Abstract OBJECTIVE: We examined the measurement properties of a questionnaire (PCOSQ) measuring health-related quality of life (HRQOL) in women with the polycystic ovary syndrome (PCOS). STUDY DESIGN: This multicenter prospective randomized placebo-controlled blinded study enrolled 393 patients with PCOS at tertiary care sites. Participants were randomized to placebo or troglitazone (150 mg/d, 300 mg/d, or 600 mg/d). At baseline (n=393) and after 44 weeks of treatment (n=284) the proportion of normal menstrual cycles, the free testosterone (T) level, four objective measures of facial hair growth (hair density and hair growth rate by photography, and hair diameter and hair growth rate using plucked hairs), and a subjective assessment of the degree of hirsutism, the modified Ferriman-Gallwey (F-G) score, were determined. At both visits, patients also completed the PCOSQ. Since the trial was conducted, troglitazone has been removed from the market because of toxic effects. The PCOSQ includes 26 questions (items) that address five areas of concern (domains), including emotions, body hair, body weight, fertility, and menstruation rated on a seven-point scales in which lower scores denote higher degrees of patient concern and a lower HRQOL. RESULTS: Cronbach's alpha was >0.7 for four of five domains. Factor analysis provided moderate to strong support for the five-domain structure of the PCOSQ. Cross-sectional correlations were weak with all measures but the F-G score and hair growth (r=-.46, P < .01). The change in the F-G score showed a statistically significant (P < .01) correlation with changes in PCOSQ hair growth (r=-.22), weight (r=-.17), infertility (r=-.20), and menstruation (r=-.20). Changes in the proportion of normal menstrual cycles correlated with change in the infertility domain (r=.14, P < .03) and with the change in the menstruation domain (r=.31, P < .001). The PCOSQ proved as responsive as the F-G, and more responsive than the objective measures of hair growth, to effects of troglitazone. CONCLUSIONS: Our data provides some support for the discriminative and longitudinal validity, and appreciable support for the responsiveness, of the PCOSQ.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
