Synthesis, spectral characterization of N-benzyl isatin schiff base Cu(II), Co(II) andNi(II) complexes and their effect on cancer cell lines,,”

Abstract: The efficient antitumor drugs are ever demanding in the present scenario worldwide. The chemotherapeutic activity of isatin compounds can be achieved by chelation of transition metal ions with these bases and expanding in Nregion of these compounds. In this present study, two series of Cu(II), Co(II) and Ni(II) complexes with N-benzyl isatin and isonicotinohydrazide Schiff base ligand (L 1 ) have been synthesized and characterized by using the modern analytical techniques such as IR, NMR, UV-visible, Mass, CV, and EPR etc. All the complexes are soluble in DMF and DMSO. Elemental analysis and molar conductance values indicate that the complexes are non-electrolytes. All the complexes adopt octahedral geometry around the metal ions. DNA binding activities of the complexes Cu(II), Co(II) and Ni(II) are studied by UV-vis and also cleavage studies of complexes have been done by agarose gel electrophoresis method. Cytotoxicity experiments carried out toward human AGS-gastric cancer cell line. Interestingly, compound, L 1 -Ni was found to be excellent anticancer activity against AGS-gastric cancer cell line

METHODS: We performed a meta-analysis of randomised studies comparing patients with LMCAD treated with PCI with DES versus those treated with CABG, with respect to clinical outcomes at 1, 3 and 5years. A secondary meta-analysis was performed according to low (<32), or high (≥33) SYNTAX score. RESULTS: Five studies comprising 4595 patients were included. There was no significant difference in all-cause death at all time points or when stratified with respect to SYNTAX score. The need for repeat revascularization was significantly higher with PCI at all time-points, and regardless of SYNTAX score. There was significant association between need for repeat revascularization with PCI and diabetics (p=0.04). At 5years, non-fatal MI was higher with PCI owing to increased non-procedural events (OR 3.00; CI 1.45-6.21; p=0.003). CABG showed higher rate of stroke at 1year (OR 0.21; CI 0.07-0.63; p=0.005). There was no difference in non-fatal MI or stroke at other time points, nor according to SYNTAX score. CONCLUSIONS: PCI with DES or CABG are equivalent strategies for LMCAD up to 5years with respect to death, regardless of SYNTAX score. PCI increases the rate of non-procedural MI at 5years. CABG avoids the need for repeat revascularization, especially in diabetics, but this benefit is offset by higher rate of stroke in the first year of follow up.Peer reviewedFinal Accepted Versio

Percutaneous coronary intervention in the UK: recommendations for good practice 2015.

Over the last 35 years, there has been dramatic progress in the technology and applicability of percutaneous techniques to treat obstructive coronary heart disease. Percutaneous coronary intervention (PCI) has a considerable evidence base and it is firmly established as the most common procedure used in the invasive treatment of patients with coronary heart disease in the UK. This set of guidelines aims to address specifically issues relating to PCI and not the growing subspecialty of structural heart disease intervention. It is not intended to provide a review of the entire evidence base for coronary intervention. The evidence base relating to PCI is extensively reviewed in international guidelines and the British Cardiovascular Intervention society endorses these guidelines and their updates. The guidelines presented here focus on issues pertinent to practice within the UK and set out a recommended template to ensure optimal delivery of patient care

1-Year outcomes after transcatheter aortic valve replacement with balloon-expandable versus self-expandable valves

