Integrating Cost As A Decision Variable In Wargames, Joshua N. Reese, Jonathan D. Ritschel, Brent T. Langhals, Ryan D. Engle

Faculty Publications

The US military can no longer afford to be reactive, leaving critical cost analyses to the months and years following operations or full-scale conflicts. By leveraging cost in wargaming as part of the Joint planning process, DOD can provide Congress and the American taxpayers a range of potential costs associated with various military engagements that reflect fiscal and operational realities.

“No Queremos Quedar Mal”: A Qualitative Analysis Of A Boundary Setting Training Among Latina Community Health Workers., Luis R. Alvarez-Hernandez, J. Maria Bermudez, Pamela Orpinas, Rebecca Matthew, Alejandra Calva, Carolina Darbis

School of Social Work Faculty Publications

Community health workers (CHWs)—or promotoras de salud in Spanish—have successfully addressed the health needs of Latinx and immigrant populations. However, for promotoras, setting boundaries is particularly difficult given challenges like residing in the same communities as their participants. The purpose of this study was to describe the development and impact of a boundary setting training to support the emotional well-being of immigrant promotoras. The training (four 1-hr sessions) was informed by social cognitive theory and a Chicana feminist framework. The promotoras who participated in the training helped create Lazos Hispanos, a community-based participatory research (CBPR) study and CHW …

Mitral Valve Repair Complicated By Left Circumflex Coronary Artery Occlusion: The Vital Role Of The Anesthesiologist, Andres Bacigalupo Landa, Jason Hoyos, Jayanand D'Mello

Faculty, Staff and Students Publications

The anatomical relationship between the mitral valve and the left circumflex coronary artery places this vessel at risk for occlusion during mitral valve repair or replacement. In view of the potential high morbidity and mortality of this complication, the anesthesiologist has a vital role in its prompt diagnosis. We present the case of a 47-year-old man who underwent a minimally invasive mitral valve repair, which was complicated by left circumflex coronary artery occlusion.

A New Aortic Arch Dissection Classification: The Fuwai Classification, Juntao Qiu, Xinjin Luo, Jinlin Wu, Wei Pan, Qian Chang, Xiangyang Qian, Xiaogang Sun, Bo Wei, Liang Zhang, Shen Liu, Wenxiang Jiang, Cuntao Yu

Faculty, Staff and Students Publications

Aims: We describe a new aortic arch dissection (AcD) classification, which we have called the Fuwai classification. We then compare the clinical characteristics and long-term prognoses of different classifications.

Methods: All AcD patients who underwent surgical procedures at Fuwai Hospital from 2010 to 2015 were included in the study. AcD procedures are divided into three types: Fuwai type Cp, Ct, and Cd. Type Cp is defined as the innominate artery or combined with the left carotid artery involved. Type Cd is defined as the left subclavian artery or combined with the left carotid artery involved. All other AcD surgeries are …

Single-Dose Del Nido Cardioplegia Compared With Standard Cardioplegia During Coronary Artery Bypass Grafting At A Veterans Affairs Hospital, Michael R Reidy, Ernesto Jimenez, Shuab Omer, Lorraine D Cornwell, Sabrina X Runbeck, Ourania Preventza, Gabriel Loor, Todd K Rosengart, Joseph S Coselli

The Texas Heart Institute Journal

Del Nido cardioplegic solution (DNC), used chiefly in pediatric patients, rapidly induces prolonged cardiac arrest during cardiac surgery. To determine whether surgical outcomes after coronary artery bypass grafting in a United States military veteran population differed when DNC was used instead of our standard Plegisol cardioplegia, we retrospectively reviewed 155 consecutive operations performed from July 2016 through June 2017. Del Nido cardioplegia was used to induce cardiac arrest in 70 patients, and Plegisol in 85. Compared with the Plegisol group, the DNC group had a shorter mean cardiopulmonary bypass time (96.8 vs 117 min; P48 hours, atrial fibrillation, tracheostomy, reintubation, …

Papillary Fibroelastoma In Differential Diagnosis Of Left Atrial Appendage Masses, Anthony Alozie, Annette Zimpfer, Andreas Erbersdobler, Felix G Meinel, Pascal M Dohmen, Alper Öner

The Texas Heart Institute Journal

Papillary fibroelastomas are benign tumors that usually originate from cardiac valves but may have other endocardial origins. We report the cases of 2 patients in whom left atrial appendage masses were initially diagnosed as thrombus. They were treated for embolic stroke and their symptoms resolved; however, their left atrial appendage masses did not regress. After surgery, histologic analysis of the resected masses revealed papillary fibroelastoma in both cases. We discuss the diagnostic and therapeutic dilemmas encountered in patients with papillary fibroelastomas and cardiac masses other than thrombus.

