P-695 Optimizing oocyte donor stimulation: A revelation from 2,666 cases emphasizing the sole efficacy of exogenous FSH

Abstract Study question Does the administration of human menopausal gonadotrophin in controlled ovarian stimulation improve clinical outcomes in the oocyte donation program? Summary answer The addition of hMG (human menopausal gonadotropin) reduces the number of retrieved oocytes without improving embryo development or clinical outcomes in oocyte donation program. What is known already In controlled ovarian stimulation for assisted reproduction treatments, follicle stimulating hormone(FSH) is essential, but the importance of LH supplementation from menopausal origin is controversial. It is a common practice to use hMG to provide the LH effect. The standard preparation contains FSH and LH effects in a 1:1 ratio.The FSH component would recruit ovarian follicles and stimulate their growth, while the LH component would facilitate their maturation. Our aim was to compare the outcomes of intracytoplasmic sperm injection (ICSI) treatments using a gonadotropin-releasing hormone GnRH) antagonist protocol with recombinant FSH(FSHr) alone and supplemented with hMG in the oocyte donation program. Study design, size, duration This is a retrospective cohort study of 2,666 patients enrolled in the oocyte donation program at a single center over four consecutive years. Donor stimulation commenced with daily FSHr injections. The FSHr group (n = 2,078) continued FSHr, while the FSHr+hMG group (n = 588) received hMG. Participants/materials, setting, methods Donors received GnRH agonist via i.m. injection until a mean diameter >18 mm in at least eight follicles. Transvaginal oocyte retrieval was scheduled 36h later, followed by ICSI for all retrieved oocytes. Embryos were cultured in time-lapse systems and evaluated using an artificial intelligence-based model (iDAScore v2). Recipients underwent hormone replacement therapy for endometrial preparation. Our comparative study examined oocytes retrieved, embryo score, implantation, and live birth outcomes in fresh and frozen embryo transfers (ETs). Main results and the role of chance The number of retrieved oocytes was higher in the FSHr group than in the FSHr+hMG group: 24.9±10.6 vs. 18.2±8.8 (p < 0.001). In addition, embryos from the FSHr+hMG group exhibited slower early development, with significantly lower division times to two, three, four and five cells in the FSHr group (p < 0.005). However, late parameters of embryo development showed no differences. Automatic scoring by the deep learning algorithm was identical for blastocysts in the FSHr (4.8±2.8) and FSHr+hMG groups (4.8±2.8); p = 1. Implantation rates showed no significant differences for fresh ET (FSHr: 58.6% vs. FSHr+hMG: 61.9%; n = 2,073; p = 1) or frozen ET (FSHr: 49.3% vs. FSHr+hMG: 46%; n = 2,687; p = 1). Similarly, there were no differences in live birth rates for fresh ET (FSHr: 45.6% vs. FSHr+hMG: 50.3%; n = 1,993; p = 1) or frozen ET (FSHr: 31.8% vs. FSHr+hMG: 33.8%; n = 2,508; p = 1). Limitations, reasons for caution The retrospective and single-center nature of the study would be its main limitations. It is essential to emphasize that these results are only applicable within the oocyte donation program. Wider implications of the findings Based on our findings, the use of exogenous FSHr alone is likely adequate in the GnRH antagonist protocol for optimal ovarian stimulation of donors, leading to the production of high-quality embryos and successful clinical outcomes.

Intrauterine Infusion and Hysteroscopic Injection of Autologous Platelet-Rich Plasma for Patients with a Persistent Thin Endometrium: A Prospective Case-Control Study.

Objectives: To evaluate the effect of intrauterine infusion and hysteroscopic injection of autologous platelet-rich plasma (PRP) in patients with a persistent thin endometrium (EM) undergoing euploid frozen embryo transfer (EFET) cycles. Methods: This prospective case-control study enrolled 116 infertile women with thin EM (<7 mm) who underwent hormone replacement therapy (HRT) for EFET. These women had experienced at least one previous unsuccessful EFET cycle, which either resulted in the cancellation of the cycle or failure of pregnancy. A total of 55 women received an intrauterine infusion of PRP before FET, 38 received a hysteroscopic injection of PRP, and 23 received standard HRT treatment without PRP (control group). Only euploid embryos were transferred in these cycles. The primary outcomes were the implantation rate (IR) and clinical pregnancy rate (CPR) after EFET. Results: After receiving intrauterine infusion and hysteroscopic injection of PRP, 78.2% and 55.3% of patients, respectively, showed an EM thickness exceeding 7 mm, followed by embryo transfer. The hysteroscopic injection group demonstrated significantly higher IR (52%), a higher trend of CPR (52%), and a higher live birth rate (38%) than the control group (18%, 22%, and 4%). Conclusions: Intrauterine infusion and hysteroscopic injection of autologous PRP may be effective methods to increase EM thickness in HRT cycles. According to our results, both methods could increase EM thickness, while hysteroscopic injection appeared to provide more significant assistance in increasing IR, CPR, and live birth rate after EFET in patients with persistent thin EM.

