Does transdermal estrogen reduce vascular resistance and serum cholesterol in postmenopausal women?
Equivalent reductions in vascular resistance index, norepinephrine, mean arterial pressure, and cholesterol were observed with transdermal and oral estrogens. Future studies comparing novel hormone regimens with oral hormone replacement therapy should include multiple risk markers to allow better assessment of their potential impact on coronary artery health.
Although the high frequency of multitypic HCV infection was identified in patients with multiple exposures, intergenotypic or intragenotypic recombination remains an infrequent event in southwest China; thus, routine genotyping with more than one subgenomic region for clinical use is not warranted.