BACKGROUND The use of a balloon-expandable transcatheter heart valve previously resulted in a greater rate of device success compared with a self-expandable transcatheter heart valve. OBJECTIVES The aim of this study was to evaluate clinical and echocardiographic outcome data at longer term follow-up. METHODS The investigator-initiated trial randomized 241 high-risk patients with symptomatic severe aortic stenosis and anatomy suitable for treatment with both balloon- and self-expandable transcatheter heart valves to transfemoral transcatheter aortic valve replacement with either device. Patients were followed-up for 1 year, with assessment of clinical outcomes and echocardiographic evaluation of valve function. RESULTS At 1 year, the rates of death of any cause (17.4% vs. 12.8%; relative risk [RR]: 1.35; 95% confidence interval [CI]: 0.73 to 2.50; p ¼ 0.37) and of cardiovascular causes (12.4% vs. 9.4%; RR: 1.32; 95% CI: 0.63 to 2.75; p ¼ 0.54) were not statistically significantly different in the balloon- and self-expandable groups, respectively. The frequencies of all strokes (9.1% vs. 3.4%; RR: 2.66; 95% CI: 0.87 to 8.12; p ¼ 0.11) and repeat hospitalization for heart failure (7.4% vs. 12.8%; RR: 0.58; 95% CI: 0.26 to 1.27; p ¼ 0.19) did not statistically significantly differ between the 2 groups. Elevated transvalvular gradients during follow-up were observed in 4 patients in the balloon-expandable group (3.4% vs. 0%; p ¼ 0.12); all were resolved with anticoagulant therapy, suggesting a thrombotic etiology. More than mild paravalvular regurgitation was more frequent in the self-expandable group (1.1% vs. 12.1%; p ¼ 0.005). CONCLUSIONS Despite the higher device success rate with the balloon-expandable valve, 1-year follow-up of patients in CHOICE (Randomized Comparison of Transcatheter Heart Valves in High Risk Patients With Severe Aortic Stenosis: Medtronic CoreValve Versus Edwards SAPIEN XT Trial), with limited statistical power, revealed clinical outcomes after transfemoral transcatheter aortic valve replacement with both balloon- and self-expandable prostheses that were not statistically significantly different.

Epidemiologic Survey of Kawasaki Disease in Jilin from 1999 Through 2008

The epidemiologic pictures of Kawasaki disease (KD) in Jilin Province of China is still not clear. We sent a questionnaire form and diagnostic guidelines for KD to the province's 32 hospitals above the county and city level with pediatric in-patients. All patients with KD diagnosed during January 1999 through December 2008 were recruited in this survey. The incidence of KD was 1.39 to 11.07 (5.26 ± 3.97) per 100,000 children under the age of 5 years between 1999 and 2008. The ratio of male to female was 1.96 to 1. Ages at onset ranged from 58 days to 14 years. Patients under 5 years of age accounted of 88.73%. The disease occurred throughout the year, but it occurred more frequently in May to July and November. The most common cardiac abnormality was coronary artery dilatation (49.5%). Age at onset and hypoalbuminemia (<30 g/l) were selected for multivariate logistic regression equation. In conclusion, incidences of KD increased in Jilin Province. Age and gender distribution shared similarities with previous reports, and the seasonal distribution was different. Age and lower serum albumin were the most important risk factors of coronary arterial lesions (CAL) in KD. In addition, patients treated with steroids also had a possible heightened risk of contracting CAL

Prevalence of white coat hypertension in adult primary care attenders

BackgroundWhite coat hypertension (WCH) is common but such data is lacking in Malaysia. AimsTo determine the prevalence of WCH and its associated factors among healthy adults in the Malaysian primary care setting. Methods This was a cross-sectional study conducted from January to June 2014 in 5 primary care clinics in Negeri Sembilan, Malaysia. Previously healthy adult who found to have persistently elevated BP fulfilling all the inclusion and exclusion criteria of our study at clinic were recruited. The validated BP set Omron HEM7200 was used for home BP monitoring in making the diagnosis of WCH. Patients were guided to do home BP monitoring. Results A total of 105 subjects completed the study, with a response rate of 92.1 per cent. The prevalence of WCH among Malaysian primary care attenders was 52.4 per cent. There was no correlation found between WCH and socio-demographic variables. ConclusionMore WCH studies using ambulatory blood pressure monitoring with larger sample size are needed for Malaysian primary care setting. Accurate diagnosis of hypertension could have saved money on the unnecessary anti-hypertensive agents
