Abstract
Background and study aims Killian-Jamieson diverticulum (KJD) is a rare type of esophageal diverticulum that occurs in a specific area called the Killian-Jamieson space. Although surgery has been the conventional treatment for symptomatic KJD, minimally invasive endoscopic techniques, particularly Killian-Jamieson per-oral endoscopic myotomy (KJ-POEM), have emerged as an alternative. The aim of the study was to evaluate the effectiveness and safety of KJ-POEM in treating KJD.
Patients and methods This was an international, multicenter, retrospective study that included patients who underwent KJ-POEM for symptomatic KJD from October 16, 2018 to April 12,2023. The primary outcome was clinical success, defined as complete or near-complete resolution of symptoms (i.e., post-procedure Kothari-Haber Score ≤ 2).  Secondary outcomes were technical success (defined as successful completion of all procedural steps), rate and severity of adverse events (AEs), total procedure duration, and symptom recurrence during follow-up.
Results A total of 13 patients (mean age 65.23 years, 6 female) with KJD and a mean pre-procedure Kothari-Haber Score of 6 (standard deviation [SD] 2.16) underwent KJ-POEM across 10 participating centers. Clinical success and technical success were achieved in all cases (100%) with a mean post-procedure Kothari-Haber Score of 0.91 (SD 0.99). There were no AEs and no cases of injury to the recurrent laryngeal nerve. Mean length of hospital stay was 1.09 days (SD 0.74). Mean follow-up time was 9.41 months (SD 10.07) post-procedure. There was no post-procedure symptom recurrence any patient.
Conclusions KJ-POEM is a safe and effective alternative treatment for symptomatic KJD with excellent short/mid-term outcomes.

Abstract
Objectives This study aimed to pilot an application-based patient diagnostic questionnaire (PDQ) and assess the concordance of the admission diagnosis reported by the patient and entered by the clinician.
Methods Eligible patients completed the PDQ assessing patients' understanding of and confidence in the diagnosis 24 hours into hospitalization either independently or with assistance. Demographic data, the hospital principal problem upon admission, and International Classification of Diseases 10th Revision (ICD-10) codes were retrieved from the electronic health record (EHR). Two physicians independently rated concordance between patient-reported diagnosis and clinician-entered principal problem as full, partial, or no. Discrepancies were resolved by consensus. Descriptive statistics were used to report demographics for concordant (full) and nonconcordant (partial or no) outcome groups. Multivariable logistic regressions of PDQ questions and a priori selected EHR data as independent variables were conducted to predict nonconcordance.
Results A total of 157 (77.7%) questionnaires were completed by 202 participants; 77 (49.0%), 46 (29.3%), and 34 (21.7%) were rated fully concordant, partially concordant, and not concordant, respectively. Cohen's kappa for agreement on preconsensus ratings by independent reviewers was 0.81 (0.74, 0.88). In multivariable analyses, patient-reported lack of confidence and undifferentiated symptoms (ICD-10 “R-code”) for the principal problem were significantly associated with nonconcordance (partial or no concordance ratings) after adjusting for other PDQ questions (3.43 [1.30, 10.39], p = 0.02) and in a model using selected variables (4.02 [1.80, 9.55], p < 0.01), respectively.
Conclusion About one-half of patient-reported diagnoses were concordant with the clinician-entered diagnosis on admission. An ICD-10 “R-code” entered as the principal problem and patient-reported lack of confidence may predict patient–clinician nonconcordance early during hospitalization via this approach.

Published: September 2024

Abstract
Background Nationwide trends in the utilization of catheter-directed therapies for deep vein thrombosis and pulmonary embolism in the Medicare population are essential as they represent a major health care challenge. The annual incidence and mortality with venous thromboembolism are around 900,000 and 60,000 to 100,000 patients, respectively, in the United States.
Methods Data were acquired from the Data.CMS.gov website on Physician/Supplier Procedure Summary with a list of Medicare Part B fee-for-service claims from 2015 to 2021. Current Procedural Terminology codes 37187 (percutaneous venous mechanical thrombectomy) and 37212 (thrombolytic venous therapy) were queried for deep vein thrombosis. Similarly, Current Procedural Terminology codes 37184 (percutaneous arterial mechanical thrombectomy) and 37211 (thrombolytic arterial therapy) were queried for pulmonary embolism. Annual procedure counts, site of service, and self-reported specialty of the operator were recorded.
Results Overall, there was a trend toward increasing utilization of thrombectomy and decreasing utilization of thrombolysis procedures for both deep vein thrombosis and pulmonary embolism. Radiologists performed the majority of the catheter-directed therapy interventions for deep vein thrombosis, while radiologists and surgeons performed a similar number of catheter-directed therapy procedures for pulmonary embolism. Cardiologists were third in the catheter-directed therapy procedure count for both deep vein thrombosis and pulmonary embolism.
Conclusion An analysis of nationwide trends from 2015 to 2021 suggests increasing utilization of thrombectomy starting in 2020 when compared to thrombolysis for catheter-directed therapies for both deep vein thrombosis and pulmonary embolism procedures. Newer thrombectomy technologies may be one of the drivers of this shift from thrombolysis to thrombectomy.

