Dynamic connectedness and hedging opportunities of the commodity and stock markets in China: evidence from the TVP-VAR and cDCC-FIAPARCH
Authors: Li Binlin , Haneklaus Nils , Rahman Mohammad Mafizur 
Published: March 2024

AbstractThis study examines the dynamic connectedness and hedging opportunities between CSI300 (China Security Index 300) and copper, gold, PTA (purified terephthalic acid), and soybean in China from January 09, 2008, to June 30, 2023. A TVP-VAR and cDCC-FIAPARCH modeling framework was used for the empirical investigation. The results show that the total connectedness index can effectively capture cross-asset information transmission in China’s financial markets. Copper returns are the dominant volatility transmitters, while CSI300, gold, and soybean returns are net recipients. The Russian–Ukraine war reinforced the safe-haven role of gold. Finally, investors with CSI300 long positions may benefit from prioritizing gold for hedging, while those with CSI300 short positions profit more from allocating gold to PTA. Portfolio managers and investors can use the findings to track the dynamics of systemic risk and adjust their long/short positions when investing in China's stock and commodity markets.

Abstract
Purpose
To assess the relationship between macular choroidal thickness (CT) measurements and retinal sensitivity (RS) in eyes with myopia and different stages of myopic maculopathy.

Methods
A masked, cross-sectional, and consecutive study involving patients with emmetropia/myopia (control group) and high myopia (HM) eyes. Automated choroidal thickness (CT) and manual outer retinal layer (ORL) thickness were acquired using swept-source optical coherence tomography, while retinal sensitivity (RS) assessed by microperimetry (MP3) in all regions of the macular Early Treatment Diabetic Retinopathy Study (ETDRS) grid. Comparisons were made between groups, and correlations were performed among these measurements, demographic and ocular parameters and myopic maculopathy classification.

Results
A total of 37 (74 eyes) patients were included in the study. The mean age was 39 ± 13 years, and 28 patients (76%) were female. HM eyes exhibited inferior best-corrected visual acuity and a more advanced myopic maculopathy classification compared to the control group. The mean macular CT were 255 and 179 μm in the control and HM eyes (P < 0.001), respectively. In the HM eyes, superior ETDRS region presented the greatest values. Mean RS in control and HM groups was 28 and 24 dB (P = 0.001), respectively. Inner temporal followed by superior, were the regions of higher RS. Mean ORL thickness was 83 and 79 μm (P < 0.001), in the control and HM groups, respectively. The inner temporal ETDRS region presented the thickest measure. CT correlated significantly with RS (r = 0.41, P < 0.001) and ORL thickness, (r = 0.58, P < 0.001), which also correlated with RS (r = 0.40, P < 0.001). Spherical equivalent, axial length and myopic maculopathy stage were the parameters that most correlated with CT, RS and ORL thickness. For every 100 μm increase in thickening of CT there was an average increase of 3.4 μm in ORL thickness and 2.7 dB in RS. Myopic maculopathy classification demonstrated influence only with CT.

Conclusion
Myopia degree is related to ORL and choroidal thinning and deterioration of retinal sensitivity in some ETDRS regions of the macula. Choroidal thinning is associated to with a decline of retinal sensitivity, thinning of ORL, and worsening of myopic maculopathy classification, so new treatments are necessary to prevent myopia progression.

Published: March 2024

Abstract
Background
Toxoplasmosis is considered one of the most common public health troubles. Among these health troubles, toxoplasmosis was recently linked to many neuropsychiatric and behavioral disorders, especially autism spectrum disorder (ASD). The purpose of this study was to determine the seroprevalence of toxoplasmosis in children with ASD.

Methods
The study was conducted on 100 children, grouped in two groups; group 1 (patient group) included 50 children with ASD and group 2 (control group) included 50 healthy children. ASD in the patient group was diagnosed according to DSM 5 criteria of ASD. Every child involved in this study underwent a history taking, a clinical examination, and laboratory investigations to detect serum anti-Toxoplasma IgG and IgM antibodies using ELISA. Children of the patient group were further assessed using the Childhood Autism Rating Scale to evaluate the severity of their symptoms.

Results
The seroprevalence of IgG among ASD children was highly significant compared to the healthy children. The detected difference between the 2 groups regarding seroprevalence of anti-Toxoplasma IgM antibodies was insignificant. No significant correlation could be demonstrated between Toxoplasma infection and severity of autistic symptoms in the ASD group. Furthermore, the study revealed an increase in anti-Toxoplasma IgG antibodies in ASD children with positive family history of ASD rather than those with no such history. In addition, an increase in seroprevalence of both anti-Toxoplasma antibodies among children with low socioeconomic standards compared to children with moderate or high standards.

Conclusions
The study revealed that the old but not the recent infection with Toxoplasma in children could be linked to their ASD.

