Authors: He Bishi , Chen Yuanjiao , Zhu Darong , Xu Zhe 
Published: July 2023

Abstract
Deep learning technology can effectively assist physicians in diagnosing chest radiographs. Conventional domain adaptation methods suffer from inaccurate lesion region localization, large errors in feature extraction, and a large number of model parameters. To address these problems, we proposes a novel domain adaptation method called WDDM, which joints Wasserstein distance and discrepancy metric for chest radiograph abnormality identification. Specifically, our method uses BiFormer as a multi-scale feature extractor to extract deep feature representations of data samples, which focuses more on discriminant features than convolutional neural networks and Swin Transformer. In addition, based on the loss minimization of Wasserstein distance and contrast domain differences, the source domain samples closest to the target domain are selected to achieve similarity and dissimilarity across domains. Experimental results show that our method improves the mean value of AUC of chest radiograph classification by no less than 14.8% against the unmigrated methods which classify the target domain by training the resulting network directly with the source domain. In short, our method achieves higher classification accuracy and better generalization performance.
Structurally unstable quadratic vector fields of codimension two: families possessing one finite saddle-node and a separatrix connection
Authors: Artés Joan C. 
Published: July 2023

Abstract
This paper is part of a series of works whose ultimate goal is the complete classification of phase portraits of quadratic differential systems in the plane modulo limit cycles. It is estimated that the total number may be around 2000, so the work to find them all must be split in different papers in a systematic way so to assure the completeness of the study and also the non intersection among them. In this paper we classify the family of phase portraits possessing one finite saddle-node and a separatrix connection and determine that there are a minimum of 77 topologically different phase portraits plus at most 16 other phase portraits which we conjecture to be impossible. Along this paper we also deploy a mistake in the book [5] linked to a mistake in [38].

Perioperative risk factors of pressure injuries in Korean patients after surgery for intracranial hemorrhage: A retrospective cohort study
Authors: Choi On-You , Son Youn-Jung 
Published: July 2023

Abstract

Neurosurgical patients are more likely to develop pressure injuries caused by long operation time and decreased consciousness. However, there is a lack of knowledge on the perioperative risk factors of pressure injuries among neurosurgical patients in Korea. Thus, this study aimed to identify the incidence and perioperative risk factors of post-operative pressure injuries in patients after brain surgery. This retrospective cohort study was conducted in a tertiary care university hospital in Korea. Patients who underwent surgery for treating intracranial hemorrhage were included. Data from medical records for analysis were collected between April 2010 to March 2020. Among the 386 patients, 103 patients (26.7%) developed postoperative pressure injuries. The most common site of pressure injury was the coccyx (n = 56, 38.9%). About more than half of patients were in stage Ⅱ and the 43 (41.7%) patients developed pressure injuries after 14 days of post-surgery period. Multivariable logistic regression revealed that being older age (p = .025), receiving packed red blood cells transfusion during intensive care unit stay (p = .004), and staying in the intensive care unit for more than 7 days (p < .001) increased the risk of pressure injury after brain surgery. Older adults with longer stay in neurosurgical intensive care units and requiring blood transfusion should be carefully assessed to prevent pressure injuries within 7 days of intensive care unit admission. Postoperative pressure injuries of neurosurgical patients can be prevented by effective handover communication at intra-and inter-departmental level.
Beyond Color and Pattern: Elucidating the Factors Associated with Intraspecific Aggression in the Mimic Poison Frog (Ranitomeya imitator)
Authors: Bieri Eli , Rubio Andrew O. , Summers Kyle 
Published: July 2023

Abstract
Assortative or disassortative aggression – when individuals display more aggression towards conspecifics with similar or different phenotypic characteristics – can either maintain polymorphisms or facilitate gene flow between populations depending on which direction the aggression is aimed. Deciphering which factors elicit or prevent aggression is crucial to improving our knowledge of the origin and maintenance of reproductive barriers and subsequent speciation. The Peruvian mimic poison frog, Ranitomeya imitator, is a monogamous and territorial species that has evolved into four distinct color-pattern morphs in a mimetic radiation. Here we use historical landscape genetic data and competition trials between male individuals sourced from different populations and color-pattern morphs to show that the level of aggression between individuals is not associated with color morph or body size but rather with source population. Individuals spent more time in combat with individuals from their own deme (genetically homogeneous population), irrespective of color morph or size. These findings indicate that genotypic similarity is correlated with increased aggression in R. imitator, though the mechanism by which R. imitator males identify conspecifics as territorial threats remains unclear. As body size and color morph were not significantly associated with aggression levels, this study emphasizes the necessity of further research to identify whether other phenotypic traits are influencing territorial behavior between male frogs, and if these factors play a role in increasing gene flow, or conversely, the formation of reproductive barriers between populations.