Abstract
Objective The aim is to coat orthodontic brackets with two different bioactive materials and to compare the mechanical and morphological properties of coated brackets and tooth surfaces.
Materials and Methods A total of 120 stainless steel brackets were divided equally into three groups, that is, the uncoated brackets and nanohydroxyapatite (nHA)-coated, and nanobioactive glass (nBG)-coated brackets using a spin coater machine. The brackets were bonded on the enamel surface and underwent remineralization/demineralization cycles for days 1, 7, 14, and 30. At each time interval, the bond strength of the brackets was assessed using mechanical loading. An optical and scanning electron microscope (SEM) were used for surface evaluation, and the adhesive remanent index (ARI) values were obtained and quantified.
Statistical Analysis One-way analysis of variance using Tukey's test was used to compare the differences among the groups.
Results A uniform distribution of nanoparticles occurred on the surfaces of brackets. The shear bond strength (SBS) showed no significant differences in any tested groups on days 1, 7, and 14. However, control and nBG showed a significant difference from nHA at day 30. On days 7, 14, and 30, the nHA group showed the highest SBS values among the groups. For ARI, most samples showed an adhesive nature of failure at the enamel–brackets interface. The images confirmed the presence of coated particles on brackets and remnants of adhesives after SBS.
Conclusion This study confirmed that the nHA- and nBG-coated brackets have a high potential for application in orthodontics regarding structural and mechanical properties.

Abstract
Objectives This study aims to evaluate shear bond strength (SBS) of orthodontic brackets to enamel after resin infiltration pretreatment using different adhesive systems.
Materials and Methods Sixty extracted maxillary first premolars were divided into five groups (n = 12). Group I: sound enamel + Transbond XT; group II: resin-infiltrated enamel (ICON) + Transbond XT; group III: ICON + Scotchbond Universal Plus; group IV: ICON + Assure PLUS; group V: ICON + Transbond Plus Self Etching. The SBS was measured using universal testing machine and analyzed using analysis of variance (ANOVA). The adhesive remnant index (ARI) score after debonding was determined under stereomicroscope with a 10× magnification.
Statistical Analysis A one-way ANOVA and post hoc Tukey's test were used to compare the data. Further, the ARI scores were evaluated using a chi-squared test. The level of significance was set at p = 0.05.
Results SBS of group I, II, III, IV, and V were 11.70 ± 3.17, 11.23 ± 3.06, 9.52 ± 1.73, 8.97 ± 1.12, and 9.14 ± 0.70 MPa, respectively. SBS of group IV and V was significantly lower than group I and II (p < 0.05). There was no significant difference in the ARI scores among the five groups (p > 0.05).
Conclusion The SBS of enamel resin infiltration pretreatment depends on the adhesive system. The SBS of all groups was within adequate SBS range in clinical use. The most common ARI score was 2, which indicated lower risk of enamel fractures when debonding.

