Context: Concentration of circulating anti-Müllerian hormone (AMH) predicts short-term (3-5 years) bone loss around menopause. Whether AMH during mid-reproductive years predicts bone health over a decade later is unknown.

Objective: To study the association of AMH levels in mid-reproductive years with bone density and turnover biomarkers measured after ∼14 years of follow-up.

Article Synopsis
  • The study examined the characteristics of women with diagnosed and probable polycystic ovary syndrome (PCOS) among 557 participants from clinics in eastern Massachusetts.* -
  • About 9.7% of the women had diagnosed PCOS, while 9.2% were classified as having probable PCOS based on specific hormonal criteria, showing similarities in irregular menstrual cycles between both groups.* -
  • While diagnosed PCOS women had a higher obesity rate (43.9%), both groups showed similar glycemic traits, suggesting it's crucial to evaluate hormonal profiles in women experiencing irregular cycles regardless of body weight.*

Objective: The aim of the study is to identify appropriate definitions and patient-reported outcome measures (PROMs) for each of the eight core outcomes previously selected for genitourinary symptoms associated with menopause: pain with sex, vulvovaginal dryness, vulvovaginal discomfort or irritation, discomfort or pain when urinating, change in most bothersome symptom, distress, bother or interference of genitourinary symptoms, satisfaction with treatment, and side effects.

Methods: We conducted a systematic review to identify possible definitions and PROMs, including their measurement properties. Identified definitions and relevant PROMs with acceptable measurement properties were entered into an international consensus process involving 28 participants from 10 countries to achieve final recommendations for each core outcome.

Objective: The aim of the study is to identify suitable definitions and patient-reported outcome measures (PROMs) to assess each of the six core outcomes previously identified through the COMMA (Core Outcomes in Menopause) global consensus process relating to vasomotor symptoms: frequency, severity, distress/bother/interference, impact on sleep, satisfaction with treatment, and side effects.

Methods: A systematic review was conducted to identify relevant definitions for the outcome of side-effects and PROMs with acceptable measurement properties for the remaining five core outcomes. The consensus process, involving 36 participants from 16 countries, was conducted to review definitions and PROMs and make final recommendations for the measurement of each core outcome.

Menopausal hormone therapy (HT) was widely used in the past, but with the publication of seminal primary and secondary prevention trials that reported an excess cardiovascular risk with combined estrogen-progestin, HT use declined significantly. However, over the past 20 years, much has been learned about the relationship between the timing of HT use with respect to age and time since menopause, HT route of administration, and cardiovascular disease risk. Four leading medical societies recommend HT for the treatment of menopausal women with bothersome menopausal symptoms.

Objective: The aim of this study was to investigate the extent to which self-reported menstrual cycle length during reproductive years is associated with menopausal symptoms and age at natural menopause at midlife.

Methods: This analysis includes 634 women who enrolled in Project Viva during pregnancy (1999-2002) and completed the midlife visit approximately 18 years later. Women self-reported menstrual cycle length at enrollment (early pregnancy) and at midlife reported total and specific menopausal symptoms using the Menopause Rating Scale as well as age at natural menopause.

Objective: The aim of this study was to evaluate the associations of a lifetime history of hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM) with menopausal symptoms in midlife.

Methods: This was a secondary analysis of women participating in Project Viva, an ongoing cohort enrolled during pregnancy. The exposure was lifetime history of HDP or GDM assessed for the index pregnancy by review of outpatient and hospital medical records and for all other pregnancies by interview or questionnaire at study entry (1999-2002) and the midlife visit (2017-2021).

Study Question: Are menstrual cycle characteristics throughout the reproductive lifespan associated with cancer risk?

Summary Answer: Irregular and long menstrual cycles throughout the reproductive lifespan were associated with increased risk of total invasive cancer, especially obesity-related cancers.

What Is Known Already: Long and irregular menstrual cycles have been associated with lower risk of pre-menopausal breast cancer and higher risk of endometrial cancer, but associations with other malignancies are less clear.

Study Design, Size, Duration: Prospective cohort study.

Large-scale studies have not addressed the knowledge level of US resident physicians regarding osteoporosis management. We gauged the knowledge level of family medicine, internal medicine, and obstetrics and gynecology resident physicians regarding osteoporosis management. In 2019, we sent an anonymous survey via e-mail to all program directors of Accreditation Council for Graduate Medical Education-accredited residency programs in family medicine, internal medicine, and obstetrics and gynecology for distribution to resident physicians.

Objective: Genitourinary symptoms, such as vaginal dryness and pain with sex, are commonly experienced by postmenopausal women. Comparing treatments for these genitourinary symptoms are restricted by the use of different outcome measures in clinical trials and the omission of outcomes, which may be relevant to women. The aim of this project was to develop a Core Outcome Set (COS) to be reported in clinical trials of treatments for genitourinary symptoms associated with menopause.

Objective: Vasomotor symptoms (VMS) (hot flashes and night sweats) affect most women over the menopause transition. Comparing the safety and effectiveness of treatments for vasomotor symptoms is limited by the use of inconsistent outcome measures, and uncertainty as to which outcomes are most important to symptomatic women. To address this, we have developed a Core Outcome Set (COS) for use in clinical trials of treatments for VMS.

Objective: Genitourinary syndrome of menopause (GSM) affects nearly 50% of postmenopausal women. Yet women fail to recognize GSM as a chronic condition and are reluctant to discuss their vaginal or sexual complaints with a health care provider. This quality improvement project implemented the Day-to-Day Impact of Vaginal Aging (DIVA) questionnaire to improve the identification and diagnosis of GSM in women ≥ 45 years of age presenting for an annual wellness examination or a vulvovaginal/genitourinary complaint.
