The impact of green technology innovation and firm default risk: benefit effect or risk effect?-evidence from the panel data on Chinese manufacturing firms.

In the context of China's strategic goal of carbon neutrality, the realization of green technology innovation to reduce the risk of manufacturing default will help promote the green transformation of firms and achieve high-quality economic development. The study explored the relationship between green technology innovation and default risk by taking the manufacturing industry of listed enterprises in China from 2001 to 2020 as research samples. The results showed that green technology innovation is negatively correlated with default risk. Moreover, the heterogeneity analysis showed that the benefit effect of heavy-polluting enterprises, state-owned enterprises, and large-scale enterprises was more significant. The mechanism analysis showed that green technology innovation can reduce default risk through market position and capital structure. In addition, the study further distinguished that environmental protection tax was conducive to green technology innovation to reduce the occurrence of default risk. In theory, the study expanded the research paradigm between green technology innovation and default risk in theory, and provided new evidence and enlightenment for reducing the default risk of enterprises and supported the green and sustainable development of enterprises in practice.

The neglected association between central obesity markers and abdominal aortic aneurysm presence: A systematic review and meta-analysis.

Purpose: To review the association between central obesity and abdominal aortic aneurysm (AAA). Materials and methods: The PubMed, Web of Sciences, Embase, The China national knowledge infrastructure (CNKI), and Cochrane Library were searched up to April 30, 2022. Researches includes investigation of the relationship between central obesity markers and AAA. Included studies must use recognized measures of central obesity, i.e., waist circumference (WC) and waist-to-hip ratio (WHR), or use imaging techniques to calculate abdominal fat distribution, such as computed tomography (CT) imaging. Results: Eleven clinical researches were identified of which eight discussed the association between physical examination and AAA, and three studies mainly focused on abdominal fat volume (AFV). Seven researches concluded that there was a positive correlation between markers of central obesity and AAA. Three studies found no significant link between markers of central obesity and AAA. One of the remaining studies reported different results for each sex. Three studies pooled in a meta-analysis identified correlation between central obesity and AAA presence (RR = 1.29; 95% confidence interval, 1.14-1.46). Conclusion: Central obesity plays a role in the risk of AAA. Standardized central obesity markers may be predictors of AAA. However, there was no association between abdominal fat volume and AAA. Additional relevant evidence and specific mechanisms warrant further study.

Comparison of efficiency and safety of open surgery, hybrid surgery and endovascular repair for the treatment of thoracoabdominal aneurysms: a systemic review and network meta-analysis.

Objective: The objective of this study was to perform a network meta-analysis (NMA) to assess the efficacy and safety of three different surgical interventions- open surgical repair (OSR), hybrid surgical repair (HSR), and endovascular repair (EVAR)- for the treatment of thoracoabdominal aortic aneurysms (TAAAs). Methods: Electronic repositories like PubMed, Embase, Web of Science, Scopus, ScienceDirect, the Cochrane library, Clinical trial, and China National Knowledge Infrastructure (CNKI) were systematically searched to identify studies that compared the efficacy of OSR, HSR, and EVAR with endografts for the treatment of TAAAs until December 24th, 2022. Random-effects and fixed-effects models were employed to analyze the data gathered in a network meta-analysis. The study's primary outcomes of interest encompassed in-hospital mortality, long-term survival rate, and postoperative complications. Results: Eleven comparative studies meet inclusion criterias. There were 2,222 patients in OSR, 1,574 patients in EVAR and 537 patients in HSR. EVAR has lower one-month mortality than OSR (RR: 0.31; 95% CI: 0.17-0.70) and HSR (RR: 0.37; 95% CI: 0.22-0.71), and lower incident rate of renal complications than HSR (RR: 0.20; 95% CI: 0.08-0.43) and OSR (RR: 0.34; 95% CI: 0.16-0.65). Nonetheless, there was no noteworthy discrepancy identified in the long-term survival rates of these procedures. Conclusions: As compared with OSR, HSR, and EVAR, EVER has lower one-month mortality, and lower incident rates of complications. Systematic review registration: PROSPERO (CRD42022313829).

Causal relationship between health insurance and overall health status of children: Insights from Pakistan.

Evaluating the impact of health insurance always remains a methodologically challenging endeavor due to the absence of sample randomization. This paper evaluates the impact of health insurance on the health status of children in Pakistan using the data of the Multiple Indicator Cluster Survey (MICS) for Punjab, Pakistan, from 2017 to 2018. The study adopted the propensity score matching (PSM) method to address the sample selection bias. The sample is matched on potential covariates such as mother characteristics (education level), household head characteristics (gender, age, and education), and other household conditions (such as home dwelling, internet access, wealth index, migration member, number of children residing in the home, as child illness, etc.). The findings revealed that children with insurance have considerably better health than non-insured, at a 1% significance level. The results confirm that health insurance is not a luxury but a need that improves children's overall health. In this regard, governments should enhance and expand programs related to health insurance, especially for children. Health insurance programs will not only help poor people but also improve the overall infrastructure of health services in the country.

[Clinical Analysis of Pediatric Acute Leukemia Complicated with Septic Shock].

OBJECTIVE: To analyze the clinical characteristics of predictors in pediatric acute leukemia complicated with septic shock and explore the prognostic factors. METHODS: The clinical characteristics of 70 children with acute leukemia and complicated with septic shock hospitalized in Sun Yat-sen Memorial Hospital from March 2012 to March 2021 were retrospectively analyzed. The clinical characteristics of patients in survival group and death group were analyzed and compared. Multiple logistic regression was used to test for predictors of death. RESULTS: Among the 70 children, 41 were males and 29 were females, with a median age of 7.0 (1.0-15.0) years old. 81.4% were hospital acquired infections. The pathogens were mostly Gram-negative bacteria (50/66, 75.8%) and the clinical manifestations were cold shock. Mortality rate was 34.3% (24/70). The length of hospitalization, duration of fever and antibiotic exposure longevity before the onset of septic shock were significantly different between survival group and death group. At septic shock onset, compared with the survival group, patients in the death group were younger, had lower platelet counts and higher levels of C-reactive protein and procalcitonin, and were more likely to have acute heart failure and more mechanical ventilation (all p<0.05). The results of multivariable analysis showed that mortality was independently associated with pediatric sequential organ failure assessment score (pSOFA) (odds ratio: 1.616, 95% CI: 1.160-2.251, p=0.005) and acute heart failure (odds ratio: 18.308, 95% CI: 1.939-172.911, p=0.011). In addition, the ROC curve analysis showed that pSOFA score had AUC of 0.8551 (95% CI: 0.7607-0.9495, p<0.001) predicting PICU mortality and its best predictive value was >9.5 (sensitivity 75.0%, specificity 87.0%). CONCLUSION: Pediatric acute leukemia complicated with septic shock is characterized as rapid deterioration and high mortality. A pSOFA score greater than 9.5 and acute heart failure are associated with poor outcomes.
