How politics constrain the public’s understanding of terrorism

Published: December 2022

Abstract
Far-right domestic terrorism is a major threat to US national security. Despite this reality, conservative policymakers have downplayed the threat of right-wing violence while arguing that far-left violence (from groups like Antifa) is a more pressing concern. Drawing on attribution theory and research on politically motivated reasoning, we suggest that politics constrain the American public’s understanding of terrorism by shaping casual attributions for it. Using data from an experiment within a national survey (n = 700), we examine how political views moderate attributions made for the actions of far-right, far-left, and Islamist terrorism. We find that causal attributions for terrorism depend on the type of terrorist considered, with external attributions (motivated by injustice or oppression) endorsed most strongly for Islamist terrorists and internal attributions (motivated by hate or evil) endorsed most strongly for far-right terrorists. Furthermore, political views moderate this effect such that people believe terrorism committed by politically aligned groups is motivated less by the internal characteristics of the terrorists and more by external factors. Taken together, these findings may help to explain partisan differences in moral outrage over politically motivated terrorism.

Abstract
Animal dimensions are essential indicators for monitoring their growth rate, diet efficiency, and health status. A computer vision system is a recently emerging precision livestock farming technology that overcomes the previously unresolved challenges pertaining to labor and cost. Depth sensor cameras can be used to estimate the depth or height of an animal, in addition to two-dimensional information. Collecting top-view depth images is common in evaluating body mass or conformational traits in livestock species. However, in the depth image data acquisition process, manual interventions are involved in controlling a camera from a laptop or where detailed steps for automated data collection are not documented. Furthermore, open-source image data acquisition implementations are rarely available. The objective of this study was to 1) investigate the utility of automated top-view dairy cow depth data collection methods using picture- and video-based methods, 2) evaluate the performance of an infrared cut lens, 3) and make the source code available. Both methods can automatically perform animal detection, trigger recording, capture depth data, and terminate recording for individual animals. The picture-based method takes only a predetermined number of images whereas the video-based method uses a sequence of frames as a video. For the picture-based method, we evaluated 3- and 10-picture approaches. The depth sensor camera was mounted 2.75 m above-the-ground over a walk-through scale between the milking parlor and the free-stall barn. A total of 150 Holstein and 100 Jersey cows were evaluated. A pixel location where the depth was monitored was set up as a point of interest. More than 89% of cows were successfully captured using both picture- and video-based methods. The success rates of the picture- and video-based methods further improved to 92% and 98%, respectively, when combined with an infrared cut lens. Although both the picture-based method with 10 pictures and the video-based method yielded accurate results for collecting depth data on cows, the former was more efficient in terms of data storage. The current study demonstrates automated depth data collection frameworks and a Python implementation available to the community, which can help facilitate the deployment of computer vision systems for dairy cows.

Published: December 2022

Abstract
Three experiments were conducted to determine the effects of increasing soybean meal (SBM) levels by replacing feed-grade amino acids (AA) in corn, corn dried distillers grains with solubles (DDGS), and corn-wheat midds-based diets on growth performance of late finishing pigs (n = 4,406) raised in commercial facilities. Across all experiments, pens of pigs were blocked by initial bodyweight (BW) and randomly assigned to 1 of 5 dietary treatments. All diets were formulated to contain 0.70% standardized ileal digestible (SID) Lys and varying amounts of feed-grade AA. All diets were formulated to meet or exceed minimum essential AA requirement estimates as a ratio to Lys. In Exp. 1, 1,793 pigs (initially 104.9 ± 4.9 kg) were fed corn-based diets and pens of pigs were assigned treatments with increasing SBM from 5% to 20%. Overall, average daily gain (ADG) and feed efficiency (G:F) improved (linear and cubic, P ≤ 0.02) as dietary SBM increased, with the greatest improvement observed as SBM increased from 5% to 8.75% and little improvement thereafter. In Exp. 2, 1,827 pigs (initially 97.9 ± 4.3 kg) were fed diets containing 25% DDGS with SBM levels increasing from 0% to 16%. Overall, feed efficiency marginally improved (linear, P ≤ 0.10) as SBM increased, with the greatest performance observed when diets contained 8% SBM and similar performance thereafter with 12 or 16% dietary SBM. In Exp. 3, 786 pigs (initially 96.7 ± 3.2 kg) were fed diets that contained 30% wheat midds and dietary SBM from 0% to 16%. Final BW of pigs increased (linear, P &lt; 0.05) and overall ADG and G:F improved (linear and cubic, P &lt; 0.05) as SBM increased. The combined results of the three experiments suggest that inclusion of at least 4% to 8% dietary SBM at the expense of feed-grade amino acids in corn-based diets with or without grain coproducts can improve growth performance of late-finishing (greater than 100 kg) pigs.