Adaptation of Menopausal Spousal Support Questionnaire into Turkish: Validity and reliability study

Aim: This study focused on the pivotal role of spouses in providing comprehensive and enduring support for menopausal women. The primary objectives were to assess the validity and reliability of the Menopause Spousal Support Scale and to adapt it for use in the Turkish context. Methods: The research involved a cohort of 384 women aged 45-60, living with their husbands and not undergoing hormone replacement therapy. Data were gathered through face-to-face interviews utilizing an "Introductory Information Form" and the "Menopausal Spousal Support Questionnaire." The scale's validity was assessed through examinations of language, content, and construct, while its internal consistency and test-retest reliability were also evaluated. Results: Exploratory factor analysis unveiled a four-factor structure, accounting for 60.2% of the total variance in the scale. Confirmatory factor analysis confirmed the compatibility of the scale. The Cronbach's Alpha coefficient for the scale was 0.96. Furthermore, item-total score correlations and test-retest analysis outcomes demonstrated strong, positive, and statistically significant results. Conclusion: The Turkish adaptation of the Menopause Spousal Support Scale has been proven to be a highly valid and reliable instrument for assessing the support received by menopausal women from their spouses.

A retrospective study of ovarian tissue cryopreservation in female patients with hematological diseases for fertility preservation.

To investigate the effect and safety of ovarian tissue cryopreservation (OTC) for fertility preservation in female patients with hematological diseases. We designed a retrospective study. The clinical data of patients with hematological diseases undergoing OTC admitted to Peking University People's Hospital from April 2017 to January 2023 were analyzed and summarized. A total of 24 patients were included in the study, including 19 patients with malignant hematological diseases and 5 patients with non-malignant hematological diseases. The former included 14 patients with acute leukemia, 1 patient with chronic leukemia, and 4 patients with myelodysplastic syndrome, while the latter 5 patients were aplastic anemia (AA). 16 patients had received chemotherapy before OTC. The average age of 24 patients was 22.80 ± 6.81years. The average anti-Mullerian hormone (AMH) was 1.97 ± 2.12ng/mL, and the average follicle-stimulating hormone (FSH) was 7.01 ± 4.24IU/L in examination before OTC. FSH was greater than 10.0IU/L in 4 cases. The pre-OTC laboratory tests showed that the average white blood cell (WBC) count was (3.33 ± 1.35) × 109/L, the average hemoglobin was 91.42 ± 22.84g/L, and the average platelet was (147.38 ± 114.46) × 109/L. After injection of recombinant human granulocyte colony-stimulating factor (rhG-CSF), blood transfusion, and iron supplementation in pre-OTC treatment, the average WBC count was (4.91 ± 3.07) × 109/L, the average hemoglobin was 98.67 ± 15.43g/L, and the average platelet was (156.38 ± 103.22) × 109/L. Of the 24 patients, 22 underwent laparoscopic bilateral partial oophorectomy and oophoroplasty, and 2 underwent laparoscopic unilateral oophorectomy. The average duration of OTC was 59.54 ± 17.58min, and the average blood loss was 32.1 ± 41.6mL. The maximum blood loss was 200mL. There was no significant difference in WBC count and hemoglobin concentration after OTC compared to pre-OTC period. Only the platelet count after OTC surgery was significantly different from that before surgery ([134.54 ± 80.84 vs. 156.38 ± 103.22] × 109/L, p < 0.05). None of the 24 patients had serious complications after OTC. 2 patients had mild infection symptoms, but both recovered well. 23 patients underwent hematopoietic stem cell transplantation (HSCT) after OTC. The median and interquartile range from OTC to the pretreatment of HSCT was 33 (57) days, and the median and interquartile range from OTC to HSCT was 41 (57) days. Seven of them began pretreatment of HSCT within 20days and began HSCT within 30days after OTC. All patients were followed up. Of the 23 patients who underwent HSCT after surgery, 22 presented with amenorrhea and 1 with scanty menstrual episodes. Seven patients underwent hormone replacement therapy (HRT) after HSCT. A patient with AA underwent ovarian tissue transplantation (OTT) 3years after HSCT and resumed regular menstruation 6months after OTT. Ovarian tissue cryopreservation has a promising future in fertility protection in patients with hematological diseases. However, patients with hematological malignancies often have received gonadotoxic therapy before OTC, which may be accompanied by myelosuppression while patients with non-malignant hematological diseases often present with severe hemocytopenia. So perioperative complete blood count of patients should be paid attention to. There was no significant difference in the WBC count and hemoglobin concentration in patients with hematological diseases before and after OTC surgery, and the platelet count decreased slightly within the normal range. Infection is the most common post-OTC complication, and HSCT pretreatment can be accepted as early as the 10th day after OTC. OTC has no adverse effects on patients with hematological diseases and does not delay HSCT treatment. For young patients with hematological diseases, OTC is an effective method of fertility preservation.

