Rural Medical Student Opinions About Rural Practice: Does Choice of College Make a Difference?

Purpose While many programs assume medical students who attended rural colleges are more likely to practice in smaller towns later, there are few studies to support this assumption. This study examines aspects of medical students’ opinions about rural living and rural practice based on where they attended college. Method Students with rural upbringing were identified and administered a previously published rural health opinion survey. The opinion survey was administered across three academic years, from 2015 to 2017, and included a total of three scales and nine subscales for analysis. Factor analysis was used to identify the nine subscales. Results Respondents who attended small town colleges tended to have much stronger opinions about the positive aspects of small town living. Small town college attendees also had stronger positive opinions regarding rural practice than their larger college counterparts. Discussion These preliminary data indicate considering a medical school applicants’ choice of college may provide insight into their opinions about future rural practice. Additional research is needed to collect a larger dataset to examine the association of college choice with opinions about rural practice

Do medical residents with rural upbringing show less decline in empathy during training? A report from a rural family medicine residency

Abstract Purpose Our focus in this study was to determine if demographic variables, including specifically rural upbringing, showed any association with a measure of empathy among family medicine residents at a rural site. Methods We surveyed 40 residents annually using the Jefferson Scale of Empathy (JSE) from 2016 to 2020 and compared scores between residents with rural vs urban hometowns. The response rate was 98/99 (99%) of completed survey opportunities. Findings There was no significant difference in JSE scores of rural vs urban residents at baseline, and both groups showed a decline after the PG-1 year. However, the rural-raised residents showed a significantly different rebound after the PG-2 and PG-3 year, with the urban-raised residents actually showing a slight continuing decline (p=.023 and p=.033). Conclusion These preliminary findings among family medicine residents at a rural site suggest that rural background residents might regain empathy better than urban background residents during the course of their training. Further study should validate our findings and address possible explanations, including the importance of cultural concordance with the patient population served. This and other hypotheses will be explored in further studies with focus groups and other contemporaneous measures

Assessing Medical Students’, Residents’, and the Public's Perceptions of the Uses of Personal Digital Assistants

Although medical schools are encouraging the use of personal digital assistants (PDAs), there have been few investigations of attitudes toward their use by students or residents and only one investigation of the public's attitude toward their use by physicians. In 2006, the University of Louisville School of Medicine surveyed 121 third- and fourth-year medical students, 53 residents, and 51 members of the non-medical public about their attitudes toward PDAs. Students were using either the Palm i705 or the Dell Axim X50v; residents were using devices they selected themselves (referred to in the study generically as PDAs). Three survey instruments were designed to investigate attitudes of (a) third- and fourth-year medical students on clinical rotations, (b) Internal Medicine and Pediatrics residents, and (c) volunteer members of the public found in the waiting rooms of three university practice clinics. Both residents and medical students found their devices useful, with more residents (46.8%) than students (16.2%) (p < 0.001) rating PDAs “very useful.” While students and residents generally agreed that PDAs improved the quality of their learning, residents’ responses were significantly higher (p < 0.05) than students’. Residents also responded more positively than students that PDAs made them more effective as clinicians. Although members of the public were generally supportive of PDA use, they appeared to have some misconceptions about how and why physicians were using them. The next phase of research will be to refine the research questions and survey instruments in collaboration with another medical school

Changes In Rural Affinity Among Rural Medical Students As They Experience Education In An Urban Setting

