Authors: Machaalani Rita , Vivekanandarajah Arunnjah , Despotovski Vanessa , Rodriguez Michael , Waters Karen A 
Published: December 2021

AbstractMorphological differences in the dentate gyrus (DG) have been reported in sudden unexpected deaths in infancy (SUDI), with the feature of focal granule cell (GC) bilamination (FGCB) reported as increased in unexplained SUDI, including sudden infant death syndrome (SIDS), compared with explained SUDI (eSUDI). However, it remains to be determined how these morphologies relate to each other and their extent along the anteroposterior length. This retrospective study evaluated the prevalence of FGCB, single or clustered ectopic GCs, granule cell dispersion (GCD), heterotopia, hyperconvolution, gaps, thinning, blood vessel dissection (BVD), and cuffing (BV cuffing), in an Australian SUDI cohort, and compared the prevalence of these features in eSUDI and unexplained SUDI. We analyzed 850 formalin-fixed paraffin-embedded serial and subserial sections of the hippocampus at the level of the lateral geniculate nucleus from 90 infants, and identified GCD in 97% of infants, single ectopic cells, hyperconvolution, thinning, and BVD in 60%-80%, heterotopia in 36%, gaps, clusters of ectopic cells and BV cuffing in 9%–15%, and FGCB in 18%. These features are clustered within 3–5 serial sections. The presence of FGCB correlated with single ectopic GCs and hyperconvolution. There were no differences in the prevalence of these features between unexplained SUDI (n = 74) and eSUDI (n = 16). Our findings highlight that DG morphological features are highly localized, extending 14–35 µm at their focal location(s) along the anteroposterior length. Consequently, multiple sections along the longitudinal extent are required to identify them. No feature differentiated SUDI from eSUDI in our cohort, thus we cannot conclude that any of these features are abnormal and it remains to be determined their functional significance.

Published: December 2021

Abstract
Diffusion tensor imaging (DTI) metrics are highly sensitive to microstructural brain alterations and are potentially useful imaging biomarkers for underlying neuropathologic changes after experimental and human traumatic brain injury (TBI). As potential imaging biomarkers require direct correlation with neuropathologic alterations for validation and interpretation, this study systematically examined neuropathologic abnormalities underlying alterations in DTI metrics in the hippocampus and cortex following controlled cortical impact (CCI) in rats. Ex vivo DTI metrics were directly compared with a comprehensive histologic battery for neurodegeneration, microgliosis, astrocytosis, and mossy fiber sprouting by Timm histochemistry at carefully matched locations immediately, 48 hours, and 4 weeks after injury. DTI abnormalities corresponded to spatially overlapping but temporally distinct neuropathologic alterations representing an aggregate measure of dynamic tissue damage and reorganization. Prominent DTI alterations of were observed for both the immediate and acute intervals after injury and associated with neurodegeneration and inflammation. In the chronic period, diffusion tensor orientation in the hilus of the dentate gyrus became prominently abnormal and was identified as a reliable structural biomarker for mossy fiber sprouting after CCI in rats, suggesting potential application as a biomarker to follow secondary progression in experimental and human TBI.
Attention Centrality and Audience Fragmentation: An Approach for Bridging the Gap Between Selective Exposure and Audience Overlap
Authors: Barnidge Matthew , Diehl Trevor , Sherrill Lindsey A , Zhang Jiehua 
Published: December 2021

Abstract
Scholarship on audience fragmentation typically takes one of two approaches: The micro-level analysis of individuals’ selective exposure to partisan news, or the macro-level analysis of audience overlap. To bridge the gap between these levels of analysis, we introduce the concept of attention centrality as a set of macro-to-micro measures that characterize how individual news media selection is situated within networks of public attention. Relying on an online panel survey conducted in the United States (N = 1,493), we examine the relationship between three indicators of respondents’ attention centrality (closeness, betweenness, and reach) and the partisan valence of their news selections. The study finds different patterns of results for the three indicators of attention centrality, indicating that partisan news media are not uniformly isolated to the periphery of public attention. Results are discussed in light of conversations about selective exposure and audience overlap in the United States and around the world.
Study on carbon nanotube/shape memory polymer composites and their applications in wireless worm actuator