Benign Metastasizing Leiomyoma In The Heart Of A 45-Year-Old Woman, Mohamad Karnib, Isaac Rhea, Robin Elliott, Saneka Chakravarty, Sadeer G Al-Kindi

The Texas Heart Institute Journal

We report a rare case of benign metastasizing leiomyoma in the heart of a 45-year-old woman 2 years after a uterine leiomyoma had been discovered during hysterectomy. Computed tomograms at presentation showed a large mixed cystic mass in the pelvis and bilateral lung nodules suggestive of metastatic disease. A large cardiac mass, attached to the chordae of the tricuspid valve and later shown to be histopathologically consistent with uterine leiomyoma, was successfully resected through a right atriotomy. This case suggests that benign metastasizing leiomyoma should be considered in the differential diagnosis of right-sided cardiac tumors.

Cerebellar Coordination Of Neuronal Communication In Cerebral Cortex, Samuel S Mcafee, Yu Liu, Roy V Sillitoe, Detlef H Heck

Duncan NRI Faculty and Staff Publications

Cognitive processes involve precisely coordinated neuronal communications between multiple cerebral cortical structures in a task specific manner. Rich new evidence now implicates the cerebellum in cognitive functions. There is general agreement that cerebellar cognitive function involves interactions between the cerebellum and cerebral cortical association areas. Traditional views assume reciprocal interactions between one cerebellar and one cerebral cortical site, via closed-loop connections. We offer evidence supporting a new perspective that assigns the cerebellum the role of a coordinator of communication. We propose that the cerebellum participates in cognitive function by modulating the coherence of neuronal oscillations to optimize communications between multiple …

Pharmacologically Induced Ex Copula Ejaculation In Horses And Donkeys, Afroza Khanam, Ayman A Swelum, Firdous A Khan

Faculty, Staff and Students Publications

Pharmacologically induced ex copula ejaculation is a method used for collection of semen when the traditional methods of semen collection are not feasible. Common indications for this method include health issues that either preclude the physical act of mating or result in impaired erection and ejaculation. The method also offers an alternative when there is a lack of equipment and facilities required for semen collection using the conventional artificial vagina method. A variety of pharmacological protocols for ex copula ejaculation in stallions have been evaluated in both research and clinical settings with no serious side-effects reported. In general, these protocols …

Computer-Assisted Challenge Point Intervention For Residual Speech Errors., Tara Mc Allister Byun, Elaine R. Hitchcock, Jose Ortiz

Department of Communication Sciences and Disorders Faculty Scholarship and Creative Works

Purpose: This preliminary case series investigated the effects of biofeedback intervention for residual rhotic errors delivered within a modified challenge point framework. In the challenge point framework, practice difficulty is adaptively adjusted with the goal of enhancing generalization learning. This study more specifically evaluated the feasibility of a computer-mediated implementation of challenge point treatment for rhotic errors using a custom open-source software, the Challenge Point Program.

Method: Participants were five native English speakers, ages 7;3–15;5 (years; months), who had established but not generalized correct rhotic production in previous treatment; overall treatment duration was flexible. Treatment incorporated either electropalatographic …

Ideology And Institutions In The Evolution Of Capital, Katharina Pistor

Faculty Scholarship

In Capital and Ideology, Thomas Piketty poses the intriguing thesis that ideology, or ideas about how society should be governed, is a powerful determinant for how society will be governed-as long as we take advantage of historical switch points. In this review essay I challenge this thesis by pointing out that many powerful ideas have run aground because of countervailing institutional arrangements. Oftentimes, they are leftovers from earlier times that precede the change and are now strategically employed for reconstituting private wealth. Clearly, ideology and institutions are deeply intertwined. I credit Piketty for putting ideology on the map of …

Drivers Of Health Policy Adoption: A Political Economy Of Hiv Treatment Policy, Matthew M. Kavanagh, Kalind Parish, Somya Gupta

Georgetown Law Faculty Publications and Other Works

Why do some countries rapidly adopt policies suggested by scientific consensus while others are slow to do so? Through a mixed methods study, we show that the institutional political economy of countries is a stronger and more robust predictor of health policy adoption than either disease burden or national wealth. Our findings challenge expectations in scholarship and among many international actors that policy divergence is best addressed through greater evidence and dissemination channels. Our study of HIV treatment policies shows that factors such as the formal structures of government and the degree of racial and ethnic stratification in society predict …

