Delivering the AAMC “Teaching for Quality” Program through a Community-Based GME Collaborative: Lessons Learned to Date
Authors: Church Brandy , Corser William , Rohrer Jonathan , Hortos Kari , Harrison Angela 
Published: February 2021

CONTEXT To address scholarly activity (SA) accreditation standards, the Michigan State University’s College of Osteopathic Medicine Statewide Campus System has offered the Association of American Medical Colleges’ (AAMC) Teaching for Quality Program for two cohorts of community-based faculty. The purpose of this paper was to describe the design and delivery of the customized program, the authors’ initial lessons learned, and their plans for further evaluation and dissemination. METHODS The authors customized the program to overcome the barriers typically faced by community-based program faculty learners through a graduate medical education (GME) consortium model. This was the first time this program was delivered in this manner RESULTS The authors’ initial cohort of 19 learners successfully developed 15 projects, with two pairs of learners collaborating on projects. The second cohort of 15 learners developed 11 projects, with one pair of learners collaborating. The authors present a series of principles for community-based GME leaders striving to develop SA projects in their respective GME environments. CONCLUSIONS The “consortium advantage” derived from entities such as the SCS may prove integral to efficiently coordinating SA project resources and knowledge across diverse GME systems.
An Atypical Case of Transverse Diverticulitis and the Changing Management of Diverticular Disease
Authors: Ostosh Andrew C. , Saleh Adeeb , Boehm Kevin M. 
Published: February 2021

Diverticulitis is an inflammation of an out pouching of the lower gastrointestinal tract, particularly in the large intestine. Although the condition is taught to medical students as typically occurring in the left lower quadrant of the abdomen, right-sided and transverse forms diverticulitis can occur. Uncomplicated, e.g., non-perforated, diverticulitis is usually treated with antibiotics. Complicated, e.g. perforated, is usually treated with surgery. The purpose of this case report is to present an atypical case of perforated diverticulitis and review current recommendations for this condition. This was a case of transverse diverticulitis in a man in his late 40’s who recovered with non-operative treatment. The widespread use of computerized tomography (CT) scans makes diagnosing diverticular disease relatively simple, but treatment is evolving. The case summarized here shows that less invasive measures can be used in treating both complicated and uncomplicated diverticular disease. After an uncomplicated in-patient admission for intravenous antibiotics, the patient was discharged in stable condition with a prescription for oral antibiotics and clinic follow-up. Classic medical school teaching concerning treatments for complicated and uncomplicated forms of diverticulitis have been updated but require further research testing.

Published: February 2021

CONTEXT To identify the presence of any correlative factors between presenting symptoms and characteristics of asymmetrical sensorineural hearing loss on audiogram, and if retrocochlear pathology was identified on MRI in patients presenting in a private practice setting. METHODS A retrospective study of patients meeting inclusion criteria who underwent MRI for asymmetric hearing loss between March 2014 to March 2017 was reviewed using Allscripts electronic health records. This data was then compiled in an excel spreadsheet and submitted for statistical analysis. RESULTS Of the initial 687 study patients, N = 303 patients met the inclusion criteria for review. Of these 303, 48 patients (15.8%) had abnormal MRI findings. Chi-square analysis performed showed no significant association of varied clinical variables (e.g. uni and bi-lateral tinnitus, vertigo, etc.) with abnormal MRI. Point Biserial Correlation analysis revealed no statistically significant correlations, with the exception of that between AS (Left Ear) 6 kHz and MRI lesions (r = -0.115, p = 0.045). Logistic and multinomial logistic regression analysis used to calculate odds ratios showed that for patients with hearing loss at the 6 kHz (dB) level, there is a very slightly lower, statistically significant likelihood of lesions showing up on MRI (OR, 0.984 (95% CI, 0.970-0.998), p = 0.0251). CONCLUSIONS The results lead to the conclusion that there may be an association between experiencing hearing loss at the level of 6 kHz and a slightly lower chance of the presence of retrocochlear lesion noted on MRI.
Inverted Papilloma of the Middle Ear and Mastoid Cavity: A Case Report, Literature Review, And Surveillance Proposal
Authors: Metz Christopher M. , Standring Robert T. , Babu Seilesh C. , Keller Christian E. 
Published: February 2021

