Published: November 2024

OBJECTIVE:
To evaluate whether individuals who have a placenta previa or low-lying placenta that resolves before delivery are at increased risk of postpartum hemorrhage and postpartum hemorrhage–related morbidity.

METHODS:
This was a prospective, multicenter, 1:3 matched cohort study of pregnant individuals with singleton gestations diagnosed with low placentation by transvaginal scan at 19 to 23 weeks of gestation between January 2021 and December 2023 at nine academic maternity centers (exposed participants). Unexposed participants were those with a normally located placenta, matched in a 1:3 ratio according to parity. Resolution of low placentation was diagnosed when placenta was at 20 mm or more from the internal os. Individuals with fetal anomalies, hematologic disorders, therapeutic anticoagulation, placenta accreta spectrum disorder, vasa previa, persistent low placentation at birth, and delivery at a nonenrolling center were excluded. Primary outcome was postpartum hemorrhage of 1,000 mL or more. Secondary outcomes included postpartum hemorrhage of 1,500 mL or more, use of second-line uterotonic drugs, blood transfusions, additional procedures to control bleeding, intensive care unit admission, and hospital stay for more than 7 days. Multivariable logistic regression adjusted for confounders was used to estimate independent associations with outcomes.

RESULTS:
The study population included 182 exposed and 589 unexposed participants. Individuals with resolved low placentation had higher rates of smoking (P=.024), prior dilation and curettage (P=.012), posterior placenta (P<.001), and induction of labor (P=.038). Multivariate logistic regression analysis adjusted for confounders showed that exposed people had higher odds of postpartum hemorrhage of 1,000 mL or more (13.2% vs 4.1%, adjusted odds ratio [aOR] 3.1) compared with unexposed people and of use of second-line uterotonic drugs (28.0% vs 12.4%, aOR 2.69) and tranexamic acid (16.5% vs 7.5%, aOR 2.19), as well as hospital stay longer than 7 days (11.5% vs 3.4%, aOR 2.63).

CONCLUSION:
Individuals with resolved low placentation are at increased risk of postpartum hemorrhage and related complications compared with those who always had a normally located placenta.

Objective:
To investigate patency and clinical outcomes of alloplastic and other venous interposition graft materials in pancreatic surgery.

Background:
Vascular pancreatic surgery is increasingly performed for locally advanced pancreatic neoplasms. Different than other centers, we prefer to use alloplastic vascular graft materials for superior mesenteric vein and portal vein interposition in pancreatic surgery. Advantages are off-the-shelf availability at any customizable length, different diameters, and ring-enforcement but proposed concerns are their thrombogenicity and fatal complications.

Methods:
Patients who underwent elective pancreatic resections with mesoportal venous interposition grafts (ISGPS type 4) between 2003-2022 were identified from the institutional pancreatectomy registry. Alloplastic vascular grafts imply synthetic materials, either based on polytetrafluorethylene (PTFE) or polyethylene terephthalate (PET). Surgical details, clinicopathological, and follow-up data were analyzed. The patients were followed for graft patency by cross-sectional imaging.

Results:
In this study, 201 patients with venous interposition grafts were included (23% simultaneous arterial resections). Total pancreatectomy (41%) and pancreatoduodenectomy (35%) were the most frequent procedures. Vascular graft materials were alloplastic in 180 patients (83% PTFE and 17% PET) with a median diameter of 10 mm and a median length of 33 mm (measurement by CT scan). Patency rates among all graft materials at 7-, 30-, and 90-days were 99%, 93%, and 87%. Alloplastic grafts demonstrated superior patency over other materials (hazard ratio 2.7, P=0.009), and PTFE reached a 1-year patency of 78%. The all-cause 90-day mortality rate was 10%. No graft infection occurred.

Conclusion:
Alloplastic venous vascular grafts are safe and readily available tools in pancreatic surgery, especially for long-segmental mesoportal venous reconstructions.

Published: November 2024

BACKGROUND
Traumatic hemothoraces (HTXs) are common, and tube thoracostomy (TT) insertion is generally the initial management. However, a retained HTX can develop into a fibrothorax or empyema requiring secondary intervention. We hypothesized that irrigation of the thoracic cavity at the time of TT may prevent retained HTX.

METHODS
Pubmed, EMBASE, and Scopus were searched from inception to May 2024. Studies with adult trauma patients with traumatic HTX who received a TT and had patients who underwent thoracic irrigation were included. The primary outcome was failure rate, defined as retained HTX requiring a second intervention. Cumulative analysis was performed with χ2 for dichotomous variables and unpaired t test for continuous variables. A fixed-effects model was applied for meta-analysis.

