This research examined the impact of Basel III capital regulation (BCR) on credit risk (CR) using a sample of 25 commercial banks in Lebanon over the period 2012–2017. BCR is measured using the capital adequacy ratio (CAR) and the common equity tier one ratio (CET1 ratio), CR is measured using net provision for credit losses /total assets. To analyze the data, we constructed a hybrid model based on 3 statistical approaches. First, we modelled the dual impact of BCR and CR using probabilistic inference in the framework of Bayesian Belief Network formalism (BBN). Second, to highlight more about the correlation between BCR and CR, we used Spearman correlation test as a nonparametric approach. Third to study the simultaneous effect of CAR and CET1 ratio on CR we applied multivariate regression analysis. By analyzing the probabilistic inference for the first approach we concluded that there is an effect of BCR on CR especially for the high level of CET1 ratio, but when we investigated more if this effect is significant using the Spearman correlation test and the multivariate regression analysis, we concluded that there is no effect statistically significant of Basel III capital regulation (BCR) on credit risk (CR).

This research examined the impact of Basel III capital regulation (BCR) on profitability (P) using a sample of 25 commercial banks in Lebanon over the period 2012–2017. BCR is measured using the capital adequacy ratio (CAR) and the common equity tier one ratio (CET1 ratio), P is measured using two ratios: ROAA and ROAE. To analyze the data, we constructed a hybrid model based on three statistical approaches. First, we modelled the dual impact of BCR and P using probabilistic inference in the framework of Bayesian Belief Network formalism (BBN). Second, to highlight more about the correlation between BCR and P, we used the Spearman correlation test as a nonparametric approach. Third, to study the simultaneous effect of the BCR ratio on Profitability we apply multivariate regression analysis. By analyzing the probabilistic inference for the first approach, we concluded that there is an effect from BCR on P. When we investigated more if this effect is significance using the Spearman correlation test and the multivariate regression analysis, we concluded that that the impact of BCR on P is only found between CAR and ROAA and this regression relationship is weak because only 24.3% of the changes in ROAA variance is explained by CAR.

AbstractObjectivesEvaluate the risk factors of prolonged SARS-CoV-2 virus shedding and the impact of arbidol treatment on SARS-CoV-2 virus shedding.MethodsData were retrospective collected from adults hospitalized with COVID-19 in Wuhan Union Hospital. We described the clinical features and SARS-CoV-2 RNA shedding of patients with COVID-19 and evaluated factors associated with prolonged virus shedding by multivariate regression analysis.ResultsAmong 238 patients, the median age was 55.5 years, 57.1% were female, 92.9% (221/238) used arbidol, 58.4% (139/238) used arbidol combination with interferon. The median time from illness onset to start arbidol was 8 days (IQR, 5-14 days) and the median duration of SARS-CoV-2 virus shedding was 23 days (IQR, 17.8–30 days). SARS-CoV-2 RNA clearance was significantly delayed in patients who received arbidol >7 days after illness onset, compared with those in whom arbidol treatment was started≤7 days after illness onset (HR, 1.738 [95% CI, 1.339–2.257], P < .001). Multivariate regression analysis revealed that prolonged viral shedding was significantly associated with initiation arbidol more than seven days after symptom onset (OR 2.078, 95% CI [1.114-3.876], P .004), more than 7 days from onset of symptoms to first medical visitation (OR 3.321, 95% CI[1.559-7.073], P .002), illness onset before Jan.31, 2020 (OR 3.223, 95% CI[1.450-7.163], P .021). Arbidol combination with interferon was also significantly associated with shorter virus shedding (OR .402, 95% CI[.206-.787], P .008).ConclusionsEarly initiation of arbidol and arbidol combination with interferon as well as consulting doctor timely after illness onset were helpful for SARS-CoV-2 clearance.

Abstract Background To examine the impact of infectious diseases consultation (IDC) on the management and outcome of Staphylococcus aureus bacteremia (SAB) in children. Methods A retrospective cohort study of children with SAB at a teritary pediatric hospital (January 2009-June 2015) identified by medical record review as to whether they received an IDC for SAB at the discretion of the admitting physician or surgeon was conducted. Differences in management and outcomes for those with and without IDC were evaluated, and multivariate regression analysis was used to determine factors associated with cure. Results There were 100 patients included in the analysis. Fifty-five patients received IDC and 45 had no IDC (NIDC). Appropriate directed therapy within 24 hours (54/55 = 98.2% vs 34/45 = 75.6%, P &lt; .01), choice (54/55 = 98.2% vs 37/45 = 82.2%, P &lt; .01), dose (54/55 = 98.2% vs 36/45 = 80%, P &lt; .01), and duration (52/55 = 94.5% vs 24/45 = 53.3%, P &lt; .01) of directed antibiotic therapy were appropriate in more IDC group patients. Achievement of source control in indicated cases was also more common in the IDC group (28/32 = 87.5% vs 5/26 = 19.1%, P &lt; .01). Appropriate investigation with repeat blood cultures and echocardiograms was not significantly different. All 55 patients in the IDC group had a complete response (cure) compared with 40 of the 45 (88.9%) patients in the NIDC group: 2 patients died and 3 patients had a relapse of infection with subsequent cure. In multivariate regression analysis, methicillin-susceptible SAB and IDC were factors independently associated with cure. Conclusions Children who received IDC for SAB in a tertiary pediatric setting were more likely to have appropriate investigations and management and had improved outcomes.