Different Dosages of Progesterone in Luteal Phase Support Reflect Varying Endometrial microRNA Expression in Frozen Embryo Transfer Cycles.

Despite serum progesterone being a widely accepted method for luteal phase support during embryo transfer cycles, debates persist regarding the optimal strategy for guiding clinical decisions on progesterone dosages to maximize reproductive outcomes. This retrospective study explored the utility of microRNA (miRNA) biomarkers in guiding personalized progesterone dosage adjustments for frozen embryo transfer (FET) cycles in 22 in vitro fertilization (IVF) patients undergoing hormone replacement therapy. Utilizing MIRA, an miRNA-based endometrial receptivity test, we analyzed patients' miRNA expression profiles before and after progesterone dosage adjustments to determine suitable dosages and assess endometrial status. Despite patients receiving identical progesterone dosages, variations in miRNA profiles were observed in the initial cycle, and all patients presented a displaced window of implantation. Following dosage adjustments based on their miRNA profiles, 91% of patients successfully transitioned their endometrium towards the receptive stages. However, two patients continued to exhibit persistent displaced receptivity despite the adjustments. Given the evident variation in endometrial status and serum progesterone levels among individuals, analyzing miRNA expression profiles may address the challenge of inter-personal variation in serum progesterone levels, to deliver more personalized dosage adjustments and facilitate personalized luteal phase support in IVF.

High thrombin-activatable fibrinolysis inhibitor expression in thrombi from stroke patients in elevated estrogen states

BackgroundThe risk of acute ischemic stroke (AIS) associated with high estrogen states, including pregnant patients and those using oral contraceptives, has been well documented. We described the histological composition of thrombi collected in these cases.MethodsFrom a prospective tissue registry (STRIP registry) of thrombi retrieved during mechanical thrombectomy for AIS, we identified 5 patients with high estrogen states: 1 post-partum patient, 1 undergoing hormone replacement therapy and 3 consuming oral contraceptive pills. Five male control patients were randomly chosen matched by age. Immunohistochemistry for CD42b (platelets), von Willebrand factor (vWF), thrombin-activatable fibrinolysis inhibitor (TAFI), fibrinogen and plasminogen activator inhibitor-1 (PAI-1) was performed. Expression was quantified using Orbit Image Software. Student’s t-test was performed as appropriate.ResultsMean TAFI content for the high estrogen state group was higher than controls (25.6 ± 11.9% versus 9.3 ± 9.0%, p = 0.043*). Mean platelet content for the high estrogen state group was lower than controls (41.7 ± 10.6% versus 61.8 ± 12.9%, p = 0.029*). No significant difference was found in vWF, fibrinogen and PAI-1 expression. Mean time to recanalize was higher in the high estrogen state group compared to the control group (57.8 ± 27.6 versus 22.6 ± 11.4 min, p = 0.0351*). The mean number of passes required was higher in the high estrogen group compared to controls 4.6 versus 1.2, p = 0.0261*).ConclusionsTAFI expression, a powerful driver of thrombosis, was significantly higher in stroke thrombi among patients with high estrogen states compared to controls.

Predicting risk of endometrial failure: a biomarker signature that identifies a novel disruption independent of endometrial timing in patients undergoing hormonal replacement cycles

