Abstract

BACKGROUND: Propofol is an intravenous anesthetic used worldwide as an anesthesia induction and maintenance agent. Propofol also used as sedation agent in Intensive Care Unit (ICU). Despite it’s usual anesthesia properties, propofol has an unique pharmacologic characteristic, especially as antioxidant and stress response reduction. These advantages suggested propofol has positive effects when used as an anesthesia agent in surgery or sedation in ICU in conditions when high stress and free radical level are released.CONTENT:Stress response and free radical can be elevated in various conditions including surgery or during care in ICU, especially critical ill patient. Cortisol is a major stress hormone that influences metabolism, cardiovascular and central nervous system, either in acute or chronic phase. Oxidative stress was marked by free radical elevation called Radical Oxygen Species (ROS). Combination of both elements (cortisol and ROS) can worsen patient condition. Propofol with anti-stress and antioxidant properties could be used to reduce stress response and attenuate free radical level in order to improve patient condition.SUMMARY: The anti-stress and antioxidant properties of Propofol are interesting, because these benefits can be added as adjunctive therapy when propofol was used as an anesthetic agent in surgery and a sedation in ICU.KEYWORDS: propofol, stress response, antioxidant

Abstract

BACKGROUND: Peroxisome proliferator-activated receptor (PPAR)-γ, or also known as nuclear receptor subfamily 1 group C member 3 (NR1C3), is a PPAR which serves as master regulator of adipocytes differentiation, and plays an important role in lipid metabolism or adipogenesis. Recent study showed that PPAR-γ is expressed in most tissue and also has critical impact in many metabolic homeostasis disorders.CONTENT: Dysregulation of PPAR-γ is correlated to the development of obesity, type 2 diabetes, atherosclerosis, cardiovascular disease, acute kidney injury, autoimmune disease, gastrointestinal disease and Alzheimer’s disease. Abundant number of new emerging compounds, with in vitro and in vivo effectiveness as natural and synthetic agonists of PPARs, are investigated, developed and used as the treatment of metabolic disorders of glucose and/or lipid and other diseases.SUMMARY: Based on all studies explanation, targeting PPAR-γ is proven to be a good therapeutic method for reducing negative effect of several metabolic homeostasis disorder. Now, many natural and synthetic agonists of PPARs are used as the treatment of metabolic disorders of glucose and/or lipid or another metabolic homeostasis disorder. Such agonists have different properties and specificities for individual PPARs receptors, different absorption and distribution, and distinctive gene expression profiles, which ultimately lead to different clinical outcomes.KEYWORDS: PPAR-γ, dysregulation, agonist, adipogenesis, metabolic disorder, homeostasis

Abstract

von Willebrand's disease (vWD) is an autosomally inherited bleeding disorder caused by a deficiency or abnormality of von Willebrand factor (vWF). vWF is a multimeric adhesive protein that plays an important role in primary hemostasis by promoting platelet adhesion to the subendothelium at the sites of vascular injury. It is also the carrier of factor VIII (FVIII), thus indirectly contributing to the coagulation process. Bleeding symptoms are usually mucocutaneous and postsurgical with varying severity. The diagnosis of vWD requires a personal and family history of bleeding and confirmation by laboratory analysis involving vWF antigen level, vWF ristocetin cofactor, FVIII activity, ristocetin-induced platelet aggregation, and vWF multimer analysis.KEYWORDS: von Willebrand's disease, von Willebrand factor

Abstract

BACKGROUND: Heart failure (HF) is associated with an increased expression of proinflammatory cytokines, especially soluble tumor necrosis factor receptor I (sTNFR I), but the underlying mechanism to the relationship between sTNFR I activation and the progression of HF is not yet fully understood. This study aims to see the association between sTNFR I, MMP-9, PICP, and NT-proBNP in the progression of HF.METHODS: This was a cross sectional study which recruited 45 subjects with HF confirmed by echocardiography and NT-proBNP. Concentration sTNFR I, MMP-9, and PICP were measured using ELISA method, whereas NT-proBNP concentration was measured using ECLIA method. Univariate linear regression analysis, path analysis and General Linear Model were used to determine which parameters played the most significant role in HF.RESULTS: Results of the univariate linear regression and path analysis showed there was a linear relationship between sTNFR I with MMP-9, with R square of 25.8% (p=0.00; r=0.508), R square sTNFRI and MMP-9 with PICP was 14.4% (p=0.038; r=0.379) and R square MMP-9 and PICP with NT-proBNP was 39.6% (p=0.00; r=0.629). From the General Linear Model we found that the important predictor for HF was through MMP-9 and PICP.CONCLUSION: sTNFR I as a proinflammatory factor is one of the factors involved in the heart failure as seen by NT-proBNP through activation of brosis (PICP) and remodeling factor (MMP-9).KEYWORDS: sTNFR I, MMP-9, PICP, NT-proBNP, heart failure

