The effect of culture on Corporate Governance Practices in Nigeria

This study focuses on the effect of culture on the application of corporate governance practices in Nigeria. Corporate governance has been receiving serious attention in emerging markets over the past two decades. But relatively little attention has been given to the study on corporate governance in a country study. The current situations in Nigerian public and private sectors such as the corporate scandal resulting from Lever Brothers Nigeria plc, Siemens, Shell, Halliburton, and Cadbury Nigeria plc, have shown that the issue of fraud, corruption, and corporate scandals cannot be overlooked. Most top management, as this study argues, bring in beliefs acquired from their early childhood into their senior management roles and responsibilities. This study adopts a grounded theory and reports on the effect of culture on the implementation of corporate governance in Nigeria. Based on the interview with 32 staffs, this study identifies the effect of culture that shapes corporate governance and they include abuse of power by top management, weak legal framework, poor recruitment and ineffective control. Although having efficient corporate governance is worth pursuing, this depends on the power of top management, the strength of internal control procedures and the legal framework put in place by management

Concomitant Tricuspid Repair in Patients with Degenerative Mitral Regurgitation

Background: Tricuspid regurgitation is common in patients with severe degenerative mitral regurgitation. However, the evidence base is insufficient to inform a decision about whether to perform tricuspid-valve repair during mitral-valve surgery in patients who have moderate tricuspid regurgitation or less-than-moderate regurgitation with annular dilatation. Methods: We randomly assigned 401 patients who were undergoing mitral-valve surgery for degenerative mitral regurgitation to receive a procedure with or without tricuspid annuloplasty (TA). The primary 2-year end point was a composite of reoperation for tricuspid regurgitation, progression of tricuspid regurgitation by two grades from baseline or the presence of severe tricuspid regurgitation, or death. Results: Patients who underwent mitral-valve surgery plus TA had fewer primary-end-point events than those who underwent mitral-valve surgery alone (3.9% vs. 10.2%) (relative risk, 0.37; 95% confidence interval [CI], 0.16 to 0.86; P = 0.02). Two-year mortality was 3.2% in the surgery-plus-TA group and 4.5% in the surgery-alone group (relative risk, 0.69; 95% CI, 0.25 to 1.88). The 2-year prevalence of progression of tricuspid regurgitation was lower in the surgery-plus-TA group than in the surgery-alone group (0.6% vs. 6.1%; relative risk, 0.09; 95% CI, 0.01 to 0.69). The frequencies of major adverse cardiac and cerebrovascular events, functional status, and quality of life were similar in the two groups at 2 years, although the incidence of permanent pacemaker implantation was higher in the surgery-plus-TA group than in the surgery-alone group (14.1% vs. 2.5%; rate ratio, 5.75; 95% CI, 2.27 to 14.60). Conclusions: Among patients undergoing mitral-valve surgery, those who also received TA had a lower incidence of a primary-end-point event than those who underwent mitral-valve surgery alone at 2 years, a reduction that was driven by less frequent progression to severe tricuspid regurgitation. Tricuspid repair resulted in more frequent permanent pacemaker implantation. Whether reduced progression of tricuspid regurgitation results in long-term clinical benefit can be determined only with longer follow-up.