Abstract Introduction The maldistribution of physicians in the United States has led to a shortage of healthcare providers in rural areas and rural patients being underserved. A physician’s connections to rural settings, including upbringing and medical training, often influence the decision to practice in rural areas. This study examines opinions from medical students who participated in a regional rural campus track, which includes summer immersion programs, rural-focused sessions, and clinical rotations. The authors hypothesized that Rural Track students experience urban disruption, and their opinions about rural living and practice would become increasingly less positive over time while students lived at the urban campus for preclinical coursework. Materials and Methods The Rural Health Opinion Survey (RHOS), a previously published measure of opinions concerning living and practicing in rural areas, was administered to students at one public medical school located in Louisville, Kentucky. Factor analysis was performed on each of the three sections of the survey (items related to rural living, patients in rural areas, and physicians in rural areas), and composite subscale scores were calculated for each student. The first phase of this large longitudinal study reported here uses t-tests to compare pre- and post-test scores for 36 students in the Rural Track program. Scores of M1/M2 students who were based at the urban campus were also compared to M3/M4 students who had returned to the rural campus. Results Ninety-two percent (36/39) of Rural Track students completed both pre- and post-surveys, and of these respondents, 89% percent (32/36) grew up in a hometown with fewer than 30,000 people. Overall scores were not significantly different between Rural Track M1/M2 in the urban setting and the Rural Track M3/M4 students based at the rural campus. M3/M4 students showed a differential positive opinion over time of rural comfortable living that approached significance and agreed less that the rural physician workload is heavier. M1/M2 students expressed more positive opinions over time about availability of quality service. Both groups showed strong agreement over time that rural patients are more motivated. Discussion Our hypothesis that Rural Track students on the urban campus would show increasingly less positive opinions about rural health and practice was not supported. Students may not have experienced urban disruption because of the Rural Track curriculum elements, and/or time in the urban environment may have reinforced rural affinity by providing new perspective on the positive aspects of rural settings. Further research and efforts are necessary to identify critical points of reconnection for medical students and to support rural affinity within medical school curriculum. Upcoming research efforts will address the overall hypothesis that Rural Track students’ continued connection to rural settings generates more positive opinions about rural living and practice as compared to opinions from students with rural backgrounds who spend all four years of medical school in the urban setting

Medical student interest in academic medical careers: a multi-institutional study

Little is known about how medical students view academic medicine. This multi-institutional study explored student perceptions of this career path. During 2009–2010, third- and fourth-year students at three United States medical schools completed a 30-item online survey. In total, 239 students completed the questionnaire (37 % response rate). Significant predictors of students’ desires for academic medical careers included interest in teaching (γ = 0.74), research (γ = 0.53), interprofessional practice (γ = 0.34), administration (γ = 0.27), and community service opportunities (γ = 0.16). A positive correlation existed between accumulated debt and interest in academic medicine (γ = 0.20). Student descriptions of the least and most appealing aspects of academic medicine were classified into five categories: professional, research, personal, teaching and mentoring, and patients/patient care. Students are more likely to be interested in a career in academic medicine if they have participated in research or were influenced by a mentor. Factors that may also influence a medical student’s decision to pursue a career in academic medicine include age and debt accumulated prior to medical school. Professional aspects of academic medicine (cutting edge environment, resources) and the opportunity to teach were the most appealing aspects

Hard x-ray characterization of a HEFT single-reflection prototype

We have measured the hard X-ray reflectivity and imaging performance from depth graded W/Si multilayer coated mirror segments mounted in a single reflection cylindrical prototype for the hard X-ray telescopes to be flown on the High Energy Focusing Telescope (HEFT) balloon mission. Data have been obtained in the energy range from 18 - 170 keV at the European Synchrotron Radiation Facility and at the Danish Space Research Institute at 8 keV. The modeling of the reflectivity data demonstrate that the multilayer structure can be well described by the intended power law distribution of the bilayer thicknesses optimized for the telescope performance and we find that all the data is consistent with an interfacial width of 4.5 Å. We have also demonstrated that the required 5% uniformity of the coatings is obtained over the mirror surface and we have shown that it is feasible to use similar W/Si coatings for much higher energies than the nominal energy range of HEFT leading the way for designing Gamma-ray telescopes for future astronomical applications. Finally we have demonstrate 35 arcsecond Half Power Diameter imaging performance of the one bounce prototype throughout the energy range of the HEFT telescopes

Quantitative mapping of collagen fiber orientation in non-glaucoma and glaucoma posterior human scleras

