Does mandatory audit rotation affect insider trading? Evidence from China
Authors: Xiao He , Xi Jianqun , Meng Hanjie 
Published: January 2023

PurposeThis study aims to investigate the impact of mandatory audit partner rotation (MAPR) on Chinese listed firms’ insider trading, as well as the moderating effects of firm characteristics on this impact. The economic mechanism behind this impact is also explored.Design/methodology/approachThis study conducts a regression analysis on firms associated with mandatory and voluntary audit partner rotation based on 2009–2019 firm data and examines whether corporate insiders of these two types of firms increase their share sales within 12 months before their financial statements are submitted to a new rotated auditor.FindingsClient firms’ corporate insiders increase their share sales within 12 months before their financial statements are submitted to a new mandatory rotated auditor. In addition, such an association is less pronounced for client firms that changed from Big 4 auditors to those with higher financial constraints. This is more pronounced for client firms with higher information asymmetry. The economic mechanism of the finding is that is the MAPR implementation reduces earnings management activities from client firms. Moreover, client firms’ buy-and-hold stock returns decline in the first year after MAPR.Research limitations/implicationsThis study should assist investors, corporate shareholders and Chinese policymakers. Investors can be well protected through the adoption of MAPR because upcoming auditors enhance the audit quality of clients by restraining managers’ manipulation of reported earnings and declining firms’ insider trading afterwards. Investors, Chinese policymakers and corporate shareholders should pay more attention to firms’ financial report quality, auditor selection, financial situation, corporate governance and the information environment. Explicitly, firms with less transparent financial report quality, non-big 4 auditors and fewer financial constraints are more likely to be involved in insider trading.Originality/valueTo the best of the authors’ knowledge, none of the extant studies have examined the impact of MAPR on insider sales. This study extends the research on the effect of the audit process on firm market performance by investigating the impact of audit partner rotation policy on insider trading behaviors.

AbstractWe evaluated the effects of Laoshan cherry as a food or dietary supplement on relieving the symptoms of acute gouty arthritis in rats induced by urate crystals. Rats in groups of 10 were given Laoshan cherry functional extracts at doses of 5, 10, and 20 mg/kg by oral gavage for 21 days and then injected with a sodium nitrate suspension in the rear ankle area as an induced acute gouty arthritis model. The ankle swelling and inflammations in the model (no treatment) group increased significantly compared with blank group; the ankle inflammations reduced in experimental groups receiving three different doses of the cherry extract and the joint swelling reduced in the high‐dose group by 43% compared with the model group. Serum uric acid and xanthine oxidase activities were also elevated in the model group and these parameters were reduced by a maximum of 8% and 33%, respectively, in the rats receiving the cherry extracts. The serum levels of the inflammatory cytokine IL‐1β in the high‐dose group decreased by 12% compared with the model group. These results demonstrated that the cherries possess a functional substance that has a significant alleviating effect on the symptoms of gouty arthritis in rats induced by sodium urate injection.

Published: January 2023

AbstractThe aim of this work is to produce bioactive films suitable for aerobic packaging applications by combining the bioactivity of Spirulina platensis protein concentrate (PC; 1% and 2% w/w), the sustainable nature of bovine gelatin (Ge), and sodium alginate dialdehyde (ADA, 5% w/w) as Schiff base crosslinking agent. PC was obtained by an optimized acid–base extraction process and characterized. PC showed a dose‐dependent radical scavenging activity (RSA; IC50 = 24.3 mg/L) related to its high content of C‐phycocyanin and total phenolic compounds (32.44 ± 1.37 mg gallic acid equivalents per gram of PC). As a general trend, crosslinking decreased the water solubility, improved mechanical properties, and helped improve RSA of Ge–ADA–PC films. Ge–5ADA–2PC film recorded best compromise between solubility (only 33.6%), high UV barrier (0.134% transmittance at 400 nm), reasonable extensibility (217.00 ± 2.34%), tensile strength (3.50 ± 0.43 MPa), water vapor permeability (2.00 ± 0.17 × 10−12 kg·m/m2·Pa·s), and RSA (44.70 ± 2.19%). Wrapping hake fillets in this filmdelayed lipid oxidation during storage under refrigerated conditions for 11 days, maintaining the thiobarbituric acid index below 0.5 mg malonaldehyde/kg muscle. Results suggest that Ge–ADA–PC films have potential as aerobic packaging materials for oxidation‐sensitive food.Practical ApplicationThe combination of gelatin, alginate dialdehyde and Spirulina platensis protein concentrate gave rise to fully biobased films with reduced water solubility and enhanced antioxidant activity, which were able to delay the secondary lipid oxidation of refrigerated seafood. This study also shows the potential of cyanobacteria as renewable resources of high‐value ingredients for the design of active and intelligent aerobic packaging solutions.

