Background: The perfect repair of damaged skin has always been a constant goal for scientists; however, the repair and reconstruction of skin is still a major problem and challenge in injury and burns medicine. Human amniotic membrane (hAM), with its good mechanical properties and anti‐inflammatory, antioxidant and antimicrobial benefits, containing growth factors that promote wound healing, has evolved over the last few decades from simple skin sheets to high‐tech dressings, such as being made into nanocomposites, hydrogels, powders, and electrostatically spun scaffolds. This paper aims to explore the historical development, applications, trends, and research hotspots of hAM in wound healing. Methods: We examined 2660 publications indexed in the Web of Science Core Collection (WoSCC) from January 1, 1975 to July 12, 2023. Utilizing bibliometric methods, we employed VOSviewer, CiteSpace, and R‐bibliometrix to characterize general information, identify development trends, and highlight research hotspots. Subsequently, we identified a collection of high‐quality English articles focusing on the roles of human amniotic epithelial stem cells (hAESCs), human amniotic mesenchymal stem cells (hAMSCs), and amniotic membrane (AM) scaffolds in regenerative medicine and tissue engineering. Results: Bibliometric analysis identified Udice–French Research Universities as the most productive affiliation and Tseng S.C.G. as the most prolific author. Keyword analysis, historical direct quotations network, and thematic analysis helped us review the historical and major themes in this field. Our examination included the knowledge structure, global status, trends, and research hotspots regarding the application of hAM in wound healing. Our findings indicate that contemporary research emphasizes the preparation and application of products derived from hAM. Notably, both hAM and the cells isolated from it – hADSCs and hAESCs are prominent and promising areas of research in regenerative medicine and tissue engineering. Conclusion: This research delivers a comprehensive understanding of the knowledge frameworks, global dynamics, emerging patterns, and primary research foci in the realm of hAM applications for wound healing. The field is rapidly evolving, and our findings offer valuable insights for researchers. Future research outcomes are anticipated to be applied in clinical practice, enhancing methods for disease prevention, diagnosis, and treatment. [ABSTRACT FROM AUTHOR]

To investigate temporal patterns, sociodemographic gradients, and structural breaks in adolescent marijuana use in the United States from 1991 to 2018, we used hierarchical age-period-cohort logistic regression models to distinguish temporal effects of marijuana use among 8th, 10th, and 12th graders from 28 waves of the Monitoring the Future survey (1991–2018). Structural breaks in period effects were further detected via a dynamic-programing–based method. Net of other effects, we found a clear age-related increase in the probability of marijuana use (10.46%, 23.17%, and 31.19% for 8th, 10th, and 12th graders, respectively). Period effects showed a substantial increase over time (from 16.23% in 2006 to 26.38% in 2018), while cohort effects remained stable throughout the study period. Risk of adolescent marijuana use varied by sex, racial group, family status, and parental education. Significant structural breaks during 1995–1996, 2006–2008, and 2011–2013 were identified in different subpopulations. A steady increase in marijuana use among adolescents during the latter years of this time period was identified. Adolescents who were male, were non-Black, lived in nonintact families, and had less educated parents were especially at risk of marijuana usage. Trends in adolescent marijuana use changed significantly during times of economic crisis. [ABSTRACT FROM AUTHOR]

This study shows that managers adjust corporate payout policies to counteract intensified short‐selling pressures following the removal of a short‐selling constraint. We use a controlled experiment, the Regulation SHO pilot program, to find that changing the short‐selling rule brings small companies to increase cash dividends, but not to repurchase more shares. Because paying dividends is costly, it is acknowledged as a more reliable signal of stock undervaluation than share repurchase. While our evidence suggests that companies select this payout strategy to deter predatory short sellers, it also shows that a short‐selling activity has a causal effect on corporate payout decisions.

This paper studies the relationship between market frictions and political connections in determining financial constraints. We develop a novel index to measure the depth of political connections (PC) at the firm level and provide robust empirical evidence that firms in China actively build PC to alleviate the costs of market frictions. Specifically, we find that firms facing severe market frictions are not as financially constrained as expected. This is because these firms also possess strong PC, which alleviate the costs of market frictions. We find that market frictions can significantly affect financial constraints in Chinese firms, but only for those firms with modest levels of PC. [ABSTRACT FROM AUTHOR]

Studies investigating market reactions to changes in capital structure aim to find the impact of private information conveyed. However, these studies ignore that financial decisions are not made randomly but are conditional on managers' private information. Using a sample of U.S. leverage-increasing public companies with public long-term debt offerings, we find that debt offerings convey no new information to the markets after considering the conditionality of decisions. We also show that results can be biased if the deterministic role played by private information ex ante is omitted, which may explain the conflicting valuation evidence found in the literature.

Foreign banks in China have faced strict regulatory requirements that were not imposed on domestic banks and as such they have performed poorly in profitability rankings. Recent changes in the Chinese regulatory requirements prompt us to consider whether foreign banks are now on an equal footing with the Chinese domestic banks. Using Cobb-Douglas stochastic frontier analysis with total income as the dependent variable, we find no significant performance difference between foreign and domestic banks. However, robustness testing using the individual components of total income as dependent variables reveals that foreign banks need to improve efficiency of their income generation.

Literature streams disagree about the capacity of investment-cash flow sensitivity (ICFS) to measure both investment thirst and financial constraint. We argue that ICFS measures the former but not the latter. Therefore, we use Fazzari et al.'s study (1988) to develop a model to test the relationship between ICFS and financial constraint, but extend that model using Kornai (1979) to include investment thirst. We demonstrate: because the ICFS-financial constraint relationship varies, ICFS cannot measure financial constraint. Conversely, using a natural experiment of China's Four Trillion Stimulus policy, we show ICFS significantly and positively correlates with investment thirst after controlling for financial constraint.

We examine whether disclosure of complex information events reduces information asymmetry by investigating the long- and short-term impact of firms' disclosure of debt covenant violations on the probability of informed trading. We argue debt covenant violation disclosures provide informed agents with a long window of opportunity to trade on their private information largely due to the uncertainty arising from the debt renegotiation process. We find the probability of informed trading is greater after the disclosure, particularly when the violation outcomes are unresolved or where there is concern about possible future violations.

Background: Burn injuries with ≥70% total body surface area (TBSA) are especially acute and life-threatening, leading to severe complications and terrible prognosis, while a powerful model for prediction of overall survival (OS) is lacked. The objective of this study is to identify prognostic factors for the OS of patients with burn injury ≥70% TBSA, construct and validate a feasible predictive model., Materials and Methods: Patients diagnosed with burns ≥70% TBSA admitted and treated between 2010 and 2020 in our hospital were included. A cohort of the patients from the Kunshan explosion were assigned as the validation set. The Chi-square test and K-M survival analysis were conducted to identify potential predictors for OS. Then, multi-variate Cox regression analysis was performed to identify the independent factors. Afterwards, we constructed a nomogram to predict OS probability. Finally, the Kunshan cohort was applied as an external validation set., Results: Gender, the percentage of third- and fourth-degree burn as well as organ dysfunction were identified as significant independent factors. A nomogram only based on the factors of the individuals was built and evidenced to have promising predictive accuracy, accordance, and discrimination by both internal and external validation., Conclusions: This study recognized significant influencing factors for the OS of patients with burns ≥70% TBSA. Furthermore, our nomogram proved to be an effective tool for doctors to quickly evaluate patients' outcomes and make appropriate clinical decisions at an early stage of treatment., (Copyright © 2024 The Author(s).