PURPOSE To evaluate the effectiveness of endoscopic screening against incidence of and mortality from esophageal squamous cell carcinoma (ESCC). METHODS From January 2012 to September 2016, we conducted a community-based cluster randomized controlled trial involving permanent residents age 45-69 years in a high-risk region for ESCC in northern China. A total of 668 targeted villages were randomly assigned in a 1:1 ratio to the screening group (offered Lugol's chromoendoscopy) or control group (no screening). Intention-to-treat and per-protocol analyses were performed to compare esophageal cancer (EC) incidence and mortality between the two groups. The per-protocol analysis adjusted for nonadherence to the screening procedure. RESULTS A total of 33,847 participants were included in the analysis: 17,104 in the screening group, 15,165 (88.7%) of whom underwent screening, and 16,743 in the control group. During a maximum follow-up of 9 years, EC incidence in the screening and control groups were 60.9 and 72.5 per 100,000 person-years, respectively; mortality in the screening and control groups were 29.7 and 32.4 per 100,000 person-years, respectively. Compared with the control group, the incidence and mortality of the screening group reduced by 19% (adjusted hazard ratio [aHR], 0.81 [95% CI, 0.60 to 1.09]) and 18% (aHR, 0.82 [95% CI, 0.53 to 1.26]), respectively, in the intention-to-treat analysis; and by 22% (aHR, 0.78 [95% CI, 0.56 to 1.10]) and 21% (aHR, 0.79 [95% CI, 0.49 to 1.30]), respectively, in the per-protocol analysis. CONCLUSION With a 9-year follow-up, our trial suggests that chromoendoscopic screening induces modest reductions in EC incidence and mortality. A more efficient strategy for EC screening and subsequent patient management should be established to guarantee the effectiveness of endoscopic screening.

PURPOSE
Implementation of patient-reported outcomes (PROs) collection is an important priority in cancer care. We examined perceived barriers toward implementing PRO collection between centers with and without PRO infrastructure and administrators and nonadministrators.

PATIENTS AND METHODS
We performed a multinational survey of oncology practitioners on their perceived barriers to PRO implementations. Multivariable regression models evaluated for differences in perceived barriers to PRO implementation between groups, adjusted for demographic and institutional variables.

RESULTS

Among 358 oncology practitioners representing six geographic regions, 31% worked at centers that did not have PRO infrastructure and 26% self-reported as administrators. Administrators were more likely to perceive concerns with liability issues (aOR, 2.00 [95% CI, 1.12 to 3.57];
P
= .02) while having nonsignificant trend toward less likely perceiving concerns with disruption of workflow (aOR, 0.58 [95% CI, 0.32 to 1.03];
P
= .06) and nonadherence of PRO reporting (aOR, 0.53 [95% CI, 0.26 to 1.08];
P
= .08) as barriers. Respondents from centers without PRO infrastructure were more likely to perceive that not having access to a local PRO expert (aOR, 6.59 [95% CI, 3.81 to 11.42];
P
< .001), being unsure how to apply PROs in clinical decisions (aOR, 4.20 [95% CI, 2.32 to 7.63];
P
< .001), and being unsure about selecting PRO measures (aOR, 3.36 [95% CI, 2.00 to 5.66];
P
< .001) as barriers. Heat map analyses identified the largest differences between participants from centers with and without PRO infrastructure in agreed-upon barriers were (1) not having a local PRO expert, (2) being unsure about selecting PRO measures, and (3) not recognizing the role of PROs at the institutional level.

CONCLUSION
Perceived barriers toward PRO implementation differ between administrators and nonadministrators and practitioners at centers with and without PRO infrastructure. PRO implementation teams should consider as part of a comprehensive strategy including frontline clinicians and administrators and members with PRO experience within teams.
Buddhism, Heaven, and the Yellow Springs
Authors: Yi Zhao 
Published: March 2024

Abstract
Funerary jars called hunping were only produced within a short time frame (250s–320s ce) and in one specific region (southeastern China). Their function, the reason for their emergence, and the nature of their Buddha-like images have been controversial. By analyzing the basic structure and pictorial programs on hunping, this essay argues that they embody a binary structure comprising “heaven atop the axis mundi of Mount Kunlun” and the “underworld at the Yellow Springs.” In the third century, beliefs about “binary souls” changed. People in the south started to believe that the spiritual soul of the deceased (hun), traditionally worshipped at a family shrine, could instead be buried in a tomb. Moreover, they also worried about the haunting by the ghosts turned from the bodily souls whose corpuses decomposed too fast. This essay considers hunping as vessels to send binary souls each to their own place, heaven or the underworld. To better preach Buddhism with the approach of “match meaning” (geyi), early clerics adapted the cosmological theme of heaven and axis mundi by associating Mount Kunlun with Mount Sumeru and the Chinese heaven with Trāyastrimsa. They peopled Mount Sumeru with Buddhist arhats to replace the immortals on Mount Kunlun. Most of the Buddha-like images that appear on hunping depict those arhats.
The incubation environment does not explain significant variation in heart rate plasticity among avian embryos
Authors: Cones Alexandra G. , Schneider Eve R. , Westneat David F. 
Published: March 2024

