ["yes" (+) or "no" (-)] from the American Medical College Application Service application to examine academic performance of students from three disadvantaged categories (high SED/SDA+, high SED/SDA-, and low SED/SDA+); with low SED/SDA-as the reference group across five California schools. Compared with reference, the DA+ subgroups scored lower on USMLE Step 1 and Step 2 Clinical Knowledge examinations and received fewer clerkship Honors. After adjustment for academic metrics and sociodemographic variables, high SED subgroups performed similarly to reference, but performance gaps for low SED/SDA+ students persisted. Medical schools must better understand the institutional and other drivers of academic success in disadvantaged students.

Dean's Perspective on Academic Communities at UC San Diego, School of Medicine.

INTRODUCTION AND BACKGROUND: In 2010, the UC San Diego School of Medicine launched a new curriculum, the integrated scientific curriculum. As part of this curricular redesign, the school instituted academic communities. This perspective article outlines our experience with the first 8 years of these academic communities. SINGLE-INSTITUTION EXPERIENCE: We initiated academic communities with the hope that this structure would cultivate enhanced student-student and student-faculty engagement, improve faculty-student mentoring, and create additional service-learning and student leadership opportunities. The communities would also provide an environment for small group learning throughout the 4-year curriculum. After 8 years of experience, a comparison of student survey data pre- and post establishment of academic communities demonstrated enhanced connectedness between students and faculty and higher scores for faculty mentoring and for career planning. Our own lived experience with the communities revealed several unanticipated outcomes. The community directors became a source of support and advice for one another. Some faculty and administrators whose previous roles were affected by start of the academic communities needed to adjust expectations. CONCLUSIONS: The establishment of academic communities was associated with improvement in student-faculty engagement, student assessment of faculty mentoring, and career planning.

Do Admissions Multiple Mini-Interview and Traditional Interview Scores Predict Subsequent Academic Performance? A Study of Five California Medical Schools.

PURPOSE: To compare the predictive validities of medical school admissions multiple mini-interviews (MMIs) and traditional interviews (TIs). METHOD: This longitudinal observational study of 2011-2013 matriculants to five California public medical schools examined the associations of MMI scores (two schools) and TI scores (three schools) with subsequent academic performance. Regression models adjusted for sociodemographics and undergraduate academic metrics examined associations of standardized mean MMI and TI scores with United States Medical Licensing Examination Step 1 and Step 2 Clinical Knowledge (CK) scores and, for required clerkships, with mean National Board of Medical Examiners Clinical Science subject (shelf) exam score and number of honors grades. RESULTS: Of the 1,460 medical students, 746 (51.1%) interviewed at more than one study school; 579 (39.7%) completed at least one MMI and at least one TI. Neither interview type was associated with Step 1 scores. Higher MMI scores were associated with more clerkship honors grades (adjusted incidence rate ratio [AIRR] 1.28 more [95% CI 1.18, 1.39; P < .01] per SD increase) and higher shelf exam and Step 2 CK scores (adjusted mean 0.73 points higher [95% CI 0.28, 1.18; P < .01] and 1.25 points higher [95% CI 0.09, 2.41; P = .035], respectively, per SD increase). Higher TI scores were associated only with more honors grades (AIRR 1.11 more [95% CI 1.01, 1.20; P = .03] per SD increase). CONCLUSIONS: MMI scores were more strongly associated with subsequent academic performance measures than were TI scores.

Do Multiple Mini-Interview and Traditional Interview Scores Differ in Their Associations With Acceptance Offers Within and Across Five California Medical Schools?