Published: December 2021

Abstract
In this study, the surface of the carbon nanotubes was modified by chemical functionalization. The carbon nanotubes were placed in a mixed acid solution with a nitric acid-to-sulfuric acid volume ratio of 1:3. The results of the functionalization of the carbon nanotubes were investigated by controlling the reaction time. From the experimental results, the functionalized carbon nanotubes with a reaction time of 12 hours show good dispersibility. In the study of the essential characteristics of composite materials, it was observed that the tensile strength decreased with increase of carbon nanotube content. Compared with the result of the tensile strength test, it can be found that with increasing carbon nanotube content, the microwave heating and shape recovery speed are greatly improved. The experimental results show that the shape memory polymer composite with 4 wt% carbon nanotubes has the fastest microwave heating rate, so it takes only 2 minutes to achieve complete shape recovery. Finally, this study used shape memory polymer composites doped with 4 wt% carbon nanotubes as the driving end, combined with an elastic structure made of polyimide (PI) film using origami techniques to form a worm actuator. In the test, the system could move a distance of 6 mm forward during a microwave time of 1 minute. In addition, this research also constructed a physical model of shape memory polymer and explored the simple movement mechanism of the system.
Printing the Levellers: Clandestine Print, Radical Propaganda, and the New Model Army
Authors: Como David R 
Published: December 2021

Abstract
this article uses techniques of typographical analysis to identify the print houses that secretly produced the most important writings associated with the incipient ‘Leveller’ grouping as it took shape in 1646–47. It examines the key printers, Jane Coe and Thomas Paine, while illuminating the dynamics of the clandestine book trade of the 1640s. It then shows that these same printers acted as stationers of choice for the emergent New Model Army agitators, producing works such as the The Case of the Army Truly Stated and An Agreement of the People, among other titles. The resulting account sheds light on the origins and nature of the Leveller movement, and allows for discussion of the connections between the Levellers and the New Model Army. More broadly, this article highlights the centrality of printers as political protagonists and suggests that new modes of bibliographical analysis can address major problems in early-modern history.
Publications Produced by the Francis Galton Laboratory for National Eugenics
Authors: Cain Joe 
Published: December 2021

Abstract
In 1907, Karl Pearson created the Francis Galton Laboratory for National Eugenics at University College, University of London. His ambitions emphasised both discipline building and the assertion of primacy for university research in eugenics over political activism. An academic entrepreneur, Pearson operated the ‘Eugenics Laboratory’ as a publishing house or imprint. It published five series. Because titles in each series were printed as ad hoc private separates for much of their duration, current bibliographic records show considerable variation and error while historical studies of the Eugenics Laboratory tend toward fragmentation. This paper presents a comprehensive inventory for each series associated with the Eugenics Laboratory, and it offers brief analysis of emerging patterns. The series inventoried are: (1) Eugenics Laboratory Lectures, (2) Eugenics Laboratory Memoirs, (3) The Treasury of Human Inheritance, (4) Questions of the Day and of the Fray, and (5) Studies in National Deterioration.
Nurse Leader Breaks Through Glass Ceiling: Making History as First Air Force Nurse Major General (1999-2005)
Authors: Hughes Vickie , Sistrunk Katherine , Hughes Hallmon 
Published: December 2021

ABSTRACT

Introduction
There is a gap in the nursing literature about the significant contributions of executive military nurse leaders to the advancement of nursing as a profession and into interprofessional leadership roles. Many executive military nurse leaders have demonstrated the value of nursing leadership in non-traditional roles and paved the way to expand the leadership opportunities for nurses who would follow. The purpose of this study is to explore the personal stories, experiences, leadership strategies, and lessons learned through the eyes of the first nurse to achieve the rank of Major General in the U.S. Air Force.

Materials and Methods
The oral history method guided the exploration of participant memories and experiences. In compliance with the Oral History Association guidelines, the investigator obtained Institution Review Board permission, informed consent, and audiotaped interviews. An expert panel provided feedback on the appropriate language use in semi-structured interview questions with Air Force nurse executives. The oral history method provided a framework for the semi-structured interview and analysis. Active listening techniques such as exploration, clarifying, and paraphrasing helped foster deep listening. A graduate research assistant transcribed the 4-hour interview verbatim. The primary investigator emailed a copy of the transcript to the participant to verify accuracy and clarify content. Analysis involved examination and interpretation of the professional, military, nursing, and participant’s personal perspective to enhance historical understanding. Three independent coders extracted prevalent themes and subthemes during analysis.

Results
Repetitive major themes of courage, figuring it out, and winning others over emerged during data analysis. The major theme of courage has corresponding subthemes of tenacity, risk-taking, and re-writing the narrative. The major theme of figuring it out has subthemes of optimism, creativity, connectedness, learning, and managing change. Lastly, the winning others over theme has subthemes of emotional intelligence, teamwork, role-model/mentor, and moving from outsider to insider. The leadership strategies of taking calculated risks while remaining calm, being open to opportunities that she had never considered, and spending time learning new skills contributed to repeated advancement into higher leadership positions not previously held by a nurse within the U.S. Air Force.