To propose a new gene expression signature that identifies endometrial disruptions independent of endometrial luteal phase timing and predicts if patients are at risk of endometrial failure. Multicentric, prospective study. Reproductive medicine research department in a public hospital affiliated with private fertility clinics and a reproductive genetics laboratory. Caucasian women (n = 281; 39.4 ± 4.8 years old with a body mass index of 22.9 ± 3.5 kg/m2) undergoing hormone replacement therapy between July 2018 and July 2021. Endometrial samples from 217 patients met RNA quality criteria for signature discovery and analysis. Endometrial biopsies collected in the mid-secretory phase. Endometrial luteal phase timing-corrected expression of 404 genes and reproductive outcomes of the first single embryo transfer (SET) after biopsy collection to identify prognostic biomarkers of endometrial failure. Removal of endometrial timing variation from gene expression data allowed patients to be stratified into poor (n = 137) or good (n = 49) endometrial prognosis groups on the basis of their clinical and transcriptomic profiles. Significant differences were found between endometrial prognosis groups in terms of reproductive rates: pregnancy (44.6% vs. 79.6%), live birth (25.6% vs. 77.6%), clinical miscarriage (22.2% vs. 2.6%), and biochemical miscarriage (20.4% vs. 0%). The relative risk of endometrial failure for patients predicted as a poor endometrial prognosis was 3.3 times higher than those with a good prognosis. The differences in gene expression between both profiles were proposed as a biomarker, coined the endometrial failure risk (EFR) signature. Poor prognosis profiles were characterized by 59 upregulated and 63 downregulated genes mainly involved in regulation (17.0%), metabolism (8.4%), immune response, and inflammation (7.8%). This EFR signature had a median accuracy of 0.92 (min = 0.88, max = 0.94), median sensitivity of 0.96 (min = 0.91, max = 0.98), and median specificity of 0.84 (min = 0.77, max = 0.88), positioning itself as a promising biomarker for endometrial evaluation. The EFR signature revealed a novel endometrial disruption, independent of endometrial luteal phase timing, present in 73.7% of patients. This EFR signature stratified patients into 2 significantly distinct and clinically relevant prognosis profiles providing opportunities for personalized therapy. Nevertheless, further validations are needed before implementing this gene signature as an artificial intelligence (AI)-based tool to reduce the risk of patients experiencing endometrial failure.

Thyroxine replacement by colonic route and absorption kinetics: case report

In the literature there are only 2 reports of replacement of thyroid hormones by colonic route. The objective of this study is to present a clinical case where thyroid hormone replacement was performed through the application of enemas with levothyroxine. 78-year-old patient with hypothyroidism is presented who attended to the emergency room with intestinal occlusion, which presented refractory hypothyroidism secondary to intestinal occlusion and she underwent hormone replacement with enemas with levothyroxine. The kinetics of colonic absorption of thyroid hormones takes twice as long to reach the plateau of serum levels with respect to absorption in jejunum and ileum.

Analysis of genotype and phenotype in congenital hypogonadotropic hypogonadism with reversible gonadotropin deficiency: A case report

The case involved a 32-year-old male patient who experienced delayed puberty until the age of 18. He exhibited low levels of LH, FSH, and testosterone. Chromosome karyotyping revealed a 46XY genotype, while whole exon sequencing identified a missense mutation (c.337T&gt;C) in the PROKR2 gene. Pituitary MRI did not indicate the presence of any masses, leading to a clinical diagnosis of Congenital Hypogonadotropic Hypogonadism (CHH). The patient underwent hormone replacement therapy with HCG for 3 years, followed by long-term testosterone treatment. Interestingly, the patient demonstrated spontaneous sperm production without the need for gonadotropin therapy. His wife conceived naturally on four occasions, resulting in two miscarriages and two successful deliveries, indicating a reversal of the patient’s gonadal function. Bioinformatics analysis and analysis based on the guidelines provided by the American College of Medical Genetics and Genomics (ACMG) confirmed that the missense mutation c.337T&gt;C in the PROKR2 gene was a potential pathogenic variant. However, our study indicated that this specific mutation in the PROKR2 gene could not solely account for the observed reversal of gonadal function in this patient.

Distinct roles of estrone and estradiol in endothelial colony-forming cells.

