Analisis Kualitas Lingkungan Perairan Berdasarkan Komunitas Meiobentos Dan Kualitas Sedimen Di Pantai Dan Area Pertambakan, Pesisir Sriwulan Kabupaten Demak (the Quality Analysis of Aquatic Environment Based on Meiobentos Community and Sediment Quality )

The objective of this study area to determine the environmental quality of coastal area and fish ponds which are on water quality, sediment quality, and Meiobentos community, to find out the relation between sediment quality and Meiobentos, and to determine the productivity level of fish ponds villages which are based on their distance, pollution level and destruction. The parameters of water quality were analyzed with descriptive comparative method, while the parameters of sediment were analyzed with principal component analysis (PCA) to find out its spatial distribution according at each monitoring station and the layer of sediment depth. Meiobentos community is to examined by factorial correspondence analysis (CA) to detect the level of its spatial distribution, which based on the monitoring station and the layer of sediment depth. Socio-economic parameters was collected by interviewing fish pond owners and tenant at the research area. It is analyzed with correlation regression to understand the influence of dependent parameter on independent parameter (the productivity of fish ponds). Then the nonparametric test statistic of Kruskall Wallis was used to differentiate the productivity at the three villages based on their distance from waste source and the destruction level of fish ponds. The research find out that water quality parameters (Muddy, TSS, NH3, NO2, beyond threshold level), negative redox potential (Eh) sediment value/reduction zone, and IMLP value are moderate. This shows the waters condition at the research area is still not stable. The results also show the low value of diversity index, the dominance of particular meiobentos organisms, and the conformity between meiobentos community. The results of Krskall Wallis statistical test point out that there is a significant differences between fish ponds productivity with the distance factor and the level of destruction in the three villages research areas, i.e Bedono, Sriwulan, Purwosari consercutively with productivity value 0.65, 0.56, 0.41 ton/hectare/year

Coronary artery dominance and the risk of adverse clinical events following percutaneous coronary intervention: insights from the prospective, randomised TWENTE trial

Aims: To investigate the prognostic value of coronary dominance for various adverse clinical events following the implantation of drug-eluting stents. Methods and results: We assessed two-year follow-up data of 1,387 patients from the randomised TWENTE trial. Based on the origin of the posterior descending coronary artery, coronary circulation was categorised into left and non-left dominance (i.e., right and balanced). Target vessel-related myocardial infarction (MI) was defined according to the updated Academic Research Consortium (ARC) definition (2x upper reference limit of creatine kinase [CK], confirmed by CK-MB elevation), and periprocedural MI (PMI) as MI ≤48 hours following PCI. One hundred and thirty-six patients (9.8%) had left and 1,251 (90.2%) non-left dominance. Target lesions were more frequently located in dominant arteries (p<0.005). Left dominance was associated with more severe calcifications (p=0.006) and more bifurcation lesions (p=0.031). Non-left dominance tended to be less frequent in men (p=0.09). Left coronary dominance was associated with more target vessel-related MI (14 [10.3%] vs. 62 [5.0%], p=0.009). Left dominance independently predicted PMI (adjusted HR 2.19, 95% CI: 1.15-4.15, p=0.017), while no difference in other clinical endpoints was observed between dominance groups. Conclusions: In the population of the TWENTE trial, we observed a higher incidence of periprocedural myocardial infarction in patients who had left coronary dominance. - See more at: http://www.pcronline.com/eurointervention/ahead_of_print/201402-11/#sthash.p3Zkzx7X.dp

Comparison of Frequency of Periprocedural Myocardial Infarction in Patients With and Without Diabetes Mellitus to Those With Previously Unknown but Elevated Glycated Hemoglobin Levels (from the TWENTE Trial)

In patients without a history of diabetes mellitus, increased levels of glycated hemoglobin (HbA1c) are associated with higher cardiovascular risk. The relation between undetected diabetes and clinical outcome after percutaneous coronary intervention is unknown. To investigate whether these patients may have an increased risk of periprocedural myocardial infarction (PMI), the most frequent adverse event after percutaneous coronary intervention, we assessed patients of the TWENTE trial (a randomized, controlled, second-generation drug-eluting stent trial) in whom HbA1c data were available. Patients were classified as known diabetics or patients without a history of diabetes who were subdivided into undetected diabetics (HbA1c ≥6.5%) and nondiabetics (HbA1c <6.5%). Systematic measurement of cardiac biomarkers and electrocardiographic assessment were performed. One-year clinical outcome was also compared. Of 626 patients, 44 (7%) were undetected diabetics, 181 (29%) were known diabetics, and 401 (64%) were nondiabetics. In undetected diabetics the PMI rate was higher than in nondiabetics (13.6% vs 3.7%, p = 0.01) and known diabetics (13.6% vs 6.1%, p = 0.11). Multivariate analysis adjusting for covariates confirmed a significantly higher PMI risk in undetected diabetics compared to nondiabetics (odds ratio 6.13, 95% confidence interval 2.07 to 18.13, p = 0.001) and known diabetics (odds ratio 3.73, 95% confidence interval 1.17 to 11.89, p = 0.03). After 1 year, target vessel MI rate was significantly higher in undetected diabetics (p = 0.02) than in nondiabetics, which was related mainly to differences in PMI. Target vessel failure was numerically larger in unknown diabetics than in nondiabetics, but this difference did not reach statistical significance (13.6% vs 8.0%, p = 0.25). In conclusion, undetected diabetics were shown to have an increased risk of PMI