Published: September 2024

Abstract
Objectives This study aimed to investigate and compare water sorption and solubility properties of current restorative materials with different contents.
Materials and Methods Alkasite, self-adhesive restorative material (Cention N, Ivoclar Vivadent AG, Schaan, Liechtenstein), bulk-fill glass hybrid restorative material (EQUIA Forte HT, GC Corp., Tokyo, Japan), nanohybrid universal composite material (OptiShade, Kerr Dental, United States), and bulk-fill composite material (Filtek One Bulk Fill Restorative, 3M ESPE, St. Paul, Minnesota, United States) were used. Samples (n = 6) were prepared (2 × 10 mm) according to the ISO 4049 standards. Water sorption and solubility values were calculated according to the ISO 4049 standards.
Statistical Analysis One-way ANOVA, Tukey's post-hoc, Tamhane's T2 post-hoc, Pearson's correlation, and independent samples t-tests were used for statistical analysis (p < 0.05).
Results Group EQUIA Forte HT significantly showed the highest water sorption values (57.278 ± 3.174), while Group Filtek One Bulk Fill Restorative exhibited the lowest (4.429 ± 0.174; p < 0.05). The water sorption values for Group Cention N were 5.000 ± 0.542. Group EQUIA Forte HT significantly had the lowest water solubility values (−99.799 ± 1.909), while Group Cention N (−2.966 ± 0.402) significantly exhibited the highest (p < 0.05). There was no significant correlation between water sorption and solubility values for each material (p > 0.05).
Conclusion The bulk-fill nano-filled composite resin material was successful in terms of water sorption while the bulk-fill glass hybrid restorative system in terms of water solubility. Alkasite can be recommended to be used as a base material due to its high solubility feature. Monomer, filler type, and amount had an impact on the water sorption and solubility properties of the tested materials.

Background Transcatheter mitral valve repair is performed in a patient population at risk for thrombotic and bleeding events. The effects on platelet function and reactivity and their association with bleeding events after mitral transcatheter edge-to-edge therapy (M-TEER) have not been systematically examined.
Objectives We sought to investigate the association of different parameters of platelet function and thrombogenicity with bleeding events post M-TEER.
Methods In this single-center study, 100 consecutive patients with mitral regurgitation receiving TEER were analyzed. Blood was taken directly from the guide-catheter in the left atrium before and after placing the device. Blood samples were analyzed using impedance aggregometry (Multiplate) and TEG6s. The results were compared pre- and postprocedural. The primary outcome was any bleeding complication according to the Bleeding Academic Research Consortium classification within 6 months.
Results A total of 41 patients experienced bleeding events. TEG analysis showed a significant decrease in ADP aggregation and increase in ADP inhibition. In ROC-analysis, TEG ADP aggregation and inhibition and Multiplate ADP aggregation showed moderate predictive values for bleeding events. The delta-ADP-Test (Multiplate) showed the strongest prediction of bleeding (area under the curve: 0.69). Adding platelet function and TEG markers to a model of clinical bleeding risk factors improved the prediction for bleeding events.
Conclusion This study indicates that thrombogenicity might be affected immediately after M-TEER probably due to changes in flow conditions. In particular, platelet aggregation involving the ADP receptor pathway significantly correlated with postprocedural bleeding events. Whether these results could guide peri-interventional antithrombotic therapy and improve peri- and postprocedural outcome requires further investigation.
The market timing ability of bond mutual funds
Authors: Yin Zhengnan , O’Sullivan Niall , Sherman Meadhbh 
Published: September 2024

AbstractWe apply the nonparametric methodology of Jiang (Journal of Empirical Finance 10:399–425, 2003) to examine whether bond mutual funds can time the bond market by adjusting their portfolios' market exposure based on anticipated market movement. This approach offers several advantages over the widely used regression-based tests such as Treynor and Mazuy (Harvard Business Review 44(4):131–136, 1966) and Henriksson and Merton (The Journal of Business 54(4):513–533, 1981). In a comprehensive study covering the USA, UK, and China, we find some evidence of positive market timing of bond funds at the individual fund level. On average, bond funds show neutral to slightly negative market timing abilities. After controlling for public information, we find that a smaller number of bond funds successfully time the market based on private timing signals. In terms of categories, we find strong evidence of positive market timing for Government bond funds as a group, consistent with the findings of Huang and Wang (Management Science 60:2091–2109, 2014).
Industrial policy, green challenges, and international business
Authors: Benito Gabriel R. G. , Meyer Klaus E. 
Published: September 2024

AbstractNation-states are designing their industrial policies increasingly to not only enhance national competitiveness, but also to simultaneously address “Green Challenges”, concerns about the natural environment that require concerted action among different actors in society, including domestic and foreign multinational enterprises (MNEs). This blending of global and national policy objectives is leading to a new wave of industrial policies in advanced economies that are informed by scholarly discourses in evolutionary economics, innovation systems, and 'wicked problems'. We discuss the implications of these sustainability-oriented industrial policies for MNEs. They operate in increasingly diverse local ecosystems shaped by local actors and local policies as we illustrate for two such ecosystems in Nordic countries: circular economy and energy transition. Many MNEs face a tension between capabilities they could use to help nations achieve their sustainability goals and incentives to protect existing rents and business models. They may thus engage pro-actively or reactively in both market and nonmarket realms in each country in which they operate. We discuss the interactions between MNEs, governments, and other actors in host countries pursuing both sustainability and competitiveness objectives, and outline how ensuing tensions create new challenges and opportunities for international business scholarship.
Foreign-origin managers and FDI location choice
Authors: Coda Zabetta Massimiliano , Miguelez Ernest , Lissoni Francesco , Hegarty Sarah 
Published: September 2024