Our current understanding of the relationship between estrogen and human endothelial colony-forming cell (hECFC) function is based almost exclusively on studies investigating estradiol action at nuclear estrogen receptors. In the current study the hypothesis was tested that the less potent estrogen receptor agonist, estrone, affects hECFC proliferation, migration, secretion, and tube formation in a way that is unique from that of estradiol. The relationship between the estrogens, estradiol and estrone, is clinically important, particularly in postmenopausal women where estradiol levels wane and estrone becomes the predominant estrogen. Cultured hECFCs from peripheral blood mononuclear cell fractions were treated with concentrations of estradiol and estrone ranging from 1 nM to 1 μM separately and in combination. Following treatment, proliferation, migration, ability to attract other hECFCs (autocrine secretion), and ability to enhance endothelial cell tube formation (tubulogenesis) were tested. Functional assays revealed unique, concentration-dependent physiological effects of estrone and estradiol. Estradiol exposure resulted in increased hECFC proliferation, migration, secretion of chemoattractant, and enhancement of tube formation as expected. As with estradiol, hECFC secretion of chemoattractant increased significantly with each increase in estrone exposure. Estrone treatment produced a biphasic, concentration-dependent relationship with proliferation and tube formation and relatively no effect on hECFC migration at any concentration. The quantitative relationship between the effects of estrone and estradiol and each hECFC function was analyzed. The extent to which estrone was similar in effect to that of estradiol was dependent on both the concentrations of estradiol and estrone and the hECFC function measured. Interestingly, when the two estrogens were present, differing ratios resulted in unique functional responses. hECFCs that were treated with combinations of estrone and estradiol with high estrone to estradiol ratios showed decreased proliferative capacity. Conversely, hECFCs that were treated with combinations that were relatively high in estradiol, showed increased proliferative capacity. Cells that were treated with estrone and estradiol in equal concentrations showed an attenuated proliferative response that was decreased compared to the proliferation that either estrone or estradiol produced when they were present alone. This co-inhibitory relationship, which has not been previously reported, challenges the prevailing understanding of estrone as solely a weak agonist at estrogen receptors. This study provides evidence that estrone signaling is distinct from that of estradiol and that further investigation of estrone's mechanism of action and the biological effect may provide important insight into understanding the dysfunction and decreased number of hECFCs, and the resulting cardiovascular disease risk observed clinically in menopausal women and women undergoing hormone replacement therapy.

Associations between Menopausal Hormone Therapy and Colorectal, Lung, or Melanoma Cancer Recurrence and Mortality: A Narrative Review.

Objective: to develop eligibility criteria for use in non-gynecological cancer patients. Methods: We searched all the articles published in peer-reviewed journals up to March 2021. We utilized the PICOS standards and the following selection criteria: menopausal women with a history of non-gynecological and non-breast cancer who underwent hormone replacement therapy (HRT) using various preparations (oestrogens alone or in combination with a progestogen, tibolone, or tissue selective oestrogen complex) and different routes of administration (including oral, transdermal, vaginal, or intra-nasal). We focused on randomized controlled trials as well as relevant extension studies or follow-up reports, specifically examining recurrence and mortality outcomes. Results: Women colorectal cancer survivors who use MHT have a lower risk of death from any cause than those survivors who do not use MHT. Women who are skin melanoma survivors using MHT have a longer survival rate than non-MHT survivors. There is no evidence that women lung cancer survivors who use MHT have a different survival rate than those who do not use MHT. Conclusions: MHT is safe for women who have a history of colorectal, lung, or skin melanoma cancers.

P-555 Do IVF patients prefer the rectal route to the vaginal for luteal phase progesterone administration? - a cohort study

Abstract Study question How do IVF patients perceive rectal administration of progesterone for luteal phase support compared to vaginally administered progesterone? Summary answer Rectal administration of progesterone causes less discomfort in IVF patients, undergoing Hormone Replacement Therapy Frozen Embryo Transfer (HRT-FET) and is preferred compared to vaginal administration. What is known already Progesterone is essential for implantation and normal development of pregnancy in spontaneous pregnancies as well as in ART pregnancies. In IVF, progesterone is most often administered vaginally in Europe for luteal phase support, although, this route may cause cumbersome discharge, vaginal bleeding, and irritation of the vulva. For many years the vaginal route has been the gold standard, although, progesterone is well absorbed rectally and recent studies have shown that rectally administered micronized progesterone was well accepted among IVF patients. Until now, in IVF very little focus has been on patient convenience as regards luteal phase support. Study design, size, duration An interventional cohort study, conducted from January 2020 to November 2022 in a public fertility clinic. A total of 479 patients received a questionnaire (Q1) by e-mail during the period between the embryo transfer and the pregnancy test; A second questionnaire (Q2) was answered at the time of the first ultrasound scan in gestational week 7. Participants/materials, setting, methods Patients underwent an HRT-FET protocol, including vaginal progesterone (VP) (400mg/12hours). In patients with serum progesterone levels lower than 11 ng/ml on the 6th day of progesterone, additional progesterone was administered rectally (RP) (400mg/12hours) from that day until the day of pregnancy testing, and in pregnant patients until the first scan in week 7. Side effects and patient convenience of both routes were reported in a questionnaire, including 27 questions, using a visual analog scale (0-100). Main results and the role of chance A total of 73% of HRT-FET patients (349/479) answered Q1 before the pregnancy test and a total of 27 % (93/349) of the cohort received progesterone both vaginally and rectally. The response rate of Q2 in gestational week 7 was 100 % (221/221) and a total of 28 % of patients (62/221) administered progesterone both vaginally and rectally. In Q1, a total of 60% of patients (54/90) preferred RP over VP in the cohort of patients treated with both administration regimens. In Q2, a total of 62% of patients (37/60) preferred RP over VP in the cohort of patients treated with both administration regimens. The overall discomfort was lower in relation to RP in both questionnaires and, especially discharge was lower in RP compared to VP; median interquartile range (IQR) in Q1: 11 (3-23) vs. 50 (25-66) and Q2: 19 (9-28) vs. 47 (22-62), respectively. Changes in defecation pattern after RP were reported in Q1 as well as Q2, 48% (45/92) and 55% (34/61), however, the discomfort was reported as mild. An increased flatulence was reported by 50% (46/92) in Q1 and 63% (39/92) in Q2, however, again the discomfort was reported as mild. Limitations, reasons for caution Currently, it is unknown whether the present results apply to progesterone products other than the one used in the present study (Cyclogest®). The questionnaire used, although having been used in another published study with another progesterone product, was not specifically validated for this product. Wider implications of the findings The rectal route should be remembered for luteal phase support in IVF, and some patients might choose the rectal route over the vaginal for their luteal phase support due to less discharge.