Conclusion
The interview is packed full of leadership lessons that are just as relative today as 20 years ago. This presentation will conclude with a discussion of the most effective leadership strategies, the lasting impact of the leadership accomplishments, and current implications for nurse leaders today.

ABSTRACT

Background
Critical Care Air Transport Teams (CCATTs) play a vital role in the transport and care of critically ill and injured patients in the combat theater to include mechanically ventilated patients. Previous research has demonstrated improved morbidity and mortality when lung protective ventilation strategies are used. Our previous study of CCATT trauma patients demonstrated frequent non-adherence to the Acute Respiratory Distress Syndrome Network (ARDSNet) protocol and a corresponding association with increased mortality. The goals of our study were to examine CCATT adherence with ARDSNet guidelines in non-trauma patients, compare the findings to our previous publication of CCATT trauma patients, and evaluate adherence before and after the publication of the CCATT Ventilator Management Clinical Practice Guideline (CPG).

Methods
We performed a retrospective chart review of ventilated non-trauma patients who were evacuated out of theater by Critical Care Air Transport Teams (CCATT) between January 2007 and April 2015. Data abstractors collected flight information, oxygenation status, ventilator settings, procedures, and in-flight assessments. We calculated descriptive statistics to determine the frequency of compliance with the ARDSNet protocol before and after the CCATT Ventilator CPG publication and the association between ARDSNet protocol adherence and in-flight events.

Results
We reviewed the charts of 124 mechanically ventilated patients transported out of theater via CCATT on volume control settings. Seventy percent (n = 87/124) of records were determined to be Non-Adherent to ARDSNet recommendations predominately due to excessive tidal volume settings and/or high FiO2 settings relative to the patient’s positive end-expiratory pressure setting. The Non-Adherent group had a higher proportion of in-flight respiratory events. Compared to our previous study of ventilation guideline adherence in the trauma population, the Non-Trauma population had a higher rate of non-adherence to tidal volume and ARDSNet table recommendations (75.6% vs. 61.5%). After the CPG was rolled out, adherence improved from 24% to 41% (P = 0.0496).

Conclusions
CCATTs had low adherence with the ARDSNet guidelines in non-trauma patients transported out of the combat theater, but implementation of a Ventilator Management CPG was associated with improved adherence.

ABSTRACT

Background
Alcohol misuse poses significant public health concerns in the U.S. Military. An Alcohol Misconduct Prevention Program (AMPP), which includes a brief alcohol intervention (BAI) session, plus random breathalyzer program, has been shown to reduce alcohol-related incidents (ARIs) among Airmen undergoing training.

Purpose
The current study sought to examine whether a booster BAI administered at the end of Airmen’s training reduced ARIs out to a 1-year follow-up.

Methods
Participants were 26,231 U.S. Air Force Technical Trainees recruited between March 2016 and July 2018. Participants were cluster randomized by cohort to two conditions: AMPP + BAI Booster or AMPP + Bystander Intervention. The primary analysis was a comparison of the interventions’ efficacies in preventing Article 15 ARIs at a 1-year follow-up, conducted using a generalized estimating equations logistic regression model controlling for covariates.

Results
There was no significant difference by condition in Article 15 ARIs at the 1-year follow-up (P = .912).

Conclusions
Findings suggest that a booster may not be necessary to produce maximum effects beyond the initial AMPP intervention. It is also possible that alcohol behaviors changed as a result of the intervention but were not captured by our outcome measures. Future research should consider alternative outcomes or participant-tracking measures to determine whether a different or more intensive BAI booster is effective. The majority of Article 15 ARIs were for underage drinking; therefore, developing an intervention focused on this problem behavior could lead to large reductions in training costs in the military.
An Assessment of Physician Well-Being and Burnout Among Army Obstetricians and Gynecologists
Authors: Walther Devin M , Kraus Mark E , Beeken Kelly E , Pier Bruce D 
Published: December 2021

ABSTRACT

Introduction
Physician burnout is associated with unsafe patient care and poor patient satisfaction. Civilian studies show burnout rates of 46% among obstetricians/gynecologists (OB/GYNs). Army Active Duty (A-AD) physician burnout rates range from 7.7% to 26% across specialties, but no studies have assessed A-AD OB/GYN burnout. The objective of this study was to quantify well-being of A-AD OB/GYNs by determining rates of professional fulfillment (wellness) and burnout and detect factors of potential protective or risk for wellness and burnout.

