Study findings on hot flashes are outlined in reports from R.R. Freedman and colleagues
2007 NOV 21 -- In this recently published article, scientists in the United States conducted a study "To design and test a miniature ambulatory hot flash recorder that uses neither electrodes nor gel In the first study, putative hot flashes recorded by using a relative humidity sensor were compared with patient event marks. In the second study, relative. humidity recorded by using a complete prototype recorder was compared with sternal skin conductance recordings made on a Biolog recorder, as well as with event marks University medical center Ten healthy postmenopausal women reporting frequent hot flashes and using no medication." "Intervention(S): Body heating in laboratory Positive predictive value (PPV), sensitivity, specificity In both laboratory studies, the PPV, sensitivity, and specificity among all three measures (relative humidity, skin conductance level, event) were 100%. In the field, a relative humidity increase of 3% per minute compared with skin conductance level-detected hot flashes yielded a PPV of 95.6%, a specificity of 95.2%, and a sensitivity of 90.9%," wrote R.R. Freedman and colleagues. The researchers concluded: "Conclusion(S): This device should be useful as an endpoint in clinical trials of treatments for hot flashes. (Fertil Steril((R)) 2007;88:494-6." Freedman and colleagues published their study in Fertility and Sterility (Miniature hygrometric hot flash recorder. Fertility and Sterility, 2007;88(2):494-496).
