BACKGROUND: Chronic kidney disease (CKD) is often associated with an increased risk of cardiovascular disease. Cardiovascular disease in CKD can be affected by oxidative stress and inflammation. The oxidative stress can affect arterial stiffness, especially in patients with CKD, which will increase the risk of cardiovascular disease. This study aimed to explain the correlation between total antioxidant capacity (TAC) and 8-hydroxydeoxyguanosine (8-OHdG) with carotid-femoral pulse wave velocity (cf-PWV) in patients with CKD.METHODS: Forty-three CKD patients was included in this cross-sectional study. TAC was measured from serum samples by colorimetric method and 8-OHDG was measured from urine by enzyme-linked immunoassay method. cf-PWV was measured by Doppler ultrasound as a diagnostic tool for arterial stiffness.RESULTS: Significant correlations were found between age, estimated glomerular filtration rate (e-GFR), Hemoglobin A1C (HbA1C), serum creatinine, cystatin-C, and severity of CKD with urinary 8-OHdG levels. Serum creatinine, cystatin-C, severity of CKD, age, high-density lipoprotein (HDL), e-GFR, and HbA1C also had significant correlations with serum TAC levels. Other significant correlations between e-GFR, HbA1C, serum creatinine, cystatin-C, and severity of CKD with cf-PWV were also obtained. A significant negative correlation was obtained between serum TAC and cf-PWV with moderate levels of correlation coefficient (r=-0.504).CONCLUSION: There was a negative correlation between TAC and cf-PWV, but there was no significant correlation between 8-OHdG and cf-PWV in patients with CKD.KEYWORDS: chronic kidney disease, total antioxidant capacity, 8-hydroxydeoxyguanosine, carotid-femoral pulse wave velocity

Ekokardiografi alat yang serbaguna dengan ketersedia-an dan mobililitas yang tinggi dapat digunakan pada penderita dengan keadaan gawat dengan nilai diagnosis yang cukup tinggi. Pada penelitian Hanifah dkk dibandingkan penilaian parameter diastolik (E/Ea, E/E’ atau E/e) secara non-invasif dan pemeriksaan CVP secara invasif. Pada penelitian seperti ini cara pengambilan sampel yang mudah ialah dengan purposive sampling yang dapat secara judgementatau quota. Cara terakhir yang sering digunakan dibidang kedokteran, setelah memenuhi kuota tertentu yang cukup secara statistik dengan memperhatikan kriteria inklusi dan eksklusi, penelitian diakhiri biasanya dengan pernyataan misalnya penelitian dilakukan antara periode September – November 2009 seperti pada penelitian ini.

Hipertensi Pulmonalis (Arterial) yang terjadi pada Stenosis Mitral termasuk kelompok Hipertensi Pulmonalis Arterial Sekunder akibat adanya Hipertensi Pulmonalis Venous Pasif yang dapat disebabkan berbagai penyakit yaitu antara lain trombosis vena pulmonalis dan bermacam kelainan Jantung Kiri termasuk Penyakit Katub Mitral dan katub Aorta.Dengan koreksi Stenosis Mitral (dengan peniupan balon atau pembedahan) diharapkan terjadi pe-nurunan Hipertensi Pulmonalis Arterial tersebut. Tetapi kenyataannya tidak semua penderita mengalami penurunan tekanan darah arteri pulmonalis. Pada Penelitian Irwan dkk. sekitar 21.1 % penderita masih terdapat Hipertensi Pulmonalis berat. Hal ini mudah dipahami bahwa Hipertensi Pulmonalis apapun sebabnya akhirnya akan terjadi perubahan patologi arteria pulmonalis.Pada Penyakit Jantung Bawaan (PDA, VSD besar, ASD Besar) dapat terjadi pada dekade 1 sampai ke-3 yang akhirnya menjadi Sindroma Eisenmenger. Heath dan Edwards membuat klasifikasi perubahan patologi menjadi 6 derajat. Pada Hipertensi Pulmonalis Arterial karena penyakit Mitral pun dapat mengalami perubahan patologi.

Peripheral blood mononuclear cells are a potential source of cells to be induced into pluripotent stem cells because the collection procedure is easy, minimally invasive, and can be stored in a frozen form. Small molecule compound VC6TFZ consisting of valproic acid (VPA), CHIR990210 (CHIR), 616452, Tranylcypromine, Farsokline, 3-deazaneplanocin (DZnep) and TTNPB has been shown to induce pluripotency in mouse fibroblasts, but this has not been proven in peripheral blood cells. This chemical reprogramming strategy has the potential to be used in producing the desired functional cell types for clinical applications. This study aims to determine whether the small molecule compound VC6TFZ can induce pluripotency of peripheral blood mononuclear cells to become induced pluripotent stem cells. Mononuclear cells were isolated from peripheral venous blood by density gradient centrifugation method. The cells are grouped into 4 groups. Group 1 was the control group, which was not exposed to the small molecule. Groups 2-4 were experimental groups exposed to different doses of the small molecule VC6TFZ. Identification of induced pluripotent stem cells was carried out by identifying colony morphology and pluripotent gene expression of Octamer-binding transcription factor-4 (OCT4), Sex-determining region Y-box 2 (SOX2), and Nanog using Real-Time Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR). Colonies with a round shape, large, cobble stone like, and clear boundaries resembling pluripotent stem cell colonies appeared on the 9th day of the induction process. OCT4 and Nanog gene expression were significantly increased in the treatment group compared to the control.

Estimation of fat using bioelectrical impedance analysis (BIA) is thought to be a more predictive measure of cardiovascular (CV) risk assessment than body mass index (BMI) or waist circumference (WC). Percent body fat as measured using BIA (BIA-BF%) is independently associated with future cardiovascular events namely acute myocardial infarction, ischemic heart disease. This study is conducted to determine the correlation between body fat which consists of BIA-BF%, percentage of subcutaneous adipose tissue (SAT) and visceral fat level (Visceral Adipose Tissue/VAT) measured using BIA device, BMI and WC with CV risk factors (blood pressure, blood glucose level, LDL, HDL, TG, total cholesterol, HbA1c and serum fibrinogen) in patients with acute coronary syndrome (ACS). Material and Methods : This study used a cross-sectional correlation analysis. Sample was 70 ACS patients that match with inclusion criteria. Results : We found significant correlations between BIA-BF% with diastolic blood pressure, TG, and total cholesterol (r = 0.246, r = 0.250, r = 0.348 respectively; p <0.05). There was a significant correlation between VAT with diastolic blood pressure, LDL, TG, total cholesterol, HbA1c, and fibrinogen (r = 0.299, r = 0.306, r = 0.278, r = 0.265, r = 0.292, r = 0.330 respectively, p <0.05). There was a significant correlation between the percentage SAT and HDL levels (r = 0.318; p <0.05). We found no correlation between BMI and WC with blood pressure, LDL, HDL, TG, blood glucose, HbA1c and fibrinogen levels in ACS patients. Conclusion: VAT and BIA-BF% correlate with several cardiovascular risk factors better than BMI and WC. Body fat examination using BIA may be done to manage risk factors in ACS patients.
