Published: August 2023

AbstractWe describe a case of a previously irradiated infantile hemangioma in a patient 1 year of age. At the age of 78, the patient presented with a pink, pearly plaque at the previously irradiated infantile hemangioma site and was found to have a nodular basal cell carcinoma. [Correction added on 30 August 2023, after first online publication: In the preceding sentence, patient age has been corrected in this version] This case highlights the rare, but long‐term risks of radiation therapy for hemangiomas, but also presents an interesting historical vignette in dermatological treatments, with photographic documentation. It also represents the longest time interval between irradiation of an infantile hemangioma and the development of a basal cell skin cancer, 70 years in this case.

AbstractThe northeastern Siberian craton stores numerous placers of diamonds that differ in morphology and texture, and originate from different types of primary deposits, primarily kimberlites. Analyses of mantle zircons selected from samples of alluvial and coarse clastic sediments in the watersheds of the Olenek and Kyutyungde rivers in the Anabar‐Olenek subprovince of the Yakutian diamond province provide constraints on kimberlite magmatism events in the area. The new U–Pb ages and typical kimberlitic signatures of the Kyutyungde zircons trace‐element patterns reveal three main magmatic events that produced kimberlites: Middle Paleozoic (Late Devonian to Early Carboniferous), Jurassic and Triassic. The Jurassic zircons (177–149 Ma) are mainly related to kimberlites in the proximal Kuoika‐Molodo and Khorbusuon fields. Triassic zircons (240–221 Ma) were probably released during large‐scale erosion of the eastern Anabar shield, however, the presence of such zircons in the Kyutyungde area indicates that kimberlites of the respective magmatic stage may exist within the immediate vicinity of the area. The only Middle Paleozoic zircon sample (358.6 Ma, D3‐C1 boundary) may originate from a proximal kimberlite within the Kyutyungde area. The presence of Middle Paleozoic kimberlitic zircons, along with harzburgite–dunitic pyropes, indicates that the primary deposit of diamonds and related minerals may exist near or within the Kyutyungde area. Late Ediacaran–Early Cambrian (573–473 Ma) mantle zircons found in Early Cambrian conglomerates of the area, along with other mantle minerals including Cr spinel of a diamond assemblage, record another Precambrian event of potentially diamondiferous magmatism in the Kyutyungde basin.

AbstractBackgroundDisparities in suicide rates by veteran status are particularly striking for women. Veterans Crisis Line (VCL) is a preventive strategy.ObjectivesExamine the relationships and gender differences between VCL risk rating, and subsequent suicidal self‐directed violence (SSDV) in the 12‐months following VCL index call.MethodsCohort study of VCL callers in 2018.OutcomesDichotomized composite SSDV (non‐fatal suicide event and/or suicide) in the 12 months following VCL call.ResultsVeterans with high/moderate VCL risk had significantly higher odds of SSDV (OR = 4.02, 95% CI: 3.75, 4.30). There were no gender/VCL risk interaction (p = 0.3605). We also examined the association of gender, combination of VCL risk and suicide attempt (SA) history, on SSDV. Differential odds of SSDV for gender and combined VCL risk and SA history combinations were observed (p = 0.0005). Compared to those with lower VCL risk without SA history, those with high/moderate VCL risk with SA history showed higher odds of SSDV. Magnitude was higher for men, than for women veterans.Conclusions and RelevanceVeterans Crisis Line risk assessment performs relatively stable across the gender binary and highlights potential gender differences when factoring in SA history. Combining risk assessment and attempt history may lead to effective suicide prevention strategies.
Convergence of Phase-Averaged, Transitional Flow in an Abdominal Aortic Aneurysmal Model

Published: August 2023

Abstract
Abdominal aortic aneurysm can exhibit transitional flow characteristics in laminar flow regimes. To report transitional flow characteristics, we examined the convergence of phase-averaged solutions by executing blood flow simulations of a patient-specific abdominal aortic aneurysmal model for 257 cardiac cycles with periodic, pulsatile boundary conditions. The phase-averaged solutions were computed by averaging the solutions over various numbers of cardiac cycles and compared against the ones averaged over 124 cycles. The phase-averaged solutions reported small differences when they were averaged over a large number of cardiac cycles. The instantaneous solutions, however, failed to exhibit fluctuations reported in the phase-averaged solutions. To study transitional blood flows in the aneurysmal region, we need to report phase-averaged solutions as they exhibit nonperiodic, disturbed flow characteristics. Additionally, when reporting phase-averaged solutions, it is preferred to compute an average over a large number of cardiac cycles to be able to represent flow structures of the converged phase-averaged solutions.
Modeling, Feedforward Control, and Constrained Trajectory Generation for a Concrete Conveyance System