Abstract
The U.S. pork production system is sensitive to supply chain disruptions, including those that can create challenges of feed delivery and feed management during the event of a foreign animal disease outbreak. Therefore, the objective was to evaluate feeding strategies during a prolonged feed availability shortage in group-housed finishing pigs and assess the impacts on pig performance. A total of 1,407 mixed-sex pigs (92 ± 11 kg BW) were randomly allocated to one of five treatments across 60 pens (N = 12 pens per treatment, 22 pigs per pen) and were blocked by initial body weight (BW) within the replicate, over a 21-d test period. Treatments were fed for 14 d (P1), and thereafter all pens returned to ad libitum access to a standard commercial diet for 7 d (P2). Treatments included: 1) Pens fed ad libitum (CON); 2) Pens fed at 1.45X ME maintenance requirement daily of CON diet (1.45X); 3) Pens fed 2X ME maintenance requirement daily of CON diet (2X); 4) Tightened feeders to the lowest setting, fed ad libitum of CON diet (CF); and 5) whole corn kernels, fed ad libitum (WC). P1 and P2 BW and feed disappearance were recorded to calculate ADG, ADFI, and G:F. Data were analyzed with pen as the experimental unit and least-squares means values reported by treatment. Compared to CON, pens fed 1.45X, 2X, CF, and WC treatments had significantly reduced P1 ADG (1.09 vs. 0.02, 0.34, 0.72, 0.41 kg/d, respectively), ADFI (3.21 vs. 1.42, 1.90, 2.49, 2.40 kg/d, respectively) and G:F (P &lt; 0.05). During P2, ADG and G:F were increased (P &lt; 0.05) compared to CON across all treatments. However, ADFI increased only in the 2X, CF, and WC diet from the CON (P &lt; 0.05). Overall (days 0 to 21), all strategies attenuated BW, ADG, and ADFI (P &lt; 0.01) compared to CON. However, G:F was only reduced (P &lt; 0.01) in 1.45X and WC, but not 2X and CF (P &gt; 0.05) compared to CON. In conclusion, all strategies explored could extend feed budgets. Even though these strategies were successful, increased BW variability was reported with more restrictive strategies. Further, adverse pig behaviors and welfare implications needs to be considered in adopting any restrictive feeding strategy.

