To evaluate the hormonal profile in three breast cancer patients who underwent controlled ovarian stimulation in the presence of the aromatase inhibitor letrozole. PATIENTS AND METHODS: In IVF University referral center, a case series of three breast cancer patients who underwent controlled ovarian stimulation (COS) with recombinant FSH and letrozole were investigated. Ovulation was induced with hCG (case No. 1) or with GnRH agonist (case No. 2-3). The primary outcome of our study was the detection of progesterone levels in the luteal phase. RESULTS: Very high progesterone values (mean 186.6 ± 43.6 ng/mL) during the luteal phase were recorded in all three cases. CONCLUSIONS: High progesterone levels can be related to the use of letrozole independently of the most commonly used trigger regimen. Although progesterone has long been considered a protective factor against breast cancer, several studies have demonstrated that progesterone could expand a transformation-sensitive stem cell population in the mammary glands. The estrogen negative feedback effect on the hypothalamus-pituitary axis and the disruption of steroid biosynthesis and could represent an intriguing reason behind this phenomenon. Our results highlight the need to evaluate further the increase in progesterone levels in the luteal phase in women with breast cancer undergoing COS with letrozole. [ABSTRACT FROM AUTHOR]

Introduction: Ovarian hyperstimulation syndrome (OHSS) is a severe complication associated with controlled ovarian stimulation (COS). GnRH agonist (GnRH-a) triggering is considered an efficient strategy to prevent OHSS in the high-risk patient., Methods: We performed a review of 11 cases of early and severe OHSS following GnRH-a triggering and freeze-all protocol. Electronic databases were searched from inception of each database until October 2021, to identify case reports and case series that reported OHSS after GnRH-a triggering and freeze-all approach describing patient demographics, COS protocol, and patient outcomes., Results: From the literature review, it is possible to suggest that (1) following GnRH-a triggering, the risk of early and severe OHSS is not totally cancelled; (2) despite it is not possible to predict the event, polycystic ovary syndrome is the most common risk factor; (3) the use of GnRH antagonist starting from the day of PU may represent a valid strategy for preventing OHSS in women with high-risk profile; (4) following the unexpected onset of OHSS, measuring serum levels of human chorionic gonadotropin (hCG) is helpful to exclude an inadvertent exogenous administration or a pregnancy., Conclusion: The statement that OHSS risk is eliminated when GnRH-a triggering, a freeze-all strategy, and no hCG in the luteal phase may generate the idea that this event cannot occur. Although rare, these cases have been observed in a relatively short period of time., (© 2022 S. Karger AG, Basel.)

Research Question: Wilson's disease (WD) is a disorder of copper metabolism that can cause hormonal alterations. The impact of WD and its therapies on fertility is not well defined. The aim of this study was to evaluate ovarian reserve and sperm parameters in long-term treated WD patients with hepatic onset., Design: WD patients with hepatic onset treated for at least 5 years were compared with healthy controls. Men underwent spermiogram and sperm DNA fragmentation (SDF) analysis. Women were tested for serum FSH, anti-Müllerian hormone (AMH) and sonographic antral follicle count (AFC) in the early follicular phase. Ovulation was monitored with ultrasound and progesterone serum concentrations in the luteal phase., Results: The WD group included 26 patients (12 males), the control group 19 subjects (9 males). All patients apart from four (one male) were responders to WD treatment. Sperm count and morphology were comparable between cases and controls. Sperm motility (total and after 1 h) was significantly lower in cases (44.78 ± 21.65%; 47.85 ± 21.52%) than controls (61.88 ± 11.03; 69.44 ± 11.02%, P = 0.03 and 0.01, respectively). The only non-responder had severe oligo-astheno-teratozoospermia. SDF values were normal in cases and controls. AMH, AFC and FSH did not differ between cases and controls. LH was significantly lower in cases (3.36 ± 1.65 mIU/ml) than controls (6.25 ± 1.03 mIU/ml, P < 0.0001). A non-responder woman who developed neurological signs had a 7-year history of infertility., Conclusions: WD patients with hepatic onset, diagnosed early and treated, have no impairment in fertility potential even if males show reduced sperm motility and females lower LH values. Only patients with poor disease control have some evidence of impaired fertility., (Copyright © 2020 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.)