PURPOSE: In single-school studies, multiple mini-interview (MMI) and traditional interview (TI) scores are associated with acceptance offers. Unexamined is whether scores at one school are associated with acceptance at other schools; such analyses would mitigate single-school design biases and better estimate how well interviews capture desired applicant attributes. Using data from the 5 California Longitudinal Evaluation of Admissions Practices (CA-LEAP) medical schools, the authors examined associations of MMI and TI scores with acceptance offers within and across schools. METHOD: The analyses included applicants who interviewed at ≥1 CA-LEAP school during the 2011-2013 admissions cycles. Three CA-LEAP schools employed TIs and 2 employed MMIs. Interview scores were standardized (z scores: mean = 0, SD = 1), and associations with acceptance offers were examined within and across schools in analyses stratified by school, adjusting for applicant sociodemographics, academic metrics, year, and total number of interviews. RESULTS: Of 4,993 applicants interviewed, 428 (8.6%) interviewed at both MMI schools, 681 (13.6%) at ≥2 TI schools, and 1,327 (26.6%) at ≥1 MMI and ≥1 TI school. For each school, acceptance was associated with interview score at that school and also with interview scores at the other 4 schools. Cross-school associations of MMI versus TI scores with acceptance did not differ statistically. CONCLUSIONS: Interview score at a given school was associated with acceptance at the other 4 schools, with no significant differences in associations for MMIs versus TIs. The findings suggest both MMIs and TIs captured attributes valued by admissions teams across CA-LEAP schools.

An N-Terminal Retention Module Anchors the Giant Adhesin LapA of Pseudomonas fluorescens at the Cell Surface: a Novel Subfamily of Type I Secretion Systems.

LapA of Pseudomonas fluorescens Pf0-1 belongs to a diverse family of cell surface-associated bacterial adhesins that are secreted via the type I secretion system (T1SS). We previously reported that the periplasmic protease LapG cleaves the N terminus of LapA at a canonical dialanine motif to release the adhesin from the cell surface under conditions unfavorable to biofilm formation, thus decreasing biofilm formation. Here, we characterize LapA as the first type I secreted substrate that does not follow the "one-step" rule of T1SS. Rather, a novel N-terminal element, called the retention module (RM), localizes LapA at the cell surface as a secretion intermediate. Our genetic, biochemical, and molecular modeling analyses support a model wherein LapA is tethered to the cell surface through its T1SS outer membrane TolC-like pore, LapE, until LapG cleaves LapA in the periplasm. We further demonstrate that this unusual retention strategy is likely conserved among LapA-like proteins, and it reveals a new subclass of T1SS ABC transporters involved in transporting this group of surface-associated LapA-like adhesins. These studies demonstrate a novel cell surface retention strategy used throughout the Proteobacteria and highlight a previously unappreciated flexibility of function for T1SS.IMPORTANCE Bacteria have evolved multiple secretion strategies to interact with their environment. For many bacteria, the secretion of cell surface-associated adhesins is key for initiating contact with a preferred substratum to facilitate biofilm formation. Our work demonstrates that P. fluorescens uses a previously unrecognized secretion strategy to retain the giant adhesin LapA at its cell surface. Further, we identify likely LapA-like adhesins in various pathogenic and commensal proteobacteria and provide phylogenetic evidence that these adhesins are secreted by a new subclass of T1SS ABC transporters.

A summer prematriculation program to help students succeed in medical school.

Medical schools with a diverse student body face the challenge of ensuring that all students succeed academically. Many medical schools have implemented prematriculation programs to prepare students from diverse backgrounds; however, evidence on their impact is largely lacking. In this study, we analyzed participants' demographics as well as the impact of the prematriculation program on Year 1 performance. Predictive validity of the program was assessed and compared to other traditional predictors, including grade point average (GPA) and Medical College Admission Test (MCAT) scores and subscores. Linear mixed effect models determined the impact of the prematriculation program, and linear regression analysis assessed the predictive value of the overall score in the prematriculation program and other traditional predictors. Demographics of students participating in the prematriculation program from 2013 to 2015 (n = 75) revealed a significantly higher prevalence of academically disadvantaged students including older students, students with lower GPA and MCAT scores and students of racial and ethnic populations that are underrepresented in medicine, compared to non-participants (n = 293). Participants performed significantly better in Year 1 courses that were covered in the prematriculation program compared to courses that were not covered. The overall performance in the prematriculation program correlated significantly with Year 1 performance and was found to be a strong predictor for Year 1 performance. This study suggests that a prematriculation program can help students to succeed in the first year of medical school. The results have implications for medical schools seeking to implement or evaluate the effectiveness of their prematriculation program.

Medical School Applicant Characteristics Associated With Performance in Multiple Mini-Interviews Versus Traditional Interviews: A Multi-Institutional Study.

