Adolescent menstrual cycle pattern, body mass index, endocrine and ovarian ultrasound characteristics of PCOS and future fertility, cardiovascular-, and metabolic health:a 25-year longitudinal follow-up study

STUDY QUESTION: What is the predictive value of oligomenorrhea and other PCOS diagnostic characteristics in adolescence (age 15-18 years) for future fertility and cardiovascular and metabolic health at adult age? SUMMARY ANSWER: Adolescents with oligomenorrhea are more often treated to conceive but are as likely to have as much children as those with regular periods, while persisting oligomenorrhea may associate more often with cardiovascular or metabolic problems. WHAT IS KNOWN ALREADY: Adolescents with oligomenorrhea have a high risk for adult PCOS associated with subfertility due to ovulatory disorders and long-term health risks. Longitudinal studies to estimate the extent of these risks with input starting at adolescence and covering the complete reproductive lifespan are lacking. STUDY DESIGN, SIZE, DURATION: A 25-year prospective follow-up study based on a unique population-based adolescent study on menstrual irregularities performed between 1990 and 1997, the Pubertal Onset of Menstrual Cycle abnormalities, a Prospective study (POMP study). Of the 271 invited adults, 160 (59%) participated. PARTICIPANTS/MATERIALS, SETTING, METHODS: We contacted stratified samples of the POMP study cohort two decades after the initial study for a questionnaire assessing PCOS features, fertility history, pregnancy outcome, metabolic, and cardiovascular health. One hundred and sixty subjects completed the questionnaire. The mean adolescent age was 15.3 years, and the women were 39.6 years at the time of follow-up. One hundred and eight subjects had a regular menstrual cycle as adolescents and 52 were oligomenorrheic. MAIN RESULTS AND THE ROLE OF CHANCE: Of those with adolescent regular menstrual cycles 12 never tried to conceive, 4 tried but never conceived and 92 of 96 (96%) conceived, 89 of 96 (93%) delivering at least one living child. The median number of children was two. The mean time to pregnancy (TTP) was 8.4 months in the women with regular periods as adolescents and 13.2 months in case of oligomenorrhea (P = 0.08) and subfertility was present in respectively 18% and 26%. 47 of 52 adolescents with oligomenorrhea tried to conceive and 45 succeeded to have at least one live birth. Twenty-eight per cent of the subjects reported a change over time of their menstruation pattern. Fifty per cent of the girls with adolescent oligomenorrhea developed a regular cycle and 16% of those with regular periods changed to oligomenorrhea with significantly more reported subfertility (40%, P = 0.04). In case of persistent oligomenorrhea, a significant proportion (40%) underwent fertility treatment (P = 0.04). Adult BMI did not differ between groups. The risk for pregnancy-induced hypertension or pre-eclampsia was comparable between the groups. Gestational diabetes developed in three subjects each with persistent oligo amenorrhea. Adult diabetes, hypertension, and hypercholesterolemia were also mostly reported in case of persistent oligomenorrhea. In this group, the prevalence of combined cardiovascular and metabolic problems was 14% compared to 7% in the case of regular menstrual cycles as adolescent. LIMITATIONS, REASONS FOR CAUTION: The numbers in the study are small. However, the small difference between the percentage with a least one living child of those with adolescent oligomenorrhea versus those with adolescent regular menstrual cycles is reassuring. Time to pregnancy data may have been biased by early treatment of oligomenorrheic adults. WIDER IMPLICATIONS OF THE FINDINGS: Oligomenorrheic adolescents may be reassured that their chance to have a live birth is comparable with those with a regular menstrual cycle.</p

'We don't know for sure':discussion of uncertainty concerning multigene panel testing during initial cancer genetic consultations

Pre-test counseling about multigene panel testing involves many uncertainties. Ideally, counselees are informed about uncertainties in a way that enables them to make an informed decision about panel testing. It is presently unknown whether and how uncertainty is discussed during initial cancer genetic counseling. We therefore investigated whether and how counselors discuss and address uncertainty, and the extent of shared decision-making (SDM), and explored associations between counselors' communication and their characteristics in consultations on panel testing for cancer. For this purpose, consultations of counselors discussing a multigene panel with a simulated patient were videotaped. Simulated patients represented a counselee who had had multiple cancer types, according to a script. Before and afterwards, counselors completed a survey. Counselors' uncertainty expressions, initiating and the framing of expressions, and their verbal responses to scripted uncertainties of the simulated patient were coded by two researchers independently. Coding was done according to a pre-developed coding scheme using The Observer XT software for observational analysis. Additionally, the degree of SDM was assessed by two observers. Correlation and regression analyses were performed to assess associations of communicated uncertainties, responses and the extent of SDM, with counselors' background characteristics. In total, twenty-nine counselors, including clinical geneticists, genetic counselors, physician assistants-in-training, residents and interns, participated of whom working experience varied between 0 and 25 years. Counselors expressed uncertainties mainly regarding scientific topics (94%) and on their own initiative (95%). Most expressions were framed directly (77%), e.g. We don't know, and were emotionally neutral (59%; without a positive/negative value). Counselors mainly responded to uncertainties of the simulated patient by explicitly referring to the uncertainty (69%), without providing space for further disclosure (66%). More experienced counselors provided less space to further disclose uncertainty (p <0.02), and clinical geneticists scored lower on SDM compared with other types of counselors (p <0.03). Our findings that counselors mainly communicate scientific uncertainties and use space-reducing responses imply that the way counselors address counselees' personal uncertainties and concerns during initial cancer genetic counseling is suboptimal