ObjectivesChemotherapy without radiation therapy for locally advanced rectal cancer (LARC) has attracted increasing attention, but the optimal schema remains controversial. In this study, we aimed to assess the efficacy and toxicity of neoadjuvant chemotherapy (nCT) of two regimens for patients with mid‐low baseline resectable LARC.MethodsA retrospective study was performed in 131 patients with baseline resectable LARC in a single center between April 2016 and August 2020. All patients received four cycles of neoadjuvant CapeOX or mFOLFOX6 before surgery. Clinical characteristics, pathological response, and survival status were then assessed.ResultsAfter a 1:1 propensity score matching, 96 patients were enrolled, including 48 receiving CapeOX and 48 receiving mFOLFOX6. The objective regression rates were 50.00% and 58.33%, and the pathological complete response rates were 6.25% and 8.33%, respectively, in the CapeOX and mFOLFOX6 groups. Patients who received mFOLFOX6 had a better tumor regression grade (TRG) than those who received CapeOX (P = 0.005). Patients in both groups had similar survival outcomes.ConclusionsThe nCT has shown promising tumor response and survival outcomes, which can be a treatment option for baseline resectable LARC. For the two regimens, mFOLFOX6 provided better TRG than CapeOX, although no differences were observed in disease‐free survival and OS.
An Evaluation of Phase Behaviors of the Oil‐Gas‐Water System in the Displacement of Crude Oil with CO2
Authors: ZHANG Angang , FAN Zifei , HE Jun 
Published: January 2023

AbstractCO2dissolution into an aqueous phase and water evaporation into a gaseous phase takes place during CO2injection into an oil reservoir. This study aims to evaluate the phase behaviors of the oil‐gas‐water system in the displacement of crude oil by CO2. The composition of the JL oilfield in the northeast of China is taken as an example. The flash calculation of the oil‐gas‐water system was performed, based on the method presented by Li and Nghiem. The research results show that CO2dissolution in the aqueous phase declines as the NaCl concentration in formation water rises. CO2injection is beneficial for the evaporation of formation water. The NaCl concentration in formation water has little effect on water evaporation and dissolved‐gas escape. When the injection‐gas mole fraction of CO2is 0.5, CO2injection can reverse the phase behavior of the petroleum mixture and the oil‐gas system is converted to a pure gas‐condensate system. For CO2injection, water vapor has little effect on the miscibility of multiple contacts, but can reduce the miscibility of the first contact.

AbstractJiama is a giant, high‐grade porphyry copper system in the Gangdese metallogenic belt, Tibet. Multistage intermediate–felsic porphyries intruded in this deposit, some of which are strongly associated with copper‐polymetallic mineralization. These ore‐bearing porphyries include monzogranite, granodiorite, and quartz diorite porphyries. A new granite aplite dyke was found in the south of Jiama. Its age, genesis, and relationship with ore‐related magmatism are obscure. Here, its emplacement age and petrogenesis were determined using mineralogy, zircon U‐Pb dating, geochemistry, and Sr‐Nd‐Pb isotope studies. The zircon LA‐ICP‐MS U‐Pb age of the aplite dyke is 16.66 ± 0.21 Ma (n = 14, MSWD = 0.66), earlier than that of the ore‐bearing porphyries (∼15 Ma) in Jiama. Furthermore, the aplite exhibits high amounts of silicon (SiO2 = 73.39%–74.74%), potassium (K2O = 5.12%–6.61%), aluminum (Al2O3 = 14.25%–14.69%), and light/heavy rare earth elements (LREE/HREE = 12.12–16.19) as well as negative europium (δEu = 0.47–0.72) and weak negative cerium anomalies (δCe = 0.84–0.93). The aplite dyke is characteristic of metaluminous–peraluminous I‐type granite, which is rich in large‐ion lithophile elements (Rb, Ba, Th and U) and depleted in high‐field‐strength elements (Nb, P and Ti). The aplite dyke and ore‐bearing porphyries in the Jiama deposit are the results of a partial melting of the juvenile lower crust, according to whole‐rock geochemistry and Sr‐Nd‐Pb isotope data, but the dyke and ore‐bearing porphyries were emplaced from the same magma chamber at different times. Thus, the aplite dyke shows the composition of the early evolution stage of shallow magma in the Jiama deposit and is the product of rapid condensation and crystallization.

