Impact of stimulation with luteinizing hormone activity on IVF outcomes in patients with polycystic ovary syndrome.

Objective: To compare in-vitro fertilization (IVF) outcomes in polycystic ovary syndrome (PCOS) patients treated with follicle stimulating hormone (FSH) alone or FSH and luteinizing hormone (LH), under freeze-all gonadotropin-releasing hormone (GnRH) antagonist protocols. Material and Methods: This retrospective study at a university center included PCOS patients, who underwent freeze-all GnRH antagonist IVF cycles between January 2013 and December 2019. They were divided into FSH-only and FSH + LH groups, focusing on pregnancy and live birth rates. Results: The study included 82 patients: 43 received FSH + LH and 39 FSH only. Baseline characteristics were similar, except for higher thyroid stimulating hormone levels in the FSH-only group. The FSH + LH group required a lower mean ± standard deviation total dose of FSH (1271.5±376.7 vs. 1407.2±645.3 IU, p=0.02), had a shorter mean cycle length (7.3±3.4 vs. 8.3±1.6 days, p=0.004), and had a higher mean number of follicles stimulated (36.9±15.9 vs. 35.9±9.7, p=0.008) compared to the FSH-only group. No significant differences in pregnancy and live birth rates were noted at first transfer, but the cumulative live birth rate was significantly higher in the FSH-only group [30 of 39 (76.9%) vs. 24 of 43 (55.8%), p=0.044]. Conclusion: LH supplementation in PCOS patients undergoing GnRH antagonist IVF protocols may impair cumulative live birth rates, despite lowering FSH requirement and reducing IVF cycle length. These results highlight the complex role of LH in IVF outcomes for PCOS patients, suggesting a need for further large studies to fully understand the impact of LH in such treatments.

Obstetrical and gynecologic implications of COVID-19: what have we learned over the first two years of the pandemic.

The rapidly evolving nature of the coronavirus disease 2019 (COVID-19) pandemic has resulted in the publication of a breadth of information in the field of Obstetrics and Gynecology. This article is an examination of the impacts of COVID-19 on women's health, specifically on pregnancy, fertility, and delays to care. We review, in brief, the clinical presentation, transmission, and definitions of post-COVID conditions. Additionally, this article explores the reassuring evidence published regarding the use of mRNA vaccines in preconception and fertility treatments.

Among high responders, is oocyte development potential different in Rotterdam consensus PCOS vs non-PCOS patients undergoing IVF?

PURPOSE: To evaluate the oocyte potential to develop to blastocyst in Rotterdam consensus PCOS in women with hyper-responses requiring freeze-all embryos. METHODS: Retrospective, single-academic center, cohort study of 205 patients who underwent freeze-all antagonist IVF cycles for OHSS risk between 2013 and 2019. Women in the PCOS group (n = 88) were diagnosed per the 2003 Rotterdam criteria. Control patients (n = 122) had no evidence of hyperandrogenism or menstrual disturbance. Data was compared by t-tests, chi-squared tests, or multivariate logistic regression (SPSS). Frozen blastocysts were Gardner's grade BB or better. RESULTS: There was no difference in terms of number of oocytes collected (PCOS vs non-PCOS 27.7 ± 9.4 vs 25.9 ± 8.2, p = 0.157), number of MII (20.7 ± 8.0 vs 19.1 ± 6.6, p = 0.130), number of 2PN fertilized (15.6 ± 7.4 vs 14.4 ± 5.9, p = 0.220), and number of frozen blastocysts (7.8 ± 4.9 vs 7.1 ± 3.8, p = 0.272). In addition, fertilization rates (74 ± 17% vs 75 ± 17%, p = 0.730), blastulation rates per 2PN (51 ± 25% vs 51 ± 25%, p = 0.869), and blastulation rates per mature oocytes (37 ± 18% vs 37 ± 15%, p = 0.984) were all comparable between PCOS and controls, respectively. Moreover, there was no difference when comparing PCOS and controls in pregnancy rates (45/81 vs 77/122, p = 0.28) and clinical pregnancy rates (34/81 vs 54/122, p = 0.75), respectively. Multivariate logistic regression controlling for confounders failed to alter these results. CONCLUSION: PCOS subjects do not seem to have altered oocyte potential as measured by number of MII oocytes collected, fertilization, and blastulation rates when compared to high-responder controls, with similar magnitude of stimulation.

The prognosis of pediatric headaches--a 30-year follow-up study.

BACKGROUND: Although headaches in childhood are common, there are few data available on their long-term prognosis. We have monitored a group of patients since diagnosis in 1983. METHODS: Patients who were part of the 20-year follow-up study in 2003 were contacted, and data were collected using a standardized telephone interview. Details of headache characteristics and identified precipitants and alleviating factors were gathered. The most effective means of controlling the headaches were also recorded. RESULTS: Follow-up was achieved for 28 of 60 patients (47%). Over the 30 years since diagnosis, eight patients (29%) reported a complete resolution of headaches, including three whose headaches resolved between the 20- and 30-year follow-up studies. The type of headache varied over the 30-year time interval with only three patients maintaining the same headache type at all four time periods of 1983, 1993, 2003, and 2013. Only one patient used prescription medication as the primary method for controlling headaches. The most commonly used intervention was nonprescription analgesia, self-relaxation and/or hypnosis, and precipitant avoidance. CONCLUSIONS: Headaches persist in approximately 70% of children 30 years after diagnosis. Encouraging children to manage their headaches with simple analgesia and precipitant avoidance appears to have long-term benefits.

Dexamethasone given to premature infants and cardiac diastolic function in early childhood.

OBJECTIVES: To determine if dexamethasone given to premature infants with bronchopulmonary dysplasia would result in cardiac diastolic dysfunction in early childhood, a topic unstudied in humans. STUDY DESIGN: We compared seven children ages 3 to 8 years born at 26 weeks' gestation and given dexamethasone for bronchopulmonary dysplasia with eight gestation-matched and age-matched control children using echocardiography to assess measures of systolic and diastolic function. All dexamethasone patients had resolved hypertrophic cardiomyopathy. RESULTS: Dexamethasone patients had the same normal τ and isovolumic relaxation time (24.9 ± 2.8 and 54.6 ± 6.3 ms) as control patients (22.1 ± 3.0 and 48.8 ± 6.7 ms). Peak A velocities were the same in dexamethasone patients as in control patients (59.5 ± 15 versus 49.4 ± 5.8 cm/s, P = .10), resulting in unchanged E:A ratios (1.89 ± 0.57 versus 2.15 ± 0.43, P = .22). Peak E velocity and E-wave deceleration times were not different. We found no significant differences in measures of systolic function (heart rate-corrected velocity of circumferential fiber shortening, wall stress, and ejection fraction). Left ventricular mass was the same between the groups confirming resolution of hypertrophic cardiomyopathy. CONCLUSIONS: These data are consistent with normal myocardial relaxation, suggesting that long-term diastolic function is reassuringly normal in children who received dexamethasone as premature infants with resolution of hypertrophic cardiomyopathy.