Abstract
Building upon the upper echelons theory of organizations as applied to internationalization strategies, we investigate the impact of foreign-origin top management team (TMT) members on their companies’ location choice. We propose that a manager-from-target effect may exist, by which a manager’s knowledge of their country of origin increases the likelihood of choosing that country as a target. We expect it to be stronger for acquisitions than for greenfield investments, the inputs of foreign-origin managers being more relevant in the first case. Based on a large sample of foreign direct investment from 2013 to 2019, and using name analysis to identify TMT members’ origins, we find that the effect is present in both establishment modes but larger and more robust for acquisitions. It is also larger in companies with less diverse TMTs, for which targeting one manager’s country of origin instead of others’ may be less likely to cause conflict. Future research should explore whether investments in locations suggested by managers from the target country outperform others. If this is the case, it implies that recruiting foreign-origin top managers can improve a company’s internationalization strategy via better location choices.
“Th’oppressor’s wrong,” or, what’s Hamlet to the Borderlands?
Authors: Santos Kathryn Vomero 
Published: September 2024

AbstractThis article offers a critical analysis of two poetic appropriations of Hamlet’s “To be or not to be” soliloquy: “El Hamlet Fronterizo” by Guillermo Gómez-Peña and “To be a Pocha or not to be” by Iris De Anda. Both poets use the languages, geographies, and ontological concerns of the US–Mexico Borderlands to reimagine the Danish prince’s famously introspective speech as a performance text that reflects their lived experiences and consciousnesses as border subjects. For Gómez-Peña and De Anda, the figure of Hamlet becomes a means through which to reject Western colonial worldviews, to refuse assimilation, and to center Borderlands ways of knowing, being, and doing. When Hamlet’s soliloquy is reimagined in these ways, the most urgent question is not whether or not to be but rather what it means to be someone whose existence is made vulnerable precisely because it exceeds the increasingly policed boundaries of nation, language, race, and gender.

This paper presents the results of spectroscopic measurements of plasma in a linear simulator of a plasma-beam installation (PBI) for conducting materials science research. For the first time, non-contact optical diagnostic methods were employed to measure the plasma parameters in the PBI. These measurements were allowed for the clarification of the PBI plasma parameters and the identification of transition zones in different operational modes. Analysis of the plasma emission spectrum enabled the identification of impurity spectral lines and the estimation of key plasma parameters under varying experimental conditions. The spectra were recorded using two optical spectrometers covering a wavelength range of 200–800 nm. The experimental conditions varied in terms of electron beam accelerating voltage (1–5 kV), working gas pressure (1–6 mTorr), and target bias voltage (from −500 to −100 V). The Boltzmann plot method and Stark broadening of the Balmer lines were used to estimate electron temperature and density. Based on the obtained spectroscopic data, the electron density and the electron temperature were determined. The methods described in this study are applicable to linear plasma devices.
Study of quantum nonlocality by CHSH function and its extension in disordered fermions
Authors: Kuno Yoshihito 
Published: September 2024

Abstract
Quantum nonlocality is an important concept in quantum physics. In this work, we study the quantum nonlocality in a fermion many-body system under quasi-periodic disorders. The Clauser–Horne–Shimony–Holt (CHSH) inequality is systematically investigated, which quantifies quantum nonlocality between two sites. We find particular behaviors of the quantifiers of quantum nonlocality around the extended and critical phase transitions in the system and further that the CHSH inequality is not broken in the globally averaged picture of the maximum value of the quantum nonlocality, but the violation probability of the CHSH inequality for two site pairs in the system becomes sufficiently finite in the critical phase and on a critical phase boundary. Further, we investigate an extension of the CHSH inequality, Mermin–Klyshko–Svetlichny (MKS) polynomials, which can characterize multipartite quantum nonlocality. We also find a similar behavior to the case of CHSH inequality. In particular, in the critical regime and on a transition point, the adjacent three-qubit MKS polynomial in a portion of the system exhibits a quantum nonlocal violation regime with a finite probability in the critical phase.