P-521 A gene expression risk signature of endometrial failure for prognosis in In Vitro Fertilization (IVF) patients

Abstract Study question It is possible to identify a characteristic pattern of endometrial gene expression indicative of implantation failure, which is independent of implantation window displacements? Summary answer An endometrial transcriptomic signature was able to identify patients with a &amp;gt; 3-fold increased risk of implantation/pregnancy failure with 95% accuracy. What is known already Implantation failure of endometrial origin is a complex and multifactorial symptom with diverse causes, diagnosed in IVF patients after repeated failures with good quality embryos. A generation of gene expression tools have assumed that Window of implantation (WOI) displacement is the principal cause of this condition, but strategies seeking to counteract this problem by adjusting the day of embryo transfer have not yielded convincing improvements in outcomes. However, it is conceivable that other forms of endometrial disruptions, relevant to embryo implantation, could exist. New endometrial diagnostic strategies are needed to understand, diagnose and potentially treat patients affected with such problems. Study design, size, duration A prospective multicenter study between January 2018 and December 2021 recruited 281 Caucasian IVF patients (mean age of 39.4±4.8 years and BMI of 22.9±3.5 kg/m2) undergoing hormone replacement therapy and encompassing 114.5±7.2 h of progesterone administration at time of endometrial biopsy. Following experimental quality controls and clinical follow up, 186 patients who had a good quality embryo transferred in the cycle after endometrial biopsy collection were included for gene discovery and prediction performance. Participants/materials, setting, methods The expression of 404 genes selected for their potential to distinguish endometrial timing and/or endometrial disruption was measured. Transcriptomic variation related to progression of the menstrual cycle was removed using transcriptomic endometrial dating (TED) and linear models. Study groups were established according to clinical and gene expression parameters through a semi-supervised artificial intelligence procedure. Gene signature discovery and a cross-validation processes were undertaken to define predictive expression patterns. Reproductive outcomes were compared between prognosis profiles. Main results and the role of chance We developed a procedure called Clinically Acute Transcriptomic Stratification (CATranS), combining clinical parameters and deep transcriptomic molecular characterisation to stratify patients according to endometrial prognosis: ‘poor’ (n = 137) or ‘good’ (n = 49). These two transcriptomic profiles were associated with differing reproductive outcomes in the single embryo transfer following biopsy: pregnancy rate (45.1% vs 79.6%, poor vs good prognosis, respectively, p = 3.8E-5); live birth rate (56.4% vs 97.5%, p = 3.0E-06); clinical miscarriage rate (27.9% vs 2.6%, p = 0.0020); biochemical pregnancy rate (20.4% vs 0%, p = 0.0023). Patients with a poor prognosis profile had 3.3-times higher relative risk of a transferred embryo failing to implant or a pregnancy not being sustained to term, compared with good prognosis patients. Initially, a reference dataset was used to build a prototype for diagnosing endometrial failure, revealing that a gene expression signature consisting of 135 genes was the most predictive. Prediction performance was estimated using a 5-fold 100-times cross-validation process, resulting in a median accuracy of 0.92, median sensitivity of 0.96, and median specificity of 0.84. From these 135 predictive genes, 122 were differentially expressed (FDR&amp;lt;0.05) in endometrial poor prognosis, 59 up- and 63 down-regulated, most involved in functional processes such as regulation (17%), metabolism (8.4%), immune response and inflammation (7.8%). Limitations, reasons for caution We describe a potential new strategy for evaluating endometrial competence. However, to confirm predictive value, validation using additional samples from patients independent of signature discovery set is required. Further research to identify potential treatments for patients classified as poor prognosis is needed, providing a tailored clinical pathway for these patients. Wider implications of the findings The prototype described is a novel concept, potentially leading to development of a new generation of tools for diagnosis of fertility problems related to endometrial factors. The ‘poor’ prognosis profile is not caused by asynchronies in menstrual cycle progression, opening the possibility of finding new treatment pathways for these patients. Trial registration number NA