The POSEIDON ( P atient- O riented S trategies E ncompassing I ndividualize D O ocyte N umber) criteria were developed to help clinicians identify and classify low-prognosis patients undergoing assisted reproductive technology (ART) and provide guidance for possible therapeutic strategies to overcome infertility. Since its introduction, the number of published studies using the POSEIDON criteria has increased steadily. However, a critical analysis of existing evidence indicates inconsistent and incomplete reporting of critical outcomes. Therefore, we developed guidelines to help researchers improve the quality of reporting in studies applying the POSEIDON criteria. We also discuss the advantages of using the POSEIDON criteria in ART clinical studies and elaborate on possible study designs and critical endpoints. Our ultimate goal is to advance the knowledge concerning the clinical use of the POSEIDON criteria to patients, clinicians, and the infertility community., Competing Interests: SE and CA declare receipt of unrestricted research grants from Merck and lecture fees from Merck.

The transfer of cryopreserved blastocysts is increasing in IVF centres. However, little is known about the perinatal and obstetric outcomes of this procedure. In an attempt to further elucidate these issues, a systematic review and meta-analysis was conducted to compare cryopreserved transfer with fresh blastocyst embryo transfer. The results show that the risk of both preterm (odds ratio [OR] 0.89, 95% confidence interval [CI] 0.80-0.99, P = 0.04) and low birthweight births (OR 0.82, 95% CI 0.68-0.99, P = 0.04) was significantly lower after cryopreserved blastocyst transfer than after fresh blastocyst transfer. The rate of large for gestational age births was significantly higher (OR 1.68, 95% CI 1.55-1.82, P < 0.00001) and the rate of small for gestational age births significantly lower (OR 0.59, 95% CI 0.54-0.65, P < 0.00001) after cryopreserved blastocyst transfer. The transfer of cryopreserved blastocysts was associated with a significantly lower risk of placental abruption (OR 0.58, 95% CI 0.40-0.83, P = 0.003) but a significantly higher risk of Caesarean section (OR 1.21, 95% CI 1.01-1.43, P = 0.03). In conclusion, the perinatal and obstetric outcomes associated with the transfer of cryopreserved blastocysts differ from those associated with fresh blastocyst transfer., (Copyright © 2020 Reproductive Healthcare Ltd.

Objective: A systematic review was carried out to summarize the available evidence to assess whether circulating nucleic acids in maternal plasma and serum (CNAPS) have the potential to serve as extra and independent markers for the prediction and/or progression monitoring of the most common and severe complications of pregnancy, including preeclampsia, intrauterine growth restriction, preterm delivery, morbidly adherent placenta, gestational diabetes, antiphospholipid syndrome, threatened abortion, intrahepatic cholestasis of pregnancy, and hyperemesis gravidarum., Method: A comprehensive literature search of the MEDLINE (PubMed), EMBASE, and ISI Web of Knowledge databases was conducted to identify relevant studies that included amounts of CNAPS in the abovementioned pregnancy complications., Results: Eighty-three studies met the eligibility criteria. The vast majority of studies were conducted on the quantity of total circulating cell free DNA (cfDNA) and cell free fetal DNA (cffDNA), and some were conducted on messenger RNA (mRNA) species. A few studies have instead evaluated the cell free DNA fetal fraction (cfDNAff), but only in a limited number of pregnancy complications. Despite the growing interest and the abundance of the papers available, little information is available for other new CNAPS, including microRNA (miRNA), long noncoding RNA (lncRNA), mitochondrial DNA (mtDNA), and circular RNA., Conclusion: Due to the heterogeneity of the populations enrolled, the scarcity of the studies that adjusted the CNAPS values for possible confounding factors, and the difficulty in interpreting the published data, no conclusion regarding the statistical robustness and clinical relevance of the data can be made at present. If assayed at the third trimester, the CNAPS have, however, shown better performance, and could be used in populations already at risk of developing complications as suggested by the presence of other clinical features. Other CNAPS, including miRNA, are under investigation, especially for the screening of gestational diabetes mellitus, but no data about their clinical utility are available. Circulating DNA (cfDNA, cffDNA, and cfDNAff) and mRNA have not been properly evaluated yet, especially in patients asymptomatic early in pregnancy but who developed complications later, perhaps because of the high cost of these techniques and the availability of other predictors of pregnancy complications (biochemical, biophysical, and ultrasound markers). Therefore, from the analysis of the data, the positive predictive value is not available. As regards the new CNAPS, including miRNA, there are still no sufficient data to understand if they can be promising markers for pregnancy complications monitoring and screening, since CNAPS are statistically weak and expensive. It is reasonable to currently conclude that the use of the CNAPS in clinical practice is not recommended.