INTRODUCTION TO THE TOPIC Inverted papilloma is a rare condition of the middle ear. In this paper, the authors present a case report of a patient at a Midwestern health system with inverted papilloma. To supplement the case report, a literature review was also performed to identify clinical trends predisposing such cases to recurrence, malignant transformation, and response to radiation. In addition, the authors also propose a surveillance algorithm derived from this case and previously published surveillance strategies. CASE REPORT The authors present a rare case of inverted papilloma of the middle ear. To the authors’ knowledge, this is the youngest case presentation (mid-teenage years) of this condition to have been reported in the literature. The patient underwent surgical excision, had recurrence, and has been disease free since revision surgery. SUMMARY OF THE EVIDENCE Our literature review identified 25 cases previously published with ours being the 26th. An inadequate number of cases exist to abstract statically relevant clinical trends in presentation and tumor behavior. Additionally, no tumor characteristics have been identified that predispose tumors to future malignant transformation. No assessments can be made regarding the benefits of radiation therapy. Most cases to date have been surveyed with a combination of CT, MRI, and clinical follow-up. CONCLUSIONS Inverted papillomas of the middle ear space are rare. Although this case report adds to the literature, additional cases are needed to draw statistically relevant clinical characteristics and responses to medical and surgical therapy.
Anatomic Evaluation of the Quadriceps Tendon in Cadaveric Specimens: Application for Anterior Cruciate Ligament Reconstruction Graft Choice
Authors: Krebs Nathan , Yaish Amjad , O'Neill Nicholas 
Published: February 2021

Purpose The quadriceps tendon (QT) is an autograft option for primary and revision anterior cruciate ligament (ACL) reconstruction. Techniques for predicting the appropriate graft size are limited. The purpose of this study was to evaluate the morphologic features of the QT in cadaveric specimens and compare the findings to recent MRI studies. Materials and Methods Macroscopic dissections were performed on 10 cadaveric knees. Using the distal myotendinous junction of the rectus femoris and superior pole of the patella as anatomic landmarks, the QT was isolated. Tendon length, width, and thickness were recorded at 10 millimeter (mm) increments. A central 80 mm x 10 mm graft was harvested, after which the graft was measured in an identical fashion. Specimen anthropometric data was collected. Subgroup analysis and linear regression were then performed using Microsoft Excel 2011 Office Analysis ToolPak. Results The mean QT length was 83.3 +/- 14.4 mm, ranging from 63 to 108 mm. The mean percentage of remaining QT volume following graft harvesting was 63.3%. QT length showed significant correlation with patient height (correlation coefficient: 0.719, p = 0.027). QT thickness remained relatively constant, while the width is greatest at its patellar insertion and gradually decreases proximally towards the myotendinous junction. Conclusion The QT has the anatomical features to produce a robust autograft for ACL reconstruction. During preoperative evaluation of graft size and quality, patient height should be considered as it is strongly correlated with the length of the potential graft. Our findings support the use of MRI as a way to preoperatively assess the QT as an autograft when performing an ACL reconstruction.

Published: February 2021

CONTEXT It is estimated that there are approximately 1,000 sudden cardiac events occurring daily outside of the hospital setting in the US. OBJECTIVES The objectives of this pilot project were to determine lay participants’ ability to remember the steps of hands-only cardiopulmonary resuscitation (HOCPR) following a 30-minute instructional session regarding proper technique and their willingness to perform bystander CPR (BCPR) on victims of sudden cardiac arrest outside in the community. SAMPLE AND SETTING A nine-item survey questionnaire that was created by the authors was first administered to a sample of 75 adults who had volunteered at their institutions’ emergency department. Inclusion criteria included all adults over the age of eighteen years. OUTCOME MEASURES To gauge whether basic HOCPR training improved bystander preparedness and willingness to provide assistance to a victim of sudden cardiac event. METHODS After IRB approval, participants were shown a one-minute video by the American Heart Association (AHA) and provided a 30-minute demonstration of key HOCPR skills on a mannequin. A post-instruction nine-item survey was sent by mail/email or administered by phone at one month after training to assess participants’ retention of HOCPR knowledge and attitude. RESULTS The initial survey responses showed 75 (100%) were able to recall the basic steps of HOCPR, with 59 (79%) “very likely” to help provide BCPR. Not needing to provide breaths made 57 (76%) of lay participants more willing to assist a person in need. A subgroup of 31 (41%) of the initial 75 participants were lost to follow-up. Out of the 44 (59%) who completed the one-month survey, 44 (100%) of participants remembered the primary HOCPR steps and technique. A subgroup of 32 (73%) one-month respondents indicated that they were more likely to assist victims if rescue breathing was not required, and 11 (25%) had reportedly tried to teach family and friends about HOCPR. CONCLUSIONS These results indicate that of those involved in the survey, the majority could recall the correct steps and be willing to provide HOCPR. These results could help in shaping community outreach and training programs designed to improve the rate and quality of response to victims of sudden cardiac arrest.
Introducing Osteopathic Curriculum for Family Medicine Physicians in a Community-based Allopathic Residency Program
Authors: Turnbull Jacob , Merck Dan , MacMillan Karri 
Published: February 2021