AbstractObjectiveThere are conflicting data regarding the accuracy of thoracic point‐of‐care ultrasound (POCUS) in detecting traumatic pneumothorax (PTX). The purpose of our study was to determine the accuracy of thoracic POCUS performed by emergency physicians for the detection of clinically significant PTX in blunt and penetrating trauma patients.MethodsWe conducted a retrospective institutional review board–approved study of trauma patients 15 years or older presenting to our urban Level I academic trauma center from December 2021 to June 2022. All study patients were imaged with single‐view chest radiography (CXR) and thoracic POCUS. The presence or absence of PTX was determined by multidetector computed tomography (CT) or CXR and ultrasound (US) with tube thoracostomy placement.ResultsA total of 846 patients were included, with 803 (95%) sustaining blunt trauma. POCUS identified 13/15 clinically significant PTXs (defined as ≥35 mm of pleural separation on a blinded overread or placement of a tube thoracostomy prior to CT) with a sensitivity of 87% (95% confidence interval [CI] 58–97), specificity of 100% (95% CI 99–100), positive predictive value of 81% (95% CI 54%–95%), and negative predictive value of 100% (95% CI 99%–100%). The positive likelihood ratio was 484 and the negative likelihood ratio was 0.1. CXR identified eight (53%) clinically significant PTXs, with a sensitivity of 53% (95% CI 27%–78%) and a specificity of 100%, when correlated with the CT. The most common reason for a missed PTX identified on expert‐blinded overread was failure to recognize a lung point sign that was present on US.ConclusionsThoracic POCUS accurately identifies the majority of clinically significant PTXs in both blunt and penetrating trauma patients. Common themes for false‐negative thoracic US in the expert‐blinded overread process identified key gaps in training to inspire US education and medical education research.
Enhancing bank transparency: Financial reporting quality, fraudulent peers and social capital
Authors: Mattei Marco Maria , Platikanova Petya 
Published: January 2023

AbstractThis study examines the role of social norms in financial markets by relating bank transparency to social capital. Using comprehensive data on commercial banks, we provide empirical evidence that high social capital contributes to more transparent financial reporting, thereby enabling more precise risk assessments and promoting financial stability. We find that the effect of social capital is more pronounced when commercial banks are more complex and disclosure incentives of bank managers are strong. Our results suggest that more opaque reporting by peers explains lower transparency but financial misreporting is less contagious when social capital is high. Our study suggests that social capital can effectively improve reporting transparency when other mechanisms are not effective, thus securing financial system stability.

Published: January 2023

ABSTRACTAimsThis systematic review aimed to compare the efficiency of orifice barriers in preventing coronal microleakage in vitro.MethodsArticles published in English, German and Chinese were searched for studies describing microleakage assays for the bacterial penetration of root canal‐treated teeth in vitro. The final sample included 18 articles for review and meta‐analysis. Risk ratios and confidence intervals were determined for dichotomous variables. Ten publications using bacterial leakage models contributed to the meta‐analysis.ResultsThe addition of orifice barriers to a root canal filling was overall effective, shown by risk ratios (RR) and 95% confidence intervals (CI) demonstrating reduced microleakage with glass ionomer cement (GIC) (RR 0.37, 95% CI 0.26–0.53, P < 0.001), resin‐modified GIC (RR 0.32, 95% CI 0.15–0.67, P = 0.01), composite resin (RR 0.54, 95% CI 0.38–0.75, P < 0.001), mineral trioxide aggregate (MTA) (RR 0.25, 95% CI 0.12–0.52, P < 0.001) and Cavit (RR 0.23, 95% CI 0.14–0.39, P < 0.001). There were no significant differences between GIC, resin‐modified GIC, composite resin and MTA orifice barriers.ConclusionsPlacement of an orifice barrier over the root canal filling is effective in the prevention of coronal microleakage in vitro. Other parameters may also affect the effectiveness of orifice barriers, including thickness and duration of exposure to the oral environment. © 2023 Australian Dental Association.

AbstractThis study evaluated, through micro‐computed tomography (micro‐CT), the volume of irrigant diffusion by different techniques of final agitation. Sixty mesiobuccal canals were scanned in a micro‐CT and standardised according to the volume. They were instrumented with the MTwo 40/04 system and using the Terebrix 35 contrast solution as irrigant, were divided into six groups (n = 10): Conventional irrigation with syringe and needle (CI), EndoActivator (EA), EasyClean (EC), RinsEndo (RE), Utrasonic agitation (UI) and XP‐Clean (XP). A second micro‐CT scan was performed and the total irrigant volume and in the final 3 mm apical were determined. The data were analysed using the Anova, Kruskal–Wallis and Dunn tests (p < 0.05). UI and XP showed a higher percentage of total diffusion than CI, EA and RS groups (p < 0.05). In apical diffusion, there was no significant difference between groups (p > 0.05). The final agitation system increases the diffusion of irrigating agents inside the root canal.

