"This study attempts to analyze the determinants of capital structure in the Indonesian manufacturing industry from 2000 to 2004. Empirical hyphoteses, drawn from five independent variables are tested against a sample of 49 firms or a cross sectional data. The results show that only In total asset (size), net operating income (NOI), and return on asset (ROA) affect long-term debt to total asset (leverage). It finds a positive relation between leverage and In total asset, a negative relation between leverage and profitability (NOI and ROA). Delta sales (growth) and ownership structure have no effect on leverage. These findings are stable in 2000 through 2004."

"Interleukin (IL)-18 (interferon-g inducing factor) merupakan salah satu sitokin yang diproduksi makrofag, berperan dalam diferensiasi sel T-helper menjadi T-helper-1, dan produksi interferon g. T-helper-1 berperan dalam imunitas seluler khususnya pada infeksi virus termasuk infeksi dengue. Dilakukan studi deskriptif korelatif mengenai hubungan kadar IL-18 dengan derajat penyakit pada penderita demam dengue (DD) dan demam berdarah dengue (DBD) yang dirawat. Pada 42 subyek yang terdiri dari 20 (47,6%) penderita demam dengue dan 22 (52,3%) demam berdarah dengue (derajat I sampai IV menurut kriteria WHO tahun 1999). Didapatkan kadar IL-18 secara bermakna lebih tinggi pada DHF dibandingkan DF. Didapatkan korelasi kadar IL-18 dengan nilai hematokrit dan hitung trombosit. Studi ini menunjang kemungkinan keterlibatan IL-18 dalam patogenesis DBD pada pasien dewasa. (Med J Indones 2004; 13: 86-9)

Interleukin (IL)-18 ( interferon-g inducing factor) is one of cytokines, produced by macrophage, take part in differentiation T-helper (Th) to Th1 and interferon g producing. T-helper1 play role in cellular immunity especially in viral infection include dengue. A descriptive correlative study has done to know the correlation between IL-18 levels and disease severity in admitted dengue fever (DF) and dengue hemorrhagic fever (DHF) patients. In 42 subjects consist of 20 (47.6%) DF and 22 (53.3%) DHF (grade I to IV WHO criteria, 1999) showed that IL-18 levels significantly higher in DHF than DF patients. There are significant correlation between IL-18 levels and hematocrit and low platelet value. This study supports the possible role of IL-18 in pathogenesis DHF in adults.

"Background: cardiac function in patients with septic shock at the cellular level can be assessed by measuring troponin I and NT Pro BNP levels. Venous oxygen saturation is measured to evaluate oxygen delivery and uptake by organ tissue. Our study may provide greater knowledge and understanding on pathophysiology of cardiovascular disorder in patients with septic shock. This study aimed to evaluate the roles of echocardiography, cardiovascular biomarkers, venous oxygen saturation and renal function as predictors of mortality rate in patients with septic shock.Methods: this is a prospective cohort study in patients with infections, hypotension (MAP < 65 mmHg) and serum lactate level of > 2 mmol/L. On the first and fifth days, septic patients underwent echocardiography and blood tests. Statistical analysis used in our study included t-test or Mann-Whitney test for numeric data and chi-square test for nominal data of two-variable groups; while for multivariate analysis, we used Cox Regression model.Results: on 10 days of observation, we found 64 (58%) patients died and 47 (42%) patients survived. The mean age of patients was 48 (SD 18) years. Patients with abnormal left ventricular ejection fraction (LVEF) had 1.6 times greater risk of mortality than those with normal LVEF (RR 1.6; p = 0.034). Patients with abnormal troponin I level showed higher risk of mortality as many as 1.6 times (RR: 1.6; p = 0.004). Patients with impaired renal function had 1.5 times risk of mortality (RR 1.5; p = 0.024). Patients with abnormal troponin I level and/or impaired renal function showed increased mortality risk; however, those with normal troponin I level and impaired renal function also showed increased mortality risk. Multivariate analysis revealed that left ventricular ejection fraction and troponin I level may serve as predictors of mortality in patients with septic shock. (HR 1.99; 95% CI: 1.099 - 3.956 ; p = 0.047 and HR: 1.83 ; 95%CI: 1.049 - 3,215 ; p = 0.043). Conclusion: left ventricular ejection fraction and biomarkers such as troponin I level are predictors of mortality in septic shock patients."