Published: July 2023

Abstract
The use of unconventional natural fibres such as bast fibres from several plants is gaining importance as conventional natural fibres such as cotton, wool, silk are considered less sustainable fibres for several reasons such as the massive water and pesticide consumption for cultivation in case of cotton for instance. The need for sustainable fibres to partly replace these conventional fibres is gaining importance in the field of apparel and textiles. In this study, we have attempted to extract fibres from the stems of Calotropis gigantea using standing water and without any additives, for a period of 3 days. The FTIR spectroscopy of dry extracted calotropis fibres and water-retted fibres was performed. It is observed the effect of water retting is significant and there is a remarkable decrease in the lignin and pectin content. In addition, it is also noticed that the hemi-cellulose content in the fibre also decreased. This shows that water retting is also an efficient and sustainable method for fibre extraction from Calotropis gigantea.

Abstract
Clinician engagement in research has positive impacts for healthcare, but is often difficult for healthcare organisations to support in light of limited resources. This scoping review aimed to describe the literature on health service-administered strategies for increasing research engagement by medical practitioners. Medline, EMBASE and Web of Science databases were searched from 2000-2021 and two independent reviewers screened each record for inclusion. Inclusion criteria were that studies: sampled medically qualified clinicians; reported empirical data; investigated effectiveness of an intervention in improving research engagement; and addressed interventions implemented by an individual health service/hospital. Of the 11,084 unique records, 257 studies were included. Most (78.2%) studies were conducted in the United States, and were targeted at residents (63.0%). Outcomes were measured in a variety of ways, most commonly publication-related outcomes (77.4%), though many studies used more than one outcome measure (70.4%). Pre-post (38.8%) and post-only (28.7%) study designs were the most common, while those using a contemporaneous control group were uncommon (11.5%). The most commonly reported interventions included Resident Research Programs (RRPs), protected time, mentorship, and education programs. Many articles did not report key information needed for data extraction, (e.g. sample size). Despite a large volume of research, poor reporting, infrequent use of robust study designs and heterogenous outcome measures limit application of these studies and prospects for future systematic reviews/meta-analyses. The most compelling available evidence pointed to RRPs, protected time and mentorship as effective interventions. Further high-quality evidence is needed to guide healthcare organisations on increasing medical research engagement.

Published: July 2023

Abstract
Introduction:
The existing literature on the combination of acute pancreatitis (AP) and COVID-19 is scarce. The objective of our study is to compare the clinical outcomes and occurrence of long COVID syndrome in AP patients with and without COVID-19, while investigating the potential impact of COVID-19 on the severity, mortality rate, and long COVID syndrome in these patients.
Materials and methods
This retrospective, observational study was conducted at a single center. It included patients aged 18 years and above who were diagnosed with AP during the pandemic. Patients were categorized into two groups based on the results of RT-qPCR testing: the COVID-19 positive group and the COVID-19 negative group. The study aimed to compare the severity of AP, mortality rate, and occurrence of long COVID syndrome between these two groups.
Result
A retrospective review was conducted on 122 patients diagnosed with acute pancreatitis between December 1, 2022, and January 31, 2023. Out of these patients, 100 were included in the study. The analysis revealed no significant differences in mortality rate, severity, and sequelae between AP patients with COVID-19 and those without COVID-19 (p > 0.005). However, a statistically significant difference was observed in the occurrence of long COVID syndrome, specifically in the presence of cough (P = 0.04).
Conclusion
This study demonstrates that the presence of COVID-19 in patients with pancreatitis does not lead to an increase in the mortality and severity rate of pancreatitis.

Published: July 2023

Abstract
Introduction: The aim of this study is to evaluate the influence of using a single-file reciprocating system on the technical quality of root canal filling and treatment radiographically for cases treated by undergraduate students.
Materials and Methods: This is a retrospective cross-sectional clinical study for endodontically treated teeth by 4th-year undergraduate students during the academic year 2021-2022. Root canal preparation was performed using the WaveOne Gold system with a matching single-cone gutta percha. The collected data included gender, tooth position, number of canals, and timing of treatment (the first or second semester). The quality of the root canal filling was assessed based on root canal filling length, density, and taper. The presence of ledge, apical transportation, perforation, and separated instrument were recorded.
Results: The total number of teeth included in the study was 601. The length of the root canal filling was adequate in 93.51% of the teeth, underfilled in 2.82%, and overfilled in 3.66%. The density and taper were adequate in 96.5% and 98.16% of the teeth, respectively. There was no significant difference among the parameters of length, taper, density, and all procedural errors in relation to the arch type. However, there was a significant difference between anterior and premolar teeth in regards to taper, density, and overall quality of root canal filling. The overall quality of root canal treatment was acceptable in 527 teeth (87.68%), with no significant difference between the teeth (P = 0.256).
Conclusion: The quality of root canal treatment performed by undergraduate students has improved with the use of a single-file reciprocating system for preparation.

