ABSTRACT
The objective of this paper is to investigate the impact of capital structure and corporate governance on firm performance. To test the hypothesis of study, data was collected from annual reports of sugar sector companies listed in PSX. This study data covers from 2015 to 2020. The results of study showed that both proxies of capital structure, i.e., D/A and D/E negatively influence the company performance. Whereas two out of three proxies of corporate governance, i.e., board size and chairman/CEO duality negatively indicate association with company performance while audit committee size has a positive impact on the company performance.
ABSTRACT
AIM: To evaluate the feasibility and safety of performing laparoscopic cholecystectomy (LC) in non-teaching rural hospitals of a developing country without intra-operative cholangiography (IOC). To evaluate the possibility of reduction of costs and hospital stay for patients undergoing LC. METHODS: A prospective analysis of patients with symptomatic benign diseases of gall bladder undergoing LC in three non-teaching rural hospitals of Kashmir Valley from Jan 2001 to Jan 2007. The cohort represented a sample of patients requiring LC, aged 13 to 78 (mean 47.2) years. Main outcome parameters included mortality, complications, re-operation, conversion to open procedure without resorting to IOC, reduction in costs borne by the hospital, and the duration of hospital stay. RESULTS: Twelve hundred and sixty-seven patients (976 females/291 males) underwent laparoscopic cholecystectomy. Twenty-three cases were converted to open procedures; 12 patients developed port site infection, nobody died because of the procedure. One patient had common bile duct (CBD) injury, 4 patients had biliary leak, and 4 patients had subcutaneous emphysema. One cholecystohepatic duct was detected and managed intraoperatively, 1 patient had retained CBD stones, while 1 patient had retained cystic duct stones. Incidental gallbladder malignancy was detected in 2 cases. No long-term complications were detected up to now. CONCLUSION: LC can be performed safely even in non-teaching rural hospitals of a developing country provided proper equipment is available and the surgeons and other team members are well trained in the procedure. It is stressed that IOC is not essential to prevent biliary tract injuries and missed CBD stones. The costs to the patient and the hospital can be minimized by using reusable instruments, intracorporeal sutures, and condoms instead of titanium clips and endobags.

OBJECTIVE: To determine the accuracy of Helicobacter pylori Stool Antigen test (HpSA), compared with endoscopic histopathology for the diagnosis of gastric Helicobecter pylori infection. STUDY DESIGN: Cross-sectional study. PLACE AND DURATION OF THE STUDY: Medical Unit ll, Abbasi Shaheed Hospital, Karachi, from March 2003 to March 2004. PATIENTS AND METHODS: A total of 50 patients underwent endoscopy for gastric antral mucosal tissue biopsy for histopathology of H.pylori and advised for HpSA. Patient's information including age, gender, past history, presenting signs and symptoms, results of HpSA and histopathology were recorded. Sensitivity analysis was performed to calculate sensitivity, specificity, and predictive values of HpSA. RESULTS: Among 50 patients, 48% males and 52% females (M: F 1: 1.08), a total of 27 (54%) were true positive while 20 (40%) were true negative. Two patients were false negative and only one was false positive. Sensitivity of HpSA was, therefore, 93.1%, specificity 95% and positive and negative predictive values were 96.42% and 90.9% respectively. CONCLUSION: Helicobacter pylori stool antigen was an accurate and reliable test for the diagnosis of gastric H. pylori infection.