Published: August 2023

Abstract
Automated fabrication of concrete elements requires precise control of outgoing volume flow. Since measurements of the volume flow or the total extruded volume are challenging during production, a feedforward control is required, which in turn necessitates a model of the dynamics at hand. In this paper, a concrete conveyance system with two pumps is considered. These are mounted at the inlet and outlet of the hose, respectively. Based on previous work, a dynamical model with concentrated parameters is derived, which is motivated on the general distributed dynamics of two-phase flow. The model is validated by experiments, with parameters calculated by a tailored estimation approach. Based thereon, a feedforward control approach is presented and tested in simulation, exploiting the approximate flatness of the system. The flat parametrization is then used for constrained, smooth setpoint transition of the volume flow with minimal transition time.
One Nation, One Team: The U.S. Women’s National Team’s Equal Pay Victory and Its Broader Impact
Authors: Pincus Ben , Brown Martha , Lopes Alexia 
Published: August 2023

This teaching-based case study focuses on and addresses issues and opportunities in women’s sports. The context used for such discussions are the U.S. Women’s National Soccer team’s accomplishments (e.g., mainly the settlement for equal pay). Both the main case and the teaching materials enlighten examinations in three principal areas (i.e., leadership, diversity, and marketing). As future leaders in the sports industry, we believe that Sport Management students should be prompted to discuss issues and opportunities beyond what we have long referred to as (traditional) “sports,” to intentionally focus on and address issues and opportunities in women’s sports. Nonetheless, the benefits of the present case study reside in its ability to invite students to consider topics and current events in sports that are imperative to continue the momentum to move sports (in particular, women sports) forward. This teaching-based case study is intended for third- or fourth-year undergraduate students. Given its broad approach and focus in three different areas (i.e., leadership, diversity, and marketing), the case could be used in several sport courses, such as management or business of sports, sport marketing, sport diversity, sport sociology, or sport leadership. Knowledge is gained via individual and teamwork, class debates, and written assignments.
Bacteriophage populations mirror those of bacterial pathogens at sites of infection
Authors: Haddock N. L. , Barkal L. J. , Bollyky P. L. 
Published: August 2023

ABSTRACT

Bacteriophages, viruses that parasitize bacteria, are known to be abundant at sites of bacterial colonization, but the relationship between phages and bacteria at sites of infection is unclear. Bacteriophages are highly specific to their bacterial host species, and so we hypothesize that phage populations would mirror those of bacterial pathogens within infected tissues. To test this, here we study publicly available cell-free DNA (cfDNA) generated using next-generation sequencing of infected bodily fluids, including urine, joint fluid, peritoneal fluid, bronchoalveolar lavage fluid, cerebrospinal fluid, and abscess fluid, as well as uninfected control samples. These were analyzed using a computational pipeline for identifying bacteriophage sequences in cfDNA. We find that bacteriophage sequences are present in both infected and uninfected bodily fluids and represent a variety of bacteriophage morphologies and bacterial hosts. Additionally, phages from
Escherichia coli
,
Streptococcus
, and
Staphylococcus aureus
are overrepresented both in terms of proportion and diversity in fluids infected with these same pathogens. These data indicate that phages reflect the relative abundance of their bacterial hosts at sites of infection. Bacteriophage sequences may help inform future investigative and diagnostic approaches that utilize cell-free DNA to study the microbiome within infected tissues.

IMPORTANCE
Bacteriophages are an active area of investigation in microbiome research, but most studies have focused on phage populations at sites of bacterial colonization. Little is known about bacteriophage ecology at sites of active infection. To address this gap in knowledge, we utilized a publicly available data set to study bacteriophage populations in cell-free DNA collected from sites of infection. We find that phages reflect the relative abundance of their bacterial hosts at sites of infection. These studies may lead to future investigative and diagnostic approaches that incorporate phages as well as bacterial cell-free DNA.