Difficulties and missteps of diagnosis and surgical treatment of patient with multifocal metachronic carcinoma associated with primary hyperparathyroidism

We present a clinical case of a patient with metachronous primary multiple carcinoma of left kidney (2004) with left adrenal metastasis (2021), occult low-grade follicular thyroid carcinoma with lateral neck lymph node metastasis (2019), central lung cancer (2020), primary hyperparathyroidism with coherent parathyroid adenomas with intrathyroid and typical location.Patient had undergone left-side nephrectomy with bilateral adrenalectomy, double-staged thyroidectomy with parathyroidectomy and selective lateral neck dissection and right-side pulmonectomy with 4 sessions of chemotherapy. Almost 20 years after first operation patient has no signs of tumors recurrence. In addition, patient is undergoing hormone replacement therapy (HRT) of adrenal insufficiency and thyroid hormone suppression therapy.This case represents combination of non-hereditary endocrine neoplasms with multiple carcinomas. It also examples mistakes and difficulties of differential diagnosis of primary adrenal tumors and adrenal metastasis.

Economic burden of comorbid insomnia in 5 common medical disease subgroups.

Approximately 85% of insomnia co-occurs with other disorders. Whereas insomnia was once considered "secondary" to these disorders, it is now widely recognized as an independent condition warranting treatment. While it is clear that insomnia can affect the course of other medical conditions, there is scant literature on the economic impact of comorbid insomnia among patients with common medical conditions. The aim of this study was to determine the economic burden of comorbid insomnia in 5 medical diseases commonly associated with insomnia: type 2 diabetes mellitus (T2DM), cancer undergoing treatment, menopause undergoing hormone replacement therapy, osteoporosis, and Alzheimer's disease and related dementias (ADRDs). This retrospective cohort study used claims data from the IBM MarketScan Commercial and Medicare Supplemental Databases from January 1, 2014, through December 31, 2019. Insomnia and comorbid disease groups were defined using physician-assigned International Classification of Diseases diagnostic codes. Insomnia medication treatment was defined based on ≥1 prescription fills for the most commonly prescribed insomnia medications (zolpidem, low-dose trazodone, and benzodiazepines [as a class]). For each comorbid disease subgroup, 4 cohorts were created: (1) patients with either treated or untreated insomnia, (2) non-sleep-disordered controls, (3) patients with untreated insomnia, and (4) patients with treated insomnia. Sample sizes for individuals with comorbid insomnia ranged from 23,168 (T2DM) to 3,015 (ADRDs). Within each disease subgroup and relative to non-sleep-disordered controls, patients with comorbid insomnia demonstrated greater adjusted health care resource utilization and costs across most points of service. Likewise, relative to individuals with untreated insomnia, those with treated insomnia generally demonstrated greater adjusted health care resource utilization and costs. In this national analysis, both untreated comorbid insomnia and comorbid insomnia treated with commonly prescribed insomnia medications were associated with increased health care resource utilization and costs across most points of service.

Abnormal Uterine Bleeding during Pubertal Induction with Transdermal Estrogen in Individuals with Turner Syndrome

Study ObjectiveIncidence of abnormal uterine bleeding (AUB) during pubertal induction among individuals with Turner syndrome (TS) has not been described previously. We estimated the incidence and characterized factors associated with AUB among individuals with TS. A secondary objective was to evaluate the management of AUB among this patient population. Design, Setting, Participants, and InterventionWe conducted a retrospective chart review to evaluate individuals with TS undergoing hormone replacement therapy (HRT) for pubertal induction with transdermal estrogen. A total of 45 participants were identified between January 2007 and June 2019. ResultsOf the 45 individuals with TS included, 16 (35%) experienced AUB. Individuals with AUB most commonly experienced prolonged (44%), prolonged and heavy (25%), and intermenstrual (19%) bleeding. Individuals who experienced AUB were more likely to experience spontaneous bleeding (69% vs 28%) and a duration of unopposed estrogen greater than 18 months (63% vs 41%), undergo progestin cycling less often than monthly (69% vs 0%), use a micronized progestin dose of less than 200 mg (25% vs 14%), and be noncompliant with HRT (19% vs 0%) compared with those who did not experience AUB. ConclusionThere is a relatively high incidence of AUB among individuals with TS undergoing pubertal induction with transdermal estrogen. Care providers should consider the clinical factors examined to guide monitoring and management of individuals with TS on HRT.