Abstract
Stable isotope ratio analysis of tree rings has been widely and successfully applied in recent decades for climatic and environmental reconstructions. These studies were mostly conducted at an annual resolution, considering one measurement per tree ring, often focusing on latewood. However, much more information could be retrieved with high-resolution intra-annual isotope studies, based on the fact that the wood cells and the corresponding organic matter are continuously laid down during the growing season. Such studies are still relatively rare, but have a unique potential for reconstructing seasonal climate variations or short-term changes in physiological plant properties, like water-use efficiency. The reason for this research gap is mostly technical, as on the one hand sub-annual, manual splitting of rings is very tedious, while on the other hand automated laser ablation for high-resolution analyses is not yet well established and available. Here, we give an update on the current status of laser ablation research for analysis of the carbon isotope ratio (δ13C) of wood, describe an easy-to-use laser ablation system, its operation and discuss practical issues related to tree core preparation, including cellulose extraction. The results show that routine analysis with up to 100 laser shot-derived δ13C-values daily and good precision and accuracy (ca. 0.1‰) comparable to conventional combustion in an elemental analyzer are possible. Measurements on resin-extracted wood is recommended as most efficient, but laser ablation is also possible on cellulose extracted wood pieces. Considering the straightforward sample preparation, the technique is therefore ripe for wide-spread application. With this work, we hope to stimulate future progress in the promising field of high-resolution environmental reconstruction using laser ablation.
Fitting In While Standing Out: Professional Identity Formation, Imposter Syndrome, and Burnout in Early-Career Faculty Physicians
Authors: Vaa Stelling Brianna E. , Andersen Carl A. , Suarez Diego A. , Nordhues Hannah C. , Hafferty Frederic W. , Beckman Thomas J. , Sawatsky Adam P. 
Published: December 2022

Purpose
Professional identity formation (PIF) is a dynamic process by which an individual internalizes the core values and beliefs of a specific profession. Within medical education, PIF begins in medical school and continues throughout training and practice. Transitions affect PIF, with a critical transition occurring between medical training and unsupervised practice. This study aims to characterize PIF during the transition from resident to early-career faculty physician and explores the relationship between PIF and burnout during this transition.

Method
The authors conducted a qualitative study using constructivist grounded theory. They conducted semistructured interviews with early-career faculty physicians (defined as practicing for ≤ 5 years) from the Department of Medicine, Mayo Clinic. Deidentified interview transcripts were processed through open and axial coding. The authors organized themes and identified relationships between themes that were refined through discussion and constant comparison with newly collected data. During data analysis, the authors identified self-determination theory, with the concepts of autonomy, competence, and relatedness, as a framework to support the organization and analysis of the data.

Results
Eleven early-career faculty physicians participated in the interviews. Their PIF was characterized by the dual desires to fit in and stand out. Striving for these desires was characterized by imposter syndrome, driving physicians to question their decision making and overall competence. Participants associated imposter syndrome and academic pressures with burnout. Autonomy support by the institution to pursue opportunities important for career development helped mitigate burnout and support PIF.

Conclusions
Early-career faculty physicians face identity challenges when transitioning from training to unsupervised practice, including striving to fit in and stand out. They link this tension to imposter syndrome, which they associated with burnout. Institutional awareness and support, including addressing structural and cultural contributors to imposter syndrome, are paramount as new faculty explore their identities and navigate new challenges.
Lumbar Plexus Nerve Blocks for Perioperative Pain Management in Cerebral Palsy Patients Undergoing Hip Reconstruction: More Effective Than General Anesthesia and Epidurals
Authors: Trionfo Arianna , Zimmerman Remy , Gillock Kelly , Budziszewski Ross , Hasan Aysha 
Published: December 2022

Background:
Hip reconstruction in patients with cerebral palsy (CP) is associated with. significant postoperative pain. However, adequate analgesia can be difficult to achieve. in this population due to spasticity, communication barriers, and postoperative. spasticity. Recently, multimodal pain management techniques such as epidurals and. regional nerve blocks have been described for postoperative pain control, but it is unclear if 1 technique is more beneficial. The purpose of this study was to compare the outcomes of different perioperative pain management techniques.

Methods:
This study is a retrospective review of a consecutive series of children with CP over a 5-year period at a single pediatric tertiary-care hospital who underwent hip reconstruction (proximal femoral osteotomy with or without a pelvic osteotomy). Patients were subdivided based on their anesthetic protocol into the following groups: general anesthesia alone (G), general anesthesia with an epidural (E), and general anesthesia with lumbar plexus block (LPB). Our primary outcome was cumulative postoperative narcotic consumption (converted to morphine equivalents). Secondary outcomes included length of stay (LOS), average postoperative heart rate, and pain scores. analysis of variance testing was utilized to compare differences between the groups.