The management of patients with a poor ovarian response (POR) to ovarian stimulation represents a challenging issue in reproductive medicine. Apart from economic burdens, the patient with POR has poor prognosis in assisted reproductive technology (ART), which represents a common cause of drop-out from treatment. To introduce a more nuanced picture of POR, the POSEIDON group developed novel criteria to identify and classify patients with low prognosis who undergo ART. The primary goal of POSEIDON criteria is to offer clinicians a pragmatic system to guide therapeutic management with the mindset to obtain the number of oocytes needed for improving ART success. A novel marker of ART success, namely, the ability to obtain the number of oocytes required for achieving at least one euploid embryo for transfer in each patient, is aligned with the POSEIDON criteria. A novel prediction model (ART Calculator) is developed to help clinicians estimate the POSEIDON marker of success. Furthermore, the POSEIDON criteria can also be used to identify more homogeneous populations to test in interventional trials.

Although transcatheter aortic valve implantation (TAVI) is still currently guided by transesophageal echocardiography (TEE) in a considerable number of hospitals, exclusive angiographic (Angio) guidance seems a reasonable approach in this setting. To date, however, no studies have directly compared the outcomes of TAVI according to the imaging modality used for procedural guidance. We, therefore, used data from a large multicenter data repository to compare the outcomes of TAVI guided exclusively by Angio and ATEE. All consecutive patients with severe aortic stenosis who underwent TAVI with the CoreValve Revalving System (CRS) in 9 Italian centers from September 2007 to March 2014, dichotomized according to the imaging support used to guide the procedure (ATEE and Angio), were included. Thirty-day and 12-month clinical outcomes were evaluated. Propensity matching analysis was performed to adjust for baseline differences. A total of 625 patients were included (256 and 369 patients were included in the ATEE and Angio groups, respectively). Patients from the ATEE more frequently underwent TAVI under general anesthesia compared with Angio group (37.9% vs 22.8%, respectively, p <0.001). Importantly, ∼80% of the patients experienced mild or even less aortic regurgitation as assessed by angiography after the procedure, without between-group differences. Postdilation and valve-in-valve rates were equivalent (24.7% vs 25%, p = 0.934 and 5.5% vs 3.4%, respectively, p = 0.217). No differences were revealed in the rates of death, cardiovascular death, and stroke or transient ischemic attack at 12-month follow-up. These results were sustained after propensity matching analysis. In conclusion, as long as a comprehensive procedural planning is performed, TAVI with CRS may be performed exclusively under angiographic guidance without the need for associated TEE., (Copyright © 2015 Elsevier Inc.

We describe the case of a patient with situs viscerum inversus totalis in whom we performed percutaneous closure of a patent foramen ovale. This case report may represent a further contribution to illustrate instrumental and interventional issues to consider in patients with situs viscerum inversus; it is also an example in which a background in embryology and congenital heart disease may aid cardiologists for the well-tolerated and effective diagnosis and treatment of adult patients with cardiac anomalies.