Published: January 2023

AbstractObservational studies on the association between citrus fruit intake and risk of renal cell carcinoma (RCC) have reported inconsistent results. We quantitatively assessed this association by conducting a meta‐analysis. PubMed and Embase databases search was conducted including relevant studies published up to January, 2020. We included epidemiological studies that reported relative risks (RRs) or odds ratios (ORs) with 95% confidence intervals (CIs) for the association between citrus fruit intake and RCC risk. A total of eight epidemiological studies consisting of five cohort and three case‐control studies were included. The overall analysis showed a significantly reduced risk of RCC for high intake of citrus fruit (OR = 0.84, 95% CI 0.73–0.95). No heterogeneity was detected among the included studies (p = 0.497 for heterogeneity; I2 = 0). There was no significant publication bias by Begg's test (p = 0.266) or Egger's test (P = 0.578). A statistically significant association between citrus fruit intake and RCC was observed in case‐control studies (OR = 0.84, 95% CI 0.71–0.98), while no association was observed in cohort studies (OR = 0.84, 95% CI 0.64–1.05). In addition, the dose–response analysis indicated that the RCC risk reduced by 13% (95%CI 1.0%‐27%, p = 0.04 for heterogeneity) for each 100 grams per day increment of citrus fruit intake. In summary, our findings suggest an inverse association between citrus fruit intake and RCC incidence.

AbstractIntroductionOpportunistic salpingectomy (OS) refers to additional removal of the fallopian tubes during abdominal surgery performed for another medical indication, as prevention for ovarian cancer. As OS has been inconsistently implemented, its clinical practice varies worldwide. To reduce this variation, insight is required into current clinical practice and its determinants. Therefore, the study aim was to determine the implementation of counseling and performance of OS between 2015 and 2018, and its patient, surgical, physician, and hospital characteristics.Material and methodsRetrospective study using electronic medical records from six different Dutch hospitals: two academic, two large teaching, and two non‐teaching hospitals. Patients were considered eligible for OS if they underwent elective non‐obstetric abdominal surgery for a gynecological indication from January 2015 through December 2018. Primary outcomes were uptake of counseling and performance of OS. Multilevel multivariable logistic regression analyses were conducted to identify characteristics associated with OS.ResultsA total of 3214 patients underwent elective non‐obstetric abdominal surgery for a gynecological indication and were eligible for OS. Counseling on OS increased significantly from 2.9% in 2015 to 29.4% in 2018. In this period, 440 patients were counseled on OS, of which 95.9% chose OS. Performance of OS increased significantly from 6.9% in 2015 to 44.5% in 2018. Counseling for and performance of OS were more likely in patients who had surgery by laparoscopic approach, were counseled by a gynecological resident, or had more than three contact moments before surgery. Additionally, OS was less likely in patients who had vaginal surgery.ConclusionsAlthough the uptake of OS increased from 2015 to 2018, the majority of patients who were eligible for OS were not counseled and did not undergo OS. Its clinical practice varies on patient, surgery, and physician characteristics. Therefore, an implementation strategy tailored to associated determinants is recommended.

Published: January 2023

AbstractBackgroundNail stickers and nail tips are increasingly used nail products in Korea, and the rest of the world. However, no studies have examined if these specific consumer products might contain nickel, cobalt, and/or chromium, that is, metals known to provoke contact allergy.ObjectiveWe aimed to assess the release and content of nickel, cobalt, and chromium in nail stickers and tips by performing qualitative and quantitative analyses, respectively, of 50 convenience samples purchased in Korea.MethodsEighty‐six qualitative spot tests were performed to determine the release of nickel, cobalt, and chromium on 35 nail stickers and 15 nail tips across five brands. Subsequently, the metal contents were quantified using inductively coupled plasma‐optical mass spectrometry (ICP‐MS).ResultsAccording to the spot tests, nickel was released in 7/86 (8.1%) tests before and 10/86 (11.6%) tests after exposure to artificial sweat. Cobalt and chromium (VI) spot test results were negative. However, ICP‐MS detected nickel, cobalt, and chromium in 11%, 6.3%, and 16.7% of the samples, respectively. Detection rates were higher in nail tips than in stickers and were most common in rhinestones.ConclusionNail stickers and tips may contain nickel, cobalt, and/or chromium.