Abstract

BACKGROUND: Prostate cancer (PCa) was the second most common type of cancer and the fifth leading cause of cancer-related death in men. The great challenge for physicians is being able to accurately predict PCa prognosis and treatment response in order to reduce PCa-specific mortality while avoiding overtreatment by identifying of when to intervene, and in which patients.CONTENT: Currently, PCa prognosis and treatment decision of PCa involved digital rectal examination, Prostate-Speciic Antigens (PSA), and subsequent biopsies for histopathological staging, known as Gleason score. However, each procedure has its shortcomings. Efforts to find a better clinically meaningful and non-invasive biomarkers still developed involving proteins, circulating tumor cells, nucleic acids, and the ‘omics' approaches.SUMMARY: Biomarkers for PCa will most likely be an assay employing multiple biomarkers in combination using protein and gene microarrays, containing markers that are differentially expressed in PCa.KEYWORDS: prostate cancer, PSA, biomarkers, nomograms, miRNA, proteomic, genomic, metabolomic

Abstract

BACKGROUND: The mechanisms that are responsible for energy management in cells in an organism require a complex network of transcription of factors and cofactors.CONTENT: All living system must maintain a tight equilibrium between energy intake, storage and expenditure for optimal performance. This  tight equilibrium must be both robust and flexible to allow for adaptation to every situation such as exercise or rest and famine or feast. Organisms rely on finely tuned and complex signaling network to confront with all possibilities. Metabolic imbalance can cause dysfunction and pertubation of these networks, which if uncorrected will induce disease such as obesity and diabetes mellitus.SUMMARY: During the last decades the understanding of the transcriptional regulation of diverse metabolic pathways has contributed to the elucidation of mechanisms of metabolic control and to a better knowledge of the pathogenesis of metabolic diseases.

Abstract

BACKGROUND: Vascular calcification may be an important risk factor of cardiovascular disease in Chronic Kidney Disease (CKD). The pathobiology of vascular calcification in CKD is complex and involves some factors including inflammation, oxidative stress and balancing of calcification regulators. The aim of the study was to investigate the interaction between 8-isoprostane with calcification regulators such as matrix gla protein (MGP) and bone morphogenetic protein (BMP)-2 with vascular calciication in CKD.METHODS: A cross-sectional study was performed on 63 subjects undergoing haemodialysis maintenance for more than 3 months. Abdominal aortic calcification (AAC) was measured using a lateral abdominal X-ray for calcification in abdominal aorta, which is related to severity of calcific deposits at lumbar vertebral segment (L)1-L4. Serum levels of 8-isoprostane, MGP and BMP-2 were measured by enzyme-linked immunosorbent assay method.RESULTS: Results showed that 8-isoprostane levels were correlated with BMP-2 (r=0.266, p=0.018) and MGP levels (r=0.410, p≤0.001). MGP/BMP-2 levels ratio was correlated with AAC score (r=0.279, p=0.013). Subjects were then stratified into 3 groups based on AAC score: 0, 1-6 and ≥7. The highest mean of MGP levels was in AAC score 1-6 group, and the highest mean of 8-isoprostane levels was in AAC score ≥7. In the group of AAC score 0, 8-isoprostane levels were correlated with MGP levels (r=0.499, p=0.001) and MGP/BMP-2 levels ratio (r=0.291, p=0.034). In AAC score 1-6 group, 8-isoprostane levels were correlated with BMP-2 (r=0.661, p=0.005) and MGP levels (r=0.569, p=0.017). In AAC score ≥7 group, MGP levels were positively correlated with AAC score (r=0.608, p=0.041). With multivariate logistic regression analyses, we identified that increased MGP/BMP-2 levels ratio (OR=12.436; 95% CI=1.595-96.971) was an independent predictor in aortic calcification event.CONCLUSION: We concluded that regulators of calcification including calcification inhibitor and promoter related to oxidative stress, were associated with vascular calcification in CKD. MGP levels were increased in the early of calcification and MGP/BMP-2 levels ratio was a strong predictor for vascular calcification in CKD.KEYWORDS: vascular calcification, CKD, oxidative stress, 8-isoprostane, MGP, BMP-2