ABSTRACT
The conditions an organism experiences during development can modify how they plastically respond to short-term changes in their environment later in life. This can be adaptive because the optimal average trait value and the optimal plastic change in trait value in response to the environment may differ across different environments. For example, early developmental temperatures can adaptively modify how reptiles, fish and invertebrates metabolically respond to temperature. However, whether individuals within populations respond differently (a prerequisite to adaptive evolution), and whether this occurs in birds, which are only ectothermic for part of their life cycle, is not known. We experimentally tested these possibilities by artificially incubating the embryos of Pekin ducks (Anas platyrhynchos domesticus) at constant or variable temperatures. We measured their consequent heart rate reaction norms to short-term changes in egg temperature and tracked their growth. Contrary to expectations, the early thermal environment did not modify heart rate reaction norms, but regardless, these reaction norms differed among individuals. Embryos with higher average heart rates were smaller upon hatching, but heart rate reaction norms did not predict subsequent growth. Our data also suggests that the thermal environment may affect both the variance in heart rate reaction norms and their covariance with growth. Thus, individual avian embryos can vary in their plasticity to temperature, and in contrast to fully ectothermic taxa, the early thermal environment does not explain this variance. Because among-individual variation is one precondition to adaptive evolution, the factors that do contribute to such variability may be important.

Published: March 2024

Abstract
Objectives
We aimed to evaluate the risk factors for the conversion from laparoscopic partial nephrectomy (LPN) to open surgery to achieve partial nephrectomy (PN).

Methods
Data from patients who underwent LPN between June 2020 and September 2023 were analyzed retrospectively. Patients in whom the PN procedure could be completed laparoscopically were recorded as the ‘Fully Laparoscopic’ (FL) group (n = 97), and those converted to open surgery from laparoscopy were recorded as the ‘Conversion to Open’ (CTO) group (n = 10). The demographic and pathologic variables were compared between groups. Regression analyses were used to define predictor factors, and receiver operating characteristic analysis was used to define the cut-off value of the surgical bleeding volume.

Results
Conversion to open surgery was found in 10/107 patients (9.3%). There was no statistical difference between groups in demographic and pathologic variables. Intraoperative blood loss volume, upper pole localized tumor, and posterior localized tumor were found to be statistically higher in the CTO group (p = 0.001, p = 0.001, and p = 0.043, respectively). Furthermore, these factors were only found to be statistically significant predictors of conversion to open surgery in both univariate and multivariate regression analyses. 235 cc was found to be the cut-off value of intraoperative blood loss volume for predicting conversion to open surgery (p = 0.001).

Conclusion
Using these predictive factors in clinical practice, treatment planning will lead to the possibility of starting the treatment directly with open surgery instead of minimally invasive options, and it may also provide a chance of being prepared for the possibility of conversion to open surgery peroperatively.

Published: March 2024

ZusammenfassungProzessmanagement ist sowohl in der Wissenschaft als auch in der Praxis weit verbreitet. Wir möchten persönliche Einblicke in beide Bereiche teilen, um die weitere Entwicklung und Anwendung von Prozessmanagementkonzepten zu fördern. Wir setzen uns für einen intensiveren Dialog zwischen Wissenschaft und Industrie ein. Aus praktischer Sicht müssen kritische Aspekte wie die organisatorische und sicherheitstechnische Perspektive intensiver erforscht und umgesetzt werden. Praktikable, umsetzbare akademische Prototypen sind entscheidend, um diese Lücken zu schließen. Vielversprechende Konzepte aus der Wissenschaft, wie die Modellierung von Organisationen und sicherheitstechnische Perspektiven, finden oft keine effektive Umsetzung in praktische Prozessmanagementprodukte, wie durch relevante Projekte nachgewiesen wird.

