RESUMO

PURPOSE: To characterize female pediatric and adolescent patients seen for fertility preservation consultation at an academic medical center and to describe the association between demographic or clinical factors and the use of fertility preservation treatment (FPT). METHODS: This is a retrospective chart analysis of female pediatric and adolescent patients seen for fertility preservation consultation at an academic fertility center over a 14-year period from 2005 to 2019. RESULTS: One hundred six females aged 3-21 years were seen for fertility preservation consultation with a mean age of 16.6 years. Diagnoses included hematologic malignancies (41.5%), gynecologic malignancies (9.4%), other malignancies (31.1%), non-malignant hematologic disease (14.2%), and non-malignant conditions (3.8%). Overall, 64.2% of subjects pursued fertility preservation, including oocyte cryopreservation (35.8%) and ovarian tissue cryopreservation (23.6%). Overall, age, minority race, diagnosis, time since diagnosis, and median household income were not significantly associated with odds of completing an FPT procedure. Among all patients, those who underwent gonadotoxic therapy prior to consultation had a lower odds of receiving FPT (OR= 0.24, 95% CI 0.10-0.55). Among patients without chemotherapy exposure, no factors were associated with FPT. CONCLUSIONS: Among pediatric and adolescent patients at an academic center undergoing a fertility preservation consultation, there were no socioeconomic or clinical barriers to FPT use in those who had not yet undergone gonadotoxic therapy. The only factor that was negatively associated with odds of pursuing FPT was prior chemotherapy exposure.

RESUMO

OBJECTIVE: To test whether mechanical substrate stiffness would influence progesterone receptor B (PRB) signaling in fibroid cells. Uterine fibroids feature an excessive extracellular matrix, increased stiffness, and altered mechanical signaling. Fibroid growth is stimulated by progestins and opposed by anti-progestins, but a functional interaction between progesterone action and mechanical signaling has not been evaluated. DESIGN: Laboratory studies. SETTING: Translational science laboratory. PATIENT(S)/ANIMAL(S): Human fibroid cell lines and patient-matched fibroid and myometrial cell lines. INTERVENTION(S): Progesterone receptor B-dependent reporter assays and messenger RNA quantitation in cells cultured on stiff polystyrene plates (3GPa) or soft silicone plates (930KPa). Pharmacologic inhibitors of extracellular signal-related protein kinase (ERK) kinase 1/2 (MEK 1/2; PD98059), p38 mitogen-activated protein kinase (SB202190), receptor tyrosine kinases (RTKs; nintedanib), RhoA (A13), and Rho-associated coiled-coil kinase (ROCK; Y27632). MAIN OUTCOME MEASURE(S): Progesterone-responsive reporter activation. RESULT(S): Fibroid cells exhibited higher PRB-dependent reporter activity with progesterone (P4) in cells cultured on stiff vs. soft plates. Mechanically induced PRB activation with P4 was decreased 62% by PD98059, 78% by nintedanib, 38% by A13, and 50% by Y27632. Overexpression of the Rho-guanine nucleotide exchange factor (Rho-GEF), AKAP13, significantly increased PRB-dependent reporter activity. Collagen 1 messenger RNA levels were higher in fibroid cells grown on stiff vs. soft plates with P4. CONCLUSION(S): Cells cultured on mechanically stiff substrates had enhanced PRB activation via a mechanism that required MEK 1/2 and AKAP13/RhoA/ROCK signaling pathways. These studies provide a framework to explore the mechanisms by which mechanical stiffness affects progesterone receptor activation.

RESUMO

INTRODUCTION: To determine whether progestin type or number of dilation and curettage procedures (D&Cs) were associated with intrauterine synechiae (IS) or pregnancy outcomes in patients conservatively treated for endometrial intraepithelial neoplasia (EIN) or endometrial cancer (EC). MATERIALS AND METHODS: We evaluated patients conservatively treated for EIN or EC from 2000 to 2017 at an academic center. IS were identified hysteroscopically. We calculated proportions for categorical variables and tested associations between D&C number, progestin, and pregnancy outcomes using Pearson chi-squared and Fisher's exact tests. A post-hoc power analysis indicated sufficient power to detect livebirth. RESULTS: We analyzed 54 patients, 15 with EIN (28 %) and 39 with EC (72 %), with a mean age of 34 ± 1.2 years. Progestin treatment types included megestrol acetate (MA) (n = 24), MA with levonorgestrel intrauterine device (LngIUD) (n = 10), MA followed by LngIUD (n = 3), and LngIUD alone (n = 6). Mean number of D&Cs was 3.9 ± 0.9. Overall, 53 subjects underwent hysteroscopy; 10 (19 %) had IS. When D&Cs were grouped into 0-2, 3-4 and ≥5, each increase in D&C group had a 2.9 higher odds of IS (OR: 2.91, p = 0.04, CI: 1.05-10.02). LngIUD was associated with a nonsignificant 46 % decrease in the odds of IS (OR: 0.54, p = 0.66, CI: 0.08-2.87). Twenty-two women attempted pregnancy; 14 women achieved a total of 20 pregnancies and 9 women had total of 15 livebirths (41 % livebirth rate). The number of D&Cs and progestin treatment type were not associated with pregnancy outcomes. DISCUSSION: Among 54 patients conservatively treated for EC/EIN, nearly 20 % developed IS. However, hysteroscopic and/or fertility treatments may improve pregnancy outcomes.