Giant Spatial Redistribution of Electrons in a Wide Quantum Well Induced by Quantizing Magnetic Field

Published: August 2023

In samples of field-effect transistors based on GaAs/AlGaAs heterostructures with an electron system in a single 50-nm-wide GaAs quantum well, a transition stimulated by a quantizing magnetic field has been detected from a bilayer state of the system in zero magnetic field to a single-layer state when only the lowest Landau level is filled. In contrast to the results for the 60-nm-wide quantum well obtained in [S. I. Dorozhkin, A. A. Kapustin, I. V. Fedorov, V. Umansky, and J. H. Smet, Phys. Rev. V 102, 235307 (2020)], the single-layer state is observed not only in incompressible quantum Hall effect states of the electron system at filling factors of 1 and 2, but also in compressible states between these filling factors. The spatial location of the single-layer system in the quantum well has been established; it appears to be independent of the electron distribution over the layers in a low magnetic field. A possible qualitative explanation for this observation has been proposed. The detected transition is supposedly due to the negative compressibility of two-dimensional electron systems caused by exchange-correlation contributions to the electron−electron interaction.

ObjectiveTo build a supervised machine learning-based classifier, which can accurately predict whether Tai Chi practitioners may experience knee pain after years of exercise.DesignA prospective approach was used. Data were collected using face-to-face through a self-designed questionnaire.SettingSingle centre in Shanghai, China.ParticipantsA total of 1750 Tai Chi practitioners with a course of Tai Chi exercise over 5 years were randomly selected.MeasuresAll participants were measured by a questionnaire survey including personal information, Tai Chi exercise pattern and Irrgang Knee Outcome Survey Activities of Daily Living Scale. The validity of the questionnaire was analysed by logical analysis and test, and the reliability of this questionnaire was mainly tested by a re-test method. Dataset 1 was established by whether the participant had knee pain, and dataset 2 by whether the participant’s knee pain affected daily living function. Then both datasets were randomly assigned to a training and validating dataset and a test dataset in a ratio of 7:3. Six machine learning algorithms were selected and trained by our dataset. The area under the receiver operating characteristic curve was used to evaluate the performance of the trained models, which determined the best prediction model.ResultsA total of 1703 practitioners completed the questionnaire and 47 were eliminated for lack of information. The total reliability of the scale is 0.94 and the KMO (Kaiser-Meyer-Olkin measure of sampling adequacy) value of the scale validity was 0.949 (>0.7). The CatBoost algorithm-based machine-learning model achieved the best predictive performance in distinguishing practitioners with different degrees of knee pain after Tai Chi practice. ‘Having knee pain before Tai Chi practice’, ‘knee joint warm-up’ and ‘duration of each exercise’ are the top three factors associated with pain after Tai Chi exercise in the model. ‘Having knee pain before Tai Chi practice’, ‘Having Instructor’ and ‘Duration of each exercise’ were most relevant to whether pain interfered with daily life in the model.ConclusionCatBoost-based machine learning classifier accurately predicts knee pain symptoms after practicing Tai Chi. This study provides an essential reference for practicing Tai Chi scientifically to avoid knee pain.

ObjectiveOur study explored the impact of the COVID-19 pandemic on the food environment from the perspective of the urban poor and food vendors.DesignThis was a qualitative study conducted during September 2020 and February 2021.SettingThe study was carried out in two purposively selected informal settlements of Dhaka City, Bangladesh.ParticipantsWe conducted 21 in-depth interviews with residents of informal settlements and 10 key informant interviews with food vendors and food aid workers.ResultThe availability of staple foods was not disrupted during the pandemic but some perishables foods became more expensive due to supply chain disruptions and increased transportation costs. Limited market hours affected market access and mobility restrictions adversely affected local vendors. Cart vendors selling perishables incurred business losses they could ill afford. Demand for food reduced as employment disruption lead to reduced purchasing power and, therefore, reduction of quantity, quality and desirability of foods purchased. Respondents reported skipping meals and going hungry. The aid received was considered inadequate to meet needs.ConclusionThe food environment of the urban poor was disrupted from both supply and demand sides and the organisational response (both government and non-government) was severely inadequate. The social safety net needs to be extended and redesigned to ensure food security and health for the urban working poor in the future.
Effect of price and income on the demand for sugar-sweetened beverages in Nigeria: an analysis of household consumption data using an almost ideal demand system (AIDS)
Authors: Darsamo Vanessa , Walbeek Corne 
Published: August 2023

