Healthcare use among U.S. women aged 45 and older: total costs and costs for selected postmenopausal health risks.

The purpose of this study is to estimate the level of healthcare use and costs incurred by postmenopausal women overall and for these selected conditions: cardiovascular disease, osteoporosis, breast cancer, and gynecological cancers. National healthcare survey and discharge data were used to estimate healthcare use by women aged 45 and older. Clinical Classification for Health Policy Research (CCHPR) codes were used to identify patients whose primary diagnosis or procedure corresponded with the selected conditions. National weights were used to estimate resource use. Treatment costs were estimated using cost/charge ratios or the Medicare fee schedule to calculate costs for each individual procedure. Estimated total annual medical care treatment costs for women 45 and older were about $186 billion in 1997 dollars, including about $60.4 billion for cardiovascular disease, $12.9 billion for osteoporosis, and $5.0 billion for breast and gynecological cancers. For each condition, estimated resource use and costs are reported for hospitalization, outpatient, nursing home, and home healthcare services. Resource use and costs are also reported by age and expected source of payment. The economic burden of disease for conditions commonly affecting postmenopausal women is substantial. Prior research establishes that hormone replacement therapy (HRT) may be effective in reducing the burden of disease among women who continue preventive therapy for many years, but few at-risk women do so. New alternatives for prevention, such as selective estrogen receptor modulators (SERMs), may be effective in reducing the burden of disease among postmenopausal women.

[EEG mapping during a visuo-spatial task. Averaged maps and group statistics].

Twenty young volunteers (10 men, 10 women), righthanded, students, have been recorded in EEG cartography in different situations. We have compared the quantified EEGs when the subjects were resting, eyes closed and later, eyes opened, looking at a cartoon. The EEGs were quantified by spectral Fourier analysis and submitted to data reduction. Ten spectral parameters were computed, yielding 51 variables allowing computations and drawings of 90 EEG maps. Mean parameters, mean variables, averaged EEG maps have been computed for the entire group, between sub-groups, between hemispheres. Non-parametric permutation Fisher tests have been applied for statistical comparisons and statistical validations of the EEG maps computed between subjects. The activation of EEG tracings produced by the opening of the eyes were caracterized topographically by: mean alpha frequencies increased over temporal and rolandic areas; mean alpha amplitudes in microV divided by a factor 3 for occipital areas but unchanged in topography; mean relative amplitudes divided by a factor 2 but with a topography being more parietal than occipital for the alpha rhythm; a resonance coefficient greater over the left parietal than the right (alpha more regular), whereas it was greater over the right occipital than the left during the resting condition. Statistically for the whole group, the left hemisphere, recorded after the right, is more 'activated' in the eyes closed situation. During visual attention, the left hemisphere is less activated than the right.