Abstract

BACKGROUND: Upper gastrointestinal bleeding (UGIB) is a frequent cause of emergency hospital admissions. Despite the dependency of most risk scoring systems for this disorder, the Glasgow-Blatchford bleeding score (GBS) is based on simple variables. This research intended for investigate the accuracy of a modified GBS (mGBS) to predict the severity of non-variceal UGIB.METHODS: Study conducted in Emergency Department of Dr. Saiful Anwar Hospital, Malang, from November 2012 to April 2013. Endoscopy performed between 12-24 hours after the patient stabilized. Sixty patients diagnosed were included. The accuracy of the mGBS in predicting the severity of non-variceal UGIB was compared with the full GBS using receiver operating characteristic (ROC) curve. The severity based on high risk in mGBS score compared by Forrest classification.RESULTS: For prediction of the severity of non-variceal UGIB, the GBS (AUC 0.947, 95% CI 0.87-1.03) had a slightly than the mGBS (AUC 0.943, 95% CI 0.86-1.02, p<0.01). Compared to the GBS, the mGBS was more specific (63% and 97%, respectively) but less sensitive (96% and 84%, respectively).CONCLUSION: The mGBS is an alternative diagnostic tool in predicting the severity of non-variceal UGIB.KEYWORDS: non variceal-UGIB, GBS, modified GBS

Abstract

BACKGROUND: Many previous studies have reported that central obesity is related to inflammation and endothelial dysfunction. It has also been reported that resistin can induce proinflammatory cytokines TNF-α and IL-6, which can result in endothelial dysfunction, although the role of resistin in human remains unclear. The aim of this study was to assess the role of resistin in influencing the proinflammatory cytokines TNF-α, IL-6, and chemokin MCP-1 in nondiabetic, central obese individuals. Results of this study are hoped to be useful to make a strategy for early prevention of endothelial dysfunction especially in obese individuals.METHOD: This was a cross-sectional study on 73 non diabetic obese male subjects (waist circumferences >90 cm). Resistin, hs-TNF-α, IL-6, MCP-1, VCAM-1 were assessed by ELISA. Statistical analysis was performed using SPSS for Windows v.11.5 with significance p<0.05. The correlations among biomarkers were assessed using Spearman’s Rho test.RESULTS: The study results showed a significant correlation between resistin and TNF-α (r=0.274, p<0.005), and a significant correlation between TNF-α and IL-6 (r=0.430, p<0.001). It was found that high concentration of resistin caused the concentration of TNF-α , IL-6 and MCP-1 to increase, and affected the increase of VCAM-1 (p=0.0030), A significant correlation between waist circumference and inflammation (hsCRP, r=0.296, p<0.005; IL-6, r=0.374, p<0.001 and HOMA IR, r=0.331, p<0.001) was also found.CONCLUSION: This study showed that the role of resistin in endothelial dysfunction occurred at a high concentration of resistin through induction of proinflammatory cytokines TNF-α, IL-6, and chemokin MCP-1. We suggest that inflammation in obesity starts with a positive feedback loop mechanism between resistin and TNF-α.KEYWORDS: obesity, inflammation, adipocytokines, resistin, tumor necrosis factor-α, interleukin-6, monocyte chemotactic protein-1, vascular cell adhesion molecule–1

Abstract

BACKGROUND: Adult obesity is rapidly increasing in the world including Indonesia. Tumor necrosis factor α (TNF-α) was chronically elevated in obese adipose tissue. TNF-α, a pleiotropic cytokine and also a regulator of bone formation, may might represent an important link between obesity and vascular calcification. Elegant genetic studies in mice and human have highlighted the important roles for Matrix Gla Protein (MGP) as an inhibitor of vascular calcification. The aim of this study was to examine the correlation between circulating levels of pro-inflammatory cytokines TNF-α and vascular calcification inhibitor MGP in obese men.METHODS: This was an observational cross-sectional study including 40 central obese men (waist circumference ≥90 cm) aged 31-60 years old. Serum MGP and serum TNF-α concentrations were quantified by ELISA principle. Fasting plasma glucose was assessed using hexokinase methods, triglyceride by GPO-PAP methods, and creatinine by Jaffe methods. All assays were performed according to the manufacture instruction. Statistical analysis was performed with SPSS for windows ver 16. Univariate analysis were performed to analyze mean, maximum, minimum value and SD. Pearson correlation statistic were performed to determine the correlation between variables. Significance value were define as alpha level = 0.05 based on two-tailed tests.RESULTS: The cross-sectional study (n=40) showed that the advancing age was correlated with plasma TNF-α concentration (r=0.348; p=0.028). The mean concentration of TNF-α and MGP were 8.323 and 8.368, respectively. We found a significant negative correlation between TNF-α with MGP (r=-0.425; p=0.006) and a significant correlation between TNF-α and triglyceride (r=0.375; p=0.017).CONCLUSIONS: Circulating level of TNF-α was inversely correlated with MGP concentration in obese men. This finding suggested that high level TNF-α leads to low MGP concentration obese men, hence, limits inhibitory capacity in vascular calcification.KEYWORDS: hypertension, obesity, vascular calcification, MGP, TNF-α