In initial public offerings (IPOs), underpricing refers to pricing the issue at a price lower than its fair value which results in the listing price being much higher than the issue price. This higher information asymmetry results in more underpricing. To reduce such asymmetry, the Securities and Exchange Board of India (SEBI) introduced IPO grading and anchor investor participation in India. This article aims to assess the impact of these two factors on the underpricing of Indian IPOs over 2007–2017. This study uses multivariate regression analysis to compare the impact of graded versus ungraded IPOs and of anchor-backed versus non-anchor backed IPOs on underpricing; it finds that IPO grading and anchor investment do not have a significant overall impact on underpricing. These results justify the scrapping of mandatory IPO grading. Although insignificant, IPO grading has a greater influence on underpricing than anchor investor participation. Furthermore, the current study also analyses the subscription patterns of qualified institutional buyers (QIBs), non-institutional investors (NIIs) and retail individual investors (RIIs) and their influence on one another. Accordingly, it reveals that QIB subscription influences both NII and RII subscriptions.

Corporate governance studies in Zimbabwe have concentrated on existence of frameworks that control firms. This study focused on the corporate governance factors that are associated with firm performance in the Zimbabwean manufacturing sector. We investigated a sample of 88 companies which were operating at least 80% capacity from 2009 to 2012.Using Return on Assetst (ROA) as a measure of performance and the dependent variable, and 14 corporate governance proxies encompassing board structure, board composition and board procedures as the independent variables, a bivariate and multivariate regression analysis was performed. The results indicated that shareholder concentration, proportion of independent directors, board tenure and access to financial statements are positive and significant to firm performance in the bivariate analysis. On the multivariate regression analysis however, independent directors was positive but not significant. Researchers have not been able to agree on these factors and since corporate governance is largely endogenously determined it can be concluded that factors are influenced by country effects. Thus further studies focusing on similar countries need to be undertaken.

Purpose: The post–endovascular abdominal aortic aneurysm repair (EVAR) inflammatory response, which is very often associated with fever, has been ascribed to a wide range of proinflammatory mediators and operative events. The aim of this study was to evaluate the impact of such factors in the development of fever of noninfectious origin after elective EVAR. Materials and Methods: A retrospective analysis of prospectively collected data of patients treated with standard elective EVAR between February 2017 and December 2020 was undertaken. The database included patients’ demographics and comorbidities, as well as laboratory inflammatory markers (white blood cell count, neutrophils, and C-reactive protein [CRP]) and anatomical characteristics (sac diameter, inferior mesenteric artery [IMA] patency and diameter, number of patent lumbar arteries, internal iliac artery [IIA] patency or occlusion). Intraoperative details, such as type of stent graft material and IIA overstenting, were also analyzed. Patients with infectious postoperative complications or previously receiving systemic anti-inflammatory medication were excluded. Statistical analysis was performed by SPSS 22.0 for Windows software (IBM Corp, Armonk, New York). Results: From 332 patients treated with elective EVAR between 2017 and 2020, 268 patients (all men) were included in the analysis. The mean age was 72.1±7.5 years and the mean aneurysm diameter was 59.1±12.1 mm. Seventeen patients were excluded due to a known infection site. From the study cohort, 114 (42.5%) patients presented with fever. Multivariate regression analysis confirmed that the occlusion of IMA ≥5 mm (p<0.008) and higher CRP (p<0.001) were independent factors associated with postoperative fever. A subanalysis was performed only on patients with patent IMA before EVAR. In the multivariate regression analysis of this subgroup, IMA ≥5 mm (p=0.008), presence of dyslipidemia (p=0.037), and higher CRP (p<0.001) were related to fever. Conclusion: Occlusion of an existing wide (≥5 mm) and patent IMA prior to EVAR may contribute to the development of post-EVAR pyrexia. The CRP is a reliable marker for post-EVAR fever. Further prospective studies are needed to corroborate these findings.