Additional single dose GnRH agonist during luteal phase support may improve live birth rate in GnRHa-HRT frozen–thawed embryo transfer cycle: a retrospective cohort study

BackgroundGnRH agonist (GnRHa) has been reported to have direct effects and functional roles in the endometrium and embryos. Several meta-analyses have shown that GnRHa administration in the luteal phase improved the live birth rate or pregnancy rate in both fresh and frozen embryo transfer (FET) cycles. The aim of this study was to investigate whether luteal GnRHa administration could also improve in vitro fertilization (IVF) outcomes in patients undergoing hormone replacement therapy (HRT) cycles with GnRHa suppression.MethodsThe retrospective cohort study included a total of 350 patients undergoing GnRHa-HRT FET cycles. The study group included 179 patients receiving an additional single dose of GnRHa in the luteal phase following embryo transfer. A total of 171 patients in the control group did not receive luteal GnRHa. The baseline and cycle characteristics and reproductive outcomes were compared between the two groups.ResultsBaseline and cycle characteristics were similar between the two groups, except lower AMH levels were found in the luteal GnRHa group than in the control group. The luteal GnRHa group had a significantly higher ongoing pregnancy rate and live birth rate than the control group. The multivariate analysis revealed that luteal GnRHa administration was positively associated with ongoing pregnancy (OR 2.04, 95% CI 1.20–3.47, P = 0.008) and live birth (OR 2.03, 95% CI 1.20–3.45, P = 0.009). When the subgroup of patients with recurrent implantation failure was analyzed, the multivariate analysis also showed that luteal GnRHa administration had beneficial effects on ongoing pregnancy (OR 4.55, 95% CI 1.69–12.30, P = 0.003) and live birth (OR 4.30, 95% CI 1.59–11.65, P = 0.004).ConclusionsOur data suggest that the addition of one luteal dose of GnRHa may improve the live birth rate in patients undergoing the GnRHa-HRT protocol.

Association between endometrial blood and clinical outcome in frozen single blastocyst transfer cycles.

Background: The success of embryo transfer cycle depends mainly on the quality of embryo and endometrial receptivity. Ultrasound examination is still the most widely used non-invasive evaluation method for its advantages of convenience, non-invasiveness and repeatability. Ultrasound-measured endometrial blood flow is one of the important evaluation indicators of morphology. Aims: To investigate the effect of the number of endometrial blood flow branches on pregnancy outcome of frozen-thawed embryo transfer cycles which have undergoing hormone replacement therapy (HRT-FET). Material and methods: A retrospective cohort study was performed looking at a total of 1390 HRT-FET cycles from our reproductive medicine center between January 2017 to December 2021, which transferred one blastocyst frozen on day 5 with good quality in morphology. Associations between endometrial blood flow branches and pregnancy outcomes were evaluated with multivariable linear regression analysis. Results: The number of endometrial blood flow branches was independently associated with clinical pregnancy (OR 1.10; 95% CI 1.02-1.20). After adjusting for potential confounders, the effect size (odds ratio) was 1.09 (95% CI 1.00-1.19), and the results showed that the clinical pregnancy rate and live birth rate of T2 and T3 groups were significantly higher than those in group T1 (p < 0.05). Subgroup analysis showed that a consistent association between the endometrial blood flow branches and clinical pregnancy in all subgroups. Conclusion: Our study provided evidence for the influence of endometrial blood flow on pregnancy outcomes. There may be an independent association between the number of endometrial blood flow branches and pregnancy outcomes in frozen-thawed single blastocyst transfer cycles.

Non-hormonal treatments of menopausal symptoms

Menopause is a natural ageing process that affects all women. It is caused by the gradual reduction in ovarian follicular function, leading to a reduction in oestrogen production. Menopause can have a variety of direct symptomatic effects – with many women affected by vasomotor (hot flushes and sweats), cardiovascular, musculoskeletal, urogenital and psychological symptoms. It is important to recognise that despite it being a natural process, menopausal symptoms can significantly affect quality of life, often co-existing with career or caring responsibilities, for example, senior roles at work or teenage children and ageing parents. The goal of this review is to aid clinicians in providing care for patients with these problems and unable to, or choosing not to, undergo hormone replacement therapy.