CONTEXT Will increased exposure to osteopathic medicine improve allopathic resident and attending physicians’ support of implementing an osteopathic curriculum in graduate medical education? The overall goal of this quality improvement project was to examine the familiarity and interest of allopathically-trained residents and attendings with osteopathic medicine before, and after, a brief educational workshop. METHODS Setting: Mercy Health Saint Mary’s Hospital in Grand Rapids, MI. Participants included a sample of 27 Family Medicine (FM) residents and attendings who had been trained in allopathic medical schools. First, a one-hour lecture on “Foundations of Osteopathic Medicine” was given. The lecture included a PowerPoint presentation followed by a 15-minute hands-on demonstration of osteopathic diagnosis and treatment. A pre and post-workshop survey modified from another larger study was administered to all attendees. Primary selected outcomes included percentage of allopathic resident participation in attendance and pre-post-workshop response differences. RESULTS Of the 31 allopathic residents in this community-based FM program, 23 (74.2%) were present for the lecture and completed both a pre and post-workshop survey. A total of 24 (78%) of participants had never attended a previous lecture on osteopathic medicine. Respondents’ overall attitude regarding the implementation of an osteopathic curriculum was generally positive after the workshop. Of the 27 participants (23 residents and four attendings) surveyed before the lecture, 23 (85.2%) were initially interested in learning how to perform osteopathic manual treatment (OMT), this increasing to 25 (92.6%) after the workshop. The Mercy Health FM resident respondents were initially first supportive of osteopathic medicine at 59.3%, improving to 77.8% after completing the workshop. CONCLUSIONS These results suggest that many allopathically trained physicians may lack exposure to osteopathic medicine principles. In this allopathic-oriented residency sample setting, a relatively brief workshop increased attendees’ interest in osteopathic medicine. Results suggest that initial and refresher exposure to osteopathic medicine content and OMT practices during residency curricula can be used to elicit support from allopathically-trained resident physicians.
Climate benchmarks and input parameters representing locations in 68 countries for a stochastic weather generator, CLIGEN
Authors: Fullhart Andrew T. , Nearing Mark A. , Armendariz Gerardo , Weltz Mark A. 
Published: February 2021

Abstract. This dataset contains input parameters for 12 703 locations around
the world to parameterize a stochastic weather generator called CLIGEN. The
parameters are essentially monthly statistics relating to daily
precipitation, temperature, and solar radiation. The dataset is separated
into three sub-datasets differentiated by having monthly statistics
determined from 30-, 20-, and 10-year record lengths. Input
parameters related to precipitation were calculated primarily from the NOAA
GHCN-Daily network. The remaining input parameters were calculated from
various sources including global meteorological and land-surface models that
are informed by remote sensing and other methods. The new CLIGEN dataset
includes inputs for locations in the US, which were compared to a
selection of stations from an existing US CLIGEN dataset representing
2648 locations. This validation showed reasonable agreement between the two
datasets, with the majority of parameters showing less than 20 %
discrepancy relative to the existing dataset. For the three new datasets,
differentiated by the minimum record lengths used for calculations, the
validation showed only a small increase in discrepancy going towards shorter
record lengths, such that the average discrepancy for all parameters was
greater by 5 % for the 10-year dataset. The new CLIGEN dataset has the
potential to improve the spatial coverage of analysis for a variety of
CLIGEN applications and reduce the effort needed in preparing climate
inputs. The dataset is available at the National Agriculture Library Data