Results:
Fifty-four patients who underwent hip reconstruction were included: 19 in the G group, 18 in the E group, and 17 in the LPB group. LOS was significantly higher in the E group compared with the G and LPB groups: F(2,51)=3.58, P=0.04. The average pain score was significantly lower in the LPB group compared with the others: F(2,51)=4.26, P=0.02. The average postoperative heart rate was significantly lower in the LPB group: F(2,51)=7.08, P<0.01. Postoperative narcotic consumption was significantly lower in the LPB group: F(2,51)=11.57, P<0.01.

Conclusion:
The LPB patients required the least amount of narcotics compared with the other groups. This, combined with a lower perioperative heart rate and shorter LOS would suggest these patients experienced less pain over the time of their in-patient stay. In comparison to general anesthesia alone and epidural anesthesia, lumbar plexus nerve blocks are an effective pathway for postoperative pain control after hip reconstruction in a CP population.

Authors: Hung Tun-Yu , Wu Kuan-Wen , Lee Chia-Che , Lin Sheng-Chieh , Kuo Ken N. , Wang Ting-Ming 
Published: December 2022

Background:
In children with severe hereditary multiple exostoses (HME), coxa valga, and hip subluxation are common deformities. The literatures related to surgical management and prevention of hip joint subluxation in HME are scarce. In this study, we aimed to investigate the efficacy of guided growth procedure to correct coxa valga and hip subluxation in HME patients.

Methods:
We retrospectively retrieved 12 patients who received guided growth procedures for coxa valga and hip subluxation in HME patients with proximal femur exostoses with a minimum follow-up time of 2 years between 2012 and 2019. Radiographic parameters include head-shaft angle, Hilgenreiner-epiphyseal angle, acetabular index, Reimer migration percentage, center-edged angle, articulo-trochanteric distance, and femoral neck length for comparison between preoperative and latest follow-up results. It was conducted statistically by paired t test and Wilcoxon signed rank test.

Results:
In this study, the mean difference between preoperative and latest follow-up was significant in head-shaft angle (12±5 degrees; CI, 10-14; P<0.001), Hilgenreiner-epiphyseal angle (12±5 degrees; CI, 10-15; P<0.001), and MP (7%±8%; CI, 3-11; P=0.001). There was a low revision rate (4 of 21, 19%) and no complication in our study. Compared with previous studies on guided growth in children with cerebral palsy and developmental dysplasia of the hip, our study showed good comparable outcomes.

Conclusion:
The results indicated that guided growth improves the hip radiographic parameters of children with HME and may prevent coxa valga and hip subluxations. It is a safe procedure and provides predictable results.

Reconstruction of a Near-total Scalp Avulsion with NovoSorb Biodegradable Temporizing Matrix: Pediatric Case Report
Authors: Patel Niki K. , Tipps John A. , Graham Emily M. , Taylor Jesse A. , Mendenhall Shaun D. 
Published: December 2022

Summary:
Traumatic dog bites of the face and head are common among the pediatric population, although injuries resulting in total or subtotal scalp avulsions are rare and life-threatening. Standard treatment in these cases includes attempts at replantation or free tissue transfer; however, these procedures may not always be possible. An alternative treatment option involves the use of dermal substitutes, such as Integra (Integra LifeScience Corporation), with subsequent skin grafting. More recently, an alternative skin substitute called NovoSorb Biodegradable Temporizing Matrix (BTM) (PolyNovo North America LLC) has displayed favorable reconstructive outcomes in recent burn literature. NovoSorb BTM is a novel, fully synthetic bilayer scaffold made of biodegradable polyurethane matrix covered with a sealing membrane. In this report, the authors describe a 3-year-old boy who presented emergently with a severe dog bite avulsion to the subpericranial level of approximately 80% of his scalp, which was not replantable. The surgical plan involved a staged reconstruction using Integra and later skin grafting. Purulent infection ensued and required removal of Integra less than 2 weeks from application. Upon clearing of the infection, the wound was successfully closed with BTM and subsequent skin grafting. With proper wound management and over 6 months of follow-up, the patient experienced excellent healing of the graft with stable calvarial coverage and an acceptable aesthetic outcome. He will undergo tissue expansion of the remaining hair-bearing scalp in the future.
Assent in Pediatric Critical Care Research: A Cross-Sectional Stakeholder Survey of Canadian Research Ethics Boards, Research Coordinators, Pediatric Critical Care Researchers, and Nurses*
Authors: O’Hearn Katie , Cayouette Florence , Cameron Saoirse , Martin Dori-Ann , Tsampalieros Anne , Menon Kusum ,   the Canadian Critical Care Trials Group
Published: December 2022