RESULTS
Six studies were included in the analysis; two retrospective and four prospective observational studies. These studies included 1,319 patients (513 irrigated TT, 837 nonirrigated TT). The mean age of patients was 45 years, 81% were male, mean Injury Severity Score was 21, and 42% had penetrating trauma. Failure rate was significantly lower in the irrigation group on cumulative analysis (10.7% vs. 18.2%, p < 0.001) and meta-analysis (effect size, 0.704; 95% confidence interval, 0.218–1.190; I
2 = 0.4; p < 0.001]. In addition, on meta-analysis, the irrigation group had a shorter TT duration and hospital and ICU length of stay (all p < 0.05). There were no differences in overall infectious complications, readmission, or mortality; however, all the models favored the irrigation group.

CONCLUSION
Patients who undergo simultaneous TT and thoracic irrigation have a lower rate of retained HTX and require fewer secondary interventions. Thoracic irrigation for traumatic HTX should be considered; however, randomized studies are needed prior to development of guidelines.

Analysis of Intraoperative Visual Evoked Potentials for Inclusion of Unstable Electroretinograms
Authors: Cochard Eva , Bérard Nadia , Schaller Karl , Boëx Colette 
Published: November 2024

Purpose:
The objectives of the study were to evaluate the validity of intraoperative flash visual evoked potentials (VEPs) when electroretinograms (ERGs) were unstable, to compare white versus red light-emitting diodes, and to assess the impact of luminance on ERG variability.

Methods:
Thirty patients were included (Inomed system; pre- and postoperative visual fields). Possible changes in visual fields were assessed with mean defects in perimetry. The receiver operating characteristic (ROC) curves of normalized VEPs and of normalized and corrected VEPs with ERGs were compared.

Results:
Thirty-two eyes could be analyzed in 20 patients (mainly gliomas and meningiomas): 2 had a severe defect in their visual field, and 6 had a mild defect. The receiver operating characteristic curve indicated (1) normalized and corrected VEPs with ERGs were more reliable than normalized VEPs only (P < 0.03) and (2) an alarm threshold of 80% of normalized and corrected VEPs. No significant difference in variability of ERGs was found with white or red light-emitting diodes with this system. Increased luminance improved stability of ERGs (P < 0.05).

Conclusions:
Normalization and correction of VEPs with ERGs improved the validity of VEPs and indicated a 20% decrease as alarm criterion. This normalization and correction with peripheral excitation could be generalized to improve the reliability of neuromonitoring.

AbstractCD8+T cells play a central role in the cancer response to immune checkpoint blockade (ICB) treatment, with activity predicated upon antigen recognition by the associated T cell receptor (TCR) repertoire. The contribution of genetic variation to this in cancer treatment is under-explored. We have conducted a genome-wide and human leukocyte antigen (HLA)-focused analysis of CD8+T cell TCR repertoire to identify genetic determinants of variable gene (V-gene) and CDR3 K-mer usage from samples taken prior to and after ICB treatment (n=250). We find 11 genome-wide significantcisassociations and 10transassociations, primarily to the HLA, with V-gene usage meeting permuted P-value thresholds. Notably, TCR clones containing V-genes associated with HLA were less likely to be persistent across treatment. In a single-cell experiment, we find cells with HLA-matched TCR clones have increased tumor reactivity expression profiles and patients with HLA-matched TCR clones have improved overall survival. Our work indicates a complex relationship between genotype and TCR repertoire in the context of treatment with ICB, which has novel implications for understanding determinants of treatment response and patient outcomes.One Sentence SummaryTCR repertoire is strongly associated with specific HLA alleles in cancer patients, but immune checkpoint blockade influences this association.
Momentum shift and on-shell recursion relation for electroweak theory
Authors: Ema Yohei , Gao Ting , Ke Wenqi , Liu Zhen , Lyu Kun-Feng , Mahbub Ishmam 
Published: November 2024

We study the all-line transverse (ALT) shift which we developed for on-shell recursion of amplitudes for particles of any mass. We discuss the validity of the shift for general theories of spin ≤1, and illustrate the connection between Ward identity and constructibility for massive spin-1 amplitude under the ALT shift. We apply the shift to the electroweak theory, and various four-point scattering amplitudes among electroweak gauge bosons and fermions are constructed. We show explicitly that the four-point gauge boson contact terms in massive electroweak theory automatically arise after recursive construction, independent of UV completion, and they automatically cancel the terms growing as (energy)4 at high energy. We explore UV completion of the electroweak theory that cancels the remaining (energy)2 terms and impose unitarity requirements to constrain additional couplings. The ALT shift framework allows consistent treatment in dealing with contact term ambiguities for renormalizable massive and massless theories, which we show can be useful in studying real-world amplitudes with massive spinors.