Published: March 2024

BackgroundThe COVID-19 pandemic caused several higher educational institutions to switch from traditional face-to-face to virtual learning medium. This abrupt shift came with new expectations, experiences and challenges to nursing/ midwifery students, particularly new users, and even more so when preparation, orientation, and support were lacking or ineffective. The present study therefore aimed at exploring the expectations, experiences and challenges of nursing students using the virtual learning medium during the COVID-19 pandemic.MethodsThis was a descriptive phenomenological design using 12 purposively sampled nursing and midwifery students from a public university in Ghana. With the aid of a semi-structured guide, individual face-to-face interviews were audiotaped, transcribed verbatim at a later time and deductively analyzed into themes using the customer experience execution model.ResultsParticipants were aged 22–36 years and involved equal number of males and females (n = 6), with majority being Christians (n = 11). Six themes were generated from the study: (1) “Initial thoughts and emotions” described participants initial reactions to the virtual educational medium during the pandemic; (2) "Expectations with the virtual medium" referred to the participants’ anticipations regarding the convenience offered by the virtual medium; (3) "Experiences with the virtual medium" depicted the participants’ recognition of both positive and negative encounters while using the virtual learning platform; (4) “Evaluation and recommendation” described participants’ reports of meeting expectations and recommendations they made to enhance virtual learning; (5) "Challenges and limitations of the virtual medium" typically represented the obstacles encountered by nursing/ midwifery students when they embraced the virtual medium; (6) “Prospects of the virtual medium” referred to participants’ views on the future of the virtual medium.ConclusionThe study has brought to light that the virtual education environment comes with its own expectations, experiences and challenges to students. Provision of adequate support such as orientation and simulation laboratories by higher education institutions to satisfy students’ needs is necessary to enhance nursing education.
Autoimmune Hepatitis on a Living Liver Donor: An Unexpected Long-Term Complication
Authors: Canhão Bernardo , Cipriano Augusta , Carvalho Armando , Simão Adélia , Madaleno João 
Published: March 2024

ABSTRACT
In Western countries, deceased donor liver transplantation remains the standard of care for patients with end-stage liver disease. Living donor liver transplantation is a viable and feasible strategy for patients with end-stage liver disease designed to mitigate the deceased organ shortage. Donor safety is the primary concern because liver donors, ideally, should not have any complication. We report a case of middle-aged woman without a history of chronic liver disease who developed autoimmune hepatitis more than 20 years after live liver donation. Changes in these patients' liver enzymes should prompt swift referral to an hepatologist for initial liver disease work-up.
Multiloculated Liver Abscess: A Complication of Endoscopic Ultrasound-Guided Liver Biopsy
Authors: Andrade Tia D. , Awadalla Mohanad , Mahmood Sultan , Berzin Tyler M. 
Published: March 2024

ABSTRACT
Endoscopic ultrasound (EUS)-guided liver biopsy is gaining popularity for liver parenchymal sampling due to its detailed visualization of liver anatomy, precision in sampling, and the ability to combine liver biopsy with other endoscopic goals. In this study, we present a case involving an anatomically complex, immunocompromised patient who underwent EUS-guided liver biopsy. While the samples were sufficient and progressed the management of her autoimmune hepatitis, her course was complicated by a multiloculated liver abscess. EUS liver biopsy has an excellent safety profile, but a small risk of infection remains, especially in immunocompromised patients or those with preexisting biliary obstruction.

Published: March 2024

Landslides occur when masses of rock, debris or soil move due to various factors and processes that cause land movement. The Taba Penanjung-Kepahiang route is one of the areas in Bengkulu Province that is highly prone to landslides. This causeway is the only fastest land route connecting the Bengkulu-Kepahiang area. In recent years, the road area has often been cut off due to landslides and fallen trees, which have caused road access to be cut off and obstructed and claimed lives. This study uses a Machine Learning (ML) and GIS approach with Variable Frequency Ratio using 16 independent factors obtained from the spatial database and DEM, which correlate with landslide events. This research aims to gain an in-depth understanding of the factors that cause landslides. In addition, the research focus is the development of a Disaster Mitigation Model to design and implement effective strategies to reduce the risk and impact of landslide disasters through in-depth analysis The dependent factor is the location of the landslide from the historical landslide area for the last five years, with a distribution of 70/30%. Furthermore, frequency ratio is used to analyze the correlation between conditioning factors and historical landslides. Then, the independent and dependent factors were normalized to create a landslide susceptibility map. Frequency Ratio (FR) indicates the likelihood of an event occurring, with drainage density (FR= 0.69), shear wave velocity (Vs30) (FR= 0.66), slope (FR= 0.60), and rainfall (FR= 0.55). The output of the processed data is in the table below.
Nonlinear problems inspired by the Born–Infeld theory of electrodynamics
Authors: Yang Yisong 
Published: March 2024

Abstract
It is shown that nonlinear electrodynamics of the Born–Infeld theory type may be exploited to shed insight into a few fundamental problems in theoretical physics, including rendering electromagnetic asymmetry to energetically exclude magnetic monopoles, achieving finite electromagnetic energy to relegate curvature singularities of charged black holes, and providing theoretical interpretation of equations of state of cosmic fluids via k-essence cosmology. Also discussed are some nonlinear differential equation problems.