Published: July 2023

Abstract
The adequate application of Building Information modeling (BIM) in sustainable building design known as green BIM, ensures the exchange of accurate information to reduce the buildings' carbon emissions and enhance the overall sustainability performance. However, a major challenge in sustainable building design is the persistent exchange of inaccurate data, resulting in flawed decisions. This study develops a Green BIM Process Model to explicitly guide the multidiscipline team to use the diverse BIM software to efficiently exchange cumbersome sustainability information. The process model focuses on building massing; fabric and layout optimization; and mechanical electrical & plumbing systems. After a critical literature review, the major components of efficient information exchange in the BIM-based sustainable building design process were established. Then, an in-depth interview was conducted with 26 construction professionals and analyzed using the narrative analysis technique. As a result, the best practices for the holistic coordination of the established major components were ascertained. Afterward, the Green BIM Process Model was developed by using Integrated DEFinition techniques to explicitly model the relationship between the established major components. The novel Green BIM Process Model provides a pragmatic approach that defines how the multidiscipline team can exchange accurate information and in turn, make viable decisions that can enhance the sustainability performance of buildings.

Abstract
B-cell acute lymphoblastic leukemia (ALL) is characterized by the highly heterogeneity of pathogenic genetic background, and there are still approximately 30-40% of patients without clear molecular markers. To identify the dysregulated genes in B-cell ALL, we screened 30 newly diagnosed B-cell ALL patients and 10 donors by gene expression profiling chip. We found that ECM1 transcript level was abnormally elevated in newly diagnosed B-cell ALL and further verified in another 267 cases compared with donors (median, 124.57% vs. 7.14%, P<0.001). ROC analysis showed that the area under the curve of ECM1transcript level at diagnosis was 0.89 (P <0.001). Patients with BCR::ABL1and IKZF1 deletion show highest expression level (210.78%) compared with KMT2A rearrangement (39.48%) and TCF3::PBX1 rearrangement ones (30.02%) (all P <0.05). Also, the expression level of ECM1 was highly correlated with the clinical course, as 20 consecutive follow-up cases indicated. The 5-year OS of patients (non-KMT2A and non-TCF3::PBX1rearrangement) with high ECM1 transcript level was significantly worse than the lower ones (18.7% vs. 72.9%, P <0.001) and high ECM1transcript level was an independent risk factor for OS (HR=5.77 [1.75-19.06], P=0.004). After considering transplantation, high ECM1 transcript level was not an independent risk factor, although OS was still poor (low vs.high, 71.1% vs. 56.8%, P =0.038). Our findings suggested that ECM1may be a potential molecular marker for diagnosis, minimal residual disease (MRD) monitoring, and prognosis prediction of B-cell ALL.

Published: July 2023

Abstract
Background
Parotid lesions show overlapping morphological findings and types of time/intensity curves. This research aimed to evaluate the role of two-phase multislice spiral computed tomography (MSCT) texture analysis in differentiating between benign and malignant parotid lesions.
Methods
In this retrospective research, MSCT was carried out on 90 patients. Each lesion was segmented on axial CT images by manually, and 33 texture features and morphologic CT features were assessed. Logistic regression analysis was used to identify predictors of malignancy (P < 0.05 was considered statistically significant), followed by receiver operating characteristic (ROC) analysis to determine diagnostic efficacy.
Results
Univariate logistic regression analysis demonstrated that morphological CT features (shape, size, and invasion of adjacent tissues) and 17 CT texture parameters were significant differences between benign and malignant lesions (P < 0.05). Multivariate binary logistic regression demonstrated that shape, invasion of adjacent tissues, entropy and inverse difference moment were independent factors for malignant tumours. The diagnostic accuracy of multivariate binary logistic models based on morphological parameters, CT texture features, and a combination of both was 87.8%, 90%, and 93.3%, respectively.
Conclusion
Two-phase MSCT texture analysis was conducive to differentiating between malignant and benign neoplasms in the salivary gland, especially when combined with morphological CT features.

Abstract
Introduction:
This study investigates the processes regarding changing malaria treatment policies in Vietnam. Moreover, it explores the feasibility of introducing triple artemisinin-based combination therapies (TACTs) in Vietnam to support the national malaria control and elimination plan.
Methods
Data were collected through desk review of policy documents in combination with 12 in-depth interviews with key stakeholders.
Results
TACTs are considered as a useful backup strategy in case future treatment failures with current artemisinin-based combination therapies (ACTs) would occur. Moreover, TACTs are also considered as a promising strategy to prevent the re-establishment of malaria. However, regulatory procedures and implementation timelines for TACTs were expected to be lengthy. Therefore, stakeholder engagement strategies should be initiated soon, stipulating the benefits of TACTs deployment. A simplified validation of registration or an import permit without registration that has been applied to the introduction of artesunate-pyronaridine was proposed to accelerate the introduction of TACTs. Global-level support through WHO recommendations and prequalification were considered critical for supporting the introduction of TACTs in Vietnam.
Conclusions
Appropriate approach strategies and early stakeholder engagement will be needed to accelerate the introduction of TACTs in Vietnam.