Delegation, Administration, And Improvisation, Kevin Arlyck

Georgetown Law Faculty Publications and Other Works

Nondelegation originalism is having its moment. Recent Supreme Court opinions suggest that a majority of justices may be prepared to impose strict constitutional limits on Congress’s power to delegate policymaking authority to the executive branch. In response, scholars have scoured the historical record for evidence affirming or refuting a more stringent version of nondelegation than current Supreme Court doctrine demands. Though the debate ranges widely, sharp disputes have arisen over whether a series of apparently broad Founding-era delegations defeat originalist arguments in favor of a more stringent modern doctrine. Proponents—whom I call “nondelegationists”—argue that these historical delegations can all be …

Complicity And Lesser Evils: A Tale Of Two Lawyers, David Luban

Georgetown Law Faculty Publications and Other Works

Government lawyers and other public officials sometimes face an excruciating moral dilemma: to stay on the job or to quit, when the government is one they find morally abhorrent. Staying may make them complicit in evil policies; it also runs the danger of inuring them to wrongdoing, just as their presence on the job helps inure others. At the same time, staying may be their only opportunity to mitigate those policies – to make evils into lesser evils – and to uphold the rule of law when it is under assault. This Article explores that dilemma in a stark form: …

Constitutional Skepticism And Local Facts, Louis Michael Seidman

Georgetown Law Faculty Publications and Other Works

Are written constitutions evil? In his new book, Constitutional Idolatry and Democracy, Brian Christoper Jones argues that they are. He claims that written constitutions fail to unite societies, degrade democratic engagement, and obstruct necessary constitutional maintenance. This review of his book argues that he is mostly right about the effects of the American Constitution, but that the effects of other constitutions will vary depending upon local facts.

Arthur Linton Corbin, Gregory Klass

Georgetown Law Faculty Publications and Other Works

This chapter on Arthur Linton Corbin will appear in the forthcoming collection, Scholars of Contract Law. The chapter provides a brief summary of Corbin’s life, then discusses five topics: Corbin’s Socratic approach to the classroom and his introduction of the caselaw method at Yale; Corbin’s analytic approach, which was inspired by Hohfeld and is illustrated by Corbin’s definitions of “contract” and “consideration”; Corbin’s evolutionary theory of the common law, his understanding of the relationship between law and social mores, and his insistence that legal rules always be treated as mere “working rules”; Corbin’s occasional appeal, despite his general aversion …

Identification Of Deep-Intronic Splice Mutations In A Large Cohort Of Patients With Inherited Retinal Diseases, Xinye Qian, Jun Wang, Meng Wang, Austin D Igelman, Kaylie D Jones, Yumei Li, Keqing Wang, Kerry E Goetz, David G Birch, Paul Yang, Mark E Pennesi, Rui Chen

Faculty, Staff and Students Publications

High throughput sequencing technologies have revolutionized the identification of mutations responsible for a diverse set of Mendelian disorders, including inherited retinal disorders (IRDs). However, the causal mutations remain elusive for a significant proportion of patients. This may be partially due to pathogenic mutations located in non-coding regions, which are largely missed by capture sequencing targeting the coding regions. The advent of whole-genome sequencing (WGS) allows us to systematically detect non-coding variations. However, the interpretation of these variations remains a significant bottleneck. In this study, we investigated the contribution of deep-intronic splice variants to IRDs. WGS was performed for a cohort …

Power Washing Pulmonary Alveolar Proteinosis, Tiana R Endicott-Yazdani, Gary S Schwartz, Haiying Zhang, Randall L Rosenblatt, Puneet S Garcha

Faculty, Staff and Students Publications

Pulmonary alveolar proteinosis is an uncommon cause of insidious onset shortness of breath and hypoxemia. It is caused by an accumulation of surfactant within the alveoli. Left untreated, it can be fatal. Standard-of-care treatment is whole-lung lavage; however, in severe cases, the associated hypoxemia can be profound and single-lung ventilation would not be tolerated, potentially preventing a lifesaving treatment. Single cases using veno-venous extracorporeal membrane oxygenation to perform whole-lung lavage have been reported. Here we describe three patients with severe pulmonary alveolar proteinosis who were successfully treated with whole-lung lavage using veno-venous extracorporeal membrane oxygenation for oxygenation support.