O presente relato de pesquisa apresenta o desenvolvimento de um trabalho que, por meio de aulas para turmas-piloto, proporcionou um contato de acadêmicos com alunos antes de se adentrar no campo de estágio. A pesquisa descrita foi realizada no ano de 2005, com 13 acadêmicos do terceiro ano do curso de Ciências Biológicas da Universidade Estadual de Ponta Grossa (UEPG), no Paraná. Os principais objetivos foram: avaliar o impacto resultante da vivência das aulas para turmas-piloto na formação docente e verificar se alguns dos encaminhamentos teórico-metodológicos trabalhados nas disciplinas de Didática e Estágio Supervisionado em Biologia revelavam-se nos procedimentos dos acadêmicos durante a realização da prática em questão. Para tanto, utilizou-se a abordagem de pesquisa qualitativa, de natureza interpretativa. A metodologia abrangeu três momentos para registro e análise do material empírico, obtido através do trabalho com a tematização da prática: ação, reflexão, ação. Os principais resultados apontam para uma melhora significativa nas aulas ministradas pelos acadêmicos após a reflexão sobre a prática, pois possibilitaram aos licenciandos a análise do trabalho docente frente à classe, permitindo o aprimoramento das práticas de ensino. Palavras-Chave: Estágio supervisionado. Didática. Formação de professores. This research report presents the development of a work which provided this kind of contact before the students´ training by teaching lessons to pilot classes. The research was developed in 2005 by 13 trainees from the 3º serie of Biologycal Sciences course at Universidade Estadual de Ponta Grossa (UEPG) - State of Paraná. The main objectives were: to evaluate the impact for academic students formation as a result of the lessons taught to pilot classes and verify if some theoretical and methodologic procedures worked during Didactics and Biology Teaching Practice lessons have appeared during the mentioned practice. For this purpose a qualitative approach research was used, through an interpretative nature. The methodology for registration and analysis of the empirical material collected was divided into three moments: action, reflexion, action. The results pointed to significative improvement in lessons taught by students after the reflexion about their practice because it permited an analysis of the teaching work in front of the classes, allowing teaching practices improvement.

Seismic resistance of reinforced concrete-masonry shear walls with high steel percentages
Authors: Priestley M. J. N. 
Published: February 2021

This paper summarizes test results of six heavily reinforced concrete masonry shear walls. The test programme was designed to investigate the necessity for the low ultimate shear stress specified by Masonry codes. Care was taken to accurately model good, but realistic design practice in detailing, and variables investigated in the series included steel percentage, influence of vertical load and confinement of potential crushing areas by mortar bed confining plates.
Results are presented which clearly indicate that the maximum current code allowance for ultimate shear stress is unreasonably low. No wall suffered diagonal shear failure despite maximum shear stresses exceeding four times the maximum code level. All walls displayed stable hysteresis loops at a displacement ductility factor of 2, and the less heavily reinforced walls (designed to approximately twice code levels) were satisfactory at  DF = 4. Degradation was never catastrophic and occurred due to slip of the entire wall along the foundation beam. Methods for reducing the degradation are discussed. Confining plates did not significantly reduce the degradation of the hysteresis loops, but substantially reduced damage to the walls  at high ductility factors.
Values of required ductility for walls designed to the Loadings Code are investigated, and on the basis of these and the experimental results, recommendations are made for relaxation to the ultimate shear provisions of the masonry code.
Dynamic tests on PTFE sliding layers under earthquake conditions
Authors: Tyler R. G. 
Published: February 2021

The first part of a programme to assess the characteristics of PTFE sliding bearings during earthquake motions is described. Tests were performed on pure PTFE elements sliding on stainless steel. Representative normal loads were applied together with a sliding action, giving a maximum acceleration of 0.2 g and a maximum velocity of 38 cm/sec, i.e. motions equivalent to a moderate to severe earthquake.
At 0°C friction was found to have maximum coefficients which fell from 17 to 13% as the normal pressure was increased from 15 to 25 MN/m2. At 20°C corresponding values were reduced to 15 and 10%. Maximum friction generally occurred in the first cycle of loading after which values fell. After 5 cycles the range was typically 9 to 5%.
Tests on lubricated PTFE layers showed coefficients of friction less than 2% under the above test conditions; the maintenance of this low value over the years would depend on the effective retention of the grease.
It is possible that, by careful design of bearings for higher pressures, and utilizing filled PTFE materials, lower overall friction values for the dry condition may be achieved.
Multidirectional seismic response of a curved highway bridge model
Authors: Williams D. , Godden W. G. 
Published: February 2021

A continuing experimental model study relating to the seismic resistance of large multi-span curved overcrossings is reported.
A brief description of the microconcrete model, a 1/30 true-scale version of a hypothetical prototype, which was tested on the 20 ft x 20 ft (6.1 m) Shaking Table at the University of California, is given. The response of the model is described for a series of simulated seismic excitations applied
(i) horizontally in the asymmetric longitudinal direction, and
(ii) horizontally in the symmetric direction, both alone and also with simultaneous vertical excitation.
The influence of expansion joint design on the seismic behaviour is the main parameter studied, with emphasis on the need for joint restrainers of adequate ductility, to effectively tie adjacent girders together. However, because of the severe damage caused by impacting at the expansion joints during moderately strong excitation, it is concluded that expansion joints should ideally be omitted from such structures.