Molten sulphate vanadateinduced hot corrosion behaviour of YSZ-reinforced thermal spray coatings at elevated temperature
Authors: Singh Sukhjiinder , Goyal Khushdeep , Bhatia Rakesh 
Published: November 2024

Purpose
The main cause of boiler tube failure in high-temperature thermal power plants is molten sulphate-vanadate-induced hot corrosion. Applying thermal spray coatings on alloy steels can reduce hot corrosion. This study aims to examine the impact of nano yttria stabilized zirconia (YSZ) reinforcement on Ni-20Cr composite coatings on hot corrosion behaviour of T22 steel in a corrosive environment of Na2SO4-60%V2O5 at 650 °C over 50 cycles.

Design/methodology/approach
The coatings were deposited using a high velocity oxyfuel technique. The samples were subjected to hot corrosion in a Silicon tube furnace at 650 °C for 50 cycles. Weight gain data after each cycle were used to analyse the kinetics of corrosion behaviour. Corrosion products were examined using X-ray diffraction, scanning electron microscopy, energy dispersive and cross-sectional analytical methods.

Findings
During investigation, nano YSZ-reinforced Ni-20Cr composite coatings on T22 steel were discovered to give superior corrosion resistance in a molten salt environment at 650 °C. Throughout the experiment, the coatings gained less weight and formed protective oxide scales. Increased YSZ concentration in the coating matrix resulted in better protection against hot corrosion.

Research limitations/implications
The inclusion of nano YSZ reduced porosity in Ni-20Cr coatings by filling voids and interlocking particles, as well as blocking the penetration of corroding species, hence improving the corrosion resistance of composite coatings. The corrosion rate decreased with increasing YSZ content in the coating matrix.

Originality/value
It should be noted that the high temperature corrosion behaviour of thermally sprayed nano YSZ-Ni-20Cr composite coatings has never been investigated and is not documented in the literature. As a result, the current study can provide useful information for the application of nano YSZ-reinforced coatings in high-temperature fuel combustion conditions.
Trends and patterns in behavioral accounting research: 53 years of bibliometric analysis
Authors: Chauhan Abhay Singh , Sikarwar Tarika Singh , Raj Manisha 
Published: November 2024

Purpose
The purpose of this study is to explore the quality of research work done in behavioral accounting through bibliometric analysis so that biases can be spotted and implications can be drawn.

Design/methodology/approach
The most recent papers on a given topic – behavioral accounting in this study – are gathered, assessed and analyzed using a systematic literature review approach, which is a rigorous process. Books, scientific publications and conference papers were used to discover, compile and synthesize pertinent information (Garca, 2013; Snyder, 2019). In this study, the authors used an iterative cycle methodology, which entails selecting pertinent keywords, conducting a literature search in the database of choice and then conducting the analysis.

Findings
Using bibliometric analysis, this study offers a fresh viewpoint on fundamental behavioral accounting concepts. The results suggest that important areas in the relevant behavioral accounting disciplines are changing, with important ramifications for academics and practitioners to better understand prospect theory and social identity theory.

Research limitations/implications
Researchers should parameterize their outputs to make it easier to synthesize the state of the art in behavioral accounting, which would advance the subject.

Practical implications
The study has important policy implications because it shows that decision-makers are increasingly focused on creating ethical and open accounting practices, which are essential for building improved accounting practices in the Big Data era.

Social implications
It is elementary in and of itself to recognize that accounting data are an outcome and a consequence of human behavior. The study itself makes a case for the social ramifications of this kind of study.

Originality/value
The study offers a comprehensive bibliometric analysis of behavioral accounting research sourced from the Scopus database. It presents a curated collection of leading works in the domain, categorized by articles, authors, publications, institutions and nations. This examination provides a current snapshot of advancements in behavioral accounting and can be perceived as an evolution of previous literature reviews that relied on traditional approaches. Notably, this is the inaugural study using solely bibliometric techniques.
Assessing the market performance of US corporate spin-offs: effects of directors’ age and external board appointments along with their interaction
Authors: Ozbek O. Volkan 
Published: November 2024

Purpose
Spin-offs, as “popular” corporate restructuring mechanisms in the USA, aim to boost the shareholder value after the separation of a subsidiary/division from its divesting (parent) company. The role of the board, as a “vital” governing mechanism, in the success of these spun-off subsidiaries (child firms) is very critical because directors must ensure that they can provide these recently independent entities with their in-depth expertise, knowledge, industry experience, corporate connections and other resources so that adapting to their “new” market conditions will not be problematic. The purpose of this study is to examine whether two board demographic characteristics (namely, board members’ age and external directorships) along with their interaction affect the child firm’s market valuation, which extends previous work on the board of directors and corporate spin-offs. The theoretical arguments are grounded in resource dependence and upper echelons theories.