ObjectivesTo estimate the own-price, cross-price and income elasticities for carbonated soft drinks (CSDs), malt drinks, chocolate powder, sachet water and sugar in Nigeria. These elasticities can be used to estimate the potential demand response to the recently-introduced sugar tax in Nigeria.SettingThe study uses household data from the 2018/2019 Nigeria Living Standards Survey (NLSS).ParticipantsThe NLSS is a national household survey. 21 114 households were included in the final sample for this analysis.Primary and secondary outcomesWe used Deaton’s almost ideal demand system, which controls for the goods’ quality, to estimate the effect of price and income changes on the demand for CSDs, chocolate powder, malt drinks, sachet water and sugar.ResultsWe found that the own-price elasticity (ordered from most to least price-responsive) was −0.99 (p<0.01) for sachet water, −0.76 (p<0.01) for CSDs, –0.72 (p<0.01) for chocolate powder, −0.62 (p<0.01) for sugar and –0.19 (p<0.01) for malt drinks. The cross-price elasticities indicate that malt drinks and chocolate powders are substitutes of CSDs. The income elasticities indicate that all the commodities are normal goods. Sachet water had the highest income elasticity at 0.62 (p<0.01), followed by chocolate powder at 0.54 (p<0.01), CSDs at 0.47 (p<0.01), malt drinks at 0.43 (p<0.01) and sugar at 0.13 (p<0.01).ConclusionEven though the price elasticities for CSDs, malt drinks and chocolate powder are less than one, in absolute terms, they are significantly different from zero. Increases in the sugar-sweetened beverage tax could curb the demand for these beverages, and, in turn, reduce the incidence and prevalence of sugar-attributable diseases.

BackgroundIntrasaccular flow-disrupting devices are a safe and effective treatment strategy for intracranial aneurysms. We utilized high-frequency optical coherence tomography (HF-OCT) and digital subtraction angiography (DSA) to evaluate SEAL Arc, a new intrasaccular device, and compare the findings with the well-established Woven EndoBridge (WEB) device in an animal model of saccular aneurysms.MethodsIn a rabbit model, elastase-induced aneurysms were treated with SEAL Arc (n=11) devices. HF-OCT and DSA were performed after implant and repeated after 12 weeks. Device protrusion and malapposition were assessed at implant time and scored on a binary system. Aneurysm occlusion was assessed at 12 weeks with the WEB Occlusion Scale and dichotomized to complete (A and B) or incomplete (C and D) occlusion. The percentage of neointimal coverage after 12 weeks was quantified using HF-OCT. We compared these data to previously published historical controls treated with the gold-standard WEB device (n=24) in the same model.ResultsAneurysm size and device placement were not significantly different between the two groups. Complete occlusion was demonstrated in 80% of the SEAL Arc devices, which compared favorably to the 21% of the aneurysms treated with WEB devices (P=0.002). Neointimal coverage across SEAL Arc devices was 86±15% compared with 49±27% for WEB (P=0.001). Protruding devices had significantly less neointimal coverage (P<0.001) as did incompletely occluded aneurysms (P<0.001). Histologically, all aneurysms treated with SEAL Arc devices were completely healed.ConclusionComplete early aneurysm occlusion was frequently observed in the SEAL Arc treated aneurysms, with significant neointimal coverage after 12 weeks.
Field observed GCL panel shrinkage for five GCLs in composite liners

Published: August 2023

Field observed shrinkage was quantified and compared for one geosynthetic clay liner (GCL) type left covered only by a black geomembrane, a white geomembrane, and 0.3 m of gravel cover. Shrinkage is reported for up to 28 months field exposure of an additional four GCLs beneath a black geomembrane. All GCLs were needle-punched geotextile encased: one containing fine granular bentonite, two with powdered bentonite, one with polymer amended granular bentonite, and one multicomponent GCL with a film coating installed film up. All the GCLs examined have the potential to shrink with the magnitude of the shrinkage primarily dependent on the thermal/moisture cycles to which it is subjected and the degree of adhesion between panel overlaps. It is shown that the panel overlap adhesion can be highly variable and this is primarily attributed to condensation of water vapour below geomembrane wrinkles during daily thermal cycles. With a an initial GCL overlap of 300 mm, the shrinkage observed over 28 months left ≥32% of the original overlap; however, if the overlap had been only 150 mm, then gaps or ineffective seams would have occurred for several GCLs. Guidance regarding mitigating GCL panel shrinkage is provided.
