BACKGROUNd: The Randomized Aldactone Evaluation study (RALEs) demonstra ted tha t spironolactone significantly improves outcomes in patients with severe heart f ailure. Use of angiotensin-converting-enzyme(ACE)-inhibitors is also indicate d in these patients. However, life-threatening hyperkalemia can occur when thes e drugs are used together. METHOds: We conducted a population-based time-serie s analysis to examine trends in the rate of spironolactone prescriptions and the rate of hospitalization for hyperkalemia in ambulatory patients before and afte r the publication of RALEs. We linked prescription-claims data and hospital-ad mission records for more than 1.3 million adults 66 years of age or older in Ont ario, Canada, for the period from 1994 through 2001. REsULTs: Among patients tre ated with ACE inhibitors who had recently been hospitalized for heart failure, t he spironolactone-prescription rate was 34 per 1000 patients in 1994, and it in creased immediately after the publication of RALEs, to 149 per 1000 patients by late 2001 (Pspitalization for hyperkalemia rose from 2.4 per 1000 patients in 1994 to 11.0 per 1000 patients in 2001 (Pd the associated mortality rose from 0.3 per 1000 to 2.0 per 1000 patients (Ps compared with expected numbers of events, there were 560(95 percent confide nce interval, 285 to 754) additional hyperkalemia-related hospitalizations and 73 (95 percent conf idence interval, 27 to 120) additional hospital deaths during 2001 among older p atients with heart failure who were treated with ACE inhibitors in Ontario. Publ ication of RALEs was not associated with significant decreases in the rates of r eadmission for heart failure or death from all causes. CONCLUsIONs: The publicat ion of RALEs was associated with abrupt increases in the rate of prescriptions f or spironolactone and in hyperkalemia- associated morbidity and mortality.

Laser ablation inductively coupled plasma mass spectrometry （LA-ICP-Ms） has been widely adopted for the direct multi-elemental analysis with high sensitivity. Especially analysis of fine ceramics by LA-ICP-Ms without time-consuming sample decomposition process has been one of the most expecting application field. small additive elements in MgO powders were analyzed by LA-ICP-Ms. For precise and accurate analysis influence of carrier gas （Ar or He） was presented by the signal intensities of ICP-Ms, relative standard deviation of signal intensities and ablated particle size d.s.ribution. Ablated particles were collected and analyzed by scanning electron microscopy （sEM） to investigate the particle size d.s.ribution, and the ablated.s.mple surface was examined by camscope. In He gas atmosphere, the signal was more stable than in Ar gas atmosphere. The signal intensity was higher in Ar than in He. Examination of ablated particles and.s.mple surface reveals that more particles were generated in Ar atmosphere and the d.s.ribution of particle size was larger.

Bio-inspired helicoidal composite laminates, inspired by the intricate helical structures found in nature, present a promising frontier for enhancing the mechanical properties of structural d.s.gns. Hence, this study provid.s.a comprehensive investigation into the nonlinear free vibration and nonlinear bending behavior of bio-inspired composite plates. The inverse hyperbolic shear deformation theory(IHsdT) of plates is employed to characterize the d.s.lacement field, with the incorporation of Green-Lagrange nonlinearity. The problem is modeled using the C0finite element method(FEM), and an in-house code is developed in the MATLAB environment to solve it numerically. Various helicoidal layup configurations including helicoidal recursive(HR), helicoidal exponential(HE), helicoidal semi-circular(Hs), linear helicoidal(LH), and Fibonacci helicoidal(FH)with different layup sequences and quasi-isotropic configurations are studied. The model is validated, and parametric studies are conducted. These studies investigate the effects of layup configurations, side-to-thickness ratio, modulus ratios, boundary conditions, and loading conditions at different load amplitud.s.on the nonlinear vibration and nonlinear bending behaviors of bio-inspired composite plates. The results show that the laminate sequence exerts a substantial impact on both nonlinear natural frequencies and nonlinear bending behaviors. Moreover, this influence varies across different side-to-thickness ratios and boundary conditions of the bio-inspired composite plate.

Background: The association between heart failure in parents and the prevalence of left ventricular systolic d.s.unction and the risk of heart failure in their offspring has not been investigated in a community-based.s.tting. Methods: We examined the cross-sectional association of heart failure in parents with the prevalence of left ventricular systolic d.s.unction, as well as left ventricular mass, internal dimensions, and wall thickness, in 1497 participants of the Framingham Offspring study(mean age, 57 years; 819 women) who underwent routine echocardiography. We also investigated prospectively whether heart failure in parents increased the risk of heart failure in 2214 offspring(mean age, 44 years; 1150 women). Results: As compared with the 1039 participants whose parents did not have heart failure, the 458 participants in the cross-sectional cohort who had at least one parent with heart failure were more likely to have increased left ventricular mass(17.0 percent vs. 26.9 percent), left ventricular internal dimensions(18.6 percent vs. 23.4 percent), and left ventricular systolic d.s.unction(3.1 percent vs. 5.7 percent); the multivariable-adjusted od.s.ratios were 1.35(95 percent confidence interval, 0.99 to 1.84), 1.29(95 percent confidence interval, 0.96 to 1.72), and 2.37(95 percent confidence interval, 1.22 to 4.61), respectively. In the longitudinal cohort, heart failure developed in 90 offspring during follow-up(mean length of follow-up, 20 years). The age-and.s.x-adjusted 10-year incidence rates of heart failure were 2.72 percent among offspring with a parent with heart failure, as compared with 1.62 percent among those without a parent with heart failure. This increase in risk persisted after multivariable adjustment(hazard ratio, 1.70; 95 percent confidence interval, 1.11 to 2.60). Conclusions: Heart failure in parents is associated with an increased prevalence of left ventricular systolic d.s.unction cross-sectionally and an elevated risk of heart fail

santalum album （Indian sandalwood） is found in the mountainous regions of the intermediate zone of sri Lanka. Few studies have been conducted on sandalwood ecology in this region, and ours is the first recorded.s.udy of essential oil content and chemical composition of heartwood. We harvested two trees with state permission and took cross-sections for analysis. We demonstrated a difference in the heartwood formation and oil yield of the trees. The composition of the oil was found to be consistent between trees and along the trunk of the tree. Main aromatic compounds were santalols and other compounds are recorded in lesser quantities. Results of this study comply with the other published work on sandalwood elsewhere. This initial study on s. album in sri Lanka provided promising results for the future of sandalwood agroforestry.