Purpose. The posterior sclera has a major biomechanical influence on the optic nerve head, and may therefore be important in glaucoma. Scleral material properties are influenced significantly by collagen fiber architecture. Here we quantitatively map fiber orientation in non-glaucoma and glaucoma posterior human sclerae. Methods. Wide-angle x-ray scattering quantified fiber orientation at 0.5-mm intervals across seven non-glaucoma post-mortem human sclerae, and five sclerae with glaucoma history and confirmed axon loss. Multiphoton microscopy provided semiquantitative depth-profiling in the peripapillary sclera. Results. Midposterior fiber orientation was either uniaxial (one preferred direction) or biaxial (two directions). The peripapillary sclera was characterized by a ring of fibers located mainly in the mid-/outer stromal depth and encompassing ∼50% of the total tissue thickness. Fiber anisotropy was 37% higher in the peripapillary sclera compared with midposterior, varied up to 4-fold with position around the scleral canal, and was consistently lowest in the superior-nasal quadrant. Mean fiber anisotropy was significantly lower in the superior-temporal (P < 0.01) and inferior-nasal (P < 0.05) peripapillary scleral quadrants in glaucoma compared with non-glaucoma eyes. Conclusions. The collagen fiber architecture of the posterior human sclera is highly anisotropic and inhomogeneous. Regional differences in peripapillary fiber anisotropy between non-glaucoma and glaucoma eyes may represent adaptive changes in response to elevated IOP and/or glaucoma, or baseline structural properties that associate with predisposition to glaucomatous axon damage. Quantitative fiber orientation data will benefit numerical eye models aimed at predicting the sclera's influence on nerve head biomechanics, and thereby its possible role in glaucoma

Melting and differentiation of early-formed asteroids: The perspective from high precision oxygen isotope studies

A number of distinct methodologies are available for determining the oxygen isotope composition of minerals and rocks, these include laser-assisted fluorination, secondary ion mass spectrometry (SIMS)and UV laser ablation. In this review we focus on laser-assisted fluorination, which currently achieves the highest levels of precision available for oxygen isotope analysis. In particular, we examine how results using this method have furthered our understanding of early-formed differentiated meteorites. Due to its rapid reaction times and low blank levels, laser-assisted fluorination has now largely superseded the conventional externally-heated Ni “bomb” technique for bulk analysis. Unlike UV laser ablation and SIMS analysis, laser-assisted fluorination is not capable of focused spot analysis. While laser fluorination is now a mature technology, further analytical improvements are possible via refinements to the construction of sample chambers, clean-up lines and the use of ultra-high resolution mass spectrometers. High-precision oxygen isotope analysis has proved to be a particularly powerful technique for investigating the formation and evolution of early-formed differentiated asteroids and has provided unique insights into the interrelationships between various groups of achondrites. A clear example of this is seenin samples that lie close to the terrestrial fractionation line (TFL). Based on the data from conventional oxygen isotope analysis, it was suggested that the main-group pallasites, the howardite eucrite diogenite suite (HEDs) and mesosiderites could all be derived from a single common parent body. However,high precision analysis demonstrates that main-group pallasites have a Δ17O composition that is fully resolvable from that of the HEDs and mesosiderites, indicating the involvement of at least two parent bodies. The range of Δ17O values exhibited by an achondrite group provides a useful means of assessing the extent to which their parent body underwent melting and isotopic homogenization. Oxygen isotope analysis can also highlight relationships between ungrouped achondrites and the more well-populated groups. A clear example of this is the proposed link between the evolved GRA 06128/9 meteorites and the brachinites. The evidence from oxygen isotopes, in conjunction with that from other techniques, indicates that we have samples from approximately 110 asteroidal parent bodies (∼60 irons, ∼35 achondrites and stony-iron, and ∼15 chondrites) in our global meteorite collection. However, compared to the likely size of the original protoplanetary asteroid population, this is an extremely low value. In addition, almost all of the differentiated samples (achondrites, stony-iron and irons) are derived from parent bodies that were highly disrupted early in their evolution. High-precision oxygen isotope analysis of achondrites provides some important insights into the origin of mass-independent variation in the early Solar System. In particular, the evidence from various primitive achondrite groups indicates that both the slope 1 (Y&R) and CCAM lines are of primordial significance. Δ17O differences between water ice and silicate-rich solids were probably the initial source of the slope 1 anomaly. These phases most likely acquired their isotopic composition as a result of UV photo-dissociation of CO that took place either in the early solar nebula or precursor giant molecular cloud. Such small-scale isotopic heterogeneities were propagated into larger-sized bodies, such as asteroids and planets, as a result of early Solar System processes, including dehydration, aqueous alteration,melting and collisional interactions