PURPOSE: To examine applicant characteristics associated with multiple mini-interview (MMI) or traditional interview (TI) performance at five California medical schools. METHOD: Of the five California Longitudinal Evaluation of Admission Practices consortium schools, three used TIs and two used MMIs. Schools provided retrospective data on 2011-2013 admissions cycle interviewees: age, gender, race/ethnicity (underrepresented in medicine [UIM] or not), disadvantaged (DA) status, undergraduate GPA, Medical College Admission Test (MCAT) score, and interview score (standardized as z score; mean = 0; SD = 1). Adjusted linear regression analyses, stratified by interview type, examined associations with interview performance. RESULTS: The 4,993 applicants who completed 7,516 interviews included 931 (18.6%) UIM and 962 (19.3%) DA individuals; 3,226 (64.6%) had only 1 interview. Mean age was 24.4 (SD = 2.7); mean GPA and MCAT score were 3.72 (SD = 0.22) and 33.6 (SD = 3.7), respectively. Older age, female gender, and number of prior interviews were associated with better performance on both MMIs and TIs. Higher GPA was associated with lower MMI scores (z score, per unit GPA = -0.26; 95% CI = -0.45, -0.06) but unrelated to TI scores. DA applicants had higher TI scores (z score = 0.17; 95% CI = 0.07, 0.28) but lower MMI scores (z score = -0.18; 95% CI = -0.28, -0.08) than non-DA applicants. Neither UIM status nor MCAT score was associated with interview performance. CONCLUSIONS: These findings have potentially important workforce implications, particularly regarding MMI performance of DA applicants, and illustrate the need for other multi-institutional studies.

Reliability of Multiple Mini-Interviews and traditional interviews within and between institutions: a study of five California medical schools.

BACKGROUND: Many medical schools use admissions Multiple Mini-Interviews (MMIs) rather than traditional interviews (TIs), partly because MMIs are thought to be more reliable. Yet prior studies examined single-school samples of candidates completing either an MMI or TI (not both). Using data from five California public medical schools, the authors examined the within- and between-school reliabilities of TIs and MMIs. METHODS: The analyses included applicants interviewing at ≥1 of the five schools during 2011-2013. Three schools employed TIs (TI1, TI2, TI3) and two employed MMIs (MMI1, MMI2). Mixed linear models accounting for nesting of observations within applicants examined standardized TI and MMI scores (mean = 0, SD = 1), adjusting for applicant socio-demographics, academic metrics, year, number of interviews, and interview date. RESULTS: A total of 4993 individuals (completing 7516 interviews [TI = 4137, MMI = 3379]) interviewed at ≥1 school; 428 (14.5%) interviewed at both MMI schools and 687 (20.2%) at more than one TI school. Within schools, inter-interviewer consistency was generally qualitatively lower for TI1, TI2, and TI3 (Pearson's r 0.07, 0.13, and 0.29, and Cronbach's α, 0.40, 0.44, and 0.61, respectively) than for MMI1 and MMI 2 (Cronbach's α 0.68 and 0.60, respectively). Between schools, the adjusted intraclass correlation coefficient was 0.27 (95% CI 0.20-0.35) for TIs and 0.47 (95% CI 0.41-0.54) for MMIs. CONCLUSIONS: Within and between-school reliability was qualitatively higher for MMIs than for TIs. Nonetheless, TI reliabilities were higher than anticipated from prior literature, suggesting TIs may not need to be abandoned on reliability grounds if other factors favor their use.

Timing and Reset Mechanism of GTP Hydrolysis-Driven Conformational Changes of Atlastin.

The endoplasmic reticulum (ER) forms a branched, dynamic membrane tubule network that is vital for cellular function. Branching arises from membrane fusion facilitated by the GTPase atlastin (ATL). Many metazoan genomes encode for three ATL isoforms that appear to fulfill partially redundant function despite differences in their intrinsic GTPase activity and localization within the ER; however, the underlying mechanistic differences between the isoforms are poorly understood. Here, we identify discrete temporal steps in the catalytic cycle for the two most dissimilar isoforms, ATL1 and ATL3, revealing an overall conserved progression of molecular events from nucleotide binding and hydrolysis to ATL dimerization and phosphate release. A crystal structure of ATL3 suggests a mechanism for the displacement of the catalytic Mg2+ ion following guanosine triphosphate (GTP) hydrolysis. Together, the data extend the mechanistic framework for how GTP hydrolysis drives conformational changes in ATL and how the cycle is reset for subsequent rounds of catalysis.