OBJECTIVES:
Survey of four stakeholder groups involved in defining and obtaining assent for research in Canadian PICUs to better understand their perspectives and perceived barriers to assent.

DESIGN:
Cross-sectional survey.

SETTING:
Fourteen tertiary-care pediatric hospitals in Canada.

PARTICIPANTS:
Research Ethics Board Chairs, pediatric critical care nurses, research coordinators, and researchers.

INTERVENTIONS:
None.

MEASUREMENTS AND MAIN RESULTS:
A total of 193 participants responded. Thirty-seven percent (59/159) thought it was “Never/Almost Never” (59/159, 37%) feasible to obtain assent during the first 48 hours of PICU admission, and 112 of 170 (66%) indicated there are unique barriers to assent at the time of enrollment in PICU studies. Asking children for assent was most frequently rated as Important/Very Important for interviews/focus groups with the child (138/180, 77%), blood sample collection with a needle poke for research (137/178, 77%), and studies involving genetic testing with results communicated to the child/legal guardian (134/180, 74%). In two scenarios where a child and legal guardian disagreed about study participation, most respondents indicated that whether the child should still be enrolled would depend on the patient’s age (34-36%), and/or the risk of the study (24-28%). There was a lack of consensus over how the assent process should be operationalized, and when and for how long children should be followed to seek assent for ongoing study participation. Most stakeholders (117/158, 74%) thought that children should have the opportunity to decide if their samples could stay in a biobank once they are old enough to do so.

CONCLUSIONS:
There was an overall lack of consensus on the feasibility of, and challenges associated with, obtaining assent at the time of study enrollment and on how key aspects of the assent process should be operationalized in the PICU. This highlights the need for guidelines to clarify the assent process in pediatric critical care research.

Published: December 2022

Background.
The SherpaPak Cardiac Transport System is a novel technology that provides stable, optimal hypothermic control during organ transport. The objectives of this study were to describe our experience using the SherpaPak system and to compare outcomes after heart transplantation after using SherpaPak versus the conventional static cold storage method (non-SherpaPak).

Methods.
From 2018 to June 2021, 62 SherpaPak and 186 non-SherpaPak patients underwent primary heart transplantation at Stanford University with follow-up through May 2022. The primary end point was all-cause mortality, and secondary end points were postoperative complications. Optimal variable ratio matching, cox proportional hazards regression model, and Kaplan-Meier survival analyses were performed.

Results.
Before matching, the SherpaPak versus non-SherpaPak patients were older and received organs with significantly longer total allograft ischemic time. After matching, SherpaPak patients required fewer units of blood product for perioperative transfusion compared with non-SherpaPak patients but otherwise had similar postoperative outcomes such as hospital length of stay, primary graft dysfunction, inotrope score, mechanical circulatory support use, cerebral vascular accident, myocardial infarction, respiratory failure, new renal failure requiring dialysis, postoperative bleeding or tamponade requiring reoperation, infection, and survival.

Conclusions.
In conclusion, this is one of the first retrospective comparison studies that evaluated the outcomes of heart transplantation using organs preserved and transported via the SherpaPak system. Given the excellent outcomes, despite prolonged total allograft ischemic time, it may be reasonable to adopt the SherpaPak system to accept organs from a remote location to further expand the donor pool.