Safety of second-generation drug-eluting stents three years after randomised use in the TWENTE trial

Aims: To assess three-year clinical outcome following randomised use of the second-generation Resolute zotarolimus-eluting stent (ZES) and the XIENCE V everolimus-eluting stent (EES). For Resolute ZES and randomised use, outcome data ≥3 years are relatively scarce. Methods and results: The TWENTE trial examined 1,391 patients with stable angina or non-ST-elevation acute coronary syndromes, of whom 21.6% were diabetics, 70.1% had complex B2 or C lesions and 77.4% had “off-label” indications for DES use. Three-year follow-up data were obtained in 1,381 patients (99.3%; 10 withdrawals). Adverse clinical events were independently adjudicated. The primary endpoint target vessel failure (TVF), a composite of cardiac death, target vessel-related myocardial infarction and clinically indicated target vessel revascularisation, was 12.1% for Resolute ZES and 13.4% for XIENCE V EES (p=0.50). Cardiac death rates were 1.9% vs. 3.5% (p=0.06); the other individual components of TVF also showed no significant between-group differences. The rates of definite-or-probable stent thrombosis (1.4% vs. 1.6%, p=0.82) and very late stent thrombosis (0.6% vs. 0.4%, p=1.0) did not differ between the groups. Conclusions: Three-year follow-up data of patients included in the randomised TWENTE trial demonstrated similar and sustained safety and efficacy of Resolute ZES and XIENCE V EE

Impact of previous coronary artery bypass surgery on clinical outcome after percutaneous interventions with second generation drug-eluting stents in TWENTE trial and Non-Enrolled TWENTE registry

AbstractBackgroundPatients with previous coronary artery bypass grafting (CABG) who underwent percutaneous coronary intervention (PCI) have an increased repeat revascularization rate, but data on contemporary second-generation drug-eluting stents (DES) are scarce.MethodsWe evaluated 1-year clinical outcome following secondary revascularization by PCI in patients of the TWENTE trial and non-enrolled TWENTE registry, and compared patients with previous CABG versus patients without previous CABG.ResultsOf all 1709 consecutive patients, 202 (11.8%) had previously undergone CABG (on average 11.2±8.5years ago). CABG patients were older (68.5±9.4years vs. 64.1±10.7years, P<0.001) and more often had diabetes (28.7% vs. 20.9%, P=0.01) and previous PCI (40.1% vs. 19.8%, P<0.001) compared to patients without previous CABG. Nevertheless, a higher target vessel revascularization (TVR) rate following PCI in the CABG patients (9.4% vs. 2.3%, P<0.001) was the only significant difference in clinical outcome at 1-year follow-up (available for 99.6%). Among CABG patients, the TVR rate was significantly higher in patients treated for graft lesions (n=65; 95.4% in vein grafts) than in patients treated for native coronary lesions only (n=137) (18.5% vs. 5.1%, P=0.002). Among 1638 patients with PCI of native coronary lesions only, there was only a non-significant difference in TVR between patients with previous CABG versus patients without previous CABG (5.1% vs. 2.3%, P=0.08).ConclusionsPatients with previous CABG showed a favorable safety profile after PCI with second-generation DES. Nevertheless, their TVR rate was still much higher, driven by more repeat revascularizations after PCI of degenerated vein grafts. In native coronary lesions, there was no such difference

TCT-251 Abnormal glucose metabolism and adverse event rates 12 months after treatment with contemporary drug-eluting stents:Insights from the BIO-RESORT Silent Diabetes study

BACKGROUND: Patients with abnormal glucose metabolism, including patients with undetected and thus untreated diabetes, may have higher event risks after percutaneous coronary intervention (PCI) with contemporary drug-eluting stents (DES). We assessed the prevalence and clinical impact of abnormal glucose metabolism in allcomer patients without previously known diabetes undergoing PCI. METHODS: The BIO-RESORT Silent Diabetes study, performed at Thoraxcentrum Twente, is a substudy of the randomized BIO-RESORT trial (NCT01674803). We performed an additional analysis identifying patients with an abnormal glucose metabolism by means of oral glucose tolerance testing (OGTT), and assessment of glycated hemoglobin A1c (HbA1c) with fasting plasma glucose (FPG) and clinical outcome at 12 months. RESULTS: Assessment of glucose metabolism revealed that of the 988 participants a total 330 (33.4%) patients had an abnormal metabolism, while 658 (66.6%) patients had a normal metabolism. Patients with abnormal glucose metabolism showed higher rates of the primary endpoint Target Vessel Failure (6.4% vs. 2.7%; p0.01), a composite of cardiac death, target vessel-related myocardial infarction, or target vessel revascularization. Multivariate analysis demonstrated that an abnormal glucose metabolism independently predicted adverse event risk (HR 2.2, 95%-CI:1.2-4.2). CONCLUSION: Abnormal glucose metabolism was detected in one out of three PCI all-comer patients and independently associated with a more than 2-fold higher event risk. Future intervention studies should determine whether meaningful benefits may accrue from routine glycaemia testing in such patients