Effect of a Dedicated Pharmacy Student Summer Research Program on Publication Rate.

Objectives. This study investigated the impact of an optional 12-week summer research program on the publication outcomes and satisfaction with the required research projects of doctor of pharmacy (PharmD) students at the Skaggs School of Pharmacy and Pharmaceutical Sciences (SSPPS) at the University of California San Diego. Methods. PubMed and Google searches provided student publications, and satisfaction surveys submitted by students provided their perceptions of the research project value. Results. Of the studied cohort, the 130 students who fulfilled the requirement through the optional summer research program provided 61 full-text manuscripts and 113 abstracts. The 305 students who chose the standard pathway provided 35 full-text manuscripts and 34 abstracts. Students in both pathways agreed or strongly agreed that the research project was a valuable experience. Conclusions. The 12-week intensive summer research program improved the publication rate of pharmacy students and provided a high overall satisfaction with this independent learning experience.

Small group activities within academic communities improve the connectedness of students and faculty.

BACKGROUND: The University of California, San Diego, School of Medicine implemented a curriculum change that included reduction of lectures, incorporation of problem-based learning and other small group activities. Six academic communities were introduced for teaching longitudinal curricular content and organizing extracurricular activities. METHODS: Surveys were collected from 904 first- and second-year medical students over 6 years. Student satisfaction data with their sense of connectedness and community support were collected before and after the implementation of the new curriculum. In a follow-up survey, medical students rated factors that contributed to their sense of connectedness with faculty and students (n = 134). RESULTS: Students' perception of connectedness to faculty significantly increased following implementation of a curriculum change that included academic communities. Students ranked small group clinical skills activities within academic communities significantly higher than other activities concerning their sense of connectedness with faculty. Students' perception of connectedness among each other was high at baseline and did not significantly change. Small group activities scored higher than extracurricular activities regarding students' connectedness among themselves. CONCLUSIONS: The implementation of a new curriculum with more small group educational activities including academic communities enhanced connectedness between students and faculty and resulted in an increased sense of community.

Are self-identified "disadvantaged" students less likely to enter surgical residencies? A single-institution study.

BACKGROUND: Given more emphasis on training primary care physicians for underserved areas, we hypothesized that students self-identifying as "disadvantaged" would be less likely to pursue surgical training. METHODS: We retrospectively reviewed medical school data on students graduating 2005-2014. Students were stratified into "disadvantaged" and "nondisadvantaged". Data were recorded on age, grade point average, Medical College Admission Test (MCAT), gender, surgery grade, United States Medical Licensing Examination step 1 score, and residency match into a surgical field. A comparison of the proportion of students matching into a surgical field was assessed with chi-square test. Multivariate logistic regression was performed to assess the factors that predict the choice of general surgery versus another surgical field. RESULTS: Of the 1140 students who graduated during the study period, 219 (19.2%) students self-identified as "disadvantaged". Of all students, 158 (13.9%) chose a surgical field. The disadvantaged group was older at entry and had lower grade point average and total MCAT scores. Twenty-seven (12.3%) disadvantaged students chose a surgical residency versus 130 (14.1%) nondisadvantaged students (P = 0.56). On multivariate logistic regression, female gender (odds ratio [OR] = 3.9; 95% confidence interval = [1.9-8.3], P < 0.01), disadvantaged status (OR = 2.8 [1.1-7.1], P = 0.03), and United States Medical Licensing Examination step 1 score ≥ 227 (OR = 0.43 [0.21-0.88], P = 0.02) were significantly associated with matching into general surgery versus another surgical specialty. DISCUSSION: Although the disadvantaged cohort was older and had lower undergraduate GPAs and MCAT scores, the proportion of disadvantaged students matching into a surgical residency was not statistically different. To address the future shortage of general surgeons in underserved areas, increasing enrollment of "disadvantaged" students may alleviate the "surgical desert".
