Looks at case studies of four innovative clinical programs to determine key factors influencing the diffusion and adoption of innovations in health care

A Conceptual Model for Navigating a Career Path in Medical School Leadership

There is a paucity of literature providing guidance to physicians hoping to attain a position as a medical school dean. Realizing this gap, the Society for Academic Emergency Medicine (SAEM) Faculty Development Committee organized an educational session focused on offering faculty guidance for obtaining a position in medical school leadership. The session involved panelists who are nationally known leaders in medical school administration and was successfully presented at the SAEM 2018 annual meeting in Indianapolis, Indiana. Knowledge and perspective gained both during this session and through literature review was analyzed using a conceptual thinking skills framework. This process offered insights that promoted the development of a conceptual model informed by current evidence and expert insight and rooted in educational, economic, and cognitive theory. This model provides a step‐by‐step guide detailing a process that physicians can use to create a plan for professional development that is informed, thoughtful, and individualized to their own needs to optimize their future chances of advancing to a career in medical school leadership.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146843/1/aet210212.pd

Dental-related Emergency Department Visits and Community Dental Care Resources for Emergency Room Patients

BACKGROUND: The number and cost of dental-related visits to Emergency Departments (ED) is a significant issue nationwide. A better understanding of the treatment provided to ED patients presenting with dental complaints and community dental resources is needed. METHODS: A three-tiered approach included: 1) a 12-month retrospective chart review for dental-related ICD-9 visit codes at an urban academic ED in Kansas City; 2) surveys of 30 providers at the same ED regarding the dental patient process and treatment; and 3) telephone surveys of 16 Kansas City area safety net clinics regarding service access. RESULTS: Out of 49,276 ED visits, 676 were related to dental conditions (70 were repeat dental ED visits). Most patients were female (54%), white (45%), age 20-39 (65%), and self-pay (56%). The most prevalent codes utilized were dental disorder not otherwise specified (NOS; 57%), periapical abscess (22%), and dental caries NOS (15%). Nearly all providers (97%) felt comfortable seeing patients with dental complaints. Chart review indicated that patients received a dental screen/exam during 80% of the encounters, with medication provided to 90% of the patients. Over two-thirds of the providers (N = 23/30) regularly prescribed antibiotics and pain medications for their ED dental patients. ED providers performed dental procedures in 63% of the patient cases. The most common procedures included dental blocks (N = 16 providers) and incision and drainage (N = 4 providers). Only two of the 16 safety net clinics provided comprehensive dental care, almost all (94%) clinics required patients to call to schedule an appointment, and there was a two to six month waiting period for 31% of the clinics. CONCLUSION: The limited scope of dental treatment in the ED, coupled with poor availability of safety-net dental resources, may result in dental exacerbations and suboptimal patient clinical outcomes. The enhancement of safety-net dental service accessibility is crucial to reducing dental ED visits and improving dental health, particularly among low-income, self-pay populations

Integrated TiO2 resonators for visible photonics

We demonstrate waveguide-coupled titanium dioxide (TiO2) racetrack resonators with loaded quality factors of 2x10^4 for the visible wavelengths. The structures were fabricated in sputtered TiO2 thin films on oxidized silicon substrates using standard top-down nanofabrication techniques, and passively probed in transmission measurements using a tunable red laser. Devices based on this material could serve as integrated optical elements as well as passive platforms for coupling to visible quantum emitters.Comment: 4 pages, 3 figure

The Very Young Type Ia Supernova 2012cg: Discovery and Early-Time Follow-Up Observations

On 2012 May 17.2 UT, only 1.5 +/- 0.2 d after explosion, we discovered SN 2012cg, a Type Ia supernova (SN Ia) in NGC 4424 (d ~ 15 Mpc). As a result of the newly modified strategy employed by the Lick Observatory SN Search, a sequence of filtered images was obtained starting 161 s after discovery. Utilizing recent models describing the interaction of SN ejecta with a companion star, we rule out a ~1 M_Sun companion for half of all viewing angles and a red-giant companion for nearly all orientations. SN 2012cg reached a B-band maximum of 12.09 +/- 0.02 mag on 2012 June 2.0 and took ~17.3 d from explosion to reach this, typical for SNe Ia. Our pre-maximum brightness photometry shows a narrower-than-average B-band light curve for SN 2012cg, though slightly overluminous at maximum brightness and with normal color evolution (including some of the earliest SN Ia filtered photometry ever obtained). Spectral fits to SN 2012cg reveal ions typically found in SNe Ia at early times, with expansion velocities >14,000 km/s at 2.5 d past explosion. Absorption from C II is detected early, as well as high-velocity components of both Si II 6355 Ang. and Ca II. Our last spectrum (13.5 d past explosion) resembles that of the somewhat peculiar SN Ia 1999aa. This suggests that SN 2012cg will have a slower-than-average declining light curve, which may be surprising given the faster-than-average rising light curve.Comment: re-submitted to ApJL, 4 figures, 1 tabl

Assessing the impact of sample size and geology on earthen embankment design and construction

This technical paper investigates the influence of sample size and geologic characteristics on the geotechnical design of levee embankments. Sample quality plays a vital role in quantifying engineering properties for levee embankment projects, and numerous studies have highlighted the impact of sample disturbance on such engineering properties. Despite this evidence, conventional tube and piston samplers of different diameters continue to be widely used, potentially leading to underestimation of shear strength. The paper focuses on comparing 7.6 cm and 12.7 cm diameter undisturbed Shelby tube samples and CPT data collected from three levee sites in the Greater New Orleans Area, Louisiana, USA, which encompass diverse geologic histories. The study aims to assess the effect of industry used samples size and geology on levee construction costs. The findings provide valuable insights into optimizing sample collection methods and improving geotechnical design for earthen embankments

The Lick AGN Monitoring Project 2011: Dynamical Modeling of the Broad Line Region in Mrk 50

We present dynamical modeling of the broad line region (BLR) in the Seyfert 1 galaxy Mrk 50 using reverberation mapping data taken as part of the Lick AGN Monitoring Project (LAMP) 2011. We model the reverberation mapping data directly, constraining the geometry and kinematics of the BLR, as well as deriving a black hole mass estimate that does not depend on a normalizing factor or virial coefficient. We find that the geometry of the BLR in Mrk 50 is a nearly face-on thick disk, with a mean radius of 9.6(+1.2,-0.9) light days, a width of the BLR of 6.9(+1.2,-1.1) light days, and a disk opening angle of 25\pm10 degrees above the plane. We also constrain the inclination angle to be 9(+7,-5) degrees, close to face-on. Finally, the black hole mass of Mrk 50 is inferred to be log10(M(BH)/Msun) = 7.57(+0.44,-0.27). By comparison to the virial black hole mass estimate from traditional reverberation mapping analysis, we find the normalizing constant (virial coefficient) to be log10(f) = 0.78(+0.44,-0.27), consistent with the commonly adopted mean value of 0.74 based on aligning the M(BH)-{\sigma}* relation for AGN and quiescent galaxies. While our dynamical model includes the possibility of a net inflow or outflow in the BLR, we cannot distinguish between these two scenarios.Comment: Accepted for publication in ApJ. 8 pages, 6 figure