RESUMO

IMPORTANCE: Menopause is associated with bothersome symptoms for many women, including mood changes, hot flushes, sleep problems, and fatigue. Progesterone is commonly prescribed in combination with estrogen therapy. Although monotherapy with progestins has been used as treatment of menopausal symptoms in women with contraindications to estrogens, the optimal route, and dosage of progestin monotherapy has not been established. OBJECTIVE: To assess whether progestin as a standalone treatment is effective for treating vasomotor and mood symptoms associated with menopause. EVIDENCE REVIEW: We conducted a systematic review using PubMed and Embase databases from January 1980 to January 2020. We included randomized controlled trials (RCTs) that investigated different forms of progestin for the treatment of vasomotor or mood symptoms associated with menopause. FINDINGS: A systematic search of 892 studies identified seven RCTs involving a total of 601 patients. The available literature was heterogeneous in terms of formulation and dose of progesterone; administration ranged from 5 to 60 mg of transdermal progesterone, 10 to 20 mg oral medroxyprogesterone acetate, and 300 mg of oral micronized progesterone. Duration of treatment also differed between studies, ranging from 21 days to 12 months (median: 12 wks). Three of seven RCTs reported that progestin therapy led to an improvement of vasomotor symptoms (VMS) in postmenopausal women. The largest study administering oral progestin using 300 mg micronized progesterone reported a 58.9% improvement in VMS (vs 23.5% in placebo group, n = 133), whereas the largest study using transdermal progesterone reported no improvement (n = 230). No study reported an improvement of mood symptoms. Side effects, such as headaches and vaginal bleeding, were significant in five of seven RCTs and led to discontinuation of treatment in 6% to 21% of patients. CONCLUSIONS AND RELEVANCE: A beneficial effect was reported in some trials with the transdermal route at longer duration and with oral treatment at higher doses for VMS for progesterone-only therapy. This report may help to inform future studies of progestin-only therapy for the treatment of menopausal symptoms.

RESUMO

Purpose: For prepubertal girls, or when gonadotoxic treatment is urgent, ovarian tissue cryopreservation (OTC) represents the only option for fertility preservation. We sought to determine patients' knowledge and feelings about their cryopreserved ovarian tissue. Methods: We conducted qualitative interviews with women aged 18 years or older who underwent OTC at our academic fertility center between 2006 and 2017. Subjects were recruited by phone and participated in a single telephone interview using a standardized guide. Interviews were performed until data saturation was reached. Atlas.ti software was used for content analysis. Results: We interviewed eight women with a mean age of 25.8 ± 6.1 years (range, 19-37 years). The mean age at OTC was 20.4 ± 7.5 years (range, 13-35 years). Indications for fertility preservation included hematologic cancer/disease (4/8) or gynecological cancer/BRCA2 positive (4/8). Most patients (7/8) desired future fertility. Although half of the interviewees understood the OTC procedure, only two knew that the tissue can be used for future fertility and only one was aware of the benefits for vasomotor symptoms. Five subjects expressed positive emotions regarding OTC; one felt angry that the decision was made by her parents and two were concerned that OTC might not have been a good choice. However, most subjects (5/8) expressed a desire to better understand OTC and most (5/8) wished for more education about it. Conclusion: This study identifies a significant knowledge gap among patients with cryopreserved ovarian tissue about its uses and benefits as well as a strong desire among these women for improved education about this fertility preservation modality.

RESUMO

PURPOSE: Twelve percent of women in the USA will develop invasive breast cancer in their lifetime, and that risk increases to 80% if they carry a BRCA1 or BRCA2 mutation. BRCA1/2 mutations are thought to potentially affect ovarian reserve and/or fertility. METHODS: PubMed and PubMed Central were searched for publications on ovarian reserve-related outcomes (i.e., AMH and response to controlled ovarian hyperstimulation (COH) protocols) that were reported in relation to BRCA1 and/or BRCA2 mutations from 1950 through May 2019. A meta-analysis was conducted to create forest plots and summary effect measures using Review Manager 5.3. RESULTS: This article reviews the 16 qualifying publications. There were several fundamental methodological differences in the study designs and outcome details reported in AMH studies. Summary statistics found no difference in AMH levels between BRCA1/2+ women as compared with controls (Z overall test effects p ≥ 0.45). Regarding responses to COH, there were overall non-significantly fewer total and mature numbers of oocytes retrieved in BRCA1/2+ cases as compared with controls (meta-analysis Z overall test effects p ≥ 0.40). CONCLUSIONS: While the summary measures indicate no significant differences in AMH levels between BRCA1/2+ cases and controls, readers should be aware that there are significant methodological differences in the AMH reports. Additionally, the response to COH protocols does not seem to be significantly lower in BRCA1/2 mutation carriers in the existing literature. Continued research on both of these clinical parameters would be beneficial for patient counseling.