Methods
A cross-sectional survey-based study was designed to determine well-being of A-AD OB/GYNs. This Institutional Review Board–approved study used the validated Professional Fulfillment Index. The survey was shared anonymously via email to 197 A-AD OB/GYNs. Additional questions asked as possible risk factors for burnout include location, training status, fellowship training, and remaining active duty service obligation (ADSO). Wellness and burnout rates were determined using published scales. Mean rates of wellness and burnout were reported, and chi-square tests detected associations between wellness/burnout and other variables.

Results
Eighty-three A-AD OB/GYNs responded to the survey (42%), with 73 available for full analysis. 26.5% had positive wellness, and 50% reported burnout. Completing fellowship training and shorter ADSO (of 0-2 years compared to &gt;5 years) had higher rates of wellness. There were no differences in burnout among groups.

Conclusions
Burnout rates in A-AD OB/GYNs appear higher than A-AD physicians of other specialties but are similar to civilian OB/GYNs. Fellowship training may confer higher rates of wellness. Further research is needed regarding improvements in A-AD OB/GYN well-being and burnout.
Occupational Injuries in Musicians: A Literature Review
Authors: Elam Trevor , Mowen Steven , Jonas Christopher 
Published: December 2021

ABSTRACT

Introduction
The U.S. Department of Defense employs more musicians than any other organization in the USA with over 6,000 musicians employed. Musculoskeletal pathologies, behavioral health disorders, hearing loss, and dystonias account for the majority of reasons a musician seek medical care. The aim of this study is to review recent medical literature documenting occupational hazards in musicians.

Materials and Methods
Authors performed a literature review of publications related to musician performance-related musculoskeletal disorders (PRMDs) and performance-related pain (PRP), behavioral health disorders, dystonias, and hearing loss, published from 2004 to 2019 PubMed.

Results
The search returned 174 possible articles which, after review and exclusion, yielded 88 articles.

Conclusions
Medical literature suggests several risk factors for multiple disease categories. Practice time and history of PRMD/PRP were both associated with development of PRMD/PRP and focal dystonia. A history of behavioral health disorder was associated with development of focal dystonia. Clinicians should counsel their musician patients on strategies to minimize risks, and additional research is needed to identify specific causes of illnesses in musician populations.
Lower Extremity Splinting: A Head-to-Head Comparison of A Novel One-Step Spray-on Splint Versus Standard Splinting

Published: December 2021

ABSTRACT

Introduction
Splinting is an essential component of treating many lower extremity musculoskeletal injuries; however, little development has been made in splinting technology. The purpose of this study is to evaluate the efficacy of current immobilization equipment for lower extremity fractures by testing a novel one-step spray-on foam splint (Fast Cast) against structural aluminum malleable (SAM) lower extremity musculoskeletal injuries and 6-inch ACE (3M Corp., Minneapolis, MN, USA) bandage splints.

Materials and Methods
Six orthopedic surgical residents and two medical students participated in a prospective analysis of austere splinting techniques and equipment that utilized a cadaveric model with a distal third tibia-fibula shaft fracture. Each participant was observed and scored by three fellowship trained attending orthopedic surgeons. All scoring was independent using a 5-point Likert scale based on 10 splinting criteria (50 total points possible), including quality of radiographic reduction, time to completion, safety, and sustain longitudinal traction. The Likert scale is a set of questions that reflects the respondent’s degree of agreement or disagreement with a statement. Each of the 10 questions has a range of 1-5. A score of 50 means the splint performed perfectly. The lowest possible score is a 10. The participants utilized standard equipment that included SAM splints and 6-inch ACE wraps (3M Corp., Minneapolis, MN, USA) in their first attempt. A second immobilization attempt was done with a one-step spray-on foam splint (Fast Cast). After each splinting attempt, the reduction was verified with radiographic imaging. Data analysis was performed using standard descriptive statistics, Student’s t-tests, and inter-rater reliability was calculated using Cronbach’s alpha scores. This project is Institutional Review Board (IRB) exempt.

Results
The one-step spray-on foam splinting technique was superior (P &lt; .05) in all parameters of the Likert scale, yielding a mean overall score of 45.1 points (±3.8), safety 4.7 points, longitudinal traction 4.5 points, and time 136 seconds (±23). The SAM resulted in a mean overall score of 33.8 points (±7.3), safety 2.8 points, longitudinal traction 4.1 points, and time 170 seconds (±52). Radiographic rating was 4.1 points (±0.7) for the SAM splint and 4.5 (±0.6) for Fast Cast. The differences in time to completion and radiograph rating did not reach statistical significance (P = .12 and P = .07, respectively).

Conclusion
A one-step spray-on foam splinting technique demonstrated consistent superiority in reducing fracture motion, potential soft-tissue damage, and sustained longitudinal traction as compared to the standard technique.
