Early invasive compared with a selective invasive strategy in women with non-ST-elevation acute coronary syndromes: A substudy of the OASIS 5 trial and a meta-analysis of previous randomized trials
ABSTRACT The aim of this study was to compare benefits and risks of a routine invasive compared with a selective invasive strategy in women with non-ST-elevation acute coronary syndromes.
We randomly assigned 184 women, either to a routine or to a selective invasive strategy as a substudy to the OASIS 5 trial, who were followed for 2 years. Meta-analysis of data from previous randomized trials was also done. There were no significant differences between the two treatment strategies in the primary outcome death/myocardial infarction (MI)/stroke [21.0 vs. 15.4%, HR = 1.46, 95% CI (0.73-2.94)], in the secondary outcome death/MI [18.8 vs. 14.3%, HR = 1.39, 95% CI (0.67-2.88)], or separately analysed outcomes MI [12.9 vs. 13.3%, HR = 0.95, 95% CI (0.42-2.19)] or stroke [2.3 vs. 4.4%, HR = 0.67, 95% CI (0.12-3.70)]. However, there were significantly more deaths after 1 year (8.8 vs. 1.1%, HR = 9.01, 95% CI (1.11-72.90) and a higher rate of major bleeding at 30 days [8.8 vs. 1.1%, HR = 11.45, 95% CI (1.43-91.96)] in the routine invasive strategy group. A meta-analysis including 2692 women in previous randomized trials, with a gender perspective, showed no significant difference in the composite outcome death/MI, OR = 1.18, 95% CI (0.92-1.53) but a higher mortality with a routine invasive strategy for women, OR = 1.51, 95% CI (1.00-2.29).
The rate of death, MI, or stroke in women was not different in patients treated with a routine invasive strategy compared with a selective invasive strategy, but there was a concerning trend towards higher mortality. When combined with data from previous trials, there does not appear to be a benefit of an early invasive strategy in women with ACS, which differs from the results in men. These data emphasize the lack of clear evidence in favour of an invasive strategy in women and suggest caution in extrapolating the results from men to women.

Conference Paper: A dynamic model of a water treatment unit[Show abstract] [Hide abstract]
ABSTRACT: For support of field medical units, the U.S. army is developing a self-contained waste water treatment system to produce portable water for use within the unit. To aid in developing the control strategy and the fault detection/fault isolation logic, a dynamic model of the system is being developed. The first phase of the effort is to develop models of the system's components, such a ultrafiltration, reverse osmosis, ozonation, etc. These models are then combined to obtain a model for the complete system. To the greatest extent possible, fundamental equations form the basis of the models. In determining coefficients for the models, the the data was obtained from the experiments that formed the basis of the design of a pilot plant version of the unit. To refine the model, this data is then supplemented by operational data from the pilot plant.Decision and Control including the 16th Symposium on Adaptive Processes and A Special Symposium on Fuzzy Set Theory and Applications, 1977 IEEE Conference on; 01/1977