Social media such as Twitter and Facebook produce vast amounts of posts related to the virus, vaccines, economics, and politics. In order to figure out how public opinion and sentiments are expressed during the pandemic, this work analyzes the long-term social posts from social media and conducts sentiment analysis on tweets within 12 months. Our findings show the trend topics of long-term social communities during the pandemic and express people’s attitudes towards …

Improving Student Confidence With Electronic Health Record Order Entry, Arindam Sarkar, Anjali Aggarwal, Larissa Grigoryan, Susan G Nash, Nidhi Mehrotra, Roger J Zoorob, William Y Huang

Faculty, Staff and Students Publications

INTRODUCTION: Despite near-universal utilization of electronic health records (EHRs) by physicians in practice, medical students in most ambulatory settings gain limited experience with placing EHR orders. In this study, an individual preceptor site investigated the usefulness of a targeted curriculum in improving students' EHR confidence and clinical reasoning skills.

METHODS: Family medicine clerkship students assigned to one community health center were invited to participate in this prospective, survey-based study. In their first week, students observed a preceptor performing EHR tasks. For the remainder of the 4-week clerkship, students utilized decision support tools, assigned a working diagnosis, entered unsigned orders in …

Theses and Dissertations

This purpose of this randomized controlled trial was to determine the effect of pre-procedural informational video for full mouth dental rehabilitation (FMDR) under general anesthesia (GA) on guardian knowledge, retention and anxiety. Guardians of patients presenting to Virginia Commonwealth University (VCU) School of Dentistry, Department of Pediatric Dentistry for consult appointments to receive FMDR under GA were randomly assigned to the experimental or control group. In the experimental group, subjects watched an informational video and received written and verbal instructions regarding the upcoming FMDR appointment. The control group received written and verbal instructions only. On the day of the surgery, …

Inclusive Academic Education & Vocationally-Oriented Transition Predictors’ Association With Post-Secondary Outcomes Of Youth With Intellectual And Developmental Disabilities, Joshua P. Taylor

Theses and Dissertations

Despite efforts through legislation to increase the engagement of individuals with intellectual and developmental disabilities (IDD) in competitive integrated employment (CIE) and post-secondary education, outcomes remain poor. However, recent policy has emphasized CIE as a preferred outcome and created new opportunities to engage individuals with IDD in post-secondary education. Likewise, research into the transition of youth with disabilities has revealed several predictors of post-school success including inclusive education and a variety of vocationally-oriented experiences. Previous research had not determined whether students with IDD received both inclusive academic education and vocational transition experiences or how these predictors might interact. The purpose …

Vaccination Equity By Design, Olatunde C.A. Johnson, Kristen Underhill

Faculty Scholarship

This Essay examines how states’ initial COVID-19 vaccine-distribution strategies tended to disadvantage populations of color, including Black, Latinx, and Native American communities. These dynamics resonate with “inverse equity” effects of other public-health innovations. We argue for a federal regulatory framework to reduce inequity-forcing effects during initial vaccine rollout.

Interactive Modules For Flight Training: A Review, Stephanie G. Fussell, Robert Thomas

Journal of Aviation/Aerospace Education & Research

The use of animation and video, combined with auditory and text components, to teach complex subjects can be beneficial to deepen understanding. A review of the literature was conducted to better understand how interactive learning modules can give flight students tools to enhance the learning process outside of traditional instruction. Instructional theories and educational environments were considered through the lens of designing course content for flight students. Several research questions were asked to guide the course of the research, all focused on how students learn a complex subject matter using interactive material. Guidelines and principles are discussed to ensure the …

Metatheme Analysis: A Qualitative Method For Cross-Cultural Research, Amber Wutich, Melissa Beresford, Cindi Sturtzsreetharan, Alexandra Brewis, Sarah Trainer, Jessica Hardin

Faculty Research, Scholarly, and Creative Activity

In recent years, there has been a florescence of cross-cultural research using ethnographic and qualitative data. This cutting-edge work confronts a range of significant methodological challenges, but has not yet addressed how thematic analysis can be modified for use in cross-cultural ethnography. Thematic analysis is widely used in qualitative and mixed-methods research, yet is not currently well-adapted to cross-cultural ethnographic designs. We build on existing thematic analysis techniques to discuss a method to inductively identify metathemes (defined here as themes that occur across cultures). Identifying metathemes in cross-cultural research is important because metathemes enable researchers to use systematic comparisons to …