Design/methodology/approach
The sample included 136 completed spin-offs between 2000 and 2014. The data on board characteristics were collected by using companies’ proxy statements available on the securities and exchange commission website whereas firm and industry characteristics were collected by using the Compustat database.

Findings
The author has found that considered independently, board members’ average age and external directorships show positive and significant relationships with the change in market valuation of the child firm; however, the interaction effect of both variables appears to lessen this effect but remains significant.

Originality/value
The authors have shown that while the main effects of both board-level variables have positive and significant effects on the market performance of spun-off subsidiaries (as hypothesized), their interaction will make this effect go in the opposite direction.
Towards crafting a cure for employee turnover: a social exchange theory perspective
Authors: Priyanka  , Khera Shikha N. , Suri Pradeep Kumar 
Published: November 2024

Purpose
This study aims to attempt to put forward a nuanced conceptual framework to develop a better understanding of the relationship between job crafting and employees’ turnover intention, by bringing in “social exchange theory” perspective and proposing the mediating role of perceived organizational support (POS).

Design/methodology/approach
An extant review of literature was undertaken to identify and summarize the relevant findings on the topics of job crafting, POS and turnover intention, which further led to the development of hypotheses and the conceptual framework.

Findings
Results indicate that job crafting has a significant relationship with turnover intention with POS as an underpinning variable.

Practical implications
This study generates actionable insights and suggestions for the business leaders and practitioners, which can help them in handling the problem of rising employee turnover in today’s era marked by evolving attitudes and mindsets of the employees, along with the catalytic effects of pandemic and “Great Resignation”. Insights generated in this study for reducing dysfunctional employee turnover would have a stabilizing effect and lead society and business towards sustainable growth.

Social implications
Insights generated in this study for reducing dysfunctional employee turnover would have a stabilizing effect and lead society and business towards sustainable growth.

Originality/value
This study is original in three ways. Firstly, the study introduces a unique perspective by putting forward a conceptual framework nestled in the social exchange theory. Secondly, to the best of the authors’ knowledge, it is the first study to examine the role of POS as a mediator in the association between job crafting and turnover intention. Thirdly, by proposing POS as an outcome of job crafting, this study suggests a reciprocal relationship between job crafting and POS.
Interdisciplinary participation in climate-adapted urban land-use planning – findings of two gaming simulations in the city of Bottrop, Germany
Authors: Fuchs Marisa , Kirstein Madeleine Loren 
Published: November 2024

Purpose
Sustainable and climate-adapted urban development requires integrative governance approaches and forms of collaboration between different disciplinary actors in urban society. Integrative approaches are a particular challenge for those planning cultures in which they are not yet sufficiently established. This also applies to formal urban land-use planning in Germany, which forms the governance setting of this study. This study aims to examine how interdisciplinary participation in formal urban land-use planning contributes to the consideration of climate adaptation in the planning process.

Design/methodology/approach
This paper traces the process of two differently designed interdisciplinary participation formats based on the methodological framework of a gaming simulation, each in the context of a formal urban land-use planning procedure in Bottrop, Germany. The gaming simulations are designed as performance simulations in which we involved several representatives from different public authorities.

Findings
The gaming simulations show that interdisciplinary participation can lead to an increased awareness of climate adaptation requirements in particular and a mutual understanding of different logics of action in the context of comprehensive and sustainable urban planning in general. In addition, this paper provides recommendations as to how and under what conditions the benefits of the simulations can be transferred to municipal practice.

Originality/value
While integrative and interdisciplinary formats are increasingly being used in the context of informal urban planning, this does not apply to formal urban land-use planning. Participation in formal urban land-use planning procedures is classically linear and multidisciplinary in Germany. Using two simulated interdisciplinary participation formats, this paper tested to what extent the consideration of climate adaptation requirements as a cross-sectoral task can benefit from interdisciplinarity in the context of two formal urban land-use planning procedures.
